Description

Technical Field

[0001] This utility model belongs to the field of textile pretreatment technology, and specifically relates to a pretreatment device for pure acrylic fiber textiles used in aircraft cabins. Background Technology

[0002] Acrylic fiber pure textiles are frequently used in aircraft cabin seat fabrics, curtains, carpets, and other parts. They have excellent properties such as being lightweight and soft, having good flame retardancy, strong abrasion resistance, good chemical resistance, and good dyeability. Their good flame retardant properties can effectively prevent the occurrence and spread of fire, and improve the safety of aircraft cabins.

[0003] During the spinning and weaving process, acrylic fibers produce short and loose fluff due to friction. This fluff adheres to the fabric surface and affects the smoothness. If the fluff is not treated, it may cause defects such as uneven dyeing, printing sizing or sizing problems during the printing and dyeing process. Therefore, singeing pretreatment is required.

[0004] Current methods for singeing pretreatment of acrylic fiber fabrics typically utilize singeing equipment to remove loose fibers. However, before singeing, a brush roller is usually used to comb the fabric. The brush roller uses mechanical friction to stand the fibers upright, increasing the contact area with the flame and reducing the likelihood of incomplete singeing. However, existing singeing equipment usually lacks a cleaning mechanism for the brush roller. During brushing, short fibers, yarn ends, and other impurities adhering to the fabric surface easily become entangled on the brush roller surface, forming a fiber accumulation layer. As the equipment runs continuously, the entangled yarn ends significantly reduce the brush roller's combing ability, leading to uneven brushing, reduced fiber combing effect, and ultimately quality problems such as incomplete singeing. This necessitates periodic manual shutdowns to clean the brush roller, which is time-consuming and labor-intensive. Utility Model Content

[0005] Existing singeing pretreatment methods for acrylic fiber pure textiles typically utilize singeing devices to remove loose fibers. However, before singeing, brush rollers are usually used to comb the fabric, using mechanical friction to stand the fibers upright and increase the contact area with the flame, thus reducing the likelihood of incomplete singeing. However, existing singeing devices often lack a cleaning mechanism for the brush rollers. During brushing, short fibers, yarn ends, and other impurities adhering to the textile surface easily become entangled on the brush roller surface, forming a fiber accumulation layer. As the equipment operates continuously, the entangled yarn ends significantly reduce the brush roller's combing ability, leading to uneven brushing, reduced fiber combing effect, and ultimately quality problems such as incomplete singeing. This necessitates periodic manual cleaning of the brush rollers, which is time-consuming and labor-intensive. This invention proposes a pretreatment device for acrylic fiber pure textiles used in aircraft cabins to overcome the aforementioned technical problems in existing related technologies.

[0033] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0034] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements 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 utility model.

[0035] Please see Figures 1-8 As shown, this utility model is a pretreatment device for acrylic fiber pure textile fabrics for aircraft cabins, including a first mounting frame 1, a second mounting frame 2, and a third mounting frame 3. A brushing mechanism 4 is rotatably mounted on the first mounting frame 1 and the second mounting frame 2. A driving mechanism 5 is provided on both the first mounting frame 1 and the second mounting frame 2. Acrylic textile fabric 6 passes through the brushing mechanism 4. A singeing mechanism 7 is provided on the third mounting frame 3. A cleaning mechanism 8 is provided on both the first mounting frame 1 and the second mounting frame 2. The brushing mechanism 4 and the cleaning mechanism 8 are connected by a transmission.

[0036] The brushing mechanism 4 is used to brush the upper and lower surfaces of the acrylic textile 6, thereby cleaning and combing the upper and lower surfaces of the acrylic textile 6.

[0037] The singeing mechanism 7 is used to singe the upper and lower surfaces of the acrylic textile 6, thereby removing impurities and short fibers from the upper and lower surfaces of the acrylic textile 6.

[0038] The drive mechanism 5 provides power for the operation of the brushing mechanism 4 and the cleaning mechanism 8, and the cleaning mechanism 8 is used to clean the brushing mechanism 4.

[0039] When in use, since the brushing mechanism 4, cleaning structure 8 and singeing mechanism 7 operate on the same principle, only their positions are changed. Their purpose is to perform surface treatment on the other side of the fabric. The following text takes the surface treatment of the lower side of the fabric as an example to explain the operating principle.

[0040] The acrylic textile 6 is passed from front to back through the brushing mechanism 4 located on the first mounting frame 1 and the second mounting frame 2. Then the drive mechanism 5 is started, and the drive mechanism 5 drives the brushing mechanism 4 to rotate. During the rotation of the brushing mechanism 4, the upper and lower outer surfaces of the acrylic textile 6 are brushed. At the same time, when the brushing mechanism 4 brushes the fluff on the fabric surface to stand up during the brushing process, the operation of the brushing mechanism 4 synchronously drives the cleaning mechanism 8 to work, so that the cleaning mechanism 8 further cleans the fluff that has been cleaned off the brushing mechanism 4.

