The grinding wheel feeding of the SQ series shredder is an important technical link. The main function of the grinding wheel is to grind the blade, keep the blade sharp and the length of the blade extended, so as to maintain the gap between the blade and the knife door. This process is crucial to ensure the quality and efficiency of shredding.

[0003] The grinding wheel is driven by a motor and both are mounted on a sliding bracket, which is mounted on the equipment and can reciprocate along the left and right directions of the equipment.

[0027] like Figure 1-5 As shown, the embodiment of the present invention proposes a grinding wheel feeding device for an SQ series wire cutting machine, including a frame 1, a sliding bracket 2 and a power mechanism are arranged on the frame 1, the sliding bracket 2 is slidably installed on the frame 1 along the left and right directions of the frame 1, and the power mechanism (not shown in the figure) is used to drive the sliding bracket 2 to reciprocate left and right on the frame 1. In this embodiment, the power mechanism can be a chain, a sprocket structure, or a screw rod 20 mechanism, and the power source is a motor. The existing related technology has fully disclosed the structure of the power mechanism, and no further description is given here. A swing arm mechanism is arranged on the sliding bracket 2, and one end of the swing arm mechanism extends out of the sliding bracket 2 to form a suspended end. The left end of the frame 1 is preset with a trigger area corresponding to the suspended end of the swing arm mechanism. The frame 1 is provided with a trigger mechanism, and the trigger mechanism includes a driving member and a trigger block 12. The driving member is used to drive the trigger block 12 to move toward or away from the trigger area. When the trigger block 12 is located in the trigger area, the movement of the sliding bracket 2 can make the swing arm mechanism contact with the trigger block 12, so that the swing arm mechanism drives the grinding wheel 4 to feed.

[0028] The frame 1 is provided with a counter 6 on one side of the moving path of the sliding bracket 2. In the present embodiment, the counter 6 is provided above the sliding bracket 2, and the counter 6 is used to record the number of reciprocating motions of the sliding bracket 2. The frame 1 is provided with a position sensor 7 above and / or below the moving path of the sliding bracket 2. In the present embodiment, 3-5 position sensors 7 are provided at equal intervals below the moving path of the sliding bracket 2, and the position sensor 7 is used to detect the position of the sliding bracket 2 on the frame 1. A controller is also included, and the power mechanism, the counter 6, the driving member, and the position sensor 7 are all electrically connected to the controller.

[0029] When the number of times the sliding bracket 2 moves left and right on the frame 1 reaches the counting threshold preset by the counter 6, the counter 6 feeds back a signal to the controller to control the operation of the driving member, so that the trigger block 12 moves toward or away from the trigger area. Through the design of the counter 6, the movement frequency of the driving member can be automatically adjusted to ensure that the feed speed of the grinding wheel 4 is constant and the processing quality is improved.

[0030] When the sliding bracket 2 moves to the preset position of the position sensor 7 on the frame 1, the position sensor 7 feeds back the signal to the controller, and the controller controls the power mechanism to drive the sliding bracket 2 to move in the preset direction, and the controller determines whether the grinding wheel 4 reaches the target position. If it reaches, the grinding wheel 4 stops feeding, and if it does not reach, the controller controls the driving member to adjust the position of the trigger block 12. The position of the grinding wheel 4 is detected by the position sensor 7, and the signal is transmitted to the controller. The controller adjusts the action of the driving member according to the set grinding quality parameters, so that the trigger block 12 remains in the trigger area or leaves the trigger pre-area, thereby realizing the adjustment of the feeding times of the grinding wheel 4. In this way, the grinding quality of the blade can be guaranteed, and then the quality of the cut tobacco can be guaranteed. In this embodiment, the controller adopts a PLC control system, and its own control panel can display relevant parameters, such as the frequency of the left reciprocating motion of the sliding bracket 2, the current feeding times of the grinding wheel 4, etc.

[0031] The driving member includes a telescopic member 8, which is fixedly mounted on the frame 1 by bolts. In this embodiment, the telescopic member 8 adopts a cylinder, which can be directly connected to the air source of the wire cutting machine equipment, without the need to set up additional circuits, etc., with a simple structure and easy installation. The telescopic end of the telescopic member 8 is fixedly connected to the trigger block 12, and the trigger block 12 is tilted. The trigger block 12 tilts from the outer end to the inner end toward the sliding bracket 2, and the trigger block 12 tilts from bottom to top toward the sliding bracket 2. In this embodiment, an inclined surface in contact with the free end of the swing arm mechanism is arranged on the outer side of the trigger block 12, and the telescopic member 8 is arranged vertically. Since the sliding bracket 2 of the SQ series wire cutting machine is tilted on the frame 1, the swing arm mechanism is usually also tilted. Through the tilted trigger block 12, it can be well matched with the swing arm mechanism. Among them, the end of the trigger block 12 close to the frame 1 is the inner end, and the end away from the frame 1 is the outer end.

