Description

Technical Field

[0001] This utility model belongs to the field of rubber punching technology, specifically relating to a semi-automatic rubber punching device. Background Technology

[0002] Punching is a common process in the manufacturing of rubber products. Whether it's rubber gaskets for sealing, rubber sheets with specific ventilation requirements, or other rubber parts that need pre-drilled mounting holes or functional holes, punching equipment is often used to process the corresponding holes. Currently, the semi-automatic rubber punching equipment used in the industry has a relatively fixed structure and operating mode to meet basic punching operation needs. Existing rubber punching machines typically consist of a mold plate as their core operating structure. This mold plate has several pre-drilled holes matching the required hole shape and diameter, based on the hole design requirements of the rubber part to be processed. These holes serve as positioning references for punching the rubber material and as channels for waste material discharge or finished hole formation after punching. In actual operation, the operator manually places the rubber material to be punched flat on the mold plate, ensuring accurate alignment between the punching position and the corresponding mold hole. The punching machine is then started, and the punch head moves downwards under the drive mechanism, passing through the rubber material and entering the mold hole to complete one punching operation. After punching in that area is complete, the operator manually removes the punched rubber part from the mold plate. To punch the next piece of rubber material, the "place-punch-remove" process is repeated. However, existing semi-automatic rubber punching devices have significant limitations in practical applications. First, the single mold plate results in large operational gaps. Since operations can only be performed on a single mold plate at a time, after punching a batch of rubber, the operator must manually remove the finished product, place the new rubber material to be processed on the mold plate, and adjust its position before starting the machine for the next batch of punching. During this "removal-feeding-adjustment" process, the punching machine is completely idle, resulting in a low percentage of effective operating time and hindering overall production efficiency. Second, parallel processing and auxiliary operations are impossible. Because there is only one mold plate, which must be fixed below the punching machine, operators cannot perform auxiliary operations such as placing rubber to be processed or removing processed rubber while the machine is punching. They can only perform subsequent auxiliary preparations after the punching machine completes the current batch and stops, further exacerbating the intermittent nature of operations and failing to meet the demands of large-scale, high-efficiency rubber processing. Utility Model Content

[0003] In view of this, the present invention provides a semi-automatic rubber punching device to solve the problems of poor processing continuity and large working gaps resulting in low effective working time of the equipment in the prior art due to the single configuration of the mold plate.

[0004] The technical solution adopted in this utility model is as follows: A semi-automatic rubber punching device includes a worktable with a rotating shaft rotatably connected to it. The rotating shaft is driven by a motor located below the worktable. A circular plate is fixedly connected to the top of the rotating shaft. A plurality of chip outlets are provided through the top of the circular plate, and the chip outlets are equidistantly spaced along the circumference of the circular plate. A mold plate is provided above each chip outlet, and a plurality of mold holes communicating with the chip outlets are provided through the mold plate. A support is provided on one side of the worktable, and a punching machine is provided on the support, located above one of the mold plates.

[0005] In this technical solution, it should be noted that the workbench, as the basic load-bearing component, is used to install various components such as the rotating shaft and the support, providing a stable operating platform for the overall operation; the rotating shaft transmits the motor power to drive the circular plate to rotate; the motor provides the driving force for the rotation of the circular plate; the circular plate is made of stainless steel, with a diameter of 90cm-150cm, and serves as the mounting carrier for the mold plate. The rotation allows for switching between different mold plate positions, and the chip outlet at the top is used to discharge rubber waste generated during punching; the mold plate is set correspondingly to the chip outlet, and the mold holes on it guide the punching machine to punch and discharge the waste through the chip outlet; the support is used to fix the punching machine, ensuring that the punching machine is in a stable operating position. Its working principle is as follows: After the motor starts, it drives the rotating shaft to rotate, which in turn drives the circular plate and several mold plates on the circular plate to rotate synchronously. When one of the mold plates rotates to be directly under the punching machine, the circular plate stops rotating, and the punching machine punches the rubber parts to be punched on the mold plate. Waste material falls through the mold holes into the chip outlet and is discharged. At the same time, the operator can place rubber parts to be processed or remove processed rubber parts on other mold plates not under the punching machine. After the rubber on the current mold plate is punched, the motor drives the circular plate to rotate again, rotating the next mold plate containing the rubber parts to be punched to be under the punching machine, and repeating the above operation process. By setting up a rotatable circular plate and several mold plates on the circular plate, combined with a fixed-position punching machine, the punching operation and auxiliary operations such as rubber part placement and removal can be carried out in parallel, effectively shortening the operation interval, increasing the effective working time ratio of the equipment, and thus improving the overall production efficiency.

