Description

Technical Field

[0001] This utility model relates to the field of splitting machine technology, specifically to a splitting machine external clamping mechanism. Background Technology

[0002] Splitting pigs in half is a crucial step in slaughtering and processing, directly impacting meat yield and product value. Traditional splitting machines typically employ an external holding mechanism integrated with the splitting head. During operation, this mechanism must simultaneously perform multiple tasks, including lateral following, securing the pig carcass, and coordinating with the machine head's downward splitting motion. However, in actual assembly line production, pig carcasses often sway along the conveyor chain, and pigs vary significantly in size. Existing integrated structures have significant drawbacks. Limited by overall layout and power distribution, the holding force provided by the external holding mechanism is limited. For large pigs, it often fails to hold them securely, leading to displacement during splitting, resulting in improper splitting, bone fractures, or incomplete split surfaces, severely impacting yield and commercial value.

Detailed Implementation

[0014] Please see Figures 1-5 A splitting and external holding mechanism for a splitting machine, comprising: Frame 1, with a top frame 11 fixed at the upper end of frame 1; The horizontal synchronous belt assembly 2 is fixedly installed at the lower end of the top frame 11; The vertical frame assembly 3 is installed under the horizontal synchronous belt assembly 2, and the vertical frame assembly 3 is slidably connected to the top frame 11; Vertical synchronous belt assembly 4 fixed in vertical frame assembly 3; The retaining wheel assembly 5 is fixedly installed at the front end of the vertical synchronous belt assembly 4; The folding support frame assembly 6, installed on both sides of the vertical frame assembly 3, provides a stable installation base for the frame 1 and the top frame 11. The horizontal synchronous belt assembly 2 serves as the primary drive, responsible for the large-scale lateral (X-axis) movement of the entire mechanism along the pig carcass conveying direction to achieve initial tracking. The vertical frame assembly 3 serves as the main load-bearing body, and its sliding connection ensures smooth lateral movement. The vertical synchronous belt assembly 4 serves as the secondary drive, installed on the vertical frame assembly 3, responsible for driving the holding wheel assembly 5 to vertically (Z-axis) lift and lower to align with the pig carcass height. The folding support frame assembly 6 is installed on both sides of the vertical frame assembly 3 as a tertiary actuator to clamp the pig carcass from both sides. This split and layered structural design makes the external holding mechanism completely independent in terms of spatial movement and force application, providing a mechanical basis for performing complex and stable collaborative operations.

[0015] The horizontal synchronous belt assembly 2 includes a motor 21, a synchronous pulley 22, and a synchronous belt 23. There is a pair of synchronous pulleys 22, which are rotatably connected to the left and right sides of the lower end of the top frame 11. The synchronous belt 23 is connected between the synchronous pulleys 22. The motor 21 is located in front of one of the synchronous pulleys 22 and is fixed to the lower end of the top frame 11. The output shaft of the motor 21 is fixed to one of the synchronous pulleys 22. When the control system issues a lateral movement command according to the sensor signal, the motor 21 starts and drives the synchronous pulley 22 fixed to it to rotate. Through the transmission of the synchronous belt 23, the synchronous pulley 22 on the other side rotates synchronously, thereby converting the rotational motion into the linear cyclic motion of the synchronous belt 23. Since the vertical frame assembly 3 is fixedly installed at the lower end of the synchronous belt 23, the movement of the synchronous belt 23 directly drives the entire vertical frame assembly 3, the vertical synchronous belt assembly 4, the wheel assembly 5, and the folding support assembly 6 together to perform precise lateral linear movement along the horizontal guide rail 12 fixed on the top frame 11, so as to achieve synchronous following with the speed of the pigs on the assembly line.

[0016] The vertical frame assembly 3 includes a vertical frame 31, horizontal guide blocks 32, vertical guide rails 33, and vertical guide blocks 34. The vertical frame 31 is fixed to the lower end of the synchronous belt 23. There are two sets of horizontal guide blocks 32, which are located on the front and rear sides of the synchronous belt 23 respectively. The horizontal guide blocks 32 are fixed to the upper end of the vertical frame 31. Horizontal guide rails 12 are fixed on both the front and rear sides of the lower end of the top frame 11. The horizontal guide blocks 32 and the horizontal guide rails 12 are slidably connected. The horizontal guide blocks 32 and the horizontal guide rails 12 on the top frame 11 form a sliding pair. This design ensures that the driving force transmitted from the horizontal synchronous belt assembly 2 can be smoothly converted into the lateral movement of the vertical frame 31. At the same time, through the cooperation of the two sets of horizontal guide blocks 32 and the horizontal guide rails 12, the lateral torque and torsional tendency generated by holding the pig are effectively resisted, ensuring the overall rigidity and motion stability of the mechanism when following at high speed and holding with strong force, and providing a solid foundation for precise vertical movement.

[0017] There are two vertical guide rails 33, which are fixed to the left and right sides of the front end of the vertical frame 31 respectively. There are two vertical guide blocks 34, which are slidably connected to the vertical guide rails 33 respectively. The wheel clamping assembly 5 is fixed to the front end of the vertical guide block 34. The vertical guide rails 33 and the vertical guide blocks 34 form a high-rigidity vertical guide pair. The wheel clamping assembly 5 is mounted on this guide pair through the vertical guide block 34. When the vertical synchronous belt assembly 4 drives the wheel clamping assembly 5 to move, the vertical guide block 34 slides up and down along the vertical guide rails 33, which strictly limits the movement trajectory of the wheel clamping assembly 5, so that it can only make precise vertical linear movements. The design of the two guide rails distributed on the left and right provides balanced support for the wheel clamping assembly 5, ensuring that it will not overturn or jam when the clamping force is applied, so as to stably transmit the strong vertical clamping force to the pig body.

