[0021] The present invention provides a needle sealing method, device, equipment and storage medium for a knitting machine. The present invention obtains fabric structure data according to the regular characteristics of the fabric, and the fabric structure data reflects the way the knitting machine weaves the fabric. Then, a needle sealing data table is generated according to the knitting machine needle data inherent in the knitting machine, so as to obtain a needle sealing data table with invalid needle data. The jacquard pattern data is expanded according to actual needs, so that the jacquard pattern data is expanded to form expanded pattern data that meets the fabric weaving size, and a needle sealing signal is inserted into the expanded pattern data according to the needle sealing data table or a needle sealing signal is output to the knitting machine, so that the knitting machine can seal the needles according to the invalid needle data in the needle sealing data table when performing jacquard according to the expanded pattern data, even if some needles do not participate in the weaving process, so that various knitting machines can meet the weaving requirements of special fabrics, and there is no need to disassemble and assemble the needle structure of the knitting machine, making the entire weaving process more convenient.

[0022] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" or "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of the knitting machine needle sealing method in the embodiment of the present invention comprises:

[0024] 101. Acquire fabric structure data and knitting machine needle data, and establish a needle blocking data table according to the fabric structure data and the knitting machine needle data; the needle blocking data table includes invalid needle data whose actions are prohibited;

[0025] In this embodiment, fabric structure data is obtained according to the regular characteristics of the fabric, and the fabric structure data reflects the way the knitting machine weaves the fabric. For example, a special fabric requires one cycle of three needles during weaving, and the third needle does not participate in the weaving. Then, a needle blocking data table is generated according to the knitting machine needle data inherent in the knitting machine, so as to obtain a needle blocking data table with invalid needle data. Even a knitting machine with a full needle arrangement can meet the weaving requirements of special fabrics.

[0026] It should be noted that the knitting machine needle data is the inherent parameters of the corresponding knitting machine, which mainly includes the number of knitting needles of the knitting machine, the number of output channels and the direction of the knitting needle movement (ie, upward or downward needle output).

[0027] 102. Obtain jacquard pattern data;

[0028] In this embodiment, the jacquard pattern data is an initial weaving pattern, and corresponding jacquard pattern data needs to be acquired according to weaving requirements to provide a weaving basis for subsequent fabrics.

[0029] 103. Perform expansion processing on the jacquard pattern data according to the needle sealing data table to obtain expanded pattern data;

[0030] 104. Outputting knitting needle motion data according to the unfolding pattern data and the needle sealing data table;

[0031] In this embodiment, since the size of the fabric does not correspond to the size of the jacquard pattern data, the jacquard pattern data needs to be expanded and processed. The jacquard pattern data is expanded according to actual needs to form expanded pattern data that meets the fabric weaving size, and a needle closing signal is inserted into the expanded pattern data according to the needle closing data table or a needle closing signal is output to the knitting machine, so that the knitting machine can close the needles according to the invalid needle data in the needle closing data table when performing jacquard according to the expanded pattern data. Even if some needles do not participate in the weaving process, various knitting machines can meet the weaving requirements of special fabrics without disassembling the needle structure of the knitting machine, making the entire weaving process more convenient.

[0032] In the present invention, fabric structure data is obtained according to the regular characteristics of the fabric, and the fabric structure data reflects the way the knitting machine weaves the fabric. Then, a needle blocking data table is generated according to the knitting machine needle data inherent in the knitting machine, so as to obtain a needle blocking data table with invalid needle data. The jacquard pattern data is expanded according to actual needs, so that the jacquard pattern data is expanded to form expanded pattern data that meets the fabric weaving size, and a needle blocking signal is inserted into the expanded pattern data according to the needle blocking data table or a needle blocking signal is output to the knitting machine, so that the knitting machine can block the needles according to the invalid needle data in the needle blocking data table when performing jacquard according to the expanded pattern data. Even if some needles do not participate in the weaving process, various knitting machines can meet the weaving requirements of special fabrics without disassembling the needle structure of the knitting machine, making the entire weaving process more convenient.

