Description

Technical Field

[0001] The invention belongs to the technical field of ultraviolet light curing, and in particular relates to an automatic folding device and a folding method for dry materials of an ultraviolet light curing hose. Background Art

[0002] UV curing technology is a new type of rapid curing technology. Its principle is to cure the coating or glue in a very short time through ultraviolet irradiation, so as to achieve the purpose of rapid production. This technology is widely used in printing, coating, glue and other industries. UV curing hose applies this technology to the production of hoses, so that the hoses can be cured in a very short time and improve production efficiency. Folding the dry material of UV curing hose is a key step in the production of UV curing hoses, that is, overlapping the two sides of the UV curing hose to the middle and forming a tubular structure, which is convenient for subsequent processes such as glue injection and stacking.

[0003] Chinese invention patent CN112622244A discloses a light-curing hose folding and sheathing device, comprising a folding groove, with material pouring rollers at both ends of the folding groove, and a plurality of lifting devices arranged at intervals below the folding groove, which work independently of each other; the folding device has low folding efficiency and poor folding effect.

[0004] Chinese invention patent CN117885329A discloses an automatic folding device for UV-curing hose dry materials and a method of using the same, comprising a base, with a discharge mechanism and a pulling mechanism respectively arranged on both sides of the top of the base, and a folding mechanism arranged on the top of the base between the discharge mechanism and the pulling mechanism; the folding device is difficult to fold and has low folding accuracy.

[0005] When the two sides of the UV-curing hose are actually folded, if there are impurities such as dust on the outer surface of the UV-curing hose, it will not only reduce the folding quality of the UV-curing hose, but also affect the subsequent pipeline repair quality of the UV-curing hose.

[0006] Furthermore, when wrinkles are present in the UV-curing hose, the above-mentioned prior arts lack the function of real-time detection and correction of wrinkles during the folding process of the UV-curing hose. If the UV-curing hose cannot be stretched in time, the subsequent folding smoothness will be directly affected.

[0007] At the same time, if the UV-curing hose tilts to one side during the conveying process, it will affect the accuracy of subsequent welding and eventually reduce the flatness of the folded UV-curing hose. Summary of the invention

[0052] The folding assembly 4 includes a folding plate 401, the inclination angle of the folding plate 401 rotates synchronously with the rotation of the fixed plate 312, a side groove 404 is provided at the lower side of the folding plate 401 close to the fixed plate 312, gas flows inside the side groove 404, a sleeve 405 is provided at the end of the side groove 404, and the gas flows into the sleeve 405 along the side groove 404, a plurality of exhaust holes 406 are evenly provided at the top of the sleeve 405, and the gas inside the sleeve 405 is discharged upward along the plurality of exhaust holes 406, and the sleeve 405 is sealed inside.

[0053] A plurality of connecting holes 402 are evenly arranged inside the folding plate 401, and a plurality of air pumps 403 are evenly arranged on the top of the folding plate 401. The bottom output end of the air pump 403 is connected to the top of the connecting hole 402. When the air pump 403 is started, gas is introduced into the connecting hole 402.

A transverse hole 419 is provided inside the steering frame 410, and a wedge-shaped push plate 414 is sealed and slidably connected inside the transverse hole 419. The wedge-shaped push plate 414 can move inside the transverse hole 419. A feed hole 411 is provided on the top of the steering frame 410, and the bottom of the feed hole 411 is connected to the inside of the transverse hole 419.

A follower plate 417 is provided on the other end of the connecting spring 416. The setting of the connecting spring 416 improves the elastic reset performance of the follower plate 417. The other end of the follower plate 417 matches the end of the wedge-shaped push plate 414. The wedge-shaped push plate 414 cooperates with the follower plate 417 to clamp and fix the end of the finished component 5. The outer surface of the follower plate 417 is sealed and slidably connected to the inner wall of the inner groove 415. The gas inside the transverse hole 419 will not enter the inner groove 415 and affect the movement of the follower plate 417. A plurality of distance sensors 418 are evenly provided on the inner bottom of the transverse hole 419. The distance sensor 418 is used to detect the distance value between the inner bottom of the transverse hole 419 and the end of the finished component 5.

[0056] The finished component 5 includes a protective film 501, which mainly plays a protective role. An outer film 502 is provided on the top of the protective film 501, a glass fiber 503 is provided on the top of the outer film 502, and an inner film 504 is provided on the top of the glass fiber 503. The structure of the outer film 502, the glass fiber 503 and the inner film 504 improves the stability and support of the subsequently formed UV-curing hose. The width of the protective film 501 is greater than the width of the outer film 502, and the bottom of the protective film 501 is transmission-connected to the outer surface of the rotating roller 207.

