Description

Technical Field

[0001] This utility model relates to the field of double-speed chain conveying technology, specifically a redirecting wheel mechanism applied to double-speed chain conveying. Background Technology

[0002] Patent CN208932361 U discloses a deflector mechanism for a double-speed chain conveyor, comprising a deflector body, a supporting shaft, a deflector fixing seat, and a shock absorber seat. The deflector body is mounted on the supporting shaft, with fixed bearings on both sides. A groove is located in the center of the deflector body, with sidewalls on both sides of the groove and oil injection holes at both ends of the sidewalls. Deflector fixing seats are located at both ends of the supporting shaft, and shock absorbers are located at the bottom of the deflector fixing seats. Mounting holes are located at the four corners of the shock absorbers, with fixing bolts inside the mounting holes. A hanging ring is located at the top of the deflector fixing seat. The groove and sidewalls on the deflector body are used to mount the double-speed conveyor chain, preventing displacement or detachment after prolonged use and increasing safety. Since there is some friction between the double-speed conveyor chain and the deflector body, the oil injection holes facilitate the injection of lubricating oil between them, improving their service life. This utility model is reasonably designed and suitable for widespread use.

[0003] The aforementioned prior art uses grooves and sides on the reversing wheel body to install the double-speed conveyor chain, ensuring stable operation and preventing displacement or detachment of the double-speed conveyor chain after long-term use, thus increasing the safety protection of the double-speed conveyor chain. There will be some friction between the double-speed conveyor chain and the reversing wheel body, and the oil injection hole facilitates the injection of grease or lubricating oil between them, improving their service life and reducing the failure rate. The setting of the reversing wheel fixing seat and shock absorber seat increases the stability of the reversing wheel body during operation. However, there is no corresponding structure for detecting the support shaft, and problems with the support shaft are not detected in time.

[0004] Therefore, a redirecting wheel mechanism for double-speed chain conveying is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a redirecting wheel mechanism for double-speed chain conveyors. This mechanism solves the problems of existing technologies that rely on grooves and sides on the redirecting wheel body for mounting the double-speed conveyor chain, ensuring stable operation, preventing displacement or detachment of the double-speed conveyor chain after prolonged use, and increasing the safety of the double-speed conveyor chain. While there is some friction between the double-speed conveyor chain and the redirecting wheel body, the oil injection hole facilitates the injection of grease or lubricating oil between them, improving their service life and reducing the failure rate. The inclusion of a redirecting wheel fixing seat and a shock-absorbing seat increases the stability of the redirecting wheel body during operation. However, the existing technology lacks a corresponding structure for detecting problems with the support shaft, thus failing to promptly identify any issues with the support shaft.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame, with a bearing embedded and fixedly connected to the inner sidewall of the frame; a limiting frame is bolted to the sidewall of the frame, a drive motor is bolted to the limiting frame, the output shaft of the drive motor is fixedly connected to a screw, the thread on the screw is threadedly connected to a drive plate, the drive plate is slidably connected to the limiting frame, a distance sensor is fixedly connected to the sidewall of the drive plate, and an electric push rod is fixedly connected to the other end of the drive plate, with the telescopic end of the electric push rod fixedly connected to a scraper.

[0007] Preferably, the inner ring of the bearing is fixedly connected to an output shaft, one end of which is fixedly connected to the output shaft of an external drive motor, and the drive motor is bolted to the side wall of the frame.

[0008] Preferably, the output shaft is fixedly connected to the center of the redirecting wheel, and a monitor is fixedly connected to the side wall of the frame.

[0009] Preferably, the scraper is arc-shaped; the limiting frame is parallel to the output shaft.

[0010] Preferably, the frame is provided with a controller, which is electrically connected to the monitor, drive motor, distance sensor and electric push rod.

[0011] Preferably, the bearing and the redirecting wheel are provided in two sets, respectively located at the left and right ends of the output shaft.

[0012] Preferably, the limiting frame has a concave structure, and the top and bottom of the drive plate are movably provided with ball bearings.

[0013] Compared with the prior art, this utility model provides a redirecting wheel mechanism for double-speed chain conveying, which has the following advantages:

[0014] 1. This redirecting wheel mechanism, applied to a double-speed chain conveyor, uses a distance sensor to measure the distance between itself and the output shaft, thereby detecting whether the output shaft has deformed. Once output shaft deformation is detected, timely repair or replacement measures can be taken to avoid failure of the entire redirecting wheel mechanism or even the double-speed chain conveyor system due to output shaft deformation, thus improving the maintainability and reliability of the equipment.

