Description
Technical Field
[0001] The utility model relates to the technical field of tape conveying, in particular to an automatic winding device. Background Art
[0002] According to process requirements, during the processing of the tape, the tape needs to be die-cut and the die-cut tape needs to be wound. The existing winding device includes a winding shaft. Specifically, a paper core is first installed on the winding shaft, and then the end of the tape is fixed to the paper core. The winding shaft is driven to rotate by a driving mechanism, so that the tape is wound layer by layer at the same position of the paper core, thereby realizing the automatic winding of the tape. When using the existing winding device to wind the die-cut tape, since the tape becomes narrower after die-cutting, after winding, the narrow tape is wound at the same position of the paper core, and there is a certain waste at other positions of the paper core. The winding amount of a single paper core is small, and the paper core needs to be frequently replaced, which affects the winding efficiency.
[0003] Therefore, an automatic winding device that solves the above problems is needed. Summary of the Utility Model
[0004] The utility model provides an automatic winding device. The sliding frame drives the tape to move along the axial direction of the winding shaft, so that the tape is wound layer by layer and reciprocally around the winding shaft, thereby increasing the winding amount of a single paper core and avoiding the situation of low winding efficiency caused by frequent paper core replacement.
[0005] The technical solution of the utility model is realized as follows:
[0006] The automatic winding device includes a frame. A sliding frame driven by a power device is slidably installed on the frame along the axial direction of the winding shaft. A plurality of first guide wheels are rotatably installed on the sliding frame. A support arm is hinged on the sliding frame. The support arm includes a hinge plate hinged on the sliding frame. The hinge plate is hinged on the sliding frame through a hinge shaft. A fastener for locking the support arm is installed on the hinge shaft. A connecting rod is fixedly installed on the hinge plate. A guide assembly for guiding the tape is arranged at the free end of the connecting rod.
[0007] As a preferred technical solution, the guide assembly includes a mounting seat detachably installed at the free end of the connecting rod, and a second guide wheel is rotatably installed on the mounting seat.
[0008] As a preferred technical solution, the guiding assembly further includes a reversing wheel and a third guiding wheel rotatably mounted on the mounting base. The second guiding wheel is disposed above the third guiding wheel, and the reversing wheel is disposed between the second guiding wheel and the third guiding wheel. When the fastener is locked, the strip sequentially bypasses the first guiding wheel, the second guiding wheel, the reversing wheel and the third guiding wheel, and finally reciprocates and flatly winds around the winding shaft.
[0009] As a preferred technical solution, limiting ring grooves for limiting the strip are disposed on the outer peripheral surfaces of the first guiding wheel, the second guiding wheel, the reversing wheel and the third guiding wheel.
[0010] As a preferred technical solution, two limiting discs are mounted on the winding shaft, and a paper core is constrained and mounted between the two limiting discs.
[0011] As a preferred technical solution, the power device is a lead screw and nut drive mechanism.
[0012] As a preferred technical solution, the fastener is a locking nut.
[0013] As a preferred technical solution, the guiding assembly includes a guiding block detachably mounted on the free end of the connecting rod. A limiting groove for limiting the strip is disposed at the bottom of the guiding block. The extending direction of the limiting groove is perpendicular to the axis of the winding shaft. A reset element is disposed between the hinge plate and the sliding frame. When the fastener is loosened, the bottom of the lower end of the guiding block abuts against the outer peripheral surface of the winding shaft. The strip sequentially passes through the first guiding wheel and the limiting groove, and finally reciprocates and flatly winds around the winding shaft.
[0014] Adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0015] Since the automatic winding device includes a sliding frame, during the use of the device, the support arm is in a locked state. First, the paper core is mounted on the winding shaft, and then the end of the strip is fixed on the winding shaft. While the winding shaft rotates, the sliding frame drives the strip to move along the direction parallel to the axis of the winding shaft. The strip first winds parallelly around the outer peripheral surface of the paper core, and then as the sliding frame moves, the strip winds parallelly around the outer peripheral surface of the strip that has completed winding. In this way, reciprocatingly, the strip is wound layer by layer and flatly around the winding shaft. In the present utility model, by driving the strip to move along the direction parallel to the axis of the winding shaft through the sliding frame, the strip is wound layer by layer and flatly around the winding shaft. After winding, the sides of adjacent strips are abutted against each other, so that the wound strip is tightly arranged on the paper core, increasing the winding amount of the paper core and avoiding the influence on the winding efficiency due to frequent replacement of the paper core.
