Description

Technical Field

[0001] This utility model relates to the field of calcium powder processing technology, and in particular to a calcium powder transfer clamp. Background Technology

[0002] Calcium powder is packaged in woven bags with an inner lining for moisture protection. Currently, automated packaging using mechanical equipment is common to improve automation. After filling and sealing, the packaging is transferred to a six-axis robot via a conveyor belt, where the robot stacks it onto pallets. During this transfer, the non-flat nature of the woven bags affects the stability and safety of the stacked product. Current methods use a dedicated flattening device above the conveyor belt to flatten the bags. However, this requires pausing the conveyor, impacting efficiency, and also increases equipment costs. Utility Model Content

[0003] This invention provides a calcium powder transfer clamp to overcome the shortcomings of the prior art. It facilitates the flattening of bagged calcium powder during transfer and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted:

[0005] A calcium powder transfer clamp includes a lower plate, on which clamping guide holes are symmetrically formed in pairs and arranged in parallel. Flattening guide holes are also symmetrically formed in pairs on the lower plate and arranged in parallel. The clamping guide holes are located outside the flattening guide holes.

[0006] A clamping link is movably installed inside the clamping guide hole. The upper end of the clamping link is connected to an upper moving plate by a thread. The lower end of the clamping link on the same side is connected to a lower plate strip by a thread. A clamping side plate is welded on the lower plate strip. The lower end of the clamping side plate is bent inward to form a lower clamping plate.

[0007] A flattening connecting rod is movably installed inside the flattening guide hole. The upper end of the flattening connecting rod on the same side is connected to an upper plate strip by a thread, and the lower end of the flattening connecting rod on the same side is connected to a concave frame by a thread. A flattening roller is rotatably installed at the lower end of the concave frame.

[0008] Furthermore, the inner end of the lower clamp has a wedge-shaped structure.

[0009] Furthermore, multiple upper extension rods are welded to the lower plate, and an upper plate is welded to the upper end of each upper extension rod. A hydraulic cylinder is bolted to the upper plate, and a movable plate is fixed to the movable end of the hydraulic cylinder. Multiple guide rods are threaded through the movable plate, with the lower end of the guide rods welded to the lower plate and the upper end of the guide rods welded to the upper plate. A movable side plate is welded to the inner end of the upper movable plate. An oblique hole is opened at the upper end of the movable side plate, with the upper end of the oblique hole extending inward at an incline. A vertical hole is opened at the lower end of the oblique hole. A lower connecting plate is welded between the lower ends of the movable side plates on the same side. Two pairs of lower extension arms are welded to the lower wall of the movable plate. Each pair of lower extension arms on the same side has a pressure rod rotatably mounted at the lower end. The pressure rod moves within the oblique hole and the vertical hole. The movable plate moves between each pair of movable side plates, and the lower extension arms are located inside the movable side plates.

[0010] Furthermore, an end rack is welded perpendicular to the length direction of one end of the upper plate, one end rack is located at one end of the lower plate, and the other end rack is located at the other end of the lower plate. A gear meshes on the end rack, and a rotating shaft is coaxially mounted on the gear. Several bearing seats are mounted on the rotating shaft, and the bearing seats are mounted on the lower plate by screws. A drive gear is coaxially mounted on the other end of the rotating shaft, and the drive gear meshes with a vertical rack. The vertical rack is mounted on the movable plate by screws, and the toothed sides of the vertical rack are arranged opposite each other.

[0011] The advantages of the above technical solution are:

[0012] This invention uses a pair of lower clamps to conveniently limit the lower side of the bagged calcium powder, while two flattening rollers limit the upper side of the bagged calcium powder, thus ensuring safety during transfer and stacking.

[0013] When the clamping action is performed, the present invention can also cause the flattening roller to act on the upper side of the bagged calcium powder, thereby flattening it and ensuring the safety and stability of the bagged calcium powder after stacking.

