[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] The following is combined with Figure 1-6 , describes in detail the technical solution provided by the embodiments of the present invention.

[0035] As attached Figure 1-3 As shown, an embodiment of the present invention provides a reverse copper extruder cleaning device with cleaning and lubrication functions, the device comprising: a first cleaning rod 1, a cleaning pad 2, a second cleaning rod 3 and an end cover 4, wherein:

[0036] The first cleaning rod 1 is provided with a first through hole 10 along the axial direction. The first cleaning rod 1 is arranged in the extrusion cylinder of the reverse copper extruder, and the outer wall of the first cleaning rod 1 is gap-matched with the inner wall of the extrusion cylinder; the cleaning pad 2 is arranged at the end of one end of the first cleaning rod 1, and the outer periphery of the cleaning pad 2 is gap-matched with the inner wall of the extrusion cylinder. The cleaning pad 2 is arranged as a split structure, including a detachably connected first cleaning pad 20 and a second cleaning pad 21. A second through hole 201 is arranged on the first cleaning pad 20. The first cleaning pad 20 is fixedly connected to the first cleaning rod 1, and the first through hole 10 on the first cleaning rod 1 is aligned with the second through hole 201 on the first cleaning pad 20; the second cleaning rod 3 is arranged as a hollow pipe The structure is as follows: the second cleaning rod 3 is arranged in the first through hole 10 on the first cleaning rod 1, and the outer wall of the second cleaning rod 3 is gap-matched with the inner wall of the first through hole 10; the end cover 4 is fixedly connected to the other end of the first cleaning rod 1, and a lubricating liquid pipeline 41 connected to the external lubricating liquid and a compressed air pipeline 40 connected to the external compressed air are arranged on the end cover 4, and the lubricating liquid pipeline 41 is sealedly connected to the first through hole 10 on the first cleaning rod 1, and the air compression pipeline is sealedly connected to the annular channel formed by the first cleaning rod 1 and the second cleaning rod 3, so that the compressed air in the air compression pipeline can purge the debris in the extrusion cylinder and lubricate the inner wall of the extrusion cylinder through the lubricating liquid in the lubrication pipeline.

[0037] Specifically, by setting the first cleaning rod 1 to match the gap with the inner wall of the extrusion barrel, the first cleaning rod 1 and the cleaning pad 2, the second cleaning rod 3 and the end cover 4 driven by it can be convenient to move in the inner wall of the extrusion barrel; by setting the outer periphery of the cleaning pad 2 to match the gap with the inner wall of the extrusion barrel, the large particles of impurities in the extrusion barrel can be scraped and cleaned by the second cleaning pad 21, and the fine impurities and firmly attached impurities can be cleaned again by blowing, so that the impurities and debris in the extrusion barrel are fully cleaned, and at the same time, the lubricating medium sprayed out of the lubricating fluid pipeline 41 can be avoided when the device of the present invention is cleaning; by setting the second cleaning rod 3 in the first through hole 10 of the first cleaning rod 1 and setting it to match the gap, the pipeline of the second cleaning rod 3 and the gap between the first cleaning rod 1 and the second cleaning rod 3 form a double-channel structure, which can make the overall structure of the present invention simple and reduce the weight of the overall device of the present invention; by setting the cleaning pad 2 as a split structure, it is convenient to replace and repair it, thereby ensuring the effect of cleaning, blowing and lubricating the extrusion barrel.

[0038] Therefore, the reverse copper extruder cleaning device with cleaning and lubrication functions of the present invention can integrate the three functions of cleaning, purging and lubricating the extrusion barrel together by respectively passing the lubricating liquid and compressed air into the second cleaning rod 3 and the first cleaning rod 1 through the lubricating liquid pipeline 41 and the compressed air pipeline 40, and blowing and lubricating the inner wall of the extrusion barrel at the position of the split cleaning pad 2. The three processes are completed simultaneously without adding additional actions, and the working efficiency of the whole machine is not affected. The problem of low efficiency of manual cleaning, purging and lubrication of the extrusion barrel is solved. At the same time, the above-mentioned device of the present invention can realize the operation of automatic cleaning, purging and lubricating the inner wall of the extrusion barrel, thereby ensuring the production process and product quality.

[0039] Specifically, the second cleaning pad 21 in the above-mentioned split structure cleaning pad 2 of the present invention is used to clean the debris on the inner wall of the extrusion cylinder, and the first cleaning pad 20 is used to clean the debris on the inner wall of the extrusion cylinder with the second cleaning pad 21, and then lubricate the inner wall of the extrusion cylinder after blowing with the second cleaning rod 3 and the end cover 4.

