Description

Technical Field

[0001] The invention relates to the technical field of fabric processing, and in particular to a printing device and a printing method for processing clothing fabrics. Background Art

[0002] The printing process in clothing fabric processing is a technology that forms patterns on the fabric surface through dyes, pigments or special chemical materials. It is widely used in the fields of fashion, home textiles and functional fabrics. It mainly includes digital printing, screen printing, thermal transfer, reactive printing and other processes. It can not only improve the beauty and personalized design of clothing, but also give the fabric specific functions, such as waterproof and UV protection. Choosing the appropriate printing method according to different needs can achieve efficient production, bright colors, comfortable feel and other characteristics, and meet the market's growing demand for personalized and environmentally friendly printing and dyeing.

[0003] In the unwinding process of traditional printing machines, the shaft diameter of the unwinding rack is usually fixed, while the inner diameter specifications of the cloth roll and paper roll are quite different, resulting in a gap after installation, causing the cloth roll or paper roll to shake during the unwinding process, and the unwinding is unstable. In addition, since the shaft cannot fit tightly, eccentricity may occur during rotation, that is, the substrate rotates around the non-central axis, causing the unwinding tension to be strong or weak, which in turn causes local wrinkles or relaxation of the substrate. At the same time, eccentric rotation may also cause the material axis to shift, causing the cloth roll or paper roll to swing radially when running at high speed, resulting in irregular unwinding trajectory, affecting the conveying accuracy, and then affecting the registration accuracy of the transfer pattern. During high-speed printing, the eccentric state may cause resonance or abnormal noise, and even have an adverse effect on the overall operation of the equipment. Summary of the invention

[0004] The purpose of the present invention is to solve the problem of insufficient stability of a fixed diameter unwinding rack in the prior art when adapting to cloth rolls and paper rolls with different inner diameters, resulting in uneven unwinding, difficulty in tension control, wrinkles on the substrate and reduced transfer accuracy, and to propose a printing device and a printing method for clothing fabric processing.

[0019] Step 4: Correct the deviation and remove the wrinkles to ensure the substrate is flat.

[0020] Compared with the prior art, the present invention provides a printing device and a printing method for processing clothing fabrics, which have the following beneficial effects:

[0021] The printing device for processing clothing fabrics performs the unwinding operation of the substrate through an unwinding assembly fixed on a supporting frame, wherein a placing drum is used to support the rotation of the roll, and a plurality of positioning plates installed inside the placing drum are controlled by a driving member to slide and insert into the positioning groove of the roll, so that the roll is kept centrally positioned, thereby avoiding wrinkles or relaxation caused by uneven tension of the substrate due to eccentricity or shaking of the roll during the unwinding process.

The unwinding substrate is transported to the hot pressing printing area through the guide assembly. The hot pressing roller and the auxiliary roller form a pressing gap. The hot pressing roller provides high temperature heating to make the printing ink penetrate into the surface of the substrate. The auxiliary roller adjusts the pressure to ensure uniform printing without wrinkles. The system optimizes the unwinding and hot pressing process to ensure printing quality and production efficiency, and solves the problems of substrate eccentricity, wrinkles and uneven printing.

[0051] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0052] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] Example:

[0054] Reference Figure 1-Figure 15 A printing device for processing clothing fabrics includes a support frame 1, and also includes: an unwinding component 2 fixedly installed on the support frame 1, which performs a coil unwinding action when working, wherein the unwinding component 2 includes a placing cylinder 205, and the placing cylinder 205 is provided with a reel 10 for winding a substrate on the outside, and a plurality of positioning plates 206 are slidably installed inside the placing cylinder 205. A driving member arranged inside the placing cylinder 205 drives the positioning plate 206 to plug into the positioning groove of the reel 10 to perform a center positioning operation on the reel 10; a hot pressing roller 5 installed on the support frame 1 is rotated to perform a hot pressing transfer action; an auxiliary roller 6 installed on the support frame 1 is rotated, and a pressing gap is formed between the auxiliary roller 6 and the hot pressing roller 5. When the printing material passes through, the hot pressing roller 5 and the auxiliary roller 6 perform a rotating hot pressing printing action.

