Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pork processing, specifically relating to an automatic pork carcass cutting and positioning device. Background Technology
[0002] In existing pork cutting equipment, a common structure mainly includes a transverse powered roller assembly, a longitudinal powered roller assembly, and a fixed circular saw. The transverse powered roller assembly carries and drives half of the pig carcass to move laterally to adjust the cutting position. The circular saw is usually located in the middle of the transverse roller assembly, with longitudinal roller assemblies on either side for conveying meat pieces of different sizes.
[0003] In actual use, operators place the pig carcass on the transverse rollers and rely on experience and visual judgment to determine its position before proceeding with the subsequent carcass cutting. Because the equipment relies entirely on the operator's experience for visual positioning, it cannot pinpoint the endpoint of the pig carcass's transverse movement. This makes it difficult to control the starting position of each cut, easily leading to large fluctuations in the size of the cut meat pieces, failing to meet the requirements of product standardization. Utility Model Content
[0004] The purpose of this invention is to provide an automatic cutting and positioning device for pork carcasses, which aims to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic pork carcass cutting and positioning device includes a positioning component, comprising a support platform with support legs fixedly connected to its bottom, a cutting blade disposed on the outside of the support platform, a transverse power roller disposed inside the support platform, a first longitudinal power roller disposed inside the support platform, a second longitudinal power roller disposed inside the support platform, and a positioning plate slidably connected to the top of the support platform. The pork carcass is positioned by contacting the positioning plate. A housing is fixedly connected to the bottom of the second longitudinal power roller, and an adjustment component is disposed inside the housing. An auxiliary component includes a movable plate disposed inside the housing, an abutment component disposed outside the movable plate, and a compression component disposed outside the movable plate.
[0006] In a preferred embodiment of this utility model, the adjustment assembly includes an extension cylinder fixedly connected to the left end of the housing. A threaded column is rotatably connected inside the extension cylinder and is rotatably connected to the housing. A handle is fixedly connected to the right end of the threaded column. A threaded block is threadedly connected to the outside of the threaded column. A U-shaped rod is fixedly connected to the right end of the threaded block and is slidably connected to the housing. The U-shaped rod is fixedly connected to a positioning plate. A scale mark is provided on the outside of the U-shaped rod. A support block is fixedly connected to the top of the support platform, and the U-shaped rod is slidably connected inside the support block.
[0007] As a preferred embodiment of this utility model, a through groove is provided inside the extension cylinder at the position corresponding to the threaded block, and the threaded block is slidably connected in the through groove.
[0008] In a preferred embodiment of this utility model, the abutting component includes an extension post fixedly connected to the right end of the movable plate, the extension post being slidably connected to the housing, a first abrasive block being fixedly connected to the right end of the extension post, a second abrasive block being fixedly connected to the outside of the threaded post, the first abrasive block contacting the second abrasive block, a guide rod being fixedly connected to the inner wall of the housing, and an extension block being fixedly connected to the outside of the movable plate, the extension block being elastically connected to the housing via a spring.
[0009] As a preferred embodiment of this utility model, a through hole is provided inside the extension block at a position corresponding to the guide rod, and the guide rod is slidably connected in the through hole.
[0010] In a preferred embodiment of this utility model, the extrusion assembly includes an inclined plate fixedly connected to the top of the movable plate, a U-shaped plate slidably connected to the inner wall of the housing, an extrusion block fixedly connected to the inner wall of the U-shaped plate, and a U-shaped pull rod fixedly connected to the bottom of the U-shaped plate.
[0011] As a preferred embodiment of this utility model, a through hole is provided at the bottom of the housing corresponding to the position of the U-shaped tie rod, and the U-shaped tie rod is slidably connected in the through hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up positioning components, the problem of the lack of positioning function in existing technologies is effectively solved. Operators can drive the threaded column to rotate by turning the handle, and with the help of the scale, the position of the positioning plate can be precisely adjusted. This structure allows the end of the pig carcass to abut against the positioning plate at the preset position when it moves on the transverse power roller, thereby ensuring the consistency of the starting point of each cut, overcoming the problem of uneven meat size caused by relying on manual visual positioning, and significantly improving the product standardization level and yield.
