Description

Technical Field

[0001] This application relates to the field of hot melt welding equipment technology, and in particular to a hot melt welding equipment for processing multi-way valves. Background Technology

[0002] Multi-way valves, as key control components in hydraulic systems, are widely used in construction machinery, agricultural machinery, and industrial automation equipment. During the manufacturing process of multi-way valves, the valve body is often fixedly connected to external pipelines via hot-melt welding to ensure the sealing and structural strength of the connection. Hot-melt welding is a process that uses heating elements to heat the pipes and the ends of the multi-way valve to be welded to a molten state, and then applies pressure to bond the two together.

[0003] Currently, before hot-melt welding, the ends of the pipes and interfaces of multi-way valves to be welded must be cleaned to remove surface oil, oxide layers, burrs, dust, and other impurities. If cleaning is incomplete, the weld interface will suffer from defects such as porosity, incomplete welds, or insufficient bond strength due to the presence of impurities, severely affecting weld quality and service life. In existing technologies, the cleaning process mostly involves manual wiping and blowing with hand-held brushes or air guns, which has the following shortcomings: In existing hot melt welding equipment, the cleaning and welding processes are usually performed separately. The pipes are first cleaned at a dedicated cleaning station, and then transferred to the welding station for welding. This step-by-step operation not only increases process flow time and reduces production efficiency, but also makes the pipe ends susceptible to re-contamination during the transfer process, causing the previous cleaning work to fail. Furthermore, multi-way valves come in many models and specifications, and different models connect to pipes of varying diameters and lengths. This requires the cleaning mechanism of the hot melt welding equipment to adapt to the cleaning needs of different pipe specifications. When pipe specifications change, it is often necessary to replace the cleaning brush, adjust the clamps, or even replace the entire cleaning assembly. This changeover is time-consuming and cumbersome, severely impacting the equipment's versatility and the production line's flexibility. Therefore, this paper proposes a hot melt welding equipment for multi-way valve processing to address the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies and improve welding results, this application provides a hot-melt welding device for processing multi-way valves. This device has the advantages of efficient cleaning of pipe ends before hot-melt welding, timely removal of debris, and good adjustability, thus solving the problems mentioned above.

[0005] This application provides a hot melt welding device for processing multi-way valves, which adopts the following technical solution: A hot melt welding device for processing multi-way valves includes a hot melt welding pipe mounted on a machine base. The machine base is provided with a loading mechanism one and a loading mechanism two, wherein the loading mechanism one and the loading mechanism two are respectively used to load and clamp the pipe and the multi-way valve. The machine base is also provided with a cleaning mechanism. The cleaning mechanism consists of a cleaning component and a pressurizing component, and a connecting arm is provided between the cleaning component and the pressurizing component. The loading mechanism 2 is provided with a top rod for use with the cleaning component, and an abutment block is detachably installed at the end of the top rod.

The cleaning component includes a lifting rod that slides through the inside of the cleaning tube, a cleaning clamp fixed to one end of the lifting rod, and a ball bearing rotatably mounted on the other end of the lifting rod. A return spring is wound around the outer surface of the lifting rod, and a guide sleeve is sleeved on the outer surface of the cleaning tube. The abutting block abuts against the guide sleeve. A cleaning brush is also provided inside the cleaning tube. The guide sleeve is provided with guide surface one, guide surface two and guide surface three. The guide sleeve is driven to move along the cleaning pipe axis by the abutting block abutting with the guide sleeve, thereby driving the cleaning component. In conjunction with the use of the cleaning brush, the pipe is cleaned.

[0006] Optionally: The hot-melt welded pipe is located between the first loading mechanism and the second loading mechanism. The first loading mechanism includes a linear module and a linear module, wherein the linear module and the linear module are distributed in the X and Y axis directions, and the linear module is slidably connected to the base.

[0007] Optionally: A lifting platform is installed on the top side of the linear module two, a vertical plate is welded to the top side of the lifting platform, a mounting base is fixed on the outer wall of the vertical plate, and a locking rod is installed on the internal thread of the mounting base.

[0008] Optionally: The loading mechanism two includes a linear module three that is slidably mounted on the base. The top side of the linear module three is provided with a clamping assembly. The clamping assembly includes a clamping frame. The interior of the clamping frame is hollow and has two symmetrically distributed clamping blocks inside.

[0009] Optionally, the clamping assembly further includes a dual-axis cylinder fixed to the top side of the clamping frame. Both output ends of the dual-axis cylinder are fixed with connecting rods, and the ends of the two connecting rods are respectively fixed to the outer walls of the two clamping blocks. One end of the push rod is threadedly connected to the clamping frame.

