DETAILED DESCRIPTION

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-6 This utility model provides the following technical solution: a degradable packaging box coating device, comprising a device body 1, a limiting mechanism for restricting the position of the packaging box on the top of the device body 1, the limiting mechanism including a guide plate 4 rotatably mounted on the end of the device body 1, and a limiting plate 2 rotatably mounted on the end of the guide plate 4, and a squeezing roller 3 on the inner wall of the limiting plate 2, a slider 31 slidably connected to the inner wall of the limiting plate 2 fixedly mounted on the end of the squeezing roller 3, and a squeezing spring 32 on the outer wall of the slider 31, and a groove 21 corresponding to the slider 31 on the outer wall of the squeezing plate, the top of the squeezing plate being fixedly... The device is equipped with an adjusting block 22. The guide plate 4 is telescopic and is symmetrically arranged at the end of the main body 1. The guide plate 4 is inclined. The limiting plate 2 is symmetrically arranged at the top of the main body 1. The limiting plate 2 has an inverted U-shaped cross-section. The outer wall of the limiting plate 2 connected to the guide plate 4 is higher than the outer wall of the extrusion plate. Two sets of adjusting blocks 22 are symmetrically arranged at the top of the limiting plate 2. Multiple sets of extrusion rollers 3 are equally spaced at the bottom of the extrusion plate. The sliders 31 are symmetrically arranged at both ends of the extrusion rollers 3. The length of the groove 21 corresponds to the sliding range of the extrusion rollers 3.

[0026] When applying glue to the packaging box, the main body 1 of the device is started. The packaging box is first transported by the conveyor belt. When the packaging box passes the guide plate 4, the guide plate 4 guides the packaging box to the ends of the two sets of limiting plates 2. The conveyor belt continues to transport the packaging box into the bottom of the limiting plate 2. While the packaging box is being transported, multiple sets of extrusion rollers 3 continuously extrude and limit the packaging box under the extrusion spring 32, restricting the packaging box to be transported within the preset track of the two sets of extrusion plates. The packaging box is transported to the glue application area where the main body 1 of the device applies glue to the packaging box. The extrusion rollers 3 can slide the slider 31 in the slide groove 21 according to the thickness of the packaging box, thereby limiting the packaging box while also allowing for free adjustment according to the thickness of the packaging box, ensuring that the packaging box will not shift during the glue application process and improving the glue application quality.

[0027] Example 2: Based on Example 1, an adjustment mechanism is also disclosed, the specific structure of which is as follows: The outer wall of the main body 1 of the device is provided with an adjustment mechanism for adjusting the extrusion plate. The adjustment mechanism includes a mounting plate 5 fixedly installed on the outer wall of the main body 1 of the device, and a bidirectional threaded rod 6 that is threadedly connected to the adjustment block 22 is rotatably installed on the outer wall of the mounting plate 5. A connecting block 61 is fixedly installed at the end of the bidirectional threaded rod 6, and a rotating shaft 62 is fixedly installed on the outer wall of the connecting block 61. A rotating disk 51 is rotatably installed on the outer wall of the mounting plate 5, and a handle 52 is fixedly installed on the outer wall of the rotating disk 51. A connecting rod 7 that is rotatably connected to the rotating shaft 62 is rotatably installed on the outer wall of the handle 52. Two sets of bidirectional threaded rods 6 are provided corresponding to the adjustment block 22, and the length of the bidirectional threaded rod 6 is greater than the distance between the two sets of mounting plates 5. The distance between the handle 52 and the center of the rotating disk 51 is the same as the distance between the rotating shaft 62 and the center of the bidirectional threaded rod 6. The two ends of the connecting rod 7 are rotatably connected to the two sets of rotating shafts 62 respectively, and the length of the connecting rod 7 corresponds to the distance between the two sets of rotating shafts 62.

[0028] When applying glue to packaging boxes of different specifications, firstly, by rotating the handle 52 located on the outer wall of the mounting plate 5, the handle 52 drives the rotating disk 51 to rotate, thereby causing the connecting rod 7 to drive the connecting blocks 61 located at both ends of the connecting rod 7 to rotate. The connecting blocks 61 drive the two sets of bidirectional threaded rods 6 to rotate simultaneously, causing the two sets of adjusting blocks 22 to slide on the outer wall of the bidirectional threaded rods 6, thereby driving the movement of the limiting plate 2 until it is adjusted to a position suitable for the packaging box specifications. Then, stop rotating the handle 52. This allows the two sets of limiting plates 2 to adjust the spacing according to different packaging box specifications, further improving the practicality and flexibility of the limiting mechanism.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
