Description

Technical Field

[0001] The present application relates to the field of shredders, and in particular to a circulating shredder. Background Art

[0002] A shredder is a machine used for shredding, generally used to process unprocessed raw materials or scraps to make them smaller in size. When shredding, the raw materials or scraps are first poured into the shredder's feed port. The raw materials or scraps poured into the shredder are shredded by the shredder's shredder blades, and then discharged from the discharge channel. Currently, most commonly used shredders are multi-axis shredders, which can drive multiple shredding blades to shred the raw materials or scraps through multi-axis rotation. However, there are gaps between the multiple shredding blades, which will cause some raw materials or scraps to fall into the discharge channel without being completely shredded, and require secondary shredding, resulting in low shredding efficiency. At the same time, the scraps that are not completely shredded will be mixed with the completely shredded scraps, reducing the shredding quality of the shredder. Utility Model Content

Figure 1 The circulating shredder includes a housing 1, a shredding chamber 11 is provided in the housing 1, a feed hopper 2 is fixedly connected to the top of the housing 1 and communicates with the interior of the shredding chamber 11, a shredding mechanism 3 is rotatably connected to the interior of the shredding chamber 11, and the housing 1 is also provided with a circulation mechanism 4 for secondary shredding of unshredded scraps, a cleaning mechanism 5 for cleaning the shredded scraps, and a discharge mechanism 6 for collecting the shredded scraps. When in use, the scraps to be shredded are first poured from the feed hopper 2 into the shredding chamber 11, the shredding mechanism 3 is activated to shred the scraps, and after the shredding mechanism 3 has worked for a period of time, the circulation mechanism 4 is activated to secondary shred the scraps that have not been completely shredded. The shredded scraps are cleaned by the cleaning mechanism 5 and then discharged from the discharge mechanism 6. By using a circulating shredder, the leftover materials that are not completely shredded by the shredder can be recycled and shredded, so that the leftover materials do not need to be poured into the shredder again for secondary shredding. At the same time, the leftover materials that are not completely shredded are prevented from being mixed with the leftover materials that are completely shredded, thereby improving the shredding efficiency and quality of the shredder.

[0034] Reference Figure 1 and Figure 2The shredding mechanism 3 includes a first cutter shaft 31 and a second cutter shaft 32 which are rotatably connected to the shredding chamber 11 at a horizontal interval. A third cutter shaft 33 is also rotatably connected to the shredding chamber 11. The third cutter shaft 33 is arranged between the first cutter shaft 31 and the second cutter shaft 32 and is located on the side of the first cutter shaft 31 and the second cutter shaft 32 away from the feed funnel 2. Blades are fixed to the first cutter shaft 31, the second cutter shaft 32 and the third cutter shaft 33. The blades of the first cutter shaft 31, the second cutter shaft 32 and the third cutter shaft 33 are staggered and matched with each other.

[0035] A motor 34 for driving the third cutter shaft 33 is also provided on one side of the housing 1. A speed reducer 35 is mounted on the motor 34 to control the speed of the third cutter shaft 33. It is understood that gears are fixedly connected to the first cutter shaft 31, the second cutter shaft 32, and the third cutter shaft 33, and the gears of the first cutter shaft 31 and the second cutter shaft 32 respectively mesh with the gears of the third cutter shaft 33. During use, the motor 34 is started, and the motor 34 drives the third cutter shaft 33 to rotate, causing the first cutter shaft 31 and the second cutter shaft 32, which are meshed with the gears of the third cutter shaft 33, to also rotate. The scraps poured into the shredding chamber 11 are shredded into smaller scraps by the blades of the first cutter shaft 31, the second cutter shaft 32, and the third cutter shaft 33.

[0036] The circulation mechanism 4 includes a first fan 41 fixedly connected to the outside of the housing 1 and located on the side of the third blade shaft 33 away from the feed hopper 2. A first air port 42 is defined in the housing 1. The first fan 41 communicates with the interior of the shredding chamber 11 through the first air port 42. The air inlet of the first fan 41 faces outward, and the air outlet faces the shredding chamber 11. Multiple first fans 41 can be provided as needed. A first filter 43 is fixedly connected to the inner wall of the first air port 42.

[0037] A second filter 12 for filtering shredded scraps is fixedly connected horizontally to the bottom of the shredding chamber 11. The second filter 12 filters out scraps that meet the shredding requirements, while scraps that do not meet the requirements accumulate on the second filter 12 and remain in the shredding chamber 11. During use, the first fan 41 is activated, blowing air into the shredding chamber 11, driving the scraps that do not meet the requirements accumulated on the second filter 12 toward the shredding mechanism 3, causing them to fall back onto the shredding mechanism 3 and be shredded a second time by the blades of the first, second, and third blade shafts 31, 32, and 33.

