Description

Technical Field

[0001] The invention relates to the technical field of textile printing industry, in particular to an environmentally friendly water-based ink printing supporting equipment for polyester webbing. Background Art

[0002] In the textile printing industry, polyester webbing, with its high strength and wear resistance, has become a key material for the production of clothing and luggage accessories. The environmentally friendly water-based inks that complement it, due to their low VOC emissions and biodegradability, have captured over 70% of the polyester webbing printing market. However, the smooth surface and poor porosity of polyester webbing prevent 45% of the environmentally friendly ink from adhering, resulting in residual ink. Direct discharge not only wastes raw materials but also pollutes the environment through pigment residue and acid-base imbalance, causing COD levels in water bodies to exceed standards by 65% ​​and color levels to exceed national standards by three times.

[0003] Currently, printing equipment is typically equipped with an open recovery tank to collect residual ink. This allows residual ink to remain in the tank for extended periods, causing the ink solvent to evaporate and dry out, and pigment particles to settle and accumulate, clogging the collection pipes. This also allows impurities such as dust and fibers to enter. Once the ink dries, the impurities mix with the ink, forming a complex contaminant that is difficult to separate. This impacts the stability and efficiency of separation equipment such as nano-ceramic membranes.

[0004] Therefore, we proposed a polyester webbing environmentally friendly ink printing equipment to solve the above problems. Summary of the Invention

It solves the problem that the recovery tank is an open structure, the residual ink in the recovery tank is retained for a long time, the ink solvent evaporates and dries up, the pigment particles precipitate and accumulate, which will clog the collection pipe, and it is easy for external dust, fiber and other impurities to mix in.

[0023] Compared with the existing technology, the environmentally friendly water-based ink printing equipment for polyester webbing has the following beneficial effects:

[0024] 1. The present invention uses a monitoring mechanism to enable the polyester webbing environmentally friendly water-based ink printing supporting equipment to monitor in real time how much residual ink has been collected. Through the sealing and hiding mechanism, the waste ink collection device can seal and store the residual ink, thereby avoiding the problem of long-term retention of residual ink in the waste ink collection tank, evaporation and drying of the ink solvent, and precipitation and accumulation of pigment particles, which will clog the collection pipeline.

[0025] 2. The present invention uses a filtering mechanism to enable the polyester webbing environmentally friendly water-based ink printing supporting equipment to filter out impurities in a timely manner, avoiding the accumulation of impurities during the sealing process of the residual water-based ink and clogging the pipeline. This not only helps to reduce the difficulty of subsequent separation, but is also more conducive to maintaining the original characteristics of the water-based ink, and can increase the quality and efficiency of residual water-based ink recovery.

A cutting plane 806 close to the second stainless steel woven mesh 609 is opened on the guide tube 805. The bearing plate 803 above the guide tube 805 is slidably connected to the arc surface of the guide tube 805, and the bearing plate 803 below the guide tube 805 is in contact with the cutting plane 806.

[0076] The anti-mixing structure 8 can block the corresponding backflushing hole 708 so that the backflushing mechanism 7 will not affect the first stainless steel woven mesh 608 or the second stainless steel woven mesh 609 during operation, thereby separating the filtering work from the backflushing work to ensure that the flushing water will not mix with the residual ink.

[0077] Please refer to Figure 3 and Figure 6 The slag discharge mechanism 9 includes a slag discharge bending plate 901 and a slag discharge pipe 903. The slag discharge bending plate 901 is connected to the inner wall of the temporary storage chamber 104. A collection chamber 902 is formed between the inner wall of the slag discharge bending plate 901 and the inner wall of the temporary storage chamber 104. The collection chamber 902 is connected to the leakage slit 602. The slag discharge pipe 903 is connected to the side of the waste ink temporary storage part 101 away from the collection chamber 902 and is connected to the collection chamber 902.

[0078] The mixture of flushing water and impurities can be discharged through the slag discharge mechanism 9, thereby improving the practicality of the polyester ribbon environmentally friendly water-based ink printing supporting equipment.

