Description

Technical Field

[0001] This utility model relates to the field of pipe welding technology, and in particular to a PE pipe alignment welding device. Background Technology

[0002] Before connecting PE pipes, sufficient preparation work should be done, including the tools required for heat fusion. Before heat fusion connection, the material of the PE pipes, fittings, and tools should be inspected. Key inspection items include pressure rating, production date, consistency of raw materials, absence of visual damage, and whether the ends of the PE water supply pipes meet roundness standards. Appropriate specialized tools should be used according to different connection methods. PE pipes and fittings should not be heated with open flames. PE water supply pipes using fusion welding connections should use the same grade of materials and fittings. PE pipes with similar performance must pass a fusion welding test.

[0003] In the existing technology, when welding PE pipes, it is usually necessary to grind the pipes flat. However, the grinding machine, heating mechanism and alignment clamping equipment are usually separate, which makes the operation more cumbersome. In addition, grinding and heating will generate debris and odors, which will pollute the surrounding working environment. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a PE pipe alignment and welding device.

[0005] The technical solution of this utility model is a PE pipe alignment and welding device, comprising:

[0006] frame;

[0007] The protective mechanism includes a bottom shell and a transparent glass cover. The bottom shell is located in the middle of the frame and has openings at both the top and bottom. The transparent glass cover is rotatably connected to the bottom shell. Both ends of the bottom shell and the transparent glass cover have semi-circular notches.

[0008] The grinding mechanism is located inside the protective mechanism, and a second electric push rod for driving the grinding mechanism to move is installed inside the bottom shell.

[0009] The heating plate is located inside the protective mechanism, and a third electric push rod for driving the movement of the heating plate is installed inside the bottom shell.

[0010] The dust collection and purification mechanism is installed at the bottom of the frame;

[0011] Multiple clamping assemblies are provided, with no fewer than two sets of clamping assemblies on each side of the protective mechanism. Each clamping assembly includes a sliding seat, a lower arc plate on the sliding seat, and an upper arc plate rotatably connected to the lower arc plate. A locking buckle connects the lower arc plate and the upper arc plate. Guide slide rods are provided on both sides of the bottom shell, and multiple sliding seats are slidably mounted on the guide slide rods on the corresponding sides.

[0012] Preferably, the dust collection and purification mechanism includes a vacuum cleaner, a funnel, a storage box, an exhaust bend, and an air filter. The storage box and the vacuum cleaner are both installed at the bottom of the frame. The bottom of the bottom shell is connected to the funnel. The input end of the vacuum cleaner is connected to the funnel by a suction pipe. The output end of the vacuum cleaner is connected to the storage box by a discharge pipe. The exhaust bend is connected to the top of the inside of the storage box. The air filter is installed on the exhaust bend.

[0013] Preferably, the grinding mechanism includes a first movable bracket, a drive shaft rotatably mounted on the first movable bracket, two grinding discs respectively mounted at both ends of the drive shaft, and a power component for driving the drive shaft to rotate, wherein the first movable bracket is connected to the output shaft of the second electric push rod.

[0014] Preferably, the power assembly includes a servo motor, a first pulley, a second pulley, and a belt. The servo motor is mounted on a first movable bracket, and the second pulley and the first pulley are respectively mounted on the drive shaft and the output shaft of the servo motor. The second pulley and the first pulley are connected by belt drive.

[0015] Preferably, a first electric push rod is installed at both ends of the bottom shell, and the output ends of the two first electric push rods are respectively connected to a clamping assembly adjacent to one side of them.

[0016] Preferably, anti-slip pads are installed on the inner surfaces of both the lower and upper arc-shaped plates.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] 1. In this technical solution, the grinding mechanism and heating plate are integrated and installed on the equipment, which simplifies the equipment, eliminates the need for frequent manual equipment switching, and improves work efficiency.

[0019] 2. The protective mechanism prevents debris from flying out during the grinding process and reduces the emission of odors during hot melting, thus avoiding pollution to the surrounding working environment.

[0020] 3. By making the protective mechanism and clamping components detachable, the pipe can be unloaded during the up-and-down movement, thus eliminating the need to drive the pipe along its length to the end for removal. This prevents the pipe from being unable to unload due to limited indoor space. Attached Figure Description

[0025] Example 1

[0026] like Figures 1-4 As shown in the figure, the PE pipe alignment and welding device proposed in this embodiment includes a frame 1, a heating plate 16, a protective mechanism, a grinding mechanism, a dust collection and purification mechanism, and multiple sets of clamping components.

