Description

Technical Field

[0001] This application relates to the field of roller press technology, and more specifically, to a roller press feed adjustment plate. Background Technology

[0002] The feed regulating plate of the roller press is a key component in the roller press feeding system. It is mainly used to control the flow rate, speed and distribution of material entering between the two rollers of the roller press, and has an important impact on the stable operation of the roller press, grinding efficiency and product quality.

[0003] Patent CN215429323U discloses a feed adjustment plate for a roller press, comprising a feed plate, a fixed plate, a connecting rod, and an electric push rod. A limit plate is welded to the bottom surface of the feed plate, and a side plate is welded to the top surface. A rotating shaft is provided at one end of the limit plate, which is rotatably mounted on one end of the fixed plate via the rotating shaft. A sliding groove is provided on the fixed plate, and a limit shaft is provided on the limit plate. A support rod is rotatably mounted on the limit plate via the limit shaft. Limit shafts are provided at both ends of the connecting rod, which is slidably mounted within the sliding groove of the fixed plate via the limit shafts. By setting the connecting rod, which is movably connected to the limit shaft at the bottom of the feed plate via the support rod, and movably connected to the electric push rod via a connecting block, the user connects the electric push rod to the power supply. The electric push rod pushes the connecting rod forward within the sliding groove of the fixed plate, causing the connecting rod to move the support rod forward and lift the feed plate, increasing the tilt angle of the feed plate and thus accelerating the feeding speed.

[0004] In the aforementioned roller press feed adjustment plate, the feed plate, as a component that directly contacts the material, is prone to wear under the impact and friction of the material. Therefore, it needs to be inspected and replaced regularly to ensure the reliable operation of the feed adjustment function. However, the feed plate of the aforementioned roller press feed adjustment plate is connected to the rotating shaft and the fixed plate through a limiting plate. This connection structure creates a relatively fixed assembly relationship between the feed plate and the fixed plate. When the feed plate needs to be replaced due to wear, it is difficult to easily remove it from the fixed plate due to the constraints of the limiting plate, rotating shaft, and other components. The replacement process often requires the disassembly of multiple related components, which is cumbersome and time-consuming. Summary of the Invention

[0005] The purpose of this application is to provide a roller press feed adjustment plate that can solve the technical problems mentioned in the background art.

[0006] This application provides a roller press feed adjustment plate, including a feed plate, a movable frame, and a fixed frame. The feed plate is detachably snapped onto the movable frame. One end of the movable frame is movably hinged to one end of the fixed frame via a hinge shaft. The fixed frame is provided with an angle adjustment component. The output end of the angle adjustment component is drivenly connected to the end of the movable frame away from the hinge shaft, and is used to drive the movable frame to rotate around the hinge shaft to adjust the included angle between the movable frame and the fixed frame.

[0007] Furthermore, the movable frame includes a first side plate, a second side plate, and a connecting plate. The first side plate and the second side plate are arranged in parallel and spaced apart. The two ends of the connecting plate are respectively welded between the opposite inner side walls of the first side plate and the second side plate. The feeding plate is detachably snapped onto the inner side of the first side plate and the second side plate and is located above the connecting plate. Both the first side plate and the second side plate have a portion protruding from the top surface of the feeding plate.

[0008] Furthermore, the inner wall of the first side plate is provided with a first insertion groove along the length direction, and the inner wall of the second side plate is provided with a second insertion groove along the length direction. The first insertion groove and the second insertion groove are parallel and opposite to each other. The two sides of the feeding plate are respectively inserted into the first insertion groove and the second insertion groove. The upper end groove wall of the first insertion groove and the second insertion groove are provided with a snap-fit ​​groove. The upper end of the feeding plate is provided with snap-fit ​​parts that are adapted to the snap-fit ​​grooves. The snap-fit ​​parts are snapped into the corresponding snap-fit ​​grooves.

[0009] Furthermore, a first limiting block is fixedly provided at the bottom of the feeding plate, and a second limiting block is fixedly provided at the top of the connecting plate. When the snap-fit ​​part is snapped into the corresponding snap-fit ​​groove, the first limiting block and the second limiting block abut against each other.

