[0001] This utility model relates to the field of hot melt welding machine technology, and in particular to a portable hot melt welding machine for PE pipes. Background Technology

[0002] A hot melt welding machine is a device that uses the principle of hot melting for welding. It is mainly used for welding thermoplastic materials such as plastics and rubber. Among them, the portable hot melt welding machine for PE pipes is a device specifically designed for welding polyethylene pipes.

[0003] When using existing technology, the high temperatures generated during welding cannot be effectively isolated, increasing the risk of injury to operators. It may also cause external interference to the welding area, affecting the welding quality of the pipeline. Summary of the Invention

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of not having an effective protective isolation structure, which increases the safety risk for operators when welding and makes the welding quality susceptible to external interference. To this end, we propose a portable hot melt welding machine for PE pipes.

[0005] To achieve the above objectives, this application adopts the following technical solution: a portable PE pipe hot melt welding machine, comprising a base, a protective top cover rotatably connected to one end of one side of the base via a rotating shaft, a first rotating shaft installed at both ends of the top of the base, a lower clamp slidably connected to the surface of the first rotating shaft, an upper clamp slidably connected to the surface of the first rotating shaft, a bolt inserted into the inner wall of one end of the upper clamp, one end of the bolt being threadedly connected to the inner wall of the lower clamp, pin grooves being provided on both sides of one end of the protective top cover, an operating handle slidably connected to the surface of the first rotating shaft, clamping blocks rotatably connected to both sides of the operating handle via rotating shafts, one end of the clamping block being inserted into the inner wall of the pin groove, a hot melt device body installed at the bottom of the protective top cover, casters installed around the bottom of the base, two lifting cylinders installed on both sides of the base, and support feet installed at the output end of the lifting cylinders.

[0006] Preferably, a sliding groove is provided on one side of the protective top cover, and a first sliding buckle is slidably connected to the inner wall of the sliding groove, and the inner wall of the first sliding buckle is slidably connected to the surface of the clamping block.

[0007] Preferably, a slide rod is installed inside the slide groove, and one end of the slide rod passes through one side of the first slide buckle and is fixedly connected to one side of the inner wall of the slide groove.

[0008] Preferably, a spring is fixedly connected to one side of the first sliding buckle, and the other end of the spring is fixedly connected to one side of the inner wall of the slide groove.

[0009] Preferably, the protective top cover has mounting grooves at both ends, an exhaust fan is installed at the bottom of the mounting groove, a filter screen is installed at the top of the mounting groove, and a filter pad is installed inside the filter screen.

[0010] Preferably, the base has a guide groove inside, and both sides of the lower clamp are rotatably connected to auxiliary wheels via a rotating shaft. The surface of the auxiliary wheels is slidably connected to the inner wall of the guide groove.

[0011] Preferably, anti-slip pads are installed on the top of the lower clip and the bottom of the upper clip.

