Description

Technical Field

[0001] The invention belongs to the technical field of plastic composite pipe production, and specifically relates to a continuous fiber reinforced thermoplastic composite pipe production device and process. Background Art

[0002] As the first line of defense against corrosion and high pressure, the effect of the reinforcement layer finally formed by the glass fiber reinforced tape is crucial. The winding operation of the glass fiber reinforced tape is usually completed by winding equipment. In the winding operation, it is relatively easy to ignore the flattening state of the glass fiber reinforced tape during the unwinding process. Low flatness will cause the problem of uneven winding thickness. If the foundation of the first step is not done well, it will affect the effect of the heating and melting of the glass fiber reinforced tape layer and the rolling and melting of the glass fiber reinforced tape. The surface of the heated and melted glass fiber reinforced tape layer will be locally raised, and the surface of the glass fiber reinforced tape will also be uneven after subsequent rolling, which will affect the production and processing quality. In addition, the existing continuous fiber reinforced thermoplastic plastic composite pipe production equipment needs to use an additional drive device to drive the unwinding device to move when winding the fiber reinforced tape in order to evenly wind the fiber reinforced tape on the surface of the composite pipe. The moving speed of the unwinding device cannot change at any time with the winding speed of the plastic composite pipe. The winding effect of the fiber reinforced tape is poor, and the fiber reinforced tape cannot be automatically cut after the fiber reinforced tape is wound. Summary of the invention

[0008] Preferably, the transmission assembly includes a driving wheel group and a driven wheel group, and the driving wheel group and the driven wheel group are respectively fixedly mounted on the outer side of the output shaft of the winding rotation module and one end of the screw drive member, and a transmission belt is connected between the driving wheel group and the driven wheel group.

[0009] Preferably, the unwinding device includes a wire-reeling assembly mounting plate, a wire-reeling rotating module is fixedly provided on the rear side of the wire-reeling assembly mounting plate, the end of the output shaft of the wire-reeling rotating module is fixedly connected to a T-bolt rod, and a fiber-reinforced belt reel and a fixing nut assembly are sleeved on the outer side of the T-bolt rod.

[0010] Preferably, a torque sensor is provided between the end of the output shaft of the wire-releasing rotation module and the T-bolt rod;

[0011] Preferably, the fiber reinforced belt heating module comprises a heating box body, the top and bottom of the heating box body are provided with inlet and outlet openings, guide limit assemblies are symmetrically fixed on the outer sides of the inlet and outlet openings, and electric heating assemblies are symmetrically provided on both sides of the heating box body.

[0012] Preferably, the fiber reinforced belt automatic cutting module comprises an outer shell, an extrusion rod is inserted into one side of the outer shell, a first return spring is sleeved on the outer side of the extrusion rod, a sliding wheel group is fixedly provided at one end of the extrusion rod, a spacer is fixedly provided in the inner cavity of the outer shell below the sliding wheel group, guide columns are symmetrically inserted into the spacer, a special-shaped driving plate and a cutting knife are fixedly provided at the top and bottom ends of the guide columns, and a second return spring is sleeved on the outer side of the top end of the guide column:

[0013] S1. The lifting and lowering of the lifting slider can be controlled by rotating the adjusting screw on the pressure control module in the forward and reverse directions, and the height of the pressure roller can be adjusted. By adjusting the height of the pressure roller, the pressure of the pressure roller on the fiber reinforced belt wrapped around the outside of the plastic composite pipe can be adjusted. The fiber reinforced belt wrapped around the outside of the plastic composite pipe can be rolled and leveled by the pressure roller;

