Description

Technical Field

[0001] The invention belongs to the technical field of rubber strip processing equipment, and in particular relates to a multifunctional multi-station rubber strip punching equipment. Background Art

[0002] Rubber strips, or rubber sealing strips, can be used in railway locomotives, automobiles, airplanes, high-rise buildings and various industrial parts. They are sealing elements that prevent external dust, air, water, etc. from entering the system. Rubber sealing strips mainly use the elasticity of the lips, cavities, flanges and other parts in the main structure and the contact pressure generated by the surface of the assembled coupling parts (glass, metal parts, etc.) to achieve the sealing effect. Among them, the production process of automotive rubber strips usually includes mixed extrusion of rubber and steel strips, vulcanization molding, cooling, plasma treatment, spraying treatment, closing treatment, cutting into strips, and post-processing. Post-processing refers to punching, grooving, cutting to length and other operations after the semi-finished rubber strips are cut into strips, so that the semi-finished rubber strips are formed into finished rubber strips that can adapt to the frame installation environment.

[0003] However, most existing post-processing equipment is separate. That is, semi-finished rubber strips need to undergo punching, grooving, and cut-to-length processes on separate machines. This requires multiple machines, occupies a large area, and results in frequent loading and unloading, heavy labor, and low production efficiency. Therefore, it is necessary to design a multi-station integrated rubber strip processing machine that integrates the punching, grooving, and cut-to-length processes into a single machine, achieving multifunctional processing. Summary of the Invention

[0004] The present invention aims to provide a multifunctional multi-station rubber strip punching device to solve the problem that semi-finished rubber strips need to be processed on different devices, resulting in heavy labor and low production efficiency.

[0005] In order to achieve the above-mentioned purpose, the scheme of the present invention is as follows: a multifunctional multi-station rubber strip punching equipment, comprising a workbench, a lifting plate is provided above the workbench, a trimming tool assembly I, an end tool assembly I, a punching tool assembly and an end tool assembly II are provided on the bottom surface of the lifting plate, a longitudinal movement plate is longitudinally slidably connected to the workbench, a mounting seat I and a mounting seat II are provided on the longitudinal movement plate, the mounting seat I includes a first mounting block I, an intermediate mounting block I and a tail mounting block I, the mounting seat II includes a first mounting block II, an intermediate mounting block II and a tail mounting block II, a trimming tool assembly II is provided on the tail mounting block II, the trimming tool assembly II and the trimming tool assembly I both include a trimming tool, the end tool assembly I and the end tool assembly II both include an end cutting tool and a punching tool, and the end tool assembly I also includes a grooving tool, and the punching tool assembly includes a punching tool;

[0006] The first mounting block I, the middle mounting block I and the tail mounting block I are provided with a placement groove I for the semi-finished rubber strip to be placed and a channel for the punching tool to pass through. The first mounting block I is also provided with a knife groove I for the grooving tool to pass through. The first mounting block II and the middle mounting block II are provided with a placement groove II for the semi-finished rubber strip to be placed. The first mounting block II is also provided with a pressure roller for pressing the semi-finished rubber strip. The tail mounting block II is installed on the workbench for horizontal sliding. The longitudinal movement plate is provided with a notch for the tail mounting block II to slide into. The tail mounting block II is provided with a channel for the semi-finished rubber strip to pass through. The tail mounting block II and the first mounting block II are both provided with a knife groove II for the edge cutting tool to pass through. The knife groove II on the first mounting block II is connected with the placement groove II on the first mounting block II and passes through the first mounting block II. The knife groove II on the tail mounting block II is connected with the channel on the tail mounting block II and passes through the tail mounting block II. The longitudinal movement plate is provided with several blanking openings I.

