Description

Technical Field

[0001] This utility model belongs to the field of carbon-coated aluminum foil winding technology, specifically relating to a winding machine for carbon-coated aluminum foil. Background Technology

[0002] Carbon-coated aluminum foil is coated with a layer mainly composed of binders and conductive materials, exhibiting good oxidation resistance. When applied to batteries, it can reduce internal resistance, increase capacity, improve cycle performance and rate performance, and extend battery life. After preparation, the carbon-coated aluminum foil needs to be wound and transported for further processing.

[0003] Chinese patent document CN220283005U discloses a winding device for carbon-coated aluminum foil. The device uses a winding assembly on a mounting frame to allow the carbon-coated aluminum foil to be inserted into a fixed groove at one end for fixation. Then, a rotary motor drives the winding roller to rotate, thereby winding the carbon-coated aluminum foil.

[0004] However, in the existing technology, the ends of the winding roller with the fixed groove in the winding device are blocked by the mounting frame. Although it can wind carbon-coated aluminum foil, the ends of the carbon-coated aluminum foil are not firmly fixed in the fixed groove before and after winding, and it is difficult to take it out of the winding device easily. Therefore, a winding machine for carbon-coated aluminum foil is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a winding machine for carbon-coated aluminum foil.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A carbon-coated aluminum foil winding machine includes a winding assembly that can wind the carbon-coated aluminum foil strip at a required speed after operation. A material transfer assembly is provided on one side of the winding assembly to remove the wound carbon-coated aluminum foil roll. A contact assembly is provided above the material transfer assembly that can contact the carbon-coated aluminum foil at different positions in the winding machine so that it can be stably wound and easily removed.

[0008] The winding assembly includes a power box, and a winding drum is provided at the output end of the power box. The material transfer assembly includes a guide frame fixedly connected to one side of the power box.

[0010] The clamping component includes a first support rod fixedly connected inside the winding drum, a sliding frame movably mounted between the first support rods of the same height, a first spring provided between the first support rod and the sliding frame, and a clamping pad fixedly connected to the side of the sliding frame near the other sliding frame.

[0011] The separator includes a second support rod movably connected to the take-up drum, a support plate fixedly connected between the second support rods of the same height and longitudinal position, and a second spring provided between the take-up drum and the second support rod;

[0012] The limiting element includes a locking block that is movably connected to one side of the take-up drum.

[0033] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0034] like Figures 1-8 As shown, a carbon-coated aluminum foil winding machine includes a winding assembly 1 that can wind the carbon-coated aluminum foil strip at a required speed after operation. A transfer assembly 2 is provided on one side of the winding assembly 1 to remove the wound carbon-coated aluminum foil roll. A contact assembly 3 is provided above the transfer assembly 2 to contact the carbon-coated aluminum foil at different positions in the winding machine so that it can be stably wound and easily removed.

[0035] In this embodiment: the winding assembly 1 includes a power box 101, and a winding drum 102 is provided at the output end of the power box 101. The winding drum 102 has a hollow portion of a certain length, and the hollow portion has a notch.

[0036] The winding drum 102 is installed through the power box 101 and powered to rotate at the required speed. The winding drum 102 provides mounting positions for components such as the first support rod 301 and the second support rod 305, and drives these components to rotate together to stably wind up the carbon-coated aluminum foil.

[0037] In this embodiment: the material transfer assembly 2 includes a guide frame 201 fixedly connected to one side of the power box 101. Multi-stage hydraulic cylinders 202 are fixedly installed at the front and rear of the guide frame 201. A moving trolley 203 is fixedly connected between the telescopic ends of the multi-stage hydraulic cylinders 202. A vertical hydraulic cylinder 204 is fixedly installed above the moving trolley 203. A carrier frame 205 is fixedly connected between the telescopic ends of the vertical hydraulic cylinders 204. Rollers 206 are fixedly installed at the front and rear of the carrier frame 205.

[0038] The guide frame 201 provides installation positions for components such as the multi-stage hydraulic cylinder 202 and the moving trolley 203. By changing the length of the telescopic end of the multi-stage hydraulic cylinder 202, the moving trolley 203, whose movable range is limited by the guide frame 201, is moved laterally. The vertical hydraulic cylinder 204 adjusts the height difference between the carrier frame 205 and the moving trolley 203. The roller 206, which can rise and fall with the carrier frame 205 and move laterally with the moving trolley 203, provides support after contacting the carbon-coated aluminum foil roll.

[0039] In this embodiment, the contact component 3 includes a clamping member that can stably fix one end of the carbon-coated aluminum foil strip inside the winding drum 102, a separator that can keep the carbon-coated aluminum foil and the winding drum 102 at a certain distance so that the finished product can be taken out laterally, a limiting member that can stably wind the carbon-coated aluminum foil, and a lateral movement member that can adjust the lateral distance between the limiting member and the winding drum 102.

