However, the pressing structure of the traditional laminating machine has at least the following disadvantages:

[0005] First of all, the traditional laminating machine's pressing structure requires manual pressing, which brings many inconveniences. On the one hand, the labor intensity is high, and the operator needs to pay attention to the pressing situation at all times and adjust the pressure according to the actual situation of the film and the coated object. This not only requires the operator to have certain experience and skills, but also long-term operation is prone to fatigue, affecting work efficiency. On the other hand, the manual pressing method cannot achieve high-speed automated production, which limits the improvement of production efficiency. In addition, manual operation is prone to errors, such as uneven pressure adjustment, improper pressing time, etc., resulting in unstable lamination quality.

[0006] Secondly, the lamination structure of the traditional laminating machine is not convenient for replacing the lamination roller. Due to the complex structure and installation method of the lamination roller, it needs to be disassembled and reinstalled when replaced, which is not only time-consuming, but also easily affects the bonding strength between the film and the coated object. In addition, the inconvenience of replacing the lamination roller also limits the upgrading and optimization of the equipment, and cannot meet the needs of new films and coating materials that are constantly emerging in the market.

Therefore, the driving motor 16 is rotated, which can drive the eccentric wheel 4 to rotate, thereby driving the connecting rod 6 on it that is connected to the eccentric shaft 5 to rotate, and the top end of the connecting rod 6 follows the eccentric shaft 5 to perform a circular motion, and the bottom end thereof also changes position accordingly, achieving a lifting effect.

[0022] In order to limit the displacement space of the connecting rod 6, the utility model has a fixing part 8 fixedly connected to the bottom end of the cavity 2, and the fixing part 8 and the two side walls of the cavity 2 are connected to each other by a supporting part 9. The interior of the fixing part 8 is provided with a movable groove 10 for cooperating with the lifting part 7 and the connecting rod 6, so that the lifting part 7 connected to the bottom end of the connecting rod 6 can only move along the internal space of the movable groove 10 to achieve the lifting effect.

[0023] At the same time, the lifting part 7 passes through the movable groove 10 and extends to the bottom of the box body 1. The bottom end of the lifting part 7 is fixedly connected to a frame body 11 with an opening facing downward. A number of evenly distributed pressing rollers 12 are arranged inside the frame body 11. The middle parts of the front and rear ends of the pressing rollers 12 are both bearing-connected with bearing blocks 13. The bearing blocks 13 and the frame body 11 are connected to each other through a limited position structure 14. A transmission assembly 15 used in conjunction with the pressing roller 12 is arranged below the pressing roller 12, and the front and rear ends of the box body 1 are both fixedly connected to the support feet 30.

[0024] The above-mentioned components together constitute the general appearance structure of the laminating machine pressing structure of the utility model.

[0025] In order to further explain the specific working principle of the laminating machine pressing structure of the utility model, the above-mentioned limiting structure 14 includes an angle groove 18 opened in the bearing block 13, a rod head 19 is arranged inside the angle groove 18, a cavity 20 is opened inside the rod head 19, a telescopic rod 21 is fixedly connected to the interior of the cavity 20, and the end of the telescopic rod 21 away from the cavity 20 is fixedly connected to a connecting piece 22, and the upper and lower ends of the connecting piece 22 are rotatably connected to a rotating plate 23 used in conjunction with the angle groove 18, and a spring 24 is sleeved on the outside of the telescopic rod 21, and the two ends of the spring 24 are respectively fixedly connected to the connecting piece 22 and the cavity 20. A pressing rod 25 is fixedly connected to the side of the connecting piece 22 away from the telescopic rod 21. The pressing rod 25 passes through the frame 11. A through groove 26 for cooperating with the pressing rod 25 is opened on the frame 11. A rod body 27 is arranged on the outside of the pressing rod 25, so that one end of the rod body 27 abuts against the connecting piece 22, and the other end of the rod body 27 is fixedly connected to a fixing plate 28. A threaded block 31 threadedly connected to the outside of the rod body 27 is arranged between the fixing plate 28 and the frame 11. The upper and lower ends of the part of the rod body 27 located in the angle groove 18 are provided with recesses 29 for accommodating the rotating plate 23.

[0026] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when the various components of the limiting structure 14 clamp the bearing block 13, the rotating plate 23 is clamped along the oblique edge of the angle groove 18, and the spring 24 and the telescopic rod 21 are in a relaxed state. At this time, the threaded connection between the threaded block 31 and the rod body 27 is tightened to achieve a fixing effect. When disassembly and assembly is required, the user only needs to twist the threaded block 31 to loosen it from the rod body 27. At this time, the various devices of the limiting structure 14 lose their restraining force and begin to become loose. At this time, the user only needs to press the pressing rod 25, and the pressing rod 25 is forced to move in the direction of the bearing block 13 and squeeze the connecting piece 22 into the interior of the cavity 20. At this time, the connecting piece 22 squeezes the spring 24 and the telescopic rod 21, which shrink under pressure, and the squeezing of the connecting piece 22 synchronously drives the rotating plate 23 to move inward, and one side of it is clamped on the edge of the cavity 20, so that it begins to rotate under force and rotates in the direction of the recess 29 until it is completely received in the recess 29. At this time, its other corner abuts against the outlet of the angle groove 18. At this time, the user can pull out the rod body 27 as a whole. At this time, the pressing roller 12 loses its limiting force and the user can replace it.

[0027] It should be specially noted here that the components described and identified in the text and drawings of the utility model are the key components constituting the utility model, and the remaining non-key components or obvious prior art components, as well as technical features similar to the prior art, are not shown. However, this does not mean that the above-mentioned components do not exist in the utility model, nor can it be interpreted as a practical limitation on the utility model.

[0028] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