[0033] See also Figure 2 The second embodiment of the needle sealing method of a knitting machine in the embodiment of the present invention comprises:

[0034] 201. Acquire knitting machine equipment information, and extract knitting needle data according to the knitting machine equipment information;

[0035] 202. Perform numbering processing on the knitting needle data, number each knitting needle, and generate knitting needle number data;

[0036] In this embodiment, the knitting machine equipment information is acquired in advance, and the corresponding knitting needle data is extracted therefrom, and each knitting needle in the knitting needle data is numbered, and a marking certificate is provided for the knitting needle through the numbering.

[0037] 203. Acquire fabric structure data according to the distribution of the fabric structure;

[0038] In this embodiment, various fabrics are basically composed of geometric arrangements through regular organizational structures, so the corresponding rules for weaving the fabric can be obtained by acquiring the fabric structure data, such as 4 stitches as a cycle, in which the second and third stitches are not involved in the weaving, etc.

[0039] It should be noted that the fabric structure data can be pre-stored in a memory and can be quickly retrieved according to the properties of the fabric when needed.

[0040] 204. Performing comparison processing on the knitting needle number data according to the fabric structure data, and generating a needle sealing data table;

[0041] In this embodiment, a needle sealing data table having numbered needles is correspondingly generated according to the fabric structure data and the needle numbering data, and invalid needle data can be easily identified by numbering.

[0042] 205. Obtain the total number of knitting needles and the total number of output paths according to the knitting needle data;

[0043] 206. Graphically process the jacquard pattern data according to the total number of knitting needles and the total number of output paths, and expand the jacquard pattern data into pre-expanded pattern data;

[0044] In this embodiment, the jacquard pattern data is expanded according to the total number of needles and the total number of output routes of the knitting machine, so that the jacquard pattern data is expanded to form expanded pattern data that meets the fabric weaving size; for ease of understanding, the following example is used for explanation: the jacquard pattern data is set to a pattern with an aspect ratio of 4*5, the total number of needles of the knitting machine is 100 needles, and the total number of output routes of the knitting machine is 60 routes, so the expanded pattern data after expansion is a pattern of 100*60.

[0045] 207. Insert the sealing needle action data into the pre-expanded pattern data according to the sealing needle data table to obtain the expanded pattern data;

[0046] 208. Obtain the invalid knitting needle number in the sealed needle data table and the knitting needle number of the expanded pattern data;

[0047] In this embodiment,

[0048] 209. Compare the invalid knitting needle number with the knitting needle number of the expanded pattern data;

[0049] 210. If the invalid knitting needle number is consistent with the knitting needle number of the expanded pattern data, insert a needle-sealing signal into the knitting needle number corresponding to the expanded pattern data;

[0050] 211. If the invalid knitting needle number is inconsistent with the knitting needle number of the expanded pattern data, insert an action signal into the knitting needle number corresponding to the expanded pattern data;

[0051] In this embodiment, invalid knitting needle data in the needle blocking data table is extracted, wherein the invalid knitting needle data carries a number, and then the numbers are compared one by one with the knitting needle numbers corresponding to each needle action of the expanded pattern data. If there is consistency, a needle blocking signal is inserted into the needle position corresponding to the expanded pattern data, so that no knitting action is generated during output. The needle blocking signal may be a level signal that is different from the knitting machine action signal. For example, the knitting machine controls the knitting needle action through 0 and 1 signals, and here a 3 signal is assigned to the knitting needle, so that no action will occur even if the knitting needle receives a 0 or 1 signal, thereby achieving a needle blocking effect. Otherwise, the action signal is inserted normally. When the knitting machine receives the expanded pattern data, the knitting needle is controlled to perform knitting according to the needle blocking signal and the action signal attached to the expanded pattern data. By inserting the needle blocking signal and the action signal into the expanded pattern data in advance, the knitting machine can automatically perform the corresponding knitting action after receiving the expanded pattern data.

