Description

Technical Field

[0001] This invention relates to the field of carpet production equipment technology, specifically to a high flame-retardant and wear-resistant nylon engineering carpet printing production device. Background Technology

[0002] Carpets are floor coverings made from natural fibers such as cotton, linen, wool, silk, and grass yarn, or chemically synthesized fibers, through hand or machine processes of weaving, tufting, or spinning. Carpets cover the floors of residences, hotels, conference rooms, entertainment venues, stadiums, exhibition halls, vehicles, ships, and airplanes, providing functions such as noise reduction, heat insulation, improved foot feel, and slip prevention. During carpet production, depending on the application scenario, printing is required on the carpet body to give it corresponding patterns, thereby enhancing its overall aesthetics. With the development of printing technology, digital inkjet printing devices are widely used; however, the printing effects of existing inkjet printing devices are still not ideal, with poor color fastness and incomplete printed patterns.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0004] The first objective of this invention is to address the above-mentioned shortcomings by providing a high flame-retardant and wear-resistant nylon engineering carpet printing production device that is simple in structure, has high production efficiency, and produces carpets with clear patterns that are not easy to fade.

[0005] The first solution adopted by the present invention to solve the technical problem is: a high flame-retardant and wear-resistant nylon engineering blanket printing production device, comprising a blanket feeding mechanism, an inkjet mechanism, a high-temperature color fixing mechanism, and a washing mechanism arranged sequentially along the feeding sequence. The blanket feeding mechanism includes an unfolding component, an impregnation component, and a pressing component arranged sequentially along the feeding sequence. The inkjet mechanism includes a conveying component, a printhead component, and a moving component. The conveying component includes a conveying frame, a front conveying roller group located in front of the conveying frame, and a rear conveying roller group located behind the conveying frame. The moving component is located on the upper side of the conveying frame. The printhead component is mounted on the moving component and is driven by the moving component to move and print patterns on the base blanket.

[0006] Furthermore, since the base blanket is rolled up before printing, in order to fully unfold the rolled base blanket and prevent it from warping and affecting the printing effect, the unfolding assembly includes a spool for holding the base blanket roll, a loosening roller, a loosening motor for driving the loosening roller to rotate, a conveyor roller group, an unfolding frame, and several unfolding rollers. The loosening roller is located next to the spool so that it can roll and contact the base blanket roll to loosen it. The conveyor roller group has two sets, which are respectively located on the front and rear sides of the unfolding frame to lay the loosened base blanket flat on the unfolding frame. The several unfolding rollers are staggered vertically to form an S-shaped conveying path.

[0007] Furthermore, to ensure that the unwinding roller is always in contact with the base blanket roll and drives the base blanket roll to rotate and unwind, the unfolding assembly also includes an adaptive structure for driving the base blanket roll closer to the unwinding roller. The adaptive structure includes a stand, two connecting rods, and a tension spring. The unwinding roller is rotatably mounted on the stand, the upper ends of the two connecting rods are rotatably mounted on both sides of the stand, and the lower ends of the two connecting rods are connected to the left and right ends of the roll, respectively. The tension spring is located between the stand and the connecting rods to pull the connecting rods toward the stand, thereby driving the base blanket roll closer to the unwinding roller.

[0008] Furthermore, in order to treat the base blanket to ensure the colorfastness of the base blanket, the impregnation assembly includes an impregnation roller located behind the unfolding assembly, an impregnation tank containing the treatment liquid, and a first squeezing roller group located above the impregnation tank for squeezing out the moisture from the base blanket. The impregnation roller includes a roller shaft and a roller surface. The roller shaft is rotatably installed inside the impregnation tank, and the roller surface is arranged around the outer periphery of the roller shaft. The roller surface and the roller shaft are connected by a bracket. The roller surface is provided with several through holes to ensure that the base blanket is in full contact with the treatment liquid.

