Description

Technical Field

[0001] The present invention relates to the technical field of strip rolling, and particularly relates to a strip composite device and a strip composite rolling system. Background Art

[0002] With the rapid development of high-end manufacturing, the precision and compounding of manufacturing have been accelerated. The performance of single materials is increasingly difficult to meet the design and use requirements, promoting the development of metal materials towards precision, miniaturization, and multi-functionality. Precision composite strips improve the overall performance by compounding different materials. Due to their excellent electrical conductivity, thermal conductivity, and mechanical properties, they are widely used in industries such as electronics, communication, automotive, and aerospace. During the production of precision composite thin strips, there are significant differences in the mechanical properties of the materials, and there are problems with poor deformation coordination ability during cold rolling, resulting in the stacking of strip plates of different materials, and even the occurrence of insufficient bonding strength and cracking of the bonding interface. Moreover, the composite thin strip is prone to deviation during rolling, and the lateral deviation of the bimetallic thin strip will inevitably continue to accumulate during continuous rolling, leading to the problem of shear cutting and strip breakage. Currently, multi-roll mills are the main equipment for rolling composite thin strips, and their structure and procedures are complex. Therefore, in order to avoid the above problems during the rolling of composite thin strips by multi-roll mills, a low-roll mill is often used for pre-composite rolling before rolling the composite thin strip by a multi-roll mill. However, using a low-roll mill for pre-rolling and compounding increases the complexity of the strip composite process and affects the production efficiency. Summary of the Invention

[0004] To achieve the above purpose, the present invention provides the following technical solutions:

[0005] In the first aspect, the present invention provides a strip composite device, including:

[0006] A box body;

The electric control box is electrically connected to the upper conductive roller and the lower conductive roller through the electric brushes. The electric brushes are arranged in an axial array along the upper conductive roller and the lower conductive roller and are in sliding contact with the surfaces of the upper conductive roller and the lower conductive roller.

[0012] Optionally, in the above strip compounding device, the strip compounding device further includes a cooling roller system. The cooling roller system is located at the outlet end of the current compounding roller system. The cooling roller system includes an upper cooling roller group, a lower cooling roller group, a first driving mechanism and a cooling box. Among them, the upper cooling roller group and the lower cooling roller group are arranged oppositely on the box body. The upper cooling roller group includes a plurality of upper cooling rollers arranged in parallel. The lower cooling roller group includes a plurality of lower cooling rollers arranged in parallel. Both the upper cooling rollers and the lower cooling rollers contain a first cooling medium. The upper cooling rollers and the lower cooling rollers are used to contact the strip to be compounded for cooling. The first driving mechanism is arranged on the box body. The driving end of the first driving mechanism is connected to the upper cooling rollers and the lower cooling rollers and is used to drive the upper cooling rollers and the lower cooling rollers to rotate. The cooling box is fixedly arranged on the box body. The cooling box contains a second cooling medium. Through holes are formed on the box body, and the through holes are used for the second cooling medium to enter the box body.

[0013] Optionally, in the above strip compounding device, the cooling roller system further includes a cooling box. The cooling box is fixedly arranged on the box body. The cooling box contains a second cooling medium. Through holes are formed on the box body, and the through holes are used for the second cooling medium to enter the box body.

[0014] Optionally, in the above strip composite device, the strip composite device further includes an oil removal roll system, which is arranged on the side of the cooling roll system away from the current composite roll system. The oil removal roll system includes an upper oil removal roll group, a lower oil removal roll group and a second driving mechanism. Among them, the upper oil removal roll group and the lower oil removal roll group are arranged opposite to each other on the box body. The upper oil removal roll group includes a plurality of upper oil removal rolls arranged in parallel; the lower oil removal roll group includes a plurality of lower oil removal rolls arranged in parallel. The second driving mechanism is arranged on the box body, and the driving end of the second driving mechanism is connected to the upper oil removal roll and the lower oil removal roll for driving the upper oil removal roll and the lower oil removal roll to rotate. The oil removal roll system is used to prevent the oil in the twenty-high rolling mill from entering the strip composite device.

[0015] Optionally, in the above strip composite device, an oil absorption sleeve is sleeved on the surface of the oil removal roll. The oil removal roll is of a hollow structure, and oil holes are provided on the surface of the oil removal roll.

[0016] Optionally, in the above strip composite device, the strip composite device further includes a guiding component, which is arranged at the inlet end of the strip composite device.

