Abstract

PURPOSE:To prevent the rise of temperature due to the heating of driving part as well as keep the high performance of the printing head of a wire dot printer, by providing a heat pipe extending from the inside of the head to the outside and also a heat radiator on the outside of the heat pipe. CONSTITUTION:A printing head 1 is fixed to a carriage 2 by a fixing screw 13. Also, the inside of the printing head 1 is provided with part of a heat pipe 14 in such a way that the heat generated inside can be moved to the outside. A heat radiator 15 is attached by brazing to the extended part to the outside of the printing head in the heat pipe 14, by which heat transmitted from the heat pipe 14 can be radiated effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to a wire print head.

In general, Tsuiyadot Plan I has sP%A,
Dark letter O printing! ! Damn it, 5. With the improvement of egg production quality and speeding up, the print head O wire drive has become smaller.
Mysteries are being performed on 11th graders. However, the size of the tsuya drive tool as described above is small, the height is high,
The rear drive is made up of a JL, and the heat generated by the heat generation and the iron loss of the magnetic O is good. It happened. ζO good,
Conventionally, in order to prevent the above-mentioned O failure, we have discussed O countermeasures such as detecting the temperature of the print head s at 7 t- and making sure that the temperature JIE exceeds a certain value and the printing mode is uniform. One thing is ζO
If the site IIca printing oII4 generalization is impaired, it will have disadvantages and IL: because.

The present invention was proposed in 9 J6 to eliminate the above-mentioned drawbacks of the conventional technology. 4s
Our objective is to provide a print head that can always maintain maximum OS performance without any reduction in performance.

The following is based on a drawing showing a preferred embodiment of the present invention.
Details #Kl! I will clarify.

), l is the print head, snow is the middle shaft on which the print head 1 is mounted, 3 and 4 are the carriage 20 horizontal movement), and the guide shaft is within 11 m and is supported between the TonH plates 10 and 11. Mara, 2 is the drive wire, 6 is the drive motor, 7 is the large pulley attached to IK# motor 6, $ is the guide pulley &),
The 70-m was 111cmff under the carriage 30 along with the *1lII to Goo 17 via the SaS Idopuri Hatake. Therefore, Kukkengo-zsoa
The carriage 2 is guided and driven on the j-id axis 3.4 by the rotation. Incidentally, the side plate 11K can be attached to the platen, 12 is the print head IKjLt, and the side plate 11K is used for cooling.

Next, No. A11O Moum Danryo fat, So 2 Ji and Sow.
Regarding the print head IK according to the embodiment of the present invention for No. 31111, which is M-en! I will clarify.

1! #ill fixing screw 13, the print head 1 is fixed to the middle spear 3 by this fixing screw 13. The heat pipe 4 is a heat pipe 66, a part of which is enclosed within the print head 10 and is attached in a continuous shadow from the inside of the print head 10 to the outside 11. This heat pipe 14 is O-〇 in order to move the heat generated inside the print head 1 to the outside. Xi Hato-Dopaibu 141
0 The print head 1 is attached to an appropriate length part of the outer body (by brazing, etc.) and is a good heat radiator), and has a vibrating area with the air (heat radiation area).
It has a shape in which a large number of folds 15' are formed in a rounded shape.
The heat inside the print head is efficiently dissipated by conducting the heat. In this ζ, the material of the k-doped pipe 14 and the heat dissipation 815 is copper or aluminum with good thermal conductivity.
Ugosei shall be used. Furthermore, l is the drive wire S
There is a next bottle to be hung, and it is press-fitted under the carriage 20.

In addition, the heat dissipation mentioned above! When dissipating heat by 15 K, it is dissipated by a cooling fan 12 as shown in Figure 1.
It would be possible to effectively dissipate heat by performing air cooling in step 5).

The print head according to the present WA is constructed and operates as described above, and thus provides the Kameyoshimaru effect as described below.

Heat generated inside the print head is transferred to the outside via a heat pipe.
c) Efficient heat dissipation (heat conduction and heat radiator) inside the print head 5
Since it is possible to suppress the rise in osi degree to a low level (11Jl+), there is no need to install a temperature detection sensor to detect the temperature and adjust the printing speed.
There is no point in impairing India's #PO speed-up. Therefore, it is possible to provide a print head that can always maintain the highest level of performance.
