Technical Field

[0001] The utility model relates to the technical field of unwinding equipment, in particular to a coil guiding device. Background Art

[0002] A storage battery is a device that converts chemical energy into electrical energy. With the improvement of storage battery production technology, the degree of equipment automation has increased, and the production efficiency has increased. More and more batteries begin to use grid plates. Usually, the coiled connection grid plates need to be flattened before entering the coating station for coating operations. The existing coiled connection grid plates need to be manually flattened by people before entering the coating station, which greatly affects the subsequent production speed of the grid plates. Therefore, there is an urgent need for a coil guiding device to solve the above problems. Summary of the Utility Model

[0003] In order to solve the technical problem that the existing coiled connection grid plates need to be manually flattened by people before entering the coating station, the utility model provides a coil guiding device, which can realize the transmission of the connection grid plates and flatten the connection grid plates.

[0004] The utility model provides a coil guiding device, which includes a rotating disk and a guiding mechanism arranged in sequence along the moving direction of the coil. The rotating disk is rotatably arranged on the frame. The guiding mechanism includes a pressure roller and a plurality of guiding rollers rotatably arranged on the frame, and the pressure roller is located between the rotating disk and the plurality of guiding rollers. The guiding rollers are arranged obliquely, and the included angle between the guiding rollers and the ground gradually decreases from the end close to the rotating disk to the end far from the rotating disk. The guiding roller farthest from the rotating disk is parallel to the ground. The coil, that is, the coiled connection grid plates, is transmitted to the coating station through the rotating disk and the guiding mechanism.

[0005] Further, a cross connecting rod is obliquely arranged on the frame. The height of the horizontal plane where the end of the cross connecting rod close to the rotating disk is located is greater than the height of the horizontal plane where the end of the cross connecting rod far from the rotating disk is located. A plurality of roller frames are fixedly connected to the cross connecting rod. The included angle between the roller frames and the ground gradually decreases from the end close to the rotating disk to the end far from the rotating disk. The roller frame farthest from the rotating disk is parallel to the ground. Both ends of each guiding roller are rotatably arranged on both side walls of the roller frame through a first bearing. The guiding roller rotates on the roller frame through a first bearing seat, and the guiding roller is obliquely fixed on the cross connecting rod through the roller frame.

[0006] Further, screws are fixedly connected to both ends of the cross connecting rod. Two nut seats are oppositely arranged on the frame and are arranged at different heights. Each screw is fixedly connected to the nut seat through a fixing nut. After the screw is threadedly connected to the nut seat, it is locked to the nut seat through the fixing nut, so as to realize that the cross connecting rod is fixed on the frame through the screw and the nut seat.

[0007] Further, shielding sheets are provided on both side walls of each roller frame, and the shielding sheets are located outside the guide rollers. There is a gap between each shielding sheet and the guide roller. The shielding sheet can guide the connecting sheet grid passing through the gap and also prevent the connecting sheet grid from falling off the guide roller.

[0008] Further, a gasket is sleeved on each guide roller. The gasket prevents the guide roller from causing wear to the connecting sheet grid during the transmission of the connecting sheet grid.

[0009] Further, the guiding mechanism further includes an arc-shaped frame provided on the frame. The arc-shaped frame is provided on the side away from the rotating disk and is located downstream of the guide roller. A plurality of transmission rollers are evenly and rotatably provided on the arc-shaped frame. The plurality of transmission rollers further transmit the flattened connecting sheet grid.

[0010] Further, the coiled material guiding device further includes a tensioning mechanism. The tensioning mechanism is located on the side of the guiding mechanism away from the rotating disk. The tensioning mechanism includes a tensioning frame and a tensioning roller. The tensioning frame is provided on the outside of one side of the frame. A cylinder is provided on the tensioning frame, and the telescopic rod of the cylinder is fixedly connected to the tensioning plate through a connecting rod. Both ends of the tensioning roller are rotatably provided on the tensioning plate through second bearings. The flattened connecting sheet grid finally enters the coating station in a tensioned state after being transmitted through the tensioning roller.

