[0033] To further illustrate the technical means and effects adopted by this application to achieve the intended inventive purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of an automatic knotting machine proposed according to this application. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0035] The specific solution of an automatic knotting machine provided in this application is described below with reference to the accompanying drawings.
[0036] Please combine Figures 1-3The first embodiment of this application provides an automatic knotting machine for knotting yarn packages, including: a frame 1 and a conveying component 2, a rotating component 3 and a knotting component 4 disposed on the frame 1. The rotating component 3 and the conveying component 2 are arranged sequentially in a vertical direction, and the knotting component 4 is close to and disposed on one side of the rotating component 3 and the conveying component 2.
[0037] The conveying component 2 includes a sensing unit and a recycling device 20, which is used to drive the yarn bobbin close to the rotating component 3, and drive the yarn bobbin to the knotting component 4 through the rotating component 3, and convey the excess tail yarn after knotting to the recycling device 20.
[0038] The knotting assembly 4 includes at least two drive mechanisms 40 and a knotter 41 and a shearing part 42 respectively connected to the drive mechanisms 40, with the knotter 41 and the shearing part 42 being arranged correspondingly.
[0039] The rotating assembly 3 includes a guide part 30, which drives the yarn bobbin to rotate and guide it to the knotter 41. The knotter 41 is in close contact with the guide part 30 through the drive mechanism 40 to knot the yarn bobbin and cuts off the excess tail yarn after knotting through the shearing part 42.
[0040] To better illustrate, in the actual application of yarn cones, after the winding machine completes the winding of the yarn and reaches a full cone state, the yarn cone is sent to the yarn transport trolley via a conveyor belt. However, since the tail yarn at the end of the yarn cone is not fixed, the yarn of the yarn cone may scatter, entangle, or even become entangled on the yarn column of the dyeing vat during transportation and subsequent yarn dyeing processes. This not only affects production efficiency but may also lead to a decline in yarn quality, causing inconvenience to subsequent textile work. Therefore, the automatic knotting machine proposed in this application is used to knot and fix the yarn cone and collect excess tail yarn to avoid scattering and entanglement during transportation and subsequent processes.
[0041] As an optional implementation, the sensing unit includes photoelectric sensors, capacitive sensors, ultrasonic sensors, and proximity switches, etc.; the recycling device 20 includes a collection box for recycling tail yarn, an automatic winding machine, or a packaging machine, etc.; preferably, in this embodiment, the sensing unit is a photoelectric sensor, which detects the presence of yarn bobbins by emitting and receiving light. When the yarn bobbin blocks the light, the sensor outputs a corresponding signal to determine that the yarn bobbin has entered the conveying assembly 2. The photoelectric sensor has a fast response speed and high accuracy, and is suitable for high-speed production lines; the recycling device 20 is a collection box, wherein the tail yarn refers to the remaining yarn after knotting during the textile process. It is usually too short to be used in production, so the tail yarn is collected in the collection box for subsequent reuse.
[0042] Furthermore, the drive mechanism 40 consists of a first ejector cylinder 400 and a second ejector cylinder 401, which are respectively connected to the knotter 41 and the shearing part 42. Optionally, the shearing part 42 includes tools such as scissors or cutters for cutting yarn, which can be replaced or adjusted according to actual needs to adapt to different types of yarn packages and different cutting requirements. That is, the knotter 41 and the shearing part 42 are driven by the first ejector cylinder 400 and the second ejector cylinder 401, respectively. The gas in the cylinder is discharged through piston movement to achieve drive, and the yarn packages are knotted and fixed in sequence to ensure that the yarn will not unravel in subsequent processing. The knotted yarn is then cut to complete the continuous processing of the yarn packages.
[0043] Please combine Figures 1-2 and Figures 4-5 Furthermore, the conveying assembly 2 also includes a yarn feeding slide 21 and a transverse mechanism 22. The transverse mechanism 22 is provided with a rotating bowl 220, a first support 221, a second support 222 and a first drive motor 223. The first drive motor 223 is arranged opposite to the knotting assembly 4, and the rotating bowl 220 is arranged between the first drive motor 223 and the knotting assembly 4. The first support 221 and the second support 222 are sleeved to form a fixing post 224 arranged along the center of the rotating bowl 220. The sensing unit is arranged in the rotating bowl 220. The yarn bobbin enters the rotating bowl 220 through the yarn feeding slide 21. When the sensing unit detects the yarn bobbin, it fixes the yarn bobbin through the fixing post 224 and conveys the yarn bobbin to the corresponding working position of the rotary assembly 3.
