Description

Technical Field

[0001] The present invention relates to the technical field of electric rollers, and particularly relates to an energy-efficient electric roller. Background Art

[0002] An energy-efficient electric roller is an electric roller device that integrates components such as a motor, a reducer, roller bearings, and a housing. It is mainly used for the drive system of conveyor belts and is widely used in material transportation in industries such as mining, metallurgy, coal, building materials, and logistics.

[0003] There are various existing electric rollers. For example, an energy-efficient electric roller disclosed in CN215973511U can effectively drive the conveyor belt to transport goods. However, when dealing with goods of different weights, there is usually no effective way to adjust the friction between the electric roller and the conveyor belt in the existing electric rollers. When transporting light-weight goods on the conveyor belt, excessive friction will exacerbate the wear of the conveyor belt. When transporting heavy-weight goods on the conveyor belt, too little friction may cause the heavy objects to slide or be unstable on the conveyor belt. Using an electric roller that cannot effectively adjust the friction for a long time may lead to increased wear of the conveyor belt, unstable goods, reduced transportation efficiency, increased load on the electric roller and the drive system, and even pose safety hazards. In addition, improper friction will also increase the 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. Summary of the Invention

[0004] Aiming at the above-mentioned drawbacks of the existing technology, the present invention provides an energy-efficient electric roller, which can effectively solve the problem that there is no effective way to handle the friction between the electric roller and the conveyor belt when transporting different goods in the existing technology.

[0013] Preferably, a support frame is fixedly installed at the upper end of the L-shaped fixing frame. An L-shaped bearing rod is fixedly installed at the upper end of the support frame. A turntable is rotatably installed on the side of the L-shaped bearing rod close to the support frame. A rotating rod is rotatably installed on one side of the turntable. A rotational speed detection element is fixedly installed on the side of the support frame close to the turntable. The rotational speed detection element is electrically connected to the controller.

[0014] Preferably, a driving assembly is further included. The driving assembly includes two rotating shafts rotatably installed on both sides of the support base and at a lower position. A toothed disc is fixedly installed at the opposite ends of the two rotating shafts. A conical helical tooth surface is formed on one side of the toothed disc. Two fixing plates are fixedly installed at the inner bottom end of the support base. A reciprocating lead screw is rotatably installed in the two fixing plates. A conical tooth head is fixedly installed at the end of the reciprocating lead screw close to the toothed disc. The conical tooth head meshes with the conical helical tooth surface. A T-shaped moving plate is sleeved on the outer wall of the reciprocating lead screw. A U-shaped connecting rod is fixedly installed at the lower position on one side of the T-shaped moving plate.

[0015] Preferably, a bearing box is fixedly installed on the lower end surface of the support base. Two support columns are fixedly installed on both sides of the bearing box. At the opposite ends of the two support columns, an air injection cylinder is fixedly installed. A slide plate is hermetically and slidably installed in the air injection cylinder.

An air outlet is communicated with a position near the lower part of one side of the lifting box.

[0017] The technical solution provided by the present invention has the following beneficial effects compared with the known prior art:

[0018] First, through the elastic cover arranged on the outer wall of the cylinder body, when the friction force between the cylinder body and the conveyor belt becomes small, the fan is driven to rotate by opening the rotary drive member. The rotating fan will rotate out the air in the air inlet and outlet cylinder outward in the air inlet and outlet cylinder, reducing the air pressure in the air inlet and outlet cylinder. Then, the air in the gap between the elastic cover and the cylinder body is extracted through the hollow connecting shaft, the air delivery pipe, the air inlet cover and the air inlet holes, causing the elastic cover to contract on the outer surface of the cylinder body. The contracted elastic cover will fit on the outer surface of the cylinder body and imprint the rack arranged on the outer surface of the cylinder body. When the air between the elastic cover and the cylinder body is completely extracted, the elastic cover will completely imprint the rack arranged on the outer surface of the cylinder body. In this way, when the cylinder body is in frictional transmission with the conveyor belt, the friction force is increased through the elastic cover with the imprinted rack, so as to drive the conveyor belt to convey stably;

[0019] The air between the elastic cover and the cylinder body can be adjusted according to the weight of the goods carried by the conveyor belt, so that the elastic cover imprints the shape of the rack to different degrees, increasing the friction force between the cylinder body and the conveyor belt. The arranged elastic cover can effectively reduce the friction loss between the cylinder body and the conveyor belt.

