Description

Technical Field

[0001] The utility model relates to the technical field of fabric spraying devices, in particular to a soft woven fabric spraying mechanism. Background Art

[0002] The airflow softening machine is a device that modifies the physical properties of fabrics, releasing internal stresses generated during processing and achieving a certain degree of bulk. Its operating principle is that a high-speed airflow generated by a high-speed fan is delivered through a pipeline to the fabric ejection mechanism. The fabric ribbon is then ejected at a very high speed, impacting a fence near the ejection pipe outlet before falling into a fabric storage tank. During this energy conversion process, the fabric converts kinetic energy into fiber deformation energy.

[0003] In current fabric ejection mechanisms, one end of a feed tube extends into a Venturi tube. Once inside, the airflow is accelerated and blown out of a discharge tube, carrying the fabric within the feed tube. A gap between the feed tube and the Venturi tube helps vary the airflow, affecting the speed at which the fabric is carried out. However, the existing structure is limited in its ability to adjust the airflow according to the type of fabric, limiting its applicability. Utility Model Content

[0004] The purpose of the present invention is to solve the problem mentioned in the above-mentioned background technology that the airflow size cannot be adjusted and the applicability is relatively narrow.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A soft woven fabric spraying mechanism comprises an air supply pipe and a venturi tube connected to the air supply pipe, wherein the air supply pipe is provided with a suction pipe, the first end of the suction pipe extends into the interior of the venturi tube, the first end of the suction pipe is provided with a fixed cylinder, one end of the fixed cylinder is fixedly connected to a fixed block, the fixed block is fixed to the suction pipe, a gap is formed between the fixed cylinder and the suction pipe, the first end of the suction pipe is sleeved with an adjusting cylinder, one end of the adjusting cylinder extends into the gap, a spring is provided in the gap, and the two ends of the spring are respectively fixed to the adjusting cylinder and the inner wall of the fixed block.

[0007] The regulating cylinder is placed in the venturi tube, and the regulating cylinder is also connected to an regulating mechanism for driving the regulating cylinder to slide axially relative to the suction pipe.

[0008] Preferably, the fixing block is provided with a conical surface, which reduces airflow resistance.

[0009] Preferably, the opening of the gap faces the direction of airflow.

[0010] Preferably, the diameter of the adjusting cylinder is smaller than the diameter of the fixing cylinder.

[0011] Preferably, the second end of the suction pipe extends to the outside of the air supply pipe, and one end of the adjustment mechanism is connected to the adjustment cylinder, and the other end is connected to the suction pipe outside the air supply pipe.

[0012] Preferably, the adjustment mechanism includes a connecting plate, one end of which is fixed to the adjustment cylinder, and the other end of which is slidably connected to the suction pipe.

[0013] Preferably, the connecting plate is located inside the suction pipe so that the airflow can flow better, and the upper surface of the connecting plate contacts the inner top wall of the suction pipe.

[0014] Preferably, plate body one and plate body two are fixed at both ends of the connecting plate respectively, plate body one is fixedly connected to the inner top wall of the adjusting cylinder, a slide groove is provided on the suction tube, the width of the slide groove is smaller than the width of the connecting plate, and plate body two passes through the slide groove upward.

[0015] Preferably, a support is provided on the upper side of the slide groove, a bolt is threadedly connected to the support, and one end of the bolt is threadedly connected to the second plate body.

[0016] Preferably, a shielding plate contacting the lower surface of the connecting plate is provided in the suction pipe, and the shielding plate supports the connecting plate.

[0017] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0018] 1. As the inner diameter of one end of the Venturi tube gradually increases, when the regulating tube moves through the connecting plate, the gap between the regulating tube and the inner wall of the Venturi tube changes, thereby affecting the air flow velocity, and thus being suitable for different fabric softening requirements;

[0019] 2. The adjustment cylinder is driven to slide by the rotation of the bolt, and the adjustment accuracy is high. As a result, the gap adjustment accuracy between the Venturi tube and the feed pipe is relatively high, and the softening effect of the fabric is better.

[0020] 3. The connecting plate is located in the suction tube and is fixed to the regulating tube through the plate body, so that the regulating mechanism does not block the airflow and the airflow can flow better. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A fixed cylinder 5 is provided at the first end of the suction tube 4. One end of the fixed cylinder 5 is fixedly connected to a fixed block 6, which is fixed to the suction tube 4 and has a tapered surface 61 thereon. This tapered surface 61 reduces airflow resistance.
