Description

Technical Field

[0001] This utility model relates to the field of transmission and control correction technology, and in particular to a transmission and control rolling correction device. Background Technology

[0002] Belt conveyors are widely used in various bulk material conveying systems, and their safe and stable operation directly affects production operations. Belt misalignment is the most common fault in belt conveyors, necessitating the use of controlled rolling correction devices. In many continuous production processes, materials (such as paper and fabrics) often need to move precisely along a designated path. Due to equipment precision issues, changes in material characteristics, or external environmental influences, material deviations can occur, leading to decreased production quality or equipment malfunction.

[0003] However, existing belt conveyors suffer from severe material spillage during transport, or the belt edges are prone to wear, thus affecting production efficiency. When belt misalignment reaches a certain level, it also reduces the belt's service life and can cause significant economic losses in severe cases. Furthermore, the spillage process generates dust and coal dust, causing environmental pollution and requiring dust removal, increasing manual labor intensity. Coal dust and other pollutants can also harm workers' health. Belt misalignment can also cause uneven stress on key components of the conveyor, such as rollers and idlers, leading to abnormal damage. To address these problems, those skilled in the art have proposed a controlled rolling correction device to solve these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a transmission and control rolling correction device, which aims to improve the problems of serious spillage or easy wear of belt edges when conveying materials in existing belt conveyors, thereby affecting production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transmission-controlled rolling correction device, comprising a conveyor belt, a roller body installed at the bottom of the conveyor belt, front signal sensing switches installed on both sides of the conveyor belt, a miniature explosion-proof linear actuator installed at the bottom of the conveyor belt, a double-bearing rotating shaft bracket installed at the output end of the miniature explosion-proof linear actuator, a double-bearing rotating shaft roller group installed outside the double-bearing rotating shaft bracket, an upper-layer positioning bearing installed outside the double-bearing rotating shaft bracket, a lower-layer lifting bearing installed at the bottom of the double-bearing rotating shaft bracket, a dustproof cover installed outside the miniature explosion-proof linear actuator, a rotating arm installed outside the double-bearing rotating shaft bracket, and an adjustment rotating roller group installed at the top of the double-bearing rotating shaft bracket.

[0006] Furthermore, the rotating arm is connected to the control box via a signal line, and the signal line is connected to the front signal sensing switch via the control box.

[0007] Furthermore, the dual-bearing shaft bracket adopts a dual-bearing structure, with the upper locking bearing bearing the radial load and the lower supporting bearing adopting a tapered roller bearing to bear the axial load.

[0008] Furthermore, the miniature explosion-proof linear actuator is an electric linear actuator used to respond to signals emitted by a pre-signal sensing switch.

[0009] Furthermore, the front signal sensing switch is a contact sensing device used to sense belt deviation, and the signal line is used to transmit the signal to the control box, which is used to control the miniature explosion-proof linear actuator to adjust the position of the deviation-adjusting rotary idler group.

[0010] Furthermore, both the miniature explosion-proof linear actuator and the rotating arm are located inside a dustproof cover, and the inside of the dustproof cover is sealed.

[0011] Furthermore, the eccentricity-adjusting rotary idler group works in conjunction with the dual-bearing rotating shaft idler group and the miniature explosion-proof linear actuator to correct the conveyor belt deviation by adjusting the angle of the eccentricity-adjusting rotary idler group.

[0012] Furthermore, the control box is connected to a signal line, enabling analysis of the degree of deviation based on signals emitted by the pre-signal sensing switch.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the control box program continuously detects and adjusts the conveyor belt, enabling unattended operation and 24 / 7 operation unaffected by working conditions. It also detects the deviation of the conveyor belt and quickly provides feedback and adjustment based on the deviation amount, reducing damage to the belt conveyor equipment and spillage of transported materials.

