Description

Technical Field

[0001] This invention relates to the field of copper strip production technology, specifically a continuous rolling mill for copper strip. Background Technology

[0002] White copper strip is a copper alloy strip with copper as the base and mainly containing alloying elements such as tin and zinc. It is an important copper processing material in the industrial field that combines functionality and economy. During the processing of white copper strip, it needs to be rolled into shape by a rolling mill. In order to reduce mechanical wear on the surface of the rolls, avoid roll scratches and indentations caused by friction, ensure roll accuracy, and avoid local deformation of the rolls due to overheating caused by friction, and maintain the stability of continuous rolling, rolling fluid needs to be sprayed onto the surface of the rolls during the rolling process. Since the rolling fluid is usually sprayed during processing, this method will cause a large amount of rolling fluid to be sprayed into the non-contact area of ​​the roll, such as the ends of the roll body. At this time, some rolling fluid will be lost without participating in softening and cooling. Furthermore, when the roll rotates at high speed, the excess rolling fluid sprayed on its surface will splash due to centrifugal force and cannot be retained in the action area, thus wasting rolling fluid resources. Therefore, we propose a continuous rolling mill for white copper strip to solve the above problems. Summary of the Invention

[0020] (III) Beneficial Effects

[0021] Compared with the prior art, the present invention provides a continuous rolling mill for copper strip, which has the following advantages:

[0022] This invention, by installing a coating device on the support of the rolling roll, employs a method of spraying the rolling slurry onto a coating roll, which then uniformly coats the surface of the rolling roll. This method not only ensures that the rolling slurry forms a uniform and continuous oil film layer on the surface of the rolling roll, but also avoids a large amount of rolling slurry being sprayed into the non-contact areas of the rolling roll due to the non-direct spraying method. Furthermore, it further avoids the situation where excess rolling slurry on the surface of the rolling roll causes swirling splashing, reducing the waste of rolling slurry resources. The cleaning mechanism in the coating device can scrape off and collect residual impurities and used rolling slurry from the surface of the rolling roll, preventing the surface of the rolling roll from being affected by impurities in the subsequent rolling of copper strip. At the same time, it can also collect and process a portion of the used rolling slurry for subsequent recycling.

[0023] This invention, by installing a cleaning mechanism on the support frame, allows the cleaning brush in the cleaning mechanism to remove dust and other impurities adhering to the surface of the copper strip before rolling, thus preventing the presence of impurities from affecting the quality of subsequent rolling. Furthermore, the dust and other impurities can be collected in real time using a dust collection hood while cleaning, thereby preventing the cleaned impurities from adhering to the surface of the copper strip again.

[0037] 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.

[0038] Example

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 12As shown in one embodiment of the present invention, a continuous rolling mill for copper strip includes a support frame 1. Two auxiliary rollers 7 are fixed between the inner walls of both sides of the support frame 1. By providing auxiliary rollers 7 at both ends of the support frame 1, they can provide auxiliary support for the copper strip during the rolling process. Two hydraulic cylinders 2 are fixed on the support frame 1. The ejector ends of the hydraulic cylinders 2 slide through the support frame 1 and extend into its interior, where they are fixed with support seats 3. Four T-shaped guide rods slide through the support frame 1, one end of which is respectively connected to a corresponding... The support base 3 is fixed, and when the support base 3 moves, it can play an auxiliary support and guidance role. The inner walls on both sides of the support base 3 are rotatably connected to the rolling rolls 4 through bearings. The two rolling rolls 4 are driven by a drive motor coupling. Since it is existing technology, the driving method of the two rolling rolls 4 is not shown in the figure. The support base 3 is equipped with a coating device 5 for wiping the surface of the rolling rolls 4 with rolling liquid. The two coating devices 5 have the same composition and structure, and their installation position is fixed according to the rotation direction of the rolling rolls 4.

