Description

Technical Field

[0001] The present application belongs to the technical field of textile printing equipment, and in particular, relates to a fabric printing machine. Background Art

[0002] Printing is a method of printing dyes or coatings onto fabrics to form patterns. Fabric printing is also called partial dyeing of fabrics. When the same dye is used for dyeing and printing, the properties of the chemical auxiliaries used are similar, the coloring mechanism of the dye is the same, and the fastness requirements of the dye on the fabric during wearing are the same.

[0003] The existing foreign patent with publication number KR102215616B1 discloses an automatic screen printing machine, including a frame, a screen frame, a screen mold, a printing unit, a driving unit, and the like.

[0004] Although the above-mentioned printing machine can realize automatic printing of fabrics, the fabrics are easily offset during movement, which easily leads to poor quality of printing on the fabrics. Improvements are proposed in this regard. Summary of the invention

[0005] The purpose of this application is to provide a fabric printing machine to address the above-mentioned technical problems, which can improve the movement stability of the fabric during the printing process and ensure the printing quality of the fabric.

[0006] The present application provides a fabric printing machine, including a printing machine body, wherein the printing machine body includes:

[0007] A movable frame, movably mounted on the printing machine body, wherein the movable frame is provided with a screen mold;

[0008] Scraper, movably mounted on the movable frame;

[0009] An adjusting mechanism for adjusting the position of the fabric;

[0010] A tension adjusting device, used for adjusting the tension of the fabric;

[0011] The detection mechanism is installed on the printing machine body;

[0012] The adjusting mechanism comprises a pressure roller and an adjusting roller. The adjusting roller is provided with a plurality of convex strips, and the convex strips are spirally wound on the adjusting roller. The pressure roller is provided with a lifting mechanism.

[0013] The screen mold is installed on a movable frame, and the fabric is printed by automatically controlling the movement of the scraper. The fabric is continuously moved on the printing machine body for printing. The fabric is easily offset in the width direction during movement, which reduces the quality of fabric printing. The adjustment mechanism is used to ensure the movement stability of the fabric. The detection mechanism is used to detect the boundary of the fabric. The detection mechanism uses a grating or an industrial camera. When the fabric is detected to be offset, the convex strip on the adjusting roller contacts the fabric. When the fabric moves forward, the fabric is adjusted and moved in the width direction when the adjusting roller rotates. The fabric is controlled to move to both sides by controlling the forward or reverse rotation of the adjusting roller. The pressure between the adjusting roller and the pressure roller is controlled by the lifting mechanism to improve the stability of the adjusting roller during adjustment.

[0014] Furthermore, the lifting mechanism comprises:

[0015] Lifting seat;

[0016] The stud is movably mounted on the printing machine body and connected to the lifting seat;

[0017] The guide column is movably mounted on the printing machine body and connected to the lifting seat;

[0018] A transmission rod provided with a first gear;

[0019] a second gear mounted on the stud;

[0020] The driving motor is installed and connected with the transmission rod.

[0021] The driving motor drives the transmission rod to rotate, the first gear is installed on the transmission rod, the first gear is meshed with the second gear, the first gear and the second gear both use bevel gears, when the transmission rod rotates, the driving stud rotates, the lifting seat is driven to be raised and lowered through the threaded pair connection between the stud and the lifting seat, when the fabric end needs to pass through the gap between the pressure roller and the adjusting roller, the pressure roller is adjusted to rise.

[0022] Furthermore, the lifting mechanism further comprises:

[0023] A movable seat, movably mounted in the lifting seat, and the movable seat is movably connected to the pressing roller;

[0024] A first spring is placed on both sides of the movable seat;

[0025] The pressure sensor is installed on the lifting seat and abuts against the first spring.

[0026] When the pressure roller descends to clamp the fabric with the adjusting roller, the movable seat is placed in the lifting seat and moves. The force acting on the pressure sensor by the first spring changes, so that the pressure detected by the pressure sensor changes, and the pressing strength between the pressure roller and the adjusting roller is detected.

[0027] Furthermore, the printing machine body is provided with a groove, the groove corresponds to the pressure roller, the adjusting roller is installed on the printing machine body, and part of the adjusting roller extends into the groove.

[0028] The groove makes the lowest point of the contact surface between the fabric and the pressing roller lower than the working table of the printing machine body, further improving the stability of the fabric during printing. The adjusting roller is installed on the printing machine body and partially extends into the groove, so that the adjusting roller can press the fabric together with the pressing roller.

[0029] Furthermore, the adjusting roller comprises:

[0030] The adjusting shaft is movably installed in the adjusting roller;

[0031] An adjusting disk, mounted on the adjusting shaft;

[0032] Wherein, the convex strip is provided with a driving part, and the adjusting disk is provided with a driving groove corresponding to the driving part.

[0033] The adjusting shaft is driven to rotate by a separate driving device installed in the adjusting roller, and the adjusting disk is installed and connected to the adjusting shaft. When the adjusting disk rotates, the convex strip is placed on the adjusting roller to move telescopically through the structure between the driving groove on the adjusting disk and the driving part on the convex strip. When the fabric moves stably without deviation, the convex strip is contracted into the adjusting roller, and the fabric does not need to be adjusted when it moves between the pressure roller and the adjusting roller.

[0034] Furthermore, the surface of the convex strip is provided with an anti-slip layer.

[0035] The anti-skid layer increases the friction between the convex strips and the fabric, and when the adjusting roller rotates to adjust the fabric, it has a more efficient and stable bonding with the convex strips. The anti-skid layer is made of anti-skid rubber, silicone, etc., and has a mesh structure to further increase the friction performance.

