Description

Technical Field

[0001] This application belongs to the technical field of hot melt welding machines, and particularly relates to a hot melt welding machine. Background Technology

[0002] Thermofusion welding of pipes involves heating the welding ends of two pipes to a molten state using a heating tool, removing the heating tool, and quickly pressing the two molten welding ends together. A specified pressure is applied and maintained at this pressure for a certain period of time. After sufficient cooling to room temperature, the welding ends of the pipes are connected and fused together to form a compliant thermofusion welded joint. Before welding, the pipe ends often need to be trimmed and ground.

[0003] Patent CN114834056B discloses a fully automatic hot melt welding machine, including a frame, a hydraulic cylinder one, a sliding platform, a hydraulic cylinder two, a milling heating device frame, connecting pipes, a milling heating device, a movable clamping device, a fixed clamping device, a constant temperature pumping device, a control workstation, and a sliding platform spring; the milling heating device includes a pipe interface, a cutter head, a gear ring, internal pipes, connecting holes, a motor, an annular groove, gears, a support rod, a milling heating device housing, a liquid-conducting bushing, a liquid-conducting shaft, and a liquid-conducting hole; the cutter head has a liquid-guiding groove inside.

[0004] The aforementioned patent integrates the heating plate and the milling cutter disc into one unit, eliminating the need for manual switching between them during operation and solving the problem of inconvenient milling cutter switching, thus improving portability. However, in actual use, integrating the two functions together may lead to a higher failure rate due to the complex structure. Failure of any component may affect the operation of the entire system, and the heat and vibration generated by the heating plate and the milling cutter disc during operation may adversely affect each other, causing faster wear of components and accelerating the aging process of the equipment. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this application is to provide a hot melt welding machine that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a hot melt welding machine, comprising:

[0007] frame;

[0008] A clamping device, mounted on a frame, is used to clamp the pipe to be welded;

[0009] A milling device, mounted on a frame, is used to cut off the non-flat ends of the pipe to be welded;

[0010] A heating device, mounted on a frame, is used to heat the pipes to be welded;

[0011] The control workstation connects to and controls the clamping device, milling device, and heating device.

[0012] Both the milling device and the heating device can be detachably mounted on the machine frame.

[0013] The aforementioned hot melt welding machine, by designing the milling device and heating device to be detachably mounted on the frame, employs a modular design that allows for independent inspection, maintenance, and replacement of each component. This significantly reduces the risk of system downtime due to a single component failure, thereby improving the overall reliability and stability of the equipment. It also avoids the potential for heat and vibration to adversely affect each other if the heating plate and milling cutter are integrated together. Furthermore, the hot melt welding machine of this application separates these two functional components, reducing their mutual interference during operation, thus extending the service life of the components and slowing down the aging process of the equipment.

[0014] Meanwhile, the modular design makes maintenance and upgrades simpler and more efficient. When a component malfunctions or needs upgrading, users only need to replace or upgrade that component, without having to perform a full overhaul or replacement of the entire device. This reduces maintenance costs and shortens equipment downtime.

[0015] In use, the two pipes to be welded are fixed to the clamping device. The welding ends of the two pipes are milled by the milling device to ensure that the welding end face is flat. Then the milling device is removed and the heating device is installed to heat the welding end face. After heating, the heating device is removed. Finally, the two pipes are driven close together by the clamping device to complete the welding.

[0016] Furthermore, the clamping device includes:

[0017] The drive assembly includes a fixed rod and a sliding cylinder that can slide on the fixed rod, with the fixed rod provided on both sides of the frame;

[0018] A clamping seat is used to fix a pipe, including a stationary seat and a movable seat. The stationary seat is located at the end of the fixing rod away from the sliding cylinder, and the movable seat is located on the sliding cylinder.

[0019] The sliding cylinder is connected to a pipe, which allows it to move left and right on the fixed rod by pressurizing and depressurizing. When pressurizing, the sliding cylinder moves the moving seat closer to the stationary seat, and when depressurizing, the sliding cylinder moves the moving seat away from the stationary seat.

[0020] Fixed rods are installed on both sides of the frame, serving as tracks and support structures for the sliding cylinder. The sliding cylinder can slide on the fixed rods, moving left and right by pressurizing and depressurizing the pipeline. A stationary seat is located at the end of the fixed rod furthest from the sliding cylinder, serving as a fixed point for clamping the pipeline. A movable seat is located on the sliding cylinder and moves with it, serving as another variable point for clamping the pipeline.