[0006] Preferably, the punching machine includes a cylinder, which is vertically mounted on a support. A mounting plate is connected to the piston rod of the cylinder. The mounting plate is provided with a plurality of punching posts corresponding to the die holes. A pressure plate is connected to the bottom of the mounting plate by a first spring. A plurality of through holes corresponding to the punching posts are provided through the pressure plate.

[0007] In this technical solution, it should be noted that the cylinder is a common pneumatic actuator in existing technology. It uses the pressure of compressed air to drive the internal piston to move, which in turn drives the piston rod to extend and retract vertically, thus providing a stable driving force for the punching operation. After being fixed on the bracket, the cylinder drives the subsequent components to complete the punching action through the movement of the piston rod. The mounting plate serves as a load-bearing and connecting element. On one hand, it is connected to the cylinder piston rod to receive power, and on the other hand, it is used to install the punching post to ensure the stability of the punching post's position. The punching post moves downward under the drive of the cylinder and can pass through the rubber part to be punched to achieve punching. The first spring has an elastic buffering and restoring function, which can provide a downward preload to the pressure plate and assist the pressure plate in restoring after punching. The pressure plate is used to press the rubber part to be processed before punching to prevent the rubber part from shifting during punching. The perforation on the pressure plate corresponds to the punching post, which can ensure that the punching post passes through smoothly for punching. When the punching machine is operating, compressed air is introduced into the cylinder, and the piston rod extends downward, causing the mounting plate, punching pin, and pressure plate to move downward synchronously. The pressure plate first contacts the rubber part on the mold plate. As the mounting plate continues to move downward, the first spring is compressed, and the pressure plate tightly presses the rubber part under the action of the spring force. Then, the punching pin passes through the perforation on the pressure plate to punch the rubber part. After punching is completed, the cylinder exhausts air, and the piston rod retracts upward under the action of internal air pressure. The mounting plate moves the punching pin upward, and the first spring rebounds to push the pressure plate to reset, releasing the pressure on the rubber part.

[0008] Preferably, the mold plate is fixed to the circular plate by a fixing device, the fixing device including a screw rod, the screw rod being vertically mounted on the circular plate, a fixing plate being slidably sleeved on the screw rod, and a nut being threadedly connected to the screw rod, the nut being located above the mold plate.

[0009] In this technical solution, it should be noted that the fixing device is used to fix the mold plate onto the circular plate, while facilitating the disassembly and replacement of the mold plate; the screw is vertically fixed on the circular plate, serving as the mounting carrier for the fixing plate and nut, providing support for the fixing of the mold plate; the fixing plate is slidably sleeved on the screw, allowing it to move along the screw and press against the top of the mold plate; the nut is threadedly connected to the screw, and tightening the nut pushes the fixing plate downward to press the mold plate, while loosening it releases the fixing of the mold plate. The fixing and disassembly process is as follows: When installing the mold plate, first place the mold plate corresponding to the chip outlet on the circular plate, aligning the mold hole with the chip outlet. Then, place the fixing plate on the screw and position it on top of the mold plate. Tighten the nut, which moves downward on the screw and pushes the fixing plate, pressing it tightly against the mold plate and firmly fixing it in place; when replacing the mold plate, loosen the nut in the opposite direction and move the fixing plate upward to detach it from the mold plate, allowing the mold plate to be removed from the circular plate. By setting up a fixing device, it is possible to ensure that the mold plate does not shift during the punching operation, thus guaranteeing the punching accuracy. At the same time, the mold plate can be quickly disassembled and assembled by simply turning the nut, which improves the flexibility of the equipment in processing rubber parts of different specifications.

