AI Technical Summary
Dust easily adheres to the surface of PVC sheets during embossing, causing the printed patterns to become blurry and affecting the embossing effect.
An ion fan is used to eliminate static electricity on the sheet surface, and a suction element is used to remove dust. The suction element also increases the airflow velocity on the embossed surface of the sheet, causing the sheet to bulge upwards and unfold under air pressure. A limiting structure is used to prevent it from deviating from the track.
It effectively reduces dust adhesion, keeps the sheet unfolded, improves the pattern pressing effect, prevents deviation from the track, and adapts to sheets of different thicknesses.

Abstract
Claims
1. A PVC sheet embossing machine, comprising a frame (1), an embossing assembly (2) lifted and slidably connected to the frame (1), a drive roller (3) and a take-up roller (4) rotatably connected to the frame (1), wherein the drive roller (3) pulls the PVC sheet to move towards the take-up roller (4), and the embossing assembly (2) presses a pattern on the surface of the sheet, characterized in that: The frame (1) is provided with an air extraction element (5) and an ion fan (6). The ion fan (6), the air extraction element (5) and the embossing assembly (2) are distributed in sequence along the traction direction of the PVC sheet. The air extraction element (5) is connected to an air extractor (52). The air inlet (51) of the air extraction element (5) and the air outlet of the ion fan (6) are both facing the embossed surface of the PVC sheet.
2. A PVC sheet embosser as claimed in claim 1, wherein: There are two suction elements (5), which are symmetrically distributed on both sides of the PVC sheet in the width direction. The length of the suction element (5) is parallel to the PVC sheet, and the two sides of the PVC sheet slide against the suction element (5) on the corresponding side.
3. A PVC sheet embosser as claimed in claim 2, wherein: The air extraction element (5) is provided with a pressure edge (53), the air inlet (51) is located above the pressure edge (53), the pressure edge (53) and the frame (1) are spliced to form a pressure groove (54), the pressure groove (54) is for the edge of the PVC sheet to be inserted.
4. A PVC sheet embosser as claimed in claim 3, wherein: The air extraction element (5) is slidably connected to the frame (1), and the frame (1) is provided with a drive component (7), which drives the air extraction element (5) to move up and down.
5. A PVC sheet embosser as claimed in claim 4, wherein: The driving component (7) is a support airbag (71). An air nozzle (72) is fixed on the support airbag (71) to connect the inner cavity of the support airbag (71) with the outside. The support airbag (71) is deflated or inflated through the air nozzle (72). The support airbag (71) supports the suction element (5).
6. A PVC sheet embosser as claimed in claim 5, wherein: The frame (1) is provided with an upward-facing lifting groove (111), and the support airbag (71) supports the suction element (5) so that the suction element (5) slides up and down in the lifting groove (111).
7. A PVC sheet embosser as claimed in claim 3, wherein: The embossing assembly (2) is provided with a pressure block (211), which is located between the air extraction element (5) and the embossing assembly (2). A limiting gap is formed between the pressure block (211) and the frame (1) for the PVC sheet to pass through.
8. A PVC sheet embossing machine according to claim 1 or 2, characterized in that: The air inlet (51) of the air extraction element (5) is elongated, and the length of the air inlet (51) is parallel to the length of the air extraction element (5).
9. A PVC sheet embosser as claimed in claim 1, wherein: The outlet of the ion fan (6) is tilted away from the embossing assembly (2).
