Description

Technical Field

[0001] This invention relates to the field of pipe welding, and more specifically, to a horizontal fast-drying machine for non-metallic pipe welding. Background Technology

[0002] In recent years, in construction engineering, especially in mechanical and electrical engineering, the significant increase in material costs and the various drawbacks of using metal materials (such as susceptibility to rust, heavy weight making them difficult to transport, and time-consuming and labor-intensive installation) have led to an increasing number of non-metallic pipes replacing traditional metal pipes for mechanical and electrical pipelines, such as water supply, drainage, and ventilation ducts. Furthermore, with the improvement of material fire resistance limits, non-metallic fire-fighting water pipes are now also appearing in fire protection engineering. Moreover, in certain special fields (such as exhaust systems in laboratories containing acids and alkalis, ultrapure water pipelines, and pipelines handling corrosive fluids), the use of non-metallic pipes is mandatory. It can be said that the application prospects of non-metallic pipes in future construction engineering are very broad.

[0003] However, currently, some existing pipes, after being fused together using special processes, are usually simply left to cool and dry naturally in the air. This method is extremely time-consuming, and the two pipes cannot be moved while the glue is still wet, severely impacting the efficiency of pipe fusion. Therefore, how to invent a horizontal fast-drying machine for non-metallic fusion pipes to improve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a horizontal fast-drying machine for non-metallic welded pipes, which aims to improve the problem that the current pipe welding process usually uses natural air cooling, resulting in low efficiency for workers to weld pipes.

[0005] This invention is implemented as follows: This invention provides a horizontal fast-drying machine for non-metallic welded pipes, including a mounting base plate. Adjustable seats are fixedly mounted on both sides of the upper end surface of the mounting base plate, and a heating device is fixedly mounted in the middle of the upper end surface of the mounting base plate. The machine also includes: An adjustment mechanism is provided in the inner cavity of the adjustment seat and is used to support the pipeline; A rotating mechanism is provided, which is located between the adjusting seats on the left and right sides, and is used to rotate the pipe. A drying mechanism is installed inside the heating device and is used to dry the welded joints of the pipes.

[0006] Preferably, the adjustment mechanism includes a first bevel gear and a second bevel gear rotatably mounted in the inner cavity of the adjustment seat. A cross handle is fixedly mounted on the right side wall of the first bevel gear, and a threaded rod is fixedly mounted on the side wall of the second bevel gear. A sliding seat is threaded onto the side wall of the threaded rod.

[0007] By adopting the above technical solution, the distance between the sliding seats on both sides can be adjusted, thus making the entire device suitable for use with pipes of different inner diameters.

[0008] Preferably, the cross grip is connected through the adjustment seat, and two second bevel gears are provided in the inner cavity of each adjustment seat. The first bevel gear and the second bevel gear are meshed and connected. The sliding seat is slidably connected to the adjustment seat, and the threaded rods on the front and rear sides of the same adjustment seat inner cavity have opposite thread directions.

[0009] Preferably, the rotating mechanism includes a support seat fixedly installed on the side wall of the adjusting seat, and a limiting wheel rotatably installed in the inner cavity of the support seat, with a transmission rod fixedly installed between the limiting wheels on the left and right sides.

[0010] By adopting the above technical solution, the two pipes that are fused together can be rotated, which avoids the joint of the pipes being constantly heated, thus improving the quality and efficiency of pipe fusion.

[0011] Preferably, there are a total of 4 support seats, at least one of which is equipped with a drive motor, and the output shaft of the drive motor is fixedly connected to the rotating shaft of the corresponding limiting wheel. The arc surface of the limiting wheel is provided with anti-slip texture.

[0012] Preferably, the drying mechanism includes a transmission worm gear fixedly installed in the middle of the side wall of the transmission rod, and a uniform heat dissipation device fixedly installed in the middle of the inner cavity of the heating device. A support plate is fixedly installed between the sliding seats on the left and right sides. A fixed seat is fixedly installed on the upper end surface of the support plate. A transmission worm wheel is rotatably installed in the inner cavity of the fixed seat. An output rod is fixedly installed in the inner cavity of the transmission worm wheel.

