Calender capable of accurately measuring temperature

Technical Field

The invention belongs to the field of polytetrafluoroethylene film production, and particularly relates to a calender capable of accurately measuring temperature.

Background

A calender is a sheet processing machine that typically includes a set of calender rolls. The calendering roller group is composed of a plurality of calendering rollers arranged at intervals, and the number of the calendering rollers is different according to different processing requirements. The polytetrafluoroethylene film needs a lamp to look at flaws before rolling, a temperature sensor is usually adopted to measure the temperature of a rolling roller, if the temperature of the roller surface is too high, the rolling roller needs to be stopped for cooling, otherwise, the film is damaged. However, the temperature sensor is usually located close to the surface of the calender roll, and thus the temperature measurement is prone to be inaccurate, because the temperature of the outside air has an influence on the temperature of the test.

Furthermore, the illuminating lamp of the illuminating device extends to the front end of the rack through the adjusting hose, and the illuminating lamp and the temperature sensor are located on the same side of the rack, namely the feeding side.

Furthermore, a cooling roller is arranged at the feeding side of the frame.

Further, the upper end face of the cooling roller is flush with the upper end face of the driving roller.

Compared with the prior art, the calender capable of accurately measuring the temperature has the following advantages: the temperature sensor probe is embedded into the calendering roller in an embedded mode, so that the temperature measurement result is more accurate; and be equipped with the chill roll before the pan feeding calendering, cool down to the heat that the lamp produced, can reduce down time or can not shut down, improve production efficiency.

Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1-4, a calender capable of accurately measuring temperature comprises a frame 5, a driving roller 10, a driven roller 6, a temperature sensor 4 and a lighting device 1, wherein the driving roller 10 and the driven roller 6 are installed in the frame 5, the driving roller 10 is positioned below the driven roller 6, a circle of dovetail groove 7 is arranged at the edge of the driven roller 6, a probe 8 of the temperature sensor 4 is embedded into the dovetail groove, the probe 8 is not contacted with the driven roller 6, the frame 5 is connected with the temperature sensor 4 through a temperature sensor bracket 12, the upper end of the temperature sensor bracket 12 is fixed at the outer side of the frame 5 through a hinge 11, the lower end of the temperature sensor bracket 12 is fixed at the outer side of the frame 5 through a bolt 13, a spring 14 penetrates through the position between the temperature sensor bracket 12 and the frame 5 on the bolt 13, and two ends of the spring 14 respectively push against the temperature sensor bracket 12 and the frame 5, the lighting device 1 is mounted on the upper end of the frame 5.

The illuminating lamp 3 of the illuminating device 1 extends to the front end of the frame 5 through the adjusting hose 2, and the illuminating lamp 3 and the temperature sensor 4 are positioned on the same side of the frame 5, namely the feeding side.

A cooling roller 9 can be arranged at the feeding side of the frame 5, and the upper end surface of the cooling roller 9 is flush with the upper end surface of the driving roller 10.

When in use, the polytetrafluoroethylene film passes through the cooling roller 9 to cool the film, and then passes through the space between the driving roller 10 and the driven roller 6 to be rolled. The driven roller 6 is embedded with the probe 8 of the temperature sensor 4, and because the driven roller 6 needs to be finely adjusted in the vertical direction in actual use, the position of the probe 8 also needs to be adjusted along with the probe in the adjusting process, otherwise, the probe 8 is abraded in the rotating process of the driven roller 6. When the position of the probe 8 is adjusted, the position of the probe 8 is adjusted only by tightening or loosening the bolt 13 and adjusting the inclination angle of the temperature sensor 4, so that the probe 8 is always positioned in the dovetail groove 7. The dovetail groove 7 may be replaced by a groove having another shape, such as a rectangular groove, a semicircular groove, or the like.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
