Description

Technical Field

[0001] This utility model relates to the field of powder application technology, specifically to a novel powder application structure. Background Technology

[0002] In fields involving powder handling, such as food processing, printing and dyeing, and chemical production, powder box components are key parts to ensure the normal operation of equipment. Their main function is to store powder and evenly transport it to subsequent processes through structures such as brushes.

[0003] Traditional powder box assemblies are also unsatisfactory in terms of powder handling performance. The powder box lacks an effective agitation mechanism, causing powder to easily clump during storage and transport due to static conditions. This clumped powder not only clogs the screen but also results in uneven powder distribution by the brushes. Furthermore, over time, the brush bristles easily accumulate clumped powder, and the lack of a dedicated cleaning mechanism further exacerbates this problem. This accumulated powder leads to uneven powder coarseness in subsequent brush dispensing, severely impacting product processing quality. Disassembly and cleaning of traditional powder box assemblies are extremely inconvenient, requiring multiple tools and involving cumbersome steps, consuming significant time and manpower. Therefore, a novel powder dispensing structure is proposed. Utility Model Content

[0004] The main objective of this invention is to provide a novel powder-spraying structure that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A novel powder dispensing structure includes a motor housing and a powder box assembly. One end of the motor housing is provided with a powder box mounting base, and one end of the powder box assembly is provided with a powder box mounting plate. The powder box assembly is mounted on one side of the powder box mounting base via the powder box mounting plate.

[0007] A brush shaft is rotatably mounted inside the powder box assembly. One end of the brush shaft is fixedly connected to the motor output end inside the motor box, and the other end of the brush shaft is fitted with a bearing seat inside the powder box. The bearing seat inside the powder box is installed on the inner side of the powder box assembly. The shaft end of the brush shaft is eccentric and fitted with a linkage component. One end of the linkage component is fixedly connected to one side of the powder mixing component. The powder mixing component is installed inclined downward inside the powder box assembly.

[0008] Specifically, a brush is provided on the outer side of the brush shaft, and a powder scraping stud is horizontally installed inside the powder box assembly.

[0009] Specifically, powder mixing guide blocks are fixedly installed on both inner sides of the powder box assembly, and the powder mixing assembly is movably installed inside the two powder mixing guide blocks.

[0010] Specifically, the bottom of the powder box assembly is provided with a screen, the end of the powder box assembly away from the motor box is equipped with a powder box side baffle, and one side of the powder box side baffle is equipped with a powder box outer bearing seat.

[0011] Specifically, a scraper weldment is provided on the lower side of one side of the powder box assembly.

[0012] Specifically, a motor speed controller is provided on one side of the motor housing.

[0013] The beneficial effects of this utility model are:

[0014] (1) The novel powder-spreading structure described in this utility model has an internal brush shaft that rotates, causing the scraping screw to bounce the brush and dislodge the clumped powder. The powder mixing component reduces powder clumping, and in conjunction with the screen, ensures that the powder is spread finely and evenly. The brush structure is reasonably designed and can maintain a good powder-spreading effect for a long time.

[0015] (2) The novel powder-spreading structure described in this utility model has a powder box assembly connected to a mounting base via a mounting plate. It can be disassembled by rotating the outer bearing seat, which is convenient for cleaning.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As one embodiment of this utility model, such as Figures 1-5 As shown, the present invention provides a novel powder-spreading structure, including a motor housing 1 and a powder box assembly 4. One end of the motor housing 1 is provided with a powder box mounting base 3, and one end of the powder box assembly 4 is provided with a powder box mounting plate 14. The powder box assembly 4 is mounted on one side of the powder box mounting base 3 via the powder box mounting plate 14.

[0025] A brush shaft 8 is rotatably mounted inside the powder box assembly 4. One end of the brush shaft 8 is fixedly connected to the motor output end inside the motor housing 1. The other end of the brush shaft 8 is fitted with a powder box bearing seat 15. The powder box bearing seat 15 is installed on the inner side of the powder box assembly 4. The shaft end of the brush shaft 8 is eccentric and fitted with a linkage component 10. One end of the linkage component 10 is fixedly connected to one side of the powder mixing component 6. The powder mixing component 6 is installed inclined downward inside the powder box assembly 4.

[0026] The present invention also includes a brush 9 provided on the outer side of the brush shaft 8, and a powder scraping stud 16 horizontally installed inside the powder box assembly 4.

[0027] The present invention also includes that powder box assembly 4 has powder stirring guide blocks 5 fixedly installed on both sides of the powder box assembly 4, and the powder stirring assembly 6 is movably installed inside the two powder stirring guide blocks 5.

[0028] The present invention also includes a screen 7 at the bottom of the powder box assembly 4, a powder box side baffle 11 installed at the end of the powder box assembly 4 away from the motor box 1, and an outer bearing seat 12 of the powder box installed on one side of the powder box side baffle 11.

[0029] This utility model also includes a scraper weldment 13 provided on the lower part of one side of the powder box assembly 4.

[0030] This utility model also includes a motor speed controller 2 provided on one side of the motor housing 1.

[0031] When in use, the motor speed controller 2 can adjust the motor speed, thereby controlling the powder spreading speed.

[0032] In use, the motor inside the motor housing 1 provides power to the entire device. After the motor starts, its output end drives the brush shaft 8 to rotate. Due to the eccentricity of the shaft end of the brush shaft 8, the linkage component 10 sleeved on the shaft end will move accordingly with the rotation of the brush shaft 8. The linkage component 10 then drives the powder mixing component 6 connected to it to move. Because the powder mixing component 6 is installed inclined downward inside the powder box assembly 4 and is movably installed between the two powder mixing guide blocks 5, under the drive of the linkage component 10, The powder stirring component 6 can reciprocate within the powder box assembly 4, stirring the powder inside and effectively reducing powder caking. Simultaneously, the brush 9 on the outside of the brush shaft 8 rotates with the brush shaft 8. During the rotation of the brush 9, when the bristles of the brush 9 pass the powder scraping stud 16 horizontally installed inside the powder box assembly 4, the powder scraping stud 16 will bounce the brush 9, causing the powder caking at the end of the brush 9 to fall off, ensuring that the powder scraped off by the brush 9 from the screen 7 each time is fine and uniform.

[0033] In addition, the powder box assembly 4 is installed on one side of the powder box mounting base 3 via the powder box mounting plate 14, and can be completely disassembled by slightly rotating the outer bearing seat 12 of the powder box for easy cleaning. At the same time, the powder box mounting base 3 and the powder box assembly 4 are positioned and installed through the same mounting hole, which ensures high installation repeatability and no need for readjustment after disassembly and reinstallation, ensuring that the device can quickly return to normal working condition.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