[0014] S2. After the fiber-reinforced tape reel is sleeved on the outside of the T-bolt rod, the fixing nut assembly is rotated to lock and fix the fiber-reinforced tape reel to complete the installation of the fiber-reinforced tape reel. Then, the plastic composite pipe to be processed is placed between the two groups of clamping plates. The hydraulic telescopic assembly drives one group of clamping plates to move so that the plastic composite pipe to be processed can be quickly clamped and fixed. After the plastic composite pipe is clamped and fixed, one end of the fiber-reinforced tape on the fiber-reinforced tape reel is connected to the outside of one end of the plastic composite pipe, and the winding and rotating module is opened. The winding and rotating module drives the plastic composite pipe to rotate to wind the fiber-reinforced tape. While the winding and rotating module rotates to wrap the fiber-reinforced tape around the outside of the plastic composite pipe, the winding and rotating module can drive the screw drive on the unwinding device drive mechanism to rotate through the transmission assembly. The rotation of the screw drive can drive the screw sleeve drive to move, and the screw sleeve drive can drive the unwinding device to move synchronously. Moreover, the winding speed of the winding rotating module changes and the moving speed of the unwinding device will also increase synchronously. When the plastic composite pipe is about to be wound, one end of the extruding rod on the fiber reinforced tape automatic cutting module conflicts with the limit baffle. At this time, the fiber reinforced tape automatic cutting module continues to move under the drive of the winding rotating module, and the extruding rod will squeeze the special-shaped driving plate through the sliding wheel group. The special-shaped driving plate will use the slope structure on the top to drive the cutting knife to move downward under the extrusion of the extruding rod to automatically cut the fiber reinforced tape. After the fiber reinforced tape is cut, the processed plastic composite pipe can be removed. Then, the winding rotating module is controlled to rotate in the opposite direction to drive the screw drive on the unwinding device driving mechanism to rotate in the opposite direction, so as to control the unwinding device to move in the opposite direction to reset, so as to carry out the next winding operation. While the unwinding device moves in the opposite direction to reset, the first reset spring and the second reset spring can be used to quickly reset the extruding rod and the cutting knife.

[0015] S3. The winding tension of the fiber reinforced tape can be detected in real time through the torque sensor between the wire-paying rotating module and the T-bolt rod. When the winding tension is large, the speed of the wire-paying rotating module is increased by controlling the single-chip microcomputer controller. When the winding tension is small, the speed of the wire-paying rotating module is decreased by controlling the single-chip microcomputer controller. When the fiber reinforced tape is unwound and wound, it passes through the fiber reinforced tape heating module. The fiber reinforced tape can be preheated by the electric heating component inside the fiber reinforced tape heating module, which can improve the adhesion between the fiber reinforced tape and the plastic composite pipe.

[0016] Compared with the prior art, the beneficial effect of the present invention is that when the present invention is in use, the lifting and lowering of the lifting slider can be controlled by rotating the adjusting screw on the pressure control module in the forward and reverse directions, and the height of the pressure roller can be adjusted. By adjusting the height of the pressure roller, the pressure of the pressure roller on the fiber reinforced belt wrapped around the outside of the plastic composite pipe can be adjusted, so that the pressure roller can better roll and flatten the fiber reinforced belt wrapped around the outside of the plastic composite pipe.

[0017] When the present invention is in use, the hydraulic telescopic component drives one group of clamping plates to move, so that the plastic composite pipe to be processed can be quickly clamped and fixed. After the plastic composite pipe is clamped and fixed, one end of the fiber reinforced tape on the fiber reinforced tape reel is connected to the outside of one end of the plastic composite pipe, and the winding and rotating module is opened. The winding and rotating module drives the plastic composite pipe to rotate to wind the fiber reinforced tape. While the winding and rotating module rotates to wind the fiber reinforced tape around the outside of the plastic composite pipe, the winding and rotating module can drive the screw drive member on the unwinding device drive mechanism to rotate through the transmission component, and the screw drive member rotates The rotation can drive the screw sleeve driving part to move, and the screw sleeve driving part can drive the unwinding device to move synchronously, and the winding speed of the winding rotating module changes and the moving speed of the unwinding device will also increase synchronously. When the plastic composite pipe is about to be wound, one end of the extrusion rod on the fiber reinforced belt automatic cutting module conflicts with the limit baffle. At this time, the fiber reinforced belt automatic cutting module continues to move under the drive of the winding rotating module, and the extrusion rod will squeeze the special-shaped driving plate through the sliding wheel group. The special-shaped driving plate will use the slope structure on the top to drive the cutting knife to move downward under the extrusion of the extrusion rod to automatically cut the fiber reinforced belt.

