[0022] The present invention will be further described below with reference to the embodiments.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0025] Example

[0026] During the calendering process, paper scraps or impurities may be carried on both sides of the paper, which may be easily pressed and fixed on the paper surface during subsequent calendering, affecting the calendering quality. Common prior art uses a scraping structure to scrape both sides of the paper. However, the scraping structure of the prior art is complex, which is not conducive to production and processing, and the manufacturing cost of the structure is high. In addition, the paper is prone to deviation during calendering, which in turn affects the quality of the subsequent winding operation.

[0027] To do this, see Figure 1-5 The utility model provides a paper product processing calender, comprising: a calender body 1, and a scraping type correcting member is installed on the front side wall of the calender body 1; the scraping type correcting member can, on the one hand, scrape impurities on both sides of paper of different thicknesses, and on the other hand, can guide and limit paper of different widths.

[0028] Further as Figure 1-5As shown, it is worth mentioning that in order to be able to perform double-sided scraping of paper scraps or impurities for papers of different thicknesses, and to be able to perform guiding, limiting and anti-deviation for papers of different widths, a scraping type correction member is provided, which includes a mounting plate 2 fixed by two bolts on the front side wall of the calender body 1, and a C-shaped plate 22 is fixed to the top of a support frame 21 with an L-shaped structure in vertical section on the front side wall of the mounting plate 2, and scrapers 24 are integrally formed at both ends of the front side of the C-shaped plate 22 through a first weakening groove 23, and a scraping portion 26 is provided at the opposite end of the two scrapers 24, and the two scrapers 24 are symmetrically arranged, and a plurality of equidistant lightweight grooves 25 are provided on the top and bottom of the C-shaped plate 22, and a middle portion of the C-shaped plate 22 is provided. A slide groove with an I-shaped structure in vertical cross-section is provided, and two symmetrically distributed sliders 27 are slidably connected in the slide groove. The vertical cross-sections of the sliders 27 are all I-shaped structures. The front ends of the two sliders 27 are fixed with L-shaped spring pieces 28 near their bottom positions. The bottom corners of the L-shaped spring pieces 28 are provided with second weakening grooves 29. The tops of the L-shaped spring pieces 28 are provided with raised portions 210. The two L-shaped spring pieces 28 are fixed with a card block 211 on one side wall facing the inner side wall of the C-shaped plate 22. A plurality of card slots 213 that cooperate with the card block 211 are provided on the inner side wall of the C-shaped plate 22. The height of the card slots 213 is greater than the height of the card block 211. The ends of the two card blocks 211 away from the L-shaped spring pieces 28 are provided with symmetrically distributed inclined surfaces 212.

[0029] The setting of the lightweight groove 25 makes the weight of the integrated structure design of the entire C-shaped plate 22 and the two scrapers 24 lighter; in addition, when the first weakened groove 23 is deformed in the figure, when there is no paper between the scraping parts 26 of the two scrapers 24, the scraping parts 26 of the two scrapers 24 will contact each other under the reverse action of the first weakened groove 23; the design of the second weakened groove 29 is to make the L-shaped spring piece 28 more easily deformed; and at the same time, Figure 3 As shown in , the bottom end of the card block 211 contacts the bottom of the card slot 213 , and the height inside the card slot 213 is greater than the height of the card block 211 . The design of the inclined surface 212 is to make it easier and faster for the card block 211 to be inserted into the card slot 213 .

[0030] In summary: when using the paper product processing calender, the first weakening groove 23 is set so that the ends of the two scrapers 24 that are away from each other can be deformed between the first weakening groove 23 and the C-shaped plate 22, so that it is convenient to scrape paper scraps or impurities on both sides of the surface of paper of different thicknesses. Its structural design is simple and the production cost is low. In addition, in order to be able to guide and limit paper of different widths, the L-shaped spring piece 28 can be manually moved so that the bottom of the L-shaped spring piece 28 is deformed through the second weakening groove 29, and the card block 211 is disengaged from the corresponding card slot 213, so that the two sliders 27 can move relative to each other or away from each other in the slide groove, so as to facilitate the guidance and limitation of both sides of paper of different widths, and effectively prevent deviation during the calendering process and affect the quality of subsequent winding operations.
