Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of copper material cleaning, and particularly relates to a full-automatic copper material brushing device. BACKGROUND

[0002] Copper material has good electrical conductivity, thermal conductivity, corrosion resistance and easy processability, and is widely used in different fields such as industry, electronics, construction and art. However, since copper material is a metal, its surface is prone to rust. In order to ensure the quality of copper parts, an angle grinder is usually used in combination with a steel wire wheel for cleaning in the prior art. However, it should be noted that the rust powder and copper powder generated by the operation of the angle grinder will float in the air. Once the rust powder enters the respiratory tract, it is extremely likely to cause metal fume fever, and long-term exposure can cause chronic copper poisoning. The powder stimulates the skin to cause contact dermatitis, and enters the eyes to cause conjunctivitis or corneal damage. However, in the existing process, only N95 / P2 level masks are used to protect workers, and the ventilation performance of the working environment is increased. However, the rust powder and copper powder still float outside, so this treatment method cannot fundamentally solve the problem. SUMMARY

A collection assembly is arranged on the cleaner. The motor drives the collection assembly to suck the rust powder and copper powder polished by the cleaner into the metal upper accessory through the transmission assembly, and the connection between the metal upper accessory and the collection assembly is located above the protruding part in the metal upper accessory.

[0005] Preferably, the spring telescopic rods are four in total and are arranged in two groups, the two groups of spring telescopic rods are symmetrically arranged on the two sides of the metal upper accessory, and the spring telescopic rods provide upward force to the metal upper accessory.

[0006] Preferably, the metal accessory and the lower mold are respectively composed of two symmetrical metal parts, the two parts of the metal accessory clamp the metal upper accessory, and the two parts of the metal accessory and the metal upper accessory are fastened as a whole by bolts.

[0007] Preferably, the incineration assembly further comprises a sleeve fixed in the metal upper accessory, the sleeve is movably connected with the upper mold, the sleeve is cylindrical, and the reciprocating threaded rod is located in the middle of the sleeve.

[0008] Preferably, the cleaner comprises an intercepting box fixed to the bottom of the protection box, the output shaft of the motor movably penetrates the protection box and the intercepting box, and a steel wire wheel is drivingly connected, the bottom of the steel wire wheel is lower than the bottom of the protection box, the side surface of the protection box is equidistantly provided with supporting rods, and the bottom of each supporting rod is provided with a ball.

[0009] Preferably, the side surface of the intercepting box is inclined; The collection assembly comprises a storage box fixed to the inclined surface of the intercepting box, a fan is rotatably installed in the inside of the storage box, one metal filter plate is installed at the upper and lower ends of the fan in the inside of the storage box, a scraper is movably penetrated through the bottom metal filter plate and installed at the bottom of the fan, the side surface of the storage box is communicated with the metal upper accessory through an air duct, and the top of the storage box is communicated with the side surface of the air duct through equidistantly arranged metal pipes.

[0010] Preferably, the scraper is close to the bottom of the lower metal filter plate, the scraper is composed of a plurality of rubber scraping strips arranged in a ring shape, and the maximum length of the rubber scraping strips can extend to the inside of the air duct.

[0011] Preferably, the top of the fan extends above the storage box. The transmission assembly includes a universal joint that is connected to the top of the fan. The output shaft of the motor is connected to the universal joint via a chain, and the universal joint is connected to a reciprocating threaded rod via a chain.

[0012] Preferably, the incineration assembly further includes a partition installed on the side of the metal accessory, the partition being inserted into the air duct, and the partition having a slot adapted to the connection end of the air duct.

