Safety bench saw based on flywheel limiting

Abstract

The invention belongs to the technical field of bench saws, and particularly relates to a safety bench saw based on flywheel limiting. The bench saw comprises a bench saw shell, an annular saw blade,a mechanism cavity, a fixed plate, a first arc guide rail, a first driven wheel, an arc limiting plate, a flywheel, a transmission gear, a second driven wheel, a motor, a drive wheel and the like; when a user touches the high-speed-rotating annular saw blade due to sudden accidents, the motor is stopped, a coil is instantly powered on, under the electromagnetic induction effect, a ladder type block is instantly inserted into a corresponding ladder cut opening, the flywheel drives the arc limiting plate to do arc motion around the axis of the flywheel, clamping teeth on the arc limiting plateand the sawteeth on the annular saw blade carry out limiting finally, the annular saw blade is instantly stopped, and safety of the user is protected; in addition, the first driven wheel moves downwards, a first belt gradually becomes loose, the possibility that the first driven wheel is subject to transmission, and the annular saw blade still rotates is avoided, and safety of the user is furtherprotected.

Description

technical field [0001] The invention belongs to the technical field of table saws, in particular to a safety table saw based on flywheel limit. Background technique [0002] At present, for the traditional table saw, the user needs to use the table saw carefully to cut the object to be cut; however, in the process of using the table saw, the hand of the user may still be cut due to accidents. In order to prevent the user from being cut by accident, there is a hot dog saw specially designed to protect the user in the current technology. The saw blade of the hot dog saw can stop in a very short time in an emergency , so as to prevent the user from being cut; the saw blade of the traditional hot dog saw stops in a very short time because of the instantaneous explosion of gunpowder. The normal use of the hot dog saw; in order to avoid such a complicated process of disassembling the machine and refilling the gunpowder, it is necessary to design a safe table saw that does not req...

[0002] At present, for the traditional table saw, the user needs to be careful to use the table saw to cut the object to be cut; but in the process of using it, the user may still cut his hand due to accidents

In order to prevent the user from being cut by accident, there is a hot dog saw specially designed to protect the user in the current technology. The saw blade of the hot dog saw can stop in a very short time in an emergency , so as to prevent the user from being cut; the saw blade of the traditional hot dog saw stops in a very short time because of the instantaneous explosion of gunpowder. The normal use of the hot dog saw; in order to avoid this complicated process of disassembling the machine and refilling the gunpowder, it is necessary to design a safe table saw that does not require gunpowder for an instant explosive impact, and can also ensure that the saw blade stops rotating instantly.
