Description

[Detailed explanation of the idea] The present invention relates to a cage tensioning device in a seaweed dryer.

In the production of dried seaweed, the seaweed that is made into paper sheets shrinks during drying.

If this shrinkage becomes too large, not only will the standard dimensions as a product not be met, but the quality of the seaweed will deteriorate significantly, such as loss of luster or luster and tearing.

The cause of such shrinkage of seaweed is mainly due to sagging of the screen.

Moreover, when peeling the seaweed, the screen is forcibly pulled, making it even more likely that it will become sagging.

In particular, in the case where a screen is hung between a pair of parallel rod-shaped members, adjustment until the expansion of the screen is stabilized becomes extremely troublesome.

The present invention aims to solve the above-mentioned problem by providing a cage tensioning device for a seaweed dryer that can be easily adjusted to eliminate slack in the cage in the seaweed dryer.

An embodiment of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a dryer body, which has an opening 2 in the front and a pair of parallel endless chains 3 installed inside so that they can rotate intermittently. has been done.

This endless chain 3 has a large number of blades 4 at regular intervals.
The first endless tee 7 is provided near the opening 2.
The screen 6 is passed along with the screen holder 7 between the screen and the screen 5.

The screen 6 is suspended over a screen holder 7 made of a pair of parallel rod-shaped members, and the screen rods forming the screen 6 are provided parallel to the screen holder 7.

The screen holder 7 is formed to be longer than the screen 6, and is horizontally suspended over the first endless chain 5 and the endless chain 3 with shaft portions 8 on both sides.

By the way, on the inner surface of the dryer main body 1, an inner circumferential guide rail 9 and an outer circumferential guide rail 10 for supporting the shaft portion 8 of the screen holder 7 are provided around the endless chain 3.

These guide rails 9 and 10 on the inner and outer peripheries are connected to the dryer main body 1.
The support of the screen holder 7 is cut into a fan shape in order to pass it between the first endless chain 5 and the first endless chain 5 near the opening 2 of the screen.

They each consist of introduction arc portions 9a, 10a, straight line portions 9b, 1ob, turning arc portions 9c, 10c, and derivation arc portions 9d, 10d.

The screen 6 with paper-made seaweed A on the top surface of the screen 6 is inserted between the blades 4 that are opened in a fan shape near the opening 2 of the dryer main body 1 by the first endless chain 5, and by the rotation of the blades 4. Lift up the shaft part 8 of the screen holder 7 and remove the first endless chain 5.
At the same time, it is engaged and supported by the introduction arc portions 9a, 10a of the guide rails 9, 10 on the inner and outer peripheries.

Although not shown in the drawings, auxiliary means for smoothly and reliably carrying out such transfer are introduced arcuate portions 9a and 10a.
and is provided near the derived circular arc portions 9d and 10d.

Reference numeral 11 designates links for connecting both ends of the linear portion 10b of the outer circumferential guide rail 10 to one end of each of the introduction arc portion 10a and the turning arc portion 10c.

The entire inner circumferential guide rail 9 and the introduction arc portion 10a and the turning arc portion 10c of the outer circumferential guide rail 10 are all fixed to the inner surface of the dryer main body 1 via appropriate mounting members 12. Only the straight portion 10b of the guide rail 10 is configured so that the distance between it and the straight portion 9b of the inner guide rail 9 can be increased via the link 11.

That is, the guide rods 13 are vertically fixed on both sides of the straight portion 10a of the outer peripheral guide rail 10, and the guide tube 14 into which the guide rods 13 are slidably fitted is fixed to the inner surface of the dryer main body 1.

Further, one end of the adjustment bolt 15 is fixed to the straight portion 10b, and the bolt 15 is inserted through the top and bottom surfaces of the dryer main body 1 to protrude, and the adjustment bolt 15 is pulled up and down using the nut 16. Make it.

In this way, the straight line portion 10a of the outer guide rail 10 becomes continuous via the link 11, and the distance between it and the straight line portion 9b of the inner guide rail 9 can be adjusted as desired depending on the slackness of the screen 6.

Therefore, the cage holder 7, whose shaft portions 8 at both ends are engaged with and supported by the introduction arc portions 9a, 10a of the guide rails 91, 10 on the inner and outer peripheries, is pushed by the blades 4 while the guide rails 91, 10 are straightened. When passing through portions 9b and 10b, the screen 6 is pulled up and down via the screen holder 7, and is in a tensioned state.

As a result, the sagging of the seaweed 6 is eliminated, and dry air passes smoothly through the gaps between the screens 6. As a result, the nori is dried efficiently, no significant shrinkage occurs in the seaweed, and the seaweed retains its luster and luster, improving its quality. It will get better.

The cage 6 that has been circulating inside the dryer main body 1 is again engaged with the protrusion 5a of the first endless chain 5 from the lead-out circular arc portions 9d and 10d of the guide rails 9 and 10 on the inner and outer peripheries, and is removed from the endless chain 3. The receiver is passed to the first endless chain 5.

The endless chain 5 transports the seaweed to the process of peeling the seaweed.

In the present invention, it is sufficient to configure the guide rails 9 and 10 so that the mutual distance between the straight portions 9b and 10b of the guide rails 9 and 10 on the inner and outer circumferences can be increased.

The introduction arc portions 9a, 10a, the turning arc portions 9c, 1
It is not necessarily necessary to increase or adjust the mutual spacing between 0c or the derived circular arc portion 9d>10d.

This is because not only is the structure more complex, but there are also fewer benefits commensurate with it.

Moreover, the drying of the seaweed is performed while moving along the straight line portions 9b and 10b.

Further, it goes without saying that the adjustment of expanding the mutual spacing between the straight line portions 9b and 10b is not limited to the configuration as in the actual case.

Either or both of the linear portions 9a and 10a of the inner guide rail 9 and the outer guide rail 10 may be configured to be movable up and down.

For example, the two may be connected by a turnbuckle.

According to the present invention, the shrinkage of seaweed during drying can be suppressed as much as possible, and high-quality seaweed that exhibits gloss or luster can be obtained.

Moreover, the drying efficiency of seaweed is improved.