[0044] As explained, the second support 222 is disposed within the internal space of the first support 221, forming a nested relationship between the two, constituting a fixing column 224 to fix the yarn package, ensuring that the yarn package remains stable during the subsequent knotting process and does not slip or tilt, thereby improving the overall operating efficiency of the equipment and the performance of the yarn package. Specifically, after the automatic knotting machine is started, the opening of the flip bowl 220 faces the yarn infeed slide 21, and the yarn package slides into the flip bowl 220 through the yarn infeed slide 21. After the sensing unit detects the presence of the yarn package, the fixing column 224 works to fix the yarn package inside the flip bowl 220, and the first drive motor 223 rotates the flip bowl 220 to the working position corresponding to the rotary assembly 3.
[0045] Furthermore, the conveying assembly 2 also includes a yarn suction mechanism 23 located near the tilting bowl 220. The yarn suction mechanism 23 includes a yarn suction nozzle 230, a lifting cylinder 231, and a suction fan 232. The yarn suction nozzle 230 is located near the yarn feeding slide 21 and connected to the lifting cylinder 231. The suction fan 232 is located opposite the transverse movement mechanism 22 and near the recycling device 20. The yarn suction mechanism 23 is used to fix the tail yarn of the yarn package and automatically collect and knot the remaining tail yarn after it has been cut off. That is, the yarn suction nozzle 230 sucks up the tail yarn, and the other end is driven to rotate to the knotter 41 through the guide part 30 to assist the knotter 41 in better knotting. After completion, the remaining tail yarn that has been cut off is driven by the lifting cylinder 231 through the yarn suction nozzle 230 and driven by the suction fan 232 to collect the tail yarn into the recycling device 20.
[0046] Furthermore, the rotary assembly 3 also includes a rotating arm 31 and a second drive motor 32 connected in sequence to the guide portion 30. The second drive motor 32 drives the rotating arm 31 to rotate the guide portion 30. It can be noted that a pneumatic slip ring is provided between the second drive motor 32 and the rotating arm 31, that is, the second drive motor 32 provides driving force to the pneumatic slip ring, and then drives the rotating arm 31 to rotate. An ejection cylinder is provided between the rotating arm 31 and the guide portion 30, and a slide rail is provided inside the rotating arm 31. That is, the ejection cylinder drives the guide portion 30 to move vertically, and the ejection cylinder slides in the rotating arm 31 so that the guide portion 30 can move vertically and rotate around the yarn package, and drive it to be transported to the knotting assembly 4.
[0047] Furthermore, the automatic knotting machine also includes a yarn pressing mechanism 5 and a yarn dropping slide 6. The yarn dropping slide 6 is arranged opposite to the yarn feeding slide 21, and the transverse movement mechanism 22 is arranged between the yarn dropping slide 6 and the yarn feeding slide 21. The yarn pressing mechanism 5 is close to the rotary component 3 and is arranged vertically along the yarn dropping slide 6. After the knotting is completed, the yarn package is moved to the working position corresponding to the yarn pressing mechanism 5 by the transverse movement mechanism 22. After the yarn package is pressed by the yarn pressing mechanism 5, the flipping bowl 220 is turned to the yarn dropping slide 6.
[0048] To explain, the moving mechanism 22 is driven by a push cylinder. In this embodiment, the push cylinder is close to the moving mechanism 22 and is located between the moving mechanism 22 and the recovery device 20. That is, when the yarn needs to be knotted, the push cylinder is stationary. After the yarn is knotted, the push cylinder is activated, which drives the moving mechanism 22 to move from the working position corresponding to the rotary component 3 to the working position corresponding to the yarn pressing mechanism 5 to perform the corner pressing work on the yarn.
[0049] It can be explained that the yarn pressing mechanism 5 includes a yarn pressing cylinder and a yarn pressing bowl connected to the yarn pressing cylinder. The yarn pressing bowl is set to correspond to the flipping bowl 220 to ensure that when the yarn pressing mechanism 5 presses the yarn cone, the two bowls form an opposing state, which can effectively and accurately press the yarn cone and ensure the smoothness of the entire production process.
[0050] Furthermore, a regulating valve 8 is provided on the frame 1; preferably, in this embodiment, the regulating valve 8 is a pneumatic pressure regulating valve to control the air pressure of all cylinders in the automatic knotting machine, so as to accurately regulate the working pressure of the cylinders and ensure that the components in the entire equipment can operate stably and smoothly, with greater flexibility.
[0051] Furthermore, a warning device 7 is provided at one end of the frame 1 near the rotating assembly 3. When the automatic knotting machine malfunctions, the warning device 7 will provide a light warning. Optionally, the warning device 7 is a three-color warning light, typically including red, yellow, and green lights. The red light indicates an emergency or serious malfunction, requiring immediate machine stoppage and inspection. The yellow light indicates a need for attention or potential malfunction risk, requiring operators to remain vigilant and conduct necessary checks. The green light indicates that the automatic knotting machine is operating normally and requires no special attention. In other words, through the setting of the warning device 7, operators can more intuitively understand the operating status of the automatic knotting machine, facilitating timely implementation of corresponding measures to ensure the normal operation of the equipment and the safety of production.