[0013] Preferably, the universal joint is rotatably mounted on the air duct, and corresponding gears are installed on the structure connecting it to chain one and chain two.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the coordinated arrangement of incineration components and other structures, allows the upper mold to descend, with its upper slot aligning with the protruding part of the metal attachment. Dust falls onto the upper mold, and the dust below the upper mold tends to settle. When the lower mold initiates the ignition process, no dust explosion occurs. When the upper mold impacts the calcined dust, it, together with the lower mold, presses the dust into flakes. Any organic matter present, such as grease, dust, or processing residues, will oxidize and decompose into carbon dioxide and water vapor due to high temperature, reducing the weight after forging. Ultimately, the copper content in the calcined material will increase significantly. The batch calcination of copper powder and rust powder allows impurities in both to be burned more thoroughly, and the copper powder can also be heated to a softening state more quickly.

[0015] This invention, through the coordination of structures such as the incineration component, allows the metal attachment to detach from the upper metal attachment when the bolt is removed. Furthermore, the upper and lower molds can be separated into two parts. When copper powder and rust powder are calcined and pressed into flakes, they are highly likely to adhere to the lower mold. Therefore, when the lower mold splits, the adhered flakes of copper may fall off, reducing the time and effort required for workers to reheat the copper with a blowtorch to detach it from the lower mold. The bottom of the upper mold is also fully exposed, allowing for the simultaneous cleaning of any copper powder adhering to it.

[0016] This invention utilizes a combination of transmission and collection components. A motor drives a fan via a chain and universal joint to generate suction. The collection box is mounted on the inclined surface of the interception box, bringing the connection point closer to the wire wheel. This allows for immediate collection of scattered rust powder, preventing excessive dust dispersion. The dust drawn by the fan preferentially adheres to the lower metal filter plate. The scraper rotates synchronously with the fan, scraping the dust off the metal filter plate and causing it to fall to the end of the duct. The airflow generated by the fan enters the side of the duct through a metal pipe, using air pressure to move dust from the bottom of the duct to the interior of the metal accessory, preventing blockage of the metal filter plate and avoiding fan pressure imbalance.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 10 As shown, the present invention provides a fully automatic copper polishing device, including a protective box 1, and further comprising; Motor 3 is installed inside the protective box 1; A cleaner 4, located at the bottom of the protective box 1 and driven by the motor 3, polishes away rust. The incineration assembly 7 is installed inside the protective box 1; The incineration assembly 7 includes a metal upper accessory 71 connected to the protective box 1 via a spring telescopic rod 74. A metal filter plate 712 is installed on the side of the metal upper accessory 71. A reciprocating threaded rod 73 is rotatably installed on the protective box 1. An upper mold 75 is vertically and movably installed inside the metal upper accessory 71. The reciprocating threaded rod 73 is threadedly connected to the upper mold 75. Motor 3 drives reciprocating threaded rod 73 to rotate via transmission assembly 5; The upper mold 75 has four inclined sides, the inner wall of the metal upper accessory 71 has a protruding part, and the side of the upper mold 75 has a groove corresponding to the protruding part. Metal accessory 72 is bolted to the bottom of the upper metal accessory 71. The lower mold 721 is provided inside the metal accessory 72. The middle part of the lower mold 721 is an arc-shaped recess. The bottom of the upper mold 75 is adapted to the recessed part. Flamethrowers 722 with flame-spraying ends facing the recessed part are provided at the four corners of the top of the lower mold 721. Collection component 6 is installed on cleaner 4; The motor 3 drives the collection component 6 through the transmission component 5 to extract the rust powder and copper powder polished by the cleaner 4 into the metal upper attachment 71. The connection between the metal upper attachment 71 and the collection component 6 is located above the protruding part inside the metal upper attachment 71.

[0021] There are four spring telescopic rods 74, and they are arranged in pairs. The two pairs of spring telescopic rods 74 are symmetrically arranged on both sides of the metal upper accessory 71. The spring telescopic rods 74 provide an upward force to the metal upper accessory 71.

