Description

Technical Field

[0001] This utility model relates to the field of automated production technology, and in particular to a servo-driven conveyor roller structure. Background Technology

[0002] In the field of automated production, the accuracy and stability of material conveying directly affect production efficiency. Traditional conveyor rollers are mostly driven by ordinary motors, which have problems such as poor speed synchronization and large conveying deviations. With the development of servo motor technology, servo-driven conveyor rollers are gradually replacing traditional equipment and are widely used in high-precision production lines because they can precisely control the speed and adapt to the conveying needs of various materials. However, existing servo-driven conveyor rollers still do not fully meet the diverse needs of complex production scenarios. The existing servo-driven conveyor roller structure is based on support and transmission: it includes two parallel fixed long plates as a skeleton, with multiple evenly arranged rotating rollers connected internally to form a conveying surface; one of the fixed long plates has servo motors fixed on both sides, and the motors drive multiple sets of rotating rollers to rotate synchronously through belt transmission; a controller is set on the outside of the rear fixed long plate to adjust the motor parameters; the bottom fixed plate provides support for the overall structure and ensures the stability during operation. However, the existing equipment has two key shortcomings: First, it lacks a height adjustment structure, and the height of the conveying surface is fixed, which cannot adapt to the different height requirements of upstream equipment and downstream platforms. Additional shims are required, which is cumbersome to operate. Second, it lacks a material clamping mechanism. During the conveying process, thin or easily shifted materials are prone to positional shifts due to vibration or speed changes, which can lead to errors in subsequent process connections and affect production accuracy. Therefore, a servo-driven conveying roller structure is proposed to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a servo-driven conveyor roller structure, which aims to improve the problems of lack of clamping and adjustment when used at different heights in the prior art.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a servo-driven conveyor roller structure, comprising two fixed long plates, each of which is rotatably connected to multiple rotating rollers; two servo motors are fixedly connected to the left and right sides of one of the fixed long plates; a controller is fixedly connected to the outer side of the rear fixed long plate; a fixed plate is fixedly connected to the bottom of the two fixed long plates; a rotating shaft is rotatably connected to the top of the fixed plate; a second connecting rod is rotatably connected inside the rotating shaft; a first connecting rod is rotatably connected to both sides of the second connecting rod; a slider is rotatably connected to the end of each of the first connecting rods away from the rotating shaft; a plate is fixedly connected to the top of each of the two sliders; two cylinders are fixedly connected to the top of each of the two plates; an electric push rod is fixedly connected to the outer side of the rear slider; a slider is fixedly connected to the output end of the electric push rod; multiple rotating rollers penetrate the fixed long plates at the front; and belts are sleeved on the outer sides of the multiple rotating rollers at the front. As a further description of the above technical solution: The lifting mechanism includes a lifting plate, with two fixed plates fixedly connected to the top of the lifting plate and two fixed long plates fixedly connected to the bottom of the lifting plate. An X-shaped connecting rod is rotatably connected between the upper and lower fixed plates. A hydraulic rod is fixedly connected to the left side of the top of the lifting plate, and a slide rail is fixedly connected to the right side of the top of the lifting plate. A slide rail is fixedly connected to the right side of the bottom of the long plate, and a fixed block is slidably connected to the outside of the slide rail. As a further description of the above technical solution: The output ends of both servo motors are fixedly connected inside the two rotating rollers through a fixed long plate; As a further description of the above technical solution: The right end of the X-shaped connecting rod is rotatably connected to the outside of the fixed block; As a further description of the above technical solution: Both sliders are slidably connected to the outside of the fixed plate at their bottoms; As a further description of the above technical solution: The top of the rotating shaft is rotatably connected inside the electric push rod; As a further description of the above technical solution: One side of the hydraulic rod is fixedly connected to the inside of the bottom fixing block.

[0005] This utility model has the following beneficial effects: 1.

[0009] 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.

