Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a spindle rod used in winding machines. Background Art

[0002] The winding machine is a special equipment for the textile industry. As the last process of spinning and the first process of weaving, winding plays a "bridge" role in connecting the upper and lower processes, and therefore occupies an important position in the textile field. The winding machine presses the spun yarn tube down through the mechanical arm and puts it on the spindle rod, thereby transferring the spindle rod and the spun yarn tube to the yarn loading position and pulling out the spun yarn tube for yarn loading.

[0003] After searching, the patent announcement number is CN201720678329.2, and the name is a patent for a fully automatic winding machine bare rod spindle tube yarn support seat. The upper opening of the original automatic winding machine tube yarn support seat is gradually tightened to match the inner diameter of the bare rod spindle to adapt to the inner diameter of the spun yarn tube. When the spun yarn machine uses an aluminum rod spindle, the winder only needs to replace the original support seat to continue the original production. However, there are still many shortcomings in this patent. For example, this patent can only adapt to the inner diameter of the spun yarn tube, and it cannot achieve good compatibility with spun yarn tubes of different heights, which still causes the winder to be unable to use some models of spun yarn tubes. Utility Model Content

[0004] In view of this, the utility model aims to provide a spindle rod for a winding machine, which can adapt to different types of spun yarn tubes, so that spun yarn tubes of different heights can be pressed down to the same height to adapt to the yarn loading device of the winding machine.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A spindle bar used in a winding machine comprises a bottom bar cyclically moving on a base of the winding machine, a telescopic cylinder slidably sleeved on the bottom bar, a spring arranged inside the telescopic cylinder, and a trigger device arranged on one side of the bottom bar;

[0007] One end of the spring is connected to the inner wall of the telescopic cylinder, and the other end is connected to the bottom rod. A plurality of clamping holes are provided on the side wall of the telescopic cylinder along the axial direction of the telescopic cylinder, a through hole is provided on the side wall of the bottom rod, and a protrusion is provided inside the bottom rod through an elastic member, and the protrusion passes through the through hole to the outside of the bottom rod;

[0008] The trigger device includes a cylinder arranged at one side of the bottom rod, and an infrared sensor connected to the cylinder signal, and the output end of the cylinder is arranged corresponding to the protrusion.

[0009] Furthermore, the elastic member is an elastic sheet, which is arranged axially along the bottom rod, one end of the elastic sheet is connected to the inner wall of the bottom rod, and the other end is connected to the protrusion.

[0010] Furthermore, the bottom rod is connected to the base of the winding machine through a base, and a long rod is provided on the base. The long rod is plugged into and matched with the bottom of the bottom rod and abuts against an end of the elastic member away from the protrusion.

[0011] Furthermore, a rotating groove is opened on the base, a conveyor belt is arranged in the rotating groove, the base is connected to the conveyor belt, a plurality of positioning blocks are arranged on the inner walls on both sides of the rotating groove, and the conveyor belt is arranged between the positioning blocks on both sides of the rotating groove.

[0012] Furthermore, a limit block is provided on the bottom rod, a blind hole and a plug hole for inserting the bottom rod are provided on the base, the long rod is arranged at the bottom of the blind hole, the blind hole and the plug hole are connected, and a limit groove cooperating with the limit block is provided on the inner wall of the blind hole along the circumference of the blind hole, and the limit groove is connected to the plug hole.

[0013] Furthermore, the telescopic cylinder is provided with a plurality of elastic arc strips along the circumferential direction, and the arc strips are bent away from the telescopic cylinder.

[0014] Furthermore, a conical boss is sleeved on the bottom of the telescopic cylinder, and an end of the conical boss with a larger diameter is close to the bottom of the telescopic cylinder.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The utility model is applied to the spindle rod of the winding machine, by slidingly sleeved on the telescopic cylinder on the base, and by the clamping cooperation of the protrusion on the bottom rod and the perforation on the telescopic cylinder, when the mechanical arm on the winding machine presses the spun yarn tubes of different types on the telescopic cylinder, the protrusion can be clamped with the corresponding perforation, so that the spun yarn tube is fixed, and when the telescopic cylinder is pressed downward, the spring accumulates force, and the bottom rod and the telescopic cylinder transport the spun yarn tube to the yarn loading device of the winding machine. After the spun yarn tube is taken out, the output end of the cylinder touches the protrusion, so that the protrusion is disengaged from the clamping hole and the perforation, the spring releases energy and rebounds the telescopic cylinder to the initial height. Since the distance moved downward by the mechanical arm carrying the spun yarn tube is unchanged, the heights of spun yarn tubes of different heights after being pressed down by the mechanical arm are all the same, so it can adapt to the yarn loading device of the winding machine, and spun yarn tubes of different types can be smoothly loaded with yarn.

[0017] Furthermore, when the bottom rod is inserted into the base, the long rod can limit the position of the bottom rod so that it is not easy to fall off, and the long rod can also resist the elastic member so that the protrusion is not easy to fall off the through hole, so that the telescopic tube can be stably fixed at a suitable height.

