Utility model content

The technical problem to be solved by the utility model is to provide a plastic granulation mechanism to solve the problem that the cooling and cutting of the traditional plastic after extrusion is completed in two processes, which not only increases the cost, but also has low work efficiency.

In order to solve the above technical problems, the technical solution of the utility model is: a plastic granulation mechanism, including a screw extruder, a water tank, a motor, a crankshaft, a backing plate, a cutter holder, a cutter, a spring, and the water tank Located at the left end of the screw extruder, the water tank is threadedly connected with the screw extruder, the motor is located on the back of the water tank, the motor is threaded with the water tank, the crankshaft runs through the upper end of the water tank, and the crankshaft is connected to the The water tank is rotatably connected, and the crankshaft is closely connected with the motor, the backing plate is located inside the water tank, the backing plate is connected with the water tank thread, the cutter fixing seat runs through the crankshaft, and the cutter The fixed seat is closely connected with the crankshaft, the cutter is located at the bottom of the fixed seat, the cutter is connected with the fixed seat by sliding, and the spring is located between the cutter and the fixed seat and the cutter.

Further, the bottom of the water tank is also provided with a discharge hole.

Further, a recycling box is provided at the bottom of the water tank, and the recycling box is threadedly connected with the water tank.

Further, the upper end of the recovery box is also provided with a filter screen, and the filter screen is threadedly connected with the recovery box.

Further, a material storage box is also provided on the back of the recovery box, and the material storage box is threadedly connected with the recovery box.

Further, a water pump is provided at the bottom of the water tank, the water pump is connected to the water tank by threads, and the water pump is connected to the recovery tank pipeline.

Compared with the prior art, the plastic granulation mechanism first extrudes the plastic into long strips through the screw extruder, and discharges it into the water tank, cools the plastic through the water in the water tank, and then drives the crankshaft to rotate by the motor. So as to drive the cutter to rotate up and down. When the cutter rotates to the lower end and contacts the plastic, the plastic cutting process is completed under the joint action of the backing plate, so the plastic granulation process is completed. The structure of the mechanism is simple and the design is reasonable. Plastic cooling and cutting and granulation are completed at one time, instead of the traditional two-step process, which not only reduces costs, but also improves production efficiency.

The following specific embodiments will be further described in conjunction with the above-mentioned drawings.

detailed description

In the following, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art that the described embodiments may be practiced without some or all of these specific details. In other instances, well known processing steps have not been described in detail.

As shown in Figure 1, Figure 2, Figure 3, and Figure 4, a plastic granulation mechanism includes a screw extruder 1, a water tank 2, a motor 3, a crankshaft 4, a backing plate 5, a cutter holder 6, a cutter 7. Spring 8, discharge hole 201, recovery box 202, filter screen 203, material storage box 204, water pump 205, the water tank 2 is located at the left end of the screw extruder 1, the water tank 2 and the screw extruder 1 Threaded connection, the motor 3 is located at the back of the water tank 2, the motor 3 is threaded with the water tank 1, the crankshaft 4 runs through the upper end of the water tank 2, the crankshaft 4 is connected to the water tank 2 in rotation, and the The crankshaft 4 is connected tightly with the motor 3, the backing plate 5 is located inside the water tank 2, the backing plate 5 is threadedly connected with the water tank 2, the cutter holder 6 runs through the crankshaft 4, and the cutter The fixed seat 6 is connected tightly with the crankshaft 4, the cutter 7 is located at the bottom of the fixed seat 6, the cutter 7 is connected with the cutter fixed seat 6 by sliding, and the spring 8 is located at the cutter and fixed Between the seat 6 and the cutter 7, the bottom end of the water tank 2 is also provided with a discharge hole 201, and the bottom end of the water tank 201 is also provided with a recovery box 202, and the recovery box 202 is connected to the water tank 2 by threads.