[0021] When the pipeline is pressurized, the sliding cylinder, under pressure, moves along the fixed rod towards the stationary seat. During this process, the moving seat on the sliding cylinder gradually approaches the stationary seat until the pipeline between them contacts. When the pipeline is depressurized, it moves away from the stationary seat along the fixed rod. During this process, the moving seat gradually moves away from the stationary seat. Two pipelines are installed here, connected to the control workstation, and the movement of the sliding cylinder is controlled by pressurization and depressurization.

[0022] The movement of the sliding cylinder is controlled by pressurizing and depressurizing the pipeline, thereby moving the two pipelines closer and further apart. The movement of the milling device and the heating device is also controlled. The milling device and the heating device are installed between the stationary body and the moving body during use. The movement of the moving body can drive the milling device and the heating device to gradually move closer to the stationary body, thereby completing the milling and heating of the two pipelines. This control method is flexible and easy to automate.

[0023] Furthermore: the stationary seat body includes:

[0024] The first support structure includes a first lower support seat and a first upper support seat, which are fixed together by fasteners;

[0025] The first clamping structure includes a first lower clamping member and a first upper clamping member, and the first lower clamping member and the first upper clamping member are respectively provided with a lower clamping port and an upper clamping port adapted to the pipeline;

[0026] The first lower clamping member is disposed on the first lower support base, the first upper clamping member is disposed on the first upper support base, and both the first support structure and the first clamping structure are provided in two sets.

[0027] The first lower support serves as the bottom support of the stationary seat, providing stability and strength. The first upper support is located above the first lower support and is fixedly connected to it via fasteners (here, hinged bolts), together forming the main support portion of the stationary seat. A first lower clamping member is mounted on the first lower support and has a lower clamping port adapted to the pipe for clamping it from below. A first upper clamping member is mounted on the first upper support and has an upper clamping port adapted to the pipe for clamping it from above. Furthermore, only the outermost first lower support is connected to the frame, and the two first lower supports are connected by a connecting rod and fasteners.

[0028] The first support structure, through the combination of a first lower support seat and a first upper support seat, provides a stable support foundation, ensuring the overall stability and strength of the stationary base. The first clamping structure, through the combination of a first lower clamping member and a first upper clamping member, achieves clamping of the pipe, further improving the stability and reliability of the clamping. Furthermore, because the clamping opening is arc-shaped, the stationary base can adapt to pipes of different specifications and types, improving the equipment's versatility.

[0029] Furthermore, the movable seat body includes:

[0030] A mounting base is installed on the frame and connected to a fixing rod;

[0031] The second support structure includes a second lower support base and a second upper support base, both of which are also fixed by fasteners;

[0032] The second clamping structure includes a second lower clamping member and a second upper clamping member, and the second lower clamping member and the second upper clamping member are respectively provided with a lower clamping port and an upper clamping port adapted to the pipeline;

[0033] The second lower clamping member is disposed on the second lower support base, the second upper clamping member is disposed on the second upper support base, and both the second support structure and the second clamping structure are provided in two sets.

[0034] The second lower support seat serves as the bottom support for the moving seat body and has the same structure as the first lower support seat of the stationary seat body. The second upper support seat is located above the second lower support seat and is fixedly connected to the second lower support seat by fasteners (here, hinged bolts), together forming the main support part of the moving seat body. The second lower clamping member is mounted on the second lower support seat and has a lower clamping port adapted to the pipe for clamping the pipe from below. The second upper clamping member is mounted on the second upper support seat and has an upper clamping port adapted to the pipe for clamping the pipe from above.

[0035] The second support structure of the moving base is basically the same as the first support structure of the stationary base, except that the second support structure is mounted on the sliding cylinder to accommodate movement requirements. Like the stationary base, the support and clamping structures of the moving base are also designed as detachable and replaceable modules for easy installation, disassembly, and maintenance.

[0036] Furthermore, the milling device includes a support frame, a milling cutter mounted on the support frame, a driver for driving the milling cutter mounted at one end of the support frame, and a limiting pin mounted at the other end of the support frame. The limiting pin cooperates with a fixed rod and can slide on the fixed rod.