[0010] Reference Figures 1-4This utility model provides an embodiment of a servo-driven conveyor roller structure, comprising two fixed long plates 1, each with multiple rotating rollers 2 rotatably connected inside. Two servo motors 3 are fixedly connected to both sides of one of the fixed long plates 1, and a controller 4 is fixedly connected to the outer side of the rear fixed long plate 1. Fixed plates 5 are fixedly connected to the bottom of the two fixed long plates 1, and a rotating shaft 12 is rotatably connected to the top of the fixed plates 5. A second connecting rod 8 is rotatably connected inside the rotating shaft 12, and connecting rods 7 are rotatably connected to both sides of the second connecting rod 8. Slider 6 is rotatably connected to the ends of the two connecting rods 7 away from the rotating shaft 12, and plate 10 is fixedly connected to the top of each of the two sliders 6. Each part is fixedly connected to two cylinders 11. An electric push rod 9 is fixedly connected to the outside of the rear slider 6. The output end of the electric push rod 9 is fixedly connected to the slider 6. Multiple rotating rollers 2 pass through the fixed long plate 1 on the front side. A belt 20 is sleeved on the outside of the multiple rotating rollers 2 on the front side. After the conveying device is started, the required items above are conveyed to the far right and then the electric push rod 9 is started. The electric push rod 9 drives the two sliders 6 to slide on the fixed plate 5, which drives the rotating connecting rod 7 on the slider 6 to rotate. The rotation of the connecting rod 7 drives the second connecting rod 8 to rotate. The second connecting rod 8 rotates on the rotating shaft 12 to clamp the conveyed items. When the servo-driven conveying device is started, the operating parameters of the servo motor 3 are first set through the controller 4 on the outside of the rear fixed long plate 1. Then the device is started: the output end of the servo motor 3 drives the corresponding rotating roller 2 to rotate through the coupling. The multiple rotating rollers 2 on the front side achieve synchronous transmission with the belt 20 sleeved on the outside, forming a stable horizontal conveying power. The item to be transported is smoothly placed on the conveying surface composed of multiple rotating rollers 2. Under the friction of the rotating rollers 2, the item moves smoothly along the length of the fixed long plate 1 towards the far right of the device. Upon reaching the designated position, the controller 4 controls the servo motor 3 to stop operating, and the item precisely stops in the clamping operation area on the far right. Next, the controller 4 automatically starts the electric push rod 9. The output end of the electric push rod 9 generates axial thrust, driving the rear slider 6, which is fixedly connected to it, to slide inward along the groove on the top of the fixed plate 5. At the same time, the front slider 6 is driven to move inward synchronously through the connecting rod 7. Since both sliders 6 are rotatably connected to the connecting rod 7, they rotate synchronously towards the center of the device. The other end of the connecting rod 7 is rotatably connected to the connecting rod 8. The electric push rod 9 pulls the sliders 6, thereby pulling the two plates 10 associated with the connecting rod 8 towards the center of the device. As the two plates 10 move toward each other, the vertically fixed cylinder 11 at their top moves inward in sync. After the top of the cylinder 11 contacts the two sides of the item, the controller 4 stabilizes the clamping structure through the current feedback of the electric push rod 9, firmly fixing the item transported to the far right, which facilitates subsequent assembly, testing, etc., and improves operational stability and work efficiency.

[0011] Reference Figure 1 and Figure 5 The lifting mechanism includes a lifting plate 16. A fixed plate 18 is fixedly connected to the top of the lifting plate 16, and two fixed long plates 1 are fixedly connected to the bottom. An X-shaped connecting rod 13 is rotatably connected between the upper and lower fixed plates 18. A hydraulic rod 17 is fixedly connected to the left side of the top of the lifting plate 16, and a slide rail 15 is fixedly connected to the right side of the top of the lifting plate 16. A slide rail 15 is also fixedly connected to the right side of the bottom of the long plate 19. A fixed block 14 is slidably connected to the outside of the slide rail 15. When the device is needed, the lower hydraulic rod 17 is activated, which extends and retracts, pushing the fixed block 14 to slide on the slide rail 15. The sliding of the fixed block 14 causes the X-shaped connecting rod 13 to move, which in turn causes the lifting plate 16 to move. The lifting plate 16 then causes the slide plate to move up and down, thus solving the problem of adjustable height for various conveying needs.

[0012] Reference Figures 1-4 The output ends of the two servo motors 3 are fixedly connected to the inside of the two rotating rollers 2 through the fixed long plate 1, so that the belt 20 can provide power to the device.

[0013] Reference Figure 1 and Figure 5 The right end of the X-shaped connecting rod 13 is rotatably connected to the outside of the fixed block 14.

[0014] Reference Figures 1-4 Both sliders 6 are slidably connected to the outside of the fixed plate 5 at their bottom, which better drives the first connecting rod 7 and the second connecting rod 8 to rotate.

[0015] Reference Figures 1-4 The top of the rotating shaft 12 is rotatably connected inside the electric push rod 9 for better rotation.

[0016] Reference Figures 1-4 One side of the hydraulic rod 17 is fixedly connected to the inside of the bottom fixing block 14 for better height adjustment.

[0017] Working principle: When the device is in use, the hydraulic rod 17 is activated, which extends and retracts to push the fixed block 14 to slide on the slide rail 15. The sliding of the fixed block 14 causes the X-shaped connecting rod 13 to move. The movement of the X-shaped connecting rod 13 drives the lifting plate 16 to move. The lifting plate 16 drives the sliding plate to move up and down, thus solving the problem of height adjustment when facing various conveying requirements. Then, the conveying device is started to transport the required items to the far right. Subsequently, the electric push rod 9 is activated. The electric push rod 9 drives the two sliders 6 to slide on the fixed plate 5, which drives the connecting rod 7 rotatably connected to the sliders 6 to rotate. The rotation of the connecting rod 7 drives the connecting rod 8 to rotate. The connecting rod 8 rotates on the rotating shaft 12, which in turn drives the two plates 10 to move closer together, and drives the fixed cylinder 11 above to move closer together, thus clamping the conveyed items.

[0018] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
