Description

Technical Field

[0001] The utility model belongs to the technical field of waste belt edge trimming and recycling, and particularly relates to a device for recycling waste belt edge trimming. Background Art

[0002] The belt surfaces of the belt conveyors in the crossheading of the fully mechanized mining face have different specifications. For example, the 4 - coal belt surface 2500S(3 + 3) has a width of 1400 mm; the 3 - coal belt surface is 1800S(3 + 2) with a width of 1200 mm. Generally, when the 4 - coal 1400 - mm belt surface wears to a width less than 1300 mm, it will no longer be used; when the 3 - coal belt surface wears to a width less than 1100 mm, it will no longer be used. The width of the driving belt in the heading is 1000 mm.

[0003] The belt is a relatively large - loss component on the belt conveyor. Especially during the process of transporting materials, the edge part of the belt is extremely prone to excessive abrasion, resulting in edge cracking, wear - induced narrowing, and profile notches of the belt. Therefore, if not replaced, it is very easy for the belt to break during the process of transporting materials with load, thus triggering serious work - safety accidents.

[0004] Since the belt is a consumable part, only the edge part is damaged during its use. Directly discarding it not only causes serious economic losses but also leads to an excessively high use cost of production equipment.

[0005] During the production process, since the widths of the belts used on different belt conveyors are different, in the actual production process, if the large - sized and worn - out belt is cut at the edge - worn position and then replaced on the belt conveyor that requires a smaller - sized and width - matched belt, it not only effectively reduces the replacement amount of the belt on the belt conveyor but also realizes waste utilization, greatly improves the economic value, and at the same time reduces the equipment use cost.

[0006] However, during the actual working process, since the length of the belt on the belt conveyor is often large, therefore, how to cut off the worn - out edge of the belt to form a belt that can be used on other belt conveyors for waste utilization is of great significance.

[0007] However, it is obvious that in the actual production process of the existing technology, due to the inability to cut the edge of the belt, the belt can only be discarded. Content of the Utility Model

Specifically, the trimming base 73 is assembled and connected to the U-shaped limiting plate 61 through an adjusting structure; the adjusting structure includes a fixed connecting rod fixedly connected to the rear side wall of the trimming base 73, a sliding sleeve 74 fixedly connected to the fixed connecting rod and slidably connected to the U-shaped limiting plate 61, and a plurality of locking screw rods 741 are threadedly connected to the sliding sleeve 74 (the locking screw rods 741 are pressed and locked on the U-shaped limiting plate 61).

[0069] During the working process, loosen the locking screw 741, slide the sliding sleeve 74 on the U-shaped limit plate 61 to adjust the distance between the two cutting machines. After adjustment, lock the locking screw 741 to position the edge cutting seat 73, and then, during the working process, cut the belt into different width sizes according to actual needs.
