[0025] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme of the present application will be described clearly and completely below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] Although the present application specification can include various different forms of embodiments, and for some preferred embodiments described in detail in the specification and shown in the drawings, it should be understood that the disclosure of the present application should be regarded as a schematic description of the principles of the present application, and the shown embodiments are not intended to limit the scope of protection of the present application.

[0027] The technical scheme provided by each embodiment of the present application will be described in detail below in combination with the drawings.

[0028] According to an embodiment of the present application, a pig head splitting device is provided. Referring to Figure 1The pig head splitting device comprises a conveying mechanism 1, a positioning and clamping mechanism 2, a first support frame 3 and a splitting part 4. It is to be noted that in the present application, the conveying direction A of the conveying mechanism is defined as the front of the pig head splitting device, the direction opposite to the conveying direction of the conveying mechanism is defined as the back of the pig head splitting device, the direction on the left side of the operator is defined as the left side of the pig head splitting device when the operator faces the front of the pig head splitting device, and the direction on the right side of the operator is defined as the right side of the pig head splitting device.

[0029] Referring to Figure 2 The conveying mechanism 1 can comprise two conveying chains 11 and corresponding power equipment. The conveying chains 11 can rotate in a loop to convey the pig head to the workbench.

[0030] Referring to Figures 2 to 4 The positioning and clamping mechanism 2 is mainly used for carrying and fixing the pig head. The positioning and clamping mechanism 2 is fixedly connected with the conveying chain 11 and moves forward under the driving of the chain to provide the pig head to the workbench. In actual application, a plurality of positioning and clamping mechanisms 2 are fixed on the conveying chain 11. The adjacent positioning and clamping mechanisms 2 are spaced apart by a predetermined distance. Each positioning and clamping mechanism 2 can carry one pig head to be split. These positioning and clamping mechanisms 2 operate in a loop on the conveying chain to complete the automatic splitting operation without manual intervention. Figure 2 Two positioning and clamping mechanisms 2 are exemplarily shown in the figure, but the present application is not limited thereto. Since the positioning and clamping mechanisms 2 operate in a loop under the driving of the conveying mechanism 1, in the description herein, the position of the above-mentioned positioning and clamping mechanism 2 refers to the splitting position on the workbench (for example, the position of the positioning and clamping mechanism 2 shown in the figure) unless otherwise stated. Figure 1

[0031] Referring to Figure 4 The positioning and clamping mechanism 2 mainly comprises a carrying part 21, a first pressing jaw assembly 22 and a second pressing jaw assembly 23. The carrying part 21 is used for carrying the pig head to be split and conveying the pig head to the splitting position on the workbench, where the splitting part 4 performs the splitting operation. Specifically, the carrying part 21 can comprise a front baffle 211, a rear baffle 212, side plates 213 and a bottom plate 214. Alternatively, the carrying part 21 can be regarded as left and right oppositely arranged left and right carrying parts, which are combined to form the carrying part 21. The bottom plate 214 has an opening penetrating through the length direction of the bottom plate. The two side plates 213 of the carrying part 21 are inclined outward, so that the carrying part 21 has a structure of being wide at the top and narrow at the bottom and having an opening at the top. This shape facilitates the placement of the pig head and enables the pig head to have a relatively stable initial posture. The pig head maintains an initial posture of having the lower jaw upward, the eyes downward and the pig nose backward in the positioning and clamping mechanism 2.

[0032] Referring to Figures 4 to 6 ​, the first pressure jaw assembly 22 and the second pressure jaw assembly 23 are respectively hinged to the bearing part 21 and extend above the side plate 213 of the bearing part 21, wherein the first pressure jaw assembly 22 is located in front of the second pressure jaw assembly 23. Specifically, the first pressure jaw assembly 22 comprises oppositely arranged pressure jaws 221 and 222, which have the same structure. Taking the pressure jaw 221 as an example, the pressure jaw 221 comprises a pressure roller 2211, a transmission roller 2212 and a connecting rod 2213. The connecting rod 2213 is hinged to the bottom plate 214 of the bearing part 21 and extends obliquely upward. Above the connecting rod 2213, a component for mounting the transmission roller 2212 and the pressure roller 2211 is connected, which can be generally a bracket type, wherein the vertical part is used for mounting and fixing the transmission roller 2212, and the horizontal part is used for mounting and fixing the pressure roller 2211, the pressure roller 2211 extends above the side plate and faces the pressure roller on the other side in the middle, and the transmission roller 2212 can drive the pressure roller 2211 to move inward. It should be noted that the pressure roller 2211 is deflected forward by a predetermined angle. Specifically, taking the axial direction of the transmission roller 2212 as the reference, the pressure roller 2211 is deflected forward by 20-25 degrees. Correspondingly, the corresponding position of the side plate 213 of the bearing part 21 has an opening, so that the movement operation of the first pressure jaw assembly 22 and the second pressure jaw assembly 23 inward and close to the side plate 213 is not affected.

