Blade grinding machine steel belt unwinding temporary-storage device

Abstract

The invention discloses a blade grinding machine steel belt unwinding temporary-storage device, and belongs to the technical field of cutter production equipment. The blade grinding machine steel beltunwinding temporary-storage device comprises a temporary-storage table, a traction machine and a butt joint machine, wherein the temporary-storage table comprises a base, a fixed disc set, a movabledisc set and a driving mechanism; and one end of a steel belt is located in the traction machine, the other end of the steel belt is located in the butt joint machine, and the middle part of the steelbelt is wound around the fixed disc and the movable disc for temporary storage. When the blade steel belt is about to finish unwinding and needs to be in butt joint with a new blade steel belt coil,the driving mechanism acts to enable the movable disc set to slowly move towards the fixed disc set, the traction speed of the traction machine is matched well, the steel belt is enabled not to move in the butt joint machine, and at the moment, the problem that positioning is inaccurate due to the inertia generated when the steel belt stops running is also solved; after the butt joint machine actsto enable the last steel belt coil about to finish unwinding to be in butt join with the new steel belt coil, the driving mechanism acts to enable the movable disc set to move in the direction away from the fixed disc set to reach a designated position, and then the temporary-storage of blade grinding machine steel belt unwinding can be completed; and the unwinding temporary-storage device is quite convenient to assemble, reliable in operation and capable of improving the working efficiency.

Description

technical field [0001] The invention relates to the technical field of cutting tool production equipment, in particular to a discharge buffer device for a steel belt of a blade grinder. Background technique [0002] Steel strip, also known as steel strip, is actually a thin, narrow, long length of steel plate, usually supplied in coils. Compared with steel plates, it has the advantages of high dimensional accuracy, good surface quality and easy use. Widely used in the production of welded steel pipes, cold-formed steel blanks, used to manufacture bicycle frames, rims, clamps, washers, springs, cable armor, saw blades, blades and baled iron sheets, etc. [0003] Wherein, the method of producing blades from a steel strip is as follows: the blade steel strip is cut into discrete blanks, each discrete blank has an elongated edge and an elongated support portion, the elongated support portion is generally transverse to the elongated edge on a pair of sides extending between the...

AI Technical Summary

Problems solved by technology

This production method leads to the interruption of the continuity of production, the reduction of production efficiency, and the following defects:

[0006] (1) When the steel belt needs to stop running, due to inertia, the steel belt often travels for a certain distance, causing the steel belt at the end of the material to run out of the docking device, resulting in the need to manually pull the steel belt back to the docking device;

[0007] (2) When a steel strip is processed and a new steel strip needs to be connected, the operation must be stopped, which seriously affects the efficiency

However, in this operation process, because the pressure roller is always pressed tightly on the traction roller, affected by the inertia when the machine stops, a section of the tail end of the steel strip will be connected. After the worker changes the roll, he must start from the next coil The welding with the previous steel strip can only be achieved by pulling out a section from the top. It is still laborious and time-consuming to manually pull the steel strip out of the strip.
