Description

Technical Field

[0001] The invention relates to the technical field of underwear weaving, and in particular to a novel air suction and pulling device for underwear woven fabrics. Background Art

[0002] Underwear refers to clothing worn next to the body that keeps warm, and lightweight knitted underwear products have become a trend. In seamless underwear circular knitting machines, the pulling mechanism adopts a suction type, and the suction force generated by the suction fan is used to pull the fabric out of the loop forming area.

[0003] However, due to the small weight of thin and light fabrics during the weaving process, the negative pressure suction generated by the suction fan cannot provide sufficient traction, making the fabric easy to float out of the pores of the needle cylinder and the half needle disk, and causing the fabric coils to be insufficiently retracted, which can easily cause defects in the fabric or damage the knitting needles. Secondly, due to the different lengths of the fabrics, the traction force on the fabrics is insufficient, resulting in differences in the appearance of the fabric coils. The existing invention patent with patent announcement number CN113737375B discloses an induction-type seamless underwear circular knitting machine and a method for controlling the pulling force of the fabric.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figures 1 to 8 As shown, the present invention provides a novel suction and pulling device for underwear woven fabrics, comprising a frame 1, on which a winding drum 2 is arranged, and the winding drum 2 is funnel-shaped, a half disk 3 is arranged in the winding drum 2, and the winding drum 2 and the half disk 3 are used to supply fabrics for weaving, a discharge drum 4 is arranged at the bottom of the winding drum 2, and a negative pressure traction device 5 is connected to the bottom of the discharge drum 4, and the negative pressure traction device 5 is used to generate negative pressure suction to pull the fabric away from the winding drum 2 and the half disk 3, and the fabric is discharged after passing through the discharge drum 4 and the negative pressure traction device 5, and a lateral wind induction device 6 is arranged on the inner wall of the discharge drum 4, and the lateral wind induction device 6 is used to provide lateral attraction force in the horizontal direction.

[0020] In actual application of this application, the half disk 3 and the winding drum 2 are not connected (specifically refer to the invention patent with patent announcement number CN113737375B, which discloses an inductive seamless underwear circular machine and a method for controlling fabric pulling force), and both are located inside the underwear circular machine. The underwear circular machine (not shown in the accompanying drawings) is a prior art, and its technical principle is not elaborated in detail. The frame 1 is a bracket inside the underwear circular machine for installing the half disk 3 and the winding drum 2. Its shape in the accompanying drawings is only an example. The fabric is woven in the half disk 3 and the winding drum 2, and the fabric is adsorbed and pressed down by the negative pressure suction force generated by the negative pressure traction device 5.

[0021] During weaving, the negative pressure traction device 5 generates negative pressure suction to provide pulling force to the fabric, pulling the fabric into the discharge cylinder 4, and entering the negative pressure traction device 5 through the discharge cylinder 4, and then unloading from the negative pressure traction device 5.

[0022] In this embodiment, the specific structural principle of the negative pressure traction device 5 refers to the induction-type seamless underwear circular knitting machine and the method for controlling the fabric pulling force disclosed in the invention patent with patent announcement number CN113737375B, and specifically refers to the pulling device, fabric conveying pipeline, discharge bell mouth and discharge cover in the invention patent (CN113737375B). The negative pressure traction device 5 in this application is a collection of the above structures (pulling device, fabric conveying pipeline, discharge bell mouth and discharge cover) listed in the invention patent (CN113737375B). The technical principle of the negative pressure traction device 5 will not be elaborated in detail here.

[0023] After the fabric is pulled into the discharge barrel 4 by the negative pressure traction device 5, the lateral air induction device 6 provides a horizontal lateral attraction force, so that the fabric is evenly stressed in the horizontal direction when passing through the discharge barrel 4, so that the fabric is evenly stressed when pulled by the negative pressure traction device 5, thereby ensuring the weaving quality of the fabric and preventing the fabric from swinging after entering the discharge barrel 4 and affecting the pulling effect of the negative pressure traction device 5 on the fabric in the half plate 3.

