Abstract

The invention relates to equipment for processing leather raw materials and can be used in units of continuous dyeing of leather. The goal is to increase the cleaning efficiency. A device for cleaning a string conveyor includes a bath 1 with U-shaped removable partitions (P) 2 in which anti-adhesive substance 3 is placed, for example industrial oil. The invention relates to leather processing equipment and can be used in skin coating dye units. The aim of the invention is to increase the cleaning efficiency. Fig. 1 shows the device tB in the working position, general view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 shows the initial state of the device when charging strings; figure 4 is a diagram of the installation of the device on the equipment, and the cleaning body. The latter is made in the form of scrapers 4 placed between P 2 and made of a material capable of absorbing an anti-adhesive substance, for example, of felt. The bath has an adjustable frame 6, on which plates 7, made of felt, are fastened. In the contact zone of the strings 8 of the conveyor with scrapers 4 and plates /, a thin layer of anti-adhesive substance 3 is applied to the surface of the strings. In the color chamber, when coating is applied to the skin, a part of the paint falls on the strings 8 of the conveyor. Drying on the skin and strings 8, the paint forms a film. The skin is then removed and the strings are moved to the area of the string cleaner. The paint film is easily removed from the strings in the contact zone with the scrapers 4 and the plates 7 and will fall on the U-shaped P 2, which are paint accumulators. 1 hp f-ly, 4 ill. A device for cleaning a string conveyor consists of a bath 1 with U-shaped removable partitions 2 in which an anti-adhesive substance 3, for example industrial oil, is placed, and a cleaning body in the form of scrapers 4 made of a material capable of absorbing an anti-adhesive substance, for example, from felt.

Description

conveyor strings 8 move. The frame 6, by means of the handle 9, is able to move up and fixed by the stop 10.

FIG. Figure 4 shows the installation of a string cleaning device 11, for example, on a coating dyeing and skin drying unit, which consists of a rotary conveyor, on which the skin 12, the coloring chamber 13 and the drying chamber 14 are placed for processing.

The device works as follows.

In the cover coat operation J, the skin 12 is laid on a moving string conveyor, the strings 8 of which are in constant contact with the scrapers 4 laid in the bath 1 and the plates 7, 2 fixed to the frame 6, and the scrapers tend to absorb the anti-adhesive substance 3.

In the contact zone of the strings 8 of the conveyor with the scrapers 4 and the plates 7, a thin layer of anti-adhesive substance 3 is applied to the surface of the strings. In the coloring chamber 13, when coating is applied to the skin 12, a part of the paint falls on the strings 8 of the conveyor, drying drying on the skin 12 and the strings 8 of the conveyor and forming a film.

After drying, the skin 12 is removed from the string conveyor, and the strings 8 with an applied film of paint are moved to the area of the device 11 for cleaning the strings. Paint film having a low ad3

heziyu with the surface of the strings, easily removed in the zone of contact with scrapers and plates and falls on the U-shaped partitions 2, which are paint accumulators. When replacing the strings 8 of the conveyor (Fig. 3), the frame 6 by means of the handle 9 is moved upwards and fixed by the stop 10.

This device allows to improve the quality of cleaning the string conveyor from paint residues and increase the service life of the string conveyor by reducing string wear.