[0022] Using the above method: First, place the device on the copper material and start the motor 3, then press and move the device by the handle 2; At this time, the cleaner 4 polishes the copper material, and the motor 3 will also drive the collection component 6 through the transmission component 5 to collect the rust powder and copper powder scattered by the cleaner 4. Finally, the dust enters the interior of the metal upper accessory 71 and falls to the top of the lower mold 721. However, because the middle of the lower mold 721 is concave, the dust will eventually accumulate in the middle of the lower mold 721 due to gravity. Motor 3 will also drive the reciprocating threaded rod 73 to rotate via transmission assembly 5; Since the upper metal accessory 71 is connected to the inside of the protective box 1 via the spring telescopic rod 74, and the upper mold 75 can only move vertically inside the upper metal accessory 71, the reciprocating threaded rod 73 rotates, forcing the upper mold 75 to descend. It should be noted that when the upper mold 75 descends, its slot coincides with the protruding part of the upper metal accessory 71. During this period, the dust continuously entering the upper metal accessory 71 will fall onto the upper mold 75, and the dust below the upper mold 75 will tend to settle and no longer disperse. Therefore, when the lower mold 721 starts the ignition procedure, there will be no dust explosion, further ensuring the safety of the device. The flame of the lower die 721 also heats the dust that has accumulated in the middle of the lower die 721. When the upper die 75 impacts the heated dust, it works with the lower die 721 to press the dust into a sheet. When any organic matter that may be present in the sheet burns, such as grease, dust or processing residue, these organic matter will oxidize and decompose into carbon dioxide and water vapor, which further reduces the weight after forging. The copper content in the final calcined material will be greatly increased, which will reduce the loss of copper material during the rust removal process and save money for subsequent production. When the upper mold 75 rises, the flamethrower 722 immediately stops calcining. When the protruding part of the metal upper accessory 71 is no longer engaged with the groove on the side of the upper mold 75, the dust above the upper mold 75 slides down through its inclined surface. The dust conveyed by the collection component 6 also enters the lower part of the upper mold 75 and waits for the upper mold 75 to press again. The batch calcination of copper powder and rust powder can make the impurities in both burn more thoroughly, and the copper powder can also heat up to a softened state more quickly. Once the rust is removed, the bolts on the metal fitting 72 can be disassembled, and the calcined material on the lower mold 721 can be removed without generating excessive dust. This greatly reduces the risk of workers contracting dust-related illnesses and effectively protects their health.

[0023] Depend on Figure 9As can be seen, the length of the reciprocating thread on the reciprocating threaded rod 73 limits the distance that the upper mold 75 can descend, and the upper mold 75 will not touch the flamethrower 722, thus avoiding the flamethrower 722 being squeezed and damaged. In addition, the side of the metal upper accessory 71 is provided with a metal filter plate 712, which can prevent dust from drifting outwards while also obtaining the oxygen required for the flamethrower 722 to burn. The heat generated by the burning will not remain inside the metal upper accessory 71, thus preventing the entire device from overheating and burning the staff. When there is a lot of calcined dust on the lower mold 721, the gap between the top of the lower mold 721 and the bottom of the upper mold 75 will increase. Since the length of the reciprocating thread groove on the reciprocating thread rod 73 is fixed, when the above situation occurs, the reciprocating thread rod 73 forces the upper mold 75 to descend to the farthest distance, and the upper metal accessory 71 and the metal accessory 72 at the bottom will descend. However, the spring telescopic rod 74 will still maintain the force that pushes the upper metal accessory 71 upward, so that the upper mold 75 can descend and cooperate well with the lower mold 721 to press the dust.

[0024] like Figures 7-10 As shown, the metal attachment 72 and the lower mold 721 are each composed of two symmetrical metal parts. The upper metal attachment 71 is clamped between the two parts of the metal attachment 72, and the two parts of the metal attachment 72 and the upper metal attachment 71 are fastened together by bolts.

