[0002] A metal debris briquetting machine is a device used to cold-press cast iron chips, steel chips, and copper chips into cylindrical or other-shaped briquettes. It is mainly used to directly cold-press cast iron chips, steel chips, copper chips, aluminum chips, high-quality ore powder, cast iron chips, and steel chips into cylindrical or other-shaped briquettes weighing 3 - 6 kilograms, so as to facilitate storage and transportation and reduce the losses during transportation and smelting in the process of recycling and reuse.

[0003] The feeding device of a metal debris briquetting machine usually uses a screw conveyor for feeding. Since the spiral blades of the screw conveyor are made of metal, when the spiral blades convey metal debris to the briquetting machine, due to the friction between metals, local spiral blades will be worn. When replacing the spiral blades, the entire screw conveyor needs to be disassembled to replace the entire spiral blade, causing the non-worn spiral blades to be replaced together, resulting in a more complex process for replacing the spiral blades and being unable to replace the spiral blades locally.

[0024] The following further describes the embodiments of the present utility model in detail in conjunction with the drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0025] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7, a feeding system for a metal scrap briquetting machine, including the briquetting machine body 1. A storage hopper 2 is fixed at the upper end of the briquetting machine body 1. The storage hopper 2 is in a frustum shape, and the storage hopper 2 is used to hold metal scraps. At the same time, the storage hopper 2 is set to be frustum-shaped with a large upper part and a small lower part and the side surface is an inclined surface. When metal scraps are placed in the storage hopper 2, the metal scraps will fall downward under the influence of the inclined surface, which is convenient for feeding the metal scraps into the briquetting component 7 inside the briquetting machine body 1 for briquetting. An outlet 3 is opened at the front end of the briquetting machine body 1. An outlet hopper 4 is provided between the briquetting component 7 and the briquetting machine body 1. The outlet hopper 4 is in a frustum shape and is fixed on the briquetting machine body 1. The outlet hopper 4 is connected to the outlet 3. The outlet hopper 4 is also set to be frustum-shaped. After the metal scraps are briquetted, the briquetting component 7 pushes the briquetted metal scraps to the outlet hopper 4. Under the action of the inclined surface of the outlet hopper 4, the briquetted metal scraps will directly slide out from the inclined surface of the outlet hopper 4 and the outlet 3. A transmission component 8 is provided inside the briquetting machine body 1. A briquetting component 7 connected to the briquetting machine body 1 is provided at the lower end of the storage hopper 2. A feeding cylinder 61 is provided at the rear end of the storage hopper 2. A longitudinal feeding component 6 is located inside the feeding cylinder 61. The feeding cylinder 61 is connected to the briquetting component 7. The transmission component 8 provides a power source. The feeding cylinder 61 feeds the metal scraps into the briquetting component 7. The briquetting component 7 applies pressure to the metal scraps to form them into a cake shape, achieving the effect of briquetting.

