Description

Technical Field

[0001] This utility model relates to the field of conveyor belt protection, specifically to a device for preventing belt tearing. Background Technology

[0002] Currently, PSK idlers are only installed on one side of the end frame, and only three are installed on one end of the belt, meaning they only protect the left or right end of the belt. This still results in belt tearing. Furthermore, existing PSK idlers cannot adjust the position between the idler and the support, making them unsuitable for a wider range of belt sizes and limiting the device's versatility. Utility Model Content

[0003] The purpose of this invention is to provide a belt tear prevention device, which solves the problem that belts are easily torn and have poor universality.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A belt tear prevention device includes a truss and end frames. Multiple end frames are provided on the truss and are arranged along the axial direction of the truss. Each end frame includes an upper conveying port and a lower conveying port, and a set of PSK rollers are connected to the front and rear sides of the upper and lower conveying ports, respectively.

[0006] Furthermore, each set of PSK rollers includes six PSK rollers, with the six PSK rollers on the front and rear sides of the upper conveying port distributed circumferentially along the upper conveying port; and the six PSK rollers on the front and rear sides of the lower conveying port distributed circumferentially along the lower conveying port.

[0007] Furthermore, the six PSK rollers on the front side of the upper conveyor and the six PSK rollers on the rear side are arranged alternately to form a regular dodecagon; the six PSK rollers on the front side of the lower conveyor and the six PSK rollers on the rear side are arranged alternately to form a regular dodecagon.

[0008] Furthermore, the six PSK rollers on the front side of the upper conveyor port are symmetrically distributed with the six PSK rollers on the front side of the lower conveyor port, and the six PSK rollers on the rear side of the upper conveyor port are symmetrically distributed with the six PSK rollers on the rear side of the lower conveyor port.

[0009] Furthermore, the PSK idler roller includes a bracket and a belt roller, with the bracket detachably connected to the end frame and the belt roller rotatably connected to the bracket.

[0010] Furthermore, the bracket is integrally formed and includes a fixing part and a connecting part. The connecting part is located on both sides of the fixing part. The fixing part is provided with connecting holes and is detachably connected to the end frame by bolts. The connecting part is provided with adjustment holes, and the belt roller is connected to the connecting part through the adjustment holes.

[0011] Furthermore, the adjusting hole is specifically a bolt hole group, each bolt hole group including multiple bolt holes, and the belt roller is connected to the connecting part through the bolt holes.

[0012] Furthermore, the adjustment hole is specifically an elongated hole, and the belt roller is connected to the connecting part through the elongated hole.

[0013] Furthermore, the deflection angle between two adjacent PSK rollers in each group of PSK rollers is 30°.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] This invention features six PSK rollers mounted on each side of the frame, arranged in a staggered pattern along the circumference of the conveyor inlet to form a regular dodecagon. This ensures the belt is not torn by the gap between adjacent rollers when passing over them, maximizing belt protection. Furthermore, an adjustment hole is added to the connection point to adjust the relative position between the support and the belt rollers, accommodating belts of various widths and increasing the device's versatility. This invention not only boasts high versatility but also effectively protects the belt from tearing. Attached Figure Description

[0024] Example 1

[0025] like Figure 1As shown, a belt tear prevention device includes a truss 1 and end frames 2. Multiple end frames 2 are arranged on the truss 1 along its axial direction. Each end frame 2 includes an upper conveyor inlet and a lower conveyor inlet, with a set of PSK idlers 5 connected to the front and rear sides of each inlet. The conveyor belt starts at the lower conveyor inlet and connects to the PSK idlers 5. A first directional wheel 6 changes direction in front of the truss 1, connecting the belt to the upper conveyor inlet's PSK idlers 5. A second directional wheel 7 changes direction behind the truss 1, returning the belt to its starting point, completing one revolution. The PSK idlers prevent the conveyor belt from contacting the sharp ends of the end frames 2 and streamline the conveyor belt's movement.

[0026] like Figure 2 and Figure 3 As shown, each set of PSK rollers 5 includes six PSK rollers 5. The six PSK rollers 5 located on the front and rear sides of the upper conveyor inlet are distributed circumferentially along the upper conveyor inlet; the six PSK rollers 5 located on the front and rear sides of the lower conveyor inlet are also distributed circumferentially along the lower conveyor inlet. The conveyor belt is surrounded by the PSK rollers 5 to prevent tearing. The six PSK rollers 5 on the front side of the upper conveyor inlet and the six PSK rollers 5 on the rear side are arranged alternately to form a regular dodecagon; the six PSK rollers 5 on the front side of the lower conveyor inlet and the six PSK rollers 5 on the rear side are also arranged alternately to form a regular dodecagon. Figure 4 and Figure 5 As shown, the six PSK rollers 5 on the front side of the upper conveyor and the six PSK rollers 5 on the front side of the lower conveyor are symmetrically distributed, forming a flat-bottomed hexagon. The six PSK rollers 5 on the rear side of the upper conveyor and the six PSK rollers 5 on the rear side of the lower conveyor are symmetrically distributed, forming a pointed-bottomed hexagon. The deflection angle between any two adjacent PSK rollers 5 in each group is 30°. The conveyor belt will first pass behind the lower conveyor, where the PSK rollers 5 are pointed-bottomed hexagons. After passing through the lower conveyor, the flat-bottomed hexagons of the PSK rollers 5 on the front side of the lower conveyor fill the gaps in the pointed-bottomed hexagons. With the PSK rollers 55 arranged in an alternating pattern, the belt will not enter the gaps between two adjacent PSK rollers 5, and there will be no belt tearing due to the gaps restricting the belt's movement.

[0027] like Figure 6 and Figure 7As shown, the PSK idler roller 5 includes a bracket 51 and a belt roller 52. The bracket 51 is detachably connected to the end frame 2, and the belt roller 52 is rotatably connected to the bracket 51. The bracket 51 is integrally formed and includes a fixing part 511 and a connecting part 512. The connecting part 512 is located on both sides of the fixing part 511. The fixing part 511 has connecting holes and is detachably connected to the end frame 2 by bolts. The connecting part 512 has adjustment holes, and the belt roller 52 is connected to the connecting part through the adjustment holes. The adjustment holes are specifically bolt hole groups, each bolt hole group including multiple bolt holes 513, and the belt roller 52 is connected to the connecting part 512 through the bolt holes. Currently used PSK idler rollers 5 all have only one set of fixing positions on the connecting part 512, which restricts the belt roller 52 to a specific position and cannot be applied to belts with slightly larger widths, reducing the universality of the device. This device can adjust the position between the belt roller 52 and the connecting part 512 to increase the diameter of the inscribed circle of the regular hexagon formed by the PSK roller 5, thereby improving the versatility of the device.

[0028] Example 2

[0029] like Figure 8 As shown, this embodiment differs from Embodiment 1 in that the adjustment hole is specifically an elongated hole 514, and the belt roller 52 is connected to the connecting part 512 through the elongated hole 514. The position of the belt roller 52 relative to the bracket 51 can be adjusted through the elongated hole 514. When adjusting the position of the belt roller 52 in the elongated hole 514, it is necessary to ensure that the corresponding position of each belt roller 52 in the elongated hole 514 is the same, so as to ensure that the PSK roller 5 on each side forms a regular hexagon.

[0030] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
