In the tobacco shred production process, tobacco materials are transferred and transported among the working procedures through a conveying device. The conveying device usually adopts a mesh belt or a vibrating groove, and the spreading thickness of the materials on the mesh belt or the vibrating groove has direct influence on the material flow of the downstream process. Therefore, during the production process, the thickness of the paving material of the material needs to be measured to ensure that the thickness of the paving material is within a standard thickness range.

As shown in fig. 1, the conveyor has a conveying surface 10, and the material is laid flat on the conveying surface 10 to be conveyed. The current method for measuring the thickness of the pavement comprises the following steps: after the process operation is stabilized and it is confirmed that the material is uniformly spread on the conveying surface 10, the operator cuts 6 dividing lines 20 on the conveying surface 10, the dividing lines 20 extend in the conveying direction of the conveying surface (the M direction as shown in fig. 1), and the dividing lines 20 are arranged at equal intervals in the width direction of the conveying surface 10 (the N direction as shown in fig. 1), the conveying surface 10 is divided into seven equal parts by the 6 dividing lines 20. Then, an operator inserts a ruler into the materials in the 2 nd, 4 th and 6 th equal parts, measures the thickness of the three materials, calculates the average value of the three measured data, and obtains the average thickness value of the materials. However, during this process, the operator needs to bend down to look at the ruler with the ruler inserted into the material to take a reading.

Referring to fig. 2 and 3, the thickness measuring tool provided in the present embodiment includes a mounting base 1, a measuring rod 2, and a magnet ring 4. Wherein the measuring rod 2 extends along a first direction (X direction as shown in fig. 2), the measuring rod 2 has a first end 21 and a second end 22, the first end 21 of the measuring rod 2 is connected with the mounting seat 1, and graduation marks 23 distributed along the first direction are arranged on the circumferential surface of the measuring rod 2.

When the thickness of the material on the conveying device needs to be measured, the operator inserts the second end 22 of the measuring rod 2 into the material 30, and in the process of continuously inserting the measuring rod 2 downwards, the first contact surface 41 of the magnet ring 4 contacts with the upper surface of the material 30 and slides upwards along the axis of the measuring rod 2 under the thrust action of the upper surface of the material 30. Referring to fig. 5, when the second end 22 of the measuring rod 2 contacts the conveying surface 10, the magnet ring 4 stops moving relative to the measuring rod 2, and the distance between the first contact surface 41 and the lower end of the measuring rod 2 is the thickness of the material 30 (as shown by the dimension H in fig. 5). The operator then pulls the measuring rod 2 out of the material 30, and during the pulling-out of the measuring rod 2, the magnet ring 4 is always attached to the measuring rod 2 and does not move in the axial direction generated by the measuring rod 2. When the measuring rod 2 is pulled out of the material 30, the operator can obtain the thickness value of the material 30 by reading the scale value corresponding to the edge of the first contact surface 41 on the measuring rod 2. This application is through setting up measuring stick 2 and adsorbing magnet ring 4 on measuring stick 2, can realize extracting the back with measuring stick 2 from material 30 and carry out the reading again, not only reduces the operation degree of difficulty, can also avoid the inaccurate problem of reading because of conveyor contacts with measuring stick 2 produced to improve the accuracy of testing result.

Further, referring to fig. 2 and 3, a contact plate 5 is fixedly connected to the circumferential surface of the magnet ring 4, a second contact surface 51 is provided on the contact plate 5, the second contact surface 51 faces the second end 22 of the measuring rod 2 and is perpendicular to the first direction, and the second contact surface 51 is flush with the first contact surface 41. Through setting up contact plate 5, can be at the in-process of inserting the measuring stick 2 material, make the upper surface of material contact with second contact surface 51 to increase the area of contact of magnet ring 4 and material, and then increase the upward thrust that the material was applyed in magnet ring 4, prevent that magnet ring 4 can't slide for measuring stick 2 because of magnet ring 4 attracts with measuring stick 2 mutually and lead to. Illustratively, the contact plate 5 may be circular, and a through hole is provided at the center of the contact plate 5, and the through hole is sleeved on the outer circumferential surface of the magnet ring 4 and fixedly connected with the magnet ring 4. Through setting up contact plate 5 into circularly, can make the circumference atress of magnet ring 4 even, prevent that magnet ring 4 from producing crooked because of the atress is uneven, lead to sliding card to be dund. Illustratively, the contact plate 5 is made of an aluminum alloy, which makes the contact plate 5 light in weight and less susceptible to damage.

Further, referring to fig. 2, the mounting base 1 is in a strip shape, the mounting base 1 extends along a second direction (Y direction as shown in fig. 2), the second direction is perpendicular to the first direction, the number of the measuring rods 2 is at least two, and the measuring rods 2 are sequentially arranged along the second direction. By providing a plurality of measuring bars 2, an operator can measure a plurality of material thicknesses along the width direction of the conveying surface 10 at one time, thereby improving the working efficiency and improving the accuracy of the measurement result by calculating the average value of the material thicknesses at all positions.

