Technical Field
[0001] This utility model relates to the field of PE pipe splicing machines, and in particular to a PE pipe splicing machine. Background Technology
[0002] A PE pipe butt welding machine, also known as a PE pipe hot-melt butt welding machine or an electrofusion butt welding machine, is a specialized piece of equipment used to connect polyethylene (PE) pipes. This machine heats the ends of the PE pipes to melt them, then presses the two pipe sections together to form a strong connection. PE pipe butt welding machines are widely used in water supply, gas transmission, sewer systems, and agricultural irrigation.
[0003] Traditional PE pipe splicing machines require milling the pipe ends with a milling cutter, heating the pipe ends with a heating plate, and then performing heat fusion splicing. However, because the milling cutter and heating plate are placed independently, they need to be removed and installed, making the PE pipe splicing process inconvenient and requiring improvement. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PE pipe splicing machine that has the effect of convenient splicing and fixing.

[0016] In a preferred embodiment, the present invention can be further configured such that handles are provided at both ends of the mounting bracket.
[0017] In a preferred embodiment, the present invention can be further configured such that: the upper end of the support frame is horizontally slidably connected with a locking rod for inserting the slider.
[0018] In a preferred embodiment, the present invention can be further configured such that a spring located below the slider is provided inside the support frame.
[0019] In a preferred embodiment, the present invention can be further configured such that: a bidirectional lead screw is horizontally rotatably connected to the support base, the slide is threadedly connected to the bidirectional lead screw, and handwheels are provided at both ends of the bidirectional lead screw.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] like Figure 1 , Figure 2 As shown, a PE pipe splicing machine includes a support base 1, a pair of sliding rods 2, a pair of sliding blocks 3, a clamp 4, a pair of support frames 5, a milling cutter 6, and a heating plate 7.
[0028] like Figure 1 , Figure 2 As shown, the support base 1 is horizontally set on the ground, and a pair of sliding rods 2 are horizontally and side by side set on the upper end of the support base 1. A pair of slide blocks 3 are slidably connected to the sliding rods 2, and a clamp 4 is set on the slide blocks 3 and used to clamp the PE pipe. A double-acting screw 11 is horizontally rotatably connected to the support base 1, and the slide blocks 3 are threadedly connected to the double-acting screw 11. Handwheels 12 are set at both ends of the double-acting screw 11.
[0029] like Figure 1 , Figure 2 As shown, a pair of support frames 5 are vertically arranged on both sides of the middle position of the support base 1. A slider 51 is vertically slidably connected to the inner side of the support frame 5, and a spring 52 located below the slider 51 is provided inside the support frame 5 to buffer the slider 51 during the sliding process.
[0030] like Figure 1 , Figure 2 As shown, each slider 51 is horizontally provided with a rotating shaft 53, and the outer wall of the rotating shaft 53 is provided with a guide block 54. The inner side of the support frame 5 is provided with a guide clamp 55 for the guide block 54 to slide and embed. The guide block 54 is elongated and is used to cross the guide clamp 55 after flipping. At the same time, the upper end of the support frame 5 is horizontally slidably connected with a locking rod 56 for inserting the slider 51.
[0031] like Figure 1 , Figure 2 As shown, a rectangular mounting bracket 8 is provided between a pair of rotating shafts 53, a milling cutter 6 is provided at one end of the mounting bracket 8, and a heating plate 7 is provided at the other end of the mounting bracket 8.
[0032] like Figure 1 , Figure 2 As shown, both ends of the mounting bracket 8 are provided with slots 81 for the sliding rod 2 to be inserted, so as to limit and fix the mounting bracket 8. Both ends of the mounting bracket 8 are provided with handles 82 for easy lifting and control of the mounting bracket 8.
[0033] When it is necessary to connect PE pipes, first control the handwheel 12 to drive the double-acting screw 11 to rotate, and control the pair of slides 3 to move away from each other. Then place the PE pipes on the slides 3 and fix them with clamps 4, so that the axial direction of the pair of PE pipes is aligned.
[0034] Then, pulling the handle 82 causes the mounting bracket 8 to slide upwards. The mounting bracket 8 drives the rotating shaft 53 and the slider 51 to move upwards synchronously. At this time, the guide block 54 on the rotating shaft 53 slides within the guide clamp 55 on the support frame 5. After the guide block 54 slides to the outside of the guide clamp 55, the mounting bracket 8 can be controlled to rotate so that the end with the milling cutter 6 faces downwards.
[0035] Then, the mounting bracket 8 is controlled to move downwards, causing the guide block 54 to embed into the guide clamp 55. Under the combined action of the guide block 54 and the guide clamp 55, the mounting bracket 8 slides vertically. This continues until the slot 81 at the lower end of the mounting bracket 8 engages with the sliding rod 2, thus achieving the limiting and fixing of the mounting bracket 8. Subsequently, a pair of sliding blocks 3 can be controlled to move closer together, achieving the cutting and milling of the PE pipe end. Then, using the same working principle, the end of the mounting bracket 8 with the heating plate 7 is positioned downwards to achieve the heating and heat-melting of the PE pipe end.
[0036] Finally, control the mounting bracket 8 to move upward again, then control the mounting bracket 8 to rotate to a horizontal position, so that the guide block 54 crossbeams on the guide clamp 55, achieving the suspension and fixation of the mounting bracket 8. Then, insert the locking rod 56 into the slider 51 to achieve secondary fixation and increase stability. Finally, control the pair of slide blocks 3 to move closer to each other to achieve the docking and fixation of the PE pipe end position.
[0037] Therefore, by setting up a vertically sliding mounting bracket 8 and fixing the milling cutter 6 and the heating plate 7 on the mounting bracket 8, the rotation of the mounting bracket 8 can be controlled, enabling the rapid switching and operation of the milling cutter 6 and the heating plate 7, making the PE pipe connection process easier and more convenient, and improving construction efficiency.
[0038] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
