[0001] The utility model belongs to the technical field of recycling waste plastic bottles, and in particular relates to a crushing device used for recycling waste plastic bottles. Background Art

[0002] Recycling and crushing used plastic bottles can reuse plastic resources and reduce the demand for virgin plastic. Through crushing, used plastic bottles can be converted into reprocessable plastic fragments or particles for the production of new plastic products.

[0003] Most of the existing crushing equipment for recycling waste plastic bottles adopts crushing rollers or crushing blades to achieve the crushing function. Since the crushing rollers or crushing blades are squeezed with the plastic bottles during operation, a large noise is generated, which not only causes noise pollution, but also has an adverse effect on the health of operators in the working environment; secondly, the use of crushing rollers or crushing blades requires continuous input of plastic bottles, and the continuous amount of plastic bottles crushed is small. If more plastic bottles are input, it is easy to cause problems such as jamming and damage of the crushing rollers or crushing blades, increasing the maintenance cost of the equipment.

[0004] Therefore, it is necessary to propose a crushing device for recycling waste plastic bottles. Utility Model Content

[0022] This specific embodiment is a crushing device for recycling waste plastic bottles, and its structural schematic diagram is shown in FIG. Figure 1-Figure 6 As shown, it includes a base plate 1, which is U-shaped. A storage box 2 is arranged on the inner side of the base plate 1. The left and right side walls of the storage box 2 are respectively fixedly connected with a rotating shaft 4, and the other ends of the rotating shaft 4 are rotatably connected to the base plate 1. A filter plate 3 is fixedly connected to the inner wall of the storage box 2 near the bottom end. A plurality of cutting grooves 5 are opened on the top end face of the storage box 2. A flip assembly is arranged on the side wall of the right rotating shaft 4. A support plate 6 is fixedly connected to the left side wall of the base plate 1. An electric slide rail 7 is installed on the side wall of the support plate 6. A slider 8 is installed on the side wall of the electric slide rail 7. A rectangular frame 9 is fixedly connected to the side wall of the slider 8. A plurality of heating wires 10 are fixedly connected to the inner wall of the rectangular frame 9. A dust collection assembly is arranged on the side wall of the rectangular frame 9.

[0023] like Figure 1 and Figure 4 As shown, the flip assembly includes a gear 11 fixedly connected to the side wall of the rotating shaft 4, a rack 12 is meshed on the lower side of the gear 11, an electric push rod 13 is fixedly installed on the right side wall of the bottom plate 1, and the output end of the electric push rod 13 is fixedly connected to the rack 12. A protective cover 14 is fixedly connected to the right side wall of the bottom plate 1, and the electric push rod 13 is located inside the protective cover 14.

[0024] Through the design of the bottom plate 1, storage box 2, support plate 6, rectangular frame 9 and heating wire 10, the high temperature generated by the heating wire 10 is used to cut multiple plastic bottles. On the one hand, it effectively solves the noise generated in the crushing process of traditional crushing rollers and reduces the noise pollution of the operating environment. On the other hand, a large number of waste plastic bottles can be cut quickly. Compared with the existing continuous crushing method, this solution has the characteristics of large single crushing volume, flat crushed end surface of plastic bottles, convenient maintenance, and no noise pollution.

[0025] like Figure 2 and Figure 5 As shown, a winding roller 15 is installed on the top surface of the support plate 6, and a hose 16 is wrapped around the side wall of the winding roller 15. An annular cavity 17 is opened inside the side wall of the rectangular frame 9, and a plurality of through holes 18 are opened on the side wall of the annular cavity 17 close to the heating wire 10, and the hose 16 is connected to the through holes 18.

[0026] Specifically, the winding roller 15 can realize the automatic winding and unwinding function, which is an existing mature technology, and therefore serves as an auxiliary function in this solution.

[0027] like Figure 2 and Figure 4 As shown, two T-shaped slots 21 are provided on the right end surface of the support plate 6 , and T-shaped blocks 20 are disposed in each of the T-shaped slots 21 . The bottom surfaces of the two T-shaped blocks 20 are fixedly connected to the same protective shell 19 .

[0028] Specifically, during use, the protective shell 19 can be inserted into the T-shaped slot 21 through the T-shaped block 20, so that the rectangular frame 9 is located in the protective shell 19 in the initial state. On the one hand, it is convenient to absorb and discharge the odor generated when plastic material adheres to the heating wire 10, and on the other hand, it avoids the high temperature generated by the heating wire 10 to cause safety hazards to the operator.

[0029] like Figure 2 and Figure 3 As shown, the heating wires 10 are arranged crosswise, and the heating wires 10 correspond to the cutting grooves 5 .

[0030] Specifically, the gaps between the heating wires 10 are distributed in a rectangular shape, so that after the plastic bottle is cut, the complete plastic bottle is divided into several fragments; and the material of the heating wire 10 can be any one of the following:

[0031] Nichrome wire: Commonly used Nichrome wire can reach a temperature of 900℃-1350℃ (1652℉-2462℉);

[0032] Tungsten wire: Tungsten wire has excellent high temperature resistance and can reach temperatures above 3000℃ (5432℉). It is usually used in more extreme high temperature applications, such as vacuum furnaces and electronic equipment.

[0033] Silicon Carbide resistance wire: Silicon carbide resistance wire can withstand temperatures up to 1600°C (2912°F), and has a low thermal diffusion coefficient and good chemical stability. It can be used in high-temperature heating, sintering, furnace tubes and other fields;

[0034] Platinum wire: Platinum wire can withstand temperatures up to 1770°C (3218°F), has high oxidation resistance and chemical stability, and is commonly used in laboratory equipment, high-temperature furnaces, and thermocouples.

[0035] Working principle: First, the heating wire 10 is energized to generate high temperature, then a proper amount of plastic bottles are put into the storage box 2, and then the electric slide rail 7 is operated. The slider 8 drives the heating wire 10 to move downward along the electric slide rail 7. When the heating wire 10 contacts the plastic bottle, the high temperature of the heating wire 10 can instantly melt the plastic bottle. Through the cross distribution of the heating wire 10, the plastic bottle can be quickly cut into several pieces, effectively solving the noise generated by traditional crushing.

[0036] At the same time, the hose 16 is connected to the external exhaust device, and the rectangular frame 9 moves downward while driving the hose 16 downward, and the winding roller 15 can automatically release the hose, and the external exhaust device generates negative pressure, so that the smoke generated during the cutting and crushing process can be sucked into the hose 16 through the through hole 18 and discharged, ensuring the installation of the working environment;

[0037] When the plastic bottles are cut, the electric push rod 13 is started to push the rack 12 to move. The rack 12 engages the gear 11 and drives the shaft 4 to rotate. After the shaft 4 drives the storage box 2 to rotate to a suitable angle, the broken plastic bottles fall due to their own gravity. Then the electric push rod 13 drives the storage box 2 to reset and repeat the next breaking process.

[0038] All technical features in this embodiment can be freely combined according to actual needs.

[0039] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
