Description

Technical Field

[0001] The utility model relates to a cover opening device, in particular to an automatic cover opening device for a tobacco turnover box. Background Art

[0002] At present, some manufacturers in the tobacco industry adopt a production model of supplying tobacco from other places. This production model requires the use of a large number of tobacco turnover boxes. The usage process is: opening the cover of the tobacco turnover box, packing the tobacco, and returning the cover of the tobacco turnover box.

[0003] The tobacco turnover box is 120cm long and 120cm wide, and is made of stainless steel with a weight of 50Kg. Before packing tobacco into boxes, the box needs to be opened. Currently, the opening work is done by four suction cups falling at the same time. The suction cups are tightly attached to the upper cover of the tobacco turnover box to generate suction, and the upper cover of the tobacco turnover box is opened and maintained at a certain height by the adsorption force.

[0004] However, this structure has two problems. First, due to the smoke and dust in the production workshop, the fine smoke and dust adhere to the tobacco turnover box. When the suction cup is opening the upper cover of the tobacco turnover box, there is a problem of insufficient suction force of the suction cup, so that the tobacco turnover box opening work fails. Second, after the opening work is completed, the suction cup loosens due to insufficient suction force due to power outages, pipeline leakage, suction cup wear and other reasons, and the upper cover falls off, affecting normal production and safety.

[0024] The lifting cylinder mounting plate 7 is perpendicular to the two beams 5. The lifting cylinder 6 is fixed to the middle position of the top surface of the lifting cylinder mounting plate 7 by a bolt assembly. The lifting cylinder 6 is used to push and pull the suction cup mounting plate 8 to change the height of the suction cup assembly 9. The suction cup assembly 9 is a commercially available component and can be purchased directly. The suction cup assembly 9 includes a rubber suction cup and a suction cup connecting pipe. The rubber suction cup is fixed at the lower end of the suction cup connecting pipe, and the two are internally connected. The upper end of the suction cup connecting pipe is connected to the air pipe, which is not shown in the figure. In this embodiment, four suction cup assemblies 9 are installed on each suction cup mounting plate 8.

[0027] Furthermore, a plurality of soot blowing nozzles 2 are fixedly arranged on one side of the suction cup mounting plate 8, and the air outlet end of the soot blowing nozzle 2 is arranged vertically. In this embodiment, the number of soot blowing nozzles 2 is three, and one soot blowing nozzle 2 is arranged between two adjacent suction cup assemblies 9, so that the smoke and dust on the top of the box cover can be effectively removed.

[0028] In some embodiments, the structures of the two box cover limiting devices are exactly the same. The two box cover limiting devices both include a push-pull cylinder 12, a connecting plate 13, a linear slide rail 14, a support rod 15 and a support rod mounting plate 16. Each box cover limiting device includes two linear slide rails 14. The two linear slide rails 14 are respectively fixed at the ends of the two cross beams 5. A slider 17 is slidably installed on each linear slide rail 14. The slider 17 is fixedly connected to the top surface of the connecting plate 13. The lower end of the connecting plate 13 is fixedly connected to the support rod mounting plate 16. A plurality of support rods 15 are fixedly arranged on the support rod mounting plate 16.

The lower end of the side plate of the connecting plate 13 is fixedly connected to the support rod mounting plate 16 by a bolt assembly. The support rod 15 plays the role of supporting the box cover. The end of the support rod 15 is processed with a chamfer.

[0030] In some embodiments, an automatic control module is also provided on the top frame 4, and the automatic control module includes a PLC programmable controller 11, a lifting cylinder telescopic solenoid valve 19, a push-pull cylinder telescopic solenoid valve 20, an exhaust solenoid valve 21, an air blowing solenoid valve 22 and a smoke box in place detection switch 23. The lifting cylinder telescopic solenoid valve 19, the push-pull cylinder telescopic solenoid valve 20, the exhaust solenoid valve 21, the air blowing solenoid valve 22 and the smoke box in place detection switch 23 are all electrically connected to the PLC programmable controller 11. In addition, the lifting cylinder telescopic solenoid valve 19 is connected to the air source and the lifting cylinder 6 respectively through an air pipe, the push-pull cylinder telescopic solenoid valve 20 is connected to the air source and the push-pull cylinder 12 respectively through an air pipe, the exhaust solenoid valve 21 is connected to the exhaust fan and the suction cup assembly 9 respectively through an air pipe, the exhaust fan is not shown in the prior art figure, and the blowing solenoid valve 22 is connected to the air source and the soot blowing nozzle 2 respectively through an air pipe. It should be noted that due to the large number of circuits and air paths, in order to ensure the clarity and simplicity of the view, the wires and air pipes are not shown in the figure.

[0031] The working principle of the utility model is as follows: when the cigarette box in place detection switch 23 detects that the tobacco turnover box is in place, it sends a signal to the PLC programmable controller 11. After receiving the signal, the PLC programmable controller 11 controls the lifting cylinder telescopic solenoid valve 19 to work. The lifting cylinder telescopic solenoid valve 19 makes the lifting cylinder 6 extend and all the suction cup assemblies 9 fall. At the same time, the PLC programmable controller 11 controls the blowing solenoid valve 22 to open, so that the soot blowing nozzle 2 continues to blow air. When the suction cup assembly 9 falls into place and contacts the top surface of the box cover, the PLC programmable controller 11 controls the blowing solenoid valve 22 to close. Close, control the vacuum solenoid valve 21 to open, all the suction cup assemblies 9 generate negative pressure and suck the box cover, and then the PLC programmable controller 11 controls the lifting cylinder telescopic solenoid valve 19 to switch the state, so that the lifting cylinder 6 shrinks and the box cover is lifted. When the box cover moves into place, the PLC programmable controller 11 controls the push-pull cylinder telescopic solenoid valve 20 to work, and the push-pull cylinder telescopic solenoid valve 20 extends the push-pull cylinder 12, and the two connecting plates 13 approach each other, so that the support rod 15 moves to the bottom of the box cover, so that even if the box cover falls, it will be supported by the support rod 15 and will not fall to the ground. When the tobacco turnover box is filled with tobacco, it moves to the bottom of the frame 1, and the PLC programmable controller 11 controls the push-pull cylinder telescopic solenoid valve 20 to switch states, so that the push-pull cylinder 12 shrinks, and the support rod 15 moves to the outside of the box cover area. The PLC programmable controller 11 controls the lifting cylinder telescopic solenoid valve 19 to switch states, so that the lifting cylinder 6 extends. After the lifting cylinder 6 descends into place, the box cover covers the tobacco turnover box. The PLC programmable controller 11 controls the exhaust solenoid valve 21 to close, and the suction cup assembly 9 loses its adsorption force. The PLC programmable controller 11 controls the lifting cylinder telescopic solenoid valve 19 to switch states, so that the lifting cylinder 6 shrinks, and all the suction cup assemblies 9 rise, and a working cycle is completed.

The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
