Description

Technical Field

[0001] This utility model discloses a heating device for producing carat tubes, belonging to the technical field of auxiliary tools for pipe production. Background Technology

[0002] Krah pipe is a high-density polyethylene spiral wound structured wall pipe formed by hot winding. It is made of high-density polyethylene resin as the main raw material and adopts a hot winding molding process. It is made of polypropylene (PP) single-wall corrugated pipe as the supporting structure and has a high resistance to external pressure. It has the advantages of high weld quality of hot winding molding, excellent installation performance, good flexibility, recyclability of HDPE, corrosion resistance, aging resistance, service life of 50 years, low inner wall roughness, and large water delivery capacity.

[0003] Currently, in the manufacturing process of carat tubes, it is necessary to heat the mold. The traditional heating method is to heat the mold with a flame. However, incomplete combustion of gas occurs during the heating process, resulting in significant resource waste and safety hazards.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] The purpose of this invention is to provide a heating device for producing kraft tubes, which solves the above-mentioned problems and has the effect of reducing the amount of gas used during the heating process.

[0006] This utility model achieves the above-mentioned objectives through the following technical solution: a base and a mold. The base has fixing mechanisms at both its front and rear ends, and the mold is respectively mounted on the two fixing mechanisms at its front and rear ends. A heating mechanism is provided on the side of the base. The heating mechanism includes a heating seat, a first air inlet pipe, a second air inlet pipe, a fuel control box, a first air outlet pipe, and a second air outlet pipe. The heating seat is located on the side of the base, and the fuel control box is located on the upper end of the heating seat. The first and second air outlet pipes extend to the upper and lower ends of the side of the mold, respectively. Both the first and second air outlet pipes are connected to flame nozzles. The fuel control box contains a first mixing chamber and a second mixing chamber. The first air inlet pipe and the first air outlet pipe are connected through the first mixing chamber, and the second air inlet pipe and the second air outlet pipe are connected through the second mixing chamber. The fuel control box has two air pumps respectively connected to the first and second mixing chambers. The fuel control box also has a third air inlet pipe connected to the two air pumps. Finally, the fuel control box has a control module for controlling the two air pumps.

[0007] By adopting the above technical solution, two gas outlet pipes are connected to two flame nozzles to simultaneously heat the upper and lower ends of the mold side, making the mold heat up more evenly and rapidly, thus improving processing efficiency. Furthermore, by setting up a combustion control box, the first and second mixing chambers inside the box can mix the gas introduced through the first and second air inlets with the air introduced through the third air inlet, achieving the optimal combustion ratio before being sprayed out through the first and second gas outlet pipes respectively. This improves gas combustion efficiency and reduces gas consumption during processing. Finally, the air pump and control module allow for convenient adjustment of the air-gas mixing ratio, improving both ease of use and adjustment accuracy.

[0008] Preferably, both the first and second air intake pipes are equipped with solenoid valves, and gas flow meters are installed in the first, second, and third air intake pipes. The gas flow meters and solenoid valves are all connected to the control module.

[0009] By adopting the above technical solution, both the gas flow meter and the solenoid valve are connected to the control module. Through the setting of the solenoid valve and the gas flow meter, the gas flow rate can be precisely controlled and adjusted by the control module, thereby further improving heating efficiency and safety.

[0010] Preferably, the flame nozzle includes a preheating cylinder and an ignition cylinder. The rear ends of the two preheating cylinders are respectively connected to a first exhaust pipe and a second exhaust pipe. A heating wire is provided inside the side wall of the preheating cylinder. The ignition cylinder is located at the front end of the preheating cylinder. A cover plate is provided at the front end of the ignition cylinder. Several flame holes are opened on the cover plate. An ignition needle is provided inside the ignition cylinder.

[0011] By adopting the above technical solution, the preheating cylinder can be heated and heated by the heating wire, so that the gas mixed with air sprayed from the first and second gas outlets can be preheated, and the gas can be fully combusted. The ignition needle in the ignition cylinder can ignite the gas that has been preheated in the preheating cylinder, and then spray it out through the flame holes on the cover plate to heat the mold. The cover plate and the flame holes can make the flame sprayed from the flame nozzle more concentrated and improve the heating efficiency of the flame.

[0012] Preferably, the base is provided with a support frame corresponding to the positions of the two flame nozzles, and the two flame nozzles are mounted on the support frame.

[0013] By adopting the above technical solution, the support frame can support and fix the two flame nozzles, improving the stability of the device during operation.

