DETAILED DESCRIPTION
[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] See also Figure 1-Figure 10 , the utility model provides a technical solution:
[0031] See also Figure 1-Figure 8 As shown, a paper conveying device in a multifunctional color printing machine includes a color printing machine 1 and paper 3, a support rod 16 is provided on one side of the paper 3, a brush 5 is fixedly installed on the outer wall of the support rod 16, a scraper 18 is provided on one side of the brush 5, one side of the scraper 18 is against the outer wall of the brush 5, an arc-shaped support plate 17 is fixedly installed on the bottom of the scraper 18, the arc-shaped support plate 17 is located below the brush 5, and a part of the brush 5 is located inside the arc-shaped support plate 17.
[0032] When the paper 3 is conveyed downward, the paper 3 will pass over the brush 5, so the brush 5 will rotate due to the movement of the paper 3, and the impurities on the paper 3 will adhere to the brush 5 after contacting the brush 5. When the side of the brush 5 with impurities rotates to the scraper 18, one side of the scraper 18 is tightly against the outer wall of the brush 5. Therefore, when the side of the brush 5 with impurities adhered to it rotates below the scraper 18, the scraper 18 will scrape the impurities on the brush 5. This scraping action will destroy the adhesion between the impurities and the brush 5, causing the impurities to fall off the brush 5, and then the impurities will directly fall into the arc-shaped support plate 17, thereby completing the automatic cleaning of the brush 5 and preventing the impurities from continuing to adhere to the brush 5.
[0033] See also Figure 4-Figure 8 A dust collecting frame 21 is disposed at the bottom of the arc-shaped support plate 17 , a through slot 19 is formed in the arc-shaped support plate 17 , and the through slot 19 corresponds to the dust collecting frame 21 , and a pull plate 12 is fixedly mounted on the outer wall of the dust collecting frame 21 .
[0034] After the impurities fall into the arc-shaped support plate 17, they will directly fall into the through groove 19, and then fall directly into the ash collecting frame 21 through the through groove 19. Since the space in the ash collecting frame 21 is large, impurities can be stored for a long time. The user can pull the pull plate 12 at irregular intervals to pull the ash collecting frame 21 out of the frame 4, and then pour out the impurities in the ash collecting frame 21, and then push the ash collecting frame 21 back to its original position to avoid the ash collecting frame 21 being overfilled with impurities.
[0035] See also Figure 3-Figure 4 A frame 4 is fixedly installed on the inner wall of the color printing machine 1, a door panel 6 is arranged on one side of the frame 4, two spring hinges 8 are hinged between the door panel 6 and the frame 4, a side of the pull plate 12 away from the dust collecting frame 21 is close to the door panel 6, and a handle 7 is fixedly installed on the outer wall of the door panel 6.
[0036] The frame 4 supports the guide plate 2 and the paper 3. The spring hinge 8 allows the door panel 6 to be automatically closed after being opened, thereby ensuring the closed state of the frame 4 to prevent dust from floating into the frame 4. The door panel 6 can be opened by holding the handle 7. When the door panel 6 is opened, the pull plate 12 can be pulled to drive the dust collection frame 21 to move.
[0037] See also Figure 4 A pull ring 13 is fixedly mounted on the outer wall of the pull plate 12 , and the pull ring 13 is provided with a plurality of thumb grooves 14 .
[0038] Holding the pull ring 13 can facilitate the pulling plate 12 to move, and the thumb groove 14 provides a gripping force for the pull ring 13, making it convenient to grasp the pull ring 13.
[0039] See also Figure 7The frame 4 is provided with two slide grooves 20 , the paper 3 is located between the two slide grooves 20 , both ends of the support rod 16 are rotatably connected to the inner wall of the support rod 16 , and the brush 5 is against the outer wall of the paper 3 .
[0040] The slide groove 20 provides a space for the paper 3 to be inserted into the frame 4, and allows the paper 3 to pass through the slide groove 20 to leave the frame 4 and enter the color printing machine 1. The support rod 16 is rotatably connected to the inner wall of the slide groove 20, so that the support rod 16 and the brush 5 have the function of rotation, which facilitates the moving paper 3 to drive the brush 5 to rotate.
[0041] See also Figure 1-Figure 8 A guide plate 2 is fixedly installed on the inner wall of the slide groove 20 , the paper 3 is located on one side of the guide plate 2 , the guide plate 2 is located between the two slide grooves 20 , and the guide plate 2 and the paper 3 are both plugged into the frame 4 .
[0042] The guide plate 2 supports the paper 3 so that the paper 3 can slide smoothly along the guide plate 2 into the frame 4 and the color printer 1 . The guide plate 2 is fixed in two slide grooves 20 to provide support for the paper 3 .
[0043] See also Figure 4-Figure 10 A slide bar 15 is fixedly mounted on the inner wall of the frame 4 , and the ash collecting frame 21 is slidably connected to the outer wall of the slide bar 15 .
[0044] The slide bar 15 provides support and guidance for the ash collecting frame 21 , so that the ash collecting frame 21 can slide along the slide bar 15 , thereby preventing the ash collecting frame 21 from falling.
[0045] See also Figure 4-9 A fixing block 24 is fixedly installed on the inner wall of the frame 4, a servo motor 22 is fixedly installed on the top of the fixing block 24, a fixing belt 23 is fixedly connected between the fixing block 24 and the servo motor 22, a connecting rod 11 is connected to the driving end of the servo motor 22, a roller 9 is fixedly installed on the outer wall of the connecting rod 11, and limit plates 10 are fixedly installed on both ends of the roller 9, and the outer wall of the roller 9 is against the outer wall of the paper 3.
[0046] The fixing block 24 and the fixing belt 23 stably fix the servo motor 22 in the frame 4. The servo motor 22 drives the connecting rod 11 and the roller 9 to rotate. The rotation of the roller 9 can drive the paper 3 to move downward continuously. The limiting plate 10 limits the two sides of the paper 3 to prevent the paper 3 from tilting.
[0047] Working principle:
[0048] When the paper 3 is conveyed downward, the paper 3 will pass over the brush 5, so the brush 5 will rotate due to the movement of the paper 3, and the impurities on the paper 3 will adhere to the brush 5 after contacting the brush 5. When the side of the brush 5 with impurities rotates to the scraper 18, one side of the scraper 18 is tightly against the outer wall of the brush 5. Therefore, when the side of the brush 5 with impurities adhered to it rotates below the scraper 18, the scraper 18 will scrape the impurities on the brush 5. This scraping action will destroy the adhesion between the impurities and the brush 5, causing the impurities to fall off the brush 5, and then the impurities will directly fall into the arc-shaped support plate 17, thereby completing the automatic cleaning of the brush 5 and preventing the impurities from continuing to adhere to the brush 5.
[0049] After the impurities fall into the arc-shaped support plate 17, they will directly fall into the through groove 19, and then fall directly into the ash collecting frame 21 through the through groove 19. Since the space in the ash collecting frame 21 is large, impurities can be stored for a long time. The user can pull the pull plate 12 at irregular intervals to pull the ash collecting frame 21 out of the frame 4, and then pour out the impurities in the ash collecting frame 21, and then push the ash collecting frame 21 back to its original position to avoid the ash collecting frame 21 being overfilled with impurities.
