Description

Technical Field

[0001] This invention relates to the field of fabric processing and production technology, and in particular to an environmentally friendly composite nonwoven fabric production line. Background Technology

[0002] Fabric production and processing requires multiple steps to form. First, fabrics are divided into natural fibers or synthetic fibers. If it is a natural fiber, it needs to be harvested, peeled, and washed. If it is a synthetic fiber, it is made by mixing raw materials and then spinning and setting the yarn. After the fibers are formed, they are processed by twisting and combining to form yarn. Then, they are processed and wound onto the winding rollers, woven, dyed with the required colors, and then set and dried. Finally, the formed fabric is sewn or glued to the desired product. Non-woven fabric is also a type of synthetic fiber.

[0003] When nonwoven fabric is processed into cloth after being spun into yarn, if the fabric needs to have a variety of colors due to the application scenario, dyeing after forming is relatively simple, which is inconvenient when rich color matching is required. Therefore, there is another process, which is spray dyeing, which makes it convenient to dye at different stages, then dry and roll up uniformly. After the spray-dyed yarn is completed, it continues to be rolled up and is conveyed into the drying step during the winding process. After setting, it is rolled up. However, during the parallel conveying process, adjacent yarns may stick together due to the large amount of dye in some places and the shaking. This causes adjacent yarns to stick together through the dye. If they are brought into the drying step before drying and setting, the yarns will stick together and be set, which will make subsequent winding inconvenient. At the same time, because spray dyeing is different from existing water dyeing such as dip dyeing, it is drier and has stronger adhesion, which requires forced separation and may even damage the yarn and dye. Therefore, another solution is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an environmentally friendly composite nonwoven fabric production line to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly composite nonwoven fabric production line, including a spray dyeing device. The rear end of the spray dyeing device is provided with a main body, a nozzle, an air pump, and a dye liquor supply component. The nozzle is connected to the dye liquor supply component. The front end of the main body is provided with a plurality of yarn winding kits. The front end of the spray dyeing device is provided with a yarn guide component for accommodating a plurality of yarns passing through. The rear end of the spray dyeing device is provided with a drying device for drying. A yarn separation component is provided between the drying device and the spray dyeing device. The rear end of the drying device is provided with a yarn winding kit.

[0006] The separation assembly includes a bracket connected to the dyeing equipment. The bracket is provided with a rotating roller 1 and a rotating roller 2 that guide and tension the yarn. The bracket is provided with a support roller. A connecting rod 1 is rotatably connected to the support roller. The connecting rod 1 is provided with a plug for embedding between several yarns. The rotating roller 2 is provided with a drive component that drives the plug to reciprocate.

[0007] The driving component includes a protrusion on the rotating roller, and the protrusion rotates around the center of the rotating roller. The connecting rod is connected to the connecting rod 1, and one end of the connecting rod 2 extends to the rotating roller 2. The connecting rod 2 is provided with a guide groove to accommodate the movement of the protrusion, and the protrusion pushes the connecting rod 2 along the inner wall of the guide groove to drive the connecting rod 1 to swing. The drying device and the kit 2 are provided with a yarn guide 2 that has the same function as the yarn guide 1.

[0008] Preferably, the insert reciprocates and oscillates, embedding itself into the gap between the yarns and then moves laterally. The insert and the first connecting rod are slidably connected by a support rod. The first connecting rod is provided with a sleeve to accommodate the embedded support rod, and a spring is provided between the support rod and the sleeve to push the support rod and the insert to move left and right. The support roller is provided with a push block to push the support rod to move, and the support rod is provided with an abutting part to accommodate the push block to pass through and abut against the push block. The abutting part and the abutting surface of the push block are arc-shaped.

[0009] Preferably, the separation components are symmetrically arranged, and the plugs on the two separation components are provided with plug-in insertion cleaning parts at the points where the plugs are close to each other, and the push blocks on the symmetrically arranged separation components are arranged in opposite left and right positions.

[0010] Preferably, the cleaning component includes a water storage box, the upper surface of which is provided with a sponge strip that is in contact with water and absorbs water, and the sponge strip accommodates the direct insertion of the plug. The support rod is rotatably connected to the plug, and a gear is provided at the rotatable connection between the plug and the support rod. A rack is provided on the water storage box along the swing path of the plug, which abuts against the gear and pushes the gear to rotate.

[0011] Preferably, the first and second rotating rollers are provided with abutting wiping parts, and a spring is provided between the plug and the support rod to push the plug back to its original position.

[0012] Preferably, the rotating roller two is rotatably connected to a pull rod one at its center, and the pull rod one is rotatably connected to a pull rod two at a position away from the center of the rotating roller two. The end of the pull rod two away from the pull rod one extends upward. An abutment block one is slidably connected to the bracket. The abutment block one is rotatably connected to the pull rod two. The bracket is provided with a groove that guides and restricts the up-and-down movement of the abutment block one. An extrusion block for extruding yarn is connected to the abutment block one.

