Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of superconducting tape processing, and particularly relates to an epoxy resin smearing device for high-temperature superconducting tape. BACKGROUND

[0002] Epoxy resin smearing for high-temperature superconducting tape is a common superconducting material processing technology, which is mainly used to improve the mechanical properties, chemical stability and electrical insulation of high-temperature superconducting tape. As a common composite matrix, epoxy resin has good adhesion, heat resistance and corrosion resistance, which can effectively protect the superconducting tape from the influence of the external environment and ensure its stable operation under high temperature and high current conditions. In the smearing process, the epoxy resin is first uniformly smeared on the surface of the superconducting tape to ensure that there is no gap, and then it is solidified by heating to form a close combination with the tape.

[0003] The conventional resin smearing device mainly consists of smearing and solidifying parts, wherein the smearing device sprays the surface of the tape, and after the spraying is completed, the solidifying treatment is carried out. However, such smearing device has a simple structure, and there may be small dust and impurities on the surface of the tape during smearing, which can cause bubbles on the surface after smearing, affecting the quality of the coating.

[0004] At the same time, the conventional smearing device adopts an up-down simultaneous spraying mode for smearing. Although this smearing mode can improve the efficiency to a certain extent, the smearing at the bottom end is not uniform due to the influence of gravity, which can easily cause the dripping of the coating, seriously affecting the quality of the coating, and the thickness of the coating is difficult to accurately control, further affecting the smearing quality. SUMMARY

[0005] The purpose of the present application is to provide an epoxy resin smearing device for high-temperature superconducting tape to solve the problems raised in the background art.

[0006] In order to achieve the above-mentioned purpose, the present application provides the following technical scheme: an epoxy resin smearing device for high-temperature superconducting tape, comprising a pretreatment assembly, a first smearing box is fixedly connected to the right end of the pretreatment assembly, a second smearing box is installed on the right side of the upper part of the pretreatment assembly, a rear end treatment assembly is installed on the left side of the upper part of the pretreatment assembly, the second smearing box and the rear end treatment assembly are fixedly connected, a reversing box is fixedly connected to the right side of the first smearing box, the reversing box and the second smearing box are connected, a first reversing roller is movably installed on the position close to the bottom end in the inner cavity of the reversing box, a second reversing roller is movably installed on the position close to the top end in the inner cavity of the reversing box, and the rear end treatment assembly is connected with an external air pump. The pretreatment assembly is used to actively clean the high-temperature superconducting tape, the first coating box and the second coating box are used to coat the two sides of the high-temperature superconducting tape respectively, the reversing box is used to change the coating surface of the high-temperature superconducting tape on the upper side, and the back-end treatment assembly is used to control the coating degree of the high-temperature superconducting tape and complete the curing; When the high-temperature superconducting tape is fed, it passes through the pretreatment assembly and the first coating box in sequence, and after completing the reversal inside the reversing box, it passes through the second coating box and the back-end processing assembly in sequence before being discharged.

[0007] When coating the high-temperature superconducting tape, the coating end needs to be inserted into the device and finally discharged from the discharge end of the back-end processing component. At the same time, an external traction device is used to pull the high-temperature superconducting tape to ensure its continuous movement in the device and complete the preparation before the coating process.

[0008] As a further technical solution of the present invention, resin spray heads are installed at the top of the inner cavities of the first coating box and the second coating box, and feeding pipes are installed at the input ends of the resin spray heads. The end of the feeding pipe away from the resin spray head is connected to an external resin feeding device.

[0009] The pretreated strip is pulled by the external traction equipment and then enters the interior of the first coating box. At this time, the resin spray head located inside the first coating box can be opened, and the paint then enters the resin spray head inside the first coating box through the feed pipe, and is sprayed on the upper surface of the strip. After spraying, the strip is guided by the first reversing roller and the second reversing roller in turn. At this time, the original lower surface of the strip is located at the top, completing the reversing process of the strip. The strip after reversing then enters the interior of the second coating box, and is sprayed on the surface again through the resin spray head, completing the spraying process of each side of the strip.

[0010] By respectively providing a first coating box and a second coating box, and staggering the first coating box and the second coating box, and performing a reversing operation through the first reversing roller and the second reversing roller, the device can spray a single side of the strip respectively, and at the same time, when spraying the two single sides, a top-down spraying method is adopted to reduce the dripping of the paint, which is in line with intuition and avoids the problem of uneven spraying when double-sided spraying is performed at the same time. At the same time, it can avoid taking out the strip before spraying the other side, taking into account both the spraying quality and the spraying efficiency.

