[0054] Refer to Figures 1 to 3 and Figure 7, a welded pipe device according to an embodiment of the first aspect of the present invention, the welded pipe device includes a frame 10, a feeding mechanism 20, a welding mechanism 30 and a limiting mechanism 40. A traction mechanism 50 is provided on the frame 10, and the traction mechanism 50 is configured to be able to traction the resin hose 1; the feeding mechanism 20 is provided on the frame 10, the feeding mechanism 20 is located on the other side of the frame 10 relative to the traction mechanism 50, the feeding mechanism 20 is configured to be able to convey the resin hose 1, there are two feeding mechanisms 20, and the two feeding mechanisms 20 are respectively located on opposite sides of the frame 10; the welding mechanism 30 is provided on the frame 10, the welding mechanism 30 is located between the two feeding mechanisms 20, the welding end of the welding mechanism 30 is located at the intersection of the two resin hoses 1, and the welding mechanism 30 is configured to be able to heat the welding part of the two resin hoses 1; the limiting mechanism 40 is provided on the frame 10, the limiting mechanism 40 is located between the welding mechanism 30 and the traction mechanism 50, the limiting mechanism 40 includes a first limiting component 41, the first limiting component 41 includes a first mounting seat 411 and a rotatable first limiting wheel 412, the first limiting wheels 412 are arranged along the conveying direction of the resin hose 1 on the first mounting seat 411, a first limiting groove 4121 is provided on the outer peripheral side of the first limiting wheel 412, the two first limiting grooves 4121 are arranged oppositely, the first limiting wheels 412 are respectively arranged on both sides of the resin hose 1, the resin hose 1 is arranged between the first limiting grooves 4121, and the resin hose 1 is configured to be able to pass between the first limiting wheels 412 and be bonded to each other.

[0055] The welded pipe device of the present invention first arranges two feeding mechanisms 20 on opposite sides of the frame 10, which can convey two resin hoses 1 simultaneously, greatly improving the welding efficiency and making the welding process of the resin hose 1 more automated and continuous. The welding mechanism 30 is located between the two feeding mechanisms 20, and its welding end is accurately aligned with the intersection of the two resin hoses 1, ensuring the accuracy of the welding position and thus improving the welding quality. The setting of the limiting mechanism 40, especially the first limiting wheel 412 and the first limiting groove 4121 on the first limiting component 41, can effectively limit and guide the resin hose 1, ensuring that the resin hose 1 remains stable during the welding process, avoiding deviation or misalignment, and further improving the accuracy and reliability of welding. In addition, the rotatable design of the first limiting wheel 412 enables the resin hose 1 to pass more smoothly, reduces the frictional resistance, and protects the surface quality of the resin hose 1. Overall, the welded pipe device of the present invention has a reasonable structure and is easy to operate, and can efficiently and accurately complete the welding work of the resin hose 1, having wide industrial application value.

[0056] Specifically, this embodiment provides a welding pipe device, which mainly includes a frame 10, a traction mechanism 50, a feeding mechanism 20, a welding mechanism 30 and a limiting mechanism 40. The frame 10 serves as the support structure of the entire device, on which a traction mechanism 50 is provided. The traction mechanism 50 is configured to be able to traction the resin hose 1 to ensure that the resin hose 1 can move along a predetermined path and speed during the welding process. On the other side of the frame 10 relative to the traction mechanism 50, two feeding mechanisms 20 are provided. These two feeding mechanisms 20 are respectively located on opposite sides of the frame 10 and can simultaneously convey two resin hoses 1. The design of the feeding mechanism 20 enables the resin hose 1 to be stably and continuously conveyed to the welding position, improving the welding efficiency. The welding mechanism 30 is provided on the frame 10 and is located between the two feeding mechanisms 20. The welding end of the welding mechanism 30 is precisely aligned with the intersection of the two resin hoses 1 and is configured to be able to heat the welding joints of the two resin hoses 1 to achieve the fusion welding of the resin hoses 1. The welding mechanism 30 can adopt resistance heating, high-frequency induction heating or other suitable heating methods to ensure that the temperature at the welding joint reaches the fusion requirements. Between the welding mechanism 30 and the traction mechanism 50, a limiting mechanism 40 is provided. The limiting mechanism 40 includes a first limiting component 41, which is composed of a first mounting seat 411 and a rotatable first limiting wheel 412. The first limiting wheels 412 are arranged along the conveying direction of the resin hose 1 on the first mounting seat 411, and a first limiting groove 4121 is provided on the outer peripheral side thereof. The first limiting grooves 4121 on both sides are arranged oppositely, and the first limiting wheels 412 are respectively arranged on both sides of the resin hose 1. The resin hose 1 is arranged between the first limiting grooves 4121. Through the limiting and guiding effects of the first limiting wheels 412, the two resin hoses 1 can pass between the first limiting wheels 412 and be bonded to each other.

