Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, specifically relating to a down cleaning device for down production. Background Technology

[0002] Down refers to the downy feathers from the abdomen and back of poultry, specifically the feathers and down of ducks, geese, etc., after washing and other processing. Collected feathers and down often contain impurities such as wing shafts, debris, and ash. Washing effectively separates and removes these impurities, improving the purity of the down. Raw down may carry odors and microorganisms such as bacteria and mold; the washing process achieves sterilization, ensuring the hygiene and safety of the final product. In short, the washing process in down production is not just simple cleaning, but a crucial step in ensuring the purity, loft, and hygiene of the down.

[0003] Chinese invention patent CN114990703A discloses a down processing and washing device, including a washing tub, a water outlet pipe, a lid, a filter screen, a washing mechanism, and a contacting mechanism. The washing tub has a discharge port on the top right side, a water outlet pipe connected to the middle of the bottom of the tub, and a lid threadedly connected to the lower right side of the rear wall of the tub. A filter screen is connected inside the water outlet pipe. The washing tub is equipped with a washing mechanism for transporting down, and a contacting mechanism that works with the washing mechanism to wash the down. This invention saves time and labor by using a washing belt to rotate a washing ball, which, in conjunction with a soft cloth, automatically washes the down.

[0004] However, after the down processing and washing device automatically washes the down, down remains on the washing belt and the soft cloth, making cleaning inconvenient. Summary of the Invention

[0005] To address the problems existing in the background art, the present invention provides a down cleaning device for down production, which can both automatically rub and wash the down and clean itself.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A down cleaning device for down production includes a cleaning tank and a conveyor belt rotatably disposed within the cleaning tank for conveying down, and further includes a close-contact rubbing mechanism disposed below the conveyor belt, comprising: Several strips of cloth are arranged in parallel along the transmission direction of the transmission belt, and the strips are arranged along the rotation axis of the transmission belt. A connecting plate that connects to the end of the fabric strip; A shaft is set along the length of the fabric strip and one end is connected to the connecting plate; A drive mechanism is installed on the cleaning tank and its output end is driven to the other end of the shaft. When the drive mechanism drives the shaft to rotate around its central axis, it drives the connecting plate and the cloth strip to rotate together, and makes the cloth strip contact the transmission belt.

[0007] Furthermore, the driving mechanism includes a rotating drum rotatably mounted on the cleaning tank and a drive motor mounted on the cleaning tank for driving the rotating drum to rotate around its central axis. A strip-shaped hole is formed inside the rotating drum along its length direction. The cross-section of the strip-shaped hole is rectangular. The shaft is movably mounted in the rectangular hole. A rectangular slider is provided at the end of the shaft away from the cloth strip. The rectangular slider slides in the strip-shaped hole along its length direction. A tension spring is provided between the end of the rotating drum away from the cloth strip and the rectangular slider.

[0008] Furthermore, a through groove communicating with the strip hole is formed on the rotating drum along its length direction, and a limiting block is provided on the rectangular slider. The limiting block passes through the through groove and extends to the outside of the through groove. A baffle is provided on the washing tank. The baffle is located below the rotating drum and abuts against the limiting block to restrict the limiting block from moving towards the cloth strip.

[0009] Furthermore, the top of the baffle is provided with a beveled surface.

[0010] Furthermore, a retaining ring is provided inside the strip-shaped hole. The retaining ring is fixedly connected to the inner side wall of the rotating cylinder. The retaining ring abuts against the rectangular slider to restrict the rectangular slider from moving away from the fabric strip.

[0011] Furthermore, a sprocket is fitted around the circumference of the rotating drum, and a chain meshes with the sprocket to make several sprockets rotate synchronously.

[0012] Furthermore, a plurality of washing protrusions are evenly arranged on the outer surface of the transmission belt.

[0013] Furthermore, the top of the cleaning tank has a feed inlet with a feed cover plate; the bottom of the cleaning tank has a drain outlet with a drain pipe, a filter screen is installed at the top of the drain pipe, and a valve is also installed inside the drain pipe; discharge outlets are opened on opposite side walls of the cleaning tank with discharge covers plate.

