Description

An ink-filling structure for a pad printing machine with patterns distributed in a large-diameter circle

technical field

The utility model relates to the technical field of ink printing, in particular to an ink filling structure of a pad printing machine with patterns distributed in a large-diameter circle.

Background technique

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 picks up the ink filled in the concave pattern and imprints it on the surface of the printed workpiece to complete the pad printing process. Obviously, to fill the ink with the pattern on the pad printing plate, it is necessary to make the motion track of the ink cup completely contain the pattern.

The existing pad printing machine uses a circular oil cup to make a reciprocating linear motion on the pad printing steel plate to fill the concave pattern on the surface of the pad printing steel plate with ink. The movement track of the oil cup is a width equal to the diameter of the oil cup , a rectangle whose length is equal to the amplitude of the reciprocating motion of the oil cup, so to completely cover the pattern requires that the diameter of the oil cup is not less than the maximum width of the pattern. However, it is necessary to print special-shaped patterns on some products. For example, the patterns are distributed in a circle with a large diameter. At this time, if the rectangular motion trajectory generated by reciprocating linear motion is used to contain such patterns, the diameter of the oil cup needs to be larger than the pattern contained. The diameter of the circumference, the oil cup with a large diameter increases the cost, and also increases the pressure and wear on the pad printing steel plate.

For example, in the existing public documents, there is a Chinese patent document with the announcement number CN203331568U and the announcement date of 2013.12.11, which discloses a new oil cup pad printing machine, including a frame, a cross bar, and a template. The crossbar is fixedly connected to the frame, and it is characterized in that: a printing head is installed on the base, a base is provided at the lower end of the crossbar, a template is connected to the left end of the base, a scraper is arranged above the template, and the A steel plate is connected to the cross bar, and an oil cup is installed on the steel plate. The utility model has the general advantages of the oil cup type pad printing machine, that is, the ink is sealed in the oil cup, the volatilization is small, the ink can be used for a long time and has less environmental pollution. The disadvantage of this technical solution is that the movement mode of the oil cup in the structure of the utility model is a reciprocating linear motion. When the pattern is distributed in a circle with a larger diameter, a larger diameter oil cup is needed to make the ink The movement trajectory covers the pattern to complete the ink coating, which increases the cost, and also increases the pressure and wear of the oil cup and the pad printing steel plate.

Utility model content

In order to solve the problem that the existing pad printing machine needs to be equipped with a large-diameter oil cup when filling the pattern in the large-diameter circle, increasing the cost, increasing the pressure and wear between the oil cup and the pad printing steel plate, this practical The new type provides a small-sized oil cup to complete the ink filling operation when the pattern is distributed in a larger-diameter circle, which is low in cost, and the pressure and wear between the oil cup and the pad printing plate are small in the large-diameter circle Pad printer ink filling structure for distributed pattern.

In order to achieve the above object, the technical solution adopted by the utility model is:

An ink-filling structure of a pad printing machine with patterns distributed in a large-diameter circle, including an oil cup and a pad printing steel plate. The pad printing steel plate has concave patterns distributed in the circumference, and the left and right sides of the pad printing steel plate have guide grooves. The left and right guide grooves are equipped with guide blocks respectively, the upper section of the guide blocks extends upwards, the upper ends of the two guide blocks are bridged by a beam, the lower end of the beam is provided with a vertical rotating shaft, and the lower end of the rotating shaft is connected with a Connecting rod; one end of the connecting rod is connected to the rotating shaft, the other end of the connecting rod is connected to the oil cup, and the lower end of the oil cup is pressed on the printing plate. The oil cup has two movements, one is to do reciprocating linear motion synchronously with the beam, and the other is to make circular motion around the rotation axis with the connecting rod. Its motion trajectory is a circle with a diameter larger than the diameter of the oil cup. , the radius of the circle is the distance from the rotation axis to the outermost end of the oil cup, which can realize the ink filling operation of the distribution pattern in the large diameter circle with a smaller diameter oil cup, low cost, small size of the oil cup, The quality can be reduced, the pressure and wear between the oil cup and the pad printing steel plate are small, and the service life of the oil cup is prolonged.

Preferably, the guide groove is a dovetail groove.

Preferably, the diameter of the oil cup is 1 to 2 centimeters larger than the radius of the circle where the depression pattern is distributed. Setting a surplus of 1 to 2 cm can ensure that the movement track of the oil cup completely covers the concave pattern and ensures the integrity of ink filling.

The beneficial effects of the utility model are: the oil cup with a smaller diameter can be used to complete the ink filling of the distribution patterns in the large-diameter circle, the cost is low, and the pressure and wear between the oil cup and the pad printing steel plate are small.
