Description

Technical Field

[0001] The invention relates to the technical field of glue injection equipment, and in particular to automatic glue injection equipment for processing UV-CIPP lined hoses. Background Art

[0002] UV-CIPP lining hose is a material used for trenchless pipe repair. It is a hose impregnated with photosensitive resin, which can be quickly cured under ultraviolet light to form a new lining pipe inside the old pipe, which plays a role in repairing and reinforcing the original pipe.

[0003] The UV-CIPP lined hose consists of an inner layer, a resin layer and an outer layer. The inner and outer layers are usually made of special polyester fibers or glass fiber fabrics. These fiber materials provide the lined hose with basic strength and toughness, and can withstand certain internal pressures and external loads. The resin layer is the key part of the UV-CIPP lined hose. The resin is generally a photosensitive resin. In the uncured state, it can keep the hose soft and bendable, making it easy to pull or flip it into the old pipe to be repaired. When exposed to ultraviolet rays, the resin will undergo a polymerization reaction and cure quickly.

[0004] Glue injection is an important step in the processing of UV-CIPP lined hoses. The resin glue is filled into the gap between the inner and outer layers through the glue injection head. After the filling is completed, the hose is transferred to the roller for glue rolling. The current filling operation is mostly double-head synchronous glue injection. This glue injection method takes a long time for the glue to be discharged to the middle, and the glue injection time is long. At the same time, the glue is easy to gather at both ends, and the glue distribution is not uniform. Summary of the invention

[0024] The present invention provides an automatic glue injection device for processing UV-CIPP lined hose. Compared with the prior art, it has the following beneficial effects:

[0025] 1. During processing, a three-point glue injection method is adopted. The glue injection components at both ends can inject glue into the lining hose from both ends. The middle glue injection hole can be opened in the middle of the lining hose by using the punching component. The glue can be injected into the lining hose through the middle glue injection hole through the middle glue injection component. In this way, three-point rapid glue injection is realized, which can effectively improve the glue injection efficiency and the uniformity of glue liquid distribution;

[0026] 2. During three-point glue injection, the glue liquid mostly gathers at the glue injection port, and the filling speed of the main part of the lining hose is affected to a certain extent. To solve this problem, an end glue injection assembly is designed to lift the end of the lining hose, and the second driving rod can drive the guide wheel to move upward to lift the middle part of the lining hose, so that the lining hose forms a W shape. The glue liquid injected at the three points can be quickly dispersed and flowed to the main part of the lining hose under the action of gravity;

[0027] After the glue injection of the main part is completed, the end glue injection assembly and the guide wheel can be gradually lowered, so that the glue liquid gradually gathers at the three-point glue injection position, and the main part will not be over-injected;

[0028] 3. When the glue is injected in the middle, the glue is easy to overflow. During the transportation process, if the glue injection hole in the middle is exposed, the glue is easy to be exposed and the glue is attached with dust. In order to solve the above problems, a closed liquid guide sticker is provided. The closed liquid guide sticker can be used as a closed liquid guide structure during glue injection, so that the glue can accurately pass through the middle glue injection hole into the inner and outer layers of the lining hose to avoid overflow. After the glue injection is completed, the closed liquid guide sticker can quickly close the middle glue injection hole to avoid the glue overflow during transportation. At the same time, when the closed liquid guide sticker is closed, the lining hose can be flat, which will not affect the subsequent glue rolling work;

[0029] 4. During the transfer, if both ends of the lining hose are open, glue will overflow from the ends of the lining hose during the transfer process. To solve the above problem, the end closing component is designed to automatically clamp the closing splint at the end of the lining hose to achieve automatic closing. When rolling the glue later, you only need to open the closing splint at one end to allow the excess glue to be discharged stably. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described.

[0047] An end glue injection assembly 2 is installed at the outer end of each group of conveyor belts 11. The end glue injection assembly 2 includes a transverse guide rail 21. A first support tube 22 is vertically slidably installed inside the transverse guide rail 21. A first support rod 23 is vertically slidably installed inside the first support tube 22. A first driving rod 24 for driving the first support rod 23 to rise and fall is provided on the side wall of the first support tube 22. A glue injection component 26 is provided on the top of the outer end of the first support rod 23, and a closed clamping jaw 25 is provided on the bottom of the outer end. The closed clamping jaw 25 is used to clamp and position the end outer wall of the lining hose. The glue injection component 26 is used to inject glue into the gap between the two layers of the lining hose from both ends.