[0013] Preferably, the transmission worm gear is meshed with the transmission worm wheel, and a heating source, preferably an electric heating device, is placed on the lower end face of the uniform heat dissipation device. The uniform heat dissipation device is provided with several arc-shaped grooves. A scraping mechanism is provided on the inner end of the output rod. The scraping mechanism includes a reciprocating screw threaded into the inner cavity of the output rod and an elastic scraper fixedly installed at the end of the reciprocating screw. A limiting plate is fixedly installed on the outer wall of the reciprocating screw, and a limiting rod is slidably installed in the inner cavity of the limiting plate. The end of the limiting rod is fixedly installed on the side wall of the fixed seat.

[0014] By adopting the above technical solution, the elastic scraper can slide on the bonding part of the pipe to scrape off excess adhesive, thereby improving the curing effect of the adhesive at the bonding part of the pipe.

[0015] Preferably, an airflow enhancement mechanism is provided on the side wall of the fixed base. The airflow enhancement mechanism includes a cam fixedly installed on the outer end of the output rod and a pressure accumulator fixedly installed on the side wall of the fixed base. A piston plate is slidably installed in the inner cavity of the pressure accumulator. A piston column is fixedly installed on the upper end face of the piston plate. A return spring is fixedly installed on the lower end face of the piston plate. An air inlet pipe is fixedly connected to the lower end face of the pressure accumulator, and the other end of the air inlet pipe is fixedly connected to the lower side wall of the heating device.

[0016] By adopting the above technical solution, air can enter the lower part of the heating device through the air inlet pipe, which increases the airflow and heat circulation in the heating device and improves the drying effect of the heating device.

[0017] Preferably, the cam is in contact with the side wall of the piston rod, the other end of the return spring is fixedly installed on the bottom surface of the inner cavity of the accumulator box, the piston rod is connected through the accumulator box, and the air intake pipe is a flexible pipe.

[0018] Preferably, the accumulator box has air inlets on its front and rear side walls, and a one-way valve is provided at the air inlet to the inner cavity of the accumulator box. The two ends of the air inlet pipe are respectively connected to the accumulator box and the heating device, and a one-way valve is provided in the inner cavity of the air inlet pipe to the inner cavity of the heating device.

[0019] Preferably, based on the above description of a horizontal quick-drying machine for non-metallic welded pipes, the steps for using this machine are as follows: Step 1: Adjust the applicable pipe diameter. Rotate the cross handle to rotate the first bevel gear. Since the first bevel gear meshes with the second bevel gear, the second bevel gears on both sides can rotate, causing the threaded rods fixedly installed on their side walls to rotate. Since the threaded rods on both sides have opposite thread directions and are threadedly connected to the sliding seats, when the threaded rods on both sides rotate, the sliding seats on both sides will move closer or further away from each other simultaneously. As a result, the distance between the support seats fixedly installed on the side walls of the sliding seats also changes accordingly. Thus, as described above, workers can easily and quickly change the distance between the limit wheels on both sides to accommodate pipes with different inner diameters, improving the practicality of the entire equipment. Step Two: Install an internal support device for the pipeline. The internal support device includes a main shaft with at least one support rod rotatably connected to it. Each support rod is rotatably connected to a connecting rod, which is further connected to the main shaft. The main shaft also has a transmission device. This transmission device, through the operation of an adjustment device, can raise and lower the connecting rods in conjunction with the operation of the support rods. The other end of each support rod is rotatably connected to a support head. The support head supports the inner wall of the pipeline and has an angle adjustment function, allowing for better contact with the inner wall and providing better support. In use, the internal support device is placed into the pipeline to be welded. The adjustment device is controlled to raise the connecting rods and open the support rods, allowing the support heads to support the inner wall of the pipeline to be welded. Preferably, the main shaft can display the pressure status of each support head to determine the force exerted on the pipeline by each support head. After the pipe to be welded is completed, the connecting rod is raised and the support rod is retracted through the remote reset device via wireless connection, so that the support head no longer supports the inner wall of the pipe, making it convenient to remove the inner support device.Step 3: Place the pipes to be welded. After placing the two pipes to be welded on the walls of the left and right limit wheels respectively, start the drive motor installed on the limit wheels to rotate any one of the limit wheels. Under the limiting action of the transmission rod, the left and right limit wheels at the front or rear will rotate in the same direction. Since the arc surface of the limit wheels is provided with anti-slip texture, the friction coefficient of each limit wheel arc surface is relatively large at this time, that is, the limit wheels can drive the pipe to rotate. Step 4: Heat the pipes to be welded. The heating device controls the appropriate heat. The hot air generated by the heating device rises and dries the continuously rotating pipe welding part. Thus, through the above, the entire equipment can evenly dry the pipe welding part, accelerate the solidification of the adhesive at the pipe welding part, and thus greatly improve the quality of pipe welding by the workers. Step 5: Scrape off the excess adhesive. Fix the transmission rod between the limit wheels on both sides. At this time, the front and rear limit wheels on both sides can drive the transmission rod to rotate, and at the same time fix the... The transmission worm gear mounted on the transmission rod also rotates, driving the transmission worm wheel to rotate continuously. An output rod is fixedly installed inside the transmission worm wheel, causing it to rotate. With the limit rod limiting the reciprocating screw via the limit plate, the reciprocating screw slides back and forth inside the output rod's cavity when the output rod rotates. When the elastic scraper fixed to the reciprocating screw first contacts the pipe, the reciprocating screw can still slide towards the pipe, while the elastic scraper remains pressed against the pipe's side wall. As the pipe rotates, the fixed-position elastic scraper effectively removes excess adhesive from the pipe joint, improving the curing effect of the adhesive at the pipe's joint. Simultaneously, when the reciprocating screw moves in the opposite direction to the pipe, the elastic scraper disengages from the pipe's side wall, and excess adhesive scraped from the pipe rolls off the inclined side wall of the elastic scraper, keeping the scraped area clean and ensuring the quality of subsequent wiping of the pipe's side wall by the elastic scraper. Step Six: After completing the pipe welding, remove the inner support device. The inner support device has a remote reset device. The remote reset device, through a wireless connection, causes the connecting rod to rise and the support rod to retract, so that the support head no longer supports the inner wall of the pipe, making it easy to remove the inner support device.

