Description

Technical Field

[0001] This invention relates to the field of ultraviolet light curing inner lining hose production technology, specifically to a production system for ultraviolet light curing inner lining hoses. Background Technology

[0002] With the continuous improvement of urban infrastructure construction, the aging and damage of underground pipelines (such as drainage, gas, and water supply pipelines) are becoming increasingly prominent. As an efficient and environmentally friendly trenchless pipeline repair technology, UV curing lining repair technology has been widely used in underground pipeline repair projects due to its advantages such as short construction cycle, minimal impact on the surrounding environment, and long service life of the repaired pipeline. Among them, UV curing lining hose is the core consumable of this technology, and its quality directly determines the pipeline repair effect and service life. The raw materials of the lining hose usually include resin matrix (such as unsaturated polyester resin, epoxy resin), curing agent, and other additives. Existing mixing equipment is mostly a single screw stirring structure, which is prone to the agglomeration of powdered raw materials and uneven dispersion of liquid raw materials, resulting in large fluctuations in the strength, toughness, and other mechanical properties of the finished hose.

[0003] Chinese Patent Application No. 202210209295.8 discloses a dual-shaft humidifying mixer. The dual-shaft humidifying mixer includes a mixing chamber, a mixing shaft, a drive device, and a humidifying chamber. The drive device is connected to the mixing shaft at the chamber wall of the mixing chamber via a coupling. A sealing body is arranged on the outside of the coupling. The sealing body is connected to a cleaning structure for cleaning the inner cavity of the sealing body. However, it is inconvenient to clean the inside after use.

[0004] Secondly, some existing mixing devices cannot adapt to materials in various forms. When mixing viscous, liquid, and powdered materials together, due to the high viscosity of viscous materials, it is difficult to uniformly disperse the liquid and powdered materials when they are mixed together, resulting in the inability to achieve uniform mixing of liquid and powdered materials with viscous materials. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a production system for ultraviolet light curing inner lining hoses. When mixing raw materials, the uniform mixing between raw materials of different forms effectively prevents the agglomeration of powdered and liquid raw materials, and is easy to clean after use, preventing viscous materials from adhering to the inside. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a production system for ultraviolet-cured inner lining hoses, comprising a raw material mixing module, an unwinding module, a resin impregnation module, a needle punching module, a pre-curing module, an online monitoring module, a coating module, a winding module, and a central control module for coordinating the operation of each module, connected in sequence. The raw material mixing module includes a frame, a mixing unit is provided on the top of the frame, a liquid addition unit is provided on the mixing unit, and a material homogenization unit and a cleaning unit are provided inside the mixing unit.

[0007] The mixing unit includes a mixing chamber located at the top of the frame. Both sides of the interior of the mixing chamber are rotatably connected to a mounting shaft. The mounting shaft is equipped with mixing blades, and a drive mechanism is connected to the end of the mounting shaft.

[0008] The material equalization unit includes a roller, on which a mesh plate is wound. The end of the mesh plate is connected to a traction mechanism, and an electromagnetic plate is embedded on the bottom surface of the mesh plate.

[0009] The cleaning unit includes two symmetrically arranged electric slide rails. The bottom of the sliding component of the electric slide rail is provided with a scraper. The top sides of both sides of the scraper are provided with mounting grooves. Movable seats are slidably connected in the mounting grooves. Rotary rollers are rotatably connected between the movable seats on both sides. An electric telescopic rod is provided between the movable seats and the top of the mounting groove.

[0010] Preferably, the bottom of the frame is movably connected to both the front and rear ends with support legs, and a hydraulic rod is provided between the top of the support leg at the rear end and the frame.

[0011] Preferably, the mixing blades are spirally arranged along the axial direction of the mounting shaft, and the mixing blades on both sides of the mounting shaft are staggered. The mixing blades are made of ferromagnetic material.

[0012] The mixing chamber has a feed hopper at the top front end, a discharge frame at the bottom rear end, a sealing plate at the bottom of the discharge frame, and a vision sensor on the top side inside the mixing chamber.

