Glue is ordered gear
Technical field:
The utility model belongs to printing machinery, relates to a kind of glue of binding books and periodicals and orders gear.
Background technology:
Development along with binding technique, the staple together ratio of periodical of glue wireless, that do not have nail increases rapidly, it is also increasing that glue is ordered the kind of gear, in any case but change, present employed glue is ordered gear and is included connecting gear, back milling machine structure, gumming mechanism, sealing skin mechanism and the extrusion forming mechanism that is provided with book clamp; Signature after the printing is clamped by book clamp, delivers to the back milling machine structure by connecting gear, mills back of the body hacking, then bookblock is carried out gluing, sticks strip of paper used for sealing again, finishes whole forwarding after the extrusion forming.The book clamp of this adhesive binder is that two parallel flat boards constitute, and two blocks of plates are through on the axle, and one one is moving clamping plate in order decide clamping plate, and moving clamping plate make it mobile on axle by drive unit and spring, finishes the clamping of bookblock or unclamps.The book clamp of this structure is owing to the existence of axle, and sending into of signature is affected, and bookblock must just can enter the book clamp from following climbing, advancing the book passage is restricted, in large paper edition or the more soft signature book clips more difficult to get access, bookblock produces folding easily in the action of folder book, influence bookbinding quality.
Summary of the invention:
The purpose of this utility model provides and a kind ofly is provided with big opening book clamp, effectively improves bookbinding quality glue and orders gear thereby make large paper edition or more soft signature enter book clamp easily.
The realization the technical solution of the utility model is, a kind of glue is ordered gear, comprises the connecting gear, back milling machine structure, gumming mechanism and the sealing skin mechanism that are provided with book clamp, it is characterized in that, described book clamp comprises decides clamping plate and moving clamping plate, moves an end of clamping plate and decide clamping plate hinged.
The utility model has the advantages that, adopt the hinged book clamp structure of vice formula, the jointed shaft of fixed, the moving clamping plate of book clamp is installed in the into top of book passage, like this from the part bookblock of coming in of gathering leaves of a book do not need climbing just directly level enter the book clamp, easily realize the bookbinding of large paper edition or more soft signature, effectively improve bookbinding quality, and can improve bookbinding speed.In addition, the book clamp after the interlock has ensured sufficient clamping force under the effect of extension spring, makes that to mill the back of the body more stable.
Description of drawings:
Fig. 1 is the structural representation of book clamp of the present utility model.
Number in the figure: 1 drive rod, 2 driving levers, 3 connecting rods, 4 moving clamping plate, 5 decide clamping plate, 6 extension springs, 7 extension spring seats, 8 projections.
The specific embodiment:
Referring to Fig. 1, describedly decide to be hinged with on the clamping plate 5 driving lever 2, driving lever 2 stretches out, constitutes drive rod 1 in the hinged place; The other end of the other end of driving lever 2 and moving clamping plate 4 is hinged with two ends of connecting rod 3 respectively; Driving lever 2, connecting rod 3, moving clamping plate 4 and decide the clamping plate 5 parallel quadric chain of back formation that is hinged; Decide clamping plate 5 and be provided with extension spring seat 7, be provided with extension spring 6 between extension spring seat 7 and the driving lever 2.Frame of the present utility model is provided with projection 8, and when book clamp moved to projection 8 positions, projection 8 arrived on the drive rod 1, and driving lever 2 is rotated, and book clamp opens, and when leaving projection 8, under the effect of extension spring 6, the book clamp closure clamps bookblock.
