Description

Technical Field

[0001] This utility model relates to the field of irregular copper strip processing technology, and in particular to an irregular copper strip floating paper liner device. Background Technology

[0002] In the production process of shaped copper alloy strip, the tension leveler is one of the core pieces of equipment. The complete process involves extruding copper rods to a molten state through an extruder, then extruding them through a specific mold, followed by multiple rolling, annealing, cleaning, slitting, tension leveling, and packaging processes to finally obtain the finished shaped copper strip. However, the paper liner device in the current tension leveling process of shaped copper strip has revealed many significant shortcomings in practical applications.

[0003] Existing paper-lining devices struggle to achieve uniform paper lining on the surface of irregularly shaped copper strips. Due to the slight misalignment that forms during winding, the "T"-shaped area between the packaging paper and the copper strip surface is not fully covered, resulting in slanted lining or even slippage. For example, with traditional paper-lining methods, the angle of the lining paper is fixed while the winding machine floats, leading to uneven lining, with some sides having more lining than others, failing to accurately cover the "T"-shaped area and even causing slippage. This uneven lining easily causes scratches and abrasions on the surface of the irregularly shaped copper strip, severely affecting its quality and performance. It may even lead to issues like chip detachment after subsequent stamping and packaging due to surface scratches, posing a safety hazard to the customer. This is especially problematic if the chip is ultimately used in industries like new energy vehicles, where chip detachment during vehicle operation could easily cause traffic accidents.

[0004] Different specifications of irregularly shaped copper strips vary in width, thickness, and "T"-shaped sections, requiring the lining device to have good dimensional adaptability. However, most existing lining devices use fixed structures or simple adjustment methods, making it difficult to flexibly adapt to different sizes of irregularly shaped copper strips. When producing irregularly shaped copper strips of different specifications, key parameters such as the lining area, lining force and angle, and paper distribution of the lining device often cannot be adjusted in a timely and accurate manner. For example, for narrower irregularly shaped copper strips, existing lining devices may have excessively large winding ranges, resulting in packaging paper not fully covering the "T"-shaped area of ​​the irregularly shaped copper strip, leading to low lining efficiency. Conversely, for wider irregularly shaped copper strips, the "T" shape is also wider, and excessively large winding ranges may also prevent packaging paper from effectively covering the entire surface of the irregularly shaped copper strip, resulting in slanted lining or lining outside the copper roll, severely affecting the product's aesthetics and quality. This also affects the lining effect. This lack of dimensional adaptability limits the versatility and production efficiency of the lining device, increasing the company's equipment investment and production costs.

[0005] Therefore, we propose a novel floating copper strip liner device to address the shortcomings of existing technologies and improve liner quality and production efficiency. Utility Model Content

[0006] This utility model provides a floating copper strip paper liner device that overcomes the shortcomings of the prior art and can effectively solve the problems of existing fixed-structure paper liner devices that cannot be adjusted to have oblique or slipping liner.

[0007] To solve the above problems, the present invention provides a floating copper strip paper liner device, comprising: a bottom box, a drive device, a winding machine, a paper liner device, and a position detector. A motor reducer housing is slidably connected to the top of the bottom housing. A paper lining device is located on the left side of the motor reducer housing. The paper lining device includes a frame, a paper lining motor, a base plate, a coupling, a bearing seat, and an air shaft. Two frames are fixedly fixed at intervals on the bottom left side of the motor reducer housing. The bottom ends of the two frames are fixedly connected to the base plate. Bearing seats and a paper lining motor are fixedly installed on the base plate at intervals. The output shaft of the paper lining motor is connected to a coupling. An air shaft is located in front of the bearing seat. The rear end of the air shaft passes through the bearing seat and connects to the coupling. Packaging paper is fitted on the outside of the air shaft. A winding machine is located on the front side of the motor reducer housing; A drive unit is located at the center of the rear side of the motor reducer housing. The drive unit includes an outer cylinder of a hydraulic cylinder, an inner cylinder of a hydraulic cylinder, and a fixed frame. A fixed frame is located at the center of the rear side of the bottom housing. An outer cylinder of a hydraulic cylinder is fixedly installed on the front side of the upper part of the fixed frame. An inner cylinder of a hydraulic cylinder is fitted inside the outer cylinder of the hydraulic cylinder. The front end of the inner cylinder of the hydraulic cylinder is fixedly connected to the rear side of the motor reducer housing. A position detector is connected between the upper front side of the fixed bracket located below the outer cylinder of the hydraulic cylinder and the center of the rear side of the motor reducer housing.

