Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic pipe production, in particular to a pipe body deviation correcting device used in glass fiber reinforced plastic pipe production. Background Art

[0002] FRP pipe, also known as glass fiber wound sand-filled pipe, mainly uses glass fiber and its products as reinforcing materials, high molecular weight unsaturated polyester resin, epoxy resin and other basic materials, and quartz sand, calcium carbonate and other inorganic non-metallic granular materials as fillers as the main raw materials.

[0003] During production, FRP pipes need to be transported between the production line and the warehouse. Currently, they are usually transported by roller conveyors. Since the FRP pipes just off the production line have not yet reached the predetermined strength after curing, it is necessary to prevent the FRP pipes from deviating from the conveyor and colliding with the side wall of the conveyor and causing deformation during transportation.

[0004] After searching, a Chinese patent with publication number: CN116812484A discloses a pipe body correction device for the production of glass fiber reinforced plastic sand-filled pipes, including a pipe body and a base, characterized in that a groove 1 is opened at the upper end of the base, a first transmission mechanism, a second transmission mechanism and a correction mechanism are arranged in the groove 1, a first transmission mechanism is arranged at the lower end of the groove 1, inclined surfaces are opened at the lower ends of both sides of the inner wall of the groove 1 and a second transmission mechanism is arranged, and correction mechanisms are arranged on both sides of the inner wall of the groove 1.

[0005] The Chinese patent with publication number: CN114803418A discloses a correction device for the production of glass fiber reinforced plastic sand-filled pipes and a method of using the same, comprising a frame, a first adjustment component fixedly connected to the frame, the first adjustment component comprising a sliding component fixedly connected to the frame, a first bracket fixedly connected to the sliding component, a second adjustment component sleeved on the outer surface of the first connecting component, the second adjustment component being slidably connected to the first connecting component, and a correction roller being rotatably connected to the second adjustment component.

[0006] Based on the above search and combined with actual problems, it is found that the existing correction device usually installs multiple rollers on both sides of the conveyor, and clamps the two sides of the FRP pipe through the rollers on both sides, so as to prevent the FRP pipe from deviating. However, since the FRP pipe has just been produced, its strength has not yet reached the design standard. Therefore, the FRP pipe is continuously clamped and squeezed by multiple rollers on both sides during transportation, which not only easily causes the FRP pipe to deform and reduce the roundness of the cross-section, but also increases the transmission resistance of the FRP pipe, resulting in grinding between the conveying rollers and the FRP pipe, thereby aggravating the wear on the surface of the FRP pipe. Summary of the invention

[0010] Preferably, a plurality of guide grooves are provided on the outer side of the conveying roller, and a plurality of the connecting blocks are respectively penetrated and slidably connected to the inner sides of the plurality of guide grooves.

[0011] Preferably, one side of the inner slide plate is elastically connected to both ends of the inner side of the conveying roller through a centering spring.

[0012] Preferably, the two side rollers are rotatably mounted on one end of the two telescopic rods through roller frames, one end of the two telescopic rods is fixed with a piston plate slidably connected to the inner side of the piston cylinder, one side of the two roller frames is fixed with a guide rod, and each guide rod is slidably inserted into the inside of a column at a corresponding position.

[0013] Preferably, a plurality of damping exhaust holes are provided on the outer sides of the two piston cylinders at one end close to the roller frame.

[0014] Preferably, one side of the two piston plates is elastically connected to the inner ends of the two piston cylinders respectively through return springs.

[0015] Preferably, two through holes are provided at both ends of the air guide cylinder, and a plurality of exhaust notches are provided at both ends of the air guide cylinder near the two ends of the sliding column.

[0016] Preferably, the air source device comprises an air pump and an air tank connected to one end of the air inlet pipe, and the air outlet end of the air pump is connected to the interior of the air tank.

[0017] Preferably, the driving mechanism includes a motor installed at the end of the conveying frame, a first pulley fixed at one end of each conveying roller, a second pulley fixed at the driving end of the motor, and each adjacent first pulley and the second pulley and a first pulley at the end are connected by a synchronous belt drive.

