Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline production equipment, in particular to a steel wire pay-off compensation mechanism for steel wire rubber pipe production. BACKGROUND

[0002] Steel wire rubber pipe refers to a kind of pipe combined by spiral steel wire and rubber, which has good flexibility, anti-collapse and bending advantages. In the production process, the cooperation of the steel wire pay-off mechanism is needed to release the steel wire from the steel wire reel, so as to complete the steel wire release and realize the spiral winding of the steel wire supply.

[0003] The existing patent with Chinese patent publication number CN212334203U, the name of which is "a steel wire pay-off device for steel wire reinforced hose production", the patent includes "a body, the outside of the body is provided with a protective shell, the right side of the protective shell is fixedly installed with a driving motor, the output shaft of the driving motor is fixedly installed with a winding reel, and the bottom of the winding reel is provided with a connecting block. The steel wire pay-off device for steel wire reinforced hose production drives the outer sleeve to rotate through the servo motor, so that the inner sleeve rod pushes the connecting rod to move upward, which facilitates lifting the winding reel upward, without manual lifting of the winding reel, and one person can complete the installation of the winding reel, saving manpower, and the left side of the bottom plate is designed into a bevel shape, which facilitates pushing the winding reel to the bottom plate, further reducing the difficulty of manual handling, and making the device more labor-saving and convenient to use".

[0004] However, although the existing technology can realize normal pay-off of the steel wire, it is known that the existing steel wire is wound on the steel wire reel, and the steel wire reel needs to rotate to release the steel wire in the use process. The actual rotation of the steel wire reel is usually uniform speed by driving equipment, and the existing problem of this mode is that the winding diameter of the steel wire on the steel wire reel becomes smaller and smaller due to the release of the steel wire, so the steel wire reel needs to gradually increase the rotating speed. If the steel wire reel is directly driven by the driving equipment with gradually increasing speed, it is difficult to ensure that the speed increased by the driving equipment can exactly meet the speed of the actual release of the steel wire, the rotating speed of the steel wire reel is too fast, which causes the accumulation of the steel wire, and the speed of the steel wire supply is too slow. In order to solve the above problems, we propose a steel wire pay-off compensation mechanism for steel wire rubber pipe production. SUMMARY
