Through the vibrator part, the ear seat part I swings on the ear seat part II. Under the action of the screen plate part, the raw material particles of the core layer body are distributed on the blank plate of the expansion layer body. Under the action of the front heater corresponding to the second cylinder part, the raw material particles of the core layer body are heat-melted and combined to obtain the blank plate of the core layer body. The raw material particles of the surface layer body are conveyed to the third cylinder part through the material conveying part. Through the vibrator part, the ear seat part I swings on the ear seat part II. Under the action of the screen plate part, the raw material particles of the surface layer body are distributed on the blank plate of the core layer body. Under the action of the front heater corresponding to the third cylinder part, the raw material particles of the surface layer body are heat-melted and combined to obtain the blank plate of the surface layer body, thereby obtaining a three-layer roll-pressed blank plate. Through the movement of the conveying scraper part, the three-layer roll-pressed blank plate is placed on the guiding plate. Through the rear heater, the three-layer roll-pressed blank plate is heated. The hot three-layer roll-pressed blank plate is conveyed to between roller part I and roller part II through the guiding plate. Under the rotation action of roller part I, roller part II rotates in the receiving hole body IV, so that the hot three-layer roll-pressed blank plate moves between roller part I and roller part II, thereby making the hot three-layer roll-pressed blank plate undergo roll-compaction treatment. After being processed between roller part I and roller part II, a blank plate for stretching a plastic grille is obtained. When the preparation of the blank plate for stretching a plastic grille is completed, make the drive motor of the active sprocket part, the rear heater, the drive motor of roller part I, the front heater, the material conveying part, and the vibrator part be in the non-working state. When the screw part I rotates in the receiving hole body I and the receiving hole body III, make the seat part I move up and down, and make roller part II move in the receiving hole body II to adjust the height of the seat part I, thereby adjusting the distance between roller part I and roller part II to make the distance between roller part I and roller part II correspond to the thickness of the blank plate for stretching a plastic grille.

[0077] The technical effect of the above technical solution is as follows: It realizes the preparation of billets by triple-roll pressing of raw material particles.

[0078] The present invention is designed with the following steps: Place the film rolls of the core layer body with unwinding shafts into the U-shaped openings of the support beam part I respectively. Keep the drive motors of the active sprocket part, the rear heater, the drive motor of the roller part I, the front heater, the feeding part, the vibrator part, and the drive motor of the front conveying plate roller in working state. The conveying scraper part rotates between the active sprocket part, the driven sprocket part, and the supporting roller. Place the hot-melt plate-shaped body of the surface layer body on the conveying scraper part. Place the hot-melt plate-shaped body of the expansion layer body between the supporting plate part and the front conveying plate roller. Unwind the film roll of the core layer body on the first unwinding shaft, and place the first film of the core layer body on the hot-melt plate-shaped body of the surface layer body. Under the action of the front heater corresponding to the first unwinding shaft, heat the first film of the core layer body on the hot-melt plate-shaped body of the surface layer body. Under the action of the roller part III corresponding to the first unwinding shaft, roll-press the first film of the core layer body on the hot-melt plate-shaped body of the surface layer body, so as to thermally fuse the first film of the core layer body to the hot-melt plate-shaped body of the surface layer body. Unwind the film roll of the core layer body on the subsequent unwinding shaft, and place the film of this core layer body on the already thermally fused film of the core layer body. Under the action of the front heater corresponding to the subsequent unwinding shaft, heat the film of this core layer body on the already thermally fused film of the core layer body. Under the action of the roller part III corresponding to the subsequent unwinding shaft, roll-press the film of this core layer body on the thermally fused film of the core layer body, so as to thermally fuse the film of this core layer body to the already thermally fused film of the core layer body. Thus, thermally fuse the films of multiple core layer bodies to the hot-melt plate-shaped body of the surface layer body to obtain a double-layer roll-pressed blank plate. Through the movement of the conveying scraper part, place the double-layer roll-pressed blank plate on the guiding plate. The hot-melt plate-shaped body of the expansion layer body moves on the supporting plate part through the front conveying plate roller 9, so that the hot-melt plate-shaped body of the expansion layer body enters the roller part IV and the roller part V. Through the rotation of the roller part IV and the roller part V, place the hot-melt plate-shaped body of the expansion layer body on the already thermally fused film of the core layer body of the double-layer roll-pressed blank plate on the guiding plate to obtain a three-layer roll-pressed blank plate. Heat the three-layer roll-pressed blank plate through the rear heater. The hot three-layer roll-pressed blank plate is conveyed through the guiding plate to between the roller part I and the roller part II. Under the rotation action of the roller part I, the roller part II rotates in the receiving hole body IV, so that the hot three-layer roll-pressed blank plate moves between the roller part I and the roller part II, so that the hot three-layer roll-pressed blank plate is subjected to roll-compaction treatment. After being processed between the roller part I and the roller part II, obtain a blank plate for stretching a plastic grid. When the preparation of the blank plate for stretching a plastic grid is completed, keep the drive motors of the active sprocket part, the rear heater, the drive motor of the roller part I, the front heater, the feeding part, the vibrator part, and the drive motor of the front conveying plate roller in non-working state. When the nut part rotates on the screw part II, adjust the distance between the frame part and the transverse part of the support beam part II, adjust the compression state of the spring part, and adjust the roll-pressing state of the roller part III and the already thermally fused film of the core layer body.
