Mechanical clamping device of coiled wide-width material

Abstract

The invention provides a mechanical clamping device of a coiled wide-width material. The device is characterized by comprising a power side clamping device, a driven side clamping device and a papertube; the power side clamping device comprises a body I, a sliding sleeve and a protruded key; the driven side clamping device comprises a body II, the sliding sleeve and the protruded key; the papertube pushes the sliding sleeve to move towards the body I and the body II, and the sliding sleeve drives the protruded key to move; and the protruded key extends out of the outer surface of the sliding sleeve to be in contact with the inner surface of the paper tube to realize fixing of the paper tube in a tensioning mode. According to the power side clamping device, the driven side clamping device, a cooperative mode between the sliding sleeve, the protruded key, the body I and the body II is adopted, the axial-direction fixing of the paper tube, through the power side clamping device and thedriven side clamping device, is changed into the radial-direction fixing, so that the paper tube end part is prevented from cracking caused by the fact that the paper tube end part is clamped throughthe axial force, under the condition that the paper tube is fixedly clamped, the risk of cracking of the paper tube end part is reduced, the winding precision is improved, and the winding quality isensured.

Description

technical field [0001] The invention relates to the technical field of processing roll-shaped wide-width materials, in particular to a mechanical clamping device for roll-shaped wide-width materials. Background technique [0002] In the processing field of roll-shaped wide-width materials, it is usually necessary to unwind, process, and then rewind the roll-shaped parent roll material. During the process of unwinding the parent roll and rewinding the product, the paper tube must Fixing, there are two traditional ways to fix the paper tube, one is to penetrate the inside of the paper tube through the mandrel, and the mandrel expands to fix the inner diameter of the paper tube, thereby fixing the paper roll, and the other is directly on the paper tube The end of the paper tube is fixed by fixing the end of the paper tube. Usually, a plugging device can only meet one fixing method. For example, the patent "CN204124875" discloses a clamp for unwinding of a layering machine Asse...

[0002] In the processing field of roll-shaped wide-width materials, it is usually necessary to unwind, process, and then rewind the roll-shaped parent roll material. During the process of unwinding the parent roll and rewinding the product, the paper tube must Fixing, there are two traditional ways to fix the paper tube, one is to penetrate the inside of the paper tube through the mandrel, and the mandrel expands to fix the inner diameter of the paper tube, thereby fixing the paper roll, and the other is directly on the paper tube The end of the paper tube is fixed by fixing the end of the paper tube. Usually, a plugging device can only meet one fixing method. For example, the patent "CN204124875" discloses a clamp for unwinding of a layering machine Assemblies, including the driving side clamp and the driven side clamp, the driving side clamp is mainly assembled by the driving side 6-inch collet and the driving side 3-inch collet, the driven side clamp is mainly composed of the driven side 6-inch collet and the driven Assembled with the 3-inch collet on the side, the 6-inch collet on the driving side and the 6-inch collet on the driven side have 6-inch holes for installing the 6-inch paper roll, the 3-inch collet on the driving side and the 3-inch collet on the driven side The chuck is located between the 6-inch chuck on the driving side and the 6-inch chuck on the driven side. The clamp assembly realizes the clamping of 3-inch or 6-inch paper rolls through tapered holes, and can only be used for 3-inch or 6-inch paper rolls. Since the overall weight of the wide-width mother roll is relatively heavy, only the end face of the paper tube end is fixed by axial force, which will easily cause the end of the paper tube to break and affect the clamping and installation of the paper tube. The quality of the finished product will cause damage and scrap of the paper tube, reduce the reuse rate of the paper tube, increase the production cost of the enterprise, and when it is necessary to use a mandrel to fix the paper tube, a new clamping device needs to be replaced, and the auxiliary man-hour for replacement is relatively long , the operation is cumbersome, which seriously affects the production efficiency of the enterprise