[0010] Preferably, a washer is also fitted onto the screw, and the washer is located between the nut and the fixing plate.

[0011] In this technical solution, it should be noted that the washer, typically made of metal, is fitted onto the screw and located between the nut and the fixing plate. It serves to distribute pressure and protect the components. When the nut is tightened, the pressure of the nut is transmitted to the fixing plate through the washer. The washer increases the contact area, preventing excessive local pressure caused by direct contact between the nut and the fixing plate, thus preventing damage to the surface of the fixing plate from the nut. Simultaneously, the washer reduces friction between the nut and the fixing plate, making tightening the nut more stable and indirectly improving the stability of the mold plate.

[0012] Preferably, a guide rail is provided below the worktable, and a base plate is slidably connected to the guide rail. A chip collection box is provided on the top of the base plate and is located below the punching machine. The system also includes a linkage component that drives the rotating shaft and the chip collection box. When the rotating shaft rotates, the chip collection box can be driven to move back and forth through the linkage component.

[0013] In this technical solution, it should be noted that the guide rail is fixed below the worktable, providing stable guidance for the sliding of the base plate and ensuring that the base plate drives the chip collection box to move smoothly along the preset trajectory, avoiding deviation. The chip collection box is located on top of the base plate, directly below the punching machine during punching operations to accurately collect waste material. Its distribution of debris within the box can be adjusted as the base plate moves. The linkage component transmits power to the rotating shaft, converting the shaft's rotation into the reciprocating motion of the base plate only at specific stages. Its working principle is as follows: When the device is in punching operation, the chip collection box remains stationary below the current punching die plate, stably collecting rubber debris falling from the chip outlet. When punching is complete and it is necessary to switch to the next die plate, the motor drives the rotating shaft to rotate. The rotation of the shaft, through the linkage component, causes the base plate to slide back and forth along the guide rail a short distance, i.e., the chip collection box moves back and forth on the guide rail with the base plate, and then stops. During this process, the chip collection box utilizes the inertia and shaking of the debris within the box to disperse debris that might have accumulated locally. By using the linkage components and the chip collection box, and with the power of the rotating shaft, the collected chips are evenly spread out in the chip collection box, preventing them from piling up in local areas, increasing the effective capacity of the chip collection box, and adapting to the needs of large chip volume in rubber batch processing.

[0014] Preferably, the base plate is provided with a second spring connected to the end of the guide rail, and a plate is provided on one side of the guide rail, the plate being located between the rotating shaft and the guide rail; the linkage assembly includes a linkage shaft and an incomplete gear, the linkage shaft is rotatably connected to the plate, the linkage shaft is arranged parallel to the rotating shaft, the incomplete gear is fixedly sleeved on the linkage shaft, and the linkage shaft and the rotating shaft are connected by a conveyor belt; a rack is provided on the side wall of the base plate, the rack is arranged along the length direction of the base plate, and the rack meshes with the incomplete gear.

