Description

Technical Field

[0001] This utility model relates to the field of suspended pig carcass splitting, and in particular to an automatic disc splitting machine. Background Technology

[0002] In the meat processing industry, splitting and cutting pigs after slaughter is a key process for achieving refined processing of pigs and improving the efficiency of subsequent product production. Its core requirements are to ensure the accuracy, stability and safety of the splitting process, while taking into account the ease of operation of the equipment and its adaptability to pigs of different sizes.

[0003] Currently, mainstream pig splitting equipment on the market still suffers from several technical defects. Firstly, the feeding and positioning structure design is unreasonable. Most machines only use a single-direction feeding plate to fix the pig's body, without an adaptive positioning mechanism designed for the pig's back contour and vertebral position. This causes the pig to easily shift during cutting, making it impossible to ensure the blade always cuts along the midline of the spine, resulting in a splitting qualification rate of only around 80%. Secondly, there is a lack of targeted auxiliary components for adjusting the pig's tail, making the tail easily cut by the blade, causing product loss. Furthermore, existing splitting equipment has poor adaptability, unable to flexibly adjust positioning according to differences in pig body shape, resulting in compression deformation or cutting deviation.

[0004] For example, patent document CN201320600318.4, entitled "Automatic Suspended Pig Carcass Splitting Machine," discloses an automatic splitting machine processing equipment that continuously and automatically splits pig carcasses conveyed by a conveyor into two-piece meat slices online. It consists of a translation device equipped with a lifter, a longitudinal transducer, a splitting blade, and a clamping device. The splitting blade is equipped with a splitting blade housing, a frequency converter, a reducer, an eccentric shaft, left and right blade rods, left and right blades, and a pressure plate. The clamping device is equipped with a guide beam, a pressure arm, a left arm, a left side plate, a right arm, a right side plate, a cylinder, a pressure roller shaft, a pressure roller, and a torsion spring. A lubrication device is located at the front end of the splitting blade. The controller is connected to a computer to control the translation device, lifter, longitudinal transducer, splitting blade, clamping device, disinfection and cleaning device, lubrication device, and safety protector. The advantages are simple structure, convenient operation, automated operation, high production efficiency, time and labor saving, reduced meat loss, no cross-contamination, and wide application in continuous automated pig carcass splitting processing equipment.

[0005] The automated suspended pig carcass splitting machine described in the aforementioned patent document uses a double-blade splitting method, resulting in an uneven cut surface, material waste, and asymmetry between the left and right halves. The clamping device used lacks an extension function; it can only achieve horizontal clamping by allowing the clamping wheels to rotate around an axis.

[0006] This utility model aims to address the shortcomings of the existing technology by providing an automatic disc splitting machine. It solves the problem of inaccurate positioning leading to cutting deviation through a back pressing mechanism and a pushing mechanism. The disc blade makes the cutting surface flat, and the pig tail is pushed to both sides before the blade enters the machine to avoid accidental cutting, thus preserving the whole product and reducing pork loss.

[0012] Furthermore: One end of the back pressure wheel bracket is rotatably connected to two back pressure wheels with larger diameters, and the other end of the back pressure wheel bracket is provided with a V-shaped connecting ear, which connects to two back pressure wheels with smaller diameters respectively. The back pressure wheel assembly is H-shaped. The back pressure wheel assembly has a shaft hole in the center that mates with the wheel axle, allowing it to rotate around the shaft. The back pressure wheel has a fan-shaped spoke structure, with radial fan-shaped protrusions distributed on the wheel rim. The wheel body edges of the two sets of back pressure wheels are inclined towards the side that is close to each other, forming a trapezoidal groove in the middle, which can be used to lock and fix the pig keel.

[0013] Furthermore: The cylinder body end of the front and rear cylinder assemblies is fixed to the frame by a mounting base, and its piston rod end is rigidly connected to the slide plate. The slide plate is slidably engaged with the frame by a linear guide rail. The other end of the slide plate is fixedly connected to a push arm, and its lower part is hinged to the cylinder body of the positioning and guiding cylinder assembly. The positioning and guiding cylinder assembly is in a continuously inflated state to provide a rebound force through its internal air pressure.

