Description

The invention relates to the manufacture of rubber technical products and can be used to make endless rubber reinforced tapes.

The purpose of the invention is to simplify the design of the device.

Figure 1 schematically shows the proposed device for assembling endless rubber bands; ia 2, - section aa in figure 1; 3 - positioning of the cord on the gummed bushings.

A device for assembling endless rubber bands contains cantilever mounted on the frame 1 drive and tension (not shown) rolls made in the form of sprockets 2, enveloped by an endless roller chain 3. The shaft 4 of the drive roll is connected to the drive 5. On the direction guides 6 of the frame 1 with the possibility of moving along the lead screw 7, a carriage 8 is installed and a slide 10 is mounted on the carriage 8 with the possibility of moving along the guides 9. parallel to the axis of shaft 4 is mounted with the yoke 11 nitevoditelem.12 disposed eccentrically relative to the rotational axis of the cage. The yoke 11 has an outer rim 13. To move half-. There is an additional spindle 14. and an additional shaft 15. There is an additional spindle 14 kinematically connected to the additional shaft 15 by means of a straight shaft 16 mounted on the carriage 8 with a long gear wheel 17 and a gear gear 18 engaged with the last gear the rack 19 and the crank mechanism. The connecting rod 20 of the latter is connected to the gear rack 19, and the crank 21 through the gear transmission 22 with an additional shaft 15.

-. i The long gear 14 through the gear 23 is kinematically connected to the additional lead screw 15, and through the gear 24 with the gear casing 13 of the cage.

The additional shaft 15 is connected via a gear transmission 25 to the lead screw 7, and by means of a gear transmission 26 and a shaft 4. A braked bobbin holder 27 is fixed to the slider 10. The device operates as follows.

 In the bushings of chain 3, rods 23 are mounted on which gummed bushings 29 are placed, which are the fittings of the assembled rubber cable.

When the drive 5 is turned on, movement is communicated to the drive sprocket 2, which carries the chain 3 with the bushings 29. At the same time, the rotational movement through

the gear transmission 26 is transmitted to the additional drive shaft 15 and through the gear transmission 25 to the additional lead screw 7 - the carriage 8.

When the shaft 15 rotates, the crank 21 rotates, together through the connecting rod 20, the reciprocating motion of the gear rack 19, which is converted into the reciprocating motion of the intermediate shaft 16, from the shaft 16 through the gear

23, the spindle 14 is rotated, which reciprocates along the guides 9 of the slider 10. At the same time, 11 is driven back and forth through gear 24.

In this case, the gear ratios of the gears 18, 17, 23 and 24 are selected so that during the course of the rack 19 from top dead center to bottom dead center

the holder 11 rotated in one direction, and when the rack 19 is moving in the opposite direction by. same angle to the other side. The slider 10 at this time is shifted by the stroke to the left (in Fig. 1) or to the right, providing the cord 30 to be wound on the bushings 29 along a predetermined path (Fig. 3).

All this time, the carriage 8 continues to continuously and uniformly move along the guides 6 of the bed 1, due to which, for

a complete revolution of chain 3, cord 30 is wound around a pitch (Fig. 4).

After winding the cord, an elastomer is applied, bushings 29 are disconnected from chain 3, and the assembled tape is on.

cured by vulcanization.

The proposed device allows

expand functionality

devices by enabling automatic winding

cord around the reinforcing elements, the cord being wound in such a way that the cord covers one reinforcing element on one side and the adjacent one on the opposite side, which leads to improvement. operating conditions. endless rubber reinforced tape by increasing the longitudinal flexibility of the tape.