Further, referring to fig. 2, the length of the mounting base 1 in the first direction (as shown by a dimension L in fig. 2) is equal to the width of the conveying surface 10 of the conveying device, the number of the measuring rods 2 is 3, namely, a first measuring rod 31, a second measuring rod 32 and a third measuring rod 33, wherein the axis of the first measuring rod 31 is located at the center of the mounting base 1 in the first direction, the second measuring rod 32 and the third measuring rod 33 are respectively arranged at two sides of the first measuring rod 31 in the first direction, and the axial distance between the second measuring rod 32 and the first measuring rod 31 (as shown by a dimension L1 in fig. 2) and the axial distance between the third measuring rod 33 and the first measuring rod 31 (as shown by a dimension L2 in fig. 2) are both 2/7 of the length of the mounting base 1.

In the prior art, when it is desired to measure the thickness of material on the conveying surface 10, an operator makes 6 dividing lines 20 in the conveying surface 10, as shown in fig. 1. The dividing lines 20 extend in the conveying direction of the conveying surface (the M direction as shown in fig. 1), and the dividing lines 20 are disposed at equal intervals in the width direction of the conveying surface 10 (the N direction as shown in fig. 1), and the conveying surface 10 is divided into seven equal parts, respectively equal parts D1, D2, D3, D4, D5, D6, and D7, by 6 dividing lines 20. Then, an operator inserts a ruler into the materials in the positions of the parts D2, D4 and D6, measures the thickness of the three materials, calculates the average value of the three measured data, and obtains the average thickness value of the materials. However, since the conveying surface 10 is covered by the tobacco material and the conveying device moves continuously, it is difficult for the operator to divide the material on the conveying surface 10 into seven equal parts, which results in difficulty in determining the equal parts of D2, D4 and D6, and difficulty in operation of the operator.

The thickness measuring tool provided in this embodiment can avoid the problem of great difficulty in operation of an operator caused by difficulty in dividing the material on the conveying surface 10 into seven equal parts by the operator. In the present embodiment, when it is necessary to measure the thickness of the material, the operator holds the thickness measuring tool above the conveying surface 10, places the mount 1 in the width direction of the conveying surface 10, and as shown in fig. 4, makes the extending direction of the mount 1 coincide with the width direction of the conveying surface 10 and makes both ends of the mount 1 flush with both sides of the conveying surface 10. Because the first measuring rod 31 is arranged at the center of the mounting seat 1 in the first direction, and the axial distance between the second measuring rod 32 and the first measuring rod 31 and the axial distance between the third measuring rod 33 and the first measuring rod 31 are 2/7 of the length of the mounting seat 1, the second measuring rod 32, the first measuring rod 31 and the third measuring rod 33 are respectively opposite to the D2, D4 and D6 equal dividing positions on the conveying surface 10, so that an operator can accurately and quickly find the measuring positions without dividing the dividing line 20, the operation difficulty is reduced, and the working efficiency is improved.

Further, referring to fig. 3, the second end 22 of the measuring rod 2 is provided with a tip 24, the tip 24 having a conical shape, and the cross-sectional diameter of the tip 24 gradually decreases from a direction approaching the first end 21 to a direction separating from the first end 21. In the prior art, an operator inserts the ruler into the material to measure the thickness of the material, and the ruler is large in width, so that the cross section area of the ruler is large, the material is not easy to insert through the end face of the ruler, and the measurement result is inaccurate. According to the embodiment, the tip 24 is arranged, so that the measuring rod 2 can be inserted into the material 30 more easily, the operation difficulty is reduced, and meanwhile, the inaccuracy of a measuring result caused by the fact that the measuring rod 2 cannot be inserted into the bottom of the material 30 can be prevented. Specifically, for the convenience of operator reading, a scale mark may also be provided on the conical surface of the tip 24, as shown in fig. 5, for displaying the distance between the lower end of the tip 24 ("lower" orientation is the orientation indicated by arrow a in fig. 2) and the scale mark along the first direction. When the measuring rod 2 is inserted into a material of smaller thickness, the upper surface of the material may be aligned with the graduation marks on the tip 24, at which time the operator can obtain the thickness value of the material from the reading corresponding to the graduation marks. In some other applications, where the thickness of the material is greater, when the measuring stick 2 is inserted into the material of greater thickness, the upper surface of the material is located above the upper end of the tip 24 (the "upper" orientation is the orientation indicated by arrow B in fig. 2). Therefore, when measuring a material with a large thickness, the tip portion 24 may not be provided with a scale mark, but the scale mark 23 on the circumferential surface of the measuring rod 2 may display a scale value including the length of the tip portion 24 along the first direction, that is, the scale value corresponding to the scale mark located at the lowest part of the circumferential surface of the measuring rod 2 is the length of the tip portion 24 along the first direction.

Further, referring to fig. 2 and 3, the thickness measuring tool provided in this embodiment further includes a pulling rope 6, one end of the pulling rope 6 is connected to the mounting base 1, and the other end of the pulling rope 6 is connected to the magnet ring 4. By providing the traction rope 6, the magnet ring 4 can be prevented from falling off the measuring rod 2 and being lost. The length of the traction rope 6 is, for example, less than or equal to the length of the measuring rod 2.

Further, referring to fig. 2, the mounting seat 1 is a cuboid, a handle 7 is further provided on the mounting seat 1, and the handle 7 and the measuring rod 2 are respectively located on two opposite surfaces of the mounting seat 1. By providing the handle 7, an operator can hold the handle 7 to insert the measuring rod 2 into the material 30 or withdraw the measuring rod from the material 30, thereby facilitating the operation of the operator.
