Description

Technical Field

[0001] The utility model relates to the technical field of rubber coating for coal conveying belts, and specifically to a new rubber coating device for rollers. Background Technique

[0002] The rubber plate is a sheet product with a certain thickness and a large area, which is made of rubber as the main material and vulcanized. Its main function when used for rubber coating on the roller is to enhance the friction between the roller and the belt, thereby effectively reducing situations such as slipping and deviation of the belt during conveying.

[0003] In the existing patent with the application number CN 202322799115.9, a new rubber coating device for a coal conveying belt roller is disclosed. By setting a limit adjustment device to limit the position of the belt during rubber coating on the rubber sheet. At the same time, the limit adjustment device is also provided with an adjustable distance guide groove and an adjustable distance bolt that can adjust the distance, and can be adjusted adaptively for belts of different widths. However, during the adjustment process of a group of limit discs, only individual adjustment can be carried out through the adjustable distance bolt, and a group of limit discs cannot achieve synchronous adjustment, resulting in the phenomenon that the conveyor belt is prone to position deviation, affecting the normal use of the coal conveying belt.

DETAILED DESCRIPTION OF THE INVENTION

[0021] The following specifically describes the utility model with reference to the drawings, as Figures 1-5As shown: A new type of rubber coating device for a drum, including a drum 1 and roller shafts 2 fixedly installed at both ends of the drum 1. Synchronous adjustment limit mechanisms are provided on both sides of the drum 1. The synchronous adjustment limit mechanism includes two sets of opposite trapezoidal grooves 3, a set of rotating rods 4, two sets of opposite external threads 5, two sets of opposite sliding nuts 6, two sets of opposite trapezoidal sliders 7, and two sets of opposite limit discs 8. Two sets of opposite trapezoidal grooves 3 are opened at both ends inside the drum 1. A set of rotating rods 4 is movably inserted into the two sets of opposite trapezoidal grooves 3. Two sets of opposite external threads 5 are tapped on both ends of the outer surface of a set of rotating rods 4. Two sets of opposite sliding nuts 6 are movably sleeved on the two sets of opposite external threads 5. Two sets of opposite trapezoidal sliders 7 are installed outside the two sets of opposite sliding nuts 6. Two sets of opposite limit discs 8 are installed outside the two sets of opposite trapezoidal sliders 7. Mounting ring plates 9 are respectively installed at the ends of the drum 1. A circular hole 10 corresponding to a set of rotating rods 4 is opened on the right mounting ring plate 9. Outer hexagonal heads 11 are respectively installed at the right ends of a set of rotating rods 4. The two sets of opposite limit discs 8 fit together with each other. An inner cavity 12 corresponding to a set of rotating rods 4 is opened inside the drum 1. The outer surface of the drum 1 is wrapped with rubber 13, and a conveyor belt 14 is sleeved on the rubber 13.

[0022] Working principle of this implementation: The two sets of opposite trapezoidal grooves 3 are not covered with rubber. During use, the user first sleeved the conveyor belt 14 outside the rubber 13.
