First, the fabric is placed under the printing assembly. The output end of the hydraulic cylinder 11 drives the mold frame 12 to press down, so that the printing assembly is pressed on the fabric. The flow control mechanism controls a small amount of dye to enter the extrusion box 15 through multiple feed holes 16 for temporary storage, and then the flow control mechanism drives the dye temporarily stored in the extrusion box 15 through the leakage plate 14 on the four support columns 13 to the printing assembly. A small amount of dye is enough to print the current fabric, which plays the role of quantitative dye printing on the fabric, thereby replacing the traditional printing device with a large amount of accumulated dye, reducing the color difference caused by fabric printing, and improving the effect of fabric printing.

[0032] The flow control mechanism includes an electric cylinder 2, an extrusion plate 21, a feed trough 22, a rubber block 23 and a feed trough assembly; the electric cylinder 2 is fixedly connected to the top inner wall of the extrusion box 15; the extrusion plate 21 is fixedly connected to the output end of the electric cylinder 2, and the extrusion plate 21 slides in contact with the inner wall of the extrusion box 15; a plurality of feed troughs 22 are provided on the leakage plate 14, and a plurality of feed troughs 22 are located below the extrusion plate 21; the rubber block 23 is fixedly connected to the inner wall of the feed trough 22, and a plurality of leakage holes are provided on the rubber block 23, and the plurality of leakage holes can be opened when the dye is squeezed by the extrusion plate 21, and the plurality of leakage holes can be closed when the extrusion plate 21 is reset. Block the dye in the feed trough 22; the feed assembly is arranged at the end of the printing base 1, and the feed assembly is used to control the dye to be fed into the extrusion box 15; when controlling the dye for printing on the cloth, the feed assembly is used to feed the dye into the extrusion box 15, and part of the dye is temporarily stored between the extrusion plate 21 and the leakage plate 14. At this time, multiple leakage holes are in a closed state, and the output end of the electric cylinder 2 drives the extrusion plate 21 to squeeze the temporarily stored dye, and the dye squeezes open the multiple leakage holes at the rubber block 23. The multiple leakage holes are not shown in the figure. The multiple leakage holes are ordinary holes, and the dye falls from the multiple feed troughs 22, which plays a role in quantitatively dropping the dye for printing.

[0033] like Figure 1 , Figure 2 and Figure 4As shown, the unloading assembly includes a support frame 3, a storage box 31, a flow hole 32 and a plug 33; the support frame 3 is fixedly connected to the end of the printing base 1; the storage box 31 is fixedly connected to the support frame 3, and the storage box 31 is sleeved on the extrusion box 15; a plurality of flow holes 32 are opened on the inner wall of the storage box 31, the flow holes 32 are arranged corresponding to the feed holes 16, and a one-way valve is installed on the inner wall of the flow hole 32; the plug 33 is installed on the storage box 31; when storing and unloading the dye for printing, the support frame 3 is used to support the storage box 31 and fix it at the extrusion box 15, the plug 33 is opened to add the dye into the storage box 31, and when the flow hole 32 coincides with the feed hole 16, the storage box 31 is opened. The dye stored inside the material box 31 can enter the extrusion box 15 for temporary storage through the flow hole 32 and the feed hole 16. As the output end of the hydraulic cylinder 11 drives the extrusion box 15 to slide down, the output end of the electric cylinder 2 drives the extrusion plate 21 to squeeze the dye temporarily stored in the extrusion box 15 out of the print. In the process of the extrusion plate 21 squeezing the dye, due to the presence of the one-way valve, the dye can only be discharged from multiple discharge troughs 22. The one-way valve is not shown in the figure. The one-way valve is a one-way flow valve in the prior art, which plays a role in storing and discharging printing dyes. At the same time, when the extrusion box 15 slides down, the extrusion box 15 can misalign the feed hole 16 with the flow hole 32, and the extrusion box 15 achieves blocking of the flow hole 32.

[0034] like Figures 1 to 3 As shown, the printing assembly includes a mold plate 4, an electric slider 41 and a two-way scraper 42; the mold plate 4 is fixedly connected to the inner wall of the bottom end of the mold frame 12; the electric slider 41 is slidably connected to the inner wall of the end of the mold frame 12; the two-way scraper 42 is fixedly connected to the bottom end of the electric slider 41, and the two-way scraper 42 fits the end of the mold plate 4; when printing cloth, the cloth is sent to the bottom end of the mold plate 4, and the output end of the hydraulic cylinder 11 drives the mold plate 4 to press on the cloth, and a small amount of dye is discharged to the end of the mold plate 4, and then the electric slider 41 drives the two-way scraper 42 to slide and print the cloth, which has the effect of printing the cloth. The mold plate 4 and the leakage plate 14 can be replaced according to different printing styles, so as to print different patterns on different cloths. At the same time, relying on the double shovels on both sides of the two-way scraper 42, the dye at the end of the mold plate 4 can be printed in two directions.

