Description

Technical Field

[0001] This invention relates to the field of incense technology, and in particular to a method for making incense containing gold powder. Background Technology

[0002] Incense sticks, as a traditional incense product, have a long history. In the early days, they were mainly made of natural fragrances and had functions such as purifying the air and calming the mind and aiding sleep. With the development of culture and craftsmanship, incense sticks have gradually incorporated art and symbolic meaning. For example, adding precious metal powders such as gold powder not only enhances the visual appeal (the ash has a golden luster when burned) but is also considered to have special cultural value.

[0003] Currently, incense sticks are mostly made by hand-extrusion and incense-pressing machines. Hand-extrusion relies on the skilled craftsmanship and rich experience of workers, giving the incense sticks a unique artistic style and delicate expression. However, hand-painting is inefficient, making it difficult to meet the needs of large-scale production, and it also requires extremely high levels of professional skills from workers, resulting in high labor costs.

[0004] While incense extrusion machines have significantly improved production efficiency, they also face serious challenges. Due to variations in the material ratio of the incense paste, cracks can appear in the incense sticks formed during the extrusion process. These cracks not only directly reduce the toughness of the incense sticks and disrupt the uniformity of their burning, but also detract from their aesthetic appearance and the user experience. Summary of the Invention

[0005] Therefore, the present invention provides a method for making incense sticks containing gold powder, in order to overcome the problem that the incense body formed by extrusion during the extrusion process of the incense extruder in the prior art is prone to cracking.

[0006] To achieve the above objectives, the present invention provides a method for producing incense sticks containing gold powder, comprising: Step S1: After mixing the nano gold powder with fragrance, binder and auxiliary components, add purified water and stir until uniform to obtain fragrance mud. Step S2: The incense paste is placed into an incense extruder and extruded using a pentagonal hole mold to complete the incense paste extrusion and forming into incense sticks; Step S3: Cameras are sequentially positioned above the mold outlet and the first gap along the direction of incense forming to obtain images of the incense sticks at two points. Step S4: In response to the presence of a crack in the image of the incense stick at the mold exit, a molding feature value is obtained based on the average change in the width of the crack in the images of the incense stick at the mold exit and at the first gap. Step S5: When it is initially determined that the molding of the incense stick does not meet the preset standard based on the molding characteristic value, the reason for not meeting the preset standard is further determined based on the extrusion characteristic value; and when it is initially determined that the molding of the incense stick meets the preset standard, whether it meets the preset standard is verified based on the planar deformation characteristic value. Step S6: In response to the absence of cracks in the image of the incense stick at the mold exit, or verification that the molding of the incense stick meets the preset standard, the incense stick is dried.

[0007] Furthermore, in step S5, in response to the molding characteristic value being less than a preset molding characteristic value, it is determined that the molding of the incense does not meet the preset standard; and in response to the molding characteristic value being greater than or equal to the preset molding characteristic value, it is determined that the molding of the incense meets the preset standard.

[0008] Furthermore, the forming characteristic value is the average of the rate of change of the width of the crack in several images of the incense stick at the mold exit and the width of the corresponding crack in the image of the incense stick at the first spacing.

[0009] Furthermore, based on the extrusion characteristic values, the reasons why the incense sticks do not meet the preset standards are further determined, wherein... If the extrusion characteristic value is less than the preset extrusion characteristic threshold, it is further determined that the reason why the incense stick does not meet the preset standard is that the extrusion speed is not up to standard, and the extrusion speed of the next batch of incense sticks is reduced according to the difference between the preset extrusion characteristic threshold and the extrusion characteristic value. If the extrusion characteristic value is greater than or equal to the preset extrusion characteristic threshold, the reason why the incense stick does not meet the preset standard is that the incense paste mixing time is not up to standard, and the mixing time of the next batch of incense paste is increased according to the difference between the extrusion characteristic value and the preset extrusion characteristic threshold.

[0010] Furthermore, the extrusion characteristic value is the ratio of the discharge expansion coefficient to the preset expansion coefficient, wherein the discharge expansion coefficient is the ratio of the cross-sectional area of ​​a single incense stick extrusion to the cross-sectional area of ​​the corresponding die opening.

[0011] Furthermore, the reduction in the extrusion speed of the next batch of incense sticks is positively correlated with the difference between the preset extrusion characteristic threshold and the extrusion characteristic value.

[0012] Furthermore, under the first preset condition, the extrusion speed of the next batch of incense sticks is corrected, and the correction range of the extrusion speed is positively correlated with the difference between the cross-sectional fluctuation value and the preset fluctuation value; the first preset condition is that the extrusion speed adjustment is completed and the cross-sectional fluctuation value of the adjusted incense sticks is greater than the preset fluctuation value.

