Abstract
Description
Technical Field
[0001] This utility model relates to the field of guide bar technology, specifically an adjustable guide bar structure. Background Technology
[0002] During the conveyor belt process, the guide bar is a key component that ensures the stable movement of the conveyor belt along the preset path. The rationality of its position adjustment directly affects the conveyor belt quality and subsequent processing accuracy. Currently, the industry mostly uses manual methods to adjust the position of the guide bar. When the width of the material belt changes, it is necessary to observe and manually adjust the guide bar. This is not only inefficient and difficult to adapt to the needs of continuous high-speed material belt conveying, but also prone to operational errors or delayed response, resulting in a mismatch between the guide bar and the material belt width, which in turn causes the material belt to deviate, affecting the continuity of production and product quality. Therefore, an adjustable guide bar structure is proposed. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides an adjustable guide bar structure to solve the problems mentioned in the background section.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an adjustable guide bar structure, comprising: The bottom frame has six rotating rollers equidistantly mounted inside it, and a laser profile sensor is installed at the feeding end inside the bottom frame between two rotating rollers. A servo motor is installed on the outside of the base frame on one side of the adjustment end. The output end of the servo motor is connected to a double-ended screw. Two sliding plates are threaded onto the double-ended screw. A guide strip is fixed to the top of the sliding plates. A linear displacement sensor is installed on the outside of the guide strip at the top of the bottom frame, and the linear displacement sensor is fixed to the bottom frame by a frame. It can capture the signal of the material strip width change in real time through the laser contour sensor, and then control the servo motor to drive the double-headed screw to move the slide plate and guide bar adaptively, so as to realize the automatic adjustment of the guide bar with the width of the material strip. At the same time, the linear displacement sensor can monitor the displacement of the guide bar in real time and feed back the signal, effectively ensuring the accuracy and timeliness of the guide bar adjustment, avoiding the lag and deviation problems of manual adjustment, and ensuring the stability of the material strip during the conveying process on the roller.
[0005] Preferably, the top of the bottom frame is provided with guide shells on both sides of the double-ended screw, and the guide shells are fixedly connected to the bottom frame. The guide shells are used to guide the rollers.
[0006] Preferably, L-shaped side frames are provided on both outer sides of the guide strip, and the L-shaped side frames are fixedly connected to the guide strip. The L-shaped side frames are used to install rollers.
[0007] Preferably, a roller is installed inside the L-shaped side frame, located inside the guide shell, and the roller is rotatably connected to the L-shaped side frame. The roller is used to guide the movement of the guide bar and improve stability.
[0008] Preferably, the inner side of the guide strip is provided with a wear-resistant coating, and the wear-resistant coating is connected to the guide strip. The wear-resistant coating improves the wear resistance of the guide strip, thereby increasing its service life.
[0009] Preferably, the laser contour sensor is fixedly connected to the base frame, and the servo motor is connected to the base frame via a frame.
[0010] Compared with the prior art, the present invention provides an adjustable guide bar structure, which has the following advantages: This invention uses a laser contour sensor to detect changes in the width of the conveyor belt in real time. Based on this signal, a servo motor is started and drives a double-headed screw to rotate, causing the sliding plate threaded to the double-headed screw and the guide strip fixed at the top to move synchronously. At the same time, a linear displacement sensor detects the displacement of the guide strip in real time and feeds it back to the controller, realizing the function of automatic adjustment of the guide strip according to the width of the conveyor belt. It has the advantages of no manual intervention and timely and accurate adjustment, solving the problems of low efficiency and easy deviation of conveyor belt due to adjustment lag or deviation when manually adjusting the guide strip.

[0013] 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.
[0014] This utility model provides a technical solution, an adjustable guide bar structure; please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include: The bottom frame 1 has six rotating rollers 2 equidistantly mounted inside the bottom frame 1. A laser profile sensor 3 is set at the feeding end inside the bottom frame 1 between two rotating rollers 2. A servo motor 4 is installed on the outside of the base frame 1 on one side of the adjustment end. The output end of the servo motor 4 is connected to a double-ended screw 5. Two slide plates 7 are threaded onto the double-ended screw 5. A guide strip 6 is fixed to the top of the slide plate 7. A linear displacement sensor 8 is installed on the outside of the guide strip 6 at the top of the bottom frame 1, and the linear displacement sensor 8 is fixed to the bottom frame 1 by the frame. The laser contour sensor 3 is externally connected to a controller, which is also connected to a servo motor 4 and a linear displacement sensor 8.
[0015] Please see Figure 1 , Figure 2 and Figure 3 The top of the bottom frame 1 is provided with guide shells 10 on both sides of the double-headed screw 5, and the guide shells 10 are fixedly connected to the bottom frame 1. The guide shells 10 are used to guide the rollers 12.
[0016] Please see Figure 3 L-shaped side frames 11 are provided on both sides of the outer side of the guide bar 6, and the L-shaped side frames 11 are fixedly connected to the guide bar 6. The L-shaped side frames 11 are used to install the rollers 12.
[0017] Please see Figure 3 Inside the L-shaped side frame 11, inside the guide shell 10, there is a roller 12, and the roller 12 is rotatably connected to the L-shaped side frame 11. The roller 12 is used to guide the movement of the guide bar 6 and improve stability.
[0018] Please see Figure 1 and Figure 2 The inner side of the guide strip 6 is provided with a wear-resistant coating 9, and the wear-resistant coating 9 is connected to the guide strip 6. The wear-resistant coating 9 improves the wear resistance of the guide strip 6, thereby increasing its service life.
[0019] Please see Figure 1 The laser contour sensor 3 is fixedly connected to the base frame 1, and the servo motor 4 is connected to the base frame 1 through the frame.
[0020] In this solution: when the material strip is conveyed on the roller 2, the laser contour sensor 3 detects the change in the width of the material strip and transmits the detected signal to the controller; the controller controls the servo motor 4 to start based on the signal, and the servo motor 4 then drives the double-headed screw 5 to rotate; since the slide plate 7 is threadedly connected to the double-headed screw 5, and the guide shell 10 on the guide bar 6 has a roller 12 rotatably installed inside, the roller 12 rolls with the bottom frame 1. This structure can effectively improve the stability of the guide bar 6 when it moves, and avoid the guide bar 6 from deviating or getting stuck. Therefore, the rotation of the double-headed screw 5 will drive the slide plate 7 to move along the length direction of the double-headed screw 5, thereby making it move with the roller 7. The guide bar 6, which is fixedly connected to the slide plate 7, moves synchronously. During the movement of the guide bar 6, the linear displacement sensor 8 detects the displacement of the guide bar 6 in real time and feeds the displacement signal back to the controller, thereby achieving precise control of the position of the guide bar 6. The component with a wear-resistant coating 9 above the roller 2 can reduce the wear caused by the material belt contacting the component and extend the service life of the component. Through the coordinated operation of the laser contour sensor 3, servo motor 4, double-headed screw 5, slide plate 7, linear displacement sensor 8, guide shell 10, roller 12 and other structures, the position of the guide bar 6 can be automatically adjusted according to the width of the material belt, thereby ensuring stable conveying of the material belt.
