A rubber production apparatus strip cutting device

Abstract

This utility model discloses a rubber strip cutting device belonging to the field of rubber production technology. It includes a cutter holder, a feeding mechanism, and a cutting mechanism. The feeding mechanism guides the rubber strip into the cutting mechanism. The key feature is that a carrying plate is located behind the cutting mechanism, and several positioning pins are inserted through the carrying plate. The rubber strip passes through the cutting mechanism, and the positioning pins on the carrying plate penetrate the end of the rubber strip. Then, the cutting mechanism cuts out a fixed quantity of rubber strips. When the end of the rubber strip moves to the cutting mechanism, the positioning pins can penetrate the end of the rubber strip during the cutting process, preventing the cut rubber strip from shifting or retracting. This ensures that each rubber strip is of consistent length and has a flat cut surface, achieving quantitative cutting of the rubber strip. Furthermore, the positioning pins can stably hold the cut rubber strip, facilitating accurate gripping and transfer by a subsequent robotic arm or conveying device, achieving efficient continuity and stability from cutting to transfer.

Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, and specifically to a strip cutting device for rubber production equipment. Background Technology

[0002] Before vulcanization, the rubber needs to be cut into strips. After the rubber raw material is heated and extruded, it is formed into rubber strips. The rubber strips are then cut into strips of the corresponding length by a strip cutting device, and then the strips are transferred to the vulcanization equipment for vulcanization molding.

[0003] Chinese utility model patent publication number "CN221497019U" discloses an automated rubber strip cutting device, including a control system and a frame. Within the frame, a rubber extrusion mechanism, an auxiliary mechanism, a rubber production equipment cutting device, and a conveyor belt mechanism are arranged sequentially. A die is located at the outlet of the rubber extrusion mechanism. The auxiliary mechanism includes a connecting plate, a tensioning wheel, and an auxiliary wheel. The rubber production equipment cutting device includes a moving belt, a pressure cylinder device, and a cutting knife device. A roller device is located in front of the cutting device, and a moving mechanism is located on one side of the moving belt. A feeding robot mechanism is installed on the conveyor belt mechanism. Under the control of the control system, the rubber extrusion mechanism, the auxiliary mechanism, the rubber production equipment cutting device, the conveyor belt mechanism, and the die cooperate to automate rubber strip feeding, equal-quantity cutting, and loading.

[0004] However, when the rubber cutting device in the aforementioned automated rubber cutting equipment cuts rubber strips, the rubber strips cut by the cutter are prone to deviation. During transfer, they cannot be accurately placed on the transfer platform, resulting in defects and uneven thickness in the vulcanized products, and a high defect rate of rubber products.

[0005] Furthermore, during the up-and-down movement of the cutter, the movement of the cutter and the rubber strip is prone to deviation, which makes it impossible to guarantee the quality of the cut rubber strip. Ultimately, this leads to inconsistent quality of the vulcanized rubber products, failing to meet product consistency requirements.

[0006] Therefore, it is necessary to improve upon the aforementioned shortcomings. Utility Model Content

[0007] The purpose of this invention is to provide a strip-cutting device for rubber production equipment that provides quantitative strip cutting and stable transfer, so as to solve the above-mentioned problems existing in the prior art.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a strip cutting device for rubber production equipment, including a cutter holder, a feeding mechanism, and a cutting mechanism. The feeding mechanism is used to guide the rubber strip into the cutting mechanism. The feature is that a material carrier plate is provided behind the cutting mechanism, and a plurality of positioning pins are provided on the material carrier plate. The rubber strip passes through the cutting mechanism and the positioning pins on the material carrier plate are inserted into the end of the rubber strip. Then the cutting mechanism cuts out a certain amount of rubber strips.

[0009] By adopting the above technical solution: when the end of the rubber strip moves to the cutting mechanism, the positioning pin can penetrate the end of the rubber strip during the cutting process, which can prevent the cut rubber strip from shifting or retracting, thereby ensuring that each rubber strip is of consistent length and has a flat cut surface, realizing quantitative cutting of the rubber strip. In addition, the positioning pin can stably clamp the cut rubber strip, which is convenient for subsequent robotic arms or conveying devices to accurately grasp and transfer, achieving efficient continuity and stability from cutting to transfer.