[0015] In this technical solution, it should be noted that the second spring is connected between the base plate and the end of the guide rail, and has an elastic reset function. It can provide a reverse force after the base plate moves under force, driving the base plate back to its initial position. The plate is located between the rotating shaft and the guide rail, serving as the mounting carrier for the linkage shaft and providing stable support for the rotation of the linkage shaft. The incomplete gear only has teeth on some parts, and can achieve discontinuous movement of the base plate through intermittent meshing with the rack. The conveyor belt connects the rotating shaft and the linkage shaft, and can synchronously transmit the rotational power of the rotating shaft to the linkage shaft, so that the two maintain linkage rotation. Its working principle is as follows: When the device is in the punching state, the rotating shaft is stationary, the linkage shaft stops rotating with the rotating shaft, the base plate remains stationary under the natural tension of the second spring, and the chip collection box is stably located below the chip outlet of the current punching die plate to receive waste material; when punching is completed and the next die plate needs to be switched, the motor drives the rotating shaft to rotate, and the rotating shaft drives the linkage shaft to rotate synchronously through the conveyor belt. The incomplete gear on the linkage shaft rotates accordingly. When the toothed part of the incomplete gear rotates to mesh with the rack, it will push the rack to drive the base plate to move away from the second spring along the guide rail, while stretching or compressing the second spring; when the toothless part of the incomplete gear rotates to the rack position, the gear disengages from the rack, the second spring releases its elastic force to drive the base plate to move in the opposite direction and reset; thus driving the base plate and the chip collection box to reciprocate during the non-punching stage of die switching. In this solution, the intermittent meshing of the incomplete gear and rack, combined with the reset action of the second spring, precisely enables the chip collection box to reciprocate only during the non-punching phase of mold switching. This avoids the chip collection box movement during punching from affecting the accuracy of waste material collection, and the reciprocating motion ensures that the chips inside the box are evenly distributed, preventing local accumulation. At the same time, with the help of the conveyor belt and the rotating shaft linkage, synchronous control can be achieved without an additional power source. The structure is compact and suitable for batch processing needs.

[0016] Preferably, the base plate is provided with a T-shaped groove, the top of the chip collection box is provided with a T-shaped block, the T-shaped block is slidably embedded in the T-shaped groove, one end of the T-shaped groove penetrates the base plate and forms an entrance for the T-shaped block to be inserted.

[0017] In this technical solution, it should be noted that the quick assembly and disassembly of the chip collection box is achieved through the sliding fit structure of the T-slot and the T-block.

[0018] Preferably, the T-slot has a groove, the groove has a third spring, the top of the third spring has a stop block connected to it, the stop block extends outside the groove, and the stop block is located at the entrance.

[0019] In this technical solution, it should be noted that during installation of the dust collection box, the stop block is pressed into the groove, then the T-block is aligned with the entrance of the T-slot and pushed in. After the T-block is fully inserted into the T-slot, the third spring rebounds, pushing the stop block out of the groove. The stop block then locks behind the T-block, preventing the dust collection box from accidentally sliding out. For disassembly, manually press the stop block to retract it into the groove, releasing the obstruction to the T-block, and then pull the dust collection box out along the entrance direction. By adding the groove, the third spring, and the stop block in a coordinated structure, without affecting the normal loading and unloading of the dust collection box, it effectively prevents the dust collection box from slipping out of the T-slot due to vibration or other factors when it moves back and forth with the base plate, further improving the stability of the dust collection box installation and ensuring its reliable collection of waste materials.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, by setting a rotatable circular plate and several mold plates on the circular plate, and cooperating with a punching machine in a fixed position, the punching operation and auxiliary operations such as picking up and placing rubber parts can be carried out in parallel, which effectively shortens the operation interval, increases the effective operation time ratio of the equipment, and thus improves the overall production efficiency. 2. In this utility model, the intermittent meshing of the incomplete gear and rack, combined with the reset action of the second spring, precisely realizes that the chip collection box only moves back and forth during the non-punching stage of mold switching. This not only avoids the chip collection box moving during punching from affecting the accuracy of waste material collection, but also makes the chips in the box evenly distributed through the reciprocating motion, preventing local accumulation. At the same time, with the help of the conveyor belt and the rotating shaft linkage, synchronous control can be achieved without an additional power source. The structure is compact and suitable for batch processing needs. Attached Figure Description