[0016] Since the automatic rewinding device includes a guiding assembly, and the guiding assembly includes a second guiding wheel, a reversing wheel and a third guiding wheel, during the process of the lead screw nut driving mechanism driving the sliding carriage to move, the limiting ring grooves on the first guiding wheel, the second guiding wheel, the reversing wheel and the third guiding wheel limit the strip before winding at multiple positions, so that the strip before winding moves with the movement of the sliding carriage, avoiding the occurrence of rewinding failure caused by the strip breaking away from the limiting groove. In the present utility model, the second guiding wheel, the reversing wheel and the third guiding wheel are arranged in an S shape, which can stably support and guide the strip, reduce the deviation or deviation of the strip from the predetermined path during the transmission process of the strip, and ensure the stable conveyance of the strip.
[0017] Since the automatic rewinding device includes a guiding assembly, and the guiding assembly includes a guiding block. During the use of the device, the support arm is in the unlocked state. First, lift the support arm, install the paper core on the rewinding shaft, lower the support arm, and under the action of the reset element, the bottom of the lower end of the guiding block abuts against the paper core. Fix the free end of the strip on the paper core and start rewinding. At this time, while the rewinding shaft rotates, the sliding carriage moves horizontally along the axis direction parallel to the rewinding shaft. The strip is first wound parallelly on the outer peripheral surface of the paper core, and then as the sliding carriage moves, the bottom of the lower end of the guiding block abuts against the outer peripheral surface of the strip that has completed winding. The tension spring is stretched, and the strip is then wound parallelly on the outer peripheral surface of the strip that has completed winding. This process is repeated, that is, the strip is wound layer by layer and reciprocally on the rewinding shaft. In the present utility model, under the action of the reset element, the guiding block is subjected to a pulling force approaching the rewinding shaft. As the number of layers of the strip on the rewinding shaft increases, the angle of the support arm is automatically adjusted, so that the guiding block abuts against the position to be wound, thereby realizing the layer-by-layer parallel winding of the strip on the rewinding shaft. Compared with the mounting seat, the guiding block has a small volume and does not need to avoid two limiting discs, thus reducing the installation distance between the sliding carriage and the rewinding shaft and making the device suitable for scenarios with limited installation space.

The support arm 5 includes a hinge plate 6 hinged to the sliding frame 3. The hinge plate 6 is hinged to the sliding frame 3 through a hinge shaft 7. A fastener for locking the support arm 5 is installed on the hinge shaft 7. A connecting rod 8 is fixedly installed on the hinge plate 6. A guide assembly for guiding the tape 9 is provided at the free end of the connecting rod 8.
[0027] Wherein, the guide assembly includes a mounting seat 10 detachably installed at the free end of the connecting rod 8. A second guide wheel 11 is rotatably installed on the mounting seat 10.
[0028] As Figure 3 shown, the guide assembly further includes a reversing wheel 12 and a third guide wheel 13 rotatably installed on the mounting seat 10. The second guide wheel 11 is disposed above the third guide wheel 13. The reversing wheel 12 is disposed between the second guide wheel 11 and the third guide wheel 13. When the fastener is locked, the tape 9 sequentially bypasses the first guide wheel 4, the second guide wheel 11, the reversing wheel 12, and the third guide wheel 13, and finally winds around the winding shaft 2 back and forth flatly.
[0029] In addition, limit ring grooves 14 for limiting the tape 9 are provided on the outer circumferential surfaces of the first guide wheel 4, the second guide wheel 11, the reversing wheel 12, and the third guide wheel 13.

A reset element is provided between the hinge plate 6 and the sliding frame 3. The reset element includes a tension spring 20. When the fastener is loosened, the bottom end of the guiding block 18 abuts against the outer peripheral surface of the take-up reel 2. The strip 9 passes through the first guiding wheel 4 and the limiting groove 19 in sequence, and finally winds around the take-up reel 2 in a reciprocating and flat manner.
[0035] In summary, the utility model drives the strip to move along the axial direction parallel to the take-up reel through the sliding frame, so that the strip winds around the take-up reel in a reciprocating and flat manner layer by layer, thereby increasing the winding amount of a single paper core and avoiding the occurrence of low winding efficiency caused by frequent paper core replacement.
