[0001] The utility model relates to the field of knitting technology, especially to a yarn releasing and cutting structure of a color selection thread selector. BACKGROUND
[0002] With the continuous development of the textile industry, the demand for the refinement and diversification of yarn processing of the color selection thread selector is increasing, but the existing color selection thread selector is difficult to meet the requirements. For example, the existing patent CN 216074229 provides a color selection mechanism, in which the yarn releasing rod and the yarn cutting rod are hinged on the same lever plate, and the lever plate is driven to swing by the driver, thereby driving the yarn releasing rod and the yarn cutting rod to work synchronously. This structure realizes the functions of yarn releasing and cutting to some extent, but also has obvious limitations. Since the yarn releasing rod and the yarn cutting rod work synchronously, the time interval of yarn releasing and yarn cutting is fixed, and it is difficult to make different action times for different varieties of yarn. Different varieties of yarn have different characteristics such as thickness, material, and tensile properties, and the required yarn releasing and cutting time is also different in the textile process. The fixed time interval of yarn releasing and cutting cannot meet these diversified needs, which may cause problems such as uneven tension, broken ends, and waste of yarn in the textile process, thereby affecting the quality and production efficiency of textiles.
[0003] Therefore, it is urgent to develop a yarn releasing and cutting structure of a color selection thread selector that can flexibly adjust the time interval of yarn releasing and cutting and adapt to the needs of different varieties of yarn. SUMMARY
[0004] In view of the above shortcomings of the prior art, the purpose of the utility model is to provide a yarn releasing and cutting structure of a color selection thread selector, which can flexibly adjust the time interval of yarn releasing and cutting and adapt to the needs of different varieties of yarn.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Detailed Implementation
[0022] This utility model provides a yarn feeding and cutting structure for a yarn selector. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.
[0023] To better demonstrate the yarn feeding and cutting structures, Figure 1 and Figure 2 The yarn feeding structure and the yarn cutting structure are shown separately. In fact, the yarn feeding structure and the yarn cutting structure are set up side by side. Under the main view projection, the yarn feeding structure and the yarn cutting structure will overlap.
[0024] Please see Figures 1 to 3The utility model provides a kind of yarn releasing and cutting structure of color selection tuning wire, including color selection seat 1, the shell 2 being arranged below color selection seat 1, the yarn releasing member 3 and the yarn cutting member 4 being swingably arranged in shell 2, and the yarn releasing pushpin 51 and the yarn cutting pushpin 52 vertically slidingly arranged in color selection seat 1, the yarn releasing drive 6 and the yarn cutting drive 7 are equipped on color selection seat 1, the yarn releasing drive 6 is used to drive the yarn releasing pushpin 51 to move down, and the yarn releasing pushpin 51 drives the yarn releasing member 3 to swing to yarn releasing position, the yarn cutting drive 7 is used to drive the yarn cutting pushpin 52 to move down, and the yarn cutting pushpin 52 drives the yarn cutting member 4 to swing to yarn cutting position, the yarn releasing member 3 is kept in standby position by first traction mechanism, and the yarn cutting member 4 is kept in standby position by second traction mechanism.
[0025] When the new yarn needs to be introduced in the textile process, the control system issues a command to drive the yarn feeding rod 9 to swing from the standby position to the yarn feeding position. During this process, the movement trajectory and position of the yarn feeding rod 9 are precisely designed and controlled to ensure that it can accurately reach the required position for yarn feeding, preparing for the subsequent yarn releasing operation. After the yarn feeding rod 9 reaches the yarn feeding position, the yarn releasing drive 6 is activated to drive the yarn releasing pushpin 51 to move down. The yarn releasing pushpin 51 drives the yarn releasing member 3 connected to it to swing, and the yarn releasing member 3 overcomes the traction force of the first traction mechanism to swing from the standby position to the yarn releasing position. At this time, the yarn is released by the yarn releasing member 3 and begins to be transported along a specific path into the yarn feeding area determined by the yarn feeding rod 9, providing the required yarn for textile. After the yarn releasing is completed, the yarn feeding rod 9 returns to the standby position under the action of the corresponding driving device. The resetting action of the yarn feeding rod 9 needs to be coordinated with the yarn releasing and cutting actions to ensure that the yarn is not disturbed or has abnormal tension during transportation. After the yarn feeding rod 9 is reset, the yarn cutting drive 7 is activated to drive the yarn cutting pushpin 52 to move down. The yarn cutting pushpin 52 drives the yarn cutting member 4 to swing, and the yarn cutting member 4 overcomes the traction force of the second traction mechanism to swing from the standby position to the yarn cutting position. In the yarn cutting position, the yarn cutting member 4 cuts the yarn that has completed the yarn feeding task, making the length of the yarn meet the requirements of the textile process, and preparing for the next yarn feeding and releasing operation.
