Technical Field

[0001] The utility model relates to the technical field of aluminum alloy automobile parts, in particular to an automatic aluminum scrap sorting device. Background Art

[0002] During the production process of aluminum alloy automobile parts, it is necessary to use a sawing machine to remove the pouring risers formed during the casting process of the casting. During the sawing operation, the block-shaped risers, aluminum slag and aluminum chips produced by cutting will fall into the recycling box together. Due to the different recycling processes of block-shaped risers, aluminum slag and scattered aluminum chips, the risers and aluminum chips need to be sorted and processed during recycling. The existing sorting method is usually manual sorting, and the operator needs to manually search in the recycling box to separate the risers, aluminum slag and aluminum chips. This sorting method has high labor intensity, low operating efficiency, and incomplete sorting, which affects the subsequent processing of risers, aluminum slag and aluminum chips.

[0003] Based on this, developing an automatic aluminum chip sorting device for application in actual production is an urgent problem to be solved. Utility Model Content

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] like Figure 1As shown, an automatic sorting device for aluminum chips includes a drum 1 for sorting risers of castings. The two ends of the drum 1 are open structures, serving as a feeding end 11 and a discharging end 12 for aluminum chips and risers of castings, respectively. Screening holes 13 are provided on the outer wall of the drum 1. The aperture of the screening hole 13 corresponds to the size of the aluminum chips and the risers of castings, so that the aluminum chips passing through the drum 1 can pass through the screening hole 13 smoothly, while the risers cannot pass through the screening hole 13, thereby realizing the screening and separation of aluminum chips and risers of castings. The drum 1 is tilted, and the feeding end 11 of the drum 1 is higher than the discharging end 12, so as to realize the automatic rolling down of the risers of castings. One end of the drum 1 is connected to a driving motor 2 to provide rotational power for the rotation and screening of the drum 1.

[0022] When in use, the drive motor 2 starts to drive the drum 1 to rotate. The feeding end 11 of the drum 1 corresponds to the sawing machine setting. The waste generated by the sawing machine cutting the riser will automatically enter the drum 1 through the feeding end 11. The waste mixed with the riser, aluminum chips and aluminum slag will be screened by the rotating drum 1. The aluminum chips and other small-sized cutting waste will leak out of the drum 1 through the screening hole 13, while the larger-sized aluminum slag and risers will be isolated in the drum 1, realizing the automatic screening of the riser and aluminum chips. The rotating and tilted setting of the drum 1 will make the casting riser isolated in the drum 1 automatically roll down along the tilt direction of the drum 1, and be discharged from the drum 1 through the discharge end 12, completing the automatic sorting of aluminum chips and casting risers. This embodiment realizes the automatic sorting of aluminum chips and risers, eliminates the manual sorting operation mode, reduces the labor intensity of the operators, improves the sorting efficiency, and eliminates the problem of incomplete sorting and affecting recycling.

[0023] Preferably, a support roller 3 is provided corresponding to the drum 1, and the support roller 3 is rollingly connected to the drum 1 to support the drum 1 and ensure the stability of the drum 1 during rotation. Preferably, a support roller 3 is provided corresponding to both the feeding end 11 and the discharging end 12 of the drum 1.

[0024] As a preferred embodiment, an aluminum chip box 4 is provided on the outer wall of the drum 1 to receive small-sized waste materials such as aluminum chips discharged from the screening holes 13 of the drum 1, so as to facilitate the collection and processing of the sorted materials. Furthermore, a riser box 5 is provided at the discharge end 12 of the drum 1 to collect large-sized waste materials such as risers and aluminum slag discharged from the discharge end 12 of the drum 1. The provision of the aluminum chip box 4 and the riser box 5 realizes the automatic recovery of aluminum chips and aluminum slag, and reduces the labor intensity of the operators.

[0025] Preferably, the diameter of the feeding end 11 of the drum 1 is larger than the diameter of the discharging end 12, so that the drum 1 has a conical structure. The drum 1 with a conical structure has a larger caliber at the feeding end 11, which is convenient for receiving waste. The larger feeding end 11 facilitates the waste to enter the drum 1 in a dispersed form, thereby improving the waste screening efficiency. In addition, the smaller discharging end 12 facilitates the centralized collection of larger-sized waste such as risers and aluminum slag, thereby avoiding the problem that the risers and aluminum slag are thrown out at high speed when the drum 1 rotates and is discharged, and cannot accurately fall into the riser box 5.

[0026] As a preferred embodiment, the sorting device further includes an anti-blocking structure provided in correspondence with the drum 1, which is used for unblocking the screening holes 13 of the drum 1, and timely eliminating the problem of blocking the screening holes 13 caused by aluminum slag stuck, aluminum chips accumulated, etc., to ensure the sorting effect. Specifically, the anti-blocking structure includes a scraper 6 provided in correspondence with the outer wall of the drum 1, and the scraper 6 is in sliding contact with the outer wall of the drum 1. During the rotation of the drum 1, the riser, aluminum slag and aluminum chips stuck in the screening holes 13 and exposed from the drum wall are scraped off, which plays a role in unblocking the screening holes 13, and ensures the operating efficiency and sorting effect of the sorting device.

[0027] Furthermore, the scraper 6 is retractably connected to the frame 8 through the telescopic mechanism 7. When the drum 1 operates normally and the screening effect is good, the telescopic mechanism 7 retracts, driving the scraper 6 away from the outer wall of the drum 1, and does not interfere with the normal sorting operation. When the screening hole 13 is blocked to a certain extent, the telescopic mechanism 7 pushes out and drives the scraper 6 to stick to the outer wall of the drum 1 to perform the dredging operation of the screening hole 13. The telescopic mechanism 7 can use an existing structure that can realize telescopic action, such as an electric push rod or a pneumatic push rod.

[0028] Preferably, in order to avoid the scraper 6 from being in rigid contact with the outer wall of the drum 1 during the dredging operation of the screening holes 13, which affects the operating stability and service life of the sorting device, the scraper 6 is elastically connected to the telescopic mechanism 7 through a spring. When performing the dredging operation, the scraper 6 will achieve floating contact with the outer wall of the drum 1 through the spring, improving the problems of poor operating stability and short service life caused by rigid contact.

[0029] The above disclosure is only a specific embodiment of the present invention, but the present invention is not limited thereto. For ordinary technicians in this field, without departing from the principle of the present invention, any deformation made should be regarded as belonging to the protection of the present invention.