[0026] Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5, a transverse feeding component 5 rotatably connected in a symmetric manner is provided inside the storage hopper 2, and a longitudinal feeding component 6 perpendicular to the transverse feeding component 5 is rotatably connected inside the storage hopper 2. By symmetrically arranging the two transverse feeding components 5 and vertically providing the longitudinal feeding component 6 therebetween, it effectively prevents metal debris materials from remaining in the storage hopper 2 and can fully feed the materials into the pressing cylinder 71, improving the feeding efficiency. Spiral blades 54 are respectively installed on the transverse feeding component 5 and the longitudinal feeding component 6. The spiral blades 54 are spirally wound around the transverse feeding component 5 and the longitudinal feeding component 6, thereby forming spiral feeding blades. The transverse feeding component 5 includes a transmission shaft 51. One end of the transmission shaft 51 is fixed with a transmission wheel 52. The fixing plate 53 is rotatably connected to the transmission shaft 51, and the fixing plate 53 is fixed on the storage hopper 2. Two rows of staggered positioning shafts 56 are fixed along the axis of the outer part of the transmission shaft 51. The positioning holes 541 correspond to the positioning shafts 56 to insert the spiral blades 54 therein. At the same time, the spiral blades 54 are fixedly connected through the connecting pieces 55 and the positioning shafts 56 to prevent the spiral feeding blades from sliding when the transverse feeding component 5 rotates for feeding. The spiral blades 54 are located on the outer wall of the transmission shaft 51. One end of the spiral blade 54 is fixed with a connecting piece 55, and the other end of the spiral blade 54 is fixed with a fixing hole 542. The inner wall of the spiral blade 54 is provided with positioning holes 541 corresponding to the positioning shafts 56. There are multiple spiral blades 54, and they are connected end to end through the connecting pieces 55. The connecting pieces 55 are detachably connected with the positioning shafts 56. The multiple spiral blades 54 are connected end to end through the connecting pieces 55 and the positioning shafts 56 to form a complete spiral feeding blade. After long-term feeding, when a local spiral blade 54 is damaged, only the connecting pieces 55 and the positioning shafts 56 on both sides of it need to be disassembled, pulled out from the positioning shafts 56, and a new spiral blade 54 is installed to achieve local replacement. One end of the positioning shaft 56 is semi-circular and faces the feeding direction. One end of the positioning shaft 56 is set to be semi-circular and faces the feeding direction, reducing the friction between the debris and the positioning shaft 56 and extending its service life. The multiple spiral blades 54 are connected end to end through the connecting pieces 55 and the positioning shafts 56 to form spiral feeding blades.

[0027] Please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7The cam 72 is fixed to the inner wall of the cam 71 and the cam 73 is fixed to the inner wall of the cam 71 so that the cam 73 can be pressed downwards to release the pressure of the cam 72. Then the hydraulic rod 72 continues to extend, pushing the cake-shaped metal debris into the discharge hopper 4 and sliding it out from the inclined surface of the discharge hopper 4. The transmission assembly 8 includes a dual-axis reduction motor 81 and a commutator 82 fixed on the cake press body 1. One end of the dual-axis reduction motor 81 is transmission-connected to the longitudinal feeding assembly 6, and the other end of the dual-axis reduction motor 81 is transmission-connected to the input end of the commutator 82 through a universal joint. The output end of the commutator 82 is transmission-connected to the transmission shaft 51 of the transverse feeding assembly 5. The dual-axis reduction motor 81 is transmitted to the longitudinal feeding assembly 6 in the form of a chain or belt. The dual-axis reduction motor 81 is connected to the input end of the commutator 82 through a universal joint, so that the dual-axis reduction motor 81 and the commutator 82 can also be transmitted when tilted. The commutator 82 is transmitted to the transmission wheel 52 of the transverse feeding assembly 5 in the form of a chain or belt, thereby driving the transverse feeding assembly 5 to work.

[0028] When using this utility model:

[0029] First, pour the metal scraps into the storage hopper 2, and start the dual-axis reduction motor 81 to work. Since the dual-axis reduction motor 81 is connected to the longitudinal feeding assembly 6 and the commutator 82, and the commutator 82 is connected to the transverse feeding assembly 5, the dual-axis reduction motor 81 drives the longitudinal feeding assembly 6 and the transverse feeding assembly 5 to work and feed the metal scraps in the storage hopper 2 into the pressing cylinder 71;

[0030] Then, the hydraulic rod 72 works, and the hydraulic rod 72 presses the cake-pressing block 73 to compress the metal debris. Due to the blocking effect of the block 76 on the metal debris, the metal debris in the pressing cylinder 71 is finally formed into a cake shape.

[0031] Then, the telescopic rod 75 is retracted, the stopper 76 is removed, and then the hydraulic rod 72 continues to extend, pushing the cake-shaped metal chips into the discharge hopper 4, and sliding out from the inclined surface of the discharge hopper 4;

[0032] Finally, after long-term use, when the spiral blade 54 is worn, it is only necessary to disassemble the connecting parts 55 and the positioning shaft 56 on both sides thereof, pull out the spiral blade 54 from the positioning shaft 56, and install a new spiral blade 54 to realize the replacement of the local spiral blade 54.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
