DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figure 1 A fiberglass pipe socket pasting device comprises: a base 1, two glue spraying assemblies 26 are installed on the top wall of the base 1 (the glue spraying assemblies 26 include a bracket, a nozzle arranged on the bracket and a storage box connected with the nozzle), and two support assemblies are symmetrically installed on the top wall of the base 1, wherein the support assembly comprises a first bracket 2 and a second bracket 3, two groups of first driving members 6 (such as electric telescopic rods) are installed on the top walls of the first bracket 2 and the second bracket 3, and arc-shaped support blocks 4 are installed on the moving ends of the two groups of first driving members 6 (the tops of the first bracket 2 and the second bracket 3 have two arc-shaped support blocks 4); guide wheels 5 are rotatably provided on the two arc-shaped support blocks 4, the guide wheel 5 on one arc-shaped support block 4 is a first guide wheel, and the first guide wheel is used to drive the pipeline to rotate on the arc-shaped support block 4 (so that the pipeline rotates with the axis of the pipeline as the center of the circle), and the guide wheel 5 on the other arc-shaped support block 4 is a second guide wheel, and the second guide wheel is used to drive the pipeline to move, so that the two pipelines placed on the two support assemblies are close to or away from each other.

[0038] It should be noted that when the cut pipe needs to be placed on the support assembly, a set of first driving members 6 contracts to move the arc-shaped support block 4 with the second guide wheel downward, lowering the height of the second guide wheel, and then place the pipe on the support assembly, at which time the first guide wheel is in contact with the pipe; during the process of grinding and gluing the pipe, the first guide wheel can rotate with the pipe to facilitate the work; when the two pipes need to be connected, the first driving member 6 drives the arc-shaped support block 4 with the second guide wheel to move upward, so that the second guide wheel fits the pipe, and then the first driving member 6 drives the arc-shaped support block 4 with the first guide wheel to move downward, so that the first guide wheel does not contact the pipe, so that the first guide wheel will not cause obstruction when the second guide wheel moves with the pipe.

[0039] It should also be noted that the two first brackets 2 are located on the inner side of the two second brackets 3; and the second brackets 3 are slidably mounted on the top wall of the base 1 (the second bracket 3 is fixed to the base 1 by bolts), so that the distance between the first bracket 2 and the second bracket 3 can be adjusted as needed to accommodate pipe supports of different lengths.

[0040] See also Figure 1 and Figure 2 A motor is installed on the arc-shaped support block 4 on which the first guide wheel is installed, and the output shaft of the motor is connected to the first guide wheel for driving the guide wheel to rotate; two driving assemblies are installed on the top wall of the base 1, and the two driving assemblies are respectively used to drive a second guide wheel on the two first brackets 2 to rotate;

[0041] Among them, see Figure 4 The driving assembly 7 includes an installation box 71, a transmission wheel 72, and a second conveyor belt 73. The transmission wheel 72 is rotatably installed in the inner cavity of the installation box 71, and the transmission between the transmission wheel 72 and the second guide wheel is transmitted through the second conveyor belt 73; an elastic telescopic rod 75 is provided in the inner cavity of the installation box 71 (the elastic telescopic rod 75 includes a telescopic mother rod, a telescopic child rod slidably inserted in the telescopic mother rod, and a spring provided between the telescopic mother rod and the telescopic child rod), and a tensioning wheel 74 is provided on the movable end of the elastic telescopic rod 75. The tensioning wheel 74 is located on the inner side of the second conveyor belt 73 and is in contact with the second conveyor belt 73; the shaft of the transmission wheel 72 A driving gear 76 is provided on it, and two driving gears 76 are driven by the gear rod 12; a motor is installed on an installation box 71, and the output shaft of the motor is connected to the driving wheel 72 on the installation box 71; the motor drives the driving wheel 72 to rotate, and through the second conveyor belt 73, the second guide wheel will rotate, and when one driving wheel 72 is driven to rotate by the motor, it is driven by the gear rod 12, which will make the driving wheel 72 in the other installation box 71 also rotate synchronously, and through the second conveyor belt 73, the second guide wheel here will rotate, which is used to guide the two pipes on the two supporting assemblies to move closer to or away from each other.

[0042] It should be noted that when the first driving member 6 drives the arc-shaped support block 4 to rise and fall and changes the height of the second guide wheel, the distance between the second guide wheel and the transmission wheel 72 will change. For example, when the second guide wheel moves downward, the distance between the second guide wheel and the transmission wheel 72 decreases, so that the second conveyor belt 73 is relaxed. At this time, the elastic telescopic rod 75 contracts and moves with the tensioning wheel 74 to pull the second conveyor belt 73 in to prevent the second conveyor belt 73 from detaching from the second guide wheel and the transmission wheel 72; when the second guide wheel moves upward, the elastic telescopic rod 75 extends to cause the tensioning wheel 74 to move in the opposite direction.