[0007] The working principle and beneficial effects of this solution are as follows: In this solution, mounting seats I and II on the longitudinally movable plate are used to place semi-finished rubber strips. The holes and knife grooves I designed on mounting seat I can cooperate with punching tools and grooving tools to cut and punch the semi-finished rubber strips placed on mounting seat I. Moreover, the longitudinal length of mounting seat I is fixed, and the end cutting tool is aligned with the two ends of mounting seat I to cut the semi-finished rubber strips on mounting seat I to a fixed length. At the same time, the knife groove II designed on mounting seat II can cooperate with the trimming tool to remove the lip edges of the semi-finished rubber strips placed on mounting seat II after the tail mounting block II slides horizontally into place.

[0008] In summary, in this solution, the lifting plate drives each tool assembly to perform grooving, punching, cutting to length, and lip removal on the semi-finished rubber strip in a single operation. This integration integrates the grooving, punching, cutting to length, and lip removal processes on a single device. Compared to traditional separate processing equipment, this solution reduces the number of devices and the equipment's footprint, reduces worker workload, improves production efficiency, and achieves multifunctionality and multi-station operation. Furthermore, the longitudinal plate slides longitudinally on the workbench, keeping it away from the tool assemblies during loading and unloading, enhancing safety.

[0009] Optionally, the end tool assembly I, the punching tool assembly and the end tool assembly II all further include a tool mounting plate I and a floating plate I, the edge trimming tool assembly I also includes a tool mounting plate II and a floating plate II, the edge trimming tool assembly II also includes a floating plate III, and telescopic springs and spring guide pins are provided between the tool mounting plate I and the floating plate I, between the tool mounting plate II and the floating plate II, and between the floating plate III and the tail mounting block II. Through holes are provided on the floating plate I and the floating plate II, and guide holes are provided on the tool mounting plate I, the tool mounting plate II, the lifting plate and the tail mounting block II.

[0010] In this solution, telescopic springs and spring guides are used to achieve vertical expansion and contraction of floating plates I, II, and III. This allows floating plates I and II to remain stationary relative to the workbench when encountering resistance, allowing the punching tool, end cutting tool, and corresponding trimming tool to extend. Simultaneously, the trimming tool on floating plate III descends to perform punching, grooving, cutting to length, and lip removal on the semi-finished rubber strip. Once the lifting plate ascends and returns to its original position, the tools are reset and no longer exposed, preventing workers from being injured by the tools.

[0011] Optionally, the bottom surface of the floating plate I is provided with a lip receiving groove for the lip of the semi-finished rubber strip to be placed.

[0012] In this solution, during the descent of the lifting plate, the bottom surface of the floating plate I contacts the semi-finished rubber strip placed on the mounting seat I and presses the semi-finished rubber strip tightly, thereby preventing the semi-finished rubber strip from moving on the mounting seat I, and there is no need to install a clamping part on the workbench to clamp the semi-finished rubber strip.

[0013] Optionally, both ends of the mounting base I are provided with a beam switch, and an indicator I is installed on the workbench. When the middle of the beam switch is blocked, the indicator I works.

[0014] In this solution, after the semi-finished rubber strip is placed on the mounting seat I, the transmitting switch is used to detect whether the end of the semi-finished rubber strip is in place, and the worker is prompted through the indicator I, thereby ensuring that the end cutting tool can cut off the end of the semi-finished rubber strip after cutting, and thus ensuring that the length of the semi-finished rubber strip after cutting meets the requirements.

[0015] Optionally, a proximity switch I is provided on the side of the first mounting block II away from the middle mounting block II, and an in-place detection component is provided between the proximity switch I and the first mounting block II. The in-place detection component includes a fixed block and a detection piece. The fixed block is provided with a detection hole for the end of the detection piece to pass through. A reset spring for resetting the detection piece is provided between the detection piece and the fixed block, and the end of the detection piece away from the fixed block extends into the placement groove II of the first mounting block II; an indicator II is installed on the workbench, and when the proximity switch I detects that the detection piece is pushed into place, the indicator II works.