[0014] Furthermore: the positioning guide wheel bracket has two triangular bracket pieces arranged in parallel, connected by the positioning guide wheel shaft to form a central cavity; the positioning guide wheel bracket has arc-shaped elongated holes on both sides, and the end of the push arm passes through the arc-shaped elongated hole through a pin, which can slide along the arc path of the arc-shaped elongated hole, thereby hinged to the positioning guide wheel bracket; the cylinder rotation output shaft of the positioning guide cylinder group acts on the rotation action hole at the lower part of the positioning guide wheel bracket; at the same time, the end of the push arm is provided with a push arm rotation shaft, which passes through the push arm rotation hole in the middle of the positioning guide wheel bracket, serving as the axis for driving the positioning guide wheel bracket to reciprocate along the arc-shaped elongated hole; the positioning guide wheel adopts a multi-wheel combination structure and is distributed in an H-shape in the central cavity, with two positioning guide wheels with smaller wheel diameters at the upper part of the positioning guide wheel bracket and two positioning guide wheels with larger wheel diameters at the lower part, and the horizontal spacing of the positioning guide wheels is adapted to the width of the pig keel.

[0018] The beneficial effects of this utility model are as follows:

[0019] This invention utilizes a coordinated positioning design of a pushing mechanism and a back-pressing mechanism. The positioning guide wheel of the pushing mechanism (with a groove adapted to the pig's spine) precisely engages with the spine, while the V-shaped back-pressing wheel of the back-pressing mechanism secures the body from the back. This dual positioning ensures that the disc blade is always aligned with the midline of the spine during cutting, effectively avoiding the cutting deviation problem caused by positioning errors in traditional equipment. This significantly improves the symmetry and pass rate of splitting, reduces meat damage and raw material waste, and meets the standardization requirements of meat processing. The front and rear cylinder groups of the pushing mechanism drive the pushing arm to move back and forth, while the positioning guide cylinder group is continuously inflated, adaptively adjusting the angle and pressure of the positioning guide wheel. The back-pressing cylinder of the back-pressing mechanism can flexibly control the downward pressure of the back-pressing wheel, achieving positioning for pigs of different weights. Furthermore, this invention is equipped with a pig tail-pulling component, a rinsing and cooling component, and a knife-protecting component, providing comprehensive processing protection.

Detailed Implementation

[0028] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. This embodiment provides specific and implementable technical details for the above-mentioned inventive solution, to solve the problems of uneven cutting surfaces, inaccurate positioning leading to cutting deviation, and damage to the integrity of the pig's tail during the cutting process in existing pig splitting equipment, while also being adaptable to pigs of various body sizes.

[0029] Please see Figures 1 to 7 As shown, this utility model discloses an automatic disc splitting machine, which includes a frame 1, a drive mechanism 2, a back pressing mechanism 3, a pushing mechanism 4, and a cutting mechanism 5. In order to solve the problems of uneven cutting surface, inaccurate positioning leading to cutting deviation, and damage to the integrity of pig tails during the cutting process in existing pig splitting equipment, and to adapt to pigs of various body sizes, it is necessary to optimize the structure of the back pressing mechanism 3, the pushing mechanism 4, and the cutting mechanism 5 to meet production needs.

[0030] The automatic disc splitting machine is based on the frame 1. The frame 1 is made of high-strength steel and welded together. The left end is equipped with a back pressing mechanism 3, the middle part is equipped with a working platform corresponding to the cutting mechanism 5, the right end has a cavity for installing the drive mechanism 2, and the lower part is equipped with a push mechanism 4.

[0031] To position the pig's back keel and guide the cutting mechanism 5, a back-pressing mechanism mounting base 305 is installed at the left end of the frame 1. This mounting base is made of high-strength cast steel and has multiple hinge holes and mounting surfaces on its surface, providing reliable mounting support for the back-pressing cylinder 301 and the back-pressing arm 302. The cylinder body of the back-pressing cylinder is hinged to the back-pressing mechanism mounting base via a hinge pin, ensuring that the cylinder can swing flexibly around the pin. The back-pressing arm has an overall L-shaped structure. Its upper part is rotatably connected to the back-pressing mechanism mounting base via a rotating shaft, and its lower part is hinged to the piston rod end of the back-pressing cylinder, ensuring that the back-pressing cylinder can drive the back-pressing arm 302 to rotate around the shaft. The hollow design on the back-pressing arm is to reduce weight and improve the mobility or energy efficiency of the equipment while ensuring transmission strength.

