Description

Technical Field

[0001] This utility model relates to the field of rolling technology, specifically to a continuous rolling mechanism for processing copper strip. Background Technology

[0002] Copper strip is made of copper and has a strip-shaped structure. During the processing of copper strip, a rolling device is often used to roll the thick synchronous belt into a thinner copper strip so that the copper strip meets the requirements for use.

[0003] In continuous rolling of copper strip, friction between the rolling rollers and the copper strip generates metal debris, which accumulates between the rollers. This causes metal debris to easily adhere to the surface of the pressure rollers. The debris particles are pressed into the copper strip surface by the rolling rollers, causing indentations and scratches. Traditional processes use rigid scrapers to remove debris to ensure roller surface cleanliness. However, when the scraped debris mixes with coolant and flows through the guide plate, the oleophilic nature of copper powder and the surface tension of the coolant form a viscous slurry that adheres to the plate surface and easily accumulates on the guide plate, requiring frequent cleaning and further increasing labor. Therefore, this invention designs a continuous rolling mechanism for processing copper strip to solve the problems existing in the prior art. Utility Model Content

[0033] 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.

[0034] Please see Figure 1-13 The present invention provides an embodiment of a continuous rolling mechanism for processing copper strip, comprising: a base 1, and a rolling mechanism 2 disposed on the top of the base 1;

[0035] The rolling mechanism 2 includes: a pressure roller 201 and a motor 203. There are two pressure rollers 201, which are symmetrically rotated and mounted on the base 1. A first gear 202 meshes between one end of the two pressure rollers 201. The motor 203 is fixedly mounted on the base 1. The output end of the motor 203 is fixedly connected to a second gear 204 that meshes with the adjacent first gear 202. A cleaning mechanism 3 for cleaning debris is provided on one side of the pressure roller 201. Since the two pressure rollers 201 rotate in opposite directions, the cleaning mechanisms 3 on the upper and lower pressure rollers 201 are staggered to facilitate the cleaning of debris. A liquid storage tank 6 is fixedly mounted on the surface of the base 1, and Y-shaped connecting pipes 601 are symmetrically fixedly mounted on both ends of the liquid storage tank 6. The upper end of the Y-shaped connecting pipe 601 is connected to the interior of one end of the adjacent cleaning mechanism 3.

[0036] During the continuous rolling of copper strip, the output end of motor 203 drives the second gear 204 to mesh with the adjacent first gear 202. Then, the first gear 202, which meshes with one end of the two pressure rollers 201, rotates, causing the upper and lower pressure rollers 201 to rotate and roll the copper strip.

[0037] In an embodiment of this utility model: the cleaning mechanism 3 includes a scraper 301, which rests on the surface of the pressure roller 201. A collection box 302 is detachably mounted on the scraper 301. The scraper 301 and the collection box 302 are fixedly connected by bolts. Both sides of the collection box 302 are fixedly mounted on the base 1. A reciprocating screw 304 is rotatably mounted inside the collection box 302, and scrapers 303 are symmetrically and movably mounted on the surface of the reciprocating screw 304. It should be noted that the bottom of the scraper 303... The sides of the parts that are far apart are sloped, which facilitates the scraping of debris as the scraper 303 descends. Both ends of the collection box 302 are connected to the mounting box 305, and the inside of the mounting box 305 is fitted with a slag storage box 306. The top of the Y-shaped connecting pipe 601 is connected to the bottom of the mounting box 305 and the bottom of the collection box 302 respectively. A transmission component 4 is provided between one end of the reciprocating screw 304 and one end of the adjacent pressure roller 201. A pressing component 5 for pressing debris is provided on the top of the scraper 303.

[0038] In copper strip rolling, tiny metal debris is generated on the surface of the copper strip during rolling. After mixing with the coolant, the debris easily adheres to the surface of the pressure roller 201, which can easily cause surface defects such as indentations and scratches on the copper strip, affecting the quality of the copper strip. In the rolling process, the scraper 301 first scrapes the debris and excess coolant from the surface of the pressure roller 201 into the collection box 302. As the pressure roller 201 rotates, the reciprocating screw 304 drives the two scrapers 303 with symmetrical threads installed on its surface to move in opposite directions, scraping the metal debris scraped by the scraper 301 into the collection box 302 to both sides of the collection box 302, reducing the accumulation of debris in the collection box 302.

