Description

Technical Field

[0001] This invention relates to the field of fabric production technology, specifically to a polyester fabric production apparatus and its usage method. Background Technology

[0002] In the textile industry, polyester fabrics are highly favored due to their excellent physical properties and wide range of applications. The production process of polyester fabrics involves several key steps, among which dyeing is an important step to improve the appearance quality and added value of polyester fabrics. In the polyester fabric production process, polyester yarns are usually dyed before being spun into fabric to ensure the color consistency of the subsequent polyester fabrics.

[0003] Currently, the mainstream dyeing method for polyester yarn is the immersion dyeing method, which involves immersing the rolled polyester yarn into a dyeing vat filled with dye liquor. The dye liquor then gradually penetrates from the outer layer to the inner layer of the polyester yarn to achieve full dyeing. However, due to the low hygroscopicity of polyester yarn and the relatively tight roll of polyester yarn, the penetration speed of the dye liquor is relatively slow, and the entire dyeing process takes a long time, which in turn affects the production efficiency of polyester fabrics.

[0004] Therefore, the present invention proposes a polyester fabric production apparatus and a method of using it to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a polyester fabric production apparatus and a method of use to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A polyester fabric production apparatus and method of use include a dyeing vat and a vat cover disposed on the dyeing vat. The dyeing vat is provided with a material cylinder for placing polyester yarn and a plurality of mounting parts evenly arranged around the circumference of the material cylinder. Each mounting part is provided with a plurality of slide seats that can slide up and down with equal pitch. Each slide seat is provided with a piercing tube. The piercing tube wall is provided with liquid outlet holes evenly distributed. The material cylinder wall is provided with passage grooves corresponding to the plurality of mounting parts. The plurality of mounting parts can move synchronously toward the material cylinder to the dyeing station, so that the piercing tube is inserted into the material cylinder. The production apparatus also includes a delivery assembly for delivering dye solution into each puncture tube.

[0007] In one alternative embodiment: the production apparatus further includes a drive assembly for synchronously moving multiple mounting components to the dyeing station and resetting them. The drive assembly includes a frame housed in the dyeing vat. The frame house includes strip-shaped magnetic components that correspond one-to-one with the mounting components and are evenly distributed around the circumference of the material cylinder. Each strip-shaped magnetic component is fitted with a slidable iron support seat. The mounting component is mounted on the corresponding iron support seat. An elastic reset component is provided between the iron support seat and the end of the strip-shaped magnetic component away from the material cylinder. A second electromagnet is provided at the end of the strip-shaped magnetic component near the passage groove.

[0008] In one alternative: the iron support is covered with a waterproof membrane.

[0009] In one alternative: each of the mounting components has multiple slides, with the uppermost slide having a magnet, the magnet having its magnetic poles divided into upper and lower halves; each pair of adjacent slides on the same mounting component has a linkage rope; and the cylinder head has a first electromagnet for attracting the magnet to drive the multiple slides to slide sequentially to an equidistant distance.

[0010] In one alternative embodiment: the infusion assembly includes a collection cylinder mounted on a cylinder head and a sealing piston disposed within the collection cylinder. The sealing piston has a column, and the end of the column away from the sealing piston sealably penetrates the lower side of the collection cylinder and has a driven disc. Infusion tubing corresponding to multiple mounting components is arranged on the bottom side of the collection cylinder. The infusion tubing is connected to all puncture tubes on the corresponding mounting component. Each mounting component has multiple slides, with the uppermost slide having a drive rod. Each drive rod... Each of the drive rods has a slot at its upper end that fits the side of the driven plate. When multiple mounting parts move close to the material cylinder to the dyeing station, and multiple slides are in their initial positions and the driven plate is in its lower set position, the slots on the drive rods engage with the side of the driven plate. The bottom of the collection cylinder is also provided with a suction hose for drawing out the dye solution. The suction hose is provided with a first one-way valve to allow the dye solution to enter the collection cylinder in one direction. Each delivery hose is provided with a second one-way valve to allow the dye solution to be discharged from the collection cylinder in one direction.

