Description

Technical Field

[0001] The present invention relates to the technical field of rubber feeding, and specifically to a feeding structure and a feeding method for a rubber cutting machine. Background Art

[0002] A cutting machine is a rubber processing equipment, and its function is to cut rubber blocks (rubber bales) of natural rubber or synthetic rubber into smaller rubber blocks that are easy to process. However, before and after rubber cutting, it is necessary to convey the unformed rubber and the finished rubber.

[0003] There are the following problems with the existing feeding structure of rubber cutting machines: 1. Since the surface of rubber has a certain viscosity, when the surface roughness of the conveying roller is insufficient, or there is oil stain or water stain, the friction force between the roller and the rubber is insufficient, resulting in the rubber slipping on the roller; 2. Problems such as uneven thickness or uneven joints of the rubber belt itself will cause the rubber to shift to one side during the conveying process; 3. Since rubber has a certain viscosity, some of the cut rubber or the whole rubber will adhere to the cutting knife, affecting subsequent cutting processing. Summary of the Invention

[0004] The present invention aims to provide a feeding structure and a feeding method for a rubber cutting machine to solve the problems raised in the above background art.

[0005] To achieve the above object, the present invention provides the following technical solution: A feeding structure for a rubber cutting machine, including a feeding mechanism for limiting and conveying rubber, and a frame is provided on the feeding mechanism;

[0006] A material removing mechanism for removing excess rubber, and the material removing mechanism is connected to the frame;

[0007] A discharging mechanism for separating the cut rubber, and the discharging mechanism is arranged on the feeding mechanism;

[0008] Among them, the feeding mechanism includes a workbench, the top of the workbench is fixedly connected to the frame, a groove is opened at the bottom of the workbench, and a frame plate is slidably fitted in the groove, and one end of the frame plate away from the workbench is fixedly connected to a servo motor;

[0009] The output end of the servo motor is connected to a gear through a coupling, and a rack is engaged and driven at the bottom of the gear. Among them, the gear rotates and moves along the surface of the rack under the drive of the servo motor.

[0010] Preferably, one end of the gear close to the servo motor is fixedly connected with a bearing ring, and the bottom of the bearing ring is fixedly connected with a fixed folding strip. One end of the fixed folding strip away from the bearing ring is fixedly connected with the servo motor;

[0011] The gear is connected to the inner side of the bearing ring, while the outer side of the bearing ring is connected to the fixed folding strip.

[0012] Preferably, a bent rod is fixedly connected to the top of the outer side of the bearing ring. One end of the bent rod away from the bearing ring is fixedly connected with a pushing plate. The height of the pushing plate is lower than that of the rubber, and it pushes the rubber forward under the drive of the servo motor.

[0013] Preferably, a side frame plate is fixedly connected to the outer side of the frame. A material conveying roller is rotatably installed on one side of the side frame plate away from the frame. The material conveying roller is used for the transmission and processing of the rubber.

[0014] Preferably, a first anti-slip frame is fixedly connected to the outer side of the frame. Inner grooves are formed on both the upper and lower sides of the inner cavity of the first anti-slip frame. A sliding strip is slidably fitted inside the inner groove, and a second anti-slip frame is fixedly connected to the outer side of the sliding strip;

[0015] One end of the second anti-slip frame away from the sliding strip is fixedly connected with a double connecting plate. One end of the double connecting plate away from the second anti-slip frame is fixedly connected with the bent rod;

[0016] The first anti-slip frame, the second anti-slip frame and the double connecting plate are all used for the guiding and traction processing of the rubber.

[0017] Preferably, the material removing mechanism includes a curved surface rod. The outer end surface of the curved surface rod is fixedly connected with the frame. The bottom of the curved surface rod is in contact with the top of the rubber to remove the waste remaining on the top of the rubber. One end of the curved surface rod away from the frame is fixedly connected with a curved surface plate.

[0018] Preferably, a cross-cutting knife is fixedly connected to the bottom of the curved surface plate. The cross-cutting knife is used for cutting off the redundant material on the top of the rubber. A longitudinal cutting knife is fixedly connected to the central part of the top of the cross-cutting knife. The longitudinal cutting knife is used for centrally segmenting the redundant material;

[0019] End inclined rails are fixedly connected to the top of the cross-cutting knife. The number of the end inclined rails is two, and they are used for outward outputting the centrally segmented redundant material. One end of the end inclined rail away from the cross-cutting knife is fixedly connected with a supporting inclined plate. The upper and lower ends of the supporting inclined plate are respectively fixedly connected with the curved surface plate and the cross-cutting knife.

