By connecting the pressing roller and the pressure roller with elastic components, the pressing roller and the pressure roller can better fit the product surface, preventing wrinkles and improving adhesion, thereby improving the coating effect. However, this patent still has the following problems in actual use:

[0004] By connecting the pressure roller and the pressure roller with elastic components, the pressure roller and the pressure roller can fit the product surface better, prevent wrinkles, improve adhesion, and thus improve the coating effect. However, in the current technology, some coating devices lack limiting mechanisms and can usually only perform coating processing on materials of fixed size, resulting in low flexibility of use.

[0005] A PE protective film coating device is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a PE protective film coating device to solve the problem mentioned in the background art that some coating devices in the existing technology lack limiting mechanisms and can usually only perform coating processing on objects of fixed size, resulting in low flexibility of use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a PE protective film coating device, comprising a housing, wherein a conveying device is provided on the top surface of the housing;

[0008] A connecting plate is symmetrically installed on one side surface of the housing. A power roller is rotatably connected to the middle of the surface of the connecting plate near the top. An air outlet pipe is fixedly installed on one side of the power roller. Several air outlet nozzles are connected through the bottom surface of the air outlet pipe. A guide rod is provided below the power roller. The two sides of the guide rod are fixedly connected to the connecting plate.

[0009] Also includes:

[0010] The connecting plate has a groove on one side of its interior, and an adjustment limiting component is provided inside the groove.

[0011] The adjusting limit assembly includes an electric push rod that is fixedly connected to the groove;

[0012] A connecting block is fixedly connected to the top surface of the electric push rod.

[0013] Preferably, a double-ended lead screw is rotatably connected to one side surface of the connecting block, and a threaded sleeve is threaded onto the surface of the double-ended lead screw, with a limit rod penetrating the side surface of the threaded sleeve near the top.

[0014] Preferably, stabilizing blocks are fixedly connected to both sides of the limiting rod, and the bottom surface of the stabilizing blocks is fixedly connected to the connecting block.

[0015] Preferably, the bottom surface of the connecting block is fixedly connected to a rubber corrugated plate, the bottom surface of the rubber corrugated plate is fixedly connected to the groove, and the top surface of the stabilizing block is fixedly connected to the rubber corrugated plate.

[0016] Preferably, a limiting plate is fixedly connected to one side surface of the threaded sleeve.

[0017] Preferably, the limiting plate has a connecting groove inside, and a plurality of return springs are fixedly installed inside the connecting groove. A stop block is fixedly connected to the bottom surface of the return spring, and the stop block is slidably connected to the connecting groove.

[0018] Preferably, the stop is made of ultra-high molecular weight polyethylene.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This PE protective film coating device, by setting an adjusting limit component, can be flexibly adjusted according to the size of the object to be coated to adapt to the coating requirements of different sizes. At the same time, by setting a return spring and a stop block, the stop block is always in contact with the top surface of the conveying device, thereby facilitating the coating process for workpieces of different heights. The specific details are as follows:

[0020] 1. By setting an adjustable limit assembly, after measuring the size and height of the covering using an infrared rangefinder, the infrared rangefinder transmits the data to the control terminal. The control terminal then activates an electric push rod, causing its output to lift the connecting block, double-ended lead screw, threaded sleeve, and limit plate. Simultaneously, the control terminal activates a stepper motor fixedly connected to the double-ended lead screw. The stepper motor is mounted on one side of the connecting block and located inside a groove. The stepper motor activates the double-ended lead screw, causing its rotation to move the threaded sleeves on both sides towards the center or to the sides. The threaded sleeves are connected to the limit rod, which is fixedly connected to the stabilizing block. The stabilizing block is fixedly connected to the connecting block. Through the cooperation of the limit rod, stabilizing block, and connecting block, the threaded sleeves can be adjusted... The limiting mechanism allows the double-ended lead screw to rotate, which in turn moves the threaded sleeve. This movement of the threaded sleeve then moves the limiting plate and the stop block, enabling flexible adjustment based on the size of the material to accommodate different film-coating requirements. Simultaneously, the stepper motor generates vibration during operation. High-elasticity damping pads are installed between the electric push rod and the connecting block to absorb vibration through their elastic deformation. Furthermore, if the electric push rod and connecting block are currently connected by bolts, "anti-loosening damping bolts" are used to prevent bolt loosening due to vibration and to buffer vibration through the elasticity of spring washers, ensuring the normal operation of the electric push rod. Additionally, a fan or other heat dissipation components are installed inside the groove to dissipate the heat generated by the stepper motor during operation.

