PVC pipe manufacture machine
The main classification of PVC pipe manufacture machine
PVC pipe manufacture machine is divided into two kinds of RPVC pipes, which is made by mixing PVC resin with stabilizers, lubricants and other additives. It can also be extruded in a single extrusion process.RPVC pipes are resistant to chemical corrosion and insulation and are mainly used for transporting various fluids and used as wire bushing.RPVC pipe is easy to cut, welding, bonding and heating, so it is very convenient to install and use.The SPVC tube is made by adding a large amount of plasticizer and a certain amount of stabilizer and other additives after granulation by PVC resin.SPVC pipe with excellent chemical stability, excellent electrical insulation and good softness and the pigmentation of pipe commonly used as a substitute for rubber hose for conveying liquid and corrosive medium is used for cable and wire insulation casing pipe, etc.
PVC pipe manufacture machine main structure
1. Raw material mixing is PVC stabilizers, plasticizers, antioxidant and other auxiliary materials in proportion, process has added a high-speed mixer Canon of material and mechanical since the temperature of the heat setting process of friction material, and then the cold mixing machine will be reduced to 40-50 degrees, material so that it can be added to the extruder hopper.
2. The extruder part of the machine is equipped with a quantitative feeding device, so that the extrusion quantity and the feeding amount can be matched to ensure the stable extrusion of the product.Due to the characteristics of the conical screw feeding section has a larger diameter on the heat transfer area of the material and the shear velocity is larger for material plasticizing, metering section of screw small diameter reduced the heat transfer area and the melt shear velocity can make the melt extrusion under low temperature.When the screw is rotated inside the cylinder, the PVC is plasticized and pushed to the head to achieve compaction, melting and mixing, and the purpose of exhaust and dehydration is achieved.The feeding device and the screw drive device can realize synchronous speed adjustment by frequency conversion.
3. The extrusion die head is made of PVC with compacted, melting and mixing, and then the extrusion die head of the extrusion die is made of pipe material.
4. Vacuum calibrating tank used for styling, cooling pipes, vacuum system for setting and cooling water tank on the vacuum system and water circulation system, circulating water spray cooling stainless steel enclosure, vacuum system before and after the mobile device mounted on the tank and the left and right sides, high and low adjusting device manually.
5. The tractor is used to continuously and automatically bring the cooled and hardened tube from the nose to the frequency control.
6. After cutting machine according to the required length by travel switch control for automatic cutting and delay over the water production, cutting machine to pronounce long switch signal instructions to complete the whole cutting process in cutting process and pipe run synchronized cutting process completed by electric and pneumatic drive, cutting machine is equipped with suction device will cut the detritus to suck out in time and recovery.
7. Turn rack material movement by cylinder by pneumatic control, is expected to set up there is a limit device when cutting saws to cut off the pipeline after continue to delivery after delay the cylinder into the work to achieve double material discharging action to achieve.After unloading, the time delay is automatically reset to wait for the next cycle.