[0014] Preferably, both fixing mechanisms include a fixing seat and two rolling wheels. The two fixing seats are arranged laterally facing each other at the front and rear ends of the base. Fixing grooves are provided on the left and right sides of the upper end of the two fixing seats. The rolling wheels are rotatably arranged in the fixing grooves. A clamping channel for clamping the mold is formed between the two rolling wheels on the fixing seat. The front and rear ends of the mold are rotatably arranged in the two clamping channels.

[0015] By adopting the above technical solution, the clamping channel formed between the two rollers, through the setting of the fixed base and two rollers, supports and fixes the mold, and can drive the mold to rotate together by driving the rollers to rotate, so that the mold can be heated evenly and the material can be easily wound in the mold during processing. At the same time, the circular rollers make the fixing mechanism adaptable to molds of different sizes, improving the versatility of the device.

[0016] Preferably, the base is equipped with a drive motor that drives the rolling wheels to rotate, and the drive motor is connected to the control module.

[0017] By adopting the above technical solution, the setting of the drive motor makes the rotation of the rolling wheel more stable, and the connection between the drive motor and the control module can realize the automated control of the rolling wheel, reduce manual operation, and improve production efficiency.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, through the two mixing chambers in the gas control box and the inlet and outlet pipes connected to them respectively, and with the air pump and control module installed, the flow rate and mixing ratio of the heated gas can be precisely controlled, thereby achieving the effect of improving gas combustion efficiency and reducing gas consumption.

[0020] Secondly, by setting up a heating seat, an air inlet pipe, an air outlet pipe, a combustion control box, and a flame nozzle, efficient heating of the kraft tube mold can be achieved. The first and second air outlet pipes extend to the upper and lower ends of the mold side, respectively, ensuring uniform heating of the mold and thus improving the production quality and efficiency of kraft tubes.

[0021] Thirdly, the unique design of the flame nozzle includes a preheating cylinder and an ignition cylinder. The preheating cylinder has heating wires installed inside its side wall to preheat the incoming gas, allowing it to reach a better combustion state before entering the ignition cylinder. The ignition cylinder has a cover plate at the front end with several flame holes and an ignition needle inside. This structure helps to make the flame more concentrated and stable, improving heating efficiency.

The front and rear ends of the mold are rotatably set in the clamping channel formed by the rolling wheels. This structure can stably fix the mold, and the setting of the rolling wheels facilitates the rotation and other operations of the mold during the production process, which is conducive to the uniform heating and forming of the kraft tube.

[0028] A heating device for producing carat tubes, such as Figures 1-3As shown, the device includes a base 1 and a mold 2. The base 1 has fixing mechanisms at both its front and rear ends. The mold 2 is mounted on the two fixing mechanisms at its front and rear ends respectively. A heating mechanism is located on the side of the base 1. The heating mechanism includes a heating seat 3, a first air inlet pipe 4, a second air inlet pipe 5, a fuel control box 6, a first air outlet pipe 7, and a second air outlet pipe 8. The heating seat 3 is located on the side of the base 1, and the fuel control box 6 is located on top of the heating seat 3. The first air outlet pipe 7 and the second air outlet pipe 8 extend to the upper and lower ends of the side of the mold 2, respectively. Both the first air outlet pipe 7 and the second air outlet pipe 8 are connected to flame nozzles 10. By setting two air outlet pipes connected to two flame nozzles 10, the upper and lower ends of the side of the mold 2 are heated simultaneously, making the mold 2 heated more evenly and rapidly, thus improving processing efficiency. The fuel control box 6 contains a first mixing chamber and a second mixing chamber. The first air inlet pipe 4 and the first air outlet pipe 7 are connected via... The first mixing chamber is connected, and the second air inlet pipe 5 and the second air outlet pipe 8 are connected through the second mixing chamber. The fuel control box 6 is equipped with two air pumps that are respectively connected to the first mixing chamber and the second mixing chamber. The fuel control box 6 is equipped with a third air inlet pipe 9 that is connected to the two air pumps. The fuel control box 6 is equipped with a control module that controls the two air pumps. By setting up the fuel control box 6, the first mixing chamber and the second mixing chamber inside the fuel control box 6 can mix the gas introduced by the first air inlet pipe 4 and the second air inlet pipe 5 with the air introduced by the third air inlet pipe 9, so that the ratio of gas to air reaches the optimal combustion ratio and is then sprayed out through the first air outlet pipe 7 and the second air outlet pipe 8 respectively. This improves the gas combustion efficiency and reduces the amount of gas used in the processing. Furthermore, the setting of the air pumps and the control module allows for convenient adjustment of the air-gas mixing ratio, improving both the ease of use of the device and the accuracy of adjustment.

