Description
Technical Field
The utility model belongs to the technical field of floor processing machinery, concretely relates to screw rod for parallel double screw extruder of incorgruous convenient to change screw element.
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 material is 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, the paste is shaped and extruded into sheets by a die, the sheets are formed by a calender under the condition of hot state, a layer of film with marble or wood texture needs to be imitated is coated on the surface of the sheets, and the rough surface texture (the texture is pressed on a lower roller) for sticking glue on the back of the sheets is 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 working efficiency, the service life and the plasticizing condition of the screw in the barrel of the extruder directly determine the quality and the 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 screw center distance of the 135 counter-rotating parallel twin-screw extruder is 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, the screw is easy to wear, and the raw material is usually replaced within 3 to 6 months, so the cost is too high. The middle and small floor enterprises cannot afford to bear at all, the existing screws on the market are integrally processed, and once the screws are damaged, the screws need to be replaced completely, so that the screws for the counter-rotating parallel double-screw extruder are convenient for replacing thread elements.