[0021] 2. By setting a reset spring and a stop, when the electric push rod drives the whole thing to rise, the limit plate will also rise along with the whole thing. The reset spring inside the limit plate will slowly return to its original position during the rise of the limit plate, which will drive the stop to fall. This ensures to a certain extent that even when the limit plate rises, there are still parts that are in contact with the top surface of the conveying device, thus limiting the movement of the covered object.

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a PE protective film coating device, including a housing 1, a conveying device 2 disposed on the top surface of the housing 1; a connecting plate 3 symmetrically mounted on one side surface of the housing 1, a power roller 4 rotatably connected to the middle of the connecting plate 3 near the top surface, an air outlet pipe 5 fixedly mounted on one side of the power roller 4, a plurality of air outlet nozzles 6 connected through the bottom surface of the air outlet pipe 5, a guide rod 7 disposed below the power roller 4, and the two sides of the guide rod 7 fixedly connected to the connecting plate 3; further comprising: a groove 8 formed on one side of the inner side of the connecting plate 3, an adjusting and limiting component 9 disposed inside the groove 8; wherein, the adjusting and limiting component 9 includes an electric push rod 901 fixedly connected to the groove 8; wherein, a connecting block 902 is fixedly connected to the top surface of the electric push rod 901, such as Figure 1-5 As shown, by setting the adjustment limit component 9, it is possible to flexibly adjust according to the size of the object to be coated to meet the coating requirements of different sizes. At the same time, by setting the return spring 11 and the stop block 12, the stop block 12 is always in contact with the top surface of the conveying device 2, which makes it easy to coat workpieces of different heights. Meanwhile, the housing 1, the conveying device 2, the connecting plate 3, the power roller 4 and the guide rod 7 are components of the coating device in the prior art. The coating device is the prior art and its working principle and power connection are the same as the prior art. At the same time, the air nozzle 6 is set to be perpendicular to the surface of the object to be coated in order to more effectively remove dust and impurities from the surface of the object to be coated.

[0030] A double-ended lead screw 903 is rotatably connected to one side surface of the connecting block 902. A threaded sleeve 904 is threaded onto the surface of the double-ended lead screw 903. A limit rod 905 is connected through the top side surface of the threaded sleeve 904. Stabilizing blocks 906 are fixedly connected to both sides of the limit rod 905. The bottom surface of the stabilizing block 906 is fixedly connected to the connecting block 902. A rubber corrugated plate 907 is fixedly connected to the bottom surface of the connecting block 902. The bottom surface of the rubber corrugated plate 907 is fixedly connected to the groove 8. The top surface of the stabilizing block 906 is fixedly connected to the rubber corrugated plate 907. A limit plate 908 is fixedly connected to one side surface of the threaded sleeve 904. Figure 2 , 3 As shown in Figure 5, the electric push rod 901 is activated via the control terminal, causing its output end to drive the connecting block 902, the double-ended lead screw 903, the threaded sleeve 904, and the limiting plate 908 to rise. Simultaneously, a stepper motor fixedly connected to the double-ended lead screw 903 is activated via the control terminal. The stepper motor is mounted on one side of the connecting block 902 and located inside the groove 8. The stepper motor activates the double-ended lead screw 903, causing its rotation to move the threaded sleeves 904 on both sides towards the center or to the sides. The threaded sleeves 904 are connected to the limiting rod 905, which is fixedly connected to the stabilizing block 906. The stabilizing block 906 is fixedly connected to the connecting block 902. Through the coordination between the limiting rod 905, the stabilizing block 906, and the connecting block 902… The mechanism allows for the limiting of the threaded sleeve 904, enabling the double-ended lead screw 903 to rotate and move the threaded sleeve 904. The movement of the threaded sleeve 904, in turn, moves the limiting plate 908 and the stop block 12, allowing for flexible adjustment based on the size of the material to accommodate different coating requirements. A rubber corrugated tube can be fitted onto the double-ended lead screw 903 for protection. The rubber corrugated plates 907 on the stabilizing block 906 and connecting block 902 are fixedly connected to the groove 8, effectively reducing dust entry into the groove and preventing damage to the electric actuator 901. The electric actuator 901, model SK25H, has good dust and water resistance.

