Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a squeezing roll used to remove moisture attached to or impregnated on the surface of metal foil, plastic film, textile knitted fabric, etc. It is something.

[Conventional technology]

Conventionally, the squeezing roll 1 has a structure in which a pair of rolls 2 and 3 made of rubber or hydrophilic plastic sponge are brought into contact with each other, as shown in FIG. The rolls 2 and 3 are rotated in the direction of the arrow while pinching the workpiece W such as foil, plastic film, fiber knitted fabric, etc., and the rolls 2 and 3 remove moisture attached to or impregnated on the surface of the workpiece W. Wipe it off or squeeze it out.

[Problem that the invention attempts to solve]

However, the workpiece W tends to get entangled with the roll 2 or the roll 3 due to moisture, as shown in FIG. 6, which poses a serious hindrance to continuous and smooth drawing work.

[Means for solving problems]

The present invention provides a means for solving the above-mentioned conventional problems by providing a pair of rolls 2, 2A, 2B, 3, 3 rotatably supported by machine frames 8, 8 and pressed against each other.
Peripheral grooves 6, 6A, 6B, 7, on both side edges of A, 3B.
7A and 7B are provided respectively, and the pair of rolls 2, 2 are provided.
Two sets of left and right thin wires 11, 11, 12, 12 are passed between the front side and the rear side of A, 2B, 3, 3A, 3B, and the left and right pair of thin wires 11, 11A, 1
1B, 12, 12A, 12B are the circumferential grooves 6, 6 of the pair of rolls 2, 2A, 2B, 3, 3A, 3B.
A, 6B, 7, 7A, 7B roll 2, 2A, 2
B, 3, 3A, and 3B are provided with squeezing rolls that bite into the contact sides, respectively.

[Effect]

The function of the present invention is as follows.

When the workpiece W is rotated while being pinched between a pair of rolls, the workpiece W is moved in the direction of rotation of the rolls 2 and 3 while removing moisture. Even if the workpiece W tries to get caught in either of the pair of rolls, it will not be able to get tangled because it is obstructed by the thin wire extending between the front and rear sides of the pair of rolls. Since the thin wire bites into the circumferential groove of the roll, the thin wire does not come into contact with the workpiece W at the position where it is pinched between the pair of rolls.

[Effect of idea]

Therefore, in the present invention, the work W can be smoothly drawn without getting entangled with the rolls.

〔Example〕

The present invention will be explained with reference to an embodiment shown in Figs. Rotating shafts 4 and 5 of the rolls 2 and 3 are supported by machine frames 8 and 8. the pair of rolls 2,
3 is made of a hydrophilic sponge made of rubber or soft plastic, and has circumferential grooves 6 on both side edges, respectively.
6, 7, 7 are provided. The circumferential groove 6, 6,
Metal wires 11, 11, 12, 12 bite into the rolls 2, 3 on the contact sides of the rolls 2, 3, respectively, and both ends of the metal wires 11, 11, 12, 12 are inserted into the rolls 2, 7, respectively.
3, the machine frames 8 and 8 are installed on the front and rear sides respectively.
Support rods 13, 13, 14, 14 that are passed to
It is attached to. Both ends of the rotating shaft 4 of the roll 2 are pressed by a spring 10 via a screw 9, and by adjusting the elasticity of the spring 10 with the screw 9, the pressing force between the rolls 2 and 3 is adjusted.

In the above configuration, for example, when the workpiece W is sent between the rolls 2 and 3 rotating in the direction of the arrow in FIG. The work W is wiped by rolls 2 and 3, but the workpiece W is wiped by rolls 2 and 3.
When it comes out of the roll, it tends to get stuck in either of the rolls 2 or 3 due to the wet level of moisture. However, as shown in FIG.
Unable to escape from being blocked by 2.

FIG. 3 shows another embodiment of the invention. In this embodiment, the rotating shafts 4A, 4B, 5A, 5B
A pair of rolls 2A, 2B, 3A, 3 supported by
A pair of squeezing rolls 1A, 1B consisting of B are arranged in front and behind, and the circumferential grooves 6A, 7A of the rolls 2A, 3A
One metal wire 11, 11, 12, 12 is stretched across the circumferential grooves 6B, 7B of the rolls 2B, 3B, respectively.

Still other embodiments are shown in FIGS. 4 and 5. In this embodiment, the rotating shafts 4A, 4B,
A pair of rolls 2A, 2 supported by 5A, 5B
A pair of squeezing rolls 1A consisting of B, 3A, 3B,
1B are arranged in the front and rear, and the circumferential grooves 6A, 7A of the rolls 2A, 3A and the circumferential grooves 6B, 7B of the rolls 2B, 3B.
The metal wires 11A, 11A, 11 that bite into the
B, 11B, 12A, 12A, 12B, and 12B are stretched. And the circumferential groove 6 of rolls 2A, 3A
A, 7A and the circumferential grooves 6B, 7B of the rolls 2B, 3B are out of position as shown in FIG. By doing this, the circumferential grooves 6A, 7A, 6 are formed on the surface of the workpiece W.
Almost no traces of B and 7B remain.
