Description

Technical Field

[0001] The invention belongs to the technical field of solid impurity filtering, and specifically refers to a special resin prepreg preparation device for in-situ repair of pipelines. Background Art

[0002] Resin prepreg is a higher strength material formed by combining resin and cloth base material. The first step in its preparation is to prepare resin. Resin is mostly made of raw materials extracted from fossil fuels such as coal. Some resins require certain temperature conditions when undergoing chemical reactions such as polymerization. Therefore, the reaction temperature is often controlled by heating during the preparation process to avoid uneven reaction or side reactions caused by inappropriate temperature.

[0003] Since the raw materials of the resin contain extracts from fossil fuels such as coal, they are often decomposed into smaller residues during the heating reaction process. Therefore, the residues need to be filtered and separated to prevent the residues from combining with the resin on the cloth base material and affecting product quality.

[0004] As we all know, the fluidity of most resins is closely related to temperature. The lower the temperature, the worse the fluidity. Therefore, resins at room temperature are mostly viscous. Therefore, the conventional post-residue filtration structure will greatly affect the filtration effect and efficiency due to the poor fluidity of the resin. Therefore, the most appropriate way is to filter the residue in time during the heating reaction process. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a special resin prepreg preparation device for in-situ repair of pipelines. During the heating reaction, the automatic residue collection component continuously collects the deposited residue. After collecting for a period of time, the automatic residue collection component is closed by the pressure sensing component, and the automatic residue collection component is removed from the tank body by the waterproof pneumatic suction cup, and a new automatic residue collection component is placed in the tank body to realize the residue circulation collection, which effectively solves the problem of residue deposition during the heating reaction and significantly improves the efficiency and effect of filtering small solid particle impurities in the resin.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a special resin prepreg preparation device for in-situ repair of pipelines, comprising a tank body, an automatic residue collection component, a timed automatic rotation component and an anti-water absorption pneumatic suction cup component, wherein the automatic residue collection component is arranged on the tank body, the timed automatic rotation component is arranged on the tank body, the anti-water absorption pneumatic suction cup component is located above the tank body, and the anti-water absorption pneumatic suction cup component is arranged on an external frame, the tank body comprises a tank body, a heating element, a material storage device and a pipeline, and the tank body is provided with a pressure relief valve, a material inlet and a recovery port.

[0007] Furthermore, an arc-shaped slide groove and a dovetail slide are provided on the outer surface of the tank body, a pressure hole, a notch and a positioning hole are provided on the inner surface of the tank body, a ball valve for controlling the outflow of liquid is provided on the pipeline, the pipeline is located at the bottom of the tank body, a boss stopper 1 is provided at the bottom of the inner surface of the feed port, the storage device is placed on the boss stopper 1, the storage device can be taken out from the feed port, a boss stopper 2 is provided at one end of the arc-shaped slide groove, and the heating element is located at the bottom of the tank body.

[0008] The automatic residue collection component includes an automatic shrinking elastic rod component, an automatic collection and sealing component and a pressure sensing component. The automatic shrinking elastic rod component is fixed on the tank body, the automatic collection and sealing component is placed on the automatic shrinking elastic rod component, and the pressure sensing component is located in the pressure hole.

[0009] The automatic residue collecting component is located below the material storage device. The area of ​​the residue collected by the automatic residue collecting component is much larger than that of the material storage device. The automatic residue collecting component can completely collect the deposited residue by covering the entire liquid surface of the tank body. The bottom of the automatic residue collecting component does not contact the bottom of the tank body, and the heating element at the bottom does not contact the residue. Therefore, the residue will not be burnt and agglomerated due to excessive temperature, reducing the possibility of clogging the pipeline.

[0010] Furthermore, the automatically retractable elastic rod assembly includes a sliding member, an elastically retractable member and a fixing portion, the sliding member slides on the arc-shaped slide groove of the tank body, the elastically retractable member slides in the positioning hole, and the fixing portion is connected to the notch of the tank body.