[0018] The present invention provides a pipe body deviation correction device for glass fiber reinforced plastic pipe production by improvement, which has the following improvements and advantages compared with the prior art: First, the present invention drives multiple conveying rollers to rotate synchronously through a driving mechanism, thereby conveying the FRP tube, and senses the offset direction of the FRP tube through a centering ring located at both ends of each conveying roller. When the FRP tube deviates to either side to a certain extent, the centering ring drives the sliding column in the airflow guide mechanism to move through the transmission mechanism, thereby changing the direction of the airflow, so that the airflow flows to the inner side of a piston cylinder located in the offset direction, thereby pushing the corresponding side rollers close to the outer side of the FRP tube, pushing the FRP tube to reset to the center, thereby correcting the offset. Compared with the prior art, there is no need to apply clamping force to both sides of the FRP tube in real time by setting multiple rollers on both sides, which not only reduces the transmission resistance of the FRP tube, avoids slippage between the conveying roller and the FRP tube and increases the wear on the outer side of the FRP tube, but also reduces the extrusion force on both sides of the FRP tube, thereby better avoiding the probability of deformation of the FRP tube during the transmission process, and ensuring the roundness of the FRP tube in production and transmission.

[0019] Secondly, the present invention arranges a centering spring on one side of the two inner slides, so that the two inner slides can be elastically connected to the inner ends of the conveying roller, thereby making the two centering rings elastically connected to the two ends of the conveying roller. When the FRP tube undergoes a small lateral offset, a centering spring located at one end of the offset direction will be compressed, thereby applying a reaction force to an inner slide at the corresponding position, thereby forcing the two inner slides to return to the middle position, thereby driving the two centering rings to return to the middle position of the conveying roller. The two centering rings drive the FRP tube to return to the middle position, which automatically corrects the offset, thereby reducing the lateral offset amplitude of the FRP tube. When the FRP tube undergoes a slight offset, the FRP tube is corrected only by the centering rings on both sides, without the need to correct the offset by the side rollers, thereby reducing the number of times the side rollers squeeze the outer side of the FRP tube, thereby further preventing the deformation and wear of the FRP tube.

[0020] Thirdly, the present invention arranges a centering ring and a rubber ring on the outer side of the conveying roller. When the FRP pipe is conveyed, the rubber ring can be used to support the FRP pipe. The FRP pipe does not contact the outer surface of the conveying roller. Supporting the FRP pipe by two rubber rings can not only increase the contact area, but also the rubber ring is soft in texture and will not cause local squeezing on the outer side of the FRP pipe, thereby avoiding stress concentration on the outer side of the FRP pipe, thereby further reducing the probability of deformation of the FRP pipe during transportation.

[0024] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. 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.

[0025] The present invention provides a pipe body deviation correction device for glass fiber reinforced plastic pipe production through improvement. The technical solution of the present invention is: like Figures 1 to 8As shown, an embodiment of the present invention provides a pipe body correction device for glass fiber reinforced plastic pipe production, including a conveying frame 1 and a plurality of conveying rollers 2, each of which is rotatably mounted on the upper side of the conveying frame 1 through a bracket 3, and also includes: a centering correction mechanism arranged at the position of each conveying roller 2; a driving mechanism that drives the plurality of conveying rollers 2 to rotate synchronously; the centering correction mechanism includes two piston cylinders 101 fixed on both sides of the conveying frame 1 through a column 106, two telescopic rods 102 slidably inserted at one end of the two piston cylinders 101, two side rollers 103 arranged at one end of the two telescopic rods 102, and an airflow guide mechanism for introducing compressed air to the two piston cylinders 101 according to the deviation direction of the glass fiber reinforced plastic pipe; the airflow guide mechanism includes an air guide cylinder 201, two centering rings 4 slidably sleeved on the outer side of the conveying roller 2, a sliding column 203 is slidably arranged on the inner side of the air guide cylinder 201, and an outer side of the sliding column 203 Two annular grooves 204 are provided on the side, and the air cylinder 201 is communicated with the inner sides of the two piston cylinders 101 respectively through two air outlet pipes 206, and the air cylinder 201 is connected to the air source device through the air inlet pipe 205. Two air outlet holes 208 for plugging the air outlet pipes 206 are provided on the outside of the air cylinder 201, and an air inlet hole 207 for plugging the air inlet pipe 205 is also provided on the outside of the air cylinder 201. The air source device includes an air pump 8 and an air tank 7 connected to one end of the air inlet pipe 205. The air outlet end of the air pump 8 is connected to the inside of the air tank 7. The two centering rings 4 drive the sliding column 203 to reciprocate through a transmission mechanism; the transmission mechanism includes a sliding rod 2 302 fixed to the two centering rings 4, a steering rod 305 rotatably arranged at one end of the bracket 3, and a sliding rod 1 309 fixed to the sliding column 203. The two ends of the steering rod 305 are movably connected to the sliding rod 1 309 and one end of the sliding rod 2 302 respectively.

