Description

Technical Field

[0002] In the field of modern materials, ASA materials (acrylonitrile styrene acrylate copolymers) have been widely used in many industries such as automobile manufacturing, architectural decoration, and electronic appliances due to their unique properties, such as excellent weather resistance, good mechanical strength, and outstanding appearance. However, the thermal sensitivity of ASA materials is a characteristic that cannot be ignored during its processing. When processing ASA materials, stirring is a common and critical step. The purpose of stirring is to achieve uniform mixing of materials in order to achieve the desired physical and chemical properties.

[0003] However, due to the heat-sensitive nature of ASA materials, conventional stirring devices often fail to meet the requirements. During the stirring process, the continuous friction between the stirring parts and the ASA material will generate a large amount of heat. If this heat cannot be dissipated in time, the local temperature will rise rapidly, causing the chemical structure of the material to change, the molecular chain to break, and the physical properties of the material to deteriorate, such as reduced strength and poor toughness. In actual applications, products made of such improperly stirred ASA materials may have quality problems such as easy cracking, deformation, and fading. For example, in the field of electronics and electrical appliances, the outer casing made of such ASA materials may become fragile, reducing the protection of internal components. In the construction industry, the ASA materials used to make doors and windows may affect the sealing effect and service life due to poor performance. Utility Model Content

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-7 A stirring device for processing heat-sensitive ASA materials, comprising: a stirring box 1, used to accommodate the heat-sensitive ASA material to be stirred; a connecting rod 3, rotatably connected to the stirring box 1; a plurality of stirring members 4, and the plurality of stirring members 4 are firmly connected to the connecting rod 3; a water inlet channel 303, which is opened in the connecting rod 3, and the water inlet channel 303 is used to guide the flow path of the cooling medium; a plurality of water outlet channels 304, which are evenly opened in the connecting rod 3, and the water outlet channels 304 are used to discharge the cooling medium after heat exchange; a U-shaped water channel 401, which is opened in the stirring member 4, and the water inlet end of the U-shaped water channel 401 is connected to the water inlet channel 303, and the water outlet end is connected to the water outlet channel 304.

[0027] Through the cooperation between the above structures, the stirring member 4 and the connecting rod 3 are cooled, and the problem that when the heat-sensitive ASA material is stirred, the stirring structure will generate friction with the heat-sensitive ASA material, thereby causing the local temperature to rise rapidly, thereby affecting the material performance is solved.

[0028] The water inlet groove 301 is provided in the mixing box 1 and the connecting rod 3, and the water outlet groove 302 in the mixing box 1 is rotationally sealed and connected with the water outlet groove 302 in the connecting rod 3, and the water inlet groove 301 is communicated with the water inlet channel 303, and is used to introduce the external cooling medium into the water inlet channel 303 of the connecting rod 3; the water outlet groove 302 is provided in the mixing box 1 and the connecting rod 3, and the water outlet groove 302 in the mixing box 1 is rotationally sealed and connected with the water outlet groove 302 in the connecting rod 3, and the water outlet groove 302 is communicated with the water outlet channel 304, and is used to export the cooling medium after heat exchange; wherein the water inlet groove 301 and the water outlet groove 302 are both annular grooves.

[0029] Through the cooperation between the above structures, it can be ensured that the cooling medium stably enters the connecting rod 3 and the stirring member 4.

[0030] The water inlet 101 is opened in the mixing box 1, and the water inlet 101 is connected to the water inlet tank 301, and the water inlet 101 is used to connect to an external cooling water source; the water outlet 102 is opened in the mixing box 1, and the water outlet 102 is connected to the water outlet tank 302, and the water outlet 102 is used to discharge the used cooling medium to the outside.

[0031] Through the mutual cooperation between the above structures, a smooth connection between the external cooling water source and the internal cooling system of the stirring device is achieved, and the cooling medium is discharged in an orderly manner after use, ensuring the continuous renewal and effective circulation of the cooling medium.

[0032] The driving motor 2 is stably mounted on the mixing box 1 , and the output end of the driving motor 2 is firmly connected to the connecting rod 3 , and the driving motor 2 is used to provide rotational power for the connecting rod 3 .

[0033] It provides stable and continuous rotational power for the connecting rod 3, drives the stirring element 4 to stir efficiently, and ensures the smooth progress of the stirring process.

[0036] The water inlet groove 301 is located directly below the water outlet groove 302 .

[0037] It is possible to avoid mutual interference between the cooling media in the water inlet tank 301 and the water outlet tank 302 .

Since the water inlet groove 301 is connected to the water inlet channel 303, the cooling medium can be stably introduced into the water inlet channel 303 of the connecting rod 3; then, the driving motor 2 is started, and its output end drives the connecting rod 3 to rotate, thereby driving the multiple stirring elements 4 in the stirring box 1 to stir the heat-sensitive ASA material; during the stirring process, the stirring elements 4 and the connecting rod 3 generate heat due to friction with the material; and the cooling medium flows from the water inlet channel 303 into the U-shaped water channel 401 in the stirring element 4, filling After absorbing heat, the cooling medium that has undergone heat exchange enters the annular water outlet groove 302 from the water outlet channel 304, and is finally discharged to the outside through the water outlet 102, thereby realizing continuous renewal and effective circulation of the cooling medium. During the rotation of the connecting rod 3, since the water inlet groove 301 and the water outlet groove 302 are both annular grooves, the cooling medium can be continuously and stably in and out without being affected by the rotation of the connecting rod 3 during its rotation. The design of the annular groove ensures that the connection with the corresponding channel can be maintained at any rotation angle, so that the supply and discharge of the cooling medium are always smooth, and there will be no interruption or fluctuation caused by rotation, thereby providing a continuous and effective cooling effect for the stirring device.