[0024] Furthermore, a sensing device is provided on the winding drum 2 and the half disk 3, and the sensing device is used to sense the pulling force exerted on the fabric during the weaving process. Specifically, reference is made to the sensing device in the invention patent with patent announcement number CN113737375B, which discloses an induction-type seamless underwear circular machine and a method for controlling the pulling force of the fabric.

[0025] The lateral air-inducing device 6 includes an annular tube 601 arranged on the outer wall of the discharge barrel 4, and a plurality of air-inducing plates 602 evenly distributed around the center line of the discharge barrel 4 are commonly arranged on the outer wall of the annular tube 601 and the side wall of the discharge barrel 4, and the annular tube 601 is connected with the interior of the discharge barrel 4 through the plurality of air-inducing plates 602, and the plurality of air-inducing plates 602 are commonly connected with an adjusting component 604, and the adjusting component 604 is used to adjust the size of the channel on the air-inducing plate 602 connecting the annular tube 601 and the discharge barrel 4, and a plurality of air pipes 603 corresponding to the air-inducing plates 602 are arranged inside the annular tube 601, and the plurality of air pipes 603 are commonly connected with a first air pump.

[0026] The first air pump is started to suck the multiple air pipes 603, thereby generating negative pressure suction in the annular tube 601, and generating a negative pressure adsorption effect on the fabric in the discharge cylinder 4 through the channels on the multiple wind guide plates 602. Since the wind guide plates 602 are evenly distributed, the horizontal suction force on the fabric is evenly distributed, so that the fabric remains stable under the action of the negative pressure suction, ensuring that the pulling force of the negative pressure traction device 5 on the fabric in the winding cylinder 2 is evenly distributed, avoiding the fabric from shaking drastically and blocking the channel connecting the discharge cylinder 4 and the winding cylinder 2.

[0027] The size of the channel on the air guide plate 602 is adjusted by adjusting the component 604 to adjust the suction force in the discharge barrel 4, thereby adjusting the suction force according to fabrics with different parameters such as different materials and different weights to ensure the stability of the fabric during the discharge process.

[0028] The air induction plate 602 includes a fixed plate 605, and the annular tube 601 and the discharge barrel 4 are jointly provided with mutually aligned mounting grooves, and the fixed plate 605 is arranged in the mounting grooves on the annular tube 601 and the discharge barrel 4, and is flush with the inner wall of the annular tube 601, and a plurality of air induction holes 606 are provided on the fixed plate 605. A sealing plate 607 is slidably connected to one side of the fixed plate 605 facing the inside of the annular tube 601, and the sealing plate 607 is connected to the adjustment component 604, and a plurality of adjustment holes 608 that can respectively correspond to the plurality of air induction holes 606 are provided on the sealing plate 607.

[0029] The adjustment component 604 simultaneously drives multiple sealing plates 607 to slide on the corresponding fixed plates 605, thereby adjusting the relative position between the adjustment hole 608 and the corresponding wind induction hole 606, so that the size of the connecting part between the adjustment hole 608 and the wind induction hole 606 becomes larger or smaller, so as to change the cross-sectional area of ​​the path through which the airflow passes, thereby adjusting the magnitude of the adsorption force on the fabric.

[0030] The fixing plate 605 is flush with the inner wall of the annular tube 601 to ensure that the sealing plate 607 can slide normally and avoid interference with the inner wall of the annular tube 601 .

[0031] Furthermore, one side of the fixing plate 605 may also extend into the interior of the annular tube 601 , as long as it is ensured that the inner wall of the annular tube 601 does not interfere with the movement of the sealing plate 607 .

[0032] The adjustment assembly 604 includes an outer gear ring 609 fixedly connected to the outer walls of the plurality of sealing plates 607 , a gear 610 meshing on the outer gear ring 609 , and the gear 610 is installed on the inner wall of the annular tube 601 via a rotating shaft, and the rotating shaft is connected to a driving device.

[0033] The gear 610 is driven to rotate by a driving device such as a motor to drive the rotating shaft, thereby driving the outer gear ring 609 to rotate, and multiple sealing plates 607 rotate synchronously with the outer gear ring 609, thereby adjusting the relative position between the sealing plate 607 and the fixed plate 605, and then adjusting the size of the connecting part between the adjustment hole 608 and the wind inlet hole 606.