[0008] The top of the aforementioned bottom housing has two slide rails fixed at intervals on the left and right. The bottom of the motor reducer housing corresponding to the slide rail position has a slide groove that matches the slide rail. Each slide rail is located inside the slide groove at the corresponding position.

[0009] Both of the aforementioned keel frames are inverted "L" shape.

[0010] The aforementioned mounting bracket is L-shaped.

[0011] The outer side of the aforementioned hydraulic cylinder is provided with an oil inlet and an oil outlet that are connected internally and externally at intervals.

[0012] This invention utilizes a floating winding machine and a keel frame to enable the device to move back and forth between the hydraulic cylinder and the motor reducer housing when the irregularly shaped copper strip is being wound in staggered layers. This creates a floating winding above the slide rail, resulting in neatly stacked copper coils. The motor reducer housing then moves synchronously with the paper lining device via the keel frame. As the copper coils float back and forth, the paper lining device also floats synchronously, ensuring that the packaging paper is always placed within the "T"-shaped area of ​​the irregularly shaped copper strip, preventing slanted or slipping lining.

[0019] This utility model is not limited to the following embodiments, and the specific implementation method can be determined according to the technical solution of this utility model and the actual situation.

[0020] The present invention will be further described below with reference to the embodiments and accompanying drawings: like Figure 1-4 As shown, a floating copper strip paper liner device includes: a bottom box 1, a drive unit, a winding machine 5, a paper liner device, and a position detector 11; A motor reducer housing 7 is slidably connected to the top of the bottom housing 1. A paper lining device is provided on the left side of the motor reducer housing 7. The paper lining device includes a frame 12, a paper lining motor 13, a base plate 14, a coupling 15, a bearing seat 16, and an air shaft 3. Two frames 12 are fixedly fixed at a distance from front to back on the bottom left side of the motor reducer housing 7. The bottom ends of the two frames 12 are fixedly connected to the base plate 14. The bearing seat 16 and the paper lining motor 13 are fixedly installed at a distance from front to back on the base plate 14. The output shaft of the paper lining motor 13 is connected to the coupling 15. An air shaft 3 is provided in front of the bearing seat 16. The rear end of the air shaft 3 passes through the bearing seat 16 and is connected to the coupling 15. Packaging paper 2 is fitted on the outside of the air shaft 3. A winding machine 5 is located on the front side of the motor reducer housing 7; A drive unit is provided at the center of the rear side of the motor reducer housing 7. The drive unit includes an outer hydraulic cylinder 9, an inner hydraulic cylinder 8, and a fixed frame 10. A fixed frame 10 is provided at the center of the rear side of the bottom housing 1. The outer hydraulic cylinder 9 is fixedly installed on the front side of the upper part of the fixed frame 10. The inner hydraulic cylinder 8 is fitted inside the outer hydraulic cylinder 9. The front end of the inner hydraulic cylinder 8 is fixedly connected to the rear side of the motor reducer housing 7. A position detector 11 is connected between the upper front side of the fixing bracket 10 located below the outer cylinder 9 of the hydraulic cylinder and the center of the rear side of the motor reducer housing 7.

