Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of measuring tools, in particular to a tool for measuring the gap between a die head and a film lip. Background Art
[0002] In the BOPP (biaxially oriented polypropylene) capacitor film production line, the die lip gap, as one of the key equipment parameters, has a vital impact on the thickness uniformity of the product and the stability of the production line. The die lip gap refers to the spatial distance between the die lip and the cavity in the mold. The precise control of this parameter is directly related to the quality and production efficiency of the capacitor film. At present, a tool commonly used by capacitor film manufacturers to measure the die lip gap is a simple measuring device composed of copper sheets of different thicknesses. Although this method is simple to operate, it has great limitations and errors. First, there may be slight differences in the thickness of the copper sheet, resulting in inaccurate measurement results; secondly, manual operation is easily affected by human factors, such as the force and angle when inserting the copper sheet, which may affect the accuracy of the measurement results; finally, this method cannot monitor the changes in the die lip gap in real time and continuously, and it is difficult to meet the requirements of the production line for stability and accuracy.

The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0027] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0028] Because the gap between the membrane lips is small and requires high precision, the material used for measurement needs to consider its material and temperature resistance. Currently, copper feeler gauges of different specifications and thicknesses are used. Each measurement requires multiple measurements with feeler gauges of different thicknesses. Inserting feeler gauges of different thicknesses into the membrane lips to accurately measure the gap between the membrane lips is not only inconvenient and time-consuming, but also extremely inefficient. Moreover, the hardness of thick sheets with a thickness of less than 0.3mm is relatively low, and the deformation resistance is relatively poor. They are easily deformed and worn during use, and their service life is relatively short. Therefore, refer to Figures 1 to 3 The utility model is a tool for measuring the gap between the die head and the film lip, and the following embodiments are made:
[0029] In some embodiments, a tool for measuring the gap of the die film lip is used to measure the gap of the die film lip, especially to measure the gap of the die film lip of a BOPP capacitor film production line, including a handheld outer frame 100 for conveniently holding the entire measurement work during measurement, and a bottom film 200 and a plurality of superimposed sheets 300 are rotatably provided at one end of the handheld outer frame 100, the thickness of the bottom film 200 is greater than the upper surface of the superimposed sheets 300, and the thickness of the superimposed sheets 300 is the same, which is 0.05 mm. Multiple superimposed sheets 300 are sequentially superimposed on the bottom film 200, and the thickness of the bottom film 200 is 0.6 mm.
[0030] This time, an integrated feeler gauge is used with gradually increasing thickness, that is, the first level thickness is 0.6mm, to ensure the strength of the feeler gauge and prevent it from bending easily; the thickness is increased by 0.05mm each time, and the interval of each level of thickness increase is 1mm. The design is matched according to the commonly used gap of the membrane lip, and the measuring range is 0.6mm~1mm.
[0031] Calculation formula:
[0032] L=0.6mm+n×0.05mm
[0033] Note: Each level of 0.05mm thickness is marked with numbers 1, 2, 3, etc. When the feeler gauge number is 3, it means the corresponding membrane lip thickness is 0.6mm+3×0.05mm, i.e. 0.75mm. There is no need to change different thicknesses for measurement, which is highly efficient.
[0034] When in use, the bottom film 200 is first inserted into the gap between the lip membranes, and then the number of the superimposed films 300 is gradually increased, and finally the measured lip membrane thickness is calculated according to the number of the superimposed films 300.
[0035] The design is matched with the common gap of the membrane lip, and the measuring range is 0.6mm~1mm. There is no need to frequently change the thickness of the feeler gauge for measurement. It is one-piece formed and the membrane lip gap measurement can be completed in one time, which effectively improves both convenience and efficiency; 0.6mm is the bottom film 200, which effectively guarantees the strength of the feeler gauge. Compared with a single-layer 0.05mm feeler gauge, the 0.05mm increase layer by layer will not bend and deform due to being too thin, and can be reused many times.
[0036] As a further improvement, the handheld outer frame 100 is provided with a mounting groove, and the bottom film 200 and the superimposed film 300 are rotatably arranged in the mounting groove. It is convenient to hold during measurement, and it plays a role in protecting the bottom film 200 and the multiple superimposed films 300. And grooves 110 are correspondingly provided on the two side walls of the mounting groove, which is convenient for pulling out the superimposed films 300. When measuring, the bottom film 200 and the superimposed films 300 are pulled out in sequence from the lower grooves 110.
[0037] In some other embodiments, the bottom film 200 and the superimposed film 300 can be extended from the other end of the handheld outer frame 100, and the bottom film 200 and the superimposed film 300 can be directly moved from the end, which can also facilitate the movement of the superimposed film 300, but the handheld outer frame 100 cannot play a better protective role.
[0038] As a further improvement, the bottom sheet 200 and the superimposed sheet 300 are both metal components, which are not easy to rust and can be made into thinner sheets, such as copper sheets, stainless steel sheets, etc.
[0039] As a further improvement, the bottom film 200 and the superimposed film 300 are both in the shape of long strips, so as to be easily inserted into the gap between the labial membranes, and the bottom film 200 and the superimposed film 300 have uniform thickness, so as to improve the measurement accuracy.
[0040] As a further improvement of the above technical solution, the plurality of superimposed sheets 300 are engraved with gradually increasing numbers in sequence, for example, the superimposed sheet 300 close to the bottom film 200 has a last digit 1, and the other superimposed sheets 300 are engraved with numbers such as 2, 3, and 4 in sequence, and the numbers are close to the superimposed sheets 300 and rotated on one end of the handheld outer frame 100, which does not extend into the lip film gap and will not be blocked, so that the number of superimposed sheets 300 can be directly read. The number on the superimposed sheet 300 is used to determine how many superimposed sheets 300 are used, without adding the number of superimposed sheets 300 used. For example, if the number of the top superimposed sheets 300 is 3, the thickness of the lip film is 0.6+3*0.05=0.75 mm; if the number of the top superimposed sheets 300 is 4, the thickness of the lip film is 0.6+4*0.05=0.80 mm.
[0041] Further improvement, the bottom film 200 and the superimposed film 300 are both thickness values, the bottom film 200 is engraved with a thickness of 0.6 mm, and the superimposed film 300 is engraved with a thickness of 0.05 mm. The handheld outer frame 100 is engraved with a measured total thickness, and the measuring range of the measuring tool can be directly known.
[0042] The preferred implementation modes of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
