Description

Technical Field

[0001] This invention relates to a turning device for a belt conveyor, and more particularly to an auxiliary device for turning belts at large angles. Background Technology

[0002] Existing belt conveyors all use a structure consisting of a belt, belt idlers, and a frame. The belt is a reciprocating belt that is integrally fitted onto the drive roller and the driven roller. The upper part of this reciprocating belt is a channel for transporting materials and has a certain width. To make it turn, the existing technology mainly uses the compression of the belt. This method can only meet the turning of more than 10 degrees. It cannot work beyond that, and will cause material spillage, almost no material being transported on the belt, as well as many problems such as belt tearing and motor burnout. However, large-angle turns are unavoidable during the conveying process. Existing equipment cannot achieve this or has a short lifespan and is difficult to debug, thus failing to meet production needs. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a large-angle belt turning auxiliary device to assist in realizing large-angle turns of belt conveyors. It has a long service life, is easy to debug, convenient to install, and works stably.

[0004] To achieve the above objectives, the technical means adopted by the present invention is as follows: a large-angle belt turning auxiliary device, including a turning frame and an auxiliary belt mechanism. The auxiliary belt mechanism is installed on the turning frame. The auxiliary belt mechanism includes an auxiliary belt and belt rollers sleeved at both ends of the auxiliary belt, as well as an upper auxiliary component and a lower auxiliary component. The upper auxiliary component gathers the upper auxiliary belt into a hollow open circle, circle or quasi-circle with an upward cross-section, and wraps it upward around the upper belt of the belt conveyor. The lower auxiliary component gathers the lower auxiliary belt into a hollow open circle, circle or quasi-circle with a downward cross-section, and wraps it upward around the lower belt of the belt conveyor.

[0005] Furthermore, the package can be a full package or a partial package. When the upper or lower auxiliary belt is a hollow circle or a near-circular shape, it is a full package; when the upper or lower auxiliary belt is a hollow open circle or a near-open circle, it is a partial package.

[0006] Furthermore, the inner surface of the upper auxiliary belt contacts the outer surface of the upper belt of the turning section of the conveyor belt, and the upper belt of the turning section of the conveyor belt is located in the upper auxiliary belt of the auxiliary belt. The inner surface of the lower auxiliary belt contacts the outer surface of the lower belt of the turning section of the conveyor belt, and the lower belt of the turning section of the conveyor belt is located in the lower auxiliary belt of the auxiliary belt. The friction between the auxiliary belt and the conveyor belt drives the auxiliary belt to rotate.

[0007] The biggest problem with existing belt conveyor bends is that as the bend angle increases, the bottom of the belt's arc changes from being perpendicular to the horizontal plane to nearly parallel to it. At this point, the belt has no load-bearing capacity, causing material spillage. To solve this problem, existing technologies, including those proposed by the inventors, have tried various methods, such as using auxiliary components to correct the belt's shape to prevent spillage. However, while these solutions work for small bends, for large bends, not only does material spillage occur, but the auxiliary components can also cause the belt to tear. After much deliberation, the inventors realized that focusing solely on the belt itself is insufficient to solve this problem. The present invention offers a solution that breaks away from this approach, providing an auxiliary belt mechanism that wraps around the belt. This not only solves the material spillage problem and the bend problem but also prevents belt tearing.

[0008] Furthermore, the auxiliary belt mechanism also includes several auxiliary rollers, which are mounted on the turning frame and located above or below the auxiliary belt for supporting or pressing the auxiliary belt.

[0009] Furthermore, the upper surface of the upper frame of the turning frame is provided with an upper auxiliary component, the lower surface of the upper frame is provided with a lower auxiliary component, and the upper surface of the lower frame of the turning frame is provided with a lower belt auxiliary component. Both the upper and lower auxiliary components include a gathering mechanism at the front of the turn, a raising mechanism at the turn, and a releasing mechanism at the rear of the turn. The lower belt auxiliary component includes a lower belt gathering mechanism at the front of the turn and a lower belt releasing mechanism at the rear of the turn. The gathering mechanism of the upper auxiliary component gradually gathers the auxiliary belt into an upward arc, and the raising component continues to gather the auxiliary belt into... The upper opening is round or near-round. The unwinding assembly gradually releases the auxiliary belt from the turn to the entry state. The lower auxiliary assembly's gathering mechanism gradually gathers the lower auxiliary belt into a downward arc, while the lower belt auxiliary assembly's lower belt gathering mechanism gathers the lower belt into an upward arc. The bulging mechanism continues to gather the lower auxiliary belt into a lower opening round or near-round, while simultaneously wrapping the lower belt within the lower auxiliary belt. The unwinding assembly gradually releases the auxiliary belt from the turn to the entry state, while the lower belt unwinding mechanism gradually releases the lower belt to the entry state.

