Description

TECHNICAL FIELD

[0001] The utility model relates to the field of CIPP technology, and particularly relates to a CIPP hose manufacturing auxiliary shaping apparatus. BACKGROUND

[0002] CIPP hose manufacturing refers to a repair method in which a resin-impregnated hose is placed into an original pipeline through overturning or pulling, and after curing, a pipeline lining is formed. During CIPP hose manufacturing, production equipment adds a mixed resin system into a dry pipe, and through vacuum defoaming, slurry guiding, and roller pressing, the resin system is ensured to fully diffuse and infiltrate in the dry pipe fibers, forming a unified whole, which is then packaged to produce a CIPP repair hose. During the hose rolling forming stage, the slurry fills the front end of the dry pipe, and then the rolling equipment is started. Under the action of the rolling shaft driven by the equipment, the slurry-filled front end of the dry pipe enters the pipeline pressing module. The slurry amount in the dry pipe segment to be pressed is dynamically controlled according to the slurry filling speed, and the pre-embedded small pipeline end is always kept at the entrance end of the pressing module. When the rolling reaches the tail of the dry pipe, the small pipeline is extracted, and sealing treatment is performed synchronously, finally forming a certain thickness of the shaped hose. The existing technology has the following problems:

[0003] Chinese patent document CN216733080U discloses a CIPP hose manufacturing device. The device includes a dry pipe, a vacuum machine, a filling machine, a conveying device, and a rolling device. The dry pipe is located on the conveying device and is transported by the conveying device. One or more inner pipelines are pre-embedded in the dry pipe, and the inner pipeline end is perforated and has continuous pores on the pipe wall. The rolling device rolls from the front end of the dry pipe to the tail of the dry pipe. The utility model utilizes the channel formed by the pre-embedded pipeline end and pores to extract vacuum from the dry pipe, which can avoid air leakage and soft hose quality problems caused by insufficient repair after multiple perforations. Reusing the pre-embedded pipeline to fill the material can avoid the mixing of air when re-perforating or using the air extraction hole to fill the material, which can cause excessive air bubbles in the soft hose after curing and forming, affecting the pipeline repair quality. The pre-embedded pipeline filling and soft hose rolling are performed synchronously, the slurry amount is dynamically controlled by adjusting the grouting speed, and finally a shaped hose with uniform slurry is formed.

[0004] In the rolling forming stage of the CIPP hose manufacturing in the above-mentioned document, a rolling shaft is needed to assist in shaping. When the rolling shaft and the conveying belt are used to extrude the soft hose gradually filled with slurry, the rolling shaft lacks left and right positioning measures for the soft hose, which may cause the soft hose to deviate left and right when being rolled and moved, and cannot ensure stable rolling of the soft hose. Moreover, the height of the rolling shaft in the above-mentioned document cannot be adjusted, which makes it difficult to adapt to the rolling requirements of soft hoses of different models and thicknesses, and the applicability is poor.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2 As shown, this utility model provides an auxiliary shaping device for CIPP hose manufacturing, including an auxiliary shaping mechanism 1. A fiberglass tube 5 is arranged below the auxiliary shaping mechanism 1, and a conveying mechanism 2 is arranged below the fiberglass tube 5. A discharge mechanism 4 is arranged behind the conveying mechanism 2, and a filling machine 3 is arranged in front of the conveying mechanism 2. The auxiliary shaping mechanism 1 includes a gantry frame 11, with extension rods 12 fixedly installed on the front of two vertical sections of the gantry frame 11. Positioning horizontal plates 13 are fixedly installed at the front ends of the two extension rods 12, and clamping drive grooves 1 are formed at the bottom of the positioning horizontal plates 13. 4. A positive and negative threaded rod 15 is movably installed on the right side of the inner wall of the clamping drive groove 14. The left end of the positive and negative threaded rod 15 extends through to the left side of the positioning horizontal plate 13 and is fixedly installed with a knob 16. The left and right sides of the outer wall of the positive and negative threaded rod 15 are respectively provided with threaded walls with opposite threads, and the outer walls of the two threaded walls are threaded with hanging plates 17. The front and rear sides of the two hanging plates 17 overlap with the front and rear sides of the inner wall of the positive and negative threaded rod 15. The bottom of the two hanging plates 17 is fixedly installed with inclined positioning plates 18. The opposite surfaces of the two inclined positioning plates 18 overlap with the left and right sides of the glass fiber tube 5 respectively.

