Description

Technical Field

[0001] The present invention relates to the technical field of automated production equipment, and is a production system and preparation method for the main pipe of a fiberglass resin hose. Background Art

[0002] In trenchless pipeline repair technology, the in-situ curing method is one of the commonly used repair techniques; the in-situ curing method is a repair method that uses the flipping or pulling method to place a resin-impregnated hose into the original pipeline, and uses a heat source or ultraviolet light, etc. to cure it to form a new pipeline that closely fits the old pipe; the lining pipe is a fiberglass resin hose before being put into the underground pipeline, and the production process is mainly divided into two steps: the main pipe part of the lining pipe and the glue filling and rolling (wet pipe) part; the main pipe of the lining pipe is a multi-layer hose; mainly composed of an inner membrane layer, a fiberglass structure layer, an anti-seepage membrane layer, and a light-shielding protective film layer; among them, the fiberglass structure layer is formed by overlapping multiple layers of fiberglass cloth, and later resin glue is poured in and cured to become the stress-bearing structure layer of the lining pipeline; the function of the inner membrane layer is to inflate and expand the pipeline during lining repair, and make the lining pipe closely fit the inner wall of the original pipeline; the inner membrane layer and the anti-seepage membrane layer wrap the fiberglass and resin glue, restricting the flow of the resin glue to prevent its leakage, and the light-shielding protective film layer avoids the curing of the resin glue caused by ultraviolet light in the environment;

[0003] At present, almost all of the main pipe parts of domestic fiberglass hoses adopt the manual lapping pipe-making process, with low work efficiency, high labor intensity, and the fiberglass debris is harmful to the health of workers. More importantly, the manual lapping method cannot guarantee the precision of pipe making, and phenomena such as delamination, local wrinkles, cavities, bubbles, or uneven wall thickness occur after curing, greatly affecting the quality of the lining pipe after pipeline repair.

[0004] Secondly, the fiberglass cloth material required for the lapping pipe-making process is a customized material with fixed dimensions, and the dimensions of different pipe diameters, different wall thicknesses, and different layers are different, which will result in a huge variety of raw material specifications and a large inventory;

[0005] Thirdly, in the production process of the main pipe part of the lining pipe, for the fiberglass structure layer, a simple winding method is also used for production. When the lining pipe is pulled into the pipeline during construction, accidents such as the lining pipe being stretched or pulled off will occur under the condition of huge tensile force, seriously affecting the repair quality of the fiberglass lining pipe or causing the project to fail;

[0006] In addition to the above, the thickness of the fiberglass structure layer is the main performance index of the main pipe part of the lining pipe; when using the winding and lapping method to produce the fiberglass structure layer, the fiberglass thickness is determined by the overlapping density of the winding; therefore, how to efficiently and accurately control the winding and lapping thickness is the technical core of realizing the production using the winding and lapping method, and there is currently no reliable application method. Summary of the Invention

[0025] The second technical solution of the present invention is achieved by the following measures:

[0026] A preparation method using a glass fiber resin hose trunk production system, the steps are as follows:

[0027] Step 1, film selection;

[0028] The inner film is a cylindrical film with a diameter of 461mm; the outer diameter of the molding cylinder is 489cm;

[0029] The inner layer of glass fiber cloth is selected with a width of 600mm;

[0030] The width of the outer fiberglass cloth is 784mm;

[0032] The adhesive tape is a sheet-shaped adhesive tape with adhesive backing, with a width of 60mm;

[0033] Step 2, film installation;

[0034] Take the inner film roll and install it on the inner film roll rack, flatten the inner film and pull it out, use the film guiding tool to insert the inner film from left to right into the shaping mold cylinder, pull it out from the left end of the shaping mold cylinder, and leave the inner film end extending out of the right end of the shaping mold cylinder;

[0035] Take two inner glass fiber cloth turntables with inner glass fiber cloth, install them on the corresponding reel seats of the gear turntable respectively, flatten and pull out the inner glass fiber cloth, cross-wind it on the shaping mold cylinder until the right end of the shaping mold cylinder, and leave the end of the inner glass fiber structure layer extending out of the right end of the shaping mold cylinder;

