The utility model relates to a thickness compensation arrangement of film utilizes the slider to drive frequency conversion heater along slide rail lateral shifting to the local low temperature position that corresponds, and frequency conversion heater begins to heat, and under the heat preservation of guard shield, the water conservancy diversion effect, the local low temperature region on the main roll is heated and is heaied up, and when main roll surface temperature was unanimous, frequency conversion heater stopped heating, so can guarantee that the film product thickness of follow-up formation is even.
Description
Technical Field
The utility model relates to a thickness compensation arrangement of film. Belongs to the technical field of films.
Background
Whether the thickness of the film is uniform or not is an important index for detecting the quality of a film product, the non-uniformity of the film not only affects the tensile strength and the barrier property of each position of the film, but also causes the rolled surface of the film to have rib explosion, the film at the rib explosion position forms permanent deformation, and the subsequent processing of the film is affected, such as the unevenness of the film surface, the loose and drooping of the film, and further affects the subsequent compounding, printing, aluminizing, bag making and the like.
When the film is rolled, the thickness is directly related to the temperature on the roller, and when the temperature on the roller is not uniform, the thickness of the film is thicker in a local area with lower temperature, so that the thickness uniformity of the finished film is influenced.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned not enough, provide a thickness compensation arrangement of film.
The purpose of the utility model is realized like this:
a film thickness compensation device is characterized in that: the automatic feeding device comprises a rack, a main roller, a sliding rail, a sliding block, a variable frequency heater and a protective cover, wherein the main roller is arranged on the rack, the sliding rail is arranged at a distance from the main roller, two ends of the sliding rail are fixed on the rack, the sliding block is arranged on the sliding rail, the variable frequency heater is arranged on the sliding block, the variable frequency heater faces the main roller, and the protective cover is arranged on the outer side of the sliding rail.
Furthermore, the protective cover is arc-shaped, and the connecting line of the two arc-shaped end parts of the protective cover exceeds the position of the variable frequency heater.
Furthermore, the axis of the circle where the arc of the protective cover is positioned and the axis of the main roller are positioned on the same straight line.
Furthermore, the slide rail is a linear guide rail, the axis of the slide rail and the axis of the main roller are on the same plane, and the slide block moves transversely along the slide rail.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model relates to a thickness compensation arrangement of film, the film is when the calendering, the surface temperature of infrared ray thermoscope real-time supervision main roll, when the main roll has local temperature lower, the slider drives frequency conversion heater along slide rail lateral shifting to corresponding this local position, frequency conversion heater begins to heat, at the heat preservation of guard shield, under the water conservancy diversion effect, the local low temperature region on the main roll is heated and is heaied up, when infrared ray thermoscope detects main roll surface temperature unanimous, frequency conversion heater stop heating, so can guarantee that the film product thickness of follow-up formation is even.

In the figure:
the device comprises a frame 1, a main roller 2, a slide rail 3, a slide block 4, a variable frequency heater 5 and a shield 6.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Referring to fig. 1-2, the utility model relates to a film thickness compensation device, which comprises a frame 1, a main roller 2, a slide rail 3, a slide block 4, a variable frequency heater 5 and a protective cover 6, wherein the main roller 2 is arranged on the frame 1, the slide rail 3 is at a distance from the main roller 2, two ends of the slide rail 3 are fixed on the frame 1, the slide block 4 is arranged on the slide rail 3, the variable frequency heater 5 is arranged on the slide block 4, the variable frequency heater 5 faces the main roller 2, and the protective cover 6 is arranged outside the slide rail 3;
the shield 6 is arc-shaped, and the connecting line of the two arc-shaped ends of the shield 6 exceeds the position of the variable frequency heater 5 for the turbulence of hot air flow.
The axis of the circle of the arc of the shield 6 is on the same straight line with the axis of the main roller 2.
The slide rail 3 is a linear guide rail, the axis of the slide rail 3 and the axis of the main roller 2 are on the same plane, and the slide block 4 moves transversely along the slide rail 3.
An ANJ-10 type variable frequency digital electromagnetic heater produced by Xiamen Ji science and technology Limited.
The working principle is as follows:
when the film is rolled, the infrared thermometer monitors the surface temperature of the main roller 2 in real time, when the local temperature of the main roller 2 is lower, the slide block 4 drives the variable frequency heater 5 to transversely move to a position corresponding to the local position along the slide rail 3, the variable frequency heater 5 starts to heat, the local low-temperature area on the main roller 2 is heated and heated under the heat preservation and flow guide effects of the shield 6, and when the infrared thermometer detects that the surface temperature of the main roller 2 is consistent, the variable frequency heater 5 stops heating, so that the thickness of a subsequently formed film product is ensured to be uniform.
In the above embodiments, the present invention has been described only by way of example, but various modifications may be made by those skilled in the art after reading the present patent application without departing from the spirit and scope of the invention.
