The specific embodiment
Below by specific embodiment the filter in the breathing mask production line of the present invention is described in further detail.
As shown in Figure 1 and Figure 2, filter in the breathing mask production line, comprise the fixed block 3 that is arranged between screw extruder discharge end 1 and the die head feeding end 2, being provided with in the described fixed block 3 can be along the movable block 4 of vertical activity, the upper end of movable block 4 is provided with upper limit position block 13, the lower end of movable block 4 is provided with lower position block 14, movable block 4 is driven by drive unit, described drive unit comprises oil cylinder 5, the motion bar of oil cylinder 5 is connected with movable block 4 by upper limit position block 13, and the cylinder body of oil cylinder 5 is connected with fixed block 3 by support 6.Be provided with two filter blocks in the movable block 4, be last filter block 7 and following filter block 8, two filter blocks are along vertical array, all be densely covered with filtering holes 9 in the every filter block, the front end of every filter block is respectively arranged with screen pack, be last screen pack 10 and following screen pack 11, the discharge end 1 of described screw extruder is provided with pressure sensor 12, pressure sensor 12 is connected with the communication of PLC controller, described oil cylinder 5 is connected with the communication of PLC controller, described support 6 upper ends are provided with near switch 15, and fixed block 3 lower ends are provided with down near switch 16, go up near switch 15 all to be connected with the communication of PLC controller near switch 16 with following.As everyone knows, above-mentioned drive unit can wait with cylinder, linear electric motors fully and replace, and all belongs to invention which is intended to be protected.
Operation principle of the present invention is: the PVC material enters filter after screw rod is extruded, and be subjected to the filtration of screen pack when the screen pack and remove impurity, and then through entering die head after the filtering holes in the filter block.As shown in Figure 2, this at present filter block 8 be in the operating position, when the impurity that gathers on the screen pack 11 acquires a certain degree instantly, the material of extruding from screw extruder can be deposited in the discharge end 1 of screw extruder, pressure in the screw extruder barrel is increased, when pressure increases to a certain degree, pressure sensor 12 transfers to the PLC controller with pressure signal, 5 actions of PLC controller control oil cylinder, the motion bar of oil cylinder 5 stretches out, thereby driving movable block 4 moves down, after movable block 4 moves to assigned address, can send signal near switch 14 down and give the PLC controller, add that upper limit position block 13 cooperates, make filter block 7 move to the operating position, thereby avoided the not in place or motion of movable block 4 motion to exceed assigned address and cause and gather materials, and filter block 8 is in off-position and is positioned at the outside of fixed block 3 down, thereby can change down screen pack 11; When positive impurity acquires a certain degree on the last screen pack 10, the material of extruding from screw extruder can be deposited in the discharge end 1 of screw extruder, pressure in the screw extruder barrel is increased, when pressure increases to a certain degree, pressure sensor 12 transfers to the PLC controller with pressure signal, 5 actions of PLC controller control oil cylinder, the motion bar withdrawal of oil cylinder 5, thereby driving movable block 4 moves up, after movable block 4 moves to assigned address, go up and to send signal to the PLC controller near switch 15, add the cooperation of locating piece 14 up and down, make down filter block 8 move to the operating position, and go up the outside that filter block 7 is in off-position and is positioned at fixed block 3, thereby can replace with screen pack 10.
The invention has the beneficial effects as follows: the filter in the above-mentioned breathing mask production line, simple in structure, with low cost, easy to use, the maintenance easy.It need not to dismantle fixed block 3 and just can realize changing screen pack, compares with present employed filter, has improved production efficiency greatly.And the detection by pressure sensor 12, control the draping time by the PLC controller, realized automatic control, avoided causing impurity to enter the generation of die head situation because draping is untimely, further improved production efficiency.
The above embodiments are the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the present invention; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
