Referring to the effects of the present invention as described above are as follows.

When power is supplied to the heat generating unit 22 by supplying power to a control box (not shown), electricity transferred to the heat generating unit 22 passes through the heating wire 52 of the heat generating unit 22 'as shown in FIG. 10. As shown in FIG. 11, the upper mold 6 is heated by passing through the wiring pipe 53 installed at the bottom of the rear surface of the body 1 to the heater 5 embedded in the upper mold 6. The high temperature generated at this time prevents heat loss as much as possible by the upper high temperature prevention piece 54.

After a while, if the temperature of the upper mold 6 is maintained at 170 to 180 degrees, turn on the motor power switch of the control box.

As such, the temperature of the upper mold 6 is always kept constant so that the temperature sensed by the temperature sensing unit 21 is transmitted to the automatic control box (not shown) and is kept constant.

When the main motor 31 is rotated by turning on the power switch, the power transmitted to the rotating belt 32 is transmitted to the driving reducer 33 to rotate the small spur gear 34. Since the power transmitted to the small spur gear 34 rotates in engagement with the large spur gear 26 at the bottom of the rotary support piece 23, the support rotating body 25 fixed on the bearing shaft 24 starts to rotate. Done. At this point, all operations begin to move simultaneously.

When the large spur gear 26 fixed to the rotary support piece 23 is simultaneously moved by the rotation of the support rotating body 25, the bevel gear 38 engaged with the front part is also rotated to be fixed to the transmission shaft 40. The lower chain gear 39 moves the chain 44 to operate the upper chain gear 39 '.

By rotating the upper chain gear 39 ', the operating spur gear 45', which is fixed to the rotary roller shaft 43, is rotated so as to rotate to rotate the operating spur gear 45 '. ') Rotates at the same time. When operating in this way wood material 55 is not introduced and the rotating body (1) proceeds to the state as shown in Figure 12a.

This idling is because the spring 46 at the tip of the upper chain gear (39 ') serves to adjust the strength. At this time, the cam 11 'part of the eccentric shaft 11 is lowered to the lower part in the state like FIG. 12c. When the rotating bearing 13 proceeds to the top dead center 57 after passing through the bottom dead center 56 of the forced rotational auxiliary piece 50 on one side, the eccentric shaft 11 rotates little by little and the cam as shown in FIG. When the (11 ') part is deviated from the lower end of the eccentric shaft (11) and the operation rod (15) is pulled up a little, the operation interval (7) coupled with the operation rod (15) is the guide groove (8) to guide the body (1). Ascend slightly upward along flight (2).

At this time, the upper mold (6) is slightly separated from the lower mold (6 ') while the guide bearing (20) of the lower mold (6') as shown in Figure 8 the lower rail rail groove of the guide rail piece 37 The interlocking bearing 19 introduced into the point (B) entering the (36) and interlocked with the legs 18 on the back of the body 1 is the upper end of the guide rail 29 of FIG. B ') is put on the point.

In this state, when the rotary support piece 23 is continuously rotated, the interlocking bearing 19 seated on the guide rail 29 continues to rise upward to reach the point (C ') of the guide rail 29, thereby interlocking bearing. The lecks 18 coupled with (19) are also raised upward to rotate the spur gear 12 fixed to the eccentric shaft 11, which is interlocked with and inserted into the axial hole 9 'of the eccentric shaft fixing plate 9, and operates forward. The piece 14 is rotated to the opposite side as shown in Fig. 15a so that the cam 11 'portion is placed at the highest height, so that the actuating rod 15 is pulled up to the maximum so that the guide groove 8 of the operation period 7 is guided ( If the upper mold (6) is raised upward according to 2) it is in a state of falling completely.

At the same time, the guide bearing 20 located at the lower rail rail groove 36 (B) of the guide rail piece 37 reaches the point (C), which is the starting point of the upper rail groove 35, so that the top of the guide bearing 20 is The moving piece 3 'of the lower mold 6' fixed to the shaft 20 'moves forward along the operating rail 3 to connect the bottom surface of the lower mold 6' with the guide bearing 20. Pulled forward along the long groove 4 of the bottom of the body 1, the lower mold 6 'is completely pulled forward as shown in FIG. 15B.

