Description

Technical Field

[0001] This utility model relates to the field of material conveying device technology, and in particular to a conveyor belt drive device. Background Technology

[0002] A conveyor belt conveyor is a mechanical device that transports materials through continuous cyclic motion. It is widely used in industrial production, logistics transportation, mining, and other fields. The conveyor belt of the conveyor belt conveyor is driven by a conveyor belt drive device to ensure the smooth and stable movement of the conveyor belt.

[0003] In existing conveyor belt drive devices, roller mounting seats are located on both sides of the front end of the drive frame. The rollers are mounted on the roller mounting seats via bearing seats. Motors are located on both sides of the drive frame, and the motors are connected to the main shaft end of the rollers via reducers to achieve roller rotation, thereby driving the conveyor belt wound around the rollers. However, in existing conveyor belt drive devices, mounting rods extend outward from both sides of the roller mounting seats and are fixed thereon. The reducer is mounted on the mounting rods via a reducer base. Because the motor generates a large torque on the mounting rods when driving the rollers through the reducer, the mounting rods are prone to twisting or even breaking. The reducer base is not securely fixed, thus failing to ensure the stability of the reducer and motor, which affects the rotation of the rollers.

[0004] Meanwhile, in existing conveyor belt drive devices, the roller mounting seats on both sides are independent of each other. During installation, it is difficult to unify the front and rear positions of the two roller mounting seats, making it difficult to ensure that the bottom surfaces of the two bearing seats are on the same plane, which can easily lead to roller shaft breakage. Utility Model Content

[0005] To address the above shortcomings, this utility model provides a conveyor belt drive device that can solve the problem that the existing reducer base is not guaranteed to be fixed, which can easily lead to instability of the reducer and motor, thus affecting the rotation of the drum.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveyor belt drive device includes a drive frame, roller mounting seats located on both sides of the front end of the drive frame, and a roller located between the two roller mounting seats. Each of the two roller mounting seats has a bearing seat. The two ends of the main shaft of the roller are rotatably mounted on the roller mounting seats via the bearing seats. Each end of the main shaft of the roller is also connected to a motor via a reducer. The reducer has a reducer base, and a connector is provided on the reducer base. The connector has through holes extending through both sides. The roller mounting seats have reducer mounting seats, and the reducer mounting seats have two opposing limiting plates. The two limiting plates have through holes facing each other. The connector is located between the two limiting plates, and the through holes of the connector and the limiting plates are facing each other and a pin is inserted into one of them.

[0008] Furthermore, the reducer mounting base also includes a reducer mounting base base plate and an I-shaped mounting component. The reducer mounting base base plate is fastened to the roller mounting base by bolts. The I-shaped mounting component is fixedly installed on the reducer mounting base base plate. Two limiting plates are fixedly installed on the middle horizontal plate of the I-shaped mounting component and their ends are fixed to the two end vertical plates of the I-shaped mounting component.

[0009] Furthermore, a limiting block is fixedly provided at one end of the pin shaft, and the limiting block is fastened to the limiting plate on the same side by bolts.

[0010] Furthermore, a roller mounting bracket connector is fixedly connected between the two roller mounting brackets to make the two roller mounting brackets an integrated unit.

[0011] Furthermore, the drive frame is provided with sleeves extending forward and backward on both sides and a fixing plate located behind the sleeves. The fixing plate has a fixing plate through hole. The roller mounting base is provided with sliding members that match the sleeves. The end of the sliding member is fixedly provided with a screw. The sliding member is sleeved in the sleeve. The screw passes through the fixing plate through hole and the screw is tightened with adjusting nuts on both sides of the fixing plate.

[0012] Furthermore, locking screw holes are provided on both sides of the drive frame, and elongated holes extending forward and backward are provided on the roller mounting base. When the screw of the roller mounting base is fixed to the fixing plate of the drive frame by adjusting nut, the elongated holes are aligned with the locking screw holes, and adjusting bolts are screwed into the locking screw holes to lock the roller mounting base onto the drive frame.

[0013] Furthermore, a first transverse plate is fixedly arranged on both sides of the drive frame, and the locking screw hole is opened on the first transverse plate; a second transverse plate is fixedly arranged on the roller mounting base, and the elongated hole is opened on the second transverse plate; the first transverse plate and the second transverse plate are stacked on top of each other and fit together.

[0014] Furthermore, there are multiple locking screw holes, and the number of adjusting bolts and elongated holes is consistent with the number of locking screw holes, and they correspond one-to-one with the locking screw holes.

[0015] Furthermore, the main shaft of the roller is a one-piece through shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] The conveyor belt drive device of this utility model, by setting a reducer mounting base and a pin, with the pin supported by a limiting plate and the reducer mounting base fixed to the roller mounting base, ensures that the pin is not easily twisted, broken, or disconnected under the support and protection of the limiting plate of the reducer mounting base. The reducer mounting base is fixed to the roller mounting base, and the reducer base is firmly fixed and can withstand a lot of force. At the same time, it can withstand the downward pressure and rotational torque from the reducer, thereby ensuring the stability of the reducer and motor and ensuring the smooth rotation of the roller.

