Description

Technical Field

[0001] This utility model relates to the field of conveying equipment, specifically to an integrated tensioning mechanism and conveyor. Background Technology

[0002] A narrow belt sorting machine is a belt conveyor that uses multiple parallel, equally spaced narrow belts as conveyor belts. It can be used in conjunction with roller-type lifting and transfer systems and is suitable for transporting various items to densely arranged sorting lanes or workstations. Because this equipment uses multiple narrow belts as conveyor belts, the length of each narrow belt has varying degrees of error during manufacturing. Therefore, an adjustment mechanism is required to ensure that the tension of all narrow belts is consistent, thereby ensuring the normal operation of the equipment.

[0003] Currently, common narrow belt conveyors have two independent tensioning mechanisms. One mechanism uses a tensioning roller to synchronously adjust the overall tension of all narrow belts, first adjusting the tension of most narrow belts to be roughly the same, and then using another adjustment mechanism to fine-tune one or more narrow belts whose tension is not up to standard. This design has two drawbacks: firstly, the adjustment positions are far apart, and after adjusting one tensioning mechanism, it is necessary to move to the other tensioning mechanism for adjustment, resulting in low adjustment efficiency; secondly, the tensioning mechanism is relatively complex, requiring more materials to manufacture, which will cause material waste and increase equipment costs.

[0056] The working principle of the integrated tensioning mechanism provided in this embodiment is explained below:

[0057] 1. Synchronous adjustment (overall adjustment)

[0058] First, adjust the tensioner pulley to its limit position 300 to be consistent. Figure 1 (The rightmost end of the middle horizontal support plate 210), then according to Figure 2 The assembly shown is an integrated tensioning mechanism, adjustable. Figure 2 The position of the integrated tensioning mechanism can be adjusted by using the second locking nut 450. Figure 4 As shown, adjusting the integrated tensioning mechanism to the left will simultaneously tighten the narrow belt, while adjusting it to the right will loosen it.

[0059] 2. Single-belt adjustment:

[0060] Because manufacturing errors are unavoidable, the lengths of several narrow belts in the equipment may vary slightly. In this case, simply adjusting the overall length is insufficient to achieve uniform tension across all belts; further adjustment is necessary. Figure 1 The tension pulley 300 is used to further adjust the longer belts individually.

[0061] The integrated tensioning mechanism provided in this application embodiment has at least the following advantages:

[0062] 1. Connecting plates 110 are provided at both ends of the tensioning support 100. The support adjustment assembly 400 fixes the connecting plates 110 to the frame 1, thereby fixing the integrated tensioning mechanism to the frame 1 and realizing the position adjustment and fixing function of the overall mechanism relative to the frame 1.

[0063] 2. Multiple tensioning wheel supports 200 are arranged side by side on one side of the tensioning assembly support 100, which can be used to assemble multiple tensioning wheels 300; one end of the transverse support plate 210 is connected to one of the tensioning assembly supports 100, and the longitudinal baffle 220 is fixed to the other end of the pair of transverse support plates 210; a sliding groove 211 is provided on the transverse support plate 210, and the tensioning wheel 300 is arranged between the pair of tensioning transverse support plates 210. The wheel axle of the tensioning wheel 300 is slidably connected to the sliding groove 211 through the flat tenon structure 310; the adjusting screw 510 is connected to the threaded hole on the transverse support plate 210, and the end of the adjusting screw 510 extends into the sliding groove 211 to adjust the position of the flat tenon structure 310, thereby realizing the adjustment of a single tensioning wheel 300.

[0064] 3. Compared to current narrow belt conveyors, it eliminates one tensioning roller used for adjusting overall tension, achieving the same adjustment function with an integrated tensioning mechanism and a smaller size.

[0065] In addition, this application embodiment also provides a conveyor, which can be a narrow belt conveyor, including the above-mentioned integrated tensioning mechanism, for assembling and adjusting the tension of several narrow belts.