[0013] Preferably, the drive mechanism includes two meshing gears, a drive motor, and a reducer. The two gears are respectively fixedly sleeved on the ends of the mounting shafts on both sides. The drive motor and the reducer are both located on the top of the frame. The output shaft of the drive motor and the input shaft of the reducer are connected by a belt drive mechanism. The output shaft of the reducer is fixedly connected to the end of one of the mounting shafts.

[0014] Preferably, the liquid addition unit includes an inlet pipe and a liquid addition hood. The inlet pipe is located on the side of the mixing chamber and is connected to an external liquid supply system. The liquid addition hood is located on the top of the mixing chamber. Branch pipes are evenly distributed on the liquid addition hood, and each branch pipe is connected to the inlet pipe. Spray nozzles are evenly distributed at the bottom of each branch pipe.

[0015] Preferably, the roller is rotatably connected to the front end of the mixing chamber via a support, the mesh plate is made of flexible material, and a spiral spring is sleeved at the end of the roller, with the two ends of the spiral spring being fixedly connected to the roller and the support, respectively.

[0016] Preferably, the traction mechanism includes a traction rope and a roller. One end of the traction rope is fixedly connected to the end of the mesh plate. The roller is rotatably connected to the tail end face of the mixing bin through a frame plate. The other end of the traction rope passes through the tail end face of the mixing bin and is fixedly connected to the roller. A traction motor is provided on the side of the frame plate, and the output shaft of the traction motor is fixedly connected to the end of the roller.

[0017] Preferably, the two electric slide rails are respectively located on both sides of the inner top surface of the mixing chamber, and the scraper is a U-shaped structure that fits against the inner wall of the mixing chamber, with inclined surfaces on both sides of the scraper.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In this invention, when adding powder raw materials, the powder raw materials fall onto a uniformly unfolding screen plate through the feed hopper, so that the powder can be evenly spread. The screen plate moves horizontally back and forth under the drive of the traction motor and gradually falls through the mesh, avoiding local accumulation of powder raw materials on the bottom side of the mixing chamber and improving the uniformity of powder raw material mixing.

[0020] 2. When liquid raw materials are added, the liquid raw materials are sprayed out from the nozzle through the pressurization system. After the liquid raw materials are sprayed onto the screen plate, they are further dispersed into multiple fine streams by the mesh of the screen plate, which significantly increases the contact area between the liquid raw materials and other raw materials, thereby improving the uniformity of mixing and preventing the liquid raw materials from accumulating locally.

[0021] 3. When the present invention detects clumps of material on the surface of the mesh plate by a vision sensor, the scraper is driven by an electric slide rail. The scraper drives the rotating roller to move horizontally. When the rotating roller is about to reach the clumps of material, the rotating roller is moved downward by an electric telescopic rod to fit against the surface of the mesh plate, and the rotating roller continues to move towards the clumps of material. The rotation of the rotating roller can crush the clumps of material.

[0022] 4. When the mesh plate is clogged, the present invention first energizes the electromagnetic plate at the bottom of the mesh plate to generate magnetism. When the mixing blade rotates around the mounting shaft, the electromagnetic plate and the mixing blade correspond to generate magnetic attraction. The continuous rotation of the mixing blade causes the mesh plate to vibrate at high frequency. In conjunction with the electric telescopic rod driving the rotating roller to move up and down and collide with the mesh plate, the mesh plate generates high-frequency micro-amplitude vibration, effectively shaking off the particles that clog the holes.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-6 The present invention provides a technical solution: a production system for ultraviolet light curing inner lining hoses, comprising a raw material mixing module, an unwinding module, a resin impregnation module, a needle punching module, a pre-curing module, an online monitoring module, a coating module, a winding module, and a central control module for coordinating the operation of each module, connected in sequence.

[0032] Specifically, the raw material mixing module is used to mix the resin matrix raw materials, and the mixed raw materials are supplied to the resin impregnation module.

[0033] The unwinding module, comprising multiple yarn frames and winding rods, is used to continuously release glass fiber braided sleeves, inner protective layer, and outer protective layer materials.

