Description

TECHNICAL FIELD

[0001] The utility model relates to the cigarette manufacturing field more particularly, relate to an improved ZB45 packer trademark paper propelling device with overload protection function. BACKGROUND

[0002] ZB45 packer is the completion hard box cigarette packet packing work, trademark paper propelling device component's effect is that trademark paper is sent to the trademark paper that trademark paper acceleration wheel of last work position sends and carries out longitudinal push, longitudinal push to next work position and carry out positioning, then trademark paper transverse push device will trademark paper transverse push to the below of 5th packer, by 5th wheel and related mechanism complete next trademark paper's packing work.

[0003] ZB45 hard box packer's packing speed is 400 packets per minute, in the high speed operation of equipment, every trademark paper must be accurately and correctly sent to the below of 5th packer, when trademark paper produces jam in the process of longitudinal push and positioning in longitudinal propelling device, must immediately stop to avoid trademark paper jamming too much and damaging equipment, there is a set of overload protection mechanism on this trademark paper longitudinal push device, when trademark paper conveying channel sends trademark paper and produces skew (this skew has many reasons to cause, for example trademark paper conveying channel has gum dirt, trademark paper auxiliary material reason bending deformation, conveying channel roller pair pressure adjustment is not proper, conveying channel roller pair wear or unexpected reason can produce skew), in the process of longitudinal propelling, cannot accurately push to the position and produce jam, when this time, the overload protection mechanism on longitudinal push mechanism will timely release, detector (7) does not detect longitudinal propelling device on the specified electrical phase, sends signal and makes equipment stop and shows " trademark paper jamming " stoppage fault on display screen, operating personnel will treat trademark paper jamming fault according to the fault of screen display, after processing, need manually reset longitudinal propelling device, then can continue to start equipment.

[0004] As Figure 5The original overload protection device is a spring sheet (51) which presses a steel ball (52) in the first positioning hole (54) of the pusher, the steel ball (52) is larger than the length of the first positioning hole (54), when the spring sheet (51) presses the steel ball (52), a part of the steel ball (52) exceeds the first positioning hole (54) and is in close contact with the second positioning hole (53), so that the position is fixed. When the pusher is blocked, the transmission shaft continues to rotate, and the pusher (12) is blocked, then the steel ball (52) will be separated from the hole of the pusher under the action of the pusher, so that the pusher (12) is not in the pusher, at this time the detector (7) cannot detect the pusher, but the detector (7) detects the pusher due to the blockage, so the detector (7) will send a stop signal to the equipment. When the spring sheet (51) is deformed, the spring sheet (51) will be deformed frequently after a long time of operation and frequent blockage, and will be broken after a long time, so that the pushing device is invalid and cannot complete the function of pushing the trademark paper, and a new spring sheet (51) needs to be replaced. In the frequent separation process, the second positioning hole (53) corresponding to the steel ball (52) on the pusher (12) is worn out, and the gap between the pusher (12) and the transmission shaft is increased when the second positioning hole (53) on the pusher (12) is worn out. The consequences are that the pusher (12) shakes too much, which causes the pusher detector (7) to misreport, and a new pusher part needs to be replaced after this situation occurs.

[0005] In summary, the original trademark paper longitudinal pusher overload protection device is prone to breakage, the pusher part is prone to wear, and the time required to replace the spring sheet and the pusher is long, which seriously affects the effective operation rate of the equipment and increases the consumption of spare parts costs.

[0102] In the utility model, through the use of the adjusting mechanism 6, when the elastic force of the pusher 1 is adjusted, the pusher 1 does not need to be disassembled, the spring 3 can be directly adjusted by unscrewing and screwing the first adjusting part 61 and the second adjusting part 62 in the stopped working state, the working time required for disassembly and assembly is reduced, the parts are not damaged in disassembly, and the use efficiency of the equipment is effectively improved.

[0103] In the utility model, the connection is fixed connection or detachable connection, wherein the fixed connection is welding connection or direct processing into integral molding structure, and the detachable connection is internal and external thread connection or clamping connection or plug-in structure connection.

[0104] Finally, it needs to be explained that the above-mentioned is only the preferred embodiment of the utility model, and is not other forms of the utility model. Any skilled person in the art can change or modify the above-mentioned disclosed technology content into equivalent embodiments with equivalent changes. However, any simple modification, equivalent change and modification made to the above-mentioned embodiments according to the technical essence of the utility model without departing from the technical scheme content of the utility model still belongs to the protection scope of the technical scheme of the utility model.
