[0003] Because the internal stirring mechanism of this device requires additional power to operate during use in order to ensure that the internal adhesive does not easily solidify and remains uniform, this setup increases the energy consumption of the device and raises the operating cost. Therefore, there is an urgent need for an energy-saving light-shielding adhesive coating device. Summary of the Invention

[0004] The purpose of this invention is to provide a light-shielding adhesive coating device.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0020] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0021] A light-shielding adhesive coating device includes a housing 1, in which an extrusion roller 2 and a coating roller 3 are arranged side by side, with the extrusion roller 2 located above the coating roller 3. The coating roller 3 has rotating shafts I4 extending to the outside of the housing 1 at both ends, with the left rotating shaft I4 connected to a motor 5.

[0022] Gears I6 are provided on the rotating shafts I4 on the outer side of the housing 1. An internal gear ring 7 is provided on the left side of the housing 1, which meshes with the gears I6. Gears II8 are provided on both sides of the bottom of the opening of the internal gear ring 7, which mesh with it. A drive rod 9 connected to the corresponding gear II8 is provided inside the housing 1. A stirring paddle 10 is provided on the drive rod 9 inside the housing 1. The rotating shaft I4 and the two sets of drive rods 9 form an isosceles triangle. The rotating shaft I4 is located above the drive rod 9, so that the rotating shaft I4 and the drive rod 9 can position the internal gear ring 7 through the gears I6 and II8, preventing the internal gear ring 7 from swinging up and down or back and forth. At the same time, since there are circular limiting plates 13 on the rotating shafts I4 and drive rods 9 on both sides of the internal gear ring 7, the limiting plates 13 can restrict the internal gear ring 7 from horizontal displacement on the above components.

[0023] When the motor 5 drives the rotating shaft I4 to rotate the coating roller 3, the rotating shaft I4 will also drive the gear II8 through the gear I6 and the internal gear ring 7 to drive the two sets of drive rods 9 to rotate, so that the drive rods 9 drive the stirring paddle 10 to stir the glue in the box 1 so that it is not easy to solidify and to ensure its uniformity.

[0024] The extrusion roller 2 includes a cylinder 21, with a rotating shaft II 22 at both ends. A boss 23 is provided on the right side of the top of the housing 1 to fix the right rotating shaft II 22. A gear III 25 that meshes with the right gear I 6 is provided at the end of the rotating shaft II 22 outside the boss 23. An annular positioning plate 24 is sleeved on the right end of the cylinder 21 on the same side as the boss 23. A cylinder 26 is sleeved on the cylinder 21 outside the positioning plate 24. An annular seat 27 that locks and fixes the cylinder 26 to the cylinder 21 is screwed onto the left rotating shaft II 22. An internal thread is provided on the inner side wall of the opening of the annular seat 27, and an external thread that is screwed into the corresponding rotating shaft II 22 is provided on the outer side wall.

[0025] like Figure 1 , 2 As shown, an L-shaped plate 11 for fixing the motor 5 is provided on the top of the outer side wall of the housing 1. The top of the internal gear ring 7 is located in the opening formed between the L-shaped plate 11 and the side wall of the housing 1. The annular seat 27 is provided on the same side as the motor 5.

[0026] like Figure 2As shown, a support base 12 is provided on the top of the box body 1. The top of the support base 12 is provided with an arc-shaped notch for supporting the lower half of the ring seat 27. The support base 27 is fixed to the top of the side wall of the box body 1 by bolts. The ring seat 27 and the positioning plate 24 are located on both sides of the cylinder 21, respectively.

[0027] Since the extrusion roller 2 is only supported at one end by the boss 23, its stability is easily insufficient. In this embodiment, the other end of the extrusion roller 2 is supported by the support seat 12. While improving the stability of the extrusion roller 2, when the motor 5 drives the coating roller 3 to rotate through the rotating shaft I4, the rotating shaft I4 also drives the right rotating shaft II22 to rotate in the bearing in the boss 23 through the gear I6 and gear III25. At this time, the right rotating shaft II22 drives the cylinder 21 and the cylinder 26 to drive the left rotating shaft II22 to rotate together. This realizes that the motor 5 drives the coating roller 3 and the extrusion roller 2 to rotate in different directions at the same time. The left rotating shaft II22 drives the annular seat 27 to roll in the arc-shaped notch in the support seat 12 to prevent the support seat 12 from affecting the normal rotation of the extrusion roller 2.

[0028] The method of using this invention is as follows: The gap between the extrusion roller 2 and the coating roller 3 is adjusted according to the thickness of the fabric to be coated. Specifically, a cylinder 26 of the corresponding diameter is selected and fitted onto the cylinder 21 from the left side, held in place by the positioning plate 24 on the right side. Simultaneously, an annular seat 27 is screwed onto the left rotating shaft II 22. The cylinder 26 is locked and fixed onto the cylinder 21 by the annular seat 27 and the positioning plate 24. At this point, the gap between the bottom end of the cylinder 26 and the top end of the coating roller 3 just meets the production requirements. Next, a support seat 12 is installed on the top left side of the housing 1. The arc-shaped notch at the top of the support seat 12 is located at the bottom of the annular seat 27 to provide support. The support seat 12 is then locked and fixed to the top of the housing 1 by bolts. During the above process, the cylinder 26 can be replaced as required to adjust the gap between the extrusion roller 2 and the coating roller 3 to meet the production requirements of different product specifications. Furthermore, after prolonged wear, only the cylinder 26 needs to be replaced to save on replacement costs. The cylinder 26 can also be disassembled for cleaning and other tasks.

[0029] When the motor 5 drives the coating roller 3 to rotate via the rotating shaft I4, the rotating shaft I4 also drives the gear III25 via the right gear I6 to drive the right rotating shaft II22 to rotate on the bearing in the boss 23. At this time, the rotating shaft II22 drives the cylinder 21 and the cylinder 26 to rotate together. The cylinder 21 also drives the ring seat 27 to rotate in the arc-shaped notch at the top of the support seat 12 via the left rotating shaft II22. This allows the motor 5 to drive the coating roller 3 and the extrusion roller 2 to rotate in different directions at the same time, so that the coating roller 3 and the extrusion roller 2 can drive the product between them to move. At the same time, the rotating coating roller 3 drives the light-blocking adhesive in the box 1 to complete the coating work on the product.

[0030] When the motor 5 drives the rotating shaft I4 to rotate, the rotating shaft I4 will also drive the gear II8 through the gear I6 and the internal gear ring 7 to drive the two sets of drive rods 9 to rotate, so that the drive rods 9 drive the stirring paddle 10 to stir the glue in the box 1 so that it is not easy to solidify and to ensure its uniformity.

[0031] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
