Description

Technical Field

[0001] This utility model relates to the field of livestock slaughtering and processing equipment, specifically to a conveying device on a packaging line. Background Technology

[0002] The final packaging stage of a livestock slaughtering and processing line for pigs, cattle, and sheep involves bagging and labeling the cut carcasses. Traditionally, large pieces of meat and bone, such as ribs, spine, and leg bones, are typically transported from the cut carcasses to the packaging station via meat pens, where workers package and label them before placing them in the output bins. To improve processing efficiency, some manufacturers use conveyor belts to connect the loading and unloading lines; however, existing conveyor systems have the following drawbacks:

[0003] (1) The existing metal belt support frame forms a guide rail and belt that rub against each other for a long time, generating metal debris that contaminates meat products. Furthermore, the fixed belt support frame is prone to forming unsanitary dead corners that are difficult to clean thoroughly.

[0004] (2) The baffle structure has a single function and cannot adapt to materials of different sizes. The material sticks to the edge, causing the fork to deviate in positioning. This results in the material getting stuck between the fork and the packaging table, making it impossible to accurately push the material into the packaging table. Packaging personnel often need to intervene and manually adjust the material position. In addition, the connection between the baffle and the conveyor belt is prone to scratching the meat and retaining meat residue. (3) The wide conveyor belt is not only difficult to replace, but also hinders the leakage of liquid residue on the meat from the upstream cleaning process. Blood water remains on the conveyor belt, which poses a risk of bacterial growth after the meat is packaged. Although some conveying mechanisms adopt a multi-track and multi-belt structure, it is still difficult to quickly loosen and replace the belt and the support frame. Utility Model Content

[0005] The technical problem this utility model aims to solve is to provide a conveying device on a packaging line, which significantly improves the hygiene and ease of maintenance of the equipment through the combination of nylon support rails and tension wheel mechanism. The wide U-shaped groove and flange design reduce belt friction and, after multiple separate perforated conveyor belts are mounted, creates a large seepage space, effectively preventing blood and sewage from accumulating. The adjustable alignment baffle assembly precisely controls the inclination angle of the upper baffle through a rotating shaft, ensuring that meat products of different sizes are confined to the effective working area of ​​the forks. The tension wheel inclined groove mechanism allows for quick disassembly and assembly of the belt and support components, facilitating replacement. In addition, the bottom edge of the U-shaped outward-folding baffle eliminates the risk of material scratches, enabling the entire feeding and conveying process to achieve efficient and continuous operation while ensuring the hygiene and safety of the meat products.

[0006] This packaging line conveyor includes a feeding conveyor for conveying unpackaged materials, a discharging conveyor for conveying packaged materials, and several packaging platforms located inside and above the discharging conveyor. The feeding conveyor includes frames on both sides of the conveying direction, several supporting pipes welded between the two frames, several guide rail assemblies fixed to the supporting pipes for mounting conveyor belts, an alignment baffle assembly mounted on the outside of the frames, and several perforated conveyor belts mounted on the guide rail assemblies. Each guide rail assembly includes nylon support rails and a tensioning wheel mechanism fixed below the nylon support rails. A perforated conveyor belt is mounted on two adjacent nylon support rails, with adjacent perforated conveyor belts separated and spaced apart. The lower edge of the nylon support rails has a groove for fastening and connecting the supporting pipes, and the upper edge of the nylon support rails has a wide U-shaped groove to reduce belt friction. An upwardly protruding flange for supporting the conveyor belts is formed between adjacent wide U-shaped grooves. The alignment baffle assembly includes a lower baffle fixed on the outer frame and an upper baffle rotatably connected to the lower baffle via a hinge. The hinge is provided with a fastening knob for adjusting the tilt angle of the upper baffle.

[0007] Furthermore, the tensioning wheel mechanism includes a wheel seat connected below the nylon support rail and a tensioning wheel mounted on the wheel seat; the wheel seats are arranged in pairs below two adjacent nylon support rails, and the wheel seats have inclined grooves, with the wheel axles on both sides of the tensioning wheel respectively inserted into the inclined grooves of a pair of wheel seats.

[0008] Furthermore, the bottom of the upper baffle is U-shaped and flared outwards.

[0009] Furthermore, one side of the frame is equipped with a feeding motor and a drive roller for driving each perforated conveyor belt.

[0010] Specifically, the conveying plane of the feeding conveyor is flush with the packaging table and higher than the conveying plane of the unloading conveyor; a lifting conveyor is provided on the downstream side of the unloading conveyor for raising the discharge position; a fork is provided on the packaging table, and a proximity sensor is provided on the inner side of the fork.

[0011] The present invention relates to a conveying device for a packaging line, the advantages of which are as follows:

[0012] (1) By combining the nylon support rail and the tension wheel mechanism, the hygiene and maintenance convenience of the equipment are significantly improved. The wide U-shaped groove and flange design reduces belt friction and, after multiple separate perforated conveyor belts are mounted, forms a large amount of seepage space, effectively preventing blood and sewage from accumulating.

[0013] (2) The adjustable positioning baffle assembly precisely controls the tilt angle of the upper baffle through the rotating shaft, ensuring that meat products of different sizes are restricted to the effective working area of ​​the fork; in addition, the bottom edge of the U-shaped outward-folding baffle eliminates the risk of material scratching, so that the entire feeding and conveying process can achieve efficient and continuous operation while ensuring the hygiene and safety of meat products.