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0028] Example 1: like Figures 1-9As shown in the figure, a semi-automatic rubber punching device is disclosed in this embodiment of the utility model, including a workbench 800, on which a rotating shaft 300 is rotatably connected. The rotating shaft 300 is driven by a motor 700 located below the workbench 800. A circular plate 100 is fixedly connected to the top of the rotating shaft 300. A plurality of chip outlets 101 are provided through the top of the circular plate 100. The plurality of chip outlets 101 are equidistantly arranged along the circumference of the circular plate 100. A mold plate 200 is provided above each chip outlet 101. A plurality of mold holes 201 communicating with the chip outlets 101 are provided through the mold plate 200. A support 400 is provided on one side of the workbench 800. A punching machine is provided on the support 400. The punching machine is located above one of the mold plates 200. It should be noted that the workbench 800, as the basic load-bearing component, is used to install various components of the device such as the rotating shaft 300 and the bracket 400, providing a stable operating platform for the overall operation; the rotating shaft 300 transmits power from the motor 700 to drive the circular plate 100 to rotate; the motor 700 provides driving force for the rotation of the circular plate 100; the circular plate 100 is made of stainless steel and has a diameter of 90cm-150cm. It serves as the mounting carrier for the mold plate 200, and the rotation allows for switching between different positions of the mold plate 200. The chip outlet 101 at the top is used to discharge rubber waste generated during punching; the mold plate 200 is set corresponding to the chip outlet 101, and the mold hole 201 on it guides the punching machine to punch and discharges the waste through the chip outlet 101; the bracket 400 is used to fix the punching machine and ensure that the punching machine is in a stable operating position. Its working principle is as follows: After the motor 700 starts, it drives the rotating shaft 300 to rotate, which in turn drives the circular plate 100 and several mold plates 200 on the circular plate 100 to rotate synchronously. When one of the mold plates 200 rotates to the point directly below the punching machine, the circular plate 100 stops rotating. The punching machine punches the rubber parts to be punched on the mold plate 200. The waste material falls into the chip outlet 101 through the mold hole 201 and is discharged. At the same time, the operator can place the rubber parts to be processed or take out the processed rubber parts on other mold plates 200 that are not below the punching machine. After the rubber punching on the current mold plate 200 is completed, the motor 700 drives the circular plate 100 to rotate again, and rotates the next mold plate 200 containing the rubber parts to be punched to the point below the punching machine, and repeats the above operation process. By setting a rotatable circular plate 100 and several mold plates 200 on the circular plate 100, and cooperating with a punching machine in a fixed position, the punching operation and auxiliary operations such as picking up and placing rubber parts can be carried out in parallel, which effectively shortens the operation interval, increases the proportion of effective operation time of the equipment, and thus improves the overall production efficiency.

[0029] Example 2: like Figure 5As shown, this embodiment is largely the same as the above embodiment, except that the punching machine includes a cylinder 500, which is vertically mounted on the bracket 400. A mounting plate 501 is connected to the piston rod of the cylinder 500. The mounting plate 501 is provided with a plurality of punching posts 502 corresponding to the mold holes 201. A pressure plate 504 is connected to the lower part of the mounting plate 501 through a first spring 503. A plurality of through holes 505 corresponding to the punching posts 502 are provided through the pressure plate 504. It should be noted that the cylinder 500 is a common pneumatic actuator in existing technology. It uses the pressure of compressed air to drive the internal piston to move, which in turn drives the piston rod to extend and retract in the vertical direction, thus providing a stable driving force for the punching operation. After being fixed on the bracket 400, the piston rod drives the subsequent components to complete the punching action. The mounting plate 501 serves as a load-bearing and connecting element. On the one hand, it is connected to the piston rod of the cylinder 500 to receive power, and on the other hand, it is used to install the punching post 502 to ensure the stability of the punching post 502. The punching post 502 moves downward under the drive of the cylinder 500 and can pass through the rubber part to be punched to achieve punching. The first spring 503 has an elastic buffering and reset function, which can provide a downward preload to the pressure plate 504, and at the same time assist the pressure plate 504 to reset after punching. The pressure plate 504 is used to press the rubber part to be processed before punching to prevent the rubber part from shifting during punching. The through hole 505 on it corresponds to the punching post 502, which can ensure that the punching post 502 passes through smoothly for punching. When the punching machine is operating, compressed air is introduced into the cylinder 500, and the piston rod extends downward, causing the mounting plate 501, punching column 502, and pressure plate 504 to move downward synchronously. The pressure plate 504 first contacts the rubber part on the mold plate 200. As the mounting plate 501 continues to move downward, the first spring 503 is compressed, and the pressure plate 504 tightly presses the rubber part under the action of the spring force. Then, the punching column 502 passes through the perforation 505 on the pressure plate 504 to punch the rubber part. After punching is completed, the cylinder 500 exhausts air, and the piston rod retracts upward under the action of internal air pressure. The mounting plate 501 drives the punching column 502 to move upward, and the first spring 503 rebounds to push the pressure plate 504 to reset, releasing the pressure on the rubber part.

