Description

A screen cleaning mechanism for a down sorting machine used in down production Technical Field

[0001] This utility model relates to the field of down production technology, specifically to a screen cleaning mechanism for a down sorting machine used in down production. Background Technology

[0002] As is well known, down production requires the use of a feather sorting machine to break down, screen, and grade the down. The auxiliary tool used in the feather sorting machine is a screen. After prolonged use, the screen is prone to clogging. Once clogged, the down cannot be screened, and the screen usually needs to be cleaned to ensure its normal use.

[0003] A search of the screen cleaning mechanism for a down sorting machine used in down production, published under publication number CN217392984U, revealed the following shortcomings:

[0004] When the screen plate needs to be cleaned, the second lead screw is rotated, and the second lead screw nut moves the push plate upward, so that the bristles on the upper part of the push plate are in contact with the lower screen surface. At this time, the push plate can be moved by the hydraulic rod to make the bristles clean the lower side of the screen plate.

[0005] Therefore, in existing technologies, the method of using brushes on a scraper to clean only the underside of the screen is ineffective. Since down cleaning requires it to pass through the screen mesh, cleaning only from the bottom wall makes it difficult for the down to effectively pass through the mesh, resulting in a large amount of down remaining on the screen. This not only leads to low cleaning efficiency but also hinders the complete removal of down. This not only consumes significant manpower and time costs but also reduces the continuity and efficiency of the overall production process, failing to meet the actual production needs for efficient and thorough screen cleaning. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a screen cleaning mechanism for a down sorting machine used in down production, which greatly improves the efficiency and thoroughness of down cleaning and significantly reduces the difficulty and cost of cleaning.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a screen cleaning mechanism for a down sorting machine used in down production, including a machine housing, a screen, and several guide shafts. The screen has a screening function, and the screen is connected end to end to form a closed ring structure. The several guide shafts are arranged on the running path of the screen, and the screen is sleeved on the several guide shafts and rotates continuously along the direction of the guide shafts. When cleaning the screen, rotating the screen can turn the screening part to the bottom, causing the down on the screen to fall off for easy cleaning.

[0010] Furthermore, the top of the chassis is provided with a feed inlet, and the bottom of the chassis is provided with a discharge outlet.

[0011] Furthermore, a discharge valve is provided at the discharge port.

[0012] Furthermore, a scraper is fixedly installed inside the casing to scrape the down off the screen.

[0013] Furthermore, the machine casing is equipped with pipes, and nozzles are installed on the pipes. The spray from the nozzles cleans the screen, and a connecting pipe is connected to the pipes.

[0014] Furthermore, one of the guide shafts is positioned significantly lower than the other guide shafts, causing the bottom of the screen to form a pointed structure under the action of the guide shaft.

[0015] Furthermore, a drive motor is fixedly mounted on the chassis, and the rotating end of the drive motor is concentrically connected to the corresponding guide shaft.

[0016] Furthermore, the chassis has a switch door, and the switch door is provided with a window.

[0017] Furthermore, the bottom of the chassis is provided with support legs.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a screen cleaning mechanism for a down sorting machine used in down production, which has the following beneficial effects:

[0020] This invention relates to a screen cleaning mechanism for a down sorting machine used in down production. By setting the screen in a closed ring structure with its ends connected, and cooperating with several guide shafts to achieve continuous rotation, the cleaning mechanism can easily rotate the part used for screening to the bottom, allowing the down on the screen to fall naturally under gravity. Compared to existing technologies that only clean from the bottom wall of the screen, this significantly improves the efficiency and thoroughness of down cleaning, and reduces down residue.

[0021] With the down feathers falling naturally, simple cleaning methods such as vibration, blowing, and scraping can further clean the screen. These auxiliary methods are easy to operate, do not require complicated equipment and technology, and greatly reduce the difficulty and cost of cleaning.

[0022] While the cleaning section of the screen is being cleaned, other sections can continue screening normally. This efficient and convenient cleaning process improves the continuity and efficiency of the overall production process, saves time and costs for enterprises, and enhances economic benefits.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please refer to Figures 1-3. This utility model discloses a screen cleaning mechanism for a down sorting machine used in down production. It includes a housing 1, a switch door 4 on the housing 1 with a window 12, support legs 5 at the bottom of the housing 1, a feed inlet 13 at the top of the housing 1, and a discharge outlet 6 at the bottom of the housing 1, with a discharge valve 7 at the discharge outlet 6.

[0029] It also includes a screen 2 connected end to end in a ring shape and several guide shafts 3. The screen 2 has a screening function, and its end to end is connected to form a closed ring structure, similar to the shape of a conveyor belt. Several guide shafts 3 are set on the running path of the screen 2 to guide the rotation of the screen 2. The screen 2 is fitted on several guide shafts 3 and can rotate continuously along the direction of the guide shafts 3. Through this rotation, the material moves on the screen 2 and the screening process is realized. When cleaning the screen 2, the screening part can be rotated to the bottom by rotating the screen 2, causing the down on the screen 2 to fall off for easy cleaning. Other parts of the screen 2 can perform screening work normally. A drive motor 14 is fixedly installed on the housing 1. The rotating end of the drive motor 14 is concentrically connected to the corresponding guide shaft 3. The drive motor 14 is used to drive the screen 2 to rotate.

[0030] Furthermore, to facilitate the cleaning of the screen 2, one of the guide shafts 3 is positioned significantly lower than the other guide shafts 3. This causes the bottom of the screen 2 to form a pointed structure under the action of the guide shaft 3. At this time, the attachment surface of the screen 2 will face downward and bend, which is more conducive to the fall of down.

[0031] With the down feathers falling naturally, the screen can be cleaned even more thoroughly by simply vibrating, blowing, or scraping.

[0032] Vibration cleaning: Staff can manually tap the screen or use a vibrating motor to press against the screen, which helps the down fall off.

[0033] Scraping cleaning method: A scraper 8 is fixedly installed inside the casing 1 to scrape off the down on the surface of the screen 2.

[0034] Cleaning by spraying: The machine housing 1 is equipped with a pipe 9, and a nozzle 10 is installed on the pipe 9. The spray from the nozzle 10 cleans the screen 2 to blow off the down on the surface of the screen 2. A connecting pipe 11 is connected to the pipe 9 and is connected to an air pump.

[0035] In summary, when using this down sorting machine screen cleaning mechanism for down production, after the screening work is completed, the screen 2 is rotated to move the part that was just screened to the bottom. At this time, most of the down on the screen 2 will fall naturally under the action of gravity.

[0036] Assisted cleaning: To further clean up any remaining down, the following auxiliary methods can be selected depending on the actual situation.

[0037] Vibration cleaning: The screen 2 is appropriately vibrated by the staff by patting or using a vibrator to make the residual down fall out of the mesh of the screen 2.

[0038] Blow-off cleaning: Use nozzle 10 to spray high-pressure gas from above or inside the screen 2 to blow off any remaining down. Note that the blowing pressure should not be too high to avoid damaging the screen 2 or blowing up the down.

[0039] Scraping and cleaning: Use a scraper 8 made of soft material (such as a rubber scraper 8). As the screen 2 rotates, the surface of the screen 2 comes into contact with the scraper 8 to scrape off the residual down.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
