Description

Technical Field

[0001] This utility model relates to the field of leveling machine technology, and in particular to the leveling structure of an adjustable feeding leveling machine. Background Technology

[0002] A screed is a mechanical device used to flatten materials. Its screed structure mainly includes upper and lower screed rollers, a gap adjustment mechanism, a transmission system, a support and guiding mechanism, and a control system. These parts work together, using the upper and lower screed rollers to compress and transport the material, the transmission system to provide power, the support and guiding mechanism to ensure stable operation, and the control system to automate the process, thereby achieving the purpose of leveling the material.

[0003] In existing technologies, some leveling structures allow materials to be conveyed between upper and lower rollers. The upper and lower rollers apply a certain pressure to the material, gradually flattening the uneven parts. However, since the upper and lower rollers are fixed in a designated position, when dealing with materials of different thicknesses, the fixed positions of the rollers may prevent them from contacting the material or may cause the material to be over-compressed, resulting in material damage. Consequently, product quality becomes unstable, and overall production efficiency is reduced. Therefore, to address these shortcomings, an adjustable feeding leveling machine with a leveling structure has been proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable feeding leveling machine with a leveling structure. This design aims to improve the problems in existing technologies where fixed upper and lower rollers lead to poor contact or excessive compression when dealing with materials of different thicknesses, resulting in material damage, unstable product quality, and low production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] The leveling structure of the adjustable feeding leveling machine includes a housing. A receiving frame is fixedly connected to the top front side of the housing. An electric push rod is fixedly connected to both the front and rear sides of the top of the receiving frame. A sliding plate is fixedly connected to the drive end of the electric push rod. Multiple telescopic rods are fixedly connected to the bottom end of the sliding plate. A strong spring is sleeved on the outside of the telescopic rod. A sliding block is fixedly connected to the bottom end of the telescopic rod. Multiple sliding holes are opened on both the front and rear sides of the receiving frame. Multiple upper rollers are slidably connected inside the receiving frame. Multiple lower rollers are rotatably connected inside the receiving frame. Adjustment components for connection are fixedly connected to the right ends of both the front and rear sides of the receiving frame.

[0007] Furthermore, an electric push rod 2 is fixedly connected to the front left end of the box body. Multiple connecting blocks 1 are fixedly connected to the outside of the electric push rod 2. Connecting rod 1 is rotatably connected inside the connecting blocks 1. Three feeding blocks are rotatably connected to the far sides of the multiple connecting rods 1. Three connecting blocks 2 are fixedly connected to the outside of the drive end of the electric push rod 2. Connecting rod 2 is rotatably connected inside the connecting blocks 2. The far sides of the multiple connecting rods 2 are respectively rotatably connected to the inside of the near sides of the three feeding blocks.

[0008] Furthermore, the adjustment assembly includes connecting blocks, with adjacent sides of two connecting blocks respectively fixedly connected to the front and rear right ends of the receiving frame, and adjacent sides of the two connecting blocks rotatably connected to connecting plates, and adjacent sides of the two connecting plates rotatably connected to multiple feeding rollers, and the bottom right inner wall of the receiving frame is rotatably connected to two bolts, with moving blocks connected to the external threads of the bolts.

[0009] Furthermore, a support frame is fixedly connected to the bottom of the box, and a control block is fixedly connected to the front of the box.

[0010] Furthermore, receiving holes are provided inside the top ends of both the front and rear sides of the receiving frame, and the outside of the sliding plate is slidably connected to the inside of the receiving holes.

[0011] Furthermore, one end of the strong spring is fixedly connected to the inside side of the sliding hole, and the other end of the strong spring is fixedly connected to the top of the sliding block.

[0012] Furthermore, the outer side of the sliding block is slidably connected to the inside of the sliding hole, and the front and rear sides of the upper roller are respectively rotatably connected to the adjacent sides of the two sliding blocks.

[0013] Furthermore, two movable holes are opened inside the bottom right side of the receiving frame. The outer side of the movable block is slidably connected to the inside of the movable holes. The top end of the bolt is rotatably connected to the top end inside the movable holes. The outer right ends of the two movable blocks are rotatably connected to the front and rear ends of the left side of the connecting plate.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the electric push rod drives the telescopic rod, which in turn causes the sliding block to move the upper roller, thus realizing the adjustable position of the upper roller. This allows the feeding leveling machine to adapt to materials of different thicknesses, ensuring that the material can be effectively leveled between the upper and lower rollers. Furthermore, the telescopic spring sleeved on the outside of the telescopic rod can automatically adjust the degree of compression according to the pressure of the material, thereby making the pressure applied by the upper roller to the material more precise, improving the quality and stability of the leveling effect and production efficiency.

[0016] 2. In this utility model, the electric push rod 2 drives the connecting rod 1 at the top to move, which in turn causes the connecting rod 2 at the bottom of the electric push rod 2 to move, causing the material feeding block to expand outward or contract inward. This allows the equipment to quickly switch to adapt to materials of different widths, and the appropriate adjustment of the material feeding block width can reduce the shaking of the material during the conveying process and increase the stability of the material conveying.

