Abstract

Usage: assembly of endless rubber-cord tapes in the manufacture of drive cord-belts. SUMMARY OF THE INVENTION: A device for assembling endless rubber-band tapes comprises a carriage movable along the spindle with a creel and a thread guide parallel to the drive shaft. It is mounted on the carriage by means of a rotary cracker. A thread guide is installed at one end of the link, and the other end is connected to a crank mounted on the additional shaft of the carriage. 4 ill.

Description

The invention relates to the field of manufacturing rubber technical products and can be used for manufacturing incoming cord belts.

An object of the invention is to enhance the functionality of a device; .

Figure 1 shows a device for assembling endless rubber-cord flaxes; figure 2 is a view along arrow a in figure 1; in Fig.Z - section bB in Fig.2; .4 is a schematic diagram of a backstage with a yarn guide.

A device for assembling endless rubber-band tapes comprises a base 1 with guides 2, on which the carriage 3 is mounted with the possibility of longitudinal movement. In the upper part of the carriage 3 there is a braked bobbin 4 with a cable 5. On the base 1, a drive roll shaft 6 is made, made in the form sprockets 7. covered with tension

roller. 8 with a roller-roller chain 9 with pins 10, on which gummed bushes 11 are mounted, which are the reinforcing elements of the assembled rubber cable. The drive roll shaft 6 is kinematically connected to the shaft 12, also mounted on the base 1. A gear belt pulley 13 is mounted on the shaft 12, connected by a toothed belt 14 to a pulley 15 mounted on the additional shaft 16 of the carriage 3. The carriage 3 is provided with a link 17 mounted on the carriage 3 by means of a rotary cracker 18. One end of the link 17 is kinematically connected to the crank 19 mounted on the additional shaft 16 of the carriage 3 so that it is kinematically connected to the shaft 6 of the drive roll. At the other end of the backstage 17, a yarn guide 20 is installed parallel to the drive shaft with a cable passed through it 5. Parallel to the shafts

6 and 12, on the base 1, a traveling wing 21 of a carriage 3 is mounted kinematically connected to a shaft 6 of a drive stick. The shaft 6 is connected to the rotary drive 22 (conventionally shown),

The device operates as follows,

On the pins 10 vogulno-roller chain 9 wear gummed bushings 11 and fix them about the axial direction. After turning on the drive 22, the shafts 6 and 12, also the lead screw 21, begin to rotate due to their kinematic coupling.

When the shaft 12 is rotated, due to the kinematic SIRL, by means of a gear-driven transmission 13, 14, 15, the additional shaft 16 of the carriage 3 begins to rotate, on which the crank 19 is fixed, which drives the link 17 with the threadblock 20 and the cable 5, which is wound with The bobbin case 4. Occurs on the Mat.Water Gros 5 on the gummed sleeve 11. The thread guide 20 makes one revolution around the gummed sleeve 11 and makes a loop around it. At the same time, the sleeve-roller chain 9 is pulled by an asterisk 7 by one chain pitch and the next gummed sleeve is wrapped. The trajectories of the backstage movement 17 with the thread guide 20, as well as the scheme for winding the cable 15 onto the bushings 11 are shown in Fig. 4. In this way, all the bushings are wound along the helix of the cable

by moving carriage 3 with spindle 21.

Narrow and elongated in the vertical direction (see Fig. 4), the trajectories of the thread guides on the wings allow winding of the fingers with a relatively small step of their location on the chain, i.e. Allows the manufacture of rubber-band tapes with a small tooth pitch.

After completing a predetermined number of Cable Turns around the bushings, the device stops, the workpiece is coated with an elastomer and sent for vulcanization.