[0021] The position detector 11 is a known E-Series EL00100MD341A01 displacement sensor. The position detector 11 is used to provide feedback on the real-time position of the motor gearbox. In use, the position detector 11 is connected to an external control device (which can be a PLC). The operator calibrates the zero position of the position detector 11 through the external control device, calibrating the intermediate position of the position detector 11. When the position detector 11 exceeds the intermediate position, a positive feedback signal is automatically triggered and returned to the external control device. When the position detector 11 is below the intermediate position, a negative feedback signal is automatically triggered and returned to the external control device. When the external control device receives the positive / negative feedback signal from the position detector 11, it sends a control signal to the intermediate relay, which in turn sends a current signal to the solenoid valve. Through the opening / closing of the solenoid valve, the hydraulic cylinder moves forward and backward / backward, thereby extending and retracting, and controlling the rewinder to float back and forth.

[0022] Therefore, by cooperating with the hydraulic cylinder and the position detector 11, the paper lining device and the winding machine 5 can be synchronized to ensure that the center position of the packaging paper lining is kept constant when it is fed into the shaped copper strip 6, thereby improving the paper lining efficiency of the paper lining device and ensuring that the "T" shaped surface of the shaped copper strip 6 is evenly covered, avoiding incomplete paper lining, slanted lining, slip lining and other situations.

[0023] The drive unit is used to control the floating of the motor reducer housing 7 by extending and retracting the inner cylinder 8 of the hydraulic cylinder when the device is winding the shaped copper strip 6 into a liner, thereby ensuring that the requirements of the copper coil tower layer are met.

[0024] The expansion and contraction of the air shaft 3 allows the device to accommodate packaging paper 2 of different specifications to be used with irregularly shaped copper strips 6 of different specifications.

[0025] In this system, the winding machine 5 and the paper-lining device work together to allow the paper-lining device to float and line the irregularly shaped copper strip 6 along with the winding machine 5. This ensures that the packaging paper 2 is neatly lined into the "T"-shaped surface of the irregularly shaped copper strip 6, thereby improving the paper-lining efficiency of the irregularly shaped copper strip 6, ensuring that the "T"-shaped surface of the irregularly shaped copper strip 6 is lined evenly, and avoiding situations where the paper is not completely lined.

[0026] The motor reducer housing contains a motor and a reducer. The motor reducer is connected to an external control device. The operator sends a control signal to the external control device, which then outputs a control signal to the frequency converter. The frequency converter outputs current, voltage, frequency, and other signals to control the motor to start / stop / accelerate / decelerate.

[0027] like Figure 1 , 2 As shown, two slide rails 4 are fixedly spaced on the top left and right of the bottom housing 1. The bottom of the motor reducer housing 7, corresponding to the position of the slide rail 4, is fixed with a groove that matches the slide rail 4. Each slide rail 4 is located inside the groove at the corresponding position. Thus, through the matching of the slide rail 4 and the groove, the motor reducer housing 7 can slide back and forth on the upper side of the bottom housing 1 under the action of the drive device, thereby realizing the adjustment of the position of the winding machine 5 and the paper liner device.

[0028] like Figure 1 , 2 As shown, both keel frames 12 are inverted "L" shapes. This facilitates the installation and fixation of the keel frames 12.

[0029] like Figure 2 , 3 As shown, the mounting bracket 10 is L-shaped. This facilitates the installation and fixation of the mounting bracket 10 and the connection between the mounting bracket 10 and the motor reducer housing 7.

[0030] like Figure 2 , 3 As shown, the outer cylinder 9 of the hydraulic cylinder has an inlet and an outlet that are spaced apart and run through it. Thus, by providing the inlet and outlet for the hydraulic oil to enter and exit within the outer cylinder 9, the inner cylinder 8 of the hydraulic cylinder can move back and forth.

