Technical Field

The utility model relates to a bundling device, specifically speaking relate to a bundling device in sealing member plastic packaging area.

Background

In order to ensure the normal operation of bearings in large-scale mechanical equipment such as metallurgy and wind power, a sealing element with a larger diameter needs to be installed in the equipment, so as to prevent the leakage of internal lubricating oil and the invasion of external water vapor and impurities, the bearings are precise parts, and have high requirements on the performance and the appearance of the sealing element, and the requirements on the transportation, the packaging and the storage of the sealing element are also very strict, so that the sealing element cannot be directly exposed in a turnover box or a warehouse, and the sealing element is required to be wrapped and protected by plastics, packaging paper and the like before being put into or out of a factory. The packaging method commonly adopted in the method is as follows: the plastic band with a certain width is wound around the sealing ring in an overlapping way by hand until the whole sealing ring is wrapped. Most of the packaging tapes purchased from packaging tape factories are large rolls having a diameter of 300mm or more, and in order to facilitate manual winding of the packaging seal, the large rolls need to be divided into a plurality of small rolls having a diameter of about 80 mm.

The structure of the coil separating device in the prior art mainly comprises a horizontal mounting bottom plate, a driven unwinding mechanism and a driving winding mechanism are respectively mounted on the left side and the right side of the mounting bottom plate, the driven unwinding mechanism is provided with a mounting support mounted on the mounting bottom plate, the mounting support is provided with a front vertical support plate and a rear vertical support plate, a fixing shaft is mounted between the tops of the front support plate and the rear support plate, and shaft sleeves are mounted at the two ends of the fixing shaft through bearings. When the plastic tape winding machine is used, a large package is wound on a shaft sleeve of the driven unwinding mechanism, the plastic tape on the large package is wound on a winding core of the driving winding mechanism for several circles, then the driving winding mechanism is driven, and the plastic tape can be continuously wound on the winding core of the driving winding mechanism until the plastic tape is wound into a small package with the diameter of about 80 mm.

The above-mentioned bundling device in the prior art has the main problem in the use: firstly, when the bundling is accomplished, because the driven unwinding mechanism of inertia effect can not in time stop, big book still is in the state of unreeling, secondly unreels the in-process at driven mechanism, and big book has influenced the holistic stability of driven mechanism in the phenomenon of skew before can appearing, back sometimes.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a when the bundling is accomplished, driven unwinding mechanism can in time stop thereby can not lead to the bundling device of the too much extra sealing member plastic packaging area of unreeling.

In order to solve the technical problem, the utility model relates to a bundling device of sealing member plastic packaging area, including horizontally mounting plate, driven unwinding mechanism and initiative winding mechanism are equipped with respectively to mounting plate's left and right both sides, driven unwinding mechanism have adorn in mounting bracket on the mounting plate, mounting bracket have before vertical, back backup pad, are equipped with the fixed axle between the top of preceding, back backup pad, and the axle sleeve is equipped with through the bearing at the both ends of fixed axle, follows the damping mechanism who is used for increasing relative rotation damping force between axle sleeve and the fixed axle is equipped with to circumferencial direction interval, the equipartition of axle sleeve.

As the improvement of the utility model, damping mechanism including seting up the mounting hole on the axle sleeve, the mounting hole is equipped with jackscrew, spring and damping piece according to the preface from outer to interior, the damping piece supports under the spring action of spring and leans on the fixed axle on.

The damping block is preferably a nylon block.

As a further improvement, the fixed shaft positioned outside the bearings at the two ends is provided with a circular limit baffle plate which is locked and positioned by the locking nut.

As a further improvement, the top of the front and rear supporting plates are respectively formed with a square groove, correspondingly, the cross-section of the two ends of the fixing shaft is square, and the two ends of the fixing shaft are overlapped in the square grooves at the top of the front and rear supporting plates.

The utility model has the beneficial technical effects that: after damping mechanisms for increasing the relative rotation damping force between the shaft sleeve and the fixed shaft are uniformly distributed at intervals along the circumferential direction of the shaft sleeve, when the coil is separated, the damping action of the damping mechanisms is resisted, the friction force between the shaft sleeve and the fixed shaft is increased, the shaft sleeve can stop rotating in time, the large coil also stops rotating correspondingly, and the phenomenon of excessive coil unwinding can be prevented; after the round limiting baffle which is locked and positioned through the locking nut is further arranged on the fixing shaft positioned on the outer sides of the bearings at the two ends, the phenomenon that the large coil is deviated in the front and back directions in the unreeling process can be prevented, and the stability of the driven unreeling mechanism can be improved.
