The fixed seat 1 is fastened at the discharge port of the screw extruder through a bolt, and the fixed seat 1 is provided with a feed hole 11 which is butted with the discharge port of the screw extruder; the fixed seat 1 is provided with a chute 12 which is vertical to the axial direction of the screw extruder, and the carrier 2 is provided with a sliding block which is connected in the chute 12 in a sliding way.
One end of the fixing seat 1 is fixedly connected with a bracket 18, the driving mechanism is fixedly connected to the bracket 18, in the embodiment, the driving mechanism adopts a hydraulic cylinder 6, and the end part of a piston rod of the hydraulic cylinder 6 is fixedly connected to one end of the carrier 2 and drives the carrier 2 to reciprocate along the sliding groove 12.
In this embodiment, the carrier 2 has a first through hole 21 and a second through hole 22, and of course, the number of the second through holes 22 may be two or more, which is customized according to the requirement. A filter screen and a perforated plate 4 are arranged on the feed end of each second through hole 22 in sequence along the feed direction, and in order to enable the perforated plate 4 to be mounted in the second through holes 22 in a reliable manner, the inner side walls of the second through holes 22 are provided with annular shoulders 23 which are propped against the perforated plate, the filter screen is covered on the inlet end of the perforated plate 4, and the filter screen is glued on the perforated plate 4 by using melt.
The first through hole 21 does not have any other object therein.
When the carrier 2 is driven by the hydraulic cylinder 18 to move for a limited displacement, only one of the first through hole 21 or the second through hole 22 is in butt joint with the feeding hole 11 to realize material communication.
The carrier 2 is fixedly connected with a discharge part 3 covering the discharge end of the whole second through hole 22 by bolts, the discharge part 3 is provided with a plurality of discharge holes 31 communicated with the second through hole 22, the discharge holes 31 are arranged in a row, for more convenient discharge and uniformity of discharge, the inlet section of the discharge hole 31 is in a front-large and rear-small shrinkage mouth shape, the outlet section of the discharge hole 31 is in a straight cylinder shape obliquely downwards, and strip-shaped plastic which is convenient to extrude is easier to separate from the discharge hole 31 under the gravity and the front traction force.
In this embodiment, the diameters of the first through hole 21 and the feeding hole 11 are both larger than the outer diameter of the screw in the screw extruder, so that when the first through hole 21 is in butt joint with the feeding hole 11, the screw can pass through the first through hole 21 and the feeding hole 11; therefore, the installation and the disassembly of the screw rod are realized, and the whole screen changer does not need to be disassembled.
In this embodiment, in order to make the feeding and discharging more uniform, the second through hole 22 is in a reduced shape, the caliber of which is gradually reduced along the advancing direction of the material, the feeding hole 11 is in a flared shape, the caliber of which is gradually enlarged along the advancing direction of the material, the feeding hole in front of the inlet end of the porous plate 4 forms a feeding buffer cavity, and the second through hole behind the outlet end of the porous plate 4 forms a discharging buffer cavity. The melt firstly enters the feeding buffer cavity to ensure that the melt uniformly passes through the filter screen and the porous plate 4, then enters the discharging buffer cavity to ensure that the melt uniformly enters all the discharging holes, and the strip-shaped plastic extruded from the discharging holes is full of the plastic without shortage.
The side wall where the outlet end of the feeding hole 11 is located is defined as a first side wall 19, the side wall where the carrier 2 is slidably connected with the first side wall 19 is defined as a second side wall 24, and tight sliding sealing must be achieved between the first side wall 19 and the second side wall 24, so that the chute 12 on the fixing seat 1 needs to provide a pressure for the carrier 2 to force the second side wall 24 to cling to the first side wall 19, but a certain gap is necessarily provided between the carrier 2 and the chute 12 due to the limitation of assembly and processing cost, therefore, in the embodiment, a mounting groove 13 is arranged on one side wall (i.e. a third side wall) of the chute 12 of the fixing seat, a copper bar 15 is movably connected in the mounting groove 13, and the moving direction of the copper bar 15 is perpendicular to the moving direction of the carrier 2; in order to prevent the copper bar 15 from separating from the mounting groove 13, two ends of the mounting groove 13 are fixedly connected with a stop block 17 through bolts, and the stop block 17 is not contacted with the carrier; in order to force the copper bar 15 to keep contact with the carrier 2 and provide pressure to the second side wall 24, the second side wall 24 is tightly attached to the first side wall 19, a plurality of adjusting bolts 16 (the adjusting bolts are used as pushing mechanisms for pushing the copper bar 15 to move) are screwed on the third side wall, the adjusting bolts 16 are propped against the copper bar 15, one side wall of the copper bar 15 protrudes out of the mounting groove 13 and is propped against the sliding block of the carrier 2, the copper bar 15 is tightly contacted with the sliding block, and the sliding connection between the sliding block and the copper bar 15 is realized by utilizing the low friction of the copper bar 15 when the pressure is provided.
The copper bar realizes the effect of compressing the carrier, realizes the sealing connection between the carrier and the fixed seat, realizes the sliding connection between the carrier and the fixed seat by utilizing the characteristic of low friction resistance and high wear resistance of the copper bar, and reduces the wear between the carrier and the fixed seat.
In this embodiment, the fixing base 1, the carrier 2 and the discharging portion 3 are provided with at least one heating hole 5 for installing an electrothermal tube. The electric heating tube is used to keep the contact part with the melt at enough temperature to avoid the solidification of the melt.
In this embodiment, the holder 1 is provided with a sensor 14 for detecting the melt pressure in the feed hole. When the pressure in the feed hole 11 changes, the filter screen needs to be replaced.
The present invention is not limited to the above embodiments, but is capable of modification and variation in detail, and other modifications and variations can be made by those skilled in the art without departing from the scope of the present invention.
