Description

Technical Field

[0001] The utility model relates to the technical field of printing, and more specifically, to an automatic screen printing machine. Background Art

[0002] Screen printing is a printing method. The screen plate is designed with hollow holes. The ink passes through the screen plate through the hollow holes and adheres to the substrate to achieve printing. The printed pattern is related to the position of the hollow holes.

[0003] When screen printing is in progress, a scraper is used to scrape the screen plate, on which ink is attached. The pressure exerted by the scraping on the ink allows the ink to pass through the hollow holes.

[0004] If the ink is exposed to the air for a long time, it will easily cause the ink to deteriorate. At the same time, too much ink will affect the scraping of the scraper. Therefore, do not add too much ink on the screen. When the ink is reduced, ink needs to be added to the screen.

[0005] However, this increases the frequency of addition and reduces processing efficiency.

[0006] This application provides another technical solution to this technical problem. Utility Model Content

[0007] In view of the deficiencies in the prior art, the utility model aims to provide an automatic screen printing machine.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0010] The utility model is further configured as follows: the middle part of the bracket is rotatably connected to the machine base through a rotating shaft, and the printing head and the driving component are respectively located at two ends of the bracket that are far away from each other.

[0011] The utility model is further configured as follows: the driving member comprises a motor mounted on a machine base, a connecting rod is arranged between the motor and the bracket, an eccentric plate is installed on the motor, and two ends of the connecting rod are rotatably connected to the bracket and the eccentric plate respectively.

[0012] The utility model is further configured as follows: the height of the ink storage bottle is always higher than the ink filling head, the channel in the ink filling head includes a flat section and a contraction section, the shielding member includes a steel ball, the steel ball abuts against the side wall of the contraction section, and the ink filling head is formed with an ink outlet corresponding to the flat section.

[0013] The utility model is further configured as follows: the cross section of the flattened section is consistent with the cross section of the steel ball, and the diameter of the steel ball is smaller than the diameter of the flattened section.

[0014] The utility model is further configured as follows: a magnetic rubber for contacting with the steel ball is fixedly connected to the contraction section, and the magnetic rubber and the steel ball attract each other.

[0015] In summary, the utility model has the following beneficial effects:

[0016] When printing is in progress, the clamp block is parallel to the substrate, and the ink adding head is inclined. The steel ball will overcome the suction of the magnetic rubber due to gravity, and the obstruction to the ink adding head will be released. The ink in the ink storage bottle will flow to the ink adding head to achieve ink adding. When printing is not in progress, the clamp block is parallel to the substrate, and the inclination direction of the ink adding head changes. The steel ball will contact the magnetic rubber due to gravity, and the magnetic force of the magnetic rubber will keep the ink adding head blocked, and the ink adding is closed. In this way, ink can be automatically added every time printing is performed, which improves the convenience of operators and improves printing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] When printing, the substrate is laid flat on the machine base 1, ink is added to the screen plate, and the scraper is used to apply the ink to the screen plate by utilizing the electric slide rail 6 and the cylinder. Then, the motor 3 is energized, the bracket 2 rotates, and the screen plate rotates toward the substrate until the screen plate and the machine base 1 squeeze the substrate. The electric slide rail 6 and the cylinder are activated again, and the scraper is used to scrape the ink, thereby printing the substrate.

[0025] like Figure 1 and Figure 3 As shown, the bracket 2 is installed with an ink storage bottle 9 and an ink filling head 10, and the ink storage bottle 9 and the ink filling head 10 are connected by an oil pipe 16, and the height of the ink storage bottle 9 is always higher than the ink filling head 10. By utilizing the height difference, the ink in the ink storage bottle 9 will flow into the ink filling head 10 through the oil pipe 16, and then flow into the screen plate through the ink filling head 10, thereby realizing the replenishment of the ink on the screen plate.

[0026] like Figure 1 and Figure 4As shown, the channel in the ink filling head 10 includes a flat section 12 and a contraction section 11.