[0037] The support frame, as the main structure of the milling device, is used to support and fix other components. The milling cutter, mounted on the support frame, is used to remove the uneven ends of the pipe to be welded, ensuring the flatness and perpendicularity of the pipe end face and providing a good foundation for subsequent welding operations. The driver, located at one end of the support frame, drives the milling cutter to rotate for the milling process of the pipe.

[0038] In its initial state, the milling device is engaged with the fixed rod by a limiting pin and held in a certain position. At this time, the milling cutter maintains a certain distance from the pipe to be processed. When the moving base moves, it pushes the milling device to slide along the fixed rod, gradually approaching the stationary base. During this process, the limiting pin slides on the fixed rod, serving as a guide and limiting pin. When the milling device moves to the appropriate position, the driver starts, driving the milling cutter to rotate and feed, simultaneously milling the pipe on both the stationary and moving bases. During milling, the milling cutter removes the non-flat ends of the pipe, forming a flat end face. After milling is completed, the driver stops working, and the milling device can then be removed.

[0039] The milling unit features a modular design, incorporating components such as a support frame, milling cutter, driver, and limit pins, facilitating installation, disassembly, and maintenance. Furthermore, the milling unit can simultaneously mill pipes on both the stationary and moving bases, improving work efficiency and machining quality. The limit pin design ensures the milling unit will not detach or wobble during movement, enhancing the equipment's safety and stability.

[0040] Furthermore, the heating device includes a grip handle, a connecting plate connected to the grip handle, a heating plate connected to the connecting plate, and limiting protrusions on both sides of the heating plate. The limiting protrusions are provided with grooves that cooperate with the fixing rods, and the heating device can be mounted on the two fixing rods through the grooves.

[0041] The handle serves as the operating part of the heating device, making it easy for users to grip and move. The connecting plate connects the handle and the heating plate, providing support. The heating plate, as the core component of the heating device, is used to heat the pipes. Limiting protrusions are located on both sides of the heating plate, and the grooves on the limiting protrusions cooperate with the fixing rods, allowing the heating device to be mounted on the two fixing rods and moved along them.

[0042] In use, align the groove on the limiting protrusion of the heating device with the fixing rod, and mount the heating device on the two fixing rods. At this time, the heating plate maintains a certain distance from the pipe to be heated. When the moving base moves, it can push the heating device to slide along the fixing rod, gradually approaching the stationary base. During this process, the limiting protrusion and groove act as guides and limits, ensuring the stability and accuracy of the heating device during movement. When the heating device moves to the appropriate position, it heats the pipes on both the stationary and moving bases to the temperature required for welding. After heating is complete, turn off the heating plate. Drive the pipes back towards the stationary base via the moving base, bringing the two heated pipes into contact. During contact, since the pipes have been heated to the required welding temperature, they will quickly melt and fuse together, completing the weld.

[0043] The heating device features a modular design, incorporating a handle, connecting plate, heating plate, and limiting protrusions, facilitating installation, disassembly, and maintenance. It can heat two pipes simultaneously, improving efficiency and heating quality. Furthermore, because the heating plate directly heats the pipes, the heating speed is rapid, reducing waiting time.

[0044] The beneficial effects of this application are:

[0045] 1. By designing the milling and heating devices to be detachably mounted on the frame, this modular design allows for independent inspection, maintenance, and replacement of each component. This significantly reduces the risk of system downtime due to a single component failure, thereby improving the overall reliability and stability of the equipment. It also avoids the potential for heat and vibration to adversely affect each other if the heating plate and milling cutter are integrated together.

[0046] 2. Modular design makes maintenance and upgrades simpler and more efficient. When a component malfunctions or needs upgrading, the user only needs to replace or upgrade that component, without requiring a complete overhaul or replacement of the entire device. This reduces maintenance costs and shortens equipment downtime.