[0020] Preferably, a hydraulic cylinder is fixedly installed on the top of the frame, the output end of the hydraulic cylinder is fixedly connected with a limit sleeve, and a rubber cutting knife is fixedly installed at the bottom of the limit sleeve;

[0021] A fixed shaft is fixedly connected inside the rubber cutting knife, a turning piece is rotatably connected to the outside of the fixed shaft, a resilient strip is extrusion-fitted to the top of the turning piece, the top of the resilient strip is fixedly connected to the rubber cutting knife, a first magnetic block is fixedly connected to the central part of the turning piece, a return spring is fixedly connected to the outside of the turning piece, and the end of the return spring away from the turning piece is fixedly connected to the rubber cutting knife.

[0022] Preferably, the discharging mechanism includes an extension rod, the top end of the extension rod is fixedly connected with the limit sleeve, the bottom end of the extension rod is extrusion-fitted with a top inclined block, the bottom of the top inclined block is fixedly connected with a support sliding rod, and both ends of the support sliding rod are slidably fitted with the top of the side frame plate;

[0023] The bottom of the support sliding rod is fixedly connected with a bottom plate, and a second magnetic block is fixedly connected to the outside of the bottom plate, and an attracting relationship is maintained between the second magnetic block and the first magnetic block.

[0024] A feeding method of a rubber cutting machine includes the following steps:

[0025] Step 1: By starting the servo motor, the gear connected to its output end will move meshingly inward along the rack. A bearing ring is fixedly connected to the outside of the gear, and the top of the bearing ring is connected to the pushing plate through a bent rod. Therefore, the pushing plate is used to push the rubber to be cut forward by the meshing transmission of the gear and the rack;

[0026] Step 2: The outside of the bent rod is connected to the double-link plate. Therefore, when the pushing plate connected to the bent rod pushes the rubber forward, the double-link plate will gradually be received into the inside of the second limit sliding frame, and finally the second limit sliding frame will be received into the first limit sliding frame to limit both ends of the rubber during transportation;

[0027] Step 3: As the pushing plate pushes the rubber forward, the top of the rubber will come into contact with the bottom of the cross-cutting knife. If there is no excess material at the top of the rubber, it will move forward along the bottom of the cross-cutting knife and the curved surface rod in sequence. However, when there is excess material accumulated at the top of the rubber, the cross-cutting knife will directly perform a transverse cutting process on it;

[0028] Step 4: During the process of the rubber cutting knife moving downward to cut the rubber, the distance between the second magnetic block and the first magnetic block will be shortened, resulting in an attractive force between the two. At this time, the turning piece connected to the first magnetic block will deflect outward and push out and separate the cut rubber.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] 1. During the cutting process of the rubber, its two ends are limited throughout the process. In addition, it plays a role in fixing the rubber in a specific position, preventing it from moving or shaking during the cutting process, thereby ensuring the accuracy and consistency of the cutting dimensions and improving the product quality.

[0031] 2. Among them, the pushing plate pushes the rubber forward, and the double-link plate, the second anti-slip frame, and the first anti-slip frame always limit the two ends of the rubber, thus making it more convenient for the operator to place the rubber in the appropriate position and eliminating the need to frequently support or adjust the rubber during the cutting process, making the operation more convenient.

[0032] 3. When there is excess material accumulated on the top of the rubber, the cross-cutting knife will directly perform a horizontal cutting process on it. Thus, when the amount of excess material is small, the cut material will accumulate on the cross-cutting knife. Until the tail end of the rubber passes by and moves away from the cross-cutting knife, the residual material will fall onto the conveying roller along the cross-cutting knife. However, there is a gap between the conveying rollers and their surfaces are smooth. Therefore, the residual material will fall from the bottom of the equipment and be collected.

[0033] 4. The rubber is cut in half by the longitudinal cutting knife, and then the cut rubber will move outwards along the outer inclined rail with a smooth grease coating on its surface until it is discharged from its tail end, so as to prevent large pieces of rubber from falling between the two conveying rollers and causing jamming.