[0010] Furthermore, the fixing frame includes a first T-shaped plate, a second T-shaped plate, and a plurality of connecting rods. The first T-shaped plate and the second T-shaped plate are parallel and inverted. The plurality of connecting rods are evenly distributed between the first T-shaped plate and the second T-shaped plate along their length direction. The two ends of each connecting rod are respectively welded to the opposite inner sidewalls of the first T-shaped plate and the second T-shaped plate. The two ends of the hinge shaft are respectively fixedly connected to the opposite inner sides of the upper ends of the first T-shaped plate and the second T-shaped plate. The upper ends of the first side plate and the second side plate are each provided with a connecting through hole adapted to the hinge shaft. The hinge shaft movably passes through the connecting through hole on the first side plate and the second side plate.

[0011] Furthermore, the angle adjustment assembly includes an electric push rod and a mounting base. The piston rod end of the electric push rod is movably hinged to the bottom of the connecting plate via a first pin, and the cylinder end of the electric push rod is movably hinged to the mounting base via a second pin. The two ends of the mounting base are respectively fixedly connected between the opposite inner sidewalls of the first T-shaped plate and the second T-shaped plate.

[0012] Furthermore, the top surface of the feeding plate is uniformly provided with multiple buffer grooves along the material conveying direction, and the cross-section of the buffer grooves is trapezoidal.

[0027] like Figure 1-3As shown, this application provides a feed adjustment plate for a roller press, including a feed plate 1, a movable frame 2, and a fixed frame 3. The feed plate 1 and the movable frame 2 are detachably snapped together. One end of the movable frame 2 is movably hinged to one end of the fixed frame 3 via a hinge shaft 4. The fixed frame 3 is provided with an angle adjustment component 5. The output end of the angle adjustment component 5 is connected to the end of the movable frame 2 away from the hinge shaft 4, and is used to drive the movable frame 2 to rotate around the hinge shaft 4 to adjust the included angle between the movable frame 2 and the fixed frame 3. The detachable snap-fit ​​connection between the feed plate 1 and the movable frame 2 enables flexible installation and replacement of the feed plate 1. One end of the movable frame 2 is connected via a hinge shaft 4. The hinge shaft 4 is movably hinged to the fixed frame 3, allowing the movable frame 2 to rotate around the hinge shaft 4. The output end of the angle adjustment component 5 on the fixed frame 3 is connected to the end of the movable frame 2 away from the hinge shaft 4. When the angle adjustment component 5 is activated, it drives the movable frame 2 to rotate around the hinge shaft 4, thereby changing the angle between the movable frame 2 and the fixed frame 3, ultimately adjusting the tilt angle of the feed plate 1 to adapt to different feeding requirements. Compared with the prior art, the feed plate 1 and the movable frame 2 are designed as a detachable snap-fit ​​structure, which facilitates quick disassembly and assembly when the feed plate 1 needs to be replaced due to wear, reducing maintenance difficulty and downtime.

[0028] like Figure 1-3 As shown, the movable frame 2 includes a first side plate 21, a second side plate 22, and a connecting plate 23. The first side plate 21 and the second side plate 22 are arranged in parallel and spaced apart. The two ends of the connecting plate 23 are respectively welded between the opposite inner side walls of the first side plate 21 and the second side plate 22. The feeding plate 1 is detachably snapped onto the inner side of the first side plate 21 and the second side plate 22 and located above the connecting plate 23. Both the first side plate 21 and the second side plate 22 have a portion protruding from the top surface of the feeding plate 1. The frame structure formed by welding the first side plate 21, the second side plate 22, and the connecting plate 23 has high strength and can stably support the feeding plate 1 and withstand the impact of materials. The lateral limiting of the feeding plate 1 by the first side plate 21 and the second side plate 22 and the enclosure formed by the portion protruding from the top surface can effectively constrain the material conveying path and prevent material leakage.

