Description

Single-sided printing device for grid cloth

Technical field

The invention relates to a printing device, in particular to a grid cloth single-sided printing device.

Background technique

The mesh cloth is woven with medium alkali or alkali-free glass fiber yarn and coated with alkali-resistant polymer emulsion. Due to the special material characteristics of grid cloth, it is stronger and more durable than ordinary cloth because of its high strength and good alkali resistance. The application of the grid is more linked to the advertising industry, and the places involved are basically used for advertising on the walls of high-rise buildings. Therefore, it is often necessary to print some fonts, graphics or logos on the fabricated grid. In the past, the finished grid cloth was taken out separately for inkjet printing and other printing, which was extremely inefficient. Nowadays, grid cloth can be printed when the grid cloth is made to complete the winding, but there are still many defects: It is necessary to start a separate set of devices dedicated to printing, and the printing effect is not good, and it is impossible to evenly print an appropriate amount of ink on the grid cloth.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The accompanying drawing shows a specific embodiment of the present invention. This embodiment includes a grid cloth roller 1 wound with a grid cloth. The grid cloth roller 1 is installed on the machine body 2. A printing stencil roller 3 is provided under the grid cloth roller 1 and an inking roller 4 is provided under the printing stencil roller 3 , There is an ink cartridge 5 under the ink application roller 4, a scraper 6 is provided on the side of the ink application roller 4, the bearings at both ends of the grid cloth roller 1 are installed in the lifting block 7, the lifting block 7 is clamped on the inner side of the slide rail 8, the lifting block 7 The top is connected with the lifting screw 9. The right end of the mesh roller 1 is driven by a power chain 10, a tension pendulum rod 11 is arranged on the outer side of the power chain 10, and a tension spring 12 is connected to the bottom of the tension pendulum rod 11. Both ends of the ink roller 4 and the scraper 6 are mounted on the slider 13. The slider 13 can move along the track 14 mounted on the body 2. The track 14 is equipped with a moving screw 15 which is opposite to the rear end of the slider 13 connect. A handle 16 is installed on the moving screw 15. A steering gear 17 is installed at the end of the scraper 6, the steering gear 17 is meshed with the power screw 18, the power screw 18 is integrally installed with the power shaft 19, and the power shaft 19 is installed on the slider 13. The grid cloth roller 1, the printing template roller 3 and the ink application roller 4 are equipped with power gears 20 meshing with each other on the left side.

Using a single-sided printing device for grid cloth of the present invention, the printing template roller 3 is fixedly installed on the body 2. When printing on the grid cloth is required, first loosen the tension spring 12 connected to the body 2 and rotate it two clockwise. The lifting screw 9 on the side can push the lifting block 7 down along the slide rail 8, and then bring the grid

The cloth roller 1 is lowered to a suitable position, so that the power gear 20 of the grid cloth roller 1 is meshed with the power gear 20 of the printing template roller 3, and then the tension spring 12 is tightened, so that the tension pendulum 11 will tighten the power chain 10 and stretch it. The top of the tight swing rod 11 is hinged on the body 2. The outer side of the lifting block 7 and the inner side of the sliding rail 8 are matched with protrusions and grooves to prevent misalignment. Then, hold the handle 16, turn the screw 15 clockwise, and move the screw 15 forward. Then the slider 13 will be pushed along the track 14 to make the ink application roller 4 reach the proper position. At this time, the power of the printing template roller 3 The gear 20 will mesh with the power gear 20 on the ink applicator roller 4. After releasing the hand, due to the action of the moving screw 15, the slider 13 will be relatively fixed to the track 14. Then, the power shaft 19 is rotated, and then the power screw 18 drives the steering gear 17 to rotate, so that the doctor blade 6 slowly approaches the ink application roller 4 to a suitable position. After starting, the power chain 10 grid cloth roller 1 rotates, and then the printing stencil roller 3 and the inking roller 4 are driven to rotate through the power gear 20 in turn. The inking roller 4 rotates in the ink cartridge 5 to stick the ink to the inking roller 4 The ink application roller 4 will be evenly scraped by the scraper 6 during the rotation process, and then the ink will be brought to the pattern text template of the printing stencil roller 3, and the ink on the pattern text template of the printing stencil roller 3 will stick to the screen. On the grid cloth of the grid cloth roller 1, the grid cloth is printed. When printing is not required, just lift up the grid cloth roller 1.
