[0003] For example, a plate surface laminating mechanism with the publication number CN213800350U disclosed in a Chinese patent is aimed at the problem that most existing laminating machines cannot cool down the plate immediately after laminating, which greatly reduces the success rate of laminating. The following scheme is now proposed, which includes a bottom frame, the top of which is fixedly connected with two first frames and two second frames, the tops of the two first frames are rotatably connected with a first rotating rod, and one side of the two second frames is rotatably connected with the same second rotating rod, one side of the bottom frame is fixedly connected with a fixed plate, one side of the fixed plate is fixedly connected with a motor, a first worm is fixedly connected to the output shaft of the motor, a first bevel gear is sleeved on the output shaft of the motor, and one side of the first bevel gear is meshingly connected with a second bevel gear. The utility model can cool down the plate immediately after laminating, thereby greatly improving the success rate of laminating.

[0004] Some problems were found when using the above-mentioned existing plate surface coating mechanism. First, the film roll is fixedly installed on the first rotating rod. After the film on the film roll is used up, the first rotating rod needs to be disassembled to replace the new film roll, which is cumbersome and labor-intensive, and wastes a lot of time. Utility Model Content

[0005] The purpose of the utility model is to provide a coating mechanism for processing environmentally friendly plates to solve the existing problems raised in the above-mentioned background technology.

Through the cooperation of the bidirectional threaded shaft and the dovetail slider thread, the rotation of the bidirectional threaded shaft can drive the two support rods to move, and the movement of the support rods can drive the connecting bearing sleeve to move, so as to adjust the distance between the two connecting bearing sleeves. When the distance between the connecting bearing sleeves increases, the connecting bearing sleeves will move out from both ends of the film roll support shaft, releasing the restriction on the film roll support shaft, thereby facilitating the removal of the film roll support shaft and replacing a new film roll.

[0014] 2. Place the replaced film roll support shaft together with the film roll between two connecting bearing sleeves, rotate the two-way threaded shaft in opposite directions to drive the connecting bearing sleeves closer to each other, so that the film roll support shaft is sleeved inside.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a coating mechanism for environmentally friendly plate processing, comprising a main bracket 1, a dovetail slot is provided below the main bracket 1, a bidirectional threaded shaft 104 is rotatably installed in the dovetail slot, two dovetail sliders 201 are symmetrically slidably installed in the dovetail slot, the bidirectional threaded shaft 104 is threadedly matched with the dovetail slider 201, a support rod 2 is fixedly installed below the dovetail slider 201, a collar 202 is fixedly installed at the lower end of the support rod 2, a connecting bearing sleeve 4 is rotatably installed in the collar 202, an extrusion ring 403 is fixedly installed on one side of the connecting bearing sleeve 4, a driven gear 404 is fixedly installed on the other side of the connecting bearing sleeve 4, and a film roll support shaft 5 is sleeved in the connecting bearing sleeve 4.

[0023] The two ends of the film roll support shaft 5 are moved out of the way by the two ends of the film roll support shaft 5, and the restriction on the film roll support shaft 5 is released, so that it is convenient to remove the film roll support shaft 5 and replace it with a new film roll. After replacement, the film roll support shaft 5 is placed between the two connecting bearing sleeves 4, and the reverse rotation of the two-way threaded shaft 104 drives the connecting bearing sleeves 4 to approach each other, so that the film roll support shaft 5 is sleeved inside. At the same time, the connecting bearing sleeve 4 will drive the extrusion ring 403 to move, and the extrusion ring 403 will squeeze the film roll installed on the film roll support shaft 5, so that the film roll is in the center position, avoiding the film roll from sliding left and right due to material discharge, resulting in film coating deviation.

[0024] Among them, in order to achieve the purpose of controlling the unwinding speed of the film roll, the present device is implemented by adopting the following technical scheme: a first bracket 101 is fixedly installed on the front of the main bracket 1, a tension detection roller 102 is rotatably installed on the first bracket 101, a pressure roller 103 is rotatably installed on the first bracket 101 and located in front of the tension detection roller 102, and a rotating disk 105 is fixedly installed at one end of the bidirectional threaded shaft 104.

[0025] The film adhered to the surface of the plate is squeezed by the pressure roller 103 so that the film adheres to the surface of the plate. As the thickness of the film roll decreases with use, the motor unwinding speed will gradually mismatch the plate moving speed. At this time, the film will gradually tighten. The tension detection roller 102 can detect the film tension. When the film tension is too large, a signal will be sent to increase the unwinding speed to avoid excessive surface tension of the film, which may cause the film to be torn. Rotating the rotating disk 105 can drive the bidirectional threaded shaft 104 to rotate.

[0026] Among them, in order to achieve the purpose of film roll unloading, the present device is implemented by adopting the following technical scheme: a fixed seat 3 is fixedly installed on one side of a support rod 2, a driving motor 301 is fixedly installed under the fixed seat 3, a driving gear 302 is fixedly installed on the output end of the driving motor 301, the driving gear 302 and the driven gear 404 cooperate with each other, the connecting bearing sleeve 4 includes a bearing sleeve 401 and a connecting flange 402, the two sides of the inner ring of the bearing sleeve 401 are fixedly connected to the connecting flange 402, a limiting strip 405 is fixedly installed on the inner wall of the driven gear 404, a limiting groove 501 is provided on the outer wall of the film roll support shaft 5, and the limiting strip 405 and the limiting groove 501 cooperate with each other.

[0027] By starting the driving motor 301, the active gear 302 can be driven to rotate. The active gear 302 cooperates with the driven gear 404 to drive the driven gear 404 to rotate. The limit bar 405 cooperates with the limit groove 501 to clamp the film roll support shaft 5 and the driven gear 404 together, so that the rotation of the driven gear 404 will drive the film roll support shaft 5 to rotate. The rotation of the driven gear 404 can drive the film roll support shaft 5 to rotate, thereby driving the film roll to discharge. The bearing sleeve 401 is fixedly connected to the driven gear 404 and the extrusion ring 403 respectively through the connecting flange 402, so that the driven gear 404 and the extrusion ring 403 are rotatably installed on the ring 202.

[0028] The working principle and use process of the utility model: when using, the device needs to be placed in a suitable position, rotating the rotating disk 105 can drive the two-way threaded shaft 104 to rotate, and the rotation of the two-way threaded shaft 104 can drive the support rods 2 to move away from each other, and the movement of the support rod 2 will drive the connecting bearing sleeve 4 to move, thereby increasing the distance between the two connecting bearing sleeves 4, thereby releasing the restriction on the film roll support shaft 5, and the film roll support shaft 5 can be easily removed and replaced. The replaced film roll support shaft 5 is placed between the two connecting bearing sleeves 4, and the reverse rotation of the two-way threaded shaft 104 drives the connecting bearing sleeves 4 to approach each other, thereby the film roll support shaft 5 is sleeved inside, and at the same time, the connecting bearing sleeve 4 will drive the extrusion ring 403 to move, and the extrusion ring 403 will squeeze the film roll installed on the film roll support shaft 5, so that the film roll is in the center position, starting the driving motor 301 will drive the driven gear 404 to rotate, and the rotation of the driven gear 404 will drive the film roll support shaft 5 to rotate, thereby releasing the film and using the pressure roller 103 for lamination operation.
