Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figures 1-6 The image shows the liftable conveyor roller conveyor of this utility model, which includes a base 1, a drive mechanism 2 and a lifting assembly 3 on the base 1. The drive mechanism 2 drives the lifting assembly 3 to rise and fall. The top of the lifting assembly 3 is provided with a conveying assembly 4. The output end of the conveying assembly 4 is provided with an anti-fall mechanism 5 to prevent materials from falling off at the end.

[0020] like Figure 1 and Figure 2 As shown, the base 1 is a frame structure made of sturdy metal material, which has sufficient strength to support the weight of the entire device and the dynamic load during transportation.

[0021] like Figures 1-3As shown, the drive mechanism 2 includes a first drive motor 21, which is fixedly mounted on the base 1. A first driving wheel 22 is fixedly mounted on the output shaft of the first drive motor 21, and a first driven wheel 23 is rotatably mounted on the base 1. A first transmission belt 24 is fitted onto the first driving wheel 22 and the first driven wheel 23. The lifting assembly 3 includes a screw jack 31 and a lifting frame 32. The power input end of the screw jack 31 is fixedly connected to the first driven wheel 23 via a connecting shaft (not shown in the figure). The nut 312 of the screw jack 31 is fixedly connected to the lifting frame 32. The nut 312 is fitted onto the outside of the screw jack 311 and threadedly connected to the screw jack 311. The screw jack 31 can be any commercially available mature product, regardless of brand or model, and can be selected and configured according to the actual design. The bottom of the lifting frame 32 is provided with two X-shaped slide rails 33, which are symmetrically arranged at the bottom of the lifting frame 32 and connected by a first rotating shaft 34. Specifically, the X-shaped slide rail 33 includes a first slide rail 331 and a second slide rail 332, which are arranged intersectingly to form an X shape. The first slide rail 331 and the second slide rail 332 are rotatably connected by a first rotating shaft 34. The base 1 is provided with a lower slide track 11, which has a cylindrical rod-shaped structure. A first roller 3311 is rotatably provided at the bottom of the first slide rail 331. The first roller 3311 is located on the outside of the lower slide track 11 and is slidably connected to it, so that the first roller 3311 slides back and forth along the length of the lower slide track 11. The top of the first slide rail 331 is hinged to the bottom of the lifting frame 32. The bottom of the lifting frame 32 is provided with an upper slide rail 321, and the top of the second slide rail 332 is rotatably provided with a second roller 3321. The second roller 3321 is located on the outside of the upper slide rail 321 and is slidably connected to it, so that the second roller 3321 slides back and forth along the length of the upper slide rail 321. The bottom of the second slide rail 332 is hinged to the top of the base 1. A fixing frame 333 is connected between the two X-shaped slide rails 33 to fix the two X-shaped slide rails 33 together and improve the strength and rigidity between them.

[0022] In addition, to ensure operational safety and accuracy, the lifting assembly 3 is also equipped with a position sensor and limit switches. These sensors and switches are mounted on the base 1 and can monitor the material's conveying position in real time and prevent it from exceeding its travel range. The position sensor and limit switches are existing technologies, and their models and placement are designed according to the design height; therefore, they will not be described further here.

[0023] When the height of the lifting assembly 3 needs to be adjusted, the first drive motor 21 is started. The output shaft of the first drive motor 21 rotates, driving the first driving wheel 22 to rotate. The rotation of the first driving wheel 22 drives the first driven wheel 23 to rotate through the first transmission belt 24. The rotation of the first driven wheel 23 drives the screw jack 31 to move, so that the screw 311 of the screw jack 31 rotates, thereby driving the nut 312 and the lifting frame 32 fixedly connected to the nut 312 to move in the vertical direction, realizing the up and down lifting of the lifting assembly 3. During the lifting process of the lifting frame 32, the first slide rail 331 and the second slide rail 332 rotate and open and close relative to each other. The first roller 3311 and the second roller 3321 slide back and forth along the length direction of the lower slide rail 11 and the upper slide rail 321, respectively, which improves the stability of the structure.

[0024] like Figure 4 and Figure 5 As shown, a conveying assembly 4 is provided at the top of the lifting assembly 3. The conveying assembly 4 includes multiple rollers 41 rotatably mounted on the top of the lifting frame 32. The multiple rollers 41 are evenly distributed along the length direction of the lifting frame 32, and the axial direction of the rollers 41 is perpendicular to the length direction of the lifting frame 32. The rotation of the multiple rollers 41 is used to drive the material placed on them to be conveyed forward. A second drive motor 42 is fixedly provided at the bottom of the lifting frame 32. A second drive wheel 43 is fixedly provided on the output shaft of the second drive motor 42. A second driven wheel 44 is fixedly provided at one end of the roller 41. A second transmission belt 45 is sleeved between the second drive wheel 43 and the second driven wheel 44 located at the end. Preferably, the second driven wheel 44 is a double-row wheel, and two adjacent second driven wheels 44 are connected by a third transmission belt 46. The double-row wheel can be a sprocket or a synchronous belt pulley, and the corresponding third transmission belt 46 can be a chain or a synchronous belt, which is not limited here. The second driven wheel 44 located in the middle is connected to the adjacent second driven wheels 44 on both sides by the third transmission belt 46.

