Description

Technical Field

[0001] The present invention belongs to the technical field of pork jerky packaging, and particularly relates to a quantitative feeding device for single-piece packaging of pork jerky. Background Art

[0002] Pork jerky is a sliced meat product made from pork or beef through pickling and baking. The earliest pork jerky in China referred to a kind of leisure pork product with a red color made in southern Fujian and Chaoshan regions. Pork jerky is a sliced meat product made from pork through pickling and baking. Its color is brownish red, its texture is tight and it is convenient for storage and transportation. Since the pork jerky is pickled, the surface of the finished pork jerky has sauce. In order to facilitate the transportation of the pork jerky, a protective package needs to be covered on the surface of the pork jerky to prevent external environmental pollution of the pork jerky. However, the traditional packaging of pork jerky basically relies on manual filling by workers. This not only results in low efficiency due to the working hours of the workers, but also it is not easy to ensure that the number of pork jerky in each package is the same due to manual filling. When the existing robotic arm is used to fill the pork jerky, when grasping the pork jerky each time, the sauce on the surface of the pork jerky will stick to the surface of the robotic claw, and when putting down the pork jerky, the pork jerky will deviate from the expected position due to the stickiness of the sauce. Over time, due to the thickening of the sauce, it is not easy to grasp the pork jerky, and it may also damage the pork jerky due to the same spacing as when starting to grasp the pork jerky. To solve the above problems, a quantitative feeding device for single-piece packaging of pork jerky is proposed in this application. Summary of the Invention

[0017] Embodiment 1 As Figures 1 to 12 shown; Combined with the above content: In order to achieve high-efficiency quantitative feeding of pork jerky, this quantitative feeding device for single-piece packaging of pork jerky, a quantitative feeding device for single-piece packaging of pork jerky, includes a feeding component 1, a pork jerky conveyor line 3 arranged on one side of the feeding component 1, and a pork jerky packaging line 4 arranged on the side of the feeding component 1 away from the pork jerky conveyor line 3.

A negative pressure box 21 is arranged on the bottom surface of the positioning block 13. The positioning block 13 is rotationally connected to the negative pressure box 21 through a bearing. An exhaust fan 22 is installed on the surface of the negative pressure box 21. The air suction end of the exhaust fan 22 is inserted into the interior of the negative pressure box 21. A limiting shell 11 is fixedly connected to the upper surface of the positioning block 13. A linkage shaft 116 is fixedly connected to the upper surface of the limiting shell 11. A driven disk B111 is sleeved on the surface of the linkage shaft 116. A support frame 14 is arranged above the positioning block 13. A motor 15 is installed on the surface of the support frame 14. The output shaft of the motor 15 penetrates through the surface of the support frame 14 and is fixedly connected to a limiting disk 16. A limiting post B115 is fixedly connected to the bottom surface of the limiting disk 16. A plurality of positioning grooves A are evenly formed on the surface of the driven disk B111. The limiting post B115 is inserted into the interior of the positioning groove A. A positioning disk B114 is fixedly connected to the bottom surface of the limiting disk 16. Two limiting posts A18 are fixedly connected to the upper surface of the limiting disk 16. A positioning cylinder 117 is fixedly connected to the surface of the linkage shaft 116. A driven disk A19 is fixedly connected to the upper end of the positioning cylinder 117. A plurality of positioning grooves B are evenly formed on the surface of the driven disk A19. The limiting post A18 is inserted into the interior of the positioning groove B. A positioning disk A17 is fixedly connected to the surface of the limiting disk 16. A limiting tooth ring 123 is arranged inside the limiting shell 11. The linkage shaft 116 penetrates through the limiting shell 11 and is fixedly connected to the limiting tooth ring 123. A plurality of linkage holes 125 are evenly formed inside the positioning block 13. A support arm 12 is arranged inside each linkage hole 125. The support arm 12 is slidably connected to the positioning block 13 through the linkage hole 125. A spring B126 is arranged inside the linkage hole 125. Two ends of the spring B126 are respectively fixedly connected to the positioning block 13 and the support arm 12. One end of each support arm 12 away from the positioning block 13 is fixedly connected to a suction cup body 121. A linkage rod 124 is fixedly connected to one side of each support arm 12 close to the limiting shell 11. Limiting grooves 113 are formed at the positions of the limiting shell 11 corresponding to the linkage rods 124. The linkage rod 124 penetrates through the limiting shell 11 through the limiting groove 113 and is slidably connected to the limiting shell 11. The linkage rod 124 is in mutual fit with the limiting tooth ring 123. A plurality of curved grooves A are evenly formed on the surface of the driven disk B111. The positioning disk B114 is in mutual fit with the driven disk B111 through the curved groove A. A plurality of curved grooves B are evenly formed on the surface of the driven disk A19. The positioning disk A17 is in mutual fit with the driven disk A19 through the curved groove B. And the two limiting posts A18 are located on one side of the limiting post B115.

