A separation clamping type pre-coated steel plate cutting mechanism

Abstract

The present invention discloses a separation clamping type pre-coated steel plate cutting mechanism, comprising a processing table, a cutting assembly, a separation clamping assembly, and a transmission assembly; the present invention drives the cutting blade to cut downwards through a telescopic shaft, and at this time the telescopic shaft drives the floating adjustment plate to move upwards through the transmission assembly, thereby driving the upper driving roller to move upward synchronously, so that the upper driving roller is separated from the pre-coated steel plate upwards, and the pre-coated steel plate loses the driving force of the upper driving roller and stops rotating. At this time, the pre-coated steel plate will not be clamped by the upper driving roller and the lower supporting roller. When the telescopic shaft drives the cutting blade to cut downwards, the pre-coated steel plate on the side of the cutting port is squeezed and no squeezing marks are generated with the upper driving roller and the lower supporting roller. The structural design is ingenious.

Description

Technical Field

[0001] The invention relates to a separation clamping type pre-coated steel plate cutting mechanism. Background Art

[0002] Pre-coated steel sheet is made of metal coil as the base material, and various organic coatings or plastic films are coated or laminated on the surface. The coated steel sheet is light, beautiful and has good corrosion resistance. It can be directly processed. It provides a new type of raw material for the construction industry, shipbuilding industry, vehicle manufacturing industry, home appliance industry, electrical industry, etc. After the surface coating treatment, the pre-coated steel sheet will be curled and placed in a coil. The coil of the pre-coated steel sheet is generally cut by a shearing machine when in use. The current shearing machine generally clamps and rotates two rollers to convey the coil of the pre-coated steel sheet forward. The motor drives the roller to rotate and transport periodically. After transporting a section of the coil, the cutting knife stops cutting, thus forming a continuous cutting operation. However, when the cutting knife cuts downward, the pre-coated steel plates on both sides of the cutting mouth will be squeezed outward, causing the coil to be squeezed outward. Since the coil of the pre-coated steel plate is clamped by two rollers, the part of the pre-coated steel plate clamped by the two rollers is squeezed and rubbed against the rollers to cause surface scratches, which damages the surface of the pre-coated steel plate. In this way, the pre-coated steel plate needs to be repaired later, resulting in increased production costs for the company. Summary of the invention