[0034] The resin impregnation module uses a closed impregnation tank with guide rollers, pressure rollers and metering scraper rollers inside. By precisely controlling the gap and pressure between the scraper rollers, it ensures that the glass fiber woven sleeve is fully and evenly impregnated with resin, and precisely controls the resin content.

[0035] The needle-punching module, located after the impregnation module, includes one or more sets of needle rollers. The needles on the needle rollers penetrate the impregnated tubing, mechanically connecting the inner protective layer and the impregnated glass fiber layer together, and extruding internal air bubbles to further enhance the interlayer bonding force.

[0036] The pre-curing module, located after the needle punching module, uses an array of ultraviolet lamps to initially irradiate the resin-impregnated tubing, initiating a preliminary cross-linking reaction of the resin, giving it a certain initial strength and cohesive force, facilitating subsequent processing, and preventing adhesion during winding.

[0037] The online monitoring module, including a beta-ray thickness gauge and / or an infrared spectrometer, measures the thickness and resin content of the hose in real time without contact and feeds the data back to the central control module. The central control module can automatically adjust the gap of the scraper roller or the delivery rate of the resin pump based on the feedback to achieve closed-loop control.

[0038] The coating module precisely covers the outer surface of the hose with an outer protective layer, such as polyethylene (PE) film, protecting the hose from contamination and abrasion during handling and storage.

[0039] The winding module adopts a fully automatic dual-station rotary winding machine, equipped with a servo motor and tension sensor, which can achieve constant tension winding and automatically switch to another reel after one roll is completed, so as to achieve continuous winding without stopping the machine and ensure that the winding quality is neat and tight.

[0040] The central control module integrates a PLC and a human-machine interface to centrally control the speed, tension, temperature, and ultraviolet light intensity of the entire production line, and to automatically adjust based on online monitoring data, thereby achieving intelligent production.

[0041] The raw material mixing module includes a frame 1, with support legs 101 movably connected to both the front and rear ends of the bottom of the frame 1. A hydraulic rod 102 is provided between the top of the support leg 101 at the rear end and the frame 1.

[0042] Specifically, the top of the hydraulic rod 102 is hinged to the bottom of the frame 1 via a hinge seat, and the hinge seat is slidably connected to the bottom of the frame 1. The extension and retraction of the hydraulic rod 102 is used to realize the up and down movement of the tail of the frame 1, thereby adjusting the height of the tail of the frame 1.

[0043] The top of the frame 1 is provided with a mixing unit 2, the mixing unit 2 is provided with a liquid adding unit 3, and the mixing unit 2 is provided with a material equalization unit 4 and a cleaning unit 5.

[0044] Specifically, the mixing unit 2 is used for mixing various raw materials, the liquid addition unit 3 is used for adding liquid raw materials, the material equalization unit 4 is used for uniformly dispersing raw materials, and the cleaning unit 5 is used for cleaning the inner wall of the mixing chamber 201.

[0045] The mixing unit 2 includes a mixing chamber 201 located at the top of the frame 1. A feed hopper 2011 is provided at the front end of the top of the mixing chamber 201, and a discharge frame 2012 is provided at the rear end of the bottom of the mixing chamber 201. A sealing plate is provided at the bottom of the discharge frame 2012. A vision sensor is provided on the top side inside the mixing chamber 201. Mounting shafts 202 are rotatably connected to both sides inside the mixing chamber 201. Mixing blades 203 are provided on the mounting shafts 202. The mixing blades 203 are spirally arranged along the axial direction of the mounting shafts 202. The mixing blades 203 on the mounting shafts 202 on both sides are staggered. A drive mechanism is driven to the end of the mounting shafts 202.

[0046] Specifically, the feed hopper 2011 is used for feeding viscous and powdery raw materials, the discharge frame 2012 is used for discharging the mixed materials, and the sealing plate seals the discharge frame 2012 before the mixing is completed. The vision sensor is used to monitor the mixing state of the raw materials in the mixing chamber 201. The outside of the mixing chamber 201 is equipped with a heating module to heat the raw materials in the mixing chamber 201 in order to maintain a good flow state of the viscous material in the mixing chamber 201.