[0010] Furthermore, both the gathering mechanism and the releasing mechanism are composed of vertical rollers arranged at an arc angle that gradually converges from one side to the other. The vertical rollers include a vertical roller frame and a roller mounted on the vertical roller frame. One end of the vertical roller frame is connected to the turning frame, and the other end is suspended in the air. The roller is mounted on the vertical roller frame through a roller shaft.

[0011] Furthermore, the bulging mechanism consists of several sets of concave drum-shaped roller groups installed on the turning frame. Each set of concave drum-shaped roller groups consists of two concave drum-shaped rollers symmetrically installed, with an open circle or near-circle formed between the two concave drum-shaped rollers.

[0012] Furthermore, the width of the auxiliary belt is greater than the width of the conveyor belt, but less than three times the width of the conveyor belt.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. No external power drive is required. The synchronous rotation of the two belts is achieved by the friction between the belt conveyor and the auxiliary belt, which saves the space for drive installation and solves the problem of synchronization.

[0015] 2. By wrapping the auxiliary belt, the belt of the conveyor belt is protected to prevent tearing, and the material spilled inside the conveyor belt can be collected and moved with the conveyor belt until it is finished turning, and then fall back onto the belt of the conveyor belt, thus ensuring the material is conveyed.

[0016] 3. It enables large-angle turns of the belt conveyor, and has a long service life, simple debugging, convenient installation, and stable operation. Attached Figure Description

[0023] like Figure 1As shown, a large-angle belt turning auxiliary device includes a turning frame 1 and an auxiliary belt mechanism 2. The auxiliary belt mechanism 2 is installed on the turning frame 1. The auxiliary belt mechanism 2 includes an auxiliary belt 21 and belt rollers sleeved at both ends of the auxiliary belt, as well as an upper auxiliary component 3 and a lower auxiliary component 4. The upper auxiliary component 3 gathers the upper auxiliary belt 22 into a hollow open circle, circle or quasi-circle with an upward cross section, and wraps it upward around the upper belt 5 of the belt conveyor. The lower auxiliary component 4 gathers the lower auxiliary belt 23 into a hollow open circle, circle or quasi-circle with a downward cross section, and wraps it upward around the lower belt 6 of the belt conveyor.

[0024] The aforementioned wrapping can be either full or partial. Full wrapping occurs when the upper or lower auxiliary belt is a hollow circle or near-circular shape; partial wrapping occurs when the upper or lower auxiliary belt is a hollow open circle or near-open circle. The purpose of wrapping is to solve two main problems: 1. material spillage, and 2. belt tearing. Therefore, the wrapping achieved by the upper auxiliary component 3 and the lower auxiliary component 4 can be either full or partial.

[0025] The biggest problem with existing belt conveyor bends is that as the bend angle increases, the bottom of the belt's arc changes from being perpendicular to the horizontal plane to nearly parallel to it. At this point, the belt has no load-bearing capacity, causing material spillage. To solve this problem, existing technologies, including those proposed by the inventors, have tried various methods, such as using auxiliary components to correct the belt's shape to prevent spillage. However, while these solutions work for small bends, for large bends, not only does material spillage occur, but the auxiliary components can also cause the belt to tear. After much deliberation, the inventors realized that focusing solely on the belt itself is insufficient to solve this problem. The present invention offers a solution that breaks away from this approach, providing an auxiliary belt mechanism that wraps around the belt. This not only solves the material spillage problem and the bend problem but also prevents belt tearing.