[0011] One end of the automatic shrinking elastic rod assembly is fixed on the inner surface of the tank body, and the other end of the automatic shrinking elastic rod assembly slides on the arc-shaped slide groove on the outer surface of the tank body to realize the shrinkage and expansion of the elastic shrinkable part inside the tank body.

[0012] Furthermore, the pressure sensing component includes a pressure sensing chamber, a push rod and a pressure chamber return spring. The pressure sensing chamber can sense the internal pressure from the tank body. The pressure sensing chamber is connected to the push rod. The pressure chamber return spring is located between the inner wall of the pressure hole and the pressure sensing chamber. The push rod is located at the center of the pressure chamber return spring.

[0013] The pressure sensing component uses an ingenious mechanical structure to sufficiently heat the raw materials in the tank body, making the chemical reaction more complete. As the heating time of the tank body increases, the internal pressure of the tank body increases, and the increased pressure causes the pressure sensing component to move, and then the pushing rod of the pressure sensing component pushes the sliding part to make the sliding part break away from the obstruction of the boss stopper 2, and the automatically contracting elastic rod assembly completes automatic contraction. At the same time, the pressure relief valve above the tank body reaches the critical value and starts to relieve pressure. The pressure relief valve transmits a signal to stop the heating element from heating. The critical value of the pressure relief valve is slightly higher than the pressure value of the moving sliding part of the pressure sensing component.

[0014] Furthermore, the automatic collection and closing assembly includes a fixing part, a filter screen assembly and a closing plate assembly. The automatic collection and closing assembly is connected to the elastically shrinkable part through the fixing part. The filter screen assembly includes elastic transverse ribs, longitudinal rods and elastic shrinkage ribs at the mesh mouth. The longitudinal rod is elastic and connected to the fixing part. The closing plate assembly includes a closing plate, a force transmission rod, a boss fixing device and a sleeve. The force transmission rod is arranged symmetrically on the left and right. One end of the force transmission rod is fixed on the longitudinal rod, and the other end of the force transmission rod is hinged on the boss fixing device. The boss fixing device is fixed to the bottom of the closing plate. The sleeve is fixed to the closing plate, and the sleeve rotates on the elastic shrinkage ribs at the mesh mouth.

[0015] When the automatic shrinking elastic rod assembly shrinks, the filter mesh assembly shrinks, and then the longitudinal rod drives the force transmission rod, and the symmetrically arranged force transmission rods move closer to each other. The force transmission rod drives the closing plate, so that the closing plate closes the filter mesh assembly, ensuring that when the automatic collection and closing assembly is moved out of the tank, residue will not overflow from the filter mesh assembly. Multiple automatic collection and closing assemblies can be replaced with each other and reused after cleaning.

[0016] Furthermore, the timed automatic rotation component includes a sensor, a shell, a drive component and a dovetail groove, the shell is equipped with a timer, the drive component is composed of a motor and a rotating wheel, the sensor is arranged on the shell, the dovetail groove is located on the surface of the shell, the dovetail groove slides on the dovetail slide, the motor is connected to the rotating wheel, and the rotating wheel rolls on the inner wall of the arc-shaped slide groove.

[0017] The sliding part breaks away from the obstruction of the boss stopper 2, and moves from the end of the arc-shaped slide groove where the boss stopper 2 is located to the position of the sensor at the other end of the arc-shaped slide groove. The sensor senses the collision of the sliding part, and the sensor transmits the signal to the timer. The timer promptly transmits the signal to the motor. The motor rotates the wheel to move on the arc-shaped slide groove, pushing the sliding part to slide on the arc-shaped slide groove, thereby completing the reset of the automatic retractable elastic rod assembly.

