[0021] 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. Example

[0022] like Figure 1-7 As shown, an embodiment of the present invention proposes a traction device for packaging film production. The traction device designed for packaging film production in this scheme can improve the loading and conduction of the packaging film on the traction device, improve the use effect, and can realize the tension adjustment of different packaging films, improve the tension effect, including a traction base 1, a plurality of positioning connectors 2 are symmetrically connected to the traction base 1, the positioning connector 2 and the traction member 3 are rotatably connected, a tensioning member 4 is slidably connected to the traction base 1, the tensioning member 4 is connected to the counterweight block 5, and there are a plurality of counterweight blocks 5 symmetrically arranged on both sides of the traction base 1. The device is electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. When the traction device of this scheme is needed during the production of packaging film, the plurality of traction members 3 on the traction base 1 are adjusted through the positioning connector 2 so that the plurality of traction members 3 are distributed in two rows, such as Figure 1When the lever 202 is in the locked position, the spring 203 is pulled out of the locking cam 206, and the locking cam 205 is released, so that the locking cam 202 is in the locked position. The lower position is swapped, and the packaging film needs to pass through the bottom of the tensioning member 4, so that the packaging film is used by several electrostatic dust removal rollers 301 and a tensioning member 4 in a wave-like traction conduction. According to the strength of the packaging film, the deadweight of the tensioning member 4 is adjusted by the counterweight block 5, and the number of counterweight blocks 5 installed on the plug-in rod 403 can be adjusted by inserting the pin 405 into the limit hole 502. According to the increase or decrease of the number of counterweight blocks 5, the deadweight of the tensioning member 4 can be adjusted. The tensioning member 4 is above the packaging film, and the traction members 3 on both sides of the tensioning member 4 conduct and support the bottom of the packaging film. Under the action of gravity, the tensioning member 4 will maintain a downward pressure force, so that the packaging film conducted on the traction device can maintain a tensioning effect. When the electrostatic dust removal roller 301 conducts the packaging film, it can remove dust and impurities on the packaging film through electrostatic adsorption, so as to avoid impurities and dust in the packaging film affecting its winding effect and improve the use effect.

[0023] An embodiment of the present invention proposes a traction device for packaging film production, which can also connect a dust removal member 6 to the positioning connector 2. The dust removal member 6 is matched with the electrostatic dust removal roller 301 to clean the impurities and dust adsorbed on the electrostatic dust removal roller 301, thereby improving the dust removal and impurity removal effect. The dust removal member 6 is composed of an electrostatic dust removal plate 601, a nut 602 and a stud 603. Both ends of the electrostatic dust removal plate 601 are symmetrically connected to the nut 602 for rotation. The nut 602 is threadedly connected to the stud 603. The stud 603 is fixedly connected to the sliding block 201 at one end of the electrostatic dust removal roller 301. The threaded connection between the nut 602 and the stud 603 can make the electrostatic dust removal plate 601 convenient to install and disassemble. It is explained here that the dust removal member 6 is installed on the side away from the electrostatic dust removal roller 301 and the packaging film conduction. , ensuring that the dust removal part 6 will not affect the normal conduction and use of the packaging film on the electrostatic dust removal roller 301, the electrostatic adsorption force of the electrostatic dust removal plate 601 is greater than the electrostatic adsorption force of the electrostatic dust removal roller 301, so when the electrostatic dust removal roller 301 is adsorbed with dust or impurities and rotates, when it is at the position of the electrostatic dust removal plate 601, the electrostatic dust removal plate 601 can replace and adsorb the dust and impurities adsorbed on the electrostatic dust removal roller 301, thereby achieving the cleaning and use effect of the dust and impurities on the electrostatic dust removal roller 301. After a large amount of dust and impurities are adsorbed on the electrostatic dust removal plate 601, the dust removal part 6 can be easily disassembled and cleaned, thereby improving the conduction and use of the electrostatic dust removal roller 301 on the packaging film, and avoiding the residual impurities and dust on the electrostatic dust removal roller 301 affecting the conduction effect.