[0017] Compared with the prior art, for the strip composite device provided by the present invention, when the strip to be composite enters the box body and reaches the corresponding position in the current composite roll system, the pressing assembly arranged on the box body is started. The pressing assembly applies a pressure to the current composite roll system to approach the strip to be composite, so that the upper conductive roll of the upper roll group and the lower conductive roll of the lower roll group are in close contact with the strip to be composite at the same time. Multiple parallel and alternately arranged upper conductive rolls and upper insulating rolls operate simultaneously. The upper conductive rolls conduct current, and the upper insulating rolls support the strip to be composite; similarly, multiple parallel and alternately arranged lower conductive rolls and lower insulating rolls operate simultaneously. The lower conductive rolls transmit current, and the lower insulating rolls support the transmission of the strip. At this time, the power supply assembly generates current. The power supply assembly is electrically connected to the upper conductive rolls and the lower conductive rolls, and the current flows into the contacted strip to be composite through these conductive rolls. Due to the staggered layout of the upper conductive rolls and the lower conductive rolls, the current forms a current loop on the mutually contacted strip to be composite along a partial length range of the strip to be composite. Under the action of the current, the temperature of the strip to be composite rises, its deformation resistance decreases accordingly, and it becomes easy to shape. At the same time, the diffusion rate of the internal atoms between at least two strips to be composite is accelerated. When the strip to be composite passes through the conductive roll group, atomic-level fusion is achieved through contact, and finally the strips are composite together to realize the pre-composite of different strips. In this way, compared with the original pre-composite using a rolling mill with a low number of rolls, which only relies on mechanical pressure to composite the strips, under the action of mechanical pressure, the strips need to be rolled through multiple passes, with complex operations and a long process. The strip composite device of the present invention enables the strip to complete pre-composite through the effect generated by the current on the strip, without the need for high-pressure and long-time rolling. While realizing the pre-composite of the strip, the pre-composite process is optimized and the production efficiency is improved.

[0022] Optionally, in the above strip composite rolling system, the strip composite rolling system further includes a tension adjusting device. The tension adjusting device is arranged between the uncoiler and the strip composite device, and the tension adjusting device includes:

[0023] A bracket;

[0026] Optionally, in the above strip composite rolling system, the floating tension roller includes a first tension roller, a second tension roller and a third tension roller, and the third driving mechanism includes a lead screw motor, a driving motor and a lead screw slider mechanism;

[0027] The first tension roller and the second tension roller are relatively fixedly arranged on the bracket, the driving motor is fixedly arranged on the bracket, and the driving end of the driving motor is connected to the first tension roller and the second tension roller for driving the first tension roller and the second tension roller to rotate;

[0029] Compared with the prior art, the beneficial effects achieved by the strip composite rolling system provided by the present invention are the same as those of the solution provided in the first aspect, and will not be elaborated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Please refer to Figures 1 - 5 As shown in the figure, the strip composite device 1 provided by the embodiment of the present invention includes: a box body 110, a current composite roll system 120, a power supply component 130, and a pressing component 140. Among them, the current composite roll system 120 is arranged on the box body 110, and the current composite roll system 120 includes an upper roll group 121 and a lower roll group 122 arranged oppositely; among them, the upper roll group 121 includes a plurality of upper conductive rolls 1211 and upper insulating rolls 1212 arranged in parallel and alternately; the lower roll group 122 includes a plurality of lower conductive rolls 1221 and lower insulating rolls 1222 arranged in parallel and alternately, and the upper conductive rolls 1211 and the lower conductive rolls 1221 are arranged staggeredly in the advancing direction of the strip 5 to be composite; the power supply component 130 is arranged in the box body 110, and the power supply component 130 is electrically connected to the upper conductive rolls 1211 and the lower conductive rolls 1221. The power supply component 130 forms an electrical conduction loop with the upper conductive rolls 1211, the lower conductive rolls 1221, and the strip 5 to be composite pressed between the upper roll group 121 and the lower roll group 122, and performs current composite on the strip 5 to be composite; the pressing component 140 is arranged on the box body 110 and is used to apply a pressure to the current composite roll system 120 to approach the strip 5 to be composite.

[0051] During specific implementation: Please refer to Figures 1 - 5, for the strip composite device 1 provided by the present invention, when the strip 5 to be composite enters the box body 110 and reaches the corresponding position in the current composite roll system 120, the pressing component 140 provided on the box body 110 is started. The pressing component 140 applies a pressure to the current composite roll system 120 close to the strip 5 to be composite, so that the upper conductive roll 1211 of the upper roll group 121 and the lower conductive roll 1221 of the lower roll group 122 are in close contact with the strip 5 to be composite at the same time. Multiple parallel and alternately arranged upper conductive rolls 1211 and upper insulating rolls 1212 operate simultaneously. The upper conductive rolls 1211 conduct current, and the upper insulating rolls 1212 support the strip 5 to be composite; similarly, multiple parallel and alternately arranged lower conductive rolls 1221 and lower insulating rolls 1222 operate simultaneously. The lower conductive rolls 1221 transmit current, and the lower insulating rolls 1222 support the transmission of the strip 5 to be composite. At this time, the power supply component 130 generates current. The power supply component 130 is electrically connected to the upper conductive roll 1211 and the lower conductive roll 1221, and the current flows into the contacted strip 5 to be composite through these conductive rolls. Due to the staggered layout of the upper conductive roll 1211 and the lower conductive roll 1221, a current loop is formed along a partial length range of the strip 5 to be composite on the mutually contacted strip 5 to be composite. Under the action of the current, the temperature of the strip 5 to be composite rises, its deformation resistance decreases accordingly, it becomes easy to be shaped, and at the same time, the diffusion rate of atoms inside the strip 5 to be composite accelerates. When the strip 5 to be composite passes through the conductive roll group, atomic-level fusion is achieved through contact, and finally they are composite together to realize the pre-composite of the strip 5 to be composite. In this way, compared with the original pre-composite realized by using a rolling mill with a low number of rolls, only relying on mechanical pressure to composite the strip 5 to be composite, under the action of mechanical pressure, the strip 5 to be composite needs to be rolled through multiple passes, the operation is complex and the process is long. The strip composite device of the present invention enables the strip 5 to be composite to complete pre-composite through the effect generated by the current on the strip 5 to be composite, without high-pressure and long-time rolling. While realizing the pre-composite of the strip 5 to be composite, the pre-composite process is optimized and the production efficiency is improved.

