Description

Technical Field

[0001] The present invention relates to the technical field of conveying equipment, and more particularly to a hanging conveying device for pre-processing fresh meat for making meat jerky. Background Art

[0002] Suspended conveyors are automated devices that suspend and transport items via components such as chains and hooks. They feature high space utilization, flexible transport paths, and adaptability to complex working conditions. Their core structure typically includes a drive unit, conveyor chains, suspension hooks, a track system, and a control system, enabling continuous or intermittent transport of items. They are widely used in industries such as food processing, logistics and warehousing, and machinery manufacturing. In the pre-processing of fresh meat for jerky production, suspended chains transport pork to various processing areas, such as cooling rooms, acid draining rooms, spray rooms, and cutting stations, enabling automated transport.

[0003] Before hanging the pork, a hole must be made manually using a knife or a sharp hook. The operation requires precise positioning and forceful puncture. The worker needs to repeatedly bend over or lift heavy objects. After the hole is manually made, the hook must be accurately inserted into the hole. Due to the deviation of the hole position and the difficulty in positioning the hook, it is impossible to automate the hanging of pork with the help of manipulators and other equipment. This is time-consuming and labor-intensive, and the workers are tired. Therefore, it is necessary to provide a conveying device that does not require manual pre-drilling of holes and can automatically complete the hanging of fresh meat with the help of manipulators and other equipment. In view of this, we propose a hanging conveying device for pre-processing fresh meat for making jerky. Summary of the Invention

[0054] The chain 4 is arranged below the slide rail 3 and connected to the output end of the rotating mechanism 2; the frame 1, rotating mechanism 2, slide rail 3 and chain 4 of the present invention are all prior arts and are not described in detail here.

[0055] Several hangers 5 are evenly arranged and fixedly connected to the links of the chain 4. A swivel seat 51 is fixedly provided at one end of the hanger 5 close to the rotating mechanism 2. A movable arc groove 52 is provided at one end of the hanger 5 away from the rotating mechanism 2. A through hole is provided at the arc center of the movable arc groove 52. Movable column grooves 53 are provided at both ends of the through hole relative to the movable arc groove 52. A snap-on ball block 54 is movably connected to the movable column groove 53. The snap-on ball block 54 is elastically connected to the movable column groove 53 via a spring A55.

[0056] A rib group A and a rib group B are fixed on both sides of the top of the movable arc groove 52. The rib group A and the rib group B are arranged alternately. The rib group A includes several ribs A521 arranged in an arc-shaped structure with equal spacing, and the rib group B includes several ribs B522 arranged in an arc-shaped structure with equal spacing.

[0057] A gear set 6 is mounted on the rotating seat 51. The gear set 6 includes a coupling 61, which is rotatably mounted on the rotating seat 51. The top end of the coupling 61 passes through the links of the chain 4 and extends into the slide rail 3, where a gear A62 is fixedly mounted. The coupling 61 is rotatably connected to the links of the chain 4. The gear A62 meshes with the two racks 31. The coupling 61 is movably connected to the slide rail 3 via a roller assembly 63. A bevel gear B64 is fixedly mounted on the bottom end of the coupling 61. Through the above arrangement, the present invention enables a robot or other device to deliver pork to an appropriate location when the hanging seat 5 passes one of the racks 31. When the hanging seat 5 passes one of the racks 31, the gear A62 rotates. When the hanging seat 5 passes one of the racks 31, the gear A62 rotates in the opposite direction.