[0016] In this solution, the semi-finished rubber strip, after being processed on mounting seat I, is removed and placed on mounting seat II. The in-place detection component detects whether the semi-finished rubber strip has moved into position, and an indicator II prompts the worker. The semi-finished rubber strip slides within the placement groove II of the first mounting seat II toward the detection member until it contacts the detection member. The detection member is then pushed toward the fixed block, and the end of the detection member moves toward the proximity switch I. After the detection member contacts the fixed block, the proximity switch I detects that the detection member has moved into position, and the indicator II activates, notifying the worker that the semi-finished rubber strip has moved into position, thereby ensuring the correct lip cut position.

[0017] Optionally, a driving member I for driving the longitudinal sliding plate to slide longitudinally is fixedly installed on the workbench, and a proximity switch II is also provided on the workbench. When the proximity switch II detects that the longitudinal sliding plate has moved into place, the driving member I stops moving.

[0018] In this solution, the longitudinal sliding plate is achieved by using the drive member I, eliminating the need for manual pushing and pulling of the longitudinal plate, thus reducing the workload of workers. Furthermore, the proximity switch II is used to detect whether the longitudinal plate has moved into position, thereby controlling the drive member I to achieve precise movement of the longitudinal plate.

[0019] Optionally, a driving member II for driving the tail mounting block II to slide laterally is fixedly mounted on the workbench, and a proximity switch III is also provided on the workbench. When the proximity switch III detects that the tail mounting block II has moved into place, the driving member II stops moving.

[0020] In this solution, driver II is used to achieve lateral sliding of tail mounting block II, eliminating the need for manual pushing and pulling of tail mounting block II, reducing worker workload. Furthermore, proximity switch III detects whether tail mounting block II is in place, thereby controlling driver II to achieve precise movement of tail mounting block II.

[0021] Optionally, the workbench is provided with a limiter I and a limiter II. When the longitudinal moving plate slides longitudinally into place, it abuts against the limiter I. When the tail mounting block II slides transversely into place, it abuts against the limiter II.

[0022] In this solution, the longitudinal plate slides into position when it abuts against limiter I after sliding longitudinally; and the tail mounting block II slides into position when it abuts against limiter II after sliding transversely. This ensures that if drive member I and / or drive member II malfunction, the longitudinal plate and / or tail mounting block II can be manually pushed and slid into position.

[0023] Optionally, a guide column and a spring support are provided between the lifting plate and the workbench.

[0024] In this solution, the guide column is used to limit the lifting plate to move only in the vertical direction, and the spring support is used to realize the reset of the lifting plate.

[0025] Optionally, the workbench is provided with a plurality of blanking openings II.

[0026] In this solution, the waste generated during the grooving, punching, cut-to-length and lip cutting processes falls through the blanking port II, preventing the waste from accumulating on the workbench. BRIEF DESCRIPTION OF THE DRAWINGS

A guide cylinder 5 is fixedly mounted on the bottom surface of the lifting plate 2. The lifting plate 2 is provided with a guide channel for the guide column 3 to pass through and a countersunk hole for the anti-slip plate 6 to be embedded. In this way, when the lifting plate 2 is subjected to downward pressure, it descends along the guide column 3. When the pressure disappears, it rises and resets under the action of the spring struts 4 and will not detach from the guide column 3. In addition, in this embodiment, the lifting plate 2 is lowered by a hydraulic cylinder, which is not shown.

[0042] The bottom surface of the lifting plate 2 is installed with a trimming tool assembly I7, an end tool assembly I8, a punching tool assembly 9 and an end tool assembly II10. A longitudinal sliding plate 11 is connected to the workbench 1 for longitudinal sliding. Specifically, four longitudinal guide rails 12 are fixedly installed on the workbench 1. A longitudinal slider 13 that slides with the longitudinal guide rails 12 is fixedly installed on the bottom surface of the longitudinal sliding plate 11, thereby realizing the longitudinal sliding of the longitudinal sliding plate 11 and preventing it from sliding horizontally. Figure 5 As shown, a proximity switch II 14 and a driving member I 15 for driving the longitudinal sliding plate 11 to slide longitudinally are fixedly installed on the workbench 1. There are two proximity switches II 14, and the proximity switches II 14 are arranged at the front and rear ends of the driving member I 15 to detect whether the longitudinal sliding plate 11 slides longitudinally into place. In this embodiment, the driving member I 15 is a magnetically coupled rodless cylinder.