[0018] When the present invention is in use, the winding tension of the fiber reinforced belt can be detected in real time through the torque sensor between the wire-paying rotating module and the T-bolt rod. When the winding tension is large, the rotation speed of the wire-paying rotating module is increased by controlling the single-chip microcomputer controller. When the winding tension is small, the rotation speed of the wire-paying rotating module is reduced by controlling the single-chip microcomputer controller. When the fiber reinforced belt is unwound and wound, it passes through the fiber reinforced belt heating module. The fiber reinforced belt can be preliminarily preheated by the electric heating component inside the fiber reinforced belt heating module, thereby improving the adhesion between the fiber reinforced belt and the plastic composite pipe.

[0036] refer to Figure 2As shown, the fiber reinforced tape heating module 13 includes a heating box 1301, the top and bottom of the heating box 1301 are provided with inlet and outlet openings 1302, the outer sides of the inlet and outlet openings 1302 are symmetrically fixed with guide limit assemblies 1303, and the two sides of the heating box 1301 are symmetrically provided with electric heating assemblies 1304. When the fiber reinforced tape is unwound and wound, it passes through the fiber reinforced tape heating module 13, and the fiber reinforced tape can be preheated by the electric heating assembly 1304 inside the fiber reinforced tape heating module 13, so as to improve the adhesion between the fiber reinforced tape and the plastic composite pipe.

[0037] refer to Figure 4 As shown, the fiber reinforced belt automatic cutting module 14 includes an outer shell 1401, an extrusion rod 1402 is inserted on one side of the outer shell 1401, a first return spring 1403 is sleeved on the outer side of the extrusion rod 1402, a sliding wheel group 1404 is fixedly provided at one end of the extrusion rod 1402, and a partition plate 1405 is fixedly provided in the inner cavity of the outer shell 1401 below the sliding wheel group 1404, and a guide column 1406 is symmetrically inserted on the partition plate 1405, and a special-shaped driving plate 1407 and a cutting knife 1408 are fixedly provided at the top and bottom ends of the guide column 1406, and a second return spring 1409 is sleeved on the outer side of the top end of the guide column 1406. When the plastic composite pipe is about to be wound, one end of the extrusion rod 1402 on the fiber reinforced belt automatic cutting module 14 conflicts with the limit baffle 15. At this time, the fiber reinforced belt automatic cutting module 14 is in the winding rotation module 5. The extrusion rod 1402 continues to move under the drive of the sliding wheel group 1404, and the special-shaped driving plate 1407 uses the slope structure on the top to drive the cutting knife 1408 to move downward under the extrusion of the extrusion rod 1402. When the cutting knife 1408 moves downward, it cooperates with the cutting table below to automatically cut the fast fiber reinforced belt.

While the unwinding device 12 moves in the opposite direction for resetting, the first resetting spring 1403 and the second resetting spring 1409 can be used to quickly reset the extrusion rod 1402 and the cutting knife 1408.

[0038] refer to Figure 1-Figure 4 As shown, a continuous fiber reinforced thermoplastic composite pipe production process comprises the following steps:

[0039] S1. By rotating the adjusting screw 801 on the pressure regulating module 8 forward and reversely, the lifting and lowering of the lifting slider 804 can be controlled, and then the height of the pressing roller 9 can be adjusted. By adjusting the height of the pressing roller 9, the pressure of the pressing roller 9 on the fiber reinforced belt wound on the outside of the plastic composite pipe can be adjusted. The pressing roller 9 can be used to roll and flatten the fiber reinforced belt wound on the outside of the plastic composite pipe;

