Description

Ribbon shaping and guiding mechanism of ribbon tool

Technical Field

The invention relates to a shaping and guiding mechanism, in particular to a ribbon shaping and guiding mechanism of a ribbon tool.

Background

Conventionally, the bulk self-locking plastic binding tapes are all manufactured by an injection molding process, the binding tapes are manually torn from an injection flow channel and then placed into a plastic packaging bag, the bulk binding tapes are seriously bent and deformed when being unpacked due to the fact that the binding tapes are in a slender shape and under the action of thermal stress and mechanical stress, the deformation has no great influence on the traditional manual perforation and binding, but when equipment is adopted for automatic binding, the bending and deforming binding tapes can seriously influence the automatic feeding and the final binding action; before 2016, for a handheld automatic binding tool, a mode of 'longitudinal forced prepressing' is generally adopted in the transverse feeding process of a binding tape, and a mode of 'transverse dredging' and forced shaping are carried out on the last binding tape; after 2016, the inventor of the present invention began to research the design and injection molding process of a ribbon, and guides related ribbon manufacturers in China to adopt the design of reducing the tail-raising angle of the ribbon, improve the injection molding production process and control the deformation, after the deformation of the ribbon is reduced, the feeding mechanism of a handheld automatic ribbon tool is also gradually evolved, and a plurality of shaping and guiding mechanisms which are adopted once are no longer adopted by the handheld automatic ribbon tool.

Disclosure of Invention

The invention aims to solve the technical problem that the conventional bulk plastic cable tie is deformed to cause insufficient reliability of automatic cable tie equipment or an automatic cable tie tool.

The invention provides a ribbon shaping and guiding mechanism of a ribbon tool, which adopts the scheme that: the frame of the automatic band-binding tool is provided with: the guide plate, the longitudinal pressing plate and the transverse guide rod are arranged on the guide plate; or also increasing: the torsion spring is used for longitudinally pre-pressing the belt body; or also increasing: and the tension spring is used for longitudinally pre-pressing the tail part of the binding belt.

Furthermore, the deflector is installed in the frame, it has guide way and ribbon head size cooperation to open on the deflector, the ribbon head is in transversely arrange in the guide way of deflector, and external power makes the ribbon head be in the guide way of deflector is interior along the length direction removal of guide way, and the ribbon head is in the guide way of deflector can not rotate, the deflector still holds the area body of ribbon.

Further, vertical clamp plate fixed mounting the deflector top, the bottom of vertical clamp plate front end is provided with inclined plane or cambered surface, perhaps vertical clamp plate adopts the sheet metal component preparation to set up the angle of a perk with the front end (being equal to and setting up the inclined plane bottom the front end), vertical clamp plate sets up and is close to last ribbon department (last ribbon, refer to that the ribbon that its area body aligns with the guide way of first direction claw and second direction claw), vertical clamp plate utilizes the inclined plane of front end bottom to push down lateral shifting's ribbon area body along longitudinal direction by force.

Furthermore, at least one side face of the front end of the longitudinal pressing plate is made into an inclined face or an arc face, when the binding belt is hooked and bound into a ring by the first guide claw, the binding belt is continuously tightened, when a belt body of the binding belt is contacted with the side face of the front end of the longitudinal pressing plate, the belt body of the binding belt slides along the inclined face or the arc-shaped side face of the front end of the longitudinal pressing plate by utilizing the flexible avoidance of the plastic binding belt due to the fixed fixation of the longitudinal pressing plate, and the automatic binding of the binding belt is completed; the mode that the band body slides along the inclined plane or the arc-shaped side surface of the front end of the longitudinal pressing plate by utilizing the flexible avoidance of the plastic band is called as a self-adaptive mode.

Further, or the longitudinal pressing plate is designed in a sliding mode, when the sliding longitudinal pressing plate is adopted, the side face of the front end of the longitudinal pressing plate does not need to be made into an inclined face or an arc face, when the binding tape is hooked and bound into a ring by the first guide claw, the binding tape is continuously tightened, and the longitudinal pressing plate slides so as to avoid interference with the binding tape body; the design of the longitudinal pressing plate adopting sliding needs to match the bundling speed of the binding tape and the sliding speed of the longitudinal pressing plate, and in order to avoid interference, the sliding longitudinal pressing plate needs to slide out of a working area before the body of the bundled and looped binding tape is contacted; and when the self-adaptive mode is adopted, the bound belt body is contacted with the side surface of the fixed longitudinal pressing plate, the fixed longitudinal pressing plate also plays a role in restraining the belt body, so the self-adaptive mode adopting the fixed longitudinal pressing plate has longer restraining time and restraining effect on the belt body, and the design of the sliding longitudinal pressing plate is not as simple, effective and reliable as the self-adaptive mode of the fixed longitudinal pressing plate.

Further, the horizontal guide bar that dredges sets up the band body of last ribbon and the gap department between the penultimate ribbon band body, horizontal guide bar be less than ribbon band body bottom when being in original condition so that let last ribbon pass through, before first direction claw work, horizontal guide bar that dredges can follow the band body of last ribbon and stretch out in the gap between the penultimate ribbon band body to last ribbon do horizontal plastic, dredge, direction, make the band body of last ribbon with the guide way alignment of first direction claw and second direction claw.

Further, the transverse sparse guide rod is arranged as follows: the straight line motion is parallel along the length direction of the binding belt; or the ribbon translates in the normal plane of the length direction of the ribbon; or in the normal plane of the length of the band.

Further, or increasing: the torsion spring is arranged on a protection plate above the binding belt and used for longitudinally and forcibly prepressing the middle part of the belt body of the binding belt which moves transversely; the torsion spring is replaced by either a common elastic steel wire or an elastic sheet metal part.

Further, or increasing: extension spring, extension spring sets up and is close to ribbon afterbody department on the guard plate that is located the ribbon top, extension spring forces the pre-compaction to lateral motion's ribbon area body afterbody, works as when first direction claw colludes, utilizes extension spring dodges in the ascending flexibility of radial direction the action of first direction claw reaches the effect of "self-adaptation" equally.

Further, perhaps design gliding round pin axle and replace extension spring realize vertical pre-compaction to the ribbon afterbody, likewise, need match good gliding round pin axle with the speed of colluding of first direction claw is in order to avoid colliding, in addition extension spring can utilize its self flexibility with the motion in first direction claw synchronous motion a period, promptly extension spring to ribbon afterbody restraint action time longer, more effective, consequently adopt gliding round pin axle not as extension spring's simple, effective, reliable design.

The invention has the beneficial effects that:

1. the technical scheme is simple and reliable, the two-way shaping is carried out on the ribbon, and the high requirement of the automatic bundling equipment on ribbon deformation control of the ribbon production process is lowered.

2. The technical scheme is simple and reliable, and the bundling reliability and compatibility of the automatic bundling equipment are improved.
