Abstract

The utility model relates to a plastic zipper making machine, which solves the problem of accurately skipping a stitch. A skipping stitch device for the zipper making machine comprises a machine body, a movable seat, an induction switch, a clamping block and a positioning seat. Rails are arranged on the machine body. The utility model is characterized in that a motion cylinder is arranged on a movable seat, the motion cylinder is provided with a motion arm, the motion arm is combined with a plate, and the clamping block is combined on the plate. The utility model is used on the zipper making machine for skipping the stitch.

Description

The skipping stitch device of zipper fabrication machine

The utility model relates to the plastic fastener maker, and the continuous injection of cloth being done zipper teeth that refers in particular to a kind of plastic fastener maker is come out or done and jump the operating mechanism that cun sky is established.

Existing plastic fastener maker, when work, with continuous cloth, through the injection mold injects go out zipper teeth, and the length of slide fastener is need preset by it, make cloth do injecting continuously of zipper teeth or cloth is done the sky of jumping cun establish, existing doing jumped very little operating mechanism, done predicting by inductive switch, so that connecting rod promotes a stop block lifting, when leaving, moves between seat and positioning seat stop block, cloth just can be drawn to move a distance, so has just stayed on the cloth and establish the position, because connecting rod is the mechanical type action, after using continuously, will produce loosening and impact sound because of abrasion; In addition, because the spacing of zipper teeth must accurately install, therefore, the displacement that moves seat requires and must accurately could guarantee workmanship.

The displacement that the purpose of this utility model provides a kind of satisfied mobile seat is accurate, overcomes the skipping stitch device of the loosening zipper fabrication machine of abrasion.

The purpose of this utility model is achieved in that the skipping stitch device of zipper fabrication machine, it comprises basic machine, moves seat, inductive switch, stop block and positioning seat, rail on the basic machine, mobile seat is located on the rail, it is characterized in that: moving on the seat has displacement cylinder, displacement cylinder has movement arm, and movement arm is combined with plate, is combined with stop block on the plate.

Above-mentioned design utilizes the action of displacement cylinder, can make the stop block lifting, makes stop block and positioning seat become contact or separate, makes displacement accurate to change the displacement that moves seat, to reach, and has avoided the shortcoming of becoming flexible with the connecting rod generation originally.

Below by drawings and Examples the utility model is described further again:

Fig. 1 is the utility model embodiment perspective exploded view;

Fig. 2 is the main schematic diagram of looking for the utility model embodiment makes up;

Fig. 3,4,5 is the action diagram of Fig. 2;

Fig. 6 is the schematic top plan view of Fig. 2.

As shown in Figure 1, 2: the utility model comprises basic machine 1, moves seat 2, inductive switch 11, stop block 25 and positioning seat 12, rail 10 on the basic machine 1, moving seat 2 is located on the rail 10, it is characterized in that: moving on the seat 2 has displacement cylinder 21, displacement cylinder 21 has movement arm 22, movement arm 22 is combined with plate 23, is combined with stop block 25 on the plate 23.Utilize the movement arm 22 of displacement cylinder 21, be engaged on the plate 23 by terminal, plate 23 is with spiro connecting element 24 affixed stop blocks 25, but makes stop block 25 oscilaltions.When displacement cylinder 21 rose, stop block 25 was in the higher position.

As Fig. 3, when moving seat 2 near positioning seat 12, stop block 25 can contact and withstand on positioning seat 12, and like this, seat 2 moves small distance and when retreating, cloth is pulled a smaller length when moving, and makes cloth be injected sprocket continuously.

As Fig. 4, when sprocket and chain between cog need form jumping that sky establishes cun, displacement cylinder 21 can descend.

As Fig. 5, when moving seat 2 near positioning seat 12, stop block 25 minutes is passed through by positioning seat 12 bottoms two sides, and therefore, moving seat 2 becomes and move big distance.When mobile seat 2 retreated, the cloth of the folder that drags stayed big distance, and at this moment, when being injected sprocket once more, the sprocket of this a sprocket position and a last chain just forms a blank spacing.

As shown in Figure 6, the amount of movement of mobile seat 2 can change according to the needs of slide fastener length.Wherein, positioning seat 12 has two screw thread embedding up and down to press from both sides a screwed pipe 14, screwed pipe 14 is combined in again and moves seat 2, and positioning seat 2 itself snaps into the set locating hole 16 of basic machine 1 with setting element 15 and fixes or positioning seat 12 breaks away from locating holes 16 and seat 2 is moved in contact with screw.In a word, positioning seat 12 can change the position, make to move 2 one-tenths different amount of movements of seat, this adjustments work mat positioning seat 12 and be provided with handle 13, handle 13 binding positioning seats 12 up and down two finish.Handle 13 unclamps, can make positioning seat 12 up and down two separately no longer clamp screwed pipe 14, also can utilize the rotation of screwed pipe 14, make fine setting to change the distance that moves 12 of seat 2 and positioning seats.

Therefore the utility model utilizes displacement cylinder 21 to reach moving of stop block 25, and loosening and impact sound no longer take place; And the amount of movement that moves seat 2 can be done big distance and fine setting.Reach the accurate purpose of the spacing that makes zipper teeth.