[0018] The vertical synchronous belt assembly 4 includes a second motor 41, a second synchronous pulley 42, and a second synchronous belt 43. The second motor 41 is fixedly installed on the upper end of the vertical frame 31. There are two second synchronous pulleys 42, which are rotatably connected to the upper and lower sides of the middle of the vertical frame 31 respectively. The second synchronous belt 43 is connected between the second synchronous pulleys 42 and is located between the vertical guide rails 33 and fixed to the wheel clamping assembly 5. The second motor 41 is started according to the control command, driving the second synchronous pulleys 42 to rotate, thereby making the second synchronous belt 43 perform cyclical motion. Since the second synchronous belt 43 is fixedly connected to the wheel clamping assembly 5, the linear motion of the second synchronous belt 43 is directly converted into the up and down motion of the wheel clamping assembly 5 along the vertical guide rails 33. This design allows the wheel clamping assembly 5 to quickly adjust to the preset clamping position according to the height profile of the pig's back and maintain precise synchronous downward motion with the chopping head during the splitting process, ensuring constant pressure at the clamping point and avoiding slippage or tearing of the pig's body due to relative displacement.

[0019] The folding armrest assembly 6 includes a concave frame 61, a central connecting rod 62, side connecting rods 63, a surrounding frame 64, and a cylinder 65. The concave frame 61 is fixed to the rear end of the vertical frame 31. The central connecting rod 62 is rotatably connected to the middle of the lower rear end of the vertical frame 31. There is a pair of side connecting rods 63, which are rotatably connected to the two ends of the central connecting rod 62. There is a pair of surrounding frames 64, which are rotatably connected to the two sides of the lower end of the concave frame 61. The ends of the side connecting rods 63 are rotatably connected to the surrounding frames 64 on the same side. The cylinder 65 is located between the lower rear parts of the surrounding frames 64. The cylinder seat of the cylinder 65 is rotatably connected to one of the surrounding frames 64, and the end of the piston rod of the cylinder 65 is rotatably connected to the other surrounding frame 64. In the initial state, the piston rod of the cylinder 65 retracts, directly driving one of the surrounding frames 64. One enclosure 64 rotates, and under the linkage of the central connecting rod 62 and the two side connecting rods 63, the other enclosure 64 also rotates in the opposite direction in sync, so that the two enclosures 64 and the support frames 68 on them are in an open state and in a waiting position. When it is necessary to hug the chest, the piston rod of cylinder 65 extends and pushes the two enclosures 64 to move towards the center around their hinge point on the concave frame 61, thereby driving the support frames 68 installed at the front end to close from both sides of the pig's chest, forming an initial hug and support. This action occurs before the gripping wheel assembly 5 presses down to hug tightly, which is intended to stabilize the pig in the early stage of entering the splitting position, effectively suppressing its swaying with the production line, and creating conditions for subsequent precise splitting. Cylinder 65 is directly driven, with great power, and the action is fast and reliable.

[0020] The folding support frame assembly 6 also includes a second cylinder 66, a connecting frame 67, a support frame 68, and a connecting rod 69. The upper and lower sides of the front end of the enclosure 64 are rotatably connected to the support frames 68, and the sides of the support frames 68 are rotatably connected to the connecting rod 69. The uppermost support frame 68 is fixedly connected to the side of the connecting frame 67. The upper end of the connecting frame 67 is connected to the enclosure 64 by the second cylinder 66. The cylinder seat of the second cylinder 66 is rotatably connected to the enclosure 64, and the piston rod of the second cylinder 66 is rotatably connected to the connecting frame 67. After the enclosure 64 is clamped, the second cylinder 66 retracts, driving the connecting frame 67 to move, which in turn drives the uppermost support frame 68 fixed to it to rotate. Since all the support frames 68 are hinged and linked by the connecting rod 69, when one support frame 68 rotates, the other support frames 68 will move in coordination, so that a row of support frames 68 can rotate simultaneously to a horizontal state, increasing the contact area, dispersing pressure, stabilizing the pig's body, and avoiding local crushing injuries.

[0021] In summary, the independently driven horizontal synchronous belt assembly 2 enables the entire vertical frame assembly 3 to quickly and smoothly follow the pig's body laterally within a large stroke range. The vertical synchronous belt assembly 4 drives the holding wheel assembly 5 to precisely adjust its height to accommodate pigs of different sizes. The specially designed folding support assembly 6, driven by two-stage cylinders, first provides initial stabilization by holding the pig's chest from both sides, and then the holding wheel assembly 5 performs the final tightening, forming a graded stabilization mechanism that effectively suppresses the pig's swaying on the assembly line. This split design allows the outer holding mechanism to provide a holding force far greater than that of the traditional integrated structure, ensuring that even large pigs can be firmly fixed, thereby greatly improving the straightness and integrity of splitting, reducing bone damage and splitting defects. Through coordinated control with the machine head, the entire mechanism achieves full automation of following, holding, synchronous splitting, and resetting, significantly improving the production rhythm and overall quality stability of the splitting operation.
