Description

Technical Field

[0001] This utility model relates to the field of woven bag processing technology, specifically a positioning and cutting machine for producing polymer woven bags. Background Technology

[0002] Woven bags, also known as snake-skin bags or plastic woven bags, are packaging materials made from chemical plastic raw materials such as polypropylene (PP) and polyethylene (PE). They are made by extruding and stretching into flat filaments, and then weaving, braiding, and bag making processes. In order to meet the packaging needs of different capacities, woven bags often need to be cut during the production process.

[0003] A search revealed patent application CN202221673764.3, which discloses a cutting device for the production of plastic woven bags. The device includes a cutting support plate, a support column, a cutting opening, a lifting displacement adjusting rod, an upper support plate, a cutting adjusting clamping rod, a cutting clamping fixing plate, a conventional edge clamping device, and an adjustable displacement cutting device. The support column is mounted on the cutting support plate, the cutting opening is mounted on the cutting support plate, the lifting displacement adjusting rod is mounted on the cutting support plate, the upper support plate is mounted on the lifting displacement adjusting rod, the cutting adjusting clamping rod is mounted on the upper support plate, and the cutting clamping fixing plate is mounted on the cutting adjusting clamping rod and positioned closer to the cutting support plate. This utility model belongs to the field of woven bag processing technology, specifically a cutting device for the production of plastic woven bags. It effectively solves the problem of unstable clamping and positioning during cutting of woven bags, leading to poor cutting results or even incomplete cutting. This problem is overcome by setting up a double clamping device in conjunction with a movable cutting device.

[0004] However, this patent has its shortcomings. In this woven bag cutting device, multiple cutting and clamping plates located on both sides of the cutting blade are fixedly installed on the upper support plate by multiple cutting adjustment and clamping rods. The spacing between the multiple cutting and clamping plates cannot be adjusted, so it cannot adapt to the clamping and clamping requirements of woven bags of different widths. The applicability of the equipment is low. At the same time, during the cutting process, the operator needs to operate the lifting displacement adjustment rod and the cutting adjustment and clamping rod switch to control the clamping of the cutting and clamping plates and the lifting and cutting operation of the cutting blade. The operation steps during the cutting process are relatively cumbersome and can easily affect the processing efficiency.

[0005] To address this, we propose a positioning and cutting machine for the production of polymer woven bags. Utility Model Content

[0013] Optionally, a PLC controller is fixedly installed at the bottom front end of the frame, which facilitates the control of the equipment during operation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Through the coordinated operation of the movable seat, fixed seat, limiting frame, distance scale, electric push rod, first positioning pressure plate, second positioning pressure plate, movable beam, threaded rod, motor, spring, sliding plate, and connecting rod, the distance between the first and second positioning pressure plates can be adjusted according to usage needs.

The tops of multiple springs 18 are fixedly installed inside the movable seat 5 and the fixed seat 6, respectively. The bottom ends of multiple sliding plates 19 are all fixedly installed with connecting rods 20. The bottom ends of multiple connecting rods 20 extend out of the fixed seat 6 and the movable seat 5 and are respectively fixedly installed on the first positioning pressure plate 11 and the second positioning pressure plate 12. The lifting seat 2 is provided with a mounting groove 16 located on the left side of the hot cutting knife 13. A threaded rod 15 is rotatably connected in the mounting groove 16. A movable beam 14 is threaded on the threaded rod 15. The front and rear ends of the movable beam 14 extend out of the mounting groove 16 and are fixedly installed on the corresponding movable seat 5.

[0022] A motor 17 is fixedly installed on the left end of the lifting seat 2. The output end of the motor 17 is fixedly installed on the threaded rod 15. The rotation of the threaded rod 15 by the motor 17 facilitates the use of this equipment. A cutting groove 21 is opened at the bottom of the frame 1 corresponding to the hot cutting knife 13. The cutting groove 21 and the hot cutting knife 13 facilitate the cutting of woven bags. A limit frame 7 is set at the right side of the cutting groove 21 at the bottom of the frame 1. Distance scales 8 are set at the front and rear ends of the frame 1 corresponding to the limit frame 7. Electric push rods 9 are fixedly installed at the lower part of the distance scales 8 at the front and rear ends of the frame 1. The output ends of the two electric push rods 9 are fixedly installed on the limit frame 7. The limit frame 7 can limit the right end of the woven bag. A hydraulic cylinder 22 is fixedly installed at the top of the frame 1. The output end of the hydraulic cylinder 22 extends into the frame 1 and is fixedly installed on the lifting seat 2. The lifting seat 2 is raised and lowered by the hydraulic cylinder 22, which is beneficial to the use of this equipment. Multiple sliders 3 are fixedly installed at the front and rear ends of the lifting seat 2. Slide grooves 4 are provided at the front and rear ends of the frame 1 corresponding to the multiple sliders 3. The sliders 3 are slidably connected in the slide grooves 4.

The PLC controller 10 is used to control the operation of this equipment.

[0023] Working principle: The PLC controller 10 is electrically connected to the hydraulic cylinder 22, electric push rods 9, and motor 17 via connecting wires. During use, the extension switches of the two electric push rods 9 are turned on, causing the output ends of the two electric push rods 9 to slide the limit frame 7 to the right. Based on the position of the front end of the limit frame 7 on the distance scale 8, the distance between the limit frame 7 and the cutting groove 21 can be determined. After adjusting the limit frame 7 to the appropriate position, the woven bag to be cut is laid flat at the bottom of the machine frame 1, with the right end of the woven bag abutting against the limit frame 7. Then, based on the width of the woven bag, the switch of motor 17 is turned on. Motor 17 drives the threaded rod 15 to rotate, causing the moving beam 14 to slide the two moving seats 5 to the right, thus adjusting the distance between the first positioning plate 11 and the second positioning plate 12. Finally, the cutting switch is turned on. At this time, the output end of the hydraulic cylinder 22 drives the lifting seat 2 to descend. The first positioning plate 11 and the second positioning plate 12 will first press against both sides of the woven bag, and then, through the spring 18... The elastic force of the machine presses and fixes the woven bag. As the lifting seat 2 continues to descend, the woven bag can be cut by the hot cutting blade 13. The circuit connection method, mechanical structure and connection relationship not mentioned in this specification are all conventional technical means in this field, so they will not be described in detail. This kind of polymer woven bag production positioning and cutting machine is easy to use. The distance between the first positioning plate 11 and the second positioning plate 12 can be adjusted according to the needs of use, which is convenient to adapt to the needs of cutting and positioning woven bags of different widths, thereby further improving the applicability of this equipment. At the same time, the right end of the woven bag can be limited by the limiting frame 7 during the cutting process to ensure that the length of the woven bag cut each time is consistent, thereby improving the cutting quality of the woven bag. It can also automatically press or release the pressing and limiting of the woven bag during the lifting seat 2, reducing the operation steps of the operator during the cutting process, thereby further improving the processing efficiency.
