[0004] However, when placing the yarn bobbin, the textile yarn rack in the above-mentioned prior art cannot adjust the height of the yarn bobbin on the lead-in column, and it is difficult to fix the yarn bobbin at any position on a lead-in column. In this way, during the transportation and guiding of the yarn, it is easy for a large height difference between the yarn bobbin and the yarn to occur, which can easily increase the tension of the yarn, thereby increasing the wear and consumption of the yarn and increasing the possibility of yarn breakage during the leading process. Summary of the Invention

[0005] The purpose of the utility model is to provide a textile yarn lead frame to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a textile yarn lead frame, comprising: a column and a cross bar, columns are provided at both ends of the cross bar, swivel seats are provided on both sides of the top of the cross bar, a lead plate is provided on the top of the swivel seat, an elastic air bag is provided inside the lead plate, a top cover is provided on the top of the lead plate, an air charging and discharging pipe is provided on the top of the top cover, the air charging and discharging pipe is connected with the elastic air bag, a driving motor is provided on the bottom surface of the cross bar, one end of the output shaft of the driving motor is fixedly connected to the swivel seat, a lower oblique rod is provided on one side of the lower half of the column, an upper oblique rod is provided on one side of the top of the column, a screw rod is provided between the lower oblique rod and one end of the upper oblique rod, a guide wheel is provided on the outside of the screw rod, a guide rod is provided between the lower oblique rod and one end of the upper oblique rod, and the guide wheel and the guide rod are slidably connected.

[0008] Furthermore, the rotating seat is provided with four lead uprights, which are evenly arranged circumferentially on the rotating seat, with gaps left between the lead uprights, and one side of the outer wall of the elastic airbag protrudes from the gap.

[0009] Furthermore, a servo motor is provided on one side of the bottom of the lower oblique rod, and one end of the output shaft of the servo motor is fixedly connected to the screw rod.

[0010] Furthermore, the screw rod and the guide wheel are connected via a screw rod nut, and the screw rod nut can convert the rotational motion of the screw rod into the linear motion of the guide wheel.

[0011] Furthermore, a guide sleeve is provided on one side of the outer wall of the guide wheel, the guide sleeve is sleeved on the outside of the guide rod, and the guide sleeve is slidably connected to the guide rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The utility model realizes that when a textile yarn lead frame is used, the yarn bobbin is sleeved on the outer side of the lead plate, and then the charging and discharging air pipe is connected to the air pump. After manually adjusting the height of the yarn bobbin on the lead plate, the elastic air bag is inflated through the charging and discharging air pipe, so that the elastic air bag expands. The expanded part of the elastic air bag protrudes from the gap between the lead plate and abuts against the inner wall of the yarn bobbin, thereby fixing the yarn bobbin on the outer side of the lead plate. By charging and discharging the elastic air bag, the height of the yarn bobbin can be freely adjusted according to the height of the yarn; the height difference between the yarn and the yarn bobbin is reduced, and the loss of the yarn during the lead process is reduced.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figures 1-4 The utility model provides a technical solution: a textile yarn lead frame, comprising: a column 1 and a cross bar 2, with columns 1 fixed at both ends of the cross bar 2, and a swivel seat 3 rotatably connected on both sides of the top of the cross bar 2, a lead vertical plate 4 is fixed on the top of the swivel seat 3, an elastic air bag 5 is provided inside the lead vertical plate 4, a top cover 6 is fixed on the top of the lead vertical plate 4, and an air charging and discharging pipe 7 is provided on the top of the top cover 6, and the air charging and discharging pipe 7 is connected to the elastic air bag 5. A driving motor 15 is fixed to the bottom surface of the cross bar 2, and one end of the output shaft of the driving motor 15 is fixedly connected to the swivel seat 3. A lower oblique rod 8 is fixed to one side of the lower half of the column 1, and an upper oblique rod 12 is fixed to one side of the top of the column 1, and a screw rod 10 is rotatably connected between the lower oblique rod 8 and one end of the upper oblique rod 12. A guide wheel 11 is provided on the outside of the screw rod 10, and a guide rod 13 is fixed between one end of the lower oblique rod 8 and the upper oblique rod 12, and the guide wheel 11 and the guide rod 13 are slidably connected.

[0022] The charging and discharging air pipe 7 is connected to the top cover 6 via a rotary joint, which is in communication with the elastic airbag 5. Four lead plates 4 are provided on the turntable 3. The four lead plates 4 are evenly arranged circumferentially on the turntable 3. There are gaps between the lead plates 4, and one side of the outer wall of the elastic airbag 5 protrudes from the gap. The charging and discharging air pipe 7 is connected to the air pump. After manually adjusting the height of the yarn bobbin on the lead plate 4, the elastic airbag 5 is inflated through the charging and discharging air pipe 7, causing the elastic airbag 5 to expand. The expanded part of the elastic airbag 5 protrudes from the gap between the lead plates 4 and abuts against the inner wall of the yarn bobbin, thereby fixing the yarn bobbin on the outside of the lead plate 4. By charging and discharging the elastic airbag 5, the height of the yarn bobbin can be freely adjusted according to the height of the yarn, reducing the height difference between the yarn and the yarn bobbin and reducing the loss of the yarn during the lead-in process.

[0023] A servo motor 9 is fixed to one side of the bottom of the lower inclined rod 8, and one end of the servo motor 9 output shaft is fixedly connected to a screw rod 10. The screw rod 10 and the guide wheel 11 are connected by a screw nut, which can convert the rotational motion of the screw rod 10 into the linear motion of the guide wheel 11. A guide sleeve 14 is fixed to one side of the outer wall of the guide wheel 11. The guide sleeve 14 is sleeved on the outside of the guide rod 13 and is slidably connected to the guide rod 13. During the yarn feeding process, the servo motor 9 drives the screw rod 10 to rotate. The screw nut cooperates with the guide rod 13 to convert the rotational motion of the screw rod 10 into the up and down linear motion of the guide wheel 11, guiding the yarn in the up and down direction, facilitating the uniform winding and unwinding of the yarn on the yarn feeding wheel, and avoiding clutter during the yarn feeding process. The sliding connection between the guide sleeve 14 and the guide rod 13 can prevent the guide wheel 11 from rotating with the rotation of the screw rod 10, ensuring the smooth raising and lowering of the guide wheel 11.

[0024] When the textile yarn lead frame is in use, the yarn bobbin is put on the outside of the lead vertical plate 4, and then the charging and discharging air pipe 7 is connected to the air pump. After manually adjusting the height of the yarn bobbin on the lead vertical plate 4, the elastic airbag 5 is inflated through the charging and discharging air pipe 7, so that the elastic airbag 5 expands. The expanded part of the elastic airbag 5 protrudes from the gap between the lead vertical plates 4 and abuts against the inner wall of the yarn bobbin, thereby fixing the yarn bobbin on the outside of the lead vertical plate 4. By charging and discharging the elastic airbag 5, the height of the yarn bobbin can be freely adjusted according to the height of the yarn; the height difference between the yarn and the yarn bobbin is reduced, and the loss of the yarn during the lead-in process is reduced.

[0025] During the yarn drawing process, the servo motor 9 drives the screw rod 10 to rotate, and the screw nut cooperates with the guide rod 13 to convert the rotational motion of the screw rod 10 into the up and down linear motion of the guide wheel 11, guiding the yarn in the up and down directions, so that the yarn can be evenly reeled and unreeled on the yarn wheel, avoiding clutter during the yarn drawing process.

[0026] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
