Description

Devices are known that are made in the form of chambers with a chain conveyor and looper for drying various belts and roll materials. Installations for the processing of tape materials are also known, including conveyor rollers, a bobbin holder and pre-heat treatment and finishing chambers.

Also known is the use of thermal radiators and squeezing drums in such devices. However, the known installation has its drawbacks, reducing their performance.

The proposed apparatus for treating a shuffling film in the manufacture of triplex is more sophisticated and productive than the known ones; It is a conveyor on which the film in rolls is prepared for its further use in the production of laminated glass (triplex).

The installation conveyor is divided into sections and chambers in which the following operations are performed: dry cleaning, wet cleaning, rinsing with distilled water, pressing water and pre-drying with infrared thermal radiation, as well as a final drying section using Air conditioning at 25 ° C.

The peculiarity of the proposed installation for the processing of the dummy film is the operation of gluing the tape, for which a table with a horizontal plate is installed in front of the dry-cleaning chamber; The usefulness of the proposed installation is marked by GIS. The schematic drawing 1 shows the proposed installation consisting of a conveyor divided into sections and chambers in which the following components are located: a coil holder with a roll /, a device 2 for gluing a film consisting of a table - a cast-iron polished plate, where the iron presses the film; dry cleaning chamber 5 with a rotating brush; transporting rollers 4; carame no. 137257-2-pap wet cleaning 5 with brushes to which water is supplied; pre-drying chamber 6 with a squeeze drum 7 and infrared thermal radiation 8; loop dryer 9 for final tape drying.

The technological process of processing a boot film consists of the following operations. On the open frame, grippers are installed — the centers at which the unwinding film roll is clamped. Next on the film is a table for gluing film. The gluing process is carried out in the following order: the end of the unwound roll to the full width of the film and 2-3 cm in length is rubbed with alcohol, and thus the beginning of the next roll is prepared. Then, the beginning and the end are folded over the plate and pressed with the iron with the help of a pedal. At the end of the gluing, the iron is lifted from the film by the lever. The glued tape enters the dry cleaning chamber, where rotating hair or nylon brushes sweep sodium bicarbonate, first on one side, then on the other side of the film. After dry cleaning, the tape enters the wet cleaning chamber, where it passes through four pairs of brushes, under which water is supplied with a temperature of 15-18 ° at the beginning and 40-45 ° at the end of the operation.

Next, the washed brush is rinsed with distilled water at a temperature of 40-45 °. The final section of the path in the wet-cleaning chamber is a film that rises at an angle of 10 ° so that the water rolls off the film.

The pre-drying chamber removes the surface layer of water using felt rollers wrapped in a web. The drying process is carried out by adjusting the temperature and the preliminary deep drying of the film is achieved by infrared rays using thermal radiators.

The transportation of the film is carried out with the help of paired rubber rollers, which allow a change in the speed of transportation with the help of a reducer and interchangeable bristles. This drive also drives the cj / gears with the looper where the film comes from the pre-thread. In the dryer with a looper on two main chains, hung cross-beams covered with polyethylene. The formation of film loops, posted on the vesicles, occurs due to the slower movement of the main chains than the film moves. Slow-moving loops along the chamber are blown with conditioned air with a temperature of 25-28 ° C and a humidity of 25%.

In order that at the time of forming the loop there was no breakthrough of the film on the hangers, a fan nozzle was installed in the place where the loop was formed, through which the air holding the film was supplied. There are also special rubber cords that hold the film to the first one. After drying, the prepared film is transferred for recycling.

Subject invention

An installation for processing a foil film in the production of triplex, including a bobbin holder, dry and wet chambers, transport rollers, a dryer with squeezing drums and infrared radiators for pre-drying and a loop dryer for final drying, so as to perform the operation gluing the tape, in front of the dry-cleaning chamber, a table is installed with a plate above which a movable electric iron is mounted on the rotary lever, interacting with a spring-loaded control pedal.
