Cleaning system for conveying mechanism of digital printer

Abstract

The invention discloses a cleaning system for a conveying mechanism of a digital printer. The cleaning system comprises a rack, a cleaning mechanism and a water supply system. The cleaning mechanism is located below a conveying belt. The cleaning mechanism comprises a cleaning disc, a first-stage brush roller, a front sponge roller, a rear sponge roller, a scraper plate, a front water spray pipe,a rear water spray pipe, a brush driving mechanism, an air knife and a water absorption roller, wherein the first-stage brush roller, the front sponge roller, the rear sponge roller, the scraper plate, the front water spray pipe, the rear water spray pipe, the brush driving mechanism, the air knife and the water absorption roller are sequentially arranged from front to back. The cleaning disc is arranged on the rack, can rise and fall and is of a trapezoidal structure. The water supply system comprises a circulating water tank, a water pump, a regulation valve, a dual filter screen and a liquid level meter. The cleaning system has the advantages that through a combined cleaning mode based on the first-stage brush roller used for removing fabric batting, the scraper plate used for scrapingwater and the sponge roller used for absorbing water, the cleaning effect is improved; little water is used, and little waste water is discharged and can be recovered and filtered to be used again, sothat energy saving and environmental friendliness are achieved; combined drying, cold air drying and multiple protection are adopted, so that the production efficiency is improved, and the rejectionrate is decreased; and the cleaning disk can rise and fall automatically and can slide out of a rack, so that maintenance is convenient.

Description

technical field [0001] The invention relates to a scanning digital printing machine, in particular to a cleaning system for the scanning digital printing machine. Background technique [0002] Scanning digital printing machines are widely used in clothing, cutting pieces, clothing, leather, luggage, transfer paper, artificial flowers, shoe materials, flocking cloth, thick plate, cloth, etc. The conveying mechanism of the scanning digital printing machine mainly includes a conveying belt, a driving roller, and a driven roller; when the conveying belt is working, because the cloth to be printed is pasted on the conveying belt; Rotate continuously, so that during the printing process, the printed ink and the fluff of the fabric will stick to the surface of the conveyor belt, which will cause the fabric behind to stick to ink, and the fluff will be watered if it cannot be cleaned; causing the back printing The fabric is watermarked, which makes the printed fabric unqualified. ...

Problems solved by technology

[0005] However, the above-mentioned invention also has the following disadvantages in the actual application process: (1) the combination of cleaning means is relatively simple, and the cleaning effect on the cloth lint sticking to the surface of the conveyor belt is not ideal; (2) the water consumption is large, and the waste water discharge is large , there is no waste water recycling system, which is not conducive to energy saving and environmental protection; (3) hot air drying, high temperature causes the conveyor belt to age too quickly, reduces the service life of the conveyor belt, and also increases energy consumption, which is not conducive to energy conservation and environmental protection; (4) The position of the cleaning and drying device is fixed, and maintenance is inconvenient
