Abstract
The utility model discloses a plug-in additional heating wood plastic mixing extrusion machine which comprises a spiral cylinder, wherein one end of the spiral cylinder is provided with a charging hopper, the other end thereof is provided with a hot cutting machine head and a discharge port, a heating rod is arranged on the external peripheral wall of the spiral cylinder, and a propulsion screw rod is positioned in the spiral cylinder. The plug-in additional heating wood plastic mixing extrusion machine has the characteristics of fast heating and excellent heating permeability, the inventiveness of the plug-in additional heating wood plastic mixing extrusion machine is that the heating rod which directly achieves the root portion of screw thread can directly transfer heat to the inner portions of materials, thereby overcoming the defects of traditional heating mode that heat is gradually transferred to the inner side of materials as being heated from the outside of the spiral cylinder,the half-baked or carbonization phenomena of products are avoided, moreover, the fast and direct heating mode saves time, thereby a great amount of energy resources is saved.
Description
Technical field
The utility model relates to a kind of insertion compensation heated type wood and moulds mixing extruder.
Background technology
Extruder is the universal machine that wood is moulded processing, as the various floors of extrusion molding, decorative panel, ornamental strip etc., its screw form has single screw rod and twin-screw, basic principle is that high molecule plastic and various wood-fibred or string compressed mixed are processed into a kind of melt, increase pressure and make its plasticizing make particle, perhaps by various mould moldings.The shortcoming of existing extruder is that compression ratio is excessive; make machine produce serious wearing and tearing; secondly wood-fibred and string have good heat insulating ability; its thermal conductivity extreme difference; cause plastics and fiber fusion plastification fully in barrel, make particle or the product extruded produce serious half-cooked or carbonization.
The utility model content
The purpose of this utility model provides a kind of insertion compensation heated type wood and moulds mixing extruder, and is simple in structure, can under the prerequisite that does not increase compression ratio athermanous fiber fully be heated, and itself and high molecule plastic fully merged blend together a kind of new material mutually.
For achieving the above object, technical scheme provided by the utility model is: a kind of insertion compensation heated type exhaust wood is moulded mixing extruder, comprise barrel, one end of described barrel is provided with loading hopper, the other end is provided with fervent head and discharging opening, interlude is provided with exhaust outlet, is provided with heating rod on the periphery wall of barrel; Be provided with pusher screw rod in the described barrel.
Described screw rod is made as two sections: to being provided with sudden change formula single-wormed screw between the exhaust outlet, be made as gradual change type single-wormed screw from exhaust outlet to discharging opening from loading hopper.
Described sudden change formula single-wormed screw and gradual change type single-wormed screw are made as integrative-structure.
The depth of thread on described sudden change formula single-wormed screw and the gradual change type single-wormed screw all is made as from the upstream and reduces gradually downstream.
Described heating rod is made as plug-in type and stretches in the barrel.
Described heating rod is made as 3～5 districts, and every district 2～3 rows are uniform, and every row is provided with 4～10 heating rods.
The advantage that the utlity model has: the utlity model has the characteristics that heating is fast, heat good penetrability, its creativeness is: the heating rod of through thread root directly is sent to heat the inside of material, overcome traditional by the barrel externally heating, heat passes to the mode of heating of material the inside gradually, avoided the phenomenon of the half-cooked or carbonization of product, through fast commentaries on classics hot mode has been saved heat time heating time, has also just saved a large amount of energy.
The utility model is by plug-type mode of heating, shortened heat time heating time greatly, because heating rod is embedded in material inside and makes athermanous fiber increase heating surface area, overcome the half-cooked and carbonization phenomenon that product produces because of the inequality of being heated fully, improved efficient, improve the quality of product, also saved a large amount of energy simultaneously.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but content of the present utility model be not limited to for embodiment.
Fig. 1 is the utility model structural representation.
The specific embodiment:
A kind of insertion compensation heated type exhaust wood is as shown in Figure 1 moulded mixing extruder, comprise barrel 1, an end of barrel 1 is provided with loading hopper 2, and the other end is provided with fervent head 4 and discharging opening 3, interlude is provided with exhaust outlet 5, is provided with plug-in type heating rod 8 on the periphery wall of barrel 1.Be provided with pusher screw rod in the barrel 1, this screw rod is made as two sections: be provided with sudden change formula single-wormed screw 6 between 5 from loading hopper 2 to exhaust outlet, 3 are made as gradual change type single-wormed screw 7 from exhaust outlet 5 to discharging opening.
Two sections screw rods are made as integrative-structure, and the depth of thread all reduces to the downstream gradually from the upstream.
METAL HEATING PROCESS rod 8 is 3～5 districts, and every district 2～3 rows are uniform, and every row is provided with 4～10 heating rods.
The utility model product at first with the screw rod of sudden change with the compression of heating of high molecule plastic and fiber, traditional extruder has only the surface that heat is reached screw rod by the outer heater of barrel, can not be deep into the inside of material, the utility model is under the effect that is inserted to the thread root heating rod, after screw rod and material fully are heated air and moisture are got rid of barrel, material after be heated this moment enters the gradual change plasticizing zone, variation along with the gradual change screw rod, compression ratio increases, high molecule plastic and fiber are further sent up to discharging opening before the compression, be cut into granular material by fervent head then.
The above only is preferred embodiment of the present utility model, is not the utility model is done any pro forma restriction.Any those skilled in the art, all still belong in the protection domain of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
