Embodiment Construction

[0016] like figure 1 Shown, a kind of electrostatic flocking device comprises feed roller 1, bristle roller 2, flocking chamber 3 and surplus velvet collection box 4, and described low pressure mechanism 5 comprises air suction port 51, dust box 52, filter 53 and Mechanical pump 54; the surface of the feed roller 1 is evenly provided with feeding grooves, and the fluff falls on the bristle roller 2 through the groove, and the bristle roller 2 is two rollers that are the same in size and rotate at the same speed in the opposite direction, so that the fluff can be Fully break up; the broken fluff enters the flocking chamber 3 after passing through the splitter plate 6, and the flocking chamber 3 is externally connected to a low-pressure device 5, and the low-pressure device 5 makes the flocking chamber 3 in a low vacuum state by means of pumping air .

[0017] The flocking chamber 3 includes a negative plate 31, a yarn delivery area 32 and a positive plate 33, the yarn delivery...

Abstract

According to the low-vacuum electrostatic flocking device. Flock falls into flock brushing rollers through grooves in the surface of a feeding roller and enters a flocking chamber after being fully scattered; the flocking chamber is externally connected with a low-pressure mechanism and is in a low-vacuum state; the low-pressure mechanism comprises an extraction opening, a dust collecting box, a filter and a mechanical pump; and a sensor is installed in the dust collecting box, monitors the amount of flock and dust in the dust collecting box in real time and transmits signals to control the opening and closing of the bottom plate of the dust collecting box. With the flocking device adopted, air resistance is reduced, the descending speed of the flock is increased, the flock and an adhesiveare combined more firmly, and a flocking effect is good.

Description

technical field [0001] The invention belongs to the field of textile equipment, in particular to an electrostatic flocking device. Background technique [0002] The existing flocking process is to use the physical characteristics of same-sex repulsion and opposite-sex attraction, so that the fluff is negatively charged, and the flocked body that needs to be flocked is placed at zero potential or grounded, and the fluff is affected by the different potential of the plant body. Attracted and vertically accelerated to fly to its surface, due to being coated with adhesive on the plant body, the fluff is vertically fixed on the surface of the plant body. Electrostatic flocking products are widely used in many fields such as textiles, automotive interiors, and decorations because of their good feel, wear resistance, simple process, and low cost. The current electrostatic flocking process is often as follows: when the fluff descends and touches the adhesive, the fluff is pierc...
