Description

Technical Field

[0001] The invention relates to the technical field of electric rollers, and in particular to a high-efficiency and energy-saving electric roller. Background Art

[0002] The high-efficiency and energy-saving electric roller is an electric roller equipment that integrates components such as motor, reducer, roller bearing and shell. It is mainly used in the drive system of the conveyor belt and is widely used in material transportation in mining, metallurgy, coal, building materials, logistics and other industries.

[0003] There are many types of existing electric rollers, such as a high-efficiency and energy-saving electric roller disclosed as CN215973511U. This device can effectively drive the conveyor belt to transport goods. However, when the existing electric rollers handle goods of different weights, there is usually no effective way to adjust the friction between the electric roller and the conveyor belt. When the conveyor belt is transporting lighter goods, excessive friction will aggravate the wear of the conveyor belt. When the conveyor belt is transporting heavier goods, too little friction may cause the heavy objects to slide on the conveyor belt or become unstable. Long-term use of electric rollers that cannot effectively adjust the friction may cause increased wear of the conveyor belt, unstable goods, reduced conveying efficiency, and increased load on the electric roller and drive system, and even bring safety hazards. In addition, improper friction will also increase maintenance and management costs and shorten the service life of the equipment. Therefore, in order to improve efficiency, ensure safety and reduce operation and maintenance costs, it is recommended to adopt a system with adjustable friction to better meet the transportation needs of goods of different weights.

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: First, by means of an elastic cover arranged on the outer wall of the cylinder, when the friction between the cylinder and the conveyor belt becomes smaller, the fan is driven to rotate by opening the rotary drive member, and the rotating fan rotates outward in the air inlet and outlet cylinder to discharge the air in the air inlet and outlet cylinder, so that the air pressure in the air inlet and outlet cylinder is reduced, and the air in the gap between the elastic cover and the cylinder is extracted through the hollow connecting shaft, the air delivery pipe, the air inlet cover and the air inlet hole, so that the elastic cover shrinks on the outer surface of the cylinder, and the shrunken elastic cover will fit on the outer surface of the cylinder and engrave the rack arranged on the outer surface of the cylinder. When the air between the elastic cover and the cylinder is completely extracted, the elastic cover will completely engrave the rack arranged on the outer surface of the cylinder. In this way, when the cylinder is frictionally transmitted with the conveyor belt, the friction is increased by the elastic cover engraved with the rack, so as to drive the conveyor belt to transport stably; The air between the elastic cover and the cylinder can be adjusted by the weight of the goods carried by the conveyor belt, so that the elastic cover can engrave the shape of the rack to varying degrees to increase the friction between the cylinder and the conveyor belt. The set elastic cover can effectively reduce the friction loss between the cylinder and the conveyor belt.

[0014] Second, when the conveyor belt carries different goods and the elastic cover is completely contracted and fits the outer surface of the cylinder and prints the rack, it is still unable to transport the conveyor belt with a heavier load. The cylinder will generate resistance when rubbing against the conveyor belt, and the outside air will be driven to be injected into the air injection cylinder through the first one-way valve. The air entering the connecting pipe will be transported to the lifting box and then sprayed out from the air outlet. The inner diameter of the connecting pipe is larger than the inner diameter of the air outlet. When flowing in the lifting box, a gas volume difference will be generated. The generated gas volume difference will increase the air pressure in the lifting box. The increased air pressure will push the lifting plate to slide and rise in the lifting box and stretch the second spring. The rising lifting plate will drive the lifting rod and the transmission roller to rise together. The transmission roller will cooperate with the cylinder to clamp the conveyor belt between them. When the conveyor belt is transported at the upper end of the cylinder, the arranged transmission roller and the cylinder will press the lower part of the conveyor belt upward at the cylinder, increase the friction between the conveyor belt and the roller, thereby increasing the movement efficiency of the conveyor belt.

