[0033] The top surface of operating platform 2 is also provided with two air cylinders 6, and the two air cylinders 6 are located below the side of two lead screws 3 away from motor 32 respectively, and second connecting frame 61 is provided between the two air cylinders 6, and the both ends of second connecting frame 61 are connected to the piston rods 62 of two air cylinders 6 respectively, and second movable slot 42 is further provided on each partition 4, and second connecting frame 61 is provided with the second guide block consistent with the number of partition 4, and second guide block is located in second movable slot 42, and second movable slot 42 is designed to be inclined, and second connecting frame 61 moves along the setting direction of second movable slot 42 with the piston rod 62 of air cylinder 6, and second blade 611 is provided below each first blade 311, and second blade 611 is installed on second connecting frame 61 and moves with second connecting frame 61 to abut or separate from first blade 311.

[0034] The end of second movable slot 42 close to air cylinder 6 is lower than the other end, and the piston rod 62 is movably installed in the sliding groove at the both ends of second connecting frame 61.

[0035] The side of second connecting frame 61 away from air cylinder 6 is provided with multiple wedge-shaped blocks 612, and the two partitions 4 of each group are located between two wedge-shaped blocks 612, and the lower end of partition 4 is provided with movable plate 43, and inclined groove 431 cooperating with wedge-shaped block 612 is arranged on movable plate 43, and the width of inclined groove 431 is greater than the width of wedge-shaped block 612, and wedge-shaped block 612 moves with second connecting frame 61 to abut or separate from inclined groove 431, so that the movable plates 43 on the two partitions 4 of the same group are close to or away from each other.

[0036] The top surface of the operation table 2 is provided with a motor 32, the motor 32 is connected with one of the lead screws 3, one end of each lead screw 3 near the motor 32 is provided with a belt pulley 33, a transmission belt 34 is sleeved between the two belt pulleys 33, when the motor 32 drives one of the lead screws 3 to rotate, the other lead screw 3 rotates synchronously.

[0037] In one specific embodiment, as Figures 1 to 10 shown, the pigskin processing pork skin cutting device provided by the application is mainly used for separating pork and pigskin. It comprises a mounting plate 1 and an operation table 2, the operation table 2 is arranged on the upper surface of the mounting plate 1, two lead screws 3 are horizontally arranged on the top surface of the operation table 2, and the two lead screws 3 are arranged in parallel. One of the lead screws 3 is connected with a motor 32, and the lead screw 3 is driven to rotate by the motor 32. One belt pulley 33 is arranged at one end of each lead screw 3 near the motor 32, and a transmission belt 34 is sleeved between the two belt pulleys 33. The transmission belt 34 and the belt pulley 33 are arranged to enable the two lead screws 3 to rotate synchronously with the motor 32. Six partitions 4 are arranged between the two lead screws 3, the partitions 4 are vertically arranged on the top surface of the operation table 2, and every two partitions 4 form a group, and there are three groups in total. A first connecting frame 31 is arranged on the two lead screws 3, the two ends of the first connecting frame 31 are connected with the two lead screws 3 respectively, a first movable slot 41 is arranged on each partition 4, six first guide blocks are arranged on the first connecting frame 31, and the first guide blocks are respectively embedded in each first movable slot 41. The first movable slot 41 is horizontally and linearly arranged, when the motor 32 drives the lead screw 3 to rotate, the first connecting frame 31 moves linearly along the first movable slot 41. A first blade 311 is arranged between every two partitions 4 in a group, there are three first blades 311 in total, the first blades 311 are arranged on the side of the first connecting frame 31 facing the operation table 2, and the first blades 311 move together with the first connecting frame 31. The pork to be processed is placed on the operation table 2, the side with pigskin is closely attached to the upper surface of the operation table 2, and the pork is located between the two partitions 4 in the same group, the distance between the first blade 311 and the operation table 2 is set as the thickness of the pigskin, when the first blade 311 moves together with the first connecting frame 31, the first blade 311 cuts into the pigskin and the pork, so as to separate the pigskin and the pork.

