[0002] As a kind of cloth with excellent waterproof performance and good elasticity, waterproof elastic cloth is widely used in fields such as outdoor clothing, medical supplies, and industrial products. This is because a waterproof coating material is coated on the surface of the elastic cloth. The coating device includes two coating rollers, and the elastic cloth drenched with the coating passes through the gap between the two coating rollers, and the coating is evenly spread on the surface of the cloth to form a coating with a uniform thickness.

However, the existing coating rollers are more troublesome to adjust, and it is difficult to accurately control the distance between the coating rollers. If not controlled properly, it is easy to squeeze and damage the elastic cloth or make the coated coating too thick, and it needs to be adjusted to the expected distance after multiple debuggings, resulting in the problem of reduced processing efficiency.

[0019] The following will describe the present utility model in detail with reference to the drawings.

[0020] Refer to Figure 1 - Figure 2 , a coating device for the production of waterproof elastic cloth, including a base 1. Fixed plates 2 are symmetrically fixed on both sides of the base 1. A first fixing frame 3 and a second fixing frame 4 are rotatably matched up and down between the two fixed plates 2. One ends of the first fixing frame 3 and the second fixing frame 4 away from the fixed plates 2 are respectively rotatably connected with a first coating roller 5 and a second coating roller 6. A coating gap for the cloth to pass through is formed between the first coating roller 5 and the second coating roller 6. Positioning plates 7 are symmetrically fixed on both sides of the base 1. A bidirectional threaded rod 8 is rotatably connected to the positioning plates 7. Movable blocks 9 are symmetrically sleeved on the bidirectional threaded rod 8 by threads. Slide columns 10 are slidably connected to both movable blocks 9. The two slide columns 10 are respectively fixedly connected to the first fixing frame 3 and the second fixing frame 4. A feeding component for improving the supply of the coating material is arranged at the coating gap.

[0021] A limiting rod 11 is fixedly arranged on one side of the first fixing frame 3 facing the second fixing frame 4. When the limiting rod 11 abuts against the second fixing frame 4, the first coating roller 5 and the second coating roller 6 reach the minimum coating gap, thereby controlling the maximum rotation amplitude of the bidirectional threaded rod 8 and avoiding the collision between the first coating roller 5 and the second coating roller 6.

[0022] A chute 12 is horizontally opened in the movable block 9. One side of the chute 12 facing the slide column 10 extends to the outside of the movable block 9 for the slide column 10 to extend into. When the first fixing frame 3 and the second fixing frame 4 rotate, the horizontal position of the slide column 10 will be driven to change, and the chute 12 can provide space for the movement of the slide column 10. The inner walls at both ends of the chute 12 will limit the slide column 10 to prevent the slide column 10 from separating from the chute 12.

[0023] A reference rod 13 parallel to the bidirectional threaded rod 8 is fixedly arranged on the positioning plate 7. Scale lines 14 are arranged on the reference rod 13. The reference rod 13 and the scale lines 14 thereon provide an intuitive visual reference for the user, enabling the user to more easily and accurately judge the position of the movable block 9, and allowing for more rapid positioning and adjustment, thereby saving time and improving work efficiency.

[0024] A rotating wheel handle 15 is fixedly arranged at the upper end of the bidirectional threaded rod 8. The provided rotating wheel handle 15 facilitates the user to operate and rotate the bidirectional threaded rod 8.

[0025] The feeding assembly includes a bottom plate 16 fixed relative to the second fixing frame 4. The bottom plate 16 extends along the width direction of the base 1 and has a feeding gap for the cloth to pass through between the bottom plate 16 and the second coating roller 6. Stopping plates 17 are symmetrically arranged at both ends of the bottom plate 16. One side of the stopping plate 17 is in contact with the second coating roller 6. The distance between the two stopping plates 17 is adjustable. The adjustment structure can be realized by using conventional technical means. For example, the stopping plate 17 can be set as a U-shaped structure, which is clamped on the bottom plate 16 for sliding, and then the stopping plate 17 is pressed against the bottom plate 16 by a screw passing through itself.

[0026] Working principle: When the device is in use, when it is necessary to adjust the distance between the first coating roller 5 and the second coating roller 6, the bidirectional threaded rod 8 is rotated. The two movable blocks 9 move in the direction of approaching each other under the action of the thread. During the moving process, a vertical acting force will be applied to the sliding column 10 that is slidably matched with it. Then, the first fixing frame 3 and the second fixing frame 4 are driven to rotate relatively around the fixing plate 2, and the first coating roller 5 and the second coating roller 6 synchronously deflect in the direction of approaching each other, that is, the gap between the first coating roller 5 and the second coating roller 6 is reduced. Similarly, rotating the bidirectional threaded rod 8 in the reverse direction can expand the gap between the first coating roller 5 and the second coating roller 6, realizing the rapid adjustment of the distance between the first coating roller 5 and the second coating roller 6 and ensuring the coating effect of the elastic cloth.

[0027] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
