Description

Technical Field

[0001] This invention belongs to the field of down processing technology, and specifically relates to a down slugging and sorting device for down processing. Background Technology

[0002] Down is a natural animal protein fiber formed from the down feathers of waterfowl such as geese and ducks. It consists of supportive "feathers" and insulating "down" and is widely used as filling for down jackets, down comforters, and other products. Down needs to be sorted during the processing and production of down. However, down often clumps together after washing and drying, so it is often necessary to break it into smaller clumps before sorting.

[0003] Currently, down clumping and sorting are mostly done separately. First, the down is clumped and broken up manually or with simple equipment, and then the clumped down is transferred to sorting equipment for further sorting. This process is cumbersome and inefficient.

[0004] Meanwhile, when using airflow sorting, three or even more boxes are needed until the fine fibers that meet the requirements are screened out. The equipment has high technical requirements, occupies a large area, requires a lot of production investment, and has a small application range.

[0005] Therefore, there is an urgent need to design a down sorting device that can quickly obtain small down feathers. Summary of the Invention

[0006] The purpose of this invention is to provide a down balling and sorting device for down processing in order to solve the problems mentioned in the background art.

[0007] The present invention achieves the above objectives through the following technical solutions: A down slugging and sorting device for down processing includes a sorting box with an open top and circular openings on the side walls. A disc with a hole number one is rotatably mounted at the circular opening. The sorting box is provided with a drive mechanism for rotating the disc. A hollow roller is rotatably installed at the first hole. An air suction device is connected to one end of the roller located outside the sorting box. Several through holes are provided on the arc-shaped surface of the roller located inside the sorting box. A screen for sorting down is provided at the through holes. The roller is equipped with a grouping mechanism for stirring down.

[0008] Preferably, the sorting mechanism includes a collar movably sleeved on the roller, a plurality of blades for sorting down are fixedly provided on the collar, and a power mechanism for driving the collar to move and rotate on the roller. The roller surface is provided with a threaded groove, and the collar is provided with a limiting block located in the threaded groove for controlling the position of the collar.

[0009] Preferably, the blade has several through holes in the middle for the down to pass through.

[0010] Preferably, the blade is equipped with a vibration motor for driving the blade to vibrate.

[0011] Preferably, the power mechanism includes a primary motor fixedly disposed inside the collar, and the output shaft end of the primary motor is concentrically fixedly connected to a roller that contacts the surface of the roller.

[0012] Preferably, the No. 1 motor is a dual-head motor, and both output shafts of the No. 1 motor are fixedly connected to drive wheels. A rotating shaft parallel to its axis is rotatably mounted on the collar. A driven wheel that contacts the drive wheel is fixed at one end of the rotating shaft inside the collar. The drive wheel drives the driven wheel to rotate through friction. A brush roller for cleaning the screen is concentrically fixed at one end of the rotating shaft outside the collar.

[0013] Preferably, the roller is provided with a plurality of sliding grooves corresponding one-to-one with the screen, and a baffle plate for blocking the screen is slidably installed at the sliding groove; The roller is equipped with a power component for moving the cover plate.

[0014] Preferably, the power component is an electromagnet.

[0015] Preferably, the driving mechanism includes a second motor and a reducer fixed on the sorting box, and the output end of the reducer is connected to the disc.

[0016] Preferably, a first gear is fixedly connected to the sorting box, and a second gear that meshes with the first gear is fixedly sleeved on the roller.

[0017] The beneficial effects of this invention are as follows: This invention uses a roller that generates a suction effect to move within a pile of down feathers, utilizing the principle of a vacuum cleaner to specifically extract small down feathers. Compared to the traditional airflow sorting method, it has lower operational difficulty, requires less equipment investment, has a faster production speed, and higher down sorting efficiency. At the same time, it can simultaneously handle down clumping and sorting, reducing processes and further improving production efficiency. Attached Figure Description

[0020] The present application will now be described in further detail. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example 1 like Figure 1-5 As shown, a down sorting and sizing device for down processing includes a rectangular sorting box 2. The top of the sorting box 2 is open, and one of its longitudinal side walls has a circular opening 1. A disc 4 with a hole 3 is rotatably mounted at the circular opening 1, and the hole 3 is located at a non-central position on the disc 4. A discharge port is provided on the other longitudinal side wall of the sorting box 2, and a detachable baffle 25 is provided at the discharge port. The baffle 25 can be made of plastic for easy removal and detachment. After removing the baffle 25, the sorted down can be taken out for processing the next batch of down.