[0043] The longitudinal plate 11 is provided with a mounting seat I 16 and a mounting seat II 17. The mounting seat I 16 includes a first mounting block I 1601, an intermediate mounting block I 1602, and a rear mounting block I 1603. The mounting seat II 17 includes a first mounting block II 1701, an intermediate mounting block II 1702, and a rear mounting block II 1703. The rear mounting block II 1703 is provided with a trimming tool assembly II 18. The end tool assembly I 8 and the end tool assembly II 10 both include an end cutting tool 19 and a punching tool 20. The end tool assembly I 8 also includes a grooving tool 21. The punching tool assembly 9 includes a punching tool 20.

The tool mounting plate I 23 and the tool mounting plate II 25 are both fixedly mounted on the bottom surface of the lifting plate 2, the end cutting tool 19, the groove cutting tool 21 and the punching tool 20 are fixedly mounted on the corresponding tool mounting plate I 23, and the trimming tool 22 is fixedly mounted on the tool mounting plate II 25 and the floating plate III 27; between the tool mounting plate I 23 and the floating plate I 24, between the tool mounting plate II 25 and the floating plate II 26, and between the floating plate III 27 and the tail mounting block II 1703, there are telescopic springs 28 and spring guide pins 29; the floating plate I 24 and the floating plate II 26 are both provided with through holes for the tool to pass through; the tool mounting plate I 23, the tool mounting plate II 25, the lifting plate 2 and the tail mounting block II 1703 are all provided with guide holes for the spring guide pins 29 to pass through; combined Figure 6 As shown, the bottom surface of the floating plate I 24 is provided with a lip receiving groove 2401 for the lip of the semi-finished rubber strip to be placed.

[0044] The first mounting block I 1601, the middle mounting block I 1602, and the tail mounting block I 1603 are all fixedly mounted on the longitudinally movable plate 11. In this embodiment, there are three middle mounting blocks I 1602. Each of the first mounting block I 1601, the middle mounting block I 1602, and the tail mounting block I 1603 is provided with a receiving groove I 30 for placing the semi-finished rubber strip and a channel 31 for the punching tool 20 to pass through. The first mounting block I 1601 is also provided with a cutting groove I 32 for the grooving tool 21 to pass through. In this embodiment, the first mounting block I 1601, the middle mounting block I 1602, and the tail mounting block I 1603 each have two receiving grooves I 30 to accommodate two semi-finished rubber strips for processing.

[0045] The first mounting block II 1701 and the middle mounting block II 1702 are provided with a receiving groove II 33 for placing the semi-finished rubber strip. The first mounting block II 1701 is also equipped with a pressure roller 34 for pressing the semi-finished rubber strip and a guide wheel 35 for guiding. The tail mounting block II 1703 is mounted on the workbench 1 for transverse sliding. Specifically, the workbench 1 is fixedly mounted with two transverse guide rails 36. The bottom surface of the tail mounting block II 1703 is fixedly mounted with a transverse slider 37 that slidably cooperates with the transverse guide rails 36, thereby enabling the tail mounting block II 1703 to slide laterally and preventing it from sliding longitudinally. The workbench 1 is fixedly mounted with a proximity switch III 38 and a driving member II 39 for driving the tail mounting block II 1703 to slide laterally. There are two proximity switches III 38, which are located at the left and right ends of the driving member II 39 to detect whether the tail mounting block II 1703 has slid into place laterally. In this embodiment, the driving member II 39 is a magnetically coupled rodless cylinder. The longitudinal plate 11 is provided with a notch for the tail mounting block II 1703 to slide into. Figure 4 As shown, the tail mounting block II 1703 is provided with a channel 40 for the semi-finished rubber strip to pass through. The tail mounting block II 1703 and the first mounting block II 1701 are both provided with a cutting groove II 41 for the edge trimming tool 22 to pass through. The cutting groove II 41 on the first mounting block II 1701 is connected to the receiving groove II 33 on the first mounting block II 1701 and passes through the first mounting block II 1701. The cutting groove II 41 on the tail mounting block II 1703 is connected to the channel 40 on the tail mounting block II 1703 and passes through the tail mounting block II 1703. In this embodiment, the number of receiving grooves II 33 on both the first mounting block II 1701 and the middle mounting block II 1702 is two, and the number of channels 40 on the tail mounting block II 1703 is two, so as to accommodate two semi-finished rubber strips for processing.

