It should be noted that the descriptions of "first", "second", etc. in this article are used to distinguish different messages, devices, modules, etc., and do not represent the order of precedence, nor do they limit "first" and "second" to be different types.

[0084] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0085] The acetate fiber production line includes various raw material storage tanks, filters, storage tanks, degassing tanks, spinning machines, yarn bundling devices, crimpers, conveyors, multi-channel conveying swing bucket mechanisms, dryers and swinging yarn machines; the raw material storage tanks, dissolving tanks, filters, storage tanks, degassing tanks and spinning machines are connected in sequence, and the spinning machine is connected to the crimper through the yarn bundling device; the crimper is connected to the multi-channel conveying swing bucket mechanism; the multi-channel conveying swing bucket mechanism is connected to the dryer front and back and is located above the dryer; the swinging yarn machine is connected to the dryer.

[0086] In the existing technology, acetate fiber production lines are capable of producing acetate fiber with high efficiency and high quality. Through the reasonable configuration of various equipment, especially the design of the return air supply device in the tunnel, the yarn bundling device and the multi-channel conveying swing bucket device, various defects that affect product quality are eliminated, ensuring high-efficiency, stable and reliable production and the quality of the yarn. However, in the existing technology, if the number of production lines has been determined, it cannot be modified, which greatly limits the production capacity level of the generated products.

[0087] In one embodiment of the present invention, a flexible production method and system for diacetate fiber are provided. This solution provides a flexible acetate fiber production process and, through a dovetail roller layout and high-speed curved tow placement technology, enables the addition of multiple production lines, increasing product production capacity by 50% within a limited space.

[0088] According to a first aspect of an embodiment of the present invention, a flexible production method for diacetate fiber is provided.

[0089] Figure 1 The present invention is a flowchart of a flexible production method of diacetate fiber according to an embodiment of the present invention.

[0090] In one or more embodiments, preferably, the flexible production method of diacetate fiber includes:

[0091] S101, setting an improved spinning machine structure to adapt to online updating of the number of wires;

[0092] S102, setting a switching process between four-thread and five-thread according to the improved spinning machine structure;

[0093] S103, setting a switching process between four-line and three-line according to the improved spinning machine structure;

[0094] S104, setting a switching process of four lines, five lines and six lines according to the improved spinning machine structure;

[0095] S105: Obtain the current spinning machine's line change requirements and perform online switching according to the line change requirements;

[0096] S106: After the online switching is completed, the system interface after the line change is displayed.

[0097] In the embodiment of the present invention, when converting from four to five (five to six) or four to three, it is necessary to replace the Crotti rollers of different widths to adapt to the production of the new specifications. The width of the Crotti rollers produced by the five-line and six-line production is 17-20 mm, and the width of the Crotti rollers produced by the three-line production is 25-30 mm. Therefore, it is necessary to set preset Crotti rollers of different widths in advance to adapt to online replacement.

[0098] Figure 2The present invention is a flowchart of an improved spinning machine structure in a flexible production method of diacetate fiber in one embodiment of the present invention, which is used to adapt to online updating of the number of lines.

[0099] like Figure 2 As shown, in one or more embodiments, preferably, the improved spinning machine structure is configured to adapt to online updating of the number of lines, specifically including:

[0100] S201, under the four-line system, set each line to have 31-35 corridors;

[0101] S202. Under the five-line system, set each line to have 24-28 corridors;

[0102] S203. Under the six-line system, each line is set to have 20-24 corridors.

[0103] S204, equip each line with 1-3 thread repair guns;

[0104] S205, setting the height of the spinning machine Crotti roller fixed groove to be 1-3 cm lower than the original height;

[0105] S206. Set different widths of Crotti rollers to adapt to the production of new specifications. The width of Crotti rollers produced on the fifth and sixth lines is 17-20 mm, and the width of Crotti rollers produced on the third line is 25-30 mm.

[0106] S207, the gap between the climbing rollers of the partitions along the spinning machine is set to a preset width;

[0107] S208. When setting the climbing rollers at the air suction port of the spinning machine, one more set of rollers is required when the number of rollers is changed from four to five, and another set of rollers is required when the number of rollers is changed from five to six. The dovetail groove uses a 12-15 groove mode, and 1-3 climbing rollers used on the same line are installed with an interval of 1-3 grooves.