[0014] Furthermore, both the feed cover and the discharge cover are hinged to the cleaning box.

[0015] Furthermore, the down cleaning device for down production has two typical operating states: Down washing status: Both ends of the cloth strip are fixed and the cloth strip itself is in a taut state. The cloth strip and the transmission belt form a down washing chamber. The transmission belt rotates and cooperates with the cloth strip to automatically wash the down in the down washing chamber. After the down is cleaned, it enters the self-cleaning state; the drive mechanism drives the cloth strip to rotate 90 degrees relative to the down cleaning state. The down in the down scrubbing chamber formed between the transmission belt and the cloth strip falls to the bottom of the cleaning box through the gap between the adjacent cloth strips. The end of the cloth strip contacts the surface of the transmission belt. As the transmission belt rotates, the cloth strip scrapes off the down remaining on the surface of the transmission belt. At the same time, the cloth strip vibrates, shaking off the down remaining on the cloth strip itself and the down scraped off the surface of the transmission belt.

[0016] This application has the following beneficial effects: This invention features a close-fitting washing mechanism, enabling the down washing device used in down production to operate in two typical states: a down washing state and a self-cleaning state. In the down washing state, both ends of all the fabric strips are fixed and taut. This allows the "fabric" formed by the parallel arrangement of all the strips to create a down washing chamber between itself and the conveyor belt. The conveyor belt drives the washing convex balls to rotate in conjunction with the fabric strips, thus automatically washing the down.

[0017] After the down is washed, it enters the self-cleaning state. All the cloth strips rotate 90 degrees relative to their washing state, so that the down in the down washing chamber formed between the conveyor belt and all the cloth strips can fall to the bottom of the washing tank through the gaps created between adjacent cloth strips. At this time, the ends of the cloth strips contact the surface of the conveyor belt, and the conveyor belt drives the washing cams to rotate, cooperating with multiple cloth strips. The cloth strips scrape off the down remaining on the surface of the conveyor belt, cleaning the conveyor belt surface. In this process, the cloth strips also vibrate, shaking off the down remaining on the cloth strips themselves and the down scraped off the surface of the conveyor belt, thus achieving the self-cleaning effect.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0021] An embodiment of a down cleaning device for down production provided by the present invention: A down cleaning device for down production, such as... Figure 1 As shown, the system includes a cleaning tank 1, with support legs installed at each of the four corners of its bottom to ensure stable placement and appropriate height. An inlet is located at the top of the cleaning tank 1 for adding cleaning solution, water, and down feathers to be cleaned; a hinged inlet cover 2 is installed on the inlet cover for easy opening and closing as needed. A drain outlet is located at the bottom of the cleaning tank 1, with a drain pipe 3 installed on it. A filter screen 4 is installed at the top of the drain pipe 3, and a valve 5 is also installed inside the drain pipe 3. After cleaning, when drainage is required, valve 5 is opened for smooth drainage, and the filter screen 4 can trap the cleaned down feathers inside the cleaning tank, preventing loss of down feathers with the wastewater. Discharge outlets are located on opposite side walls of the cleaning tank 1, with the bottom of the outlet at the same height as the top of the bottom plate of the cleaning tank for easy discharge. A discharge cover 6 is hinged to the discharge outlet. After the drainage is complete and the washed down is intercepted by the filter screen 4 in the washing box, open the two discharge covers 6, and use the external push plate to extend into the washing box 1 from one discharge port to push the down gathered at the bottom of the washing box 1 out to the outside and collect it.

[0022] like Figure 2 As shown, a transmission belt 7 for conveying down is rotatably installed inside the washing tank 1. Several washing protrusions 8 are evenly installed on the outer surface of the transmission belt 7. Specifically, a drive roller and a driven roller are rotatably installed at the same height inside the washing tank 1, and the transmission belt 7 is mounted on the drive roller and the driven roller. A motor is installed on the washing tank 1, and the output end of the motor is connected to the drive roller. When the motor is turned on, it drives the drive roller to rotate, which in turn drives the driven roller to rotate via the transmission belt 7. This allows the down falling onto the transmission belt 7 to be conveyed.