[0026] Further, the transmission mechanism also includes two inner slide plates 301 slidably connected to the inner side of the conveying roller 2, a second slide bar 302 is fixed through the inside of the two inner slide plates 301, a steering rod 305 is rotatably connected to one end of the bracket 3 through an extension frame 304, the outer sides of the two inner slide plates 301 are respectively fixed to the inner sides of the two centering rings 4 through a plurality of connecting blocks, two sliding pin grooves 308 are provided at both ends of the steering rod 305, one end of the second slide bar 302 is rotatably connected to a rotating column 307, one end of the rotating column 307 is rotatably connected to a second sliding pin 306 that is rollingly adapted to the inner side of the sliding pin groove 308 at a corresponding position, one end of the first slide bar 309 is rotatably connected to a first sliding pin 303 that is rollingly adapted to the inner side of another sliding pin groove 308, and the first slide bar 309 is fixed through the inside of the slide column 203; When the FRP pipe is offset, it will drive the two centering rings 4 to move toward one end. The two centering rings 4 will drive the sliding column 203 in the airflow guide mechanism to move through the transmission mechanism, thereby changing the direction of the airflow, so that the airflow flows to the inner side of a piston cylinder 101 located in the offset direction, thereby pushing the corresponding side roller 103 close to the outside of the FRP pipe, pushing the FRP pipe to return to the center, thereby correcting the offset.

[0027] Furthermore, one side of the inner slide plate 301 is elastically connected to both ends of the inner side of the conveying roller 2 through the centering spring 9; When the FRP tube is subjected to lateral force during transmission, it will push the two centering rings 4 to move a small distance to either end. At this time, the FRP tube will have a small lateral offset. At this time, a centering spring 9 located at one end of the offset direction will be compressed, thereby applying a reaction force to an inner slide 301 at the corresponding position, thereby forcing the two inner slides 301 to return to the middle position, thereby driving the two centering rings 4 to return to the middle position of the conveying roller 2. The two centering rings 4 drive the FRP tube to return to the middle position, thereby automatically correcting the offset.

[0028] Furthermore, the two side rollers 103 are rotatably mounted on one end of the two telescopic rods 102 through the roller frame 104, and one end of the two telescopic rods 102 is fixed with a piston plate slidably connected to the inner side of the piston cylinder 101. One side of the two roller frames 104 is fixed with a guide rod 105, and each guide rod 105 is slidably inserted into the inside of the column 106 at the corresponding position. The outer sides of the two piston cylinders 101 are provided with a plurality of damping exhaust holes 107 near one end of the roller frame 104; The guide rod 105 can make the roller frame 104 and the side roller 103 move along a straight line, so that the side roller 103 can apply a lateral thrust to the FRP tube to assist the FRP tube to be centered. When the compressed air enters the inner side of the piston cylinder 101 through the multiple damping exhaust holes 107, it will push the piston plate to move toward one end of the piston cylinder 101, and discharge the air at the other end of the inner side of the piston cylinder 101 through the multiple damping exhaust holes 107. In the process of air being discharged through the damping exhaust holes 107, a certain resistance can be provided to the piston plate, so that the piston plate and the telescopic rod 102 can be stably extended, and their extension speed can be slowed down, thereby avoiding driving the side roller 103 to hit the outer side of the FRP tube, thereby preventing the FRP tube from being deformed due to the impact.

