Description

Technical Field

[0001] This invention relates to the field of meat curing technology, and more particularly to a tumbling device for meat curing and processing. Background Technology

[0002] When marinating meat, the marinade should first be applied or sprinkled on the surface of the meat product, and then the meat should be rubbed to allow the marinade to penetrate the meat better, thereby increasing the marinating effect.

[0003] A search revealed a Chinese patent publication number CN112806539A, which discloses a kneading device for food processing. The device includes a support base plate for supporting the equipment, two support side plates, and a kneading and salting mechanism for salting meat. The support base plate has two support side plates fixedly connected to its surface. The two support side plates are symmetrically distributed about the center line of the support base plate surface. The kneading and salting mechanism is disposed on the two support side plates.

[0004] The aforementioned patent has the following shortcomings: it can only use the conveyor belt to achieve the kneading effect, but it cannot pat the meat during kneading, which makes the rate at which the marinade penetrates into the meat slower.

[0005] Therefore, the present invention proposes a tumbling device for meat marinating and processing. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a tumbling device for meat marinating and processing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A tumbling device for meat marinating and processing includes a base. The top outer wall of the base is fixed with a container barrel by bolts. The bottom inner wall of the container barrel is provided with a second kneading board. The top outer wall of the base is fixed with a gantry frame by bolts. The top of the gantry frame is connected to a lifting ring seat through a lifting mechanism. The inside of the lifting ring seat is connected to a transmission ring through a rotation drive mechanism. The inner side of the lifting ring seat and the outer wall of the transmission ring are connected to the same connecting ring. The bottom of the connecting ring is fixed with a kneading board that cooperates with the second kneading board. The outer circumferential wall of the transmission ring is provided with a flat key rib, the inner circumferential wall of the connecting ring is provided with a keyway that fits with the flat key rib with clearance, the inner circumferential wall of the lifting ring seat is provided with a wave-shaped limiting groove, and the outer circumferential wall of the connecting ring is fixed with a transmission protrusion that fits with the wave-shaped limiting groove for movable limiting.

[0008] Preferably, the rotary drive mechanism includes a motor, a main shaft, and a gear ring. The motor is fixed above the lifting ring seat via a frame. The main shaft is driven by the output shaft of the motor via a dual-position clutch assembly. A sun gear is connected to the outer wall of the main shaft via a key. Multiple planet gears mesh with the opposite side of the gear ring and the sun gear. The planet gears are rotatably connected to the inner wall of the lifting ring seat via a rotating shaft. The gear ring is also rotatably connected to the inner wall of the lifting ring seat. The bottom of the gear ring is fixed to the top outer wall of the transmission ring via a connecting ring II.

[0009] Furthermore: the second kneading board is rotatably connected to the inner bottom of the container, and the main shaft moves through the first kneading board.

[0010] Based on the aforementioned scheme: a transmission head is welded to the bottom outer wall of the main shaft, and a transmission groove matching the transmission head is opened on the inner wall of the second kneading plate.

[0011] A better option among the aforementioned solutions is that the top inner wall of the lifting ring seat and the bottom side wall of the connecting ring are both provided with heat dissipation holes, and a simple one-way valve is provided on the inner wall of the heat dissipation holes.

[0012] As a further aspect of the present invention: the simple one-way valve passage direction in the lifting ring seat is from the inside of the lifting ring seat to the outside of the lifting ring seat, and the simple one-way valve passage direction in the connecting ring one is from the outside of the connecting ring one to the inside of the connecting ring one.

[0013] Meanwhile, the simple one-way valve includes a perforated plate fixed to the inner wall of the heat dissipation hole and a plurality of fan-shaped flexible pads fixed to the inner wall of the heat dissipation hole. The plurality of fan-shaped flexible pads are arranged in a circular array and can form a complete circular plane. The perforated plate and the fan-shaped flexible pads are in contact with each other.

[0014] As a preferred embodiment of the present invention, both the transmission ring and the connecting ring II have uniform through holes on their side walls.

[0015] Meanwhile, the lifting mechanism includes a driving pulley, two driven pulleys, and two lead screws. The lead screws are rotatably connected to the top of the lifting ring seat and are threaded to the inner wall of the gantry frame. The driven pulleys are keyed to the outer wall of the lead screws. The driving pulleys are driven and engaged with the outer wall of the motor output shaft through a dual-position clutch assembly. The outer walls of the driving pulleys and driven pulleys are engaged with the same synchronous belt.