[0009] Furthermore, in order to flatten the printing surface of the substrate and prevent fuzzing that could affect the printing effect, the heat pressing assembly is located behind the impregnation assembly. The heat pressing assembly includes a heat pressing roller, a heat pressing plate, and a high-temperature straightening roller assembly. The heat pressing plate has an arc-shaped structure, and a heating device is connected to one end of both the heat pressing plate and the high-temperature straightening roller assembly. The heat pressing roller is located below the heat pressing plate, and the inner diameter of the heat pressing plate is adapted to the outer diameter of the heat pressing roller so that the heat pressing roller can press the printing surface of the substrate onto the heat pressing plate for heat pressing treatment. The high-temperature straightening roller assembly is located behind the heat pressing roller so that the substrate deformed by the heat pressing plate can be reversed and straightened.

[0010] Furthermore, in order to clamp the two sides of the base blanket and tighten it for printing, the inkjet mechanism also includes a tensioning assembly for clamping the two sides of the base blanket, the tensioning assembly including two clamps and an adjusting member for adjusting the distance between the two clamps to accommodate base blankets of different widths.

[0011] Furthermore, to ensure that the tensioning assembly can adapt to base blankets of different widths, the clamp includes a base, an upper clamp and a lower clamp rotatably mounted on the base, and a clamping cylinder for driving the upper and lower clamps to clamp the base blanket. The conveyor frame has sliding grooves on both sides, and sliders are provided on the sliding grooves. One end of the adjusting member is rotatably mounted on the slider, and the other end of the adjusting member is rotatably connected to the base. The slider has an arc-shaped groove, and the adjusting member has bolts and nuts for locking the adjusting member on the slider. The bolts pass through the arc-shaped groove.

[0012] Furthermore, in order to perform high-temperature color-fixing treatment on the base blanket, the high-temperature color-fixing mechanism includes a steam chamber, a steam generator, and a guide assembly for guiding steam to the base blanket. The guide assembly has two sets, which are respectively located on the upper and lower sides of the steam chamber. The guide assembly includes several blowers and a mounting frame. The mounting frame is fixedly installed inside the steam chamber. A steam main pipe is provided inside the mounting frame. One end of the steam main pipe is connected to the steam generator. The blowers are slidably installed on the mounting frame, and each blower is connected to the steam main pipe through a hose.

[0013] Furthermore, in order to wash away the loose dye on the base blanket, the washing mechanism includes a washing tank, which is equipped with a microwave oscillator, and a second set of squeezing rollers for squeezing out the moisture from the base blanket is provided above the washing tank.

[0014] The second objective of this invention is to address the above-mentioned shortcomings by providing a production process for a high flame-retardant and wear-resistant nylon engineering blanket printing production device that allows for adjustment of light transmittance according to weather conditions.

[0015] The second solution adopted by the present invention to solve the technical problem is: a production process for a high flame-retardant and wear-resistant nylon engineering blanket printing production device, comprising the following steps:

[0016] (1) Place the base blanket roll on the roll shaft. The unwinding motor drives the unwinding roller to rotate. Under the combined action of its own weight and the tension spring force, the base blanket roll approaches the unwinding roller and is unwound as the unwinding roller rotates.

[0017] (2) After unwinding, the base blanket is laid flat on the unfolding frame under the drive of the conveyor roller group, and then conveyed to the unfolding roller. The rolled base blanket is fully unfolded to avoid the base blanket warping and affecting the printing effect.

[0018] (3) After the unfolded base blanket is treated with the treatment liquid, it is squeezed dry by the first extrusion roller group and then enters between the heat pressing roller and the heat pressing plate. The heat pressing roller presses the printing surface of the base blanket onto the heat pressing plate. While drying the base blanket, the high temperature heat pressing treatment flattens the printing surface of the base blanket for printing.

[0019] (4) The front conveyor roller group and the rear conveyor roller group convey the base blanket to be laid flat on the conveyor frame. Two clamps clamp the two sides of the base blanket to tighten the base blanket and prevent it from shifting. The moving component drives the nozzle assembly to move back and forth to print patterns on the base blanket.

