Description

Technical Field

[0001] This utility model relates to the field of trimming mechanism technology, specifically to a trimming mechanism for a plastic film casting machine. Background Technology

[0002] Cast film machine refers to specialized equipment for producing cast film. First, the pulverized powder is mixed with binder, plasticizer, dispersant and solvent to form a slurry with a certain viscosity. The slurry flows down from the hopper and is scraped and pressed onto a special base belt with a certain thickness by a doctor blade. After drying and curing, it is peeled off from the top to become a green film. After the film is produced, there may be uneven edges, so it is necessary to trim the edges of the film.

[0003] For example, the published patent document CN216968022U discloses a trimming mechanism for a casting machine used in plastic film preparation. This mechanism involves installing a support plate on a base, rotating a threaded rod on the support plate, and threading a movable seat onto the threaded rod. A cutting blade is fixedly installed on the movable seat, and the position of the cutting blade is adjusted by moving the movable seat on the threaded rod, thereby cutting the film on the base. However, the cutting direction of the cutting blade in this mechanism is fixed, and it is difficult to change the direction of the cutting blade. Therefore, the cutting direction of the cutting blade on the film has certain limitations, making it difficult to effectively cut and trim the four sides of the film. Utility Model Content

The adjusting ring 5 is fixedly installed between the two connecting rods 4. The rotating component is set on the adjusting ring 5 and is used to rotate the cutting blade 1. The conveying component is set on the base plate 2 and is used to convey the plastic film. First, the plastic film moves to the cutting groove when passing through the conveying component and the film pressing component. Then, the cutting component and the cutting blade 1 cut the edges of the plastic film. After cutting, the angle of the cutting blade 1 can be adjusted by the rotating component and the adjusting ring 5 to cut the other edges of the plastic film.

[0029] In this embodiment, reference Figure 2The moving assembly includes a threaded rod 101, a motor 102, a moving block 103, a slide rod 104, and a connecting block 105. The threaded rod 101 is rotatably mounted on the support frame 3. The motor 102 is mounted on the support frame 3, and its output end is fixedly connected to the threaded rod 101.

The connecting block 105 is slidably mounted on the slide rod 104 and is fixedly mounted on the top of the moving block 103. When the motor 102 is started, it drives the threaded rod 101 to rotate on the support frame 3. The moving block 103 then moves left and right on the threaded rod 101. The slide rod 104 and the connecting block 105 ensure that the moving block 103 does not rotate when the threaded rod 101 rotates. The moving block 103 then drives the cutting blade 1 to adjust its position.

[0030] In this embodiment, reference Figure 2 The rotating assembly includes a rotating shaft 201, a rotating frame 202, a fixed rod 203, and bolts 204. The rotating shaft 201 is rotatably mounted on the bottom end of the moving block 103.

The cylinder 303 is installed on the side of the base plate 2, and the output end of the cylinder 303 is fixedly connected to the side of the conveying frame 301. When the plastic film is placed on the conveying roller, the film can be moved forward on the base plate 2 by rotating the conveying roller 302, so that it moves to the cutting groove for cutting. The cylinder 303 can be activated to adjust the position of the conveying roller 302 and the plastic film, thereby adjusting the position of the cutting edge.

[0032] In this embodiment, reference Figure 4It also includes a cutting assembly, which includes a placement frame 401, a motor 402, and a cutting shaft 403.

The cutting shaft 403 is fixedly connected to the output end of the motor 402 and is also fixedly connected to the cutting blade 1. When the motor 402 is started, it drives the cutting shaft 403 to rotate, which in turn drives the cutting blade 1 to rotate. The cutting blade 1 is located inside the cutting groove, thereby cutting the plastic film that has moved to the cutting groove position.

[0033] In this embodiment, reference Figure 5 It also includes a film pressing assembly, of which there are two. The film pressing assembly includes a sliding frame 1 501, a sliding plate 502, a sliding frame 2 503, a slide rail 504, and a pushing assembly. The sliding frame 1 501 is slidably installed in the slide groove on the side of the conveyor frame 301. The sliding plate 502 is slidably installed in the slide groove on the base plate 2. The sliding frame 2 503 is slidably installed on the side of the sliding plate 502. The slide rail 504 is fixedly installed between the sliding frame 1 501 and the sliding frame 2 503.

[0034] In this embodiment, reference Figure 5 The pushing assembly includes a second cylinder 505, a film pressing rod 506, and a pushing frame 507. The second cylinder 505 is mounted on the conveyor frame 301. The film pressing rod 506 is slidably mounted within the slide rail 504. The pushing frame 507 is fixedly mounted on the top of the film pressing rod 506, and its side is fixedly connected to the output end of the second cylinder 505. The slide rail 504 is lifted, and one end of the plastic film is placed on the base plate 2. Then, the sliding frame 501 and the sliding... The second frame 503 is moved to the bottom of the groove of the conveyor frame 301 and the groove of the sliding plate 502. When the first sliding frame 501 and the second sliding frame 503 slide to the bottom of the groove of the conveyor frame 301 and the groove of the sliding plate 502 respectively, the pressure rod 506 contacts the top of the bottom plate 2, thereby pressing the film with the pressure rod 506. The second cylinder 505 is activated, and the second cylinder 505 pushes the pressure rod 506 to move on the slide rail 504, thereby moving the plastic film forward.

[0035] In this embodiment, when trimming the plastic film, the produced plastic film is first wound around the conveyor roller 302. Then, one end of the plastic film is pulled out and placed on the base plate 2. The sliding frame 501 and the sliding frame 503 are slid in the chute, thereby lifting the slide rail 504 and placing the plastic film on the base plate 2. Then, the sliding frame 501 and the sliding frame 503 are slid to the bottom of the chute, so that the pressure rod 506 presses down on the plastic film. The cylinder 505 is activated, which drives the pusher 507 and the pressure rod 506 to move, thereby moving the plastic film to the cutting groove. The motor 402 is activated, which drives the cutting shaft 403 and the cutting blade 1 to rotate, thereby cutting. The conveyor 301 and the sliding frame 504 can also be pushed by the cylinder 503. The cutting edge is adjusted by positioning the frame in the chute. After cutting, the rotating shaft 201 can be rotated, and the rotating frame 202 is slidably installed in the circular chute, thereby driving the fixed rod 203 and the rotating frame 202 to rotate on the adjusting ring 5, thus adjusting the angle of the cutting blade 1 to rotate 90 degrees. Then, the bolt 204 is threaded into the corresponding threaded hole of the adjusting ring 5 and the threaded hole of the rotating frame 202 to fix it, thereby cutting the other edge of the plastic film again. The motor 102 can be started, which drives the threaded rod 101 to rotate on the support frame 3, and the moving block 103 moves left and right on the threaded rod 101, thereby driving the cutting assembly and the cutting blade 1 to move left and right, and the cutting edge can be adjusted again.
