Description

Technical Field

[0001] This utility model relates to the field of powder spraying chamber cleaning technology, and in particular to an easy-to-clean electrostatic powder spraying chamber for cabinets. Background Technology

[0002] Powder coating is a process in which powder coating equipment sprays powder coating onto the surface of a workpiece. Under the action of electrostatics, the powder will be evenly adsorbed onto the surface of the workpiece to form a powder coating. The powder coating is then baked at high temperature to flow and cure, becoming a final coating with different effects. Powder coating operations are generally carried out in a powder spraying chamber. If there are many impurities in the powder spraying chamber, they can easily fall onto the workpiece, thus affecting the coating effect. Therefore, it is necessary to clean the powder spraying chamber regularly.

[0003] An existing patent (publication number: CN216727898U) discloses an easy-to-clean electrostatic powder coating chamber, including a powder coating chamber body. A ball screw is installed inside the powder coating chamber body, comprising a lead screw and a slide. A connecting rod is installed inside the powder coating chamber body, and a cleaning device is fixed on the connecting rod. The cleaning device includes a first air knife, a second air knife, and a cleaning seat. It blows paint powder from the bottom surface of the powder coating chamber body into the air through a back-blowing device and a dust recovery device, and then recovers it through the dust recovery device. However, this technical solution still has shortcomings, specifically as follows:

[0004] The current device blows paint powder into the air using a back-blowing mechanism. However, this paint powder tends to scatter during spraying, requiring the device to constantly move to completely clean it, making cleaning quite troublesome. Therefore, we propose an easy-to-clean electrostatic powder coating chamber for cabinets to solve the aforementioned problems. Utility Model Content

[0034] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0035] Example 1, refer to Figure 1-4 In this embodiment, to address the problem that existing devices blow paint powder into the air using a back-blowing device, causing the paint powder to easily scatter during spraying and requiring continuous movement of the device to completely clean it, making cleaning during spraying cumbersome, this utility model discloses an easy-to-clean electrostatic powder spraying chamber for cabinets.

[0036] The system includes a scraping mechanism 100, which includes a powder spraying chamber body 101. An organic body 102 is disposed inside the powder spraying chamber body 101. A wheel 102a is disposed at the bottom of the organic body 102. The wheel 102a is driven by a motor. The motor facilitates the rotation of the wheel 102a, thereby driving the organic body 102 to move within the powder spraying chamber body 101.

[0037] Two first electric push rods 103 are symmetrically arranged on the outer wall of the machine body 102. Scraper plates 104 are fixedly installed at the extended ends of the two first electric push rods 103. The upper ends of the two scraper plates 104 are connected by a telescopic scraper 105. The first electric push rods 103 push the scraper plates 104 to move and abut against the side wall of the powder spraying chamber body 101, and cause the telescopic scraper 105 to abut against the top wall of the powder spraying chamber body 101. Then the machine body 102 is started to move inside the powder spraying chamber body 101. As the machine body 102 moves, the inner wall of the powder spraying chamber body 101 is scraped by the cooperation of the scraper plates 104 and the telescopic scraper 105.

[0038] The adsorption mechanism 200 includes a telescopic adsorption plate 201, which is disposed at the bottom of the body 102. The body 102 has a dust storage chamber 202 inside. The telescopic adsorption plate 201 includes a first hollow plate 201a. Two second electric push rods 201b are symmetrically arranged on the outer wall of the first hollow plate 201a. The extended ends of the two second electric push rods 201b are fixedly provided with second hollow plates 201c. The outer walls of the second hollow plates 201c and the first hollow plate 201a are provided with a plurality of dust suction holes 201d. The first hollow plate 201a and the second hollow plate 201c are connected. The second electric push rods 201b can be used to push the second hollow plate 201c to move, thereby adjusting the length of the telescopic adsorption plate 201. The dust suction holes 201d can be used to suck the accumulated powder into the first hollow plate 201a and the second hollow plate 201c, and then into the dust storage chamber 202 for storage.

[0039] The dust storage chamber 202 is connected to the inner wall of the telescopic adsorption plate 201. A fan unit 203 is installed inside the dust storage chamber 202. A filter plate 202a is installed inside the dust storage chamber 202. The filter plate 202a is located between the fan unit 203 and the air inlet of the dust storage chamber 202. The filter plate 202a facilitates the filtration of accumulated dust drawn into the dust storage chamber 202, thereby reducing the possibility of accumulated dust entering the fan unit 203.

[0040] The specific working principle is as follows: First, the machine body 102 is placed inside the powder spraying chamber body 101. Then, the first electric push rod 103 pushes the scraper 104 to move and abut against the side wall of the powder spraying chamber body 101, and causes the telescopic scraper 105 to abut against the top wall of the powder spraying chamber body 101. Then, the machine body 102 is started to move inside the powder spraying chamber body 101. As the machine body 102 moves, the scraper 104 and the telescopic scraper 105 cooperate to scrape the inner wall of the powder spraying chamber body 101.

