Description

Technical Field

[0001] The present invention relates to the technical field of waste battery recycling, and particularly relates to a waste battery recycling skin-changing device. Background Art

[0002] The separator is one of the key components inside a cylindrical battery. Its main function is to provide physical isolation between the positive and negative electrodes to prevent short circuits, while allowing ions to pass through to maintain the electrochemical reaction. In the recycling of waste batteries, the original separator may experience performance degradation due to long-term use, aging, or damage. Continuing to use it may cause short circuits inside the battery, so the separator needs to be replaced with a plastic film.

[0003] Replacing the plastic film is divided into two steps: peeling and skin-changing. These two steps are carried out by two separate devices, with a relatively long travel distance. Larger and more complex conveying equipment must be used to support this process, thereby increasing the equipment procurement, maintenance, and operation costs. The need for larger equipment and complex systems directly translates into higher initial investment costs and long-term operation costs, reducing the economic benefits of the cylindrical battery recycling and repair project. Summary of the Invention

Two pulling blocks 133 are hinged to the sides of the two first slide plates 132 close to each other. The two pulling blocks 133 on the same first slide plate 132 are in a state of spreading outwards. Rubber layers are provided on the sides of the two pulling blocks 133 on the same first slide plate 132 close to each other. The friction force can be increased through the rubber layers to ensure that the pulling blocks 133 can smoothly tear off the cut diaphragm. There are notches (not marked in the figure, which can be seen in Figure 7 ), and the pulling blocks 133 enter the material guide pipe 3 through these notches. A spring piece 134 is connected between the pulling blocks 133 and the first slide plates 132.

There is a receiving opening (not marked in the figure, which can be seen in Figure 9 ), and the pushing shaft 1313 is located in this receiving opening. Therefore, when the pushing shaft 1313 moves to the left, it can push the sliding frame 1311 to move to the left, and when the pushing shaft 1313 moves to the right, it can push the sliding frame 1311 to move to the right.

[0038] In the initial state, the contact shaft 135 contacts the inclined surface near the material guiding pipe 3 inside the guiding groove 137, the pulling block 133 is in an open state, and the elastic piece 134 is in a deformed state; the staff neatly stacks the cylindrical batteries in the loading box 111, the cylindrical batteries will fall onto the pushing plate 114, then a roll of plastic film is placed in the storage box 6, the plastic film extends out through the outlet on the storage box 6, then the plastic film is bypassed around the guiding wheel 8 and passes through between the electric conveying rollers 9 on the left and right sides, the electric conveying rollers 9 convey the plastic film upwards, convey the plastic film to the upper part inside the installation pipe 7, put the expanding ball 10 into the plastic film, the expanding ball 10 expands the plastic film, then the staff controls the telescopic rod of the air cylinder 113 to extend, drives the pushing plate 114 and the pushing shaft 1313 to move leftward, the pushing plate 114 is separated from the contact with the cylindrical batteries, the cylindrical batteries fall onto the receiving plate 112 under the action of their own gravity, at the same time, the pushing shaft 1313 will contact the sliding frame 1311 and push the sliding frame 1311 to move leftward, the sliding frame 1311 drives the sliding shaft 1312 to move leftward, the sliding shaft 1312 slides in the inclined opening 1310, so that the two sliding plates II 139 move away from each other, the sliding plates II 139 drive the two sliding plates I 132 to move away from each other, the sliding plates I 132 drive the pulling blocks 133 on the front and rear sides to move away from each other, the contact shaft 135 slides on the inclined surface near the material guiding pipe 3 inside the guiding groove 137, under the action of the elastic piece 134, the pulling block 133 closes inwards, then the contact shaft 135 slides on the inclined surface inside the guiding groove 137 away from the material guiding pipe 3, the pulling block 133 opens outwards, the elastic piece 134 deforms, then the staff controls the telescopic rod of the air cylinder 113 to shorten, drives the pushing plate 114 and the pushing shaft 1313 to move rightward, the pushing plate 114 pushes the cylindrical batteries on the receiving plate 112 rightward, pushes the cylindrical batteries into the material guiding pipe 3, at this time, the pushing shaft 1313 is separated from the contact with the sliding frame 1311, the pushing shaft 1313 continues to move rightward, when the pushing shaft 1313 contacts the sliding frame 1311 again, the pushing shaft 1313 pushes the sliding frame 1311 to move rightward, the sliding frame 1311 drives the sliding shaft 1312 to move rightward, the sliding shaft 1312 slides in the inclined opening 1310, so that the two sliding plates II 139 move closer to each other, the sliding plates II 139 drive the pulling blocks 133 on the front and rear sides to move closer to each other, the contact shaft 135 slides on the inclined surface inside the guiding groove 137 away from the material guiding pipe 3, according to the above working principle, it can be known that the pulling block 133 will first close inwards and then open outwards, repeat the above operation, continue to send the cylindrical batteries into the material guiding pipe 3, when the cylindrical batteries contact the cutting knife 124, the cylindrical batteries will push the cutting knife 124, the first spring 123 is slightly compressed, the first spring 123 will provide a certain thrust to the cutting knife 124, so that the cutting knife 124 can cut the diaphragm on the cylindrical batteries, and at the same time, damage to the cylindrical batteries can be avoided, the skinned cylindrical batteries will move to the notch of the material guiding pipe 3, when the telescopic rod of the air cylinder 113 extends,It will drive the pusher plate 114 to move leftward. The pusher plate 114 does not push the cylindrical battery, and the cylindrical battery remains stationary inside the guide pipe 3. At the same time, the pull blocks 133 on the front and rear sides will move away from each other. The pull blocks 133 close inward and are in close contact with the cut diaphragm on the cylindrical battery, and the cut diaphragm is torn off by the frictional force provided by the rubber layer on the pull blocks 133 to peel the cylindrical battery. Subsequently, the pull blocks 133 open outward, and the torn diaphragm falls from the pull blocks 133. Then, the above operations are repeated, and the cylindrical battery is continuously fed into the guide pipe 3. The peeled cylindrical battery will fall into the vertical pipe 5 along the guide plate 4. The expanding ball 10 can block the peeled cylindrical battery, preventing the peeled cylindrical battery from continuing to move downward. The electric conveying roller 9 continues to convey the plastic film upward and slews the plastic film onto the peeled cylindrical battery to complete the skin replacement of the cylindrical battery.

The blade 142 can cut the plastic film, reducing manual operation and improving efficiency. The blade edge of the blade 142 is inclined. During the cutting process, the blade edge of the blade 142 will contact the bottom of the cylindrical battery, and the blade 142 will push the cylindrical battery to move upward a small distance to avoid damaging the cylindrical battery by the blade 142.

The cylindrical battery with the skin replaced pushes the stopper 154 to move to the right, and the stopper 154 drives the slide plate three 153 to move to the right, compressing the second spring 156. The compressed second spring 156 can provide a leftward thrust to the stopper 154, enabling the stopper 154 and the push block 152 to clamp the cylindrical battery with the skin replaced. At this time, the telescopic rod of the electric push rod 151 continues to extend, and the cylindrical battery with the skin replaced continues to move to the right, and the cylindrical battery with the skin replaced will move out of the vertical pipe 5, facilitating the staff to take it.
