The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order.

[0020] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it mutually exclusive, independent, or alternative to other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments.

[0021] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] like Figure 1 , 2As shown, a thickness gauge for using a variety of packaging materials includes a fixed base 1, which serves as the installation body of the thickness gauge. A handle 2 is provided on one side of the fixed base 1, and the handle 2 is integrally formed with the fixed base 1. The handle 2 is used to facilitate the user to hold the thickness gauge, thereby facilitating the transportation and movement of the thickness gauge. The fixed base 1 is provided with a placement table 3, a measuring instrument 4 and a downward pressing center column 5. The placement table 3 is used to place the product to be measured, and the measuring instrument 4 is used to obtain the thickness data of the measured product. In this embodiment, the measuring instrument 4 is also a dial indicator. In other embodiments, other instruments or devices that can obtain thickness data can also be used. The measuring end of the measuring instrument 4 is connected to the downward pressing center column 5, and the downward pressing center column 5 is limitedly installed on the fixed base 1 and can be lifted and slid on the fixed base 1. In the initial state, after the downward pressing center column 5 slides down to the limit position due to its own gravity, the reading of the measuring instrument 4 is zero; when measuring, after the product to be measured is placed on the placing table 3, the downward pressing center column 5 is pressed down by its own gravity to contact with the product to be measured, and the reading on the measuring instrument 4 is the thickness value of the current product to be measured.

[0023] Because each different packaging material has certain standards for measuring thickness, in order to improve the accuracy of measurement, a counterweight 6 is sleeved on the pressing center column 5, and a measuring head 7 is installed at the end of the pressing center column 5 away from the measuring instrument 4, and the counterweight 6 and the measuring head 7 are detachably connected to the pressing center column 5. The counterweight 6 is used to increase the weight of the pressing center column 5, thereby driving the measuring head 7 to move closer to the placement table 3. The downward force of the measuring head 7 can be changed by replacing different counterweights 6. In the actual measurement process, the downward force (pressure) required for each packaging material is different, and the pressure area is also different, so the thickness of the corresponding packaging material can be accurately measured by replacing the corresponding counterweight 6 and measuring head 7.

[0024] The following table lists some common packaging material thickness measurement standards:

[0025] Serial number Material Testing standards 1 Paper, cardboard GB / T-451.3 2 Corrugated cardboard, honeycomb cardboard GB / T-6547 3 Pressure sensitive tape GB / T-7125 4 Plastic film GB / T-6672 5 Foam plastics, rubber GB / T-6342 6 Wood-based panels GB / T-17657

[0026] During actual work, according to the measurement standard corresponding to the packaging material to be measured, different counterweights 6 and measuring heads 7 are replaced, and then the downward pressing center column 5 is lifted and the product to be measured is placed on the placement table 3. Then the downward pressing center column 5 is released. Under the action of the counterweights 6 and the gravity of the downward pressing center column 5, the downward pressing center column 5 will be pushed towards the placement table 3 until the measuring head 7 contacts the product to be measured. The thickness of the current product to be measured can be known by reading the data value on the measuring instrument 4.

[0027] It should be noted that by replacing different counterweights 6, the downward force of the central column 5 can be changed so that it meets the corresponding measurement standard; the lower end surface area of ​​each measuring head 7 is different, and by replacing different measuring heads 7, the measured pressure area can be changed to meet the corresponding detection standard. The thickness gauge can be used to measure the thickness of different packaging materials by counterweighting different counterweights 6 and different measuring heads 7, thereby improving versatility and user experience, without the need to purchase multiple thickness gauges, and reducing procurement costs.

[0028] like Figure 3 As shown, specifically, a mounting platform 8 is fixed on the downward pressing center column 5, and a clamping notch 61 is provided on the counterweight 6. The clamping notch 61 is clamped with the downward pressing center column 5, and the lower end surface of the counterweight 6 abuts against the mounting platform 8. The mounting platform 8 is used to limit the counterweight 6. The clamping notch 61 is provided on the counterweight 6 so that the counterweight 6 can be clamped with the downward pressing center column 5, and the counterweight 6 is fixed to the downward pressing center column 5 by the mounting platform 8; at the same time, the clamping method of the counterweight 6 and the downward pressing center column 5 also facilitates the replacement of the corresponding counterweight 6, thereby improving practicality.

[0029] In order to limit the downward movement of the pressing center column 5, a limit platform 9 is provided on the fixed base 1. When the thickness gauge is not in use, the pressing center column 5 will slide downward under the action of its own gravity until the mounting platform 8 abuts against the limit platform 9. The limit platform 9 limits the downward movement of the pressing center column 5 to prevent the pressing center column 5 from falling out of the fixed base 1, thereby improving the stability of the structure.

[0030] In this embodiment, in order to facilitate the installation of the measuring head 7, a connecting column 71 is provided at the upper end of the measuring head 7, and a connecting hole 51 is provided at one end of the pressing center column 5 away from the measuring instrument 4. The connecting column 71 is provided with an external thread, and the connecting hole 51 is provided with an internal thread. When installing the measuring head 7, the connecting column 71 is inserted into the connecting hole 51, and then the connecting column 71 is tightened to be threadedly connected and fixed with the connecting hole 51. In other embodiments, the measuring head 7 can also be connected to the pressing center column 5 in other detachable ways, such as: snap connection, etc.

