Description

Technical Field

[0001] This utility model relates to the field of PE bag punching technology, specifically to a PE bag punching device. Background Technology

[0002] A PE bag punching device is a piece of equipment used to punch holes in PE (polyethylene) bags. This device is commonly used in industrial production, such as when manufacturing plastic packaging bags, where holes need to be punched to meet specific functional requirements, such as ventilation and hanging. As shown in Chinese patent application number 202322430899.8, this technical solution uses a fixed frame, a rotating handle, and a screw to drive a pressure plate downwards, thereby positioning and clamping both ends of the PE bag. This prevents the PE bag from shifting or floating due to its lightness during punching, and eliminates the need for manual tightening, reducing safety hazards to workers from the punching head and increasing the stability and safety of the device.

[0003] However, the following problems still exist in this technical solution: the drilling head is fixed on the electric push rod. Since the size of the drilling head is fixed and cannot be disassembled, it can only drill holes of one size and cannot be changed according to the required drilling size, which has certain limitations in use.

Threaded cylinders 602 are movably connected to both sides of the top of the support plate 601 via bearings. The top of the threaded cylinder 602 passes through the workbench 1 and extends beyond the top of the workbench 1. The threaded cylinder 602 is movably connected to the workbench 1 via bearings. A first threaded rod 603 is threadedly connected inside the threaded cylinder 602. A limiting frame 604 is fixedly provided at the top of the first threaded rod 603. The pressing plate 5 is located at the top of the limiting frame 604.

[0036] like Figure 3 As shown, the bottom end of the threaded cylinder 602 passes through the support plate 601 and extends out of the bottom of the support plate 601. A pulley 605 is provided through the bottom end of the threaded cylinder 602. The two pulleys 605 are provided with the same belt 606. A first motor 607 is fixedly provided at the bottom end of one of the threaded cylinders 602. The first motor 607 is fixed to the bottom of the support plate 601 by a bracket.

[0037] Lay the PE bag flat on the top of the workbench 1, and then start the first motor 607. The first motor 607 drives the threaded cylinder 602 to rotate. The two threaded cylinders 602 can rotate simultaneously under the action of the pulley 605 and the belt 606. The rotation of the threaded cylinder 602 drives the first threaded rod 603 to move downward.

[0040] When the PE bag is secured, the third motor 808 is started. The third motor 808 drives the third threaded rod 806 to rotate. The rotation of the third threaded rod 806 drives the second limit block 807 to move. The movement of the second limit block 807 drives the first support column 801 to move. The first support column 801 drives the punching head 3 to move left and right. Then the second motor 805 is started. The second motor 805 drives the second threaded rod 803 to rotate.

The storage box 901 can collect and centrally process the waste generated during drilling, avoiding pollution of the surrounding environment. When the storage box 901 is full, turn the third bolt 907 to turn it out from the fourth threaded hole 905 and the fifth threaded hole 906. Pull the baffle plate 904 to remove it from the front of the support plate 601. Then pull the storage box 901 to remove it from the support plate 601 for easy disposal of the waste inside the storage box 901.

[0043] like Figure 4As shown, the second disassembly mechanism 7 includes a placement groove 701 inside the limiting frame 604. Limiting plates 702 are fixed on both sides of the pressing plate 5. The limiting plates 702 are adapted to the placement groove 701. A third threaded hole 703 is provided on the limiting plate 702. The third threaded hole 703 and the placement groove 701 are connected by the same second bolt 704.

[0044] like Figure 6 As shown, the first disassembly mechanism 4 includes a first threaded hole 401 opened at the top of the punch head 3, and a second threaded hole 402 opened at the bottom of the electric push rod 2. The second threaded hole 402 and the first threaded hole 401 are connected by the same first bolt 403.

[0045] Rotate the second bolt 704 to unscrew it from the third threaded hole 703 and the placement groove 701. Then pull the pressing plate 5 to remove it from the limiting frame 604, making it easy to replace it with a pressing plate 5 of a suitable size for the punching head 3. Then rotate the first bolt 403 to unscrew it from the second threaded hole 402 and the first threaded hole 401, so that the punching head 3 can be removed from the bottom of the electric push rod 2, making it easy to replace it with punching heads 3 of different sizes, so as to punch holes of different sizes and expand the scope of application of this utility model.
