[0013] (3) Beneficial effects

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] During the winding process, the utility model can achieve the goal of pulling the packaging bag to a horizontal state because the height of the traction roller is the same as the traction and winding height of the winding roller. At this time, the scraper symmetrically installed on one side of the winding roller can effectively scrape the upper and lower sides of the rolled packaging bag respectively, thereby reducing the wrinkles on both sides of the packaging bag. In addition, the scraper can also indirectly scrape off the impurities adsorbed on the upper and lower sides of the packaging bag during the scraping process. It is worth mentioning that the personnel need to start the exhaust fan in the installation box in advance so that the hose connected to one side of the installation box and the air guide cover at the end thereof can provide corresponding suction force. Since the symmetrically arranged air guide covers are positioned opposite to both sides of the packaging bag, the scraped impurities can be directly sucked in and introduced into the dust collection box. The subsequent personnel can pull out the dust collection box for cleaning. In addition, it should be noted that when the number of turns of the packaging bag by the winding roller is large, the winding thickness is also large. At this time, the height of the traction roller and the reserved space in the middle of the symmetrical scraper frame will form an angular deviation with the packaging bag, which will affect the normal scraping. At this time, the personnel can start the motor to rotate the transmission screw, and the screw sleeve acting on the screw will carry the assembly frame to cooperate with the slide rod for height adjustment. Since the first side slider, scraper frame and the second side slider, traction roller are respectively connected on both sides of the assembly frame, the height of the scraper frame and traction roller can be adjusted to adapt to the thickness requirements of the packaging bag wound by the winding roller at any time. Finally, all the above structures are fully applicable to the two winding areas of the dual-channel mounting frame separated by two partition plates, so as to achieve efficient winding operation of dual-channel traction of two EPE packaging bags at the same time.

[0016] During the rewinding process of the EPE packaging bag of the utility model, the presence of the movable tensioning roller can assist in effectively pressing the EPE packaging bag during transmission, thereby preventing the packaging bag from becoming loose during rewinding. The adjustment method of the movable tensioning roller is simple. It only requires removing the positioning bolt rod by thread and adjusting the height of the fixed guide blocks on both sides of the movable tensioning roller in the middle of the guide groove.

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.

A positioning bolt rod 46 is screwed in the middle of the first screw-mounted groove 44 and the corresponding second screw-mounted groove 45. During the winding process of the EPE packaging bag, the presence of the movable tensioning roller 43 can help to effectively press the EPE packaging bag in transmission to avoid loosening of the packaging bag during winding. The adjustment method of the movable tensioning roller 43 is simple. You only need to remove the positioning bolt rod 46 by threading and adjust the height of the fixed guide blocks 42 on both sides of the movable tensioning roller 43 to be in the middle of the guide groove 41.

[0026] Among them, the cleaning mechanism 5 includes a fixed frame 51, and the fixed frame 51 is fixed to the middle of the two partition plates 2, and a cleaning component 52 is installed in the middle of the fixed frame 51 and on the inner side of each of the two partition plates 2. The cleaning component 52 includes a transmission screw 521, and the transmission screw 521 is installed on one side of the middle of the fixed frame 51. One end of the transmission screw 521 is connected to the motor 522, and a screw sleeve 523 is screwed on the periphery of one side of the transmission screw 521. The outer wall of the screw sleeve 523 is fixed with an assembly frame 525. Another slide rod 524 for guiding the assembly frame 525 is fixed in the middle of the fixed frame 51, and a first side slider 526 is fixed on one side of the inner side of both sides of the assembly frame 525. The first side slider A scraper 527 is symmetrically fixed on the inner side of 526, a second side slider 528 is fixed on the other side of the inner side of the assembly frame 525, and a traction roller 529 is movable on the inner side of the second side slider 528. The first side slider 526 connected to the rear end of the scraper 527 and the second side slider 528 connected to the rear end of the traction roller 529 respectively form a sliding connection with the distributed sliding grooves 53. Sliding grooves 53 are provided on the inner sides of the two partition plates 2 and the inner walls of the two sides of the dual-channel mounting frame 1, and a cleaning component 2 54 is jointly installed on the inner and outer sides and the upper part of the two partition plates 2. The cleaning component 2 54 includes a deflector 541, and the deflector 541 is symmetrically fixed to the inner sides of the two partition plates 2. The end is connected to a hose 542, and the ends of the two sets of hoses 542 are connected to a mounting box 543, an exhaust fan 544 is installed inside the mounting box 543, and the other end of the mounting box 543 is connected to a dust collecting box 545, a dust guide plate 546 is fixed inside the dust collecting box 545, and a dust collecting box 547 is movably provided at the bottom end of the dust collecting box 545, a dust filter 548 is installed on one side of the dust collecting box 545, the end of the dust guide plate 546 is mounted on one side of the dust collecting box 547, and the dust collecting box 547 and the dust collecting box 545 are movably connected. During the winding process, since the height of the traction roller 529 is the same as the traction and winding height of the winding roller 3, the winding end of the packaging bag can be pulled to a horizontal state. At this moment, the scraper 527 symmetrically installed on one side of the winding roller 3 can effectively scrape the upper and lower sides of the rolled packaging bag respectively, thereby reducing the wrinkles on both sides of the packaging bag, and the scraper 527 can also indirectly scrape off the impurities adsorbed on the upper and lower sides of the packaging bag during the scraping process. It is worth mentioning that the personnel need to start the exhaust fan 544 in the installation box 543 in advance, so that the hose 542 and the end guide cover 541 distributed and connected on one side of the installation box 543 can provide corresponding suction force. Since the symmetrically arranged guide cover 541 is positioned opposite to both sides of the packaging bag, the impurities scraped above can be directly sucked in and introduced into the dust box 545. The subsequent personnel can pull out the dust box 547 for cleaning.

