[0001] The utility model belongs to down processing equipment technical field, especially, relate to a gradient density down sorting device. BACKGROUND

[0002] Down is a kind of natural warm-keeping material, because its light, fluffy, warm-keeping strong and other excellent characteristics, is widely used in down jacket, down quilt, down pillow and other home textile and clothing products, with the rapid development of global textile industry and the pursuit of high-quality life of consumer, the demand of market to down raw material is increasing year by year, and higher requirements are put forward to the grading precision and processing efficiency of down.

[0003] However, the existing down sorting device still has many problems, on the one hand, the existing equipment mostly adopts single-layer sieve plate or plane type multilayer sieve plate design, and the single-layer sieve plate can only complete simple screening, and cannot realize fine grading of different density down, and the plane type multilayer sieve plate is prone to accumulation and blockage due to poor flowability of down, resulting in low sorting efficiency, on the other hand, down is prone to clumping due to static electricity, humidity and other factors during collection and storage, and the existing equipment lacks effective feed pre-dispersion mechanism, and when the clumped down directly enters the screening process, different density down is wrapped with each other, cannot be normally graded through the sieve plate, not only causes waste of high-quality down, but also blocks the sieve hole, increases equipment maintenance cost.

[0004] Therefore, we provide a gradient density down sorting device to solve the above problems. Utility model content

[0005] The utility model aims at providing a gradient density down sorting device, which solves the problems of low sorting efficiency, easy blockage and lack of pre-dispersion mechanism of the existing down sorting device by the cooperation of screening mechanism and dispersion mechanism.

[0006] To solve the above technical problems, the utility model is realized by the following technical schemes.

[0007] This utility model relates to a gradient density down sorting device, comprising a housing, a screening mechanism fixedly connected to the rear side of the housing, and a dispersing mechanism fixedly connected to the top of the housing. The screening mechanism includes a dual-axis motor, the front side of which is fixedly connected to the housing. Both output ends of the dual-axis motor are fixedly connected to a driving bevel gear. A driven bevel gear meshes with one side of the driving bevel gear. A worm gear is fixedly connected to the front side of the driven bevel gear. A worm wheel meshes with the bottom of one side of the worm gear. One side of the worm wheel is rotatably connected to the housing, and a cam is fixedly connected to the other side of the worm wheel. The bottom of the cam... A sliding frame is provided, with its top slidably connected to the box body. A spring is installed at the bottom of the frame, and its bottom is fixedly connected to the box body. A sieve plate is slidably connected to the inner cavity of the frame. A movable door is hinged to the front of the box body, allowing workers to open the door and remove materials from the sieve plate. The surfaces of the dual-shaft motor and other transmission components are all covered with protective shells, one side of which is fixedly connected to the box body. This effectively isolates external dust, down fibers, and other impurities from entering the transmission components, preventing problems such as transmission jamming and accelerated wear caused by impurities adhering to the components. There are multiple springs, symmetrically distributed on both sides of the frame.

[0008] The present invention is further configured such that the dispersing mechanism includes a feed pipe, the bottom of which is fixedly connected to the housing, a drive motor is fixedly connected to one side of the feed pipe, a first dispersing roller is fixedly connected to the output end of the drive motor, a drive gear is fixedly connected to the other side of the first dispersing roller, a driven gear meshes with the other side of the drive gear, a second dispersing roller is fixedly connected to one side of the driven gear, and the other side of the second dispersing roller is rotatably connected to the feed pipe. Dispersing rods are fixedly connected to the surfaces of both the first and second dispersing rollers, and the dispersing rods are staggered on the first and second dispersing rollers. Silicone scrapers are installed at the ends of the dispersing rods, which can reduce hard damage to the down fibers while enhancing the friction of contact with the down.

[0009] The present invention is further configured such that an inclined plate is provided at the bottom of the sieve plate, and one side of the inclined plate is fixedly connected to the box body. The inclined plate can transport the impurities falling from the sieve plate to the side of the movable door so that the staff can handle the impurities.

[0010] The present invention is further configured such that a limiting rod is provided in the inner cavity of the spring, the top of the limiting rod is fixedly connected to the plate frame, and the bottom of the limiting rod is slidably connected to the box body. The limiting rod can prevent the spring from shifting laterally or twisting during the extension and retraction process, and ensure that the spring always extends and retracts stably along the axial direction.

[0011] The present invention is further configured such that a guide plate is provided on the top of the second dispersing roller, and one side of the guide plate is fixedly connected to the feed pipe. The guide plate can accurately guide the down entering the feed pipe to the working area between the first dispersing roller and the second dispersing roller, so as to prevent the down from leaking from both sides of the roller body due to the deviation of the flow path.

[0012] The present invention is further configured such that limiting grooves are provided on both sides of the inner cavity of the plate frame, and both sides of the screen plate are slidably connected to the limiting grooves. The limiting grooves allow the screen plate to be completely pulled out from the inner cavity of the plate frame, so that workers can collect the material on the screen plate or replace the screen plate.

[0013] The present invention is further provided with a friction pad in the inner cavity of the limiting groove. One side of the friction pad is fixedly connected to the plate frame. The friction pad can increase the friction between the screen plate and the plate frame, and prevent the screen plate from shifting and sliding out of the inner cavity of the plate frame during the screening process.

The other side of the slider is fixedly connected to the plate frame. The slider and the sliding groove provide precise guidance and positioning for the plate frame.

[0015] The present invention has the following beneficial effects.

[0016] 1. The three-layer inclined screen plate design in this utility model achieves gradient sorting through different apertures, solving the problem that single-layer screen plates can only perform simple screening and cannot perform fine grading. It can accurately separate down of different densities. The inclined structure, combined with the cam-driven vibration mechanism, enhances the flowability of down by utilizing the dual effects of gravity and vibration, avoiding the accumulation and blockage caused by poor flowability of flat screen plates, and greatly improving sorting efficiency. The dual-axis motor drives the cam to rotate through bevel gear and worm gear transmission. Combined with spring reset, it enables the plate frame to drive the screen plate to generate stable and regular vibration, ensuring that the down is evenly distributed on the screen surface and fully screened, further improving the sorting accuracy.

[0017] 2. In the dispersing mechanism of this utility model, the drive motor drives the first dispersing roller to rotate. Through the meshing transmission of the active gear and the driven gear, the second dispersing roller rotates synchronously in opposite directions. The two rollers work together to form a shearing and tearing effect on the down entering the feed pipe, which can effectively disperse the down clumps that are stuck together due to static electricity, humidity and other factors. This solves the problem that the existing equipment lacks a pre-dispersing mechanism, causing the clumps of down to enter the screening process. Attached Figure Description

The dispersed down falls onto the sieve plate 209. Simultaneously, the dual-shaft motor 201 is started, driving the drive bevel gear 202 to rotate. The drive bevel gear 202 then... The driven bevel gear 203 rotates, which drives the worm gear 204 to rotate. The worm gear 204 drives the worm wheel 205 to rotate, and the worm wheel 205 drives the cam 206 to rotate and press the plate frame 207. When the plate frame 207 is pressed, it moves downward and compresses the spring 208. The sieve plate 209 moves with the plate frame 207. After the cam 206 disengages from the plate frame 207, the spring 208 extends and drives the plate frame 207 to reset, and reciprocating vibration occurs. After screening, the down feathers stay on the corresponding sieve plate 209 according to size. The staff can then remove the sieve plate 209 to collect them.
