Description

Technical Field

[0001] This utility model relates to the field of inkjet printing winding technology, and in particular to a high-definition inkjet printing winding automatic alignment device. Background Technology

[0002] High-definition inkjet printing is a printing process that relies on high-precision inkjet technology. Using specialized inkjet printing equipment, prepared dyes or inks are precisely sprayed into the surface of substrates such as fabrics and films in the form of tiny droplets to form preset patterns and colors. This process is widely used in the textile and apparel, home decoration, and advertising printing fields. It can achieve clear presentation of complex patterns with high pattern resolution and good color reproduction, while reducing dye waste and pollution in the production process. At the same time, it also has flexible production characteristics, allowing for quick switching between different patterns to meet the needs of small-batch and personalized production, effectively improving the quality and production efficiency of printed products. Automated winding of high-definition inkjet printing is a key step in the high-definition inkjet printing production process. It refers to the process of automatically collecting and winding the printed substrate after the printing operation is completed. In this step, the equipment needs to neatly wind the continuously output printing substrate onto the winding roller according to the set speed and tension, without the need for manual intervention in the winding operation. Its core purpose is to connect the printing process with subsequent processing or storage, and to ensure that the printed substrate does not wrinkle or break during the winding process, thus maintaining the integrity of the substrate. While existing high-definition inkjet printing rewinding devices can drive the rewinding roller to rotate via a drive motor, pulling the printed substrate from the printing machine output to the rewinding roller to complete the winding, thus avoiding the problems of low efficiency and high labor intensity of manual rewinding to some extent, in actual operation, the existing devices rely solely on a single guide roller to guide the substrate and adjust the winding tension through a fixed tension spring. The guide roller position is fixed and cannot be adjusted according to the substrate width. The elastic deformation range of the tension spring is limited, making it difficult to adapt to the winding requirements of substrates with different thicknesses and materials. This results in uneven distribution of the substrate on the rewinding roller, and the final roll has uneven edges, affecting the substrate cutting and use in subsequent processing and reducing the overall product qualification rate.

The front and rear sides of the sliding groove 202 are provided with guide grooves 2112, which can serve as the track for the movement of the guide blocks 2111. Specifically, the printing machine 1 is the core operating component, used to complete the inkjet printing work. The discharge chute 4 on its front side provides a channel for conveying the printed material, ensuring that the material can smoothly enter the subsequent winding stage. The mounting brackets 5 fixedly connected to the left and right ends of the front side of the printing machine 1 are the supporting frame of the overall device, providing a mounting carrier for the alignment mechanism 2 and the tension mechanism 3. When the motor 6 on the top left side of the mounting bracket 5 is working, its output end passes through the mounting bracket 5 and drives the rotating rod 7 to rotate. The left and right ends of the outer wall of the rotating rod 7 are slidably connected to the sliding plate 204, which can help maintain the stability of the sliding plate 204 during operation. To prevent the sliding plate 204 from shifting and affecting the alignment effect, the motor 8 at the bottom left side of the left mounting bracket 5, after starting, drives the winding rod 9 to rotate through the mounting bracket 5. The winding rod 9 is responsible for winding the printed material after alignment and tension adjustment. The alignment mechanism 2 at the top of the mounting bracket 5 is used to ensure the alignment of the material during winding. The horizontal plate 201 is fixed to the top of the adjacent side of the mounting bracket 5 on the left and right sides, providing a mounting base for other components of the alignment mechanism 2. The sliding groove 202 at its bottom is the track for the sliding block 203 to move. The top of the sliding block 203 rotates with the positioning bolt 2101. The connection and positioning bolt 2101 can cooperate with multiple positioning holes 2102 opened on the top left and right sides of the horizontal plate 201. By tightening the positioning bolt 2101, the position of the sliding block 203 is fixed. Multiple guide blocks 2111 fixed on the front and rear sides of the sliding block 203 can be embedded into the guide grooves 2112 opened on the front and rear sides inside the sliding groove 202 to ensure that the sliding block 203 does not deviate when moving along the sliding groove 202.

Rotating the threaded rod 206 can drive the threaded block 207 to move up and down. The U-shaped frame 208, which is fixed on the adjacent side of the threaded block 207, adjusts its height with the threaded block 207. Multiple rollers 209, which are rotatably connected to the upper and lower sides inside the U-shaped frame 208, contact the material and guide the material to be transported smoothly to avoid deviation. The tension mechanism 3 at the bottom front end of the mounting frame 5 is used to adjust the tension when the material is wound up to prevent the material from breaking or wrinkling and to ensure the winding quality.

