[0014] Compared with the prior art, the beneficial effects of the present invention are: 1.

By setting up a floating drive component, the moving block slides left and right on the fixed rod, driving the driven floating roller to make periodic reciprocating movements along the axial direction. Combined with the sliding block sliding up and down on the limit rod and the swinging cooperation between the rotating rod and the connecting plate in the connecting part, the driven floating roller can simultaneously generate three composite movements: axial movement, vertical displacement and angular tilting. This realizes the mechanical active breaking of entangled materials without manual intervention, with a high degree of automation, compact structure, rapid response and strong reliability. 3. By setting up a servo motor, the driven floating roller is driven to rotate by an independent servo motor. When the controller starts the anti-winding program, it can simultaneously adjust the speed of the servo motor, so that the differential speed ratio between the driven floating roller and the active fixed roller changes periodically. This enhances the impact and shearing effect of the blade on the wrapped material, effectively avoids the material from being wrapped on the blade roller, improves the self-untangling efficiency, and reduces the maintenance cost and downtime loss of the equipment.

One end of the drive roller 9 passes through the side wall of the frame 6 and is connected via a pulley or... The gear pair is connected to the external drive motor, which is fixedly installed on the outer side wall of the frame 6. The driven floating roller 10 is arranged parallel to the driving fixed roller 9 and is located to the left of the driving fixed roller 9. Its two ends are respectively installed on the front and rear side walls of the frame 6 through two sets of floating drive components, so that the driven floating roller 10 can be displaced relative to the frame 6.

The blades on the driving fixed roller 9 and the blades on the driven floating roller 10 are staggered in the axial direction, and a shearing engagement is formed when the two rollers rotate relative to each other.

[0023] The crushing component also includes: a torque sensor 11, which is installed on the outer surface of the active fixed roller 9. The front and rear side walls inside the frame 6 are provided with moving grooves 12. The torque sensor 11 is a resistance strain gauge torque sensor, which is sleeved on the output shaft end of the active fixed roller 9 and is used to detect the load torque value borne by the active fixed roller 9 during the rotation shearing process in real time. The signal output end of the torque sensor 11 is electrically connected to the signal input end of the controller 28 through a shielded cable. The moving groove 12 is a rectangular long groove, with one on each of the inner sides of the front and rear side walls of the frame 6. The two moving grooves 12 are positioned opposite each other in the horizontal direction. The length of the moving groove 12 extends horizontally in the left and right direction, and its width extends vertically, which is used to accommodate and guide the relevant components of the floating drive assembly to move in the groove.

[0024] The floating drive assembly includes: a fixed rod 13, which is fixedly installed in the inner wall of the moving groove 12; a moving block 14 is slidably installed on the outer surface of the fixed rod 13; a connecting plate 15 is fixedly installed on the side wall of the moving block 14; and a sliding groove 16 is formed on the side wall of the connecting plate 15. The fixed rod 13 is a stainless steel cylindrical rod with a polished surface, and its two ends are horizontally fixed between the left and right inner side walls of the moving groove 12 by welding or threaded connection. The moving block 14 is a rectangular metal block with a groove at its center that connects to the fixed rod. A circular through hole with an outer diameter matching the fixed rod 13 is provided. The movable block 14 is sleeved on the outer surface of the fixed rod 13 through the circular through hole and can slide back and forth along the axial direction of the fixed rod 13. The connecting plate 15 is a rectangular metal plate, which is fixedly installed on the side wall of the movable block 14 facing the internal space of the frame 6 by bolts. That is, the connecting plate 15 moves synchronously with the movable block 14. The sliding groove 16 is opened on the side wall of the connecting plate 15 away from the movable block 14. The sliding groove 16 is a long groove with a T-shaped cross section, and its length extends in the vertical direction.

