The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The utility model comprises running part and platen part.
Fig. 1 is the structural representation of a kind of embodiment of the utility model paper pressing device running part.Running part can be divided into non-motion parts and motion parts again.Non-motion parts comprises horizontally disposed tooth bar 10, and the two ends of tooth bar 10 are separately fixed on two tooth bar supports 9, and two tooth bar support 9 secured in parallel are on wallboard.Tooth bar 10 is a rectangular shape, and the upper surface of tooth bar 10 is the groove structure, and other three of tooth bar 10 is smooth surface.Motion parts comprises motor 1, and motor 1 is fixed on the traversing carriage 19, and motor 1 is connected with gear wheel shaft 6 by connecting shaft cover 2, and gear wheel shaft 6 coaxial packages have gear 3, the upper surface groove interlock of gear 3 and horizontally disposed tooth bar 10; The horizonal base plate of traversing carriage 19 is provided with three groups of axle sleeves 8, on every group of axle sleeve 8 bearing 7 is installed, three plane contact of three groups of bearings 7 and tooth bar 10, gear 3 makes the degree of freedom of the vertical and horizontal both direction of motion parts be restricted with three groups of bearings 7 together, make motion parts can only along tooth bar 10 vertically, be the length direction horizontal motion, this registration device has just guaranteed that head and crooked situation can not appear planting in running part integral body in the platen process.Also be provided with a limit switch 18 on wallboard, be used to withdraw from platen when work, traversing carriage 19 escape to behind the certain position control to motor 1 outage.
Fig. 2 is the structural representation of a kind of embodiment of the utility model device platen part, the paper-pressing part branch comprises support 5, support 5 is bolted to connection with traversing carriage 19, parallel direction with tooth bar 10 on the support 5 is equipped with two struts 11, the equidistant pressure roller shaft 15 that is connected with in the top of two struts 11, pressure roller shaft 15 is provided with pressure roller cover 14, is provided with globe bearing 16 between pressure roller shaft 15 and the pressure roller cover 14, and the two ends of pressure roller cover 14 are provided with shaft end ring 13; On the strut 11 between pressure roller shaft 15 and the support 5, be disposed with stage clip 12 and stage clip base 20, on the stage clip base 20 of a strut 11, be provided with travel switch 17 towards pressure roller shaft 15 directions.Whole being fixed together with traversing carriage 19 of platen part wholely moved or left to the paper roll direction, finishes the platen of paper roll and the work of withdrawing from.
During the work of the utility model paper pressing device, in the platen process, as shown in Figure 3, motor 1 driven gear 3 forward rotation, gear 3 rotates on tooth bar 10, make traversing carriage 19 move along tooth bar 10, platen part whole with traversing carriage 19 towards paper roll direction parallel motion, when roller shell 15 contacts with paper roll, platen part integral body continues to move forward, paper roll overlaps 14 1 power to pressure roller, makes pressure roller shaft 15 overcome the elastic force of stage clip 12, remains the state of pushing down paper roll; Pressure roller shaft 15 continues compressing stage clip 12 after several seconds, and pressure roller shaft 15 is touched travel switch 17, and control system is to motor 1 outage, and platen part integral body stops to move forward
After platen finishes, pass to counter-current for motor 1, gear 3 backward rotation, the platen part is oppositely left towards the paper roll direction with traversing carriage 19, as shown in Figure 3, because F power is the elastic force of paper roll among the figure, leave with front compression spring 12 at pressure roller cover 14 and paper roll and to be subjected to the elastic force effect, can make pressure roller and paper roll remain the impaction state time-delay several seconds, so, only need that corresponding adjusting is carried out in the restraint position of travel switch 17 and get final product if want to adjust platen power.
The utility model device can be adjusted platen power easily as required, thereby guarantees rewinding effect preferably, has improved degree of automation, has improved work efficiency.