[0035] like Figure 1 and Figure 2 As shown, the inner wall of the printing base 1 is connected to a conveyor belt 5 through the rotation of a servo motor; a plurality of metal sheets 51 are fixedly connected to the end of the conveyor belt 5, and the material of the plurality of metal sheets 51 is a soft metal material; when printing cloth, the cloth is placed on the metal sheet 51, and the servo motor drives the conveyor belt 5 to rotate on the inner wall of the end of the printing base 1, and the conveyor belt 5 drives the plurality of metal sheets 51 to transport, thereby playing the role of transporting and printing multiple pieces of cloth. The plurality of metal sheets 51 are made of soft metal material, and can cooperate with the mold plate 4 to print cloth, thereby improving the effect of cloth printing.

[0036] like Figures 1 to 3 As shown, a drying box 6 is fixedly connected to one end of the printing base 1, and a steam groove is opened at the bottom of the drying box 6; a steam engine 61 is fixedly connected to the end of the drying box 6, and the output end of the steam engine 61 is connected to the steam groove; after the cloth is printed, the cloth is sent to the bottom of the drying box 6, and the steam engine 61 works to generate steam, and the steam is passed into the steam groove of the drying box 6. The steam gathered in the steam groove dries the printed cloth, thereby achieving the effect of drying the printed cloth.

[0037] The side of the mold frame 12 away from the drying box 6 is fixedly connected to a connecting plate 7; the side of the connecting plate 7 away from the mold frame 12 is fixedly connected to a pressing plate 71; before printing on the cloth, since some cloths are prone to wrinkles, the hydraulic cylinder 11 is used to drive the mold frame 12 to slide down, and the mold frame 12 simultaneously drives the pressing plate 71 on one side of the connecting plate 7 to press down, and the pressing plate 71 tightly presses the cloth, making the cloth smoother and reducing the influence of wrinkles on printing.

[0038] A connecting pipe 8 is fixedly connected to the outside of the drying box 6, and one end of the connecting pipe 8 away from the drying box 6 is fixedly connected to the pressing plate 71; a plurality of air holes are opened at the bottom end of the pressing plate 71, and the plurality of air holes can be connected to the steam tank through the connecting pipe 8; when the pressing plate 71 presses the cloth before printing, the steam is generated by the steam engine 61, and the steam enters the steam tank and gathers, and part of the steam is passed to the pressing plate 71 through the connecting pipe 8. As the pressing plate 71 presses the cloth, the plurality of air holes spray steam onto the cloth. The plurality of air holes are not shown in the figure, and the plurality of air holes are used to discharge steam, which plays a role in ironing the cloth.

[0039] like Figure 5 As shown, a method for printing fabric is provided, wherein the method adopts the fabric printing device described above for processing, and the steps of the method are as follows:

[0040] S1: First, the cloth is placed on the metal sheet 51 at the head of the printing base 1, and the servo motor drives the conveyor belt 5 to rotate and convey the cloth on the metal sheet 51. The cloth is first sent to the bottom end of the pressing plate 71, and part of the steam generated by the steam engine 61 is sent to the pressing plate 71 through the connecting pipe 8. The hydraulic cylinder 11 drives the mold plate 4 on the mold frame 12 to slide down, and the pressing plate 71 is pressed on the cloth for ironing;

[0041] S2: After the cloth is ironed by the pressing plate 71, the ironed cloth is sent to the bottom of the mold plate 4, the hydraulic cylinder 11 drives the mold frame 12 to slide down and press the ironed cloth, the electric cylinder 2 drives the squeezing plate 21 to squeeze the dye temporarily stored in the squeezing box 15, the dye is squeezed from the multiple feeding grooves 22 of the leakage plate 14 and falls to the end of the mold plate 4, the electric slider 41 drives the bidirectional scraper 42 to scrape the dye to print the cloth, after the cloth printing is completed, the hydraulic cylinder 11 drives the mold frame 12 to reset, and part of the dye stored in the storage box 31 flows into the squeezing box 15 through the flow hole 32 and the feed hole 16 for temporary storage;

[0042] S3: The printed fabric is then sent to the bottom of the drying box 6, and the steam generated by the steam engine 61 is gathered in the steam tank. The steam gathered in the steam tank dries the printed fabric. Finally, the dried fabric is collected by the tail of the printing base 1, and the fabric printing is completed.