[0047] 3. When using the device, fix the two pipes to be welded onto the clamping device, and use the milling device to mill the welding ends of the two pipes to ensure that the welding end face is flat. Then remove the milling device and install the heating device to heat the welding end face. After heating, remove the heating device, and finally use the clamping device to drive the two pipes closer together to complete the welding. Attached Figure Description

[0053] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0054] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0055] The hot melt welding machine provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0056] Example 1:

[0057] like Figures 1 to 4 As shown, this application provides a hot melt welding machine, including:

[0058] 100 racks;

[0059] A clamping device 200 is mounted on the frame 100 and is used to clamp the pipe 213 to be welded;

[0060] A milling device 300, mounted on a frame 100, is used to cut off the non-flat ends of the pipe 213 to be welded;

[0061] A heating device 400 is mounted on a frame 100 and is used to heat the pipe 213 to be welded;

[0062] The control workstation 500 connects to and controls the clamping device 200, the milling device 300, and the heating device 400;

[0063] The milling device 300 and the heating device 400 are both detachably mounted on the frame 100.

[0064] In some embodiments of this application, such as Figure 1 As shown, the aforementioned hot melt welding machine, by detachably mounting the milling device 300 and heating device 400 on the frame 100, employs a modular design that allows for independent inspection, maintenance, and replacement of each component. This significantly reduces the risk of system downtime due to component failure, thereby improving the overall reliability and stability of the equipment. It also avoids the potential for heat and vibration to adversely affect the heating plate 430 and milling cutter disc if they were integrated together. Furthermore, the hot melt welding machine of this application separates these two functional components, reducing their mutual influence during operation, thus extending the service life of the components and slowing down the aging process of the equipment.

[0065] Meanwhile, the modular design makes maintenance and upgrades simpler and more efficient. When a component malfunctions or needs upgrading, users only need to replace or upgrade that component, without having to perform a full overhaul or replacement of the entire device. This reduces maintenance costs and shortens equipment downtime.

[0066] In use, the two pipes 213 to be welded are fixed to the clamping device 200. The welding ends of the two pipes 213 are milled by the milling device 300 to ensure that the welding end face is flat. Then the milling device 300 is removed and the heating device 400 is installed to heat the welding end face. After heating, the heating device 400 is removed. Finally, the two pipes 213 are driven close together by the clamping device 200 to complete the welding.

[0067] Example 2:

[0068] This application provides a hot melt welding machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0069] like Figure 1 and Figure 2 As shown, the clamping device 200 includes:

[0070] The drive assembly 210 includes a fixed rod 211 and a sliding cylinder 212 that can slide on the fixed rod 211. The fixed rod 211 is provided on both sides of the frame 100.

[0071] A clamping seat for fixing pipe 213 includes a stationary seat 220 and a movable seat 230. The stationary seat 220 is disposed at the end of the fixing rod 211 away from the sliding cylinder 212, and the movable seat 230 is disposed on the sliding cylinder 212.

[0072] The sliding cylinder 212 is connected to the pipe 213. It can move left and right on the fixed rod 211 by pressurizing and depressurizing through the pipe 213. When pressurizing, the sliding cylinder 212 drives the moving seat 230 to move closer to the stationary seat 220. When depressurizing, the sliding cylinder 212 drives the moving seat 230 away from the stationary seat 220.

[0073] In this embodiment, fixed rods 211 are provided on both sides of the frame 100, serving as tracks and support structures for the sliding cylinder 212. The sliding cylinder 212 can slide on the fixed rods 211 and move left and right through pressurization and depressurization via the pipe 213. A stationary seat 220 is provided at the end of the fixed rod 211 away from the sliding cylinder 212, serving as a fixed point for clamping the pipe 213. A movable seat 230 is provided on the sliding cylinder 212 and moves with the sliding cylinder 212, serving as another variable point for clamping the pipe 213.

[0074] When pipe 213 is pressurized, the sliding cylinder 212 is subjected to pressure and moves along the fixed rod 211 towards the stationary seat 220. During this process, the movable seat 230 on the sliding cylinder 212 gradually approaches the stationary seat 220 until the pipe 213 between them contacts. When pipe 213 is depressurized, it moves along the fixed rod 211 away from the stationary seat 220. During this process, the movable seat 230 gradually moves away from the stationary seat 220. Two pipes 213 are provided and connected to the control workstation 500, controlling the movement of the sliding cylinder 212 through pressurization and depressurization.

[0075] The movement of the sliding cylinder 212 is controlled by pressurizing and depressurizing the pipe 213, thereby enabling the two pipes 213 to move closer and further apart. The movement of the milling device 300 and the heating device 400 is also controlled. The milling device 300 and the heating device 400 are installed between the stationary seat 220 and the moving seat 230 during use. The movement of the moving seat 230 can drive the milling device 300 and the heating device 400 to gradually move closer to the stationary seat 220, thereby completing the milling and heating of the two pipes 213. This control method is flexible and easy to automate.