[0011] As a further technical solution of the present invention, the pretreatment component includes a pretreatment box, and openings for high-temperature superconducting tape are opened on the left and right sides of the pretreatment box. Annular grooves are opened on the front and back sides of the pretreatment box, and roller brushes are symmetrically installed inside the upper and lower annular grooves on the left side, and cleaning nozzles are symmetrically installed inside the upper and lower annular grooves on the right side. The two groups of symmetrically arranged roller brushes and cleaning nozzles are displaced up and down relative to the annular grooves.

[0012] As a further technical scheme of the present application, the front and rear sides of the pre-treatment box are provided with sealing boxes, an upper linkage plate located inside the sealing box is fixedly sleeved between the upper brush and the cleaning nozzle, a lower linkage plate located inside the sealing box is fixedly sleeved between the lower brush and the cleaning nozzle, and an electric push rod is installed between the upper linkage plate and the lower linkage plate.

[0013] As a further technical scheme of the present application, the electric push rod is used to adjust the distance between the upper linkage plate and the lower linkage plate, the distance between the upper and lower brushes and the upper and lower cleaning nozzles is synchronously adjusted, and the upper linkage plate and the lower linkage plate are connected with the rear-end treatment assembly.

[0014] As a further technical scheme of the present application, the two cleaning nozzles are fixedly connected with gas supply pipes at the ends away from each other, the two gas supply pipes are fixedly connected with each other without a three-way valve, and the other end of the three-way valve is connected with an external air pump.

[0015] When the strip is sprayed, the end to be processed of the strip can be inserted into the opening of the pre-treatment box, the electric push rod is turned on, and the upper and lower ends thereof are synchronously shortened, at this time, the upper linkage plate and the lower linkage plate are relatively close, and drive the upper and lower brushes to be relatively close, until the outer side of the brush contacts the surface of the strip, with the displacement of the strip, the brush rolls and actively cleans the surface of the strip, and the external air pump can be synchronously turned on, high-pressure air enters the upper and lower gas supply pipes through the three-way valve, and enters the two cleaning nozzles, to blow air on the surface of the strip at the same time, to complete the pre-treatment process.

[0016] Through the use of the pre-treatment assembly and the traction process of the strip, the strip can be subjected to a pre-treatment process before being sprayed, to remove dust and impurities on the surface of the strip, to avoid causing adverse phenomena such as air bubbles in the subsequent spraying process, to improve the service life of the coating, and to significantly improve the overall spraying quality of the strip.

[0017] As a further technical scheme of the present application, the rear-end treatment assembly comprises a recovery box, the right end of the recovery box is fixedly connected with the left end of the second coating box, and the upper and lower ends of the left side of the recovery box are provided with electric heat curing devices, the output ends of the upper and lower electric heat curing devices are connected with the recovery box and cure the upper and lower ends of the high-temperature superconducting strip.

Lower linkage frames are installed on the front and rear sides of the lower scraper, and the end of the lower linkage frame away from the lower scraper is connected to the lower linkage plate.

[0020] When the entire surface of the strip is sprayed, the strip enters the interior of the recycling box. At the same time, when the upper linkage plate and the lower linkage plate are relatively close, that is, when the upper linkage plate moves downward, the upper scraper is driven to move downward through the upper linkage frame, and when the lower linkage plate moves upward, it can drive the lower linkage frame to move upward. At this time, the lower scraper moves upward, and the distance between the upper scraper and the lower scraper decreases until both the upper scraper and the lower scraper are in contact with the surface of the strip. As the strip moves, the surface of the strip is scraped off to complete the thickness control of its surface coating. After the thickness control is completed, the strip continues to move and enters between the two electric thermal curing devices, and the curing process of the strip surface coating is completed by the electric thermal curing devices.

[0021] Through the coordination between the back-end processing components and the pre-processing components, after the device completes the limitation of the strip surface, the position adjustment process of the upper scraper and the lower scraper can be completed synchronously, and the coating thickness can be accurately controlled by the upper scraper and the lower scraper. The curing process is quickly carried out through the electric thermal curing device, which significantly improves the coating quality.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention utilizes the pretreatment components and the strip pulling process.

At the same time, when spraying the two single sides, a top-down spraying method is adopted to reduce the dripping of the paint, which is in line with intuition and avoids the problem of uneven spraying when spraying on both sides at the same time. At the same time, it can avoid taking out the strip before spraying the other side, taking into account both the spraying quality and the spraying efficiency.

