A pipe body rectifying device for the production of glass steel pipes

Abstract

The present invention relates to the technical field of fiberglass pipe production, and particularly to a pipe body alignment device for fiberglass pipe production, which includes a conveying frame and a plurality of conveying rollers. Each of the conveying rollers is rotatably installed on the upper side of the conveying frame through a bracket, and further includes: a centering and alignment mechanism provided at each position of the conveying rollers; a driving mechanism for driving the plurality of conveying rollers to rotate synchronously. By means of the alignment mechanism, the fiberglass pipe being conveyed is centered, without the need to apply a clamping force to both sides of the fiberglass pipe in real time by arranging a plurality of rollers on both sides. This not only reduces the conveying resistance of the fiberglass pipe, avoids slippage between the conveying rollers and the fiberglass pipe and increases the wear on the outer side of the fiberglass pipe, but also can reduce the extrusion force on both sides of the fiberglass pipe, thereby better avoiding the probability of deformation of the fiberglass pipe during the conveying process and ensuring the roundness of the fiberglass pipe during production and conveying.

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.

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

[0014] Preferably, one side of each of the two piston plates is elastically connected to one end of the inner side of each of the two piston cylinders through a return spring respectively.

[0018] The present invention provides a pipe body deviation rectifying device for fiberglass pipe production through improvement. Compared with the prior art, it has the following improvements and advantages:

[0019] First: The present invention drives a plurality of conveying rollers to rotate synchronously through the driving mechanism, so as to convey the fiberglass pipe. And the deviation direction of the fiberglass pipe is sensed by the centering rings located at both ends of each conveying roller. When the fiberglass pipe deviates to either side by a certain amplitude, the centering rings drive the sliding column in the air flow guiding mechanism to move through the transmission mechanism, so as to change the air flow direction, make the air flow flow into the inner side of one piston cylinder located in the deviation direction, thereby pushing the corresponding side roller close to the outer side of the fiberglass pipe and pushing the fiberglass pipe to reset to the center, thus playing a role in correcting the deviation. Compared with the prior art, there is no need to apply clamping forces to both sides of the fiberglass pipe in real time by arranging a plurality of rollers on both sides, which not only reduces the conveying resistance of the fiberglass pipe, avoids slipping between the conveying rollers and the fiberglass pipe and increases the wear on the outer side of the fiberglass pipe, but also can reduce the extrusion forces on both sides of the fiberglass pipe, so that the probability of deformation of the fiberglass pipe during conveying can be better avoided, and the roundness during the production and conveying of the fiberglass pipe is ensured.

[0020] Second: By providing centering springs on one side of the two inner sliding plates, the two inner sliding plates can be elastically connected to the inner ends of both sides of the conveying roller, so that the two centering rings are elastically connected to the two ends of the conveying roller. When the glass steel pipe has a small lateral offset, one centering spring at the end in the offset direction will be compressed, thereby applying a reaction force to one inner sliding plate at the corresponding position, forcing the two inner sliding plates to return to the middle position. Therefore, it can drive the two centering rings to also return to the middle position of the conveying roller, and the two centering rings drive the glass steel pipe to return to the middle position, playing a role in automatically correcting the offset, thereby reducing the lateral offset amplitude of the glass steel pipe. When the glass steel pipe has a slight offset, only the centering rings on both sides are used to correct the deviation of the glass steel pipe, without using side rollers to correct the deviation of the glass steel pipe, reducing the number of times the side rollers squeeze the outer side of the glass steel pipe, thereby further preventing the deformation and wear of the glass steel pipe.

[0021] Third: By providing centering rings and rubber rings on the outer side of the conveying roller, when the glass steel pipe is conveyed, the rubber rings can support the glass steel pipe, and the glass steel pipe does not contact the outer surface of the conveying roller. The glass steel pipe is supported by two rubber rings, which can not only increase the contact area, but also the texture of the rubber rings is soft, so it will not cause local extrusion to the outer side of the glass steel pipe, avoiding stress concentration on the outer side of the glass steel pipe, thereby further reducing the probability of deformation of the glass steel pipe during transportation.