[0052] As a possible implementation, as Figure 5 shown, the power supply component 130 includes a first electrode and a second electrode. The first electrode is electrically connected to the upper conductive roll 1211, the second electrode is electrically connected to the lower conductive roll 1221, and the first electrode and the second electrode have opposite polarities.

[0053] Specifically, as Figure 5 shown, the power supply component 130 includes a positive electrode and a negative electrode respectively arranged on different sides of the strip 5 to be composite. The positive and negative electrodes of the power supply are respectively connected to different conductive rolls through wires. And the conductive loop is a loop from the positive electrode of the power supply component 130 through the conductive roll and a section along the length range of the strip 5 to be composite on the strip 5 to be composite to the negative electrode of the power supply component 130.

[0054] During specific implementation, the current flows out from the positive electrode of the power supply component 130, flows into the upper conductive roller 1211 connected to the positive electrode through a wire, enters the upper strip to be laminated 5 through the contact point between the conductive roller and the strip to be laminated 5, conducts in the upper strip to be laminated 5, then enters the lower strip to be laminated 5 through the contact surface of different strips to be laminated 5, then flows from the lower strip to be laminated 5 into the lower conductive roller 1221 connected to the negative electrode of the power supply component 130, and finally returns to the negative electrode of the power supply component 130 through a wire, forming a complete conductive loop. Such staggered arrangement of the upper conductive roller 1211 and the lower conductive roller 1221 enables different positions of the strip to be laminated 5 to be in full contact with the conductive roller during the operation of the strip to be laminated 5, ensuring the uniformity and stability of current conduction, enabling the strip to be laminated 5 to uniformly receive the action of current in the entire length direction, and ensuring the quality and efficiency of lamination of the strip to be laminated 5 under the action of electroplasticity.

[0055] It should be noted that the positive and negative electrodes of the power supply component 130 can be arbitrarily connected to the upper conductive roller 1211 or the lower conductive roller 1221 respectively, including the case where the positive electrode of the power supply component 130 is electrically connected to the upper conductive roller 1211 while the negative electrode is electrically connected to the lower conductive roller 1221; and the case where the positive electrode of the power supply component 130 is electrically connected to the lower conductive roller 1221 while the negative electrode is electrically connected to the upper conductive roller 1211.

[0056] In another embodiment, as Figure 6 shown, there are two power supply components 130, which are respectively distributed on different sides of the strip to be laminated 5. Each power supply component 130 has its own positive and negative electrodes and is respectively connected to different conductive rollers through wires.

[0057] During specific implementation, for the upper strip to be laminated 5, the current flows out from the positive electrode of the power supply component 130 electrically connected to this strip to be laminated 5, flows into the upper conductive roller 1211 connected to the positive electrode through a wire, then enters the upper strip to be laminated 5 through the contact point between the conductive roller and the upper strip to be laminated 5, then flows from the upper strip to be laminated 5 into another upper conductive roller 1211 on the upper side connected to the negative electrode of the power supply component 130, and finally returns to the negative electrode of this power supply component 130 through a wire, forming a conductive loop for the upper strip to be laminated 5; for the lower strip to be laminated 5, the current flows out from the positive electrode of the power supply component 130 electrically connected to this strip to be laminated 5, flows into the lower conductive roller 1221 connected to the positive electrode through a wire, enters the lower strip to be laminated 5 through the contact point between the conductive roller and the lower strip to be laminated 5, then flows from the lower strip to be laminated 5 into another conductive roller on the lower side connected to the negative electrode of this power supply component 130, and finally returns to the negative electrode of the power supply component 130 through a wire, forming a conductive loop for the lower strip to be laminated 5.

