Utility model content
The deficiency that the utility model exists for prior art just, a kind of yardage control mechanism of trimmer is provided, can overcome paper in prior art in course of conveying, exist tension force inhomogeneous, there is the impact that the unfavorable factors such as power are pullled in move ahead inertia or hysteresis, thereby more accurately control sheet trimming length.
For addressing the above problem, technical solution adopted in the utility model is as follows:
A yardage control mechanism for trimmer, comprising:
Fixed length dispensing device, described fixed length dispensing device comprises material grasping axle, pressuring shaft one and material grasping motor, rolling of the face that rolls of described pressuring shaft one and described material grasping axle has interactional contact between face; Described material grasping motor is used for driving described material grasping axle to rotate; Described interactional contact refers to that described pressuring shaft one and the axle center of described material grasping axle have mutually close potential energy, thereby the paper rolling between face of the face that rolls to described pressuring shaft one and described material grasping axle has applied certain pressure;
Tension force holding device, described tension force holding device comprises feed spool, pressuring shaft two and feeding motor, and rolling between face of the face that rolls of described pressuring shaft two and described feed spool has interactional contact, and described feed spool is by described feeding driven by motor.
As the improvement of technique scheme, described fixed length dispensing device also comprises control module, and described material grasping motor is stepping motor or servomotor, material grasping motor described in described control module control.Material grasping motor and described parting tool described in control module control described here, be and be not limited to the restriction of the circuit connection structure to control module, material grasping motor and parting tool.Described control module makes to start described parting tool after the angular transposition of described material grasping driven by motor material grasping axle rotation definite value and carries out cutting operation.
As the improvement of technique scheme, described tension force holding device also comprises slide bar, tension axis, slide block, described slide bar is two and vertically arranges, and described slide block is two and is set with on two described slide bars, and the two ends of described tension axis are arranged on two described slide blocks.
As the improvement of technique scheme, described pressuring shaft one is arranged on connecting rod, and described connecting rod one end is hinged fixing, and the described connecting rod other end is handle, and described pressuring shaft one is between the two ends of connecting rod.The face that rolls of described pressuring shaft one is the face that the rolls mineralization pressure to described material grasping axle under Gravitative Loads, thereby firmly grasps paper.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The yardage control mechanism of a kind of trimmer described in the utility model, the angular transposition that adopts stepping motor or servomotor control material grasping axle to rotate, and prevent paper slippage by described pressuring shaft one, thereby make material grasping axle roll the displacement of the lines of face and the displacement of the lines amount of paper accurately equates; And by being set, further improves tension force holding device the constancy of the paper tension after unreeling, the moving velocity of paper is carried out to dual control simultaneously, the situation of avoiding its move ahead inertia or hysteresis to pull, thus sheet trimming length more accurately controlled.
Accompanying drawing explanation
Fig. 1 is the construction profile schematic diagram of the yardage control mechanism of a kind of trimmer described in the utility model;
Fig. 2 is the Facad structure schematic diagram of slide bar, tension axis and the slide block of the yardage control mechanism of a kind of trimmer described in the utility model.
The specific embodiment
Content of the present utility model is described below in conjunction with specific embodiments.
As shown in Figure 1, be the yardage control mechanism structural representation of a kind of trimmer described in the utility model.The yardage control mechanism of a kind of trimmer described in the utility model, comprise: fixed length dispensing device, described fixed length dispensing device comprises material grasping axle 1, pressuring shaft 1 and material grasping motor 3, and rolling of the face that rolls of described pressuring shaft 1 and described material grasping axle 1 has interactional contact between face; Described material grasping motor 3 is for driving described material grasping axle 1 to rotate; Tension force holding device, described tension force holding device comprises feed spool 4, pressuring shaft 25 and feeding motor 6, rolling between face of the face that rolls of described pressuring shaft 25 and described feed spool 4 has interactional contact, and described feed spool 4 is driven by described feeding motor 6.Material grasping axle 1 and feed spool 4 combineds action, make the tension force of paper controlled.
Further with improvement, described fixed length dispensing device also comprises control module 7, and described material grasping motor 3 is stepping motor or servomotor, and described control module 7 is controlled described material grasping motor 3.Again further with improvement, described tension force holding device also comprises slide bar 8, tension axis 9, slide block 10, described slide bar 8 is two and vertically arranges, and described slide block 10 is two and is set with on two described slide bars 8, and the two ends of described tension axis 9 are arranged on two described slide blocks 10.Described slide block 10 can slide at described slide bar 8 easy on and off, and described tension axis 9 loads on paper unsettled, makes paper keep constant tension force.