[0010] Optionally: Both the cleaning tube and the guide sleeve are hollow inside, and the guide sleeve is fitted on the outer surface of the cleaning tube. One end of the cleaning tube is fixed to the end of the hot melt welding tube, and a return spring is installed between the guide sleeve and the end of the cleaning tube.

[0011] Optionally: The guide surface one, guide surface two, and guide surface three are distributed from left to right. Guide surface one is a straight surface, guide surface two is an inclined surface, and guide surface three is a wavy surface. When the guide sleeve is displaced, the cleaning component will produce different movement actions through the guidance of guide surface one, guide surface two, and guide surface three. At the same time, the triggering time of the cleaning component can be adjusted by adjusting the position of the push rod.

[0012] Optionally: the cleaning clamp is arc-shaped, and the number of cleaning components is three, with the three cleaning components distributed equidistantly in a ring.

[0013] Optionally: The pressurizing component includes a hollow pressurizing cylinder, and a piston extending outward is slidably disposed inside the pressurizing cylinder. One end of the piston is fixed to the connecting arm, and the other end of the connecting arm is fixed to the outer wall of the guide sleeve.

[0014] Optionally, the pressurizing component further includes a suction pipe disposed inside the cleaning pipe, a valve pipe is installed on the outer wall of the pressurizing cylinder, and a connecting pipe is installed between the valve pipe and the suction pipe.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. In this invention, when the pipe enters the cleaning tube, the internal cleaning brush can directly wipe the outer wall of the pipe, effectively removing floating dust, oil stains and tiny burrs from the outer wall, providing multi-dimensional mechanical cleaning of the outer wall; the cleaning clamp, driven by the guide sleeve, sequentially completes three actions: clamping, telescopic, and axial reciprocating oscillation, which, together with the cleaning brush, form a cleaning effect of internal and external clamping, ensuring that there is no residual oxide layer or impurities at the pipe end, including the end face and the transition area of ​​the outer wall, providing a highly clean bonding surface for hot melt welding.

[0016] 2. In this invention, when the guide sleeve moves, the piston of the pressurizing component is driven synchronously by the connecting arm, which automatically generates negative pressure. The suction tube sucks away the debris, oxide scale scraped off by the cleaning clamp and the dust swept off by the cleaning brush in real time. The negative pressure dust suction and mechanical cleaning action are completely synchronized, without the need to start the fan separately or clean manually. Moreover, the sucked-in material is temporarily stored in the suction tube to prevent debris from splashing onto the hot melt welding pipe or welding area, thus ensuring the welding quality.

[0017] 3. In this invention, the push rod is threadedly connected to the clamping frame. By adjusting the extension length of the push rod, the initial contact position between the abutment block and the guide sleeve can be changed, thereby controlling the triggering time and cleaning stroke of the cleaning component. The guide surface is set as a wave-shaped line, which can generate wave motion with different frequencies and amplitudes to adapt to the cleaning needs of pipes of different materials, avoiding damage to soft pipes or forceful removal of hard oxide layers.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0021] This application discloses a hot-melt welding device for processing multi-way valves, including a hot-melt welding pipe 2 mounted on a base 1. The base 1 is equipped with a first loading mechanism 3 and a second loading mechanism 4, which are used to load and clamp the pipe and the multi-way valve, respectively. The hot-melt welding pipe 2 is located between the first loading mechanism 3 and the second loading mechanism 4. A cleaning mechanism 5 is also provided on the base 1. It should be noted that the inner wall of the hot-melt welded pipe 2 is uniformly wound with high-temperature resistant nickel-chromium resistance wire, and the outer layer of the resistance wire is wrapped with a high-temperature resistant insulation layer to prevent short circuits. It is also equipped with a K-type temperature sensor, installed in the middle of the inner wall of the pipe, to collect the heating temperature in real time. It is connected to an XMTD-7000 temperature controller, which can adjust the temperature between 150-250℃. In addition, it is equipped with an overheat protection device with a preset overheat protection temperature of 280℃. When the temperature reaches the protection value, it will automatically cut off the power supply. The outer wall is wrapped with a 10mm thick ceramic fiber insulation layer, and the insulation layer is wrapped with a stainless steel protective shell, which reduces heat loss and extends the service life of the equipment.