[0025] The floating drive assembly also includes: a limiting rod 17, which is fixedly installed in the inner wall of the sliding groove 16. A sliding block 18 is slidably installed on the outer surface of the limiting rod 17. The side walls of the sliding block 18 are all equipped with fixing brackets 19 through connectors. The floating drive assembly also includes a drive component. The limiting rod 17 is a smooth cylindrical straight rod, and its two ends are fixed between the upper and lower inner walls of the sliding groove 16 by screws or welding, respectively. The axis of the limiting rod 17 is set in the vertical direction. The sliding block 18 is a rectangular metal block. The center of the sliding block 18 is provided with a guide hole that matches the outer diameter of the limiting rod 17. The sliding block 18 is sleeved on the outer surface of the limiting rod 17 through the guide hole and can slide back and forth in the sliding groove 16 along the axial direction of the limiting rod 17. The fixed frame 19 is a U-shaped or L-shaped metal bracket, which is installed on the side wall of the sliding block 18 facing the internal space of the frame 6 through a connector. The two ends of the driven floating roller 10 are rotatably connected to the front and rear fixed frames 19 respectively. Specifically, the end of the driven floating roller 10 is rotatably connected to the fixed frame 19 through a bearing.

[0026] The connecting components include: two fixing blocks 20, which are fixedly installed on the side wall of the sliding block 18 respectively. A rotating rod 21 is rotatably connected between the two fixing blocks 20. A connecting plate 22 is fixedly installed on the outer surface of the rotating rod 21. The side wall of the connecting plate 22 is connected to the side wall of the fixing frame 19. Both fixing blocks 20 are rectangular metal blocks, which are spaced apart in the horizontal direction and are welded or bolted to the side wall of the sliding block 18 facing the inside of the frame 6 respectively. The rotating rod 21 is a cylindrical metal shaft, and its two ends are rotatably connected to the frame 19 through bearings or bushings respectively. Between the opposing inner sidewalls of the two fixed blocks 20, the rotating rod 21 can rotate freely around its own axis. The connecting plate 22 is a rectangular metal plate with a fixing hole at its center that matches the outer diameter of the rotating rod 21. The connecting plate 22 is fitted through the fixing hole and welded to the outer surface of the rotating rod 21, rotating synchronously with the rotating rod 21. The sidewall of the fixed frame 19 is fixedly connected to the sidewall of the connecting plate 22 by bolts. With the above-mentioned connecting parts, the fixed frame 19 can swing relative to the sliding block 18 as the rotating rod 21 rotates, thereby realizing the angle tilt adjustment of the driven floating roller 10.

[0027] The driving components include: multiple first electromagnets 23, each embedded in the inner wall of the moving groove 12; multiple second electromagnets 24 embedded in the inner wall of the sliding groove 16; and a mounting groove 25 on the side wall of the fixed frame 19, on which a servo motor 26 is fixedly mounted. The output shaft of the servo motor 26 is connected to the side wall of the driven floating roller 10. Specifically, multiple first electromagnets 23 are DC electromagnets, evenly arranged and embedded in the left and right inner walls of the moving groove 12. The first electromagnets 23 on the left and right sides are arranged opposite each other. When energized, they generate magnetic force to attract or repel the moving block 14, driving the moving block 14 to move left and right along the axis of the fixed rod 13. Multiple second electromagnets 24 are DC electromagnets, arranged in the vertical direction. The second electromagnets 24 on the upper and lower inner walls of the sliding groove 16 are evenly arranged and embedded. They are arranged opposite each other on the upper and lower sides. When energized, they generate magnetic force to attract or repel the sliding block 18, driving the sliding block 18 to move up and down along the axial direction of the limiting rod 17. The fixed frame 19 is an L-shaped metal bracket. Its vertical part is connected to the sliding block 18 through the connecting plate 22, and its horizontal part extends into the frame 6. The mounting groove 25 is opened on the horizontal side wall of the fixed frame 19. The servo motor 26 is an AC servo motor, which is fixedly installed in the inner wall of the mounting groove 25 by bolts. The output shaft of the servo motor 26 is fixedly connected to the end of the driven floating roller 10 through a coupling. It is used to independently drive the driven floating roller 10 to rotate. Its speed and direction can be independently adjusted by the controller 28 to achieve differential rotation with the active fixed roller 9.

