DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A bag-making and film-blowing machine for degradable plastic bags comprises a mounting base 1, on the upper end surface of which two fixing frames 3 are symmetrically and fixedly mounted, two mounting plates 2 are symmetrically and fixedly connected between the two fixing frames 3, each mounting plate 2 is symmetrically provided with two movable grooves 12 and a plurality of slide grooves 10, each movable groove 12 is provided with a buffer device, a cleaning device is commonly connected between the two buffer devices, each slide groove 10 is provided with a fixing device, a fixing shaft 7 is commonly rotated between the two fixing devices on the same side, an electrostatic roller 8 is fixedly mounted on the outer wall of each fixed shaft 7, and the electrostatic roller 8 can adsorb dust on the degradable plastic bag.

[0023] Two slots 9 are symmetrically formed on the outer wall of each electrostatic roller 8 , and a scraping device is disposed between the two slots 9 .

[0024] Each buffer device includes a second spring 13, and the second spring 13 is fixedly connected in the movable groove 12, one end of the second spring 13 is fixedly connected to a connecting rod 14, and the connecting rod 14 is slidably clamped in the movable groove 12, and the end of the connecting rod 14 away from the second spring 13 is connected to the output end of the cleaning device.

[0025] The cleaning device comprises a connecting plate 4, and the connecting plate 4 is fixedly mounted on one end of the connecting rod 14. A plurality of brushes 17 are arranged on the end of the connecting plate 4 away from the connecting rod 14. The plurality of brushes 17 can clean the surface of the degradable plastic bag more effectively.

[0026] Each fixing device includes a first spring 11, and the first spring 11 is fixedly connected in the slide groove 10, one end of the first spring 11 is fixedly connected to the support rod 5, and the support rod 5 is slidably clamped in the slide groove 10, and the end of the support rod 5 away from the first spring 11 is fixedly installed with a ring 6, and the outer wall of the fixed shaft 7 is rotatably clamped in the ring 6.

[0027] Each scraping device includes two sliders 16, and the two sliders 16 are slidably connected in the two slots 9, and one end of the two sliders 16 is fixedly connected to a scraper 15, and the scraper 15 contacts the outer wall of the electrostatic roller 8. The scraper 15 contacts the outer wall of the electrostatic roller 8 to clean the outer wall of the electrostatic roller 8. Each scraper 15 is made of nylon. It should be noted that such a design can prevent the scraper 15 from damaging the electrostatic roller 8.

[0028] When the utility model is used, firstly, the plastic bag made by the blow molding machine is passed through two electrostatic rollers 8 and the cleaning device and connected to the winding roller.

[0029] As the winding roller is wound, the electrostatic roller 8 can absorb the dust and impurities adsorbed on the surface of the plastic bag, and the stubborn excess materials can be scraped off by the brush 17 as the plastic bag is wound. When the brush 17 is worn, the second spring 13 can drive the connecting rod 14 and the connecting plate 4, so that the multiple brushes 17 can always be in contact with the surface of the plastic bag, so that the multiple brushes 17 can adaptively clean the surface of the plastic bag.

[0030] As the plastic bag is wound, the number of plastic bags on the winding roller will continue to increase. At this time, the plastic bag wound on the winding roller will drive the plastic bag not wound on the winding roller to deviate. At this time, the plastic bag passing between the two electrostatic rollers 8 will compress the electrostatic roller 8. The electrostatic roller 8 will compress the first spring 11 through the collar 6 and the strut 5. The first spring 11 will reset after being stressed. The reset force of the first spring 11 can be transmitted to the strut 5 and the collar 6. At this time, the collar 6 can transmit the reset force of the first spring 11 to the fixed shaft 7. The fixed shaft 7 will drive the electrostatic roller 8 to fit the surface of the plastic bag, so that the electrostatic roller 8 can always fit the plastic bag to perform electrostatic dust removal.

[0031] The surface of the electrostatic roller 8 can be cleaned by moving the scraper 15 to prevent the electrostatic roller 8 from absorbing too much dust and affecting the dust removal effect of the electrostatic roller 8 .
