Description

[Technical Field]

[0001] This utility model relates to a dual-nozzle needle anti-rolling device. [Background Technology]

[0002] The overfeed needle pressing device is installed on the fabric feeding track of the tenter frame. Its function is to unfold the fabric selvage through the selvage peeling device and, driven by the feeding and pressing brush wheel, neatly press the fabric selvage onto the main chain needle plate of the tenter frame. In existing technology, only one edge blowing device is configured at the bottom of the needle pressing device. Therefore, for some fabrics with high elasticity and severe edge curling, re-rolling may occur during needle pressing, resulting in problems such as excessively wide needle width or inability to press the needle. [Utility Model Content]

[0003] This invention overcomes the shortcomings of the prior art and provides a dual-nozzle needle-mounted anti-rolling edge device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A dual-nozzle needle-feeding anti-rolling edge device is characterized in that: it includes a bracket, with rotating wheels on the front and rear sides of the bracket, and a belt connecting the two rotating wheels to drive the fabric movement. A dual-nozzle assembly for blowing and unfolding the rolled edge of the fabric is provided on the bracket between the two rotating wheels. The dual-nozzle assembly includes a connecting frame connected to the bracket and rotatable on the bracket. A nozzle base is provided on the connecting frame, and two rolled edge unfolding nozzles arranged side by side and rotating are provided on the nozzle base.

[0006] The dual-nozzle needle anti-rolling edge device described above is characterized in that: the bracket is provided with a bracket through hole, the two rotating wheels are arranged on the inner side of the bracket, the connecting frame and the nozzle base are arranged on the outer side of the bracket, and the two rolled edge unfolding nozzles extend into the inner side of the bracket through the bracket through hole.

[0007] The dual-nozzle needle anti-rolling edge device described above is characterized in that: the air outlet of the rolling edge unfolding nozzle is a flat opening.

[0008] The dual-nozzle needle-mounting anti-rolling edge device described above is characterized in that: a pre-rolling nozzle for blowing the fabric roll edge is provided in front of the rotating wheel located on the front side of the bracket.

[0009] The dual-nozzle needle anti-rolling edge device described above is characterized in that: a guide frame is provided at the front side of the bracket, and the rotating wheel and the rolling edge pre-expansion nozzle at the front side are respectively arranged on the guide frame.

[0010] The dual-nozzle needle anti-rolling edge device described above is characterized in that: the air outlet of the pre-rolling nozzle is a flat opening.

[0011] The dual-nozzle needle anti-rolling device described above is characterized in that: the rotating wheel is provided with a rotating wheel groove for the belt to be inserted.

[0012] The beneficial effects of this utility model are:

[0013] This utility model is equipped with a dual-nozzle assembly for blowing and unfolding the rolled edge of the fabric. The dual-nozzle assembly includes two rolled edge unfolding nozzles arranged side by side and rotating, which eliminates rolled edge in the fabric weaving process and prevents re-rolling. At the same time, the air outlet of the rolled edge unfolding nozzle is a flat opening, which effectively increases the unfolding effect. [Image Description]

[0016] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0017] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0018] like Figure 1-2As shown, a dual-nozzle needle-feeding anti-curling edge device includes a bracket 1. Rotating wheels 2 are located on the front and rear sides of the bracket 1, and a belt connecting the two rotating wheels 2 is used to move the fabric. A dual-nozzle assembly 3 is located on the bracket 1 between the two rotating wheels 2, blowing air to unfold the fabric curled edge. The dual-nozzle assembly 3 includes a connecting frame 31 connected to the bracket 1 and rotatable on the bracket 1. A nozzle base 32 is provided on the connecting frame 31, and two side-by-side rotating curl-unfolding nozzles 33 are provided on the nozzle base 32. In practical application, the device is installed on the feed rail of a tenter frame via the bracket 1. Simultaneously, a pressure brush wheel presses against the belt, causing the belt to rotate between the two rotating wheels 2 as the pressure brush wheel rotates, thus moving the fabric between the pressure brush wheel and the belt. During the fabric movement, the two curl-unfolding nozzles 33 of the dual-nozzle assembly 3 blow air onto the passing fabric curled edge, causing the fabric curled edge to unfold. Two side-by-side hem-unfolding nozzles 33 effectively eliminate hem curling during fabric weaving, preventing re-curling and allowing the fabric to unfold better before needle insertion. The hem-unfolding nozzles 33 have flat outlets to increase air pressure and more effectively enhance hem unfolding. In this design, the airflow direction of the hem-unfolding nozzles 33 can also be adjusted by rotating the connecting frame 31 and the hem-unfolding nozzles 33, further improving hem unfolding.

[0019] like Figure 1-2 As shown, the bracket 1 is provided with a bracket through hole 11, the two rotating wheels 2 are set on the inner side of the bracket 1, the connecting frame 31 and the nozzle base 32 are set on the outer side of the bracket 1, and the two rolled edge unfolding nozzles 33 extend into the inner side of the bracket 1 through the bracket through hole 11, which simplifies the overall structure, facilitates installation, and makes it easy to rotate the connecting frame 31 and the rolled edge unfolding nozzles 33 to adjust the blowing angle.

[0020] like Figure 1-2 As shown, a pre-rolling nozzle 4 for blowing fabric edges is provided in front of the rotating wheel 2 on the front side of the bracket 1. The pre-rolling nozzle 4 pre-rolls the fabric edges, so that the dual nozzle assembly 3 on the rear side can maximize the unfolding of the fabric.

[0021] like Figure 1-2 As shown, a guide frame 5 is provided at the front of the bracket 1. The rotating wheel 2 and the hem-rolling pre-unrolling nozzle 4 are respectively mounted on the guide frame 5. The guide frame 5 is provided to better guide the movement of the fabric. The air outlet of the hem-rolling pre-unrolling nozzle 4 is a flat opening to increase the blowing air pressure.

[0022] like Figure 1-2 As shown, the roller 2 is provided with roller grooves 21 for the belt to be inserted, which prevents the belt from moving on the roller 2 and allows the fabric to move better on the belt.

[0023] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
