Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, and in particular to a punching device for producing plastic woven bags. Background Technology

[0002] Woven bags are commonly used storage tools in daily life. During the production process of plastic woven bags, a coating process is required. However, this coating process can make the woven bags impermeable to air, which can lead to the rotting of items stored inside. In order to make the plastic woven bags have a certain degree of breathability while ensuring that the items inside are protected from moisture during transportation, loading and unloading, and storage, micropores need to be pierced on the surface of the plastic woven bags.

[0003] Currently, common methods for punching holes in plastic woven bags involve simple mechanical devices, but these often require manual placement and feeding of the bags. Furthermore, the bags may move slightly during punching, which can damage the punching pins or prevent them from detaching properly after punching, thus affecting subsequent processing. To address these issues, this application proposes a punching device for producing plastic woven bags. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a punching device for producing plastic woven bags. This device uses a conveyor motor to drive an active roller in conjunction with a rotating gear to achieve intermittent conveying of the plastic woven bags. A servo motor then controls the punching mechanism to automate the punching operation. The driven roller and damping bearing work together to straighten the woven bags, preventing wrinkles and misalignment. The conveying mechanism and punching mechanism work closely together, with the punching pin surface being smooth and the removal resistance less than the frictional resistance of the damping bearing, ensuring normal removal of the punching pin and preventing damage to the woven bags.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A punching device for producing plastic woven bags includes a processing box containing a plastic woven bag body. Two rotating rods are rotatably connected to the processing box. A drive roller is fixedly connected to the outer wall of each of the two rotating rods, and both drive rollers abut against both ends of the plastic woven bag body. Rotary gears are fixedly connected to the rear ends of each of the two rotating rods, and the two rotating gears mesh with each other. Two driven rollers are rotatably connected to the inner wall of the processing box, located at both ends of the plastic woven bag body, with their outer walls abutting against the outer wall of the plastic woven bag body. Telescopic rods are fixedly connected to the top and bottom of the processing box. Lifting plates are fixedly connected to the output ends of both telescopic rods. A rubber block is fixedly connected to the top of the lower lifting plate, and a punching plate is fixedly connected to the bottom of the upper lifting plate. A moving mechanism is provided between the two lifting plates.

[0007] Preferably, a conveyor motor is fixedly connected to the outer wall of the processing box, the output shaft of the conveyor motor passes through the processing box and is rotatably connected to it, and the output shaft of the conveyor motor is coaxially fixedly connected to the upper rotating rod.

[0008] Preferably, the moving mechanism includes a servo motor disposed on the front of the processing box and fixedly connected thereto. The output shaft of the servo motor passes through the processing box and is rotatably connected thereto. A rotating gear is fixedly connected to the end of the output shaft of the servo motor. The rotating gear meshes with two rack plates. A connecting block is fixedly connected to the rear end of each of the two rack plates. The upper connecting block is fixedly connected to the upper lifting plate, and the lower connecting block is fixedly connected to the lower lifting plate.

[0009] Preferably, both ends of the driven roller are fixedly connected to roller shafts, and each roller shaft is fitted with a damping bearing between itself and the inner wall of the processing box.

[0010] Preferably, each of the two rack plates has a plurality of teeth at its opposite ends that cooperate with the rotating gear.

[0011] Preferably, a plurality of punching pins are fixedly connected to the bottom of the punching plate, and the plurality of punching pins are distributed at equal intervals.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By using a conveyor motor to drive the active roller and the rotating gear, intermittent conveying of plastic woven bags is achieved. Then, a servo motor controls the punching mechanism, eliminating the need for manual placement and conveying, greatly improving production efficiency and meeting the needs of large-scale industrial production.

[0014] 2. The driven roller and the damping bearing work together to straighten the woven bag, avoiding wrinkles and deviation. At the same time, the woven bag is stationary when punching holes, and with the support of the rubber block, it ensures that the punching position is accurate and the depth is consistent, thus improving product quality.

[0015] 3. The conveying mechanism and the punching mechanism work closely together. The surface of the punching nail is smooth and the resistance to removal is less than the frictional resistance of the damping bearing, which ensures that the punching nail is pulled out normally, prevents damage to the woven bag, makes the whole processing flow smooth and efficient, and reduces the defect rate.