[0018] In this embodiment: when using the device, first connect the meat jerky conveyor line 3 and the meat jerky packaging line 4 to an external power supply and then start them, and at the same time connect the exhaust fan 22 to an external power supply and then start them, the exhaust fan 22 will draw air out from the inside of the negative pressure box 21, and the meat jerky that has been cut through the previous process will be placed on the surface of the meat jerky conveyor line 3 and conveyed to the bottom of the suction cup body 121, and then connect the motor 15 to an external power supply and then start it, the output shaft of the motor 15 will drive the limit plate 16 to rotate, and the rotation of the limit plate 16 will drive the limit column B115 to rotate with the center of the limit plate 16 as the axis, and when the limit column B115 rotates to a certain position, it will be inserted into the inside of the positioning groove A, and then it will pass through The limiting column B115 drives the driven disk B111 to rotate with the linkage shaft 116 as the axis. When the driven disk B111 rotates, the limiting shell 11 drives the positioning block 13 to rotate inside the negative pressure box 21. When the limiting column B115 drives the driven disk B111 to rotate to ninety degrees, it will detach from the inside of the positioning groove A. At this time, the curved groove A will fit with the positioning disk B114, and the driven disk B111 will be limited by the positioning disk B114. At this time, the support arm 12 is in a stopped state, and the limiting disk 16 continues to rotate. The limiting column A18 will be inserted into the inside of the positioning groove B, thereby driving the driven disk A19 to rotate, and when the driven disk A19 rotates, it will drive the limiting gear ring 123 to rotate. When the linkage rod 124 does not move but the limiting tooth ring 123 rotates, the limiting tooth ring 123 will squeeze the linkage rod 124 due to its shape, indirectly causing the support arm 12 to move toward the inside of the linkage hole 125, and the spring B126 will be compressed, while the linkage rod 124 will go straight up and down due to the limitation of the limiting groove 113, until the suction cup body 121 rotates to a certain angle, the limiting column A18 will detach from the inside of the positioning groove B, and the positioning plate A17 will limit the driven plate A19 through the curved groove B. At this time, the linkage rod 124 will be at the lowest point of the limiting tooth ring 123, and just after the suction cup body 121 contacts with the pork jerky, due to the negative pressure box 21, the suction cup body 121 will suck the meat jerky, so that the suction cup body 121 is close to the meat jerky when sucking it, to prevent the meat jerky from shifting during suction. The limit plate 16 continues to rotate, and the second limit column A18 will be inserted into another positioning groove B again to drive the driven plate A19 to rotate. The driven plate A19 will again drive the limit tooth ring 123 to rotate. Through the elastic potential energy of the spring B126, the linkage rod 124 slides upward on the surface of the limit tooth ring 123, and the support arm 12 will move the meat jerky upward. This cycle is repeated to achieve the absorption of the meat jerky, avoiding the low efficiency and non-quantification disadvantages of traditional manual labor, and also avoiding the possibility of traditional mechanical claws damaging the meat jerky.

