Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing technology, and in particular to a device for aligning and calibrating printed patterns on textile fabrics. Background Technology

[0002] The textile fabric printing pattern alignment calibration device is a core auxiliary equipment used in the textile printing and dyeing field to improve printing accuracy. It is applied in flat screen printing, rotary screen printing and digital heat transfer processes. The device integrates a guide transmission mechanism, a real-time detection module and an automatic adjustment component. During operation, the detection module captures the positioning marks on the fabric and transfer paper, compares them with the preset pattern positions to generate a deviation signal, and then the adjustment component drives the guide roller and the fabric conveying platform to make a slight displacement.

[0003] The textile fabric printing pattern alignment calibration device achieves precise alignment between the printed pattern and the fabric texture and multi-color overprint layers, reducing defects such as pattern misalignment and ghosting caused by fabric stretching, equipment vibration, and paper feed deviation, and improving the consistency and pass rate of printed products. However, the guide roller is prone to wear and eccentricity. After long-term friction with the fabric and transfer paper, scratches and dents will appear on the surface of the guide roller, resulting in eccentric rotation of the roller body, which causes wrinkles in the material during transmission. Summary of the Invention

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 3 and Figure 4An embodiment of this utility model provides a textile fabric printed pattern alignment calibration device, including a guide roller 1. An eccentric clamping mechanism 2 is installed on the left side of the inner wall of the guide roller 1 to prevent displacement of the guide roller 1. A screw moving mechanism 3 is installed at the lower end of the bottom wall of the guide roller 1 for cleaning. The eccentric clamping mechanism 2 includes a fixed disc 201, which is installed on the left side of the inner wall of the guide roller 1. Multiple rectangular blocks 202 are fixedly connected at equal intervals on the left side of the outer wall of the fixed disc 201. A drive assembly 203 is installed on the left side of the inner wall of the guide roller 1. The drive assembly 203 includes a fixing screw 2031, which is installed on the left side of the inner wall of the guide roller 1. A turntable 2033 is fixedly connected on the right side of the outer wall of the fixing screw 2031. Multiple fan-shaped grooves 2034 are equidistantly opened in the middle of the inner wall of the turntable 2033. A sliding rod 2032 is slidably connected in the middle of the inner wall of the fan-shaped grooves 2034.

[0032] Specifically, rotating the fixing screw 2031 causes the turntable 2033 to start rotating. The rotation of the turntable 2033 causes the sliding rods 2032 to slide. When all the sliding rods 2032 slide together to a certain position in the fan-shaped groove 2034 opened in the turntable 2033, the other end of the sliding rod 2032 begins to support the fixed disk 201 and play a fixing role. The restriction of each sliding rod 2032 prevents the fixed disk 201 from rotating and displacing. Finally, the support of the fixed disk 201 prevents the guide roller 1 from being eccentric.

[0033] Reference Figure 1 and Figure 5 The screw moving mechanism 3 includes a fixed plate 301, which is installed on the lower end of the bottom wall of the guide roller 1. Long rods 305 are fixedly connected to the front and rear ends of the right side of the outer wall of the fixed plate 301. A sliding block 304 is slidably connected to the left side of the outer wall of the long rod 305. A dust collector 302 is fixedly connected to the middle of the top wall of the sliding block 304. An execution component 303 is installed on the lower end of the bottom wall of the guide roller 1. The execution component 303 includes a motor 3031, which is installed on the lower end of the bottom wall of the guide roller 1. A helical gear 3033 is fixedly connected to the output end of the motor 3031. A worm gear 3032 is meshed with the bottom wall of the helical gear 3033.

[0034] Specifically, the starting motor 3031, model 14H030H, works by inputting three-phase AC power to rotate the rotor. The rotor outputs mechanical energy, which drives the helical gear 3033 to rotate. Through the meshing force between the long rods 305 on both sides and the helical gear 3033 and the worm 3032, the helical gear 3033 begins to move along the direction of the worm 3032. The long rods 305 and the worm 3032 are fixed by the fixing plate 301. The movement of the helical gear 3033 drives the sliding block 304 to move along the direction of the long rod 305, and finally drives the dust collector 302 to move, thus performing multi-directional dust removal and cleaning of the equipment.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A support plate 9 is installed on the right side of the outer wall of the guide roller 1. An adjuster 8 is installed on the upper end of the top wall of the guide roller 1. A control box 7 is installed on the left side of the outer wall of the guide roller 1. A display screen 6 is fixedly connected to the upper front side of the outer wall of the control box 7. A switch 4 is rotatably connected to the right front side of the outer wall of the display screen 6. A heat sink 5 is installed in the middle of the top wall of the control box 7.

[0036] Specifically, by turning switch 4 to turn on the device, the device enters the operating state. After the guide roller 1 starts, it guides the textile fabric to roll along the prescribed path, ensuring the alignment and calibration of the printed pattern. The control box 7 contains a control circuit based on an STM32 series microcontroller, which is responsible for the operation control and signal processing of the entire device. The heat sink 5 dissipates the heat generated inside the control box 7 in real time to ensure the normal operation of the circuit. The display screen 6 is used to display the fabric transmission status and calibration parameters, enabling timely detection. During the fabric transmission process, the photoelectric sensor continuously detects the edge position of the textile fabric and the preset positioning marks, and then... The detection signal is transmitted to the control circuit in the control box 7. When the detection signal indicates that the fabric position is off, it will cause the printed pattern to be misaligned. The control circuit in the control box 7 immediately analyzes and processes the offset signal according to the preset calibration algorithm, and then outputs a control command to the regulator 8. The regulator 8 is a MINAS-A6. After receiving the control command, the regulator 8 starts to operate. The screw nut mechanism converts the rotational motion into linear motion. By precisely adjusting the position and angle of the guide roller 1, the deviation of the fabric transmission direction is corrected, so that the area to be printed on the fabric corresponds to the printing component, and finally the alignment and calibration of the printed pattern on the textile fabric is achieved.

[0037] Working principle: Rotating the fixing screw 2031 causes the turntable 2033 to start rotating. The rotation of the turntable 2033 causes the sliding rods 2032 to slide. When all the sliding rods 2032 slide together to a certain position in the fan-shaped groove 2034 opened in the turntable 2033, the other end of the sliding rod 2032 begins to support the fixed disk 201 and play a fixing role. The restriction of each sliding rod 2032 prevents the fixed disk 201 from rotating and displacing. Finally, the support of the fixed disk 201 prevents the guide roller 1 from being eccentric.

[0038] The motor 3031 is started, and the rotor drives the helical gear 3033 to rotate. Through the meshing force between the long rods 305 on both sides and the helical gear 3033 and the worm 3032, the helical gear 3033 begins to move along the direction of the worm 3032. The long rods 305 and the worm 3032 are fixed by the fixing plate 301. The movement of the helical gear 3033 drives the sliding block 304 to move along the direction of the long rod 305, and finally drives the dust collector 302 to move, thus performing multi-directional dust removal and cleaning of the equipment.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
