Description

Technical Field

[0001] This application relates to the field of textile processing technology, and in particular to a high-definition fabric printing equipment and printing process. Background Technology

[0002] The process of applying dyes or pigments to create patterns on fabric is called fabric printing. Printing involves partial dyeing and requires a certain degree of colorfastness. It is one of the important methods of decorating fabric patterns.

[0003] In existing technologies, printing is required to be dried after printing to ensure the clarity of the print. However, current partial drying methods, due to the high temperature, cause the print to crack, reducing the clarity of the fabric print. Summary of the Invention

[0004] To improve the clarity of fabric printing, this application provides a high-definition fabric printing device and printing process.

[0005] Firstly, The high-definition fabric printing equipment provided in this application adopts the following technical solution: A high-definition fabric printing device includes a printing section, which has an inlet and an outlet. A drying section is provided at the outlet. The drying section includes a first drying section and a second drying section. The second drying section is attached to the side wall of the first drying section, and a moving part for driving the fabric is provided inside the second drying section. The moving part can move within the first drying section and the second drying section, and a moving groove is provided on the side wall of the first drying section and the second drying section to facilitate the movement of the moving part. A support frame is fixed on the ground, and a moving rod is fixed on the support frame. The moving rod is vertically arranged and a moving block is slidably arranged on the moving rod. A first sliding rod is fixed on the moving part and is slidably arranged inside the moving block. The moving rod is also provided with a control component to facilitate the movement of the moving part in the first drying part and the second drying part. The control component includes operating parts fixed to both ends of the moving rod. The operating parts are provided with operating slots, and the inner sidewalls of the operating slots are provided with operating guide surfaces, with the operating guide surfaces in the two operating slots located on different sidewalls. The moving block is provided with a moving slot, and a second sliding rod is slidably disposed in the moving block. The second sliding rod passes through the moving slot and is used to control the sliding of the moving parts. The second sliding rod contacts the operating guide surface to adjust the position of the moving parts.

[0006] By adopting the above technical solution, the temperatures of the first drying section and the second drying section are different, with the temperature of the first drying section being lower than that of the second drying section. Under the driving action of the moving part, the fabric moves from the first drying section to the second drying section, allowing the printed fabric to undergo drying from low temperature to high temperature, reducing the possibility of unclear fabric printing due to high initial drying temperature. The control component controls the movement of the moving part within the first and second drying sections. The moving block can move along the length of the moving rod, i.e., vertically. By driving the first sliding rod to move within the moving block, the movement of the moving part can be controlled, making the control method relatively convenient. Operating parts are provided at both ends of the moving rod, and operating grooves are opened on the operating parts. During the movement, the second sliding rod contacts the operating guide surface on the side wall of the operating groove. Under the action of the operating guide surface, the position of the second sliding rod is adjusted. At the same time, the second sliding rod controls the sliding of the moving part, achieving the effect of adjusting the position of the moving part, i.e., adjusting the position of the moving part at the top and bottom of the moving rod.

[0007] Optionally, the first sliding rod extends to the outside of the moving block and a steering gear is fixed to the end of the first sliding rod. A steering rack is fixed on the moving rod. The steering gear meshes with the steering rack during the movement from the bottom of the moving rod to the top of the moving rod, and the length of the steering rack is half the circumference of the steering gear.

[0008] By adopting the above technical solution, during the process of the moving block driving the moving part to move from the bottom of the moving rod to the top of the moving rod, the steering gear contacts the steering rack. Under the action of the steering rack, the steering gear rotates and drives the first sliding rod to rotate, thereby driving the moving part to flip. When the moving part moves in the second drying part, the end face of the fabric on the moving part in the direction of the main moving part is convenient for the drying process.

[0009] Optionally, electrostatic suction cups for adsorbing fabric are fixed to both ends of the moving part.

[0010] By adopting the above technical solution, the electrostatic suction cup can adsorb fabric and dust on the fabric, thus having a cleaning effect.

[0011] Optionally, two feeding rings are rotatably arranged at the feed inlet, the two feeding rings are coaxially arranged, an electrostatic chuck is fixed on the side wall of the feeding ring, and the electrostatic chucks on the two feeding rings are in the same position. A pushing block for pushing the fabric away from the electrostatic chuck is provided at the feed inlet.

[0012] By adopting the above technical solution, an electrostatic chuck is provided on the side wall of the feeding ring. During the rotation of the feeding ring, the electrostatic chuck moves with the feeding ring and adsorbs the fabric. When the fabric moves to the feeding port, it separates from the feeding ring under the action of the pushing block, which facilitates the transfer of the fabric to the printing section.

