Abstract
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
The present invention relates to a kind of packaging film tension control mechanism.
Background technology
Packaging film on current packer is in unreeling process, change along with packaging film coil diameter, the tension force of packaging film also changes therewith accordingly, then in packaging process, have impact on packaging effect, although being provided with tension pick-up in existing, drive motor is controlled, but is not provided with tension force clutch, can not to the steady control of tension force, result of use is poor.
Summary of the invention
It is an object of the invention to overcome the defect existed in prior art, it is provided that a kind of unreel in process at packaging film, it is possible to be automatically adjusted tension force so that packaging film tension force reaches the packaging film tension control mechanism of balance.
For achieving the above object, the technical scheme is that and provide a kind of packaging film tension control mechanism, gas expansion shaft is installed including rotating the packaging film being arranged on packaging film bracing frame, drive described packaging film to install motor that gas expansion shaft rotates, is arranged at described drive motor and described packaging film the tension force clutch between gas expansion shaft, the tension pick-up being arranged on described packaging film bracing frame, the tension control board that is electrically connected mutually with described motor and described tension pick-up respectively are installed.
As preferably, also include hold down gag, installing rack that described hold down gag includes being fixedly connected with described packaging film bracing frame, rotate depression bar that arranging rotates with described installing rack is connected with several live-rollers on described installing rack, one end, rotation is arranged at the pressure roller of the other end of described depression bar, described pressure roller pressure is located on the packaging film being installed on described packaging film installation gas expansion shaft.
As preferably, described tension force clutch is tension force magnetic powder cluth.
Advantages of the present invention and having the beneficial effects that: by using tension force clutch, by pre-set tension value, the process of work membrane is led to tension pick-up and to the measurement of the coil diameter of packaging film and feeds back to tension control board, it is automatically adjusted tension force, packaging film is made to unreel coil diameter in process be continually changing whole, but whole membrane tension force reaches relative equilibrium, working stability.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
In figure: 1, packaging film bracing frame；2, packaging film installs gas expansion shaft；3, installing rack；4, live-roller；5, depression bar；6, pressure roller.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described.Following example are only for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of packaging film tension control mechanism, installs gas expansion shaft 2 including rotating the packaging film being arranged on packaging film bracing frame 1, drive described packaging film to install motor that gas expansion shaft 2 rotates, is arranged at described drive motor and described packaging film and installs the tension force clutch between gas expansion shaft 2, the tension pick-up being arranged on described packaging film bracing frame, the tension control board that is electrically connected mutually with described motor and described tension pick-up respectively.
As shown in Figure 1, packaging film tension control mechanism also includes hold down gag, installing rack 3 that described hold down gag includes being fixedly connected with described packaging film bracing frame, rotate depression bar 5 that arranging rotates with described installing rack 3 is connected with several live-rollers 4 on described installing rack 3, one end, rotation is arranged at the pressure roller 6 of the other end of described depression bar 5, described pressure roller 6 is pressed and is located on the packaging film being installed on described packaging film installation gas expansion shaft 2.
As it is shown in figure 1, described tension force clutch is tension force magnetic powder cluth.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the technology of the present invention principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
