[0001] This utility model relates to the field of pipe hot melt welding technology, and in particular to a pipe hot melt welding machine. Background Technology

[0002] In the construction of communication infrastructure, communication pipes play an important role in protecting core transmission media such as optical cables and electrical cables. As one of the mainstream connection methods for communication pipes, thermofusion connection is widely used in underground pipe networks, overhead lines and indoor wiring. Thermofusion welding machines are required when thermofusion connecting pipes.

[0003] Existing hot melt welding machines have shortcomings in terms of rapid and accurate positioning and connection, connection strength, and operational safety during hot melt welding, and their practicality needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a pipe hot melt welding machine that can quickly and accurately position the pipe, has strong hot melt welding stability, and does not require close contact with high-temperature components during the entire operation, thus ensuring high safety and practicality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pipe hot melt welding machine includes a base. Two first tracks are fixedly installed on the upper surface of the base. A clamping seat is slidably installed at each end of the first track. A column is fixedly connected at the middle position of the upper surface of the base. Two second tracks are fixedly installed on the side surface of the column. A heating seat is slidably installed on the outside of the second tracks. The heating seat is located between the two clamping seats. A threaded hole is provided on each of the symmetrical end faces of the clamping seat. A clamping screw is installed through the threaded hole. A clamping plate is rotatably installed on one end of the clamping screw. The clamping plate is located inside the clamping seat, and the lower edge of the clamping plate is in contact with the inner bottom end face of the clamping seat.

[0007] By adopting the above technical solution, pipes and joints can be quickly positioned and connected during hot melt welding. A stable connection force can be provided during welding, improving welding efficiency. At the same time, workers will not be close to high-temperature components, ensuring high operational safety.

[0008] Furthermore, a first resistance heating tube and a second resistance heating tube are fixedly installed on the outer surfaces of the symmetrical sides of the heating base, respectively. A first hot melt tube and a second hot melt tube are respectively installed on the outer surfaces of the symmetrical sides of the heating base by bolts. The first resistance heating tube is located inside the first hot melt tube, and the second resistance heating tube is sleeved on the outside of the second hot melt tube.

[0009] By adopting the above technical solution, the first and second hot-melt tubes can be flexibly replaced, ensuring that hot-melt operations can be performed on pipes and joints of different sizes.

[0010] Furthermore, a second lead screw is rotatably mounted at the end of the column. The second lead screw passes through a threaded hole on the outer surface of the heating seat, and the heating seat is threadedly connected to the second lead screw. A crank handle is mounted on the upper end of the second lead screw.

[0011] By adopting the above technical solution, the rotation of the second lead screw can be used to drive the heating seat to move in position.

[0012] Furthermore, a bearing seat is fixedly installed at each end of the base, and a first lead screw is rotatably installed between the two bearing seats. The two ends of the first lead screw pass through threaded holes on the side surface of the clamping seat.

[0013] By adopting the above technical solution, the rotation of the first lead screw can be used to drive the clamping seat to move.

[0014] Furthermore, the outer surface of the first lead screw is provided with two types of thread teeth with opposite thread directions, and the middle position of the first lead screw is used as the dividing point. A rotating shaft is rotatably installed at the end of the base. A synchronous pulley is sleeved on the outside of the rotating shaft and the first lead screw respectively. A synchronous belt is sleeved on the outside of the two synchronous pulleys. A handle is installed at one end of the rotating shaft.

[0015] By adopting the above technical solution, the rotating shaft can be rotated, and under the transmission of the synchronous pulley and the synchronous belt, the first lead screw can be driven to rotate. Since the first lead screw is provided with two threads with opposite directions, the rotation of the first lead screw can make the two clamping seats move closer or further apart.

[0016] Furthermore, a support rod is fixedly connected to the lower surface of the base, and a omnidirectional ball is fixedly connected to the lower end of the support rod.

[0017] By adopting the above technical solution, flexible position changes can be made.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model allows for the clamping and mounting of pipes and fittings onto two clamping seats during hot-melt welding. Then, rotating the first lead screw causes the pipes and fittings on the two clamping seats to engage with the second and first hot-melt pipes, respectively. Next, activating the first and second resistance heating tubes raises their temperatures, enabling the hot-melt operation of the pipes and fittings. Reversing the first lead screw causes the two clamping seats to move in opposite directions, separating the pipes and fittings from the second and first hot-melt pipes. Rotating the second lead screw raises the heating seat, and then rotating the first lead screw again brings the two clamping seats closer together, allowing the pipes and fittings to be connected. This ensures a stable connection force, guaranteeing a secure connection. The entire hot-melt welding process enables rapid positioning and connection, and workers are not in close contact with high-temperature components, resulting in high safety and high efficiency.

