Pneumatic automatic high-strength conveying belt cutting machine

Abstract

A pneumatic automatic high-strength conveyor belt cutting machine comprises a roller runway, a roller, a roller support, a carrier roller, a lower blade, an upper blade, a pneumatic motor, a speed reducer, a housing, an upper fixing frame, a lower fixing frame and a handle. Compressed air enters the pneumatic motor as a power source and drives the upper blade to rotate after being decelerated by the speed reducer to amplify torque, and the steel wire rope core embedded conveying belt is hooked by the upper blade to continuously move backwards and is matched with the lower blade to cut the conveying belt.

Description

Technical Field

[0001] The utility model relates to a pneumatic automatic high-strength conveyor belt cutting machine, which is used for cutting conveyor belts, in particular to steel wire rope core embedded conveyor belts used in underground coal mines. Background Art

[0002] In the mine, ordinary grinding machines are used to cut the conveyor belt with embedded steel cord core. The rubber is heated and smoke is billowing when cutting, and the steel cord core is cut with sparks. In the mine, because there can be no sparks, the rubber part is manually peeled off and then the steel cord core is cut with pliers. These two operations are not only time-consuming and labor-intensive, but also pollute the environment. Utility Model Content

[0003] The utility model aims to provide a pneumatic automatic high-strength conveyor belt cutting machine which relies on compressed air as a power source, which can fully utilize the surplus compressed air underground, save energy and reduce waste.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a pneumatic automatic high-strength conveyor belt cutting machine including a roller runway, a roller, a roller bracket, a roller, a lower blade, an upper blade, a pneumatic motor, a reducer, a cover, an upper fixing frame, a lower fixing frame, and a handle.

[0005] The cutting process of the utility model is as follows: compressed air enters the pneumatic motor as a power source, and drives the upper blade to rotate after being decelerated and amplified by the reducer. The conveyor belt embedded with steel wire core is hooked by the upper blade and moves backward continuously, and cooperates with the lower blade to cut the conveyor belt.

[0006] The utility model has the advantages of utilizing the existing compressed air in the well as a power source, requiring no explosion-proof measures, and reducing the labor intensity of manual cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The utility model is described in detail below in conjunction with the accompanying drawings:

[0011] The utility model provides a pneumatic automatic high-strength conveyor belt cutting machine, which comprises a roller runway (1), a roller (2), a roller bracket (3), a roller (4), a lower blade (5), an upper blade (6), a pneumatic motor (7), a speed reducer (8), a cover shell (9), a handle (10), an upper fixing frame (11), and a lower fixing frame (12). The lower blade (5) is fixed inside the lower fixing frame (12), the roller (4) is fixed at the front end of the lower fixing frame (12), the upper blade (6) is installed on the upper part of the lower fixing frame (12) through the upper fixing frame (11), the pneumatic motor (7) drives the upper blade (6) to rotate by speed reduction through the speed reducer (8), the cover shell (9) is fixed on the upper part of the upper fixing frame (11) to cover the upper blade (6), the roller (2) is fixed to the lower end of the lower fixing frame (11) through the roller bracket (3), and travels on the roller runway (1).

[0012] The pneumatic motor (7) is connected to compressed air, and one end of the steel cord conveyor belt to be cut is pushed from the upper part of the roller (4) to the middle of the lower blade (5) and the upper blade (6). The handle (10) is grasped to push the cutter forward, and the compressed air enters the pneumatic motor (7), and drives the upper blade (6) to rotate through the reducer (8). After the upper blade (6) hooks the steel cord conveyor belt, the cutter moves forward on the roller runway (1) as it passes through the roller (2). The roller (4) supports the steel cord conveyor belt, and the upper blade (6) rotates continuously and cooperates with the lower blade (5) to cut the steel cord conveyor belt until the conveyor belt is cut.

[0013] The utility model drives the upper blade (6) to rotate and cut the embedded steel wire core conveyor belt through a pneumatic motor (7) and a speed reducer (8), thereby eliminating the need for manual cutting and saving time and effort. In addition, compressed air is used as a power source, explosion-proof technology is not required, and no sparks are generated when cutting the steel wire.
