Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy automotive parts manufacturing technology, and in particular to an aluminum chip screening device. Background Technology

[0002] In the production of aluminum alloy automotive parts, machining processes are typically required to obtain finished parts that meet dimensional and appearance standards. During machining operations, byproducts such as aluminum chips and aluminum blocks are generated and transported via chip conveyors and augers to designated locations for unified recycling and remelting. In actual production, the aluminum chips discharged from the machine tools are granular. However, due to factors such as machining processes or tool wear and aging, turning operations often generate a large amount of strip-shaped and clump-shaped aluminum chips. These chips easily become entangled on the augers during transport, affecting their conveying efficiency and even causing blockages, leading to transmission interruptions, increased equipment maintenance costs, and disruptions to continuous and stable production operations.

[0003] Therefore, developing an aluminum chip screening device for practical production is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide an aluminum chip screening device to address the above-mentioned problems, thereby solving the problem that strip-shaped aluminum chips easily become entangled in the conveying auger during the aluminum chip recycling process of existing machining operations, affecting the conveying efficiency and causing blockage of the chip conveyor.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An aluminum chip screening device includes a screening roller conveyor, with a conveyor auger connected below the screening roller conveyor. The screening roller conveyor includes several parallel and spaced rollers, with the spacing between adjacent rollers corresponding to the granular aluminum chips, so that the granular aluminum chips can leak into the conveyor auger below through the gaps between the rollers.

[0007] Preferably, the output end of the screening roller conveyor is provided with a collection box for collecting strip-shaped aluminum chips and clump-shaped aluminum chips transported by the screening roller conveyor.

[0008] Preferably, a cleaning rake is provided corresponding to the screening roller conveyor. The cleaning rake is connected to a telescopic cylinder, which can drive the cleaning rake to perform reciprocating motion on the screening roller conveyor to forcibly clean the strip-shaped and clump-shaped aluminum chips accumulated on the screening roller conveyor and between the roller bars.

[0009] Preferably, the cleaning rake includes a rake body with rake teeth spaced apart. The rake body is located on the back side of the screening roller track, and the rake teeth pass through the gap between the rollers from bottom to top and extend out of the screening roller track to a certain height.

[0010] Preferably, a guide rod is provided on the screening roller conveyor corresponding to the rake body, and the rake body is slidably connected to the guide rod. The guide rod can support and guide the rake body to ensure the stability of the cleaning rake's movement.

[0011] Preferably, the screening roller conveyor is inclined, so that the strip-shaped and clump-shaped aluminum chips falling on the rollers can automatically slide into the collection box by their own gravity.

[0012] The beneficial effects of this invention are as follows: By setting up a screening roller conveyor to screen and recycle mixed aluminum chips, this invention can effectively intercept strip-shaped and clump-shaped aluminum chips from entering the conveyor auger, avoiding the problems of strip-shaped and clump-shaped aluminum chips entangled in the conveyor auger, affecting conveying efficiency, and easily causing conveyor auger blockage failures. It also reduces equipment maintenance costs and ensures continuous and stable production. The screening roller conveyor keeps the strip-shaped and clump-shaped aluminum chips isolated on the rollers in a dynamic and tumbling motion, which facilitates the shaking off of granular aluminum chips attached to the strip-shaped and clump-shaped aluminum chips, making the screening more thorough.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-3As shown, an aluminum shavings screening device includes a screening roller conveyor 10. A conveyor auger is connected below the screening roller conveyor 10. The screening roller conveyor 10 includes several parallel and spaced rollers 11. The spacing between adjacent rollers 11 corresponds to the size of the granular aluminum shavings, allowing the granular aluminum shavings to leak through the gaps in the rollers 11 into the conveyor auger below for normal transport and recycling. Simultaneously, strip-shaped and clump-shaped aluminum shavings are isolated on the roller conveyor and transported to a designated recycling position by the conveyor action of the screening roller conveyor 10. In use, the input end of the screening roller conveyor 10 is connected to a chip conveyor. The mixed aluminum shavings discharged from the chip conveyor enter the screening roller conveyor 10, where the granular aluminum shavings are screened and recycled from the strip-shaped and clump-shaped aluminum shavings.

[0020] This embodiment effectively intercepts strip-shaped and clump-shaped aluminum chips from entering the conveyor auger, preventing them from entangled and affecting conveying efficiency, thus avoiding auger blockage. It also reduces equipment maintenance costs and ensures continuous and stable production. The screening roller conveyor 10 keeps the strip-shaped and clump-shaped aluminum chips isolated on the rollers 11 in a dynamic, tumbling motion, which facilitates the dislodging of granular aluminum chips attached to them, resulting in more thorough screening.

[0021] Preferably, the output end of the screening roller conveyor 10 is provided with a collection box 20 for collecting strip-shaped aluminum chips and clump-shaped aluminum chips transmitted by the screening roller conveyor 10, so as to facilitate the centralized processing of strip-shaped aluminum chips and clump-shaped aluminum chips.

[0022] Preferably, a cleaning rake 30 is provided corresponding to the screening roller conveyor 10 to clean up strip-shaped and clump-shaped aluminum chips accumulated on the screening roller conveyor 10 and between the roller bars 11. The cleaning rake 30 is connected to a telescopic cylinder 31, which can drive the cleaning rake 30 to perform reciprocating motion on the screening roller conveyor 10. This forces the cleaning of strip-shaped and clump-shaped aluminum chips that fail to move with the screening roller conveyor 10 in time, preventing them from clogging the gaps between the roller bars 11 and affecting the normal falling of granular aluminum chips, thus ensuring screening efficiency.

[0023] Preferably, such as Figure 2 As shown, the cleaning rake 30 includes a rake body 32 with rake teeth 33 spaced apart on the rake body 32. The rake body 32 is located on the back side of the screening roller conveyor 10, and the rake teeth 33 pass through the gap between the roller bars 11 from bottom to top and extend out of the screening roller conveyor 10 to a certain height.

[0024] Preferably, a guide rod 34 is provided on the screening roller conveyor 10 corresponding to the rake body 32. The rake body 32 is slidably connected to the guide rod 34. When the rake body 32 reciprocates, the guide rod 34 can support and guide the rake body 32, ensuring the stability of the cleaning rake 30's movement.

[0025] Preferably, such as Figure 3As shown, the screening roller conveyor 10 is inclined, allowing strip-shaped and clump-shaped aluminum chips falling onto the rollers 11 to automatically slide into the collection box 20 under their own gravity, reducing the cleaning frequency of the cleaning rake 30 and improving screening efficiency. Preferably, baffles are provided around the screening roller conveyor 10 to prevent aluminum chips from falling everywhere.

[0026] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