[0057] During the actual use process, the operator only needs to place the resin hose 1 on the feeding mechanism 20. After starting the device, the feeding mechanism 20 conveys the resin hose 1 to the welding position. The welding mechanism 30 heats and fuses the welding joints of the resin hose 1, and at the same time, the limiting mechanism 40 ensures the stability and accuracy of the resin hose 1. The traction mechanism 50 then tractions the resin hose 1 to move along a predetermined path and speed to complete the entire welding process. The welding pipe device of the present invention has a simple structure, convenient operation, high welding efficiency and reliable welding quality, and is suitable for the welding work of various resin hoses 1.

[0058] Therefore, it can be understood that the welded pipe device according to the embodiment of the present invention has at least the following beneficial effects: The resin hose 1 can be conveyed in the feeding mechanism 20 and the limiting mechanism 40 by the traction of the traction mechanism 50 provided on the frame 10. During the conveying process, the welding end of the welding mechanism 30 heats the intersection between the two resin hoses 1, causing the welding part on the surface of the resin hose 1 to melt, facilitating the mutual bonding of the resin hoses 1 in the limiting mechanism 40, and thus realizing the welding of the resin hoses 1. It should be noted that in order to ensure the bonding stability and the integrity of the resin hose 1, the width of the welding part on the resin hose 1 should be no more than 3 mm. In the limiting mechanism 40, the first limiting wheel 412 restricts and presses the two resin hoses 1 in the first limiting groove 4121, facilitating the mutual fusion and bonding of the two resin hoses 1.

[0059] Refer to Figures 7 to 9 , it should be particularly noted that the welded pipe equipment provided by the embodiment of the present invention can not only weld double pipes, but also weld triple pipes, quadruple pipes, and even more resin hoses. Therefore, it can be imagined that the output end of the traction mechanism 50 can output the welded double pipes (welding of two resin hoses 1), triple pipes (welding of a single resin hose and a double hose), quadruple pipes (welding of two double pipes), etc.; and on the feeding mechanisms 20 respectively arranged on both sides of the welding mechanism 30, single pipes, welded double pipes, and even welded triple pipes can be respectively conveyed to meet the welding requirements of multi-pipe. Therefore, the resin hose welding machine in this embodiment is applicable to the welding of multi-pipes, with stronger applicability, and at the same time, the limiting mechanism 40 is beneficial to the stability of the multi-pipes during the welding process.

[0060] Refer to Figures 2 to 4 and Figure 7, in some embodiments of the present invention, the limiting mechanism 40 includes a second limiting component 42. The second limiting component 42 is located in the vertical direction of the first limiting component 41. The first limiting component 41 includes a first abutting member 421. The first abutting member 421 is disposed on the frame 10. The first abutting member 421 is located below the first mounting seat 411. The first abutting member 421 is configured to be able to abut against the outer peripheral surface of the resin hose 1. The first abutting member 421 includes a first driving member 4211 and a first abutting piece 4212. The first driving member 4211 is disposed on the frame 10, and the output end of the first driving member 4211 extends in the vertical direction; the first abutting piece 4212 is configured to be able to move up and down between the first limiting grooves 4121. The resin hose 1 is located on the upper end surface of the first abutting piece 4212. The upper end surface of the first abutting piece 4212 is configured to be able to abut against the outer peripheral surface of the resin hose 1. The first abutting piece 4212 is disposed on the output end of the first driving member 4211. The first driving member 4211 is configured to be able to drive the first abutting piece 4212 to move up and down in the vertical direction.

