Abstract

The application relates to the field of material conveying, and discloses a one-way rotation adjusting device and a conveying equipment. The one-way rotation adjusting device comprises a rotating shaft, a gear, a linear driving assembly and an adjusting block. The gear is arranged on the rotating shaft, the gear has a plurality of gear teeth, a gear gap is formed between two adjacent gear teeth, the linear driving assembly is located on one side of the rotating shaft, the adjusting block is rotatably arranged on the driving end of the linear driving assembly, and the adjusting block is partially located in the gear gap. When the rotating shaft is reversely rotated by the gravity of the material, the adjusting block abuts against the gear teeth to prevent the gear from being reversely rotated, so that the material sliding on the belt and causing a blockage accident are avoided. When the equipment is maintained, the adjusting block is driven by the linear driving assembly to move out of the gear gap, so that the rotating shaft can be reversely rotated freely for equipment maintenance or accumulated material cleaning. The components do not need to be disassembled, the downtime is significantly shortened, and the labor intensity is reduced.

Description

Technical Field

[0001] This application relates to the field of material conveying, and more particularly to a unidirectional rotation adjustment device and conveying equipment. Background Technology

[0002] In tobacco processing production lines, inclined belt conveyors require intermittent operation due to process requirements. When the material flow exceeds the limit, the belt stops running. At this time, the weight of the belt and the weight of the material can easily drive the shaft to reverse, causing material to accumulate at the tail of the belt or even slide out of the channel, leading to blockages. The conventional solution to the reverse rotation problem is to add a mechanical anti-reverse device (such as a one-way locking mechanism) to the transmission system. However, such devices have significant drawbacks: during routine maintenance or troubleshooting, the anti-reverse component must be manually removed to reverse the belt's rotation in order to troubleshoot equipment blockages, clear accumulated material, or adjust the mechanism. This process is not only cumbersome but also requires machine shutdown for disassembly, significantly extending maintenance time, increasing labor intensity, and impacting production efficiency. Furthermore, repeated disassembly and reassembly can lead to component wear or installation errors, further reducing system reliability. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a unidirectional rotation adjustment device and conveying equipment.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides:

[0006] A unidirectional rotation adjustment device, comprising:

[0007] Shaft;

[0008] A gear, which is disposed on the rotating shaft, has multiple teeth, and a tooth gap is formed between two adjacent teeth;

[0009] A linear drive assembly, the linear drive assembly being located on one side of the rotating shaft;

[0010] An adjusting block is rotatably disposed at the drive end of the linear drive assembly, and the adjusting block is partially located within the tooth gap.

[0011] Furthermore, the linear drive assembly includes a linear drive member disposed on one side of the rotating shaft, the linear drive member having a drive shaft, and the adjusting block being rotatably disposed on the drive shaft.

[0012] Furthermore, the adjusting block includes an integrally formed connecting part and an adjusting part, the connecting part being rotatably mounted on the transmission shaft, and the end of the adjusting part facing away from the connecting part being disposed within the tooth gap.

[0013] Furthermore, one side of the adjustment section has an inclined guide surface.

[0014] Furthermore, the unidirectional rotation adjustment device also includes a limiting component, which includes a first switch and a second switch, the first switch and the second switch being located on both sides of the adjustment block shown.

[0015] Furthermore, the unidirectional rotation adjustment device also includes a controller, and an encoder is provided at the end of the rotating shaft, the encoder being electrically connected to the controller.

[0016] Furthermore, the unidirectional rotation adjustment device also includes an alarm device, which is electrically connected to the controller.

[0017] Furthermore, the alarm device is either a light or a sound.

[0018] This application also provides a conveying device, which includes:

[0020] A rotary drive component having a drive shaft that is connected to the rotating shaft in a transmission manner.

[0021] Furthermore, the drive shaft and the rotating shaft are connected by a coupling.

[0022] This application uses the material gravity to drive the shaft to reverse, and the adjusting block abuts against the teeth to prevent the gear from reversing, thereby avoiding material slipping on the belt and causing blockage accidents. During maintenance, the adjusting block is driven out of the tooth gap by the linear drive component, so that the shaft can be freely reversed for equipment maintenance or material cleaning, without disassembling parts, significantly shortening downtime and reducing labor intensity.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0034] This application provides a unidirectional rotation adjustment device, which includes a rotating shaft 100, a gear 200, a linear drive assembly 300, and an adjustment block 400. The gear 200 is disposed on the rotating shaft 100 and has a plurality of teeth 210, with a tooth gap 211 formed between two adjacent teeth 210. The linear drive assembly 300 is located on one side of the rotating shaft 100, and the adjustment block 400 is rotatably disposed on the drive end of the linear drive assembly 300, with part of the adjustment block 400 located within the tooth gap 211.