[0010] The cutting device of the aforementioned rubber production equipment can be further configured as follows: the cutter holder is provided with a guide slide rail, the guide slide rail is provided with a guide slider, a fixed plate is provided below the material carrier plate, the fixed plate is linked with the guide slider, a mounting support plate is provided in the middle of the fixed plate, the cutter holder is provided with a push plate cylinder, the body of the push plate cylinder is fixedly connected to the cutter holder, and the output end is fixedly connected to the mounting support plate.

[0011] By adopting the above technical solution: when the cut rubber strip is fixed on the carrier plate by the positioning pin, the push plate cylinder can drive the mounting plate and fixing plate to slide precisely along the guide rail, thereby driving the carrier plate to move smoothly. The cooperation between the guide rail and the guide slider effectively restricts the degree of freedom of movement, ensuring that the carrier plate always maintains linear motion and stable posture when approaching and leaving the cutting station, avoiding secondary displacement or deformation of the rubber strip after cutting, and greatly improving the continuity and accuracy of quantitative cutting and subsequent gripping and transfer.

[0012] The cutting device of the aforementioned rubber production equipment can be further configured as follows: the cutting mechanism includes a mounting plate, a cutting blade mounted on the mounting plate, a cutting blade cylinder mounted on the cutting blade holder, a mounting groove on the mounting plate, the body of the cutting blade cylinder being fixedly connected to the cutting blade holder, and the output end passing through the mounting groove, and the operation of the cutting blade cylinder driving the mounting plate to move axially.

[0013] By adopting the above technical solution: the output end of the cutter cylinder is inserted into the mounting groove of the mounting plate. When the cutter cylinder is running, it can drive the mounting plate to move along the axis of the cutter cylinder, thereby driving the cutter to cut the rubber strip. The structure is compact, the movement is stable, and the cutting smoothness and cut quality are improved.

[0014] The cutting device of the rubber production equipment described above can be further configured as follows: the cutting blade holder is vertically provided with a cutting blade slide rail, the cutting blade slide rail is slidably fitted with a cutting blade slider, the cutting blade slider is linked with the mounting plate, the mounting plate is provided with a pressing component above the material carrier plate, the pressing component is linked with the mounting plate, the pressing component can squeeze the rubber strip, causing the positioning pin to penetrate into the rubber strip.

[0015] By adopting the above technical solution, the sliding cooperation between the cutter slider and the cutter rail provides precise guidance for the vertical movement of the mounting plate and the pressure component, ensuring the stability of the pressure component during the pressing process. In addition, the pressure component moves down synchronously with the mounting plate, and can contact and press the rubber strip before the cutter cuts, so that it is close to the surface of the carrier plate. This ensures that the positioning pin can smoothly and accurately penetrate the end of the rubber strip, effectively preventing the rubber strip from sliding or lifting during piercing and cutting, and further ensuring the dimensional accuracy of the quantitative cut strip and the reliability of subsequent transportation.

[0016] The cutting device of the aforementioned rubber production equipment can be further configured as follows: the pressing component includes a pressing plate and a connecting plate, the pressing plate and the connecting plate are L-shaped, the connecting plate has a plurality of first connecting grooves, the mounting plate has a plurality of second connecting grooves, the cutter has a plurality of connecting holes, the connecting holes, the first connecting grooves and the second connecting grooves are correspondingly arranged, and connecting bolts are inserted into the connecting holes, the first connecting grooves and the second connecting grooves to realize the detachable connection between the cutter plate, the pressing component and the mounting plate.

[0017] By adopting the above technical solution: the pressure plate is detachably connected to the mounting plate through the connecting plate. The pressure plate and the connecting plate are L-shaped. When the connecting plate and the mounting plate move synchronously, the pressure plate can contact the upper surface of the rubber strip, thereby pressing the rubber strip onto the carrier plate. The positioning pin is inserted into the rubber strip to prevent the rubber strip from shifting during the cutting process and improve the stability of the rubber strip during the cutting process.

[0018] The cutting device of the aforementioned rubber production equipment can be further configured as follows: the cutting blade holder is also provided with a transfer component, the transfer component includes a rodless cylinder, a first pushing cylinder, a second pushing cylinder, and a third pushing cylinder. The rodless cylinder is provided with a first slider, the first pushing cylinder is linked with the first slider, the body of the first pushing cylinder is provided with a second slider, the second slider is slidably fitted with a first slide rail, the output end of the first pushing cylinder is provided with a first pushing plate, the first slide rail is linked with the first pushing plate, the first pushing plate is connected to a second pushing plate, the end of the second pushing plate is provided with a second pushing cylinder, the output end of the second pushing cylinder is provided with a third pushing plate, the third pushing cylinder is fixedly connected to the third pushing plate, and the output end of the third pushing cylinder is provided with a transfer needle plate.

