Novel paper slitting device

Technical Field

The utility model relates to a paper cutting device, in particular to a novel paper slitting device.

Background

In the paper production industry, paper cutting processes are available, and cutting equipment required by different paper specifications is different. Paper that comes out from the paper mill is general all roll-shaped, when needs are to roll-shaped paper cutting, just need use the paper to cut the device, the device mainly includes the frame, feed mechanism, winding mechanism and cutting knife, paper raw materials rotates and installs at feed mechanism, winding mechanism is through rotating the paper that stimulates on the feed mechanism, make the continuous winding of paper on the feed mechanism on itself, the cutting knife is located the transfer route of paper, consequently, the paper on the winding mechanism is through cutting back paper. The paper of winding mechanism need take off after reaching fixed winding size, nevertheless because the internal stress of gathering together constantly among the winding process for produce great frictional force between the axis body of scroll and winding mechanism, it is very hard to take off the scroll.

Disclosure of Invention

The utility model provides a novel paper slitting device; the problem of have among the prior art that frictional force is too big between the winding axle of scroll and winding mechanism is solved.

The technical problem of the utility model is mainly solved by the following technical scheme: the utility model provides a novel paper is cut device, includes frame, feed mechanism, winding mechanism and cutting knife, the last paper warp of feed mechanism quilt behind the cutting knife cutting the winding mechanism winding is web-like, winding mechanism includes main shaft, the fixed first stationary blade of relative main shaft, the fixed second stationary blade of relative main shaft, connects the eccentric shaft between first stationary blade and second stationary blade, the eccentric shaft is equipped with a plurality ofly and distributes about main shaft circumference array, the pivot of eccentric shaft with the axial direction parallel of main shaft, be fixed with driven gear on the eccentric shaft, rotate on the main shaft be connected with driven gear meshing's driving gear rotates the driving gear can drive all eccentric shaft synchronous rotations in step.

The winding mechanism is provided with a plurality of eccentric shafts distributed in a circumferential array manner, cut paper is wound on an outer indexing circle formed by the eccentric shafts, and the size of the outer indexing circle is variably set. Specifically, the main shaft is kept fixed, then the driving gear on the main shaft is rotated to drive all the driven gears to synchronously rotate, so that the eccentric shaft is driven to rotate, and the diameter of the outer indexing circle is regularly increased and reduced along with the rotation of the eccentric shaft. Therefore, when the winding machine works, the size of the winding external indexing circle on the winding mechanism needs to be adjusted to the maximum; when the paper roll on the eccentric shaft needs to be unloaded, the driving gear is rotated, and the external indexing circle size is reduced, so that the friction force between the paper roll and the eccentric shaft can be effectively reduced.

Furthermore, a locking block is assembled on the first fixing piece in a sliding mode, and one end of the locking block can be in limiting clamping with the driving gear. When the eccentric shaft is in operation, the locking block is required to be clamped with the driving gear, and the eccentric shaft is prevented from rotating due to the relative rotation of the driving gear and the first fixing plate.

Furthermore, a return spring for pushing the locking block to slide towards one side of the driving gear is further arranged on the first fixing piece, so that the locking block can be clamped with the driving gear in real time.

Further, the first fixing piece is circular, and the outer diameter of the first fixing piece is larger than the diameter of an outer indexing circle formed by the eccentric shaft; the main shaft is located on the outer side of the second fixing piece, a circular movable piece is sleeved on the outer side of the second fixing piece, and the outer diameter of the movable piece is consistent with that of the first fixing piece. Therefore, the two sides of the paper roll can be positioned by the first fixing piece and the movable piece, and when the paper roll needs to be unloaded, the paper roll can be separated from one side of the second fixing piece as long as the movable piece is taken down.

Further, still be equipped with motor and speed reduction drive mechanism in the frame, speed reduction drive mechanism's output with winding mechanism transmission is connected.

Therefore, compared with the prior art, the utility model has the following characteristics: 1. the relative position of each eccentric shaft is adjusted by rotating the driving gear, so that the diameter of an outer indexing circle formed by the eccentric shafts is adjusted, the internal stress between the paper roll and the eccentric shafts is eliminated, the friction force is reduced, and the paper roll is convenient to unload.
