A pad printing machine for the scale line of a syringe barrel

Abstract

The invention provides a transfer printing machine for scale lines of syringe needle cylinders, which belongs to the technical field of machinery and resolves the problem that an existing transfer printing machine for scale lines of needle cylinders is low in applicability and high in cost. The transfer printing machine comprises a machine base and a rotating disc located on the machine base, the rotating disc is connected with a power mechanism, the power mechanism can drive the rotating disc to rotate relative to the machine base, a plurality of guide rods peripherally fixedly connected with the rotating disc are uniformly distributed along the periphery of the rotating disc, the machine base is provided with an annular cam, the upper ends of the guiding rods are in lap joint on the annular cam, the machine base is provided with a guiding plate, positioning blocks are arranged on sides of the lower ends of the guiding rods, a positioning cavity is arranged between the positioning blocks and the guiding plate, by the aid of the positioning blocks, a needle cylinder lug seat trends to be in lap joint onto the top of the guiding plate, a pressure plate connected onto the guiding plate is arranged right below the highest position of the annular cam, a gap is reserved between the pressure plate and the guiding plate, the needle cylinder lug seat is inserted into the gap, and a scale line printing device is arranged at the position of the pressure plate. The transfer printing machine has the advantages of wide service range, simple structure, low production cost and the like.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a pad printing machine, in particular to a pad printing machine for syringe syringe scale lines. Background technique [0002] Medical syringes need to have scale marks printed on their outer walls to facilitate the use of medical staff. The method of printing scale marks on the syringe can be screen printing, but screen printing has the disadvantages of slow speed, personnel operation and adjustment during the printing process, and easy wear and tear of the screen. Therefore, people began to use pad printing to print the scale line of the syringe. However, because the printing position of the scale line of the syringe has special requirements, the printing accuracy is high, and no deviation can occur, and the directional printing of the scale line of the syringe cannot be completed by using the existing pad printing machine. [0003] In order to solve the above problems, peopl...

AI Technical Summary

Problems solved by technology

[0004] The needle cylinder scale line printed by the above-mentioned pad printing machine for the needle cylinder scale line is in the same position, but the position of the needle cylinder needs to be fixed by the cooperation of the pressing rod and the supporting mechanism, which makes the structure of the pad printing machine more complicated and the cost is higher

In addition, the size of the positioning notch used to locate the position of the needle cylinder in the pad printing machine for the marking line of the needle cylinder cannot be adjusted, so that the pad printing machine cannot print the scale lines of needle cylinders of different specifications, and the range of use is small, and the applicability not tall
