[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the invention more clearly understood, the invention is further described below with reference to the accompanying drawings and embodiments.

[0040] like Figures 1 to 11 As shown, the present invention provides a sponge breaking device, which includes a breaking component 10, a driving component 20, a screening component 30 and an outer cylinder 40.

[0041] refer to Figure 1 and Figure 2The crushing assembly 10 includes an adjusting shaft 11 and a rotating shaft 12. A first mounting seat 13 is fixed to the lower part of the adjusting shaft 11. A plurality of cutting knife units 14 are equidistantly arranged above the first mounting seat 13 on the adjusting shaft 11. The cutting knife unit 14 includes a fixing seat 141 and three cutters 142. The fixing seat 141 is fixed to the adjusting shaft 11. The inner end of the cutter 142 is mounted on the fixing seat 141 through a first rotating shaft 143. The first rotating shaft 143 is fixed to the cutter 142. The first rotating shaft 143 is rotatable on the fixing seat 141. A gear 144 is fixed to the bottom of the first rotating shaft 143. The inner end of the rotating shaft 12 Multiple sets of ring teeth 15 are fixed to the wall, and the gear 144 is engaged with the ring teeth 15. The inner ends of the three cutters 142 are distributed in a circular and equidistant manner on the fixed seat 141, that is, the three first rotating shafts 143 are distributed in a circular and equidistant manner on the fixed seat 141. The interior of the rotating shaft 12 is hollow and a second mounting seat 16 is fixed to its bottom. Multiple sets of third arc holes 17 are provided on the rotating shaft 12, and the adjusting shaft 11 is inserted into the interior of the rotating shaft 12 and the bottom extends out of the rotating shaft 12. The outer end of the cutter 142 passes through the third arc hole 17 and extends out of the rotating shaft 12. The first mounting seat 13 is provided under the second mounting seat 16 and the two are fixed together by a locking member.

[0042] When the first mounting seat 13 and the second mounting seat 16 are released, the adjustment shaft 11 is rotated. Since the gear 144 meshes with the ring gear 15, the gear 144 rotates accordingly during the rotation of the adjustment shaft 11, thereby driving the first rotating shaft 143 to rotate. The first rotating shaft 143 then drives the inner end of the cutter 142 to rotate, changing the cutting circumference of the outer end of the cutter 142. The distance between two adjacent cutters 142 on the same cutter unit 14 also changes. Different cutter 142 positions can cut different sponge sizes. Therefore, by changing the cutting circumference of the cutter 142, different sponge sizes can be cut to meet different sofa filling requirements. When the first mounting seat 13 and the second mounting seat 16 are fixed together, the positions of the adjustment shaft 11 and the rotating shaft 12 are relatively fixed, and the cutter 142 is fixed and does not move.

[0043] The rotating shaft 12 can cover the rotating parts such as the gear 144, preventing these parts from directly contacting the material and reducing dust accumulation. Although dust can enter the rotating shaft 12 through the third arc-shaped hole 17, the amount of dust entering the rotating shaft 12 is limited by controlling the height of the third arc-shaped hole 17. Moreover, during the cutting process, the rotating parts in the rotating shaft 12 are fixed, so the dust entering will not affect the normal cutting of the material. Figure 2 , the cutter 142 itself has a certain curvature.

[0044] refer to Figure 3The drive assembly 20 is used to drive the adjustment shaft 11 to rotate; the drive assembly 20 includes a drive motor and a coupling. The coupling connects the adjustment shaft 11 to the drive motor. The drive motor can be fixed to a frame, etc. To increase the stability of the adjustment shaft 11 during rotation, the bottom of the adjustment shaft 11 can be mounted on the frame via a bearing. The screening assembly 30 is mounted outside the crushing assembly 10 and has a feed port 33 at its top for screening materials. The outer cylinder 40 is mounted outside the screening assembly 30 in a fixed position and has a second discharge port 42 at its bottom.

