Hand injury prevention device for wood furniture processing cutting machine

Abstract

The invention discloses a hand injury prevention device for a wood furniture processing cutting machine. The hand injury prevention device comprises a cutting machine body, wherein an injury prevention pushing assembly, a saw disc and a backing plate are arranged on the surface of the top of the cutting machine body, the injury prevention pushing assembly comprises a sector plate and a push rod, and the push rod is fixed to the surface of one side of the sector plate; and a T-shaped sliding groove is formed in the top of the cutting machine body, a T-shaped sliding block is arranged in the T-shaped sliding groove, and the top end of the T-shaped sliding block protrudes out of the top surface of the cutting machine body. Through arrangement of a rectangular groove, a rectangular inner block, a rectangular rod, insertion rods, insertion grooves, spring grooves, a semicircular clamping block and semicircular clamping grooves, when an operator pushes the sector plate, even if a handle is pushed by the hand of the operator to rotate, the situation that a fastening screw sleeve rotates around is avoided, the fastening screw sleeve can play a role in fastening and limiting the sector plate all the time, and the angle of the sector plate is not prone to change in the pushing process.

Description

technical field [0001] The invention belongs to the technical field of furniture cutting machines, and in particular relates to a hand injury prevention device for wooden furniture processing and cutting machines. Background technique [0002] During the processing of wooden furniture, a desktop cutting machine is needed. In order to allow the operator to keep a certain safe distance between the hand and the saw disc when pushing the board for cutting, a protective guard will be set on the top. The anti-injury propulsion component enables the operator to push the plate through the anti-injury propulsion component instead of directly pushing the plate by hand, so as to prevent the operator's hand from being injured and avoid the occurrence of safety accidents. [0003] The existing anti-injury propulsion assembly consists of a T-shaped slider, a fan-shaped plate and a push rod on the side of the fan-shaped plate. When it is necessary to adjust the angle of the fan-shaped plat...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a hand injury prevention device for a wooden furniture processing and cutting machine to solve the problem that the existing injury prevention propulsion assembly proposed in the above-mentioned background technology is composed of a T-shaped slider, a fan-shaped plate and a push rod on the side of the fan-shaped plate. , when it is necessary to adjust the angle of the fan-shaped board and the push rod, the handle on the top of the fan-shaped board can be rotated and loosened, so that the fan-shaped board can be rotated under the action of the rotating shaft to adjust the angle, and after the adjustment is completed, the handle can be rotated and tightened Fixed, but during the subsequent push of the fan-shaped board, the operator will press the fan-shaped board with the palm and push the handle with the thumb, which will easily cause the handle to turn and loosen, resulting in the angle of the fan-shaped board. Changes occur and affect the subsequent cutting angle of the plate, and there are certain disadvantages
