Novel aluminum-plastic composite belt longitudinal wrapping and releasing tension constant device

[0020] The technical scheme adopted by the present invention will be further described below in conjunction with the schematic diagram.

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

[0022] See image 3 , The tape release rack 100 installs the aluminum-plastic composite tape roll through the aluminum-plastic composite tape roll release shaft 200, image 3 The aluminum-plastic composite tape roll release shaft 200 is not equipped with aluminum-plastic composite tape rolls, and the aluminum-plastic composite tape roll release shaft 200 is installed on the tape rack through the bearing seat, and the aluminum-plastic composite tape roll release shaft 200 is not installed with aluminum-plastic composite tape. The tape winding end extends out of the bearing seat to install the corresponding brake components. A pneumatic brake 101 is installed at the aluminum-plastic composite tape release shaft of the tape rack. The pneumatic brake 101 can brake the aluminum-plastic composite tape release shaft Furthermore, the effect of tensioning the aluminum-plastic composite belt is realized, and the tightness of the aluminum-plastic composite belt in the whole system is adjusted by the tightness of the pneumatic brake. A straightening roller assembly 104 is provided in the output direction of the aluminum-plastic composite belt coil of the belt release frame 100. , The straightening roller assembly 104 includes a first straightening roller 104a and a second straightening roller 104b arranged on the top of the straightening roller mounting frame 300 and arranged side by side. The aluminum-plastic composite belt is guided by the first straightening roller The straightening roller assembly 10 is finally led out of the straightening roller assembly 10 from the second straightening roller. A third straightening roller 104c is arranged under the first straightening roller. The lower part is provided with a fourth straightening roller 104d. The height of the second straightening roller is greater than the installation height of the first straightening roller. In order to facilitate the description of the winding form of the aluminum-plastic composite belt in the straightening roller assembly, The side of the straightening roller component facing the release shaft of the aluminum-plastic composite belt is defined as the front side of the straightening roller component. Correspondingly, the side of the straightening roller component away from the release shaft of the aluminum-plastic composite belt is defined as the straightening roller. On the rear side of the component, the winding form of the aluminum-plastic composite tape will be described below (see Figure 4 ): The aluminum-plastic composite belt 400 is introduced into the straightening roller assembly from the upper surface of the first straightening roller, and then downward from the rear side of the first straightening roller, enters the front side of the third straightening roller, and then passes through the first straightening roller. The lower surface of the three straightening roller enters the lower part of the fourth straightening roller, and then enters the back side of the second straightening roller through the rear side of the fourth straightening roller, and finally the surface of the second straightening roller faces the aluminum-plastic The composite tape roll release shaft 200 outputs the aluminum-plastic composite tape horizontally.

[0023] A tension sensor 105 is installed at the straightening roller assembly 104, and the tension sensor 105 can be installed at the second straightening roller.

[0024] To facilitate control, the pneumatic brake and tension sensor are connected to the controller, the pneumatic proportional control valve 102 connected to the pneumatic brake is connected to the controller 103, and the tension sensor 105 is also connected to the controller. The controller includes but is not limited to PLC Controller.

[0025] The brake of the tape-releasing tension constant device is an integral device with the tape-releasing frame. After the unwinding rack is placed, the belt is straightened by the straightening roller, and the tension of the belt is fed back to the PLC integrated control system through the tension sensor. The PLC integrated control system compares the tension with the set tension according to the tension feedback from the tension sensor Give a regulating signal to the pneumatic proportional control valve. The pneumatic proportional control valve uses compressed air as the power source and the cylinder as the actuator to realize the proportional adjustment brake to brake or relax, so as to achieve a constant tension.

[0026] The description of the known technology is omitted in the full text. For example, the installation method of the tension sensor 105 can refer to the existing technology, and will not be described in detail here.

[0027] The above are only preferred embodiments of the present invention, and do not play any limiting effect on the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, makes any form of equivalent replacement or modification and other changes to the technical solution and technical content disclosed by the present invention, which does not depart from the technical solution of the present invention. The content still falls within the protection scope of the present invention.
