Description

Technical Field

[0001] The utility model relates to a device for conveying waste steel coils formed by side wires on both sides during the uncoiling and leveling process of steel coils, belonging to the technical field of waste steel coil conveying. Background Technique

[0002] Steel plates are usually formed by uncoiling steel coils produced by steel mills and then cutting them into certain width specifications through a slitting machine, which is called steel coil uncoiling, slitting and strip cutting. The side wires (narrow side strips) cut from both sides of the steel coil are wound and collected by a side wire machine to form waste steel coils, which are unloaded and recycled.

[0003] The existing unloading method of the side wire machine is to pack the waste steel coil on the side wire machine and then drop it to the ground. The dropping position is directly below the side wire machine, which is not convenient for hoisting. If it is not hoisted away in time, the protruding material head of the waste steel coil will affect the operation of personnel. Therefore, it is very laborious to hoist each waste steel coil; after the waste steel coil drops to the ground, a lifting belt needs to be threaded through it to lift it. During the process of threading the lifting belt, the protruding material head may pierce or cut the operator, which is very unsafe; after packing, it needs to be hoisted out obliquely. If not careful during the operation, the waste steel coil may swing in the air, possibly injuring the operator and equipment, making the operation inconvenient and unsafe, and wasting effective operation time.

[0004] For traditional chain plate conveyors, the processing cycle of the chain is long, the replacement is inconvenient, and the middle chain plate is easily deformed and damaged by impact, which is not suitable for the conveying working scenario of waste steel coils. Summary of the Invention

[0005] Aiming at the deficiencies existing in the existing waste steel coil conveying technology on the side wire machine, the utility model provides a waste steel coil conveyor with large bearing capacity, high efficiency, safety and reliability.

[0006] The waste steel coil conveyor of the utility model adopts the following technical solutions:

[0007] The system includes a frame, a reduction motor, a power transmission mechanism and a conveying mechanism. The reduction motor, the power transmission mechanism and the conveying mechanism are all arranged on the frame. The power transmission mechanism is connected to the reduction motor, and the conveying mechanism is connected to the power transmission mechanism.

[0008] The frame includes a bearing seat and legs, and the bearing seat is connected to the legs. The upper part of the bearing seat is an integral steel plate, and the lower part is a criss-cross reinforcing rib arranged on the bottom surface of the integral steel plate.

[0009] The power transmission mechanism includes a power driving sprocket, a power driven sprocket, a power shaft and a power chain. The power driving sprocket is installed on the rotating shaft of the reduction motor, the power driven sprocket is installed on the power shaft, the power shaft is installed on one side of the frame, and a power chain is connected between the power driving sprocket and the power driven sprocket. The reduction motor drives the power driving sprocket, the power chain, and drives the power driven sprocket and the power shaft to rotate.

[0010] A power chain adjustment mechanism is further provided between the reduction motor and the frame, which is used to adjust the position of the reduction motor so that the power chain is always in a tensioned state. The power chain adjustment mechanism adopts an existing bolt adjustment mechanism, and the reduction motor is moved by rotating the bolt installed on the frame.

[0011] The conveying mechanism includes a conveying driving sprocket, a conveying driven sprocket, a conveying shaft and a conveying chain. The conveying driving sprocket is installed on the power shaft in the power transmission mechanism, the conveying driven sprocket is installed on the conveying shaft, the conveying shaft is installed on the frame, the power shaft and the conveying shaft are respectively on both sides of the frame, and a conveying chain is connected between the conveying driving sprocket and the conveying driven sprocket. The conveying chain surrounds the bearing seat on the frame.

[0012] A conveying chain adjustment mechanism is provided between the conveying shaft and the frame, which is used to adjust the tightness of the conveying chain. An existing bolt adjustment mechanism is adopted, and the conveying shaft is moved by rotating the bolt installed on the frame to achieve the purpose of tensioning the conveying chain.

