Description

Technical Field

[0001] This utility model belongs to the technical field of headbox angle adjustment mechanism for papermaking machines that facilitates the adjustment of height and angle, specifically relating to a headbox angle adjustment mechanism for papermaking machines that facilitates the adjustment of height and angle. Background Technology

[0002] A headbox angle adjustment mechanism for paper machines, facilitating height and angle adjustment, typically consists of a base, a lifting assembly, an angle adjustment assembly, and a headbox mounting frame. The base serves as the supporting foundation. The lifting assembly, installed between the base and the headbox mounting frame, uses a hydraulic pump to vertically raise and lower the headbox mounting frame, thus precisely adjusting the headbox height. The angle adjustment assembly generally includes an angle drive. The headbox mounting frame is connected to the base or other fixed structure via a hinge point. The angle drive is connected to both the base and the headbox mounting frame. By driving the angle drive, the headbox mounting frame rotates around the hinge point, allowing for flexible adjustment of the headbox angle. This mechanism, through the coordinated action of the lifting assembly and the angle adjustment assembly, enables rapid and precise dynamic adjustment of the headbox height and angle to adapt to different papermaking process requirements, ensuring a uniform and stable flow of pulp to the wire section, improving paper quality and production efficiency.

[0003] The headbox angle adjustment mechanism for paper machines, which facilitates height and angle adjustment, has the second and third hydraulic cylinders installed at the lower end of the headbox. However, the second and third hydraulic cylinders are fixed at the upper end of the lifting platform, making it unsuitable for headboxes of different sizes and thus limiting its flexibility of use. Utility Model Content

[0004] The purpose of this invention is to provide a paper machine headbox angle adjustment mechanism that facilitates height and angle adjustment, in order to solve the problem in the prior art where the second and third hydraulic cylinders are installed at the lower end of the paper machine headbox, but are fixed at the upper end of the lifting platform, making it unsuitable for paper machine headboxes of different sizes, thus limiting its flexibility of use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a headbox angle adjustment mechanism for a paper machine that facilitates height and angle adjustment, comprising a base plate, a first hydraulic cylinder installed at the upper end of the base plate, the first hydraulic cylinder driving a lifting platform at the upper end to rise and fall, a third hydraulic cylinder installed at the right side of the upper end of the lifting platform, a slide groove provided at the inner side of the upper end of the lifting platform, a fixing rod fixed at the inner side of the slide groove, a movable plate installed at the inner side of the slide groove via the fixing rod, a second hydraulic cylinder installed at the upper end of the movable plate, a rotating shaft provided at the inner side of both the second and third hydraulic cylinders, an mounting plate fixed at the outer end face of the rotating shaft, connecting rods fixed at both ends of the lifting platform, a sleeve frame fixed at the other end of the connecting rod, and a fixing column sleeved inside the sleeve frame.

[0006] Preferably, the upper end of the mounting plate is provided with mounting holes at the four corners, and the mounting plate is installed to the headbox of the paper machine through the mounting holes and bolts.

[0007] Preferably, a lifting rod is provided inside the first hydraulic cylinder, and the first hydraulic cylinder drives the lifting platform to move up and down through hydraulic oil and the lifting rod.

[0008] Preferably, the fixed column is fixed to the ground, and during the lifting process, the lifting platform causes the socket frame to move along the outer wall of the fixed column.

[0009] Preferably, the height of the fixing column is less than the height of the mounting plate, and a fixing plate is fixed at the upper end of the fixing column.

[0010] Preferably, the rotating shaft is located inside the hydraulic rods of the third and second hydraulic cylinders, and the mounting plate can rotate around the rotating shaft as its center axis.

[0011] Preferably, when the hydraulic rods inside the third and second hydraulic cylinders are in the initial state, the two mounting plates are at the same height.

[0012] Preferably, the fixing rod is sleeved inside the movable plate, and the movable plate can move laterally along the fixing rod, and the position of the second hydraulic cylinder can be adjusted via the movable plate.

[0013] Compared with the prior art, this utility model provides a paper machine headbox angle adjustment mechanism that facilitates the adjustment of height and angle, and has the following beneficial effects:

[0014] The third hydraulic cylinder of this device is fixed to the lifting platform, and the second hydraulic cylinder is fixed at the upper end of the moving plate. The moving plate can move laterally along the fixed rod, thereby driving the second hydraulic cylinder to move. During the movement, it can be moved to the appropriate position according to the size of the paper machine headbox. This allows the angle adjustment mechanism to be installed with paper machine headboxes of different sizes, thereby increasing the flexibility of the angle adjustment mechanism.

