Description

Technical Field

[0001] This utility model relates to the field of copper powder grinding technology, and in particular to a copper powder grinding anti-clogging discharge pipe. Background Technology

[0002] For example, Chinese patent CN212791305U discloses an anti-clogging component for a copper powder grinding device. When the copper powder is ground into fine powder, an electric push rod retracts the slider, and the fine powder falls from the bottom of the grinding disc into the funnel. The sliding mechanism set in the funnel can accelerate the flow rate of the fine copper powder, and at the same time avoid the clogging problem caused by a large amount of fine copper powder falling into the funnel at the same time, which can ensure smooth production and improve production efficiency.

[0003] In the aforementioned application, during the discharge process, an electric push rod pulls the slider to retract and discharge the ground copper powder in one go. During this process, a large amount of copper powder falling may block the discharge pipe. The flow of copper powder driven by the up-and-down movement of the toothed plate is slow. Moreover, the chemical properties of copper powder determine that it contains a certain amount of moisture. If the moisture content is high and causes the copper powder to clump together, the up-and-down movement of the toothed plate may not be able to drive the flow of copper powder, and the discharge pipe may still be blocked. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a copper powder grinding anti-clogging discharge pipe, which solves the technical problem that existing technologies rely solely on the up-and-down movement of the toothed plate to drive the flow of copper powder. When copper powder with high moisture content clumps together, it cannot be discharged quickly and will still clog the discharge pipe. This invention achieves the goal of preventing copper powder from clogging the discharge pipe.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a copper powder grinding anti-clogging discharge pipe, including a discharge pipe installed at the bottom of the grinding box, wherein the discharge pipe is provided with an anti-clogging mechanism to prevent copper powder from accumulating and clogging the discharge pipe, and the grinding box is provided with a grinding mechanism for crushing and grinding the copper powder.

Both the driving bevel gear and the driven bevel gear are installed inside the gear box. A rotating shaft is rotatably connected to a rotating hole at the bottom of the gear box on the driven bevel gear. A feeding auger is installed on the rotating shaft to convey and discharge copper powder from the discharge pipe.

[0008] Preferably, the crushing assembly includes a crushing chamber located on the right side inside the grinding box and communicating with the grinding chamber. Two symmetrical crushing shafts located in the crushing chamber are rotatably connected to the right side of the grinding box, and crushing blade sets are installed alternately on the two crushing shafts.

[0025] 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.

[0026] Example 1

[0027] Current technologies rely solely on the up-and-down movement of the toothed plate to flow copper powder. However, when copper powder with high moisture content clumps together, it cannot be quickly discharged, leading to blockage of the discharge pipe. This embodiment provides a copper powder grinding anti-clogging discharge pipe. Please refer to... Figures 1-6 This embodiment provides a copper powder grinding anti-clogging discharge pipe, which can prevent copper powder from clogging the discharge pipe. The copper powder grinding anti-clogging discharge pipe includes a discharge pipe 2 installed at the bottom of the grinding box 1. The discharge pipe 2 is provided with an anti-clogging mechanism 3 to prevent copper powder from accumulating and clogging the discharge pipe 2. The grinding box 1 is provided with a grinding mechanism 4 for crushing and grinding copper powder. The grinding mechanism 4 crushes and grinds the copper block into copper powder, which is then discharged from the discharge pipe 2. The anti-clogging mechanism 3 in the discharge pipe 2 twists and conveys the copper powder out, preventing the copper powder from clogging the discharge pipe 2.

[0028] Because existing technology relies solely on the up-and-down movement of the toothed plate to drive the flow of copper powder, it cannot quickly discharge copper powder when the copper powder with high moisture content clumps together, and will still clog the discharge pipe. Therefore, this device is equipped with an anti-clogging mechanism 3. The anti-clogging mechanism 3 includes a gear box 31 installed at the top center of the discharge pipe 2 via a support rod. A rotating shaft 32 is rotatably connected inside the grinding box 1, passing through the discharge pipe 2 and the gear box 31. A driving bevel gear 33 is installed on the rotating shaft 32, and a driven bevel gear 34 is meshed on the driving bevel gear 33. Both the driving bevel gear 33 and the driven bevel gear 34 are... Installed inside the gearbox 31, the driven bevel gear 34 is fitted with a rotating shaft 35 rotatably connected to a rotating hole at the bottom of the gearbox 31. The rotating shaft 35 is fitted with a feeding auger 36 that feeds copper powder out of the discharge pipe 2. When discharging, the rotating shaft 32 is rotated, which in turn drives the driving bevel gear 33 to rotate, thereby driving the driven bevel gear 34 that meshes with it to rotate. This, in turn, drives the rotating shaft 35 and the feeding auger 36 on it to rotate and feed the copper powder out of the discharge pipe 2. The discharge efficiency is higher, and there is no fear of copper powder agglomerating and clogging the discharge pipe 2.

