Description

Technical Field

[0001] This utility model relates to the field of waste recycling technology, specifically to a cemented carbide waste recycling device. Background Technology

[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals and binder metals through powder metallurgy. It possesses a series of excellent properties, including high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. Cemented carbide is widely used as a cutting tool material, such as turning tools and milling cutters, for cutting cast iron, graphite, glass, stone, and ordinary steel. It can also be used to cut difficult-to-machine materials such as heat-resistant steel, stainless steel, and tool steel, making it widely applicable. During the machining of cemented carbide parts, a considerable amount of waste chips and scraps are generated. Since these still have some value, a cemented carbide waste chip recycling device is typically used to collect them after machining.

[0003] Chinese patent document CN211678080U discloses a cemented carbide waste recycling device. In use, the motor is started, and then the waste is poured into the first screening chamber and sequentially passed through the first, second, and third screening chambers, which improves the quality of the alloy. After that, the waste falls into the shredding chamber, where it is shredded. The shredded waste then falls into the collection box. The shredding process changes the size of the alloy, making it easier to collect and improving the utilization rate of the collection space.

[0004] The existing technology has the following problems:

[0005] In the aforementioned cemented carbide scrap recycling device, when the scrap is screened through an inclined screen plate, the screen holes on the screen plate are easily blocked because the inclined screen plate and the screen chamber are fixedly installed, which reduces the filtration and separation efficiency of the scrap. Furthermore, the shredded scrap falls into the collection box through the second discharge port. During the discharge process, the scrap attached to the inner wall of the shredder is not discharged, resulting in incomplete unloading of the alloy scrap. Utility Model Content

[0006] This invention provides a cemented carbide scrap recycling device to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

Shredding rollers are fixedly installed on the outer surface of the rotating shafts. Gears are fixedly installed on the outer side of the rotating shafts located outside the shredding box. The opposite sides of the two gears mesh with each other, and a motor is fixedly installed at the rear end of the right rotating shaft.

[0011] Preferably, the diameter of the filter holes in the three sieve plates decreases sequentially from top to bottom.

[0012] Preferably, the inner cavity of the recycling bin has limiting grooves on both the left and right sides, and the end of the sieve plate is located inside the limiting groove.

[0013] Preferably, a baffle frame is fixedly installed on the upper surface of the sieve plate, and the baffle frame is U-shaped.

[0014] Preferably, the front side of the swing arm has a straight groove, and the inner cavity of the straight groove is slidably connected to the outer surface of the slide rod.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figures 1-8 As shown, a cemented carbide scrap recycling device includes a recycling box 1, a shredding box 2 fixedly installed at the bottom of the recycling box 1, a shredding assembly 8 rotatably connected to the inner cavity of the shredding box 2, three screening assemblies 7 rotatably connected to the inner cavity of the recycling box 1, inclined discharge shells 4 fixedly installed on both the left and right sides of the recycling box 1, an inclined discharge shell 5 fixedly installed on the right side of the shredding box 2, and a feed pipe 3 fixedly installed on the top of the recycling box 1. The screening assembly 7 includes a rotating shaft 71, the rear end of which is rotatably connected to the rear side of the inner cavity of the recycling box 1, and the front end extending to the outside of the recycling box 1. A screen plate 74 is fixedly installed on the outer surface of the rotating shaft 71, and a swing arm 7 is fixedly installed on the front end of the rotating shaft 71. 2. An L-shaped support plate 10 is fixedly installed on the front side of the recycling box 1. A motor 76 is fixedly installed on the upper surface of the top of the L-shaped support plate 10. A disc 73 is fixedly installed at the output end of the motor 76. A slide rod 77 is fixedly installed on the front side of the disc 73. The shredding assembly 8 includes two rotating shafts 81. The front ends of the two rotating shafts 81 are rotatably connected to the front side of the inner cavity of the shredding box 2, and the rear ends of the rotating shafts 81 extend to the rear side of the shredding box 2. A shredding roller 82 is fixedly installed on the outer surface of the rotating shafts 81. A gear 84 is fixedly installed on the outer side of the rotating shafts 81 at the position outside the shredding box 2. The opposite sides of the two gears 84 mesh with each other, and a motor 83 is fixedly installed at the rear end of the right rotating shaft 81.

