Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic flocking, in particular to a duckbill type adjustable high-voltage electrostatic flocking spray device. Background Art

[0002] Electrostatic flocking uses the physical property of like charges repelling and opposite charges attracting to give the fluff a negative charge. When the object to be flocked is placed under zero potential or grounding conditions, 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. Therefore, electrostatic flocking is a new production process that uses the natural properties of electric charge.

[0003] Prior art, such as the utility model patent CN221288557U, discloses a wind-powered, high-voltage, electrostatic rapid flocking machine. The machine comprises a housing, a wind-powered conveying mechanism, and a flocking mechanism. The flocking mechanism includes a flocking gun and a high-voltage generator. The flocking gun has a flocking channel within it, which is equipped with a high-voltage stylus. The high-voltage generator is connected to the stylus and forms a magnetic field within the flocking channel to constrain the flock. Using a vertical housing as the main body for the flock, the machine provides a handheld flocking device capable of large-scale, continuous, and continuous flocking.

[0004] However, the muzzle of the aforementioned prior art flocking gun is circular. This circular muzzle suffers from limited coverage and uneven hair distribution in actual use. In particular, the hair is concentrated in the middle of the muzzle, while the hair is sparser at the edges. This problem is particularly pronounced in high-precision flocking tasks involving large areas. The uneven hair distribution can directly affect the surface quality of the product, leading to visual defects and even compromising product functionality.

[0005] Based on this, it is necessary to study a duckbill type adjustable high-voltage electrostatic flocking equipment. Utility Model Content

[0006] In view of this, the purpose of the present invention is to provide a duckbill type adjustable high-voltage electrostatic flocking device, which can effectively solve the problems of small coverage and uneven flocking of the circular muzzle of the flocking gun of the existing flocking equipment.

[0007] In order to achieve the above purpose, the technical solution adopted by the present utility model is:

DETAILED DESCRIPTION

[0037] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:

[0038] This embodiment aims to provide a duckbill-type adjustable high-voltage electrostatic flocking device, which is mainly used for flocking operations. The circular muzzle 202 of the flocking gun 2 of the existing flocking equipment has the problems of small coverage and uneven flocking.

[0039] A duckbill type adjustable high voltage electrostatic flocking equipment, such as Figure 1 The present invention comprises a flocking box 1, a flocking gun 2, a flock feeding mechanism 3, and a control console 4. The control console 4 is provided on the flocking box 1. The flocking box 1 contains a down storage bin 101, which is trumpet-shaped and larger at the top and smaller at the bottom. A discharge port 102 is provided on the bin top, and a cover plate is hingedly provided at the discharge port 102. The cover plate is provided with a handle. A discharge port 103 is provided on the bottom 104 of the down storage bin 101.

[0040] like Figure 2 The flocking gun 2 includes a gun body 201, a gun muzzle 202 and a nozzle 203; Figure 3 A flocking channel 204 is provided in the gun body 201; an electrostatic generator 5 is provided in the flocking channel 204, and the electrostatic generator 5 forms a magnetic field inside the flocking channel 204 to constrain the flock; specifically, the electrostatic generator 5 includes a high-voltage contact pin 501 circumferentially arranged in the flocking channel 204, and the end of the high-voltage contact pin 501 has a pointed tip. There are multiple high-voltage contact pins 501, which are distributed in a circular array and fixed on the inner wall of the flocking channel 204 and extend along the flocking channel 204.

[0041] The circuit in the console 4 is connected to a high-voltage generator, which includes a transformer, a rectifier, a high-voltage generating module and a connector. The transformer is connected to the high-voltage generating module through the rectifier, and the high-voltage generating module is connected to the high-voltage contact pin 501; the transformer and the rectifier are arranged in the flocking box 1, and after rectification and voltage transformation, a 12V voltage is output to the high-voltage generating module. The high-voltage generating module and the high-voltage contact pin 501 are in the flocking gun 2, and the low voltage is converted into high voltage in the insulated flocking gun 2, which is safer to use.

