Description

Technical Field

[0001] This utility model belongs to the field of plastic packaging product processing technology, specifically a high-efficiency cutting device for plastic packaging products. Background Technology

[0002] Plastic packaging products, due to their advantages such as light weight, low cost, and good barrier properties, have been widely used in the food, pharmaceutical, electronics, and logistics industries, resulting in high-volume, multi-specification, and high-precision production. With the surge in consumer demand for packaging (such as express delivery bags for e-commerce logistics and vacuum packaging bags for the food industry), plastic packaging manufacturers are generally facing pressure to achieve mass production and continuous operation. Traditional cutting equipment relies heavily on manual positioning and single-machine, single-specification operation, with hourly capacity only meeting the needs of small and medium-sized orders. This makes it difficult to meet the efficiency requirements of large enterprises' "24-hour uninterrupted production lines," necessitating equipment upgrades to reduce costs and increase efficiency.

[0003] Meanwhile, a cutting device for plastic packaging products, with application number CN202323295787.2, includes a base and a cutting mechanism. The cutting mechanism is arranged above the base and includes a conveying component, an adjusting component, a cutting tool component, and a fixing component. The conveying component is arranged at the top of the base, the adjusting component is arranged above the conveying component, the cutting tool component is installed at the bottom of the adjusting component, and the fixing component is arranged on one side of the cutting tool component. The conveying component includes a conveyor belt, a support frame, a conveyor motor, and a sensor. The conveyor belt is installed on the surface of the base, the support frame is installed at the top of the base, the conveyor motor is arranged on one side of the conveyor belt, and the sensor is installed on the outside of the support frame.

[0004] However, the following problems were found in the implementation of the relevant technology: the manual marking or fixed block positioning is easily affected by operating experience and visual deviation, resulting in inconsistent workpiece cutting starting points; the fixed blocks cannot be flexibly adjusted, and bolts need to be disassembled and recalibrated when changing production, which is time-consuming and prone to calibration errors, making the deviation problem more prominent, the defect rate remains high, and the workpiece is prone to wrinkling, resulting in unstable cutting quality. Plastic packaging has the characteristics of high flexibility and easy wrinkling, and the existing equipment lacks an effective flattening mechanism. During the conveying and cutting process, the workpiece is prone to wrinkling due to uneven tension and uneven conveyor rollers.

[0005] Therefore, we propose a high-efficiency cutting device for plastic packaging products. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a high-efficiency cutting device for plastic packaging products, which has the advantages of obtaining uniform cutting length, achieving the same cutting results, and flattening the workpiece to prevent wrinkles and improve processing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency cutting device for plastic packaging products, comprising a conveying mechanism, a cutting table installed on one side of the conveying mechanism, a cutting mechanism installed on the cutting table, a positioning groove provided on the cutting table, a sliding block slidably connected in the positioning groove, a positioning plate fixedly connected to the left side of the upper surface of the sliding block, a bolt fixedly connected to the right side of the upper surface of the sliding block, a threaded sleeve threadedly connected to the bolt, a support frame fixedly connected to the outer surface of the conveying mechanism, a motor fixedly connected to the inner top surface of the support frame, a lead screw fixedly connected to the output end of the motor, a threaded block threadedly connected to the lead screw, a fixing block fixedly connected to the inner top surface of the support frame, a telescopic connecting rod installed on the threaded block and the fixing block, an mounting frame installed at the other end of the telescopic connecting rod, and a conveying roller installed inside the mounting frame.

[0008] Preferably, the cutting mechanism includes a cutting machine and a positioning structure.

[0009] Preferably, the fixing block is rotatably connected to the lead screw.

[0010] Preferably, a sliding rod is fixedly connected to the outer surface of the fixing block, and the sliding rod is slidably connected to the threaded block.

[0011] Preferably, a cover plate is fixedly connected to the positioning groove, the cover plate is provided with a slot, the slot is slidably connected to the bolt, and a control handle is fixedly connected to the upper surface of the threaded sleeve.

[0012] Preferably, the front side of the positioning groove is provided with a scale.

[0013] Preferably, the support frame is provided with a sliding groove, and sliders are fixedly connected to both sides of the mounting frame, with the sliders slidably connected to the sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model utilizes the cooperation of a positioning groove, sliding block, positioning plate, cover plate, bolt, and threaded sleeve. One end of the workpiece rests against the positioning plate, which is the cutting length, thus obtaining a uniform cutting length. This ensures consistent cutting results, reduces dimensional deviations, and allows for convenient adjustment of the positioning plate's position. This enables rapid positioning, reduces manual measurement and tool setting time, improves processing efficiency, and enhances positioning accuracy and stability.

