Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to a double-scraper automatic cotton cleaning structure. Background Technology

[0002] During the roving spinning process, a lot of cotton lint and lint are generated in the air and on the spinning equipment. If not cleaned in time, it will affect the health of workers and also affect the roving spinning process, making it prone to breakage. Therefore, it is necessary to clean up the cotton lint and lint in a timely manner. The traditional method is to install a spinning dust collector fan to collect the cotton lint and lint by sucking them in. The sucked-in cotton lint will be concentrated and attached to the dust screen around the motor, and then the collected cotton lint and lint will be cleaned manually. This manual cleaning method has the following problems: if the cleaning is not timely, the motor will overheat and cause damage. Secondly, incomplete manual cleaning will affect the suction effect, resulting in a decrease in the subsequent cotton suction effect. Utility Model Content

[0003] The purpose of this utility model is to provide a dual-scraper automatic cotton cleaning structure, which effectively solves the problem of untimely or incomplete cleaning of cotton threads on the dustproof mesh around the motor when cleaning manually.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] The dual-head automatic cotton cleaning structure includes a fan, a fan baffle, and a dustproof screen. The dustproof screen includes a filter frame and multiple filter planes, with an obtuse angle between adjacent filter planes. A cylinder assembly and a cotton scraping bracket assembly are provided on the dustproof screen. The cylinder assembly includes a lever cylinder, a cylinder bracket, and two guide rails, respectively located on the left and right sides of the filter frame. The lever cylinder is connected to the fan baffle via the cylinder bracket. The cotton scraping bracket assembly includes multiple interconnected "I"-shaped cotton scraping brackets adapted to the filter planes and two side reinforcing ribs on the left and right sides. The number of cotton scraping brackets is the same as the number of filter planes. The height of each cotton scraping bracket is half the length of the filter plane. One side of each of the two side reinforcing ribs is slidably connected to an adjacent guide rail, and the other side is connected to an adjacent cotton scraping bracket. Two vertically distributed rubber strip assemblies for cleaning cotton lint are provided on each cotton scraping bracket. The output shaft of the lever cylinder is connected to the cotton scraping bracket located in the middle.

[0006] Furthermore, the scraper bracket includes an upper scraper, a lower scraper, and a central reinforcing rib for connecting the upper scraper and the lower scraper. The top ends of both the upper scraper and the lower scraper are folded towards the filter screen plane and connected to the adhesive strip assembly.

[0007] Furthermore, the adhesive strip assembly includes a silicone strip and a U-shaped groove, the silicone strip being embedded in the U-shaped groove, and a gap existing between the silicone strip and the filter screen plane.

[0008] Furthermore, there are three filter screen planes and three cotton scraper supports, and the upper and lower scrapers of the three cotton scraper supports are integrally formed.

[0009] Furthermore, the central reinforcing rib includes an upper transverse connecting part, a lower transverse connecting part, and a vertical reinforcing part. The upper transverse connecting part and the lower transverse connecting part are respectively located at the upper and lower ends of the vertical reinforcing part. The upper transverse connecting part is bolted to the upper scraper, and the lower transverse connecting part is bolted to the lower scraper. The middle of the upper transverse connecting part, the lower transverse connecting part, and the vertical reinforcing part are all provided with through holes.

[0011] Furthermore, the free end of the silicone strip is pointed.

[0012] Furthermore, the output shaft of the pull rod cylinder is connected to the lower scraper of the cotton scraping bracket located in the middle position.

[0013] Compared with the prior art, the beneficial technical effects of this utility model are:

[0014] (1) This utility model effectively increases the cotton absorption area of ​​the dustproof net by changing the dustproof net from a single planar structure to a three-dimensional structure with multiple filter planes and an obtuse angle between adjacent filter planes.

[0015] (2) This utility model uses a cylinder-driven upper and lower double scraper and double rubber strip assembly to make the airflow disturbance more uniform. The scraped cotton debris can be more efficiently absorbed and transported by the fan airflow, reducing cotton debris residue and secondary entanglement, improving the cleanliness and continuity of automatic cotton cleaning, solving the problem of easy accumulation of cotton debris after traditional single scraper head cotton cleaning, and solving the problem of untimely or incomplete cleaning of cotton threads on the dustproof net around the motor when cleaning manually.

[0016] (3) By designing the free end of the silicone strip as a pointed tip and designing a certain gap between the silicone strip and the filter screen plane, this utility model can both scrape off the accumulated cotton layer and not damage the dustproof screen. Attached Figure Description

Detailed Implementation

[0022] Example 1: As Figure 1 and Figure 2 As shown, the dual-scraper automatic cotton cleaning structure includes a fan, a fan baffle 1, and a dustproof screen. The dustproof screen includes a filter frame 2 and three filter planes 3 surrounded by the filter frame 2. The included angle between adjacent filter planes 3 is an obtuse angle, and the filter planes 3 are made of stainless steel. By changing the dustproof screen from a single planar structure to a three-dimensional structure, the cotton absorption area of ​​the dustproof screen is effectively increased.

