Description

Technical Field

[0001] The utility model relates to the technical field of antibacterial coated paper production, in particular to a sizing assembly for antibacterial coated paper. Background Art

[0002] Coated paper belongs to a composite paper. Compared with ordinary paper materials, its main characteristics are waterproof, oil-proof and heat-sealable. According to the waterproof and oil-proof characteristics of coated paper, it is usually used for food to increase antibacterial effect. During the production process of coating the paper, a certain amount of glue needs to be coated on the paper surface, and the excess glue on the paper surface is removed by a scraping device, so that a uniformly thick glue layer is formed on the paper surface to achieve the waterproof and oil-proof effect of the composite paper.

[0003] When sizing the paper, the paper contacts with the coating roller to drive the coating roller to rotate, and the rotating coating roller dips the glue in the glue tank, so as to coat the glue on the paper surface. However, since the width of the paper is smaller than the length of the roller surface of the glue roller, when the coating roller drives the glue to be coated on the paper surface, the coating roller that does not contact the paper will, during the rotation process, under the action of centrifugal force, sprinkle the glue adhered to the surface, thus wasting the glue and soiling the sizing equipment and the working environment.

[0004] Therefore, there is an urgent need for a sizing assembly for antibacterial coated paper to solve the above problems. Content of the Utility Model

On one side of the glue tank 102 away from the bottom plate 101, two fixing plates 103 are fixedly connected. On the opposite sides of the two fixing plates 103, a glue coating roller 105 is connected through a rotating shaft 104. The bottom plate 101 is provided with a mounting frame 106, and the mounting frame 106 is provided with two guide rollers 107 and a glue scraping roller 108. The two guide rollers 107 and the glue scraping roller 108 are staggered and arranged at different heights. It also includes an anti-overflow component arranged on the two fixing plates 103 for preventing glue from overflowing at the part where the glue coating roller 105 does not contact the paper;

[0026] The anti-overflow component includes a semi-circular protective frame 201 fixedly connected to the side of the fixing plate 103 close to the glue coating roller 105. A protective cloth 202 is arranged inside the protective frame 201. One end of the protective cloth 202 is connected to the bottom wall of the protective frame 201 close to the fixing plate 103. The protective frame 201 is provided with a storage component for storing the protective cloth 202, and the fixing plate 103 is provided with a driving component for driving the protective cloth 202;

[0027] It should be noted here that: through the setting of the anti-overflow component, under the action of the driving component, the protective cloth 202 is used to shield and protect the surface of the glue coating roller 105 that is not in contact with the paper, thereby preventing the glue coating roller 105 that is not in contact with the paper from being scattered due to the centrifugal force during rotation, thereby avoiding glue waste while ensuring the cleanliness of the gluing equipment and working environment.

[0028] See also Figures 5-7 The storage assembly shown in the figure includes a plurality of U-shaped plates 301 slidably connected to the protection frame 201, each U-shaped plate 301 is connected to a storage roller 302 via a rotating rod, and the protection frame 201 is provided with an extrusion assembly for extruding each storage roller 302;

[0029] It should be noted here that: by setting the storage component, it is convenient to store the protective cloth 202, so as to adapt to the shielding and protection of the glue coating rollers 105 of different lengths while ensuring the neatness of the storage of the protective cloth 202.

[0030] See also Figure 6 and Figure 7 The extrusion assembly shown in the figure includes an extrusion tube 501 fixedly connected to the inner wall of the protection frame 201, and the extrusion tube 501 is slidably connected to an extrusion rod 502, one end of the extrusion rod 502 is connected to a side of the U-shaped plate 301 away from the storage roller 302, and the other end of the extrusion rod 502 is located inside the extrusion tube 501 and is fixedly connected to an extrusion plate 503, and the side of the extrusion plate 503 away from the extrusion rod 502 is fixedly connected to a spring 504, and the other end of the spring 504 is connected to the bottom wall of the extrusion tube 501;

[0031] It should be noted here that: the arrangement of the extrusion assembly provides a guiding and resetting function for the movement of the storage roller 302 .

[0032] See also Figure 6 In the figure, a plurality of abutting rods 4 are fixedly connected to the inner wall of the side of the protection frame 201 away from the extrusion tube 501, and each abutting rod 4 is staggered with the extrusion tube 501;

[0033] It should be noted here that: by setting the pressing rod 4, under the staggered pushing action of the storage roller 302 and the pressing rod 4, the protective cloth 202 is stored in the protective frame 201 in a wave form, thereby realizing the storage of the protective cloth 202.

[0034] Working principle: When gluing coated paper, the feeding device usually provides paper to a feeding roller wound with paper, and the paper is fed along the feeding roller. Figure 2Travel in the direction of the arrow in it. During the paper transmission process, the paper first contacts the glue applicator roller 105, drives the glue applicator roller 105 to rotate, the glue applicator roller 105 dips the glue in the glue tank 102, and coats it on the surface of the paper. Then the paper passes through the guide roller 107 and the scraping roller 108 to scrape off the excess glue on the surface of the paper, so that a glue layer with a uniform thickness is formed on the surface of the paper, thereby ensuring the quality of gluing the paper. In the existing publicly known technology, CN218945499U, a glue application assembly for an antibacterial laminated paper, has specific descriptions and introductions for the glue application operation method and structure of the paper, and will not be elaborated here;

[0035] Moreover, when the glue applicator roller 105 applies glue to the paper, according to the width of the paper, the surface of the glue applicator roller 105 that does not abut against the paper can be shielded to prevent overflow. During the process of shielding and preventing overflow on the surface of the glue applicator roller 105 that does not abut against the paper, the driving component drives the protective cloth 202 to move out of the protective frame 201, so as to avoid the glue applicator roller 105 that does not contact the paper from splashing the glue adhered to the surface due to the action of centrifugal force during rotation, thereby avoiding glue waste and ensuring the cleanliness of the gluing equipment and the working environment;

[0036] Moreover, during the process of the protective cloth 202 moving out, under the stretching action, it will squeeze the storage roller 302. When the glue application operation on the paper is completed and the driving component drives the protective cloth 202 to contract, it will, under the elastic action of the squeezing component, push the storage roller 302 to reset. Thus, under the alternating pushing action of the storage roller 302 and the abutting rod 4, the protective cloth 202 is stored in the protective frame 201 in a wavy form, thereby realizing the storage of the protective cloth 202.

On the side of the driving ring 601 away from the glue applicator roller 105, three connecting plates 602 are annularly arranged. One of the three connecting plates 602 in the middle is rotatably connected with a threaded rod 603. The threaded rod 603 is threadedly connected to the fixing plate 103.

The two T-shaped guide rods 605 are slidably connected to the fixing plate 103;

[0039] It should be noted here that: through the setting of the driving component, when the rocking wheel 604 rotates, the threaded rod 603 will be driven to rotate. Under the action of the threaded meshing transmission between the threaded rod 603 and the fixed plate 103 and the guiding action of the T-shaped guiding rod 605, the driving ring 601 will be driven to move closer to or away from the fixed plate 103, thereby further stretching or contracting the protective cloth 202.