[0036] Take the upper outer glass fiber cloth reel with the upper outer glass fiber cloth and the lower outer glass fiber cloth reel with the lower outer glass fiber cloth, and install them on the upper covering reel rack and the lower covering reel rack respectively. Unroll and pull out the upper outer glass fiber cloth and the lower outer glass fiber cloth, and wrap them around the inner glass fiber structure layer outside the right part of the sizing die cylinder from the upper and lower directions until the right end of the sizing die cylinder, leaving the ends of the upper outer glass fiber cloth and the lower outer glass fiber cloth extending outside the right end of the sizing die cylinder. Then, buckle the upper die cylinder and the lower die cylinder on the outside of the upper outer glass fiber cloth and the lower outer glass fiber cloth at the right part of the sizing die cylinder, and fix them by pressing. The protruding inner membrane end, the inner glass fiber structure layer end, and the ends of the upper outer glass fiber cloth and the lower outer glass fiber cloth are pressed into a three-layer flat-mouth film by the flat-mouth type outlet of the covering shaping cylinder.

[0037] Take the film wrapping reel with the anti-seepage membrane and install it on the first group of film wrapping machine racks. Unroll and pull out the anti-seepage membrane onto the film wrapping platform of the film wrapping machine rack. Place the three-layer flat-mouth film on the film wrapping platform and on the upper end of the anti-seepage membrane. When pulling the inner glass fiber structure layer, manually rotate the gear turntable to keep the inner glass fiber structure layer in a winding motion. Then, fold the front and rear sides of the anti-seepage membrane on the film wrapping platform and overlap them on the top of the three-layer flat-mouth film, and then send them into the plastic forming chamber together. At the plastic forming chamber, put the side edge of the anti-seepage membrane overlapping on the upper layer into the edge passing gap and push it into the forming chamber. After pulling it out from the forming chamber, stick the adhesive tape to the overlapping part on the top of the three-layer flat-mouth film for sealing. At this time, the anti-seepage membrane has completely wrapped the upper outer glass fiber cloth, the lower outer glass fiber cloth, the inner glass fiber structure layer, and the inner membrane to form a four-layer flat-mouth film.

[0038] Take the film wrapping reel with the light-shielding protective film and install it on the second group of film wrapping machine racks. Unroll and pull out the light-shielding protective film onto the film wrapping platform of the film wrapping machine rack. Place the four-layer flat-mouth film on the film wrapping platform and on the upper end of the light-shielding protective film. When pulling the inner glass fiber structure layer, manually rotate the gear turntable to keep the inner glass fiber structure layer in a winding motion. Then, fold the front and rear sides of the light-shielding protective film on the film wrapping platform and overlap them on the top of the four-layer flat-mouth film, and then send them into the plastic forming chamber together. At the plastic forming chamber, put the side edge of the light-shielding protective film overlapping on the upper layer into the edge passing gap and push it into the forming chamber. After pulling it out from the forming chamber, stick the adhesive tape to the overlapping part on the top of the four-layer flat-mouth film for sealing. At this time, the light-shielding protective film has completely wrapped the anti-seepage membrane, the upper outer glass fiber cloth, the lower outer glass fiber cloth, the inner glass fiber structure layer, and the inner membrane to form a five-layer flat-mouth film. This five-layer flat-mouth film is the finished product of the hose main pipe.

[0039] Then, lift the pressure roller, pull the five-layer flat-mouth film to the right into the film pressing gap, lower the pressure roller, and press the pressure roller and the traction guide roller tightly. The film loading is completed.

[0040] Step 3: Start the production of the DN500mm * 5mm hose main pipe and set the operating parameters; Select a guiding roller with an outer diameter of 300mm, and at the same time start the rotary power device and the traction power device. Set the rotational speed of the gear turntable at 20 r / min; Set the rotational speed of the guiding roller at 6.37 r / min to achieve a traction speed of 100 mm / min.

[0041] The following is a further optimization and improvement of the second technical solution of the above invention:

[0042] Step 4: Stack the pipes.

[0043] First, set the operating parameters; Set the conveying speed at 100 mm / min; The length of the trolley track 1303 is 2 meters, and the reciprocating average frequency of the stacking trolley 1302 is 1.5 times per hour; Start the inclined conveying device 1301. The hose main pipe is conveyed along the inclined conveying device 1301 to the upper end and then falls. The reciprocating movement of the stacking trolley 1302 stacks the hose main pipes layer by layer.

[0044] The structure of the present invention is reasonable and compact, and it is convenient to use; For the glass fiber resin hose main pipe production system and the preparation method thereof, the traction device provides traction for the inner membrane, the inner layer glass fiber cloth, the outer layer glass fiber cloth, and the outer protective film, and realizes the automatic production and processing of the main pipe by wrapping the inner membrane to the outer protective film layer by layer.

