[0002] Injection molding machines, also known as injection molding machines or injection machines, are the primary molding equipment used to create various shapes of plastic products from thermoplastics or thermosetting plastics using plastic molding molds. They are available in vertical, horizontal, and all-electric models. Injection molding machines heat plastic and apply high pressure to the molten plastic, ejecting it and filling the mold cavity. During operation, these machines generate a large amount of exhaust gas, which is directly discharged into the air, causing air pollution. Therefore, they require auxiliary waste gas treatment systems.

[0003] In actual work, the structure and function of the exhaust gas treatment mechanism in the existing technology are relatively complete and can meet the basic daily use needs, but there are still the following two problems:

[0004] 1. During the waste gas treatment process, the waste gas is often passed through the disinfectant to eliminate the toxic and harmful substances inside the waste gas. However, the waste gas often contains large particles of impurities, which will cause contamination of the disinfectant and reduce the service life of the disinfectant.

[0005] 2. After the waste gas is treated with disinfectant, the disinfectant will adhere to the gas, which will also pollute the air and affect the surrounding air quality.

[0006] Therefore, the utility model provides an exhaust gas treatment mechanism for an injection molding machine. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 5 As shown, this embodiment provides a technical solution: an exhaust gas treatment mechanism for an injection molding machine, comprising a treatment frame 1, an air inlet pipe 2 fixedly mounted on the top of the treatment frame 1, an air outlet pipe 3 provided on one side of the treatment frame 1; a multiple filtering structure 4 provided on the inner wall and one side of the treatment frame 1; an auxiliary dust prevention structure 5 provided on one side of the air outlet pipe 3; the multiple filtering structure 4 comprising an L-shaped plate 41, the top of the outer surface and one end surface of the L-shaped plate 41 being fixedly connected to the top of the inner wall and one side of the treatment frame 1, a first partition plate 42 and a second partition plate 43 fixedly connected to one side of the outer surface of the L-shaped plate 41, and the second partition plate 43 being located below the first partition plate 42;

[0028] By setting the first partition plate 42 and the second partition plate 43, the internal space of the processing frame 1 can be divided in cooperation with the L-shaped plate 41. The area enclosed by the first partition plate 42 and the second partition plate 43 can be cooperated with the filter plate 412 to assist in filtering large particles of impurities in the exhaust gas. Then, under the action of the disinfectant in the L-shaped space enclosed by the L-shaped plate 41 and the processing frame 1, harmful substances can be filtered. At the same time, under the action of the first filter plate 48 and the second filter plate 49, in cooperation with the activated carbon set in the middle, the disinfectant gas contained in the exhaust gas can be adsorbed.

[0029] A step further, such as Figure 2-Figure 3As shown: the outer surface of the L-shaped plate 41 is fixedly connected to the first filter plate 42 and the second filter plate 43 on the side opposite to the first filter plate 42 and the second filter plate 43, and the second filter plate 49 is located above the first filter plate 48, and the filter hole diameter of the first filter plate 48 is smaller than the filter hole diameter of the second filter plate 49. Activated carbon is placed between the first filter plate 48 and the second filter plate 49, and the second filter plate 48 is fixedly connected to the inner wall of the L-shaped plate 41 with a ventilation pipe 44, and the top end of the ventilation pipe 44 is connected to the space between the first partition plate 42 and the second partition plate 43, and the bottom end of the ventilation pipe 44 is connected to the space of the processing frame 1 located below the L-shaped plate 41. The inner wall of the processing frame 1 is located between the first partition plate 42 and the second partition plate 43 and is fixedly connected with a rectangular limiting sliding frame 45. The inner wall of the rectangular limiting sliding frame 45 is slidably inserted with a filter screen plate 412, and the outer surface of the processing frame 1 is opened There is a rectangular ring groove 46, and the inner wall of the rectangular ring groove 46 is clamped with a rectangular ring block 410. One side of the outer surface of the rectangular ring block 410 is fixedly connected to a cover plate 411, and the top of the outer surface of the cover plate 411 is fixedly connected to a rectangular block 413. The inner wall of the rectangular block 413 is threadedly inserted with a threaded clamping rod 414, and one side of the outer surface of the processing frame 1 is provided with a threaded clamping hole 47. The threaded clamping rod 414 and the threaded clamping hole 47 are detachably threadedly connected. Under the action of the first partition plate 42 and the second partition plate 43, the space enclosed by the L-shaped plate 41 and the processing frame 1 can be separated, and then under the action of the filter screen plate 412 arranged inside, large particles of impurities in the exhaust gas can be filtered. At the same time, under the action of the first filter screen plate 48 and the second filter screen plate 49, the activated carbon can be combined to adsorb the disinfectant liquid in the exhaust gas to avoid pollution caused by discharge into the air.

