During operation, the annular seat 401 supports the middle part of the pressing hot-pressing roller 61, and the problem that the two ends of the pressing hot-pressing roller 61 are connected to influence scraping of the scraper 71 on the excess material on the composite bed cover is avoided.

Referring to fig. 3, 5, 10 and 12, the recycling set includes a limiting chute 701, a waste bin 702, a slider 703, a blanking plate 704 and a supporting plate 705, an arc-shaped through groove is formed in the left side of one end of the arc-shaped cover 4 close to the fixing frame 1, the limiting chute 701 which is arranged in an arc shape and communicated with the arc-shaped through groove is formed in the arc-shaped cover 4, the waste bin 702 is placed on the arc-shaped through groove, the slider 703 which is in sliding fit with the limiting chute 701 is installed at the lower end of the waste bin 702, the waste bin 702 is located under the driving ring 70, the blanking plate 704 is installed in the waste bin 702 through a support plate, the supporting plate 705 is installed in the waste bin 702 through connecting strips which are symmetrically arranged front and back, the supporting plate 705 is located under the blanking plate 704, and the blanking plate 704 and the supporting plate 705 are both located on one side of the driving ring 70 close to the scraper 71.

During operation, when the scraping plate 71 after the glue scraping rotates to be in contact with the abutting plate 705, the abutting plate 705 abuts against the scraping plate 71, so that the scraping plate 71 rotates to be in a vertical state, meanwhile, the blanking plate 704 removes scraped remainders on the scraping plate 71, so that the remainders fall into the remainders box 702 to facilitate next use of the scraping plate 71, and the abutting plate 705 is fixedly installed through the connecting strips which are symmetrically arranged in the front and back, so that the removed remainders can smoothly fall into the remainders box 702.

Referring to fig. 10, the lower ends of the abutting plate 705 and the blanking plate 704 are inclined to the lower right to facilitate removing the excess material on the scraper 71.

Referring to fig. 9, the two opposite ends of the residue box 702, which are close to the arc-shaped end surface of the main hot pressing roller 6, are located below the hot pressing roller 61, so that the residue box 702 can collect the residue.

A composite bed cover pressing manufacturing process comprises the following steps: s1, bottom surface gluing: the bottom surface 10 of the composite bed cover is fed between the glue spreader 21 and the compression roller 22 from the left side, glue in the glue solution tank 20 is adhered to the surface of the glue spreader 21 when the glue spreader 21 rotates, then the glue spreader 21 coats the glue solution on the lower end surface of the bottom surface 10 of the composite bed cover, and then the bottom surface 10 of the composite bed cover coated with the glue solution moves rightwards under the driving of an external existing winding mechanism.

S2, pressing a bed cover: and when the bottom surface 10 after gluing moves towards the right side, the bottom surface is attached and adhered to the fabric 11 to form a bed cover, and when the bed cover bypasses the main hot pressing roller 6, hot pressing operation is realized through the rolling fit of the main hot pressing roller 6 with the temperature of 140 ℃ and the pressing hot pressing roller 61 with the temperature of 140 ℃.

S3, scraping residual glue: the rotating shaft 5 rotates and simultaneously drives the scraper 71 to rotate reversely along the main hot pressing roller 6 through the meshing action between the main gear 75 and the inner gear ring 74, the scraper 71 scrapes off glue solution extruded in the laminating process of the composite bed cover, when the scraper 71 after the glue scraping rotates to be in contact with the resisting plate 705, the resisting plate 705 resists against the scraper 71, so that the scraper 71 rotates to be in a vertical state, and meanwhile, the blanking plate 704 removes scraped surplus materials on the scraper 71, so that the surplus materials fall into the surplus box 702.

S4, cold-pressing and winding: and (4) carrying out cold pressing treatment on the composite bed cover subjected to the hot pressing by using a cold pressing mechanism, and finally winding or cutting the pressed composite bed cover.