[0029] When coating high-temperature superconducting tape, coating end needs to be inserted into the device, and finally be guided out from the discharge end of rear end processing component 9, while using external traction device to pull high-temperature superconducting tape, to ensure its continuous movement in the device, to complete the preparation before coating processing.

[0030] As shown in the present application, Figure 1 And as shown in 2 and Figure 4 And Figure 9 As shown in the present application, the top end of the inner cavity of first coating box 2 and second coating box 3 is respectively provided with resin spray head 7, the input end of resin spray head 7 is respectively provided with feeding pipe 8, and the end of feeding pipe 8 away from resin spray head 7 is connected with external resin feeding device.

[0031] Embodiment: after pretreatment, the tape is pulled by external traction equipment, and then enters the inside of first coating box 2, at this time, resin spray head 7 in the inside of first coating box 2 can be opened, at this time, coating is guided into resin spray head 7 in the inside of first coating box 2 through feeding pipe 8, and the upper surface of the tape is sprayed, after spraying, the tape is guided by first reversing roller 5 and second reversing roller 6 in sequence, at this time, the lower surface of the tape is above, the reversing process of the tape is completed, and the tape after reversing enters the inside of second coating box 3, and the surface of the tape is sprayed again by resin spray head 7, to complete the spraying process of single side of the tape.

[0032] By respectively setting the first coating box 2 and the second coating box 3, and staggered arrangement of the first coating box 2 and the second coating box 3, and through the reversing operation of the first reversing roller 5 and the second reversing roller 6, the device can respectively spray the single side of the strip, and at the same time of spraying the two single sides, the spraying is in the top-down manner, which reduces the dropping of the paint, conforms to the intuition, avoids the problem of uneven spraying when spraying the two sides at the same time, and at the same time can avoid taking out the strip to spray the other side, and takes into account the spraying quality and spraying efficiency.

[0033] As shown in Figure 4 and Figure 5 and Figure 7 and Figure 8 As shown in the drawings, the pretreatment assembly 1 comprises a pretreatment box 101, and openings for the high-temperature superconducting strip are formed on the left and right sides of the pretreatment box 101. Annular grooves are formed on the front and rear sides of the pretreatment box 101, and symmetrical rolling brushes 102 are installed inside the upper and lower annular grooves on the left side. Symmetrical cleaning nozzles 103 are installed inside the upper and lower annular grooves on the right side. The two groups of symmetrical rolling brushes 102 and cleaning nozzles 103 are displaced up and down relative to the annular grooves. Sealing boxes 109 are installed on the front and rear sides of the pretreatment box 101. An upper linkage plate 104 located inside the sealing box 109 is fixedly sleeved between the upper rolling brush 102 and the cleaning nozzle 103. A lower linkage plate 105 located inside the sealing box 109 is fixedly sleeved between the lower rolling brush 102 and the cleaning nozzle 103. An electric push rod 106 is installed between the upper linkage plate 104 and the lower linkage plate 105. The electric push rod 106 is used to adjust the distance between the upper linkage plate 104 and the lower linkage plate 105. The distance between the upper and lower rolling brushes 102 and the upper and lower cleaning nozzles 103 is adjusted synchronously. The upper linkage plate 104 and the lower linkage plate 105 are connected between the pretreatment assembly 9. The two cleaning nozzles 103 are fixedly connected with gas pipes 107 at the ends away from each other. The two gas pipes 107 are fixedly connected with a three-way valve 108. The other end of the three-way valve 108 is connected with an external air pump.

[0034] In the embodiment, when the strip is sprayed, the end to be processed of the strip is inserted into the opening of the pretreatment box 101, the electric push rod 106 is turned on, and the upper and lower ends are synchronously shortened. At this time, the upper linkage plate 104 and the lower linkage plate 105 are relatively close, and the upper and lower rolling brushes 102 are driven to be close to each other. Until the outer side of the rolling brush 102 is in contact with the surface of the strip, with the displacement of the strip, the rolling brush 102 rolls and actively cleans the surface of the strip. At the same time, the external air pump is turned on, high-pressure air enters the upper and lower gas pipes 107 through the three-way valve 108, and enters the two cleaning nozzles 103, and blows air up and down on the surface of the strip, completing the pretreatment process.

