Therefore, the field urgently needs a spinning machine with an integrated flower suction and yarn guide mechanism to solve the above problems. Summary of the invention

[0008] The purpose of the present invention is to provide an integrated yarn suction and yarn guiding mechanism for a spinning machine, so as to solve the technical problems in the prior art that the technical solutions for yarn guiding and flying flower suction are complicated and have poor effects.

[0009] In order to achieve the above object, the present invention provides the following technical solutions:

[0010] The integrated flower suction and yarn guiding mechanism of a spinning machine comprises a yarn guiding horn, an external horn is sleeved on the outside of the yarn guiding horn; the top of the yarn guiding horn and the top of the external horn are connected and fixed by a yarn guiding arc ring; the end of the external horn away from the yarn guiding arc ring is sealed and fixedly connected with an external sleeve; the bottom end of the external sleeve is sealed and fixedly connected to the bottom end of the yarn guiding horn, and a flower suction space is formed in the outer wall area of ​​the yarn guiding horn, and the flower suction space includes a layer between the yarn guiding horn and the external horn; the flower suction space is sealed and connected with a negative pressure pipe, and the end of the negative pressure pipe away from the flower suction space is connected to an external negative pressure suction device.

[0011] The inner side wall of the yarn guide horn includes a plurality of vertically connected inclined surfaces, the wall thickness of the yarn guide horn near the top of the inclined surface is less than the wall thickness of the yarn guide horn near the bottom of the inclined surface, so that all the inclined surfaces connected end to end are in a stepped shape as a whole, and the area where the step difference is located is transitioned with a rounded corner;

[0012] The top of the inclined surface is provided with a plurality of inner negative pressure slot holes penetrating through the side wall of the yarn guide horn in a ring array.

[0013] As a preferred solution, a flying flower collection container is connected between the flower suction space and the external negative pressure suction equipment.

[0014] As a preferred embodiment, a stable inner cylinder is sandwiched between the external sleeve and the yarn guide horn, the bottom end of the external sleeve is sealed and fixedly connected to the bottom end of the stable inner cylinder, the inner wall of the stable inner cylinder is fixedly fitted to the outer wall of the yarn guide horn, and the flower suction space includes a layer between the external sleeve and the stable inner cylinder.

[0015] As a preferred embodiment, a connecting horn is fixedly connected to the top of the external sleeve, a small-diameter end of the connecting horn is fixedly connected to the external sleeve, the top of the connecting horn is fixedly connected to the external horn, and the flower suction space includes a layer between the connecting horn and the yarn guide horn.

[0016] As a preferred solution, in the main cross-sectional perspective, the yarn guide arc loop is vertical near the external horn area, and in the vertical area of ​​the yarn guide arc loop, a number of external negative pressure slots are horizontally penetrated in a circular array; the yarn guide arc loop is arc-shaped near the yarn guide horn area, and the vertical area of ​​the yarn guide arc loop and the arc-shaped area of ​​the yarn guide arc loop are connected and transitioned with rounded corners.

[0017] As a preferred solution, the yarn guide horn includes an upper yarn guide area with a large diameter facing upward, and the yarn guide horn also includes a lower anti-scratch area with a large diameter facing downward, and the upper yarn guide area and the lower anti-scratch area are integrally formed.

[0018] As a preferred solution, the negative pressure tube is fixedly connected to the external sleeve, and the negative pressure tube is sealed and connected to the flower suction space near the external sleeve area; in this mechanism, the external sleeve is used as the starting point for the generation of negative pressure, so that the air flow rate inside each internal negative pressure slot hole on the same horizontal line can be made the same, and the air flow rate inside each external negative pressure slot hole can be made the same, thereby making the flower suction efficiency easy to control, and the negative pressure suction formed in all directions of the mechanism close, so that the flower suction effect is more three-dimensional and the flower suction effect is good.

[0019] As a preferred solution, the end of the inner negative pressure slot hole close to the inclined surface is an air inlet, and the air inlet faces obliquely downward to avoid the direction of the air inlet being opposite to the moving trajectory of the yarn. This can prevent a part of the yarn from curling due to gravity and then being attracted into the inner negative pressure slot hole. On the basis of ensuring that the yarn is not disturbed by the suction of the inner negative pressure slot hole, the opening area of ​​the air inlet of the inner negative pressure slot hole can be increased, thereby enhancing the flower suction effect.

