[0002] PVB resin is a resin synthesized through a specific chemical reaction. It has high transparency, good cold resistance, water resistance, film-forming properties and impact resistance. It is widely used in many fields. PVB resin extrusion granulation is a processing technology used to process PVB resin raw materials into granules for easier subsequent molding processing.

[0003] The existing PVB resin extrusion granulation usually involves placing the PVB resin raw material into a screw extruder, heating and melting it, then extruding it into continuous strips through the screw, and then cutting it into particles of uniform size. However, since the cutting speed cannot be adjusted according to the change in the feed rate of the blade, the PVB resin particles may be uneven in size, affecting product quality.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] A PVB resin extrusion granulation device, such as Figure 1-Figure 3As shown, it includes a base 1, a barrel 2, a motor 3, a liquid receiving barrel 4, a liquid frame 5, a central axis 6, a paddle 7, a bifurcated rod 8, a heat dissipation ring 9, a granulation disk 10, a sweeping plate 11 and a sieve plate 13. The base 1 has two left and right sides, and the barrel 2 is connected between the bases 1. The right side of the barrel 2 is connected to the motor 3, and the liquid receiving barrel 4 is connected to the output shaft of the motor 3. The liquid receiving barrel 4 is provided with six liquid outlet holes. The right side of the barrel 2 is also connected to the liquid frame 5, and the blade connecting barrel is rotatably connected to the liquid frame 5. The barrel 2 is rotatably connected to the central axis 6 inside, and the central axis 6 is a hollow structure. The central axis 6 is connected to the blade connecting barrel, and the paddle 7 is connected to the central axis 6. A plurality of bifurcated rods 8 are connected to the paddle 7. The left side of the barrel 2 is connected to a heat dissipation ring 9, and the granulation disk 10 is connected to the inner side of the heat dissipation ring 9. The left side of the granulation disk 10 is rotatably connected to the sweeping plate 11. The left side of the lower part of the heat dissipation ring 9 is connected to a material trough 12, and the sieve plate 13 is connected to the material trough 12.

[0019] When using the utility model, firstly, the base 1 is placed in the PVB resin extrusion and granulation area, and then the high-temperature liquid is added into the liquid frame 5, so that the high-temperature liquid flows from the liquid frame 5 into the liquid receiving cylinder 4, and then from the liquid receiving cylinder 4 into the central axis 6, and then flows into the inside of the paddle to heat the barrel 2, and then the PVB resin raw material is poured into the barrel 2 from the discharge port, and then the motor 3 is started to rotate the liquid receiving cylinder 4, so that the central axis 6 rotates, and the paddle 7 rotates to stir the PVB resin raw material, so that the PVB resin raw material is evenly heated and melted, and the molten PVB resin raw material is extruded from the granulation disk 10 while the paddle 7 rotates, and when the paddle rotates, the bifurcated rod 8 rotates to stir the PVB resin raw material evenly to prevent the PVB resin raw material from piling up and agglomerating, and when the central axis 6 rotates, the sweeping plate 11 rotates to cut the extruded PVB resin raw material into particles. When the motor 3 rotates faster, the central axis 6 rotates faster, the paddle 7 rotates faster, the extrusion rate of the PVB resin raw material becomes faster, and the sweeping plate 11 rotates faster, and the cutting rate of the extruded PVB resin raw material becomes faster, so that the cutting speed of the sweeping plate 11 can be adjusted according to the feeding rate of the paddle, so as to ensure that the size of the PVB resin particles is uneven and improve the production quality of the PVB resin. After cutting, the PVB resin raw material falls into the heat dissipation ring 9 for heat dissipation, and it is convenient to sample and detect the PVB resin raw material. After cooling, it falls on the sieve plate 13 on the trough 12. When the motor 3 rotates, the motor 3 will vibrate when it is running, which will drive the trough 12 to vibrate, so that the sieve plate 13 screens the PVB resin raw material, and the screened PVB resin raw material falls into the trough 12 for collection.
