DETAILED DESCRIPTION

[0017] The utility model provides a color selection feed structure, in order to make the purpose, technical scheme and effect of the utility model more clear, explicit, the following refers to the figure and raises example to the utility model further detailed explanation. It should be understood that the specific embodiment described here is only used to explain the utility model, and is not used to limit the protection scope of the utility model.

[0018] In this paper, "after" is the direction of the feed rod from the waiting position to the feed position, and the direction of "after" is opposite to "before".

[0019] Please refer to Figures 1 to 3 The utility model provides a color selection feed structure, including color selection seat 1, the shell 2 of setting below color selection seat 1, the hook plate 3 of setting in shell 2 can swing, the feed rod 4 of setting on hook plate 3, the vertical movement of feed plate 5 in shell 2 can, and the color selection pin 6 for driving feed plate 5 to move down is set in color selection seat 1, the driver 7 of driving color selection pin 6 to move down is equipped on color selection seat 1, color selection pin 6 drives feed plate 5 to move down;The hook plate 3 is located in the rear side of feed plate 5, and one end of hook plate 3 forms pull head 31, and the other end forms hook head 32, the pull head 31 is hauled by traction structure, makes hook head 32 form the movement tendency of driving feed plate 5 to move up.

[0020] Actually, hook plate 3 plays the role of lever, in non-working state, since the pull head 31 of hook plate 3 is hauled down by traction structure, then the hook head 32 of hook plate 3 will form reverse force, forms the force of driving feed plate 5 to move up, so that feed plate 5 and feed rod 4 are in waiting position. When the driver 7 starts to drive color selection pin 6 in color selection seat 1 to move down, color selection pin 6 overcomes the traction force of traction structure, drives feed plate 5 to move down, feed plate 5 drives hook plate 3 to swing in the process of moving down, and then makes feed rod 4 swing to feed position. Through the control of driver 7 to color selection pin 6 and the mutual cooperation between hook plate 3 and feed plate 5, realize the switching of feed rod 4 between waiting position and feed position, to complete the color selection feed work.

[0021] Compared with the structure that the swing plate is located below the yarn feeding plate 5 and adopts a hinged mode in the prior art, the overall height is effectively reduced. This makes the installation of the structure in the knitting machine more convenient, can better adapt to the limited space inside the knitting machine, reduces the occupation of the space, and improves the utilization rate of the internal space of the knitting machine. Because the overall height is reduced and the occupied space is reduced, the color selection yarn feeding structure can adapt to more types of knitting machines. Under the current trend of integration and diversification of knitting equipment, its wide adaptability makes it applicable to different types of knitting equipment, greatly expands the application range, meets the requirements of the industry for equipment versatility, helps to promote the wide application of the color selection yarn feeding technology in the knitting industry, and promotes the upgrading and development of the knitting equipment.

[0022] Specifically, referring to Figure 4 The shell 2 is provided with at least two guide pins 92 matched with the waist-shaped hole 511, and the hook head 32 is pressed against the bottom surface of the horizontal plate body 52. The waist-shaped hole 511 is arranged on the vertical plate body 51 of the yarn feeding plate 5 and is matched with the at least two guide pins 92 in the shell 2. When the yarn feeding plate 5 moves up and down, the guide pins 92 slide accurately in the waist-shaped hole 511, which not only effectively limits the moving direction of the yarn feeding plate 5, but also absorbs part of the impact force generated by movement. This makes the yarn feeding plate 5 always run stably during the entire color selection yarn feeding process, greatly reducing the possibility of shaking and deviation. The yarn feeding rod 4 is installed on the yarn feeding plate 5, and the stable movement of the yarn feeding plate 5 directly ensures the stability of the yarn feeding action of the yarn feeding rod 4, thereby improving the stability and accuracy of yarn conveying, and providing a solid guarantee for producing high-quality knitted products.

[0023] The special design of the hook head 32 on the hook plate 3 ensures that the horizontal plate body 52 does not interfere with the movement of the main body of the hook plate 3, and can always stably press against the bottom surface of the horizontal plate body 52. This direct pressing connection forms an efficient force transmission path. When the hook plate 3 swings, the force can be quickly and stably transmitted to the yarn feeding plate 5 to drive it to move upward. When the color selection pin 6 drives the yarn feeding plate 5 to move downward, the close contact between the bottom surface of the horizontal plate body 52 and the hook head 32 can maintain the stability of the structure and prevent unnecessary displacement or looseness of the yarn feeding plate 5 during movement. This stable structure connection not only reduces the wear and failure risk between components due to improper cooperation, but also prolongs the service life of the entire color selection yarn feeding structure, reduces the maintenance frequency and cost of the equipment.

[0024] The lower pressing body 53 is in transmission cooperation with the color selecting pin 6, so that vertical movement of the color selecting pin 6 can be accurately converted into vertical movement of the yarn feeding plate 5. When the color selecting pin 6 moves downward, the distance and speed of the yarn feeding plate 5 can be accurately controlled through cooperation with the lower pressing body 53, thereby accurately driving the yarn feeding rod 4 to swing from the waiting position to the yarn feeding position, effectively improving the precision and accuracy of yarn feeding, ensuring the stability and consistency of yarn conveying, and being beneficial to produce high-quality knitted products.

