Description

Technical Field

[0001] The invention relates to the technical field of basalt fiber composite pipe preparation, and in particular to a basalt fiber composite pipe preparation device and a preparation method. Background Art

[0002] Basalt fiber composite pipe is a new type of high-tech composite pipe made of basalt fiber as the main material. It has the advantages of corrosion resistance, high strength, light weight, and green environmental protection. The existing basalt fiber composite pipe preparation device usually includes: fiber feeding system, glue spraying device, resin impregnation tank, rolling forming mold and curing furnace. The fiber feeding system evenly feeds the basalt fiber into the preparation area, the glue spraying device sprays adhesive on the fiber surface to ensure good adhesion, the resin impregnation tank impregnates the glue-sprayed fiber into the resin to ensure full infiltration, and the rolling forming mold forms the impregnated fiber into a tube. Finally, the curing furnace heats and cures the composite pipe to achieve its final strength and stability.

[0003] The Chinese patent number is 202310064523.1, and its name is "A rotary composite molding device for basalt fiber composite tubes". The fiber composite tube is continuously moved by a traction mechanism, and the bristles on the inner wall of the inner wheel brush and clean the outer wall of the fiber composite tube. The continuously moving fiber composite tube drives the roller and the bristle roller to roll. When the magnetic strips arranged at intervals on the roller are opposite to the magnetic glue release head, the same magnetism will repel each other. Therefore, the magnetic glue release head will overcome the resistance of the elastic airbag and move upward, and then the discharge port will open, and the glue in the glue squeeze bottle will flow out quantitatively and regularly, and the outer wall of the fiber composite tube will be evenly coated with the rotating bristle roller. The fiber composite tube after gluing is in contact with the scraper, and the rubber scraper will not scratch the fiber composite tube, and then the excess glue will be scraped off, thereby solving the problems of the traditional rotary composite molding device of basalt fiber composite tubes that cannot be automatically glued, excessive glue, and glue cannot be collected.

[0004] However, the current molding device has the following problems: after the device sprays glue on the basalt fiber composite tube, when the basalt fiber composite tube moves driven by the traction mechanism, some glue will drip onto the inner wall of the inner tube. After long-term use, the glue will accumulate on the inner wall of the inner tube, and it is easy to adhere to the outer wall of the subsequent basalt fiber composite tube, and additional cleaning or trimming work is required, which increases the production cycle and cost.

[0014] Furthermore, a limiting sliding groove is provided on the inner wall of the middle part of the hollow cylinder along the axial direction, and a limiting sliding block which is slidably matched with the limiting sliding groove is provided on the outer side of the slip ring.

[0015] Furthermore, the end surface of the smear block close to the slip ring is provided with a plurality of arc blocks 1 at intervals, and the end surface of the slip ring is provided with arc blocks 2 corresponding to the arc blocks 1 at intervals.

[0016] Further, it also includes a cleaning agency;

[0018] The present invention also provides a method for preparing a basalt fiber composite tube, comprising the following steps:

[0019] S1. The basalt fiber composite tube is pulled into the interior of the hollow cylinder by a pulling mechanism, and then the surface of the moving basalt fiber composite tube is sprayed with glue by a glue spraying box;

[0020] S2. When the basalt fiber composite tube moves, it will push the scraping mechanism to move, and the scraping mechanism will rotate when it moves. The scraping mechanism moves and rotates to scrape the glue on the inner wall of the hollow cylinder;

[0021] S3. When the scraping mechanism rotates, it slides along the coating mechanism and drives the coating mechanism to rotate. The glue on the surface of the basalt fiber composite tube can be evenly coated through the coating mechanism.

[0022] The present invention has the following beneficial effects:

[0023] 1. The present invention sets a scraping mechanism, and through the cooperation of a fixed plate, an L-shaped plate, a scraping ring, a push block, a screw, a limit block, and a spring, the basalt fiber composite tube moves along the hollow cylinder under the action of the traction mechanism, the basalt fiber composite tube moves and pushes the push block to move, and the push block pushes the screw to move and rotate along the fixed plate, thereby driving the push block and the scraping ring to rotate and move to scrape off the glue that falls on the inner wall of the hollow cylinder when the previous basalt fiber composite tube is sprayed, thereby avoiding glue accumulation and affecting subsequent basalt fiber composite tubes, reducing additional cleaning or trimming work, and saving production cycle and cost problems.