[0018] Finally, by setting a limiting hole on the bottom rod, opening a blind hole, a plug hole and a limiting groove on the base, after the bottom rod is inserted into the blind hole, the bottom rod is rotated to engage the limiting block with the limiting groove. When the yarn loading device of the winding machine pulls out the spun yarn tube upward, the bottom rod and the base are not easily separated. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In addition, in the description of the present invention, unless otherwise clearly defined, the terms "installation", "connection", "connection", and "connector" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0033] This embodiment relates to a spindle bar used in a winding machine, an exemplary structure of which is as follows Figure 1-6 shown.

[0034] Overall, if Figure 1-2 As shown, the spindle bar used in the winding machine is installed on the base 1 of the winding machine, and includes a bottom bar 2 connected to the base 1 of the winding machine through a base 10, a telescopic cylinder 3 slidably sleeved on the bottom bar 2, a spring 4 arranged inside the telescopic cylinder 3, and a trigger device arranged on one side of the bottom bar 2;

[0035] Among them, one end of the spring 4 is fixedly connected to the middle part of the inner wall of the telescopic cylinder 3, and the other end is fixedly connected to the end of the bottom rod 2 close to the telescopic cylinder 3. In addition, along the axial direction of the telescopic cylinder 3, a plurality of clamping holes 5 are opened on the side wall of the telescopic cylinder 3, the clamping holes 5 penetrate the side wall of the telescopic cylinder 3, and a through hole 6 is opened on the side wall of the bottom rod 2. A protrusion 7 is provided inside the bottom rod 2 through an elastic member 14, and the protrusion 7 passes through the through hole 6 to the outside of the bottom rod 2. A long rod 11 is provided on the base 10, and the long rod 11 is plugged and matched with the bottom of the bottom rod 2, and abuts against the end of the elastic member 14 away from the protrusion 7.

[0036] It should be particularly noted that the mechanical arm 22 of the winding machine has a very large downward force. When the protrusion 7 is inserted into the locking hole 5, as the mechanical arm 22 continues to press downward, the protrusion 7 can be disengaged from the locking hole 5, and when the telescopic tube 3 continues to move downward, the protrusion 7 can enter the next locking hole 5, but the energy stored in the spring 4 is not enough to disengage the protrusion 7 from the locking hole 5.

[0037] like Figure 3 As shown, as an exemplary structure of the trigger device, it includes a cylinder 8 arranged on one side of the bottom rod 2, and an infrared sensor 9 connected to the cylinder 8 by signal. The output end of the cylinder 8 is arranged corresponding to the protrusion 7. Since the mechanical arm 22 of the winding machine will press the spun yarn tube down on the telescopic tube 3, the cylinder 8 is installed before the mechanical arm 22 of the winding machine, so that the output end of the cylinder 8 can touch the protrusion 7 to restore the telescopic tube 3 to its initial height, and then the mechanical arm 22 will press the spun yarn tube on the telescopic tube 3. Among them, when the protrusion 7 follows the bottom rod 2 to the infrared sensor, the infrared sensor can sense the position of the protrusion 7, and the infrared sensor transmits the signal to the cylinder 8, and the output end of the cylinder 8 moves toward the protrusion 7, and pushes the protrusion 7 to move inside the bottom rod 2, so that the protrusion 7 is disengaged from the clamping hole 5 and the perforation 6.

[0038] Preferably, the infrared sensor is connected to the motor signal that drives the transmission belt 13 on the winding machine to rotate. When the infrared sensor detects that the bottom rod 2 runs to the infrared sensor, the infrared sensor transmits a signal to the motor to stop the motor, so that the output end of the cylinder 8 has enough time to touch the protrusion 7. Then the infrared sensor transmits a signal to the motor to enable the motor to operate normally.

[0039] After this embodiment, Figure 6 As shown, the elastic member 14 is preferably an elastic sheet, which is arranged axially along the bottom rod 2, one end of the elastic sheet is connected to the inner wall of the bottom rod 2, and the other end is connected to the protrusion 7. After the telescopic cylinder 3 slides to a suitable position on the bottom rod 2, the protrusion 7 passes through the through hole 6 to the outside of the bottom rod 2 and is engaged with the clamping hole 5 on the telescopic cylinder 3, thereby fixing the height of the telescopic cylinder 3 to adapt to different types of bobbins.

[0040] In addition, the bottom bar 2 is connected to the base 1 of the winding machine through the base 10, and a long rod 11 is provided on the base 10. The long rod 11 is plugged into the bottom of the bottom bar 2 and abuts against the end of the elastic member 14 away from the protrusion 7. Among them, one end of the elastic sheet is fixedly connected to the inner wall of the bottom bar 2, and the protrusion 7 is fixed to the other end of the elastic sheet. After the long rod 11 is inserted into the bottom bar 2, the end of the long rod 11 can abut against the middle of the elastic sheet, so that the protrusion 7 is not easily separated from the clamping hole 5.

