Description

Technical Field

[0001] The utility model belongs to the technical field of transfer equipment, in particular to an adjustable guardrail and a conveyor suitable for a conveyor belt. Background Art

[0002] Conveyor belt, also known as transport belt, is a composite product of rubber, fiber, metal, or plastic and fabric used in conveyor belts to carry and transport materials.

[0003] When conveying narrow food packaging boxes whose specifications are much smaller than the belt width, traditional conveyor belts are less likely to deviate from the belt surface due to their small weight. However, when transporting larger wide boxes, the deviation phenomenon is obvious because the boxes are too wide, and they are prone to rushing through the guardrail and falling due to inertia, causing damage to materials such as cans in the boxes.

[0004] In the prior art, guardrails are installed on the racks on both sides of the belt to prevent materials from falling outward, but the current guardrails are fixed and cannot be moved. Therefore, there is a problem that the guardrails cannot be adjusted according to the specifications of the boxes being transported, and thus cannot adapt to boxes of larger specifications. Utility Model Content

[0005] In order to solve the problem of adaptive adjustment for deviation of boxes of different specifications on the belt surface caused by the existing fixed setting of guardrails, the utility model provides an adjustable guardrail and a conveyor suitable for a conveyor belt.

[0006] The utility model is realized by the following technical solutions:

[0007] An adjustable guardrail suitable for a conveyor belt, comprising a fine-tuning unit installed on both sides of the belt and a protective plate connected to the fine-tuning unit; the fine-tuning unit comprises a fixing seat, the fixing seat is provided with a supporting bolt, the supporting bolt is threadedly connected with a fine-tuning nut, the outer wall of the fine-tuning nut is provided with a supporting ring with a vertical axis, and a supporting rod is provided inside the supporting ring; the protective plate is arranged on the inner side of the supporting rod and extends above the belt.

[0008] Rotate the fine-tuning nut to adjust the position of the support ring of the socket support rod on both sides of the support bolt, and then fine-tune the position of the protective plate to achieve protective adaptation to boxes of different specifications; the adaptive adjustment to boxes of different specifications can help to quickly guide the material, avoid the risk of material falling, and avoid material accumulation.

[0009] Furthermore, a limiting ring is provided at the lower part of the support rod, which can cooperate with the support ring to support the support rod. The limiting ring cooperates with the support ring to limit the stability of the height of the protective plate before and after adjustment.

[0010] A conveyor includes a frame and an adjustable guardrail; two corresponding fixed seats on both sides of a belt are connected by an expansion unit; the expansion unit is installed under the frame to adjust the distance between the two corresponding fixed seats. Under the action of the expansion unit, the adjustment range of the distance between the adjustable guardrails on both sides can be increased.

[0011] Furthermore, the expansion unit includes two gear plates 1 and two toothed strips; the two gear plates 1 are rotatably arranged below the frame through a rotating shaft, and the two gear plates 1 are distributed in a direction across the belt; the length direction of the two toothed strips is perpendicular to the moving direction of the belt, and the two toothed strips are respectively meshed with the two gear plates 1; the fixing seat is connected to the outer end of the toothed strip. The meshing action of the gear plate 1 and the toothed strip helps to stabilize the pulling and adjusting of the toothed strip.

[0012] Furthermore, the frame is provided with a guide rail matched with the toothed strip; the guide rail is threadedly connected with a locking bolt capable of fastening the toothed strip. The guide rail supports the toothed strip, and the locking bolt fixes the position of the toothed strip.

[0013] Furthermore, a bearing plate for supporting the toothed strip is provided on the rotating shaft below the gear plate 1, which helps to enhance the support for the toothed strip part meshing with the gear plate 1.

[0014] Furthermore, a coaxially rotating gear disc 2 is provided below the gear disc 1, and a synchronous belt is sleeved between the two gear discs 2. By the cooperation between the synchronous belt and the two gear discs 2, the protective plate on either side can be pulled out, so that the protective plates on both sides can be adjusted synchronously and relatively.

[0015] Furthermore, two toothed strips are arranged at diagonal positions of the two gear plates.

[0016] It can be seen from the above technical scheme that the beneficial effects of the utility model are: by rotating the fine-tuning nut, the position adjustment of the support ring of the socket support rod on both sides of the support bolt is completed, and then the position adjustment of the protective plate is completed to achieve protective adaptation to boxes of different specifications; the adaptive adjustment to boxes of different specifications can help to quickly guide the material, avoid the risk of material falling, and also avoid the accumulation of materials.