[0024] 2. The present invention sets a scraping cleaning mechanism, through the cooperation of the scraper ring, the fixed ring, the resistance block, the scraper, the long rod and the spring. When the scraper ring moves and rotates and contacts the scraper, the scraper will scrape off the glue on the surface of the scraper ring, thereby preventing the glue on the scraper ring from adhering to the inner wall of the hollow cylinder again when the scraper ring is reset.

[0025] 3. The present invention sets a smearing mechanism, and cooperates with a moving ring, a rotating ring, a sliding rod, a smearing block, a sliding ring, and a baffle. When the basalt fiber composite tube pushes the scraping mechanism to scrape the glue on the inner wall of the hollow cylinder, the moving ring can be driven to move along the hollow cylinder under the elastic force of spring three, thereby pushing the rotating ring, the sliding rod, the smearing block, and the baffle to move. At this time, the glue outlet of the glue spray box is opened, and the glue flows out to the outer wall of the basalt fiber composite tube. At the same time, the sliding rod drives the smearing block and the rotating ring to rotate, and the glue is evenly smeared through the smearing block; when the scraping mechanism is driven to reset under the action of spring one, the screw and other components will push the baffle to reset, and the baffle blocks the glue outlet of the glue spray box.

[0026] 4. The present invention arranges arc block 1 on the smear block and arc block 2 on the slip ring. When the rotation of arc block 1 does not conflict with arc block 2, spring 4 will drive the smear block to reset through its own elastic force. When arc block 1 conflicts with arc block 2, the smear block compresses spring 4, and so on, so that the smear block can realize reciprocating motion, so that the smear block can more evenly spread the glue on the surface of the basalt fiber composite tube.

[0027] 5. The present invention provides a cleaning mechanism, so that the electric telescopic rod, the connecting frame, the track block, the slider and the pressure ring cooperate to make the pressure ring move back and forth and clean the adhesion on the surface of the basalt fiber composite tube, thereby ensuring good contact between the glue and the surface of the basalt fiber composite tube, and preventing the adhesion on the surface of the basalt fiber composite tube from interfering with the curing process of the glue, resulting in poor bonding or glue falling off.

[0038] like Figure 4 and Figure 5 As shown, a plurality of connecting blocks 41 are arranged at annular intervals inside the end of the hollow cylinder 4 close to the traction mechanism 2; the smearing mechanism 7 includes a moving ring 71 slidably arranged in the hollow cylinder 4, a spring three 72 connected between the moving ring 71 and the connecting block 41, and a rotating ring 73 rotatably connected to the side of the moving ring 71 away from the spring three 72, an annular groove is provided on the side of the moving ring 71 close to the rotating ring 73, and a protrusion is provided on the rotating ring 73 that slidably cooperates with the annular groove of the moving ring 71, thereby realizing its rotation; two sliding rods 74 are symmetrically arranged on the side of the rotating ring 73 away from the moving ring 71, and the ends of the two sliding rods 74 away from the rotating ring 73 pass through the push block 64 and extend to the outside of the hollow cylinder 4, and the push block 64 is provided with a sliding hole that slidably cooperates with the sliding rod 74; sliding A smear block 75 is arranged on the slide bar 74, and an axial hole matching the slide bar 74 is opened on the smear block 75. The smear block 75 is sleeved on the slide bar 74, and a spring four 77 is connected between the smear block 75 and the rotating ring 73, and the spring four 77 is sleeved on the corresponding slide bar 74; and a slip ring 76 is slidably arranged in the hollow cylinder 4 and corresponding to the smear block 75, the slip ring 76 is located on the outside of the two slide bars 74, and a baffle 78 for blocking the glue outlet of the glue spray box 5 is arranged on the side of the slip ring 76 away from the smear block 75, and the end of the baffle 78 is in contact with the scraper ring 63; in order to limit the rotation of the slip ring 76, a limiting slide groove (not shown) is opened axially on the middle inner wall of the hollow cylinder 4, and a limiting slider 761 slidably matched with the limiting slide groove is arranged on the outside of the slip ring 76.