[0014] This invention enables the clamping and flattening of bagged calcium powder using a single hydraulic cylinder, thereby improving energy efficiency and reducing energy consumption. Attached Figure Description

The lower end of the clamping link 16 on the same side is connected to a lower plate strip 18 by a thread. A clamping side plate 19 is welded onto the lower plate strip 18. The lower end of the clamping side plate 19 is bent inward to form a lower clamping plate 20. The inner end of the lower clamping plate 20 has a wedge-shaped structure.

[0021] A flattening connecting rod 29 is movably provided inside the flattening guide hole 15. The upper end of the flattening connecting rod 29 on the same side is connected to an upper plate strip 28 by a thread, and the lower end of the flattening connecting rod 29 on the same side is connected to a concave frame 30 by a thread. A flattening roller 31 is rotatably provided at the lower end of the concave frame 30.

[0022] Multiple upper extension rods 10 are welded to the lower plate 1. An upper plate 11 is welded to the upper end of each upper extension rod 10. A hydraulic cylinder 12 is bolted to the upper plate 11. A movable plate 27 is fixed to the movable end of the hydraulic cylinder 12. Multiple guide rods 13 are threaded through the movable plate 27. The lower end of each guide rod 13 is welded to the lower plate 1, and the upper end of each guide rod 13 is welded to the upper plate 11. A movable side plate 21 is welded to the inner end of the upper movable plate 17. An oblique hole 23 is formed at the upper end of the movable side plate 21. The upper end of the plate extends inward at an inward angle, and the lower end of the inclined hole 23 is provided with a vertical hole 24. A lower connecting plate 22 is welded between the lower ends of the movable side plates 21 located on the same side. Two pairs of lower extension arms 26 are welded to the lower wall of the movable plate 27. Each pair of lower extension arms 26 located on the same side has a pressure rod 25 rotatably mounted at the lower end. The pressure rod 25 moves within the inclined hole 23 and the vertical hole 24. The movable plate 27 moves between each pair of movable side plates 21, and the lower extension arms 26 are located inside the movable side plates 21.

[0023] One end of the upper plate 28 is welded with an end rack 32 perpendicular to its length direction. One end rack 32 is located at one end of the lower plate 1, and the other end rack 32 is located at the other end of the lower plate 1. A gear 33 meshes on the end rack 32. A rotating shaft 34 is coaxially mounted on the gear 33. Several bearing seats 35 are mounted on the rotating shaft 34. The bearing seats 35 are mounted on the lower plate 1 by screws.

The vertical rack 37 is mounted on the movable plate 27 by screws, and the toothed sides of the vertical rack 37 are arranged opposite each other.

[0024] In this embodiment, the upper plate 11 is installed and fixed on the movable end of the six-axis robot, which is a common industrial handling robot.

[0025] When transferring bagged calcium powder, the six-axis robot moves it to the location to be transferred. Then, the six-axis robot moves the gripper downward and positions the lower clamp 20 on both sides of the bagged calcium powder. At this time, the bagged material is laid flat, and the length direction of the bagged calcium powder is parallel to the length direction of the lower clamp 20.

[0026] Then, the hydraulic cylinder 12 is activated, and the movable plate 27 moves downward under the drive of the hydraulic cylinder 12. During the movement, the pressure rod 25 moves downward from the upper end of the inclined hole 23. During the movement, the movable side plate 21 and the lower clamping plate 20 move inward along the length direction of the clamping guide hole 14, so that the lower clamping plate 20 is the lower side of the bagged calcium powder, until the clamping connecting rod 16 moves to the inner end of the clamping guide hole 14. At this time, the pressure rod 25 will also move from the inclined hole 23 to the upper end of the vertical hole 24, and the vertical rack 37 and the drive gear 33 mesh. When the pressure rod 25 moves in the vertical hole 24, the vertical rack 37 will act on the drive gear 33, so that the rotating shaft 34 and the gear 33 will rotate. When the gear 33 rotates, it will drive the upper plate 28 and the flattening roller 31 to move outward, and make the flattening roller 31 flatten the bagged calcium powder. Then, the six-axis robot stacks the bagged calcium powder on the pallet.
