Description
Technical Field
The utility model relates to a printing machine, concretely relates to knitted fabric printing machine.
Background
The knit printer is used to print a desired pattern on a knit fabric blank (e.g., a knitted wool blank, a sweater-forming blank). The printing mechanism of the knitted fabric printing machine generally comprises a cloth supporting plate, a printing template, a scraper and a scraper translation mechanism capable of driving the scraper to translate in a reciprocating manner, wherein the printing template is arranged above the cloth supporting plate, and the scraper is arranged above the printing template. When a knitted fabric printer is used for printing on knitted fabric gray fabric, the knitted fabric gray fabric is firstly flattened and fixed on the upper surface of a fabric support plate (the knitted fabric gray fabric can be fixed on the upper surface of the fabric support plate through pasting or other modes), then the fabric support plate and the knitted fabric gray fabric are placed on the knitted fabric printer, the printing is finished by a printing mechanism after the fabric support plate is positioned, and then the fabric support plate and the printed knitted fabric gray fabric are manually dismounted. The printing mechanism is typically a screen printing mechanism in which the printing stencil employs a screen printing plate.
Most of the traditional knitted fabric printers are provided with one printing mechanism, each knitted fabric printer can print patterns or color blocks with one color on the grey fabric of the knitted fabric, and the patterns or the color blocks with various colors jointly form the required printed patterns after the patterns or the color blocks are combined and overprinted by a plurality of knitted fabric printers. Because each knitted fabric printing machine needs to be configured with workers to carry out loading, unloading and other work, and needs to move the cloth supporting plate unloaded from the previous knitted fabric printing machine and the knitted fabric grey cloth on the cloth supporting plate to the next knitted fabric printing machine, when multicolor overprinting is needed, the work of loading, unloading and moving needs to be carried out for many times, the workload is large, a large number of workers need to be configured, and the labor cost is high.
In order to realize multicolor overprinting on a printing machine, save manpower, reduce labor cost and save occupied area of the machine, the prior utility model patent of the applicant (the patent number is CN201821208983.8, and the publication number is CN 208682311U) provides a wool printing machine, which comprises a frame and a feeding mechanism; the feeding mechanism comprises a cloth supporting plate conveying frame and a cloth supporting plate conveying frame translation mechanism capable of driving the cloth supporting plate conveying frame to reciprocate back and forth, and the cloth supporting plate conveying frame translation mechanism is installed on the rack; the feeding mechanism is sequentially provided with a feeding station, a plurality of printing stations and an unloading station from front to back along the feeding direction, each printing station is respectively provided with a cloth supporting plate lifting mechanism, each cloth supporting plate lifting mechanism comprises a cloth supporting plate supporting table and a cloth supporting plate supporting table lifting mechanism capable of driving the cloth supporting plate supporting table to lift, and the cloth supporting plate supporting table lifting mechanism is arranged on the rack; each printing station is provided with a printing mechanism. When a wool printing machine is used for printing wool grey cloth (belonging to knitted fabric grey cloth), firstly, the wool grey cloth is flattened and fixed on the upper surface of a cloth supporting plate (the wool grey cloth can be fixed on the upper surface of the cloth supporting plate in a sticking or other mode), and then the cloth supporting plate and the wool grey cloth are placed on the front part of a cloth supporting plate conveying frame, which corresponds to a feeding station; and then the cloth supporting plate conveying frame translation mechanism drives the cloth supporting plate conveying frame to integrally move forward to a station, the cloth supporting plate on the front part of the cloth supporting plate conveying frame and wool grey cloth reach a first printing station, the cloth supporting plate on the first printing station and the wool grey cloth reach a second printing station, and by analogy, the cloth supporting plate on the last printing station and the wool grey cloth reach an unloading station. Manually taking down the cloth supporting plate and the printed wool grey cloth from the rear part of the cloth supporting plate conveying frame at an unloading station; after the cloth supporting plate on the unloading station and the printed wool grey cloth are moved away, the cloth supporting plate conveying frame can be moved back to move in a translation mode to reset. The cloth supporting plate conveying frame is driven by the cloth supporting plate conveying frame translation mechanism to reciprocate back and forth, the cloth supporting plate and wool grey cloth move forward by one station every time the cloth supporting plate is translated backward, then the cloth supporting plate is translated back and reset to be ready for receiving and conveying the next cloth supporting plate, and therefore the cloth supporting plate and the wool grey cloth are sequentially conveyed to each printing station by the feeding mechanism, and after printing is sequentially completed by each printing mechanism, the cloth supporting plate and the wool grey cloth are conveyed to the unloading station to be unloaded.
Although the wool printing machine can realize multicolor overprinting, the printing templates in each printing mechanism adopt the screen printing plate, the silk screen printing machine belongs to the screen printing mechanism, the screen printing mode is adopted to print patterns or color blocks with larger areas, and some knitted fabric gray fabrics need to be printed with more complicated and fine pictures and texts (such as characters with small strokes), which are limited by the screen mesh thickness degree of the printing templates, if the wool printing machine is adopted to print, the pictures and texts are more fuzzy, and the product quality is poor.
