Description

Technical Field

[0001] This application belongs to the field of conveyor technology, specifically a conveyor positioning and clamping mechanism to prevent deviation. Background Technology

[0002] Anti-deviation conveyors are a type of material handling equipment that can effectively constrain the lateral movement of materials or workpieces during continuous conveying, prevent deviation, and ensure that the conveyed object runs accurately and stably along a preset path. They are widely used in scenarios where subsequent processing and assembly require high conveying accuracy. Traditional anti-deviation conveyors mainly rely on passive constraint or correction methods. Among them, the self-aligning idler group structure is widely used. When the conveyor belt deviates, the self-aligning idler can automatically rotate at a certain angle, generating lateral friction to push the conveyor belt back to the center position. In addition, there are also V-shaped guide grooves or specially arranged rollers that form support and guidance from both sides of the bottom of the material to limit material deviation.

[0003] However, the existing self-aligning idler assembly achieves anti-deviation by automatically rotating the self-aligning idler at a certain angle when the conveyor belt deviates, and pushing the conveyor belt back to the center position through lateral friction. However, the self-aligning idler itself lacks a positioning and clamping mechanism, and can only passively reset after deviation. During the reset process, the idler is prone to shaking or shifting due to uneven force, resulting in insufficient reset accuracy of the conveyor belt. Moreover, the idler has no stable clamping constraint and cannot ensure that the conveyor belt is centered for a long time through its own posture locking. This passive and inaccurate anti-deviation method is difficult to stabilize the material conveying posture. Therefore, a conveyor positioning and clamping mechanism to prevent deviation is provided. Utility Model Content

[0004] The purpose of this application is to provide a conveyor positioning and clamping mechanism that prevents deviation in order to solve the problems mentioned above.

[0005] The technical solution adopted in this application is as follows: a conveyor positioning and clamping mechanism for preventing deviation, including a fixed base plate, a self-aligning roller group rotatably disposed on the top surface of the fixed base plate, a connecting rotating shaft fixed at the center of the bottom surface of the self-aligning roller group, the connecting rotating shaft passing through and rotatably connected to the fixed base plate, a driving assembly for driving the connecting rotating shaft to rotate on the bottom surface of the fixed base plate, and a positioning and clamping assembly for positioning and clamping the connecting rotating shaft on the top surface of the fixed base plate; The positioning and clamping assembly includes a circular connecting plate, triangular holes, a mounting housing, an electromagnet, and a triangular locking rod. The circular connecting plate is fixedly sleeved on the outer surface of the connecting rotating shaft near the top end, and its outer circumference has multiple triangular holes arranged in a circular array. The mounting housing is symmetrically fixed on the top surface of the fixed base plate, and an electromagnet is fixed on the bottom of the mounting housing. The telescopic end of the electromagnet extends upward into the interior of the mounting housing and is connected to the triangular locking rod. The triangular locking rod is movably inserted through the top surface of the mounting housing, and its top end can be selectively inserted into any one of the triangular holes.

[0006] In a preferred embodiment, the drive assembly includes a large gear, a drive motor, and a small gear. The large gear is fixed to the bottom end of the connecting rotating shaft, the drive motor is fixedly mounted on the bottom surface of the fixed base plate, and its output end is fixed with a small gear that meshes with the large gear.

[0007] In a preferred embodiment, a bearing seat is fixed to the center of the top surface of the fixed base plate, and the connecting rotating shaft passes through and is fixed inside the bearing seat.

[0008] In a preferred embodiment, two connecting rods are fixedly installed on the bottom surface of the self-aligning idler group, and an annular seat corresponding to and adapted to the connecting rods is provided on the top surface of the fixed base plate. The bottom end of the connecting rod extends into the annular seat, and an auxiliary moving wheel that rolls in contact with the inner wall of the annular seat is rotatably connected to the bottom of the annular seat.

