SU28315A1 - A device for rotating frames with molds in the manufacture, by dipping, of rubber products without seam by the conveyor method - Google Patents

Description

In the manufacture, by dipping, of rubber products, without a seam by a conveyor method, a device is proposed for rotating frames with molds moved by a conveyor chain, in which an auxiliary chain intermittently rotated from a common drive and mounted on fixed gears located next to this chain conveyor chain rollers. To ensure that both chains adhere to each other, in places where the conveyor chain is bent, it is proposed to place guides with a T-groove on the auxiliary chain to enter the elongated ends of the chain spigots and guide its grooved rollers.

In FIG. 1 depicts a makii chamber of a common conveyor belt in a longitudinal section; FIG. 2 is a diagram of gears to chains in a conveyor machine (the view in Fig. 1 on the right); 3,4,5- three projections of the part of the device in the place of the bend of the conveyor chain in the magnified relation to FIG. 1 and 2 scale; FIG. 6 is a separate projection of the angular guideline; an auxiliary chain is a view of the direction of the chain from the inside.

Two endless chains 1-1 (fig. 1-5) of the conveyor machine are carried by rollers 2,

to which are attached frames 3 with forms 4, which serve for periodically dipping them into rubber glue, for drying and other operations of the process of manufacturing products. The drawings show a portion of a conveyor machine, serving for the operation and drying. Frames 3 with forms 4 between two adjacent dips get double movement: periodically available to feed each frame to the box with glue and rotary to dry the soaked forms, in order to properly wrap the adhesive along the forms evenly along the entire length of them. Periodically translational movement of the chains 1 - 1 in the vertical and horizontal planes is communicated from the continuous-rotating camshaft 5 (Fig. 2) and the toothed sector b using gears 7.

The shaft 5 receives the rotation from the drive belt pulley 8 through a complex gear train 9-13.

For the transfer to uniform-rotating frames 3 with forms 4, an auxiliary chain 14 is used, which is parallel and close to the main chain, which engages with gears 15 mounted on rollers 2. Chain 14 receives periodic movement from

the same camshaft 5, toothed sector b and gears 9-13.

The toothed wheels 16, 17, 18 (Fig. 2) and, consequently, the chains: the main 1-1 and the auxiliary 14 move alternately, i.e., when the main chain is stationary, then the forms are drying in order (except for the forms directly above the boxes with glue) are rotated by gears 15, sitting on rollers 2, and an auxiliary chain 14. When the main chain 1-1 is moved, the auxiliary chain is in place, but the teeth 15 roll along the chain 14 and rotate the forms . To couple the gears 15 to the auxiliary chain 14 at the points of bending of the main chain, the auxiliary chain has elongated rollers 19 (Figs. 3 and 4) and passes upward along the stepped gears 20 with a smooth middle groove, enabling the gears 15 to engage the chain 14, and below - through the box 21 with a stepped profile 22, also contributing to the coupling of the chain with the gear.

Molds that are not above the glue box can also rotate in this case, since shaft 5 remains connected to the gear and will rotate the auxiliary circuit.

The process of ensuring that the rotation of the forms does not cease when the main circuit is accidentally stopped, a second gear is arranged to rotate the auxiliary circuit 14, which only works during the time of these random stops.

The subject matter of the invention.