[0015] 2. This reversing wheel mechanism, applied to double-speed chain conveyors, has a monitor positioned above the reversing wheel for easy recording of its operation. Operators can observe the working status of the reversing wheel in real time through the monitor, promptly detect abnormalities such as chain loosening or reversing wheel jamming, and take corresponding measures to handle them, thereby improving the safety and stability of the entire double-speed chain conveyor system.

[0016] 3. This redirecting wheel mechanism, applied to double-speed chain conveyors, controls an electric push rod to drive a scraper to contact the side of the output shaft, and uses a drive motor to drive a screw to rotate, causing the drive plate to move and adjust the position of the scraper. While the output shaft rotates, the scraper can scrape off impurities from the surface of the output shaft. Attached Figure Description

[0022] 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.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 The present embodiment of a redirection wheel mechanism for a double-speed chain conveyor includes: a frame 1, a bearing 2 fixedly connected to the inner side wall of the frame 1, an output shaft 3 fixedly connected to the inner ring of the bearing 2, one end of the output shaft 3 being fixedly connected to the output shaft of an external drive motor, and the drive motor being bolted to the side wall of the frame 1.

[0025] The output shaft 3 is fixedly connected to the center of the idler wheel 4. The idler wheel 4 is directly connected to the drive motor through the output shaft 3. The motor drives the idler wheel to rotate, and the power is transmitted by the friction and meshing of the wheel surface groove and the chain roller. The monitor 5 is fixedly connected to the side wall of the frame 1. The circumferential surface of the idler wheel 4 is machined with annular grooves that match the pitch of the double-speed chain. The groove width is slightly larger than the diameter of the chain roller, usually 0.5 to 1 mm larger, to ensure that the chain roller can be accurately embedded in the groove and prevent deviation. The wheel body is made of 45# steel with quenching treatment or the surface is coated with polyurethane, which not only ensures wear resistance, but also increases friction through elastic material to avoid slippage. The monitor 5 is set above the idler wheel 4 to facilitate the recording of the operation of the idler wheel 4.

[0026] The scraper 12 is arc-shaped; the limiting frame 6 is parallel to the output shaft 3; a controller is provided on the frame 1, and the controller is electrically connected to the monitor 5, the drive motor 7, the distance sensor 10, and the electric push rod 11; the bearing 2 and the redirecting wheel 4 are provided in two sets, respectively located at the left and right ends of the output shaft 3; the limiting frame 6 has a concave structure, and the top and bottom of the drive plate 9 are provided with ball bearings.

[0027] At this time, a limiting frame 6 is bolted to the side wall of frame 1, a drive motor 7 is bolted to the inside of the limiting frame 6, the output shaft of the drive motor 7 is fixedly connected to the screw 8, the thread on the screw 8 is threaded to the drive plate 9, the drive plate 9 is slidably connected to the inside of the limiting frame 6, a distance sensor 10 is fixedly connected to the side wall of the drive plate 9, an electric push rod 11 is fixedly connected to the other end of the drive plate 9, and the telescopic end of the electric push rod 11 is fixedly connected to the scraper 12.

[0028] The working principle of the above embodiments is as follows:

[0029] In operation, the drive motor drives the output shaft 3 to rotate, which in turn drives the idler wheel 4 to rotate. The idler wheel 4 then drives the chain to move. As the chain moves forward, rolling friction occurs at the contact point between the roller and the workpiece, propelling the workpiece forward. Due to the rotation of the roller, the actual speed of the workpiece is twice the chain speed (typical value; the specific multiple depends on the roller diameter and chain pitch). During operation, the electric push rod 11 drives the scraper 12 to contact the side of the output shaft 3. The drive motor 7 drives the screw 8 to rotate, causing the screw 8 to move the drive plate 9. The drive plate 9 then drives the distance sensor 10. The electric push rod 11 and the scraper 12 move to adjust their positions. Simultaneously, the output shaft 3 rotates, allowing the scraper 12 to scrape away impurities from the surface of the output shaft 3, thus cleaning the surface of the output shaft 3. The surface is clean, and then the distance sensor 10 can be used to test the distance between it and the output shaft 3, and to test whether the output shaft 3 has deformed; according to the fault diagnosis results, corresponding fault troubleshooting measures are taken; if the bearing 2 is damaged, the output shaft 3 and related components should be disassembled first, then a new bearing 2 should be replaced, and reinstalled and adjusted; if the reversing wheel 4 is not installed firmly, the connecting bolts between the reversing wheel 4 and the output shaft 3 should be tightened to ensure a firm connection; if the output shaft 3 is deformed, the degree of deformation should be used to determine whether the output shaft 3 should be replaced; if the deformation is small, a correction process can be attempted; if the deformation is severe, a new output shaft 3 must be replaced; the operation between the reversing wheels 4 is captured by the monitor 5, which also monitors the reversing wheels 4.

[0030] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
