Can prevent that single cigarette short of taking cigarette from detecting and the device for eliminating font lower shroud
Technical field
The utility model relates to a kind of tobacco package machinery parts, the parts in especially a kind of single cigarette short detection and the device for eliminating, and specifically a kind of single cigarette short of taking cigarette that can prevent detects and the device for eliminating font lower shroud.
Background technology
As everyone knows, single cigarette short detects and device for eliminating is one of equipment important in the cigarette-packaging machine, wherein props up the single cigarette that uses in the wrapping machine at GD type cigarette and props up that to detect device for eliminating the most representative.In this class wrapping machine; because the running velocity of cigarette pushing plate is very fast; and propping up the speed of whereabouts, fixes substantially cigarette; when cigarette props up through the outlet of the rejecting on the font lower shroud; cigarette props up the effect that is easy to be subjected to the inertia resistance that the cigarette pushing plate rapid movement are produced and produces one cigarette is propped up to rejecting the application force that Way out moves; although this application force is very little; but the cigarette that it is enough to cause to fall and break sometimes props up and departs from original path of motion; oblique entering is rejected in the outlet; though what enter is small-sized; but be enough to influence the continuation whereabouts that follow-up cigarette props up; and in case the stoppage in transit that this situation will cause entire equipment occurs; influence output, operating personal must manually be discharged fume by hard stop, makes it recover normal.This phenomenon often takes place in actual production, must be overcome to guarantee normally carrying out of production.
Summary of the invention
The purpose of this utility model is to detect and device for eliminating is subject to the friction drag influence and causes cigarette to prop up the problem that falls to causing shutdown near overlap joint influence rejecting mouthful at existing single cigarette short, designs a kind of cigarette that can effectively prevent and props up the single cigarette short detection and the device for eliminating font lower shroud of overlap joint.
The technical solution of the utility model is:
A kind of single cigarette short of taking cigarette that can prevent detects and the device for eliminating font lower shroud, comprise font lower shroud 1, font lower shroud 1 is provided with rejects outlet 2, it is characterized in that being provided with an anti-cigarette gas hole 3 of taking that communicates with it on the top of described rejecting outlet 2, this anti-cigarette gas hole 3 direction to the space 6 between the cigarette channel 5 under font lower shroud 1 and the detection device for eliminating of taking tilts.
Be provided with the anti-auxiliary gas hole 4 of cigarette of taking in the bottom of described rejecting outlet 2.
Be horizontal arrangement at the described anti-axis of taking the auxiliary gas hole 4 of cigarette.
The beneficial effects of the utility model:
The function of the online detection rejecting of wrapping machine list cigarette short that the utility model is perfect;
The pore that the utility model is rejected the exit by front baffle board is blown, and has prevented that the structure discountinuity of font lower shroud rejecting outlet from causing lower flue to take the cigarette obstruction;
The utility model detects by single cigarette short and the control system of device for eliminating is periodically blown to rejecting outlet, and gas flow and speed are set and adjusted;
Characteristics such as simple in structure, convenient, easy enforcement that the utility model also has.
The utility model actual proving effect that uses on GD type cigarette-packaging machine is obvious, can not produce and take the cigarette phenomenon, has guaranteed carrying out continuously of production, helps improving split run output.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1~4.
A kind of single cigarette short of taking cigarette that can prevent detects and the device for eliminating font lower shroud, comprise the font lower shroud 1 (as shown in Figure 1, 2, 3) that transparent organic glass is made, font lower shroud 1 is provided with rejects outlet 2, top in described rejecting outlet 2 is provided with an anti-cigarette gas hole 3 of taking that communicates with it, this anti-direction inclination (as Fig. 4) of taking cigarette gas hole 3 to the space 6 between the cigarette channel 5 under font lower shroud 1 and the detection device for eliminating.In order to guarantee to obtain the better anti-cigarette effect of taking, the utility model also is provided with the anti-auxiliary gas hole 4 of cigarette of taking in the bottom of rejecting outlet 2, and this anti-axis of taking the auxiliary gas hole 4 of cigarette is horizontal arrangement.
Fig. 4 is the application scheme drawing of the utility model on detection of GD type list cigarette short and device for eliminating.Among the figure, 7 will detect up-to-standard cigarette and prop up the cigarette pushing plate of sending into next procedure for being positioned at the device bottom, and whether 8 prop up up-to-standard expansion plate sensor for detecting cigarette, and 9 be to export relative rejecting valve with rejecting, and 10 is the bench board turnover panel that is installed in font lower shroud 1 outside.
The utility model does not relate to part and can adopt the applicant to be realized in the relevant patent of first to file, can adopt existing technology to be realized yet.
In addition to the implementation, the utility model can also have other embodiment, and all being equal to replaces to technical scheme that equivalent transformation forms and all drop in the protection domain that the utility model requires.
