Description

Technical Field

[0001] The utility model relates to the technical field of flocking, in particular to a flocking device for jacquard fabrics. Background Art

[0002] When weaving jacquard fabrics, the warp and weft structures are changed to form patterns. The yarn count is fine and the requirements for raw cotton are extremely high. It can be divided into shuttle weaving, warp knitting jacquard and weft knitting jacquard. Weft knitting fabrics have good elasticity when pulled horizontally and vertically, while warp knitting and shuttle weaving jacquards are inelastic when pulled horizontally and vertically. Flocking is to fix the fibers vertically on a substrate coated with an adhesive. The principle of flocking is to use the physical property of opposite charges attracting each other, set positive charges on the substrate and negative charges on the fluff. The fluff is attracted by the positive charges on the substrate and will stick vertically to the surface of the substrate. Under the action of the adhesive, it is fixed on the substrate.

[0003] The traditional flocking device has poor dust removal function, and the dust on the surface of the substrate cannot be removed. The adhesive cannot cover the substrate well, which will affect the flocking effect and cause the fluff to fall off later, affecting the performance of the product. The practical performance needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a jacquard fabric flocking device to solve the problem that the traditional flocking device proposed in the above background technology has poor dust removal function, the dust stuck on the surface of the substrate cannot be removed, and the adhesive cannot be well covered on the substrate, which will affect the flocking effect and cause the fluff to fall off in the later stage, affecting the performance of the product, and the practical performance needs to be improved.

[0006] Preferably, the cavity roller is a double-section structure.

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] Through the cooperation among the bottom plate, shell, jacquard fabric, electrostatic roller, velvet spreading assembly, feed roller and dust removal mechanism, the operator first places the jacquard fabric to be flocked horizontally on the front side of the shell, and the driving device on the rear side of the shell makes the feed roller, cavity roller and electrostatic roller rotate at a uniform speed. During the transmission of the jacquard fabric, the electrostatic roller transfers the positive charge to the top of the jacquard fabric, and starts the velvet spreading assembly to discharge the negatively charged fibers, so that the fibers are vertically adsorbed to the surface of the jacquard fabric to complete the flocking operation. During the rotation of the cavity roller, the first brush can clean and remove dust from the jacquard fabric. In conjunction with the negative pressure space formed inside the cavity roller during the operation of the suction fan, the dust swept by the first brush can be sucked in through the dust suction hole and discharged into the filter bag for storage.

The second brush contacts and cleans the inner wall of the filter bag, which greatly reduces the probability of local blockage of the inner wall of the filter bag, increases the dust storage capacity of the filter bag, increases the operating time of the device, and reduces the frequency of cleaning and maintenance.
