Abstract
Description
Technical Field
[0001] This utility model relates to the field of napping machine technology, specifically a high-speed napping machine. Background Technology
[0002] A yarn napping machine is a device integrated into an automatic winding or sizing machine in textile processing. By applying a wax layer to the yarn surface during the winding or sizing process, it can reduce yarn surface fuzz, lower the coefficient of friction, and improve the smoothness and abrasion resistance of the yarn surface, thereby optimizing the subsequent weaving or knitting performance of the yarn. Existing yarn napping machines mostly consist of a housing, spindles, a grooved cylinder, a motor, and a wax disc. The grooved cylinder and motor are located in the upper middle part of the housing. The motor drives the grooved cylinder to rotate, and the spindles are rotated and connected above the grooved cylinder. The wax disc is located on the upper right side of the housing. In use, the yarn bobbin with the yarn wound is placed on the rack on the right side of the housing. Paraffin wax is inserted into the wax disc, and the yarn passes between the paraffin wax and the wax disc. Then, the yarn is attached to the outer surface of the guide frame, wrapped several times around the surface of the empty yarn bobbin, and then the empty yarn bobbin is secured between two spindles, ensuring the empty yarn bobbin is in contact with the outer surface of the grooved cylinder. In traditional yarn-winding machines, the yarn gets stuck inside the groove of the trough. The motor drives the trough to rotate, and the empty yarn bobbin rotates accordingly. The yarn is wound around the surface of the empty yarn bobbin. The rotating trough guides the yarn to move back and forth, allowing the yarn to be evenly wound around the surface of the empty yarn bobbin. After long-term operation, impurities and yarn ends will get stuck between the end face of the trough and the mounting post, affecting the rotation of the trough and also affecting the transmission and heat dissipation of the motor. Regular cleaning is required. During cleaning, the machine cover needs to be opened, and then the bolts under the front support block of the trough need to be loosened first, then the bolts under the rear support block of the trough need to be loosened, and then the bolts fixing the motor need to be loosened so that the motor, mounting post and trough can be deflected to the right. Finally, the fixing bolts of the trough itself need to be loosened before the trough can be removed, so as to clean the impurities and yarn ends wrapped around the surface of the mounting post. The whole process requires disassembling and assembling a large number of bolts, which is very inconvenient. Therefore, we propose a high-speed yarn-winding machine. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a high-speed de-firing machine that can quickly disassemble and assemble the groove cylinder, which facilitates the cleaning of impurities and yarn ends on the surface of the mounting column and can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-speed napping machine, including a napping machine frame, a napping machine housing on the upper front side of the napping machine frame, a base on the upper end of the napping machine housing, a rotatable rotating seat on the upper end of the base, an installation column rotatably connected in the middle of the interior of the rotating seat, and also including a disassembly and assembly mechanism.

The lead screw is rotatably connected to the middle of the lower inner end of the rotating seat. The limiting block is slidably connected to the front side of the lower inner end of the rotating seat. The middle of the inner end of the limiting block is threadedly connected to the front end of the outer surface of the lead screw. The limiting posts are respectively set on the left and right sides of the lower front end of the rotating seat. A support block is provided between the two limiting posts. The front end of the outer surface of the mounting post is inserted into the middle of the upper inner end of the support block. The lower inner end of the support block is rotatably connected to the front side of the outer surface of the limiting block. This provides a basis for disassembly and assembly for cleaning impurities and yarn ends on the surface of the mounting post. The limiting assembly is set between the base and the rotating seat, which enables quick disassembly and assembly of the groove cylinder, facilitating the cleaning of impurities and yarn ends on the surface of the mounting post.
[0005] Furthermore, the limiting component includes a connecting shaft, a plug, and a knob. The connecting shaft is located at the middle of the upper rear side of the base. The middle of the inner rear side of the rotating seat is rotatably connected to the outer surface of the connecting shaft. The plug is opened in the middle of the inner side of the connecting shaft. The plug is slidably connected to the rear side of the inner wall of the rotating seat. The middle of the inner side of the plug is threadedly connected to the rear end of the outer surface of the lead screw. The rear side of the outer surface of the plug is inserted into the inner wall of the plug hole. The knob is located in the middle of the outer surface of the lead screw, providing a basis for the rotation and limiting of the rotating seat.
