Description

Devices for drying grinding skins, oilcloths and similar materials are known, including: a closed chain multi-net conveyor with hangers attached to chain links, looping, icing and looping agents.

In these devices, the process cannot be automated, since the hanger cannot take a vertical position and return to its original horizontal position, and to replace the winding core, the conveyor must be stopped.

In the proposed installation, the automation of the technological process is achieved by performing the hanging on the hinges with the possibility of rotation from horizontal to vertical and back. In addition, it is envisaged to use a variable displacement compensator designed to change the winding core without stopping the conveyor.

FIG. 1 shows a general view of the proposed drying unit; in fig. 2 - reciprocating displacing compensator with a device for turning it hung; in fig. 3 - hung structures and sections along aa and bb.

The drying unit for drying grinding cloth, oilcloth, etc. materials consists of a continuous bushing-roller hauling chain (conveyor) / with hinges 2 fixed to it at one end, which are supported by a free condom on supporting rotor 3 to turn it 2 by 90 ° (from horizontal to vertical and vice versa), loopers 5, loopers 6, a reciprocating displacing compensator 7, a winding machine 8 and a speed selector 9.

jYo 136674-- 2 The starting material is fed to the looper 6, installed at the entrance to the drying unit in front of the conveyor 1, and molded into beads. Before applying glue to the material in the machine W, the wire is flattened by the loop dispenser 5, and at the exit of the machine, the wire is molded again.

Drying of the material is carried out on all branches, except the last one, which is designed to return hung 2 to the inlet of the drying unit.

The devices 4 for rotating hung 2 by 90 ° (from horizontal to vertical position and back) are installed in the places of forming and straightening the bells, & also at the outlet of the drying unit, where the device 4 is combined with reciprocating, Ayush, compensator 7. When the winding machine 8 is turned off, the compensator 7 is turned on to change the winding core and moves forward together with the racks 2 for the time required to change the winding core core. When the machine 8 is turned on, the compensator 7 automatically switches the speed selector 9 to reverse. The speed of translational compensation of the compensator is equal to the speed of movement of the conveyor, and the return movement of the compensator occurs 6-7 times slower.
