Description

Technical Field

[0001] The present disclosure relates to the technical field of tensioning adjustment devices, and in particular to a tensioning adjustment device and a conveying device. Background Art

[0002] With the development of society and economy, the use of automated equipment in industrial production is becoming more and more common. Replacing manual labor with automated equipment can effectively improve efficiency and reduce costs. Among them, the conveyor belt is a basic component of automated equipment. The current conveyor belt includes a bracket, which is rotatably connected to two rotating rollers. The same belt is mounted on the two rotating rollers, and one of the rotating rollers is driven by a motor on the bracket.

[0003] Current conveyor belts tend to lose tension after long-term use, seriously affecting transmission efficiency. Existing tension adjustment methods typically involve installing multiple tensioning pulleys on one side of the belt and adjusting the distance between them to adjust the belt tension. However, this adjustment method is inefficient for processing lines with multiple belts. Utility Model Content

[0004] A technical problem to be solved by the present disclosure is that the existing method of adjusting tension is not applicable to a processing line with multiple conveyor belts, resulting in low adjustment efficiency.

[0005] In order to solve the above technical problems, on the one hand, the embodiment of the present disclosure provides a tension adjustment device, comprising:

[0006] Total tension roller;

[0007] A plurality of sub-tensioning wheels are arranged at intervals along the axis direction of the main tensioning roller, and the multiple sub-tensioning wheels are coaxial;

[0008] An adjusting roller is arranged between the main tensioning roller and the sub-tensioning wheel, and the axial direction of the adjusting roller is consistent with the axial direction of the main tensioning roller;

[0009] The adjusting mechanism is used to adjust the heights of the main tensioning roller, the sub-tensioning wheel and the adjusting roller in the vertical direction respectively.

[0010] In some embodiments, the adjustment mechanism includes a base frame, a first adjustment component arranged on the base frame for adjusting the adjustment roller, a second adjustment component for adjusting the total tensioning roller, and a third adjustment component for adjusting the sub-tensioning wheel. The first adjustment component, the second adjustment component, and the third adjustment component are arranged at intervals and operate independently of each other.

[0011] In some embodiments, at least two groups of first adjustment components are provided, and the two groups of first adjustment components are arranged along the axial direction of the adjusting roller. The first adjustment component includes a lifting frame arranged on the base frame, a lifting screw rotatably arranged in the lifting frame, and a driving motor for driving the lifting screw to rotate. Lifting blocks are provided at both ends of the adjusting roller, and the lifting screw passes through the lifting block and is threadedly connected to the lifting block.

[0012] In some embodiments, the second adjustment assembly is provided with at least two groups and is arranged along the axial direction of the total tensioning roller. The second adjustment assembly includes a support frame, a limit frame arranged on the support frame, an adjustment rod slidably arranged on the limit frame, and an adjustment cylinder for driving the adjustment rod to move in a vertical direction. One end of the adjustment rod is connected to the adjustment cylinder, and the other end is connected to the total tensioning roller.

[0013] In some embodiments, a sliding groove is provided on the limiting frame along the vertical direction, and a limiting rod is provided in the sliding groove. The limiting rod passes through the adjusting rod and is suitable for sliding on the limiting rod to adjust the height of the adjusting rod.

[0014] In some embodiments, a stabilizing spring is wound around the limiting rod, one end of the stabilizing spring is connected to the bottom of the adjusting rod, and the other end is connected to the support frame.

[0015] In some embodiments, multiple groups of third adjustment components are provided on the chassis, and the multiple sub-tensioning wheels correspond one-to-one to the multiple groups of third adjustment components.

[0016] In some embodiments, a plurality of universal wheels are provided at the bottom of the chassis.

[0017] On the other hand, the present disclosure provides a conveying device, wherein the frame and the conveyor belt are provided in multiple groups, including a frame and a conveyor belt provided on the frame, and the conveyor belt is connected to the above-mentioned tensioning adjustment device.

[0018] In some embodiments, a plurality of spacers are provided at both ends of the conveyor belt.

[0019] Through the above technical solution, the present disclosure provides a tension adjustment device and a conveying device. During use, if it is necessary to adjust the tension of multiple transmission belts at the same time, first adjust the height of the main tensioning roller and the adjusting roller. When the main tensioning shaft and the adjusting roller have adjusted the tension of most transmission belts, check the tension of each transmission belt, and then adjust the sub-tensioning pulleys of the untensioned transmission belts to make all the conveyor belts in a stable state. If only a single transmission belt is loose, it is sufficient to adjust the sub-tensioning pulley alone. The tension adjustment device provided by the present disclosure can use the main tensioning shaft and the adjusting roller to adjust the tension of multiple transmission belts, and can also use the sub-tensioning pulleys to adjust the tension of a single transmission belt, greatly improving the adjustment efficiency.

[0033] On the one hand, referring to Figure 1 , an embodiment of the present disclosure provides a tension adjustment device, comprising,

[0034] Main tension roller 1;

[0035] A plurality of sub-tensioning wheels 2 are arranged at intervals along the axis direction of the main tensioning roller 1, and the sub-tensioning wheels 2 are coaxial;

[0036] An adjusting roller 3 is provided between the main tensioning roller 1 and the sub-tensioning wheel 2, and the axial direction of the adjusting roller 3 is consistent with the axial direction of the main tensioning roller 1;

[0037] The adjusting mechanism is used to adjust the heights of the main tensioning roller 1, the sub-tensioning wheel 2 and the adjusting roller 3 in the vertical direction respectively.