[0025] By rotating the knob 16 on the left side of the positioning plate 13, the positive and negative threaded rods 15 in the inner cavity of the clamping drive groove 14 can be rotated. The threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rods 15 are connected to the threads of the hanging plate 17, which can drive the two inclined positioning plates 18 to move closer to each other on the top of the conveyor belt 25 until they slightly touch the glass fiber tube 5 to avoid squeezing the glass fiber tube 5. This can limit the position of the glass fiber tube 5 and keep the glass fiber tube 5 stable, centered, grouting, rolling and shaping.

[0026] like Figure 3 As shown, a threaded hole 111 is provided in the horizontal position of the portal frame 11, and a threaded rod 112 is installed in the inner ring of the threaded hole 111. An adjustment knob 113 is fixedly installed at the top of the threaded rod 112. A portal plate 114 is movably installed at the bottom of the threaded rod 112. Fixed plates 115 are fixedly installed at the bottom of the two vertical positions of the portal plate 114. A rolling roller 116 is movably installed between the opposite surfaces of the two fixed plates 115. A servo motor 117 is fixedly installed on the left side of the left fixed plate 115. The output shaft of the servo motor 117 passes through to the right side of the left fixed plate 115 and is fixedly connected to the left center of the rolling roller 116. A limiting slide rod 118 is fixedly installed at the top of the horizontal position of the portal plate 114. The limiting slide rod 118 is located to the right of the threaded rod 112. The top of the limiting slide rod 118 is on the same horizontal line as the bottom of the adjustment knob 113. The limiting slide rod 118 is slidably connected to the horizontal position of the portal frame 11.

[0027] The threaded rod 112 can be rotated by adjusting the knob 113 above the horizontal position of the rotating gantry frame 11. The threaded connection between the threaded rod 112 and the threaded hole 111 drives the gantry plate 114 to descend stably using the limiting slide rod 118. This allows the rolling roller 116 between the opposing surfaces of the two fixed discs 115 to roll the rear end of the glass fiber tube 5, avoiding rolling the pre-embedded pipe 31. At this time, the glass fiber tube 5 can be conveyed backward while being rolled by the conveyor belt 25 in the conveying state and the rolling roller 116 driven by the servo motor 117.

[0028] like Figure 4 , Figure 5As shown, the conveying mechanism 2 includes two support legs 1 21 and two support legs 22. The two support legs 1 21 are located behind the two support legs 22, and the height of the two support legs 1 21 is greater than that of the two support legs 22. A drive roller 1 23 is movably installed between the upper surfaces of the two support legs 1 21 and the upper surfaces of the two support legs 22. A drive roller 24 is movably installed between the upper surfaces of the two support legs 22. A conveyor belt 25 is provided on the outer wall of the drive roller 1 23 and the drive roller 24. A crushing roller 116 is located above the top rear side of the conveyor belt 25. The two vertical opposite ends of the gantry frame 11 are fixedly connected to the opposite sides of the two support legs 1 21. The bottom of the fiberglass tube 5 is connected to the top of the conveyor belt 25. The bottom of the two inclined positioning plates 18 overlaps with the top of the conveyor belt 25. The output end of the filling machine 3 is fixedly connected to the pre-embedded pipe 31. The other end of the pre-embedded pipe 31 passes through the inner cavity of the glass fiber tube 5. The discharge mechanism 4 includes two L-shaped brackets 41. The front ends of the horizontal parts of the two L-shaped brackets 41 are fixedly installed on the rear side of the two support legs 21 respectively. The top of the vertical parts of the two L-shaped brackets 41 is fixedly installed with an inclined receiving plate 42. The inclined receiving plate 42 is located on the rear side of the conveyor belt 25 and its height is lower than that of the conveyor belt 25. The rear end of the inclined receiving plate 42 is fixedly connected to the ground contact plate 43. The left and right sides of the top of the inclined receiving plate 42 and the ground contact plate 43 are fixedly installed with side guard plates 44.

