Description

Technical Field

[0001] This utility model relates to the field of meat processing technology, specifically to a rapid deboning device for meat processing. Background Technology

[0002] In the modern meat processing industry, the demand for deep processing of poultry products continues to grow. Take chicken legs as an example; as a popular ingredient, they are often used to make various forms such as steaks, skewers, and ready-to-eat seasoned products.

[0003] According to CN220068707U, a chicken leg deboning device is disclosed. This technology discloses a technical solution including "a base, a feeding pool fixedly installed on the upper part of the base by a column, a feeding hole at the bottom of the feeding pool, a slide rail fixedly installed on the bottom of the feeding pool radially from the feeding hole, a slider slidably mounted on the slide rail, and an arc-shaped deboning knife on the slider". It has the technical effect of "clamping the lower joint of the chicken leg bone with a bone joint clamping device, and performing the deboning process by the elastically sliding arc-shaped deboning knife. The deboning process of chicken leg meat is completed in the process of pulling down the chicken leg bone, which solves the problem of complex and inefficient manual deboning of chicken leg bones in the prior art".

[0004] In the above method, the operator needs to manually pull down the chicken leg bone. During this process, the curved boning knife, which relies on spring pressure, will continuously slide and scrape against the surface of the leg bone. This friction-dependent cutting method will remove a large number of fine bone fragments from the bone and embed them directly into and contaminate the surrounding meat tissue. Utility Model Content

[0010] Preferably, the driving component includes a guide rail seat fixed to the middle of the lower end of the base plate, and slide brackets are slidably installed on both the front and rear sides of the lower end of the guide rail seat. A mounting seat is fixed to the left side of the lower end of the base plate, and a dual-axis cylinder is installed at the bottom of the mounting seat. A connecting seat is fixed to the right output end of the dual-axis cylinder. Two support rods are pivotally connected to the connecting seat, and the other end of the support rods is pivotally connected to the bottom of the slide bracket.

[0011] Preferably, the lifting assembly further includes side frames fixed to the left and right ends of the bottom of the base plate, a guide frame fixed to the outer end of the side frame, a lifting rod slidably installed longitudinally inside the guide frame, and a standard cylinder installed at the bottom of the guide frame for driving the lifting rod to rise and fall.

[0012] Preferably, the clamping assembly further includes a housing fixed to the upper end of the lifting rod. A shaft seat is fixed to the upper end of the housing. A shaft frame is slidably mounted longitudinally through the shaft seat. A cylinder is installed inside the housing for driving the shaft frame to lift.

[0015] Beneficial effects

[0016] This invention provides a rapid deboning device for meat processing. Compared with the prior art, it has the following advantages:

[0017] 1. When the drive component pushes the support rod to move laterally, it will drive the rotating rods at both ends of the rod to move, thereby forcing the first and second connecting rods, which are respectively hinged to the ends of the rotating rods, to move together. Since the other end of the first connecting rod is hinged to the top of the fixed base, and the other end of the second connecting rod is hinged to the crossbeam, this motion constraint converts the displacement of the support rod into the opposite movement of the front and rear crossbeams on the horizontal plane. When the front and rear crossbeams move towards each other, the two annular picks fixed on them will simultaneously close from both sides of the chicken leg bone to form a complete annular cut, cutting off the muscles and tendons connecting the bottom of the chicken leg to the bone, so that the meat and bone are separated at the top.

[0018] 2. Before the ring-shaped cutter closes and makes the cut, the lifting assembly first activates. The output end of the standard cylinder extends, driving the lifting rod to slide upward along the guide frame, thereby raising the clamping assembly located at its top, allowing it to smoothly approach and clamp the lower end of the chicken leg bone from below. After the clamping assembly firmly clamps the bone and the ring-shaped cutter completes the ring cut, the output end of the standard cylinder retracts, driving the lifting rod, along with the clamping assembly and the chicken leg bone it clamps, to move downward together, thereby removing the bone from the chicken leg meat that has already been ring-cut above.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a rapid deboning device for meat processing, including a base plate 1, on which a deboning mechanism 2 is disposed and used for deboning processing, the deboning mechanism 2 including:

