Abstract

The utility model provides a jacquard head in a structure as follows. The jacquard head comprises a head rack, an upper knife lifting board and a lower knife lifting board, and both sides of the head rack are provided with knife lifting board driving gears; the jacquard head is characterized in that both sides of the head rack are provided with two guide posts, respectively, the guide posts are fixed on wallboards on both sides of the head rack respectively, and two guide posts on the wallboard of each side are arranged at two ends of the upper knife lifting board and the lower knife lifting board respectively; and the upper knife lifting board and the lower knife lifting board are in sliding fit with the guide posts by guide sleeves, respectively, and the guide sleeves are connected with the knife lifting board driving gears. One guide post on each side of the original head rack is changed into two guide posts which are evenly distributed to effectively ensure the movement stability of the upper knife lifting board and the lower knife lifting board and avoid the inclinations of the upper knife lifting board and the lower knife lifting board, the movement of the knife lifting boards are more stable, thus the uniform movement of jacquard needles is can be ensured, and the production quality of products can be ensured.

Description

The jacquard tap

Technical field:

The utility model relates to the Weaving device technical field, relates to a kind of jacquard tap specifically.

Background technology:

In the prior art; The moving back and forth up and down through eccentric mechanism of plate of griffing of jacquard realized; The plate of griffing that wherein is arranged in leading frame both sides realizes that through a guide pillar its concrete structure is in the stability of the process of moving up and down: in the both sides, front and back of leading frame a guide pillar is arranged all, the two ends of guide pillar are mounted on the wallboard of leading frame; Griffe plate and a guide pin bushing and fix; Guide pin bushing and guide pillar sliding fit, like this, the plate of griffing of both sides just can stable moving up and down under eccentric drive before and after the leading frame.But keep at present and griffe plate and move stable structure and also have following defective: single guide pillar all is arranged on griffes the midway of plate; Installation accuracy and assembly precision to guide pillar all have higher requirement; Careless slightlyly will cause run-off the straight between guide pillar and the guide pin bushing, cause that to griffe the step at plate two ends inconsistent, and then cause that the step of knitting needle is disorderly; Therefore, this rock-steady structure is unfavorable for keeping the stable of product quality.

The utility model content:

For solving above-mentioned technical problem, the utility model provides a kind of can effectively keeping to griffe plate and move stability, guarantees the jacquard tap of product quality.

The technical scheme of the utility model is; A kind of jacquard tap with following structure is provided; It comprises leading frame, on griffe plate, griffe plate down, the both sides of described leading frame are equipped with griffes the plate driving mechanism, it is characterized in that: the both sides of described leading frame are respectively equipped with two guide pillars; Described guide pillar is separately fixed on the wallboard of leading frame both sides, and two guide pillars on every framed side wallboard are arranged in the position of griffing plate and griffing the plate two ends down; Griffe on described plate with under griffe plate respectively through guide pin bushing and guide pillar sliding fit, described guide pin bushing with griffe the plate driving mechanism and be connected.

After adopting said structure, the utlity model has following advantage:

Change the guide pillar of the every side of original leading frame into two by one; And evenly cloth postpone can effectively guarantee to griffe plate with griffe the stability that plate moves down; Avoid griffing plate with griffe down the plate run-off the straight, griffe the mobile comparatively stable of plate, like this; The step that just can guarantee knitting needle is consistent, and the quality of production of product can be guaranteed.

As improvement, the described plate driving mechanism of griffing is the eccentric wheel driving mechanism.The eccentric wheel driving mechanism is common structure in the jacquard tap, reliable and practical, helps saving design and manufacturing cost.

Description of drawings:

Fig. 1 is the front view of the utility model jacquard tap;

Fig. 2 is the side view of the utility model jacquard tap;

The specific embodiment:

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

Like Fig. 1, shown in Figure 2; The utility model jacquard tap; It comprises leading frame 1, on griffe plate 2, griffe plate 3 down; The both sides of tap frame 1 are provided with and are equipped with wallboard 1.1, also distinguish the both sides of corresponding setting at leading frame 1 and be used to drive the plate driving mechanism of griffing of griffing plate 2 and griffing plate 3 down.

Reaching the stable plate of griffing in the utility model moves stable technical scheme and is: be respectively equipped with two guide pillars 4 in the both sides of leading frame 1; The two ends of guide pillar 4 are separately fixed on the wallboard 1.1 of leading frame 1 both sides; Two guide pillars 4 on every framed side wallboard 1.1 all be arranged near on griffe plate 2 with griffe the position at plate 3 two ends down; So comparatively even, help guaranteeing griffing the plate two ends move synchronously; On griffe plate 2 with griffe plate 3 down respectively through guide pin bushing 5 and guide pillar 4 sliding fits, guide pin bushing 5 with griffe the plate driving mechanism and be connected.Griffing the concrete structure of plate driving mechanism is eccentric wheel driving mechanism 6 commonly used in the jacquard tap, and the application of eccentric wheel driving mechanism in the jacquard tap belongs to known prior art, just do not state tired at this.

Claims

1. jacquard tap; It comprises leading frame (1), on griffe plate (2), griffe plate (3) down; The both sides of described leading frame (1) are equipped with griffes the plate driving mechanism; It is characterized in that: the both sides of described leading frame (1) are respectively equipped with two guide pillars (4), and described guide pillar (4) is separately fixed on the wallboard (1.1) of leading frame (1) both sides, and two guide pillars (4) on every framed side wallboard (1.1) are arranged in the position of griffing plate (2) and griffing plate (3) two ends down; Griffe on described plate (2) and under griffe plate (3) respectively through guide pin bushing (5) and guide pillar (4) sliding fit, described guide pin bushing (5) with griffe the plate driving mechanism and be connected.