[0015] During the lifting process, the connecting rod drives the sleeve frame to move. The sleeve frame moves up and down at the position where it is in contact with the outer wall of the fixed column. This increases the stability of the lifting platform when it rises or falls and prevents it from shaking during the movement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The utility model provides, for example Figure 1-4 The paper machine headbox angle adjustment mechanism shown includes a base plate 1. A first hydraulic cylinder 2 is installed at the upper end of the base plate 1. The first hydraulic cylinder 2 drives a lifting platform 11 at the upper end to move up and down. A third hydraulic cylinder 8 is installed at the right side of the upper end of the lifting platform 11. A slide groove 7 is provided at the inner side of the upper end of the lifting platform 11. A fixing rod 6 is fixed at the inner side of the slide groove 7. A movable plate 5 is installed at the inner side of the slide groove 7 through the fixing rod 6. A second hydraulic cylinder 3 is installed at the upper end of the movable plate 5. A rotating shaft 15 is provided at the inner side of both the second hydraulic cylinder 3 and the third hydraulic cylinder 8. An mounting plate 4 is fixed at the outer end face of the rotating shaft 15. Connecting rods 12 are fixed at the left and right ends of the lifting platform 11. A sleeve frame 13 is fixed at the other end of the connecting rod 12. A fixing column 10 is sleeved inside the sleeve frame 13.

[0025] The paper machine headbox is installed at the upper position using mounting plate 4 and bolts. When the paper machine headbox is raised or lowered, the lifting platform 11 is moved by the first hydraulic cylinder 2, causing the paper machine headbox to rise or fall. When adjusting the angle, the second hydraulic cylinder 3 or the third hydraulic cylinder 8 can be activated, thus raising the height of one side of the paper machine headbox. At this time, the mounting plate 4 rotates around the rotating shaft 15 as the center axis. The rotating shaft 15 rotates inside the hydraulic rod to adapt to the angle change of the paper machine headbox. When the hydraulic cylinders inside the second hydraulic cylinder 3 and the third hydraulic cylinder 8 are in the initial state, the paper machine headbox is in a horizontal state.

[0026] like Figure 1 and Figure 2 As shown, mounting plate 4 has mounting holes 14 at the four corners on its upper end. Mounting plate 4 is installed to the headbox of papermaking machine through mounting holes 14 and bolts. A lifting rod is provided inside the first hydraulic cylinder 2. The first hydraulic cylinder 2 drives the lifting platform 11 to rise and fall through hydraulic oil and the lifting rod. When the hydraulic rods inside the third hydraulic cylinder 8 and the second hydraulic cylinder 3 are in the initial state, the two mounting plates 4 are at the same height.

[0027] The hydraulic pump starts, delivering hydraulic oil from the tank to the rodless chamber of the hydraulic cylinder through pipelines. The hydraulic oil forms high pressure in the rodless chamber, pushing the piston upward and causing the hydraulic rod to extend. The hydraulic rod then pushes the headbox vertically upward via the lifting platform 11 until the set height is reached.

[0028] like Figure 2 and Figure 3 As shown, the fixed column 10 is fixed to the ground. During the lifting process, the lifting platform 11 causes the sleeve frame 13 to move along the outer wall of the fixed column 10. The height of the fixed column 10 is less than the height of the mounting plate 4. The fixed plate 9 is fixed at the upper end of the fixed column 10. The rotating shaft 15 is located inside the hydraulic rod of the third hydraulic cylinder 8 and the second hydraulic cylinder 3. The mounting plate 4 can rotate around the rotating shaft 15. The fixed rod 6 is sleeved inside the moving plate 5, and the moving plate 5 can move laterally along the fixed rod 6. The second hydraulic cylinder 3 can be adjusted in position through the moving plate 5.

[0029] During the lifting process, the lifting platform 11 moves the connecting rod 12 to drive the sleeve frame 13 to move. The sleeve frame 13 moves up and down while adhering to the outer wall of the fixed column 10. This increases the stability of the lifting platform 11 when it rises or falls and prevents it from shaking during the movement.

[0030] 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.
