Description

Technical Field

[0001] The utility model belongs to the technical field of stirring equipment, and particularly relates to a rotary stirring device with high-efficiency vacuum pumping. Background Art

[0002] In industrial production and daily life, latex or rubber chemical products are common. During the processing of the glue liquid raw materials used to produce such products, air bubbles are likely to form inside the glue liquid. Due to the high viscosity of the glue liquid, it is difficult for the air bubbles to escape from the glue liquid by themselves. To ensure the quality and appearance of the products, the glue liquid raw materials need to be degassed during the processing of such products.

[0003] As a commonly used stirring and mixing device for basic materials, the degassing mixer is the main tool for realizing the degassing treatment of glue liquid raw materials. It is mainly applied to the mixing and stirring fields of materials for high-end, sophisticated products such as LED, LCD, medical devices, electronic components, nano powder materials, fine chemical materials, printed electronic materials, electronic packaging materials, and new energy materials, and can realize the stirring of liquid-solid, liquid-liquid, and solid-solid substances.

[0004] However, for such stirring and degassing equipment, as Figure 4 shown, the entire movement structure of the rotary stirring body and its rotation around the sun and self-rotation are in a sealed vacuum chamber. The air in the sealed chamber is pumped out by a vacuum pump to form a vacuum negative pressure environment, thereby assisting in removing air bubbles during the stirring and dispersion process of the materials. However, for such stirring and degassing equipment with this structure, since the entire transmission structure of the rotation around the sun and self-rotation is in a vacuum environment, when pumping vacuum, the entire machine cover needs to be pumped out to form a vacuum cavity inside the machine cover. Due to the generally large space of the machine cover, this vacuum pumping method is generally slow and costly, resulting in an extended operation time of the entire equipment and a reduction in the production efficiency of the equipment. Moreover, the larger the volume of the vacuum sealed space, the more difficult it is to ensure its airtightness, and it is very likely that the complete vacuum effect cannot be achieved. Content of the Utility Model

[0005] To solve the above problems, the purpose of the utility model is to provide a rotary stirring device with high-efficiency vacuum pumping, which can shorten the vacuum pumping time of the device, reduce costs, and improve production efficiency.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The utility model provides a rotary stirring device with high-efficiency vacuum pumping, including:

[0008] A machine platform;

[0009] A driving mechanism, fixed to the machine platform;

[0010] A rotary stirring body, connected to the driving mechanism;

[0011] Air pipe assembly;

[0012] A vacuum pumping mechanism is connected to the rotary stirring body through the air pipe assembly to achieve vacuum pumping of the rotary stirring body.

[0013] In this application, the vacuum pumping mechanism is directly connected to the rotary stirring body through the air pipe assembly, and the rotary stirring body can be directly vacuum pumped. Compared with the existing vacuum chamber for defoaming and stirring, the space for vacuum pumping can be greatly reduced, the time for the device to vacuum pump can be shortened, the cost can be reduced, and the production efficiency can be improved.

[0014] Further, the driving mechanism includes a driving motor and a transmission assembly. The driving motor is fixed to the machine platform, the rotary stirring body is connected to the driving motor through the transmission assembly, the air pipe assembly includes a first air pipe, a shunt joint, a second air pipe, and an air pipe joint.

One end of the first air pipe is connected to the shunt joint, and the other end is connected to the rotary stirring body one-to-one through the air pipe joint. In this application, by providing an air vent hole in the driving motor to cooperate with the air pipe assembly to vacuum pump the rotary stirring body, the length of the air pipe can be reduced, and the air pipe can be fixed by the driving motor to avoid the swing of the air pipe affecting the stability of the device.

[0015] Further, the transmission assembly includes a middle shaft gear, a transmission gear set, and a connecting rod.

The connecting rod is connected to the output shaft of the driving motor and the transmission gear shaft. In this application, the middle shaft gear is fixed on the machine platform and sleeved on the output shaft of the motor. When the driving motor works, it will drive the transmission gear set to rotate around the middle shaft gear through the connecting rod to realize the revolution of the rotary stirring body; and because the middle shaft gear is fixed relative to the machine platform, when the transmission gear set rotates around the middle shaft gear, the transmission gear meshing with the middle shaft gear will rotate self, and then drive the stirring chamber gear to rotate self through the other transmission gear, thereby realizing the self-rotation of the rotary stirring body, and realizing the integration of self-rotation and revolution of the rotary stirring body.

[0016] Further, an inner shaft sleeve is arranged outside the output shaft of the driving motor. The bottom of the middle shaft gear is fixedly connected with an outer shaft sleeve and a shaft sleeve base in sequence. The shaft sleeve base is fixedly connected with the machine table. The inner shaft sleeve is rotationally connected with the middle shaft gear, the outer shaft sleeve and the shaft sleeve base. The inner shaft sleeve is sleeved outside the output shaft of the driving motor and is fixedly connected with the output shaft of the driving motor. The top of the inner shaft sleeve is fixedly connected with the connecting rod. In the present application, during the working process of the driving motor, the force-bearing area of the motor output shaft can be increased through the long support of the inner shaft sleeve, avoiding excessive force on the top of the motor output shaft. And the structural stability of the bottom of the motor output shaft is strengthened through the outer shaft sleeve and the outer shaft sleeve base, avoiding the swing of the motor output shaft and improving the structural stability of the motor output shaft.

[0017] Further, a revolution support plate is also connected to the bottom of the rotary stirring body. A positioning hole is arranged at the bottom of the revolution support plate. The positioning hole is arranged inside the outer shaft sleeve, and a bearing is also arranged between the support ring and the outer shaft sleeve.

The stirring rotating shaft is connected to the bottom of the vacuum barrel. The stirring rotating shaft passes through the stirring chamber gear and the rotary body bearing, and the stirring rotating shaft is fixedly connected with the stirring chamber gear. The rotary body bearing is arranged below the stirring chamber gear. The bearing seat wraps outside the rotary body bearing, and the bearing seat is fixedly connected with the revolution support plate. In the present application, setting the stirring chamber gear of the rotary body above the bearing and directly meshing with the transmission gear set can facilitate observing gear abnormalities, simplify the structure, and facilitate installation, maintenance, and replacement.

[0020] Further, a glue barrel is also arranged inside the vacuum barrel. The air pipe joint is communicated with the glue barrel.

[0021] Further, the air pipe joint is a rotating joint and can rotate 360 degrees, ensuring that the vacuuming is not affected when the vacuum barrel rotates.

[0022] Further, the vacuuming mechanism includes a vacuum pump and a filter. The vacuum pump is connected to the first air pipe through the filter.

[0023] Further, two groups of rotary stirring bodies are arranged. The two groups of rotary stirring bodies are symmetrically arranged on both sides of the driving motor. The ventilation hole penetrates through the output shaft of the driving motor, making the output shaft of the motor and the vacuum shaft integrated, which can simplify the structure.