[0020] The beneficial effects of this invention are: 1. The worker rotates the cross handle to make the first bevel gear rotate. With the cooperation of the second bevel gear and the threaded rod, the sliding seats on both sides will move closer or further apart simultaneously. At this time, the distance between the support seats fixed on the side wall of the sliding seat also changes accordingly. Thus, as described above, the worker can easily and quickly change the distance between the limit wheels on both sides to suit the placement of pipes with different inner diameters, improving the practicality of the entire equipment. After the worker places the two pipes to be welded on the surface of the limit wheels on the left and right sides respectively, the worker starts the drive motor installed on the limit wheels to make any one of the limit wheels rotate. With the cooperation of the rotation mechanism, the limit wheel can drive the pipe to rotate. With the heat continuously radiating upward from the heating device, the pipe welding part can be dried evenly, accelerating the solidification of the adhesive at the pipe welding part, thereby greatly improving the quality of pipe welding by the worker. At the same time, with the cooperation of the scraping mechanism, excess adhesive at the pipe bonding part can be scraped off to improve the effect and speed of adhesive curing at the pipe bonding part.

[0021] 2. When the limit wheel rotates, the drying fan fixedly connected to the end of the output rod also rotates continuously due to the airflow enhancement mechanism, increasing the horizontal airflow. This allows air containing a certain amount of heat to be blown onto the fusion joint of the two pipes, further improving the drying efficiency of the pipes. At the same time, the cam fixed to the other end of the output rod continuously squeezes the piston plate, causing the air in the lower cavity of the accumulator box to enter the heating device through the air inlet pipe. At this time, the airflow in the lower cavity of the heating device increases, and the flowing air can blow on the heating device, realizing the function of a blower. This accelerates the heat conversion, ensuring that the heating device can generate enough heat waves to transfer upwards to dry the pipes, thereby further improving the overall efficiency of the pipe fusion process.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example Reference Figure 1-12 A horizontal fast-drying machine for non-metallic welded pipes includes a mounting base plate 1, with adjusting seats 2 fixedly mounted on both sides of the upper end surface of the mounting base plate 1, and a heating device 3 fixedly mounted in the middle of the upper end surface of the mounting base plate 1. It also includes: Adjustment mechanism 4 is installed in the inner cavity of adjustment seat 2 and is used to support the pipeline; Rotating mechanism 5 is located between the adjusting seats 2 on the left and right sides. Rotating mechanism 5 is used to rotate the pipe. The drying mechanism 6 is installed inside the heating device 3 and is used to dry the welded joints of the pipes.

