SU623800A1 - Long material tension regulator - Google Patents

Description

The isotropic section of the field of hexagon engineering, in terms of devices for adjusting the tension of pin-dimensional material.

The PiGBocTHO device for controlling the tension of the material arniiiHOMOpiioro, which contains the stabilizers, one for the other direction of movement of the magiercal two directions 1, their roller, kine: matched to each other, and the tension sensor to; material ij.

This device for tensioning a thread-like material at different tensions creates excesses of both signs, which leads to the breaking of high modulus bocons. Reducing the wrap angle of the pr1shodg to reduce the likelihood of material slipping; no slippage regulator.

The aim of the invention is to provide a stable tension for high modulus materials.

For this purpose, the preferred device has a means of moving:; wired from the rollers in the direction of movement of the material, associated with the sensor.

; One is in the form of an electromagnetic clutch, and the dimensions of the vapic and the distance between them are related to the following day.

Claims (3)

The drawing shows the proposed device. ; The tension adjustment device of the dinnier 1 contains two guide rollers 2 and 3 installed one after the other in the direction of the material chasing and the two rigid rollers 4 are connected. The roller 2 has a tool of the center 5 of moving it in the direction of movement of the material 1, made in the form of a screw pair and drive 6. Means 5 for moving the roller 2 is associated with a tension sensor | made in the form of an electromagnetic coupling 7.; Spring-loaded truck elements 8 and 9 days for the elimination of slippage consist of two rollers made of a ductile material, such as rubber, polyurethane, connected by a spring 11, and a clamping element 12 to change the pressure on the material, while noag | The cargo truck element 9 is mounted in a housing that can move from in the guides. The device works as follows. The lengthy material 1 is packed onto rollers 2 and 3 and pressed with spring-loaded track elements 8 and 9. By installing the calculated center-to-center distance determined from formulas (1 and 2), by moving the roller 1 in the guides, the required degree of OTHO stress is achieved. / TZ (and, then - the degree of tension; the radii of the rollers, TJ - Fri. Where C- | is the length of the feed material; is the length of the outgoing curved material; 1 is the gear ratio; LI is the center-to-center distance, mm. During operation devices material 1, moved along rollers 2 and 3, obtains the set degree of tension. When the degree of tension changes, the electromagnetic clutch 7 delivers a mismatch signal to the actuator 6, which is set in motion. The required degree of tension is achieved by automatic adjustment. The use of spring-loaded track elements 8 and 9 and the adjustment of the tension level a change in the center-to-center distance reduces the likelihood of slippage and bending of a long-fibrous high-modulus material, stabilizes and more accurately adjusts the degree of tension teriala. Claim 1. A device for controlling the tension of a lengthy material containing one after another in the direction of movement of the material two directions of the roller, kinematically interconnected, and a material tension sensor, which is In order to ensure a stable tension of the material, it has the means to move one of the rollers in the direction of movement of the material, associated with a tension sensor made in the form of an electromagnetic clutch, and the dimensions of the rollers and the distance between them The following ratios: p- .- (- L LV T, / where is the degree of required tension,, T, are the radii of the rollers, defined by the formulas: n. 2TG1 21G where c is the length of the material supplied to the device, - the length of the material released from the device; 1 is the gear ratio; and L is the center-to-center distance. 2. The device according to claim 1, wherein the moving means of the roller is a drive screw pair. 3. The device according to claim 1, wherein it has clamping spring-loaded rollers, each of which is installed with the possibility of contact with the surface of the guide roller.
