[0035] In order to solve the problem of the processing quality defect of the composite current collector material in the prior art, the present application provides a rolling equipment.

[0036] As Figures 1 to 3The utility model provides a kind of roller pressing equipment including rack, winding assembly 10 and unwinding assembly 20 being set on rack, roller pressing assembly 30 and detection assembly 40 shown in the figure.Winding assembly 10 and unwinding assembly 20 are used to transport the piece 1 to be rolled.Winding assembly 10 and unwinding assembly 20 are used to transport the piece 1 to be rolled.Roller pressing assembly 30 is arranged between winding assembly 10 and unwinding assembly 20, and roller pressing assembly 30 includes at least two rotatably arranged pressure rollers 31, and the at least two pressure rollers 31 are oppositely arranged to form a roller pressing gap around, and the roller pressing gap is used to roll the piece 1 to be rolled in the conveying process.Detection assembly 40 is arranged between roller pressing assembly 30 and winding assembly 10, and detection assembly 40 includes tool structure 41 and cooperating roller 42, and cooperating roller 42 is rotatably arranged, and the cutting edge of tool structure 41 is oppositely arranged with cooperating roller 42 to form a detection space around, and at least part of the piece 1 to be rolled is located in the detection space.

[0037] In the roller pressing equipment, winding assembly 10 and unwinding assembly 20 arranged on the rack are used to transport the piece 1 to be rolled.Roller pressing assembly 30 is arranged between winding assembly 10 and unwinding assembly 20, and roller pressing assembly 30 includes at least two rotatably arranged pressure rollers 31, and the at least two pressure rollers 31 are oppositely arranged to form a roller pressing gap around, and the roller pressing gap is used to roll the piece 1 to be rolled in the conveying process.Detection assembly 40 is arranged between roller pressing assembly 30 and winding assembly 10, and detection assembly 40 includes tool structure 41 and cooperating roller 42, and cooperating roller 42 is rotatably arranged, and the cutting edge of tool structure 41 is oppositely arranged with cooperating roller 42 to form a detection space around, and at least part of the piece 1 to be rolled is located in the detection space, and the interface table 50 arranged between detection assembly 40 and winding assembly 10 is used for the piece 1 to be rolled to be broken to perform the joint operation.In this way, during the conveying process of winding assembly 10 and unwinding assembly 20 to the piece 1 to be rolled, roller pressing assembly 30 can continuously roll the piece 1 to be rolled in the conveying process to ensure that most of the surface quality of the piece 1 to be rolled can meet the corresponding processing requirements.Meanwhile, detection assembly 40 located between roller pressing assembly 30 and winding assembly 10 can detect the surface quality of the piece 1 to be rolled after rolling, that is, if the surface quality of the piece 1 to be rolled is unqualified (the thickness of the piece 1 to be rolled is greater than the detection height), the cutting edge of tool structure 41 can cut the piece 1 to be rolled, so that the staff can subsequently find the position of the unqualified thickness of the piece 1 to be rolled, thereby ensuring that the surface quality of the piece 1 to be rolled can completely meet the corresponding processing requirements, and thus solving the problem of the processing quality defect of the composite current collector material in the prior art.Meanwhile, the staff can perform the joint operation on the interface table 50 after the piece 1 to be rolled is broken, and cut off the piece 1 to be rolled with unqualified thickness, so as to ensure that the piece 1 to be rolled can completely meet the corresponding processing requirements, and make the roller pressing equipment continue to run quickly.

[0038] In the embodiment, the piece 1 to be rolled is a composite current collector.

[0039] Specifically, the worker can cut off the position with unqualified thickness (the cutting distance is about 10mm) while performing the splicing operation on the to-be-rolled piece 1, so as to remove the part with quality defects of the to-be-rolled piece 1, and thus improve the processing quality of the to-be-rolled piece 1.

[0040] It should be noted that the structure of the docking table 50 is relatively conventional, and thus is not described herein.

[0041] Optionally, the detection space has a rolling height H1, and the detection space has a detection height H2, and the rolling height H1 and the detection height H2 satisfy 1.1H1≤H2≤1.5H1. In this way, the above arrangement ensures that the detection height H2 can match the thickness of the to-be-rolled piece 1 after rolling, and thus improves the detection accuracy of the detection assembly 40.