[0013] Optionally, a push rod is fixed to the side wall of the printing section, the push block is slidably disposed on the push rod, the push rod is placed between the two feeding rings, a first push rod is rotatably connected to the push block, a second push rod is rotatably connected to the end of the first push rod, and the rotating shaft at the end of the second push rod is coaxially disposed with the feeding ring.

[0014] By adopting the above technical solution, the rotating shaft at the end of the second push rod is coaxially set with the feeding ring. That is, as the feeding ring rotates, the second push rod rotates synchronously. The rotation of the second push rod drives the first push rod to rotate, and the first push rod drives the pushing block to slide on the pushing rod, thereby pushing the fabric toward the printing part.

[0015] Optionally, the printing section is provided with a conveyor belt, and the conveyor belt is fixed with a number of electrostatic suction cups for holding the fabric.

[0016] By adopting the above technical solution, a conveyor belt is set inside the printing section, and several electrostatic suction cups for holding the fabric are fixed on the conveyor belt. The electrostatic suction cups on the conveyor belt attract the fabric and move under the action of the conveyor belt, so that the fabric can be transferred to the outside of the printing section after the printing is completed.

[0017] Optionally, the first drying section has a first inlet on its side wall to facilitate the entry of fabric, and the second drying section has a first outlet at its bottom to facilitate the unloading of fabric.

[0018] By adopting the above technical solution, the first drying section has a first inlet on its side wall to facilitate the entry of fabric, and the second drying section has a first outlet at its bottom to facilitate the unloading of fabric. The first inlet facilitates the entry of fabric into the first drying section. At this time, the electrostatic suction cups on the conveyor belt no longer perform adsorption, and the electrostatic suction cups on the moving part are activated to adsorb the fabric. The first outlet facilitates the transfer of fabric to the outside of the first drying section. When the moving part moves to the first outlet, it stops adsorption, which facilitates the fabric transfer process.

[0019] Secondly, This application also discloses a printing process applicable to the above-mentioned high-definition fabric printing equipment, comprising the following steps: a. Transport the fabric to the bottom of the feeding ring, and the feeding ring rotates to feed the fabric; b. The fabric is blocked by the push rod during rotation and transferred to the conveyor belt under the action of the first push rod and the second push rod. c. The fabric is printed within the printed section; d. The fabric enters the first drying section under the action of the conveyor belt and is held by the moving part; e. The moving part drives the fabric to dry in the first and second drying sections; f. Feeding.

[0020] By adopting the above technical solution, after the fabric printing is completed, it is dried in the first drying section and the second drying section, and the temperature increases in a stepwise manner, which reduces the possibility of print cracking caused by excessive temperature, thereby improving the clarity of the print.

[0021] In summary, this application includes at least one of the following beneficial technical effects of high-definition fabric printing equipment and printing process: 1. The first drying section and the second drying section have different temperatures. The temperature of the first drying section is lower than that of the second drying section. Driven by the moving part, the fabric moves from the first drying section to the second drying section, so that the printed fabric undergoes drying from low temperature to high temperature, reducing the possibility of unclear fabric printing due to high initial drying temperature. 2. The printing section is equipped with a conveyor belt, and several electrostatic suction cups for holding the fabric are fixed on the conveyor belt. The electrostatic suction cups on the conveyor belt attract the fabric and move under the action of the conveyor belt, so that the fabric can be transferred to the outside of the printing section after the printing is completed.

[0028] The following is in conjunction with the appendix Figure 1-5This application will be described in further detail.

[0029] Firstly, This application discloses a high-definition fabric printing device. (Refer to...) Figure 1 and Figure 2 The high-definition fabric printing equipment includes a printing section 1, which is used for printing fabrics. This printing section 1 is suitable for printing small pieces of fabric. The printing section 1 has an inlet and an outlet. The inlet facilitates the transfer of fabric into the printing section 1, and the outlet facilitates the transfer of fabric from inside the printing section 1 to the outside. A drying section 2 is located at the outlet, used to dry the printed fabric. The drying section 2 includes a first drying section 3 and a second drying section 4. Resistance wires are installed on the inner walls of both the first drying section 3 and the second drying section 4. The temperatures inside the first drying section 3 and the second drying section 4 are different; the section closer to the outlet is the first drying section 3, and the section further away is the second drying section 4. The temperature inside the first drying section 3 is lower than the temperature inside the second drying section 4. The fabric undergoes initial drying in the first drying section 3 and then moves to the second drying section 4 for secondary drying. This reduces the possibility of print cracking due to excessively high drying temperatures, improves print clarity, and enhances print quality.