[0023] The dustproof screen is equipped with a cylinder assembly and a scraper support assembly. The cylinder assembly includes a pull rod cylinder 4, a cylinder support 5, and two guide rails 6. The two guide rails 6 are respectively located on the left and right sides of the filter frame 2. The pull rod cylinder 4 is connected to the fan partition 1 through the cylinder support 5.

[0024] like Figure 1 and Figure 3 As shown, the scraper support assembly includes three interconnected "I"-shaped scraper supports 7 and two side reinforcing ribs 8 located on the left and right sides. Each filter screen plane 3 is fitted with one scraper support 7, and the height of the scraper support 7 is approximately half the length of the filter screen plane 3. One side of each of the two side reinforcing ribs 8 is slidably connected to an adjacent guide rail 6 via a slider 9, and the other side of each of the two side reinforcing ribs 8 is connected to an adjacent scraper support 7.

[0025] In this embodiment, as Figure 1 and Figure 3As shown, the cotton scraping bracket 7 includes an upper scraper 10, a lower scraper 11, and a central reinforcing rib 12 for connecting the upper scraper 10 and the lower scraper 11. The upper scraper 10 and lower scraper 11 of the three cotton scraping brackets 7 are all integrally formed. The output shaft of the pull rod cylinder 4 is connected to the lower scraper 11 of the cotton scraping bracket 7 located in the middle position. The top ends of the upper scraper 10 and the lower scraper 11 of the cotton scraping bracket 7 are folded towards the filter screen plane 3 and connected to the rubber strip assembly 13 for cleaning cotton lint. Under the action of the pull rod cylinder 4, the cotton scraping bracket 7 drives the rubber strip assembly 13 to slide up and down along the guide rail 6 to complete the up and down cotton scraping action. Through the design of the upper and lower double scraper and double rubber strip assembly, the cotton cleaning efficiency can be improved, and the airflow disturbance can be more uniform. The scraped cotton lint can be more efficiently absorbed and transported by the fan airflow, reducing cotton lint residue and secondary entanglement, improving the cleanliness and continuity of automatic cotton cleaning, and solving the problem of easy accumulation of cotton lint after traditional single scraper head cotton cleaning.

[0026] In this embodiment, as Figure 4 As shown, the adhesive strip assembly 13 includes a silicone strip 14 and a U-shaped groove 15 made of aluminum alloy. The silicone strip 14 is embedded in the U-shaped groove 15. The free end of the silicone strip 14 is pointed, and there is a certain gap between the silicone strip 14 and the filter screen plane 3. This allows the accumulated cotton layer to be scraped off without damaging the dustproof screen.

[0027] In this embodiment, as Figure 3 As shown, the central reinforcing rib 12 is integrally formed and includes an upper transverse connecting part, a lower transverse connecting part, and a vertical reinforcing part. The upper and lower transverse connecting parts are respectively located at the upper and lower ends of the vertical reinforcing part. The upper transverse connecting part is bolted to the upper scraper 10, and the lower transverse connecting part is bolted to the lower scraper 11. Both the upper and lower transverse connecting parts have an elongated through hole 16 in the middle, and the vertical reinforcing part has two vertically arranged through holes 16 in the middle. The central reinforcing rib 12 can stably connect the upper scraper 10 and the lower scraper 11, ensuring the structural strength and stability of the silicone strip 14 during operation; at the same time, the reasonable hollow and open design reduces the overall weight, which is conducive to integration with the fan, transmission, and pneumatic system, optimizes the equipment space layout, and reduces the difficulty of installation and adaptation.

[0028] In this embodiment, the adhesive strip assembly 13 and the cotton scraper bracket 7 are connected by precise mounting holes, which facilitates quick disassembly and replacement. The adhesive strip assembly 13 can be flexibly replaced according to the characteristics of the cotton material (such as different fiber lengths and impurity types), thereby improving the equipment's compatibility with various production scenarios.

[0029] The working principle of this invention is as follows: When the lever cylinder 4 is activated, it drives the scraper bracket assembly and the rubber strip assembly to move up and down along the guide rail 6 on the corresponding filter screen plane 3, thereby scraping off the cotton debris on the dust screen. The design of the upper and lower double scrapers and double rubber strip assembly makes the airflow disturbance more uniform, allowing the scraped cotton debris to be more efficiently absorbed and transported by the fan airflow, reducing cotton debris residue and secondary entanglement, improving the cleanliness and continuity of automatic cotton cleaning, and solving the problem of cotton debris accumulation after traditional single-scraper head cleaning.

[0030] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
