Technical Field
[0001] This utility model relates to the field of down processing technology, specifically a processing device for water-repellent down. Background Technology
[0002] Down is lightweight and has excellent warmth retention, making it widely used in clothing, bedding, and other products. To enhance its practicality, down is often treated with a water-repellent process, giving it a certain degree of water resistance.
[0003] Currently, the processing of water-repellent down typically involves multiple independent steps, requiring multiple machines to perform pretreatment, water-repellent agent spraying, and drying, resulting in poor processing continuity and low efficiency. In particular, the water-repellent agent spraying stage is prone to uneven distribution, affecting the water-repellent effect of the down. Utility Model Content
[0004] The purpose of this invention is to provide a processing device for water-repellent down to solve the problems mentioned in the background art.
[0005] The technical solution of this utility model is: a processing device for water-repellent down, including two support frames, a first conveyor belt and a second conveyor belt installed between the two support frames, the first conveyor belt being located above the second conveyor belt, a collection box being provided below the second conveyor belt, a suction component communicating with the collection box being installed on the outside of the support frames, and a spraying mechanism being connected to the output end of the suction component being provided above the first conveyor belt and the second conveyor belt.
[0006] The effects achieved by the above components are as follows: the support frame supports and fixes the first and second conveyor belts, so that the first conveyor belt is located above the second conveyor belt, forming an upper and lower layered structure. The down can be processed during the conveying process of the first conveyor belt. The suction component draws the treatment agent in the collection box to the spraying mechanism for water-repellent treatment, and then it falls onto the second conveyor belt for further treatment, realizing the purpose of continuous processing of water-repellent down and increasing processing efficiency. Since the second conveyor belt is in the opposite direction to the first conveyor belt, it can flip the down falling onto the second conveyor belt for conveying, so that the down has a higher degree of contact with the sprayed water-repellent agent during the conveying process. At the same time, the collection box under the second conveyor belt can collect the excess water-repellent agent that drips down. The collection box is connected to the spraying mechanism through the suction component to realize the purpose of recycling the water-repellent agent and improve the utilization rate of the water-repellent agent.
[0007] Preferably, the suction assembly includes a suction pump fixed to one side of the support frame, the inlet of the suction pump is connected to a return pipe extending into the collection box, and the outlet of the suction pump is fixed to an output pipe connected to the spraying mechanism.
[0008] The effect achieved by the above components is as follows: the suction pump in the suction assembly provides power, the return pipe introduces the water-repellent agent in the collection box into the suction pump, and then delivers it to the spraying mechanism through the output pipe, thereby achieving the purpose of efficient recycling of the water-repellent agent and improving resource utilization.
[0009] Preferably, the spraying mechanism includes a horizontal pipe connected to the output pipe, with spray pipes evenly distributed on one side of the horizontal pipe, and multiple spray heads connected to the bottom of the spray pipes.
[0010] The effect achieved by the above components is as follows: the output pipe delivers the water-repellent agent to the horizontal pipe, the agent in the horizontal pipe is evenly distributed to each spray pipe, and multiple spray heads spray simultaneously, so that the agent can cover the down on the first and second conveyor belts, achieving the purpose of uniform spraying of the water-repellent agent and improving the uniformity of the water-repellent treatment of the down.
[0011] Preferably, a feeding plate mounted on the support frame is provided above the feeding end of the first conveyor belt, and a discharging plate mounted on the support frame is provided on one side of the discharging end of the second conveyor belt.
[0012] The effect achieved by the above components is as follows: the feeding plate installed on the support frame is located above the feeding end of the first conveyor belt, which facilitates the guidance of down onto the first conveyor belt; the unloading plate installed on the support frame is located on the discharge end side of the second conveyor belt, which facilitates the discharge of the processed down.
[0013] Preferably, a material guiding assembly is provided on one side of the feeding plate. The material guiding assembly includes a rotating roller rotatably mounted on the support frame. Two sets of symmetrical spiral protrusions are installed on the outer wall of the rotating roller. A pulley assembly is connected between the rotating roller and the rotating end of the first conveyor belt.
[0014] The effect achieved by the above components is as follows: when the first conveyor belt rotates, the pulley assembly drives the rotating roller to rotate synchronously. The down enters from the feed plate below the rotating roller. During the rotation of the spiral protrusion, the down is dispersed to both sides and evenly distributed on the first conveyor belt, thus achieving the purpose of uniform distribution of down on the first conveyor belt and improving the uniformity of subsequent spraying treatment.
