Description

one

The invention relates to devices for impregnating a moving tape material of unlimited length by immersing it in a flowable substance, for example for impregnating paper with carbide resins, and can be used in the woodworking, furniture and other industries.

A device for impregnating a web material is known, comprising a bath for an impregnating liquid and a roller system 1.

The disadvantage of such a device is its complicated constructive implementation.

Closest to the described invention is a device for impregnating a coiled material, comprising a device for unwinding a coiled material, an impregnating device, a drying chamber, a cooling section, driven shafts and a centering device with leading and driven shafts 2.

The disadvantage of this setup is the need to manually feed the web of material being processed into the roll system, which reduces its productivity.

The aim of the invention is to increase plant productivity by mechanizing the charging of the web material.

This goal is achieved in that the installation for impregnating the rolled material, comprising a device for unwinding the rolled material, the impregnating device, the drying chamber, the cooling section, the driven shafts and the centering device with the driving and driven shafts, is provided with a tension element having a grip and tension on sprockets, which are mounted with the possibility of free rotation at the ends of each driven shaft, and the driving mechanism of the tensioning element connected to the drive shaft of the centering device, the drive mechanism of the tensioning element is designed as a freely mounted at the ends of the driving shaft centering device Stars with brake drums and brake pads, mounted at the ends of the driving shaft of the centering device, and the tensioning member is a chain.

FIG. 1 shows a schematic of the installation; in fig. 2 shows section A-A in FIG. one.

The installation comprises a device 1 for unwinding a web material, an impregnating device 2, a drying chamber 3, a cooling section 4, a system of driven shafts 5, a centering device b, on.

The dead element 7 in the form of a chain, clamps 8, installed instead of a link in the chain, sprockets 9. The centering device 6 consists of a drive shaft 10 and a driven shaft 11. The sprockets 9 are worn symmetrically with the possibility of free rotation at the ends of each driven shaft 5 and the drive shaft 10 centering device. On the drive shaft 10, there is also an tension mechanism for the tension element, including brake drums 12 connected to sprockets 9, and brake pads 13 rigidly connected to the ends of the drive shaft 10. The catch 8 is adjusted along the length of the pin 14. The tension element is stopped by end switches 15.

The installation works as follows.

The tensioning element 7 is tensioned onto the sprockets 9. The web material is attached to the grippers 8. Simultaneously with the launching of the drive shaft 10, the brake pads 13 are engaged, which engage the brake drums 12, thereby driving the sprocket 9. As the sprockets 9 rotate, the movement starts. the tensioning element 7 is carried along by itself unwinding from a roll and a web of material pulling on the shafts. When the edge of the web enters the gap between the shafts 10 and 11 of the centering device 6, the filling process is completed and the tension element 7 is stopped by the limit switch 15, which deactivates the brake pads 13. Rotation from the drive shaft 10 continues. At the time of loading the coiled material, the tension element 7 with the gripper 8 is driven to its original position - to the place of refueling, where its movement is stopped by the second limit switch 15. When the web, paper, for example, or after installing a new web is broken, the web refueling process is repeated and processing tape material pro718176

proceeds with a fixed tension element 7.

The use of the unit allows to mechanize the process of filling the coiled material, improve the working conditions and reduce the number of service personnel.