[0035] Please see Figure 1 As shown, the core operating logic of this unidirectional rotation adjustment device is based on a dynamic engagement mechanism of gear and adjustment block. Initially, the adjustment part 420 of the adjustment block 400 is partially embedded in the backlash 211 of the gear 200. Since the gear 200 is rigidly fixed to the rotating shaft 100 via a keyway or interference fit, the forward rotation (driving direction) of the rotating shaft 100 will synchronously drive the gear 200 to rotate. During this process, the sidewalls of the gear teeth 210 and the contact surface of the adjustment block 400 slide relative to each other: when the teeth 210 push the adjustment block 400, the adjustment block 400 can adaptively rotate a small angle around the transmission shaft 320 of the linear drive assembly 300, causing its adjustment part 420 to slide into the adjacent backlash 211. This process is adaptive, ensuring that the adjustment block 400 remains engaged with the backlash 211 during continuous forward operation of the device, and does not obstruct normal rotation.

[0036] When the conveyor belt stops due to material overload or sudden stop, the enormous gravity of the accumulated material generates a reverse driving torque, attempting to drag the shaft 100 to rotate in the opposite direction (i.e., reverse the trend). At this time, the reverse torque is transmitted to the gear 200, and the reverse thrust of the teeth 210 forces the adjusting part 420 of the adjusting block 400 to rigidly abut against the root of the teeth. Since the adjusting block 400 is fixed to the linear drive assembly 300 via the drive shaft 320 (at this time the assembly is in the locked position), this abutment force generates a self-locking effect on the adjusting block 400—the wedge-shaped structure of the adjusting part 420 (optionally with a slanted guide surface design) converts the reverse force into a radial biting force on the teeth 210, thereby completely locking the reverse movement of the gear 200 through static friction and mechanical interference. This process is completed within milliseconds, effectively preventing the shaft 100 and belt from reversing, and avoiding blockage of the conveyor channel or equipment damage caused by material accumulation due to sliding down.

[0037] When the equipment requires maintenance, repair, or cleaning of accumulated material, traditional mechanical anti-reverse devices require manual disassembly of locking components. This device, however, significantly improves efficiency through electronic control. Maintenance personnel activate the linear drive assembly 300 (e.g., a cylinder, electric actuator, or hydraulic cylinder), driving the transmission shaft 320 to move outwards along the axial direction of the gear 200 (i.e., parallel to the centerline of the rotating shaft 100). Since the adjusting block 400 is connected to the transmission shaft 320 via bearings or bushings, and its axial direction is fixed by a limiting ring, the linear displacement of the transmission shaft 320 synchronously drives the adjusting block 400 to move laterally. When the adjusting part 420 of the adjusting block 400 completely exits the backlash 211 area (the movement distance must be greater than the tooth height), the physical interference between the teeth 210 and the adjusting block 400 is completely eliminated. At this point, the belt can freely rotate in the opposite direction under the weight of the material or manual operation, and the rotating shaft 100 and gear 200 will subsequently reverse without obstruction, facilitating quick troubleshooting, clearing accumulated material, or adjusting the mechanism. After maintenance, the linear drive component 300 reverses its movement, pushing the adjustment block 400 back to its initial embedded position, and the device automatically restores its one-way locking function.

[0038] In some embodiments, the linear drive assembly 300 includes a linear drive member 310 disposed on one side of the rotating shaft 100, the linear drive member 310 having a drive shaft 320, and the adjusting block 400 being rotatably disposed on the drive shaft 320.

[0039] like Figure 1As shown, the drive shaft 320 is rotatably connected to the adjusting block 400. It can be understood that the drive shaft 320 is a rod, and the adjusting block 400 rotates around the drive shaft 320 as the rotation center. Since the linear drive 310 needs to drive the drive shaft 320 to move axially and thus drive the adjusting block 400 to move away from the backlash 211, the axial movement of the adjusting block 400 should be restricted at the connection between the drive shaft 320 and the adjusting block 400. That is, the adjusting block 400 cannot move axially relative to the drive shaft 320, so that the adjusting block 400 can be moved by the linear drive 310 through the drive shaft 320.

[0040] In some embodiments, the adjusting block 400 includes an integrally formed connecting portion 410 and an adjusting portion 420. The connecting portion 410 is rotatably disposed on the transmission shaft 320, and the end of the adjusting portion 420 facing away from the connecting portion 410 is disposed in the tooth gap 211.

