[0024] refer to Figures 1 to 5A back guide device of a splitting machine according to a preferred embodiment of the utility model will be described in detail below, wherein the back guide device of the splitting machine includes a tool holder 10, a clamping cylinder 20, a clamping arm 30 and a guide wheel group, wherein one end of the tool holder 10 is hinged to the in-and-out device of the splitting machine and is located in front of the splitting knife on the splitting machine to cooperate with the splitting knife for guidance during the splitting operation, wherein the clamping cylinder 20 and the clamping arm 30 are both hingedly arranged at the other end of the tool holder 10, and the The output shaft of the clamping cylinder 20 is hinged to the end of the clamping arm 30 away from the tool holder 10, so as to drive the clamping arm 30 to rotate within a predetermined angle range along a predetermined rotation center, wherein the predetermined rotation center is the hinge center of the clamping arm 30 and the tool holder 10, wherein a first angle boundary of the predetermined angle range is that the clamping arm 30 and the tool holder 10 remain parallel, and a second angle boundary of the predetermined angle range is that the angle between the clamping arm 30 and the tool holder 10 is less than 90°, that is, in the clamping When the clamping arm 30 and the knife holder 10 remain parallel, the clamping arm 30 forms an upper rotation limit boundary, and when the clamping arm 30 rotates obliquely downward to the angle between the clamping arm 30 and the knife holder 10 is less than 90 degrees, another limit boundary of the predetermined angle range is formed. In addition, the guide wheel group includes two guide wheels 41 that are obliquely symmetrically distributed, wherein the guide wheels 41 are rotatably connected to the inner side of the clamping arm 30 through a connecting frame 42 to rotate against the back of the pig carcass for guidance. In this way, when the splitting operation is performed, During operation, the clamping cylinder 20 is inflated so that the output shaft of the clamping cylinder 20 extends outward, and the guide wheel 41 is driven by the clamping arm 30 to gradually approach and abut against the back of the pig carcass, so that a clamping guide limit can be performed during the splitting process of the splitting machine, and then when the splitting knife is splitting, the phenomenon of splitting displacement caused by carcass deviation can be prevented, which can greatly improve the splitting accuracy and efficiency. After the splitting operation is completed, the clamping cylinder 20 is deflated, the output shaft retracts, and the guide wheel 41 can be driven by the clamping arm 30 to move away from the back of the pig carcass.

[0025] In one embodiment, an opening groove 101 is provided at the end of the tool holder 10, and ear seats 11 are symmetrically installed on the inner side walls opposite to the opening groove 101, wherein the clamping cylinder 20 is connected between the two ear seats 11 in a rotatable manner, specifically, a rotating shaft is installed in the ear seat 11, and a bearing matching the rotating shaft is fixedly installed on the outer side of the clamping cylinder 20. In addition, the clamping arm 30 is hinged to the outer side of the tool holder 10 through the clamping opening, and the clamping arm 30 is close to the entry and exit device of the splitting machine relative to the clamping cylinder 20.

[0026] In one embodiment, the output shaft of the clamping cylinder 20 is connected to the clamping seat 31 of the clamping arm 30 through a floating joint 21 at the end to facilitate quick installation and disassembly between the clamping cylinder 20 and the clamping seat 31, wherein the clamping seat 31 is located at the other end of the clamping arm 30 opposite to the clamping opening.

[0027] In one embodiment, the guide wheel group includes a gear wheel group and a circular wheel group, wherein the gear wheel group is close to the tool holder 10 and includes two symmetrically distributed conical gear wheels 43, so that the friction between the gear wheel 43 and the spine of the pig carcass can be increased through the outer teeth of the gear wheel 43, thereby improving the clamping stability and guiding stability of the gear wheel 43 on the spine of the pig carcass, wherein the circular wheel group is far away from the tool holder 10 and includes two symmetrically distributed conical circular wheels 44, which are mainly used for guiding during the chopping process.

[0028] Considering the problem that the sizes of live pigs are uneven, the inclination slope of the back of the pig carcass may be different. In the process of guiding by the guide wheel 41, it is possible that the inner side of the guide wheel 41 cannot be closely attached to the back surface for guiding, so the guiding effect is poor. Therefore, it is further preferred to combine Figure 3 and Figure 4 The axles of the two circular supporting wheels 44 are connected symmetrically and obliquely at the inner ends, and the mutually connected parts constitute a circular shaft structure 45. In addition, the connecting frame 42 is provided with a clamp 46 matched with the circular shaft structure 45, and the opening side of the clamp 46 is vertically connected with a locking screw 47, so that after the circular shaft structure 45 is rotated into place, the circular shaft structure 45 can be locked and fixed by the locking screw 47 and the clamp 46. In this way, according to the size and slope of the spine of different pig carcasses, the two conical circular supporting wheels 44 can be properly rotated after loosening the locking screw 47, so that the opening size of the conical circular supporting wheels 44 is adapted to the spine of the pig carcass, and then the locking screw 47 can be reversely locked after rotating into place, so that the guiding stability of the conical circular supporting wheels 44 can be ensured, and it is suitable for guiding on the spines of pig carcasses of different sizes, and has a wide range of applications.

[0029] For pigs of different sizes and shapes, the back of the pig carcass may be slightly different, which makes the guide wheel 41 not directly close to the back. Figure 2 and Figure 5In one embodiment, the connecting frame 42 is hinged to the clamping arm 30 at a middle position near the gear wheel group and the circular wheel group, and the connecting frame 42 is provided with a first shock-absorbing pad 421 on the inner side near the lower part, and a second shock-absorbing pad 422 on the inner side near the upper part, wherein the first shock-absorbing pad 421 is opposite to the inner side of the clamping seat 31, and the second shock-absorbing pad 422 is opposite to the top of the clamping seat 31, so that before guiding, the gear wheel 43 and the circular wheel 44 can be well fitted on the back of the pig carcass through the collision of the first shock-absorbing pad 421 and the second shock-absorbing pad 422 with the clamping arm 30, and in addition, the first shock-absorbing pad 421 and the second shock-absorbing pad 422 can also alleviate the hard contact relationship between the gear wheel 43 and the circular wheel 44 and the back of the pig carcass, so that the back of the pig carcass is not easily damaged.

[0030] In one embodiment, the connecting frame 42 is hinged to the clamping arm 30 through hinge shafts 423 symmetrically distributed on both sides, and a stop arm 424 is sleeved on the hinge shaft 423, and the second shock-absorbing pad 422 is vertically installed on the end of the stop arm 424, so that the position of the second shock-absorbing pad 422 can be adjusted by adjusting the angle of the stop arm 424 relative to the hinge shaft 423, that is, the flipping range of the guide wheel 41 is adjusted, wherein the sleeve portion of the stop arm 424 can be made of elastic material, and the position of the second shock-absorbing pad 422 can be adjusted by direct rotation, but it is preferably made of rigid material, that is, a structure similar to a clamp is provided, and the opening is locked by a locking screw to fix the stop arm 424 on the hinge shaft 423. In this way, when the stop arm 424 is fixed, the position of the second shock-absorbing pad 424 is not easy to move.

[0031] In one embodiment, a spray pipe 12 is provided in the knife holder 10, and the spray pipe 12 extends along the length direction of the knife holder 10, and a spray hole is provided at the bottom of the spray pipe 12, and the knife holder 10 is provided with an avoidance opening corresponding to the spray hole, so that hot water / cold water can be automatically sprayed during the splitting process to clean and disinfect the splitting half knife below to prevent cross infection of pork.
