Description

Technical Field

[0001] This utility model relates to the field of light-curing hose production technology, specifically to an automated production line for light-curing hoses. Background Technology

[0002] Currently, the automation of trenchless UV-curing repair hose production is not yet realized in China. In conventional trenchless UV-curing repair hose production, the laying of the fabric, the layering and stacking of the hose, and the packing are all done manually. Fabric laying is mostly done by manually rolling the fabric roll to lay a single layer flat before laying the next layer, and so on. Hose forming is also done manually, layer by layer. Packing is mostly done manually by pushing and pulling the hoses together. Manual production of UV-curing hoses is labor-intensive, inefficient, and prone to significant deviations in fabric placement, affecting product quality. It also requires multiple people to complete, resulting in low efficiency and high cost. Therefore, the development of an automated production line for UV-curing hoses has become a new challenge for technicians in my country's trenchless UV-curing repair hose equipment manufacturing industry.

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0048] Reference Figures 1-2As shown, an automated production line for photocurable flexible tubes includes a fabric rack assembly I, a forming assembly II, a sewing device, and a packing assembly III fixed on a foundation. Multiple layers of fabric and inner film are stacked in the fabric rack assembly I to form a multi-layer flat fabric 2. After passing through the forming assembly II, the two ends of the multi-layer flat fabric 2 are folded upwards to form folded portions. The opposite ends of the two folded portions of the multi-layer flat fabric 2 are sewn together by the sewing device to form a flexible tube 5. The flexible tube 5 is then packed into a packing assembly III.

[0049] Reference Figures 3-5 As shown, the fabric rack assembly I includes a frame 10. Multiple side supports 11 are fixed at both ends of the frame 10. Two first supports 12 are fixed at the lower end of one side of the frame 10. The two first supports 12 are rotatably connected to the first rotating roller 21. Two second supports 13 are fixed at the upper end of one side of the frame 10. The two second supports 13 are rotatably connected to the second rotating roller 22. The second rotating roller 22 corresponds vertically to the first rotating roller 21. Multiple winding components are fixed on the frame 10. The multiple winding components are staggered.

[0050] The winding assembly includes two fourth supports 17 and a fourth roller 23. The two fourth supports 17 support both ends of the fourth roller 23, and both ends of the fourth roller 23 can rotate within the two fourth supports 17 respectively. Two third supports 14 are fixed on one side of the upper end of the frame 10, and the two third supports 14 support both ends of the third roller 20, and both ends of the third roller 20 can rotate within the two third supports 14 respectively. The third roller 20 is close to the second roller 22 and located below the second roller 22. The first roller 21, the second roller 22, the third roller 20 and the fourth roller 23 are parallel. A fifth roller 24 corresponding to the fourth roller 23 is rotatably arranged in the lower end of the frame 10. The fifth roller 24 is parallel to the first roller 21, and the lower end of the fifth roller 24 is flush with the lower end of the first roller 21.

[0051] Multiple fabric rolls 16 are respectively mounted on multiple fourth rollers 23. The free end of the fabric passes over the lower end of a fifth roller 24 and is located below the first roller 21. The inner film roll 15 is mounted on the third roller 20. The free end of the inner film passes over the upper end of the second roller 22 and the lower end of the first roller 21 in sequence. The inner film is located at the upper end of the multi-layer fabric below the first roller 21.

[0052] The fifth roller 24 is rotatably connected to the fifth support 18 at both ends, and the fifth support 18 is fixed inside the lower end of the frame 10. The inner film portion between the first roller 21 and the inner film roll 15 is filled with air. The inner film portion between the first roller 21 and the inner film roll 15 expands and forms a storage cavity inside. A traction coil 19 is placed in the storage cavity. The free end of the traction coil 19 passes through the free end of the inner film. Two collars 25 are fitted on the first roller 21, the second roller 22, the third roller 20, the fourth roller 23 and the fifth roller 24. A positioning screw 26 is threaded onto the collar 25.