[0042] As shown in Figure 3 At least one of the matching roller 42 and the tool structure 41 is movably arranged on the rack, so as to adjust the size of the detection height H2 when one of the matching roller 42 and the tool structure 41 moves towards or away from the other one of the matching roller 42 and the tool structure 41, or when the matching roller 42 and the tool structure 41 move towards or away from each other. In this way, the above arrangement can adjust the detection height H2 to adapt to to-be-rolled pieces 1 of different specifications and sizes, and thus improves the detection versatility of the detection assembly 40, thereby improving the versatility of the rolling equipment. On the other hand, the adjustment mode of the detection height H2 is more flexible and diverse to adapt to different working conditions and use requirements, and also improves the processing flexibility of the worker.

[0043] In the embodiment, the tool structure 41 is movably arranged on the rack, and the tool structure 41 moves towards or away from the matching roller 42.

[0044] Optionally, the rack is provided with a mounting structure (which can be formed by welding a plurality of connecting plates, or can be an integral molding structure or a cast part, which is not described herein) for mounting the tool structure 41, a screw rod is threadedly connected to the mounting structure, and the tool structure 41 is arranged on the screw rod to be driven by the screw rod to move up and down. Meanwhile, a micrometer (which can also be carried by the worker himself) can be arranged on the mounting structure to confirm the height adjustment accuracy of the tool structure 41, and thus ensure that the detection height H2 has high adjustment accuracy.

[0045] Optionally, the rack is provided with a servo motor and a screw nut mechanism, the tool structure 41 is arranged on the nut of the screw nut mechanism, and the servo motor is drivingly connected to the screw rod of the screw nut mechanism to drive the nut to drive the tool structure 41 to move up and down, and thus adjust the size of the detection height H2.

[0046] In an embodiment not shown in the drawings, the cooperating roller is arranged to be raised and lowered on the frame, and the cooperating roller is moved towards or away from the knife structure.

[0047] In an embodiment not shown in the drawings, the cooperating roller and the knife structure are both arranged to be raised and lowered on the frame, and the cooperating roller and the knife structure are moved towards or away from each other.

[0048] As shown in Figure 1 and Figure 2 , the roller pressing device further comprises a driving device 60, at least one pressing roller 31 is movably arranged, and the driving device 60 is drivingly connected with the pressing roller 31 to adjust the size of the roller pressing height H1 when the driving device 60 drives the pressing roller 31 to move towards or away from the other pressing roller 31. In this way, the above arrangement can adjust the roller pressing height H1 on the one hand to adapt to different specifications and sizes of the workpiece 1 to be pressed, improve the universality of the roller pressing assembly 30, and thus improve the universality of the roller pressing device; on the other hand, the number of movable pressing rollers 31 can be more flexible and diverse to adapt to different working conditions and use requirements, and also improve the processing flexibility of the workers.

[0049] In this embodiment, the lower pressing roller 31 in the roller pressing assembly 30 is arranged to be raised and lowered.

[0050] In this embodiment, the driving device 60 is a hydraulic system, which can provide a continuous and stable driving force to the pressing roller 31 to ensure that the pressing roller 31 can continuously and stably press the workpiece 1 to be pressed, thereby improving the roller pressing reliability of the roller pressing assembly 30.

[0051] As shown in Figure 1 and Figure 2 , the roller pressing device further comprises a roller gap adjusting structure 70, which is arranged on the frame and at least part of the roller gap adjusting structure 70 is located in the roller gap; wherein the roller gap adjusting structure 70 is used to limit and stop the pressing roller 31 during the adjustment of the roller pressing height H1. In this way, the roller gap adjusting structure 70 can limit and stop the pressing roller 31, thereby improving the adjustment accuracy of the roller pressing height H1, and further improving the processing quality of the workpiece 1 to be pressed.

[0052] Specifically, although the hydraulic system can provide a continuous and stable pressure to the pressing roller 31, its control accuracy is poor and cannot guarantee that the driving pressing roller 31 can accurately move to the preset position. Therefore, the embodiment additionally provides the roller gap adjusting structure 70 to ensure that the roller pressing height H1 can be accurately adjusted by limiting and stopping.

[0053] As shown in Figure 1 and Figure 2As shown, the roller gap adjustment structure 70 is movably provided with a limiting inclined surface, which is used to limit and stop the pressure roller 31. The roller pressing equipment also includes a drive structure, which is mounted on the frame and is driven to the roller gap adjustment structure 70 through a transmission assembly, so as to drive the roller gap adjustment structure 70 to move toward or away from the roller gap. In this way, the above configuration realizes the automated movement of the roller gap adjustment structure 70 through the drive structure and transmission assembly, improving the automation level of the roller pressing equipment; on the other hand, by simply driving the roller gap adjustment structure to move toward or away from the roller gap, the pressure roller 31 can be limited and stopped at different positions with the limiting inclined surface, thereby increasing the height adjustment range of the roller gap adjustment structure 70 and improving the versatility of the roller gap adjustment structure 70.

