DETAILED DESCRIPTION

[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 in conjunction with the accompanying drawings and embodiments.

[0040] like Figures 1 to 11 As shown, the present invention provides a sponge breaking device, including 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 at the lower part of the adjusting shaft 11. A plurality of cutting knife units 14 are arranged at equal intervals above the first mounting seat 13. The cutting knife unit 14 includes a fixing seat 141 and three cutting knives 142. The fixing seat 141 is fixed on the adjusting shaft 11. The inner end of the cutting knife 142 is mounted on the fixing seat 141 through a first rotating shaft 143. The first rotating shaft 143 is fixed on the cutting knife 142. The first rotating shaft 143 is rotatable on the fixing seat 141. A gear 144 is fixed at the bottom of the first rotating shaft 143. The inner end of the rotating shaft 12 A plurality of groups of ring teeth 15 are fixedly provided on the wall, and the gear 144 is meshed with the ring teeth 15. The inner ends of the three cutters 142 are equidistantly distributed in a ring shape on the fixed seat 141, that is, the three first rotating shafts 143 are equidistantly distributed in a ring shape on the fixed seat 141. The interior of the rotating shaft 12 is hollow and a second mounting seat 16 is fixed to the bottom thereof. A plurality of groups of third arc holes 17 are provided on the rotating shaft 12. The adjusting shaft 11 is inserted into the interior of the rotating shaft 12 and the rotating shaft 12 is extended out from the bottom. 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 adjusting shaft 11 is rotated. Since the gear 144 is meshed with the ring gear 15, the gear 144 will rotate accordingly during the rotation of the adjusting 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, and the cutting circumference of the outer end of the cutter 142 changes. The distance between two adjacent cutters 142 on the same cutter unit 14 also changes. The sponge sizes cut by different cutter 142 positions are not the same. Therefore, different sponge sizes can be cut by changing the cutting circumference of the cutter 142 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 adjusting shaft 11 and the rotating shaft 12 are relatively fixed, and the position of the cutter 142 is fixed and will not move.

[0043] The rotating shaft 12 can cover the rotating parts such as the gear 144 to prevent these parts from directly contacting the material and reduce dust accumulation. Although dust can enter the rotating shaft 12 through the third arc hole 17, the amount of dust entering the rotating shaft 12 is limited by controlling the height of the third arc hole 17. In addition, 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 and the drive motor. The drive motor can be fixed on a frame, etc. In order to increase the stability of the adjustment shaft 11 during rotation, the bottom of the adjustment shaft 11 can be installed on the frame through a bearing.

Since the second screening drum 35 and the first screening drum 31 are fixed together, the second screening drum 35 will also rotate 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.