[0034] 5. During the process of the rubber cutting knife moving downward to cut the rubber, the distance between the second magnetic block and the first magnetic block will be shortened, resulting in an attractive force between the two. At this time, the turning piece connected to the first magnetic block will deflect outwards, thus playing a role in pushing and separating the rubber that has been cut but still adheres to the rubber cutting knife by the outward deflection of the turning piece.

[0050] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of non-conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments. It should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0051] Please refer to Figures 1 to 14 , the present invention provides a technical solution: as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it includes a feeding mechanism 1 for limiting and conveying rubber, and a frame 4 is arranged on the feeding mechanism 1;

[0052] a rubber removing mechanism 2 for removing excess rubber, and the rubber removing mechanism 2 is connected to the frame 4;

[0053] a discharging mechanism 3 for separating the cut rubber, and the discharging mechanism 3 is arranged on the feeding mechanism 1;

[0054] A hydraulic cylinder 5 is fixedly installed at the top of the frame 4, the output end of the hydraulic cylinder 5 is fixedly connected with a limit sleeve 6, and a rubber cutting knife 7 is fixedly installed at the bottom of the limit sleeve 6.

[0055] Among them, the feeding mechanism 1 includes a workbench 11, the top of the workbench 11 is fixedly connected to the frame 4, a groove is opened at the bottom of the workbench 11, and a frame plate 12 is slidably fitted in the groove, and one end of the frame plate 12 away from the workbench 11 is fixedly connected with a servo motor 13;

[0056] The output end of the servo motor 13 is connected with a gear 14 through a coupling, and a rack 101 is meshed and driven at the bottom of the gear 14. Among them, under the drive of the servo motor 13, the gear 14 rotates and moves along the surface of the rack 101;

[0057] One end of the gear 14 close to the servo motor 13 is fixedly connected with a bearing ring 15, the bottom of the bearing ring 15 is fixedly connected with a fixed folding strip 16, and one end of the fixed folding strip 16 away from the bearing ring 15 is fixedly connected with the servo motor 13;

[0058] Among them, the gear 14 is connected to the inner side of the bearing ring 15, and the outer side of the bearing ring 15 is connected to the fixed folding strip 16;

[0059] A bent rod 17 is fixedly connected to the top of the outer side of the bearing ring 15. One end of the bent rod 17 away from the bearing ring 15 is fixedly connected to a push plate 18. The height of the push plate 18 is lower than that of the rubber, and it pushes the rubber forward under the drive of the servo motor 13.

[0060] A side frame plate 19 is fixedly connected to the outer side of the frame 4. A feeding roller 10 is rotatably installed on one side of the side frame plate 19 away from the frame 4. The feeding roller 10 is used for the transmission and processing of the rubber.

[0061] A first anti-slip frame 102 is fixedly connected to the outer side of the frame 4. Inner grooves 103 are opened on both the upper and lower sides of the inner cavity of the first anti-slip frame 102. A sliding strip 104 is slidably fitted inside the inner groove 103. A second anti-slip frame 105 is fixedly connected to the outer side of the sliding strip 104. The push plate 18 pushes the rubber forward, and the double-link plate 106, the second anti-slip frame 105 and the first anti-slip frame 102 always limit the two ends of the rubber, so that the operator can more conveniently place the rubber in a suitable position, and during the cutting process, there is no need to frequently support or adjust the rubber, making the operation more convenient.

[0062] One end of the second anti-slip frame 105 away from the sliding strip 104 is fixedly connected to a double-link plate 106. One end of the double-link plate 106 away from the second anti-slip frame 105 is fixedly connected to the bent rod 17. The outer side of the bent rod 17 is connected to the double-link plate 106. Therefore, when the push plate 18 connected to the bent rod 17 pushes the rubber forward, the double-link plate 106 will gradually be received into the second anti-slip frame 105. The second anti-slip frame 105 is a general term and includes multiple anti-slip frames. Finally, when the rubber cutting is coming to an end, the sliding strip 104 connected to the other end of the second anti-slip frame 105 will move inward along the inner groove 103 opened inside the first anti-slip frame 102 until the second anti-slip frame 105 is received into the first anti-slip frame 102, so that during the rubber cutting process, the two ends of the rubber will be limited throughout the process. In addition, it also plays a role in fixing the rubber in a specific position, preventing it from moving or shaking during the cutting process, thus ensuring the accuracy and consistency of the cutting size and improving the product quality.

