Description

Technical Field

[0001] The utility model relates to a conveyor belt tensioning and adjusting mechanism, in particular to a mesh belt tensioning device for conveying equipment. Background Art

[0002] Conveying equipment generally consists of a drive motor, a driving wheel, a driven wheel, a conveyor belt, a tensioning wheel, a side plate, a bracket, etc. The tensioning wheel is mainly used to tension the driving wheel and the driven wheel to straighten the conveyor belt and facilitate smooth material transportation. There are generally the following ways to tension the conveyor belt: (1) By adjusting the center distance between the driving wheel and the tail wheel (2) The center distance between the driving wheel and the tail wheel remains unchanged, and an intermediate tensioning wheel is added in the middle of the conveyor belt return (3) A driven wheel with a spring is added under the return mesh belt to tension the return mesh belt.

[0003] Generally speaking, these three methods are very practical in most cases, but they also have their flaws. Method (1) will increase the length of the conveyor along the conveying direction, which will increase the overall dimensions of the conveying equipment. It is not suitable for those occasions with narrow space or high requirements for space utilization. Method (2) requires adding 3 sets of driven wheels, which are in a "T" shape. This method will increase the processing cost and make the structure complicated. If a fault occurs, it is not convenient to repair the whole machine. Method (3) generally also requires a combination of multiple driven wheels to achieve the tensioning function, and the structure is slightly complicated. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0023] In some embodiments, Figure 1 and Figure 2 As shown, a mesh belt tensioning device for conveying equipment is provided, which mainly includes a mounting plate 10, a tail wheel 20 and a conveyor belt 30. The tail wheel 20 is mounted on the upper end of the mounting plate 10 and is arranged corresponding to the tensioning wheel. The two ends of the conveyor belt 30 are respectively sleeved on the tail wheel 20 and the tensioning wheel, forming a conventional assembly method of an existing conventional conveyor belt, a driving wheel and a tail wheel.

[0024] In order to overcome the defects of the conventional conveyor belt tensioning method, the device also includes a tensioning wheel 40 and a supporting wheel 50 installed at the lower end of the mounting plate 10, and the tensioning wheel 40 is adjustably installed in the adjusting slot 13 at the lower end of the mounting plate 10. The tensioning wheel 40 and the supporting wheel 50 constitute two driven wheels at the tail end of the conveyor belt, and the tensioning wheel 40 is an adjustable structure. By adjusting the position of the tensioning wheel 40, the tensioning adjustment of the conveyor belt 30 is achieved. The device has a simple structure, and only needs to add a tensioning wheel 40 and a supporting wheel 50 as driven wheels on the basis of the original driving wheel and tail wheel, so that the center distance between the driving wheel and the tail wheel can be kept unchanged while achieving the tensioning function.

[0025] In some of the embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the mounting plate 10 is made of stainless steel plate or aluminum alloy plate and is fixedly mounted on the frame at the tail end of the conveyor. The mounting plate 10 is an inverted U-shaped plate structure as a whole, with a square plate 11 on the left side and an inverted trapezoidal plate 12 on the right side. The square plate 11 and the inverted trapezoidal plate 12 are an integral structure, and the supporting wheel 50 is mounted at the lower end of the square plate 11, and the tail wheel 20 is mounted at the upper end of the inverted trapezoidal plate 12.

[0026] In addition, in order to facilitate the installation and tensioning adjustment of the tensioning wheel 40, the adjustment long hole 13 is opened at the lower end of the inverted trapezoidal plate 12, and a limiting long groove 14 for limiting the installation of the adjustment shaft 41 is opened at the position corresponding to the adjustment long hole 13 on the inverted trapezoidal plate 12. One end of the tensioning wheel 40 is designed as a large and small head structure, the end face of the large head is embedded in the limiting groove 14, which plays the role of axial limiting, and the small head is movably arranged in the adjustment long hole 13 to flexibly adjust its center distance with the tail wheel 20, and is locked and fixed with an adjusting bolt 42.

[0027] In some of the embodiments, Figure 1As shown, in order to maintain the stability of the conveyor belt 30 and keep the running path of the conveyor belt 30 at the driving wheel end unchanged, the tail wheel 20, the tension wheel 40 and the supporting wheel 50 are arranged in a triangle. The conveyor belt 30 is arranged along the outer sides of the tail wheel 20 and the tension wheel 40 to the inner side of the supporting wheel 50 in sequence. The structural arrangement is reasonable, and the center distance between the driving wheel and the tail wheel 20 can be kept unchanged while realizing the tensioning function.

[0028] In addition, it is worth noting that Figure 1 As shown, the tail wheel 20 is a driven wheel, and the other end of the conveyor belt 30 is sleeved on a driving wheel flush with the tail wheel 20. The diameter of the tail wheel 20 is equal to the diameter of the tension wheel 40, and both are larger than the diameter of the supporting wheel 50. The supporting wheel 50 mainly plays a guiding role, and the relatively larger diameter of the tension wheel 40 facilitates the adjustment of the tension of the conveyor belt 30.

[0029] In some of the embodiments, Figure 2 and Figure 3 As shown, the tension wheel 40 is adjustably installed in the limiting long slot 14 using an adjusting shaft 41 and is locked and fixed using an adjusting nut 42. Specifically, a screw head 411 is provided at one end of the adjusting shaft 41, and the screw head 411 passes through the adjusting long hole 13 and is locked and fixed using an adjusting nut 42.

[0030] like Figure 1 and Figure 2 As shown, the working principle of the mesh belt tensioning device for conveying equipment is as follows: the conveyor belt 30 passes through the tail wheel 20, the tensioning wheel 40, and the supporting wheel 50. The tensioning wheel 40 can adjust the center distance between itself and the tail wheel 20 through the locking nut 42 in the adjusting slot 13, so as to achieve the effect of tensioning the conveyor belt 30, and at the same time, the center distance between the tail wheel 20 and the driving wheel (not shown in the figure) remains unchanged.

[0031] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection.

In the absence of conflict, the same embodiment and different embodiments of the present utility model can be combined with each other;
