[0018] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] See also Figure 1 and Figure 2As shown, according to an embodiment of the present invention, a grinding device for the inner and outer layers of a fiberglass reinforced plastic (FRP) pipe is provided, comprising: two outer rings 1 and two inner rings 2, the two outer rings 1 being symmetrically arranged, and the inner rings 2 being disposed within the corresponding outer rings 1, and a support mechanism 3 being provided between the outer rings 1 and the corresponding inner rings 2 for supporting the inner rings 2. Several grinding plates 4 are divided into two groups and fixedly installed at equal intervals between two outer rings 1 and two inner rings 2; Several rollers 7 are evenly spaced between two outer rings 1, and a limiting plate 8 is provided above them. A soft ring 9 is fixedly sleeved on the outer periphery of the rollers 7. The driving component 5 is provided on the outer periphery of the roller 7 and is used to drive the roller 7 to rotate. Adjusting element 6, which is located between roller 7 and limiting plate 8, is used to adjust the angle of roller 7.

[0020] In this embodiment, when the improved fiberglass reinforced plastic (FRP) sand-filled pipe inner and outer layer grinding device is used, the existing double roller drive conveyor is used to sequentially push the FRP sand-filled pipe to move along a fixed trajectory. Please refer to Figure 1 and Figure 2 As shown, (one outer ring 1 and inner ring 2 form an inlet 11, and the other outer ring 1 and inner ring 2 form an outlet 12), firstly, the adjusting component 6 starts the drive roller 7 to rotate 90 degrees in the forward direction, so that the outer peripheral wall of the roller 7 is aligned with the moving part. At the same time, the driving component 5 starts the drive roller 7 to rotate at a constant speed. Then, the roller drive feeder pushes the fiberglass reinforced sand tube into the inlet 11. Due to the mutual contact between the end of the fiberglass reinforced sand tube and the support mechanism 3, the support mechanism 3 at the inlet 11 position releases the support limit state of the inner ring 2. And since the fiberglass reinforced sand tube is sleeved on the inner ring 2, the position of the inner ring 2 remains unchanged (during the process of the fiberglass reinforced sand tube being inserted between the grinding plates 4, the support mechanism 3 at the outlet 12 position still maintains the constraint limit of the two inner rings 2 and the grinding plates 4 between the two inner rings 2, so as to avoid the inner ring 2 and outer ring 1 shifting due to the friction between the fiberglass reinforced sand tube and the grinding plates 4 during the process of the fiberglass reinforced sand tube being inserted between the grinding plates 4, which would affect the use of the device). When the end of the fiberglass reinforced plastic (FRP) sand-filled pipe moves to the position of roller 7, due to the mutual contact between the end of the FRP sand-filled pipe and the soft ring 9, and with the rotation of roller 7, the soft ring 9 contracts and deforms at the contact point with the FRP sand-filled pipe, so that a frictional force of corresponding strength is generated between roller 7 and the outer peripheral wall of the FRP sand-filled pipe. At this time, the rotating roller 7 can push the FRP sand-filled pipe towards the discharge port 12. The rotating roller 7, together with the roller-driven conveyor, pushes the FRP sand-filled pipe between the grinding plates 4. (An infrared distance sensor can be used to detect whether the FRP sand-filled pipe has moved to the required position, and the whole device is automatically controlled by an external controller). After the FRP sand-filled pipe moves out of the inlet 11, the support mechanism 3 automatically completes the support of the inner ring 2 again. After the fiberglass reinforced sand tube is moved between several grinding plates 4, the adjusting component 6 drives the roller 7 to rotate 90 degrees in the opposite direction, and then the driving component 5 drives the roller 7 to rotate at a constant speed, thereby driving the fiberglass reinforced sand tube to rotate between several grinding plates 4, so as to complete the grinding operation of the inner and outer layers of the fiberglass reinforced sand tube through the mutual friction between the grinding plates 4 and the inner and outer sides of the fiberglass reinforced sand tube. After the inner and outer layers of the fiberglass reinforced plastic (FRP) pipe are polished, the drive unit 5 drives the roller 7 to rotate 90 degrees in the forward direction. The drive unit 5 continues to drive the roller 7 to rotate, thereby pushing the FRP pipe out of the outlet 12. The polished FRP pipe is then transported to the corresponding position by the existing roller-driven conveyor. After the FRP pipe is moved out of the outlet 12, the roller-driven conveyor pushes the next FRP pipe into the inlet 11. This process is repeated to complete the polishing operation of the inner and outer sides of several FRP pipes. It should be noted that, as described above, during the process of inserting the end of the fiberglass reinforced sand pipe into the outlet 12, due to the mutual contact between the end of the fiberglass reinforced sand pipe and the support mechanism 3, the support mechanism 3 at the outlet 12 automatically releases the support limit of the inner ring 2, and due to the constraint limit of the support mechanism 3 at the inlet 11 on the two inner rings 2 and the grinding plate 4, the two inner rings 2 and the grinding plate 4 will not have positional deviations that affect the use of the device. In summary, when this improved fiberglass reinforced plastic (FRP) pipe inner and outer layer grinding device is used, the grinding plate 4 and the roller 7 can work together to complete the grinding operations of several FRP pipe inner and outer layers in sequence. It also avoids the reciprocating loading and unloading operation of FRP pipes. The device has a high degree of automation, which greatly reduces the time required for grinding the inner and outer layers of FRP pipes and improves the grinding efficiency of the inner and outer sides of FRP pipes.

