[0002] With the development of modern industry, roller coating technology has been widely used in the surface treatment of various substrates such as film, paper, metal plate, etc. This technology uses the pressure and friction of the roller to evenly apply the coating on the surface of the substrate to form the required coating thickness and density, and then produce a variety of products such as conductive film, insulating film, waterproof coiled material and composite film. However, in the roller coating production process, how to accurately and efficiently measure the thickness of the coating has always been one of the key factors restricting product quality and production efficiency.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Figure 1 and Figure 2 As shown, the laser thickness gauge for the roll coating production line includes a roll coater 100 , a guide roller 101 , a cleaning mechanism 110 , a winder 300 and a laser thickness measuring mechanism 200 .

[0035] The roller coater 100 is used to evenly coat the coating on the surface of the substrate, and apply a certain pressure and friction to the coated substrate through the roller to form a uniform coating and achieve the required thickness and density, thereby obtaining a product (such as a conductive film, an insulating film, a waterproof roll, a PET / PE composite film or a BOPP / PE composite film, etc.). The specific structure and working principle of the roller coater 100 are existing mature technologies and will not be repeated here.

[0036] The guide roller 101 is installed on the roll coater 100 ; the cleaning mechanism 110 is installed on the roll coater 100 , and the cleaning mechanism 110 is used to clean the guide roller 101 ; the winder 300 winds up the product processed by the roll coater 100 .

[0037] The laser thickness measuring mechanism 200 is located between the roller coating machine 100 and the winder 300, and is used to measure the thickness of the product processed by the roller coating machine 100. The laser thickness measuring mechanism 200 includes a bottom plate 201, a rotating rod 203, a laser thickness measuring assembly 210, a driving assembly 220, and a cleaning assembly 230. The rotating rod 203 is rotatably mounted on the top surface of the bottom plate 201; the laser thickness measuring assembly 210 is mounted on the upper end of the rotating rod 203, and the laser thickness measuring assembly 210 includes a first laser displacement sensor 216 and a second laser displacement sensor 217; the driving assembly 220 is used to drive the first laser displacement sensor 216 and the second laser displacement sensor 217 to reciprocate horizontally; and the cleaning assembly 230 is used to clean the first laser displacement sensor 216 and the second laser displacement sensor 217.

[0038] Specifically, the product produced by the roller coater 100 is brought into contact with the guide roller 101, passes through the laser thickness measuring assembly 210, and is finally wound on the winding roller of the winding machine 300. The operation of the winding machine 300 puts the product in a taut state.

[0039] By starting the first laser displacement sensor 216 and the second laser displacement sensor 217, the first laser displacement sensor 216 and the second laser displacement sensor 217 respectively measure the position of the upper surface and the lower surface of the product, and obtain the thickness of the product at a single point by calculation. Then, by starting the driving mechanism, the first laser displacement sensor 216 and the second laser displacement sensor 217 are driven to move horizontally, so that the first laser displacement sensor 216 and the second laser displacement sensor 217 can perform multi-point thickness measurement on the product, thereby improving the accuracy of the measurement.

[0040] like Figure 3 and Figure 4 As shown, the cleaning mechanism 110 includes a fixed plate 111, two telescopic rods 112, a tray 113, a collection box 114, a scraper 115 and a first slot 116. The fixed plate 111 is mounted on the roller coating machine 100; the two telescopic rods 112 are mounted on the top surface of the fixed plate 111, and the tray 113 is fixedly connected to the extended ends of the two telescopic rods 112; the telescopic rods 112 have damping, which can keep the tray 113 at a fixed height. The collection box 114 is placed on the tray 113, and the top of the collection box 114 is open; the scraper 115 is installed in the collection box 114, and the scraper 115 contacts the guide roller 101; the first slot 116 is opened on the side of the collection box 114.

[0041] Specifically, the collection box 114 is placed on the tray 113, and then the tray 113 is moved upward to make the scraper 115 contact the guide roller 101; when the guide roller 101 rotates, the scraper 115 scrapes the surface of the guide roller 101, thereby cleaning the dust and debris attached to the surface of the guide roller 101. A certain amount of water can also be poured into the collection box in advance, and when the shoveled dust contacts the water, the dust can be prevented from being raised.

[0042] like Figure 5 As shown, the laser thickness measuring mechanism 200 further includes a gear ring 204, a first mounting groove 205 and a tooth plate 206. The gear ring 204 is mounted on the outer surface of the rotating rod 203; the first mounting groove 205 is provided on the top surface of the bottom plate 201; one end of the tooth plate 206 is provided with teeth, the tooth plate 206 is plugged into the first mounting groove 205, and the tooth plate 206 is engaged with the gear ring 204.

[0043] Specifically, when the tooth plate 206 is located in the first mounting groove 205 and engages with the tooth ring 204, the rotating rod 203 cannot be rotated. When the tooth plate 206 is separated from the tooth ring 204, the tooth ring 204 continues to restrict, and the rotating rod 203 can be rotated.