[0040] Specifically, Figure 3-Figure 6 As shown, in the reverse copper extruder cleaning device with cleaning and lubricating functions of the present invention, a boss 202 is provided at one end of the first cleaning pad, and a first groove 203 is provided on the boss 202, so that the lubricating fluid pipeline 41 can be wound around the outer periphery of the boss 202 through the first groove 203, and a plurality of third through holes 204 are provided on the lubricating fluid pipeline 41 wound around the outer peripheral portion of the boss 202, and a plurality of second grooves 205 are provided at the other end of the first cleaning pad as channels for compressed air to blow away debris in the extrusion barrel.

[0041] In some optional implementations of this embodiment, the lubricating liquid pipeline 41 can be set to any one of a copper tube, an aluminum tube, a stainless steel tube or a hard plastic tube. In this way, the lubricating liquid pipeline 41 has a certain strength and is not easily corroded or rusted, and is easy to be wound around the boss 202 of the first cleaning pad 20.

[0042] In order to enable the lubricating liquid pipeline 41 to fit the boss 202 on the first cleaning pad 20, avoid the first cleaning pad 20 from being squeezed and deformed between the boss 202 and the first cleaning rod 1, and avoid the first cleaning pad 20 from loosening during the lubrication process and interfering with the inner wall of the extrusion cylinder, one end face of the first cleaning pad 20 is flush with the outer end face of the boss 202, the other end face of the first cleaning pad 20 is tightly fitted with the surface of the boss 202, and the outer periphery of the first cleaning pad 20 is set to be the same as the outer diameter of the first cleaning rod 1.

[0043] In order to ensure that the lubricating liquid pipeline 41 lubricates the inner wall of the extrusion cylinder evenly, a plurality of through holes for spraying the lubricating liquid are evenly arranged on the lubricating liquid pipeline 41 arranged on the boss 202. At the same time, in order to improve the lubrication efficiency, reduce the waste of lubricating liquid, and ensure the uniformity of lubrication inside the extrusion cylinder, a plurality of circles of staggered small through holes can be arranged along the lubricating liquid pipeline 41 arranged on the boss 202, so that the lubricating liquid forms a spray to lubricate the inner wall of the extrusion cylinder.

[0044] In the reverse copper extruder cleaning device with cleaning and lubricating functions of the present invention, the first cleaning pad and the second cleaning pad are connected by threads.

[0045] As an example, the first cleaning pad 20 and the second cleaning pad 21 are connected by bolts.

[0046] As another example, the first cleaning pad 20 and the second cleaning pad 21 are connected by screws.

[0047] Such arrangement, through the method of connection by screws or bolts, has a simple structure and occupies less space on the one hand, and is easy to disassemble and has low cost on the other hand.

[0048] Specifically, in the reverse copper extruder cleaning device with cleaning and lubrication functions of the present invention, a first inclined surface 206 is provided on the periphery of one end of the first cleaning pad contacting the second cleaning pad, and a second inclined surface 210 matching the first inclined surface 206 is provided on the periphery of one end of the second cleaning pad contacting the first cleaning pad, and the gap between the first inclined surface 206 and the second inclined surface 210 is matched to form a wind knife surface for compressed air to pass through.

[0049] Such arrangement enables the compressed air to have a strong pressure when it is blown out along the wind knife surface, forming a high-pressure airflow, thereby being able to thoroughly clean the fine impurities and firmly attached impurities that cannot be cleaned by the second cleaning pad 21 on the inner wall of the extrusion cylinder. At the same time, the wind knife surface formed by the first inclined surface 206 and the second inclined surface 210 can also play a role in draining and guiding the high-pressure airflow formed by the compressed air.

[0050] In order to avoid blowing impurities toward the lubricated inner wall of the extrusion barrel during the process of using compressed air to blow away fine impurities on the inner wall of the extrusion barrel, the first inclined surface 206 and the second inclined surface 210 and the wind knife surface formed by them are arranged to face the side of the end cover 4.

[0051] In the reverse copper extruder cleaning device with cleaning and lubricating functions of the present invention, the end cover 4 is fixedly connected to the first cleaning rod 1 through threads.

[0052] Exemplarily, the end cover 4 is connected to the first cleaning rod 1 by bolts or screws.

[0053] In order to ensure that the end cover 4 has a good sealing effect after being connected to the first cleaning rod 1 and to prevent the compressed air from leaking in the gap between the end cover 4 and the first cleaning rod 1, thereby reducing the pressure of the compressed air and weakening the cleaning ability of the inner wall of the extrusion cylinder, a sealing pad or a sealant may be provided at the position where the end cover 4 contacts the first cleaning rod 1.

[0054] In the reverse copper extruder cleaning device with cleaning and lubricating functions of the present invention, the first cleaning rod 1 is integrally formed.

[0055] In some optional implementations of this embodiment, the first cleaning rod 1 may be forged from metal.

[0056] Such arrangement enables the first cleaning rod 1 to have a certain strength during the lubrication and cleaning process, and can maintain the lubrication and cleaning effects under the erosion of lubricating oil and the pressure of compressed air, and has a long service life.