[0043] In this embodiment, as a further optimized solution, please refer to Figure 2 , two mounting blocks 8 are slidably provided on one side wall where the two first brackets 2 are close to each other, and a second driving member 24 (such as a cylinder) is installed on the first bracket 2. The moving end of the second driving member 24 is connected to the mounting block 8, which is used to drive the two mounting blocks 8 on the same side to move closer to or away from each other, and a clamping plate 9 is provided on the top wall of the mounting block 8; when the pipeline needs to be connected, the second driving member 24 first moves the mounting block 8, so that the two mounting blocks 8 on the same side are close to each other, and the clamping plate 9 moves with the side wall of the pipeline to restrict the pipeline, so that the pipeline will not deviate when moving closer, further ensuring that the two pipelines are successfully docked at one time.

[0044] In this embodiment, as a further optimized solution, please refer to Figure 2 and Figure 3 A slot 23 is provided at the end of the mounting block 8 on one side, and a travel switch 25 is provided in the inner cavity of the slot 23. The travel switch 25 is used to control the start of the motor of the drive assembly 7. An insert block 10 is provided on the mounting block 8 on the other side, and the mounting block 8 is connected to a pushing device (such as a cylinder), and the mounting block 8 is driven by the pushing device to move closer to the mounting block 8 on the other side; after the splint 9 is fitted with the pipeline, the pushing device is started to drive the mounting block 8 to move with the insert block 10 until the insert block 10 is inserted into the inner cavity of the slot 23 and contacts the travel switch 25, so that the drive assembly 7 is started, the second guide wheel is controlled to rotate, and the pipeline is transported. At this time, the two pipelines are aligned; if the two pipelines are not aligned, the insert block 10 cannot be inserted into the slot 23, so that the drive assembly 7 is not started, which has a detection effect to ensure that the two pipelines can be docked at one time.

[0045] It should be noted that the second driving member 24 first drives the installation block 8 to move, and the moving distance is fixed. After the installation block 8 moves to the preset position, the second driving member 24 stops working, and the device is pushed to start.

[0046] In this embodiment, as a further optimized solution, please refer to Figure 2, an arc-shaped clamping block 11 is provided on one side wall where two clamping plates 9 are close to each other, and the clamping plate 9 with the arc-shaped clamping block 11 is slidably installed on the mounting block 8, and the moving direction of the clamping plate 9 is the same as the moving direction of the pipeline, and an electromagnet 13 is provided on the side wall of the clamping plate 9 on the other side, and the electromagnet 13 is controlled and started by the travel switch, and the clamping plate 9 is made of a metal that can be magnetically adsorbed (such as iron); when the mounting block 8 moves with the clamping plate 9 to approach the side wall of the pipeline, the arc-shaped clamping block 11 will fit with the outer wall of the pipeline; when the plug-in block 10 is inserted into the slot 23 and contacts the travel switch 25 to trigger it, the electromagnet 13 is energized to generate a magnetic force, which is used to attract the clamping plate 9 with the arc-shaped clamping block 11, so that the clamping plate 9 moves with the arc-shaped clamping block 11 on the outer wall of the pipeline, and is used to scrape off the mixed adhesive on the outside of the pipeline connection after the pipeline is connected.

[0047] It should be noted that, in order to ensure that the arc clamp 11 starts to move after the pipeline is connected, a controller is installed on the electromagnet 13. After receiving the information that the travel switch is triggered, the controller delays for a period of time and then controls the electromagnet 13 to be energized.

[0048] In this embodiment, as a further optimized solution, please refer to Figure 5 and Figure 6 , an arc-shaped scraper block 14 is provided on the arc-shaped scraper block 14, a moving block 15 is provided on the arc-shaped scraper block 14, the moving block 15 is slidably arranged on the arc-shaped clamping block 11, and an elastic member 16 (spring) is provided between the moving block 15 and the arc-shaped clamping block 11; a roller 17 is rotatably provided at the bottom of the clamping plate 9 with the arc-shaped clamping block 11, and the roller 17 is fitted with the mounting block 8, and a first rotating shaft 19 is rotatably provided on the clamping plate 9, and the first rotating shaft 19 and the axis of the roller 17 are transmitted through a first conveyor belt 18; a second rotating shaft 20 is rotatably provided on the arc-shaped clamping block 11, and a connecting rope 22 is provided between the second rotating shaft 20 and the moving block 15, a toothless gear 21 is provided on the first rotating shaft 19, and a driven gear is provided on the second rotating shaft 20, and the driven gear is meshed with the toothless gear 21; when the electromagnet 13 attracts the clamping plate 9 with the arc-shaped clamping block 11, the arc-shaped clamping block 11 is provided with a second rotating shaft 20, and the second rotating shaft 20 is provided with a driven gear, and the driven gear is meshed with the toothless gear 21; When the plate 9 moves, the roller 17 moves and rotates on the mounting block 8, and is transmitted through the first conveyor belt 18 to rotate the first rotating shaft 19. Since the toothless gear 21 is meshed with the driven gear, the second rotating shaft 20 is rotated by the first rotating shaft 19, and the connecting rope 22 is wound around the outer wall of the second rotating shaft 20, so that the moving block 15 moves the arc scraper block 14 on the arc clamping block 11, and the arc scraper block 14 rotates with the axis of the pipeline as the center of the circle); as the first rotating shaft 19 continues to rotate, the toothless gear 21 is not meshed with the driven gear, and the force acting on the second rotating shaft 20 disappears. Under the action of the elastic member 16, the moving block 15 moves the arc scraper block 14 in the opposite direction and resets, so that the arc scraper block 14 moves back and forth, which is used to clean the mixed adhesive outside the pipeline connection to increase the cleaning effect.