[0020] (5) After the pattern printing is completed, the base blanket is put into the steam box. The blowers on the upper and lower sides of the steam box blow steam onto the base blanket to ensure that the base blanket is in full contact with the high temperature steam and heat-fixed.

[0021] (6) After the heat-fixed base blanket is put into the washing tank for washing, the microwave oscillator in the washing tank generates vibration to fully wash away the floating color on the base blanket. After the washing is completed, the base blanket is squeezed dry by the second extrusion roller group and output, and then rolled and packaged.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] (1) In order to facilitate transportation and storage, the base blanket is in a roll state. Before printing, in order to fully unfold the base blanket and avoid the base blanket curling and affecting the printing effect, the present invention is equipped with an unfolding component. The unwinding motor drives the unwinding roller to rotate, which drives the base blanket roll to automatically unwind. The unfolding frame can spread out the base blanket and flatten it from a curled state. At the same time, it is also convenient for workers to check the base blanket in time. Then, the base blanket is conveyed by several unfolding rollers in the forward and reverse directions to ensure that it is fully unfolded for printing.

[0024] (2) Before printing, the base carpet is soaked in the treatment liquid to improve the color fixity of the carpet. After soaking, the treatment liquid is squeezed dry by the first extrusion roller group. In addition, before printing, the base carpet needs to pass through the heat pressing component. The heat pressing component can flatten the rough surface of the base carpet to ensure the printing effect, and can also dry the base carpet that is wet due to soaking in the treatment liquid. In addition, the present invention uses a heat pressing plate with an arc structure, which can keep the base carpet in high temperature contact for a certain period of time, thereby ensuring the drying and heat pressing effect.

[0025] (3) The present invention uses a tensioning component to tighten both sides of the base carpet to avoid the base carpet from loosening and affecting the printing effect, thereby ensuring that the inkjet mechanism prints a clear and complete pattern on the base carpet. In addition, the tensioning component can adapt to carpets of different widths and has a wide range of applications. Attached Figure Description

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0037] Example 1: As Figure 1-8 As shown, this embodiment provides a high flame-retardant and wear-resistant nylon engineering blanket printing production device, including a blanket feeding mechanism, an inkjet mechanism, a high-temperature color fixing mechanism, and a washing mechanism arranged sequentially along the feeding sequence. The blanket feeding mechanism includes an unfolding component, an impregnation component, and a pressing component arranged sequentially along the feeding sequence.

The moving component 25 is located on the upper side of the conveyor frame 1, and the printhead component 24 is mounted on the moving component 25 and driven by the moving component 25 to move and print patterns on the base blanket 9.

[0038] In this embodiment, since the base blanket 9 is in a rolled state before printing, in order to fully unfold the rolled base blanket 9 and prevent the base blanket 9 from warping and affecting the printing effect, the unfolding assembly includes a roll 4 for placing the base blanket roll, a loosening roller 5, a loosening motor for driving the loosening roller 5 to rotate, a conveyor roller group 6, an unfolding frame 7, and several unfolding rollers 8. The loosening roller 5 is located beside the roll 4 so as to roll and contact the base blanket roll to loosen it. The conveyor roller group 6 has two groups, which are respectively located on the front and rear sides of the unfolding frame 7 to lay the loosened base blanket 9 flat on the unfolding frame 7. Several unfolding rollers 8 are staggered vertically to form an S-shaped conveying path.

[0039] In this embodiment, to ensure that the unwinding roller 5 is always in contact with the base blanket roll and drives the base blanket roll to rotate and unwind, the unfolding assembly also includes an adaptive structure for driving the base blanket roll closer to the unwinding roller 5. The adaptive structure includes a frame 10, two connecting rods 11 and a tension spring 12. The unwinding roller 5 is rotatably mounted on the frame 10. The upper ends of the two connecting rods 11 are rotatably mounted on both sides of the frame 10, and the lower ends of the two connecting rods 11 are connected to the left and right ends of the roll 4, respectively. The tension spring 12 is located between the frame 10 and the connecting rods 11 to pull the connecting rods 11 toward the frame 10, thereby driving the base blanket roll closer to the unwinding roller 5.

