Description
Technical Field
The utility model relates to an extruder technical field, especially the filter of convenient renew cartridge for the extruder.
Background
In the process of plastic extrusion, after long-time plasticization and heating of plastic melt, decomposition residues can be generated in the melt, and impurities in raw materials enter an extruder head, so that a flow channel can be blocked, and plastic products have defects and even can not be normally produced: in order to filter impurities, a filter screen is usually arranged between the head of the screw and an extrusion molding machine head to prevent the impurities and the impurities from entering the molding machine head and continuing the extrusion time, the impurities on the filter screen are gradually accumulated to cause the pressure rise of the machine head and the flow rate reduction, and when a certain filter screen is exceeded, the filter screen is broken, and the filter screen fails, the filter screen must be replaced; the whole operation process is dozens of minutes less and hours more from the die head removal, the cleaning, the filter screen replacement, the temperature rise again and the blank traction to the normal production extrusion, which causes the raw material loss, the energy waste and the production cost increase.
SUMMERY OF THE UTILITY MODEL
To the above situation, for overcoming prior art's defect, the utility model provides an extruder is with convenient renew cartridge's filter, the effectual filter screen of having solved current extruder need shut down always when changing, extravagant plenty of time, causes the problem that raw and other materials loss, the energy is extravagant, manufacturing cost increase.
The technical scheme includes that the device comprises a horizontal cylindrical shell, the left end of the shell is in an open shape, a rotatable cylindrical block is placed in the shell, a cavity is formed in the cylindrical block, a plurality of through holes are uniformly distributed in the periphery of the cavity in a circumferential manner, a filter screen is fixed at the outer end of each through hole through a plurality of screws, an annular plate which can slide left and right and is coaxial with the through holes is arranged in each through hole, a baffle is arranged on one side, close to the cavity, of each annular plate, the baffle is connected with the annular plate through a plurality of springs, and when the baffle is tightly attached to the annular plate, the through holes are; the right end of the shell is provided with a horizontal feeding barrel, the lower end of the cylindrical block is fixed with a vertical discharging barrel, and the lower section of the discharging barrel penetrates through the side wall of the shell and is arranged below the shell.
The utility model discloses the structure is ingenious, can realize not shutting down and change the filter screen, and the dead time that significantly reduces can effectively reduce the time that changes the filter screen and consume, is favorable to improving the productivity.

Detailed Description
The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a horizontal cylindrical casing 1, the left end of the casing 1 is open, a rotatable cylindrical block 2 is placed in the casing 1, a cavity 3 is formed in the cylindrical block 2, a plurality of through holes 4 are uniformly distributed on the periphery of the cavity 3, a filter screen 5 is fixed at the outer end of each through hole 4 through a plurality of screws, a ring-shaped plate 6 which can slide left and right and is coaxial with the through hole 4 is arranged in the through hole 4, a baffle 7 is arranged on one side of the ring-shaped plate 6 close to the cavity 3, the baffle 7 is connected with the ring-shaped plate 6 through a plurality of springs, and the through hole 4 is blocked when the baffle 7 is tightly attached to the ring-shaped plate 6; the right end of the shell 1 is provided with a horizontal feeding barrel 8, the lower end of the cylindrical block 2 is fixed with a vertical discharging barrel 9, and the lower section of the discharging barrel 9 penetrates through the side wall of the shell 1 and is arranged below the shell 1.
In order to limit the annular plate 6 and prevent the annular plate 6 from being separated from the through hole 4, annular protrusions are arranged on the side walls of two ends of the through hole 4.
In order to realize the rotation and the fixation of the cylindrical block 2, the upper end of the cylindrical block 2 is rotatably connected with a side plate of the shell 1, a disc 10 is arranged above the shell 1, a plurality of positioning holes which correspond to the through holes 4 one by one are formed in the disc 10, pins 11 are inserted into the positioning holes, a rectangular block 12 is fixed on the upper end surface of the shell 1, a clamping hole is formed in the rectangular block 12, and the lower end of each pin 11 is arranged in the clamping hole.
When being worth noting, a bearing is arranged between the discharging barrel 9 and the shell 1, a sealing ring is arranged between the outer edge surface of the annular plate 6 and the side wall of the through hole 4, and a sealing ring is arranged between the cylindrical block 2 and the inner side wall of the shell 1.
When the extruder is used, materials of the extruder enter from the feeding cylinder 8 on the right side of the shell 1, the materials enter the through hole 4 on the right side through the filter screen 5, the annular plate 6 in the through hole 4 moves leftwards, the baffle 7 on the annular plate is separated from the annular plate 6 under the action of pressure, the materials smoothly enter the cavity 3, the annular plates 6 in the rest through holes 4 and the corresponding baffle 7 are mutually clung together under the action of pressure, and the through hole 4 where the annular plates are located is blocked, so the materials can only be discharged through the discharging cylinder 9 on the lower section of the cavity 3; after a period of time, filter screen 5 need be changed or the clearance, pulls out pin 11 this moment upwards, rotates disc 10, and disc 10 drives cylinder piece 2 and rotates for next filter screen 5 rotates the position of feed cylinder 8, has realized filter screen 5's change.
The utility model discloses the structure is ingenious, can realize not shutting down and change filter screen 5, and the dead time that significantly reduces can effectively reduce the time of changing filter screen 5 and expend, is favorable to improving the productivity.
