Description

[0002] At present, drainage pipe networks are an indispensable and important infrastructure in modern cities. However, due to years of disrepair, the aging of materials and the influence of some external factors have led to pipe damage, causing sewage leakage. In response to this, the in-situ curing method (CIPP) is now commonly used to perform trenchless repairs on underground drainage pipes. In this repair method, the lining hose needs to be extended into the damaged pipe and the lining hose is cured on the inside of the damaged pipe by steam heating, thereby achieving pipe repair.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0041] Please refer to Figures 1 to 5 The embodiment of the present invention provides a hose production line (not shown) for producing lined hoses. It can realize automatic reversing of the flat hose 300, has a high degree of mechanization, saves time and labor, saves time and labor costs, has high reversing efficiency, and has good reversing effect.

[0042] It should be noted that the hose production line includes a hose production device (not shown) and a reversing device 100. The hose production device is used to produce liner hoses, and the liner hoses are flattened and sent to the reversing device 100 through a conveying roller. The flattened liner hoses are flat hoses 300. The reversing device 100 is used to reverse the laminating direction of the flat hose 300 to ensure the strength and toughness of the liner hoses and extend the service life of the liner hoses.

[0043] In this embodiment, the lining hose is a braided reinforcement layer, which is made of polyester staple fiber material, but is not limited to this. The lining hose can be an inner lining layer or a protective layer. Both the inner lining layer and the protective layer are made of polyethylene, polyvinyl chloride or polypropylene. The material of the lining hose is not specifically limited.

[0044] The reversing device 100 includes a frame 110, a feeding roller 120, a steering roller 130, a reversing assembly 140, an output roller 150, a first supporting roller 160, a second supporting roller 170, a first limiting roller 180, a second limiting roller 190, a third limiting roller 200, a fourth limiting roller 210, a driving member 220 and a tensioning roller 230. The feeding roller 120, the steering roller 130, the reversing assembly 140 and the output roller 150 are all mounted on the frame 110, and the feeding roller 120 and the output roller 150 can rotate relative to the frame 110. The feed roller 120 is arranged in parallel with the output roller 150, and the feed roller 120 and the steering roller 130 are arranged at a first preset angle. The reversing component 140 is arranged between the steering roller 130 and the output roller 150. The feed roller 120 is used to send the flat hose 300 to the steering roller 130. The steering roller 130 is used to turn the flat hose 300 and rub the two sides of the flat hose 300 that are bonded to each other apart so that the flat hose 300 is sleeved outside the reversing component 140. The reversing component 140 is used to convert the initial bonding surface 310 of the flat hose 300 into a reversing bonding surface 320, and send the flat hose 300 after reversing to the output roller 150. The output roller 150 is used to send the flat hose 300 after reversing to facilitate the next process. The initial laminating surface 310 is perpendicular to the reversing laminating surface 320, that is, the reversing assembly 140 can reverse the laminating direction of the flat hose 300 by 90 degrees, and the flat hose 300 can be fully extended during the reversing process, thereby improving its strength and toughness. In this way, the flat hose 300 can be automatically reversing, with a high degree of mechanization, saving time and labor, saving time and labor costs, and having high reversing efficiency and good reversing effect.

[0045] It should be noted that the first supporting roller 160, the second supporting roller 170, the first limiting roller 180, the second limiting roller 190, the third limiting roller 200 and the fourth limiting roller 210 can be rotatably installed on the frame 110, wherein the first supporting roller 160 and the second supporting roller 170 are used to support the reversing component 140, the first limiting roller 180 and the second limiting roller 190 are used to limit one end of the reversing component 140, the third limiting roller 200 and the fourth limiting roller 210 are used to limit the other end of the reversing component 140, and the first supporting roller 160, the second supporting roller 170, the first limiting roller 180, the second limiting roller 190, the third limiting roller 200 and the fourth limiting roller 210 work together to prevent the reversing component 140 from falling off the frame 110.

[0046] Furthermore, the driving member 220 is installed on the frame 110 and connected to the tensioning roller 230. The tensioning roller 230 is arranged in close contact with the flat hose 300. The driving member 220 can drive the tensioning roller 230 to move in its radial direction during the feeding process of the flat hose 300 to adjust the tensioning force of the flat hose 300 and ensure the feeding stability of the flat hose 300.