[0029] To grind the copper block into powder, the device is equipped with a grinding mechanism 4, which includes a grinding chamber 40 inside the grinding box 1. A grinding shaft 41 located inside the grinding chamber 40 is rotatably connected to the grinding box 1. A grinding roller 42 is mounted on the grinding shaft 41. A feeding channel 43 is opened at the bottom of the grinding chamber 40. A grinding base plate 44 is installed on the top of the feeding channel 43. Electric ear plates 45 are installed on both sides of the grinding base plate 44. Guide optical shafts 46 are installed in guide grooves opened on the inner walls of the front and rear sides of the feeding channel 43, and the electric ear plates 45 are slidably connected to the guide optical shafts. On the right side of the grinding box 1, there is a crushing component 47 for pre-processing copper blocks. In the feeding channel 43, there is a feeding component 48 for assisting in the feeding of copper powder. The grinding shaft 41 is driven to rotate by an external power source, which in turn drives the grinding roller 42 in the grinding chamber 40 to rotate. Together with the grinding base plate 44, the copper blocks are crushed into powder. After the copper powder is crushed, the electric ear plate 45 is driven to slide to the right along the guide groove on the guide shaft 46, thereby extruding the feeding channel 43. The copper powder flows into the discharge pipe 2 through the feeding channel 43, completing the grinding and feeding of copper powder.

[0030] To prevent copper powder from clogging the feeding channel 43 as it falls through, the device is also equipped with a feeding assembly 48. The feeding assembly 48 includes a guide ramp 481 that is symmetrically and inclinedly installed in the feeding channel 43. Rotating grooves 482 are symmetrically opened on the front and rear sides of the bottom of the grinding box 1. Flexible springs 483 located in the rotating grooves 482 are installed on the front and rear sides of the rotating shaft 32. Rubber balls 484 are installed on the outer ends of the flexible springs 483. When the rotating shaft 32 is rotated, the flexible springs 483 on the rotating shaft 32 are simultaneously driven to rotate in the rotating grooves 482. The rubber balls 484 at the other end of the rotating shaft 32 impact the guide ramp 481, thereby preventing copper powder from accumulating on the guide ramp 481.

[0031] A turntable 51 is installed at the front end of the rotating shaft 32, and a dustproof box 52 is installed at the bottom of the rotating groove 482. When rotating the rotating shaft 32, the turntable 51 can be rotated directly, which is more labor-saving and convenient. The dustproof box 52 prevents dust from entering the interior of the grinding box 1 through the rotating groove 482 and contaminating the copper powder.

[0032] Example 2

[0033] Based on Example 1, such as Figures 1-6As shown, since large copper blocks are not convenient to be directly crushed and ground, the device is equipped with a crushing component 47 to pre-treat the copper blocks. The crushing component 47 includes a crushing chamber 471 located on the right side inside the grinding box 1 and connected to the grinding chamber 40. Two crushing shafts 472 symmetrically located inside the crushing chamber 471 are rotatably connected to the right side of the grinding box 1, and crushing blade sets 473 are installed alternately on the two crushing shafts 472. Side wall blade sets 474 are installed alternately on the inner walls of both sides of the crushing chamber 471. The rear end of the crushing shafts 472 is meshed with a meshing gear 475. The rotation of the crushing shafts 472 drives the meshing gears 475 to rotate, thereby driving the two sets of crushing blade sets 473 to rotate alternately, crushing the copper blocks. In conjunction with the side wall blade sets 474 on the crushing chamber 471, it prevents copper blocks from being missed from the side walls, thus comprehensively crushing the copper blocks into small fragments, which are convenient for crushing and grinding.

[0034] Pulleys 476 are symmetrically installed at the rear end of the grinding shaft 41 and the rear end of one of the crushing shafts 472. The two pulleys 476 are connected by a transmission belt 477. When the grinding shaft 41 rotates, the transmission belt 477 in the pulley 476 drives the crushing shaft 472 to rotate. The copper block is crushed and ground by a single power source, which is more energy-efficient and environmentally friendly.
