Description

Technical Field

[0001] The utility model relates to the field of thermoplastic processing, in particular to a plastic pipe welding machine. Background Art

[0002] Plastic pipes are typically made from synthetic resin, typically polyester, with stabilizers, lubricants, and plasticizers added. They are then extruded in a pipe-making machine. Due to their lightweight, corrosion-resistant, aesthetically pleasing appearance, lack of odor, ease of processing, and convenient installation, they are gaining increasing popularity in construction. They are primarily used for piping in building water supply systems, drainage, exhaust, and sewage systems, underground drainage systems, rainwater pipes, and as threading conduit for electrical wiring installations.

[0003] Among non-metallic pipes, plastic pipes are the most widely used. There are many types of plastic pipes, divided into two categories: thermoplastics and thermosetting plastics. Examples of thermoplastics include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and polyoxymethylene (POM), while examples of thermosetting plastics include phenolic plastics. The main advantages of plastic pipes are excellent corrosion resistance, lightweight, easy molding, and ease of processing.

[0004] In current daily life, plastic pipes are widely used. Large-diameter plastic pipes can be welded using plastic pipe welding machines during construction or processing. However, due to the size of small pipes and the variety of accessories, most construction or processing is done by directly sawing the pipes and using accessories and raw tape to connect them. Even if the accessories are cheap, a lot of financial resources will still be wasted when used on a large scale. Therefore, this design provides a hot-melt welding machine for small plastic pipes. By setting up heating components, fastening components and replaceable thermoplastic components, different types of replaceable thermoplastic components can be replaced according to different types of plastic pipes during use, thereby achieving hot-melt welding for different types of plastic pipes. The welding method, the settings of buttons, working indicator lights, temperature detectors, temperature detection lines, and reading screens enable users to manually control the start of the welding machine after connecting to the power supply. At the same time, the user can judge whether it is working normally and whether the temperature for hot-melting plastic pipes has been reached based on the lighting of the working indicator lights and the temperature readings. It can also avoid burns caused by accidental touch. The setting of the detachable support frame allows the welding machine to maintain a horizontal state during heating, so that the plastic pipes can be heated evenly during thermoplastic treatment, which facilitates welding and avoids waste. At the same time, the design is small and compact, and the operation is simple, which makes it easy for users to carry it to different places and use it in narrow environments. It solves the technical problem of how to weld different types of plastic pipes while being easy to carry. Utility Model Content

[0005] The utility model provides a plastic pipe welding machine, which solves the technical problem of how to weld plastic pipes of different models while being easy to carry.

The connecting plate is arranged on the side of the cylindrical handle along the axis of the cylindrical handle, and the side of the connecting plate is fixedly connected to the end face of the cylindrical handle. The wire inlet is arranged on the other end face of the cylindrical handle, and the wire inlet is connected to the inside of the cylindrical handle. The fastening component is arranged on the side of the connecting plate away from the wire inlet, and the fastening component is fixedly connected to the side of the connecting plate away from the wire inlet. The replaceable thermoplastic component is arranged between the fastening components, and the replaceable thermoplastic component is squeezed and fixed by the fastening components. The replaceable thermoplastic component comprises: a cake block, a thermoplastic block for the inner wall of the pipe, and a thermoplastic block for the outer wall of the pipe. The cake block is an iron cylinder, which is arranged vertically, with the axis of the cake block perpendicular to the axis of the cylindrical handle, and the cake block is arranged in the fastening component. The pipe outer wall thermoplastic block is an iron tubular body, with the axis of the pipe outer wall thermoplastic block coinciding with the axis of the cake block, the inner diameter of the pipe outer wall thermoplastic block being the same as the outer diameter of the plastic pipe to be thermoplasticized, the pipe outer wall thermoplastic block being arranged at the center of the circular side of the cake block, and the pipe outer wall thermoplastic block being fixedly connected to the cake block. The pipe inner wall thermoplastic block is an iron cylinder, with the axis of the pipe inner wall thermoplastic block coinciding with the axis of the cake block, the outer diameter of the pipe outer wall thermoplastic block being the same as the inner diameter of the plastic pipe to be thermoplasticized, the pipe inner wall thermoplastic block being arranged at the center of the other circular side of the cake block, and the pipe inner wall thermoplastic block being fixedly connected to the cake block. The heating component is arranged inside the cylindrical handle, the heating component is fixedly connected to the inner wall of the cylindrical handle, and the heating component is electrically connected to the power supply. The temperature detection module is arranged on the cylindrical handle, the temperature detection module is fixedly connected to the cylindrical handle, and the temperature detection module is electrically connected to the heating component.

