[0002] Currently, in the meat slaughtering and processing industry, slaughtering production lines are becoming increasingly large-scale and automated. However, the vast majority of pig heads are still split manually. Manual splitting has disadvantages such as high labor intensity, great safety risks, unstable splitting accuracy that can easily damage the pig's brain, and low efficiency. Therefore, it is of great significance to develop a fully automated pig head splitting device. Utility Model Content

The positioning pusher mechanism drives the pig's head along the guide rail. When the pig's head reaches the primary alignment mechanism, the positioning pusher mechanism stops working. The primary alignment mechanism then presses the pig's head left and right, up and down, keeping the pig's snout facing forward and cheeks facing upward on the guide rail. Next, the positioning pusher mechanism continues working, driving the pig's head to the secondary alignment mechanism. At this point, the positioning pusher mechanism stops working, and the secondary alignment mechanism supports the pig's head from both sides to ensure that the splitting mechanism can split the pig's head between its cheeks. Then, the splitting mechanism splits the pig's head. Finally, the positioning pusher mechanism works again, pushing the pig's head to the designated workstation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 As shown, this utility model discloses an automatic pig head splitting device, comprising:

[0030] The frame 1 is equipped with a guide rail 2 and a positioning push plate mechanism 3. The guide rail 2 consists of two V-shaped structure guide rails, which have a good posture maintenance and guiding effect, and can ensure that the posture of the pig head will not change much when it slides in the guide rail 2. The positioning push plate mechanism 3 is used to push the pig head along the direction of the guide rail 2 in sequence through the first correction mechanism 4, the second correction mechanism 6 and the splitting mechanism 7.

[0031] The primary correction mechanism 4 is used to squeeze the pig's head left and right and up and down, so that the pig's head is kept in the position of the pig's mouth facing forward and cheeks facing upward on the guide rail 2.

[0032] Secondary straightening mechanism 6 is used to support the pig's head from the left and right, so that the splitting mechanism 7 splits the pig's head in the middle of the two cheeks.

[0033] The splitting mechanism 7 is used to split the pig's head. The splitting mechanism 7 includes a drive mechanism, a fixed frame and a splitting blade. One end of the drive mechanism is fixed to the frame 1 through the fixed frame, and the other end is connected to the splitting blade. The drive mechanism moves up and down with the splitting blade to split the pig's head in half.

[0034] Compared with existing technologies, this application has the following advantages: In use, firstly, the pig's head flows into the guide rail 2 via the feeding line 9. The positioning pusher mechanism 3 drives the pig's head to move along the guide rail 2. When the pig's head reaches the primary alignment mechanism 4, the positioning pusher mechanism 3 stops working. The primary alignment mechanism 4 then presses the pig's head left and right and up and down, keeping the pig's head in a forward-facing and cheek-up position on the guide rail 2. Next, the positioning pusher mechanism 3 continues working, driving the pig's head to the secondary alignment mechanism 6. The positioning pusher mechanism 3 then stops working, and the secondary alignment mechanism 6 supports the pig's head from left and right to ensure that the splitting mechanism 7 can split the pig's head between its cheeks. Then, the splitting mechanism 7 splits the pig's head. Finally, the positioning pusher mechanism 3 works again to drive the pig's head to the designated workstation. The above process is repeated, with the positioning pusher mechanism 3 working cyclically to move the pig's head to each workstation to complete various operations. In summary, the automatic pig head splitting device provided by this application completely replaces manual labor, has high splitting accuracy and efficiency, and greatly reduces the labor intensity of personnel.

[0035] Following the above embodiment, more specifically, the positioning push plate mechanism 3 includes a positioning push plate 31 and a drive mechanism for driving the positioning push plate 31 to move back and forth around the guide rail 2. The positioning push plate 31 is used to push the pig's head to move on the guide rail 2. Specifically, as... Figure 2As shown, the positioning push plate mechanism 3 also includes a detection plate 32 and a positioning push rod 33. The detection plate 32 and the positioning push rod 33 are fixed on the positioning push plate 31, and the positioning push plate 31 is fixed on the drive mechanism. When the drive mechanism drives the positioning push plate 31 to move, the positioning push rod 33 drives the pig head to move on the guide rail 2. The positioning detection plate 32 is matched with the detection mechanism (such as a photoelectric sensor) to sense whether the positioning push plate 31 has moved to the designated position and sends the sensing signal to the controller. The controller controls whether the drive mechanism works according to the sensing signal, thereby controlling the start and stop position of the positioning push rod 33, and thus controlling the pig head to stop at the designated position. The drive mechanism may include a motor, a sprocket, and a ring conveyor chain structure. The motor drives the sprocket to rotate, thereby driving the ring conveyor chain to rotate cyclically. Since the positioning push plate 31 is fixed on the ring conveyor chain, the ring conveyor chain drives the positioning push plate 31 to rotate cyclically along the guide rail 2.