[0046] The longitudinal moving plate 11 is provided with a plurality of blanking openings I 42 , and the workbench 1 is provided with a plurality of blanking openings II 43 . The blanking openings I 42 and II 43 are used for dropping waste generated during the grooving, punching, fixed-length cutting and lip edge cutting processes to avoid waste accumulation on the longitudinal moving plate 11 and the workbench 1 .

[0047] Combine Figure 3 As shown, both ends of the mounting base Ⅰ16 are provided with a beam switch 44, which is fixedly mounted on the longitudinal plate 11. An indicator Ⅰ45 is fixedly mounted on the workbench 1. When the middle of the beam switch 44 is blocked, the indicator Ⅰ45 works. A proximity switch Ⅰ46 is fixedly mounted on the longitudinal plate 11. A position detection component 47 is provided between the proximity switch Ⅰ46 and the first mounting block Ⅱ1701. Figure 7 and Figure 8 As shown, the in-place detection component 47 includes a fixed block 4701 and a detection member 4702, the detection member 4702 includes a cross-shaped detection body 47021 and a guide rod 47022, the right end of the cross-shaped detection body 47021 extends into the mounting groove Ⅱ33 of the first mounting block Ⅱ1701, and the guide rod 47022 is integrally formed on the left side wall of the cross-shaped detection body 47021, and a reset spring 4703 is wound around the guide rod 47022; the fixed block 4701 is provided with a detection hole 47011 for the left end of the cross-shaped detection body 47021 to pass through and a guide hole 47012 for the guide rod 47022 to pass through, the guide hole 47012 includes a guide section and an expansion section for accommodating the reset spring 4703, one end of the reset spring 4703 is abutted against the left side wall of the cross-shaped detection body 47021, and the other end of the reset spring 4703 is abutted against the radial hole wall of the expansion section. An indicator II 48 is fixedly mounted on the workbench 1. When the proximity switch I 46 detects that the detection member 4702 is pushed into place, the indicator II 48 starts to work. In this embodiment, both the indicator I 45 and the indicator II 48 are indicator lights.

[0048] When in use, the semi-finished rubber strip is placed in the placement groove I30 on the mounting seat I16. The two ends of the semi-finished rubber strip respectively block the middle of the corresponding shooting switch 44, and the corresponding indicator I45 lights up (the corresponding indicator I45 will light up only after the shooting switches 44 at both ends of the mounting seat I16 are blocked), indicating that the semi-finished rubber strip is in place. Subsequently, the driving member I15 drives the longitudinal plate 11 to slide backward, so that the semi-finished rubber strip moves to the bottom of the end tool assembly I8, the punching tool assembly 9 and the end tool assembly II10, as shown in FIG. Figure 5As shown. During this process, after the proximity switch Ⅱ14 detects that the longitudinal plate 11 has slid backward into position, the driving member Ⅰ15 no longer drives the longitudinal plate 11 to slide longitudinally. At this time, the knife groove Ⅰ32 corresponds to the grooving tool 21, the channel 31 corresponds to the punching tool 20, the two ends of the mounting seat Ⅰ16 correspond to the cutting end tool 19, and the knife groove Ⅱ41 on the first mounting block Ⅱ1701 corresponds to the trimming tool 22 of the trimming tool assembly Ⅰ7. Then, driven by the driving member Ⅱ39, the tail mounting block Ⅱ1703 slides to the left and enters the gap of the longitudinal plate 11. During this process, after the proximity switch Ⅲ38 detects that the tail mounting block Ⅱ1703 has slid to the left into position, the driving member Ⅱ39 no longer drives the tail mounting block Ⅱ1703 to slide horizontally. At this time, the knife groove Ⅱ41 on the tail mounting block Ⅱ1703 corresponds to the trimming tool 22 of the trimming tool assembly Ⅱ18.