[0013] Preferably, the extrusion blocks are provided in two pairs of four, with two extrusion blocks in each pair respectively positioned before and after the insert. The support is provided with a second abutment block opposite to the extrusion blocks at the lower end of the yarn.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] Firstly, after improvement, the dyed yarn is wound up and passes through the separation component. As the rotating roller 2 rotates continuously, it drives the protrusion to rotate synchronously. The protrusion pushes the connecting rod 2 along the inner wall of the guide groove. The connecting rod 2 is connected to the support roller along the connection point with the connecting rod 1. This rotation drives the plug and the support rod to swing, allowing the plug to pass through several yarns upwards. The plug and the yarn guide are equally spaced, facilitating the separation of the yarn. After passing through the yarn, the yarn moves along the gaps between the plugs. The force of the plug blocking and the pulling force can separate the adjacent bonded yarns. This design avoids the bonded yarns from being set during drying and setting, and also avoids the pigment from becoming loose after the dyeing and setting of the bonded yarns after separation at the yarn guide 2, thus avoiding uneven dyeing of the yarn. Secondly, separating the yarns before setting ensures that the dyeing of the yarn is not damaged, thus ensuring dyeing uniformity before drying and setting. Because separation after dye curing can easily cause other parts of the yarn to separate and tear together, or cause the bonded parts to separate, resulting in one yarn having more dye and the other having no dye. Furthermore, because sprayed dyes have strong adhesion, the plug separates the bonded parts while the unbonded parts move stably. This also reduces the occurrence of excessive dye being swept off by the plug. This device can avoid this problem by easily separating the yarn before it is set, and by using the adsorption and adhesion between the dye and the yarn. At the same time, the plug and other components are made of materials that reduce dye adsorption, so that the dye adsorption will not be damaged by simple pushing and touching, thus ensuring the uniformity of the dye on the yarn.

[0016] Secondly, when the plug is oscillating, it moves the support rod synchronously. The abutment of the support rod moves to the push block, and since the push block cannot move, it pushes the abutment to slide the support rod along the sleeve. This causes the plug embedded between the yarns to move laterally, compressing the spring. As a result, the force of the lateral movement between the embedded yarns makes the bonded yarns separate better. Furthermore, with the setting of two separation components, the yarn passes through the rear separation component. Since the rear support rod, abutment, and push block are set opposite to the front, when the rear plug swings upward, the direction of the plug's lateral movement is opposite to that of the front. After the plug resets, it causes the support rod to reset and disengage from the push block, pushing the spring and causing the support rod and plug to reset. This achieves the effect of left and right oscillation. Under the opposite force of the movement directions of the two plugs, the adjacent bonded yarns are more easily separated. By limiting the range of movement, the situation of unbonded yarns being over-pushed is avoided, thus better ensuring the uniformity of the dye.

[0017] Thirdly, when the rotating roller 2 rotates, it directly drives the pull rod 1 to rotate, and the pull rod 1 pulls the pull rod 2 downwards and rotates. At the same time, because the other end of the pull rod 2 is rotatably connected to the abutment block 1 and the abutment block 1 can only move, when the pull rod 2 moves downwards and rotates, it will pull the abutment block 1 to move downwards and approach the yarn. Then, the abutment block 1 will drive the connected extrusion block downwards, so that the extrusion block and the abutment block 2 form a clamping force to restrict the up and down movement and swing of the yarn. The yarn is tightened by the restriction of the abutment block 2 and the extrusion block, so that the yarn is tightened and moved better when the plug is inserted. Thus, after the above settings, it is ensured that the yarn can be clearly separated after dyeing, and then it can be shaped and dried to ensure that each yarn is dyed evenly and will not cause the yarn to be shaped after bonding. In addition, the contact area between the extrusion part and the abutment block 2 and the yarn can be freely reduced as needed. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. In this description, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] An environmentally friendly composite nonwoven fabric production line, such as Figures 1-7As shown, the device includes a spray dyeing system. At the rear end of the spray dyeing system are a main body 1, nozzles 2, an air pump 3, and a dye liquor supply assembly 4. Nozzles 2 are connected to the dye liquor supply assembly 4. At the front end of the main body 1 are several yarn winding kits 5. At the front end of the spray dyeing system is a yarn guide 6 for accommodating several yarns. At the rear end of the spray dyeing system is a drying device 7 for drying. A yarn separation assembly is provided between the drying device 7 and the spray dyeing system. At the rear end of the drying device 7 is a yarn winding kit 8. The yarn separation assembly includes a bracket 9 connected to the spray dyeing system. The bracket 9 has a rotating roller 10 and a rotating roller 11 that guide and tension the yarn. A support roller is also provided on the bracket 9. 12. A connecting rod 13 is rotatably connected to the support roller 12. The connecting rod 13 is provided with a plug 14 for embedding between several yarns. The rotating roller 2 11 is provided with a driving component for reciprocating the plug 14. The driving component includes a protrusion 15 provided on the rotating roller, and the protrusion 15 rotates along the center of the rotating roller 2 11. A connecting rod 2 16 is connected to the connecting rod 13, and one end of the connecting rod 2 16 extends to the rotating roller 2 11. The connecting rod 2 16 is provided with a guide groove 17 for accommodating the movement of the protrusion 15. The protrusion 15 pushes the connecting rod 2 16 along the inner wall of the guide groove 17, causing the connecting rod 13 to swing. A yarn guide 2 18 with the same function as the yarn guide 1 6 is provided between the drying device 7 and the kit 2 8.

