Description
Technical Field
The utility model relates to a yardstick measurement technical field especially relates to an interval measuring device between roller.
Background
In the composite manufacturing process of PET film, a plurality of sets of film rolls are often used to perform precision processing on the film. In actual manufacturing, because the width of the PET film is high (1-2 m) and the thickness is low (common dimensions are 0.036mm,0.05mm and 0.125mm), once an unstable factor is generated in a working condition, the film is easy to generate wrinkles tangential to the film transmission direction, so that PET convolution is built up, the production line is suspended and adjusted slightly, and the product yield is seriously reduced.
The inventor researches that the most significant influence effect of the unstable factors is the phenomenon that the distance difference between film rollers causes uneven radial stretching, thereby causing the wrinkles of the film. However, to measure the distance between the cylindrical film rollers, it is very difficult to ensure the angle conditions between the measurement points of multiple measurements to be consistent by using the conventional measurement tool with a scale type, and it is difficult to maintain the distance between the rollers to be consistent with a high precision.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problems in the prior art, the utility model provides a measuring device for the distance between rollers, which comprises a measuring part and a fixing part, wherein the measuring part is fixedly connected with the fixing part, and the fixing part is used for fixing the measuring device on the rollers; the measuring part comprises a measuring rod consisting of a plurality of connecting rods which are detachably connected with each other and a measuring mechanism connected to the top of the measuring rod; the bottom of the measuring rod is fixedly connected with the fixing part; the measuring mechanism comprises a pressure gauge and a pressure thimble, and the needle point of the pressure thimble points to the direction from the bottom to the top of the measuring rod.
Preferably, the fixing part comprises a square plate and a fixing hoop fixedly connected to the square plate and used for fixing the measuring rod.
The diameter direction of the fixed hoop is perpendicular to the direction of the roller shaft of the roller to be measured, so that the contact angle between the measuring rod and the roller to be measured is guaranteed, and the measurement is accurate and convenient.
The connecting rod is including being equipped with the first end of internal thread and being equipped with the second end of external screw thread, this internal thread and external screw thread adaptation constitute the measuring stick through the combination of above-mentioned a plurality of connecting rods for length-adjustable is applicable to more measuring situation.
The measuring rod top end still wears to be equipped with a connecting plate, the pressure thimble wears to locate on this connecting plate.
The fixing portion, the measuring rod and the pressure thimble are made of rigid materials.
Has the advantages that: (1) the measurement accuracy is high: the measurement mechanism is formed by the cooperation of the pressure gauge and the pressure thimble, and is different from the measurement of the common specification and scale in the field, so that the measurement precision is higher; (2) the application range is wide: the detachable connecting rod is utilized to form the measuring rod body, and the length of the measuring rod can be easily adjusted, so that the measuring rod is suitable for more application environments, and the application range is enlarged; (3) the use is convenient: the right-angle-shaped fixing part can simply and effectively provide a supporting effect for the measuring device, and meanwhile, the measuring device can measure in real time without more complex operations, and is convenient to use.