[0025] Using the above scheme: As can be seen from the figure, the bottom of the upper metal accessory 71 extends to the middle of the metal accessory 72, and the upper metal accessory 71 and the two parts constituting the metal accessory 72 are fastened together by bolts. When the bolt is removed, the metal attachment 72 will not only detach from the upper metal attachment 71, but it and the lower mold 721 can also be separated into two parts. That is, the metal attachment 72 is separated into two independent parts, and the lower mold 721 is also separated into two independent components. When copper powder and rust powder are calcined and stamped into sheets, they are very likely to stick to the lower mold 721. Therefore, when the lower mold 721 is separated, the sheet copper material that is stuck to it may fall off, thereby reducing the time and effort of the workers to reheat the copper material with a blowtorch to make it fall off the lower mold 721. It should also be noted that the bottom of the upper mold 75 will be fully exposed, and the copper powder adhering to it can be cleaned at the same time.

[0026] like Figures 7-10 As shown, the incineration assembly 7 also includes a sleeve 751 fixed inside the metal upper accessory 71. The sleeve 751 is movably engaged with the upper mold 75. The sleeve 751 is cylindrical and the reciprocating threaded rod 73 is located in the middle of the sleeve 751.

[0027] By adopting the above solution: when dust is transported into the metal upper accessory 71, the sleeve 751 will prevent it from contacting the reciprocating threaded rod 73, thereby avoiding dust from entering the thread groove and causing excessive wear, which effectively extends the service life of the device, and at the same time makes the fit between the reciprocating threaded rod 73 and the upper mold 75 more precise.

[0028] like Figures 1-5 As shown, the cleaner 4 includes an interceptor box 41 fixed to the bottom of the protective box 1. The output shaft of the motor 3 moves through the protective box 1 and the interceptor box 41 and is connected to a wire wheel 42. The bottom of the wire wheel 42 is lower than the bottom of the protective box 1. Support rods 11 are installed at equal intervals on the side of the protective box 1, and ball bearings 12 are installed at the bottom of each support rod 11.

[0029] Using the above solution: when the output shaft of motor 3 drives the wire wheel 42 to rotate and polish the rust, the interception box 41 can effectively prevent the dust from drifting outwards excessively, and the collection component 6 can also pick up the dust in the first place. As the operator presses the device and moves it for cleaning, the ball bearing 12 rolls against the copper material, which prevents the bottom of the metal accessory 72 from touching the copper material and scratching it. This design also reduces the effort required for the operator to maintain the balance of the wire wheel 42, making the device easier and more convenient to operate.

[0030] like Figures 1-5 and Figure 7 As shown, the top of the fan 63 extends above the storage box 61; The transmission assembly 5 includes a universal joint 51 that is connected to the top of the fan 63. The output shaft of the motor 3 is connected to the universal joint 51 via a chain 1 52. The universal joint 51 is connected to the reciprocating threaded rod 73 via a chain 2 53.

[0031] The sides of the interceptor box 41 are slanted. The collection component 6 includes a storage box 61 fixed to the inclined surface of the interception box 41. A fan 63 is rotatably installed inside the storage box 61. A metal filter plate 64 is installed at both the upper and lower ends of the fan 63 inside the storage box 61. The bottom of the fan 63 moves through the lower metal filter plate 64 and is equipped with a scraper 631. The side of the storage box 61 is connected to the metal upper accessory 71 through the air duct 62. The top of the storage box 61 is connected to the side of the air duct 62 through equidistantly arranged metal pipes.

[0032] The scraper 631 is attached to the bottom of the lower metal filter plate 64. The scraper 631 is composed of several circumferentially arrayed rubber scrapers, and the maximum length of the scraper can extend into the interior of the air duct 62.

[0033] Using the above solution: when the output shaft of motor 3 drives the wire wheel 42 to rotate and grind the rust, the output shaft of motor 3 will also drive the universal joint 51 to rotate through chain 52. The universal joint 51 will drive the fan 63 to generate suction and collect the rust powder and copper powder ground by the wire wheel 42. It should be noted that the collection box 61 is installed on the inclined surface of the interception box 41, which makes the connection between the two closer to the wire wheel 42, so that the scattered rust powder can be collected in the first place and the excessive dust can be avoided. Dust drawn in by fan 63 preferentially adheres to the lower metal filter plate 64, but due to Figure 4 as well as Figure 5 As can be seen, the scraper 631 rotates synchronously with the fan 63, so the scraper 631 will scrape the dust on the metal filter plate 64, causing the dust to fall to the end of the air duct 62. The air generated by the rotation of fan 63 enters the side of air duct 62 through metal pipe, thereby using air pressure to carry the dust at the bottom of air duct 62 to the interior of metal accessory 71 and put the incineration assembly 7 into working state, without causing the dust to affect fan 63 and cause unnecessary damage to its surface.