[0018] Furthermore, the anti-water absorption pneumatic suction cup assembly includes a hose, a telescopic rod, a suction cup, a seal, an air guide reset spring, an air guide and a manipulator, the upper end of the telescopic rod is connected to the manipulator, the lower end of the telescopic rod is connected to the suction cup, the lower end of the telescopic rod is provided with an air cavity and a contraction port, the upper end of the air cavity is connected to the hose, the contraction port is connected to the seal, the seal is elastic, the air guide is provided with an air guide cavity, an air guide hole and a boss stopper, and the air guide is arranged between the seal and the contraction port.

[0019] The anti-water absorption pneumatic suction cup assembly moves down into the tank body, so that the suction cup and the closing plate are gradually compressed, and the liquid between the suction cup and the closing plate is completely squeezed out. During the process, the air guide piece is pushed upward, and the air guide cavity on the air guide piece is not directly connected to the air cavity. The elastic sealing piece seals the contraction port, so that the pneumatic suction cup assembly has the function of isolating the liquid.

[0020] Furthermore, the closing plate continues to compress the elastic sealing part, and the air guide part continues to move upward. The air guide part is connected to the air cavity through the air guide hole. During the process, the hose continuously discharges the gas in the air cavity, causing the air cavity to generate negative pressure. The negative pressure generated by the air cavity makes the force between the suction cup and the closing plate stronger. The anti-water absorption pneumatic suction cup assembly drives the automatic residue collection assembly to move out of the tank body, and the hose releases gas to the air cavity to generate air pressure, so that the closing plate is separated from the suction cup, and the automatic residue collection assembly is recovered. The air guide part reset spring resets the air guide part, and the air guide hole moves downward, and the air guide part is disconnected from the air cavity. Then the anti-water absorption pneumatic suction cup assembly re-sucks up the clean automatic residue collection assembly and puts it into the tank body. At the same time, the heating element is heated to achieve the technical requirements for replacement of the automatic residue collection assembly.

[0021] The beneficial effects achieved by the present invention using the above structure are as follows:

[0022] (1) The automatic residue collection component proposed in this scheme is located below the material storage device. The area of ​​the residue collected by the automatic residue collection component is much larger than the area of ​​the material storage device. By covering the liquid surface of the entire tank body, the automatic residue collection component can completely collect the deposited residue. The bottom of the automatic residue collection component does not contact the bottom of the tank body, and the heating element at the bottom does not contact the residue. Therefore, the residue will not be burnt and agglomerated due to excessive temperature, thereby reducing the possibility of clogging the pipeline.

[0023] (2) The pressure sensing component proposed in this scheme uses an ingenious mechanical structure to fully heat the raw materials in the tank body, making the chemical reaction more complete. As the heating time of the tank body increases, the internal pressure of the tank body increases. The increased pressure causes the pressure sensing component to move, and then the push rod of the pressure sensing component pushes the sliding part, so that the sliding part breaks away from the obstruction of the boss stopper 2, and the elastic rod assembly automatically shrinks to complete the automatic shrinkage; at the same time, the pressure relief valve above the tank body reaches the critical value and starts to release the pressure. The pressure relief valve transmits a signal to stop the heating element from heating. The critical value of the pressure relief valve is slightly higher than the pressure value of the moving sliding part of the pressure sensing component.

[0024] (3) When the automatic retractable elastic rod assembly retracts, the filter assembly retracts, and then the longitudinal rod drives the force transmission rod, and the symmetrically arranged force transmission rods move closer to each other. The force transmission rod drives the closing plate, so that the closing plate closes the filter assembly, ensuring that when the automatic collection and closing assembly is removed from the tank, the residue will not overflow from the filter assembly. Multiple automatic collection and closing assemblies can be replaced with each other and reused after cleaning.

[0025] (4) The anti-water absorption pneumatic suction cup assembly proposed in this scheme moves down into the tank body, so that the suction cup and the closing plate are gradually compressed, and the liquid between the suction cup and the closing plate is completely squeezed out. During the process, the air guide member is pushed upward, and the air guide cavity on the air guide member is not directly connected to the air cavity. The elastic sealing member seals the contraction port, so that the anti-water absorption pneumatic suction cup assembly has the function of isolating the liquid.