[0108] In an embodiment of the present invention, to adapt to the flexible production control of current spinning machines, the configuration and adjustment of the spinning machine are described. The details are as follows: First, in a four-thread system, each line has 31-35 channels; in a five-thread system, each line has 24-28 channels; and in a six-thread system, each line has 20-24 channels. These are different spinning machine configurations, and the appropriate thread system is selected based on production requirements. Second, each line is equipped with 1-3 yarn feeders, which are devices used to replenish yarn on the spinning machine. Furthermore, the height of the spinning machine's crotir roller fixing slot is lowered by 1-3 cm. This is an adjustment to a spinning machine component to accommodate new production specifications. Furthermore, crotir rollers of different widths are configured to accommodate new production specifications: 17-20 mm for five- and six-thread production, and 25-30 mm for three-thread production. This involves adjusting another component on the spinning machine to accommodate switching between different production methods. The gaps between the climbing rollers on the partitions along the spinning machine line are set to a preset width. This involves adjusting a component on the spinning machine to meet production requirements. When switching from a four-speed to a five-speed system, an additional set of climbing rollers is required at the spinning machine's suction port. When switching from a five-speed to a six-speed system, another set is required. The dovetail grooves use a 12-15-slot pattern, and the 1-3 climbing rollers used on the same line are installed 1-3 slots apart. This involves adjusting a component on the spinning machine to accommodate the transition between different thread systems.

[0109] Figure 3 It is a flow chart of a switching process of setting four lines and five lines according to the improved spinning machine structure in a flexible production method of diacetate fiber according to one embodiment of the present invention.

[0110] like Figure 3 As shown, in one or more embodiments, preferably, the switching process of setting four-line and five-line according to the improved spinning machine structure specifically includes:

[0111] S301, setting the control interface of the spinning machine to include at least a 4-line mode and a 5-line mode;

[0112] S302. After clicking the spinning machine selection button, a dialog box pops up to select the current mode as either a four-wire system or a five-wire system;

[0113] S303, when in the four / five-wire system state, the button corresponding to the current four / five-wire system is in an unselectable state;

[0114] S304. If the user clicks on a switchable line mode, a secondary confirmation box pops up to determine whether the operation is an error. If not, the system continues to switch to another line mode. If not, no action is taken.

[0115] S305. When starting the wire system switching, determine whether the switching task meets the first preset condition. The first preset condition includes switching the unused thread repair gun to a parking state before switching from the 5-wire system to the 4-wire system to prevent it from generating additional meaningless alarms. When switching from the 5-wire system to the 4-wire system, one of the thread repair guns in the 5-wire system is not used.

[0116] S306: In the 4-wire system, the No. 2 wire repair gun is not put into use, and the relevant wire break alarm information is displayed;

[0117] S307. Under the 5-line system, 5 thread-repairing guns are put into use, and 27-30 corridors are set for each line.

[0118] Figure 4 It is a flow chart of a switching process of setting four lines and three lines according to the improved spinning machine structure in a flexible production method of diacetate fiber according to one embodiment of the present invention.

[0119] like Figure 4 As shown, in one or more embodiments, preferably, the switching process between four-line and three-line according to the improved spinning machine structure is specifically provided including:

[0120] S401, setting the control interface of the spinning machine to include at least a four-line mode and a three-line mode;

[0121] S402. After clicking the spinning machine selection button, a dialog box pops up for selecting the current mode as a four-wire system or a three-wire system;

[0122] S403, when in the four-wire / three-wire system state, the button corresponding to the current four-wire / three-wire system is in an unselectable state;

[0123] S404. If the user clicks on a switchable line mode, a secondary confirmation box pops up to determine whether the operation is an error. If not, the system continues to switch. If not, no action is taken.

[0124] S405, when starting the wire system switching, determining whether the switching task meets a second preset condition, wherein the second preset condition includes switching the soon-to-be-unused thread gun to a parking state before switching from the four-wire system to the three-wire system;

[0125] S406: In the three-wire system, the No. 2 thread mending gun is not used. Each line has 46-50 corridors, and the wire is mended for each line, and the wire break alarm information is displayed;

[0126] S407, Under the four-line system, four thread-filling guns are put into use, and each line has 34-38 corridors.