[0040] S2. After the fiber-reinforced tape reel 1204 is sleeved on the outside of the T-bolt rod 1203, the fixing nut assembly 1205 is rotated to lock and fix the fiber-reinforced tape reel 1204 to complete the installation of the fiber-reinforced tape reel 1204. Then, the plastic composite pipe to be processed is placed between the two groups of clamping plates 7. The hydraulic telescopic assembly 6 drives one group of clamping plates 7 to move, so that the plastic composite pipe to be processed can be quickly clamped and fixed. After the plastic composite pipe is clamped and fixed, the fiber-reinforced tape on the fiber-reinforced tape reel 1204 is tightened. The end is connected to the outside of one end of the plastic composite pipe, the winding rotation module 5 is opened, and the winding rotation module 5 drives the plastic composite pipe to rotate to wind the fiber reinforced tape. While the winding rotation module 5 rotates to wind the fiber reinforced tape around the outside of the plastic composite pipe, the winding rotation module 5 can drive the screw drive 1002 on the unwinding device drive mechanism 10 to rotate through the transmission component 11, and the screw drive 1002 can drive the screw sleeve drive 1003 to move, and the screw sleeve drive 1003 can drive the unwinding device 12 to move synchronously, and the winding rotation module 5 can drive the unwinding device 12 to move synchronously. The winding speed of the module 5 changes, and the moving speed of the unwinding device 12 will also increase synchronously. When the plastic composite pipe is about to be wound, one end of the extrusion rod 1402 on the fiber reinforced tape automatic cutting module 14 conflicts with the limit baffle 15. At this time, the fiber reinforced tape automatic cutting module 14 continues to move under the drive of the winding rotation module 5. The extrusion rod 1402 will squeeze the special-shaped driving plate 1407 through the sliding wheel group 1404. The special-shaped driving plate 1407 will drive the cutting knife 1408 under the extrusion of the extrusion rod 1402 using the slope structure on the top. The fiber reinforced tape is automatically cut by moving downward. After the fiber reinforced tape is cut, the processed plastic composite tube can be removed. Then, the winding rotation module 5 is controlled to rotate in the reverse direction to drive the screw drive member 1002 on the unwinding device drive mechanism 10 to rotate in the reverse direction, so as to control the unwinding device 12 to move in the reverse direction to reset, so as to perform the next winding operation. While the unwinding device 12 moves in the reverse direction to reset, the first reset spring 1403 and the second reset spring 1409 can be used to quickly reset the extrusion rod 1402 and the cutting knife 1408;

[0041] S3. The winding tension of the fiber reinforced tape can be detected in real time through the torque sensor between the pay-off rotating module 1202 and the T-bolt rod 1203. When the winding tension is large, the rotation speed of the pay-off rotating module 1202 is increased by controlling the single-chip microcomputer controller. When the winding tension is small, the rotation speed of the pay-off rotating module 1202 is reduced by controlling the single-chip microcomputer controller. When the fiber reinforced tape is unwound and wound, it passes through the fiber reinforced tape heating module 13. The fiber reinforced tape can be preheated by the electric heating component 1304 inside the fiber reinforced tape heating module 13, thereby improving the adhesion between the fiber reinforced tape and the plastic composite pipe.

[0042] Working principle of the present invention: The hydraulic telescopic component 6 drives one group of clamping plates 7 to move, so as to quickly clamp and fix the plastic composite pipe to be processed. After the plastic composite pipe is clamped and fixed, one end of the fiber reinforced tape on the fiber reinforced tape reel 1204 is connected to the outside of one end of the plastic composite pipe, and the winding rotation module 5 is opened. The winding rotation module 5 drives the plastic composite pipe to rotate to wind the fiber reinforced tape. While the winding rotation module 5 rotates to wind the fiber reinforced tape on the outside of the plastic composite pipe, the winding rotation module 5 can drive the screw drive member 1 on the unwinding device drive mechanism 10 through the transmission component 11. 002 rotates, the screw drive member 1002 rotates to drive the screw sleeve drive member 1003 to move, and the screw sleeve drive member 1003 can drive the unwinding device 12 to move synchronously, and the winding speed of the winding rotation module 5 changes, and the moving speed of the unwinding device 12 will also increase synchronously. When the plastic composite pipe is about to be wound, one end of the extrusion rod 1402 on the fiber reinforced belt automatic cutting module 14 conflicts with the limit baffle 15. At this time, the fiber reinforced belt automatic cutting module 14 continues to move driven by the winding rotation module 5, and the extrusion rod 1402 squeezes the special-shaped driving plate 1407 through the sliding wheel group 1404. The special-shaped driving plate 1407 uses the slope structure on the top to drive the cutting knife 1408 to move downward under the extrusion of the extrusion rod 1402 to automatically cut the fiber reinforced tape. After the fiber reinforced tape is cut, the processed plastic composite tube can be removed. Then, the winding rotation module 5 is controlled to rotate in the opposite direction to drive the screw drive member 1002 on the unwinding device driving mechanism 10 to rotate in the opposite direction, so as to control the unwinding device 12 to move in the opposite direction to reset, so as to perform the next winding operation. While the unwinding device 12 moves in the opposite direction to reset, the first reset spring 1403 and the second reset spring 1409 can be used to quickly reset the extrusion rod 1402. The rod 1402 and the cutting knife 1408 are reset. During winding, the fiber reinforced tape can be preheated by the electric heating component 1304 inside the fiber reinforced tape heating module 13 to improve the adhesion between the fiber reinforced tape and the plastic composite pipe. The lifting and lowering of the lifting slider 804 can be controlled by rotating the adjusting screw 801 on the pressure control module 8 in the forward and reverse directions.

