Description

Technical Field

[0001] The utility model relates to a rotary anti-jumping tooth device and a conveyor, belonging to the technical field of conveying devices. Background Art

[0002] As an important conveying equipment, conveyor has a wide range of applications. It is not only used in traditional industries such as ports, grain and oil, chemical industry, metallurgy, etc., but also plays an irreplaceable role in modern industries such as light industry and power plants.

[0003] However, under long-term, high-load working conditions, the chain is affected by friction, wear and other factors, which gradually reduce the tightness of the chain. Therefore, after a long period of operation, the chain of the conveyor may become loose. Once the chain becomes loose, if measures are not taken in time to tighten it, it is very likely to jump teeth. Jumping teeth will not only cause the chip conveyor to shake and make noise, seriously affecting the normal operation of the equipment, but also have a huge impact on key components such as bearings and sprockets. This impact will not only cause damage to the bearings and sprockets, but may also cause overall equipment failure, and even have a serious impact on the stable operation of the production line. Utility Model Content

[0004] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0005] The technical solution provided by the utility model is as follows: a rotary anti-jumping tooth device, comprising a U-shaped guide frame and a support plate, wherein the support plate is arranged on the closed side of the U-shaped guide frame, and the support plate is used to be connected to the chassis.

[0006] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: when tooth jumping occurs, the U-shaped guide frame of the device effectively blocks the rotating component in a semi-enclosed manner, limiting the movement trajectory of the rotating component, thereby preventing the occurrence of tooth jumping and ensuring the smooth operation of the rotating component.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the support plate is provided with an elongated hole, and the U-shaped guide frame is connected to the support plate by fasteners passing through the elongated hole.

[0009] The beneficial effect of adopting the above further scheme is that the design of the long hole allows the position of the U-shaped guide frame on the support plate to be adjusted. According to the actual operation of the chain, the position of the U-shaped guide frame is adjusted along the long hole to ensure that the chain runs smoothly between the sprocket and the U-shaped guide frame.

[0010] Furthermore, it also includes a gasket, and a gasket is provided between the U-shaped guide frame and the support plate.

[0011] The beneficial effect of adopting the above further scheme is that the design of the gasket reduces vibration and noise, improves the service life and operating efficiency of the conveyor, and according to actual needs, the position of the U-shaped guide frame can be adjusted by adjusting the thickness of the gasket to adapt to chains of different specifications and types.

[0012] Furthermore, the support plate is provided with a plurality of mounting holes for connecting with the chassis.

[0013] The beneficial effect of adopting the above further solution is that the connection between the support plate and the chassis is more stable and reliable through the multiple mounting holes, ensuring that the rotary anti-jump tooth device is not easy to loosen or move during operation.

[0014] The utility model also discloses a conveyor, including a chassis, a motor, a sprocket and a chain, and also includes the rotating anti-tooth jump device as described above, the sprocket is rotatably installed in the chassis, the chain is located in the chassis, the chain is wrapped around the sprocket, the motor is transmission-connected to the sprocket, the support plate of the rotating anti-tooth jump device is fixed on the inner wall of the chassis, and the U-shaped guide frame of the rotating anti-tooth jump device is semi-enclosed on the upper and lower sides of the chain.

[0015] Compared with the prior art, the technical solution provided by the utility model has the following beneficial effects: when the chain is too loose, the U-shaped guide frame of the rotating anti-tooth jump device is fine-tuned toward the sprocket direction. When the tooth jump occurs, the U-shaped guide frame of the device effectively blocks the chain in a semi-enclosed manner to prevent it from jumping, thereby ensuring the smooth operation of the chain. This design not only eliminates the jitter and noise of the chip conveyor caused by tooth jumping, but also protects the bearings and sprockets from the impact damage caused by tooth jumping, thereby significantly extending their service life. The stable operation of the bearings and sprockets further ensures the working stability of the scraper, and finally achieves the smooth operation of the entire equipment, effectively extending the service life of the motor.

[0016] Furthermore, the chain includes a chain body and a plurality of scrapers, and the plurality of scrapers are arranged on the chain body at intervals.

[0017] The beneficial effect of adopting the above further scheme is that the scraper design makes the chain not only used for transmission, but also has the function of scraping and transporting materials. The scraper can effectively transport materials from one location to another, which is particularly useful in some industrial scenarios that require simultaneous material transportation and cleaning.

[0028] The support plate 120 is provided with an elongated hole 121 , and the U-shaped guide frame 110 is connected to the support plate 120 by fasteners such as bolts, threaded rods, pins, etc., passing through the elongated hole 121 .

[0029] A washer 130 is disposed between the U-shaped guide frame 110 and the support plate 120 .

[0030] A mounting hole 122 is formed at each of the four corners of the support plate 120 to connect the support plate 120 to the chassis 210 .

[0031] like Figure 4 - Figure 6 As shown, a conveyor includes a chassis 210, a motor 220, a sprocket 230 and a chain 240, and also includes the rotating anti-tooth jumping device 100, the sprocket 230 is rotatably installed in the chassis 210, the chain 240 is located in the chassis 210, the chain 240 is wrapped around the sprocket 230, the motor 220 is transmission-connected to the sprocket 230, the support plate 120 of the rotating anti-tooth jumping device 100 is fixed on the inner wall of the chassis 210, and the U-shaped guide frame 110 of the rotating anti-tooth jumping device 100 is semi-enclosed on the upper and lower sides of the chain 240.

[0032] The chain 240 includes a chain body 241 and a plurality of scrapers 242 . The plurality of scrapers 242 are arranged on the chain body 241 at intervals.

[0033] The installation method of the rotary anti-jump tooth device 100 of the utility model on the conveyor 200 is as follows:

[0034] Fix the support plate 120 in the chassis 210 through the mounting holes 122 thereon to ensure that the support plate 120 is stable and accurately positioned; place the U-shaped guide frame 110 on one side of the support plate 120, and adjust the position of the U-shaped guide frame 110 along the long hole 121 according to the actual operation of the chain 240 to ensure that the chain 240 runs smoothly between the sprocket 230 and the U-shaped guide frame 110; install the washer 130, and then fix the U-shaped guide frame 110 on the support plate 120 through the long hole 121 with fasteners.

[0035] When the chain 240 is too loose, the U-shaped guide frame 110 of the rotating anti-tooth jumping device 100 is finely adjusted toward the sprocket 230.