[0043] The leaking plate 14 and the mold plate 4 in S2 can be replaced with corresponding models according to different patterns printed on the fabric, and the multiple feed slots 22 opened on the leaking plate 14 are offset from the printed pattern on the mold plate 4.

[0044] Working process: When using the fabric printing device to print fabric, the printing base 1 serves as the main structure of the fabric printing device. First, the fabric is placed under the printing component. The output end of the hydraulic cylinder 11 drives the mold frame 12 to press down, so that the printing component is pressed on the fabric. The flow control mechanism controls a small amount of dye to enter the extrusion box 15 through multiple feed holes 16 for temporary storage, and then the flow control mechanism drives the dye temporarily stored in the extrusion box 15 through the leakage plate 14 on the four support columns 13 to the printing component. A small amount of dye is enough to print the current fabric, which plays a role in quantitative dye printing on the fabric, thereby replacing the traditional printing device with a large amount of accumulated dye, reducing the color difference caused by fabric printing, and improving the effect of fabric printing; when controlling the dye for fabric printing, the unloading component is used to unload the dye into the extrusion box 15, and part of the dye is temporarily stored between the extrusion plate 21 and the leakage plate 14. At this time, the multiple leakage holes are in a closed state, and the output end of the electric cylinder 2 drives the extrusion plate 21 The temporarily stored dye is squeezed, and the dye squeezes open the multiple leakage holes on the rubber block 23, and the dye falls from the multiple feeding grooves 22, which plays a role in quantitatively dropping the dye for printing; when the dye for printing is stored and discharged, the storage box 31 is supported and fixed at the squeezing box 15 by the support frame 3, and the plug 33 is opened to add the dye into the storage box 31. When the flow hole 32 coincides with the feed hole 16, the dye stored in the storage box 31 can enter the squeezing box 15 through the flow hole 32 and the feed hole 16. As the output end of the hydraulic cylinder 11 drives the extrusion box 15 to slide down, the output end of the electric cylinder 2 drives the extrusion plate 21 to squeeze the temporarily stored dye in the extrusion box 15 out of the printing. During the process of the extrusion plate 21 squeezing the dye, due to the presence of the one-way valve, the dye can only be discharged from multiple discharge grooves 22, which plays a role in storing and discharging the printing dye. At the same time, when the extrusion box 15 slides down, the extrusion box 15 can misalign the feed hole 16 with the flow hole 32, and the extrusion box 15 can achieve the blocking of the flow hole 32;

[0045] When printing on the cloth, the cloth is sent to the bottom end of the mold plate 4, and the output end of the hydraulic cylinder 11 drives the mold plate 4 to press on the cloth, and a small amount of dye is discharged to the end of the mold plate 4. Then the electric slider 41 drives the two-way scraper 42 to slide and print the cloth, which has the effect of printing on the cloth. The mold plate 4 and the leakage plate 14 can be replaced according to different printing styles, which plays the role of printing different patterns on different cloths. At the same time, relying on the double shovels on both sides of the two-way scraper 42, the dye at the end of the mold plate 4 can be printed in two directions;

[0046] When printing on cloth, the cloth is placed on the metal sheet 51, and the conveyor belt 5 is driven by the servo motor to rotate on the inner wall of the end of the printing base 1. The conveyor belt 5 drives the multiple metal sheets 51 to transport, which plays the role of transporting and printing multiple pieces of cloth. The multiple metal sheets 51 are made of soft metal material and can cooperate with the mold plate 4 to print on the cloth, thereby improving the effect of cloth printing;

[0047] After the cloth is printed, the cloth is sent to the bottom of the drying box 6, and the steam engine 61 is operated to generate steam, and the steam is passed into the steam tank of the drying box 6. The steam gathered in the steam tank dries the printed cloth, which has the effect of drying the printed cloth; before the cloth is printed, since some cloth is prone to wrinkles, the hydraulic cylinder 11 is used to drive the mold frame 12 to slide down, and the mold frame 12 simultaneously drives the pressing plate 71 on one side of the connecting plate 7 to press down, and the pressing plate 71 tightly presses the cloth, making the cloth flatter and reducing the influence of wrinkles on printing; when the pressing plate 71 presses the cloth before printing, the steam engine 61 is used to generate steam, and the steam enters the steam tank and gathers, and part of the steam is passed to the pressing plate 71 through the connecting pipe 8. As the pressing plate 71 presses the cloth, multiple pores spray steam onto the cloth, which has the effect of ironing the cloth.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