[0040] The coating device 5 includes a bracket 51 fixed on a support base 3. A coating roller 52 is rotatably connected between the inner walls of the two sides of the bracket 51 via bearings. A servo motor is fixed on one side wall of the bracket 51, and the drive shaft of the servo motor is fixed to one end of the coating roller 52, thus enabling the coating roller 52 to rotate. The coating roller 52 is made of hydrophilic rubber, which can adsorb the rolling liquid to a certain extent. Therefore, when the coating roller 52 is in contact with the surface of the rolling roller 4 and a certain amount of pressure is generated, the rolling liquid can be evenly coated on the surface of the rolling roller 4. The coating roller 52 is in contact with the surface of the rolling roller 4. A liquid extraction cylinder 53 is fixed on the bracket 51. A one-way liquid outlet valve is installed on the one-way liquid inlet pipe of the liquid extraction cylinder 53, and a one-way liquid inlet valve is installed on the one-way liquid inlet pipe of the liquid extraction cylinder 53, thus enabling the coating roller 52 to be evenly coated with the rolling liquid. The rolling liquid is drawn into its interior, and for ease of use, an electric control valve can be installed on its one-way outlet pipe to control the amount of liquid discharged from the spray plate 54. The spray plate 54 is set above the coating roller 52, and the number of nozzles on the spray plate 54 can be opened according to the width of the copper strip. One end of the one-way outlet pipe of the suction cylinder 53 is connected and fixed to the spray plate 54. The suction piston 55 is slidably connected inside the suction cylinder 53. One end of the suction piston 55 slides through the suction cylinder 53 and extends to its exterior. A support plate 56 is fixed to one side wall of the bracket 51. The side wall of the support plate 56 is rotatably connected to the rotating shaft 57 through the bearing. A reciprocating mechanism 58 for driving the suction piston 55 to move back and forth is installed on the rotating shaft 57. A cleaning mechanism 59 for cleaning the surface of the rolling roller 4 is installed on the bracket 51.

[0041] The reciprocating mechanism 58 includes a rotating plate 581 fixed to one end of a rotating shaft 57. A reciprocating rod 582 is rotatably connected to one side wall of the rotating plate 581 via a pin. A moving rod 583 is fixed to one end of the reciprocating rod 582. A moving frame 584 is fixed to one end of the moving rod 583. One end of the liquid-drawing piston 55 is fixedly connected to one side wall of the moving frame 584. A drive shaft 585 is rotatably connected between the inner walls of the two sides of the support 51 via a bearing. A bevel gear 586 is fixed to the surface of the drive shaft 585. A bevel gear 587 is fixed to the surface of the rotating shaft 57. The bevel gear 587 meshes with the bevel gear 586. A guide block 588 for limiting the reciprocating rod 582 is fixed to one side wall of the support plate 56.

[0042] Working principle and usage process of this invention: During the continuous rolling mill of copper strip, one end of the copper strip to be processed is passed from left to right between two rolling rolls 4. The rotation of the rolling rolls 4 is driven by the drive motor and the coupling. The distance between the two upper and lower rolling rolls 4 can be adjusted by the two hydraulic cylinders 2. During the adjustment of the distance between the upper and lower rolling rolls 4, the height of the drive motor and the coupling does not need to be adjusted synchronously. The core reason is that the structural design of the transmission system and the roller system adjustment mechanism are independent of each other. The roller distance can be changed but the power transmission path is constant through a specific mechanical structure. Since this is existing technology, it will not be described in detail here.

[0043] When the rolling roll 4 needs to be coated with rolling fluid during operation, firstly, the one-way inlet pipe on the suction piston cylinder 55 is extended and placed inside the rolling fluid storage tank and fixed. When the starting motor drives the coating roll 52 to rotate, it will drive the drive shaft 585 to rotate. After the drive shaft 585 rotates, it will drive the bevel gear 586 to rotate. After the bevel gear 586 rotates, it will drive the rotating shaft 57 to rotate through the engagement of the bevel gear 587. After the rotating shaft 57 rotates, it will drive the rotating plate 581 to rotate. When the rotating plate... After rotation, 581, in cooperation with guide block 588, drives reciprocating rod 582 to move back and forth. The reciprocating rod 582's back-and-forth movement drives moving rod 583 to move back and forth, which in turn drives moving frame 584 to move back and forth. Because one end of the suction piston 55 is fixedly connected to one side wall of moving frame 584, the suction piston 55 can move back and forth inside suction cylinder 53. When the suction piston 55 moves, it draws fluid from inside suction cylinder 53. After the air is expelled, the rolling fluid can be drawn into the pump cylinder 53 and then sent to the spray plate 54 for spraying. The rolling fluid sprayed by the spray plate 54 will adhere to the surface of the coating roller 52. When the coating roller 52 rotates, the rolling fluid can be evenly coated on the surface of the rotating rolling roller 4. After the rolling roller 4 is coated with rolling fluid, it will continue to rotate and come into contact with the surface of the copper strip to be processed, thus facilitating its rolling and forming. After the rolling fluid on the surface of the rolling roller 4 is used, when it continues to rotate, the cleaning mechanism 59 can scrape off and collect any impurities and rolling fluid that may have remained on its surface due to rolling. After the rolling fluid and impurities are scraped off, the rolling roller 4 can continue to rotate to the coating roller 52, and then the coating roller 52 will continue to coat its surface with rolling fluid. This cycle is repeated, which avoids the rolling fluid being sprayed into the non-contact area of ​​the rolling roller 4 by the spray method, thus avoiding the waste of rolling fluid resources.

