Description

Unwinding mechanism of paper slitting machine

technical field

The utility model relates to a paper cutting machine, in particular to an unwinding mechanism of the paper cutting machine.

Background technique

Paper slitting machine is a kind of paper processing equipment that cuts and rewinds wide-width roll paper into rolls with different widths. Its structure mainly includes unwinding mechanism, winding mechanism and deviation correction mechanism. The unwinding mechanism and the correction mechanism on the machine are set independently of each other, which not only makes the correction operation of the correction mechanism difficult and the alignment accuracy is low, but also causes the overall production cost of the paper slitting machine to be high.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides an unwinding mechanism for a paper slitter that can integrate unwinding and deviation correction.

In order to achieve the above purpose, the utility model provides an unwinding mechanism of a paper slitting machine, including a fixed bottom plate, a moving frame, an unwinding roller, a swing arm, and a lifting cylinder. The moving frame is installed on the fixed bottom plate, And the fixed bottom plate is provided with a linear slide rail, and the mobile frame is correspondingly equipped with a pulley that can slide left and right on the linear slide rail of the fixed bottom plate, and one end of the swing arm is hinged and fixed on the mobile frame , the other end of the swing arm is fixed with an unwinding roller, the lift cylinder is placed vertically up and down, the cylinder body of the lift cylinder is fixed on the middle part of the swing arm, the output shaft of the lift cylinder is connected to the The mobile frame is hinged and fixed.

The beneficial effects of the utility model are: adopting the above structure, since the unwinding roller is fixed on one end of the swing arm, and the other end of the swing arm is hinged and fixed on the moving frame, the moving frame There is also a lifting cylinder between the swing arm and the swing arm, so driven by the lifting cylinder, the swing arm can hinge and swing up and down relative to the moving frame, so that the up and down deviation correction operation of the unwinding roller can be realized; at the same time, the moving frame There are pulleys that can slide left and right on the linear slide rail of the fixed bottom plate, so the mobile frame can slide left and right relative to the fixed bottom plate, and then can realize the left and right deviation correction operation of the unwinding roller. , the unwinding mechanism provided by the utility model can realize the deviation correction operation of the unwinding roller up and down or left and right while the unwinding roller is unwinding, so that the unwinding operation and the deviation correction operation are integrated and realized, greatly reducing The production cost is reduced, and such a structural setting also makes the deviation correction operation easier and the alignment accuracy higher.

The utility model can be further configured to include a deviation correction controller for controlling the up and down movement of the lifting cylinder and driving the mobile frame to slide left and right on the fixed base plate. The deviation correction controller is also connected with a photoelectric sensor. The moving frame is also equipped with several driven rollers parallel to the unwinding roller, and the photoelectric sensor is arranged above the driven rollers.

With the above-mentioned structure, photoelectric sensors are used for sensing, and the deviation-correction operation is uniformly controlled by the deviation-correction controller, so that the deviation-correction operation can be fully automated.

Detailed ways

As shown in Figures 1 and 2, an unwinding mechanism of a paper slitting machine is provided, including a fixed base plate 1, a moving frame 2, an unwinding roller 3, a swing arm 4, a lifting cylinder 5, and a deviation correction controller 6. The mobile frame 2 is installed on the fixed base plate 1, and the fixed base plate 1 is provided with a linear slide rail 11, and the mobile frame 2 is correspondingly equipped with a slide rail that can slide left and right on the fixed base plate linear slide rail 11. Pulley 21, one end of the swing arm 4 is hinged and fixed on the mobile frame 2, the other end of the swing arm 4 is fixed with an unwinding roller 3, and the lifting cylinder 5 is placed vertically up and down , the cylinder body 51 of the lifting cylinder 5 is fixed on the middle part of the swing arm 4, the output shaft 52 of the lifting cylinder 5 is hingedly fixed to the moving frame 2, and the deviation correction controller 6 is used to control the lifting cylinder 5 up and down Action and drive the moving frame 2 to slide left and right on the fixed base plate 1, the correction controller 6 is also connected with a photoelectric sensor 61, and the moving frame 2 is also equipped with several unwinding rollers 3 parallel driven rollers 7, and the photoelectric sensor 61 is arranged above the driven rollers 7.

Adopt above-mentioned structure, because described unwinding roller 3 is fixedly mounted on one end of described swing arm 4, and the other end of described swing arm 4 is then to be hingedly fixed on the movable frame 2, movable frame 2 and swing arm 4 is also provided with a lifting cylinder 5, so under the drive of the lifting cylinder 5, the swing arm 4 can be hinged and swung up and down relative to the moving frame 2, so that the up and down deviation correction operation of the unwinding roller 3 can be realized; The mobile frame 2 is provided with a pulley 21 that can slide left and right on the linear slide rail 11 of the fixed base plate 1, so the mobile frame 2 can slide left and right relative to the fixed base plate 1, and then the unwinding roller can be realized. 3 left and right deviation correction operation, in summary, the unwinding mechanism provided by the utility model can realize the up and down or left and right deviation correction operation of the unwinding roller 3 while the unwinding roller 3 is unwinding, so that the unwinding The integration of operation and deviation correction operation is realized, which greatly reduces the production cost, and this structural setting also makes the deviation correction operation easier and the alignment accuracy higher.
