A semi-automatic bone sawing machine

Abstract

The invention relates to the technical field of electric tools, and discloses a semi-automatic bone sawing machine, which includes a fixed frame, a transmission wheel and a saw blade. A transmission box is fixedly installed on the back of the fixed frame. A tension box is fixedly installed on the front of the frame, and a limiting plate is movably installed on the left side of the middle part of the fixing frame, and a threaded feed handle is movably connected to the left middle part of the limiting plate. Through the setting of the transmission box and the tension box, the saw blade is placed vertically and horizontally and the cutting mouth is upward, and the debris generated by cutting with the bone directly hits the panel of the transmission box or the tension box, and the top is covered with each bone. It is shielded to reduce the flying of debris and reduce the difficulty of cleaning, and through the setting of the movable drive pulley, the distance between the saw blades on both sides of the drive wheel can be adjusted, so that the cutting length of the bone between the saw blades can be determined. Carry out two cuts at the same time to increase cutting efficiency.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a semi-automatic bone sawing machine. Background technique [0002] The bone sawing machine is used for cutting all kinds of small and medium-sized animal bones, frozen meat, fish bones, frozen fish, and ice cubes. The cutting principle is as follows: Figure 7 As shown, the saw blade 3 is driven by the transmission wheel 2 with a larger diameter, and the clockwise transmission is carried out. The staff will need to fix the bones to be cut on the platform of the frame 1, slowly pass through the saw blade 3 independently located outside the part, and be cut by the saw blade 3 , forming small pieces, but there are some deficiencies in the current bone sawing machine, as follows: [0003] The saw blade 3 is perpendicular to the fixed frame 1. When cutting the bone, the safety distance between the staff and the saw blade 3 is small, and the bone needs to be pushed to contact t...

Problems solved by technology

[0003] The saw blade 3 is perpendicular to the fixed frame 1. When cutting the bone, the safety distance between the staff and the saw blade 3 is small, and the bone needs to be pushed to contact the saw blade 3. In the process of cutting the bone, once the staff makes a mistake, the hand and The front contact of the saw blade 3 is very easy to be cut, which poses a threat to the safety of the staff. At the same time, when the saw blade 3 cuts the bone, the bone is pushed horizontally to the saw blade 3, and the moment of contact with the saw blade 3, a large contact with the saw blade 3 is generated. The reverse tangential force with the opposite transmission direction causes the saw blade 3 to vibrate. The light one causes the saw teeth on the saw blade 3 to wear out, and the severe one causes the saw blade 3 to break. At the same time, when the saw blade 3 cuts the bone, it carries the cutting debris and hits the bone. On the platform of the fixed frame 1, debris will fly, which will easily affect the staff and reduce the cutting rate
