Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of composite material manufacturing, in particular to a high-strength coated tape coating process and a coating resin device. BACKGROUND

[0002] In many industrial fields, the performance requirements for materials are increasing, and traditional coated tapes often have deficiencies in strength, corrosion resistance, wear resistance, etc., and cannot meet the complex use requirements of modern industry, so it is necessary to coat resin on the coated tape through a resin coating device. The resin can bring specific functions to the cloth roll, such as waterproofing, fireproofing, and insulation. At the same time, resin coating can make the cloth roll surface more smooth and flat, improve the appearance quality, and improve the product's aesthetic and market competitiveness.

[0003] In the working process of the existing resin coating device, the square cloth is fed from the unwinding shaft and guided by the cloth guide roller to pass through each component in turn. The glue tank provides resin for the square cloth, and the roller evenly applies the resin to the square cloth. After roller coating is completed, the square cloth needs to be wound. When the sensor prompts that the square cloth is used up, a new square cloth disc is installed in time, and the continuity of the cloth is ensured through overlapping and double-sided adhesive bonding. During the overlapping operation, if manual operation is stopped, the humidity environment in the dehumidification box will change rapidly, which destroys the original stable process humidity conditions, and the quality of some humidity-sensitive fiber cloth products will be greatly reduced. Secondly, the operator may accidentally wrinkle the cloth or cause the cloth to deviate during cloth splicing, which affects the flatness of the cloth and the smooth passage of the cloth in the subsequent guide roller and other components.

[0004] Therefore, it is necessary to provide a high-strength coated tape coating process and a coating resin device to solve the above technical problems. SUMMARY

[0046] As Figures 1-5As shown, the present application provides a technical scheme: a high-strength coated tape coating resin device, including roller coating box 1, roller coating seat 12, pay-off roll 13, guide roll 14, extrusion roll 15, cloth roll 16, coating liquid tank 17 and overlapping assembly 2, the top of roller coating box 1 is provided with a dehumidification pipe, open the dehumidification unit, until the dew point in the roller coating unit ≤-35°C, open the hot water circulation tank half an hour in advance, and open the circulating water, the water tank temperature is set to 60°C, the number of roller coating seat 12 is two, and it is clamped and installed on one side of roller coating box 1, pay-off roll 13 is arranged above two roller coating boxes 1, the number of guide roll 14 is multiple, and it is rotatably installed on roller coating box 1, the number of extrusion roll 15 is two, and it is rotatably installed on roller coating box 1, cloth roll 16 is rotatably installed on the side of roller coating box 1 away from pay-off roll 13, a motor for driving cloth roll 16 to rotate is installed on roller coating box 1, after roller coating is completed, the checkered cloth collected by cloth roll 16 is manually supplemented and cut, the cloth roll is wrapped with plastic film and then put into an aluminum foil bag, it should be noted that the inner wall surface of the aluminum foil bag sealing portion cannot have residual resin, coating liquid tank 17 is clamped and installed above roller coating box 1 and above one of guide roll 14, overlapping assembly 2 is arranged above roller coating seat 12 and used for quickly overlapping the ends of two checkered cloths, overlapping assembly 2 comprises two mutually clamped and installed roll frame 21, the two roll frames 21 are oppositely and symmetrically arranged, pay-off roll 13 is clamped and installed on the lower roll frame 21, photoelectric sensors are installed on the opposite sides of the two lower roll frames 21, an installation roll 22 is clamped and installed in the upper roll frame 21, a stepping motor is installed on the installation roll 22 and used for rotating the installation roll 22, which is convenient for the later extension of the end of the checkered cloth, opposite fixed frames 23 are arranged above the two roller coating seats 12, the fixed frame 23 has an L-shaped structure, a first electric push rod 24 is installed on the horizontal end of the fixed frame 23, a suction accessory 25 is arranged below the first electric push rod 24, an air compressor 250 is arranged on the top of the suction accessory 25, a through hole is formed in the top of roller coating seat 12, a control seat 26 is slidably arranged in the through hole and moves along the left-right direction, the control seat 26 has a U-shaped structure, a matching roll 27 is rotatably installed on the top of the end of the control seat 26 away from roller coating seat 12, second electric push rods 28 are installed on the front and back ends of the control seat 26, a control roll 29 is rotatably installed between the moving ends of the two second electric push rods 28, U-shaped placing frames 291 are installed above the two roller coating seats 12, two spring telescopic rods 292 are installed on roller coating box 1, buffer rolls 293 are rotatably installed on the top of the spring telescopic rods 292, and the two buffer rolls 293 are arranged between guide roll 14.

