Abstract

FIELD OF THE INVENTION The invention relates to the manufacture of rubber products, in particular to the coloring of children's rubber m. The purpose of the invention is to improve the quality of coloring while expanding the color gamut of the applied stripes. For this, the device is provided with at least one additional bath. Baths are installed parallel to each other and each of them is divided by a transverse partition into two compartments. The paint body is made in the form of a pair of paint rollers installed in each bath. Each of the pairs has an individual drive consisting of successively mounted pneumatic cylinders with alternate action. The paint roller is concave made of alternating grooved disks in a specific sequence. The grooves form sharp edges on the concave arc of the roller. The rods of the lower pneumatic cylinders of the roller drives are fixed on the carriage mounted on the frame with the possibility of reciprocating parallel to the axis of the motor shaft. The rods of the upper pneumatic cylinders are equipped with a pair of dampers. 3 hp f-ly, b silt. | SL C

Description

The invention relates to the manufacture of rubber products, namely the coloring of children's rubber m.

The purpose of the invention is to improve the quality of coloring and the expansion of the color range of the applied strips.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 - painting bath with a pair of paint rollers in the working position, side view; in fig. 5 - two baths with partitions and rollers, top view; in fig. 6 - painting roller.

A device for applying strips to baby rubber mites contains a frame 1 with a drive 2, an attachment unit 3, kinematically connected with paint rollers 4 made of alternating disks 5 in alternate sequence, on the radial surface of which there are grooves with a step t 2 mm with the formation of sharp edges, which are located on the concave arc of a given radius. Each groove is made at an apex angle of a ° 45-90 °. The number of lanes and their width depend on the number of disks 5, their thickness and the number of grooves located on their radial surfaces. Paint rollers 4 are mounted for rotation on axis 6 and moving in a vertical plane on axis 7. Disks on paint rollers are made in such a manner as

at the same time so that during their work the strips they cause do not overlap each other. Each pair of paint rollers is lifted, their supply is performed by a corresponding drive consisting of pneumatic cylinders 8 and 9 sequentially installed vertically. Baths 10 are rigidly fixed on the carriage 11 mounted on guides 12 with the possibility of reciprocating movement parallel to the spindle axis 13 of the fastening assembly using a pneumatic cylinder 14, the carriage 11 is equipped with a brake hydraulic cylinder 15. Each bath 10 is divided by a transverse partition 16. The rod of the upper pneumatic cylinder 8 is kinematically connected with a corresponding valve a swarm of paint rollers 4 through the yoke 17, a pair of dampers 18, a couple drove 19. The required force of the pressing rollers to the roller is set by springs 20 of dampers 18. The lower pneumatic cylinder rod 9 is rigidly connected to the carriage 11.

The device works as follows.

The m 21 is mounted in the attachment unit 3, made, for example, in the form of a spindle with a vacuum head driven by the actuator 2. The m h in the vacuum head is held due to the vacuum supplied to it from the vacuum network through the hollow spindle 13. rollers 4 are immersed in a bath 10 with paint. Each compartment of the bath paint a certain color. Compressed air is supplied to the upper cavity of the lower pneumatic cylinder 9 of the first pair of rollers to apply the strips to the meter. In so doing, the housing of the lower pneumatic cylinder 9 and the upper pneumatic cylinder 8 as a whole will be raised. This movement is transmitted to the pair of roller 4 at the same time through the beam 17, the corresponding dampers 18 and the carrier 19. The paint rollers come out of the paint, but do not touch the meter. After a pause, necessary for cutting off excess paint from the side walls of the paint rollers, compressed air is fed into the lower cavity of the upper pneumatic cylinder to further raise the paint rollers 4 and then touch the surface of the ball. In this case, the lifting of the rod of the upper pneumatic cylinder 8 until the moment the rollers touch the ball without compressing the springs 20 of the dampers 18, as shown in FIG. 2. From the moment the paint rollers 4 come into contact with the rotating cylinder 21, the paint rollers begin to rotate.

at the expense of friction. In one revolution of the hour, stripes of two colors are applied. The strips are applied when the grooves of the paint rollers come in contact with the cloth.

After applying the strips on the m of the first

with a pair of rollers, the latter are lowered into the bath with paint, and they are replaced by moving the carriage 11 by means of the pneumatic cylinder 14 and with the help of its drive the second pair is fed

the rollers and the cycle of application of the strips is repeated.