[0029] In use, the motor drives the first drive roller 23 and the second drive roller 24 to rotate, thereby driving the conveyor belt 25 to convey it to the rear. By placing the glass fiber tube 5 on top of the conveyor belt 25, the slurry can be injected into the inner cavity of the glass fiber tube 5 through the pre-embedded pipe 31 connected to the output end of the filling machine 3. As the glass fiber tube 5 is crushed and conveyed, the slurry in the pre-embedded pipe 31 gradually fills the entire glass fiber tube 5 and shapes it. The glass fiber tube 5 always moves in the center under the limit of the inclined positioning plate 18 until it falls onto the inclined receiving plate 42. Then, it slides down the inclined receiving plate 42 to the ground contact plate 43 to complete the discharge. The side guard plate 44 prevents the glass fiber tube 5 from sliding out of the inclined receiving plate 42. The inclined receiving plate 42 catches the glass fiber tube 5, which can effectively prevent the glass fiber tube 5 from bending and accumulating, and avoid the problem of uneven internal slurry.

[0030] The working principle of the auxiliary shaping device used in the production of CIPP tubing will be explained in detail below.

[0031] like Figures 1-5As shown, during use, the motor drives the first drive roller 23 and the second drive roller 24 to rotate, thereby driving the conveyor belt 25 to convey material to the rear. By placing the glass fiber tube 5 on top of the conveyor belt 25, the pre-embedded pipe 31 connected to the output end of the filling machine 3 can be used to fill the inner cavity of the glass fiber tube 5 with slurry. At the same time, by rotating the knob 16 on the left side of the positioning plate 13, the positive and negative threaded rods 15 in the inner cavity of the clamping drive groove 14 can be rotated. By using the threaded walls of the opposite threads on the left and right sides of the outer wall of the positive and negative threaded rods 15 to connect with the threads of the hanging plate 17, the two inclined positioning plates 18 can be driven to move closer to each other on the top of the conveyor belt 25 until they slightly touch the glass fiber tube 5 to avoid squeezing the glass fiber tube 5, thus limiting the position of the glass fiber tube 5. At this time, by rotating the adjustment knob 113 above the horizontal position of the gantry frame 11, the threaded rod 112 can be rotated. The threaded rod 112 and the threaded hole 111 are connected by the threads of the threaded rod 112. The connection drives the gate plate 114 to descend stably using the limiting slide bar 118, thereby allowing the rolling roller 116 between the opposing surfaces of the two fixed plates 115 to roll the rear end of the glass fiber tube 5, avoiding rolling the pre-embedded pipe 31. At this time, the glass fiber tube 5 can be conveyed backward while being rolled by the starting conveyor belt 25 and the rolling roller 116 driven by the servo motor 117. As the slurry in the pre-embedded pipe 31 gradually fills the entire glass fiber tube 5 and shapes it, the glass fiber tube 5 always remains centered under the limitation of the inclined positioning plate 18 until it falls onto the inclined receiving plate 42. Then, it slides down the inclined receiving plate 42 to the ground contact plate 43 to complete the discharge. The side guard plate 44 prevents the glass fiber tube 5 from sliding out of the inclined receiving plate 42. The inclined receiving plate 42 catches the glass fiber tube 5, which can effectively prevent the glass fiber tube 5 from bending and accumulating, avoiding the problem of uneven internal slurry.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
