Description

Technical Field

[0001] This utility model relates to the field of PE pipe technology, specifically a hot-melt device for connecting PE pipes. Background Technology

[0002] PE pipe, also known as polyethylene pipe, is a type of plastic pipe characterized by its corrosion resistance, impact resistance, and long service life. PE pipes have a wide range of applications, with water supply pipes and gas pipes being its two largest markets.

[0003] Chinese patent publication number CN214082886U discloses a "PE pipe fitting hot-melt tooling". When hot-melting two pipes together, the following steps are taken: remove the hexagonal bolts, then remove the upper semi-circular ring. Place the two pipes to be connected into the lower semi-circular rings on two pipe fitting devices, then fit the upper semi-circular ring onto the pipes. Tighten the hexagonal bolts to secure the two pipes together. After securing the pipes, activate the heating plate and the electric telescopic rod. The electric telescopic rod moves the heating plate downwards, causing the bottom of the heating plate to... Positioned on a T-shaped track, move the two pipe fitting devices inwards so that the pipe connections on the two fitting devices are tightly against the left and right sides of the heating plate. This allows the heating plate to heat-melt the pipe connections. After the heat-melting is complete, activate the electric telescopic rod, which moves the heating plate upwards and then inwards to move the two pipe fitting devices inwards again. This allows the pipes inside the two fitting devices to heat-melt and connect, achieving the effect of heat-melting the two pipes together. Then, turn on the fan to blow air downwards, cooling the pipe connections and ensuring the connection is quickly formed, thus guaranteeing the quality of the connection.

[0004] However, the upper and lower semicircular rings in the aforementioned patent can only position PE pipes of one size and cannot clamp and fix PE pipes of different sizes, which reduces the applicability of PE pipe clamping and is quite troublesome. Therefore, we propose a PE pipe connection hot melt device to solve the above-mentioned problems. Utility Model Content

[0027] Example 1

[0028] In one embodiment, such as Figures 1-4 As shown, a heat fusion device for connecting PE pipes includes:

[0029] Base plate 1;

[0030] Electric slide rail 2 is located in the middle of the upper surface of the base plate 1;

[0031] The slider 3 is provided in two sets and is slidably connected to both sides of the upper end of the electric slide rail 2;

[0032] The lower semicircular plate 4 is provided in two sets, and is respectively installed on the upper end surface of the two sets of sliders 3;

[0033] The upper semicircular plate 5 is provided in two sets, and is respectively positioned above the two sets of lower semicircular plates 4;

[0034] The positioning assembly is used to position the PE pipe between the lower semicircular plate 4 and the upper semicircular plate 5. Two sets are provided, which are respectively set on the two sets of upper semicircular plates 5. The positioning assembly includes a positioning plate 6, which is set below the upper semicircular plate 5. An adjusting component is provided between the upper semicircular plate 5 and the positioning plate 6.

[0035] The adjusting component includes a lifting block 7, which is connected to the upper surface of the positioning plate 6. The upper surface of the lifting block 7 slides through the upper semicircular plate 5 and extends to the upper end of the upper semicircular plate 5. A threaded rod 8 is threadedly connected to the upper end of the lifting block 7. A bracket 9 is rotatably connected to the upper end of the threaded rod 8. A rotary motor 10 is provided on the upper surface of the bracket 9. The output end of the rotary motor 10 passes through the bracket 9 and is connected to the threaded rod 8. A set of limiting blocks 11 is provided on both sides of the bracket 9. A set of limiting rods 12 is provided on the lower surface of both sets of limiting blocks 11. The lower ends of both sets of limiting rods 12 slide into the interior of the lifting block 7.

