Description

Supporting materials for thermal head of silk-screen plate making device

The present invention is to give the thermal head support member for forming a printing pattern on the screen portion of the silk screen to give a uniform pressure when forming the printing pattern on the silk screen as a whole to obtain a screen printing pattern of uniform quality It is.

In general, a silk screen making apparatus is a kind of a sheet forming apparatus that forms a printing pattern on a silk screen by using a thermal head. Image information transmitted while a thermal head moves a screen printing area of a silk screen by an exercise device. Accordingly, the thermal emulsion applied to the screen is partially heat-sensitive to form a printing pattern through which ink can pass.

Conventionally used silk screen making apparatus has a problem that the thermal head is located on the top of the silk screen and the pressure roller is installed on the bottom of the silk screen to heat the upper surface of the screen. For example, the wires connecting the thermal head and the controller (such as a power supply line or a signal line) are also positioned along the top of the screen and move along the thermal head.

Therefore, the wires are exposed to the outside, so that not only the overall aesthetics are lowered, but also a means for preventing the wires from sagging downward due to its own weight is required, and the movement load of the thermal head is raised by the sag preventing means. In addition, since the wires are lifted and flowed somewhat according to the movement position of the thermal head, there is a problem of rapid damage of the wires.

In addition, since the thermal head is installed horizontally and parallel to the screen, there is a problem that the moving load is increased when the printed pattern is formed.

On the other hand, in order to solve the above problems, the present inventors inclined to install the thermal head of the plate making apparatus to be positioned below the screen of the silk screen mounted on the table to reduce the thermal load by providing a stable and even tension of heat. Patent Application No. 2003-23937 (July 24, 2003) filed "The thermal head mounting structure of a silkscreen plate making apparatus" to prevent interference and to achieve excellent plate making (or printing pattern).

1 shows the configuration of the silk screen making apparatus 1 proposed in the utility model, a frame 2 having an opening portion 3, a table 6 on which the silk screen 4 is mounted, and silk. A quick clamp 8 for fastening the screen 4 to the table 6, a spring plunger 9 for holding the silk screen 4, and a thermally inclined bottom of the screen of the silk screen 4 to be mounted. The head 10, the supporting member 12 holding the thermal head 10, the exercise device for moving the thermal head 10, and the screen at a sufficient pressure when the thermal head 10 heats the screen. Press paper 14 for pressing and holding the touch screen to reach the heat-sensitive portion, and the press paper for lifting the press paper roller 14 temporarily so that the silk screen 4 can pass through when the silk screen 4 is mounted on the table 6. A roller lifting mechanism 16, an electric wire 20 electrically connecting the thermal head 10 and the controller 18, and the electric wire 20 Is composed of a receiving-type flexible chain duct 21 it is.

In addition, the thermal head exercise mechanism is a slide slidingly coupled to the guide rods 22 and 24 and the guide rods 22 and 24 installed in parallel to the frame 2 as shown in FIGS. 1 and 2. (26) (28), a supporting member (12) connecting the two slides (26) and (28) to each other, a thermal head (10) fixed to the upper surface of the supporting member (12), and a controller (18) of A motor 30 under control, a reduction mechanism composed of a plurality of timing pulleys 34 and a timing belt 32, and are installed in the longitudinal direction of the guide rods 22 and 24, and are stationary by the motor 30. Timing pulleys (40) (42) (44) (46) and shaft (48) and scale adjusting means for elastically supporting both ends of the rotating timing belts (36) (38) and the timing belts (36) (38). Fixing means 54 for fixing the slides 26 and 28 to the timing belts 36 and 38 so that the slides 26 and 28 and the thermal head 10 can be moved. (56).

On the other hand, when the supporting member 12 to which the thermal head 10 is fixed is a flat plate type without a holding means as shown in FIG. 3, when the thermal head 10 is formed and a printed pattern is formed, the blotting roller 14 as shown in FIG. 4. Pressure is applied through both ends 72 of the, and the pressure of the thermal head 10 is supported only on both sides of the support member 12, so that the center portion of the press roller 14 is bent toward the upper side, and the thermal The central portion of the head 10 and the support member 12 are bent downward. As a result, the pressure in the center of the paper holding portions of the paper holding rollers 14 and the thermal head 10 is weakened to maintain a uniform pressure, so that an even pressure is not maintained as a whole so that between the paper holding rollers 14 and the supporting member 12 is not maintained. The uniform contact is not made, and when looking at the plate making result, since the concentration of the central portion is significantly lower than both sides of the high pressure, the screen pattern is not formed uniformly, so the plate making quality is deteriorated.

In addition, even if the holding force of the holding roller 14 is uniformly provided, both edge portions on which the supporting member 12 is fixed are held firmly by the slides 26 and 28, but the center portion of the supporting member 12 is maintained. Since there is no such support means, the bending is easily caused, resulting in unevenness of the bearing force.

Therefore, since the supporting force and the degree of thermal sensitivity of the support member 12 decrease as the transition from the edge portion of the thermal head 10 to the center portion, the print pattern formed on the screen also does not print clearly as the print pattern is formed toward the center. The bottom side is large because it is not given even support force to the support member 12 by the above structure.

Accordingly, an object of the present invention is to provide a thermal function to the thermal head support member of the silk screen making apparatus so that a uniform support force is applied to the screen, thereby forming a screen printing pattern having a uniform quality.

In order to achieve the above object by forming a long hole on both sides with respect to the center of the support member to form a carbon portion to form a print pattern while moving the thermal head 10 as shown in Figure 6 72, a pressure is applied, and the pressure of the thermal head 10 is supported by the center of the supporting member 12, so that the center portion of the plunger roller 14 is bent upwards, and the thermal head 10 And both side portions of the support member 12 is bent toward the lower side. That is, the pressure point of the supporting member 12 is moved from two places on both sides to the center, and the presser parts 12d and 12e are formed on both sides of the supporting member 12 to be applied at the center of the blotter roller 14. As a result of the pressure, the pressure is received from the tungsten portions 12d and 12e of the supporting member 12 so that the even holding force of the thermal head and the squeezing roller fixed to the top is maintained to obtain a more uniform and superior screen printing pattern. do. The finger hole can be evenly adjusted by adjusting its width, formation pattern and formation length.
