Description

Technical Field

[0001] This utility model relates to the technical field of hot-melt connection devices, specifically a hot-melt connection device for PPR pipes. Background Technology

[0002] PPR pipes are a type of pipe made from PPR raw materials. PPR pipes have advantages such as energy and material saving, environmental friendliness, lightweight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. During the processing of PPR pipes, heat fusion connection is often required.

[0003] Currently, when heat-fusion connecting PPR pipes, the connection ends are typically melted manually using a heat fusion machine, and then the two molten PPR pipes are manually joined together. Manual operation makes it difficult to precisely control the force, resulting in uneven stress on the pipes during the connection process. This uneven stress leads to inconsistent distribution of the heat-fused material at the pipe joint, with some areas being too thin and others too thick, severely affecting the sealing and strength of the connection. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a PPR pipe hot-melt connection device, which solves the problem of uneven stress during traditional pipe connections.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PPR pipe hot-melt connection device, including a processing table, an installation groove on the processing table, and support members slidably installed on both sides of the installation groove. The support members are used to support the pipe, and the pipe is placed on top of the support members. Each support member is provided with a connecting block. A bidirectional screw is rotatably installed on the processing table, and the two sides of the screw are threadedly connected to the connecting blocks on both sides. Rotating the screw can drive the support members on both sides and the pipe placed on the support members to move closer or further away from each other synchronously.

[0008] Furthermore, a mounting block is provided on the processing table, and the lead screw is rotatably connected to the mounting block.

[0009] Furthermore, the lead screw is provided with a screwing component for rotating the lead screw.

[0010] Furthermore, the inner wall of the support member is provided with an anti-slip pad.

[0011] Furthermore, the processing table is provided with a through groove for the connecting block to pass through.

[0012] Furthermore, the mounting groove has a downwardly recessed groove in the middle.

[0013] Furthermore, a support block is provided at the bottom of the processing table.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a PPR pipe hot-melt connection device, which has the following advantages:

[0016] This PPR pipe hot-melt connection device features an installation groove on a processing table. Supports are slidably installed on both sides of the groove to hold the pipe. The pipe is placed on top of the support, and a bidirectional screw threaded to the connecting block of the support is rotated on the processing table. Rotating the screw precisely drives the support and the pipe to move closer or further apart synchronously. Compared to manual operation, the force control during pipe connection is more stable and uniform, improving the sealing and firmness of the pipe connection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3This utility model discloses a PPR pipe hot-melt connection device, including a processing table 1, a support block 10 at the bottom of the processing table 1, an installation groove 2 on the processing table 1, a recessed groove 11 in the middle of the installation groove 2 to prevent contact with the pipe, and support members 3 slidably installed on both sides of the installation groove 2. The inside of the support member 3 is arc-shaped, or it can be cylindrical. The support member 3 is used to support the pipe. An anti-slip pad 8 is provided on the inner wall of the support member 3. When the pipe is placed inside the support member 3, the weight of the pipe presses down on the anti-slip pad 8, and the anti-slip pad 8 prevents the pipe from slipping.

[0023] The pipe is placed on top of the support 3. Each support 3 is equipped with a connecting block 4. The processing table 1 has a through groove 9 for the connecting block 4 to pass through. A bidirectional lead screw 6 is rotatably installed on the processing table 1. An installation block 5 is provided on the processing table 1. The lead screw 6 is rotatably connected to the installation block 5. The two sides of the lead screw 6 are threadedly connected to the two connecting blocks 4 on both sides respectively. The lead screw 6 is equipped with a screwing part 7 for rotating the lead screw 6. Rotating the lead screw 6 can drive the two support 3 and the pipe placed on the support 3 to move closer or further away from each other synchronously.

[0024] In summary, this PPR pipe heat fusion connection device, during use, places two sections of PPR pipe to be connected within the support members 3 on both sides. The downward pressure of the pipes ensures full contact between the pipes and the anti-slip pads 8 on the support members 3. The anti-slip pads 8 effectively prevent the pipes from sliding during processing, ensuring stable pipe positioning. After the pipes are properly placed, a professional heat fusion tool is used to heat fused the two ends of the pipes. After the heat fusion is complete, immediately turn the knob. Turning this knob drives the support members 3 on both sides to move synchronously, causing the pipes to slowly connect. During the connection process, the pipes are subjected to uniform force, effectively avoiding connection problems caused by uneven force, thereby improving the connection effect.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