[0055] The above-mentioned printing device for processing clothing fabrics performs the unwinding operation of the substrate through the unwinding component 2 fixed on the support frame 1, wherein the placing cylinder 205 is used to support the rotation of the roll 10, and the multiple positioning plates 206 installed inside the placing cylinder 205 are controlled by the driving member to slide and insert into the positioning groove of the roll 10, so that the roll 10 maintains the center positioning, thereby avoiding the uneven tension of the substrate caused by the eccentricity or shaking of the roll 10 during the unwinding process, resulting in wrinkles or relaxation. The unwound substrate is adjusted by the guide component to adjust the conveying path and enter the hot pressing printing area. In this process, the hot pressing printing part is composed of a hot pressing roller 5 with an outer layer coated with a high temperature resistant material and an auxiliary roller 6 with adjustable surface elasticity, and the two form a pressing space The printing material and the substrate enter the laminating gap at the same time, and the hot pressing roller 5 softens the ink layer on the printing material by the stable high temperature, and penetrates and transfers to the surface of the substrate under the pressure. At the same time, the auxiliary roller 6 adjusts the laminating force by its own elasticity to adapt to substrates of different thicknesses and prevent the degradation of printing quality due to uneven pressure. After the substrate and the printing material pass through the laminating area, the printing is completed and a stable pattern is formed. By optimizing the fixing method of the reel 10, adjusting the conveying path of the substrate, and accurately controlling the temperature and pressure during the hot pressing process, the integrity, clarity and adhesion of the printed pattern are ensured, and the stability and production efficiency of fabric processing are improved.

[0056] Preferably, two unwinding assemblies 2 are provided, one of which is fixed at the lower part of one side of the support frame 1, and a reel 10 for winding up the cloth roll 11 is installed externally thereon, and the other unwinding assembly 2 is fixed at the upper part of one side of the support frame 1, and a reel 10 for winding up the paper roll 12 is installed externally thereon. In order to realize the telescopic control of the positioning plate 206, further, a bidirectional screw rod 207 is rotatably installed inside the placement cylinder 205, a slider 208 is screwed externally thereon, a guide groove 210 is provided inside the positioning plate 206, a guide seat 209 fixed externally thereon the slider 208 is inserted into the positioning plate 206 and is slidably connected to the guide groove 210, the bidirectional screw rod 207 rotates, controls the movement of the two sliders 208, and then the positioning plate 206 performs telescopic action.

[0057] Two unwinding components 2 are arranged on the support frame 1, one is used to wind up the cloth roll 11, and the other is used to wind up the paper roll 12, which are respectively fixed on the upper and lower parts of the support frame 1, and the reel 10 is installed externally by plugging and mounting, and a bidirectional screw rod 207 is installed inside the placement tube 205 as a driving member, and the bidirectional screw rod 207 is externally screwed with a slider 208, and the slider 208 is connected to a guide seat 209 fixed on the positioning plate 206, and the guide seat 209 is plugged into the positioning plate 206 and is slidably connected with its internal guide groove 210. The rotation of the bidirectional screw rod 207 drives the slider 208 to move axially, and controls the extension and retraction of the positioning plate 206, thereby realizing accurate center positioning and tension adjustment of the reel 10, ensuring that the cloth roll 11 and the paper roll 12 are stably and evenly unwound in substrates of different sizes during the unwinding process, and at the same time avoiding wrinkles or relaxation of the substrate caused by eccentricity or uneven tension of the reel 10, ensuring that the printing material enters the subsequent hot pressing transfer process smoothly and stably.

[0058] In order to realize the rotational installation of the placement cylinder 205, further, the first support seat 201 and the second support seat 202 fixed on the support frame 1 are supported to rotate and install the placement cylinder 205, and the first support seat 201 and the second support seat 202 are distributed on both sides of the support frame 1. In order to realize the flipping of the placement cylinder 205 based on the second support frame 1, further, one side of the rotating rod 203 rotatably installed on the second support seat 202 is rotatably installed with a sleeve rod 204, and the sleeve rod 204 is plugged with one end of the placement cylinder 205. In order to facilitate the disassembly and assembly of the reel 10 and control the rotation of the bidirectional screw rod 207, further, one side of the screw tube 213 screwed on the first support seat 201 is movably plugged into the end of the placement tube 205 away from the second support seat 202. When the screw tube 213 rotates, the main body of the screw tube 213 approaches the second support seat 202 and plugs into the placement tube 205. A driving rod 214 is installed inside the screw tube 213 for rotation. The plug plate 211 fixed at one end of the driving rod 214 passes through the screw tube 213 and is plugged into the slot 212 at one end of the bidirectional screw rod 207. When the driving rod 214 rotates, the rotation of the bidirectional screw rod 207 is controlled.