[0047] Please refer to Figure 6 and Figure 7 The reversing assembly 140 includes a first guide frame 141, a connecting frame 142, a second guide frame 143, a first transition wheel 144, and a second transition wheel 145. The first guide frame 141, the connecting frame 142, and the second guide frame 143 are connected in sequence, and the first guide frame 141, the connecting frame 142, and the second guide frame 143 are used to allow the flat hose 300 to pass through in sequence, that is, the flat hose 300 passes through the first guide frame 141, the connecting frame 142, and the second guide frame 143 in sequence during the feeding process. The first guide frame 141 is used to further expand the flat hose 300 that is rubbed open by the steering roller 130, the connecting frame 142 is used to fix the relative positions of the first guide frame 141 and the second guide frame 143, and the second guide frame 143 is used to open the flat hose 300 along the vertical direction thereof to reverse the laminating direction of the flat hose 300. Specifically, the first guide frame 141 and the second guide frame 143 are arranged at a second preset angle, that is, the direction in which the first guide frame 141 expands the flat hose 300 and the direction in which the second guide frame 143 opens the flat hose 300 are arranged at a second preset angle, so as to realize the reversing function. The axis of the output roller 150 is parallel to the plane where the second guide frame 143 is located, and the flat hose 300 after reversing through the second guide frame 143 can be attached to the outside of the output roller 150, so that the output roller 150 can send it outward.

[0048] In this embodiment, the feed roller 120 is arranged in parallel with the output roller 150, and the first preset angle is smaller than the second preset angle. When the flat hose 300 moves from the feed roller 120 to the steering roller 130, the flat hose 300 realizes the first preset angle of steering, and the flat hose 300 is arranged along the initial laminating surface 310 at this time, and the angle of rotation of the flat hose 300 is the first preset angle; when the flat hose 300 moves from the steering roller 130 to the first guide frame 141, the flat hose 300 realizes the second preset angle of steering, and the angle of rotation of the flat hose 300 is equal to the second preset angle minus the first preset angle; when the flat hose 300 moves from the first guide frame 141 to the second guide frame 143, the flat hose 300 no longer turns, but changes the laminating direction under the action of the second guide frame 143, and then the flat hose 300 is arranged along the reversing laminating surface 320 and sent out along the output roller 150.

[0049] It is worth noting that the first preset angle ranges from 40 degrees to 50 degrees, and the second preset angle ranges from 80 degrees to 90 degrees. Reasonable first preset angle and second preset angle can make the flat hose 300 gradually turn twice during the feeding process, so that the flat hose 300 has an adaptation process to prevent the flat hose 300 from being damaged due to a sudden change in the turning angle. For ease of understanding, the first preset angle is represented as A and the second preset angle is represented as B. In this embodiment, the first preset angle is 45 degrees and the second preset angle is 85 degrees, but it is not limited to this. In other embodiments, the first preset angle can be 40 degrees or 50 degrees, and the second preset angle can be 80 degrees or 90 degrees. The sizes of the first preset angle and the second preset angle are not specifically limited.

[0050] It should be noted that the second preset angle between the first guide frame 141 and the second guide frame 143 is in the range of 80 to 90 degrees, rather than a fixed 90 degrees, because the flat hose 300 may slip during the turning process driven by the turning roller 130, causing the position of the initial fitting surface 310 of the flat hose 300 to change, and in order to ensure that the initial fitting surface 310 is perpendicular to the reversing fitting surface 320, the second preset angle needs to be appropriately corrected to compensate for the slippage of the flat hose 300. Therefore, the size of the second preset angle needs to be determined according to actual conditions to ensure that the reversing assembly 140 can perform a 90-degree reversal of the fitting direction of the flat hose 300.

[0051] In this embodiment, the steering roller 130 is arranged at the top of the frame 110, and the output roller 150 is arranged at the bottom of the frame 110, that is, the steering roller 130 is arranged above the output roller 150, and the first guide frame 141, the connecting frame 142 and the second guide frame 143 are arranged in sequence from top to bottom. The flat hose 300 passes through the first guide frame 141, the connecting frame 142 and the second guide frame 143 in sequence from top to bottom during the feeding process.

[0052] Please refer to Figure 8 The first guide frame 141 includes a fixing rod 1411, a first support rod 1412, a second support rod 1413 and a connecting rod 1414. The fixing rod 1411 is connected to the connecting frame 142, one end of the fixing rod 1411 is connected to the first support rod 1412, and the other end is connected to the second support rod 1413, and the first support rod 1412 is connected to the second support rod 1413 through the connecting rod 1414. Specifically, the first guide frame 141 is similar to the shape of a clothes hanger, and the first support rod 1412 and the second support rod 1413 are extended in a relatively inclined direction to expand the flat hose 300 from the inside thereof, so that the two sides of the flat hose 300 are no longer attached.