[0058] With such a setting, in the two separately formed conductive circuits, the current is conducted through the contact between the conductive roller and the strip 5 to be compounded. Utilizing the thermal effect generated by the current, the deformation resistance of the material of different strips 5 to be compounded is reduced during their respective conductive processes, and the atomic diffusion rate is accelerated. When different strips 5 to be compounded come into contact with each other, the atoms of different strips 5 to be compounded can be more effectively fused, completing the compounding process of the strip 5 to be compounded. This way of forming conductive circuits on different strips 5 to be compounded can more precisely control the current action on each strip 5 to be compounded, contributing to improving the quality and stability of strip compounding.

[0059] It should be noted that for ease of understanding, as Figure 5 and Figure 6 shown, the moving direction of the strip 5 to be compounded relative to the current compounding roller system 120 is A, and the direction of the current is B.

[0060] As a possible embodiment, please refer to Figure 1 , the box body 110 includes an upper box body 111 and a lower box body 112, the upper box body 111 and the lower box body 112 are detachably connected, the upper roller group 121 is arranged on the upper box body 111, and the lower roller group 122 is arranged on the lower box body 112.

[0061] Specifically, the box body 110 is composed of the detachable connection of the upper box body 111 and the lower box body 112 to form the structure of the box body 110, providing a stable outer frame for the entire device. The power supply component 130 is arranged inside the structure of the box body 110, and the upper roller group 121 and the lower roller group 122 are respectively arranged on the upper box body 111 and the lower box body 112. With such a setting, the upper roller group 121 and the lower roller group 122 are respectively arranged on the upper box body 111 and the lower box body 112. When the strip 5 to be compounded passes through the conductive roller, the pressures on both sides of the side-by-side strips 5 to be compounded are more balanced, avoiding the situation of inconsistent deformation of the strip 5 to be compounded caused by uneven force, which is beneficial to improving the flatness and quality of the compound strip. The symmetrically arranged conductive rollers cooperate with the power supply component 130 inside the box body 110, enabling the current to be more evenly distributed on the strip 5 to be compounded. Due to the uniform conduction of the current, it promotes the more uniform compounding of the strip 5 to be compounded at the atomic level, solves the problem of poor material deformation coordination ability, and improves the bonding strength of the compound strip.

[0062] Furthermore, the upper box body 111 and the lower box body 112 are fixedly connected by bolts to form a closed and stable frame structure. Compared with a single integral frame, this design makes the assembly of the equipment more reasonable, and the overhaul and maintenance more convenient. When internal components need to be maintained, the upper box body 111 or the lower box body 112 can be opened separately, facilitating the quick positioning of components and saving maintenance time and costs.

[0063] Further, a number of observation windows 1110 are installed on the upper box body 111. The observation windows 1110 are made of a transparent material with a certain strength, such as transparent materials like glass, so as to monitor the operation of the oil removal roller system.

[0064] Further, please refer to Figure 1 , the pressing component 140 is fixedly arranged on one side edge position of the upper box body 111 close to the conductive roller group. The pressing component 140 can adopt various forms such as a hydraulic cylinder, an electric cylinder or a manual pressing component 140, so as to apply a stable and adjustable pressure to the upper box body 111, thereby better enabling the conductive roller group to be in close contact with the strip to be laminated 5 and improving the lamination effect of the strip to be laminated 5.

[0065] As a possible implementation manner, as Figure 4 shown, the power supply component 130 includes an electric control box 131 and a brush 132. The electric control box 131 is arranged inside the box body 110. The electric control box 131 is electrically connected to the upper conductive roller 1211 and the lower conductive roller 1221 through the brush 132. The brushes 132 are arranged in an axial array along the upper conductive roller 1211 and the lower conductive roller 1221, and are in sliding contact with the surfaces of the upper conductive roller 1211 and the lower conductive roller 1221.

[0066] Specifically, the power supply component 130 includes an electric control box 131 and a brush 132. The electric control box 131 is arranged inside the structure of the box body 110 and establishes an electrical connection with the conductive roller through the brush 132. The brushes 132 are distributed in an axial array along the conductive roller and are in sliding contact with the surface of the conductive roller. This connection method ensures uniform and stable power supply.

[0067] During specific implementation, the electric control box 131 generates current. The current is transmitted to the conductive roller through the brush 132. Since the brushes 132 are arranged in an axial array along the conductive roller and are in sliding contact with the surface of the conductive roller, the current can be evenly distributed on the conductive roller, and the sliding contact method will not affect the normal rotation of the conductive roller. When the strip to be laminated 5 is transmitted above the conductive roller, the current on the conductive roller and the strip to be laminated 5 form an electrical conduction loop. Under the action of the current, the strip to be laminated 5 realizes current lamination. In some embodiments, the material of the conductive roller is steel, and the material of the insulating roller is ceramic.

[0068] It should be noted that the current generated by the electric control box 131 can be pulsed current, direct current or alternating current, and the form of the current is not limited herein.

