Description

Technical Field

[0001] This utility model relates to the field of pig head cutting technology, and in particular to a special-shaped knife assembly device for positioning and cutting pig heads. Background Technology

[0002] In the meat processing industry, pig heads, due to their complex structure and densely packed bones and muscles, often require meticulous cutting during post-slaughter deboning. To improve efficiency and product uniformity, the industry commonly employs various manual or semi-automatic auxiliary devices to help locate and separate the pig skull from soft tissue. Especially in large-scale meat processing plants' assembly line production, even higher demands are placed on the precision, efficiency, and safety of the deboning process.

[0003] In existing technologies, pig head decapitation primarily relies on manual operation, using traditional boning knives or fixed platforms for segmentation. The common method involves placing the pig head on a platform, with the operator visually and tactilely determining the cutting location and then using a boning knife to slit specific areas. Some devices employ simple limiting frames, insert rods, or pressure clamps to initially secure the pig head, while some systems also utilize pneumatic or hydraulic blades to improve cutting efficiency. However, due to the irregular shape of the pig head, its thick muscle tissue coverage, and large positioning errors, decapitation efficiency, high operational intensity, and excessive residual meat are all problems that arise.

[0004] However, existing technologies have shortcomings in practical applications. During the trimming process, the lack of effective positioning and limiting structures, especially when dealing with critical areas such as the pig's snout and eye sockets, necessitates manual visual estimation for fixation. This is cumbersome, unstable, and prone to causing trimming angle deviations or miscuts, severely impacting work efficiency and processing quality. Therefore, there is an urgent need for an auxiliary device with precise positioning and limiting functions, capable of quickly clamping and positioning the key structures of the pig's head, improving the efficiency and convenience of trimming operations, and thus alleviating the problem of current pig head trimming operations relying on manual judgment and being complex. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A special-shaped knife assembly for positioning and cutting pig heads includes a fixing plate, a connecting plate, a serrated plate, a V-shaped limiting plate, and a splitting blade; The fixing plate is connected to the bracket via the connecting plate; The connecting plate is provided with connection holes for connecting to the bracket; The serrated plate is provided at the lower part of the fixing plate for limiting the pig's lips; The fixed plate is equipped with the V-shaped limiting plate, which is used to embed into the eye socket of the pig skull for positioning. The cleaver is located on one side of the fixed plate and is used to cut the pig's skull and meat tissue.

[0007] As a further description of the above technical solution: The serrated plate is located on one side of the bottom of the fixed plate and has multiple serrated structures arranged in the front-back direction to enhance the limiting stability.

[0008] As a further description of the above technical solution: The V-shaped limiting plate is made of metal sheet with a V-shaped groove in the center and reinforcing ribs on the edge of the groove to improve stability and resistance to deformation during insertion.

[0009] As a further description of the above technical solution: The connecting holes are multiple evenly distributed round holes used to cooperate with the limiting pins or bolts on the bracket to achieve adjustable height and angle of the fixing plate.

[0010] As a further description of the above technical solution: The chopping blade is connected to the fixing plate via a detachable connection structure, which facilitates the replacement and cleaning of the chopping blade.
