Description

Technical Field

[0001] This utility model relates to the field of trenchless light-curing repair hose manufacturing technology, specifically to a light-curing hose forming machine. Background Technology

[0002] Currently, there is no known equipment for manufacturing trenchless UV-curing repair hoses for pipelines in China. Most existing methods involve manual layer-by-layer folding, where multiple people coordinate to manually fold layers of fabric laid flat on a work surface or floor into hoses of the appropriate size. This manual folding method results in uneven dimensions, internal wrinkles that affect the final repair quality, and requires multiple people, leading to low efficiency. Therefore, the development of a UV-curing hose forming machine has become a new challenge for technicians in my country's trenchless pipeline repair hose manufacturing equipment industry. Utility Model Content

[0003] The main purpose of this invention is to provide a photocurable tube forming machine that can automatically fold multi-layer flat fabric.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: A photocurable tube forming machine, installed on a base, includes a conveying component for pushing multi-layer flat fabric and a stacking component for folding the multi-layer flat fabric in layers. The stacking component is located above the conveying component and is fixedly connected to the conveying component.

[0005] The fabric folding assembly includes multiple fabric folding units, the number of which is equal to the number of layers of the flat fabric. The multiple fabric folding units are arranged sequentially in the conveying direction of the conveying assembly, and each of the multiple fabric folding units corresponds one-to-one with the multiple layers of flat fabric in the vertical direction. During the process of the conveying assembly conveying the multiple layers of flat fabric, the multiple fabric folding units can fold the multiple layers of flat fabric sequentially from top to bottom. The fabric stacking unit includes two fabric stacking supports. The lower end of the fabric stacking supports is fixedly connected to the conveying component. The two fabric stacking supports are symmetrically arranged front and back. Each fabric stacking support is equipped 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.

[0006] It also includes a core mold assembly, which is located above the conveying assembly and is fixedly connected to the conveying assembly. The core mold assembly is located in front of the fabric stacking assembly.

[0007] Specifically, the conveying assembly includes a frame mounted on a foundation. The lower end of the fabric stacking bracket is fixedly connected to the upper end of the frame. A conveyor belt tensioning wheel is mounted on the front end of the frame, and a conveyor belt drive wheel is mounted on the rear end of the frame. The conveyor belt is mounted on the conveyor belt tensioning wheel and the conveyor belt drive wheel. A lower conveyor belt idler roller is mounted on the belly of the frame to prevent the straight section below the conveyor belt from sagging. A conveyor belt support roller is mounted on the upper part of the frame to support the straight section above the conveyor belt. A conveyor belt support plate is mounted between the conveyor belt support rollers and is fixedly connected to the frame. The conveyor belt support plate supports the straight section above the conveyor belt. A first motor is mounted on the frame below the conveyor belt drive wheel and is drively connected to the conveyor belt drive wheel.

[0008] Specifically, the guiding assembly includes a fixed frame fixed to the fabric stacking bracket. Multiple guide rods are slidably arranged on the fixed frame in the left-right direction. The guide rods are fixedly connected to a sliding frame. A lead screw is rotatably connected to the fixed frame, passing through the sliding frame and threadedly connected to it. A second motor is fixed to the fixed frame, driving the lead screw to rotate. A fabric stacking template is fixed to the front end of the sliding frame. The two fabric stacking templates on the same fabric stacking unit have equal heights. In two adjacent fabric stacking units, the height of the fabric stacking template of the front fabric stacking unit is greater than the height of the fabric stacking template of the rear fabric stacking unit.

[0009] Specifically, the front end of the fabric template, away from the middle of the conveyor belt, is curved upwards to form an arc-shaped part. The rear end of the fabric template, away from the middle of the conveyor belt, is bent upwards to form an upper straight part. The fabric template portion below the arc-shaped part and the upper straight part forms a lower straight part. The upper straight part and the lower straight part are parallel. The upper straight part and the arc-shaped part are connected to the lower straight part in an arc transition. The arc-shaped part is connected to the upper straight part in an arc transition.

[0010] Specifically, the core mold assembly includes a fixed bracket, the lower end of which is fixedly connected to the upper end of the frame. A flat plate is fixed inside the lower end of the fixed bracket. The flat plate is horizontally positioned and corresponds to the multi-layer flat fabric placed on the conveyor belt.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By arranging multiple fabric stacking units (each unit corresponding to one layer of fabric) sequentially in the conveying direction, continuous and sequential folding of multiple layers of flat fabric (from top to bottom) is achieved. This avoids the inefficiency of traditional manual or single-layer processing, significantly improving production efficiency. It can also handle multi-layered structures simultaneously, facilitating subsequent sewing into flexible hoses. The conveying component propels the fabric, and the fabric stacking component automatically completes the folding without interrupting the process, reducing manual intervention.

[0012] 2. The guide assembly in the fabric folding unit allows the fabric folding template to be adjusted in the left and right directions, easily accommodating flat-laid fabrics of different widths. This enhances the equipment's versatility and suits diverse production needs without requiring replacement of major components. A second motor drives a lead screw, allowing the sliding frame and fabric folding template to move, ensuring precise guidance and folding of fabrics of different sizes.

