Background technology
Packing chest, such as carton, base shape in the form of sheets after manufacturing is finished, they are conveyed into the packing chest shaping machine and are unpacked, and just can hold connection with wrapping of piece then.The case cog transferring device that kind of carton making machine was arranged in the past, it adopts an inclined-plane, realizes that by gravity landing case base the case base carries, and tends to the situation that causes the conveying box base not in place, makes shaping machine be difficult to accurately catch the case base, and what influence was unpacked normally carries out.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, feedway of carrying the packing chest base accurately put in place.For this reason, the utility model is by the following technical solutions: it comprises case base bracing frame, side shield, back shield, front apron, described front apron is a liftable, and described back shield can move front and back on throughput direction, and described feedway has the space that back shield seesaws.Because adopt technique scheme, the utility model is simple in structure, by cooperatively interacting of front and rear baffle, the case base presses together all the time, and is initiatively promoted by back shield one by one and export, carry accurately and also efficient high.
The specific embodiment
With reference to accompanying drawing.The utility model comprises case base bracing frame 1, side shield 2, back shield 3, front apron 4, they are installed on the board 100, described front apron is a liftable, and described back shield can move front and back on throughput direction, and described feedway has the space that back shield seesaws.
Described back shield is driven by chain 5, drawing reference numeral 52 indications are sprocket wheel, drawing reference numeral 51 indications are for driving the cylinder of sprocket wheel, cylinder 51 promotes sprocket shaft 53 and rotates, sprocket wheel and sprocket shaft are unidirectional drive connection, drive sprocket rotation when being the sprocket shaft forward rotation, when the sprocket shaft backward rotation, skid between sprocket shaft and the sprocket wheel.The lower end of back shield is provided with the pipe link (being blocked and not demonstration by case base bracing frame 1 among the figure) that can insert chain link, and when connecting back shield and chain, only need insert pipe link and get final product in the chain link, and operation is very easy for attended operation, dismounting.In the present embodiment, described case base bracing frame is long trough, and described chain is under the slotted eye 11.
The utility model also is provided with the guided way 6 of back shield and the slide block 7 on the guided way, and guided way 6 can be arranged on any position that is suitable for back shield 3 guiding on the board 100, such as the bottom or the side of back shield.In the present embodiment, described guided way 6 is arranged on the side of back shield 3, highly be higher than case base bracing frame, the opposite side of side shield is provided with described side shield 2, like this, this side that guided way is set can become the driving surface of the case base of packing into, and guided way can become the border that the case base is stacked, and helps the case base and is accurately exported.Described back shield is connected with slide block 7 by connecting cantilever 8.The bottom of described side shield is bent into case base stay bearing plate 21 to the back shield direction.
Described front apron 4 is driven by cylinder 9 and hole 101 liftings from the board, described cylinder is installed under the board, the top down, described front apron is formed by some and is connected on the pipe link 10, described top is connected with pipe link 10, front apron 4 blocks the case base when upper, when the next, be lower than the height of lower support frame.
When using the utility model, be in when upper, be erected on the case base bracing frame a plurality of case bases are stacked, rely on back shield 3, side shield 2 and front apron 4 that the case base is pressed together at front apron 4; During work, cylinder 9 actions make front apron 5 toward descending, cylinder 52 actions, make sprocket wheel 51 rotate forward impelling a slice case base, front apron rises once more and stops second case base, and makes first case base enter the inner shaping of unpacking of packing chest shaping machine by the corresponding mechanism of packing chest shaping machine.So circulation.
