Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of splitting machines, in particular to a splitting knife used for a pig carcass splitting machine. Background Art
[0002] In the current meat processing industry, the splitting of pig carcasses is a crucial part of the slaughtering process, which directly affects the quality and efficiency of subsequent meat cutting and processing. Traditional pig carcass splitting machines generally adopt a fixed splitting knife design. This type of equipment usually uses strong mechanical force to cut the suspended pig carcasses longitudinally, aiming to achieve fast and accurate splitting operations. However, the existing technical solutions still have some shortcomings in practical applications.
[0003] First, because traditional splitting knives act directly on the pig carcass, they often lack effective guidance and buffering mechanisms. During high-speed cutting, the pig carcass is prone to unexpected rotation or translation under the blade due to its own weight and tissue elasticity, causing the splitting line to deviate from the center, that is, the knife deviation phenomenon occurs. This knife deviation not only affects the flatness and aesthetics of the cut surface, but may also cause damage to part of the meat, increase the difficulty of meat grading, and affect the market value of the final product. Secondly, in order to solve the problem of instability of the pig carcass during the cutting process, some splitting machine designs attempt to improve cutting accuracy by strengthening the fixing measures for the pig carcass. However, although this approach can reduce the knife deviation to a certain extent, it significantly increases the preparation time before the operation and the complexity of the equipment, and reduces the overall processing efficiency. At present, no effective solution has been proposed for the problems in the relevant technology. Utility Model Content

[0007] Furthermore, in order to realize the cleaning function of the chopping knife surface, a placement plate is fixedly connected to one side of the surface of the lifting plate, a clamping plate is fixedly installed above the placement plate, a lifting threaded rod is threadedly connected to the clamping plate, and an extrusion plate is rotatably connected to the bottom of the lifting threaded rod, and a cleaning sponge is fixedly installed between the extrusion plate and the placement plate.
[0008] Furthermore, in order to reduce the friction force when the lifting plate slides in the contraction groove, lifting grooves are opened on both sides of the surface of the lifting plate, and rolling pulleys are rotatably installed at both ends of the contraction groove, and the rolling pulleys are rollingly installed in the lifting groove.
[0009] Furthermore, in order to facilitate the twisting of the lifting threaded rod, a twisting column is fixedly connected to the top end of the lifting threaded rod, and the surface of the twisting column is provided with anti-slip grooves.
[0010] Furthermore, in order to prevent noise from being generated when the top of the shrinkage plate contacts the bottom surface of the bearing plate, a shock-absorbing rubber pad is fixedly installed on the top of the shrinkage plate.

[0012] Furthermore, in order to realize the replacement of the splitting knife on the support plate, loading and unloading plates are fixedly connected to both sides of the top of the splitting knife, and the loading and unloading plates are fixedly installed on the support plate by bolts.
[0013] The beneficial effects of the utility model are as follows: before the pig carcass is cut by the splitting knife, the splitting knife of the present application is driven to move by a splitting machine, and after the splitting knife is gradually driven to approach the surface of the pig carcass, the positioning plate at the bottom end of the lifting plate is first contacted and pressed on the pig carcass to be cut, so as to achieve extrusion and limitation of the pig carcass; after the splitting knife is continuously pressed by the splitting machine, the lifting plate and the positioning plate are relatively moved with the splitting knife, so that the splitting knife moves downward, and the pig carcass squeezed and fixed under the positioning plate is split in half; the squeezing of the positioning plate can effectively prevent the pig carcass from being offset during cutting, thereby causing the knife to deviate, thereby achieving more accurate splitting of the pig carcass, and there is no need to fix the pig carcass to be cut on the splitting machine alone, thereby greatly improving the efficiency of the pig carcass splitting processing.