[0057] At the same time, the corresponding two fixed plates 312 have different inclination angles. Therefore, when the two sides of the finished component 5 are folded toward the middle to form a circular structure, the protective film 501 is on the outer surface of the circular structure, and in the actual folding process, the ends of the protective film 501 do not overlap, but the protective film 501 on one side is stacked on the protective film 501 on the other side. The corresponding fixed plate 312 located above the fold has a smaller inclination angle than the fixed plate 312 located below the fold. Then, the end of the protective film 501 on the top is welded. This arrangement avoids the subsequent use of the UV light-curing hose for non-excavation repair of the pipeline. The UV light-curing hose expands after being irradiated with UV light and provides expansion margin for the internal glass fiber 503, thereby avoiding the glass fiber 503 from increasing in volume and breaking during the expansion process, thereby reducing the quality of the pipeline repair.

[0058] When the two sides of the finished component 5 are actually folded, if there are dust and impurities on the outer surface of the finished component 5, it will not only reduce the quality of subsequent folding, but also affect the subsequent pipeline repair of the UV-curing hose; and when the finished component 5 has wrinkles, the prior art lacks the real-time detection and correction function of the finished component 5 during the folding process, and if the finished component 5 cannot be stretched in time, it will directly affect the subsequent folding flatness; and if the finished component 5 tilts to one side during the transmission process, it will affect the subsequent welding accuracy and ultimately reduce the flatness of the UV-curing hose formed by folding.

[0059] In actual use, the finished component 5 is pre-processed and produced, and the protective film 501, outer film 502, glass fiber 503 and inner film 504 inside the finished component 5 are stacked in sequence from bottom to top, and the width value of the protective film 501 is greater than the width values ​​of the outer film 502, the glass fiber 503 and the inner film 504. Then, the finished component 5 is placed above a plurality of rotating rollers 207, and the two sides of the finished component 5 are passed through the gap between the fixed plate 312 and the folding plate 401 in sequence. The end of the sliding sleeve 407 supports and tensions the outer surface of the inner film 504, and the protective film 501 continues to fold at the end of the steering frame 410 and extends into the inside of the transverse hole 419 along the feed hole 411. The distance value detected by the distance sensor 418 reaches the preset distance value.

[0060] Afterwards, the controller 106 controls the drive motor 203 to start and drives the rotating roller 207 at the end to rotate through the coupling 204. The rotating roller 207 drives multiple toothed belts 206 to rotate through the driving teeth 205. The toothed belts 206 are synchronously meshed with the multiple driving teeth 205 and drive multiple rotating rollers 207 to rotate synchronously. The rotating roller 207 and the bottom of the protective film 501 are squeezed and contacted with each other and use the friction force to drive the finished component 5 to be transported backward. At the same time, the two sides of the finished component 5 are continuously folded toward the middle under the action of multiple fixed plates 312 and folding plates 401 with different inclination angles. When the two side parts of the finished component 5 are stacked above the middle part and the two sides of the finished component 5 are also in an up and down stacking state, the end of the protective film 501 above the bent part and the outer surface of the protective film 501 below the bent part are welded with the help of a subsequent welding device, thereby completing the dry material folding process and forming the required UV-cured dry material.

[0061] At the same time, when the finished component 5 is being conveyed and folded, the controller 106 controls the multiple air pumps 403 to start and the output end to pass gas into the connection hole 402. The gas enters the side groove 404 along the connection hole 402 and enters the inside of the sleeve 405 along the side groove 404. At this time, since the sliding sleeve 407 is in the initial position and the matching hole 408 partially blocks the exhaust hole 406, the gas inside the sleeve 405 is discharged upward along the overlapping position of the exhaust hole 406 and the matching hole 408. The gas can be used to clean the inner wall of the finished component 5 by wind power to avoid impurities adhering to the inner wall when folding the two sides of the finished component 5, which reduces the subsequent folding quality. At the same time, the gas continues to go upward and along the guide hole 412. After entering the transverse hole 419, the gas acts on the side wall of the wedge-shaped push plate 414 and drives the wedge-shaped push plate 414 to stretch multiple return springs 413 and move toward the end of the follower plate 417. The end of the wedge-shaped push plate 414 is squeezed and contacted with the outer surface of the protective film 501, and the other end of the protective film 501 is squeezed and contacted with the side wall of the follower plate 417. The other end of the follower plate 417 is elastically supported by the connecting spring 416. At this time, the protective film 501 is at a stable height and the distance value detected by the distance sensor 418 reaches the preset distance value, thereby preventing the protective film 501 from shaking inside the feed hole 411 during the backward transmission process and reducing the subsequent folding and welding quality.

