Description

Technical Field

[0001] The utility model relates to the technical field of steel processing feeding equipment, in particular to an auxiliary feeding device for steel ablation. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, the demand in the steel market has shown a rapid growth trend. In the process of ablation of steel raw materials, a feeding device is often required to transport the raw materials. A conveyor belt is needed in the feeding process, but the current conveyor belt is inconvenient to move, and the feeding angle cannot be adjusted, which greatly reduces the use range of the current conveyor belt. In addition, there will be a lot of dust and other garbage on the surface of the steel waste. During the transportation process on the conveyor belt surface, the dust and garbage on the surface will stick to the conveyor belt surface, which will cause the steel waste to slip during the transportation process on the conveyor belt surface, reducing the transportation efficiency and making it inconvenient for the staff to use.

[0003] The publication (announcement) number is CN209834721U, which discloses a steel scrap feeding conveyor belt, including a base, both ends of the outer wall on one side of the top of the base are connected to support columns by bolts, and both ends of the outer wall on the other side of the top of the base are hinged with a first hydraulic cylinder by hinges, the first hydraulic cylinder and the top outer wall of the support column are hinged with a first mounting plate by hinges, the outer walls of the top ends of the two first mounting plates are connected to connecting plates by bolts, and the two sides of the outer walls of the opposite ends of the two connecting plates are rotatably connected to rotating rollers through bearings, and the top outer wall of the connecting plate is connected to a protective plate by bolts. In the utility model, by providing a first hydraulic cylinder, the inclination angle of the conveyor belt can be changed according to the use requirements, the feeding requirements can be met, and the use range of the conveyor device is greatly improved. Then, when the staff puts the steel scrap on the conveyor belt, it prevents the steel scrap from being too heavy and damaging the conveyor belt, thereby improving the safety of use.

[0004] Although the above scheme can adjust the inclination angle of the conveyor belt and improve its safety, the steel raw materials on the conveyor belt lack guidance and control, and it is difficult for the equipment to flexibly control the feeding amount. The cleaning of the conveyor belt requires the cooperation of hydraulic cylinders and electric motors, and the operating cost of the equipment for the conveyor belt cleaning structure is high. For this reason, we propose an auxiliary feeding device for steel ablation. Utility Model Content

The bidirectional screw rod is movably arranged on the inner wall of one of the strip-shaped boxes. There are four support blocks in total and they are equally divided into two groups. One group of support blocks respectively cooperate with the symmetrically arranged positive and negative two sections of threads on the bidirectional screw rod. A number of the support arms are in an "L" shape and are fixedly arranged at the top of each support block one by one. At the top of every two support arms located on the same horizontal center plane in the transverse direction, a baffle plate in an "L" shape is fixedly arranged correspondingly, and the baffle plate is located above the top surface of the conveyor belt. The flared inclined plate and the converging inclined plate are respectively fixedly arranged at both ends of the baffle plate. One end of the bidirectional screw rod that extends movably outside the strip-shaped box is fixedly provided with a first turntable;

[0008] The cleaning unit includes a support frame, a sliding rod, a support plate, a longitudinal scraping plate and a support screw rod. An activity notch is opened at the center of the top surface of the carrier plate. The support frame is in a "U" shape and is fixedly arranged at the bottom surface of the carrier plate. The sliding rod is fixedly arranged on the concave surface at the bottom of the support frame and is located outside the activity notch. The support plate is in a "convex" shape and is movably sleeved on the outer peripheral surface of the sliding rod. The longitudinal scraping plate is fixedly arranged at the top of the support plate and is located directly below the bottom surface of the conveyor belt. The support screw rod is threadedly connected to the center of the bottom surface of the support frame and is located directly below the support plate. The bottom end of the support screw rod located below the support frame is fixedly provided with a second turntable.

[0009] Preferably, the material control unit further includes a guide rod. The guide rod is fixedly arranged on the inner wall of the other strip-shaped box and movably penetrates through the other group of support blocks. The flared inclined plate and the converging inclined plate are arranged in one-to-one correspondence with the baffle plate.

The top surface of the bottom plate is fixedly connected to the other end of the support vertical plate and the other end of the electric push rod. The hinged cross bar can cooperate with the carrier plate to rotate and tilt to adjust the inclination of the conveyor belt, and the electric push rod mainly cooperates with one end of the carrier plate to lift.

[0013] Preferably, feet are fixedly arranged at the corners of the bottom surface of the bottom plate.

[0014] Compared with the prior art, the auxiliary feeding device for steel ablation of the present utility model has the following beneficial effects:

[0015] 1. In the present utility model, by setting the material control unit, before the steel raw material is placed on the top surface of the conveyor belt, by holding the first turntable, the bidirectional lead screw can be controlled to rotate forward and backward on the strip box. Two of the supporting blocks threadedly connected to the bidirectional lead screw move relative to each other under the action of force, and can cooperate with the supporting arms in an "L" shape to drive two baffles in an "L" shape to adjust the spacing above the top surface of the conveyor belt. The other two supporting blocks can slide and translate on the guide rod to cooperate with the baffles to move and provide auxiliary support for them. The two groups of flaring inclined plates and converging inclined plates are adjusted synchronously. The steel raw material is conveyed and gathered from the two flaring inclined plates at the end faces of the two baffles, restricted by the two baffles, and then gathered and dropped out by the two converging inclined plates. By adjusting the spacing of the baffles, the width of the blanking channel can be controlled, and the final blanking amount can be controlled. The device can flexibly and simply control the feeding amount.

[0016] 2. In the present utility model, by setting the cleaning unit, by holding the second turntable, the support screw can be controlled to rotate and lift on the "U"-shaped support frame. The "convex"-shaped support plate is pushed by the top end of the support screw, which can help the longitudinal scraper to lift and adjust in the activity notch at the center of the top surface of the carrier plate. The slide rod fixedly arranged on the concave surface at the bottom of the support frame and located outside the activity notch can cooperate with the support plate to stably slide and lift. The longitudinal scraper then contacts the center of the bottom surface of the conveyor belt to clean the continuously conveyed surface of the conveyor belt. When dealing with the longitudinal scraper, reversing the support screw makes the longitudinal scraper drop below the carrier plate, which is convenient for maintenance. The cleaning structure of the conveyor belt of the device is simple and the operation cost is low. Description of the Drawings
