[0025] The continuous thickness measuring device of the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0026] The continuous thickness measuring device of the present application is suitable for measuring the thickness of aerogel felt. In order to facilitate the structural description of the continuous thickness measuring device, the conveying direction of the aerogel felt is defined as the front-to-back direction, and the width direction of the aerogel felt is defined as the left-to-right direction.

[0027] like Figure 1 As shown, a continuous thickness measuring device includes a mounting frame 1, and a plurality of measuring mechanisms for measuring the thickness of a workpiece are slidably mounted on the front side of the mounting frame 1. The measuring mechanisms include a transmission roller assembly 2 and a measuring roller assembly 3. A gap is left between the transmission roller assembly 2 and the measuring roller assembly 3. The workpiece is conveyed in the gap between the transmission roller assembly 2 and the measuring roller assembly 3 along the front-to-back direction to continuously measure the thickness of a point of the workpiece along all points in the feeding direction. In some embodiments, the user can select a suitable number of measuring mechanisms for installation according to actual needs to continuously measure the thickness of multiple points in the width direction of the workpiece along all points in the feeding direction, and this application does not limit this.

[0028] like Figure 2 As shown, the mounting frame 1 also includes two support plates 12, which are arranged opposite to each other, and the mounting seat is connected between the two support plates 12. In this embodiment, the upper and lower ends of the opposite surfaces of the two support plates 12 are provided with mounting grooves 121 for mounting the mounting seat 11, and the mounting seat 11 is installed inside the mounting groove 121 and abuts against the inner wall of the mounting groove 121. The outer surfaces of the two support plates 12 are both installed with first mounting bolts for mounting and fixing the mounting seat 11, which are not shown in the figure. The first mounting bolts pass through the support plates 12 and are threadedly installed inside the mounting seat 11. In other embodiments, the mounting seat 11 can also be connected to the support plate in other ways, or be integrally formed with the support plate, and this application does not limit this. A sliding groove 111 for installing the transmission roller assembly 2 or the measuring roller assembly 3 is provided inside the mounting seat 11. The transmission roller assembly 2 and the measuring roller assembly 3 are respectively installed in the sliding groove of the mounting seat at the bottom and the sliding groove of the mounting seat at the top. The sliding groove 111 extends along the length direction of the mounting seat 11 and is used by the user to adjust the position of the measuring mechanism along the sliding groove 111.

[0029] like Figure 3 As shown, the transmission roller assembly 2 includes two first mounting plates 21, the first mounting plates 21 are L-shaped, a first fixing bolt 22 is installed inside the first mounting plate 21, a first fixing nut is threadedly installed at one end of the first fixing bolt 22, a part of the first fixing bolt 22 and the first fixing nut are both slidably installed in the sliding groove 111 of the bottom mounting seat 11, and a first mounting shaft 24 is installed on the relative inner sides of the two first mounting plates 21 through the first mounting bolt 23, and a transmission roller 26 is rotatably installed on the first mounting shaft 24 through a first connecting bearing 25.

[0030] like Figure 3 As shown, the measuring roller assembly 3 is correspondingly arranged above the driving roller assembly 2, and the measuring roller assembly 3 includes a first fixed block 31, a guide rod assembly that moves up and down relative to the first fixed block 31, and a measuring roller 35 fixed to the lower end of the guide rod assembly. Second mounting plates 311 are fixedly installed on both sides of the first fixed block 31, and second fixing bolts 312 for mounting and fixing the second mounting plates 311 are installed inside the two second mounting plates 311, and a second fixing nut is threadedly installed on one end of the second fixing bolt 312. A part of the second fixing bolt 312 and the second fixing nut are slidably installed inside the sliding groove 111 of the top mounting seat 11, so that one side of the first fixed block 31 and the top mounting seat 11 stop each other, and the driving roller assembly 2 and the measuring roller assembly 3 are both slidably installed with the mounting seat 11, which can facilitate the user to adjust their positions.

