The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0021] The sofa fabric printing device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1-Figure 5 As shown, the sofa fabric printing device of the embodiment of the present invention includes a workbench 1, two sets of brackets 2, a rolling mechanism 3, a printing machine 4, a guide roller 5 and an electric winder 6.

[0023] Two groups of brackets 2 are arranged side by side on the workbench 1, and the brackets 2 are U-shaped structures.

[0024] It should be noted that the workbench 1 can be composed of a board surface and four legs. The legs are arranged at the four corners of the bottom of the board surface to support the board surface. The bracket 2 is arranged side by side on the workbench 1 and can be connected to the workbench 1 through fasteners. The fasteners can be a combination of screws, bolts or nuts in combination with plate-like connectors. The U-shaped structure of the bracket 2 is for installing the rolling mechanism 3, which facilitates the structure to swing inside the bracket 2 for rolling.

[0025] The rolling mechanism 3 is arranged above the workbench 1 , and includes two sets of swing frames 31 , four pressing rods 32 , two rolling rollers 33 , four sets of pressing structures 34 and a swing driving structure 35 .

[0026] Among them, the two groups of swing frames 31 are respectively rotatably set in the two groups of brackets 2, the swing frames 31 are U-shaped structures, and the four pressing rods 32 are respectively inserted at the two ends of the two groups of swing frames 31, and the two rolling rollers 33 are respectively set under the swing frames 31, and the two ends of the two rolling rollers 33 are respectively rotatably connected to the other ends of the four pressing rods 32.

[0027] It can be understood that the swing frame 31 is rotatably connected to the bracket 2, allowing the swing frame 31 to swing at a certain angle in the bracket 2. The pressure rod 32 is inserted into the swing frame 31 and is rotatably connected to the rolling roller 33. Therefore, the swing frame 31 controls the rolling roller 33 to swing from the middle position between the brackets 2 toward the lower end and the bracket 2. The rolling roller 33 rolls the sofa fabric downward to remove wrinkles, thereby eliminating wrinkles that appear when the sofa fabric is printed.

[0028] The four groups of pressing structures 34 are respectively arranged on the four pressing rods 32 .

[0029] It can be understood that the pressing structure 34 is arranged on the pressing rod 32, and a part of the pressing rod 32 is inside the swing frame 31. Therefore, the pressing structure 34 can press and control the pressing rod 32 to move a certain distance outside the swing frame 31. After the swing frame 31 swings downward, the extension of the pressing rod 32 will control the rolling roller 33 to press on the sofa fabric, thereby fixing the sofa fabric while removing wrinkles.

[0030] The swing driving structure 35 is provided at one end of the two groups of brackets 2 .

[0031] It should be noted that the swing drive structure 35 is connected to the two groups of brackets 2 in order to control the swing frames 31 in the two groups of brackets 2 and realize the driving function of the swing frame 31 to swing.

[0032] The printing machine 4 is arranged between the two groups of brackets 2 .

[0033] It should be noted that the printing machine 4 can be composed of a digital printing machine and a pushing cylinder. The pushing cylinder can push the digital printing machine downward so that the digital printing machine can approach the sofa fabric for printing. It is set between the two groups of brackets 2 because the area where the sofa fabric is flattened and fixed is between the brackets 2, so the sofa fabric is printed in this area.

[0034] The guide roller 5 is arranged on the workbench 1 , and the guide roller 5 is located on one side of the printing machine 4 .

[0035] It can be understood that the guide roller 5 is a long roller shaft, which is used to guide the sofa fabric sent from the outside. The outside can be connected to an electric winding drum for winding the sofa fabric. The electric winding drum can release the wound sofa fabric and send it between the brackets 2 through the guide roller 5 for flattening and fixing.

[0036] The electric winder 6 is arranged on the workbench 1 , and the electric winder 6 is located on the other side of the printing machine 4 .

[0037] It should be noted that the electric reel 6 can be composed of a motor, a mounting frame and a reel. The reel is rotatably mounted on the mounting frame and is controlled to rotate by the motor. The motor controls the reel to rotate and reel up the printed sofa fabric.

[0038] Specifically, the relevant staff places the sofa fabric delivered from the outside onto the guide roller 5 for guidance and transportation. The conveying of the sofa fabric is suspended after passing through the two groups of brackets 2. The relevant staff operates the swing drive structure 35 to control the swing frame 31. The swing frame 31 starts to swing from the middle area between the brackets 2, driving the rolling roller 33 to swing downward. The rolling roller 33 presses the sofa fabric and rolls and flattens it by swinging.

[0039] After the rolling roller 33 swings to the bottom, the wrinkle removal work is completed. The pressing structure 34 presses the pressing rod 32, and the pressing rod 32 transmits the pressing force to the rolling roller 33. With the help of the pressing force, the rolling roller 33 fixes the sofa fabric.