[0016] As a preferred embodiment of the present invention: the dual-station clutch assembly includes a connecting plate and transmission ratchet blocks and transmission ratchet rings fixed on both sides of the connecting plate. A sliding frame is rotatably connected to the outer side of the connecting plate. The sliding frame is slidably fitted above the lifting ring seat. The drive pulley is rotatably connected to the output shaft of the motor. The outer side of the motor output shaft is provided with a ratchet groove one that can engage with the transmission ratchet ring. The inner side of the drive pulley is provided with a ratchet groove two that can engage with the outer side of the transmission ratchet ring. The inner wall of the main shaft is provided with a ratchet groove three that can engage with the outer side of the permanent magnet. The transmission ratchet block, transmission ratchet ring, ratchet groove one, ratchet groove two, and ratchet groove three have two working states, which are as follows: The outer side of the transmission ratchet ring engages with the ratchet groove on the inner side of the drive pulley, the inner side of the transmission ratchet ring engages with the ratchet groove on the outer side of the motor output shaft, and the transmission ratchet block does not engage with the ratchet groove on the main shaft. The outer side of the transmission ratchet ring engages with the second ratchet groove on the inner side of the drive pulley, the inner side of the transmission ratchet ring does not engage with the first ratchet groove on the outer side of the motor output shaft, and the transmission ratchet block engages with the third ratchet groove on the main shaft. An electromagnet is fixedly embedded in the inner wall of the lifting ring seat, and a permanent magnet that cooperates with the electromagnet is fixed on the top lower surface of the sliding frame.

[0017] The beneficial effects of this invention are as follows: 1. This invention, by setting up a kneading plate one and a kneading plate two in cooperation, can knead meat when they rotate relative to each other. Furthermore, the kneading plate one also rises and falls while rotating, thereby continuously patting the meat and further increasing the rate at which the marinade penetrates into the meat. At the same time, by setting up a transmission protrusion and a flat key rib in cooperation, the kneading plate one can be raised and lowered by the rotation of the kneading plate one relative to the lifting ring seat, thereby achieving integrated power and reducing the number of power sources required.

[0018] 2. In this invention, by setting the second kneading plate as a movable connection, and cooperating with the transmission head and the transmission groove, the second kneading plate can be driven to rotate when the main shaft rotates. Moreover, the second kneading plate rotates in the opposite direction to the first kneading plate, thereby increasing the relative speed of rotation and kneading, and further increasing the speed at which the marinade penetrates into the meat.

[0019] 3. This invention, by setting heat dissipation holes and a simple one-way valve, utilizes the characteristic of the volume change of the inner cavity of the lifting ring seat during the lifting of the connecting ring to achieve the tapping action. This enables directional exchange of gas between the inner cavity of the lifting ring seat and the outside environment, allowing the heat generated by friction in various components of the inner cavity of the lifting ring seat to be discharged in a timely manner, increasing the stability of the device's operation. At the same time, the heat dissipation process relies on the lifting of the connecting ring itself, eliminating the need for pump components, thereby increasing the synchronicity and linkage of the device.

[0020] 4. The present invention, by setting a dual-station clutch assembly, can use the station switching function to enable the motor to drive the main shaft and the sector flexible pad to rotate at different times, thereby achieving the effect of one-drive-multiple, saving power layout and increasing synchronous linkage.

[0023] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0024] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] Example 1: A tumbling device for meat marinating and processing, such as Figures 1-8 As shown, the device includes a base 1, a container 2 is bolted to the top outer wall of the base 1, a kneading board 10 is provided on the bottom inner wall of the container 2, a gantry frame 3 is bolted to the top outer wall of the base 1, a lifting ring seat 4 is connected to the top of the gantry frame 3 via a lifting mechanism 5, a transmission ring 7 is connected to the inside of the lifting ring seat 4 via a rotation drive mechanism 6, the same connecting ring 8 is connected to the inner side of the lifting ring seat 4 and the outer wall of the transmission ring 7, and a kneading board 9 that mates with the kneading board 10 is fixed to the bottom of the connecting ring 8.

