Abstract
Description
Technical Field
[0001] This utility model relates to the field of stone-based paper production technology, specifically to a stirring paddle for mixing stone-based paper raw materials. Background Technology
[0002] In the extrusion production of stone paper, powder mixing is a crucial step in ensuring uniform mixing of raw materials and improving production efficiency. The main components of stone paper are calcium carbonate and polyethylene, which need to be thoroughly mixed before extrusion to ensure the quality of the final product. However, current mixing technologies, especially in the field of powder mixing, still have some significant shortcomings that affect mixing effectiveness and production efficiency.
[0003] Most existing mixing equipment uses welded powder mixing paddles. This design is typically suitable for a limited range of mixing chambers and has relatively fixed dimensions and shapes. These devices are usually designed based on traditional, single-method mixing, and their paddle structure and dimensions lack flexibility, thus limiting their operation to specific conditions. This fixed paddle shape typically restricts the equipment's applicability and cannot effectively address the mixing needs of different materials and production conditions. For example, welded paddles are only suitable for mixing chambers with a certain diameter range, making it difficult to flexibly adjust to different production requirements, resulting in uncontrollable mixing effects during production. In practical applications, the viscosity, particle size, and flowability of materials constantly change, and existing fixed paddles cannot dynamically adjust to these changes, leading to uneven material mixing or decreased mixing efficiency.
[0004] Furthermore, existing mixing equipment often employs single-shaft or dual-shaft rotation. While it can accomplish basic material mixing tasks, its mixing mode is too simplistic and lacks effective adjustment in multi-dimensional space. This inflexible design makes it difficult to precisely control the mixing effect under different materials or production conditions. Especially when dealing with high-viscosity materials or special process requirements, traditional mixing equipment often exhibits poor adaptability and mixing performance. Due to the limited adjustment range of the equipment, uneven mixing or dead zones may occur in certain areas, affecting the final uniformity of material mixing and extrusion quality.
[0005] In summary, while existing welded powder mixing paddles can meet general production needs, their fixed structure and single operating mode result in a lack of flexibility in production methods and uncontrollable mixing effects. In view of the above problems, a mixing paddle for mixing stone-based paper raw materials is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a stirring paddle for mixing stone-based paper raw materials, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a stirring paddle for mixing stone-based paper raw materials, comprising a transmission mechanism, a connecting rod mounted at the bottom end of the transmission mechanism, and a plurality of torsion bars one and two mounted at the top and bottom of the connecting rod, respectively.

[0012] Preferably, a transmission component is welded to the top of the mating flange.
[0013] Preferably, the transmission component is a pulley or a sprocket.
[0014] Preferably, the included angle between the axis of the inclined screw hole and the inclined hole is 90°, and the axis of the inclined screw hole and the inclined hole are symmetrically arranged with the axis of the connector as the center line.
[0015] Preferably, the positioning rod one and positioning rod two are respectively twisted into torsion rod one and torsion rod two on both sides, and the outer sides of the torsion rod one and torsion rod two are respectively integrally formed with connector one and connector two. The outer sides of connector one and connector two are provided with screw holes. The stirring rod includes a spiral-shaped spiral rod, and the two sides of the spiral rod are respectively integrally formed with connector three. The two connector three are respectively assembled and fixed to connector one and connector two by bolts.
[0016] Preferably, the outer side of the spiral rod is provided with a cutting edge.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a transmission mechanism and a connecting rod, torsion bar one, torsion bar two, and stirring rod at the bottom for rotating and stirring.

Compared with the existing welded stirring paddle that requires separate design according to the material, it has higher flexibility and adaptability. Attached Figure Description