[0042] The input end of the down feeding mechanism 3 is connected to the down storage bin 101, and the output end of the down feeding mechanism 3 is connected to the flocking channel 204; specifically, the down feeding mechanism 3 includes a feeding brush roller 301, a wind feeding pipe 302 and an air compressor 303; the feeding brush roller 301 is rotatably arranged in the down storage bin 101 through transmission components such as a rotating shaft and bearings, and the feeding brush roller 301 is connected to a motor 304 through transmission components such as a rotating shaft and a coupling.

[0043] One end of the wind feeding pipe 302 is connected to the flock storage bin 101 through the discharge port 103 , and the other end is connected to the flocking channel 204 . An air compressor 303 is provided on the wind feeding pipe 302 for providing wind power.

[0044] The motor 304 drives the unloading brush roller 301 to obtain the fluff from the fluff storage bin 101, and the fluff falls into the wind feeding pipe 302. The air compressor 303 provides wind power to transport the fluff to the flocking channel 204 of the flocking gun 2 through the wind feeding pipe 302; the high-voltage generator works to make the high-voltage contact needle 501 generate a magnetic field in the flocking channel 204; the wind power transports the fluff to the magnetic field control range, and the electrostatic flocking operation is performed.

[0045] like Figure 3 The muzzle 202 is connected to the flocking channel 204. The muzzle 202 is detachably provided with a nozzle 203. The nozzle 203 has a flat, duckbill-shaped structure. The down outlet of the nozzle 203 extends horizontally away from the muzzle 202, significantly expanding the spray area. This allows the down to be spread more effectively in the horizontal direction, allowing the flocking operation to cover a wider area at a time, thereby increasing flocking efficiency. The flat, duckbill-shaped nozzle 203 reduces the longitudinal span of the down outlet, alleviating the uneven flocking problem of existing circular nozzles 203, where down accumulates in the center and is sparse at the edges. This allows the down to be more evenly covered on the target surface, significantly improving the uniformity and overall quality of the flocking.

[0046] Further, such as Figure 3 A spherical clamp 2021 is fixed on the muzzle 202, and a spherical bayonet 2031 is provided at one end of the nozzle 203 close to the muzzle 202, which can semi-enclose the spherical clamp 2021. The spherical bayonet 2031 is made of injection molding materials such as polypropylene and ABS, and utilizes its own plastic deformation ability to make the nozzle 203 detachably sleeved on the spherical clamp 2021 through the spherical bayonet 2031, thereby forming a detachable ball hinge structure between the nozzle 203 and the muzzle 202, which can enable the nozzle 203 to be flexibly adjusted in angle and can maintain the angle through the friction between the spherical bayonet 2031 and the spherical clamp 2021. The operator can quickly adjust the direction and angle of the nozzle 203 to adapt to different working surface shapes to ensure uniform flocking.

[0047] Furthermore, considering that the down storage bin 101 is trumpet-shaped with a large top and a small bottom, it is inconvenient to operate when the down of different colors needs to be replaced. In this embodiment, the bin bottom 104 is detachably connected to the bottom of the down storage bin 101. Specifically, Figure 4 and Figure 5 One side of the bin bottom 104 is hingedly connected to the bottom of the down storage bin 101, and the other side is fixedly connected to a downwardly bent hook 6; a lock 7 is fixedly connected to the outer end surface of the down storage bin 101, and the lock 7 corresponds to the position of the hook 6 and can adapt to lock the bin bottom 104, such as Figure 6 The specific structure of the lock 7 and the hook 6 is the existing technology, and its principle will not be repeated here. It mainly serves to detachably connect the bottom 104 of the warehouse to the bottom of the down storage warehouse 101, so as to quickly open the bottom 104 to clean the down storage warehouse 101 and the down feeding mechanism 3 such as the unloading brush roller 301 and the wind feeding pipe 302, thereby improving the efficiency and quality of cleaning and replacing the down.

[0048] The control console 4 is connected to the flocking gun 2 through a wire motor 304 and an air compressor 303. The flocking gun 2 is provided with a flocking switch 205, which is controlled and connected to the high-voltage generator and the air compressor 303 through the control console 4. The flocking switch 205 can feedback a signal to the control console 4, so that the control console 4 controls the high-voltage generator and the air compressor 303, that is, the flocking switch 205 can simultaneously control the opening and closing of wind power transmission and electrostatic flocking.