[0019] Going further: In an alternative embodiment, the driven disk B111 is rotatably connected to the linkage shaft 116. A ratchet wheel 118 is fixedly connected to the surface of the linkage shaft 116 inside the driven disk B111. A ratchet tooth 120 is rotatably connected to the inside of the driven disk B111 through a rotating shaft. The ratchet tooth 120 is meshed with the ratchet wheel 118. A torsion spring is wound around the surface of the rotating shaft, so that the limit shell 11 and the limit tooth ring 123 can rotate respectively.

[0020] In this embodiment: when the driven disk B111 rotates, the linkage shaft 116 is driven to rotate by the suction cup body 121 meshing with the air passing hole 119, so that the suction cup body 121 and the limit shell 11 rotate synchronously, which can avoid the situation that when the linkage rod 124 rotates, the limit tooth ring 123 does not rotate. The shape of the limit tooth ring 123 limits the linkage rod 124, causing the linkage rod 124 to move up and down when rotating, thus creating unnecessary jitter and increasing the risk of the jerky falling during transportation. When the positioning cylinder 117 rotates, it will drive the limit tooth ring 123 to rotate through the linkage shaft 116, and due to the ratchet wheel 118, the driven disk B111 will not rotate, which will not affect the movement of the support arm 12.

[0021] Furthermore: In an alternative embodiment, a receiving groove 127 is formed inside the positioning block 13. The receiving groove 127 communicates with the linkage hole 125. A connecting cylinder 128 is arranged inside the receiving groove 127. The connecting cylinder 128 is slidably connected to the positioning block 13 through the receiving groove 127. A corrugated pipe 112 is fixedly connected to the surface of the connecting cylinder 128. An air passing hole 119 is formed inside the positioning block 13. One end of the corrugated pipe 112 away from the connecting cylinder 128 is inserted into the air passing hole 119. A limit ring A130 is arranged inside the receiving groove 127. The limit ring A130 is rotatably connected to the positioning block 13. The limit ring A130 is fixedly connected to the negative pressure box 21 through a connecting rod. Two corrugated plates 129 are symmetrically and fixedly connected to the surface of the connecting cylinder 128. One end of the corrugated plate 129 away from the connecting cylinder 128 is fixedly connected to the positioning block 13. A conical piece is fixedly connected to the upper surface of the limit ring A130, and the conical piece is located below the connecting cylinder 128 on the side facing the jerky packaging line 4, so that the connecting cylinder 128 at this position can move up and down. The corrugated plate 129 is located at the communication position between the receiving groove 127 and the linkage hole 125, so that the connecting cylinder 128 can maintain sealing while moving.

[0022] In this embodiment: when one of the support arms 12 rotates towards the direction of the meat jerky packaging line 4, the connecting cylinder 128 will slide on the surface of the conical piece. Due to the shape of the conical piece, the connecting cylinder 128 will also rise inside the receiving groove 127 during rotation until the suction cup main body 121 stops directly above the meat jerky packaging line 4. At this time, the connecting cylinder 128 is located at the highest point of the conical piece. When the connecting cylinder 128 moves, the corrugated plates 129 on both sides will contract and expand to different degrees as the connecting cylinder 128 moves. Sealing slide rails are provided on both sides of the corrugated plate 129 for the contraction and expansion of the corrugated plate 129, realizing the sealing of the linkage hole 125 while not affecting the movement of the connecting cylinder 128. As the limiting gear ring 123 rotates, the support arm 12 will move downward inside the linkage hole 125. Finally, the support arm 12 will block the connection end with the connecting cylinder 128, making it impossible for the connecting cylinder 128 to suck air from the inside of the support arm 12 through the linkage hole 125, so that the meat jerky detaches from the surface of the suction cup main body 121. Since the support arm 12 moves downward when the connecting cylinder 128 is closed, the detachment height of the meat jerky is relatively low, preventing the meat jerky from deviating in position due to wind resistance during falling caused by the height problem, resulting in difficulties in packaging. Due to the fact that taking and placing the meat jerky are simultaneous, the limit ring A 130 is only provided on one side close to the meat jerky packaging line 4, which is convenient for closing the air and placing the meat jerky, and will not affect taking and conveying the meat jerky at all.

