Description

Technical Field

[0002] Papermaking is one of the four great inventions of China. As the main writing medium, paper plays an important role in the development of human civilization. The documents, calligraphy, paintings, manuscripts and other cultural relics preserved to this day have precious artistic and scientific value. They are one of the important research objects of archaeologists, and the thickness detection of paper is also an important research step. Since the wrinkles of the objects to be detected will cause partial overlap of the objects to be detected, resulting in inaccurate thickness detection results, the existing thickness detection equipment will be equipped with at least two tensioning rollers, and the tensioning rollers will be used to tighten the two ends of the objects to be detected to keep the surface of the objects to be detected flat. However, the paper that has been preserved to this day has been severely aged due to the influence of light and air for a long time, and the paper tension is insufficient and the strength is reduced. The use of tensioning rollers will cause the surface of the paper to be overstressed and break. Therefore, the existing thickness detection equipment cannot meet the needs of archaeology.

The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0023] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0024] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0025] refer to Figures 1 to 5 The paper thickness detection device according to a preferred embodiment of the present invention will be described in detail below. The paper thickness detection device includes a device body 10, a supporting mechanism 20, a detection mechanism 30 and a control mechanism 40.

[0026] Specifically, the device body 10 includes a supporting component 11 and an installation component 12, and the supporting mechanism 20 is installed on the supporting component 11. The supporting mechanism 20 has a plurality of paper fixing parts 21 and a receiving wall 22, and the paper is laid on the receiving wall 22. The supporting mechanism 20 is penetrated from top to bottom to form at least one through groove 201, wherein the portion of the paper laid on the receiving wall 22 corresponding to the through groove 201 is the detection area of ​​the paper. A through groove 201 is formed between two adjacent paper fixing parts 21. Each of the paper fixing parts 21 forms a plurality of adsorption channels 2101 spaced apart in the horizontal direction. The end of the adsorption channel 2101 away from the receiving wall 22 is connected to the negative pressure device through a pipeline, so that the supporting mechanism 20 forms a negative pressure on one side of the receiving wall 22 to fix the paper laid on the receiving wall 22. Because the paper of ancient books has aged seriously under the influence of light and air, it has problems such as insufficient tension and reduced strength. Negative pressure adsorption can fix the paper while preventing the paper surface from being broken due to excessive force, so as to complete the detection of paper thickness without damaging the paper.

[0027] The detection mechanism 30 includes a detection component 31 and a transmitting component 32, and the detection component 31 and the transmitting component 32 are both installed on the installation component 12. The detection component 31 and the transmitting component 32 are arranged with a relative interval up and down. The supporting mechanism 20 and the paper carried by it can pass between the detection component 31 and the transmitting component 32. The transmitting component 32 is used to radiate detection rays toward the detection component 31, and the detection component 31 is used to receive the detection signal generated by the transmitting component 32 after radiating and passing through the detection area. The detection component 31 is communicatively connected with the control mechanism 40, and the detection component 31 is configured to send the detection signal received by itself to the control mechanism 40, and the control mechanism 40 is configured to calculate the thickness of the paper according to the detection signal transmitted by the detection component 31.

[0028] That is to say, when the inspector lays the paper flat on the receiving wall 22, the paper fixing part 21 fixes the paper on the surface of the supporting mechanism 20 through the negative pressure in the adsorption channel 2101, and then the supporting mechanism 20 and the paper it carries penetrate between the detection component 31 and the emitting component 32, wherein the emitting component 32 radiates rays to the detection component 31, and the rays are received by the detection component 31 after passing through the detection area of ​​the paper, and the control mechanism 40 measures the thickness of the paper according to the detection signal received by the detection component 31. Since the paper is fixed by negative pressure after being laid flat on the supporting mechanism 20, during the detection process, the paper is always laid flat on the receiving wall 22, thereby avoiding wrinkling of the paper and ensuring the accuracy of the thickness detection result of the equipment.

[0029] In one example, the detection mechanism 30 is implemented as an X-ray thickness gauge. The control mechanism 40 is implemented as a controller.

[0030] Those skilled in the art will appreciate that the paper thickness detection device can be used not only to measure the thickness of paper, but also to measure the thickness of materials such as textile fabrics, and no further description will be given here.

[0031] In one embodiment, the supporting mechanism 20 is provided with a pipe on a side wall facing away from the receiving wall 22, and the pipe is respectively connected to the adsorption channel 2101 and the negative pressure device, so that the airflow on the surface of the receiving wall 22 flows from the adsorption channel 2101 through the pipe to the negative pressure device, thereby adsorbing and fixing the paper laid flat on the surface of the receiving wall 22.

[0032] As a deformable form, the supporting mechanism 20 forms a flow channel 202 connected to the adsorption channel 2101. The flow channel 202 is connected to the negative pressure device through a pipeline, so that the airflow on the surface of the receiving wall 22 flows from the adsorption channel 2101 to the negative pressure device through the flow channel 202, thereby adsorbing and fixing the paper laid flat on the surface of the receiving wall 22. It is worth mentioning that compared with the previous embodiment, this embodiment reduces the use of pipelines, thereby avoiding the interference of pipelines on the detection area, thereby improving the detection accuracy of the paper thickness detection device.