[0058] A perforated suspension mechanism 7 is provided on the suspension seat 5. The perforated suspension mechanism 7 includes a rotating shaft A71 and an auxiliary component 78. The rotating shaft A71 is rotatably arranged on the through hole. A snap-in ball groove 711 is provided on the rotating shaft A71. The snap-in ball groove 711 is snap-fitted with the snap-in ball block 54. A bevel gear C72 is fixed to one end of the rotating shaft A71. The bevel gear C72 is meshed with the bevel gear B64. A connecting rod 73 is fixed to the other end of the rotating shaft A71. A swivel 74 is fixed to the connecting rod 73. A rotating shaft B75 is rotatably provided on the swivel 74. The rotating shaft B75 is movably connected to the movable arc groove 52 through a movable block 76. A perforated suspension component 77 is fixed to the end of the rotating shaft B75 away from the movable arc groove 52. The auxiliary component 78 is fixed to the suspension seat 5. When the movable block 76 moves to the bottom end of the movable arc groove 52, the perforated suspension component 77 is connected to the auxiliary component 78 to form a triangular suspension structure. Through the above-mentioned arrangement, the present invention enables the rotation of gear A62 to drive the rotation shaft A71, connecting rod 73, swivel 74 and rotation shaft B75, so that the movable block 76 moves in the movable arc groove 52. When the movable block 76 moves from the bottom end of the movable arc groove 52 to the top end, the perforation suspension assembly 77 is disengaged from the auxiliary assembly 78 to form a hanging state to be perforated. The card ball groove 711 is engaged with one of the card ball blocks 54 to limit the position, preventing the rotating shaft A71 from rotating on its own. When the movable block 76 moves from the top end of the movable arc groove 52 to the bottom end, the card ball groove 711 is engaged with the other card ball block 54 to limit the position, preventing the rotating shaft A71 from rotating on its own. The perforation suspension assembly 77 rotates to perforate the pork. The perforation suspension assembly 77 is connected with the auxiliary assembly 78 to form a triangular suspension structure, realizing the suspension automation of the suspension conveyor.

[0059] The movable block 76 is columnar, and a plurality of grooves 761 are formed on the surface of the movable block 76 in an annular structure with equal spacing. The protrusions A521 and the protrusions B522 are movably engaged with the grooves 761 .

[0060] The perforated suspension assembly 77 includes a mounting block A771 and a perforated hook unit. The mounting block A771 is fixed on the rotating shaft B75. A support rod A772 is fixed on the top of the mounting block A771. The top of the support rod A772 is rotatably connected to the support rod B773. A movable groove 774 is provided on the top of the support rod B773. A movable shaft 775 is movably provided on the movable groove 774. The movable shaft 775 is fixedly connected to the hanger 5. The perforated hook unit is arranged on the mounting block A771. The present invention adopts the structural design of the perforated hanging assembly 77, the movable block 76 and the movable arc groove 52, so that when the movable block 76 moves at the top of the movable arc groove 52, the convex strips A521 and the convex strips B522 are alternately engaged with the groove 761 to make the mounting block A771 and the perforated hook unit rotate back and forth, and the movable groove 774 moves relative to the movable shaft 775, making it more convenient for the perforated hook unit to perforate pork, ensuring that the perforated hook unit can penetrate the pork, further reducing manual operation, saving time and effort, and further solving the technical problem of time-consuming and labor-intensive pre-processing of fresh meat for making meat jerky using a suspended conveying device.

[0061] The mounting block A771 has four centripetal slots 776 formed in a circular structure with equal spacing at one end near the auxiliary assembly 78. A slider 778 is slidably connected to the centripetal slots 776. The slider 778 is elastically connected to the centripetal slots 776 via a spring B779.

[0062] The perforated hook unit includes four perforated hooks 770 , which are respectively fixed on four sliders 778 .

[0063] The perforated hook 770 includes an inverted arc portion 7701, which is fixed on the slider 778. A positive arc portion 7702 is fixed on the inverted arc portion 7701. The positive arc portion 7702 is tapered at one end away from the inverted arc portion 7701, and the center line of the positive arc portion 7702 coincides with the axis center line of the rotating shaft A71.

[0064] The auxiliary assembly 78 includes a support rod C781, which is fixed to the movable shaft 775. A mounting block B782 is fixed to the bottom end of the support rod C781. The mounting block B782 has four slots in a circular structure with equal spacing near the end of the positive arc portion 7702. The slots are plugged into the positive arc portion 7702.

