Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for automotive sleeve processing, and in particular to a rotatable feeding device for an automotive sleeve heat treatment furnace. Background Technology

[0002] When producing automotive sleeves, our company needs to place the sleeves into a heat treatment furnace for heat treatment. The patent application number "202222354163.2" entitled "A Tilting Feeding Device for Automotive Sleeve Production" uses a hydraulic cylinder to drive the tilting box to rotate. After the tilting box rotates 90 degrees, the automotive sleeves are added to the inlet of the furnace.

[0003] Several problems exist with this device: 1) The tilting box is located on one side of the conveyor belt of the working furnace. When the tilting box tilts to unload material, the conveyor belt is relatively narrow, only about 30cm-40cm wide. Although baffles are provided, it is still easy for the truck sleeve to fall onto the outside of the conveyor belt, requiring manual removal onto the inside of the conveyor belt. 2) The hoisting rope of the winch is directly tied to the top of the tilting box. The point and direction of the force remain unchanged. This means that when the winch of the small gantry crane drives the tilting box to tilt, the winch itself also has to slide left and right along the gantry crane frame, increasing the complexity of operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a rotatable feeding device for a car sleeve heat treatment furnace. When the winch of the gantry crane is used to turn the tilting box, the winch only needs to wind up the wire rope and does not need to slide left or right. At the same time, the tilting box is arranged at the end of the conveyor belt and the structure of the tilting box is improved so that the car sleeve falls into the conveyor belt and does not fall outside the conveyor belt.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A rotatable feeding device for an automotive sleeve heat treatment furnace includes a tilting box. The lower front end of the tilting box is fixed to a rotating shaft via a connecting rod. The rotating shaft is rotatably mounted on a bracket. Arc-shaped guide rails are fixed on the left and right outer sides of the tilting box. Hanging rings are fixed on the tilting box within the inner ring of the guide rails. One end of a lifting rope is connected to the hanging rings. The lifting rope passes around the lower end of the guide rails and is connected to a winch above.

[0006] A horizontally positioned limiting groove is fixed to the outer side of the upper end of the guide rail. During the process of the tilting box being horizontal or tilted 90 degrees, the lifting rope always passes through the limiting groove and is in contact with the guide rail.

[0007] The limiting groove plate is U-shaped, and the horizontal length of the limiting groove plate is consistent with the radius of the guide rail.

[0008] The guide rail is an arc-shaped plate with welded reinforcing ribs on the inner side and both ends of the guide rail folded inward.

[0009] The tilting box includes left and right vertical side plates. A first connecting plate, a second connecting plate, and a third connecting plate are fixed between the two vertical side plates in sequence. The first connecting plate is located at one end of the two vertical side plates and is vertical. The second connecting plate and the third connecting plate are inclined in sequence to form a slope. The front end of the third connecting plate is vertically fixed with baffles on the left and right. The outer ends of the baffles are close together and form a discharge port with the third connecting plate. The width of the discharge port matches the width of the conveyor belt.

[0010] The second connecting plate forms a first angle with the horizontal plane, and the third connecting plate forms a second angle with the horizontal plane. The first angle is greater than the second angle.

[0011] The second connecting plate is provided with a filter groove, and a support plate is fixed between the two vertical side plates below the second connecting plate. The support plate, the second connecting plate, and the two vertical side plates form a dust collection area, and the dust collection area has a built-in storage hopper.

[0012] This utility model provides a rotatable feeding device for an automotive sleeve heat treatment furnace, which has the following technical advantages: 1) By installing the tilting box at the input end of the conveyor belt (instead of one side) and setting baffles at the discharge port of the tilting box in a V-shape, the discharge port of the tilting box is narrowed and matched with the width of the conveyor belt. This way, the material will not be poured into other places outside the conveyor belt when it is poured, avoiding cleaning.

[0013] 2) By setting guide rails, hanging rings and limiting grooves on the left and right sides of the tilting box, the point of action, the point of force and the direction of force of the hoisting rope on the tilting box can be changed. In this way, there is no need to move the position of the winch. The tilting box can be tilted simply by winding the wire rope of the winch, making the adjustment more convenient.

