Description

Technical Field

[0001] This invention relates to the field of ultraviolet curing hose repair technology, and in particular to an automatic folding device for dry ultraviolet curing hoses and its usage method. Background Technology

[0002] Ultraviolet (UV) curing trenchless lining repair technology involves inserting a fiberglass flexible tube into the pipeline to be repaired, inflating it to ensure a tight fit with the existing pipeline, and then curing it with UV light to form a high-strength lining. This trenchless technology is widely used in pipeline repair projects due to its advantages such as fast construction speed, short construction period, high quality, tight fit between the lining and the pipeline, and minimal flow area loss.

[0003] To facilitate the insertion of fiberglass hoses into the pipes to be repaired using specialized equipment, the hoses need to be folded before being placed inside the pipes. However, the traditional method of folding hoses usually involves manual folding. Due to the varying sizes of the hoses and their smooth outer surfaces, slippage can easily occur during folding, reducing the folding effect. Furthermore, the folding operation is continuous and uninterrupted during the process of inserting the folded hoses into the pipes to be repaired using specialized equipment, which greatly increases the labor intensity of personnel and results in low repair efficiency.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic folding device for UV-curable tubing dry material and its usage method to solve the aforementioned technical defects. This invention, through a feeding mechanism and a guiding component working in conjunction with a folding mechanism, enables the positioning of tubing dry material of different widths both before and after folding, avoiding the problem of poor folding effect caused by the misalignment of one end of the folding plate with the middle of the tubing dry material. The feeding mechanism, working in conjunction with the guiding component, can both drive the tubing dry material roll to feed and fold, and avoid applying force to the folded tubing dry material at the folding position during the feeding process, preventing excessive creases and reducing the adhesion between the tubing dry material and the inner wall of the pipe during UV curing.

[0006] The objective of this invention can be achieved through the following technical solutions:

A through groove for the adjusting columns to pass through is provided through the inner wall of the through hole. Adjusting slots that are adapted to the corresponding adjusting columns are provided on both sides of the through groove at the bottom of the placement plate. A positioning sleeve that is slidably connected to the damping shaft is fixedly connected to the top of the placement plate.

[0012] Preferably, the material pulling mechanism includes a second fixed plate, a rotating roller, a transmission belt, a support plate, a second motor, a second guide roller, and a transmission roller. The top two sides of the base are symmetrically welded with second fixed plates. Two sets of rotating rollers are rotatably connected between the tops of the second fixed plates. The rotating rollers are connected via a transmission belt around their periphery. A support plate, slidably connected to the inner wall of the transmission belt, is fixedly connected between the two sets of rotating rollers on the second fixed plates. A second motor for driving the corresponding rotating roller is bolted to the outer wall of one side of the second fixed plate. A second guide roller and a transmission roller are rotatably connected below the rotating rollers on the second fixed plates. The second guide roller is slidably connected to the inner wall of the transmission belt, and the transmission roller is slidably connected to the outer wall of the transmission belt. A fixing component is provided on the outer wall of the second fixed plate.

[0013] Preferably, the fixing assembly includes a rotating plate, a fixed shaft, a vertical rod, a vertical plate, a slide groove, a mounting plate, and a counterweight.

[0014] Preferably, a support roller is rotatably connected to the bottom of the guide seat between the two guide rollers, and a guide roller is rotatably connected to the top of the fixed plate on the side close to the fixed plate.

[0015] A method for using an automatic folding device for UV-curable tubing dry materials includes the following steps:

[0016] Step 1: Placement and height adjustment of the hose dry material: According to the width of the hose dry material to be folded, adjust the height of the placement plate so that the distance between it and the folding plate is half the width of the hose dry material. Rotate the placement plate 90° so that its adjustment groove is directly above the corresponding height adjustment column and complete the engagement between the two. Place the hose dry material roll on the positioning sleeve on the placement plate.

[0017] Step 2: Folding and guiding the dry hose material: Insert the free end of the dry hose material between folding plate 1 and folding plate 2. Start motor 1 to drive the double-acting screw to rotate. Movable plate 1 and movable plate 2 move relative to each other. One side of folding plate 1 touches the middle of the dry hose material and folds the dry hose material under the action of folding plates 2 on both sides. At the same time as movable plate 1 and movable plate 2 move, the corresponding guide roller 1 moves synchronously to guide and clamp the folded dry hose material.