[0053] Specifically, the first support rod 1412 includes a linear segment 1415 and an arc segment 1416. The fixing rod 1411 is connected to the linear segment 1415, one end of the arc segment 1416 is connected to the linear segment 1415, and the other end is connected to the connecting rod 1414. The linear segment 1415 and the connecting rod 1414 work together to provide support force to the arc segment 1416 and fix the relative position of the arc segment 1416. The arc segment 1416 is used to directly contact the inner wall of the flat hose 300. Since the arc segment 1416 has no spikes and protrusions, it can avoid scratching the inner wall of the flat hose 300 and prevent the flat hose 300 from being damaged during the reversing process.

[0054] In this embodiment, the specific structure of the second support rod 1413 is the same as the specific structure of the first support rod 1412, and will not be repeated here.

[0055] In this embodiment, the specific structure of the second guide frame 143 is the same as the specific structure of the first guide frame 141, which will not be repeated here. The second guide frame 143 is used to expand the flat hose 300 from the inside along the mid-vertical direction of the flat hose 300 to realize the reversing function of the flat hose 300.

[0056] It is worth noting that the first transition wheel 144 and the second transition wheel 145 are both rotatably mounted on the connecting frame 142 and are disposed between the first guide frame 141 and the second guide frame 143. The first transition wheel 144 and the second transition wheel 145 are disposed on both sides of the second guide frame 143, and the axes of the first transition wheel 144 and the second transition wheel 145 are parallel to the axis of the output roller 150. The first transition wheel 144 and the second transition wheel 145 are both used to guide the inner wall of the flat hose 300. Specifically, the first transition wheel 144 and the second transition wheel 145 are both disposed in close contact with the inner wall of the flat hose 300, and the first transition wheel 144 and the second transition wheel 145 can rotate as the flat hose 300 is fed, so that the flat hose 300 smoothly transitions from the first guide frame 141 to the second guide frame 143, preventing the flat hose 300 from getting stuck during the reversing process, and improving the stability of the reversing of the flat hose 300.

[0057] In this embodiment, the number of the first transition wheels 144 and the number of the second transition wheels 145 are both two, the two first transition wheels 144 are coaxially spaced, the two second transition wheels 145 are coaxially spaced, and the two first transition wheels 144 and the two second transition wheels 145 work together to guide the transition of the inner wall of the flat hose 300, further improving the stability of the reversal of the flat hose 300. However, this is not limited to this, in other embodiments, the number of the first transition wheels 144 and the second transition wheels 145 can be three or four, and the number of the first transition wheels 144 and the second transition wheels 145 is not specifically limited.

[0058] Please continue to refer to Figure 1 and Figure 2 It should be noted that the first supporting roller 160 and the second supporting roller 170 are combined to form a pair of rollers. The first supporting roller 160 and the second supporting roller 170 are both installed on the frame 110 and are parallel to the axes of the first transition wheel 144 and the second transition wheel 145. The first supporting roller 160 and the second supporting roller 170 can rotate relative to the frame 110. The first supporting roller 160 and the second supporting roller 170 are used to carry the first transition wheel 144 and the second transition wheel 145. Specifically, the first transition wheel 144 and the second transition wheel 145 are both arranged between the first supporting roller 160 and the second supporting roller 170 and are located above the first supporting roller 160 and the second supporting roller 170. The first supporting roller 160 is used to carry the first transition wheel 144, and the second supporting roller 170 is used to carry the second transition wheel 145. The first supporting roller 160 and the second supporting roller 170 work together to carry the weight of the entire reversing assembly 140 through the first transition wheel 144 and the second transition wheel 145.

[0059] Furthermore, one side of the flat hose 300 passes between the first supporting roller 160 and the first transition wheel 144, and the other side passes between the second supporting roller 170 and the second transition wheel 145. The flat hose 300 can synchronously drive the first supporting roller 160, the first transition wheel 144, the second supporting roller 170 and the second transition wheel 145 to rotate during the feeding process. The first supporting roller 160 and the first transition wheel 144 rotate relative to each other to ensure that one side of the flat hose 300 is smoothly conveyed forward; the second supporting roller 170 and the second transition wheel 145 rotate relative to each other to ensure that the other side of the flat hose 300 is smoothly conveyed forward.

[0060] It is worth noting that the first limiting roller 180 and the second limiting roller 190 are combined to form a pair of rollers, and the first limiting roller 180 and the second limiting roller 190 are both installed on the frame 110 and are parallel to the plane where the first guide frame 141 is located. The first limiting roller 180 and the second limiting roller 190 can rotate relative to the frame 110.
