Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, in particular to an electrostatic flocking device. Background Art

[0002] Electrostatic flocking uses the physical property that like charges repel and opposite charges attract, so that the fluff carries a negative charge. When the object to be flocked is placed at zero potential or grounded, the fluff is attracted by the object with different potential and accelerates vertically to the surface of the object to be flocked. Since the object is coated with adhesive, the fluff is vertically adhered to the object. Traditional electrostatic flocking equipment directly sprinkles the fluff from the upper side, which easily leads to unstable adhesion between the fluff and the glue on the base fabric layer, insufficient implantation depth of the fluff, and easy falling of the fluff, resulting in poor flocking effect and affecting the quality of the fluff cloth.

[0003] Chinese invention patent with publication number CN110449323A discloses a fabric flocking process and a flocking device thereof, which accelerates the fluff multiple times through an accelerating tube, so that the fluff has a faster speed and is inserted deeper into the glue, but it is easy to have uneven distribution of the fluff and the fluff is knotted into clumps.

[0014] Beneficial effects of the present invention: The present invention provides a first electric grid at the outlet of the first pipe and a second electric grid in the flocking box. When the fluff passes through the first electric grid, it will be initially charged by the electric field and obtain a certain electrostatic adsorption force; after entering the flocking box, it will be further acted upon by the second electric grid. The synergistic effect of the two electric fields effectively improves the adsorption effect of the fluff, and makes the fluff distribution on the surface of the flocked object more uniform. During the rotation process, the impeller can not only accelerate the transmission of the fluff, but also have a certain dispersion effect on the fluff, preventing the fluff from clumping or piling up during the transmission process. In this way, when the fluff passes through the first electric grid and the second electric grid, each strand of fluff can better contact the electric field, thereby obtaining more uniform electrostatic adsorption, further improving the flocking effect.

DETAILED DESCRIPTION

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0018] Example: Figure 1-8 As shown, an electrostatic flocking device includes a material box 1, a flocking box 2 and an acceleration box 3. The flocking box 2 is located below the material box 1, and the acceleration box 3 is located between the material box 1 and the flocking box 2.

[0019] The acceleration box 3 has a circular acceleration chamber 301 in it. An impeller 302 is arranged in the acceleration chamber 301. The impeller 302 is driven to rotate by a first motor 303 on one side of the axial direction.

[0020] The acceleration chamber 301 is connected to a first pipe 4 and a second pipe 5 respectively, the other end of the first pipe 4 is connected to the material box 1, and a first power grid 6 is provided at the outlet of the first pipe 4; the other end of the second pipe 5 is connected to the flocking box 2, and a second power grid 8 is provided in the flocking box 2. The first pipe 4 and the second pipe 5 are both connected to the acceleration chamber 301. The first power grid 6 and the second power grid 8 are both connected to an electrostatic generator.

[0021] The outlet end of the first pipe 4 is located at one side of the acceleration chamber 301 in the axial direction and is arranged opposite to the first motor 303 . The inlet end of the second pipe 5 is located at one side of the acceleration chamber 301 in the circumferential direction.

[0022] like Figure 8 As shown, a stirring mechanism 7 is arranged in the material box 1 , the stirring mechanism 7 is arranged at the bottom of the material box 1 , and the inlet of the first pipeline 4 is arranged at the upper end of the material box 1 .

[0023] The stirring mechanism 7 includes a vertically arranged stirring shaft 701, a second motor 704 connected to the lower end of the stirring shaft 701, and a stirring rod 702 arranged on the stirring shaft 701. The stirring shaft 701 is also provided with a fan blade 703, which is arranged below the stirring rod 702. The fan blade 703 generates an upward airflow by rotating, and the scattered fluff is blown upward and sucked into the acceleration chamber 301 through the first pipe 4.

[0024] like Figure 4 and Figure 5 As shown, the impeller 302 includes a rotating shaft 3021, blades 3022 distributed in a circle on the outside of the rotating shaft 3021, and a connecting rod 3023 connected between the blades 3022 and the rotating shaft 3021. The two ends of the blades 3022 are respectively connected to the rotating shaft 3021 through the connecting rod 3023, and the blades 3022 and the rotating shaft 3021 form a gap in the radial direction for the fluff to pass through.

[0025] When the impeller 302 rotates counterclockwise, the air in the acceleration chamber 301 is discharged through the second pipe 5, thereby forming a negative pressure, and the fluff is sucked from the material box 1 through the first pipe 4. After the fluff enters the acceleration chamber 301, it is negatively charged by the first electric grid 6, and the fluff rotates in the acceleration chamber 301 as the impeller 302 rotates. Under the action of centrifugal force and repulsive force of the same charge, the fluff is broken up and evenly distributed in the acceleration chamber 301; when the opening of the second pipe 5 is opened, the fluff is gradually thrown into the second pipe 5 at a certain speed.

[0026] like Figure 4 and Figure 6 As shown, a control panel 304 is provided at the inlet end of the second pipe 5. The control panel 304 is an arc panel concentric with the acceleration chamber 301. A sliding groove 305 is provided in the wall of the acceleration box 3. The control panel 304 is slidably installed in the sliding groove 305. A control mechanism for driving the control panel 304 to move is provided on the outside of the acceleration box 3. The control mechanism controls the movement of the control panel 304 to open or close the inlet of the second pipe 5.

[0027] The control mechanism includes a third motor 308, a gear 307 disposed on the motor output shaft, and an arc rack 306 disposed on the control board 304, wherein the gear 307 meshes with the arc rack 306. The third motor 308 is fixedly mounted outside the acceleration box 3, and the arc rack 306 is fixed on the control board 304.

[0028] like Figure 7 As shown, a ventilation portion 3041 , a closing portion 3042 and a discharge portion 3043 are sequentially arranged on the control plate 304 along the circumferential direction. A mesh 3044 is arranged at the ventilation portion 3041 , and a discharge through hole 3045 is arranged at the discharge portion 3043 .

[0029] When the control board 304 is moving, when the ventilation part 3041 is located at the inlet end of the second pipe 5, the air in the acceleration chamber 301 is discharged through the second pipe 5, thereby forming a negative pressure, and the fluff is sucked from the material box 1 through the first pipe 4, so that the fluff enters the acceleration chamber 301; when the amount of fluff is sufficient, the control board 304 moves clockwise, so that the closing part 3042 is located at the inlet end of the second pipe 5, at this time the inlet of the second pipe 5 is closed, and the fluff rotates with the impeller 302, so that the fluff is redistributed in the acceleration chamber 301 and obtains a certain speed; then the control board 304 moves clockwise, so that the discharge part 3043 is located at the inlet end of the second pipe 5, at this time the acceleration chamber 301 is connected with the second pipe 5 through the discharge through hole 3045, and the fast-moving fluff enters the flocking box 2 through the second pipe 5, and is re-charged with negative charge through the second electric grid in the flocking box 2, so that the fluff can be flocked better.
