Seal back receipts or other documents in duplicate formula is gathered leaves of a book, press fit device
Technical field
The utility model relates to seal back technical field, particularly a kind of the gathering leaves of a book of the multi-joint single continuous paper in back, press fit device of printing.
Background technology
In the prior art, as shown in Figure 2, be used to print the gathering leaves of a book of the multi-joint single continuous paper in back, press fit device can not well singly press together multi-joint, and through after the paper feed port of printer, because paper feed port and paper friction produce resistance, therefore can make multi-joint single pressing position section often occur and scatter, thereby cause throwing off between connection and the connection, influence the normal use of product at last.Therefore, design is a kind of can have practical significance with the device that tightly fit together and not scatter of cutting into slices.
Summary of the invention
The purpose of this utility model is to provide a kind of the gathering leaves of a book of the multi-joint single continuous paper in back, press fit device of printing, and this device can singly be gathered leaves of a book multi-joint, and can well it be fit together after the pressing, thereby has improved product quality.
The technical solution adopted in the utility model is: comprise the sprocket wheel of being located at the page orientation end, it is characterized in that: described sprocket periphery is provided with chain, form closed chain transmission, described chain place outward be fixed with the multi-joint single continuous paper of traction lead the paper pin, described sprocket wheel front side is provided with the paw mechanism that platen pawl and base are formed; Described paw mechanism and lead the paper pin in the middle of be provided with pressing board.
Distinguishing feature of the present utility model is to establish a pressing board at the paw device with in the middle of leading the paper pin, when the pressing of multi-joint single process forms section and passes through pressing board, to cut into slices and roll over certain angle backward, thereby section is tightly fit together, improve the stability that use the multi-joint back of singly gathering leaves of a book, promptly improved product quality.
In addition, this apparatus structure is simple, and it is convenient to install, regulate, overhaul, and result of use is good.
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Description of drawings
Fig. 1 is the organigram of the utility model embodiment.
Fig. 2 is the multi-joint press fit device schematic diagram of singly gathering leaves of a book of tradition.
In the accompanying drawing, 1. lead the paper pin, 2. continuous paper, 3. sprocket wheel, 4. chain, 5. pressing board, 6. base,
7. platen pawl.
The specific embodiment
As shown in Figure 1, seal of the present utility model back receipts or other documents in duplicate formula is gathered leaves of a book, press fit device, comprise be located at the page orientation end sprocket wheel 3., 4. described sprocket wheel 3. circumference is provided with chain, form closed chain transmission, described chain place outward be fixed with the multi-joint single continuous paper of traction lead the paper pin 1., the described paper pin front side of leading is provided with the paw mechanism that 6. 7. the platen pawl formed with base; Described paw mechanism and lead the paper pin in the middle of be provided with pressing board 5..
3. above-mentioned sprocket wheel is driven by variable-frequency stepless speed-regulating motor.Described paw mechanism is by outside transmission system and closed chain transmission run-in synchronism, makes the enough stable paper of leading of multi-joint monoenergetic, multi-joint single the pressure can be incorporated in the pressing position and form section a during described paw mechanical operation; Single form section and by pressing board 5. the time when multi-joint through pressing, because pressing board is 5. apart from paper 0.5mm, a rolls over the shape that certain angle also forms section b backward so 5. pressing board is easy to just will cut into slices, thereby section is tightly fit together, improve the stability that use the multi-joint back of singly gathering leaves of a book, promptly improved product quality.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
