Description

Technical Field

[0001] The utility model relates to the technical field of stirrers, in particular to a composite material stirrer. Background Art

[0002] The matrix materials of composite materials are divided into two categories: metals and non-metals. Composite materials are new materials formed by people using advanced material preparation technologies to optimize and combine material components with different properties. Each material makes up for each other's weaknesses in performance, producing a synergistic effect, so that the comprehensive performance of the composite material is better than that of the original constituent materials and meets various different requirements. Before processing, composite materials need to be proportioned and mixed with different components through a mixing device.

[0003] The mixing device is usually a stirrer. A variety of raw materials with different components are added to a mixing barrel, and the various raw materials are mixed by stirring. For example, Chinese Patent No. CN216537973U discloses a composite material mixing device with a self-cleaning function. It can realize the mixing of composite materials by driving the main shaft 7 and the stirring rod 8 to rotate through the motor 3. However, in actual use, the shape of the stirring rod and the mixing effect of the fixed setting are poor. It can only stir the raw materials in the area where the height of the stirring rod is located, and the time required to achieve sufficient stirring is relatively long, reducing the production efficiency of enterprises. Summary of the Utility Model

[0004] In order to solve the technical problems existing in the above background art, the utility model provides a composite material stirrer.

[0027] Embodiment

[0028] As mentioned in the background art, a stirrer is needed to mix various raw material components during the production process of composite materials. However, when the existing stirrer is in use, the inventor found that there are many defects. On the one hand, the self - design of the stirring rod is relatively limited during the stirring process, and the stirring effect in the vertical direction is poor. Secondly, the stirring is mostly fixed stirring, so that the fluidity of the raw materials in the stirring barrel 10 is poor, and it takes a long time to stir evenly. Therefore, the inventor improved the existing stirrer and designed a new type of stirrer. The following will be described in detail with reference to the drawings.

[0029] This embodiment provides a composite material stirrer. Refer to Figure 1 , the dotted part shows the internal structure of the fixed cylinder 2. It includes a base 1, and the base 1 is placed on the bottom surface or a reference plane. The fixed cylinder 2 is installed on the base 1. The upper end of the fixed cylinder 2 is open and is arranged vertically upward. And an installation shell 3 is movably arranged at the top of the fixed cylinder 2. The movable arrangement means that the installation shell 3 can be lifted and lowered, and then drive the stirring tool to be lifted and lowered synchronously, increasing the stirring area in the vertical direction.

[0030] In this embodiment, the stirring utensils are first introduced. Among them, the installation housing 3 is horizontally arranged at the upper end of the fixed cylinder 2. At the bottom of one end of the installation housing 3, there is a stirring motor 4, and the output end of the stirring motor 4 is arranged upward. At the bottom of the other end of the installation housing 3, there is a stirring assembly 5, and the stirring motor 4 drives the stirring assembly 5 to rotate through a driving assembly 6. In order to hold the raw materials and carry out stirring, a stirring barrel 10 is also arranged on the base 1, and the stirring assembly 5 extends into the stirring barrel 10. Driven by the stirring motor 4, the driving assembly 6 can drive the stirring assembly 5 to stir the raw materials in the stirring barrel 10.

[0031] On the basis of the above structure, a connecting frame 11 is sleeved on the outer edge surface of the fixed cylinder 2, and the connecting frame 11 is connected to the stirring barrel 10 through a clamp 12. The clamp 12 can adopt the existing method of fixing a cylindrical part. Moreover, the connecting frame 11 is sleeved with the fixed cylinder 2 and fixed by a buckle, which can be disassembled. When it is necessary to place or take out the stirring barrel 10, only the clamp 12 needs to be opened to complete the subsequent operation.

[0032] Among them, the driving assembly 6 is installed in the installation housing 3, and combined with Figure 2 , the installation housing 3 is not equipped with a top cover, including a driving pulley 61 and a driven pulley 62, which are connected by a transmission belt 63. The transmission belt 63 bypasses the driving pulley 61 and the driven pulley 62. The driving pulley 61 is driven to rotate by the stirring motor 4, and then the driven pulley 62 is driven to rotate through the transmission belt 63. The driving pulley 61 is connected to the output end of the stirring motor 4, and the driven pulley 62 is connected to the stirring assembly 5. Then, the driven pulley 62 can drive the stirring assembly 5 to carry out the stirring work.

