A scraper is installed at the bottom of the guide components. A pressure sensor is installed between the guide components and a pressure sensor.

[0007] Preferably, when the squeegee is pressed down, it contacts the printing screen in the printing frame. When the squeegee moves back and forth in the printing frame, it causes the dye to pass through the holes in the printing screen and print the dye onto the brushed fabric.

[0008] Preferably, the guide assembly includes a sleeve and a guide rod that moves within the sleeve, the sleeve being fixed to the bottom of the movable plate, and one end of the guide assembly being mounted on the top of the scraper.

[0009] Preferably, the lifting assembly further includes a telescopic drive component for driving the moving plate to move up and down. The telescopic drive component is respectively disposed at the bottom of both ends of the moving plate. The telescopic drive component causes the moving plate to move down so that the bottom of the scraper contacts the printing screen in the printing frame.

[0010] Preferably, the lateral movement component includes a support frame mounted on the main body, pulleys rotatably mounted at both ends of the support frame, a belt sleeved between the pulleys, a sliding member fixed to one end of the belt, a slide rail slidably connected to the sliding member on the support frame, the sliding member being fixedly connected to the bottom of the telescopic drive component, and a second rotary drive component for driving the pulleys to rotate is also mounted on one side of the support frame.

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] Reference Figures 1-4 As shown, this utility model provides: a brushed fabric printing device, including a main body 1 and a flat printing device 16 mounted on the main body 1. The flat printing device 16 is used to print dye onto the brushed fabric. The flat printing device 16 is the core component of the device, specifically used to evenly print carefully mixed dye onto the brushed fabric, giving the fabric rich patterns and colors. The flat printing device 16 includes a dye printing assembly 161 for storing dye and printing it onto the brushed fabric. The dye printing assembly 161 includes a printing frame 1614 that can be lifted and lowered. The printing frame 1614 is also provided with a detachable printing screen. The detachable printing screen not only facilitates the replacement of printing screens with different patterns, but also facilitates cleaning and maintenance, extending the service life of the device. The flat printing device 16 includes a horizontal moving assembly 162 and a lifting assembly 163. The horizontal moving assembly 162 causes the lifting assembly 163 to reciprocate linearly. The lifting assembly 163 is provided with a moving plate 1632 that can move up and down. The horizontal moving assembly 162 drives the lifting assembly 163 through a precision transmission mechanism. The component 163 moves in a reciprocating linear motion in the horizontal direction. The moving plate 1632 moves back and forth after contacting the printing screen, allowing the printed pattern to be evenly and continuously covered on the entire fabric. Guide components 1635 are also provided on both sides of the bottom of the moving plate 1632. These guide components 1635 not only provide stable support for the moving plate 1632 but also ensure the precise guidance of the squeegee 1634 during the printing process. The squeegee 1634 is installed at the bottom of the guide components 1635, and a pressure sensor 1633 is installed between the guide components 1635 and the pressure sensor 1633. The squeegee 1634 helps to evenly apply the dye to the fabric, forming a clear printed pattern. Furthermore, the combined use of the guide components 1635 and the pressure sensor 1633 enables real-time monitoring and adjustment of the printing pressure, effectively avoiding printing quality problems caused by excessive or insufficient pressure.

[0026] By installing a pressure sensor 1633 between the moving plate 1632 and the scraper 1634, when the scraper 1634 contacts the printing frame 1614, the scraper 1634 has an upward force. The pressure sensor 1633 detects the pressure of the scraper 1634 and detects the printing pressure in real time. By controlling the printing pressure, the dye is evenly and clearly attached to the brushed fabric.

[0027] When the scraper 1634 is pressed down, it contacts the printing screen in the printing frame 1614. When the scraper 1634 moves back and forth in the printing frame 1614, it causes the dye to pass through the holes in the printing screen and print the dye onto the brushed fabric. The guide assembly 1635 includes a sleeve and a guide rod that moves in the sleeve. The sleeve is fixed to the bottom of the moving plate 1632, and one end of the guide assembly 1635 is installed on the top of the scraper 1634.