[0061] In the welded pipe device of this embodiment, a second limiting component 42 is further provided as part of the limiting mechanism 40. The second limiting component 42 is located in the vertical direction of the first limiting component 41 and cooperates with the first limiting component 41 to more comprehensively limit and guide the position of the resin hose 1. In the first limiting component 41, a first abutting member 421 is particularly provided. This member is installed on the frame 10 and is located below the first mounting seat 411. Its main function is to abut against the outer peripheral surface of the resin hose 1 to ensure that the resin hose 1 maintains a stable vertical position during the welding process. The first abutting member 421 specifically includes a first driving member 4211 and a first abutting piece 4212. The first driving member 4211 is fixed on the frame 10, and its output end extends in the vertical direction to provide power support for the first abutting piece 4212. The first abutting piece 4212 is configured to be able to move up and down between the first limiting grooves 4121, and its upper end surface is in contact with and abuts against the outer peripheral surface of the resin hose 1.

[0062] During the actual operation process, when the resin hose 1 passes through the first limiting groove 4121 between the first limiting wheels 412, the first driving member 4211 drives the first abutting member 4212 to move upward in the vertical direction until the upper end surface thereof abuts against the outer peripheral side surface of the resin hose 1. In this way, the position of the resin hose 1 in the vertical direction is limited, effectively preventing the resin hose 1 from shifting or shaking in the vertical direction due to external forces during the welding process; in particular, for resin hoses 1 with a quantity of more than three; during fusion welding (fusion welding of a double tube and a single tube, fusion welding of a double tube and a double tube, or fusion welding of a multi-tube and a multi-tube), the first abutting member 4212 can abut against the outer peripheral side surface of the resin hose 1, that is, the position of the lowest point on the outer peripheral side of the resin hose 1, so as to ensure that it will not tilt or overturn during the fusion welding and conveying processes, and further ensure the stability of the fusion welding of the resin hose 1.

[0063] Through the arrangement of the first abutting member 421, the pipe welding device of this embodiment not only improves the stability of the resin hose 1 during the welding process, but also further ensures the reliability of the welding quality. At the same time, since the first abutting member 421 is driven by the first driving member 4211 to achieve lifting and lowering, its abutting force and position can be flexibly adjusted according to actual needs, making the entire pipe welding device have higher adaptability and practicality.

[0064] Furthermore, referring to Figures 3 to 4 , in some embodiments of the present invention, the first abutting member 4212 has an avoidance groove 4212a, and the avoidance groove 4212a is configured to be able to avoid the first limiting wheel 412, and a part of the groove wall of the avoidance groove 4212a is located between two adjacent first limiting wheels 412.

[0065] Specifically, the first abutting member 4212 is provided with an avoidance groove 4212a, and this design solves the problem of the spatial layout between the first abutting member 4212 and the first limiting wheel 412. The avoidance groove 4212a is carefully configured to be able to avoid the first limiting wheel 412, ensuring that there will be no interference or collision with the first limiting wheel 412 during the lifting and lowering process of the first abutting member 4212. A part of the groove wall of the avoidance groove 4212a is cleverly located between two adjacent first limiting wheels 412, so that even when the first abutting member 4212 rises to the highest position, its groove wall will not exceed the outer contour of the first limiting wheel 412, thus ensuring the compactness and coordination of the entire limiting mechanism 40.

[0066] In practical applications, when the first driving member 4211 drives the first abutting member 4212 to rise to abut against the resin hose 1, the presence of the avoidance groove 4212a enables the first abutting member 4212 to smoothly pass through the gap between the first limiting wheels 412 and come into close contact with the outer peripheral surface of the resin hose 1. At the same time, since there is a certain gap between the groove wall of the avoidance groove 4212a and the first limiting wheels 412, even if the resin hose 1 shakes or deflects slightly during the welding process, it will not affect the stable abutting effect of the first abutting member 4212. In short, the design of the avoidance groove 4212a not only improves the space utilization rate between the first abutting member 4212 and the first limiting wheels 412, but also enhances the stability and reliability of the pipe welding device during the welding process, further improving the welding quality.