[0038] Wherein, a gas cylinder 6 is arranged below each of the two lead screws 3, and the gas cylinder 6 is located at the side of the lead screw 3 away from the motor 32. The two ends of the second connecting frame 61 are arranged on the piston rods 62 of the two gas cylinders 6 respectively, and the side of the second connecting frame 61 facing the operation table 2 is provided with a second blade 611, and the gas cylinder 6 drives the second connecting frame 61 and the second blade 611 to move together. It is worth mentioning that a second movable groove 42 is also arranged on each partition plate 4, and six second guide blocks are arranged on the second connecting frame 61, which are respectively embedded in each second movable groove 42, so that the second connecting frame 61 moves along the second movable groove 42. And because the second movable groove 42 is designed to be inclined, the position of the end of the second movable groove 42 close to the gas cylinder 6 is lower than the other end, which makes the second connecting frame 61 and the second blade 611 connected thereto move vertically close to or away from the upper surface of the operation table 2 when the second connecting frame 61 moves horizontally along the second movable groove 42. And in order to prevent the movement of the second connecting frame 61 from being interfered, a sliding groove is arranged at the two ends of the second connecting frame 61, and the piston rod 62 of the gas cylinder 6 is located in the sliding groove. When the second connecting frame 61 moves along the inclined second movable groove 42, the sliding groove also moves with the second connecting frame 61, while the piston rod 62 of the gas cylinder 6 can remain independent and does not interfere with the vertical movement of the second connecting frame 61.

[0039] Wherein, the second blade 611 has three, which are respectively located below each first blade 311, and the second blade 611 moves with the second connecting frame 61 to abut or separate from the first blade 311. In actual use, the initial position of the second blade 611 is close to the bottom of the first blade 311, and the second blade 611 and the first blade 311 cut into the position between the pigskin and the pork together, and then under the guidance of the inclined second movable groove 42, the second blade 611 separates from the first blade 311 and moves towards the operation table 2, thereby generating a downward pressure on the pigskin. And because the length of the second movable groove 42 is shorter than that of the first movable groove 41, when the second blade 611 moves to the end of the second movable groove 42 and stops, the first blade 311 still continues to move along the first movable groove 41. This design makes the second blade 611 be able to effectively press the pigskin while the first blade 311 is cutting the pork and the pigskin, so as to prevent the pigskin from being rolled up under stress when cutting and affecting the cutting, and make the first blade 311 more smoothly cut the pigskin and the pork.

[0040] Here, four wedge-shaped blocks 612 are arranged on the side of the second connecting frame 61 opposite to the air cylinder 6, so that two slabs 4 in each group are located between two wedge-shaped blocks 612. The lower end of each slab 4 is provided with a movable plate 43, and the movable plate 43 is provided with an inclined groove 431 matched with the wedge-shaped block 612. It is worth noting that the width of the inclined groove 431 is designed to be greater than the width of the wedge-shaped block 612, which ensures that when the wedge-shaped block 612 moves with the second connecting frame 61, the vertical movement of the wedge-shaped block 612 will not be interfered by the inclined groove 431 due to the inclined design of the second movable groove 42. On the other hand, when the wedge-shaped block 612 moves with the second connecting frame 61 along the second movable groove 42, the wedge-shaped block 612 will abut or separate from the inclined groove 431, which will cause the movable plates 43 on the two slabs 4 in the same group to move closer to or away from each other. Since the pork to be processed is placed on the operation table 2 and located between the two slabs 4 in the same group, the pork can be clamped and fixed when the movable plates 43 on the two slabs 4 in the same group move closer to each other, which facilitates the operation of cutting the pork and the pork skin.

[0041] In the upper surface of the operation table 2, three groups of air supply grooves 21 are arranged between the two slabs 4 in each group, and the pork to be processed is placed directly above the air supply grooves 21. An air guide 5 is arranged inside the operation table 2, and an air extraction column 51 is arranged above the air guide 5. The air supply grooves 21 and the air guide 5 are connected through the air extraction column 51, and an air inlet 52 is arranged on the side of the air guide 5. In actual operation, the air pump is connected to the air inlet 52 and started to perform air extraction. This operation enables the air extraction column 51 to generate a suction effect on the air supply grooves 21, and then the pork placed above the air supply grooves 21 is subjected to an adsorption effect, so that the pork skin side of the pork can be stretched out and closely attached to the surface of the operation table 2, and the fixed effect of the movable plate 43 ensures that the pork will not roll up into an arc shape when being cut on the operation table 2, thereby enabling the cutting operation to be smoothly performed, accelerating the cutting speed of the pork and the pork skin, and improving the production efficiency of the pork skin.

