Embodiment Construction

[0020] The technical solution adopted by the present invention will be further described below in combination with schematic diagrams.

[0021] Such as figure 2 , a new type of constant tension device for longitudinal wrapping of aluminum-plastic composite tape, which includes a tape release frame 100, a pneumatic brake 101, a straightening roller assembly 104, and a tension sensor 105.

[0022] see image 3 , the tape rack 100 installs the aluminum-plastic composite tape roll through the release shaft 200 of the aluminum-plastic composite tape roll, image 3 Aluminum-plastic composite tape volume release shaft 200 is not installed with aluminum-plastic composite tape volume. The end of the tape roll protrudes from the bearing seat so as to install the corresponding brake assembly. A pneumatic brake 101 is installed at the release shaft of the aluminum-plastic composite tape of the tape rack, and the pneumatic brake 101 can brake the release shaft of the aluminum-plastic co...

Abstract

The invention provides a novel aluminum-plastic composite belt longitudinal wrapping and releasing tension constant device, which comprises a belt releasing frame, a pneumatic brake installed at an aluminum-plastic composite belt releasing shaft of the belt releasing frame, and a straightening roller assembly arranged on a straightening roller mounting frame and provided with a tension sensor. Thepneumatic brake and the tension sensor are connected to a controller. The brake and the belt releasing frame of the releasing tension constant device are integrated as a whole. After the belt is released by the belt releasing frame, the belt is straightened by the straightening roller. Meanwhile, the tension borne by the belt is fed back to a PLC integrated control system through the tension sensor. The PLC integrated control system compares the tension fed back by the tension sensor with a preset tension and then sends an adjusting signal to a pneumatic proportional control valve. The pneumatic proportional control valve uses compressed air as a power source and uses an air cylinder as an actuator to achieve proportional adjustment of a brake for braking or loosening. Therefore, the constant tension is achieved.

Description

technical field [0001] The invention relates to the field of cable processing equipment, in particular to a novel device for constant tension of aluminum-plastic composite tapes in longitudinal wrapping. Background technique [0002] The comprehensive sheath composed of aluminum-plastic composite tape longitudinal wrapping and PE extrusion is widely used in occasions with high waterproof requirements. Generally, the thickness of the longitudinally wrapped aluminum-plastic composite tape for waterproofing is 0.25mm, and the thickness of the base tape is not less than 0.2mm. Due to the thicker tape and the different ductility of metals and plastics, the unwinding tension changes as the tape decreases. see figure 1 , the figure is a schematic diagram of the aluminum-plastic composite tape longitudinal wrapping production line, which includes a tape unwinding device 1, a preforming die 2, a sizing die 3, an extruder head 4, a guide roller 5, a gluing device 6, and a gluing dev...
