Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a granulator for recycling toy injection waste. Background Art

[0002] Toy injection waste refers to the waste generated by the injection molding process during the toy manufacturing process. These wastes usually include defective products, scraps, overflows that are not fully utilized or formed during the injection molding process, and other waste plastic materials in the production process. In order to reduce the waste of resources, toy injection waste will be recycled and granulated for reuse, so a granulator is needed.

[0003] After searching, the patent with patent publication number CN220561934U discloses a plastic granulator, including a base, one side of the top of the base is evenly fixedly connected to two load-bearing seats from left to right, a screening barrel is fixedly connected between the tops of the two load-bearing seats, both sides of the top of the screening barrel are fixedly connected to mounting seats, a crusher is fixedly connected between the tops of the two mounting seats, the top of the inner wall of the screening barrel is rotatably connected to a bending tube, the top of the bending tube passes through the screening barrel and extends to the bottom of the crusher. Compared with the prior art, this utility model has the following beneficial effects: by starting the motor inside the electric drive assembly, the bottom end of the bending tube is driven to rotate around the edge of the screening bucket and discharge the material, thereby extending the screening distance of the transported plastic particles, so that the plastic particles are screened when they are transported from the edge of the screening bucket to the center, and particles of qualified size are screened out, effectively shortening the plastic granulation processing step and improving the plastic granulation processing efficiency.

[0004] The above patents have obvious beneficial effects, but still have the following deficiencies in actual operation:

[0005] In the above-mentioned comparative documents, the crushed plastic particles are screened through a screening bucket. However, in reality, the shapes and sizes of the crushed plastic particles vary. The crushed plastic particles may be stacked in the screening bucket, which will cause partial blockage of the screening bucket, thereby reducing the screening effect. At this time, it is necessary to manually clear the blocked position on the screening bucket, thereby reducing the efficiency of granulating toy injection waste. Therefore, this field urgently needs to improve the toy injection waste recycling granulator to solve the defects of the existing technology. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1

[0029] See also Figures 1-6 The toy injection waste recycling granulator includes a screening box 1, a crushing box 2 connected to the screening box 1 is provided on the upper part of the screening box 1, two symmetrical crushing rollers 3 for crushing are provided in the crushing box 2, a bucket-shaped screening funnel 4 is provided in the screening box 1, and a conical guide seat 5 is provided in the lower part of the crushing box 2. A first drive motor 6 is fixedly installed on the lower surface of the conical guide seat 5, and a rotating shaft 7 is fixedly installed on the output end of the first drive motor 6. A cleaning frame 8 adapted to the screening funnel 4 is fixedly installed on the side of the rotating shaft 7. A first discharge pipe 9 for discharging is fixedly installed at the lower part of the screening box 1, and a second discharge pipe 10 extending to the outside is fixedly installed at the lower opening position of the screening funnel 4.

[0030] The specific implementation method of this embodiment is as follows: when it is necessary to recycle the toy injection waste, the toy injection waste is put into the crushing box 2, and the toy injection waste is crushed by two symmetrical crushing rollers 3. The crushed material falls to the upper side of the conical guide seat 5. The conical guide seat 5 is conical in shape, so the crushed material will be guided to the inner side of the screening box 1. The first drive motor 6 is turned on, and the output end of the first drive motor 6 drives the rotating shaft 7 to rotate. The rotating shaft 7 drives several cleaning racks 8 to rotate. One side of the cleaning rack 8 is connected to the inner side of the screening funnel 4. The side walls are against each other, and the material falls on the screening funnel 4. The screening funnel 4 is bucket-shaped, so the material will flow to the second discharge pipe 10. During the flow, some granular materials are screened by the screening funnel 4 and fall to the bottom of the screening box 1, and are discharged through the first discharge pipe 9. Unqualified materials will gradually flow to the second discharge pipe 10 and finally be discharged through the second discharge pipe 10. The rotating cleaning rack 8 can prevent blockage caused by accumulation on the screening funnel 4, thereby improving the efficiency of recycling and granulating toy injection waste.

[0031] Example 2

[0032] See also Figure 1 、 Figure 2 and Figure 5 This embodiment includes the above embodiment, which further includes: a second drive motor 11 is fixedly installed on one side of the crushing box 2, one end of each of the two crushing rollers 3 is fixedly connected to a rotating shaft 12 whose end extends to the outside, and a gear 13 is fixedly installed on the side of one end of the two rotating shafts 12 located on the outside, and the two gears 13 are meshed with each other, and the output end of the second drive motor 11 is fixedly connected to one of the rotating shafts 12.

[0033] The specific implementation method in this embodiment is as follows: when it is necessary to crush the toy injection waste, the toy injection waste is put into the crushing box 2, and the second drive motor 11 is turned on. The output end of the second drive motor 11 drives one of the rotating shafts 12 to rotate, and the rotating shaft 12 drives one of the gears 13 to rotate, and the gear 13 drives another gear 13 to rotate. The two gears 13 simultaneously drive the crushing rollers 3 to rotate in opposite directions, thereby improving the efficiency of crushing the toy injection waste.

[0036] Specific implementation method in this embodiment: Since the toy injection waste is light in weight, when it is crushed, the toy injection waste may be stacked on the two crushing rollers 3, causing the two crushing rollers 3 to be unable to crush it. At this time, the telescopic device 16 is started, and the telescopic end of the telescopic device 16 drives the pressure plate 15 to move downward, pressing down the toy injection waste on the upper part of the crushing box 2, forcing the toy injection waste to move downward, and the operator does not need to manually handle the stacked toy injection waste, thereby improving safety and the efficiency of crushing the toy injection waste, thereby improving the granulation efficiency of the entire granulation device.

[0039] Specific implementation method in this embodiment: When the screening funnel 4 needs to be installed or replaced later, the crushing box 2 installed on the screening box 1 by fasteners can be disassembled, and the box cover 17 installed by fasteners can be disassembled, and the crushing box 2 can be moved away by lifting equipment. At this time, the first drive motor 6 and the cleaning frame 8 are directly removed through the connecting rod 20, and the screening funnel 4 is directly taken out, and the plug-in block 18 on the side of the new screening funnel 4 is aligned with the plug-in slot 19 and inserted to complete the installation of the screening funnel 4, which is convenient for the installation or later replacement of the screening funnel 4.
