The guide bar can adjust the platen position to the position of the fixed platen of pulling force through locating piece and first cylinder makes the location of platen more accurate, improves the efficiency of location.
Preferably, a support frame is installed below the longitudinal support, a second cylinder is installed below the support frame, and the second cylinder is electrically connected with the control device. The second cylinder drives the support frame to move up and down, so that the height of the positioning device can be adjusted, and the table is suitable for tables with different heights.
Preferably, the contact position of the positioning block and the bedplate is provided with a saw-toothed protrusion, and the bedplate is provided with a groove matched with the protrusion. The accuracy and the stability of location can be further improved through mutual cooperation of the protrusion and the groove.
Preferably, the object carrier and the bedplate are made of magnetic conductor materials, and the object carrier is electrically connected with the control device. The bedplate is firmly fixed on the object carrier through the magnetic attraction effect, and the stability of the bedplate is improved.
Compared with the prior art, the utility model discloses the beneficial effect who has does: this positioner of platen of calico printing machine can avoid the platen when the location or fix a position the back during operation and take place to remove, guarantee the stability of platen, improve the stamp quality, the guide bar can be adjusted the platen position simultaneously, and the position of the fixed platen of pulling force through locating piece and first cylinder, make the location of platen more accurate, improve the efficiency of location, further drive the support frame up-and-down motion through the second cylinder, thereby can adjust positioner's height, the platen that adapts to not co-altitude uses.
The present invention will be further explained with reference to the drawings and examples.
