Description

Technical Field

[0001] The utility model relates to the technical field of quartz stone production, in particular to a raw material mixing device. Background Art

[0002] The main raw materials of quartz stone are quartz sand, resin, pigment and glass fiber. These raw materials need to be screened and proportioned to ensure that the products produced meet the quality requirements. The raw materials are mixed by mixing equipment to facilitate the production of quartz stone. Quartz stone products have the characteristics of high hardness, wear resistance, acid and alkali resistance, corrosion resistance, and easy cleaning. They are widely used in building decoration, home decoration, kitchen and bathroom appliances, chemical laboratories and other fields. Common quartz stone products include quartz stone countertops, washbasins, kitchen cutting boards, quartz stone floors, wall tiles, etc.

[0003] According to a publicly disclosed mixing device for quartz stone production (publication number: CN210613545U), in the above application, through the cooperation between the first motor, the connecting shaft and the mixing drum, and then through the cooperation between the second motor, the mixing shaft and the mixing blades, the mixing device has two mixing processes in opposite directions, thereby improving the mixing efficiency.

[0004] However, in actual use, the above equipment uses a stirring shaft and stirring blades to stir and mix the raw materials in two directions. However, the raw materials will accumulate at the bottom of the mixing barrel due to gravity, resulting in incomplete mixing. At the same time, since the raw materials contain pigments, the lack of a cleaning function in the mixing barrel will lead to the risk of poor mixing effect due to the subsequent addition of pigments of different colors, thereby reducing the mixing effect. In view of this, we propose a raw material mixing device. Utility Model Content

[0015] Compared with the prior art, the utility model provides a raw material mixing device, which has the following beneficial effects:

[0016] 1.

The turntable follows the rotation through the transmission of the conveyor belt, so that the transmission wheel drives the auxiliary shaft to rotate, and the auxiliary shaft drives the stirring rod and the stirring shaft to rotate in a staggered state to mix the raw materials at the bottom of the mixing barrel. After the raw materials are mixed, the water pump introduces external water to the inside of the rotating shaft through the discharge port, and then disperses the water from the drainage hole to the inside of the mixing barrel for cleaning through the rotation of the rotating shaft, so as to prevent the raw materials from accumulating at the bottom of the mixing barrel to cause incomplete mixing, and avoid the risk of color difference after the raw materials are mixed due to the subsequent addition of pigments of different colors caused by the difficulty in cleaning the mixing barrel, thereby improving the effect of raw material mixing.

[0017] 2. The raw material mixing equipment is provided with an avoidance groove so that the stirring shaft squeezes the raw materials to impact the auxiliary shaft during the stirring process of the raw materials. The rounded corner setting prevents the raw materials from accumulating inside the avoidance groove, and enables the raw materials to fall through the transition of the rounded corners for discharge, thereby improving the stability of raw material mixing.
