Description

Technical Field

[0001] The present invention relates to a method for manufacturing composite artificial stone without vacuum extraction and its processing device, belonging to the field of artificial stone. Background Art

[0002] For the existing composite artificial stone, whether it is made from blocks or plates, vacuum extraction and pressing are required to eliminate the pores inside the blocks and plates. Vibration pressing mainly improves the density of the artificial stone and the cohesion between materials, so as to meet the relevant standards of building materials. First, the proportioned and weighed materials are stirred evenly and poured into the mold. The stirred materials in the mold are leveled manually or mechanically and are prone to color bleeding. Then, vacuum extraction is carried out. After the vacuum degree reaches the requirement, generally, the vacuum extraction takes about 10 - 15 minutes. Then, vibration extrusion is carried out, and the vibration pressing takes about 3 - 5 minutes. After pressing and densifying, the production of the plate is completed. After 24 hours, demolding and curing are carried out. After curing for 14 days, grinding and polishing are carried out to complete the finished plate. Therefore, the time spent on vacuum extraction greatly reduces the production efficiency. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a method for manufacturing composite artificial stone without vacuum extraction and its processing device to solve the problems.

[0004] To achieve the above purpose, the present invention is realized through the following technical solutions: A method for manufacturing composite artificial stone without vacuum extraction includes the following steps;

[0005] Step 1: Select a metal plate with a length equal to the length of the mold and a width equal to the width of the mold. The metal plate is rolled into a circle to form a hollow cylindrical container; and there is a snap lock for fixing at the joint of the hollow cylinder.

[0006] Step 2: Stir the ingredients of the composite artificial stone until there are no particles and fine powders, and then pour them into the container.

[0007] Step 3: Place the container on a rotating platform and rotate the container.

[0008] Step 4: Insert a scraping rod into the center of the container. Keep the container rotating and make the scraping rod slowly approach the inner wall of the container. Use rotational extrusion to make the stacked materials gradually become thinner and higher until they are extruded to the rated height or thickness.

[0009] Step 5: Continue to rotate the container and then stop rotating.

[0010] Step 6: Take out the container, then lay it flat, place it in the mold and remove the iron plate, so that the stirred materials are evenly spread in the mold.

[0011] Step 7: The mold is conveyed to a vibrator through a conveyor belt for vibration, and then the mold is sent into a press for vacuum pressing.

[0012] Step 8: After standing still, demolding and then grinding and polishing are carried out to produce finished plates.

[0015] Beneficial effects

[0016] First, the present invention saves the vacuum pumping time. Second, it saves the time for manual or mechanical spreading of the slurry and the problem of uneven spreading and uneven density caused by uneven spreading. Third, by using different angles and different outward pushing speeds of the scraping rod, different continuous patterns can be formed, and the patterns are very natural without color bleeding phenomenon. Fourth, only through the outward pushing work of the scraping rod, the action is single, so the manufacturing speed is fast. Description of the drawings