[0069] As a possible implementation manner, as Figure 3As shown in the figure, the strip composite device 1 further includes a cooling roll system 150. The cooling roll system 150 is located at the outlet end of the current composite roll system 120. The cooling roll system 150 includes an upper cooling roll group 151, a lower cooling roll group 152, a first driving mechanism 153 and a cooling box 154. Among them, the upper cooling roll group 151 and the lower cooling roll group 152 are arranged opposite to each other on the box body 110. The upper cooling roll group 151 includes a plurality of upper cooling rolls 1511 arranged in parallel. The lower cooling roll group 152 includes a plurality of lower cooling rolls 1521 arranged in parallel. Both the upper cooling rolls 1511 and the lower cooling rolls 1521 contain a first cooling medium. The upper cooling rolls 1511 and the lower cooling rolls 1521 are used to contact the strip to be composite 5 for temperature reduction. The first driving mechanism 153 is arranged on the box body 110. The driving end of the first driving mechanism 153 is connected to the upper cooling rolls 1511 and the lower cooling rolls 1521, and is used to drive the upper cooling rolls 1511 and the lower cooling rolls 1521 to rotate. The cooling box 154 is fixedly arranged on the box body 110. The cooling box 154 contains a second cooling medium. Through holes are formed on the box body 110, and the through holes are used for the second cooling medium to enter the box body 110.

[0070] During specific implementation, when the strip to be composite 5 is completed in the current composite roll system 120, due to the thermal effect of the current, the temperature of the strip to be composite 5 rises, and then it enters the area of the cooling roll system 150. At this time, driven by the first driving mechanism 153, the cooling rolls start to rotate. The strip to be composite 5 contacts the cooling rolls on its upper and lower sides. Since the cooling rolls contain a first cooling medium and the temperature of the cooling rolls is lower than that of the strip to be composite 5, heat will be transferred from the strip to be composite 5 to the cooling rolls, thereby realizing the temperature reduction of the strip to be composite 5. With such a setting, the strip to be composite 5 after composite can be cooled in time, and problems such as deformation or oxidation of the strip to be composite 5 caused by high temperature can be avoided, the composite quality of the strip to be composite 5 can be guaranteed, and the strip to be composite 5 can reach the temperature required for subsequent processing or storage faster, thereby improving the efficiency of the entire production process.

[0071] In some embodiments, the cooling roller has a hollow structure, and there are external water pipes at both ends of the cooling roller. By introducing cold water into the cooling roller, the temperature of the cooling roller is made lower than that of the strip to be laminated 5, so as to achieve the effect of cooling by contacting the strip to be laminated 5. In some other embodiments, a phase change material can also be filled in the hollow structure of the cooling roller. When the strip to be laminated 5 contacts the cooling roller, the heat of the strip to be laminated 5 causes the phase change material to change from a solid state to a liquid state, absorbing a large amount of latent heat, thereby achieving the cooling of the strip to be laminated 5. After the phase change material absorbs heat and changes from a solid state to a liquid state, it can be cooled and re-solidified by a cooling device installed on the box body 110 so as to absorb heat again to achieve the effect of repeated use, and this method has a good cooling effect and can achieve a stable cooling capacity. In addition, a specific heat dissipation fin structure can also be provided on the surface of the cooling roller, and a fan is installed at a suitable position on the box body 110. When the laminated strip to be laminated 5 passes through the cooling roller, the fan starts, and the air flows through the surface of the cooling roller with heat dissipation fins, and exchanges heat with the fins on the surface of the cooling roller, taking away the heat absorbed by the cooling roller from the strip to be laminated 5, so as to achieve the heat exchange cooling of the strip to be laminated 5. This method does not require the introduction of a coolant inside the cooling roller, reduces potential problems such as coolant leakage, and is relatively simple and easy to maintain.

[0072] It should be noted that the cooling box 154 is fixedly arranged on the box body 110, the cooling box 154 contains a second cooling medium, and through holes are provided on the box body 110 for the second cooling medium to enter the box body 110.

[0073] Specifically, when the strip to be laminated 5 passes through the current lamination roller system 120 to complete lamination and then enters the cooling roller system 150, the cooling medium in the cooling box 154 flows from the medium channel led out of the cooling box 154 and into the area of the cooling roller through the through holes opened on the upper box body 111. Through the convective heat transfer between the cooling medium and the laminated strip, the rapid cooling of the laminated strip is effectively achieved, avoiding problems such as deformation or oxidation of the laminated strip caused by high temperature, and ensuring the quality of the laminated strip.

[0074] It is worth mentioning that the number of cooling boxes 154 in the cooling roller system 150 is two and they are symmetrically arranged on the top of the upper box body 111. A cooling medium is added inside the box body 110, and the cooling medium can be liquid nitrogen, carbon dioxide or water, etc. Multiple groups of bent pipe nozzles are arranged at intervals at the front end of the box body 110, and the ends of the nozzles correspond to the through holes of the upper box body 111. The cooling medium is evenly sprayed into the area of the cooling roller through the nozzles, achieving the rapid cooling of the laminated thin strip.

