Description

Technical Field

[0001] This application relates to the field of stepped lifting devices, and more particularly to a stepped lifting and feeding device for steel bars. Background Technology

[0002] Steel bars are materials made from stainless steel ingots through hot rolling or forging. They are commonly used in construction, machinery and industrial equipment. In industry, lifting and feeding devices are often used to transport steel bars.

[0003] Currently, Chinese utility model patent CN216686292U discloses a hoist for uniformly conveying tubular components, including a hopper, a hoisting component, and a conveying component. A baffle plate is provided at the connection between the hopper and the hoisting component. The conveying component includes a conveyor belt located at the discharge end of the hoisting component, a blow-off component located on the side of the conveyor belt away from the hoisting component, and a recovery chute located parallel to and connected to the hopper. The blow-off component and the recovery chute are arranged opposite each other on both sides of the conveyor belt. The technical effects are: by setting up the baffle plate, the blow-off component, and the recovery chute, the baffle plate prevents a large number of tubular components from entering the hoisting component, the blow-off component screens the tubular components hoisted to the conveyor belt, keeping the tubular components on the conveyor belt at a suitable distance, which is convenient for subsequent processes; the recovery chute is located on the other side of the conveyor belt, allowing the tubular components blown off the conveyor belt to slide back to the hopper.

[0004] When non-conforming steel bars move from the conveying assembly into the recycling chute, the steel bars will roll to the lowest point of the recycling chute. The recycling chute is located on one side of the hopper, and the steel bars are easily stuck at the connection between the recycling chute and the hopper, which can easily lead to the accumulation of non-conforming steel bars in the recycling chute, resulting in a long retention time of steel bars in the recycling chute. Utility Model Content

[0005] In order to reduce the accumulation of steel bars at the lowest point of the recycling chute and reduce the retention time of steel bars in the recycling chute, thereby improving the efficiency of steel bar circulation, this application provides a stepped lifting and feeding device for steel bars.

[0006] This application provides a stepped lifting and feeding device for steel bars, which adopts the following technical solution:

[0007] A stepped lifting and feeding device for steel bars includes a lifting machine body, a transport component, a recovery component, and a detection component. The transport component is disposed on the lifting machine body. The recovery component includes a recovery chute, a recovery drive belt, and a recovery motor. The recovery chute is located on one side of the lifting machine body, with one end of the recovery chute disposed on the transport component. The height of the recovery chute gradually decreases in the direction away from the transport component. The length direction of the recovery drive belt is parallel to the direction from the lifting machine body to the recovery chute. The height of the recovery drive belt is lower than the lowest point of the recovery chute. The recovery motor is used to drive the recovery drive belt to rotate. The detection component is used to guide steel bars that do not meet the requirements into the recovery chute.

[0008] By adopting the above technical solution, the steel bars are placed inside the lifting machine body. The lifting machine body transports the steel bars to the transport component. When the condition of the steel bars on the transport component does not meet the requirements, the detection component guides the steel bars into the recovery chute. The steel bars in the recovery chute roll onto the recovery conveyor belt. The recovery motor drives the recovery conveyor belt to rotate, and the steel bars re-enter the lifting machine body under the action of the recovery conveyor belt. Through the recovery transmission, the steel bars can be moved from the lowest point of the recovery chute to the lifting machine body, reducing the accumulation of steel bars and the retention time of steel bars in the recovery chute, thereby improving the efficiency of steel bar circulation.

[0009] Optionally, a deflector plate is provided on the outer wall of the recycling conveyor belt.

[0010] By adopting the above technical solution, the contact area between the steel bar and the recovery conveyor belt is small. By adding a baffle, the steel bar on the recovery conveyor belt can be better transported into the lifting machine body.

[0011] Optionally, the detection component includes an arc-shaped plate and an adjusting component. The arc-shaped plate is slidably connected to the transport component in a vertical direction. The arc-shaped plate is used to guide steel bars that do not meet the requirements into the recycling chute. The adjusting component is used to drive the arc-shaped plate to move.

