[0001] The utility model relates to the technical field of bamboo fiber pipe production, in particular to a bamboo fiber composite pipe forming temperature control and regulating device. Background Art

[0002] At present, in the production process of bamboo fiber pipes, the raw materials of the pipes need to be hot-melt treated and then pressurized into shape. The process is accompanied by thermoforming treatment, so that the molding temperature of the pipes can be kept uniform and stable during the discharge process.

[0003] Based on the above process requirements, it is necessary to ensure that the temperature state during pipe forming is stable, neither too high nor too low, especially when it comes to the need for temperature control, which needs to be kept as accurate and efficient as possible. Since bamboo fiber is prone to temperature fluctuations during transportation during production, the hot melting speed of the bamboo fiber composite material will significantly increase the risk of combustion. When it reaches its ignition point, it will cause damage to the material at the very least, affecting the quality of pipe forming. At worst, it will cause equipment failure and shutdown, posing a certain degree of safety hazard. In the current bamboo fiber pipe production process, the temperature control part is still solidified, and its temperature control requirements are limited. It is impossible to fully guarantee the uniformity of the overall cycle temperature control, which is likely to affect the forming quality of the pipe and cannot meet current usage needs. Therefore, targeted adjustments are needed. Utility Model Content
