Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot melt welding technology, and in particular to a quick-alignment welding device for water supply pipes. Background Technology
[0002] Pipe melters are mainly used for heating, melting, and connecting thermoplastic pipes and molds. They work based on the principle of electrothermal heating and heat the plastic pipes to a molten state by precisely controlling the temperature and time to achieve seamless connection.
[0003] When using a pipe fusion welder, users need to install the corresponding heating die according to the required pipe specifications. After connecting the power, insert the pipe and fittings into the heating port of the welder. After they melt, quickly connect them together and maintain a certain pressure until they cool and solidify. When inserting one end of each pipe into the inner and outer sides of the corresponding heating die, the pipe end is prone to shifting. This shift will cause uneven contact area between the pipe and the die, resulting in some pipes not being fully heated, leading to a weak weld. At the same time, overheating may also damage the pipe material. In addition, some existing pipe fusion welders have a support at the bottom of the equipment to improve operational stability, allowing the pipe fusion welder to be placed on a platform or the ground during use. However, this type of support only provides support for the pipe fusion welder. After the operator inserts one end of the pipe into the heating die for fusion, the fused pipe adheres to the heating die, which can easily cause the pipe fusion welder to tip over or be dragged when the pipe is pulled out.

Two first guide covers 7 are fixedly installed on the outer side of the first hot melt die head 5, and two second guide covers 8 are fixedly installed on the outer side of the second hot melt die head 6. A support ring 9 is fixedly installed at the lower part of the control box 1. Two telescopic grooves 10 are opened in the support ring 9, and a telescopic rod 11 and a foot pedal 12 are movably installed in the telescopic grooves 10.
[0021] like Figures 1-2 As shown, a connecting block 13 is fixedly installed at one end of the telescopic rod 11, and a connecting groove 14 is opened at one end of the foot pedal 12. The connecting block 13 and the connecting groove 14 are axially connected to each other. The foot pedal 12 has an L-shaped structure. The support ring 9 allows the entire device to be placed stably on the operating table or the ground, which facilitates the operator to perform heat fusion operation on one end of the pipe. Two sets of telescopic rods 11 and foot pedals 12 are inserted into the support ring 9, and one end of the foot pedal 12 can rotate at one end of the telescopic rod 11, which facilitates the operator's foot to press the foot pedal 12 during operation, thereby further improving the operational stability of the entire device.
[0022] like Figure 1 , Figures 3-4As shown, two first guide covers 7 are respectively provided with first positioning grooves 15 on their outer sides. A first semi-circular positioning block 16 is fixedly installed on the outer side of the first positioning groove 15. Limiting rings 17 are respectively fixedly installed on the inner side of the two first guide covers 7. A guide slope is provided between the side of the limiting ring 17 opposite to the first hot melt die head 5 and the inner side of the first guide cover 7. A semi-circular fixing hoop 20 is inserted into the first positioning groove 15. A third positioning groove 21 is provided on the inner side of the semi-circular fixing hoop 20, and the third positioning groove 21 is snapped onto the outer side of the first semi-circular positioning block 16. The two first guide covers 7 are respectively inserted into the outer side of the first hot melt die head 5, and the two ends of the two semi-circular fixing hoop 20 are fixedly connected by bolts. The two first guide covers 7 are inserted into the outer side of the first hot melt die head 5, and the internal limiting rings 17 can guide one end of the pipe into the first hot melt die head 5. Inside, to ensure the quality of heat fusion at one end of the pipeline, the first guide cover 7 and the limiting ring 17 are made of ceramic, and the combination of the two first guide covers 7 is trumpet-shaped. The second guide cover 8 has a second positioning groove 18 on its outer side, and a second semi-circular positioning block 19 is fixedly installed on the outer side of the second positioning groove 18.

Then, one end of the two foot pedals 12 can be rotated at a certain angle on the corresponding connecting block 13 with the connecting groove 14 as the axis, so that the operator's foot can step on the foot pedals 12, thus completing the stability of the entire device during use.
[0024] Then, one end of each of the two pipe sections to be heat-melted is inserted into the two first guide covers 7 and the two second guide covers 8 respectively. The trumpet-shaped structure of the two first guide covers 7 and the two second guide covers 8 guides the movement of one end of the pipe. That is, after being guided by the two first guide covers 7 and the two second guide covers 8 respectively, one end of each pipe section is inserted into the inner side of the first heat-melting die head 5 and the outer side of the second heat-melting die head 6 at a uniform speed, thereby achieving precise heat melting of one end of each pipe section.
