Description

Technical Field

[0001] The present invention relates to the technical field of laser detection of triple-proof fabrics, in particular to a device for detecting the coating thickness of triple-proof fabrics. Background Art

[0002] Triple-proof fabric refers to specially treated fiber fabrics. The "triple-proof" in its name generally refers to its three basic functions: waterproof, fireproof, and mildew-proof. Its base material is mainly made of glass fiber cloth, glass cotton cloth, or chemical fiber cloth. A coating (coated with refractory materials such as PVC, PTFE, flame-retardant silicone, etc.) is added to the surface of the base material. Through a special coating process, it achieves multifunctional composite. It is mainly used in freight covers (car / train tarpaulins), equipment protective covers, fire protection suits, fire blankets, electric welding fire curtains, and the chemical industry. The coating thickness on the surface of the triple-proof fabric directly affects the protective effect. Therefore, unified testing of the coating thickness is required during processing to ensure coating uniformity, quickly screen for waterproof coating defects, and improve the durability of the triple-proof fabric products.

[0003] The utility model with announcement number CN215114417U discloses a spunlace non-woven fabric thickness monitoring device. A laser rangefinder is fixedly installed on the bottom outer wall of the installation shell, a PLC is fixedly installed in the inner cavity of the installation shell, a controller is fixedly connected to the top outer wall of the installation shell, and a display screen is fixedly installed on the top of the controller, which has the effect of more conveniently detecting the thickness of the spunlace non-woven fabric.

[0004] The utility model with announcement number CN219996108U discloses a wet glue thickness detector for a coating machine. By supporting the coated substrate and setting it in a box, the detection component detects the laser information blocked by the positioning roller, substrate, and liquid coating on the substrate, thereby obtaining the thickness information of the liquid coating on the substrate. The coating thickness of the liquid coating on the substrate is detected in real time during the substrate coating production, and unqualified products are dealt with in a timely manner, thereby improving product quality.

[0005] However, the above-disclosed laser detection device for fabric coating thickness still has the following problems during actual use: the fabric is placed inside a detection box and the thickness is detected by a laser beam. However, due to the soft material of the fabric, it curls up due to factors such as winding during the production process, and is prone to wrinkles when stacked and wound. Therefore, if the fabric is placed directly in the detection box, it is easy for wrinkles and curling to block the laser beam. At the same time, dust and dirt are easily attached during transportation and winding, and are squeezed and tightened during winding, thereby blocking the beam and affecting the detection data.

[0006] Therefore, we proposed a three-proof cloth coating thickness detection device to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a three-proof fabric coating thickness detection device to solve the problem that the existing method is to place the fabric inside a detection box and use a laser beam to perform thickness detection. However, due to the soft material of the fabric itself, it curls due to factors such as winding during the production and processing, and is prone to wrinkles when stacked and rolled. Therefore, if it is placed directly in the detection box, it is easy to block the laser beam due to wrinkles and curling. At the same time, it is easy for dust to adhere to it during transportation and winding, and it is squeezed and tightened during winding, thereby blocking the beam and affecting the detection data.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for detecting the coating thickness of a three-proof fabric, comprising a detection platform, and an unwinding unit and a rewinding unit fixedly installed on the left and right sides of the top surface of the detection platform; A detection assembly is fixedly installed on the right side of the top surface of the detection platform, and the detection assembly includes a detection base, and the detection base is a hollow structure so that the three-proof cloth passes through the inside of the detection base; Among them, laser detectors are fixedly installed on the front and back sides of the detection base.

[0013] Preferably, the dust removal mechanism includes a bidirectional screw, and the bidirectional screw is rotatably arranged on the left side of the bottom surface of the detection platform through a bearing, and the front end of the bidirectional screw and the front end of the dust removal roller below are connected to each other through a pulley assembly, and the front and rear outer walls of the bidirectional screw are both threadedly connected to the left end of the pushing bracket.

[0014] Preferably, the dust removal mechanism includes a dust collecting box fixedly installed on the front and rear sides of the bottom of the detection platform, and sealing plugs are slidably provided on the inner sides of the two dust collecting boxes, and the sealing plugs are fixedly connected to the right end of the pushing bracket, and one-way exhaust valves are provided on the outer sides of the bottom surfaces of the symmetrically arranged dust collecting boxes.

[0015] Preferably, the dust removal mechanism includes a one-way suction pipe connected to the top of the dust collecting box, and the upper end of the one-way suction pipe is connected to the inside of a symmetrically arranged adsorption hood. When the dust inside the adsorption hood is moved away from the one-way exhaust valve through the sealing plug plate inside the dust collecting box, the dust and dirt inside the adsorption hood are collected under negative pressure.