[0034] A positioning convex plate 611 is provided on the side wall of the annular tube 601 close to the discharge barrel 4 , and two positioning blocks 612 are provided at the bottom of the outer gear ring 609 , and the positioning convex plate 611 is located between the two positioning blocks 612 .

[0035] When one of the positioning blocks 612 abuts against the positioning convex plate 611 , the plurality of air inlet holes 606 are aligned with the plurality of adjustment holes 608 , and when the other positioning block 612 abuts against the positioning convex plate 611 , the sealing plate 607 closes the plurality of air inlet holes 606 .

[0036] The moving range of the positioning protrusion 611 is limited by two positioning blocks 612, so that when the adjustment component 604 adjusts the position of the sealing plate 607, the sealing plate 607 can be used to accurately close the air intake hole 606, or the air intake hole 606 and the adjustment hole 608 can be completely aligned. Not only is the adjustment more accurate, but it also has the shortest stroke to achieve the effect of adjusting the negative pressure suction force of the fabric.

[0037] The air inlet holes 606 are obliquely opened on the fixing plate 605 , the adjustment holes 608 are horizontally arranged on the sealing plate 607 , and the center of one end of each air inlet hole 606 can coincide with the center of one end of the corresponding adjustment hole 608 .

[0038] The negative pressure suction force generated by the first air pump can have a downward pulling effect on the fabric, assisting the negative pressure traction device 5 to pull the fabric, thereby improving efficiency.

[0039] An auxiliary unloading device 7 is also provided on the inner wall of the discharge barrel 4, and the auxiliary unloading device 7 is used to assist the fabric to be separated from the winding barrel 2 and the half plate 3. The auxiliary unloading device 7 includes a plurality of connecting shafts 701 rotatably arranged on the inner wall of the discharge barrel 4 and an annular seat 707 fixedly arranged on the outer wall of the discharge barrel 4, and the plurality of connecting shafts 701 are evenly distributed around the center line of the discharge barrel 4, and each connecting shaft 701 is evenly arranged with a plurality of elastic sheets 702 around the axis, and the inner wall of the discharge barrel 4 is provided with a plurality of connecting shafts 701 for mounting. The side groove 703 and the annular seat 707 are provided with an annular groove 704 which is connected with the plurality of side grooves 703, and the height of the inner bottom of the annular groove 704 is smaller than the height of the inner bottom of the side groove 703, and the height of the inner top of the annular groove 704 is larger than the height of the inner top of the side groove 703, and a plurality of blowing pipes 705 are arranged in the annular groove 704, and the plurality of blowing pipes 705 are commonly connected with a second air pump, and a plurality of air outlet grooves 706 which are connected with the outside of the annular seat 707 are arranged at the inner top of the annular groove 704 corresponding to the plurality of blowing pipes 705.

[0040] The second air pump is started and blows the elastic sheets 702 on the multiple connecting shafts 701 through the multiple blowing pipes 705, so that the multiple connecting shafts 701 rotate, thereby making the elastic sheets 702 on the multiple connecting shafts 701 cyclically contact with the fabric and exert a downward force on the fabric to assist in the unloading of the fabric.

[0041] By setting an air outlet groove 706 at the top of the annular groove 704 and setting the blowing pipe 705 at the inner bottom of the annular groove 704, the gas blown out of the blowing pipe 705 can directly enter the outside of the annular seat 707 through the air outlet groove 706 when the elastic sheet 702 is blown to drive the connecting shaft 701 to rotate, thereby avoiding an upward force on the fabric inside the discharge barrel 4 and ensuring the stability of the fabric.

[0042] Furthermore, the height of the auxiliary unloading device 7 in the discharge cylinder 4 should be relatively low. When the auxiliary unloading device 7 contacts the fabric, the top of the fabric should be at the top of the discharge cylinder 4 and about to leave the winding cylinder 2.

[0043] The edges of the elastic sheet 702 are all provided with arc chamfers to avoid damage to the fabric.

The protection scope of the present application is defined by the claims.