[0026] The outer circumferential wall of the transmission ring 7 is provided with a flat key rib 13, the inner circumferential wall of the connecting ring 8 is provided with a keyway 11 that is clearance-fitted with the flat key rib 13, the inner circumferential wall of the lifting ring seat 4 is provided with a wave-shaped limiting groove 14, and the outer circumferential wall of the connecting ring 8 is fixed with a transmission protrusion 12 that is movable and limited to the wave-shaped limiting groove 14.

[0027] In use, the marinade can be applied or sprinkled on the surface of the meat. The meat is then placed above the second rubbing plate 10. The amount of marinade is then sprinkled on the meat and the second rubbing plate 10 according to the amount needed. The lifting mechanism 5 then lowers the lifting ring seat 4 until the first rubbing plate 9 contacts the meat and there is a certain pressure between the first rubbing plate 9 and the second rubbing plate 10. The lifting mechanism 5 then stops. The rotation drive mechanism 6 drives the transmission ring 7 to rotate. The transmission ring 7 drives the connecting ring 8 to rotate through the cooperation of the wave-shaped limiting groove 14 and the keyway 11, thereby driving the first rubbing plate 9 to rotate and rub the meat. When the connecting ring 8 rotates, the transmission protrusion 12 also rotates relative to the wave-shaped limiting groove 14. The wave-shaped limiting groove 14 limits the transmission protrusion 12, causing the connecting ring 8 to move up and down repeatedly, thereby driving the first rubbing plate 9 to move up and down repeatedly and pat the meat.

[0028] This device, by setting up a kneading plate 9 and a kneading plate 10 in cooperation, can knead the meat when they rotate relative to each other. The kneading plate 9 also rises and falls while rotating, so as to continuously pat the meat and further increase the rate at which the marinade penetrates into the meat. At the same time, by setting up a transmission protrusion 12 and a flat key rib 13 in cooperation, the kneading plate 9 can be raised and lowered by rotating relative to the lifting ring seat 4, thereby realizing power integration and reducing the number of power sources required.

[0029] In order to solve the rotation driving problem; as Figure 3 illustrated, said rotation drive mechanism 6 comprises an electric motor 16, a main shaft 18 and a gear ring 20, said electric motor 16 is fixed above a lifting ring seat 4 through a frame 17, said main shaft 18 is in transmission fit with an output shaft of the electric motor 16 via a double-station clutch assembly 15, a sun gear 23 is key-connected to an outer wall of said main shaft 18, a plurality of planet gears 19 are meshed between opposite sides of the gear ring 20 and the sun gear 23, the planet gears 19 are rotatably connected to an inner wall of the lifting ring seat 4 through rotating shafts, the gear ring 20 is rotatably connected to the inner wall of the lifting ring seat 4, and a bottom of the gear ring 20 is fixedly connected to a top outer wall of a transmission ring 7 through a second connecting ring 21.

[0030] When the electric motor 16 is started, the electric motor 16 can drive the main shaft 18 to rotate, thereby driving the sun gear 23 to rotate, and then driving the gear ring 20 to rotate through the planet gears 19, thereby driving the transmission ring 7 to rotate through the second connecting ring 21.

[0031] In order to further solve the problem of permeation rate; as Figure 4 illustrated, a second kneading plate 10 is rotatably connected to an inner side of a bottom of a containing barrel 2, said main shaft 18 movably penetrates through a first kneading plate 9, a transmission head 24 is welded to a bottom outer wall of the main shaft 18, and a transmission groove matched with the transmission head 24 is formed in an inner wall of the second kneading plate 10.

[0032] In this embodiment, no specific limitation is imposed on the type of the transmission head 24, a cross-section of the transmission head 24 may be in a straight-line shape, a cross shape or a regular polygonal structure. Preferably, said transmission head 24 is of a regular hexagonal prism structure, and correspondingly, the transmission groove is also of a regular hexagonal prism structure.

[0033] In the present device, by arranging the second kneading plate 10 to be movably connected, and matching the cooperation between the transmission head 24 and the transmission groove, the second kneading plate 10 can be driven to rotate when the main shaft 18 rotates, and the rotation direction of the second kneading plate 10 is opposite to that of the first kneading plate 9, thereby increasing the relative motion speed of rotary kneading and further increasing the speed at which the marinade penetrates into the interior of meat.

