[0002] In the production process of packaging bags, two sets of rotating rollers close to each other are usually used. The rotating rollers can be simply controlled rotating pressure rollers to transport the packaging bags, or printing rollers to print patterns on the surface of the packaging bags.

[0003] Regardless of the function of the above-mentioned rotating roller, after it has been in contact with the packaging bag for a long time, it is easy to be contaminated with debris and dust. If it is not cleaned for a long time, it is easy to contaminate the packaging bag or cause indentations on the packaging bag, causing quality problems. At present, the cleaning method of the rotating roller in the production process of packaging bags is generally that the staff directly cleans it manually, or removes the rotating roller and then cleans it. The above-mentioned direct cleaning method is dangerous and easily causes cleaning blind spots, while the disassembly cleaning method is more cumbersome and time-consuming. Therefore, it is necessary to design an automatic roller cleaning device. Utility Model Content

[0024] Reference Figure 1-Figure 3 According to an embodiment of the utility model, a self-cleaning roller assembly includes a vertical plate 11, between which two rollers 12 distributed up and down are rotatably connected, and the two rollers 12 can rotate and press the packaging bag located therebetween. When the packaging bag is processed by the two rollers 12, impurities are easily retained on the rollers 12. In order to clean the rollers 12, a cleaning assembly for the rollers 12 is also included.

[0025] The cleaning assembly includes a controlled shaft 13 rotatably connected to the vertical plate 11, a connecting plate 14 is fixedly arranged on the controlled shaft 13, a rotating shaft 16 is arranged inside the connecting plate 14, a roller 17 is fixed outside the rotating shaft 16, and a cleaning rubber plate 18 is arranged outside the roller 17;

[0026] It also includes a positioning mechanism for controlling the angle of the controlled shaft 13 so that the cleaning rubber plate 18 can be attached to the upper and lower pressure rollers 12. The positioning mechanism includes a motor 15 fixed on the vertical plate 11, and an output shaft extending from the motor 15 is connected to the controlled shaft 13.

[0027] The motor 15 controls the controlled shaft 13 to rotate so as to control the angle of the connecting plate 14 , thereby enabling the cleaning rubber sheet 18 to be attached to the upper or lower pressure roller 12 , thereby scraping off the cilia or impurities thereon.

[0028] In the second embodiment of the self-cleaning pressure roller assembly, in order to improve the cleaning effect of the cleaning rubber sheet 18, the rotating shaft 16 is configured to be able to rotate relative to the connecting plate 14, and also includes a driving mechanism for driving the rotating shaft 16 to rotate. A plurality of cleaning rubber sheets 18 are provided, and the cleaning rubber sheets 18 are arranged on the roller 17 at equal angles with the axis of the roller 17 as the center.

[0029] The rotating shaft 16 extends to the outside of the connecting plate 14, and the driving mechanism includes a connecting shaft rotatably connected to the connecting plate 14. The connecting shaft is connected to the rotating shaft 16 through a gear set 20, and a friction wheel 21 is installed at the end of the connecting shaft. The friction wheel 21 extends to the right side of the connecting plate 14 and can be attached to the pressure roller 12. In addition, in this embodiment, the rotating shaft 16 extends to the front and rear ends of the connecting plate 14, and the gear set 20, the friction wheel 21 and the connecting shaft are provided in two groups distributed front and back to ensure stable rotation of the roller 17.

[0030] In this embodiment, when it is necessary to clean the pressure roller 12, taking the cleaning of the pressure roller 12 located on the lower side as an example, the pressure roller 12 located on the lower side rotates clockwise, and the motor 15 controls the angle of the connecting plate 14 until the roller 17 and the cleaning rubber sheet 18 are attached to the pressure roller 12 located on the lower side. At this time, the friction wheel 21 abuts against the pressure roller 12 located on the lower side, and then the clockwise rotation of the pressure roller 12 can drive the friction wheel 21 to rotate counterclockwise, and the friction wheel 21 drives the roller 17 and the cleaning rubber sheet 18 to rotate clockwise through the gear set 20. The pressure roller 12 and the cleaning rubber sheet 18 located on its left side both rotate clockwise. At this time, the cleaning rubber sheet 18 can more efficiently clean the cilia or impurities on the pressure roller 12 located on the lower side.

[0031] Similarly, when the pressure roller 12 on the upper side needs to be cleaned, the pressure roller 12 on the upper side rotates counterclockwise, and the roller 17 and the cleaning rubber sheet 18 also rotate counterclockwise when attached to the pressure roller 12, thereby cleaning the cilia or impurities thereon.

[0032] In the third embodiment of the self-cleaning roller assembly, in order to clean the cilia or impurities brushed off by the cleaning rubber plate 18, a vacuum cleaner 22 is also installed on the connecting plate 14.

[0033] In this embodiment, in order to allow all the cilia or impurities scraped off by the cleaning rubber plate 18 to be collected by the vacuum cleaner 22, the connecting plate 14 is composed of a fixing plate 23 and a mounting plate 24, the fixing plate 23 is connected to the controlled shaft 13, the mounting plate 24 is fixed in the fixing plate 23 and extends to the right side of the fixing plate 23, and the mounting plate 24 is provided with two front and rear distributed ones, and the rotating shaft 16 is rotatably connected to the mounting plate 24;

[0034] A negative pressure groove 25 opening to the right is provided in the fixing plate 23, and the negative pressure groove 25 is connected to the air inlet duct in the vacuum cleaner 22. When the cleaning rubber plate 18 scrapes the cilia or impurities on the pressure roller 12, the vacuum cleaner 22 can work and generate negative pressure in the negative pressure groove 25, thereby absorbing the cilia or impurities scraped off by the cleaning rubber plate 18.

[0035] It should be noted that transfer rollers 26 are rotatably connected between the vertical plates 11, and the transfer rollers 26 are located on the upper and lower sides of the cleaning component. When the pressure rollers 12 do not need to be cleaned and the packaging bags need to be transferred or processed, the packaging bags will be transported to the left and around the transfer rollers 26 to avoid interference between the packaging bags and the cleaning component. During this process, the pressure rollers 12 are in a flat state so that the cleaning rubber sheet 18 does not contact any of the pressure rollers 12.

[0036] It should be noted that the pressing roller 12 may only be used to transport the packaging bag, or may be a printing roller or a hot pressing roller.

[0037] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