[0075] It should be noted that please refer to Figures 7 - 8, the first driving mechanism 153 includes a first driving motor and a double-worm multi-wormwheel synchronous transmission mechanism. This mechanism includes a segmented lower worm shaft 1532 and an upper worm shaft 1531, and each segment of the worm gear ring meshes with the corresponding wormwheel respectively. The lower worm shaft 1532 and the upper worm shaft 1531 are in meshing transmission through a first gear 1533, a first bearing gear 1535, a second bearing gear 1536, and a second gear 1534, and the module and number of teeth of all gears and bearing gears are the same. Both ends of the worm shaft are supported by the machine frame. The worm motor 1538 is connected to the lower worm shaft 1532, and the cooling roller is connected to the wormwheel 1537 through a key to achieve synchronous rotation of the upper and lower cooling rollers 1521. Among them, the first driving motor is fixedly arranged on the box body 110, and the driving end of the first driving motor is connected to the first bearing gear 1535 or the second bearing gear 1536 to drive the transmission of the entire double-worm multi-wormwheel synchronous transmission mechanism. With such a setting, through the multi-stage transmission of gears and worm gears, only a single worm motor is required to drive multiple pairs of cooling rollers to rotate synchronously, reducing the number of motors and improving the transmission stability.

[0076] Among them, for easy understanding, please refer to Figure 9 , the transmission principle diagram of the double-worm multi-wormwheel synchronous transmission mechanism is shown in the figure. Among them, c is the meshing transmission diagram of the first gear 1533, the first bearing gear 1535, the second bearing gear 1536, and the second gear 1534.

[0077] As a possible implementation, as Figure 10 shown, the strip composite device 1 further includes an oil removal roller system 160. The oil removal roller system 160 is arranged on the side of the cooling roller system 150 away from the current composite roller system 120. The oil removal roller system 160 includes an upper oil removal roller group 161, a lower oil removal roller group 162, and a second driving mechanism 163. Among them, the upper oil removal roller group 161 and the lower oil removal roller group 162 are arranged oppositely on the box body 110. The upper oil removal roller group 161 includes a plurality of upper oil removal rollers 1611 arranged in parallel; the lower oil removal roller group 162 includes a plurality of lower oil removal rollers 1621 arranged in parallel. The second driving mechanism 163 is arranged on the box body 110, and the driving end of the second driving mechanism 163 is connected to the upper oil removal roller 1611 and the lower oil removal roller 1621 to drive the upper oil removal roller 1611 and the lower oil removal roller 1621 to rotate. The oil removal roller system 160 is used to prevent the oil in the twenty-high rolling mill from entering the strip composite device 1.

[0078] Specifically, the oil removal roller system 160 is arranged on the side of the cooling roller system 150 away from the current composite roller system 120. In the composite of the strip to be composite 5, the strip to be composite 5 first passes through the current composite roller system 120 to complete the composite, then undergoes a temperature reduction treatment through the cooling roller system 150, and finally reaches the oil removal roller system 160. With such a setting, it is possible to prevent the lubricating oil in the multi-high rolling mill from flowing into the strip composite device 1 and avoid the high-temperature strip in the device from contacting the oil, resulting in combustion.

[0079]

[0079] When actually implemented, after the composite strip after being composite comes out of the cooling roll system 150, it enters the degreasing roll system 160. At this time, the second driving mechanism 163 installed on the box body 110 starts to work, and the driving end drives the upper degreasing roll 1611 and the lower degreasing roll 1621 to rotate in a direction away from the cooling roll system 150. The rotating upper degreasing roll 1611 and lower degreasing roll 1621 are respectively in contact with the upper and lower surfaces of the composite strip. During the working process of the multi-roll mill, the oil inside it may be brought into the strip composite device 1 along with the movement of the composite strip and adhere to the surface of the composite strip. The high-speed rotating degreasing roll uses centrifugal force. When the composite strip comes into contact with the high-speed rotating degreasing roll, under the action of centrifugal force, the oil is thrown off from the surface of the composite strip, thus achieving the degreasing effect.

[0080]

[0080] It should be noted that since the strip composite device 1 provided by the present invention is used to achieve a pre-composite effect on the strip to be composite 5 before it enters the multi-roll mill, in order to ensure the precise transmission of the composite strip, the box body 110 of the strip composite device 1 is also provided with a protruding structure. This protruding structure is arranged on one side of the degreasing roll system 160 on the box body 110, and is used to extend into the multi-roll mill so that the strip composite device 1 can be accurately docked with the multi-roll mill and play a guiding role, ensuring that the composite strip can smoothly and accurately enter the multi-roll mill from the strip composite device 1. In addition, the protruding structure is located on one side of the degreasing roll system 160, which can block the flow of the oil in the multi-roll mill towards the strip composite device 1 to a certain extent, and cooperate with the degreasing roll system 160 to prevent the oil from entering the strip composite device 1.

