Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a manual precision belt material alignment and correction device for powder and small particle materials. Background Technology

[0002] In industrial production, belt conveyors are widely used for material transportation in industries such as mining, ports, construction, metallurgy, and power due to their advantages of simple structure, high conveying capacity, and strong adaptability. However, during long-term operation, belt conveyors often experience belt misalignment, where the belt deviates from the intended centerline and shifts to one side. Misalignment not only leads to material spillage and reduced conveying efficiency but also accelerates wear on the belt edges, and can even cause belt tearing, damage to idlers and rollers, increasing maintenance costs and posing production safety hazards.

[0003] In most cases, belt misalignment is caused by the material falling off the belt at an incorrect point. This situation is usually difficult to adjust. Forcibly correcting the belt misalignment with a guide roller will not only accelerate the wear of the guide roller, but also easily scratch the belt. This situation occurs frequently and causes great economic losses.

[0004] Therefore, designing a belt misalignment device with fast dynamic response and precise adjustment has become an important research direction for improving production efficiency and reducing downtime losses. Utility Model Content

[0005] This invention provides a manual precision belt alignment and correction device for powder and small particle materials, which solves the problems of existing forced alignment using alignment rollers, which accelerates wear on the rollers and easily scratches the belt.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A manual precision belt conveyor for adjusting and correcting powder and small particle materials includes:

[0008] The frame is fixed to the belt conveyor frame and located in front of the material drop point;

[0009] The lead screw is vertically installed on the frame, and a handwheel is connected to its top;

[0010] The feeding plate is horizontally set at the bottom of the lead screw and is linked with the lead screw through a threaded engagement to achieve vertical lifting and lowering to adjust the depth of insertion into the material layer;

[0011] The lever is hinged to the side of the frame, and its end is connected to the side of the material guide plate. The horizontal deflection angle of the material guide plate can be changed by moving it left and right.

[0012] Furthermore, the deflection angle adjustment mechanism of the material feeding plate includes a positioning hole with a positioning pin. This positioning hole with a positioning pin passes through the arc-shaped positioning hole plate between the lever and the side wall of the frame. By changing the angle of the lever, the positioning hole with a positioning pin fixes the deflection angle of the material feeding plate.

[0013] Furthermore, the surface of the feeding plate is bent into a guide surface in the direction of material flow.

[0014] Furthermore, the feed plate is made of stainless steel, and the distance between its lower edge and the surface of the belt is set to 5~10cm.

[0015] Furthermore, the bottom of the frame is provided with an adjustable mounting bracket, which includes a horizontal slide rail and locking screws.

[0016] Furthermore, the lead screw is covered with a dustproof sleeve, the inner wall of the sleeve is filled with lubricating grease, and a limit block is provided at the end of the lead screw's lifting stroke.

[0017] The beneficial effects of this utility model are as follows:

[0018] It can quickly, effectively, and accurately adjust the position of the belt, bringing it back to the correct operating track.

[0019] It has high stability and reliability and can adapt to the working environment.

[0020] It requires little investment, is simple and convenient to operate, safe, and easy to maintain. Attached Figure Description

[0030] This utility model provides a technical solution: a manual precision belt conveyor for adjusting and correcting the alignment of powder and small particle materials, such as... Figure 1-3 As shown, it includes:

[0031] The frame 1 is fixed to the belt conveyor frame 6 and is located in front of the material 7 drop point;

[0032] The lead screw 2 is vertically installed on the frame 1, and a handwheel 3 is connected to its top;

[0033] The material feeding plate 4 is horizontally positioned at the bottom of the lead screw 2 and is linked to the lead screw 2 via a threaded connection to achieve vertical lifting and lowering to adjust the depth of insertion into the material layer. The deflection angle adjustment mechanism of the material feeding plate 4 includes an angle locking positioning pin and a positioning hole with a positioning pin 10. The positioning hole with the positioning pin 10 passes through the handle 5 and the arc-shaped positioning hole plate 9 on the side wall of the frame 1. The deflection angle of the material feeding plate 4 is fixed by changing the angle of the handle 5 and then by the positioning hole with the positioning pin 10. The plate surface of the material feeding plate 4 is bent into a guide surface in the direction of material flow 7.

[0034] The lever 5 is hinged to the side of the frame 1, and its end is connected to the side of the material guide plate 4. The horizontal deflection angle of the material guide plate 4 can be changed by moving it left and right.

[0035] The feed plate 4 is made of stainless steel, and the distance between its lower edge and the surface of the belt is set to 5~10cm.

[0036] The bottom of the frame 1 is provided with an adjustable mounting bracket, which includes a horizontal slide rail and locking screws to adapt to different models of belt conveyors.

[0037] The lead screw 2 is covered with a dustproof sleeve, the inner wall of which is filled with lubricating grease, and a limit block is provided at the end of the lead screw's lifting stroke.

[0038] Installation method:

[0039] 1. Install this device in front of the conveyor belt receiving point. If the conveyor belt deviates after the material 7 passes through, it can be manually adjusted at any time according to the direction of belt deviation.

[0040] 2. If the belt deviates to the left, adjust material 7 to move it slightly to the left. After observing, the belt will return to the correct position. If it deviates to the right, reverse the operation.

[0041] 3. The material of the feeding plate 4 is stainless steel plate, which reduces the frictional resistance of the material / 7. The insertion depth of the feeding plate 4 is designed so that the lower limit position will not scratch the belt. In actual operation, the feeding amount can be manually controlled according to the amount of material. Figure 2 As shown.

[0042] The advantages of this device are low investment, simple structure, easy operation, and obvious effect, avoiding damage to belts and equipment caused by forced correction.

[0043] This alignment device is a manual mechanical device. When the belt 8 runs off-track, manually turn the handwheel 3 to drive the screw 2 and the material guide plate 4 to move up and down to adjust the depth of the material guide plate 4 into the material. Move the lever 5 left and right to adjust the angle of the material guide plate 4. By moving the material left and right on the belt 8, the alignment purpose is achieved (suitable for materials with small particles, such as iron concentrate, dry tailings, coal powder, etc.).

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
