[0025] The present utility model will be further described below with reference to the accompanying drawings:

[0026] As Figures 1-8 shown, a pallet position correction device for a roller conveyor line includes a conveying mechanism 2 for conveying bagged materials. An elevating mechanism 1 for pushing it upward is provided on the conveying mechanism 2. A vibration platform 6 for vibrating and exhausting air from the bagged materials is provided below the conveying mechanism 2. It also includes two positioning mechanisms 3 for centering the pallet on which the bagged materials are placed. And two limiting plates 31 are respectively located on both sides of the conveying direction of the conveying mechanism 2. A thrust cylinder 4 for adjusting the pallet to be directly below the bagged materials is provided on one side of the positioning mechanism 3.

[0027] In this embodiment, the positioning mechanism 3 includes a limit plate 31, a positioning frame 32 is provided on the side of the limit plate 31 close to the tray, a plurality of rotating wheels 37 are provided inside the positioning frame 32 for facilitating the movement of the tray, a push plate 33 is fixed on the lower side of the positioning frame 32, and two push frames 34 are provided on the side of the push plate 33 away from the tray, and a fixing rod 35 is fixed at the lower end of the two push frames 34, and the two fixing rods 35 are respectively fixed on both sides of the vibration platform 6, and a return spring 36 is provided between the limit plate 31 and the two push frames 34. A slide groove is provided on the push plate 33 for facilitating the up and down sliding of the push frame 34, and the push frame 34 is a C-shaped structure, and a convex head for pushing the push plate 33 is provided on the upper end of the push frame 34, and an arc surface for the convex head of the push frame 34 to slide out is provided at the lower end of the slide groove of the push plate 33, and the lifting of the lifting mechanism 1 is used to drive the limit plate 31 to move. When the positioning plate 31, the positioning frame 32 and the pushing plate 33 move upward as a whole, the convex head at the upper end of the pushing frame 34 will slide out from the lower end of the sliding groove of the pushing plate 33, and at the same time, the pushing plate 33 will move the positioning frame 32 closer to the pallet under the action of the convex head and the arc surface. When the rotating wheels 37 on the positioning frame 32 are in contact with the two sides of the pallet, the pushing frame 34 completely slides out of the sliding groove of the pushing plate 33, and then the pallet is centered by the rotating wheels 37 on the two positioning frames 32. In addition, when the lifting mechanism 1 moves downward, the limiting plate 31, the positioning frame 32 and the pushing plate 33 move downward, and the convex head that slides out of the sliding groove will slide back into the sliding groove, and the reset spring 36 will drive the pushing plate 33 and the positioning frame 32 to move in the direction away from the pallet. At the same time, the limiting plate 31 will move synchronously along the notch, and then break away from the centering fixation of the pallet.

[0028] In this embodiment: the lifting mechanism 1 includes a frame 11, two connecting frames 12 are provided on the front and rear sides of the frame 11, and a hydraulic rod 13 is fixed at the lower end of the connecting frame 12 for driving it to lift and lower. A reset port 14 is opened in the middle position of the frame 11 for facilitating the up and down movement of the push frame 34, and a notch is provided at the upper end of the reset port 14 for facilitating the sliding of the limit plate 31. A fixed plate 5 supporting it is provided on the lower side of the push cylinder 4, and the two ends of the fixed plate 5 are fixed to the top of the frame 11. The telescopic part of the push cylinder 4 is provided with a push plate for pushing the pallet. The frame 11 is lowered through the four connecting frames 12 by retracting the telescopic parts of the four hydraulic rods 13, and then the pallet with the bagged material is placed on the vibration platform 6 for vibration exhaust. After the vibration is completed, the pallet is driven to move in the opposite direction by the conveying mechanism 2 so that one side of the outer side is attached to the push plate of the push cylinder 4. At the same time, the pallet is centered by the positioning mechanism 3 during lifting, and then the push plate is pushed by the telescopic part of the push cylinder 4 to move the pallet to the bottom of the bagged material after lifting.