[0022] In this embodiment, the loading mechanism 3 includes a linear module 31 and a linear module 32, which are distributed along the X and Y axes, respectively, and the linear module 31 is slidably connected to the base 1. A lifting platform 33 is mounted on the top side of the linear module 32, and a vertical plate 34 is welded to the top side of the lifting platform 33. A mounting seat 35 is fixed on the outer wall of the vertical plate 34, and a locking rod 36 is threaded into the internal part of the mounting seat 35. Through the linkage of the linear module 31 and the linear module 32, the pipeline can be moved in a dual-axis manner in the horizontal plane, and the precise alignment of the pipeline with the hot-melt welded pipe 2 is achieved in conjunction with the lifting platform 33. The locking rod 36 is used to press and fix the end of the pipeline onto the mounting seat 35.

[0023] The loading mechanism 2 4 includes a linear module 3 41 slidably mounted on the base 1, and a clamping assembly 42 is provided on the top side of the linear module 3 41. The clamping assembly 42 includes a clamping frame 421, which is hollow inside and has two symmetrically distributed clamping blocks 422 inside. Specifically, the clamping assembly 42 also includes a dual-axis cylinder 423 fixed to the top side of the clamping frame 421. Both output ends of the dual-axis cylinder 423 are fixed with connecting rods 424, and the ends of the two connecting rods 424 are respectively fixed to the outer walls of the two clamping blocks 422. The dual-axis cylinder 423 drives two clamping blocks 422 to move synchronously in opposite directions or in opposite directions via a connecting rod 424, thereby achieving rapid clamping or release of the multi-way valve housing. The loading mechanism 4 is equipped with a push rod 425 for use with the cleaning assembly 51. A stop block 426 is detachably installed at the end of the push rod 425. It should be noted that one end of the push rod 425 is threadedly connected to the clamping frame 421, and its extension length beyond the clamping frame 421 can be adjusted by rotating the push rod 425. The stop block 426 is preferably made of wear-resistant rubber or polyurethane material to reduce impact noise and extend service life. Furthermore, the threaded push rod 425 allows for flexible adjustment of its extension length, thereby changing the triggering timing and stroke range of the guide sleeve 514, enabling the equipment to adapt to the cleaning needs of pipes of different diameters and lengths, significantly improving the equipment's versatility and ease of adjustment.

[0024] The cleaning mechanism 5 consists of a cleaning assembly 51 and a pressurizing component 52, with a connecting arm 53 between them. Specifically, the cleaning assembly 51 includes a hollow cleaning tube 511, inside which a cleaning component 512 is installed. The cleaning component 512 includes a lifting rod 5121 that slides through the cleaning tube 511, a cleaning clamping plate 5123 fixed to one end of the lifting rod 5121, and a ball bearing 5122 rotatably mounted to the other end of the lifting rod 5121. A return spring 5124 is wound around the outer surface of the lifting rod 5121, which is used to push the lifting rod 5121 and the cleaning clamping plate 5123 back to their original positions after cleaning. A guide sleeve 514 is sleeved on the outer surface of the cleaning tube 511, and an abutment block 426 abuts against the guide sleeve 514. The cleaning tube 511 is also equipped with a cleaning brush 513, which can be made of nylon or metal wire and is arranged circumferentially along the inner wall of the cleaning tube 511.

[0025] In this embodiment, the guide sleeve 514 is internally provided with guide surface one 5141, guide surface two 5142, and guide surface three 5143. Specifically, guide surface one 5141 is a straight surface, guide surface two 5142 is an inclined surface, and guide surface three 5143 is a wavy surface, and guide surfaces one 5141, guide surface two 5142, and guide surface three 5143 are distributed sequentially from left to right. When the guide sleeve 514 is displaced, the ball bearing 5122 rolls and contacts guide surface one 5141, guide surface two 5142, and guide surface three 5143 in sequence, thereby causing the cleaning component 512 to produce different movement actions: at guide surface one 5141, the cleaning clamp 5123 maintains its initial height; at guide surface two 5142, the cleaning clamp 5123 gradually moves closer to the outer wall of the pipe and finally clamps; at guide surface three 5143, the cleaning clamp 5123 produces axial reciprocating micro-movements, which, together with the cleaning brush 513, achieves a combined cleaning effect of scraping and brushing. By adjusting the screw-in depth of the push rod 425, the initial contact position between the abutment block 426 and the guide sleeve 514 can be changed, thereby adjusting the triggering timing of the cleaning component 512 to adapt to pipe end faces of different lengths or diameters; at the same time, the guide surface 5143 can drive the cleaning clamp 5123 to reciprocate, thereby causing the cleaning clamp 5123 to vibrate and shake off the impurities on it.