[0034] In order to solve the heat dissipation problem; as Figure 5 , 6 illustrated, heat dissipation holes 25 are respectively formed in a top inner wall of the lifting ring seat 4 and a bottom side wall of a first connecting ring 8, a simple one-way valve 26 is arranged on an inner wall of each heat dissipation hole 25, a passage direction of the simple one-way valve 26 in the lifting ring seat 4 is from an interior of the lifting ring seat 4 to an exterior of the lifting ring seat 4, and a passage direction of the simple one-way valve 26 in the first connecting ring 8 is from an exterior of the first connecting ring 8 to an interior of the first connecting ring 8.

[0035] The simple one-way valve 26 includes a perforated plate 27 fixed to the inner wall of the heat dissipation hole 25 and a plurality of fan-shaped flexible pads 28 fixed to the inner wall of the heat dissipation hole 25. The plurality of fan-shaped flexible pads 28 are arranged in a circular array and can form a complete circular plane. The perforated plate 27 and the fan-shaped flexible pads 28 are in contact with each other.

[0036] Furthermore, both the transmission ring 7 and the connecting ring 21 have uniform through holes 22 on their side walls.

[0037] As the connecting ring 8 moves up and down relative to the lifting ring seat 4, the volume of the inner cavity of the lifting ring seat 4 changes. When the connecting ring 8 rises relative to the lifting ring seat 4, the volume of the inner cavity of the lifting ring seat 4 decreases and the air pressure in the inner cavity increases. This causes the fan-shaped flexible pad 28 inside the lifting ring seat 4 to deform under the air pressure and expel the gas. When the connecting ring 8 falls relative to the lifting ring seat 4, the volume of the inner cavity of the lifting ring seat 4 increases and the air pressure in the inner cavity decreases. As a result, the external atmospheric pressure squeezes and deforms the fan-shaped flexible pad 28 inside the connecting ring 8, and the gas enters the inner wall of the lifting ring seat 4.

[0038] This device, by setting heat dissipation holes 25 and a simple one-way valve 26, utilizes the characteristic of the volume change of the inner cavity of the lifting ring seat 4 when the connecting ring 8 is raised and lowered to achieve the tapping action. This allows for directional exchange of gas between the inner cavity of the lifting ring seat 4 and the outside environment, thus enabling the heat generated by friction in various components of the inner cavity of the lifting ring seat 4 to be discharged in a timely manner, increasing the stability of the device's operation. At the same time, the heat dissipation process is achieved by the raising and lowering of the connecting ring 8 itself, eliminating the need for pump components, thereby increasing the synchronicity and linkage of the device.

[0039] To solve the lifting control problem; such as Figure 7 As shown, the lifting mechanism 5 includes a driving pulley 29, two driven pulleys 31, and two lead screws 32. The lead screws 32 are rotatably connected to the top of the lifting ring seat 4 and are threaded to the inner wall of the gantry frame 3. The driven pulleys 31 are keyed to the outer wall of the lead screws 32. The driving pulley 29 is driven and engaged with the outer wall of the output shaft of the motor 16 through a dual-position clutch assembly 15. The driving pulley 29 and the driven pulleys 31 are driven and engaged with the same synchronous belt 30 on their outer walls.

[0040] When the motor 16 starts, it drives the drive pulley 29 to rotate through the dual-position clutch assembly 15, which in turn drives the driven pulley 31 to rotate through the synchronous belt 30, causing the lead screw 32 to rotate. Then, through the threaded connection between the lead screw 32 and the gantry 3, the lifting ring seat 4 is lifted and lowered.