[0047] It should be noted that the gauze is installed on the unwinding roller 13, and the take-up roller 16 starts to rotate for winding. After the gauze comes out of the unwinding roller 13, it is transmitted and guided through multiple cloth guide rollers 14. When passing under the coating liquid tank 17, the coating resin liquid in the coating liquid tank 17 flows to the passing gauze for coating. The gauze is coated more uniformly and fully on the gauze through the contact with the cloth guide roller 14 and the extrusion of the extrusion roller 15;

[0048] When the photoelectric sensor prompts that the gauze is used up, before a new gauze disc is installed, the new gauze is sleeved on the installation roller 22, and the double-sided adhesive tape is attached to the end surface of the new gauze. Then the end of the gauze is placed on the suction accessory 25, and the gauze is sucked under the negative pressure action of the air compressor 250. When the gauze is detected by the photoelectric sensor, the control roller 29 is driven downward by the second electric push rod 28. At this time, the gauze passing through the control roller 29 and the cooperating roller 27 is pressed. When the overlapping part is in the dehumidifying tank, the motor cannot be stopped. The gauze continues to move. During the movement of the gauze, the interval buffer roller 293 is pressed downward by the gauze. At this time, the spring telescopic rod 292 is gradually compressed. During the compression of the spring telescopic rod 292, a certain time is created for the overlapping operation of the overlapping assembly 2. The specific overlapping operation is that the suction accessory 25 is moved downward by the first electric push rod 24. The end of the new gauze and the original gauze pressed together through the double-sided adhesive tape. At this time, the first electric push rod 24 and the second electric push rod 28 are reset. The pressed spring telescopic rod 292 can be gradually reset. The new gauze and the end of the previous cloth are overlapped. Through the overlapping assembly 2 and the related automatic operation, the new cloth can be overlapped quickly when the gauze is used up. The production interruption caused by stopping and replacing is avoided. The production efficiency is greatly improved. Compared with manual operation, the position and force of overlapping can be more accurately controlled. The quality and reliability of overlapping are improved. At the same time, the quick and efficient overlapping process also saves time and labor cost.

[0049] It is worth noting that when the cloth is adsorbed by the suction accessory 25, the first electric push rod 24 moves the suction accessory 25 downward. In order to prevent the gauze from deviating during the downward movement of the suction accessory 25, the negative pressure of the air compressor 250 needs to be greater than the rotating force of the installation roller 22. This is beneficial to the downward movement of the gauze in the suction accessory 25, which plays a stabilizing role.

[0050] As Figure 4 and Figure 6As shown, the suction accessory 25 comprises a suction seat 251, which is in a concave structure, and a first limiting groove 252 is arranged at the front and rear ends of the suction seat 251. A suction frame 253 is slidably connected to the inner side of the suction seat 251. A limiting block 254 is arranged on the inner side of the suction frame 253. A linear array of expansion springs 255 is arranged between the top of the suction frame 253 and the inner side of the suction seat 251. A rectangular array of suction holes 256 is arranged at the bottom of the suction frame 253, and one end of the suction hole 256 is connected with the air outlet end of the air compressor 250.

[0051] It should be noted that the suction accessory 25 starts to move upwards, and at the same time, the air compressor 250 stops working and the negative pressure stops. At this time, there is no suction effect of the negative pressure on the square cloth. The compressed linear array of expansion springs 255 starts to release the elastic force to push the suction frame 253 to slide downwards in the suction seat 251 (slide along the predetermined track under the cooperation of the first limiting groove 252 and the limiting block 254). The suction frame 253 moves with the end of the square cloth to the overlapping position and elastically extrudes the overlapping position. The double-sided adhesive tape on the bottom surface of the new square cloth end fully contacts and compacts the original square cloth. It is worth noting that when the suction accessory 25 moves upwards, the square cloth has started to move. The elastic extrusion of the expansion spring 255 on the suction frame 253 can ensure that the end of the new square cloth is tightly attached to the end of the original square cloth to be connected, thereby further enhancing the stability of the attachment.