[0019] By adopting the above technical solution: after the rubber strip is cut into rubber strips, the transfer component can transfer the rubber strip to the subsequent work station. During the transfer, the rodless cylinder drives the first slider to move, and the first pusher cylinder moves synchronously with the first slider. During the movement of the first slider, the first pusher cylinder can push the first pusher plate to move, which drives the second pusher cylinder to move along the axis of the first pusher cylinder. When the first pusher cylinder pushes the first pusher plate to move, the first slide rail moves synchronously with the first pusher plate. The first slide rail slides relative to the first slider, which improves the stability of the first pusher plate during movement. At the same time, the second pusher cylinder pushes the second pusher plate to move, causing the third pusher cylinder to move downward. When the third pusher cylinder moves above the cutting platform, the third pusher cylinder operates to insert the transfer needle at the end of the transfer needle plate into the rubber strip, realizing the precise gripping, lifting and transfer of the rubber strip in three-dimensional space. The automation level is high and the action is smooth and stable.

[0020] The cutting device of the rubber production equipment described above can be further configured such that: a transfer plate is provided at the end of the third pusher plate, and the transfer plate has a number of needle grooves that cooperate with the transfer needle plate, and the needles at the end of the transfer needle plate can pass through the needle grooves and penetrate into the rubber strip.

[0021] By adopting the above technical solution: when the third pushing cylinder pushes the transfer needle plate to move, the transfer needle at the end of the transfer needle plate passes through the needle groove of the transfer plate and then inserts into the rubber strip. When the transfer component transfers the rubber strip to the next station, the third pushing cylinder retracts, the rubber strip is blocked by the transfer plate, the transfer needle plate slides relative to the rubber strip, and then the rubber strip separates from the transfer needle plate and falls naturally to the next station, completing the quick transfer of the rubber strip.

[0022] The cutting device of the rubber production equipment described above can be further configured as follows: the feeding mechanism includes several support rollers rotatably mounted on the cutting frame and a feeding roller for driving the rubber strip to move. The cutting frame is equipped with a servo motor, and the feeding roller is linked to the output end of the servo motor.

[0023] By adopting the above technical solution: the rubber strip moves from the support roller shaft to the feed roller shaft, and the servo motor drives the feed roller shaft to rotate, which can accurately control the moving length of the rubber strip and accurately control the width of the rubber strip cut by the cutting mechanism, thereby realizing quantitative cutting of the rubber strip. The support roller shaft can improve the stability of the rubber strip during feeding.

[0024] The cutting device of the aforementioned rubber production equipment can be further configured as follows: the cutting frame is provided with several feeding slides above the support roller shaft, the feeding slides are slidably fitted with a first limiting support plate and a second limiting support plate, the feeding slides are also slidably fitted with a mounting slide plate, a feeding cylinder is fixed on the mounting slide plate, and the first limiting support plate is linked with the output end of the feeding cylinder.

[0025] By adopting the above technical solution: the feeding cylinder can drive the first limiting support plate to slide precisely along the feeding slide bar, thereby flexibly adjusting the distance between the first and second limiting support plates to accommodate rubber strips of different widths. Combined with the servo motor, the width and length of the cut rubber strips can be adjusted, thereby changing the volume of the rubber strips to meet the production needs of different rubber products. At the same time, the adjustable guide and limiting channels effectively prevent deviation or lateral sliding during the conveying process, ensuring that the rubber strips always enter the cutting mechanism smoothly in a straight line, further improving the accuracy of quantitative strip cutting and the stability of the entire production process.

[0026] The cutting device of the above-mentioned rubber production equipment can be further configured as follows: the cutting frame is equipped with a pressing cylinder, the body of the pressing cylinder is detachably connected to the cutting frame, the output end is equipped with a pressing block, a pressing roller shaft is provided above the feeding roller shaft, and the pressing roller shaft and the pressing block are rotatably engaged and linked with the pressing block.

