Description

Technical Field

[0001] The utility model relates to the technical field of explosion-proof film winding, in particular to a winding device for processing explosion-proof films. Background Technique

[0002] An explosion-proof film is a metal film installed on the upper part of a pressure vessel to prevent the vessel from exploding. It is a safety device, also known as an explosion-proof sheet or bursting disc. When the pressure in the container exceeds a certain limit, the film is first broken, thus reducing the pressure in the container and avoiding explosion. It is widely used in pressure vessels. The term "explosion-proof film" sometimes specifically refers to the front windshield film. During the processing of explosion-proof films, a winding device is generally required to wind them for subsequent storage.

[0003] According to an explosion-proof film winding device with the publication number of CN220811240U, which includes a base. On both sides of the upper end surface of the base, a first fixed column and a second fixed column are respectively fixedly connected. The upper ends of the first fixed column and the second fixed column are fixedly connected with a top plate. A rotating shaft is rotatably arranged between the first fixed column and the second fixed column. A winding roller is fixedly sleeved on the outer wall of the rotating shaft. On one side of the upper end surface of the base close to the second fixed column, a first driving motor is fixedly arranged. The output end of the first driving motor is fixedly connected with a driving pulley. In the utility model, through the functions of automatic winding and convenient adjustment of the limit, a stable limiting effect during winding can be achieved, so that a better winding effect can be achieved. At the same time, the adjustable fixing and clamping effect on the thickness of one side of the wound explosion-proof film can further achieve a better problem of preventing detachment, and has better practicability and protection.

[0004] In view of the above related solutions, the above limits the two sides of the explosion-proof film during the winding process through a limit rod with adjustable width. However, the size of the winding roller is fixed, so that when winding an explosion-proof film with a larger width, the parts of the two sides of the explosion-proof film exceeding the winding roller are prone to uneven stress or even deviation due to the lack of effective support and restraint of the winding roller, which is likely to affect the winding of the explosion-proof film.

By starting the driving motor 9, the output end of the driving motor 9 drives the support shaft 3 and the winding roller 4 to rotate under the action of the pulley group 8, so that the winding operation of the explosion-proof membrane can be facilitated through the winding roller 4.

[0025] Referring to Figure 1 、 Figure 2 and Figure 3 it can be known that a limiting groove 13 is opened inside the first movable frame 401, a limiting block 12 is welded and connected inside the second movable frame 402, and the first movable frame 401 and the second movable frame 402 form a sliding structure through the limiting block 12 and the limiting groove 13. The limiting block 12 and the limiting groove 13 play a role in supporting and limiting the first movable frame 401 and the second movable frame 402, so that the first movable frame 401 and the second movable frame 402 slide horizontally. One end of the support shaft 3 away from the support block 501 is welded and connected with a guide rod 7 passing through the first movable frame 401 and the second movable frame 402.

[0030] Referring to Figure 4 As can be seen, guide blocks 11 are symmetrically welded and connected to the inner sides of the first movable frame 401 and the second movable frame 402. Guide grooves 10 are symmetrically formed on the surface of the support shaft 3. The first movable frame 401, the second movable frame 402 and the support shaft 3 form a sliding structure through the guide grooves 10 and the guide blocks 11, which can play a role in supporting and limiting, so that the first movable frame 401 and the second movable frame 402 can rotate together with the support shaft 3.