[0063] The height of the rubber is higher than that of the first anti-slip frame 102. In addition, the end faces of the second anti-slip frame 105, the double-link plate 106 and the first anti-slip frame 102 in contact with the two ends of the rubber are all in a vertical relationship. Only the contact end faces between the first anti-slip frame 102 and the second anti-slip frame 105 and the rubber are provided with inner grooves 103. However, due to the height being lower than that of the rubber, the protruding parts of the grooved parts will still limit the rubber.

[0064] Among them, the first limited-slip frame 102, the second limited-slip frame 105, and the double-link plate 106 are all used for guiding and traction treatment of rubber. By placing the rubber to be cut on the feeding roller 10, and the tail end of the rubber is closely attached to the pushing plate 18, at the same time, both ends of the rubber will be respectively attached to the second limited-slip frame 105 and the double-link plate 106. Then, the servo motor 13 is started, so that the gear 14 connected to its output end will rotate forward. The bottom of the gear 14 is meshed and driven with the rack 101. In addition, a groove is opened at the bottom of the rack 101, and a frame plate 12 is slidably fitted in the groove. The other end of the frame plate 12 is fixedly connected to the servo motor 13. Therefore, the gear 14 will move forward along the rack 101, and the servo motor 13 will move forward together. Here, forward means the direction towards the rubber cutting knife 7. A bearing ring 15 is fixedly connected to the outside of the gear 14, and the gear 14 is connected to the inner ring of the bearing ring 15. The bottom of the outer ring of the bearing ring 15 is connected to the fixed folding strip 16, and the other end of the fixed folding strip 16 is connected to the servo motor 13. Therefore, the outer ring of the bearing ring 15 is fixed. In addition, the top of the outer ring of the bearing ring 15 is connected to the pushing plate 18 through the bending rod 17, so as to play the role of using the meshing transmission of the gear 14 and the rack 101 to let the pushing plate 18 push the rubber to be cut forward for conveying.

[0065] As Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, the material removing mechanism 2 includes a curved surface rod 21. The outer end surface of the curved surface rod 21 is fixedly connected to the frame 4. The bottom of the curved surface rod 21 is in contact with the top of the rubber, so as to remove the waste material remaining on the top of the rubber. One end of the curved surface rod 21 away from the frame 4 is fixedly connected to a curved surface plate 22;

[0066] A cross-cutting knife 23 is fixedly connected to the bottom of the curved surface plate 22. The cross-cutting knife 23 is used for cutting off the excess material on the top of the rubber. A longitudinal cutting knife 24 is fixedly connected to the central part of the top of the cross-cutting knife 23. The longitudinal cutting knife 24 is used for central segmentation of the excess material; As the pushing plate 18 pushes the rubber forward, the top of the rubber will be in contact with the bottom of the cross-cutting knife 23. If there is no excess material on the top of the rubber, it will move forward along the bottom of the cross-cutting knife 23 and the curved surface rod 21 in turn. However, when there is excess material accumulated on the top of the rubber, the cross-cutting knife 23 will directly perform transverse cutting on it. Thus, when the amount of excess material is small, the cut material will accumulate on the cross-cutting knife 23 until the tail end of the rubber passes and moves away from the cross-cutting knife 23, and the residual material will fall onto the feeding roller 10 along the cross-cutting knife 23. However, there is a gap between the feeding rollers 10 and their surfaces are smooth. Therefore, the residual material will fall from the bottom of the equipment and be collected.

[0067] The top of the cross cutter 23 is fixedly connected with end inclined rails 25. The number of the end inclined rails 25 is two, and they are used to output the redundant material after central segmentation outward. One end of the end inclined rail 25 far from the cross cutter 23 is fixedly connected with a support inclined plate 26. The support inclined plate 26 is in an inclined state as a whole, and its upper and lower ends are respectively connected with the curved panel 22 and the cross cutter 23, so as to prevent the rubber block divided into two parts from staying in the gap between the curved panel 22 and the cross cutter 23, and at the same time improve the rubber discharge rate. The upper and lower ends of the support inclined plate 26 are respectively fixedly connected with the curved panel 22 and the cross cutter 23. However, when there is a large amount of redundant material at the top of the rubber and it is transversely cut by the cross cutter 23, the cut rubber is pushed forward by the rubber being cut, so that the cut rubber will continue to move upward along the cross cutter 23 until it contacts the longitudinal cutter 24 and is longitudinally cut into two parts. Then the rubber divided into two parts will respectively fall on the two end inclined rails 25. One end of the end inclined rail 25 close to the center is higher than the other end, and the outer side of the end inclined rail 25 is fixedly connected with the support inclined plate 26. In addition, the surfaces of the end inclined rail 25, the support inclined plate 26 and the cross cutter 23 are all coated with smooth grease. It is not the cutting surface of the cross cutter 23 that is smeared with grease, but the area close to the end inclined rail 25 and the support inclined plate 26, so as to discharge the large rubber blocks divided into two parts outward from both ends of the cross cutter 23, and avoid the large rubber blocks falling between the two conveying rollers 10 and causing jamming.