[0054] In this embodiment, the roller gap adjustment structure 70 is a wedge.

[0055] In this embodiment, the driving structure is a motor.

[0056] In this embodiment, the transmission component is a lead screw and nut mechanism.

[0057] like Figure 1 As shown, the rolling mill also includes a guide roller 80. The guide roller 80 is rotatably mounted on the frame and located between the winding assembly 10 and the unwinding assembly 20. The guide roller 80 is used for winding the workpiece 1 to be rolled. There are multiple guide rollers 80. Along the conveying direction of the workpiece 1 to be rolled, the guide roller 80 adjacent to the pressure roller 31 is an adjusting roller 81. The adjusting roller 81 is vertically adjustable so as to adjust the wrap angle between the workpiece 1 to be rolled and the pressure roller 31 when the adjusting roller 81 drives the workpiece 1 to be rolled in contact with it to move up and down. In this way, the above-mentioned arrangement supports the workpiece 1 to be rolled during the conveying process through multiple rollers 80, thereby avoiding deformation of the workpiece 1 during the conveying process. This not only improves the surface tension stability of the workpiece 1 to be rolled, but also improves the transmission stability of the workpiece 1 to be rolled. On the other hand, by adjusting the wrap angle between the workpiece 1 to be rolled and the pressure roller 31 through the adjusting roller 81, the angle at which the workpiece 1 to be rolled enters the rolling gap can be adjusted, thereby improving the rolling reliability and stability of the rolling assembly 30 and further improving the processing quality of the workpiece 1 to be rolled.

[0058] In this embodiment, two adjusting rollers 81 are provided, located on both sides of the pressure roller 31 respectively.

[0059] In this embodiment, the adjusting roller 81 is vertically adjustable. The specific structure for achieving the vertical adjustment is not described in detail. For example, a servo motor can be used to drive a lead screw and nut mechanism to move the mounting plate vertically. The adjusting roller 81 and a motor for driving the adjusting roller 81 to rotate can be set on the mounting plate.

[0060] It should be noted that the number of adjusting rollers 81 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of adjusting rollers 81 can be three, four, six, seven or more.

[0061] In this embodiment, there are two rollers 80 located between the unwinding assembly 20 and the rolling assembly 30.

[0062] It should be noted that the number of guide rollers 80 located between the unwinding assembly 20 and the rolling assembly 30 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of guide rollers 80 located between the unwinding assembly 20 and the rolling assembly 30 can be three, four, six, seven or more.

[0063] In this embodiment, five rollers 80 are provided between the roll forming assembly 30 and the winding assembly 10.

[0064] It should be noted that the number of guide rollers 80 located between the roll forming assembly 30 and the winding assembly 10 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of guide rollers 80 located between the roll forming assembly 30 and the winding assembly 10 can be three, four, six, seven, nine or more.

[0065] like Figure 1 As shown, the winding assembly 10 includes a winding roller 11, the unwinding assembly 20 includes an unwinding roller 21, and the rolling equipment further includes a tension detection roller 90 and a control module. The tension detection roller 90 is rotatably mounted on the frame and located between the winding assembly 10 and the unwinding assembly 20. The tension detection roller 90 is used for winding the workpiece 1 to be rolled and includes a roller shaft and a pressure sensor mounted on the roller shaft. The pressure sensor detects the surface tension of the workpiece 1 by detecting the pressure applied by the workpiece 1 to the roller shaft. The control module is connected to the pressure sensor, the winding roller 11, and the unwinding roller 21. The control module controls at least one of the following based on the detection value of the pressure sensor: the rotational speed, direction, torque output, or operating power of the winding roller 11; and / or, the control module controls at least one of the following based on the detection value of the pressure sensor: the rotational speed, direction, torque output, or operating power of the unwinding roller 21. In this way, the control module can adjust the speed and torque output of the take-up roller 11 and the unwind roller in real time based on the detection values ​​of the pressure sensor, so as to ensure that the workpiece 1 to be rolled has sufficiently high tension stability during the conveying and rolling process, thereby further improving the conveying reliability of the workpiece 1 to be rolled. At the same time, the above settings also improve the intelligence level of the rolling equipment, thereby reducing the labor intensity of the workers and improving their work efficiency.

[0066] In the embodiment, the winding assembly 10 further comprises a motor, the motor is in driving connection with the winding roller 11 to drive the winding roller 11 to rotate, and the control module is connected with the motor to control the rotating speed of the winding roller 11 by controlling the rotating speed of the motor.

[0067] In the embodiment, the unwinding assembly 20 further comprises a motor, the motor is in driving connection with the unwinding roller 21 to drive the unwinding roller 21 to rotate, and the control module is connected with the motor to control the rotating speed of the unwinding roller 21 by controlling the rotating speed of the motor.

