[0035] The present utility model will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] This embodiment relates to a plastic raw material granulator. In terms of the overall structure, as Figure 1 and Figure 2 shown, it includes a machine body 1, a screw conveyor 3, a heating jacket 4, an extrusion assembly 5, and a cutting assembly 6.

[0037] Among them, an outer cylinder 2 is horizontally arranged on the upper part of the machine body 1, the screw conveyor 3 is rotatably arranged inside the outer cylinder 2, multiple heating jackets 4 are arranged on the outer cylinder 2, the extrusion assembly 5 is fixedly arranged at the outlet of the outer cylinder 2, and the cutting assembly 6 is fixedly arranged at the tail end of the machine body 1 and is located at the outlet of the extrusion assembly 5.

[0038] It is worth mentioning that the machine body 1 is used to support the outer cylinder 2. One end of the outer cylinder 2 is provided with a feed inlet, and the raw material enters from the feed inlet. The screw conveyor 3 is driven by a motor, so that the screw conveyor 3 rotates inside the outer cylinder 2 to convey the raw material to the extrusion assembly 5 for discharging. The outlet is located at the end of the outer cylinder 2. The heating jacket 4 can ensure that the raw material inside the outer cylinder 2 remains in a molten state. The screw conveyor 3 transports the raw material to the outlet. The extrusion assembly 5 is located at the outlet. Therefore, the extrusion assembly 5 can extrude the raw material, and then the cutting assembly 6 cuts the extruded raw material into equal-sized particles, thus completing granulation.

[0039] Based on the above overall introduction, an exemplary structure of the plastic raw material granulator in this embodiment is still as Figure 1 and Figure 2 shown. A connecting piece 7 is arranged between the extrusion assembly 5 and the outer cylinder 2, and a support piece 8 is arranged at the tail end of the machine body 1. The cutting assembly 6 is fixedly arranged on the support piece 8. Specifically, the connecting piece 7 can install the extrusion assembly 5 at the outlet of the outer cylinder 2. Since multiple through holes are opened on the extrusion assembly 5 and the raw material is extruded from the through holes, and the through holes are prone to blockage, the purpose of arranging the connecting piece 7 is to facilitate the removal of the extrusion assembly 5 for cleaning. The support piece 8 can ensure that the cutting assembly 6 is located at the outlet of the extrusion assembly 5, enabling the cutting assembly 6 to cut the raw material extruded by the extrusion assembly 5, thus realizing granulation. The support piece 8 can facilitate the installation and movement of the cutting assembly 6.

[0040] As a preferred embodiment, as Figure 4As shown, the extrusion assembly 5 of this embodiment includes an enlarging sleeve 501 fixedly arranged at the outlet of the outer cylinder 2, a perforated plate 502 fixedly arranged at the outlet of the outer cylinder 2, and a head 503 fixedly arranged at one end of the enlarging sleeve 501 away from the perforated plate 502. The cutting assembly 6 is located at the head 503. The plastic raw material is discharged from the head 503 and cut into particles by the cutting assembly 6. A flow dividing cone 504 is arranged in the middle of the head 503, and the tip of the flow dividing cone 504 is close to the perforated plate 502.

[0041] It should be noted that the enlarging sleeve 501 and the outer cylinder 2 are coaxially arranged. The perforated plate 502 is located between the enlarging sleeve 501 and the outer cylinder 2, that is to say, the perforated plate 502 is located at the outlet of the outer cylinder 2. When the raw material enters the perforated plate 502 from the outlet, the raw material can be evenly distributed to avoid uneven melting of the raw material, and then enters the enlarging sleeve 501. Due to the setting of the flow dividing cone 504, the raw material is located on the outer ring of the flow dividing cone 504 and is discharged from the head 503. A plurality of through holes are arranged on both the perforated plate 502 and the head 503. After the raw material is discharged from the head 503, it can be cooled by air cooling. Air cooling is a common cooling method in the prior art, so it is not mentioned here and will not be elaborated further. After the raw material is discharged from the head 503, it passes through the cutting mechanism to cut the strip-shaped raw material into particles of uniform size.

[0042] Preferably, as Figure 5 shown, the connecting member 7 of this embodiment includes two support plates 701 fixedly arranged on opposite sides of the side wall of the outer cylinder 2, and two limiting rods 702 fixedly arranged on opposite sides of the side wall of the enlarging sleeve 501. The limiting rods 702 and the support plates 701 are fastened by fasteners. Specifically, the support plate 701 is preferably an L-shaped plate, and the fastener can rotate on the L-shaped rod. The limiting rods 702 and the support plates 701 are located at the same position, and the fastener can fasten the support plate 701 and the limiting rod 702 together. That is to say, multiple groups of the limiting rods 702 and the support plates 701 can be evenly arranged on the enlarging sleeve 501 and the outer cylinder 2 to improve the fastening property of the outer cylinder 2 and the enlarging sleeve 501.

