A kind of net feeding mechanism that is used for net sewing machine

Technical field:

The utility model relates to a net production equipment, is that a kind of automatic net sewing machine is realized go here and there and sent automatically net to arrive behind row's spring to go here and there that next arranges the mechanism of the station of spring.

Background technology:

The bed net of traditional sping mattress is by the little biconial spring of the big middle diameter of a kind of two ends diameter, by an elongated assembling spring with two one group of two one group are buckled together of biconial bed net spring, detain a row again after buckling well a row, so just formed the bed net.Automatically net sewing machine has been realized automation, promptly manually spring is arranged the clamp of putting into the folder spring after, finish the overall process of string net automatically by machinery.But gone here and there the position that the bed net opposite side that send last row to make spring of not gone here and there will be in the string net behind the row, at this moment just can put into next and arrange spring.The utility model promptly is that a kind of net of realizing send the mechanism of net to next station automatically.

Summary of the invention:

The utility model purpose is to overcome the deficiencies in the prior art, provides a kind of simple in structure, is easy to regulate the net feeding mechanism that be used for net sewing machine synchronous with other mechanism.

For achieving the above object, the technical scheme that the utility model provides is: include guiding wheel seat, guide wheel shaft, directive wheel, bearing, first fork, net feeding frame, rotating shaft, rolling bearing units, second fork, cam follower, cam, line shaft, support, send net hand, oscillating bearing, pulling seat, guide rail, line shaft is connected on the support, its left end is connected with cam by key, and right-hand member is equipped with the gear that drives this rotation; One end of cam follower is fixedly installed on second fork, and the rotatable part of the other end extend in the groove of cam; Second fork is, and to be the center with the rotating shaft be satisfied with on support by two rolling bearing units are rotating; First fork is installed in the rotating shaft left end, and second fork all is to be connected with rotating shaft by key with first fork; Oscillating bearing is equipped with at two of the connecting rod of rotating shaft both sides respectively, and wherein a joint shaft is installed on the top of second fork, and another oscillating bearing is installed on the pulling seat, and pulling seat is fixed on the net feeding frame; Net feeding frame is installed on the frame: the middle part of net feeding frame both sides is equipped with guide rail, and the circular arc of this guide rail one side is to cooperate with the circular arc of the indent of directive wheel, and directive wheel is installed on the guiding wheel seat by bearing, guide wheel shaft and nut; Network hand feeding is installed in the front portion of net feeding frame.

By above technical scheme, the utility model has reached beneficial effect simple, that easily regulate rational in infrastructure.

Description of drawings:

Fig. 1 is a front view of the present utility model;

The left side view of Fig. 2 for cutting open from A-A among Fig. 1;

Fig. 3 is Fig. 1 vertical view.

The specific embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to Fig. 1, Fig. 2, Fig. 3, line shaft 12 is to be rotationally connected with axle on the bearing block on the support by bearing, and its left end is connected with cam 11 by key, and right-hand member is equipped with the gear that drives this rotation.The curved slot that one circumference is arranged on the left end cam 11.One end of cam follower 10 is fixedly installed on second fork 9 of " 7 " font, and the rotatable part of the other end extend in the groove of cam 11.Second fork 9 of " 7 " font is, and to be the center with rotating shaft 7 be satisfied with on support 13 by two rolling bearing units 8 are rotating.It all is to be connected with rotating shaft 7 by key with first fork 5 that rotating shaft 7 left ends have been installed one first fork, 5, the second forks 9.The gear of line shaft 12 right-hand members is by other mechanism's driven rotary in the machine at work, so cam 11 also rotates with line shaft 12, and cam follower 10 also forces 7 swings at certain angle scope intercycle around the shaft of second fork 9 along the rolling of the curved groove inboard of cam 11.Just can regulate second fork 9 with respect to other motion of mechanism time if adjust the gear on line shaft 12 right sides and the tooth matching angle of other mechanism.

Oscillating bearing 15 is equipped with at the two that is distributed in the connecting rod 6 of rotating shaft 7 both sides as Fig. 1, Fig. 3 respectively.Wherein a joint shaft is installed on the top of second fork 9 by bolt, and another oscillating bearing also is installed on (as Fig. 3) on the pulling seat 17 by bolt, and pulling seat 17 is screwed on net feeding frame 6.The middle part of net feeding frame both sides is equipped with a guide rail 18 (as Fig. 1, shown in Figure 3).The circular arc of this guide rail one side is to cooperate with the circular arc of the indent of directive wheel 3.Directive wheel 3 is installed on the guiding wheel seat 1 by bearing 4, guide wheel shaft 2 and nut.A guiding wheel seat 1 and two directive wheels have been installed respectively in net feeding frame 6 both sides.The guiding wheel seat is to be fixed with screw to be installed on the support 13, and makes the directive wheel that is installed in compress the guide rail 18 of both sides on the net feeding frame 6.Net feeding frame 6 just can slide front and back in the groove of directive wheel like this.Foregoing pulling seat 17 is fixedly installed in net feeding frame 6 both sides, and the connecting rod two ends are connecting first fork 5, second fork 9 and net feeding frame 6 by oscillating bearing respectively.So also spurring the front and back of net feeding frame 6 when cam 11 forces 7 swings around the shaft of first fork 5, second fork 9 has simultaneously slided.The front portion of net feeding frame 6 is equipped with a network hand feeding 14, and this send the net hand between per two bed net springs.When these springs are mobile backward again by elongated assembling spring string back well afterwards in aggregates net feeding frame 6, send the V place on the net hand 14 just can hook the past post-tensioning of elongated assembling spring.Whole like this bed net of having assembled also just sent one stroke to move to correct position backward.At this moment just can put down row's spring.Start the machine after setting spring, machine is gone here and there net again, send net to the next position then, as repeats repeatedly just to have assembled the bed net.

The embodiment of the above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, so the equivalence that all shapes according to the utility model, structure and principle are done changes, all should be covered by in the protection domain of the present utility model.