[0007] When the user wants to perform thermoplastic welding on two plastic pipes of the same model, the user first installs the cake block inside the fastening component, and then powers on the heating component. When the power is turned on, the user waits for the heating component to continuously heat the thermoplastic block on the inner wall of the plastic pipe and the thermoplastic block on the outer wall of the plastic pipe on the cake block inside the fastening component. The user can check the temperature reading of the heating through the temperature detection module. When the temperature reaches the level that can melt the plastic pipe, the user holds the cylindrical handle with one hand, and then holds one end of one of the plastic pipes with the other hand, and inserts the inner wall of the plastic pipe into the outer wall of the thermoplastic block on the inner wall of the pipe, squeezes hard to prevent it from falling off, and then places the plastic pipe welding machine on the ground, and keeps the thermoplastic plastic pipe in a horizontal state, and then picks up the other At one end of the plastic pipe, insert the outer wall of the plastic pipe into the thermoplastic block on the outer wall of the pipe and squeeze it hard. When the hot-melt ends of the two plastic pipes are completed, pull the two plastic pipes out of the hot-melt block on the inner wall of the plastic pipe and the hot-melt block on the outer wall of the plastic pipe, and then insert the end of the plastic pipe with the hot-melt outer wall into the end of the plastic pipe with the hot-melt inner wall, and then apply manpower to keep squeezing. After a period of time, the welding is completed. After the welding is completed, check whether the weld is firm, loose, or deformed. If the above situation occurs, saw off the weld, and then smooth the saw surface and repeat the above hot-melt operation. During the hot-melt period, it is necessary to keep the hot-melt ends of the two plastic pipes close to the thermoplastic block on the outer wall of the plastic pipe and the thermoplastic block on the inner wall of the plastic pipe to prevent loose welding caused by uneven heating.

[0008] Furthermore, the handle further includes a button and an operating indicator light. The button is disposed on the side of the middle portion of the cylindrical handle, is fixedly connected to the cylindrical handle, and is electrically connected to the heating element. The operating indicator light is disposed on the side of the cylindrical handle, adjacent to the button, is fixedly connected to the cylindrical handle, and is electrically connected to the heating element.

[0009] When the user turns on the power to the heating component, the button connected to the heating component on the cylindrical handle can control the start and stop of the heating component. When the button is pressed, the heating component starts heating when the power is on. When the button is pressed again, the heating component stops heating. At the same time, the working indicator light connected to the heating component can emit light when the heating component starts heating, so as to remind the user whether the heating component is in the heating working state, thereby preventing the user from being unable to judge whether the heating component is in the heating state and touching the device, which may cause burns.

[0010] Furthermore, the fastening component includes: a first fastening block, a second fastening block, two semicircular grooves, two locking bolts, four locking ear blocks, and four threaded through holes. The first fastening block is an iron cuboid, which is arranged on the side of the connecting plate away from the cylindrical handle, and the first fastening block is fixedly connected to the connecting plate. The second fastening block is an iron cuboid, which is arranged on the side of the first fastening block away from the connecting plate, and the side of the second fastening block away from the first fastening block is trapezoidal, and the side of the second fastening block away from the trapezoid is the same size as the side of the first fastening block away from the connecting plate, and can fit each other. Two semicircular grooves are respectively arranged on the side of the first fastening block away from the connecting plate and the side of the second fastening block away from the trapezoid. The two semicircular grooves have the same diameter and can form a circle. The circle formed by the two semicircular grooves matches the size of the cake. The four locking lugs are iron cubes, each with a threaded through-hole. They are positioned on either side of the first and second fixing blocks, facing each other. The four locking lugs are fixedly connected to the first and second fixing blocks, respectively. A locking bolt passes through the threaded through-holes of the corresponding two locking lugs and is threadedly engaged therewith.