[0040] In this embodiment, in order to process the base blanket 9 to ensure the colorfastness of the base blanket 9, the impregnation assembly includes an impregnation roller 13 located behind the unfolding assembly, an impregnation tank 14 containing the treatment liquid, and a first squeezing roller group 15 located above the impregnation tank 14 for squeezing out the moisture from the base blanket 9. The impregnation roller 13 includes a roller shaft and a roller surface. The roller shaft is rotatably installed inside the impregnation tank 14. The roller surface is arranged around the outer periphery of the roller shaft. The roller surface and the roller shaft are connected by a bracket. The roller surface is provided with several through holes to ensure that the base blanket 9 is in full contact with the treatment liquid.

[0041] In this embodiment, in order to flatten the printing surface of the base blanket 9 and prevent the printing surface of the base blanket 9 from becoming fuzzy and affecting the printing effect, the heat pressing assembly is located behind the impregnation assembly. The heat pressing assembly includes a heat pressing roller 16, a heat pressing plate 17, and a high-temperature straightening roller group 18. The heat pressing plate 17 has an arc-shaped structure. One end of the heat pressing plate 17 and the high-temperature straightening roller group 18 are both connected to a heating device. The heat pressing roller 16 is located below the heat pressing plate 17. The inner diameter of the heat pressing plate 17 is adapted to the outer diameter of the heat pressing roller 16 so that the heat pressing roller 16 presses the printing surface of the base blanket 9 onto the heat pressing plate 17 for heat pressing treatment. The high-temperature straightening roller group is located behind the heat pressing roller 16 so as to reverse and straighten the base blanket 9 that has been deformed by the heat pressing plate 17.

[0042] In this embodiment, in order to clamp the two sides of the base blanket 9 and tighten the base blanket 9 for printing, the inkjet mechanism also includes a tensioning assembly for clamping the two sides of the base blanket 9, the tensioning assembly including two clips 28 and an adjusting member 29 for adjusting the distance between the two clips 28 to accommodate base blankets 9 of different widths.

[0043] In this embodiment, to ensure that the tensioning assembly can adapt to base blankets 9 of different widths, the clamp 28 includes a base, an upper clamp and a lower clamp rotatably mounted on the base, and a clamping cylinder for driving the upper clamp and the lower clamp to clamp the base blanket 9. The two sides of the conveying frame are respectively provided with sliding grooves 33, and sliding blocks 32 are provided on the sliding grooves 33. One end of the adjusting member 29 is rotatably mounted on the sliding block 32, and the other end of the adjusting member 29 is rotatably connected to the base. The sliding block 32 is provided with an arc-shaped groove 31. The adjusting member 29 is provided with a bolt 30 and a nut for locking the adjusting member 29 on the sliding block 32. The bolt 30 passes through the arc-shaped groove 31.

[0044] In this embodiment, in order to perform high-temperature color-fixing treatment on the base blanket 9, the high-temperature color-fixing mechanism includes a steam chamber 19, a steam generating device, and a guide assembly for guiding steam to the base blanket 9. The guide assembly has two sets, which are respectively located on the upper and lower sides of the steam chamber 19. The guide assembly includes several blowers 27 and a mounting frame 26. The mounting frame 26 is fixedly installed inside the steam chamber 19. A steam main pipe is provided inside the mounting frame 26. One end of the steam main pipe is connected to the steam generating device. The blowers 27 are slidably installed on the mounting frame 26, and each blower 27 is connected to the steam main pipe through a hose.

[0045] In this embodiment, in order to wash away the loose dye on the base blanket 9, the washing mechanism includes a washing tank 20, which is equipped with a microwave oscillator. Above the washing tank 20, there is a second squeezing roller group 21 for squeezing out the moisture from the base blanket 9.

