Description

Technical Field

[0001] The utility model relates to the field of material preparation equipment, in particular to a highly stable roller. Background Art

[0002] The development of one-dimensional / two-dimensional membrane materials has been rapid, bringing new opportunities for the performance breakthrough and function expansion of traditional functional thin films. Common methods for preparing thin films include: suction filtration method, spin coating method, electrospinning method, and spin coating method, etc.

[0003] As a widely used thin film preparation technology, the working principle of the spin coating method is mainly to drop a solution or dispersion on a rotating substrate, and use centrifugal force to evenly distribute the liquid, and then form a uniform and continuous thin film through the evaporation of the liquid. This method is widely used in the preparation process of various thin films because of its simple, fast and low-cost preparation process.

[0004] However, when using a roller as a substrate for spin coating, the roller often shakes and deviates during high-speed rotation, resulting in poor stability of the roller, which in turn affects the uniformity and quality of the thin film. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a highly stable roller, which is used to solve the technical problem that the stability of the roller is poor during high-speed rotation in the prior art, resulting in uneven distribution of the coating on the surface of the roller, and thus affecting the uniformity and quality of the thin film.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A highly stable roller includes a roller equipped with a first limiting mechanism and a second limiting mechanism, and the first limiting mechanism and the second limiting mechanism are installed on the edge or non-edge of the roller.

[0008] Preferably, the second limiting mechanism further includes: a rotor, sleeved on the roller and fixedly connected with the annular guide rail; a plurality of rotor poles, all installed on the outer surface of the rotor; a mounting frame, installed on the fixed frame; a plurality of stator seats, all installed on the inner wall of the mounting frame, and each stator seat is provided with a plurality of stator pole groups.

[0009] Preferably, a bottom plate is arranged below the roller, and the fixed frames in the first limiting mechanism and the second limiting mechanism are both fixedly connected with the bottom plate.

[0010] In summary, due to the adoption of the above technical solutions, the beneficial effects of the utility model are:

[0011] 1. In the present utility model, the first limiting mechanism and the second limiting mechanism are provided with a fixing frame, a limiting guide, an annular guide rail and a chute. The limiting guide limits and guides the annular guide rail without affecting its rotation, preventing the annular guide rail from shifting to one side during rotation. After the annular guide rail is fixedly connected to the drum, when the drum rotates, the limiting guide and the annular guide rail can prevent the drum from shifting to one side, improving the stability of the drum during rotation.

[0012] 2. In the present utility model, the driving mechanism is provided with a mounting frame, a first motor and a shaft rod. When the first motor operates, it drives the shaft rod to rotate, and then drives the drum to rotate.

[0013] 3. In the present utility model, the second limiting mechanism is provided with a toothed ring, a mounting plate, a second motor and a gear. By simultaneously starting multiple second motors, the multiple gears are driven to rotate, and then the toothed ring is driven to rotate through meshing. When the toothed ring rotates, it drives the annular guide rail to rotate, and then drives the drum to rotate.

[0014] 4. In the present utility model, the second limiting mechanism is provided with a rotor, rotor poles, a mounting frame, a stator base and a stator pole group. By supplying power to the stator pole group and under the influence of the rotor poles, the rotor rotates, which then drives the annular guide rail to rotate, and further drives the drum to rotate.

[0026] The specific embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0027] Embodiment 1

[0028] As Figures 1 - 3 shown, a highly stable drum includes a drum 100, a first limiting mechanism 210 and a second limiting mechanism 220.

[0029] The drum 100 is cylindrical, one side of the drum 100 is open, and a bottom plate 101 is provided below the drum 100.

[0030] Both the first limiting mechanism 210 and the second limiting mechanism 220 are used to prevent the drum 100 from shifting to one side, so as to improve the stability of the drum 100 during rotation.

[0031] Both the first limiting mechanism 210 and the second limiting mechanism 220 include a fixing bracket 201, a plurality of limiting guides 202, an annular guide rail 203 and two chutes 204. The fixing bracket 201 is arranged in a square shape with an opening, and the fixing bracket 201 is installed on the bottom plate 101. A plurality of limiting guides 202 are installed on the inner wall of the fixing bracket 201. The annular guide rail 203 is used for fixedly connecting with the drum 100, and the annular guide rail 203 is composed of a plurality of arc-shaped guide rails connected. Two chutes 204 are respectively opened on both side surfaces of the annular guide rail 203, and the chutes 204 are matched with the limiting guides 202.

[0032] The position-limiting and guiding member 202 includes a mounting base 2021, a plurality of connecting rods 2022, and a plurality of rollers 2023. The mounting base 2021 is mounted on the inner wall of the fixing frame 201; the plurality of connecting rods 2022 are mounted on the mounting base 2021; the plurality of rollers 2023 are respectively rotatably connected to the plurality of connecting rods 2022, and the plurality of rollers 2023 are respectively located in two sliding grooves 204 and are in rolling connection with the sliding grooves 204.

[0033] Specifically, through the position-limiting and guiding member 202, the position-limiting and guiding of the annular guide rail 203 are achieved without affecting the rotation of the annular guide rail 203, thereby preventing the annular guide rail 203 from shifting to one side during rotation. When the annular guide rail 203 is fixedly connected to the roller 100, during the rotation of the roller 100, the position-limiting and guiding member 202 and the annular guide rail 203 can prevent the roller 100 from shifting to one side.

[0034] As Figure 1 shown, the first position-limiting mechanism 210 and the second position-limiting mechanism 220 are mounted on the edge or non-edge of the roller 100.

[0035] As Figure 3 shown, a driving mechanism 110 is provided on one side of the roller 100. The driving mechanism 110 includes a mounting frame 111, a first motor 112, and a shaft rod 113.

[0036] Specifically, when the first motor 112 operates, it will drive the shaft rod 113 to rotate, and then drive the roller 100 to rotate.

[0037] Working principle: During specific use, by mounting the fixing frame 201 in the first position-limiting mechanism 210 and the second position-limiting mechanism 220 on the top surface of the bottom plate 101, and then fixedly mounting the annular guide rail 203 in the first position-limiting mechanism 210 and the second position-limiting mechanism 220 on the roller 100, the roller 100 is located within a plurality of fixing frames 201.

[0038] When the first motor 112 is started, it will drive the shaft rod 113 to rotate, and then drive the roller 100 and the annular guide rail 203 to rotate. Due to the provision of the position-limiting and guiding member 202, the position-limiting and guiding of the annular guide rail 203 are achieved without affecting the rotation of the annular guide rail 203, preventing the annular guide rail 203 from shifting to one side during rotation, and further preventing the roller 100 from shifting to one side, improving the stability of the roller 100 during rotation.
