Description
Technical Field
[0001] This utility model relates to the field of pipe cooling, and more specifically, to a cooling device for pipe extrusion equipment. Background Technology
[0002] The cooling system of pipe extrusion equipment is a crucial component in extrusion production. Its main function is to effectively control the temperature changes of the pipe during the extrusion process, ensuring that the formed pipe has stable dimensions, good physical and mechanical properties. The cooling system is usually located at the outlet of the extruder. After the pipe passes through the extrusion die, it needs to be rapidly cooled by the cooling system to solidify it, facilitating subsequent cutting and processing.
[0003] A search revealed that Chinese patent CN208774012U discloses "A pipe extruder with automatic cutting function," which includes a spiral pusher that pushes the material to the extrusion head for extrusion molding. The heating wire in the extrusion head structure ensures uniform flow of the plastic fluid, preventing the fluid from becoming too viscous due to temperature drop and causing blockage. A cooling coil cools the output pipe, ensuring rapid discharge and preventing it from sticking to the inner wall of the extrusion head, further preventing blockage. The extrusion head effectively improves the strength and quality of the extruded pipe. A conveying platform is located on the end of the extrusion head, with a vertical cylinder at its upper end. An infrared sensor detects the pipe and transmits a signal to the vertical cylinder, driving the cutting blade to cut the pipe. The structure is simple, cutting is convenient and efficient, with high working efficiency and low production cost. However, it still has the following drawbacks:
[0004] (1) When using pipe cooling, the above application makes it difficult to guide the pipe during cooling, which may cause the pipe to deviate from the cooling trajectory during cooling.
[0005] The aforementioned applications, when using pipe cooling, make it difficult to treat the pipe surface after cooling is complete, potentially resulting in burrs on the pipe surface. Therefore, a cooling device for pipe extrusion equipment is proposed. Utility Model Content
