Description

Technical Field

[0001] This utility model relates to the field of film processing technology, and in particular to an integrated device for cutting and winding antibacterial PVC film. Background Technology

[0002] Antibacterial PVC film is a functional film made by adding antibacterial agents to PVC film. It not only retains the original flexibility, transparency, and durability of PVC film but also possesses excellent antibacterial properties. This film can effectively inhibit the growth and reproduction of bacteria, mold, and other microorganisms, preventing product spoilage or harm to human health caused by microbial infection. Therefore, antibacterial PVC film is widely used in medical, food packaging, and household goods fields, providing a safer and more hygienic guarantee for people's lives.

[0003] In the existing production process of antibacterial PVC film, the film is usually cut by a cutting machine and then wound onto a winding roller by a winding mechanism for later use. The device structure is relatively complex, the device is large, and it is time-consuming and labor-intensive, causing inconvenience to operators and affecting work efficiency. To address this, we have designed an integrated device for cutting and winding antibacterial PVC film. Utility Model Content

[0004] The purpose of this invention is to provide an integrated device for cutting and winding antibacterial PVC film to solve the problems mentioned in the background art.

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

[0006] An integrated device for cutting and winding antibacterial PVC film includes a workbench. The top of the workbench is equipped with a mounting frame and two fixing rods. Two sliding rods are slidably inserted into the top of the mounting frame. The bottom ends of the two sliding rods are connected to an arc-shaped pressure plate. A first spring is sleeved on the outside of the sliding rods. A winding roller and a guide roller are rotatably mounted on the inner side wall of the mounting frame. A drive motor is mounted on the rear outer wall of the mounting frame. A lifting cross plate is slidably sleeved on the outer side of the two fixing rods. A mounting plate is located at the bottom of the lifting cross plate, and a cutting blade is detachably mounted on the bottom of the mounting plate. The mounting bracket has a horizontally oriented groove on its inner top wall. A threaded rod is rotatably mounted between the inner walls of the left and right sides of the groove. A movable block is threaded onto the outer side of the threaded rod. The movable block is slidably mounted in the groove. A U-shaped frame is provided at the bottom of the movable block. A linkage rod is rotatably mounted on the inner side of the U-shaped frame through a connecting mechanism. Inner rods are inserted into the left and right ends of the linkage rod. One end of the inner rod away from the linkage rod is movably connected to the arc-shaped pressure plate through a first hinge seat. The other end of the inner rod away from the linkage rod is movably connected to the lifting cross plate through a second hinge seat.

[0007] As a preferred embodiment of this utility model: the connecting mechanism includes guide rods symmetrically arranged on the front and rear sides of the linkage rod, the guide rods are fixedly arranged between two support plates, the support plates are fixedly arranged on the outer surface of the linkage rod, and sliders are slidably sleeved on the outer sides of the two guide rods. Rotating shafts are symmetrically arranged on the sides of the two sliders that are far apart from each other. A limiting circular plate is provided at the other end of the rotating shaft. A circular hole for the rotating shaft to be inserted is provided through the lower part of the inner side wall of the U-shaped frame.

[0008] As a further preferred embodiment of this utility model: the left and right ends of the linkage rod are respectively provided with slots for the inner rod to slide into, and the inner bottom wall of the slot is provided with a second spring, the other end of the second spring being connected to the inner rod.

[0009] As a further preferred embodiment of this utility model: the guide roller is located to the lower right of the take-up roller, and the arc-shaped pressure plate is located directly above the take-up roller.

[0010] As a further preferred embodiment of this utility model: the first hinge seat is installed on the top of the arc-shaped pressure plate, the first hinge seat is located between the two slide rods, and the second hinge seat is installed on the top of the lifting horizontal plate.

[0011] As a further preferred embodiment of this utility model: the right end of the threaded rod extends through to the outside of the slide groove and is connected to a rotating handle, which is rotatably mounted on the right side surface of the mounting bracket.

[0012] As a further preferred embodiment of this utility model: the top end of the sliding rod is provided with a limiting block A, and the top end of the fixing rod is provided with a limiting block B.

[0013] As a further preferred embodiment of this utility model: one end of the first spring is connected to the bottom of the limiting block A, and the other end is connected to the top of the mounting bracket.