[0068] Because the rubber is strictly processed before cutting and conveying, the thickness of the rubber during cutting is not much different from the thickness after processing. However, it will still expand slightly due to the temperature difference in the factory, but it will not be cut into a plate-like structure by the cross cutter 23 and the longitudinal cutter 24. At most, it is a sheet-like structure. If a plate-like structure appears, it indicates that the rubber is unqualified, and unqualified rubber cannot appear in the subsequent cutting construction. The sheet-like structure will shrink and bend between the curved panel 22, the support inclined plate 23 and the cross section 23. At the same time, the sheet-like structure does not exist all the time, but exists intermittently. Therefore, the cut sheet-like structure will slide out outward due to the inclined state of the end inclined rail 25 and the lubrication of the grease.

[0069] Such as Figure 11 、 Figure 12 、 Figure 13 and Figure 14As shown, a fixed shaft 71 is fixedly connected inside the rubber cutting knife 7. A turning piece 72 is rotatably connected to the outer side of the fixed shaft 71. A resilient strip 73 is press-fitted to the top of the turning piece 72. The top of the resilient strip 73 is fixedly connected to the rubber cutting knife 7. A first magnetic block 74 is fixedly connected to the central part of the turning piece 72. A return spring 75 is fixedly connected to the outer side of the turning piece 72. One end of the return spring 75 away from the turning piece 72 is fixedly connected to the rubber cutting knife 7;

[0070] The unloading mechanism 3 includes an extension rod 31. The top end of the extension rod 31 is fixedly connected to the limit sleeve 6. A top inclined block 32 is press-fitted to the bottom end of the extension rod 31. A support sliding rod 33 is fixedly connected to the bottom of the top inclined block 32. Both ends of the support sliding rod 33 are slidably fitted to the top of the side frame plate 19;

[0071] A bottom plate 34 is fixedly connected to the bottom of the support sliding rod 33. A second magnetic block 35 is fixedly connected to the outer side of the bottom plate 34. The second magnetic block 35 and the first magnetic block 74 maintain an attractive relationship. When the rubber moves to directly below the rubber cutting knife 7, the hydraulic cylinder 5 is started, so that the limit sleeve 6 connected to its output end will drive the rubber cutting knife 7 to move downward and cut the rubber. An extension rod 31 is fixedly connected to the outer side of the limit sleeve 6. Therefore, the limit sleeve 6 will drive the extension rod 31 to move downward and press the top inclined block 32 downward. The contact surfaces between the extension rod 31 and the top inclined block 32 are all inclined surfaces. In addition, the bottom of the top inclined block 32 is connected to the support sliding rod 33, and the support sliding rod 33 is slidably fitted to the top of the side frame plate 19. Therefore, the support sliding rod 33 will drive the top inclined block 32 to move along the top of the side frame plate 19 towards the rubber cutting knife 7. At the same time, the rubber cutting knife 7 will also move downward to cut the rubber. After the rubber is cut, a magnetic attraction will be generated between the first magnetic block 74 fixedly connected to the outer side of the turning piece 72 and the second magnetic block 35. The second magnetic block 35 is connected to the support sliding rod 33 through the bottom plate 34. Then, the turning piece 72 will deflect outward through the fixed shaft 71 and stretch the return spring 75, so as to play a role in externally pushing and separating the rubber that has been cut but still adheres to the rubber cutting knife 7, so as to avoid the rubber adhering to the rubber cutting knife 7 and affecting subsequent cutting. At the same time, if the adhered rubber adheres to both ends of the rubber cutting knife 7, the rubber cutting knife 7 will be stuck and unable to move.

