Description

Technical Field

[0001] This utility model relates to the field of packaging bag processing technology, and in particular to a packaging bag making device. Background Technology

[0002] In the packaging and bagging production process, the raw film needs to undergo multiple processing steps. Traditional production methods often require multiple independent machines to complete operations such as unwinding, correction, cutting, folding, edge melting, and rewinding. The raw film needs to be transferred and connected manually between the machines, which not only consumes a lot of labor costs, but also has problems such as low production efficiency, poor connection between processes, and difficulty in guaranteeing processing accuracy.

[0003] Especially in the processes of cutting the tear line, folding, and fusing the edges of the raw film, manual operation can easily lead to inaccurate tear line cutting, uneven folding of the raw film, and weak fusing, thus affecting the product quality of the packaging bags. In addition, multiple independent machines occupy a large area, increasing the cost of production space and hindering enterprises from achieving large-scale and automated production. To address the problems existing in the prior art, this application proposes an integrated packaging bag making device that integrates multiple processing steps on the same equipment, realizing fully automated processing of raw material film from unwinding to rewinding, effectively improving production efficiency and product quality, and reducing production costs. Utility Model Content

[0004] The main purpose of this utility model is to provide a packaging bag making device to solve the problems of scattered equipment, excessive manual intervention, low production efficiency, unstable product quality, and large footprint in the traditional packaging bag production process. It aims to realize the automation and integration of packaging bag production, improve production efficiency and product quality, and reduce production costs and site occupation costs.

[0005] To achieve the above objectives, this utility model proposes a packaging bag making device, comprising: A first frame and a second frame, wherein the first frame is provided with an unwinding roller and the first frame and the second frame are respectively provided with tensioning roller groups; A cutting structure includes a connecting frame and a cutting tool. The two ends of the connecting frame are fixedly connected to the first frame and the second frame, respectively. A sliding block is provided on the connecting frame, and the cutting tool is mounted on the sliding block. A pushing member is provided on the connecting frame, and the output end of the pushing member is connected to the sliding block. The edge-sealing machine is located on one side of the second frame. The second frame is equipped with a folding plate. The raw material film is released from the unwinding roller and passes through the tensioning roller group on the first frame and the second frame in sequence. The cutting blade cuts the easy-tear line of the raw material film. After passing through the folding plate, it is folded in half. The folded raw material film is then fused and sealed by the edge-sealing machine.

[0006] Optionally, the first frame is provided with a support, and the support is provided with three correction rollers. After the raw material film is released from the unwinding roller, it passes through the correction rollers and is corrected by an automatic correction mechanism.

[0007] Optionally, the connecting frame is provided with a sliding groove, and the sliding block includes a connecting part and a sliding part. The connecting part and the sliding part are perpendicularly connected. The sliding part is installed in the sliding groove and can move along the sliding groove.

[0008] Optionally, the connecting frame is provided with a mounting platform, the pusher is mounted on the mounting platform, and the output end of the pusher passes through the mounting platform and is connected to the connecting part.

[0009] Optionally, the top of the second frame is provided with a connecting column, and the folding plate is installed on the connecting column and inclined downward.

[0023] This utility model proposes a packaging bag making device 100.

[0024] Please see Figures 1-3 In one embodiment of the present invention, the packaging bag making device 100 includes a first frame 10, a second frame 20, a cutting structure, a third frame 40, and a sealing edge machine 41.

[0025] The first frame 10 is equipped with an unwinding roller 11 for holding the raw material film roll, enabling continuous unwinding of the raw material film. Simultaneously, the first frame 10 also has a support 12, which is equipped with three correction rollers 13. After the raw material film is released from the unwinding roller 11, it first passes through the correction rollers 13 for correction. The three correction rollers 13 cooperate with an automatic correction mechanism to correct the deviation of the raw material film during unwinding, effectively correcting any offset that occurs during the unwinding process and ensuring the flatness and accuracy of the raw material film in subsequent processing. Furthermore, the first frame 10 is equipped with a tensioning roller group 14 to adjust the tension of the raw material film during transport, preventing the raw material film from becoming loose or wrinkled due to insufficient tension, or from breaking due to excessive tension.

[0026] It should be noted that automatic web guiding mechanisms include electromechanical mechanisms commonly found in existing technologies, which include web guiding sensors (such as photoelectric, ultrasonic, and CCD sensors), controllers, servo / stepper motors, and actuators (ball screws and synchronous belts). These mechanisms can detect object offset in real time and automatically adjust their position, ensuring production or operational accuracy.

[0027] The second frame 20 is also equipped with a tension roller assembly 14, which works in conjunction with the tension roller assembly on the first frame 10 to maintain stable tension of the raw material film throughout the entire conveying path. A connecting column 22 is located at the top of the second frame 20, and a folding plate 21 is mounted on the connecting column 22. The folding plate 21 is inclined downwards to fold the raw material film conveyed by the tension roller assembly 14.