[0052] See also Figure 3 The third embodiment of the needle sealing method of a knitting machine in the embodiment of the present invention comprises:

[0053] 301. Obtain the number of invalid knitting needles according to the invalid knitting needle data in the needle sealing data table;

[0054] 302. Obtain the total number of knitting needles and the total number of output paths according to the knitting needle data;

[0055] 303. Obtain the effective number of knitting needles according to the total number of knitting needles and the number of invalid knitting needles;

[0056] 304. Graphically process the jacquard pattern data according to the effective number of knitting needles and the total number of output paths, and expand the jacquard pattern data into expanded pattern data;

[0057] In this embodiment, the jacquard pattern data is expanded in advance according to the number of effective knitting needles, that is, the expanded pattern data is expanded only according to the number of operating knitting needles, which greatly reduces the calculation efficiency of the early stage of expanding the pattern data and reduces the influence of the inactive knitting needles on the expansion of the pattern data.

[0058] For ease of understanding, the following example is used to illustrate: the jacquard pattern data is set to a pattern with an aspect ratio of 4*5, the total number of needles of the knitting machine is 100 needles, the total number of output channels of the knitting machine is 60 channels, and the number of invalid needles is 50 needles, so the expanded pattern data after expansion is a 50*60 pattern.

[0059] 305. Verify the needle sealing data table and the knitting machine needle data;

[0060] 306. If the knitting needle number of the knitting machine is consistent with the invalid knitting needle number, a needle sealing signal is output;

[0061] 307. If the knitting needle number of the knitting machine is inconsistent with the invalid knitting needle number, an action signal is outputted corresponding to the unfolded pattern data;

[0062] In this embodiment, the expanded pattern data only includes the pattern data of the action needles, so when the expanded pattern data is input into the knitting machine, the knitting needles of the knitting machine need to be controlled to move according to the needle blocking data table. When it is detected that the knitting needles on the knitting machine exist in the needle blocking data table, a needle blocking signal is sent to the knitting needle so that the knitting needle does not perform the knitting action. If the knitting needles do not exist in the needle blocking data table, the knitting action is performed normally according to the expanded pattern data.

[0063] See also Figure 4 The third embodiment of the needle sealing method of a knitting machine in the embodiment of the present invention comprises:

[0064] 401. Subtract the total number of knitting needles from the number of invalid knitting needles to obtain a difference result; the difference result is the number of valid knitting needles;

[0065] In this embodiment, the effective knitting needle number can be quickly obtained by subtracting the invalid knitting needle number from the total knitting needle number, and the unfolded pattern data can be quickly obtained according to the effective knitting needle number.

The following is a description of the knitting machine needle sealing device in the embodiment of the present invention.

[0067] The needle sealing module 501 is used to obtain fabric structure data and knitting machine needle data, and to establish a needle sealing data table according to the fabric structure data and the knitting machine needle data; the needle sealing data table includes invalid knitting needle data whose actions are prohibited;

[0068] An acquisition module 502 is used to acquire jacquard pattern data;

[0069] An expansion module 503 is used to expand the jacquard pattern data according to the sealing needle data table to obtain expanded pattern data;

[0070] The output module 504 is used to output the knitting needle motion data according to the unfolding pattern data and the needle closing data table.

[0071] In this embodiment, fabric structure data is obtained according to the regular characteristics of the fabric, and the fabric structure data reflects the way the knitting machine weaves the fabric. Then, a needle blocking data table is generated according to the knitting machine needle data inherent in the knitting machine, thereby obtaining a needle blocking data table with invalid needle data. The jacquard pattern data is expanded according to actual needs, so that the jacquard pattern data is expanded to form expanded pattern data that meets the weaving size of the fabric, and a needle blocking signal is inserted into the expanded pattern data according to the needle blocking data table or a needle blocking signal is output to the knitting machine, so that the knitting machine can block the needles according to the invalid needle data in the needle blocking data table when performing jacquard according to the expanded pattern data.