In this process, if the molded part of the lower mold 6 'coincides with the lower end of the material guide rails 27 and 27' into which the wood material 55 is injected, the wood material (see Fig. 15b) in the lower mold 6 '. 55) will be seated.

The guide bearing 20 of the lower mold 6 'and the interlocking bearing 19 of the leg 18 move along the guide rail piece 37 and the guide rail 29 while the seating of the wood material 55 is in progress. Then, when the guide bearing 20 of the lower mold 6 'arrives at the point (D) and the interlocking bearing 19 reaches the point (D'), the guide bearing 20 is ready to be returned to the initial state.

At this time, the cam 11 'portion of the eccentric shaft 11 is in the highest state. Here, the guide bearing 20 reaches the point (E) of the lower bottom rail groove 36 'opposite the guide rail piece 37, and the interlocking bearing 19 linked to the rack 18 is along the guide rail 29. Upon reaching the point (E '), the lower mold 6' coupled with the guide bearing 20 is instantaneously matched to the lower end of the upper mold 6, and the interlocking bearing 19 is also guide rail 19 at the upper mold 6 side. As the eccentric shaft 11 continues to rotate while descending the inclined surface of the cam), the cam 11 'portion moves as shown in FIG.

When the interlocking bearing 19 completely reaches the point (E ') of the guide rail 29, the lever 18 is lowered to its initial position and the operating piece 14 is also returned to its original position.

As shown in FIG. 17B, the lower mold 6 ′ and the upper mold 6 coincide with each other, and heat of 170 degrees to 180 degrees is applied to the recess of the wood material 55.

The lower bottom guide piece 30 fixed to the upper bottom point of the guide rail 29 primarily helps to lower the interlocking bearing 19 safely, and the guide piece 58 shown in FIG. 3 actuates the actuating bearing 13. Secondary help to ensure that the upper and lower molds (6) (6 ') in the initial state completely.

In this state, when the guide bearing 20 is out of the (F) point of the guide rail piece 37, the body (1) portion which was rotated and proceeded by being rotated along the rotating support piece (23) is first described. When reached to the forced rotational auxiliary piece 50, such as the movement of the description of FIG. 13 and the groove formed molded spoon is pushed forward, such as the lower mold (6 ') material guide rails (27) (27') Rising upward by the rotation of the rubber belt (51) (51 ') in the left direction of the will be gathered below along the material guideway (59). This work process is one cycle.

And the large spur gear (26) at the bottom of the rotary support piece (23) is supported by a number of auxiliary bearings (60) to maintain the horizontal and the lower motor (61) debris or dust generated when the wood material 55 is injected Inhale.

An oil hole 62 'is formed in the upper cover 9, and the oil inlet 62 is coupled to the oil rail 63 on the operating rail 3 of the body 1 to inject oil well.

The lower chain gear 39 on the transmission shaft 40 when it is not inserted into the lower mold 6 'due to more than the wood material 55 introduced into the material guide rails 27 and 27' in the course of operation. By pushing one side of the auxiliary shaft 49 of the uneven groove operating piece 48 which is combined with the uneven portion 47 of the uneven portion 47 and the uneven groove operating piece 48 is separated and the transmission shaft 40 only As it is idling, it can process the work quickly. If you want to introduce the material again after the rapid processing of the bad wood material, pull the auxiliary shaft 49, which separated the uneven groove working piece 48, to the uneven groove operation. When the piece 48 and the concave-convex portion 47 of the lower chain gear 39 coincide with each other, the upper chain gear 39 'is operated by the chain 44 to inject the material.

According to the present invention, the wood material is first sterilized in a high temperature sterilization chamber to make a wooden spoon shape, and then the second high temperature sterilization process, followed by the third heat sterilization at the same time as the spoon groove part is formed by the heat of the molding machine. As it is treated, it maintains perfect sterilization effect and it is hygienic. It is good to use with soft touch on the surface of grooves, and you can feel the beauty of wood pattern as well as the simple operation process by automation, which can reduce the production cost by mass production.
