AI Technical Summary
In existing pulp molding production equipment, foam on the surface of the pulp liquid is prone to adhere during the formation of wet preforms, resulting in a decline in the appearance quality of the finished product.
Before the lower mold rises and leaves the slurry, the foam on the surface of the slurry is scraped and blown away by the cooperation of the scraper and the air blowing structure, reducing the risk of foam adhering to the wet mold.
It improves the appearance quality of the finished product, reduces the adhesion of foam on the wet blank, and enhances the aesthetics of the product.

Abstract
Claims
1. A forming apparatus, characterised in that, include: Pulp pool; The lower mold is placed inside the slurry tank; The upper mold can be closed with the lower mold to form a wet blank; The defoaming mechanism includes a moving driver, a scraper, and an air blowing structure. The scraper and the air blowing structure are connected. The moving driver drives the scraper and the air blowing structure to move along a first direction. One end of the scraper is located inside the slurry tank. The scraper is used to scrape away foam on the surface of the slurry in the slurry tank. The air outlet of the air blowing structure is inclined and faces into the slurry tank. The air blowing structure is used to blow away foam on the surface of the slurry in the slurry tank.
2. The molding apparatus of claim 1, wherein It also includes a connecting frame, the mobile driver drives the upper mold, the connecting frame connects the upper mold and the air blowing structure, and the mobile driver is used to drive the upper mold to move along a first direction so that the upper mold moves above the slurry pool or above the wet preform support module.
3. The molding apparatus of claim 2, wherein The connecting frame includes at least two connecting sections, which are telescopically configurable, wherein the two connecting sections are respectively connected to the upper mold and the air blowing structure.
4. The molding apparatus of claim 1, wherein The air blowing structure includes an air knife, which is used to communicate with an external air source, and the air knife extends along a second direction, which intersects with the first direction.
5. The molding apparatus of claim 1, wherein The air blowing structure includes an air inlet pipe and a plurality of first nozzles. The air inlet pipe is used to communicate with an external air source. The first nozzles are communicated with the air inlet pipe and are distributed along a second direction with the air inlet pipe. The second direction intersects with the first direction.
6. The molding apparatus of claim 1, wherein It also includes a cleaning structure, the outlet of which faces the lower mold and is used to clean the lower mold.
7. The forming apparatus of claim 6 wherein, The cleaning structure is connected to the air blowing structure.
8. The molding apparatus of claim 6, wherein The cleaning structure includes a cleaning pipe and a plurality of second nozzles. The cleaning pipe is used to communicate with an external air source or an external water source. The second nozzles are communicated with the cleaning pipe and are distributed along a second direction to the cleaning pipe. The second direction intersects with the first direction.
9. The molding apparatus of claim 1, wherein The slurry tank is equipped with a partition plate, which divides the interior of the slurry tank into a forming tank and a drainage tank. The lower mold is located in the forming tank, and the drainage tank is located on one side of the forming tank in a first direction. The drainage tank has a drainage outlet on its wall.
10. The molding apparatus of claim 9, wherein The two ends of the partition plate in the second direction are connected to the two inner sidewalls of the slurry tank in the second direction, and the lower end of the partition plate is inclined and connected to the inner sidewall of the slurry tank in the first direction. The second direction intersects with the first direction.