[0044] like Figure 3 , Figure 7 and Figure 9As shown, in some embodiments, the cleaning mechanism 59 includes a collection cylinder 591 fixed to the suction cylinder 53. When the discharge pipe of the collection cylinder 591 shown in the figure is two detachable sections, it prevents subsequent minor blockages in the discharge pipe from hindering unblocking. A spray plate 54 is fixed to the outer wall of the collection cylinder 591. A rotating rod 592 is rotatably connected to the inside of the collection cylinder 591 via bearings. A spiral blade 593 is fixed to the surface of the rotating rod 592. A spiral rubber strip, matching the shape of the spiral blade 593, is fixed to the surface of the spiral blade 593. The spiral rubber strip fits tightly against the inner wall of the collection cylinder 591, thereby enhancing the effect of the spiral blade 593 in pushing the impurity rolling liquid mixture when rotating. The two sections of the collection cylinder 591... A scraper 594 adapted to the rolling roll 4 is provided between the inner walls of the side. T-shaped sliders 597 are slidably connected to the inner walls of both sides of the collecting cylinder 591. The scraper 594 is fixed between the two T-shaped sliders 597. Two springs 598 are fixed on each T-shaped slider 597. The other end of each spring 598 is fixedly connected to the collecting cylinder 591. In use, a rubber scraper strip is fixed to one side wall of the scraper 594. The rubber scraper strip is in contact with the surface of the rolling roll 4, thereby enhancing the impurity removal effect of the scraper 594 and preventing damage to the surface of the rolling roll 4 caused by direct contact between the scraper 594 and the surface of the rolling roll 4. When the scraper 594 is in contact with the surface of the rolling roll 4, the springs 598 are compressed. In this state, when the rubber scraper blade experiences some wear, the reset force of the compressed spring 598 ensures that the rubber scraper blade remains in close contact with the surface of the rolling roll 4, preventing any impact on its cleaning performance. One side wall of the scraper blade 594 is in close contact with the surface of the rolling roll 4. A reciprocating screw 595 is rotatably connected between the two inner walls of the bracket 51 via bearings. A cleaning plate 596, adapted to the scraper blade 594, is fixed to the surface of the reciprocating screw 595. During use, because one side wall of the scraper blade 594 is in contact with the surface of the rolling roll 4, when the rolling roll 4 rotates, any impurities that may be present on its surface, as well as the used rolling fluid, can be scraped onto the scraper blade 594. When the coating roller 52 rotates, it drives the rotating rod 592 and the reciprocating screw 595 to rotate. When the reciprocating screw 595 rotates, it drives the cleaning plate 596 to move back and forth on the surface of the scraper 594, thereby scraping some of the rolling liquid impurity mixture that has not fallen off the scraper 594 into the inside of the collection cylinder 591. When the rotating rod 592 rotates, it drives the spiral blade 593 to rotate. At this time, under the action of the spiral blade 593, the impurity rolling liquid mixture can be continuously pushed to the discharge pipe at one end of the collection cylinder 591 for discharge. Afterwards, one end of the discharge pipe is extended and connected and fixed to the waste liquid collection box to collect the waste liquid for subsequent treatment and recycling.

[0045] like Figure 3As shown, in some embodiments, a drive mechanism 510 is mounted on the bracket 51 for driving the coating roller 52, the rotating shaft 57, the rotating rod 592 and the reciprocating screw 595 to rotate synchronously.

[0046] The drive mechanism 510 includes two drive shafts 5101 rotatably connected to the bracket 51 via bearings. A sprocket 5102 is fixed to the surfaces of the coating roller 52, drive shaft 585, rotating rod 592, and reciprocating screw 595. A sprocket 5103 is fixed to the surfaces of the two drive shafts 5101. The four sprockets 5102 and the two sprockets 5103 are connected by a chain 5104. In use, starting the servo motor drives the coating roller 52 to rotate. Then, with the cooperation of the four sprockets 5102, the two sprockets 5103, and the chain 5104, the coating roller 52, drive shaft 585, rotating rod 592, and reciprocating screw 595 can be driven to rotate synchronously, thus saving production costs.

