Description

Technical Field

[0001] This invention belongs to the field of printing technology, and more specifically, relates to a low-wastewater printing device and printing process for fabrics. Background Technology

[0002] Printing is a technique that prints patterns or designs onto textiles or other materials. It typically uses dyes, inks, or other pigments to print patterns onto the surface of the material. Printing can be divided into many different types, including screen printing, digital printing, and water printing. Water printing can be further subdivided into various types based on different techniques and effects. One type is marbling, which is a technique that uses dyes to draw patterns and then transfers them onto paper or fabric. Through the mass transfer properties of the ink mixed with water, the pattern texture is displayed on the paper or fabric, creating a unique artistic effect.

[0003] 1. In the use of existing equipment, in order to avoid excessive dispersion of dye in water, it is usually necessary to use a baffle to set the size between the printing area and the clear water area according to the size of the printed fabric. Currently, existing equipment generally uses the method of manually adjusting the baffle to adjust the size, which is not convenient.

[0004] 2. When using existing devices, ink and water are usually filled inside before watermarking. However, since the main component of the ink is a thickener, and the watermarking process is often not a sealed space, impurities can easily mix into the water over time. These impurities will suspend in the water, form flocculent matter, and adhere to the inner wall of the watermarking device, making it inconvenient to clean.

[0005] 3. Existing equipment typically divides the printing area into a printing area and a water cleaning area, but only uses baffles to separate the two areas without effectively separating them. Therefore, once flocculent matter is generated in the water, it can easily be distributed in various parts of the printing and water cleaning areas. Since the fabric after water printing often needs to be simply washed in the water cleaning area to remove excess dye, flocculent matter can easily adhere to the fabric, affecting its appearance and quality. Therefore, water needs to be changed, resulting in excessively high frequency of wastewater discharge and insufficient environmental friendliness. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a low-wastewater fabric printing device and printing process.

[0007] A low-wastewater fabric printing device includes a water printing device body, wherein fixed blocks are symmetrically fixedly installed on the upper end of the water printing device body, and a lead screw is rotatably installed between each group of fixed blocks.

[0008] The water-printing device is symmetrically and fixedly installed with an integrated automatic spacing adjustment and filtration mechanism on the side wall of the main body.

[0009] The automatic spacing adjustment and filtration integrated mechanism includes motors, with the output shafts of two motors fixedly installed to lead screws. The water-printing device body has symmetrically opened sliding grooves, both located below the lead screws. Transmission blocks are threaded onto the circumferential surfaces of both lead screws. Slider blocks are fixedly installed at the lower ends of both transmission blocks, and both sliders are slidably installed in the sliding grooves. A baffle is fixedly installed between the two transmission blocks, with first scrapers symmetrically fixedly installed at the lower ends of the baffles. Both first scrapers are in contact with the inner wall of the water-printing device body. The automatic spacing adjustment and filtration integrated mechanism also includes a first rectangular plate, a first filter screen, a first straight groove, a first limiting groove, a first limiting block, a first square bar, a second rectangular plate, a second filter screen, a second scraper, a second straight groove, a second limiting groove, a second limiting block, a second straight bar, a third rectangular plate, and a third filter screen.

[0010] Preferably, the first rectangular plate is fixedly installed inside the body of the water-printing device, the first filter screen is fixedly installed inside the first rectangular plate, two first straight grooves are symmetrically opened inside the first rectangular plate, both of the first straight grooves are located below the first filter screen, two sets of first limiting grooves are opened on the side wall of the first straight groove, and each first limiting block is slidably installed inside the first limiting groove.

[0011] Preferably, both first square bars are fixedly installed between the first limiting blocks, both first square bars are slidably installed with the first straight groove, the second rectangular plate is fixedly installed between the first square bars, the second filter screen is fixedly installed inside the second rectangular plate, the second filter screen is located below the first filter screen, both second scrapers are fixedly installed at the lower end of the second rectangular plate, and both second scrapers are in contact with the inner wall of the water printing device body.

