A special printing tool for bent tempered glass

Abstract

The present invention discloses a special printing tool for bent tempered glass, and the present invention relates to the technical field of glass printing. For this special printing tool for bent tempered glass, through the arrangement between the limiting component and the shaping component, when the device processes bent tempered glass, the arc of the printing tool holder and the printing tool blade can be adjusted, and through the cooperation of a number of inner connecting rods, limiting sleeves, stop wheels and other components, the printing tool holder can be positioned to maintain this arc for printing operations on the bent tempered glass. Compared with traditional manual adjustment methods, the arc of the tool blade is more uniform, and it is convenient to adjust the arcs of the printing tool holder and the printing tool blade according to the different arcs of the bent tempered glass. By making the printing tool holder and the printing tool blade maintain the same arc as the bent tempered glass, the pressure on the ink can be consistent when the device prints the glass, ultimately ensuring the uniformity of the ink layer of the ink film, and at the same time improving the adjustment convenience and application range of the device.

Description

Technical Field

[0001] The present invention relates to the technical field of glass printing, and particularly to a special printing tool for bent tempered glass. Background Art

[0002] The printing of colored crystal glass is generally divided into flat tempered glass printing and bent tempered glass printing. The flat tempered glass is flat, and the blade skin of the printing tool is also flat, so that the blade skin and the glass can be kept consistent, and the thickness of the printed ink layer can be made uniform. Since the bent tempered glass is a curved glass, the blade skin of the printing tool mostly needs to be adjusted manually to make the curvature of the blade skin consistent with the glass. However, the consistency of manually adjusting the R curvature of the blade skin is not good, with uneven convex and concave surfaces, resulting in inconsistent thickness of the printed ink layer, forming color difference, and reducing the printing effect of the tool.

A plurality of sliders are provided on both sides of the limit sliding plate 201, and the limit sliding plate 201 is slidably arranged inside the printing tool holder 2 through the sliders. The limit ends 3 on both sides are symmetrical to each other;

[0032] In the embodiment of the present invention, the shaping component includes a limiting ear 5. There are several limiting ears 5, which are respectively fixedly installed on both sides of the top surface of the printing tool rest 2. An inner connecting rod 6 is rotatably installed inside each corresponding limiting ear 5. The other ends of several inner connecting rods 6 are all slidably sleeved with a limiting sleeve 7. Both sides of several limiting sleeves 7 are fixedly installed with a rotating shaft 701, and are respectively rotatably installed inside the limiting frame 1 through the cooperation of the corresponding rotating shaft 701. The ends of the rotating shafts 701 on one side are all fixedly installed with a stop wheel 702. The shaping component further includes a stop airbag 9. The bottom of the stop airbag 9 is fixedly installed with a positioning arc plate 901, and is fixedly installed on the outside of the limiting frame 1 through the cooperation of the positioning arc plate 901.

[0034] During use, through the setting of the limiting component and the shaping component, first, the limiting frame 1 is assembled to the printing equipment through the positioning ear 101. When printing, first place the bent tempered glass to be printed and fix it at the bottom of the printing tool rest 2. When printing, first perform the arc shaping operation. By the downward movement of the limiting frame 1, the printing tool rest 2 at the bottom can be driven to move downward and contact the arc surface of the bent tempered glass. As the limiting frame 1 continues to press down, the printing tool rest 2 is deformed under pressure. As the arc of the printing tool rest 2 increases, while the two ends rotate with the corresponding limiting ends 3, the two side limiting ends 3 can be pulled inward, so that while sliding inward through the sliding rod 301, the corresponding support springs 302 are compressed until the printing tool rest 2 is completely in contact with the arc surface of the bent tempered glass under pressure, and then the arc adjustment can be completed;

[0035] In the embodiment of the present invention, through the setting of the shaping component, when the printing tool holder 2 is adjusted in terms of its radian, as its radian increases, it retracts into the inside of the limit frame 1, and the inner connecting rod 6 connected by rotation can be jacked up by the corresponding limit ear 5. While the end of the inner connecting rod 6 slides inside the limit sleeve 7, the limit sleeve 7 rotates inside the limit frame 1 through the cooperation of the rotating shaft 701 until the limit sleeve 7 stops rotating after the radian adjustment of the printing tool holder 2 is completed. At this time, the air pump 8 operates to fill the stop airbag 9 with gas. While it expands, it pushes the outer stop piece 902 outwards until it fits with a plurality of stop wheels 702 to complete the limitation of the stop wheels 702, and then the radian shaping operation of the printing tool holder 2 can be completed;

[0036] In the embodiment of the present invention, when the printing tool holder 2 is pressed down for radian adjustment, the limit sliding plate 201 and the printing blade 202 at its bottom can be compressed and retracted into the printing tool holder 2 as they come into contact with the bent tempered glass, and then as the printing tool holder 2 deforms until its shape is the same as that of the printing tool holder 2. After the radian shaping operation of the printing tool holder 2 is completed, by moving the limit frame 1 upwards, the limit sliding plate 201 and the printing blade 202 inside it can be pushed out by the return spring 203, and then move downwards until the printing blade 202 contacts the surface of the bent tempered glass, and then the printing operation can be carried out;

[0037] Through the setting of the cleaning component, when the limit frame 1 operates to drive the printing tool holder 2 and the printing blade 202 at the bottom to translate for printing the bent tempered glass, the cleaning scraper 402 and the cleaning cotton strip 403 fixedly installed at the bottom of the cleaning frame 4 can contact the surface of the bent tempered glass. By first cleaning and wiping its surface, the printing effect of the subsequent printing blade 202 can be effectively guaranteed.