[0047] like Figure 1 , Figure 2 , Figure 10 and Figure 11 As shown, in some embodiments, the support frame 1 is equipped with a cleaning mechanism 6 for cleaning the surface of the copper strip before rolling;

[0048] The cleaning mechanism 6 includes two guide rails 61 fixed on the support frame 1. A dust collection hood 62 is slidably connected between the two guide rails 61. Each of the six slots on the dust collection hood 62 contains a cleaning brush 620. The cleaning brushes 620 are soft-bristled and will not damage the surface of the copper strip to be processed. An air extraction cylinder 614 is fixed to the top of the two guide rails 61. An inlet one-way valve is installed on the inlet one-way pipe of the air extraction cylinder 614, and an outlet one-way valve is installed on its outlet one-way pipe, thus enabling dust extraction. The interior of the air extraction cylinder 614... A suction piston 615 is slidably connected to the suction cylinder 614. One end of the suction piston 615 slides through the suction cylinder 614, extends to its exterior, and is fixedly attached to a movable plate 616. The movable plate 616 is fixedly connected to the dust collection hood 62. A filter box 617 is fixedly attached to the top of the suction cylinder 614. A filter screen 618 is fixedly attached inside the filter box 617. Flexible hoses 619 are fixedly connected to both sides of the filter box 617. The other ends of the flexible hoses 619 are fixedly connected to the top of the dust collection hood 62. The top end of the one-way air inlet pipe of the suction cylinder 614 is connected to the bottom of the filter box 617. When the top cover of the filter box 617 is removable, it facilitates cleaning when there are many impurities filtered on the surface of the subsequent filter screen 618. During use, as the conveying copper belt moves inside the dust collection hood 62, multiple cleaning brushes 620 inside clean the impurities adhering to its surface. Simultaneously, the back-and-forth movement of the dust collection hood 62 drives the suction piston 615, which in turn draws air from the suction cylinder 614. The air is discharged, creating a negative pressure inside the vacuum hood 62. This generates suction at the air inlet, allowing the dust that falls during the cleaning of the copper strip to be drawn into the filter box 617 through the two suction hoses 619. The filter screen 618 inside the filter box 617 intercepts the impurities, and the filtered air enters the exhaust cylinder 614 and is then discharged. This process collects the impurities that fall during the cleaning of the copper strip, preventing them from adhering to the surface of the copper strip again.

[0049] like Figure 4As shown, in some embodiments, a connecting block 63 is fixed to one side wall of the dust hood 62. A connecting rod 64 is rotatably connected to the connecting block 63 via a pin. The other end of the connecting rod 64 is rotatably connected to a fixing block 65 via a pin. The fixing block 65 is fixedly connected to the reciprocating rod 582. In use, since the fixing block 65 is fixedly connected to the reciprocating rod 582, when the reciprocating rod 582 moves longitudinally, the connecting block 63 can be driven to move laterally through the cooperation of the connecting rod 64. After the connecting block 63 moves laterally, the dust hood 62 and the cleaning brush 620 can be driven to move back and forth, so as to enhance the cleaning effect of the cleaning brush 620 on the surface of the copper strip. Furthermore, through the cooperation of the connecting block 63, the connecting rod 64, and the fixing block 65, no additional power source is required when the dust hood 62 and the cleaning brush 620 move back and forth.

[0050] like Figure 3 , Figure 8 and Figure 10 As shown, in some embodiments, a connecting rod 66 is rotatably connected to the connecting block 63 via a pin, and a fixing block 67 is rotatably connected to the other end of the connecting rod 66 via a pin. A connecting shaft 68 is rotatably connected to the side wall of the support plate 56 via a bearing. A circular plate 69 is fixed to one end of the connecting shaft 68, and a drive rod 610 is movably connected to one side wall of the circular plate 69 via a pin. The fixing block 67 is fixedly connected to the drive rod 610. A bevel gear 611 is fixed to the surface of the transmission shaft 585, and a bevel gear 612 is fixed to the surface of the connecting shaft 68. The bevel gear 611 and the bevel gear 612 are meshed together. A guide block 613 for limiting the drive rod 610 is fixed to one side wall of the support plate 56. Although the reciprocating movement of the dust hood 62 and the cleaning brush 620 is achieved by the reciprocating rod 582, the reciprocating movement of the dust hood 62 and the cleaning brush 620 is driven by the reciprocating rod 582. Since the movement of both is driven by one side, it may lead to uneven reciprocating sliding. In this case, through the cooperation of components such as the drive rod 610, the circular plate 69, and the connecting shaft 68, when the drive shaft 585 rotates, it will drive the bevel gear 611 to rotate. After the bevel gear 611 rotates, it will drive the connecting shaft 68 to rotate with the cooperation of the bevel gear 612. After the connecting shaft 68 rotates, it will drive the circular plate 69 to rotate. When the circular plate 69 rotates, it will drive the drive rod 610, which is movably connected on one side, to move back and forth with the cooperation of the guide block 613. After the drive rod 610 moves back and forth, the connecting rod 66 and the fixing block 67 can work together with the connecting rod 64 and the fixing block 65, so that the dust cover 62 and the cleaning brush 620 can slide back and forth more smoothly.

[0051] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. 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.