4. The production process of a continuous fiber reinforced thermoplastic composite pipe production equipment according to any one of claims 1 to 3, characterized in that: The following steps are involved: S1. By rotating the adjusting screw (801) on the pressure regulating module (8) in forward and reverse directions, the lifting and lowering of the lifting slider (804) can be controlled, thereby adjusting the height of the pressing roller (9). By adjusting the height of the pressing roller (9), the pressure of the pressing roller (9) on the fiber reinforced belt wound on the outer side of the plastic composite pipe can be adjusted. The pressing roller (9) can be used to roll and flatten the fiber reinforced belt wound on the outer side of the plastic composite pipe; S2. After the fiber-reinforced tape reel (1204) is sleeved on the outside of the T-bolt rod (1203), the fixing nut assembly (1205) is rotated to lock and fix the fiber-reinforced tape reel (1204) to complete the installation of the fiber-reinforced tape reel (1204). Then, the plastic composite pipe to be processed is placed between the two groups of clamping plates (7). The hydraulic telescopic assembly (6) drives one group of clamping plates (7) to move so that the plastic composite pipe to be processed can be quickly clamped and fixed. After the plastic composite pipe is clamped and fixed, one end of the fiber-reinforced tape on the fiber-reinforced tape reel (1204) is connected to the On the outer side of one end of the plastic composite pipe, the winding rotation module (5) is opened, and the winding rotation module (5) drives the plastic composite pipe to rotate to wind the fiber reinforced tape. While the winding rotation module (5) rotates to wind the fiber reinforced tape on the outer side of the plastic composite pipe, the winding rotation module (5) can drive the screw drive member (1002) on the unwinding device drive mechanism (10) to rotate through the transmission component (11). The rotation of the screw drive member (1002) can drive the screw sleeve drive member (1003) to move, and the screw sleeve drive member (1003) can drive the unwinding device (12) to move synchronously, and the winding rotation module When the winding speed of the unwinding device (12) is changed by the change of the winding speed, the moving speed of the unwinding device (12) will also increase synchronously. When the plastic composite pipe is about to be wound, one end of the extrusion rod (1402) on the fiber reinforced tape automatic cutting module (14) contacts the limit baffle (15). At this time, the fiber reinforced tape automatic cutting module (14) continues to move under the drive of the winding rotating module (5). The extrusion rod (1402) will squeeze the special-shaped driving plate (1407) through the sliding wheel group (1404). The special-shaped driving plate (1407) will drive the cutting knife (1407) under the extrusion of the extrusion rod (1402) by the slope structure at the top. 08) moves downward to automatically cut the fiber reinforced tape. After the fiber reinforced tape is cut, the processed plastic composite tube can be removed. Then, the winding rotation module (5) is controlled to rotate in the opposite direction to drive the screw drive member (1002) on the unwinding device drive mechanism (10) to rotate in the opposite direction, thereby controlling the unwinding device (12) to move in the opposite direction to reset so as to perform the next winding operation. While the unwinding device (12) moves in the opposite direction to reset, the first reset spring (1403) and the second reset spring (1409) can be used to quickly reset the extrusion rod (1402) and the cutting knife (1408); S3. The winding tension of the fiber reinforced tape can be detected in real time by a torque sensor between the wire-releasing rotating module (1202) and the T-bolt rod (1203). When the winding tension is large, the speed of the wire-releasing rotating module (1202) can be increased by controlling the single-chip microcomputer controller. When the winding tension is small, the speed of the wire-releasing rotating module (1202) can be decreased by controlling the single-chip microcomputer controller. When the fiber reinforced tape is unwound and wound, it passes through the fiber reinforced tape heating module (13). The fiber reinforced tape can be preheated initially by the electric heating component (1304) inside the fiber reinforced tape heating module (13), thereby improving the adhesion between the fiber reinforced tape and the plastic composite pipe.