[0065] The slot includes a guide slot 783, which has a plug-in arc slot 784 at one end away from the positive arc portion 7702. Through the above arrangement, the present invention allows the guide slot 783 to guide the positive arc portion 7702 when the perforated suspension assembly 77 is connected to the auxiliary assembly 78, so that the reverse arc portion 7701 drives the slider 778 to slide eccentrically on the centripetal slide 776, allowing the four perforated hooks 770 to expand the holes through which the pork is pierced to form a flow channel. This facilitates the outflow of blood and water from the perforated pork during the pretreatment of pork for jerky production, reduces the subsequent manual processing process, saves time and effort, and further solves the technical problem of time and effort required when using a suspended conveyor device to pretreatment fresh meat for jerky production.

[0066] In addition, the present invention provides an inverted arc portion 7701, and four inverted arc portions 7701 form a hanging structure, so that the four perforating hooks 770 expand the holes through which the pork is pierced to form a flow channel in the shape of an inverted arc, which is convenient for the outflow of blood and water in the holes in the pork, saving time and effort, and further solving the technical problem of time-consuming and labor-intensive pre-processing of fresh meat for making meat jerky by a hanging conveying device.

[0067] As another embodiment of the present invention, two racks 31 can also be fixedly mounted at both ends of the slide rail 3 relative to the input and output ends of the suspended conveyor device. With this arrangement, when the hanger 5 passes the rack 31 at the input end of the suspended conveyor device, the gear A62 rotates, causing the perforated suspension assembly 77 to disengage from the auxiliary assembly 78, forming a state to be perforated. When the movable block 76 moves at the top of the movable arc groove 52, the protrusions A521 and B522 alternately engage with the grooves 761 of the movable block 76, and the perforated hook 770 rotates back and forth to facilitate the removal of the pork.

[0068] Working Principle: This embodiment provides a suspended conveyor device for pre-processing fresh meat for making jerky. During use, the chain 4 is driven by the rotating mechanism 2 to circulate. When the hanger 5 passes the staggered racks 31 at both ends of the slide rail 3, the gear A62 engages with the racks 31, driving the connecting shaft 61 to rotate forward and reverse. The connecting shaft 61 is driven by the bevel gears B64 and C72, driving the rotating shaft A71 to rotate. The rotating shaft A71 drives the connecting rod 73, the rotating ring 74, and the rotating shaft B75 to move, causing the movable block 76 to slide within the movable arc groove 52.

[0069] When the movable block 76 moves from the bottom end of the movable arc groove 52 to the top end, the perforation suspension assembly 77 and the auxiliary assembly 78 are separated to form a state of suspension to be perforated, and the engaging ball groove 711 is engaged with one of the engaging ball blocks 54 to prevent the rotation shaft A71 from rotating. When the movable block 76 moves from the top end of the movable arc groove 52 to the bottom end, the engaging ball groove 711 is engaged with the other engaging ball block 54 to prevent the rotation shaft A71 from rotating. The perforation suspension assembly 77 rotates to perforate the pork. The perforation suspension assembly 77 and the auxiliary assembly 78 are connected to form a triangular suspension structure, realizing the suspension automation of the suspension conveyor device.

[0070] The convex strips A521 and B522 are alternately engaged with the grooves 761 to allow the mounting block A771 and the piercing hook unit to reciprocate. The movable groove 774 moves relative to the movable shaft 775, making it easier for the piercing hook unit to pierce the pork and ensuring that the piercing hook unit can penetrate the pork.

[0071] When the perforated hanging assembly 77 is connected to the auxiliary assembly 78, the guide groove 783 guides the positive arc portion 7702, so that the reverse arc portion 7701 drives the slider 778 to slide eccentrically on the centripetal slide groove 776, so that the four perforated hooks 770 expand the holes pierced through the pork to form a reverse arc flow channel, facilitating the drainage of blood.

[0072] In addition, the two racks 31 can also be fixed at both ends of the slide rail 3 relative to the input end and output end of the suspension conveyor device. When the hanger 5 passes the rack 31 at the input end position of the suspension conveyor device, the gear A62 rotates to disengage the perforated suspension component 77 and the auxiliary component 78 to form a hanging state to be perforated. When the movable block 76 moves at the top of the movable arc groove 52, the convex strips A521 and the convex strips B522 alternately engage with the groove 761 of the movable block 76, and the perforated hook 770 rotates back and forth to facilitate shaking out the pork.

[0073] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