[0026] Since the yarn releasing and cutting are controlled by independent drives (yarn releasing drive 6 and yarn cutting drive 7), pushpins (yarn releasing pushpin 51 and yarn cutting pushpin 52), and traction mechanisms (first traction mechanism and second traction mechanism), the yarn releasing and cutting actions can be independently performed according to actual needs without interference.
[0027] Compared with the yarn releasing rod 32 and the yarn cutting rod 42 in the prior art, the yarn releasing time interval and the yarn cutting time interval are fixed. However, the yarn releasing action and the yarn cutting action are controlled by the independent yarn releasing driver 6 and the yarn cutting driver 7 respectively, so that the yarn releasing time interval and the yarn cutting time interval can be flexibly adjusted according to the thickness, material and tensile properties of different types of yarns. In this way, the diversified yarn processing requirements can be met, and problems such as uneven tension, broken ends and waste of yarns in the weaving process caused by improper time interval can be avoided.
[0028] Specifically, referring to Figure 4 The yarn releasing member 3 includes a first lever plate 31 and a yarn releasing rod 32 hinged to the rear end of the first lever plate 31. The front end 311 of the first lever plate 31 is in transmission with the yarn releasing push pin 51. This structure can make the driving force of the yarn releasing push pin 51 be transmitted to the yarn releasing member 3 more effectively. The yarn releasing rod 32 is hinged to the rear end of the first lever plate 31, so that the yarn releasing rod 32 can swing around the hinge point. This hinged structure gives the yarn releasing rod 32 greater freedom of movement, so that it can adjust the angle and position of the yarn releasing according to different weaving requirements. At the same time, through the transmission of the first lever plate 31, the yarn releasing push pin 51 can more flexibly control the swing amplitude and speed of the yarn releasing rod 32, so as to realize the accurate adjustment of the yarn releasing amount and the yarn releasing speed.
[0029] Further, the first traction mechanism includes a first tension spring 81, one end of which is fixed on the shell 2, and the other end is connected with the rear end 312 of the first lever plate 31. The first tension spring 81 has elastic potential energy. After the yarn releasing member 3 completes the yarn releasing action, the yarn releasing driver 6 stops driving, and the yarn releasing push pin 51 no longer exerts force on the first lever plate 31. At this time, the elastic potential energy stored in the first tension spring 81 is released, pulling the rear end of the first lever plate 31, so that the first lever plate 31 and the yarn releasing rod 32 hinged thereto are quickly reset to the waiting position. This automatic reset function ensures that the yarn releasing member 3 can be ready for the next yarn releasing operation in time, improving the continuity and efficiency of the weaving work.
[0030] Specifically, referring to Figure 5The yarn cutting member 4 includes a second lever plate 41 and a yarn cutting lever 42 hinged at the front end of the second lever plate 41. The front end 411 of the second lever plate 41 is in transmission with the yarn cutting push pin 52. This direct transmission mode can ensure that the power of the yarn cutting driver 7 is accurately and efficiently transmitted to the yarn cutting member 4. When the yarn cutting push pin 52 moves downward under the drive of the yarn cutting driver 7, it can quickly swing the second lever plate 41, and in turn make the yarn cutting lever 42 hinged at the front end thereof quickly reach the yarn cutting position and complete the yarn cutting action. Compared with indirect or complex transmission structure, energy loss and action delay are reduced, the accuracy and efficiency of yarn cutting are improved, the yarn is accurately cut at the right time, and the quality and production efficiency of the textile are improved.