[0127] Figure 5It is a flow chart of a switching process of setting four lines, five lines and six lines according to the improved spinning machine structure in a flexible production method of diacetate fiber according to one embodiment of the present invention.

[0128] like Figure 5 As shown, in one or more embodiments, preferably, the switching process of setting four lines, five lines and six lines according to the improved spinning machine structure specifically includes:

[0129] S501, setting the control interface of the spinning machine to include at least four-line mode, five-line mode and six-line mode;

[0130] S502. After clicking the spinning machine selection button, a dialog box pops up for selecting the current mode as one of the four-wire system, the five-wire system, or the six-wire system;

[0131] S503, when in the four-wire, five-wire or six-wire state, the button corresponding to the current four-wire, five-wire or six-wire system is in an unselectable state;

[0132] S504. If the user clicks on a switchable line mode, a secondary confirmation box pops up to determine whether the operation is an error. If not, the line mode switching continues. If not, no action is taken.

[0133] S505. When starting the wire system switching, determine whether the switching task meets the third preset condition. The third preset condition includes that before switching to the four-wire system, two of the wire repair guns must be switched to the parking state, and before switching to the five-wire system, one of the wire repair guns must be switched to the parking state.

[0134] Figure 6 This is a flowchart of obtaining the current line change demand of a spinning machine and performing online switching according to the line change demand in a flexible production method of diacetate fiber according to one embodiment of the present invention.

[0135] like Figure 6 As shown, in one or more embodiments, preferably, obtaining the current line change demand of the spinning machine and performing online switching according to the line change demand specifically includes:

[0136] S601, obtaining the current line change demand online, determining whether it is a switch between four lines, five lines, or six lines, and switching to the preset first screen;

[0137] S602, determining whether the current line change requirement is a switch between four lines and five lines, and if so, switching to the preset second screen;

[0138] S603: Determine whether the current line change requirement is a switch between four lines and three lines. If it is, switch to the preset third screen.

[0139] In an embodiment of the present invention, the implementation steps include obtaining the current line change demand online, judging whether it belongs to the switch between four lines, five lines and six lines, and switching to the preset first screen; then further judging whether it belongs to the switch between four lines and five lines or the switch between four lines and three lines according to the specific needs, and switching to the preset second screen or third screen respectively. The line system of the spinning machine (such as four lines, five lines and six lines) directly affects the production capacity and product diversity. Therefore, the ability to quickly and accurately switch the line system configuration of the production line is of great significance to meeting market demand. The specific process includes: Determining the line change demand: First, the current line change demand needs to be input through the system interface or console. This step is usually completed by the operator according to the requirements of the production plan. The system needs to be able to recognize different line system requirements, such as four lines, five lines or six lines, and automatically perform preliminary screen switching according to these requirements. Switching screen: After confirming that the line system needs to be switched, the system first switches to a preset basic screen, which usually contains the basic settings and parameters of all possible line systems involved. Refining the specific switch: If the switch is confirmed to be between four and five lines, the system will switch to another preset screen, which is specifically configured for the specific needs of these two line systems. Handling special switches: If the switch is a special switch between four and three lines, it is necessary to switch to another dedicated screen to handle it. This switch is relatively rare and usually involves larger structural adjustments and parameter changes. Confirming the adjustment is complete: After each screen switch and parameter adjustment, the system's test function needs to verify the new configuration is correct to ensure the smooth operation of the production line.

[0140] Figure 7 The present invention is a flowchart of a system interface display after completing online switching in a flexible production method of diacetate fiber according to an embodiment of the present invention.

[0141] like Figure 7 As shown, in one or more embodiments, preferably, after completing the online switching, the system interface display after the line change specifically includes:

[0142] S701. After the screen switching is completed, the online line system is selected, and then one of the switching processes of four lines and five lines, four lines and three lines, and four lines, five lines and six lines is selected;

[0143] S702. During the line change process, the current line status and operation status are automatically displayed, and abnormal status is prompted.
