Description

Technical Field

[0001] This utility model belongs to the field of sausage packaging technology, specifically relating to an automatic heating and sealing machine for sausage outer packaging. Background Technology

[0002] Sausage is a food made using very ancient food production and meat preservation techniques. It is a long, cylindrical tube made by mincing animal meat into strips and stuffing it into casings. Sausages are made by stuffing seasoned meat into the small intestines of pigs or sheep and then drying them. After the sausages are made, they are usually packaged in bags. However, the opening of the bag needs to be sealed with a sealing machine. But some existing sealing machines often have certain shortcomings and therefore need to be improved.

[0003] Chinese patent CN213921745U discloses a wet wipe outer packaging sealing machine, which reduces the labor intensity of manual labor, enables automatic sealing of outer packaging, and improves work efficiency. The machine includes a support frame, a connecting plate, a first roller, a second roller, a first conveyor belt, a support plate, a third rotating shaft, a first support plate, a first motor, a first roller, a second roller, a third roller, a fourth roller, a lower conveyor belt, a fourth rotating shaft, a first pressure roller, a second pressure roller, a third pressure roller, a fourth pressure roller, an upper conveyor belt, a second support plate, and a second motor. The connecting plate is fixedly mounted on the support frame. The first roller has first rotating shafts at both its front and rear ends, and two sets of first rotating shafts are fixedly mounted at the front and rear ends of the first roller, respectively. The first roller is rotatably mounted on the upper left side of the support frame via the two sets of first rotating shafts. The second roller has second rotating shafts at both its front and rear ends, and the first rotating shafts are connected to an external motor.

[0004] However, although the above-mentioned technical solution can achieve the purpose of sealing the outer packaging, the wet wipes have a certain weight when packaged, and the wet wipes will move in a certain position when moving with the conveyor belt. This will cause the outer packaging to be displaced at the sealing point, resulting in misalignment during sealing heating, or even sealing failure. Therefore, it has certain limitations in use.

A heating plate 13 is arranged inside the strip cavity 11. The guide plate 2 allows the packaged sausages to slide down automatically, and workers can collect them at the bottom using a collection device. The conveyor belt 3 transports the sausages after they are wrapped in the packaging bag. The servo motor 5 provides a certain driving force for the rotation of the threaded rod 6. The threaded rod 6 and the threaded sleeve 7 allow the square block 8 and the hydraulic rod 9 to move with it. The hydraulic rod 9 allows the extrusion plate 10 to rise or fall a certain distance. The pressing roller 12 presses the area of ​​the packaging bag that needs to be sealed. The heating plate 13 melts the adhesive at the sealing area of ​​the packaging bag, facilitating subsequent extrusion sealing.

[0024] Two guide grooves 19 are formed in the middle of the inner wall of the fixed cavity 4. Sliding strips are fixedly connected to both sides of the square block 8, and the sliding strips slide inside the guide grooves 19. The guide grooves 19 provide a certain sliding space for the sliding strips, allowing the square block 8 to slide.

[0025] A slot is provided at the top of the surface of the housing 1, and a control panel is installed inside the slot. The control panel is electrically connected to the servo motor 5, the hydraulic rod 9 and the heating plate 13 respectively.

[0026] Example 2:

[0027] Please see Figure 1 and Figure 2 As shown, two grooves 14 are formed on the inner sidewall of the strip cavity 11. A slider 15 is slidably connected inside the groove 14. A rotating rod 18 is rotatably mounted inside the slider 15, and the rotating rod 18 is fixed and passes through the inside of the pressing roller 12. Through the arrangement of the grooves 14 and the slider 15, the rotating rod 18 can move up and down with the roller while ensuring that the rotating rod 18 can rotate, thereby causing the pressing roller 12 to rotate.

The compression spring 17 is designed so that after the slider 15 moves upward a certain distance and compresses the compression spring 17, it can automatically return to its original position.

[0030] The working principle of this utility model is as follows: Workers pre-package the sausages in bags, then position the top of the bag, slightly to the left of the area to be sealed, below the extrusion plate 10. At this point, the worker activates the hydraulic rod 9 and heating plate 13. The output of the hydraulic rod 9 drives the extrusion plate 10 downwards, squeezing the area to be sealed to the left. Then, the worker activates the conveyor belt 3 and servo motor 5. The output of the servo motor 5 drives the threaded rod 6 to rotate, causing the threaded sleeve 7 to slide to the left. This causes the square block 8 to move to the left along with the threaded rod 7. The hydraulic rod 9 and extrusion plate 10 then move to the left via the conveyor belt 3 until the area to be sealed is below the heating plate 13. The adhesive at this sealing point is then heated and melted. The sausages are then conveyed to the bottom of the pressing roller 12, where the pressing roller 12 squeezes the adhesive at the sealing point, bonding it together. Finally, the sausages are transported to the guide plate 2 via the conveyor belt 3, where workers collect them using a collection device.