[0026] It should be noted that both the cleaning tube 511 and the guide sleeve 514 are hollow inside, and the guide sleeve 514 is fitted onto the outer surface of the cleaning tube 511. One end of the cleaning tube 511 is fixed to the end of the hot-melt welding tube 2. A return spring 515 is installed between the guide sleeve 514 and the end of the cleaning tube 511. The return spring 515 pushes the guide sleeve 514 to return to its original position after the push rod 425 disengages from the guide sleeve 514.

[0027] As a further preferred embodiment, the cleaning clamp 5123 is arc-shaped, and its inner arc surface can be equipped with rubber pads or fine serrations to enhance the friction against the outer wall of the pipe and prevent damage. There are three cleaning components 512, which are equidistantly distributed in a ring to create a uniform clamping force on the pipe end.

[0028] In this embodiment, the pressurizing component 52 includes a hollow pressurizing cylinder 521, which is fixedly installed. A piston 522 is slidably installed inside the pressurizing cylinder 521, extending outwards. One end of the piston 522 is fixed to a connecting arm 53, and the other end of the connecting arm 53 is fixed to the outer wall of the guide sleeve 514. The pressurizing component 52 also includes a suction tube 524 disposed inside the cleaning tube 511, with its inlet end extending to the vicinity of the cleaning brush 513. A valve tube 523 is installed on the outer wall of the pressurizing cylinder 521, and a connecting tube 525 is installed between the valve tube 523 and the suction tube 524. When the guide sleeve 514 is moved by the push rod 425, the connecting arm 53 simultaneously pulls the piston 522, creating a negative pressure inside the pressure cylinder 521. This negative pressure is transmitted sequentially through the valve pipe 523 and the connecting pipe 525 to the inlet end of the suction pipe 524, thereby drawing debris and dust generated during the cleaning process into the pressure cylinder 521 for temporary storage. A one-way valve can be installed inside the valve pipe 523 to prevent backflow of airflow. It should be noted that an external connecting pipe can also be installed on the outer wall of the suction pipe 524 for the discharge and collection of the sucked-up impurities.

[0029] Combined with appendix Figures 1-6 The working principle of the above embodiments is as follows: In the initial state, the operator puts the multi-way valve housing into the mounting base 35 and tightens the locking rod 36. Then, the pipe is placed in the clamping frame 421, and the dual-axis cylinder 423 is activated to clamp it through the clamping block 422. Then, the linear module three 41 and the linear module one 31 are activated to send the multi-way valve and the pipe to the welding position in the pipe 2 to be hot melted and welded. First, when the pipe enters the cleaning pipe 511, the cleaning brush 513 inside the cleaning pipe 511 assists in wiping the inner wall of the pipe, achieving comprehensive cleaning of the pipe end. Then, when the loading mechanism 2 4 moves towards the hot-melt welding pipe 2 under the drive of the linear module 3 41, the push rod 425 on its clamping frame 421 drives the end abutment block 426 to move synchronously until the abutment block 426 abuts against the guide sleeve 514 of the cleaning component 51 in the cleaning mechanism 5; the loading mechanism 2 4 continues to be pushed, abutting... The connecting block 426 pushes the guide sleeve 514 to move axially along the cleaning tube 511, compressing the second return spring 515. The guide surfaces 5141, 5142, and 5143 inside the guide sleeve 514 contact the ball bearing 5122 of the cleaning component 512 in sequence. Through the guiding effect of the different guide surfaces, the lifting rod 5121 is driven to slide along the inside of the cleaning tube 511 and compress the first return spring 5124, thereby driving the cleaning clamp 5123 to perform opening, closing, extension and retraction and undulating movements. Simultaneously, when the guide sleeve 514 moves, the piston 522 of the pressurizing component 52 is driven by the connecting arm 53 to slide inside the pressurizing cylinder 521, so that a negative pressure is generated inside the pressurizing cylinder 521. The negative pressure is transmitted to the suction pipe 524 inside the cleaning pipe 511 through the valve pipe 523 and the connecting pipe 525. The suction pipe 524, in conjunction with the mechanical cleaning action of the cleaning clamp 5123, sucks in impurities, oxide layers, etc. at the end of the pipe. At this time, the ends of the pipe and the multi-way valve to be welded are respectively inserted into the hot melt welding pipe 2. The hot melt welding pipe 2 heats up to perform hot melt treatment on the ends of both. After reaching the preset temperature, the pipe and the multi-way valve are driven to approach each other and dock to complete the hot melt welding. Finally, the loading mechanism 1 3 and the loading mechanism 2 4 are released, and the welded multi-way valve assembly is taken out.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
