[0041] Embodiment 1:

[0042] Please refer to Figure 1-Figure 7 The present embodiment is a blowing and suction type automatic yarn combining and plying yarn supply device 100, which includes a rotating support module 1, a plurality of spindle support modules 2 arranged around the rotating support module 1, a thread end blowing module 3 arranged corresponding to each spindle support module 2 and blowing around the yarn roll 20 on the spindle support module 2, and a thread end suction yarn gathering module 4 located above the rotating support module 1 and collecting the thread ends blown out by the thread end blowing module 3 and blowing them upwards.

[0043] The rotary support module 1 comprises a first driving member 11 and a rotary support 12 driven by the first driving member 11 to perform rotary motion.

[0044] In this embodiment, the outer periphery of the rotating bracket 12 has a plurality of support rods 121 which are distributed at equal angles and extend radially horizontally, and the spindle support module 2 is arranged at the free end of the support rods 121 .

[0045] In other embodiments, the rotating bracket 12 may also be designed as a disc structure, on which a plurality of installation stations are arranged at equal angles, and a spindle supporting module 2 is arranged at each installation station.

[0046] The spindle support module 2 includes a second driving member 21 fixed on the rotating bracket 12, a support cylinder seat 22 driven by the second driving member 21 to move up and down, and a spindle seat assembly 23 fixed on the top of the support cylinder seat 22. The second driving member 21 drives the support cylinder seat 22 to move up and down, thereby adjusting the height of the spindle seat assembly 23, so as to realize automatic adjustment of the size of the unwinding air ring of the yarn roll 20 to be suitable for various yarns of different materials and thicknesses. In order to monitor the height position of the spindle seat assembly 23 moving up and down, a distance sensor 24 for monitoring the up and down movement position of the spindle seat assembly 23 is also provided on the rotating bracket 12.

[0047] After the yarn roll 20 is placed on the spindle support module 2, if the position of the yarn roll 20 is not locked, it is easy to jump up during the withdrawal process, causing the yarn to be instantly subjected to excessive force and break. In order to solve this technical problem, the present embodiment optimizes the structure of the spindle seat assembly 23. Specifically, the spindle seat assembly 23 includes a contoured inner support cone 231 fixed to the top of the support cylinder seat 22 and a locking assembly 232 arranged in the contoured inner support cone 231. The contoured inner support cone 231 is provided with a plurality of first channels 2311 distributed in an annular manner and extending radially outward from the center of the contoured inner support cone 231, and a second channel 2312 connected to the first channel 2311 and extending axially upward.

[0048] In this embodiment, the locking assembly 232 includes a plurality of first balls 2321 arranged in the first channel 2311, a second ball 2322 movably arranged in the second channel 2312, a magnet 2323 located above the second ball 2322 and adsorbing the second ball 2322, a spring 2324 fixedly connected to the magnet 2323 at the bottom, and an unlocking rod 2325 fixedly connected to the top of the spring 2324 and extending out of the second channel 2312 at the top.

[0049] In the initial state, the unlocking rod 2325 is straightened to a high position, and under the joint action of the spring 2324, the magnet 2323 is driven to attract the second ball 2322 and move it to a high position, and the first ball 2321 in the first channel 2311 loses the radial outward thrust constraint; when the yarn roll 20 is placed on the contoured inner support cone 231, the cone 30 inside the yarn roll 20 sits on the contoured inner support cone 231, and under the action of the gravity of the yarn roll 20, the unlocking rod 2325 is pressed downward by the cone 30, thereby compressing the spring The spring 2324, together with the magnet 2323 and the second ball 2322, is pressed downward to a low position. Under the squeezing action of the second ball 2322, the first ball 2321 in the first channel 2311 is pushed outward, thereby holding the inner wall of the cone cylinder 30 to achieve rotational locking of the cone cylinder 30; when all the yarn on the yarn roll 20 is pulled away and the next new yarn roll needs to be replaced, the operator takes out the empty cone cylinder and then pulls the unlocking rod 2325 upward to drive the second ball 2322 to a high position to achieve unlocking.

[0050] In the locking assembly 232 , the provision of the spring 2324 can eliminate the risk of the unlocking rod 2325 being unable to be pressed down into place due to manufacturing errors of the cone cylinder 30 , thereby improving the locking reliability of the locking assembly 232 .

[0051] The thread end blowing module 3 includes a third driving member 31, a turntable 32 rotatably arranged on the outer periphery of the support cylinder seat 22 and driven to rotate by the third driving member 31, and an air nozzle 33 fixed on the turntable 32 and aimed at the yarn roll 20 on the spindle seat assembly 23 to blow air. The air nozzle 33 is driven by the third driving member 31 to rotate around the yarn roll 20, and the airflow ejected by the air nozzle 33 is used to find the thread end of the outer circle of the yarn roll 20, thereby realizing the thread end automatic finding function.

