The roll diameter detector is an infrared detector. The brake is a magnetic powder brake connected with the unwinding roller. The utility model discloses can roll up the change in footpath and brake according to the filter screen to guarantee the filter screen product with the tension transmission of invariant, thereby make ultimate filter screen product property even, product quality can promote.
Description
Technical Field
The utility model relates to a filter screen production facility field, concretely relates to permanent tension unreels and cuts device.
Background
And in the final stage of the production flow of the filter screen, the unreeling and cutting device is adopted to transmit and cut and mold the filter screen product. The conventional unreeling and cutting device only comprises a plurality of rollers and a cutter, and a filter screen product is conveyed by the rollers in sequence to form a roll shape and is finally cut by the cutter. In the transmission process of filter screen product, because the filter screen book that the rolling formed footpath constantly changes, and the device other part parameter is unchangeable, the tension that leads to the filter screen product when transmitting between each roller changes along with the change of book footpath, and then leads to the filter screen product after the section to have inhomogeneous problem, influences product quality.
Disclosure of Invention
The utility model aims at providing a can keep permanent tension transmission filter screen product to make the permanent tension that the product homogeneity can improve unreel and cut the device.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
the utility model provides a device is cut in constant tension unreeling for unreel and cut the filter screen product, constant tension unreels and cuts the device and is in including unreeling roller, wind-up roll and a plurality of setting unreeling roller with guide roll between the wind-up roll, constant tension unreels and cuts the device and still including being used for detecting on the wind-up roll the filter screen that the filter screen product formed is rolled up the book footpath detector, with it is connected and based on to roll up the footpath detector the controller that the volume footpath output of filter screen book corresponds control signal, with the controller be connected and based on control signal to unreel the roller release and correspond the brake force and adjust filter screen product tension's stopper.
Preferably, the roll diameter detector is an infrared detector.
Preferably, the brake is a magnetic powder brake connected with the unwinding roller.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages: the utility model discloses can roll up the change in footpath and brake according to the filter screen to guarantee the filter screen product with the tension transmission of invariant, thereby make ultimate filter screen product property even, product quality can promote.
Drawings
Fig. 1 is the utility model discloses a constant tension unreels and cuts device's schematic diagram.
In the above drawings: 1. unwinding rollers; 2. a wind-up roll; 3. a guide roller; 4. a roll diameter detector; 5. and a brake.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The first embodiment is as follows: as shown in the attached drawing 1, the constant-tension unreeling and slitting device comprises an unreeling roller 1, a reeling roller 2, a plurality of guide rollers 3 and a slitter. Wherein, unreel roller 1, wind-up roll 2 and each 3 axial parallel arrangement of guide roll, guide roll 3 is crisscross to be set up between unreeling roller 1 and wind-up roll 2, unreels roller 1, wind-up roll 2 and is driven by the motor that corresponds respectively and rotates. The slitter is arranged near the wind-up roll 2. The filter screen product is output by the unwinding roller 1, sequentially passes through the guide rollers 3, and is wound on the winding roller 2 to form a filter screen roll.
The constant-tension unreeling and slitting device further comprises a reeling diameter detector 4, a controller and a brake 5.
The roll diameter detector 4 is used for detecting the roll diameter of a filter screen roll formed by the filter screen product on the winding roller 2, so as to output a corresponding detection signal. In this embodiment, the roll diameter detector 4 is an infrared detector disposed above the wind-up roll 2.
The controller is in signal connection with the roll diameter detector 4 so as to receive the detection signal output by the roll diameter detector 4 and output a corresponding control signal based on the roll diameter of the filter screen roll. The controller may be integrated in a control system of the constant-tension unwinding slitting device, which is not shown in the figure.
The brake 5 is in signal connection with the controller so as to receive the control signal output by the controller, and the brake 5 is connected with the unwinding roller 1 so as to release the corresponding braking force to the unwinding roller 1 based on the control signal to adjust the tension of the filter screen product. In this embodiment, the brake 5 is a magnetic powder brake.
In the above-mentioned scheme, different book footpath corresponds there is different brake force to make the filter screen product between unreeling roller 1 and the take-up roll 2 keep invariable tension through the braking to unreeling roller 1, and then ensure product quality.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
