A cattle splitting device with quick tool change module

Abstract

This invention provides a cattle splitting device with a quick-change blade module, relating to the slaughtering field. The cattle splitting device includes a fixed half-piece and a splitting half-piece. The fixed half-piece is connected to a driving pulley and a driven pulley, respectively. The outer surfaces of the driving and driven pulleys are connected via a saw blade drive. A guide mechanism for twisting the saw blade is located at the bottom end of the fixed half-piece, on the side where the driven and driving pulleys are close to each other. The guide mechanism includes a semi-toothed ring, and parallel rollers are arranged on the inner ring of the semi-toothed ring. This cattle splitting device with a quick-change blade module rotates the semi-toothed ring by a sliding rack plate, which in turn rotates the rollers, causing the saw blade to twist. This solves the problem in the prior art where the saw blade needs to be actively twisted to pass through a fixed guide structure during the splicing process, leading to bending and twisting of the saw blade and increased blade changing time.

Description

Technical Field

[0001] This invention relates to the field of slaughtering equipment, specifically to a cattle splitting device with a quick-change knife module. Background Technology

[0002] Splitting saws are crucial for animal slaughterhouses. To facilitate transportation, storage, processing, and sales, animal carcasses that have been gutted and cleaned, and then dehaired or skinned, need to be split in half. Because this process involves dividing a dehaired or skinned animal carcass in two, it is commonly called splitting, and the equipment used is called a splitting saw. Belt splitting saws are increasingly being adopted due to their lightweight design, high efficiency, and hygienic operation.

[0003] Existing technology discloses a belt splitting saw (CN111631247A), comprising: a drive end, including a motor, a transmission device, and a drive wheel; the motor is connected to the drive wheel via the transmission device, enabling the motor to drive the drive wheel to rotate; a driven end, including a driven wheel with a diameter one-quarter to three-quarters the diameter of the drive wheel; a saw blade, which wraps around the drive wheel and the driven wheel, and drives the driven wheel to rotate together when the drive wheel rotates; and two guide blocks, including a first guide block and a second guide block, the first guide block being disposed on the side of the drive end closer to the driven end, and the second guide block being disposed on the side of the driven end closer to the drive end. By adopting the above technical solution, this splitting saw makes the diameter of the driven wheel smaller than the diameter of the drive wheel, thus making it easier for the driven end to be inserted between the suspension point of the torso and the pubic bone, facilitating splitting operations using the belt splitting saw.

[0004] However, when replacing the saw blade, the device first requires disassembling the outer casing, then loosening the driven wheel, and removing the saw blade. During installation, because the guide block is set to twist the saw blade, the twisted saw blade is elastic. During installation, the saw blade is easy to detach from the driven wheel and the driving wheel. Especially during the tensioning process, one hand needs to protect the saw blade to prevent it from detaching, and the other hand needs to adjust the tension. Therefore, replacing the saw blade is quite time-consuming. In view of this, the present invention proposes a cow splitting device with a quick blade changing module. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a saw blade splitting device with a quick blade changing module, which solves the problem of low efficiency and wasted time in changing saw blades mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a saw-splitting device with a quick-change blade module, comprising a fixed half-piece and a split half-piece, which are connected to form a frame. A driven pulley is provided at the front end of the fixed half-piece near the split half-piece, and a driving pulley is provided at the same end. The outer surfaces of the driving and driven pulleys are connected by a saw blade drive. A guide mechanism for twisting the saw blade is provided at the bottom end of the fixed half-piece on the side where the driven and driving pulleys are close to each other. The guide mechanism includes a half-tooth ring, with parallel rollers arranged on the inner ring of the half-tooth ring. The saw blade passes between the two rollers. The fixed half-piece has a groove for accommodating the half-tooth ring and positioning the teeth of the half-tooth ring on the outside of the fixed half-piece. A rack plate that meshes with the half-tooth ring is slidably connected to the outside of the fixed half-piece. A positioning mechanism for restricting the movement of the rack plate is provided on the outside of the fixed half-piece.

[0007] Preferably, the fixed half-piece has a limiting groove to accommodate the sliding and rotation of the driven pulley. The driven pulley is rotatably connected to a sliding frame with an internal sleeve bearing. The sliding frame is slidably connected to the fixed half-piece. Limiting sleeves are fitted on the outer surfaces of both the fixed half-piece and the split half-piece. The limiting sleeve near the driven pulley extends into the interior of the frame and protrudes to form a pressing block. The pressing block presses the sliding frame, causing the driven pulley to slide away from the driving pulley. Insertion grooves are provided on both sides inside the two limiting sleeves. Insertion half-rings are rotatably connected to the outer sides of both the fixed half-piece and the split half-piece. The insertion half-rings are inserted into the insertion grooves by swinging.