[0029] Furthermore, two through holes 210 (such as Figure 7 As shown), a plurality of exhaust notches 209 are provided at both ends of the air guide cylinder 201 near both ends of the sliding column 203, and one side of the two piston plates is elastically connected to the inner ends of the two piston cylinders 101 through the return springs 108; After the deviation-correcting mechanism has centered the offset FRP tube, when the FRP tube returns to the middle position, it pushes the two centering rings 4 to return to the middle position of the conveying roller 2, thereby driving the slide column 203 to return to the middle position of the air guide cylinder 201. At this time, the middle position of the slide column 203 blocks the air inlet 207. At this time, the air inside the gas tank 7 no longer enters the inner side of the air guide cylinder 201. Under the elastic force of the return spring 108 at the left end, the telescopic rod 102 and the piston plate at the left end are pushed to move left and reset. When the piston plate moves left and resets, the air inside the piston cylinder 101 is pressed into the inner side of the annular groove 204 at the left end, and then discharged to the outside through the multiple exhaust notches 209 at the left end, thereby achieving the correction of the deviation of the FRP tube.

[0030] Furthermore, the driving mechanism includes a motor 401 installed at the end of the conveying frame 1, a first pulley 402 fixed to one end of each conveying roller 2, a second pulley 403 is fixed to the driving end of the motor 401, and each adjacent first pulley 402 and the second pulley 403 and a first pulley 402 at the end are connected by a synchronous belt 404; The driving mechanism is used to drive each conveying roller 2 to rotate synchronously, thereby conveying the glass fiber reinforced plastic pipe.

