Fig. 2 is the axonometric chart of sheet material conveying mechanism of the present utility model.
Detailed description of the invention
Referring to figs. 1 through Fig. 2, sheet material unlimited lengthening mechanism, including pressure splicing body and sheet material conveying mechanism, wherein pressure splicing body is made up of the drive mechanism of pressure lock 1 and pressure lock 1, and drive mechanism drives pressure lock 1 to apply pressure to the stitching portion of sheet material and engages;Sheet material conveying mechanism is by can the board clamp 2 of opening and closing and opening and closing drive mechanism form, and sheet material conveying mechanism is installed on slide rail 3, and under the driving of translation mechanism, translational motion is between pressure lock 1 and sheet material discharging opening.Sheet material after chamfer cutting processing is sequentially sent to this equipment, by pressure splicing body by adjacent sheet edge gluing under the pressure of pressure lock 1, ensure that flatness and the bonding strength of junction, after pressure splicing, board clamp 2 moves to stitching portion and clamps splicing position, translate the most again, so ensure that sheet material splices position stress in course of conveying less, thus prevent from splicing disengagement or the dislocation etc. at position.This equipment can be automatically performed pressure splicing, carries and the technique such as shearing, and automaticity is high, it is possible to the effective production efficiency that improves ensure that the split quality of sheet material simultaneously.
The conveying of sheet material typically can use conveyer belt etc., it is contemplated that sheet material can produce bending and fold etc., it is unfavorable for using conveyer belt, and be easily caused splicing position and disengage or dislocation, therefore need during transmission splicing position is fixed, the scheme that this utility model uses is that the mode using clip realizes, including the board clamp 2 being made up of the gripper-arm of a pair open and close movement, the gripper-arm of board clamp 2 is opened so that board clamp 2 can move and enter into the position of pressure splicing body, then the splicing position of sheet material can just be clamped when board clamp 2 closes, then sheet material is moved until the edge to be spliced of sheet material is moved in pressure splicing body by translation.Wherein gripper-arm is installed on support by rotating shaft 4 is rotating, and rotating shaft 4 is fixed with gear 5;What described opening and closing drive mechanism included being installed in two rotating shafts 4 two gears 5, two gears 5 engage each other, it is further fixed on cursor 6 in one rotating shaft 4, the end of cursor 6 connects the telescoping drive mechanism 7 driving cursor 6 to move up and down, wherein telescoping mechanism can be cylinder or hydraulic cylinder etc., telescoping mechanism drives cursor 6 to move up and down and drives the rotating shaft 4 generation rotation at corresponding cursor 6 place simultaneously, another rotating shaft 4 is driven to synchronize to produce rotation by meshed gears 5 transmission, along with the rotation of two rotating shafts 4, two gripper-arm produce the action opened or close the most accordingly.
In order to grip board material splice position, the quantity of described board clamp 2 is 4 groups, is respectively distributed 2 groups along sheet material both sides, is distributed and is installed on a support and corresponding gripper-arm is connected to same rotating shaft 4 before and after 2 groups of board clamps of the same side 2.Such 4 groups of board clamps 2 all can clamp before and after board material splice position, it is achieved fixing of splicing position, it is possible to effectively prevents from splicing disengagement or the dislocation at position.
Described pressure lock 1 is made up of upper lower platen, and upper lower platen connects upper and lower pneumatic cylinder respectively.The cylinder rod of pneumatic cylinder drives upper and lower presser motion to realize the folding of pressure lock 1.
For keeping board clamp 2 synchronous translational of both sides, the support of described sheet material both sides passes through synchronous connecting rod 8, and the top of support and bottom are separately installed with roller 9, coordinate with upper and lower slide rail 3 respectively.
Owing to spliced panel length is bigger, need sheet material base support during translation, for being also equipped with the supporting plate 10 for support sheet material between this described pressure lock 1 and sheet material discharging opening, the width of supporting plate 10 moves on the clamping download supporting plate 10 of board clamp 2 more than or equal to the width of sheet material, sheet material.Lower gripper-arm for the ease of board clamp 2 is opened, and described supporting plate 10 is provided with the hollow out position 11 that gripper-arm passes.
In order to make this equipment according to using needs or production standard that sheet material carries out cutting automatically, sheet material discharge outlet is additionally provided with the fixed size scissors 12 for shearing sheet material, and fixed size scissors 12 is made up of upper and lower shearing tool and fixed size scissors drive mechanism.