[0049] Next, the hydraulic cylinder drives the lifting plate 2 downward, and the trimming tool assembly I7, end tool assembly I8, punching tool assembly 9, and end tool assembly II10 also move downward. As the lifting plate 2 moves downward, the bottom surface of the floating plate I24 contacts the semi-finished rubber strip placed on the mounting seat I16, pressing and securing the semi-finished rubber strip. After the floating plate I24 comes to rest relative to the longitudinal plate 11, the trimming tool 19, punching tool 20, and grooving tool 21 emerge from the bottom surface of the floating plate I24. The trimming tool 19 cuts the end of the semi-finished rubber strip (completing the fixed-length cut), the punching tool 20 punches the semi-finished rubber strip, and the grooving tool 21 grooves the semi-finished rubber strip. After the floating plate II26 contacts the first mounting block II1701 and remains stationary relative to the first mounting block II1701, the trimming tool 22 of the trimming tool assembly I7 emerges from the bottom surface of the floating plate II26 and enters the corresponding tool groove II41. The floating plate III 27 moves downward under the push of the lifting plate 2 , and the trimming tool 22 of the trimming tool assembly II 18 moves downward and enters the corresponding tool groove II 41 .

[0050] After punching, grooving, and cutting the semi-finished rubber strip to length, the hydraulic cylinder's output end moves upward, no longer exerting downward pressure on the lifting plate 2. Driven by the spring struts 4, the lifting plate 2 moves upward and resets, thereby driving the trimming tool assembly I7, the end tool assembly I8, the punching tool assembly 9, and the end tool assembly II10 upward and reset. During this process, the end cutting tool 19, the punching tool 20, and the grooving tool 21 return to the floating plate I24, and the trimming tool 22 of the trimming tool assembly I7 returns to the floating plate II26. Simultaneously, the trimming tool assembly II18 resets. Specifically, as the lifting plate 2 moves upward, the floating plate III27 moves upward under the action of the telescopic spring 28 in the trimming tool assembly II18, and the trimming tool 22 on the bottom surface of the floating plate III27 moves upward and resets accordingly.

[0051] After the lifting plate 2 moves upward and resets, the driver II 39 drives the tail mounting block II 1703 to slide rightward. When the proximity switch III 38 detects that the tail mounting block II 1703 has slid rightward and reset, the driver II 39 no longer drives the tail mounting block II 1703 to slide horizontally. Next, the driver I 15 drives the longitudinal plate 11 to slide forward. When the proximity switch II 14 detects that the longitudinal plate 11 has slid forward and reset, the driver I 15 no longer drives the longitudinal plate 11 to slide longitudinally.

[0052] The worker then removes the semi-finished rubber strip from mounting seat I16, after punching, grooving, and cutting to length. The strip is then placed in slot II33 of intermediate mounting block II1702 and its left end is pushed into slot II33 of primary mounting block II1701. With the cooperation of pressure roller 34 and guide wheel 35, the left end of the strip slides to the left side of primary mounting block II1701, where it abuts against the right end of cross-shaped detection body 47021, pushing cross-shaped detection body 47021 to the left, overcoming the force of return spring 4703. Once proximity switch I46 detects that the left end of cross-shaped detection body 47021 has moved into position, indicator II48 illuminates, indicating that the strip is now in position within slot II33. Once in position, the pressure of pressure roller 34 prevents the strip from moving back to the right.

