One measuring end of the first shaft rod 30 is axially installed on the bottom surface of the gearbox 20, and the other measuring end is axially installed on the front cover plate 32 of the gearbox 20. The first shaft 30 has a large-diameter first helical gear 34 meshed with the small-diameter helical gear 28 and a second smaller diameter than the diameter of the first helical gear 34.
The helical gear 36 is integrally formed, and the key 38 is integrally formed in front of the second helical gear 36.

On the other hand, a second shaft rod 40 is axially provided adjacent to the small diameter helical gear 28 of the motor rotating shaft 26. The second shaft rod 40
Are arranged at positions that are substantially diametrically opposed to the first shaft 30. One end of the second shaft rod 40 has a gearbox 20.
The other measuring end portion extends through the front cover plate 32 to form a square end portion 41, to which the squeezing roller 16 is connected. A large-diameter third helical gear 42 that meshes with the second helical gear 36 of the second shaft 40 is integrally formed, and a key 44 is formed in front of it.

Thus, the first and second helical gears 3 are
The first shaft rod 30 in which 4,36 are integrally formed and the second shaft rod 40 in which the third helical gear 42 is integrally formed are such that the rotational force transmitted from the rotary shaft 26 of the motor is decelerated. The structure of the speed reducer is configured to be transmitted to the squeezing rollers 16 and 17 through the square end portion 41 of the second shaft rod 40.

As mentioned above, the squeezing roller 17 is independently connected to the rotary support rod 46 attached to the front cover plate 32 independently of the structure of the speed reducer.

From the speed reducer structure mentioned above, the rotational force is sequentially applied to the helical gear 28 of the rotary shaft 26, the first helical gear 34 of the first shaft rod 30, the second helical gear 36 and the second shaft rod 40. Three

According to the present invention, a first clutch gear 48 and a second clutch gear 50 are inserted into the first shaft rod 30 and the second shaft rod 40, respectively. The first clutch gear 48 has an inner hole formed with a key 52 which is coupled to the key 38 of the first shaft 30 and connects the first clutch gear 48 to the first shaft 30. The structure is such that a sleeve 56 having a flange 54 is extended forward. Therefore, an annular groove 58 is formed between the flange 54 and the side surface of the clutch gear 48.

Similarly, the second clutch gear 50, like the first clutch gear 48, has a key that is coupled to the key 44 of the second shaft 40, and a sleeve 66 having a flange 64 that forms an annular groove 62. Are formed.

Coarseness, first and second clutch gears 4
8 and 50 are movable on the first and second shaft rods 30 and 40 in the axial direction of the shaft rods 30 and 40 between the inner surfaces of the second and third helical gears 36 and 42 and the front cover plate 32, respectively. ing. For example, when the first clutch gear 48 comes close to the second helical gear 36 of the first shaft rod 30, the key 38 of the shaft rod 30 and the clutch gear 48.
When the key 52 is connected, the first shaft rod 30 and the first clutch gear 48 are mechanically connected and the clutch gear 48 is connected to the shaft rod.
Will rotate with 30. If the clutch gear 48 moves to the front cover plate 32 side, the key 38 of the shaft rod 30 and the key 52 of the clutch gear 48 are separated, and the shaft rod 30 clutch gear 48 is separated. Similarly, the second clutch gear 50 is connected to the second shaft rod 40.
When approaching the third helical gear 42, the second helical shaft 42 is coupled to the second axial rod 40, and when the third helical gear 42 is moved to the front cover plate 32 side, it is separated.

A coupling gear 68 is coupled to the first and second clutch gears 48 and 50 inserted and coupled to the first and second shaft rods 30 and 40 as described above. A short shaft 70 is integrally extended to the connecting gear 68, and a tip portion of the short shaft 70 penetrates the front cover plate 32 to extend to the front surface of the main body 14 and a screw portion 72 is formed at the end portion. The screw portion 72 is screwed into a screw hole 73 formed in the upper portion of the cylinder 22 on the body coupling surface side of the housing 18.

The first and second clutch gears 48,50 referred to above are selectively adapted to the respective first and second shaft rods 30,40.
A means for mechanically coupling to is a clutch actuation fork 74. The clutch actuating fork 74 is inserted into the annular recessed grooves 58, 62 of the first and second clutch gears 48, 50. Branch

Since the rotational force of the shafts 30, 40 is not transmitted to the clutch gears 48, 50 because it is not connected to the shaft 44, the connecting gear 68 is placed in a stopped state, so that the screw portion 72 of the connecting gear 68 is not
The screw hole 73 is kept connected. After that, the power of the motor 12 is transmitted to the pressing rollers 16 and 17 via the first and second shaft rods 30 and 40, so that the pressing material is pressed by the pressing rollers.

On the contrary, when the housing 18 is separated from the main body 14, the screw portion 72 of the connecting gear 68 is reversely rotated in the screw hole 73 of the housing 18 contrary to the case where the housing 18 is coupled to the main body 14. Must. Further, when the housing 18 is coupled to the main body 14, the connecting gear 68 has a threaded portion 72.
The threaded portion 72 must be rotated in the reverse direction with a force greater than the force with which the screw hole 73 of the housing 18 is coupled. For this,
A second clutch gear 50 coupled to the second shaft 40 rotating at a low speed
Is used. That is, the clutch actuating fork 74 is actuated to mechanically connect the second clutch gear 50 connected to the supporting portion 78 to the second shaft rod 40 so that the rotational force of the second shaft rod 40 causes the second clutch gear 50 to rotate. Is transmitted to the connecting gear 68 via. The connecting gear 68 rotates in the reverse direction, and the screw portion 72 is separated from the screw hole 73 of the housing 18, while the flange coupling surface 19 of the housing 18 is separated from the front surface of the main body 14 to separate the housing 18 from the main body 14.
