Description

Technical Field

[0001] This utility model relates to the field of hollow board production technology, specifically a hollow board extrusion mold. Background Technology

[0002] Hollow core board is a new type of material that is lightweight, non-toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion-resistant, and available in a variety of colors. Compared with cardboard structures, hollow core board has advantages such as moisture resistance and corrosion resistance, and it is recyclable, showing a trend of gradually replacing paper corrugated boards. In the processing of hollow core board, an extrusion operation is required to complete the molding of PVC hollow core board. Existing extrusion equipment will transport raw materials containing air bubbles to the extrusion mechanism during the feeding stage, which will increase the probability of defective products.

[0003] Chinese patent discloses an extrusion device for processing PVC hollow boards (authorization announcement number CN217670951U). This patented technology extrudes raw materials to reduce air bubbles in the raw materials during the feeding stage. It is equipped with an extrusion mechanism. When the raw materials enter the collection box from the feeding mechanism, the detector detects the concentration of the raw materials to ensure that the raw materials are at the most suitable concentration for the extrusion operation. Finally, the raw materials are extruded through the extrusion plate to complete the extrusion operation.

[0004] However, it has certain drawbacks: during the melting and extrusion process, the raw materials may contain impurities or incompletely melted particles. These substances are prone to accumulate at the extrusion nozzle of the extrusion plate and gradually form residues. In addition, the temperature of the part near the outside of the extrusion nozzle of the extrusion plate is relatively low, which can also lead to the cooling residue of the raw materials, thus producing residues. Over time, these residues will increase, which will not only cause blockage of the extrusion nozzle of the extrusion plate, but may also affect the production quality of subsequent hollow boards.

[0026] The raw material is squeezed into the extrusion groove 7 through the extrusion hole 9 and then extruded.

[0027] exist Figures 2-4In the middle: A slag removal mechanism 10 is provided on the upper surface of the hollow plate extruder 6. The slag removal mechanism 10 includes a Z-shaped plate 11. The lower end of the Z-shaped plate 11 is fixed to the upper surface of the hollow plate extruder 6. A first telescopic cylinder 12 is fixed to the upper surface of the Z-shaped plate 11.

A scraper ring 15 is fixed to the telescopic end of the second telescopic cylinder 14. Multiple suction holes 16 are opened on the left side surface of the second telescopic cylinder 14. An external suction component 17 is provided, which includes a suction cylinder 18. A filter plate 19 is movably connected to the upper end of the front surface of the suction cylinder 18, and a fan 20 is fixedly connected to the upper end of the suction cylinder 18.

[0028] The scraper ring 15 fits into the cavity of the extrusion groove 7 located outside the support block 8;

[0029] Both the first telescopic cylinder 12 and the second telescopic cylinder 14 are preferably pneumatic cylinders or electric cylinders;

[0030] After the first telescopic cylinder 12 extends, the scraper ring 15 descends to the cavity directly opposite the extrusion groove 7 located outside the support block 8;