[0030] The above solution still has the problem that dust and impurities in the external air can easily enter the interior of the processing frame 1 through the outlet pipe 3. Figure 4-5 As shown: In this scheme, the auxiliary dust-proof structure 5 includes an annular clamping frame 51, one side of the outer surface of the annular clamping frame 51 is fixedly connected to one side of the exhaust pipe 3, and the inner wall of the annular clamping frame 51 is clamped with an annular clamping block 52, and one side of the outer surface of the annular clamping block 52 is fixedly connected to a circular filter plate 53, and one side of the outer surface of the circular filter plate 53 is fixedly connected to a clamping tube 54. Under the action of the annular clamping block 52 and the annular clamping frame 51, the circular filter plate 53 can be disassembled and assembled, and then the clamping tube 54 can be used to assist in filtering impurities and dust in the external air to prevent them from flowing into the processing frame 1.

[0031] The above solution also has the problem that dust is easily collected on the outer surface of the circular filter plate 53, thereby reducing the internal exhaust gas discharge efficiency. Figure 5As shown, the inner wall of the circular filter plate 53 is rotatably connected to a rotating circular rod 55, one end of the rotating circular rod 55 is fixedly connected to an operating circular block 56, the outer surface of the rotating circular rod 55 is fixedly connected to a connecting circular block 57, and the outer surface of the connecting circular block 57 is fixedly connected to a brush rod 58. Under the action of the rotating circular rod 55 and the brush rod 58 and other components, the dust on the outer surface of the circular filter plate 53 can be auxiliary cleaned, thereby preventing dust from adhering to the outer surface of the circular filter plate 53 and causing blockage.

[0032] Working principle:

[0033] like Figure 1-5 As shown:

[0034] When in use: connect the air inlet pipe 2 to the air outlet of the injection molding machine. At this time, the air inlet pipe 2 can discharge the exhaust gas into the space between the first partition plate 42 and the second partition plate 43. At this time, the filter plate 412 can assist in cleaning the large particles of impurities in the exhaust gas.

[0035] At this time, the exhaust gas is discharged into the disinfectant at the bottom of the L-shaped plate 41 through the vent pipe 44. Under the action of the disinfectant, the toxic substances in the exhaust gas can be removed. Then, the disinfectant can be adsorbed by the activated carbon between the first filter plate 48 and the second filter plate 49.

[0036] When the filter plate 412 needs to be cleaned, the threaded clamping rod 414 is separated from the threaded clamping hole 47, and then the cover plate 411 is pulled to separate the rectangular ring clamping block 410 from the rectangular limiting sliding frame 45, and then the filter plate 412 is pulled out for cleaning;

[0037] When it is necessary to block impurities in the external air, the annular clamping block 52 is clamped with the annular clamping frame 51, so that the circular filter plate 53 is installed with the exhaust pipe 3. At this time, the clamping tube 54 can be clamped into the interior of the exhaust pipe 3. When a lot of dust accumulates on the outer surface of the circular filter plate 53, the operating round block 56 is rotated to drive the rotating round rod 55 to rotate, and then drive the brush rod 58 to rotate, and then clean it.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