[0011] Compared with the prior art, the present utility model has the following technical effects:

[0012] The coiled material, that is, the coiled connecting sheet grid, is transmitted to the coating station through the rotating disk and the guiding mechanism. The coiled connecting sheet grid is sleeved on the fixed shaft of the rotating disk. At this time, the coiled connecting sheet grid is perpendicular to the ground. After the rotating disk rotates, the connecting sheet grid is unrolled, and the unrolled connecting sheet grid is transmitted through the pressure roller and a plurality of guide rollers. The pressure roller and the plurality of guide rollers transmit and support the connecting sheet grid. Since the included angle between the plurality of guide rollers and the ground gradually decreases from the end close to the rotating disk to the end away from the rotating disk, the connecting sheet grid is parallel to the ground after being transmitted through the plurality of guide rollers, that is, the connecting sheet grid is flattened. The flattened connecting sheet grid can then enter the coating station for coating operations, thereby improving the production speed of the grid. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0025] As Figures 1 to 6 shown, a coiled material guiding device includes a rotating disk 1 and a guiding mechanism 2 arranged in sequence along the moving direction of the coiled material. The rotating disk 1 is rotatably arranged on the machine frame 4, and a fixed shaft 11 is arranged on the rotating disk 1. The guiding mechanism 2 includes a pressing roller 21 and a plurality of guiding rollers 22 rotatably arranged on the machine frame 4, and the pressing roller 21 is located between the rotating disk 1 and the plurality of guiding rollers 22. The plurality of guiding rollers 22 are all arranged obliquely, and the included angles formed between the plurality of guiding rollers 22 and the ground gradually decrease from the end close to the rotating disk 1 to the end far from the rotating disk 1. The guiding roller 22 farthest from the rotating disk 1 is parallel to the ground. Among them, the rotating disk 1 is perpendicular to the ground, the pressing roller 21 is perpendicular to the ground, and the included angles formed between the plurality of guiding rollers 22 and the ground gradually decrease from the end close to the rotating disk 1 to the end far from the rotating disk 1.

[0026] The coiled material, i.e., the coiled connected plate grids, is transported to the coating station through the rotating disk 1 and the guiding mechanism 2. The coiled connected plate grids are sleeved on the fixed shaft 11 of the rotating disk 1. At this time, the coiled connected plate grids are perpendicular to the ground. After the rotating disk 1 rotates, the unwinding of the connected plate grids is realized, and the unwound connected plate grids are transported through the pressure roller 21 and a plurality of guiding rollers 22. The pressure roller 21 and the plurality of guiding rollers 22 transport and support the connected plate grids. Since the included angle between the plurality of guiding rollers 22 and the ground gradually decreases from the end close to the rotating disk 1 to the end far from the rotating disk 1, the connected plate grids are parallel to the ground after being transported through the plurality of guiding rollers 22, that is, the connected plate grids are flattened. The flattened connected plate grids can then enter the coating station for coating operations, thereby improving the production speed of the plate grids.

[0027] The coiled material guiding device of this embodiment can realize the transportation of the connected plate grids and flatten the connected plate grids.

[0028] As an implementable manner, a cross connecting rod 23 is inclinedly arranged on the frame 4. The height of the horizontal plane where the end of the cross connecting rod 23 close to the rotating disk 1 is located is greater than the height of the horizontal plane where the end of the cross connecting rod 23 far from the rotating disk 1 is located. A plurality of roller frames 24 are fixedly connected to the cross connecting rod 23. The included angle between the roller frames 24 and the ground gradually decreases from the end close to the rotating disk 1 to the end far from the rotating disk 1. The roller frame 24 farthest from the rotating disk 1 is parallel to the ground. Both ends of each guiding roller 22 are rotatably arranged on the two side walls of the roller frame 24 through the first bearings. Since the coiled material guiding device of this embodiment and the coating station may not be at the same horizontal height, after the cross connecting rod 23 is inclinedly arranged, firstly, it is beneficial to flatten the connected plate grids. Secondly, the cooperation of the cross connecting rod 23 and the plurality of guiding rollers 22 can make the connected plate grids flatten more quickly. The guiding roller 22 rotates on the roller frame 24 through the first bearing seat, and the guiding roller 22 is inclinedly fixed on the cross connecting rod 23 through the roller frame 24. Assuming that both the roller frames 24 and the guiding rollers 22 are set to nine, the included angles between the nine roller frames 24 and the ground can be designed as 85°, 75°, 65°, 55°, 45°, 35°, 25°, 15° and 0°.

[0029] As an implementable manner, a pressure roller bearing seat is arranged on the frame 4, and the cross connecting rod 23 and the bearing seat are arranged oppositely. The pressure roller 21 is rotatably connected to the pressure roller bearing seat. The pressure roller 21 rotates through the pressure roller bearing seat.