[0059] The first support seat 201 and the second support seat 202 are respectively fixed on both sides of the support frame 1 to realize the rotation installation of the placement cylinder 205. The placement cylinder 205 can rotate freely between the two support seats to ensure that the roll 10 can be unwound smoothly and stably under different working conditions, avoiding uneven tension and wrinkles of the substrate caused by fixing problems. In order to facilitate the disassembly and maintenance of the roll 10, one end of the placement cylinder 205 is connected to the rotating rod 203 on the second support seat 202 through the sleeve rod 204. This design allows the placement cylinder 205 to be turned over, which is convenient for the operator to replace or adjust the roll 10, ensuring that the unwinding needs of different rolls can be quickly handled during the production process.

[0060] At the same time, the screw tube 213 is movably plugged with the other end of the placement tube 205. When the screw tube 213 rotates, the main body of the screw tube 213 approaches the second support seat 202, thereby plugging the placement tube 205, providing stable support, and can be easily disassembled as needed. The driving rod 214 inside the screw tube 213 is connected to the bidirectional screw rod 207. By rotating the driving rod 214 to control the rotation of the bidirectional screw rod 207, the bidirectional screw rod 207 can accurately adjust the telescopic position of the positioning plate 206, further ensuring the stability of the reel 10 during the unwinding process.

[0061] Through the precise control of the screw tube 213 driving the rod 214, the device can be adjusted according to different production needs, the rotation position of the bidirectional screw rod 207 can be adjusted, and the telescopic action of the positioning plate 206 inside the placement tube 205 can be realized, so that the unwinding component 2 can adapt to the size changes of different rolls 10, ensuring that even when the inner diameter and the outer diameter of the roll 10 are inconsistent, the unwinding stability of the substrate can still be guaranteed, avoiding the wrinkles, relaxation or uneven tension distribution of the substrate caused by the eccentricity of the roll 10, thereby ensuring the accuracy of the subsequent hot pressing transfer process and the stability of the printing quality. In addition, the cooperation between the screw tube 213 and the driving rod 214 realizes efficient transmission and ease of operation, reduces the need for manual intervention, improves production efficiency, and ensures the long-term stable operation of the device. Through the optimization of this structure, flexible adaptation of the cloth roll 11 and the paper roll 12 can be achieved, effectively improving the work efficiency and finished product quality in the clothing fabric processing process.

[0062] In order to realize the guided transmission of the paper roll 12 of the cloth roll 11, the printing device further includes an electric guide roller 3, and two electric guide rollers 3 are provided. The substrate of the cloth roll 11 passes through the lower part of the electric guide roller 3 located at the lower part and then passes through the pressing gap, and the substrate of the paper roll 12 passes through the upper part of the electric guide roller 3 located at the upper part and then passes through the pressing gap. In order to realize the fine adjustment of the hot pressing gap according to the thickness of the paper roll 12 of the cloth roll 11, the auxiliary roller 6 further includes an electric roller body 601, an air inlet seat 603 fixed on the support frame 1 and the electric roller body 601 is rotatably installed inside the air pipe 9, and a tubular airbag 602 is fixedly installed outside the electric roller body 601, and an expansion gap 604 is opened inside the tubular airbag 602. When the air inlet seat 603 is connected to an external air source, the expansion degree of the tubular airbag 602 is controlled to adjust the pressing gap.

[0063] In order to achieve stable guided transmission of the cloth roll 11 and the paper roll 12, an electric guide roller 3 is used. Two electric guide rollers 3 are provided, which are respectively located at the upper and lower parts of the support frame 1. The base material of the cloth roll 11 passes under the lower electric guide roller 3 and then enters the pressing gap between the hot pressing roller 5 and the auxiliary roller 6; the base material of the paper roll 12 passes through the upper electric guide roller 3 and then passes through the same pressing gap.

[0064] The two electric guide rollers 3 ensure that the substrate can be smoothly transported and maintain a stable position before entering the lamination area, avoiding deviation or wrinkles of the substrate. In addition, in order to adapt to the different thicknesses of the cloth roll 11 and the paper roll 12, an electric roller body 601 with an adjustable lamination function is designed in the auxiliary roller 6. The electric roller body 601 is installed on the support frame 1 through rotation in the air inlet seat 603 and the air pipe 9, and the external tubular airbag 602 is fixed on the outside of the electric roller body 601.

[0065] The tubular airbag 602 has an expansion gap 604 inside. When the air source is connected and started through the air inlet seat 603, the tubular airbag 602 will expand, thereby adjusting the pressure of the lamination roller and fine-tuning the size of the hot lamination gap to adapt to substrates of different thicknesses, ensuring uniform and stable lamination force, and avoiding uneven contact between the printing material and the substrate due to improper lamination, which affects the transfer quality.

