[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Specific examples are given below.

[0034] Please see Figure 1 - Figure 6This utility model provides a metal chip cleaning device for thin aluminum profile processing, including a slide rail 1; a second fixing plate 3 is fixedly connected to the side wall of the slide rail 1; a first support arm 31 is fixedly connected to the side wall of the second fixing plate 3; a first fixing bolt 32 is fixedly connected to the end of the first support arm 31; a second support arm 33 is fixedly connected to the side wall of the first fixing bolt 32; a second fixing bolt 34 is fixedly connected to the end of the second support arm 33; a slider 35 is fixedly connected to the side wall of the second fixing bolt 34; a second sliding groove 36 is opened on the side wall of the slider 35; a sliding rod 37 is fixedly connected between the second sliding grooves 36; a counterweight 38 is fixedly connected to the side wall of the sliding rod 37; a pressing block 39 is fixedly connected to the end of the counterweight 38; a pair of first sliding grooves 101 are opened on the side wall of the slide rail 1; a second motor 102 is fixedly connected to the side wall of the slide rail 1; during operation, the second motor 102... 2. The second fixing plate 3 is rotated. At this time, the pair of first support arms 31 fixed to the side wall of the second fixing plate 3 rotate simultaneously. The rotation of the pair of first support arms 31 will drive the pair of second support arms 33 fixed to the end of the pair of first fixing bolts 32 to rotate. When the second support arms 33 rotate, they will drive the pair of sliders 35 fixed to the side wall of the pair of second fixing bolts 34 to slide between the pair of first slide grooves 101. At this time, the slide rod 37 can move between the pair of second slide grooves 36 opened on the pair of sliders 35. When the slide rod 37 moves, it will drive the pressing block 39 fixed to the end of the counterweight block 38 to move up and down. This step can use the up and down moving pressing block 39 to press down the metal chips on the surface of the slide 1, which improves the portability when recycling metal chips later and reduces the safety hazards of manual cleaning and collection.

[0035] Furthermore, such as Figure 5 As shown, a second rod 12 is fixedly connected to the side wall of the slide 1; a pair of telescopic cylinders 13 are fixedly connected to the side wall of the second rod 12; a pair of telescopic rods 14 are connected to the ends of the pair of telescopic cylinders 13; a first rod 11 is fixedly connected to the ends of the pair of telescopic rods 14; a pair of first fixed rods 15 are fixedly connected to the ends of the first rod 11; pulleys 16 are fixedly connected to the ends of the pair of first fixed rods 15; a pair of first motors 17 are fixedly connected to the side wall of the slide 1; during operation, the pair of first motors 17 can drive the pair of telescopic rods 14 fixed to the ends of the pair of telescopic cylinders 13 to extend and retract; at this time, the pair of telescopic cylinders 13 can be rotated through the second rod 12, which can tilt the slide 1 to the required angle; in addition, the first rod 11 fixed to the ends of the pair of telescopic rods 14 can drive the pulleys 16 fixed through the first fixed rod 15 to move; this step can move the entire machine to the required placement position, and the tilted slide 1 can allow metal chips to slide off.

[0036] Furthermore, such as Figure 1 and Figure 2As shown, a first fixing plate 2 is fixedly connected to the side wall of the slide 1; a second guide pipe 21 is fixedly connected to the side wall of the first fixing plate 2; a first guide pipe 22 is fixedly connected to the end of the second guide pipe 21; a conical barrel 23 is fixedly connected to the end of the first guide pipe 22; a third motor 103 is fixedly connected to the side wall of the slide 1; the conical barrel 23 is made of rubber. During operation, the second guide pipe 21 is activated by starting the third motor 103, which then exerts suction force. This suction force passes through the second guide pipe 21 and the first guide pipe 22 to reach the conical barrel 23. Because the conical barrel 23 is conical, this step effectively collects splashed metal shavings. Furthermore, because the conical barrel 23 is made of rubber, it reduces scratches caused by metal shavings on the parts, extending the service life of the parts.