[0022] The sorting box 2 is equipped with a drive mechanism for rotating the disc 4. Preferably, the drive mechanism includes a second motor 21 and a reducer 22. The reducer 22 is fixedly mounted on the sorting box 2 via a bracket 26, and the second motor 21 is connected to the input end of the reducer 22. The output end of the reducer 22 is concentrically fixedly connected to the disc 4. Driven by the reducer 22, the disc 4 can rotate at the circular opening 1 at a speed of 5-10 rpm.

[0023] A hollow roller 5 is rotatably mounted at hole 3. An air suction device is connected to one end of roller 5 located outside the sorting box 2. Since roller 5 is movable, a flexible hose or plastic film can be used for connection. Preferably, a high-pressure suction fan can be used, which has both blowing and suction functions; the suction function of this device is used here. Several through holes 6 are provided on the arc-shaped surface of roller 5 inside the sorting box 2, connecting the outside of roller 5 to its inner cavity. A screen 7 for sorting down is fixed at each of the through holes 6.

[0024] The roller 5 is equipped with a grouping mechanism for stirring down.

[0025] It should be noted that the dried down is poured directly into sorting box 2, and then the drive mechanism and suction equipment are started simultaneously. Motor 21 drives disc 4 to rotate via reducer 22, causing roller 5 to rotate around the axis of disc 4. Because support 26 is located on the rotation trajectory of roller 5, the hose on roller 5 will collide with support 26 during rotation. Trigger switches can be installed on both sides of support 26. When roller 5 rotates to the position of support 26 and contacts the trigger switch, motor 21 is reversed under the control of the controller (existing technology). The controller here is connected to motor 21 and trigger switches.

[0026] As roller 5 rotates, the suction device continuously generates air, creating an inward airflow at the through-hole 6 of roller 5. This airflow acts on the down feathers, drawing them towards the screen 7. The size of the passing down feathers is controlled by the aperture of the screen 7, allowing for direct sorting of high-quality small down feathers. The sucked-in small down feathers can be collected within a flexible hose (similar to the principle of a vacuum cleaner, which will not be elaborated further).

[0027] At the same time, as the roller 5 rotates inside the sorting box 2, it drives the grouping mechanism to move. The grouping mechanism can break up the clumps and clusters in the down, making it easier for the roller 5 to sort them.

[0028] Furthermore, a first gear 23 is fixedly connected to the bracket 26, and the axis of the first gear 23 coincides with the axis of the disk 4. The first gear 23 has a central hole, through which the output shaft of the reducer 22 passes and connects to the disk 4. A second gear 24, which meshes with the first gear 23, is fixedly sleeved on the roller 5. When the roller 5 rotates around the axis of the disk 4, the second gear 24 rotates relative to the first gear 23, thereby causing the roller 5 to rotate. When the roller 5 rotates, it drives the sorting mechanism to rotate synchronously within the sorting box 2, improving the sorting efficiency of the sorting mechanism.

[0029] Preferably, the down-separating mechanism in this embodiment includes a collar 8 movably sleeved on the roller 5, and a plurality of blades 9 for separating down into groups are fixedly provided on the collar 8 along its circumference. The collar 8 is provided with a power mechanism for moving and rotating the collar 8 on the roller 5.

[0030] The roller 5 has a threaded groove 10 on its surface, and the collar 8 has a limiting block 11 located in the threaded groove 10 to control the position of the collar 8.

[0031] It should be noted that multiple sub-grouping mechanisms can be set. When a single sub-grouping mechanism is running, the power mechanism drives the collar 8 to rotate on the surface of the roller 5. Since a limiting block 11 is fixed inside the collar 8, the limiting block 11 slides in the threaded groove 10 during the rotation of the collar 8, so that the collar 8 can move along the length direction of the roller 5 and rotate along the axis of the roller 5.

[0032] When the collar 8 rotates, it drives the paddle 9 to beat the down in the sorting box 2, breaking up the down clumps. The collar 8 moves along the roller 5, allowing it to move to any position on the roller 5. Preferably, the bottom cross-section of the sorting box 2 is circular, so that the paddle 9 can contact all the down in the sorting box 2 during rotation, thereby enabling the paddle 9 to achieve all-round, thorough sorting of the down in the sorting box 2.

