5results about How to "Efficient printing" patented technology

The application discloses a laser printing method, a laser printer and a storage medium, and relates to the technical field of laser printing. The laser printing method comprises the following steps: performing gray scale conversion on a to-be-printed image to obtain a gray scale image; determining an initial laser energy value of each pixel point in the gray scale image; for each pixel point in the gray scale image, determining a laser energy compensation value of each pixel point in the gray scale image according to the initial laser energy value of each pixel point in a neighboring region; determining a target laser energy value of each pixel point in the gray scale image according to the laser energy compensation value and the initial laser energy value of each pixel point in the gray scale image; and printing the to-be-printed image according to the target laser energy value. The initial laser energy value of each pixel after the gray scale conversion of the to-be-printed image is compensated by the laser energy compensation value, the target laser energy value for printing is determined, and printing is performed, so that the image texture of an art sketch can be simulated during printing, and the image quality is ensured while high-efficiency printing is realized.

The utility model relates to the technical field of printing, and discloses an intelligent tipping paper printing device with an automatic adjusting function, which comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a supporting column, the outer wall of the supporting column is fixedly connected with a supporting plate, and the upper surface of the supporting plate is fixedly connected with a hydraulic machine. A first connecting block is fixedly connected to the output end of the hydraulic machine, a cutting blade is fixedly connected to the outer wall of the first connecting block, a second connecting block is fixedly connected to the outer wall of the cutting blade, a telescopic rod is fixedly connected to the outer wall of the second connecting block, and a spring is slidably connected to the outer wall of the telescopic rod. According to the paper cutting device, the hydraulic machine drives the cutting blade to move downwards through the first connecting block, then the telescopic rod drives the pressing plate to fix the tipping paper, at the moment, the telescopic rod shrinks and is compressed through the second connecting block and the spring, and at the moment, the cutting blade slides into the groove; and therefore, the effect of accurately cutting the tipping paper as required can be achieved.

The utility model discloses a printing mechanism which comprises a conveying structure, a rotating disc structure and a printing structure. The conveying structure is arranged on the peripheral side of the turntable structure; the printing structure is located above the rotary disc structure. Therefore, conveying and printing of the workpieces are conducted through rotation of the rotary disc structure, efficient printing can be achieved, meanwhile, flexible arrangement of the printing structure is facilitated, an operator can maintain the printing structure located on the periphery of the rotary disc structure conveniently, and therefore the maintenance cost and the maintenance difficulty are reduced.

The invention relates to a fabric conveying roller unit of a film type edible product manufacturing device. Namely, the fabric conveying roller unit of the film-type edible product manufacturing device guides the conveying of the fabric in a state of being arranged in the edible product manufacturing device for manufacturing the film-type edible product by enabling the fabric with a specified width continuously supplied from the outside to pass through and printing edible raw materials on the upper surface of the fabric, the fabric conveying roller unit of the film-type edible product manufacturing apparatus includes: a plurality of horizontal maintaining rollers that horizontally support a conveyed fabric; the suction roller is used for sucking the bottom surface of the fabric passing through the horizontal maintaining roller; a negative pressure supply unit that supplies negative pressure to the suction roller; and a roller driving portion that rotates the suction roller shaft so that the fabric receives the conveyance force from the suction roller under the action of the negative pressure. The fabric conveying roller unit of the film-type edible product manufacturing apparatus of the present invention, configured as above, stably maintains the conveying path of the continuously supplied fabric, enables good printing of edible raw materials, and prevents the printed edible raw materials from peeling off or being damaged during the conveying process of the fabric, thereby enabling production of edible products with uniform quality.
