Description

Technical Field

[0001] The present invention relates to the technical field of down processing equipment, and more particularly to a down cleaning device used for producing down protective pads. Background Art

[0002] Down is generally classified by source as goose down or duck down, and by color as white or gray. It grows on the bellies of geese and ducks. Down that appears reed-like is called down, while feathers appear in flakes. Down, as the name suggests, consists of feathers, which provide support and allow the down to rebound quickly. Down, on the other hand, is a three-dimensional spherical structure consisting of a core and numerous filaments radiating outward, similar to a dandelion. Down filaments are composed of thousands of tiny, hollow scales stacked together. Compared to fibers like cotton, silk, synthetic fibers, and wool, down maintains its loftiness for extended periods and offers superior warmth retention.

[0003] Because of down's warmth, softness, and comfort, down comforters are widely used in clothing, bedding, and other applications, such as down pads, to protect vital joints like the head, neck, shoulders, waist, elbows, and knees. Currently, down pads require cleaning during the production process to ensure cleanliness. However, existing down cleaning equipment often uses a drum-type system, which easily clumps the down and results in incomplete cleaning. Summary of the Invention

[0041] When the sleeve shaft 511 and the rotating drum 59 rotate respectively until the adjacent first scrubbing plate 512 and the second scrubbing plate 510 overlap, the interval between the first scrubbing plate 512 and the second scrubbing plate 510 in the axis direction of the sleeve shaft 511 is a scrubbing area, and the first scrubbing plate 512 and the second scrubbing plate 510 scrub the down to be cleaned in the scrubbing area by rubbing;

[0042] The scrubbing drive mechanism 4 is used to adjust the height of the scrubbing area. The scrubbing drive mechanism 4 includes a worm gear 44, a worm 45, a first cam 43, a first limiting ring 42, a second cam 46 and a second limiting ring 48. The output shaft of the driven gear 55 is fixedly connected to the worm 45, and the worm 45 is meshed with the worm gear 44. The output shaft of the worm gear 44 is fixedly connected to the first cam 43 at one end close to the sleeve shaft 511. The circumferential surface of the first cam 43 is in friction with the first limiting ring 42. The first limiting ring 42 is fixedly connected to the sleeve shaft 511, and the first limiting ring The first spring 41 is fixedly connected to the end of the worm gear 42 facing the driving gear 54, and the end of the first spring 41 away from the first limiting ring 42 is fixedly connected to the driving gear 54.

[0044] In the above embodiment, the down to be cleaned is put into the box body 1 through the feed port 13, and the second motor 51 located on the side of the base 3 away from the box body 1 is started. The second motor 51 drives the main shaft 52, and the limit pin fixedly connected to the side end of the main shaft 52 drives the transition shaft 53 to rotate, so that the driving gear 54 is meshed with the driven gear 55 for transmission, and the driven gear 55 is meshed with the gear ring 56 for transmission, wherein the rotation directions of the driving gear 54 and the gear ring 56 are opposite, for example, as Figure 5As shown, the rotation direction of the driving gear 54 is the direction indicated by the arrow, that is, it rotates counterclockwise, and the rotation direction of the driving gear 54 through the driven gear 55 to transmit the gear ring 56 is clockwise, that is, the rotation direction of the driving gear 54 and the gear ring 56 are opposite. In other embodiments, the rotation direction of the driving gear 54 can also be clockwise, which is not limited here. The transition shaft 53 drives the sleeve shaft 511 to rotate in a direction opposite to the direction of rotation of the gear ring 56 driving the rotating drum 59 through the guide column 58, thereby realizing that the first scrubbing plate 512 and the second scrubbing plate 510 rotate in opposite directions. Among them, along the radial direction of the worm gear 44, the convex portion of the first cam 43 and the convex portion of the second cam 46 are staggered, so that the transmission direction of the first cam 43 to the first limiting ring 42 is opposite to the transmission direction of the second cam 46 to the second limiting ring 48, so that the sleeve shaft 511 drives the first scrubbing plate 512 to rotate with the transition shaft 53 while also moving up and down along the axis of the transition shaft 53, and the rotating drum 59 drives the second scrubbing plate 510 to rotate around the axis of the transition shaft 53 with the guide column 58 while also moving up and down along the axis of the transition shaft 53, thereby realizing that the first scrubbing plate 512 and the second scrubbing plate 510 are stirred while also efficiently scrubbing the down located in the scrubbing area. Exemplarily, the end of the sleeve shaft 511 away from the first limiting ring 42 is slidably connected to the limiting shaft 513, and the end of the limiting shaft 513 away from the sleeve shaft 511 is fixedly connected to the box body 1, wherein the axis of the limiting shaft 513 is collinear with the rotation axis of the sleeve shaft 511 to ensure that the sleeve shaft 511 rotates stably with the transition shaft 53 and slides stably with the first limiting ring 42.

When the first scrubbing plates 512 and the adjacent second scrubbing plates 510 move toward each other along the axis of the sleeve shaft 511, the scrubbing protrusions on the surfaces of the first scrubbing plates 512 and the second scrubbing plates 510 rub against the down, thereby scrubbing the down located between the first scrubbing plates 512 and the second scrubbing plates 510. In other embodiments, the number of first scrubbing plates 512 and the number of second scrubbing plates 510 can be equal, which is not a limitation here.

The end of the baffle 12 away from the support seat 9 is slidably connected to the box body 1. The sliding direction of the baffle 12 and the box body 1 is parallel to the axis direction of the sleeve shaft 511, and the baffle 12 is used to control the opening of the feed port 13.

[0046] When the support seat 9 moves away from the box body 1 to the maximum displacement, the feed port 13 is opened, and the main shaft 52 and the transition shaft 53 are spaced apart;

[0047] When the support base 9 moves to the initial position in the direction close to the box body 1 , the feed port 13 is closed, and the main shaft 52 is slidably connected to the transition shaft 53 .

[0048] In the above embodiment, the driving assembly includes a hydraulic cylinder 11 and a telescopic rod 10. The hydraulic cylinder 11 is fixedly mounted on the box body 1. The output end of the hydraulic cylinder 11 is fixedly connected to the telescopic rod 10. The end of the telescopic rod 10 away from the hydraulic cylinder 11 is fixedly connected to the support seat 9. By starting the hydraulic cylinder 11 in the driving assembly, the hydraulic cylinder 11 drives the telescopic rod 10 to drive the support seat 9 to move to the maximum displacement in the direction away from the box body 1. The support seat 9 drives the baffle 12 to move synchronously in the direction away from the box body 1 to open the feed port 13. At this time, the down to be cleaned can be continuously transported to the box body 1 through the feeding pipe 8. Similarly, after the transportation is completed, it is only necessary to further start the hydraulic cylinder 11 so that the hydraulic cylinder 11 drives the telescopic rod 10 to drive the support seat 9 to move to the initial position in the direction close to the box body 1. The support seat 9 drives the baffle 12 to move synchronously in the direction close to the box body 1 to close the feed port 13, thereby preventing the down from running out of the box body 1 during the cleaning process and facilitating the scrubbing process of the down to be cleaned. In other embodiments, the driving assembly may be a cross lifting device, a screw lifting device, etc., which is not limited here.