[0012] Preferably, the two second straight grooves are symmetrically formed inside the second rectangular plate, both of the two second straight grooves are located below the second filter screen, both sets of the second limiting grooves are formed on the side wall of the second straight grooves, each of the second limiting blocks is slidably installed inside the second limiting groove, the two second straight bars are fixedly installed between the second limiting blocks, the two second straight bars are slidably installed with the second limiting groove, the third rectangular plate is fixedly installed between the second straight bars, the third filter screen is fixedly installed inside the third rectangular plate, and the two second straight bars, the third rectangular plate, and the third filter screen are all fixedly installed with the baffle.

[0013] A processing technology for a low-wastewater fabric printing device includes the following steps;

[0014] SI: When using it, first fill the inside of the water printing device with the prepared ink and water. Then, the inside of the water printing device will be divided into two areas by the baffle. The side closer to the motor with the baffle as the boundary is the printing area, and the side farther away from the motor with the baffle as the boundary is the clear water area. Then, the size of the printing area and the clear water area can be adjusted according to the size of the fabric to be processed.

[0015] S2: When it is necessary to adjust the size of the printing area and the clear water area, first turn on the motor so that the motor drives the two lead screws to rotate in the fixed block. At the same time, the lead screws will have a threaded transmission with the transmission block, so that the two transmission blocks drive the slider to slide towards the motor side in the slide groove. Since the second straight bar, the third rectangular plate and the third filter screen are connected to the baffle, the baffle will generate a radial force at this time, so that the baffle pulls the second straight bar, the third rectangular plate and the third filter screen to slide in the second limiting groove. At this time, the movement of the second straight bar will also drive the second limiting block to slide towards the motor side in the second limiting groove. When the second limiting block slides to the end of the second straight groove, the second limiting block will generate a radial force on the second rectangular plate as a whole, so that the second rectangular plate drives the first square bar and the first limiting block to slide in the first limiting groove and the first straight groove. After the adjustment is completed, the motor can be turned off.

[0016] S3: Then the staff can drip the dye into the printing area in layers, and then use a comb or needle to outline the pattern. Then the fabric can be covered in the printing area. After the printed fabric is removed from the printing area, the surface needs to be simply washed with water in the clean water area to make the pattern clear and bright. Then it can be dried.

[0017] S4: When it is necessary to clean the inner wall of the water-based printing device, the motor can be started directly, so that the lead screw can be threadedly driven with the baffle again. At this time, the baffle will drive the first scraper and the second scraper on the second rectangular plate to scrape the inner wall of the water-based printing device, thereby cleaning the flocculent material adhering to the inner wall of the water-based printing device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, by turning on the motor, the motor drives the lead screw to rotate in the fixed block and to have a threaded transmission with the transmission block. This causes the two transmission blocks to drive the slider to slide towards the motor side in the groove, thereby automatically completing the spacing between the printing area and the clear water area in the water printing device body, which is quite convenient.

[0020] In this invention, by setting an integrated automatic spacing adjustment and filtration mechanism, the baffle can separate the printing area and the clear water area, so that the subsequent printing can be separated. The water in the clear water area can be filtered by the first filter, the second filter and the third filter respectively, so as to avoid flocculent matter in the water being located in various positions of the water printing device body, thereby reducing the need for wastewater replacement and increasing environmental friendliness.

[0021] In this invention, when the baffle moves, it pulls the second straight bar, the third rectangular plate, and the third filter screen to slide within the second limiting groove. The movement of the second straight bar also causes the second limiting block to slide towards the motor side within the second limiting groove. When the second limiting block slides to the end of the second straight groove, it generates a radial force on the second rectangular plate, causing the second rectangular plate to slide the first square bar and the first limiting block within the first limiting groove and the first straight groove. This allows the filter effect to be consistently provided to the clean water area when adjusting the spacing between the printing area and the clean water area, increasing practicality.

[0022] In this invention, when the motor is started, the lead screw will once again engage with the baffle through a threaded transmission, which will cause the baffle to drive the first scraper and the second scraper on the second rectangular plate to scrape against the inner wall of the water-printing device body, thereby cleaning the flocculent material adhering to the inner wall of the water-printing device body. Then, the staff can discharge the water to the designated sewage treatment system to complete the wastewater cleaning, which is quite convenient.

