Fiberglass Tape Thermoplastic composite pipe (TCP/RTP) Wrapping Machine Patent 02 - Feeding Structure

Fiberglass tape-reinforced thermoplastic composite pipe (TCP/RTP) wrapping Machine structure utility model pertains to the technical field of winding machines, particularly relating to an active control tape feeding structure for a winding machine.


Background of TCP co-axis wrapping machine tape feeding Technology


The existing fiberglass tape tape-winding machines traditionally utilize a passive tape wrapping structure. A significant disadvantage of this is the uneven tension during the winding process, which affects the tape winding effect.


The current method of driving the tape in winding machines involves the powered rotation of a winding pad, which guides the glass fiber tape from the fiberglass tape pad onto an inner polyethylene tube for wrapping. As the fiberglass tape pad rotates without power, acting as a follower component, a certain force is needed to drive the rotation of the fiberglass tape pad. This results in tension in the glass fiber tape during the wrapping, and if the tension is too high, it can cause the inner core tube's reinforcing layer to shake during winding. Severe shaking may lead to production line failure and operational shutdown.

The above winding machine active control tape feeding structure further includes: a frame and a reducer, with the reducer installed on the frame and located below the main shaft, the reducer having a main shaft chain installed on it, and the main shaft fitted with a main shaft sprocket, with the main shaft chain and the main shaft sprocket in transmission connection.


The above winding machine active control tape feeding structure further includes:


1、A transmission shaft assembly, which is installed on the winding pad, with one end of the tape feeding reducer and the dual-shaft magnetic powder clutch in transmission connection, and the other end of the dual-shaft magnetic powder clutch in transmission connection with the transmission shaft assembly.


2、A bearing housing, which is installed on the frame, and the main shaft is mounted on the bearing housing.


3、The above winding machine active control tape feeding structure, wherein, the transmission shaft assembly is in transmission connection with the fiberglass tape tape pad.


4、At least one of the guide rods is set in the radial direction of the fiberglass tape pad.


The above winding machine active control tape feeding structure, wherein, each guide rod includes a fixed part and a rod-shaped part, with the fixed part being fixed in place and one end of the rod-shaped part rotatably connected to the fixed part.


Due to the adoption of the above technology, the utility model has the following positive effects compared with the existing technology:


(1)   Since the winding part of this utility model is a rotating component, it uses conductive slip rings for power supply. Once the reducer is powered, it outputs power to the dual-shaft magnetic powder brake. The magnetic powder brake has a concentric and different shaft structure. The reducer outputs torque in a constant mode, which cannot control the output torque size, but after output through the magnetic powder clutch, the magnetic powder clutch can effectively control the output torque within a certain range. This allows the use of an electrical control system to control the power structure, thus achieving stable winding tension and adjustable torque.



(2)   This utility model solves the problem of excessive tension during winding that causes core tube shaking, making winding more stable and avoiding inconsistencies in winding gaps due to shaking, changing from a passive tape structure to an active tape delivery wrapping structure, representing a significant improvement in equipment.

(3)   This utility model changes the original transmission structure, linking one end of the magnetic powder clutch with the reducer and the other end with the fiberglass tape pad, thus achieving controllable tension.


(4)   This utility model adds conductive slip rings to supply power to the reducer magnetic powder brake.