[0013] Furthermore, the molding of the incense stick is checked against a preset standard based on the planar deformation characteristic value. If the planar deformation characteristic value is less than the preset planar deformation characteristic value, then the molding of the incense stick is verified to meet the preset standard, and the incense stick that meets the preset standard is dried. If the planar deformation characteristic value is greater than or equal to the planar deformation characteristic value, the molding of the incense stick is checked to ensure it does not meet the preset standard, and the amount of pure water added is reduced according to the difference between the planar deformation characteristic value and the preset planar deformation characteristic value.

[0014] The planar deformation characteristic value is the ratio of the cross-sectional height in the image of the incense stick at the mold exit to the cross-sectional height in the image of the incense stick at the first spacing.

[0015] Furthermore, the drying process employs a staged drying method.

[0016] Furthermore, the fragrance powder consists of nano-gold powder, fragrance, binder, and auxiliary components, wherein the fragrance is vanillin, the binder is elm bark powder, and the auxiliary components are charcoal powder; the mass ratio of the nano-gold powder, the fragrance, the binder, and the auxiliary components is 2:20:5:28.

[0017] Compared with existing technologies, the advantages of this invention are as follows: by arranging cameras at the mold exit and the first gap to acquire images of the incense sticks, and conducting detailed analysis of crack conditions, crack problems occurring during the incense stick forming process can be detected in a timely manner. Forming characteristic values ​​are obtained based on the average change in crack width, and this is used to determine whether the incense stick forming meets preset standards. This effectively avoids appearance defects caused by cracks, ensures the integrity and aesthetics of the incense stick product, and enhances the product's market competitiveness.

[0018] Furthermore, by using planar deformation characteristic values ​​to verify the incense stick forming process, the dimensional changes of the incense sticks during extrusion can be accurately monitored. When the planar deformation characteristic values ​​do not meet the preset standards, timely adjustment of the amount of purified water added helps to control the dimensional stability of the incense sticks, ensuring that each incense stick is of uniform size and improving the consistency of product quality.

[0019] Furthermore, when it is initially determined that the incense stick forming does not meet the preset standards, the reasons for non-compliance are further determined based on the extrusion characteristic values. By distinguishing between two situations—inadequate extrusion speed and inadequate incense paste mixing time—and taking corresponding adjustment measures, problems in the production process can be quickly located and resolved, reducing production downtime and improving production efficiency.

[0020] Furthermore, several speed reduction adjustment methods are set for the extrusion speed, each with a different adjustment range; under specific conditions, several correction methods are also set, with different correction ranges. This refined parameter adjustment method can make precise adjustments according to the actual situation, avoiding over-adjustment or under-adjustment, ensuring the stability and efficiency of the production process, and reducing production waste caused by inappropriate parameters.

[0021] Furthermore, the staged drying method effectively reduces the risk of incense sticks breaking due to uneven drying.

[0022] Furthermore, the specifications clearly define the mass ratio of nano-gold powder, fragrance, binder, and auxiliary components in the incense powder as 2:20:5:28. This precise raw material ratio, carefully designed and verified through practice, fully leverages the characteristics of each component, allowing the incense sticks to emit a unique aroma when burned. The addition of nano-gold powder not only enhances the visual appeal of the incense sticks but may also endow them with special effects or value, thus improving the product's quality and uniqueness.

[0023] This invention uses cameras placed at the mold exit and the first gap to dynamically capture images of cracks during the incense stick forming process. Combined with a preset crack degree threshold, it achieves real-time identification and classification of crack defects. This not only makes the incense sticks look more beautiful and neat, but also ensures the uniformity of the incense sticks' burning and makes the burning speed of the incense sticks more stable during use.

[0025] In order to make the objects and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with embodiments; it should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0027] Please see Figure 1-4 The following are flowcharts respectively: a flowchart of the method for making incense sticks containing gold powder according to an embodiment of the present invention; a schematic diagram of the pentagonal hole mold structure according to an embodiment of the present invention; a flowchart of the method for initially determining whether the molding of the incense sticks meets the preset standard based on the molding characteristic value according to an embodiment of the present invention; and a flowchart of the method for further determining the reasons why the molding of the incense sticks does not meet the preset standard based on the extrusion characteristic value according to an embodiment of the present invention.