[0011] In one alternative: a counterweight is provided at the end of the suction hose away from the collection cylinder.

[0012] A method of using a polyester fabric production apparatus employing any one of the above technical solutions includes the following steps: S1: Place the polyester yarn spools to be dyed in the dyeing cylinder in an orderly manner, then close the vat lid and introduce an appropriate amount of dye liquor into the dyeing vat. S2: Multiple mounting components move synchronously towards the material cylinder to the dyeing station, allowing the piercing tube to penetrate the interior of the polyester yarn roll; S3: The multiple sliding blocks on each mounting piece slide in a cyclical manner, thereby driving the piercing tube to repeatedly open the polyester yarn roll to create gaps and reset. The dye liquor enters the interior of the polyester yarn roll through the gaps, and at the same time, the dye liquor is delivered to each piercing tube through the liquid delivery component and discharged through the liquid outlet hole, so as to achieve simultaneous internal and external dyeing.

[0013] Compared with the prior art, the beneficial effects of the embodiments of the present invention are as follows: The polyester yarn rolls to be dyed are placed in the dyeing cylinder in an orderly manner. Then, the cylinder cover is closed and an appropriate amount of dye liquor is introduced into the dyeing cylinder. Next, multiple mounting parts move synchronously towards the dyeing cylinder to the dyeing station, so that the piercing tubes are inserted into the cylinder, that is, pierced into the interior of the polyester yarn rolls. During the dyeing process, multiple sliding seats on each mounting part slide in a cyclical manner, thereby driving the piercing tubes to repeatedly open the polyester yarn rolls to create gaps and reset. The dye liquor enters the interior of the polyester yarn rolls through the gaps. At the same time, the dye liquor is delivered to each piercing tube through the liquid delivery component and discharged through the liquid outlet hole, realizing simultaneous internal and external dyeing, which greatly reduces the dyeing time of polyester yarn and thus helps to improve the production efficiency of polyester fabrics.

Detailed Implementation

[0023] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Please see Figures 1-3 A polyester fabric production device includes a dyeing vat 1 and a vat cover 13 disposed on the dyeing vat 1. The dyeing vat 1 is provided with a material cylinder 2 for placing polyester yarn and a plurality of mounting parts 3 are evenly arranged around the material cylinder 2. Each mounting part 3 is provided with a plurality of slide seats 9 that can slide up and down with equal pitch. Each slide seat 9 is provided with a piercing tube 4. The piercing tube 4 is provided with liquid outlet holes 10 evenly distributed on its tube wall. The material cylinder 2 is provided with passage grooves 5 corresponding to the plurality of mounting parts 3 on its tube wall. The plurality of mounting parts 3 can move synchronously toward the material cylinder 2 to the dyeing station, so that the piercing tube 4 is inserted into the material cylinder 2. The production apparatus also includes a delivery assembly 7 for delivering dye solution into each puncture tube 4.

[0025] It should be noted that the wall of the material cylinder 2 is a grid-like structure, allowing the dye liquor to penetrate into the cylinder for immersion dyeing.

[0026] The polyester yarn rolls to be dyed are placed in the drum 2 in an orderly manner. Then, the cylinder cover 13 is closed and an appropriate amount of dye liquor is introduced into the dyeing cylinder 1 (completely immersing the drum 2). Then, multiple mounting parts 3 move synchronously towards the drum 2 to the dyeing station, so that the piercing tube 4 is inserted into the drum 2, that is, pierced into the inside of the polyester yarn roll. During the dyeing process, multiple sliding seats 9 on each mounting part 3 slide in a cyclical variable pitch, thereby driving the piercing tube 4 to repeatedly open the polyester yarn roll to create gaps and reset. The dye liquor enters the inside of the polyester yarn roll through the gaps. At the same time, the dye liquor is delivered to each piercing tube 4 through the liquid delivery component 7 and discharged through the liquid outlet 10, realizing simultaneous internal and external dyeing, which greatly reduces the dyeing time of polyester yarn and thus helps to improve the production efficiency of polyester fabric. It needs to be further explained that when the polyester yarn roll is opened to create gaps, the dye liquor in the gaps will be squeezed during reset, thereby promoting the internal penetration of the dye liquor.