[0039] When in use, the basalt fiber composite tube is pulled into the interior of the hollow cylinder 4 by the traction mechanism 2, and then the surface of the moving basalt fiber composite tube is sprayed with glue by the glue spraying box 5. When the basalt fiber composite tube moves, it will push the push block 64 in the scraping mechanism 6 to move, and the movement of the push block 64 will drive the scraper ring 63 and the screw 65 to move. When the screw 65 moves, it will rotate on the fixed plate 61. The screw 65 will compress the spring 1 67 through the limit block 66 at the same time. The rotation of the screw 65 will drive the push block 64 and the scraper ring 63 to rotate together, so that the glue dropped on the inner wall of the hollow cylinder 4 when the previous basalt fiber composite tube is sprayed with glue can be scraped off by the scraper ring 63 while rotating and moving, and glue accumulation and influence on the subsequent basalt fiber composite tubes can be avoided, thereby reducing additional cleaning or finishing work, saving production cycle and cost problems. When the glue spraying of a basalt fiber composite tube is completed, the spring 1 67 will drive the screw 65, the push block 64 and the scraper ring 63 to reset.

At the same time, the movement of the smear block 75 pushes the arc block 2 762 and the slip ring 76 to move through the arc block 1 751, and the movement of the slip ring 76 pushes the baffle 78 away from the nozzle of the glue spray box 5. At the same time, the rotation of the push block 64 will drive the sliding rod 74 to rotate, and the rotation of the sliding rod 74 will drive the smear block 75 to rotate, and the rotation of the smear block 75 will drive the arc block 1 751 to rotate. When the smear block 75 is rotated, the rotation of the arc block 1 751 will conflict with the arc block 2 762, so that the smear block 75 compresses the spring 4 77. When the rotation of the arc block 1 751 does not conflict with the arc block 2 762, the spring 4 77 will reset the smear block 75 by its own elastic force, and so on, so that the smear block 75 can achieve reciprocating motion, so that the smear block 75 can more evenly spread the glue on the surface of the basalt fiber composite tube; when the spring 1 67 resets the screw 65 and other components by its own elastic force, the reset of the screw 65 and other components will drive the baffle 78 to reset, and the glue outlet of the glue spray box 5 is blocked by the baffle 78.

When the scraper ring 63 rotates and moves and contacts the scraper 83, the push rod 641 will push the resistance block 82 to drive the fixed ring 81 to move. At this time, the spring 2 85 is compressed and the spring 2 85 plays a buffering role. The scraper 83 will scrape off the glue on the surface of the scraper ring 63, thereby preventing the glue on the surface of the scraper ring 63 from adhering to the inner wall of the hollow cylinder 4 again. The spring 2 85 can drive the fixed ring 81 and other components to reset.

In this way, the electric telescopic rod 92 can be extended and retracted to drive the pressure ring 96 to move back and forth and clean the adhesion on the surface of the basalt fiber composite tube, thereby ensuring good contact between the glue and the surface of the basalt fiber composite tube, and preventing the adhesion on the surface of the basalt fiber composite tube from interfering with the curing process of the glue, resulting in poor bonding or glue falling off.

[0043] Another embodiment of the present invention provides a method for preparing a basalt fiber composite tube, comprising the following steps:

[0044] S1, the basalt fiber composite tube is pulled into the interior of the hollow cylinder 4 by the pulling mechanism 2, and then the surface of the moving basalt fiber composite tube is sprayed with glue by the glue spraying box 5;

[0045] S2. When the basalt fiber composite tube moves, it pushes the scraping mechanism 6 to move. When the scraping mechanism 6 moves, it rotates. The scraping mechanism 6 moves and rotates to scrape the glue on the inner wall of the hollow cylinder 4.

[0046] When the basalt fiber composite tube moves, it will push the push block 64 to move, and the movement of the push block 64 will drive the scraper ring 63 to move. The movement of the push block 64 will push the screw 65 to move and rotate on the fixed plate 61. The movement of the screw 65 will compress the spring 67, and the rotation of the screw 65 will drive the push block 64 and the scraper ring 63 to rotate, so that the scraper ring 63 rotates and moves to scrape off the glue that fell on the inner wall of the hollow cylinder 4 when the previous basalt fiber composite tube was sprayed with glue, thereby avoiding glue accumulation and affecting the subsequent basalt fiber composite tubes, reducing additional cleaning or trimming work, and saving production cycle and cost.

[0047] S3, when the scraping mechanism 6 rotates, it slides along the coating mechanism 7 and drives the coating mechanism 7 to rotate, so that the glue on the surface of the basalt fiber composite tube can be evenly coated through the coating mechanism 7.