[0072] When the present invention is in use: First, place the rubber to be cut on the feeding roller 10, and the tail end of the rubber is in close contact with the pushing plate 18. At the same time, both ends of the rubber will be respectively in contact with the second limited-slip frame 105 and the double-link plate 106. Then, start the servo motor 13, so that the gear 14 connected to its output end will rotate forward. The bottom of the gear 14 is engaged with the rack 101 for transmission. In addition, a groove is formed at the bottom of the rack 101, and a frame plate 12 is slidably fitted in the groove. The other end of the frame plate 12 is fixedly connected to the servo motor 13. Therefore, the gear 14 will move forward along the rack 101, and the servo motor 13 will move forward together. A bearing ring 15 is fixedly connected to the outside of the gear 14, and the gear 14 is connected to the inner ring of the bearing ring 15. The bottom of the outer ring of the bearing ring 15 is connected to the fixed folding strip 16, and the other end of the fixed folding strip 16 is connected to the servo motor 13. Therefore, the outer ring of the bearing ring 15 is fixed. In addition, the top of the outer ring of the bearing ring 15 is connected to the pushing plate 18 through the bending rod 17. By using the meshing transmission of the gear 14 and the rack 101, the pushing plate 18 is used to push the rubber to be cut forward for transportation.

[0073] The outside of the bending rod 17 is connected to the double-link plate 106. Therefore, when the pushing plate 18 connected to the bending rod 17 pushes the rubber forward for transportation, the double-link plate 106 will gradually be received into the second limited-slip frame 105. Finally, when the rubber cutting is coming to an end, the slide bar 104 connected to the other end of the second limited-slip frame 105 will move inward along the internal groove 103 formed in the first limited-slip frame 102 until the second limited-slip frame 105 is received into the first limited-slip frame 102 to limit both ends of the rubber during transportation.

[0074] As the pushing plate 18 pushes the rubber forward, the top of the rubber will come into contact with the bottom of the cross-cutting knife 23. If there is no excess material at the top of the rubber, it will move forward along the bottom of the cross-cutting knife 23 and the curved surface rod 21 in sequence. However, when there is excess material accumulating at the top of the rubber, the cross-cutting knife 23 will directly perform a transverse cutting process on it. Thus, when the amount of excess material is small, the cut material will accumulate on the cross-cutting knife 23 until the tail end of the rubber passes by and moves away from the cross-cutting knife 23, and the residual material will fall onto the conveying roller 10 along the cross-cutting knife 23. However, there is a gap between the conveying rollers 10 and their surfaces are smooth. But when there is a large amount of excess material at the top of the rubber and it is transversely cut by the cross-cutting knife 23, the cut rubber is pushed forward by the rubber being cut, causing the cut rubber to continue to move upward along the cross-cutting knife 23 until it contacts the longitudinal cutting knife 24 and is longitudinally cut into two parts. Subsequently, the rubber that is split into two will respectively fall on two end inclined rails 25. The surfaces of the end inclined rails 25 are coated with smooth grease. At this time, the large pieces of rubber that are split into two will be discharged outward from both ends of the cross-cutting knife 23 respectively.

[0075] When the rubber moves directly below the rubber cutting knife 7, the hydraulic cylinder 5 is activated, so that the limit sleeve 6 connected to its output end will drive the rubber cutting knife 7 to move downward and cut the rubber. An extension rod 31 is fixedly connected to the outside of the limit sleeve 6. Therefore, the limit sleeve 6 will drive the extension rod 31 to move downward and exert a downward extrusion on the top inclined block 32. The contact surfaces between the extension rod 31 and the top inclined block 32 are all inclined surfaces. In addition, the bottom of the top inclined block 32 is connected to the support sliding rod 33, and the support sliding rod 33 is slidably fitted on the top of the side frame plate 19. Therefore, the support sliding rod 33 will drive the top inclined block 32 to move along the top of the side frame plate 19 towards the direction of the rubber cutting knife 7. At the same time, the rubber cutting knife 7 will also move downward and cut the rubber. After the rubber is cut, a magnetic attraction will be generated between the first magnetic block 74 fixedly connected to the outside of the flipping piece 72 and the second magnetic block 35. The second magnetic block 35 is connected to the support sliding rod 33 through the bottom plate 34. Then, the flipping piece 72 will deflect outward through the fixed shaft 71 and stretch the return spring 75 to push out and separate the cut rubber outward.

Those of ordinary skill in the art, starting from the above concepts and without creative labor, all kinds of transformations made will fall within the scope of protection of the present invention.
