Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically to a multi-tail belt conveyor. Background Technology

[0002] In modern industrial production, belt conveyors are widely used as important material handling equipment. Traditional belt conveyors are mostly single-strip structures, meaning there is only one conveyor belt on the frame, allowing material to be transported from one end to the other. To achieve the function of diverting material to multiple locations from one end to the other, multiple independent single-strip belt conveyors of different lengths are often required. This not only significantly increases the size and floor space of the equipment, but each conveyor also requires side plates and a drive motor, resulting in waste of materials and parts and significantly increasing equipment costs. Utility Model Content

[0003] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a multi-tail belt conveyor that uses one driving wheel and multiple driven wheels, allowing one driving wheel to drive multiple conveyor belts, thereby reducing equipment size and cost.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a multi-tail belt conveyor, comprising:

[0005] The drive wheel is rotatably mounted on the frame.

[0006] Multiple driven wheels are rotatably mounted on the frame and parallel to the driving wheel. Each driven wheel is connected to the driving wheel by a conveyor belt, and a guide plate is provided between adjacent conveyor belts.

[0007] Multiple tensioning mechanisms are mounted on the frame and are used to tension the conveyor belts on multiple driven pulleys.

[0008] In this configuration, the coaxial driven wheels share a single tensioning mechanism.

[0009] Preferably, the tensioning mechanism includes two tensioning units, which are symmetrically arranged on both sides of the frame, and the two tensioning units are tensioned synchronously through a linkage shaft.

[0010] Preferably, the tensioning unit includes:

[0011] The slide rail is located on the side of the frame;

[0012] A lever, which is rotatably mounted on the frame;

[0013] A driven shaft is slidably mounted in a slide rail, and a driven wheel is rotatably mounted on the driven shaft;

[0014] A rocker arm, one end of which is hinged to the end of a lever, and one end of the driven shaft is mounted on the rocker arm.

[0015] Preferably, the rocker arm is threaded, the end of the driven shaft is provided with a through hole, the rocker arm passes through the through hole, and limit nuts are threadedly installed on the rocker arm on both sides of the through hole.

[0016] Preferably, a limit pin is fixed on the frame, and when the conveyor belt is in a tensioned state, the end of the rocker arm near the lever abuts against the limit pin.

[0017] Preferably, the linkage shaft is rotatably mounted on the frame, and the levers on the two tensioning units of the same tensioning mechanism are fixedly connected to the linkage shaft.

[0018] Preferably, the bottom of the frame is fixed with a support leg, and the lower end of the support leg is threaded with a foot brace.

[0019] Preferably, the frame is provided with multiple pad rails for supporting the conveyor belt.

[0020] Preferably, a plurality of lane divider brackets are fixed on the frame, and the lane divider panels are fixed on the frame by the plurality of lane divider brackets.

[0021] Preferably, a drive motor is fixedly mounted on the side of the frame near the drive wheel, a drive shaft is rotatably mounted on the frame, the drive motor drives the drive shaft to rotate, and the drive wheel is fixed on the drive shaft.

[0022] The beneficial effects of this utility model are as follows:

[0023] This utility model designs a driving wheel and multiple driven wheels. Each driven wheel is connected to the driving wheel through an independent conveyor belt, realizing the diversion function of "one-end input and multiple-end output". Multiple conveyor belts of different lengths can share the same driving shaft, which can increase the integration of the equipment. Compared with a single belt conveyor, it reduces the size and floor space of the equipment, improves the conveying efficiency, uses fewer materials and parts, and effectively reduces the cost of the equipment.

[0024] The present invention features a lane divider plate installed on the conveyor belt, which is fixed to the frame by a lane divider plate bracket. The lane divider plate can separate the transmission path on the conveyor belt, avoiding the mixing of materials from different lines. It is suitable for use in meat production line logistics aggregation and lane conveying scenarios.

[0025] The tensioning mechanism of this utility model adopts a symmetrical design. The levers in the two tensioning units are fixed by a linkage shaft to achieve synchronous rotation, which avoids conveyor belt deviation or wear caused by uneven tension on one side and improves the smoothness of operation.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] like Figures 1 to 6As shown in Embodiment 1 of this utility model, a multi-tail belt conveyor is provided. A drive shaft 2 is rotatably mounted on one end of the frame via bearings, and a drive motor 1 is fixedly mounted on one side of the frame, driving the drive shaft 2 to rotate. A drive wheel 3 is fixed on the drive shaft 2. Two driven shafts 6 are provided at the end of the frame away from the drive shaft 2. These two driven shafts 6 are parallel but at different distances from the drive shaft 2. Two driven wheels 7 are rotatably mounted on one driven shaft 6, and one driven wheel 7 is rotatably mounted on the other driven shaft 6. Each of these three driven wheels 7 has an independent conveyor belt wound around the drive wheel 3. Therefore, when one drive wheel 3 rotates, it can drive three conveyor belts to transport goods. In this way, the conveying task of multiple conveyors of the same height can be achieved by one conveyor, reducing the use of side plates and drive equipment, and lowering equipment costs.