[0041] In this embodiment, the marinade can be applied or sprinkled on the surface of the meat. The meat is then placed above the second rubbing plate 10. The amount of marinade is then sprinkled over the meat and the second rubbing plate 10 according to the desired amount. When the motor 16 starts, it drives the drive pulley 29 to rotate via the dual-position clutch assembly 15. This, in turn, drives the driven pulley 31 to rotate via the synchronous belt 30, causing the lead screw 32 to rotate. The threaded connection between the lead screw 32 and the gantry 3 lowers the lifting ring seat 4 until the first rubbing plate 9 contacts the meat and applies pressure between the first rubbing plate 9 and the second rubbing plate 10. At this point, the lifting mechanism 5 stops. Then, the rotation drive mechanism 6 drives the transmission ring 7 to rotate. The transmission ring 7, through the engagement of the wave-shaped limiting groove 14 and the keyway 11, drives the connecting ring 8 to rotate, thereby rotating the first rubbing plate 9 and achieving the desired pressure on the meat. The kneading and rubbing of the meat, along with the rotation of the connecting ring 8, causes the transmission protrusion 12 to rotate relative to the wave-shaped limiting groove 14. This limiting groove 14 restricts the transmission protrusion 12, causing the connecting ring 8 to move up and down repeatedly, which in turn drives the kneading plate 9 to move up and down repeatedly, patting the meat. As the connecting ring 8 moves up and down relative to the lifting ring seat 4, the volume of the inner cavity of the lifting ring seat 4 changes. When the connecting ring 8 rises relative to the lifting ring seat 4, the volume of the inner cavity of the lifting ring seat 4 decreases, and the air pressure in the inner cavity increases. This causes the fan-shaped flexible pad 28 inside the lifting ring seat 4 to deform under the air pressure, expelling the gas. When the connecting ring 8 falls relative to the lifting ring seat 4, the volume of the inner cavity of the lifting ring seat 4 increases, and the air pressure in the inner cavity decreases. This causes the external atmospheric pressure to squeeze and deform the fan-shaped flexible pad 28 inside the connecting ring 8, allowing gas to enter the inner wall of the lifting ring seat 4.

[0042] Example 2: To solve the linkage problem, this example makes the following improvements based on Example 1: The dual-station clutch assembly 15 includes a connecting plate 37 and transmission ratchet blocks 34 and transmission ratchet rings 38 fixed on both sides of the connecting plate 37. A sliding frame 33 is rotatably connected to the outer side of the connecting plate 37. The sliding frame 33 is slidably fitted above the lifting ring seat 4. The drive pulley 29 is rotatably connected to the output shaft of the motor 16. The outer side of the output shaft of the motor 16 is provided with a ratchet groove 1 that can engage with the transmission ratchet ring 38. The inner side of the drive pulley 29 is provided with a ratchet groove 2 that can engage with the outer side of the transmission ratchet ring 38. The inner wall of the main shaft 18 is provided with a ratchet groove 3 that can engage with the outer side of the permanent magnet 36.

[0043] The transmission ratchet block 34, transmission ratchet ring 38, ratchet groove one, ratchet groove two, and ratchet groove three have two working states, which are as follows: The outer side of the transmission ratchet ring 38 engages with the ratchet groove on the inner side of the drive pulley 29, the inner side of the transmission ratchet ring 38 engages with the ratchet groove on the outer side of the output shaft of the motor 16, and the transmission ratchet block 34 does not engage with the ratchet groove on the main shaft 18. The outer side of the transmission ratchet ring 38 engages with the ratchet groove 2 on the inner side of the drive pulley 29, the inner side of the transmission ratchet ring 38 does not engage with the ratchet groove 1 on the outer side of the output shaft of the motor 16, and the transmission ratchet block 34 engages with the ratchet groove 3 on the main shaft 18.

[0044] An electromagnet 35 is fixedly embedded in the inner wall of the lifting ring seat 4, and a permanent magnet 36 that cooperates with the electromagnet 35 is fixed on the top lower surface of the sliding frame 33.

[0045] In this embodiment, when the electromagnet 35 is energized, it generates an attractive force with the permanent magnet 36, causing the sliding frame 33 to descend under the attraction. At this time, the outer side of the transmission ratchet 38 engages with the second ratchet groove on the inner side of the drive pulley 29, while the inner side of the transmission ratchet 38 does not engage with the first ratchet groove on the outer side of the output shaft of the motor 16. The transmission ratchet block 34 engages with the third ratchet groove on the main shaft 18. The motor 16 can start and drive the main shaft 18 to rotate. When a reverse current is applied to the electromagnet 35, it generates a repulsive force with the permanent magnet 36. At this time, the outer side of the transmission ratchet 38 engages with the second ratchet groove on the inner side of the drive pulley 29, while the inner side of the transmission ratchet 38 engages with the first ratchet groove on the outer side of the output shaft of the motor 16. The transmission ratchet block 34 does not engage with the third ratchet groove on the main shaft 18. The motor 16 can start and drive the drive pulley 29 to rotate.

[0046] This device, by setting a dual-station clutch assembly 15, can use the station switching function to allow the motor 16 to drive the main shaft 18 and the sector flexible pad 28 to rotate at different times, thereby achieving the effect of one-drive-multiple, saving power layout and increasing synchronous linkage.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
