(54J DEVICE FOR APPLYING LIQUID COMPOSITIONS

The invention relates to equipment for applying liquid compositions to the surfaces of moving materials, in particular to devices for applying an anti-electrostatic composition to abrasive belts and can be used in the woodworking and other industries.

 A device for applying liquid to the surface of products is known, which comprises a turntable on which a bath with liquid is installed. The squeeze roller, which is rigidly mounted on an axis and partially immersed in a bath of liquid, receives rotation from the electric motor through a conical pair and a gear wheel and consists of large-diameter disks and small-diameter setting disks, which act as supporting sleeves and determine the distance between applied liquid strips 1.

The tape to be processed is installed in the guides and goes down with them until it touches the cylindrical surface of the spreading roller, which rotates continuously, rolls the liquid onto the tape to be processed in even circles, then the tape rises, moves to the desired step, and the work cycle repeats.

However, the known device has a complex structure that does not provide the possibility of adjusting the width of the applied strips. Liquid and requires a significant consumption of the applied composition.

Closer to the invention in its technical essence and effect achieved is a device for applying liquid formulations containing a container with a liquid, a spreading roll partially immersed in it, consisting of depositing discs, wound up pointed at the periphery of a porous deformable material and installed on an axis with a gap between

20 with the help of landing and spacer sleeves, and limiters of the width of the applied strips 2.

In the known device, the limiters of the width of the applied strips are made

25 in the form of restrictive replaceable rigid rollers and installed in the gaps between the deposition discs.

. the disadvantages of the known device is the difficulty of adjusting

30 widths of the applied strips of the liquid, since I measure the width of the applied strips, it is necessary to replace the restrictive replaceable hard rocks, i.e. disassemble the causing shaft and reassemble it. In addition, the disadvantage of the known device is the uneconomical consumption of liquid composition 1 caused by splashing of the liquid composition during rotation of the carrying roll, and when crumpling nanometer discs due to the high tension of the material, the composition can be applied with restrictive replaceable rigid rollers. The aim of the invention is to simplify the process of adjusting the width of the applied strips and saving the overall composition. The goal is achieved by the fact that in a device for applying liquid compositions containing a container with liquid a sublinging roll partially immersed in it, consisting of deposition discs, made circumferentially sharpened from a porous deformable material and mounted on an axis with a gap between them. With the help of landing and spacer sleeves, and limiters for the width of the applied stripes, the limiters for the width of the strip strip are made in the form of mounted above the spreading discs 1 and with the possibility of vertical movement of the support brackets with locking arms the elements on the side walls and a slit for the exit of the working part of the applying disk and a groove in the upper wall. Fig. 1 shows schematically the proposed device for applying liquid formulations; FIG. 2 is a section A-A in FIG. 1; Fig. 3 is a view along arrow B in Fig. 1; The device for compressing liquid compositions comprises a container 1 with a composition of composition 2. The squeeze roller fixed on axis 3 consists of deposition disks 4 of uniform thickness made of porous deformation. material, for example, foam rubber, with a pointed periphery and mounted on axis 3 by means of landing sleeves 5, which play the role of sliding bearings. Between natlos Shch1-MI disks 4 on the axis 3 are installed spacers b. Above the deposition discs 4 are mounted with the possibility of vertical movement of the support bracket 7 with locking elements in the form of screws 8 on the side walls. In the upper wall, the support brackets 7 have a slot 9 for the working part of the deposition disc 4 and the groove 10 for draining excess liquid composition 2, deposited on the support bracket. Chute 10 is positioned in the direction of rotation of the deposition discs 4. Adjusting the width of the applied liquid strips is done by setting the support bracket 7 to a distance equal to a-a / -J from the top of the applying disc 4, where about is the angle at the top of the disc and a is the width applied strip. The device works as follows. The material on which it is necessary to apply the liquid composition 2 moves along the surface of the support brackets 7 and touches the depositing disks 4, which, rotating on the axis 3 with the aid of the seating sleeves 5, are moistened with the liquid composition 2, deformed by the value of b and put the liquid composition 2 on the surface of the material. To adjust the width of the applied strips with liquid compound 2, you need to unscrew the screws S, install the support bracket 7 by the value of b from the top of the applying disk 4, calculated using the formula, and fix it with screws 8. This device has a simpler adjustment system than the first one. the width of the applied strips of the liquid composition, since for this there is no need to disassemble the entire roll, but it is necessary to set the support brackets for a certain distance with screws and slots. The device has a simple construction, is simple to maintain, and has a more economical consumption of the liquid composition, since the support brackets act as reflectors of the spray of the nanbond composition arising during the rotation of the spreading roller, and only the depositing disks are involved in the deposition of the liquid composition. In addition, the support brackets perform the role of guides for the moving material, which improves the technology of applying the liquid composition, and their chute returns the applied surplus of the composition to the container. Formula of the invention A device for applying liquid formulations containing a container with liquid, a spreading roll partially immersed in it, consisting of spreading discs, made circumferentially pointed, made of a porous deformable material and mounted on an axis with a gap between them using landing and spreading sleeves, and limiters., the width of the applied strips, characterized in that, in order to simplify the process of adjusting the width of the applied strips and to save the application composition, the width limiters of the applied strips are as mounted above the application disks with the possibility of vertical movement of the support brackets with locking elements on the side walls and a slit for leaving the working part of the application disk and the groove in the upper wall.
