Description

Technical Field

[0001] This invention relates to the field of plastic packaging bag technology, specifically to a punching device and punching method for producing plastic packaging bags. Background Technology

[0002] Plastic packaging bags are made from plastic and are used to package various daily necessities. They are widely used in daily life and industrial production, but this convenience brings long-term harm. Most commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and therefore suitable for food packaging.

[0003] Currently, during the production of plastic packaging bags, due to demand, it is necessary to punch holes in the packaging bags. However, existing punching equipment does not have a good fixing structure. To fix the packaging bags, workers usually hold and tighten the packaging bags by hand before using the punching equipment to punch holes. This fixing method greatly increases the labor of workers and also has certain dangers. Summary of the Invention

[0004] The purpose of this invention is to provide a punching device for producing plastic packaging bags, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a punching device for producing plastic packaging bags, comprising a processing table, with support frames fixedly connected to both sides of the upper end of the processing table, a fixed frame fixedly connected to the upper end of the support frames, a punching device fixedly connected to the lower end of the fixed frame, and a fixed platform fixedly connected to the middle of the upper end of the processing table. Clamping mechanisms are installed on both sides of the fixed platform. Through the pressure plate and bottom plate structure set by the clamping mechanism, the plastic packaging bag can be effectively clamped and fixed, ensuring stability and facilitating punching during the punching operation of the plastic packaging bag.

[0006] The clamping mechanism includes an adjusting frame, with an arc-shaped rod slidably connected to the upper middle part of the adjusting frame. A base plate is fixedly connected to the lower end of the adjusting frame near the fixed platform. A pressure plate is provided on the side of the adjusting frame near the fixed platform. By lowering the base plate, the base plate and the pressure plate together clamp the plastic packaging bag, which facilitates the punching operation of the plastic packaging bag.

[0007] In a further embodiment, a movable block is fixedly connected to the pressure plate near the adjustment frame, and an adjustment rod is threadedly connected to the movable block. The adjustment rod and the adjustment frame are rotatably connected. By using the adjustment rod to drive the pressure plate, the clamping can be easily adjusted according to the stacking height of the plastic packaging bags.

[0008] In a further embodiment, the arc-shaped rod is arc-shaped, with its upper end fixedly connected to the support frame, and the side of the arc-shaped rod away from the support frame fixedly connected to the side wall of the fixed platform. The arc-shaped rod serves as a guide to facilitate the movement of the adjustment frame.

[0009] In a further embodiment, a drive mechanism is installed on the side of the clamping mechanism away from the fixed platform. The drive mechanism includes a slide frame, which is rotatably connected to an adjustment frame on the same side. A slide rod is slidably connected to the side of the slide frame away from the fixed platform, and a movable ring is fixedly connected to the side of the slide rod away from the fixed platform. A threaded rod is threadedly connected to the movable ring.

[0010] By using the threaded rod in the drive mechanism to drive the moving ring to move, the moving ring drives the sliding rod and sliding frame to move, thereby driving the adjustment frame to rotate. This allows the adjustment frame to rotate both sides of the plastic packaging bag, resulting in better clamping effect between the base plate and the pressure plate.

[0011] In a further embodiment, the upper end of the threaded rod is rotatably connected to the support frame, and the lower end of the threaded rod passes through the inner wall of the processing table and is fixedly connected to the second bevel gear. The lower end of the second bevel gear meshes with the first bevel gear. One side of the first bevel gear is fixedly connected to a dual-head servo motor via a rotating rod. The dual-head servo motor is fixedly connected to the inner wall of the processing table. By using the dual-head servo motor to drive the first bevel gear and the second bevel gear, the threaded rod can drive the movement of the moving ring, thereby facilitating the movement of the adjustment frame following the trajectory of the arc-shaped rod.