[0044] like Figure 6 and Figure 7 As shown, the laser thickness measuring assembly 210 includes a box body 211, two through slots 212, a first mounting block 213, a second mounting block 214 and a second slot 218. The box body 211 is fixedly connected to the upper end of the rotating rod 203; the two through slots 212 are both provided on the box body 211; the first mounting block 213 and the second mounting block 214 are both provided with a slide slot 215, the first mounting block 213 is slidably connected to the through slot 212 located above, and the first laser displacement sensor 216 is installed on the bottom surface of the first mounting block 213; the second mounting block 214 is slidably connected to the through slot 212 located below, and the second laser displacement sensor 217 is installed on the top surface of the second mounting block 214; the second laser displacement sensor 217 is located directly below the first laser displacement sensor 216. The second slot 218 is provided on the bottom surface of the box body 211.

[0045] Specifically, when the first mounting block 213 and the second mounting block 214 are moved, the first laser displacement sensor 216 and the second laser displacement sensor 217 are driven to move horizontally along the through slot 212 .

[0046] like Figure 7As shown, the driving assembly 220 includes two reciprocating screws 221, two moving seats 222, two sprocket wheels, a chain 223 and a motor 224. The two reciprocating screws 221 are both rotatably connected to the inner wall of the box body 211; the two moving seats 222 are respectively sleeved on the two reciprocating screws 221, and the two moving seats 222 are respectively installed on the first mounting block 213 and the second mounting block 214; the two sprocket wheels are respectively sleeved on the two reciprocating screws 221; the chain 223 is sleeved on the two sprocket wheels; the motor 224 is installed on the box body 211, and the power output shaft of the motor 224 is fixedly connected to any reciprocating screw 221.

[0047] Specifically, when the motor 224 is running, the power output shaft of the motor 224 will drive a reciprocating screw 221 to rotate, and under the influence of the sprocket and the chain 223, the other reciprocating screw 221 will also rotate synchronously. When the two reciprocating screws 221 rotate, they will drive the two moving seats 222 to move back and forth horizontally, thereby driving the first mounting block 213 and the second mounting block 214 to move, thereby driving the first laser displacement sensor 216 and the second laser displacement sensor 217 to move horizontally along the through groove 212.

[0048] like Figure 8 As shown, the cleaning assembly 230 includes a hollow box 238, two air outlet grooves 239, a high-pressure gas tank 235, an air delivery pipe 236 and a valve 237. The hollow box 238 is mounted on the box body 211; the two air outlet grooves 239 are both provided on the hollow box 238, and the two air outlet grooves 239 are respectively facing the first laser displacement sensor 216 and the second laser displacement sensor 217; the high-pressure gas tank 235 is mounted on the box body 211; one end of the air delivery pipe 236 is connected to the high-pressure gas tank 235, and the other end of the air delivery pipe 236 is connected to the hollow box 238; the valve 237 is mounted on the air delivery pipe 236.

[0049] Specifically, when the first laser displacement sensor 216 and the second laser displacement sensor 217 are close to the hollow box 238, the valve 237 is opened so that the air in the high-pressure gas tank 235 quickly enters the hollow box 238 through the gas pipe 236, and the air in the hollow box 238 will be quickly ejected through the two air outlet grooves 239. The air ejected from the two air outlet grooves 239 will blow toward the first laser displacement sensor 216 and the second laser displacement sensor 217, thereby cleaning the surfaces of the first laser displacement sensor 216 and the second laser displacement sensor 217, thereby preventing dust from affecting the operation of the first laser displacement sensor 216 and the second laser displacement sensor 217, thereby ensuring the measurement accuracy.

[0050] like Figure 8As shown, the cleaning assembly 230 also includes a piston cylinder 231, an air inlet pipe 2311, an air outlet pipe 2312, a push plate 232, a spring 233 and a cam 234. The piston cylinder 231 is mounted on the top surface of the housing 211, a piston sheet is slidably connected inside the piston cylinder 231, a piston rod is mounted on the bottom surface of the piston sheet, the piston rod penetrates the bottom surface of the piston cylinder 231 and is slidably connected to the piston cylinder 231; the air inlet pipe 2311 is mounted on the top of the piston cylinder 231; the air outlet pipe 2312 is mounted on the top of the piston cylinder 231, and the other end of the air outlet pipe 2312 is connected to the high-pressure gas tank 235; both the air inlet pipe 2311 and the air outlet pipe 2312 are equipped with a one-way valve, so that the outside air can only enter the piston cylinder 231 in one direction through the air inlet pipe 2311, and the air in the piston cylinder 231 can only be discharged through the air outlet pipe 2312.

[0051] The push plate 232 is fixedly connected to one end of the piston rod outside the piston cylinder 231; one end of the spring 233 is fixedly connected to the push plate 232, and the other end of the spring 233 is fixedly connected to the bottom surface of the piston cylinder 231; the cam 234 is fixedly sleeved on the reciprocating screw 221 located above, and the cam 234 contacts the bottom surface of the push plate 232.

