Three-dimensional manual curve surface screen printing machine

Abstract

The invention relates to a three-dimensional manual curve surface screen printing machine which comprises a base plate, base plate supports and a space three-dimensional moving device. The base plate supports are disposed at four corners of the base plate. Lifting screws are disposed on the two base plate supports on the rear side. The space three-dimensional moving device is divided into an upper part and a lower part, the upper part is a liftable printing frame, and the lower part is a to-be-printed object three-dimensional moving mechanism. The lower mechanism is provided with a operation platform mounted on the base plate. Two slide rod station grooves are formed in the surface of the platform, four slidable longitudinal slide rods are mounted on the grooves, a transverses slide rod with a support bearing is mounted on each longitudinal slide rod, and the to-be-printed object is placed on the four support bearings. The upper printing frame is provided with an outer frame and a screen plate moving frame connected to the inside of the printing frame. A printing screen plate frame with a silk screen plate is connected into the screen plate moving frame. A scraper rack and a scraper are disposed on the screen plate moving frame. A balance iron square is disposed at the rear end of the outer frame. The printing machine is simple in structure, convenient to use, high in practicality and capable of printing cone frustums and cones with two ends of different diameters and irregular columns with handles.

Description

technical field [0001] The invention relates to a printing machine suitable for three-dimensional multi-angle curved surface printing, in particular to a three-dimensional manual curved surface screen printing machine with a spatial three-dimensional moving device, which belongs to the technical field of printing machines. Background technique [0002] At present, in most manual curved surface screen printing machines on the market, there are fixed tie rods around the machine to control and fix the whole body, and the rolling storage table and printing screen are placed within the range of the tie rods around the machine. If the substrate is a cone or a circular table with different upper and lower radii or even an object with a curved surface, the printing track of the printing surface will change in a curved line during the printing rotation process.

Problems solved by technology

If the substrate is a cone or a circular table with different upper and lower radii or even an object with a curved surface, the printing track of the printing surface will change in a curved line during the printing rotation process. With the pull of the scraper, the substrate will The two ends must support the screen due to the different radii, so that the printing surface of the substrate cannot be in contact with the screen in a large area, and the large-area contact cannot be guaranteed, and the screen cannot completely print the pattern. onto the substrate

In addition, when encountering a substrate with handles or protrusions in the shape, when the scraper is pulled, the protrusions will also be blocked by the screen frame body and the pull rod, which will also directly lead to the distortion of the screen pattern. destroy

Therefore, the problem of limited printing of such substrates is a big shortcoming of manual curved surface screen printing machines at present.

In addition, some of the existing screen printing machines have complex structures, high production and use costs, which also limit the popularization and application of this part of the screen printing machines.
