Description

Technical Field

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

[0002] Meat jerky is a flaked meat product made from marinated and roasted pork or beef. The earliest meat jerky in my country refers to a reddish-colored leisure pork product made in southern Fujian and Chaoshan. Pork jerky is made from marinated and roasted pork into a flaked meat product. Its brownish-red color, compact texture, and ease of storage and transportation make it easy to transport. Because the meat jerky is marinated and coated with sauce, it needs to be protected with packaging to prevent contamination from the outside world.

[0003] However, traditional meat jerky packaging relies on manual filling by workers, which not only leads to low efficiency due to the workers' working hours, but also makes it difficult to ensure the same amount of meat jerky in each package due to manual filling. When the existing robotic arm fills the meat jerky, the sauce on the surface of the meat jerky will stick to the surface of the robotic claw every time it grabs the meat jerky. When the meat jerky is put down, the sticky nature of the sauce will cause the meat jerky to deviate from the expected position. Over time, the sauce will become thicker, making it difficult to grab the meat jerky. In addition, the meat jerky may be damaged because the distance between them is the same as when it was first grabbed.

[0004] In order to solve the above problems, the present application proposes a quantitative feeding device for single-piece packaging of pork jerky. Summary of the Invention

The surface of the limiting disk 16 is fixedly connected with the positioning disk A17, and a limiting tooth ring 123 is provided inside the limiting shell 11. The linkage shaft 116 passes through the limiting shell 11 and is fixedly connected to the limiting tooth ring 123. The interior of the positioning block 13 is evenly provided with linkage holes 125, and a support arm 12 is provided 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 provided inside the linkage hole 125. The two ends of the spring B126 are respectively fixedly connected to the positioning block 13 and the support arm 12. Each support arm 12 is away from one end of the positioning block 13. The ends are fixedly connected to the suction cup body 121, and each support arm 12 is fixedly connected to a linkage rod 124 on one side close to the limit shell 11. The limit shell 11 is provided with a limit groove 113 at the position of the linkage rod 124. The linkage rod 124 passes through the limit shell 11 through the limit groove 113 and is slidably connected to it. The linkage rod 124 and the limit gear ring 123 fit together. A number of curved grooves A are evenly provided on the surface of the driven disk B111. The positioning disk B114 fits together with the driven disk B111 through the curved groove A. A number of curved grooves B are evenly provided on the surface of the driven disk A19. The positioning disk A17 fits together with the driven disk A19 through the curved groove B, and two limit columns A18 are located on one side of the limit column B115.

[0037] In this embodiment: when using the device, first connect the meat jerky conveyor line 3 and the meat jerky packaging line 4 to the external power supply and then start them, and at the same time connect the exhaust fan 22 to the 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 the 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 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 will drive 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 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, 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, and When the linkage rod 124 does not move and 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. 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 be disengaged 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 the inside of another positioning groove B again to drive the driven plate A19 to rotate. The driven plate A19 will again drive the limit gear 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 gear ring 123, and the support arm 12 will move the meat jerky upward. This cycle repeats itself to achieve the suction of the meat jerky, avoiding the low efficiency and inability to quantify of traditional manual labor, and also avoiding the possibility of traditional mechanical claws damaging the meat jerky.

[0038] Going further:

[0039] In an optional embodiment, the driven disk B111 and the linkage shaft 116 are rotatably connected, and the surface of the linkage shaft 116 located inside the driven disk B111 is fixedly connected to a ratchet 118. The interior of the driven disk B111 is rotatably connected to a ratchet 120 via a rotating shaft. The ratchet 120 and the ratchet 118 are meshed and connected, and a torsion spring is wrapped around the surface of the rotating shaft, so that the limit shell 11 and the limit gear ring 123 can rotate separately.

[0040] In this embodiment: when the driven disk B111, the suction cup body 121 and the air hole 119 engage with each other to drive the linkage shaft 116 to rotate, so that the suction cup body 121 and the limiting shell 11 rotate synchronously, which can avoid that when the linkage rod 124 rotates, the limiting tooth ring 123 does not rotate. The linkage rod 124 is limited by the shape of the limiting tooth ring 123, causing the linkage rod 124 to move up and down when rotating, thereby creating unnecessary shaking and increasing the risk of the jerky falling during transportation. When the positioning cylinder 117 rotates, it will drive the limiting tooth ring 123 to rotate through the linkage shaft 116, and the driven disk B111 will not rotate due to the ratchet 118, and will not affect the movement of the support arm 12.