[0031] In this embodiment, there are four counterweights 6, and the masses of the four counterweights 6 are 10g, 100g, 1kg and 2kg respectively. In other embodiments, the counterweights 6 can also be any other number, and the mass of each counterweight 6 can also be changed according to the detection standard corresponding to the material to be measured.

[0032] The lower end surface of the measuring head 7 is circular. In this embodiment, there are three measuring heads 7, and the diameters of the lower end surfaces of the three measuring heads 7 are 5 mm, 16 mm, and 35.7 mm, respectively. In other embodiments, there may be any other number of measuring heads 7, and their specific shapes and sizes may also be changed accordingly according to the detection standards corresponding to the materials to be measured.

[0033] The following table shows the measuring heads and counterweights used when measuring the thickness of several common packaging materials using this embodiment:

[0034]

[0035] like Figure 2 As shown, the thickness gauge for using various packaging materials further includes a lifting device, which is connected to the pressing center column 5 and is used to drive the pressing center column 5 to move in a direction away from the placement table 3. Normally, after the pressing center column 5 falls to the limit position, the measuring head 7 will be connected to the placement table 3; in actual operation, the pressing center column 5 is driven by the lifting device to move in a direction away from the placement table 3, thereby driving the measuring head 7 away from the placement table 3, so that the measured product can be placed on the placement table 3 for measurement.

[0036] Specifically, the lifting device includes a pressure rod 10, the middle part of which is hinged to the fixed base 1, one end of which is hinged to the downward pressing center column 5, and the other end is a free end extending out of the fixed base 1. When the product to be measured needs to be placed, the operator can press the pressure rod 10 to rotate the pressure rod 10 along the hinge with the fixed base 1, and the hinged end of the pressure rod 10 and the downward pressing center column 5 will push the downward pressing center column 5 to lift upward on the fixed base 1, thereby driving the measuring head 7 to move away from the placement table 3, so that an installation gap appears between the measuring head 7 and the placement table 3; then the operator can place the product to be measured on the placement table 3. Then release the pressure rod 10, and under the action of the self-gravity of the downward pressing center column 5 and the counterweight 6, the downward pressing center column 5 will rise and fall on the fixed base 1 until the measuring head 7 abuts against the product to be measured, and the thickness value of the current product to be measured can be known by reading the reading of the measuring instrument 4.

[0037] In other embodiments, the lifting device may also be other structures, as long as it can ensure that the downward pressing center column 5 can be lifted; for example: a lifting handle 2 is provided on the downward pressing center column 5, etc.

[0038] The method for measuring the thickness of packaging materials using the above-mentioned thickness gauge applicable to various packaging materials is as follows:

[0039] 1. First, calibrate the parallelism between the lower end surface of the measuring head 7 and the upper end surface of the placing table 3, so that the parallelism error between the lower end surface of the measuring head 7 and the upper end surface of the placing table 3 is within the detection standard range of the current product being tested. For example: the parallelism error when testing the thickness of pressure-sensitive tape should be less than or equal to 0.005 mm, and the parallelism error when testing the thickness of paper should not exceed 5 microns, etc. The specific calibration steps are:

[0040] Use a special parallelism gauge (a steel ball clamped by a metal sheet) and place it at the center and surrounding points between the two measuring surfaces. The extreme difference among the five readings is the parallelism error.

[0041] 2. According to the testing standard corresponding to the product to be measured, install the appropriate counterweight 6 and measuring head 7 onto the downward pressing center column 5.

[0042] Take the measurement of corrugated cardboard as an example: before measuring, a counterweight 6 with a mass of 2 kg is clamped onto the downward pressing center column 5 so that the counterweight 6 is in contact with the mounting platform 8; the original measuring head 7 on the downward pressing center column 5 is removed, and the measuring head 7 with a diameter of 35.7 mm is taken out, and the measuring head 7 is installed on the downward pressing center column 5 by inserting the connecting column 71 on the measuring head 7 into the connecting hole 51 in the downward pressing center column 5 and then tightening the measuring head 7.

[0043] 3. By pressing the pressure rod 10 to extend the free end of the fixed base 1, the pressure rod 10 rotates along the hinge with the fixed base 1. The hinged end of the pressure rod 10 and the downward pressure center column 5 will push the downward pressure center column 5 to move upward on the fixed base 1, thereby driving the downward pressure center column 5 and the measuring head 7 to move away from the placement table 3, so that an installation gap appears between the measuring head 7 and the placement table 3.

[0044] 4. Place the product to be tested on the placement table 3 so that it is placed flat on the placement table 3.

[0045] 5. Release the pressing force on the pressure rod 10. Under the action of the gravity of the downward pressing center column 5 and the counterweight 6, the downward pressing center column 5 will fall freely on the fixed base 1 until the measuring head 7 contacts the product to be measured.

[0046] 6. After standing for 2-5 seconds, record the data value on the current measuring instrument 4. The standing time is determined according to the specific conditions of different products under test. In principle, the data needs to be recorded before the product under test is "pressed" by the measuring head 7.

[0047] 7. Repeat the above steps 3-6 to measure different products under test and record the data. The number of repetitions is determined according to the testing standards of different products under test. However, no matter which product is under test, the number of repetitions should not be less than 3 times.

[0048] 8. Calculate the average value of each recorded data in step 6. This average value is the thickness value of the current measured product.

[0049] The above-mentioned specific implementation mode is a preferred implementation mode of the present utility model, and is not intended to limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to the specific implementation mode. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