[0067] Furthermore, referring to Figures 2 to 4 and Figure 7 , in some embodiments of the present invention, the second limiting assembly 42 further includes a second abutting member 422. The second abutting member 422 is disposed on the frame 10. The second abutting member 422 is located above the first mounting seat 411. The second abutting member 422 is configured to be able to abut against the outer peripheral surface of the resin hose 1. The second abutting member 422 includes a second driving member 4221 and a second abutting member 4222. The second driving member 4221 is disposed on the frame 10, and the output end of the second driving member 4221 extends in the vertical direction; the second abutting member 4222 is configured to be able to be lifted and lowered between the first limiting grooves 4121. The resin hose 1 is located at the lower end surface of the second abutting member 4222, and the lower end surface of the second abutting member 4222 is configured to be able to abut against the outer peripheral surface of the resin hose 1. The second abutting member 4222 is disposed on the output end of the second driving member 4221, and the second driving member 4221 is configured to be able to drive the second abutting member 4222 to move up and down in the vertical direction.

[0068] In the pipe welding device of this embodiment, a second abutting member 422 in the second limiting assembly 42 is further added to achieve more comprehensive limiting of the resin hose 1 in the vertical direction. The second abutting member 422 is cleverly installed on the frame 10 and is located above the first mounting seat 411. This position design enables the second abutting member 422 to cooperate with the first abutting member 421 up and down to jointly abut against the outer peripheral surface of the resin hose 1, thereby enhancing the stability of the resin hose 1 during the welding process. The second abutting member 422 specifically includes a second driving member 4221 and a second abutting member 4222. The second driving member 4221 is fixed on the frame 10, and its output end extends in the vertical direction, providing precise power support for the second abutting member 4222. The second abutting member 4222 is configured to be able to be lifted and lowered between the first limiting grooves 4121, and its lower end surface contacts and abuts against the outer peripheral surface of the resin hose 1.

[0069] During the actual operation process, when the resin hose 1 passes through the first limiting groove 4121 between the first limiting wheels 412, the second driving member 4221 drives the second abutting member 4222 to move downward in the vertical direction until the lower end surface thereof abuts against the outer peripheral side surface of the resin hose 1. In this way, the position of the resin hose 1 in the vertical direction is firmly limited by the upper and lower first abutting members 4212 and the second abutting member 4222, effectively preventing the resin hose 1 from shifting, shaking or deforming in the vertical direction due to external forces during the welding process. Through the arrangement of the second abutting member 422, the pipe welding device of this embodiment not only further improves the stability of the resin hose 1 during the welding process, but also ensures the reliability and consistency of the welding quality. At the same time, since the second abutting member 422 is driven by the second driving member 4221 to realize lifting and lowering, its abutting force and position can be flexibly adjusted according to actual needs, making the entire pipe welding device have higher adaptability and practicability.

[0070] It should be noted that the second abutting member 4222 can be an abutting plate or a rotatable abutting rod arranged along the conveying direction of the resin hose 1. The rotatable abutting rods arranged along the conveying direction of the resin hose 1 are more conducive to the stable conveying of the resin hose 1 and facilitate the fusion welding of the resin hose 1.

[0071] Refer to Figures 2 to 4 And Figure 7 In some embodiments of the present invention, the first limiting assembly 41 further includes a third driving member 413. There are two third driving members 413, and the two third driving members 413 are respectively arranged on opposite sides of the frame 10. The first mounting seats 411 are respectively arranged at the output ends of the two third driving members 413, and the third driving member 413 is configured to be able to drive the first mounting seat 411 to move horizontally relative to or towards each other.