[0027] Please see Figure 2 and Figure 4 In one embodiment of the present invention, the production device further includes a drive assembly 8 for realizing the synchronous movement of multiple mounting parts 3 to the dyeing station and their resetting. The drive assembly 8 includes a frame 801 disposed in the dyeing vat 1. The frame 801 includes strip frame 80 magnet parts 11 that correspond one-to-one with the mounting parts 3 and are evenly distributed around the material cylinder 2. Each strip frame 80 magnet part 11 is fitted with a slidable iron support seat 802. The mounting parts 3 are disposed on the corresponding iron support seats 802. An elastic resetting part 803 is provided between the iron support seat 802 and the end of the strip frame 80 magnet part 11 away from the material cylinder 2 (the elastic resetting part 803 can be a spring rope, spring, etc. in the prior art, which is not limited in this embodiment). A second electromagnet 804 is provided at the end of the strip frame 80 magnet part 11 near the passage groove 5.

[0028] In this embodiment, when it is necessary to drive multiple mounting parts 3 to move synchronously to the dyeing station, all second electromagnets 804 are controlled to be turned on to attract the iron support 802. When it is necessary to make multiple mounting parts 3 reset synchronously, all second electromagnets 804 are turned off and demagnetized, and the iron support 802 is reset under the action of the elastic reset member 803.

[0029] Furthermore, in this embodiment, the iron support 802 is covered with a waterproof membrane, which serves to prevent the dye liquid from contacting the iron support 802, thereby preventing the iron support 802 from rusting.

[0030] Please see Figure 1 and Figure 5In one embodiment of the present invention, each of the multiple slides 9 on the mounting member 3 is provided with a magnet 11 on the uppermost slide 9. The magnet 11 is divided into upper and lower halves with magnetic poles. A linkage rope 12 is provided between each pair of adjacent slides 9 on the same mounting member 3. The cylinder head 13 is provided with a magnet 11 for attracting the magnet 11 so as to drive the multiple slides 9 to slide sequentially to the first electromagnet 6 with equal spacing.

[0031] In this embodiment, by alternately changing the direction of the current in the first electromagnet 6, the magnetic poles of the first electromagnet 6 facing the magnet 11 change cyclically. Under the principle of magnetic repulsion between like poles and attraction between unlike poles, when the magnetic poles of the first electromagnet 6 facing the magnet 11 are opposite to the magnetic poles of the magnet 11 facing the first electromagnet 6, the first electromagnet 6 magnetically attracts the magnet 11, thereby driving the uppermost slide 9 to move upward. Under the action of the linkage rope 12, the uppermost slide 9 moves upward, driving the slide 9 to move upward sequentially from top to bottom until two adjacent slides 9 are equidistant. At this time, the polyester yarn roll is opened to create a gap. When the magnetic poles of the first electromagnet 6 facing the magnet 11 are the same as the magnetic poles of the magnet 11 facing the first electromagnet 6, the multiple slides 9 move downward and reset under the action of their own weight, the weight of the polyester yarn, the weight of the piercing tube 4, and the repulsive force of the first electromagnet 6. This cycle is repeated, thereby realizing the repeated opening of the polyester yarn roll to create gaps and reset.

[0032] Furthermore, in this embodiment, the first electromagnet 6 is ring-shaped so that it fully covers all the magnets 11 when energized and magnetized.

