The cutting structure 2 includes first mounting plates 201 installed on both sides of the winding structure 1. The connection between the cutting structure 2 and the winding structure 1 is achieved by installing two first mounting plates 201.

The rotating connecting rod 203 is rotatably connected to the two first mounting plates 201, and the fixed connecting rod 205 is connected to the first mounting plate 201. The connection is fixed. Rotary connecting plates 207 are installed on both sides of the fixed connecting rod 205. The two rotating connecting plates 207 are fixedly connected to the fixed connecting rod 205. The ends of the two rotating connecting plates 207 are rotatably connected to two first propulsion cylinders 206. The opposite sides of the two first propulsion cylinders 206 are provided with second mounting plates 202 that are fixedly connected to the winding structure 1 of the device. Several locking structures 208 are provided on the rotating connecting rod 203 and the fixed connecting rod 205. A cutting blade assembly 204 is installed on one side of each of the locking structures 208.

[0024] The locking structure 208 includes a locking housing 2081. A mounting ring 2001 is located at the bottom of the locking housing 2081. A snap-fit ​​plate 200 is located on one side of the locking housing 2081, connecting the locking housing 2081 and the mounting ring 2001. The upper part of the snap-fit ​​plate 200 is fixedly connected to the locking housing 2081, while the lower part of the snap-fit ​​plate 200 is rotatably snapped into contact with the mounting ring 2001. The interior of the locking housing 2081 contains four first pressure chambers 2082. Each of the four first pressure chambers 2082 has a sliding push-out rod 2083 that penetrates through it. One end of each of the four push-out rods 2083 is provided with a locking plate 2084. The locking plate 2084 is composed of two materials: the material that fits against the rotating connecting rod 203 is a rubber material that increases friction, and the material that connects to the push-out rod 2083 is a steel plate. One side of each of the four push-out rods 2083 is provided with... There is a tension spring 2085 inside the locking housing 2081. The two ends of the tension spring 2085 are fixedly connected to one side of the push rod 2083 and the side of the first pressure chamber 2082 near the connection of the access oil pipe 2086, respectively. One end of each of the four locking housings 2081 is provided with an access oil pipe 2086. The total end of the access oil pipe 2086 is connected to the second pressure chamber 2087. The second pressure chamber 2087 is provided with a pressure plate 2088. The second pressure chamber 2087 is also provided with a rotating threaded rod 2089 that passes through the second pressure chamber 2087 and is threadedly connected to the pressure plate 2088. The connection between the rotating threaded rod 2089 and the second pressure chamber 2087 is a rotatable connection. The cutting blade assembly 204 includes a cutting mounting plate 2041. A second propulsion cylinder 2042 is fixedly connected inside the cutting mounting plate 2041. A push blade 2043 is installed on the push shaft of the second propulsion cylinder 2042.

[0025] The rotating connecting rod 203 is installed at a slightly lower center position between the two first mounting plates 201. The fixed connecting rod 205 is installed at a slightly rearward position above the rotating connecting rod 203. The first propulsion cylinder 206 is installed at an angle between the second mounting plate 202 and the first propulsion cylinder 206. The mounting ring 2001 has a slot inside. The bottom of the rotating connecting rod 203 is provided with an installation strip. The first pressure chamber 2082 is sleeved on the rotating connecting rod 203. Two limiting blocks are installed in the first pressure chamber 2082. The first pressure chamber 2082, the passage oil pipe 2086, and the second pressure chamber 2087 are filled with hydraulic oil.

[0026] Working principle:

[0027] Before using the device, first check all its components to ensure that they work properly and that the device can operate normally.

[0028] When the user needs to cut plastic films of different widths during the use of the device, the user can rotate the rotating threaded rod 2089 to make it rotate. When the rotating threaded rod 2089 rotates, it promotes the movement of the pressure plate 2088 connected to it in the second pressure chamber 2087. When the pressure plate 2088 moves, the hydraulic oil in the second pressure chamber 2087 will increase or decrease in pressure. When the pressure plate 2088 moves to expand the space in the second pressure chamber 2087, the tension spring 2085 pulls the push rod 2083 and the locking plate 2084 to move. The hydraulic oil in the first pressure chamber 2082 enters the passage oil pipe 2086. The four locking plates 2084 are no longer locking the rotating connecting rod 203. When the user pushes the locking shell 2081, the locking shell 2081 drives the snap plate 200 and the mounting ring 2001 to move on the rotating connecting rod 203 and the fixed connecting rod 205. When it moves to the appropriate position, the user resets the device to achieve the locking device to the appropriate position.

[0029] By incorporating the cutting structure 2, users can freely adjust the cutting width, avoiding the problem of fixed and inflexible cutting widths found in existing devices. Furthermore, this design allows for the installation of multiple sets of cutting blades, enabling quick and convenient blade replacement when the device ceases operation due to blade wear.

[0030] Once the user determines the adjustable width, the user activates the second propulsion cylinder 2042, which pushes out the push-out blade 2043. When the push-out blade 2043 comes into contact with the film covering the winding structure 1 of the device, cutting is achieved.

[0031] When the film thickness on the device becomes thinner and the film is raised, the user activates the first propulsion cylinder 206. The first propulsion cylinder 206 drives the rotating connecting plate 207, the rotating connecting rod 203, and the cutting blade assembly 204 to rotate between the first mounting plate 201, thereby realizing the angle adjustment of the cutting blade assembly 204.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