[0041] As the fabric, after being processed by the brushing mechanism 4, continues to move forward under the action of the traction mechanism, it passes through the singeing mechanism 7. The singeing mechanism 7 singes one side of the fabric that has been processed by the brushing mechanism 4.

[0042] This invention uses a drive mechanism 5 to drive a brushing mechanism 4 to treat the surface pile of the fabric, making the pile stand up. It can also clean short fibers, yarn ends, dust, etc. on the surface of the acrylic textile 6, making it easier to singe the pile later. At the same time, the rotation of the brushing mechanism 4 causes the cleaning mechanism 8 to operate, so as to clean the pile on the brushing mechanism 4 and prevent the pile on the brushing mechanism 4 from accumulating and causing the yarn ends attached to the brushing mechanism 4 to affect the brushing effect on the acrylic textile 6.

[0043] The drive mechanism 5 drives the brushing mechanism 4 to operate, thereby brushing the upper and lower sides of the acrylic textile 6. At the same time, when the brushing mechanism 4 is operating, its rotation can drive the cleaning mechanism 8 to clean itself.

[0044] In one embodiment, the brushing mechanism 4 includes a lower roller brush 401. A support shaft 406 is rotatably sleeved on both the first mounting frame 1 and the second mounting frame 2. The lower roller brush 401 is fixedly sleeved on the outer surface of the support shaft 406 located on the first mounting frame 1. An upper roller brush 402 is fixedly sleeved on the outer surface of the support shaft 406 located on the second mounting frame 2. The positioning rollers 403 are rotatably connected to both the first mounting frame 1 and the second mounting frame 2. The limiting rollers 404 are rotatably connected to the first mounting frame 1 and the second mounting frame 2, respectively. The two limiting rollers 404 are adapted to the lower roller brush 401 and the upper roller brush 402, respectively. A transmission roller 405 is rotatably connected to the second mounting frame 2. The right end of the support shaft 406 is fixedly connected to the drive mechanism 5.

[0045] In use, the acrylic textile 6 is passed from front to back between the positioning rollers 403 on the first mounting frame 1, between the limiting roller 404 and the lower roller brush 401 on the first mounting frame 1, between the positioning rollers 403 on the second mounting frame 2, and between the upper roller brush 402 and the limiting roller 404 on the second mounting frame 2, so that the upper surface of the acrylic textile 6 contacts the lower side of the drive roller 405.

[0046] The drive mechanism 5 drives the support shaft 406 to rotate, which in turn drives the lower roller brush 401 on it to rotate. When the lower surface of the fabric passes through the lower roller brush 401, the lower roller brush 401 brushes the fabric to make the fabric surface pile stand up.

[0047] In one embodiment, the drive mechanism 5 includes two motors 501, which are fixedly mounted on the left side surfaces of the first mounting bracket 1 and the second mounting bracket 2, respectively. The rotation output shafts of the two motors 501 are fixedly connected to the left ends of the two support shafts 406, and the right ends of the two support shafts 406 are fixedly connected to the first gear 502.

[0048] During the forward-to-back conveying of the acrylic textile 6, the synchronously started motor 501 drives the support shaft 406 to rotate. The support shaft 406 synchronously drives the upper roller brush 402 or the lower roller brush 401 fixed on its outer surface to rotate. With the cooperation of the limiting roller 404 and the lower roller brush 401, the lower roller brush 401 brushes the lower surface of the acrylic textile 6 during its rotation. With the cooperation of the limiting roller 404 and the upper roller brush 402, the upper roller brush 402 brushes the upper surface of the acrylic textile 6 during its rotation. Then, the upper roller brush 402 and the lower roller brush 401 brush the upper and lower surfaces of the acrylic textile 6, making the fabric pile on the upper and lower surfaces of the acrylic textile 6 stand upright, which facilitates the subsequent singeing, makes the singeing effect better, and can also clean the short fibers, yarn ends, dust and other debris on the surface of the acrylic textile 6, thereby improving the practicality of the acrylic fiber pure textile pretreatment device.

[0049] In one embodiment, the singeing mechanism 7 includes a lower singeing component 701, which is fixedly mounted on the third mounting bracket 3, and an upper singeing component 702 is fixedly mounted on the second mounting bracket 2.