[0013] 2. The auxiliary components provide a reliable locking function for the threaded column, effectively preventing accidental displacement of the positioning plate due to vibration and other factors during equipment operation. The spring force pushes the moving plate and the first abrasive block, making them closely contact the second abrasive block. The friction between the contact surfaces effectively suppresses the unexpected rotation of the threaded column, thus ensuring the stability of the positioning plate position. The U-shaped pull rod drives the extrusion block to move down. With the cooperation of the inclined plate, the inclined surface forces the moving plate to compress the spring and drive the first abrasive block to disengage from the contact with the second abrasive block, thereby releasing the lock for adjustment.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0017] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides an automatic pork carcass cutting and positioning device, including a positioning component, including a support platform 10, a support leg 11 fixedly connected to the bottom of the support platform 10, a cutting blade 12 disposed on the outside of the support platform 10, a transverse power roller 13 disposed inside the support platform 10, a first longitudinal power roller 14 disposed inside the support platform 10, a second longitudinal power roller 15 disposed inside the support platform 10, a positioning plate 16 slidably connected to the top of the support platform 10, and the pork carcass is positioned by contacting the positioning plate 16. A housing 17 is fixedly connected to the bottom of the second longitudinal power roller 15, and an adjustment component 18 is disposed inside the housing 17.
[0018] Specifically, the support platform 10 serves as the core load-bearing platform for installing various functional components. The transverse power roller 13 is responsible for conveying the pig carcass to the processing area. The first longitudinal power roller 14 and the second longitudinal power roller 15 are used to convey meat pieces of different sizes after cutting, respectively. The cutting blade 12 completes the segmentation of the pig carcass. The positioning plate 16 serves as an adjustable mechanical limit reference and contacts the end of the pig carcass to achieve positioning. In use, the operator first sets the position of the positioning plate 16 according to the cutting specifications through the adjustment component 18, and then places the pig carcass on the transverse power roller 13. After starting, the pig carcass is automatically conveyed to contact and position with the positioning plate 16. Finally, the cutting blade 12 completes the segmentation and outputs the meat through the longitudinal roller.
[0019] Furthermore, the adjustment assembly 18 includes an extension cylinder 181 fixedly connected to the left end of the housing 17. A threaded post 182 is rotatably connected inside the extension cylinder 181 and is rotatably connected to the housing 17. A handle 183 is fixedly connected to the right end of the threaded post 182. A threaded block 184 is threadedly connected to the outside of the threaded post 182. A U-shaped rod 185 is fixedly connected to the right end of the threaded block 184 and is slidably connected to the housing 17. The U-shaped rod 185 is fixedly connected to the positioning plate 16. A scale mark 186 is provided on the outside of the U-shaped rod 185. A support block 187 is fixedly connected to the top of the support platform 10, and the U-shaped rod 185 is slidably connected inside the support block 187. By rotating the handle 183, the threaded post 182 is driven to rotate, causing the threaded block 184 to move axially. This, in turn, pushes the positioning plate 16 to the target position indicated by the scale mark 186 via the U-shaped rod 185.
[0020] The extension cylinder 181 has a through groove at the position corresponding to the threaded block 184, and the threaded block 184 is slidably connected in the through groove. The through groove provides an axial guide path for the threaded block 184, preventing the threaded block 184 from rotating with the threaded post 182, ensuring that it only makes linear motion, and limiting the stroke range of the threaded block 184.
[0021] In use, when the cutting size needs to be adjusted, the operator turns the handle 183, which drives the threaded column 182 to rotate within the extension cylinder 181 and the housing 17. The threaded block 184, which is threadedly engaged with the threaded column 182, converts the rotational motion into linear motion and drives the U-shaped rod 185 to slide laterally under the guidance of the support block 187. The positioning plate 16, fixed to the end of the U-shaped rod 185, moves accordingly, and its position can be precisely set by the scale mark 186 set on the U-shaped rod 185. After the adjustment is completed, the pig carcass is placed on the transverse power roller 13 and moves with it until its end contacts the positioning plate 16, thereby precisely stopping at the preset cutting starting position, ensuring positioning accuracy. Then, the pig carcass is pushed forward, and with the cooperation of the cutting blade 12, the first longitudinal power roller 14, and the second longitudinal power roller 15, the pig carcass is cut. The cut meat pieces are conveyed by the second longitudinal power roller 15 to the subsequent conveyor line for subsequent segmented cutting of the pig carcass.