[0081]

[0081] Further, please refer to Figure 11 Figure 11 , oil-absorbing sleeves 164 are sleeved on the surfaces of the upper degreasing roll 1611 and the lower degreasing roll 1621. The upper degreasing roll 1611 and the lower degreasing roll 1621 are both of hollow structure, and oil holes 16110 are opened on the surfaces of the upper degreasing roll 1611 and the lower degreasing roll 1621.

[0082] Specifically, an oil absorption sleeve 164 is provided on the surface of the oil removal roller. The oil absorption sleeve 164 is made of a material with oil absorption properties, such as an oil-loving sponge material or activated carbon. Oil holes 16110 are provided on the surface of the oil removal roller. The oil captured by the oil absorption sleeve 164 can enter the hollow structure of the oil removal roller through the oil holes 16110, and then the oil is discharged from both ends of the oil removal roller. The oil holes 16110 are arranged in an array along the axial and circumferential directions of the oil removal roller on the surface of the oil removal roller, so that there are multiple uniform oil inlet channels on the oil removal roller, increasing the oil removal efficiency. In specific implementation, when the composite strip passes through the oil removal roller, the oil removal roller with the oil absorption sleeve 164 on its surface starts to work. The oil absorption sleeve 164 made of a material with oil absorption properties can capture the oil on the surface of the composite strip by virtue of its physical properties. As the oil removal roller rotates, the oil captured by the oil absorption sleeve 164 will, under the action of centrifugal force and its own gravity, be partly thrown out of the strip composite device 1, and the other part will move towards the direction of the oil holes 16110. Due to the existence of the oil holes 16110, the oil on the oil absorption sleeve 164 can enter the hollow structure of the oil removal roller. The oil entering the hollow structure will, under the action of the centrifugal force generated by the continuous rotation of the oil removal roller, transfer along the hollow structure to both ends of the oil removal roller. Finally, the oil is discharged from both ends of the oil removal roller, completing the entire oil removal process. In this process, the rotation of the oil removal roller provides power for the transfer and discharge of the oil. The oil absorption sleeve 164, the oil holes 16110 and the hollow structure cooperate with each other to prevent the oil from entering the strip composite device 1 and contacting the high-temperature composite strip, resulting in combustion.

[0083] It should be noted that, please refer to Figure 10 , the second driving mechanism 163 includes a second driving motor and a belt transmission mechanism. In the belt transmission mechanism, the belt pulley driving motor outputs power to drive the second belt pulley to rotate. The second belt pulley is connected to the motor through a coupling to ensure stable power transmission. The second belt pulley then drives the first belt pulley to rotate through a belt, realizing power transmission. Since the first lower oil removal roller is connected to the first belt pulley through a flat key, and the second lower oil removal roller is connected to the second belt pulley through a flat key, the flat key can stably transmit the torque of the belt pulley to the oil removal roller, thereby driving the first lower oil removal roller and the second lower oil removal roller to rotate and complete the oil throwing work.

[0084] As a possible implementation, as Figure 2 or Figure 12 shown, the strip composite device 1 further includes a guiding assembly 170. The guiding assembly 170 is arranged at the inlet end of the strip composite device 1. The guiding assembly 170 includes a guiding roller system 171, a guiding plate 172 and a guiding bracket 173. The guiding bracket 173 is fixedly connected to the strip composite device 1. The guiding roller system 171 is arranged on the guiding bracket 173 and is used to guide the transmission direction of the strip 5 to be composite. The guiding plate 172 is fixedly arranged on the guiding bracket 173 and is located at the inlet end of the guiding roller system, and is used to guide the strip 5 to be composite into the guiding roller system.

[0085] During specific implementation, when the strip 5 to be compounded is released from the uncoiler 2 and passes through the guiding roller system 171 before entering the current compounding roller system 120, due to the rotatable characteristics of the guiding rollers in the guiding roller system 171, when the strip 5 to be compounded contacts the guiding rollers, the guiding rollers will rotate as the strip 5 to be compounded moves, thereby guiding the strip 5 to be compounded to be transmitted to the strip compounding device 1 in a predetermined direction. During the transmission of the strip 5 to be compounded, the guiding plate 172 located below the guiding rollers plays a role. The guiding plate 172 vertically limits the strip 5 to be compounded, preventing the strip 5 to be compounded from shifting up and down during transmission, and ensuring that the strip 5 to be compounded is always transmitted within a stable vertical plane. With such a setting, through the setting of the guiding component 170, it can be ensured that the strip 5 to be compounded is accurately transmitted from the uncoiler 2 to the strip compounding device 1, avoiding problems such as deviation of the strip 5 to be compounded during transmission, ensuring the stability and continuity of the transmission of the strip 5 to be compounded, and improving production efficiency. The vertical limiting effect of the guiding plate 172 on the strip 5 to be compounded enables the strip 5 to be compounded to maintain a stable posture during transmission, which is beneficial for the subsequent strip compounding device 1 to perform precise compounding treatment on the strip 5 to be compounded, improving the quality of the compounded strip and reducing compounding defects caused by the unstable position of the strip 5 to be compounded.