[0006] Furthermore, the disassembly and assembly mechanism also includes a limiting groove and a limiting hook. The limiting groove is located at the front center of the base, and the limiting hook is located at the lower center of the support block. The limiting groove and the limiting hook are installed together to further improve the fixing effect of the support block.
[0007] Furthermore, the disassembly and assembly mechanism also includes a groove and fixing bolts. The groove is inserted into the middle of the outer surface of the mounting column, and the fixing bolts are threaded to the front and rear ends on the right side inside the groove. The left ends of the fixing bolts are all in contact with the right end of the mounting column, providing a basis for the disassembly and assembly of the groove itself.
[0008] Furthermore, it also includes a motor, which is located on the upper right side of the rotating base. The input end of the motor is electrically connected to the output end of the microcontroller, and the front end of the motor's output shaft is fixedly connected to the rear end of the mounting column to provide a driving effect for the rotation of the groove cylinder.
[0009] Furthermore, a tensioning frame is rotatably connected to the middle of the upper left side of the yarn rewinding frame, and spindles are rotatably connected to the right ends of the front and rear side walls of the tensioning frame, providing a basis for fixing and pressing the yarn bobbin.
[0010] Furthermore, a placement rack is provided in the middle of the lower right side of the napping machine housing, a pressure plate is provided in the middle of the upper right side of the napping machine housing, a wax plate is provided in the middle of the upper end of the napping machine housing, a yarn detection sensor is provided at the rear of the upper right side of the napping machine housing, the yarn detection sensor is bidirectionally electrically connected to the microcontroller, and a wire frame is provided in the upper right side of the napping machine housing to provide a basis for waxing and guiding the yarn.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-speed napping machine has the following advantages: Turning the knob drives the lead screw, which in turn moves the limit block and the insert. When the insert moves forward, the rotating seat loses its limit and can deflect to the right. When the limit block moves forward, the support block loses its limit effect, can separate from the mounting column and deflect, which facilitates the cleaning of impurities and the removal and placement of the groove cylinder. The entire process does not require opening the deburring machine casing or disassembling a large number of bolts to clean debris and disassemble the groove cylinder, which is very convenient.

[0016] Please see Figure 1-5This embodiment provides a technical solution: a high-speed de-hairing machine, including a de-hairing machine frame 1, a de-hairing machine housing 9 on the upper front side of the de-hairing machine frame 1, a base 2 on the upper end of the de-hairing machine housing 9, a rotatable rotating seat 3 on the upper end of the base 2, a mounting column 4 rotatably connected in the middle of the interior of the rotating seat 3, the mounting column 4 being a hexagonal prism, and also includes a microcontroller 15, the microcontroller 15 being located on the upper right rear side of the de-hairing machine housing 9, the input terminal of the microcontroller 15 being electrically connected to an external power supply to provide control for the de-hairing operation, and also includes a disassembly and assembly mechanism 5; The disassembly and assembly mechanism 5 includes a lead screw 51, a limiting block 52, a limiting post 53, a support block 54, and a limiting component 55. The lead screw 51 is rotatably connected to the middle of the lower inner end of the rotating seat 3. The limiting block 52 is slidably connected to the front side of the lower inner end of the rotating seat 3.

The limiting posts 53 are respectively set on the left and right sides of the lower front end of the rotating seat 3. A support block 54 is provided between the two limiting posts 53. The front end of the outer surface of the mounting post 4 is inserted into the middle of the upper inner end of the support block 54. The lower inner end of the support block 54 is rotatably connected to the front side of the outer surface of the limiting block 52, providing a disassembly and assembly basis for cleaning impurities and yarn ends on the surface of the mounting post 4. The limiting component 55 is set between the base 2 and the rotating seat 3, which can quickly disassemble and assemble the groove cylinder 58, facilitating the cleaning of impurities and yarn ends on the surface of the mounting post 4.