[0038] Multiple support legs 11 are bolted to the bottom of the frame. Each support leg 11 has a threaded rod threaded to its bottom, and a foot brace is fixed to the bottom of the threaded rod. This allows the foot brace to contact the bottom surface by rotating the threaded rod, ensuring the frame and conveyor belt can be placed flat evenly in factory areas with uneven ground. Figure 1 As shown, the middle conveyor belt is longer than the two side conveyor belts, and the middle frame extends a longer distance towards the tail. The extended part of the frame is fixedly connected to the frame on the other side via connecting cross braces 12.

[0039] To increase the load-bearing capacity of the conveyor belt, multiple pad rails 4 are fixed on the frame. The pad rails 4 are located at the bottom of the upper conveyor belt and can support the upper conveyor belt. This solution also has multiple idler rollers 10 rotatably installed on the frame parallel to the drive shaft 2. Their function is to support the lower conveyor belt and reduce the sagging of the lower conveyor belt.

[0040] Since this solution has multiple conveyor belts, multiple tensioning mechanisms 5 are designed to adjust the tension of the conveyor belts. In this embodiment, there are two driven shafts 6, two driven wheels 7 are located on the same driven shaft 6, and another driven wheel 7 is located on a separate driven shaft 6. Therefore, this solution uses two tensioning mechanisms 5 to adjust the positions of the two driven shafts 6 respectively, so as to achieve tensioning of the three conveyor belts.

[0041] Example 2:

[0042] Based on Embodiment 1, the tensioning mechanism 5 designed in this utility model includes two symmetrically distributed tensioning units, which are respectively located on the frame at both ends of the driven shaft 6. Figure 4 and Figure 5As shown, the tensioning unit includes a long, narrow slide rail 51 on the side of the frame, a lever 52 rotatably mounted on the frame, and a rocker arm 53 hinged to one end of the lever 52. A linkage shaft 56 parallel to the driven shaft 6 is rotatably mounted on the frame, and the lever 52 is fixed to the linkage shaft 56. The linkage shaft 56 is fixed to the lever 52 near the rocker arm 53, which makes it easier for the operator to press the other end of the lever 52.

[0043] The rocker arm 53 has a threaded end away from the lever 52, allowing two limiting nuts 54 to be threaded onto it. The driven shaft 6 has a through hole at its end, through which the rocker arm 53 passes. The two limiting nuts 54 are located on either side of the driven shaft 6, constraining its position on the rocker arm 53. The rocker arm 53 is perpendicular to the driven shaft 6, and the end of the driven shaft 6 is slidably mounted in the slide rail 51.

[0044] With the above setup, when the user presses the end of the lever 52, the levers 52 on both sides of the frame can rotate around the linkage shaft 56 via the linkage shaft 56, thereby displacing the end of the rocker arm 53 that is hinged to the lever 52. This causes a change in the position of the lever 52, and the lever 52 drags the driven shaft 6 to move in the slide rail 51, thereby adjusting the distance between the driven shaft 6 and the drive shaft 2, and thus adjusting the tension of the conveyor belt.

[0045] To maintain the position of the rocker arm 53 and ensure that the driven shaft 6 remains stationary, thereby maintaining the tension of the conveyor belt, this invention includes a limit pin 55 fixed to the side of the frame. Figure 5 As shown, the limiting pin 55 is located below the line connecting the driven shaft 6 and the linkage shaft 56. Under the tension of the conveyor belt, the driven shaft 6 presses the end of the rocker arm 53 against the limiting pin 55, thereby preventing the driven shaft 6 from continuing to move towards the drive shaft 2 in the slide 51, thus keeping the conveyor belt taut.

[0046] Example 3:

[0047] Based on Embodiment 1 and Embodiment 2, as Figure 6 As shown, a guide rail bracket 8 is fixed on the frame, and three guide rail plates 9 are fixed under the guide rail bracket 8. The left and right guide rail plates 9 are located between the two side conveyor belts and the middle conveyor belt, and the middle guide rail plate 9 is located in the middle of the middle conveyor belt. These three guide rail plates 9 divide the three conveyor belts into four conveying paths. The guide rail plates 9 can prevent the goods on their respective conveying paths from deviating during the conveying process.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