[0029] Both the first intake pipe 4 and the second intake pipe 5 are equipped with solenoid valves. Gas flow meters are installed in the first intake pipe 4, the second intake pipe 5, and the third intake pipe 9. The gas flow meters and solenoid valves are all connected to the control module. Through the solenoid valves and gas flow meters, the gas flow rate can be precisely controlled and adjusted by the control module, further improving heating efficiency and safety. The flame nozzle 10 includes a preheating cylinder 1001 and an ignition cylinder 1002. The rear ends of the two preheating cylinders 1001 are connected to the first outlet pipe 7 and the second outlet pipe 8, respectively. A heating wire 11 is installed inside the side wall of the preheating cylinder 1001. The ignition cylinder 1002 is located at the front end of the preheating cylinder 1001. A cover plate 12 is installed at the front end of the ignition cylinder 1002, and several flame holes 13 are opened on the cover plate 12. An ignition needle is installed inside the ignition cylinder 1002. 14. The heating wire 11 can heat the preheating cylinder 1001, so that the gas mixed with air sprayed from the first gas outlet pipe 7 and the second gas outlet pipe 8 can be preheated, and the gas can be fully combusted. The ignition needle 14 in the ignition cylinder 1002 can ignite the gas that has been preheated in the preheating cylinder 1001, and then spray it out through the flame hole 13 on the cover plate 12 to heat the mold 2. The cover plate 12 and the flame hole 13 can make the flame sprayed by the flame nozzle 10 more concentrated and improve the heating efficiency of the flame. The base 1 is provided with a support frame 15 corresponding to the two flame nozzles 10. The two flame nozzles 10 are set on the support frame 15. The support frame 15 can support and fix the two flame nozzles 10, and improve the stability of the device during operation.

[0030] Both fixing mechanisms include a fixed base 16 and two rolling wheels 17. The two fixed bases 16 are laterally arranged facing each other at the front and rear ends of the base 1. Fixing grooves are provided on the left and right sides of the upper end of each fixed base 16. The rolling wheels 17 are laterally rotatable within the fixing grooves. A clamping channel for holding the mold 2 is formed between the two rolling wheels 17 on the fixed base 16. The front and rear ends of the mold 2 are rotatably positioned within the two clamping channels. Through the arrangement of the fixed bases 16 and the two rolling wheels 17, the clamping channel formed between the two rolling wheels 17 supports and fixes the mold 2 while allowing the rolling wheels to be driven to move freely. The rotation of the rotating wheel 17 drives the mold 2 to rotate as well, thereby allowing the mold 2 to be heated evenly and facilitating the winding of materials during processing. At the same time, the circular rolling wheel 17 allows the fixing mechanism to adapt to molds 2 of different sizes, improving the versatility of the device. The base 1 is equipped with a drive motor that drives the rolling wheel 17 to rotate. The drive motor is connected to the control module. The drive motor makes the rotation of the rolling wheel 17 more stable, and the connection between the drive motor and the control module enables automated control of the rolling wheel 17, reducing manual operation and improving production efficiency.

[0031] When producing carat tubes, the corresponding mold 2 is placed at both ends on the fixing mechanisms at the front and rear ends of the base 1. The mold 2 is clamped and fixed by the clamping channel formed by the two rolling wheels 17 on the fixing mechanism. Then, the control module starts the drive motor to drive the rolling wheels 17 to rotate, causing the mold 2 to rotate together. Then, the control module starts the air pump and solenoid valve to introduce air and gas into the first mixing chamber and the second mixing chamber for mixing. Then, the mixture is sprayed out to the flame nozzle 10 through the first gas outlet pipe 7 and the second gas outlet pipe 8. The heating wire 11 in the preheating cylinder 1001 on the flame nozzle 10 can heat the preheating cylinder 1001, thereby preheating the sprayed mixed gas. Finally, the flame is sprayed out from the flame hole 13 on the front cover plate 12 of the ignition cylinder 1002 by the ignition needle 14 in the ignition cylinder 1002 to heat the mold 2. This device achieves the effect of automatically controlling the heating of the mold 2, improving the combustion efficiency of the gas and reducing the amount of gas used.
