[0002] The sheet material made of the treated glass fiber cloth, impregnated with the resin glue solution, and then heat treated to make the resin enter the B stage is called a prepreg. Currently, there are the following problems in the glass fiber cloth glue dipping processing:

[0003] For the feather edge glass fiber cloth, the excess glue will be brought out in the glue dipping process because of the two edges with the burr, and the edge burr needs to be cut off after pre-baking, which causes the waste of the resin glue solution, and also brings a large amount of resin dust to the burr cutting, which is not conducive to the product quality control.

[0004] For the edge sealed glass fiber cloth, that is, the glass fiber cloth with the edge burr cut off and coated with the glue layer for edge sealing, the edge will be coated with glue again after the glue dipping because of the edge with a layer of edge sealing glue layer. After pre-baking, the edge will be thicker than the middle because of the two layers of glue layer, and the winding will be uneven and even the edge will be seriously bulged and broken in the winding process.

[0005] The existing patent CN201020672009 discloses a scraper mechanism, which includes a mounting frame, a telescopic driving mechanism, a rotating part, and a scraper assembly with a blade.

Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application. ​

[0027] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship of two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] In various drawings of the present application, in order to facilitate illustration, some dimensions of structures or parts can be exaggerated relative to other structures or parts, therefore, only for illustrating the basic structure of the subject of the present application.

[0029] Please refer to Figures 1-3 The utility model provides a glue scraping assembly, including scraping unit 1, position detection unit 2, adjusting device 3, with adjusting device 3 is connected drive unit 4 and glue collecting unit 5. The glue scraping assembly is used for scraping the excess glue of both sides of the material M to be scraped, which can effectively solve the problems of difficult glue guiding, inconvenient adjustment and low automation in the prior art. The material M to be scraped includes but is not limited to glass fiber cloth.

[0030] The scraping unit 1 includes a first scraper 11 and a second scraper 12 arranged on opposite surfaces of the material M to be scraped. The first scraper 11 and the second scraper 12 are arranged on the front and back surfaces of the material M to be scraped, respectively. This arrangement can simultaneously process the excess glue on both surfaces of the material M to be scraped, improving the scraping efficiency.

[0031] The first scraper 11 and the second scraper 12 each include a scraping blade 13, a first connecting shaft 14 connected to the scraping blade 13, and an operating part 15 for driving the first connecting shaft 14 to rotate the scraping blade 13. By rotating the first connecting shaft 14 through the operating part 15, the scraping blade 13 can rotate 360° around the central axis of the first connecting shaft 14, making it easier to adjust to the appropriate scraping angle and facilitating the drainage of the glue.

[0032] The scraping blade 13 has an arc surface structure, which can better fit the surface of the material M to be scraped and facilitate the drainage of the glue, preventing the glue from dripping directly after being scraped and falling outside the glue collecting unit 5.

[0033] In one embodiment, the scraping blade 13 extends radially from the first connecting shaft 14, and the scraping blade 13 is curved along the circumference of the first connecting shaft 14. The scraping blades 13 of the first scraper 11 and the second scraper 12 are curved towards each other to scrape the front and back surfaces, respectively.

[0034] The operation part 15 is an adjusting hand wheel, which is convenient for the operator to manually adjust the angle of the scraper. By rotating the adjusting hand wheel, the scraping blade 13 can be rotated by any angle around the circumferential direction of the first connecting shaft 14, and the contact angle between the scraper and the fiberglass cloth can be accurately controlled, so as to obtain the best scraping effect.

[0035] The scraping blade 13 is connected with the first connecting shaft 14 by integral welding. The scraping blade 13 is connected with one end of the first connecting shaft 14, and the operation part 15 is connected with the other end of the first connecting shaft 14. This integrated structure improves the overall strength of the scraper and avoids the problem of easy loosening of the traditional detachable structure.

[0036] In an embodiment, the second scraper 12 is spaced apart from the first scraper 11 by a predetermined distance in the conveying direction of the material M to be scraped. Therefore, the second scraper 12 is arranged staggered with the first scraper 11 by a predetermined distance in the conveying direction of the material M to be scraped. This staggered arrangement can avoid the interference between the two scrapers and facilitate the separate collection of the materials.

[0037] In an embodiment, the predetermined distance is 1cm-20cm, preferably 5cm-10cm, which can ensure the smooth drainage of the materials and avoid mutual influence.

[0038] In an application scenario, the conveying direction is the up-down direction, and the material M to be scraped is conveyed from bottom to top, and the second scraper 12 is arranged spaced apart from the first scraper 11 in the height direction.

[0039] The position detection unit 2 is arranged above the scraping and guiding unit 1, and is used to detect the edge position of the material M to be scraped, and provide control basis for the driving unit 4.