[0008] Preferably, the end of the extrusion block facing the sliding frame is provided with an extrusion sleeve. The extrusion sleeve is slidably connected to the extrusion block through two guide rods. A threaded shaft is rotatably connected to the middle of the extrusion sleeve. The threaded shaft passes through the extrusion block and extends to the outside of the frame. The threaded shaft is threadedly connected to the extrusion block.

[0009] Preferably, the positioning mechanism includes a snap-fit ​​sleeve that slides up and down on the outside of the fixed half piece. The snap-fit ​​sleeve is fixedly connected to the rack plate. The outer side of the limiting sleeve is provided with a snap-fit ​​protrusion that cooperates with the snap-fit ​​sleeve. When the limiting sleeve is installed on the surface of the fixed half piece and the split half piece, the snap-fit ​​protrusion and the snap-fit ​​sleeve form a snap-fit.

[0010] Preferably, a positioning post is fixed on the side of the split half piece close to the fixed half piece. The positioning post extends outward toward the fixed half piece, and each positioning post has an integrally formed snap ring at its end. A sliding baffle is also integrally formed on the snap ring. The sliding baffle has an arc-shaped structure at the position corresponding to the snap ring and can be inserted into the snap ring to form a snap.

[0011] Preferably, positioning ring grooves are provided on both sides of the semi-toothed ring, and a positioning semi-ring block sleeved inside the positioning ring groove is fixed to the inner wall side of the fixed half piece.

[0012] Preferably, the outer side of the fixed half piece is provided with a guide rail, and the rack plate, snap-fit ​​sleeve and sliding baffle form an integrated structure and are slidably connected to the guide rail.

[0013] Preferably, the driven pulley and the driving pulley are rotatably engaged with the fixed half piece, and the split half piece is equipped with a power source that drives the driving pulley to rotate. The output end of the power source is provided with a driving block that engages with the driving pulley. One split half piece corresponds to multiple fixed half pieces.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention uses a sliding rack plate to drive the semi-toothed ring to rotate, which in turn drives the roller to rotate, thereby causing the saw blade to twist. During installation, the opening direction of the guide mechanism is the same as the installation direction of the saw blade, which makes it easier to install the saw blade. After installation, the saw blade is twisted, thus avoiding the problem of the elasticity being difficult to fit when twisting the saw blade first.

[0016] 2. An extrusion sleeve is provided at one end of the extrusion block facing the sliding frame. The extrusion sleeve is slidably connected to the extrusion block through two guide rods. A threaded shaft is rotatably connected to the middle of the extrusion sleeve. The threaded shaft passes through the extrusion block and extends to the outside of the frame. The threaded shaft is threadedly connected to the extrusion block. By driving the threaded shaft to rotate, the extrusion sleeve can be driven to move relative to the extrusion block, thereby enabling fine adjustment of the tension.

[0017] 3. The driven pulley and the driving pulley are engaged with the fixed half-plate. The split half-plate is equipped with a power source that drives the driving pulley to rotate. The output end of the power source is equipped with a drive block that engages with the driving pulley. One split half-plate corresponds to multiple fixed half-plates. This arrangement allows all the parts involved in the cutting to be installed on the fixed half-plate. During the replacement process, the fixed half-plate can be replaced directly, thus separating the disassembly and blade replacement steps, thereby reducing the blade replacement time. The removed fixed half-plate can be used to replace the saw blade during downtime. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0030] like Figure 1-8As shown, a ox-splitting device with a quick-change blade module includes a fixed half-blade 1 and a split half-blade 2. The fixed half-blade 1 and the split half-blade 2 are connected to form a frame. A driven pulley 3 is provided at the front end of the fixed half-blade 1 near the split half-blade 2, and a driving pulley 4 is provided at the same side of the fixed half-blade 1 near the split half-blade 2. The outer surfaces of the driving pulley 4 and the driven pulley 3 are connected by a sleeve saw blade 5. The driving pulley 4 is driven to rotate by a power source 21, and the driven pulley 3 is driven to rotate by friction transmission through the saw blade 5. Both the driving pulley 4 and the driven pulley 3 are friction wheels. A guide mechanism 6 for torsion saw blade 5 is provided at the bottom end of the fixed half-blade 1 on the side where the driven pulley 3 and the driving pulley 4 are close to each other.