[0012] By adopting the above technical solution, when the state of the steel bar on the transport component does not meet the requirements, the steel bar will abut against the arc surface of the arc plate. Guided by the arc surface, the steel bar will enter the recovery slide and return to the lifting machine body through the recovery transmission belt. There are various types of steel bars with different diameters. The distance between the arc plate and the transport component can be adjusted by the adjustment component, thereby enabling the detection of steel bars with different diameters and improving the applicability of the equipment.

[0013] Optionally, the adjusting component includes an adjusting motor and an adjusting screw. The length direction of the adjusting screw is parallel to the sliding direction of the arc-shaped plate. The adjusting screw is rotatably connected to the transport assembly. The arc-shaped plate is threadedly connected to the adjusting screw. The adjusting motor is used to drive the adjusting screw to rotate.

[0014] By adopting the above technical solution, when the position of the arc plate needs to be adjusted, the staff can start the adjustment motor, which drives the adjustment screw to rotate, and the adjustment screw drives the arc plate to move. The distance between the arc plate and the recycling conveyor belt changes, making it suitable for steel bars of different diameters.

[0015] Optionally, a plurality of rollers are provided on the arc-shaped surface of the arc plate, and the rollers are used to abut against steel bars whose condition does not meet the requirements.

[0016] By adopting the above technical solution, the rollers on the arc surface improve the guiding effect of the non-compliant steel bars and reduce the friction between the steel bars and the arc plate.

[0017] Optionally, the transport assembly includes a transport frame, a transport belt, two drive rollers, and a transport motor. The transport frame is mounted on the lifting machine body, the two drive rollers are distributed horizontally, the drive rollers are rotatably connected to the transport frame, the transport belt is sleeved on the drive rollers, and the transport motor is used to drive the drive rollers to rotate.

[0018] By adopting the above technical solution, after the lifting machine body transports the steel bar onto the transport belt, the transport motor drives the transmission roller to rotate, the transmission roller drives the transport belt to move, and the transport belt will drive the steel bar to move away from the lifting machine body. The transport component has a simple structure and is easy for workers to operate.

[0019] Optionally, the diameters at both ends of the drive roller are larger than the diameter in the middle of the drive roller.

[0020] By adopting the above technical solution, the shape of the transmission roller determines the shape of the transport belt, achieving a concave state of the transport belt and reducing the occurrence of steel bars detaching from the transport belt during transportation.

[0021] Optionally, the transport assembly further includes an ejector, which includes an ejector plate, an ejector cylinder, an ejector slide, and a baffle plate. The baffle plate is disposed on the transport frame and restricts the steel bar from detaching from the transport conveyor belt. The ejector slide is disposed on the transport frame and its height gradually decreases in the direction away from the transport frame. The ejector plate is slidably connected to the transport frame along the direction from the transport conveyor belt to the ejector slide. The ejector cylinder is used to drive the ejector plate to move.

[0022] By adopting the above technical solution, when the steel bar that meets the requirements moves to the required position on the conveyor belt, the steel bar is blocked by the blocking plate. At this time, the ejector cylinder drives the ejector plate to move, and the steel bar is pushed into the ejector slide. The steel bar moves to the next station through the ejector slide. The ejector has a simple structure and is easy to operate.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. A recovery conveyor belt is connected to the lowest point of the recovery chute, which facilitates the transport of steel bars in the recovery chute to the lifting machine body, reduces the retention time of steel bars in the recovery chute, and increases the turnover speed of steel bars in the lifting machine body.

[0025] 2. The adjusting mechanism can change the distance between the arc plate and the recycling conveyor belt, allowing the equipment to adapt to steel bars of different diameters;

[0026] 3. The ejector is used to detach the steel bar from the transport assembly. Attached Figure Description