[0013] A waste bin is provided at the end of the frame (the outer side in the conveying direction) for receiving waste steel coils. The waste bin is composed of a base and a box body. The box body is open at the top and bottom. One side (fixed side) of the base is connected to the box body through a hinge shaft, and a plug-in pin shaft is connected between the other side (open side) and the box body to quickly open the base. A retaining pin hole is provided at one end of the plug-in pin shaft, and a retaining pin is inserted into the retaining pin hole to prevent the plug-in pin shaft from falling off by itself. A base rotation angle limit stop block is provided on the box body so that the box body can naturally fall onto the base when the base is placed on the ground.

[0014] The reduction motor drives the conveying mechanism to operate through the power transmission mechanism. The waste steel coil falls on the frame and is dragged and moved by the conveying mechanism. The upper surface of the frame bears the main impact of the waste steel coil. When it reaches the end of the frame, it directly falls into the waste bin without the need for personnel to intervene beside. After the waste bin filled with waste steel coils is lifted and transported to the placement position, the base of the waste bin is opened for unloading.

[0015] The utility model has low manufacturing cost, convenient maintenance, easy operation, can withstand large impacts, is safe and reliable. It can save effective operation time, improve production efficiency, reduce the disadvantages existing in hoisting, especially oblique hoisting, and protect the safety of operators and equipment.

[0020] The waste steel coil conveyor of the present utility model is used for conveying the waste steel coil unloaded from the edge wire machine, and its structure is as shown in Figure 1 and Figure 2 , and includes a frame 7, a reduction motor 1, a power transmission mechanism and a conveying mechanism. The reduction motor 1, the power transmission mechanism and the conveying mechanism are all arranged on the frame 7. The power transmission mechanism is connected to the reduction motor 1, and the conveying mechanism is connected to the power transmission mechanism.

[0021] The frame 7 includes a bearing seat 5 and legs 20. The bearing seat 5 is connected to a plurality of legs 20. The upper part of the bearing seat 5 is an integral steel plate, and the lower part is a criss-cross reinforcing rib arranged on the bottom surface of the integral steel plate. After the waste steel coil 9 is unloaded from the edge wire machine, it falls on the bearing seat 5. The integral steel plate on the upper part of the bearing seat 5 prevents the waste steel coil 9 from falling through the gap between the conveyor chains 8 of the conveying mechanism during transportation. The reinforcing rib arranged at the bottom of the integral steel plate enhances its strength, improves the impact force, and prevents the impact force when the waste steel coil 9 falls from deforming the steel plate on the upper surface, resulting in difficult transportation.

[0022] The power transmission mechanism adopts chain drive. Refer to Figure 1 and Figure 2 , and includes a power driving sprocket 11, a power driven sprocket 12, a power shaft 14 and a power chain 6. The power driving sprocket 11 is installed on the rotating shaft of the reduction motor 1, the power driven sprocket 12 is installed on the power shaft 14, the power shaft 14 is installed on the frame 7, and the power chain 6 is connected between the power driving sprocket 11 and the power driven sprocket 12. When the reduction motor 1 is started, its rotating shaft drives the power driving sprocket 11 to rotate, and then drives the power driven sprocket 12 and the power shaft 14 to rotate through the power chain 6. The power shaft 14 provides power for the conveying mechanism.

[0023] A power chain adjusting mechanism 4 is also provided between the reduction motor 1 and the frame 7, which is used to adjust the position of the reduction motor 1 so that the power chain 6 is always in a tensioned state, preventing the occurrence of tooth climbing; the power chain adjusting mechanism 4 adopts an existing bolt adjusting mechanism, and the reduction motor 1 is moved by rotating the bolt installed on the frame 7.

[0024] The conveying mechanism is a conveyor chain conveying method, see Figure 1 and Figure 2 , and includes a conveying driving sprocket 13, a conveying driven sprocket 16, a conveying shaft 15 and a conveying chain 8. The conveying driving sprocket 13 is installed on the power shaft 14, the conveying driven sprocket 16 is installed on the conveying shaft 15, the conveying shaft 15 is installed on the frame 7, and the power shaft 14 and the conveying shaft 15 are respectively on both sides of the conveying direction of the frame 7. The conveying chain 8 is connected between the conveying driving sprocket 13 and the conveying driven sprocket 16. In order to improve the conveying force and make the conveying stable, multiple groups of conveying chains 8 ( Figure 2 there are 3 groups set in ) are provided. Correspondingly, 3 conveying driving sprockets 13 are installed on the power shaft 14, and 3 conveying driven sprockets 16 are installed on the conveying shaft 15. The conveying chain 8 surrounds the bearing seat 5 of the frame 7 and is placed on the upper integral steel plate of the bearing seat 5.