[0014] (3) The tension wheel slant mechanism can quickly detach the belt from the support mechanism through quick disassembly and assembly, thus facilitating replacement. Attached Figure Description

Each guide rail assembly 3 includes a nylon support guide rail 31 and a tensioning wheel mechanism 32 fixed below the nylon support guide rail 31. A... A perforated conveyor belt 5 is provided, with adjacent perforated conveyor belts 5 separated from each other and forming a gap; the lower edge of the nylon support guide rail 31 is provided with a groove 311 for fastening and connecting the support connecting pipe 2, and the upper edge of the nylon support guide rail 31 is provided with a wide U-shaped groove 312 to reduce belt friction, and a flange 313 protruding upward between adjacent wide U-shaped grooves 312 to support the conveyor belt; the wide U-shaped groove and flange design reduces belt friction, and after multiple separate perforated conveyor belts are hung, a large amount of seepage space is formed, effectively avoiding the retention of blood and sewage; the alignment baffle assembly 4 includes a lower baffle 41 fixed on the outer frame 1 and an upper baffle 42 rotatably connected to the lower baffle through a hinge 43, and the hinge 43 is provided with a fastening knob 431 for adjusting the tilt angle of the upper baffle 42. It is used to adjust the tilt angle of the upper baffle according to the width of the material so that the material is in the effective insertion area of ​​the shift fork.

[0035] Implementation method 2: such as Figure 6 , 8 As shown, the tensioning wheel mechanism 32 of the conveyor device on this packaging line includes a wheel seat 321 connected below the nylon support guide rail 31 and a tensioning wheel 322 mounted on the wheel seat 321. The wheel seats 321 are arranged in pairs below two adjacent nylon support guide rails 31, and each wheel seat 321 has a groove 323. The axles on both sides of the tensioning wheel 322 are respectively engaged in the grooves 323 of a pair of wheel seats 321. This facilitates the periodic removal of the tensioning wheels to replace contaminated conveyor belts, ensuring material hygiene standards. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0036] Implementation method 3: such as Figure 7 As shown, the bottom of the upper baffle 42 of the conveyor on this packaging line is U-shaped and outwardly flared. This forms an arc surface, which ensures smooth material conveying while preventing scratches on the material. The remaining structures and components are as described in Embodiment 1 and will not be repeated.

[0037] Implementation method 4: such as Figure 4As shown, the frame 1 of the conveyor device on this packaging line is equipped with a feeding motor 11 and a drive roller 12 for driving each perforated conveyor belt 5. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0038] Implementation method 5: such as Figure 1 , 2 As shown, the conveying plane of the feeding conveyor 100 of the conveying device on this packaging line is flush with the packaging table 300 and higher than the conveying plane of the unloading conveyor 200; a lifting conveyor 400 for raising the discharge position is provided on the downstream side of the unloading conveyor 200; a fork 301 is provided on the packaging table 300, and a proximity sensor is provided on the inner side of the fork. The proximity sensor is used to sense the meat material and send a signal to the PLC. The PLC drives the fork to push the material in and after the material is discharged, the fork resets. After packaging is completed, the operator actively controls the fork to push the material on the operating table into the discharge conveyor. The remaining structures and components are as described in Embodiment 1 and will not be described again.

[0039] During operation: Adjust the inward angle of the upper baffle 42 according to the size of the batch of meat materials, and tighten the fastening knob 43 to ensure that the material enters the effective area of ​​the fork at the conveyor position on the belt; the material enters the perforated conveyor belt 5 for conveying. During the process, the wide U-shaped groove 312 of the nylon support guide rail 31 reduces belt friction and reduces the risk of contamination. Liquid leaks down through the gap between adjacent guide rails to prevent stagnation and bacterial growth. The arc surface of the U-shaped outward-turning baffle guides the meat pieces to avoid surface scratches; the material is conveyed to each packaging station 3, and the fork 301 of the feeding conveyor mechanism 100 is intercepted by the packaging table 300 and rotated 90° clockwise to push the material into the table for packaging. After packaging is completed, the material is actively pushed by the fork 301 to the unloading conveyor mechanism 200 again at 90° clockwise. After being lifted by the lifting conveyor mechanism 400, the material is discharged to adapt to different specifications of packaging boxes. The fork 301 rotates 180° counterclockwise to the initial longitudinal position to intercept the next material.

[0040] This packaging line conveyor system significantly improves hygiene and ease of maintenance through a combination of nylon support rails and a tensioning wheel mechanism. The wide U-shaped groove and flange design reduce belt friction and, when multiple separate perforated conveyor belts are mounted, create ample seepage space, effectively preventing blood and waste from accumulating. The adjustable alignment baffle assembly precisely controls the upper baffle angle via a rotating shaft, ensuring that meat products of different sizes are confined to the effective working area of ​​the forks. The tensioning wheel inclined groove mechanism allows for quick disassembly and assembly of the belt and support components, facilitating replacement. Furthermore, the bottom edge of the U-shaped outward-folding baffle eliminates the risk of material scratches, enabling the entire feeding and conveying process to achieve efficient and continuous operation while ensuring the hygiene and safety of the meat products.
