Technical Field

[0001] The utility model relates to the technical field of agricultural and sideline product processing, and more specifically to a packaging and sealing structure for agricultural and sideline products. Background Art

[0002] Agriculture belongs to the primary industry, which refers to the industry that produces food and industrial raw materials by cultivating animals and plants. Agricultural and sideline products are by-products brought about by agricultural production, including agricultural, forestry, animal husbandry, sideline products, and fishery products. Each major category is divided into several subcategories. Sealing devices are often required in the production and processing of agricultural and sideline products.

[0003] In actual use, the existing agricultural and sideline products packaging sealing structure generally transports the agricultural and sideline products packaging bags to a fixed position through a conveyor belt, and then uses a hydraulic cylinder to push the heating plate to press and seal the open part of the packaging bag. This operation method can only seal multiple packaging bags in sequence, with low sealing efficiency and affecting the overall work efficiency. Therefore, there is an urgent need to improve the technology of the agricultural and sideline products packaging sealing structure to improve this equipment. Utility Model Content

The second U-shaped frame 10 is connected to one end of the conveyor belt 2 with four mounting seats 11 with equal spacing, and the bottom ends of the four mounting seats 11 are connected to two symmetrical connecting frames 12. A hydraulic rod 13 is embedded in the connecting frame 12, and a connecting plate 14 is fixed to the end of the hydraulic rod 13. An abutment mechanism is provided at the connecting plate 14, and the packaging bag is limitedly abutted between the two connecting plates 14 through the abutment mechanism. The connecting plate 14 is connected to a pressing plate 18 at one end away from the hydraulic rod 13, and the two pressing plates 18 at the bottom of the mounting seat 11 are arranged opposite to each other.

[0030] Agricultural and sideline product packaging bags can be placed between each set of limiting plates 4. Multiple agricultural and sideline product packaging bags are placed on the conveyor belt 2. Each set of limiting plates 4 separates the packaging bags from each other, so that the packaging bags move between the two connecting frames 12. The hydraulic rods 13 on the two connecting frames 12 work at the same time, driving the abutment plates 17 to pre-abut the two ends of the packaging bags, and while limiting and fixing the packaging bags, the packaging bags can also be placed in the middle position between the two connecting frames 12. At the same time, the hydraulic rods 13 continue to drive the abutment plates 17 to move, so that the springs 16 are compressed, and the abutment plates 17 move into the mounting sleeves 15. The pressing plates 18 are used to seal the open ends of the packaging bags, so that the purpose of sealing multiple packaging bags at the same time can be achieved, thereby improving the sealing efficiency, saving working time, and facilitating use.

[0031] See also Figure 1 and Figure 3The eight limiting plates 4 are grouped in pairs, and the positions of the four limiting plates 4 and the four mounting seats 11 correspond one to one. A ball groove 8 is provided on the side of each limiting plate 4 that contacts the packaging bag, and a ball 9 is rotatably connected inside the ball groove 8. A total of eight sections of threads are engraved on the outer end of the threaded rod 7, and the textures of the adjacent threads at the outer end of the threaded rod 7 are arranged opposite to each other. By arranging the textures of the adjacent threads at the outer end of the threaded rod 7 opposite to each other, when the threaded rod 7 is rotated, the threaded rod 7 can simultaneously adjust the distance between multiple groups of limiting plates 4 through the threaded connection formed with the slider 5 to adapt to agricultural and sideline products of different sizes.