[0027] In addition, it should be noted that when the winding roller 3 winds up a large number of packaging bags, the winding thickness is also large. At this time, the height of the traction roller 529 and the reserved space in the middle of the symmetrical scraper 527 will form an angular deviation with the packaging bag, which will affect the normal scraping. At this time, the personnel can start the motor 522 to rotate the transmission screw 521, and the screw sleeve 523 acting on the screw will carry the assembly frame 525 to cooperate with the slide bar 524 for height adjustment. Since the two sides of the assembly frame 525 are respectively connected to the first side slider 526, the scraper 527 and the second side slider 528, and the traction roller 529, the height of the scraper 527 and the traction roller 529 can be adjusted to adapt to the thickness requirements of the packaging bag wound by the winding roller 3 at any time. Finally, all the above structures are fully applicable to the two winding areas of the dual-channel mounting frame 1 separated by two partition plates 2, thereby achieving efficient winding operation of dual-channel traction of two EPE packaging bags at the same time.

[0028] Working principle: During the rewinding process of the EPE packaging bag, the presence of the active tensioning roller 43 can help to effectively press the EPE packaging bag in transit to avoid the bag from becoming loose during rewinding. The adjustment method of the active tensioning roller 43 is simple. You only need to remove the positioning bolt rod 46 by thread and adjust the height of the fixed guide blocks 42 on both sides of the active tensioning roller 43 to the middle of the guide groove 41. Secondly, during the rewinding process, since the height of the traction roller 529 is the same as the traction and rewinding height of the rewinding roller 3, the rewinding end of the packaging bag can be pulled to In the horizontal state, the scraper 527 symmetrically installed on one side of the winding roller 3 can effectively scrape the upper and lower sides of the rolled packaging bag respectively, thereby reducing the wrinkles on both sides of the packaging bag. In the scraping process, the scraper 527 can also indirectly scrape off the impurities adsorbed on the upper and lower sides of the packaging bag. It is worth mentioning that the personnel need to start the exhaust fan 544 in the installation box 543 in advance so that the hose 542 and the end guide cover 541 connected to one side of the installation box 543 can provide corresponding suction. Due to the symmetrical arrangement of the guide cover 541 The position is opposite to both sides of the packaging bag, so the impurities scraped above can be directly sucked in and introduced into the dust box 545. The subsequent personnel can pull out the dust box 547 for cleaning. In addition, it should be noted that when the winding roller 3 winds the packaging bag a large number of times, its winding thickness is also large. At this time, the height of the traction roller 529 and the reserved space in the middle of the symmetrical scraper 527 will form an angular deviation with the packaging bag, which will affect the normal scraping. At this time, the personnel can start the motor 522 to rotate the transmission screw 521, and the screw sleeve 523 acting on the screw will bring The assembly frame 525 cooperates with the slide bar 524 to adjust the height. Since the first side slider 526, the scraper 527 and the second side slider 528, the traction roller 529 are respectively connected on both sides of the assembly frame 525, the height of the scraper 527 and the traction roller 529 can be adjusted to adapt to the thickness requirements of the winding roller 3 for winding the packaging bag at any time. Finally, all the above structures are fully applicable to the two winding areas of the dual-channel mounting frame 1 separated by two partition plates 2, so as to achieve efficient winding operation of dual-channel traction of two EPE packaging bags at the same time.

[0029] All technical features in this embodiment can be freely combined according to actual needs.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