[0034] like Figures 1-10 As shown, the incineration assembly 7 also includes a partition 711 installed on the side of the metal accessory 71. The partition 711 is inserted into the air duct 62 and has a slot that matches the connection end of the air duct 62.

[0035] The above solution will be adopted; priority will be given to reviewing [the information]. Figure 9 When the reciprocating threaded rod 73 drives the upper mold 75 to descend, the slot on the upper mold 75 will first overlap with the protrusion on the inner wall of the metal upper accessory 71, thereby preventing dust from continuously entering below the upper mold 75 and preventing dust explosion. When the copper material that has been calcined and stamped into sheets on the lower mold 721 is thick enough, the upper mold 75 descends to the farthest distance, and the metal upper accessory 71 will also descend. The slot on the partition plate 711 will no longer overlap with the connection of the air duct 62, and dust will no longer be able to enter the interior of the metal upper accessory 71, thus avoiding excessive dust accumulation above the upper mold 75. Therefore, when the upper mold 75 is at its highest point, the dust will not enter the area below the upper mold 75 in large quantities at once, resulting in excessive dust covering the already sheet-like copper material. Consequently, the flamethrower 722 cannot effectively calcine the sheet-like copper material and the dust at the same time, leading to incomplete combustion of impurities in the sheet-like copper material.

[0036] like Figures 1-5 As shown, the universal joint 51 is rotatably mounted on the air duct 62, and corresponding gears are installed on the structure that connects to chain one 52 and chain two 53.

[0037] The above solution is adopted: during the normal grinding process, the speed of the wire wheel 42 should not be lower than 1500 RPM, and the smaller the wheel diameter, the higher the speed needs to be. Similarly, if the fan 63 needs to generate wind power, it also needs a high speed. Therefore, in order to ensure the synchronization of the two operations, the design of chain 52 and gear is adopted, which can better reduce the slippage of the power transmission components during operation.

[0038] Working principle and usage process of this invention: When the motor 3 drives the wire wheel 42 to rotate and polish the rust, its output shaft also drives the fan 63 to rotate through the chain 52 and the universal joint 51 to generate suction and collect the rust powder and copper powder polished by the wire wheel 42. Dust preferentially adheres to the lower metal filter plate 64. The scraper 631 rotates synchronously with the fan 63 and scrapes the dust on the metal filter plate 64, causing the dust to fall to the end of the air duct 62. The air generated by the rotation of fan 63 enters the side of air duct 62 through metal pipe, thereby using air pressure to carry the dust at the bottom of air duct 62 to the inside of metal upper accessory 71 and fall onto the top of lower mold 721. Because the lower mold 721 has a concave center, the dust will eventually accumulate in the center of the lower mold 721 due to gravity. Universal joint 51 drives reciprocating threaded rod 73 to rotate via chain 2 53, forcing upper mold 75 to descend; The flame in the lower mold 721 heats the dust that has accumulated in the middle of the lower mold 721. When the upper mold 75 impacts the heated dust, it works with the lower mold 721 to press the dust into a sheet shape. When the upper mold 75 rises, the flamethrower 722 immediately stops firing. When the protruding part of the metal upper accessory 71 is no longer engaged with the groove on the side of the upper mold 75, the dust above the upper mold 75 slides down through its inclined surface. The dust conveyed by the collection component 6 also enters the lower part of the upper mold 75 and waits for the upper mold 75 to perform the next stamping operation. Once the rust has been removed, the bolts on the metal fitting 72 can be disassembled, and the calcined material on the lower mold 721 can be removed.

[0039] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