[0040] The clamping component includes a first support rod 301 fixedly connected inside the take-up drum 102. A sliding frame 302 is movably mounted between the first support rods 301 of the same height. A first spring 303 is provided between the first support rod 301 and the sliding frame 302. A clamping pad 304 is fixedly connected to the side of the sliding frame 302 near the other sliding frame 302. The separating component includes a second support rod 305 movably connected to the take-up drum 102. A support plate 306 is fixedly connected between the second support rods 305 of the same height and longitudinal position. A second spring 307 is provided between 02 and the second support rod 305. The limiting component includes a locking block 312 movably connected to one side of the take-up drum 102. The transverse component includes a transverse frame 308 movably installed in the guide frame 201. A transverse hydraulic cylinder 309 is fixedly connected to one side of the transverse frame 308. The limiting component includes a bending frame 310 movably connected to one end of the transverse frame 308. An inclined hydraulic cylinder 311 is provided between the other end of the transverse frame 308 and the bending frame 310. A locking block 312 is movably installed on the bending frame 310.

[0041] The take-up drum 102 and the first support rod 301 are slidably connected to the sliding frame 302. The take-up drum 102 is slidably connected to the second support rod 305. The take-up drum 102, the sliding frame 302, and the support plate 306 are all slidably connected to the locking block 312. The guide frame 201 is slidably connected to the transverse frame 308. The bending frame 310 and the inclined hydraulic cylinder 311 are rotatably connected to the transverse frame 308. The inclined hydraulic cylinder 311 and the locking block 312 are rotatably connected to the bending frame 310.

[0042] The movable range of the sliding frame 302 is limited by the first support rod 301 in conjunction with the take-up drum 102. The first spring 303 causes the two sliding frames 302, when not subjected to external force, to tend to move away from each other. Two clamping pads 304 contact different sides of the carbon-coated aluminum foil end to provide sufficient friction to fix the end of the carbon-coated aluminum foil without damaging it. A support plate 306 is mounted on the outside of the take-up drum 102 by a second support rod 305 that can pass through it. A second spring 307 causes the support plate 306, when not subjected to external force, to tend to move towards the take-up drum 102. A horizontally positioned hydraulic cylinder 3... 09 Adjust the lateral position of the transverse frame 308, which is connected to the lower end of the bending frame 310 and the tail end of the inclined hydraulic cylinder 311, within the guide frame 201. Adjust the inclination of the bending frame 310 by means of the inclined hydraulic cylinder 311. Install the locking block 312 on the bending frame 310 and drive it to move as needed. After contacting the winding drum 102, the locking block 312 seals the opening at the end of the winding drum 102 away from the power box 101 to improve its stability during rotation. The locking block 312 can also limit the positional changes of the sliding frame 302 and the support plate 306 by contacting the sliding frame 302 and the support plate 306.

[0043] Working principle: When this winding machine is installed for winding carbon-coated aluminum foil, the horizontal hydraulic cylinder 309 can be used to move the clamping block 312 horizontally to a position separated from the winding drum 102. Then, the operator passes one end of the carbon-coated aluminum foil through the winding drum 102 and places it between the two clamping pads 304. After placement, the horizontal hydraulic cylinder 309 can be activated again to push the clamping block 312 toward the winding drum 102. When the clamping block 312 contacts the winding drum 102 again, it will simultaneously contact the sliding frame 302 and the support plate 306, and push the two sliding frames 302 to move toward each other, so that the clamping pads 304 can clamp the carbon-coated aluminum foil, and push all the support plates 306 to move a certain distance away from the winding drum 102. Then, the power box 101 can be used to drive the winding drum 102 to rotate, and wind the carbon-coated aluminum foil onto each support plate 306.

[0044] After winding is completed, the horizontal hydraulic cylinder 309 and the inclined hydraulic cylinder 311 can be activated sequentially to separate the locking block 312 from the winding drum 102. The block then rotates with the bending frame 310 and flips into the guide frame 201. Next, the multi-stage hydraulic cylinder 202 drives the moving trolley 203 to move below the winding drum 102. When the idler roller 206, which moves horizontally with the moving trolley 203, is aligned with the wound carbon-coated aluminum foil roll, the vertical hydraulic cylinder 204 can be activated to lift the idler roller 206 to a position that can support the carbon-coated aluminum foil roll. When the locking block 312 separates from the take-up drum 102, the clamping pad 304 will no longer clamp the carbon-coated aluminum foil under the action of the first spring 303. The support plate 306 will move towards the take-up drum 102 due to the second spring 307 or the weight of the carbon-coated aluminum foil roll. Therefore, when the idler roller 206 lifts the carbon-coated aluminum foil roll, the innermost part of the carbon-coated aluminum foil roll will no longer contact the support plate 306. At this time, the guide frame 201 pushes the moving trolley 203 to reset, and the separation of the carbon-coated aluminum foil roll from the take-up drum 102 can be easily completed.

[0045] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