[0027] The main component 21 includes a fixing seat 211 fixed on the left and right sides of the front and rear ends of the substrate 1. A support rod 212 is provided between the two fixing seats 211. A rotating rod 213 is rotatably installed on both the left and right ends of the support rod 212. A first connecting rod 214 and a second connecting rod 215 are pivotally connected to both ends of the rotating rod 213. The end of the first connecting rod 214 away from the support rod 212 is pivotally connected to the top of the fixing seat 211. A cross frame 216 is provided on both the front and rear sides of the substrate 1. The end of the second connecting rod 215 away from the rotating rod 213 is pivotally connected to the top of the cross frame 216. A ring-shaped chisel 3 is fixed on the inner wall of both the left and right ends of the cross frame 216. A driving component 217 is provided on the substrate 1 and is used to drive the support rod 212 to move laterally.

[0028] Clamping components 22 are disposed on the left and right sides of the substrate 1 and are used to clamp chicken leg bones;

[0029] The lifting assembly 23 is disposed at both ends of the base plate 1 and is used to drive the clamping assembly 22 to lift.

[0030] In this embodiment, when the drive component 217 pushes the support rod 212 to move laterally, it will drive the rotating rods 213 at both ends of the rod to move, thereby forcing the first connecting rod 214 and the second connecting rod 215, which are respectively hinged to the two ends of the rotating rod 213, to move together. Since the other end of the first connecting rod 214 is hinged to the top of the fixed base 211, and the other end of the second connecting rod 215 is hinged to the cross frame 216, this motion constraint converts the displacement of the support rod 212 into the opposite movement of the front and rear cross frames 216 on the horizontal plane. When the front and rear cross frames 216 move towards each other, the two annular picks 3 fixed on them will simultaneously close from both sides of the chicken leg bone to form a complete annular cut, cutting off the muscles and tendons connecting the bottom of the chicken leg to the bone, so that the meat and bone are separated at the upper end.

[0031] Specifically, the drive component 217 includes a guide rail seat 2171 fixed in the middle of the lower end of the substrate 1. A slide 2172 is slidably mounted on both the front and rear sides of the lower end of the guide rail seat 2171. A mounting seat 2173 is fixed on the left side of the lower end of the substrate 1. A dual-axis cylinder 2174 is mounted on the bottom of the mounting seat 2173. A connecting seat 2175 is fixed on the right output end of the dual-axis cylinder 2174. Two support rods 2176 are pivotally connected to the connecting seat 2175, and the other end of the support rods 2176 is pivotally connected to the bottom of the slide 2172.

[0032] In this embodiment, when the right output end of the dual-axis cylinder 2174 extends, it will push the connecting seat 2175 to move to the right, and the two support rods 2176 pivotally connected to the connecting seat 2175 will move accordingly. Since the other end of the support rod 2176 is pivotally connected to the bottom of the front and rear slides 2172 respectively, and the slides 2172 are constrained on the guide rail seat 2171 and can only slide laterally, the straight forward movement of the connecting seat 2175 will force the two support rods 2176 to drive the two front and rear slides 2172 to close inward synchronously.

[0033] Specifically, the lifting assembly 23 also includes side frames 231 fixed to the left and right ends of the bottom of the base plate 1. A guide frame 232 is fixed to the outer end of the side frame 231. A lifting rod 233 is longitudinally slidably installed inside the guide frame 232. A standard cylinder 234 is installed at the bottom of the guide frame 232 and is used to drive the lifting rod 233 to lift.

[0034] In this embodiment, before the annular scraper 3 closes to cut, the lifting component 23 first activates, the output end of the standard cylinder 234 extends, and drives the lifting rod 233 to slide upward along the guide frame 232, thereby raising the clamping component 22 located at its top, so that it can smoothly approach and clamp the lower end of the chicken leg bone from below; after the clamping component 22 firmly clamps the bone and the annular scraper 3 completes the annular cut, the output end of the standard cylinder 234 retracts, and drives the lifting rod 233, together with the clamping component 22 and the chicken leg bone clamped by it, to move downward, thereby removing the bone from the annularly cut chicken leg meat above.