[0045] The outer layer glass fiber cloth coating device is used to wrap the upper outer layer glass fiber cloth and the lower outer layer glass fiber cloth on the upper and lower parts of the inner layer glass fiber structure layer. In this way, when it is in the inner layer glass fiber structure layer, it forms a functional whole with the upper outer layer glass fiber cloth and the lower outer layer glass fiber cloth. The pulling force acts on the inner layer glass fiber cloth, the upper outer layer glass fiber cloth, and the lower outer layer glass fiber cloth at the same time. Not only is most of the pulling force on the inner layer glass fiber structure layer dispersed, but also the pulling force is focused on the whole of the inner layer glass fiber cloth and the outer layer glass fiber cloth. In this way, it can completely avoid the inner layer glass fiber cloth being pulled off, which is more reliable than the traditional winding method.

[0046] The flat-mouth type outlet of the coating and shaping cylinder can make the upper outer layer glass fiber cloth, the lower outer layer glass fiber cloth, and the inner layer glass fiber cloth separated from the shaping die cylinder be plastically formed into a multi-layer flat tube film that can be wound into a roll through the flat mouth; By pulling the multi-layer flat tube film, the automatic film wrapping of the whole glass fiber resin hose main pipe production system and the preparation method is realized.

[0047] After the film is pulled out from the film reel, when passing through the folding and overlapping plastic film tool, it can be automatically folded and overlapped, and then sealed with an adhesive tape to complete the wrapping of the outer protective film, realizing automatic film wrapping; The degree of automation is high.

[0080] As attached Figure 1-7As shown in the figure, the outer layer glass fiber cloth covering device 16 includes a covering reel rack 1601, an upper outer layer glass fiber cloth reel 1602, a lower outer layer glass fiber cloth reel 1603 and a covering and shaping cylinder. The covering reel racks 1601 are respectively and fixedly installed on the front and rear sides of the right part of the shaping die cylinder 3. The upper outer layer glass fiber cloth reel 1602 and the lower outer layer glass fiber cloth reel 1603 are fixedly installed on the covering reel rack 1601. The upper outer layer glass fiber cloth reel 1602 is located directly above the shaping die cylinder 3; the lower outer layer glass fiber cloth reel 1603 is located directly below the shaping die cylinder 3. The upper outer layer glass fiber cloth 7 is wound on the upper outer layer glass fiber cloth reel 1602, and the lower outer layer glass fiber cloth 8 is wound on the lower outer layer glass fiber cloth reel 1603. A covering and shaping cylinder is installed outside the right end of the shaping die cylinder 3 to the right of the covering reel rack 1601. The left and middle parts of the covering and shaping cylinder are sleeved outside the shaping die cylinder 3 and form a shaping ring cavity with the shaping die cylinder 3. The right part of the covering and shaping cylinder is placed outside the right end of the shaping die cylinder 3 and is in a flat-mouth shape. The pulled-out section of the upper outer layer glass fiber cloth 7 is placed inside the upper part of the shaping ring cavity and wrapped outside the upper part of the inner layer glass fiber structure layer 6. The pulled-out section of the lower outer layer glass fiber cloth 8 is placed inside the lower part of the shaping ring cavity and wrapped outside the lower part of the inner layer glass fiber cloth 4.

[0081] Among them, the covering and shaping cylinder is used for the covering and positioning of the upper outer layer glass fiber cloth 7 and the lower outer layer glass fiber cloth 8, so that the flattened and pulled-out upper outer layer glass fiber cloth 7 can bend downward and wrap outside the upper part of the inner layer glass fiber cloth 4 at the shaping ring cavity, and the flattened and pulled-out lower outer layer glass fiber cloth 8 can bend upward and wrap outside the lower part of the inner layer glass fiber cloth 4, so that the upper outer layer glass fiber cloth 7, the lower outer layer glass fiber cloth 8 and the inner layer glass fiber cloth 4 form an integral unit. The pulling force acts on both the inner layer glass fiber cloth 4 and the outer layer glass fiber cloth at the same time. Not only most of the pulling force on the inner layer glass fiber cloth 4 is dispersed, but also the traction force is applied to the whole of the inner layer glass fiber cloth 4 and the outer layer glass fiber cloth. In this way, it can completely avoid the inner layer glass fiber cloth 4 being pulled off, which is more reliable than the traditional winding method.