[0086] It can be understood that since different strips are compounded by the current compounding roller system 120 and then cooled and degreased by the cooling roller system 150 and the degreasing roller system 160 respectively, the strip is the strip 5 to be compounded before being compounded by the current compounding roller system 120 and becomes the compounded strip after being compounded by the current compounding roller system.

[0087] As Figure 2 shown, the embodiment of the present specification also provides a compound strip rolling system, which includes:

[0088] Any of the above strip compounding devices 1, any of the above tension adjusting devices 3, and the twenty-high rolling mill 4, wherein the tension adjusting device 3, the strip compounding device 1, and the twenty-high rolling mill 4 are arranged in sequence to complete the rolling of the compound strip.

[0089] As a possible implementation manner, please refer to Figure 13 , the strip compound rolling system further includes a tension adjusting device 3, the tension adjusting device 3 is arranged between the uncoiler 2 and the strip compounding device 1, and the tension adjusting device 3 includes: a bracket, a floating tension roller 32, and a third driving mechanism 33; wherein, the floating tension roller 32 is arranged on the bracket, and the floating tension roller 32 is used to contact the strip to adjust the tension of the strip; the third driving mechanism 33 is arranged on the bracket, and the third driving mechanism 33 is used to drive the floating tension roller 32 to move to drive the strip.

[0090] During specific implementation, during the transmission of the strip, the strip contacts the floating tension roller 32 arranged on the bracket. At this time, the third driving mechanism 33 arranged on the bracket starts to drive the floating tension roller 32 to move. When the floating tension roller 32 moves, the strip in contact with it will also be driven accordingly. Specifically, when the third driving mechanism 33 drives the floating tension roller 32 to move, the strip can be stretched, thereby increasing the tension of the strip. By controlling the moving direction and distance of the floating tension roller 32 through the third driving mechanism 33, the precise adjustment of the strip tension can be realized. To ensure the stability of the tension of the two strips when entering the pre-lamination device, the lamination quality of the laminated strip is improved.

[0091] As a possible implementation, as Figure 13 shown, the floating tension roller 32 includes a first tension roller 321, a second tension roller 322 and a third tension roller 323, and the third driving mechanism 33 includes a lead screw motor 331, a driving motor 332 and a lead screw slider mechanism 333; wherein, the first tension roller 321 and the second tension roller 322 are relatively fixedly arranged on the bracket, the driving motor 332 is fixedly arranged on the bracket, and the driving end of the driving motor 332 is connected to the first tension roller 321 and the second tension roller 322 for driving the first tension roller 321 and the second tension roller 322 to rotate; the lead screw slider mechanism 333 is arranged on the bracket, the third tension roller 323 is arranged on the slider of the lead screw slider mechanism 333, the lead screw motor 331 is fixedly arranged on the bracket, and the driving end of the lead screw motor 331 is connected to the lead screw of the lead screw slider mechanism 333 for driving the lead screw to rotate and driving the third tension roller 323 to move closer to or away from the first tension roller 321 and the second tension roller 322 along the axial direction of the lead screw.

[0092] During specific implementation, the driving motor 332 works, and its driving end drives the first tension roller 321 and the second tension roller 322 to rotate. The strip contacts these two tension rollers during the transmission process. As the first tension roller 321 and the second tension roller 322 rotate, the strip is driven forward. When it is necessary to adjust the tension of the strip, the lead screw motor 331 starts, drives the lead screw to rotate, the rotation of the lead screw will drive the slider to move along the axial direction of the lead screw, and then drive the movement of the third tension roller 323 arranged on the slider. The movement of the slider will make the third tension roller 323 closer to or away from the first tension roller 321 and the second tension roller 322. When the third tension roller 323 moves away from the first tension roller 321 and the second tension roller 322, the tensile force received by the strip increases, so the tension increases, thereby realizing the adjustment of the strip tension. With such a setting, the position of the third tension roller 323 is precisely controlled through the lead screw motor 331 and the lead screw slider mechanism 333, the precise adjustment of the strip tension is realized, the stability of the strip tension during the transmission and processing is ensured, and the stable and appropriate strip tension helps to avoid problems such as slack or breakage of the strip during the transmission process, thereby improving the processing quality of the laminated strip.

[0093] It should be noted that the floating tension roller 32 in the tension adjusting device 3 adopts a concave roller design, and the concave roller can play a role in limiting the composite thin strip to ensure that the thin strip remains aligned during transmission.

[0094] In the description of the above embodiments, the specific features, structures, materials or characteristics can be combined in a suitable manner in any one or more embodiments or examples.

[0095] As mentioned above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