[0022] Example 2 Reference Figures 4-5 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides auxiliary components, including a movable plate 20 disposed inside the housing 17, an abutting component 21 disposed outside the movable plate 20, and a pressing component 22 disposed outside the movable plate 20.
[0023] Furthermore, the contact component 21 includes an extension post 211 fixedly connected to the right end of the movable plate 20. The extension post 211 is slidably connected to the housing 17. A first abrasive block 212 is fixedly connected to the right end of the extension post 211. A second abrasive block 213 is fixedly connected to the outside of the threaded post 182. The first abrasive block 212 contacts the second abrasive block 213. A guide rod 214 is fixedly connected to the inner wall of the housing 17. An extension block 215 is fixedly connected to the outside of the movable plate 20. The extension block 215 is elastically connected to the housing 17 by a spring 216. It is particularly noteworthy that the movable plate 20 does not contact the housing 17 when the first abrasive block 212 contacts the second abrasive block 213. The extension post 211 transmits the linear motion of the moving plate 20 to the first abrasive block 212. The first abrasive block 212 and the second abrasive block 213 generate braking torque through frictional contact. The guide rod 214 provides vertical motion guidance for the moving plate 20. The extension block 215 acts as a force transmission component for the spring 216, which provides continuous clamping force to maintain the locked state. In the locked state, the spring 216 pushes the moving plate 20 through the extension block 215, causing the first abrasive block 212 to press tightly against the second abrasive block 213, thereby locking the threaded post 182 using frictional force.
[0024] The extension block 215 has a through hole at the position corresponding to the guide rod 214, and the guide rod 214 is slidably connected in the through hole. The through hole on the extension block 215 and the guide rod 214 form a sliding pair, ensuring that the moving plate 20 maintains a linear motion trajectory during the compression or release of the spring 216, and avoiding jamming or wear caused by skew.
[0025] Furthermore, the extrusion assembly 22 includes an inclined plate 221 fixedly connected to the top of the movable plate 20, a U-shaped plate 222 slidably connected to the inner wall of the housing 17, an extrusion block 223 fixedly connected to the inner wall of the U-shaped plate 222, and a U-shaped pull rod 224 fixedly connected to the bottom of the U-shaped plate 222. Notably, the top of the U-shaped plate 222 does not contact the inner wall of the housing 17. The inclined plate 221 converts the vertical movement of the U-shaped plate 222 into the horizontal displacement of the movable plate 20. The U-shaped plate 222 serves as the mounting carrier and transmission component for the extrusion block 223, and the inclined surface of the extrusion block 223 cooperates with the inclined plate 221 to form a motion conversion mechanism. When adjustment is required, pulling down the U-shaped pull rod 224 causes the U-shaped plate 222 to move downwards, and the extrusion block 223 presses against the inclined plate 221 to generate a horizontal component force, driving the movable plate 20 to compress the spring 216 and unlock.
[0026] The bottom of the housing 17 has a through hole corresponding to the position of the U-shaped tie rod 224, and the U-shaped tie rod 224 is slidably connected in the through hole. The through hole at the bottom of the housing 17 provides vertical guidance for the U-shaped tie rod 224, limiting its movement trajectory.
[0027] In use, by moving the U-shaped pull rod 224 downward, the U-shaped plate 222 drives the pressing block 223 to move downward. The pressing block 223 presses the inclined surface of the inclined plate 221. As the plane of the pressing block 223 contacts the plane of the moving plate 20, the moving plate 20 will not reset. The inclined surface forces the moving plate 20 to compress the spring 216 and drive the first abrasive block 212 to disengage from the second abrasive block 213, thereby releasing the limiting work on the threaded column 182, thus facilitating the rotation of the handle 183. After the adjustment of the positioning plate 16 is completed, by moving the U-shaped pull rod 224 upward, the pressing block 223 moves away from the moving plate 20. With the cooperation of the spring 216, the moving plate 20 moves towards the handle 183, so that the first abrasive block 212 contacts the second abrasive block 213. The friction between the contact surfaces locks the threaded column 182, preventing it from rotating accidentally due to equipment vibration.
[0028] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