[0028] An embodiment of the present invention provides a method for making incense sticks containing gold powder, comprising: Step S1: After mixing the nano gold powder with fragrance, binder and auxiliary components, add purified water and stir until uniform to obtain fragrance mud. Step S2: The incense paste is placed into an incense extruder and extruded using a pentagonal hole mold 2 to complete the incense paste extrusion and forming to obtain incense sticks 1; Step S3: Cameras are sequentially arranged at the mold outlet 3 and the first gap along the top of the incense forming direction to obtain images of the incense stick 1 at two points. Step S4: In response to the presence of a crack in the image of the incense stick 1 at the mold exit 3, a molding feature value is obtained based on the average change in the width of the crack in the images of the incense stick 1 at the mold exit 3 and the first gap. Step S5: When it is initially determined that the molding of the incense stick 1 does not meet the preset standard based on the molding characteristic value, the reason for not meeting the preset standard is further determined based on the extrusion characteristic value; and when it is initially determined that the molding of the incense stick 1 meets the preset standard, whether it meets the preset standard is verified based on the planar deformation characteristic value. Step S6: In response to the absence of cracks in the image of the incense stick 1 at the mold outlet 3, or verification that the molding of the incense stick 1 meets the preset standard, the incense stick 1 is dried.

[0029] Specifically, the fragrance powder consists of nano-gold powder, fragrance, binder, and auxiliary components, wherein the fragrance is vanillin, the binder is elm bark powder, and the auxiliary components are charcoal powder; the mass ratio of the nano-gold powder, the fragrance, the binder, and the auxiliary components is 2:20:5:28.

[0030] Specifically, the ratio of incense powder to purified water is 1:0.7, that is, 70 ml of purified water is added for every 100 grams of incense powder.

[0031] Specifically, the mixing process requires continuous kneading for 10-15 minutes, and repeated folding to ensure even distribution of moisture.

[0032] Specifically, the pentagonal hole mold 2 has a specific shape in Figure 2 As shown in the image.

[0033] Specifically, cameras such as Dahua DH-IPC-HFW8443H-Z-V2 are arranged sequentially above the mold outlet 3 and the first spacing point directly above the fragrance forming direction. The specific cameras are not limited, as long as they can output corresponding image results based on the input data.

[0034] Specifically, the crack is defined as the width of the crack in the image when the width of the crack is greater than 0.1 mm and the length of the crack is greater than 0.5 mm.

[0035] Specifically, in step S5, in response to the molding characteristic value being less than a preset molding characteristic value, it is determined that the molding of the incense stick 1 does not meet the preset standard, and in response to the molding characteristic value being greater than or equal to the preset molding characteristic value, it is determined that the molding of the incense stick 1 meets the preset standard.

[0036] Specifically, the forming characteristic value is the average rate of change between the width of the crack in several images of the incense stick 1 at the mold exit 3 and the width of the corresponding crack in the image of the incense stick 1 at the first spacing. The preset forming characteristic value is set to 1.00. It should be noted that the data in this embodiment are all results obtained through preliminary experiments before the system was run. Each preset value can be adjusted according to the specific usage, as long as the system method of this invention can clearly define different specific situations in the single-item judgment process through the acquired values.

[0037] The preset molding characteristic values ​​have been verified by a large amount of experimental data and can effectively reflect the stability and integrity of incense stick 1 during the extrusion process. When the average change in crack width exceeds this threshold, it indicates that the molding quality of incense stick 1 may be affected by the material ratio or process parameters. In addition, the judgment and handling mechanism for crack problems adopts multi-level logic to ensure that the quality of each batch of incense stick 1 is controllable. Specifically, based on the extrusion characteristic value, the reason why the molding of incense stick 1 does not meet the preset standard is determined, wherein... If the extrusion characteristic value is less than the preset extrusion characteristic threshold, it is further determined that the reason why the molding of incense stick 1 does not meet the preset standard is that the extrusion speed is not up to standard, and the extrusion speed of the next batch of incense stick 1 is reduced according to the difference between the preset extrusion characteristic threshold and the extrusion characteristic value. If the extrusion characteristic value is greater than or equal to the preset extrusion characteristic threshold, it is further determined that the reason why the molding of incense stick 1 does not meet the preset standard is that the incense paste stirring time is not up to standard. The stirring time of the next batch of incense paste is increased according to the difference between the extrusion characteristic value and the preset extrusion characteristic threshold. The preset extrusion characteristic threshold is set to 1.2.

[0038] Specifically, when determining whether the molding of incense stick 1 meets the standards, in addition to considering the variation in crack width, the smoothness of the incense stick 1 surface and the uniformity of the cross-section are also taken into account. These indicators are quantified using image analysis algorithms, thereby providing more comprehensive data support for the calculation of molding characteristic values. At the same time, to improve the accuracy of the determination, the system automatically records the image data of each incense stick 1 and generates a corresponding quality report, which facilitates subsequent traceability and optimization.

