Description

[Detailed explanation of the invention] A continuous adhesive press machine, for example, polymerizes the outer fabric and the backing material with adhesive, feeds them between the upper and lower conveyor belts, and presses and bonds them with upper and lower pressure rollers while heating them. It is used to make adhesive products continuously.

During pressure bonding, when bonding soft cotton fabric and backing material, applying strong pressure will cause them to collapse, while applying weak pressure will result in weak adhesion. It was necessary to adjust the pressurizing force each time.

However, the conventional continuous adhesive press disclosed in Japanese Utility Model Application Publication No. 56-31527 can adjust the pressure of the feed roller and conveyor belt, but the pressure of the pressure roller, which is the most important part of a press, cannot be adjusted. Because it cannot do this, it cannot be called a perfect continuous adhesive press.

The present invention solves these drawbacks by providing a continuous adhesive press machine that can easily adjust the pressing force of the feed roller, conveyor belt, and pressure roller so that a desired thickness of adhesive product can be produced depending on the adhesive material. The configuration of the pressure adjustment device will be described in detail with reference to the accompanying drawings as follows.

A lower feed roller 2 and a lower pressure roller 3 are provided at the left and right ends of the machine base 1, and a lower conveyor belt 4 is suspended between the lower feed roller 2 and the lower pressure roller 3.

An upper feed roller 5 is disposed opposite to the lower feed roller 2, an upper pressure roller 6 is disposed opposite to the lower pressure roller 3, and an upper conveyor belt 7 is disposed between the upper feed roller 5 and the upper pressure roller 6. to be suspended.

The lower conveyor belt 4 and the upper conveyor belt 7 are preferably made of glass fiber woven fabric and have Teflon-treated belt surfaces to prevent adhesive from adhering to them.

Lower heater plates 8 are provided at regular intervals on the lower surface of the pressure-side belt of the lower conveyor belt 4 between the lower feed roller 2 and the lower pressure roller 3.

In correspondence with the lower heater plates 8, upper heater plates 9 are provided at regular intervals on the upper surface of the pressure-side belt of the upper conveyor belt 7.

In the drawing, the lower heater plate 8 and the upper heater plate 9 are shown arranged vertically and alternately in parallel.

In such a continuous adhesive press machine, a feed roller gap adjustment mechanism a is provided for adjusting the contact gap between the lower feed roller 2 and the upper feed roller 5.
and a belt gap adjustment mechanism b that adjusts the contact gap between the lower conveyor belt 4 and the upper conveyor belt 7.
A pressure roller gap adjustment mechanism c for adjusting the contact gap between the lower pressure roller 3 and the upper pressure roller 6 is provided at an appropriate location on the machine base 1, machine frame, or the like.

In the feed roller gap adjustment mechanism a shown in the drawing, the middle part of a connecting plate 12 is mounted on both ends of a shaft 11 installed between machine side plates 10, and the upper feed roller 5 is mounted between one end of the connecting plate 12. , a rod 14 of an air cylinder 13 (a hydraulic cylinder may be used) provided on the outside of the machine side plate 10 is attached between the other end of the upper feed roller 5, and the upper feed roller 5 is brought into contact with the lower feed roller 2. The figure shows a case in which they are provided so that they can be freely separated.

The air cylinder 13 is shown equipped with a stroke adjustment mechanism 15 that can adjust the stroke of the rod 14.

The belt gap adjustment mechanism b in the drawing has racks 16 vertically disposed below both ends of each upper heater plate 9, and a pinion 18 of a pinion shaft 17 provided parallel to the inside of the machine side plate 10 meshes with the rack 16. A worm wheel 19 is provided at one end of the pinion shaft 17, a worm gear 21 of a worm shaft 20 mounted between machine side plates 10 is engaged with the worm wheel 19, and the worm shaft 20 is rotated via a handle 22. A case is shown in which the upper heater plate 9 is provided so as to be able to move toward and away from the lower heater plate 8.

The pressure roller gap adjustment mechanism c in the drawing has the same structure as the feed roller gap adjustment mechanism a, and the connecting plate 1
The figure shows a case in which the lower pressure roller 3 is mounted between the other ends of the rollers 2 and 3, and the lower pressure roller 3 is provided so as to be movable toward and away from the upper pressure roller 6.

The drawing also shows a cooling mechanism for removing adhesive, dust, thread waste, cotton waste, etc. adhering to the lower conveyor belt 4 and upper conveyor belt 7 above and below the feed side of the lower pressure roller 3 and the upper pressure roller 6. It is set up. (A rolled tape 23 impregnated or coated with a cleaning agent such as silicone liquid is pressed against the belt surface via a pressure roller 24.) In the figure, 25 is a lower wrinkle removing roller, 26 is a wrinkle removing roller, 27 is a heater guide rod, and 28 is its guide plate.

Since the present invention is configured as described above, when the polymer member 29, which is made by polymerizing the outer fabric and the back interlining, is fed from the feed side of the lower conveyor belt 4 and the upper conveyor belt 7, between the lower conveyor belt 4 and the upper conveyor belt 7. When passing through, it is heated by the lower heater plate 8 and the upper heater plate 9, and the adhesive on the back interlining side is melted.

When passing between the lower pressure roller 3 and the upper pressure roller 6, this overlapping member 29 is bonded under pressure and is continuously sent out from the delivery side as a bonded product.

During this pressure bonding, the lower feed roller 2
The contact gap between the belt and the upper feed roller 5, the belt contact gap between the lower conveyor belt 4 and the upper conveyor belt 7, and the contact gap between the lower pressure roller 3 and the upper pressure roller 6 must all be adjusted. If this happens, perfect pressure adjustment will not be possible.

In this regard, in the present invention, the contact gap between the lower feed roller 2 and the upper feed roller 5 is adjusted by the feed roller gap adjustment mechanism a, and the belt contact gap between the lower conveyor belt 4 and the upper conveyor belt 7 is adjusted by the belt gap adjustment mechanism b. Since the contact gap between the lower pressure roller 3 and the upper pressure roller 6 can be adjusted to a desired pressure by the pressure roller gap adjustment mechanism c, the lower feed roller 2, the upper feed roller 5, and the lower conveyor, respectively. By adjusting the contact gaps between the belt 4 and the upper conveyor belt 7, and between the lower pressure roller 3 and the upper pressure roller 6, even in the case of pressure bonding of cotton fabrics, it is possible to achieve a soft and fluffy surface that will not collapse even when pressure bonding is performed on cotton fabrics. It is possible to make thick adhesive products.

As described above, the present invention makes it possible to adjust the pressure of the lower pressure roller 3 and the upper pressure roller 6, so that the desired thickness can be achieved by simply feeding the polymeric member between the upper and lower conveyor belts. To provide an excellent pressure adjustment device for a continuous adhesive press machine that can continuously produce adhesive products.
