Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a printhead arrangement and carriage frame fixing structure for a digital printing device. Background Technology

[0002] Digital printing equipment primarily prints images onto the substrate by inkjet printing from printheads. Under the control of the inkjet controller, ink is ejected from the nozzles of the printhead at a certain pressure and then printed onto the substrate. The arrangement of the printheads and the mounting and fixing of the carriage are particularly important. Different printhead arrangements and carriage mounting precision directly affect whether the printing effect is normal or abnormal, as well as whether the printing efficiency is improved.

[0003] In existing technologies, traditional printheads are arranged side-by-side or staggered laterally. The carriage is fixed to the side of a long beam, and the printhead moves back and forth on the guide rails of the long beam to achieve the purpose of printing. The disadvantages of this technology are that there are obvious pits at the printhead splicing points, the printhead passes significantly affect the image quality, minor printhead needle breakage is more noticeable after transfer, black and white lines are prone to appear at the overlapping positions of the printheads, which seriously affects the print quality, the printhead lines are blurry, the edges are obviously blurry and the landing points are uneven, and the printing speed is too slow, which affects the printing efficiency. The installation accuracy of the carriage is not high. When the front and rear width of the carriage increases, the carriage cannot maintain a good level and flatness, and there is a risk of sagging at the outer end. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the technology where the traditional printhead arrangement is side-by-side or horizontally staggered, the carriage is fixed to the side of a long beam, and the printhead moves back and forth on the guide rail of the long beam to achieve the purpose of printing. The technical disadvantages are that the printhead splicing points are obvious, the printhead pass significantly affects the image quality, minor printhead needle breakage is more noticeable after transfer, black and white lines easily appear at the overlapping positions of the printheads, which seriously affects the print quality, the printhead lines are blurry, the edges are obviously blurry and the landing points are uneven, the printing speed is too slow, which affects the printing efficiency, the carriage installation accuracy is not high, and when the front and rear width of the carriage increases, the carriage cannot maintain a good horizontal plane, and there is a risk of sagging at the outer end. Therefore, this invention proposes a printhead arrangement and carriage fixing structure for digital printing equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a carriage fixing structure for a digital printing device, including a printing base, a bottom beam installed through the upper middle part of the printing base, long beam support blocks fixedly connected to both ends of the upper end of the bottom beam, a long beam fixedly connected between the two long beam support blocks, guide rails fixedly connected to both sides of the lower middle part of the long beam, a carriage frame arranged above the printing base, the long beam passing through the carriage frame, and the carriage frame slidably connected to the guide rails.

[0006] Preferably, a back plate is fixedly connected to one side of the trolley frame.

[0007] Preferably, a main platform is installed on the upper end of the printing base, and leg side plates are fixedly connected to both sides of the printing base.

[0008] Preferably, each of the four corners at the lower end of the printing base is fixedly connected to a support leg.

[0009] Preferably, both sides of the lower end of the printing base are fixedly connected to movable wheels.

[0010] A printhead arrangement structure for a digital printing device includes a carriage base and printheads. The carriage base is fixedly connected to a carriage frame, and the printheads are fixedly connected to the carriage base. The printheads are arranged in a longitudinally staggered pattern.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] This invention improves printing quality and installation accuracy by using a longitudinally staggered arrangement of printheads and a through-type installation of the long beam and carriage frame. This solves the problems of poor printing quality and low printing efficiency. The design also reduces labor and material costs. Furthermore, it addresses issues such as noticeable pitting at printhead splicing points, significant impact of printhead passes on image quality, noticeable minor printhead needle breakage after transfer, black and white lines appearing at overlapping printhead positions, blurred lines, uneven edges, slow printing speed affecting efficiency, and inaccuracy caused by an unreasonable carriage frame fixing method.

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1: As Figure 1 - Figure 2 As shown, this utility model provides a carriage fixing structure for a digital printing device, including a printing base 1. A bottom beam 6 is installed through the upper middle part of the printing base 1. Long beam support blocks 7 are fixedly connected to both ends of the upper end of the bottom beam 6. A long beam 8 is fixedly connected between the two long beam support blocks 7. Guide rails 11 are fixedly connected to both sides of the lower middle part of the long beam 8. A carriage 9 is set above the printing base 1. The long beam 8 passes through the carriage 9. The carriage 9 is slidably connected to the guide rails 11. A carriage back plate 10 is fixedly connected to one side of the carriage 9. A main platform 2 is installed at the upper end of the printing base 1. Leg side plates 3 are fixedly connected to both sides of the printing base 1. Support legs 4 are fixedly connected to the four corners of the lower end of the printing base 1. Moving wheels 5 are fixedly connected to both sides of the lower middle part of the printing base 1.

[0020] The specific settings and functions of this embodiment will be described in detail below. By setting the long beam 8 and installing it through the trolley frame 9, and cooperating with the guide rail 11, the installation reference is fixed at the bottom of the long beam 8, which greatly saves installation space, improves installation accuracy, and makes it less prone to tilting and more stable in use.

[0022] The overall effect of this embodiment is that by arranging the printheads 13 vertically in a staggered manner, it solves the problems of poor printing effect and low printing efficiency. This reduces labor and material costs in the design. It also solves the problems of obvious pitting at the printhead splicing points, the significant impact of printhead pass lines on the image quality, the noticeable transfer of minor printhead needle breakage, the tendency for black and white lines to appear at the overlapping positions of the printheads, which seriously affects the image quality, the blurry lines, the obvious blurring and uneven drop points at the edges, and the slow printing speed that affects printing efficiency.
