[0041] Step 7: Replacement completed.

[0042] During the implementation of the present invention, when there is no material on the loading roller 2, one end of the rotating shaft 3 can rotate toward one side, thereby prompting the user to replace the loading roller 2. When replacing, the loading roller 2 can be removed by only sliding the loading roller 2 toward one side, and the replacement operation is simple and convenient.

[0043] When the conveyor belt 10 is conveying materials, in order to ensure that the direction in which the materials enter the conveyor belt 10 is the same as the plane where the conveyor belt 10 is located, the following technical solutions are provided:

[0044] The invention also includes a support frame 1, in which a rotatable threaded rod 4 is installed, and a sliding block 5 is threadedly sleeved on the threaded rod 4, the end of the rotating shaft 3 is inserted into the sliding block 5, and the rotating shaft 3 can rotate in the sliding block 5, the feeding roller 2 is sleeved outside the rotating shaft 3, when the rotating shaft 3 rotates, the feeding roller 2 can rotate accordingly, and a matching block 13 is installed in the sliding block 5, the matching block 13 has two, and is respectively arranged on both sides of the threaded rod 4, and a connecting rod 14 is arranged through the two matching blocks 13, the connecting rod 14 is respectively threadedly engaged with the two matching blocks 13, and when the connecting rod 14 rotates, the two matching blocks 13 can approach / move away from each other, and the connecting rod 1 An end fixing block 15 is fixedly connected to the end of the threaded rod 4, and a movable block 16 that can move up and down is also arranged in the sliding block 5. The movable block 16 is in friction contact with the sliding block 5, and in the absence of external force intervention, the movable block 16 can be in a static state, and the side wall of the movable block 16 is meshed with the end fixing block 15. When the sliding block 5 moves to the lower end position of the threaded rod 4, the movable block 16 can move upward, so that the two matching blocks 13 move in a direction away from the threaded rod 4, and when the sliding block 5 moves to the upper end of the threaded rod 4, the movable block 16 can move downward, so that the two matching blocks 13 are in contact with the surface of the threaded rod 4, and a first spring 6 is arranged between the sliding block 5 and the support frame 1.

[0045] When the above scheme is implemented, as the conveyor belt 10 runs, the threaded rod 4 can rotate accordingly, so that the sliding block 5 can move downward, and the direction in which the material initially enters the conveyor belt 10 is on the plane where the conveyor belt 10 is located, thereby ensuring that as the material on the loading roller 2 decreases, when the material enters the conveyor belt 10, the plane where the material is located is always the same as the plane where the conveyor belt 10 is located, avoiding the situation where the material may be wrinkled due to a certain angle between the material and the conveyor belt 10.

[0046] The material is a film-like material, and the material is wound around the feeding roller 2.

[0047] There are two sliding blocks 5 , each of which cooperates with one end of the rotating shaft 3 . The two sliding blocks 5 can slide synchronously to ensure the stability of the rotating shaft 3 .

[0054] The fixed block 20 and the push block 21 are used in combination to limit the position of the feeding roller 2. The upper surface of the push block 21 has an inclined surface, which can facilitate the feeding roller 2 to pass over the push block 21 when the feeding roller 2 is sleeved on the rotating shaft 3.

[0055] The core shaft 19 can slide a short distance, so that the push block 12 can fix the position of the feeding roller 2.

[0056] An upper toggle rod 27 is fixedly connected to the support frame 1, and a tooth block 8 is arranged below one of the sliding blocks 5. The tooth block 8 has a first single tooth and a second single tooth. The first upper toggle rod 27 can be inserted into the sliding block 5 to push the movable block 16 downward, the second single tooth can be inserted into one of the sliding blocks 5 to push the movable block 16 therein upward, the first single tooth can be inserted into the sliding block 5 to push the insertion rod 25 upward, and a lower toggle rod 9 is arranged below the other sliding block 5, and the lower toggle rod 9 can be inserted into the sliding block 5 to push the movable block 16 therein upward.

[0057] The second rotating shaft 18 is fixedly connected to the rotating plate 11 , and the first rotating shaft 17 is fixedly connected to the connecting block 12 .

[0058] A rotating wheel 7 is fixedly connected to the lower end of the threaded rod 4. The rotation of the rotating wheel 7 drives the rotation of the threaded rod 4. The rotating wheel 7 can be driven by the conveyor belt 10 or by other means.

[0059] As for the rotating shaft 3 and the feeding roller 2 , the rotating shaft 3 may have a rectangular structure, thereby ensuring that the feeding roller 2 and the rotating shaft 3 can rotate synchronously.