[0030] Example 3: like Figure 4As shown, this embodiment is largely the same as the above embodiment, except that the mold plate 200 is fixed on the circular plate 100 by a fixing device. The fixing device includes a screw 900, which is vertically mounted on the circular plate 100. A fixing plate 901 is slidably sleeved on the screw 900, and a nut 902 is threadedly connected to the screw 900. The nut 902 is located above the mold plate 200. It should be noted that the fixing device is used to fix the mold plate 200 onto the circular plate 100, and at the same time facilitates the disassembly and replacement of the mold plate 200; the screw 900 is vertically fixed on the circular plate 100, serving as the mounting carrier for the fixing plate 901 and the nut 902, providing support for the fixing of the mold plate 200; the fixing plate 901 is slidably sleeved on the screw 900, and can move on the screw 900, and can press against the top of the mold plate 200; the nut 902 is threadedly connected to the screw 900, and by tightening the nut 902, the fixing plate 901 can be pushed downward to press the mold plate 200, and by loosening it, the fixing of the mold plate 200 can be released. The fixing and disassembly process is as follows: When installing the mold plate 200, first place the mold plate 200 corresponding to the chip outlet 101 on the circular plate 100, aligning the mold hole 201 with the chip outlet 101. Then, put the fixing plate 901 on the screw 900 and place it on top of the mold plate 200. Subsequently, tighten the nut 902. The nut 902 moves downward on the screw 900 and pushes the fixing plate 901, which then presses tightly onto the mold plate 200, firmly fixing the mold plate 200. When it is necessary to replace the mold plate 200, loosen the nut 902 in the opposite direction and move the fixing plate 901 upward to detach it from the mold plate 200, thus removing the mold plate 200 from the circular plate 100. The fixing device ensures that the mold plate 200 does not shift during punching operations, guaranteeing punching accuracy, and allows for quick assembly and disassembly of the mold plate 200 through simple tightening and loosening of the nut 902, improving the equipment's flexibility in processing rubber parts of different specifications.

[0031] like Figure 4 As shown, in this embodiment, a washer 903 is also fitted onto the screw 900, and the washer 903 is located between the nut 902 and the fixing plate 901. It should be noted that the washer 903, fitted onto the screw 900 and located between the nut 902 and the fixing plate 901, is typically made of metal and serves to distribute pressure and protect components. When the nut 902 is tightened, the pressure of the nut 902 is transmitted to the fixing plate 901 through the washer 903. The washer 903 increases the force-bearing area, preventing excessive local pressure caused by direct contact between the nut 902 and the fixing plate 901, thereby preventing damage to the surface of the fixing plate 901 from the nut 902. Simultaneously, the washer 903 also reduces friction between the nut 902 and the fixing plate 901, making the tightening of the nut 902 more stable and indirectly improving the stability of the mold plate 200.