[0048] An end closing assembly 3 is installed at the outer end of each conveyor belt 11. The end closing assembly 3 is installed at the outer side of the glue injection component 26. The end closing assembly 3 is used to clamp the closing clamp 4 at the end of the liner hose after the glue injection.

[0049] A punching assembly 5 is disposed on the side of the transfer conveying component, and is used to open a middle glue injection hole in the middle of the upper surface of the lining hose;

[0050] A closed liquid-conducting patch 6 is bonded to the middle glue injection hole. The closed liquid-conducting patch 6 is used to unidirectionally seal the glue injection when the liner hose is injected with glue, and to flushly seal the middle glue injection hole when the liner hose is transferred;

[0051] The middle glue injection component 7 is placed on the side of the transfer conveying component. The output end of the middle glue injection component 7 is connected to the closed liquid guide patch 6. The middle glue injection component 7 is used to inject glue from the middle glue injection hole into the gap between the two layers of the lining hose to improve the glue injection speed and glue injection uniformity of the lining hose.

[0052] In the early and middle stages of the automatic glue injection equipment, the end glue injection assembly 2 lifts up the two ends of the lining hose, and the transfer guide component 12 lifts up the middle of the lining hose, so that the glue injected in the middle and the two ends quickly flows to the main body parts on both sides of the lining hose;

[0053] In the later stage of glue injection, the end glue injection assembly 2 moves outward and descends, and the middle guide component descends, so that the lining hose is gradually flattened, and the glue can flow to the end and the middle.

[0054] In the above scheme:

[0055] 1. During processing, a three-point glue injection method is adopted. The glue injection components at both ends can inject glue into the lining hose from both ends. The middle glue injection hole can be opened in the middle of the lining hose by using the punching component. The glue can be injected into the lining hose through the middle glue injection hole through the middle glue injection component. In this way, three-point rapid glue injection is realized, which can effectively improve the glue injection efficiency and the uniformity of glue liquid distribution;

[0056] 2. During three-point glue injection, the glue liquid mostly gathers at the glue injection port, and the filling speed of the main part of the lining hose is affected to a certain extent. To solve this problem, an end glue injection assembly is designed to lift the end of the lining hose, and the second driving rod can drive the guide wheel to move upward to lift the middle part of the lining hose, so that the lining hose forms a W shape. The glue liquid injected at the three points can be quickly dispersed and flowed to the main part of the lining hose under the action of gravity;

[0057] After the glue injection of the main part is completed, the end glue injection assembly and the guide wheel can be gradually lowered, so that the glue liquid gradually gathers at the three-point glue injection position, and the main part will not be over-injected;

[0058] 3. When the glue is injected in the middle, the glue is easy to overflow. During the transportation process, if the glue injection hole in the middle is exposed, the glue is easy to be exposed and the glue is attached with dust. In order to solve the above problems, a closed liquid guide sticker is provided. The closed liquid guide sticker can be used as a closed liquid guide structure during glue injection, so that the glue can accurately pass through the middle glue injection hole into the inner and outer layers of the lining hose to avoid overflow. After the glue injection is completed, the closed liquid guide sticker can quickly close the middle glue injection hole to avoid the glue overflow during transportation. At the same time, when the closed liquid guide sticker is closed, the lining hose can be flat, which will not affect the subsequent glue rolling work;

[0059] 4. During the transfer, if both ends of the lining hose are open, glue will overflow from the ends of the lining hose during the transfer process. To solve the above problem, the end closing component is designed to automatically clamp the closing splint at the end of the lining hose to achieve automatic closing. When rolling the glue later, you only need to open the closing splint at one end to allow the excess glue to be discharged stably.

[0060] In this embodiment, the glue injection component 26 includes a main matching tube 261 and an inner clamping component 27. The inner bottom of the main matching tube 261 is provided with an annular outer cavity 262 and an inner cavity 263. The outer cavity 262 is located on the outside of the inner cavity 263. The bottom of the outer cavity 262 is connected to a glue injection channel 2621, and the bottom of the inner cavity 263 is connected to an exhaust channel 2631. The side of the inner cavity 263 is connected to a vacuum pump, which is used to extract the air between the inner and outer layers of the lining hose to reduce the injection of bubbles. The inner clamping component 27 is installed inside the main matching tube 261. The outer layer 91 of the lining hose is placed between the closed jaws 25 and the main matching tube 261, and the inner layer 92 of the lining hose is placed between the main matching tube 261 and the inner clamping component 27.