[0023] like Figures 3-7 As shown, it also includes a close-fitting washing mechanism installed below the transmission belt 7, which includes multiple strips 9 arranged side by side along the transmission direction of the transmission belt 7, each strip 9 being arranged along the axial direction of the drive roller. A connecting plate 10 is connected to the end of each strip 9. A shaft 11 is connected to the connecting plate 10, the shaft 11 being arranged along the length of the strip 9 and having one end connected to the connecting plate 10. A drive mechanism is also installed on the washing tank 1, with its output end connected to the other end of the shaft 11. When the drive mechanism drives the shaft 11 to rotate around its central axis, it causes the connecting plate 10 and the strips 9 to rotate together, bringing the strips 9 into contact with the transmission belt 7.

[0024] Specifically, the drive mechanism includes a fixed base 15 fixedly mounted on the washing tank 1, a rotating drum 13 rotatably mounted on the fixed base 15 via bearings, and a drive motor 22 mounted on the washing tank 1 and used to drive the rotating drum 13 to rotate around its central axis. Note that not every rotating drum is equipped with a corresponding drive motor 22; rather, only the two rotating drums 13 at both ends of a certain strip of fabric 9 are each connected to a drive motor 22. A sprocket 20 is mounted circumferentially on the rotating drum 13, and a chain 21 meshes with the sprocket 20 so that the sprockets 20 rotate synchronously, thereby driving the sprockets 9 to rotate synchronously.

[0025] A strip-shaped hole is opened inside the rotating cylinder 13 along its length direction. The cross-section of the strip-shaped hole is rectangular. The shaft 11 is movably inserted into the rectangular hole. The end of the shaft 11 away from the cloth strip 9 is connected to the rectangular slider 12. The rectangular slider 12 slides in the strip-shaped hole along its length direction. A tension spring 14 is connected between the end of the rotating cylinder 13 away from the cloth strip 9 and the rectangular slider 12.

[0026] A through groove 16 communicating with a strip-shaped hole is formed along the length of the rotating drum 13. A limiting block 17 is connected to the rectangular slider 12, passing through the through groove 16 and extending to the outside of the through groove 16. A baffle 18 is installed on the washing tank 1, located below the rotating drum 13. The baffle 18 abuts against the limiting block 17 to restrict the limiting block 17 from moving towards the fabric strip 9. The top of the baffle 18 has a beveled surface 19. A retaining ring is installed inside the strip-shaped hole, fixedly connected to the inner wall of the rotating drum 13. The retaining ring abuts against the rectangular slider 12 to restrict the rectangular slider 12 from moving away from the fabric strip 9.

[0027] The down cleaning device of the present invention for down production has two typical operating states during use: In the down washing state, both ends of all the fabric strips 9 are fixed and taut. In this way, the "cloth" formed by all the fabric strips 9 arranged side by side can form a down washing chamber with the transmission belt 7. The transmission belt 7 drives the washing balls 8 to rotate in conjunction with the fabric strips 9, so that the down can be automatically washed.

[0028] After the down is washed, it enters a self-cleaning state. All the cloth strips 9 rotate 90 degrees relative to their washing state, so that the down in the down washing chamber formed between the conveyor belt 7 and all the cloth strips 9 can fall to the bottom of the washing tank 1 through the gaps created between adjacent cloth strips 9. Furthermore, the ends of the cloth strips 9 contact the surface of the conveyor belt 7, and the conveyor belt 7 drives the washing convex balls 8 to rotate in conjunction with the multiple cloth strips 9. The cloth strips 9 scrape off the down remaining on the surface of the conveyor belt 7, thus cleaning the surface of the conveyor belt 7. During this process, the cloth strips 9 also vibrate, shaking off the down remaining on the cloth strips 9 themselves and the down scraped off the surface of the conveyor belt 7, thereby achieving a self-cleaning effect.