[0028] Reference Figure 1-2 Furthermore, the adjustment mechanism 4 includes a first bevel gear 41 and a second bevel gear 42 rotatably mounted inside the adjustment seat 2. A cross handle 43 is fixedly mounted on the right side wall of the first bevel gear 41, and a threaded rod 44 is fixedly mounted on the side wall of the second bevel gear 42. A sliding seat 45 is threaded onto the side wall of the threaded rod 44. The cross handle 43 is connected through the adjustment seat 2. Two second bevel gears 42 are provided in each cavity of the adjustment seat 2. The first bevel gear 41 and the second bevel gear 42 are meshed together, and the sliding seat 45 is slidably connected to the adjustment seat 2. The threaded rods 44 on the front and rear sides of the same cavity of the adjustment seat 2 have opposite thread directions.

[0029] It should be noted that: before drying the welded part of the pipe (e.g. Figure 6-7As shown), the worker first rotates the cross handle 43 to rotate the first bevel gear 41. Since the first bevel gear 41 meshes with the second bevel gear 42, the second bevel gears 42 on both sides can rotate, causing the threaded rods 44 fixedly installed on their side walls to rotate. Since the threads of the threaded rods 44 on both sides are opposite in direction, and the threaded rods 44 are threadedly connected to the sliding seats 45, when the threaded rods 44 on both sides rotate, the sliding seats 45 on both sides will move closer or further away from each other at the same time. Thus, the distance between the support seats 51 fixedly installed on the side walls of the sliding seats 45 also changes accordingly. Therefore, through the above-described method, the worker can easily and quickly change the distance between the limit wheels 52 on both sides to adapt to the placement and use of pipes with different inner diameters, thereby improving the practicality of the entire equipment.

[0030] Reference Figure 1-3 Furthermore, the rotating mechanism 5 includes a support seat 51 fixedly installed on the side wall of the adjusting seat 2, and a limiting wheel 52 rotatably installed in the inner cavity of the support seat 51. A transmission rod 53 is fixedly installed between the limiting wheels 52 on the left and right sides. There are a total of 4 support seats 51, and at least one support seat 51 is equipped with a drive motor. The output shaft of the drive motor is fixedly connected to the rotating shaft of the corresponding limiting wheel 52. The arc surface of the limiting wheel 52 is provided with anti-slip texture. The drying mechanism 6 includes a transmission worm gear 61 fixedly installed in the middle of the side wall of the transmission rod 53, and a uniform heat dissipation device 62 fixedly installed in the middle of the inner cavity of the heating device 3. A support plate 63 is fixedly installed between the sliding seats 45 on the left and right sides. A certain feature is fixedly installed on the upper end face of the support plate 63. A fixed base 64 has a transmission worm gear 65 rotatably mounted inside its cavity. An output rod 66 is fixedly mounted inside the transmission worm gear 65. A transmission worm 61 meshes with the transmission worm gear 65. A heating source is placed on the upper end face of a uniform heat dissipation device 62. Several arc-shaped grooves are provided on the uniform heat dissipation device 62. A scraping mechanism 67 is provided on the inner end of the output rod 66. The scraping mechanism 67 includes a reciprocating screw 671 threaded into the inner cavity of the output rod 66 and an elastic scraper 672 fixedly mounted on the end of the reciprocating screw 671. A limiting plate 673 is fixedly mounted on the outer wall of the reciprocating screw 671. A limiting rod 674 is slidably mounted inside the cavity of the limiting plate 673. The end of the limiting rod 674 is fixedly mounted on the side wall of the fixed base 64.