[0031] The limiting plate 908 has a connecting groove 10 inside, and several return springs 11 are fixedly installed inside the connecting groove 10. A stop block 12 is fixedly connected to the bottom surface of each return spring 11, and the stop block 12 is slidably connected to the connecting groove 10. The stop block 12 is made of ultra-high molecular weight polyethylene. Figure 4As shown, by setting a return spring 11 and a stop block 12, when the electric push rod 901 drives the whole to rise, the limiting plate 908 will also rise along with the whole. The return spring 11 inside the limiting plate 908 will slowly return to its original position during the rising process of the limiting plate 908, thereby driving the stop block 12 to fall. This ensures to a certain extent that even when the limiting plate 908 rises, there are still parts that are in contact with the top surface of the conveying device 2, thus limiting the covering of the object. At the same time, the stop block 12 is made of ultra-high molecular weight polyethylene, which reduces the friction between it and the conveying device 2.

[0032] Working principle: Before using this PE protective film coating device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5 As shown, firstly, by setting the adjustment limit component 9, after measuring the size and height of the covering using an infrared rangefinder, the infrared rangefinder transmits the data to the control terminal. Then, the control terminal activates the electric push rod 901, causing the output end of the electric push rod 901 to drive the connecting block 902, the double-ended lead screw 903, the threaded sleeve 904, and the limit plate 908 to rise. Simultaneously, the control terminal activates the stepper motor fixedly connected to the double-ended lead screw 903. The stepper motor is installed on one side of the connecting block 902 and located inside the groove 8. The stepper motor activates the double-ended lead screw 903, causing its rotation to drive the threaded sleeves 904 on both sides to move towards the center or to the sides. At the same time, the threaded sleeves 904 are connected to the limit rod 905 through the thread, limiting the movement. Rod 905 is fixedly connected to stabilizing block 906, and stabilizing block 906 is fixedly connected to connecting block 902. Through the cooperation between limiting rod 905, stabilizing block 906, and connecting block 902, the threaded sleeve 904 can be limited. This allows the double-ended lead screw 903 to rotate, driving the threaded sleeve 904 to move. The movement of the threaded sleeve 904, in turn, drives the limiting plate 908 and stop block 12 to move, enabling flexible adjustment according to the size of the coated material to meet different coating requirements. Simultaneously, the stepper motor generates vibration during operation. High-elasticity vibration-damping pads, such as nitrile rubber pads or silicone pads, with a thickness of 3-5 mm and a hardness of 50-70, are installed between the electric push rod 901 and connecting block 902. A. The elastic deformation of the gasket absorbs vibration. In the prior art, when the electric push rod 901 and the connecting block 902 are connected by bolts, "anti-loosening and vibration-damping bolts" such as those with spring washers and nylon anti-loosening nuts are used. This not only prevents the bolts from loosening due to vibration, but also buffers the vibration through the elasticity of the spring washers, thereby ensuring the normal use of the electric push rod 901. At the same time, a fan or other heat dissipation components are installed inside the groove 8 to dissipate the heat generated when the stepper motor is running.

[0033] Secondly, by setting a reset spring 11 and a stop block 12, when the electric push rod 901 drives the whole body to rise, the limit plate 908 will also rise along with the whole body. The reset spring 11 inside the limit plate 908 will slowly return to its original position during the rise of the limit plate 908, which will drive the stop block 12 to fall. This ensures to a certain extent that even when the limit plate 908 rises, there are still parts that are in contact with the top surface of the conveying device 2, thereby limiting the covering of the object.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
