Abstract

The utility model relates to a plastic wire drawing machine and is essentially characterized in that an air outlet (4) is arranged on a charging barrel (5) which has more than two sections connecting with each other, wherein the pitch of the screw rod in a first section charging barrel (2) is different from the pitch of the following sections, when drawing wires, the utility model needs no plastic agitator to mix and is capable of absorbing water generated from the agitation of plastic with high working efficiency and low energy loss, and the drawn plastic wires have uniform thickness, smooth surface, and uneasy stubble. The non-baking, gas exhausting, energy saving plastic wire drawing machine which is made according to the subject design of the utility model is sure to bring active using effect to the plastic processing industry.

Description

Exempt to dry by the fire exhaust energy-saving plastic wire drawing machine

The utility model relates to a kind of improvement invention of plastic-wire drawing machine, and what be specifically related to is a kind of invention of exempting to dry by the fire the energy-conservation plastic-wire drawing machine of exhaust.

In the prior art, most of plastic-wire drawing machine is when producing, plastic raw materials all will stir through plastic mixer, behind the moisture in the evaporation drying material, carry out wire drawing again, this plastic-wire drawing machine power consumption is bigger, and workshop is caused more serious pollution, when mixing time is long, produce high temperature, burn out motor easily, when mixing time was too short, the moisture in its raw material can not evaporate fully, cause the plastics silk aperture to occur, rough or fracture of wire phenomenon appears in the plastics silk of pulling out, in case when the screen pack impurity in the threeway is too much, will interrupt the threeway screw, occur flaw on the die head, its operating efficiency is not high.

In view of the problem that known technology exists, the purpose of this utility model aims to provide a kind of little power consumption, pollutes gently, and water evaporates is complete, and the plastics mercerising that is drawn is sliding, thickness is even, and high efficiency, be difficult for fracture of wire exempt to dry by the fire exhaust energy-saving plastic wire drawing machine.

For achieving the above object, the utility model is finished as follows: this is exempted to dry by the fire exhaust energy-saving plastic wire drawing machine and includes body, motor, threeway, screw rod, die head and barrel; Described motor is installed on the body; Described body is provided with reduction box; Main shaft in described screw rod and the reduction box is connected; And outside described barrel, be provided with electric calorifie installation; It is characterized in that being with at least on the screw rod barrel that is connected more than two joints; And on described barrel, be provided with exhaust outlet; The pitch of the screw rod in the described first segment barrel is with soon the pitch of the screw rod in the barrel when adjoining is different with exhaust outlet thereafter; The stem of the described second joint barrel changes pitch during at 110 millimeters from the distance of exhaust outlet; And the screw rod in the first segment barrel is identical with screw rod helical pitch in the barrel thereafter; Its pitch be in the first segment barrel screw pitch 1/2nd.

The utility model is compared with known technology, has scientific structure, and it is low to consume energy, and pollutes fewly, and institute draws that the plastics mercerising is sliding, thickness is even and advantage such as operating efficiency height, and it produces the electric energy that product per ton can be saved 140 degree, and energy-saving effect is remarkable; According to the screw cylinder structure of exempting to dry by the fire exhaust energy-saving plastic wire drawing machine of the utility model design motif made, bring positive result of use will for the plastic processing industry.

The utility model has following accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Accompanying drawing has been represented structure of the present utility model and embodiment, describe the relevant details and the operation principle of embodiment below more in conjunction with the accompanying drawings in detail, this is exempted to dry by the fire exhaust energy-saving plastic wire drawing machine and includes body 7, motor 10, threeway 8, screw rod 3, die head 9 and barrel, described motor 10 is installed on the body 7, described body 7 is provided with reduction box 11, main shaft in described screw rod 3 and the reduction box 11 is connected, and outside barrel, be provided with the electric calorifie installation (not shown), be with the barrel that is connected more than at least two joints on the described screw rod 3, present embodiment adopts three joint barrels to be connected, on its first segment barrel 2, be provided with charging aperture 1, on the second joint barrel 5, be provided with exhaust outlet 4, threeway 8 is connected an end of the 3rd joint barrel 6, the pitch of screw rod is different in the barrel when stem of the screw rod in the pitch of the screw rod 3 in the described first segment barrel 2 and the second joint barrel 5 and exhaust outlet 4 are adjoining, second save barrel 5 in the present embodiment, the pitch of screw rod is identical with its helical pitch of pitch of screw rod in the first segment barrel in the 3rd joint barrel 6, in the distance of stem and the exhaust outlet 4 of second joint barrel change pitch during at 110 millimeters, this pitch be in the first segment barrel pitch 1/2nd, it mainly acts on is to produce the backhaul phenomenon for the plastics after preventing to melt; During the utility model work, start switch, motor 10 is by the belt pulley on the belt pulley transmission reduction box 11, driving screw rod 3 after its rotating speed slows down through reduction box 11 rotates, put into the plastic pellet that will process this moment from charging aperture 1, because the gearing of screw rod 3, plastics are imported into the first segment barrel 2 from charging aperture 1, because the effect of the outer electric calorifie installation of barrel, plastics are heated, be pushed into after the fusing in the second joint barrel 5, this moment with the vavuum pump (not shown) after exhaust outlet 4 places sop up whole moisture in the molten plastic, continuation is pushed into plastics in the 3rd joint barrel 6 carries out homogenizing, plasticizing enters die head 9 and is shaped after threeway 8 is filtered, the screen pack impurity in threeway 8 is too much, when resistance is excessive, plastics can directly be discharged from described exhaust outlet 4, thus can not interrupt the threeway screw, thus make the plastics silk thickness of pulling out even, enter water tank cooling, simultaneously that is finished its whole courses of work.