[0052] As shown in Figure 4 , Figure 7 and Figure 8 , the overlapping assembly 2 comprises a cloth connecting assembly 211 for moving the end of the new square cloth. The cloth connecting assembly 211 comprises a motorized slide rail 212 sliding on the top of the upper roller frame 21. The vertical end of the fixed frame 23 is fixedly connected to the right end of the motorized slide rail 212. The middle part of the motorized slide rail 212 is provided with a second limiting groove 213. The limiting rod 214 is slidably connected to the inner side of the second limiting groove 213. The moving end of the first electric push rod 24 is provided with a rotating block 216. The first ear seat 215 is arranged on the side of the suction seat 251 corresponding to the rotating block 216. The first ear seat 215 is in a concave structure, and the opening of the first ear seat 215 is arranged to the left side. The first arc-shaped compression rod 217 is connected to the right side of the suction seat 251. One end of the first arc-shaped compression rod 217 away from the suction seat 251 is slidably connected to the top of the rotating block 216. The L-shaped limiting frame 218 is arranged at the front and rear ends of the U-shaped placing frame 291. The horizontal end of the L-shaped limiting frame 218 is provided with an L-shaped groove 219. The vertical end of the suction seat 251 corresponding to the L-shaped groove 219 is provided with a sliding rod.

[0053] It needs to be explained that when the new fabric needs to be overlapped on the installation roller 22, the electric slide rail 212 moves to the left side, the limiting rod 214 on the electric slide rail 212 can slide in the second limiting groove 213 to limit the moving range of the related components and play a guiding role, the slide rod on the adsorption seat 251 slides along the vertical part of the L-shaped groove 219 of the L-shaped limiting frame 218, when the slide rod reaches the corner of the L-shaped groove 219, the slide rod starts to move along the horizontal part of the L-shaped groove 219 because the electric slide rail 212 continues to drive to the left, in this process, the adsorption seat 251 rotates on the rotating block 216 by a certain angle, the first arc-shaped compression rod 217 is compressed, so that the adsorption seat 251 rotates to the appropriate angle and position (the adsorption structure below can face the fabric end on the installation roller 22), at this time, the adsorption structure on the adsorption seat 251 can be used to attract and fix one end of the fabric on the installation roller 22, the setting of the electric slide rail 212 realizes the automatic movement of the fabric connecting assembly 211, improves the automation degree of the whole fabric connecting action, reduces the tedious operation of manual participation in movement and positioning, improves the work efficiency and operation fluency.

[0054] After the fabric is fixed, the electric slide rail 212 is reset, at this time, when the slide rod reaches the vertical end of the L-shaped groove 219 and is separated from the L-shaped limiting frame 218, the spring potential energy of the first arc-shaped compression rod 217 is released, and the concave structure feature of the first ear seat 215 can make the rotating block 216 reset vertically on the first ear seat 215, the reset function of the electric slide rail 212 can quickly restore the fabric connecting assembly 211 to the initial position, so as to perform the overlapping operation on the new fabric.

[0055] As shown in Figure 9 , the two upper roller frames 21 are provided with telescopic sleeves 2191 on the opposite sides, the telescopic sleeves 2191 are in L-shaped structure, the vertical end of one of the telescopic sleeves 2191 is provided with a laser 2192, and the right side of the telescopic sleeve 2191 is provided with a lifting rod 2193 which is upwardly lifted along one side of the installation roller 22.

[0056] It needs to be explained that the step motor drives the installation roller 22 to rotate, so that the fabric is gradually released from the installation roller 22, and the two ends are lifted by the lifting rod 2193, when the fabric end reaches the height of the laser emitted by the laser 2192, the step motor stops rotating, so that the fabric is more easily adsorbed and fixed by the adsorption part 25.