[0052] In other embodiments, the third driving member 31 may be directly fixed to the support cylinder seat 22, thereby eliminating the need for the third driving member 31. However, this may cause the center of gravity of the spindle support module 2 to deviate from the axis of the support cylinder seat 22, resulting in eccentricity, which may reduce the service life of the spindle support module 2. In order to solve the eccentricity problem, a support plate may be fixedly mounted on the support cylinder seat 22, the third driving member 31 may be disposed on the support plate, and then a counterweight may be disposed on the support plate to ensure that the support plate is subjected to balanced force, thereby solving the eccentricity problem of the spindle support module 2.

[0053] In order to achieve the airflow of set pressure from the inside of the air nozzle 33 and prevent the hose from being entangled when the turntable 32 rotates, the present embodiment optimizes the structure of the connection structure between the turntable 32 and the spindle seat assembly 23. Specifically, a support shaft 221 is provided at the top of the support cylinder seat 22, and a bottom section of the support shaft 221 extends into the support cylinder seat 22. The turntable 32 is rotatably arranged on the support shaft 221 through a bearing 34. A first air passage 321 connected to the air nozzle 33 is provided in the turntable 32, and an annular air chamber 35 connected to the first air passage 321 is formed between the inner hole of the turntable 32 and the outer peripheral surface of the support shaft 221. A second air passage 2211 connected to the annular air chamber 35 is provided in the support shaft 221, and a third air passage 222 connected to the second air passage 2211 is provided in the support cylinder seat 22. The third air passage 222 is connected to an external air source; a sliding sealing pad 36 for sealing the annular air chamber 35 is provided at the interface between the turntable 32 and the support cylinder seat 22. The external air source enters from the support cylinder seat 22, passes through the third air channel 222 and the second air channel 2211 in sequence, and then enters the annular air chamber 35. No matter how the turntable 32 rotates relative to the support shaft 221, the annular air chamber 35 always remains connected with the first air channel 321, so that the first air channel 321 can always maintain air pressure, thereby ensuring that the air nozzle 33 can blow out an airflow of set pressure during the rotation process.

[0054] Since the turntable 32 needs to rotate on one hand and move up and down with the support cylinder seat 22 on the other hand, in order to realize the rotation drive of the turntable 32 by the third driving member 31 without affecting the lifting movement of the turntable 32, this embodiment optimizes the transmission structure of the third driving member 31 driving the turntable 32. Specifically, the rotating shaft of the third driving member 31 is horizontally arranged, and a magnet rotor 37 is arranged at its rotating end, and a plurality of magnetic blocks 38 distributed in an annular manner and cooperating with the magnet rotor 37 are arranged on the lower surface of the turntable 32.

[0055] In order to ensure that the magnet rotor 37 can reliably and stably cooperate with the magnetic block 38 for transmission, the thread blowing module 3 also includes a fourth driving member 39 that drives the third driving member 31 to move up and down. The fourth driving member 39 is fixed on the rotating bracket 12. The third driving member 31 is driven up and down by the fourth driving member 39 to cooperate with the height change of the turntable 32 when the spindle seat assembly 23 is adjusted in height.

[0056] The yarn suction head yarn gathering module 4 includes a yarn gathering shaft ring 41 and a plurality of yarn suction tubes 42 arranged around the outer periphery of the yarn gathering shaft ring 41 and arranged corresponding to the spindle support module 2. A ceramic ring 43 is installed in the yarn gathering shaft ring 41, and a yarn gathering opening 431 is formed inside the ceramic ring 43, which passes through from top to bottom. One end of the yarn suction tube 42 is downwardly aligned with the spindle seat assembly 23 and the other end is connected to the yarn gathering opening 431. There is an upward airflow in the yarn gathering opening 431 to generate negative pressure in the yarn suction tube 42 to absorb the yarn ends. When automatically finding the thread end, one end of the yarn suction tube 42 is located at a set height position directly above the spindle seat assembly 23, and the air nozzle 33 rotates around the yarn reel 20 on the spindle seat assembly 23 at a set speed. When it rotates to the position of the thread end, the thread end will be blown upward, and under the suction force of the yarn suction tube 42, the thread end will be sucked into the yarn suction tube 42, and multiple thread ends will be gathered at the yarn gathering opening 431, realizing automatic thread end finding and automatic yarn gathering operations. Subsequent operators or automatic thread clamping devices can extract the gathered thread ends at the output end of the yarn gathering shaft ring 41 for subsequent threading operations. Compared with the original need for operators to find thread ends, thread yarn, and hang yarn for each yarn reel, the workload of operators is greatly reduced, and the production efficiency of the yarn combining process is improved.

[0057] In order to monitor whether there is yarn sucked in the yarn suction tube 42, a yarn detection sensor 44 is provided on the yarn suction tube 42. The yarn detection sensor 44 is arranged near the yarn suction port of the yarn suction tube 42. In order to realize the flexible setting function of the number of parallel yarns, the yarn suction tube 42 is also provided with an electromagnetic control valve 45 for controlling the closing or conduction of the internal pipeline of the yarn suction tube 42. When the corresponding yarn suction tube 42 needs to start the yarn suction function, the electromagnetic control valve 45 is opened, otherwise it is in a closed state.