[0076] Example 3:

[0077] This application provides a hot melt welding machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0078] like Figure 1 and Figure 2 As shown, the stationary body 220 includes:

[0079] The first support structure includes a first lower support 221 and a first upper support 222, which are fixed together by fasteners;

[0080] The first clamping structure includes a first lower clamping member 223 and a first upper clamping member 224, and the first lower clamping member 223 and the first upper clamping member 224 are respectively provided with a lower clamping port 225 and an upper clamping port 226 adapted to the pipe 213.

[0081] The first lower clamping member 223 is disposed on the first lower support 221, the first upper clamping member 224 is disposed on the first upper support 222, and both the first support structure and the first clamping structure are provided in two sets.

[0082] In this embodiment, the first lower support 221 serves as the bottom support of the stationary seat 220, providing stability and strength. The first upper support 222 is located above the first lower support 221 and is fixedly connected to the first lower support 221 via fasteners (here, hinged bolts), together forming the main support portion of the stationary seat 220. The first lower clamping member 223 is disposed on the first lower support 221 and has a lower clamping port 225 adapted to the pipe 213 for clamping the pipe 213 from below. The first upper clamping member 224 is disposed on the first upper support 222 and has an upper clamping port 226 adapted to the pipe 213 for clamping the pipe 213 from above. Furthermore, only the outermost first lower support 222 is connected to the frame 100, and the two first lower support 222s are connected by a connecting rod and fasteners.

[0083] The first support structure, through the combination of the first lower support seat 221 and the first upper support seat 222, provides a stable support foundation, ensuring the overall stability and strength of the stationary seat 220. The first clamping structure, through the combination of the first lower clamping member 223 and the first upper clamping member 224, achieves clamping of the pipe 213, further improving the stability and reliability of the clamping. Furthermore, because the clamping opening is arc-shaped, the stationary seat 220 can adapt to pipes 213 of different specifications and types, improving the versatility of the equipment.

[0084] Furthermore, the moving seat 230 includes:

[0085] A fixed base 235 is mounted on the frame 100 and connected to a fixed rod 211;

[0086] The second support structure includes a second lower support 231 and a second upper support 232, which are also fixed by fasteners;

[0087] The second clamping structure includes a second lower clamping member 233 and a second upper clamping member 234. The second lower clamping member 233 and the second upper clamping member 234 are also respectively provided with a lower clamping port 225 and an upper clamping port 226 adapted to the pipe 213.

[0088] The second lower clamping member 233 is disposed on the second lower support base 231, and the second upper clamping member 234 is disposed on the second upper support base 232. Both the second support structure and the second clamping structure are provided in two sets.

[0089] The second lower support 231 serves as the bottom support of the moving seat 230 and has the same structure as the first lower support 221 of the stationary seat 220. The second upper support 232 is located above the second lower support 231 and is fixedly connected to the second lower support 231 by fasteners (here, hinge bolts), together forming the main support part of the moving seat 230. The second lower clamping member 233 is disposed on the second lower support 231 and has a lower clamping port 225 adapted to the pipe 213 for clamping the pipe 213 from below. The second upper clamping member 234 is disposed on the second upper support 232 and has an upper clamping port 226 adapted to the pipe 213 for clamping the pipe 213 from above.

[0090] The second support structure of the moving base 230 is basically the same as the first support structure of the stationary base 220, except that the second support structure is mounted on the sliding cylinder 212 to accommodate movement requirements. Like the stationary base 220, the support structure and clamping structure of the moving base 230 are also designed as detachable and replaceable modules for easy installation, disassembly and maintenance.

[0091] Example 4:

[0092] This application provides a hot melt welding machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0093] like Figure 4 As shown, the milling device 300 includes a support frame 310, a milling cutter 320 disposed on the support frame 310, a driver 330 disposed at one end of the support frame 310 for driving the milling cutter 320, and a limiting pin 340 disposed at the other end of the support frame 310. The limiting pin 340 cooperates with the fixing rod 211 and can slide on the fixing rod 211.