[0031] In use, connect motor 2 (83) and motor 1 (76) to the power supply. Feed cemented carbide scrap into the recycling bin 1 through the feed pipe 3. Motor 1 (76) drives the disc 73 and slide bar 77 to rotate. The slide bar 77 drives the swing arm 72 to swing, which in turn drives the screen plate 74 to swing left and right through the rotating shaft 1 (71) to screen the cemented carbide scrap, preventing clogging of the filter holes on the screen plate 74. By setting three screen plates 74, multiple screening and filtration of the scrap are achieved, improving the filtration effect. Impurities are discharged from the recycling bin 1 through the discharge shell 1 (4). The screened alloy scrap enters the shredding bin 2 through the bottom of the recycling bin 1. Motor 2 (83) drives the rotating shaft 2 (81) to rotate, which in turn drives the gear 84 to rotate. The meshing of the two gears 84 drives the two shredding rollers 82 to shred the screened alloy scrap. This eliminates the need for belt drive to operate the shredding rollers, thus avoiding slippage.

[0032] like Figures 3-6 As shown, the diameter of the filter holes in the three sieve plates 74 decreases sequentially from top to bottom.

[0033] By setting three sieve plates 74, multiple screening and filtration of waste chips are achieved, thereby improving the filtration effect.

[0034] like Figure 3 , Figure 4 As shown, limiting grooves 11 are provided on both the left and right sides of the inner cavity of the recycling box 1, and the end of the sieve plate 74 is located inside the limiting groove 11.

[0035] The limiting groove 11 restricts the end of the screen plate 74, providing space for the screen plate 74 to swing. When the screen plate 74 swings, the left and right sides of the recycling box 1 are prevented from interfering with the movement of its end.

[0036] like Figures 3-6 As shown, a baffle frame 75 is fixedly installed on the upper surface of the sieve plate 74, and the baffle frame 75 is U-shaped.

[0037] The baffle frame 75 is set to block impurities on the sieve plate 74.

[0038] like Figure 3 , Figure 5 , Figure 6 As shown, a straight groove 78 is provided on the front side of the swing arm 72, and the inner cavity of the straight groove 78 is slidably connected to the outer surface of the slide rod 77.

[0039] The sliding action between the slide rod 77 and the straight groove 78 can limit the rotation of the rotating shaft 71, causing the screen plate 74 to swing left and right.

[0040] like Figure 2 , Figure 3 , Figure 7 , Figure 8 As shown, a bracket 9 is fixedly installed on the rear side of the shredder box 2, and the motor 83 is fixedly installed on the bracket 9.

[0041] Bracket 9 is provided to assist in supporting motor 2 83 and to provide an installation position for motor 2 83.

[0042] like Figures 3-6 As shown, an electric push rod 6 is fixedly installed on the left side of the shredder box 2, and a discharge plate 12 is fixedly installed at the output end of the electric push rod 6. The outer side of the discharge plate 12 is slidably connected to the inner cavity of the shredder box 2.

[0043] The electric push rod 6 pushes the unloading plate 12 to the left, pushing the shredded alloy in the shredding box 2 into the discharge shell 5 for discharge, ensuring thorough unloading and preventing a small amount of alloy waste from adhering to the inner wall of the shredding box 2.

[0044] The working principle of this utility model is as follows: In use, the electric push rod 6, motor 83, and motor 76 are connected to the power supply. Hard alloy scrap is fed into the recycling bin 1 through the feed pipe 3. Motor 76 drives the disc 73 and slide rod 77 to rotate, and the slide rod 77 drives the swing arm 72 to swing. This, in turn, drives the screen plate 74 to swing left and right through the rotating shaft 71, screening the hard alloy scrap and preventing clogging of the filter holes on the screen plate 74. By setting three screen plates 74 with different filter hole diameters, multiple screening and filtration of the scrap are achieved, improving the filtration effect. The limiting groove 11 restricts the end of the screen plate 74, and impurities are discharged from the recycling bin through the discharge shell 4. 1. A baffle frame 75 is set up to block impurities. The alloy waste after screening will enter the shredding box 2 through the bottom of the recycling box 1. The motor 83 drives the rotating shaft 81 to rotate, and the rotating shaft 81 drives the gear 84 to rotate. The meshing of the two gears 84 drives the two shredding rollers 82 to rotate to shred the alloy waste after screening. There is no need to use belt drive to drive the shredding rollers, thus avoiding slippage. The electric push rod 6 pushes the discharge plate 12 to the left, pushing the shredded alloy in the shredding box 2 into the discharge shell 5 for discharge. The discharge is thorough, preventing a small amount of alloy waste from adhering to the inner wall of the shredding box 2.

[0045] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