[0018] Reference Figure 2 and Figure 5The tension mechanism 3 includes two long plates 301, which provide mounting support for other components of the tension mechanism 3. The opposite sides of the two long plates 301 are fixedly connected to the bottom of adjacent sides of the mounting frame 5, which can firmly fix the long plates 301 to the mounting frame 5. Each of the adjacent sides of the two long plates 301 is provided with a moving groove 302, which can serve as a track for the moving block 304. The front and rear sides of the interior of the two moving grooves 302 are fixedly connected with telescopic rods 303. The telescopic rods 303 can adjust the position of the moving block 304 by telescopic movement. The front end of each of the two telescopic rods 303 is fixedly connected to a moving block. 304, the movable block 304 can drive the hollow column 305 to move synchronously. The hollow column 305 is fixedly connected to the adjacent side of the two movable blocks 304. The hollow column 305 can provide sliding space for the connecting block 306. The connecting block 306 is slidably connected inside the two hollow columns 305. The connecting block 306 can drive the tension rod 307 to adjust the height. The tension rod 307 is rotatably connected to the adjacent side of the two connecting blocks 306. The tension rod 307 can contact the material to adjust the winding tension. A limit component 308 is provided on the front side of the hollow column 305. The limit component 308 can fix the position of the connecting block 306. The limiting component 308 includes two limiting blocks 3081. The limiting blocks 3081 can be fixed to the connecting block 306 by snapping into the limiting groove 3082. The rear sides of the two limiting blocks 3081 are slidably connected to the front side of the connecting block 306, so that the limiting blocks 3081 can move with the connecting block 306 and achieve limiting. The front sides of the two hollow columns 305 are provided with multiple limiting grooves 3082. The limiting grooves 3082 can cooperate with the limiting blocks 3081 to provide multiple limiting positions. Specifically, in the tension mechanism 3, two long plates 301 serve as basic support components, with their opposite sides fixedly connected to the bottom of adjacent sides of the mounting frame 5, providing a stable mounting platform for other components of the tension mechanism 3 and ensuring that the structure does not shake during tension adjustment. The movable groove 302 opened on the adjacent side of the long plate 301 is the track for the movable block 304, providing space for adjusting the position of the movable block 304. The telescopic rod 303 fixedly connected to the front and rear sides inside the movable groove 302 can drive the movable block 304 fixedly connected at the front end to move back and forth along the movable groove 302 through telescopic movement, thereby adjusting the position of subsequent components to adapt to the tension adjustment requirements under different working conditions. The hollow column 305 fixedly connected to the adjacent side of the movable block 304 provides installation and sliding space for the connecting block 306, and also supports the connecting block 306. The connecting block 306, which is slidably connected inside the hollow column 305, can slide up and down along the hollow column 305. The tension rod 307, which is rotatably connected to its adjacent side, adjusts its height and position as the connecting block 306 moves. The tension rod 307 contacts the printing material and changes the force on the material by changing its own position, thereby realizing the tension adjustment when the material is rolled up, preventing the material from wrinkling due to being too loose or breaking due to being too tight. In the limiting component 308 set on the front side of the hollow column 305, the rear side of the two limiting blocks 3081 is slidably connected to the front side of the connecting block 306. When the connecting block 306 is adjusted to a suitable position, the limiting blocks 3081 are inserted into the corresponding limiting grooves 3082 opened on the front side of the hollow column 305, which can fix the position of the connecting block 306, so that the tension rod 307 maintains a stable tension state and ensures that the tension adjustment effect is continuously effective.

