Stacked packaging case lifting device

Abstract

The invention belongs to the field of packaging processing, and particularly relates to a stacked packaging case lifting device. The lifting device comprises a case lifting cross beam and a support, the device is characterized in that rotating wheels are arranged at the tops of the two ends of the case lifting cross beam, the lower sides of the two ends of the case lifting cross beam are respectively and fixedly provided with an oil cylinder upper seat, the inner sides close to the oil cylinder upper seat is further provided with a case lifting hanging plate respectively, the support is of anN-shaped structure, sliding rails are arranged on the inner sides of the left side support and the right side support, and the rotating wheels of the case lifting cross beam freely slide in the sliding rails. The device has the beneficial effects that the case lifting cross beam is movably connected with the rotating wheels of the support, so that the case lifting cross beam and the rotating wheels are not easy to damage, and the service life is prolonged; the two sides of the case lifting cross beam are respectively provided with the oil cylinder upper seat for installing an oil cylinder, thetwo ends of the lifting process are simultaneously stressed, and the lifting process is more stable and safer compared with a traditional single oil cylinder; the whole device is simple in structure,convenient to operate, low in overall cost and easy to popularize compared with a traditional device.

Description

technical field [0001] The invention belongs to the field of packaging processing, and in particular relates to a lifting device for stacked packing boxes. Background technique [0002] After the printed packing boxes are stacked, they need to be transferred and transported to the transport vehicle. The traditional lifting devices are all rigid contacts, without shock buffer devices, which may easily cause one end of the suitcase beam to appear due to the sudden lifting action of the stacked packing boxes. The phenomenon of high end and low end, accompanied by the phenomenon of "crawling", will lead to the deformation of the guide column in severe cases, which will aggravate the occurrence of asynchronous phenomenon, make the guide column wear quickly, shorten the service life of the guide column, and require high maintenance; Moreover, due to the difference in the flow rate between the oil cylinders and the manufacturing accuracy of the guide pillars and movable supports, t...

[0002] After the printed packing boxes are stacked, they need to be transferred and transported to the transport vehicle. The traditional lifting devices are all rigid contacts, without shock buffer devices, which may easily cause one end of the suitcase beam to appear due to the sudden lifting action of the stacked packing boxes. The phenomenon of high end and low end, accompanied by the phenomenon of "crawling", will lead to the deformation of the guide column in severe cases, which will aggravate the occurrence of asynchronous phenomenon, make the guide column wear quickly, shorten the service life of the guide column, and require high maintenance; Moreover, due to the difference in the flow rate between the oil cylinder and the oil cylinder and the manufacturing accuracy of the guide column and movable support, the problem of unbalanced crossbeam of the suitcase will also occur; the traditional lifting device also has the problems of complex structure, inconvenient operation, and high overall cost.