[0033] Preferably, the adsorption channel 2101 includes a first section 21011 and a second section 21012 connected to the first section 21011. The first section 21011 is formed by gradually expanding one end of the second section 21012 in a radial direction, so that the first section 21011 is trumpet-shaped. The trumpet-shaped first section 21011 can increase the adsorption area of ​​the paper to enhance the fixing effect on the paper.

[0034] Preferably, the supporting mechanism 20 forms a plurality of through slots 201, and the through slots 201 have a preset length, and the plurality of through slots 201 are equidistantly distributed in a horizontal direction perpendicular to the length direction of the through slots 201. In order to facilitate those skilled in the art to understand the subsequent description, the length direction of the through slots 201 is now defined as the X-axis direction, and the horizontal direction perpendicular to the X-axis direction is defined as the Y-axis direction.

[0035] In one embodiment, the supporting mechanism 20 is slidably mounted on the supporting member 11, and the supporting mechanism 20 is configured to be movable along the Y-axis direction. That is, after the detection mechanism 30 finishes detecting one detection area of ​​the paper, the supporting mechanism 20 moves along the Y-axis direction so that the detection mechanism 30 detects the next detection area.

[0036] As a variation of the above embodiment, the mounting component 12 is slidably mounted on the supporting component 11 (not shown in the drawings). The mounting component 12 is configured to be movable along the Y-axis direction, thereby driving the detection mechanism 30 mounted on the mounting component 12 to move along the Y-axis direction, that is, after the detection mechanism 30 detects one detection area of ​​the paper, the mounting component 12 drives the detection mechanism 30 to move along the Y-axis direction, so that the detection mechanism 30 detects the next detection area. In order to facilitate those skilled in the art to understand the technical solution of the present application, the subsequent description is based on the above embodiment.

[0037] Preferably, the support component 11 forms a sliding guide rail 111 , the sliding guide rail 111 extends along the Y-axis direction, and the supporting mechanism 20 is slidably mounted on the sliding guide rail 111 .

[0038] Furthermore, the paper thickness detection device further includes a distance measuring mechanism 50. The distance measuring mechanism 50 includes an indicator 51 and a ruler 52, wherein the ruler 52 extends along the Y-axis direction. The ruler 52 is arranged opposite to the indicator 51, and the indicator 51 points to the scale line on the surface of the ruler 52. Either the ruler 52 or the indicator 51 is installed on the supporting mechanism 20, and the other is installed on the supporting component 11. The detection personnel observes the scale line on the surface of the ruler 52 pointed by the indicator 51 to read, so as to judge the moving distance of the supporting mechanism 20 along the Y-axis direction.

[0039] It is worth mentioning that the paper thickness detection device also includes a driving mechanism. The driving mechanism includes a first driving component, and the supporting mechanism 20 is drivingly connected to the first driving component. The first driving component is used to drive the supporting mechanism 20 to move along the Y-axis direction. Preferably, the first driving component is controllably connected to the control mechanism 40, and the control mechanism 40 can control the start and stop of the first driving component. Furthermore, the control mechanism 40 controls the first driving component to operate intermittently, so that after the detection mechanism 30 finishes detecting one of the detection areas of the paper, the first driving component drives the supporting mechanism 20 and the paper it carries to move a preset distance along the Y-axis direction, so that the detection mechanism 30 can detect the next detection area.

[0040] In one example, the first driving component is implemented to include a motor.

[0041] Preferably, the detection component 31 and the emitting component 32 are installed on the mounting component 12 in a manner of synchronously moving along the X-axis direction, so that the detection mechanism 30 can perform comprehensive detection on each detection area of ​​the paper. Specifically, when a detection area of ​​the paper laid on the supporting mechanism 20 corresponds to the detection component 31 and the emitting component 32, the detection component 31 and the emitting component 32 move synchronously along the X-axis direction. After the detection mechanism 30 completes the detection of the detection area, the supporting mechanism 20 moves along the Y-axis direction so that the detection mechanism 30 can detect the next detection area. It can be understood that the paper has a width direction and a length direction. The paper thickness detection device can detect the thickness of the paper in all directions in the width direction and the length direction of the paper. While ensuring the comprehensiveness and accuracy of the detection, it can also provide thickness detection for longer and wider paper.

[0042] In one embodiment, the mounting component 12 forms a limiting guide rail, the limiting guide rail moves along the X-axis direction, and the detecting component 31 and the emitting component 32 are both connected to the limiting guide rail.

[0043] Preferably, the driving mechanism includes a second driving component, and the detection component 31 and the emission component 32 are both drivingly connected to the second driving component. The second driving component is used to drive the detection mechanism 30 to move along the X-axis direction. Preferably, the second driving component is controllably connected to the control mechanism 40, and the control mechanism 40 can control the start and stop of the second driving component.

[0044] In one example, the second driving component is implemented to include a motor.

[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