[0027] By adopting the above technical solution, the pressing cylinder can drive the pressing block and the pressing roller linked with it to move downward, thereby stably pressing the rubber strip onto the feeding roller shaft to form a reliable clamping force. This structure effectively prevents relative sliding or slippage between the rubber strip and the roller shaft during the feeding process, ensuring that the feeding length controlled by the servo motor can be accurately converted into the actual feed amount of the rubber strip, eliminating the length error caused by slippage, and providing a crucial length guarantee for subsequent quantitative cutting.

[0028] The beneficial effects of this utility model are as follows: By setting positioning pins on the carrier plate, the rubber strip cutting mechanism allows the positioning pins to penetrate the rubber strip end during cutting. Compared with the traditional method of directly cutting the rubber strip with a cutter, the rubber strip of this utility model has higher stability during cutting. At the same time, the transfer component can move the rubber strip on the carrier plate in three dimensions, thereby placing the rubber strip at a designated position in the next work station, achieving efficient transfer of the rubber strip.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] A strip cutting device for rubber production equipment, such as Figures 1 to 6 As shown, the device includes a cutter holder 1, a feeding mechanism 2, and a cutting mechanism 3. The feeding mechanism 2 guides the rubber strip into the cutting mechanism 3. The key feature is that a material carrier plate 4 is located behind the cutting mechanism 3, and several positioning pins 41 are threaded through the material carrier plate 4. The rubber strip passes through the cutting mechanism 3, and the positioning pins 41 on the material carrier plate 4 penetrate the end of the rubber strip. Then, the cutting mechanism 3 cuts out a fixed quantity of rubber strips. When the end of the rubber strip moves to the cutting mechanism 3, the positioning pins 41 can penetrate the end of the rubber strip during the cutting process, preventing the cut rubber strip from shifting or retracting. This ensures that each rubber strip has a consistent length and a flat cut surface, achieving quantitative cutting of the rubber strip. Furthermore, the positioning pins 41 can stably hold the cut rubber strip, facilitating accurate gripping and transfer by a subsequent robotic arm or conveying device, achieving efficient continuity and stability from cutting to transfer.

[0033] like Figure 3As shown, the feeding mechanism 2 includes several support rollers 21 rotatably mounted on the cutter holder 1 and a feeding roller 22 for driving the movement of the rubber strip. The cutter holder 1 is equipped with a servo motor 23, and the feeding roller 22 is linked to the output end of the servo motor 23. The rubber strip moves from the support rollers 21 to the feeding roller 22, and the servo motor 23 drives the feeding roller 22 to rotate, which can precisely control the moving length of the rubber strip and the width of the rubber strip cut by the cutter mechanism 3, thereby achieving quantitative cutting of the rubber strip. The support rollers 21 can improve the stability of the rubber strip during feeding.

[0034] The cutter holder 1 is equipped with several feeding slide rods 24 above the support roller shaft 21. Each feeding slide rod 24 is slidably fitted with a first limiting support plate 241 and a second limiting support plate 242. The feeding slide rod 24 is also slidably fitted with a mounting slide plate 243, on which a feeding cylinder 25 is fixed. The first limiting support plate 241 is linked to the output end of the feeding cylinder 25. The feeding cylinder 25 can drive the first limiting support plate 241 to slide precisely along the feeding slide rods 24, thereby flexibly adjusting the distance between the first limiting support plate 241 and the second limiting support plate 242 to accommodate rubber strips of different widths. Combined with the servo motor 23, the width and length of the cut rubber strip can be adjusted, thus changing the volume of the rubber strip to meet the production needs of different rubber products. Simultaneously, the adjustable guide and limiting channels effectively prevent deviation or lateral sliding during the conveying process, ensuring that the rubber strip always enters the cutter mechanism 3 smoothly in a straight line, further improving the accuracy of quantitative cutting and the stability of the entire production process.

[0035] The cutter holder 1 is equipped with a pressing cylinder 26. The body of the pressing cylinder 26 is detachably connected to the cutter holder 1, and a pressing block 27 is provided at the output end. A pressing roller shaft 28 is provided above the feeding roller shaft 22. The pressing roller shaft 28 rotates and engages with the pressing block 27 and is linked with the pressing block 27. The pressing cylinder 26 can drive the pressing block 27 and the pressing roller shaft 28 linked with it to move downward, thereby stably pressing the rubber strip onto the feeding roller shaft 22 to form a reliable clamping force. This structure effectively prevents relative sliding or slippage between the rubber strip and the roller shaft during the feeding process, ensuring that the feeding length controlled by the servo motor 23 can be accurately converted into the actual feed amount of the rubber strip, eliminating the length error caused by slippage, and providing a crucial length guarantee for subsequent quantitative cutting.

