Description

Technical Field

[0001] The utility model relates to the technical field of carton color printing, in particular to a carton color printing developer recovery device. Background Art

[0002] In the production of cartons, in order to facilitate the development of patterns on the surface of the cartons, a developer is generally sprayed onto the surface of the cartons. The developer is generally recovered and reused. Existing recycling devices perform simple filtration to remove paper scraps mixed in the developer. However, this method may cause clogging of the filter plate after long-term use, making it inconvenient to recover the developer.

[0003] Therefore, in order to prevent the problem of clogging of the filter plate, Chinese patent CN214540382U, a carton color printing developer recovery device points out that by setting a knocking plate, a rubber plate and an adjusting rod, when controlling the rotation of the guide roller to transport the spray developer to the cardboard, the protruding structure distributed in an annular shape on the outer side of the knocking plate can squeeze and rotate the adjusting rod of the broken line structure, and under the action of the reset spring, the adjusting rod is controlled to drive the rubber plate to vibrate, so as to facilitate the shaking off of the excess developer on the cardboard, improve the collection efficiency and avoid waste. Secondly, by setting a first movable plate, a second movable plate, a connecting plate and a movable block, the connecting plate with a hole-like structure evenly distributed inside can filter the paper scraps in the recovered developer. Moreover, the connecting plate is detachable for easy cleaning. The movable block can be used to control the first movable plate and the second movable plate to slide in opposite directions, so that the device can continue to operate while cleaning the connecting plate. The above patent uses vibration to vibrate off excess developer, and achieves continuous filtering of paper scraps through the cross movement of the two filter plates, thereby solving the clogging problem. However, the solution of the above patent still has certain shortcomings. Although the patent can control the first movable plate and the second movable plate to slide in opposite directions through the movable block, so that the filtration can continue to operate while cleaning the connecting plate, it cannot achieve long-term continuous operation and cannot operate continuously without cleaning the filter plates. Therefore, there are certain shortcomings.

[0024] 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.

[0025] Example

[0026] See also Figure 1-8The utility model provides the following technical solutions: a carton color printing developer recovery device, comprising an outer frame 1 of the device, a hot air blowing fan 3, a spray structure, and a drive transmission structure. A recyclable filter structure is installed in the outer frame 1 of the device, and the filter structure is connected to the transmission structure. The filter structure includes a filter cartridge 6, a flange connector 7, a first pulley 8, a second pulley 9, a reciprocating screw 10, a baffle 11, a reciprocating block 12, and an arc-shaped brush 13; the flange connector 7 is installed on the left side of the filter cartridge 6, and the filter cartridge 6 passes through the outer frame 1 of the device horizontally, and the outer end of the flange connector 7 is connected to the first pulley 8. A reciprocating screw 10 is also installed horizontally on the inner side of the outer frame 1 of the device. One end of the rod 10 passes through the outer frame 1 of the device and extends to the outside of the outer frame 1 of the device. A second pulley 9 is connected to the outer end of the reciprocating screw 10, and a reciprocating block 12 is movably installed on the outer surface of the reciprocating screw 10. An arc-shaped brush 13 is installed on one side of the reciprocating block 12. The arc-shaped brush 13 contacts the surface of the filter cartridge 6. A baffle 11 is installed laterally on the inner side of the outer frame 1 of the device to prevent the reciprocating block 12 from rotating with the rotation of the reciprocating screw 10. The baffle 11 contacts the front side of the reciprocating block 12. The second pulley 9 and the first pulley 8 are both connected to the drive transmission structure. A paper scrap collection box 37 is also installed on the inner side of the outer frame 1 of the device. The paper scrap collection box 37 is located below the arc-shaped brush 13.

[0027] In this embodiment, the specific working principle is as follows: this device mainly drives the filter structure to rotate by driving the transmission structure. During the rotation, the filter drum 6 rotates, and the developer falling will contact the surface of the filter drum 6 more evenly. When the filter drum 6 rotates, its reciprocating screw 10 rotates, and then the reciprocating block 12 on the surface of the reciprocating screw 10 moves back and forth under the rotation of the reciprocating screw 10, thereby driving the arc-shaped brush 13 to move, and then scraping the paper scraps on the surface of the filter drum 6. The scraped paper scraps will fall into the paper scrap collection box 37 for collection. In this way, continuous filtration can be achieved without cleaning the filter drum 6. The filtered developer will be at the bottom of the device outer frame 1, and then the filtered developer in the device outer frame 1 will be extracted through the pipe and then used again. Therefore, this method solves the problem that the existing developer recovery cannot achieve continuous filtration of impurities in the developer without replacing the filter drum.

[0028] It should also be noted that the carton enters the outer frame 1 of the device through the driven conveying structure, and then the surface of the carton is first sprayed by the spray structure, and then filtered by the filtering structure, and then the developer on the surface of the carton is dried by the hot blower fan 3, and then it is conveyed to the next step. It should also be noted that a filter is also provided in the paper scrap collection box 37. Because the scraped paper scraps themselves contain developer, there will be more developer in the paper scrap collection box 37 after a long period of paper scraps accumulation. Therefore, in order to allow this part of the developer to be filtered and reused, a filter is installed in the paper scrap collection box 37.

[0029] According to the above, the drive transmission structure can be specifically referred to Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 It can be seen that the drive transmission structure is divided into a front transmission structure and a rear transmission structure.

The surface of the second rotating shaft 23 and the surface of the first rotating shaft 19 are both provided with gears, and the gears are connected by a tooth chain to form a transmission relationship. A second bearing seat 28 is also installed on the inner side of the device outer frame 1. The second rotating shaft 23 is connected to the inner ring of the second bearing seat 28. The servo reduction motor 4 drives the first rotating shaft 19 to rotate, and then drives the second rotating shaft 23 to rotate through the action of the gear and the tooth chain. After the second rotating shaft 23 rotates, it drives the rear transmission structure to rotate through the connecting structure.

A transmission belt 31 is sleeved on the surface of the small pulley 30. The transmission belt 31 is also sleeved on the surface of the first pulley 8. The third rotating shaft 27 is rotated through the connection structure, and then the fourth rotating shaft 34 is driven to rotate through the cooperation of the second gear 33 and the second chain 35. Secondly, the rotation of the third rotating shaft 27 drives the small pulley 30 to rotate, and then the first pulley 8 is driven to rotate through the action of the transmission belt 31, and then the filter drum 6 is driven to rotate.

[0032] According to the above, the connection structure can be specifically referred to Figure 5 It can be seen that the connection structure includes a first gear 25 and a first chain 26 ; the first gear 25 is mounted on the surface of the second rotating shaft 23 and the third rotating shaft 27 , and the first chain 26 is sleeved between the two sets of first gears 25 .