[0047] The drive mechanism includes two meshing gears 204, a drive motor 205, and a reducer 206. The two gears 204 are respectively fixedly sleeved on the ends of the mounting shafts 202 on both sides. The drive motor 205 and the reducer 206 are both located on the top of the frame 1. The output shaft of the drive motor 205 and the input shaft of the reducer 206 are connected by a belt drive mechanism. The output shaft of the reducer 206 is fixedly connected to the end of one of the mounting shafts 202.

[0048] Specifically, during the mixing process, the drive motor 205 drives one of the mounting shafts 202 to rotate through the belt drive mechanism and the reducer 206. Under the action of two meshing gears 204, the mounting shafts 202 on both sides rotate synchronously. The rotation of the spirally arranged mixing blades 203 achieves the mixing of various raw materials through shearing and kneading.

[0049] The liquid addition unit 3 includes an inlet pipe 301 and a liquid addition cover 302. The inlet pipe 301 is located on the side of the mixing chamber 201 and is connected to an external liquid supply system. The liquid addition cover 302 is located on the top of the mixing chamber 201. Branch pipes 303 are evenly arranged on the liquid addition cover 302, and each branch pipe 303 is connected to the inlet pipe 301. Nozzles 304 are evenly arranged at the bottom of the branch pipes 303.

[0050] Specifically, the liquid raw material is pressurized by an external liquid supply system and pumped into the inlet pipe 301, then enters each branch pipe 303 through the inlet pipe 301, and is sprayed into the mixing chamber 201 through the nozzle 304 to realize the feeding of liquid raw material.

[0051] The material equalization unit 4 includes a roller 402, which is rotatably connected to the front end of the mixing chamber 201 via a support 401. A mesh plate 403 is wound on the roller 402. The mesh plate 403 is made of flexible material. A spiral spring 404 is sleeved on the end of the roller 402. The two ends of the spiral spring 404 are fixedly connected to the roller 402 and the support 401, respectively. A traction mechanism is driven to the end of the mesh plate 403.

[0052] Specifically, the screen plate 403 is made of a flexible material for easy storage and extension, allowing it to be wound and unwound on the roll 402 as needed. The spiral spring 404 is used to achieve the winding and resetting of the screen plate 403. To prevent materials from falling from both sides of the screen plate 403, the cross-section of the screen plate 403 is preferably a "︶" structure, that is, the height of the middle part of the screen plate 403 is lower than the height of the two side edges, and the width of the screen plate 403 is greater than the width of the feed hopper 2011.

[0053] The traction mechanism includes a traction rope 405 and a roller 407. One end of the traction rope 405 is fixedly connected to the end of the mesh plate 403. The roller 407 is rotatably connected to the tail end face of the mixing chamber 201 through the frame plate 406. The other end of the traction rope 405 passes through the tail end face of the mixing chamber 201 and is fixedly connected to the roller 407. A traction motor 408 is provided on the side of the frame plate 406. The output shaft of the traction motor 408 is fixedly connected to the end of the roller 407.

[0054] Specifically, during the addition of powder raw materials, the traction motor 408 is started to drive the roller 407 to rotate and wind up the traction rope 405. At the same time, the traction rope 405 drives the end of the screen plate 403 to move horizontally in a straight line, thereby unwinding the screen plate 403. Meanwhile, the falling speed of the powder raw materials into the mixing chamber 201 is adapted to the unwinding speed of the screen plate 403, so that the powder raw materials are evenly distributed on the screen plate 403. At the same time, the spiral spring 404 elastically contracts as the screen plate 403 is unwinded. When the traction end of the screen plate 403 reaches the designated position, there is a gap between it and the inner end face of the mixing chamber 201, and the screen plate 403 is still wound on the roller 402.