[0062] In addition, by making use of the feed hole 411 to perform a secondary folding on the end of the protective film 501, not only the accurate detection and calibration of the transmission folding of the finished component 5 is improved, but also the protective film 501 can perform internal and external wrapping protection on the inner outer film 502, glass fiber 503 and inner film 504 after the secondary folding of the turning frame 410, and correspondingly improve the welding protection performance of the subsequent protective film 501 during stacking and welding, so as to avoid the damage of the inner outer film 502, glass fiber 503 and inner film 504 by welding slag during welding of the protective film 501. At the same time, when the outer film 502, glass fiber 503 and inner film 504 are subsequently UV-cured in the internal and external wrapped state of the protective film 501, the outer film 502, glass fiber 503 and inner film 504 will only expand and move between the inner walls of the protective film 501, so as to avoid the outer film 502, glass fiber 503 and inner film 504 from rubbing and moving with the outer surface of the protective film 501 on the other side and causing damage to their own structure.

[0063] When the distance values ​​detected by the two groups of distance sensors 418 at the corresponding positions are both reduced and less than the preset distance values, it means that there are wrinkles in the middle position of the finished component 5, and the wrinkles synchronously stretch the two sides of the finished component 5 and cause the protective film 501 to move upward inside the feed hole 411. Therefore, the controller 106 controls multiple electric push rods 409 to start and the output ends to extend. The output ends of the electric push rods 409 drive the sliding sleeves 407 to move outward along the inside of the sleeve 405. At the same time, since the two sliding sleeves 407 move in opposite directions to each other, the thrust applied by the ends of the sliding sleeves 407 to the bend of the finished component 5 increases, and the wrinkles in the middle part of the finished component 5 are continuously smoothed under the thrust of the sliding sleeves 407 on both sides, thereby further improving the flatness of the finished component 5 and ensuring the folding quality of the finished component 5.

[0064] At the same time, when the sliding sleeve 407 moves outward along the sleeve 405, the multiple matching holes 408 are synchronously driven to move, the overlapping area of ​​the matching holes 408 and the exhaust holes 406 increases, and the amount of gas discharged upward along the multiple exhaust holes 406 inside the sleeve 405 increases. With the help of the change in the amount of gas discharged upward from the multiple exhaust holes 406, the wind cleaning effect of the gas on the inner wall of the finished component 5 is further improved, thereby ensuring the quality of the subsequent formation of the UV-curing hose by the finished component 5. At the same time, the gas action can also exert an upward force on the side wall of the finished component 5, and cooperate with the sliding sleeves 407 on both sides to move outward and exert a tensioning force on the inner wall of the finished component 5, thereby improving the synchronization and efficiency of the continuous upward movement and extension of the finished component 5 between the fixed plate 312 and the folding plate 401.

[0065] In addition, the gas discharged from the multiple exhaust holes 406 enters the interior of the transverse hole 419 along the guide hole 412, and with the help of the increased gas thrust, the wedge-shaped push plate 414 is driven to stretch the multiple return springs 413 to move closer to the follower plate 417 end, and the wedge-shaped push plate 414 drives the protective film 501 to squeeze the follower plate 417 on the other side to move along the inner groove 415, thereby applying a lateral thrust to the end of the protective film 501, so that the protective film 501 continuously restores the tensioned state under the action of the thrust. At the same time, when the wedge-shaped push plate 414 drives the end of the protective film 501 to move, the distance sensor 418 changes from detecting the distance value between the end of the protective film 501 to detecting the change value of the distance on the inclined surface of the wedge-shaped push plate 414, that is, when the wedge-shaped push plate 414 starts to drive the protective film 501 to move, the distance value detected by the distance sensor 418 decreases to the height value of the end of the wedge-shaped push plate 414.

[0066] As the wedge-shaped push plate 414 continues to move, the distance value detected by the distance sensor 418 continues to decrease. When the distance difference detected by the distance sensor 418 is equal to the distance reduction value of the end of the protective film 501 detected by the distance sensor 418, the controller 106 controls the electric push rod 409 to start and the output end is shortened to the initial value. The electric push rod 409 drives the sliding sleeve 407 to move in the opposite direction along the sleeve 405 to the initial value. The tensioning force applied by the sliding sleeve 407 to the inner wall of the protective film 501 is restored to the initial value. At the same time, the gas value discharged from the sleeve 405 along the multiple exhaust holes 406 along the internal gas is reduced, and the gas not only reduces the cleaning force on the inner wall of the finished component 5, but also reduces the cleaning force on the inner wall of the finished component 5. At the same time, the amount of gas entering the transverse hole 419 along the guide hole 412 is reduced, and the wedge-shaped push plate 414 and the follower plate 417 are driven to move in the opposite direction and return to their original positions under the elastic force of the reset spring 413 and the connecting spring 416. The wedge-shaped push plate 414 and the follower plate 417 drive the end of the protective film 501 to move in the opposite direction and return to their original positions. The protective film 501 extends downward along the feed hole 411. The distance value detected by the distance sensor 418 is continuously reduced. The above process is repeated for multiple times, and the finished component 5 is tensioned for multiple times, thereby ensuring the stability and flatness of the finished component 5 in transmission, and correspondingly improving the wind cleaning effect on the inner wall of the finished component 5.