[0031] It should be noted that after the worker places the two pipes to be welded on the walls of the left and right limit wheels 52 respectively, the drive motor installed on the limit wheels 52 is started to rotate any one of the limit wheels 52. Under the limiting action of the transmission rod 53, the left and right limit wheels 52 at the front or rear will rotate in the same direction. Since the arc surface of the limit wheel 52 is provided with anti-slip texture, the friction coefficient of each limit wheel 52 arc surface is relatively large at this time. That is, the limit wheel 52 can drive the pipe to rotate. At this time, the hot air generated by the heating device 3, which is controlled at an appropriate temperature, rises and dries the continuously rotating pipe welding part. Thus, through the above-mentioned process, the entire equipment can evenly dry the pipe welding part, accelerate the coagulation of the adhesive at the pipe welding part, and thus greatly improve the efficiency. The quality of the welded pipe is determined by the transmission rod 53, which is fixedly connected to the limiting wheels 52 on both sides. At this time, the limiting wheels 52 on both sides drive the transmission rod 53 to rotate, and the transmission worm gear 61 fixedly installed on the transmission rod 53 also rotates, causing the transmission worm wheel 65 to rotate continuously. An output rod 66 is fixedly installed inside the transmission worm wheel 65, thus the output rod 66 rotates. Under the limiting action of the limiting rod 674 and the limiting plate 673 on the reciprocating screw 671, when the output rod 66 rotates, the reciprocating screw 671 slides back and forth inside the output rod 66. When the elastic scraper 672 fixedly installed on the reciprocating screw 671 first contacts the pipe, the reciprocating screw 671 can still slide towards the pipe, but at this time the elastic scraper 672 will still be pressed against the side wall of the pipe (e.g., Figure 10 As shown), with the continuously rotating pipe, and in conjunction with the fixed-position elastic scraper 672, excess adhesive at the pipe joint can be scraped off, thereby improving the adhesive curing effect at the pipe joint. Simultaneously, when the reciprocating screw 671 moves in the opposite direction of the pipe (as shown), Figure 11 As shown), at this point, the elastic scraper 672 disengages from the side wall of the pipe, and the excess adhesive balls (blocks) scraped off from the pipe will roll off the inclined side wall of the elastic scraper 672, so that the scraped area of ​​the elastic scraper 672 remains clean, thereby ensuring the quality of subsequent use of the elastic scraper 672 to wipe the side wall of the pipe.

[0032] Reference Figure 1-9Furthermore, an airflow enhancement mechanism 7 is provided on the side wall of the fixed base 64. The airflow enhancement mechanism 7 includes a cam 71 fixedly installed on the outer end of the output rod 66, and a pressure accumulator 72 fixedly installed on the side wall of the fixed base 64. A piston plate 73 is slidably installed in the inner cavity of the pressure accumulator 72. A piston column 74 is fixedly installed on the upper end face of the piston plate 73, and a return spring 75 is fixedly installed on the lower end face of the piston plate 73. An air inlet pipe 76 is fixedly connected to the lower end face of the pressure accumulator 72, and the other end of the air inlet pipe 76 is fixedly connected to the heating device 3. On the lower side wall, the cam 71 is in contact with the side wall of the piston column 74. The other end of the return spring 75 is fixedly installed on the bottom surface of the inner cavity of the accumulator box 72. The piston column 74 is connected to the accumulator box 72 through. The air inlet pipe 76 is a soft pipe. The front and rear side walls of the accumulator box 72 are provided with air inlet holes 721. A one-way air valve with an outlet to the inner cavity of the accumulator box 72 is provided at the air inlet hole 721. The two ends of the air inlet pipe 76 are respectively connected to the accumulator box 72 and the heating device 3, and a one-way air valve with an outlet to the inner cavity of the heating device 3 is provided in the inner cavity of the air inlet pipe 76.

[0033] It should be noted that when the output rod 66 rotates, the cam 71, which is fixedly installed at the other end of the output rod 66, also rotates. Through the setting of the return spring 75, the piston plate 73 is fixedly connected to the piston column 74, and the piston column 74 is connected through the accumulator box 72. Therefore, the return spring 75 can press the piston plate 73 upwards. At this time, the side wall of the piston column 74 will always be in contact with the cam 71. Thus, when the cam 71 rotates, it can continuously press the piston column 74, causing the piston plate 73 to move up and down continuously. When the piston plate 73 moves from top to bottom (e.g....), Figure 8 As shown), the effective volume of the lower cavity of the accumulator box 72 continuously decreases, and the return spring 75 is compressed. At this time, the air pressure inside the accumulator box 72 will continuously increase, eventually breaking through the one-way air valve in the inner cavity of the air inlet pipe 76 and entering the heating device 3. At this time, the air flow rate in the lower inner cavity of the heating device 3 increases, and the flowing air can blow away the heat, realizing the function of a blower, which can accelerate the transfer and dissipation of heat, so as to ensure that the heating device 3 can generate enough heat waves to transfer upward to dry the pipe, thereby further improving the efficiency of the entire equipment in welding the pipe; when the piston plate 73 moves from bottom to top (e.g. Figure 9 As shown, the reset spring 75 is reset, and the effective volume of the lower cavity of the accumulator box 72 continuously increases. The pressure of the air inside the accumulator box 72 will continuously decrease until it is less than the atmospheric pressure of the outside air. At this time, the outside air can enter the lower cavity of the accumulator box 72 through the air inlet 721 to replenish the air in the lower cavity of the accumulator box 72, so that the accumulator box 72 can intermittently and continuously increase the air flow and blow air into the heating device 3, ensuring the continuous operation of the entire equipment.