[0036] like Figure 4 , Figure 5As shown, the cutting mechanism 3 includes a mounting plate 31, a cutter 32 mounted on the mounting plate 31, and a cutter cylinder 33 mounted on the cutter holder 1. The mounting plate 31 has a mounting groove 311. The body of the cutter cylinder 33 is fixedly connected to the cutter holder 1, and its output end passes through the mounting groove 311. The operation of the cutter cylinder 33 drives the mounting plate 31 to move axially. The output end of the cutter cylinder 33 is engaged in the mounting groove 311 of the mounting plate 31. When the cutter cylinder 33 operates, it can drive the mounting plate 31 to move axially along the cutter cylinder 33, thereby driving the cutter 32 to cut the rubber strip. The structure is compact, the movement is stable, and the cutting smoothness and cut quality are improved.

[0037] The cutter holder 1 is vertically equipped with a cutter slide rail 13, and a cutter slider 14 is slidably engaged with the cutter slide rail 13. The cutter slider 14 is linked with the mounting plate 31. The mounting plate 31 is equipped with a pressing component 34 above the material carrier plate 4. The pressing component 34 is linked with the mounting plate 31. The sliding engagement between the cutter slider 14 and the cutter slide rail 13 provides precise guidance for the vertical movement of the mounting plate 31 and the pressing component 34, ensuring the stability of the pressing component 34 during the pressing process. In addition, the pressing component 34 moves down synchronously with the mounting plate 31, and can contact and press the rubber strip before the cutter 32 cuts, so that it is close to the surface of the material carrier plate 4. This ensures that the positioning needle 41 can smoothly and accurately penetrate the end of the rubber strip, effectively preventing the rubber strip from sliding or lifting during piercing and cutting, and further ensuring the dimensional accuracy of the quantitative cut strip and the reliability of subsequent transfer.

[0038] The pressing component 34 includes a pressing plate 341 and a connecting plate 342. The pressing plate 341 and the connecting plate 342 are L-shaped. The connecting plate 342 has a plurality of first connecting grooves 343. The mounting plate 31 has a plurality of second connecting grooves 312. The cutter 32 has a plurality of connecting holes 321. The connecting holes 321, the first connecting grooves 343, and the second connecting grooves 312 are correspondingly arranged. Connecting bolts are inserted into the connecting holes 321, the first connecting grooves 343, and the second connecting grooves 312 to achieve a detachable connection between the cutter 32, the pressing component 34, and the mounting plate 31. The pressing component 34 is detachably connected to the mounting plate 31 via the connecting plate 342. The pressing plate 341 and the connecting plate 342 are L-shaped. When the connecting plate 342 and the mounting plate 31 move synchronously, the pressing plate 341 can contact the upper surface of the rubber strip, thereby pressing the rubber strip onto the carrier plate 4. The positioning pin 41 is inserted into the rubber strip to prevent the rubber strip from shifting during the cutting process and to improve the stability of the rubber strip during the cutting process.

[0039] The cutter holder 1 is equipped with a guide rail 11, and a guide slider 12 is mounted on the guide rail 11. A fixing plate 42 is located below the material carrier plate 4. The fixing plate 42 is linked with the guide slider 12. A mounting support plate 43 is located in the middle of the fixing plate 42. The cutter holder 1 is equipped with a push plate cylinder 44. The body of the push plate cylinder 44 is fixedly connected to the cutter holder 1, and its output end is fixedly connected to the mounting support plate 43. When the cut rubber strip is fixed on the material carrier plate 4 by the positioning pin 41, the push plate cylinder 44 can drive the mounting support plate 43 and the fixing plate 42 to slide precisely along the guide rail 11, thereby driving the material carrier plate 4 to move smoothly. The cooperation between the guide rail 11 and the guide slider 12 effectively restricts the degree of freedom of movement, ensuring that the material carrier plate 4 always maintains linear motion and stable posture during the process of approaching and leaving the cutter station, avoiding secondary displacement or deformation of the rubber strip after cutting, and greatly improving the continuity and accuracy of quantitative cutting and subsequent gripping and transfer.