[0041] The adjusting block 400 is located on one side of the rotating shaft 100. The connecting part 410 is rotatably connected to the transmission shaft 320. Specifically, the connecting part 410 can be installed with the transmission shaft 320 using a bearing, so that the connecting part 410 can rotate relative to the transmission shaft 320. The adjusting part 420 and the connecting part 410 are connected by integral molding. The adjusting part 420 is inclined relative to the connecting part 410, so that the end of the adjusting part 420 away from the connecting part 410 extends into the tooth gap 211 and abuts against the tooth 210. It can be understood that the angle between the adjusting part 420 and the connecting part 410 can be designed according to the working conditions, and the specific angle is not limited here.

[0042] In some embodiments, the adjustment part 420 has an inclined guide surface on one side.

[0043] In this embodiment, in order to enable the adjustment part 420 to automatically return to the state of being located in the tooth gap 211, a corresponding inclined guide surface can be provided on the side of the tooth gap 211. The inclined guide surface guides the adjustment part 420 to extend into the tooth gap 211, thereby satisfying the locking of automatic unidirectional rotation.

[0044] In practice, after the equipment has been repaired, the end of the toothed tooth 211 can be manually grasped and fed into the toothed tooth 211 to achieve unidirectional rotation locking.

[0045] In some embodiments, the unidirectional rotation adjustment device further includes a limiting component, which includes a first switch and a second switch, the first switch and the second switch being located on both sides of the adjustment block 400 shown.

[0046] like Figure 1As shown, in order to prevent the linear drive 310 from driving the adjustment part 420 to move too little or too much axial distance and thus failing to move out or into the backlash 211, two switches can be provided on both sides of the adjustment part 420. The two switches are used to determine whether the adjustment part 420 has reached the preset position, and the two switches are connected to the controller.

[0047] For example, both the first switch and the second switch can be limit switches or photoelectric switches, etc. When the adjustment unit 420 triggers the first switch or the second switch, the first switch or the second switch transmits a signal to the controller. The controller determines whether the adjustment unit 420 has reached the preset position. When the preset position is reached, the controller controls the linear drive 310 to stop moving the adjustment unit 420 through the transmission shaft 320.

[0048] In some embodiments, the unidirectional rotation adjustment device further includes a controller, and an encoder 500 is provided at the end of the rotating shaft 100, the encoder 500 being electrically connected to the controller.

[0049] Please continue reading. Figure 1 and Figure 2 As shown, in order to detect the rotation direction of the rotating shaft 100 in real time, the encoder 500 at the end of the rotating shaft 100 is used to detect the angle and direction of rotation, thereby determining whether the adjusting part 420 extends into the tooth gap 211. It can be understood that if the adjusting part 420 does not extend into the tooth gap 211, the material on the belt will drive the belt to rotate in the opposite direction under the action of gravity, thereby driving the rotating shaft 100 to rotate in the opposite direction, thus realizing the detection of the rotation direction of the rotating shaft 100. The encoder 500 detects the signal and transmits it to the controller. The controller analyzes and judges the signal from the encoder 500 to determine whether the rotating shaft 100 is in a reverse rotation state.

[0050] In some embodiments, the unidirectional rotation adjustment device further includes an alarm device electrically connected to the controller; the alarm device is one of light or sound.

[0051] In this embodiment, if the controller analyzes the signal from the encoder 500 and determines that the shaft 100 is rotating in the reverse direction, it indicates that the adjustment part 420 has not extended into the tooth gap 211. At this time, the controller can send an alarm signal to the alarm device, which will then issue an alarm to prompt the staff to perform maintenance and repair work. The alarm can be sound or light. That is, a red light can be used as an alarm, or a sound can be emitted through a speaker. In practice, a combination of sound and light can also be used to issue an alarm. The specific type is not limited here.

[0052] This embodiment also provides a conveying device, which includes the unidirectional rotation adjustment device and the rotary drive component as described above, wherein the rotary drive component has a drive shaft and the drive shaft is connected to the rotating shaft 100 in a transmission manner.

[0053] In this embodiment, the rotary drive is a motor, which drives the rotating shaft 100 to rotate, thereby driving the belt located on the circumference of the rotating shaft 100 to rotate, thus realizing the conveying of materials.

[0054] In some embodiments, the drive shaft and the rotating shaft 100 are connected by a coupling, which transmits power from the motor to the rotating shaft 100, thus completing the power transmission.

[0055] It is understood that the conveying equipment includes the aforementioned unidirectional rotation device, meaning that the conveying equipment has the technical effect of a unidirectional rotation device. The specific technical effect can be found in the above description and will not be elaborated here.
