Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a device for uniformly applying a fluid medium to a 4L body or a strip, optionally via a stencil, comprising a displacement pump device in a discharge channel for the medium. Concerning a form in which the front j is concubined.

In stencil printing machines for textile printing (Iku, and!Samurai), and in machines that apply waterproofing, ink, and adhesives, etc., fluid media are used as a companion.
There is a particular problem, especially when applying to strips. In such cases, it is necessary to keep the pressure applied to the medium to be applied constant during the entire process, while the width of the machine is 5 m.
And since it is buried soil, it is necessary to apply the movable medium as fast as possible. This means that care must be taken to keep the pressure applied to the medium constant over the entire working width and to ensure that the desired amount of fluid medium is always supplied.

In the doctor casing of a stencil printing machine, if the doctor casing has a gear rough opening n in the direction toward the inside of the stencil or the direction toward the strip, the ink is passed through the pump. It is proposed to feed the inside of the doctor casing. However, this type of pump has unavoidable pressure fluctuations that cause markings on the tape surface during the printing operation.

In addition, one method of supplying ink to the doctor is to use an ink container installed at a high position. Based on the height of the liquid level. Such formats result in losses in the ink flow and
At the end of the printing process or when replaced, a considerable amount of ink remains in the doctor and in the supply tube. This is 1

It has also been proposed to provide a pusher pump device within the doctor casing.

The object of the invention is to provide an improved device for uniformly applying a fluid medium.

According to the invention, this problem is solved by
Is the name of the body a belt material? A device for uniformly dispensing a fibrillating medium, in which the displacement pump device has two gear wheels mounted in a floating manner within a casing, these two gear wheels contacting the inner wall of said casing. It was solved by Q that it is configured to be movable up to.

According to the invention, it is possible, for example, to completely and evenly supply a fluid medium over a significantly large working width to the delivery channel for the medium.The gearwheel is arranged in the immediate vicinity of the delivery channel. For example, at the end of the printing process, ink scum is relatively small and becomes a particular problem ('lj:
,',(1) Furthermore, the device according to the present invention has the advantage that it is easy to assemble, works reliably, and is difficult to break down.

Next, the configuration of the present invention will be specifically explained with reference to the embodiments shown in the drawings.

According to FIG. 1, the device according to the invention consists of a casing 1 in which a recess 6'C is provided, in which two gear wheels 3, 4 are arranged. It is located. These gears 3, 4 mesh with each other. These gears 3, 4 are arranged floating or cantilevered in the recess 2. That is, it is movable in the radial direction within the casing. At least one end of at least one of these gears 3.4 is 'J! If
It is connected to a drive system (not shown) with t·W distance in the direction. As you can see in Figure 1, two gears 3 and 4
is in contact with the lower point 5°6 of the inner surface of the notch 2 due to its own weight tC when the operation is stopped.

When the device according to the invention is operated, i.e. at least one of the two gear wheels 3, 4 is driven 5, the gear wheel 3, 4 are rotated in the direction of arrow 8 to force the filled medium into chamber 9. This chamber 9 is formed by a lower part 10 of the inner wall 2 and two gears 3, 4 and 6.
It is limited to 1lJ. A pressure will build up in this chamber 9.

This pressure is shown between point 11 and arrows 12, 13.
．． 4, this gearwheel 3, 4 is pushed until it abuts a point 15, 16 in the upper region of the inner wall 2. The pressing forces are indicated by arrows 17.18.

The lower part of the casing 1 is configured as a one-knot nozzle '19, which has a discharge passage 20 and a discharge opening 21.

The pressure that builds up in chamber 9 also builds up in discharge passage 20 . This pressure is indicated by arrow 14 and discharge passage 20
The flow that exists within! The ith medium is discharged completely uniformly through the discharge opening 21.