[0053] In use, multiple fabric rolls 16 are respectively fitted onto multiple fourth rollers 23, and the inner film roll 15 is fitted onto the third roller 20. At this time, the multiple fabric rolls 16 correspond one-to-one with the multiple fifth rollers 24. The free end of the fabric passes over one fifth roller 24 and then passes under the first roller 21. The fabric under the first roller 21 forms a flat fabric 2. Multiple layers of flat fabric 2 are stacked under the first roller 21. Then, the free end of the inner film passes over the upper end of the second roller 22, and air is filled into the inner film portion between the second roller 22 and the inner film roll 15 through the free end of the inner film. The inner film portion between the first roller 21 and the inner film roll 15 expands and the inner film... The inner membrane roll 15 forms a storage cavity, and the traction coil 19 is placed into the storage cavity, so that the free end of the traction coil 19 passes through the free end of the inner membrane. Then, the free end of the inner membrane and the free end of the traction coil 19 pass around the lower end of the first roller 21 and are located at the upper end of the multi-layer flat fabric 2. When the free ends of the fabric, the free ends of the inner membrane and the free ends of the traction coil 19 are pulled, the inner membrane portion between the inner membrane roll 15 and the second roller 22 is always in an expanded state. During the process of the inner membrane winding out, the traction coil 19 is always unwound in the storage cavity.

[0054] By setting the collars 25, the positions of the two collars 25 on the first rotating roller 21 can be adjusted. The two collars 25 on the first rotating roller 21 can limit the multi-layer fabric below the first rotating roller 21. Adjusting the positions of the two collars 25 on the second rotating roller 22 can limit the inner film. Adjusting the positions of the two collars 25 on the fifth rotating roller 24 can limit the fabric. The two collars 25 on the fourth rotating roller 23 can limit the fabric roll 16. The two collars 25 on the third rotating roller 20 can limit the inner film roll 15.

[0055] The multi-layer flat fabric 2 and the inner membrane are pulled out from the fabric frame assembly I and then enter the molding assembly II.

[0056] Reference Figures 6-11 As shown, the molding assembly II includes a conveying component 1 for pushing the multi-layer flat fabric 2 and a folding component 3 for folding the multi-layer flat fabric 2 into layers. The folding component 3 is located above the conveying component 1 and is fixedly connected to the conveying component 1.

[0057] The fabric stacking assembly 3 includes multiple fabric stacking units. The number of fabric stacking units is equal to the number of layers of the flat fabric 2. The multiple fabric stacking units are arranged sequentially in the conveying direction of the conveying assembly 1. The multiple fabric stacking units correspond one-to-one with the multiple layers of flat fabric 2 in the vertical direction.

[0058] During the process of conveying the multi-layer flat fabric 2 by the conveying component 1, multiple stacking units can fold the multi-layer flat fabric 2 from top to bottom.

[0059] The fabric stacking unit includes two fabric stacking supports 301. The lower end of the fabric stacking support 301 is fixedly connected to the conveying component 1. The two fabric stacking supports 301 are symmetrically arranged front and back. Each fabric stacking support 301 is provided with a guide component. The two guide components of the fabric stacking unit are staggered in the left and right direction. The projection of the front guide component backward is symmetrical to the rear guide component.

[0060] It also includes a core mold assembly 4, which is located above the conveying assembly 1 and is fixedly connected to the conveying assembly 1. The core mold assembly 4 is located in front of the fabric stacking assembly 3.

[0061] The conveying assembly 1 includes a frame 106 mounted on a foundation. The lower end of a fabric stacking bracket 301 is fixedly connected to the upper end of the frame 106. A first conveyor belt tensioning roller 101 is mounted on the front end of the frame 106, and a first conveyor belt drive roller 107 is mounted on the rear end of the frame 106. A first conveyor belt 102 is mounted on the first conveyor belt tensioning roller 101 and the first conveyor belt drive roller 107. A lower conveyor belt idler roller 103 is mounted on the underside of the frame 106 to prevent flatness below the first conveyor belt 102. The first conveyor belt 102 is suspended downwards. The conveyor belt support roller 104 is installed on the upper part of the frame 106 to support the straight part above the first conveyor belt 102. The conveyor belt support plate 105 is installed between the conveyor belt support rollers 104 and is fixedly connected to the frame 106. The conveyor belt support plate 105 supports the straight part above the first conveyor belt 102. The first motor 108 is installed on the frame 106 below the first conveyor belt drive wheel 107 and is connected to the first conveyor belt drive wheel 107 for transmission.

[0062] The guiding component includes a fixed frame 302 fixed on the fabric stacking bracket 301. Multiple light rods 304 are slidably arranged in the left and right directions of the fixed frame 302. The light rods 304 are fixedly connected to the sliding frame 303. A lead screw 305 is rotatably connected to the fixed frame 302. The lead screw 305 passes through the sliding frame 303 and is threadedly connected to the sliding frame 303. A second motor 306 is fixed on the fixed frame 302. The second motor 306 can drive the lead screw 305 to rotate. A fabric stacking template 307 is fixed at the front end of the sliding frame 303. The heights of the two fabric stacking templates 307 on the same fabric stacking unit are equal. In two adjacent fabric stacking units, the height of the fabric stacking template 307 of the front fabric stacking unit is greater than the height of the fabric stacking template 307 of the rear fabric stacking unit.

