Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape production technology, specifically a perforation device for drip irrigation tape production. Background Technology

[0002] Drip irrigation tape is a water-saving irrigation device that delivers water to the roots of crops through small holes or drippers on capillary tubes with a diameter of about 10mm for localized irrigation. During the production of drip irrigation tape, a punching device is needed to punch holes in its surface. However, existing punching devices require placing the drip irrigation tape on an operating table and then using a cylinder to drive the punching needle to punch holes. This operation is time-consuming and labor-intensive. Furthermore, the punching needle compresses the drip irrigation tape during punching and pulls on the tape when it leaves the tape after punching. This can lead to misalignment of the punched holes, irregular hole shapes, and even tearing. Therefore, there is a need to develop a punching device for drip irrigation tape production that can reduce punching time, improve punching quality, and prevent quality problems caused by tearing at the punched points. Utility Model Content

[0003] To address the above technical problems, this utility model provides a punching device for drip irrigation tape production that can reduce punching time, improve punching quality, and avoid quality problems caused by tearing at the punching point. This solves the problems that existing punching needles squeeze the drip irrigation tape during punching and pull on the drip irrigation tape when they leave the tape after punching, resulting in displacement of the punching position, irregular shape of the punch, or even tearing.

[0004] To solve the above-mentioned technical problems, the present invention provides a punching device for drip irrigation tape production, comprising a base plate, a support leg fixedly connected to the upper end of the base plate, a worktable provided at the upper end of the support leg, a support plate fixedly connected above the worktable, a fixed plate fixedly connected to the upper end of the support plate, a movable sleeve fixedly connected to the lower end of the fixed plate, and a telescopic cylinder fixedly connected to the upper end of the fixed plate. The output end of the telescopic cylinder extends through the fixed plate into the movable sleeve. A rotating shaft is slidably connected inside the movable sleeve. The upper end of the rotating shaft is rotatably connected to the output end of the telescopic cylinder. A spiral groove is formed on the rotating shaft. A slider is fixedly connected to the inner side of the movable sleeve. The slider is slidably connected to the groove. The lower end of the rotating shaft is connected to a punching needle. A first limiting roller group is rotatably connected to the left end of the worktable, a second limiting roller group is rotatably connected to the right end, and a circular hole matching the punching needle is formed through the middle.

[0005] Furthermore, a first support base is fixedly connected to one end of the base plate, and a second support base is fixedly connected to the other end. A storage tray is rotatably connected to the first support base, and a receiving tray is rotatably connected to the second support base. One end of the shaft of the storage tray is fixedly connected to the output end of the storage motor, and one end of the shaft of the receiving tray is fixedly connected to the output end of the receiving motor.

[0006] Furthermore, a waste collection trough is placed on the base plate directly below the circular hole.

[0007] Furthermore, the movable sleeve is symmetrically provided with strip grooves, and the output end of the telescopic cylinder is fixedly connected to a connecting rod. The two ends of the connecting rod pass through the strip grooves and are connected to the movable rod. The two ends of the connecting rod are symmetrically provided with through holes, and the movable rod is slidably connected in the through holes. A spring is sleeved on the movable rod, and the bottom end of the movable rod is fixedly connected to the pressure block. The upper end of the spring is fixedly connected to the connecting rod, and the lower end is fixedly connected to the pressure block.

[0008] Furthermore, the punching pin is detachably connected to the rotating shaft via a mounting plate.

[0009] Furthermore, the first limiting roller group includes two first limiting rollers rotatably connected to the left end of the worktable, and the second limiting roller group includes two second limiting rollers rotatably connected to the right end of the worktable.

[0010] This utility model has the following advantages compared with the prior art:

[0011] This invention utilizes a rotating shaft slidably connected within a movable sleeve, with the rotating shaft and slider working together. When the rotating shaft is pushed downward by the output end of the telescopic cylinder, it rotates and moves downward, reducing the pulling on the drip irrigation tape when the punching needle contacts the tape and when the punching needle leaves the tape after punching. The first and second limiting roller groups at both ends of the worktable allow the drip irrigation tape to stay close to the worktable. By setting pressure blocks, displacement of the drip irrigation tape during punching can be prevented. Attached Figure Description