[0028] A distribution box 27 is fixedly installed on the left side wall of the support frame 1, and a controller 28 is fixedly installed on the front side wall of the front guard plate 3. The distribution box 27 is a metal enclosed box, which contains electrical components such as circuit breakers, contactors, relays and switching power supplies. It is used to provide power distribution and circuit protection for various electrical equipment in the entire production line. The distribution box 27 is connected to the external mains power or workshop power grid through cables. The controller 28 is a PLC programmable logic controller or an industrial single-chip microcomputer control unit. It has a pre-set control program. The signal input terminal of the controller 28 is electrically connected to the signal output terminal of the torque sensor 11 through shielded cables. The signal output terminal of the controller 28 is electrically connected to the first electromagnet 23, the second electromagnet 24, the servo motor 26 and the DC motor 5 through control cables. It is used to receive the torque signal fed back by the torque sensor 11 and to comprehensively control the start, stop and operating parameters of the above components based on the signal.

[0029] Both the moving block 14 and the sliding block 18 are made of iron. When the first electromagnet 23 and the second electromagnet 24 are energized, the moving block 14 and the sliding block 18 can be driven. Specifically, the moving block 14 and the sliding block 18 are made of low-carbon steel or pure iron and have excellent magnetic permeability. When the first electromagnet 23 is energized, the electromagnetic force it generates can pass through the internal space of the moving groove 12 and act directly on the iron moving block 14. By controlling the energizing sequence and current magnitude of the first electromagnet 23 at different positions in the left and right side walls of the moving groove 12, the left and right displacement and displacement speed of the moving block 14 along the fixed rod 13 can be precisely controlled. Similarly, when the second electromagnet 24 is energized, the electromagnetic force it generates can pass through the internal space of the sliding groove 16 and act directly on the iron sliding block 18. By controlling the energizing sequence and current magnitude of the second electromagnet 24 at different positions in the upper and lower side walls of the sliding groove 16, the up and down displacement and displacement speed of the sliding block 18 along the limiting rod 17 can be precisely controlled.

[0030] Working principle: In use, the material is fed into the frame 6 through the feed inlet 7 by an external conveying device or manual feeding. At the same time, the controller 28 controls the DC motor 5 to start, and the DC motor 5 drives the conveyor belt 4 to rotate at a constant speed from right to left, so as to evenly convey the material to the shearing area between the active fixed roller 9 and the driven floating roller 10. The external drive motor drives the active fixed roller 9 to rotate at a constant speed. The controller 28 simultaneously controls the servo motor 26 to drive the driven floating roller 10 to rotate in the same direction or in the opposite direction at a speed that is different from that of the active fixed roller 9. The staggered rotating blades on the surfaces of the active fixed roller 9 and the driven floating roller 10 generate shearing, tearing and squeezing effects on the material during relative rotation, so as to realize the continuous crushing and processing of the material. The crushed material particles are discharged from the discharge outlet 8 under the action of gravity and fall into the next processing step.

[0031] During this process, the torque sensor 11 continuously monitors the load torque value borne by the active fixed roller 9 and transmits the real-time torque data signal to the controller 28. When the input material contains a large amount of long strip or film-shaped material, such as woven bags, plastic film, long straw, etc., these materials are very likely to get tangled on the root of the rotating blade or the surface of the roller shaft of the active fixed roller 9 and / or the driven floating roller 10, resulting in a sharp increase in shear resistance and a corresponding increase in the load torque of the active fixed roller 9.