[0094] In this embodiment, the device is fixed on the fixing rod 211 and can slide on the fixing rod 211 even when it falls off. When the moving seat 230 moves, it can push the milling device 300 to move, gradually bringing it closer to the stationary seat 220, so that the pipe 213 on the stationary seat 220 and the moving seat 230 can be milled simultaneously.

[0095] The support frame 310 serves as the main structure of the milling device 300, supporting and fixing other components. The milling cutter 320 is mounted on the support frame 310 and is used to cut off the non-flat ends of the pipe 213 to be welded, ensuring the flatness and perpendicularity of the pipe 213 end face, providing a good foundation for subsequent welding operations. The driver 330 is located at one end of the support frame 310 and is used to drive the milling cutter 320 to rotate, performing the milling process on the pipe 213.

[0096] In its initial state, the milling device 300 is engaged with the fixed rod 211 via the limiting pin 340 and held in a certain position. At this time, the milling cutter 320 maintains a certain distance from the pipe 213 to be processed. When the moving base 230 moves, it pushes the milling device 300 to slide along the fixed rod 211, gradually approaching the stationary base 220. During this process, the limiting pin 340 slides on the fixed rod 211, serving as a guide and limiter. When the milling device 300 moves to the appropriate position, the driver 330 starts, driving the milling cutter 320 to rotate and feed, simultaneously milling the pipe 213 on both the stationary base 220 and the moving base 230. During milling, the milling cutter 320 removes the non-flat ends of the pipe 213, forming a flat end face. After milling is completed, the driver 330 stops working, and the milling device 300 can then be removed.

[0097] The milling device 300 achieves a modular design through the combination of components such as the support frame 310, milling cutter 320, driver 330, and limit pin 340, facilitating installation, disassembly, and maintenance. Furthermore, the milling device 300 can simultaneously mill the pipe 213 on both the stationary seat 220 and the moving seat 230, improving work efficiency and processing quality. The design of the limit pin 340 ensures that the milling device 300 will not fall off or shake during movement, improving the safety and stability of the equipment.

[0098] Example 5:

[0099] This application provides a hot melt welding machine, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0100] like Figure 3 As shown, the heating device 400 includes a handle 410, a connecting plate 420 connected to the handle 410, a heating plate 430 connected to the connecting plate 420, and limiting protrusions 440 provided on both sides of the heating plate 430. The limiting protrusions 440 are provided with grooves 450 that cooperate with the fixing rods 211. The heating device 400 can be mounted on the two fixing rods 211 through the grooves 450.

[0101] In this embodiment, the handle 410 serves as the operating part of the heating device 400, facilitating user gripping and movement of the heating device 400. The connecting plate 420 connects the handle 410 and the heating plate 430, providing support. The heating plate 430, as the core component of the heating device 400, is used to heat the pipe 213. Limiting protrusions 440 are provided on both sides of the heating plate 430, and the grooves 450 on the limiting protrusions 440 cooperate with the fixing rods 211, allowing the heating device 400 to be mounted on the two fixing rods 211 and to move on the fixing rods 211.

[0102] In use, align the groove 450 on the limiting protrusion 440 of the heating device 400 with the fixing rod 211, and mount the heating device 400 on the two fixing rods 211. At this time, the heating plate 430 maintains a certain distance from the pipe 213 to be heated. When the moving base 230 moves, it can push the heating device 400 to slide along the fixing rod 211, gradually approaching the stationary base 220. During this process, the limiting protrusion 440 and the groove 450 play a guiding and limiting role, ensuring the stability and accuracy of the heating device 400 during movement. When the heating device 400 moves to the appropriate position, it heats the pipe 213 on the stationary base 220 and the moving base 230 to reach the temperature required for welding. After heating is completed, turn off the heating plate 430. Drive the pipe 213 back towards the stationary base 220 via the moving base 230, so that the two heated pipes 213 come into contact. During the contact process, since the pipes 213 have been heated to the temperature required for welding, they will quickly melt and fuse together to complete the welding.

[0103] The heating device 400 achieves a modular design through the combination of components such as the handle 410, connecting plate 420, heating plate 430, and limiting protrusion 440, facilitating installation, disassembly, and maintenance. The heating device 400 can simultaneously heat two pipes 213, improving work efficiency and heating quality. Furthermore, because the heating plate 430 directly heats the pipes 213, the heating speed is faster, reducing waiting time.
