Description

Technical Field

[0001] The utility model relates to the technical field of printers, in particular to a high-precision double-sided spraying printer. Background Art

[0002] A double-sided spraying printer is a printer that can automatically complete double-sided printing tasks. Currently, double-sided spraying printers usually adopt two printing head groups to perform double-sided printing vertically or horizontally. In actual applications, the following technical defects exist:

[0003] (1) When performing double-sided printing vertically or horizontally, a longer layout is required, and the distance between the two printing head groups is relatively far. During the printing process, the printing material is prone to being uneven, affecting the printing quality and wasting printing materials.

[0004] (2) For double-sided printing, the distance between the two printing head groups needs to be shortened as much as possible to improve the printing quality. To shorten the distance as much as possible, the design and installation of the ink feeding and the material passing shafts in the printing route need to be reduced (the installation of the material passing shafts will increase the layout). However, the design of the material passing shafts is usually used to maintain or stabilize the ink feeding and the ink tension during the printing process. Reducing the installation of the material passing shafts will, to a certain extent, affect the stability during printing and instead reduce the printing quality. Therefore, how to consider both the layout and the printing stability factors when designing a double-sided spraying printer, avoid their mutual influence, and further improve the printing effect of the printer is a design difficulty for current double-sided spraying printers.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0042] As Figure 1As shown in the figure, this embodiment provides a high-precision double-sided spraying printer, which includes: a printing feeding component configured to convey printing materials to a printing component; the printing component includes a first printing device and a second printing device, and is configured to perform double-sided printing on the printing materials conveyed by the printing feeding component; wherein, the first printing device and the second printing device are configured to have a printing angle difference within a target angle range, the printing material output end of the first printing device is lower than the printing material input end of the second printing device, and a printing material tension stable area is formed between the printing material output end of the first printing device and the printing material input end of the second printing device; a first printing material tension stabilizing device 9 is arranged in the printing material tension stable area, and is configured to perform a first printing material turning action on the printing materials output from the printing material output end of the first printing device, perform a second printing material turning action on the printing materials input into the printing material input end of the second printing device, and perform a third printing material turning action on the printing materials output from the printing material output end of the second printing device; a printing output component configured to perform printing output on the printing materials output from the printing material output end of the second printing device.

[0043] It should be noted that currently, double-sided spraying printers usually adopt two ways of performing double-sided printing vertically or horizontally with two print head groups. In practical applications, there are the following technical defects: (1) When performing double-sided printing vertically or horizontally, a longer cloth path is required, and the distance between the two print head groups is relatively far. During the printing process, the printing material is prone to being uneven, affecting the printing quality and wasting printing materials; (2) For double-sided printing, it is usually necessary to shorten the distance between the two print head groups as much as possible to improve the printing quality. To shorten the distance as much as possible, it is necessary to reduce the design and installation of the material passing shafts in the printing material conveying and printing routes (the installation of the material passing shafts will increase the cloth path). However, the design of the material passing shafts is usually used to maintain or stabilize the printing material tension during the printing material conveying and printing process. Reducing the installation of the material passing shafts will, to a certain extent, affect the stability during printing and instead reduce the printing quality. Therefore, how to consider both the cloth path and the printing stability factors when designing a double-sided spraying printer, avoid their mutual influence, and further improve the printing effect of the printer is a design difficulty for current double-sided spraying printers.

[0044] To solve the above problems, in this embodiment, a first printing device and a second printing device with a printing angle difference within a target angle range are provided.

On the basis of shortening the cloth path, the tension stability of the ink during conveyance and double-sided printing can be improved, and the printing quality can be further enhanced.

[0045] In a preferred embodiment, the printing loading assembly specifically includes: a printing loading device 1 and a feeding cross bar 2.

[0046] In this embodiment, the ink is conveyed to the printing assembly through the printing loading device 1, the feeding cross bar 2, the feeding device 4, and the material pressing shaft to ensure the smooth input of the ink, which can improve the printing accuracy, speed, and color.