[0072] Specifically, there are two third driving members 413 arranged in the first limiting assembly 41, and these two third driving members 413 are respectively installed on opposite sides of the frame 10. Such a layout design enables the first mounting seats 411 to be respectively installed at the output ends of these two third driving members 413, thereby realizing the movability of the first mounting seats 411 in the horizontal direction. The third driving member 413 is configured to be able to drive the first mounting seat 411 to move horizontally relative to or towards each other. During actual operation, when it is necessary to adjust the distance between the two first limiting wheels 412 to adapt to resin hoses 1 with different diameters or different numbers of resin hoses 1, only need to start the third driving member 413, and it can drive the first mounting seat 411 to drive the first limiting wheels 412 to move in the horizontal direction. If the diameter of the resin hose 1 is larger, the two first mounting seats 411 can be moved relative to each other to increase the distance; conversely, if the diameter of the resin hose 1 is smaller, the two first mounting seats 411 can be moved towards each other to reduce the distance.

[0073] This design not only improves the versatility of the pipe welding device, enabling it to handle resin hoses 1 of different diameters, but also enhances the stability and accuracy of the device during welding. This is because by accurately adjusting the spacing of the first limiting wheels 412, it is possible to ensure that the resin hose 1 always maintains the correct position during welding, avoiding deviation or shaking caused by improper spacing, thereby further improving the welding quality.

[0074] Reference Figures 1 to 2 as well as Figure 5 In some embodiments of the present invention, further, the feeding mechanism 20 includes a tensioning assembly 21, a third limiting assembly 22 and a guiding assembly 23, the tensioning assembly 21 is arranged on the frame 10, the tensioning assembly 21 is located upstream of the conveying direction of the resin hose 1, the tensioning assembly 21 includes a tensioning roller 211, the axis of the tensioning roller 211 is horizontally placed on the frame 10, and the position of the tensioning roller 211 is floating; the third limiting assembly 22 is arranged on the frame 10, the resin hose 1 is configured to be able to pass through the third limiting assembly 22, and the third limiting assembly 22 is configured to be able to guide the resin hose 1 to be conveyed along the direction of the limiting mechanism 40; the guiding assembly 23 is arranged on the frame 10, the guiding assembly 23 is located between the third limiting assembly 22 and the limiting mechanism 40, and the guiding assembly 23 is configured to be able to guide the resin hose 1 to be conveyed along the direction of the limiting mechanism 40.

[0075] In the welded pipe device of this embodiment, further, the feeding mechanism 20 includes a tensioning assembly 21, which is installed on the frame 10 and is located upstream of the conveying direction of the resin hose 1. The core component of the tensioning assembly 21 is the tensioning roller 211, whose axis is horizontally placed on the frame 10, and the position of the tensioning roller 211 is designed to be floating. In this way, when the resin hose 1 passes through the tensioning roller 211, the tensioning roller 211 can automatically adjust its position according to the tension of the resin hose 1, maintain an appropriate tension force, and ensure that the resin hose 1 will not affect the welding quality due to slack or excessive tightness during the conveying process. Immediately downstream of the tensioning assembly 21 in the conveying direction is the third limiting assembly 22, which is also arranged on the frame 10. The resin hose 1 is configured to be able to pass through the third limiting assembly 22, so that the third limiting assembly 22 can effectively guide the resin hose 1 to be conveyed along the direction of the limiting mechanism 40. The design of the third limiting assembly 22 ensures the path stability and accuracy of the resin hose 1 during the conveying process, and avoids welding problems caused by the deviation or shaking of the resin hose 1. Between the third limiting assembly 22 and the limiting mechanism 40, a guiding assembly 23 is also arranged. The guiding assembly 23 is also installed on the frame 10, and its function is to further guide the resin hose 1 to be conveyed along the direction of the limiting mechanism 40. By arranging the guiding assembly 23, it can be ensured that the resin hose 1 is already on the correct conveying path before entering the limiting mechanism 40, so that the resin hoses 1 on both sides can intersect at the welding end of the welding mechanism 30, making full preparations for the subsequent welding process.

[0076] Referring to Figures 1 to 2 and Figure 5 , in some embodiments of the present invention, the third limiting assembly 22 includes a second mounting seat 221 and a rotatable second limiting wheel 222. The second mounting seat 221 is arranged on the frame 10, there are two second mounting seats 221, and the two second mounting seats 221 are arranged at intervals, and the two second mounting seats 221 are configured to be able to adjust the relative positions of the two second mounting seats 221; at least one second limiting wheel 222 is arranged on the second mounting seat 221, a second limiting groove 2221 is arranged on the outer peripheral side of the second limiting wheel 222, the two second limiting grooves 2221 on both sides are arranged at intervals, the second limiting wheels 222 are respectively arranged on both sides of the resin hose 1, the resin hose 1 is arranged between the second limiting grooves 2221, and the resin hose 1 is configured to be able to pass between the second limiting wheels 222.