[0030] Reference Figure 1 and Figure 2 The first drying section 3 and the second drying section 4 are fitted together on their side walls. A moving part 5 is installed inside the second drying section 4. The moving part 5 is used to move the fabric within the first drying section 3 and the second drying section 4. A moving groove 6 is provided on the side wall where the first drying section 3 and the second drying section 4 contact each other, facilitating the movement of the moving part 5. Both the first drying section 3 and the second drying section 4 are vertically arranged. The moving part 5 is plate-shaped, and a first sliding rod 10 is integrally formed and fixed to the side wall of the moving part 5. The first sliding rod 10 passes through the moving groove 6. Openings are provided at the top and bottom of the side wall where the first drying section 3 and the second drying section 4 contact each other. Initially, the moving part 5 is placed in the first drying section... Inside the first drying section 3, the fabric moves from the bottom to the top of the first drying section 3. After reaching the top of the first drying section 3, the moving part 5 transfers to the second drying section 4 and moves from the top to the bottom of the second drying section 4, allowing the fabric to pass through the first drying section 3 and the second drying section 4 in sequence, thus improving the uniformity of fabric drying. The first drying section 3 has a first inlet 28 on its side wall, which facilitates the transfer of fabric from the printing section 1 to the first drying section 3. The second drying section 4 has a first outlet 27 at its bottom, which facilitates the fabric feeding process. During this process, the fabric always faces the direction of movement of the moving part 5, which facilitates the drying process.

[0031] Reference Figure 2 , Figure 3 and Figure 4A support frame 7 is fixed to the ground by bolts. The first drying section 3 and the second drying section 4 are both fixed to the support frame 7 by bolts. A moving rod 8 is fixed to the support frame 7 by bolts. The moving rod 8 is vertically arranged and a moving block 9 is slidably arranged on the moving rod 8. That is, the moving block 9 can slide along the length of the moving rod 8. A moving electric cylinder is fixed to the top of the moving rod 8 by bolts. The piston rod of the moving electric cylinder is connected to the moving block 9 by bolts. When the moving electric cylinder is activated, it drives the moving block 9 to slide.The moving part 5 is provided with a sliding groove, and the first sliding rod 10 passes through the sliding groove and can slide along the axis of the sliding groove. The moving rod 8 is also provided with a control component to facilitate the movement of the moving part 5 in the first drying part 3 and the second drying part 4. The control component includes two operating parts 11, which are respectively fixed at both ends of the moving rod 8 along its length. The height of the operating parts 11 is less than the opening height of the two ends of the sidewalls of the first drying part 3 and the second drying part 4 that are in contact. The operating parts 11 are L-shaped and have operating grooves 12. The openings of the operating grooves 12 on the two operating parts 11 are arranged opposite each other, and the inner sidewall of the operating grooves 12 has an operating guide surface 13. The operation guide surface 13 is formed on different inner sidewalls of the operation slot 12. The moving block 9 is provided with a moving slot 25. The length direction of the moving slot 25 is the same as the length direction of the first sliding rod 10. A second sliding rod 14 is slidably arranged inside the moving block 9. The second sliding rod 14 is T-shaped, and the side rod in the middle of the second sliding rod 14 passes through the moving slot 25 and extends to the outside of the moving slot 25. The second sliding rod 14 is used to control the sliding of the moving part 5. The second sliding rod 14 contacts the operation guide surface 13 to adjust the position of the moving part 5. The first drying part 3 extends to the outside of the moving block 9, and the end of the first sliding rod 10 is fixed with a steering gear 15 by bolts. The steering gear 15 and the first... A sliding rod 10 is coaxially arranged, and a steering rack 16 is fixed to the moving rod 8 by bolts. As the steering gear 15 moves from the bottom of the moving rod 8 toward the bottom of the moving rod 8, it meshes with and rotates with the steering rack 16. The length of the steering rack 16 is half the circumference of the steering gear 15, meaning that the steering gear 15 rotates 180° upon contact with the steering rack 16, causing the moving part 5 to flip horizontally. A drive block 29 is integrally formed at the end of the second sliding rod 14. The drive block 29 is C-shaped with its opening facing downwards in the vertical direction. The steering gear 15 is placed inside the opening of the drive block 29, meaning that the movement of the drive block 29 can drive the steering gear 15, thereby driving... The first sliding rod 10 moves, thereby driving the moving part 5 to move. When the moving block 9 moves to the operating groove 12 at the top of the moving rod 8, the second sliding rod 14 contacts the operating guide surface 13 of the operating groove 12. Under the action of the operating guide surface 13, the second sliding rod 14 is pushed, thereby driving the moving part 5 to move, so that the moving part 5 is transferred into the second drying part 4. The moving block 9 moves downward, and when it moves to the operating groove 12 at the bottom of the moving part, under the action of the operating guide surface 13, the moving part 5 resets and moves back into the first drying part 3. At the same time, electrostatic suction cups 17 are fixed on both ends of the moving part 5. The electrostatic suction cups 17 are used to adsorb the fabric, which facilitates the drying process.