Detailed implementation mode

[0033] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0034] The present invention provides a pipe body deviation rectifying device for the production of glass steel pipes by improvement. The technical solution of the present invention is:

[0035] Such as Figures 1 to 8As shown in the figure, an embodiment of the present invention provides a pipe body alignment device for the production of fiberglass pipes, including a conveying frame 1 and a plurality of conveying rollers 2. Each conveying roller 2 is rotatably installed on the upper side of the conveying frame 1 through a bracket 3, and further includes: a centering and alignment mechanism provided at each position of the conveying roller 2; a driving mechanism for driving the plurality of conveying rollers 2 to rotate synchronously; the centering and alignment mechanism includes two piston cylinders 101 fixed to both sides of the conveying frame 1 through columns 106, two telescopic rods 102 slidably inserted into one end of the two piston cylinders 101, two side rollers 103 provided at one end of the two telescopic rods 102, and an air flow guiding mechanism for respectively introducing compressed air into the two piston cylinders 101 according to the offset direction of the fiberglass pipe; the air flow guiding mechanism includes a gas guiding cylinder 201, two centering rings 4 slidably sleeved outside the conveying roller 2. A sliding column 203 is slidably arranged inside the gas guiding cylinder 201. Two annular grooves 204 are opened on the outer side of the sliding column 203. The gas guiding cylinder 201 is respectively communicated with the inner sides of the two piston cylinders 101 through two air outlet pipes 206, and the gas guiding cylinder 201 is connected with a gas source device through an air inlet pipe 205. Two air outlet holes 208 for inserting the air outlet pipes 206 are opened on the outer side of the gas guiding cylinder 201, and an air inlet hole 207 for inserting the air inlet pipe 205 is further opened on the outer side of the gas guiding cylinder 201. The gas source device includes an air pump 8 and an air tank 7 communicated with one end of the air inlet pipe 205. The air outlet end of the air pump 8 is communicated with 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 second sliding rod 302 fixed to the two centering rings 4, a steering rod 305 rotatably arranged at one end of the bracket 3, and a first sliding rod 309 fixed to the sliding column 203. The two ends of the steering rod 305 are respectively movably connected with one end of the first sliding rod 309 and the second sliding rod 302.

[0036] Further, the transmission mechanism further includes two inner sliding plates 301 slidably connected inside the conveying roller 2. The second sliding rod 302 penetrates and is fixed inside the two inner sliding plates 301. The 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 sliding 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 opened at the two ends of the steering rod 305. One end of the second sliding rod 302 is rotatably connected with a rotating column 307. One end of the rotating column 307 is rotatably connected with a second sliding pin 306 that is rollingly adapted to the inner side of the corresponding sliding pin groove 308. One end of the first sliding rod 309 is rotatably connected with a first sliding pin 303 that is rollingly adapted to the inner side of the other sliding pin groove 308. The first sliding rod 309 penetrates and is fixed inside the sliding column 203;

[0037] When the glass steel pipe is offset, it will drive the two centering rings 4 to move towards one end. The two centering rings 4 drive the sliding column 203 in the air flow guiding mechanism through a transmission mechanism, thereby changing the flow direction of the air flow, making the air flow flow towards the inside of a piston cylinder 101 located in the offset direction, thereby pushing the corresponding side roller 103 close to the outside of the glass steel pipe and pushing the glass steel pipe back to the centered position, thus playing a role in correcting the offset.

[0038] Further, one side of each inner sliding plate 301 is elastically connected to both inner ends of the conveying roller 2 through centering springs 9 respectively;

[0039] When the glass steel pipe is subjected to a lateral force during transmission, it will push the two centering rings 4 to move a small distance towards any one end. At this time, the glass steel pipe has a small lateral offset. At this time, a centering spring 9 at one end located in the offset direction will be compressed, thereby exerting a reaction force on an inner sliding plate 301 at the corresponding position, thereby forcing the two inner sliding plates 301 to return to the middle position. Therefore, it can drive the two centering rings 4 to also return to the middle position of the conveying roller 2, and the two centering rings 4 drive the glass steel pipe to return to the middle position, playing a role in automatically correcting the offset.

[0040] Further, both side rollers 103 are respectively rotatably installed at one end of two telescopic rods 102 through roller frames 104. A piston plate slidably connected to the inside of the piston cylinder 101 is fixed at one end of each of the two telescopic rods 102. A guide rod 105 is fixed to one side of each of the two roller frames 104. Each guide rod 105 is slidably inserted into the inside of a corresponding column 106. A plurality of damping exhaust holes 107 are opened at one end of the outside of each of the two piston cylinders 101 close to the roller frame 104;

[0041] 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 exert a lateral thrust on the glass steel pipe to assist the glass steel pipe to be centered. Through the plurality of damping exhaust holes 107, when compressed air enters the inside of the piston cylinder 101, it will push the piston plate towards one end of the piston cylinder 101, and discharge the air at the other end inside the piston cylinder 101 through the plurality of damping exhaust holes 107. During the process of the air discharging 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 stably extend and slow down their extending speed, thereby avoiding driving the side roller 103 to impact the outside of the glass steel pipe, and thus avoiding the glass steel pipe from being deformed due to impact.

[0042] Further, two through holes 210 are opened at both ends of the air guide cylinder 201 (as Figure 7 shown), and a plurality of exhaust slots 209 are opened at both ends of the air guide cylinder 201 close to both ends of the sliding column 203. One side of each of the two piston plates is elastically connected to one end inside each of the two piston cylinders 101 through a return spring 108 respectively;

[0043] 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.