[0020] Second, when different goods are carried on the conveyor belt and the elastic cover is fully contracted and attached to the outer surface of the cylinder body and the rack is engraved, and the conveyor belt with a heavier load still cannot be conveyed, resistance will be generated when the cylinder body rubs against the conveyor belt. 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 conveyed into the lifting box and then sprayed out from the air outlet. The inner diameter of the connecting pipe is larger than that of the air outlet, and an air volume difference will be generated when flowing in the lifting box. The generated air volume difference will increase the air pressure in the lifting box. The increased air pressure will push the lifting plate to slide upward in the lifting box and stretch the second spring. The rising lifting plate will drive the lifting rod and the driving roller to rise together. The driving roller will cooperate with the cylinder body to clamp the conveyor belt between them. When the conveyor belt is conveyed at the upper end of the cylinder body, the arranged driving roller and the cylinder body will press the lower part of the conveyor belt upward, increasing the friction between the conveyor belt and the roller parts, thereby increasing the moving efficiency of the conveyor belt.

The elastic cover 209 can be made of existing highly wear-resistant rubber. The highly wear-resistant rubber not only has good elasticity, but also can maintain a long service life during frequent reciprocating movements. It has strong resistance to friction, impact and fatigue. Therefore, it is particularly suitable for long-term reciprocating use. The elastic cover 209 expands or contracts on the outer wall of the cylinder body 201. When the elastic cover 209 contracts, the rack teeth 204 are engraved to increase the friction with the conveyor belt. When it expands, the outer wall of the elastic cover 209 is smooth to reduce the friction;

[0036] Detection assembly 3, used to detect the conveyor efficiency of the conveyor belt.

[0037] Refer to Figures 2 to 4 , oval notches are provided on both sides of the support base 1. A motor 208 is fixedly installed on one side of the support base 1. The output end of the motor 208 is fixedly connected to the cylinder body 201. Two tooth rings 202 are fixedly installed on the outer walls at both ends of the cylinder body 201.

Air inlet holes 205 are circumferentially arrayed in the inner circumference of one of the tooth rings 202. An air inlet cover 206 is fixedly installed at the end of the cylinder body 201 away from the motor 208. A hollow connecting shaft 210 is coaxially fixedly installed at the end of the cylinder body 201 away from the motor 208. The hollow connecting shaft 210 is communicated with the air inlet cover 206 through an air delivery pipe 214. An L-shaped fixing frame 207 is fixedly installed on the outer wall of the hollow connecting shaft 210. The hollow connecting shaft 210 is slidably connected with the oval notch. An air inlet and outlet cylinder 211 is fixedly installed on one side of the L-shaped fixing frame 207. A support 213 is fixedly installed on the inner wall of the air inlet and outlet cylinder 211.

A solenoid valve 212 is embedded at one end of the air inlet and outlet cylinder 211.

The rotational speed detection element 305 can be used with an existing Hall rotational speed sensor. The Hall rotational speed sensor is a commonly used sensor for measuring the rotational speed of an object. Since the Hall rotational speed sensor needs to use a magnetic material to detect a rotating object, the provided rotating rod 304 can be made of a permanent magnetic material to facilitate detection by the Hall rotational speed sensor.

An air outlet 504 is communicated with one side of the lifting box 501 at a lower position.

[0041] The working principle of the present invention is as follows:

[0042] First, detect 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 heavy goods, the friction between the cylinder 201 and the conveyor belt needs to be increased, so as to effectively drive the conveyor belt to move. When the conveyor belts carrying different goods are driven by the cylinder 201 for transmission, the turntable 303 provided contacts the surface of the conveyor belt. When the conveyor belt moves, it will drive the turntable 303 to rotate together. The rotating turntable 303 will drive the rotating rod 304 to rotate together. The rotating rod 304 will detect the rotation speed through the rotation speed detection element 305. When the conveyor belt transports goods of different weights, the moving speed of the transported goods should be kept consistent, and the friction between the conveyor belt and the cylinder 201 when carrying different goods needs to be increased or decreased according to the weight of the goods. Through the setting of the rotation speed detection element 305, the rotation speed detection element 305 can indirectly detect the moving speed of the conveyor belt when it is driven by the cylinder 201 to move through the rotating turntable 303;