[0020] As a preferred solution, the rounded corner close to the inclined surface has a connection point M with the upper inclined surface and a connection point N with the lower inclined surface. The distance between two adjacent M's is L, and the top of the inner negative pressure slot air inlet intersects with N; the span of the inner negative pressure slot air inlet is less than L / 2, which can ensure that there is no direct contact between the air inlet and the yarn, and is beneficial to improving the stability of the yarn guiding process of the spinning machine.

[0023] The integrated yarn suction and yarn guide mechanism of the present scheme is applied in a spinning machine, and the yarn moves from top to bottom, passes through the yarn guide loop and the yarn guide horn, and under the guiding action of the arc surface of the yarn guide horn, the yarn inclined at the top to the vertical line is guided downward to a vertical state, and then the yarn enters the drafting mechanism of the spinning machine for drafting; during the use of the yarn guide horn or during transportation, the edge is an area that is easily bumped, and tiny protrusions or curling edges are inevitably produced. When the moving yarn just contacts the protrusion or curling edge, it will be hooked, and the yarn will be hooked out of the filament, destroying the integrity of the yarn structure; the yarn guide loop is designed in the present scheme so that the top opening has an outward-turned smooth arc surface, which can avoid the edge line or protrusion or curling edge of the bell mouth from scratching the moving yarn, thereby avoiding the reduction of yarn quality; the lower anti-scratch area is designed to have a bell mouth facing downward, which can also avoid the protrusion or curling edge from scratching the moving yarn, thereby avoiding the reduction of yarn quality. This scheme designs an external speaker, a connecting speaker, and an external sleeve that are interconnected and have a smooth appearance, forming a flower suction space. The negative pressure tube draws negative pressure into the flower suction space, and the flower suction space uses the external negative pressure slot to suck the flying flowers in the surrounding space in parallel to the opening direction of the external negative pressure slot. The internal negative pressure slot can suck the flying flowers inside and above the yarn guide speaker into the flower suction space, which has a three-dimensional suction space. In this scheme, the internal negative pressure slot can also attract the flying flowers attached to the yarn, so that the flying flowers are separated from the yarn, thereby improving the yarn quality. And the multi-layer internal negative pressure slots are designed in a circular array. When the yarn enters the yarn guide horn from any direction, the flying flowers on the yarn can be effectively attracted and separated by the internal negative pressure slots. The overall volume of this solution is close to that of the yarn guide horn in the prior art, and can realize the functions of the yarn guide horn and the flower suction tube at the same time. This solution uses inclined surfaces to form a stepped yarn guiding path, and uses rounded corners to transition the inclined surface joints, and the opening size and position of the internal negative pressure slots are carefully designed, so that the opening of the internal negative pressure slots will not cause wear or snagging to the yarn.

[0024] Beneficial effects:

[0025] 1. The yarn guide loop is designed in this scheme so that the top opening has a smooth curved surface that is turned outward, which can avoid the edge line, bulge or curling of the bell mouth from scratching the moving yarn and preventing the quality of the yarn from decreasing; the lower anti-scratch area is designed to have a bell mouth facing downward, which can also avoid the bulge or curling from scratching the moving yarn and preventing the quality of the yarn from decreasing;

[0026] 2. This scheme designs an external horn, a connecting horn, and an external sleeve that are interconnected and have a smooth appearance, forming a flower suction space. The negative pressure pipe draws negative pressure from the flower suction space. The flower suction space uses the external negative pressure slot to suck the flying flowers in the surrounding space in parallel to the opening direction of the external negative pressure slot. The internal negative pressure slot can suck the flying flowers inside and above the yarn guide horn into the flower suction space, which has a three-dimensional suction space and a good effect on the attraction of flying flowers.

[0027] 3. In this scheme, the internal negative pressure slots can also attract the flying fibers attached to the yarn, so that the flying fibers are separated from the yarn, thereby improving the yarn quality. In addition, the multi-layer internal negative pressure slots designed in a circular array can effectively attract and separate the flying fibers on the yarn when the yarn enters the yarn guide horn from any direction.

[0028] 4. The overall volume of this solution is close to that of the yarn guide horn in the prior art, and it can realize the functions of the yarn guide horn and the flower suction tube at the same time;

[0029] 5. This scheme uses inclined surfaces to form a stepped yarn guide path, and uses rounded corners to transition the inclined surfaces. The size and position of the internal negative pressure slot holes are carefully designed so that the opening of the internal negative pressure slot holes will not cause wear or snagging of the yarn.