[0023] Furthermore: In an alternative embodiment, a limiting plug 110 is slidably connected inside the connecting cylinder 128. A spring A 122 is arranged inside the connecting cylinder 128. The two ends of the spring A 122 are fixedly connected to the limiting plug 110 and the connecting cylinder 128 respectively. The end of the limiting plug 110 away from the connecting cylinder 128 is inserted into the linkage hole 125 and fits with the support arm 12.

[0024] In this embodiment: when the support arm 12 blocks the connection end of the connecting cylinder 128, it will squeeze the limiting plug 110. The limiting plug 110 will move towards the inside of the connecting cylinder 128, and the spring A 122 will be compressed until the limiting plug 110 seals the inside of the connecting cylinder 128, preventing the support arm 12 from being unable to seal the connecting cylinder 128, and the remaining gas will affect the accuracy when placing the meat jerky.

[0025] Furthermore: In an alternative embodiment, the exhaust end of the exhaust fan 22 is fixedly connected to a high-pressure box 23. The surface of the high-pressure box 23 is fixedly connected to an air pipe 26. A ring groove 27 is formed on the surface of the positioning block 13 inserted inside the negative-pressure box 21. One end of the air pipe 26 away from the high-pressure box 23 penetrates through the negative-pressure box 21 and is inserted into the ring groove 27. A moving pipe 211 is arranged inside the air passing hole 119. The moving pipe 211 is slidably connected to the positioning block 13 through the air passing hole 119. A spring C29 is arranged inside the air passing hole 119. Two ends of the spring C29 are respectively fixedly connected to the moving pipe 211 and the positioning block 13. A limiting ring B210 is fixedly connected inside the negative-pressure box 21. The moving pipe 211 is in mutual contact with the limiting ring B210. An air inlet hole 28 is formed on one side of each moving pipe 211 facing the ring groove 27. A collection box 212 is arranged on one side of the positioning block 13 where the air pipe 26 is located. The collection box 212 is located below the suction cup main body 121. A convex block is fixedly connected to the upper surface of the limiting ring B210, and the convex block is located on the side close to the air pipe 26. When the moving pipe 211 is located on the surface of the convex block, the moving pipe 211 moves upward, and the air inlet hole 28 is no longer affected by the negative pressure inside the negative-pressure box 21. The air inlet hole 28 is aligned with the ring groove 27, so that the air pipe 26 communicates with the air inlet hole 28.

[0026] In this embodiment: When the suction cup main body 121 rotates again after putting down the dried meat slices, the moving pipe 211 will slide on the surface of the limiting ring B210 until it comes into contact with the convex block. The moving pipe 211 will be squeezed and move upward inside the air passing hole 119, and the spring C29 will be compressed. Until the moving pipe 211 rotates 90 degrees, the moving pipe 211 will be at the highest point of the convex block. The air inlet hole 28 will enter the air passing hole 119 and be parallel to the ring groove 27. The gas inside the high-pressure box 23 will finally pass through the air pipe 26 and then through the moving pipe 211 and be discharged from the inside of the suction cup main body 121. This gas will clean the pipeline inside the suction cup main body 121 to prevent the sauce from blocking the pipeline, and the removed sauce will finally fall into the collection box 212, realizing the collection. Therefore, the convex block is only arranged on the side close to the collection box 212, so it will not affect other suction cup main bodies 121.

[0027] Furthermore: In an alternative embodiment, a release hole is formed on the surface of the high-pressure box 23. A filter screen 25 is installed inside the release hole. One side of the high-pressure box 23 where the release hole is located is rotatably connected to a baffle 24 through a bearing seat. The baffle 24 is inserted into the release hole.

