The beneficial effects of the utility model: steam vent is blocked by motion stops, avoid plastic material at injection, colloidal sol and penetrate the possibility of overflowing raw material in the process of moving back from steam vent, screw rod thread again on Binding protein screw rod thread turning cylinder coordinates with between dehumidifying barrel, by the possibility that dual cooperation prevents plastic material from overflowing from steam vent, to reach the effect controlling raw material and overflow, prove through test, completely the possibility producing overflow in the feed pressure dispose procedure caused because of abnormal conditions such as shutdown can be controlled to zero; Meanwhile, by the screw rod thread on band screw rod thread turning cylinder to the extruding of plastic material, further increase the discharge of the moisture in plastic material, bubble, thus ensure that plastics-production quality.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation sketch of the present utility model;
Fig. 2 is controlling party block diagram of the present utility model.
Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
A kind of injection machine as described in Figure 1 dehumidifies anti-overflow stiffening device, it comprises the dehumidifying barrel 5 that sidewall is provided with steam vent 7, rotatable band screw rod thread turning cylinder 6 is coaxially provided with in this dehumidifying barrel 5, this band screw rod thread turning cylinder 6 moves to axial the motion stops 8 that described steam vent 7 can be blocked, and this motion stops 8 is slidably matched with described dehumidifying barrel 5 and is in above the screw rod thread of described band screw rod thread turning cylinder 6.
The utility model realizes the blocking or open-minded to steam vent 7 by the lifting of motion stops 8, and when steam vent 7 is opened, the moisture in plastic material, bubble will be discharged by steam vent 7 thus, thus realizes the effect that plastic material reduces moisture, discharge bubble; When steam vent 7 blocks, plastic material can not be passed through by this steam vent 7, with the possibility preventing plastic material from overflowing from steam vent.And with the rotation of screw rod thread turning cylinder 6 in dehumidifying barrel 5, by the screw rod thread matched with dehumidifying barrel 5, the plastic material in this dehumidifying barrel 5 is extruded, bubble in plastic material is extruded further, reduces moisture to reach plastic material, discharge the effect of bubble; When being with screw rod thread turning cylinder 6 rotate or stop, this screw rod thread also can produce downward extruding force to the plastic material above gushed, and serves certain inhibitory action to plastic material gushing or overflowing.By the possibility that dual cooperation prevents plastic material from overflowing from steam vent 7, to reach the effect controlling raw material and overflow, prove through test, completely the possibility producing overflow in the feed pressure dispose procedure caused because of abnormal conditions such as shutdown can be controlled to zero.
Particularly, described dehumidifying barrel 5 is installed with connecting plate 1, this connecting plate 1 is provided with tumbler 2, the Power output of this tumbler 2 runs through this connecting plate 1 and is connected with described band screw rod thread turning cylinder 6.Control cincture screw rod thread turning cylinder 6 is carried out in the rotation dehumidified in barrel 5 and stopping by tumbler 2.
Be arranged with outside described dehumidifying barrel 5 and described motion stops 8 synchronization-moving portable plate 4 vertically, and be provided with in described dehumidifying barrel 5 can the limited step 9 of this portable plate 4 of axial location.Synchronous between this portable plate 4 with motion stops 8, mainly by being provided with at least one pair of cylinder 3 on described connecting plate 1, the cylinder rod of this cylinder 3 slides and runs through this connecting plate 1 and be connected with described portable plate 4.And be rigidly connected between portable plate 4 and described motion stops 8.Driven by the lifting of cylinder 3 pairs of portable plates 4, and then drive the lifting of motion stops 8, in order to ensure the steady lifting of portable plate 4, motion stops 8, as in the present embodiment with a pair cylinder 3 with as described in dehumidifying barrel 5 Central Symmetry arrange.
In order to ensure accurate, the punctual feeding of motion stops 8, band screw rod thread turning cylinder 6, as shown in Figure 2, this stiffening device also comprises with the injection on injection machine master control system, colloidal sol and penetrates the contactor 20 moving back signal 10 and be electrically connected mutually, and this contactor 20 is electrically connected with the control system of described tumbler 1, cylinder 3 respectively by timer 30.When contactor receive injection, the colloidal sol on injection machine master control system and penetrate move back signal 10 after will start timer 30, at this moment, the pneumatic electronic valve of control cylinder 3 and tumbler 2 all electric, by driving respectively, screw rod thread turning cylinder 6 rotates, motion stops 8 rises, and the moisture that plastic material decomposes out, gas will be discharged from steam vent 7; When the injection on injection machine master control system, colloidal sol and penetrating moves back after signal 10 disappears, the pneumatic electronic valve dead electricity of control cylinder 3 after timer 30 timing completes, portable plate 4 and motion stops 8 will decline, until be down to limited step 9 place, to reach the blocking of steam vent 7, avoid the pressure of plastic material to rush down pressure and overflow; After timer 30 timing simultaneously completes, tumbler 2 will stop operating, and at this moment, exhaust event will stop, and coordinate motion stops 8 down maneuver to carry out secondary energy-saving, enter and wait for that next action starts.
In the present embodiment, the power drive of described tumbler 1 be electronic, pneumatic or hydraulicdriven any one.
Above the technical scheme that the utility model embodiment provides is described in detail, apply specific case herein to set forth the principle of the utility model embodiment and embodiment, the explanation of above embodiment is only applicable to the principle helping to understand the utility model embodiment; Meanwhile, for one of ordinary skill in the art, according to the utility model embodiment, detailed description of the invention and range of application all will change, and in sum, this description should not be construed as restriction of the present utility model.