[0028] It should be noted that the folding plate 21 is triangular in shape with its pointed corners facing downwards. In order to ensure the structural stability of the folding plate 21, the second frame 20 is provided with a support rod. The support rod 23 abuts against the lower end of the folding plate 21 and supports the folding plate 21 to prevent the folding plate 21 from deforming due to the pressure of the raw material film during long-term use.

[0029] Additionally, the second frame 20 is equipped with a merging roller group 24, which is located below the end of the folding plate 21. After the folded raw material film is output from the end of the folding plate 21, the center of the raw material film passes through the tip of the folding plate 21, and the gap between the tip of the folding plate 21 and the merging roller group 24 is aligned. After the raw material film enters the merging roller group 24, the squeezing action of the merging roller group 24 makes the folded edge of the raw material film fit more closely, preparing it for the subsequent edge-melting process. At the same time, a tensioning roller shaft 25 is provided on one side of the merging roller group 24 to further adjust the tension of the folded raw material film, ensuring that the raw material film can be stably conveyed to the edge-melting machine 41.

[0030] The cutting structure includes a connecting frame 30 and a cutting tool 301. The two ends of the connecting frame 30 are fixedly connected to the first frame 10 and the second frame 20, respectively, allowing the cutting structure to be stably erected between the first frame 10 and the second frame 20. The connecting frame 30 has a sliding groove 36, within which a sliding block 31 is installed. The sliding block 31 includes a connecting part 33 and a sliding part 32, with the connecting part 33 and the sliding part 32 perpendicularly connected. The sliding part 32 is installed in the sliding groove 36 and can move along the sliding groove 36. The cutting tool 301 is installed at the bottom of the sliding part 32. As the sliding block 31 moves, the cutting tool 301 can complete easy-tear line cutting at different positions. The cutting tool 301 is a laser cutting tool.

[0031] To drive the movement of the sliding block 31, a mounting platform 35 is provided on the connecting frame 30. A pusher 34 is mounted on the mounting platform 35, and the output end of the pusher 34 passes through the mounting platform 35 and connects to the connecting part 33 of the sliding block 31. The pusher 34 can be an electric push rod. Through the extension and retraction of the pusher 34, the sliding block 31 can be driven to reciprocate along the sliding groove 36, thereby driving the cutting tool to complete the cutting operation of the easy-tear lines at different positions of the raw material film. Furthermore, the position of the easy-tear lines can be controlled by adjusting the extension and retraction stroke of the pusher 34 according to actual production needs.

[0032] The third frame 40 is located at the rear end of the second frame 20. The edge-sealing machine 41 is installed on the third frame 40 and is used to fuse and seal the folded raw material film after it has been processed by the combined roller group, melting and connecting the folded edges of the raw material film to form the side structure of the packaging bag. The front end of the edge-sealing machine 41 has a constant tension film clamping drive traction, and the rear end has a rigid-flexible film clamping mechanism, which can maintain a constant tension of the raw material film throughout the process and prevent the raw material film from becoming loose, wrinkled, stretched, misaligned, or broken. The third frame 40 is also equipped with a winding roller 42, which winds up the raw material film after the edge sealing is completed to form a roll of semi-finished packaging bag for subsequent cutting, sealing and other further processing steps.

[0033] It should be noted that the edge melting machine 41 can be a hot pressing edge melting machine, which uses heated rollers or heating plates to squeeze and heat the material edges, causing the material edges to melt and bond together.

[0034] Workflow: The raw material film roll is mounted on the unwinding roller 11 of the first frame 10. The raw material film is released from the unwinding roller 11 and first passes through three straightening rollers 13 on the support 12 for straightening treatment to correct the offset of the raw material film. After straightening, the raw material film enters the tensioning roller group 14 of the first frame 10. Under the action of the tensioning roller group 14, the tension is adjusted and then conveyed to the area below the cutting structure. The pusher 34 on the connecting frame 30 drives the sliding block 31 to move along the sliding groove 36, which drives the cutting blade 301 to perform easy-tear line cutting on the raw material film. The raw material film with the easy-tear line cut is then conveyed to the second frame 20. After further tension adjustment of the tension roller group, the raw material film enters the folding plate 21. Under the action of the folding plate 21, the raw material film is folded in half. The folded raw material film is output from the end of the folding plate 21 and enters the merging roller group 24 located below. Under the squeezing action of the merging roller group 24, the folded edges are glued together. After the glued raw material film passes through the tension roller shaft 25 and the tension is adjusted again, it is conveyed to the edge-sealing machine 41 on the third frame 40. The edge-sealing machine 41 fuses and seals the folded edges of the raw material film. The raw material film with the fused and sealed edges is finally wound up by the winding roller 42 on the third frame 40 to form a roll of packaging bag semi-finished product, completing the entire bag making process.

[0035] This application integrates the first frame 10, the second frame 20, the third frame 40, and various functional components to achieve automated continuous processing of raw material film from unwinding, correction, easy-tear wire cutting, folding, edge melting to rewinding. This reduces manual intervention, lowers labor costs, and avoids damage and errors to the raw material film during manual handling, thereby improving production efficiency and product quality. The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