[0031] Further, the second traction mechanism includes a second tension spring 82, one end of which is fixed on the shell 2, and the other end is connected with the rear end 412 of the second lever plate 41. After the yarn cutting push pin 52 drives the second lever plate 41 to swing and complete the yarn cutting action, the second tension spring 82 can quickly pull the second lever plate 41 and the yarn cutting lever 42 back to the waiting position by its elastic force. This makes the yarn cutting member 4 accurately reset after each yarn cutting action, ensuring the consistency and reliability of the yarn cutting action. In the continuous textile production process, stable resetting of the yarn cutting member 4 helps to maintain stable operation of the entire textile system, reduces abnormal yarn cutting problems caused by position deviation of the yarn cutting member 4, and improves the quality and production efficiency of the textile.
[0032] Specifically, the yarn releasing driver 6 includes a first control valve 61 arranged on the color selection seat 1 and a first pressure supply channel 62 arranged in the color selection seat 1. The color selection seat 1 is provided with a first guide hole 63 in sliding connection with the yarn releasing push pin 51. The first pressure supply channel 62 is in communication with the first guide hole 63. The spool of the first control valve 61 is used to control the conduction or disconnection of the first pressure supply channel 62 and the first guide hole 63, so as to realize accurate control of the yarn releasing push pin 51. This driving mode based on the control valve and the pressure supply channel has relatively fast response speed. In the textile production process, different colors or varieties of yarn need to be quickly switched. The first control valve 61 can quickly control the on-off of the pressure, so that the yarn releasing push pin 51 responds in time and drives the yarn releasing member 3 to quickly complete the yarn releasing action.
[0033] Further, the yarn cutting driver 7 comprises a second control valve 71 arranged on the color selection seat 1 and a second pressure supply channel 72 arranged in the color selection seat 1, the color selection seat 1 is provided with a second guide hole 73 in sliding connection with the yarn cutting push rod 52, the second pressure supply channel 72 is in communication with the second guide hole 73, the spool of the second control valve 71 is used to control the conduction or disconnection of the second pressure supply channel 72 and the second guide hole 73, so as to accurately control the yarn cutting push rod 52. Based on the yarn cutting driving mode of the control valve and the pressure supply channel, the response speed is very fast. In textile production, the yarn cutting operation needs to be closely matched with other processes, and the second control valve 71 can quickly realize the on-off of the pressure, so that the yarn cutting push rod 52 responds quickly, and the yarn cutting member 4 completes the yarn cutting action in time.
[0034] Preferably, the first control valve 61 and the second control valve 71 are arranged side by side, and the first guide hole 63 and the second guide hole 73 are arranged side by side. This layout makes full use of the space of the color selection seat 1, making the internal structure of the color selection and tone selector more regular and compact. Compared with a scattered or irregular layout, it can effectively reduce the space occupation, facilitate installation and arrangement in a limited textile equipment space, and also facilitate the stability and compactness of the overall structure.
[0035] In the embodiment, the shell 2 comprises two parallel metal plates connected by a plurality of shaft pins and constitutes a hollow mounting cavity, one of the shaft pins serving as a pivot 11, and the yarn feeding member 3 and the yarn cutting member 4 both swing around the pivot 11. Using the same pivot 11 as the swing center of the yarn feeding member 3 and the yarn cutting member 4 simplifies the overall structural design. Compared with arranging independent swing support structures for the yarn feeding and cutting members 4, the number of parts and the assembly complexity are reduced. Not only the machining cost and assembly difficulty in the manufacturing process are reduced, but also the reliability of the product is improved. The pivot 11 as a fixed rotation center provides an accurate positioning reference for the yarn feeding and cutting actions, so that the yarn feeding rod 32 and the yarn cutting rod 42 are not easy to deviate or shake during swinging. This is crucial for the color selection and tone selector which needs to accurately control the timing and position of yarn feeding and cutting, effectively reducing the problems of inaccurate yarn feeding amount and cutting position deviation caused by unstable swinging, greatly improving the working accuracy of the color selection and tone selector, and further improving the quality of textiles.