[0012] In a further embodiment, a connecting pipe is fixedly connected to the middle of the processing table near the front of the fixed table. The connecting pipe is connected to a circular groove opened in the fixed table. The lower end of the fixed table receives the collection frame through a snap-fit ​​mechanism. The snap-fit ​​mechanism includes a snap-fit ​​frame, a spring is fixedly connected inside the snap-fit ​​frame, and a snap-fit ​​block is fixedly connected to the side of the spring away from the snap-fit ​​frame. By connecting and fixing the connecting pipe to the collection frame through the snap-fit ​​mechanism, the installation and disassembly of the collection frame can be facilitated, thereby facilitating the cleaning of the recycled waste.

[0013] In a further embodiment, the card block is triangular in shape and engages with the collection frame. Setting the card block in a triangular shape facilitates engagement with the collection frame, thereby facilitating the installation and removal of the collection frame and making it easier to use.

[0014] In a further embodiment, push rods are slidably connected to both sides of the upper end of the collection frame, and push handles are fixedly connected to the push rods on the side away from the collection frame. The push handle and push rod structure facilitates the ejection of the card block from the card frame, making it convenient for the disassembly and installation of the collection frame.

[0015] Preferably, the punching method based on the above-mentioned punching equipment for producing plastic packaging bags includes the following steps;

[0016] A1. Place the stacked plastic bags on the fixed platform, ensuring that both sides of the plastic bags are in contact with the top of the base plate;

[0017] A2. Then rotate the adjusting rod to move the moving block and lower the pressure plate until the pressure plate contacts the plastic packaging bag and the pressure plate and the bottom plate clamp and fix the plastic packaging bag together.

[0018] A3. Start the punching equipment to punch holes in the plastic packaging bags.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] This invention relates to a punching device for producing plastic packaging bags. Through an adjustable rod and a moving block structure, the pressure plate can be lowered and clamped with the base plate to fix the plastic packaging bag. This ensures the plastic packaging bag remains stable and does not shift during punching, preventing the potential dangers of manual clamping and reducing worker labor. A drive mechanism on one side of the adjustable frame allows the frame to follow the trajectory of the curved rod, thereby tilting the plastic packaging bag for better clamping. Furthermore, the quickly detachable collection frame and connecting pipe structure facilitate waste collection and processing, making it convenient and easy to use. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a punching device for producing plastic packaging bags, including a processing table 1. Support frames 2 are fixedly connected to both sides of the upper end of the processing table 1. A fixed frame 6 is fixedly connected to the upper end of the support frame 2. A punching device 7 is fixedly connected to the lower end of the fixed frame 6. A fixed platform 8 is fixedly connected to the middle of the upper end of the processing table 1. Clamping mechanisms 4 are installed on both sides of the fixed platform 8. The clamping mechanism 4 includes an adjusting frame 41. An arc-shaped rod 42 is slidably connected to the upper middle part of the adjusting frame 41. A base plate 46 is fixedly connected to the lower end of the adjusting frame 41 near the fixed platform 8. A pressure plate 45 is provided on the side of the adjusting frame 41 near the fixed platform 8. Through the structure of the pressure plate 45 and the base plate 46 provided by the clamping mechanism 4, the plastic packaging bag can be effectively clamped and fixed, so that the plastic packaging bag is stable and convenient for punching during the punching operation.

[0030] The traditional method of manually clamping and pressing plastic packaging bags is extremely troublesome in actual operation. It is not only very laborious, but also has a certain degree of danger. The pressure plate 45 is fixedly connected to the moving block 44 near the adjusting frame 41. The adjusting rod 43 is threadedly connected to the moving block 44. The adjusting rod 43 and the adjusting frame 41 are rotatably connected.

[0031] Rotate the adjusting rod 43 to move the moving block 44, and the moving block 44 will cause the pressure plate 45 to descend until the pressure plate 45 contacts the plastic bag, and the pressure plate 45 and the bottom plate 46 will clamp and fix the plastic packaging bag together.

[0032] To better secure the plastic packaging bag to the pressure plate 45 and the base plate 46, the arc-shaped rod 42 is arc-shaped. The upper end of the arc-shaped rod 42 is fixedly connected to the support frame 2, and the side of the arc-shaped rod 42 away from the support frame 2 is fixedly connected to the side wall of the fixing platform 8. By setting the arc-shaped rod 42, the adjustment frame 41 can be driven to rotate, so that the force applied by the pressure plate 45 and the base plate 46 to the plastic packaging bag is tilted downward, making the clamping effect more stable.