[0030] As an implementable mode, the coil guiding device further includes a motor. A main bearing seat is provided on the frame 4, and the main bearing seat is rotationally connected to the main shaft. One end of the main shaft is fixedly connected to the output shaft of the motor, and the other end of the main shaft is fixedly connected to the rotating disk 1. When the motor is started, it drives the main shaft to rotate on the main bearing seat, and then drives the rotating disk 1 to rotate. Since the coiled connected plate grids are sleeved on the fixed shaft 11 of the rotating disk 1, after the rotating disk 1 rotates, the unwinding of the connected plate grids is realized.

[0031] As an implementable mode, screw rods 231 are fixedly connected to both ends of the cross link 23. Two nut seats 41 are oppositely arranged on the frame 4, and the two nut seats 41 are arranged at different heights. Each screw rod 231 is fixedly connected to the nut seat 41 through a fixing nut. After the screw rod 231 is threadedly connected to the nut seat 41, it is locked to the nut seat 41 through the fixing nut, and then the cross link 23 is fixed to the frame 4 through the screw rod 231 and the nut seat 41. When the position of the screw rod 231 in the nut seat 41 is adjusted, the position of the cross link 23 on the frame 4 is adjusted, that is, after the inclination height of the cross link 23 is adjusted, it is further beneficial for the connected plate grids to enter different coating stations after being flattened.

[0032] As an implementable mode, shielding pieces 241 are provided on both side walls of each roller frame 24, and the shielding pieces 241 are located outside the guiding rollers 22. A gap exists between each shielding piece 241 and the guiding roller 22. The shielding pieces 241 can guide the connected plate grids passing through the gap and prevent the connected plate grids from falling off the guiding rollers 22.

[0033] As an implementable mode, gaskets are sleeved on each guiding roller 22. The gaskets prevent the guiding rollers 22 from causing wear to the connected plate grids during the transmission of the connected plate grids.

[0034] As an implementable mode, the guiding mechanism 2 further includes an arc-shaped frame 25 provided on the frame 4. The arc-shaped frame 25 is arranged on the side far from the rotating disk 1 and is located downstream of the guiding rollers 22. A plurality of driving rollers 26 are evenly and rotatably arranged on the arc-shaped frame 25; wherein, the driving rollers 26 are rotationally arranged on the arc-shaped frame 25 through third bearings. The plurality of driving rollers 26 further transmit the flattened connected plate grids, enabling the flattened connected plate grids to have a stable transition and ensuring that the flattened connected plate grids can smoothly enter the coating station.

[0035] As an implementable mode, the coil guiding device further includes a tensioning mechanism 3, which is located on one side of the guiding mechanism 2 away from the rotating disk 1. The tensioning mechanism 3 includes a tensioning frame 31 and a tensioning roller 32. The tensioning frame 31 is arranged on the outer side of the machine frame 4. A cylinder 33 is arranged on the tensioning frame 31, and the telescopic rod of the cylinder 33 is fixedly connected with a tensioning plate 34 through a connecting rod. Both ends of the tensioning roller 32 are rotatably arranged on the tensioning plate 34 through second bearings. To ensure that the flattened joint plate grid can smoothly enter the coating station, a plurality of driving rollers 26 transfer the flattened joint plate grid. Then, the cylinder 33 is started to drive the tensioning plate 34 and the tensioning roller 32 to move up and down. After being transferred by the tensioning roller 32, the flattened joint plate grid finally enters the coating station in a tensioned state. Among them, the way that the roller rotates through a bearing seat or a shaft is a prior art and will not be elaborated here.

[0036] As an implementable mode, the guiding mechanism 2 further includes a guiding seat arranged on the machine frame 4, which is located on one side of a plurality of guiding rollers 22 close to the rotating disk 1. A channel is arranged on the guiding seat. After the rotating disk 1 rotates, the joint plate grid is unrolled, and the unrolled joint plate grid is transferred through the channel on the guiding seat, the pressure roller 21 and a plurality of guiding rollers 22. The arrangement of the guiding seat further ensures that the joint plate grid can be smoothly flattened.

[0037] The above embodiments are only the preferred embodiments of the present invention, which are only used to explain the present invention and do not limit the scope of implementation of the present invention. For those skilled in the art of this technology, of course, other implementation modes can be easily made by means of replacement or change according to the technical content disclosed in this specification. Therefore, all changes and improvements made in the principle and process conditions of the present invention should be included within the scope of the patent application of the present invention.