[0044] 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;

[0045] The driving mechanism is used to drive each conveying roller 2 to rotate synchronously, thereby conveying the glass fiber reinforced plastic pipe.

[0046] 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;

[0047] Since one side of each of the two inner sliding plates 301 is elastically connected to the inner ends of both sides of the conveying roller 2 through centering springs 9 respectively, 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 sliding plates 301 are located at the middle position of the conveying roller 2, the two centering springs 9 are just not compressed. When the glass steel pipe is conveyed and subjected to a lateral force, it will push the two centering rings 4 to move a small distance to any one end. At this time, the glass steel pipe has a small lateral offset. At this time, one centering spring 9 at one end in the offset direction will be compressed, so as to exert a reaction force on one inner sliding plate 301 at the corresponding position, thus forcing the two inner sliding plates 301 to return to the middle position. Therefore, the two rubber rings 6 can be driven to also return to the middle position of the conveying roller 2, and the two rubber rings 6 drive the glass steel pipe to return to the middle position, playing a role in automatically correcting the offset, thereby reducing the lateral offset amplitude of the glass steel pipe;

[0048] If the lateral offset amplitude of the glass steel pipe is too large and the glass steel pipe cannot be rectified under the action of the two centering springs 9, the two rubber rings 6 drive the two inner sliding plates 301 to move inside the conveying roller 2 through the centering rings 4. The two inner sliding plates 301 drive the second sliding rod 302 to move. The second sliding rod 302 drives the second sliding pin 306 to move through the rotating column 307 at one end. Through the rolling cooperation between the second sliding pin 306 and the sliding pin groove 308, the steering rod 305 can be driven to rotate a certain angle. The other end of the steering rod 305 drives the first sliding rod 309 to move in the opposite direction to the second sliding rod 302 through the rolling cooperation between the first sliding pin 303 and the sliding pin groove 308. The first sliding rod 309 drives the sliding column 203 of the air flow guiding mechanism to move inside the air guiding cylinder 201. The sliding column 203 drives the two annular grooves 204 on its outer side. When the sliding column 203 reaches a certain moving stroke, the air inlet hole 207 and one of the air outlet holes 208 will be simultaneously communicated with one of the annular grooves 204. At the same time, the air pump 8 of the air source device operates to fill compressed air into the air tank 7, so that the inside of the air tank 7 maintains compressed air with a certain pressure;

[0049] As Figure 4 shown, if the glass steel pipe offsets to the left side of the conveying frame 1, it drives the two inner sliding plates 301 to move to the left end of the conveying roller 2, thereby driving the sliding column 203 to move to the right end of the air guiding cylinder 201 through the transmission mechanism. As Figure 8As shown, at this time, the intake hole 207 and one of the outlet holes 208 at the left end are simultaneously communicated with one of the annular grooves 204 at the left end, so that the intake pipe 205 and the outlet pipe 206 at the left end are simultaneously communicated with one of the annular grooves 204 at the left end. At this time, the compressed air inside the air tank 7 in the air source device flows into the inner side of the annular groove 204 at the left end through the intake pipe 205. At this time, the left end of the sliding column 203 blocks the exhaust slot 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 flows into the inner side of the outlet pipe 206 at the left end through the outlet hole 208 at the left end, and finally flows into one end of the inner side of the piston cylinder 101 at the left end through this outlet pipe 206, thereby pushing a piston plate at the left end. 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 closer to the offset glass steel pipe, so that the glass steel pipe returns to the middle position;

[0050] When the glass steel pipe returns to the middle position, it drives the two centering rings 4 to also 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 intake hole 207. At this time, the air inside the air tank 7 no longer enters the inner side of the air guide cylinder 201. Therefore, the telescopic rod 102 at the left end no longer extends. At the same time, under the elastic force of the return spring 108, it will also push the telescopic rod 102 and the piston plate at the left end to move leftward to reset, thereby driving the side roller 103 to reset. At the same time, when the piston plate moves leftward to reset, the air inside the piston cylinder 101 is pressed into the inner side of the annular groove 204 at the left end through the outlet pipe 206 at the left end, and is discharged to the outside through the multiple exhaust slots 209 at the left end, thereby realizing the function of correcting the offset of the glass steel pipe. Compared with the prior art, by correcting the offset of the glass steel pipe in this way, there is no need to apply clamping forces to both sides of the glass steel pipe in real time through multiple rollers on both sides, which not only reduces the conveying resistance of the glass steel pipe, but also can reduce the extrusion force received by both sides of the glass steel pipe, thereby better avoiding the probability of deformation of the glass steel pipe during conveying and ensuring the roundness of the glass steel pipe during production and conveying.

The general principles defined herein can 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 these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
