Anti-hand-cutting bench saw

Abstract

The invention belongs to the technical field of bench saws and especially relates to an anti-hand-cutting bench saw. The bench saw comprises a bench saw mounting housing, a saw blade, a drive motor, asecond belt and a gunpowder drive structure. When people use the bench saw designed by the invention, under normal working, the drive motor is controlled to work; the drive motor works to make the motor output shaft rotate; when the output shaft of the motor rotates, a support drive shaft is driven to rotate through the second drive belt drives; the support drive shaft rotates to drive the saw blade to rotate; the saw blade works. During the work, if people accidentally touch the saw blade during use, the relatively large capacitance inside the human body will change the weak power on the sawblade, which triggers the electrical signal on the saw blade; the electrical signal triggers the gunpowder drive structure; after the gunpowder drive structure is detonated, the gunpowder drive structure pushes the trigger drive plate toward the side where the saw blade is mounted; the movement of the trigger drive plate will speed up the movement of the saw blade into the table saw mounting housing to prevent fingers from being cut.

Description

Technical field [0001] The invention belongs to the technical field of table saws, and particularly relates to an anti-cutting hand table saw. Background technique [0002] The table saw is the center of most woodworking houses and is a must-have operating equipment for the woodworking industry. But if used improperly, the table saw will be very dangerous. In the production operations of the woodworking industry, external injuries are not uncommon, and the fingers bear the brunt. Almost all woodworkers’ fingers have been injured more or less, and some have been cut off. It can be said that the table saw has brought great convenience to our wood industry production, but at the same time it has also brought unfortunate damage. The existing mechanical protection table saw in the market can also protect the human body, but it uses the method of mechanical braking to realize the stop of the table saw. The design, manufacture and processing of the mechanical braking system of the me...

AI Technical Summary

Problems solved by technology

The existing type of mechanical protection table saw in the market can also protect the human body, but it uses mechanical braking to stop the table saw. The design, manufacture and processing of the mechanical protection table saw mechanical braking system After the table saw is mechanically braked, the impact on the table saw blade is greater, causing the table saw blade to be worn or damaged

The table saw blade needs to be replaced after each braking impact, resulting in a waste of production and an increase in the cost of use

At the same time, it takes a certain amount of time to replace the table saw blade each time, thereby reducing production efficiency.