[0032] A rotating shaft 306 is installed at the end of the back pressure arm. The inverted V-shaped back pressure wheel bracket 303 has a bracket mounting hole 308 that is adapted to the rotating shaft. The rotating shaft passes through the bracket mounting hole, so that the back pressure wheel bracket can rotate around the rotating shaft.

[0033] Furthermore, in order to prevent the back pressure roller bracket 303 from axially moving on the rotating shaft 306, the rotating shaft 306 is also provided with a number of limiting rings 307 to restrict its axial displacement. These limiting rings securely limit the back pressure roller bracket 303 on the rotating shaft 306.

[0034] Furthermore, to ensure the pig is centered, an integrally formed inverted V-shaped back-pressing wheel bracket 303 is rotatably connected to the end of the back-pressing arm 302 via a rotating shaft 306. The back-pressing arm is equipped with a bearing seat to support the rotating shaft 306. The back-pressing wheel assembly 304 includes two sets of back-pressing wheels with different diameters. One end of the back-pressing wheel bracket is rotatably connected to two larger-diameter back-pressing wheels via an axle, while the other end has a V-shaped connecting ear 309. Two smaller-diameter back-pressing wheels are connected to the two branches of this V-shaped connecting ear 309 via axles. The back-pressing wheels have a fan-shaped spoke structure with radial fan-shaped protrusions distributed on their rims. This structure helps to enhance friction and bite force with the bone surface.

[0035] Furthermore, to ensure structural stability when pressing down on the pig's back, the upper pressing roller has a smaller diameter while the lower pressing roller has a larger diameter. The larger roller at the bottom conforms to the bottom contour of the spine, forming a stable support track; the smaller roller at the top adapts to the narrow upper surface of the spine, guiding the spine along a preset path during pressing or splitting, preventing material deviation and improving processing accuracy. The 304 stainless steel roller body of the pressing roller assembly is covered with a wear-resistant rubber layer, and the surface of the rubber layer has a diamond-shaped anti-slip texture, which ensures stable pressing of the pig's back while avoiding damage to the pig's back skin.

[0036] Furthermore, to enhance the centering positioning, the back-pressing rollers are conical rollers, with the edges of the two sets of back-pressing rollers inclined toward each other, forming a trapezoidal clamping channel in the middle. Utilizing the lateral constraint force when the symmetrical inclined surface contacts the pig's back surface, the positional deviation of the whole pig is automatically corrected. Regardless of slight differences in the pig's size or minor deviations during transport, the inclined surface of the trapezoidal structure can guide it to the cutting centerline, avoiding problems such as off-center cutting or missed cutting.

[0037] The back-pressing cylinder 301 is connected to the pneumatic control system. Initially, the back-pressing cylinder is in a retracted state, and the back-pressing arm is in a raised state. When the whole pig is transported to the designated position, the pneumatic control system supplies air to the back-pressing cylinder, causing the cylinder piston rod to extend and push the back-pressing arm to rotate downwards around the center of rotation. When it presses onto the pig's back, the back-pressing wheel bracket at the end of the back-pressing arm drives the four back-pressing wheels to move synchronously. The two sets of V-shaped back-pressing wheels precisely press onto the middle of the pig's back, and the V-shaped structure of the wheel body fits the contour of the pig's back, forming a cutting guide trajectory. After the halving is completed, the pneumatic control system controls the back-pressing cylinder to exhaust air, the piston rod retracts, and pulls the back-pressing arm upwards around the center of rotation to reset. The back-pressing wheels leave the pig's back, ready for the next work cycle.

[0038] Furthermore, in order to position the inner surface of the pig's keel, a pushing mechanism 4 is fixedly installed on the frame 1 below the drive mechanism 2. The pushing mechanism 4 works in conjunction with the back pressing mechanism 3 to position the whole pig and ensure that the disc cutter 501 is aligned with the midline of the pig's vertebrae during cutting.