By means of a floating or cantilevered gear wheel, the fluid medium is supplied completely uniformly into the pressure chamber, so that a constant pressure is created in this pressure chamber. A constant pressure is transmitted over the entire working width E of the discharged medium. By varying the rotational speed of the two gear wheels 3.4, the pressure and thus the amount of fluid medium discharged can be easily adjusted 6. It is adjusted by

1 and 2, a flowable medium is shown being applied to the strip 23 via the stencil 22. In this case, the strip 23 runs over a counterpressure 24. The stencil 22 is omitted and the fluid medium is distributed [
It can be applied directly or alternatively to other supports, such as plates, zero-port bodies or the like. It is also possible to design the housing 1 itself to be movable or even height-adjustable. This mobility is an arrow;? Ranked 5.

A particularly important point in the present invention is that the inner surface of the casing 1 has a play of 1γ and 5 of the gears 3 and 4, respectively. It is convenient to make the diameter of the cylinder a little larger than the diameter of the gear 3 and 4.

If the fluid medium is one that forms bubbles, the pressure chamber formed by the chamber 9 and the discharge passage 20 can be divided into several chambers as shown in FIGS. 6 and 4. It is best to divide the foam.

This is because, if not handled carefully, the bubble will collapse or its structure will become something else, and it will no longer be able to meet its demands. 3 and 4, a cylindrical chamber 26 is provided in the discharge passage 20. As shown in FIGS.

This chamber 2S completely compensates for the difference in voice volume, so that there will be no problems or irregularities when the foam is applied to a band or support. Not at all. 6 and 4 (1) (the chamber 26 shown has a cylindrical cross-section, but this shape may also be different, and in some cases a smaller chamber of the fluid). may be provided one after the other.The chamber 26 can be approached by either one or both g4II, so that the cleaning device can be removed. chamber 26 and chamber 9 by using an extension.
The connection between the chamber 26 and the outlet can also be cleaned at the same time 1. In many cases, the outlet! ]11 For example, a special VC configuration as shown in FIG. 5 may be used. According to No. 54, side wall 2
7 are provided with grooves 28, so that a series of individual channels with very small cross-sections is formed in the discharge opening 2'1. By providing such grooves, it is possible to make the individual iTh paths completely similar and maintain a predetermined exact spacing.

It is also possible to fit a grooved foil into the discharge opening 21. In this case, separate passages having the shape of )IJ are similarly formed.

In order to close part of the passage and adapt the working width of the device to the requirements, the following measures can be taken.

To close the passage, as shown in FIG.
A slider as Kv29 is provided in the chamber 26.

Since this slider is configured in FIG. 4 as a tube 29 with an opening 30, excess flowable medium flows through the opening 30 and into the tube 29 at a rate of 1.DELTA. This tube 29 is closed on one side and the other 'fl' and 'l' are connected to connections. This allows excess fluid medium to be removed from the device. This is particularly important where the discharge passage is interrupted. If this excess fluid medium is not allowed to drain off, there is a risk that the pressure will build up very quickly, which means
It is inconvenient at the lj location and its ability.

6, 7 and 8 show different embodiments of the running edge of the discharge nozzle.

According to FIG. 6, the discharge opening 21 is located at the rear in the direction of movement of the strip.
The limiting walls are arranged at a predetermined distance from the strip, while the limiting wall in front of the strip in the direction of movement has a spherical tip (C-shaped) and a tape opening. (C is configured to be longer than the rear limiting wall.)

According to No. 7 i7 ttc, the rear limiting wall in the direction of movement of the strip is provided with 31 lips, and according to FIG. 8 an elastic ridge 32 is fixed to the rear limiting wall. The discharge nozzle according to the embodiment of FIG. 6 makes it possible in particular to apply a surface layer.

The invention is not limited only to the illustrated embodiments.

It is therefore also possible to provide a container for the fluid medium 7 outside the casing 1. The two gears do not necessarily have to have the same diameter. Depending on the desired efficiency of the two gears, the teeth of these gears can be selected. The gear teeth for the device according to the invention are relatively dense, but it is also possible to provide significantly finer teeth. As already mentioned, both flat and circular stencils can be used in the mounting according to the invention, so that any flow 7Rb
