Description

Technical Field

[0001] This utility model relates to the field of cast film production technology, and in particular to a casting film winding and trimming device. Background Technology

[0002] Cast film is a type of non-stretched, non-oriented flat extrusion film produced by rapidly cooling melt casting. There are two methods: single-layer casting and multi-layer co-extrusion casting.

[0003] After the cast film raw material is extruded, an operator guides the end of the material through a traction machine. After being stretched, it is recycled. Because cast film is highly deformable and soft, the edges of the cast film are irregular during stretching. Therefore, the traction machine is equipped with blades to trim the edges of the cast film. The operator manually adjusts the distance between the blades according to the size and width of the cast film. Cast films come in various sizes, and each time a different size of cast film is drawn, the blade spacing needs to be adjusted, and manual adjustment of the distance is too inaccurate. Utility Model Content

[0004] The purpose of this application is to provide a winding and trimming device for cast film winding to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A casting film winding and trimming device includes a mounting rod and a trimming assembly mounted on the mounting rod. A fixing plate is mounted on the end of the mounting rod via a bearing. A second motor is fixedly mounted on the side of the fixing plate away from the mounting rod. The mounting rod is driven by the second motor. The trimming assembly includes a first cylinder, a second cylinder, a fixed housing, and a blade. The first and second cylinders are fixedly mounted on the upper outer wall of the mounting rod. The first cylinder is mounted close to the fixing plate. Two fixed housings are provided. A movable ring is fixedly mounted on the output end of both the first and second cylinders. The movable ring is sleeved on the outer wall of the first mounting rod, and the fixed housing is fixedly mounted on the outer wall of the movable ring. The blade is movably mounted inside the fixed housing.

[0007] Preferably, a motor is fixedly mounted on one outer wall of the mounting rod, and a screw is provided on the other side of the mounting rod. The output end of the motor passes through the mounting rod and is fixedly connected to the screw. A moving block is threaded onto the outer wall of the screw, and both blades are pulsatorically connected to the moving block. A guide rod is fixedly mounted on the outer wall of the moving block facing the mounting rod. The guide rod passes through the outer wall of the mounting rod, and its installation direction is parallel to the screw.

[0008] Preferably, both outer walls of the two fixed shells are provided with through grooves. A fastening head is movably installed on one outer wall of the fixed shell, and the fastening head is embedded in the corresponding groove. A connecting head is movably installed on the other outer wall of the fixed shell, and the connecting head is embedded in the corresponding groove. A bolt is fixedly installed at one end of the fastening head, and a threaded hole is opened on the outer wall of one end of the connecting head. The bolt of the fastening head passes through the outer wall of the end of the blade and is threadedly connected to the threaded hole of the connecting head.

[0016] like Figure 1-4 The illustrated casting film winding and trimming device includes a mounting rod 1 and a trimming assembly mounted on the mounting rod 1. A fixing plate 16 is mounted on the end of the mounting rod 1 via a bearing. A motor 15 is fixedly mounted on the side of the fixing plate 16 away from the mounting rod 1. The mounting rod 1 is driven by the motor 15. The trimming assembly includes a cylinder 2, a cylinder 3, a fixing shell 4, and a blade 6. Cylinders 2 and 3 are fixedly mounted on the upper outer wall of the mounting rod 1. Cylinder 2 is mounted close to the fixing plate 16. There are two fixing shells 4. A moving ring 10 is fixedly mounted on the output end of both cylinders 2 and 3. The moving ring 10 is sleeved on the outer wall of the mounting rod 1. The fixing shell 4 is fixedly mounted on the outer wall of the moving ring 10. The blade 6 is movably mounted inside the fixing shell 4.

[0017] A motor 11 is fixedly mounted on one side of the outer wall of the mounting rod 1, and a screw 14 is provided on the other side of the mounting rod 1. The output end of the motor 11 passes through the mounting rod 1 and is fixedly connected to the screw 14. A moving block 13 is threadedly mounted on the outer wall of the screw 14, and both blades 6 are drivenly connected to the moving block 13. A guide rod 12 is fixedly mounted on the outer wall of the moving block 13 facing the mounting rod 1. The guide rod 12 passes through the outer wall of the mounting rod 1, and the installation direction of the guide rod 12 is parallel to that of the screw 14.

[0018] Both outer walls of the two fixed shells 4 are provided with through grooves 7. A fastening head 17 is movably installed on one outer wall of the fixed shell 4 and is embedded in the corresponding groove 7. A connecting head 5 is movably installed on the other outer wall of the fixed shell 4 and is embedded in the corresponding groove 7. A bolt is fixedly installed at one end of the fastening head 17 and a threaded hole is opened on the outer wall of one end of the connecting head 5. The bolt of the fastening head 17 passes through the outer wall of the end of the blade 6 and is threadedly connected to the threaded hole of the connecting head 5. The outer wall of the movable block 13 is provided with two through slots. A sliding rod 8 is installed through one slot and a sliding rod 9 is installed through the other slot. The end of the sliding rod 8 is fixedly connected to one of the connecting heads 5 and the end of the sliding rod 9 is fixedly connected to the other connecting head 5.

[0019] Example: Mounting rod 1 is fixed to the cast film winding machine by fixing plate 16. Mounting rod 1 is installed above the cast film traction shaft. Motor 2 15 drives mounting rod 1 to rotate. Cylinder 1 2 and Cylinder 2 3 drive moving ring 10 to slide on mounting rod 1, which can adjust the distance between the two fixing shells 4. The distance between fixing shells 4 represents the distance between blades 6, thus allowing the distance between blades 6 to be changed, enabling trimming of cast films of different widths. Motor 1 11 starts, driving screw 14 to rotate. Screw 14 drives moving block 13 away from mounting rod 1. When moving block 13 moves, guide rod 12 slides inside mounting rod 1, fixing the direction of movement of moving block 13. Moving block 13 drives slide rod 1 8 and slide rod 2 9 to move. Slide rod 1 8 and slide rod 2 9 drive corresponding connectors 5. Connector 5 drives blades 6 to extend out of fixing shells 4. Connector 5 and fastening head 17 slide inside slide groove 7. Motor 215 drives the mounting rod 1 to rotate, causing the blade 6 to cut into the cast film below and cut the edge of the cast film.

[0020] Both slide rod 8 and slide rod 9 can slide within the slot of the moving block 13, allowing the two fixed shells 4 to change position while the two blades 6 extend simultaneously without interference. The fastening head 17 and the connecting head 5 hold the blades 6 in the middle. The fastening head 17 is threadedly connected to the connecting head 5 by bolts. When the blades 6 need to be replaced, the fastening head 17 is rotated to remove it from the slide groove 7, and the blades 6 can also be removed from the fixed shells 4 for replacement.
