[0031] For details, please refer to Figure 1-Figure 4 A slide rail 16 is fixedly connected to the upper end of the box body 1 , a slider 17 is slidably connected to the slide rail 16 , and the slider 17 is connected to the connecting plate 21 .

[0032] In this embodiment: the upper end of the box body 1 is fixedly connected with a slide rail 16, and a slider 17 is slidably connected to the slide rail 16, and the slider 17 is connected to the connecting plate 21. This design allows the slider 17 to move up and down along the slide rail 16, so as to achieve accurate alignment and closure of the upper mold 6 and the lower mold 22. The sliding connection between the slide rail 16 and the slider 17 ensures smooth and accurate movement, while reducing mechanical wear and improving the overall service life of the equipment. Specifically, the slide rail 16 can be a series of parallel tracks fixed to the box body 1, which are designed to withstand the weight of the slider 17 and the friction force during sliding.

The ratchet 14 is rotatably connected to the side end of the connecting seat 10 through the rotating shaft, and its function is to mesh with the ratchet 13 to realize the rotation of the rotating rod 11. The design of the ratchet 14 should have sufficient strength and wear resistance to withstand the force and friction during the rotation process. The torque spring 15 is connected between the ratchet 14, the torque spring 15 and the connecting seat 10, and its function is to provide an elastic force so that the ratchet 14 can intermittently mesh and release on the ratchet 13, thereby controlling the rotation speed and rhythm of the rotating rod 11. The ratchet 14 and the ratchet 13 are intermittently meshed: this intermittent meshing design allows the ratchet 14 to move intermittently on the ratchet 13, thereby realizing the intermittent rotation of the rotating rod 11. This design can be used to control the speed of the laminating roller 12 to adapt to different production speeds and laminating requirements.

[0040] In this embodiment: the cylinder 7 is a common actuator, which uses compressed air as a power source and drives the connected parts through the reciprocating motion of the piston. In this embodiment, the cylinder 7 is used to drive the closing and separation of the upper mold 6, so as to realize the assembly of the protective film of the plastic frame. The output end of the cylinder 7 is usually a piston or a push rod, which is connected to the upper mold 6 to convert the reciprocating motion of the cylinder 7 into the linear motion of the upper mold 6. This connection method can be achieved by bolts, welding or other fixing devices. The upper mold 6 is a key component in the plastic frame protective film assembly equipment. It is used in conjunction with the lower mold 22 to form and fix the protective film on the plastic frame. The design of the upper mold 6 should ensure precise alignment with the lower mold 22, as well as sufficient strength and wear resistance.

[0041] The working principle and use process of the utility model are as follows: First, start the cylinder 7 to push the upper mold 6 downward so that it is closed with the lower mold 22. When the upper mold 6 is closed, the protective film on the coating roller 12 is stretched and covered on the plastic frame. Keep the closed state for a period of time to ensure that the protective film is firmly attached to the plastic frame. Stop the operation of the cylinder 7, open the upper mold 6, and release the coated plastic frame. Take out the coated plastic frame and carry out the next round of coating operation. Clean the equipment regularly to remove residual film material and dust. Check and lubricate the moving parts of the equipment to keep it in good operating condition. After completing the production task, turn off the cylinder 7 and the power supply, and disconnect the compressed air supply. Keep the equipment in the closed state and wait for the next use.