[0032] Example 4: like Figures 6-9 As shown, this embodiment is largely the same as the above embodiment, except that a guide rail 602 is provided below the worktable 800, and a base plate 601 is slidably connected to the guide rail 602. A chip collection box 600 is provided on the top of the base plate 601, and the chip collection box 600 is located below the punching machine. It also includes a linkage component, which drives the rotating shaft 300 and the chip collection box 600 to move back and forth through the linkage component when the rotating shaft 300 rotates. It should be noted that the guide rail 602 is fixed below the worktable 800, providing stable guidance for the sliding of the base plate 601, ensuring that the base plate 601 drives the chip collection box 600 to move smoothly along the preset trajectory and avoid deviation; the chip collection box 600 is located on the top of the base plate 601, and is directly below the punching machine during punching operations to accurately receive waste materials. Its distribution of debris inside the box can be adjusted as the base plate 601 moves; the linkage component is used to transmit the power of the rotating shaft 300, converting the rotation of the rotating shaft 300 into the reciprocating motion of the base plate 601 only at specific stages. Its working principle is as follows: When the device is in the punching operation state, the chip collection box 600 is stationary below the current punching die plate 200, stably receiving the rubber chips falling from the chip outlet 101. When punching is completed and it is necessary to switch to the next die plate 200, the motor 700 drives the rotating shaft 300 to rotate. The rotation of the rotating shaft 300 drives the base plate 601 to slide back and forth along the guide rail 602 a short distance through the linkage component. That is, the chip collection box 600 moves back and forth on the guide rail 602 with the base plate 601, and then stops. During this process, the chip collection box 600 uses the inertia and shaking of the chips inside the box to disperse the chips that might have accumulated in a local area. Through the setting of the linkage component and the chip collection box 600, with the power of the rotating shaft 300, the chips collected in the chip collection box 600 are evenly spread out, avoiding them from accumulating in a local pile, increasing the effective holding space of the chip collection box 600, and adapting to the needs of large chip volume in rubber batch processing.

[0033] like Figure 6As shown, in this embodiment, the base plate 601 is provided with a second spring 603 connected to the end of the guide rail 602. A plate 302 is provided on one side of the guide rail 602, and the plate 302 is located between the rotating shaft 300 and the guide rail 602. The linkage assembly includes a linkage shaft 303 and an incomplete gear 304. The linkage shaft 303 is rotatably connected to the plate 302 and is arranged parallel to the rotating shaft 300. The incomplete gear 304 is fixedly sleeved on the linkage shaft 303. The linkage shaft 303 and the rotating shaft 300 are connected by a conveyor belt 301. A rack 604 is provided on the side wall of the base plate 601. The rack 604 is arranged along the length direction of the base plate 601, and the rack 604 meshes with the incomplete gear 304. It should be noted that the second spring 603 is connected between the base plate 601 and the end of the guide rail 602, and has an elastic reset function. It can provide a reverse force after the base plate 601 is moved under force, driving the base plate 601 back to the initial position. The plate 302 is located between the rotating shaft 300 and the guide rail 602, serving as the mounting carrier for the linkage shaft 303 and providing stable support for the rotation of the linkage shaft 303. The incomplete gear 304 only has teeth on some parts, and can achieve discontinuous movement of the base plate 601 through intermittent meshing with the rack 604. The conveyor belt 301 connects the rotating shaft 300 and the linkage shaft 303, and can synchronously transmit the rotational power of the rotating shaft 300 to the linkage shaft 303, so that the two maintain linkage rotation. Its working principle is as follows: When the device is in the punching state, the rotating shaft 300 is stationary, the linkage shaft 303 stops rotating with the rotating shaft 300, the base plate 601 remains stationary under the natural tension of the second spring 603, and the chip collection box 600 is stably positioned below the chip outlet 101 of the current punching die plate 200 to receive waste material; when punching is completed and the next die plate 200 needs to be switched, the motor 700 drives the rotating shaft 300 to rotate, and the rotating shaft 300 drives the linkage shaft 303 to rotate synchronously through the conveyor belt 301, and the incomplete gear 304 on the linkage shaft 303 rotates with the drive shaft 303. When the toothed part of the incomplete gear 304 rotates to mesh with the rack 604, it will push the rack 604 to move the base plate 601 along the guide rail 602 away from the second spring 603, while stretching or compressing the second spring 603. When the toothless part of the incomplete gear 304 rotates to the position of the rack 604, the gear disengages from the rack 604, and the second spring 603 releases its elastic force to move the base plate 601 in the opposite direction to reset. This causes the base plate 601 and the chip collection box 600 to reciprocate during the non-punching stage of mold switching.In this design, the intermittent meshing of the incomplete gear 304 and rack 604, combined with the resetting action of the second spring 603, precisely enables the chip collection box 600 to reciprocate only during the non-punching phase of mold switching. This avoids the chip collection box 600 moving during punching, which affects the accuracy of waste material collection, and also ensures that the chips inside the box are evenly distributed through the reciprocating motion, preventing local accumulation. At the same time, with the linkage between the conveyor belt 301 and the rotating shaft 300, synchronous control can be achieved without an additional power source. The structure is compact and suitable for batch processing needs.