[0026] Preferably, the inner surface of the upper auxiliary belt 22 is in contact with the outer surface of the upper belt 5 of the turning section of the conveyor belt, and the upper belt 5 of the turning section of the conveyor belt is located in the upper auxiliary belt 22 of the auxiliary belt. The inner surface of the lower auxiliary belt 23 is in contact with the outer surface of the lower belt 6 of the turning section of the conveyor belt, and the lower belt 6 of the turning section of the conveyor belt is located in the lower auxiliary belt 23 of the auxiliary belt. The auxiliary belt 21 rotates due to friction with the conveyor belt.

[0027] The auxiliary belt 21 is driven to rotate by the friction of the conveyor belt, eliminating the need for external power. Synchronization between the two belts is achieved through friction, ensuring that materials return to the upper belt more effectively. This technology saves space in the drive system and solves the synchronization problem.

[0028] The auxiliary belt mechanism 2 also includes a plurality of auxiliary rollers 14, which are mounted on the turning frame 1. The auxiliary rollers 14 are located above or below the auxiliary belt 21 and are used to support or press the auxiliary belt 21.

[0029] As a specific structural design, such as Figure 3 As shown, the upper auxiliary component 3 is provided on the upper surface of the upper frame 11 of the turning frame 1, the lower auxiliary component 4 is provided on the lower surface of the upper frame 11, and the lower belt auxiliary component is provided on the upper surface of the lower frame 12 of the turning frame 1. The upper auxiliary component 3 and the lower auxiliary component 4 both include a gathering mechanism 7 provided at the front of the turn, a raising mechanism 10 provided at the turn, and a releasing mechanism 8 provided at the rear of the turn. The lower belt auxiliary component includes a lower belt gathering mechanism 9 provided at the front of the turn and a lower belt releasing mechanism provided at the rear of the turn.

[0030] The gathering mechanism 7 of the upper auxiliary component gradually gathers the auxiliary belt into an upward arc, the raising mechanism continues to gather the auxiliary belt into an upper open circle or a circle-like shape, and the releasing mechanism gradually releases the auxiliary belt that came out from the turning point back to the state when it entered.

[0031] The lower auxiliary assembly's gathering mechanism 7 gradually gathers the lower auxiliary belt into a downward arc, while the lower belt auxiliary assembly's lower belt gathering mechanism 9 gathers the lower belt into an upward arc. The raising mechanism 10 continues to gather the lower auxiliary belt into a lower open circle or near-circle, while simultaneously wrapping the lower belt within the lower auxiliary belt. The releasing mechanism 8 gradually releases the auxiliary belt that came out from the bend back to the state it entered, while the lower belt releasing mechanism gradually releases the lower belt back to the state it entered.

[0032] As a design, such as Figure 4 As shown, the gathering mechanism and the releasing mechanism are both composed of vertical rollers 13 arranged at an angle that gradually converges from one side to the other into an arc. The vertical roller 13 includes a vertical roller frame and a roller mounted on the vertical roller frame. One end of the vertical roller frame is connected to the turning frame, and the other end is suspended. The roller is mounted on the vertical roller frame through a roller shaft.

[0033] The bulging mechanism 10 consists of several sets of concave drum-shaped roller groups installed on the turning frame. Each set of concave drum-shaped roller groups consists of two concave drum-shaped rollers symmetrically installed, with an open circle or near-circle formed between the two concave drum-shaped rollers.

[0034] Preferably, the width of the auxiliary belt is greater than the width of the conveyor belt, but less than three times the width of the conveyor belt.

[0035] This invention requires no external power drive, achieving synchronous rotation of the two belts through friction between the conveyor belt and the auxiliary belt. This saves space for drive installation and solves the synchronization problem. The auxiliary belt protects the conveyor belt from tearing and collects any spilled material, allowing it to move with the conveyor until it returns to the conveyor belt after the turn, ensuring material transport. It enables large-angle turns for the conveyor belt and features a long service life, simple debugging, convenient installation, and stable operation.

[0036] Although the specific embodiments of the present invention have been described and explained in detail above, it should be noted that we can make various equivalent changes and modifications to the above embodiments based on the concept of the present invention. As long as the resulting functions do not exceed the spirit covered by the specification, they should all be within the protection scope of the present invention.