[0018] Step 3: Fixing and Continuous Folding of the Dried Hose Material: After the folded dried hose material is guided by the rollers and guide roller three, it is placed on top of the transmission belt. Two counterweights are placed at the center of the top of the folded dried hose material. Motor two is started to drive the rotating roller to rotate, which in turn drives the transmission belt to rotate. The transmission belt drives the transmission roller to rotate in the opposite direction. During the rotation of the transmission roller, the corresponding rotating plate, vertical plate, and vertical rod drive one side mounting plate to move synchronously with the direction of the transmission belt. The counterweights on the mounting plate press the folded dried hose material onto the transmission belt, and the hose material is pulled and folded in conjunction with the rotation of the transmission belt. Then, the counterweights move up and down while reversing to reset. During the reset process, the other side mounting plate repeats the above movements to complete the continuous pulling and folding.

[0019] The beneficial effects of this invention are as follows:

[0020] (1) The present invention provides an automatic folding device for UV curing tubing dry material. During the folding process of tubing dry material using folding plate one and folding plate two, the height of the rotating plate placed in the feeding mechanism is adjustable, so that the end of folding plate one can abut against the middle position of tubing dry material of different widths during the folding process, thereby achieving positioning feeding before folding; the guide component set on the movable plate can guide and clamp the two sides of the folded tubing dry material, thereby achieving positioning feeding after folding, further avoiding the problem of poor folding effect caused by the offset between the end of folding plate one and the middle of the tubing dry material; and the distance between the two guide seats can be adjusted by rotating the screw, thus being suitable for guiding and clamping tubing dry material of different widths after folding.

[0021] (2) In the automatic folding device for dry hose material of the present invention, when the dry hose material roll is pulled by the pulling mechanism to release the material, the transmission belt drives the transmission roller to rotate in the opposite direction. During the rotation of the transmission roller, the counterweight on one side of the mounting plate presses the middle part of the folded dry hose material onto the top of the transmission belt and moves in the same direction as it, so as to realize the pulling and folding effect of the dry hose material. At the same time, the counterweight on the other side of the mounting plate moves up and down while resetting in the opposite direction. Through the alternation and opposite movement of the two, the dry hose material is folded and the top and bottom sides are subjected to the same pulling force, so as to avoid the problem of restoring the original shape due to uneven force on the top and bottom sides during the pulling process.

[0022] (3) The automatic folding device for hose dry material of the present invention, through the detachable connection of the counterweight, can replace the corresponding counterweight according to the size of the hose dry material after folding according to different widths. With the guidance and clamping of the guide component, the counterweight is always located in the middle of the folded hose dry material during the pulling and folding process, thereby avoiding the application of force to the folding position during the pulling process, which would cause the crease to be too large and reduce the adhesion effect of the hose dry material to the inner wall of the pipe during the ultraviolet curing process.

[0023] In summary, by combining the feeding mechanism and the guiding component with the folding mechanism, the hose dry material of different widths can be positioned on both sides before and after folding during the folding process, avoiding the problem of poor folding effect caused by the misalignment of one end of the folding plate with the middle of the hose dry material. The feeding mechanism, in conjunction with the guiding component, can drive the hose dry material roll to feed and fold, and can also avoid applying force to the folded hose dry material at the folding position during the feeding process, which would cause excessive creases and reduce the adhesion of the hose dry material to the inner wall of the pipe during the UV curing process.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] The current method of manually folding dry hose materials results in high labor intensity and low folding efficiency. The following solutions can be implemented to address these issues:

[0043] Please see Figures 1-7 As shown, in this embodiment, an automatic folding device for UV-curable tubing dry material includes a base 1. A feeding mechanism 2 and a pulling mechanism 3 are respectively provided on the top two sides of the base 1. A folding mechanism 4 is provided on the top of the base 1 between the feeding mechanism 2 and the pulling mechanism 3.

[0044] The folding mechanism 4 includes a fixed plate 41, a slide bar 42, a movable plate 43, a movable plate 44, a folding plate 45, and a folding plate 46. Fixed plates 41 are symmetrically welded to both sides of the top of the base 1. Two sets of slide bars 42 are fixedly connected between the fixed plates 41. The slide bars 42 are used for sliding between the movable plates 43 and 44, thus facilitating the "feeding" of the hose dry material before folding and the folding of hose dry materials of different widths. The fixed plates 41 are connected to the two sets of slide bars 42. The movable plate 43 and movable plate 44 are connected. A folding plate 45 is fixedly connected to the middle of one side of the movable plate 43. A folding plate 46 is symmetrically fixedly connected to one side of the movable plate 44 and on both sides of the folding plate 45. Both the folding plate 45 and the folding plate 46 are right-angled trapezoidal structures, and the sloping side is located on one side of the feeding mechanism 2. This facilitates the transition effect of the dry material of the hose before it is fully folded, thereby avoiding the problem of stretching damage to the dry material of the hose. Both the movable plate 43 and the movable plate 44 are equipped with guide components 5.

