Abstract

The invention discloses a heterodromous parallel double-screw building block type sectional machine barrel which comprises a blanking machine barrel section, a first conventional machine barrel section, an easily-worn machine barrel section, a second conventional machine barrel section, a machine barrel discharging port section and a material plasticizing section of the easily-worn machine barrel section in the incoming material direction of a gas outlet, wherein a discharging port of the machine barrel is divided into the machine barrel discharging port section, and a gas outlet is formed in the second conventional machine barrel section. The invention relates to a building block type sectional machine barrel with counter-rotating parallel double screws, which is characterized in that the front end of an exhaust port of the machine barrel is divided into one to two sections, the discharge port of the machine barrel is divided into one section, the two sections are sections with easy wear of the machine barrel, and only two sections of the machine barrel need to be replaced when the machine barrel is worn and affects production after long-time working, so that the later maintenance cost is greatly reduced.

Description

Incongruous parallel double-screw building block type sectional machine barrel

Technical Field

The invention relates to the field of plastic extruders, in particular to a building block type sectional machine barrel with counter-rotating parallel double screws.

Background

L VT plastic floor and SPC floor are both one kind of PVC floor, its main raw materials are polyvinyl chloride, wood flour and calcium powder etc. PVC floor has light and thin, wear-resisting, good elasticity, fireproof and flame-retardant, water-absorbing and moisture-proof and sound-absorbing and noise-proof functions, especially simple and convenient installation without pollution.

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 directly determines the quality and yield of the product. The machine barrel of the existing extruder on the market is mostly a whole or divided into three sections. 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.

The invention relates to a building block type sectional machine barrel with counter-rotating parallel twin screws, wherein the front end of an exhaust port of the machine barrel (possibly comprising the exhaust port) is divided into one to two small sections, and the discharge port of the machine barrel is divided into a small section. The front end part of the air outlet of the machine barrel is a plasticizing section, so that the accumulation of the formed materials is easy to cause paste and machine blockage after a long time. The rear end of the exhaust port of the machine barrel is an extrusion section, and particularly the joint of a discharge port of the machine barrel and a die has high pressure and large abrasion. If two above-mentioned places go wrong, only need to change two barrels, very big reduction later maintenance's expense.

Disclosure of Invention

The invention aims to solve the defects in the prior art and provides a building block type sectional barrel with counter-rotating parallel double screws.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a parallel twin-screw cordwood system of incorgruous festival barrel, includes blanking barrel section, first conventional barrel section, easy wear barrel section, the conventional barrel section of second, barrel discharge gate section, the material plastify section of the supplied materials direction at the gas vent of the subsection of easy wear barrel section, the discharge gate of barrel will divide a barrel discharge gate section, be provided with the exhaust hole on the conventional barrel section of second.

Preferably, the easy-wear barrel section is arranged in one section or two sections, the length of the easy-wear barrel section in one section is 4-12 screw leads, and the length of each section in two sections is 2-6 screw leads.

Preferably, the length of one section of the discharge opening section of the machine barrel is 2-5 screw leads.

Preferably, the exhaust hole is also arranged on the wearing cylinder section.

Compared with the prior art, the invention has the beneficial effects that: the invention relates to a heterodromous parallel double-screw building block type sectional machine barrel, wherein the front end of an exhaust port of the machine barrel is divided into one to two sections, the discharge port of the machine barrel is divided into one section, the two sections are easy-to-wear sections of the machine barrel, the easy-to-wear section of the machine barrel can be divided into one section or two sections, the length of the one section is 4-12 screw leads, the length of each section divided into two sections is 2-6 leads, if the easy-to-wear section is divided into three or more sections, the distance of each section is too small, cost waste is caused, the discharge port section of the machine barrel is not necessary, the length of the one section is 2-5 screw leads, when the machine barrel is worn and affects production for a long time, only two sections of the machine barrel need to be replaced.
