Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of extrusion die heads of extrusion machines, and particularly relates to a cleaning device for extrusion die heads of extrusion machines. Background Art

[0002] An extrusion machine is an important plastic machine, and the production and manufacturing of most plastic products can be achieved by extrusion molding. The extrusion machine motor is an important component of the extrusion machine and is the prime mover of the extrusion machine, providing the large thrust required by the extrusion machine screw.

[0003] Currently, when a traditional extrusion machine is in use, first, the staff injects the mixed raw materials into the extrusion machine. Then, the raw materials are melted at high temperature inside the extrusion machine, and the melted raw material slurry will move towards the extrusion die head under the action of the extrusion screw, so as to discharge the slurry from the holes on the extrusion die head, and thus obtain particle strips with the required diameter, which is convenient for subsequent cooling and cutting.

[0004] Since, when the above-mentioned extrusion machine stops being used, due to the too high temperature of the extrusion die head, in order to avoid scalding, the staff can only use a shovel to shovel off the last extruded part of the glue liquid of the extrusion die head, and the glue liquid inside the holes of the extrusion die head and the inner cavity of the extrusion die head will be processed after being completely cooled. When processing, the staff first disassembles it, and then uses an electric drill in cooperation with a cleaning brush and a drill bit to start processing the holes and the inner cavity of the extrusion die head. This cleaning method not only wastes time, but also increases the labor of the staff, and finally reduces the production efficiency. Summary of the Utility Model

[0046] The working principle and usage process of the present utility model:

[0047] In the use state:

[0048] In use, first, open the cabinet door 8. Then, bring the circumferential surface of the extrusion die head 4 into contact with one side of the arc-shaped positioning groove 53. After contact, rotate the clamping screw rod 32. When the clamping screw rod 32 rotates, it will cooperate with the square rod 35 to drive the clamping block 33 to move forward. With the cooperation of the two clamping blocks 33, the extrusion die head 4 can be fixed in the arc-shaped clamping groove 34. After clamping, start the forward-pushing hydraulic rod 61. When the forward-pushing hydraulic rod 61 works, it will drive the slicing knife 62 to move forward. As the slicing knife 62 moves, the glue adhered to the top surface of the extrusion die head 4 can be removed, and after removal, the holes on the extrusion die head 4 can be exposed. When the forward-pushing hydraulic rod 61 works, the rotating motor 22 and the lifting hydraulic rod 27 also work. As the rotating motor 22 works, it will drive the hollow sleeve 23 to rotate through the gear set. When the hollow sleeve 23 rotates, it will cooperate with the sliding block 24 and the arc-shaped groove 210 to drive the cutting shaft 29 to rotate. When the cutting shaft 29 rotates, it will drive the cutting knife 211 to rotate. When the cutting knife 211 rotates, the lifting hydraulic rod 27 will drive the cutting shaft 29 to move upward, thus driving the cutting knife 211 to move upward. At this time, the inner cavity of the extrusion die head 4 is cleaned by the cutting knife 211. During cleaning, the hollow sleeve 23 will also drive the cleaning rod 25 to rotate, so as to clean the glue on the top surface of the mounting cover 21 through the cleaning rod 25. When the cleaning rod 25 works, it will also drive the L-shaped rod 26 to rotate, so as to clean the glue around the mounting cover 21 to both sides of the inner cavity of the cleaning box 1;

[0049] After the cutting knife 211 is reset, start the lifting pneumatic rod 71 and the cleaning motor 76. When the cleaning motor 76 works, it will drive one of the drill rods 74 to rotate. When one of the drill rods 74 rotates, it will drive the other drill rods 74 to rotate under the action of the gear. As the lifting hydraulic rod 71 works, it will drive the U-shaped frame 72 and the drill rods 74 to move downward, so as to start cleaning the holes on the extrusion die head 4 through the drill rods 74. After cleaning, at this time, the cleaning brush 75 enters the holes and starts to clean the inner wall of the holes again, and the cleaning of the extrusion die head can be completed.
