Description
Technical Field
The utility model belongs to the technical field of floor processing machinery, concretely relates to incorgruous parallel building blocks sectional type barrel for double screw extruder.
Background
Both the LVT plastic floor and the SPC floor are one of PVC floors. The main raw materials are polyvinyl chloride, wood powder, calcium powder and the like. The PVC floor is light, thin, wear-resistant, good in elasticity, fireproof, flame-retardant, water-absorbing, moisture-proof, sound-absorbing and noise-preventing, and is particularly simple, convenient and pollution-free in installation. The development of PVC floor is short for several years, and the PVC floor is developed from a single hard floor manufactured by using a marble-imitated effect to a floor manufactured by using various soft and hard walls, a wood-proof floor, a foaming light floor, an environment-friendly methane-free plastic wood grain floor and the like. Has been generally accepted in large and medium cities at home and abroad, and has wide application.
The process of floor production can be summarized as follows: the raw materials are sheared and meshed by a screw in a cylinder of an extruder under the conditions of high temperature and vacuum negative pressure to form paste (called as plasticization), the paste is shaped and extruded into a sheet shape by a die, the sheet is molded by a calender under the condition of hot state, a layer of film which needs to imitate marble or wood grains is coated on the surface of the sheet, and the linen grain (grains are coated on a lower roller) for sticking glue is pressed on the back of the sheet to be used as a base material. And performing wear-resistant protection treatment on the surface of the UV paint coating production line. And then the substrate is subjected to the sectional slotting treatment by a slotting machine, and finally the finished product is packed.
The life of the barrel in the extruder barrel directly determines the quality and yield of the product. Most of the existing extruders in the market are 92/188 counter-rotating conical twin-screw extruders and 110/220 counter-rotating conical twin-screw extruders, or 115 counter-rotating parallel twin-screw extruders, 130 counter-rotating parallel twin-screw extruders and 135 counter-rotating parallel twin-screw extruders.
The cone twin or flat twin extruder has limited output, the maximum such as 135 counter-rotating parallel twin-screw extruder has a cylinder center distance of 110mm, the length-diameter ratio of the screws is 28:1, and the output is 40 tons/day. The remaining yield is smaller. Because the raw material contains a large amount of calcium powder (calcium carbonate), the hardness of the raw material is high, a machine barrel is easy to wear, and the raw material is usually replaced within 3-6 months, so that the cost is too high. Medium and small floor enterprises cannot afford to pay at all. Most of the existing machine barrels are cooled by an external fan, the cooling effect is general, if the machine barrels cannot be cooled in time, the temperature inside the machine barrels is ultrahigh, and the materials are scorched. At this moment, the machine barrel screw needs to be stopped, disassembled and cleaned, and time and labor are wasted.
