Abstract
Description
Technical Field
[0001] This utility model relates to screening device technology, specifically a roller screen particle size adjustment sliding mechanism. Background Technology
[0002] Roller screens are common screening equipment, mainly used in industries such as mining, building materials, chemicals, and food for particle size classification of materials. Their working principle involves rotating rollers that move the material across their surface. Material smaller than the screen openings passes through and falls, while material larger than the openings is discharged from one end of the roller. Roller screens are typically designed with fixed screen opening sizes to accommodate specific production needs.
[0003] Traditional roller screens are designed and manufactured with fixed screen aperture sizes. This means that once a roller screen is put into production, its screening particle size cannot be changed. This limits the flexibility of the equipment and makes it unable to adapt to production tasks with different particle size requirements. Because the screening particle size is not adjustable, when the particle size of the material needs to be changed during production, the entire roller or the screening equipment must be replaced. This not only increases production costs but may also lead to production interruptions and reduce production efficiency.
[0004] Therefore, we propose a roller screen particle size adjustment sliding mechanism to solve the problems encountered above. Utility Model Content
[0005] In view of the shortcomings of the existing technology, this utility model provides a roller screen particle size adjustment sliding mechanism to solve the problems mentioned in the background art.
[0006] The purpose of this utility model can be achieved through the following technical solution: it includes two lower base slide rails, and two upper guide light rods are fixedly connected inside each of the two lower base slide rails;
[0007] The adjustment assembly includes multiple sliding bearing seats that are slidably connected to the two corresponding upper guide rods. The upper parts of two adjacent sliding bearing seats that are close to each other are threaded with the same positioning bolt, and the bottom parts of two adjacent sliding bearing seats that are close to each other are threaded with the same adjustment bolt.
[0008] A vibration assembly includes a dual-axis motor fixedly connected to a sliding bearing seat on the rear side, a roller fixedly connected to the front end of the dual-axis motor, a cam fixedly connected to the rear end of the dual-axis motor, a spring fixedly connected to the bottom of the sliding bearing seat, and a vibration block fixedly connected to the bottom end of the spring.
[0009] The limiting component includes two fixed blocks fixedly connected to both sides of the vibrating block, and a limiting post fixedly connected to the top of each of the two fixed blocks. Limiting holes are opened on both the left and right sides of the bottom of the sliding bearing seat.
[0010] Preferably, the limiting post is slidably connected through the corresponding limiting hole, the front end of the vibrating block abuts against the outside of the corresponding roller, and the rear side of the vibrating block abuts against the outside of the corresponding cam.
[0011] Preferably, the left side of each of the two lower base slide rails abuts against a limiting block, and the front end of the roller is rotatably connected to a sliding bearing seat located on the front side.
[0012] Preferably, the lower base slide rail is concave, the roller is helical, and the vibrating block is concave.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. By setting the adjustment components, the roller screen can change the screening particle size during the production process, which improves the flexibility of the equipment and can adapt to production tasks with different particle size requirements. This avoids the situation where the entire roller or screening equipment must be replaced when the particle size of the material needs to be changed due to the inability to adjust the screening particle size. This not only reduces production costs but also avoids production interruption, further improving the production efficiency of the device.
[0015] 2. The design of the dual-axis motor, rollers, and cams in the vibration assembly can generate effective vibration, which helps to improve the flowability of materials and screening efficiency. The addition of the limiting component prevents excessive movement or collision during vibration, further increasing the safety and durability of the equipment. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Please see Figures 1-5 As shown, a roller screen particle size adjustment sliding mechanism includes two lower base slide rails 1, and two upper guide light rods 5 are fixedly connected inside each of the two lower base slide rails 1.
[0025] The adjustment assembly includes multiple sliding bearing seats 6 that are slidably connected to the two corresponding upper guide rods 5. The upper sides of adjacent sliding bearing seats 6 are threaded with the same positioning bolt 3, and the bottom sides of adjacent sliding bearing seats 6 are threaded with the same adjusting bolt 2. The adjustment assembly comprises multiple sliding bearing seats 6 that can slide along the upper guide rods 5. Each sliding bearing seat 6 is connected to its two sides by the positioning bolt 3 and the adjusting bolt 2. Rotation of the adjusting bolt 2 precisely controls the position of the sliding bearing seat 6, thereby adjusting the screening particle size. This design allows operators to make quick and precise adjustments according to different screening requirements without the need for complex tools or downtime.
[0026] The vibration assembly includes a dual-axis motor 7 fixedly connected to a sliding bearing seat 6 on the rear side. A roller 8 is fixedly connected to the front end of the dual-axis motor 7, and a cam 9 is fixedly connected to the rear end. A spring 10 is fixedly connected to the bottom of the sliding bearing seat 6, and a vibrating block 11 is fixedly connected to the bottom end of the spring 10. The roller 8 connected to the front end of the dual-axis motor 7 is spiral-shaped, which helps to evenly distribute the material on the screen surface. The cam 9 connected to the rear end of the motor contacts the vibrating block 11 at the bottom end of the spring 10. When the motor operates, the rotation of the cam 9 is converted into the reciprocating motion of the vibrating block 11. This vibration improves the flowability of the material and enhances the screening efficiency.
[0027] The limiting assembly includes two fixed blocks 12 fixedly connected to both sides of the vibrating block 11. Each fixed block 12 has a limiting post 13 fixedly connected to its top. Limiting holes 14 are formed on both the left and right sides of the bottom of the sliding bearing seat 6. The limiting posts 13 pass through the limiting holes 14 at the bottom of the sliding bearing seat 6, limiting the range of movement of the sliding bearing seat 6 during vibration. This design effectively prevents component damage or structural imbalance caused by excessive vibration, improving the safety and durability of the equipment.
[0028] The limiting post 13 is slidably connected through the corresponding limiting hole 14. The front end of the vibrating block 11 abuts against the outside of the corresponding roller 8, and the rear side of the vibrating block 11 abuts against the outside of the corresponding cam 9. The left side of each of the two lower base slide rails 1 abuts against the limiting block 4. The front end of the roller 8 is rotatably connected to the sliding bearing seat 6 located on the front side. The shape of the lower base slide rail 1 is concave, the shape of the roller 8 is spiral, and the shape of the vibrating block 11 is concave.
[0029] In the specific implementation of this utility model: First, the corresponding positioning bolt 3 and adjusting bolt 2 can be adjusted according to the requirements to adjust the spacing of the roller 8 to a suitable size. Then, the corresponding dual-axis motor 7 can be started synchronously. The dual-axis motor 7 can drive the rear cam 9 to rotate continuously. When the cam 9 rotates, it can intermittently touch the vibrating block 11, so that the vibrating block 11 drives the spring 10 to stretch and rebound, and can drive the two fixed blocks 12 and the limiting post 13 to move synchronously. The corresponding two limiting posts 13 can move back and forth in the limiting hole 14, and the front end of the vibrating block 11 can intermittently vibrate the roller 8.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