[0043] Preferably, still as Figure 5 shown, the fastener of this embodiment includes a horizontal shaft 704 rotatably arranged on the support plate 701, a screw rod 703 fixedly arranged on the horizontal shaft 704, a knob 706 screwed on the screw rod 703. A groove 705 is formed on the limiting rod 702, the screw rod 703 is located in the groove 705, and the knob 706 abuts against the limiting rod 702.

[0044] Specifically, the screw rod 703 can be welded to the middle of the horizontal shaft 704. The horizontal shaft 704 is inserted into the support plate 701 and rotates on the support plate 701, so as to realize the swing of the screw rod 703 on the support plate 701. When the screw rod 703 swings into the groove 705 of the limiting rod 702, rotate the knob 706, and the knob 706 can push the limiting rod 702 to move towards the support plate 701, that is, the magnifying sleeve 501 is fixed on the outer cylinder 2. By rotating the knob 706 in the reverse direction, the screw rod 703 can be separated from the groove 705 of the limiting rod 702, so as to remove the magnifying sleeve 501 from the outer cylinder 2.

[0045] Preferably, still as Figure 5 shown, the groove 705 of this embodiment is opened on one of the limiting rods 702, and a strip-shaped hole 707 is opened on the other limiting rod 702. One of the horizontal shafts 704 is located in the strip-shaped hole 707, and the screw rod 703 on this horizontal shaft 704 is inserted into the limiting rod 702 with the strip-shaped hole 707.

[0046] Specifically, the magnifying sleeve 501 can also be rotated and opened from the outer cylinder 2. When the magnifying sleeve 501 rotates, the limiting rod 702 with the strip-shaped hole 707 rotates at this horizontal shaft 704, and the screw rod 703 on this horizontal shaft 704 rotates following the limiting rod 702, while the other screw rod 703 can swing out from the limiting rod 702 with the groove 705, so as to realize that the magnifying sleeve 501 can be rotated and opened.

[0047] In addition, when it is necessary to fasten the magnifying sleeve 501 to the outer cylinder 2, rotate the magnifying sleeve 501 to fit with the outer cylinder 2. The same as above, the strip-shaped hole 707 rotates on the horizontal shaft 704, and then the screw rod 703 swings into the groove 705. Rotate the knob 706, and the knob 706 fastens the limiting rod 702 to the support plate 701. The screw rod 703 that rotates following the limiting rod 702 is inserted into the limiting rod 702 and can slide in this limiting rod 702. At this time, rotate the knob 706, and the knob 706 pushes the limiting rod 702 with the strip-shaped hole 707 to move towards the support plate 701. At the same time, the strip-shaped hole 707 slides on the horizontal shaft 704, so as to realize that the limiting rod 702 is fastened to the support plate 701, ensuring that both limiting rods 702 can be fixed on the support plate 701. Multiple groups of limiting rods 702 with grooves 705 can be provided to ensure the installation strength of the magnifying sleeve 501.

[0048] As a preferred implementation manner, as Figure 6As shown, in this embodiment, the cutting assembly 6 includes a motor 601 fixedly arranged on the support member 8, and a scraper 602 rotatably arranged at the driving end of the motor 601. The scraper 602 contacts the machine head 503, and a blanking bin 603 is fixedly arranged on the machine body 1. It should be noted that the motor 601 can drive the scraper 602 to rotate. The scraper 602 is vertically arranged with respect to the driving shaft of the motor 601, and a plurality of scrapers 602 are arranged circumferentially around the driving shaft of the motor 601. The scraper 602 can tightly cut the raw materials discharged from the through-hole of the machine head 503. To prevent the raw materials from splashing, the blanking bin 603 is provided to ensure that the particles are discharged from the outlet of the blanking bin 603.

[0049] Preferably, as Figure 3 shown, the support member 8 of this embodiment includes a stud 801 screwed onto the machine body 1, a bracket 802 screwed onto the stud 801, the motor 601 is fixedly arranged on the bracket 802, and a nut 803 is screwed onto the stud 801. Specifically, first screw the stud 801 onto the bracket 802, and then screw the stud 801 onto the machine body 1. The stud 801 is fastened to the machine body 1 by the nut 803. The motor 601 is installed on the bracket 802 to ensure that the driving shaft of the motor 601 and the machine head 503 are coaxial. The blanking bin 603 is installed on the bracket 802 and sleeved at the position of the machine head 503 to prevent the particles from splashing. The air cooling can be connected to the blanking bin 603 to improve the cooling speed of the particles.

[0050] In the plastic raw material granulator of this embodiment, through the setting of the extrusion assembly 5, it is ensured that the raw materials can be evenly conveyed to the machine head 503, improving the granulation quality. Through the setting of the cutting assembly 6, it is ensured that the extruded raw materials can be evenly cut, also improving the granulation quality. Through the setting of the connecting member 7, it is ensured that the extrusion assembly 5 is convenient for disassembly and assembly, thus facilitating the cleaning of the machine head 503 and improving the working efficiency.