[0036] like Figure 4 and Figure 5 as well as Figure 6 As shown, the back-end processing component 9 includes a recycling box 901, the right end of the recycling box 901 is fixedly connected to the left end of the second coating box 3, and the upper and lower ends of the left side of the recycling box 901 are equipped with electric thermal curing devices 902. The output ends of the upper and lower electric thermal curing devices 902 are connected to the recycling box 901 and cure the upper and lower ends of the high-temperature superconducting tape. An annular groove is provided on the front and rear sides of the recycling box 901 near the right side. An upper scraper 903 is movably installed inside the upper annular groove, and a lower scraper 904 is movably installed inside the lower annular groove. The upper scraper 903 and the lower scraper 904 are symmetrically arranged up and down and move up and down relative to the annular groove. An upper linkage frame 905 is installed on the front and rear sides of the upper scraper 903, and the end of the upper linkage frame 905 away from the upper scraper 903 is connected to the upper linkage plate 104. A lower linkage frame 906 is installed on the front and rear sides of the lower scraper 904, and the end of the lower linkage frame 906 away from the lower scraper 904 is connected to the lower linkage plate 105.

[0037] Embodiment: After all the spraying on the surface of the strip is completed, the strip enters the interior of the recycling box 901. At the same time, when the upper linkage plate 104 and the lower linkage plate 105 are relatively close, that is, when the upper linkage plate 104 moves downward, the upper scraper 903 is driven to move downward through the upper linkage frame 905, and when the lower linkage plate 105 moves upward, it can drive the lower linkage frame 906 to move upward. At this time, the lower scraper 904 moves upward, and the distance between the upper scraper 903 and the lower scraper 904 decreases until the upper scraper 903 and the lower scraper 904 are in contact with the surface of the strip. As the strip moves, the surface of the strip is scraped off to complete the thickness control of its surface coating. After the thickness control is completed, the strip continues to move and enters between the two electric thermal curing devices 902, and the curing process of the strip surface coating is completed by the electric thermal curing device 902.

[0038] Through the coordination between the back-end processing component 9 and the pre-processing component 1, after the device completes the limitation of the strip surface, the position adjustment process of the upper scraper 903 and the lower scraper 904 can be completed synchronously, and the coating thickness can be precisely controlled by the upper scraper 903 and the lower scraper 904, and the curing process can be quickly carried out by the electric thermal curing device 902, which significantly improves the coating quality.

[0039] Working principle and usage process: In the process of coating the high-temperature superconducting tape, the coating end is inserted into the device and finally guided out from the discharge end of the rear end processing assembly 9, while the high-temperature superconducting tape is pulled by the external traction device to ensure its continuous movement in the device and complete the preparation before coating processing; In the process of spraying the tape, the tape to be processed can be inserted into the opening of the pretreatment box 101, and the electric push rod 106 is opened, and the upper and lower ends are controlled to be shortened synchronously. At this time, the upper linkage plate 104 and the lower linkage plate 105 are relatively close, and drive the upper and lower roller brushes 102 to be relatively close, until the outer side of the roller brush 102 contacts the surface of the tape. With the displacement of the tape, the roller brush 102 rolls and actively cleans the surface of the tape. The external air pump can be opened synchronously, and high-pressure air enters the upper and lower gas pipes 107 through the three-way valve 108, and enters the two cleaning nozzles 103 to blow air on the surface of the tape simultaneously, completing the pretreatment process. After pretreatment, the tape is guided into the inside of the first coating box 2 by the external traction equipment. At this time, the resin spray head 7 in the first coating box 2 can be opened. At this time, the coating enters the resin spray head 7 in the inside of the first coating box 2 through the inlet pipe 8, and sprays the upper surface of the tape. After spraying, the tape is guided by the first reversing roller 5 and the second reversing roller 6. At this time, the lower surface of the tape is above, completing the reversing process of the tape. The reversed tape enters the inside of the second coating box 3 and is sprayed on the surface again by the resin spray head 7, completing the spraying process on one side of the tape. When the spraying of the surface of the tape is completed, the tape enters the inside of the recovery box 901. When the upper linkage plate 104 and the lower linkage plate 105 are relatively close, that is, the upper linkage plate 104 is displaced downward, the upper scraper 903 is displaced downward by the upper linkage frame 905. When the lower linkage plate 105 is displaced upward, the lower linkage frame 906 is displaced upward. At this time, the lower scraper 904 is displaced upward, and the distance between the upper scraper 903 and the lower scraper 904 is reduced until the upper scraper 903 and the lower scraper 904 contact the surface of the tape. With the displacement of the tape, the surface of the tape is scraped to control the thickness of the surface coating. After thickness control, the tape continues to displace and enters between the two electric heat curing devices 902 to complete the curing process of the surface coating of the tape.