[0063] The front end of the fabric folding template 307 is curved upwards on the side away from the middle position of the first conveyor belt 102 to form an arc-shaped part 3073. The rear end of the fabric folding template 307 is bent upwards on the side away from the middle position of the first conveyor belt 102 to form an upper straight part 3072. The part of the fabric folding template 307 below the arc-shaped part 3073 and the upper straight part 3072 forms a lower straight part 3071. The upper straight part 3072 is parallel to the lower straight part 3071. The upper straight part 3072 and the arc-shaped part 3073 are connected to the lower straight part 3071 in an arc transition. The arc-shaped part 3073 is connected to the upper straight part 3072 in an arc transition.

[0064] The core mold assembly 4 includes a fixed bracket 402, the lower end of which is fixedly connected to the upper end of the frame 106. A flat plate 401 is fixed inside the lower end of the fixed bracket 402. The flat plate 401 is horizontally arranged and corresponds to the multi-layer flat fabric 2 placed on the first conveyor belt 102.

[0065] When the molding assembly II is working, the multi-layer flat fabric 2 and the inner film are placed above the front end of the first conveyor belt 102, so that the inner film corresponds to the flat plate 401.

[0066] For ease of description, the multiple overlapping fabric units from front to back are respectively the first overlapping fabric unit, the second overlapping fabric unit, the third overlapping fabric unit... the Nth overlapping fabric unit; the multiple layers of flat fabric from top to bottom are the first layer of fabric, the second layer of fabric, the third layer of fabric... the Nth layer of fabric.

[0067] During the process of the first conveyor belt 102 conveying the multi-layer flat fabric 2 and the inner membrane from front to back, when the rear end of the multi-layer flat fabric 2 and the rear end of the inner membrane move to below the front end of the flat plate 401, the right-side stacking template 307 in the first stacking unit guides the right side of the first layer of fabric. Then, the left-side stacking template 307 in the first stacking unit guides the left side of the first layer of fabric. After the first layer of fabric passes through the left-side and right-side stacking templates 307 in the first stacking unit, the left and right sides of the first layer of fabric form the first left fold and the first right fold, respectively. The first left fold and the first right fold are both located above the middle part of the first layer of fabric. At this time, the flat plate 401 is located inside the first layer of fabric.

[0068] As the first conveyor belt 102 moves, the right-side fabric template 307 in the second fabric stacking unit guides the right side portion of the second layer of fabric. Then, the left-side fabric template 307 in the second fabric stacking unit guides the left side portion of the second layer of fabric. After the second layer of fabric passes through the left-side and right-side fabric templates 307 in the second fabric stacking unit, the left and right sides of the second layer of fabric form a second left fold and a second right fold, respectively. The second left fold of the second layer of fabric is located outside the first left fold of the first layer of fabric, and the second right fold of the second layer of fabric is located outside the first right fold of the first layer of fabric. At this time, the second layer of fabric partially surrounds the outside of the first layer of fabric.

[0069] The multi-layered flat fabric 2 can be folded sequentially through multiple overlapping units. After being folded, the multi-layered flat fabric 2 is sewn together to form a flexible tube 5.

[0070] When the two fabric folding templates 307 of the second fabric fold the left and right sides of the second fabric, the first fabric after the left and right sides are folded becomes the core mold of the second fabric.

[0071] After the second motor 306 is started, the lead screw 305 rotates. During the rotation of the lead screw 305, the position of the sliding frame 303 and the folding template 307 in the left and right directions can be adjusted. Therefore, this forming assembly II can fold flat fabric 2 of different widths.

[0072] like Figure 9 As shown, when one side of the flat fabric 2 enters the corresponding folding template 307, under the guidance of the arc-shaped part 3073, one side of the flat fabric 2 bends upward in an arc shape. Then, the curved part of the flat fabric 2 continues to be guided by the upper straight part 3072. The part of the flat fabric 2 that bends upward in an arc shape eventually bends to be parallel to the middle part of the flat fabric 2 and forms a fold.

[0073] Then the hose 5 enters the packing assembly III for packing.

[0074] Reference Figures 12-14 As shown, the packing assembly III includes a lifting assembly 6 for lifting the hose 5, a pressure roller assembly 7 for increasing the lifting force of the hose 5, and a moving platform assembly 8 for reciprocating folding and packing the hose 5.