[0040] In an embodiment, the position detection unit 2 includes an ultrasonic sensor for detecting the deviation of the edge of the material M to be scraped relative to the detection reference position. The detection principle of the ultrasonic sensor is to determine the position of the edge of the fiberglass cloth by emitting ultrasonic waves and receiving reflected waves. The detection center of the ultrasonic sensor is aligned with the edge of the fiberglass cloth, and when the edge of the fiberglass cloth deviates from the preset position, the sensor will output a corresponding deviation signal. Compared with the traditional photoelectric sensor, the ultrasonic sensor has the following advantages: not affected by the light transmission of the fiberglass cloth, more stable detection; not easily affected by environmental light; not sensitive to the color and surface state of the fiberglass cloth; has certain dustproof performance and is suitable for harsh working environment.

[0041] The preset position can be any set position, for example, the center position of the ultrasonic sensor. When the edge of the glass fiber cloth completely covers the center position of the ultrasonic sensor, no deviation signal is emitted; when the edge of the glass fiber cloth deviates from the center position of the ultrasonic sensor, the ultrasonic sensor outputs a corresponding deviation signal.

[0042] The adjusting device 3 is used to adjust the position of the scraping unit 1 and / or the position detection unit 2 relative to the material M to be scraped.

[0043] In an embodiment, the adjusting device 3 comprises a support 31, a sliding rail 32 arranged on the support 31, a sliding block 33 in sliding cooperation with the sliding rail 32, a second connecting shaft 34 connected with the sliding block 33, a fixing block 35 detachably fixed on the second connecting shaft 34, the first connecting shaft 14 is connected with the fixing block 35, the position detection unit 2 is connected with the second connecting shaft 34, and the sliding block 33 is connected with the driving unit 4.

[0044] In an embodiment, the fixing block 35 comprises a first channel fixed with the first connecting shaft 14 and a second channel fixed with the second connecting shaft 34, and the included angle between the axes of the first channel and the second channel is 85°-95°.

[0045] In an embodiment, the fixing block 35 further comprises a fixed channel in communication with the first channel, a damping pad 36 detachably connected in the fixed channel, and a fastener 37 detachably connected in the fixed channel, and the fastener 37 is located on the side of the damping pad 36 away from the first channel. The damping pad 36 abuts against the first connecting shaft 14, and is used to provide appropriate friction when adjusting the angle of the scraping blade 13, so that the adjusted scraping blade 13 can be stably maintained at the set position. This structure avoids the problem of repeatedly loosening and tightening the fixing bolt in the traditional technology, greatly improves the convenience and safety of adjustment, and also simplifies the operation of personnel and avoids the risk of falling caused by loosening the fastening screw.

[0046] It should be noted that the state of the assembly process described by the "damping pad 36 detachably connected in the fixed channel" can be that the damping pad 36 is detachably connected with the fixed channel, or that the damping pad 36 is fixed on the fastener 37.

[0047] In an embodiment, the damping pad 36 is a Teflon pad, and the fastener 37 is a goat horn screw fixed on the inner wall of the fixed channel by screw connection. On the one hand, the Teflon material has a suitable friction coefficient, which can provide a stable damping force to make the scraper adjustment flexible while maintaining the adjusted position; on the other hand, the replaceable design is adopted, which is convenient for replacing the damping pad 36 after wear, thereby prolonging the service life of the device. In actual application, the operator can manually adjust the angle of the scraper without loosening the fixing bolt, thereby avoiding the risk of parts falling off.

[0048] Specifically, the fixed channel has a threaded hole in the radial direction, the first connecting shaft 14 passes through the first channel, and a bolt with a damping pad 36 at the bottom is installed into the threaded hole, so that the damping pad 36 is fixed against the first connecting shaft 14 and the fixed block 35, thereby realizing the locking with adjustable tightness through the bolt, and ensuring that the scraper 13 can maintain the adjusted angle after adjustment.

[0049] In an embodiment, the second connecting shaft 34 includes a first branch shaft and a second branch shaft connected with the first branch shaft. One of the branch shafts is used to fix the fixed block 35, and the other branch shaft is connected with the sliding block 33 to realize position adjustment.

[0050] Specifically, one of the first branch shaft and the second branch shaft is consistent with the extension direction of the sliding channel 32, and the other is perpendicular to the extension direction of the sliding channel 32. The first branch shaft and the second branch shaft are perpendicular to each other and are welded, thereby providing stable support and reducing shaking during adjustment; having good rigidity, which can withstand the stress during scraping.

[0051] In addition, the first connecting shaft 14 is consistent with the extension direction of the sliding channel 32, thereby realizing the adjustment of the position of the scraper in the extension direction and the perpendicular direction of the sliding channel 32.

[0052] The driving unit 4 is communicatively connected with the position detection unit 2. The driving unit 4 controls the adjusting device 3 to adjust the position of the scraping unit 1 according to the signal of the position detection unit 2.

