Description

Technical Field

[0001] This invention relates to the field of stamping equipment, specifically to a rewinding and rewinding device for a material turnover tray. Background Technology

[0002] In the stamping process, a composite winding method of one layer of paper strip and one layer of raw material to be processed is widely used to form a raw material supply tray. The raw material to be processed in the raw material supply tray (such as copper strip, aluminum strip, and other metal strips) usually has a clear directionality. Taking copper strip as an example, ... Figure 3 As shown, it includes a functional raised surface on one side and a corresponding recessed surface on the other. However, there is an inherent contradiction in the material turnover process: when suppliers provide raw material supply trays, they usually wind the metal strip with the recessed surface facing the center of the raw material supply tray. However, in actual use on the production site, in order to ensure accurate material positioning and correct forming direction during the stamping process, the metal strip must ensure that its raised surface faces the center of the raw material supply tray when it enters the stamping equipment.

[0003] Therefore, during the production preparation stage, the initial raw material supply tray must be rewound. This involves rewinding the metal strip from the initial tray onto a new tray, and simultaneously performing alternating composite winding of paper strip and metal strip during the rewinding process, ensuring that the convex surface of the final wound metal strip faces the center of the raw material supply tray. Currently, the rewinding operation mainly relies on manual operation of simple unwinding and rewinding frames, with operators manually pulling the metal strip and paper strip for composite winding. This method is not only labor-intensive and inefficient, but also fails to simultaneously recover the paper strip separated from the initial raw material supply tray, resulting in a messy workshop environment. Summary of the Invention

[0004] The present invention aims to provide a rewinding device for a material turnover tray, so as to improve the problems of high labor intensity, low efficiency and inability to simultaneously recover the paper tape peeled off from the initial raw material supply tray by manual operation.

[0005] To solve the above technical problems, the specific solution adopted by the present invention is as follows: It includes a substrate, on which are provided a first limiting post, a second limiting post, a third limiting post, and a fourth limiting post. The first limiting post is used to rotatably mount the raw material supply disk on the substrate, the third limiting post is used to rotatably mount the paper tape supply disk on the substrate, the second limiting post is driven by the output shaft of a first drive motor and is used to mount a rewinding disk, and the fourth limiting post is driven by the output shaft of a second drive motor and is used to mount a paper tape collection disk. A winding path for the metal strip is formed between the raw material supply disk and the rewinding disk, a collection path for the original paper tape is formed between the raw material supply disk and the paper tape collection disk, and a winding path for the new paper tape is formed between the rewinding disk and the paper tape supply disk. By driving the rewinding disk and the paper tape collection disk to rotate by the first drive motor and the second drive motor respectively, the metal strip on the raw material supply disk and the new paper tape on the paper tape supply disk can be compoundly wound on the rewinding disk, while the original paper tape peeled off from the raw material supply disk is collected by the paper tape collection disk.

[0006] A further optimization of the rewinding device for a material turnover tray: the substrate is provided with a guide assembly for regulating the movement path of the metal strip, the original paper strip and the new paper strip. The guide assembly includes a guide plate and guide posts provided on the guide plate.

[0007] Further optimization of the rewinding and rewinding device for a material turnover tray: multiple guide posts are provided on the guide plate.

[0008] Further optimization of the rewinding device for a material turnover tray: guide rails are provided on the substrate at the positions corresponding to the original paper tape collection path and the metal strip winding path, the guide component is slidably mounted on the guide rail, and the guide component is fixed to the guide rail by locking bolts.

[0009] Further optimization of the rewinding device for a material turnover tray: the first drive motor is electrically connected to the first foot switch, and the second drive motor is electrically connected to the second foot switch.

[0010] A further optimization of the rewinding device for a material turnover tray: a first sensor is provided on the substrate at the position of the metal strip outlet of the raw material supply tray, and a second sensor is provided on the substrate at the position of the original paper strip outlet of the raw material supply tray.