[0040] The relevant staff operates the printing machine 4 to print the sofa fabric. After the printing is completed, the swing drive structure 35 is operated to control the rolling roller 33 to swing upward, release the fixation of the sofa fabric, continue to convey the sofa fabric, and fix the processed sofa fabric on the electric winder 6 for winding. Then the above operations are continued to print and wind the sofa fabric.

[0041] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the pressing structure 34 includes a spring damper 341 , a guide bar hole 342 and a guide plate 343 .

[0042] Among them, the spring damper 341 is arranged at one end of the pushing rod 32, the other end of the spring damper 341 is connected to the swing frame 31, the guide bar hole 342 is opened on the pushing rod 32, the guide plate 343 is arranged in the guide bar hole 342, and both ends of the guide plate 343 are connected to the swing frame 31.

[0043] It should be noted that the guide bar hole 342 is opened on the push rod 32, and there is a guide plate 343 inside it. The guide plate 343 can only move in the area constrained by the guide bar hole 342. The guide plate 343 is connected to the swing frame 31. Therefore, the guide bar hole 342 and the guide plate 343 play a role of restraint and limitation to prevent the push rod 32 from separating from the swing frame 31.

[0044] The spring damper 341 can be composed of a damper and a spring, and the two are connected to the pushing rod 32 and the swing frame 31, providing a pushing function for the pushing rod 32. After the pushing rod 32 swings downward, it presses against the sofa fabric. Under the force, the pushing rod 32 will move into the swing frame 31, and under the influence of the reaction force of the spring damper 341, the pushing rod 32 is controlled to firmly fix the sofa fabric at the bottom.

[0045] Specifically, the swing frame 31 swings downward, driving the pressure rod 32 and the rolling roller 33 thereon to swing downward. The rolling roller 33 continuously presses the sofa fabric downward. The downward pressing force controls the pressure rod 32 to move into the swing frame 31. The spring damper 341 provides a reaction force to push the pressure rod 32. The pressure rod 32 transmits the pushing force it receives to the rolling roller 33 to press the sofa fabric.

[0046] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, the swing drive structure 35 includes a drive bar box 351, two gears 352, two racks 353 and a connecting block 354.

[0047] Among them, the driving bar box 351 is arranged above the bracket 2, one end of the driving bar box 351 is connected to the two groups of brackets 2, two gears 352 are symmetrically arranged in the driving bar box 351, the two gears 352 are respectively connected to the two groups of swing frames 31, two racks 353 are respectively arranged at the top and bottom ends of the two gears 352, the gears 352 are meshed and connected with the racks 353, and a connecting block 354 is arranged between the two racks 353, and the top and bottom ends of the connecting block 354 are respectively connected to the two racks 353.

[0048] It should be noted that a motor can be provided on the driving bar box 351, and the motor can be connected to one of the gears 352 through a fastener. The motor can drive the gear 352 to rotate, and the gear 352 and the swing frame 31 can be connected through a rotating rod. The rotating rod is a rod-shaped structure, and its two ends can be connected to the gear 352 and the swing frame 31 through fasteners. The rotating rod is rotatably connected to the driving bar box 351 and the bracket 2.

[0049] The rack 353 and the connecting block 354 are in close contact with the inner wall of the driving bar box 351, ensuring that the two can only move horizontally and cannot turn over or rotate, thereby not affecting the driving.

[0050] It can be understood that one of the gears 352 is controlled by the motor to rotate and drive one of the swing frames 31 to swing, the gear 352 drives the rack 353 meshing with it, the rack 353 drives the other rack 353 to move through the connecting block 354, the other rack 353 drives another gear 352 to rotate, and the other gear 352 controls the swing of the other swing frame 31. The swing directions of the two groups of swing frames 31 under the control of this structure are opposite, which is more convenient for rolling and flattening the sofa fabric.

[0051] One end of the driving bar box 351 is connected to the printing machine 4.

[0052] It should be noted that the driving bar box 351 can be connected to the printing machine 4 through fasteners, mainly to support and fix the printing machine 4.

[0053] Specifically, when relevant staff need to roll, flatten and fix the sofa fabric, they need to control the swing frame 31 to swing, start the motor to drive one of the gears 352, and the gear 352 directly drives one of the swing frames 31 to swing, while driving one of the racks 353, the connecting block 354 and the other rack 353 to move synchronously. The other rack 353 drives the other gear 352 to rotate, driving the other swing frame 31 to swing synchronously, thereby completing the drive control of the swing frame 31.

[0054] In summary, the sofa fabric printing device of the embodiment of the present invention can roll and flatten the sofa fabric to eliminate wrinkles, while taking into account the effect of fixing the sofa fabric, and solve the problems affecting the printing integrity and printing effect.