[0029] Working principle: The fabric strip 9 is flexible but has excellent tensile strength, meaning that its length and width will not change when subjected to external force. The material of the fabric strip 9 can be carbon fiber woven fabric, aramid woven fabric, high-strength canvas, etc. The center of the shaft 11 coincides with the centerline of the top surface of the fabric strip 9; both the feed cover plate 2 and the discharge cover plate 6 are equipped with latches, which can keep the feed cover plate 2 and the discharge cover plate 6 in the closed or open state.

[0030] At this time, the arrangement of multiple strips 9 is as follows: Figure 2 and Figure 4As shown, the multiple fabric strips 9 are connected in an initial state, with a small gap between them to prevent down from passing through. This gap is designed to avoid motion interference when the multiple fabric strips 9 rotate around the shaft 11. The motor shaft of the drive motor 22 is self-locking; that is, when the drive motor 22 is off, its shaft is fixed. With the drive motor 22 off and its shaft fixed, the connected rotating drum 13 is also fixed. Through the cooperation of multiple sprockets 20 and chains 21, the other rotating drums 13 are also fixed, meaning none of the rotating drums 13 can rotate relative to the fixed base 15. Consequently, the rectangular slider 12, shaft 11, connecting plate 10, and fabric strips 9 cannot rotate relative to the washing tank 1. At this time, the rectangular slider 12 is in contact with the retaining ring inside the rotating drum 13 and cannot move to the right. Furthermore, at this time, the limiting block 17 cannot move to the left under the restriction of the baffle 18. Thus, the rectangular slider 12 and the limiting block 17 cannot slide horizontally relative to the rotating cylinder 13, and consequently, the ends of the shaft 11, connecting plate 10, and cloth strip 9 cannot slide horizontally relative to the rotating cylinder 13. At this time, both ends of the multiple cloth strips 9 are in a taut and straight state and are in a fixed state. Simply put, the cloth strip 9 can now be understood as a rigid plate.

[0031] In use, open the feed cover 2 and add an appropriate amount of water mixed with washing solution to the washing tank 1, so that the liquid level in the washing tank 1 is higher than the top surface of the transmission belt 7. Then, control the drive motor 22 to rotate to bring the device to its initial state. Next, put an appropriate amount of down into the washing tank 1, placing it on the transmission belt 7. Then, start the transmission belt 7 to rotate counterclockwise, transporting the down to the left, so that the down enters the cavity formed by the transmission belt 7 and multiple cloth strips 9. In this way, the transmission belt 7 drives the washing ball 8 to rotate, cooperating with the multiple cloth strips 9 to automatically wash the down.

[0032] After cleaning, the two drive motors 22 are started, which drive the two rotating drums 13 to rotate synchronously. The rotating drums 13 drive the chain 21 through the sprocket 20, and the chain 21 drives multiple rotating drums 13 to rotate, that is, multiple rotating drums 13 will rotate synchronously clockwise. Figure 7 (clockwise) The rotating drum 13 drives the rectangular slider 12, the limit block 17, the shaft 11, the connecting plate 10, and the fabric strip 9 to rotate synchronously. After driving the fabric strip 9 to rotate 90 degrees clockwise, the drive motor 22 is turned off. At this time, all the fabric strips 9 have rotated 90 degrees, and the state is as follows. Figure 8 As shown, this is the state of strip 9 after it has been rotated 90 degrees clockwise. Figure 8The center of the central shaft 11 coincides with the centerline of the top surface of the fabric strip 9. This allows the top of the fabric strip 9 to contact the surface of the transmission belt 7 after rotating 90 degrees clockwise around the shaft 11, without any motion interference during this rotation. After the rotating drum 13 drives the fabric strip 9 to rotate 90 degrees, the limiting block 17 and the baffle 18 are completely misaligned, and the baffle 18 no longer obstructs the limiting block 17. At this time, the rectangular slider 12, shaft 11, connecting plate 10, and the end of the fabric strip 9 have the freedom to slide horizontally relative to the rotating drum 13. However, under the pulling action of the tension spring 14, the fabric strip 9 will still remain taut. At this time, the down in the cavity formed by the transmission belt 7 and the multiple fabric strips 9 will fall into the bottom of the washing tank 1 through the gaps between the multiple fabric strips 9. At the same time, the valve 5 is opened, allowing the water in the washing tank 1 to be discharged through the drain pipe 3. With the filter screen 4, the down can be prevented from being discharged as well. At the same time, the transmission belt 7 drives multiple washing balls 8 to continue moving. During the movement of the transmission belt 7 relative to multiple cloth strips 9, the cloth strips 9 can scrape off the residual down on the surface of the transmission belt 7, thus cleaning the surface of the transmission belt 7.