[0053] In an embodiment, the driving unit 4 preferably adopts an explosion-proof servo cylinder. The explosion-proof servo cylinder has an explosion-proof function and is suitable for use in flammable and explosive environments; has high precision in step control and can realize accurate positioning of less than 0.1 millimeter; has fast response speed and can timely adjust the position of the scraper; and has stable operation and small vibration, which is conducive to maintaining the stability of the scraping effect.

[0054] Specifically, when the position detecting unit 2 detects that the edge of the glass fabric completely covers the center position of the sensor by the ultrasonic sensor, the controller controls the extension or retraction of the explosion-proof servo cylinder in the driving unit 4 according to the accepted signal. When the ultrasonic sensor detects that the edge of the glass fabric is out of the center position of the sensor, the control system outputs a signal to drive the explosion-proof servo cylinder to extend, so that the sensor returns to the center position, thereby ensuring that the distance between the scraping unit and the edge of the glass fabric is constant.

[0055] The glue collecting unit 5 is used to collect the glue scraped by the scraping unit 1 and guide the glue to the outside of the metering roller, so as to prevent the glue from directly dropping on the metering roller. The glue collecting unit 5 includes but is not limited to a glue receiving box, and the specific structure and shape thereof are not limited.

[0056] In an embodiment, the glue collecting unit 5 includes a glue receiving slope 51 and a discharge port 52 arranged at the lowest part of the glue receiving slope 51. The discharge port 52 is arranged at the lowest part of the glue receiving slope 51 and is used to guide the collected glue out, thereby facilitating subsequent recycling.

[0057] In a specific embodiment, the included angle between the glue receiving slope 51 and the horizontal plane is 30°-60°. Specifically, when the inclination angle of the glue receiving slope 51 is less than 30 degrees, the flow speed of the glue on the slope is slow, and the glue is easy to accumulate on the slope; when the inclination angle is greater than 60 degrees, the glue is easy to splash due to the action of gravity. Therefore, by setting the inclination angle in the range of 30°-60°, the glue can flow smoothly under the action of gravity, which not only ensures the smooth discharge of the glue, but also avoids the splashing phenomenon.

[0058] As shown in Figure 1 The utility model also provides a glue scraping device 100, including a pair of the glue scraping assembly.

[0059] A pair of glue scraping assemblies are arranged along the width direction of the material M to be scraped, and the width direction is perpendicular to the conveying direction of the material M to be scraped. This symmetrical arrangement can simultaneously process the excess glue on both sides of the glass fabric, ensure the force balance on both sides of the glass fabric, avoid uneven tension, improve the versatility of the equipment, and be suitable for glass fabrics with different widths and convenient for unified management and maintenance by the operator.

[0060] In actual application, the working process of the device mainly includes the following steps.

[0061] Before starting, the initial positions of the scrapers in the glue scraping assemblies on both sides are adjusted according to the actual width of the glass fabric; and the initial angle of the scraper is set by adjusting the hand wheel.

[0062] After starting the device, the ultrasonic sensor monitors the edge position of the glass fabric in real time; when the edge position deviation is detected, the driving unit 4 automatically adjusts the position of the scraper; the scraped glue flows along the curved scraper 13 to the glue collecting unit 5; the collected glue is discharged through the discharge port 52.

[0063] Specifically, first, the position detection unit 2 is started, so that the edge of the glass fabric is located at the center of the ultrasonic sensor, and then the position of the scraper assembly is adjusted according to the position of the glass fabric. By manually rotating the operation part 15, the angle of the scraper 13 is adjusted, and by moving the fixed block 35 on the second connecting shaft 34, the distance of the scraper 13 relative to the glass fabric can be adjusted. Finally, the scraping unit 1 keeps the width of the glue constant, and the scraped glue can be introduced into the glue collecting unit 5, so that it can be used normally.

[0064] If the ultrasonic sensor detects that the edge of the glass fabric deviates from the center position of the sensor, the control system outputs a signal to drive the explosion-proof servo cylinder to extend, so that the ultrasonic sensor returns to the center position. When the ultrasonic sensor detects that the edge of the glass fabric is just at the center position of the sensor, no signal is output.

[0065] In summary, the first scraper 11 and the second scraper 12 cooperate to simultaneously process the glue on the front and back surfaces of the material to be scraped M; and the cooperation of the arc-shaped scraper 13 and the operation part 15 realizes the arbitrary adjustment of the position of the scraper 13, and the scraping effect is good. And through the cooperation of the position detection unit 2, the adjusting device 3 and the driving unit 4, the automatic adjustment of the scraping unit 1 and / or the position detection unit 2 is realized, and the manual intervention is reduced.

[0066] It should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0067] The series of detailed descriptions listed above are only specific descriptions of the feasible embodiments of the utility model, and they are not used to limit the protection scope of the utility model, and any equivalent embodiments or changes made without departing from the spirit of the utility model art should be included in the protection scope of the utility model.