[0011] As a further optimization of the rewinding device for a material turnover disk: both the second and fourth limit posts are equipped with turntable fixing components. The turntable fixing components include a moving block and a fixed block. The fixed block is fixed to the lower part of the corresponding second or fourth limit post, and the moving block is detachably provided on the upper part of the corresponding second or fourth limit post, which is used to clamp and fix the rewinding disk between the fixed block and the moving block.

[0012] Further optimization of the rewinding device for a material turnover tray: a frame is provided at the bottom of the substrate.

[0013] Beneficial Effects: This invention integrates the raw material supply tray, rewinding tray, paper tape supply tray, and paper tape collection tray onto the same substrate, achieving automated operation during the rewinding process where the metal strip rotates and is simultaneously collected from the original paper tape. During rewinding, the metal strip on the raw material supply tray is separated from the original paper tape simultaneously. The original paper tape is continuously peeled off and neatly collected under the traction of the paper tape collection tray. When the metal strip is transferred to the rewinding tray, because the rewinding tray and the raw material supply tray rotate in opposite directions, the metal strip can naturally rotate when it is wound onto the rewinding tray. At the same time, the rotated metal strip and the new paper tape on the paper tape supply tray are simultaneously wound onto the rewinding tray under the traction of the rewinding tray. This improves upon the problems of high labor intensity, low efficiency, and inability to simultaneously collect the paper tape peeled off from the raw material supply tray in manual operation.

[0016] Example 1

[0017] like Figure 1 As shown, a material turnover tray rewinding device includes a base plate 7, which serves as the mounting base for various components and ensures the stability of the overall structure. A frame 15 is provided at the bottom of the base plate 7 to support the base plate 7 and enable the device to adapt to different sites, providing a stable working environment for the device.

[0018] A first limiting post 2 and a third limiting post 9 are fixedly disposed on the substrate 7. The first limiting post 2 is used to rotatably mount the raw material supply tray 1, which carries the original composite roll material, that is, a layer of paper tape and a layer of metal strip 21 to be processed (in this embodiment, the metal strip 21 to be processed is copper strip) are alternately stacked and wound, and in this original state, the concave surface of the metal strip 21 faces the center of the tray. The third limiting post 9 is used to rotatably mount the paper tape supply tray 10, which has a clean new paper tape 8 pre-wound on it, for re-composite with the metal strip 21 after rewinding.

[0019] Combination Figure 2 As shown, the substrate 7 is also provided with a second limiting post 13 and a fourth limiting post 5. The lower end of the second limiting post 13 is connected to the output shaft of the first drive motor 14 installed at the bottom of the substrate 7, and a rewinding disc 12 is detachably mounted on the second limiting post 13. The lower end of the fourth limiting post 5 is connected to the output shaft of the second drive motor 23 installed at the bottom of the substrate 7, and a paper tape collecting disc 6 is detachably mounted on the fourth limiting post 5. The first drive motor 14 and the second drive motor 23 serve as independent power sources, driving the rewinding disc 12 and the paper tape collecting disc 6 to rotate respectively. The rotation speeds of the two can be independently adjusted according to actual process requirements (adjusting the motor speed is a conventional aspect of existing technology and will not be elaborated here), thereby achieving matching of different rotation speeds between the rewinding disc and the paper tape collecting disc.

[0020] To ensure smooth operation of the metal strip 21, the original paper strip 22, and the new paper strip 8 during the transfer process, a guide assembly 19 is also provided on the substrate 7. Specifically, the guide assembly 19 includes a guide plate 1901 and multiple guide posts 1902 disposed on the guide plate 1901. The guide assembly 19 is provided on the paths of the metal strip 21 from the raw material supply tray 1 to the rewinding tray 12, the original paper strip 22 from the raw material supply tray 1 to the paper strip collection tray 6, and the new paper strip 8 from the paper strip supply tray 10 to the rewinding tray 12. The guide posts 1902 have smooth surfaces, which effectively reduces the frictional resistance of the strips during travel and also helps to regulate the path and prevent deviation. To further enhance the adaptability to strips of different specifications and discs of different diameters, a guide rail 18 is provided on the substrate 7 at the position corresponding to the above path. The guide component 19 is slidably mounted on the guide rail 18 and fixed by the locking bolt 11, so that the position of the guide component 19 can be adjusted according to the actual situation.