[0011] When the user wants to install or replace the replaceable thermoplastic component, first, the two locking bolts are respectively inserted into the threaded through holes of the two locking ear blocks provided on both sides of the second fixing block, and then the semicircular groove of the second fixing block is fitted together with the semicircular groove of the first fixing block, so that the two semicircular grooves form a circle, and then the cake block is placed in the circle, and then the two locking bolts are respectively inserted into the threaded through holes of the two locking ear blocks provided on both sides of the first fixing block, and then the two locking bolts are rotated to tightly connect the first fixing block and the second fixing block, and at the same time, the two fixing blocks can be fixed. Since the circle formed by the semicircular grooves fits the size of the cake block, the circle formed by the two semicircular grooves can squeeze and fix the side of the cake block. If you want to replace the replaceable thermoplastic component, first remove the locking bolts in the threaded through holes of the locking ear blocks set on both sides of the first fixing block and the second fixing block, then replace the cake block of different types, and then repeat the above installation operation. Since different specifications of the pipe inner wall thermoplastic components and the pipe outer wall thermoplastic components are set on different cake blocks, the replaceable thermoplastic components can be welded to two plastic pipes of the same specifications of different models.

[0012] Furthermore, the temperature detection module includes a reading screen, a temperature detector, and a temperature detection line. The reading screen is positioned between the button and the operating indicator light, the reading screen being positioned on the outer side of the cylindrical handle and being fixedly connected to the cylindrical handle. The temperature detector is positioned within the cylindrical handle and is fixedly connected to the inner wall of the cylindrical handle. The temperature detector is electrically connected to the reading screen, and the temperature detector is electrically connected to the heating element. One end of the temperature detection line is electrically connected to the temperature detector, and the other end of the temperature detection line is electrically connected to the heating element.

[0013] When the user powers on the heating component and presses a button, the heating component starts heating. When the heating component starts heating, the temperature detection line detects the heat emitted by the heating component and transmits the collected heat data to the temperature detector. The temperature detector then transmits the collected data to the reading screen. At this time, the reading screen will display the current heating temperature of the heating component, so that the user can accurately judge whether the temperature heated by the heating component has reached the level that can be used to heat-melt the plastic pipe.

[0014] Furthermore, the heating component includes: a current amplification module, a heating plate, and a power cord. The current amplification module is arranged inside the cylindrical handle, the current amplification module is fixedly connected to the inner wall of the cylindrical handle, the current amplification module is electrically connected to the button, and the current amplification module is electrically connected to the working indicator light. The heating plate is arranged on the surface of the semicircular groove of the first fixing block, the heating plate is fixedly connected to the surface of the semicircular groove of the first fixing block, the heating plate is electrically connected to the current amplification module, and the heating plate is electrically connected to the other end of the temperature detection line. One end of the power cord is electrically connected to the current amplification module through the line inlet, and the other end of the power cord is electrically connected to the power supply.

[0015] When the user starts to thermoplasticize the pipe, the user first plugs the other end of the power cord into the matching power interface to power the current amplification module. When the current amplification module is powered, the user presses the button on the handle, and the current amplification module begins to amplify the current. At the same time, the working indicator light connected to the current amplification module lights up, indicating that the current amplification module has started current amplification. When the current amplification module starts current operation, the heating plate connected to the current amplification module will continuously heat the cake of the replaceable thermoplastic component under the flow of large current. At the same time, the temperature detection line connected to the heating plate will collect the temperature of the heating plate, and then transmit the temperature data to the temperature detector, and then to the reading screen. The current amplification function of the current amplification module heats the cake through the heating plate, so that the thermoplastic components on the outer wall of the pipe and the thermoplastic components on the inner wall of the pipe can quickly reach the thermoplastic temperature of the plastic pipe.

[0016] Furthermore, the device further includes a removable support frame, which is mounted on the ground and connected to the connecting plate at the top. The removable support frame includes: a support plate, a support rod, and a mounting ring. The support plate is mounted horizontally on the ground. The axis of the support rod is perpendicular to the support plate. The support rod is mounted on the top surface of the middle portion of the support plate, and the lower end of the support rod is fixedly connected to the support plate. The mounting ring is an iron tube. The mounting ring has the same shape as the connecting plate, and the inner diameter of the mounting ring matches the outer diameter of the connecting plate. The mounting ring is mounted on the top of the support rod, fixedly connected to the support rod, and is sleeved outside the connecting plate.

