Abstract
Description
Technical Field
[0001] This utility model relates to the field of down processing technology, specifically to a degreasing device for down processing. Background Technology
[0002] Before processing down, it is necessary to remove the grease from the down. Generally, the first step in degreasing down is to soak the down in a degreasing agent to absorb and remove most of the grease from the surface of the down. After that, the washed and degreased down is placed under an extruder for mechanical degreasing.
[0003] The patent document with authorization announcement number CN113322615B discloses a thin-layer kneading down processing mechanical degreasing device. The device uses a rolling component to perform rolling mechanical degreasing treatment on the down falling from the conveying component. It mainly drives the first rolling plate and the second rolling plate to reciprocate, thereby mechanically squeezing the down on the conveyor belt. The rolling component has a complex structure and cannot continuously squeeze the down on the conveyor belt.
[0004] Patent document CN218539888U discloses a down degreasing device. This device uses a support plate mounted on the upper surface of a turntable. When under pressure, the support plate is compressed by a compression mechanism. The degreasing tank is monitored through a viewing window outside the mixing tank as down is added and compressed. The operator then determines the required amount of degreasing agent by the depth of compression. This simple, fast, and convenient method improves the accuracy and speed of down degreasing. However, this device primarily uses water washing to degrease down, which requires a large amount of water and is unsuitable for large-scale down degreasing. Utility Model Content
[0005] The main purpose of this invention is to provide a degreasing device for down processing that can mechanically squeeze down after washing and degreasing, squeeze out the oil that has not been completely washed away from the down, and thus reduce the amount of water used.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A degreasing device for down processing includes two symmetrically arranged side plates, a conveyor belt installed between the two side plates, a support plate between the upper and lower parts of the conveyor belt, the support plate being fixedly connected to the two side plates, the upper end of the support plate contacting the upper and lower ends of the conveyor belt, a gathering and flattening device being arranged between the two side plates above the conveyor belt, and a roller pressing device being arranged between the two side plates on one side of the gathering and flattening device; the gathering and flattening device includes two gathering plates, the lower end of the gathering plates slidingly contacting the upper end of the conveyor belt, the two gathering plates being fixedly connected to the two side plates respectively, the gathering plates including an inclined part and a straight part, the straight part being close to the roller pressing device, the end of the inclined part away from the straight part being close to the side plate, the straight parts of the two gathering plates being rotatably connected by a rotating roller, a second motor being fixed on the straight part of any one of the gathering plates, the output shaft of the second motor being concentrically fixedly connected to the rotating roller, and multiple levers being fixed on the outer edge of the rotating roller.
[0008] Specifically, a fixing rod is fixed on the straight part of the gathering plate, and the fixing rod is fixedly connected to the side plate.
[0009] Specifically, the axial direction of the lever is parallel to the radial direction of the roller.
[0010] Specifically, the roller pressing device includes multiple roller pressing units, which are evenly distributed along the upper movement direction of the conveyor belt. Each roller pressing unit includes a pressure roller, and a slider is rotatably connected to the rotating shaft at both ends of the pressure roller. The slider has slots on both the left and right sides, and vertical slots corresponding to the sliders are opened on the side plates. The sliders are slidably disposed in the vertical slots, and the side plates on the left and right sides of the vertical slots are slidably engaged in the slots. A first motor is fixed on any slider, and the output shaft of the first motor is concentrically and fixedly connected to the rotating shaft of the pressure roller. A spring is fixed to the upper end of each slider, and the lower end of the spring is fixedly connected to the upper end of the slider. The upper end of the spring is fixedly connected to the side plate. Multiple guide rods are fixed to the upper end of the slider.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. By incorporating a gathering and flattening device, the down feathers are automatically gathered into long strips of uniform thickness during the conveying process. This avoids uneven down accumulation, ensures that pressure is applied evenly during subsequent degreasing operations, and improves the overall processing quality.
[0015] 2. The roller pressing device utilizes the speed difference between the pressure roller and the conveyor belt to generate a kneading motion. Combined with the cushioning design of springs and sliders, it effectively squeezes out residual grease from the down feathers. At the same time, the support plate provides stable support for the conveyor belt, preventing pressure loss and ensuring more thorough grease extraction.
[0016] 3. The installation of a lower pipe and nozzles automatically flushes the lower end of the conveyor belt, preventing down from adhering during operation, reducing clogging and maintenance needs. This extends the service life of the equipment and ensures smooth continuous production.
[0017] 4. This device integrates functions such as gathering, flattening, rolling, and cleaning, achieving a high degree of automation and reducing manual intervention. The down feathers are processed seamlessly from input to degreasing and discharge, optimizing the processing flow and improving production efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1: Refer to Figures 1-3 As shown, a degreasing device for down processing includes two side plates 1 arranged symmetrically front to back. A conveyor belt 3 is installed between the two side plates 1. A support plate 2 is provided between the upper and lower parts of the conveyor belt 3. The support plate 2 is fixedly connected to the two side plates 1. The upper end of the support plate 2 contacts the upper and lower ends of the conveyor belt 3. A gathering and flattening device is provided between the two side plates 1 above the conveyor belt 3. A roller pressing device is provided between the two side plates 1 on one side of the gathering and flattening device.
[0024] The gathering and flattening device includes two gathering plates 13, the lower end of which slides in contact with the upper end of the conveyor belt 3.
[0025] Two gathering plates 13 are fixedly connected to two side plates 1 respectively. The gathering plate 13 includes an inclined portion 132 and a straight portion 131. A fixing rod 133 is fixed on the straight portion 131 of the gathering plate 13, and the fixing rod 133 is fixedly connected to the side plate 1. The straight portion 131 is close to the roller pressing device, and the end of the inclined portion 132 away from the straight portion 131 is close to the side plate 1.
