When the device is used, molten plastic is poured into the box body 1, the motor 25 is operated, the motor 25 drives the half gear 26 to rotate, when the half gear 26 is meshed with the first rotating gear 27, the half gear 26 drives the first rotating gear 27 to rotate, the first rotating gear 27 drives the screw rod 2 to rotate, the screw rod 2 drives the movable rod 3 to move, the movable rod 3 drives the press rod 5 to move, the press rod 5 drives the press plate 6 to move, so that the molten plastic in the box body 1 is extruded out through a round hole at the bottom of the box body 1, strip-shaped plastic is formed, the movable rod 3 moves to drive the positioning component on the movable rod 3 to move, so that the positioning balls 9 move in each positioning groove, when the half gear 26 is not meshed with the first rotating gear 27, the screw rod 2 stops rotating, at the moment, the second spring 10 is in a deformation state, the restoring force of the second spring 10 generates outward thrust on the push plate 8, the push plate 8 generates outward thrust on the positioning balls 9, so that the positioning ball 9 is clamped in the existing positioning groove, thereby fixing the positioning ball 9, thereby fixing the moving rod 3, at this time, the first spring 4 is in a deformation state, the restoring force of the first spring 4 generates a reverse pulling force to the moving rod 3, and at this time, the restoring force of the first spring 4 is smaller than the sum of the restoring forces of the second springs 10, thereby making the first spring 4 unable to pull the moving rod 3 to move, along with the continuous rotation of the screw rod 2, the screw rod 2 drives the moving rod 3 to continue to move downwards, when the moving rod 3 moves to a certain distance, the restoring force of the first spring 4 is larger than the restoring force of the second springs 10, thereby making the first spring 4 pull the moving rod 3 to rapidly move backwards, thereby making the moving rod 3 move to the top of the supporting rod 30, thereby preparing for the next stamping, wherein the moving distance of the moving rod 3 is not larger than the length of the box body 1, so that the pressing plate 6 can not collide with the box body 1, wherein the pushing plate 8 moves to drive the rack 13 connected with the pushing plate to move, the rack 13 drives the gear 12 meshed with the rack to rotate, the gear 12 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the other gear 12 to rotate, the other gear 12 drives the other rack 13 to move, the other rack 13 drives the other pushing plate 8 to move, the other pushing plate 8 drives the other positioning ball 9 to move, so that the two positioning balls 9 simultaneously move out of the positioning groove, thereby avoiding the situation that two sides of the moving rod 3 are deviated to cause the clamping of the moving rod 3, thereby improving the stability of the device, when the half gear 26 is meshed with the second rotating gear 28, the half gear 26 drives the second rotating gear 28 to rotate, the second rotating gear 28 drives the rotating shaft 14 to rotate, the rotating shaft 14 drives the rotating rod 15 to rotate, and the rotating rod 15 drives the fixing block 16 to rotate, fixed block 16 drive fixed block 16 is rotatory, fixed block 16 drive coupling assembling is rotatory, coupling assembling drive fixture block 17 is rotatory, fixture block 17 drive blade 18 is rotatory, thereby make blade 18 cut the strip plastics that extrude, thereby form plastic granules, here through first bull gear 27 of half-gear 26 drive and the 28 intermittent type of second bull gear operation, thereby make extrusion mechanism and cutting mechanism intermittent type operation, thereby realize plastic granules's batch production, the manpower has been saved, the efficiency is improved.

When the blade 18 needs to be installed, the locking block 20 is pulled, the locking block 20 drives the locking rod 19 to move, the locking rod 19 moves out of the groove, so that a sufficient space is reserved in the groove, then the fixture block 17 is clamped into the groove, so that the locking groove is opposite to the locking rod 19, at the moment, the third spring 21 is in a deformation state, the restoring force of the third spring 21 generates reverse pulling force on the locking block 20, the locking block 20 generates reverse pulling force on the locking rod 19, so that the locking rod 19 is clamped into the locking groove, so that the fixture block 17 is locked, the blade 18 is installed, when replacement is needed, the walking block 23 is pulled, the walking block 23 drives the pulling rope 24 to move, the pulling rope 24 drives the locking block 20 to move, so that the locking block 20 drives the locking rod 19 to move out of the locking groove, so that the locking rod 19 is in contact with the locking state of the fixture block 17, the walking block 23 is located in the walking groove, so that the walking block 23 can only move along the axial direction of the walking groove, thereby limiting the movement of the index block 23.

Compared with the prior art, this plastic granules is extrusion device in batches, through actuating mechanism drive extrusion mechanism and cutting mechanism intermittent type operation, realize plastic granules's automatic molding, compare with current extrusion device, the device has realized extrusion mechanism and cutting mechanism's operation through an output, the energy has been saved, extrusion mechanism and cutting mechanism adopt the linkage simultaneously, online cutting has been realized, and this linkage adopts pure mechanical structure, the stability and the life of device have been improved, compare with current extrusion mechanism, this mechanism avoids the carriage release lever 3 to take place the card extremely through anti-sticking unit, the stability of device has been improved, compare with current cutting mechanism, the device can realize the dismouting of blade 18 through simple push-and-pull, easy operation is convenient, the manpower has been saved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
