Description

Technical Field

[0001] This utility model relates to the field of rewinding technology, specifically to a double-wound composite rewinding device. Background Technology

[0002] A rewinder is a specialized piece of equipment used for paper, mica tape, and film. Its purpose is to rewind the paper rolls (called base rolls) produced by the papermaking machine in sequence, and the paper is made into finished paper before leaving the factory.

[0003] The existing Chinese patent CN213833848U, published on July 30, 2021, discloses a dual-shaft fully automatic rewinding machine for tape production, belonging to the field of tape production equipment. It includes a machine body, on which one unwinding shaft, two take-up shafts and multiple intermediate shafts are arranged. A rewind changing disc is rotatably arranged on the machine body. Both take-up shafts are rotatably arranged at an eccentric position on the rewind changing disc. A support base is arranged on the machine body, which is located above the rewind changing disc. An arrow label supply mechanism is arranged on the support base.

[0004] However, when the above-mentioned device rewinds two paper rolls, it cannot change the overall placement height according to the thickness of the paper rolls. As a result, the overall tension cannot be adjusted as needed during placement and conveying, which leads to a problem of not being very tight during rewinding.

[0005] Therefore, we propose a novel double-wound composite rewinding device to solve the above-mentioned technical problems. Utility Model Content

The screw mounting facilitates installation and removal. Control box 2 is electrically connected to an external power supply via a connecting cable, allowing for easy power reception and control. A double rewinding lifting conveyor mechanism is installed on the upper inner side of the rewinder frame. This mechanism can hold two rolls of raw paper and can be raised and lowered at the top of the rewinder frame, thus adjusting the height of the rewinding conveyor. The conveyor can be adjusted as needed, making it more convenient to adjust the tension of the conveyor. The adjustable conveyor roller is installed on the left side inside the rewinder frame. The height of the adjustable conveyor roller can be adjusted on the left side inside the rewinder frame, which can adjust the tension of the conveyor and assist in the rewinding conveyor. The composite conveyor mechanism 9 is installed in the middle position inside the rewinder frame. The composite conveyor mechanism 9 can composite convey the material of two raw paper rolls. The rewinding workpiece placement rack is installed on the inner right side of the rewinder frame, which facilitates the placement of the rewinded material workpiece, thereby facilitating personnel to handle and operate it.

[0038] The rewinding machine frame includes a bottom frame 1. Support legs 11 are installed at the four corners of the lower end of the bottom frame 1, allowing the bottom frame 1 to be supported. An upper frame 12 is fixedly connected to the upper end of the bottom frame 1, supporting the upper frame 12. A support frame 13 is fixedly connected to the middle of the upper rear edge of the upper frame 12, supporting the support frame 13. A double rewinding lifting conveyor mechanism is installed at the upper end of the support frame 13, allowing it to be raised and lowered.

[0039] A reel is installed on the inner right side of the upper frame 12, which can be rotated to change the reel.

[0040] The composite conveying mechanism 9 includes a rotating roller and a motor. The rotating roller and the motor are keyed together. When the output shaft of the motor rotates, it can drive the rotating roller to rotate. Two rolls of raw paper are wound around the circumference of the rotating roller, so that the composite conveying paper roll can be rotated. The motor is mounted on the support frame 13 by screws, so that it can be stably placed for driving and conveying.

[0041] like Figures 1-3 As shown, the double rewinding lifting and conveying mechanism includes a movable mounting plate 6. Positioning bearings 62 are screwed onto both sides of the upper end of the movable mounting plate 6. The movable mounting plate 6, through the positioning bearings 62 on its inner upper side, achieves rotational positioning. A rewinding roller 7 is rotatably mounted inside the positioning bearings 62. A paper roll can be fixed around the rewinding roller 7. The rewinding roller 7 can rotate in position through the positioning bearings 62. A reduction motor 5 located on the movable mounting plate 6 is keyed to the rear end of the rewinding roller 7. The output shaft of the reduction motor 5 drives the rewinding roller 7 to rotate during rotation. The reduction motor 5 and the movable mounting plate 6 are connected by screws. The geared motor 5 can be stably placed on the movable mounting plate 6 for driving. The lower ends of the movable mounting plate 6 are fixedly connected to the two sides of the lower end of the movable mounting plate 6. The telescopic rod of the first electric telescopic cylinder 63 can change the height position of the movable mounting plate 6 when it is raised and lowered. The first electric telescopic cylinder 63 is fixedly connected to the support frame 13 by the screw mounting plate 61 on the side of the cylinder body. The first electric telescopic cylinder 63 can be stably raised and lowered on the support frame 13 by the screw mounting plate 61. The first electric telescopic cylinder 63 is electrically connected to the control box 2 through the connecting wire. The first electric telescopic cylinder 63 can be controlled to extend and retract through the control box 2.

[0042] During use, the control box 2 can be set with data through the internal PLC for automatic control operation. The control box 2 is installed on the rewinder frame with screws for easy installation and disassembly. The double rewinding lifting conveyor mechanism can hold two raw paper rolls and can be raised and lowered at the top of the rewinder frame to adjust the height of the rewinding conveyor. This allows for adjustments as needed, making it more convenient to adjust the tension of the conveyor. The adjustable conveyor roller can be height-adjusted on the left side inside the rewinder frame to adjust the tension of the conveyor and assist in rewinding. The composite conveyor mechanism 9 can composite convey the material of the two raw paper rolls, and then rewinding and changing materials can be performed through the roll changing tray. The rewinding workpiece placement rack is installed on the inner right side of the rewinder frame, which facilitates the placement of the rewound material workpieces for easy handling by personnel.

The movable roller frame 8 can be positioned and rotated through the roller shaft 83. A movable bearing block 82 is sleeved on the outer periphery of the roller shaft 83. The roller shaft 83 can be positioned and rotated in the movable bearing block 82. A second electric telescopic cylinder 81 is installed on the upper end of the movable bearing block 82 by screws. When the second electric telescopic cylinder 81 is extended and retracted, it can change the position of the movable bearing block 82, which in turn can change the position of the roller shaft 83. The roller shaft 83 can then change the position of the movable roller frame 8, thereby changing the conveying tightness of the paper roll. The second electric telescopic cylinder 81 is installed on the upper frame 12 by screws, so that it can be stably placed for extension and retraction. The second electric telescopic cylinder 81 is electrically connected to the control box 2 through a connecting wire, and the second electric telescopic cylinder 81 can be controlled accordingly through the control box 2.

[0045] A rotating roller corresponding to the movable roller frame 8 is rotatably installed on the inner left side of the upper frame 12, which can assist in conveying.