[0032] When the controller 28 receives a torque signal from the torque sensor 11 that exceeds a preset first torque threshold, i.e., a slight overload signal, the controller 28 determines that slight entanglement has occurred in the current shearing area and immediately starts the anti-entanglement self-untangling program. The controller 28 controls the first electromagnets 23 embedded in the left and right sidewalls of the moving groove 12 to be energized and de-energized in a preset sequence, generating alternating electromagnetic attraction forces, driving the iron moving block 14 to reciprocate along the outer surface of the fixed rod 13 in the left and right directions. The moving block 14 drives the sliding groove through the connecting plate 15. The 16 and its internal limiting rod 17 and sliding block 18 move synchronously left and right, thereby driving the driven floating roller 10 to periodically reciprocate along its axial direction through the fixed frame 19. The reciprocating amplitude is preferably ±5mm to ±10mm. The axial movement of the driven floating roller 10 causes a relative displacement in the axial direction between the rotating blade on its outer circular surface and the corresponding rotating blade on the active fixed roller 9, forming an axial tearing force. The long strip or film-shaped material wrapped around the blade root or roller shaft is broken or detached from the wrapped position under the repeated action of this alternating axial tearing force.

[0033] When the torque signal received by the controller 28 from the torque sensor 11 exceeds the preset second torque threshold, i.e., the overload signal, and the second torque threshold is greater than the first torque threshold, the controller 28 determines that severe entanglement has occurred in the current shearing area, and conventional axial movement is insufficient to quickly untangle the state. At this time, the controller 28 starts a powerful self-untangling program. While maintaining the above-mentioned left and right axial reciprocating movement, it further controls the second electromagnets 24 embedded in the upper and lower side walls of the sliding groove 16 to be energized and de-energized in sequence according to a preset timing sequence. This drives the iron sliding block 18 to reciprocate along the outer surface of the limit rod 17 in the vertical direction. The sliding block 18 drives the fixed frame 19 and the driven floating roller 10 installed on it to move up and down synchronously through the connecting piece, so that the shearing gap of the driven floating roller 10 relative to the active fixed roller 9 in the vertical direction changes periodically.

[0034] The controller 28 independently controls the second electromagnets 24 in the front and rear floating drive components, causing the sliding block 18 located in the moving groove 12 on the front side wall of the frame 6 and the sliding block 18 located in the moving groove 12 on the rear side wall of the frame 6 to move in opposite directions. That is, when the front sliding block 18 moves upward, the rear sliding block 18 moves downward. At this time, the two fixed frames 19 drive the two ends of the driven floating roller 10 to produce opposite vertical displacements through their respective connecting parts, causing the driven floating roller 10 to tilt and swing around the axis of the rotating rod 21. The front fixed frame 19... The transmission action of the connecting plate 22 and the rotating rod 21 can deflect the sliding block 18 on the front side, and the same applies to the fixed frame 19 on the rear side. This causes the overall axis of the driven floating roller 10 to form a certain cross tilt angle with the axis of the active fixed roller 9 in space. The tilt angle is preferably between 0° and 5°. This tilt posture causes the material wrapped around the surface of the driven floating roller 10 to be subjected to uneven stretching and squeezing forces along the roller axis. Under the combined action of axial component force and radial shear force, the wrapped material is quickly peeled off, broken and falls off from the roller surface, effectively relieving the severe entanglement and jamming state.

[0035] When the controller 28 receives the torque signal from the torque sensor 11 and it returns to the normal range, which is lower than the preset first torque threshold, the controller 28 determines that the entanglement has been released. Then, it controls the first electromagnet 23 and the second electromagnet 24 to return to the initial default state, so that the driven floating roller 10 is reset to the normal shearing position parallel to the active fixed roller 9, and continues to perform the conventional crushing operation.

[0036] It is worth mentioning that during the entire anti-entanglement process, the controller 28 also controls the dynamic change of the differential speed ratio between the driven floating roller 10 and the active fixed roller 9 by adjusting the speed of the servo motor 26. While the axial movement and up-and-down swinging superimposed effects are combined, the speed of the driven floating roller 10 is adjusted to produce a periodically changing speed difference with the active fixed roller 9, so that the shearing frequency of the blades on the surface of the two rollers changes instantaneously, further enhancing the dynamic impact and tearing effect on the entangled material and improving the self-untangling efficiency.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