[0055] The cleaning unit 5 includes two symmetrically arranged electric slide rails 501. The two electric slide rails 501 are respectively located on both sides of the inner top surface of the mixing chamber 201. The bottom of the sliding part of the electric slide rail 501 is provided with a scraper 502. The scraper 502 is a U-shaped structure that fits against the inner wall of the mixing chamber 201. Both sides of the scraper 502 are provided with inclined surfaces 503.

[0056] Specifically, the electric slide rail 501 drives the scraper 502 to move linearly, and uses the inclined surface 503 on the side of the scraper 502 to scrape and clean the raw materials attached to the inner wall of the mixing chamber 201.

[0057] In operation, the operator installs the fiberglass braided sleeve, inner film, and outer film roll onto the corresponding yarn racks of the unwinding module, threads the material, and passes it through each process unit in sequence. The central control module initializes the parameters of each unit. The fiberglass braided sleeve first enters the closed chamber of the resin impregnation module. The resin pump inside the chamber injects the resin raw material mixed by the raw material mixing module. The sleeve is completely immersed in the resin under the action of the guide roller and pressure roller. Then, it passes through a pair of precision-machined metering scraper rollers to squeeze out excess resin, precisely controlling the resin content. The fully impregnated tube then enters the needle punching module. At the same time, the inner film protective layer is introduced and covers the bottom of the tube. The needle roller rotates at high speed, and the needles penetrate the inner film. The membrane and impregnated fiber layer are intertwined and air bubbles are expelled. Then, the hose enters the pre-curing module and is irradiated with ultraviolet light of a specific wavelength and intensity, causing the surface resin to pre-cur. After that, the hose passes through the online monitoring module, where a beta-ray thickness gauge measures its thickness in real time and transmits the data to the control system. If the thickness deviates from the set value, the central control module will fine-tune the gap of the scraper roller in the impregnation module to restore it to normal. Then, the coating module precisely applies the outer film to the outer surface of the hose. Finally, the completed hose is wound up at constant tension by the fully automatic winding module. When a roll reaches the set length, the winding machine automatically cuts the material strip and switches to an empty reel to continue winding, thus achieving uninterrupted production.

[0058] When the raw material mixing module mixes the raw materials, it starts the drive motor 205 and the heating module. The drive mechanism causes the mounting shafts 202 on both sides to rotate synchronously, so that the mixing blades 203 perform the mixing action first. The heating module maintains the temperature inside the mixing chamber 201. A certain amount of viscous raw material is added into the mixing chamber 201 through the feed hopper 2011. Then, a certain amount of powder raw material is added into the mixing chamber 201 through the feed hopper 2011. At the same time, the traction motor 408 is started to drive the roller 407 to rotate and move the traction rope 405. The winding process causes the end of the screen plate 403 to move towards the winding roller 407 for unwinding, so that the powder material falls evenly onto the surface of the screen plate 403 as it is unwound. After the powder material is fed in, the traction motor 408 is started to rotate in both directions. Under the elastic action of the spiral spring 404, the unfolding section of the screen plate 403 is reciprocated, so that the powder material on the screen plate 403 is evenly sprinkled into the mixing chamber 201 through the mesh on the screen plate 403 and evenly mixed with the continuously agitated viscous material.

[0059] After the visual sensor detects that the powder material on the screen plate 403 has been added, a certain amount of liquid material is pressurized through the external liquid supply system and introduced into the liquid inlet pipe 301. Finally, it is sprayed into the mixing chamber 201 through the nozzle 304. The sprayed liquid material falls onto the screen plate 403 and is further evenly divided into several streams of water by the evenly distributed mesh on the screen plate 403. This allows the liquid material to be evenly dispersed and fall into the bottom of the mixing chamber 201, achieving uniform mixing of the liquid material with other materials in the mixing chamber 201. At the same time, the impact of the liquid material completely removes the powder material remaining on the screen plate 403 and mixes it with other materials at the bottom of the mixing chamber 201 along with the liquid material. After the material injection is completed, the screen plate 403 is completely dry before being wound up.