[0028] The lifting assembly 163 also includes a telescopic drive component 1631 for driving the moving plate 1632 to move up and down. The telescopic drive component 1631 is respectively disposed at the bottom of both ends of the moving plate 1632. The telescopic drive component 1631 causes the moving plate 1632 to move down, so that the bottom of the scraper 1634 contacts the printing screen in the printing frame 1614. When the telescopic drive component 1631 is activated and drives the moving plate 1632 to move down, the bottom of the scraper 1634 will be in close contact with the printing screen in the printing frame 1614. This design ensures that the dye can be evenly applied to the fabric to form a clear printed pattern.

[0029] The lateral movement assembly 162 includes a support frame 1621 mounted on the main body 1. Pulleys 1622 are rotatably mounted at both ends of the support frame 1621, and a belt 1624 is sleeved between the pulleys 1622. A sliding member 1625 is fixed to one end of the belt 1624. The support frame 1621 is slidably connected to the sliding member 1625 via a slide rail. The sliding member 1625 is fixedly connected to the bottom of the telescopic drive assembly 1631. A second rotary drive assembly 1623 is also mounted on one side of the support frame 1621 to drive the pulleys 1622. The second rotary drive assembly 1623 provides stable power to ensure smooth operation of the pulleys 1622 and the belt 1624. By precisely controlling the rotational speed and direction of the second rotary drive assembly 1623, precise control of the moving speed and direction of the sliding member 1625 can be achieved, thereby meeting different printing requirements.

[0030] The dye printing assembly 161 includes a reciprocating moving assembly for moving the printing frame 1614 up and down. The reciprocating moving assembly includes a lead screw 1612, which is movably disposed on the front and rear sides of the main body 1 via bearing seats. A first rotary drive 1611 is mounted on the main body 1. The output end of the first rotary drive 1611 is fixedly connected to one end of the lead screw 1612. A moving part 1613 is movably disposed on the lead screw 1612. The top of the moving part 1613 is fixedly connected to the bottom of the printing frame 1614. The reciprocating moving assembly also includes a limiting assembly that enables the printing frame 1614 to move up and down.

[0031] In use, by activating the first rotary drive 1611, the first rotary drive 1611 causes the lead screw 1612 to rotate, which in turn causes the moving part 1613 to move up and down. The moving part 1613 causes the printing frame 1614 to come into contact with the brushed fabric, so that the dye can be printed on the brushed fabric.

[0032] refer to Figure 5 and Figure 6 As shown, a conveying device 15 is also provided directly above the top of the main body 1. A drying device 14 for drying the dye on the brushed fabric is also provided on one side of the top of the conveying device 15. Guide devices 13 for guiding the brushed fabric are also provided on both sides of the top of the main body 1. An unwinding device 12 for unwinding the brushed fabric is provided at one end of the main body 1. The unwinding device 12 is used to unwind the brushed fabric to be printed, providing continuous fabric input for the conveying device 15. A winding device 11 for winding the brushed fabric is also provided on the other side of the top of the main body 1. The winding device 11 is used to wind up the brushed fabric after printing and drying, which is convenient for subsequent processing and storage. The drying device 14 includes a drying chamber 141, which is located on the side near the winding device 11. Several temperature sensors 142 are installed on the two side walls inside the drying chamber 141. The temperature sensors 142 are used to monitor the temperature inside the drying chamber 141 in real time to ensure the temperature control accuracy during the drying process. Several filter elements 143 are detachably installed on the top of the temperature sensors 142. A fan 144 is installed inside the drying chamber 141 at a position corresponding to the filter elements 143. A heater for heating air is also installed between the fan 144 and the filter elements 143. The filter elements 143 are used to filter impurities and dust in the air, protecting the fan 144 and the heater from contamination, and preventing dust from contaminating the brushed fabric.

[0033] The drying chamber 141 is equipped with a temperature sensor 142 for detecting temperature. The air is heated by a heater inside the drying chamber 141, and the hot air is circulated by a fan 144 and blown onto the brushed fabric, so that the brushed fabric is dried quickly.

[0034] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
