[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the following description is provided in conjunction with the present invention. Reference Figures 1-4 A coating mechanism for producing plastic sheets is provided. The coating mechanism for producing plastic sheets includes a frame 1, a support plate 101 arranged in a linear array on the inner side of the frame 1, a fixing frame 102 on the top of the frame 1, and a fixing plate 103 on one side of the frame 1. The conveying mechanism includes a conveyor belt 2, a support plate 101 located below the top of the inner side of the conveyor belt 2, and integrally formed skirts 201 on both sides of the conveyor belt 2. The conveyor belt 2 is driven by a first driving member. The oil spraying structure includes an oil storage container 6 installed inside the fixed frame 102. The bottom of the oil storage container 6 is equipped with atomizing nozzles 7 (ultrasonic atomizing nozzles) arranged in a linear array at equal intervals, and the atomizing nozzles 7 are located above the conveyor belt 2. The top of the oil storage container 6 is equipped with a connecting pipe 601, and the oil storage container 6 is connected to an external pressure supply system (air source pressure 0.4MPa) through the connecting pipe 601. The oiling mechanism includes an oiling roller 9 that can contact the conveyor belt 2. The outer surface of the oiling roller 9 is covered with an oil-absorbing material layer 901. The oiling roller 9 is driven by a second drive unit. In application, the oiling process is automated by the cooperation of the conveyor belt 2, the atomizing nozzle 7, and the oiling roller 9, which solves the problem of low efficiency of manual brushing. At the same time, the linear array of atomizing nozzles 7 ensures that the oil mist evenly covers the plastic sheet on the conveyor belt 2. The oil-absorbing material layer 901 on the oiling roller 9 can further spread the oil layer evenly and improve the coating uniformity.

[0019] Reference Figure 1 and Figure 2The fixing bracket 102 has an inverted U-shaped structure with a vertical part and a horizontal part, and the vertical part and the horizontal part are integrally formed. The oil storage container 6 is installed inside the horizontal part. In application, the integrally formed design of the inverted U-shaped fixing bracket 102 enhances the structural stability and provides reasonable installation space for the oil storage container 6, avoiding displacement caused by vibration during the spraying process.

[0020] Reference Figure 3 The first driving component includes a driving roller 4 and a driven roller 5, which are vertically and rotatably mounted inside the frame 1. The conveyor belt 2 is wrapped around the driving roller 4 and the driven roller 5. A first servo motor 3 is mounted on the frame 1. The output shaft of the first servo motor 3 is connected to one end of the driving roller 4. The first servo motor 3 can be controlled by an external PLC control system. The conveying speed can be adjusted within the range of 0.5-3m / min. In application, the combination of the first servo motor 3 driving the driving roller 4 and the driven roller 5 can precisely control the speed of the conveyor belt 2, adapt to the production needs of plastic sheets of different thicknesses, and reduce the risk of slippage.

[0021] Reference Figure 3 and Figure 4 The oil storage container 6 is equipped with a removable and sealing rubber plug 8 on the injection pipe at the top. The sealing rubber plug 8 is made of fluororubber. In application, the design of the removable rubber plug 8 facilitates the quick oil filling and sealing maintenance of the oil storage container 6, reduces downtime, and prevents oil evaporation from polluting the environment.

[0022] Reference Figure 3 and Figure 4 The oil-absorbing material layer 901 is made of polyurethane sponge or ceramic fiber, and the thickness of the oil-absorbing material layer 901 is 3-8mm. In application, the oil-absorbing layer of polyurethane sponge or ceramic fiber has both high adsorption and wear resistance. The thickness of 3-8mm can balance the oil storage volume and coating pressure, and avoid the oil layer being too thick and causing adhesion.

[0023] Reference Figure 1 and Figure 2The second driving component includes a symmetrically arranged rotating support arm 11 that is rotatably mounted on the outside of the frame 1. The roller shaft on the oiling roller 9 is perpendicular to and rotatably mounted on the rotating support arm 11. A second servo motor 10 is mounted on the fixed plate 103. The output shaft of the second servo motor 10 is connected to the rotating support arm 11 for transmission. The second servo motor 10 can be controlled by an external PLC control system. A pressure sensor is integrated on the rotating support arm 11. The roller pressure range of the oiling roller 9 is controlled between 5-20N to achieve real-time adjustment of the pressure under the oiling roller 9. The external PLC control system controls the speed ratio of the servo motors (first servo motor 3 and second servo motor 10) to be constant at 1:1.2 to ensure that the linear speed of the oiling roller 9 is higher than the speed of the conveyor belt 2, so as to achieve oil film extension and smoothing. In application, the linkage design of the rotating support arm 11 and the second servo motor 10 supports the dynamic adjustment of the contact pressure between the oiling roller 9 and the conveyor belt 2, and adapts to the coating requirements of oils with different viscosities.

[0024] The working principle of this utility model is as follows: The plastic sheet to be coated with oil is placed on the conveyor belt 2, with the sheet located inside the skirt belt 201. Then, the first servo motor 3 is started. At this time, the output shaft of the first servo motor 3 drives the drive roller 4 to rotate. Subsequently, the drive roller 4 drives the conveyor belt 2 and the driven roller to perform transmission, and the conveyor belt 2 transports the plastic sheet to be coated with oil. Simultaneously, the external pressure supply system and the second servo motor 10 are started. At this time, the oil in the oil storage container 6 is sprayed onto the passing plastic sheet through the linearly arrayed atomizing nozzles 7 to complete the initial coating. Meanwhile, the second servo motor 10... The output shaft of the servo motor 10 drives the rotating support arm 11 to rotate until the oiling roller 9 inside the rotating support arm 11 can squeeze and rotate to contact the oiled plastic sheet. When the oiled plastic sheet passes under the oiling roller 9, the oiled plastic sheet drives the oiling roller 9 to rotate on the rotating support arm 11, and the oil-absorbing material layer 901 on the oiling roller 9 is spread evenly a second time. This balances the coating pressure and avoids adhesion caused by excessive oil layer thickness, while improving coating uniformity. This facilitates continuous oiling of the plastic sheet and can significantly improve work efficiency, while reducing the safety risks of manual contact with oil.

[0025] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