[0016] Preferably, a wrinkle removal mechanism is provided above the detection platform, and the wrinkle removal mechanism includes a wrinkle removal base fixedly installed in the middle of the top surface of the detection platform, and correction slide rails are fixedly installed on the left and right sides of the interior of the wrinkle removal base, and correction wheel seats are elastically slidably provided on the front and rear sides of the symmetrically arranged correction slide rails, and the correction wheel seats are fitted to the sides of the three-proof cloth to prevent it from being dislocated and offset during movement.

[0017] Preferably, the wrinkle removal mechanism includes a wrinkle removal inclined plate, and the outer end of the wrinkle removal inclined plate is rotatably mounted on the right outer wall of the correcting wheel seat through a torsion spring, and the interior of the symmetrically arranged wrinkle removal inclined plate is provided with wrinkle removal wheels that rotate at equal distances, and the wrinkle removal inclined plate is fitted on the upper and lower outer walls of the three-proof cloth, and the movement of the three-proof cloth drives the fitted wrinkle removal wheels to rotate, and the rotational force is transmitted to the three-proof cloth to achieve the smoothing of wrinkles.

[0018] Compared with the prior art, the present invention has the following advantages: the coating thickness detection device for three-proof fabric uses an unwinding unit and a rewinding unit to convey the three-proof fabric, and a dust removal mechanism to assist in cleaning and collecting attached dust. At the same time, a wrinkle removal mechanism corrects the deviation of the three-proof fabric and removes wrinkles, so that the flat three-proof fabric passes through the detection beam for coating thickness detection, thereby preventing factors such as dust, wrinkles, etc. from affecting the laser detection data. The specific contents are as follows: 1. The roll of the three-proof cloth is installed through the unwinding unit, and the tail end of the three-proof cloth is inserted into the dust removal mechanism, wrinkle removal mechanism and the inside of the detection base. Then, the tail end of the three-proof cloth is reeled in by the reeling unit, and the servo motor of the reeling unit drives the three-proof cloth to be reeled in, so that the three-proof cloth above the detection platform is transported and moved to facilitate the coating thickness detection.

[0019] 2. The meshing drive gear rotates, driving the dust removal rollers and dust removal brush plates on the upper and lower sides to rotate. The dust removal brush plates adhere to the surface of the three-proof cloth in the opposite direction to scrape off the attached dust and dirt. The scraped dust and dirt then adhere to the outer wall of the dust removal brush plate and follow the rotation of the dust removal roller away from the three-proof cloth, thereby preventing dust and dirt from accumulating and affecting the dust removal effect.

[0020] Furthermore, the rotating dust removal roller drives the reciprocating screw to rotate through the pulley assembly, and when the threaded pushing bracket is driven to move outward, the fixedly connected sealing plug plate draws air from the inside of the adsorption hood, and then the dust and dirt on the dust removal roller is attracted to the inside of the dust collecting box for storage.

[0021] Furthermore, during the reverse movement of the sealing plug plate, the air inside the dust collecting box is squeezed so that the air can be discharged through the provided one-way exhaust valve, and the movement of the sealing plug plate can guide the dust and dirt covered above the one-way exhaust valve to avoid affecting the dust collecting operation of the dust collecting box.

[0022] 3. The correcting wheel seat, which is elastically slidably arranged on the outer wall of the correcting rail, is located on the side of the three-proof fabric. It contacts the side of the three-proof fabric so that it is always in the center position, avoiding deviation during subsequent inspection and winding. At the same time, the wrinkle removal inclined plate is sleeved on the outer wall of the three-proof fabric, driving the wrinkle removal wheel to rotate and smoothing the wrinkles on the surface of the three-proof fabric.

[0023] 4. As the three-proof fabric moves and is transported inside the detection base, the laser detector adjusts the distance of the internal detection beam so that the detection beam is located on the upper and lower sides of the three-proof fabric coating. Three-proof fabric with thickness deviation will block the reception of the detection beam, so that the operator can mark it intuitively and accurately through the warning of the detection base.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] See also Figures 1-10 , the present invention provides the following technical solutions: Example 1: In order to solve the problems existing in the laser detection of the existing three-proof cloth coating, this embodiment discloses the following technical solution: a three-proof cloth coating thickness detection device, including a detection platform 1, and a reeling unit 2 and a reeling unit 3 fixedly installed on the left and right sides of the top surface of the detection platform 1; a detection component is fixedly installed on the right side of the top surface of the detection platform 1, and the detection component includes a detection base 4, and the detection base 4 has a hollow structure so that the three-proof cloth can pass through the inside of the detection base 4.

