[0027] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 7 :

[0028] A bone sawing machine with automatic material clamping comprises a base 1, a saw frame 2 and a feeding mechanism 3 are arranged above the base 1, a driving wheel 20 rotated by a driving motor is arranged in the saw frame 2, a driven wheel 22 which rotates synchronously through a ring saw blade 21 is arranged on one side of the driving wheel 20, the feeding mechanism 3 comprises a material pressing base 30 arranged on a sliding group 4, a plurality of longitudinally arranged cylinders 31 are fixed above the material pressing base 30, a side shell plate 32 fixed to the material pressing base 30 is arranged on one side of the plurality of cylinders 31, a side long hole 320 corresponding to each cylinder 31 is opened on the side shell plate 32, a connecting rod 33 which slides up and down along the side long hole 320 is fixed on the piston rod 310 of the cylinder 31, and a pressing block 34 is fixed on the end of the connecting rod 33.

[0029] like Figure 2 As shown, the cutting part of the bone saw machine is carried out at the saw frame 2, the driving wheel is driven by a driving motor on one side, and the driven wheel is driven to rotate through the ring saw blade 21, and the driven wheel 22 also allows the ring saw blade 21 to be tightened during the movement, so that the saw blade is more stable and does not shake when cutting.

[0030] During cutting, the sliding group 4 performs continuous cutting operation on the clamped material.

[0031] Material clamping process:

[0032] like Figure 3 and Figure 4As shown, before cutting the material, it needs to be clamped and fixed to achieve uniform cutting. The piston rods of all cylinders are lifted up in advance to create the largest gap between the pressing block and the pressing base, which is convenient for the end of the material to be put in. After the material is put in, the piston rods of all cylinders move downward, driving several pressing blocks to press down, thereby fixing the end, so that the sliding group 4 drives the movement of the pressing base, and the material always remains stable.

[0033] In the above-mentioned pressing process of several pressing blocks, the material itself has a certain volume. In the actual pressing process, the pressing blocks under force on the surface of the material will have different degrees of pressing distance. That is, the downward pressure of the cylinder piston rod will not cause significant damage to the end of the material, but it is limited to fix the frozen food, which is convenient for squeezing and fixing the end.

[0034] Preferably, a lower rack 300 extends upward from one side of the pressing base 30 , and a plurality of engaging teeth 340 are provided at the bottom of the pressing block 34 .

[0035] In order to prevent the end of the material from being separated during the pressing process, the lower rack 300 and the engaging teeth 340 are provided to enhance the squeezing and tightening effect of the end.

[0036] Preferably, the connecting rod 33 passes through the side long hole 320, and the connecting rod 33 extends out of the side long hole 320 to fix the pressing block 34. In the above structure, the connecting rod 33 extends out of the side long hole 320 to prevent the material from contacting the cylinder transmission part, prevent the transmission from being blocked, and ensure long-term clamping operation.

[0037] Preferably, at least two nuts 330 arranged longitudinally are fixed to the front side of the connecting rod 33 extending out of the side long hole 320 , and a plurality of mounting holes 341 corresponding to the nuts 330 are longitudinally opened on the pressing block 34 .

[0038] In the actual adjustment process, due to the certain differences in the heights of the ends of different materials, the height position of the pressing block is adjusted, and then the bolts are passed through the mounting holes of the pressing block and threadedly fixed with nuts to provide different height ranges for clamping.

[0039] Preferably, the press base 30 is provided with a guide support rod 35 for the longitudinal sliding of the connecting rod 33, and a limit frame 36 is fixed above the cylinder seat of the cylinders 31. The guide support rod 35 is used to provide abutment when the connecting rod moves up and down, so that it is more stable when sliding up and down; the limit frame 36 allows the cylinder 31 to maintain the stability of the cylinder seat during the up and down movement of the piston rod, so that the pressure block is not likely to fail to press the material.

[0040] Preferably, the sliding group 4 includes a sliding table 40 fixed on the base 1, a lower slide plate 41 is slidably provided above the sliding table 40 through front and rear slide rails, an upper slide plate 42 is fixed above the lower slide plate 41, and the pressing base 30 is slidably provided on the upper slide plate 42 through left and right slide rails. The cross-section of the pressing base 30 is an inverted "concave" shape, and a main slide plate 43 is inserted into the pressing base 30 to fix the upper slide plate 42.

[0041] like Figure 6 and Figure 7 As shown, during the sliding process, the sliding group 4 drives the lower slide plate 41 to slide forward and backward through the front and rear slide rails, and drives the pressing base 30 to slide left and right through the left and right slide rails. Since the cross-section of the pressing base 30 is set to an inverted "concave" shape, it is convenient to install and fix the main slide plate 43, that is, in the process of pushing the material, the main slide plate 43 remains stationary, allowing the material to slide on the main slide plate 43.

[0042] Preferably, a horizontal conveyor belt 23 for transporting in the front-to-back direction is provided between the driving wheel 20 and the driven wheel 22 , the ring saw blade 21 is located on one side of the conveyor belt 23 , and the feeding mechanism 3 is located on the other side of the ring saw blade 21 .

[0043] In the above embodiment, the saw frame is formed into a C shape, so that a section of the ring saw blade can be conveniently cut, and the continuously working conveyor belt 23 can conveniently transport the cut materials, thereby improving work efficiency.

[0044] Working principle:

[0045] The bone sawing machine provided by the utility model relies on arranging a plurality of cylinders in the feeding mechanism, and arranging a pressing block capable of pressing down the end of the material at the piston rod of the cylinder, so as to clamp the material and make it more stable and not easy to fall off during the cutting process.

[0046] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
