Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device with adsorption and filtration functions. Background Technology

[0002] Automatic foam molding machines are one of the most commonly used molding machines in industry. Existing automatic foam molding machines have a feeding mechanism that includes a material tank and a material gun; the raw material enters the mold from the material tank through the material gun for molding.

[0003] Existing automatic molding machines for raw foam plastics crush the material during feeding, generating significant amounts of dust. The lack of a dust absorption mechanism means that long-term inhalation of this dust poses a serious health hazard to workers, reducing the practicality of the equipment. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, one of the objectives of this utility model is to provide a feeding device with adsorption and filtration functions. Through the feeding hopper, crushing mechanism, and adsorption / filtration components, during feeding, the crushing mechanism crushes the raw materials, while the adsorption / filtration components simultaneously adsorb and filter the dust and gas generated during crushing. An inclined filter screen filters the dust and particles. The accumulated dust or particles fall into the feeding hopper through inlet one and inlet two for recycling, improving resource utilization. The gas after the initial filtration is then filtered a second time by an activated carbon plate to remove odors and harmful components, preventing dust and harmful gases from posing a health hazard to workers. When replacing or cleaning the filter screen or activated carbon plate, the handle can be easily pulled out for cleaning via inlet one, inlet two, a sealing baffle, and a handle.

[0023] Reference Figure 1-4 The present invention provides a feeding device with adsorption and filtration functions, which includes: a feeding hopper 1, a crushing mechanism 2 inside the feeding hopper 1, an adsorption and filtration assembly 4 above the feeding hopper 1, and a material inlet 101 on the side wall of the feeding hopper 1.

[0024] The crushing mechanism 2 includes a motor 203 and crushing rollers 201 arranged symmetrically at the front and back. Guide plates 3 are symmetrically arranged above the crushing rollers 201. The side walls of the guide plates 3 are fixedly connected to the inner side wall of the feed hopper 1. Both ends of the crushing rollers 201 are rotatably connected to the left and right side walls of the feed hopper 1. Gears 202 are fixedly connected to the left end of the crushing rollers 201. The two gears 202 mesh with each other. The output end of the motor 203 is fixedly connected to the left end of one side of the crushing roller 201. A fixed mounting plate 204 is fixedly connected to the outer side wall of the motor 203. The side wall of the fixed mounting plate 204 is fixedly connected to the left side wall of the feed hopper 1.

[0025] The adsorption filtration assembly 4 includes a filter box 401, the side wall of which is fixedly connected to the side wall of the feed hopper 1. A suction fan 402 is installed through the top of the filter box 401, and a ventilation pipe 403 is connected through the suction port of the suction fan 402. Two branch pipes 404 are connected through the top of the ventilation pipe 403, and dust collection hoppers 405 are connected through both ends of the branch pipes 404. The two dust collection hoppers 405 are arranged symmetrically front and back and are located above the feed hopper 1. The front wall of the filter box 401 has two insertion holes, a first insertion hole 4011 and a second insertion hole 4012, arranged from top to bottom. The first insertion hole 4011 is inclined, and a filter screen 406 is slidably connected to the inner side wall of the first insertion hole 4011. The second insertion hole 4012... An activated carbon plate 407 is slidably connected to the inner wall. A sealing baffle 408 is fixedly connected to the front wall of both the filter screen 406 and the activated carbon plate 407. A sealing ring is fixedly connected to the rear wall of the sealing baffle 408. A handle 409 is fixedly connected to the front wall of the sealing baffle 408. A support plate 410 is provided below both the filter screen 406 and the activated carbon plate 407. The side walls of the support plate 410 are welded and fixed to the inner wall of the filter box 401. A second feed port 4014 is opened on the side wall of the filter box 401 adjacent to the feed hopper 1. The positions of the first feed port 101 and the second feed port 4014 are corresponding and both are located below the crushing roller 201. The second feed port 4014 is located above the filter screen 406. A ventilation hole 4013 is opened at the bottom of the filter box 401. When feeding is performed via the feed hopper 1, crushing mechanism 2, and adsorption filter assembly 4, the raw material falls between the two crushing rollers 201 along with the guide plate 3. The motor 203 drives one side of the crushing roller 201 to rotate, and through the transmission of two gears 202, it drives the other side of the crushing roller 201 to rotate synchronously, crushing the raw material. At the same time, the suction fan 402 extracts the dust and gas generated by crushing through the dust collection hoppers 405 on both sides. The extracted dust enters the filter box 401 through the branch pipe 404 and the ventilation pipe 403. The inclined filter screen 406 filters the dust and particles. The filtered dust or particles fall into the feed hopper through the feed inlet 101 and the feed inlet 2014. The gas is recycled within the hopper 1, improving resource utilization by recycling while cleaning. The gas after the initial filtration is filtered a second time by the activated carbon plate 407 to remove odors and harmful components. The filtered gas is then discharged through the ventilation hole 4013, preventing dust and harmful gases from posing a health hazard to workers. When replacing or cleaning the filter screen 406 or activated carbon plate 407, the handle 409 can be easily removed by pulling it out. The sealing ring on the sealing baffle 408 enhances the sealing at the connection with the insertion holes 4011 and 4012.

[0026] Working principle: During use, when feeding, the raw material falls between the two crushing rollers 201 along with the guide plate 3. The motor 203 drives one side of the crushing roller 201 to rotate, and through the transmission of two gears 202, it drives the other side of the crushing roller 201 to rotate synchronously, crushing the raw material. At the same time, the suction fan 402 extracts the dust and gas generated by crushing through the dust collection hoppers 405 on both sides. The extracted dust enters the filter box 401 through the branch pipe 404 and the ventilation pipe 403. The inclined filter screen 406 filters the dust and particles. The filtered dust or particles fall into the feed hopper 1 through the feed port 101 and the feed port 2 4014 for recycling. Cleaning and recycling at the same time improves the resource utilization rate. The gas after the first filtration is filtered a second time by the activated carbon plate 407 to filter out the odor and harmful components in the gas. The filtered gas is discharged through the ventilation hole 4013, avoiding the harm of dust and harmful gases to the health of the workers.