[0037] Furthermore, such as Figure 3 As shown, a second fixing plate 4 is fixedly connected to the side wall of the second fixing rod 3; multiple bases 41 are fixedly connected to the side wall of the second fixing plate 4; multiple brushes 42 are fixedly connected to the side walls of the multiple bases 41; a second motor 102 is fixedly connected to the side wall of the slide rail 1; the second motor 102 is fixedly connected to the end of the second fixing rod 3; during operation, the second fixing rod 3 is rotated by starting the second motor 102, at which time the second fixing plate 4 fixed to the side wall of the second fixing rod 3 can drive the multiple brushes 42 fixed to the multiple bases 41 to rotate; this step can effectively clean the metal shavings on the slide rail 1 and reduce the accumulation of metal shavings on the surface of the slide rail 1.

[0038] Furthermore, such as Figure 4 As shown, a pair of first connecting rods 5 are fixedly connected to the side wall of the slide rod 37; a second connecting rod 51 is fixedly connected to the end of the pair of first connecting rods 5; a pair of support rods 52 are fixedly connected to the end of the second connecting rod 51; a filter plate 53 is fixedly connected between the pair of support rods 52; multiple filter holes 54 are opened on the side wall of the filter plate 53; a spring 55 is fixedly connected to the side wall of the filter plate 53; during operation, the movement of the slide rod 37 can drive the pair of first connecting rods 5 to move simultaneously, and at this time, the second connecting rod 51 fixed to the end of the pair of first connecting rods 5 can drive the filter plate 53 fixed between the pair of support rods 52 to move synchronously; this step can reduce the accumulation of metal shavings on the surface of the filter plate 53, because the multiple filter holes 54 on the side wall of the filter plate 53 can more easily collect the metal shavings filtered by the filter plate 53; at the same time, when the filter plate 53 moves, the spring 55 can limit the filter plate 53 to keep it stable and reduce its multi-angle shaking.

[0039] Furthermore, such as Figure 1 and Figure 2As shown, multiple nozzles 61 are fixedly connected to the side wall of the second guide pipe 21; a water storage pipe 6 is fixedly connected to the end of the multiple nozzles 61; and a water inlet pipe 62 is fixedly connected to the side wall of the water storage pipe 6. During operation, water is stored in the water storage pipe 6 through the external water inlet pipe 62, and water can be sprayed through the multiple nozzles 61 fixed to the side wall of the water storage pipe 6. This step can moisten the metal shavings that slide down from the second guide pipe 21, reducing the possibility of combustion caused by high temperature and excessive accumulation of metal shavings.

[0040] Furthermore, such as Figure 5 and Figure 6 As shown, a pair of fixing blocks 18 are fixed to the side wall of the slide rail 1; multiple fixing teeth 19 are fixed to the side wall of the pair of fixing blocks 18; a fixing seat 7 is fixed to the end of the telescopic rod 14; a fixing groove 71 is opened on the side wall of the fixing seat 7; a third fixing bolt 72 is fixed to the side wall of the fixing seat 7; a gear 73 is fixed to the side wall of the third fixing bolt 72; multiple gear teeth 74 are fixed to the side wall of the gear 73; a sliding plate 75 is fixed to the side wall of the telescopic cylinder 13; multiple sliding plate teeth 76 are fixed to the side wall of the sliding plate 75; a triangular block 77 is fixed to the end of the sliding plate 75; during operation, the extension of the telescopic rod 14 simultaneously drives the fixing seat 7 to move, at which time the third fixing bolt 79 fixed to the side wall of the fixing seat 7 moves. Bolt 72 can drive gear 73 to rotate in fixed groove 71, and gear teeth 74 fixed on gear 73 rotate synchronously; since gear teeth 74 and slide plate teeth 76 engage with each other, they will synchronously drive slide plate 75 to move. At this time, triangular block 77 fixed to the end of slide plate 75 will also move synchronously; at this time, triangular block 77 can be fixed to different fixed teeth 19 according to the extension and retraction length of telescopic rod 14; this step can change the fixed position of triangular block 77 and fixed teeth 19 by telescopic rod 14 extension and retraction, and at the same time, the engagement of gear teeth 74 and slide plate teeth 76 can limit telescopic rod 14, so that when slide 1 is tilted, telescopic cylinder 13 and telescopic rod 14 will not move due to pulley 16, making the overall device more stable.

