According to the coating device for waterproof sofa cloth production, the moving table moves up and down in a reciprocating mode to drive the connecting rod to rotate in a reciprocating mode, then the flapping rod is driven to make repeated contact with the surface of cloth to generate the flapping effect, and impurities can be bounced and separated from the surface of the cloth; and therefore, the condition that the effect is poor after coating due to the fact that impurities are attached to the surface of the cloth is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of sofa fabric production devices, and more specifically, to a coating device for producing waterproof sofa fabrics. Background Art

[0002] Sofas are one of the most common modern household items, and are widely loved by consumers for their softness and comfort. Sofas are generally composed of internal elastic pads and external sofa fabrics. In the field of sofa fabric production, waterproof coating is a key process used to give sofa fabrics waterproof functions and improve their durability and practicality. This requires the use of coating devices to apply waterproof coatings to the surface of sofa fabrics.

[0003] However, in the existing sofa fabric coating process, the sofa fabric transferred from the previous process is directly coated by a coating roller. On the one hand, impurities such as thread ends remaining from the previous production process will adhere to the surface of the sofa fabric. On the other hand, debris floating in the air will easily fall on the surface of the sofa fabric. The presence of these impurities will cause unevenness on the surface after coating, affecting the quality of the finished product. To this end, we provide a coating device for the production of waterproof sofa fabrics to solve the above problems. Utility Model Content

[0019] The utility model is described in detail below in conjunction with the accompanying drawings.

[0020] Reference Figure 1-Figure 2 A coating device for waterproof sofa fabric production includes a working box 1, first openings for fabric to enter and exit are provided on both sides of the working box 1, a partition 2 is vertically fixed in the working box 1, so that the interior of the working box 1 is divided into a dust removal chamber 3 for dust removal of the fabric and a processing chamber 4 for coating the fabric, a second opening for the fabric to pass through is provided on the partition 2, and a beating component and a dust suction component are provided in the dust removal chamber 3;

[0021] The beating assembly includes two supporting shafts 5 which are arranged in parallel and whose length direction is perpendicular to the conveying direction of the cloth. The two end portions of the two supporting shafts 5 are fixedly connected to the inner wall of the dust removal chamber 3, and the two supporting shafts 5 are symmetrically rotatably sleeved with connecting rods 6. A driving rod 7 is fixedly provided on the upper end of each connecting rod 6. A moving seat 8 is symmetrically slidably fitted in the dust removal chamber 3. The moving seat 8 is connected to a driving mechanism for driving it to reciprocate up and down, and each moving seat 8 is provided with a makeshift groove 9 for the corresponding two driving rods 7 to slide. A beating rod 10 is fixedly connected between the lower ends of the two connecting rods 6 located on the same supporting shaft 5.

[0022] The driving mechanism includes a motor, a turntable 11 is transmission-connected to the output shaft of the motor, a driving column 12 is fixedly provided on the turntable 11, a driving rod 13 is rotatably connected to the driving column 12, the other end of the driving rod 13 is rotatably connected to the top of the moving platform, a slider is fixedly provided on the inner wall of the dust removal chamber 3, the slider is in a T-shaped structure, and a slide groove 14 that slidably cooperates with the slider is provided on one side of the moving platform. When the motor drives the turntable 11 to rotate, the moving platform is subjected to the push-pull force of the driving column 12 through the driving rod 13 on the one hand, and on the other hand, the linear motion is limited by the cooperation of the slider and the slide groove 14, thereby realizing the up and down reciprocating motion of the moving platform.

[0023] The dust collection assembly includes a fan 15 fixedly installed on the top of the working box 1. The input end of the fan 15 is connected to a dust collection pipe 16 extending to the inside of the dust collection chamber 3. The dust collection pipe 16 is provided with a wind cover 17. The output end of the fan 15 is connected to a dust filter box 18. The fan 15 generates negative pressure adsorption when working, and impurities are sucked into the dust filter box 18 for filtration.

[0024] A coating assembly is provided in the processing chamber 4, and the coating assembly includes two coating rollers 19 rotatably connected in the processing chamber 4, and a gap is formed between the two coating rollers 19 for the cloth to pass through. A storage box 20 is fixedly provided on the top of the processing chamber 4, and a plurality of guide tubes 21 extending to the gap are connected to the bottom of the storage box 20.

[0025] The coating assembly also includes two baffles 22 symmetrically fixed in the processing chamber 4. The two baffles 22 are respectively located at both ends of the coating roller 19. When the waterproof coating is squeezed by the coating roller 19, the waterproof coating is prevented from being squeezed out from both sides, resulting in waste or accumulation in the processing chamber 4.

[0026] A rubber pad 23 is sleeved on the outer wall of the beating rod 10. The cushioning effect of the rubber pad 23 can effectively protect the surface of the cloth, reduce the impact force on the cloth, and avoid damaging the surface of the cloth.

[0027] Working principle: When the device is in use, the cloth first passes through the beating assembly, and the driving mechanism drives the moving seat 8 to slide up and down. Since the driving rod 7 on the connecting rod 6 is located in the giving way groove 9 of the moving platform, when the moving platform moves upward, it can drive the upper end of the connecting rod 6 connected to the moving seat 8 to rotate upward around the supporting shaft 5, and then the lower end of the connecting rod 6 drives the beating rod 10 to rotate downward and contact the cloth, and when the moving platform moves downward, it drives the upper end of the connecting rod 6 to rotate downward, and then the beating rod 10 rotates upward and breaks away from the contact with the cloth surface;

[0028] The movable platform reciprocates up and down, driving the connecting rod 6 to reciprocate around the supporting shaft 5, thereby driving the beating rod 10 to repeatedly contact the surface of the fabric to produce a beating effect. After beating, the impurities will bounce off the surface of the fabric and be sucked away by the dust collection component for removal. Subsequently, the waterproof coating is coated by the coating component, and the coating process is carried out in a relatively closed environment, thereby avoiding the occurrence of poor coating effect due to impurities attached to the surface of the fabric.

[0029] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