[0045] A bidirectional lead screw 47 is rotatably connected between the fixed plate 41 and the movable plate 43 and the movable plate 44, and is threadedly connected to them. The bidirectional lead screw 47 enables the movable plate 43 and the movable plate 44 to move relative to each other or away from each other simultaneously. A motor 48 for driving the bidirectional lead screw 47 is bolted to the outer wall of one of the fixed plates 41. Several balls 49 are rolled and embedded on the top two sides of the folding plate 45 and the side away from the movable plate 43. The side of the folding plate 46 near the folding plate 45 and the side away from the movable plate 44 are also rolled and embedded. On one side, several ball bearings 410 are rolled and embedded. By rolling ball bearings 49 on folding plate 45 and 410 on folding plate 46, the wear of the hose material when folding plate 45 and folding plate 46 come into contact with each other during the relative movement of movable plate 43 and movable plate 44 can be reduced. On the other hand, the wear of the hose material during folding can be reduced and the efficiency of material pulling and folding can be improved, thereby improving the protection of the hose material during folding.

[0046] The feeding mechanism 2 includes a damping shaft 21, a placement rotating plate 22, an adjusting column 23, a through groove 24, an adjusting groove 25, and a positioning sleeve 26. The top of the base 1 is rotatably connected to the damping shaft 21, and the placement rotating plate 22 is provided on the damping shaft 21 to avoid the problem of feeding too fast during the folding process, which would cause the released hose dry material to accumulate in front of the folding mechanism 4 and thus affect the folding effect. Multiple adjusting columns 23 are fixedly connected at equal intervals along the vertical direction on both outer walls of the damping shaft 21. The placement rotating plate 22 has a through hole that is slidably connected to the damping shaft 21. The inner side wall of the through hole has a through groove 24 for the adjusting column 23 to pass through. The bottom of the placement rotating plate 22 is located on both sides of the through groove 24 and has an adjusting groove 25 that is adapted to the corresponding adjusting column 23.

[0047] By cooperating with the adjusting columns 23 of different heights and the adjusting groove 25, the distance between the placement plate 22 and the folding plate 45 can be adjusted. This allows the end of the folding plate 45 to abut against the middle position of the hose dry material of different widths during the folding process, thereby achieving the positioning and feeding effect before folding. The top of the placement plate 22 is fixedly connected to the positioning sleeve 26, which is slidably connected to the damping shaft 21. This can enhance the rotational stability of the placement plate 22 while avoiding the problem of the adjusting column 23 contacting the hose dry material and reducing the feeding effect.

[0048] The material pulling mechanism 3 includes a fixed plate 31, a rotating roller 32, a transmission belt 33, a support plate 34, a motor 35, a guide roller 36, and a transmission roller 37. Fixed plates 31 are symmetrically welded to both sides of the top of the base 1. Two sets of rotating rollers 32 are rotatably connected between the tops of the fixed plates 31. The rotating rollers 32 are connected via the transmission belt 33 around their periphery. The rotating rollers 32 and the transmission belt 33 achieve the pulling effect on the bottom of the folded hose dry material. A support plate 34, which is slidably connected to the inner wall of the transmission belt 33, is fixedly connected between the fixed plates 31 and the two sets of rotating rollers 32, raising the transmission belt 33 between the two rotating rollers. The support effect between the rollers 32 is that a motor 35 for driving the corresponding rotating roller 32 is bolted to the outer wall of the second fixed plate 31 on one side. The second fixed plate 31 is rotatably connected to the guide roller 36 and the transmission roller 37 respectively below the rotating roller 32. The guide roller 36 is rolled to the inner wall of the transmission belt 33, and the transmission roller 37 is rolled to the outer wall of the transmission belt 33. The guide roller 36 cooperates with the transmission roller 37 to realize that while the transmission belt 33 rotates, it drives the transmission roller 37 to move in the opposite direction, providing driving power for the fixed component 6. The fixed component 6 is provided on the outer wall of the second fixed plate 31.