[0041] Working principle: During operation, the second motor 102 drives the second fixed rod 3 to rotate. Simultaneously, the pair of first support arms 31 fixed to the side wall of the second fixed rod 3 rotate. This rotation of the first support arms 31 drives the pair of second support arms 33 fixed to the ends of the pair of first fixing bolts 32 to rotate. The rotation of the second support arms 33 causes the pair of sliders 35 fixed to the side walls of the pair of second fixing bolts 34 to slide between a pair of first sliding grooves 101. At this time, the sliding rod 37 can move between a pair of second sliding grooves 36 formed on the pair of sliders 35. The movement of the sliding rod 37 causes the pressing block 39 fixed to the end of the counterweight 38 to move up and down. This step can utilize... The vertically moving crushing block 39 crushes the metal shavings on the surface of the slide 1, improving the portability of the metal shavings during later recycling and reducing the inefficiency of manual collection. A pair of motors 17 can extend and retract a pair of telescopic rods 14 fixed to the ends of a pair of telescopic cylinders 13. At this time, the pair of telescopic cylinders 13 can be rotated via rod 12, tilting the slide 1 to the desired angle. Additionally, rod 11 fixed to the ends of the pair of telescopic rods 14 can move the pulley 16 fixed via rod 15. This step moves the entire machine to the desired location, allowing the tilted slide 1 to allow the metal shavings to slide off. Starting motor 103 causes the guide pipe 21 to draw in the metal shavings. When the suction works, the suction can reach the conical barrel 23 through the second guide pipe 21 and the first guide pipe 22. Because the conical barrel 23 is conical, it can effectively collect splashed metal shavings. Furthermore, because the conical barrel 23 is made of rubber, it reduces scratches caused by metal shavings on parts, extending their service life. By starting the second motor 102, the second fixing rod 3 rotates. At this time, the second fixing plate 4, fixed to the side wall of the second fixing rod 3, can drive the multiple brushes 42 fixed to the multiple bases 41 to rotate. This step effectively cleans the metal shavings on the slide rail 1, reducing the accumulation of metal shavings on the surface of the slide rail 1. The movement of the slide rod 37 can drive the simultaneous movement of a pair of first connecting rods 5. The second connecting rod 51 at the end of the first connecting rod 5 can drive the filter plate 53, which is fixed between a pair of support rods 52, to move synchronously. This step can reduce the accumulation of metal shavings on the surface of the filter plate 53, because the filter plate 53 has multiple filter holes 54 on its side wall, which can more easily collect the metal shavings filtered by the filter plate 53. At the same time, when the filter plate 53 moves, the spring 55 can limit the filter plate 53 to keep it stable and reduce its multi-angle shaking. Water is stored in the water storage pipe 6 through the external water inlet pipe 62. At this time, water can be sprayed through multiple spray pipes 61 fixed to the side wall of the water storage pipe 6. This step can wet the metal shavings that slide down from the second guide pipe 21, reducing the possibility of combustion caused by high temperature and excessive accumulation of metal shavings.The extension of the telescopic rod 14 simultaneously moves the fixed base 7. At this time, the No. 3 fixing bolt 72, fixed to the side wall of the fixed base 7, drives the gear 73 to rotate within the fixing groove 71. The gear teeth 74, fixed to the gear 73, rotate synchronously. Because the gear teeth 74 and the sliding plate teeth 76 engage with each other, they synchronously drive the sliding plate 75 to move. The triangular block 77, fixed to the end of the sliding plate 75, will also move synchronously. Depending on the extension and retraction length of the telescopic rod 14, the triangular block 77 can be fixed to different fixing teeth 19. This step can change the fixed position of the triangular block 77 and the fixing teeth 19 through the extension and retraction of the telescopic rod 14. Simultaneously, the engagement of the gear teeth 74 and the sliding plate teeth 76 limits the telescopic rod 14, preventing the telescopic cylinder 13 and the telescopic rod 14 from moving due to the pulley 16 when the slide rail 1 is tilted, thus making the overall device more stable.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