[0060] After the various raw materials are mixed in the mixing chamber 201 for a specified time, the sealing plate at the bottom of the discharge frame 2012 is opened. The rotation of the spirally arranged mixing blades 203 pushes the material towards the discharge frame 2012 to discharge the mixed material. In order to speed up the discharge of the material, the hydraulic rod 102 is contracted to drive the tail end of the mixing chamber 201 downward, that is, the discharge frame 2012 moves downward, so as to speed up the flow of the material.

[0061] As the material is discharged, the electric slide rail 501 is activated to drive the U-shaped scraper 502 to reciprocate. The inclined surface 503 on the side of the scraper 502 scrapes off the material adhering to the inner wall of the mixing chamber 201, so that the material is completely discharged and prevents the material from condensing on the inner wall of the mixing chamber 201.

[0062] However, while the powder raw materials are evenly sprinkled into the mixing chamber 201 using the horizontal reciprocating motion of the mesh plate 403, some clumps of powder raw materials cannot fall in. Therefore, the following improvements are made:

[0063] The scraper 502 has mounting grooves 504 on both sides of its top edge. Movable seats 505 are slidably connected in the mounting grooves 504. Rotary rollers 506 are rotatably connected between the movable seats 505 on both sides. An electric telescopic rod 507 is provided between the movable seats 505 and the top of the mounting grooves 504.

[0064] Specifically, the rotating roller 506 is located above the screen plate 403 and is adapted to the structure of the screen plate 403. The rotating roller 506 is moved up and down by the extension and retraction of the electric telescopic rod 507 through the movable seat 505 to adjust the height of the rotating roller 506. In the initial state, there is a gap between the rotating roller 506 and the screen plate 403.

[0065] In use, when the vision sensor detects that there is residual lumpy material on the screen plate 403, the electric slide rail 501 is first started to drive the scraper 502 to move. The scraper 502 drives the rotating roller 506 to move along the surface of the screen plate 403. When the rotating roller 506 moves to the vicinity of the lumpy material, the electric telescopic rod 507 is then started to drive the rotating roller 506 to move downward, so that the bottom of the rotating roller 506 is in contact with the surface of the screen plate 403. During the movement of the rotating roller 506, the rotation of the rotating roller 506 can be used to crush and break the lumpy material to eliminate the lumpy material.

[0066] In addition, due to the surface tension of liquids, the mesh of the screen 403 can become clogged as the liquid raw material falls through it into the bottom of the mixing chamber 201. Similarly, the screen 403 can also become clogged when powder raw materials pass through it, preventing the liquid and powder raw materials from falling and affecting the uniformity of mixing. Therefore, the following improvements are made:

[0067] The hybrid leaf 203 is made of ferromagnetic material, and an electromagnetic sheet 409 is embedded on the bottom surface of the mesh plate 403. The electromagnetic sheet 409 generates magnetism after being energized and cooperates with the ferromagnetic hybrid leaf 203.

[0068] During use, as the powder and liquid raw materials fall into the mixing chamber 201 through the mesh plate 403, if, after a specified time, the visual sensor detects that a significant amount of powder or liquid raw material remains on the mesh plate 403, it will automatically determine that the mesh plate 403 is blocked. At this time, the electromagnetic plate 409 is energized and generates magnetism. Since the mixing blade 203 is made of ferromagnetic material, when the mixing blade 203 rotates and aligns with the electromagnetic plate 409 at the bottom of the mesh plate 403, the magnetic attraction will cause the corresponding electromagnetic plate 409 to move. 09 drives a local area of ​​the screen plate 403 to move slightly downward, thereby using the continuous rotation of the mixing blade 203 to achieve vibration of the screen plate 403. At the same time, the electric telescopic rod 507 drives the rotating roller 506 to move up and down reciprocally. When the rotating roller 506 moves downward, it impacts the surface of the screen plate 403, causing the screen plate 403 to vibrate in the vertical direction, which can remove the powder or liquid material blocked in the mesh of the screen plate 403. After the removal is completed, the electromagnetic plate 409 and the electric telescopic rod 507 stop working and continue to feed material.

[0069] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
