Problems solved by technology
[0002] At present, during the unwinding process of the packaging film on the packaging machine, as the diameter of the packaging film changes, the tension of the packaging film also changes accordingly, and then in the packaging process, the packaging effect is affected. The sensor controls the driving motor, but it is not equipped with a tension clutch, which cannot control the tension smoothly, and the use effect is poor

Embodiment Construction
[0010] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0011] Such as figure 1 As shown, a packaging film tension control mechanism, including rotating the packaging film installed on the packaging film supporting frame 1 inflatable shaft 2, driving the stepping motor to rotate the packaging film installed inflatable shaft 2, is arranged on the The tension clutch between the drive motor and the packaging film installation inflatable shaft 2, the tension sensor arranged on the support frame of the packaging film, and the stepping motor and the tension sensor are respectively connected. Electrically connected tension control board.

The invention discloses a packaging film tension force control mechanism comprising a packaging film mount swelling shaft rotatably arranged on a packaging film support, a stepping motor driving the packaging film mount swelling shaft to rotate, a tension force clutch arranged between the drive motor and the packaging film mount swelling shaft, a tension force sensor arranged on the packaging film support, and a tension force control panel respectively electrically connected with the stepping motor and the tension force sensor; the tension force clutch is employed, a tension force value is preset, and the tension force sensor can measure the rolling diameter of the packaging film in a film drawing process and send the result to the tension force control panel; the packaging film tension force control mechanism can automatically adjust the tension force, so the rolling diameter of the packaging film can contentiously change in the whole unreeling process, thus realizing relative balance of the whole film tension force; the packaging film tension force control mechanism is stable in work.
Description
technical field [0001] The invention relates to a packaging film tension control mechanism. Background technique [0002] At present, during the unwinding process of the packaging film on the packaging machine, as the diameter of the packaging film changes, the tension of the packaging film also changes accordingly, and then in the packaging process, the packaging effect is affected. The sensor controls the driving motor, but it is not provided with a tension clutch, so it cannot control the tension smoothly, and the use effect is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the defects in the prior art and provide a packaging film tension control mechanism that can automatically adjust the tension during the unwinding process of the packaging film so that the tension of the packaging film reaches a balance. [0004] In order to achieve the above object, the technical solution of the present invention is to provide a packagi...
