[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0028] The utility model provides a technical solution:
[0029] See also Figures 1 to 5A multi-stage crushing plastic particle production crusher includes a processing box 1, a storage shell 2 is slidably connected to the bottom of the top of the processing box 1, a crushing box 3 is fixedly installed on the top of the processing box 1, a crushing roller 4 is rotatably connected to the inside of the crushing box 3, and a crushing mechanism 5 is embedded on the top of the crushing box 3; the crushing mechanism 5 includes a motor 501, the motor 501 is embedded on one side of the top of the crushing box 3, the power output end of the motor 501 is connected to the driving rod 502, and a first crushing chamber 504 is fixedly installed on the top of the crushing box 3. A telescopic plate 505 is passed through the bottom end of 504, and a filter cartridge 506 is passed through the bottom of the telescopic plate 505. A second crushing chamber 507 is embedded in the upper part of the interior of the filter cartridge 506. A crushing knife 503 is fixedly installed on the outer wall of the driving rod 502. The filter cartridge 506 fits tightly against the telescopic plate 505. A sliding structure is formed between the telescopic plate 505 and the first crushing chamber 504. The driving rod 502 passes through the outer wall of one end of the filter cartridge 506 and is fixedly installed with a fixed plate 6. The end of the fixed plate 6 away from the driving rod 502 is rotatably connected to a resistance roller 7.
[0030] By adopting the above technical solution, the plastic is first preliminarily crushed by the crushing roller 4 inside the crushing box 3, and then guided to the first crushing chamber 504 of the processing box 1. The first crushing chamber 504 is connected to the filter cartridge 506 and the second crushing chamber 507 through the telescopic plate 505 to facilitate the circulation of plastic. At the same time, the driving rod 502 is provided with three groups of crushing knives 503, corresponding to the entire interior of the first crushing chamber 504 and the upper and lower parts of the second crushing chamber 507. Driven by the motor 501 and the driving rod 502, the plastic can be fully divided, cut and crushed, and the strip-shaped and surface-shaped plastic can be crushed until the size meets the requirements. After being filtered in the second crushing chamber 507, it enters the filter cartridge 506. At the same time, the fixed plate 6 pushes the plastic to move in accordance with the filter cartridge 506 under the drive of the driving rod 502, so that it falls into the storage shell 2 for unified collection after being filtered again. The resistance roller 7 at one end of the fixed plate 6 rolls along the filter cartridge 506 to avoid blockage.
[0031] Specifically, such as Figures 4 to 6 As shown, a support plate 8 is embedded in the lower part of the interior of the processing box 1, and an adjusting mechanism 9 is provided inside the support plate 8. The adjusting mechanism 9 includes a rotating block 901, which is embedded in the inner bottom end of the filter cartridge 506. A hydraulic rod 902 is rotatably connected to the lower part of the rotating block 901. The adjusting mechanism 9 also includes a limit block 903, which is fixed to the top of the rotating block 901. A positioning block 904 is fixedly installed at the bottom end of the driving rod 502. The filter cartridge 506 forms a rotating structure through the rotating block 901 and the hydraulic rod 902, and the filter cartridge 506 forms a sliding structure through the hydraulic rod 902 and the telescopic plate 505.
[0032] By adopting the above technical solution, the hydraulic rod 902 drives the rotating block 901 to move under the embedding of the support plate 8. When the filter cartridge 506 needs to be fixed, the hydraulic rod 902 contracts the filter cartridge 506 and presses the support plate 8 to limit it, so as to prevent the fixed plate 6 and the contact roller 7 from contacting the filter cartridge 506 and causing it to slide. When the crushing is completed and cleaned, the hydraulic rod 902 is extended to allow the rotating block 901 to drive the limiting block 903 to fit the positioning block 904, and the driving rod 502 drives the positioning block 904 to rotate under the drive of the motor 501, so that the positioning block 904 penetrates and engages, which enables the filter cartridge 506 to drive the centrifugal movement of the plastic particles to avoid accumulation and waste. At the same time, the telescopic plate 505 allows the filter cartridge 506 to maintain rotational stability.
[0033] Working principle: The bottom of the crushing box 3 is an inclined structure. The objects crushed by the crushing roller 4 enter the first crushing chamber 504 of the processing box 1. The first crushing chamber 504 penetrates the filter cylinder 506 through the telescopic plate 505 and communicates with the second crushing chamber 507. Under the drive of the motor 501 and the driving rod 502, three groups of crushing knives 503 of different sizes are driven to crush the corresponding first crushing chamber 504 and the upper and lower parts of the second crushing chamber 507. Multiple crushing knives 503 form a group, which can crush strip or surface plastics until they meet the crushing size, are filtered through the second crushing chamber 507, and enter the filter cylinder 506. They are pushed by the fixed plate 6. At the same time, the fixed plate 6 rotates and the connected friction roller 7 fits the filter cartridge 506 to avoid clogging. When the crushing operation is completed, the motor 501 stops working. Then, the hydraulic rod 902, supported by the support plate 8, pushes the rotating block 901 to make the filter cartridge 506 rise. At the same time, the motor 501 works again, so that the limit block 903 of the rotating block 901 rotates along the positioning block 904 until it enters the reserved hole for engagement, allowing the filter cartridge 506 to rotate, driving the internal debris to perform centrifugal motion, avoiding the situation where accumulation cannot flow out and cause waste, and finally enters the storage shell 2 for convenient unified collection.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