[0036] Following the above embodiment, more specifically, the primary correction mechanism 4 includes a meat-cutting mechanism 5 for cutting off adhering meat. The designed meat-cutting mechanism 5 facilitates subsequent processes of breaking the pig's head and removing the pig's brain.

[0037] Specifically, such as Figure 3 As shown, the meat cutting mechanism 5 includes a first spring 51, a slide rail 52, a slide rail slider 53, a fixing plate 54, and a circular blade 55. The circular blade 55 is fixed on the slide rail 52. One end of the slide rail 52 is slidably mounted on the fixing plate 54 via the slide rail slider 53, and the other end of the slide rail 52 is fixed on the fixing plate 54 via the first spring 51. The fixing plate 54 is fixed on the first support frame 43.

[0038] It should be noted that there is some sticky meat between the cheeks on both sides of the pig's head. When breaking the pig's head, this sticky meat will create significant resistance. Therefore, cutting off the sticky meat in advance will facilitate the subsequent processes of breaking the pig's head and removing the brain. During the process of the positioning push plate mechanism 3 pushing the pig's head from the primary alignment mechanism 4 to the secondary alignment mechanism 6, it will pass through the sticky meat cutting mechanism 5. The circular blade 55 of the sticky meat cutting mechanism 5 will act on the sticky meat and cut it off.

[0039] The specific principle is as follows: There is a skull under the sticky meat. In its natural state, the lowest point of the circular knife 55 is lower than the skull. When the pig's head passes by, the circular knife 55 is subjected to force, and the slide rail 52 slides along the slide rail slider 53. In turn, the slide rail 52 will squeeze the first spring 51, and the first spring 51 will generate a reaction force. Under the action of the first spring 51, the circular knife 55 will be pressed tightly against the skull, achieving the "cutting" effect and cutting off the sticky meat.

[0040] Following the above embodiments, more specifically, as Figure 3As shown, the primary straightening mechanism 4 also includes a clamping device 41, a pressing device 42, and a first support frame 43. The first support frame 43 is fixed on the frame 1, and the clamping device 41 and the pressing device 42 are fixed on the first support frame 43. The clamping device 41 and the pressing device 42 are used to squeeze the pig's head left and right and up and down, respectively.

[0041] It should be noted that after the pig's head falls from the feeding line 9 onto the guide rail 2, the pig's head posture cannot be guaranteed to be suitable for splitting. The primary correction mechanism 4 is responsible for correcting the pig's head to the ideal posture (the pig's cheeks are on both sides of the center line of the guide rail 2, the more symmetrical the better). The clamping device 41 pushes the pig's head from both sides simultaneously, so that the pig's head is in a symmetrical posture relative to the center line of the guide rail 2 under the action of external force. However, when the external force is removed, the pig's head may return to its original incorrect posture. Therefore, in the second step, the pressing device 42 presses on the pig's cheeks to make the pig's head rotate vertically to ensure that the pig's head is in the correct posture.

[0042] Specifically, both the clamping device 41 and the pressing device 42 include a cylinder and a pressure plate. One end of the cylinder is fixed to the first support frame 43, and the other end is connected to the pressure plate, so that the cylinder extends and retracts to drive the pressure plate to move. For example, the clamping device 41 includes two cylinders in the horizontal direction, and the extension and retraction of the cylinders drives the two pressure plates in the horizontal direction to move, so as to realize the left and right squeezing of the pig's head; similarly, the pressing device 42 includes one cylinder, and the extension and retraction of the cylinder drives the pressure plate in the vertical direction to squeeze the pig's head on the guide rail 2, that is, to realize the up and down squeezing of the pig's head.

[0043] Following the above embodiments, more specifically, as Figure 4 , Figure 5 As shown, the secondary alignment mechanism 6 includes a second support frame 61, an alignment rod 62, a guide rod 63, and a second spring 64. The second support frame 61 is fixed to the frame 1. One end of the alignment rod 62 is hinged to the second support frame 61, and the other end of the alignment rod 62 is connected to one end of the guide rod 63. The second spring 64 is fitted onto the guide rod 63, and the other end of the guide rod 63 is movably inserted through the second support frame 61. When the pig's head touches the alignment rod 62, the alignment rod 62 drives the guide rod 63 to move, which in turn moves the second spring 64 fitted onto it. When the guide rod 63 moves outward from the second support frame 61, it compresses the second spring 64 into the second support frame 61. The second spring 64 then reacts against the guide rod 63, and this force enables the alignment rod 62 to support the pig's head from both sides, allowing the splitting mechanism 7 to split the pig's head between its cheeks.

[0044] Following the above embodiment, more preferably, the secondary straightening mechanism 6 further includes a deflector plate 65, which is fixed on the second support frame 61 and is used to prevent the splitting mechanism 7 from lifting the pig's head. In some cases, the pig's head is not completely split in half, and the pig's head will get stuck in the splitting blade and rise with it. Therefore, the deflector plate 65 is set to act on the cheeks on both sides, so that when the splitting blade lifts the pig's head, it can "push" the pig's head off.

