Problems solved by technology
[0003] In the existing thickness detection devices for paper products, although a high-precision linear displacement sensor can be used to improve the detection accuracy, there are still the following problems: 1) Most of the existing devices detect the finished product and cannot be detected during the production process. On-line detection, that is, the information cannot be fed back in time, and problems are found; 2) The device is complicated and the cost is high; 2) When paper, film, etc. are mass-produced, they are generally laid flat on a smooth panel or wound on one or more rotating rollers Straightening and transshipment are carried out, and some parts that need to be detected are relatively narrow in space. The existing devices are generally complex in structure and cannot detect parts in narrow spaces.

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0034] The paper product thickness on-line detector of the present invention is used for the thickness on-line detection of paper product 24, and paper product 24 referred to here refers to all very thin sheet products as paper, and paper product 24 may be made of pulp Components may also be made from other materials such as paper made from pulp, mica paper, sheets and films.
[0035] Such as figure 1 As shown, an online thickness detector for paper products includes a bracket 7, a linear displacement sensor 4, a detection platform 1, a linear slider 2 and a display 12; the linear displacement sensor 4 is fixed on the bracket 7 and points downward, and the detection platform 1 The bottom of the bottom is provided with a roller 5 that can rotate around the shaft, the lowest end of the roller 5 is lower than the lowest end of the detection platform 1, th...

The invention relates to a paper product thickness online detector comprising a support, a linear displacement sensor, a detection table, a linear sliding bar, and a display. The linear displacement sensor is fixed to the support and points downwardly. The bottom of the detection table is equipped with a roller capable of rotating about an axis. The lowest end of the roller is lower than that of the detection table. The detection table is provided with a detection plane. The bottom of the linear displacement sensor is equipped with a rebound probe always in contact with the detection plane. The linear sliding bar is fixed to the detection table and is in parallel with the linear displacement sensor. The top of the linear sliding bar passes through the support and may slide along the direction of the linear sliding bar. The linear displacement sensor is connected with the display through the data line. When the paper product thickness online detector performs detection, the support is stationary, roller is in contact with a paper product, and the thickness direction of the paper product is the same as the direction of the linear displacement sensor. The paper product thickness online detector may detect the thickness uniformity of paper products in a production process, timely feeds back information, and is simple in structure, low in cost, and capable of detecting different parts.
Description
technical field [0001] The invention relates to a thickness detection device, in particular to an online thickness detection device for paper products. Background technique [0002] With the progress of modern industrial products, the precision requirements of various industries are gradually increasing, especially in the plate, paper, film and other industries, there are strict requirements for the uniformity of product thickness, and the thickness accuracy of some paper and film Requirements even reached 1μm. Therefore, a special thickness detection device is needed to detect the uniformity of the paper products in the thickness direction, so as to realize the quality monitoring and improvement of the paper products. [0003] In the existing thickness detection devices for paper products, although the high-precision linear displacement sensor is used to improve the detection accuracy, there are still the following problems: 1) Most of the existing devices detect the finis...