[0068] Specifically, the roller pressing equipment further comprises an alarm device, the control module is connected with the pressure sensor and the alarm device, so that when the detection value of the pressure sensor reaches the first preset value, the control module controls the alarm device to operate; and / or an encoder, which is arranged on the passing roller 80 and is used to detect the conveyed length of the to-be-rolled piece 1, the control module is connected with the encoder and the alarm device, so that when the detection value of the encoder reaches the second preset value, the control module controls the alarm device to operate. In this way, on the one hand, the control module controls the alarm device to alarm according to the detection value of the pressure sensor, so that the staff can respond in time, the real-time feedback function of the roller pressing equipment is realized, and the conveying smoothness of the to-be-rolled piece 1 is improved; on the other hand, the conveying length of the to-be-rolled piece 1 is recorded through the encoder, so that the staff can monitor the conveying length of the to-be-rolled piece 1 in real time, the staff can be reminded to replace the to-be-rolled piece 1 in time when the to-be-rolled piece 1 is conveyed, the automation degree of the roller pressing equipment is further improved, the labor intensity of the staff is reduced, and the work efficiency of the staff is improved.

[0069] Specifically, the first preset value of the pressure sensor has two values, one is zero, that is, when the detection assembly 40 detects that the thickness of the to-be-rolled piece 1 is unqualified and cuts off, the surface tension of the to-be-rolled piece 1 is zero, at this time, the alarm device alarms to remind the staff to timely splice the to-be-rolled piece 1, and the other is the maximum tension value that the to-be-rolled piece 1 can bear, that is, when the detection assembly 40 detects that the surface tension value of the to-be-rolled piece 1 is the maximum tension value that it can bear, the alarm device alarms to remind the staff to overhaul and adjust, so as to avoid the to-be-rolled piece 1 from being broken.

[0070] Specifically, the second preset value is actually determined by the total length of the to-be-rolled piece 1, that is, when the detection value of the encoder reaches the second preset value, the to-be-rolled piece 1 approaches the end of the conveying, at this time, the alarm device alarms to remind the staff to replace the next roll of to-be-rolled piece 1.

[0071] In the embodiment, the encoder is a rotary encoder, which measures the rotating number of the unwinding assembly to measure the conveying length of the to-be-rolled piece 1.

[0072] Optionally, the alarm device is a buzzer and / or an LED light.

The cleaning assembly 100 is arranged at one side of the compression roller 31 and comprises a scraper structure 101 and a collecting structure 102. The scraper structure 101 is in contact with at least part of the outer circumferential surface of the compression roller 31 to scrape off impurities on the compression roller 31 during rotation of the compression roller 31. The collecting structure 102 has a collecting cavity in communication with the outside, and the collecting structure 102 is arranged below the scraper structure 101 to collect impurities; and / or, the flattening roller 110 is rotatably arranged on the frame and used for winding the to-be-rolled piece 1 thereon. The flattening roller 110 is arranged between the rolling assembly 30 and the detection assembly 40; and / or, the pressing roller 120 is rotatably arranged on the frame and located between the detection assembly 40 and the winding assembly 10. The pressing roller 120 is movably arranged along the conveying direction of the to-be-rolled piece 1 to press the to-be-rolled piece 1 against the winding roller 11 of the winding assembly 10. In this way, the cleaning assembly 100 can clean the impurities on the compression roller 31 through the scraper structure 101, so as to avoid that the to-be-rolled piece 1 is damaged in the rolling process due to the impurities on the surface of the compression roller 31, thereby improving the processing quality of the to-be-rolled piece 1. On the other hand, the cleaning assembly 100 can collect the impurities on the compression roller 31 through the collecting structure 102, so as to avoid that the to-be-rolled piece 1 is contaminated due to the falling of the impurities on the to-be-rolled piece 1, thereby further improving the processing quality of the to-be-rolled piece 1. Meanwhile, the flattening roller 110 can flatten the to-be-rolled piece 1 before the to-be-rolled piece 1 enters the detection space, so as to avoid that the to-be-rolled piece 1 is wrinkled in the rolling or conveying process, thereby avoiding false detection of the detection assembly 40 and further improving the detection reliability of the detection assembly 40. Meanwhile, the to-be-rolled piece 1 is pressed against the winding roller 11 by the pressing roller 120, so as to improve the winding reliability of the winding assembly 10 and ensure the winding reliability of the winding assembly 10.

[0074] Specifically, the flattening roller 110 is actually arranged in a curved manner to flatten the to-be-rolled piece 1 while conveying the to-be-rolled piece 1.