[0061] In the above scheme:

[0062] The closed jaws arranged on the left and right are designed to cooperate with the outer wall of the main matching tube, so as to clamp and position the outer layer of the lining hose. The closed jaws are semicircular, and the inner clamping parts are designed to cooperate with the inner wall of the lining hose, so as to clamp and position the inner layer of the lining hose. In this way, the end of the lining hose is positioned. The main matching tube is designed to have an inner cavity and an outer cavity. The air between the inner and outer layers can be extracted by using the inner cavity and the exhaust channel. In this way, the glue can flow more smoothly and reduce gas obstruction during glue injection. It can also eliminate residual bubbles in the glue being filled to ensure the compactness of the glue. In this embodiment, the inner clamping component 27 includes a positioning plate 271, a third driving rod 272, a sliding rod 273, an upper ring body 274, a lower seat body 275, a rocker rod 276 and an inner clamping plate 277. The positioning plate 271 is arranged at the inner top of the main matching tube 261, and a sliding rod 273 is vertically provided in the middle of the bottom surface of the positioning plate 271. The outer wall of the sliding rod 273 is slidably provided with an upper ring body 274, and the bottom end of the sliding rod 273 is provided with a lower seat body 275. The interior of the lower seat body 275 is horizontally slidably embedded with inner clamping plates 277 arranged in a circular array. The top end of the rocker rod 276 is rotatably connected to the upper ring body 274, and the bottom end is rotatably connected to the top of the inner clamping plate 277. The third driving rod 272 is vertically arranged on the bottom surface of the positioning plate 271, and the output end of the third driving rod 272 is connected to the upper ring body 274; the inner clamping plate 277 is used to clamp and position the inner layer of the lining hose from the inside.

[0063] In the above scheme: when clamping internally, the third driving rod drives the upper ring body to move downward, and the upper ring body drives the inner clamping plate to extend from the lower seat body through the sliding rod, and the inner clamping plate can clamp and position the inner layer of the lining hose from the inside.

[0064] In this embodiment, the end closing component 3 includes a second support rod 31, a bidirectional screw seat 32, and a moving block 33. The second support rod 31 is fixedly arranged on the side of the end of the conveyor belt 11. The top of the second support rod 31 is provided with a bidirectional screw seat 32. The opening and closing end of the bidirectional screw seat 32 faces the end glue injection component 2. The moving block 33 is symmetrically and slidably installed on the side of the bidirectional screw seat 32. The external assembly of the two groups of moving blocks 33 is connected to the closed clamp 4. The bidirectional screw seat 32 is used to drive the closed clamp 4 to clamp the end of the closed liner hose.

[0065] In the above scheme: in the later stage of glue injection, the first support tube moves outward along the horizontal guide rail. At the same time, the first driving rod drives the first support rod to gradually descend. When the glue injection is completed, the closing jaw moves to the top of the closing splint, and the end of the hose is vertically placed in the closing splint. Then the bidirectional screw seat drives the moving seat to move inward, so that the closing splint is closed. The closing splint can clamp and position the end of the lining hose. After the sealing is completed, the worker lifts the end of the lining hose, so that the inner baffle and the outer baffle are lifted up and separated from the moving block.

[0066] In this embodiment, the closed clamping plate 4 includes a first side clamping plate 41, a second side clamping plate 42, an outer baffle plate 43 and an inner baffle plate 44. The inner ends of the first side clamping plate 41 and the second side clamping plate 42 are both provided with a clamping block 49. The end surface of the movable block 33 is provided with a clamping groove that cooperates with the clamping block 49. The interior of the first side clamping plate 41 is symmetrically provided with a first positioning hole 411 and a second positioning hole 412; the outer baffle plate 43 is rotatably installed on the outer end of the inner wall of the second side clamping plate 42 and a torsion spring is installed at the rotating connection. The outer baffle plate 43 can only rotate inward, and the outer baffle plate 43 is relatively matched and clamped with the first positioning hole 411; the inner end of the inner wall of the second side clamping plate 42 is vertically provided with an inner baffle plate 44, and the inner baffle plate 44 is relatively matched and clamped with the second positioning hole 412.

