A pvc pipe cooling and shaping equipment

Abstract

The invention relates to a PVC (Polyvinyl Chloride) pipe cooling and setting device which comprises a cooling water tank. A water inlet and a water outlet are formed in the cooling water tank; a refrigerator is in pipe connection to the water outlet; a water pump is in pipe connection to the refrigerator; power supplies are externally connected to the refrigerator and the water pump; the water inlet is in pipe connection to one end of the water pump; a water inlet valve is arranged between a pipeline and the water inlet; a sleeve pipe is arranged in the cooling water tank; a blocking ring is arranged on the inner surface of the cooling water tank; a slip railway is arranged between the blocking ring and the cooling water tank; a slip groove corresponding to the slip railway is formed in the blocking ring; the blocking ring is connected with a hand wheel on the outer part of the cooling water tank through the slip railway. According to the technical scheme provided by the invention, theadjustability of a cooling area is improved, the complexity of the equipment structure is reduced, the operation is simple, the cooling uniformity is improved, and the equipment market popularizationcan be improved.

Description

technical field [0001] The invention relates to the technical field of PVC plastic pipes, in particular to a cooling and shaping equipment for PVC plastic pipes. Background technique [0002] PVC material is mainly polyvinyl chloride and is often used to make plastic pipe fittings. Due to the characteristics of light weight, corrosion resistance, beautiful appearance, no bad smell, and easy processing and construction, PVC pipes are widely used in the construction industry. Water supply system pipes, drainage, exhaust and sewage pipes, underground drainage pipes, rainwater pipes, and wire installation for building houses are equipped with threading pipes, etc., with long service life, high corrosion resistance and compressive strength, saving metal, improving living environment, and safety Convenient, favored by the plumbing industry. [0003] In the production process of PVC plastic pipes, after the raw materials are mixed at high speed, the materials are extruded into the...

AI Technical Summary

Problems solved by technology

The cooling and shaping water tank in this technical solution is provided with a water inlet pipe between each adjacent two shaping blocks, so that each cooling cavity has a separate supply of new cooling water, so that the cooling effect of the pipe is better and the profile is prevented. The cooling rate and cooling efficiency in the water tank are inconsistent before and after, and the cooling effect is not good, etc.

In this scheme, cooling cavities of different sizes and numbers are set, and water holes are set in different cooling cavities, and cold water is injected into the water tank through the water inlet pipe on the side wall of the water tank to form a new cooling cavity in each cooling cavity. Separate cooling water supply, this solution will connect multiple water inlet pipes outside the cooling shaped water tank, it is inconvenient to adjust and move the equipment, the water inlet structure is complex, and the inside of the water tank is partitioned by shaped blocks, the number of shaped blocks installed according to The length of the pipe to be cooled cannot be adjusted, the cooling length of the pipe is increased or decreased, and the number of shaped blocks is too small or too large, which cannot adapt to various practical situations and on-site processing requirements, and cannot realize the temperature control of each cooling chamber
