Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, specifically a bottom-rotating weighing and lifting feeding machine. Background Technology

[0002] A feeder is an automated conveying device widely used in industrial production. It is mainly used to transport raw materials or semi-finished products from one location to another, playing an important role in improving production efficiency and reducing labor costs.

[0003] Currently, existing feeding machines have a single feeding and positioning direction, which cannot flexibly adjust the material to the loading and unloading points, failing to meet the material weighing and handling needs between multiple workstations. Furthermore, their lifting and lowering of excessively heavy materials has the following drawbacks: 1. It causes severe overload damage to the electric equipment; 2. The single lifting structure cannot guarantee the stability of lifting and moving. Therefore, to address the above problems, a bottom-rotating weighing and lifting feeding machine is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a bottom-rotating weighing and lifting feeding machine to solve the above problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a bottom-rotating weighing and lifting feeding machine includes four weighing modules installed inside a U-shaped plate, a lifting traction frame, a lifting actuator, and an electric turntable. The weighing contact parts of the four weighing modules are respectively installed around the hopper. The back of the U-shaped plate is fixedly connected to the middle of one side of the lifting traction frame through a connecting frame. The four corners of the lifting traction frame are each set between two U-shaped steels through roller sets, and the top of the lifting traction frame is connected to the lifting actuator through a chain. The bottom ends of the two U-shaped steels are fixedly connected to the rotating part of the same electric turntable.

[0006] A further technical solution is provided, wherein the lifting actuator includes a first shaft, a first sprocket, a second sprocket, a hydraulic cylinder, and a second shaft. The first shaft is fixedly installed at the top between two U-shaped steels, and the first sprocket is rotatably installed on both sides of the middle of the first shaft. The middle of the second shaft is fixedly connected to the output end of the hydraulic cylinder, and the second sprocket is rotatably installed on both ends of the second shaft. The first sprocket and the second sprocket are respectively engaged with different parts on the same chain.

[0007] In a further technical solution, the bottom end of the cylinder body is fixedly installed at the rotating part of the electric turntable.

[0008] In a further technical solution, one end of the chain is fixedly connected to a connecting structure located between the tops of the two U-shaped steel sections.

[0009] A further technical solution is to provide a pneumatic gate at the bottom opening of the hopper.

[0010] In a further technical solution, the roller assembly consists of a first roller and a second roller, with the first roller and the second roller being vertically distributed vertically to each other, and the first roller and the second roller respectively rollingly contacting the side walls of different orientations inside the U-shaped steel.

[0011] Compared with the prior art, the advantages of this utility model are: The first sprocket at a high position is connected to a second sprocket that can be moved up and down by a hydraulic cylinder. Both the first and second sprockets are connected to a chain, which can form a pulley combination structure, reduce the lifting intensity, and meet the lifting requirements of heavy materials. First and second rollers, which are perpendicularly distributed to each other, are installed at the four corners of the lifting traction frame to achieve rolling contact with the side walls of the U-shaped steel in different directions, while improving the stability of the lifting traction frame when moving up and down between the two U-shaped steels.

[0018] Please see Figure 1-3 As shown, a bottom-rotating weighing and lifting feeding machine includes four weighing modules 2 installed in a U-shaped plate 3, a lifting traction frame 6, a lifting actuator, and an electric turntable 11. The weighing contact parts of the four weighing modules 2 are respectively installed around the loading hopper 1. The back of the U-shaped plate 3 is fixedly connected to the middle of one side of the lifting traction frame 6 through a connecting frame 5. The four corners of the lifting traction frame 6 are set between two U-shaped steels 9 through roller sets, and the top of the lifting traction frame 6 is connected to the lifting actuator through a chain 14. The bottom ends of the two U-shaped steels 9 are fixedly connected to the rotating part of the same electric turntable 11.

[0019] like Figure 2 As shown, the lifting actuator includes a first shaft 7, a first sprocket 8, a second sprocket 10, a hydraulic cylinder 12, and a second shaft 13. The first shaft 7 is fixedly installed at the top between two U-shaped steels 9, and the first sprocket 8 is rotatably installed on both sides of the middle of the first shaft 7. The middle of the second shaft 13 is fixedly connected to the output end of the hydraulic cylinder 12, and the second sprocket 10 is rotatably installed on both ends of the second shaft 13. The first sprocket 8 and the second sprocket 10 are respectively meshed with different parts on the same chain 14. The bottom end of the cylinder body of the hydraulic cylinder 12 is fixedly installed at the rotating part of the electric turntable 11.

[0020] One end of the chain 14 is fixedly connected to the connecting structure located between the top ends of the two U-shaped steels 9.

[0021] The bottom opening of the hopper 1 is equipped with a pneumatic door 4.

[0022] like Figure 2 As shown, the roller assembly consists of a first roller 610 and a second roller 620, and the first roller 610 and the second roller 620 are vertically distributed between each other. The first roller 610 and the second roller 620 respectively roll into contact with the side walls of different orientations inside the U-shaped steel 9, thereby improving the stability of the lifting traction frame 6 moving up and down between the two U-shaped steels 9.

[0023] Specific operation mode: The material in hopper 1 is weighed by distributed weighing modules 2. After weighing is completed, two actions are completed simultaneously, as follows: The first action: the cylinder 12, which was originally in the extended state, turns into the retracted state, causing the second shaft 13 and the second sprocket 10 connected to it to move down, which pulls down the chain 14 part at the second sprocket 10. At the same time, the first shaft 7, which is positioned in place, causes the first sprocket 8, which is driven to rotate by the chain 14, to rotate in place. Meanwhile, the lifting traction frame 6, which is connected to the chain 14, moves up along the space between the two U-shaped steels 9, and finally causes the loading hopper 1, which is connected to the lifting traction frame 6, the connecting frame 5, the U-shaped plate 3 and the weighing module 2, to move up. The second action: the electric turntable 11 drives the two U-shaped steels 9 and the hydraulic cylinder 12 to rotate, so that the loading hopper 1 is accurately positioned at the required position during the lifting process; When the hopper 1 is in place, the pneumatic door 4 at the hopper opening is opened, allowing the hopper opening at the bottom of the hopper 1 to allow the material to fall and complete the unloading operation.

[0024] Compared with the prior art, the advantages of this utility model are: 1. The first sprocket 8 at the high position is connected to the second sprocket 10, which can be pushed up and down by the hydraulic cylinder 12. At the same time, the first sprocket 8 and the second sprocket 10 are both connected to the chain 14, which can form a pulley combination structure, reduce the lifting intensity, and meet the lifting requirements of heavy materials. 2. First rollers 610 and second rollers 620 are installed at the four corners of the lifting traction frame 6 in a perpendicular manner to each other, so as to achieve the effect of rolling contact with the side walls of different directions inside the U-shaped steel 9, and at the same time improve the stability of the lifting traction frame 6 moving up and down between the two U-shaped steels 9.
