Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] Please refer to Figures 1-10 The present application provides the following technical solutions:

[0041] Embodiment 1: In order to solve the problems existing in the laser detection of the existing three-proof cloth coating, the technical scheme is disclosed in the embodiment, a three-proof cloth coating thickness detection equipment, comprising a detection platform 1, and a unwinding machine group 2 and a winding machine group 3 fixedly installed on the left and right sides of the top surface of the detection platform 1; the top surface of the detection platform 1 is fixedly installed with a detection assembly, and the detection assembly comprises a detection base 4, and the detection base 4 is in an inner hollow structure, so that the three-proof cloth penetrates through the inside of the detection base 4.

[0042] A dust removal mechanism is arranged on the left side of the top surface of the detection platform 1, and the dust removal mechanism comprises a dust removal support 7, and a dust removal roller 8 is rotatably arranged on the inside of the two dust removal supports 7 through bearings on the upper and lower sides; the outer wall of the dust removal roller 8 included in the dust removal mechanism is fixedly installed with dust removal brush plates 9 at equal angles, and the three-proof cloth moves through the dust removal rollers 8 on the upper and lower sides, and the dust removal brush plates 9 arranged at equal angles are attached to the upper and lower surfaces of the three-proof cloth, so as to scrape off the dust on the surface of the three-proof cloth, avoiding data deviation caused by laser detection of the detection assembly.

[0043] The dust removal mechanism comprises a drive gear 10, and the drive gear 10 is fixedly installed at the front end of the upper and lower dust removal rollers 8, and the drive gears 10 on the upper and lower sides are meshed with each other, driving the symmetrically distributed dust removal rollers 8 to rotate in opposite directions, and the rotation direction of the dust removal rollers 8 is opposite to the moving direction of the three-proof cloth, so as to scrape off dust and impurities.

[0044] As shown in Figure 1 , during the laser detection of the coating of the three-proof cloth, first, the three-proof cloth roll is installed by the unwinding machine group 2 on the top surface of the detection platform 1, and the tail end of the three-proof cloth penetrates through the dust removal mechanism, the wrinkle removal mechanism and the detection assembly, and then the tail end of the three-proof cloth is wound by the winding machine group 3, and the driving force is provided by the servo motor of the winding machine group 3, so that the three-proof cloth moves and is conveyed from left to right in the dust removal mechanism, the wrinkle removal mechanism and the detection assembly.

[0045] As shown in Figure 3 , Figure 6 , when the three-proof cloth moves and is conveyed between the upper and lower dust removal rollers 8, the drive motor installed on the rear dust removal support 7 works, thereby driving the dust removal rollers 8 connected through the drive gear 10 to rotate in the opposite direction, and the dust removal brush plates 9 distributed at equal angles on the outer wall of the dust removal roller 8 are attached to the coating on the upper and lower sides of the three-proof cloth, and then the dust attached to the three-proof cloth is scraped off in the opposite direction of the three-proof cloth, and the scraped dust is attached to the outer wall of the dust removal brush plate 9 and moves away from the three-proof cloth with the rotation of the dust removal roller 8, thereby preventing dust accumulation from affecting the conveying and dust removal effect.

[0046] In order to solve the problems existing in the laser detection of the existing three-proofing cloth coating, the dust removal mechanism comprises an adsorption cover 24, and the adsorption cover 24 is fixedly installed on the upper and lower sides of the right end of the dust removal support 7 and is symmetrically arranged. The open end of the adsorption cover 24 corresponds to the dust removal brush plate 9 distributed on the outer wall of the dust removal roller 8, and the elastic bars 11 are fixedly installed in the adsorption cover 24, so that the dust attached to the dust removal brush plate 9 is vibrated and shaken off.

[0047] The dust removal mechanism comprises a bidirectional screw rod 12, and the bidirectional screw rod 12 is rotatably arranged on the left side of the bottom surface of the detection platform 1 through a bearing. The front end of the bidirectional screw rod 12 is connected to the front end of the lower dust removal roller 8 through a belt pulley assembly 13, and the front and rear outer walls of the bidirectional screw rod 12 are threadedly connected to the left end of the push bracket 14. The dust removal mechanism comprises two dust collection boxes 15 fixedly installed on the front and rear sides of the bottom surface of the detection platform 1. The inner sides of the two dust collection boxes 15 are slidably provided with sealing plug plates 16, and the sealing plug plates 16 are fixedly connected to the right end of the push bracket 14. The bottom surfaces of the symmetrically arranged dust collection boxes 15 are provided with one-way exhaust valves 17. The dust removal mechanism comprises a one-way suction pipe 23 connected to the upper part of the dust collection box 15. The upper end of the one-way suction pipe 23 is connected to the inside of the symmetrically arranged adsorption cover 24. When the sealing plug plate 16 in the dust collection box 15 moves away from the one-way exhaust valve 17, the dust in the adsorption cover 24 is collected by negative pressure.

[0048] As shown in Figures 6-9 The dust removal roller 8 above the detection platform 1 rotates in the rotating process, drives the connected bidirectional screw rod 12 to rotate through the belt pulley assembly 13, and the push bracket 14 and the sealing plug plate 16 threadedly connected to the outer wall are limited by the dust collection box 15, and then drive the push bracket 14 and the sealing plug plate 16 to reciprocally slide in the inside of the dust collection box 15.

