Description

Technical Field

[0001] The present invention relates to the technical field of quartz stone processing, and specifically relates to a vacuum kneading and forming machine for artificial quartz stone plates. Background Technique

[0002] Quartz stone is a new type of stone that is usually said to be artificially synthesized from more than 90% quartz crystals plus resin and other trace elements. It is a large-sized plate pressed under certain physical and chemical conditions by a special machine. Its main material is quartz, which is a mineral that easily turns into a liquid state when heated or under pressure. It is also a quite common rock-forming mineral and exists in all three major types of rocks. When making artificial quartz stone plates, it is necessary to vacuum knead and form the artificial quartz stone plates. There are forming machines on the market that specifically make artificial quartz stone plates.

[0003] However, when the existing vacuum kneading and forming machine for artificial quartz stone plates is in use, there are often problems of low efficiency. First, it does not have the function of uniform kneading, resulting in the rapid discharge of the air pressure generated by the quartz stone plate itself, making the kneading and forming of the quartz stone plate uneven, and it takes a long time to knead and form it. Second, it does not have the function of rapid unloading. The material is in close contact with the surface of the forming machine body after forming, and it is not convenient for manual removal. Third, the sealing performance cannot be guaranteed, and leakage is likely to occur during the forming process, destroying the vacuum environment, which will also lead to a reduction in the forming efficiency and is not conducive to use.

[0004] Combining the above problems, we will find that when the existing vacuum kneading and forming machine for artificial quartz stone plates on the market is in use, it is very difficult to avoid the above-mentioned problems at the same time. And even if it can be solved, it needs to be solved with the cooperation of external tools, thus unable to achieve the desired effect.