[0067] In the above scheme:

[0068] When injecting glue, workers can relatively pre-insert the first side clamp and the second side clamp into the moving block, and vertically insert the clamping block into the clamping slot; the inner baffle and the outer baffle are designed to position the lining hose left and right, and the outer baffle is designed to be able to rotate only inward, so that the lining hose can smoothly enter between the inner baffle and the outer baffle, and the torsion spring can drive the outer baffle to rotate outward and reset after the lining hose enters; when the two groups of moving blocks move inward, the first side clamp and the second side clamp can clamp and position the lining hose, and the inner baffle and the outer baffle can be relatively inserted into the corresponding positioning holes to achieve clamping positioning.

[0069] In this embodiment, the outer side surfaces of the inner baffle plate 44 and the outer baffle plate 43 are both provided with matching bevel racks 45, and the sides of the first positioning hole 411 and the second positioning hole 412 are both provided with accommodating grooves 48, and a rotating shaft 46 is horizontally rotatably installed inside the accommodating groove 48, and the end of the rotating shaft 46 is exposed to the first side clamping plate 41, and a spring rod 461 is vertically provided on the side wall of the rotating shaft 46, and an abutting bevel tooth 47 is provided on the outer end of the spring rod 461; when the closed clamping plate 4 is locked, the abutting bevel tooth 47 abuts against the matching bevel rack 45 to prevent the matching bevel rack 45 from being disengaged from the first positioning hole 411 or the second positioning hole 412; when the closed clamping plate 4 is unlocked, the outer end of the rotating shaft 46 is rotated to make the abutting bevel tooth 47 rotate upward to disengage from the matching bevel rack 45, and the second side plate body can be separated from the first side plate body.

[0070] In the above scheme: when the inner baffle plate and the outer baffle plate are inserted, the matching bevel rack can gradually squeeze the resisting bevel gear, and the resisting bevel gear squeezes the spring rod at the rear end to ensure that the inner baffle plate and the outer baffle plate can be inserted. After the insertion is completed, the resisting bevel gear can resist the matching bevel rack from the rear end to prevent the inner baffle plate and the outer baffle plate from falling off. When separation is required later, the outer end of the rotating shaft can be rotated to drive the resisting bevel gear to rotate upward and disengage from the matching bevel gear. In this way, the inner baffle plate and the outer baffle plate can be pulled out and the closed splint can be recycled.

[0071] In this embodiment, the closed liquid-conducting patch 6 includes a lower body 61, an upper body 62, a one-way joint 63 and a closing film 64. The lower body 61 is bonded to the middle glue injection hole of the lining hose. A lower through hole 611 is provided at a position relative to the middle glue injection hole of the lower body 61. A one-way joint 63 is installed on the surface of the upper body 62. The one-way joint 63 is arranged opposite to the lower through hole 611. A closing film 64 is provided on the side of the lower body 61. After the glue injection is completed, the upper body 62 is torn off, and the closing film 64 is bent and fitted on the lower body 61 to close the lower through hole 611.

[0072] In the above scheme:

[0073] The closed liquid-conducting sticker is designed to have an upper and lower two-layer structure. When fitting, the closed liquid-conducting sticker is fitted on the middle glue injection hole as a whole. The one-way valve can be used as a reserved structure to facilitate docking with the middle glue injection component, so that the glue can smoothly enter the gap of the lining hose; the closing film is reserved on the side of the lower sticker at this time for subsequent sealing; after the glue injection is completed, the operator only needs to tear off the upper sticker, and the glue remaining on the lower sticker, and the closing film can be bent and fitted on the lower sticker. In this way, the lower perforation can be quickly closed, the middle glue injection hole can be closed, and the surface of the lining hose can be made nearly flush. In this embodiment, the middle glue injection assembly 7 includes a third support rod 71, a fourth drive rod 72, a bottom plate 73, and a glue injection tube 74. The top of the third support rod 71 is provided with a fourth drive rod 72 vertically downward, the bottom end of the fourth drive rod 72 is vertically connected to the bottom plate 73, and a glue injection tube 74 is provided at one end of the bottom surface of the bottom plate 73; the one-way joint 63 includes an outer shell 631, and the interior of the outer shell 631 is provided with an upper ring groove 6311, a middle ring groove 6312 and a lower ring groove 6313 from top to bottom. The inner diameters of the middle ring groove 6312, the upper ring groove 6311 and the lower ring groove 6313 increase in sequence, and the middle ring groove 6312 increases in sequence. A positioning frame 632 is provided at the inner bottom, a pressure rod 633 is vertically slidably installed in the middle of the positioning frame 632, a spring 634 is sleeved on the outside of the pressure rod 633, a pressure plate 6331 is provided at the top of the pressure rod 633, the spring 634 is arranged between the pressure plate 6331 and the positioning frame 632, a sealing plate 6332 is provided at the bottom end of the pressure rod 633, and the sealing plate 6332 is used to block the middle ring groove 6312; a resistance rod 741 is provided at the inner bottom end of the glue injection tube 74, the glue injection tube 74 is inserted into the upper ring groove 6311, the resistance rod 741 resists the pressure rod 633, so that the sealing plate 6332 moves downward and disengages from the middle ring groove 6312.