[0067] When the distance values ​​detected by the two groups of distance sensors 418 at the corresponding positions change, and the distance value detected by one group of distance sensors 418 increases, while the distance value detected by the other group of distance sensors 418 decreases, it indicates that the finished component 5 is offset at this position, and the finished component 5 is tilted and offset to the side where the distance value detected by the distance sensor 418 increases. At this time, the controller 106 controls the electric push rod 409 on the side where the distance value detected by the distance sensor 418 decreases to start and the output end extends, and the electric push rod 409 on the side where the distance value detected by the other side of the distance sensor 418 increases to start and the output end extends. The outlet end is shortened, and the sliding sleeve 407 on the side where the distance value detected by the distance sensor 418 decreases moves outward, while the sliding sleeve 407 on the side where the distance value detected by the distance sensor 418 increases moves inward. Then, the tensioning force on the side where the distance value detected by the distance sensor 418 decreases is greater than that on the side where the distance value detected by the distance sensor 418 increases. Under the action of the common tensioning force of the two groups of sliding sleeves 407, the finished component 5 moves in the opposite direction to the side where the distance value detected by the distance sensor 418 decreases, thereby ensuring the stability and accuracy of the finished component 5 during the transmission process.

[0068] Similarly, when the distance value detected by the distance sensor 418 increases, the amount of gas discharged from the multiple exhaust holes 406 on one side decreases, and the gas enters the interior of the transverse hole 419 along the guide hole 412 and reduces the thrust exerted on the side wall of the wedge-shaped push plate 414, thereby reducing the clamping force of the wedge-shaped push plate 414 on one end of the protective film 501. When the distance value detected by the distance sensor 418 decreases, the clamping force of the wedge-shaped push plate 414 on the other end of the protective film 501 increases and drives the end of the protective film 501 to move toward that side, thereby cooperating with the movement of the sliding sleeve 407 to realize the correction of the position of the finished component 5, and continuously repeating the above process, thereby realizing the continuous push and calibration of the finished component 5 in the process of folding the finished component 5, thereby ensuring the synchronous center movement of the finished component 5.

[0069] The automatic folding equipment for UV-curing hose dry material is simple to operate and has precise control, meeting the needs of mass production of UV-curing hose dry material, and at the same time has high safety, good stability, strong adaptability and high synchronization; at the same time, when folding the finished component 5, the inner wall can be cleaned by wind, and the inner and outer wrapping of the end of the protective film 501 can be coordinated to improve the dust-free property and ensure the quality of subsequent non-excavation repair of the pipeline by the UV-curing hose; and when wrinkles occur inside the finished component 5, the two groups of sliding sleeves 407 and the wedge-shaped push plates 414 move synchronously to achieve further tensioning of both sides of the finished component 5, thereby achieving smooth and synchronous transmission and folding of the finished component 5; and when the finished component 5 deviates to one side, the two groups of sliding sleeves 407 and the wedge-shaped push plates 414 move in the opposite direction to push the finished component 5 to move in the opposite direction continuously, thereby achieving the concentricity of the transmission of the finished component 5 and the accuracy of folding.

[0070] Second embodiment

[0071] This embodiment discloses a folding method of an automatic folding device for UV-curable hose dry material, comprising the following steps:

[0072] S1. Place the finished component 5 above the rotating roller 207 for transmission. Both sides of the finished component 5 enter the inside of the horizontal hole 419 after being turned by the sliding sleeve 407 and the turning frame 410. The distance value detected by the distance sensor 418 reaches the set distance preset value.

[0073] S2. When the distance values ​​detected by the two sets of distance sensors 418 are both reduced, the sliding sleeve 407 moves outward along the sleeve 405, and the thrust applied by the end of the sliding sleeve 407 to the inner wall of the finished component 5 increases.

[0074] S3. When the sliding sleeve 407 moves outward, the amount of gas discharged from the exhaust hole 406 increases, the thrust on the side wall of the wedge-shaped push plate 414 increases, the wedge-shaped push plate 414 drives the end of the finished component 5 to move, and the distance difference detected by the distance sensor 418 is equal to the distance reduction value detected by the distance sensor 418 at the end of the finished component 5.

[0075] S4. When the distance value detected by one group of distance sensors 418 increases and the distance value detected by another group of distance sensors 418 decreases, the sliding sleeve 407 on the side where the distance value detected by the distance sensor 418 increases moves inward along the sleeve 405, the extrusion pressure on the inner wall of the finished component 5 decreases, and the thrust applied by the wedge-shaped push plate 414 to the end of the finished component 5 decreases.
