Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and the specific embodiment:
Fig. 1 is the structural representation of the utility model film feeding device;
Fig. 2 is the structural representation of clamp apparatus;
Fig. 3 is out the structural representation of clamp device, and clip process mainly is shown out;
Fig. 4 is out the structural representation of clamp device, and the spiral camber track mainly is shown.
In figure: 1-clamp apparatus, 101-upper clamp, 1011-train wheel bridge, the 1012-permanent seat, 1013-slide block, 1014-turning cylinder, the 1015-torsion spring, 102-lower clamp, 1021-connecting bore, the 2-chain, the 3-sprocket wheel, 4-opens clamp device, the 401-horizontal segment, the 402-bending section, 403-spiral camber track, 404-adapter plate.
The specific embodiment
By reference to the accompanying drawings, a kind of film feeding device comprises clamp apparatus 1, chain 2, sprocket wheel 3 and opens clamp device 4.Clamp apparatus 1 is fixed on chain 2, and chain 2 drives revolution by sprocket wheel 3.Open clamp device 4 and be arranged on into film mouth and film outlet port place, be provided with spiral camber track 403 on it, be used for opening clamp apparatus 1.
Clamp apparatus 1 comprises upper clamp 101 and lower clamp 102, upper clamp 101 comprises train wheel bridge 1011, permanent seat 1012, slide block 1013 and turning cylinder 1014, train wheel bridge 1011 is arranged on the bottom of slide block 1013, slide block 1013 is fixed on permanent seat 1012 by turning cylinder 1014, is socketed with torsion spring 1015 on turning cylinder 1014.Train wheel bridge 1011 forms the film jaws with lower clamp 102, and lower clamp 102 is captiveed joint with permanent seat 1012, offers connecting bore 1021 on lower clamp 102, for being connected of clamp apparatus 1 and chain 2.
Open clamp device 4 and comprise out folder body and adapter plate 404.Open the folder body whole similar L shaped, it comprises horizontal segment 401 and bending section 402, and its direction of extension that postpones in the inboard of opening the folder body is provided with spiral camber track 403.When slide block 1013 slided on spiral camber track 403, spiral camber track 403 can give the twisting resistance that one gradually changes, and this twisting resistance can make it along with turning cylinder 1014 rotations, moves thereby drive on train wheel bridge 1011, and the film jaws is opened gradually.When slide block moved to a certain position of spiral camber track, the film jaws was opened fully, and film enters the film jaws.Closed gradually under the screen resilience effect that torsion spring 1015 gathers with the rear film jaws, film is clamped.Open the folder body the cross section similar be with jaggy three-back-shaped.Adapter plate 404 is arranged on out a side of folder body, is used for opening the folder body and is fixed on the desired location place.
The below describes operation scheme of the present utility model:
As shown in Figure 1, opening clamp device vertically is placed on into film mouth place, slide along opening the spiral camber track 403 that arranges on clamp device 4 in the top of slide block 1013, spiral camber track 403 gives slide block 1013 twisting resistances, this power is rotated its moving axis 1014 that rotates, and then move on drive train wheel bridge 1011, the film jaws is opened gradually.Meanwhile, the torsion spring 1015 that is socketed on turning cylinder 1014 gathers screen resilience.When slide block 1013 slid into a certain position on spiral camber track 403, as shown in Figure 3, this position was positioned at the front end position of horizontal segment, and the film jaws is thoroughly opened, and film enters jaws.Break away from gradually spiral camber track 403 with rear slider 1013, the twisting resistance that while slide block 1013 is subject to out clamp device and provides reduces gradually, the screen resilience that this twisting resistance gathers less than the torsion spring 1015 that arranges on clamp apparatus in earlier stage, therefore slide block 1013 moving axis 1014 counter-rotatings that rotate gradually, and then drive train wheel bridge 1011 resets, make the film jaws that forms between train wheel bridge 1011 and lower clamp 102 closed gradually, and film is clamped.When slide block broke away from the spiral camber track fully, the film jaws was fully closed, and the clamp apparatus clamping film together along with chain moves along certain track, until film outlet port.
The film outlet port place opens the clamp device horizontal positioned, and it can be opened the film jaws of clamp apparatus again, opens the folder principle the same, and film leaves clamp apparatus and enters next production link, and the clamp apparatus circulating motion is completed the transportation work of film.In with the upper film course of conveying, this device can not pulled open by the actv. protective film, and the folder film is reliable.
The part of not addressing in aforesaid way is taked or is used for reference prior art and can realize.
Need to prove, under the instruction of this specification sheets, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection domains of this patent.