[0017] The limiting assembly 55 includes a connecting shaft 551, a pin 553, and a knob 554. The connecting shaft 551 is located at the middle of the upper rear side of the base 2. The middle of the inner rear side of the rotating seat 3 is rotatably connected to the outer surface of the connecting shaft 551. The insertion hole 552 is opened in the middle of the inner side of the connecting shaft 551. The pin 553 is slidably connected to the rear side of the inner wall of the rotating seat 3. The middle of the inner side of the pin 553 is threaded to the rear end of the outer surface of the lead screw 51.

The inner wall of 552 is inserted, and the knob 554 is set in the middle of the outer surface of the lead screw 51. Corrugated tubes can be added between the limiting block 52 and the insert 553 and the inner wall of the rotating seat 3. The corrugated tubes are all sleeved on the outer surface of the lead screw 51. The corrugated tubes can contract and expand as the limiting block 52 and the insert 553 move, providing protection for the lead screw 51. A baffle is provided on the right side of the upper rear end of the base 2. The left end of the baffle on the right end of the rotating seat 3 is attached to it, providing a basis for the rotation and limiting of the rotating seat 3. The disassembly and assembly mechanism 5 also includes a limiting groove 56 and a limiting hook 57. The limiting groove 56 is opened at the front middle of the base 2, and the limiting hook 57 is set at the lower middle of the support block 54. The limiting groove 56 and the limiting hook 57 are installed together. The inner wall of the limiting hook 57 presses against the inner wall of the limiting groove 56, so that the inner wall of the limiting hook 57 can be tightly attached to the inner wall of the limiting groove 56, further improving the fixing effect of the support block 54. The disassembly and assembly mechanism 5 also includes a slotted cylinder 58 and fixing bolts 59. The slotted cylinder 58 is inserted into the middle of the outer surface of the mounting column 4.

A tensioning frame 7 is rotatably connected to the middle of the upper left side of the napping machine frame 1. The tensioning frame 7 is a common tensioning structure in existing napping machines. A torsion spring is provided between the inner left side of the tensioning frame 7 and the middle of the upper left side of the napping machine frame 1. The torsion spring can provide a downward force for the tensioning frame 7, so that the yarn bobbin can be tightly attached to the outer surface of the grooved cylinder 58. Spindles 8 are rotatably connected to the right ends of the front and rear side walls of the tensioning frame 7. Empty yarn bobbins can be stuck between two spindles 8, providing a basis for fixing and pressing the yarn bobbin. A placement rack 10 is provided in the middle of the lower right side of the napping machine housing 9. The placement rack 10 is used to place yarn with yarn attached. The upper right side of the yarn rewinding machine housing 9 is equipped with a pressure plate 11, which can press the yarn tightly. The upper middle part of the yarn rewinding machine housing 9 is equipped with a wax plate 12, and a paraffin block can be inserted into the upper part of the wax plate 12. The yarn detection sensor 13 is located at the upper rear right side of the yarn rewinding machine housing 9. The yarn detection sensor 13 is bidirectionally electrically connected to the microcontroller 15. The yarn detection sensor 13 monitors the yarn running status through photoelectric detection principle. When the yarn stops or breaks, it can trigger the automatic control system to stop the equipment operation. The upper right side of the yarn rewinding machine housing 9 is equipped with a wire guide 14, which provides a basis for waxing and guiding the yarn.