[0013] 3. The design incorporates conveyor belt under-rollers, conveyor belt support rollers, and conveyor belt pallets to provide comprehensive support, preventing conveyor belt sagging or fabric misalignment. This ensures the stability of the equipment during long-term operation, reducing malfunctions and maintenance needs. The fabric stacking bracket is fixedly connected to the frame, enhancing overall rigidity.

[0014] 4. The fabric folding template guides the fabric bending and folding through a smooth, curved transition, avoiding tearing or wrinkling. The staggered guide components optimize the folding path, ensuring each layer of fabric is precisely folded, improving forming quality. The curved section causes the fabric to bend upwards, while the straight upper section completes the bending. The core mold component assists in positioning, ensuring parallel folds and accurate layering.

[0015] 5. The core mold assembly is located in front of the fabric stacking assembly. It corresponds to the multi-layer fabric through a flat plate and acts as an internal support during the folding process. During the subsequent folding of the flat fabric, the fabric that is folded first becomes the core mold of the fabric that is folded later. This simplifies the hose forming process, realizes the self-supporting layering of the fabric, facilitates subsequent light curing and sewing, reduces the need for additional tools, and the fabric stacking units sequentially make the flat fabric form a semi-enclosed structure, which is finally sewn into a hose, thus optimizing the overall process flow.

[0023] 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.

[0024] Reference Figures 1-6 As shown, a light-curing hose forming machine is installed on a base and includes a conveying component 1 for pushing 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.

[0025] The conveying assembly 1 includes a frame 106 mounted on a base. A conveyor belt tensioner 101 is mounted at the front end of the frame 106, and a conveyor belt drive wheel 107 is mounted at the rear end of the frame 106. A conveyor belt 102 is mounted on the conveyor belt tensioner 101 and the conveyor belt drive wheel 107. A lower conveyor belt idler roller 103 is mounted on the belly of the frame 106 to prevent the straight section below the conveyor belt 102 from sagging. A conveyor belt support roller 104 is mounted on the upper part of the frame 106 to support the straight section above the conveyor belt 102. A conveyor belt support plate 105 is mounted between the conveyor belt support rollers 104 and is fixedly connected to the frame 106. The conveyor belt support plate 105 supports the straight section above the conveyor belt 102. A first motor 108 is mounted on the frame 106 below the conveyor belt drive wheel 107 and is drively connected to the conveyor belt drive wheel 107.

[0026] The fabric folding assembly 3 includes multiple fabric folding units, the number of which is equal to the number of layers of the flat fabric 2. The multiple fabric folding units are arranged sequentially in the conveying direction of the conveying assembly 1, and each of the multiple fabric folding units corresponds one-to-one with the multiple layers of flat fabric 2 in the vertical direction. During the process of conveying the multiple layers of flat fabric 2 by the conveying assembly 1, the multiple fabric folding units can fold the multiple layers of flat fabric 2 sequentially from top to bottom.

[0027] The fabric stacking unit includes two fabric stacking supports 301, the lower ends of which are fixedly connected to the conveying assembly 1. Specifically, the lower ends of the fabric stacking supports 301 are fixedly connected to the upper ends of the frame 106.

[0028] Two fabric stacking brackets 301 are symmetrically arranged front and back. Each fabric stacking bracket 301 is equipped 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.

[0029] The guiding assembly 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.

[0030] The two fabric stacking templates 307 on the same fabric stacking unit have the same height.

[0031] 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.

[0032] The front end of the fabric folding template 307, away from the middle position of the conveyor belt 102, is curved upward to form an arc-shaped part 3073. The rear end of the fabric folding template 307, away from the middle position of the conveyor belt 102, is bent upward to form an upper straight part 3072. The portion 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.

[0033] It also includes a core mold assembly, which is located above the conveying assembly 1 and is fixedly connected to the conveying assembly 1. The core mold assembly is located in front of the fabric stacking assembly 3.

[0034] 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 conveyor belt 102.

[0035] When this molding machine is working, the multi-layer flat fabric 2 is placed above the front end of the conveyor belt 102, so that the multi-layer flat fabric 2 corresponds to the flat plate 401.

[0036] 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.

[0037] During the process of conveyor belt 102 conveying multi-layer flat fabric 2 from front to back, when the rear end of multi-layer flat fabric 2 moves to below the front end of 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, plate 401 is located inside the first layer of fabric.

[0038] As the conveyor belt 102 moves, the right-side fabric template 307 in the second fabric stacking unit guides the right side of the second layer of fabric. Then, the left-side fabric template 307 in the second fabric stacking unit guides the left side 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.

[0039] Multi-layered flat fabric can be folded sequentially through multiple overlapping units. After folding, the multi-layered flat fabric is sewn together to form a flexible tube 5.

[0040] When the two fabric folding templates 307 of the second fabric fold the left and right sides of the second layer of fabric, the first layer of fabric after being folded on the left and right sides becomes the core mold of the second layer of fabric.

[0041] In this embodiment, 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 machine can fold flat fabrics 2 of different widths.

[0042] like Figure 6As 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.

[0043] 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.