[0035] Specifically, the clamping assembly 22 also includes a housing 221 fixed to the upper end of the lifting rod 233. A shaft seat 222 is fixed to the upper end of the housing 221. A shaft bracket 223 is longitudinally slidably installed inside the shaft seat 222. A cylinder is installed inside the housing 221 to drive the shaft bracket 223 to lift. Four main clamping arms 224 arranged in a circle are pivotally connected to the shaft seat 222. A chuck 225 is pivotally connected to the upper end of the main clamping arm 224. Four connecting arms 226 arranged in a circle are pivotally connected to the shaft bracket 223. The upper end of the connecting arm 226 is pivotally connected to the middle of the main clamping arm 224. Four secondary clamping arms 227 are pivotally connected to the shaft seat 222. The upper end of the secondary clamping arm 227 is pivotally connected to the lower end of the chuck 225. The secondary clamping arm 227 is arranged parallel to the main clamping arm 224.

[0036] In this embodiment, when the cylinder inside the housing 221 pushes the shaft frame 223 downward, the shaft frame 223 drives its four circumferentially distributed connecting arms 226 to descend together. The upper end of the connecting arm 226 is hinged to the middle of the main clamping arm 224, thereby forcing the main clamping arm 224 to rotate inward with its hinge point with the shaft seat 222 as the fulcrum. At the same time, the clamp 225, which is hinged to the upper end of the main clamping arm 224, and the secondary clamping arm 227, which is also hinged to the shaft seat 222 and arranged parallel to the main clamping arm 224, together form a parallel four-bar linkage structure. This structure ensures that the clamp 225 always maintains the preset posture for radial translation rather than rotation during the entire movement. This allows the clamping assembly 22 to evenly surround and clamp the irregularly shaped chicken leg bone from all sides. By clamping evenly, stress concentration is avoided, which could crush the fragile bone.

[0037] Specifically, the main component 21 also includes a guide seat 218 fixed to the top of the fixed base 211. A guide rod 219 is slidably installed through the guide seat 218, and the guide rod 219 is fixed to the cross frame 216.

[0038] In this embodiment, when the crossbeam 216 moves, the guide rod 219 slides laterally under the constraint of the guide seat 218, thereby enhancing the stability and accuracy of the crossbeam 216 in the horizontal direction.

[0039] Specifically, the first link 214 and the second link 215 are of equal length and are parallel to each other, located on the same side.

[0040] In this embodiment, since the first link 214 and the second link 215 are of equal length and parallel to each other on the same side, the quadrilateral formed by the hinge point of the fixed seat 211, the first link 214, a section of the rotating rod 213, and the virtual connecting line remains a parallelogram during movement. This geometric constraint directly determines that the crossbar 216, which is hinged to the end of the second link 215, will undergo strict translational movement during movement, rather than swinging or a combination of movements.

[0041] The working principle and usage process of this utility model are as follows: At the start of operation, the lifting assembly 23 is activated, with its standard cylinder 234 pushing the lifting rod 233 upwards along the guide frame 232, causing the clamping assembly 22 at the top to move upwards, so that the clamps 225 reach the predetermined position at the lower end of the chicken leg bone. Next, the cylinder inside the housing 221 drives the shaft frame 223 downwards, pulling the parallel four-bar linkage mechanism composed of the main clamping arm 224 and the auxiliary clamping arm 227 via the connecting arm 226, causing the four clamps 225 to synchronously and radially retract, evenly clamping the chicken leg bone from all sides. Subsequently, the deboning mechanism 2 begins operation: the dual-axis cylinder 2174 pushes the connecting seat 2175 to move, and the support rod 2176 pushes the two slides 2172 onto the guide rail seat 2171. The upper part moves inward synchronously, thereby driving the support rod 212 to move laterally; the support rod 212 drives the rotating rod 213 to move, causing the parallel double crank mechanism formed by the first connecting rod 214 and the second connecting rod 215 to be linked, and finally the motion is transmitted to the front and rear crossbars 216. Under the precise guidance of the guide rod 219 and the guide seat 218, the two crossbars 216 move steadily in opposite directions with the annular deboning knife 3, closing from both sides to complete the annular cut and completely separating the tendons and meat connected to the upper end of the chicken leg bone; finally, the lifting assembly 23 is activated again, the standard cylinder 234 pulls the lifting rod 233 down, and the clamping assembly 22 vertically pulls the completely cut and separated chicken leg bone out of the meat, thus completing the entire deboning process.
