TECHNICAL FIELD
[0001] The utility model belongs to aluminum foil winding technical field, especially a detachable battery foil pipe core for pipe core. BACKGROUND
[0002] In the production process of battery foil, the pipe core needs to pass through the upper and lower air expansion shafts of the equipment first, and then the air is punched and the air expansion shaft is supported to ensure that the air expansion shaft and the pipe core can rotate synchronously after being fixed. Then the cut battery aluminum foil head is wound on the outer wall of the pipe core, and is fixed by adhesive tape or other medium. When the machine is started, the aluminum foil will continue to be wound on the pipe core. After the production reaches the required length of the customer, the machine is stopped, the roll is unloaded, and the roll is lifted away and packaged.
[0003] When producing some customer orders, because the length of the pipe core used by the customer's processing equipment is fixed, and the aluminum foil winding is required to be centered in the middle of the pipe core. For example, when the width of the aluminum foil product is 200-1300mm, the length of the pipe core is required to be 1450mm. When producing some double-width products, there is no way to center the aluminum foil roll in the middle of the pipe core. At present, when this situation occurs, the aluminum foil roll can only be produced without centering first, and then the wound aluminum foil roll without centering is rewound again to center the aluminum foil roll without centering. This method seriously affects the production efficiency, wastes electric energy, and greatly increases the cost. UTILITY MODEL CONTENTS

[0046] As shown in Figure 3 , one of the situations where the aluminum foil 6 and the winding drum assembly 1 are not centered during winding is shown. In the figure, L1 is the center line of the winding drum assembly 1, and L2 is the center line of the aluminum foil 6 roll. In this case, after the aluminum foil 6 is wound, the aluminum foil 6 and the winding drum assembly 1 are unloaded from the air shaft 5, and then the sixth pipe ring 1f and the seventh pipe ring 1g on the left are disassembled. By installing the sixth pipe ring 1f and the seventh pipe ring 1g on the fifth pipe ring 1e on the right, the aluminum foil 6 roll and the winding drum assembly 1 can be centered (as shown in Figure 2 ).
[0047] As shown in Figure 4 , another situation where the aluminum foil 6 and the winding drum assembly 1 are not centered during winding is shown. In the figure, L1 is the center line of the winding drum assembly 1, and L2 is the center line of the aluminum foil 6 roll. In this case, after the aluminum foil 6 is wound, the aluminum foil 6 and the winding drum assembly 1 are unloaded from the air shaft 5, and then the first pipe ring 1a on the right is disassembled. By installing the first pipe ring 1a on the second pipe ring 1b on the left, the aluminum foil 6 roll and the winding drum assembly 1 can be centered (as shown in Figure 2 ).
[0048] In actual situation, when the produced product exists the requirement of which a roll is not centered, the detachable ABS tube core connected by various ABS tube rings (according to the core requirement of customer order, the combination of various different length tube rings can ensure that the aluminum foil 6 is centered within the required range of customer after disassembly and reconnection, generally required 0-10mm) is used to normally produce according to the not centered state.
[0049] After the roll is disassembled, the tool is used to disassemble the ABS tube ring of the longer end and connect to the ABS tube ring of the shorter end, so that the previously not centered roll is centered by moving the tube ring, so that the reverse roll operation is not required, the production efficiency is improved and the cost of repeated production is reduced.
[0050] Embodiment 2
[0051] As shown in Figure 5 , Figure 6 , the two ends of the tube ring are respectively provided with a limiting cylinder 13 and a limiting groove 12, and the inside of the tube ring has a center hole 11, and the limiting cylinder 13 of one of the tube rings can be matched and arranged in the limiting groove 12 of the other tube ring.

The circumference of the limiting ring 14 is provided with a plurality of connecting holes, and the bolt assembly 4 is arranged on the elastic washer 3 and the limiting rings 14 on both sides of the elastic washer 3. In this way, in the case of too thin pipe rings, the limiting ring 14 and the bolt assembly 4 can realize the detachable connection of the two pipe rings, and the bolt assembly 4 limits the elastic washer 3. At this time, the existence of the elastic washer 3 can realize the function of contact connection with the gas expansion shaft 5, and can also contact the limiting rings 14 on both sides, ensuring the strength and coaxiality of the connection of the two pipe rings.
[0058] As Figure 12 shown, as a third preferred way, the limiting cylinder 13 and the limiting groove 12 are only matched and inserted. At this time, the limiting rings 14 of the two pipe rings play the role of limiting the elastic washer 3. Threaded holes are provided on the limiting cylinder 13 and the limiting groove 12, and the screw assembly 2 is arranged in the threaded holes, so as to realize the connection of the two pipe rings. On this basis, the length of the screw assembly 2 can be long enough to extend into the pipe ring, so that the screw assembly 2 tightly presses the elastic washer 3, which is used to adjust the connection of the elastic washer 3 and the gas expansion shaft 5.
[0059] Example 4
[0060] As Figure 13 , 14As shown, in this case, the limiting cylinder 13 and the limiting groove 12 are only matched and inserted. The inner walls of the two ends of the pipe ring are respectively provided with limiting rings 14, the limiting rings 14 are arranged between the limiting cylinder 13 and the limiting groove 12; and the elastic gaskets 3 are arranged between the two limiting rings 14 of each cylinder. In this case, the elastic gaskets 3 are arranged in the single pipe ring, instead of being arranged between the two pipe rings. The circumference of the limiting ring 14 is provided with a plurality of connecting holes, and the two limiting rings 14 at the connection of the two pipe rings are tightly attached to each other and provided with bolt assemblies 4. In this way, the disassembly and assembly of the two pipe rings can be realized through the bolt assemblies 4 and the limiting rings 14, and the elastic gaskets 3 arranged in the pipe ring are in contact with the gas expansion shaft 5, so that the connection and fixation of the winding drum assembly 1 and the gas expansion shaft 5 are realized.
[0061] The preferred embodiments of the utility model are merely used for limiting the utility model, for those skilled in the art, the utility model can have various changes and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