[0050] After the lower surface of the acrylic textile 6 is brushed with the lower roller brush 401, the acrylic textile 6 is conveyed to the upper part of the lower singeing assembly 701. At this time, the lower singeing assembly 701 is activated to singe the lower surface of the acrylic textile 6. After the lower surface of the acrylic textile 6 is singeed, it is conveyed to the upper roller brush 402 to brush the upper surface of the acrylic textile 6. After the lower surface of the acrylic textile 6 is brushed, it is conveyed to the upper singeing assembly 702. Activating the upper singeing assembly 702 allows it to singe the upper surface of the acrylic textile 6, thereby completing the singeing of the upper and lower outer surfaces of the acrylic textile 6.

[0051] In this solution, the lower singeing assembly 701 and the upper singeing assembly 702 have the same structure. The lower singeing assembly 701 is a gas singeing machine. The lower singeing assembly 701 includes a flare system, gas mixing and combustion control and other parts, which are existing public technologies and will not be described in detail here.

[0052] In one embodiment, the cleaning mechanism 8 includes a fixed rod 801, which is rotatably connected to the first mounting bracket 1 or the second mounting bracket 2. A plurality of first cleaning needles 802 are fixedly connected to the outer surface of the fixed rod 801. The first cleaning needles 802 are arranged in a central array with the fixed rod 801 as the center. A second gear 803 is fixedly connected to the right end of the fixed rod 801. The second gear 803 meshes with the first gear 502. A collection box 804 is fixedly installed on both the first mounting bracket 1 and the second mounting bracket 2.

[0053] The cleaning mechanism 8 also includes a plurality of vertical rods 805, which are fixedly connected to the bottom wall of the collection box 804. The upper ends of the plurality of vertical rods 805 are fixedly connected to a sliding plate 806, which is in the shape of an inverted "V". A plurality of second cleaning needles 807 are slidably mounted on the sliding plate 806. The upper ends of the second cleaning needles 807 extend out of the upper surface of the collection box 804. The second cleaning needles 807 and the first cleaning needles 802 are arranged alternately. The lower ends of the plurality of second cleaning needles 807 are fixedly mounted with a horizontal block 808.

[0054] The cleaning mechanism 8 also includes multiple positioning cylinders 809, which are fixedly connected to the bottom wall of the collection box 804. Multiple sliding rods 810 are fixedly installed on the lower surface of the horizontal block 808. The positioning cylinders 809 are slidably sleeved on the outer surface of the sliding rods 810. Multiple springs 811 are fixedly installed between the horizontal block 808 and the bottom wall of the collection box 804. The springs 811 are slidably sleeved on the outer surface of the corresponding positioning cylinders 809. Two pushing blocks 812 are fixedly connected to the outer surface of the fixed rod 801.

[0055] As described above, the starting motor 501 can drive the support shaft 406 to rotate. The rotation of the support shaft 406 synchronously drives the lower roller brush 401 or the upper roller brush 402 to rotate and brush the upper and lower surfaces of the acrylic textile 6. At the same time, the rotation of the support shaft 406 also drives the first gear 502 fixed on it to rotate. Since the first gear 502 is meshed with the second gear 803, the first gear 502 drives the second gear 803 to rotate. The second gear 803 synchronously drives the fixed rod 801 fixed to it to rotate, so that the fixed rod 801 synchronously drives the first cleaning needle 802 fixed on it to rotate.

[0056] During the rotation of the first cleaning needle 802, it inserts into the bristles of the upper roller brush 402 or the lower roller brush 401 and, as the first cleaning needle 802 rotates, peels off the short fibers, yarn ends and other impurities adhering to the upper roller brush 402 or the lower roller brush 401, thereby preventing yarn ends from getting tangled and affecting the brushing effect of the lower roller brush 401 or the upper roller brush 402. No manual stopping of the machine is required for cleaning, which is more labor-saving and makes the pretreatment device for acrylic fiber pure textile fabrics used in aircraft cabins more practical and flexible.

[0057] During the rotation of the fixed rod 801, the push block 12 is driven to rotate synchronously. During the rotation of the push block 12, it contacts the horizontal block 808 and pushes the horizontal block 808 downward to push the horizontal block 808 to slide downward. During the downward movement of the horizontal block 808, the sliding rod 810 is displaced downward. During the downward movement of the horizontal block 808, the spring 811 is also squeezed synchronously to deform the spring 811. When the push block 12 rotates to the point of disengaging from the horizontal block 808, the compressive stress of the spring 811 is released, thereby driving the horizontal block 808 and the sliding rod 810 to move upward and reset. Therefore, the horizontal block 808 moves up and down once for every revolution of the push block 12.

[0058] Furthermore, in practical applications, after the first cleaning needle 802 peels the yarn ends off the upper roller brush 402 or the lower roller brush 401, most of the yarn ends will fall directly into the collection box 804 as the first cleaning needle 802 rotates, while some yarn ends will become entangled on the first cleaning needle 802. Therefore, the first cleaning needle 802 needs to be cleaned. The specific cleaning process is as follows:

[0059] Because the second cleaning needle 807 is fixedly connected to the upper surface of the horizontal block 808, the horizontal block 808 moves up and down synchronously, driving the second cleaning needle 807 to move up and down as well.

