Description

Technical Field

[0001] This utility model relates to the field of garment adhesive application technology, and in particular to a leak-proof high-speed adhesive application device. Background Technology

[0002] In the garment manufacturing industry, adhesives are widely used as an important auxiliary material in processes such as fabric bonding, lining fixation, and decorative component bonding. Traditional manual adhesive application methods are inefficient and produce poor uniformity, so the industry generally adopts spray adhesive equipment for automated operations. Spray adhesive equipment typically consists of an adhesive supply system, a pressure pump, a spray gun assembly, and a control system. A plunger pump or gear pump pressurizes and delivers the adhesive to the spray gun, where it is atomized by a needle (or nozzle) and evenly coated onto the fabric surface. This technology not only improves production efficiency but also allows for precise control of adhesive usage, reducing material waste, making it a key component of intelligent garment manufacturing.

[0003] However, in the workshop environment of a garment factory, due to the continuous operation of processes such as fabric cutting and sewing, a large amount of lint, fiber debris and dust particles are often suspended in the air. These pollutants are easy to adhere to the glue residue left during the glue spraying process. When uncured glue remains on the surface of the needle, lint and dust will gradually gather into clumps and block the needle outlet. At the same time, some fine particles may flow back into the needle with the glue, wear down the plunger and seals, or get embedded in the valve body gap under high pressure. The above phenomena not only lead to unstable glue spraying volume and distortion of coating pattern, but also cause glue leakage and glue breakage in severe cases, forcing the production line to stop frequently for cleaning, significantly reducing production efficiency and increasing maintenance costs.

[0004] Based on the above viewpoints, those skilled in the art have proposed a leak-proof high-speed dispensing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a leak-proof high-speed dispensing device. This leak-proof high-speed dispensing device introduces high-pressure air into the outer piston rod through a high-pressure air interface and an air inlet hose, thereby blowing out the lint and residual glue located at the bottom of the needle orifice. This ensures the quality of each dispensing and avoids problems such as lint entering the needle orifice, causing blockage and glue leakage.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A leak-proof high-speed dispensing device includes a dispensing head housing and a needle port located at the bottom of the dispensing head housing for dispensing adhesive. A piston sleeve is fixedly installed at the upper part of the interior of the dispensing head housing. An outer piston rod is slidably connected to the center of the piston sleeve, and a movable rod core is slidably connected and limited at the center of the outer piston rod. The outer piston rod and the movable rod core are located directly above the needle port. A top electromagnet is installed at the center of the upper inner wall of the dispensing head housing. A bottom iron core is installed on the top outer wall of the movable rod core. A spring is fixedly connected between the bottom iron core and the movable rod core. A high-pressure air inlet is provided at the bottom of the outer wall of the dispensing head housing, and a flexible air hose connects the high-pressure air inlet to the outer piston rod. Preferably, a limiting sleeve is fixedly connected to the outer wall of the outer piston rod and the upper part of the piston sleeve. Two sets of injection ports are provided on the outer wall of the dispensing head housing, located on the upper and lower sides of the top wall of the limiting sleeve, respectively.

[0008] Preferably, a glue injection tube is installed on the lower part of the outer side wall of the glue head shell, and a glue injection connector is provided at the top of the glue injection tube.

[0009] Preferably, the bottom of the rubber head housing is provided with a dustproof component, the dustproof component includes a dustproof sleeve, the dustproof sleeve is composed of front and rear parts, and the two parts of the dustproof sleeve can slide relative to each other.

[0010] Preferably, the dust cover is positioned on the outside of the needle tip.

[0011] Preferably, a bottom electromagnet is provided at the center of the rear inner wall of the dust cover, a plurality of return springs are provided on the rear inner wall of the dust cover, an iron frame is fixedly connected to the front inner wall of the dust cover, the other ends of the plurality of return springs are fixedly connected to the iron frame, a guide tube is provided at the center of the iron frame, and the guide tube is located below the needle port.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, high-pressure air is introduced into the outer piston rod through a high-pressure air interface and an air duct, thereby blowing out the lint and residual glue located at the bottom of the needle orifice. This ensures the quality of glue dispensing each time and avoids problems such as lint entering the needle orifice and causing blockage or glue leakage.

