However, existing film blowing machines may not be able to suck and collect the odors and exhaust gases, causing the gases to diffuse into the operation workshop, which may affect the working environment of the workshop. Moreover, constantly being in an environment of exhaust gases after plastic heating and melting may also cause great harm to the physical health of the staff. Therefore, an exhaust gas treatment device for greenhouse film processing is provided. Content of the Utility Model

Specific implementation mode

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-4 , the present invention provides a technical solution: an exhaust gas treatment device for greenhouse film processing, including a frame 1; a processing box 2 is arranged on one side of the frame 1 and is used for treating the peculiar smell and exhaust gas generated when the blowing machine heats and melts the plastic particles to blow the film; a cavity 3 is arranged on the top of the frame 1; a negative pressure fan 4 is arranged on the processing box 2; a connecting pipe 5 is arranged between the negative pressure fan 4 and the cavity 3; by starting the negative pressure fan 4, a negative pressure is generated in the cavity 3, and a plurality of air passages 6 are provided and evenly distributed inside the frame 1; a connecting hose 7 is arranged between the top of the air passage 6 and the cavity 3; a plurality of collection assemblies 8 are provided and evenly distributed on the side walls of the air passage 6; an adjustment assembly 9 is arranged on the frame 1 and is used to drive the distance between a plurality of air passages 6 and the film. During use, first start the adjustment assembly 8 according to the preset film width to adjust the position of the air passage 6, and start the negative pressure fan 4, so that the peculiar smell and exhaust gas generated when the blowing machine heats and melts the plastic particles to blow the film enter the processing box 2 after passing through the collection assembly 8, the air passage 6, the connecting hose 7, the cavity 3 and the connecting pipe 5 in sequence. By covering the outside of the film with a plurality of collection assemblies 8, it is ensured that the peculiar smell and exhaust gas are sucked and collected, effectively avoiding the diffusion of gas into the operation workshop and affecting the working environment of the workshop, and effectively reducing the harm to the health of the staff caused by being in the environment of plastic heating and melting for a long time.

[0027] Specifically, the adjusting assembly 9 includes a number of bidirectional threaded rods 9-1 rotatably mounted on the frame 1. Two sliders 9-2 are oppositely arranged on the side wall of the bidirectional threaded rod 9-1. One end of two connecting rods 9-3 is hinged to the two sliders 9-2, and the other end of the connecting rod 9-3 is hingedly connected to the air passage 6. The two connecting rods 9-3 are hingedly connected to the middle of the air passage 6. At the top rotating shaft end of the bidirectional threaded rod 9-1, there are two driving rollers 9-4. The driving rollers 9-4 between adjacent bidirectional threaded rods 9-1 are connected by belt drive. A driving motor 9-5 for driving one of the driving rollers 9-4 to rotate is arranged on the frame 1. During use, the driving motor 9-5 is started to drive one of the driving rollers 9-4 to rotate. One of the driving rollers 9-4 drives the adjacent driving roller 9-4 to rotate through the transmission belt, so as to realize that the driving motor 9-5 drives a number of bidirectional threaded rods 9-1 to rotate simultaneously. The rotation of the bidirectional threaded rod 9-1 drives the two sliders 9-2 to move relatively, and drives the two connecting rods 9-3 to rotate to drive the air passage 6 to move, so as to adjust the distance between a number of air passages 6.

[0028] Specifically, the collecting assembly 8 includes an arc-shaped cavity 8-1 communicated with the air passage 6. By making the arc-shaped surface of the arc-shaped cavity 8-1 adapt to the side wall of the film, the covering area of the collecting assembly 8 for the film is increased. Collecting covers 8-2 are arranged at both the upper and lower ends of the arc-shaped cavity 8-1. The collecting covers 8-2 are used to absorb the odor and waste gas on both the upper and lower sides of the arc-shaped cavity 8-1. A buffer pad 8-3 is arranged at one end of the collecting cover 8-2 close to the film. By setting the buffer pad 8-3, the contact between the film and the collecting cover 8-2 is prevented, effectively preventing the damage of the film. During use, by arranging the collecting covers 8-2 at both the upper and lower ends of the arc-shaped cavity 8-1, the efficiency of collecting the odor and waste gas generated during the heating and melting of plastic particles for film blowing is improved.

[0029] Specifically, a number of collecting assemblies 8 on adjacent two air passages 6 are arranged staggeredly. By the staggered arrangement of a number of collecting assemblies 8, the covering area outside the film is realized, ensuring the complete collection of the odor and waste gas generated during the heating and melting of plastic particles for film blowing, and improving the collection effect of the odor and waste gas.

[0030] Specifically, guide rods 10 penetrating the frame 1 are arranged on the side wall of the air passage 6. There are at least two groups of guide rods 10, and each group has two guide rods. The two groups of guide rods 10 are oppositely arranged on the air passage 6, ensuring the stability of the movement of the air passage 6 when adjusting the position of the air passage 6.

[0031] Working principle: During the use of the utility model, first start the adjusting component 9 to adjust the position of the air passage 6 according to the preset diameter. When the film blowing machine blows the film, start the negative pressure fan 4, so that the odor and waste gas generated during the heating and melting of the plastic particles enter the treatment box 2 after passing through the collection component 8, the air passage 6, the connecting hose 7, the cavity 3 and the connecting pipe 5 in sequence, realizing the collection and treatment of the waste gas.