[0079] Working principle: First, the residual ink drops into the waste ink collection tank 102, and then the residual ink slides down along the inner wall of the waste ink collection tank 102, and then the residual ink passes through the storage slit 302 and collects in the sealing groove 307 with the opening facing upward, and then the liquid level probe 202 constantly monitors the liquid level inside the sealing groove 307 and sends the height information to the controller 309. When the height value reaches the preset value inside the controller 309, the controller 309 controls the output shaft of the sealing motor 304 to rotate half a circle, and then the sealing motor 304 rotates half a circle with the sealing column 306 through the docking shaft head 305, and then the vacant sealing groove 307 that originally opened downward becomes open upward, and the lead piston 403 inside it falls back into the sealing groove 307 under the action of gravity, making room for collecting the residual ink. During the falling process, the lead piston 403 The air below it is pressed and discharged through the constant pressure short hole 502, the constant pressure channel 501, and the constant pressure small hole 503, and the corresponding limiting short rope 402 is bent and stored in the accommodating groove 401; the sealing groove 307, which originally opened upward and contained residual ink, becomes open downward, and then the residual ink inside the sealing groove 307 flows downward under the action of gravity. At the same time, the lead piston 403 inside the sealing groove 307 slides downward under the action of gravity, pushing the residual ink downward, and the residual ink is discharged faster and cleaner, while also playing a role of pressurization. In this process, the downward movement of the lead piston 403 will suck external air into the sealing groove 307 through the constant pressure small hole 503, the constant pressure channel 501, and the constant pressure short hole 502, thereby avoiding the formation of negative pressure inside the sealing groove 307 and improving the effective work of the lead piston 403;

[0080] Then the residual ink passes through the blanking slit 303 downward and falls on the first stainless steel woven mesh 608, and then the residual ink penetrates downward under the action of gravity and pressure difference, while impurities are trapped on the top surface of the first stainless steel woven mesh 608, achieving the purpose of filtration, and then the residual ink falls on the corresponding cavity plate 707 and the top surface of the elastic plug 804, and then the residual ink flows under the action of the liquid level difference, and then the residual ink passes through the corresponding leakage opening 611 and slides along the surface of the guide slope 702 to the inside of the temporary storage chamber 104, the temporary storage chamber 104 temporarily stores the residual ink, and then as the use time increases, the first stainless steel woven mesh 608 is filled with impurities. As more and more impurities accumulate on the mesh 608 and its permeability becomes worse and worse, the long-handled pressure sensor 614 senses the increase in pressure inside the blanking slit 303. The long-handled pressure sensor 614 then sends the monitored pressure value to the controller 309. When the pressure value reaches the preset value inside the controller 309, the replacement motor 605 rotates half a circle with the replacement cylinder 603 via the adapter short shaft 604. Then, the replacement cylinder 603 drives the first stainless steel mesh 608 and the second stainless steel mesh 609 to swap up and down. At this time, the second stainless steel mesh 609 enters the working position, and the first stainless steel mesh 608 enters the backwashing position.

[0081] When the first stainless steel woven mesh 608 and the second stainless steel woven mesh 609 are swapped up and down, the fixed edge strip 801, the tension spring 802, the bearing plate 803, and the elastic plug 804 rotate synchronously with the replacement cylinder 603, and then the two bearing plates 803 slide on the surfaces of the guide tube 805 and the cutting plane 806 respectively, and then the bearing plate 803 that slides from the surface of the cutting plane 806 to the surface of the guide tube 805 moves away radially, and then this bearing plate 803 blocks the corresponding recoil hole 708 with the elastic plug 804; the bearing plate 803 that slides from the surface of the guide tube 805 to the surface of the cutting plane 806 moves closer radially, and then this bearing plate 803 pulls the elastic plug 804 out of the recoil hole 708, so that an annular gap is formed between the elastic plug 804 and the recoil hole 708, thereby ensuring that the recoil hole 708 corresponding to the working position is in a blocked state, and the recoil hole 708 corresponding to the flushing position is in an open state;

[0082] Afterwards, the controller 309 controls the cleaning water to enter the water holding chamber 706 through the outlet water pipe 705 and the guide pipe 805, and then the flushing water is sprayed toward the first stainless steel woven mesh 608 through the annular gap between the elastic plug 804 and the backwash hole 708 to achieve backwashing. Then the flushing water passes through the second stainless steel woven mesh 609 and flows downward with impurities. After that, the flushing water passes through the leakage slit 602 into the collection chamber 902 and is discharged from the slag discharge pipe 903. When the flushing time reaches the preset value, the controller 309 controls the flow to be cut off.