[0040] like Figure 6 , Figure 7 As shown, the cutter holder 1 is also equipped with a transfer assembly 5, which includes a rodless cylinder 51, a first pusher cylinder 52, a second pusher cylinder 53, and a third pusher cylinder 54. The rodless cylinder 51 is equipped with a first slider 511, and the first pusher cylinder 52 is linked with the first slider 511. The body of the first pusher cylinder 52 is equipped with a second slider 521, and the second slider 521 is slidably engaged with a first slide rail 522. The output end of the first pusher cylinder 52 is equipped with a first pusher plate 523, and the first slide rail 522 is linked with the first pusher plate 523. The first pusher plate 523 is connected to a second pusher plate 524, and the end of the second pusher plate 524 is equipped with a second pusher cylinder 53. The output end of the second pusher cylinder 53 is equipped with a third pusher plate 531, and the third pusher cylinder 54 is fixedly connected to the third pusher plate 531. The output end of the third pusher cylinder 54 is equipped with a transfer needle plate 55. After the rubber strips are cut from the long strips, the transfer assembly 5 can transfer the rubber strips to the subsequent workstation. During the transfer, the rodless cylinder 51 drives the first slider 511 to move, and the first pusher cylinder 52 moves synchronously with the first slider 511. During the movement of the first slider 511, the first pusher cylinder 52 can push the first pusher plate 523 to move, driving the second pusher cylinder 53 to move along the axial direction of the first pusher cylinder 52. When the first pusher cylinder 52 pushes the first pusher plate 523 to move, the first slide rail 522 and the first pusher... The plate 523 moves synchronously, and the first slide rail 522 slides relative to the first slider 511, which improves the stability of the first transfer plate when it moves. At the same time, the second pusher cylinder 53 pushes the second pusher plate 524 to move, causing the third pusher cylinder 54 to move downward. When the third pusher cylinder 54 moves above the cutting platform, the third pusher cylinder 54 operates to insert the transfer needle at the end of the transfer needle plate 55 into the rubber strip, realizing the precise gripping, lifting and transfer of the rubber strip in three-dimensional space. The degree of automation is high and the action is smooth and stable.

[0041] The end of the third pusher plate 531 is provided with a transfer plate 541. The transfer plate 541 has several needle grooves 542 that cooperate with the transfer needle plate 55. When the third pusher cylinder 54 pushes the transfer needle plate 55 to move, the transfer needle at the end of the transfer needle plate 55 passes through the needle grooves 542 of the transfer plate 541 and then inserts into the rubber strip. When the transfer component 5 transfers the rubber strip to the next station, the third pusher cylinder 54 retracts, the rubber strip is held by the transfer plate 541, the transfer needle plate 55 slides relative to the rubber strip, and then the rubber strip separates from the transfer needle plate 55 and falls naturally to the next station, completing the quick transfer of the rubber strip.

[0042] The working principle of this embodiment is as follows: The rubber strip is first guided by the support roller 21 into the feed roller 22 driven by the servo motor 23. By precisely controlling the rotation angle of the feed roller 22, fixed-length feeding can be achieved. During the feeding process, the adjustable-width channel formed by the first limiting support plate 241 and the second limiting support plate 242 prevents the rubber strip from deviating. The pressing cylinder 26 drives the pressing roller 28 to press down, which works in conjunction with the feed roller 22 to clamp the rubber strip.

[0043] When the front end of the rubber strip is delivered to the cutting station, the cutting cylinder 33 drives the mounting plate 31 to move down, which in turn causes the pressing component 34 to press the rubber strip tightly against the carrier plate 4. Then, the positioning pin 41 precisely inserts into the end of the rubber strip to fix it, and the cutting blade 32 continues to move down to complete the cutting.

[0044] After cutting, the push plate cylinder 44 drives the fixed plate 42 to move along the guide rail 11, and removes the material plate 4 carrying the rubber strip; in the transfer assembly 5, the rodless cylinder 51 drives the first push cylinder 52 to adjust the lateral position, the second push cylinder 53 controls the longitudinal displacement, and the third push cylinder 54 drives the transfer needle plate 55 to pierce the rubber strip and grab it; through the linkage of multiple cylinders, the rubber strip is accurately transferred to the next station in three-dimensional space and reliably released through the transfer plate 541.

[0045] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
