Description
Technical Field
The invention relates to the technical field of garment ironing mechanical equipment, in particular to an automatic chuck for a slitting and bundling machine.
Background
The cutting and bundling machine is a machine for cutting raw material cloth rolls into bundling strips with a set width according to production requirements, and is widely applied to industries such as shoemaking, clothing, bags, shoe caps, clothing accessories, medical supplies, reflective material factories, tent factories, umbrella factories, gift packaging, color flag making, decoration accessories and the like. The general sectional structure of the cloth roll is shown in fig. 1, and the center of the cloth roll is a paper tube. When the bundle strip cutting operation is carried out, the paper tube is sleeved into the central shaft of the bundle strip cutting machine, one end of the cloth roll is clamped by the clamping jaw on the clamping disc, and then the clamping disc drives the cloth roll to rotate, and then cutting is carried out. The chuck of the existing bale cutting machine generally adopts a manual universal chuck on a common machine tool, and the periphery of the cloth roll is clamped by radially contracted clamping jaws on the chuck. The clamping mode of the structure has the following defects:
1. the cloth roll is clamped only by the periphery, so that the clamping stability of the cloth roll is ensured, the length of the clamping jaw is prolonged, or the clamping force of the clamping jaw is increased. If the length of the clamping jaw is lengthened, the clamping part of the cloth roll is deformed usually due to clamping of the clamping jaw and can not be used as a normal qualified binding strip material any more, so that the length of the lengthening clamping jaw is equivalent to the increase of material waste at the tail end of the cloth roll; if the clamping force of the clamping jaw is increased, the paper tube in the cloth roll is slightly contracted and deformed inwards, the paper tube is twisted during rotary cutting, the cutting size of the cloth roll at the tail end is inaccurate, and errors are easy to occur;
2. every time cutting work, press from both sides tight yardage roll at the beginning and take the clout after cutting, all need manual operation chuck to still need the hand to be close to the chuck when taking the clout, work efficiency is low, has great potential safety hazard moreover.

1. the chuck is driven by the air cylinder, when the chuck is used, the outer periphery of the cloth roll can be clamped by the clamping arm by only sleeving the cloth roll into the central shaft and the electric switch, and the inner peripheral wall of the paper tube of the cloth roll is tightly propped by the propping claw, so that the working efficiency can be greatly improved, and the efficiency is improved by about 35%;
2. the inner peripheral wall of the paper tube with the inner top claw tightly propped against the cloth roll is increased, the requirement on the inner diameter of the paper tube is reduced, and even if the cloth roll with the larger size is used, the cloth roll can be cut by a machine; meanwhile, the clamping arms clamp the periphery of the cloth roll, and the pushing claws push against the inner peripheral wall of the paper tube of the cloth roll, so that poor cutting effect caused by deformation of the paper tube during cutting can be reduced;
3. the cloth is saved, the loss of the tail end of the cloth roll is reduced, and the yield of the strip cutting and bundling machine is improved;
4. the number of manual operation steps is reduced, and the production safety is improved.
