Abstract

The invention relates to the manufacture of rubber products, to the cutting of the ends of rubber cable conveyor belts before joining. The goal is to improve the quality of the cut ends by eliminating the damage to the cables. To do this, when removing the plates, the tape is freely placed on the transverse supports with the possibility of deflection between them, and the tool is placed on the opposite side of the supports. Cutting the inter-strip gaskets is done before the bottom plate is removed when the tape is bent with the treated side facing the tool in the transverse direction of the cables. The cutting is carried out to a depth of at least the diameter of the cables. 3 il.

Description

The invention relates to the production of rubber products, in particular to methods of joining rubber cable conveyor belts used in the transportation of rock mass at mining and coal enterprises.

The aim of the invention is to improve the quality of the ends to be cut by eliminating damage to the cables.

FIG. 1 shows the removal of the upper plate; in FIG. 2 shows the cutting of inter-channel gaskets in FIG. 3 - remove the bottom plate.

The method is carried out as follows.

Tool 6 (Mill) is installed between the supports to remove the lining, after which the belt is moved along the cutting edge of the end cutting length (Fig. 1 In the rubber milling process, a repulsive tape arises a force that bends it between the rollers, overcoming the carcass stiffness. The rubber milling force is many times smaller than the steel milling force, and therefore the repulsive tape

The force grows many times as soon as the milling cutter begins to cut the steel frame. In this case, the tape will be propelled away from the tool. Thus, the skeleton is automatically protected from damage, reflecting positively on the quality of the butt splitting.

After removing the upper facing of the KONEC tape, they are bent with the milled surface outwards (Fig 2) and along the cables on either side of them, they make cuts 7 with knife blades 8 to a depth not less than the diameter of the cables. Due to the fact that when the tape is bent, its outer layer is stretched, the cutting force of the rubber and the force of the steel knife against the rubber are significantly reduced. In this case, it is advisable to use a two-blade design of knives, which are inserted into rubber and swept along the cables as if they were guides.

Since, while moving along the cable, the knife copies its route, the quality of the separation is not affected by the deviation of the cable route from its design position, which in practice occurs quite often. Shallow inter-cut rubber cuts require less energy than cutting through the gasket and the lower lining of the tape, and the knives do not stick between the cables.

The final operation is the Zero lower plate facing, for which the treated end of the tape is straightened and placed between the upper supports 9 and the lower cutter 10 The tape is fed along arrow B, including the Mill, which is Spin upwards, the end being worked

tape, due to the rigidity of the frame cuts off the bottom plate without damaging the cables. Since the rubber gaskets had already been cut between the cables to the depth of their diameter, after removing the bottom plate, split cables in the sheath 11 and strips 12 gaskets, which have a square (rectangle) shape in cross section, come out from under the cutter. The strips are removed and the rubber-wrapped cables are ready to dock the ends of the tape.

Thus, the method of cutting the ends of rubber cable conveyor belts is simple, fully mechanized, and provides the required quality of the docking.
