DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0043] In addition, in the description of the present specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0044] References to "one embodiment" or "some embodiments" etc. described in the present specification mean that one or more embodiments of the present invention include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0045] See also Figure 1-2 The present application proposes a weighing, mixing and dispensing system for large amounts of dyes, comprising: a mixing machine 1, a moving track 2, a large material box 3, a medium material box 4 and a small material box 5, wherein the moving track 2 is used to drive the mixing machine 1 to move, and the large material box 3, the medium material box 4 and the small material box 5 all convey powdered dyes to the mixing machine 1 through a spiral feeding device 21, and after the mixing is completed, the dye solution in the mixing machine 1 is conveyed to the auxiliary cylinder of the dyeing machine;

[0046] A first weighing module 6 is disposed below the material processing machine 1 , a second weighing module 7 is disposed below the medium material box 4 , and a third weighing module 8 is disposed below the small material box 5 .

[0047] A medium- and small-amount dye material box with a weighing module is designed, and the weight loss method is used to measure the medium- and small-amount dyes, solving the problem that the large-amount dye system cannot measure the medium- and small-amount dyes due to accuracy issues;

[0048] The powder dye is loaded into the material box through the negative pressure device 19, and discharged into the material mixing machine 1 through the spiral. After the weighing module is weighed, the material mixing begins. After the material mixing is completed, the delivery pump transports the dye solution to the auxiliary cylinder of the designated dyeing machine.

[0049] The large-volume quantitative feeding system includes a large-capacity feeder 1, which is equipped with multiple large material boxes 3, medium material boxes 4 and small material boxes 5. Three weighing modules are designed on the large-volume quantitative feeder 1. The large material box 3 has no weighing module, and each of the medium material box 4 and the small material box 5 has a weighing module. When there are large, medium and small amounts of dyes in a multi-branch order, the feeder 1 automatically moves to the position of the small material box 5. Since the small material box 5 has a weighing module, the weight of the material is measured by the weight loss method; when the small amount of dye is weighed, the feeder 1 automatically moves to the position of the medium material box 4, and the dye is weighed by the same weight loss method as the small material box 5; when the medium amount of dye is weighed, the feeder 1 automatically moves to the position of the large material box 3. Since the large material box 3 has no weighing module, the large-volume quantitative feeder 1 has a weighing module, so the weighing is completed on the feeder 1, and the weight of the material is measured by the weighting method.

[0050] Conventional large-volume quantitative material systems can only weigh large amounts of dyes. For medium and small amounts of dyes, due to the large range of the weighing module of the material machine 1, when weighing medium and small amounts of dyes, the weighing error is too large, resulting in the inability to make orders that require trace color adjustment. The large-volume quantitative material system of the present application can form various color matching schemes by combining large, medium and small material boxes, and has a wide range of applications.

[0051] This system can achieve fast weighing through the large material box 3 and accurate weighing through the small material box 5, solving the problem that conventional weighing equipment cannot balance weighing speed and accuracy.

[0052] Optionally, the material boxes include three specifications of 1500L, 200L and 60L. Each material box includes a vacuum negative pressure loading device, a spiral unloading device 21, a positive pressure blowing device 20, etc. The small and medium material boxes 5 are equipped with independent weighing modules to achieve better weighing accuracy.

[0053] Preferably, the system is data-interconnected with the ERP system and the dyeing machine central control system, obtains dye formula data from the ERP system, obtains delivery instructions from the dyeing machine central control system, and realizes networking, data exchange and joint control of the three systems.

[0054] It should be noted that characteristic process parameters of dye chemical materials are set for each dye, such as chemical material temperature, ease of dissolution, chemical material-water ratio, and solution expansion coefficient.

[0055] In some embodiments, the water volume calculation of the material mixer 1 includes a weight water ratio accumulation method or a heaviest water ratio method;

[0056] The calculation method of the amount of water in the chemical feed using the weight-water ratio accumulation method is as follows:

[0057] Where Q represents the amount of water used to make the material, in liters; i represents the i-th delivery order; j represents the j-th material in the same delivery order; W ij Indicates the weight of each dye, P ij Indicates the chemical-water ratio parameter of each dye. The chemical-water ratio parameter refers to the ratio or proportional coefficient of the amount of water required for each dye to its weight during the dye chemical process. This parameter is used to determine how much water needs to be added during chemical chemical process in order to fully dissolve and mix the dye to the appropriate concentration. In practical applications, the chemical-water ratio parameter may be determined based on a variety of factors such as the type, properties, required concentration, and production process requirements of the dye. Through this parameter, the amount of water in the chemical chemical process can be accurately controlled to ensure that the dye can be evenly and stably dissolved in water, thereby obtaining a dye solution that meets the requirements.

