Printing device

Abstract

The utility model relates to the technical field of printing devices, and discloses a printing device which comprises a machine frame and roller frames fixed on the machine frame, a smearing roller, a printing roller and a clamping compression roller are arranged between the roller frames in a rotating mode, and a dye disc containing dye is further fixed on the machine frame. The lower side of the smearing roller makes contact with dye in the dye disc and makes contact with the printing roller in a rotating and attaching mode at the same time, a protruding floral pattern structure is arranged on the surface of the printing roller and used for pressing the smeared colored dye on fabric, and in addition, symmetrical sliding plates are fixedly arranged in the roller frame. Due to the fact that the embossing position is located above the embossing roller, the phenomenon that dye drips in a concentrated mode is avoided, the thickness of the sponge liquid absorption sleeve is smaller than that of the embossing protruding structures, hydrophobic paint is sprayed on the side walls of the embossing protruding structures, redundant dye drips downwards under the action of gravity in the rolling process of the embossing roller, and the embossing effect is improved. The patterns cannot be printed on the fabric, so that the clearness of the patterns is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of printing devices, in particular to a printing device. Background Art

[0002] The existing Chinese patent publication number is (CN218857946U), which discloses a printing device, including a base frame, a gantry frame and a structural frame, wherein the base frame has a No. 2 transmission roller installed at equal distances through bearings, and the base frame has a No. 1 transmission roller installed at one end through bearings, and the No. 1 transmission roller and the No. 2 transmission roller are sleeved with a conveyor belt on the outside, and the top of the base frame is fixed with a gantry frame by bolts, and the top of the gantry frame is welded with an internal threaded sleeve, and a screw is inserted through the internal threaded sleeve, and the bottom end of the screw is installed with a structural frame through a bearing, and a printing roller is installed inside the structural frame through bearings, and the top of the structural frame is fixed with a structural frame by bolts, and a liquid collecting pipe is installed on the top of the structural frame through a mounting frame. The utility model can not only emboss the surface of the packaging material by means of a printing roller, but also color the embossed pattern when necessary;

[0003] However, the printing position of the above patent structure is located at the bottom, while the position for supplementing the dye is located at the top, which causes the dye to drip downward under the action of gravity, causing excess dye to drip onto the fabric and affect the printing quality. In addition, it has no drying mechanism, so that the printing dye cannot be cured in time, causing the dye to blur and the printing to be unclear. In addition, the figure marks in the patent document and the marks in the drawings of its specification do not match at all, and technicians in this field are completely unclear about how to implement it. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above problems, a printing device is provided, which solves the above problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A printing device comprises a frame and a roller frame fixed on the frame, between which a coating roller, a printing roller and a clamping roller are rotatably arranged;

[0007] The frame is also fixedly provided with a dye tray containing dye, and the lower side of the smear roller is in contact with the dye in the dye tray and is simultaneously in rotational contact with the printing roller, a raised pattern structure is provided on the surface of the printing roller for pressing the applied colored dye onto the fabric, and in addition, a symmetrical slide plate is fixedly provided in the rotating roller frame, a bearing sliding seat is provided between the slide plates for sliding up and down, the clamping roller is rotatably arranged in the bearing sliding seat, and an electric push rod is also fixedly provided on the rotating roller frame for driving the bearing sliding seat to move up and down, the clamping roller is lifted before loading the cloth so that the cloth passes between the printing roller and the clamping roller, and then the clamping roller is pressed down to press the cloth tightly onto the printing roller, when the cloth moves, the printing roller and the clamping roller roll, and at the same time, the printing roller drives the smearing roller to roll in a cycle, the smearing roller absorbs the dye in the dye tray and smears it on the raised printing surface of the printing roller to print the fabric.

[0008] Preferably, the smearing roller comprises a metal inner cylinder and a sponge liquid absorbing sleeve sleeved outside the metal inner cylinder for absorbing the dye and smearing it on the outer surface of the printing roller, and the wall thickness of the sponge liquid absorbing sleeve is one centimeter.

[0009] Preferably, the convex thickness of the convex printing pattern on the surface of the printing roller is at least three times the wall thickness of the sponge absorbent sleeve, so that when the printing roller and the smear roller contact each other, the dye can be completely applied to the surface of the printing pattern and will not remain too much in the gaps of the printing pattern. In addition, in addition to the convex surface of the printing pattern, the outer surface of the printing roller is sprayed with a hydrophobic coating to avoid retaining dye.

[0010] Preferably, an air drying box is fixed on the frame by bolts, and the cloth passes under the air drying box after printing. Thermal radiation lamps are fixed at intervals on the top of the air drying box for curing the dye.

[0011] Preferably, a plurality of fans are fixedly provided on the air drying box for quickly exhausting water vapor during the drying and curing process.

[0012] Preferably, a cloth guiding frame is provided in front of the frame for guiding the cloth to prevent it from contacting the dye tray.

[0013] The advantages and positive effects of the utility model are:

[0014] 1. Since the embossing position is located above the printing roller, there will be no concentrated dripping of dye. In addition, since the thickness of the sponge absorbent sleeve is smaller than the printing raised structure, and the side wall of the printing raised structure is sprayed with a hydrophobic coating, the excess dye of the printing roller will drip downward under the action of gravity during the rolling process, and will not be printed on the fabric at all, thereby ensuring the clarity of the pattern.

[0015] 2. The coating roller is in full contact with the dye, ensuring that the dye is evenly absorbed.

[0016] 3. Dry the print immediately after printing is completed to solidify the pattern, avoid dye blurring, and ensure printing quality. BRIEF DESCRIPTION OF THE DRAWINGS
