Description

Technical Field

[0001] This utility model belongs to the technical field of dust removal equipment, specifically, it relates to a thin plate conveying mechanism and a wind knife dust removal device. Background Technology

[0002] As a key piece of equipment for ensuring product surface cleanliness, the performance adaptability of air knife dust removal equipment directly affects production efficiency and product quality. Air knife dust removal mainly relies on airflow forming an airflow curtain through the air knife nozzles to sweep the product surface, thereby peeling off and removing dust, impurities, and other adhering substances. However, when thin sheet products are conveyed to the upper and lower air knife inlets, the suction and blowing air generated by the air knives cause the products to shake up and down, resulting in product scratches and jamming. Therefore, improvements are necessary. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] One embodiment of this application provides a thin plate conveying mechanism for an air knife dust removal device, such as... Figures 1-5 As shown, it includes: frame 1, which serves as a support;

[0028] The first transmission unit 2 is rotatably connected to the frame 1;

[0029] The second transmission unit 3 is rotatably connected to the frame 1;

[0030] The first conveying unit 2 and the second conveying unit 3 are symmetrically arranged on the frame 1; the first conveying unit 2 and the second conveying unit 3 are spaced apart; a dust removal channel 11 is formed between the first conveying unit 2 and the second conveying unit 3.

[0031] In use, the first conveying unit 2 and the second conveying unit 3 are located between the upper air knife 4 and the lower air knife 5 of the air knife dust removal equipment; the first conveying unit 2 and the second conveying unit 3 are used for conveying thin plate products. The thin plate products to be dusted enter the dust removal channel 11 between the first conveying unit 2 and the second conveying unit 3, and the upper air knife 4 and the lower air knife 5 of the air knife dust removal equipment remove dust from them. Then, the dust-removed thin plate products are conveyed to the next process. It should be noted that the structure and working process of the air knife dust removal equipment are existing technologies and will not be described in detail here.

[0032] Specifically, such as Figure 3As shown, the structure of the second conveying unit 3 is symmetrical to that of the first conveying unit 2. The first conveying unit 2 includes a first rotating shaft 21 and a second rotating shaft 22 rotatably connected to the frame 1. The first rotating shaft 21 and the second rotating shaft 22 are spaced apart, and the second rotating shaft 22 is located below the first rotating shaft 21. A plurality of first conveying wheels 23 are spaced apart on the first rotating shaft 21, and a plurality of second conveying wheels 24 are spaced apart on the second rotating shaft 22. The first conveying wheels 23 and the second conveying wheels 24 correspond one-to-one, that is, one second conveying wheel 24 is directly below one first conveying wheel 23. A conveying channel is formed between the first conveying wheels 23 and the second conveying wheels 24 for conveying the products to be dusted. The diameter of the first conveying wheel 23 is the same as the diameter of the second conveying wheel 24.

[0033] To ensure a large transmission area in the transmission channel, at least two first rotating shafts 21 are arranged side by side, and the number of second rotating shafts 22 is the same as the number of first rotating shafts 21, ensuring smooth transmission. It should be noted that in use, the first rotating shafts 21 and the second rotating shafts 22 are connected to the drive device, and the drive device drives the first rotating shafts 21 and the second rotating shafts 22 to rotate at a preset speed. This is existing technology and will not be described in detail here.

[0034] like Figures 3-5 As shown, a plurality of first limiting components 25 are spaced apart on the first rotating shaft 21, and a plurality of second limiting components 26 are spaced apart on the second rotating shaft 22. Both the first limiting components 25 and the second limiting components 26 are located within the dust removal channel 11 formed by the first conveying unit 2 and the second conveying unit 3. The first limiting components 25 and the second limiting components 26 correspond one-to-one, and there is a gap between them. This gap is the same size as the conveying channel formed between the first conveying wheel 23 and the second conveying wheel 24, and is used for thin plates. As the product passes through, the first limiting component 25 and the second limiting component 26 limit the vertical displacement of the thin plate product. The structure of the second limiting component 26 is symmetrical to that of the first limiting component 25. The first limiting component 25 includes a limiting bracket 251 rotatably connected to the first rotating shaft 21. The end of the limiting bracket 251 near the air knife dust removal equipment extends to form a mounting bracket 252. One or more limiting rollers 253 are connected to the mounting bracket 252. The diameter of the limiting rollers 253 is smaller than the diameter of the first conveyor wheel 23.

[0035] The limiting roller 253 is rotatably connected to a roller bracket 254, which is connected to the mounting bracket 252. As an example, there are three limiting rollers 253, and the centers of the three limiting rollers 253 are connected in sequence on the same projection plane to form a triangle. This allows the limiting component to limit the thin plate product and prevent it from shaking during the dust removal process.

[0036] In one embodiment, such as Figure 1 and Figure 3 As shown, it also includes a first conveying component 6 and a second conveying component 7. The first conveying component 6 is located on the side of the first conveying unit 2, and the second conveying component 7 is located on the side of the second conveying unit 3. The first conveying component 6 is used for the entry of the product to be dusted, and the second conveying component 7 is used for the output of the product after dust removal. The structure of the second conveying component 7 is the same as that of the first conveying component 6. The first conveying component 6 includes a plurality of first conveying shafts 61, which are rotatably connected to the frame 1 at intervals. A plurality of first conveying wheels 62 are spaced apart on the first conveying shafts 61, and the first conveying wheels 62 on adjacent first conveying shafts 61 are staggered to ensure smooth conveying. It should be noted that in use, the first conveying shafts 61 are connected to the driving device, and the driving device drives the first conveying shafts 61 to rotate. This is prior art and will not be described in detail here.

[0037] In this embodiment, when the thin plate is being dusted, the first limiting component 25 and the second limiting component 26 work together to effectively prevent the thin plate product from being scratched or jammed due to the suction and blowing generated by the upper air knife 4 and lower air knife 5 when it is conveyed to the air knife dust removal equipment. This achieves the ability of the air knife cleaning equipment to clean thin plates and improves production efficiency.

[0038] One embodiment of this application provides an air knife dust removal device, which includes a thin plate conveying mechanism for air knife dust removal devices as described above.

[0039] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