[0046] The first screening drum 31 rotates together with the rotating shaft 12. Since the second screening drum 35 and the first screening drum 31 are fixed together, the second screening drum 35 also rotates together with the first screening drum 31. The material enters the first screening drum 31 from the feed port 33 and is cut by the crushing assembly 10. Under the rotation of the cutter 142 and the first screening drum 31, the material that meets the first sieve hole 32 passes through the first screening drum 31 and enters between the first screening drum 31 and the second screening drum 35. The first discharge port 38 is blocked for a certain period of time, and the material that meets the second sieve hole 36 passes through the second screening drum 35. Then the first discharge port 38 is opened, and the material is finally discharged from the first discharge port 38 or the second discharge port 42.

A second material guide cylinder 313 is fixed to the bottom of the outer cylinder 40. The second material guide cylinder 313 includes a first cylinder wall 3131 and a second cylinder wall 3132. The first cylinder wall 3131 is fixed to the bottom of the outer cylinder 40. The first cylinder wall 3131 and the second cylinder wall 3132 are fixedly connected by a plurality of connecting rods 3133. A second discharge channel 314 (see arrow A) is formed between the first cylinder wall 3131 and the second cylinder wall 3132. The second discharge channel 314 communicates with the second discharge port 42. A first discharge channel 315 (see arrow B) is formed between the second cylinder wall 3132 and the first material guide cylinder 312. The first discharge channel 315 communicates with the first discharge port 38. Both the first discharge channel 315 and the second discharge channel 314 are provided with a collection port, and the materials are ultimately collected separately.

The bottom opening of the conical guide member 50 is located directly above the feed inlet 33, and the bottom of the conical guide member 50 does not contact the feed inlet 33. The conical guide member 50 is fixed in position and can be fixed to a frame, etc., and is not movable. The material is fed into the feed inlet 33 by the conical guide member 50.

[0055] refer to Figure 6 and Figure 7A plurality of guide rods 316 are fixed to the end of the first screening drum 31. The guide rods 316 are perpendicular to the height direction of the first screening drum 31 and are arranged equidistantly along the end of the first screening drum 31. A plurality of guide grooves 317 are formed at the end of the second screening drum 35. The guide rods 316 are inserted into the guide grooves 317. The guide rods 316 and guide grooves 317 further secure the first screening drum 31 and the second screening drum 35.

[0056] refer to Figures 6-11 , first flanges 318 are fixed at both ends of the first screening drum 31, and the guide rod 316 is fixed on the first flange 318. A first adjusting drum 319 is provided on the outer shell of the first screening drum 31, and a first long hole 320 is opened on the first adjusting drum 319.

When the first flange 318 and the second flange 321 are released, the first adjusting drum 319 can rotate relative to the first screening drum 31. At different rotational positions of the first adjusting drum 319, the degree of blockage of the first sieve hole 32 is different, and the effective aperture of the first sieve hole 32 is also different. By adjusting the relative position of the first adjusting drum 319 and the first screening drum 31, the effective aperture of the first sieve hole 32 is adjusted to meet the requirements of different material sizes.

[0057] The first material guiding cylinder 312 is fixed under the first adjusting cylinder 319 .

[0058] Similarly, by adjusting the relative positions of the second adjusting cylinder 323 and the second screening cylinder 35, the effective aperture of the second sieve hole 36 can be adjusted.

[0059] The first flange 318 is provided with a plurality of first arcuate holes 326, and the second flange 321 is fixed with a plurality of first guide blocks 327. The first guide blocks 327 are inserted into the first arcuate holes 326. The arc length of the first arcuate holes 326 is no greater than the aperture of the first sieve hole 32. After the positions of the first adjustment cylinder 319 and the first sieve cylinder 31 are determined, a plurality of fasteners, i.e., bolts, are sequentially passed through the first arcuate holes 326 and screwed into the threaded holes 328 on one side of the first guide blocks 327. The nuts of the bolts contact the first flange 318 outside the first arcuate holes 326, thereby securing the first flange 318 to the second flange 321. Specifically, the threaded holes 328 are provided on both sides of the first guide block 327, close to the first guide block 327. When screwing in the bolts, the threaded holes 328 are selected according to the requirements.
