Description

Unreeling mechanism, reel changing device and battery core winding equipment Technical Field The application relates to the technical field of battery processing equipment, in particular to an unreeling mechanism, a reel changing device and electric core winding equipment. Background The unreeling mechanism is a mechanism for unreeling a material tape downstream, and generally includes an unreeling shaft on which a material roll is sleeved to unreel the material tape downstream. In the related art, for unreeling continuity, a plurality of material rolls are sleeved on an unreeling shaft along the axial direction, and when one of the material rolls is unreeled, a new material roll is pushed to continue unreeling. Because the unwinding shaft is sleeved with a plurality of material rolls, the unwinding shaft needs to bear the weight of the plurality of material rolls, so that the unwinding shaft needs to bear larger radial force, the mechanical strength requirement on the unwinding shaft is high, the manufacturing cost of the unwinding shaft is increased, and the unwinding speed of the unwinding shaft can be influenced by the plurality of material rolls. Disclosure of utility model The application discloses an unreeling mechanism, a unreeling device and a battery core winding device, which can reduce the manufacturing cost of an unreeling shaft and improve the unreeling speed of the unreeling shaft. To achieve the above object, in a first aspect, the present application discloses an unreeling mechanism, comprising: an unwind assembly including an unwind spool rotatably disposed, the unwind spool including a roll segment, and The standby roll assembly comprises a feeding assembly and a sleeve, wherein the sleeve is sleeved on the unreeling shaft and is located on one side of the material roll section along the axial direction of the unreeling shaft. Because the sleeve is sleeved on the unreeling shaft and is positioned on one side of the material roll section along the axial direction of the unreeling shaft, when the unreeling shaft starts to rotate, the unreeling shaft only needs to drive the material roll sleeved on the unreeling shaft to rotate, and does not need to drive the material roll sleeved on the sleeve to rotate together, so colloquially, the unreeling shaft only needs to bear the weight of one material roll sleeved on the unreeling shaft, and the weight of the material roll sleeved on the sleeve is born by the sleeve. On the other hand, the unreeling speed of the unreeling shaft can be improved to a certain extent because the unreeling shaft has smaller bearing. Optionally, the sleeve is used for bearing the material roll, and the feeding assembly is used for driving the material roll to axially move along the unreeling shaft. Optionally, the feeding assembly includes: Drive assembly, and The pushing piece is connected to the driving assembly, and the driving assembly is used for driving the pushing piece to move along the axial direction of the unreeling shaft. Optionally, a cushion block is arranged on one side of the pushing piece, which faces the material roll section. Through set up the cushion in the one side of pushing away material orientation section of rolling up, like this, when pushing away the material through pushing away material and rolling up, the material is rolled up and will contact and can not directly contact with pushing away material with the cushion, this one side, the cushion can play the effect of protecting pushing away the material to can avoid pushing away the impaired condition emergence of material, when the cushion impaired direct change cushion can, can reduce maintenance cost, on the other hand, the cushion is flexible contact with the contact between the material is rolled up, thereby can avoid the condition emergence of scraping the material. Optionally, the pushing piece is sleeved on the sleeve. Through making pushing piece cover locate the sleeve, when pushing the material roll on the sleeve through pushing piece, pushing piece can form the contact with the one end whole circle of material roll, so, on the one hand, can make the area of contact between pushing piece and the material roll great, and then can avoid the local atress of material roll too big to appear the circumstances of deformation, on the other hand, can make the whole circle atress of material roll more balanced to can guarantee better that the material roll can be along the axial of unreeling spool steady, smooth by the promotion to the material roll section. Optionally, the pushing member is located on at least one side of the sleeve in a radial direction of the sleeve. Optionally, the backup roll assembly further includes: The clamping assembly comprises a first driving piece and a first abutting piece, wherein the first driving piece is arranged on the pushing piece, the first abutting piece is connected with the first driving piece, and the first driving piece is used for driving the fir