[0058] The calculation method of the amount of water in the heaviest water ratio method is as follows:

[0059]

[0060] Where Max(W ij ) represents the heaviest dye in an order, f(P ij |Max(W ij The )) function represents the chemical-to-water ratio corresponding to the heaviest dye among multiple dyes in an order.

[0061] f(P ij|Max(Wi j)) is the function for finding the maximum value. For example, in a delivery order, dye A weighs 100 grams and has a water ratio of 1:3; dye B weighs 2000 grams and has a water ratio of 1:3.5; dye C weighs 18000 grams and has a water ratio of 1:4. The maximum weight corresponds to dye C, which has a water ratio of 4, and the function value is 4.

[0062] In some embodiments, the calculation method of the material temperature of the material mixer 1 includes:

[0063] (1)T i =Max(T ij )

[0064] Where T i represents the temperature of the chemical used in the i-th delivery order, Max(T ij ) represents the chemical temperature of the dye with the highest chemical temperature in the i-th order;

[0065] or (2) T i =f(T ij |Max(W ij ))

[0066] Where Max(W ij ) represents the heaviest dye in the i-th order, f(T ij |Max(W ij )) function represents the chemical temperature corresponding to the heaviest dye among multiple dyes in the i-th order;

[0067] or (3)

[0068] Where W ij represents the weight of the jth dye in the ith order, T ij Indicates the chemical temperature corresponding to the jth dye in the ith order.

[0069] The weighted average method can more accurately control the temperature in the dyeing process, which helps to improve the uniformity and quality of dyeing. This method provides flexibility and can be adjusted according to the weight and temperature of different dyes in the order. Through accurate calculation, it is possible to avoid using too high or too low a temperature, thus saving energy. In addition, this method is suitable for a variety of dye combinations with different weight and temperature requirements, which improves the adaptability and flexibility of the system.

[0070] In some embodiments, the medium material box 4 and the small material box 5 use a weight loss method to measure the weight of the unloaded materials, and the large material box 3 uses a weight gain method to measure the weight of the unloaded materials.

[0071] The weight loss method determines the weight of the material by measuring the reduction in the weight of the dye in the material box. This method can provide higher weighing accuracy and is especially suitable for the precise weighing of small and medium amounts of dyes.

[0072] The weight-increase method determines the weight of the material by measuring the total weight of the dye after the material machine 1 receives the dye. This method is suitable for rapid and large-scale weighing, which improves production efficiency. For a large amount of dye in the large material box 3, the weight-increase method can complete the weighing in a short time, which is suitable for large-scale production needs.

[0073] In some embodiments, the weight loss method includes: the original weight of the dye in the material box is M1, after the dye is transported to the chemical machine 1, the weight of the remaining dye in the material box and the material box is M2, and the weight of the dye transported to the chemical machine 1 is M1-M2; this is equivalent to the weight value of the weighing module decreasing during the weighing process.

[0074] The weight-increasing method includes: the original weight of the chemical feeder 1 is M1, after the dye is transported to the chemical feeder 1, the weight of the chemical feeder 1 and the dye is M2, and the weight of the dye transported to the chemical feeder 1 is M2-M1. This is equivalent to the weight value of the weighing module increasing during the weighing process.

[0075] like Figure 3 As shown, in some embodiments, the material mixer 1 is connected to a stirring device 9 and a circulating pump 10;

[0076] The stirring device 9 can perform positive stirring and reverse stirring;

[0077] The circulation pump 10 is connected to a forward circulation valve 11 and a reverse circulation valve 12 respectively, and the forward circulation valve 11 and the reverse circulation valve 12 are connected to two sides of the material processing machine 1 through pipelines respectively.

[0078] The chemical machine 1 is designed with four states of pump circulation loop: no circulation, forward circulation, reverse circulation, double half-circle circulation (such as Figure 4 As shown in the figure, three stirring cycles are designed: no stirring, forward stirring, and reverse stirring. Through the combination of pump cycle and stirring cycle, the material mixer 1 can switch back and forth between 11 stirring modes, so that the most difficult rotation center position is continuously shifted, leaving no dead zone for stirring, and stirring more evenly, thereby reducing the stirring time and achieving the effect of rapid stirring.