[0015] This utility model provides an improved processing device for water-repellent down, which has the following improvements and advantages compared with the prior art:
[0016] Firstly, this invention uses a suction component to pump the treatment agent from the collection box to the spraying mechanism for spraying the water-repellent treatment agent. The down falls from the first conveyor belt onto the second conveyor belt for continuous conveying and spraying treatment, thus achieving the purpose of continuous processing of water-repellent down and increasing processing efficiency. Since the second conveyor belt is in the opposite direction to the first conveyor belt, it can flip the down falling onto the second conveyor belt for conveying, thereby increasing the complete contact between the down and the sprayed water-repellent agent during the conveying process.
[0017] Secondly, this utility model uses a suction pump in the suction assembly to provide power, and the return pipe guides the water-repellent agent in the collection box into the suction pump, and then delivers it to the spraying mechanism through the output pipe, thereby achieving the purpose of efficient recycling of the water-repellent agent and improving resource utilization.

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0024] This utility model provides an improved processing device for water-repellent down. The technical solution of this utility model is as follows:
[0025] In embodiments of this utility model, such as Figures 1-2As shown, a processing device for water-repellent down includes two support frames 1, with a first conveyor belt 2 and a second conveyor belt 3 installed between the two support frames 1. A loading plate 7 mounted on the support frame 1 is disposed above the inlet end of the first conveyor belt 2, and a unloading plate 9 mounted on the support frame 1 is disposed on one side of the outlet end of the second conveyor belt 3. The loading plate 7 mounted on the support frame 1 is located above the inlet end of the first conveyor belt 2 to facilitate guiding the down onto the first conveyor belt 2, while the unloading plate 9 mounted on the support frame 1 is located on the outlet end side of the second conveyor belt 3 to facilitate discharging the processed down. A material guiding assembly 8 is provided on one side of the feeding plate 7. The material guiding assembly 8 includes a rotating roller 81 rotatably mounted on the support frame 1. Two sets of symmetrical spiral protrusions 82 are installed on the outer wall of the rotating roller 81. A belt pulley assembly is connected between the rotating roller 81 and the rotating end of the first conveyor belt 2. When the first conveyor belt 2 rotates, the belt pulley assembly drives the rotating roller 81 to rotate synchronously. Down enters from the feeding plate 7 below the rotating roller 81. During the rotation of the spiral protrusions 82, the down is scattered to both sides and evenly distributed on the first conveyor belt 2, thus achieving the purpose of evenly distributing the down on the first conveyor belt 2.
[0026] The first conveyor belt 2 is located above the second conveyor belt 3. Since the second conveyor belt 3 and the first conveyor belt 2 have opposite conveying directions, the down falling onto the second conveyor belt 3 can be flipped and conveyed, increasing the complete contact between the down and the sprayed water-repellent agent during the conveying process. A collection box 4 is provided below the second conveyor belt 3. A suction assembly 5 connected to the collection box 4 is installed on the outside of the support frame 1. The output end of the suction assembly 5 is connected to a spraying mechanism 6 located above the first conveyor belt 2 and the second conveyor belt 3. The suction assembly 5 includes a suction pump 51 fixed to one side of the support frame 1. The inlet of the suction pump 51 is connected to... The return pipe 52 extends into the collection box 4. The outlet of the suction pump 51 is fixed with an output pipe 53 connected to the spraying mechanism 6. The suction pump 51 in the suction assembly 5 provides power. The return pipe 52 guides the water-repellent agent in the collection box 4 into the suction pump 51, and then delivers it to the spraying mechanism 6 through the output pipe 53. This achieves the purpose of efficient recycling of the water-repellent agent. The spraying mechanism 6 includes a horizontal pipe connected to the output pipe 53. Spray pipes are evenly distributed on one side of the horizontal pipe. Multiple spray heads are connected to the bottom of the spray pipes. The output pipe 53 delivers the water-repellent agent to the horizontal pipe. The agent in the horizontal pipe is evenly distributed to each spray pipe.
[0027] The working principle of the processing device for water-repellent down provided by this utility model is as follows: The feeding plate 7 installed on the support frame 1 is located above the feeding end of the first conveyor belt 2, which facilitates the guidance of down onto the first conveyor belt 2. The down can be processed during the conveying process of the first conveyor belt 2. The suction component 5 draws the treatment agent in the collection box 4 to the spraying mechanism 6 for water-repellent treatment agent spraying, and then it falls onto the second conveyor belt 3 for further processing, thus achieving the purpose of continuous processing of water-repellent down. Since the second conveyor belt 3 is in the opposite conveying direction to the first conveyor belt 2, it can flip the down falling onto the second conveyor belt 3 for conveying, so that the down has a higher degree of contact with the sprayed water-repellent agent during the conveying process. At the same time, the collection box 4 under the second conveyor belt 3 can collect the excess water-repellent treatment agent that drips down. The collection box 4 is connected to the spraying mechanism 6 through the suction component 5 to achieve the purpose of recycling the water-repellent treatment agent.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