A receiving frame 4 is fixedly connected to the top front of the housing 1, with receiving holes 5 on both the front and rear top sides of the receiving frame 4, providing space for the movement of subsequent components. Electric push rods 6 are fixedly connected to the top front and rear sides of the receiving frame 4, providing power. A sliding plate 7 is fixedly connected to the drive end of the electric push rod 6, and the sliding plate 7 is slidably connected to the inside of the receiving holes 5, providing smooth movement. Multiple telescopic rods 8 are fixedly connected to the bottom of the sliding plate 7, with a strong spring 9 sleeved on the outside of each telescopic rod 8, allowing the springs 9 to extend and retract according to different conditions.

[0025] A sliding block 10 is fixedly connected to the bottom end of the telescopic rod 8. Multiple sliding holes 11 are provided on both the front and rear sides of the receiving frame 4. One end of a powerful spring 9 is fixedly connected to the inside of one sliding hole 11, and the other end is fixedly connected to the top of the sliding block 10. The outside of the sliding block 10 is slidably connected to the inside of the sliding hole 11, allowing for flexible and stable sliding. Multiple upper rollers 12 are slidably connected inside the receiving frame 4. The front and rear sides of each upper roller 12 are rotatably connected to the adjacent sides of two sliding blocks 10, ensuring a tight fit. Multiple lower rollers 13 are rotatably connected inside the receiving frame 4. The lower rollers 13 work together with the upper rollers 12 to level the material. Adjustment components for connection are fixedly connected to the right ends of both the front and rear sides of the receiving frame 4. Each adjustment component includes a connecting block 14, with the adjacent sides of two connecting blocks 14 fixedly connected to the right ends of both the front and rear sides of the receiving frame 4.

[0026] Connecting plates 15 are rotatably connected to adjacent sides of the two connecting blocks 14. Multiple feeding rollers 16 are rotatably connected to adjacent sides of the two connecting plates 15. The feeding rollers 16 are driven by a motor and a reducer, providing sufficient power to ensure smooth material feeding. Two bolts 17 are rotatably connected to the inner wall of the bottom right side of the receiving frame 4. Moving blocks 18 are threaded onto their external parts. The right ends of the two moving blocks 18 are rotatably connected to the front and rear ends of the left side of the connecting plate 15, respectively. Two movable holes 19 are opened inside the bottom right side of the receiving frame 4. The external parts of the moving blocks 18 are slidably connected to the inside of the movable holes 19, and the tops of the bolts 17 are rotatably connected to the top of the inside of the movable holes 19.

[0027] Reference Figure 1 , Figure 2 and Figure 4Electric push rod 20 is fixedly connected to the front left end of box 1. Electric push rod 20 provides power and multiple connecting blocks 21 are fixedly connected to its exterior. Connecting rod 22 is rotatably connected inside connecting block 21. Three feeding blocks 23 are rotatably connected to the far side of multiple connecting rods 22. Three connecting blocks 24 are fixedly connected to the drive end of electric push rod 20. Connecting rod 25 is rotatably connected inside connecting block 24. The far side of multiple connecting rods 25 is rotatably connected to the interior of the near side of the three feeding blocks 23.

[0028] Working Principle: First, when leveling materials of different thicknesses is required, the electric push rod 6 is activated. The drive end of the electric push rod 6 drives the sliding plate 7 to slide within the receiving hole 5, and the sliding plate 7 in turn drives the telescopic rod 8 to move. The telescopic rod 8 drives the sliding block 10 to slide within the sliding hole 11. Since the front and rear sides of the upper roller 12 are respectively rotatably connected to the adjacent sides of the two sliding blocks 10, the movement of the sliding blocks 10 drives the upper roller 12 to move, realizing the adjustable position of the upper roller 12. At the same time, the strong spring 9 outside the telescopic rod 8 automatically adjusts the degree of compression according to the pressure of the material. When the material is thicker, the strong spring 9 is compressed more, and the upper roller 12 moves upward a certain distance to ensure that the material can be effectively leveled between the upper roller 12 and the lower roller 13; when the material is thinner, the strong spring 9 extends, and the upper roller 12 moves downward a certain distance, making the pressure applied by the upper roller 12 to the material more precise, improving the quality and stability of the leveling effect and production efficiency.

[0029] Secondly, when it is necessary to accommodate materials of different widths, the electric push rod 20 is activated. The electric push rod 20 drives the top connecting rod 22 to move, and the movement of the connecting rod 22 causes the connecting rod 25 at the bottom of the electric push rod 20 to move. Since the outer sides of the multiple connecting rods 25 are rotatably connected to the inner sides of the three feeding blocks 23, the movement of the connecting rods 25 causes the feeding blocks 23 to expand outwards or contract inwards, allowing the equipment to quickly switch to accommodate materials of different widths. Furthermore, appropriate adjustment of the feeding block 23 width can reduce material vibration during conveying and increase the stability of material conveying.

[0030] Finally, when the position of the feed roller 16 needs to be adjusted, rotate bolt 17. Rotation of bolt 17 causes the threaded movable block 18 to slide within the movable hole 19. Since the right ends of the two movable blocks 18 are rotatably connected to the front and rear ends of the left side of the connecting plate 15, the sliding of the movable blocks 18 causes the connecting plate 15 to rotate. Because multiple feed rollers 16 are rotatably connected to adjacent sides of the two connecting plates 15, the rotation of the connecting plates 15 causes the feed rollers 16 to move, thus adjusting the position of the feed rollers 16. The feed rollers 16 move via a motor and reducer to ensure smooth material feeding.

[0031] 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.
