Description

Technical Field

[0001] This utility model relates to the field of inkjet printing technology, and in particular to an inkjet printing device for precise silk positioning. Background Technology

[0002] Silk inkjet printing is a printing process that applies digital inkjet technology to silk fabrics. With its precise pattern presentation and environmentally friendly characteristics, it has developed rapidly in the silk product manufacturing industry. Silk inkjet printing is based on digital image information, which converts the computer-designed pattern into an electrical signal to control the tiny nozzles in the printhead to spray ink droplets as needed. These ink droplets fall on the surface of the silk fabric, and through the superposition, penetration and drying of the ink droplets, a pattern with rich colors and delicate layers is formed.

[0003] A search revealed Chinese Patent Publication No. 221623353U, which discloses a printing positioning device for a digital printing machine, including a base plate. This utility model, through the setting of a positioning mechanism, allows for adjustment based on the size of the packaging box. Activating an electric push rod causes it to extend and retract, moving the positioning plates and changing the distance between the left and right positioning plates. When the positioning plates reach their respective positions, the electric push rod is deactivated. Rotating the lead screw then moves the moving sleeve, which in turn moves the positioning rod, changing the distance between the front and rear positioning rods. When the positioning rod reaches its corresponding position, the lead screw rotation stops. After adjustment, the packaging box is placed in the area formed by the positioning plates and rods for printing. The positions of the positioning plates and rods are easily adjustable, enabling the device to quickly position packaging boxes of different sizes, effectively expanding its applicability. However, in practical use, the positioning movement via the multi-functional moving sleeve, while corrected by a visual positioning system to compensate for mechanical errors, results in a high response delay. This affects high-speed printing and printing positioning accuracy, ultimately impacting the printing effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an inkjet printing device for precise silk positioning, which aims to improve the problem in the prior art where, although it can compensate for mechanical errors, the mechanism response delay is high, which affects high-speed printing and printing positioning accuracy, and thus affects the printing effect of the mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an inkjet printing device for precise silk positioning, comprising a frame, a vertical shell fixedly connected to the top wall of the frame, camera devices fixedly connected to the front ends of the left and right sides of the inner wall of the vertical shell, infrared laser displacement sensors fixedly connected to the left and right sides of the top wall of the frame, a fixing plate fixedly connected to the middle of the inner top wall of the frame, a driving device fixedly connected to the bottom wall of the fixing plate, a sliding block slidably connected to the bottom end of the driving device, printheads fixedly installed on the front and rear sides of the sliding block, two through slots opened in the middle of the top wall of the frame, a conveying device fixedly installed on the top of the inner wall of the frame, a polyurethane synchronous belt fixedly installed in the middle of the conveying device, multiple heat dissipation slots opened on the rear ends of the left and right sides of the vertical shell, and a drying mechanism provided on the rear side of the top wall of the frame.

[0006] The above technical solution enables the silk to be conveyed by a polyurethane synchronous belt under the conveying equipment. The height of the fabric is monitored in real time by a camera and laser sensor, which allows the sliding block to be driven at the bottom of the drive equipment. Multiple nozzles then carry out printing and dyeing work through an external pressure pump and pipeline, thus avoiding the reduction of printing speed and printing positioning accuracy.

[0007] As a further description of the above technical solution:

[0008] The drying mechanism includes a drying fan. The bottom wall of the drying fan is fixedly connected to the rear side of the top wall of the frame. The front left end of the drying fan is connected to an insulation pipe. The bottom end of the insulation pipe is connected to an annular spray pipe. The top wall of the annular spray pipe is fixedly connected to the rear side of the inner top wall of the vertical shell. The front right end of the drying fan is connected to a filter column. The left and right rear ends of the top wall of the frame are both fixedly connected to arc-shaped plates. Multiple guide shells are fixedly connected to one side of the arc-shaped plates.