[0049] The fixed assembly 6 includes a rotating plate 61, a fixed shaft 62, a vertical rod 63, a vertical plate 64, a slide groove 65, a mounting plate 66, and a counterweight 67. The rotating shafts at both ends of the transmission roller 37 pass through the corresponding fixed plate 31 and are fixedly connected to the rotating plate 61. The free ends of the two rotating plates 61 face opposite directions. By having the ends of the two rotating plates 61 face opposite directions, the corresponding mounting plate 66 is driven to move in the opposite direction during rotation. The free end of one side of the rotating plate 61 is fixedly connected to the fixed shaft 62. The top of the outer wall of the fixed plate 31 is fixedly connected to a slide rail 38, and a slider 39 is slidably connected to the slide rail 38. The vertical rod 63 is slidably connected to the slider 39. The slide rail 38 and the slider 39 cooperate to ensure that the vertical rod 63 moves horizontally under the drive of the mounting plate 66. The bottom end of the vertical rod 63 is fixedly connected to the vertical plate 64, and the vertical plate 64 has a slide groove 65 that is slidably connected to the corresponding fixed shaft 62.

[0050] When the vertical rod 63 moves to both sides of the slide rail 38, the top of the slide groove 65 contacts the fixed shaft 62, so that the rotating plate 61 is in a horizontal and upward movement and then downward movement (forming a semi-circular rotation effect), which drives the vertical rod 63 and the mounting plate 66 to move upward and downward, so that the mounting plate 66 does not affect the effect of the other mounting plate 66 pressing against the surface of the transmission belt 33. The top of the vertical rod 63 is fixedly connected to the mounting plate 66, and the bottom of the mounting plate 66 is bolted to the counterweight 67. The counterweight 67 on the mounting plate 66 presses the middle of the folded hose dry material onto the top of the transmission belt 33 and moves in the same direction as it, realizing the effect of pulling and folding the top of the hose dry material, avoiding the problem of easily returning to the original shape due to uneven force on the upper and lower sides during the pulling process.

[0051] Example 2

[0052] To address the issue of poor folding results caused by misalignment between one end of the folding plate and the middle of the dry material in the hose during the folding process, the following solutions can be implemented:

[0053] Please see Figure 1 , Figure 2 and Figure 4As shown, in this embodiment, the guide assembly 5 includes a connecting plate 51, a screw 52, ​​a guide seat 53, a guide roller 54, a telescopic rod 55, and a handwheel 56. The connecting plate 51 is fixedly connected to the side of the movable plate 43 and the movable plate 44 near the material pulling mechanism 3. The screw 52 is threadedly connected to the connecting plate 51. The guide seat 53 is rotatably connected to the end of the screw 52 away from the fixed plate 41. The guide roller 54 is symmetrically rotatably connected to both sides inside the guide seat 53. By the guide roller 54 set inside the guide seat 53, the two sides of the folded hose dry material can be guided and clamped, realizing the positioning and discharge after folding. This further avoids the problem of poor folding effect caused by the offset between the end of the folding plate 45 and the middle of the hose dry material. The distance between the two guide seats 53 can be adjusted by rotating the screw 52, ​​thus making it suitable for guiding and clamping hose dry materials of different widths after folding.

[0054] A telescopic rod 55 is fixedly connected between the connecting plate 51 and the corresponding guide seat 53 to prevent the guide seat 53 from rotating with the screw 52 when the screw 52 is rotated. A handwheel 56 is fixedly connected to the free end of the screw 52. With the guidance and clamping cooperation of the guide assembly 5, the corresponding counterweight 67 can be replaced according to the size of the folded hose dry material of different widths. This ensures that the counterweight 67 is always located in the middle of the folded hose dry material during the pulling and folding process, thereby avoiding the application of force to the folding position during the pulling process, which would cause excessive crease marks and reduce the adhesion effect of the hose dry material to the inner wall of the pipe during the UV curing process.

[0055] A support roller 57 is rotatably connected to the bottom of the guide seat 53 between the two guide rollers 54. A guide roller 310 is rotatably connected to the top of the fixed plate 31 near the fixed plate 41. Through the cooperation of the support roller 57 and the guide roller 310, the folded hose dry material can be guided during the conveying process. During the guiding and pulling process, the creases in the folded area can be strengthened, avoiding excessive strengthening of the crease marks and preventing the folded hose dry material from easily returning to its original shape.

[0056] Example 3

[0057] Please see Figures 1-8 As shown, a method for using an automatic folding device for UV-curable tubing dry materials includes the following steps:

[0058] Step 1: Placement and height adjustment of the hose dry material: According to the width of the hose dry material to be folded, adjust the height of the placement rotating plate 22 so that the distance between it and the folding plate 45 is half the width of the hose dry material. This ensures that the end of the folding plate 45 can abut against the middle position of hose dry materials of different widths during the folding process, thereby achieving positioning and feeding before folding; rotate the placement rotating plate 22 90° so that its adjustment groove 25 is directly above the corresponding height adjustment column 23 and complete the engagement between the two to fix the height of the placement rotating plate 22; and put the hose dry material roll onto the positioning sleeve 26 on the placement rotating plate 22.

