Description

Technical Field

[0001] This utility model relates to the field of lining processing technology, specifically to a lining powder dotting machine. Background Technology

[0002] Interlining is a type of garment accessory, made from woven, knitted, or non-woven fabrics as the base material, processed through polymer treatment and machining. It is used in the inner layer of garments (such as collars, cuffs, and front panels), bonding with the outer fabric to provide reinforcement, stiffness, and shape retention; it is often referred to as the "skeleton" of clothing. Traditional interlinings are mainly made of cotton and linen, undergoing only simple sizing. With advancements in textile technology, modern interlinings have evolved into four main categories: woven resin black carbon interlining, woven resin interlining, woven (knitted) hot melt fused interlining, and non-woven hot melt fused interlining. An interlining powder dotting machine is an industrial device specifically designed for processing garment interlinings. Its core function is to achieve a strong bond between the outer fabric and the interlining by evenly spraying or printing hot melt adhesive powder dots onto the surface of the interlining.

[0003] This application improves upon existing technologies. In practical applications, existing fabric powder coating machines still have many technical limitations. During unwinding and transport, the surface of the fabric easily absorbs dust, fiber debris, and other impurities from the environment. If powder coating is applied directly without effective cleaning, the adhesive dots will not adhere firmly to the fabric surface, leading to problems such as delamination and uneven powder distribution, severely affecting product quality and increasing subsequent rework costs. Traditional powder coating machines typically lack integrated cleaning mechanisms, requiring manual pretreatment or additional cleaning equipment, which is not only cumbersome to operate but also makes it difficult to guarantee the stability of the cleaning effect.

A second motor 33 is fixedly connected to one of the connecting plates 30, and the output shaft of the second motor 33 is fixedly connected to the second gear 32. The model of the second motor 33 is BLDCM-42. The second motor 33 drives the second gear 32 to rotate, which in turn drives the cleaning roller 6 to rotate through the first gear 31 to clean the lining cloth.

[0033] Both the first and second gears are spur gears with a module of 2-3 and a gear ratio of 1:2 (20-30 teeth for the first gear and 40-60 teeth for the second gear). The output speed of the second motor is 100-200 r / min, and the final speed of the cleaning roller is 50-100 r / min.

[0034] In some examples, one of the movable blocks 25 has an installation groove 24, which is adapted to the cleaning roller 6. The inner wall of the end of the cleaning roller 6 that extends into the installation groove 24 is rotatably connected to a sealing connector 23. The outer wall of the end of the sealing connector 23 that extends out of the cleaning roller 6 is fixedly connected to a connecting block 22, which is fixedly connected to the inner wall of the installation groove 24. The dust absorbed in the cleaning roller 6 is transported through the sealing connector 23.

[0035] The rotating connection between the cleaning roller 6 and the sealing connector 23 is equipped with a skeleton oil seal (model TC30×45×10) to ensure that dust does not leak; the sealing connector 23 and the hose 10 are connected by threads (M20×1.5) and reinforced with hose clamps.

A fan 12 is fixedly connected to one side of the dust collection box 11, and dust is collected by the fan 12 and the dust collection box 11.

[0036] The fan is a centrifugal fan with a power of 500-800W. When working, the negative pressure value at the dust suction hole is 500-800Pa, ensuring that dust enters the cleaning roller through the dust suction hole.

[0037] In some examples, the first guide roller 5 is provided with an unwinding roller 3 on the side away from the cleaning roller 6. The unwinding roller 3 is rotatably connected to a vertical plate 2, and the vertical plate 2 is fixedly connected to the bottom plate 1. The unwinding roller 3 is used to unwind the lining.

[0038] In some examples, the fixed plate 4 has symmetrically distributed mounting plates 13 on the side away from the upright plate 2, and a storage box 14 is fixedly connected between the two mounting plates 13. The storage box 14 is fixedly connected to the powder dot frame 15. A second guide roller 16 is provided below the side of the powder dot frame 15 away from the movable guide roller 9, and the second guide roller 16 is rotatably connected to the mounting plate 13.

[0039] Working principle and usage process of this utility model: In this application, during use, the lining cloth is unloaded by the unwinding roller 3, which is guided by the first guide roller 5 to the space between the fixed guide roller 8 and the movable guide roller 9, and then reaches the top of the second guide roller 16. The powder dotting frame 15 sprays the lining cloth. When the lining cloth passes the cleaning roller 6, the output shaft of the second motor 33 rotates, driving the second gear 32 to rotate, which in turn drives the cleaning roller 6 to rotate through the first gear 31. The rotation of the cleaning roller 6 causes the cleaning brush bristles 27 to clean the surface of the lining cloth. The fan 12 absorbs dust through the hose 10, the sealing connector 23 and the dust suction hole 26, so that the dust enters the dust collection box 11 for collection, which facilitates the cleaning of the lining cloth, ensures the powder dotting quality and improves the powder dotting efficiency. In this application, when applying powder to linings of different thicknesses, the first motor 20 is started. The output shaft of the first motor 20 rotates, causing the stud 19 to rotate. The stud 19 causes the threaded sleeve 18 and the movable plate 17 to move, thereby adjusting the position of the cleaning roller 6 and the movable guide roller 9. The cleaning roller 6 moves under the guidance of the through groove 21 and the movable block 25, and the movable guide roller 9 moves under the guidance of the slide groove 28 and the slider 29, which facilitates the processing of linings of different thicknesses.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
