[0028] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0029] As used herein, the term "including" and its variations represent open inclusion, i.e., "including but not limited to." Unless otherwise stated, the term "or" means "and / or." The term "based on" means "based at least in part on." The terms "an example embodiment" and "an embodiment" mean "at least one example embodiment." The term "another embodiment" means "at least one additional embodiment." The terms "first," "second," etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0030] As previously described, dyeing processes can be used to color fabrics (e.g., textiles). Traditional dyeing processes typically involve dyeing the fabric using dyeing equipment and then performing a color development process on the dyed fabric using a cold-batch process. This development process typically takes more than 12 hours, which is time-consuming and prolongs the fabric production cycle.

[0031] To at least partially address one or more of the aforementioned and other potential issues, exemplary embodiments of the present disclosure provide a spray coating solution, wherein a spray coating system includes a spraying device, a reeling device, a penetrating device, and a coloring device. The spraying device is configured to spray a target liquid onto a target object; the reeling device is disposed downstream of the spraying device and is configured to reel the sprayed target object; the penetrating device is configured to rotate the reeled target object at a predetermined rotational speed for a first predetermined period to allow the target liquid to penetrate the target object; and the coloring device is configured to maintain the infiltrated target object at a first predetermined temperature for a second predetermined period to allow coloring. Consequently, the time required to color the target object can be significantly reduced, thereby improving production efficiency.

[0032] Figure 1 A schematic diagram of a spraying system 100 according to an embodiment of the present disclosure is shown from a first perspective. Figure 2 A schematic diagram of a second perspective view of a portion of a spray coating system 100 according to an embodiment of the present disclosure is shown. For ease of illustration, arrows are used to indicate the positive directions of the X-axis, Y-axis, and Z-axis. The spray coating system 100 includes, for example, a spraying device 401, a winding device 402, a penetrating device 403, and a coloring device 404.

[0033] Spraying device 401 is configured to spray a target liquid onto target object 201. Target object 201 may include, for example, a flexible material such as a textile or packaging film. The target liquid may include, for example, a dye or a coating material. It should be understood that spraying device 401 sprays the target liquid onto the surface of target object 201, unlike conventional dyeing processes.

[0034] The winding device 402 is disposed downstream of the spraying device 401 and is configured to wind up the target object 201 after spraying.

[0035] The infiltration device 403 is configured to drive the rolled target object to rotate at a predetermined rotation speed for a first predetermined period, so as to allow the target liquid to infiltrate the target object 201 .

[0036] The coloring device 404 is configured to maintain the infiltrated target object 201 at the first predetermined temperature for a second predetermined period to develop color.

[0037] Figure 3 A schematic structural diagram of a winding device 402 according to an embodiment of the present disclosure is shown. Figure 4 A schematic diagram illustrating a partial structure of a winding device 402 according to an embodiment of the present disclosure is shown. The winding device 402 includes, for example, a support unit 302, a cantilever 304, a first active roller 306, and a first driven roller 308. The winding device 402 also includes a retractable support member 310, a first bending roller 312, and an A-frame 314.

[0038] The support unit 302 includes at least a first pivoting portion 322 and a second pivoting portion 324. One end of the cantilever 304 is pivotally connected to the first pivoting portion 322, allowing the cantilever 304 to rotate relative to the first pivoting portion 322 about the first pivoting portion 322. One end of the cantilever 304 is fixed relative to the first pivoting portion 322 and can be referred to as the "restricted end." The other end of the cantilever 304 (i.e., the end away from the first pivoting portion 322) can be referred to as the "free end." A first active roller 306 is disposed at the other end of the cantilever 304. The first active roller 306 is configured to drive the coated target object 201 toward the first active roller 308 via at least a pressure portion 361 of the first active roller 306 relative to the first driven roller 308. The first driven roller 308 is configured to rotate driven by the first active roller 306 so that the coated target object 201 is wound around the first driven roller 308 and reeled up.

[0039] It is worth noting that the pressure portion 361 of the first active roller 306 is the portion of the first active roller 306 that is capable of applying pressure to the first driven roller 308 (and the target object 201 between the first active roller 306 and the first driven roller 308). As the first active roller 306 rotates, the pressure portion 361 of the first active roller 306 dynamically changes. For example, the first driven roller 308 is positioned below the first active roller 306, and the pressure portion 361 of the first active roller 306 is, for example, the portion of the first active roller 306 located below. The first driven roller 308 is, for example, positioned on an A-shaped frame 314, which supports the first driven roller 308.

