Adhesive tape deviation rectifying device without vertical roller

[0028] Example 1:

[0029] Such as figure 1 and figure 2 As shown, a tape correction device of a free roller, comprising a stent 1 disposed at the bottom of the tape bottom, and the bracket 1 is provided with a friction wheel 2 and a correction wheel 3, and the correction wheel 3 is arranged side by side along the width direction of the tape. There are two, and the axis is provided along the conveying direction of the tape; the friction wheel 2 is located at one end of the correction wheel 3 and is provided along the width direction of the tape; the two ends of the friction wheel 2 respectively correspond to the corresponding A taper gear group 4 and a clutch mechanism 5 are connected between the correction wheel 3; the bracket 1 is also provided with a lifting mechanism 6 for lifting the bracket 1, so that the friction wheel 2 and the correction wheel 3 can be The lift of the lift mechanism 6 is in contact with the tape.

[0030] The lifting mechanism 6 includes a base 63 and a firs

[0037] Example 2:

[0038] The main difference from Example 1 is that if Figure 3 ~ 5 As shown, the first hinge 61 is located on the side of the friction wheel 2, the second hinge 62 being a retractable pitch cylinder.

[0039]Thus, once the extension length of the pitch cylinder is consistent with the length of the first housing, it is possible to constitute a parallelogram structure in parallel, under the driving of the rising cylinder, to achieve the horizontal lift of the stent, let the friction wheel and the correction wheel and the tape The bottom contact. Once the correct correction is completed, the pitch cylinder can be contracted, allowing the bracket to rotate down the other end, so that the entanglement is detached from the tape, and the friction wheel is in contact with the tape. If the tape runs in the subsequent, it is necessary to adjust the tapestive tape to contact the tape to correct the tape, and the adjustment is faster.

[0040] Example 3:

[0041] The main difference between the present embodiment and the second embodiment and the second embodiment is that the protrusions of the surface of the synchronous strip 7 are arranged to be rotatable roller 71, and the rotation shaft of the roller 71 is set along the direction of operation of the synchronous belt, such as Image 6 As shown, the arrows on the right side of the synchronization belt indicates the two directions of the operation of the sync tape, that is, the width direction of the tape. At the time of correcting, the synchronous strip is taken along the width direction of the tape to correct the tape, and the roller on the synchronous belt is in contact with the tape, in the tape forward direction, because the roller can scroll, so that the rubber tape is more friction in this direction Small, facilitates the life of the tape and the synchronous belt. In the tape width direction, the roller moves in the axial direction (ie the tape width) directi