[0025] The working principle of the present invention is as follows: First, detecting the moving speed of the conveyor belt: by turning on the motor 208 to drive the cylinder 201 to rotate, the rotating cylinder 201 will drive the conveyor belt to move. When the conveyor belt carries heavier goods, the friction between the cylinder 201 and the conveyor belt needs to be increased, so that the conveyor belt can be effectively driven to move. When the conveyor belt carrying different goods is driven by the cylinder 201 for transmission, the provided turntable 303 contacts the surface of the conveyor belt. When the conveyor belt is displaced, the turntable 303 will be driven to rotate together. The rotating turntable 303 will drive the rotating rod 304 to rotate together. The rotating rotating rod 304 will detect the speed through the speed detection element 305. When the conveyor belt transports goods of different weights, the moving speed of the transported goods should be consistent. When the conveyor belt carries different goods, the friction between the conveyor belt and the cylinder 201 needs to be increased or decreased according to the weight of the goods. Through the setting of the speed detection element 305, the speed detection element 305 can indirectly detect the moving speed of the conveyor belt when it is driven by the cylinder 201 through the rotating turntable 303; Second, adjusting the friction: when the conveyor belt carries heavier goods, the friction between the conveyor belt and the cylinder 201 is smaller, the moving speed of the conveyor belt will slow down, and the turntable 303 and the rotating rod 304 will also be driven to slow down the rotation speed. The rotation speed detection element 305 is set to detect the slowdown of the rotation speed of the rotating rod 304, and the controller electrically connected to the rack 204 will determine that the friction between the conveyor belt and the cylinder 201 is too small. The controller will control the power input to the electromagnetic coil in the electromagnetic valve 212 to open the electromagnetic valve 212, and at the same time control the power input to the rotating drive member 216 to open the rotating drive member 216 to drive the fan 215 to rotate. The rotating fan 215 will rotate outward in the air inlet and outlet cylinder 211 to discharge the air in the air inlet and outlet cylinder 211, so that the air pressure in the air inlet and outlet cylinder 211 is reduced. After the air pressure in the air inlet and outlet cylinder 211 is reduced again, it will pass through the hollow connecting shaft 210 , the air supply pipe 214, the air inlet cover 206 and the air inlet hole 205 extract the air in the gap between the elastic cover 209 and the cylinder 201, and discharge it outward through the electromagnetic valve 212, so that the elastic cover 209 shrinks on the outer surface of the cylinder 201. The shrinking elastic cover 209 will fit on the outer surface of the cylinder 201 and engrave the rack 204 set on the outer surface of the cylinder 201. When the air between the elastic cover 209 and the cylinder 201 is completely extracted, the elastic cover 209 shrinks. 9 will completely engrave the rack 204 set on the outer surface of the cylinder 201, so that when the cylinder 201 is frictionally transmitted with the conveyor belt, the elastic cover 209 engraved with the rack 204 increases the friction force (the elastic cover 209 completely engraves the rack, so that when the cylinder 201 is frictionally transmitted with the conveyor belt, the elastic cover 209 engraved with the rack increases the contact roughness with the conveyor belt, thereby increasing the friction force), so as to drive the conveyor belt to transport stably; It should be noted that when the conveyor belt carries light goods, the fan 215 is driven to rotate in the opposite direction by the above-mentioned rotating drive member 216, and air is delivered to the gap between the elastic cover 209 and the cylinder 201, so that the elastic cover 209 expands, and the outer surface of the expanded elastic cover 209 becomes smooth, and the friction between the elastic cover 209 and the conveyor belt is reduced, so as to drive the conveyor belt to move smoothly (the fan 215 can be replaced according to the selection of different goods to be transported, for example, a centrifugal fan and an axial flow fan are used. There may be a certain degree of air leakage in the actual system, so a certain margin should be reserved when selecting the air volume of the fan. Generally, it can be considered to increase the air volume by 10% - 20% to compensate for possible air leakage losses, so as to ensure that the expansion and contraction functions of the elastic cover can be effectively realized under various working conditions); The air between the elastic cover 209 and the cylinder 201 can be adjusted by the weight of the goods carried by the conveyor belt, so that the elastic cover 209 can engrave the shape of the rack 204 to varying degrees to increase the friction between the cylinder 201 and the conveyor belt. The elastic cover 209 can effectively reduce the friction loss between the cylinder 201 and the conveyor belt. Third, transporting heavier goods: When the conveyor belt carries different goods, and the elastic cover 209 is completely shrunk to fit the outer surface of the cylinder 201 and the rack 204 is engraved as described above, but the conveyor belt with a heavier load cannot be transported, the cylinder 201 will generate resistance when rubbing against the conveyor belt, and the cylinder 201 will rotate and move by sliding in the elliptical groove of the cylinder 201. The cylinder 201 will slide to the top of the auxiliary transmission component 5. At this time, the rotating cylinder 201 will drive the gear ring 202 and the bevel ring 203 to rotate together, and the rotating gear ring 202 will mesh with the toothed disc 402 to rotate, and the rotating toothed disc 402 will rotate. The bevel gear head 404 is driven to rotate together with the reciprocating screw 405, and the rotating reciprocating screw 405 drives the T-shaped movable plate 406 to reciprocate on its outer wall, and the reciprocating T-shaped movable plate 406 drives the U-shaped connecting rod 407 to reciprocate together, and when the U-shaped connecting rod 407 reciprocates, it drives the slide plate 409 to slide back and forth on the inner wall of the gas injection cylinder 408, and when the slide plate 409 slides toward the inner wall of the gas injection cylinder 408, the air inside the gas injection cylinder 408 is squeezed into the connecting pipe 411 through the second one-way valve, and when the slide plate 409 slides outside the gas injection cylinder 408, the outside air flows into the gas injection cylinder 408 through the first one-way valve 410; The air entering the connecting pipe 411 will be transported to the lifting box 501 and then ejected outward from the air outlet 504. The inner diameter of the connecting pipe 411 is larger than the inner diameter of the air outlet 504. When the air flows in the lifting box 501, a gas volume difference will be generated. The generated gas volume difference will increase the air pressure in the lifting box 501. The increased air pressure will push the lifting plate 503 to slide up in the lifting box 501 and stretch the second spring 505. The rising lifting plate 503 will drive the lifting rod 502 and the transmission roller 506 to rise together. The transmission roller 506 will cooperate with the cylinder The body 201 clamps the conveyor belt therebetween, and the friction between the drive roller 506 and the conveyor belt is increased by the arranged notch 508, and the inclined disk 507 will rub and transmit with the inclined ring 203 as the drive roller 506 rises, thereby driving the drive roller 506 to rotate together, so that when the conveyor belt is transported at the upper end of the cylinder 201, the arranged drive roller 506 and the cylinder 201 will press the lower part of the conveyor belt upwards, increase the friction between the conveyor belt and the roller, and thus increase the moving efficiency of the conveyor belt.