[0077] Specifically, the third limiting component 22 includes two second mounting seats 221 which are firmly arranged on the frame 10 and are spaced apart from each other. Such a design enables the relative positions between the two second mounting seats 221 to be adjusted, so as to adapt to resin hoses 1 of different diameters or shapes. By adjusting the distance between the two second mounting seats 221, it can be ensured that the resin hose 1 can be properly limited and guided when passing through the third limiting component 22. On each second mounting seat 221, at least one rotatable second limiting wheel 222 is arranged. Second limiting grooves 2221 are provided on the outer peripheral sides of these second limiting wheels 222, and the second limiting grooves 2221 on both sides are spaced apart to form a passage for the resin hose 1 to pass through. The second limiting wheels 222 are respectively installed on both sides of the resin hose 1, so that the resin hose 1 is arranged between the second limiting grooves 2221. When the resin hose 1 passes through the third limiting component 22, it will advance stably along the passage formed by the second limiting grooves 2221 on both sides. The rotatable design of the second limiting wheels 222 reduces the friction when the resin hose 1 passes through, enabling the resin hose 1 to pass through more smoothly. At the same time, due to the spaced arrangement of the second limiting grooves 2221, the resin hose 1 can maintain the stability of its shape and position when passing through, avoiding welding problems caused by offset or shaking.

[0078] Referring to Figures 1 to 2 and Figure 5 , Figure 7 , in some embodiments of the present invention, the guiding component 23 includes a guiding sleeve 231 which is arranged on the frame 10. The resin hose 1 is conveyed in the guiding sleeve 231, and the guiding sleeve 231 is configured to be able to guide the resin hose 1 to be conveyed into the limiting mechanism 40. The shape of the through hole of the guiding sleeve 231 is in imitation of the cross-sectional shape of the resin hose 1.

[0079] Specifically, the core component of the guiding component 23 is the guiding sleeve 231 which is firmly arranged on the frame 10 and becomes a key link in the conveying path of the resin hose 1. During the conveying process of the resin hose 1, it will pass through this guiding sleeve 231, and the guiding sleeve 231 guides the resin hose 1 to be conveyed in the correct direction. It is particularly worth mentioning that the shape of the through hole of the guiding sleeve 231 is designed to be in imitation of the cross-sectional shape of the resin hose 1. This means that no matter whether the cross-section of the resin hose 1 is circular, elliptical, the shape of a multi-tube or other shapes, the through hole of the guiding sleeve 231 can closely match it, providing all-round support and guidance for the resin hose 1. Of course, in addition to the shape of the guiding sleeve 231 matching the shape of the resin hose 1, it can also be adjusted according to the size of the resin hose 1 and can be replaced according to the size of the resin hose 1. This imitation design not only ensures the stability of the resin hose 1 during the conveying process, but also effectively prevents the resin hose 1 from deforming or offsetting due to uneven stress.

[0080] When the resin hose 1 passes through the guiding sleeve 231, due to the perfect match between the shape of the through hole and the cross-sectional shape of the resin hose 1, the resin hose 1 can maintain its original shape and position and be smoothly conveyed into the limiting mechanism 40. This not only improves the conveying efficiency of the welded pipe device but also further ensures the reliability and consistency of the welding quality.

[0081] Refer to Figure 1 and Figure 6 , in some embodiments of the present invention, the traction mechanism 50 includes a traction assembly 51 and an adjustment assembly 52. The traction assembly 51 is disposed on the frame 10. The traction assembly 51 includes two traction wheels 511 arranged at intervals. The resin hose 1 is configured to be able to pass through between the two traction wheels 511. The traction wheels 511 are configured to be able to traction the resin hose 1 to be conveyed along the conveying direction; the adjustment assembly 52 is disposed on the frame 10. The adjustment assembly 52 includes a fourth driving member 521. One of the traction wheels 511 is disposed on the frame 10, and the other traction wheel 511 is disposed at the output end of the fourth driving member 521. The fourth driving member 521 is configured to be able to drive the traction wheel 511 to move so as to adjust the distance between the two traction wheels 511.