[0052] Understandably, by cooperating with each component, the smooth transfer of yarn bobbins and automatic knotting operations are achieved, avoiding yarn scattering and tangling problems that occur during transportation and dyeing, reducing reliance on manual labor, and improving production efficiency. Specifically, a sensing unit detects the yarn bobbins, and after confirmation, the yarn bobbins are transported to the rotating component 3. The guide part 30 ensures smooth transfer and positioning of the yarn bobbins, guiding them into the knotter 41 to complete the knotting operation. After knotting, excess yarn tails are collected by the recycling device 20 to prevent scattering and accumulation of yarn tails, thus maintaining the cleanliness of the work area. The cooperation between the knotter 41 and the shearing part 42 ensures the accuracy of the knotting operation and the timely handling of yarn tails, improving the smoothness of the entire automatic knotting machine operation, thereby increasing production efficiency.
[0053] The second embodiment of this application provides a winding machine for conveying yarn packages. The winding machine is used to convey the yarn packages to the conveying assembly of an automatic knotting machine provided in the first embodiment, and to knot the yarn packages in conjunction with the knotting assembly.
[0054] Furthermore, the winding machine includes a sensing device and a tube changing device. When the sensing device determines that the yarn package has reached the preset length, the tube changing device is activated to transfer the yarn package to the yarn feeding chute of the automatic knotting machine, and a new empty tube is installed for yarn winding.
[0055] Specifically, the winding machine and the automatic knotting machine work closely together to complete the knotting of the yarn package. The length of the yarn package is monitored in real time by a sensing device. When the yarn package reaches the preset length, the sensing device sends a signal to the tube-changing device, which transports the yarn package to the yarn feeding chute and replaces the empty tube in the winding machine to continue winding the yarn. This achieves automated operation, reduces manual intervention, improves production efficiency, and ensures the continuity of the yarn package during the knotting process. Preferably, the sensing device includes, but is not limited to, photoelectric sensors, mechanical sensors, or ultrasonic sensors. In practical applications, the appropriate sensor is selected and optimized based on actual production needs and environmental conditions to ensure the high efficiency and stability of the entire knotting process.
[0056] Please refer to point 1. Figure 3 and Figures 6-9 Operating principle:
[0057] Specifically, in practical applications, a full bobbin of yarn is conveyed to an automatic knotting machine via a conveyor belt from a matching automatic bobbin changing and winding machine. It is then conveyed from the yarn inlet chute 21 into a rotating bowl 220. The entry of the bobbin is detected by a sensing unit, activating the first support part 221 and the second support part 222 to form a fixing column 224, securing the bobbin within the rotating bowl 220. The first drive motor 223 rotates the rotating bowl 220, causing the bobbin to rotate. A lifting cylinder 231 pushes out the suction nozzle 230, while a suction fan 232 starts working, drawing the tail yarn into the suction nozzle 230 for fixation. The rotating bowl 220 rotates to the working position corresponding to the rotating assembly 3, with the guide part 30 against the outer surface of the bobbin. After rotating one and a half turns, the tail yarn and one loop of yarn are guided to the knotter 41. Simultaneously, the drive mechanism 40 of the knotting assembly 4 operates, and the knotter 41 adheres to the guide part 30 to complete the knotting. The cutting part... 42 are in place simultaneously. After knotting, the shearing part 42 cuts off the excess tail yarn. The remaining tail yarn is then sucked into the recycling device 20 through the yarn suction nozzle 230, thus completing the knotting process. Afterward, the knotter 41 and the shearing part 42 are retracted, the suction fan 232 stops working, the yarn suction nozzle 230 is retracted, and the guide part 30 is also moved to the outside of the frame 1. At the same time, the rotating arm 31 returns to its original position, and the transverse mechanism 22 drives the flip bowl 220 to move to the working position corresponding to the yarn pressing mechanism 5. The yarn pressing mechanism 5 pushes out the yarn pressing bowl to perform the corner pressing process on the yarn package. After this process is completed, the push-out cylinder is retracted, the first drive motor 223 is run, and the flip bowl 220 is turned to the yarn doffing slide 6. The yarn package push-out cylinder set opposite to the flip bowl 220 pushes the yarn package out of the flip bowl 220, so that the yarn package falls into the yarn transport trolley through the yarn doffing slide 6. Finally, the entire process ends, and all parts return to their original positions.
[0058] It should be noted that the order of the embodiments described above is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. The processes depicted in the accompanying drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