[0052] Specifically, when the push plate 232 moves upward, it drives the piston rod and the piston plate to move upward, and then the air in the piston cylinder 231 is transported to the high-pressure gas tank 235 through the air outlet pipe 2312; when the push plate 232 moves downward, it drives the piston rod and the piston plate to move downward, and then the outside air is sucked into the piston cylinder 231. With the cooperation of the rotating cam 234 and the spring 233, the piston cylinder 231 continuously sucks the outside air and continuously transports the air to the high-pressure gas tank 235.

[0053] Working principle: Before specific use, the collection box 114 is placed on the tray 113, and then the tray 113 is moved upward to make the scraper 115 contact with the guide roller 101.

[0054] During specific use, the product discharged from the roller coater 100 is brought into contact with the guide roller 101, then passes through the laser thickness measuring assembly 210, and is finally wound around the winding roller of the winder 300. The operation of the winder 300 puts the product in a taut state.

[0055] By starting the first laser displacement sensor 216 and the second laser displacement sensor 217, the first laser displacement sensor 216 and the second laser displacement sensor 217 perform single-point thickness measurement on the product, and then, by starting the motor 224, the power output shaft of the motor 224 will drive a reciprocating screw 221 to rotate, and under the influence of the sprocket and the chain 223, the other reciprocating screw 221 will also rotate synchronously. When the two reciprocating screws 221 rotate, they will drive the two moving seats 222 to reciprocate horizontally, and then drive the first mounting block 213 and the second mounting block 214 to move, and then drive the first laser displacement sensor 216 and the second laser displacement sensor 217 to move horizontally along the through slot 212, so that the first laser displacement sensor 216 and the second laser displacement sensor 217 perform multi-point thickness measurement on the product, thereby improving the accuracy of measurement.

[0056] When the reciprocating screw 221 at the top rotates, the cam 234 is driven to rotate. The rotating cam 234 cooperates with the spring 233 to continuously inhale the external air into the piston cylinder 231 and continuously deliver the air into the high-pressure gas tank 235. When the first laser displacement sensor 216 and the second laser displacement sensor 217 need to be cleaned, the first laser displacement sensor 216 and the second laser displacement sensor 217 are moved to the position of the hollow box 238, and then the valve 237 is opened, so that the air in the high-pressure gas tank 235 quickly enters the hollow box 238 through the air delivery pipe 236, and the air in the hollow box 238 is quickly ejected through the two air outlet grooves 239. The air ejected from the two air outlet grooves 239 is blown toward the first laser displacement sensor 216 and the second laser displacement sensor 217, so that the surface of the first laser displacement sensor 216 and the second laser displacement sensor 217 is cleaned, and dust is prevented from affecting the operation of the first laser displacement sensor 216 and the second laser displacement sensor 217, thereby ensuring the measurement accuracy.

[0057] When the guide roller 101 rotates, the scraper 115 will scrape the surface of the guide roller 101, thereby cleaning up the dust and debris attached to the surface of the guide roller 101, preventing the dust on the guide roller 101 from adhering to the product, thereby avoiding affecting the accuracy of thickness measurement.

[0058] Example 2: Figure 3 , Figure 5 , Figure 6 , Fig. 9 and Fig.10 As shown, when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0059] The laser thickness measuring mechanism 200 further includes a plurality of moving wheels 202 and a second mounting groove 207. The plurality of moving wheels 202 are all mounted on the bottom surface of the bottom plate 201, and the moving wheels 202 have a self-locking function. The second mounting groove 207 is provided on the top surface of the bottom plate 201, and the collecting box 114 is plugged into the second mounting groove 207. The tooth plate 206 is plugged into the first slot 116 and the second slot 218.

[0060] Working principle: When the laser thickness measuring mechanism 200 needs to be moved, the tray 113 is moved downward to drive the collecting box 114 to move downward, so that the collecting box 114 is away from the guide roller 101, and then the collecting box 114 is removed from the tray 113, and then the dust and debris in the collecting box 114 are poured out, and then the collecting box 114 is rotated so that the first slot 116 on the collecting box 114 faces upward, and then the collecting box 114 is inserted into the second mounting slot 207.

[0061] Then take the tooth plate 206 out of the first mounting groove 205 so that the tooth plate 206 is separated from the gear ring 204, and then rotate the rotating rod 203 so that the box body 211 is located directly above the collection box 114, so that the first slot 116 on the box body 211 is located directly above the second slot 218, and then, connect the tooth plate 206 with the first slot 116 and the second slot 218, so that the collection box 114 and the tooth plate 206 support the box body 211, and also make the collection box 114 and the tooth plate 206 limit the box body 211, so that the box body 211 cannot be rotated.

[0062] Finally, the plurality of moving wheels 202 are unlocked, so that the laser thickness measuring mechanism 200 can be easily pushed, thereby improving the flexibility of the laser thickness measuring mechanism 200.

[0063] And because the collecting box 114 and the tooth plate 206 support the box body 211, when the mobile laser thickness measuring mechanism 200 encounters a bumpy road section, it can also prevent the connection between the box body 211 and the rotating rod 203 from loosening, thereby ensuring the stability of the box body 211, and then ensuring the stability of the first laser displacement sensor 216, the second laser displacement sensor 217 and the motor 224, avoiding damage to the first laser displacement sensor 216, the second laser displacement sensor 217 and the motor 224.