[0032] Reference Figure 1 and Figure 5A feeding rack is bolted to the ground at the feed inlet. Two feeding rings 18 are rotatably mounted on the feeding rack via a rotating shaft, meaning two feeding rings 18 are rotatably mounted at the feed inlet. The two feeding rings 18 are coaxially arranged, and electrostatic suction cups 17 are bolted to the outer walls of the feeding rings 18. The electrostatic suction cups 17 on the two feeding rings 18 are in the same position. Two push rods 20 are integrally formed and fixed to the side wall of the printing section 1. The two push rods 20 are horizontally arranged and positioned between the two feeding rings 18. A push block 19 is provided at the feed inlet. The push block 19 is used to push the fabric away from the electrostatic suction cups 17 on the side wall of the feeding ring 18. The push block 19 is slidably connected to one of the push rods 20, and a first push rod 21 is rotatably connected to the push block 19 via a rotating shaft. The first push rod 21 is rotatably connected to the second push rod 22 via a rotating shaft. The rotating shaft at the end of the second push rod 22 is coaxial with the feeding ring 18 and can rotate synchronously with the feeding ring 18. A transfer rod 30 is slidably arranged between the two push rods 20. An electrostatic suction cup 17 is fixed at the bottom of the transfer rod 30. At the same time, a pulling spring is provided on the push rod 20 to pull the transfer rod 30 toward the feeding ring 18. The push block 19 can push the transfer rod 30 to slide. Fabric is piled on the ground. During the rotation of the feeding ring 18, the fabric is attracted and rotated to the transfer rod 30, where it is attracted by the electrostatic suction cup 17. Under the action of the first push rod 21, the second push rod 22 and the push block 19, the transfer rod 30 is pushed, thereby driving the fabric to move and facilitating the transfer of the fabric to the printing section 1.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The printing section 1 is equipped with a conveyor belt 24, on which several electrostatic suction cups 17 are fixed. The electrostatic suction cups 17 adsorb the fabric, making it easy to clamp the fabric on the conveyor belt 24. A transverse roller is rotatably connected to the feed port via a rotating shaft. The axis of the transverse roller is parallel to the length of the conveyor belt 24. The transverse roller is used to stretch the fabric, reducing the possibility of the fabric folding on the conveyor belt 24. At the same time, the electrostatic suction cups 17 can clean the dust on the fabric, achieving the effect of cleaning the fabric.

[0034] Secondly, This application provides a printing process applicable to the above-mentioned high-definition fabric printing equipment, including the following steps; a. Transport the fabric to the bottom of the feeding ring 18. The feeding ring 18 rotates, and the electrostatic suction cup 17 on the rotating ring picks up the fabric for feeding. b. During the rotation of the fabric, it is blocked by the push rod 20 and transferred to the electrostatic chuck 17 on the transfer rod 30. Under the action of the first push rod 21 and the second push rod 22, the fabric is transferred to the conveyor belt 24. c. The fabric is printed in the printing section 1; d. The fabric enters the first drying section 3 under the action of the conveyor belt 24 and is held by the moving part 5. As the moving part 5 moves, the fabric moves in the first drying section 3 and undergoes initial drying. e. The moving part 5 moves the fabric from the first drying part 3 to the second drying part 4 for secondary drying. f. Once drying is complete, unload the material.

[0035] The implementation principle of a high-definition fabric printing equipment and printing process according to an embodiment of this application is as follows: The fabric is transported to the bottom of the feeding ring 18. The feeding ring 18 rotates, and the electrostatic suction cup 17 on the rotating ring adsorbs the fabric for feeding. During the rotation of the fabric, it is blocked by the push rod 20 and transferred to the electrostatic suction cup 17 on the transfer rod 30. Under the action of the first push rod 21 and the second push rod 22, the fabric is transferred to the conveyor belt 24. The fabric is printed in the printing section 1. Under the action of the conveyor belt 24, the fabric enters the first drying section 3 and is clamped by the moving part 5. With the movement of the moving part 5, the fabric moves in the first drying section 3 and undergoes initial drying. After the moving part 5 moves the fabric in the first drying section 3, it is transferred to the second drying section 4 for secondary drying. After drying is completed, the fabric is unloaded.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
