When the width of the screen printing plate 201 is larger, the clamping mechanisms 21 on the two sides of the screen printing plate 201 can be moved to the position ahead of the longitudinal rod 2051; when the width of the screen printing plate 201 is smaller, the clamping mechanism 21 can be moved to the position behind the longitudinal rod 2051, so that the mounted screen printing plate 201 always has good balance stability.
More specifically, when the screen printing plate 201 is installed, the bottom of the frame of the screen printing plate 201 is located on the lower clamping plates 212 of the clamping mechanisms 21 on both sides; then, the worker pushes the fixing rod 215 downward to press the lower end of the fixing rod 215 against the top of the screen frame, thereby completing the installation of the screen printing plate 201.
Further, a second guide rod 24 parallel to the cross rod 2052 is fixedly arranged above the cross rod 2052; the second guide rod 24 is movably connected with two moving mechanisms 25 respectively connected with the two longitudinal rods 2051; the moving mechanism 25 comprises a connecting handle 251 movably sleeved on the second guide rod 24, a second guide plate 252 connected with the connecting handle 251, and a connecting block 253 movably connected with the second guide plate 252; the connecting block 253 is connected with the vertical rod 2051. More specifically, the connecting block 253 is provided with a fourth sliding block 26, and the second guide plate 252 is vertically provided with a third guide groove 27 matched with the fourth sliding block 26.
When installing the screen printing plate 201, an operator can move the connecting handle 251 to adjust the position of the moving mechanism 25 after the connecting handle 251 moves along the second guide rod 24, so as to meet the installation requirements of the screen printing plates 201 with different lengths. In addition, during actual installation, the fourth slider 26 can drive the connecting block 253 to move up and down along the second guide plate 252, so that the height of the vertical frame and the height of the screen printing screen 201 can be adjusted, and different printing operation requirements can be met.
Referring to fig. 1, fig. 2 and fig. 4, in another embodiment, a suspension column 28 is disposed above the machine platform 1, and the suspension column 28 is connected to an installation platform 29 for installing a plurality of first hydraulic devices 203; the first scraper 202 is disposed below the mounting platform 29 and is connected to a first hydraulic device 203. When a printing operation is performed on a ceramic pipe to be printed, the first scraper 202 is pushed downward by the first hydraulic device 203 to be pressed against the ceramic pipe.
Referring to fig. 2 and 4, in another embodiment, the screen printing apparatus 2 further includes a second squeegee 30 disposed parallel to the first squeegee 202; the second scraper 30 is arranged at the rear side of the first scraper 202, and the top of the second scraper 30 is connected with a third hydraulic device 31. In this embodiment, the third hydraulic device 31 is identical to the first hydraulic device 203 and the second hydraulic device 301, and may be a device for lifting or lowering an object, such as a cylinder or a jack.
During the actual printing operation, the first squeegee 202 and the ceramic pipe are kept pressed against each other. Since the screen plate 201 moves forward during printing, the heating resistor paste not printed on the screen is pushed to the rear end of the screen by the first squeegee 202. In this embodiment, when the ceramic tube is printed and the screen printing plate 201 moves backward, the second scraper 30 is pushed downward to contact with the upper surface of the screen under the action of the third hydraulic device 31, and the first scraper 202 is lifted upward by the first hydraulic device 203, so that the second scraper 30 can push the unprinted thermal resistance paste back to the lower side of the first scraper 202 during the backward movement of the screen printing plate 201, and it is ensured that enough thermal resistance paste is printed on the ceramic tube by the first scraper 202 during the printing operation.
Referring to fig. 1, in another embodiment, the heating resistor paste printing apparatus further includes a control device 32 disposed on the front side of the machine 1; the processing unit is arranged in the control device 32; the control device 32 is provided with a control panel. The operator can control the drive device 204, the first hydraulic device 203, the second hydraulic device 301, and the third hydraulic device 31 via the control panel.
In summary, the invention provides a printing device for heating resistor paste, wherein a placing platform for placing a ceramic tube to be printed is arranged below a screen printing device, when the ceramic tube is printed with the heating resistor paste, the screen printing device can move horizontally above the ceramic tube, and a scraper blade is kept stationary in the horizontal direction and keeps a mutual extrusion state with the ceramic tube, so that the ceramic tube on the placing platform can be pulled to rotate in the moving process of the screen printing device, thereby enabling the heating resistor paste to be uniformly printed on the tubular ceramic tube, and improving the heating effect of the ceramic tube.
It should be understood that equivalents and modifications of the technical solution and inventive concept thereof may occur to those skilled in the art, and all such modifications and alterations should fall within the scope of the appended claims.
