[0026] This utility model provides a technical solution:

[0027] Please see Figures 1-5 A printer roller cutting and pulling machine includes a support frame 1, a roller conveying device 2, a cutting device 3, and a pulling device 4. The roller conveying device 2, the cutting device 3, and the pulling device 4 are all mounted on the support frame 1. The roller conveying device 2 passes under the cutting device 3 and the pulling device 4. The machine also includes a conveyor belt 5 and a discharge plate 6. The conveyor belt 5 is located below the support frame 1 and is parallel to the roller conveying device 2. The discharge plate 6 is connected to the outlet end of the roller conveying device 2. The outlet end of the discharge plate 6 is connected to a longitudinally arranged guide frame 7. The part of the guide frame 7 connected to the discharge plate 6 is provided with a feed port 8. The bottom of the guide frame 7 is provided with a discharge port, and the guide frame 7 is vertically above the conveyor belt 5.

[0028] The uncut rubber roller is put into the feeding end of the rubber roller conveying device 2, and the rubber roller is gradually advanced through the rubber roller conveying device 2 in turn, and the two ends of the outer sleeve of the rubber roller are cut through the cutting device 3 respectively. The cut ends do not directly fall off the mandrel, and continue to move forward after cutting, reach the pulling device 4 process, and the cut ends of the sleeve on the rubber roller are pulled off by the pulling device 4. After the waste is separated, the rubber roller rolls into the guide frame 7 along the discharge plate 6. Since the guide frame 7 is vertical, and the internal space size is close to the size of the rubber roller, the rubber roller will roll along the guide frame 7 and fall into the tray placed on the conveying belt 5. The tray has equidistantly arranged grooves, and one rubber roller is placed in each groove. The conveying belt 5 drives the tray to move forward a little bit after each rubber roller falls.

[0029] Specifically:

[0030] The rubber roller conveying device 2 includes two symmetrical rack two 22 of two symmetrical rack one 21. The rack one 21 and the rack two 22 on the same side are adjacent. The rack two 22 is supported by the hydraulic rod 24. The rack one 21 is fixed on the support frame 1. The sawteeth and the tooth gap on the rack one 21 and the rack two 22 are consistent in size, and the sawteeth on the rack one 21 and the rack two 22 are staggered one by one. The feeding end of the rack two 22 is flush with the feeding end of the rack one 21, and the discharge end of the rack two 22 is shorter than the discharge end of the rack one 21. The discharge end of the rack one 21 is connected to the discharge plate 6.

[0031] Since the V-shaped tooth gap on the rack one 21 and the V-shaped tooth gap on the rack two 22 are staggered in turn, that is, the end of the rubber roller is in the V-shaped tooth gap of the rack one 21, and the rack two 22 is lower than the rack one 21 in the initial state. When the rack two 22 rises, the side of the V-shaped tooth gap of the rack two 22 close to the discharge direction of the entire device starts to lift the rubber roller. With the gradual rising of the rack two 22, the end of the rubber roller is between the side of the V-shaped tooth gap of the rack two 22 close to the storage direction and the side of the V-shaped tooth gap of the rack one 21 close to the discharge direction. When the rack two 22 is higher than the rack one 21, the rubber roller is separated from the rack one 4. In the moment of separation, the rubber roller rolls along the side of the next V-shaped tooth gap in the rack two 22 close to the storage direction to the side of the V-shaped tooth gap of the rack one 21 close to the storage direction, so as to enter the next V-shaped tooth gap. At this time, the rack two 22 is lowered, and the process is repeated.

[0035] Furthermore, a sleeve 38 is also installed on the rod body, the diameter of which is smaller than that of the cutting blade 37;

[0036] When the rubber roller reaches the cutting station, the rubber roller lifting plate 39 lifts the rubber roller until both ends of the rubber roller are aligned with the round bars 34 on both sides. Then, the cylinder 310 pushes one of the round bars 34 to contact one end of the inner core rod of the rubber roller. After the rubber roller is pushed by the force, it moves closer to the two round bars 34 until the two ends of the core rod are clamped by the round holes of the two round bars 34. Then the rubber roller lifting plate 39 descends, and the motor 33 drives the rubber roller to rotate. At the same time, the cylinder 35 drives the cutting blade 37 to descend. As the rubber roller rotates, its outer sleeve is cut off. The sleeve 38 next to the cutting blade 37 plays a limiting role. During cutting, the sleeve 38 will contact the outside of the rubber sleeve to prevent the cutting blade 37 from cutting the core rod.
