When the injection molding machine is used, when a charging barrel inner cavity 14 in the injection molding machine is blocked, the built-in threaded shaft 30 rotates to drive the movable threaded block 44 to move downwards, and the scraping block 41 slides on the inner wall of the charging barrel inner cavity 14 on the upper side, the scraping and sweeping plate 47 is driven to swing at the moment, the U-shaped swinging rod 39 is driven to move away from or close to each other to swing, the symmetrical rod cross rod 43, the embedded built-in rotating shaft 46 and the embedded torsion spring 36 are driven to rotate, the cross rod 43 is driven to swing, the intermediate wheel 40 is driven to rotate, the embedded rotating shaft 37 is driven to rotate, the scraping block 41 and the scraping and sweeping plate 47 clean the blockage on the inner wall on the upper side of the charging barrel inner cavity 14, the movable threaded block 44 moves downwards to drive the connecting shaft 45 to move downwards, and the limiting spring 53, the rotating rod 51 and the opening swinging rod 54 are driven to rotate, The crushing rod 59 moves downwards, when the auxiliary swing rod 49 contacts the upper inner wall of the inner cavity 14 of the charging barrel, the auxiliary swing rod 49 is driven to swing, the auxiliary swing rod 49 cleans the blockage on the inner wall, the auxiliary torsion spring 50, the symmetrical wheel 55 and the symmetrical swing shaft 56 are driven to rotate, the contraction block 48 is driven to move close to each other, the return spring 61 is compressed, the opening swing rod 54 is driven to rotate on the outer peripheral surface of the rotation rod 51, the rotation rod 51 is driven to move upwards, the opening swing rod 54 rotates to drive the crushing rod 59 to rotate, the cutting strip 60 and the crushing block 58 are driven to rotate, the crushing block 58 and the cutting strip 60 perform a crushing function on the blockage in the inner cavity 14 of the charging barrel, when the residual materials in the pipeline at the lower side of the inner cavity 14 of the charging barrel need to be cleaned, the driving shaft 66 rotates at the moment, the spiral sheet 78 is driven to rotate, and the embedded threaded shaft 76 rotates, and then drive and move the screw block 80 and move close to each other, and then drive and strike off wheel 77, strike off axle 79, short support 35 and move, and then drive bracing piece 75, clearance piece 82 and move, and clearance piece 82 strikes off the processing to the clout on the pipe inner wall of feed cylinder inner chamber 14, and strikes off the processing to the clout on spiral piece 78 with scraping wheel 77.

When the problem of blockage of the charging barrel of the injection molding machine needs to be solved and surplus materials of a subsequent pipeline need to be cleaned, the driving motor 70 is started at the moment, so that the driving shaft 66 and the driving belt pulley 65 are driven to rotate, so that the vertical belt 63 is driven to rotate, so that the side belt pulley 72, the lower threaded shaft 62, the driven shaft 71, the symmetrical belt pulley 64 and the driving bevel gear 68 are driven to rotate, so that blockage prevention and surplus material cleaning in the next step are driven, when blockage occurs in the charging barrel of the injection molding machine or surplus materials need to be cleaned in the pipeline, the right rotating shaft 32 rotates, so that the right belt pulley 31, the horizontal driving belt 27, the side bevel gear 26, the vertical rotating shaft 25, the middle belt pulley 28, the middle rotating shaft 29 and the internal threaded shaft 30 rotate, the internal threaded shaft 30 further prevents blockage of the upper side of the internal cavity 14 of the charging barrel, and the, and then drive right side pivot 32 and rotate, prevent injection molding machine feed cylinder jam and clearance pipeline clout this moment, when needing to wash the clout in the feed cylinder inner chamber 14, perpendicular pivot 25 rotates this moment, and then drives perpendicular bevel gear 24, fixed bevel gear 23, horizontal threaded shaft 20 and rotates, and then drives cleaning operation on next step.

When the lower side of the inner cavity 14 of the charging barrel needs to be cleaned by excess materials and the waste liquid needs to be recovered, the cleaning liquid is filled through the communication port 17 at the upper side, the cleaning liquid is recovered through the communication port 17 at the lower side, when the remainder of the interior of the cartridge interior chamber 14 needs to be cleaned and removed, the transverse threaded shaft 20 is now rotated, thereby driving the fixed thread blocks 19 to move close to or away from each other, further driving the cleaning box 22 and the nozzle 21 to move, at this time, starting the cleaning box 22, then the cleaning liquid in the cleaning box 22 is filled into the lower side of the material cylinder inner cavity 14 through the spray pipe 21 to remove the excess materials, and after the cleaning of the waste liquid after cleaning is finished, the lower threaded shaft 62 rotates, thereby moving the lower screw block 83, the absorption pump 73 and the suction pipe 74 away from or close to each other, and at this time, the absorption pump 73 is started, the waste liquid thus cleaned is sucked into the suction pump 73 through the suction pipe 74, thereby achieving the effect of recovery.

The invention has the beneficial effects that: the automatic blockage cleaning device can automatically check whether the charging barrel of the injection molding machine is blocked during feeding so as to achieve the effect of triggering the blockage cleaning, so that the injection molding machine can be more efficient during feeding and the damage of the injection molding machine caused by the blockage of the charging barrel can be prevented, and after the injection molding machine is machined, excess materials adhered to an inner pipeline can be quickly cleaned so as to ensure that the next machining and manufacturing can not be influenced.