[0021] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 3As shown, the inner diameter of the outer ring 1 is greater than the distance between the opposite sides of the two corresponding grinding plates 4, and the outer diameter of the inner ring 2 is less than the distance between the opposite sides of the two corresponding grinding plates 4. The corners at both ends of the grinding plates 4 are set in an arc shape. In this embodiment, please refer to Figure 1 and Figure 3 As shown, the distance between the outer ring 1 and the inner ring 2 wall and the inner ring 2 and outer ring 1 wall is greater than the distance between the corresponding two grinding plates 4. This is to prevent the burrs on the fiberglass reinforced pipe from colliding with the outer ring 1 or the inner ring 2, which would affect the insertion of the fiberglass reinforced pipe between several grinding plates 4. In addition, the arc-shaped design of the two ends of the grinding plate 4 prevents the two ends of the grinding plate 4 from colliding with the fiberglass reinforced pipe, which would also affect the insertion of the fiberglass reinforced pipe between several grinding plates 4. It should be noted that, please refer to Figure 1 and Figure 3 As shown, two support rollers are symmetrically rotatable between the two outer rings 1, which are used to support the fiberglass reinforced plastic (FRP) sand-filled tube in conjunction with the roller 7, so as to avoid the FRP sand-filled tube from shifting downward due to the pressure of the roller 7 on the FRP sand-filled tube, which would affect the grinding effect of the inner and outer layers of the FRP sand-filled tube. Please refer to Figure 1 As shown, bases are fixedly installed on the bottom sides of the two outer rings 1 for supporting the entire device.

[0022] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 2 As shown, both ends of the limiting plate 8 are fixedly equipped with electrically controlled telescopic rods 10, and the driving end of the electrically controlled telescopic rod 10 passes through the limiting plate 8 and is fixedly connected to the corresponding outer ring 1. In this embodiment, please refer to Figure 1 and Figure 2 As shown, the electric telescopic rod 10 allows the height of the limiting plate 8 to be adaptively adjusted according to the wear of the soft ring 9, so as to avoid the wear of the soft ring 9 causing a decrease in the contact force between the roller 7 and the fiberglass reinforced pipe, thereby reducing the friction between the fiberglass reinforced pipe and the roller 7 and thus affecting the operation of the device.