[0036] Specifically, the rotary motor 10 is started, which drives the threaded rod 8 to rotate. With the cooperation of the limit rod 12, the lifting block 7 moves downward, and the lifting block 7 drives the positioning plate 6 to move downward. The positioning plate 6 moves downward to fix the PE pipe inside the upper semicircular plate 5 and the lower semicircular plate 4. The electric slide rail 2 drives the two sets of sliders 3 to slide, thereby connecting the two sets of heat-fused PE pipes. By setting the positioning assembly consisting of the positioning plate 6 and the adjusting parts, the positioning plate 6 can move up and down to fix PE pipes of different sizes between the lower semicircular plate 4 and the upper semicircular plate 5, and then heat-fused them together. This improves the applicability of the heat-fusion device and avoids the problem that it can only position PE pipes of one size and cannot clamp and fix PE pipes of different sizes. It is quite practical.

[0037] like Figures 2-4As shown, a first fixing plate 13 is provided on the outer walls of both sides of the two sets of lower semicircular plates 4. Multiple slots 14 are provided on the upper surfaces of the two sets of first fixing plates 13.

The coordinated use of the first fixing plates 13, slots 14, second fixing plates 15, and locking blocks 16 improves the stability of the connection between the lower semicircular plates 4 and the upper semicircular plates 5, and facilitates the movement of the PE pipe. The lower surfaces of the two sets of brackets 9 are respectively connected to the upper surfaces of the multiple sets of second fixing plates 15. The second fixing plates 15 provide support for the brackets 9 and facilitate their movement.

[0038] like Figures 1-4 As shown, two sets of auxiliary blocks 17 are provided on the upper surface of each of the two sets of brackets 9. A set of sliding rods 18 are slidably passed through each set of auxiliary blocks 17. One end of each set of sliding rods 18 is connected to the two side walls of the adjusting block 19. A first hydraulic rod 20 is provided on the upper surface of the adjusting block 19. The upper end of the first hydraulic rod 20 is connected to the lower surface of the support plate 21. The lower surface of the support plate 21 is connected to the upper surface of the base plate 1. When the first hydraulic rod 20 is stretched, the first hydraulic rod 20 drives the adjusting block 19 to move downward. The adjusting block 19 drives the multiple sets of sliding rods 18 to move downward. The multiple sets of sliding rods 18 drive the auxiliary blocks 17 to move downward. The multiple sets of auxiliary blocks 17 drive the upper semicircular plate 5 to move downward through the brackets 9, thereby locking the two sets of upper semicircular plates 5 onto the upper ends of the two sets of lower semicircular plates 4, thus fixing the PE pipe between the lower semicircular plate 4 and the upper semicircular plate 5.

[0039] like Figures 2-3 As shown, a hot melt machine 22 is installed above the electric slide rail 2. A mounting plate 23 is connected to one side of the hot melt machine 22, and a connecting rod 24 is connected to one side of the mounting plate 23. A connecting plate 25 is installed at the other end of the connecting rod 24. A second hydraulic rod 26 is connected to the side wall of the connecting plate 25. The second hydraulic rod 26 is installed on one side wall of the support plate 21. A through hole 27 is opened on the support plate 21, and the connecting rod 24 passes through the through hole 27. When the hot melt machine 22 is started, it can perform a hot melt operation on one end of two sets of PE pipes. After the PE pipes are hot melted, the second hydraulic rod 26 is stretched. The second hydraulic rod 26 drives the connecting rod 24 to move through the connecting plate 25. The connecting rod 24 drives the hot melt machine 22 to move to one side through the mounting plate 23, which facilitates the subsequent connection of the two sets of hot melted PE pipes.

[0040] Example 2

[0041] In one embodiment, such as Figures 2-3As shown, a support ring 28 is slidably sleeved on the outer side of the connecting rod 24. A set of bent support plates 29 are provided on both sides of the outer wall of the support ring 28. The other ends of the two sets of bent support plates 29 are connected to the side wall of the support plate 21. By setting the support ring 28, the connecting rod 24 can be supported, thereby improving the stability of the movement of the connecting rod 24. By setting the bent support plates 29, the support ring 28 can be supported, thereby providing auxiliary support for the connecting rod 24.