[0041] In this embodiment, a rotating groove 12 is provided on the base 1. The rotating groove 12 is annular and can be closed so that the bottom rod 2 can circulate on the base 1. A conveyor belt 13 is provided in the rotating groove 12 to connect the base 10 with the conveyor belt 13.

[0042] In addition, a plurality of positioning blocks 15 are provided on the inner walls on both sides of the rotating groove 12, and the conveyor belt 13 is arranged between the positioning blocks 15 on both sides of the rotating groove 12, so as to limit the position of the conveyor belt 13 and prevent the conveyor belt 13 from tipping over.

[0043] In addition, if Figure 5 and 7 As shown, a limit block 16 is provided on the bottom rod 2, a blind hole 17 and a plug hole 18 for inserting the bottom rod 2 are provided on the base 10, and the long rod 11 is provided at the bottom of the blind hole 17, the blind hole 17 and the plug hole 18 are connected, and a limit groove 19 cooperating with the limit block 16 is provided on the inner wall of the blind hole 17 along the circumference of the blind hole 17, and the limit groove 19 is connected with the plug hole 18. The limit block 16 on the bottom rod 2 and the ground is inserted into the blind hole 17 and the plug hole 18 together, so that the limit block 16 reaches the limit groove 19, and then the bottom rod 2 is rotated to make the limit block 16 enter the limit groove 19, and when the yarn-loading device 23 of the winding machine pulls out the spun yarn tube upward, the bottom rod 2 and the base 10 will not be separated.

[0044] In this embodiment, the telescopic tube 3 is provided with a plurality of elastic arc strips 20 along the circumferential direction, and the arc strips 20 are bent away from the telescopic tube 3. The arc strips 20 are provided on the telescopic tube, which can adapt to spun yarn tubes of different thicknesses, so that spun yarn tubes of different thicknesses can be sleeved on the telescopic tube 3 and squeeze the arc strips 20, so that the arc strips 20 accumulate force and abut against the inner wall of the spun yarn tube, thereby stabilizing the spun yarn tube on the telescopic tube 3.

[0045] In addition, a conical boss 21 is sleeved on the bottom of the telescopic cylinder 3, and the end of the conical boss 21 with a larger diameter is close to the bottom of the telescopic cylinder 3. When the spun yarn tubes of different heights are pressed downward, the bottom ends of the spun yarn tubes can be located at the same position, so that the spun yarn tubes of different heights can adapt to the yarn loading device 23 of the winder after being pressed downward.

[0046] The working process of the spindle bar applied to the winding machine of this embodiment is as follows:

[0047] First, insert the bottom rod 2 into the blind hole 17, and the limit block 16 on the bottom rod 2 is inserted into the plug hole 18 following the bottom rod 2, and the bottom rod 2 is rotated, and the limit block 16 is rotated from the plug hole 18 to the limit groove 19. Subsequently, the conveyor belt 13 on the winding machine base 1 carries the bottom rod 2 through the base 10 to move on the winding machine base 1. When the bottom rod 2 moves to the mechanical arm 22 of the winding machine, the mechanical arm 22 presses the spun yarn tube on the tube supply device 24 of the winding machine downward onto the telescopic cylinder 3. The spun yarn tube is sleeved on the telescopic cylinder 3. When the bottom of the spun yarn tube reaches the position of the conical boss 21, the arc strip 20 is compressed by the inner wall of the spun yarn tube and stores force, and supports the spun yarn tube. Then, the mechanical arm 22 drives the spun yarn tube and the telescopic cylinder 3 to move downward together, the distance between the telescopic cylinder 3 and the bottom rod 2 is reduced, and the spring 4 stores force. After the output end of the robot arm 22 moves downward to the final position, the protrusion 7 on the bottom rod 2 is inserted into the clamping hole 5 on the telescopic cylinder 3, thereby fixing the relative position between the telescopic cylinder 3 and the bottom rod 2, that is, fixing the height of the spun yarn tube. Finally, when the conveyor belt 13 carries the spun yarn tube through the bottom rod 2 and the telescopic cylinder 3 to the yarn loading device 23 of the winding machine, the yarn loading device 23 takes the spun yarn tube on the telescopic cylinder 3 upward. After the spun yarn tube is taken away, the conveyor belt 13 continues to carry the bottom rod 2 and the telescopic cylinder 3 to the trigger device. When the infrared sensor detects the bottom rod 2, the infrared sensor transmits a signal to the cylinder 8. The output end of the cylinder 8 extends and touches the protrusion 7, so that the protrusion 7 moves toward the inside of the bottom rod 2, and finally the protrusion 7 is disconnected from the clamping hole 5 on the telescopic cylinder 3. The spring 4 releases energy, and the spring 4 drives the telescopic cylinder 3 to return to the initial height. The above process is repeated, so that when the spun yarn tube is prevented from being placed on the telescopic cylinder 3, the height of the spun yarn tube does not need to be limited.

[0048] It should be noted that the mechanical arm 22, the tube supply device 24 and the yarn loading device 23 in this embodiment are all supporting mechanisms of the existing winding machine, so the specific structures of the three are not repeated here.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