[0023] In this invention, when the motor is turned on, the lead screw will engage in threaded transmission with the transmission block, causing the two transmission blocks to drive the slider to slide towards the motor side within the groove, thereby providing additional limiting and support and increasing stability.

[0033] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The present invention provides a low-wastewater fabric printing device, including a water printing device body 11, with fixed blocks 12 symmetrically fixedly installed on the upper end of the water printing device body 11, and a lead screw 13 rotatably installed between each group of fixed blocks 12.

[0035] The water-printing device body 11 is symmetrically and fixedly equipped with an integrated automatic spacing adjustment and filtration mechanism on its side wall.

[0036] The automatic spacing adjustment and filtration integrated mechanism includes motors 14, with the output shafts of both motors 14 fixedly installed to lead screws 13. The water-printing device body 11 has symmetrically arranged sliding grooves 15, both located below the lead screws 13. Transmission blocks 16 are threaded onto the circumferential surfaces of both lead screws 13. Slider blocks 17 are fixedly installed at the lower ends of both transmission blocks 16, and both sliders 17 are slidably installed with the sliding grooves 15. A baffle 18 is fixedly installed between the two transmission blocks 16, with first scrapers 19 symmetrically fixedly installed at the lower ends of the baffle 18. Both first scrapers 19 are slidably installed within the water-printing device body 11. The wall is fitted together. By turning on the motor 14, the motor 14 drives the lead screw 13 to rotate in the fixed block 12 and engages in threaded transmission with the transmission block 16. This causes the two transmission blocks 16 to drive the slider 17 to slide towards the motor 14 side in the slide groove 15. This can automatically complete the spacing between the printing area and the clear water area in the water printing device body 11, which is more convenient. When the motor 14 is turned on, the lead screw 13 will engage in threaded transmission with the transmission block 16, causing the two transmission blocks 16 to drive the slider 17 to slide towards the motor 14 side in the slide groove 15, thereby providing additional limit and support and increasing stability.

[0037] The automatic spacing adjustment and filtration integrated mechanism also includes a first rectangular plate 21, a first filter screen 22, a first straight groove 23, a first limiting groove 24, a first limiting block 25, a first square bar 26, a second rectangular plate 27, a second filter screen 28, a second scraper 29, a second straight groove 31, a second limiting groove 32, a second limiting block 33, a second straight bar 34, a third rectangular plate 35, and a third filter screen 36. The first rectangular plate 21 is fixedly installed inside the water-printing device body 11, and the first filter screen 22 is fixedly installed inside the first rectangular plate 21. Two first straight grooves 23 are symmetrically formed inside the first rectangular plate 21, both located below the first filter screen 22. Two sets of first limiting grooves 24 are formed on the sidewalls of the first straight grooves 23. Each first limiting block 25 is slidably installed inside the first limiting groove 24. Two first square bars 26 are fixedly installed between the first limiting blocks 25, and both first square bars 26 are slidably installed with the first straight grooves 23. A second rectangular plate 27 is fixedly installed between the first square bars 26. A second filter screen 28 is fixedly installed inside the second rectangular plate 27. The second filter screen 28 is located below the first filter screen 22, and the two second scrapers 29 are fixedly installed at the lower end of the second rectangular plate 27. The two second scrapers 29 are attached to the inner wall of the water-printing device body 11. By setting an automatic adjustment spacing and an integrated filtration mechanism, the baffle 18 can separate the printing area and the clear water area, so that the subsequent printing can be separated. The water in the clear water area can be filtered by the first filter screen 22, the second filter screen 28 and the third filter screen 36 respectively, so as to prevent flocculent matter in the water from being located in various positions of the water-printing device body 11, thereby reducing wastewater replacement and increasing environmental protection. When the motor 14 is started, the screw 13 will once again be threaded to the baffle 18, so that the baffle 18 will drive the first scraper 19 and the second scraper 29 on the second rectangular plate 27 to scrape the flocculent matter adhering to the inner wall of the water-printing device body 11, thereby cleaning the flocculent matter adhering to the inner wall of the water-printing device body 11. Then, the staff can discharge the water to the designated sewage treatment system to complete the wastewater cleaning, which is quite convenient.

