Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1 to 6This utility model provides a technical solution: a sealing machine for grain packaging, comprising a ring conveyor belt 1 and a U-shaped carrier 2. A support plate 3 is installed on the inner surface of the ring conveyor belt 1. A first electric push rod 4 is installed on the inner top wall of the support plate 3. A U-shaped plate 5 is installed on the movable end of the first electric push rod 4. A rectangular groove with the front-back direction as the depth direction and the left-right direction as the length direction is opened on the inner wall of the U-shaped plate 5. The end of the rectangular slider 13 is located inside the rectangular groove and the rectangular slider 13 can slide along the length direction of the rectangular groove. A second electric push rod 6 is installed on the inner top wall of the U-shaped plate 5. A lifting plate 7 is installed on the movable end of the second electric push rod 6. A positioning slider 8 is installed in front of the lifting plate 7. Fixing blocks 9 are installed on both sides of the U-shaped plate 5. One side of the fixing block 9 is connected by a shaft. A V-shaped rod 10 is rotatably connected, and a positioning groove is opened at the front of the V-shaped rod 10. The end of the positioning slider 8 is located inside the positioning groove, and the positioning slider 8 can slide along the length of the positioning groove. A mating rod 11 is rotatably connected to one side of the V-shaped rod 10 through a shaft. An adjusting block 12 is rotatably connected to one side of the mating rod 11 through a shaft. Rectangular sliders 13 are installed at the front and back of the adjusting block 12. A closing clamp 14 is installed at the bottom of the adjusting block 12. A hot melt machine 15 is installed on one side of the closing clamp 14. The position of the hot melt machine 15 corresponds to the position of the U-shaped carrier 2. The position of the hot melt machine 15 is higher than the position of the U-shaped carrier 2. The annular conveyor belt 1, the first electric push rod 4, the second electric push rod 6, and the hot melt machine 15 are all electrically connected to an external power source through wires.

[0028] In use, the grain-filled packaging bags are placed on the U-shaped carrier 2. The circular conveyor belt 1 transports the grain packaging bags. When the U-shaped carrier 2 transports the packaging bags to below the hot melt machine 15, the circular conveyor belt 1 stops rotating. The movable end of the first electric push rod 4 extends, positioning the closing clamp 14 on both sides of the packaging bag. Then, the movable end of the second electric push rod 6 retracts, causing the lifting plate 7 to move the positioning slider 8. The end of the positioning slider 8 is located inside the positioning groove. The movement of the positioning slider 8 causes the V-shaped rod 10 to rotate around the fixed block 9 and the rotating connection of the V-shaped rod 10. The movement of the V-shaped rod 10 causes the mating rod 11 and the adjusting rod 12 to rotate. The segment 12 moves, causing the rectangular slider 13 to slide along the length of the rectangular groove. This causes the adjusting block 12 to move the closing clamp 14 and the hot melt machine 15. When the hot melt machine 15 clamps the end of the packaging bag, it heats and melts the bag to close the end. Then, the movable end of the second electric push rod 6 extends, causing the positioning slider 8 to reset the V-shaped rod 10. This causes the adjusting block 12 to move the closing clamp 14 and the hot melt machine 15 away from the packaging bag. After that, the movable end of the first electric push rod 4 retracts, causing the hot melt machine 15 to rise and reset. Then, the circular conveyor belt 1 continues to transport grain, improving practicality.

[0029] Example 2

[0030] Please see Figures 1 to 5 This utility model provides a technical solution: a sealing machine for grain packaging, wherein a positioning block 16 is installed at the bottom of a U-shaped carrier 2, and a limiting groove with the left-right direction as the depth direction is opened on one side of the positioning block 16. The end of the limiting block 24 away from the threaded ring block 23 is inserted into the limiting groove. A cavity plate 17 is installed at the top of the annular conveyor belt 1. A T-shaped groove with the up-down direction as the depth direction and the left-right direction as the length direction is opened inside the cavity plate 17. The end of the T-shaped slider 25 is located inside the T-shaped groove and can slide along the length direction of the T-shaped groove. The top of the cavity plate 17 abuts against the bottom of the U-shaped carrier 2. The top of the cavity plate 17 has a limiting groove with the up-down direction as the depth direction. The positioning groove is provided, and the end of the positioning block 16 is inserted into the positioning groove. Inside the cavity plate 17, a round rod 18 and a double-acting screw 19 are rotatably connected via bearings. An adjusting disc 20 is installed at one end of the round rod 18, and the adjusting disc 20 is located outside the cavity plate 17. The driving bevel gear 21 is located inside the cavity plate 17 and meshes with the driven bevel gear 22 through its teeth. The driving bevel gear 21 is installed at the other end of the round rod 18, and the driven bevel gear 22 is installed at the end of the double-acting screw 19. A threaded ring block 23 is connected to the outer surface of the double-acting screw 19. A limit block 24 is installed on one side of the threaded ring block 23, and a T-shaped slider 25 is installed at the bottom of the threaded ring block 23.

[0031] When using the U-shaped carrier 2, rotate the adjusting disc 20 to make the round rod 18 drive the driving bevel gear 21 to rotate. The driving bevel gear 21 meshes with the driven bevel gear 22, which in turn drives the double-acting screw 19 to rotate. The double-acting screw 19 is connected to the threaded ring block 23, and the end of the T-shaped slider 25 is located inside the T-shaped groove. This causes the threaded ring block 23 to move the T-shaped slider 25 and the limiting block 24, making the limiting block 24 leave the limiting groove. Then, move the U-shaped carrier 2 upward to make the positioning block 16 leave the positioning groove, facilitating the movement of the U-shaped carrier. When disassembling and replacing U-shaped carrier 2, move U-shaped carrier 2 so that the end of positioning block 16 is inserted into the positioning groove. When the bottom of U-shaped carrier 2 abuts against the top of cavity plate 17, the limiting groove is aligned with the limiting block 24. Rotate adjustment disc 20 in the opposite direction so that driven bevel gear 22 drives bidirectional screw 19 to rotate in the opposite direction so that threaded ring block 23 drives limiting block 24 to reset. The end of limiting block 24 is inserted into the limiting groove, which facilitates limiting the position of positioning block 16, facilitates the installation of U-shaped carrier 2, and improves practicality.
