The wetted plastic film 16 is wetted by the first atomizer 3 and the second atomizer 33, so that the solidified impurities are effectively loosened, which is convenient for cleaning by the blowing device 4 and the cleaning device 5. Although the wetted plastic film 16 is cleaned by the cleaning liquid by the blowing device 4 and the cleaning device 5, it will still be attached with moisture, thereby preventing dust from occurring during shearing.

[0045] In this embodiment, the cleaning device 5 includes a placement box 51, which is placed in the middle of one side of the frame shell 1, and the inner side of the placement box 51 is connected to a motor 52, the output end of the motor 52 is connected to a rotating shaft 53, one end of the rotating shaft 53 is fixedly connected to a transmission plate 54, and both sides of the transmission plate 54 are provided with a first transmission groove 541 and a second transmission groove 542. The power of the transmission plate 54 is used to provide downward and upward power to the first transmission rod 55 and the second transmission rod 56.

[0046] In this embodiment, a first transmission rod 55 is transmission-connected inside the first transmission groove 541, and a first limiting rod 551 is fixedly connected at one end of the first transmission rod 55. The lower end of the first limiting rod 551 slides in a first limiting hole 552 on one side of the extension plate 511, and a first pressing plate on the upper part of the first limiting rod 551 squeezes a first spring body 553, and the lower end of the first spring body 553 is fixedly connected to the upper end surface of the extension plate 511, one end of the first transmission rod 55 is fixedly connected to a first pressing long plate 554, and one end of the first transmission rod 55 is fixedly connected to a first sliding plate 555, and the first sliding plate 555 slides in a first sliding groove 556 on a side wall of the frame shell 1. The first transmission rod 55 is driven by the force to drive the first limiting rod 551 to slide downward inside the first limiting hole 552 and be squeezed on the first spring body 553, and the first transmission rod 55 simultaneously drives the first pressing long plate 554, the first cleaning plate 5541, and the first sliding plate 555 to move downward, and the first sliding plate 555 slides downward inside the first sliding groove 556 and can move downward more stably until the cleaning liquid absorbing cloth on the first cleaning plate 5541 touches the upper surface of the plastic film 16, then the motor 52 can be stopped, and a more comprehensive cleaning of the upper surface of the plastic film 16 can be achieved.

[0047] In this embodiment, the T-shaped groove on the lower end surface of the first pressing long plate 554 is slidably matched with the first cleaning plate 5541, which is conducive to facilitating the replacement of the absorbent cloth.

The second transmission rod 56 is driven by the second limiting rod 561 to slide upward inside the second limiting hole 562 and be squeezed by the second spring body 563. The second transmission rod 56 simultaneously drives the second pressing long plate 564, the second cleaning plate 5641 and the second sliding plate 565 to move upward. The second sliding plate 565 slides upward inside the second sliding groove 566 until the cleaning liquid absorbing cloth on the second cleaning plate 5641 touches the lower surface of the plastic film 16. Then the motor 52 can be stopped to achieve a more comprehensive cleaning of the lower surface of the plastic film 16. By cleaning the first cleaning plate 5541 and the second cleaning plate 5641, impurities attached to the upper and lower surfaces of the plastic film 16 can be removed, and the plastic film 16 can also be comprehensively cleaned, thereby enhancing the cleanliness of the cleaning and improving work efficiency and usability.

[0049] In this embodiment, the T-shaped groove on the lower end surface of the second pressing long plate 564 is slidably matched with the second cleaning plate 5641. Through the sliding match of the first cleaning plate 5541, the second cleaning plate 5641, the first pressing long plate 554, and the second pressing long plate 564, the disassembly and assembly work can be carried out, and then, the first cleaning plate 5541 and the second cleaning plate 5641 can be taken out to replace the absorbent cloth outside, thereby making the replacement work more convenient.

[0050] The working principle of the present invention is:

[0051] In the present invention, the plastic film 16 is first passed through the first conveying device 11, the second conveying device 12, and the shearing device 13 in sequence, and the upper surface is against the lower outer side of the first fixing rod 14 and the second fixing rod 15, and then placed in the plastic film 16. The first inspection door 17, the second inspection door 18, and the third inspection door 19 are set to effectively help workers adjust the position of the plastic film 16 and repair other structures. After the plastic film 16 is placed, the first conveying device 11 and the second conveying device 12 are started to allow the plastic film 16 to be transported to one side in the dustproof space formed by the dust cover 2, the support plate 21, and the combination plate 24. At the same time, the first atomizer 3, the second atomizer 33, the blowing device 4 and the cleaning device 5 are started again. The plastic film 16 that first passes through the first atomizer 3 and the second atomizer 33 is atomized by the first spray rod 31 and the second spray rod 32. After the cleaning liquid is evenly sprayed on the upper and lower surfaces of the plastic film 16, the upper and lower surfaces of the plastic film 16 are wetted, and then the wetted plastic film 16 part.

[0052] Under the continuous conveying, it is conveyed to the position of the blowing device 4, and the blowing port blows the cleaning liquid (the cleaning liquid has fused the dust) on the upper surface of the plastic film 16 into the storage space composed of the support plate 21 and the inclined plate 22. At the same time, the lower surface of the plastic film 16 abuts against the scraper on the upper end surface of the inclined plate 22, scraping off the wet plastic film 16, and letting the scraped cleaning liquid fall into the storage space.

[0053] After scraping and blowing, it is transported to the cleaning device 5. Before that, the motor 52 is started to drive the rotating shaft 53 to drive the transmission plate 54 to rotate clockwise, and the first transmission groove 541 and the second transmission groove 542 are pressed against the first transmission rod 55 and the second transmission rod 56 to move downward in the clockwise direction. Firstly, the first transmission rod 55 is driven by the force to drive the first limiting rod 551 to slide downward in the first limiting hole 552 and squeezed on the first spring body 553, and the first transmission rod 55 simultaneously drives the first pressing long plate 554, the first cleaning plate 5541, and the first sliding plate 555 to move downward, and the first sliding plate 555 slides downward in the first sliding groove 556 until the cleaning liquid absorbing cloth on the first cleaning plate 5541 contacts the upper surface of the plastic film 16, and the motor 52 can be stopped. Secondly, the second transmission rod 56 is driven by the force to drive the first limiting rod 551 to slide downward in the first limiting hole 552 and squeezed on the first spring body 553. The force drives the second limiting rod 561 to slide upward inside the second limiting hole 562 and squeeze the second spring body 563, and the second transmission rod 56 simultaneously drives the second pressing long plate 564, the second cleaning plate 5641, and the second sliding plate 565 to move upward, and the second sliding plate 565 slides upward inside the second sliding groove 566 until the cleaning liquid absorbing cloth on the second cleaning plate 5641 hits the lower surface of the plastic film 16, then the motor 52 can be stopped, and after the first cleaning plate 5541 and the water-absorbing cloth on the second cleaning plate 5641 hit each other, the scraped and blown-off part of the plastic film 16 is cleaned, and then the upper and lower surfaces are cleaned, and the cleaned plastic film 16 enters the second conveying device 12 and the shearing device 13 in turn, and the shearing device 13 shears the cleaned plastic film 16.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the invention should be included in the protection scope of the present invention.