[0039] In an embodiment of this utility model: a trapezoidal guide groove 3021 is provided on the inner wall of the collection box 302, and limit blocks 3022 are fixedly installed on both sides of the upper end of the trapezoidal guide groove 3021, and one side of the scraper 303 slides in the adjacent trapezoidal guide groove 3021.

[0040] The trapezoidal guide groove 3021 is an inverted trapezoid. After the two scrapers 303 approach each other and are in position, the first spring 3033 elastically resets and pushes the scraper 303 downward, so that the bottom of the scraper 303 moves down to the bottom wall of the collection box 302. Then the two scrapers 303 contact the bottom wall of the collection box 302 at the bottom. As the scrapers 303 move, they scrape the debris inside the collection box 302 to both sides.

[0041] In this embodiment of the invention: a threaded sleeve 3031 is installed on the top of the scraper 303, and the middle part of the threaded sleeve 3031 is threadedly connected to the surface of the reciprocating screw 304. The top of the threaded sleeve 3031 is slidably installed on the top wall of the collection box 302. Threads are provided at both ends of the reciprocating screw 304, and the thread directions at the left and right ends are opposite. It should be noted that by providing threads at both ends, the two scrapers 303 can simultaneously move closer or further apart.

[0042] In an embodiment of this utility model: a movable rod 3032 is vertically inserted through the middle of the scraper 303, and the top of the movable rod 3032 is fixedly connected to the bottom of the threaded sleeve 3031. A first spring 3033 is fixedly connected between the bottom of the movable rod 3032 and the interior of the scraper 303. A guide pin 3034 is movably inserted through one side of the scraper 303, and one end of the guide pin 3034 is slidably installed in the adjacent trapezoidal guide groove 3021. A second spring 3035 is fixedly connected between the other end of the guide pin 3034 and the inner wall of the scraper 303.

[0043] After the reciprocating screw 304 drives the two symmetrical scrapers 303 to almost reach their positions, the guide pin 3034 on one side of the scraper 303 moves up along the inclined surface of the trapezoidal guide groove 3021. When the scraper 303 reaches its position, the limiting block 3022 restricts the guide pin 3034 from moving down, so that the guide pin 3034 can only move horizontally at the upper end of the trapezoidal guide groove 3021. After the guide pin 3034 drives the scraper 303 to move horizontally into position, the limiting block 3022 restricts the guide pin 3034 again. At this time, the scraper 303 descends under the elastic reset of the first spring 3033, causing the guide pin 3034 to move into the guide groove at the lower end of the trapezoidal guide groove 3021. This reciprocating motion causes the two scrapers 303 to rise when they are close together, without cleaning the debris, and to descend when they are far apart to clean the waste in the collection box 302, thus achieving automatic cleaning and reducing labor.

[0044] In an embodiment of this utility model: the top of the mounting box 305 has an opening, and the slag collection box 306 is inserted into the mounting box 305 through the opening at the top of the mounting box 305. The bottom of the slag collection box 306 has filter holes arranged at equal intervals. It should be noted that metal filter screens are provided at the connection points between the two ends of the collection box 302 and the Y-shaped connecting pipe 601. When metal debris is pushed to both sides of the collection box 302, the coolant flows through the filter screen into the liquid storage tank 6 at the lower end of the Y-shaped connecting pipe 601, and the coolant in the waste debris inside the slag collection box 306 flows through its bottom into the Y-shaped connecting pipe 601 under pressure.

[0045] In an embodiment of this utility model: the transmission assembly 4 includes a first pulley 401 and a second pulley 402. The first pulley 401 is fixedly installed at one end of the reciprocating screw 304, and the second pulley 402 is fixedly installed at one end of the pressure roller 201. A belt 403 is installed between the first pulley 401 and the second pulley 402. During the rotation of the pressure roller 201, the pressure roller 201 drives the belt 403 via the second pulley 402, causing the belt 403 to drive the first pulley 401 at the end of the reciprocating screw 304 to rotate, thus realizing the rotation of the reciprocating screw 304.

