Description

Technical Field

[0001] This utility model relates to the field of down product manufacturing equipment, and in particular to a dust-collecting type down removal device for down products. Background Technology

[0002] Down comforters, down pillows, and other down bedding products will attract fine lint and feathers after being filled with down. These need to be cleaned before packaging and selling. Previously, a soft brush was used to brush the lint and feathers on both sides, causing them to fly up in the removal chamber and then be sucked out by a negative pressure lint collection device. However, lint and feathers that were not sucked out in time would fall back onto the surface of the down products, resulting in unsatisfactory removal results. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a dust suction type down product removal device. In a relatively enclosed removal chamber, a tornado-style air knife blows high-pressure air onto the top and bottom of the down product. A strong air shock wave is generated by a high-speed rotating jet structure, causing the down lint and dust on the surface of the down product to continuously float in the cavity. Then, a negative pressure suction collection device collects and removes the lint and dust, which is very effective.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A dust-collecting and feather-removing device for down products includes a material conveying platform, a feather removal and cleaning device, and a negative pressure feather collection device. Linear modules are mounted on both sides of the material conveying platform, and a sliding rod is connected between the sliding tables of the two linear modules. A gripper is installed on the front side of the sliding rod, which is driven to move back and forth between the beginning and end of the material conveying platform. The feather removal and cleaning device is located at the beginning of the material conveying platform and includes a support frame forming a receiving cavity. Curtains are installed at the front and rear ends of the support frame, and the other sides are sealed to form a feather removal cavity through which the down products pass. A feather removal mechanism is installed inside the feather removal cavity, and the cavity's pipes are connected to the negative pressure feather collection device. The feather removal mechanism includes a row of tornado-shaped air knives horizontally positioned above and below the height of the sliding rod, and the air knife pipes are connected to a high-pressure air supply source.

[0005] A further improvement is that the upper row of tornado air knives is tilted downwards at a 30-degree angle towards the incoming material, and the lower row of tornado air knives is tilted upwards at a 30-degree angle towards the incoming material. The front end of the tornado air knives is 10cm away from the down product, the flow rate is 160L / min, and the distance between adjacent tornado air knives in each row is no more than 15cm.

[0006] A further improvement is to arrange the tornado air knives in the hair removal chamber at intervals on the horizontal support, with a main air pipe behind the horizontal support. Branch lines are opened on the main air pipe to connect to each tornado air knife, and the end of the main air pipe is connected to a high-pressure air supply source.

[0007] A further improvement is to connect electromagnetic control valves to the air inlet branches of each tornado blade, allowing for precise flow control.

[0008] A further improvement involves adding a suction chamber on each side of the feather removal chamber. Each suction chamber is connected to a negative pressure feather collection device. The inner walls of the suction chambers are connected to the upper and lower chambers of the feather removal chamber, which are separated by the down product. The grippers pull the down product forward, dividing the feather removal chamber into upper and lower chambers, each connected to the negative pressure feather collection device, resulting in better feather collection.

[0009] A further improvement is to arrange at least three grippers in a row at intervals. This makes pulling down products more stable.

[0010] A further improvement is to connect the top end of the material conveyor to the feed platform, which is level with the top surface. This facilitates the feeding operation. Beneficial effects

[0011] Down products are pulled by grippers from the front to the rear of the conveyor table. When passing through the de-feathering chamber, the tornado air knife inside the de-feathering cleaning device blows air at high pressure on the top and bottom of the down products. The high-speed rotating jet structure generates a strong air shock wave, causing the down lint and dust on the surface of the down products to float continuously in the cavity. Then, the negative pressure suction and collection device collects and removes them. After being pulled out of the de-feathering chamber, the surface of the down products is completely free of dust and lint, with excellent results. Attached Figure Description

Linear modules 11 are mounted on both sides of the conveying platform 1, and a sliding rod 12 is connected between the slides of the two linear modules 11. A row of grippers 13 is installed at intervals on the front side of the sliding rod 12. The sliding rod 12 is driven to move back and forth between the head and tail ends of the conveying platform 1. The feather removal and cleaning device 2 is located at the head end of the conveying platform 1 and includes a support 21 forming a receiving cavity. Curtains 22 are provided at the front and rear ends of the support 21, and the other surfaces are sealed to form a feather removal cavity 2 through which down products pass. A feather removal mechanism is installed inside the feather removal cavity. The feather removal mechanism includes horizontally positioned above and below the height of the sliding rod. A row of tornado air knives 24 is provided, with the tornado air knives spaced on the horizontal support 25. The upper row of tornado air knives 24 is inclined downward at a 30-degree angle towards the incoming material, and the lower row of tornado air knives is inclined upward at a 30-degree angle towards the incoming material. The front end of the tornado air knives is 10cm away from the down product, and the flow rate is 160L / min. The distance between adjacent tornado air knives in each row is no more than 15cm. A main air pipe 26 is provided behind the horizontal support 25. Branch lines are opened on the main air pipe and connected to electromagnetic control valves 27 one by one, which are then connected to each tornado air knife 24. The end of the main air pipe is connected to a high-pressure air supply source. A dust collection chamber 28 is provided on each side of the hair removal chamber (23). The left and right dust collection chambers 28 are respectively connected to a negative pressure hair collection device 3. The inner walls of the left and right dust collection chambers are respectively connected to the upper and lower chambers of the hair removal chamber separated by the down product.

[0014] The down product is laid flat at the front end and fed to the gripper gripping position. The gripper opens and tightens, pulling the down product from the front end of the conveyor table to the rear end. When passing through the de-feathering chamber, the tornado air knife inside the de-feathering cleaning device blows air at high pressure on the top and bottom of the down product. The high-speed rotating jet structure generates a strong air shock wave, causing the down lint and dust on the surface of the down product to continuously float in the cavity. Then, the negative pressure suction and collection device collects and removes them. After being pulled out of the de-feathering chamber, the surface of the down product is completely free of dust and lint, with excellent results.