[0033] On the basis of the above structure, since the end where the stirring motor 4 is installed is heavier, the distance from the axis of the fixed cylinder 2 to the axis of the driving pulley 61 is less than the distance to the axis of the driven pulley 62, which can make the load-bearing at the bottom of the installation housing 3 more balanced and improve the stability.

[0034] As one of the main design points of this solution, combined with Figure 3, the stirring assembly 5 includes a stirring shaft 51 connected to the driven pulley 62. The stirring shaft 51 is connected to the driven pulley 62 through components such as a bearing seat and a flange. A spiral stirring blade 52 is installed on the outer edge surface of the stirring shaft 51. The spiral stirring blade 52 can improve the flow of raw materials in the vertical direction while rotating and stirring. On the basis of the above structure, a fixing plate 53 is installed at the upper end of the stirring shaft 51. The fixing plate 53 is installed at the bottom of the flange, symmetrically arranged on both sides of the stirring shaft 51. Stirring blades 54 are respectively installed on the front and rear sides of both ends of the fixing plate 53. That is, one of the two stirring blades 54 is installed on the front side of the fixing plate 53, and the other is installed on the rear side of the fixing plate 53. And the two stirring blades 54 respectively spiral downward from the front and rear sides of the spiral stirring blade 52 and are respectively connected to the bottom end of the spiral stirring blade 52. That is, the stirring blade 54 moves downward from one end of the fixing plate 53 towards the stirring shaft 51 until the lower end is fixedly connected to the bottom of the spiral stirring blade 52.

[0035] Specifically, during stirring, the driven pulley 62 drives the stirring shaft 51 to rotate, and then drives the spiral stirring blade 52 to rotate while making the principle flow in the vertical direction. At the same time, the stirring blade 54 rotates along with the fixing plate 53, and can stir the flowing raw materials in the vertical direction, increasing the stirring area.

[0036] Moreover, the length of the fixing plate 53 is not less than 3 / 5 of the inner diameter of the stirring barrel 10, which can increase the extension range of the stirring blade 54. The best effect is that the length of the fixing plate 53 is the same as the diameter of the stirring barrel 10, so that the stirring blade 54 can cover the edge position of the stirring barrel 10 horizontally.

[0037] As one of the other main design points of this solution, a lifting motor 7 is installed at the upper end of the installation housing 3, and the output end of the lifting motor 7 is connected to a lead screw 8. The lead screw 8 penetrates into the fixed cylinder 2, and a nut 9 threadedly connected to the lead screw 8 is fixed in the fixed cylinder 2. Since the stirring barrel 10 can limit the fixing plate 53, and then limit the rotation of the installation housing 3. However, in order to improve the stability of lifting, limit rods can be arranged on both sides of the lead screw 8, and the limit rods are connected to the bottom of the installation housing 3. Limiting cylinders for the penetration of limiting columns are arranged on both sides of the nut 9. When the installation housing 3 moves up and down, the limiting columns can slide up and down along the limiting cylinders. The lifting motor 7 can drive the lead screw 8 to rotate, and then can move in the vertical direction through the threaded connection with the nut 9, driving the entire installation housing 3 to move up and down, and then driving the stirring assembly 5 to move up and down in the vertical direction, so that the spiral stirring blade 52 and the stirring blade 54 can move up and down in the stirring barrel 10, realizing the stirring of raw materials at different height positions in the stirring barrel 10 and improving the stirring effect.

[0038] On the basis of the above structure, the nut 9 is fixed at a position close to the upper edge of the fixed cylinder 2, and the upper end face of the nut 9 does not exceed the upper end face of the fixed cylinder 2, preventing the length of the suspended part of the lead screw 8 from being too large when it rises, which may cause the entire installation housing 3 to shake. When the nut 9 is arranged at the top of the fixed cylinder 2, the distance between the installation housing 3 and the nut 9 can be reduced, thereby reducing the shaking of the installation housing 3 and improving stability.

[0039] Moreover, the height of the fixed cylinder 2 is 1m - 1.8m, creating a relatively high space between the installation housing 3 and the base 1, which is convenient for placing stirring barrels 10 with various height dimensions. The length of the lead screw 8 is 1 / 2 - 2 / 3 of the height of the stirring barrel 10, ensuring that the lead screw 8 can be lifted by at least half of the height of the stirring barrel 10, and then ensuring that the spiral stirring blade 52 and the stirring blade 54 can move up and down within a relatively large range in the stirring barrel 10, further increasing the stirring range.