[0060] In the initial state, the upper end of the second cleaning needle 807 is inserted between the two rows of first cleaning needles 802. During the rotation of the first cleaning needles 802, the second cleaning needle 807 can block the thread ends stuck to the first cleaning needles 802, causing the first cleaning needles 802 to peel off the thread ends during rotation. Because the horizontal block 808 drives the second cleaning needle 807 to move up and down, and the second cleaning needle 807 is in an "L" shape, the second cleaning needle 807 can push the yarn ends down during its downward movement, thereby preventing the yarn ends from accumulating excessively on the second cleaning needle 807. The slide plate 806 is in an inverted "V" shape, which facilitates the falling of the yarn ends into the collection box 804, thereby increasing the cleaning effect of the lower roller brush 401 or the upper roller brush 402, and thus improving the brushing effect of the lower roller brush 401 or the upper roller brush 402. There is no need for manual cleaning of the lower roller brush 401 or the upper roller brush 402, which is more labor-saving and efficient.

[0061] In this design, to ensure a clear structural principle, the number of first cleaning needles 802 and second cleaning needles 807 is relatively small, and their density is relatively sparse. In actual production, the number of first cleaning needles 802 and second cleaning needles 807 is large, and their density is high.

[0062] In summary, with the help of the above-mentioned technical solution of this utility model, the acrylic textile 6 passes sequentially through the positioning rollers 403, the limiting rollers 404 and the lower roller brush 401 on the first mounting frame 1, and the positioning rollers 403, the upper roller brush 402 and the limiting roller 404 on the second mounting frame 2, and contacts the transmission roller 405, thus achieving smooth conveying; the motor 501 drives the support shaft 406 to rotate, driving the upper roller brush 402 and the lower roller brush 401 to rotate, and with the cooperation of the limiting roller 404, brushes the upper and lower surfaces of the textile 6, making the pile stand up, and cleaning short pile, yarn ends and dust, improving the subsequent singeing effect; after the lower surface of the textile 6 is brushed, it is processed by the lower singeing component 701, and after the upper surface of the textile 6 is brushed, it is processed by the upper singeing component 702, completing the singeing of both sides of the textile. When the support shaft 406 rotates, it passes through The first gear 502 meshes with the second gear 803, driving the fixed rod 801 and the first cleaning needle 802 to rotate, peeling off the yarn ends wrapped on the upper roller brush 402 and the lower roller brush 401. The second gear 803 synchronously drives the fixed rod 801 to rotate. When the fixed rod 801 rotates, the pushing block 12 pushes the horizontal block 808 and the sliding rod 810 to move up and down reciprocally, driving the second cleaning needle 807 to move up and down, further cleaning the yarn ends remaining on the first cleaning needle 802, avoiding accumulation and ensuring cleaning effect. When the fixed rod 801 rotates, the pushing block 12 pushes the horizontal block 808 and the sliding rod 810 to move up and down reciprocally, driving the second cleaning needle 807 to move up and down, further cleaning the yarn ends remaining on the first cleaning needle 802, thereby preventing excessive accumulation of yarn ends on the second cleaning needle 807.

[0063] Through the above technical solution, 1. When the support shaft 406 rotates, the first gear 502 fixed on it drives the meshing second gear 803 to rotate, thereby driving the fixed rod 801 and the first cleaning needle 802 to rotate, peeling off the impurities wrapped on the roller brush, preventing the yarn head from affecting the brush bristle effect, realizing non-stop cleaning, and improving the practicality and flexibility of the device.

[0064] 2. When the support shaft 406 rotates, the first gear 502 fixed on it drives the meshing second gear 803 to rotate, which in turn drives the fixed rod 801 and the first cleaning needle 802 to rotate, peeling off the impurities wrapped on the roller brush, preventing the yarn head from affecting the brush bristle effect, realizing non-stop cleaning, and improving the practicality and flexibility of the device.

[0065] 3. After the acrylic textile 6 is brushed by the lower roller brush 401, the lower singeing assembly 701 processes the lower surface; after the upper surface is brushed, the upper singeing assembly 702 processes it, completing the singeing work on both sides of the textile, ensuring uniform singeing effect. The limiting roller 404 works with the roller brush to brush the lower surface of the textile 6, and works with the upper roller brush 402 to brush the upper surface, achieving synchronous processing of the upper and lower surfaces, making the pile stand up and cleaning surface impurities, improving the singeing quality and textile pretreatment effect.