[0034] The working principle of this horizontal fast-drying machine for non-metallic welded pipes: Before drying the welded parts of the pipe (e.g.) Figure 6-7 As shown), the worker first rotates the cross handle 43 to rotate the first bevel gear 41. Since the first bevel gear 41 meshes with the second bevel gear 42, the second bevel gears 42 on both sides can rotate, causing the threaded rods 44 fixedly installed on their side walls to rotate. Since the threads of the threaded rods 44 on both sides are opposite in direction, the threaded rods 44 are threadedly connected to the sliding seats 45. That is, when the threaded rods 44 on both sides rotate, the sliding seats 45 on both sides will move closer or further away from each other at the same time. Thus, the distance between the support seats 51 fixedly installed on the side walls of the sliding seats 45 also changes accordingly. Therefore, through the above description, the worker can easily and quickly change the distance between the limit wheels 52 on both sides to suit the placement and use of pipes with different inner diameters, improving the practicality of the entire equipment. After the worker places the two pipes to be welded on the walls of the left and right limit wheels 52 respectively, the worker starts the drive motor installed on the limit wheels 52 to make one of the limit wheels 52 rotate. Under the limiting action of the transmission rod 53, the left and right limit wheels 52 at the front or rear will rotate in the same direction. Since the arc surface of the limit wheel 52 is provided with anti-slip texture, the friction coefficient of each limit wheel 52 arc surface is relatively large at this time. That is, the limit wheel 52 can drive the pipe to rotate. At this time, the heating device 3 controls the appropriate heat. The hot air generated by the heating device rises and dries the continuously rotating pipe welding part. Thus, through the above, the entire equipment can evenly dry the pipe welding part, accelerate the solidification of the adhesive at the pipe welding part, and thus greatly improve the quality of pipe welding by the worker. It should be noted that, compared with the firewood drying device, the use of heating device 3 reduces smoke emissions and the impact of smoke on the device, making it more practical and convenient to use with better temperature control.

