[0022] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0023] Example: Please refer to Figure 1-3 The first and second elastic clamping mechanisms 6 are installed on the shaft 5 and can be opened and closed.
[0024] In this embodiment, a connecting plate 2 is fixed to the support plate 1, and a fixing block 3 is fixed to the connecting plate 2. A self-lubricating bearing 9 is provided inside the fixing block 3. One end of the rotating shaft 5 passes through the bearing seat, and one end of the rotating shaft 5 is rotatably connected to the self-lubricating bearing 9, which is beneficial to preventing the rotating shaft 5 from tilting, which is beneficial to improving the life of the bearing in the bearing seat. Among them, the self-lubricating bearing 9 can be a spherical graphite bearing; and one end of the rotating shaft 5 is provided with a first boss 10 that is in contact with the support plate 1, and the first elastic clamping mechanism 7 includes a first spring 11 fixed to the first boss 10 and sleeved on the rotating shaft 5, and a first clamping plate 12 fixed to one end of the first spring 11 away from the first boss 10. A plurality of first clamping rods are provided on the first clamping plate 12, thereby realizing elastic clamping of the material film roll 4, and also realizing clamping of material film rolls 4 of different widths, thereby improving the practicality of the device.
[0025] In this embodiment, a blind hole 13 is provided inside the rotating shaft 5, and a plurality of notches 20 are provided on the rotating shaft 5. The notches 20 are connected to the blind hole 13. The second elastic clamping mechanism 6 includes a moving block 14 slidingly connected to the blind hole 13, and a second clamping rod 18 rotatably connected to the moving block 14. The second clamping rod 18 is connected to the moving block 14 through a clip spring. The moving block 14 is connected to the end of the rotating shaft 5 through a second spring 15. A limit table 22 for limiting the rotation of the second clamping rod 18 is provided on the moving block 14. When the material film roll 4 needs to be removed, it only needs to move the moving block 14. When the second clamping rod 18 reaches the position of the notch 20, it will rotate under the action of the edge of the notch 20, thereby retracting the second clamping rod 18 to the blind hole. Inside the hole 13, the material film roll 4 can be removed and installed at this time. After the installation is completed, the moving block 14 will be reset under the action of the second spring 15, and the second clamping rod 18 will be opened. Under the action of the limit table 22, it will be pressed against the end of the material film roll 4, thereby achieving installation and clamping of different width sizes; and a square driving rod 16 is provided on the moving block 14, and the square driving rod 16 is slidably connected to the end of the rotating shaft 5 to prevent the moving block 14 from rotating; and a second boss is provided at the end of the square driving rod 16, and a pull ring 17 is provided on the second boss. A V-shaped spring piece 19 is embedded in the interior of the square driving rod 16, and the warhead of the V-shaped spring piece 19 passes through the square driving rod 16, and a pull ring 17 is provided on the inner end surface of the rotating shaft 5. The bullet is pressed into the guide inclined plate 23 inside the square driving rod 16. However, when the material film roll 4 needs to be disassembled, it is only necessary to pull the pull ring 17 to realize the movement of the moving block 14. When the bullet pops out from the end of the rotating shaft 5, the pull ring 17 can be released. At this time, the second spring 15 is compressed, the second clamping rod 18 is closed and both are located inside the blind hole 13. At this time, the material film roll 4 can be removed, and then a new material film roll 4 is pushed into the rotating shaft 5 and the first spring 11 is compressed. Then the bullet of the V-shaped spring piece 19 is pressed into the inside of the square driving rod 16. The moving block 14 will be reset under the action of the second spring 15. At the same time, the second clamping rod 18 is opened and pressed against the limit table 22 under the action of the clip spring. Then the material film roll 4 is released and the material film roll is released. The roll 4 will be clamped under the action of the first spring 11 and the second spring 15, and the clamped material film roll 4 will be located in the middle of the rotating shaft 5, thereby realizing the installation of material film rolls 4 of different widths; and a notch 24 is provided on the moving block 14, one end of the second clamping rod 18 is located inside the notch 24, and the limit platform 22 is located on both sides of the notch 24. The end face of the limit platform 22 is tightly attached to the second clamping rod 18, and a rotating groove 21 is provided on both sides of the second clamping rod 18. One end of the clip spring is connected to the moving block 14, and the other end of the clip spring is overlapped on the inner wall of the rotating groove 21. Under the action of the clip spring, the second clamping rod 18 is tightly attached to the end face of the limit platform 22, thereby realizing the connection between the second clamping rod 18 and the moving block 14.
[0026] How it works
[0027] When the film roll 4 needs to be replaced, first pull the pull ring 17 to move the moving block 14. When the bullet pops out from the end of the rotating shaft 5, the pull ring 17 can be released. At this time, the second spring 15 is compressed, and the second clamping rod 18 is closed in the process of twisting the clamp spring, and the second clamping rod 18 is located inside the blind hole 13. At this time, the film roll 4 can be removed, and then a new film roll 4 is pushed into the rotating shaft 5 and the first spring 11 is compressed. Then the bullet of the V-shaped spring piece 19 is pressed into the square drive rod 16, and the film roll 4 is moved. The block 14 will be reset under the action of the second spring 15, and at the same time, the second clamping rod 18 will be opened and tightly attached to the limit platform 22 under the action of the clamping spring, and then the material film roll 4 will be released. The material film roll 4 will be clamped under the action of the first spring 11 and the second spring 15, and the clamped material film roll 4 will be located in the middle of the rotating shaft 5, thereby realizing the installation of the material film roll 4; therefore, during the practical use of the present invention, the staff does not need to disassemble and assemble the rotating shaft 5 to realize the replacement of the material film roll 4, and the operation is convenient.
[0028] It is only necessary to close the clamping end of the second elastic clamping mechanism to take out the used bottom roll of the material film roll, and then insert a new material film roll, and then open the clamping end of the second elastic clamping mechanism. Therefore, the rotating shaft in the utility model is only rotatably connected to the bracket at one end, so that the staff does not need to disassemble the rotating shaft during the disassembly and assembly process, thereby facilitating the replacement of the material film roll.