[0029] In this embodiment: The conveying mechanism 2 includes conveying rollers 22. A plurality of conveying rollers 22 are rotatably connected to the inner side of the frame 11, and a first sprocket 23 is fixed to one end of each conveying roller 22 extending out of the frame 11. A chain 25 for driving their rotation is sleeved outside the plurality of first sprockets 23. A second sprocket 24 for supporting the chain 25 is provided between two adjacent first sprockets 23. A conveying motor 21 for driving the rotation of the conveying roller 22 is fixedly arranged at the input end of the conveying roller 22 located at one end of the frame 11. A sleeve hole is formed in the pushing plate 33 at the position of the return spring 36. The conveying roller 22 at the position of the return port 14 is located in the sleeve holes of the two pushing plates 33. One end of the return spring 36 away from the pushing plate 33 is fixed in the return port 14. The rotation part of the conveying motor 21 is used to drive the conveying roller 22 at its rear end to rotate. Then, the first sprocket 23 drives the chain 25 to rotate. At this time, under the support of the plurality of second sprockets 24 for the chain 25, the chain 25 drives the plurality of first sprockets 23 and the conveying rollers 22 on their front sides to rotate synchronously, and then the tray with the bagged material is conveyed.

[0030] Working principle: When in use, first place the tray on the conveying roller 22 on the frame 11. At this time, the conveying motor 21 drives the conveying roller 22 to rotate in the reverse direction. Then, the first sprocket 23 at the rear end of the conveying roller 22 drives the chain 25 to rotate. Then, under the support of the second sprocket 24 for the chain 25, the chain 25 drives the plurality of first sprockets 23 and the conveying rollers 22 on their front sides to rotate synchronously in the reverse direction, and then the tray on the conveying roller 22 is moved to directly below the material to be filled. Then, place the lower end of the bag that needs to be filled with the material on the tray, and then start filling the material into the bag;

[0031] When a certain amount of material is filled in the bag, the shrinkage of the telescopic parts of the four hydraulic rods 13 is used to lower the frame 11 through the four connecting frames 12. Then, the tray on the conveying roller 22 is placed on the vibrating platform 6, and the material in the bag on the tray is exhausted through the vibration of the vibrating platform 6. After the exhaust is completed, the bag is lifted from the tray to avoid contact with the tray. Then, the four hydraulic rods 13 push the entire frame 11 upward to lift the tray placed on the vibrating platform 6 by the conveying roller 22. At this time, the limiting plate 31, the positioning frame 32, and the pushing plate 33 move upward as a whole. Since the four pushing frames 34 are fixed to the vibrating platform 6 by the fixing rods 35, when the pushing plate 33 moves upward, the convex heads at the upper ends of the pushing frames 34 will slide out from the lower ends of the chutes of the pushing plate 33. When the convex heads slide out from the arc-shaped surfaces on the lower side of the chutes, they will push the positioning frame 32 to move closer to both sides of the tray through the pushing plate 33. When the rotating wheels 37 on the positioning frame 32 are in contact with both sides of the tray, the pushing frames 34 completely slide out of the chutes of the pushing plate 33. Then, the tray is centered and positioned by the rotating wheels 37 on the two positioning frames 32. At the same time, the conveying mechanism 2 drives the tray to move in the reverse direction so that one side of it is in contact with the push plate of the pushing cylinder 4. Then, the push plate is pushed by the telescopic part of the pushing cylinder 4 to move the tray directly below the lifted bagged material. Then, the lifted bagged material is placed back on the tray for filling;

[0032] During the entire filling process, it can be repeated multiple times to compact and exhaust the material in the bag, avoiding the occurrence of false filling;

[0033] In addition, when the lifting mechanism 1 moves downward, the limiting plate 31, the positioning frame 32, and the pushing plate 33 move downward. At this time, the convex heads that have slid out of the chutes will slide back into the chutes, and the reset spring 36 drives the pushing plate 33 and the positioning frame 32 to move away from the tray. At the same time, the limiting plate 31 will move synchronously along the notch and then disengage from the centering fixation of the tray.

[0034] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
