Advantages of single shaft soft material shredder
The hydraulic pushing method of the single shaft soft material shredder series is the overall moving structure of the hopper. The green columns used on the injection molding machine on both sides of the main shaft are used as guide rails. The guide rail has a built-in copper sleeve. Oil action, at the same time we can choose to apply oil on the Green column to increase the lubricity and machine life.
a. Feeding is unlimited, and the feeding amount can be controlled. The hopper moves the animal material close to and away from the main shaft to ensure a smooth shredding process. The advance and retreat of materials are automatically controlled by Siemens PLC. We choose to determine the load of the spindle through the current. Effectively reduce the number of reversals, protect the reducer.
b. The structure of the traditional shredder is built-in push plate pushing material, the material and the push plate are in direct contact, and can not be lubricated, the gap between the push plate and the guide rail will become larger and larger, and eventually the push plate will be stuck and must be stopped to dismantle the push The board can continue to work.
c. At the same time, when the traditional structure has too much feed, the material cannot be taken away from the main shaft through the push plate. If the load is too high, the machine will frequently reverse, and the number of reverse rotations will damage the gear of the gearbox and reduce the service life.
The main shaft of the single shaft soft material shredder series adopts the forging circle in the round steel as the raw material, which has higher density and higher strength. AVerMedia is then tempered, forged, and roughened to achieve the standard shape. The finishing of the main shaft is all processed and formed in one's own machining center. The tolerance of the shaft can be controlled within 10 wires (1mm is equal to 100 wires).
The design of the main shaft and cutter head structure of the shredder is perfected by our company's nearly ten years of field production experience. The choice of cutter head structure is stepped spiral shape, which can make the load in the shredding process more uniform and ensure smooth operation.
a. The main shaft of Xinbei is an integral forged and processed part. The traditional shredder chooses seamless steel pipe welding. The cutter head is welded to the steel pipe by welding. The welding process is high temperature. The contact points will expand and contract after the whole welding. The tolerance of the whole shaft will even reach 4 ~ 5mm. In this way, the blade gap must be large, and our blade gap can be adjusted to 0.5mm. The smaller the blade gap, the lower the load during the shredding process, the higher the machine output, the longer the service life. At the same time, the gap of the traditional structure is too large. When dealing with soft materials, the phenomenon of shaft entanglement often occurs, causing the machine to frequently reverse, which has an impact on the service life of the motor and the gearbox. The service life of the welded cutter head is much shorter than our overall structure. It often happens that the cutter head falls and damages the shredder site, and our structure cutter head will never fall.
b. The cutter head structure of the main shaft, the traditional shredder chooses the round-welded cutter head. There is only the concave and convex structure of the cutter head on the entire shaft. The gap between the fixed knife and the moving knife will be small, but the gap between the fixed knife and the main shaft will be large. Shafts often appear when shredding soft materials. Our random selection of groove type cutter head can ensure that the fixed knife clearance of the moving knife is 0.5mm, and the gap between the fixed knife and the spindle can be controlled at 1mm, and it will never be wrapped around the shaft.
Shredder wallboard processing
The wall backsplash, left and right wallboards, hopper ears of the single-axis soft material shredder series are all processed by gantry washing. The overall accuracy can be controlled within 1mm, the machine is more stable and has a longer service life.
The traditional shredder is only rough welding, without high-precision processing. The working principle of the shredder is hard to hard. If the connection is not accurate enough, the machine will shake in the later stage of operation and seriously affect the service life of the machine.
Single-axis soft material shredder series gearboxes select high-torque gearboxes with the gear surface type, and the brand is Guomao. Due to the selection of domestic brands, considering that the domestic material standards and processing technology did not meet the German standards, we chose to enlarge the method when selecting the model. The service factor of the international standard reducer is 2.2 times, and the service factor of Xinbei's reducer is 5 times. Simply put, our gearboxes are several models larger than domestic factories. Our gearboxes are equipped with water cooling systems to maximize the service life of the gearbox.
For the connection between the reduction box and the main shaft, select the coupling connection. The coupling connection is a tight fit, which can effectively relieve the backlash generated by the main shaft during the shredding process and protect the gears of the reducer. At the same time, the pin-through structure is selected in the middle of the coupling, and the recoil force is mostly carried by the pin-through. Later, it is only necessary to simply replace the pin-through, which greatly reduces the cost of use. The traditional shredder chooses the sleeve mode, that is, the main shaft of the shredder is directly inserted into the reduction box. This method is loosely matched. During the shredding process, the reduction box will shake, and the recoil of the main shaft directly acts on the gear of the reduction box. The service life of the reducer is extremely short.
The bearing housings of the single-shaft soft material shredder series are processed in one piece by the machining center, and the high tolerance of the center of the spindle is within 10 wires, which greatly improves the accuracy of installation. Because the main shaft has a solid overall structure and a high load, our bearing chooses the enlargement mode. The size of the bearing is twice that of the traditional shredder.
The installation of shredder bearings is selected by gentle fire installation, and the process requirements are strict. In order to facilitate installation, traditional factories often choose direct fire baking, the bearing inner hole is heated and easily damaged.
The original design of the single-shaft soft material shredder series puts safety first, and the hard handling equipment is equipped with vertical safety hoppers and safety protective covers. In addition, for convenient operation and maintenance, the machine is equipped with a full set of stairs, handrails and safety maintenance platform , To reduce potential safety hazards that may occur during the use of guests.
The traditional shredder is limited by the machine structure (the push plate moves and the frame is small). In order to save costs, the hopper is also a simple bell mouth, the safety factor is not high, and the risk is too great.
Electronic control system
The electric control originals of the single-shaft soft material shredder series are mostly Siemens and Schneider brands, with stable and reliable quality. The operation system of the machine selects the Siemens PLC system, which can effectively control the forward and backward of the machine hopper, and has a complete overload protection and high heat protection system. The operation panel is a Siemens text display. After the machine debugging is completed, the operator only needs to control F1 to start and F2 to automatically stop. The system will cooperate with the mobile hopper according to the amount of input materials, and effectively and automatically run the entire process automatically and stably. The degree of automation is higher, the machine is more stable, and the service life is longer.
The traditional shredder is just a simple selection button control, which cannot effectively coordinate the internal load of the hopper according to the current. The machine will frequently reverse the scene, which greatly limits the stability and service life of the machine.
The overall structure of the machine
The working process of the single shaft soft material shredder series is an overall hard-touch hard structure. Xinbei takes these into consideration. In the manufacturing process, it is more convenient to consider from the perspective of the frame and the thickness of the board. The weight of the whole machine is closer to 1.5 than the traditional machine. Times. Can achieve long-term operation.
The high-strength hydraulic system is selected for the single-shaft soft material shredder series. The large-diameter and multi-length oil pumps are selected for the oil pump. The hydraulic station has a higher capacity. The hydraulic oil pipe is the high-pressure oil pipe used on the forklift. During the working process of the machine, the hydraulic load is neutral. In simple terms, we use a larger and stronger hydraulic system to ensure that the hydraulic pressure is in a low-load working state. The hydraulic system is also equipped with water cooling to ensure stable and long-term operation.
The hydraulic system of the traditional shredder is very small, just choose the pressure structure that is enough to push the push plate. Our smallest hydraulic system can achieve a thrust of 10T, while the traditional shredder has only 3T.
