Abstract
The utility model relates to a paper cutter with a double guide and double push paper pushing bar. A screw pair composed of a screw mandrel and nuts is arranged in a longitudinal midline plane of symmetry under a workbench. One end of the screw mandrel (6) is connected with an electromagnetic brake. Right and left sides of the workbench are provided with side guide plates (12). The utility model is characterized in that the right and left sides of the screw mandrel are respectively provided with a guide lever (11) which is fixed in front and back and paralleled with the screw mandrel, and a feed screw nut and a guide sleeve (10) on the guide lever are connected into integration through feeding a leading bogie (13) which is connected with the paper pushing bar through a side push pedal (8). The utility model can ensure a cutting size and especially the precision of small-sized printed matter.
Description
The utility model relates to the package printing machinery field, and particularly a kind of pushing adopts the paper cutter of two guide and two pushing structure.
Existing paper cutter pushing structure (see figure 1), be on work top (1), to open vertical guide groove (5), then guide pad (3) is packed in the guide groove, screw mandrel (6) and nut (7) constitute the screw mandrel screw pair, drive pushing (4) by its upper screw rod rotation, finish pushing away paper and resetting, be contained in cut-off knife on the frame (2) and carry out paper stock by the size of fixing and cut.This structure has following shortcoming: 1, because guide pad length is restricted, and pushing motion is steady inadequately, easily produce upwards and about string moving, influence pushes away the paper positioning accuracy; 2, screw mandrel screw pair and pushing direct connection when the pushing operation is not steady, cause screw mandrel elasticity to hand over shape, influence positioning accuracy, and easily cause the screw pair wearing and tearing, have strengthened and have pushed away the paper deviations; 3, drive gathering sill on the table top, groove width is greater than 40 millimeters, and the little printing that cigarette is sealed applique and so on loses relies on and flexural deformation cuts nonsizing; 4, the lubricant residue of guide groove often adheres on the work top, causes printing to pollute.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of pushing to adopt two two paper cutters that push away of leading, and it can guarantee to cut the particularly precision of small size printing of size.
The purpose of this utility model takes following measure to reach: a pushing is arranged on the work top of paper cutter, smooth slotless on the workbench longitudinal midline face, the screw pair that has screw mandrel and nut to constitute under the workbench in the longitudinal midline plane of symmetry, screw mandrel one end is associated with electromagnetic brake, at workbench the right and left the side mark plate is arranged, feature is: the front and back that each side have of screw mandrel are fixed and the guide post parallel with screw mandrel, fuse by the feeding leading truck between the fairlead on feed screw nut and the guide post, link to each other by the thruster plate between leading truck and the pushing.
Above-mentioned its top and the bottom of a pair of thruster plate that are positioned at the workbench both sides are respectively with pushing with the feeding leading truck is fastening links, and the thruster plate places the elongated slot between workbench and the side mark plate, 10 millimeters of elongated slot width e=thruster plate thickness.
The guide post axis is apart from distance h=120～180 of table top millimeter, preferably 150 millimeters; Apart from the workbench sideline apart from p=100～180 millimeter, preferably 120 millimeters.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is existing paper cutter pushing structural representation sketch.Fig. 2 is according to the pushing two guide and two pushing structure simplified schematic diagram (cross section and vertical view) that the utility model proposes.Fig. 3 is the transmission simplified schematic diagram (upward view) of pushing two guide and two pushing structure.
Shown in Fig. 2,3, the underneath type structure is adopted in the transmission of paper cutter pushing.Cut-off knife is housed, smooth slotless on the workbench longitudinal midline face on the frame (2) that links with workbench (1).Be positioned at the longitudinal midline plane of symmetry under the workbench screw pair that drive lead screw (6) and nut (7) constitute is housed, screw mandrel is a two-wire, and helical pitch is 20 millimeters, and bearing is equipped with at the screw mandrel two ends, and the screw mandrel diameter is 36～44 millimeters, preferably 40 millimeters; Length is that the nut (7) of l=80～150 millimeter is complementary with trapezoidal screw (6), and the screw mandrel rear end is joining electromagnetic brake (15) and power input pulley (not drawing among the figure), and power is imported thus.
Fastening accurate fairlead (10) in two ends and guide post (11) structure are equipped with in the screw mandrel screw pair left and right sides, guide post diameter d=45～65 millimeter, preferably 50 millimeters, distance h=120～180 of guide post axis destage face millimeter, preferably 150 millimeters; The guide post axis to the workbench sideline apart from p=100～180 millimeter, preferably 120 millimeters, be fitted in fairlead length L=150～250 millimeter on the guide post, be preferably 200 millimeters.
The bearing at above-mentioned helical screw and guide post two ends is all fixing on the working plate bottom surface, and three rod axis are parallel to each other and are parallel to table surface.
By feeding leading truck (13) guide pin bushing of the nut of screw mandrel screw pair and guide rod guide pin bushing structure is combined as a whole, the two ends of feeding leading truck connect with pushing (4) by a pair of thruster plate (8) that is positioned at the workbench both sides again, with fastening connection of bolt (9), can adjust pushing between thruster plate and pushing by bolt.When screw mandrel rotated, this leading truck was done the advance and retreat motion on two screw mandrels, by the pushing on the moving workbench of thruster strip, finished given action.
Thruster plate (8) places between workbench and the side mark plate (12), and thickness is 9～11 millimeters, preferably 10 millimeters.When guaranteeing motion the thruster plate not with other member generation grazing, go everywhere without any hindrance here, require little elongated slot width e=thruster plate thickness+0.5 that the thruster plate passes through millimeter on the structural design.
The utility model has following advantage compared to existing technology: 1, can guarantee to cut the precision of size, Can guarantee especially the precision of small size printing; Be equipped with the program control of Chinese patent 902231405 Technology, printing cut precision and have been stable at 0.15 millimeter; 2, do not pollute paper stock and printing; 3, Pushing and the fine setting of the blade depth of parallelism are more easy to operate; 4, the cancellation pushing is adjusted the rudder tail, the work director Though degree shortens 150～250 millimeters, improved on the contrary the stability of pushing motion; 5, push away The practicality simple for structure of paper a tree, used in making timber for boats, work top dust cover (14) is smooth generous.