[0041] Going further:

[0042] In an optional embodiment, a receiving groove 127 is provided inside the positioning block 13, and the receiving groove 127 and the linkage hole 125 are mutually connected. A connecting tube 128 is provided inside the receiving groove 127, and the connecting tube 128 is slidably connected to the positioning block 13 through the receiving groove 127. The surface of the connecting tube 128 is fixedly connected to the bellows 112, and an air hole 119 is provided inside the positioning block 13. The end of the bellows 112 away from the connecting tube 128 is inserted into the air hole 119, and a limiting ring A130 is provided inside the receiving groove 127. The limiting ring A130 is connected to the positioning block 1 3 Rotational connection, the limiting ring A130 is fixedly connected to the negative pressure box 21 through the connecting rod, and two corrugated plates 129 are symmetrically fixedly connected to the surface of the connecting cylinder 128. The end of the corrugated plate 129 away from the connecting cylinder 128 is fixedly connected to the positioning block 13. The upper surface of the limiting ring A130 is fixedly connected with a conical piece, 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 can move up and down. The corrugated plate 129 is located at the connection point between the accommodating groove 127 and the linkage hole 125, so that the connecting cylinder 128 can remain sealed while moving.

[0043] In this embodiment: when one of the support arms 12 rotates toward the meat jerky packaging line 4, the connecting cylinder 128 will slide on the surface of the conical piece, and due to the shape of the conical piece, the connecting cylinder 128 will also rise inside the accommodating groove 127 when rotating, until the suction cup body 121 is located directly above the meat jerky packaging line 4 and stops. 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 shrink and expand to varying degrees as the connecting cylinder 128 moves. Sealing slide rails are provided on both sides of the corrugated plate 129 for shrinking and expanding the corrugated plate 129, so that the linkage hole 125 can be sealed without affecting the movement of the connecting cylinder 128. As the limiting tooth ring 123 rotates, the support arm 12 will move downward inside the linkage hole 125, and eventually the support arm 12 will block the connection end with the connecting tube 128, so that the connecting tube 128 cannot absorb air from the inside of the support arm 12 through the linkage hole 125, thereby causing the meat jerky to detach from the surface of the suction cup body 121. Since the support arm 12 moves downward when the connecting tube 128 is closed, the detachment height of the meat jerky is lower, which prevents the meat jerky from deviating from its position due to wind resistance when falling due to height problems, resulting in difficulties in packaging. Since the meat jerky is taken and placed at the same time, the limiting ring A130 is only set 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 the taking and conveying of the meat jerky at all.

[0044] Going further:

[0045] In an optional embodiment, the interior of the connecting cylinder 128 is slidably connected to the limiting plug 110, and a spring A122 is provided inside the connecting cylinder 128. The two ends of the spring A122 are respectively fixedly connected to the limiting plug 110 and the connecting cylinder 128. The end of the limiting plug 110 away from the connecting cylinder 128 is inserted into the interior of the linkage hole 125 and fits together with the support arm 12.

[0046] In this embodiment: when the support arm 12 blocks the connecting end of the connecting tube 128, it will squeeze the limit plug 110, and the limit plug 110 will move toward the inside of the connecting tube 128. The spring A122 will be compressed until the limit plug 110 seals the inside of the connecting tube 128, preventing the support arm 12 from being unable to seal the connecting tube 128. The residual gas will affect the accuracy of placing the jerky.