[0040] One end of the retractable support member 301 is pivotally connected to the second pivoting portion 324, and the other end of the retractable support member 310 is pivotally connected between one end and the other end of the cantilever 304. The retractable support member 310 is configured to extend as the outer diameter of the sprayed target object 201 wound around the first driven roller 308 increases. The retractable support member 310 includes a cylinder.

[0041] For example, in the initial state, due to the coordinated action of the cantilever 304 and the retractable support member 301, the pressure portion 361 of the first active roller 306 contacts the first driven roller 308 and applies pressure to the first driven roller 308. The sprayed target object 201 is transferred from the spraying device 401 to the winding device 402. The sprayed target object 201 is then transferred to the first active roller 306 via the first bending roller 312. It should be understood that the first bending roller 312 can maintain the sprayed target object 201 in a flat state and prevent wrinkles. The first active roller 306 is driven by a motor, for example, to rotate counterclockwise, causing the sprayed target object 201 to be transferred to the first driven roller 308 via the pressure portion 361. It is worth noting that since the first active roller 306 applies pressure to the first driven roller 308 through the pressure-applying portion 361, friction is generated when the first active roller 306 rotates, causing the first driven roller 308 to rotate in a clockwise direction, thereby driving the sprayed target object 201 to be wound around the surface of the first driven roller 308 and rolled up.

[0042] It should be understood that the coated target object 201 wound around the first driven roller 308 exerts pressure on the pressure portion 361 of the first active roller 306. As the outer diameter of the coated target object 201 wound around the first driven roller 308 increases, the first active roller 306 is lifted, and the cantilever 304 rotates counterclockwise relative to the first pivot portion 322, thereby extending the retractable support member 310. It should be noted that the retractable support member 310 may be a pneumatic cylinder. Therefore, the retractable support member 310 can provide appropriate support force, thereby ensuring that the first active roller 306 maintains an appropriate pressure against the first driven roller 308, thereby providing appropriate friction for the winding operation.

[0043] It is worth noting that the support unit 203 can also support multiple components in the spraying device 401.

[0044] After the winding is completed, the wound target object 201 can be moved to the infiltration device 403 by moving the A-frame 314. Alternatively, the wound target object 201 can be moved to the infiltration device 403 by other transport devices. The infiltration device 403, for example, includes a motor for driving the wound target object 201 to rotate. For example, the infiltration device 403 includes a storage space for accommodating the wound target object 201. For example, the wound target object 201 can be accommodated in a storage component and then moved to the storage space of the infiltration device 403, and the first driven roller 308 is coupled to the motor of the infiltration device 403. Then, the motor is started to drive the first driven roller 308 to rotate at a predetermined speed, thereby causing the wound target object 201 to rotate at the predetermined speed. The receiving member is, for example, a plastic bag. The rolled target object 201 is wrapped in the plastic bag and then moved into the receiving space of the infiltration device 403. The rolled target object 201 is rotated at a predetermined speed and for a first predetermined period at a second predetermined temperature so that the target liquid is uniformly infiltrated into the target object.

[0045] In some embodiments, the accommodation space of the infiltration device 403 is maintained at a second predetermined temperature, which is any value between 10 and 60 degrees Celsius. The first predetermined period during which the rolled target object 201 rotates at a predetermined speed is, for example, any value between 10 and 120 minutes. It should be understood that the target liquid is sprayed onto the surface of the target object 201, and the rolled target object 201 rotates at a predetermined speed, which facilitates uniform penetration of the target liquid into the target object 201. The first predetermined period is related to at least one of the following: the thickness of the target object, the material of the target object, the predetermined speed, the second predetermined temperature, and the penetration properties of the target liquid. For example, the thicker the target object, the longer the first predetermined period. The faster the penetration rate of the target liquid, the shorter the first predetermined period.

[0046] The coloring device 404 includes a coloring chamber configured to provide a first predetermined temperature and a predetermined humidity. The coloring device 404 is further configured to unroll the infiltrated target object 201 and cause the unrolled target object 201 to color in the coloring chamber.

[0047] Figure 5 A schematic diagram of a target object passing through a chromogenic device according to an embodiment of the present disclosure is shown. After the infiltration operation is completed, the infiltrated target object 201 can be unrolled and transferred to the chromogenic chamber of the chromogenic device 404. The infiltrated target object 201 can also be moved into the chromogenic chamber of the chromogenic device 404, then unrolled and transferred to the chromogenic chamber of the chromogenic device 404 for color development within the chromogenic chamber. The first predetermined temperature provided within the chromogenic chamber is any value between 80 and 160 degrees Celsius, the second predetermined period for color development within the chromogenic chamber is, for example, any value between 100 and 400 seconds, and the predetermined humidity provided within the chromogenic chamber is, for example, 100%. The chromogenic device 404 includes a steaming unit (e.g., a steamer).