[0057] Specifically, in the reverse copper extruder cleaning device with cleaning and lubrication functions of the present invention, in order to facilitate the control of the flow rate of the lubricating liquid, the size and flow rate of the compressed air and the on-off of the two, solenoid valves 5 are provided on the lubricating liquid pipeline 41 and the compressed air pipeline 40, so that the amount of compressed air and lubricating liquid can be adjusted as needed to ensure the lubrication and cleaning effects.

[0058] Specifically, in the reverse copper extruder cleaning device with cleaning and lubricating functions of the present invention, the air compression channel includes a channel opened along the radial direction of the end cover 4, and the lubricating liquid channel includes a pipeline arranged along the radial direction of the end cover 4.

[0059] In this way, by opening a through hole on the end cover 4 for compressed air to enter, the problem of compressed air leakage caused by the loose connection between the external pipeline and the end cover 4 is avoided, and the weight of the end cover 4 side is reduced, which facilitates the movement of the first cleaning rod 1 along the direction of the extrusion cylinder; by setting a lubricating liquid pipeline, the lubricating liquid pipeline 41 can be fixedly connected with the second cleaning rod 3, which facilitates the lubricating liquid pipeline 41 to pass the lubricating liquid to the second cleaning rod 3, and can also facilitate the distinction from the air compression pipeline, so that the extrusion cylinder can be quickly cleaned.

[0060] In some optional implementations of this embodiment, the lubricating fluid pipeline 41 can be connected to the second cleaning rod 3 by threads, such as providing an external thread on the lubricating fluid pipeline 41, and providing an internal thread matching the external thread of the lubricating fluid pipeline 41 on the hollow pipeline of the second cleaning rod 3, and the two are connected by threads.

[0061] The principle of the reverse copper extruder cleaning device with cleaning and lubricating functions of the present invention includes:

[0062] When cleaning the extrusion barrel, when the first cleaning rod 1 drives the cleaning pad 2, the second cleaning rod 3 and the end cover 4 to approach the extrusion barrel, the extrusion device of the present invention is extended and retracted along the direction of the extrusion barrel to clean and lubricate the barrel wall. Specifically, the lubricating liquid pipeline 41 provided in the end cover 4 is connected with the external lubricating liquid in advance, and the compressed air pipeline 40 is connected with the external compressed air. The solenoid valves 5 provided on the lubricating liquid pipeline 41 and the compressed air pipeline are opened respectively, and the corresponding flow rates are adjusted. In the process of the first cleaning rod 1 driving the cleaning pad 2, the second cleaning rod 3 and the end cover 4 to enter the extrusion barrel, the second cleaning pad 21 is located at The coarser debris and impurities with less adhesion inside the extrusion barrel are cleaned, and during the return process after the second cleaning pad 21 cleans, the fine impurities and impurities with strong adhesion inside the extrusion barrel are cleaned through the lubricating liquid pipeline 41 and the air compression pipeline, and the inner wall of the extrusion barrel is lubricated, so that the inner wall of the extrusion barrel can be cleaned, purged and lubricated in one operation, so that the above three operations can be completed in one action without adding additional actions and affecting the working efficiency of the whole machine, realizing the replacement of manual labor, ensuring the quality of operation, and providing sufficient preparation for the next operation.

[0063] In some optional implementations of the present embodiment, in order to avoid the second cleaning rod 3 from tilting and bending inside the first through hole 10 of the first cleaning rod 1, and to avoid interference with the first through hole 10 of the first cleaning rod 1, thereby affecting the cleaning, lubrication and purging effects on the extrusion cylinder, one or more support members are provided on the second cleaning rod 3.

[0064] In the reverse copper extruder cleaning device with cleaning and lubrication functions of the present invention, in order to further improve the quality and efficiency of cleaning, purging and lubricating the extrusion barrel, further reduce manual participation, realize the above three operations on the extrusion barrel at a fixed time, and further realize automated operation, a lifting rod and a control unit driven by a motor can be set on the side of the end cover 4, so that the control unit can control the on and off of the solenoid valve 5 set on the lubricating fluid pipeline 41 and the compressed air pipeline 40 and automatically adjust the opening of the solenoid valve 5, so that the flow of the lubricating fluid and the compressed air can be adjusted to achieve different lubrication effects and purging effects. At the same time, the control unit can also control the lifting and lowering of the lifting rod, so that the lifting rod can drive the first cleaning rod 1 while driving the movement of the cleaning pad 2, the second cleaning rod 3 and the end cover 4.

[0065] In summary, the reverse copper extruder cleaning device with cleaning and lubrication functions of the present invention can clean, purge and lubricate the extrusion barrel in one action, can realize mechanized and automated cleaning and lubrication of the inner wall of the extrusion barrel, and ensure the production process and product quality.
