Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, and specifically relates to a belt support device for a belt conveyor. Background Art

[0002] A belt conveyor, also known as a belt conveyor, is widely used in various industries such as household appliances, electronics, electrical appliances, machinery, tobacco, injection molding, post and telecommunications, printing, food, etc. for the assembly, inspection, debugging, packaging and transportation of objects. The belt conveyor mainly consists of two end drive drums, a closed conveyor belt tightly sleeved thereon, and multiple groups of upper supporting rollers. Among them, the upper supporting rollers play a role in supporting the conveyor belt.

[0003] The existing roller body support structure of the upper supporting roller for supporting the belt is fixed. When transporting heavier objects, it can only provide rigid support and cannot buffer, which easily leads to a reduction in the service life of the roller body due to weakened load-bearing capacity. Moreover, after long-term use of the upper supporting roller, the problem of roller body depression is likely to occur. If the conveyor belt is not removed, it is impossible to know in time when to replace it, resulting in very inconvenient operation and maintenance.

[0004] Therefore, it is particularly important to design a belt support device for a belt conveyor to change the above technical defects and improve the overall practicality. Content of the Utility Model

[0005] The purpose of the utility model is to provide a belt support device for a belt conveyor to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A belt support device for a belt conveyor includes two groups of side plates symmetrically distributed left and right. A drive drum is rotatably connected between the two groups of side plates at the rear position. Multiple groups of concave brackets with the same interval are installed on the inner sides of the two groups of side plates and in front of the drive drum. An upper supporting roller is arranged inside the concave brackets. Roller buffer mechanisms for cooperating with the upper supporting roller are arranged on the left and right sides inside the concave brackets. A roller depression detection mechanism for cooperating with the upper supporting roller is arranged at the top inside the concave brackets;

[0008] The roller buffer mechanism includes an outer mounting frame installed on the inner side wall of the concave bracket. Waist-shaped grooves are opened downward at the top of the front and rear sides of the outer mounting frame. An inner mounting seat is arranged inside the outer mounting frame. Locking bolt assemblies extending outside the waist-shaped grooves are arranged on the front and rear sides of the inner mounting seat. A spring shock absorber is installed at the bottom inside the inner mounting seat. A sliding seat slidably matched with the inner mounting seat is installed at the top of the spring shock absorber. A fixed roller frame is arranged at the top of the sliding seat;

[0009] The idler depression detection mechanism includes a fixed cross bar installed at the inner top of the concave bracket. One end of the fixed cross bar is equipped with a reversible motor. The driving end of the reversible motor penetrates the inside of the fixed cross bar and is connected to a rotating screw. A screw sliding sleeve is threadedly sleeved on the outside of the rotating screw, and a contour sensor is installed at the top of the screw sliding sleeve.

[0010] As a preferred solution of the present invention, a controller is provided on the outside of the side plate. The controller contains multiple groups of display lights. The controller is respectively connected to the reversible motor and the contour sensor through wires, and the connection method is electrical connection.

[0011] As a preferred solution of the present invention, the opposite sides of two groups of the concave brackets at the same left and right positions are fixedly connected by bolts.

[0012] As a preferred solution of the present invention, mounting ears are provided on both the front and back sides of the outer mounting frame. Assembly bolts for fixedly connecting to the concave bracket are provided inside the mounting ears.

[0013] As a preferred solution of the present invention, the outer mounting frame and the inner mounting seat are designed with a separable structure, and the internal structure size of the outer mounting frame is adapted to the external structure size of the inner mounting seat.

[0014] As a preferred solution of the present invention, both ends of the upper idler are rotatably connected inside the fixed idler frame through bearing seats.

[0015] As a preferred solution of the present invention, a rectangular groove consistent with the length of the upper idler is opened at the top of the fixed cross bar, and the connection method between the screw sliding sleeve and the rectangular groove is a sliding connection.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. In the present invention, by providing a belt support device for a belt conveyor, a buffering structure is provided for the upper roller body by using the idler buffering mechanism. When transporting heavy objects, buffering and shock absorption can be carried out to avoid rigid support. Moreover, the divided left and right two-group segmented structure also improves the precise buffering force. At the same time, when the upper roller body is damaged, it is not necessary to replace the whole original one. Shortening the length of the upper roller body saves the costs of maintenance and replacement. At the same time, the upper roller body is convenient to operate during disassembly and installation, saving time.

[0018] 2. In the present utility model, a belt support device for a belt conveyor is provided. The concave detection of the upper roller can be carried out by a contour sensor that moves left and right. Based on the line structured light technology, a high-contrast light strip is projected in the area of the upper roller, and a matrix CCD camera is used to receive the scattered light, so as to obtain the cross-sectional shape or contour of the illuminated area on the surface of the upper roller, thereby completing the detection of the concave degree and pressure on the surface of the upper roller. It can be known in time without disassembling the conveyor belt, which greatly improves the detection efficiency and effect. Brief Description of the Drawings