[0028] Using this device, the yarn is pulled out after passing through the dyeing equipment and then passes through rotating roller 10 and rotating roller 21. Rotating roller 10 and rotating roller 21 tension the yarn and change its movement path. Next, as it passes through rotating roller 21, it drives the protrusion 15 to rotate synchronously. When the protrusion 15 rotates, it pushes the connecting rod 216 along the inner wall of the guide groove 17. Since the other end of the connecting rod 216 is connected to the connecting rod 13 and rotatably connected to the support roller 12, the connecting rod 13... Link 13 drives connecting rod 16 to rotate and oscillate along support roller 12. The oscillation of connecting rod 13 synchronizes the connected support rod 19, sleeve 20, and insert 14, causing insert 14 to rotate upwards and embed into the gaps between adjacent yarns. Since insert 14 and yarn guide 6 are spaced evenly, the yarns move along insert 14 after passing through the gaps and separate, moving to the next process. This separation prevents the yarns from being fixed after dye adhesion, which would disrupt the uniformity of dye adhesion after drying and setting.

[0029] After the insert 14 reciprocates and embeds itself into the gap between the yarns, it moves laterally. The insert 14 and the connecting rod 13 are slidably connected by the support rod 19. The connecting rod 13 is provided with a sleeve 20 to accommodate the insertion of the support rod 19, and a spring 21 is provided between the support rod 19 and the sleeve 20 to push the support rod 19 and the insert 14 to move left and right. The support roller 12 is provided with a push block 22 to push the support rod 19 to move, and the support rod 19 is provided with an abutment part 23 to accommodate the push block 22 and to abut against the push block 22. The abutment part 23 and the abutment surface of the push block 22 are arc-shaped. The separation components are symmetrically arranged, and the inserts 14 on the two separation components are provided with a place to accommodate the insert 14 when they are close to each other. The insert cleaning component is embedded, and the push blocks 22 on the symmetrically arranged separation components are positioned in opposite left and right directions. After the insert 14 rotates upwards to embed into the gap between the yarns, the abutment part 23 on the support rod 19 moves synchronously, while the support roller 12 does not rotate synchronously. The abutment part 23 rotates and engages with the push block 22. Because the support roller 12 is too heavy, it will not be driven to rotate synchronously. When it cannot move, the pushing force of the push block 22 and the up-and-down pushing force of the support roller 12 cause the abutment part 23 to be pushed by the push block 22, which in turn causes the support rod 19 to compress the spring 21. This pushes the separated yarns towards the spring 21, causing the yarns to separate. The yarn is more clearly defined. Secondly, the separation components are symmetrically arranged. After the front insert 14 rotates, the rear insert 14 of the separation component will also be driven by the rotating roller to synchronously embed into the yarn. Because the contact part 23 is opposite to the front support rod 19, when the front insert 14 moves laterally between the yarns after rotation, the rear insert 14 moves in the opposite direction. Thus, the lateral movement directions of the front and rear inserts 14 are opposite, making the yarn taut and moving left and right, making the adjacent yarns more distinct and preventing them from sticking together. Compared with the prior art of separating after shaping, this application can reduce the damage to the uniformity of yarn dyeing and ensure the uniformity of yarn dyeing by separating in advance. Secondly, compared to directly setting a yarn guide in front of the drying device 7 to separate the yarn, the swinging plug 14 can reduce the situation of the dye being scraped off the yarn. Because if a yarn guide is fixed to accommodate the yarn, the yarn will easily stick and the unformed dye will be scraped off. However, by inserting the swinging plug 14 into the yarn and immediately moving it down, the contact time is reduced and the adhesion with the dye is reduced. This also reduces the dye being scraped off and improves the uniformity of spraying. In addition, because spraying dyeing is different from water dyeing, the dye is drier and therefore has a greater adhesion after it is attached to the yarn. The swinging plug 14 can reduce the situation of the dye being scraped off or swept off by a short contact.

