Background technology
Carton generally is folding sheet after manufacturing is finished, carton is shaped to be carton is strutted sequence of operations process for the three-dimensional shape that is suitable for the object vanning from the sheet rugosity, in packaging field, more and more employing mechanical devices carry out aforesaid operations at present.In this process, comprise suction box, push away case, mechanical actions such as upright case, folding lid, and so in mechanical device, be provided with the corresponding function assembly and transmission mechanism carries out above-mentioned action.At present, the driving of these transmission mechanisms is dispersed in the above-mentioned mechanical device, and therefore, has brought the structure problem of compactness, installation and inconvenient debugging inadequately.
Summary of the invention
The link gear that is used for the forming box moulding that technical problem to be solved in the utility model provides a kind of compact conformation, is convenient to install and debug.For this reason, the utility model is by the following technical solutions: it comprises main shaft, crank, first cam and second cam are housed on the described main shaft, and described crank, first cam and second cam optionally link to each other with the transmission mechanism of the transmission mechanism of the transmission mechanism that pushes away the box function assembly, suction box functional unit, upright box function assembly, the transmission mechanism that folding covers functional unit.Owing to adopt the technical solution of the utility model, the utility model adopts the main shaft Driven by Coaxial, has simplified suction box, pushes away case, the mechanical transmission structure of upright case, the action of folding lid, makes structure more compact and be convenient to install and debug.
The specific embodiment
With reference to accompanying drawing.The utility model comprises main shaft 1, crank 2, first cam 3 and second cam 4 are housed on the described main shaft, and described crank, first cam and second cam optionally link to each other with the transmission mechanism of the transmission mechanism of the transmission mechanism that pushes away the box function assembly, suction box functional unit, upright box function assembly, the transmission mechanism that folding covers functional unit.Main shaft 1 unify to drive the transmission mechanism that is connected with crank 2, first cam 3 and second cam 4 by driven by motor, pushes away box function assembly, suction box functional unit, founds the box function assembly, rolls over and cover functional unit and carry out the shaping work that packing case is finished in a series of action according to the order of sequence and make.
In concrete enforcement, can be according to the characteristics and the moulding process requirement of packing case, the transmission mechanism of the transmission mechanism that pushes away the box function assembly, the transmission mechanism of suction box functional unit, upright box function assembly, the transmission mechanism that folding covers functional unit are selected to distribute, and carry out corresponding the connection with crank 2, first cam 3 and second cam 4.
In the present embodiment, " described crank, first cam and second cam optionally link to each other with the transmission mechanism of the transmission mechanism of the transmission mechanism that pushes away the box function assembly, suction box functional unit, upright box function assembly, the transmission mechanism that folding covers functional unit " be:
The transmission mechanism of upright box function assembly links to each other with first cam, and the transmission mechanism that folding covers functional unit links to each other with second cam;
The transmission mechanism that pushes away the transmission mechanism of box function assembly and suction box functional unit is combined by the rocking bar 5 with two outputs 51,52 and is connected with described crank.
As shown in Figure 1, 2, 3, the transmission mechanism that pushes away the box function assembly also comprises the connecting rod 53 that is connected with output 51, and the transmission mechanism of suction box functional unit also comprises the connecting rod 54 that is connected with output 52; Rocking bar 5 is connected with crank 2 by connecting rod 55.Pushing away the box function assembly can be installed in and push away on the case track base 56 by connector is installed, and the suction box functional unit can be cylinder and sucker.
Shown in Fig. 1,2,4.The transmission mechanism of upright box function assembly comprises the cam rocker 61 that is connected with first cam, one end of cam rocker 61 is installed bearing and is connected with first cam, the other end of cam rocker 61 connects connecting rod, upright box function assembly can be sucker 63 and cylinder thereof, the transmission mechanism of upright box function assembly also can comprise fork 64, drawing reference numeral 65 is the rotating shaft of the fork 64 of connecting rod pulling, and drawing reference numeral 8 is a frame.
Shown in Fig. 1,2,5.The transmission mechanism that folding covers functional unit comprises the cam rocker 71 that is connected with second cam, one end of cam rocker 71 is installed bearing and is connected with second cam, the other end of cam rocker 71 connects connecting rod 72, upright box function assembly can be the functor 73 that can swing and connector is installed, drawing reference numeral 74 is the location fork of functor 73, the transmission mechanism of upright box function assembly also can comprise rocking bar 75, and drawing reference numeral 76 is the rotating shaft of rocking bar 75, and drawing reference numeral 8 is a frame.
The turning cylinder 9 of cam rocker 61 and cam rocker 71 is same rotating shaft.
