The invention provides a paper roll shaft pulling device which is matched with a crown block in a workshop for use, is driven by a motor, is specially used for pulling a paper roll shaft from roll paper, has the advantages of simple and reliable structure, small occupied volume and space, high pulling efficiency and convenient operation, can realize the pulling of the paper roll shafts of paper rolls with various diameters and widths, and has wide application size.

In order to achieve the purpose of the invention, the technical scheme is as follows:

a reel shaft pulling device comprises a frame, a front frame arranged above the front part of the frame, and a driven gear fixed below the front frame; a driving gear is arranged above the rear part of the rack, and the driving gear is meshed with a driven gear through a chain; the middle part of the frame is provided with parallel double-track tracks, a shaft pulling trolley is arranged above the tracks and is fixedly connected with the chain, and a shaft clamp is arranged above the shaft pulling trolley.

The driving gear is connected with the three-phase asynchronous motor and the reduction gearbox, and the torque and the rotating speed are increased and reduced through the reduction gearbox by the power output by the motor, so that the driving gear is provided with rotating torque; the driving gear drives the chain to move circularly so as to drive the shaft pulling trolley fixed on the chain to move; the shaft pulling trolley is provided with a photoelectric limit switch which corresponds to the photoelectric limit switches at the front limit position and the rear limit position of the track on the rack, so that the shaft pulling trolley is prevented from moving out of the range of the track; and a chain groove is arranged on the rack below the chain and used for bearing the chain and preventing the chain from drooping under the action of gravity.

The walking wheels are arranged below the rack, and the shaft pulling device can be conveniently moved or steered without being limited by the shape and layout of a factory building.

The supporting roller is arranged above the front frame, and in the shaft pulling process, the roll paper shaft is borne by the supporting roller and is subjected to rolling friction, so that the surface of the roll paper shaft is not scratched, and the roll paper shaft is favorable for being recycled for multiple times.

The middle part of the supporting roll is provided with a groove, the groove limits the paper roll shaft at the middle position of the supporting roll in the drawing process, the paper roll shaft does not slide left and right, the drawing process is carried out along the linear direction, and the paper roll shaft is stable and does not shake.

A limiting plate is arranged above the shaft pulling trolley, a U-shaped notch is formed in the middle of the limiting plate, and the paper winding shaft penetrates out of the U-shaped notch to play a role in limiting the left-right shaking of the paper winding shaft.

An auxiliary limiting plate is arranged above the shaft pulling trolley, so that the displacement of the paper winding shaft in the operation process is further avoided.

The shaft clamp comprises bottom frames on two sides, one side of each bottom frame is hinged to a clamp body, the clamp body is in a door shape, a lead screw is connected to the middle of the clamp body, a wrench is connected to the upper portion of the lead screw, a jaw is connected to the lower portion of the lead screw, two sides of the jaw are connected with guide rails on two sides of the inner side of the clamp body in a sliding mode, a positioning hook is hinged to the free side of the clamp body, and when the positioning hook is locked, the positioning hook is correspondingly hooked with.

When the shaft clamp is in an inoperative state, the clamp body and the positioning hook are in an open position, when shaft pulling operation is needed, one end of the roll paper shaft is placed in a door shape of the shaft clamp, the clamp body is rotated and closed, the positioning hook is swung down and is hooked and embedded with a groove on the outer side of the underframe, the spanner is rotated by hand, the screw rod descends, the V-shaped jaw at the lower end of the screw rod is positioned under the limit of the guide rail and sinks to press the roll paper shaft, and the clamp body cannot be jacked up by the roll paper shaft due to the hooking limit of the positioning hook and loses pressure; after the clamping, the shaft pulling trolley can be opened, and the roll paper shaft is gradually pulled out of the roll paper.

Compared with the prior art, the invention has the substantive characteristics and the progress that:

1. the invention is used with the overhead traveling crane in the workshop, adopt the motor drive, is specialized in pulling the paper roll shaft out of the stock form, its structure is succinct, reliable and durable, it is convenient to maintain, easy to operate, workers are easy to train the upper part, only need to use the sling to cramp the stock form, hang to the front end of the shaft pulling device with the overhead traveling crane, the end of the paper roll shaft passes the limiting plate and assists the limiting plate, the lower part of the paper roll shaft is supported by the backing roll, clamp the end of the paper roll shaft with the shaft clamp, can start the shaft pulling dolly to carry on the pulling operation.

2. The shaft clamp disclosed by the invention is suitable for paper rolls with various diameters, is wide in application range, does not need to replace a clamp, and can be used for adjusting the stroke of the shaft pulling trolley at any time by operating the traveling distance of the shaft pulling trolley, so that the working efficiency can be artificially improved; meanwhile, the invention can realize the function of shaft pulling, the reverse movement of the paper winding shaft clamped by the shaft pulling trolley and the function of the tube core penetrating of the paper winding shaft.

3. The invention has small volume, compact structure and small occupied workshop space, and the arrangement of the travelling wheels can realize the movement of equipment and facilitate the arrangement in a workshop; the device has low production cost, and can be processed and assembled by using universal parts.
