Description

Technical Field

[0001] This utility model relates to the field of conveyor chain anti-deviation technology, and in particular to a coating conveyor chain anti-deviation device. Background Technology

[0002] In modern coating production lines, workpieces are usually transported on a pre-set track by a suspended conveyor chain system. Common conveyor chains are divided into single-chain and double-chain structures. In a single-chain structure, the chain may deviate due to various reasons, such as uneven tension after chain wear, frame deformation, the axis not being perpendicular to the chain centerline, or uneven support installation, etc.

[0003] In traditional conveyor chain anti-deviation devices, the chain is usually guided and corrected by external guide rails. However, most conveyor chain anti-deviation devices have guide rails of fixed size, which cannot be adjusted individually on the deviated side. This can easily lead to excessive friction between the chain and the guide rail, aggravating component wear and potentially causing chain jamming or even derailment. This seriously affects the continuous and stable operation of the coating production line. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the offset side independently, and to propose a coating conveyor chain anti-offset device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A coating conveyor chain anti-deviation device includes a mounting bracket for mounting a self-locking cylinder. One end of the piston rod of the self-locking cylinder passes through the mounting bracket. A slide is fixedly connected to one end of the self-locking cylinder. A guide wheel is fixedly connected to one side of the slide. A second sprocket is rotatably connected between the inner walls of the two sides of the guide wheel via bearings. A guide rail is fixedly connected between the inner walls of the two sides of the mounting bracket, and the slide slides along the guide rail. A corrugated cover is fixedly connected between one side of the slide and one side of an adjacent mounting bracket, and the piston rod of the self-locking cylinder is located inside the corrugated cover.

[0006] As a further embodiment of this utility model, both sides of the fixing frame are fixed with heat insulation covers by threads, and the self-locking cylinder is located inside the heat insulation cover.

[0007] As a further embodiment of this utility model, two rotating shafts are rotatably connected between the inner walls of the two sides of the fixing frame. A first sprocket is keyed to the outer side of each rotating shaft. The same chain is provided on the outer side of each first sprocket. Multiple support plates are provided on the top of the chain, and a second sprocket meshes with the chain.

[0008] As a further embodiment of this utility model, a motor is fixedly connected to one side of the fixing frame, and one end of the motor output shaft is fixed to one of the rotating shafts through a coupling.

[0009] As a further improvement of this utility model, the fixing frame has viewing windows on both sides.

[0010] As a further improvement of this utility model, wear-resistant bushings are provided at the connection between the self-locking cylinder piston rod and the fixed frame.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model is equipped with a self-locking cylinder and a guide wheel structure. The self-locking cylinder drives the slide to independently adjust the position of the guide wheel, which can accurately correct the offset of the two sides of the chain and avoid the wear problem caused by the inability to adjust the traditional fixed guide rail.

[0012] 2. This utility model is equipped with a heat insulation cover, which can isolate the high temperature in the coating environment from the effect of the self-locking cylinder, and prevent the cylinder from experiencing performance degradation or damage due to excessive temperature.

[0013] 3. The corrugated cover provided by this utility model can protect the piston rod of the self-locking cylinder, preventing external dust, paint and other impurities from entering the connection between the piston rod and the fixed frame, ensuring smooth sliding of the piston rod and extending the service life of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-4 A coating conveyor chain anti-deviation device includes a fixed frame 1, two rotating shafts 15 are rotatably connected between the inner walls of the two sides of the fixed frame 1, a first sprocket 12 is keyed to the outer side of the rotating shaft 15, the same chain 9 is provided on the outer side of the first sprocket 12, and multiple support plates 2 are provided on the top of the chain 9. A motor 5 is fixed to one side of the mounting bracket 1 by bolts, and one end of the output shaft of the motor 5 is fixed to one of the rotating shafts 15 by a coupling; A self-locking cylinder 6 is fixed to one side of the fixed frame 1 by bolts, and one end of the piston rod of the self-locking cylinder 6 passes through the fixed frame 1. The self-locking cylinder 6 is connected to an external air source. One end of the piston rod of the self-locking cylinder 6 is fixed to a slide 14 by bolts. A guide wheel 8 is rotatably connected to one side of the slide 14. A second sprocket 17 is rotatably connected between the inner walls of the two sides of the guide wheel 8 through a bearing, and the second sprocket 17 meshes with the chain 9. The inner walls of the two sides of the fixed frame 1 are fixed with guide rails 16 by bolts, and the slide 14 slides along the guide rails 16. When in use, the self-locking cylinder 6 is activated, and its piston rod pushes the slide 14 to slide along the guide rail 16, which drives the guide wheel 8 and the second sprocket 17 to pull the chain 9. Since the second sprocket 17 is engaged with the chain 9, the lateral position of the chain 9 can be limited to prevent the chain 9 from deviating to the left or right during operation. Meanwhile, the guide wheel 8 is coated with a smooth, wear-resistant coating. When the guide wheel 8 contacts the outer side of the chain 9, it can play an auxiliary guiding role when the chain 9 moves, further improving the stability of the chain 9's operation and avoiding the wear problem caused by the inability to adjust the traditional fixed track individually.

[0017] In this utility model, heat insulation covers 3 are fixed to both sides of the fixing frame 1 by threads, and the self-locking cylinder 6 is located inside the heat insulation cover 3. The heat insulation cover 3 isolates the self-locking cylinder 6 from the external high-temperature environment to prevent the cylinder from affecting normal operation due to overheating. One side of the slide 14 and the other side of the adjacent fixed frame 1 are both fixed with a corrugated cover 7 by bolts, and the piston rod of the self-locking cylinder 6 is located inside the corrugated cover 7. The corrugated cover 7 wraps and protects the piston rod, preventing dust, paint and other impurities from entering the moving area of ​​the piston rod and ensuring its smooth sliding.

[0018] In particular, both sides of the fixed frame 1 are provided with viewing windows 4, through which the offset can be observed. Wear-resistant bushings 10 are provided at the connection between the piston rod of the self-locking cylinder 6 and the fixed frame 1. The wear-resistant bushings 10 reduce the frictional loss between the piston rod and the fixed frame 1.

[0019] Working principle: Initially, the second sprocket 17 is in the middle position and meshes with the chain 9, while the first sprocket 12 and the second sprocket 17 are on the same straight line; When in use, after the motor 5 is started, it drives the shaft 15 connected to it to rotate through the output shaft, which in turn causes the first sprocket 12 on the shaft 15 to rotate synchronously. Under the transmission action of the chain 9, the other first sprocket 12 and the shaft 15 rotate accordingly, realizing the cyclic operation of the chain 9. The support plate 2 moves with the chain 9 to transport the workpiece. When chain 9 deviates during operation, the deviation can be observed through the viewing window 4 or through the support plate 2 on the surface. Then, the self-locking cylinder 6 is controlled to work, and its piston rod pushes the slide 14 to slide along the guide rail 16, which drives the guide wheel 8 and the second sprocket 17 to pull the chain 9 to move and apply an appropriate lateral force to it. Since the second sprocket 17 is engaged with the chain 9, the lateral position of the chain 9 can be limited to prevent the chain 9 from deviating to the left or right during operation.

[0020] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
