[0002] In the production process of thermal insulation materials, it is crucial to ensure that the thickness of the material meets specific standards. Traditional thickness detection methods often rely on manual measurement or simple mechanical measuring equipment. This inefficient detection method will limit the production speed and also affect the quality control of the final product.

[0045] During the inspection, the thermal insulation cotton is driven by the conveyor belt 33 and smoothly passes through the inspection hole 12 provided in the inspection box 11. As the thermal insulation cotton passes through the inspection hole 12, the inspection part 4 located at the top of the inspection hole 12 performs thickness inspection. At the initial position, the bottom of the front marking wheel 51 is released to the contact position with the conveyor belt 33. When the thermal insulation cotton passes through the bottom of the front marking wheel 51, the inspection frame 42 is lifted up, and the inspection slot 43 moves toward the top of the inspection block 41. At this time, the distance sensor 44 detects the change in the distance between the bottom of the inspection block 41 and the bottom of the inspection slot 43, and calculates the height of the thermal insulation cotton. In this way, the thickness of the thermal insulation cotton can be measured in real time and accurately when it passes continuously, ensuring that each part of the thermal insulation cotton meets the preset quality standards, thereby greatly improving production efficiency and product quality control.

[0046] The marking part 5 includes a front marking wheel 51 rotatably mounted on the bottom of the detection frame 42, a pressure assembly 52 mounted in the detection frame 42, and side marking assemblies 53 mounted on both sides of the front marking wheel 51, wherein when the detection frame 42 moves upward, the pressure assembly 52 fills the front marking wheel 51 with marking liquid and marks the surface of the insulation cotton.

[0047] The pressure assembly 52 includes a piston rod 521 fixed to the bottom of the detection block 41 and a liquid storage tube 522 opened on both sides of the bottom of the detection groove 43, the top of the liquid storage tube 522 extends into the detection groove 43, the bottom of the liquid storage tube extends to the outside of the detection frame 42, and a liquid inlet hole 523 is provided on the surface of the top extension part of the liquid storage tube 522, and a first spring 45 is fixed to the bottom of the detection block 41, and the bottom of the first spring 45 is fixed to the inner bottom of the detection groove 43.

At the same time, when the liquid inside the storage tube is insufficient, the detection frame 42 is pulled downward to separate the detection block 41 from the detection slot 43, and the marking liquid is replenished into the detection block 41. The marking liquid can enter the liquid storage tube 522 through the liquid inlet hole 523.

[0049] A first through hole 511 is provided in the middle of the front marking wheel 51, and a plurality of second through holes 512 are opened around the first through hole 511, the second through holes 512 are communicated with the first through hole 511, a limiting block 513 is fixed inside the second through hole 512, an injection tube 514 is installed on the limiting block 513, a push plate 515 is fixed at one end of the injection tube 514, and a marking cotton 516 is fixed at the other end of the injection tube 514, a second spring 517 is sleeved on the side of the injection tube 514 close to the push plate 515, wherein in the initial position, the marking cotton 516 is located in the second through hole 512, and connecting rods 54 are rotatably installed at both ends of the front marking wheel 51, the interior of the connecting rod 54 is hollow, the connecting rod 54 is communicated with the bottom of the liquid storage tube 522, and one end of the connecting rod 54 is communicated with the first through hole 511.

The piston rod 521 pushes the liquid in the liquid storage tube 522 to move downward, and the marking liquid in the liquid storage tube 522 is injected into the first through hole 511 through pressure, and flows into the second through hole 512 through the first through hole 511 respectively, and part of the liquid enters the marking cotton 516 through the liquid injection tube 514. At the same time, the marking liquid pushes the push plate 515 to move to one side and compresses the second spring 517, pushing the end of the marking cotton 516 to the outside of the second through hole 512 to contact the thermal insulation cotton, and marking the surface of the thermal insulation cotton.

When the thickness of the detection surface increases, the plug rod pushes the liquid in the liquid storage tube 522 to move downward, and the marking liquid in the liquid storage tube 522 is pressed into the connecting rod 54 and injected into the first hydraulic tube 533. The marking liquid in the first hydraulic tube 533 flows into the second hydraulic tube 536. The second hydraulic tube 536 pushes the push rod 537 to move to one side, and at the same time, the rotating rod shaft 538 moves in the strip groove 535, so that the side marking wheel 532 protrudes to the outside of the side groove 534 and contacts the side of the thermal insulation cotton. There is marking liquid on the side marking wheel 532 to mark the side of the thermal insulation cotton, which is convenient for subsequent management and checking of uneven positions.