[0017] When the user wants to keep the plastic pipe in a horizontal state during hot melting, the user first places the bottom surface of the support plate of the detachable support frame on the flat ground, and then puts the inner wall of the mounting ring installed on the top of the support rod onto the connecting plate. Since the inner diameter of the mounting ring is the same shape and size as the outer diameter of the connecting plate, the mounting ring can be fixed on the connecting plate. At this time, the user can ensure that the plastic pipe can always be kept in a horizontal state during the entire thermoplastic process, avoiding uneven heating of the inner or outer wall of the plastic pipe and resulting in loose welding. At the same time, if thermoplastic work is performed in a narrow place, the user can also remove the mounting ring from the connecting plate to ensure that the user can continue thermoplastic welding work in a narrow environment.

[0018] The beneficial effects brought by the present invention are:

[0019] 1. By arranging the fastening component, heating component, temperature detection component, handle, and replaceable thermoplastic component, the user can select different replaceable thermoplastic components according to the different sizes of plastic pipes when thermoplastic welding two plastic pipes of the same model, and then select the inner wall thermoplastic component and the outer wall thermoplastic component that match the inner diameter and outer diameter of the plastic pipes of different models, thereby solving the technical problem of how to weld plastic pipes of different models.

[0020] 2. Through the arrangement and coordination of the cylindrical handle, button, working indicator light, current amplification module, heating plate, power cord, temperature detector, temperature detection line, and reading screen, when the user uses the welding machine, after the current amplification module is powered on through the power cord, the button can accurately control the working state and the stop state of the current amplification module. When the current amplification module heats the heating plate, the temperature detection line can transmit the temperature of the heating plate to the temperature detector, and the temperature detector transmits the temperature data to the reading screen, which can facilitate the user to check the heating temperature and judge whether the heating plate has reached the temperature suitable for thermoplasticizing the plastic pipe. By connecting the working indicator light to the current amplification module, when the current amplification module starts working, the working indicator light will light up, thereby reminding the user that the current amplification module is in the heating working state, thereby preventing the user from being burned by accidental touch.

[0021] 3. The setting of the detachable support frame allows the user to place the support plate on a flat bottom surface when thermoforming the plastic pipe, and then install the mounting ring on the support rod on the connecting plate. At this time, the entire device can be in a fixed state, and the thermoformed plastic pipe can be in a horizontal state to avoid uneven heating and poor welding. At the same time, the entire device structure is compact and simple, which is convenient for users to carry with them, and thermoplastic welding work can also be performed in narrow working scenes.

One end of the power cord 503 is electrically connected to the current amplification module 501 through the line inlet, and the other end of the power cord 503 is electrically connected to the power source.

[0039] When the user starts to heat the pipe, the user first inserts the other end of the power cord 503 into the matching power interface to power the current amplifying module 501. When the current amplifying module 501 is powered, the user presses the button 103 on the handle, and the current amplifying module 501 starts to amplify the current. At the same time, the working indicator light 104 connected to the current amplifying module 501 lights up to indicate that the current amplifying module 501 has started current amplification. The heating plate 502 connected to the current amplifying module 501 starts current amplification. During operation, the heating plate 502 will continuously heat the cake 301 of the replaceable thermoplastic component under the flow of large current. At the same time, the temperature detection line connected to the heating plate 502 will collect the temperature of the heating plate 502, and then transmit the temperature data to the temperature detector 402, and then to the reading screen 401. The current amplification function of the current amplification module 501 can heat the cake 301 through the heating plate 502, so that the thermoplastic components on the outer wall of the pipe and the thermoplastic components on the inner wall of the pipe can quickly reach the thermoplastic temperature of the plastic pipe.

[0040] It also includes a detachable support frame, which is set on the ground and connected to the connecting plate 102 at the top. The detachable support frame includes: a support plate 601, a support rod 602, and a mounting ring 603. The support plate 601 is set horizontally on the ground. The axis of the support rod 602 is perpendicular to the support plate 601. The support rod 602 is set on the middle top surface of the support plate 601, and the lower end of the support rod 602 is fixedly connected to the support plate 601. The mounting ring 603 is an iron tube body. The mounting ring 603 has the same shape as the connecting plate 102. The inner diameter of the mounting ring 603 matches the outer diameter of the connecting plate 102. The mounting ring 603 is set at the top of the support rod 602. The mounting ring 603 is fixedly connected to the support rod 602 and is sleeved on the outside of the connecting plate 102.

