Technical Field

[0001] This invention relates to the field of copper processing technology, and more specifically to a copper powder collection device. Background Technology

[0002] Currently, straight copper tubes are produced by straightening and sawing large coils in round frames to a certain length using a straightening machine. The sawing process generates a large amount of burrs and copper powder at the ends of these tubes. Currently, the burrs and copper powder are removed by manually blowing compressed air through a soft file onto the inner wall of the tube to remove the powder. This process results in copper powder splattering everywhere and polluting the ground, requiring manual cleaning and collection. This method is not only difficult but also wastes manpower. With increasingly stringent on-site standardization requirements, the above-mentioned copper powder treatment methods are no longer sufficient. Summary of the Invention

[0025] The following will describe in detail the implementation of the present invention with reference to the accompanying drawings and embodiments, so that the process of how the present invention uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] In the description of this invention, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this invention.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature, and in the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0028] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0029] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0030] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0031] As shown in the accompanying drawings, a copper powder collection device includes a purging assembly and a collection assembly. The collection assembly is used to collect copper powder blown from the purging assembly. The collection assembly includes a collection bucket 6 and a dust pressing mechanism.

[0032] The dust pressing mechanism is installed inside the collection bucket 6, and the collection bucket 6 is also equipped with a filter screen 13. The dust pressing mechanism is used to press the dust in the collection bucket 6 onto the filter screen 13.

[0033] In the above solution, compressed air is used to blow copper powder off the inner wall of the straight copper tube. The copper powder flies into the collection component due to inertia, thus realizing the collection of copper powder on the inner wall of the straight copper tube. The collection device effectively solves the problems of copper powder splashing on the inner wall of the straight copper tube, polluting the ground, and being prone to cross-contamination. The device has a good collection effect, improves on-site standardization, and reduces the loss of copper raw materials.

[0034] Meanwhile, to prevent copper powder from mixing with air and flowing out, a filter screen is installed inside the collection bin to intercept copper powder. However, when a certain amount of copper powder is collected, the filter screen becomes clogged due to the accumulated copper powder, affecting the airflow through the filter screen. When the airflow is affected, the ability of the airflow to blow away copper powder weakens, affecting the copper powder collection process. Therefore, the filter screen needs to be cleaned. However, when cleaning the filter screen or collecting copper powder from the filter screen, the collection bin is filled with copper powder and dust. If the top cover of the collection bin is opened at this time, the copper powder and dust inside the collection bin will float out and affect the working environment. Therefore, the top cover should be opened only after the copper powder and dust in the collection bin have settled naturally to reduce pollution. However, the natural settling of copper powder and dust in the collection bin takes a certain amount of time, affecting the overall efficiency. In the above solution, the pressing mechanism can press the dust in the collection bin 6 onto the filter screen 13, which greatly shortens the time for cleaning the filter screen or collecting copper powder from the filter screen, effectively improving efficiency.

[0035] Specifically, such as Figure 2 As shown, the purging assembly includes a workbench 1, a placement box 2, and an air blowing device 7. The placement box 2 is installed on the upper part of the workbench 1 and is used to place the straight copper tubes to be purged. The air blowing device 7 is installed inside the placement box 2. Furthermore, the purging assembly also includes a gathering box 9, which is used to gather the copper powder blown by the air blowing assembly. Even further, the placement box 2 is provided with several fixing grooves 8 that mate with the straight copper tubes, and one end of each fixing groove 8 communicates with the interior of the gathering box 9.

[0036] As another embodiment of the present invention, such as Figure 3 As shown, the dust pressing mechanism includes a piston head 12, a pressing rod 5, and a sealing assembly. The piston head 12 is engaged with the inner ring of the collection bucket 6. The pressing rod 5 is vertically mounted on the piston head 12. One end of the pressing rod 5, away from the piston head 12, extends out of the collection bucket 6. A material passage hole 18 is provided on the piston head 12 at a position corresponding to the feed inlet 21 on the collection bucket 6. The sealing assembly is used to block the material passage hole 18 when the piston head 12 moves downward. Furthermore, the sealing assembly includes a second pressure rod 4 and a sealing plate 14. The first pressure rod 5 is provided with a movable hole that cooperates with the second pressure rod 4. The movable hole is provided with a vertical groove 16 and a horizontal groove 15. The horizontal groove 15 is located at the upper end of the vertical groove 16 and is interconnected. The second pressure rod 4 is provided with a locking rod 17 that cooperates with the vertical groove 16 and the horizontal groove 15. The sealing plate 14 is located at the lower end of the second pressure rod 4. When the locking rod 17 enters the bottom of the horizontal groove 15 from the vertical groove 16, the upper end face of the sealing plate 14 abuts against the lower end face of the material passage hole 18.

[0037] In the above scheme, the normal operating condition of copper powder collection is as follows: Figure 3As shown, the copper powder blown from the purging assembly enters the feed inlet on the upper cover through the connecting pipe, and then enters the collection bucket through the feed hole on the piston head. When it is necessary to clean the filter screen or collect the copper powder on the filter screen, first pull down the second pressure rod upward and then rotate the second pressure rod, so that the locking rod on the second pressure rod enters the bottom of the horizontal groove from the vertical groove. At this time, the upper end face of the sealing plate 14 abuts against the lower end face of the feed hole 18, and the feed hole is blocked. Then, operate the second pressure rod to press down, driving the piston head to move downward. During the downward movement of the piston head, the copper powder is charged. The copper powder and dust in the collection bucket are pressed down until the piston head is about to contact the filter screen. The copper powder and dust in the collection bucket are pressed onto the filter screen. Then, rotate control lever two to remove the blocking plate from blocking the material passage, allowing the airflow on both sides of the piston head to be connected. Then, pull control lever two upward to pull the piston head up. Because the airflow on both sides of the piston head is connected, the piston head will not exert suction on the copper powder on the filter screen when it is running. Therefore, the copper powder on the filter screen will no longer scatter. Then, the cleaning port 22 can be opened to clean the filter screen and collect the copper powder.

[0038] In order to facilitate the operation of the lowering rod, a force-applying rod 3 is provided at the upper end of the lowering rod 4.

[0039] In this embodiment, to prevent copper powder and dust from entering the mating surface between the piston head and the collection bucket during the piston head's downward pressing process and affecting the piston head's operation, a cleaning mechanism for blowing off copper powder from the wall of the collection bucket 6 is also provided on the dust pressing mechanism. Further, the cleaning mechanism includes an air source, an air pipe 20, and several blowing heads 19. The air pipe 20 is installed inside the pressing rod 5 and the piston head 12. Several blowing heads 19 are installed in an inclined annular array at the lower end of the piston head 12. One end of the air pipe 20 is connected to the air source, and the other end is connected to the blowing head 19. Specifically, when the piston head begins to press down, the air source is turned on, and the gas generated by the air source is ejected from the blowing head through the air pipe. Since the blowing head is inclined and points towards the wall of the collection bucket, the gas blown out of the blowing head can blow off the copper powder and dust adhering to the inner wall of the collection bucket, allowing the piston head to press down smoothly.

[0040] In order to prevent the piston head from falling and affecting the normal collection of copper powder during normal operation, an annular magnetic block 11 is provided on the upper end face of the piston head 12. The annular magnetic block 11 can be attracted to the upper cover 10 of the collection bucket 6. During normal operation, the piston head is tightly attached to the upper cover under the action of the annular magnetic block.

[0041] The above description only illustrates the preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. The present invention is not limited to the above embodiments, and variations in its specific structure are permitted. All modifications made within the scope of the independent claims of this invention are also within the scope of protection of this invention.
