Description

Technical Field

[0001] The utility model relates to the technical field of belt conveying equipment, in particular to a PLC-controlled self-aligning roller for a belt conveyor. Background Art

[0002] Belt conveyor equipment is a kind of transmission equipment commonly used in mining, port, metallurgy, lifting and transportation industries in the field of heavy machinery. It is generally composed of a belt that can continuously carry heavy objects and several rollers. The rotation of the roller drives the belt to move, and then the goods or objects carried on the belt are transmitted to the destination. The roller is an important component of the belt conveyor equipment. The function of the roller is to support the weight of the conveyor belt and materials. During the operation of the belt conveyor equipment, the tension on both sides of the conveyor belt is inconsistent or the material is not centered, which causes the material on the cross section of the conveyor belt to deviate, resulting in the conveyor belt to deviate. When the conveyor belt deviates seriously, the conveyor belt will be damaged. Therefore, it is necessary to install corresponding self-aligning rollers to ensure the stable operation of the conveyor belt and play a role in centering and alignment.

[0003] After the existing self-aligning rollers are installed, the staff needs to manually adjust the side rollers to the appropriate angle, which makes the staff's workload large and the device operation more complicated. At the same time, the self-aligning rollers have no buffering function, and long-term use makes the side rollers easy to be damaged. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a self-aligning roller controlled by PLC for a belt conveyor.

[0009] Furthermore, a protective shell is fixedly connected to the two fixing blocks, and the two protective shells are respectively matched with the two servo motors.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The user installs the device to the specified position so that the support roller contacts the lower end of the belt of the belt conveyor. At this time, the servo motor starts to work, and the side roller rotates to a suitable angle so that the side roller supports the side of the belt, realizing automatic adjustment of the angle of the side roller. Manual adjustment by the staff is not required, which improves the portability of the device. The two ends of the side roller apply an axial force of squeezing the middle to the belt, making it difficult for the belt to deviate. When the tension on both sides of the belt is inconsistent or the material is not centered and causes the belt to deviate, the servo motor starts to work, making the inclination angle of the side roller at one end of the belt deviate larger and the angle of the side roller at the other end smaller, so that the force on both sides of the belt will gradually be consistent, thereby preventing the belt from deviating.

[0015] 2. The buffer spring can buffer the fixed block so that the side roller can swing slightly, avoiding damage to the side roller due to factors such as the weight of the material and speed, thereby extending the service life of the side roller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-Figure 3 As shown, the embodiment of the utility model proposes a PLC-controlled self-aligning roller for a belt conveyor, comprising:

[0022] A support plate 1 is provided with a working groove, and fixed plates 2 are fixedly connected on both sides of the support plate 1. Multiple bolts 3 are slidably penetrated on the two fixed plates 2, which are convenient for users to fix the fixed plates 2. The ends of the two fixed plates 2 away from the supporting rollers 5 are provided with anti-slip patterns, which improve the friction between the fixed plates 2 and the fixed platform and the stability of the device. Two connecting plates 4 are fixedly connected to the upper end surface of the support plate 1, and the two connecting plates 4 are rotatably connected with the supporting rollers 5. Two fixed blocks 6 are rotatably connected to the inner wall of the working groove, and two buffer assemblies are provided on the inner wall of the working groove, and the two buffer assemblies are respectively arranged on the two fixed blocks 6; anti-deviation assembly; the anti-deviation assembly includes two centering mechanisms;

[0023] The centering mechanism includes a rotating groove 7 arranged on the fixed block 6, and a worm wheel 8 and a worm 9 are rotatably connected on the inner wall of the rotating groove 7, and the worm wheel 8 and the worm 9 are meshingly arranged. A rotating cavity 10 is arranged on the fixed block 6, and a first bevel gear 11 and a second bevel gear 12 are rotatably connected on the inner wall of the rotating cavity 10, and the first bevel gear 11 and the second bevel gear 12 are meshingly arranged. A connecting rod is rotatably passed through the fixed block 6, and the two ends of the connecting rod are respectively fixedly connected to the second bevel gear 12 and the worm 9, and two rotating rods are rotatably passed through the fixed block 6, and the two rotating rods are fixedly connected to the worm wheel 8, and the two rotating rods are connected to an adjusting plate 13, and two bearing plates are fixedly connected to the two adjusting plates 13;

[0024] The two bearing plates are connected to the side rollers 14 for common rotation, and a servo motor 15 is fixedly connected to one side wall of the fixed block 6. The output end of the servo motor 15 rotates through the fixed block 6 and is fixedly connected to the first bevel gear 11. The two fixed blocks 6 are fixedly connected with protective shells 19, and the two protective shells 19 are respectively matched with the two servo motors 15. The protective shells 19 can protect the servo motors 15 and prevent the servo motors 15 from being damaged by external interference. The support roller 5 and the two side rollers 14 are provided with anti-slip pads to improve the friction between the belt and the support roller 5 and the side rollers 14 to prevent the belt from easily running off the track. The buffer assembly includes two vertical plates 16 fixedly connected to the inner wall of the working groove, and the two vertical plates 16 are both inclined. One end of the fixed block 6 is fixedly connected to the limiting plate 17, and the two vertical plates 16 are fixedly connected with buffer springs 18.

[0025] The detailed working process of the utility model is as follows:

[0026] The user places the device at the designated installation position, and then uses the bolts 3 to fix the support plate 1 on the fixed platform, so that the support roller 5 contacts the lower end of the belt of the belt conveyor. At this time, the servo motor 15 starts to work, and the output end of the servo motor 15 drives the first bevel gear 11 to rotate, and the first bevel gear 11 drives the second bevel gear 12 to rotate. The connecting rod on the second bevel gear 12 drives the worm 9 to rotate, and the worm 9 makes the worm wheel 8 rotate in the rotating groove 7. The rotating rod on the worm wheel 8 drives the adjusting plate 13 to rotate, so that the side roller 14 rotates to a suitable angle. The side roller 14 supports the side of the belt, and realizes automatic adjustment of the angle of the side roller 14. Manual adjustment is not required by the staff, which improves the portability of the device. The two ends of the side rollers 14 apply an axial force of squeezing the middle to the belt, so that the belt is not easy to deviate. When the tension on both sides of the belt is inconsistent or the material is not centered and causes the belt to deviate, the servo motor 15 starts to work, making the inclination angle of the side roller 14 at one end of the belt deviate larger, and the angle of the side roller 14 at the other end smaller, so that the forces on both sides of the belt will gradually become consistent, and the raised belt will slowly reset, thereby preventing the belt from deviating. When the belt is conveying items, the buffer spring 18 can buffer the fixed block 6, so that the side roller 14 can swing slightly, avoiding damage to the side roller 14 due to factors such as the weight of the material and speed, thereby extending the service life of the side roller 14.