[0026] The straight portions 131 of the two gathering plates 13 are rotatably connected by a rotating roller 14. A second motor 15 is fixed on the straight portion 131 of any one of the gathering plates 13. The output shaft of the second motor 15 is concentrically fixed to the rotating roller 14. Multiple levers 16 are fixed on the outer edge of the rotating roller 14. The axial direction of the levers 16 is parallel to the radial direction of the rotating roller 14.
[0027] The roller pressing device includes multiple roller pressing units, which are evenly distributed along the movement direction of the upper part of the conveyor belt 3.
[0028] The roller pressing unit includes a pressure roller 7. Sliders 10 are rotatably connected to the rotating shafts at both ends of the pressure roller 7. Slots 11 are provided on both the left and right sides of the sliders 10. Vertical grooves 6 corresponding to the sliders 10 are provided on the side plates 1. The sliders 10 are slidably disposed in the vertical grooves 6. The side plates 1 on the left and right sides of the vertical grooves 6 are partially slidably engaged in the slots 11. A first motor 12 is fixed on any one of the sliders 10. The output shaft of the first motor 12 is concentrically and fixedly connected to the rotating shaft of the pressure roller 7. A spring 8 is fixed on the upper end of each slider 10. The lower end of the spring 8 is fixedly connected to the upper end of the slider 10. The upper end of the spring 8 is fixedly connected to the side plate 1. Multiple smooth rods 9 are fixed on the upper end of the sliders 10. The smooth rods 9 are vertically arranged and slidably connected to the side plates 1.
[0029] In this embodiment, the upper part of the conveyor belt 3 conveys from left to right, and the pressure roller 7 rotates counterclockwise. The rotation speed of the pressure roller 7 is less than the rotation speed of the conveyor belt 3.
[0030] Start the conveyor belt 3, the first motor 12, and the second motor 15. The down comforter, which has been washed and preliminarily dehydrated, is fed onto the upper end of the conveyor belt 3. As the conveyor belt 3 transports the down to the right, the down on the conveyor belt 3 is gathered together under the guidance of the inclined portions 132 of the two gathering plates 13. After passing between the straight portions 131 of the two gathering plates 13, the down on the conveyor belt 3 is transported to the right in a long strip.
[0031] As the long strips of down on conveyor belt 3 move to the area below roller 14, the roller 14 drives the lever 16 to rotate. The rotating lever 16 pushes excess down to spread to adjacent thinner areas, creating a uniform distribution effect similar to a "rake." The rotating lever 16 can move the long strips of thick down on conveyor belt 3 to thinner areas, thus ensuring a consistent thickness of the down strips on conveyor belt 3. Since the axial direction of the lever 16 is parallel to the radial direction of roller 14, the down that is moved by the lever 16 easily separates from the lever 16 when it reaches a thinner area, allowing the down adhering to the lever 16 to slide off.
[0032] An arc-shaped plate 17 is fixed between the straight portions 131 of the two gathering plates 13. The arc-shaped plate 17 is located above the rotating roller 14 and is concentric with the rotating roller 14. During the rotation of the rotating roller 14 and the lever 16, the down feathers propelled by the lever 16 are easily thrown upwards by the centrifugal force of the rotating roller 14 and the lever 16. In this embodiment, the arc-shaped plate 17 is provided to block the thrown down feathers and prevent down feathers from splashing.
[0033] When the long strips of down on the conveyor belt 3 move to the bottom of the pressure roller 7, the rotating pressure roller 7 can squeeze the down on the conveyor belt 3, thereby squeezing out the grease that has not been completely washed away from the down.
[0034] Since the upper and lower ends of the conveyor belt 3 are in contact with the upper end of the pallet 2, the pallet 2 can provide effective support for the upper part of the conveyor belt 3, which can ensure the squeezing force of the pressure roller 7 on the down on the conveyor belt 3.
[0035] Through the buffer design of spring 8 and slider 10, when the thickness of the down on conveyor belt 3 increases, the pressure roller 7 squeezes the down on conveyor belt 3, causing slider 10 to compress spring 8 and move upward, thus buffering the pressure roller 7 and preventing damage to it. Multiple guide rods 9 are slidably connected to side plate 1, which can improve the stability of slider 10 and pressure roller 7.
[0036] Because of the speed difference between the conveyor belt 3 and the pressure roller 7, when the down on the conveyor belt 3 passes under the pressure roller 7, the pressure roller 7 and the conveyor belt 3 can rub the down, thereby improving the extrusion efficiency of the oil that has not been completely washed away from the down.
[0037] After the down on conveyor belt 3 is squeezed and degreased, it is discharged from the right end of conveyor belt 3 as the conveyor belt 3 moves.
[0038] Example 2: Based on Example 1, referring to... Figure 1 As shown, a lower pipe 4 is fixed between the two side plates 1. The lower pipe 4 is located below the conveyor belt 3, and multiple nozzles 5 are fixedly connected to the side of the lower pipe 4 facing the conveyor belt 3.
[0039] Connect the lower pipe 4 to the outlet of the water pump and the inlet of the water pump to the water tank. After the water pump is started, the water in the water tank is pressurized by the water pump and sprayed out through the lower pipe 4 and the nozzle 5. The water sprayed from the nozzle 5 can wash the lower end of the conveyor belt 3, which can prevent down from sticking to the lower end of the conveyor belt 3.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