Detailed Implementation
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figure 1-9 This utility model provides a technical solution: a stirring paddle for mixing stone-based paper raw materials, including a transmission mechanism 1, a connecting rod 2 is assembled at the bottom end of the transmission mechanism 1, and a plurality of torsion bars 3 and torsion bars 4 are respectively assembled at the top and bottom of the connecting rod 2. An arc-shaped stirring rod 5 is assembled on the outer side of the torsion bars 3 and torsion bars 4. The torsion bars 3 and torsion bars 4 are fixed to the connecting rod 2 by bolts, and the distance between the center of the torsion bars 3 and torsion bars 4 and the center of the connecting rod 2 can be adjusted.
[0033] This utility model is equipped with a transmission mechanism 1 and a connecting rod 2, a torsion bar 3, a torsion bar 4, and an agitator 5 at the bottom for rotating and stirring. In use, the rotation radius can be adjusted by removing and installing bolts and adjusting the relative positions of positioning rod 31 and positioning rod 41 with the connecting rod 2, according to the size of the mixing chamber with different mixing tonnage. It can support mixing chambers of different diameters and can be adjusted according to different mixing volumes, making it more adaptable. It effectively solves the problem that the existing welded powder mixing paddles can only be used for mixing chambers of one shape and within a certain diameter range, resulting in inflexible production methods and uncontrollable mixing effects.
[0034] Specifically, the middle parts of torsion bar 3 and torsion bar 4 are respectively provided with positioning rod 31 and positioning rod 41. The outer sides of positioning rod 31 and positioning rod 41 are provided with screw holes with a fixed spacing. The number of screw holes is at least two and they are set vertically. The screw holes are fixed to the connecting rod 2 by bolts.
[0035] like Figure 8 and Figure 9 As shown, Figure 9 The dotted line in the diagram represents the outermost rotation path of the entire structure of this application when adjusted to the maximum position. By adjusting the positions of torsion bar 3 and torsion bar 4 relative to the connecting rod 2, it is possible to achieve agitation and rotation at different positions on the inner and outer sides, thus enabling a larger range and more agitation positions, making the mixing process more uniform.
[0036] Furthermore, the greatest advantage of this application, besides being easy to adjust to accommodate mixing chambers of various sizes, is that it can even accommodate different shapes and mixing effects in different directions, such as horizontal or vertical mixing.
[0037] Meanwhile, this application, through the separately set torsion bar 3, torsion bar 4 and stirring bar 5, can realize the unified processing and manufacturing of parts of the same model, and can also be assembled more flexibly during use. Compared with the welding type of the existing technology and the stirring paddle that needs to be designed separately according to the material, it has higher flexibility and adaptability.
[0038] Specifically, the connecting rod 2 includes a transmission rod 21, with evenly distributed insertion holes 22. Positioning rod 1 31 and positioning rod 2 41 can be assembled and fixed with any of the insertion holes 22. The insertion holes 22 can be set in the same direction with equal or unequal spacing, as shown in the figure. The insertion hole 22 at the bottom of the transmission rod 21 is an open opening. When used with a wider torsion rod 2 4, it can assist in the use of the bottom positioning structure of the torsion rod 2 4.
[0039] Specifically, a sleeve joint 23 is fixedly mounted on the top of the transmission rod 21, and the transmission mechanism 1 includes a connecting member 11. A square shaft 12 is welded to the bottom of the connecting member 11. The square shaft 12 is combined and fixed with the sleeve joint 23. A square shaft structure is also mounted on the top of the connecting member 11. A square hole is opened at the center of the fixed flange 16, which can be assembled with the fixed flange 16 to assist in the transmission of axial rotation during use.
[0040] The arc-shaped rod 13 has a quarter-circle arc projection shape in both the main view and the side view. This arc structure has two functions. One function is to raise the power transmission position upward, provide more bearing installation positions, improve the smoothness of rotation, and provide a larger torque to ensure better rotation efficiency. The other function is to use the arc structure in the rotation direction to counteract the reaction force in the rotation direction. By coinciding or being close to the direction of torque, the transmission effect of power torque is improved. Compared with the inclined straight-line welded rod structure, it has a better bending resistance.
[0041] Specifically, several sets of arc-shaped rods 13 are welded to the outer side of the connector 11. An assembly ring 14 is welded to the top of the arc-shaped rod 13. An oblique screw hole 15 is opened on the top surface of the assembly ring 14. An assembly ring 17 is mated to the top of the assembly ring 14. A fixing flange 16 is welded to the inner side of the assembly ring 17. A mating flange 19 is installed on the top of the fixing flange 16. An oblique hole 18 is opened on the top of the assembly ring 17. A bolt is sleeved inside the oblique hole 18 and screwed into the oblique screw hole 15. The purpose of setting the oblique hole 18 and the oblique screw hole 15 is the same as the function of the arc-shaped rod 13. Its main purpose is to increase the rotational torque while helping to counteract the lateral bending force, improve the bending resistance, and reduce the load pressure of the weld point.
[0042] Specifically, a transmission component 110 is welded to the top of the mating flange 19.
[0043] Specifically, the transmission component 110 is a pulley or sprocket. The use of the docking flange 19 and the fixing flange 16 facilitates the replacement of different types of transmission components 110 to suit more application scenarios.
[0044] Specifically, the included angle between the axis of the inclined screw hole 15 and the inclined hole 18 is 90°, and the axis of the inclined screw hole 15 and the inclined hole 18 are symmetrically arranged with the axis of the connector 11 as the center line.
[0045] During installation, the overall structure of this application is rotated between the external mounting bearing of the connector 11 and the top cover structure of the mixing chamber. A tapered groove is evenly provided at the bottom of the positioning rod 41. The center of the tapered groove corresponds to the axis of the vertically arranged mounting holes of the positioning rod 41. In other words, the axis of the tapered groove corresponds to the center of the adjusted installation position, ensuring that after adjusting the position of an adjacent mounting hole, the axis of the tapered groove can coincide with the center of the axis of the connecting rod 2. In use, it is mainly used to assist in determining the axis position of the connecting rod 2.
[0046] In addition to vertical installation, this application can also be used to horizontally mount the transmission rod 21, which is extended and has a non-open bottom, with bearings on both sides, to both ends of the mixing chamber for horizontal mixing effect.
[0047] Specifically, torsion bars 32 and 42 are twisted and formed on both sides of positioning rod 31 and positioning rod 41, respectively. Connector 33 and connector 43 are integrally formed on the outer sides of torsion bars 32 and torsion bars 42, respectively. Threaded holes are opened on the outer sides of connector 33 and connector 43. Stirring rod 5 includes a spiral rod 51. Connector 33 is integrally formed on both sides of spiral rod 51. The two connector 33 are respectively assembled and fixed to connector 33 and connector 43 by bolts.
[0048] Specifically, the outer side of the spiral rod 51 is provided with a cutting edge 52.
[0049] The stirring rod 5, the torsion rod 1 3 and the torsion rod 3 can all be made by integral molding and torsion bending. Multiple sets can be made at once, which makes them easy to assemble during use and easy to replace when there is local wear or changes in the position of the shaft.
[0050] Through multiple sockets 22 and connecting rods 2 of different lengths, several sets of torsion bars 3 can be added to work with stirring rods 5. For example, in the figure, a torsion bar 3 is installed inside each of the two empty sockets 22. By using stirring rods 5 with smaller vertical spacing, the bottom of two adjacent torsion bars 3 can be combined and assembled to achieve the effect of more sets of stirring rods 5 rotating and stirring synchronously.
[0051] Besides the shape of this utility model, the stirring rod 5 can also be a straight rod, or a wider sheet structure, or other shapes. During manufacturing, it is only necessary to ensure that the connecting head 3 53 has uniform dimensions.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
