Abstract
Description
Technical Field
[0001] This utility model relates to the field of printing equipment technology, and in particular to a pre-treated perforated base paper forming roller. Background Technology
[0002] Cake cup holders are paper cups used for cake making. These cups are formed by folding and processing paper sheets (such as perforated paper). Perforated paper has various patterns for decorating the cups. The patterns on the perforated paper need to be pressed by a perforated paper forming roller. Traditional perforated paper forming rollers generally have four flush perforated patterns so that each rotation of the forming roller produces four perforated paper sheets. However, because the perforated patterns on the forming roller are flush, the space occupied by the two flush patterns is relatively large, which increases the width of the paper sheet and wastes production materials. Although existing perforated paper forming rollers have staggered perforated patterns to reduce the width of the processed paper sheet and waste of production materials, the staggered perforated patterns also make it difficult to cut the formed paper sheet to specifications in one go in the subsequent cutting process. Multiple cutting blades are needed for multiple cutting operations, or workers need to manually complete the cutting of the remaining parts, which affects the efficiency of subsequent processing. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a pre-processed perforated paper forming roller. The roller body has a staggered perforation pattern between two columns of embossing, which reduces the width of the roller body and the width of the processed paper. Furthermore, the roller body is equipped with cutting grooves, which pre-cut one column of the perforation pattern on the processed paper during the forming process. This allows for a one-time cutting process in the subsequent cutting process, eliminating the need for multiple cutting operations or manual cutting of the remaining portion by workers, thereby improving subsequent processing efficiency.
[0004] A pre-treated perforated backing paper forming roller includes a roller body. The roller surface of the roller body is provided with two rows of embossing along the length direction, and each row of perforated embossing includes multiple perforated patterns. The two rows of embossing are staggered vertically and horizontally on the adjacent sides of the two rows of embossing. A cutting edge is provided on the edge of one perforated pattern of one row of embossing.
[0005] Preferably, the device further includes the mounting shafts, two of which are connected to the two ends of the roller body respectively, and the mounting shafts are provided with mounting keyways.
[0006] Preferably, the mounting shaft is provided with a mounting protrusion, and the mounting shaft is connected to the end of the roller body through the mounting protrusion.
[0007] Preferably, the cutting grooves extend along the edge shape of the openwork pattern, and the perimeter of the cutting grooves is half the perimeter of the openwork pattern.
[0008] Preferably, a forming gap is left between the two rows of embossed openwork patterns, and the forming gap is distributed in a snake shape.
[0009] The beneficial effects of this utility model are: the pre-treated perforated bottom paper forming roller, through the cooperation of the roller body and the embossing, allows the roller body to stagger the perforated patterns between the two columns of embossing, which reduces the width of the roller body and the width of the processed paper. In addition, the roller body is provided with cutting grooves, which pre-cut one column of the perforated pattern of the processed paper during the forming process. In this way, the paper can be cut in one go in the subsequent cutting process, without the need for multiple cutting operations or manual cutting of the remaining part by the workers, thus improving the efficiency of subsequent processing.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.
[0015] like Figures 1 to 3 As shown, a pre-treated perforated bottom paper forming roller includes a roller body 1. The roller surface of the roller body 1 is provided with two rows of embossing along the length direction, and each row of perforated embossing includes multiple perforated patterns 2. The two rows of embossing are staggered vertically, and the adjacent sides of the two rows of embossing are staggered horizontally. A cutting knife pattern 3 is provided on the edge of a perforated pattern 2 of one row of embossing.
[0016] The working principle of the pre-treated perforated paper forming roller described in this utility model is achieved through the cooperation of the roller body 1 and the embossing, such as... Figures 1 to 3As shown, the roller 1 has staggered openwork patterns 2 between two rows of embossing, which reduces the width of the roller 1 and the width of the paper sheet. The roller 1 is also equipped with cutting grooves 3. Each row of embossing is illustrated with two openwork patterns 2. Therefore, cutting grooves 3 can be set on one openwork pattern 2 in one row of embossing. During the forming process, the roller 1 rotates once to form a paper sheet with four staggered openwork patterns 2. One row of openwork patterns 2 in one row of the paper sheet is pre-cut. In this way, in the subsequent cutting process, only one side of the paper sheet needs to be cut to complete the one-time cutting. Compared with the traditional openwork bottom paper roller, this pre-processed openwork bottom paper forming roller pre-cuts the paper sheet during forming. In the subsequent process, there is no need to perform multiple cutting operations or for the staff to manually complete the cutting of the remaining part, thus improving the efficiency of subsequent processing.
[0017] The pre-treated perforated paper forming roller of this utility model also includes the mounting shaft 4. Two mounting shafts 4 are connected to the two ends of the roller body 1, and each mounting shaft 4 is provided with a mounting keyway 6. Each mounting shaft 4 is provided with a mounting protrusion 5, and the mounting shaft 4 is connected to the end of the roller body 1 through the mounting protrusion 5. Further, the cutting groove 3 extends along the edge shape of the perforated pattern 2, and the perimeter of the cutting groove 3 is half the perimeter of the perforated pattern 2. Even further, a forming gap 7 is left between the two rows of embossed perforated patterns 2, and the forming gap 7 is distributed in a serpentine shape. Figures 1 to 3 As shown, the two ends of the roller body 1 are installed via the mounting shaft 4. The mounting protrusion 5 facilitates the positioning of the roller body 1, and the mounting keyway 6 facilitates the installation and connection of the mounting shaft 4. The openwork patterns 2 between the two rows of embossing are staggered and the forming gap 7 is serpentine, which can reduce the width of the roller body 1 and the width of the paper sheet, thereby reducing the cost of processing materials. During the forming process, the cutting blade 3 cuts half of the edge of one row of embossing patterns 2 of the paper sheet. In this way, in the subsequent cutting process, it is only necessary to cut from the gap between the openwork patterns 2 of the other row of embossing to cut the paper sheet at once without affecting the openwork patterns 2 of the paper sheet, thereby improving the efficiency of subsequent processing.
[0018] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