[0038] A tensioning adjustment device provided in an embodiment of the present disclosure includes a main tensioning roller 1, several sub-tensioning wheels 2, an adjusting roller 3 and an adjusting mechanism. The adjusting mechanism is used to adjust the heights of the main tensioning roller 1, the sub-tensioning wheels 2 and the adjusting roller 3 in the vertical direction respectively, thereby adjusting the tension of the transmission belt.

[0039] The total tensioning roller 1 is arranged horizontally in a cylindrical shape and spans across multiple transmission belts. When performing tensioning operations, the total tensioning roller 1 is adjusted through the adjustment mechanism to adjust the tension of multiple transmission belts at the same time. Compared with the traditional single adjustment method, it is simpler and more efficient.

[0040] Several sub-tensioning pulleys 2 are located on the same side of the main tensioning roller 1, and all the sub-tensioning pulleys 2 are coaxial, with their axes parallel to the axis of the main tensioning roller 1. Multiple sub-tensioning pulleys 2 are arranged at intervals along the axis direction of the main tensioning roller 1. Each sub-tensioning pulley 2 corresponds to a transmission belt. When the tension of a single transmission belt needs to be adjusted, the position of the sub-tensioning pulley 2 can be adjusted.

[0041] The adjusting roller 3 is located between the main tensioning roller 1 and the secondary tensioning pulley 2. It is cylindrical and horizontally arranged, with its axis parallel to that of the main tensioning roller 1. Vertically, the adjusting roller 3 is lower than the tensioning roller and the secondary tensioning pulley 2. In the cross-section of the main tensioning roller 1, the main tensioning roller 1, the secondary tensioning pulley 2, and the adjusting roller 3 form a triangular arrangement. Adjusting the adjusting roller 3 using the adjustment mechanism can also adjust the tension of multiple drive belts simultaneously.

[0042] During use, if the tension of multiple transmission belts needs to be adjusted simultaneously, first adjust the main tensioning roller 1 and the adjusting roller 3. After the main tensioning shaft and the adjusting roller 3 have adjusted the tension of most transmission belts, check the tension of each transmission belt and then adjust the sub-tensioning pulleys 2 of the untensioned transmission belts to stabilize all transmission belts 9. If only a single transmission belt is loose, it is sufficient to adjust the sub-tensioning pulley 2 alone. The tensioning adjustment device provided by the present disclosure can adjust the tension of multiple transmission belts using the main tensioning shaft and the adjusting roller 3, and can also adjust the tension of a single transmission belt using the sub-tensioning pulley 2, greatly improving adjustment efficiency.

Lifting blocks 31 are provided at both ends of the adjusting roller 3, and the lifting screw 52 passes through the lifting block 31 and is threadedly connected to the lifting block 31.

[0046] In some embodiments, at least two sets of first adjustment assemblies 5 are provided, one at each end of the adjusting roller 3. These two sets of first adjustment assemblies 5 allow for simultaneous adjustment of the height of the adjusting roller 3 from both sides, providing stable and convenient operation.

The drive shaft of the drive motor 53 is coaxially and fixedly connected to the lifting screw 52. Driven by the drive motor 53, the lifting screw 52 rotates, thereby moving the lifting block 31 vertically on the lifting screw 52, thereby lifting and lowering the adjusting roller 3 vertically. Two lifting frames 51 are located at either end of the base frame 4, and the drive motors 53 of the different first adjustment assemblies 5 operate synchronously. The two synchronously moving drive motors 53 drive both ends of the adjusting roller 3 to simultaneously raise and lower, ensuring stable and efficient operation.

[0049] In some embodiments, at least two sets of second adjustment assemblies 6 are provided, and the two sets of second adjustment assemblies 6 are respectively located at both ends of the main tensioning roller 1. The height of the main tensioning roller 1 can be adjusted simultaneously from both sides, which is stable and convenient. The second adjustment assembly 6 includes a support frame 61, which is arranged in a vertical direction and is located on the side of the main tensioning roller 1 away from the adjustment roller 3.

[0050] An adjustment cylinder 64 is mounted on the support frame 61. Its telescopic rod is vertically arranged, with its top end connected to a connecting block. The adjustment cylinders 64 of the different second adjustment assemblies 6 operate synchronously. Driven by the adjustment cylinders 64, the adjustment rod 63 rises and falls vertically, thereby driving the total tensioning roller 1 to rise and fall vertically. The present invention utilizes two synchronously moving adjustment cylinders 64 to simultaneously raise and lower both ends of the adjustment roller 3, resulting in stable and efficient operation.

[0051] Reference Figure 2 In some embodiments, a sliding groove 621 is provided on the limiting frame 62 in the vertical direction, and a limiting rod 622 is provided in the sliding groove 621.

The adjusting rod 63 can slide in the vertical direction along the limiting rod 622 under the drive of the adjusting cylinder 64. The adjusting rod 63 is limited by the limiting rod 622 to avoid horizontal displacement of the adjusting rod 63 during the lifting process, thereby improving the stability during adjustment.