[0033] Preferably, in this embodiment, the blade 9 has several through holes 12 in its middle for down to pass through. The through holes 12 can be circular with a diameter of 2-4 cm, allowing down to pass through normally, while larger clumps of down cannot pass through the through holes 12. The through holes 12 prevent the blade 9 from carrying too much down due to its large cross-sectional area, thus affecting the clumping effect of the blade 9. Small clumps are broken up when they collide with the blade 9 or during the splitting process of down at the multiple through holes 12. At the same time, a vibration motor is provided on the blade 9 to drive the blade 9 to vibrate.

[0034] It should be noted that the vibration motor drives the blade 9 to vibrate. When a large agglomerate is intercepted at the through hole 12, the vibration generated by the blade 9 can act on the agglomerate, causing the agglomerate to gradually become a smaller agglomerate. After multiple diversions, the small agglomerate becomes dispersed down, which is convenient for subsequent sorting.

[0035] Preferably, the power mechanism in this embodiment includes a primary motor 13 fixedly disposed inside the collar 8, and a roller 14 concentrically fixedly connected to the output shaft end of the primary motor 13, which contacts the surface of the roller 5. The roller 14 uses an inflatable rubber tire, and maintains a large frictional force when in contact with the roller 5, which can produce slight deformation. When the roller 14 moves to the screen 7, it can still move normally. To ensure the roller 14 can pass through normally, the screen 7 is made of metal to guarantee its strength.

[0036] Furthermore, the aforementioned No. 1 motor 13 is a dual-head motor with two output shafts rotating in the same direction. Both output shafts of the No. 1 motor 13 are fixedly connected to a drive wheel 15, which is parallel and concentrically arranged with the roller 14. A rotating shaft 16 parallel to its axis is rotatably mounted on the collar 8. One end of the rotating shaft 16, located inside the collar 8, is fixedly connected to a driven wheel 17 that contacts the drive wheel 15. The drive wheel 15 drives the driven wheel 17 to rotate through friction. A brush roller 18 for cleaning the screen 7 is concentrically fixedly connected to the other end of the rotating shaft 16, located outside the collar 8.

[0037] It should be noted that because down contains a large number of feather shafts, many feather shafts will get stuck into the screen 7 during the sorting process, or be adsorbed onto the surface of the screen 7 by the airflow, thus affecting the normal use of the screen 7. Furthermore, because the loop 8 moves laterally, its edge exerts a lateral shearing force on the feather shafts when in contact with them on the surface of the screen 7, causing the feather shafts to be cut off. At the same time, the presence of feather shafts will also hinder the movement of the loop 8.

[0038] With a driving wheel 15 and a driven wheel 17, when the first motor 13 drives the roller 14 to rotate, it synchronously drives the driving wheel 15 to rotate. The rotating wheel drives the driven wheel 17 to rotate through friction. The driven wheel 17 drives the brush roller 18 to rotate through the rotating shaft 16, which drives the feathers at the screen 7 to move away from the screen 7, making it easier for the feathers to detach from the screen 7.

[0039] In this embodiment, the roller 5 is provided with a plurality of grooves corresponding one-to-one with the screen 7, and a cover plate 19 for blocking the screen 7 is slidably installed at the groove. The cover plate 19 is made of iron material.

[0040] The roller 5 is equipped with a power component 20 for moving the baffle 19. Preferably, the power component 20 is an electromagnet.

[0041] It should be noted that because the roller 5 is relatively long, the airflow intensity at each through hole 6 is different, which may result in poor airflow at the through hole 6 at the end far from the air intake device, thus affecting the sorting efficiency of down.

[0042] An electromagnet is installed, which activates when it moves to the cover plate 19, generating a strong magnetic force on the cover plate 19. When the collar 8 drives the electromagnet to rotate, it synchronously drives the cover plate 19 to slide within the groove, ultimately covering the screen 7. Because the cover plate 19 moves inside the collar 8, the brush roller 18 has already cleaned the screen 7, preventing feathers from obstructing its movement.

[0043] By controlling the baffle 19, the suction position on the roller 5 can be controlled, so that the roller 5 can fully and powerfully suck up the small down feathers in the sorting box 2, ensuring the sorting efficiency.

[0044] In the above embodiments, the No. 1 motor 13, the vibration motor, and the electromagnet can be powered by a storage battery, preferably a lithium battery.

[0045] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
