Abstract
The present invention relates to a safety gate device for seamless braiding machine, and is characterized by that it adopts sliding opening and closing mechanism, and its appearance is made into the form of circular arc for matching with cylindrical body of said braiding machine, in order to ease the opening and closing operation, it adopts two door leaves mode, and utilizes flexible element to implement connection so as to attain the goal of coupling linkage. When the safety gate is opened, it need only to push any door leaf open along the arc machine body, and can also have another door leaf opened so that it has no need of operation by using both hands.
Description
The present invention relates to a kind of safety-door device, refer in particular to the safety-door device that is used for tubular knitting machine.
When tubular knitting machine is finished knitting program, woven cloth must be taken out, so tubular knitting machine must leave an opening braided fabric can be taken out via this opening.Tubular knitting machine is a machine that runs up again, for avoiding operator's false touch machine, needs to establish a safety door at this opening, and after the safety door pass was appropriate, machine can turn round.The safety door of existing tubular knitting machine adopts pivoting more, door knob outwards must be pulled out during unlatching, and its shortcoming is can take up room when this safety door is opened, and especially when tubular knitting machine quantity was numerous, occupation space was considerable.In addition, the pivoting safety door mainly is divided into two kinds of single fan formula and two-leaf types again, and wherein single fan formula takes up space when opening most, though and two-leaf type takes up room when opening lessly, also must occupy rotating space; In addition, two-leaf type needs two actions or to close two fan door complete openings, dislikes inconvenience in the operation slightly.
Fig. 1 is shown to be the pivoting safety door 1 of commonly using tubular knitting machine, and wherein safety door shell 11 is provided with an opening 14, and its purpose can be taken out braided fabric by this opening 14.Because tubular knitting machine rotating speed in the running is high, be protection operating personnel's safety, this opening need be provided with safety door, when machine run, is able to safety door this opening is closed, and avoids personnel to touch unexpectedly.Fig. 1 shows it is the state that this safety door 12 is opened, because door is to open to external rotation, its outstanding safety door shell 11 is a lot of, so quite take up space, safety door 12 was around the track of door-hinge 13 rotations when wherein arrow pointed out that it is closed.
Purpose of the present invention promptly improving in unnecessary space waste, promptly provides a kind of safety-door device that is used for tubular knitting machine, and it is unlikely when opening to take unnecessary space.
Further purpose of the present invention is to provide a kind of safety-door device easy to operate, quick and simple in structure.

Preferred embodiment shown in the present invention incites somebody to action in conjunction with the accompanying drawings is elaborated as follows:
The invention provides a kind of safety-door device of slidingtype, embodiment as shown in Figure 2.This safety-door device comprise mainly that circular arc first slide construction 2 that cooperates the tubular knitting machine cylindrical outer shape and second slide construction 3 formed the two-leaf type safety door, and utilize slide construction, can on the orbital plane of last arc-shaped slide rail 4 and arc lower slide rail 8, move.Utilize affecting of flexible member between this biplate safety door, available one hand pushes away (drawing) and appoints Yishanmen can affect other Yishanmen simultaneously, and its structural principle is shown in Fig. 3 to 6.
At first consult Fig. 3 and 4, this figure shows the vertical view of arc-shaped slide rail 4, and it illustrates the scheme of installation of first flexible member 6.One of this flexible member 6 end is fixed on first of first slide construction 2 and installs a little 21, the other end earlier in a clockwise direction along last arc-shaped slide rail 4 around, and walk around guide wheel 5 in a clockwise direction, again with counter-clockwise direction along last arc-shaped slide rail 4 around, be fixed on second of second slide construction 3 at last and install a little 31.
Consult Fig. 5 and Fig. 6 again, this figure shows the vertical view of arc lower slide rail 8, and it illustrates the scheme of installation of second flexible member 10.One end of this flexible member 10 is fixed on the 4th of second slide construction 3 and installs a little 33, the other end earlier with counter-clockwise direction along arc lower slide rail 8 around, and walk around guide wheel 9 with counter-clockwise direction, again in a clockwise direction along arc lower slide rail 8 around, be fixed on the 3rd of first slide construction 2 at last and install a little 23.
Consult Fig. 2, arc lower slide rail 8 is identical slide rails with last arc-shaped slide rail 4, and be arranged on arc-shaped slide rail 4 under, the two is linked to be a structure with several supports 7 with it.The profile of first and second slide construction 2,3 and installation site are complete symmetries, all be provided with carriage, with present embodiment, this carriage can adopt pulley 22,24,32,34, these pulleys to roll on the orbital plane of last and arc lower slide rail 4,8.
Upper and lower arc- shaped slide rail 4,8 preferablies are can the U-shaped steel crooked and be shaped.In the present embodiment, the notch of this U-shaped steel is outside, and so, after first, second flexible member 6,10 was installed, this flexible member can major part be hidden in this notch and unlikely exposing, and can reduce the thickness of first and second slide construction 2,3.
Fig. 3 and Fig. 5 show the state that safety door is opened, when desiring to close this safety door, can force in arbitrary sliding door (i.e. first slide construction 2 or second slide construction 3), this two film gate is via the traction of flexible member 6 or 10, all simultaneously slide in opposition and reach the purpose of closing.Suppose to force in first slide construction 2, make it to rotate in a clockwise direction, then first flexible member 6 is relaxed state and does not act on, second flexible member 10 then is tension, its pulling force can spur second slide construction 3 through guide wheel 9 makes it move with counter-clockwise direction, till safety door is closed.Another kind of situation is, force in second slide construction 2, make it to rotate with counter-clockwise direction, then second flexible member 10 does not act on because of being relaxed state, 6 of first flexible members are tension simultaneously, its pulling force can spur first slide construction 2 through guide wheel 5 and make it mobile in a clockwise direction, till safety door is closed.The similar general pulley of the effect of guide wheel 9 or guide wheel 5 wherein, the relative motion mode of itself and flexible member 6 or 10 is for roll mode but not sliding type.
Fig. 4 and Fig. 6 show the safety door closing state.When desiring to open this safety door, can force in arbitrary sliding door (i.e. first slide construction or second slide construction 2,3), this two film gate is via the traction of flexible member, all can slide in the opposite direction simultaneously and reaches the purpose of opening safety door.Its principle is similar during to the closed safe door, all is to utilize the effect of flexible member traction and reach.More than alleged flexible member can adopt chain or cable wire to make.
As shown in Figure 7, the safety door gear can install an electric transmissio mechanism additional in addition, drives first slide construction 2 or second slide construction 3 of safety door gear with motor 26.Can install a chain 25 on this first or second slide construction 2,3, engage with this chain 25 and drive this first or second slide construction 2,3 and the output shaft of motor 26 can install a gear 27.So, can replace manually operated mode, reach the purpose of automation switch safety door.
Structure of the present invention and feature after above-mentioned detailed description and illustration, will be more concrete, and this embodiment is the usefulness that only conduct illustrates the preferable mode of operation of the present invention, but not with limitation protection scope of the present invention.