[0041] When the user wants to keep the plastic pipe in a horizontal state during hot melting, the user first places the bottom surface of the support plate 601 of the detachable support frame on a flat ground, and then puts the inner wall of the mounting ring 603 installed on the top of the support rod 602 onto the connecting plate 102. Since the inner diameter of the mounting ring 603 is the same shape and size as the outer diameter of the connecting plate 102, the mounting ring 603 can be fixed on the connecting plate 102. At this time, the user can ensure that the plastic pipe can always be kept in a horizontal state during the entire thermoplastic process, avoiding uneven heating of the inner or outer wall of the plastic pipe and resulting in loose welding. At the same time, if thermoplastic work is performed in a narrow place, the user can also remove the mounting ring 603 from the connecting plate 102 to ensure that the user can continue thermoplastic welding work in a narrow environment.

[0042] Working principle:

[0043] When the user wants to weld two plastic pipes of the same signal, the user first places the bottom surface of the support plate 601 of the detachable support frame on the flat ground, and then inserts the inner wall of the mounting ring 603 installed on the support rod 602 into the outer wall of the connecting plate 102. Since the inner diameter of the mounting ring 603 is the same shape and size as the outer diameter of the connecting plate 102, the mounting ring 603 can be fixed on the connecting plate 102. Then, the replaceable thermoplastic component is installed. First, the two locking bolts are respectively inserted into the two threaded through holes of the two locking ear blocks set on both sides of the second fastening block 202, and then the semicircular groove of the second fastening block 202 is set to fit together with the semicircular groove of the first fastening block 201. The two semicircular grooves 203 are arranged to form a circle, and then the cake block 301 is placed in the circle. Then, the two locking bolts are respectively passed through the two threaded through holes of the two locking ear blocks arranged on both sides of the first fastening block 201. Then, the two locking bolts are rotated to tightly connect the first fastening block 201 and the second fastening block 202. At the same time, the cake block 301 arranged in the circle formed by the two semicircular grooves 203 can be squeezed and fixed. Then, the heating component is started to heat the replaceable thermoplastic component. The user first inserts the other end of the power cord 503 into the matching power interface to power the current amplifying module 501. When the current amplifying module 501 is powered, the user presses the button 103 on the handle, and the current amplifying module 501 starts to heat. The working indicator light 104 connected to the current amplifying module 501 lights up to indicate that the current amplifying module 501 has started heating. When the current amplifying module 501 starts working, the current amplified by the current amplifying module 501 continuously passes through the heating plate 502 to heat the cake 301 of the replaceable thermoplastic component. At the same time, the heat of the cake 301 is also transferred to the thermoplastic block 302 on the inner wall of the plastic pipe and the thermoplastic block 303 on the outer wall of the plastic pipe. At the same time, when the current amplifying module 501 starts heating the heating plate 502, the temperature detection line detects the heat emitted by the heating plate 502 and transmits the collected heat data to the temperature detector 402. The temperature detector 402 converts the collected data into digital data and transmits it to the reading screen 401. At this time, the reading screen 401 will display the current heating temperature of the heating component, so that the user can accurately judge whether the temperature heated by the heating plate 502 has reached the level that can be used to heat-melt the plastic pipe. When the temperature displayed on the reading screen 401 reaches the temperature that can be used to heat-plasticize the plastic pipe, the user will hold one end of one of the plastic pipes tightly, insert the inner wall of the plastic pipe into the outer wall of the thermoplastic block 302 on the inner wall of the pipe, and squeeze it hard to prevent it from falling off. Then, pick up one end of the other plastic pipe, insert the outer wall of the plastic pipe into the thermoplastic block 303 on the outer wall of the pipe, and squeeze it hard. When the heat-melting of the two plastic pipes is completed,Pull out the two plastic pipes from the hot-melt blocks on the inner wall of the plastic pipe and the hot-melt blocks on the outer wall of the plastic pipe, then insert one end of the plastic pipe with the outer wall being hot-melted into the other end of the plastic pipe with the inner wall being hot-melted, and then apply manpower to keep squeezing for a period of time to complete the welding. After the welding is completed, check whether the weld is firm, loose, or deformed. If the above situation occurs, saw off the weld, then smooth the saw surface, and repeat the above hot-melt operation. During the hot-melt process, it is necessary to keep the hot-melt ends of the two plastic pipes in close contact with the plastic pipe outer wall thermoplastic block 303 and the plastic pipe inner wall thermoplastic block 302 to prevent uneven heating from causing loose welding.
