Description

[Detailed description of the invention] The purpose of this invention is to provide an embossing renderer with an extremely simple and inexpensive structure that allows for easy mold changes and ensures that the mold fit is maintained at all times. be.

During the operation of an embossing calendar, mold changes are often performed.

Conventionally, in the case of a model with a closed frame structure, the engraving roll and elastic roll were completed and replaced individually facing upwards, and in the case of a model with an open frame structure, the same process was carried out horizontally. Since each bottle must be taken out and replaced individually, it is time consuming and troublesome.

In addition, it is extremely difficult to assemble the parts because it requires skill in order to assemble them accurately and requires precision in the mounting process.

This proposal eliminates all the disadvantages and inconveniences and difficulties of the conventional method at once.

The present invention will be explained with reference to the drawings.

As shown in the first diagram, the present invention consists of a rectangular cassette body 2 having a built-in groove 1 recessed in the front surface into which upper and lower roll bearings can be freely inserted.
and tighten the holes 1 to 3 on the earthen wall 2' of the cassette body 2.
are screwed together in the vertical direction, pass through the screw entry hole 4 in the lower wall 2'', fit the bearing 5' of the engraving roll 5 upwards into this installation groove 1, and tighten it on its upper part. The engraving roll 5 is fixed above the mounting groove 1 by screwing the bolt 3, and then the engraving roll 5 is fixed above the mounting groove 1.
After fitting the bearing 6' of the elastic roll 6 under the cassette and stabilizing it on the groove bottom surface 7 of the installation groove 1 by its own weight, the cassette body cover 8 is placed on the front surface of the installation groove 1, and the upper and lower walls Then, the engraving roll 5 and elastic roll 6 are assembled into the cassette body 2 by screwing with the mounting bolts 9, 9 to create a roll force set (K).

On the other hand, as shown in the second figure, the frame main body 10 is provided with a cassette fitting groove 11 on its front surface in an inclined state in which the above-mentioned roll cassette K can be freely fitted, especially with the upper part inclined inward, and the cassette fitting groove 11 is recessed in the frame main body 10 as shown in the second figure. A cassette fixing screw 12 is screwed into the earthen wall 10' of the groove 11 in a direction along the slope line, and a cassette stator 13 is attached to the lower end thereof, and a downwardly inclined groove bottom 14 is attached to the lower part 10''. It is configured in a planar shape and has an upwardly projecting edge 1 on the front edge of the groove bottom.
5 and a cylinder 17 having a piston 16 is installed inside the lower part 10'', and a piston advancement hole 1B is bored in the center of the groove bottom 14.

Then, as shown in FIG. 3, the roll cassette K is fitted into the inclined fitting groove 11 and the roll force is set by its own weight. The bottom surface 8' of 8 is pressed against the inner surface of the upward projecting edge 15 to stabilize the roll force set) K in the fitting groove 11, and then the fixing screw 12 is inserted as shown in the fourth figure. The roller cassette K is spirally descended and the stator 13 at its tip pressurizes the roll cassette K from the upper surface, and the piston 16 is advanced from below through the entry hole 4 of the entry hole 1B to push up the lower surface of the bearing 6' of the elastic roll. The embossing calender is constructed so that the embossing rolls 5 and 6 are pressed against each other, and the raw fabric P is then inserted between the side rolls 5 and 6 as necessary to operate the embossing calender.

In FIG. 4, a drawing during operation, reference numeral 19 indicates a winding frame 20, and reference numeral 21 indicates a guide roll.

The lower surface 8' of the cassette main body lid has an inclined surface similar to that of the upward projecting edge 15 in order to tightly press against the upward projecting edge 15, and the front and rear surfaces of the bearings 5' and 6' are provided with an inclined surface. The concave groove is vertically provided to improve the contact between the cassette body lid 8 and the power set body 2 for good sliding movement, and the cassette body 2
A vertical protrusion 22 is provided on the back surface of the groove 11, and a vertical groove 23 is provided on the rear surface of the fitting groove 11 to improve vertical sliding due to the fit of both 22 and 23. It is something.

24 is a circular hole formed in the upper surface of the cassette body 2 in order to fit the stator 13, and 25 is a pressure contact plate 2 of the bearing 5'.
Reference numeral 6 denotes a pressure contact plate for the bearing 6'.

Since the present invention is constructed as described above, the roll cassette K in which both the engraving and elastic rolls 5 and 6 are integrated is placed in the frame 1.
After fitting into the inclined fitting groove 11 of a simple construction provided on the front surface of the roller 0, both rolls 5 and 6 are brought into pressure contact by the upper stator 13 and the lower piston 16, and the embossing calendar is operated as it is. I can do it.

Also, in order to change the roll type, if you remove the stator 13 and piston 16 mentioned above, the roll force will be set as they are)
You can take it out and change the model very easily and quickly.

When the roll force set (K) is inserted and installed in the insertion groove 11, the lower front surface of the roll force set (K) is latched by the upwardly projecting edge 15 on the front surface of the groove bottom 14, making the installation stable and easy. It is extremely convenient to do so.

Conventionally, changing the roll shape, which is often done when operating an embossing calendar, requires a great deal of time and effort, as well as skill, as mentioned above, but when doing it as in the present proposal, the time and skill required are significantly reduced. In addition, the present invention has an even more remarkable effect in that it does not require mold fitting at all, although it required mold fitting that was difficult to adjust each time the mold was changed.

The present invention achieves the above-mentioned effects with an extremely simple and inexpensive structure, and therefore has a large moving plate in practice as an embossing renderer.