[0031] The guide mechanism 6 includes a semi-toothed ring 601. The inner ring of the semi-toothed ring 601 is provided with parallel rollers 602. The saw blade 5 passes between the two rollers 602. The fixed half plate 1 has a groove that accommodates the semi-toothed ring 601 and makes the teeth of the semi-toothed ring 601 located on the outside of the fixed half plate 1. The outer side of the fixed half plate 1 is slidably connected to a rack plate 603 that meshes with the semi-toothed ring 601. The outer side of the fixed half plate 1 is provided with a positioning mechanism 64 that restricts the movement of the rack plate 603.

[0032] The positioning mechanism 64 can be threadedly connected to the fixed half-piece 1 with screws at the extreme position of the rack plate 603. During use, the saw blade 5 is sleeved on the outer ring of the driving pulley 4 and the driven pulley 3, and the saw blade 5 is driven by two parallel rollers 602. The sliding rack plate 603 drives the half-tooth ring 601 to rotate, thereby driving the rollers 602 to rotate, which in turn causes the saw blade 5 to twist. In the prior art, the saw blade 5 needs to be actively twisted during the sleeve process. However, the saw blade 5 is not easy to sleeve after bending and twisting, which directly affects the longer tool change time. Compared with the traditional fixed guide structure, the guide mechanism 6 of this application can rotate. During the installation process, the opening direction of the guide mechanism 6 is the same as the installation direction of the saw blade 5, which can facilitate the installation of the saw blade 5. After the installation is completed, the saw blade 5 is twisted, thereby avoiding the problem of the elasticity of the saw blade 5 being difficult to sleeve due to twisting during the sleeve process.

[0033] The fixed half piece 1 has a limiting groove 7 to accommodate the sliding and rotation of the driven pulley 3. The driven pulley 3 is rotatably connected to a sliding frame 8 with an internal sleeve bearing. The sliding frame 8 is slidably connected to the fixed half piece 1. The sliding frame 8 slides horizontally relative to the fixed half piece 1 along the axis of the driven pulley 3 and the driving pulley 4. The outer surfaces of the fixed half piece 1 and the split half piece 2 are fitted with limiting sleeves 9. The limiting sleeve 9 near the driven pulley 3 extends into the interior of the frame and protrudes to form a pressing block 10. The pressing block 10 presses the sliding frame 8, causing the driven pulley 3 to slide away from the driving pulley 4. The two sides of the interior of the two limiting sleeves 9 are provided with insertion grooves 11. The outer sides of the fixed half piece 1 and the split half piece 2 are rotatably connected with insertion half rings 12. The insertion half rings 12 are inserted into the insertion grooves 11 by swinging. The distance between the driven pulley 3 and the driving pulley 4 can be adjusted by the squeezing block 10 inside the limiting sleeve 9 driving the sliding frame 8, thereby adjusting the tension of the saw blade 5. The limiting sleeve 9 is sleeved on the outer surface of the fixed half 1 and the split half 2, which can connect the fixed half 1 and the split half 2 at the same time.

[0034] Furthermore, in this embodiment, the end of the extrusion block 10 facing the sliding frame 8 is provided with an extrusion sleeve 13. The extrusion sleeve 13 is slidably connected to the extrusion block 10 through two guide rods. The middle part of the extrusion sleeve 13 is rotatably connected to a threaded shaft 14. The threaded shaft 14 passes through the extrusion block 10 and extends to the outside of the frame. The threaded shaft 14 is threadedly connected to the extrusion block 10. By driving the threaded shaft 14 to rotate, the extrusion sleeve 13 can be driven to move relative to the extrusion block 10, thereby enabling fine adjustment of the tension.

[0035] The positioning mechanism 64 in this embodiment includes a snap-fit ​​sleeve 641 that slides vertically and vertically on the outside of the fixed half-piece 1. The snap-fit ​​sleeve 641 is fixedly connected to the rack plate 603. The outer side of the limiting sleeve 9 is provided with a snap-fit ​​protrusion 642 that cooperates with the snap-fit ​​sleeve 641. In the initial state, the snap-fit ​​sleeve 641 is located at the bottom of the fixed half-piece 1. At this time, the saw blade 5 is installed, and the saw blade 5 passes between the two rollers 602. After the saw blade 5 is installed, the snap-fit ​​sleeve 641 is on the fixed half-piece 1. Sliding upwards, the rack plate 603 engages with the half-tooth ring 601, which in turn drives the half-tooth ring 601 to rotate. After the half-tooth ring 601 rotates 90°, the snap-fit ​​sleeve 641 remains stationary in this position. The limiting sleeve 9 is installed horizontally onto the surfaces of the fixed half-piece 1 and the split half-piece 2. The snap-fit ​​protrusion 642 engages with the snap-fit ​​sleeve 641, thereby limiting the rack plate 603. It should be noted that in this embodiment, the limiting sleeve 9 can only slide horizontally relative to the fixed half-piece 1.