[0016] In summary, the intermittent conveying of plastic woven bags is achieved by using a conveyor motor to drive the active roller in conjunction with a rotating gear. Then, a servo motor controls the punching mechanism to achieve automated punching operations. The driven roller and the damping bearing work together to straighten the woven bags, preventing wrinkles and misalignment. The conveying mechanism and the punching mechanism work closely together, and the surface of the punching nail is smooth with less resistance to disengagement than the frictional resistance of the damping bearing, ensuring that the punching nail can be pulled out normally and preventing damage to the woven bags.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3A punching device for producing plastic woven bags includes a processing box 1, in which a plastic woven bag body 4 is conveyed. Two rotating rods 2 are rotatably connected to the processing box 1. A conveying motor 5 is fixedly connected to the outer wall of the processing box 1, providing driving power for conveying the plastic woven bag body 4. The output shaft of the conveying motor 5 passes through the processing box 1 and is rotatably connected to it. The output shaft of the conveying motor 5 is coaxially fixedly connected to the upper rotating rods 2. A drive roller 3 is fixedly connected to the outer wall of each of the two rotating rods 2. The two drive rollers 3 are abutted against both ends of the plastic woven bag body 4. The friction generated by the rotation of the two drive rollers 3 abuts against both ends of the plastic woven bag body 4, thereby driving the bag. The plastic woven bag body 4 moves, and the rear ends of the two rotating rods 2 are fixedly connected to rotating gears 6. The two rotating gears 6 mesh with each other, so that the two driving rollers 3 can rotate synchronously, ensuring the stability of the conveying of the plastic woven bag body 4. The inner wall of the processing box 1 is rotatably connected to two driven rollers 7. The two driven rollers 7 are located at both ends of the plastic woven bag body 4, and the outer wall of the driven rollers 7 abuts against the outer wall of the plastic woven bag body 4. The driven rollers 7 assist the driving rollers 3 in conveying the plastic woven bag body 4. Roller shafts are fixedly connected to both ends of the driven rollers 7. A damping bearing 8 is installed between each roller shaft and the inner wall of the processing box 1. The damping bearing 8 restricts the random rotation of the driven rollers 7 and straightens the plastic woven bag body 4.

[0023] Telescopic rods 9 are fixedly connected to the inner top and bottom of the processing box 1. Lifting plates 10 are fixedly connected to the output ends of the two telescopic rods 9. A rubber block 11 is fixedly connected to the top of the lower lifting plate 10. In this application, the rubber block 11 is detachable by bolt installation, and the rubber block 11 can be replaced periodically to ensure normal function. The rubber block 11 supports the plastic woven bag body 4. A perforating plate 12 is fixedly connected to the bottom of the upper lifting plate 10. Multiple perforating nails 13 are fixedly connected to the bottom of the perforating plate 12. The multiple perforating nails 13 are distributed at equal intervals. The perforating nails 13 are used to perform perforation operations on the plastic woven bag body 4.

[0024] A moving mechanism is provided between the two lifting plates 10. The moving mechanism includes a servo motor 14 fixedly connected to the front of the processing box 1. The output shaft of the servo motor 14 passes through the processing box 1 and is rotatably connected to it. A rotating gear 15 is fixedly connected to the end of the output shaft of the servo motor 14. The rotating gear 15 meshes with two rack plates 16. The rotating gear 15 and the rack plates 16 cooperate with each other to convert the rotational motion of the servo motor 14 into the linear motion of the rack plates 16. The opposite ends of the two rack plates 16 are provided with multiple teeth that cooperate with the rotating gear 15. The rear ends of the two rack plates 16 are fixedly connected to connecting blocks 17. The upper connecting block 17 is fixedly connected to the upper lifting plate 10, and the lower connecting block 17 is fixedly connected to the lower lifting plate 10, so as to realize the drive control of the lifting plate 10 by the servo motor 14.

[0025] In this invention, the plastic woven bag body 4 is conveyed by the cooperation of a pair of active rollers 3 and a pair of driven rollers 7. The pair of active rollers 3 provide power for the conveying of the plastic woven bag body 4, and the cooperation of the driven rollers 7 and the telescopic rod 9 can straighten the conveyed plastic woven bag body 4 to facilitate subsequent punching operations. When the conveying motor 5 is started, its output shaft drives the upper rotating rod 2, active rollers 3, rotating gear 6, lower rotating gear 6, rotating rod 2, and active rollers 3 to rotate, allowing for intermittent conveying of the plastic woven bag body 4 (5 seconds of conveying followed by 5 seconds of rest). When the plastic woven bag body 4 stops conveying, the servo motor 14 starts, and its output shaft drives the rotating gear 15 to rotate counterclockwise, causing the rack plates 16, connecting blocks 17, and lifting plates 10 on both sides to move. During this process, the telescopic rod 9 extends and retracts accordingly, and the lifting plates 10 on both sides move accordingly. The relative movement punches holes in the stationary plastic woven bag body 4. The rubber block 11 supports the plastic woven bag body 4. Multiple punching nails 13 move down to punch holes in the plastic woven bag body 4, and finally the multiple punching nails 13 are inserted into the surface of the rubber block 11 to complete the punching. After the punching is completed, the servo motor 14 starts in reverse so that the lifting plates 10 on both sides move away from each other and no longer contact the plastic woven bag body 4. At this time, the plastic woven bag body 4 continues to be conveyed, and the punching operation of the plastic woven bag body 4 is completed. In this application, the circumference of the rotation of the two active rollers 3 in one process is the length of one plastic woven bag body 4, which can punch holes in one plastic woven bag body 4. The surface of the punching nail 13 is smooth with a low coefficient of friction, and the frictional resistance of the punching nail 13 detaching from the plastic woven bag body 4 is less than the frictional resistance of the damping bearing 8, ensuring that the punching nail 13 can be pulled out of the plastic woven bag body 4 normally.
