Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic product liquid material production, especially a powder automatic feeding device. BACKGROUND

[0002] The liquid material of plastic products is a liquid raw material for manufacturing plastic products, which is a combination of substances in a liquid state. Through appropriate processing technology, such as injection molding, casting, coating, etc., it can be solidified or molded into a plastic product with certain shape and performance. Many plastic products need to have certain hardness and rigidity, so powder needs to be mixed in the liquid material. The powder can act as a filler to enhance the hardness and rigidity of the plastic product. When mixing the liquid material with the powder, the liquid material and the powder need to be mixed and stirred in a stirred tank. During the mixing process of the liquid material and the powder, the liquid material is extracted into the stirred tank by an extraction device, and the powder is transported into the stirred tank by a conveying device.

[0003] When the powder is transported into the stirred tank, a screw conveyor is usually used to transport the powder. When the powder is added to the feed hopper of the screw conveyor, the powder will escape due to the impact of the powder on the feed hopper. Moreover, when the powder is discharged from the discharge pipe of the screw conveyor, the powder will also escape because the discharge pipe is not sealed with the stirred tank. The powder escaping into the air can be inhaled by the workers, causing harm to their bodies and wasting the powder. In addition, the escaped powder needs to be cleaned by the workers, which is time-consuming. Based on the above problems, the present application provides a powder automatic feeding device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1-5An automatic powder feeding device includes a mounting bracket 1, a conveying bin 2 fixedly mounted on the top of the mounting bracket 1, a drive motor 3 fixedly mounted on the left end of the conveying bin 2, a feeding auger 4 fixedly mounted on the output end of the drive motor 3, a discharge pipe 6 fixedly mounted on the bottom of the conveying bin 2, a feed hopper 5 and a collection box 7 fixedly mounted on the top of the conveying bin 2, a connecting slot 9 and a feed inlet 22 penetrating through the top of the conveying bin 2, and a discharge outlet 23 penetrating through the bottom of the conveying bin 2. The feed inlet 22 facilitates the entry of powder from the feed hopper 5 into the conveying bin 2, and the discharge outlet 23 facilitates the discharge of powder from the conveying bin 2 through the discharge pipe 6. Inside the mixing tank, a dust extraction fan 8 is fixedly installed on the top of the collection box 7. A filter screen 10 is fixedly installed inside the collection box 7. A collection pipe 1 is installed on the left side of the collection box 7, and a collection pipe 2 is installed on the right side of the collection box 7. The collection pipe 1 includes a collection pipe 11 fixedly installed on the left side of the collection box 7. A rectangular pipe 12 is fixedly installed at the feed end of the collection pipe 11. The rectangular pipe 12 is fixedly installed on the right side of the feed hopper 5. A suction pipe 13 is fixedly installed on the left side of the rectangular pipe 12. The collection pipe 2 includes a conveying pipe 14 fixedly installed on the right side of the collection box 7. A connecting pipe 15 is fixedly installed at the feed end of the conveying pipe 14. The connecting pipe 15 is used for dust collection. A ring-shaped pipe 16 is fixedly installed at one end, and a second suction pipe 17 is fixedly installed at the bottom of the ring-shaped pipe 16. There are several suction pipes 13 and 14, with the first suction pipes 13 arranged in a linear array and the second suction pipes 17 arranged in a circular array. The use of these suction pipes 13 and 17 facilitates the comprehensive collection of any loose powder, preventing incomplete collection. A fixing plate is fixedly installed inside the second suction pipe 17, and the fixing plate is fixedly connected to the discharge pipe 6. When the powder is poured into the feed hopper 5, the suction fan 8 directs the first suction pipe 13 and 14 into the feed hopper 5. Suction pipe 2 17 generates suction to collect the powder escaping from feed hopper 5 through suction pipe 1 13, and to collect the powder escaping from discharge pipe 6 through suction pipe 2 17. The powder sucked by suction pipe 1 13 enters the collection box 7 through rectangular pipe 12 and collection pipe 11, and the powder sucked by suction pipe 2 17 enters the collection box 7 through annular pipe 16, connecting pipe 15 and conveying pipe 14. This facilitates the collection of escaping powder, avoids the escaping powder from affecting the health of workers, and avoids the powder falling to the ground and requiring time to clean up. The collection box 7 is equipped with a blocking component.

[0022] Specifically, the blocking assembly includes a hydraulic push rod 18 fixedly installed on the right side of the collection box 7. A movable plate 19 is fixedly installed at the output end of the hydraulic push rod 18. A blocking plate 20 is fixedly installed on the top of the movable plate 19. The blocking plate 20 is slidably installed inside the collection box 7. A discharge plate 21 is overlapped on the top of the blocking plate 20. The discharge plate 21 is inclined, and there are two discharge plates 21, which are symmetrically distributed. The inclined discharge plates 21 facilitate the collection of powder from sliding off their surface. The discharge plates 21 are fixedly installed. Inside the collection box 7, the output end is shortened by the hydraulic push rod 18, which causes the hydraulic push rod 18 to move the moving plate 19 to the right. The moving plate 19 then moves the blocking plate 20 to below the right discharge plate 21, so that the powder collected in the collection box 7 slides down to below the discharge plate 21 and enters the conveying chamber 2 through the connecting slot 9. The collected powder can then be conveyed to the mixing tank by the feeding auger 4, making it easier to add the collected powder into the conveying chamber 2 and to process the collected loose powder.

[0023] The automatic powder feeding device is connected to a 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0024] In use: Pour the powder to be fed into the inside of the feed hopper 5, start the dust suction fan 8, so that the suction pipe 13 extracts the powder that has escaped from the inside of the feed hopper 5. The extracted powder enters the rectangular tube 12 through the suction pipe 13, and then enters the collection pipe 11 through the rectangular tube 12, and then enters the collection box 7 through the collection pipe 11. The collected powder is blocked by the filter screen 10, so that the collected powder remains in the collection box 7. The drive motor 3 drives the output end to drive the feeding auger 4 to rotate, so that the feeding auger 4 transports the powder to the discharge pipe 6. The powder enters the mixing tank through the discharge pipe 6. At this time, the suction pipe 2 17 extracts the escaped powder. The powder enters the connecting pipe 15 through the annular pipe 16, and then enters the conveying pipe 14 through the connecting pipe 15, and then enters the collection box 7 through the conveying pipe 14. The collected powder is blocked by the filter screen 10, so that the collected powder remains in the collection box 7.