[0035] The transmission rod 53 is fixedly connected between the limiting wheels 52 on both sides. At this time, the limiting wheels 52 on the front and rear sides can drive the transmission rod 53 to rotate. At the same time, the transmission worm gear 61 fixedly installed on the transmission rod 53 also rotates, driving the transmission worm wheel 65 to rotate continuously. The output rod 66 is fixedly installed in the inner cavity of the transmission worm wheel 65, so the output rod 66 will rotate. Under the limiting action of the limiting rod 674 and the limiting plate 673 on the reciprocating screw 671, when the output rod 66 rotates, the reciprocating screw 671 will slide back and forth in the inner cavity of the output rod 66. When the elastic scraper 672 fixedly installed on the reciprocating screw 671 first contacts the pipeline, the reciprocating screw 671 can still slide towards the pipeline. However, at this time, the elastic scraper 672 will still be pressed against the side wall of the pipeline (e.g., Figure 10As shown), with the continuously rotating pipe, and in conjunction with the fixed-position elastic scraper 672, excess adhesive at the pipe joint can be scraped off, improving the adhesive curing effect at the pipe joint. Simultaneously, when the reciprocating screw 671 moves in the opposite direction of the pipe (as shown), Figure 11 As shown), at this time, the elastic scraper 672 is no longer in contact with the side wall of the pipe, and the excess adhesive balls (blocks) scraped off from the pipe will roll off the inclined side wall of the elastic scraper 672, so as to keep the scraped area of ​​the elastic scraper 672 clean, thereby ensuring the quality of subsequent use of the elastic scraper 672 to wipe the side wall of the pipe. When the output rod 66 rotates, the cam 71, which is fixedly installed at the other end of the output rod 66, also rotates. Through the setting of the return spring 75, the piston plate 73 is fixedly connected to the piston column 74, and the piston column 74 is connected through the accumulator box 72. Thus, the return spring 75 can press the piston plate 73 upward. At this time, the side wall of the piston column 74 will always be in contact with the cam 71. Thus, when the cam 71 rotates, the cam 71 can continuously press the piston column 74, causing the piston plate 73 to move up and down continuously. When the piston plate 73 moves from top to bottom (e.g.) Figure 8 As shown), the effective volume of the lower cavity of the accumulator box 72 continuously decreases, and the return spring 75 is compressed. At this time, the pressure of the air inside the accumulator box 72 will continuously increase, eventually breaking through the one-way air valve set in the inner cavity of the air inlet pipe 76 and entering the heating device 3. At this time, the airflow conversion rate of the lower inner cavity of the heating device 3 is increased to ensure that the heating device 3 can generate enough heat waves to transfer upward to dry the pipe, thereby further improving the efficiency of the entire equipment in welding the pipe. When the piston plate 73 moves from bottom to top (e.g.) Figure 9 As shown), the reset spring 75 is reset, and the effective volume of the lower cavity of the accumulator box 72 continuously increases. The pressure of the air inside the accumulator box 72 will continuously decrease until it is less than the atmospheric pressure of the outside air. At this time, the outside air can enter the lower cavity of the accumulator box 72 through the air inlet 721 to replenish the air in the lower cavity of the accumulator box 72, so that the accumulator box 72 can intermittently and continuously increase the airflow conversion rate into the heating device 3, ensuring the continuous operation of the entire device.

[0036] Furthermore, the system also includes an internal support device 111 for the pipeline. This internal support device includes a main shaft 112, on which at least three support rods 114 are rotatably connected. Each support rod 114 is rotatably connected to a connecting rod 115, which is further connected to the main shaft 112. The main shaft 112 also has a transmission device 116. The transmission device 116, through the operation of an adjustment device 117, can coordinate the raising and lowering of the connecting rods 115 and control the support rods 114. The other end of each support rod is rotatably connected to a support head 113. The support head 113 supports the inner wall of the pipeline and has an angle adjustment function, allowing for better contact with the inner wall and providing better support. The internal support device 111 has a remote reset device. This remote reset device, via wireless connection, raises the connecting rods 115 and retracts the support rods 114, thereby removing the support head 113 from the inner wall of the pipeline, facilitating the removal of the internal support device.

[0037] In use, the inner support devices 111 are placed into the pipes to be welded. The control adjustment device 117 raises the connecting rod 115 and opens the linked support rod 114, allowing the support head 113 to support the inner wall of the pipe to be welded. Preferably, the main shaft can have a sensor device for the pressure condition of each support head 113. This device is not shown in the drawings, but it makes the entire device clear to those skilled in the art, allowing them to determine the force on each support head 113 of the pipe to be welded. After the pipes to be welded are completed, the remote reset device, via wireless connection, raises the connecting rod 115 and retracts the support rod 114, so that the support head 113 no longer supports the inner wall of the pipe, facilitating the removal of the inner support device.

[0038] Based on the above description of a horizontal quick-drying machine for non-metallic welded pipes, the steps for using this machine are as follows: Step 1: Adjust the applicable pipe diameter. By rotating the cross handle 43, the first bevel gear 41 rotates. Since the first bevel gear 41 meshes with the second bevel gear 42, the second bevel gears 42 on both sides rotate, causing the threaded rods 44 fixedly installed on their side walls to rotate. Since the threads of the threaded rods 44 on both sides are opposite in direction, and the threaded rods 44 are threadedly connected to the sliding seats 45, when the threaded rods 44 on both sides rotate, the sliding seats 45 on both sides will move closer or further away from each other. As a result, the distance between the support seats 51 fixedly installed on the side walls of the sliding seats 45 also changes accordingly. Thus, as described above, workers can easily and quickly change the distance between the limit wheels 52 on both sides to accommodate pipes with different inner diameters, improving the practicality of the entire equipment.