[0025] The second drive motor 42 is started, and the output shaft of the second drive motor 42 rotates, driving the second drive wheel 43 to rotate. The rotation of the second drive wheel 43 drives the second driven wheel 44 to rotate through the second transmission belt 45. Since the multiple second driven wheels 44 are connected by multiple third transmission belts 46, the multiple second driven wheels 44 rotate synchronously, thereby driving the multiple rollers 41 fixed to them to rotate synchronously, so as to transport materials.

[0026] like Figure 6As shown, the output end of the conveying assembly 4 is equipped with an anti-drop mechanism 5 to prevent materials from falling off at the end. The anti-drop mechanism 5 includes a first cylinder 51 located at the bottom of the lifting frame 32. The fixed end of the first cylinder 51 is hinged to the lifting frame 32, and the movable end of the first cylinder 51 is connected to a first swing plate 52. One end of the first swing plate 52 is hinged to the movable end of the first cylinder 51, and the other end of the first swing plate 52 is fixedly connected to a second swing plate 54 via a second rotating shaft 53. Specifically, the other end of the first swing plate 52 is fixedly connected to the outer periphery of the second rotating shaft 53, and one end of the second swing plate 54 is also fixedly connected to the outer periphery of the second rotating shaft 53. The first swing plate 52 and the second swing plate 54 form an obtuse angle. When the first cylinder 51 retracts, it drives the first swing plate 52 and the second swing plate 54 to rotate axially around the second rotating shaft 53 until the second swing plate 54 is vertically positioned at the end of the conveying assembly 4. This serves to block the material on the roller 41 from continuing to move forward, preventing the material from falling from above the roller 41 to the lower part. When the first cylinder 51 extends, the second swing plate 54 is horizontally positioned and no longer blocks the material being conveyed on the roller 41, allowing the material to be conveyed normally.

[0027] This utility model discloses a liftable conveyor roller conveyor. When it is necessary to convey material from a higher conveyor platform to a lower conveyor platform, the first drive motor 21 is activated. The output shaft of the first drive motor 21 rotates, driving the first driving wheel 22 to rotate, which in turn drives the first driven wheel 23 to rotate via the first transmission belt 24. The rotation of the first driven wheel 23 drives the screw jack 31 fixedly connected to it to operate. The screw 311 of the screw jack 31 rotates, which in turn drives the nut 312 and the lifting frame 32 fixedly connected to the nut 312 to move vertically upward until they are level with the higher conveyor platform. Then, the first drive motor 21 is stopped; the first cylinder 51 is retracted, and the first cylinder 51 drives the first swing plate 52 and the second swing plate 54 to rotate around the axis of the second rotating shaft 53 until the second swing plate 54 is vertically positioned at the end of the conveying assembly 4 to block the material on the roller 41 from continuing to move forward and prevent the material from falling from the top of the roller 41 to the bottom; then, the second drive motor 42 is started, and the output shaft of the second drive motor 42 rotates to drive the second driving wheel 43 to rotate. The rotation of the second driving wheel 43 drives the second driven wheel 44 to rotate through the second transmission belt 45. The second driven wheels 44 are connected by multiple third transmission belts 46, so the multiple second driven wheels 44 rotate synchronously, thereby driving the multiple rollers 41 fixed to them to rotate synchronously, thus conveying materials until all the materials to be conveyed are conveyed onto the rollers 41, after which the second drive motor 42 stops. The anti-drop mechanism 5 set at the output end of the conveying assembly 4 can effectively prevent materials from falling off the rollers 41. Then the first drive motor 21 is restarted, causing it to rotate in the opposite direction, and driving the lifting frame 32 to move vertically downwards until it is level with the lower conveying platform, and then... Stop the first drive motor 21; extend the first cylinder 51, which drives the first swing plate 52 and the second swing plate 54 to rotate around the second rotating shaft 53 until the second swing plate 54 is horizontal and no longer obstructs the material being conveyed on the roller 41; then, restart the second drive motor 42, which drives multiple rollers 41 to rotate, thereby conveying multiple materials on the rollers 41 to the lower conveyor platform, completing the automatic conveying of materials from the higher conveyor platform to the lower conveyor platform without manual handling, reducing labor intensity and improving work efficiency. Similarly, when it is necessary to convey materials from the lower conveyor platform to the higher conveyor platform, the operation process is similar to the above process and will not be repeated here.

[0028] While this utility model discloses preferred embodiments to achieve the above objectives, it is not intended to limit the structural features of this utility model. Anyone skilled in the art should know that any easily conceivable variations or modifications are possible under the technical spirit of this utility model and are covered by the patent claims of this utility model.