[0030] The cleaning component includes a water storage box 24. The upper surface of the water storage box 24 is provided with a water-absorbing sponge strip 25, which accommodates the direct insertion of the plug 14. A support rod 19 is rotatably connected to the plug 14. A gear 26 is provided at the rotatable connection between the plug 14 and the support rod 19. A rack 27 on the water storage box 24, located on the swing path of the plug 14, abuts against the gear 26 and drives the gear 26 to rotate. Wiping elements 28 abut against the rotating rollers 10 and 11. A spring 29 is provided between the plug 14 and the support rod 19 to push the plug 14 back to its original position. Furthermore, when the plug 14 returns to its original position, it approaches the water storage box 24 of the cleaning component, and the rack 27 engages with it. Insert the plug into the space between the support rod 19 and the plug 14, and abut against the gear 26 on the side of the plug 14. As the plug 14 continues to rotate, it moves along the rack 27. The rack 27 drives the gear 26 to rotate, and drives the plug 14 to rotate downward toward the water storage box 24. The top of the plug 14 is embedded in the sponge strip 25, and the dye is scraped off by the sponge strip 25. The sponge strip 25 absorbs water and moistens the yarn, so that the color of the yarn is different when it is sprayed in different positions. This avoids the situation where the dye on the plug 14 comes into contact with the yarn in different dye positions, which would cause the dye to mix and destroy the dye color. The insertion of the sponge strip 25 achieves the effect of automatic cleaning. Secondly, when the rotating roller 10 and the rotating roller 21 rotate continuously, they come into contact with the wiping component 28 to wipe away the dye, thus preventing the dye from mixing with dyes in different parts. In contrast, the fixed setting of the yarn guide separates and bonds the yarn, which makes it easier for the dye to mix with the yarn in different positions. The above setting better ensures the integrity of yarn dyeing. Secondly, some materials that reduce adhesion are coated on the contact object to reduce the adsorption of dye. Furthermore, the dye sprayed is also relatively dry, which also reduces adhesion.

[0031] A pull rod 30 is rotatably connected to the center of the rotating roller 11. A pull rod 31 is rotatably connected to the pull rod 30 away from the center of the rotating roller 11. The end of the pull rod 31 away from the pull rod 30 extends upward. An abutment block 32 is slidably connected to the bracket 9. The abutment block 32 is rotatably connected to the pull rod 31. The bracket 9 is provided with a groove 33 to guide and restrict the up and down movement of the abutment block 32. An extrusion block 34 for extruding yarn is connected to the abutment block 32. There are four extrusion blocks 34 in two pairs. The two extrusion blocks 34 in each pair are respectively located in front of and behind the insert 14. The bracket 9 is provided with an abutment block 35 at the lower end of the yarn, which is opposite to the extrusion block 34. Finally, the pull rod 30 is located at the center of the other side of the rotating roller 11 without the protrusion 15. When rotating, it drives the pull rod 30 to rotate. Rod 1 30 rotates synchronously, and rod 1 30 drives the rotatably connected rod 2 31 to pull it downwards. When rod 2 31 is driven downwards, it will simultaneously pull the rotatably connected abutment block 1 32 downwards. The abutment block 1 32 is restricted to moving only up and down by the slide groove 33. Under the pull of rod 1 30, rod 2 31 is pulled downwards and rotates along two rotation points. Thus, rod 2 31 moves up and down. When abutment block 1 32 is driven downwards, it will drive the extrusion block 34 to move downwards synchronously and approach abutment block 2 35. The force between abutment block 2 35 and the extrusion block tightens the yarn and facilitates the insertion of plug 14 to increase yarn stability and facilitate separation. This improves the stability of yarn separation. After entering the drying device 7, adjacent yarns can be clearly separated.

[0032] First, the yarns wound on several kits 5 are passed through the yarn guide 6 set at the front end of the spray dyeing equipment in sequence, and the dye liquid is atomized by the atomizer and sprayed onto the yarns by the nozzle 2. The dye adheres to the yarns, and then the yarns are conveyed out of the spray dyeing equipment to continue to the next process, extending through to the separation component.

[0033] Finally, after the yarn dyeing enters the separation component, the drive component drives the plug 14, which is inserted between several yarns to separate the bonded yarns. This separates the dye bonded between adjacent yarns, making each yarn distinct. The distinct yarns continue to move and are conveyed to the drying device 7, where hot air is blown to dry them. This ensures that the dye sprayed on the distinct yarns is dry, guaranteeing that the yarns are distinct after separation and that the dye between adjacent yarns will not bond together. Finally, the dried and shaped yarns pass through the second yarn guide 18 and are connected to the second kit 8 in sequence to wind up the dyed yarns.