[0025] A conveying chain adjusting mechanism 10 is provided between the conveying shaft 15 and the bearing seat 5 of the frame 7, which is used to adjust the tightness of the conveying chain 8. That is, it prevents the conveying chain 8 from being too loose and causing tooth climbing, and also prevents the conveying chain 8 from being too tight, so that the waste steel coil 9 will not damage the conveying chain 8 when it drops. The conveying chain adjusting mechanism 10 adopts an existing bolt adjusting mechanism, and the conveying shaft 15 is moved by rotating the bolt installed on the bearing seat 5 to achieve the purpose of tensioning the conveying chain 8.

[0026] A waste bin is provided at the end of the bearing seat 5 of the frame 7 (the outside of the conveying direction), which is used to receive the waste steel coil 9 conveyed from the bearing seat 5. See Figure 1 and Figure 2 , the waste bin is composed of a base 2 and a box body 3. The box body 3 is a frame structure with openings at the top and bottom. One side (fixed side) of the base 2 is connected to the box body 3 through a hinge shaft 17, and a plug-in pin shaft 18 is connected between the other side (open side) and the box body 3. The base 2 is quickly opened by plugging and unplugging; a retaining pin hole is provided at one end of the plug-in pin shaft 18, and a retaining pin 19 is inserted into the retaining pin hole, so that the plug-in pin shaft 18 will not fall off by itself, ensuring safety. The discharging state of the waste bin is as Figure 3As shown in the figure, when unloading the steel coil, pull out the retaining pin 19 on the open side, then pull out the plug-in pin shaft 18. Lift the box body 3, and the base 2 rotates open around the hinge shaft 17, and the waste steel coil 9 rolls out of the box body 3. A base rotation angle limiting device is also provided on the fixed side, which can be a limiting stop block provided on the box body. When the base 2 rotates downward around the hinge shaft 17 to open, the limiting stop block limits the rotation angle of the base 2 to be less than 90 degrees, ensuring that the box body 3 can naturally fall onto the base 2 when the base 2 is placed on the ground. After the box body 3 and the base 2 are combined, insert the plug-in pin shaft 18 on the open side, and then insert the retaining pin 19 on the plug-in pin shaft 18, so that the bottom of the box body 3 is blocked by the base 2, facilitating the re-loading of the steel coil.

[0027] The operation process of the above waste steel coil conveyor is as described below.

[0028] Start the reduction motor 1, and drive the power shaft 14 to rotate through the chain drive composed of the power driving sprocket 11, the power chain 6, and the power driven sprocket 12. The three groups of conveying driving sprockets 13 on the power shaft 14 rotate accordingly. The conveying driving sprocket 13 drives the conveying chain 8 to run between the conveying driving sprocket 13 and the conveying driven sprocket 16.

[0029] The waste steel coil 9 falls on the bearing seat 5 of the frame 7 and is dragged and moved by the conveying chain 8. The roller shaft in the conveying chain 8 contacts and rolls on the upper surface of the bearing seat 5, and the upper surface of the bearing seat 5 bears the main impact of the waste steel coil 9. When reaching the end of the bearing seat 5, it directly drops into the waste bin without the need for personnel to intervene beside, which is convenient to operate, time-saving and labor-saving. The waste bin can receive multiple waste steel coils 9, and can be centrally lifted and transported away when idle, without occupying the effective operation time, which is convenient for unloading. The two waste bins are used alternately, and the operation of the conveyor is not affected after one is lifted away.

[0030] After the waste bin filled with the waste steel coil 9 is lifted and transported to the placement position, open and unload it as shown in Figure 3 the figure.