[0042] In this specific embodiment, six slabs 4 are arranged between the two lead screws 3, which are vertically arranged on the top surface of the operation table 2, and each two slabs 4 form a group, and there are three groups in total. This enables the present application to cut three pieces of pork to be processed at the same time. In other embodiments, the number of slabs 4 can be arranged according to actual needs, and correspondingly, the number of first blades 311 and second blades 611 also depends on the number of slabs 4, that is, the number of groups of slabs 4 determines the number of pieces of pork to be processed that can be cut at the same time.

[0043] The bottom of the operation table 2 is provided with a rotating shaft 22, and the operation table 2 is movably connected with the mounting plate 1 through the rotating shaft 22. The end of the bottom of the operation table 2 away from the rotating shaft 22 is in abutment with or separated from the mounting plate 1 when the rotating shaft 22 rotates.

[0044] The side of the mounting plate 1 away from the rotating shaft 22 is provided with telescopic rods 11. The two ends of each telescopic rod 11 are provided with first rotating rods 111 and second rotating rods 112, respectively. One end of each telescopic rod 11 is movably connected with the mounting plate 1 through the first rotating rod 111, and the other end of each telescopic rod 11 is movably connected with the top of the operation table 2 through the second rotating rod 112.

[0045] The end of the mounting plate 1 close to the rotating shaft 22 is provided with a discharge port 12, and the two ends of the discharge port 12 are provided with baffles 121.

[0046] The mounting plate 1 is further provided below with a support frame 7, and the side of the support frame 7 is provided with a sliding plate 71 connected with the discharge port 12.

[0047] The bottom of the support frame 7 is provided with supporting legs 72, and the bottom of each supporting leg 72 is provided with a rubber pad.

[0048] In a specific embodiment, as shown in Figure 2 、 Figure 8 and Figure 9 , one end of the bottom of the operation table 2 is provided with a rotating shaft 22, and the operation table 2 is movably connected with the mounting plate 1 through the rotating shaft 22. The end of the bottom of the operation table 2 away from the rotating shaft 22 can be in abutment with or separated from the mounting plate 1 when the rotating shaft 22 rotates. Two telescopic rods 11 are arranged on the side of the mounting plate 1 away from the rotating shaft 22. The two ends of each telescopic rod 11 are movably connected with the mounting plate 1 and the top of the operation table 2 through first rotating rods 111 and second rotating rods 112, respectively. Specifically, one end of each telescopic rod 11 is movably connected with the mounting plate 1 through the first rotating rod 111, and the other end of each telescopic rod 11 is movably connected with the top of the operation table 2 through the second rotating rod 112. This design enables the operation table 2 to move under the action of the rotating shaft 22, and the arrangement of the telescopic rods 11 not only ensures the smoothness and stability of the movement process, but also prevents the operation table 2 from being excessively flipped.

[0049] Here, the installation plate 1 is provided with a discharge port 12 at one end close to the rotating shaft 22, and the two ends of the discharge port 12 are provided with baffle plates 121. In addition, a support frame 7 is further provided below the installation plate 1, and the side of the support frame 7 is provided with a sliding plate 71 connected with the discharge port 12. When the operating table 2 is tilted towards the position of the discharge port 12, the divided pigskin and pork can be smoothly poured into the discharge port 12, and the baffle plates 121 can prevent the pigskin and pork from spilling out of the discharge port 12 during pouring. After the pigskin and pork enter the discharge port 12, they slide along the sliding plate 71 into the support frame 7, and a containing container can be placed in the support frame 7 in advance to receive and collect the pigskin and pork sliding from the discharge port 12. In addition, the bottom of the support frame 7 is provided with supporting legs 72, and the bottom of the supporting legs 72 is further provided with rubber pads.