[0028] A dust removal mechanism is provided on the left side of the top surface of the detection platform 1, and the dust removal mechanism includes a dust removal bracket 7, and dust removal rollers 8 are provided on the upper and lower sides of the two dust removal brackets 7 for rotation through bearings; the outer walls of the dust removal rollers 8 included in the dust removal mechanism are fixedly installed with dust removal brush plates 9 at equal angles, and the three-proof cloth moves through the upper and lower dust removal rollers 8, and the dust removal brush plates 9 set at equal angles are attached to the upper and lower surfaces of the three-proof cloth to scrape off the dust and dirt on the surface of the three-proof cloth to avoid data deviation when the detection component performs laser detection.

[0029] The dust removal mechanism includes a driving gear 10, and the driving gear 10 is fixedly mounted on the front end of the upper and lower dust removal rollers 8, and the upper and lower driving gears 10 are engaged 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.

[0030] like Figure 1 As shown, during the laser inspection of the coating of the three-proof cloth, the unwinding unit 2 on the top surface of the inspection platform 1 first installs the three-proof cloth roll, and after the tail end of the three-proof cloth passes through the dust removal mechanism, wrinkle removal mechanism and inspection component, the tail end of the three-proof cloth is reeled in by the reeling unit 3, and the servo motor of the reeling unit 3 provides driving force, so that the three-proof cloth is moved and transported from left to right inside the dust removal mechanism, wrinkle removal mechanism and inspection component.

[0031] like Figure 3 、 Figure 6 As shown, when the three-proof cloth is moved and transported between the upper and lower dust-removing rollers 8, the drive motor installed on the rear dust-removing bracket 7 works, thereby driving the dust-removing roller 8 connected by the drive gear 10 to rotate in the opposite direction. At the same time, the dust-removing roller 8 fits the coating on the upper and lower sides of the three-proof cloth through the dust-removing brush plates 9 distributed at equal angles on the outer wall, and then the three-proof cloth scrapes off the attached dust and dirt in the opposite direction. The scraped dust and dirt then adheres to the outer wall of the dust-removing brush plate 9 and follows the rotation of the dust-removing roller 8 away from the three-proof cloth, thereby preventing dust and dirt from accumulating and affecting the conveying and dust removal effect.

[0032] Example 2: In order to solve the problems existing in the existing three-proof cloth coating during laser detection, this embodiment discloses the following technical solution. The dust removal mechanism includes 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 bracket 7, and the open ends of the symmetrically arranged adsorption cover 24 correspond to the dust removal roller 8 and the dust removal brush plate 9 on its outer wall, and the interior of the adsorption cover 24 is fixedly installed with an elastic bar 11, so that it collides with the dust removal brush plate 9 and vibrates off the attached dust.

[0033] The dust removal mechanism includes a bidirectional screw 12, and the bidirectional screw 12 is rotatably arranged on the left side of the bottom surface of the detection platform 1 through a bearing, and the front end of the bidirectional screw 12 is connected to the front end of the dust removal roller 8 below through a pulley assembly 13, and the front and rear outer walls of the bidirectional screw 12 are both threadedly connected to the left end of the pushing bracket 14; the dust removal mechanism includes a dust collecting box 15 fixedly installed on the front and rear sides of the bottom of the detection platform 1, and the inner sides of the two dust collecting boxes 15 are both slidably provided with a sealing plug plate 16 , and the sealing plug plate 16 is fixedly connected to the right end of the pushing bracket 14, and a one-way exhaust valve 17 is provided on the outer side of the bottom surface of the symmetrically arranged dust collecting box 15; the dust removal mechanism includes a one-way suction pipe 23 connected to the top of the dust collecting box 15, and 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 inside the dust collecting box 15 moves away from the one-way exhaust valve 17, the dust inside the adsorption cover 24 is collected under negative pressure.

[0034] like Figure 6-Figure 9 As shown, during the rotation of the dust removal roller 8 above the detection platform 1, the connected bidirectional screw 12 is driven to rotate by the pulley assembly 13, and the pushing bracket 14 and the sealing plug plate 16 threadedly connected to its outer wall are limited by the dust collecting box 15, thereby driving the pushing bracket 14 and the sealing plug plate 16 to slide back and forth inside the dust collecting box 15.

[0035] Furthermore, when the sealing plug plate 16 moves toward the outside of the dust collecting box 15, it sucks the air inside the dust collecting box 15, causing the interior to be in a negative pressure state, so that the air can be extracted from the inside of the adsorption cover 24 by the one-way suction pipe 23 connected through it, 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 collide with the elastic bar 11 inside the adsorption cover 24, thereby vibrating and shaking off the attached dust), so that the adsorption cover 24 in a negative pressure state will suck the cleaned dust and drive the dust into the interior of the dust collecting box 15 for storage for subsequent collection and processing.