[0019] Reference Figure 3 and Figure 5 The right side of the printing machine 1 is provided with a heat dissipation vent 10, which can accelerate the heat dissipation inside the printing machine 1. The heat dissipation vent 10 is rotatably connected to multiple rotating plates 11. The rotating plates 11 can be rotated to adjust the opening and closing size of the heat dissipation vent 10 to control the heat dissipation intensity. The two moving blocks 304 are respectively slidably connected to the interior of the corresponding moving grooves 302, which allows the moving blocks 304 to move stably along the moving grooves 302. The size of the moving blocks 304 and the moving grooves 302 are matched to prevent the moving blocks 304 from shifting or shaking during movement. The bottom of the two positioning bolts 2101 respectively penetrates the interior of the corresponding positioning holes 2102. The positioning bolts 2101 and the positioning holes 2102 can initially fix the position of the sliding block 203. The bottom ends of the positioning bolts 2101 are threaded to the top of the corresponding sliding block 203, which can firmly connect the positioning bolts 2101 and the sliding block 203, thereby stabilizing and fixing the sliding block 203. Specifically, the heat dissipation vent 10 on the right side of the printing machine 1 can accelerate the dissipation of heat inside the printing machine 1, preventing the machine from overheating due to prolonged operation and affecting its operational stability and service life. Multiple rotating plates 11 inside the heat dissipation vent 10 can be rotated to adjust the opening and closing size of the heat dissipation vent 10 to adapt to the heat dissipation requirements under different working conditions. Two moving blocks 304 are slidably connected to the corresponding moving grooves 302, and the size of the moving blocks 304 matches that of the moving grooves 302. This design ensures that the moving blocks 304 do not shift when sliding in the moving grooves 302, ensuring that the moving blocks 304 drive the subsequent components to adjust their positions smoothly, providing a stable foundation for tension adjustment. The bottoms of the two positioning bolts 2101 pass through the corresponding positioning holes 2102, and the bottom ends of the positioning bolts 2101 are threaded to the top of the corresponding sliding blocks 203. By tightening the positioning bolts 2101, the sliding blocks 203 can be firmly fixed on the horizontal plate 201, preventing the sliding blocks 203 from shifting when the device is working, thereby ensuring the stable alignment effect of the alignment mechanism 2.

[0020] Working principle: When using this device, the printing machine 1 first completes the printing operation. The printed material is then conveyed from the discharge chute 4 at the front of the printing machine 1 to the winding mechanism area. In the alignment adjustment stage, the horizontal plate 201 provides the mounting base for the alignment mechanism 2. The sliding groove 202 at its bottom is the track for the sliding block 203 to move. The guide blocks 2111 on the front and rear sides of the sliding block 203 are embedded in the guide grooves 2112 on the front and rear sides of the sliding groove 202. When it is necessary to adjust the alignment position according to the material width, the guide blocks 2111 slide along the guide grooves 2112 to ensure that the sliding block 203 moves smoothly and does not deviate. The bottom of the sliding block 203 is fixed to the sliding plate 204. The movement of the sliding block 203 drives the sliding plate 204 to move synchronously until the U-shaped frame 208 on the sliding plate 204 fits against both sides of the material. Then, the threaded rod 206 at the top of the sliding plate 204 is rotated. The threaded rod 206 passes through the groove 205 and engages with the threaded block 207. The rotation of the threaded rod 206 causes the threaded block 207 to move up and down, thereby adjusting the height of the U-shaped frame 208. This allows multiple rollers 209 on the upper and lower sides of the U-shaped frame 208 to contact the material surface. After adjusting the position, the bottom of the positioning bolt 2101 is aligned with the positioning hole 2102 at the top of the horizontal plate 201 and tightened. The sliding block 203 is fixed by the positioning bolt 2101, completing the alignment position locking. The material moves along the rollers 209 during conveying to avoid deviation. Finally, it enters the winding stage. The motor 28 at the bottom left side of the left mounting frame 5 is started. Its output end passes through the mounting frame 5 and drives the winding rod 9 to rotate. The winding rod 9 winds up the material that has been aligned and tension adjusted. At the same time, the motor 16 at the top left side of the left mounting frame 5 is started. Its output end passes through the mounting frame 5 and drives the rotating rod 7 to rotate. The outer wall of the rotating rod 7 is slidably connected to the sliding plate 204 to help maintain the stability of the sliding plate 204 and ensure that the alignment state remains unchanged during the winding process. Furthermore, when it is necessary to adjust the front and rear position of the tension rod 307 according to the material conveying path, the movable groove 302 on the adjacent side of the long plate 301 comes into play. The telescopic rod 303 fixed on the front and rear sides inside the movable groove 302 is telescopic, which drives the movable block 304 fixed at the front end to slide back and forth along the movable groove 302. The hollow column 305 fixed on the adjacent side of the movable block 304 moves synchronously with the movable block 304, thereby driving the connecting block 306 slidably connected inside the hollow column 305 and the tension rod 307 rotatably connected on the adjacent side of the connecting block 306 to adjust the front and rear position, ensuring that the tension rod 307... 07 can make precise contact with materials. If the height of the tension rod 307 needs to be adjusted to suit materials of different thicknesses, the connecting block 306 can be pushed to slide up and down inside the hollow column 305. The movement of the connecting block 306 drives the tension rod 307 to rise and fall synchronously. After adjusting to a suitable height, the rear sides of the two limiting blocks 3081 in the limiting component 308 are aligned with the corresponding limiting grooves 3082 on the front side of the hollow column 305 and inserted. The position of the connecting block 306 is fixed by the limiting blocks 3081, so that the tension rod 307 maintains a stable tension state and avoids problems caused by unstable tension during material conveying.