[0028] In this embodiment: Since there is a spacing for each cleaning, in order to prevent the pressure inside the high-pressure box 23 from being too high, a baffle 24 is provided. When the pressure inside the high-pressure box 23 is too high, the baffle 24 will be pushed by the gas to rotate on the surface of the bearing seat, thereby releasing the pressure inside the high-pressure box 23 and preventing risks such as explosion. Because one side of the baffle 24 has a certain inclination angle, the baffle 24 is not perpendicular to the high-pressure box 23, resulting in a relatively large force required to push the baffle 24. This prevents the baffle 24 from being pushed open by the gas before the sauce is cleared due to pressure when the pipeline of the suction cup body 121 is blocked, thereby causing the sauce not to be cleared and resulting in instability in sucking the dried meat slices next time.

[0029] Working principle and usage process of the present invention: When using this device, first connect the meat jerky conveyor line 3 and the meat jerky packaging line 4 to an external power supply and then start them. At the same time, connect the exhaust fan 22 to an external power supply and then start it. The exhaust fan 22 will extract air from the inside of the negative pressure box 21 to the outside. The meat jerky that has been cut through the previous process will be placed on the surface of the meat jerky conveyor line 3 and conveyed to the lower part of the suction cup main body 121. Then connect the motor 15 to an external power supply and start it. The output shaft of the motor 15 will drive the limit disk 16 to rotate. The rotation of the limit disk 16 will drive the limit post B115 to rotate around the center of the limit disk 16. When the limit post B115 rotates to a certain position, it will insert into the positioning groove A. Then it will drive the driven disk B111 to rotate around the linkage shaft 116 through the limit post B115. When the driven disk B111 rotates, the limit shell 11 will drive the positioning block 13 to rotate inside the negative pressure box 21. When the limit post B115 drives the driven disk B111 to rotate by 90 degrees, it will disengage from the inside of the positioning groove A. At this time, the curved groove A will fit with the positioning disk B114, and the driven disk B111 will be limited by the positioning disk B114. At this time, the support arm 12 is in a stopped state. The limit disk 16 continues to rotate, and the limit post A18 will insert into the positioning groove B, thereby driving the driven disk A19 to rotate. When the driven disk A19 rotates, it will drive the limit gear ring 123 to rotate. When the linkage rod 124 does not move and the limit gear ring 123 rotates, the limit gear ring 123 will squeeze the linkage rod 124 due to its shape, indirectly causing the support arm 12 to move into the linkage hole 125, and the spring B126 will be compressed. The linkage rod 124 will move straight up and down due to the limitation of the limit groove 113 on it until the suction cup main body 121 rotates to a certain angle, and the limit post A18 will disengage from the inside of the positioning groove B. The positioning disk A17 will limit the driven disk A19 through the curved groove B. At this time, the linkage rod 124 will be at the lowest point of the limit gear ring 123. Just when the suction cup main body 121 contacts the pork jerky, due to the negative pressure box 21, the suction cup main body 121 will suck the meat jerky. The limit disk 16 continues to rotate, and the second limit post A18 will insert into another positioning groove B again, thereby driving the driven disk A19 to rotate. The driven disk A19 will drive the limit gear ring 123 to rotate again. Through the elastic potential energy of the spring B126, the linkage rod 124 will slide upward on the surface of the limit gear ring 123, and the support arm 12 will drive the meat jerky to move upward. Repeating this process realizes the suction of the meat jerky, avoiding the disadvantages of low efficiency and inability to quantify of traditional manual methods, and also avoiding the possibility of damaging the meat jerky by traditional mechanical claws. When the driven disk B111 rotates, the suction cup main body 121 meshes with the air passing hole 119 to drive the linkage shaft 116 to rotate, so that the suction cup main body 121 and the limit shell 11 rotate synchronously, which can avoid the situation where the linkage rod 124 rotates while the limit gear ring 123 does not rotate, and the shape of the limit gear ring 123 limits the linkage rod 124, causing the linkage rod 124 to move up and down while