[0082] Among them, the flat-mouth type outlet of the covering and shaping cylinder can make the upper outer layer glass fiber cloth 7, the lower outer layer glass fiber cloth 8 and the inner layer glass fiber cloth 4 separated from the shaping die cylinder 3 be plastically formed into a multi-layer flat tube film through the flat mouth. By pulling the multi-layer flat tube film, the automatic film covering of a complete set of multi-layer hose production device is realized.

The gland 1608 is fixedly installed at the upper end of the shaping die cylinder base 1607 through a die cylinder spring pressing mechanism and fixedly installs the upper die cylinder 1605 and the lower die cylinder 1606 together.

[0084] Among them, the upper die cylinder 1605 and the lower die cylinder 1606 that are buckled up and down are convenient for manual film threading on the one hand; on the other hand, by using the die cylinder spring pressing mechanism and the buckling of the upper and lower die cylinders, the upper outer glass fiber cloth 7, the inner glass fiber structure layer 6 and the lower outer glass fiber cloth 8 can be more closely attached in the covering and shaping cylinder, improving the wrapping property of the upper outer glass fiber cloth 7 and the lower outer glass fiber cloth 8 on the inner glass fiber structure layer 6, making the upper outer glass fiber cloth 7, the inner glass fiber structure layer 6 and the lower outer glass fiber cloth 8 form a whole, reducing the effect of traction on the inner glass fiber structure layer 6, and further avoiding the disconnection of the inner glass fiber structure layer 6.

The adhesive tape reel 1008 and the adhesive tape pressure roller 1011 are installed on the sealing frame 1005 from bottom to top at intervals; a guide roller spring pressing mechanism that can press the adhesive tape pressure roller 1011 onto the outer protective film is installed between the sealing frames 1005.

[0092] The guide roller spring clamping mechanism adopts existing well-known technology, or adopts a structure similar to the spring clamping mechanism of the mold cylinder in the utility model, that is, the elastic restoring force of the spring is used to press the adhesive tape pressure roller 1011 downward, applying a downward force to the adhesive tape 1009, so that the adhesive tape 1009 can better bond the overlapping parts of the outer protective film.

[0093] As attached Figure 1-7 As shown, the traction device 12 includes a traction frame 1201, a traction power device 1204, a traction guide roller 1203 and a pressure roller 1205; the traction frame 1201 is two and is symmetrically arranged at intervals in the front and rear directions, and a traction guide roller 1203 is installed between the front and rear traction frames 1201 through a guide roller shaft 1202, and the traction power device 1204 is installed on the traction frame 1201, and the power output end of the traction power device 1204 is transmitted to the traction guide roller 1203.

Unroll the upper outer glass fiber cloth 7 and the lower outer glass fiber cloth 8, and wrap them around the inner glass fiber structure layer 6 outside the right part of the shaping die barrel 3 from the upper and lower directions until the right end of the shaping die barrel 3, and leave the ends of the upper outer glass fiber cloth 7 and the lower outer glass fiber cloth 8 extending outside the right end of the shaping die barrel 3; then buckle the upper die barrel 1605 and the lower die barrel 1606 on the outside of the upper outer glass fiber cloth 7 and the lower outer glass fiber cloth 8 at the right part of the shaping die barrel 3, fix them with the pressing cover 1608, and the extended ends of the inner film 2, the inner glass fiber structure layer 6, and the upper outer glass fiber cloth 7 and the lower outer glass fiber cloth 8 are pressed into a three-layer flat-mouth film by the flat-mouth type outlet of the covering shaping cylinder;

[0113] Take the wrapping film reel 1007 equipped with the anti-seepage film 14 and install it on the first group of wrapping film racks 1001; flatten and pull out the anti-seepage film 14 onto the wrapping film platform of the wrapping film rack 1001, place the three-layer flat-mouth film on the wrapping film platform and on the upper end of the anti-seepage film 14. When pulling the inner glass fiber structure layer 6, manually rotate the gear turntable 1502 to keep the inner glass fiber structure layer 6 in a winding motion; then fold the front and rear sides of the anti-seepage film 14 on the wrapping film platform and overlap them on the top of the three-layer flat-mouth film and send them into the plastic forming chamber 1004 together. At the plastic forming chamber 1004, put the side edge of the anti-seepage film 14 lapped on the upper layer into the edge passing gap 1003 and push it into the forming chamber. After pulling it out from the forming chamber, stick the adhesive tape 1009 on the top lap joint of the three-layer flat-mouth film for sealing. At this time, the anti-seepage film 14 has completely wrapped the upper outer glass fiber cloth 7, the lower outer glass fiber cloth 8, the inner glass fiber structure layer 6, and the inner film 2 to form a four-layer flat-mouth film;

