Description
Technical field
It the utility model is related to clothes ironing machine tool equipment technical field, and in particular to a kind of to be used to cut the automatic of baler
Chuck.
Background technology
Cut baler be by raw material yardage roll according to production requirement cut into formulate width bundle bar machinery, shoemaking class,
Clothes, case and bag, shoes and hats, garment accessories, medical supplies, reflectorized material factory, tent factory, umbrella factory, gift wrap, coloured flag make,
It is widely used in the industries such as decoration auxiliary material.In general yardage roll cross section structure is as shown in figure 1, yardage roll center is paper tube.Carry out cutting bundle
It is that paper tube is inserted in the central shaft for cutting baler when bar works, then one end by the claw clamping yardage roll on chuck, then by card
Disk drives yardage roll to rotate, then is cut.The existing chuck for cutting baler typically uses the manual universal chuck on machine tool,
The periphery of yardage roll is clamped by the claw of radial contraction on chuck.The clamping mode of this structure, has the disadvantage that：
1st, only outer circumferential side clamps yardage roll, so to ensure that the clamping of yardage roll consolidates, otherwise it is the length of elongated clamping jaw, or
It is the clamping force for increasing claw.If the length of elongated clamping jaw, then because the clamping part of yardage roll would generally be due to claw
Clamp and deform, it is impossible to be re-used as normal qualified bundle strip material, therefore, the length of elongated clamping jaw is last equivalent to yardage roll is added
The waste of material at end；And if increasing the clamping force of claw, then it can make the inside slight shrinkage deformation of the paper tube in yardage roll, rotation
Paper tube can be caused to distort during cutting, cause the cut lengths of end yardage roll inaccurate, easily there is error；
2nd, cut work every time, clamp yardage roll during beginning and cutting terminate after take away clout, be required to manually operated card
Disk, and hand is also needed to close to chuck when taking clout, not only operating efficiency is low, and larger potential safety hazard be present.
The content of the invention
The purpose of this utility model is to propose a kind of efficient, safety, clamp the firmly automatic chuck for cutting baler.
It is described according to the automatic chuck provided by the utility model for being used to cut baler, including chuck body, key
The end face of chuck body is provided with some tracks along the outside radial setting in center, and the track includes allowing from inside to outside vacancy
Mouth and slide rail, described to make vacancy intraoral provided with the top pawl outwards pushed up by center when chucking work, the slide rail is interior to be provided with when card
The clamping limb that disk is clamped when working by export-oriented center, the drive mechanism of the top pawl and the drive mechanism of the clamping limb are mutually only
It is vertical.
It is of the present utility model to be used to cutting the automatic chuck of baler, it is necessary to coordinate the center as shown in Fig. 2 structures during work
Axle, yardage roll is inserted in central shaft, the top pawl of automatic chuck is inserted between the paper tube of yardage roll end and the minor diameter part point of central shaft
The drive mechanism startup in room, the then clamping limb of automatic chuck, clamping limb ecto-entad move, and clamp the periphery of yardage roll, it
The drive mechanism for pushing up pawl afterwards starts, and top pawl moves from inside to outside, until top pawl is outwards leaned to the paper tube inwall of yardage roll, so as to complete
Simultaneously clamped on inside and outside into yardage roll.
Further, the driving structure of the top pawl includes top pawl rocking arm and pushes up pawl drive disk, and the one of the top pawl rocking arm
End sets the top pawl, and the stage casing of top pawl rocking arm sets fixed pin shaft, and the other end of top pawl rocking arm sets driving bearing pin, the top
Pawl and driving bearing pin are driven by the cylinder positioned at the both sides of the top pawl rocking arm, the top pawl drive disk respectively, top pawl drive disk
Circumference is provided with the bayonet socket for being used for installing the driving bearing pin, and the end face of the chuck body, which is provided with, to be used to install the fixed pin shaft
Pin-and-hole.The driving structure of top pawl can have a variety of, using cylinder driving rotating disk formula top pawl drive disk, then be driven again by top pawl
The bayonet socket of disk circumference drives multiple top pawl rocking arms simultaneously, and not only structure is reliable, and because the rotation amplitude for pushing up pawl drive disk can
With the paper tube internal diameter automatic adaptation held out against with top pawl needs, therefore the internal diameter requirement to paper tube can be reduced, use range is wider.
Further, the lateral surface of the top pawl is provided with tooth form friction portion., can be in top pawl by setting tooth form friction portion
Further prevent paper tube from sliding axially when holding out against paper tube inwall, avoid cutting error, increase reliability.
Further, the driving structure of the clamping limb includes clamping limb driving rocking arm and clamping limb drive disk, described
One end of clamping limb driving rocking arm sets clamping limb, and the other end is flexibly connected by bearing pin with the base of the chuck body, institute
The stage casing for stating driving rocking arm is connected by one end of bearing pin and drive link, the other end and the clamping limb of the drive link
Drive disk is hinged.The structure of clamping limb also drives by the way of cylinder drive disk drives driving rocking arm, can fit clamping limb
The yardage roll of different-diameter is answered, increases the scope of application.
Automatic chuck of the present utility model is with existing for compared with cutting the chuck of baler, having advantages below：
1st, chuck is driven using cylinder, in use, only needing yardage roll being inserted in central shaft, motor switch, you can by clamping
Arm clamps yardage roll periphery, and top pawl holds out against the paper tube internal perisporium of yardage roll, can improve operating efficiency with high degree, improve efficiency about
35%；
2nd, the top pawl for adding inside holds out against the paper tube internal perisporium of yardage roll, the internal diameter requirement to paper tube is reduced, even if making
With the yardage roll of size paper tube bigger than normal, still can above machine-cut cut；Yardage roll periphery is clamped by clamping limb simultaneously and top pawl holds out against cloth
The paper tube internal perisporium of volume, it is possible to reduce cutting effect caused by paper tube deformation is bad during cutting；
3rd, cloth is saved, reduces the loss of yardage roll end, baler output capacity is cut in raising；
4th, human hand operating procedure is reduced, improves production security.
