Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing equipment, in particular to a flattening device for preventing uneven paper from being scratched during a coding process. Background Art
[0002] Paper will deform when it is affected by air humidity, squeezing, etc. During the printing process, Figure 1 , 2 The nozzle 2 is located above the conveying platform 1, and the gap between the nozzle 2 and the conveying platform 1 is very small. When the deformed paper 3 is conveyed by the conveying platform 1 to the bottom of the nozzle 2, it is very easy to cause the paper 3 to rub against the nozzle 2, thereby causing the two-dimensional code to be scratched, the nozzle to be scratched, etc., resulting in a large number of waste products caused by inkjet printing. In response to this problem, the technicians have improved the existing equipment, and therefore proposed a flattening device to prevent the uneven paper from being scratched during the inkjet printing process. Utility Model Content
[0003] The utility model aims to provide a flattening device for preventing uneven paper from being scratched during the coding process. A limiting ring is arranged around the nozzle, and a gravity ball is movably placed in the limiting ring. During production, the gravity ball presses the paper for transportation, so that the paper does not scratch the nozzle.
[0004] To achieve the above-mentioned purpose, the utility model provides a flattening device for preventing uneven paper from being scratched during the coding process, comprising a limit ring and a gravity ball. A plurality of the limit rings are used to be distributed around the nozzle, and there is a gap between the limit ring and the working surface of the conveying platform. The gravity ball is movably placed in the limit ring.
[0005] The plurality of limit rings are connected to form an integral structure through a connecting piece, and mounting plates are respectively connected to both ends of the integral structure, and the mounting plates are connected to a mounting seat installed on the conveying platform.
[0006] The mounting seat comprises a supporting plate and an ear plate, the ear plate is fixedly connected to the supporting plate, and the mounting plate and the ear plate are connected by bolts.
[0007] The holes on the ear plate or the mounting plate for passing the bolts are longitudinal long holes.
[0008] The gravity ball is a glass ball or a steel ball.
[0009] The limiting rings are connected by connecting pieces to form a matrix structure.
[0010] At least four limiting rings are distributed around each nozzle.
[0011] Compared with the prior art, the utility model has the following technical effects:
[0012] The utility model arranges a limit ring around the nozzle, and movably places a gravity ball in the limit ring. The diameter of the gravity ball is smaller than the inner diameter of the limit ring, so that the gravity ball can freely fall and roll in the limit ring. When in production and use, the gravity ball presses the paper to be conveyed, thereby flattening the paper on the upper working surface of the conveying platform, so that the paper does not scratch the nozzle during conveyance.

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.
[0024] See also Figure 3-6A flattening device 10 for preventing uneven paper from being scratched during the coding process includes a limit ring 11 and a gravity ball 12. A plurality of limit rings 11 are distributed around the nozzle 2. There is a gap between the limit ring 11 and the working surface of the conveying platform 1. The gravity ball 12 is movably placed in the limit ring 11. By arranging the limit ring 11 around the nozzle 2 and movably placing the gravity ball 12 in the limit ring 11, the gravity ball 12 presses the paper 3 for conveying during production and use, so that the paper 3 does not scratch the nozzle 2.
[0025] Specifically, the diameter of the gravity ball 12 is smaller than the inner diameter of the limiting ring 11, so that the gravity ball 12 can fall and roll freely in the limiting ring 11. When falling, it presses the paper, and when rolling, it facilitates the paper to be transported downstream.
[0026] See also Figure 5 The plurality of limit rings 11 are connected to form an integral structure through a connecting piece 13, and mounting plates 14 are respectively connected to both ends of the integral structure, and the mounting plates 14 are connected to mounting seats 15 installed on the conveying platform 1. Through the above structure, the limit rings 11 are connected to the conveying platform 1. Specifically, the mounting seats 15 are installed on the metal frames on both sides of the conveying platform 1.
[0027] Furthermore, the mounting seat 15 includes a support plate 151 and a lug plate 152 . The lug plate 152 is fixedly connected to the support plate 151 . The mounting plate 14 and the lug plate 152 are connected via bolts 153 .
[0028] Furthermore, the hole on the ear plate 152 or the mounting plate 14 for passing the bolt 153 is a longitudinal long hole, so as to facilitate the adjustment of the distance between the bottom of the limit ring 11 and the upper working surface of the conveying platform 1 .
[0029] Preferably, the gravity ball 12 is a glass ball or a steel ball.
[0030] In a preferred embodiment, see Figure 5 , 6 The limiting rings 11 are connected to each other by connecting members 13 to form a matrix structure. Specifically, at least four limiting rings 11 are distributed around each nozzle 2 , and each nozzle 2 is located in an area surrounded by the four limiting rings 11 .
[0031] The working principle or action process of the utility model is as follows:
[0032] When in use, the paper 3 is conveyed by the gravity balls 12 located in the four limiting rings 11 distributed around each nozzle 2, thereby flattening the paper 3 on the upper working surface of the conveying platform 1, so that the paper 3 does not rub against the nozzle 2 during conveyance.
