[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 and Figure 2 This utility model discloses a thickness detection device for patch production, comprising a mounting frame 1, a conveyor belt 2 fixedly mounted on the mounting frame 1, a gantry frame 3 fixedly mounted on the upper end of the mounting frame 1, a detection roller 4 slidably mounted on the gantry frame 3, the detection roller 4 being located above the conveyor belt 2, drive rods 51 fixedly mounted at both ends of the detection roller 4, a measuring tooth 511 provided on one side of the drive rod 51, a transmission gear 52 rotatably mounted on the gantry frame 3, the transmission gear 52 meshing with the drive rod 51, an indicator needle 53 fixedly mounted on the transmission gear 52, the indicator needle 53 extending along the diameter direction of the transmission gear 52, and a measuring ruler 54 fixedly mounted on the mounting frame 1, with the indicator needle 53 pointing to the measuring ruler 54.

[0027] Specifically, by setting up a conveyor belt 2 and a liftable detection roller 4, when the patch follows the conveyor belt 2 past the detection roller 4, the detection roller 4 moves upward under the push of the patch, which in turn causes the measuring teeth 511 to drive the transmission gear 52 to rotate. The transmission gear 52 drives the indicator needle 53 to rotate, and the indicator needle 53 points to the scale of the measuring ruler 54 for reading.

[0028] In this way, the patch is continuously conveyed by the conveyor belt 2, and the thickness of the patch is displayed by the indicator needle 53 driven by the movement of the detection roller 4, which facilitates continuous detection of the thickness of the patch. At the same time, by setting the length of the indicator needle 53, the rotation effect of the transmission gear 52 is magnified, making it easier to obtain a clearer reading and improve accuracy.

[0029] In some feasible configurations, the mounting frame 1 is a rectangular support frame, the conveyor belt 2 is a commonly used transmission belt structure, the gantry frame 3 spans the conveyor belt 2, and rectangular mounting slots are provided on both sides of the gantry frame 3 to facilitate the installation of the drive rod 51. The detection roller 4 is a cylindrical roller, and the drive rod 51 is a cylindrical rod. The drive rod 51 is slidably installed in the mounting slot of the gantry frame 3. The transmission gear 52 is rotatably installed in the mounting slot and meshes with the measuring teeth 511 of the drive rod 51. The indicator needle 53 is fixedly installed on the side of the transmission gear 52. The measuring ruler 54 is semi-circular and bolted to the gantry frame 3, coaxial with the transmission gear 52. The lifting height of the detection roller 4 on the measuring ruler 54 is marked with a scale value.

[0030] As one specific embodiment of the thickness detection device for patch production provided in the application, please refer to Figure 3 The transmission gear 52 is coaxially fixedly connected to a large diameter gear 521, which meshes with a small diameter gear 522 that is rotatably mounted on the gantry frame 3. An angle sensor 523 is installed at the shaft of the small diameter gear 522.

[0031] Overall, by setting the large-diameter gear 521 to mesh with the small-diameter gear 522, the rotation of the transmission gear 52 is amplified, and the rotation of the small-diameter gear 522 is measured by the rotation angle sensor 523, thereby calculating the thickness of the patch. The rotation angle sensor 523 facilitates fully automated detection of the equipment.

[0032] In some feasible methods, an electric push rod can be installed at the end of the conveyor belt 2. When a defective patch is detected, it is pushed off the conveyor belt 2 by the electric push rod.

[0033] As another specific embodiment of the thickness detection device for patch production provided in the application, please refer to Figure 2 The drive rod 51 includes a telescopic adjustment rod 515, and a toothed rod portion 512 is fixedly installed on the upper end of the telescopic adjustment rod 515.

[0034] Depending on the specific application scenario, the height of the detection roller 4 can be easily adjusted and corrected by setting a telescopic adjustment rod 515.

[0035] Furthermore, the telescopic adjustment rod 515 includes an adjustment tube 513, with reverse threads at both ends of the adjustment tube 513, and adjustment screws 514 threadedly connected to both ends of the adjustment tube 513. The two adjustment screws 514 are respectively fixedly connected to the toothed rod portion 512 and the detection roller 4.

[0036] It should be understood that by setting up the adjusting tube 513 and the adjusting screw 514, the height of the detection roller 4 can be adjusted by rotating the adjusting tube 513 to make adjustment convenient.

[0037] In some feasible methods, an adjusting ring is installed in the middle of the adjusting pipe 513, and the part of the gantry 3 located on both sides of the conveyor belt 2 is square rod-shaped, with rectangular holes opened on the side of the square rod, and the side of the adjusting ring protruding from the side of the square rod to facilitate adjustment.

[0038] As another specific embodiment of the thickness detection device for patch production provided in the application, please refer to Figure 1 The mounting frame 1 is fixedly installed with a liner 21 at the position of the gantry 3. The liner 21 is located below the conveyor belt 2 and supports the conveyor belt 2 to transport the patch.

[0039] It should be understood that by setting the liner 21, the conveyor belt 2 can be kept from sagging when passing the detection roller 4, thereby improving the detection accuracy.

[0040] Furthermore, the conveyor belt 2 and the liner 21 are porous, and an air suction pipe 22 is fixedly installed below the liner 21. The air suction pipe 22 is connected to an air suction device.

[0041] It should be understood that by setting the suction pipe 22, after the patch enters the liner 21, the patch is drawn downward through the suction pipe 22, which increases the friction between the patch and the conveyor belt 2 and reduces the possibility that the patch will be blocked by the detection roller 4 and cannot pass through the detection roller 4.

[0042] In some feasible embodiments, the liner 21 is rectangular and the suction pipe 22 is connected to a suction fan or other device that can provide negative pressure.

[0043] As another specific embodiment of the thickness detection device for patch production provided in the application, the detection roller 4 includes a fixed shaft 41, a roller portion 42 is rotatably mounted on the outside of the fixed shaft 41, and both ends of the fixed shaft 41 are connected to the drive rod 51.

[0044] It should be understood that by providing the rotatable ground roller 42, the adhesive can pass under the detection roller 4 without being blocked by the detection roller 4.

[0045] In some feasible ways, the detection roller 4 and the drive rod 51 can be made of materials such as aluminum or engineering plastics that can reduce weight while maintaining rigidity. Meanwhile, the roller 42 can be set to be hollow so that the adhesive can be lifted by the force of the conveyor belt 2 moving forward.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