[0034] like Figure 8 As shown, in this embodiment, the base plate 601 is provided with a T-slot 606, and the top of the chip collection box 600 is provided with a T-block 605. The T-block 605 is slidably embedded in the T-slot 606, and one end of the T-slot 606 penetrates the base plate 601, forming an entrance for the T-block 606 to be inserted. It should be noted that the sliding fit structure between the T-slot and the T-block enables the quick assembly and disassembly of the chip collection box 600.

[0035] like Figure 9 As shown, in this embodiment, the T-slot 606 has a groove 609, and the groove 609 has a third spring 608. A stop block 607 is connected to the top of the third spring 608, extending outside the groove 609 and located at the inlet. It should be noted that when installing the chip collection box 600, the stop block 607 is pressed into the groove 609, and then the T-block is aligned with the T-slot inlet and pushed in. After the T-block is fully inside the T-slot, the third spring 608 rebounds, pushing the stop block 607 out of the groove 609. The stop block 607 then locks behind the T-block, preventing the chip collection box 600 from accidentally sliding out. During disassembly, the stop block 607 is manually pressed back into the groove 609, releasing the obstruction to the T-block, allowing the chip collection box 600 to be pulled out along the inlet direction. By adding a groove 609, a third spring 608, and a stop block 607, the structure effectively prevents the chip collection box 600 from slipping out of the T-slot due to vibration and other factors when it moves back and forth with the base plate 601, without affecting the normal loading and unloading of the chip collection box 600. This further improves the stability of the chip collection box 600 installation and ensures that it reliably receives waste materials.

[0036] The working principle of this utility model is as follows: At the start of the operation, the workers can place the rubber parts to be punched on the multiple mold plates 200 on the circular plate 100. After starting the device, the punching machine begins to work: compressed air is introduced into the cylinder 500, the piston rod extends downward, and drives the mounting plate 501, punching column 502 and pressure plate 504 to move down synchronously. The pressure plate 504 first contacts the rubber parts on the mold plate 200. As the mounting plate 501 continues to move down, the first spring 503 is compressed. Under the action of the spring force, the pressure plate 504 tightly presses the rubber parts. Then the punching column 502 passes through the through hole 505 on the pressure plate 504 to punch the rubber parts. The waste generated by punching falls through the mold hole 201 on the mold plate 200 into the chip outlet 101 of the circular plate 100, and finally falls into the stationary chip collection box 600 below for collection. After the rubber part on the current mold plate 200 is punched, the cylinder 500 exhausts air, the piston rod retracts upward, driving the mounting plate 501 and the punching column 502 to move upward. The first spring 503 rebounds and pushes the pressure plate 504 to reset and release the clamping. At the same time, the motor 700 starts, driving the rotating shaft 300 to rotate, which in turn drives the circular plate 100 and multiple mold plates 200 to rotate synchronously, rotating the next mold plate 200 containing the rubber part to be punched to the bottom of the punching machine. During the rotation of the circular plate 100 to switch the mold plate 200, the rotating shaft 300 drives the linkage shaft 303 to rotate synchronously via the conveyor belt 301. The incomplete gear 304 on the linkage shaft 303 rotates accordingly. When the toothed part of the incomplete gear 304 meshes with the rack 604 on the side wall of the base plate 601, it pushes the base plate 601 to move away from the second spring 603 along the guide rail 602 (synchronously stretching / compressing the second spring 603). When the toothless part of the incomplete gear 304 rotates to the position of the rack 604, the gear disengages from the rack 604, and the second spring 603 releases its elastic force to drive the base plate 601 to move in the opposite direction and reset. This process is repeated so that the base plate 601 drives the chip collection box 600 to make short-distance reciprocating movements on the guide rail 602. The waste material collected in the chip collection box 600 is evenly spread out during the shaking, avoiding local accumulation.