[0032] A connecting block 11 is provided between the trigger block 12 and the telescopic member 8. One end of the connecting block 11 is fixedly connected to the telescopic end of the telescopic member 8, and the other end is provided with an angle adjustment component. The trigger block 12 is slidably hinged with the angle adjustment component, and the angle adjustment component is used to adjust the tilt angle of the trigger block 12. Two angle adjustment components are provided along the length direction of the trigger block 12, and an adjustment rod 28 is provided between each angle adjustment component and the trigger block 12. The outer wall of the trigger block 12 facing the angle adjustment component is provided with a slide groove 27 corresponding to the two adjustment rods 28. The slide groove 27 extends along the length direction of the trigger block 12. One end of the adjustment rod 28 is inserted into the corresponding slide groove 27 and the two are slidably hinged, and the other end is movably connected to the angle adjustment component. The angle adjustment assembly includes a first motor 13 and a rotating cylinder 14. The rotating cylinder 14 is rotatably mounted on the connecting block 11 through a bearing. A through hole is axially penetrated through the rotating cylinder 14. An internal thread is arranged on the side wall of the through hole of the rotating cylinder 14. A worm gear 15 is fixedly sleeved on the outer wall of the rotating cylinder 14. The first motor 13 is fixedly mounted on the connecting block 11 by bolts. A worm 16 meshing with the worm gear 15 is fixedly mounted on the output end of the first motor 13. An external thread is arranged on the surface of the adjusting rod 28. The end of the adjusting rod 28 away from the trigger block 12 is inserted into the rotating cylinder 14 and the two are threadedly matched. The adjusting rod 28 cannot rotate in the rotating cylinder 14. In this embodiment, a limiting rod 17 with a regular pentagonal cross-section is fixed to the connecting block 11, the axis of the limiting rod 17 is colinear with the axis of the rotating cylinder 14, the free end of the limiting rod 17 extends into the through hole of the rotating cylinder 14, and the end face of the adjusting rod 28 is provided with a limiting hole matching the limiting rod 17. When the adjusting rod 28 is inserted into the through hole, the limiting rod 17 is also inserted into the limiting hole. Such a structural design is simple in structure and easy to install. Under the limiting action of the limiting rod 17, the adjusting rod 28 cannot rotate.

[0033] In this embodiment, the adjusting rod 28 is ball-jointed with the trigger block 12, and the first motor 13 rotates to drive the worm 16 to rotate, and the worm 16 drives the worm wheel 15 and the rotating cylinder 14 to rotate. Under the action of the limit rod 17, the adjusting rod 28 makes a linear motion along the axis of the rotating cylinder 14. By designing two adjustment components, the inclination angle of the inclined surface of the trigger block 12 can be adjusted. Such a structural design can adjust the feed amount of the grinding wheel 4 each time according to actual conditions. It has a simple structure, is easy to install, and is highly practical.

[0034] The frame 1 is provided with a guide assembly below the telescopic end of the telescopic member 8, and the guide assembly includes a guide frame 9 and a transmission block. The guide frame 9 is provided with a guide channel along the axial direction (i.e., vertical direction) of the telescopic member 8, and the transmission block is slidably installed in the guide channel. The top of the guide block 10 is fixedly connected to the telescopic end of the telescopic member 8, and the bottom is fixedly connected to the connecting block 11. Such a structural design makes it difficult for the telescopic member 8 to deviate when driving the connecting block 11 and the trigger block 12 to rise and fall in the vertical direction.

[0035] A grinding wheel 4 and a second motor 3 are provided on the sliding bracket 2, and the grinding wheel 4 is driven to rotate by the second motor 3. A screw rod 20 is rotatably installed on the sliding bracket 2, and a guide rod 21 is fixedly installed. The axis of the guide rod 21 is parallel to the axis of the screw rod 20. A mounting frame 5 is fixedly sleeved on the outer wall of the second motor 3. The mounting frame 5 is slidably matched with the sliding bracket 2. The mounting frame 5 is provided with a threaded hole for the screw rod 20 to pass through, and a through hole for the guide rod 21 to pass through. The screw rod 20 is driven by a swing arm mechanism so that the screw rod 20 can only rotate in one direction.

