Description

Technical Field

[0001] The utility model relates to the technical field of thin film bag production, in particular to a thin film bag production device. Background Art

[0002] A thin film bag is usually a bag-shaped package made of soft and thin materials, which is usually used for packaging various items, such as food, medicine, cosmetics, industrial products, etc. It is also an essential item in people's daily life. A thin film bag production device is needed in the production and processing of thin film bags.

[0003] After retrieval, the Chinese patent publication number is: CN215037763U, which discloses a bag cutting device for the production and processing of plastic thin film bags, including a bearing plate; support columns, and two support columns are provided. Both support columns are fixedly connected to the bearing plate. In the utility model, the rotation of the driving motor drives the first rotating rod and the rotating wheel to rotate. Since the first rotating rod is located at the eccentric position of the rotating wheel, the rotation of the first rotating rod causes the rotating wheel to perform an eccentric motion. The eccentric motion of the rotating wheel pushes the T-shaped plate to move downward through the mutual cooperation of the limiting groove and the T-shaped plate. When the T-shaped plate moves downward, the spring is compressed. The movement of the T-shaped plate also drives the connecting rod and the cutting knife to move downward, and the plastic bag is cut by the cutting knife. Through the mutual cooperation of the rotating wheel, the limiting groove, the T-shaped plate and the connecting rod, the T-shaped plate makes a reciprocating motion. The reciprocating motion of the connecting rod drives the cutting knife to reciprocate. The continuous cutting of the plastic bag by the cutting knife greatly improves the practicability. However, in the actual use process of this device, it only cuts the thin film through the cutting structure, and when forming the thin film into a thin film bag, it is necessary to iron the cutting part synchronously. The asynchronous cutting and ironing may cause the cutting part and the ironing part to be mismatched, resulting in poor forming effect of the thin film bag, thus reducing the practicability of the device.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Refer to Figure 1 、 Figure 3 And Figure 4 As shown in, an embodiment provided by the present invention: a film bag production device includes a bracket 1. A reserved groove 3 is provided on the front side of the bracket 1. A T-shaped block 4 is slidably connected to the inner side of the reserved groove 3. A fixed plate 5 is fixedly connected to the middle of the front side of the bracket 1. Electric telescopic rods 6 are fixedly connected to the left and right sides of the top of the fixed plate 5. The telescopic ends of the two electric telescopic rods 6 are respectively fixedly connected to the left and right sides of the bottom of the T-shaped block 4. Rotating rollers 7 are rotatably connected to the left and right sides of the inner wall of the bracket 1. A placing roller 20 is rotatably connected to the left side of the inner wall of the bracket 1. A film 19 is arranged on the outer side of the placing roller 20. The placing roller 20 is in transmission connection with the rotating roller 7 through the film 19. A lifting plate 8 is fixedly connected to the left side of the rear end of the T-shaped block 4. An iron 9 is fixedly connected to the top of the lifting plate 8. A positioning plate 10 is fixedly connected to the right side of the top of the T-shaped block 4. A cutting edge 11 is fixedly connected to the inner wall of the bracket 1 corresponding to the lower part of the positioning plate 10. A tightening mechanism 2 is arranged at the bottom of the inner side of the bracket 1; An outlet plate 12 is fixedly connected to the right side of the bracket 1. Chutes 13 are provided on the front and rear sides of the top of the outlet plate 12. A moving plate 14 is arranged on the top of the outlet plate 12. The outlet plate 12 is slidably connected to the moving plate 14 through the chutes 13;

[0031] Specifically, starting the servo motor 18 can drive the placement roller 20 to rotate. The rotation of the placement roller 20 can transmit power through the film 19 wrapped thereon, thereby driving the rotating roller 7 to rotate. Starting the electric telescopic rod 6 can drive the T-block 4 to move up and down along the reserved groove 3. Moving the T-block 4 can drive the lifting plate 8 and the positioning plate 10 to move up and down. At the same time, starting the ironer 9 can heat the film 19 when the lifting plate 8 contacts the film 19, so that the double-layer film 19 is ironed to form a bag-shaped structure. At the same time, as the positioning plate 10 moves up and down, the ironed part of the film 19 will contact the cutting blade 11 to cut the film 19. The film 19 will move to abut against the left side of the moving plate 14. By moving the moving plate 14 along the slide groove 13, we can adjust the length of the single cut film 19 by shortening or reducing the distance between the film 19 and the moving plate 14.

[0037] Specifically, the starting controller 21 can respectively control the starting and operating power between the electric telescopic rod 6, the ironing machine 9, the blower 17, the servo motor 18 and the electric bidirectional telescopic rod 202. The outer shell 22 can enhance the protection effect of the controller 21. By opening and closing the protective cover 23, the controller 21 can be prevented from being accidentally touched when the controller 21 is not in use.

[0038] Working principle: Before using the device, first start the servo motor 18 to drive the placement roller 20 to rotate. The rotating placement roller 20 can drive the rotating roller 7 to rotate through the film 19 wrapped thereon. At this time, start the electric telescopic rod 6 to drive the T-block 4 to move up and down along the reserved groove 3. The moving T-block 4 can drive the lifting plate 8 and the positioning plate 10 thereon to move up and down. At this time, start the ironing device 9 to iron the double-layer film 19 when the lifting plate 8 contacts the film 19 to form a bag-shaped structure.