[0075] The lifting assembly 6 includes a lifting frame 601 mounted on a foundation, an anti-deviation adjustment roller 602 mounted on the front end face of the lifting frame 601, a second conveyor belt tensioner 603 mounted on the lower end of the lifting frame 601, a second conveyor belt drive wheel 607 mounted on the top end of the lifting frame 601, a second conveyor belt 604 mounted on the second conveyor belt tensioner 603 and the second conveyor belt drive wheel 607, and a drive motor 609 mounted on the lifting frame 601 below the second conveyor belt drive wheel 607. 609 is connected to the second conveyor belt drive wheel 607 for transmission; the pressure roller assembly 7 includes a pressure roller bracket 701, which is fixed on the lifting frame 601. Pressure roller connectors 702 are slidably installed at both ends of the pressure roller bracket 701. The two pressure roller connectors 702 are connected through a pressure roller 704. The pressure roller 704 is rotatably connected to the pressure roller connector 702. A lifting mechanism 703 is fixed at the upper end of the pressure roller bracket 701 above the pressure roller connector 702. The lifting end of the lifting mechanism 703 is connected to the pressure roller connector 702.

[0076] The mobile platform assembly 8 includes a platform base 801, which is mounted on a foundation. Linear guide rails 802 are mounted on both sides of the platform base 801. A movable pallet 803 is mounted on the sliders of the two linear guide rails 802. A ball screw 804 is mounted on a screw support 805, which is fixed to the platform base 801. The nut seat on the ball screw 804 is fixedly connected to the movable pallet 803. A platform motor 806 is fixed to the platform base 801 and is connected to the ball screw 804 through an angle transmission box.

[0077] The lower pressure roller 605 of the conveyor belt is installed on the belly of the lifting frame 601 to prevent the second conveyor belt 604 below the second conveyor belt tensioner 603 and the second conveyor belt drive wheel 607 from interfering with the pressure roller 704;

[0078] The packing guide wheel 608 is installed at the outlet end of the lifting frame 601;

[0079] The pressure roller motor 705 is installed at the upper middle part of the pressure roller bracket 701, and the output shaft of the pressure roller motor 705 is connected to the input shaft of the two lifting machines 703 through a transmission assembly.

[0080] The upper idler roller 606 of the conveyor belt is installed on the upper inclined surface of the lifting frame 601 to support the lower end face of the second conveyor belt 604 portion above the second conveyor belt tensioner 603 and the second conveyor belt drive wheel 607.

[0081] When packing the hose 5, start the pressure roller motor 705. The pressure roller motor 705 rotates in the forward direction. The pressure roller motor 705 drives two elevators 703 simultaneously through the transmission assembly. After the two elevators 703 start, the two pressure roller connectors 702 and the pressure roller 704 move upward at the same time. After the pressure roller 704 moves upward, one end of the hose 5 is located between the pressure roller 704 and the second conveyor belt 604.

[0082] Then start the pressure roller motor 705. The pressure roller motor 705 rotates in the opposite direction. The pressure roller motor 705 drives the two lifts 703 simultaneously through the transmission component. After the two lifts 703 start, the two pressure roller connectors 702 and the pressure roller 704 move down at the same time. After the pressure roller 704 moves down, it squeezes the hose 5 with the second conveyor belt 604.

[0083] Then, the drive motor 609 is started. After the drive motor 609 is started, the transmission belt 604, the second transmission belt drive wheel 607, and the second transmission belt tension wheel 603 rotate, and the hose 5 is conveyed upward. The pressure roller 704 rotates at the same time. The pressure roller 704 and the second transmission belt 604 squeeze the hose 5, which can improve the lifting force of the hose 5 and prevent the hose 5 from slipping on the second transmission belt 604.

[0084] During the upward movement of hose 5, hose 5 passes around the packing guide wheel 608 and then descends vertically.

[0085] A packaging box is placed on top of the movable pallet 803, with the opening of the box facing upwards and one side of the inside of the box aligned with the end of the hose 5. When the end of the hose 5 enters the packaging box and contacts the bottom, the platform motor 806 is started. The platform motor 806 rotates forward and backward, which in turn causes the ball screw 804 to rotate forward and backward. During the forward and backward rotation of the ball screw 804, the movable pallet 803 and the packaging box move back and forth horizontally, allowing the hose 5 to be stacked in an S-shape inside the packaging box. After the end of the hose 5 falls from the second conveyor belt 604 into the packaging box, the packaging box is sealed and removed from the movable pallet 803.

[0086] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