[0023] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the support mechanism 3 includes several limiting grooves 31, which are equally spaced on the outer peripheral wall of the corresponding inner ring 2. A storage groove 32 is provided on the inner wall of the outer ring 1 at the position corresponding to the limiting groove 31. A limiting block 33 is slidably installed in the storage groove 32, and both sides of one end of the limiting block 33 are inclined and inserted into the corresponding limiting groove 31. A spring 34 is provided in the storage groove 32, and the two ends of the spring 34 are fixedly connected to the other end of the corresponding limiting block 33 and the inner wall of the corresponding storage groove 32, respectively. In this embodiment, please refer to Figure 1 , Figure 4 and Figure 5 As shown, when the end of the fiberglass reinforced sand tube is pushed into the inlet 11 or outlet 12, the limiting block 33 can be squeezed into the storage tank 32 by the mutual contact between the end of the fiberglass reinforced sand tube and the inclined surface of the limiting block 33. (It should be noted that a ball bearing can also be installed on the limiting block 33 to replace the limiting block 33 and insert it into the limiting groove 31, so that the fiberglass reinforced sand tube can be squeezed and pushed by the limiting block 33 more easily). After the limiting block 33 is squeezed into the storage tank 32, the fiberglass reinforced sand tube can directly pass through the gap between the outer ring 1 and the inner ring 2, so that the fiberglass reinforced sand tube can be directly pushed between several grinding plates 4, or the fiberglass reinforced sand tube can be pushed out between several grinding rods. After the fiberglass reinforced plastic (FRP) sand-filled pipe is removed from the inlet 11 or outlet 12, due to the push of the spring 34 on the limiting block 33, the limiting block 33, which is retracted into the storage tank 32, extends directly from the storage tank 32 and inserts into the limiting groove 31. Thus, through the mutual contact between the limiting block 33 and the inner wall of the limiting groove 31, the inner ring 2 is supported by multiple directions, so that the inner ring 2 is always located at the center of the outer ring 1.

[0024] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the driving component 5 includes a mounting base 51, which is rotatably sleeved on the outer periphery of the corresponding roller 7. A motor 52 is fixedly mounted on the outer wall of the mounting base 51, and the driving end of the motor 52 is fixedly connected to the corresponding roller 7. In this embodiment, please refer to Figure 2 and Figure 4 As described above, during the use of the device, the external control system controls several motors 52 to start and run synchronously through the internal program, driving several rollers 7 to rotate synchronously (motors 52 are servo motors).

[0025] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the adjusting component 6 includes a mounting plate 61, which is rotatably sleeved on the top of the corresponding mounting base 51, and the mounting plate 61 is fixedly connected to the limiting plate 8 by bolts. The mounting groove of the mounting plate 61 is fixedly installed with a second motor 62, and the driving end of the second motor 62 is fixedly connected to the corresponding mounting base 51. In this embodiment, please refer to Figure 2 and Figure 4As shown, when adjusting the angle of roller 7, the external control system controls several motors 62 to start and run synchronously through the internal program. The motors 7 are driven to rotate 90 degrees synchronously in the forward or reverse direction through the mounting base 51 (motor 52 is a servo motor).

[0026] Working principle: When using this improved fiberglass reinforced plastic (FRP) pipe inner and outer layer grinding device, the FRP pipe is pushed between several grinding plates 4 in sequence by the cooperation of the roller-driven conveyor and the rollers 7. Then, the FRP pipe is driven to rotate by the rollers 7, so that the inner and outer sides of the FRP pipe are ground by friction between the grinding plates 4 and the inner and outer sides of the FRP pipe. Afterwards, the rotating rollers 7 push the FRP pipe out from between the grinding plates 4, and the FRP pipe is moved to the subsequent processing position by the roller-driven conveyor. The device has a high degree of automation and can be well adapted to the processing operation of the production line.

[0027] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above are only preferred embodiments of this utility model.