[0047] Going further:

[0048] In an optional embodiment, the exhaust end of the exhaust fan 22 is fixedly connected to the high-pressure box 23, the surface of the high-pressure box 23 is fixedly connected to the air pipe 26, the positioning block 13 is inserted into the surface of the negative pressure box 21 and an annular groove 27 is provided, the end of the air pipe 26 away from the high-pressure box 23 passes through the negative pressure box 21 and is inserted into the inside of the annular groove 27, the interior of the air hole 119 is provided with a movable tube 211, the movable tube 211 is slidably connected to the positioning block 13 through the air hole 119, the interior of the air hole 119 is provided with a spring C29, the two ends of the spring C29 are fixedly connected to the movable tube 211 and the positioning block 13 respectively, and the internal fixed connection of the negative pressure box 21 is limited. The positioning ring B210, the movable tube 211 and the limiting ring B210 fit together, and each movable tube 211 is provided with an air inlet 28 on the side facing the annular groove 27. The positioning block 13 is located on one side of the air pipe 26 and is provided with a collection box 212. The collection box 212 is located below the suction cup body 121. The upper surface of the limiting ring B210 is fixedly connected with a convex block, and the convex block is located on the side close to the air pipe 26, so that when the movable tube 211 is located on the surface of the convex block, the movable tube 211 moves upward, and the air inlet 28 is no longer affected by the negative pressure inside the negative pressure box 21. The air inlet 28 is aligned with the annular groove 27, so that the air pipe 26 and the air inlet 28 are connected to each other.

[0049] In this embodiment: when the suction cup body 121 puts down the jerky and rotates again, 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 hole 119. The spring C29 will be compressed until the moving tube 211 rotates ninety degrees. The moving tube 211 will be at the highest point of the convex block, and the air inlet 28 will enter the interior of the air hole 119 and be parallel to the annular groove 27. The gas inside the high-pressure box 23 will pass through the air pipe 26 and finally through the moving tube 211 and then be discharged from the interior 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 cleared sauce will eventually fall into the interior of the collection box 212 to achieve collection. Therefore, the convex block is only arranged on one side close to the collection box 212, so it will not affect other suction cup bodies 121.

[0050] Going further:

[0051] In an optional embodiment, a release hole is opened on the surface of the high-pressure box 23, and a filter 25 is installed inside the release hole. The side of the high-pressure box 23 located at the release hole is rotatably connected to a baffle 24 through a bearing seat, and the baffle 24 is inserted inside the release hole.

[0052] In this embodiment: Since there is a spacing between each cleaning, in order to prevent the internal pressure of 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 has a certain inclination angle, the baffle 24 is not perpendicular to the high-pressure box 23, resulting in a larger force used to push the baffle 24, preventing the gas from pushing the baffle 24 open when the pipe of the suction cup body 121 is blocked due to pressure before the sauce is cleared, thereby causing the sauce to not be cleared, resulting in instability in the next suction of the jerky.