[0045] Following the above embodiment, more specifically, it also includes a feeding mechanism 8, which is used to push the pig head to a designated workstation. Due to the design of the feeding mechanism 8, compared to pushing the pig head via the positioning pusher mechanism 3, which requires cyclical rotation, there must be a gap between the positioning pusher mechanism 3 and the next process step. Consequently, when the pig head falls from the positioning pusher mechanism 3 into the next process step, the pig head does not slide in a flat plane, which may cause the pig head's posture to change when it reaches the next process step, thus hindering the operation of the next process. Furthermore, the feeding mechanism 8 can also change the direction of the pig head's movement, so that the next process step does not need to be designed in a linear sequence with this equipment; the next process step can be designed parallel to this process step to better utilize space.

[0046] Following the above embodiment, more specifically, the feeding mechanism 8 includes a splitting mechanism for pressing against the cheeks on both sides of the pig's head to split the pig's head open. With this splitting mechanism designed, the halved pig's head can be automatically split open before entering the next process, thus eliminating the need for splitting in the next process and facilitating its operation.

[0047] Following the above embodiments, more specifically, as Figure 6 As shown, the feeding mechanism 8 also includes a third support frame 81, a feeding cylinder 82, and a feeding push plate 83. The third support frame 81 is fixed on the machine frame 1. One end of the feeding cylinder 82 is fixed on the third support frame 81, and the other end of the feeding cylinder 82 is connected to the feeding push plate 83. The extension and retraction of the feeding cylinder 82 will drive the feeding push plate 83 to push the pig head to the next process. At the same time, the splitting mechanism includes a splitting cylinder 84 and a splitting pressure plate 85. One end of the splitting cylinder 84 is fixed on the third support frame 81, and the other end of the splitting cylinder 84 is connected to the splitting pressure plate 85. The extension and retraction of the splitting cylinder 84 will drive the splitting pressure plate 85 to press the pig head, thereby splitting the split pig head in half.

[0048] In summary, this application enables automatic feeding, automatic positioning, and automatic splitting without manual intervention, resulting in high efficiency. It also considers the downstream process of removing pig brains, automatically splitting the pig's head, significantly reducing labor intensity, improving the working environment, and increasing work efficiency.

[0049] The process flow of this application is as follows: the feeding line 9 conveys the pig head, the pig head falls onto the guide rail 2, the pig head is aligned once, the sticky meat is cut off, the pig head is aligned a second time, the pig head is split in half, the pig head is broken open, and the pig head is unloaded, as detailed below:

[0050] 1. The feeding line 9 carries the pig head to this equipment. Preferably, the pig head has a specific posture requirement on the feeding line 9 to ensure that when the pig head falls from the feeding line 9 onto the guide rail 2, it meets the posture requirement of the pig's snout pointing forward and the cheeks facing upward.

[0051] 2. The circular conveyor chain operates, driving the positioning push plate 31 to push the pig head to the primary alignment mechanism 4. The positioning push rod 33 is fixed on the tibia section of the pig head (the positional relationship between the tibia section and the pig brain is relatively accurate and can be used to position the pig head).

[0052] 3. The primary alignment mechanism 4 is responsible for correcting the pig's head to the ideal posture. The clamping device 41 pushes the pig's head from both sides simultaneously, so that the pig's head is in a symmetrical posture relative to the center line of the guide rail 2 under the action of external force. The pressing device 42 presses on the cheeks of the pig's head, so that the pig's head rotates in the vertical direction, ensuring that the pig's head is in the correct posture.

[0053] 4. During the process of the pig's head moving from the primary straightening mechanism 4 to the secondary straightening mechanism 6, it will pass through the sticky meat cutting mechanism 5. The circular blade 55 of the sticky meat cutting mechanism 5 will act on the sticky meat and cut it off.

[0054] 5. When the positioning push plate 31 pushes the pig's head to the secondary alignment mechanism 6, the detection sensor detects the detection plate 32, and the positioning push plate 31 stops. At this time, the alignment rod 62 will contact the pig's head, and the second spring 64 will be compressed by force, which in turn enables the alignment rod 62 to apply a force to the pig's head. This force can "hold" the pig's head and ensure that the chopping knife hits the middle of the cheeks.

[0055] 6. The chopping knife system performs a chopping action, splitting the pig's head open;

[0056] 7. Positioning push plate 31 pushes the pig head to the feeding mechanism 8, the prying cylinder 84 is activated, the prying pressure plate 85 presses on the cheeks on both sides of the pig head to pry the pig head open; then, the feeding cylinder 82 is activated, driving the feeding push plate 83 to push the pig head to the next process (manual pig brain removal station).