[0027] The protective mechanism includes a bottom shell 2 and a transparent glass cover 3. The bottom shell 2 is located in the middle of the frame 1. Both the upper and lower ends of the bottom shell 2 are open. The transparent glass cover 3 is rotatably connected to the bottom shell 2. Both ends of the bottom shell 2 and the transparent glass cover 3 are provided with semi-circular notches 10. The dust collection and purification mechanism is installed at the bottom of the frame 1.

[0028] The grinding mechanism is located inside the protective mechanism. A second electric push rod for driving the grinding mechanism to move is installed inside the bottom shell 2. The grinding mechanism includes a first movable bracket 18, a transmission shaft 171 rotatably mounted on the first movable bracket 18, two grinding discs 17 respectively mounted on both ends of the transmission shaft 171, and a power component for driving the transmission shaft 171 to rotate. The power component includes a servo motor 19, a first pulley 20, a second pulley 21, and a belt 22. The servo motor 19 is mounted on the first movable bracket 18. The second pulley 21 and the first pulley 20 are respectively mounted on the output shaft of the transmission shaft 171 and the output shaft of the servo motor 19. The second pulley 21 and the first pulley 20 are connected by the belt 22. The first movable bracket 18 is connected to the output shaft of the second electric push rod.

[0029] The heating plate 16 is located inside the protective mechanism, and a third electric push rod for driving the heating plate 16 to move is installed inside the bottom shell 2.

[0030] The clamping components on both sides of the protective mechanism are provided with no less than two sets. The clamping components include a sliding seat 6, a lower arc plate 4 provided on the sliding seat 6, and an upper arc plate 5 rotatably connected to the lower arc plate 4. Anti-slip pads 9 are installed on the inner surfaces of the lower arc plate 4 and the upper arc plate 5. Locking buckles 11 are connected between the lower arc plate 4 and the upper arc plate 5. Guide slide rods 7 are provided on both sides of the bottom shell 2. Multiple sliding seats 6 are slidably installed on the guide slide rods 7 on the corresponding sides. First electric push rods 23 are installed at both ends of the bottom shell 2. The output ends of the two first electric push rods 23 are respectively connected to the clamping components on the adjacent side.

[0031] Specifically, when aligning and welding two PE pipes, the two PE pipes are placed on both sides of the protective mechanism. Before placing the PE pipes, it is necessary to ensure that the multiple upper arc plates 5 are in the open rotating state. The PE pipes are placed on the corresponding multiple lower arc plates 4, and then the corresponding multiple upper arc plates 5 are rotated. The upper arc plates 5 and the lower arc plates 4 are connected and fixed by the locking buckle 11, thereby achieving effective fixation of the PE pipes.

[0032] The second electric push rod drives the grinding mechanism to move between the two PE pipes, so that the PE pipes come into contact with the grinding discs 17 on both sides. The power component drives the two grinding discs 17 to rotate synchronously, thereby achieving synchronous grinding of the ends of the PE pipes on both sides, making the ends of the PE pipes flatter and improving the welding effect of the PE pipes.

[0033] The grinding mechanism is reset, and the heating plate 16 is moved between the two PE pipes by the third electric push rod. The heating plate 16 is an electric heating plate, so that the PE pipes on both sides are in contact with the heating plate 16, thereby heating the ports of the heating plate 16 on both sides and melting the ports.

[0034] Finally, drive the heating plate 16 to reset, push the two PE tubes closer together, and make the two PE tubes stick together.

[0035] After the bonding of the PE pipes is completed and the pipe joints have cooled sufficiently, the transparent glass cover 3 and multiple upper arc plates 5 are rotated and opened, allowing the two bonded PE pipes to be removed. By setting the protective mechanism and clamping components to be detachable, the pipes can be unloaded during vertical movement, eliminating the need to drive the pipes along their length to the end for removal. This prevents the pipes from being unable to be unloaded due to limited indoor space.

[0036] Example 2

[0037] like Figure 2As shown, this embodiment proposes a PE pipe alignment and welding device. Compared with the first embodiment, in this embodiment, the dust collection and purification mechanism includes a vacuum cleaner 12, a funnel 13, a storage box 8, an exhaust bend 14, and an air filter 15. The storage box 8 and the vacuum cleaner 12 are both installed at the bottom of the frame 1. The bottom of the bottom shell 2 is connected to the funnel 13. The input end of the vacuum cleaner 12 is connected to the funnel 13 by a suction pipe. The output end of the vacuum cleaner 12 is connected to the storage box 8 by a discharge pipe. The exhaust bend 14 is connected to the top of the inside of the storage box 8. The air filter 15 is installed on the exhaust bend 14.

[0038] In this embodiment, the dust generated during the grinding process and the odor generated after heating are absorbed by the dust suction mechanism. The storage box 8 is used to store the absorbed waste, while the air filter 15 is used to filter the odor, thereby reducing air pollution.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
