Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a meat thread cutting machine that mechanically cuts flat pieces of meat into approximately constant widths.

Conventional Technology Conventionally, meat is mechanically cut into desired shapes by using a meat slicer to slice meat into thin slices and by using a cube cutter to cut meat into cubes. However, the thin strips of meat most often used in Chinese cuisine had to be cut by hand using a knife. Therefore, the present applicant first installed a pair of rotating shafts that rotate inwardly to each other horizontally in a hollow body that opens upwardly and downwardly, and attached a disk having an appropriate thickness and diameter to the rotating shafts. At the same time, the cutting edge of the blade fitted on one rotating shaft slides against the cutting edge of the blade fitted on the other rotating shaft, alternately. Jitsuganaki developed a meat thread cutter that was able to mechanically cut meat with a width of around 5 mm by fitting it between the two and fixing it so that it rotated inwardly.
It was proposed as No. 59-34403.

Problems to be Solved by the Inventor As a result of cutting meat using the thread cutting machine of the earlier application, the inventors of the present invention were able to obtain thread-trimmed meat smoothly at the beginning of use, but over a long period of time or repeatedly. Depending on the use and the quality of the material, fat may adhere or accumulate on the side of the blade, reducing its sharpness, or the lines of the meat may become entangled with the collar fitted between the blades. It has been found that there is a drawback that the cut portion of the thread cutter must be frequently cleaned because it becomes difficult for the cut pieces of meat to be discharged outside the machine. The thread cutting machine of the above-mentioned prior application was also provided with a pair of comb-shaped guide plates whose tips were inserted between the blades fixed on the respective rotating shafts. However, in the guide plate of the conventional machine, the proximal end is pivoted to a support shaft suspended horizontally above the rotating shaft just below the opening into which the piece of material is inserted into the machine body, and the comb tooth part is shaped like a curtain. Since it was installed facing downward along the direction of insertion, it had the function of guiding the material to the cutting position, but it also prevented fat and meat from adhering to rotating parts such as the blade and collar and trying to rotate together. It was found that it does not have a scraper-like function to scrape off streaks, and that this causes the problems described above.

As a means to solve the problem, the present invention proposes a pair of rotating shafts each having a thread cutting blade fixed thereto, and a slit with a width approximately equal to the blade thickness of the blades along the axis direction of each shaft. and comb-teeth portions are formed alternately and continuously, and the comb-teeth portions are interposed between the blades coaxially attached from the inside of the rotating shaft and extended upwardly along the outer shape of each blade. To provide a meat thread cutting machine equipped with a pair of comb-shaped guide plates.

Function As described above, the thread cutting machine of the present invention has a comb-shaped guide plate interposed between each blade inside the rotating shaft so that the comb-shaped guide plate faces upward along the outer shape of the blades. Since it is provided, fat and streaks attached to the rotating parts can be scraped off like a scraper.

Embodiments Examples of the present invention will be described below with reference to the drawings.

In the figure, 1 is a hollow body with a known drive mechanism 2 made of gears or the like at one end (left side in FIG. A pair of rotating shafts that rotate inwardly within the body 1 and have a hexagonal cross section and are horizontally mounted parallel to each other; 6 indicates this rotating shaft 5;
It is a large number of disc-shaped blades of the same shape having appropriate thickness and diameter, which are fitted into the blades a and 5b, respectively. Each blade above 6
As shown in FIG. 2, an octagon whose corners are formed into circular arcs is used, and the collars 7 of the same thickness are fitted to the respective rotating shafts 5a and 5b, and one The blade 6 fitted on the rotating shaft 5a of
The cutting edge 6' is fitted between the blades 6 fitted on the other rotating shaft 5b, and the cutting edges 3', which are fitted alternately from the left and right, slide their corner edges against each other and move inside. It is installed so that it can be rotated in any direction.
8 is a cam plate provided by fitting the same shape as the blade 6 to both ends of each rotating shaft 5a, 5b, and each of the blades 6, collar 7, and cam plate 8 are:
The rotary shafts 5a and 5b are fixed on their respective shafts at a predetermined distance by fastening a nut 10 to a disc spring 9 fitted to the tips (on the right side in FIG. 1). 11 is a bearing plate that supports the tips of the rotating shafts 5a and 5b; 12
is a connecting rod that holds the bearing plate 11 to the fuselage 1.
Reference numeral 13 denotes a pair of comb-shaped guide plates provided below each of the pair of rotating shafts 5a and 5b. This guide plate 13 has slit portions a and comb teeth portions b, each having a width approximately equal to the blade thickness of the blade 6, alternately and continuously formed.
It intervenes between each blade 6 coaxially attached from the inside of 5b and extends upward along the outer shape of the blade 6. Reference numeral 14 denotes an elevating rod with a restoring spring 16 that fixes both ends of the lower part of the guide plate 13 and fits into vertical holes 15 provided in the fuselage 1 and the bearing plate 11, respectively. is biased and contacts the cam plate 8 from below, and the rotating shaft 5
The guide plate 13 is vibrated up and down with the rotation of a and 5b.

In this thread cutting machine configured as described above, when a flat piece of meat is inserted through the upper opening 3, its lower edge is guided by the tip of the comb tooth part b until it reaches the rotating position of the blade 6, where it slides against each other. The cutting edge 6' cuts the thread into a thin thread equal to the thickness of the blade, and the lower opening 4
is discharged from. The fat or meat streaks attached to the side surface and outer circumferential surface of the blade 6 during the above-mentioned cutting are scraped off from the adhesion surface like a scraper by passing through the slit part a, which has a width approximately equal to the blade thickness, in the inner direction. It is discharged together with

Effects of the invention According to the present invention, in which a comb-shaped guide plate is provided upward as described above, fat or meat streaks formed on the side surface or outer circumferential surface of the blade during cutting can be prevented by changing the rotation angle of the blade. Before changing from the inner circumference to the outer circumference, it passes through a slit section fixedly provided along the outer shape of the blade with a width almost equal to the thickness of the blade, so the comb tooth section can scrape the attachment surface like a scraper. be scraped off. Therefore, there is no accumulation of deposits on the blade etc.
It has the practical effect of being able to be used continuously for a relatively long time and greatly reducing the frequency of cleaning the rotating parts.