[0026] (5) The anti-water absorption pneumatic suction cup assembly proposed in this scheme continues to compress the elastic sealing member through the closing plate, and the air guide member continues to move upward. Through the air guide hole, the air guide member is connected to the air cavity. During the process, the hose continuously discharges the gas in the air cavity, so that the air cavity generates negative pressure. The negative pressure generated by the air cavity makes the force between the suction cup and the closing plate stronger. The anti-water absorption pneumatic suction cup assembly drives the automatic residue collection assembly to move out of the tank body. The hose releases gas to the air cavity to generate air pressure, so that the closing plate is separated from the suction cup, and the automatic residue collection assembly is recovered. The air guide member resets the air guide member by the air guide member reset spring, and the air guide hole moves downward. The air guide member is disconnected from the air cavity, and then the anti-water absorption pneumatic suction cup assembly sucks up the clean automatic residue collection assembly again and puts it into the tank body, thereby realizing the technical requirements for replacing the automatic residue collection assembly.

[0027] (6) The timing automatic rotation assembly proposed in this scheme includes a sliding member, which is disengaged from the obstruction of the boss stopper 2. The sliding member moves from one end of the arc-shaped slide groove where the boss stopper 2 is located to the position of the sensor at the other end of the arc-shaped slide groove. The sensor senses the collision of the sliding member, and the sensor transmits the signal to the timer. The timer promptly transmits the signal to the motor. The motor rotates the wheel to move on the arc-shaped slide groove, pushing the sliding member to slide on the arc-shaped slide groove, thereby completing the reset of the automatic retractable elastic rod assembly.

[0047] like Figure 1-Figure 15 As shown, the present invention proposes a special resin prepreg preparation device for in-situ pipeline repair, comprising a tank body 1, an automatic residue collection component 2, a timed automatic rotation component 3 and an anti-water absorption pneumatic suction cup component 4, wherein the automatic residue collection component 2 is arranged on the tank body 1, the timed automatic rotation component 3 is arranged on the tank body 1, and the anti-water absorption pneumatic suction cup component 4 is arranged above the tank body 1.

[0048] The tank body 1 includes a tank body 11, a heating element 12, a material storage device 13 and a pipeline 14. The tank body 11 is provided with a pressure relief valve 111, a material inlet 112 and a recovery port 113. The outer surface of the tank body 11 is provided with an arc-shaped slide groove 114 and a dovetail slide 118.

[0049] A ball valve 141 is provided on the pipeline 14, and the pipeline 14 is located at the bottom of the tank body 11. A boss stopper 1121 is provided at the bottom of the inner surface of the feed port 112, and the storage device 13 is placed on the boss stopper 1121. The storage device 13 can be taken out from the feed port 112, and a boss stopper 2 1141 is provided at one end of the arc chute 114. The heating element 12 is located at the bottom of the tank body 11.

[0050] The automatic residue collection component 2 includes an automatic shrinking elastic rod component 21, an automatic collection and sealing component 22 and a pressure sensing component 23.

[0051] The automatic residue collection component 2 is located below the material storage device 13. The area of ​​the residue collected by the automatic residue collection component 2 is much larger than that of the material storage device 13. The automatic residue collection component 2 can completely collect the deposited residue by covering the entire liquid surface of the tank body 1. The bottom of the automatic residue collection component 2 does not contact the bottom of the tank body 11, and the heating element 12 at the bottom does not contact the residue. Therefore, the residue will not be burnt and agglomerated due to excessive temperature, thereby reducing the possibility of clogging the pipeline 14.

[0052] The automatically retractable elastic rod assembly 21 includes a sliding member 211, an elastically retractable member 212 and a fixing portion 213. The sliding member 211 can slide on the arc-shaped slide groove 114 of the tank body 11. The fixing portion 213 is fixed in the notch 116 of the tank body 11. The elastically retractable member 212 passes through the positioning hole 117. The elastically retractable member 212 can slide in the positioning hole 117. The elastically retractable member 212 elastically contracts and expands inside the tank body 11. The sliding member 211 is provided with a groove 2111.

