Description
Technical Field
The invention belongs to the technical field of machinery, and relates to a pad printing machine for scale lines of a syringe.
Background
At present, the printing of the scale marks on the syringe is basically finished by a pad printing machine. The traditional pad printing machine is very simple and comprises a rotary disc which can rotate and is provided with an arc notch at the edge and a printing device arranged on one side of the rotary disc, wherein the side part of a needle cylinder is clamped at the arc notch, then the needle cylinder is conveyed to the printing device by the rotary disc to form contact, and the printing device drives the needle cylinder to rotate relative to the rotary disc to complete printing. However, in actual mass production, it has been found that the orientation of each cylinder cannot be maintained until it comes into contact with the printing apparatus, resulting in deviation in the orientation of the scale marks printed on each cylinder.
In order to solve the above problems, the chinese patent proposes a pad printing machine of 200920315249.6 application number for cylinder scale marks, which comprises a machine base and a rotary table arranged on the machine base, the rotary table is connected with a power mechanism, the power mechanism can drive the rotary table to rotate on the machine base, the edge of the rotary table is provided with a plurality of positioning notches which are uniformly distributed along the circumference and can position the cylinder ear seats, the side part of the rotary table is provided with a scale mark forming device which can be abutted against the outer side wall of the cylinder arranged at the positioning notches, the rotary table is connected with a pressure lever which can rotate together with the rotary table and can slide up and down relative to the rotary table, a lifting mechanism which can lift the pressure lever along with the rotation of the rotary table is arranged between the upper end of the pressure lever and the machine base, the lower end of the pressure lever corresponds to the position of the positioning notches, a jacking mechanism is arranged on the machine base opposite to the scale mark forming device, and the jacking mechanism and the pressure lever can be jacked at the two ends of the cylinder and away from the positioning notch. The positioning notches are arranged on the rotary disc, so that the needle cylinders before printing are completely consistent in orientation, and the printed scale marks can be kept consistent in orientation.
However, the pad printing machine for the needle cylinder scale marks has some defects: the needle cylinder lug seat is required to be separated from the positioning notch during printing, the separation of the needle cylinder lug seat and the positioning notch depends on that a jacking mechanism capable of jacking the needle cylinder lug seat upwards is correspondingly arranged below the edge of the rotary table, but the position below the rotary table in the complete pad printing system is very crowded and complicated (because a plurality of transmission mechanisms are arranged below the rotary table), the arrangement of the jacking mechanism can make the structural arrangement of the position more unreasonable, and the distance between the jacking mechanism and a scale mark printing device cannot be too large or too small, and the too large situation can cause insufficient contact to form printing and the too small situation can cause interference. In this case, the conventional technical means of those skilled in the art is to make the volume as large as possible so that there is enough space below the turntable to be able to arrange.
Disclosure of Invention
The invention aims to provide a pad printing machine for scale lines of a syringe of an injector aiming at the problems in the prior art, and solves the problem of unreasonable structural arrangement while ensuring consistent printing directions of the syringe.
The purpose of the invention can be realized by the following technical scheme:

In an initial state, the lower end of the guide rod is positioned at a low position, so that the side parts of the needle cylinder lug seats can be abutted against the convex blocks to form positioning of the needle cylinder, and the position of the needle cylinder before printing can be kept consistent. When the turntable rotates to the position where the needle cylinder is located in the printing device, the guide rod is lifted downwards under the action of the highest position of the upper end surface of the annular cam, so that the lug is separated from the needle cylinder lug seat. Meanwhile, the upper end of the compression bar is abutted against the lower end face of the limiting block, so that the compression bar cannot be lifted upwards along with the guide rod, and the lower end of the compression bar is equivalent to extend out of the positioning sleeve and abut against the end face of the needle cylinder lug. The lug is separated from the needle cylinder lug seat, so that the needle cylinder can rotate by matching with the action of the printing device to complete the printing of the scale mark; and the action of the pressure lever ensures that the needle cylinder cannot jump upwards in the printing process, thereby ensuring the printing reliability of the needle cylinder. Through the setting of above-mentioned structure for the cylinder not only can be fixed a position before the printing, need not to be lifted up again when the printing simultaneously, can directly realize the release of cylinder location by the upwards slip of guide arm, and prevent upwards beating of cylinder with the help of the downward promotion of depression bar, the use of mechanism is held in top has been cancelled from this, and the cooperation of depression bar and arc piece etc. all sets up the space in annular convex part top, upwards arrange in other words and reduce the requirement in horizontal space, thereby make the structure can make things convenient for more, arrange rationally.