[0031] The usage process of this utility model is as follows: The extension or retraction of the inner cylinder 8 of the hydraulic cylinder can be controlled by an external control device to meet the layer requirements of the copper strip tower. The drive motor reducer housing 7 floats back and forth on the slide rail 4, thereby driving the winding machine 5 to move back and forth. The keel frame 12 drives the base plate 14 to move back and forth, which in turn drives the air shaft 3 to move back and forth, causing the packaging paper 2 on the outer ring of the air shaft 3 to move back and forth. This linkage mechanism can ensure that the packaging paper 2 moves synchronously when the irregular copper strip 6 is floating and winding, so that the packaging paper 2 is always inserted into the "T" shaped surface inside the irregular copper strip 6. When the inner cylinder 8 of the hydraulic cylinder extends or retracts, the motor reducer housing 7 drives the position detector 11 to move back and forth. The position detector 11 has a calibrated center position area of ​​the winding machine 5. When the external control device sends the action of extending the inner cylinder 8 of the hydraulic cylinder, the inner cylinder 8 of the hydraulic cylinder extends, drives the motor reducer housing 7 to extend, drives the winding machine 5 to extend, and drives the paper liner device to extend. The position detector 11 transmits the real-time position of the motor reducer housing 7. When the inner cylinder 8 of the hydraulic cylinder continues to extend beyond the center position area calibrated by the position detector 11, the position detector 11 sends a negative feedback signal, and the external control device performs the action of retracting the inner cylinder 8 of the hydraulic cylinder. Similarly, when the external control device sends a retraction action to the inner cylinder 8 of the hydraulic cylinder, the inner cylinder 8 retracts, driving the motor reducer housing 7 to retract, which in turn drives the winding machine 5 to retract, and drives the paper lining device to retract. The position detector 11 transmits the real-time position of the motor reducer housing 7. When the inner cylinder 8 of the hydraulic cylinder continues to retract beyond the center position area calibrated by the position detector 11, the position detector 11 sends a positive feedback signal, and the external control device causes the inner cylinder 8 of the hydraulic cylinder to extend. This reciprocating action ensures that the packaging paper 2 is always lining the center of the shaped copper strip 6, i.e., the "T" shaped area.

[0032] In summary, this utility model, through the cooperation of the floating winding machine 5 and the keel frame 12, enables the device to achieve the required staggered winding of the irregularly shaped copper strip 6 during use. This is achieved by retracting the inner cylinder 8 of the hydraulic cylinder to drive the motor reducer housing 7 to move back and forth, forming a floating winding above the slide rail 4. This results in the copper roll forming a neat tower layer. Furthermore, the motor reducer housing 7 drives the paper lining device to move synchronously through the keel frame 12. As the copper roll floats back and forth, the paper lining device also floats synchronously, ensuring that the packaging paper 2 is always lining the "T"-shaped area of ​​the irregularly shaped copper strip 6, avoiding slanted or slipped lining.

[0033] Furthermore, this utility model, through the cooperation of the hydraulic cylinder and the position detector 11, enables the device to control the floating of the motor reducer housing 7 by extending and retracting the inner cylinder 8 of the hydraulic cylinder when winding the shaped copper strip 6 with liner paper. This ensures that the requirements of the copper coil tower layer are met. When the inner cylinder 8 of the hydraulic cylinder extends, if the winding deviates from the center range, the position detector 11 gives a negative feedback signal to the external control device, and the inner cylinder 8 of the hydraulic cylinder retracts, pulling the winding machine 5 to retract, thereby driving the liner paper device to retract. Similarly, when the inner cylinder 8 of the hydraulic cylinder retracts, if the winding deviates from the center range, the position detector 11 gives a positive feedback signal to the external control device, and the inner cylinder 8 of the hydraulic cylinder extends, pushing the winding machine 5 to extend, thereby driving the liner paper device to extend. This structure allows the lining device and the winding device to operate synchronously, ensuring that the center position of the packaging paper 2 remains constant when it is lined with the shaped copper strip 6, thereby improving the lining efficiency of the lining device and ensuring that the "T" shaped surface of the shaped copper strip 6 is evenly covered, avoiding incomplete lining coverage, slanted lining, slip lining, and other issues.
