Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a buffer mechanism of a rotary upper strapping machine. Background Art

[0002] The strap sticking machine is a device that sticks the strap to bottled water or packaged bottled water. The strap is a structure with adhesive on both ends. It is usually rolled into a roll and installed on the material rack. In actual use, the strap is pulled by the feeding mechanism to the taping mechanism for taping. After taping is completed, the led-out strip of strap will be loose, and a buffer mechanism is needed to tighten this part of the strap. Utility Model Content

[0003] In view of the shortcomings of the prior art, the main purpose of the utility model is to provide a buffer mechanism of a belt-lifting machine which can dynamically accommodate more belt-shaped lifting belts and can timely tighten the belt-shaped lifting belts.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a buffer mechanism of a rotary top-sticking lifting machine comprises a fixed base plate, a feeding patterned roller and a feeding smooth roller are arranged at the bottom of the fixed base plate, a lifting unit is arranged in the middle of the fixed base plate, and the lifting unit comprises a lifting plate that slides up and down with the fixed base plate through a slide rail slider, a gas spring that can drive the lifting plate to move up and down is arranged on the back of the fixed base plate, a counterweight block is arranged on the lifting plate, and a shock-absorbing block that can abut against the lifting plate is also arranged on the fixed base plate below the lifting plate, a plurality of patterned rollers are arranged on the lifting plate, and a plurality of smooth rollers are arranged on the upper part of the fixed base plate, the rubber surface of the strip lifting belt contacts the feeding patterned roller and the patterned roller, the smooth surface of the strip lifting belt contacts the feeding smooth roller and the smooth roller, and the strip lifting belt is wound between the smooth roller and the patterned roller in sequence and at intervals.

[0005] Preferably, a side photoelectric sensor capable of detecting the counterweight is provided on one side of the lifting plate on the fixed bottom plate.

[0006] Preferably, a lower photoelectric sensor capable of detecting the belt-shaped handle is arranged on the fixed bottom plate between the feeding patterned roller and the feeding smooth roller.

[0007] Compared with the prior art, the utility model has the following advantages: the strip-shaped lifting belt is wound between the smooth roller and the patterned roller in sequence and at intervals. After each tape application is completed, the led-out strip-shaped lifting belt will become loose. At this time, the distance between the patterned roller on the lifting plate and the smooth roller on the fixed bottom plate will be reduced. Under the gravity of the counterweight block, the lifting plate drives the patterned roller to descend. At this time, the distance between the patterned roller and the smooth roller will increase, so that more strip-shaped lifting belts are in the buffer mechanism, wherein the rubber surface of the strip-shaped lifting belt contacts the feeding patterned roller and the patterned roller, the smooth surface of the strip-shaped lifting belt contacts the smooth roller of the feeding smooth roller machine, and the surfaces of the feeding patterned roller and the patterned roller are provided with an anti-sticking Teflon coating.

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] like Figure 1 As shown, a buffer mechanism of a rotary top-laminating and lifting machine comprises a fixed base plate 1, a feeding patterned roller 2 and a feeding smooth roller 3 are arranged at the bottom of the fixed base plate 1, a lifting unit is arranged in the middle of the fixed base plate 1, the lifting unit comprises a lifting plate 5 which slides up and down with the fixed base plate 1 through a slide rail slider 4, a gas spring 10 which can drive the lifting plate 5 to move up and down is arranged on the back of the fixed base plate 1, a counterweight block 6 is arranged on the lifting plate 5, and a shock absorbing block 7 which can abut against the lifting plate 5 is also arranged on the fixed base plate 1 below the lifting plate 5, a plurality of patterned rollers 8 are arranged on the lifting plate 5, and a plurality of smooth rollers 9 are arranged on the upper part of the fixed base plate 1, the rubber surface of the strip lifting belt contacts the feeding patterned roller 2 and the patterned roller 8, the smooth surface of the strip lifting belt contacts the feeding smooth roller 3 and the smooth roller 9, and the strip lifting belt is wound between the smooth roller 9 and the patterned roller 8 in sequence.

[0014] The buffer mechanism of a rotary upper belt-sticking machine of the present scheme has the following working principle: the belt-shaped belt is wound between the smooth roller 9 and the patterned roller 8 in sequence. After each tape sticking is completed, the drawn belt-shaped belt will be loose. At this time, the distance between the patterned roller 8 on the lifting plate 5 and the smooth roller 9 on the fixed bottom plate 1 will be reduced. Under the gravity of the counterweight 6, the lifting plate 5 drives the patterned roller 8 to descend. At this time, the distance between the patterned roller 8 and the smooth roller 9 will increase, so that more belt-shaped belts are in the buffer mechanism, and more belt-shaped belts can be dynamically accommodated. The rubber surface of the belt-shaped belt contacts the feeding patterned roller 2 and the patterned roller 8, and the smooth surface of the belt-shaped belt contacts the feeding smooth roller 3 and the smooth roller 9. The surfaces of the feeding patterned roller 2 and the patterned roller 8 are provided with an anti-sticking Teflon coating. The function of the gas spring 10 is to further increase the descending speed of the lifting plate 5 and shorten the reaction time of the entire buffer mechanism. If a traditional spring is used, the disadvantage is that it is easy to fatigue and break after high-frequency movement, and the spring needs to be replaced frequently. Now a gas spring 10 is used, which has the advantage that the elastic force can be adjusted by the gas pressure, and it is durable and reliable with high frequency.

[0015] Preferably, a side photoelectric sensor 11 capable of detecting the counterweight 6 is provided on the fixed bottom plate on one side of the lifting plate 5. The side photoelectric sensor 11 is used to detect the position of the lifting plate 5.

[0016] Preferably, a lower photoelectric sensor 12 capable of detecting the belt-shaped handle is provided on the fixed bottom plate 1 between the feeding patterned roller 2 and the feeding smooth roller 3. The lower photoelectric sensor 12 is used to detect whether the belt-shaped handle is disconnected.

[0017] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