[0039] Specifically, the extrusion characteristic value is the ratio of the discharge expansion coefficient to the preset expansion coefficient, where the discharge expansion coefficient is the ratio of the extruded cross-sectional area of ​​a single incense stick 1 to the cross-sectional area of ​​the corresponding die opening. The preset expansion coefficient is set based on the design parameters of different die openings and the physical properties of the incense stick 1 material. Experimental verification shows that when the ratio of the discharge expansion coefficient to the preset expansion coefficient deviates from a reasonable range, it indicates that there may be uneven pressure distribution or abnormal material flowability during the extrusion process of the incense stick 1. In this case, the system will automatically adjust the relevant process parameters according to the specific deviation of the extrusion characteristic value to ensure the consistency and stability of the incense stick 1 molding.

[0040] Specifically, the reduction in the extrusion speed of the next batch of incense sticks is positively correlated with the difference between the preset extrusion characteristic threshold and the extrusion characteristic value. It is understood that this positive correlation can be linear or nonlinear, and is not specifically limited. The slope of the linear positive correlation is also not specifically limited and can be set according to the actual preparation conditions, as long as the larger the difference between the preset extrusion characteristic threshold and the extrusion characteristic value, the greater the reduction in extrusion speed. For example, if the reduction in extrusion speed is set to ΔV, and the difference between the preset extrusion characteristic threshold and the extrusion characteristic value is set to ΔΦ, then ΔV = α × ΔΦ, where α is the speed adjustment coefficient, and α = 1.03.

[0041] Specifically, under a first preset condition, the extrusion speed of the next batch of incense sticks is corrected, and the correction range of the extrusion speed is positively correlated with the difference between the cross-sectional fluctuation value and the preset fluctuation value. The first preset condition is that the extrusion speed adjustment is completed and the cross-sectional fluctuation value of the adjusted incense stick output is greater than the preset fluctuation value. The cross-sectional fluctuation value is the average of the ratios of the maximum area value to the minimum area value among several unit lengths of the incense stick, and the preset fluctuation value is 0.04. It is understood that the positive correlation can be linear or nonlinear, and is not specifically limited. The slope of the linear positive correlation is also not specifically limited and can be set according to the actual preparation conditions, as long as the difference between the cross-sectional fluctuation value and the preset fluctuation value is larger, the correction range of the extrusion speed is larger. For example, if the correction range of the extrusion speed is set to ΔR, and the difference between the cross-sectional fluctuation value and the preset fluctuation value is set to Δγ, then ΔR = β × Δγ, where β is the speed correction adjustment coefficient, and β = 1.01.

[0042] Specifically, the molding of the incense stick 1 is checked against a preset standard based on the planar deformation characteristic value. If the planar deformation characteristic value is less than the preset planar deformation characteristic value, then the molding of the incense stick 1 is verified to meet the preset standard, and the incense stick 1 that meets the preset standard is dried. If the planar deformation characteristic value is greater than or equal to the planar deformation characteristic value, the molding of the incense stick 1 is checked to be inconsistent with the preset standard, and the amount of pure water added is reduced according to the difference between the planar deformation characteristic value and the preset planar deformation characteristic value.

[0043] The planar deformation characteristic value is the ratio of the cross-sectional height in the image of the incense stick 1 at the mold outlet 3 to the cross-sectional height in the image of the incense stick 1 at the first spacing.

[0044] Specifically, the preset planar deformation characteristic value is set to 0.8.

[0045] Specifically, the calculation of the planar deformation characteristic value not only considers the changes in the cross-sectional height of the incense stick 1 at the mold exit point 3 and the first spacing, but also incorporates the surface flatness data of the incense stick 1. By introducing multi-dimensional measurement indicators, the morphological changes of the incense stick 1 during the extrusion process can be more comprehensively reflected. When the planar deformation characteristic value does not meet the preset standard, the system will reduce the amount of pure water added according to the specific deviation value, usually by 2%-5% of the total added amount each time, in order to gradually optimize the molding quality of the incense stick 1.

[0046] Specifically, the drying process employs a staged drying method. This method consists of three stages: the first stage uses low-temperature, slow drying, with the temperature controlled between 30℃ and 35℃, lasting for 2 hours; the second stage gradually increases the temperature to 40℃-45℃, lasting for 3 hours; and the third stage maintains a constant temperature of 45℃ until the incense stick is completely dry. This method effectively avoids cracking of the incense stick due to sudden temperature changes, while ensuring uniform evaporation of moisture from the incense stick, thereby improving the overall quality of the product.

[0047] Specifically, the fragrance mud consists of nano-gold powder, fragrance, binder, and auxiliary components, wherein the fragrance is vanillin, the binder is elm bark powder, and the auxiliary components are charcoal powder; the mass ratio of the nano-gold powder, the fragrance, the binder, and the auxiliary components is 2:20:5:28.

[0048] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions resulting from these changes or substitutions will all fall within the scope of protection of the present invention. The above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention; for those skilled in the art, the present invention can have various modifications and variations.