[0039] Step 2: Install an internal support device 111 for the pipeline. The internal support device includes a main shaft 112, on which at least three support rods 114 are rotatably connected. Each support rod 114 is rotatably connected to a connecting rod 115, which is further connected to the main shaft 112. The main shaft 112 also has a transmission device 116. The transmission device 116 can raise and lower the connecting rods 115 in conjunction with the operation of the adjustment device 117, and also control the support rods 114. The other end of each support rod is rotatably connected to a support head 113. The support head 113 is used to support the inner wall of the pipeline and has an angle adjustment function, which can better fit the inner wall of the pipeline and provide better support.

[0040] During use, the inner support devices 111 are placed into the pipes to be welded. The control adjustment device 117 raises the connecting rod 115 and opens the linked support rod 114, allowing the support head 113 to support the inner wall of the pipe to be welded. Preferably, the main shaft can have a sensor device for the pressure condition of each support head 113. This device is not shown in the drawings, but it makes the entire device clear to those skilled in the art, allowing them to determine the force on each support head 113 of the pipe to be welded. After the pipes to be welded are completed, the remote reset device, via wireless connection, raises the connecting rod 115 and retracts the support rod 114, so that the support head 113 no longer supports the inner wall of the pipe, facilitating the removal of the inner support device.

[0041] Step 3: Place the pipes to be welded. After placing the two pipes to be welded on the surface of the left and right limit wheels 52 respectively, start the drive motor installed on the limit wheels 52 to rotate any one of the limit wheels 52. Under the limiting action of the transmission rod 53, the left and right limit wheels 52 at the front or rear will rotate in the same direction. Since the arc surface of the limit wheels 52 is provided with anti-slip texture, the coefficient of friction of the arc surface of each limit wheel 52 is relatively large at this time, that is, the limit wheels 52 will be able to drive the pipes to rotate. Step 4: Heat the pipe to be welded. The heating device 3 controls the appropriate heat. The hot air generated by the heating device rises and dries the continuously rotating pipe welding part. Thus, through the above, the entire equipment can evenly dry the pipe welding part, accelerate the solidification of the adhesive at the pipe welding part, and greatly improve the quality of pipe welding performed by workers. Step 5: Scrape off excess adhesive. The transmission rod 53 is fixedly connected between the limiting wheels 52 on both sides. At this time, the limiting wheels 52 on the front, rear, left, and right sides can drive the transmission rod 53 to rotate. Simultaneously, the transmission worm gear 61 fixedly installed on the transmission rod 53 also rotates, driving the transmission worm wheel 65 to rotate continuously. An output rod 66 is fixedly installed in the inner cavity of the transmission worm wheel 65, thus the output rod 66 will rotate. Under the limiting action of the limiting rod 674 and the limiting plate 673 on the reciprocating screw 671, when the output rod 66 rotates, the reciprocating screw 671 will slide back and forth in the inner cavity of the output rod 66. When the elastic scraper 672 fixedly installed on the reciprocating screw 671 first contacts the pipe, the reciprocating screw 671 can still slide towards the pipe. However, at this time, the elastic scraper 672 will still be pressed against the side wall of the pipe (e.g., Figure 10 As shown), with the continuously rotating pipe, and in conjunction with the fixed-position elastic scraper 672, excess adhesive at the pipe joint can be scraped off, thereby improving the adhesive curing effect at the pipe joint. Simultaneously, when the reciprocating screw 671 moves in the opposite direction of the pipe (as shown), Figure 11 As shown), at this point, the elastic scraper 672 disengages from the side wall of the pipe, and the excess adhesive balls (blocks) scraped off from the pipe will roll off the inclined side wall of the elastic scraper 672, so that the scraped area of ​​the elastic scraper 672 remains clean, thereby ensuring the quality of subsequent use of the elastic scraper 672 to wipe the side wall of the pipe.

[0042] Step 6: After completing the pipe welding, remove the inner support device 111. The inner support device 111 has a remote reset device. The remote reset device, through wireless connection, causes the connecting rod 115 to rise and the support rod 114 to retract, so that the support head 113 no longer supports the inner wall of the pipe, making it convenient to remove the inner support device.
