Abstract
Description
Technical Field
[0001] This utility model belongs to the field of parts spraying technology, and in particular relates to a parts spraying device that prevents clogging. Background Technology
[0002] Traditional parts painting processes face several key challenges, including nozzle clogging, low painting efficiency, material waste, and inconsistent coating quality. These problems typically stem from impurities in the coating material, incomplete material flow during painting, and improper handling of temperature-sensitive materials. Nozzle clogging is particularly prevalent, leading to painting interruptions, frequent maintenance, and in severe cases, damage to nozzle components, increasing maintenance costs and production downtime. Furthermore, foreign matter in unfiltered coating materials directly impacts coating quality, causing surface defects and affecting the product's appearance and performance.
[0003] Traditional cleaning methods are inefficient, often requiring manual disassembly of the spray nozzle for cleaning, which is time-consuming and labor-intensive, and cannot achieve immediate cleaning, leading to the drying of residual material and further exacerbating clogging problems. Furthermore, for temperature-sensitive spray materials, such as certain high-viscosity coatings, without proper heating, the material may become too viscous or even solidify at low temperatures, affecting normal spraying and causing uneven spraying, dripping, or intermittent spraying, thus impacting production efficiency and product quality.
[0004] Based on the above problems, this utility model proposes an anti-clogging parts spraying device, which aims to achieve the anti-clogging function of the spraying device through innovative design, thereby improving the continuity, efficiency and quality of the spraying operation.

By integrating a nozzle controlled by a valve body, a matching cleaning switch, a filter cartridge for nozzle feeding, and a hot melt assembly to assist the smooth operation of the nozzle, it solves the problems of nozzle clogging, material purity, and temperature control in existing parts spraying devices.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to a clog-resistant parts spraying device, comprising a spray head for parts spraying, a feeding assembly for supplying material to the spray head, and a heat-melting assembly fitted over the spray head; the spray head includes a valve body, a feed pipe disposed on the upper part of the valve body, a spraying pipe disposed on the lower side of the valve body, a spray nozzle fixed to the bottom of the spraying pipe, and a cleaning pipe disposed on the side of the valve body; the feeding assembly includes a hopper, a processing chamber integrally disposed on the upper part of the hopper, a feeding pipe disposed on the side of the processing chamber, and a filter cartridge disposed inside the processing chamber; the heat-melting assembly includes a heat-insulating sleeve fitted over the spraying pipe, heating pipes evenly distributed inside the heat-insulating sleeve, and a controller connected to the heating pipes.

The spraying and cleaning processes are controlled by the valve body 201, achieving precise control and timely cleaning of the spraying liquid. The feed pipe 206 connected above the valve body 201 ensures continuous material supply, while the spraying pipe 207 and spraying head 205 below are responsible for the actual spraying operation. The introduction of the cleaning pipe 204 allows for activation by an electromagnetic switch 203 during work breaks or when necessary, delivering cleaning liquid from an external cleaning tank to the inside of the spray head 2, effectively removing residual materials and preventing clogging.
[0031] Specifically, the valve body 201 has an ear seat 202 integrally provided on its side, and the ear seat 202 is fixed to the external support by fasteners. The valve body 201 has an electromagnetic switch 203 provided on its side, and the electromagnetic switch 203 is used to control the internal valve stem of the valve body 201.
[0032] Furthermore, the cleaning pipe 204 is connected to an external cleaning tank via a hose, and the cleaning pipe 204 delivers cleaning fluid to the valve body 201.
[0033] The operation process of this embodiment is as follows: turn on the power of the equipment, activate the valve stem in the valve body 201 through the electromagnetic switch 203 to allow the material to flow through the feed pipe 206 to the spray pipe 207, observe the material output of the spray head 205, adjust the spraying parameters (such as flow rate, pressure, etc.) to achieve the ideal spraying effect, align the spray head 2 with the part to be sprayed, maintain an appropriate distance and angle, and start uniform spraying. Adjust the spraying parameters or equipment position as needed. After the spraying operation is completed, turn off the electromagnetic switch 203 to stop the supply of spraying material, start the cleaning program, and input cleaning fluid into the inside of the spray head 2 through the cleaning pipe 204 to flush the spray head 2 and the pipeline to prevent residual material from drying and clogging. After cleaning is completed, turn off the supply of cleaning fluid and drain the residual liquid in the pipeline.
[0034] Example 2

The filter cartridge 105 is disposed inside to filter impurities and large particles. The filter cartridge 105 is checked and replaced regularly to maintain the quality of the spraying material, aiming to reduce impurities entering the spray head 2 and prevent clogging.
[0036] Specifically, an end cap 103 is fixed to the top of the filter cartridge 105, and the end cap 103 is threadedly fitted to the top opening of the treatment chamber 101.