[0053] One end of the automatic shrinking elastic rod assembly 21 is fixed to the inner surface of the tank body 11, and the other end of the automatic shrinking elastic rod assembly 21 slides on the arc-shaped slide groove 114 on the outer surface of the tank body 11, so that the elastic shrinkable part 212 can be shrunk and expanded inside the tank body 1.

[0054] The pressure sensing assembly 23 includes a pressure sensing chamber 231, a push rod 232 and a pressure chamber return spring 233. The pressure sensing chamber 231 is connected to the interior of the tank body 1. The pressure sensing chamber 231 is connected to the push rod 232. The pressure chamber return spring 233 is located between the inner wall of the pressure hole 115 and the pressure sensing chamber 231. The push rod 232 is located at the center of the pressure chamber return spring 233.

[0055] The pressure sensing component 23 uses an ingenious mechanical structure to sufficiently heat the raw materials in the tank body 1 to make the chemical reaction more complete. As the heating time of the tank body 1 increases, the internal pressure of the tank body 1 increases. The increased pressure causes the pressure sensing component 23 to move, and then the pushing rod 232 of the pressure sensing component 23 pushes the sliding member 211, so that the sliding member 211 is free from the obstruction of the boss stopper 1141, and the elastic rod component 21 automatically contracts to complete the automatic contraction.

[0056] The automatic collection and closure assembly 22 includes a fixing member 221, a filter assembly 222 and a closure plate assembly 223. The automatic collection and closure assembly 22 is connected to the elastically contractible member 212 through the fixing member 221. The filter assembly 222 includes an elastic transverse rib 2221, a longitudinal rod 2222 and a net-port elastic contraction rib 2223. The longitudinal rod 2222 is elastic and is connected to the fixing member 221. The closure plate assembly 223 includes a closure plate 22 31. The force transmission rod 2232, the boss fixing device 2233 and the sleeve 2234. The force transmission rod 2232 is arranged symmetrically on the left and right. One end of the force transmission rod 2232 is fixed on the longitudinal rod 2222, and the other end of the force transmission rod 2232 is hinged on the boss fixing device 2233. The boss fixing device 2233 is fixed to the bottom of the closing plate 2231. The sleeve 2234 is connected to the closing plate 2231, and the sleeve 2234 rotates on the elastic shrinkage rib 2223 of the mesh opening.

[0057] When the automatically shrinking elastic rod assembly 21 shrinks, the filter mesh assembly 222 shrinks, and then the longitudinal rod 2222 drives the force transmission rod 2232, and the symmetrically arranged force transmission rods 2232 move closer to each other, and the force transmission rod 2232 drives the closing plate 2231, so that the closing plate 2231 closes the filter mesh assembly 222, ensuring that when the automatic collection and closing assembly 22 is moved out of the tank body 1, residues will not overflow from the filter mesh assembly 222, and multiple automatic collection and closing assemblies 22 can be replaced with each other and reused after cleaning.

[0058] The anti-water absorption pneumatic suction cup assembly 4 includes a hose 41, a telescopic rod 42, a suction cup 43, a seal 44, an air guide reset spring 45, an air guide 46 and a manipulator 47. The upper end of the telescopic rod 42 is connected to the manipulator 47, and the lower end of the telescopic rod 42 is connected to the suction cup 43. The lower end of the telescopic rod 42 is provided with an air cavity 421 and a contraction port 422. The upper end of the air cavity 421 is connected to the hose 41, and the contraction port 422 is connected to the seal 44. The seal 44 is elastic. The air guide 46 includes an air guide cavity 461, an air guide hole 462 and a boss stopper 463. The air guide 46 is arranged between the seal 44 and the contraction port 422.

