Abstract

The utility model relates to an additional structure for a straw mat brander, particularly a quick grass mat braiding jumper preventing mechanism for mass production. The utility model is composed of a small eccentric wheel, a sliding block rack and a wobble plate, wherein the long radius of the small eccentric wheel which is arranged on a rotating shaft has a 90 DEG included angle with a pin roll of a large eccentric wheel, the sliding block rack is arranged on the parietal margin of the small eccentric wheel and supported on the frame vertical guideway, one end of the wobble plate is pivoted on the top of the sliding block rack, the other end is movably sheathed with the wobble plate of one end of a control filament plate. Thus, the utility model can prevent jumper during weaving and improve production efficiency.

Description

The straw mat braiding machine prevent wire jumper mechanism

The utility model relates to a kind of additional structure of straw mat braiding machine, and the quick straw mat braiding that is particularly suited for producing in enormous quantities prevents wire jumper mechanism.

At present, the straw mat demand of vegetable growing insulation usefulness increases day by day, and existing straw mat machine is to control the line plate to the right limit with the pivot pin on the large eccentricity wheel through depression bar, pendulum plate, bump, in the motion of eccentric wheel pivot pin, the braiding of eedle hook line, but owing to control the line plate to the limit of the right, line is motionless, behind the eedle hook line, sometimes the line cunning is prone to wire jumper less than going in the pinhock during braiding, often knits with artificial the benefit.

In view of this, what the purpose of this utility model provided a kind of straw mat braiding machine prevents wire jumper mechanism, drives control panel with the small eccentricity wheel that rotates synchronously with the large eccentricity wheel and does additional movement, makes line send into and strain in pinhock.

If the purpose of this utility model is achieved in that it is provided with the small eccentricity wheel that becomes 90 ° of angles with its major radius with the bearing pin of large eccentricity wheel in rotating shaft, on the slider frame that is supported on the apical margin of this small eccentricity wheel on the frame vertical guide rail, on frame, be provided with the one end and be articulated in the slider frame top, and the other end is actively socketed on the pendulum plate of control line plate one termination.

The rolling bearing of splicing on the above-mentioned eccentric wheel outer rim.

Above-mentioned pendulum plate is the square fork.

Owing to adopt such scheme: can prevent wire jumper in the braiding, enhance productivity greatly simultaneously.

Below in conjunction with drawings and Examples the utility model is further specified.

Among the figure: 1, rotating shaft 2, large eccentricity wheel 21, bearing pin 3, small eccentricity wheel

31, rolling bearing 4, slider frame 5, pendulum plate 6, control line plate

61, bearing pin 62, line hole 7, frame 8, eedle

Present embodiment comprises rotating shaft 1, large eccentricity wheel 2, small eccentricity wheel 3, slider frame 4, pendulum plate 5, control line plate 6 and frame 7, as shown in Figure 1, 2;

Rotating shaft 1 flatly is bearing on the frame 7, rotates (genus prior art) by motor, the moving rotating shaft 1 of belt transmission pivot.

Large eccentricity wheel 2 is fixed in the rotating shaft 1 and with the bearing pin on it 21 and drives move (genus prior aries) such as eedles 8 through each driving member (not shown).

Small eccentricity wheel 3 is fixed in the rotating shaft 1 and at its outer rim rolling bearing 31 of splicing with taking turns 21 one-tenth 90 ° of angles of bearing pin of 2 with its major radius and large eccentricity.

Slider frame 4 is formed by guide post and with the pull bar that adjusting nut connects, and guide post is supported in rolling bearing 31 apical margins of small eccentricity wheel 3 and is slidingly fitted on the vertical guide rail of frame 7, and upper and lower rectilinear motion is made in restriction.

Pendulum plate 5 is square forks, and is suspended on swing on the frame 7 with the activity of place, right angle, and horizontal rod end articulates the pull bar top of slider frame 4, and vertically rod end is actively socketed on the control panel 6 termination bearing pins 61.

Control line plate 6 is bearing on the horizontal guide rail of frame 7 (on the two perpendicular framves) slidably, under the push-and-pull of pendulum plate 5, can move horizontally through its bearing pin 61, and in addition, control line plate 6 is provided with several and uses (genus prior art) with eedle 8 corresponding line holes 62 for wearing weaving thread.

The operation principle of present embodiment is as follows:

When the bearing pin 21 of large eccentricity wheel 2 forwards left side horizontal level (just driving eedle 8 moves upward parallel with 62 bottoms, line hole) in the direction of the clock to, at this moment, the major radius of small eccentricity wheel 3 forwards the summit to, and promote control line plate 6 by slider frame 4, pendulum plate 5 and move right right limit, make line hole 62 and eedle 8 at a distance of 6～8 millimeters (adjusting), as shown in Figure 3 with the adjusting nut on the slider frame 4.

When the bearing pin 21 of large eccentricity wheel 2 changes 90 ° to the limit when (just eedle 8 to the limit), at this moment, small eccentricity is taken turns 3 major radius and is forwarded the right horizontal level to, and by slider frame 4, pendulum plate 5 pulling control line plates 6, weaving thread is sent in the hook of eedle 8, as shown in Figure 4.

When the bearing pin 21 of large eccentricity wheel 2 forwarded the right horizontal level to, eedle 8 moved downward the weaving thread hook, and needle point is parallel with 62 bottoms, line hole, at this moment, small eccentricity is taken turns 3 major radius and is forwarded end point to, and drives control line plate 6 to left side limit, line is strained as shown in Figure 5 in pinhock.

When the bearing pin 21 of large eccentricity wheel 2 drives eedles 8 and puts on earth, at this moment, the major radius of small eccentricity wheel 3 will control line plate 6 and shift position shown in Figure 4 onto to left side horizontal level, and loose ends relaxes and send the grass pulling woven line that bed travels forward, and weaves, as shown in Figure 6.

When the bearing pin 21 of large eccentricity wheel 2 changes 90 ° again, repeat motion shown in Figure 3, no longer repeat.