[0018] The two roller mounting seats are integrated and their positions are fixed to each other. The mounting surfaces of the bearing seats can be machined to ensure the flatness of the bearing seat mounting surfaces and to ensure that the bearing seat mounting surfaces of the two roller mounting seats are consistent. This ensures that the mounting positions of the bearing seats on both sides are consistent, thereby avoiding the bending stress caused by the roller spindle due to the bearing seats not being mounted on the same plane, and reducing the risk of roller shaft breakage.

[0019] The roller mounting base is reinforced with adjusting bolts. After adjusting the roller mounting base to the appropriate position, tighten the adjusting nut and then lock the adjusting bolt. This ensures that the roller mounting base is fixed simultaneously by the adjusting nut and the adjusting bolt. This multi-point positioning provides greater stability and ensures that the roller remains fully constrained during operation, making the operation more reliable and preventing roller shaft breakage or other damage caused by roller mounting base shaking.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Please refer to Figures 1 to 7 A preferred embodiment of this utility model provides a conveyor belt drive device, including a drive frame 10, roller mounting seats 11, rollers 12, bearing seats 14, a reducer 15, and a motor 16. The roller mounting seats 11 are mounted on both sides of the front end of the drive frame 10, with the two roller mounting seats 11 facing each other. The bearing seats 14 have their own bearings, and bearing seats 14 are fixedly mounted on the two roller mounting seats 11 respectively. The two ends of the main shaft 13 of the roller 12 are rotatably mounted on the roller mounting seats 11 through the bearing seats 14, thereby achieving smooth rolling of the roller 12. The reducer 15 and motor 16 are located on both sides of the front end of the drive frame 10. Each side is equipped with a reducer 15 and a motor 16. The two ends of the main shaft 13 of the roller 12 are connected to the motor 16 through the reducer 15. The motor 16 is a three-phase AC motor. The output of the motors 16 on both sides is reduced to the speed required for the operation of the roller 12 through the reducer and output through the hollow shaft of the reducer 15. The hollow shaft of the reducer 15 transmits power to the main shaft 13 of the roller 12 to drive the roller 12 to rotate. The rotation of the roller 12 can drive the conveyor belt wrapped around it to work normally. The motors 16 on both sides rotate together to ensure that the roller 12 rotates smoothly and steadily.

[0033] The main shaft 13 of the roller 12 is an integral through shaft, which facilitates processing and assembly, provides better stress distribution, ensures coaxiality at both ends, and prevents the main shaft 13 from breaking due to bending stress generated during rotation during operation.

[0034] Please continue to refer to Figures 1 to 5 A reducer base 17 is provided on the reducer 15, and the reducer base 17 is fixed to the reducer 15 by bolts. A connector 171 is provided on the reducer base 17, and the connector 171 is perpendicular to the reducer base 17. In this exemplary embodiment, the connector 171 is fixed to the reducer base 17 by welding, and the connector 171 has through holes on both sides of the connector 171. A reducer mounting base 18 is provided on the roller mounting seat 11, and the reducer mounting base 18 is fastened to the roller mounting seat 11 by bolts. Two opposing limiting plates 181 are provided on the reducer mounting base 18, and the two limiting plates 181 have limiting plate through holes facing each other. The connector 171 is located between two limiting plates 181. The through holes of the connector and the through holes of the limiting plates are aligned and a pin 19 is inserted therein. The pin 19 is fixed on the limiting plate 181. At this time, the two ends of the pin 19 are located in the limiting plate through holes of the two limiting plates 181, and the middle part passes through the connector through hole. In this way, the torque generated by the motor 16 driving the drum 12 to rotate through the reducer 15 on the reducer base 17 and the pin 19 connected thereto can be applied to both ends of the pin 19. Since both ends of the pin 19 are supported by the two limiting plates 181 of the reducer mounting seat 18, and the reducer mounting seat 18 is fixed to the drum mounting seat 11, the pin 19 is not easy to twist, break, or disconnect under the support and protection of the two limiting plates 181 of the reducer mounting seat 18. The reducer mounting seat 18 is fixed to the drum mounting seat 11, and the reducer base 17 is firmly fixed and can withstand a lot of force. At the same time, it can withstand the downward pressure and rotational torque from the reducer 15, thereby ensuring the stability of the reducer 15 and the motor 16 and ensuring the smooth rotation of the drum 12.

[0035] In a preferred embodiment, a bushing is fixedly installed in the through hole of the connector 171 by a buffer adhesive. The bushing is fitted onto the pin 19, allowing the connector 171 to rotate relative to the pin 19. That is, when the reducer base 17 is only connected to the pin 19, it can rotate relative to the pin 19. Of course, in actual use, the reducer base 17 is fixed on the reducer 15, and the reducer 15 interacts with the main shaft 13 of the roller 12. Therefore, the positions of the reducer base 17, the reducer 15, and the motor 16 are relatively fixed.