[0009] The above technical solution allows the extracted airflow to remove impurities through filtration by the filter column. The airflow is then heated and transported by the drying fan, and subsequently sprayed through an annular nozzle to dry the printed silk. After spraying, the airflow is guided by the guide shell and discharged more quickly from the interior of the vertical shell through the heat dissipation groove, thus avoiding the situation where the dried hot airflow adheres to the inner wall of the vertical shell and forms water droplets that affect the silk printing.

[0010] As a further description of the above technical solution:

[0011] The drying mechanism also includes a rubber ring, the inner wall of which is fixedly connected to the middle of the outer wall of the insulation pipe.

[0012] The above technical solution improves the protection of the connection point of the insulated pipe by using a rubber ring.

[0013] As a further description of the above technical solution:

[0014] A control switch is fixedly connected to the front side of the frame. The control switch is electrically connected to the camera device, the infrared laser displacement sensor, the conveying device, the driving device, and the drying fan.

[0015] The above technical solution enables the device to be turned on and off by connecting the control switch.

[0016] As a further description of the above technical solution:

[0017] Protective plates are fixedly connected to the left and right front ends of the shell, and each of the protective plates has a sloping surface on one side.

[0018] The above technical solution improves the protection effect on both sides of the protective shell by connecting the protective plate.

[0019] As a further description of the above technical solution:

[0020] Rubber rings are fixedly connected to the left and right sides of the outer wall of the conveying equipment, and the two rubber rings are symmetrically designed.

[0021] The above technical solution enables an increase in static friction on the silk through the connection of the rubber ring.

[0022] As a further description of the above technical solution:

[0023] The multiple nozzles are arranged at equal intervals, and the horizontal height of the multiple nozzles is the same.

[0024] The above technical solution enables the uniformity of spray printing to be improved by equidistantly arranging the nozzles.

[0025] As a further description of the above technical solution:

[0026] Two connecting seats are fixedly connected to each of the left and right sides of the frame, and a support column is fixedly connected inside each connecting seat.

[0027] The above technical solution improves the stability of the device during operation by connecting the connecting seat and the support column.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the silk can be conveyed by the polyurethane synchronous belt when the conveying equipment is started. With the camera capturing the feature points of the fabric edge, the fabric height is monitored in real time by the laser sensor, so that the sliding block can drive the nozzle to make fine adjustment of the displacement. Then, multiple nozzles pass through the through groove through the external pressure pump and pipe to carry out the printing and dyeing work, which avoids the situation that the high mechanism response delay will reduce the printing speed and printing positioning accuracy.

[0030] 2. In this utility model, by starting the drying fan, it can draw in outside air through the filter column, reducing the amount of air containing impurities entering the drying fan. The filtered air is then transported and sprayed through the annular nozzle. Subsequently, the sprayed air is guided by the guide shell and discharged more quickly from the interior of the vertical shell through the heat dissipation groove. This avoids the hot air after drying adhering to the inner wall of the vertical shell and forming water droplets that affect silk printing, thereby improving the printing quality.

The conveying device 10 is installed on the top of the inner wall of the frame 1. The polyurethane synchronous belt 11 is fixedly installed in the middle of the device. When the conveying device 10 starts to operate, it can drive the polyurethane synchronous belt 11 to rotate, thereby realizing the conveying of the silk fabric and smoothly and orderly conveying the fabric to the processing area below the printheads 9. Multiple heat dissipation slots 12 are opened on the left and right rear ends of the shell 3. These heat dissipation slots 12 can promote air circulation and dissipate the heat generated during the operation of the equipment in a timely manner.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The drying mechanism 2 includes a drying fan 201. The bottom wall of the drying fan 201 is fixedly connected to the rear side of the top wall of the frame 1. The left front end of the drying fan 201 is connected to an insulated pipe 202.