[0036] Furthermore, when the sealing plug plate 16 moves toward the interior of the dust collecting box 15, the air inside the dust collecting box 15 is squeezed, and the air cannot be discharged through the one-way suction pipe 23 connected through it. The air is only discharged to the outside by the provided one-way exhaust valve 17. At the same time, when solid dust is stored inside the dust collecting box 15, the one-way exhaust valve 17 is easily covered by dust and affects the exhaust. When the moving sealing plug plate 16 approaches the one-way exhaust valve 17, the dust is peeled off through its comb-like structure to avoid affecting the dust collection operation of the dust collecting box 15.

[0037] Example 3: In order to solve the problems existing in the existing three-proof fabric coating during laser detection, this embodiment discloses the following technical solution: a wrinkle removal mechanism is provided above the detection platform 1, and the wrinkle removal mechanism includes a wrinkle removal base 18 fixedly installed in the middle of the top surface of the detection platform 1, and the wrinkle removal base 18 has correcting slide rails 19 fixedly installed on both the left and right sides thereof, and the front and rear sides of the symmetrically arranged correcting slide rails 19 are elastically slidably provided with correcting wheel seats 20, which are fitted to the side edges of the three-proof fabric to prevent it from being dislocated or offset during movement.

[0038] The wrinkle removal mechanism includes a wrinkle removal inclined plate 21, and the outer end of the wrinkle removal inclined plate 21 is rotatably mounted on the right outer wall of the correcting wheel seat 20 through a torsion spring, and the interior of the symmetrically arranged wrinkle removal inclined plate 21 is evenly rotated with a wrinkle removal wheel 22, and the wrinkle removal inclined plate 21 is fitted on the upper and lower outer walls of the three-proof cloth. The movement of the three-proof cloth drives the fitted wrinkle removal wheel 22 to rotate, and the rotational force is transmitted to the three-proof cloth to achieve wrinkle smoothing.

[0039] like Figure 3 、 Figure 10 As shown, the correcting wheel seats 20 arranged on the front and rear sides above the wrinkle-removing base 18 are located on the side of the three-proof cloth, and the correcting wheel seats 20 are tensioned by the elastically connected correcting slide rails 19, so that the correcting wheel seats 20 can always correct the three-proof cloth in a centered manner during the movement and transportation of the three-proof cloth, so as to prevent offset and misalignment during subsequent inspection and winding.

[0040] Furthermore, a wrinkle-removing inclined plate 21 is elastically arranged on the right side of the correcting wheel seat 20, which is sleeved and installed on the upper and lower sides of the edge of the three-proof fabric, and the wrinkle-removing wheels 22 equidistantly arranged inside the wrinkle-removing inclined plate 21 fit into the surface of the three-proof fabric, thereby driving the wrinkle-removing wheels 22 to rotate synchronously during the movement of the three-proof fabric, and can transmit the driving force of the rotation to the surface of the three-proof fabric to achieve wrinkle smoothing, thereby avoiding data deviation caused by wrinkle offset during subsequent detection.

[0041] Example 4: In order to solve the problems existing in the laser detection of the coating of the existing three-proof cloth, this embodiment discloses the following technical solution, wherein laser detectors 5 are fixedly installed on the front and back sides of the interior of the detection base 4, and the laser detector 5 detects the coating thickness of the three-proof cloth by emitting and receiving detection light beams 6 on the upper and lower sides of the three-proof cloth; the detection base 4 included in the detection component is used to penetrate the three-proof cloth, and the left end of the three-proof cloth is wound and installed on the outer wall of the unwinding unit 2, and the right end of the three-proof cloth is wound and installed on the outer wall of the winding unit 3. The three-proof cloth 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 detection light beam 6 emitted by the laser detector 5 is used to detect the thickness.

[0042] like Figure 1 、 Figure 4-Figure 5 As shown, after the three-proof cloth is processed by the dust removal mechanism and the wrinkle removal mechanism, its end, in the process of passing through the detection base 4, is detected by the laser detectors 5 symmetrically installed on the front and back sides of the detection base 4 corresponding to the side of the three-proof cloth, and then the distance is adjusted for the detection light beam 6 inside the laser detector 5 according to the coating thickness of the three-proof cloth of different specifications. Then, through the continuous transportation of the three-proof cloth, the detection light beam 6 is distributed on the upper and lower sides of the three-proof cloth, and the three-proof cloth with thickness deviation will block the reception of the detection light beam 6, so that the operator can mark it intuitively and accurately through the early warning of the detection base 4.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
