Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-5, a shrinking and expanding device for an unreeling machine comprises a central rotating shaft 1 in transmission connection with an unreeling driving motor, wherein a shrinking and expanding base 2 is installed on the outer side of the central rotating shaft 1, and a mounting hole for inserting the central rotating shaft 1 is formed in the shrinking and expanding base 2. The shrinkage and expansion base 2 is provided with a plurality of shrinkage and expansion blocks 4 which are symmetrically arranged relative to the center of the shrinkage and expansion base through an inclined plane guide mechanism 3, and the two groups of shrinkage and expansion blocks 4 are symmetrically arranged in front and back relative to the shrinkage and expansion base 2. The outward sides of the expansion blocks 4 are respectively provided with an arc expansion plate 5 for directly attaching to a strip, a synchronous driving mechanism 6 is arranged between the expansion blocks 4 to keep the expansion blocks 4 synchronously slide to ensure that the radial moving distances of the expansion plates 5 are the same, and an axial positioning mechanism 7 is arranged between the expansion plates 5 and the expansion base 2 to limit the relative positions of the expansion plates 5 and the expansion base 2, so that the expansion plates 5 are prevented from axially shifting relative to the expansion base 2 in the adjusting process.
Specifically, similar to the existing inclined plane guide structure, the inclined plane guide mechanism 3 in this application includes the guide block 31 disposed outside the contracting and expanding base 2, and the guide block 31 corresponds to the contracting and expanding block 4 one by one and is symmetrical with respect to the contracting and expanding base 2 in the same way as the contracting and expanding block 4. A circumferential limiting component 32 is arranged between the guide block 31 and the shrinkage and expansion base 2 to ensure that the guide block 31 slides along the circumferential direction of the shrinkage and expansion base 2, an axial adjusting mechanism 33 is arranged between the guide block 31 and the shrinkage and expansion base 2 to provide driving torque for the guide block 31 and the shrinkage and expansion block 4, and an inclined surface guide component 34 is arranged between the guide block 31 and the shrinkage and expansion block 4 to convert the axial driving torque provided by the axial adjusting mechanism 33 into radial shrinkage and expansion torque.
As can be seen from FIG. 1, the guide block 31 is generally larger in volume than the expansion block 4, the inclined guide assembly 34 includes guide inclined surfaces 341 disposed outside the guide block 31 and inside the expansion block 4, and the inclined length of the guide inclined surfaces 341 of the guide block 31 is also generally larger than that of the expansion block 4, so as to ensure that the guide block 31 provides better support stability for the expansion block 4. Different from current guide structure, the relative base 2 middle part symmetrical arrangement that rises that contracts of guide block 31 in this application, the base 2 that rises that contracts respectively of guide block 31 and the base that rises that contracts divide into two sets of with the front and back of base 2 that rises that contracts respectively. The shrinkage and expansion blocks 4 are symmetrically arranged relative to the middle part of the shrinkage and expansion base 2 and are in one-to-one correspondence with the guide blocks 31. The expansion block 4 and the guide slope 341 of the guide block 31 are attached to each other, and a guide groove 342 and a guide bar 343 which are slidably connected are provided therebetween, and the cross sections of the guide groove 342 and the guide bar 343 are T-shaped or dovetail-shaped. When the expansion block 4 slides relative to the guide block 31, the guide bar 343 does not disengage from the guide groove 342.
Further, because each guide block 31 is relatively independent, in order to realize the sliding connection between the guide block 31 and the shrinkage and expansion base 2, a circumferential limiting component 32 is adopted to ensure the degree of freedom of axial sliding. The circumferential limiting component 32 comprises a circumferential limiting groove 321 which is arranged on the outer side of the shrinkage and expansion base 2 and extends along the axial direction, and the guide block 31 is provided with a circumferential limiting strip 322 which is connected with the circumferential limiting groove 321 in a sliding manner. The cross sections of the circumferential limiting groove 321 and the circumferential limiting strip 322 are also in anti-falling structures such as T-shaped or dovetail-shaped.