[0033] Continuing to refer to Figures 4 to 6 , the second pressure jaw assembly 23 comprises oppositely arranged pressure jaws 223 and 224, which have the same structure. Taking the pressure jaw 223 as an example, the pressure jaw 223 comprises a pressure roller 2231, a transmission roller 2232 and a connecting rod 2233. The connecting rod 2233 is hinged to the bottom plate 214 of the bearing part 21 and extends obliquely upward. Above the connecting rod 2233, a component for mounting the transmission roller 2232 and the pressure roller 2231 is connected, the pressure roller 2231 extends above the side plate and faces the pressure roller on the other side in the middle, and the transmission roller 2232 can drive the pressure roller 2231 to move inward. In the embodiment of the present application, the materials of the pressure roller, the pressure roller and the transmission roller can be selected from natural rubber, silicone and other materials that can contact food and have a certain elasticity.

[0034] in combination with reference to Figure 4, the first pressure jaw assembly 22 and the second pressure jaw assembly 23 are located at the relatively rear position of the carrier 21, for example, the first pressure jaw assembly 22 can be located at or near the middle position of the side plate 213 of the carrier 21. In this case, the first pressure jaw assembly 22, the second pressure jaw assembly 23 and the rear baffle 212 cooperate to position and clamp the pig head. Specifically, the pig nose portion of the pig head abuts against the rear baffle 212, and the first pressure jaw assembly 22 and the second pressure jaw assembly 23 contact and press the face position of the pig head inward. Especially the first pressure jaw assembly 22 with the deflection angle can better fit the shape of the face of the pig head, so as to more firmly grip the face position of the pig head.

[0035] Reference Figure 2 and Figure 3 wherein Figure 3 shows another angle of Figure 2 partially. The positioning and clamping mechanism 2 further comprises a guide assembly 24 for limiting the position of the transmission rollers of the first pressure jaw assembly 22 and the second pressure jaw assembly 23, so as to enable the corresponding transmission rollers to move inwardly and approach each other. Specifically, the guide assembly 24 can comprise two guide rails, and the guide rail on one side will be described in detail below. As shown in Figure 2 , the structure of the guide assembly 24 on one side comprises a guide rail 241, a fixed rod 242 and a plurality of springs 243 connecting the guide rail 241 and the fixed rod 242, wherein the guide rail 241 has two expanded sections expanding outwardly at both ends and a straight middle section. When the carrier 21 carrying the pig head enters the operating table, the transmission roller 2212 of the pressure jaw 221 and the transmission roller 2232 of the pressure jaw 223 respectively contact the guide rail 241 of the guide assembly 24, and with the shape of the guide rail 241, the transmission roller 2212 and the transmission roller 2232 are guided inwardly by the guide rail 241, while the transmission roller 2212 drives the pressure roller 2211 and the transmission roller 2232 drives the pressure roller 2231 to move inwardly, so that the pressure roller and the pressure roller grip the pig head. In fact, the width of the preset guide assembly 24 (i.e. the width of the middle section of the guide rail 241) is adapted to the width of the pig head, and the width of the guide assembly 24 determines the degree of inward extrusion of the first pressure jaw assembly 22 and the second pressure jaw assembly 23. And because of the existence of the spring 243, the distance of the inward movement of the guide rail 241 can be fine-tuned to adapt to the pig heads with different widths.

[0036] Further, reference is made to Figure 1 and Figure 2The positioning and clamping mechanism 2 further comprises a pre-guide assembly 25, which can comprise two guide rails, arranged behind the guide assembly 24. That is, when the positioning and clamping mechanism 2 travels on the conveying mechanism 1, it first passes through the pre-guide assembly 25 and then passes through the guide assembly 24. For example, the guide assembly 24 is arranged on the operation table, and the pre-guide assembly 25 is arranged at a distance behind the operation table. The pre-guide assembly 25 is used to pre-position and guide the first pressure jaw assembly 22 and the second pressure jaw assembly 23, so that the first pressure jaw assembly 22 and the second pressure jaw assembly 23 can smoothly contact the guide assembly 24 and enter between the guide assembly 24. The width of at least part of the pre-guide assembly 25 according to the embodiment of the application is greater than the width of the guide assembly 24, wherein the width of the pre-guide assembly 25 refers to the distance between the two guide rails of the pre-guide assembly 25, and the width of the guide assembly 24 can be the maximum width of the guide assembly 24 (i.e. the width of the expansion section at both ends). For example, the width of the rear end between the two guide rails of the pre-guide assembly 25 is greater than the width of the front end, and the width of the front end of the pre-guide assembly 25 is equal to or approximately equal to the width of the rear end expansion section of the guide assembly 24. The front end of the pre-guide assembly 25 is arranged near (for example, below) the rear end of the guide assembly 24, in which case the transmission rollers of the first pressure jaw assembly 22 and the second pressure jaw assembly 23 move (squeeze) inwardly under the guidance of the pre-guide assembly 25, and then the transmission rollers continue to move (squeeze) inwardly under the guidance of the guide assembly 24.