[0036] A positioning post 15 is fixed on the side of the split half piece 2 near the fixed half piece 1. The positioning post 15 extends outward toward the fixed half piece 1, and each positioning post 15 has an integrally formed snap ring 16 at its end. A sliding baffle 17 is also integrally formed on the snap sleeve 641. The sliding baffle 17 has an arc-shaped structure at the position corresponding to the snap ring 16 and can be inserted into the snap ring 16 to form a snap. This arrangement can fix the fixed half piece 1 and the split half piece 2 and prevent them from separating.

[0037] The half-tooth ring 601 has positioning ring grooves 18 on both sides. The inner wall of the fixed half piece 1 is fixed with a positioning half-ring block 19 that is sleeved inside the positioning ring groove 18. This arrangement can support the half-tooth ring 601 and ensure that the half-tooth ring 601 can rotate.

[0038] A guide rail 20 is provided on the outer side of the fixed half piece 1. The rack plate 603, the snap-fit ​​sleeve 641 and the sliding baffle 17 form an integrated structure and are slidably connected to the guide rail 20. This arrangement can limit the sliding direction of the rack plate 603, the snap-fit ​​sleeve 641 and the sliding baffle 17 to prevent shaking.

[0039] Driven pulley 3 and drive pulley 4 are rotatably engaged with fixed half-plate 1. Split half-plate 2 is equipped with a power source 21 that drives drive pulley 4 to rotate. The output end of power source 21 is provided with a drive block 22 that engages with drive pulley 4. One split half-plate 2 corresponds to multiple fixed half-plates 1. With this arrangement, all parts involved in cutting can be installed on fixed half-plate 1. During the replacement process, fixed half-plate 1 can be replaced directly, thereby separating the disassembly step and the blade replacement step, thus reducing the blade replacement time. The replaced fixed half-plate 1 can be used to replace the saw blade 5 during idle time.

[0040] In use, firstly, the swinging insertion half-ring 12 separates from the insertion slot 11, and the limiting sleeve 9 is removed from between the fixed half-piece 1 and the split half-piece 2. At this time, the pressing block 10 no longer presses the sliding frame 8, and the driven pulley 3 resets under the elastic action of the saw blade 5. Then, the sliding rack plate 603 drives the snap-fit ​​sleeve 641 and the sliding baffle 17 to move downward, bringing two effects: the snap-fit ​​sleeve 641 moves downward and separates from the snap-fit ​​ring 16, and the fixed half-piece 1 and the split half-piece 2 can be separated. At the same time, the rack plate 603 moves, which can drive the half-tooth ring 601 to rotate, so that the torsional deformation of the saw blade 5 disappears. The split half-piece 2 can be removed, and the loose saw blade 5 can be removed and replaced. At this time, the opening of the guide mechanism 6 is in the same direction as the sleeve, and the driven pulley 3 is in an untensioned state. The saw blade 5 is directly fitted between the driven pulley 3, the driving pulley 4, and the two rollers 602. Then, the split half 2 and the fixed half 1 are joined together, the rack plate 603 is pulled upward, and the snap-fit ​​sleeve 641 is moved upward to snap into the snap-fit ​​ring 16. At this time, the fixed half 1 and the split half 2 are initially fixed. The saw blade 5 has now completed a 90° twist. Then, the limiting sleeve 9 is fitted onto the outer surface of the fixed half 1 and the split half 2, and the limiting sleeve 9 and the pressing block 10 are pushed to move and press the sliding frame 8. The driven pulley 3 is kept taut by the sliding frame 8. The limiting sleeve 9 snaps into the snap-fit ​​sleeve 641 to restrict its up and down movement. The swinging insertion half ring 12 is inserted into the insertion groove 11, thereby restricting the back and forth movement of the limiting sleeve 9. The saw blade 5 can then be quickly replaced.