[0033] After the washing protrusions 8 on the surface of the transmission belt 7 come into contact with the cloth strip 9, the washing protrusions 8 push the cloth strip 9 to move together. The end of the cloth strip 9 drives the connecting plate 10, the shaft 11, and the rectangular slider 12 to move inward relative to the rotating drum 13, and the tension spring 14 is stretched. As the washing protrusions 8 continue to move, they will pass over the cloth strip 9, and the cloth strip 9 will no longer be pushed by the washing protrusions 8. Then, under the action of the tension spring 14, it will quickly return to its original state. That is, the tension spring 14 will pull the rectangular slider 12, the shaft 11, the connecting plate 10, and the end of the cloth strip 9 to move outward quickly, so that the cloth strip 9 quickly returns to a taut state. In this process, the cloth strip 9 itself will vibrate, shaking off the down remaining on the cloth strip 9 and the down scraped off the surface of the transmission belt 7, which will fall below the washing tank 1.

[0034] Afterwards, the drive belt 7 is closed, and the two discharge covers 6 are opened. An external pusher plate extends into the cleaning tank 1 from one discharge port, pushing the down accumulated at the bottom of the cleaning tank 1 out through the other discharge port for collection, ready for the next processing operation. Then, the feed cover 2 can be opened to inject clean water into the cleaning tank 1 to rinse its interior. During rinsing, the drive belt 7 can be activated, causing the multiple fabric strips 9 to vibrate, resulting in a better cleaning effect. After rinsing in the cleaning tank 1, add an appropriate amount of water mixed with washing liquid to the cleaning tank 1 so that the liquid level in the cleaning tank 1 is higher than the top surface of the transmission belt 7. Then, control the two drive motors 22 to rotate in opposite directions, driving multiple rotating drums 13 and multiple cloth strips 9 to rotate 90 degrees in the opposite direction before shutting off. At this time, the device returns to its initial state. During the reset process, through the setting of the inclined surface 19, the limit block 17 can be reset better under the guidance of the inclined surface 19. Then, put an appropriate amount of down into the cleaning tank 1 and place it on the transmission belt 7. Then, start the transmission belt 7 to perform a new cleaning cycle.

[0035] In the above description, especially when discussing the movement of the fabric strips 9, the description focuses on the multiple fabric strips 9 located directly below the transmission belt 7. The multiple fabric strips 9 in an arc shape located on both sides are not described. The multiple fabric strips 9 located on both sides can be seen from... Figure 2 and Figure 4 As can be seen, both the cloth strips 9 and the connecting plate 10 are arc-shaped, with their centers coinciding with the center of the transmission belt 7. Due to the shape of these cloth strips 9, after rotating 90 degrees, their ends will not make close contact with the surface of the transmission belt 7, leaving a certain gap. Therefore, during the subsequent movement of the multiple washing protrusions 8 driven by the transmission belt 7, these cloth strips 9 will not scrape or clean the surface of the transmission belt 7. However, these cloth strips 9 will still contact the washing protrusions 8 and vibrate under their influence, shaking off any residual down. Although these cloth strips 9 cannot scrape the surface of the transmission belt 7, the multiple cloth strips 9 located directly below the transmission belt 7 can, as long as there are cloth strips 9 that can scrape the transmission belt 7. Therefore, even if the cloth strips 9 located on both sides cannot scrape the transmission belt 7, it does not affect the overall cleaning effect.

[0036] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
