DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] As Figures 1 to 6 shown, an embodiment of the utility model provides a double - head hot - melt connection device for high - pressure pipelines, including a bottom plate 1. A clamping mechanism 2 for clamping and limiting raw materials is installed at the upper end of the bottom plate 1. A support frame 3 is installed at the rear side of the upper surface of the bottom plate 1. A heating plate 4 is movably installed inside the support frame 3. A fixing rod 7 is installed inside the support frame 3, and the rod body of the fixing rod 7 movably penetrates through the inside of the heating plate 4. A positioning mechanism 5 for maintaining stability is installed between the heating plate 4 and the support frame 3. The heating plate 4 is located between the clamping mechanisms 2. A plurality of dies 6 are respectively installed on both sides of the heating plate 4, and each pair of dies 6 corresponds to each other and overlaps with each other.

[0024] As Figure 2 shown in Figure 4 another embodiment of the utility model, the clamping mechanism 2 includes fixing blocks 201. Moving blocks 205 are respectively and movably installed at both ends inside the fixing blocks 201. Lower clamping plates 206 are respectively installed at the upper ends of the moving blocks 205. Upper clamping plates 207 are respectively snap - fitted and installed at the upper ends of the lower clamping plates 206. A plurality of clamping holes 208 are formed between the upper clamping plates 207 and the lower clamping plates 206. Each clamping hole 208 corresponds to and overlaps with a die 6 respectively. An electric push rod 209 is installed at the rear end inside the lower clamping plate 206, and the output end of the electric push rod 209 is connected to the upper clamping plate 207. Guide rods 202 are respectively installed at both ends inside the fixing blocks 201, and the rod bodies of the guide rods 202 respectively movably penetrate through the inside of the moving blocks 205. A positive and negative lead screw 203 movably penetrates through the middle inside the fixing blocks 201, and the rod body of the positive and negative lead screw 203 respectively penetrates through the inside of the moving blocks 205 through threads. A motor 204 is installed on one side of the bottom plate 1, and the output end of the motor 204 is connected to the positive and negative lead screw 203.

[0025] When hot melt connection of raw materials is required, the electric push rod 209 will first push the upper clamping plate 207 upward to open the clamping hole 208. Then, the user selects the corresponding clamping hole 208 according to the diameter of the raw material and places the raw material. After the raw material is placed, the electric push rod 209 will pull the upper clamping plate 207 downward to make the upper clamping plate 207 cooperate with the clamping hole 208 to clamp and position the raw material. After the raw material is clamped, the user can heat the die head 6 through the heating plate 4. After the die head 6 is heated to the specified temperature, the motor 204 controls the moving blocks 205 to move relatively synchronously through the positive and negative lead screws 203, so that the moving blocks 205 respectively cooperate with the lower clamping plate 206 to drive the raw material to be inserted into the die head 6 for hot melt forming. After the raw material is hot melt formed, the motor 204 controls the moving blocks 205 to move in the reverse direction through the positive and negative lead screws 203, so that the moving blocks 205 drive the separation between the raw material and the die head 6 respectively. After the raw material is separated, the user pushes the heating plate 4 upward through the handle 504 to make it leave between the raw materials. Then, the motor 204 controls the moving blocks 205 to move relatively again through the positive and negative lead screws 203, so that the moving blocks 205 drive the raw material to be inserted and the connecting part is hot melt connected to complete the connection work of the pipeline.

[0026] As Figure 6 shown, in another embodiment of the present invention, the positioning mechanism 5 includes a movable groove 501 and a guiding groove 505. The movable groove 501 is arranged on one side of the inner rear end of the heating plate 4. A positioning rod 502 is movably installed through the inside of the movable groove 501. The guiding groove 505 is centered on the fixed rod 7 and is arranged on the inner wall of the support frame 3 and close to one side of the movable groove 501. One end of the positioning rod 502 is snap-fitted inside the movable groove 501. A first spring 503 is installed between the positioning rod 502 and the movable groove 501. A groove 506 is arranged on the upper end of the inside of the support frame 3 and close to one side of the guiding groove 505. One end of the positioning rod 502 is movably installed through the inside of the groove 506. A limiting block 508 is movably installed inside the groove 506. The limiting block 508 is in contact with the positioning rod 502. A clamping groove 509 is arranged on the side of the limiting block 508 close to the positioning rod 502. One end of the positioning rod 502 is snap-fitted inside the clamping groove 509. A second spring 507 is installed between the lower end of the limiting block 508 and the groove 506. A push rod 510 is movably installed through the upper end of the inside of the groove 506. The lower end of the push rod 510 is connected to the limiting block 508. A handle 504 is installed at the front end of the heating plate 4.

[0027] When hot melt connection of raw materials is required, the heating plate 4 remains horizontal with the fixed rod 7 as the axis, so that the heating plate 4 drives the die head 6 to be located between the clamping holes 208. At the same time, the positioning rod 502 will also be pushed by the first spring 503 and snap into the groove 506 and the engaging groove 509 to position the heating plate 4, ensuring that the heating plate 4 remains stable when driving the die head 6 to perform hot melt shaping on both ends of the raw materials. Then, after the raw materials and the die head 6 are separated, the user first pushes the push rod 510 to make the push rod 510 push the limit block 508 to move downward, so that the limit block 508 cooperates with the engaging groove 509 to push the positioning rod 502 out of the groove 506. Then, the user pulls the heating plate 4 upward through the handle 504, so that the heating plate 4 quickly disengages from between the raw materials. After the heating plate 4 moves upward, the raw materials can be quickly hot melt connected, improving the sealing performance between the raw materials and being more convenient.

[0028] The working principle of this high-pressure pipeline double-head hot melt connection device:

[0029] During use, first, when hot melt connection of raw materials is required, the electric push rod 209 will first push the upper clamping plate 207 to move upward to open the clamping hole 208. Then, the user selects the corresponding clamping hole 208 according to the diameter of the raw materials and places them. After the raw materials are placed, the electric push rod 209 will pull the upper clamping plate 207 to move downward, so that the upper clamping plate 207 cooperates with the clamping hole 208 to clamp and position the raw materials. After the raw materials are clamped, the user can heat the die head 6 through the heating plate 4. After the die head 6 is heated to the specified temperature, the motor 204 controls the moving blocks 205 to move relatively synchronously through the positive and negative lead screws 203, so that the moving blocks 205 respectively cooperate with the lower clamping plate 206 to drive the raw materials to be inserted into the die head 6 for hot melt forming. Then, after the raw materials are hot melt formed, the motor 204 controls the moving blocks 205 to move in the reverse direction through the positive and negative lead screws 203, so that the moving blocks 205 drive the separation between the raw materials and the die head 6 respectively. Then, after the raw materials and the die head 6 are separated, the user first pushes the push rod 510 to make the push rod 510 push the limit block 508 to move downward, so that the limit block 508 cooperates with the engaging groove 509 to push the positioning rod 502 out of the groove 506. Then, the user pulls the heating plate 4 upward through the handle 504, so that the heating plate 4 quickly disengages from between the raw materials. Then, the motor 204 controls the moving blocks 205 to move relatively again through the positive and negative lead screws 203, so that the moving blocks 205 drive the raw materials to be inserted and the connection parts are hot melt connected to complete the connection work of the pipeline.

[0030] Obviously, the above embodiments of the present utility model are merely examples for clearly illustrating the present utility model, rather than limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, based on the above description, other different forms of changes or variations can be made. It is impossible to list all the implementation manners here. Any obvious changes or variations derived from the technical solutions of the present utility model still fall within the protection scope of the present utility model.