[0057] As shown in FIG. 4 and Figure 9 , the left side of the telescopic sleeve 2191 is provided with a second ear seat 2194, one end of the lifting rod 2193 is rotatably connected inside the second ear seat 2194 through a rotating shaft, and the side wall of the telescopic sleeve 2191 is clamped and installed with a second arc-shaped compression rod 2195 which is slidably connected with the middle part of the lifting rod 2193.

[0058] It should be noted that when the overlap is completed and the installation roller 22 needs to be transferred (the robot takes out the unwinding roller 13 and installs the installation roller 22 at the position of the unwinding roller 13), the square cloth on the installation roller 22 will naturally have a downward movement tendency due to gravity and other factors. After the two sides of the square cloth contact the lifting rod 2193, as it continues to move downward, it will exert a downward pressure on the lifting rod 2193. Since one end of the lifting rod 2193 is connected by a rotating shaft inside the second ear seat 2194, when the lifting rod 2193 is subjected to downward pressure, it will rotate around the rotating shaft by a certain angle and move downward. The second arc-shaped compression rod 2195 is compressed. When the square cloth continues to move until it is separated from the lifting rod 2193, the second arc-shaped compression rod 2195 will push the lifting rod 2193 due to the release of its own elastic potential energy, causing the lifting rod 2193 to reverse the direction of its previous rotation and return to its initial position. The present application can automatically adapt to the movement of the square cloth in the transfer scenario and automatically reset, ensuring that when the next overlap operation is performed, the device can immediately be in an initial ready state without the need for manual resetting of the lifting rod 2193 and the like, improving the continuity and stability of the device operation.

[0059] As shown in FIGS. 4 and Figure 9 , the two upper roller frames 21 are connected to the opposite sides of the telescopic plate 2196. The end of the telescopic plate 2196 away from the roller frame 21 slides through the inside of the telescopic sleeve 2191, and the horizontal end of the telescopic sleeve 2191 is threadedly connected to the control rod 2197 for pressing the telescopic plate 2196.

[0060] It should be noted that the telescopic plate 2196 can slide inside the telescopic sleeve 2191. When it is necessary to adjust the length of the telescopic plate 2196 extending from the roller frame 21, the telescopic plate 2196 slides along the track of the telescopic sleeve 2191 to change its position. When the telescopic plate 2196 moves to the appropriate position, the control rod 2197 at the horizontal end of the telescopic sleeve 2191 is rotated to press the end of the control rod 2197 inwardly to press the telescopic plate 2196, and the telescopic plate 2196 is fixed at the current position by friction or pressing force. The length of the telescopic plate 2196 extending can be flexibly adjusted according to the material requirements of different sizes in actual production, thereby adapting to various production conditions and improving the versatility and flexibility of the device.

[0061] As shown in FIGS. Figure 4 , Figure 7 , and Figure 9 , the top surface of the U-shaped placement frame 291 is provided with a scale disc at the front and rear ends, the bottom of the adsorption seat 251 is provided with a position sensor at the front and rear ends, and the roller coating seat 12 is provided with a stroke electric push rod for driving the control seat 26 to move.

[0062] The position sensor can accurately detect the position information of the square cloth end in real time, and the position information is transmitted to the controller. The controller compares and calculates the actual position received with the set target position (i.e. the specified dial position). If the current position is inconsistent with the target position, the controller will control the action of the stroke electric push rod according to the size and direction of the deviation. The stroke electric push rod pushes the control seat 26 to move, thereby driving the square cloth end to move, so as to eliminate the deviation and finally make the square cloth end reach the specified dial position. The square cloth end is accurately moved to the specified position, so that the subsequent coating, processing and other operations can be more accurate and consistent, thereby improving the quality and performance of the product.

[0063] In addition, the application also provides a coating process used by the high-strength coated tape coating device, and the specific steps are as follows:

[0064] First, preparation: turn on the dehumidification unit, so that the dew point in the roll coating unit is less than or equal to -35°C, turn on the hot water circulation tank half an hour in advance, set the water tank temperature to 60°C and start the circulating water, and install the square cloth in roll form on the unwinding roller 13;