[0053] The working principle and use process of the present invention: When using the device, first connect the meat jerky conveyor line 3 and the meat jerky packaging line 4 to the external power supply and then start them, and at the same time connect the exhaust fan 22 to the external power supply and then start them. The exhaust fan 22 will draw air out from the inside of the negative pressure box 21. 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. Then connect the motor 15 to the external power supply and then start it. The output shaft of the motor 15 will drive the limit plate 16 to rotate. 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. 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 drive the driven plate B111 through the limit column B115 to rotate with the linkage shaft 116 The driven disc B111 is rotated about the axis. When the driven disc 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 disc B111 to rotate to ninety degrees, it will detach from the inside of the positioning slot A. At this time, the curved slot A will fit with the positioning disc B114, and the driven disc B111 will be limited by the positioning disc B114. At this time, the support arm 12 is in a stopped state, the limiting disc 16 continues to rotate, and the limiting column A18 will be inserted into the inside of the positioning slot B, thereby driving the driven disc A19 to rotate. When the driven disc A19 rotates, it will drive the limiting gear ring 123 to rotate. When the linkage rod 124 does not move and the limiting gear ring 123 rotates, the limiting gear ring 123 will squeeze the linkage rod 124 due to its shape, indirectly making the support arm 1 2 moves to the inside of the linkage hole 125, the spring B126 will be compressed, and 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 disengage 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. Just after the suction cup body 121 and the pork jerky come into contact with each other, the suction cup body 121 will suck the pork jerky due to the negative pressure box 21, and the limiting plate 16 continues to rotate. The second limiting column A18 will be inserted into the inside of another positioning groove B again to drive the driven plate A19 to rotate, and the driven plate A19 will drive the limiting tooth ring 123 to rotate again, through the spring The elastic potential energy of B126 makes the linkage rod 124 slide upward on the surface of the limiting tooth ring 123, and the support arm 12 will move the meat jerky upward, and repeat this process over and over again, thus realizing the absorption of the meat jerky, avoiding the disadvantages of low efficiency and inability to quantify the meat jerky by traditional manual labor, and also avoiding the possibility of traditional mechanical claws damaging the meat jerky. When the driven disk B111 is engaged with the air hole 119 through the suction cup body 121, the linkage shaft 116 is driven to rotate, so that the suction cup body 121 and the limiting shell 11 rotate synchronously, which can avoid that the limiting tooth ring 123 does not rotate when the linkage rod 124 rotates. The linkage rod 124 is limited by the shape of the limiting tooth ring 123, causing the linkage rod 124 to move up and down when rotating, thereby creating unnecessary shaking.The risk of the meat jerky falling during transportation is increased. When the positioning cylinder 117 rotates, the limiting gear ring 123 will be driven to rotate through the linkage shaft 116, and the driven disk B111 will not rotate due to the ratchet 118, and will not affect the movement of the support arm 12. When one of the support arms 12 rotates toward the meat jerky packaging line 4, the connecting cylinder 128 will slide on the surface of the cone piece, and due to the shape of the cone piece, the connecting cylinder 128 will also rise inside the accommodating groove 127 when rotating until the suction cup body 121 is located directly above the meat jerky packaging line 4 and stops. At this time, the connecting cylinder 128 is located at the highest point of the cone piece. When the connecting cylinder 128 moves, the corrugated plates 129 on both sides will shrink and expand to varying degrees with the movement of the connecting cylinder 128. The two sides of the corrugated plate 129 are provided with sealing slide rails for the contraction and expansion of the corrugated plate 129, so that the linkage hole 125 can be sealed without affecting the movement of the connecting cylinder 128. As the limiting tooth ring 123 rotates, the support arm 12 will move down inside the linkage hole 125, and finally the support arm 12 will block the connection end with the connecting cylinder 128, so that the connecting cylinder 128 cannot absorb air from the inside of the support arm 12 through the linkage hole 125, thereby causing the meat jerky to detach from the surface of the suction cup body 121. Because the support arm 12 moves down when the connecting cylinder 128 is closed, the detachment height of the meat jerky is low, which prevents the meat jerky from deviating from the position of the meat jerky due to wind resistance when falling due to height problems, resulting in difficulty in packaging. Because of the simultaneous operation, the limiting ring A130 is only arranged 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 the taking and conveying of the meat jerky at all. When the support arm 12 blocks the connecting end of the connecting tube 128, the limiting plug 110 will be squeezed, and the limiting plug 110 will move toward the inside of the connecting tube 128. The spring A122 will be compressed until the limiting plug 110 seals the inside of the connecting tube 128, preventing the support arm 12 from being unable to seal the connecting tube 128. The residual gas will affect the accuracy of placing the meat jerky. When the suction cup body 121 puts the meat jerky down and rotates again, the moving tube 211 will slide on the surface of the limiting ring B210 until it contacts the convex block. The moving tube 211 will be squeezed and inserted into the air hole 119. The upper portion moves upward, and the spring C29 will be compressed until the moving tube 211 rotates ninety degrees, at which point the moving tube 211 will be at the highest point of the convex block, and the air inlet 28 will enter the interior of the air hole 119 and be parallel to the annular groove 27. The gas inside the high-pressure box 23 will pass through the air pipe 26 and finally through the moving tube 211 to be discharged from the interior of the suction cup body 121. This gas will clean the pipe inside the suction cup body 121 to prevent the sauce from clogging the pipe, and the cleared sauce will eventually fall into the collection box 212 to achieve collection. Therefore, the convex block is only provided on one side close to the collection box 212, so it will not affect other suction cup bodies 121. Since there is a spacing between each cleaning, a baffle 24 is provided to prevent the internal pressure of the high-pressure box 23 from being too high.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 internal pressure of the high-pressure box 23 and preventing the risk of explosion. Because the baffle 24 is set at a certain angle, it is not perpendicular to the high-pressure box 23, which causes the force required to push the baffle 24 to be greater. This prevents the gas pressure from pushing the baffle 24 open before the sauce is removed when the pipe of the suction cup body 121 is blocked, resulting in the sauce not being removed and causing instability in the next jerky suction.
