DETAILED DESCRIPTION
[0026] The present utility model will be further described in detail below in combination with the drawings.
[0027] Referring to Figure 1 , Figure 2 A book cover film covering device comprises a film covering machine body 1 and an unloading frame 2, the unloading frame 2 comprises two support frames 21 fixed to the top of the film covering machine body 1 respectively, a support shaft 22 is horizontally arranged between the two support frames 21, and the two ends of the support shaft 22 respectively pass through the corresponding support frames 21 and are rotationally connected with the corresponding support frames 21.
[0028] Referring to Figure 1 , Figure 2A plurality of supporting frames 21 are arranged between the two supporting shafts 22, and each supporting frame 23 is fixedly connected with the supporting shaft 22 through a pair of connecting rods 24. The plurality of supporting frames 23 are equidistantly arranged along the circumferential direction of the supporting shaft 22. Meanwhile, two ends of each supporting frame 23 are horizontally rotatably connected with a feeding shaft 25, and a limiting jaw 26 is fixedly connected with each feeding shaft 25. The limiting jaw 26 is used for clamping and limiting the corresponding end of the plastic film roll.
[0029] With reference to Figure 1 , Figure 2 The supporting shaft 22 and one of the supporting frames 21 are provided with a locking piece 3. When the supporting shaft 22 rotates clockwise or counterclockwise and one of the supporting frames 23 moves to the position directly below the supporting shaft 22, the locking piece 3 is used to limit the rotation of the supporting shaft 22.
[0030] Since a plurality of plastic film rolls can be fixed at the positions around the supporting shaft 22, that is, the plastic film roll located at the position directly below the supporting shaft 22 is used for feeding operation, and the remaining plastic film rolls are in a waiting state. When the plastic film roll located at the position directly below the supporting shaft 22 is used up, the supporting shaft 22 can be controlled to rotate clockwise or counterclockwise, and one of the plastic film rolls moves to the position directly below the supporting shaft 22. Then, the plastic film roll can be used for feeding operation, at this time, the film coating device can be started and continue to perform the film coating operation. Subsequently, the worker can disassemble and replace the used plastic film roll during the normal operation of the film coating device, effectively shortening the downtime of the film coating device, thereby improving the production efficiency.
[0031] With reference to Figure 3 , Figure 4 The locking piece 3 comprises a limiting tooth ring 31 fixedly sleeved on the end of the supporting shaft 22. The supporting frame 21 is horizontally slidably connected with a limiting cylinder 32 through a guide piece 4. The limiting cylinder 32 is coaxially arranged with the supporting shaft 22, and can be sleeved on the limiting tooth ring 31. Meanwhile, the inner side wall of the limiting cylinder 32 is provided with a limiting tooth groove 33. When the limiting cylinder 32 is sleeved on the limiting tooth ring 31, the limiting tooth ring 31 is engaged with the limiting tooth groove 33 to limit the rotation of the supporting shaft 22.
[0032] With reference to Figure 3 , Figure 4 The guide piece 4 comprises a pair of guide rods 41 horizontally fixed on the supporting frame 21, and the pair of guide rods 41 are symmetrically arranged on the two sides of the limiting tooth ring 31. A guide ring 42 is fixedly sleeved on the limiting cylinder 32, and a pair of guide holes 43 are arranged through the guide ring 42. The pair of guide rods 41 respectively pass through the corresponding guide holes 43.
[0033] With reference to Figure 3 , Figure 4A return spring 5 is provided between the guide ring 42 and the support frame 21. One end of the return spring 5 is fixedly connected to the guide ring 42 and the other end is fixedly connected to the support frame 21. The return spring 5 is used to pull the limiting cylinder 32 toward the support frame 21 and to make the limiting cylinder 32 fit onto the limiting tooth ring 31 so that the limiting tooth ring 31 meshes with the limiting tooth groove 33, thereby improving the locking stability of the support shaft 22.
[0034] Reference Figure 3 , Figure 4 The inner wall of the limiting cylinder 32 is fixedly connected to a positioning ring 6. When the limiting cylinder 32 is sleeved on the limiting toothed ring 31 and the positioning ring 6 abuts against the support shaft 22, the limiting toothed ring 31 meshes with the limiting toothed groove 33 to determine the locking position of the limiting cylinder 32, so as to prevent the limiting cylinder 32 from sliding excessively and causing the limiting toothed ring 31 to separate from the limiting toothed groove 33.
[0035] Reference Figure 3 , Figure 4 A pair of guide rods 41 are respectively fixedly fitted with limiting rings 7 at the ends away from the support frame 21. When the limiting cylinder 32 moves away from the support frame 21 and the guide ring 42 comes into contact with the limiting ring 7, the limiting tooth ring 31 separates from the limiting tooth groove 33, thereby determining the unlocking position of the limiting cylinder 32 to prevent the guide rod 41 from sliding out of the guide hole 43.
[0036] Pulling the limiting cylinder 32 causes the guide ring 42 to move away from the support frame 21. When the guide ring 42 abuts against the limiting ring 7, the limiting toothed ring 31 separates from the limiting toothed groove 33, thereby unlocking the support shaft 22. When the limiting cylinder 32 is released, the guide ring 42, under the action of the return spring 5, causes the limiting cylinder 32 to move towards the support frame 21, and the limiting cylinder 32 is fitted onto the limiting toothed ring 31. When the positioning ring 6 abuts against the end of the support shaft 22, the limiting toothed ring 31 engages with the limiting toothed groove 33, thereby locking the support shaft 22.
[0037] Reference Figure 3 , Figure 4 The end of the limiting cylinder 32 away from the support frame 21 is fixedly connected to a control handle 8, so that the staff can pull the limiting cylinder 32 to move quickly, thereby realizing the quick unlocking of the support shaft 22.
[0038] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
