Description

Frozen meat cutting machine

The present invention relates to a frozen meat cutter, and more particularly, to a frozen meat cutter in which the number of parts is minimized by improving the structure of a driving part.

Recently, as the consumption of meat has been explosively increased, various devices for processing meat have been developed. For example, it is an apparatus etc. which cut meat into slices.

In general, when cutting meat using a rotating cutter, if the meat is refrigerated meat, cutting must be done while rotating the cutter at high speed. to be.

On the other hand, if the meat is frozen meat, the rotation speed of the cutter should be maintained at a low speed, because the blade of the cutter is abraded by friction with the hard surface of the meat. There is a limit to cutting. In addition, when the blade is worn, a phenomenon in which the blade is thrown out during cutting occurs. And, since the tendons of the meat are not cut, the rotation speed of the cutter must be lowered to a low speed.

In the prior art, in order to solve the above problems, the main body 10 and; and a frozen meat supply unit 20 and a frozen meat slice unit 30 arranged in a line on the main body for supplying frozen meat and slicing the frozen meat, and the frozen meat supply unit, the supply die 21, frozen meat from one side of the supply die a fork 22 for fixing the fork, and a transfer means 23 for transferring the fork and frozen meat forked by the fork to the frozen meat slice unit, wherein the frozen meat slice unit supports and slices the frozen meat supplied from the frozen meat supply unit A transfer conveyor 31 for transferring the pieces, a plate-shaped knife 32 for slicing frozen meat supplied from the frozen meat supply unit to a predetermined thickness, and a driving means for the knife, wherein the driving means is a driving motor 41, the A drive cam (43) that rotates by a drive motor, and a central part is coupled to one side in the axial direction of the drive shaft, while the knife is connected to the opposite side of the sector-shaped cam part through a bearing and a shaft to drive the knife in a circular motion ( 45), a weight 47 having a sector-shaped cross-section coupled to the other side of the drive shaft in the axial direction, wherein the driving cam has a sector-shaped cam part and a straight-line type extending equally throughout while having a smaller cross-sectional area than the cam part at the end of the cam part is composed of a connection part of the cam part and has a symmetrical structure with respect to the center line of the connection part, while a shaft hole to which one longitudinal side of the driving shaft is connected is formed in the center, and a knife connected to the knife at the edge of the connection part A connection hole is formed, and the knife is connected to the knife connection hole of the drive cam via a shaft, and a frozen meat high-speed cutter is disclosed that cuts the frozen meat while drawing a circular trajectory of a certain shape through the drive cam and the shaft. .

However, the above frozen meat high-speed cutting machine has a problem in that the structure of the driving part is inevitably complicated because a driving shaft, a driven shaft, a belt and a weight are necessarily required to rotate a pair of driving cams that drive the knife.

That is, since a pair of drive cams for driving the knife are each connected to the drive shaft and the driven shaft, a belt for rotating the drive shaft and the driven shaft in conjunction with each other is absolutely necessary.

In addition, a weight for adjusting the balance between the driving cam and the knife is necessary to the other side of the driving shaft and the driven shaft to which the driving cam is connected.

In addition, as the belt and the weight are disposed on the other side of the drive shaft and the driven shaft to which the drive cam is connected, a space for arranging them must be prepared, so that the volume of the high-speed cutter is inevitably increased.

Therefore, as the structure of the driving means for driving the knife becomes complicated, when a problem occurs in any one of the structures, the cutting machine cannot be driven smoothly, and if a problem occurs in the balance of the knife, fatal safety cause accidents