[0037] In some embodiments of the application, the pre-guide assembly 25 can have a shape with a rear end width greater than a front end width, so that the transmission rollers can be accommodated between the two guide rails of the pre-guide assembly 25 regardless of the degree of opening (outward).

[0038] In combination with reference Figure 1 , Figure 2 and Figure 7The first support frame 3 of the pig head splitting device is fixedly arranged at a corresponding position of the operation table. When the carrier 21 carries the pig head to be split to the splitting position of the operation table, the first support frame 3 is located at the opening of the middle position of the bottom plate 214 of the carrier 21. The first support frame 3 comprises a substantially flat top and a support structure for supporting the top, and the support structure can be fixed on the operation table. At the splitting position of the operation table, the top of the first support frame 3 is substantially flush with the bottom plate 214, and the top can be used to receive the splitting knife 41 falling during splitting. The first support frame 3 has a protruding portion 31 at the front portion, for example, the protruding portion 31 is about 35-45 mm higher than the bottom plate 214. When the carrier 21 is located at the splitting position of the operation table, the protruding portion 31 is located outside the carrier 21, that is, a certain distance in front of the front baffle 211 of the carrier 21. With reference to the accompanying drawings, the positioning and clamping mechanism 2 further comprises a fixed rod 26, which is substantially in the shape of a "V" and is arranged in front of the front baffle 211 of the carrier 21 and above the protruding portion 31. When the carrier 21 carrying the split pig head is transmitted forward to above the protruding portion 31, the protruding portion 31 pushes the pig head apart from the middle at the bottom, and the tip of the fixed rod 26 separates the pig head to the two sides and limits the longitudinal displacement of the pig head. Under the cooperation of the protruding portion 31 and the fixed rod 26, the pig head is completely separated and transmitted to the next process.

[0039] Reference Figure 3 At a position of a predetermined distance behind the first support frame 3, a second support frame 5 is also arranged. The second support frame 5 also has a substantially flat top and a support structure for supporting the top. In short, the positional relationship between the second support frame 5 and the carrier 21 is similar to that between the first support frame 3 and the carrier 21. The difference is that the second support frame 5 does not have a protruding portion, and the top of the second support frame 5 is slightly higher than that of the first support frame 3. In some embodiments of the present application, when the carrier 21 travels through the position of the second support frame 5 on the conveying mechanism 1, the second support frame 5 is located at the opening of the middle position of the bottom plate 214, and the top of the second support frame 5 is about 1 cm higher than the bottom plate 214. In this way, the second support frame 5 can lift the pig head to be split carried by the carrier 21 upward, and as the carrier 21 travels forward, the pig nose portion of the pig head can abut against the rear baffle 212 to pre-position the splitting position, so as to ensure that the pig head is not split.

[0040] Reference Figure 8In the embodiment of the present application, the splitting part 4 is arranged on the operation table, which mainly comprises a gantry-shaped tool rest across the conveying mechanism and a splitting knife 41, and a cylinder for driving the movement of the splitting knife can be arranged inside the tool rest. The splitting knife 41 is arranged along the longitudinal direction of the bearing part 21, and has a notch 42 at the front part of the splitting knife 41, which is used to reserve the intact pig brain during the splitting operation. When the bearing part 21 carries the pig head to be split to the splitting position, the conveying mechanism stops running for several seconds, and the cylinder drives the splitting knife to cut down the pig head.

[0041] According to the above technical scheme of the utility model, by carrying the pig head to be split by the bearing part, the pig head is pressed tightly by four pressing claws so that the pig nose part is tightly attached to the rear baffle, so that the pig head can be stably and accurately positioned at the splitting position of the splitting knife, the device has high automation, and the working efficiency and safety are effectively improved.

[0042] Although the present disclosure has been described in detail with reference to particular embodiments, those skilled in the art will understand that various changes and modifications can be made without departing from the spirit and scope of the embodiments. Therefore, the present application is intended to cover modifications and variations of the present application, any modifications, equivalent replacements, improvements, etc. within the spirit and principles of the present application, and should be included in the scope of claims of the present application and equivalents thereof.