[0066] This adjustment mechanism ensures that when the cloth roll 11 and the paper roll 12 are of different thicknesses, the clarity and stability of the printing can be guaranteed through precise pressing control, avoiding pattern misalignment or unclearness caused by thickness differences during the printing process, optimizing the transfer effect, and through automatic adjustment, reducing manual intervention, thereby improving work efficiency and production stability.

[0067] In order to remove wrinkles from the cloth roll 11 and the paper roll 12, further, two correcting rollers 4 for de-wrinkling the substrate are rotatably installed on the upper part of the support clamp, and a correcting gap through which the substrate can pass is formed between the two correcting rollers 4, one end of the two correcting rollers 4 passes through the support frame 1 and is fixedly connected with gears 403 respectively, the two gears 403 are meshed and connected, a first rotating wheel 404 fixed on one side of one of the gears 403 and a second rotating wheel 405 fixed on one end of one of the electric guide rollers 3 are driven by a variable speed belt, when the electric guide roller 3 is working, the two correcting rollers 4 are driven to perform a variable speed rotation and de-wrinkling action, wherein the correcting roller 4 includes a rotating shaft 401 rotatably installed on the support frame 1, symmetrically arranged spiral airbags 402 are fixedly installed on the outside of both sides of the rotating shaft 401, the spiral airbags 402 are connected with the rotating shaft 401, the two rotating shafts 401 are connected with the air plate 7 fixed on one side of the support frame 1, the air plate 7 is connected with the air pipe 9 through the transmission pipe 8, and when the external air source is working, the size of the correcting gap is changed synchronously.

[0068] In order to remove wrinkles from the cloth roll 11 and the paper roll 12, two correcting rollers 4 for removing wrinkles from the substrate are designed. The two correcting rollers 4 are installed on the upper part of the support frame 1 and can rotate. A set correcting gap between the two correcting rollers 4 allows the substrate to pass smoothly.

[0069] During the wrinkle removal operation, the two ends of the deflection correction roller 4 are respectively fixedly connected with gears 403 through the support frame 1, and the two gears 403 are meshed and connected and driven to rotate with each other. The first rotating wheel 404 fixed on one side of one of the gears 403 and the second rotating wheel 405 fixedly connected to one end of the electric guide roller 3 are driven by a variable speed belt. When the electric guide roller 3 is working, it drives the rotation of the gear 403 group, thereby driving the two deflection correction rollers 4 to rotate at a variable speed, thereby realizing the wrinkle removal operation of the substrate.

[0070] In order to further enhance the wrinkle removal effect, a symmetrically arranged spiral airbag 402 is designed on the outside of the deviation correction roller 4. The spiral airbag 402 is connected to the rotating shaft 401. When the rotating shaft 401 rotates, the spiral airbag 402 pulls the two sides of the substrate through its own spiral structure, thereby achieving the purpose of wrinkle removal.

[0071] When the air source is started, the air plate 7 synchronously adjusts the expansion degree of the spiral airbag 402 and the size of the correction gap. The air source can adjust the correction gap according to the thickness of the substrate and the degree of wrinkles, thereby achieving a more accurate and effective wrinkle removal operation.

[0072] In another embodiment:

[0073] In order to achieve the cleaning and cooling of the material, further, the output end of the pneumatic part 13 fixed on one side of the support frame 1 is fixedly connected to one end of the deviation correction roller 4, the electric guide roller 3 is provided with a spiral gap 302 and a longitudinal gap 301, and the electric guide roller 3 is provided with an air passage, and the air passage penetrates the longitudinal gap 301 and the spiral gap 302 at one time. The input end of the pneumatic part 13 is connected and penetrated with the guide plate 14 fixed on one side of the support frame 1 through the first guide pipe 17, and the guide plate 14 is rotatably connected and penetrated with the two electric guide rollers 3, and one side of the support frame 1 is fixedly installed A cooling roller 15 is provided, and the cooling roller 15 is provided with a longitudinal flow channel 19 and a transverse flow channel 20. The cooling roller 15 is hollow, and the longitudinal flow channel passes through the transverse flow channel 20 and the inner cavity of the cooling roller 15 respectively. One end of a filter cartridge 16 fixed on one side of the support frame 1 is rotatably connected to the cooling roller 15, and the other end of the filter cartridge 16 is connected to the output end of the pneumatic component 13 through a second guide tube 18. When the substrate is transmitted, the pneumatic component 13 absorbs the dust on the rotating substrate through the two electric guide rollers 3, and cools the material after the hot pressing transfer through the cooling roller 15.