[0046] Example 2: This example provides a production process for a high flame-retardant and wear-resistant nylon engineering blanket printing production device, including the following steps:

[0047] (1) Place the base blanket roll on the roll 4. The unwinding motor drives the unwinding roller 5 to rotate. Under the combined force of its own weight and the elastic force of the tension spring 12, the base blanket roll approaches the unwinding roller 5 and is unwound as the unwinding roller 5 rotates.

[0048] (2) The unrolled base blanket 9 is laid flat on the unfolding frame 7 under the drive of the conveying roller group 6, and then conveyed to the unfolding roller 8. The rolled base blanket 9 is fully unfolded to avoid the base blanket 9 warping and affecting the printing effect.

[0049] (3) After the unfolded base blanket 9 is treated with the treatment liquid, it is squeezed dry by the first extrusion roller group 15 and enters between the heat pressing roller 16 and the heat pressing plate 17. The heat pressing roller 16 presses the printing surface of the base blanket 9 onto the heat pressing plate 17. While drying the base blanket 9, the high temperature heat pressing treatment flattens the printing surface of the base blanket 9 so that it can be printed.

[0050] (4) The front conveyor roller group 62 and the rear conveyor roller group 63 convey the base blanket 9 to be laid flat on the conveyor frame 1. Two clamps 28 clamp the two sides of the base blanket 9, tighten the base blanket 9, and prevent the base blanket 9 from shifting. The moving component 25 drives the nozzle component 24 to move back and forth to print patterns on the base blanket 9.

[0051] (5) After the pattern printing is completed, the base blanket 9 enters the steam box 19. The blowers 27 on the upper and lower sides of the steam box 19 blow steam onto the base blanket 9 to ensure that the base blanket 9 is in full contact with the high temperature steam and heat-fixed.

[0052] (6) After the heat-fixed base blanket 9 is put into the washing tank 20 for washing, the microwave oscillator in the washing tank 20 generates vibration to fully wash away the floating color on the base blanket 9. After the washing is completed, the base blanket 9 is squeezed dry by the second extrusion roller group 21 and output, and then rolled and packaged.

[0053] This invention includes a carpet loading mechanism, an inkjet mechanism, a high-temperature color-fixing mechanism, and a washing mechanism. For ease of transportation and storage, the base carpet 9 is always in a rolled state. The unfolding component of the carpet loading mechanism can fully unfold the base carpet 9 before printing, preventing the carpet from curling and affecting the printing effect. The unwinding motor drives the unwinding roller 5 to rotate, automatically unwinding the base carpet roll. The unfolding frame 7 can spread the base carpet 9 out, flattening it from a curled state. This also facilitates timely inspection of the base carpet 9 by workers. Then, the base carpet 9 is conveyed forward and backward by several unfolding rollers 8 to ensure it is fully unfolded for printing. Furthermore, before printing, the base carpet 9 is soaked in a treatment solution to improve the carpet's color fixation. After soaking, the treatment solution is expelled by the first extrusion roller group 15. After the base carpet 9 is soaked in the treatment solution, it needs to pass through a heat pressing component before printing. The heat pressing component can flatten the rough surface of the base carpet 9 to ensure the printing effect, and it can also dry the base carpet 9 that has been wetted by the treatment solution. In addition, the present invention uses an arc-shaped heat pressing plate 17, which can maintain the base carpet 9 in high-temperature contact for a certain period of time, thereby ensuring the drying and flattening effect. In addition, the tensioning component tightens the two sides of the base carpet 9 to prevent the base carpet 9 from loosening and affecting the printing effect, thereby ensuring that the inkjet mechanism prints a clear and complete pattern on the base carpet 9. Furthermore, the tensioning component can adapt to carpets of different widths and has a wide range of applications. After printing, the base carpet 9 is subjected to high-temperature treatment, which can improve the color fixation and prevent the carpet from fading.

It should be understood that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