rotating, thus creating unnecessary vibrations.Increases the risk of the meat jerky falling during transportation. When the positioning cylinder 117 rotates, it will drive the limit gear ring 123 to rotate through the linkage shaft 116. Due to the ratchet 118, the driven disk B111 will not rotate, which will not affect the movement of the support arm 12. When one of the support arms 12 rotates towards the meat jerky packaging line 4, the connecting cylinder 128 will slide on the surface of the conical piece. Due to the shape of the conical piece, the connecting cylinder 128 will also rise inside the receiving groove 127 during rotation until the suction cup body 121 stops directly above the meat jerky packaging line 4. At this time, the connecting cylinder 128 is at the highest point of the conical piece. When the connecting cylinder 128 moves, the corrugated plates 129 on both sides will contract and expand to different degrees along with the movement of the connecting cylinder 128. Sealing slide rails are provided on both sides of the corrugated plate 129 for the contraction and expansion of the corrugated plate 129, achieving the sealing of the linkage hole 125 while not affecting the movement of the connecting cylinder 128. As the limit gear ring 123 rotates, the support arm 12 will move downward inside the linkage hole 125. Eventually, the support arm 12 will block the connection end with the connecting cylinder 128, making it impossible for the connecting cylinder 128 to inhale air from the inside of the support arm 12 through the linkage hole 125, so that the meat jerky detaches from the surface of the suction cup body 121. Since the support arm 12 moves downward when the connecting cylinder 128 is closed, the detachment height of the meat jerky is relatively low, preventing the meat jerky from deviating in position due to wind resistance during falling caused by height problems, resulting in difficulties in packaging. Due to the fact that taking and placing the meat jerky are simultaneous, the limit ring A130 is only provided on the side close to the meat jerky packaging line 4, which is convenient for closing the air and placing the meat jerky, and will not affect taking and transporting the meat jerky at all. When the support arm 12 blocks the connection end of the connecting cylinder 128, it will squeeze the limit plug 110, and the limit plug 110 will move into the inside of the connecting cylinder 128, and the spring A122 will be compressed until the limit plug 110 seals the inside of the connecting cylinder 128, preventing the support arm 12 from being unable to seal the connecting cylinder 128, and the remaining gas will affect the accuracy of placing the meat jerky. When the suction cup body 121 rotates again after putting down the meat jerky, the moving tube 211 will slide on the surface of the limit ring B210 until it contacts the convex block. The moving tube 211 will be squeezed and move upward inside the air passing hole 119, and the spring C29 will be compressed until the moving tube 211 rotates 90 degrees. Then, the moving tube 211 will be at the highest point of the convex block, and the air inlet hole 28 will enter the inside of the air passing hole 119 and be parallel to the ring groove 27. The gas inside the high-pressure box 23 will finally pass through the trachea 26 and then through the moving tube 211 and be discharged from the inside of the suction cup body 121. This gas will clean the pipeline inside the suction cup body 121 to prevent the sauce from clogging the pipeline, and the removed sauce will finally fall into the inside of the collection box 212, achieving collection. Therefore, the convex block is only provided on the side close to the collection box 212, so it will not affect other suction cup bodies 121. Since there is a spacing for each cleaning, in order to prevent the pressure inside the high-pressure box 23 from being too high, a baffle 24 is provided.When the internal pressure of the high-pressure box 23 is too high, the baffle 24 will be pushed by the gas to rotate on the surface of the bearing seat, thereby releasing the internal pressure of the high-pressure box 23 and preventing risks such as explosion. Since one side of the baffle 24 is set with a certain inclination angle, the baffle 24 is not perpendicular to the high-pressure box 23, resulting in a relatively large force required to push the baffle 24. This prevents the baffle 24 from being pushed open by the gas before the sauce is cleared due to pressure when the pipeline of the suction cup body 121 is blocked, thus causing the sauce not to be cleared and leading to instability in sucking the dried meat slices next time.
