Description

Novel ink scraper

Technical Field

The utility model relates to a novel printing ink scraper.

Background

Conventional doctor blades are less wear resistant under normal use conditions of the printing machine, and the cross-sectional area of the contact surface of the doctor blade with the screen increases continuously as the doctor blade wears, which is very detrimental to the wiping and causes a change in the value of the image tone after printing, in which case the life of the doctor blade is very short. In addition, in the printing process, ink needs to be added continuously, which wastes time and labor, thereby affecting the printing quality of products and being very troublesome and fussy.

Disclosure of Invention

For overcoming the defects of the prior art, the utility model provides a novel printing ink scraper, the technical scheme of the utility model is that:

the novel ink scraper comprises a scraper main body, an ink box, a roller and a handle, wherein the section of the scraper main body is arranged in a V shape, a groove for accommodating the handle is formed in the scraper main body, the handle is rotatably arranged in the groove through a pin shaft, and an included angle is formed between the side surface of the handle and the scraper main body; the two sides of the outer part of the scraper main body are respectively provided with an ink box, the bottom of each ink box is rotatably provided with a roller, the bottom of the scraper main body extends downwards between the two rollers to form a bottom edge of the scraper, more than half of the volume of each roller is embedded into an ink outlet of the ink box, the rest part of each roller is positioned outside the ink outlet, and the rollers are movably matched with the ink outlets of the ink boxes.

When the handle is placed along the vertical direction, the included angle between the side surface of the handle and the scraper main body is 5 degrees.

The utility model has the advantages that:

1. the printing and dyeing process can be realized by reciprocating motion, and the printing efficiency is doubled compared with the traditional unidirectional printing efficiency.

2. The ink output quantity is output in direct proportion to the printing speed and the roller rotating speed, so that the uniform ink output and the uniform printing and dyeing coloring are ensured.

3. Form the printing ink collection between arris, ink horn, roller and the printing and dyeing version at the bottom of the scraper and deposit the district, the printing ink secondary that the arris was deposited the district with the printing ink collection in the printing and dyeing version mesh is impressed at the bottom of the scraper can avoid appearing the printing product phenomenon of lacking in ink, avoids the wastrel to appear.

Detailed Description

The invention will be further described with reference to specific embodiments, the advantages and features of the invention will become more apparent as the description proceeds. These examples are merely illustrative and do not limit the scope of the invention in any way. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention, and that such changes and modifications are intended to be included within the scope of the invention.

Referring to fig. 1 to 4, the utility model relates to a novel ink scraper, which comprises a scraper main body 3, an ink box 2, a roller 1 and a handle 5, wherein the section of the scraper main body 3 is arranged in a V shape, a groove for accommodating the handle is arranged inside the scraper main body, the handle 5 is rotatably arranged in the groove through a pin shaft 4, and an included angle is formed between the side surface of the handle 5 and the scraper main body 3; the two sides of the outer part of the scraper main body 3 are respectively provided with an ink box 2, the bottom of each ink box 2 is rotatably provided with a roller 1, the bottom of the scraper main body 3 extends downwards between the two rollers 1 to form a scraper bottom edge, more than half of the volume of each roller 1 is embedded into an ink outlet 8 of the ink box, the rest part of each roller is positioned outside the ink outlet 8, and the rollers 1 are movably matched with the ink outlets 8 of the ink boxes.

When the handle 5 is placed along the vertical direction, the included angle between the side surface of the handle 5 and the scraper main body 3 is 5 degrees.

The utility model discloses a theory of operation is: when the scraper main body works and moves towards the right side, the scraper main body rotates clockwise by 5 degrees around the pin shaft and clings to the handle, meanwhile, the roller at the bottom of the right ink box is contacted with the screen printing plate 7, under the action of pressure, the right roller deflects to one side of the ink outlet at the bottom of the ink box while rotating, a gap is generated between the right roller and the right roller of the ink box, ink in the ink box flows out from the ink box 2 at a constant speed along with the rotation of the roller 1, simultaneously, the roller 1 on the right side presses printing ink to the mesh on the screen printing plate 7, and meanwhile, an ink collecting and storing area 6 is formed between the scraper bottom edge of the scraper main body bottom, the bottom of the ink box, the roller and the screen printing plate, and the printing ink in the ink collecting and storing area is pressed into the mesh on the screen printing plate by the scraper bottom edge in the advancing process, so that the phenomenon of ink shortage can be avoided. When the scraper runs to the edge of the screen printing plate, the handle 5 is directly held by hand to drive the scraper to move leftwards in a reverse direction, the scraper body 3 rotates anticlockwise for 10 degrees around the pin shaft 4, then the left ink box and the roller start to work, and the printing is completed by circularly reciprocating the processes; the ink boxes 2 on the left side and the right side of the scraper only have the working ink box to discharge ink, the ink box on the non-working side does not discharge ink, and the roller realizes the sealing of the ink outlet under the action of self gravity.
