[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-5 The shown is a punching device for bag production, comprising:

[0026] Drilling equipment and mold frame 1 that is snapped into the inside of the bag;

[0027] The mold frame 1 has a positioning hole 2 corresponding to the opening position of the bag. The punching equipment includes a housing 3. A fixed connecting seat 4 is fixed on one side of the bottom of the housing 3. A support seat 5 is fixed on the side of the fixed connecting seat 4 away from the housing 3. A movable connecting seat 6 is movably arranged at the bottom of the housing 3. A punch 7 for punching is fixed on the side of the movable connecting seat 6 away from the housing 3. A flat pushing component 8 for moving the movable connecting seat 6 is provided inside the housing 3.

[0028] The outer side of the punch 7 is also provided with a positioning tube 9 for precise positioning;

[0029] With the cooperation of the flat push component 8, the movable connecting seat 6 can be moved easily. The movable connecting seat 6 drives the punch 7 to move closer to the support seat 5, thereby extruding and punching the bag. Before punching, the mold frame 1 is placed inside the bag, and the punching equipment is aligned with the positioning hole 2, which can accurately punch the holes on the bag. At the same time, the equipment has a simple structure and low cost, reducing the procurement cost of small enterprises. It is also convenient for manual operation and is portable.

[0030] Among them, such as Figure 3 As shown:

[0031] The push assembly 8 includes a screw 81 rotatably connected to the inner cavity of the equipment housing 3 via a bearing. A drive motor 82 is fixed to one end of the equipment housing 3. The output end of the drive motor 82 passes through the inner cavity of the equipment housing 3 and is fixedly connected to one end of the screw 81. A moving block 83 is threadedly connected to the outer side of the screw 81. The moving block 83 slides against the inner cavity of the equipment housing 3. The bottom of the moving block 83 passes through the outer side of the equipment housing 3 and is fixedly connected to the movable connecting seat 6. The drive motor 82 drives the screw 81 to rotate, and then the screw 81 rotates to translate the moving block 83. The moving block 83 drives the movable connecting seat 6 on the outer side to move, adjusting the distance between the punch 7 and the support seat 5, so that the opening device can be easily locked on the outside of the bag for opening.

[0032] Furthermore, such as Figure 4 As shown:

[0033] The positioning tube 9 is slidably sleeved on the outside of the punch 7. A limiting groove 10 is opened on the positioning tube 9. The movable connecting seat 6 is located in the limiting groove 10. A limiting ring 11 sleeved on the outside of the positioning tube 9 is fixed on the outside of the movable connecting seat 6. A fixing ring 12 is fixed on the outside of the positioning tube 9. A support spring 13 is fixed between the fixing ring 12 and the limiting ring 11. The support spring 13 is installed through the fixing ring 12 and the limiting ring 11 to ensure that the positioning tube 9 covers the punch 7 inside without external interference, so as to facilitate the docking of the positioning tube 9 and the positioning ring 14 and accurately position the punch 7.

[0034] Preferred, such as Figure 5 As shown:

[0035] Multiple sets of positioning rings 14 are fixed on the inner side wall of the mold frame 1. The positioning rings 14 correspond one-to-one with the positioning holes 2, and the inner diameter of the positioning rings 14 is the same as the outer diameter of the positioning tube 9. By fixing the positioning rings 14 on the inner side wall of the mold frame 1, it is convenient to accurately position the punch 7 after the positioning tube 9 is connected to the positioning rings 14, so as to prevent the punch 7 from shifting during punching and causing the punching position deviation.

[0036] It is worth noting that, such as Figure 2 As shown:

[0037] Both the fixed connecting seat 4 and the movable connecting seat 6 are fixed with support plates 15 on their outer sides. One end of the support plate 15 abuts against the outer side of the equipment housing 3. The support plate 15 facilitates the reinforcement and support of the fixed connecting seat 4 and the movable connecting seat 6, preventing the fixed connecting seat 4 and the movable connecting seat 6 from bending under force when the punch 7 and the support seat 5 clamp the bag.

[0038] In a further preferred embodiment, such as Figure 3 As shown:

[0039] A through hole 16 is provided at the center of the support base 5. The diameter of the through hole 16 is the same as the outer diameter of the punch 7. By providing a through hole 16 on the support base 5, the punch 7 can pass through the bag and cut the bag material at the punching position.

[0040] In addition, such as Figure 3 As shown:

[0041] The equipment housing 3 is provided with a handle 17, and a control switch 18 is provided on the handle 17. A control circuit board is provided inside the equipment housing 3, and the control switch 18 and the drive motor 82 are electrically connected to the control circuit board. The handle 17 facilitates the operator's control of the drilling equipment, and the control switch 18 can control the start of the drive motor 82.

[0042] In practical use, the mold frame 1 is placed inside the bag to support it. The support seat 5 and punch 7 on the punching device are then placed on the inner and outer sides of the bag, with the punch 7 placed inside the bag. The positioning tube 9 is engaged with the positioning ring 14. Then, the drive motor 82 is controlled by the control switch 18. The drive motor 82 drives the screw 81 to rotate. The rotation of the screw 81 causes the moving block 83 to move horizontally on the screw 81. At the same time, the moving block 83 drives the movable connecting seat 6 and the punch 7 to push horizontally on the equipment housing 3, shortening the distance between the punch 7 and the support seat 5. When the support seat 5 is close to the outside of the bag, the punch 7 moves inside the positioning tube 9 and penetrates the positioning hole 2 inside the positioning ring 14 to contact the bag. Then, the punch 7 penetrates the bag and punches a hole at the punching position. Then, the control switch 18 is controlled to reverse the drive motor 82, causing the punch 7 to separate from the support seat 5, making it convenient for the punching device to perform punching operations along different positioning holes 2 on the mold frame 1.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