[0049] Further, when the sealing plug plate 16 moves to the outside of the dust collection box 15, it sucks the air in the dust collection box 15, so that the inside is in a negative pressure state. The air in the adsorption cover 24 is extracted by the through-connected one-way suction pipe 23, and the open end of the adsorption cover 24 corresponds to the rotating dust removal roller 8 (the rotating dust removal roller 8 and the dust removal brush plate 9, which collide with the elastic bars 11 in the adsorption cover 24, and then vibrate and shake off the attached dust), so that the adsorption cover 24 in the negative pressure state sucks the cleaned dust and drives the dust into the inside of the dust collection box 15 for storage, so as to be collected and processed subsequently.

[0050] Further, when the sealing plug plate 16 moves towards the inside of the dust collecting box 15, the air inside the dust collecting box 15 is squeezed and cannot be discharged through the through-connected one-way suction pipe 23, but is discharged to the outside only by the provided one-way exhaust valve 17. When solid dust is stored in the dust collecting box 15, the one-way exhaust valve 17 is easily covered by the dust, which affects the exhaust. When the sealing plug plate 16 moves close to the one-way exhaust valve 17, the dust is stripped by the comb-shaped structure of the sealing plug plate 16, so as to avoid affecting the dust collecting operation of the dust collecting box 15.

[0051] In order to solve the problems of the existing three-proofing cloth coating in laser detection, the embodiment discloses the following technical scheme, the upper side of the detection platform 1 is provided with a wrinkle removing mechanism, and the wrinkle removing mechanism comprises a wrinkle removing base 18 fixedly installed in the middle of the top surface of the detection platform 1, and the left and right sides of the inside of the wrinkle removing base 18 are fixedly installed with deviation correction guide rails 19, and the front and back sides of the symmetrically arranged deviation correction guide rails 19 are elastically and slidably provided with deviation correction wheel bases 20, and the deviation correction wheel bases 20 are attached to the side edges of the three-proofing cloth to avoid displacement deviation during movement.

[0052] The wrinkle removing mechanism comprises wrinkle removing inclined plates 21, the outer ends of the wrinkle removing inclined plates 21 are rotatably installed on the right side outer wall of the deviation correction wheel base 20 through torsion springs, and the inside of the symmetrically arranged wrinkle removing inclined plates 21 are rotatably provided with wrinkle removing rotating wheels 22 at equal distances, and the wrinkle removing inclined plates 21 are attached to the upper and lower side outer walls of the three-proofing cloth, and the wrinkle removing rotating wheels 22 attached to the three-proofing cloth are driven to rotate, so that the rotating force is transmitted to the three-proofing cloth to realize the flattening of the wrinkles.

[0053] As shown in Figure 3 , Figure 10 , the deviation correction wheel bases 20 arranged on the front and back sides of the wrinkle removing base 18 are located at the side edges of the three-proofing cloth, and the deviation correction wheel bases 20 are tensioned through the elastically connected deviation correction guide rails 19, so that the deviation correction wheel bases 20 can always be corrected in a centered manner during the movement and conveying of the three-proofing cloth, so as to avoid displacement deviation during subsequent detection and winding.

[0054] Further, the wrinkle removing inclined plates 21 elastically arranged on the right side of the deviation correction wheel base 20 are sleeved and installed on the upper and lower sides of the side edges of the three-proofing cloth, and the wrinkle removing rotating wheels 22 arranged at equal distances in the inside of the wrinkle removing inclined plates 21 are attached to the surface of the three-proofing cloth, so that the wrinkle removing rotating wheels 22 are driven to rotate synchronously during the movement of the three-proofing cloth, and the rotating driving force can be transmitted to the surface of the three-proofing cloth to realize the flattening of the wrinkles and avoid data deviation caused by wrinkle deviation during subsequent detection.

[0055] Example 4: To address the problems existing in the laser detection of the coating of the existing three-proof fabric, this example discloses the following technical solution: Laser detectors 5 are fixedly installed on both the front and rear sides of the detection base 4. The laser detectors 5 detect the coating thickness of the three-proof fabric by emitting and receiving detection beams 6 on the upper and lower sides of the three-proof fabric. The detection base 4 included in the detection assembly is used to pass through the three-proof fabric. The left end of the three-proof fabric is wound and installed on the outer wall of the unwinding unit 2, and the right end of the three-proof fabric is wound and installed on the outer wall of the winding unit 3. The three-proof fabric is transported and transferred by the unwinding unit 2 and the winding unit 3, so that it moves inside the detection base 4, and the thickness is detected by the detection beams 6 emitted by the laser detectors 5.

[0056] like Figure 1 , Figures 4-5 As shown, after being processed by the dust removal and wrinkle removal mechanisms, the end of the three-proof cloth passes through the detection base 4. Laser detectors 5, symmetrically installed on the front and rear sides inside the detection base 4, correspond to the sides of the three-proof cloth. Then, the distance of the detection beam 6 inside the laser detector 5 is adjusted according to the coating thickness of the three-proof cloth of different specifications. Then, through the continuous delivery of the three-proof cloth, the detection beam 6 is distributed on the upper and lower sides of the three-proof cloth. The three-proof cloth with thickness deviation will block the reception of the detection beam 6, so that the operator can intuitively and accurately mark it through the warning of the detection base 4.

[0057] 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.
