Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting machine technology, specifically to a paper roll ejection mechanism for a slitting machine. Background Technology
[0002] Currently, small rolls of paper are widely used in cash registers, ticketing, and self-adhesive labels. A small roll typically consists of a core at the center and paper wound around the core. During winding, a large roll of paper is fed through guide rollers and cut into smaller rolls of equal width by the slitting blades of a slitting machine. These smaller rolls are then wound onto the core located between the support rollers and the pressure rollers. Existing patent application CN202210802674.8 discloses a slitting machine including an unwinding shaft, several guide rollers, a slitting blade assembly, a support roller assembly, a pressure arm, a glue-spraying and cutting device, a cutting blade, a pressure roller, and an air blowing pipe. The support roller assembly, pressure arm, cutting blade, pressure roller, and air blowing pipe work together to wind the paper. After winding, multiple mechanisms, such as a core ejector device and a core circulation device, are needed to separate the paper roll from the core. This separation process is complex, cumbersome, and inefficient. Utility Model Content

The pushing assembly includes a conveyor belt 61, a pusher block 62 connected to the conveyor belt 61, and a motor 63 that drives the conveyor belt 61. The initial position of the pusher block 62 is set such that the pusher block 62 passes through the slot 331 at the bottom of the feeding groove 30 from bottom to top and abuts against one end of the paper roll 11 placed in the feeding groove 30. The motor 63 drives the conveyor belt 61 to reciprocate, thereby driving the pusher block 62 to reciprocate. When the conveyor belt 61 moves, it drives the pusher block 62 to move along the slot 331 from one end of the feeding groove 30 to the other end, and the pusher block 62 pushes the paper roll 11 out of the feeding groove 30.
[0035] Specifically, the pushing assembly also includes two wall plates 64 and two pulleys 65 rotatably connected between the two wall plates 64. One end of the two wall plates 64 is fixed to the first vertical mounting plate 22, and the other end of the two wall plates 64 passes through the through slot of the fixing plate 211. A second corner plate 66 is fixed between the wall plates 64 and the fixing plate 211 by screws. The conveyor belt 61 is sleeved on the two pulleys 65. The motor 63 is mounted on the first vertical mounting plate 22, and the output shaft of the motor 63 is connected to one of the pulleys 65 through a gear.

The first cylinder 41, the second cylinder 51 and the motor 63 are controlled by a PLC controller installed on the slitting machine 200 so that the PLC controller can control the paper roll ejection mechanism 100.
[0037] Preferably, the paper roll ejection mechanism 100 further includes an ejection mechanism lifting assembly, which is connected to the mounting bracket and is used to lift the paper roll ejection mechanism 100 as needed. The ejection mechanism lifting assembly includes a lifting cylinder 71 and a cylinder mounting seat 72 connected to the lower end of the lifting cylinder 71. Two lifting cylinders 71 are vertically arranged, and the upper ends of the two lifting cylinders 71 are respectively connected to the first vertical mounting plate 22 and the second vertical mounting plate 23. The cylinder mounting seat 72 is mounted and fixed on the frame 203 of the slitting machine 200, and the paper roll ejection mechanism 100 is driven to lift and lower through the lifting cylinders 71.
[0038] Specifically, lifting cylinder connecting blocks 223 are fixed on the outer surfaces of the first vertical mounting plate 22 and the second vertical mounting plate 23.

A slider 225 is slidably arranged on the guide rail 224. The slider 225 is fixed on the frame 203 of the slitting machine 200.

[0041] like Figure 5As shown, when this utility model is used, the paper roll ejection mechanism 100 is installed on the frame 203 of the slitting machine 200 via a mounting bracket. After the mandrel 10 finishes rolling the paper, the robotic arm 201 on the slitting machine 200 grabs the mandrel 10 that is wound around the paper roll 11 and places the paper roll 11 and the mandrel 10 in a predetermined position in the material placement groove 30. The first cylinder 41 of the mandrel fixing assembly drives the gripper 42 to clamp one end of the mandrel 10. The second cylinder 51 of the mandrel support assembly drives the support block 52 to move to a predetermined position so that the support block 52 supports the other end of the mandrel 10. The pusher block 62 of the pusher assembly passes through the slot 331 at the bottom of the feeding trough 30 from bottom to top and abuts against one end of the paper roll 11 placed in the feeding trough 30; then the second cylinder 51 of the mandrel support assembly drives the support block 52 to move downward so that the support block 52 does not block the paper roll 11; the motor 63 drives the conveyor belt 61 to move, and when the conveyor belt 61 moves, it drives the pusher block 62 to move along the slot 331 from one end of the feeding trough 30 to the other end. The pusher block 62 pushes the paper roll 11 out of the feeding trough 30 onto the discharge conveyor belt 202 of the slitting machine 200, completing the discharge of the paper roll 11; finally, when the pusher block 62 completely pushes the paper roll 11 out of the mandrel 10, the pusher block 62 returns and the second cylinder 51 is activated. The second cylinder 51 of the mandrel support assembly drives the support block 52 to move upward to the original predetermined position, so that the support block 52 supports the other end of the mandrel 10 again.