[0048] The target object 201 after the color development operation may further undergo a step such as a water washing operation.

[0049] It is worth noting that using spraying device 401 for the spraying operation can significantly save time compared to the dyeing operation. Subsequently, the target liquid can be evenly penetrated into the target object 201 via the penetration device 403. Then, the target object 201 is dyed using a coloring device 404 (e.g., a vapor evaporation dyeing device), which can significantly reduce operation time and improve production efficiency.

[0050] Regarding the spraying device 401, Figure 6 A partial structural schematic diagram of a spraying device 401 according to an embodiment of the present disclosure is shown. Figure 7 Shown Figure 6 The spraying device 401 includes a spray head 412, a spray head driving device 414, a driving roller 102, and a first roller 104. The spraying device 401 also includes a second driven roller 110, a liquid collecting device 112, a scraper 114, and the like.

[0051] Regarding the driving roller 102 , it is used to transport the target object 201 out of the spraying area.

[0052] With respect to the first roller 104 , the target object 201 is transported to the spraying area via the first roller 104 , with at least a portion of the target object 201 extending between the drive roller 102 and the first roller 104 .

[0053] Regarding the spray head 412, it is disposed in the spraying area and is configured to continuously apply the target liquid in the form of a liquid column to at least the first surface of the target object 201 when the spraying device 401 is operating in the dyeing state. In some embodiments, the spraying device 401 further includes a liquid supply device for supplying the target liquid to the spray head 412. For example, the target liquid is supplied to the spray head 412 at a constant flow rate. For example, the liquid supply device is a constant flow liquid supply device for supplying the target liquid to the spray head 412 at a constant flow rate.

[0054] The nozzle driving device 414 can drive the nozzle 412 to move in the vertical direction and the horizontal direction.

[0055] The second driven roller 110 is configured to contact the driving roller 102 so that pressure is applied to the target object 201 passing between the second driven roller 110 and the driving roller 102, and under the action of the pressure, the target liquid applied to the target object 201 penetrates into the interior and / or the second surface of the target object 201.

[0056] To ensure that appropriate pressure is applied to the target object 201 passing between the second driven roller 110 and the driving roller 102, the spraying device 401 further includes a first lever 131 and a lever drive 132. For ease of understanding, the first lever 131 is illustrated as a blue line. One end of the first lever 131 is coupled to the second driven roller 110. The lever drive 132 is coupled to the other end of the first lever 131 and is configured to apply force to the other end of the first lever 131 to drive the first lever 131 to move relative to the first fulcrum 133, thereby driving the second driven roller 110 into contact with or away from the driving roller 102.

[0057] For example, when the lever driving device 132 applies a force in a first direction (e.g., the positive direction of the Y-axis) to the other end of the first lever 131, the first lever 131 can be driven to rotate counterclockwise relative to the first fulcrum 133, thereby causing the second driven roller 110 to contact the driving roller 102. It should be understood that the force applied by the second driven roller 110 to the driving roller 102 can be adjusted by adjusting the force applied by the lever driving device 132 to the other end of the first lever 131, so that an appropriate pressure is applied to the target object 201 passing between the second driven roller 110 and the driving roller 102.

[0058] When the lever driving device 132 applies a force in a second direction (for example, the negative direction of the Y axis) to the other end of the first lever 131 , the first lever 131 can be driven to rotate clockwise relative to the first fulcrum 133 , thereby separating the second driven roller 110 from the driving roller 102 .

[0059] In some embodiments, the lever driving device 132 includes, for example, a first cylinder configured to be extended or compressed to drive the first lever 131 to move relative to the first fulcrum 133 .

[0060] In some embodiments, the first cylinder is, for example, an airbag cylinder. The lever drive device 132 also includes a first tension spring assembly 134, which is configured to apply a force to the airbag cylinder along the direction in which the airbag cylinder is compressed. For example, when the airbag cylinder is inflated, the airbag cylinder is stretched along the positive direction of the Y-axis, thereby applying a force in a first direction (e.g., the positive direction of the Y-axis) to the other end of the first lever 131. At this time, the tension spring in the first tension spring assembly 134 is also stretched along the positive direction of the Y-axis. When the airbag cylinder is deflated, the airbag cylinder is compressed along the negative direction of the Y-axis, thereby applying a force in a second direction (e.g., the negative direction of the Y-axis) to the other end of the first lever 131. Simultaneously, the rebound force of the first tension spring assembly 134 can be utilized to facilitate the deflation of the airbag cylinder.

[0061] There are, for example, two first levers 131 , which are respectively coupled to the two ends of the roller shaft of the second driven roller 110 . There are, for example, two first cylinders, which are respectively provided corresponding to the two first levers 131 .

