Description

Technical Field

[0001] This utility model relates to the technical field of composite film cutting equipment, specifically a positioning mechanism for a composite film cutting device. Background Technology

[0002] Composite membranes are thin films made of two or more different materials bonded together in a specific way. They are widely used in packaging, separation, and seepage prevention. Their structure and function vary depending on the application scenario. Common types include separation membranes, geomembranes, and packaging films. During the production and processing of composite membranes, they often need to be cut into different lengths according to usage requirements. Therefore, composite membrane cutting equipment is required, and the positioning mechanism is an indispensable component of composite membrane cutting equipment.

[0003] A search revealed patent application CN202220833444.3, which discloses a composite film cutting device for medical packaging bag production. It includes an operating table and an extrusion assembly mounted on top of the operating table. Threaded columns are provided on both sides of the top of the operating table. The extrusion assembly includes a pair of support columns connected by a U-shaped rod. An extrusion column is sleeved on the outer side of the U-shaped rod. A sleeve column is provided at the bottom end of each support column, with its inner side threadedly connected to the threaded column. In this invention, rotating the sleeve columns causes them to rotate threadedly with the threaded column, moving them up and down along the threaded column. This movement drives the support columns up and down, which in turn moves the U-shaped rod up and down. This allows for free adjustment of the gap between the extrusion column and the support table, accommodating the extrusion of composite films of different thicknesses. This ensures that the composite film of different thicknesses remains smooth during the cutting process, avoiding wrinkles that could lead to uneven cuts and affect subsequent use.

[0004] However, this patent has its shortcomings. The positioning component on this composite film cutting device can only press and fix one end of the composite film, and its functionality is relatively simple. In actual use, after each cut, the operator needs to manually pull the composite film to the right to extend it before the next cut can be made, which greatly increases the workload of the operator. Moreover, due to the lack of a measuring structure, the operator cannot judge the length of the composite film during the process of pulling it to the right, which leads to inaccurate length of the composite film cut later and affects the cutting quality.

[0005] Therefore, we propose a positioning mechanism for a composite film cutting device. Utility Model Content

[0023] Two hydraulic cylinders 19 are fixedly installed at the top of the frame 1. The output ends of the two hydraulic cylinders 19 extend into the frame 1 and are fixedly installed with cutting blades 18. The hydraulic cylinders 19 drive the cutting blades 18 to rise and fall, which facilitates the cutting of the composite film. A motor 12 is fixedly installed at the front end of the U-shaped frame 11. The output end of the motor 12 is fixedly installed on the transmission rod 13. The motor 12 drives the transmission rod 13 to rotate, which is beneficial to the use of this equipment. A motor 10 is fixedly installed on the right side of the cutting table 2. The output end of the motor 10 is fixedly installed on the threaded rod 9. The motor 10 drives the threaded rod 9 to rotate, which is beneficial to the use of this equipment. A PLC controller 5 is fixedly installed at the front end of the cutting table 2, located to the left of arrow 6. The PLC controller 5 is used to control the operation of this equipment. The front and rear ends of the first positioning frame 3 and the second positioning frame 4 are provided with limit grooves 21. The front and rear ends of the U-shaped frame 11 and the pressure plate 17 extend out of the limit grooves 21. The limit grooves 21 can limit the U-shaped frame 11 and the pressure plate 17. The pressure plate 17 is designed in a cross shape. This design is beneficial to the use of this equipment.

[0024] Working principle: The PLC controller 5, hydraulic cylinder 19, first cylinder 15, second cylinder 16, motor 12, and motor 10 are electrically connected via connecting wires. In use, the composite film to be cut is inserted into the first positioning frame 3. Then, the lowering switch of the first cylinder 15 is turned on, causing the output end of the first cylinder 15 to drive the U-shaped frame 11 to descend, pressing the roller 14 onto the composite film. Then, the switch of the motor 12 is turned on, causing the motor 12 to drive the transmission rod 13 and roller 14 to rotate, conveying the composite film to the right into the second positioning frame 4. Then, the pressing switch of the second cylinder 16 is turned on, causing the second cylinder 16 to drive the pressure plate 17 to descend and press onto the composite film for fixation. Then, the switch of the motor 10 is turned on, causing the motor 10 to drive the threaded rod 9 to rotate, causing the slide 8 to drive the second positioning frame 4 to slide to the right, thus pulling the composite film to the right. According to the position of arrow 6 on the distance scale 7, after pulling the composite film to the appropriate length, the cutting switch is turned on. At this time, the first cylinder 15 continues to drive... The U-shaped frame 11 descends to press the composite film, and then the output end of the hydraulic cylinder 19 drives the cutting blade 18 to descend, allowing the blade on the cutting blade 18 to cut the composite film. Then, the hydraulic cylinder 19 drives the cutting blade 18 to rise and reset, and the second cylinder 16 drives the pressure plate 17 to rise and reset. The operator quickly removes the cut composite film, and then the motor 10 reverses to drive the second positioning frame 4 to slide to the left and reset. By programming the PLC controller 5, the equipment can automatically repeat the above operation steps. Circuit connection methods, mechanical structures, and connection relationships not mentioned in this specification are all conventional technical means in this field, and therefore will not be described in detail. The positioning mechanism of this composite film cutting device is easy to use. Through the above components, the composite film can be automatically conveyed and pulled after each cut without manual operation, which greatly reduces the workload of the operator. At the same time, it can accurately position the pulling length of the composite film, thereby ensuring the cutting quality of the composite film.
