Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a scissor lift conveyor. Background Technology

[0002] Material conveying is an indispensable and crucial process in many fields, including industrial production, warehousing and logistics, and cargo loading and unloading. Currently, the market offers a wide variety of material conveying equipment, but most have certain limitations. For example, many conveying devices have a fixed height, making them unable to be flexibly adjusted to different operating scenarios and material conveying needs. When needing to connect with equipment or workstations of different heights, additional auxiliary tools are often required, which is not only cumbersome to operate but also reduces work efficiency.

[0003] Meanwhile, during material conveying, the lack of effective limiting devices makes materials prone to lateral deviation. This can range from affecting the smoothness of the conveying process to causing materials to fall, become damaged, or even lead to safety accidents. Traditional conveying equipment is particularly unsuitable for materials of different sizes, making it difficult to ensure stable conveying of various materials. Furthermore, the inadequate design of the drive mechanism in some conveying equipment results in unstable and inefficient power transmission, which also affects the conveying effect and the equipment's lifespan.

[0004] Therefore, it is of great significance to provide a scissor lift conveyor that can solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a scissor lift conveyor to solve the problem.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0032] Please see Figure 1-2 This utility model provides a technical solution for a scissor lift conveyor:

[0033] A scissor lift conveyor mainly consists of a scissor lifting mechanism, a limit mechanism, a conveying mechanism, and a drive mechanism.

[0034] The scissor lift mechanism is the core component for adjusting the equipment height. It includes a bottom support 1, a first hinge rod 5, a second hinge rod 25, and a lifting plate 19. The first hinge rod 5 and the second hinge rod 25 are hinged together at their midpoints via a hinge shaft 6, forming a scissor-like structure. The top of the first hinge rod 5 is hinged to the bottom support 1, and an upper sliding wheel 8 is installed at its bottom. The upper sliding wheel 8 can slide within a groove on the lifting plate 19, allowing the bottom of the first hinge rod 5 to move flexibly with the lifting motion. The top of the second hinge rod 25 is hinged to the lifting plate 19, and a lower sliding wheel 2 is installed at its bottom. The lower sliding wheel 2 can slide within a groove on the bottom support 1, providing support for the bottom of the second hinge rod 25. A connecting frame 3 is fixedly connected to the bottom of the second hinge rod 25. The connecting frame 3 is hinged to one end of a hydraulic strut 4, and the telescopic end of the hydraulic strut 4 is hinged to the hinge shaft 6. When the hydraulic strut 4 extends or retracts, it pushes the hinge shaft 6 to move, thereby causing hinge rod 5 and hinge rod 25 to rotate around their respective hinge points, thus raising or lowering the lifting plate 19. The hydraulic strut 4 can be a hydraulic cylinder or an electric push rod, providing appropriate driving force according to actual needs.

[0035] The conveying mechanism is used to carry and transport materials, and includes a frame 14, conveying rollers 15, and roller fixing brackets 17. The frame 14 is fixedly installed on the top of the lifting plate 19, providing support for the entire conveying mechanism. The conveying rollers 15 are evenly installed on the frame 14 through the roller fixing brackets 17. The conveying rollers 15 are powered rollers, and their surfaces are provided with anti-slip textures or rubber coatings to enhance the friction between them and the materials and prevent the materials from slipping during the conveying process.

[0036] The limiting mechanism is used to laterally limit the material and ensure the stability of material conveying. It includes a slide rail 22, a limiting wheel fixing frame 23, a lead screw 21, and a limiting wheel 16. The slide rail 22 is fixedly installed on the top of the lifting plate 19. The slide rail 22 can be a linear guide rail or a T-slot guide rail to ensure the smooth sliding of the limiting mechanism. A slider 24 is installed at the bottom of the limiting wheel fixing frame 23. The slider 24 is slidably connected to the slide rail 22, allowing the limiting wheel fixing frame 23 to move smoothly along the slide rail 22. The lead screw 21 is rotatably connected between the front and rear sides of the frame 14. A handwheel 7 is installed at one end of the lead screw 21 for easy rotation by the operator. There are two limiting wheel fixing frames 23. A lead screw slider 20 is fixedly connected to the bottom of each frame. The lead screw 21 has two opposite threads, which are threadedly connected to the two lead screw sliders 20 respectively. When the handwheel 7 is turned, causing the lead screw 21 to rotate, the two lead screw sliders 20 will drive the two limit wheel fixing frames 23 to move synchronously in opposite directions due to the opposite directions of the two threads, thereby adjusting the distance between the limit wheels 16. The limit wheels 16 are installed on the top of the limit wheel fixing frames 23 through the limit wheel fixing parts 18 and are spaced apart from the conveying rollers 15. The limit wheels 16 are made of rubber or nylon, which have a certain degree of elasticity, so as to not only play a limiting role, but also avoid damaging the surface of the material, and can effectively adjust the lateral position of the conveyed items.

[0037] The drive mechanism provides power for the rotation of the conveyor roller 15 and includes a motor 10, a drive sprocket 9, and a transmission sprocket 12. The motor 10 is fixedly mounted on one side of the bottom of the frame 14. The motor 10 can be a servo motor or a geared motor, providing stable speed and torque for the conveyor roller 15. The output shaft of the motor 10 is connected to the drive sprocket 9, transmitting power to it. The transmission sprocket 12 is a double-layer sprocket, installed at the end of the conveyor roller 15. The drive sprocket 9 is connected to one of the transmission sprockets 12 via a chain drive, and adjacent transmission sprockets 12 are connected via a transmission chain 13. Thus, the power from the motor 10 is sequentially transmitted to each conveyor roller 15 through the drive sprocket 9, chain, transmission sprocket 12, and transmission chain 13, enabling all conveyor rollers 15 to rotate synchronously and achieve material conveying. The double-layer sprocket design ensures the stability and reliability of the chain drive, avoiding problems such as chain skipping.

[0038] The working process of this utility model is as follows: Based on the required material conveying height, the lifting plate 19 is adjusted to a suitable height by controlling the extension and retraction of the hydraulic strut 4. Then, according to the material size, the handwheel 7 is turned, causing the lead screw 21 to rotate, which in turn moves the two limit wheel fixing frames 23, adjusting the distance between the limit wheels 16 to match the material size. The motor 10 is started, and the motor 10 drives the transmission sprocket 12 to rotate via the drive sprocket 9 and chain, thereby causing all the conveying rollers 15 to rotate. The material is placed on the conveying rollers 15 and conveyed forward under the drive of the conveying rollers 15. At the same time, the limit wheels 16 laterally limit the material, ensuring stable material conveying.

[0039] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