[0025] Preferably, the waist-shaped hole 511 is provided with two, and the guide pin 92 is provided with two and cooperates with the corresponding waist-shaped hole 511 respectively. The two waist-shaped holes 511 and the two guide pins 92 are provided and cooperate one by one, which can provide more balanced and stable support and guidance for the yarn feeding plate 5 during its upward and downward movement. When the yarn feeding plate 5 moves under the action of the color selecting pin 6 or the hook plate 3, the two guide pins 92 slide in the corresponding waist-shaped holes 511 respectively, effectively preventing the yarn feeding plate 5 from tilting, shaking and other unstable conditions. This stable movement mode is crucial for the yarn feeding rod 4 to accurately complete the yarn feeding action, which can ensure the stability of the yarn during conveying, avoid uneven yarn tension and winding caused by unstable movement of the yarn feeding plate 5, and thus improve the quality of knitted products.

[0026] Preferably, the traction structure is a tension spring 8, one end of which is fixed in the shell 2, and the other end is connected with the pull head 31 of the hook plate 3. One end of the tension spring 8 is fixed in the shell 2, and the other end is connected with the pull head 31 of the hook plate 3, which can provide stable and continuous traction force for the hook plate 3. In the non-working state, the elastic potential energy of the tension spring 8 makes the hook head 32 of the hook plate 3 always maintain the tendency to press against the bottom surface of the horizontal plate body 52 of the yarn feeding plate 5, ensuring that the yarn feeding plate 5 and the yarn feeding rod 4 are stably in the waiting position. When the color selecting pin 6 drives the yarn feeding plate 5 to move downward to overcome the tension of the tension spring 8, as soon as the force of the color selecting pin 6 disappears, the tension spring 8 can quickly pull the hook plate 3 back to the original position, driving the yarn feeding plate 5 and the yarn feeding rod 4 to reset, ensuring the continuity and stability of the color selecting and yarn feeding action.

[0027] Specifically, the driver 7 includes a control valve 71 arranged on the color selection seat 1 and a pressure supply channel 72 arranged in the color selection seat 1, the color selection seat 1 is provided with a yarn selection guide hole 11 in sliding connection with the color selection pin 6, the pressure supply channel 72 is in communication with the yarn selection guide hole 11, and the valve core of the control valve 71 is used to control the conduction or disconnection of the pressure supply channel 72 and the yarn selection guide hole 11. When it is necessary to perform the color selection yarn feeding operation, the control valve 71 is opened, the pressure supply channel 72 delivers air pressure to the yarn selection guide hole 11, pushes the color selection pin 6 to move downward, and then drives the yarn feeding plate 5 and the yarn feeding rod 4 to perform the yarn feeding action; when the yarn feeding action is completed, the control valve 71 is closed, the air pressure disappears, and the color selection pin 6 is reset under the action of other structures (such as the tension spring 8). This precise control method can ensure the accuracy and timeliness of the color selection yarn feeding action, meet the strict requirements of different knitting processes on the yarn feeding rhythm and sequence, and effectively improve the quality and production efficiency of knitted products.

[0028] In fact, the color selection mechanism can include multiple groups of color selection yarn feeding structures, and has the ability to simultaneously control the actions of multiple groups of color selection yarn feeding structures to realize the selection of multiple yarns. The number of the driver 7, the color selection pin 6, the yarn feeding plate 5, the yarn feeding rod 4 and the hook plate 3 is multiple and one-to-one correspondence. Multiple groups of color selection yarn feeding structures are arranged side by side. In order to clearly show the structure, only one yarn feeding plate 5 and one yarn feeding rod 4 are drawn. Figure 1 And Figure 2 Only one yarn feeding plate 5 and one yarn feeding rod 4 are drawn.

[0029] Specifically, the shell 2 includes two parallel arranged metal plates, the two metal plates are connected by a plurality of shaft pins and form a hollow mounting cavity, the bottom of the color selection seat 1 is in a front low and rear high structure, the color selection pin 6 is located on the front end of the color selection seat 1, correspondingly, the top of the metal plate is in a front low and rear high structure, the yarn feeding plate 5 is located on the front end of the shell 2, and the hook plate 3 is located on the rear end of the shell 2. This design not only ensures the strength and stability of the shell 2, but also effectively utilizes the space, so that the installation of the internal components is more regular. At the same time, the bottom of the color selection seat 1 and the top of the metal plate are in a front low and rear high structure, the yarn feeding plate 5 is located on the front end of the shell 2, and the hook plate 3 is located on the rear end. This reasonable layout of the positions of the components makes the entire color selection yarn feeding structure more compact. The compact structure not only reduces the space occupied by the equipment, but also facilitates the installation and integration in the knitting machine and other equipment, and improves the space utilization of the equipment.

[0030] One of the shaft pins serves as a pivot 91 for rotating with the hook plate 3, providing stable support and rotating basis for the swing of the hook plate 3. The precise fit of the shaft pin can reduce the frictional resistance when the hook plate 3 swings, so that the hook plate 3 can move more smoothly. The color selection pin 6 is located at the front end of the color selection seat 1, and the yarn feeding plate 5 is located at the front end of the shell 2, so that the corresponding position relationship makes the movement path of the color selection pin 6 driving the yarn feeding plate 5 more direct and smooth, avoiding the movement interference or jamming phenomenon caused by unreasonable component position, and helping to improve the efficiency and accuracy of the color selection and yarn feeding action.