[0033] Please refer to 1. Figure 2 and Figure 6In one embodiment of the present invention, the infusion assembly 7 includes a collection cylinder 701 disposed on a cylinder cover 13 and a sealing piston 706 disposed in the collection cylinder 701. A column 707 is provided on the sealing piston 706. One end of the column 707, away from the sealing piston 706, passes through the lower side of the collection cylinder 701 in a sealed manner and is provided with a driven disc 708. Infusion tubing 702, corresponding one-to-one with multiple mounting components 3, is arranged on the bottom side of the collection cylinder 701. The infusion tubing 702 communicates with all the puncture tubes 4 on the corresponding mounting component 3. A drive rod 703 is provided on the uppermost of the multiple slides 9 on each mounting component 3. The upper end of each drive rod 703 is provided with a drive rod 708 connected to the driven disc 708. When the mounting parts 3 move towards the dyeing station and the multiple sliding blocks 9 are in their initial positions and the driven plate 708 is in its lower set position (i.e., the sealing piston 706 is in contact with the bottom side of the collection cylinder 701), the slots 709 on the multiple drive rods 703 are engaged with the side of the driven plate 708. The bottom side of the collection cylinder 701 is also provided with a suction hose 704 for extracting dye liquor. The suction hose 704 is provided with a first one-way valve (not shown in the figure) to allow the dye liquor to enter the collection cylinder 701 in one direction. Each delivery hose 702 is provided with a second one-way valve (not shown in the figure) to allow the dye liquor to be discharged from the collection cylinder 701 in one direction.

[0034] It should be noted that the purpose of providing a second one-way valve on each of the aforementioned infusion tubing 702 is to prevent the dye solution from being drawn from inside the polyester yarn roll (the dye solution flows back through the outlet hole 10) when drawing the dye solution.

[0035] In this embodiment, when the uppermost slide 9 moves upward, it drives the driven plate 708 to move upward, thereby causing the sealing piston 706 to move upward and draw the dye liquor into the collection cylinder 701. This process involves opening the polyester yarn roll to create a gap. When the uppermost slide 9 moves downward to reset, it drives the driven plate 708 to move downward, thereby causing the sealing piston 706 to move downward and squeeze the drawn dye liquor to flow into each infusion hose 702, and then into each puncture tube 4 and discharged through the outlet hole 10. This process involves resetting the gap in the polyester yarn roll. During the resetting process, the discharged dye liquor, in conjunction with the gap resetting squeezing action, can effectively promote the internal penetration of the dye liquor, thereby improving the dyeing efficiency.

[0036] Furthermore, in this embodiment, a counterweight 705 is provided at the end of the suction hose 704 away from the collection cylinder 701. When the cylinder cover 13 is closed, the suction hose 704 is moved to be located outside the material cylinder 2. Under the action of the counterweight 705, the suction end of the suction hose 704 (the end away from the collection cylinder 701) is always immersed in the dye liquor, ensuring effective absorption of the dye liquor.

[0037] The present invention also provides a method of using a polyester fabric production apparatus employing any one of the above-described technical solutions, comprising the following steps: S1: Place the polyester yarn spools to be dyed in the dyeing cylinder 2 in an orderly manner, then close the cylinder lid 13 and introduce an appropriate amount of dye liquor into the dyeing cylinder 1. S2: Multiple mounting parts 3 move synchronously towards the material cylinder 2 to the dyeing station, so that the piercing tube 4 pierces into the interior of the polyester yarn roll; S3: The multiple sliding blocks 9 on each mounting part 3 slide in a cyclical variable pitch, thereby driving the piercing tube 4 to repeatedly open the polyester yarn roll to create gaps and reset. The dye liquor enters the interior of the polyester yarn roll through the gaps, and at the same time, the dye liquor is delivered to each piercing tube 4 through the liquid delivery component 7 and discharged through the liquid outlet hole 10, so as to achieve simultaneous internal and external dyeing.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
