Abstract
The utility model discloses a variable tension pay-off control device for an optical cable, which comprises a beam tube diameter wheel and an air cylinder; the output shaft of the cylinder is connected with an inserting frame, and the beam tube diameter passing wheel is limited at the front end of the inserting frame through a limiting shaft. According to the utility model, the tension can be controlled by changing the distance between the center of gravity and the supporting shaft only by controlling the pressure of the cylinder through a lever principle.
Description
Technical Field
The utility model relates to the technical field of communication optical cables, in particular to a variable tension pay-off control device for an optical cable.
Background
The quality of the cable depends on the quality of the raw materials used in the production, on the one hand, and on the cabling process, on the other hand. On the premise that the optical cable production materials are the same, the product quality is mainly closely related to the production process, wherein the product quality comprises whether the selection of equipment is proper, whether the design of twisting process parameters is reasonable and the like. For the optical cable, all the components in the structure are twisted, wound, extruded, wrapped and coated layer by layer, the inner layer material is covered by the outer layer material one by one, if the quality problem of the inner cable core is found during the inspection of the finished product, the repair is troublesome, so the control of the cabling process is very necessary.
In order to ensure the excellent performance of the finished optical cable, the control of the paying-off tension of the bundle tube is particularly important in the cabling production. Different tube diameters and different extra lengths of the beam tubes need different tension control. If the tension is not properly set, the excess length of the cable may be unstable, thereby affecting the attenuation of the optical fiber and the mechanical and environmental properties associated with the cable. If the tension of the pay-off stand is inconsistent in the production process, the lengths of the bundle tubes in the cable core are inconsistent, and the whole optical cable is degraded seriously, so that the communication of the whole optical cable is influenced.
Generally, the tube bundle tension control device is a pulley block structure and consists of an upper 5 fixed pulleys and a lower 4 movable pulleys. The action of the cable laying device is to control the laying speed through the moving wheel potentiometer so as to enable the moving wheel potentiometer to automatically track the cable laying production line speed, and the size of the laying tension is adjusted through the balance weight of the balance weight. Because the balance weight swings up and down along with the movable pulley, the position is easy to shift, the tension is changed, and the quality of the optical cable is influenced.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a variable tension pay-off control device for an optical cable, which aims to solve the problem that the quality of the optical cable is influenced because the balance weight swings up and down along with a movable pulley, so that the position is easy to deviate, and the tension is changed.
The variable tension pay-off control device for the optical cable is realized by the following technical scheme: comprises a beam tube diameter wheel and a cylinder;
the output shaft of the cylinder is connected with an inserting frame, and the beam tube diameter passing wheel is limited at the front end of the inserting frame through a limiting shaft.
As preferred technical scheme, be fixed with the balancing weight on the cylinder, and insert the link one side of frame and install the back shaft.
As a preferred technical scheme, a beam tube guide groove is arranged on the side surface of the beam tube diameter passing wheel.
The utility model has the beneficial effects that: according to the utility model, tension can be controlled by changing the distance between the gravity center and the supporting shaft only by controlling the pressure of the air cylinder through a lever principle, and the tension control device has the advantages of simple structure, easiness in manufacturing, low cost, wear resistance, convenience in installation, high matching adaptability, suitability for optical cable production equipment of various manufacturers, and capability of effectively solving the problem of complex tension adjustment in optical cable production.

Detailed Description
All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
As shown in fig. 1-2, the variable tension pay-off control device for optical cable of the present invention comprises a beam tube diameter wheel 1 and a cylinder 3;
an inserting frame 5 is connected to an output shaft of the cylinder 3, and the beam tube diameter wheel 1 is limited at the front end of the inserting frame 5 through a limiting shaft 6.
In the embodiment, a balancing weight 4 is fixed on the cylinder 3, so that the balancing weight cannot move independently, and a support shaft 2 is installed on one side of the connecting end of the inserting frame 5 and is fixed on the cable former through the support shaft; the distance between the balancing weight and the supporting shaft is controlled by adjusting the pressure of the air cylinder, so that the tension is adjusted.
In this embodiment, the side of the beam tube diameter wheel 1 is provided with a beam tube guide groove 7.
The working principle is as follows:
during the production of the cable, the beam tube passes through the path after being installed on the pay-off rack and passes through the beam tube diameter passing wheel of the tension control device, the supporting shaft is fixed on the cable former, during the production of equipment, the tension of the pay-off of the beam tube is adjusted according to different beam tubes, the telescopic position of the air cylinder can be controlled by quickly changing the pressure of the air cylinder, so that the position of the balancing weight fixed on the air cylinder is driven to move, and the distance between the gravity center position and the supporting shaft is changed through a simple lever principle to control the tension.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