[0114] Take the wrapping film reel 1007 equipped with the light-shielding protective film 9 and install it on the second group of wrapping film racks 1001; flatten and pull out the light-shielding protective film 9 onto the wrapping film platform of the wrapping film rack 1001, place the four-layer flat-mouth film on the wrapping film platform and on the upper end of the light-shielding protective film 9. When pulling the inner glass fiber structure layer 6, manually rotate the gear turntable 1502 to keep the inner glass fiber structure layer 6 in a winding motion; then fold the front and rear sides of the light-shielding protective film 9 on the wrapping film platform and overlap them on the top of the four-layer flat-mouth film and send them into the plastic forming chamber 1004 together. At the plastic forming chamber 1004, put the side edge of the light-shielding protective film 9 lapped on the upper layer into the edge passing gap 1003 and push it into the forming chamber. After pulling it out from the forming chamber, stick the adhesive tape 1009 on the top lap joint of the four-layer flat-mouth film for sealing. At this time, the light-shielding protective film 9 has completely wrapped the anti-seepage film 14, the upper outer glass fiber cloth 7, the lower outer glass fiber cloth 8, the inner glass fiber structure layer 6, and the inner film 2 to form a five-layer flat-mouth film; this five-layer flat-mouth film is the finished product of the hose main pipe;

[0115] Then lift the pressure roller 1205, pull the five-layer flat-mouth film to the right into the film pressing gap, lower the pressure roller 1205, and press the pressure roller 1205 and the traction guide roller 1203 tightly. The film installation is completed;

[0116] Step 3, start and set the operating parameters for producing the DN500mm * 5mm hose main pipe; select the traction guide roller 1203 with an outer diameter of 300mm, start the rotary power device 1510 and the traction power device 1204 at the same time, and set the rotation speed of the gear turntable 1502 at 20 r / min; set the rotation speed of the traction guide roller 1203 at 6.37 r / min to achieve a traction speed of 100 mm / min;

[0117] When the traction guide roller 1203 pulls the five-layer flat-mouth film to the right, the inner film 2 automatically unwinds; at the same time, the inner layer fiberglass cloth 4 automatically unwinds and rotates with the gear turntable 1502, and the inner layer fiberglass cloth 4 is wound around the shaping die barrel 3 to form the inner layer fiberglass structure layer 6; at the same time, the upper outer layer fiberglass cloth 7 and the lower outer layer fiberglass cloth 8 automatically unwind and then wrap around the upper and lower parts of the thermosetting material film 4; at the same time, the anti-seepage film 14 automatically unwinds and is automatically wrapped at the first set of folding and overlapping plastic molds 1002; at the same time, the light-shielding protective film 9 automatically unwinds and is automatically wrapped at the second set of folding and overlapping plastic molds 1002; at the same time, the two groups of adhesive tapes 1009 automatically unwind and are pasted on the top of the anti-seepage film 14 and the light-shielding protective film 9 for overlapping sealing.

[0118] When using this system in the production of a DN500mm*5mm hose, by selecting the film and setting the start-up operation parameters according to the above method, seamless half-lap winding overlap of the inner layer fiberglass cloth 4 on the shaping die barrel 3 can be achieved, and the formed inner layer fiberglass structure layer 6 has a uniform thickness and no delamination, thus achieving the purpose of efficient and precise control of winding overlap; using this system, it can also be used for the processing and production of hose mains with a width of 600mm and 800mm. For hose mains with a width of 600mm and 800mm, the operating parameters need to be reset to achieve high production accuracy, stable quality, and reliability of the inner liner.

[0119] According to actual needs, the preparation method can be further optimized and improved:

[0121] Start the inclined conveying device 1301. The hose main is conveyed along the inclined conveying device 1301 to the upper end and then falls. The reciprocating movement of the stacking trolley 1302 stacks the hose mains layer by layer. In this way, the outer packaging size of the stacked dry film width can be controlled within 2200mm, which is more convenient for transportation.
