In this embodiment, the wrapping machine, when in use:
(1) Firstly, a stranded wire 1 passes through a through hole, then a wrapping belt 24 at a second top plate is connected and fixed with the wire 1, at the moment, because a feeding shaft 241 is positioned at the second top plate, the second top plate can extrude and shrink a second clamping rod 2432 into a second clamping groove 243, so that the feeding shaft 241 loses the limit of the second clamping rod 2432, the fixation between the feeding shaft 241 and a feeding hole is released, and meanwhile, a first clamping rod 234 is clamped with a limit limiting ring groove 242, so that the feeding shaft 241 is in rotary connection with the feeding hole, then a driving motor is started to drive a winding disc 23 to rotate, and meanwhile, the wire 1 moves at a set speed, so that the wrapping belt 24 is uniformly wound on the wire 1;
(2) When the wrapping tape 24 on the feeding shaft 241 is about to run out (namely, the winding disc 23 rotates for a set number of turns), the rotation of the winding disc 23 is stopped, the first telescopic rod 211 is started, the movement speed of the feeding plate 22 is consistent with that of the lead 1, the feeding plate 22 and the lead 1 are relatively static, at the moment, the third telescopic rod 232 is controlled, the clamping plate 233 which clamps the last wrapping tape 24 is driven to move towards the feeding shaft 241 which runs out soon, the two wrapping tapes 24 are bonded and fixed through adhesive by the extrusion between the extrusion plate 2332 and the feeding shaft 241, then the fourth telescopic rod 2331 is controlled, the extrusion plate 2332 is driven to recover, the end part of the wrapping tape 24 is released by the extrusion plate 2332, then the third telescopic rod 232 is controlled to shrink, the clamping plate 233 is driven to recover to the initial position (due to the design of the U-shaped bonding groove 2333, the clamping plate 233 is not driven to separate between the wrapping tapes 24 when moving backwards), and at the moment, the automatic replacement of the wrapping tape 24 is completed;
(3) Then, the second telescopic rod 2315 is controlled to drive the driving rack 2316 to move, and the feeding annular plate 231 is driven to rotate through the meshing transmission of the gears, so that the replaced last feeding shaft 241 moves to the second top plate, (because the driving gear 2314 is connected with the feeding annular plate 231 in a unidirectional rotation manner, when the driving rack 2316 moves backwards, the feeding annular plate 231 is not driven to rotate, and the overall stability is ensured); the second top plate is utilized to automatically release the rotation restriction on the feeding shaft 241, so that the feeding shaft 241 can rotate, and the winding belt 24 can be ensured to normally wind after being replaced; after the feeding ring plate 231 rotates by a set angle, the feeding shaft 241 with the new wrapping tape 24 moves to the clamping plate 233, the end part of the wrapping tape 24 can be accurately inserted between the clamping plates 233 due to the design of the supporting piece, and then the extruding plate 2332 is controlled to extrude and fix the wrapping tape 24 on the clamping plates 233 to wait for the next replacement;
(4) Then controlling the rotation speed of the winding disc 23 and the movement speed of the feeding plate 22, so that the feeding plate 22 and the winding disc 23 recover to the initial positions and the winding uniformity of the winding tape 24 is kept unchanged (namely, after the replacement of the winding tape 24 is completed, the movement of the feeding plate 22 is stopped, the winding disc 23 is driven to rotate according to the initial speed, then the feeding plate 22 is controlled to move backwards, and the winding uniformity of the winding tape 24 is kept unchanged by controlling the rotation speed of the winding disc 23 to be matched with the backward movement of the feeding plate 22;
(5) When the feeding shaft 241 separated around the wrapping belt 24 rotates to the first top plate, the first top plate can extrude the linkage rod 2344 to move, so that the first lock tongue is controlled to automatically shrink, the limit on the feeding shaft 241 is eliminated, and the feeding shaft 241 and the feeding hole can be automatically separated by adding the elasticity of the ejection spring 2433;
(6) The steps are repeated, so that the wrapping tape 24 can be automatically replaced sequentially, when the number of empty feeding holes reaches a set value (namely, when the number of empty feeding holes corresponds to the number of the feeding holes on the feeding plate 224), the first clamping rods 234 can be automatically contracted until the limit ring grooves 242 are met, the first clamping rods 234 can be inserted into the limit ring grooves 242, so that the feeding shafts 241 are fixedly connected with the feeding holes, and in the recycling process of the feeding plate 224, the feeding shafts 241 are only clamped and connected with the feeding shafts 241, so that the feeding shafts 241 can be automatically separated from the feeding holes, the new feeding shafts 241 with the wrapping tape 24 are automatically inserted into the feeding holes, and when the feeding shafts 241 are inserted into the feeding holes, the first clamping rods 234 are more accurately inserted into the limit ring grooves 24, and the second clamping rods 234 are prevented from being inserted into the ring grooves 24 simultaneously when the first clamping rods 241 are more accurately clamped with the end portions of the first clamping rods 234, and the second clamping rods 24 are prevented from being inserted into the ring grooves 24;
by the design, automatic winding, automatic replacement and automatic replenishment of the wrapping belt 24 are realized, so that the whole wrapping process is quick and efficient, and the whole production efficiency is effectively improved.