[0031] A second fixed block 32 is fixedly installed on the other side of the first fixed block 31, and the number of the second fixed blocks 32 is two. A sensor 39 is fixedly installed on the other side of the first fixed block 31 through a first connecting bolt 391, and the sensor 39 is located between the two second fixed blocks 32. A reinforcement strip 393 for reinforcing the sensor 39 is fixedly installed on the outer surfaces of the two second fixed blocks 32 through the second connecting bolts 392. The end of the sensing probe of the sensor 39 and the connecting piece 351 stop against each other. It can be imagined that the probe of the sensor 39 can adopt an electronic or optical probe, that is, the probe of the sensor 39 does not stop against the connecting piece 351 to measure the position change of the connecting piece 351. The interiors of the two second fixed blocks 32 are provided with mounting holes 321 that pass through from top to bottom. The two second fixed blocks 32 are provided with mounting holes 321 that pass through from top to bottom. A sleeve 33 is fixedly installed inside the mounting hole 321 of the fixed block 32, and guide rod assemblies are slidably installed inside the two sleeves 33. The guide rod assembly includes two guide rods 34, and a connecting piece 351 is fixedly installed at the bottom end of the two guide rods 34. The bottom of the connecting piece 351 is provided with an opening, and the interiors of the corresponding two sides of the connecting piece 351 are mounted on the second mounting shaft 353 through third mounting bolts 352. A second connecting bearing 354 for mounting a measuring roller 35 is fixedly installed on the outer surface of the second mounting shaft 353. The positions of the measuring roller 35 and the transmission roller 26 are arranged correspondingly up and down, and a gap is formed between the measuring roller 35 and the transmission roller 26 for the workpiece to pass through. The measuring roller 35 drives the connecting piece 351 to rise when the workpiece passes, and the sensor 39 measures the displacement of the connecting piece 351, that is, the thickness of the workpiece.

[0032] In some embodiments, the measuring roller assembly 3 also includes an adjustment assembly, which includes an elastic member 36, an adjustment member, a fixed plate 341 and an adjustment block 37. In this embodiment, the elastic member 36 is a spring, one end of the two guide rods 34 passes through the two mounting holes 321 and is connected to the top of the connecting member 351, and the other end of the two guide rods 34 passes through the adjustment block 37 and is fixedly installed on the fixed plate 341. The elastic member 36 is sleeved on the outer surface of the guide rod 34 and abuts between the adjustment block 37 and the second fixed block 32. The adjustment member includes a handle 381 and a threaded rod 38. The threaded rod 38 is threadedly connected to the fixed plate 341, and the threaded rod 38 passes through the fixed plate and abuts against the adjustment block 37. The handle 381 is connected to one end of the threaded rod 38 away from the adjustment block 37, and is used to rotate the threaded rod 38.

[0033] During use, the handle 381 is turned to extend the threaded rod 38 toward the bottom to press down the adjustment block 37, and the measuring roller 35 is moved to a preset height (for example, if the thickness of the workpiece to be measured is about 1.2 mm, the measuring roller 35 is moved to a distance of 1 mm from the transmission roller 26). The elastic member 36 is prestressed by the adjustment block 37, so that the prestress of the elastic member 36 counteracts the elastic force of the spring connected to the sensing probe inside the sensor 39 and the gravity of the measuring roller and other components, and the distance between the measuring roller 35 and the transmission roller 26 is adjusted to ensure that the pressure on the workpiece meets the test standard when the workpiece passes, especially when the workpiece is a soft and deformable product, such as a fiber felt product. The height of the measuring roller 35 increases or decreases with the thickness of the workpiece, so that the sensor 39 accurately senses the thickness change of the workpiece, reduces the influence of the compression deformation of the aerogel felt on the measurement result, and thus achieves the purpose of continuously measuring the thickness of the workpiece conveyed between the transmission roller assembly 2 and the measuring roller assembly 3.

[0034] In the utility model, by respectively arranging mounting seats 11 at the top and bottom of the mounting frame 1 to install the measuring roller assembly 3 and the driving roller assembly 2, the workpiece can be transported between the driving roller assembly 2 and the measuring roller assembly 3, and a sensor 39 is arranged on the measuring roller assembly 3. When the height of the measuring roller 35 rises or falls with the thickness of the workpiece, the sensing probe of the sensor 39 is squeezed to different degrees, so that the sensor 39 can accurately sense the thickness change of the workpiece, thereby achieving the purpose of continuously measuring the thickness of the workpiece.

[0035] Finally, it should be noted that the above implementation modes are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred implementation modes, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