[0038] Two second straight grooves 31 are symmetrically formed inside the second rectangular plate 27. Both second straight grooves 31 are located below the second filter screen 28. Two sets of second limiting grooves 32 are formed on the sidewalls of the second straight grooves 31. Each second limiting block 33 is slidably installed inside the second limiting groove 32. Two second straight bars 34 are fixedly installed between the second limiting blocks 33 and slidably installed with the second limiting grooves 32. A third rectangular plate 35 is fixedly installed between the second straight bars 34. A third filter screen 36 is fixedly installed inside the third rectangular plate 35. The two second straight bars 34, the third rectangular plate 35, and the third filter screen 36 are all fixedly installed with the baffle 18. When the baffle 18 moves... At this time, the baffle 18 pulls the second straight bar 34, the third rectangular plate 35 and the third filter screen 36 to slide in the second limiting groove 32. The movement of the second straight bar 34 will also drive the second limiting block 33 to slide together towards the motor 14 side in the second limiting groove 32. When the second limiting block 33 slides to the end of the second straight groove 31, the second limiting block 33 will generate a radial force on the second rectangular plate 27 as a whole, so that the second rectangular plate 27 drives the first square bar 26 and the first limiting block 25 to slide in the first limiting groove 24 and the first straight groove 23. In this way, when adjusting the spacing between the printing area and the clear water area, the clear water area can always be provided with a filtering effect, increasing practicality.

[0039] Working principle:

[0040] The first step is to fill the water printing device body 11 with the prepared ink and water. Then, the inside of the water printing device body 11 will be divided into two areas by the baffle 18. The side closer to the motor 14 with the baffle 18 as the boundary is the printing area, and the side away from the motor 14 with the baffle 18 as the boundary is the clear water area. The size of the printing area and the clear water area can then be adjusted according to the size of the fabric being processed.

[0041] The second step involves adjusting the dimensions of the printing area and the clear water area. First, the motor 14 is turned on, causing the two lead screws 13 to rotate within the fixed block 12. Simultaneously, the lead screws 13 engage with the transmission block 16 via a threaded connection, causing the two transmission blocks 16 to slide the slider 17 towards the motor 14 within the groove 15. Since the second straight bar 34, the third rectangular plate 35, and the third filter screen 36 are connected to the baffle 18, the baffle 18 will generate a radial force, causing it to pull the second straight bar 34 and the third rectangular plate... 35 and the third filter screen 36 slide in the second limiting groove 32. At this time, the movement of the second straight bar 34 will also drive the second limiting block 33 to slide together in the second limiting groove 32 towards the motor 14 side. When the second limiting block 33 slides to the end of the second straight groove 31 side, the second limiting block 33 will generate a radial force on the second rectangular plate 27 as a whole, so that the second rectangular plate 27 drives the first square bar 26 and the first limiting block 25 to slide in the first limiting groove 24 and the first straight groove 23. After the adjustment is completed, the motor 14 can be turned off.

[0042] The third step is for the staff to drip the dye into the printing area in layers, then use a comb or needle to outline the pattern, and then cover the printing area with the fabric. After the printed fabric is removed from the printing area, it needs to be rinsed with water in the clean water area to make the pattern clear and bright, and then it can be dried.

[0043] Third, when it is necessary to clean the inner wall of the water-printing device body 11, the motor 14 can be started directly, so that the lead screw 13 can once again drive the baffle 18. At this time, the baffle 18 will drive the first scraper 19 and the second scraper 29 on the second rectangular plate 27 to scrape the inner wall of the water-printing device body 11, thereby cleaning the flocculent material adhering to the inner wall of the water-printing device body 11.

[0044] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and to design various embodiments with various modifications suitable for a particular purpose.