[0036] The swing arm mechanism includes a transmission swing arm 18 and a mounting shell 23. A ratchet 22 is fixedly sleeved on the screw rod 20. The mounting shell 23 is rotatably sleeved on the screw rod 20. A mounting groove 30 is provided on the mounting shell 23. The ratchet 22 is located in the mounting groove 30. A pawl 24 for engaging with the ratchet 22 is rotatably mounted on the inner side wall of the mounting shell 23. A first spring 25 is arranged between the pawl 24 and the mounting shell 23. The two ends of the first spring 25 are respectively fixedly connected to the side wall of the pawl 24 and the inner side wall of the mounting shell 23. The first spring 25 makes the pawl 24 always have a tendency to maintain engagement with the ratchet 22. One end of the transmission swing arm 18 is fixedly connected to the outer side wall of the mounting shell 23, and the other end extends out of the sliding bracket 2 to form a suspended end. In this embodiment, a roller 19 is rotatably mounted on the free end of the transmission swing arm 18. The roller 19 is used to roll in contact with the inclined surface of the trigger block 12.

[0037] A second spring 26 is provided between the suspended end of the transmission swing arm 18 and the sliding bracket 2 , and two ends of the second spring 26 are fixedly connected to the sliding bracket 2 and the transmission swing arm 18 , respectively.

[0038] In the above embodiment, when the roller 19 on the transmission swing arm 18 of the sliding bracket 2 moves to the left and contacts the trigger block 12, under the guiding action of the inclined surface of the trigger block 12, the roller 19 drives the transmission swing arm 18 to swing outward, thereby driving the mounting shell 23 to rotate counterclockwise. When the mounting shell 23 rotates counterclockwise, the pawl 24 abuts against the teeth of the ratchet wheel 22, and the pawl 24 drives the ratchet wheel 22 to rotate counterclockwise synchronously, thereby causing the screw rod 20 to rotate counterclockwise, and finally the mounting frame 5, the second motor 3 and the grinding wheel 4 complete the feeding; when the sliding bracket 2 moves to the right, the transmission swing arm 18 is reset under the action of the second spring 26, and at this time the transmission swing arm 18 swings inward, and the mounting shell 23 and the pawl 24 rotate clockwise to reset, while the ratchet wheel 22 and the screw rod 20 do not rotate.

[0039] Under the synergistic effect of the above components, the device can achieve precise control and automatic operation of the grinding wheel 4. When the PLC control program is started, the telescopic member 8 reciprocates rhythmically according to the parameters set by the program, drives the trigger block 12 to move, and then pushes the grinding wheel 4 to perform cutting or grinding operations. The counter 6 counts the number of reciprocating times of the trigger block 12 in real time. Through the preset counting threshold, the movement frequency of the telescopic member 8 can be automatically adjusted to ensure that the feed speed of the grinding wheel 4 is constant and the processing quality is improved. The position sensor 7 plays an important monitoring role. It continuously detects the current position of the grinding wheel 4 and feeds the data back to the PLC control program. By comparing with the preset position parameters, the PLC can determine whether the grinding wheel 4 has reached the target position. If it has not reached, the movement direction and speed of the telescopic member 8 are adjusted to ensure that the grinding wheel 4 moves according to the predetermined trajectory; if it has reached, the feeding is stopped or the next action is triggered, such as switching the grinding wheel 4 or starting the cooling system. The entire system has achieved a high degree of automation and intelligence through carefully designed control logic, greatly improving production efficiency and processing accuracy, while also reducing labor intensity and production costs.

[0040] The working principle is as follows: when the blade begins to wear, the position sensor 7 detects the position of the grinding wheel 4 and transmits the signal to the PLC control program. The PLC control program adjusts the action of the telescopic member 8 according to the set grinding quality parameters, so that the trigger block 12 moves accordingly, thereby adjusting the feeding times of the grinding wheel 4. In this way, the grinding quality of the blade can be guaranteed, and then the quality of the cut tobacco can be guaranteed.

[0041] The advantages of the present invention mainly include the following points: (1) The feeding times of the grinding wheel 4 can be adjusted according to the wear of the blade, thereby improving the grinding quality of the blade.

[0042] (2) The consumption of the grinding wheel 4 is reduced, and the service life of the grinding wheel 4 is extended.

[0043] (3) The production efficiency of the tobacco cutter is improved and the quality of the tobacco is ensured.

[0044] (4) Simple structure, easy to install and maintain.
