A modern printing machine is generally composed of plate mounting, ink application, impression, paper feeding (including folding) and other mechanisms. Its working principle is: first, the characters and images to be printed are made into printing plates, which are mounted on the printing machine, then the ink is applied to the places with characters and images on the printing plate by manual or printing machine, and then transferred to paper or other printing materials (such as textiles, metal plates, plastics, leather, wood, glass and ceramics) directly or indirectly, thus copying the same printing plate to produce the same printing product. According to the form of printing plate, it is divided into relief, lithographic, intaglio and hole plate printing machines; according to the installation and impression structure, it is divided into flat-plate, round-plate and round-round printing machines.

[0003] The existing screen printing machine needs to be operated by two people, one end is responsible for feeding, and the other end is responsible for discharging. When the material passes through the middle, the scraper lifting mechanism drives the scraper and the screen to move downward to contact with the material, and then the scraper transmission mechanism drives the scraper to move left and right to complete printing. After printing, the scraper is reset, and the material flows to the discharging position for discharging. This method is high in labor cost and low in production efficiency. In addition, the cleaning of the screen needs to be disassembled for operation, which is troublesome and greatly affects the operation of the equipment. SUMMARY

[0019] In order to make the purpose, technical scheme and advantages of the present utility model more clear and obvious, the present utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0020] In order to illustrate the technical scheme of the present utility model, the following will be described through specific embodiments.

[0021] EMBODIMENT

[0022] Please refer to Figures 1 to 3 The present embodiment provides a three-dimensional hard ceramic unit surface metallization equipment, which comprises a rack 1, a working platform 2 arranged on the rack 1, a first linear guide rail 3 arranged on the working platform 2, a printing table driving mechanism 4, a printing table 5 and a screen printing device 6.

[0023] Among them:

[0024] The first linear guide rail 3 is provided with two positioning blocks 7 at two ends, and the two first linear guide rails 3 are divided into an upper and lower material loading and unloading station and a printing station. The printing table 5 is movably connected to the two first linear guide rails 3 through the electric cylinder lifting assembly 8 and reciprocally moves between the material loading and unloading station and the printing station under the driving action of the printing table transmission mechanism 4. The cleaning doctor 9 is provided on the side of the printing table 5 facing the printing station and is perpendicular to the moving direction of the printing table 5. The cleaning doctor 9 is provided with a cleaning doctor lifting mechanism 10 at the bottom.

[0025] The screen printing device 6 is located above the printing station of the two first linear guide rails 3. The screen printing device 6 comprises a bracket 61, a box body 62 provided on the bracket 61, a second linear guide rail 63 provided in the box body 62, a printing doctor transmission mechanism 64, a printing doctor lifting mechanism 65, a printing doctor 66, and a screen mounting jig 66 provided at the bottom of the box body 62. The box body 62 is provided with an opening cover 67 pivotally arranged thereon. The second linear guide rail 63 is provided with two parallel first linear guide rails 3. The printing doctor 66 is movably connected to the two second linear guide rails 63 through the printing doctor lifting mechanism 65 and reciprocally moves along the second linear guide rail 63 under the driving action of the printing doctor transmission mechanism 64. The screen mounting jig 66 is arranged around the moving range of the printing doctor 66 and is located above the two first linear guide rails 3. The screen mounting jig 66 is provided with a cylinder locking device 68 on the opposite sides. The screen is mounted at the bottom of the screen mounting jig 66 and is fixed by the cylinder locking devices 68 on the two sides.

[0026] The device integrates the material loading and unloading stations in one station. Only one person is needed to operate the device, which reduces labor costs compared with the existing two-person operation.

[0027] The printing table of the device is provided with a lifting function, and the screen is in a fixed position. When printing, the electric cylinder lifting assembly 8 at the bottom of the printing table 5 drives the printing table 5 to move upward to contact the screen. At the same time, the printing doctor 66 above descends and reciprocally moves left and right under the driving action of the printing doctor transmission mechanism 64 to print on the surface of the hard ceramic. After printing is completed, the printing table 5 and the printing doctor 66 are reset, respectively, and the printing table 5 returns to the material loading and unloading station for unloading. This working mode is more efficient than the existing mode in which the doctor lifting mechanism drives the doctor and the screen to move downward together.

[0028] The device is provided with the cleaning doctor 9 which is perpendicular to the moving direction of the printing table 5 on the side of the printing table 5 which faces the printing station and is upward, and the cleaning doctor lifting mechanism 10 at the bottom of the cleaning doctor 9 can drive the cleaning doctor 9 to rise and contact the screen when the printing table 5 returns to the feeding and discharging station after each printing is completed, so that the surface of the screen is cleaned during the returning process of the printing table 5, and the cleaning mode does not need to stop for cleaning, the operation is simpler relative to the existing cleaning mode of disassembling the screen, and the normal operation of the device is not affected.

[0029] The above is only the preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application should be included in the protection scope of the present application.
