DETAILED DESCRIPTION

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0020] like Figure 1 and Figure 2As shown, the utility model provides a multi-layer coating device, including a body 1, a guide module 2 and a coating module 3, both of which are arranged on the body 1, and a gap 4 for allowing a film material 5 to pass through is provided between the guide module 2 and the coating module 3, and the coating module 3 includes at least two coating heads 31, and the output ends of at least two coating heads 31 are both facing the gap 4, and at least two coating heads 31 spray the same / different coatings on the film material 5 in the gap 4 in turn.

[0021] During operation, the film material 5 is transported through the gap 4 between the guide module 2 and the coating module 3. The guide module 2 drives the film material 5 to continuously move. The film material 5 is preferably coated by the coating module 3 at the position in the gap 4. Because the present invention has multiple coating heads 31, and the multiple coating heads 31 sequentially apply coating to the film material 5, the film material 5 will be coated with multiple layers of coating at once after passing through the gap 4.

[0022] The utility model is suitable for the situation where the components of multi-layer coatings do not interfere with each other. After the multi-layer coating is completed at one time, it is transmitted to the outside for drying, thereby improving the coating efficiency and reducing the number of required coating equipment.

[0023] In this embodiment, the coating module 3 includes a translation cylinder 32, a translation seat 33 and a translation guide rail 34. At least two coating heads 31 are installed on the translation seat 33. The translation seat 33 is slidably set on the translation guide rail 34. The translation cylinder 32 drives the translation seat 33 and is used to drive the translation seat 33 close to or away from the guide module 2.

[0024] That is, the present invention controls the width of the gap 4 by driving the translation seat 33 to move back and forth through the translation cylinder 32, thereby effectively achieving the width adjustment effect, so that the present invention can be adaptively adjusted according to the requirements of the thickness of the film material 5, the required thickness of the coating layer, etc., thereby improving the flexibility of the present invention.

[0025] Specifically, each coating head 31 is mounted on a translation base 33, and the angles between each coating head 31 and the top of the translation base 33 are different. This means that the angle of each coating head 31 is changed to adjust the output angle of each coating head 31. This allows the coating of each coating head 31 to be sequentially applied to the film material 5, ensuring that the next coating layer is applied after the first coating layer is applied.

[0026] Specifically, a first rotating member is provided at one end of the coating head 31 away from the output end, and a second rotating member is provided at the translation seat 33 , and the first rotating member and the second rotating member are rotationally connected.

[0027] In actual use, the first rotating member and the second rotating member are both hinged seats, and the two are rotatably connected through a rotating shaft, so that the staff can adjust the angle of each coating head 31 according to actual needs, thereby adjusting the time interval between adjacent coatings.

[0028] Specifically, the coating module 3 also includes a lifting drive 35 and an adjustment block 36. The lifting drive 35 is used to drive the adjustment block 36 to rise and fall. A first inclined surface 310 is provided on one side of the adjustment block 36, and the translation seat 33 is provided with a second inclined surface 311. The first inclined surface 310 conflicts with the second inclined surface 311.

[0029] Specifically, the present invention uses the lifting drive 35 to control the adjustment block 36 to rise and fall relative to the translation seat 33, thereby changing the position of the second inclined surface 311, against which the first inclined surface 310 abuts. This change in the position of the adjustment block 36 adjusts the travel of the translation seat 33, thereby achieving highly precise variation in the gap 4. After the first inclined surface 310 abuts the second inclined surface 311, the thrust of the translation cylinder 32 ensures that the translation seat 33 always tends to move toward the adjustment block 36, stabilizing the position of the translation seat 33 and preventing it from retreating.

[0030] In actual use, the lifting drive member 35 includes a lifting motor 37, a lifting transmission rod 38, and a lifting guide rail 39. The lifting guide rail 39 is disposed on the machine body 1. The adjustment block 36 is slidably disposed on the lifting guide rail 39. The lifting motor 37 drives the lifting transmission rod 38, which is screwed to the adjustment block 36. The lifting motor 37 and the lifting transmission rod 38 cooperate to achieve high-precision adjustment of the height of the adjustment block 36, thereby achieving high-precision adjustment of the width of the gap 4.

[0031] In this embodiment, the machine body 1 is further provided with a collecting tank 6, which is used to collect the paint dripping from the coating head 31 / film material 5 to prevent the paint from splashing to different locations, thereby ensuring a clean environment.

[0032] In this embodiment, the guide module 2 includes a guide roller 21, a guide drive mechanism 22, and a plurality of traction rollers 23. The guide roller 21 and the plurality of traction rollers 23 are rotatably disposed on the machine body 1. The gap 4 is located between the guide roller 21 and the coating head 31. The guide drive mechanism 22 is used to drive the guide roller 21 to rotate.

[0033] At least one pulling roller 23 is connected to a tension adjustment mechanism 24 .

[0034] That is, the guide roller 21 is used to ensure that the film material 5 passes through the gap 4, and the guide drive mechanism 22 is preferably a motor as a power source, and its purpose is to drive the guide roller 21 to rotate to apply a driving force to the film material 5; and the traction roller 23 guides the film material 5 to move, and under normal circumstances does not apply power to the film material 5. The traction roller 23 is provided with a tension adjustment mechanism 24, which controls the lifting and lowering of the traction roller 23 to change the pressure of the traction roller 23 on the film material 5, thereby achieving the effect of adjusting the tension of the film material 5.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention is disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical contents without departing from the scope of the technical solution of the present invention.