[0015] 2. In this utility model, by adopting a double-bearing rotating idler frame structure, the structure is stable, the rotating shaft rotates freely, and there are bearing seat seals and grease lubrication, making the rotation flexible and stable and reliable for long-term use. In addition, the induction switch is divided into two levels, which can control the deviation of the conveyor belt within a very small range according to different deviation amounts, ensuring stable material conveying and normal operation of the equipment, and making the correction effect faster, better and more accurate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a controllable rolling correction device, including a conveyor belt 1, a roller body 2 installed at the bottom of the conveyor belt 1 for supporting the operation of the conveyor belt 1, front signal sensing switches 3 installed on both sides of the conveyor belt 1 for detecting whether the conveyor belt 1 deviates from the center position, a miniature explosion-proof linear actuator 7 provided at the bottom of the conveyor belt 1 for providing driving force, a double bearing shaft bracket 5 installed at the output end of the miniature explosion-proof linear actuator 7 for supporting the shaft, a double bearing shaft idler group 4 provided outside the double bearing shaft bracket 5, and a double bearing shaft idler group 4. The idler roller assembly 4 provides rotational support. An upper-level locking bearing 6 is installed on the outside of the double-bearing swivel bracket 5. The upper-level locking bearing 6 serves to fix and adjust the position of the double-bearing swivel bracket 5. A lower-level lifting bearing 8 is installed at the bottom of the double-bearing swivel bracket 5, which provides support. A dustproof cover 9 is installed on the outside of the miniature explosion-proof linear actuator 7, which effectively prevents dust. A rotating arm 10 is installed on the outside of the double-bearing swivel bracket 5. The rotating arm 10 is used to adjust the angle of the double-bearing swivel bracket 5. An adjustment rotating idler roller assembly 13 is installed on the top of the double-bearing swivel bracket 5. The adjustment rotating idler roller assembly 13 adjusts the offset direction of the conveyor belt 1 by rotation.

[0022] Reference Figure 1 and Figure 2The rotating arm 10 is connected to the control box 11 via signal line 12. Signal line 12 is connected to the front signal induction switch 3 via the control box 11. Signal line 12 transmits the signal from the front signal induction switch 3. The double-bearing shaft bracket 5 adopts a double-bearing structure, which enhances the load-bearing capacity and ensures stable operation of the equipment under high load. The upper positioning bearing 6 bears the radial load and provides support to prevent excessive displacement of the system due to radial pressure. The lower lifting bearing 8 adopts a tapered roller bearing to bear the axial load. The lower lifting bearing 8 can effectively bear the axial force and ensure the stability of the shaft bracket under force. The miniature explosion-proof linear actuator 7 is an electric linear actuator used to respond to the signal issued by the front signal induction switch 3. The miniature explosion-proof linear actuator 7 performs offset correction through precise electric control.

[0023] Reference Figure 1 and Figure 2 The front signal sensor switch 3 is a contact-type sensor used to sense the deviation of the conveyor belt 1. It senses the offset position of the conveyor belt 1 and provides real-time feedback signals. The signal line 12 is used to transmit the signal to the control box 11, ensuring stable signal transmission from the front signal sensor switch 3 to the control box 11. The control box 11 is used to control the miniature explosion-proof linear actuator 7 to adjust the position of the alignment roller assembly 13. The control box 11 precisely adjusts the system based on the signal feedback from the front signal sensor switch 3. The miniature explosion-proof linear actuator 7 and the rotating arm 10 are both housed inside the dustproof cover 9, which effectively blocks dust and impurities. The interior of the dustproof cover 9 is sealed to prevent external environmental influences. The alignment roller assembly 13 works in conjunction with the double-bearing rotating roller assembly 4 and the miniature explosion-proof linear actuator 7, adjusting the angle of the alignment roller assembly 13 to correct the deviation of the conveyor belt 1. The control box 11 is connected to the signal line 12, which can analyze the degree of deviation based on the signal emitted by the front signal sensing switch 3, and further finely adjust the correction process.

[0024] Working principle: When using this device, the position of the conveyor belt 1 is precisely adjusted by the cooperation of the front-mounted induction signal switch and the miniature explosion-proof linear actuator 7. The front-mounted induction signal switch is symmetrically installed on both sides of the belt conveyor. The induction signal switch can be contact type and has two signal settings, corresponding to slight deviation and severe deviation respectively. When the conveyor belt 1 deviates, the induction signal switch sends a corresponding signal according to the degree of deviation. The signal is transmitted to the control box 11 through the transmission line. The control box 11 analyzes the signal level and the direction of deviation and issues instructions to the miniature explosion-proof linear actuator 7 in a timely manner.

[0025] The miniature explosion-proof linear actuator 7 serves as the drive source, precisely controlling the rotation of the dual-bearing rotating shaft bracket 5, which in turn rotates the dual-bearing rotating shaft idler roller group 4 to a set angle. The rotation of the idler roller group generates a certain resistance, and this torque causes the conveyor belt 1 to adjust back to the correct path, achieving precise correction of conveyor belt 1's deviation. This device, through its efficient feedback mechanism and sensitive control system, can quickly respond to changes in the offset of the conveyor belt 1, ensuring the stability and safety of the conveyor belt 1's operation, while effectively avoiding potential sluggishness, jamming, and leakage problems that may occur in mechanical or hydraulic systems.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