[0010] In a preferred embodiment, the annular seat is fixed to the top surface of the base plate by means of hexagonal socket head cap screws.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are: 1. In this application, due to the adoption of the above-mentioned scheme, when the self-aligning idler group rotates to the target angle, the system de-energizes the electromagnet of the positioning clamping component. Its telescopic end moves upward under the action of the spring, pushing the triangular locking rod to move upward along the guide hole of the mounting housing. The top end is inserted into the triangular hole of the circular connecting plate. The triangular structure cooperates to restrict the circumferential rotation of the circular connecting plate, locking the angle between the connecting rotating shaft and the self-aligning idler group, preventing the self-aligning idler group from retreating due to the friction of the conveyor belt, and ensuring the stability of the conveyor belt. When adjustment is required, the electromagnet is energized, the armature is reset, and the triangular locking rod is disengaged from the triangular hole. This device corrects the conveyor belt offset by rotating the self-aligning idler group and ensures its stability by positioning and clamping it. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] refer to Figures 1-5 As shown, a conveyor positioning and clamping mechanism for preventing deviation includes a fixed base plate 1, with mounting holes 10 for installation and fixing at both ends of the fixed base plate 1. By setting the mounting holes 10, the entire mechanism can be easily bolted to the conveyor frame, adapting to the anti-deviation requirements of conveyors of different specifications.

[0016] refer to Figures 1-5As shown, a self-aligning idler group 2 is rotatably mounted on the top surface of the fixed base plate 1. A connecting rotating shaft 3 is fixed at the center of the bottom surface of the self-aligning idler group 2. The connecting rotating shaft 3 passes through and is rotatably connected to the fixed base plate 1. A bearing seat 6 is fixed in the middle of the top surface of the fixed base plate 1. The connecting rotating shaft 3 passes through and is fixed inside the bearing seat 6. Through the self-aligning idler group 2, when the externally installed photoelectric sensor detects that the conveyor belt is deviated, it can directly carry the conveyor belt to correct it. The connecting rotating shaft 3 achieves rotation around the center. With the precise guidance of the bearing seat 6, the radial runout when the connecting rotating shaft 3 rotates can be reduced, ensuring the stable rotation posture of the self-aligning idler group 2 and avoiding secondary deviation of the conveyor belt due to shaft shaking. At the same time, the bearing seat 6 can also distribute the force on the connecting rotating shaft 3.

[0017] refer to Figures 1-5 As shown, the bottom surface of the fixed base plate 1 is provided with a drive assembly 4 for driving the rotating shaft 3 to rotate. The drive assembly 4 includes a large gear 401, a drive motor 402, and a small gear 403. The large gear 401 is fixed to the bottom end of the rotating shaft 3, and the drive motor 402 is fixedly installed on the bottom surface of the fixed base plate 1. The output end of the drive motor 402 is fixed with a small gear 403 that meshes with the large gear 401. Through the speed reduction transmission structure of the drive motor 402 driving the small gear 403 and the large gear 401, the rotation speed of the self-aligning idler group 2 can be reduced, achieving fine-tuning control and avoiding excessive instantaneous deviation of the conveyor belt due to excessive rotation. At the same time, the stability of the gear meshing transmission is better than that of belt transmission, ensuring the accurate rotation angle of the self-aligning idler group 2.

[0018] refer to Figures 1-5 As shown, two connecting rods 7 are fixedly installed on the bottom surface of the self-aligning idler group 2. The top surface of the fixed base plate 1 is provided with an annular seat 8 that corresponds to and matches the connecting rods 7. The annular seat 8 is fixed to the top surface of the fixed base plate 1 by hexagonal bolts. The bottom end of the connecting rod 7 extends into the annular seat 8, and the bottom of the annular seat 8 is rotatably connected to an auxiliary moving wheel 9 that rolls in contact with the inner wall of the annular seat 8. The top surface of the fixed base plate 1 is provided with a positioning and clamping assembly 5 for positioning and clamping the connecting rotating shaft 3. By symmetrically distributing the two connecting rods 7, the annular seat 8 and the auxiliary moving wheel 9 form an annular guide structure, which can provide auxiliary support when the self-aligning idler group 2 rotates, and prevent the idler group from tilting due to unilateral force. The rolling contact between the auxiliary moving wheel 9 and the inner wall of the annular seat 8 can reduce the frictional resistance when the self-aligning idler group 2 rotates, ensuring smooth rotation. At the same time, the annular seat 8 is fixed by hexagonal bolts, which facilitates disassembly and maintenance in the future.