[0012] Technical effects and advantages of this utility model: In this invention, the user rotates the clamping block via the pivot, inserting one end of the clamping block into the inner wall of the pin groove, then releases the first sliding buckle, causing the spring to release and push the first sliding buckle back, preventing the clamping block from unfolding to the sides. After welding is completed, the user removes the protective top cover, unfolds it, and then moves the lower clamp along the first pivot, so that the pipe interfaces at both ends come into contact, making the molten surfaces of the two pipe sections fit tightly together.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0016] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a portable PE pipe hot melt welding machine, including a base 1, a protective top cover 2 rotatably connected to one end of the base 1 via a rotating shaft, a first rotating shaft 3 installed at both ends of the top of the base 1, a lower clamp 4 slidably connected to the surface of the first rotating shaft 3, an upper clamp 5 slidably connected to the surface of the first rotating shaft 3, a bolt 6 inserted into the inner wall of one end of the upper clamp 5, one end of the bolt 6 being threadedly connected to the inner wall of the lower clamp 4, pin grooves 7 being provided on both sides of one end of the protective top cover 2, an operating handle 8 slidably connected to the surface of the first rotating shaft 3, clamping blocks 9 rotatably connected to both sides of the operating handle 8 via rotating shafts, one end of the clamping blocks 9 being inserted into the inner wall of the pin groove 7, a hot melt device body 10 installed at the bottom of the protective top cover 2, casters 11 installed around the bottom of the base 1, two lifting cylinders 12 installed on both sides of the base 1, and support feet 13 installed at the output end of the lifting cylinders 12. A sliding groove 14 is provided on one side of the protective top cover 2. A first sliding buckle 15 is slidably connected to the inner wall of the sliding groove 14. The inner wall of the first sliding buckle 15 is slidably connected to the surface of the clamping block 9. A sliding rod 16 is installed inside the sliding groove 14. One end of the sliding rod 16 passes through one side of the first sliding buckle 15 and is fixedly connected to one side of the inner wall of the sliding groove 14. A spring 17 is fixedly connected to one side of the first sliding buckle 15. The other end of the spring 17 is fixedly connected to one side of the inner wall of the sliding groove 14. Both ends of the protective top cover 2 are provided with mounting grooves 18. An exhaust fan 19 is installed at the bottom of the mounting groove 18. A filter screen 20 is installed at the top of the mounting groove 18. A filter pad 21 is installed inside the filter screen 20. A guide groove 22 is provided inside the base 1. Auxiliary wheels 23 are rotatably connected to both sides of the lower clamp 4 through a rotating shaft. The surface of the auxiliary wheel 23 is slidably connected to the inner wall of the guide groove 22. Anti-slip pads 24 are installed at the top of the lower clamp 4 and the bottom of the upper clamp 5. Specifically: When the user is ready to use the equipment, the controller drives the lifting cylinder 12 to retract the support legs 13, causing the casters 11 at the bottom of the base 1 to contact the ground. The user then moves the equipment to the work location using the casters 11. Next, the user drives the lifting cylinder 12 to extend the support legs 13 downwards, lifting the equipment. The user then moves the first sliding buckle 15 along the inner wall of the slide groove 14 via the slide rod 16. The first sliding buckle 15 compresses the spring 17, causing it to retract. At this point, the first sliding buckle 15 releases its grip on both sides. The restriction of end clamp 9 allows the user to rotate the protective top cover 2 via the pivot on one side of the base 1, thus unfolding the protective top cover 2. At this time, the user can tighten bolt 6, causing the thread at one end of bolt 6 to disengage from the inner wall of the lower clamp 4, releasing the fixed position of the upper clamp 5 and the lower clamp 4. The user can then rotate the upper clamp 5 via the pivot, unfolding it. The lower clamp 4 can be moved along the inner wall of the guide groove 22 via the auxiliary wheel 23 to adjust its position according to the required pipe type. Once the PE pipe position is adjusted, the user can then... By rotating the pivot, the upper clamp 5 and lower clamp 4 are closed. Anti-slip pads 24 installed inside the upper and lower clamps 5 and 4 prevent the fixed pipe from shifting during welding. The user then closes the protective top cover 2 via the pivot and rotates the clamp 9 so that one end of the clamp 9 is inserted into the inner wall of the pin groove 7. The first sliding buckle 15 is then released, causing the spring 17 to release and push the first sliding buckle 15 back, thus restricting the clamps 9 at both ends and preventing them from unfolding to the sides. After welding is completed, the user... The user releases the protective top cover 2, unfolds it, and then moves the lower clamp 4 along the first rotating shaft 3 to bring the pipe interfaces at both ends into contact, so that the molten surfaces of the two pipe sections fit tightly together. Then, the user drives the exhaust fan 19 installed inside the mounting slot 18 through the controller to draw away the heat emitted by the heat fusion device body 10. The heat is then filtered through the filter pad 21 inside the filter screen 20 and discharged, accelerating the cooling efficiency of the heat fusion device body 10. Alternatively, the user can unfold the protective top cover 2 to the top of the upper clamp 5 to cool the welded pipe.

[0017] Working principle: When the user is ready to use the equipment, first, the user drives the lifting cylinder 12 via the controller to retract the support leg 13, so that the universal wheel 11 at the bottom of the base 1 contacts the ground. Then, the user uses the universal wheel 11 to move the equipment to the work site, and drives the lifting cylinder 12 to extend the support leg 13 downward, so that the support leg 13 supports the equipment. The user moves the first sliding buckle 15 along the inner wall of the slide groove 14 via the slide rod 16. The first sliding buckle 15 compresses the spring 17 to store force and retract, thereby releasing the restriction on the clamps 9 at both ends. The user can rotate the protective top cover 2 via the pivot on one side of the base 1 to unfold the protective top cover 2. The user tightens the bolt 6 to dislodge the thread at one end of the bolt 6 from the inner wall of the lower clamp 4, releasing the position fixation of the upper clamp 5 and the lower clamp 4, and then rotates the upper clamp 5 via the pivot to unfold it, so that the pipe to be processed can be opened. The user moves the lower clamp 4 along the inner wall of the guide groove 22 using the auxiliary wheel 23 to adjust the pipe position. Then, the user rotates the upper clamp 5 through the pivot to close it with the lower clamp 4. The anti-slip pads 24 on the inner sides of the upper clamp 5 and the lower clamp 4 are used to fix the pipe and prevent it from shifting during welding. After that, the user closes the protective top cover 2, rotates the clamp 9 so that one end of it is inserted into the inner wall of the pin groove 7, and then releases the first sliding buckle 15. The spring 17 is released and rebounds, pushing the first sliding buckle 15 to restrict the clamp 9 and prevent it from unfolding to both sides. The user releases the restriction of the protective top cover 2 and unfolds it. The user moves the lower clamp 4 along the first pivot 3 so that the pipe interfaces at both ends are in close contact and the molten surfaces are in contact. The exhaust fan 19 in the mounting groove 18 is driven by the controller to extract the heat emitted by the hot melt device body 10 and discharge it after being filtered by the filter pad 21 in the filter screen 20.

[0018] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