[0075] In the embodiment, the rolling device further comprises a detection device 130 arranged below the unwinding roller 21, the detection device 130 detects the distance between the detection end and the remaining to-be-rolled piece 1 on the unwinding roller 21 to detect the remaining amount of the to-be-rolled piece 1 on the unwinding roller 21. The control module is connected with the detection device 130 and the unwinding roller 21, and controls the rotating speed of the unwinding roller 21 according to the detection value of the detection device 130 to adjust the surface tension value of the to-be-rolled piece 1 in the conveying process, and the control module further controls the rotating speed of the unwinding roller 21 or the size of the torque output of the unwinding roller 21 according to the detection value of the detection device 130, so that the tension stability of the to-be-rolled piece 1 is further improved.

[0076] Specifically, the use process of the rolling device is as follows:

[0077] The worker installs the to-be-rolled piece 1 on the unwinding roller 21, and winds one end of the to-be-rolled piece 1 through the roller 80, the adjusting roller 81 on one side of the compression roller 31, through the rolling gap to the adjusting roller 81 on the other side of the compression roller 31, and then through the roller 80, the tension detection roller 90 and the flattening roller 110, and then through the detection space, the connecting table 50, the roller 80 and the compression roller 120 to be wound on the winding roller 11.

[0078] When the rolling device works, the to-be-rolled piece 1 passes through the roller 80, the adjusting roller 81 on the unwinding roller 21, enters the rolling gap and is compression-rolled by the compression roller 31, and then passes through the adjusting roller 81, the roller 80, the tension detection roller 90 and the flattening roller 110 to enter the detection space and be detected by the detection assembly 40. When the detection assembly 40 detects that the to-be-rolled piece 1 is qualified, the to-be-rolled piece 1 passes through the connecting table 50, the roller 80 and the compression roller 120 to be collected into a material roll by the winding roller 11. At this time, the encoder records the length of the to-be-rolled piece 1 for the use of subsequent processes. When the detection assembly 40 detects that the to-be-rolled piece 1 is unqualified, the cutter structure 41 cuts the to-be-rolled piece 1. At this time, the tension detection roller 90 detects that the tension of the to-be-rolled piece 1 is abnormal and transmits the detection data to the control module. The control module controls the alarm device to alarm and reminds the worker to timely splice the broken to-be-rolled piece 1. The spliced to-be-rolled piece 1 passes through the roller 80 and the compression roller 120 to be collected into a material roll by the winding roller 11. At this time, the encoder records the length of the to-be-rolled piece 1 for the use of subsequent processes.

[0079] From the above description, it can be seen that the above-mentioned embodiments of the rolling device have the following technical effects:

[0080] The winding assembly and the unwinding assembly arranged on the frame in the rolling device are used to convey the to-be-rolled piece. The rolling assembly is arranged between the winding assembly and the unwinding assembly, and the rolling assembly comprises at least two rotatably arranged pressure rollers, the at least two pressure rollers are oppositely arranged to form a rolling gap, and the rolling gap is used to roll the to-be-rolled piece in the conveying process. The detection assembly is arranged between the rolling assembly and the winding assembly, and the detection assembly comprises a cutter structure and a matching roller, the matching roller is rotatably arranged, and the cutting edge of the cutter structure is oppositely arranged with the matching roller to form a detection space, at least part of the to-be-rolled piece is located in the detection space, and the connecting table arranged between the detection assembly and the winding assembly is used for the splicing operation of the broken to-be-rolled piece. In this way, in the conveying process of the to-be-rolled piece by the winding assembly and the unwinding assembly, the rolling assembly can continuously roll the to-be-rolled piece in the conveying process, so as to ensure that most of the surface quality of the to-be-rolled piece can meet the corresponding processing requirements. At the same time, the detection assembly located between the rolling assembly and the winding assembly can detect the surface quality of the to-be-rolled piece after rolling, that is, if the surface quality of the to-be-rolled piece is unqualified (the thickness of the to-be-rolled piece is greater than the detection height), the cutting edge of the cutter structure can cut the to-be-rolled piece, so that the staff can find the position of the unqualified thickness of the to-be-rolled piece in the subsequent process, so as to ensure that the surface quality of the to-be-rolled piece can completely meet the corresponding processing requirements, thereby solving the problem of the processing quality defect of the composite current collector material in the prior art. At the same time, the staff can splice the broken to-be-rolled piece on the connecting table and cut off the to-be-rolled piece with unqualified thickness, so as to ensure that the to-be-rolled piece can completely meet the corresponding processing requirements, and make the rolling device continue to run quickly.