[0039] Furthermore, in order for the pushing mechanism 4 to clamp the pig keel in the horizontal direction, a front and rear cylinder assembly 401 is fixed to one side of the pushing mechanism 4 via a mounting base. The top of its output end is welded to the slide plate 402. The slide plate is connected to the frame 1 by a sliding guide rail to ensure smooth forward and backward movement.

[0040] Furthermore, in order for the pushing mechanism 4 to clamp the pig keel in the vertical direction, the lower part of the other end of the slide plate 402 is fixedly connected to the pushing arm 403 by bolts. The lower part of the pushing arm 403 is hinged to the cylinder body of the positioning guide cylinder group 404 by a hinge shaft. The end of the pushing arm is provided with a pin 408, which passes through the arc-shaped long hole 407 of the positioning guide wheel bracket 406. The pin and the arc-shaped long hole are clearance fit, so the positioning guide wheel bracket 406 can slide freely along the arc path of the arc-shaped long hole 407. The end of the pushing arm is also provided with a pushing arm rotation shaft 409, which serves as the rotation center of the positioning guide wheel bracket 406. The pushing arm rotation shaft 409 is sleeved in the pushing arm rotation hole 411.

[0041] The positioning guide wheel bracket 406 is composed of two triangular bracket pieces arranged in parallel, forming a central cavity between them to accommodate the positioning guide wheel and related connecting parts such as wheel axles.

[0042] The positioning guide wheel 405 adopts a multi-wheel combination structure, including at least two sets of wheels. In this embodiment, there are two sets, one upper and one lower. These wheels are distributed vertically within the cavity between two parallel triangular support plates. The upper wheel has a smaller diameter, while the lower wheel has a larger diameter. This arrangement helps to better support and guide bones of different diameters or irregular shapes.

[0043] Each set of wheels has its axle connected at both ends to corresponding mounting positions on two triangular support plates, forming a clamp-like installation structure that ensures the stability of the wheel installation and the flexibility of rotation. The horizontal spacing between the two sets of positioning guide wheels 405 can be adapted to the width of the pig's spine, ensuring that it fits the surface of the spine during positioning.

[0044] Furthermore, to ensure smooth sliding, each positioning guide wheel is disc-shaped with a smooth rim to reduce damage to the bone surface and ensure smooth delivery.

[0045] Furthermore, in order to convert the linear thrust of the positioning guide cylinder assembly 404 into rotational torque, so that it drives the positioning guide wheel bracket 406 to rotate around the axis for a limited position, a cylinder rotation output shaft 410 is provided at the end of the piston cylinder of the positioning guide cylinder assembly 404, and the cylinder rotation output shaft 410 passes through the rotation action hole 412 on the bracket.

[0046] Furthermore, to accommodate individual differences in the thickness of the pig's spine and the contour of its back, the positioning guide cylinder assembly 404 is continuously inflated. Under continuous inflation, the internal air pressure of the cylinder creates a stable elastic rebound force, ensuring that even if the pig's inner surface is uneven, the positioning guide wheel remains in contact with the keel on the pig's inner surface. This flexible positioning also adapts to pigs of different sizes, ensuring that the spine of each pig is precisely aligned with the cutting centerline, avoiding misalignment.

[0047] The working process of the pushing mechanism 4 is as follows: In the initial state, the front and rear cylinder groups 401 are in a retracted state, and the slide plate 402 is located in the initial position of the linear guide rail. When the whole pig is transported to the position, the front and rear cylinder groups 401 are inflated, the piston rod extends and pushes the slide plate 402 to slide forward along the linear guide rail, and the positioning guide wheel 405 gradually approaches the vertebrae on the inside of the pig. After the positioning guide wheel contacts the pig's vertebrae, it fits tightly against the surface of the vertebrae under the rebound force of the positioning guide cylinder group 404; at the same time, the positioning guide wheel bracket 406 slides and rotates along the arc path through the cooperation of the arc-shaped elongated hole 407 and the pin 408, adaptively adjusting the angle to completely fit the contour of the vertebrae in different postures. During the splitting and cutting process, the positioning guide cylinder group 404 is continuously inflated, and the rebound force of the internal air pressure keeps the positioning guide wheel close to the vertebrae, offsetting the displacement risk caused by cutting vibration; the front and rear cylinder groups remain in the extended state, maintaining the forward positioning posture of the pushing arm 403. After cutting, the front and rear cylinder assemblies exhaust air, the piston rod retracts and pulls the slide plate backward, the push arm drives the positioning guide wheel away from the pig body, and the positioning guide cylinder assembly remains in an inflated state, waiting for the next operation cycle.

