Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sealing device that improves the sealing effect by improving the closeness between the sealing rubber roll and the sealing plate in a high-pressure steamer used for high-pressure moist heat treatment of textile products. .

High-pressure steamers for applying high-temperature, high-pressure saturated steam to textile products such as fabrics and threads to subject them to high-pressure and moist heat treatment are already known. The present inventor has spent a long period of time researching a sealing device for introducing the textile product into the steamer or leading it out of the steamer, and has filed numerous applications regarding the sealing device.

As the latest sealing device that has already been developed, its main structure includes a pair of sealing rubber rolls that are pressed against each other, and an elastic sealing plate that is pressed in the generatrix direction of these sealing rubber rolls and is fixed to a sealing block. However, the most important factor in obtaining a sealing effect in this sealing device is the pressure contact conditions between the sealing rubber roll and the sealing plate.

That is, since the seal plate that is pressed against the seal rubber roll is a metal plate, if the pressure contact between the seal rubber roll and the seal plate is too strong, the surface of the seal rubber roll, which is particularly soft, will wear out, and the gap between the two seal rubber rolls will wear out. Seal effect is lost.

On the other hand, it goes without saying that if the pressing force between the seal rubber roll and the seal plate is too weak, the sealing effect cannot be maintained.

Furthermore, even if the pressure between the seal rubber roll and the seal plate can be properly adjusted before operation, heating during operation (the temperature of the steamer can reaches approximately 150°C) may cause expansion of the seal rubber roll or seal plate. ,
The pressure force between the seal rubber roll and the seal plate is increased, causing problems such as increased wear or rotation of the seal rubber roll.

The present invention has been made to solve such inconveniences, and includes a fixed block fixed to a fabric insertion opening of a high-pressure steamer can through which the fabric can be inserted, and a fixed block provided on the fixed block so as to be openable and closable. In a sealing device having a movable block through which the fabric can be inserted, a pair of seal plates are fixed to the fixed block, and seal rubber rolls that can come into pressure contact with each seal plate are attached to the other movable block via bearings. In addition to rotatably supporting each pair of bearings, the bearing of the corresponding seal rubber roll is fixed to the movable block so that the position can be adjusted in the direction, and the vertical position of the movable block is fixed between the movable block and the fixed block. The present invention proposes a sealing device equipped with an adjustment mechanism, and according to this invention, the pressure force between the sealing rubber roll and the sealing plate can be freely adjusted, thereby achieving effective sealing. At the same time, smooth operation can be achieved.

The present invention will be described in detail below based on embodiments shown in the drawings.

1 is a can body of a high-pressure steamer, and a fabric insertion opening 2 of this can body 1 is provided with a seal block 3 into which a fabric can be inserted.

This seal block 3 consists of a fixed side block 4 fixed to the can body 1, and a movable side block 6 provided on the upper side of the fixed side block via a hinge 5 so as to be openable and closable.

Since the connecting shaft γ of the hinge 5 is loosely fitted into an elongated hole 8 that is elongated in the vertical direction, the movable block 6 can be moved slightly in the vertical direction.

The movable block 6 supports two sealing rubber rolls 9, 9' that are pressed against each other, and in order to support the sealing rubber roll 92g on the movable block 6, the movable block 60 must be supported on both the front and rear sides of the movable block 60. Each pair of front and rear bearings 11 and 11' has a flange 10 extending in the horizontal direction on the edge thereof, and has a concave groove that fits into the flange 10 and is slidable in the direction of the flange.
It is rotatably supported by.

These bearings 11 and 11' can be fixed at desired positions on the collar 10 of the movable block 6 with screws 12.

13 and 13' are wiping rolls that are pressed against the upper sides of the seal rubber rolls 9 and γ, respectively;
, 13' are pivotally supported by a fulcrum 14 at one end of a bearing 15 having a curved side shape and supported by the movable block 6, and the other ends of the bearings 15 are threaded in opposite directions. The threaded rods 16 are engaged with respective threaded portions of the threaded rods 16.

Reference numeral 17 denotes a brush roll that is pressed against the obliquely upper portion of the side surface of the seal rubber rolls 9, 9', and this brush roll is pivotally supported by the movable block 6.

1B and 18' are seal plates having substantially semicircular side surfaces fixed to both sides of the fabric insertion opening 190, which are integrally formed with the stationary block 4, and these seal plates 1B
The seal rubber rolls 9 and γ are brought into pressure contact with each of the seal rubber rolls 9 and γ.

Reference numeral 20 denotes an end seal plate that is joined to the end faces of the seal plates 1B, 18 and the seal rubber roll 9°, and the fabric insertion opening is hermetically closed by these seal rubber rolls, the seal plate, and the end seal plate.

Reference numeral 21 denotes a screw rod that is rotatably supported by the movable block 6. The tip of the screw rod 21 is screwed into the fixed block 4, and a handle 22 is attached to the other end.

The above is an embodiment of the present invention.Next, its operation will be described.By rotating the handle 22, the threaded rod 21 is rotated, whereby the movable block moves vertically relative to the fixed block. For example, if the pressure force between the seal rubber rolls 9, 9' and the seal plates 18, 18' is strong, the movable block can be raised by operating the nozzle 22, and the seal rubber rolls and If the pressure contact force with the seal plate is insufficient, the movable block is lowered by rotating the nodule 22 in the opposite direction, thereby adjusting the pressure contact force between the seal rubber roll and the seal plate to the desired pressure. This can be done easily and quickly, and as a result, an effective seal can be achieved, smooth rotation can be maintained without straining the operation, and adjustment can be made when necessary without stopping the operation.

In addition, the pressure contact force between the seal rubber rolls on both sides is
This can be done by moving and adjusting the parts 1 and 11' along the collar 10.

Furthermore, since the screw rods 21 in this embodiment are arranged at the four corners of the plane, there are great practical benefits such as the ability to adjust the balance.