[0019] refer to Figures 1-5As shown, the positioning and clamping assembly 5 includes a circular connecting plate 501, a triangular hole 502, a mounting housing 503, an electromagnet 504, and a triangular locking rod 505. The circular connecting plate 501 is fixedly sleeved on the outer surface of the connecting rotating shaft 3 near its top end. Multiple triangular holes 502 are arranged in a circumferential array on its outer periphery. The mounting housing 503 is symmetrically fixed to the top surface of the fixed base plate 1. The electromagnet 504 is fixed to the bottom of the mounting housing 503. The telescopic end of the electromagnet 504 extends upward into the interior of the mounting housing 503 and is connected to the triangular locking rod 505. The triangular locking rod 505 movably passes through the top surface of the mounting housing 503, and its… The top can be selectively inserted into any of the triangular holes 502; the electromagnet 504 can drive the triangular locking rod 505 to move up and down. The cooperation structure between the triangular hole 502 and the triangular locking rod 505 can prevent circumferential slippage of the connecting rotating shaft 3 after locking. At the same time, the two symmetrically arranged positioning clamping components 5 can move synchronously to ensure that the circular connecting plate 501 is subjected to balanced force, which solves the problem of shaft deformation caused by traditional single-sided clamping. The model of the electromagnet 504 can be MFZ1-3.5, which can meet the insertion and removal requirements of the triangular locking rod 505, and its small size is suitable for the internal space of the mounting housing 503.

[0020] The implementation principle of the anti-deviation conveyor positioning and clamping mechanism embodiment of this application is as follows: First, the user fixes the entire mechanism to the designated position on the conveyor frame using bolts through the mounting holes 10 at both ends of the fixed base plate 1, ensuring that the top surface of the self-aligning idler roller group 2 is in contact with the bottom surface of the conveyor belt. During the active self-aligning process, when the conveyor belt deviates during conveyor operation (the deviation signal can be detected by the photoelectric sensor built into the conveyor), the system sends a start signal to the drive motor 402 of the drive assembly 4. The drive motor 402 drives the pinion 403 at the output end to rotate. The large gear 401 is driven to rotate by meshing transmission, which in turn causes the connecting rotating shaft 3, which is fixed to the large gear 401, to rotate synchronously. At this time, the self-aligning idler group 2 on the top surface can be driven to rotate around the center through the connecting rotating shaft 3. At the same time, the connecting support rod 7 on the bottom surface of the self-aligning idler group 2 rotates with the idler group, and the auxiliary moving wheel 9 rolls on the inner wall of the ring seat 8 to provide stable guidance for the idler group. When the self-aligning idler group 2 rotates to the preset angle, the drive motor 402 stops running. At this time, the inclined surface of the self-aligning idler group 2 generates lateral friction force, which gradually pushes the conveyor belt back to the center position, realizing active self-alignment. When the self-aligning idler roller assembly 2 rotates to the target angle, the system de-energizes the electromagnet 504 of the positioning clamping assembly 5. At this time, the telescopic end of the electromagnet 504 extends upward under the action of the spring, pushing the connected triangular locking rod 505 upward along the guide hole of the mounting housing 503 until the top of the triangular locking rod 505 is inserted into the corresponding triangular hole 502 on the outer periphery of the circular connecting disc 501. Since the triangular hole 502 matches the shape of the triangular locking rod 505, the circumferential rotation of the circular connecting disc 501 can be restricted, thereby... The angle between the locking rotating shaft 3 and the self-aligning idler group 2 is locked to prevent the self-aligning idler group 2 from retracting under the friction of the conveyor belt, ensuring that the conveyor belt remains stably in the center position. If the self-aligning angle needs to be adjusted later, simply energize the electromagnet 504, the armature resets and drives the triangular locking rod 505 to disengage from the triangular hole 502, and repeat step 2. This device can effectively perform anti-deviation correction operation on the conveyor belt and position and clamp the self-aligning idler group 2 to maintain stability by rotating the self-aligning idler group 2.