[0059] The anti-water absorption pneumatic suction cup assembly 4 moves down into the tank body 1, so that the suction cup 43 and the closing plate 2231 are gradually compressed, and the liquid between the suction cup 43 and the closing plate 2231 is completely squeezed out. During the process, the air guide member 46 is pushed upward, and the air guide cavity 461 on the air guide member 46 is not directly connected to the air cavity 421. The sealing member 44 seals the contraction port 422, so that the anti-water absorption pneumatic suction cup assembly 4 has the function of isolating the liquid.

[0060] The closing plate 2231 continues to compress the sealing member 44, and the air guide member 46 continues to move upward, and the air guide cavity 461 is connected with the air cavity 421 through the air guide hole 462. During the process, the hose 41 continuously discharges the gas in the air cavity 421, so that the air cavity 421 generates a negative pressure. The negative pressure generated by the air cavity 421 makes the force between the suction cup 43 and the closing plate 2231 stronger, and the anti-water absorption pneumatic suction cup assembly 4 drives the automatic residue collection assembly 2 to move out of the tank body 1, and the hose 41 releases gas to the air cavity 421 to generate air pressure, so that the closing plate 2231 is separated from the suction cup 43, and the automatic residue collection assembly 2 is recovered. The air guide member reset spring 45 resets the air guide member 46, and the air guide hole 462 moves downward, and the air guide member 46 is disconnected from the air cavity 421. The anti-water absorption pneumatic suction cup assembly 4 re-sucks up the clean automatic residue collection assembly 2 and puts them into the tank body 1. At the same time, the heating member 12 starts to heat, thereby achieving the technical requirements for replacing the automatic residue collection assembly 2.

[0061] The timing automatic rotation component 3 includes a sensor 31, a shell 32, a dovetail groove 33 and a driving component 34. A timer 321 is arranged inside the shell 32. The driving component 34 includes a motor 341 and a rotating wheel 342. The sensor 31 is arranged on the shell 32. The dovetail groove 33 slides on the dovetail slide 118. The motor 341 is connected to the rotating wheel 342, and the rotating wheel 342 rolls on the inner wall of the arc-shaped slide 114.

[0062] The sliding member 211 breaks away from the obstruction of the boss stopper 1141, and the sliding member 211 moves from one end of the arc-shaped slide groove 114 where the boss stopper 1141 is located to the position of the sensor 31 at the other end. The sensor 31 senses the collision of the sliding member 211, and the sensor 31 transmits the signal to the timer 321. The timer 321 promptly transmits the signal to the motor 341. The motor 341 rotates the rotating wheel 342 to move the rotating wheel 342 on the arc-shaped slide groove 114, pushing the sliding member 211 to slide on the arc-shaped slide groove 114, thereby completing the automatic retraction of the elastic rod assembly 21. Reset.

[0063] When in use, raw materials are added by opening the feed port 112, and the raw materials are stored in the storage device 13. The feed port 112 is closed, and the heating element 12 heats the tank body 1. As the heating time increases, the internal pressure of the closed tank body 1 gradually increases, and the increased pressure causes the pressure sensing component 23 to move, and then the push rod 232 of the pressure sensing component 23 pushes the sliding member 211. When the groove 2111 on the sliding member 211 moves beyond the boss stopper 1141, the sliding member 211 will be separated from the obstruction of the boss stopper 1141, and the elastically shrinkable member 212 will restore its elastic deformation and automatically shrink through the positioning hole 117 of the tank body 11. At the same time, the pressure relief valve 111 above the tank body 11 reaches a critical value and starts to release pressure. The pressure relief valve 111 transmits a signal to stop the heating element 12 from heating. The critical value of the pressure relief valve 111 is slightly higher than the pressure value of the pressure sensing component 23 moving the sliding member 211.