As can be seen from fig. 5, when the radial relative distance between the expansion and contraction plates 5 needs to be adjusted to meet the requirements of winding and unwinding strips with different radians, the axial adjusting mechanism 33 is activated under the action of the main control unit. The axial adjusting mechanism 33 includes an adjusting support ring 331 disposed in the middle of the expansion base 2 and located between the guide blocks 31 as a base point, adjusting screws 332 corresponding to the guide blocks 31 one by one are rotatably mounted on the adjusting support ring 331, threads on the adjusting screws 332 are symmetrically arranged relative to the adjusting support ring 331, adjusting holes 333 in threaded transmission with the adjusting screws 332 are formed in the guide blocks 31, and when the adjusting screws 332 rotate, the guide blocks 31 with two ends in threaded connection reversely and synchronously move along with the adjusting screws 332, and the moving distances are the same. An adjusting gear 334 is fixed in the middle of the adjusting screw 332 and the adjusting gear 334 is installed inside the adjusting support ring 331, an adjusting toothed ring 335 meshed with the adjusting gear 334 for transmission is rotatably installed on the adjusting support ring 331, and each adjusting gear 334 is driven by the adjusting toothed ring 335 to rotate synchronously. The adjusting ring gear 335 is in meshing transmission with an adjusting motor 337 via a planetary gear set 336. The adjusting motor 337 and the adjusting ring gear 335 are in variable transmission under the action of the planetary gear set 336, and are matched with a clutch structure to realize transmission ratio switching, so that the rotation direction of the adjusting screw 322 is adjusted.
In addition, since the contracting and expanding blocks 4 and the guide blocks 31 which are positioned in different radial directions in front and at the back of the contracting and expanding base 2 need to move synchronously, the synchronous driving mechanism 6 is adopted to transmit part of the axial driving torque received by the contracting and expanding blocks 4 into the other guide block 31. The synchronous driving mechanism 6 includes a driving pulling plate 61 disposed on one side of the adjusting support ring 331 and the driving pulling plate 61 is disposed outside the contracting and expanding base 2.

The positioning slide plate 73 has a positioning block 74 slidably connected to the positioning groove 72 to ensure that the expansion and contraction plate 5 moves radially relative to the expansion and contraction base 2.
It can be seen that in addition to addressing the winding requirements of a single width of strip, the retractor also needs to be flexible to accommodate strips of different widths. The shrinkage-expansion plate 5 comprises auxiliary plate bodies 51 which are arranged in pairs, a lock catch component 52 is arranged at the joint of the ends of the auxiliary plate bodies 51, and a translation component 53 is arranged between the auxiliary plate bodies 51 and the shrinkage-expansion block 4.

The electric push rod 521 can also independently extend and retract, so that the radial relative distance between the contraction and expansion plate 5 and the contraction and expansion base 2 is inconsistent, the strip wound by the contraction and expansion plate 5 is changed from a circle to an irregular shape, and the winding requirement of the flexible strip is met. A locking block 522 is fixed at the end of the electric push rod 521; the locking cavities 523 are respectively formed in the opposite ends of the auxiliary plate bodies 51 arranged in pairs, locking sheets 524 are rotatably mounted in the locking cavities 523, elastic reset pieces 525 are arranged between the locking sheets 524 and the locking cavities 523, locking ports 526 communicated with the locking cavities 523 are formed in the opposite sides of the auxiliary plate bodies 51, the electric push rod 521 and the locking blocks 522 of the auxiliary plate bodies, locking clamping grooves 527 opposite to the locking ports 526 are formed in the locking sheets 524, and locking buckles 528 at the end heads of the locking blocks 522 penetrate through the locking ports 526 to be inserted into the locking clamping grooves 527; a separation opening 531 communicated with the locking cavity 523 is formed in one side of the subplate body 51 opposite to the expansion block 4, a separation buckle 532 is arranged on the locking sheet 524, and a separation clamping groove 533 for the separation buckle 532 to penetrate through the separation opening 531 and be inserted with the separation buckle is formed in the expansion block 4.