[0014] The beneficial effects of this utility model are as follows: As the thickness of the antibacterial PVC film on the winding roller increases, the arc-shaped pressure plate will be pushed upward. Under the combined action of the first hinge seat, the second hinge seat, and the connecting mechanism, the linkage rod will be driven to rotate, causing the left end of the linkage rod to move upward and the right end to move downward. This, in turn, drives the lifting horizontal plate, the mounting plate, and the cutting blade to move downward along the length of the fixed rod. As the thickness of the wound film increases, the cutting blade will eventually cut the film, completing one winding operation. The cutting is carried out automatically and synchronously. The device has a compact structure, concentrated functions, saves time and effort, brings convenience to workers, and improves work efficiency. In addition, this device can rotate the threaded rod by turning the handle, which in turn moves the moving block along with the U-shaped frame. This changes the position of the U-shaped frame on the linkage rod, which in turn changes the position of the linkage rod's rotation point. Consequently, it changes the length of the lever arms on the left and right sides of the rotation point, thus adjusting the film thickness that the take-up roller can hold. When the rotation point is more to the left of the midpoint of the linkage rod's length, the thickness of the film that can be wound onto the take-up roller is smaller, meaning less film is wound up. Conversely, when the rotation point is more to the right of the midpoint of the linkage rod's length, the thickness of the film that can be wound onto the take-up roller is larger, meaning more film is wound up. This improves the device's flexibility and practicality, and it is simple to operate and convenient to use. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] Please see Figure 1-5 In this embodiment of the present invention, an integrated device for cutting and winding antibacterial PVC film includes a workbench 1. The top of the workbench 1 is provided with a mounting frame 6 and two fixing rods 11. Two sliding rods 17 are slidably inserted into the top of the mounting frame 6. The bottom ends of the two sliding rods 17 are connected to an arc-shaped pressure plate 8. A limiting block A is provided at the top of the sliding rods 17. A first spring 15 is sleeved on the outside of the sliding rods 17. One end of the first spring 15 is connected to the bottom of the limiting block A, and the other end is connected to the top of the mounting frame 6. A winding roller 9 and a guide roller 10 are rotatably mounted on the inner side wall of the mounting frame 6. A drive motor for driving the winding roller 9 to rotate is provided on the rear outer wall of the mounting frame 6. A lifting cross plate 4 is slidably sleeved on the outer side of the two fixing rods 11. A mounting plate is provided at the bottom of the lifting cross plate 4. 3. A cutting blade 2 is detachably installed at the bottom of the mounting plate 3. A limiting block B is provided at the top of the fixing rod 11. A sliding groove 18 is opened in the horizontal direction on the inner top wall of the mounting frame 6. A threaded rod 19 is rotatably provided between the inner walls of the left and right sides of the sliding groove 18. A moving block 21 is threaded on the outside of the threaded rod 19. The moving block 21 is slidably set in the sliding groove 18. A U-shaped frame 20 is provided at the bottom of the moving block 21. A linkage rod 14 is rotatably provided on the inner side of the U-shaped frame 20 through a connecting mechanism. An inner rod 26 is inserted into the left and right ends of the linkage rod 14 respectively. One end of the inner rod 26 away from the linkage rod 14 is movably connected to the arc-shaped pressure plate 8 through the first hinge seat 7. The other end of the inner rod 26 away from the linkage rod 14 is movably connected to the lifting horizontal plate 4 through the second hinge seat 12.

[0024] The connecting mechanism includes guide rods 25 symmetrically arranged on the front and rear sides of the linkage rod 14. The guide rods 25 are fixedly arranged between two support plates 24, which are fixedly arranged on the outer surface of the linkage rod 14. Sliding blocks 23 are slidably sleeved on the outer sides of the two guide rods 25. Rotating shafts 13 are symmetrically arranged on the sides of the two sliding blocks 23 that are far apart from each other. The other end of the rotating shaft 13 is provided with a limiting circular plate 22. A circular hole is opened through the lower part of the inner side wall of the U-shaped frame 20 for the rotating shaft 13 to be inserted. The connecting mechanism has two functions: First, it allows the linkage rod 14 to rotate within the U-shaped frame 20. Second, the U-shaped frame 20 can move along the length of the linkage rod 14, that is, change the position of the U-shaped frame 20 on the linkage rod 14, that is, change the position of the rotation point of the linkage rod 14, and thus change the length of the lever arm on the left and right sides of the rotation point. This allows adjustment of the film thickness of the take-up roller 9 and automatic cutting. See the working principle below for details.

[0025] The left and right ends of the linkage rod 14 are respectively provided with slots 16 for the inner rod 26 to slide into. The inner bottom wall of the slot 16 is provided with a second spring 27, and the other end of the second spring 27 is connected to the inner rod 26. When the rotation point of the linkage rod 14 changes, when the linkage rod 14 rotates, under the cooperation of the first hinge seat 7 and the second hinge seat 12, the inner rod 26 will move and slide in the slot 16 to ensure the normal movement of the arc-shaped pressure plate 8 and the normal movement of the lifting horizontal plate 4, and to ensure the feasibility and practicality of the cooperation between the various components of the device.

[0026] The guide roller 10 is located to the lower right of the take-up roller 9, and the arc-shaped pressure plate 8 is located directly above the take-up roller 9.

[0027] The first hinge seat 7 is installed on the top of the arc-shaped pressure plate 8, and the first hinge seat 7 is located between the two slide rods 17. The second hinge seat 12 is installed on the top of the lifting horizontal plate 4.

[0028] The right end of the threaded rod 19 extends through the outside of the slide groove 18 and is connected to a handle 5, which is rotatably mounted on the right side surface of the mounting bracket 6.

[0029] Working Principle: In this device, as the thickness of the antibacterial PVC film on the winding roller 9 increases, it pushes the arc-shaped pressure plate 8 upward. Under the combined action of the first hinge seat 7, the second hinge seat 12, and the connecting mechanism, the linkage rod 14 rotates, causing the left end of the linkage rod 14 to move upward and the right end to move downward. This, in turn, drives the lifting horizontal plate 4, the mounting plate 3, and the cutting blade 2 to move downward along the length of the fixed rod 11. As the thickness of the wound film increases, the cutting blade 2 eventually cuts the film, completing one winding operation. The cutting is performed automatically and synchronously. The device has a compact structure, concentrated functions, saves time and labor, brings convenience to workers, and improves work efficiency. In addition, this device... Rotating the handle 5 drives the threaded rod 19 to rotate, which in turn moves the moving block 21 along with the U-shaped frame 20, thus changing the position of the U-shaped frame 20 on the linkage rod 14, which in turn changes the position of the rotation point of the linkage rod 14. This changes the length of the lever arms on the left and right sides of the rotation point, thereby adjusting the film thickness that the take-up roller 9 can hold. When the rotation point is more inclined to the left of the midpoint of the linkage rod 14 along its length, the thickness of the film that can be taken up on the take-up roller 9 is smaller, meaning less film is taken up. When the rotation point is more inclined to the right of the midpoint of the linkage rod 14 along its length, the thickness of the film that can be taken up on the take-up roller 9 is larger, meaning more film is taken up. This improves the flexibility and practicality of the device, and it is simple to operate and convenient to use.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