[0038] The cleaning mechanism 5 includes a third filter 51, which is horizontally fixed to the interior of the housing 1 and located on the side of the second filter 12 away from the shredding chamber 11; and a dust box 52, which is removably mounted within the housing 1 and located on the side of the third filter 51 away from the second filter 12. The filter holes in the third filter 51 are of a relatively small diameter, allowing dust and other fine impurities to pass through the third filter 51 while preventing scraps from passing through. During operation, scraps that meet the requirements after being filtered by the second filter 12 fall onto the third filter 51. Dust and other impurities in the scraps are filtered by the third filter 51 and fall into the dust box 52 below, while scraps remain accumulated on the third filter 51.

[0039] A mounting opening 53 is provided on one side of the box body 1, through which the dust box 52 can be inserted into the box body 1. A handle 521 is fixedly connected to one side of the dust box 52 near the mounting opening 53. When in use, a worker can pull the handle 521 to pull the dust box 52 out of the box body 1 to facilitate emptying the dust in the dust box 52.

[0040] The discharge mechanism 6 includes a discharge pipe 61 fixed to one side of the housing 1 and communicating with the interior of the housing 1, a second fan 62 fixed to the side of the housing 1 away from the discharge pipe 61, a pusher 63 for pushing the scraps accumulated on the third filter screen 51 into the discharge pipe 61, and a scrap box 64 located at the end of the discharge pipe 61 away from the housing 1. The discharge pipe 61 is arranged in an inclined shape, with the slope of the discharge pipe 61 gradually decreasing from the end close to the housing 1 to the end close to the scrap box 64. The lower pipe wall of the discharge pipe 61 is located on the same horizontal plane as the third filter screen 51.

[0041] The housing 1 is provided with a second air vent 65, through which the second fan 62 communicates with the interior of the housing 1. A fourth filter 66 is fixedly attached to the inner wall of the second air vent 65. An air inlet pipe 67, communicating with the second air vent 65, is fixedly attached to the inner wall of the housing 1. The air inlet pipe 67 is arranged at an angle, with the end of the air inlet pipe 67 away from the second air vent 65 facing the third filter 51. During operation, the second fan 62 is activated, driving air along the air inlet pipe 67 into the housing 1, thereby blowing any scrap material accumulated on the third filter 51 into the discharge pipe 61.

[0042] The pusher 63 includes a pusher box 631 fixed to the side of the box body 1 away from the discharge pipe 61, a cylinder 632 fixed to the side of the pusher box 631 facing the discharge pipe 61, and a pusher plate 633 fixed to the piston rod of the cylinder 632. The pusher box 631 is connected to the interior of the box body 1 through a pusher hole 634 provided in the box body 1, and the pusher plate 633 can be precisely inserted into the pusher hole 634. Under normal conditions, the piston rod of the cylinder 632 drives the pusher plate 633 to be located in the pusher hole 634. After the scrap material is shredded, the cylinder 632 is activated, and the piston rod of the cylinder 632 extends to push the scrap material that has not been blown into the discharge pipe 61 by the second fan 62 into the discharge pipe 61, thereby completing the scrap material discharge.

[0043] In order to facilitate the observation of the shredding of the edge material and the observation of the blanking situation, a transparent observation window 13 is also provided on the side wall of the casing 1. The transparent observation window 13 can be respectively provided with one on the side wall of the casing 1 facing the shredding chamber 11 and facing the cleaning mechanism 5.

[0044] The operating principle of the circulating shredder according to the embodiment of the present application is as follows: when in use, the scraps to be shredded are first poured into the shredding chamber 11 through the feed funnel 2, and then the motor 34 is started. The motor 34 drives the third cutter shaft 33, the first cutter shaft 31, and the second cutter shaft 32 to rotate, so that the blades of the first cutter shaft 31, the second cutter shaft 32, and the third cutter shaft 33 shred the scraps poured into the shredding chamber 11 into smaller scraps. The scraps that meet the requirements are filtered through the second filter screen 12 and fall onto the third filter screen 51 below. After observing through the transparent observation window 13 that the scraps that do not meet the requirements have accumulated to a certain extent on the second filter screen 12, the worker can start the first fan 41. The first fan 41 blows air into the shredding chamber 11, driving the scraps accumulated on the second filter screen 12 toward the shredding mechanism 3, causing the scraps to fall onto the shredding mechanism 3 again for secondary shredding. The scraps that fall onto the third filter screen 51 are filtered by the third filter screen 51 to remove impurities such as dust mixed in them. After shredding is complete, the second blower 62 is activated to blow the scraps accumulated on the third filter screen 51 into the discharge pipe 61. Workers can observe through the transparent window whether there is any scrap left on the third filter screen 51. If so, the cylinder 632 can be activated. The piston rod of the cylinder 632 extends, driving the push plate 633 to push the scraps accumulated on the third filter screen 51 into the discharge pipe 61, so that the scraps slide along the slope of the discharge pipe 61 into the scrap box 64 to complete the discharge. A circulating shredder eliminates the need to pour the unshredded scraps back into the shredder for secondary shredding. Instead, the unshredded scraps can be recycled and shredded directly in the shredder. At the same time, the second filter screen 12 prevents the unshredded scraps from mixing with the shredded scraps, thereby improving the shredding efficiency and quality of the shredder.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