[0036] The reducer mounting base 18 also includes a reducer mounting base base plate 182 and an I-shaped mounting component 183. The reducer mounting base base plate 182 is fastened to the roller mounting base 11 with bolts to ensure stable installation. The I-shaped mounting component 183 is fixedly mounted on the reducer mounting base base plate 182 by welding. The I-shaped mounting component 183 includes vertical plates at both ends and a horizontal plate between the vertical plates. Both the vertical and horizontal plates are fixedly connected to the reducer mounting base base plate 182. Two limiting plates 181 are fixedly mounted on the middle horizontal plate of the I-shaped mounting component 183, and their ends are fixed to the two end vertical plates of the I-shaped mounting component 183 by welding. The reducer mounting base base plate 182 and the I-shaped mounting component 183 ensure a stable and reliable connection between the reducer mounting base 18 and the roller mounting base 11, as well as the stability and reliability of the two limiting plates 181.

[0037] A limiting block 191 is fixedly provided at one end of the pin 19. The fixing method is welding connection. The limiting block 191 is fastened to the limiting plate 181 on the same side by bolts. At this time, the pin 19 is fixed to the limiting plate 181 on the same side by bolts. That is, the pin 19 will not be axially displaced and will not be separated from the limiting plate 181, thus ensuring the reliability of the connection.

[0038] like Figures 1 to 3 as well as Figure 6 and Figure 7 As shown, in a preferred embodiment, a roller mounting bracket connector 111 is fixedly connected between the two roller mounting brackets 11 to make the two roller mounting brackets 11 an integral unit, that is, the positions of the two roller mounting brackets 11 are fixed to each other. This integral unit design, which fixes the positions of the two roller mounting brackets 11, allows for machining of the mounting surfaces of the bearing seats 14, ensuring the flatness of the bearing seat mounting surfaces and ensuring that the bearing seat mounting surfaces of the two roller mounting brackets 11 are consistent. This ensures that the mounting positions of the bearing seats 14 on both sides are consistent, thereby avoiding bending stress on the main shaft 13 of the roller 12 caused by the bearing seats 14 not being mounted on the same plane, and reducing the risk of roller 12 shaft breakage.

[0039] The drive frame 10 has sleeves 112 extending forward and backward on both sides, and a fixing plate 113 located behind the sleeves 112. The fixing plate 113 has a fixing plate through hole 114. The roller mounting base 11 is provided with a sliding member 115 that matches the sleeve 112. The end of the sliding member 115 is fixedly provided with a screw 116. The sliding member 115 is sleeved in the sleeve 112. The screw 116 passes through the fixing plate through hole 114, and the screw 116 is tightened with adjusting nuts 117 on both sides of the fixing plate 113. The sliding member 115 is sleeved in the sleeve 112 to achieve circumferential limitation. The adjusting nuts 117 are tightened on both sides of the fixing plate 113. At this time, the screw 116 is limited by the adjusting nuts 117 and cannot move axially. At this time, the roller mounting base 11 is limited and cannot move, so the roller mounting base 11 can be installed on the drive frame 10.

[0040] Preferably, locking screw holes 118 are provided on both sides of the drive frame 10, and elongated holes 119 extending forward and backward are provided on the roller mounting base 11. When the screw 116 of the roller mounting base 11 is fixed to the fixing plate 113 of the drive frame 10 by adjusting nut 117, the elongated holes 119 are aligned with the locking screw holes 118, and adjusting bolts 122 are screwed into the locking screw holes 118 to lock the roller mounting base 11 onto the drive frame 10. That is, by adjusting bolts 122 being screwed into the locking screw holes 118 to fasten the roller mounting base 11, the cooperation between the roller mounting base 11 and the drive frame 10 is further realized by the bolt locking method. The roller mounting base 11 is secured with adjusting bolts 122. After the roller mounting base 11 is adjusted to the appropriate position, tighten the adjusting nut 117 and then tighten the adjusting bolts 122. This makes the roller mounting base 11 fixed to the adjusting bolts 122 at the same time through the adjusting nut 117. The multi-point positioning is more secure, ensuring that the roller 12 is always fully constrained in the working state, making the operation more reliable and avoiding the roller 12 shaft breakage or other damage caused by the shaking of the roller mounting base 11.

[0041] Furthermore, a first transverse plate 120 is fixedly mounted on both sides of the drive frame 10 by welding, and a locking screw hole 118 is formed on the first transverse plate 120; a second transverse plate 121 is fixedly mounted on the roller mounting base 11 by welding, and an elongated hole 119 is formed on the second transverse plate 121. The first transverse plate 120 and the second transverse plate 121 are stacked vertically and fit together. The stacked first transverse plate 120 and the second transverse plate 121 can limit each other. At this time, by screwing the adjusting bolt 122 through the elongated hole 119 into the locking screw hole 118, a stable and reliable connection can be achieved between the first transverse plate 120 and the second transverse plate 121, that is, the roller mounting base 11 is stably and reliably mounted on the drive frame 10. There are multiple locking screw holes 118. For example, in this exemplary embodiment, each roller mounting base 11 has two locking screw holes 118. The number of adjusting bolts 122 and elongated holes 119 is consistent with the number of locking screw holes 118 and corresponds one-to-one with the locking screw holes 118. Through multi-point locking, a more reliable connection can be achieved.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