[0062] Regarding the scraper 114, it is disposed below the first roller 104 and is used to remove any residual target liquid from the surface of the first roller 104. It should be understood that the scraper 114 is in contact with the surface of the first roller 104. For example, the width of the scraper 114 matches the width of the first roller 104, e.g., the width of the scraper 114 is not less than the width of the first roller 104. In some operational scenarios, the width of the target object 201 is smaller than that of the first roller 104, while the width covered by the spray head 412 is slightly larger than that of the target object 201. Therefore, during the spraying operation, the target liquid is sprayed onto the surface of the first roller 104 in areas where the width covered by the spray head 412 exceeds the width of the target object 201, forming residual liquid. As the first roller 104 rotates driven by the drive roller 102, the scraper 114 removes any residual target liquid from the surface of the first roller 104, thereby preventing the residual liquid from seeping into the edges of the target object 201 and affecting the spraying quality.

[0063] In some embodiments, the spraying device 401 further includes a second lever 151 and a second tension spring assembly 152. One end of the second lever 151 is coupled to the scraper 114. The second tension spring assembly 152 is coupled to the other end of the second lever 151 and is configured to apply a force in a first direction (e.g., the positive direction of the Y axis) to the other end of the second lever 151, so that one end of the second lever 151 applies a force in a second direction (e.g., the negative direction of the Y axis) to the scraper 114, thereby causing the scraper 114 to contact (adhere to) the first roller 104. It should be understood that the first direction is opposite to the second direction.

[0064] Regarding the liquid collection device 112, it is disposed below the spraying area and is used to collect the target liquid. It is worth noting that during the spraying process, a small amount of the target liquid may fall from the outside of the target object 201, and the liquid collection device 112 can receive and collect the target liquid. Furthermore, the area covered by the liquid collection device 112 includes, for example, the area corresponding to the scraper 114. The target liquid removed from the surface of the first roller 104 by the scraper 114 can also flow into the liquid collection device 112.

[0065] Figure 8 Flowchart of a spray coating method 800 according to an embodiment of the present disclosure is shown. Spray coating method 800 can be implemented, for example, using spray coating system 100. It should be understood that method 2000 may include additional actions not shown and / or may omit actions shown, and the scope of the present disclosure is not limited in this respect.

[0066] At step 802 , a target liquid is sprayed onto a target object.

[0067] At step 804 , the sprayed target object is rolled up.

[0068] At step 806 , the rolled target object is driven to rotate at a predetermined speed for a first predetermined period, so as to allow the target liquid to penetrate into the target object.

[0069] At step 808 , the infiltrated target object is maintained at the first predetermined temperature for a second predetermined period to develop color.

[0070] For example, at step 802 , the target liquid is sprayed onto the target object 201 using the spraying device 401 .

[0071] At step 804 , the sprayed target object 201 is rolled up using the rolling device 402 .

[0072] For example, the coated target object 201 wound on the first driven roller 308 exerts pressure on the pressure portion 361 of the first active roller 306. As the outer diameter of the coated target object 201 wound on the first driven roller 308 increases, the first active roller 306 is lifted, and the cantilever 304 rotates counterclockwise relative to the first pivot portion 322, thereby extending the retractable support member 310. It should be noted that the retractable support member 310 may be a pneumatic cylinder. Therefore, the retractable support member 310 can provide appropriate support force, thereby ensuring that the first active roller 306 maintains an appropriate pressure against the first driven roller 308, thereby providing appropriate friction for the winding operation.

[0073] At step 806 , the rolled target object is driven to rotate at a predetermined speed for a first predetermined period by the penetration device 403 , so as to allow the target liquid to penetrate into the target object 201 .

[0074] At step 806, for example, the rolled target object 201 can be contained in a containing component (such as a plastic bag), and the rolled target object 201 can be rotated at a second predetermined temperature for a first predetermined period to ensure uniform penetration of the target liquid into the target object 201.

[0075] In some embodiments, the second predetermined temperature is any value between 10 and 60 degrees Celsius. The first predetermined period during which the rolled target object 201 rotates at the predetermined rotational speed is, for example, any value between 10 and 120 minutes. It should be understood that spraying the target liquid onto the surface of the target object 201 and rotating the rolled target object 201 at the predetermined rotational speed facilitates uniform penetration of the target liquid into the target object 201. The first predetermined period is related to at least one of the following: the thickness of the target object, the material of the target object, the predetermined rotational speed, the second predetermined temperature, and the penetration properties of the target liquid. For example, the thicker the target object, the longer the first predetermined period. The faster the penetration rate of the target liquid, the shorter the first predetermined period.
