Description

Technical Field

[0001] This utility model relates to the technical field of glass primer coating equipment, specifically a primer coating brushing tool. Background Technology

[0002] Glass primer is a step in the glass installation process aimed at improving surface wetting and adhesion, and in some cases, reducing surface roughness. During installation, a primer is applied to both the glass bonding surface and the surface of the substrate being bonded (automotive body panels, bus frames, steel structures). As the adhesive between the substrate and the glass, poor primer quality can lead to problems such as noise, leaks, and glass detachment. The quality of the primer application directly affects the reliability and stability of the bond. Currently, the following problems exist with brush-applied primer: (1) Air bubbles are easily generated when using primer bottles. During on-site operation, the primer is often poured into open containers, which is prone to volatilization, contamination, and solidification. The remaining primer liquid cannot be reused after use, which easily leads to waste and increases production costs. When using other tooling, if the brush head assembly needs to be replaced, the entire brush head assembly usually needs to be replaced, resulting in low reusability of the brush head assembly; (2) It is difficult to accurately control the amount of primer liquid dipped during the brushing process, which easily leads to uneven coating and the quality of the primer needs to be improved. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings in the aforementioned background technology by providing a primer brushing fixture to improve the reusability of the primer liquid and brush head assembly, and to improve the brushing quality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a primer brushing tool, including a bottle cap and a brush head assembly; The bottle cap includes a cap top and a cap body. The cap body is provided with a connecting end for connecting to the body of the base coating bottle. The cap top is provided with a feeding structure, and the feeding structure is provided with a feeding port. The brush head assembly includes a first connecting part, a second connecting part, and a brush head. The first connecting part is provided with a discharge structure, and the discharge structure is provided with a discharge port. The discharge structure is sleeved with the infeed structure and fixed by a threaded structure. The threaded structure can movably adjust the mating area of ​​the infeed port and the discharge port. The first connecting part is provided with a first clamping end, and the second connecting part is provided with a second clamping end. The left end of the first connecting part is movably connected to the right end of the second connecting part, and the right end of the first connecting part is clamped to the left end of the second connecting part by a clamping structure. The brush head is clamped between the first clamping end and the second clamping end. The discharge end of the discharge structure is in contact with the surface of the brush head.

[0005] The cap of the aforementioned primer brushing fixture is compatible with the threads of primer packaging bottles from different brands. During use, simply assemble the fixture to the primer bottle; there is no need to pour out the primer, avoiding secondary contamination and deactivation. After use, simply tighten the fixture to the primer bottle, meeting the requirements for reusability. When the brush head needs to be replaced, the first and second connecting parts can be easily loosened and then tightened again via a locking structure. All other components besides the brush head are reusable, thus improving the reusability of the primer liquid and brush head assembly. Furthermore, the fixture's threaded structure allows for adjustable contact area between the inlet and outlet, enabling control of the discharge rate and improving the accuracy of the primer coating thickness.

[0006] Furthermore, a retaining ring is fixedly provided on the side wall of the first or second connecting part, and a limiting rod is mounted on the retaining ring. Thus, the limiting rod can be used to accurately position the edge of the substrate, controlling quality. Simultaneously, the limiting rod is telescopic, meeting the brushing requirements of the middle area of ​​the substrate.

[0007] Furthermore, the feeding structure is a feeding pipe, the bottom end of which is provided with a first base plate and the top end of which is provided with a first opening; the bottom side wall of the feeding pipe is provided with the feeding port, and the top of the feeding pipe is provided with a first threaded structure for threaded connection with the discharging structure.

[0008] Furthermore, the inner surface of the feed tube includes a first threaded section and a first smooth circular section from top to bottom. This facilitates the design of the feed structure and the assembly and connection between the feed structure and the discharge structure.

[0009] Furthermore, the discharge structure is a discharge pipe, the bottom end of which is provided with a second base plate and the top end of which is provided with a second opening; the bottom side wall of the discharge pipe is provided with the discharge port, and the bottom of the discharge pipe is provided with a second threaded structure for threaded connection with the feeding structure.

[0010] Furthermore, the outer surface of the discharge pipe includes a second smooth circular segment, a second threaded segment, and a third smooth circular segment from top to bottom. This facilitates the design of the discharge structure and the assembly and connection between the discharge structure and the feeding structure.

[0011] Furthermore, the left end of the first connecting part and the right end of the second connecting part are movably connected by a hinge. This allows for easy separation of the first and second connecting parts, facilitating brush head replacement and installation.

[0012] Furthermore, the first clamping end / second clamping end is a serrated clamping plate. This ensures a tight fit between the first connecting part, the second connecting part and the brush head.

[0013] Furthermore, a sealing ring is provided between the bottle cap and the body of the primer bottle. This improves the sealing performance of the connection between the bottle cap and the primer bottle.

[0014] Furthermore, the brush head is a sponge brush head. This allows for convenient fixing and replacement of the brush head.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: (i) The bottle cap of this utility model can be adapted to the threads of the bottle body of different brands of primer packaging bottles. When using it, the tooling can be assembled and connected to the bottle body of the primer without pouring out the primer, thus avoiding secondary contamination and deactivation of the primer. After use, the tooling can be tightened to the primer bottle, which can meet the requirements of repeated use. When the brush head needs to be replaced, the first connecting part and the second connecting part can be loosened and put back into the tight state through the clamping structure, which can easily complete the replacement of the brush head. Except for the brush head, all other structures can be reused, thereby improving the reusability of primer liquid and brush head assembly.

[0016] (ii) The present invention can adjust the docking area of ​​the inlet and outlet through the threaded structure, and can control the discharge amount of the discharge pipe, thereby improving the accuracy of the base coat thickness.

[0017] (III) This utility model can achieve precise positioning of the substrate edge and control the quality through the limiting rod. At the same time, the limiting rod is telescopic to meet the brushing needs of the middle area of ​​the substrate. Attached Figure Description