[0043] Second, adjust the friction: When the conveyor belt is carrying heavy goods, if the friction between the conveyor belt and the cylinder 201 is small, 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. Through the set rotation speed detection element 305, it is detected that the rotation speed of the rotating rod 304 slows down, 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 supply to the electromagnetic coil in the solenoid valve 212 to open the solenoid valve 212. At the same time, it will control the power supply to the rotary drive 216 to open the rotary drive 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, reducing the air pressure in the air inlet and outlet cylinder 211. After the air pressure in the air inlet and outlet cylinder 211 is further reduced, it will extract the air in the gap between the elastic cover 209 and the cylinder 201 through the hollow connecting shaft 210, the air pipe 214, the air inlet cover 206 and the air inlet hole 205, and discharge it outward through the solenoid valve 212, causing the elastic cover 209 to contract on the outer surface of the cylinder 201. The contracted elastic cover 209 will fit on the outer surface of the cylinder 201 and imprint the rack 204 provided 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 will completely imprint the rack 204 provided on the outer surface of the cylinder 201. In this way, when the cylinder 201 is in frictional transmission with the conveyor belt, the friction is increased through the elastic cover 209 imprinted with the rack 204 (the elastic cover 209 completely imprints the rack, so when the cylinder 201 is in frictional transmission with the conveyor belt, the contact roughness with the conveyor belt is increased through the elastic cover 209 imprinted with the rack, thereby increasing the friction), so as to drive the conveyor belt to convey stably;

[0044] It should be noted that when the conveyor belt is carrying light goods, the rotary drive 216 drives the fan 215 to rotate in the reverse direction to deliver air to the gap between the elastic cover 209 and the cylinder 201, causing the elastic cover 209 to expand. The outer surface of the expanded elastic cover 209 will become smooth, and the friction with the conveyor belt will decrease, so as to smoothly drive the conveyor belt to move (the fan 215 can be replaced according to the different goods transported. For example, a centrifugal fan and an axial flow fan can be used. There may be a certain degree of air leakage in the actual system. Therefore, a certain margin should be reserved when selecting the air volume of the fan. Generally, an increase of 10% - 20% in air volume can be considered to compensate for the possible air leakage loss to ensure the effective expansion and contraction functions of the elastic cover under various working conditions);

[0045] The air between the elastic cover 209 and the cylinder body 201 can be adjusted by the weight of the goods carried by the conveyor belt, so that the elastic cover 209 can imprint the shape of the rack 204 to different degrees, thereby increasing the friction force between the cylinder body 201 and the conveyor belt. The set elastic cover 209 can effectively reduce the friction loss between the cylinder body 201 and the conveyor belt;

[0046] Third, transporting heavier goods: When different goods are carried on the conveyor belt and the elastic cover 209 is completely shrunk and attached to the outer surface of the cylinder body 201 and imprints the rack 204 as described above, and the conveyor belt with a heavier load still cannot be transported, the cylinder body 201 will generate resistance when rubbing against the conveyor belt. The cylinder body 201 will rotate and displace by sliding in the elliptical notch. The cylinder body 201 will slide above the auxiliary drive assembly 5. At this time, the rotating cylinder body 201 will drive the toothed ring 202 and the inclined plane ring 203 to rotate together. The rotating toothed ring 202 will engage with the toothed disc 402 and rotate. The rotating toothed disc 402 will drive the bevel gear head 404 and the reciprocating lead screw 405 to rotate together. The rotating reciprocating lead screw 405 will drive the T-shaped moving plate 406 to reciprocate on its outer wall. The reciprocating T-shaped moving plate 406 will drive the U-shaped connecting rod 407 to reciprocate together. When the U-shaped connecting rod 407 reciprocates, it will drive the sliding plate 409 to reciprocate inside the air injection cylinder 408. When the sliding plate 409 slides into the inner wall of the air injection cylinder 408, the air inside the air injection cylinder 408 will be squeezed into the connecting pipe 411 through the second one-way valve. When the sliding plate 409 slides out of the air injection cylinder 408, the outside air will flow into the air injection cylinder 408 through the first one-way valve 410;

[0047] The air entering the connecting pipe 411 will be transported into the lifting box 501 and then sprayed out 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 flowing in the lifting box 501, an air volume difference will be generated. The generated air volume difference will increase the air pressure in the lifting box 501. The increased air pressure will push the lifting plate 503 to slide and rise 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 body 201 to clamp the conveyor belt between them. The friction force between the transmission roller 506 and the conveyor belt is increased through the set notch 508. During the process of the inclined plane disc 507 rising with the transmission roller 506, it will frictionally transmit with the inclined plane ring 203, thereby driving the transmission roller 506 to rotate together. In this way, when the conveyor belt is transported above the cylinder body 201, the set transmission roller 506 and the cylinder body 201 will press the lower part of the conveyor belt below the cylinder body 201 upward, increasing the friction force between the conveyor belt and the roller parts, thereby increasing the moving efficiency of the conveyor belt.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
