Abstract

The invention relates to a drive and control circuit for impact force increasing of a needle type printing head and a control method of the drive and control circuit. The drive and control circuit comprises a power supply, a coil load module U1, a coil load drive module U2, a complementary energy quick releasing module U3 for recycling a part with complementary energy, a second reverse isolation module U4, a first reverse isolation module U5 and a coil energy recycling module U6; the coil load drive module U2 is further connected with a main sequence circuit T1; the main sequence circuit T1 is used for generating an electromagnetic force to a drive and control coil so as to discharge needles; and the first reverse isolation module U5 and the coil energy recycling module U6 are connected with a sequence circuit T2, and are used for recycling energy. Double sequence drive and control and a new quick energy releasing module are adopted, a function of recycling the complementary energy in a sectional manner is fulfilled, power consumption of a whole printer is greatly reduced, and heating is reduced; and meanwhile, the impact force of the printer is increased, the printing effect is improved, and double functions of saving energy and improving printing effect are fulfilled.

Description

technical field [0001] The invention relates to the technical field of printer equipment, in particular to a driving control circuit and a control method for a dot-type printing head to increase striking force. Background technique [0002] The print head of needle printing is an electromagnetic coil product. The printing needle generates an electromagnetic field through the coil, and the needle handle moves under the action of the electromagnetic field. The movement of the needle handle drives the flying needle of the printing needle to hit the ribbon, and the ink of the ribbon is transferred Printing on paper, and at the same time, in the application of multi-layer carbon paper printing, the pressure is generated by the impact of the printing needle to achieve multi-layer copying. Based on the working principle of dot matrix printers, the striking force and striking time of the printing needle determine the printing effect. The greater the striking force and striking time,...