[0058] In order to generate negative pressure in the yarn suction tube 42 and generate an airflow from bottom to top in the yarn gathering shaft ring 41. The present embodiment also includes a central air guide column 5. The bottom end of the central air guide column 5 is fixedly arranged on the rotating bracket 12 and is located at the rotation center of the rotating bracket 12, and the top end is rotatably connected to the yarn gathering shaft ring 41. A fourth air channel 51 connected to the yarn gathering port 431 and a plurality of fifth air channels 52 distributed around the axis and corresponding to the spindle seat assembly 23 are arranged inside the central air guide column 5. The fifth air channel 52 extends axially upward from the bottom of the central air guide column 5 to a set length, one end of which is provided with an air inlet, and the other end is connected to the third air channel 222 in the support tube seat 22 through a hose 53. The fourth air channel 51 and the plurality of fifth air channels 52 each independently control the conduction and blocking of the air pressure inside them.

[0059] In the present embodiment, five groups of spindle support modules 2 are provided, which can hold up to five rolls of yarn. In other embodiments, other numbers of spindle support modules 2 can be provided as required, and a corresponding number of yarn suction tubes 42 can be configured.

[0060] The overall working process of a blowing and suction type automatic doubling and plying yarn supply device 100 of this embodiment includes the following steps:

[0061] (1) The operator places a corresponding number of yarn rolls 20 on the spindle support module 2 according to the number of single yarns required for doubling, specifically on the contoured inner support cone 231 of the spindle seat assembly 23, and locks and fixes the yarn rolls 20 through the locking assembly 232;

[0062] (2) The unwinding suction port angle is set according to the material and thickness of the yarn, and the first driving member 11 adjusts the rotating bracket 12 to rotate according to the unwinding suction port angle, so that the relative position of each spindle support module 2 and the upper yarn suction tube 42 meets the above unwinding suction port angle requirement, thereby realizing automatic adjustment and correction of the unwinding suction port angle;

[0063] (3) The size of the unwinding balloon is set according to the material and thickness of the yarn, and the second driving member 21 adjusts the upper and lower heights of the spindle seat assembly 23 according to the size of the unwinding balloon, so that the upper and lower heights of the spindle seat assembly 23 and the upper yarn suction tube 42 meet the requirements, ensuring that after the yarn roll 20 is placed on the spindle seat assembly 23, the size of the unwinding balloon when the yarn is sucked into the yarn suction tube 42 and unwound is within the set range;

[0064] (4) The fourth driving member 39 adjusts the height of the third driving member 31 accordingly to ensure reliable matching and transmission between the magnet rotor 37 and the magnetic block 38;

[0065] (5) All air passages in the central air guide column 5 are ventilated, and the third driving member 31 drives the air nozzle 33 to start rotating. The rotation direction of the air nozzle 33 is consistent with the unwinding direction of the yarn. The air nozzle 33 starts to search for the thread end around the outer peripheral surface of the yarn roll 20. When the thread end 40 is found, the thread end 40 is blown upward for unwinding. As the air nozzle 33 continues to blow and rotate, the length of the thread end 40 blown out becomes longer and longer. When the length of the thread end 40 blown out enters the suction range of the yarn suction tube 42, the thread end 40 is sucked into the yarn suction tube 42 and is continuously sucked. It continues to enter the yarn gathering port 431 and is then output from the upper part of the yarn gathering port 431. When the yarn detection sensor 44 in one of the yarn suction tubes 42 detects that yarn has entered, the air nozzle 33 in the corresponding thread end blowing module 3 stops rotating and stops blowing. When yarn has entered each of the yarn suction tubes 42 that are turned on for yarn suction, the automatic thread end finding and automatic thread end gathering and hanging of all the yarn winding ends are completed. The gathered thread ends are moved upward together and then passed through the concentrated tension system 200 and then wound on the winding drum 300 to complete the winding and forming.

[0066] The blowing and suction type automatic yarn combining and plying yarn feeding device 100 of the present embodiment meets the needs of users for automated production and reduces the intensity of workers' repetitive labor. Some process steps are fully automated, which minimizes manual work. The unwinding suction port angle automatic correction and unwinding air circle size automatic adjustable function are adopted. By controlling the distance and angle between the feeding yarn and the suction port, the yarn counts of different materials and thicknesses are adapted, and the functionality is greatly compatible and expanded. The spindle seat assembly adopts a press-locking profiling seat, and each feeding yarn roll is fixed more conveniently. There will be no problem of flying out during the processing process due to the unreliable fixation of the inner tube of the feeding yarn roll, or the operator's hand being injured due to the insertion and pulling of the yarn tube too tightly. Since there will be no unnecessary shutdown due to the time required for manual yarn hanging operations, the saved time will be returned to automated continuous production, thereby greatly improving production efficiency.

[0067] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, all of which fall within the protection scope of the present invention.