[0082] Specifically, the core component of the traction mechanism 50 is the traction assembly 51, which is firmly mounted on the frame 10. The traction assembly 51 includes two traction wheels 511 arranged at intervals. The space between the two traction wheels 511 just allows the resin hose 1 to pass through. When the resin hose 1 is placed between the two traction wheels 511, the traction wheels 511 are configured to be able to tightly clamp the resin hose 1 and traction the resin hose 1 to move forward along the conveying direction through its rotational movement. In order to adapt to resin hoses 1 with different diameters, the traction mechanism 50 is also equipped with an adjustment assembly 52. The adjustment assembly 52 is also mounted on the frame 10 and includes a fourth driving member 521. Among them, one traction wheel 511 is fixed on the frame 10 as a fixed wheel, and the other traction wheel 511 is mounted on the output end of the fourth driving member 521 as a movable wheel. When it is necessary to adjust the distance between the two traction wheels 511, just start the fourth driving member 521, and the movable wheel can be driven to move on the frame 10. By changing the position of the movable wheel, the distance between the two traction wheels 511 can be easily adjusted to adapt to resin hoses 1 with different diameters; in addition, by adjusting the distance between the two traction wheels 511, the clamping force of the two traction wheels 511 on the resin hose 1 can also be adjusted, so as to achieve the purpose of controlling the conveying speed and adjusting the clamping and welding time. This design not only improves the versatility of the welded pipe device but also ensures the stability and accuracy of the resin hose 1 during the conveying process.

[0083] According to an embodiment of the second aspect of the present invention, a welded pipe device (not shown in the figure), the welded pipe device includes the welded pipe device according to any one of the embodiments of the first aspect above.

[0084] Specifically, in addition to including the welded pipe device according to the embodiments of the first aspect, the welded pipe device may further include a feeding reel for feeding the resin hose 1. The resin hose 1 is released from the feeding reel and conveyed into the welded pipe device. In the welded pipe device, key components such as a tensioning assembly 21, a feeding mechanism 20, a traction mechanism 50, and a limiting mechanism 40 are installed on the frame 10. The tensioning assembly 21 is responsible for maintaining an appropriate tension of the resin hose 1 to ensure that it will not be slack or too tight during transportation; the feeding mechanism 20, through the cooperation of the tensioning assembly 21, the third limiting assembly 22, and the guiding assembly 23, stably conveys the resin hose 1 to the welding position; the traction mechanism 50 utilizes the cooperation of the traction assembly 51 and the adjusting assembly 52 to achieve controllable traction and pitch adjustment of the resin hose 1; and the limiting mechanism 40 ensures that the resin hose 1 maintains the correct position during the welding process.

[0085] In addition, the welded pipe device may also be equipped with a control system for precisely controlling the operation of each component to achieve an automated and intelligent welding process. Therefore, it can be imagined that the welded pipe device according to the embodiments of the present invention has at least the following beneficial effects: Through the welded pipe device, the welded pipe device can be conveyed in the feeding mechanism 20 and the limiting mechanism 40 by the traction of the traction mechanism 50. During the conveying process, the welding end of the welding mechanism 30 heats the intersection between the two resin hoses 1, causing the welding part on the surface of the resin hose 1 to melt, facilitating the mutual adhesion of the resin hoses 1 in the limiting mechanism 40, and thus realizing the welding of the resin hoses 1. In the limiting mechanism 40, the first limiting wheel 412 restricts and presses the two resin hoses 1 in the first limiting groove 4121, facilitating the mutual fusion and adhesion of the two resin hoses 1, thereby realizing the automated welding of the resin hoses 1, and further improving the production efficiency and reducing the labor cost.

[0086] The embodiments of the present invention have been described in detail above with reference to the drawings, but the present invention is not limited to the above embodiments. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those of ordinary skill in the art.
