Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to an adjustable belt stabilizer. Background Technology

[0002] Currently, belt conveyors are rapidly developing towards larger capacity, longer distances, and higher belt speeds. The long conveyor distances and large capacity result in high tension, and using high-strength belts leads to poor belt troughing. Typically, this is addressed by increasing the central drive or reducing the conveyor's capacity to lower the belt strength, or by increasing the belt width to ensure the troughing performance of the conveyor's supporting roller assembly. Additionally, single-sided guide rollers are added to assist in belt troughing.

[0003] Adding a central drive or reducing the conveyor's capacity cannot achieve high-volume, long-distance transportation. Furthermore, adding a central drive introduces an additional point of failure, requiring workers for maintenance and repair, thus increasing labor costs. While increasing the belt width is beneficial for belt troughing, it also increases the investment cost of the conveyor. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology where the conveyor belt is difficult to form a trough during transportation, resulting in the spillage of materials on the ground, one of the purposes of this utility model is to provide an adjustable belt stabilizing device.

[0005] One of the objectives of this utility model is achieved through the following technical solution: an adjustable belt stabilizing device, comprising a belt pressing bracket and a conveyor belt; the conveyor belt is disposed on the lower side of the belt pressing bracket, and a clamping plate is fixedly connected to the outer side of the belt pressing bracket; a total of four clamping plates are provided, arranged in pairs; a belt pressing roller is movably connected between each pair of clamping plates; adjusting bolts are threaded to both ends of the belt pressing bracket; a spring is fixedly connected to the lower side of the adjusting bolt; a fixing plate is fixedly connected to the lower end of the spring; and a conveyor longitudinal beam is disposed on the lower side of the fixing plate. This facilitates the troughing of the conveyor belt.

[0006] According to the adjustable belt stabilizer, a U-bolt is bolted between the fixing plate and the conveyor longitudinal beam. This facilitates fixing the fixing plate to the conveyor longitudinal beam.

[0007] According to the adjustable belt stabilizing device, a nut is threaded onto the outer side of the adjusting bolt. This facilitates adjustment and fixation of the belt support.

[0008] According to the adjustable belt stabilizing device described above, a set of idler rollers is provided on the underside of the conveyor belt. This facilitates transportation after the conveyor belt is troughed.

[0009] According to the adjustable belt stabilizer described above, material is disposed on the upper side of the conveyor belt, facilitating material transportation.

[0010] According to the adjustable belt stabilizing device, the belt pressing bracket is U-shaped to facilitate the troughing of the conveyor belt.

[0011] The above solution has the following advantages: by setting up the belt pressing bracket, belt pressing roller, clamping plate, adjusting bolt, nut, spring, fixing plate and U-bolt, the conveyor belt can be pressed into a groove before the material is transported without increasing the width of the conveyor belt, and then transported by the idler roller group, which facilitates the transportation of materials and reduces transportation costs.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] Reference Figure 1-4An adjustable belt stabilizing device includes a belt pressing bracket 1 and a conveyor belt 9. The conveyor belt 9 is located on the lower side of the belt pressing bracket 1. Four clamping plates 3 are fixedly connected to the outer side of the belt pressing bracket 1, arranged in groups of two. A belt pressing roller 2 is movably connected between each group of clamping plates 3. Adjusting bolts 4 are threaded to both ends of the belt pressing bracket 1. A spring 6 is fixedly connected to the lower side of the adjusting bolt 4. A fixing plate 7 is fixedly connected to the lower end of the spring 6. A conveyor longitudinal beam 10 is located on the lower side of the fixing plate 7. A U-bolt 8 is bolted between the fixing plate 7 and the conveyor longitudinal beam 10. A nut 5 is threaded to the outer side of the adjusting bolt 4. A roller group 11 is located on the lower side of the conveyor belt 9, and material 12 is located on the upper side of the conveyor belt 9. The belt pressing bracket 1 is U-shaped. When using the adjustable belt stabilizing device, the operator first adjusts the fixing plate 7. The U-bolt 8 is fixed to the longitudinal beam 10 of the conveyor. Then, the operator pulls the belt pressing bracket 1, which pulls the spring 6 to stretch and move. Then, the conveyor belt 9 is pressed by the belt pressing roller 2 on the outside of the clamping plate 3. Then, under the action of the spring 6, the conveyor belt 9 is gradually pressed and bent into a groove, so that the conveyor belt 9 is close to the idler roller group 11. Finally, the nut 5 is rotated to stabilize the entire structure of belt pressing bracket 1, belt pressing roller 2 and clamping plate 3. The adjusting bolt 4 plays a role in stabilizing the entire structure. The setting of belt pressing bracket 1, belt pressing roller 2, clamping plate 3, adjusting bolt 4, nut 5, spring 6, fixing plate 7 and U-bolt 8 does not require increasing the width of the conveyor belt 9. The conveyor belt 9 is pressed into a groove before transporting the material 12 and then transported by the idler roller group 11, which facilitates the transportation of the material 12 and reduces transportation costs.

[0022] Working Principle: In the initial stage of operation of the belt conveyor, due to the deep trough angle structure of the conveyor roller group 11 and the high-strength belt 9, which is strong and thick, it cannot enter the trough on its own. The pressure rollers 2 on both sides of the pressure support 1 contact the edges of the conveyor belt 9. The spring 6 is in the maximum tension state at the beginning of use. During the operation of the conveyor belt 9, the spring 6 pulls back, gradually changing the initial shape of the conveyor belt 9, and the middle part is concave and slowly forms a trough. After the conveyor belt 9 forms the trough angle, it begins to carry the material 12. Under the combined action of the gravity of the material 12 and the trough angle of the roller group 11, the conveyor belt 9 gradually contacts each roller of the roller group 11, forming the final required running shape and achieving stable operation. The pressure rollers 2 have protruding baffles on both sides, which can effectively prevent the conveyor belt 9 from running off-center during operation. The adjusting bolts 4 play a stabilizing role for the pressure support 1 during the pullback of the spring 6. After the conveyor belt 9 enters the trough, the position of the adjusting nut 5 is used to fix it.

[0023] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