[0021] The first drive motor 14 is electrically connected to the first foot switch 16, and the second drive motor 23 is electrically connected to the second foot switch 17. The operator can control the start and stop of the two motors by foot pedal, thereby flexibly adjusting according to the actual winding situation and realizing semi-automatic operation.

[0022] To ensure the stability of the rewinding disc 12 and the paper tape collecting disc 6 during high-speed rotation, both the second limiting post 13 and the fourth limiting post 5 are equipped with a turntable fixing assembly 4. The turntable fixing assembly 4 includes a fixed block 401 and a movable block 402. Taking the installation method of the second limiting post 13 and the rewinding disc 12 as an example, the fixed block 401 is fixed to the lower part of the second limiting post 13 to support the rewinding disc 12 from the bottom, while the movable block 402 is threadedly connected to the upper part of the second limiting post 13. During installation, the rewinding disc 12 is sleeved on the second limiting post 13 and placed on the fixed block 401. Then, the movable block 402 is tightened, so that the rewinding disc 12 is firmly clamped between the fixed block 401 and the movable block 402, thereby effectively preventing the rewinding disc 12 from axially shifting or radially shaking during rotation, ensuring the smoothness of the winding process and the neatness of the roll edge.

[0023] During operation, the operator first places the raw material supply tray 1, carrying the original composite roll, on the first limiting post 2, places the empty rewinding tray 12 on the second limiting post 13 and locks it with the turntable fixing component 4, places the paper tape supply tray 10, carrying the new paper tape 8, on the third limiting post 9, and places the empty paper tape collection tray 6 on the fourth limiting post 5 and locks it with the turntable fixing component 4. Then, the original paper tape 22 head on the raw material supply tray 1 is pulled out, passes around the guide component 19 on the corresponding path, and is fixed on the paper tape collection tray 6; at the same time, the metal strip 21 on the raw material supply tray 1 is peeled off from the original paper tape 22, passes around the corresponding guide component 19, and is fixed on the rewinding tray 12; then the new paper tape 8 on the paper tape supply tray 10 is pulled out, passes around the guide component 19, overlaps and aligns with the metal strip 21, and is fixed together on the rewinding tray 12. After starting the first drive motor 14 and the second drive motor 23, the rewinding disc 12 rotates to pull the metal strip 21 and the new paper strip 8 to wind synchronously. At the same time, the paper strip collection disc 6 rotates to pull the original paper strip 22 for peeling and recycling. During this process, when the metal strip 21 is transferred from the raw material supply disc 1 to the rewinding disc 12, its winding orientation naturally reverses, so that the convex surface that was not originally facing the center of the raw material supply disc 1 becomes facing the center on the rewinding disc 12, thereby realizing the automatic reversal of orientation. At the same time, the peeling and recycling of the original paper strip 22 and the synchronous composite winding of the new paper strip 8 are completed. Finally, a brand-new composite disc with one layer of new paper strip 8 and one layer of metal strip 21 alternately wound on the rewinding disc 12, and the convex surface of the metal strip 21 facing the center, is obtained. Example 2

[0024] This embodiment is an optimization based on Embodiment 1.

[0025] like Figure 1As shown, a first sensor 20 is installed on the substrate 7 at the outlet of the metal strip 21 of the raw material supply tray 1, and a second sensor 3 is installed on the substrate 7 at the outlet of the paper tape of the raw material supply tray 1. The two sensors are respectively connected to the control circuits of the first drive motor 14 and the second drive motor 23. Both the first sensor 20 and the second sensor 3 are photoelectric sensors. When the metal strip 21 or the original paper tape 22 passes normally, the sensor is blocked, and the first drive motor 14 and the second drive motor 23 operate normally. When the metal strip 21 or the original paper tape 22 breaks, deviates, or has insufficient margin, the sensor is unblocked, the controller receives the abnormal signal, and controls the corresponding motor to stop, thus realizing automated operation.