[0015] 2. This utility model, through the cooperation of a support frame, motor, lead screw, threaded block, fixing block, telescopic connecting rod, mounting frame and conveyor roller, can flatten the workpiece and prevent wrinkles. At the same time, the height can be adjusted according to the thickness of the workpiece, eliminating wrinkles and irregular ripples in the material before cutting. The flattened workpiece is more likely to produce neat and repeatable cuts, and can reduce debris and burrs, reduce thickness variations caused by material wrinkling, reduce kerf and finished product size deviations, and improve cutting quality and consistency.

The cutting mechanism 3 includes a cutting machine and a positioning structure. The positioning mechanism is a telescopic rod driven by a cylinder. A pressure plate is fixed at the lower end of the telescopic rod, and the two sides of the cutting line are fixed by the pressure plate. A positioning groove 4 is provided on the cutting table 2, and a sliding block 5 is slidably connected in the positioning groove 4. A positioning plate 6 is fixedly connected to the left side of the upper surface of the sliding block 5, and a positioning plate 6 is fixedly connected to the right side of the upper surface of the sliding block 5. There is a bolt 8, and a threaded sleeve 9 is threadedly connected to the bolt 8. A support frame 10 is fixedly connected to the outer surface of the conveying mechanism 1. A motor 11 is fixedly connected to the inner top surface of the support frame 10. A lead screw 12 is fixedly connected to the output end of the motor 11. A threaded block 13 is threadedly connected to the lead screw 12. A fixing block 14 is fixedly connected to the inner top surface of the support frame 10. A telescopic connecting rod 15 is installed on the threaded block 13 and the fixing block 14. A mounting frame 16 is installed at the other end of the telescopic connecting rod 15. A conveying roller 17 is installed inside the mounting frame 16. The conveying roller 17 is driven by a motor.

[0020] Specifically, the fixed block 14 is rotatably connected to the lead screw 12.

[0021] Furthermore, a slide rod 19 is fixedly connected to the outer surface of the fixing block 14, and the slide rod 19 is slidably connected to the threaded block 13.

[0022] Furthermore, a cover plate 7 is fixedly connected to the positioning groove 4, and a slot is provided on the cover plate 7. The slot is slidably connected to the bolt 8, and a control handle is fixedly connected to the upper surface of the threaded sleeve 9.

[0023] It is worth noting that the front of the positioning groove 4 is provided with a scale 20, which is used to visually display the cutting length.

[0024] It is worth noting that the support frame 10 is provided with a sliding groove 18, and the two sides of the mounting frame 16 are fixedly connected with sliders. The sliders are slidably connected to the sliding groove 18 to support the sliding of the mounting frame 16.

The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0026] Working principle: In use, first rotate to loosen the threaded sleeve 9, then manually push the positioning plate 6. The positioning plate 6 slides in the positioning groove 4 through the sliding block 5, and the cutting length is accurately displayed through the scale 20. Move the positioning plate 6 to the corresponding scale 20 position, then rotate the threaded sleeve 9. The threaded sleeve 9 rotates on the bolt 8 and moves closer to the sliding block 5 through the action of the thread, thereby clamping the cover plate 7 with the sliding block 5 to fix the position of the sliding block 5, and thus fixing the position of the positioning plate 6. Then, the plastic packaging product is conveyed through the conveying mechanism 1. When passing the support frame 10, the mounting frame 16 is pre-adjusted according to the plastic packaging product. The height of the conveyor roller 17 is determined by the motor 11 driving the lead screw 12 to rotate. The threaded block 13 moves linearly on the lead screw 12 through the action of the thread, and the linear movement of the threaded block 13 drives one corner of the telescopic connecting rod 15 to move, thereby adjusting the extension length of the telescopic connecting rod 15. Then, the telescopic connecting rod 15 pushes out of the mounting frame 16 and the conveyor roller 17, and then the conveyor roller 17 and the conveying mechanism 1 convey the plastic packaging product and flatten it. Then, the flattened plastic packaging product is conveyed to the cutting table 2 through the conveying mechanism 1, and one end of the plastic packaging product abuts against the positioning plate 6, which is the cutting size. Then, the cutting mechanism 3 performs the cutting.