[0014] In this invention, when the top electromagnet is energized, the bottom electromagnet is also energized. At this time, the iron frame is attracted by the bottom electromagnet, causing the front half of the dust cover and the guide tube to move backward together. When the high-pressure air is blown out from the outer piston rod, the residual glue and lint will be discharged and collected through the guide tube, thus preventing the residual glue and lint from falling on the clothing.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Refer to Figure 1-4This utility model provides an embodiment of a leak-proof high-speed dispensing device, including a dispensing head housing 1 and a needle port located at the bottom of the dispensing head housing 1 for dispensing glue. A piston sleeve 7 is fixedly installed at the upper part of the inside of the dispensing head housing 1. An outer piston rod 8 is slidably connected to the center of the piston sleeve 7, and a movable rod core 9 is slidably connected to the center of the outer piston rod 8. The outer piston rod 8 and the movable rod core 9 are located directly above the needle port. A top electromagnet 11 is installed at the center of the upper inner wall of the dispensing head housing 1. A bottom iron core 10 is installed on the top outer side wall of the movable rod core 9. A spring is fixedly connected between the bottom iron core 10 and the movable rod core 9. A high-pressure air interface 6 is provided at the bottom of the outer side wall of the dispensing head housing 1. An air duct 13 is connected between the high-pressure air interface 6 and the outer piston rod 8. The device uses a separate design for the top glue rod to prevent lint from entering the needle orifice. After each glue application, the top electromagnet 11 is energized, causing the bottom iron core 10 to move the movable rod core 9 upwards, opening the bottom of the outer piston rod 8. High-pressure air enters the outer piston rod 8 through the high-pressure air interface 6 and the air duct 13, blowing out the lint and residual glue at the bottom of the needle orifice. This ensures the quality of each glue application and prevents lint from entering the needle orifice, causing blockage and glue leakage.

[0024] A limiting sleeve 12 is fixedly connected to the outer wall of the outer piston rod 8 and the upper part of the piston sleeve 7. Two sets of liquid injection ports 4 are provided on the outer wall of the rubber head shell 1, located on the upper and lower sides of the top wall of the limiting sleeve 12 respectively. The two sets of liquid injection ports 4 alternately draw liquid, thereby adjusting the sliding motion of the movable rod core 9 and the outer piston rod 8. When liquid is injected into the top liquid injection port 4 and liquid is drawn out by the bottom liquid injection port 4, the liquid squeezes the limiting sleeve 12 downward, thereby causing the outer piston rod 8 and the movable rod core 9 to move downward. At the same time, when liquid is injected into the bottom liquid injection port 4 and liquid is drawn out by the top liquid injection port 4, the limiting sleeve 12 will drive the outer piston rod 8 and the movable rod core 9 to move upward together. A glue injection tube 2 is installed on the lower part of the outer wall of the rubber head shell 1, and a glue injection connector 3 is provided on the top of the glue injection tube 2. The adhesive is injected into the head housing 1 through the adhesive injection connector 3. The adhesive enters the head housing 1 through the adhesive injection tube 2, and then the adhesive is pushed out by the outer piston rod 8 and the movable rod core 9.

[0025] The bottom of the nozzle housing 1 is provided with a dustproof component 5, which includes a dustproof sleeve 51. The dustproof sleeve 51 consists of two parts, front and back, which can slide relative to each other. The dustproof sleeve 51 is located outside the needle opening. The dustproof sleeve 51 forms a barrier to prevent lint in the air from entering the needle opening. A bottom electromagnet 52 is provided at the center of the rear inner wall of the dustproof sleeve 51. Several return springs 53 are provided on the rear inner wall of the dustproof sleeve 51. An iron frame 54 is fixedly connected to the front inner wall of the dustproof sleeve 51. The other ends of the return springs 53 are fixedly connected to the iron frame 54. A guide tube 55 is provided at the center of the iron frame 54 and is located below the needle opening. When the top electromagnet 11 is energized, the bottom electromagnet 52 is also energized. At this time, the iron frame 54 is attracted by the bottom electromagnet 52, which drives the front half of the dust cover 51 and the guide tube 55 to move backward together. When the high-pressure air is blown out from the outer piston rod 8, the residual glue and lint will be discharged and collected through the guide tube 55, thus preventing the residual glue and lint from falling on the clothing.

[0026] Working principle: Glue is injected into the glue head housing 1 through the glue injection connector 3. The glue enters the interior of the glue head housing 1 through the glue injection tube 2. The device uses a separate design of the top glue rod to prevent lint from entering the needle orifice. After each glue injection, the top electromagnet 11 is energized. At this time, the bottom iron core 10 drives the movable rod core 9 to move upward, causing the bottom of the outer piston rod 8 to open. High-pressure air enters the outer piston rod 8 through the high-pressure air interface 6 and the air duct 13, thereby opening the bottom of the needle orifice. The lint and residual glue are blown out, ensuring the quality of each glue dispensing and preventing lint from entering the needle orifice, causing blockage and glue leakage. When the top electromagnet 11 is energized, the bottom electromagnet 52 is also energized. At this time, the iron frame 54 is attracted by the bottom electromagnet 52, causing the front half of the dust cover 51 and the guide tube 55 to move backward together. When the high-pressure air is blown out from the outer piston rod 8, the residual glue and lint will be discharged and collected through the guide tube 55, preventing residual glue and lint from falling on the clothing.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