[0018] The working principle of the high-speed napping machine provided by this utility model is as follows: When using the high-speed napping machine, first, the yarn bobbin wrapped with yarn is placed on the upper end of the placement frame 10. The yarn is first passed through the pressure plate 11, then through the notch on the limiting plate, and then through the upper ends of the two wax discs 12 in sequence. Then, it is pushed upwards through the guide wheel and attached to the surface of the guide frame 14. Then, the yarn is wound around the surface of the empty yarn bobbin. After several turns, the empty yarn bobbin is clamped between the two spindles 8. The tension frame 7 is loosened so that the outer surface of the empty yarn bobbin is in contact with the outer surface of the groove cylinder 58. At the same time, the yarn is clamped inside the groove on the surface of the groove cylinder 58. Finally, the paraffin block is inserted into the upper end of the wax disc 12. The paraffin block and the wax disc 12 form a clamping effect on the yarn. The microcontroller 15 controls the motor 6 to run, and the output shaft of the motor 6 drives... As the mounting post 4 rotates, the grooved cylinder 58 also rotates. The friction between the outer surface of the grooved cylinder 58 and the surface of the empty yarn bobbin causes the empty yarn bobbin to rotate as well. Simultaneously, as the grooved cylinder 58 rotates, the grooves on its surface cooperate to allow the yarn to move back and forth, ensuring it is evenly wound around the surface of the empty yarn bobbin. When the yarn passes the wax disc 12, the paraffin blocks on the wax disc 12 contact the yarn, creating a waxing effect. After prolonged use, impurities and yarn ends may become stuck between the end face of the grooved cylinder 58 and the outer surface of the mounting post 4, requiring cleaning. Rotating the knob 554 forward causes the lead screw 51 to rotate, moving the limiting block 52 forward. The inner wall of the limiting hook 57 separates from the inner wall of the limiting groove 56 until the front end of the limiting block 52... After the distance between the front ends of the limiting posts 53 is greater than the thickness of the support block 54, the support block 54 is moved to the right, so that the support block 54 is completely separated from the limiting posts 53. At this time, the inner ring of the bearing at the upper end of the support block 54 is also separated from the front end of the outer surface of the mounting post 4. Since the front end of the outer surface of the limiting block 52 is cylindrical, as the support block 54 moves to the right, after the support block 54 is separated from the limiting posts 53 and the mounting post 4, it can deflect left and right. At the same time, as the lead screw 51 rotates, the insertion post 553 also moves forward. When the limiting block 52 moves into place, the insertion post 553 is also completely separated from the insertion hole 552. The rotating seat 3 loses its limiting effect and can deflect to the right, which is convenient for subsequent cleaning work. At this time, the front end of the mounting post 4 loses its limiting and supporting effect, and the groove can be quickly opened. Clean the impurities and yarn ends from the front end of the cylinder 58, then reverse the fixing bolt 59. The fixing bolt 59 separates from the right end of the mounting post 4, and the grooved cylinder 58 loses its limiting effect. The grooved cylinder 58 can then be pulled away from the outer surface of the mounting post 4. Then clean the impurities and yarn ends from the rear end of the grooved cylinder 58. After cleaning, insert the grooved cylinder 58 back into the outer surface of the mounting post 4, then rotate the fixing bolt 59 clockwise to fix the grooved cylinder 58. Then rotate the rotating seat 3 back to its original position. The baffle on the right side of the upper rear end of the base 2 can ensure that the rotating seat 3 can accurately return to its original position. Then move the support block 54 to the right so that the front end of the outer surface of the mounting post 4 is inserted into the inner ring of the bearing at the upper end of the support block 54. The limiting key at the upper end of the inner wall of the bearing inner ring is inserted into the keyway above the front end of the outer surface of the mounting post 4. At the same time,The lower inner end of the support block 54 is also inserted into the outer surface of the corresponding limiting post 53. The reverse knob 554 drives the lead screw 51 to rotate, causing the insertion post 553 to move backward and insert into the insertion hole 552. The rear end of the rotating seat 3 is limited, and the limiting block 52 also moves backward. As the limiting block 52 moves, it presses the support block 54 backward, making the support block 54 tightly against the front end of the rotating seat 3. Simultaneously, as the support block 54 moves backward, the inner wall of the limiting hook 57 presses against the inner wall of the limiting groove 56, making the inner wall of the limiting hook 57 tightly against the inner wall of the limiting groove 56, further limiting the front end of the rotating seat 3. The entire process does not require opening the roughening machine housing 9 or disassembling a large number of bolts, making it very convenient.
[0019] It is worth noting that the microcontroller 15 disclosed in the above embodiments is an STM32H743VIT6 microcontroller, the motor 6 is a 2BLD10-24GN-20S motor, and the yarn detection sensor 13 is a KJT-DU17 yarn detection sensor. The microcontroller 15 controls the operation of the motor 6 and the yarn detection sensor 13 using methods commonly used in the prior art.