[0041] Meanwhile, the telescopic adsorption plate 201 scrapes the accumulated powder on the bottom wall of the powder spraying chamber body 101, and the fan unit 203 continuously sucks the accumulated powder into the dust storage chamber 202 through the telescopic adsorption plate 201. As the fan unit 203 operates, the airflow in the dust storage chamber 202 is sprayed onto the powder spraying chamber body 101 through the jet nozzle 204, thereby blowing the accumulated powder off the powder spraying chamber body 101. Therefore, it is more convenient to clean the accumulated powder on the powder spraying chamber body 101.

[0042] Example 2, refer to Figure 1-2 Based on the same concept as in Embodiment 1 above, this easy-to-clean cabinet electrostatic powder coating chamber further includes:

[0043] The side wall of the scraper 104 has a groove 104a, and a cleaning roller 104b is rotatably installed in the groove 104a. Rollers 104c are fixedly fitted at both ends of the cleaning roller 104b. The rollers 104c abut against the outer wall of the powder spraying chamber body 101. When the machine body 102 moves, it drives the scraper 104 to move synchronously. As the scraper 104 moves, it causes the rollers 104c to drive the cleaning roller 104b to rotate, thereby cleaning the accumulated powder on the powder spraying chamber body 101 through the cleaning roller 104b.

[0044] The telescopic scraper 105 includes two movable plates 105a. Each movable plate 105a has a limiting groove 105b on one side of its opposite side, and a limiting strip 105c is fixedly provided on one side of its opposite side. The limiting strip 105c slides with the inner wall of the limiting groove 105b. The cooperation between the limiting strip 105c and the limiting groove 105b facilitates the connection of the two movable plates 105a together and enables the two movable plates 105a to expand or contract, thereby enabling the telescopic scraper 105 to be used with powder spraying chamber bodies 101 of different widths.

[0045] The specific working principle is as follows: When the machine body 102 moves, it drives the scraper plate 104 to move synchronously. As the scraper plate 104 moves, it causes the roller 104c to drive the cleaning roller 104b to rotate, thereby cleaning the accumulated powder on the powder spraying chamber body 101 through the cleaning roller 104b.

[0046] The limiting strip 105c cooperates with the limiting groove 105b to facilitate the connection of the two movable plates 105a together, and to enable the two movable plates 105a to expand or contract, thereby enabling the telescopic scraper 105 to be used for scraping the powder spraying chamber body 101 of different widths.

[0047] Example 3, refer to Figure 3-4 In this embodiment, in order to solve the problem of poor cleaning effect when some existing cleaning devices clean the powder spraying chamber, based on the same concept as in Embodiment 1 above, the easy-to-clean cabinet electrostatic powder spraying chamber further includes:

[0048] The fan unit 203 includes a frame 203a and several fan bodies 203b. The frame 203a is fixedly installed in the dust storage chamber 202, and the several fan bodies 203b are equally spaced in the frame 203a. The frame 203a facilitates the installation of the several fan bodies 203b. The operation of the fan bodies 203b facilitates the suction of the dust accumulated on the outside of the telescopic adsorption plate 201 into the dust storage chamber 202 through the dust suction hole 201d. At the same time, the fan bodies 203b deliver the airflow to the jet nozzle 204.

[0049] The outer wall of the body 102 is provided with several jet nozzles 204. The air inlet end of the jet nozzles 204 is inserted into the body 102 and connected to the exhaust end of the fan unit 203. As the fan unit 203 operates, the airflow in the dust storage chamber 202 is sprayed onto the powder spraying chamber body 101 through the jet nozzles 204, thereby blowing down the accumulated powder on the powder spraying chamber body 101.

[0050] The air outlet of the nozzle 204 is bent toward the side wall and top wall of the powder spraying chamber body 101. The airflow is delivered to the nozzle 204 by the fan body 203b, and then the airflow is sprayed onto the powder spraying chamber body 101 through the nozzle 204, thereby blowing off the accumulated powder on the powder spraying chamber body 101.

[0051] The specific working principle is as follows: the frame 203a facilitates the installation of several fan bodies 203b. The operation of the fan bodies 203b facilitates the suction of the dust accumulated on the outside of the telescopic adsorption plate 201 into the dust storage chamber 202 through the dust suction hole 201d. At the same time, the fan bodies 203b deliver the airflow to the jet nozzle 204, and then the jet nozzle 204 sprays the airflow onto the powder spraying chamber body 101, thereby blowing off the accumulated powder on the powder spraying chamber body 101.

[0052] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