To improve the stability of the device, a support leg 3 is fixedly connected to the upper end of the base plate 1. A worktable 5 is set on the upper end of the support leg 3. A support plate 2 is fixedly connected above the worktable 5. A fixed plate 4 is fixedly connected to the upper end of the support plate 2. In order to rotate and move the punching needle 25 downward, a movable sleeve 6 is fixedly connected to the lower end of the fixed plate 4, and a telescopic cylinder 7 is fixedly connected to the upper end. The output end of the telescopic cylinder 7 extends through the fixed plate 4 into the movable sleeve 6. A rotating shaft 9 is slidably connected inside. The upper end of the rotating shaft 9 is rotatably connected to the output end of the telescopic cylinder 7. A spiral groove 10 is provided on the rotating shaft 9. A slider 11 is fixedly connected to the inner side of the movable sleeve 6. The slider 11 is slidably connected to the groove 10. The lower end of the rotating shaft 9 is connected to the perforating needle 25. In order to make the drip irrigation tape adhere tightly to the workbench 5, the left end of the workbench 5 is rotatably connected to the first limiting roller group 13, the right end is rotatably connected to the second limiting roller group 14, and a round hole 12 matching the perforating needle 25 is provided through the middle.

[0016] It should be noted that the output end of the telescopic cylinder 7 in this utility model is fixedly connected to a chuck 27, and a groove is provided on the upper part of the rotating shaft 9. The lower end of the chuck 27 is rotatably connected to the inside of the groove.

[0017] In order to store un-drilled drip irrigation tape, collect drilled drip irrigation tape, and facilitate the movement and tensioning of drip irrigation tape during the drilling process, a first support base 15 is fixedly connected to one end of the base plate 1 and a second support base 16 is fixedly connected to the other end. A storage tray 17 is rotatably connected to the first support base 15 and a collection tray 18 is rotatably connected to the second support base 16. One end of the shaft of the storage tray 17 is fixedly connected to the output end of the storage motor 19, and one end of the shaft of the collection tray 18 is fixedly connected to the output end of the collection motor 20.

[0018] To collect the waste material removed from the drip irrigation tape after drilling, a waste collection trough 21 is placed on the base plate 1 directly below the round hole 12.

[0019] To prevent the drip irrigation tape from shifting under the pressure of the punching needle 25 when punching holes, the movable sleeve 6 is symmetrically provided with strip grooves. The output end of the telescopic cylinder 7 is fixedly connected to a connecting rod 8. Both ends of the connecting rod 8 pass through the strip grooves and are connected to the movable rod 22. Both ends of the connecting rod 8 are symmetrically provided with through holes. The movable rod 22 is slidably connected in the through holes. A spring 23 is sleeved on the movable rod 22. The bottom end of the movable rod 22 is fixedly connected to the pressure block 24. The upper end of the spring 23 is fixedly connected to the connecting rod 8, and the lower end is fixedly connected to the pressure block 24.

[0020] To facilitate the disassembly and replacement of the punch 25, the punch 25 is fixedly connected to the mounting plate 26 by threads, and the mounting plate is connected to the bottom of the rotating shaft 9 by bolts.

[0021] To ensure the drip irrigation tape adheres tightly to the workbench 5, the first limiting roller group 13 includes two first limiting rollers rotatably connected to the left end of the workbench 5, and the second limiting roller group 14 includes two second limiting rollers rotatably connected to the right end of the workbench 5. It should be noted that a gap is left between the first limiting roller group 13 and the second limiting roller group 14 in this invention for the drip irrigation tape to pass through.

[0022] The working process of this embodiment is as follows:

[0023] The unperforated drip irrigation tape roll is placed on the storage tray 17. One end of the drip irrigation tape passes through the gap between the two first limiting rollers in the first limiting roller group 13 from the bottom, is pulled upward over the upper surface of the worktable 5, continues to pass through the gap between the two second limiting rollers in the second limiting roller group 14, and then winds downward and is fixed on the collection tray 18. The output end of the telescopic cylinder 7 is controlled to move downward, thereby pushing the rotating shaft 9 to rotate and move downward with the cooperation of the slide groove 10 and the slider 11, until the perforating needle 25 passes through the drip irrigation tape wedge. The tape is inserted into the round hole 12. At the same time, as the telescopic cylinder 7 moves down, it drives the connecting rod 8 to move down as well, until the pressure block 24 contacts the drip irrigation tape and the worktable 5. As the telescopic cylinder 7 continues to move down, the spring 23 tightens continuously, achieving the effect of pressing the drip irrigation tape. After the hole is punched, the telescopic cylinder 7 drives the connecting rod 8 and the rotating shaft 9 to move up. The storage motor 19 and the collection motor 20 work together to collect the punched drip irrigation tape onto the collection tray 18 and move the unpunched part below the punching needle 25.