[0042] Specifically, the bottom wall of the drying fan 201 is fixed to the rear side of the top wall of the frame 1, providing stable support for the drying fan 201. The front left end of the drying fan 201 is connected to the heat-insulating pipe 202, which has a heat-insulating function to reduce heat loss of the heated airflow during transmission, ensuring that the airflow is transported at a higher temperature. The bottom end of the heat-insulating pipe 202 is connected to the annular nozzle 203, the top wall of which is fixed to the rear side of the inner top wall of the vertical shell 3, so that the heated airflow can be evenly output through the annular nozzle 203, and the silk being transported is dried with a suitable temperature and airflow distribution, thus achieving the purpose of drying the silk. The front right end of the drying fan 201 is connected to the annular nozzle 203. The filter column 207 is connected to the end of the drying fan 201. The filter column 207 is equipped with a filter device, which can filter and remove impurities from the external airflow drawn by the drying fan 201, so as to prevent impurities from entering the drying system with the airflow and affecting the drying effect or contaminating the silk. The left and right rear ends of the top wall of the frame 1 are respectively fixedly connected to the arc plate 204. Multiple guide shells 205 are fixed on one side of the arc plate 204. These arc plates 204 and guide shells 205 cooperate with each other to form a specific airflow guiding structure, which can guide the airflow generated after drying the silk, change the flow direction and path of the airflow, and make it exit the equipment more quickly, ensuring the circulation and renewal of air in the drying environment and maintaining the stability of the drying effect.

[0043] Reference Figure 1 , Figure 4 and Figure 5 The drying mechanism 2 also includes a rubber ring 206, the inner wall of which is fixedly connected to the middle of the outer wall of the insulation pipe 202; a control switch 14 is fixedly connected to the front side of the frame 1, and the control switch 14 is electrically connected to the camera device 4, the infrared laser displacement sensor 5, the conveying device 10, the driving device 7 and the drying fan 201 respectively; protective plates 13 are fixedly connected to the front ends of the left and right sides of the vertical shell 3, and a slope is provided on one side of each protective plate 13;

[0044] Specifically, the rubber ring 206 protects the connection of the insulation pipe 202. The control switch 14, which is electrically connected to the camera device 4, the infrared laser displacement sensor 5, the conveying device 10, the drive device 7, and the drying fan 201, can turn the equipment on and off. The protective plate 13 protects the front left and right sides of the shell 3.

[0045] Reference Figure 1 , Figure 2 and Figure 3Rubber rings 18 are fixedly connected to the left and right sides of the outer wall of the conveying equipment 10. Both rubber rings 18 are symmetrically designed. Multiple nozzles 9 are arranged at equal intervals and have the same horizontal height. Two connecting seats 15 are fixedly connected to the left and right sides of the frame 1. Support columns 16 are fixedly connected inside the connecting seats 15.

[0046] Specifically, the connection of the rubber ring 18 increases the static friction during silk conveying, thereby reducing slippage. The equidistant arrangement of multiple nozzles 9 improves the uniformity of printing spraying. The connection seat 15 and support column 16 enhance the stability of the device during operation.

[0047] Working principle: When in use, the conveyor 10 is started, allowing the silk to be conveyed through the polyurethane synchronous belt 11. This enables the camera 4 to capture the feature points of the fabric edge. Simultaneously, under the monitoring of the infrared laser displacement sensor 5, the fabric height is monitored in real time, which drives the drive device 7 to adjust the position of the sliding block 8. Subsequently, multiple printheads 9, through the opening of the slot 17, can be connected to external pressure pumps and pipelines to deliver ink, thereby completing the printing and dyeing work through the printheads 9. This avoids the situation of high mechanism response delay, thereby improving the printing speed and printing positioning accuracy.

[0048] Furthermore, by activating the drying fan 201, it can extract and filter outside air through the filter column 207, thereby reducing the amount of air containing impurities entering the drying fan 201 and protecting it. The filtered air is then transported and sprayed through the annular nozzle 203 to dry the printed silk, improving its drying efficiency. Subsequently, the sprayed air is guided by the guide shell 205 and discharged more quickly from the interior of the vertical shell 3 through the heat dissipation groove 12, thus preventing the dried hot air from adhering to the inner wall of the vertical shell 3 and forming water droplets, reducing the impact on silk printing and improving printing quality.