[0079] The cone bottom part of the chemical feeder 1 is connected to the pump inlet through a pipeline. The pump outlet is divided into two and connected to two return pipes. The chemical feeder 1 enters the chemical feeder 1 from two sides. Each branch has a valve for switch control. The pump circulation loop can help the chemical feeder 1 to chemically feed the dye. The chemical feeder 1 can turn on the stirring device 9 to chemically feed and the internal circulation chemically feed at the same time. The circulation pump 10 switches to the internal circulation mode through the valve, and a forward rotation cycle, a reverse rotation cycle, and a double half-circle cycle will be formed in the chemical feeder 1. Optionally, a set of impeller agitators are designed in the chemical feeder 1 to achieve forward stirring and reverse stirring. The combination of the circulation pump 10 and the stirring device 9 can produce 11 chemical feeding methods. Their combinations are shown in Table 1:

[0080] Table 1

[0081]

[0082]

[0083] When the dye is dissolved, if there is only one dissolving method, a fixed rotation center point will be formed in the dissolving machine 1. Due to the slow water flow rate at the center point, it is difficult for the dye to be fully dissolved. The dissolving machine 1 of the present application can automatically switch between 11 dissolving methods during the dissolving process, so that the rotation center position of the solution is continuously shifted, and no dead zone of dye dissolution is generated. The dissolving is more uniform and sufficient, which can save dissolving time and achieve better dissolving effect.

[0084] like Figure 5 As shown, in some embodiments, the large material box 3, the medium material box 4 and the small material box 5 are all connected with a discharge pipe 13 and a telescopic driving member 14, the output end of the telescopic driving member 14 is connected with a driving rod 15, a limiting ring 16 is provided on the discharge pipe 13, the driving rod 15 passes through the limiting ring 16 and is connected with a discharge cover 17, and the discharge cover 17 is connected with the outlet cover of the discharge pipe 13.

[0085] The design of the discharge pipe 13 and the telescopic drive member 14 of the large material box 3, the medium material box 4 and the small material box 5 in the present invention provides an efficient, accurate and easy-to-operate dye delivery solution. The drive rod 15 connected to the output end of the telescopic drive member 14 can quickly and accurately control the opening and closing of the discharge cover 17 to ensure the accurate discharge of the dye, which not only simplifies the operation process, but also improves production efficiency and safety. The close fit between the discharge cover 17 and the discharge pipe 13 reduces dust overflow and keeps the working environment clean, while also reducing material waste and improving material utilization. In addition, the use of the limit ring 16 ensures the correct position of the discharge cover 17, making the entire discharge mechanism compact and saving space. The easy-to-maintain design also reduces the cost of long-term operation. Overall, this design improves the flexibility and adaptability of production, can meet different production needs, and at the same time brings economic benefits to the enterprise by reducing material waste and improving production efficiency.

[0086] In some embodiments, Figure 5 As shown, the discharge pipe 13 is connected to a moisture removal device (not shown) via an air nozzle 18 .

[0087] In order to prevent the dye from caking at the discharge port due to the moisture of warm water invading the discharge port when weighing the dye, a moisture-removing device is designed on the side of the discharge pipe 13 of the material box to keep the discharge port free of caking, make the feeding speed easier to control, and make the weighing more accurate.

[0088] like Figure 6 As shown, in some embodiments, the large material box 3, the medium material box 4 and the small material box 5 all load the powder dye through a negative pressure device 19, and the side walls of the large material box 3, the medium material box 4 and the small material box 5 are provided with multiple positive pressure blowing devices 20 from top to bottom.

[0089] All the material boxes are equipped with multiple air nozzles 18 above and below, and each air nozzle 18 is controlled by a solenoid valve alone. In this way, the positive pressure blowing of the solenoid valve can be controlled in multiple directions to prevent the powder dye in the material box 4 from forming cavities when the material is dropped during the weighing process, and ensure smooth and continuous material dropping. Each discharge pipe 13 is also equipped with air nozzles 18 controlled by a separate solenoid valve on both sides. The positive pressure blowing prevents the water vapor in the material machine 1 from flowing back into the material box when the material is dropped, and prevents the dye in the material box and the discharge port from agglomerating, so that the material dropping speed can be precisely controlled without exceeding the tolerance, and accurate weighing can be achieved.

[0090] like Figure 6 As shown, in some embodiments, the spiral feeding device 21 includes a feeding motor 2101, a feeding tube 2102, a pitch-variable screw 2103, an opening cylinder 2104 and a discharge cover 17, the pitch-variable screw 2103 is arranged in the feeding tube 2102, the output end of the feeding motor 2101 is connected to the pitch-variable screw 2103, the output section of the opening cylinder 2104 is connected to the discharge cover 17, and the discharge cover 17 is connected to the outlet cover of the feeding tube 2102.

[0091] The spiral feeding device 21 incorporates a variety of sophisticated mechanical components to achieve efficient, controllable and stable powder dye delivery. The direct drive pitch variable screw 2103 of the feeding motor 2101 ensures the efficiency and stability of power transmission and provides a strong power guarantee for the feeding process. The design of the pitch variable screw 2103 allows the screw to have different pitches at different positions, which means that the conveying efficiency of the screw can be adjusted according to the material characteristics and feeding speed requirements, thereby achieving fine control of the feeding process.

[0092] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