[0046] In an embodiment of this utility model: the extrusion assembly 5 includes: a guide rod 501, a third spring 503, a push rod 506, and a hook 507. The guide rod 501 is fixedly installed at one end inside the collection box 302. A pressure plate 502 is slidably installed on the surface of the guide rod 501, and the pressure plate 502 is elastically connected to the collection box 302 through the third spring 503. A hinge rod 504 is hingedly installed on the top of the pressure plate 502, and a U-shaped block 505 is hingedly installed at one end of the hinge rod 504. One side of the U-shaped block 505 is slidably installed on the inner wall of the collection box 302. The lower end of the hook 507 is rotatably connected to the top of the scraper 303 through a torsion spring. The end of the hook 507 near the U-shaped block 505 is inclined, which facilitates the deflection of the hook 507 when it is extruded by the U-shaped block 505. The push rod 506 is fixedly installed on the inner wall of the collection box 302, and the push rod 506 cooperates with the hook 507.

[0047] When the scraper 303 approaches one end of the collection box 302, the hook 507, which is rotatably mounted on the top of the scraper 303 via a torsion spring, presses against the surface of the upper end of the U-shaped block 505. At this time, the hook 507 flips upward after being pressed by the inclined plane. When the pressure is released, the torsion spring drives the hook 507 to flip back to its original position, so that it is locked onto the upper end of the U-shaped block 505. When the two scrapers 303 approach each other, the hook 507 pulls the U-shaped block 505 to move. At this time, the hinge rod 504 hinged on the U-shaped block 505 drives the pressure plate 502 to slide on the guide rod 501, thereby scraping the scraper 303. The waste debris at both ends of the collection box 302 is squeezed into the slag box 306 inside the mounting box 305. Through the squeezing of the waste debris, some of the coolant in the waste debris can be squeezed out, improving the separation efficiency of coolant and waste debris. When the scraper 303 drives the U-shaped block 505 to the push rod 506, the lower end of the hook 507 is restricted by the push rod 506, causing the hook 507 to flip upward again. The hook 507 releases the lock on the U-shaped block 505. At the same time, the third spring 503 elastically resets, pushing the pressure plate 502 to the initial position, which is convenient for the next waste debris squeezing.

[0048] Working principle: In the copper strip rolling process, the reciprocating screw 304 is rotated by the transmission assembly 4. First, the reciprocating screw 304 drives two scrapers 303 with symmetrical threads mounted on its surface to move in opposite directions, cleaning the waste from the collection box 302 to both ends. After the reciprocating screw 304 drives the two symmetrical scrapers 303 to almost reach their final positions, the guide pin 3034 on one side of the scraper 303 moves up through the inclined surface of the trapezoidal guide groove 3021. When the scraper 303 rises to its final position, the limit block 302... 2. The guide pin 3034 is restricted from moving downward, so that the guide pin 3034 can only move horizontally at the upper end of the trapezoidal guide groove 3021. After the guide pin 3034 drives the scraper 303 to move horizontally into place, the limiting block 3022 restricts the guide pin 3034 again. At this time, the scraper 303 descends under the elastic reset of the first spring 3033, so that the guide pin 3034 moves into the guide groove at the lower end of the trapezoidal guide groove 3021. This process is repeated so that the two scrapers 303 will not clean metal debris while rising.

[0049] Furthermore, when the scraper 303 approaches one end of the collection box 302, the hook 507, which is rotatably mounted on the top of the scraper 303 via a torsion spring, presses against the surface of the upper end of the U-shaped block 505. At this time, the hook 507 flips upward after being pressed by the inclined surface. When the pressure is released, the torsion spring drives the hook 507 to flip back to its original position, so that it is locked onto the upper end of the U-shaped block 505. When the two scrapers 303 approach each other, the hook 507 pulls the U-shaped block 505 to move. At this time, the hinge rod 504 hinged on the U-shaped block 505 drives the pressure plate 502 to slide on the guide rod 501, thereby squeezing the waste scraped by the scraper 303 to both ends of the collection box 302 into the slag box 306 inside the mounting box 305. Through the squeezing of the waste, some of the coolant in the waste can be squeezed out. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0050] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