[0036] The beneficial effects of this application are:

[0037] 1. When the fabric moves forward, the adjusting roller rotates to adjust and move the fabric in the width direction. The fabric is moved to both sides by controlling the adjusting roller to rotate forward or reverse. The pressure between the adjusting roller and the pressure roller is controlled by the lifting mechanism to improve the stability of the adjusting roller during adjustment.

[0038] 2. The fabric boundary is detected by a detection mechanism, which uses a grating or an industrial camera.

[0039] 3. Through the structure between the driving groove on the adjusting disk and the driving part on the convex strip, the convex strip is controlled to be placed on the adjusting roller for telescopic movement. When the fabric moves stably without deviation, the convex strip is retracted into the adjusting roller. When the fabric moves between the pressure roller and the adjusting roller, there is no need to adjust and move. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] A movable frame 200 is movably mounted on the printing machine body 100, and the movable frame 200 is provided with a screen mold 210;

[0051] A scraper 220 is movably mounted on the movable frame 200;

[0052] An adjustment mechanism 300, used to adjust the position of the fabric;

[0053] A tension adjusting device, used for adjusting the tension of the fabric;

[0054] The detection mechanism 400 is installed on the printing machine body 100;

[0055] The adjusting mechanism 300 includes a pressure roller 310 and an adjusting roller 320 . The adjusting roller 320 is provided with a plurality of convex strips 321 . The convex strips 321 are spirally wound around the adjusting roller 320 . The pressure roller 310 is provided with a lifting mechanism 330 .

[0056] The screen mold 210 is installed on the movable frame 200. The movement of the scraper 220 is automatically controlled to print the fabric. The fabric is continuously moved on the printing machine body 100 for printing. The fabric is easily offset in the width direction during movement, which reduces the quality of fabric printing. The adjustment mechanism 300 is used to ensure the movement stability of the fabric. The detection mechanism 400 is used to detect the boundary of the fabric. The detection mechanism 400 uses a grating or an industrial camera. When the fabric is detected to be offset, the convex strip 321 on the adjusting roller 320 contacts the fabric. When the fabric moves forward, the adjusting roller 320 rotates to adjust the movement of the fabric in the width direction. The fabric is controlled to move to both sides by controlling the forward or reverse rotation of the adjusting roller 320. The pressure between the adjusting roller 320 and the pressure roller 310 is controlled by the lifting mechanism 330, so as to improve the stability of the adjusting roller 320 during adjustment.

[0057] Embodiment 2:

[0058] like Figure 1 , Figure 3 As shown, the embodiment of the present application provides a fabric printing machine. In addition to the above technical features, the lifting mechanism 330 further includes:

[0059] Lifting seat 331;

[0060] The stud 332 is movably mounted on the printing machine body 100 and connected to the lifting seat 331;

[0062] The transmission rod 334 is provided with a first gear 335;

[0063] A second gear 336 mounted on the stud 332;

[0064] The driving motor is installed and connected with the transmission rod 334.

[0065] The driving motor drives the transmission rod 334 to rotate, and the first gear 335 is installed on the transmission rod 334. The first gear 335 is meshed with the second gear 336. The first gear 335 and the second gear 336 both use bevel gears. When the transmission rod 334 rotates, the driving stud 332 rotates. The threaded pair between the stud 332 and the lifting seat 331 is connected to drive the lifting seat 331 to be raised and lowered. When the end of the fabric needs to pass through the gap between the pressure roller 310 and the adjustment roller 320, the pressure roller 310 is adjusted to rise.

[0066] Furthermore, the lifting mechanism 330 further includes:

[0067] A movable seat 337 is movably installed in the lifting seat 331, and the movable seat 337 is movably connected to the pressing roller 310;

[0068] The first spring 338 is placed on both sides of the movable seat 337;

[0069] The pressure sensor 339 is installed on the lifting seat 331 and abuts against the first spring 338 .

[0070] When the pressure roller 310 descends to clamp the fabric with the adjusting roller 320, the movable seat 337 is placed in the lifting seat 331 and moves. The force exerted by the first spring 338 on the pressure sensor 339 changes, so that the pressure detected by the pressure sensor 339 changes, and the pressing strength between the pressure roller 310 and the adjusting roller 320 is detected.

[0071] Furthermore, the printing machine body 100 is provided with a groove 500 , and the groove 500 corresponds to the pressure roller 310 . The regulating roller 320 is installed on the printing machine body 100 , and a part of the regulating roller 320 extends into the groove 500 .

[0072] The groove 500 makes the lowest point of the contact surface between the fabric and the pressing roller 310 lower than the working surface of the printing machine body 100, further improving the stability of the fabric during printing. The adjusting roller 320 is installed on the printing machine body 100 and partially extends into the groove 500, so that the adjusting roller 320 can press the fabric together with the pressing roller 310.

When the adjusting disk 323 rotates, the convex strip 321 is placed on the adjusting roller 320 for telescopic movement through the structure between the driving groove 325 on the adjusting disk 323 and the driving part 324 on the convex strip 321. When the fabric moves stably without deviation, the convex strip 321 is contracted into the adjusting roller 320, and there is no need to adjust the fabric when it moves between the pressure roller 310 and the adjusting roller 320.

[0079] Furthermore, an anti-slip layer 326 is provided on the surface of the convex strip 321 .

[0080] The anti-skid layer 326 increases the friction between the convex strip 321 and the fabric, so that when the adjusting roller 320 rotates to adjust the fabric, the anti-skid layer 326 is bonded to the convex strip 321 . The anti-skid layer 326 is made of anti-skid rubber, silicone, etc. The anti-skid layer 326 has a mesh structure to further increase the friction performance.