[0053] After the two semi-finished rubber strips that have been grooved, punched, and cut to length are placed in place, the worker takes two new semi-finished rubber strips to be processed and places them on the mounting seat Ⅰ16, and determines whether they are in place by whether the indicator Ⅰ45 lights up. After the semi-finished rubber strips on the mounting seat Ⅰ16 are placed in place, the driving member Ⅰ15 drives the longitudinal plate 11 to slide backward, so that the semi-finished rubber strips move to the bottom of the end tool assembly Ⅰ8, ​​the punching tool assembly 9 and the end tool assembly Ⅱ10. Then, the driving member Ⅱ39 drives the tail mounting block Ⅱ1703 to slide to the left, so that the right end of the semi-finished rubber strip placed on the mounting groove Ⅱ33 passes through the channel 40 on the tail mounting block Ⅱ1703, and makes the knife groove Ⅱ41 of the tail mounting block Ⅱ1703 and the first mounting block Ⅱ1701 correspond to the trimming tool 22, as shown in FIG. Figure 9As shown. Next, the hydraulic cylinder drives the lifting plate 2 downward, and the cutting tool 19, punching tool 20, and cutting tool 19 all emerge from the bottom surface of the floating plate I 24 to cut, punch, and groove the semi-finished rubber strip on the mounting seat I 16. Simultaneously, the trimming tool 22 enters the slit II 41 and trims the lip edge of the semi-finished rubber strip on the mounting seat II 17. In this way, the semi-finished rubber strip on the mounting seat I 16 is grooved, punched, and cut to length, while the semi-finished rubber strip on the mounting seat II 17 is trimmed. Furthermore, the waste generated during the above process falls through the dropout openings I 42 and II 43 into a waste collection drum (not shown) below the workbench 1.

[0054] After the grooving, punching, cutting to length, and lip trimming processes are completed, the lifting plate 2 moves upward and resets, the tail mounting block II 1703 slides rightward and resets, and the longitudinal plate 11 slides forward and resets. The worker first removes the semi-finished rubber strip from mounting seat II 17 after the lip trimming and places it in the finished product frame. At this time, indicator II 48 goes out. Then, the semi-finished rubber strip from mounting seat I 16 after grooving, punching, and cutting to length is removed (at this time, indicator I 45 goes out) and placed on mounting seat II 17. Two new semi-finished rubber strips to be processed are placed on mounting seat I 16. The post-processing of the semi-finished rubber strips is repeated.

[0055] In this way, in this embodiment, the grooving, punching, cutting to length and lip cutting processes of the semi-finished rubber strip are integrated on the same equipment, which effectively reduces the number of equipment and the equipment footprint, reduces the workload of workers, and greatly improves production efficiency.

[0056] Example 2

[0057] The difference between this embodiment and the first embodiment is that: Figure 10 and Figure 11 As shown, in this embodiment, a limiter I 49 and a limiter II 50 are fixedly installed on the workbench 1. When the longitudinal plate 11 slides backward into position, it abuts against the limiter I 49. When the tail mounting block II 1703 slides leftward into position, it abuts against the limiter II 50. A sensor 51 is also provided on the limiter I 49 and the limiter II 50. Specifically, the sensor 51 can be a pressure sensor or a distance sensor. When the sensor 51 on the limiter I 49 detects that the longitudinal plate 11 abuts against the limiter I 49, the drive member II 39 is activated (the drive member II 39 is controlled to operate by the controller), driving the tail mounting block II 1703 to slide leftward. When the sensor 51 on the limiter II 50 detects that the tail mounting block II 1703 abuts against the limiter II 50, the hydraulic cylinder is activated (the hydraulic cylinder is controlled to operate by the controller), driving the lifting plate 2 to move downward.

[0058] Thus, in this embodiment, after the longitudinal moving plate 11 slides backward into position, the driving member II 39 starts automatically, thereby driving the tail mounting block II 1703 to slide to the left, and when the tail mounting block II 1703 slides to the left into position, the hydraulic cylinder starts automatically, without the need for manual control by the worker, thereby reducing the worker's operation workload and improving the continuity of the processing of the semi-finished rubber strips.