[0064] Because the fixing member 221 is connected to the elastically shrinkable member 212, as the elastically shrinkable member 212 shrinks, the mesh elastic shrinkage ribs 2223 on the filter assembly 222 shrink, the mesh elastic shrinkage ribs 2223 shrink, the longitudinal rod 2222 recovers its elastic deformation, and the longitudinal rod 2222 is connected to the force transmission rods 2232 which are arranged symmetrically on the left and right. The force transmission rods 2232 rotate and merge with the deformation of the longitudinal rod 2222, and the force transmission rods 2232 push the closing plate 2231, and the closing plate 2231 rotates on the mesh elastic shrinkage ribs 2223 following the sleeve 2234, so that the closing plate 2231 When the filter assembly 222 is restored to a horizontal position, the closing plate 2231 completes the closing of the filter assembly 222. At this time, the residue collection seal is completed, the recovery port 113 is opened, and the manipulator 47 of the anti-water absorption pneumatic suction cup assembly 4 controls the telescopic rod 42 to enter the tank body 11 through the recovery port 113. The telescopic rod 42 pushes the suction cup 43 connected at the lower end so that the suction cup 43 is adsorbed on the surface of the closing plate 2231 and squeezed against each other. The liquid between the suction cup 43 and the closing plate 2231 is gradually squeezed out. During the process, the air guide 46 is gradually lifted up by the closing plate 2231, and the air guide hole 462 on the air guide 46 moves upward. The liquid is completely After the extrusion, as the telescopic rod 42 continues to push the suction cup 43, the closing plate 2231 begins to squeeze the elastic sealing member 44, and the air guide member 46 continues to move upward. The elastic sealing member 44 is squeezed to a certain extent, and the air guide cavity 461 of the air guide member 46 can be connected with the air cavity 421 through the air guide hole 462. During the process, the hose 41 continuously discharges the gas in the air cavity 421 to generate negative pressure. When the air guide member 46 is connected with the air cavity 421, the negative pressure of the air cavity 421 will act between the suction cup 43 and the closing plate 2231, making the suction stronger. The manipulator 47 retracts the telescopic rod 42, and the anti-water absorption pneumatic suction cup assembly 4 drives the automatic collection and sealing component 22 to move out of the tank body 1, and then the hose 41 releases gas to the air cavity 421. The gas pressure of the air cavity 421 causes the sealing plate 2231 to separate from the suction cup 43, completing the recovery of the automatic collection and sealing component 22. Because the sealing plate 2231 is separated, the air guide reset spring 45 resets the air guide 46, and the air guide cavity 461 is disconnected from the air cavity 421. The hose 41 stops releasing gas, and then the anti-water absorption pneumatic suction cup component 4 sucks up the clean automatic collection and sealing component 22 and puts it back into the tank body 1, and is fixed by the fixing member 221 and placed on the self-elastic shrinkable member 212;

[0065] When the anti-water absorption pneumatic suction cup assembly 4 is working, due to the contraction of the elastically contractible member 212, the sliding member 211 slides from one end of the boss stopper 1141 to one end of the timing automatic rotation assembly 3 in the arc chute 114, so that the sliding member 211 touches the sensor 31, and the sensor 31 transmits a signal to the timer 321, and waits for the timer 321 to end, so that the motor 341 rotates forward, and the motor 341 drives the rotating wheel 342 to rotate, and the rotating wheel 342 drives the entire timing automatic rotation assembly 3 to slide on the dovetail slide 118, and pushes the sliding member 211 to move back to one end close to the boss stopper 1141, and after being fixed on the boss stopper 1141, the automatic contraction elastic rod assembly 21 is reset, and the automatic collection and closure assembly 22 is unfolded in the tank body 1, and the residue collection is restarted. At the same time, the timer 321 transmits a signal to the motor 341, so that the motor 341 rotates in the reverse direction, and the timing automatic rotation assembly 3 returns to the initial position on the arc chute 114.

[0066] After the reaction is completed, the liquid resin inside the tank body 1 can be discharged by opening the ball valve 141, and then coated on the cloth base material through an external coating mechanism. After the bonding is completed, the preparation of the resin prepreg can be completed.

[0067] The above is the overall workflow of the present invention. The actual process is very simple and forms a closed-loop work, which provides a feasibility for realizing automated production.
