Description

Technical Field

[0001] The utility model relates to the technical field of bone sawing machines, in particular to a slaughter bone sawing machine with replaceable saw blades. Background Art

[0002] Bone saws are mostly used in slaughterhouses for cutting and processing larger pieces of animal meat, or they can also be used for cutting frozen foods. They are also very practical for cutting bones of cattle, sheep and pigs.

[0003] In the existing technology, the surface cleaning of meat does not involve a disinfection process. The food processing industry should pay more attention to sanitary conditions, and disinfection should be carried out even more for frozen foods.

[0004] To overcome these drawbacks, the prior art (Chinese patent application number: CN218551134U, filed November 16, 2022) discloses a butcher's bone saw, which belongs to the technical field of bone saws. This utility model includes a bone saw housing, with a transmission saw cylinder movably mounted at both the upper and lower ends of the housing. A saw blade is sheathed on the surface of the transmission saw cylinder, and a motor is fixedly connected to the back of the housing. The utility model sets a disinfection and cleaning mechanism, and uses a water pump and a fan to transport high-temperature hot water and steam to both sides of the saw blade for high-temperature cleaning and sterilization. Due to the high temperature, it can not only sterilize, but also effectively remove saw bone waste attached to the surface of the saw blade. After disinfection, the scraper block is used to scrape off the residual moisture on the surface of the saw blade, which is beneficial to the operation of the saw blade. Afterwards, an electric heating wire and a first ultraviolet sterilization lamp are set to continuously sterilize the saw blade in a relatively closed environment, thereby achieving the purpose of high-efficiency sterilization. Moreover, the saw blade can be continuously disinfected during sterilization without stopping the machine. At the same time, the materials used for disinfection are environmentally friendly and non-toxic, and have the effect of environmentally friendly disinfection.

[0005] Although the existing technology can solve the above problems, it does not have a good fixing design for the meat or bones that need to be cut. The existing bone fixing design is too simple, and it is easy to cause the cutting size to be uneven or even fall due to slipping of the hand or loose fixation. Moreover, the fixing of the saw blade in the existing technology is too simple, which may cause it to loosen after long-term use. Utility Model Content

[0008] A sliding groove is installed above the operating table, and a transmission fixing mechanism for fixing and clamping the bones is installed above the sliding groove.

[0009] Furthermore, the transmission fixing mechanism includes a second bracket, and a placement plate is installed on the upper surface of the second bracket, and a push rod is installed inside the placement plate, an elastic wire group is installed on the surface of the push rod, and the end of the elastic wire group is installed on the surface of the second bracket, the second bracket is fixedly connected to the end of the elastic wire group, and the lower surface of the push rod is installed to slide back and forth along the inner surface of the placement plate, a fifth inner groove is opened on the side of the second bracket, and an upper fixing plate is installed inside the fifth inner groove.

[0010] Furthermore, a fixing block is installed on the upper surface of the upper fixed plate, and a rotating fixing rod is installed inside the fixing block. A seventh inner groove is provided on the upper surface of the second bracket, and the rotating fixing rod passes through the seventh inner groove. A sixth inner groove is provided on the left side of the upper fixed plate, and the push rod passes through the sixth inner groove. A second spring is installed below the upper fixed plate, and the lower surface of the second spring is fixedly installed above the second bracket.

[0011] Furthermore, the surface of the nested rod contacts the interior of the first spring to form an elastic structure, and the outer surface of the nested rod contacts the interior of the third inner groove to form a sliding structure, and the third inner groove is symmetrically opened in two groups about the center line of the saw blade mounting fixture.

[0012] Furthermore, the upper and lower ends of the engaging handle contact with the inner surface of the fourth inner groove to form a sliding structure, and the inner surface of the mounting groove contacts with the inner surface of the saw blade mounting fixture to form a sliding structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: after the saw blade and the saw blade fixing plate are fixed by bolts, the saw blade fixing plate is pushed forward along the hollow position of the saw blade mounting fixture. During the pushing process, the mounting groove and the inner part of the saw blade mounting fixture are nested and installed. As the saw blade fixing plate is continuously pushed forward, the two side surfaces of the saw blade fixing plate contact the nesting rod. Since the nesting rod is designed to be inclined, the nesting rod presses the first spring installed on the outer surface to start contracting. After reaching the second inner groove, the first spring releases its elasticity to push the nesting rod into the second inner groove. Such a design utilizes the elasticity of the first spring to make the installation simpler and more secure, thereby completing the secondary fixation of the saw blade.

[0016] Furthermore, after placing the bone to be cut on the placement plate, the upper fixing plate is pushed downward, and the second spring is continuously pressed downward during the sliding process. After the rotating fixing rod passes through the seventh inner groove and reaches the appropriate position, the rotating fixing rod is rotated to fix the upper fixing plate. This design strengthens the clamping of the meat to be cut and simplifies the operation.

[0017] Furthermore, while the upper fixing plate slides downward, the push rod installed inside the sixth inner groove on the side is pushed forward by the upper fixing plate due to its inclined design and slides forward along the placement plate, completing the secondary fixation of the bones that need to be processed inside. This design fixes both the top and sides of the bones, completing the secondary fixation effect and making the processing process more efficient. BRIEF DESCRIPTION OF THE DRAWINGS