[0020] 2. This utility model allows for the selection of a first and second hot-melt pipe of corresponding size when hot-melt welding pipes, based on the required pipe size. The hot-melt components can be flexibly disassembled and assembled, making it highly practical. Attached Figure Description

[0024] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Reference Figure 1 , Figure 2A pipe hot melt welding machine includes a base 1. Two first tracks 2 are fixedly installed on the upper surface of the base 1. A clamping seat 3 is slidably installed at each end of the first track 2. A column 7 is fixedly connected to the middle position of the upper surface of the base 1. Two second tracks 8 are fixedly installed on the side surface of the column 7. A heating seat 10 is slidably installed on the outside of the second track 8. The heating seat 10 is located between the two clamping seats 3. A threaded hole is provided on each of the symmetrical end faces of the clamping seat 3, and a clamping screw 5 is installed through the threaded hole. A clamping plate 4 is rotatably installed on one end of the clamping screw 5. The clamping plate 4 is located inside the clamping seat 3, and the lower edge of the clamping plate 4 is in contact with the inner bottom end face of the clamping seat 3. A clamping seat 3 is fixedly installed at each end of the base 1. A bearing housing is provided, and a first lead screw 6 is rotatably mounted between two bearing housings. The two ends of the first lead screw 6 pass through threaded holes on the side surface of the clamping seat 3. Two types of threads with opposite directions are provided on the outer surface of the first lead screw 6, with the middle position of the first lead screw 6 as the dividing point. A second lead screw 9 is rotatably mounted on the end of the column 7. The second lead screw 9 passes through a threaded hole on the outer surface of the heating seat 10, and the heating seat 10 is threadedly connected to the second lead screw 9. A crank handle is mounted on the upper end of the second lead screw 9. A first resistance heating tube 12 and a second resistance heating tube 18 are fixedly mounted on the symmetrical outer surfaces of the heating seat 10, respectively. A first hot melt tube 11 and a second hot melt tube 19 are bolted to the symmetrical outer surfaces of the heating seat 10, respectively. The resistance heating tube 12 is located inside the first hot melt tube 11, and the second resistance heating tube 18 is sleeved on the outside of the second hot melt tube 19. During hot melt welding, the pipe and connector can be clamped and mounted on two clamping seats 3 respectively. Then, the first lead screw 6 is rotated, causing the pipe and connector on the two clamping seats 3 to engage with the second hot melt tube 19 and the first hot melt tube 11 respectively. Next, the first resistance heating tube 12 and the second resistance heating tube 18 are activated to increase the temperature of the first hot melt tube 11 and the second hot melt tube 19, thereby enabling the hot melt operation of the pipe and connector. Then, the first lead screw 6 is reversed, causing the two clamping seats 3 to move in opposite directions, thereby separating the pipe and connector. Do not separate the second hot melt tube 19 and the first hot melt tube 11. Then rotate the second screw 9 to raise the height of the heating seat 10. Then rotate the first screw 6 to bring the two clamping seats 3 closer together, so that the pipe and the joint are connected. At the same time, the pipe and the joint can always maintain a stable connection force, ensuring that the pipe and the joint can be firmly connected. In the entire hot melt welding process, rapid positioning and connection can be achieved. At the same time, the workers will not come into close contact with high-temperature components during the process, which is safe and efficient. In addition, when hot melt welding pipes, the first hot melt tube 11 and the second hot melt tube 19 of the corresponding size can be selected according to the size of the pipe to be welded. The hot melt components can be flexibly disassembled and assembled, which is highly practical.

[0026] Reference Figure 1 , Figure 2 A rotating shaft 14 is rotatably mounted on the end of the base 1. A synchronous pulley 13 is sleeved on the outside of the rotating shaft 14 and the first lead screw 6, respectively. A synchronous belt 15 is sleeved on the outside of the two synchronous pulleys 13. A handle is installed on one end of the rotating shaft 14. The rotating shaft 14 can be rotated by using the handle at one end of the rotating shaft 14. Under the transmission of the synchronous pulleys 13 and the synchronous belt 15, the first lead screw 6 can be effectively driven to rotate, and a stable rotation operation can be achieved.

[0027] Reference Figure 1 A support rod 16 is fixedly connected to the lower surface of the base 1, and a universal ball 17 is fixedly connected to the lower end of the support rod 16. The support rod 16 can be used to provide stable support for the base 1, while the universal ball 17 can be used to move the device conveniently.

[0028] Working principle: In use, first place the welding machine in the designated position. Then, select the corresponding size of the first hot melt pipe 11 and the second hot melt pipe 19 according to the required pipe size. Next, install the first hot melt pipe 11 and the second hot melt pipe 19 onto the heating base 10 using bolts. At this point, hot melt welding can be performed. Then, install the pipe and the joint onto the corresponding clamping seats 3. During installation, rotate the clamping screw 5 so that the two clamping plates 4 on the same clamping seat 3 can effectively clamp and fix the pipe and the joint. After clamping, use the handle at one end of the rotating shaft 14 to rotate the rotating shaft 14. Under the transmission of the synchronous pulley 13 and the synchronous belt 15, the first lead screw 6 can be effectively driven to rotate. Since the outer surface of the first lead screw 6 is provided with two types of threads with opposite directions, and the dividing point is the middle position of the first lead screw 6, the rotation of the first lead screw 6 can make the two clamping plates 4 rotate. The pipe and connector on seat 3 are respectively engaged with the second hot melt tube 19 and the first hot melt tube 11. Then, the first resistance heating tube 12 and the second resistance heating tube 18 are activated to raise the temperature of the first hot melt tube 11 and the second hot melt tube 19, thereby enabling the pipe and connector to be hot melted. Then, the first screw 6 is reversed, causing the two clamping seats 3 to move in opposite directions, thereby separating the pipe and connector from the second hot melt tube 19 and the first hot melt tube 11, respectively. Then, the second screw 9 is rotated, causing the heating seat 10 to rise in height. Then, the first screw 6 is rotated again, causing the two clamping seats 3 to move closer together, thereby enabling the pipe and connector to be sleeved and connected. At the same time, the pipe and connector maintain a stable connection force, ensuring that the pipe and connector are firmly connected. After the connection is completed, the clamping screw 5 is loosened, and the welded pipe and connector are unloaded.
