[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] This utility model provides a technical solution: such as Figures 1 to 3 As shown in this embodiment, a gold-sand milky white PE environmentally friendly high-precision film composite coating device includes a fixed frame 1. A movable seat 2 is symmetrically slidably installed in the middle of the fixed frame 1. A locking block 3 is installed on the top of the movable seat 2. A U-shaped groove 4 is opened on one side of the top of the locking block 3. A receiving cavity 5 is opened inside the locking block 3. An inclined cut surface 17 is opened at one end of the locking block 3 corresponding to the position of the U-shaped groove 4. The locking block 3 is replaceable. After coating and laminating two layers of PE environmentally friendly high-precision film raw materials, the sidewalls of the PE environmentally friendly high-precision film are controlled to be squeezed into the U-shaped groove 4. During the conveying process of the PE environmentally friendly high-precision film, the colloid on both sides of the PE environmentally friendly high-precision film will be cut by the inclined cut surface 17 on the U-shaped groove 4. The excess colloid will flow into the receiving cavity 5 through the inclined cut surface 17, which can remove the colloid on both sides of the PE environmentally friendly high-precision film and improve the processing quality of the PE environmentally friendly high-precision film.

[0022] like Figures 1 to 3 As shown, a limiting rod 6 is symmetrically fixedly installed in the middle of the fixed frame 1, and limiting holes 7 are symmetrically opened at both ends of the movable seat 2. The limiting holes 7 are slidably connected to the limiting rod 6. A bidirectional screw 8 is rotatably installed in the middle of the fixed frame 1 through a bearing. A motor 9 is fixedly installed on one side of the fixed frame 1 corresponding to the position of the bidirectional screw 8. The output end of the motor 9 is fixedly connected to one end of the bidirectional screw 8. The two movable seats 2 are respectively threaded to the middle of both ends of the bidirectional screw 8.

[0023] The motor 9 drives the bidirectional screw 8 to rotate. The two moving seats 2 can be driven to move towards each other or away from each other along the trajectory of the limit rod 6 through the threaded connection between the moving seats 2 and the bidirectional screw 8. This controls the sidewall of the PE environmentally friendly high-precision film to be squeezed inside the U-shaped groove 4, which can process PE environmentally friendly high-precision films of various widths.

[0024] like Figures 1 to 3 As shown, the top of the movable seat 2 is symmetrically provided with insertion holes 10, and the bottom of the locking block 3 is symmetrically fixedly installed with insertion rods 11, which are slidably inserted into the insertion holes 10.

[0025] The movable base 2 and the card block 3 can be assembled by inserting the insert rod 11 on the card block 3 into the insertion hole 10 of the movable base 2.

[0026] like Figures 1 to 3 As shown, a guide pipe 12 is fixedly installed at the bottom of the card block 3, and the end of the guide pipe 12 is connected to the storage cavity 5.

[0027] After the colloid on both sides of the PE environmentally friendly high-precision film flows into the storage cavity 5 along the inclined cut surface 17, the colloid inside the storage cavity 5 can be discharged through the guide tube 12.

[0028] like Figures 1 to 3 As shown, positioning rollers 13 are installed at both ends of the fixing frame 1. The PE environmentally friendly high-precision film is positioned between the two positioning rollers 13. Fixing rods 14 are symmetrically fixedly installed on both sides of the fixing frame 1. Mounting blocks 15 are slidably installed between the two fixing rods 14 on the same side. One of the positioning rollers 13 is rotatably installed at both ends of the fixing frame 1 through bearings, and the other positioning roller 13 is rotatably installed between the two mounting blocks 15 through bearings. A compression spring 16 is sleeved on the outside of the fixing rod 14. One end of the compression spring 16 is fixedly connected to the top of the mounting block 15, and the other end of the compression spring 16 is fixedly connected to the fixing frame 1.

[0029] Since the mounting block 15 is slidably mounted between the two fixed rods 14, PE environmentally friendly high-precision films of different thicknesses can be passed through the two positioning rollers 13. The compression of the mounting block 15 by the compression spring 16 can drive the PE environmentally friendly high-precision film to be stably set between the two positioning rollers 13.

[0030] This utility model provides a gold-sand milky white PE environmentally friendly high-stability film composite coating device, the specific working principle of which is as follows:

[0031] When the device is in use, after coating and laminating two layers of PE environmentally friendly high-precision film raw materials, the PE environmentally friendly high-precision film is passed between the two positioning rollers 13 at both ends of the fixed frame 1. The compression spring 16 squeezes the mounting block 15, which drives the upper positioning roller 13 to squeeze the lower positioning roller 13, so as to stably set the PE environmentally friendly high-precision film between the two positioning rollers 13. The side wall of the PE environmentally friendly high-precision film is set inside the U-shaped groove 4 of the clamping block 3, and the side wall of the PE environmentally friendly high-precision film is controlled to be squeezed inside the U-shaped groove 4. During the conveying process of the PE environmentally friendly high-precision film, the adhesive on both sides of the PE environmentally friendly high-precision film will be cut by the inclined cut surface 17 on the U-shaped groove 4. The excess adhesive will flow into the receiving cavity 5 through the inclined cut surface 17, which can remove the adhesive on both sides of the PE environmentally friendly high-precision film and improve the processing quality of the PE environmentally friendly high-precision film.

[0032] When processing PE environmentally friendly high-precision films of different thicknesses and widths, since the mounting block 15 is slidably installed between the two fixed rods 14, PE environmentally friendly high-precision films of different thicknesses can be passed between the two positioning rollers 13. The compression of the mounting block 15 by the compression spring 16 can drive the PE environmentally friendly high-precision film to be stably set between the two positioning rollers 13. By replacing the clamping blocks 3 with different U-shaped groove 4 sizes, the motor 9 drives the bidirectional screw 8 to rotate. The threaded connection between the moving seat 2 and the bidirectional screw 8 can drive the two moving seats 2 to move towards each other or away from each other along the trajectory of the limit rod 6, and control the side wall of the PE environmentally friendly high-precision film to be squeezed inside the U-shaped groove 4, so that PE environmentally friendly high-precision films of different thicknesses and widths can be processed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