[0023] like Figure 1-4 As shown, a rotatable feeding device for an automotive sleeve heat treatment furnace includes a tilting box 1. The lower front end of the tilting box 1 is fixed to a rotating shaft 3 via a connecting rod 2. The rotating shaft 3 is rotatably mounted on a bracket 4. Arc-shaped guide rails 5 are fixed on the left and right outer sides of the tilting box 1. Hanging rings 6 are welded to the inner ring of the tilting box 1 on the guide rails 5. A horizontally arranged limiting groove plate 7 is fixed on the outer upper end of the guide rail 5. The limiting groove plate 7 is U-shaped and mainly limits the lifting rope 8, so that the lifting rope 8 always acts on the guide rail 5 when the tilting box 1 rotates. One end of the lifting rope 8 is hung on the hanging ring 6 via a hook. The lower end of the lifting rope 8 passes over the lower end of the guide rail 5, passes through the limiting groove 7, and connects to a crossbeam 9. The lifting ropes 8 located on the left and right sides of the tilting box 1 are correspondingly connected to the two ends of the crossbeam 9. The upper middle part of the crossbeam 9 is connected to the hook of the lifting rope 8 of the winch 10 of a movable gantry crane.

[0024] like Figure 5 As shown, the tilting box 1 includes left and right vertical side plates 1.1. A first connecting plate 1.2, a second connecting plate 1.3, and a third connecting plate 1.4 are fixed between the two vertical side plates 1.1. The first connecting plate 1.2 is located at the rightmost end of the two vertical side plates 1.1, and is vertically arranged and perpendicular to the two vertical side plates 1.1. One end of the second connecting plate 1.3 is sealed to the lower end of the first connecting plate 1.2, and the other end is inclined downwards. One end of the third connecting plate 1.4 is sealed to the lower end of the second connecting plate 1.3, and the other end is inclined downwards. Baffles 1.5 are fixed on the left and right sides of the third connecting plate 1.4. One side of the baffles 1.5 is connected to the leftmost end of the two vertical side plates 1.1. The baffles 1.5 are distributed in a V-shape, with the end of the baffles 1.5 close together near the discharge port and the end of the baffles 1.5 open near the two vertical side plates 1.1.

[0025] like Figure 7As shown, when the tilting box 1 lands, the first connecting plate 1.2 is in horizontal contact with the ground, and the car sleeve or the mesh frame with the car sleeve can be placed directly on the first connecting plate 1.2. In this way, when the tilting box 1 tilts, the car sleeve or the mesh frame with the car sleeve can be tilted together.

[0026] After the tilting box 1 is tilted 90 degrees, it forms the following shape: Figure 6 As shown, due to the inclination of the first connecting plate 1.2 and the second connecting plate 1.3, a ramp can be formed to allow part of the car sleeve to be removed.

[0027] like Figure 5 , Figure 8 As shown, preferably, the second connecting plate 1.3 is provided with multiple sets of filter grooves 1.6, which can filter dust and fine impurities in the car sleeve. A support plate 1.8 is fixed between the two vertical side plates 1.1 below the corresponding second connecting plate 1.3. The support plate 1.8, the second connecting plate 1.3, and the two vertical side plates 1.1 form a dust collection area. A collection hopper 1.7 is built into the dust collection area, and the end of the collection hopper 1.7 is magnetically attached to the end faces of the two vertical side plates 1.1. Dust from the car sleeve can enter the dust collection area through the filter grooves 1.6 and be collected by the collection hopper 1.7. The collection hopper 1.7 can be removed later for unified cleaning.

[0028] Working principle and process: 1) such as Figure 3 , Figure 7 As shown, in the initial state, the tilting box 1 is placed on the ground, and the wire mesh frame containing the car sleeves is placed inside the tilting box 1, or the car sleeves are placed directly inside the tilting box 1. When placing the car sleeves directly inside the tilting box 1, the number of car sleeves depends on the actual situation, ensuring that they do not slip out. 2) For example Figure 1 , Figure 6 As shown, the winch 10 then slowly winds up the wire rope, causing the tilting box 1 to tilt. After tilting, since the second connecting plate 1.3 and the third connecting plate 1.4 are both inclined surfaces, the car sleeve (cylindrical) rolls onto the conveyor belt through the second connecting plate 1.3 and the third connecting plate 1.4 and is carried away by the conveyor belt.

[0029] 3) After unloading the material, the winch 10 slowly releases the wire rope. Since the center of gravity of the tilting box 1 is on the right side of the shaft 3, under the action of gravity, the tilting box 1 tilts to the right and gently lands. It can be tilted again when unloading material again.
