Description

Technical Field

[0001] This utility model relates to the field of polymer materials technology, specifically to a melt blending tank for polymer material processing. Background Technology

[0002] The production of plastic products typically involves the melt blending of composite antistatic agents with polymer materials. Polymer materials (such as plastics and rubber) usually have high surface resistivity, making them prone to static electricity accumulation due to friction or separation, leading to problems such as dust attraction, electric shock, and spark discharge. By melt blending composite antistatic agents with polymer materials, a conductive layer or network can be formed inside or on the surface of the material, reducing surface resistivity and allowing static charge to dissipate quickly, thereby eliminating the hazards of static electricity. Successful mixing of composite antistatic agents with polymer materials produces polymer products with antistatic properties, applicable to fields such as plastic packaging, static elimination materials, and semiconductors.

[0003] When mixing composite antistatic agents with polymer materials, it is necessary to carry out the process at a specific temperature, which is generally done using a melting tank. This is because the melting tank combines temperature regulation and stirring. When mixing liquid composite antistatic agents with solid polymer materials, in addition to requiring uniform mixing, the amount of composite antistatic agent must be strictly controlled. The amount of antistatic agent added is usually 0.3%-3.0%, and the specific amount needs to be adjusted according to the performance requirements of the material and environmental conditions. Too much amount may lead to a decrease in material performance (such as reduced strength), while too little amount will not achieve the desired antistatic effect. Furthermore, due to the low melting point of the antistatic agent, it may be in a liquid or high-viscosity liquid state at room temperature. When the solution is added, some of it may adhere to the metering cylinder wall, leading to inaccurate metering results for the next solution. Therefore, we propose a melt blending tank for polymer material processing. Utility Model Content

[0004] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a melt blending tank for processing polymer materials, comprising,

[0006] The melting tank is equipped with a stirring mechanism on its lid;

[0007] The lid of the melting tank is equipped with a liquid inlet, which is connected to a measuring cylinder. The measuring cylinder is equipped with a liquid addition pipe and a measuring scale.

[0008] A scraping component is attached to the inner wall of the measuring cylinder;

[0009] A lifting assembly is installed at the top of the measuring cylinder.

[0010] As a preferred embodiment of the melt blending tank for processing polymer materials according to this utility model, the lifting assembly includes an electric telescopic rod, which is disposed on the top of the metering cylinder, and the bottom power end of the electric telescopic rod extends through the top of the metering cylinder to the inner cavity of the metering cylinder.

[0012] As a preferred embodiment of the melt blending tank for processing polymer materials according to this utility model, the piston plate has a sealing ring connected to its outer wall, and the liquid inlet has a sealing groove that matches the sealing ring.

[0013] As a preferred embodiment of the melt blending tank for processing polymer materials according to this utility model, the top of the lid of the melt tank is connected to a feeding pipe, and the tank body of the melt tank is connected to an electrical box and a control switch, with the electrical box electrically connected to the electrical components on the melt tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The added composite antistatic agent is located above the piston plate. When the liquid level reaches the required metering scale, the electric telescopic rod moves downward, causing the piston plate to detach from the metering cylinder and extend from the inlet into the melting tank, allowing the composite antistatic agent to be discharged into the melting tank. By continuing to move downward, the top plate moves downward under the drive of the connecting rod, causing the scraper to scrape the inner wall of the metering cylinder, thus pushing some of the composite antistatic agent adhering to the inner wall of the metering cylinder into the preparation tank to ensure the accuracy of the metering results.

[0028] This invention proposes a melt blending tank for processing polymer materials.

The lid of the melt tank 1 is equipped with a stirring mechanism 2 for stirring and mixing various liquids.

[0031] The melting tank 1 is provided with a liquid inlet 3, and a metering cylinder 4 is connected to the liquid inlet 3. The metering cylinder 4 is provided with a liquid addition pipe 5 and a metering scale 6. The liquid addition pipe 5 is used to add the composite antistatic agent into the metering cylinder 4 for metering. It should be noted that the top of the liquid addition pipe 5 is connected to a pipe cap.

[0032] A scraping component is attached to the inner wall of the measuring cylinder 4;

[0033] A lifting assembly is installed on the top of the measuring cylinder 4.

[0034] The lifting assembly includes an electric telescopic rod 12, an electrically driven linear actuator that can convert rotational motion into linear motion to achieve telescopic function.

The control switch 15 is a mature existing technology and will not be described in detail. The electrical box 14 is electrically connected to the electrical components on the melting tank 1. The bottom of the melting tank 1 is connected to a discharge pipe 16 through a valve. The bottom four corners of the melting tank 1 are all connected to supports 17.

[0037] Example 2

[0038] Reference Figure 2 A sealing ring 11 is connected to the outer wall of the piston plate 7, and a sealing groove matching the sealing ring 11 is opened on the liquid inlet 3.