[0048] Meanwhile, the 501 disc cutter generates continuous vibration during high-speed rotation, especially when cutting bones, where the vibration amplitude increases. The continuously inflated positioning guide cylinder assembly also acts as a buffer. When the vibration causes the guide wheel to be subjected to additional pressure, the air pressure absorbs the impact force through slight compression, avoiding rigid friction or impact between the guide wheel and the spine or equipment components. This reduces wear on vulnerable parts such as bearings and push arms, extends equipment life, protects meat integrity, and reduces the defect rate.

[0049] The cutting mechanism 5 is the core execution unit for achieving the splitting operation, and includes a cutting arm, a disc cutter 501, and auxiliary components.

[0050] Furthermore, in order to withstand the force generated during cutting, the cutting arm is the main load-bearing component. The cutting arm is made of high-strength aluminum alloy in one piece and is fixed to the middle of the frame 1 by bolts. The middle section of the cutting arm is provided with a bearing seat 502. The drive shaft 503 passes through the bearing seat and is connected to the disc cutter 501. The disc cutter 501 is fastened to the drive shaft by a lock nut to ensure that there is no loosening during rotation.

[0051] Furthermore, to ensure a smooth cutting surface, the disc cutter 501 is made of high-strength alloy steel, and the blade is equipped with a serrated structure to enhance cutting sharpness.

[0052] Furthermore, to increase safety, a blade guard assembly 504 is provided on the side of the disc cutter 501. The blade guard assembly is fixed to the cutting arm by bolts and a preset gap is left between it and the disc cutter 501. When the disc cutter 501 is deformed to both sides under force, the blade guard assembly can limit its deformation range and ensure safety.

[0053] Because the disc blade 501 generates a lot of heat due to friction when cutting pigs at high speed, in order to reduce the temperature of the disc blade 501 during the cutting process and clean the cutting surface to remove blood and impurities, several spray cooling components 506 are installed on the surface of the frame 1 corresponding to the cutting area. The nozzle angle is adjustable, and water is continuously sprayed onto the cutting area during the cutting process to reduce the temperature of the blade and pork, so as to avoid affecting the cutting effect and pork quality due to heat.

[0054] Furthermore, in order to maintain the integrity of the pig's tail during the splitting process, the auxiliary components also include a pig tail-pulling component 505, which is fixedly connected to the lower part of the blade guard component. This component has a groove structure to accommodate the pig's tail. Before the disc blade 501 cuts to the pig's tail, the pig's tail can be pulled apart to both sides to ensure the integrity of the pig's tail.

[0055] The drive mechanism 2 provides power to the cutting mechanism 5, achieving stable rotation of the disc cutter 501 through multi-stage transmission. The drive mechanism 2 includes a motor 201, a first bearing housing assembly, a first pulley assembly 202, and a second pulley assembly 203. The first pulley assembly 202 is driven by the motor 201 and undertakes the initial transmission task of transferring power from the motor 201 to the core execution component of the equipment. The second pulley assembly 203 is connected to the drive shaft of the disc cutter 501 and is responsible for ultimately transmitting power to the disc cutter 501. The first pulley assembly 202 and the second pulley assembly 203 are connected via a drive shaft to transmit power from the motor 201.

[0056] The layout of the two pulley sets can adapt to the spatial layout, allowing components such as the motor 201 and the disc cutter 501 to be reasonably distributed according to the design of the frame 1. At the same time, the use of pulley sets for transmission has the characteristics of smooth transmission and low noise compared to gear transmission and other methods. In addition, it can effectively buffer and absorb vibration during power transmission, improve the overall stability of the equipment operation, and reduce the impact of vibration on cutting accuracy and meat quality.

[0057] Furthermore, to facilitate equipment maintenance and replacement, a tensioning assembly 204 is also provided below the first pulley group 202. By rotating the adjusting screw, the tensioning wheel is pushed to press the V-belt, thereby adjusting the belt tension and facilitating belt installation and replacement.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
