Abstract
The utility model discloses a double-layer slotting charging barrel, which comprises a barrel body and a barrel cavity, wherein the barrel body comprises an outer barrel and inner barrel, the barrel cavity is arranged in the inner barrel, and the barrel cavity wall of the inner barrel is provided with a plurality of longitudinal grooves. The double-layer slotting charging barrel has the advantages that tangential friction coefficient at the inner surface of the inner barrel is increased, materials can be fully melted, the transport rate is high, the sensibility due to the pressure change from the lead output of a non-slotting charge barrel to a machine head is small, the production efficiency is high, and the inner barrel can be replaced when being damaged.
Description
Technical field:
The utility model relates to a kind of extrusion equipment barrel, particularly a kind of double-deck fluting barrel.
Background technology:
Barrel is finished Solid Conveying and Melting, fusion and quantitatively level pressure conveying effect to plastics jointly as the part of extrusion molding extrusion system and screw rod.The version of barrel is related to stability and the uniformity that heat transmits, and influences the Solid Conveying and Melting rate.Barrel of the prior art is generally monoblock type barrel structure, easily guarantee higher manufacturing and assembly precision, simplify assembly work, be convenient to the setting and the dismounting of heating and cooling system, and heat distributes more even vertically, but the process equipment of this barrel is had relatively high expectations, and is difficult to repair again after the inner surface wearing and tearing; The combined type barrel is also arranged, it is combined by several sections barrels, after certain section barrel inner surface wearing and tearing, as long as change this section barrel that damages, but adopting flange bolt to connect each section of combined type material more, be difficult to keep heating uniformity, increase heat loss, the setting and the inconvenient maintenance of heating and cooling system.Simultaneously, because the tangent direction friction coefficient of the inner surface of above-mentioned barrel is little, material is melt and dissolved insufficient, influences the extrusion molding product quality; As under the constant situation of barrel temperature, make material fully melt and dissolved, will increase the friction of screw rod to material, screw rod is fragile.
Summary of the invention:
Be to solve the deficiencies in the prior art, the utility model provides a kind of tangent direction friction coefficient that can increase the inner surface of barrel, make that material is fully melt and dissolved, inner core damages removable double-deck fluting barrel.
The technical problems to be solved in the utility model is achieved through the following technical solutions, double-deck fluting barrel, comprise cylindrical shell and tube chamber, it is characterized in that: described cylindrical shell comprises the urceolus of steel and the inner core of alloy steel, described tube chamber is arranged in the inner core, and the tube chamber wall of described inner core is provided with several longitudinal grooves.
Described groove be shaped as rectangle.
Described groove be shaped as triangle.
Being shaped as of described groove is trapezoidal.
The utility model compared with prior art, the barrel cylindrical shell is set to urceolus and inner core, the tube chamber is arranged in the inner core, because plastics temperature in plasticizing and extrusion process can reach more than 300 ℃, pressure reaches more than the 55MPa, the material of barrel must have higher intensity, tough and tensile and corrosion-resistant, usually urceolus be by ordinary steel make, inner core is to be made by steel alloy, can remove and change after the inner core wearing and tearing; The tube chamber wall of described inner core is provided with several longitudinal grooves, theory and practice according to extrusion proves, the tube chamber wall of inner core is provided with several longitudinal grooves can make the tangent direction friction coefficient of interior tube inner surface increase, and material is melt and dissolved fully, improves the conveying capacity of plastics.
The utility model is compared with the barrel of unslotted, have characteristics such as sensitiveness that transfer rate height, extrusion capacity change head pressure is little, utilize the utility model to produce plastic product, do not need too high head pressure and forming temperature, but can obtain colory goods, and improved the quantum of output of extrusion molding in the unit interval greatly, improved production efficiency and economic benefit.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the structural representation of the utility model embodiment two.
Fig. 3 is the structural representation of the utility model embodiment three.
Label among the figure is: 1, urceolus; 2, inner core; 3, groove; 4, tube chamber.
The specific embodiment:
Below in conjunction with drawings and Examples, the utility model is described in further detail, but is not constituted any restriction of the present utility model:
Embodiment one:
As shown in Figure 1, the cylindrical shell of double-deck fluting barrel comprises the urceolus 1 of steel and the inner core 2 of alloy steel, described tube chamber 4 is arranged in the inner core 2, the wall in the tube chamber 4 of described inner core 2 is provided with 8 rectangle longitudinal grooves 3, described urceolus 1, inner core 2 cooperatively interact, to guarantee that the heat conduction is unaffected on the whole barrel wall, guarantee again to split out easily.
Embodiment two:
As shown in Figure 2, described groove be shaped as triangle, surplus with embodiment one.
Embodiment three:
As shown in Figure 3, being shaped as of described groove is trapezoidal, and be surplus with embodiment one.
The foregoing description is just for the ease of understanding the technical solution of the utility model; do not constitute restriction to the utility model protection domain; every interior any simple modification, equivalent variations and modification of perhaps according to technical spirit of the present utility model above scheme being done that does not break away from technical solutions of the utility model all still belongs within the utility model protection domain.
