Workpiece table capable of fixing printing workpiece for pad printing machine

Abstract

The invention discloses a workpiece table capable of fixing a printing workpiece for a pad printing machine. The workpiece table comprises a carrier, and a positioning assembly, wherein the upper sideof the carrier is provided with a profiling groove for accommodating the printing workpiece and 2n symmetrically arranged guiding through grooves which communicate with the profiling groove, and N isa positive integer; the positioning assembly is provided with 2n positioning blocks arranged corresponding to the 2n guiding through grooves and a power mechanism connected with the 2n positioning blocks; the 2n positioning blocks surround the carrier, and each positioning block is located in the extending direction of the corresponding guiding through groove; and the power mechanism is used fordriving the 2N positioning blocks to move linearly towards or away from the profiling groove along the corresponding guiding through grooves simultaneously. According to the workpiece table, the printing workpiece can be stably and reliably fixed in the workpiece table, so that the phenomenon that the position offset of the printing workpiece occurs, and even the printing workpiece is separated from the workpiece table in the oil printing process is effectively prevented.

Description

technical field [0001] The invention relates to the field of ink printing equipment, in particular to a work table for a pad printing machine that can fix a printing workpiece. Background technique [0002] The working principle of the oil cup pad printing machine is: the oil cup filled with ink moves back and forth in a straight line on the surface of the pad printing steel plate, and the ink in the oil cup fills in the concave pattern on the surface of the pad printing steel plate during the movement; The pad printing rubber head moves vertically downwards to pick up the ink filled in the concave pattern, and then translates to the top of the workpiece table where the printing workpiece is placed in advance, and then moves downwards to stick the ink on the surface of the pad printing rubber head. The ink forming the recessed pattern is imprinted on the surface of the printing workpiece. It is easy to understand that whether the position of the printing workpiece on the wo...

Problems solved by technology

The current problem is that the existing workpiece table locates the printing workpiece by setting a profiling groove on the surface that matches the contour of the printing workpiece. Obviously, this positioning method is not reliable enough. When there is shaking or vibration, the printing workpiece placed in the profiling groove is very likely to shift its position or even break away from the profiling groove, which will cause the ink that forms a concave pattern on the surface of the pad printing head to fail to press. It is printed on the correct position of the printing workpiece, and even causes the printing workpiece to be deformed or crushed during the process of pressing down the pad printing rubber head