[0049] A method for gluing a glass fiber reinforced plastic pipe socket, comprising the following steps:

[0050] First, measure the required length of the pipe, mark the cutting location with a white marker, clamp and protect the pipe with cloth or rubber material, use a hacksaw or electric grinder to cut the pipe, and then use a clean rag and brush to remove burrs, dirt, debris and other debris;

[0051] Second, the first driving member 6 is retracted to move the arc-shaped support block 4 with the second guide wheel downward to reduce the height of the second guide wheel. Then, after placing the two pipes on the two support assemblies respectively, a 40-grade or 60-grade diamond sandpaper is used to grind the outer opening of one pipe ( Figure 7 ) and sandpaper inner grinding head to the inner mouth of another pipe ( Figure 8 ) for polishing;

[0052] It should be noted that the outer opening of the pipe at the insertion end of the socket should be polished to a length not less than the insertion length and to a taper angle ( Figure 7 ); Grind the inner mouth of the pipe at the socket and the depth of grinding should be less than 0.3mm;

[0053] Third, the surface of the bonding interface (inner and outer ports) after grinding should present a dull finish. Use a hair dryer to blow away dust and other impurities on the bonding interface, and use acetone to clean it if necessary; before bonding, the cleaned bonding interface surface must not be contaminated by oil, moisture or hands; bonding should be carried out within 1 hour after surface treatment (if the time is exceeded and the surface is contaminated or wet, it must be re-cleaned and re-grinded with a brush or clean cloth);

[0054] Fourth, apply a thin and even layer of mixed adhesive to the newly prepared interface surface for the first time, with a thickness of 0.5mm. Do not apply too much adhesive to avoid forming too much adhesive inside the joint; apply the glue evenly on the surface of the bonding interface after the first application, and make sure there is no dust, sand, or other particles on the surface of the adhesive, and then apply the glue for the second time. The second mixed adhesive is evenly applied with a thickness of 1.0mm;

[0055] It should be noted that the mixed adhesive is mixed and prepared in proportion, the resin mixture is 100 parts by weight of resin and 24 parts by weight of hardener, the temperature of the mixture of resin and hardener should not exceed 25°C, the resin and hardener of the mixed adhesive should be stirred in a dry container for 2-3 minutes until the color of the mixture is uniform; the mixed adhesive should be bonded within 10 minutes in an environment below 40°C; the glue spraying assembly 26 is used in the process of glue spraying;

[0056] Fifth, after ensuring that there is no dust, sand, or other particles on the inner and outer surfaces of the adhesive, the first driving member 6 drives the arc-shaped support block 4 with the second guide wheel to move upward, so that the second guide wheel fits the pipe, and then the first driving member 6 drives the arc-shaped support block 4 with the first guide wheel to move downward, so that the first guide wheel does not contact the pipe, and the second guide wheel rotates to drive the pipe to move, so that the end of one pipe is inserted into the end of the other pipe ( Fig. 9 );

[0057] It should be noted that the grinding length of the inner opening of the pipe is L, the length of the outer opening of the pipe inserted into the inner opening of the pipe is H, H is smaller than L, and the difference between L and H is S. By leaving a gap (S), the mixed adhesive will not be squeezed into the interior of the pipe;

[0058] Sixth, tighten the connected pipes (after the sockets are bonded, the two ends of the sockets are fixed to the two sides of the pipes with locks and lock belts, and wooden blocks are used to prevent the lock belts from contacting the pipes. The fastening device can be removed only after the mixed adhesive has cured).

[0059] Seventh, after the socket is bonded, tightened and hardened, heat-assisted curing should be carried out as soon as possible. Wrap the 220V AC heating pad around the outside of the socket, fix the heating pad with a rope for heating, which can better promote the bonding effect of the adhesive; the heating temperature is 125°C, and the heating time is determined by the thickness of the pipe wall, generally between 1.5 and 3 hours. Records should be made during the heating and curing process, and the temperature should be recorded every 10 minutes. After completion, disconnect the power supply and wait for 30 minutes. After the temperature of the socket drops to ambient temperature, remove the heating pad.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
