Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plastic particle processing equipment, in particular to a modular splicing integrated underwater pelletizing device. BACKGROUND

[0002] The working principle of the traditional plastic pelletizer is to melt and filter the plastic through an extruder, extrude an extruded strip, and then pelletize after cooling and solidification. The underwater pelletizing extrusion pelletizer is a new type of machine that contacts with cooling water at the moment of melt extrusion die face and directly pelletizes. Since the hot melt material is cut off by the blade in the melt state and thrown into the circulating water for cooling and solidification, the underwater pelletizing extrusion pelletizer is suitable for pelletizing hot melt materials with different viscosities. Compared with the traditional strip drawing pelletizing process, the pelletizing speed is fast and the pelletizing quality is good.

[0003] After completing the underwater pelletizing, the produced TPE particles form a solid-liquid mixture with water, and the TPE particles need to be fished out of the water and dried for easy storage. The existing method for transferring and drying the underwater hot-cut TPE particles is to fish out the TPE particles by manual fishing, then drain the water through a screen, and then dry the TPE particles by natural air drying or blowing air drying. This TPE particle transfer and drying method is time-consuming and labor-intensive, has high labor cost, and is low in efficiency, which cannot meet the demand of large-scale production. SUMMARY

[0059] Operation process: the receiving box 101 is installed on the extruder outlet position through the bolt holes on the connecting retaining ring and the bolts, and the water input pipe 301 of the water conveying assembly 300 is installed on the receiving box 101, the water input pipe 301 is connected with a water tank and a water pump is installed, and the water output pipe 302 is connected to the lower end of the receiving box 101.

[0060] Then the water pump of the water conveying assembly 300 is started, the water in the water tank is pumped into the receiving box 101, and the cutting space 102 is filled with cooling water. The motor of the driving member of the cutting assembly 200 is started, the motor shaft drives the first driving gear to rotate, and the second driving gear is driven to rotate through the meshing with the first driving gear, so that the cutting block 201b rotates, and the cutting knife body 201c arranged around the cutting block 201b cuts the molten plastic extruded from the extruder below the extrusion outlet side.

[0061] When the cutting block 201b rotates, the coaxially arranged toggle plate 203d rotates synchronously, the protruding rod 203e on the toggle plate 203d contacts the clamping rod 205 on the chuck 203f in the intermittent control component 203, and drives the clamping rod 205 to move, so that the chuck 203f rotates, and in turn drives the ratchet teeth 203c on the mating contact 204 to move. During the rotation of the chuck 203f, the hinge joint 206 on the mating contact 204 drives the toggle lever 202f hinged thereto to act, and the toggle lever 202f pushes the conveying guide roller 202b to move downward. The conveying guide roller 202b moves vertically downward under the limitation of the cylindrical ring of the support 202a, compresses the telescopic spring 202g between the conveying guide roller 202b and the support 202a, and the lower end of the conveying pressure plate 202c descends.

[0062] When the conveying pressure plate 202c descends, it pushes the plastic particles on the bottom, and uses the protruding block to contact the abutment plate on the inner wall of the filter pipe 202e to drive the filter pipe 202e to move downward. At this time, the conveying pressure plate 202c presses the particles on the bottom into the filter pipe 202e together with the cooling water, and as the conveying pressure plate 202c gradually descends, the cooling water between the conveying pressure plate 202c and the filter pipe 202e is discharged from the water hole 202d on the conveying pressure plate 202c.

[0063] As the conveying pressure plate 202c gradually approaches the filter pipe 202e, the first rotating rod 303b and the second rotating rod 303c change from the state of moving away from each other to the state of moving close to each other, at which time the several closing plates 303e move close to each other to seal the lower end of the filter pipe 202e, at which time the plastic particles are completely pressed under the lower end of the conveying pressure plate 202c, and the water is guided to the position above the conveying pressure plate 202c.

[0064] When the dial 203d continues to dial the clamping rod 205 to rotate, the clamping rod 205 moves to the position below the ratchet 203b, at which time because the direction of the teeth of the ratchet 203b changes from originally upward to downward, at this time the upward force of the lower end of the dial rod 202f applied by the spring 306 directly acts on the chuck 203f, at which time the engagement between the ratchet teeth 203c on the chuck 203f and the ratchet 203b is no longer blocked, at which time the dial rod 202f will quickly rise, thereby also causing the chuck 203f to quickly rotate, in the process, the conveying pressure plate 202c is also synchronously and quickly pulled up, and the conveying pressure plate 202c synchronously drives the filter pipe 202e to move upward.

[0065] At this time, the first rotating rod 303b and the second rotating rod 303c are respectively pulled to change to the state of moving away from each other, and the first rotating rod 303b and the second rotating rod 303c move away from each other to pull the pull rod 308, which drives the rotating block to make the closing plate 303e rotate from the original horizontal state to the vertical state, at which time the passage at the lower end of the filter pipe 202e is opened, and the plastic particles fall out of the water output pipe 302 at the lower end.

[0066] Then the plastic particles fall into the distribution groove 404 of the distribution disc 403 in the receiving disc 402, the distribution disc 403 rotates, the distribution groove 404 clamps the plastic particles to move together, the plastic particles are frictionally corrected between the distribution groove 404 and the receiving disc 402, and finally are discharged from the discharge port 405 at the lower end of the receiving disc 402.

[0067] The whole operation process enables the particles to be cooled in the water body after being cut off, and realizes solid-liquid separation when being sent out, so that the plastic particles are separated from the water, and thus a subsequent filtering process is not needed, the processing steps are reduced, the downward process of the conveying pressure plate 202c is relatively slow, so that as much water as possible is filtered from the space between the conveying pressure plate 202c and the filter pipe 202e, and the upward speed of the conveying pressure plate 202c is relatively fast, so that the plastic particles between the conveying pressure plate 202c and the filter pipe 202e can quickly fall, and the structure realizes rapid solid-liquid separation and increases the production efficiency.

[0068] The entire device is integrated in the receiving box 101, and each internal component can be disassembled, realizing modular installation and facilitating subsequent maintenance.