[0059] Step Two: Folding and Guiding of the Hose Material: Insert the free end of the hose material between folding plate 1 (45) and folding plate 2 (46). Start motor 1 (48) to drive the double-acting screw 47 to rotate. Movable plate 1 (43) and movable plate 2 (44) move relative to each other. One side of folding plate 1 (45) abuts against the middle of the hose material, and under the action of folding plates 2 (46) on both sides, the hose material is folded. During the folding process, the rolling balls 1 (49) embedded on folding plate 1 (45) and 2 (410) embedded on folding plate 2 (46) fold together. On the one hand, it can reduce the wear of the folding plate 45 and folding plate 46 on the hose dry material during the relative movement of the movable plate 43 and the movable plate 44. On the other hand, it can reduce the wear of the folding plate 45 and folding plate 46 on the hose dry material during the folding process and improve the efficiency of material pulling and folding, thereby improving the protection effect of the hose dry material during the folding process. When the movable plate 43 and the movable plate 44 move, they drive the corresponding guide roller 54 to move synchronously to guide and clamp the folded hose dry material.

[0060] Step 3: Fixing and Continuous Folding of the Folded Hose Material: After the folded hose material is guided by roller 57 and guide roller 310, it is placed on top of the transmission belt 33. Two counterweights 67 are placed at the center of the top of the folded hose material. Motor 2 35 is started to drive the rotating roller 32 to rotate. The rotating roller 32 drives the transmission belt 33 to rotate. The transmission belt 33 drives the transmission roller 37 to rotate in the opposite direction. During the rotation of the transmission roller 37, the corresponding rotating plate 61, vertical plate 64 and vertical rod 63 drive the mounting plate 66 on one side to move synchronously with the direction of the transmission belt 33. The counterweights 67 on the mounting plate 66 press the folded hose material onto the transmission belt 33. The hose material is pulled and folded in conjunction with the rotation of the transmission belt 33. Then, the counterweights 67 move up and down while reversing to reset. During the reset process, the other mounting plate 66 repeats the above movements to complete the continuous pulling and folding.

[0061] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

6. A method of using an automatic folding device for UV-curable tubing dry materials, as described in claim 5, characterized in that... Includes the following steps: Step 1: Placement and height adjustment of the hose dry material: According to the width of the hose dry material to be folded, adjust the height of the placement plate (22) so that the distance between it and the folding plate (45) is half the width of the hose dry material. Rotate the placement plate (22) 90° so that its adjustment groove (25) is directly above the corresponding height adjustment column (23) and complete the engagement between the two. Place the hose dry material roll on the positioning sleeve (26) on the placement plate (22). Step 2: Folding and guiding the dry hose material: Pass the free end of the dry hose material through the folding plate 1 (45) and folding plate 2 (46). Start motor 1 (48) to drive the double-acting screw (47) to rotate. Movable plate 1 (43) and movable plate 2 (44) move relative to each other. One side of folding plate 1 (45) abuts against the middle of the dry hose material and folds the dry hose material under the action of folding plates 2 (46) on both sides. While moving movable plate 1 (43) and movable plate 2 (44) move, they drive the corresponding guide roller 1 (54) to move synchronously to guide and clamp the folded dry hose material. Step 3: Fixing and Continuing Folding of the Dried Hose Material: After the folded dried hose material is guided by the roller (57) and the guide roller three (310), it is placed on the top of the transmission belt (33). Two counterweights (67) are placed at the center of the top of the folded dried hose material. The motor two (35) is started to drive the rotating roller (32) to rotate. The rotating roller (32) drives the transmission belt (33) to rotate. The transmission belt (33) drives the transmission roller (37) to rotate in the opposite direction. During the rotation of the transmission roller (37), the corresponding rotating plate (61) passes through the roller. The vertical plate (64) and vertical rod (63) drive the mounting plate (66) on one side to move synchronously with the direction of the transmission belt (33). The counterweight (67) on the mounting plate (66) presses the folded hose dry material onto the transmission belt (33). The hose dry material is pulled and folded in coordination with the rotation of the transmission belt (33). Then, the counterweight (67) moves up and down while reversing to reset. During the reset process, the mounting plate (66) on the other side repeats the above movements of the mounting plate (66) to complete the continuous pulling and folding.