[0074] In the above scheme: when the glue injection is connected, the fourth driving rod drives the bottom plate to descend, so that the glue injection tube is inserted into the upper ring groove, the resistance rod presses the pressure plate downward, so that the pressure rod moves downward along the positioning frame, the pressure plate presses down the spring, and the sealing plate descends and disengages from the middle ring groove. Subsequently, the external glue supply box passes the glue liquid through the glue injection tube and the one-way valve into the gap of the lining hose; when the glue injection is completed, the spring drives the sealing plate to seal the middle ring groove to prevent the glue liquid from overflowing.

[0075] In this embodiment, the punching assembly 5 includes a fourth support rod 51, a second support tube 54 arranged horizontally is vertically provided at the top of the fourth support rod 51, a fifth support rod 55 is slidably installed inside the second support tube 54, a fifth driving rod 53 for driving the fifth support rod 55 to extend and retract is provided at the top of the second support tube 54, a drill bit 56 is installed on the bottom surface of the outer end of the fifth support rod 55, a sixth driving rod 57 arranged vertically downward is provided on the outer end of the fifth support rod 55, a hanging plate 58 is provided at the bottom end of the sixth driving rod 57, and an adsorption head 59 is symmetrically provided on the bottom surface of the hanging plate 58.

The adsorption heads 59 are connected to the negative pressure fan 52 through the hose. After adsorption and lifting, the drill bit 56 opens a middle glue injection hole in the outer layer 91 of the lining hose 9.

[0076] In the above scheme, when drilling, the glue injection tube is lifted up, and the fifth driving rod drives the fifth supporting rod to move outward, so that the suction head contacts the upper surface of the lining hose, and the negative pressure fan works to generate negative pressure at the suction head. The suction head can then adsorb the outer layer of the lining hose, and the sixth driving rod drives the hanging plate to lift up, so that the suction head can adsorb the outer layer and move upward. The drill bit rotates, so as to drill a middle glue injection hole in the lifted outer layer, thereby realizing fast, accurate and automatic drilling operations.

[0077] In order to further speed up the flow of glue to the main part and increase uniformity, the following solution is given:

[0078] In this embodiment, glue-driving components 8 are installed at the four corners of the lining hose, and the glue-driving components 8 include a constraint plate 81, and a rectangular movable groove 811 is opened on the outer wall of the constraint plate 81, and a slider 812 is slidably embedded in the movable groove 811. A connecting shaft 821 is provided on the outer wall of the slider 812, and the outer end of the connecting shaft 821 is connected to a rolling column 82. A driving shaft 83 is installed in the middle of the constraint plate 81, and a driving arm 84 is vertically provided on the side of the driving shaft 83. The driving arm 84 is parallel to the side of the constraint plate 81, and a movable groove 841 is opened on the outer end of the driving arm 84, and the connecting shaft 821 slides through the movable groove 841; when the driving shaft 83 drives the rolling column 82 to move, the rolling column 82 will move along the bending part of the lining hose to flatten the glue liquid to the main body.

[0079] In the above scheme: by designing four groups of glue-driving components, each bend corresponds to a group of glue-driving components. When the driving shaft drives the driving arm to rotate, the driving arm drives the moving block to move along the moving groove through the internal connecting shaft, and then drives the rolling column to move along the bend of the lining hose, thereby realizing glue-driving and allowing the glue liquid to be quickly discharged.