[0033] Example 2

[0034] Please see Figure 1 , Figure 2 and Figure 3 Further improvements were made based on Example 1:

[0035] To facilitate the adjustment of the adjusting frame 41 in the clamping mechanism 4 to follow the movement of the arc rod 42, a drive mechanism 3 is installed on the side of the clamping mechanism 4 away from the fixed platform 8. The drive mechanism 3 includes a sliding frame 37, which is rotatably connected to the adjusting frame 41 on the same side. The sliding frame 37 is slidably connected to a sliding rod 36 on the side away from the fixed platform 8. The sliding rod 36 is fixedly connected to a moving ring 35 on the side away from the fixed platform 8. A threaded rod 34 is threadedly connected to the moving ring 35. By using the threaded rod 34 in the drive mechanism 3 to drive the moving ring 35 to move, the moving ring 35 drives the sliding rod 36 and the sliding frame 37 to move, thereby driving the adjustment of the adjusting frame 41 to rotate. This allows the adjusting frame 41 to drive the two sides of the plastic packaging bag to rotate, resulting in a better clamping effect between the base plate 45 and the pressure plate 46.

[0036] To reduce manpower costs and make the adjustment of the adjustment frame 41 more convenient, the upper end of the threaded rod 34 is rotatably connected to the support frame 2, and the lower end of the threaded rod 34 passes through the inner wall of the processing table 1 and is fixedly connected to the second bevel gear 33. The lower end of the second bevel gear 33 meshes with the first bevel gear 32. One side of the first bevel gear 32 is fixedly connected to the dual-head servo motor 31 through a rotating rod. The dual-head servo motor 31 is fixedly connected to the inner wall of the processing table 1.

[0037] Start the dual-head servo motor 31, which drives the first bevel gear 32 on both sides to rotate. The first bevel gear 32 drives the second bevel gear 33 to rotate. The second bevel gear 33 drives the threaded rod 34 to rotate, causing the threaded rod 34 to drive the moving ring 35 to descend. The moving ring 35 pulls the adjustment frame 41 on the same side, causing the adjustment frame 41 to descend and move along the trajectory of the arc rod 42. This causes the pressure plate 45 and the bottom plate 46 to clamp the plastic packaging bag at an angle and apply tension, making the plastic packaging bag more stable.

[0038] Example 3

[0039] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 Further improvements were made based on Example 1:

[0040] After punching plastic packaging bags, the excess waste material of the traditional punching equipment 7 will accumulate on the processing table 1, which requires manual cleaning each time, which is very troublesome. The middle of the processing table 1 is connected to the front of the fixed table 8 by a connecting pipe 9. The connecting pipe 9 is connected to the circular groove opened in the fixed table 8. The lower end of the fixed table 8 is connected to the collection frame 10 by a snap-fit ​​mechanism 5. The snap-fit ​​mechanism 5 includes a snap-fit ​​frame 51. A spring 52 is fixedly connected in the snap-fit ​​frame 51. A snap-fit ​​block 53 is fixedly connected to the side of the spring 52 away from the snap-fit ​​frame 51. The snap-fit ​​block 53 is triangular and snaps into the collection frame 10. Push rods 12 are slidably connected to both sides of the upper end of the collection frame 10. A push handle 11 is fixedly connected to the side of the push rod 12 away from the collection frame 10.

[0041] Once the collection is full, push the handle 11 to move the push rod 12, causing the push rod 12 to press the block 53 on the same side. The block 53 is pressed and separated from the collection frame 10 and enters the frame 51. Then, the collection frame 10 can be separated from the connecting pipe 9.

[0042] The connection and fixing of the connecting pipe 9 to the collection frame 10 by the snap-fit ​​mechanism 5 facilitates the installation and disassembly of the collection frame 10, thereby facilitating the cleaning of the recycled waste.

[0043] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