[0029] like Figure 3As shown, the inner wall of the first side plate 21 is provided with a first insertion groove 211 along the length direction, and the inner wall of the second side plate 22 is provided with a second insertion groove 221 along the length direction. The first insertion groove 211 and the second insertion groove 221 are parallel and opposite to each other. The two sides of the feeding plate 1 are respectively inserted into the first insertion groove 211 and the second insertion groove 221. The upper end groove walls of the first insertion groove 211 and the second insertion groove 221 are provided with snap-fit ​​grooves 6. The upper end of the feeding plate 1 is provided with snap-fit ​​parts 11 that are adapted to the snap-fit ​​grooves 6. The snap-fit ​​parts 11 are snapped into the corresponding snap-fit ​​grooves 6. The fit between the groove and the side of the feeding plate 1 provides precise installation positioning for the feeding plate 1, ensuring the consistency of the assembly position of the feeding plate 1; the snap-fit ​​structure of the snap-fit ​​groove 6 and the snap-fit ​​part 11 further enhances the stability of the feeding plate 1 installation and can effectively resist the external force generated by the impact of materials; the combination of plug-in and snap-fit ​​connection method not only ensures the reliable fixation of the feeding plate 1 during operation, but also simplifies the disassembly and assembly process of the feeding plate 1. When the feeding plate 1 is worn and needs to be replaced, the snap-fit ​​part 11 and the snap-fit ​​groove 6 can be quickly separated and the feeding plate 1 can be pulled out, which greatly improves the replacement efficiency and reduces downtime.

[0030] like Figure 2 and Figure 3 As shown, a first limiting block 12 is fixed at the bottom of the feeding plate 1, and a second limiting block 231 is fixed at the top of the connecting plate 23. When the snap-fit ​​part 11 is snapped into the corresponding snap-fit ​​groove 6, the first limiting block 12 and the second limiting block 231 abut against each other. The abutting cooperation between the first limiting block 12 and the second limiting block 231 can share the vertical force borne by the snap-fit ​​part 11, prevent the snap-fit ​​part 11 from deforming or being damaged due to long-term stress, and extend the service life of the snap-fit ​​structure.

[0031] like Figure 1 and Figure 2As shown, the fixing frame 3 includes a first T-shaped plate 31, a second T-shaped plate 32, and multiple connecting rods 33. The first T-shaped plate 31 and the second T-shaped plate 32 are parallel and inverted. The multiple connecting rods 33 are evenly distributed between the first T-shaped plate 31 and the second T-shaped plate 32 along their length direction. The two ends of each connecting rod 33 are welded to the opposite inner sidewalls of the first T-shaped plate 31 and the second T-shaped plate 32, respectively. The two ends of the hinge shaft 4 are fixedly connected to the opposite inner sides of the upper ends of the first T-shaped plate 31 and the second T-shaped plate 32, respectively. The upper ends of the first side plate 21 and the second side plate 22 are both opened. There is a connecting through hole adapted to the hinge shaft 4, and the hinge shaft 4 moves through the connecting through hole on the first side plate 21 and the second side plate 22; the frame structure formed by welding the first T-shaped plate 31, the second T-shaped plate 32 and multiple equally spaced connecting rods 33 has strong overall rigidity and good stability, and can effectively bear the load of the movable frame 2 and the material transfer; the inverted T-shaped plate structure saves installation space and provides a stable installation foundation for the hinge shaft 4; the movable fit design between the hinge shaft 4 and the connecting through hole ensures the flexibility of the rotation of the movable frame 2, and makes the angle adjustment process smooth and stable.

[0032] like Figure 1 and Figure 2 As shown, the angle adjustment assembly 5 includes an electric push rod 51 and a mounting base 52. The piston rod end of the electric push rod 51 is movably hinged to the bottom of the connecting plate 23 via a first pin, and the cylinder end of the electric push rod 51 is movably hinged to the mounting base 52 via a second pin. The two ends of the mounting base 52 are respectively fixedly connected between the opposite inner sidewalls of the first T-shaped plate 31 and the second T-shaped plate 32. When the electric push rod 51 extends or retracts, the linear motion can be converted into the rotational motion of the movable frame 2 around the hinge axis 4 by means of the hinge structure of the two pins, thereby driving the angle between the movable frame 2 and the fixed frame 3 to change, and realizing the adjustment of the tilt angle of the feeding plate 1.

[0033] like Figure 2 and Figure 3 As shown, multiple buffer grooves 13 are evenly arranged on the top surface of the feeding plate 1 along the material conveying direction. The cross-section of the buffer groove 13 is trapezoidal. When the material falls on the feeding plate 1, some material will remain in the buffer groove 13. The direct impact force of subsequent materials can be reduced by the guidance of the groove wall of the buffer groove 13 and the buffering effect of the material in the buffer groove 13, thereby extending the service life of the feeding plate 1.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
