Description

Technical Field

[0002] Granulation equipment is a molding machine that can manufacture materials into specific shapes. It is generally divided into: dry roller granulators, rotary drum granulators, and dry roller press granulators. However, we have found the following shortcomings in the existing modified polypropylene pelletizing equipment during the pelletizing process: the driving of the pelletizing blade and the driving of the feeding are two independent power parts, which cannot further improve the synchronization of pelletizing and feeding, resulting in a decrease in the uniformity of pelletizing quality. Utility Model Content

A group of the pelletizing blades are distributed and installed on the annular surface of a turntable, and the middle part of the turntable is assembled with one end of the transmission rod. The turntable is set in a front circular groove. Guide tubes are distributed around the drive column located on one side of the middle part of the transmission rod, and a spiral rubber strip is provided on the surface of the drive column. Each guide tube has a strip-shaped hole on its surface, and a portion of the spiral rubber strip extends into the strip-shaped hole. The other end of the transmission rod is connected to the shaft end of the motor.

[0005] Preferably, one end of the conduit is connected to the port of the anterior column hole, and the other end of the conduit is connected to the port of the posterior column hole.

[0006] Preferably, the front pillar holes are provided in a plurality of manner, and the plurality of front pillar holes are arranged in a ring on the front pillar, and the other end of the front pillar holes is connected to the interior of the front circular groove located at one end of the front pillar.

[0019] Please see Figure 1-3 As shown, a modified polypropylene pelletizing device includes pelletizing blades 2, a transmission rod 3, a guide tube 5, a drive column 6, a spiral rubber strip 610, and a motor 8. A group of pelletizing blades 2 are distributed and installed on the annular surface of a turntable 1, and the middle part of the turntable 1 is assembled with one end of the transmission rod 3. The turntable 1 is set in a front circular groove 410. The guide tubes 5 are distributed around the drive column 6 located on one side of the middle part of the transmission rod 3, and the surface of the drive column 6 is provided with a spiral rubber strip 610. Each guide tube 5 has a strip-shaped hole 510 on its surface, and a portion of the spiral rubber strip 610 extends into the strip-shaped hole 510. The other end of the transmission rod 3 is connected to the shaft end of the motor 8.

[0020] One end of the conduit 5 is connected to one end of the front post hole 420, and the other end of the conduit 5 is connected to one end of the rear post hole 710. The conduit 5, the front post hole 420 and the rear post hole 710 are interconnected so that the modified polypropylene filament can be inserted.

[0021] The front post hole 420 is provided in multiple ways, and the multiple front post holes 420 are arranged in a ring on the front post 4. The other end of the front post hole 420 is connected to the inside of the front circular groove 410 located at one end of the front post 4. The middle part of the front post 4 is rotatably connected to the corresponding part of the transmission rod 3 through the bearing. Through the multiple front post holes 420, it is convenient for the ends of multiple modified polypropylene wires to enter the pelletizing blade 2.

[0022] The rear column hole 710 is provided in multiple ways, and the multiple rear column holes 710 are arranged in a ring on the rear column 7. The middle part of the rear column 7 is rotatably connected to one end of the transmission rod 3 through a bearing, and the rear circular groove 720 located at the corresponding end face of the rear column 7 is fixedly connected to the motor 8.

[0023] Working principle: First, multiple modified polypropylene strips are passed through the rear column hole 710, the guide tube 5 and the front column hole 420 in sequence, so that the ends of the modified polypropylene strips are located at the pelletizing blade 2. Then, the motor 8 drives the transmission rod 3 to rotate, so that the drive column 6, the turntable 1 and the pelletizing blade 2 located on the turntable 1 are all in a rotating state. At this time, the rotating pelletizing blade 2 performs pelleting, and the spiral rubber strip 610 located on the drive column 6 rotates to drive the modified polypropylene strips located inside the guide tube 5 to move forward.

[0024] Compared with existing technologies, the difference lies in the fact that the same power structure is used to drive the spiral rubber strip 610 located in the drive column 6 to rotate. Combined with the fact that part of the spiral rubber strip 610 extends into the strip hole 510 and makes frictional contact with the modified polypropylene line, the function of driving the modified polypropylene line to move and feed material to the cutting position is realized. This greatly simplifies the structure of the pelletizing equipment. In addition, the contact area between the spiral rubber strip 610 and the modified polypropylene line is long, which ensures the effectiveness and continuity of driving the modified polypropylene line, and the synchronization of cutting and feeding is high.