[0074] In order to realize the dust adsorption pretreatment of the material, the printing device installs a pneumatic part 13 on one side of the support frame 1, and the output end of the pneumatic part 13 is fixedly connected to one end of the deviation correction roller 4, and is connected and connected with the guide plate 14 on the support frame 1 through the first guide tube 17. The guide plate 14 is rotatably connected with the two electric guide rollers 3, and the electric guide rollers 3 are provided with a spiral gap 302, a longitudinal gap 301 and an air duct running through them. When the deviation correction roller 4 rotates, the pneumatic part 13 is driven to work, and a negative pressure is formed in the air duct, so that the air flows along the spiral gap 302 and the longitudinal gap 301, thereby adsorbing surface dust and impurities during the transmission of the substrate, so that the substrate can be kept clean before entering the hot pressing printing, and dust is prevented from affecting the printing quality;

[0075] In addition, the filter cylinder 16 is connected to the cooling roller 15, and is connected to the output end of the pneumatic part 13 through the second guide tube 18, so that the adsorbed dust is collected after passing through the filter cylinder 16 to prevent environmental pollution. In order to cool the material after the hot pressing transfer is completed, a cooling roller 15 is installed on one side of the support frame 1. The cooling roller 15 adopts a hollow structure, and a longitudinal flow channel 19 and a transverse flow channel 20 are designed inside, so that the cooling medium can circulate in its inner cavity. The cooling roller 15 rotates so that the substrate can fully contact it when passing through it, thereby achieving uniform cooling. At the same time, the cooling roller 15 is connected to the filter cylinder 16. While the pneumatic part 13 adsorbs dust on the substrate, it can also control the airflow to enter the inner cavity of the cooling roller 15 through the filter cylinder 16, so that the airflow is distributed along the longitudinal flow channel 19 and the transverse flow channel 20, thereby further improving the cooling efficiency. This cooling method can effectively reduce the temperature of the substrate, avoid material deformation caused by high temperature, and improve the printing quality and stability of the substrate.

[0076] The pneumatic part 13 is rotated by a pneumatic housing 1301, a pneumatic disk 1302, a pneumatic connecting rod 1303 and a piston plate 1304. A starting disk fixedly connected to the deviation correction roller 4 is rotatably installed inside the pneumatic housing 1301 fixed on one side of the support frame 1. The pneumatic connecting rod 1303 rotatably installed on the pneumatic disk 1302 is rotatably connected to the piston plate 1304 slidably installed in the pneumatic housing 1301. When the deviation correction roller 4 rotates, the piston plate 1304 performs a reciprocating motion, cooperating with the two one-way valves on the upper part of the pneumatic housing 1301 to perform an air extraction and blowing action.

[0077] A printing method for processing clothing fabrics also includes the following steps:

[0078] Step 1: Unwind and position to prevent eccentricity;

[0079] Step 2: Double unwinding structure, adapted to the cloth paper roll 12;

[0080] Step 3: Precise pressing and dynamic gap adjustment;

[0081] Step 4: Correct the deviation and remove the wrinkles to ensure the substrate is flat.

[0082] In the present invention, the unwinding operation of the substrate is performed by the unwinding assembly 2 fixed on the support frame 1, wherein the placing cylinder 205 is used to support the rotation of the roll 10, and the multiple positioning plates 206 installed inside the placing cylinder 205 are controlled by the driving member to slide and insert into the positioning groove of the roll 10, so that the roll 10 is kept in the center position, thereby avoiding the uneven tension of the substrate caused by the eccentricity or shaking of the roll 10 during the unwinding process, resulting in wrinkles or relaxation. The unwound substrate is conveyed by the guide assembly to adjust the conveying path and enter the hot embossing area. In this process, the hot embossing part is controlled by the outside The hot pressing roller 5 is coated with a layer of high-temperature resistant material and the auxiliary roller 6 with adjustable surface elasticity. The two form a pressing gap and rotate synchronously. When the printing material and the substrate enter the pressing gap at the same time, the hot pressing roller 5 softens the ink layer on the printing material through the stable high temperature, and penetrates and transfers to the surface of the substrate under pressure. At the same time, the auxiliary roller 6 adjusts the pressing force by its own elasticity to adapt to substrates of different thicknesses and prevent the printing quality from decreasing due to uneven pressure. After the substrate and the printing material pass through the pressing area, the printing is completed and a stable pattern is formed.

[0083] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