[0031] Working principle: when the device is running, the motor 401 of the driving mechanism is controlled to run, and the motor 401 drives the second pulley 403 to rotate. The second pulley 403 drives a first pulley 402 at the end to rotate through the synchronous belt 404. The first pulley 402 at this end drives an adjacent first pulley 402 to rotate synchronously through the synchronous belt 404, and so on, thereby driving each first pulley 402 to rotate at an equal speed, and each first pulley 402 drives the corresponding conveying roller 2 to rotate at a constant speed. When each conveying roller 2 rotates, it can apply thrust to the connecting block through the guide groove 5, thereby driving the opposite ends of the outer side of each guide groove 5. The center ring 4 rotates synchronously, and a rubber ring 6 is arranged on the outer side of each center ring 4, so that multiple rubber rings 6 can be driven to rotate synchronously, and the glass fiber reinforced plastic pipe to be transported is placed above multiple transport rollers 2. Since the outer side of the rubber ring 6 is higher than the outer side of the transport roller 2, the glass fiber reinforced plastic pipe can be supported by the rubber ring 6, and the glass fiber reinforced plastic pipe does not contact the outer surface of the transport roller 2. The glass fiber reinforced plastic pipe is supported by two rubber rings 6, which not only increases the contact area, but also the rubber ring 6 is soft in texture, so it will not cause local extrusion on the outer side of the glass fiber reinforced plastic pipe, avoiding stress concentration on the outer side of the glass fiber reinforced plastic pipe, thereby reducing the probability of deformation of the glass fiber reinforced plastic pipe during transportation; Since one side of the two inner slide plates 301 is elastically connected to the inner ends of the conveying roller 2 through the centering springs 9, the two centering rings 4 can also be elastically connected to the two ends of the conveying roller 2. It should be noted that when the two inner slide plates 301 are located at the middle section of the conveying roller 2, the two centering springs 9 are just not compressed. When the glass fiber reinforced plastic pipe is subjected to lateral force during transmission, the two centering rings 4 will be pushed to move a small distance to either end. At this time, the glass fiber reinforced plastic pipe will have a small lateral deviation. At this time, a centering spring 9 located at one end of the deviation direction will be compressed, thereby applying a reaction force to an inner slide plate 301 at the corresponding position, thereby forcing the two inner slide plates 301 to return to the middle section position, so that the two rubber rings 6 can be driven to return to the middle section of the conveying roller 2. The two rubber rings 6 drive the glass fiber reinforced plastic pipe to return to the middle position, which plays a role in automatically correcting the deviation, thereby reducing the lateral deviation amplitude of the glass fiber reinforced plastic pipe. If the lateral deviation of the glass fiber reinforced plastic pipe is too large, the glass fiber reinforced plastic pipe cannot be corrected under the action of the two centering springs 9, and the two rubber rings 6 drive the two inner slide plates 301 to move on the inner side of the conveying roller 2 through the centering ring 4, and the two inner slide plates 301 drive the second slide bar 302 to move, and the second slide bar 302 drives the second slide pin 306 to move through the rotating column 307 at one end, and the rolling cooperation between the second slide pin 306 and the slide pin groove 308 can drive the steering rod 305 to rotate a certain angle, and the other end of the steering rod 305 is connected to the slide pin 303 through the first slide pin 303. The rolling cooperation between the pin grooves 308 drives the slide bar 1 309 to move in the opposite direction to the slide bar 2 302, and the slide bar 1 309 drives the slide column 203 of the air flow guide mechanism to move inside the air guide cylinder 201, and the slide column 203 drives the two annular grooves 204 on its outer side to move. When the slide column 203 reaches a certain movement stroke, the air inlet 207 and one of the air outlets 208 are connected to one of the annular grooves 204 at the same time, and the air pump 8 of the air source device is operated to fill the compressed air into the inside of the air tank 7, so that the compressed air inside the air tank 7 is maintained at a certain pressure; like Figure 4 As shown, if the glass fiber reinforced plastic pipe deviates to the left side of the conveying frame 1, the two inner slide plates 301 are driven to move to the left end of the conveying roller 2, thereby driving the slide column 203 to move to the right end of the air guide cylinder 201 through the transmission mechanism, as shown in FIG. Figure 8As shown, at this time, the air inlet 207 and an air outlet 208 at the left end are simultaneously connected to an annular groove 204 at the left end, so that the air inlet pipe 205 and the air outlet pipe 206 at the left end are simultaneously connected to an annular groove 204 at the left end. At this time, the compressed air inside the gas tank 7 in the gas source device flows into the inner side of the annular groove 204 at the left end through the air inlet pipe 205. At this time, the left end of the sliding column 203 blocks the exhaust notch 209 at the left end. Therefore, the air flowing into the inner side of the annular groove 204 at the left end will not be discharged to the outside, but will flow into the inner side of the air outlet pipe 206 at the left end through the air outlet 208 at the left end, and finally flow into one end of the inner side of a piston cylinder 101 at the left end through this air outlet pipe 206, thereby pushing a piston plate at the left end, and the piston plate drives a telescopic rod 102 at the left end to extend, and the telescopic rod 102 at the left end drives the side roller 103 at the left end to move close to the offset glass fiber reinforced plastic pipe, so that the glass fiber reinforced plastic pipe returns to the middle position; When the glass fiber reinforced plastic tube returns to the middle position, it drives the two centering rings 4 to return to the middle position of the conveying roller 2, thereby driving the sliding column 203 to return to the middle position of the air guide cylinder 201. At this time, the middle position of the sliding column 203 blocks the air inlet hole 207. At this time, the air inside the gas tank 7 no longer enters the inner side of the air guide cylinder 201, so the telescopic rod 102 at the left end no longer extends. At the same time, under the elastic force of the reset spring 108, the telescopic rod 102 at the left end and the piston plate are pushed to move left and reset, thereby driving the side roller 103 to reset. At the same time, when the piston plate moves left and resets, the air inside the piston cylinder 101 is pushed out. The air outlet pipe 206 at the left end is pressed into the inner side of the annular groove 204 at the left end, and then discharged to the outside through the multiple exhaust notches 209 at the left end, thereby realizing the correction of the deviation of the FRP pipe. Compared with the prior art, this method can correct the deviation of the FRP pipe in transmission without applying clamping force to both sides of the FRP pipe in real time through multiple rollers on both sides, which not only reduces the transmission resistance of the FRP pipe, but also reduces the extrusion force on both sides of the FRP pipe, thereby better avoiding the probability of deformation of the FRP pipe during transmission and ensuring the roundness of the FRP pipe during production and transmission.

[0032] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
