Description

Technical Field

[0001] The utility model belongs to the technical field of direct yarn production, and in particular relates to a bundling device for producing micro-bulked direct yarn. Background Art

[0002] The existing 600tex direct yarn is produced by 4800H leaky plate, using the three-part drawing and one-in-one process. The product tow width is 2.0-2.3mm, with good bundling. It needs to be pressurized with 0.45MPa compressed air to be expanded before it can be put into use for manufacturing automotive sheets. Because the tow width of the produced direct yarn is too narrow, the product bundling is too good and it is not easy to disperse, the compressed air pressure once exceeded 0.45MPa, resulting in excessively high production costs. Therefore, a micro-bulked direct yarn is urgently needed to replace the bulking process and reduce costs.

[0003] Existing production processes such as Figure 7 As shown, the tow flows down from the 4800H leak plate 1 and becomes glass fiber. After passing through the oiling roller 2, it is divided into three bundles by three first-bundle collecting wheels 17. Each bundle passes through a second-bundle collecting wheel 18 and is wound on the three-dividing wire drawing machine through a wire arrangement shuttle. One bundle is wound into a wire cake. The second collecting wheel is at a certain distance from the center of the leak plate to ensure the tension of the tow while controlling the tow to enter the corresponding position of the drawing machine head. The wire arrangement shuttle controls the movement of the tow within a certain range and winds it into a wire cake. The copper rod of the wire arrangement box is under the shuttle. Its function is to lift the tow in the middle of the shuttle mouth to prevent the tow from wearing the root of the shuttle mouth, and the copper rod cannot touch the wire cake. Figure 8 As shown, otherwise the wire cake will be squeezed and deformed and cause the wire drawing machine to lock. Among them, the distance between the second bunching wheel and the center line of the leak plate is 680mm, the wire arranging shuttle is a 1mm opening shuttle, the bundle drawing is a three-part drawing-in-one process, the winding ratio is 6.432673, and the distance between the wire arranging copper rod and the wire cake is 2mm.

[0004] For example, the Chinese utility model patent with authorization announcement number CN215828024U discloses a direct yarn bundling device, which has the following shortcomings: the angle of the yarn bundle at the second bundling wheel to the yarn receiving machine is too large, which will cause the yarn guide device at the yarn receiving machine to wear the yarn bundle more, easily produce lint and broken yarn, and easily cause the yarn to break; in addition, the yarn receiving machine head needs to be constantly moved up and down to arrange the yarn to be entangled on the machine head, which causes greater wear on the yarn. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a bundling device for producing micro-bulked direct yarns.

[0006] In order to achieve the above purpose, the utility model is implemented by adopting the following technical solutions:

[0007] A bundling device for producing micro-bulked direct yarn comprises a leak plate, an oiling roller, a three-beam bundling wheel, a screw stop device and a wire arranging box through which the yarn bundles pass in sequence. The three-beam bundling wheel is mounted on a bundling wheel mounting shaft, the screw stop device is mounted on a fixed plate, a wire arranging box copper rod is provided on one side of the wire arranging box, and two ends of the wire arranging box copper rod are elastically connected to two ends of the wire arranging box through spring retractors.

[0008] Preferably, the screw rod blocking device comprises a fixing seat, two mounting grooves are extended toward the center on both sides of the fixing seat, sleeves are installed at the ends of the mounting grooves, and a guide rod is installed in the sleeve.

[0009] Preferably, a butterfly bolt is installed through one end of the installation slot away from the guide rod. The installation slot is locked by the butterfly bolt, thereby locking the sleeve to prevent the sleeve and the guide rod from jumping out.

[0010] Preferably, the fixing seat is connected to the fixing plate by bolts.

[0011] Preferably, the screw stop devices are provided at three locations, and the three screw stop devices are evenly installed on the fixing plate.

[0012] Preferably, the guide rod is a carbon rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Design a spring-loaded copper rod for the wire-drawing box to replace the existing fixed copper rod. The existing copper rod for the wire-drawing machine is fixed. During wire drawing, the copper rod cannot squeeze the wire cake to prevent deformation of the wire cake and failure of the wire drawing machine. Through the spring-loaded copper rod for the wire-drawing box, the distance between the copper rod for the wire-drawing box and the wire cake is changed from the existing 2mm to 0, so that the copper rod for the wire-drawing box touches the wire cake without a gap. When the copper rod for the wire-drawing box is subjected to slight pressure, it can move forward and backward. In this way, during the wire drawing process, the copper rod for the wire-drawing box can slightly squeeze the wire cake to flatten the wire bundle, while ensuring that the wire cake is not deformed by slight squeezing force, and the wire drawing machine does not have a locking failure. At the same time, the spring-loaded copper rod for the wire-drawing box can further flatten the wire bundle to make the wire bundle width reach more than 3.0, and reduce the thickness of the wire bundle to be as thin as a cicada's wing, thereby reducing the bundle clustering of the wire bundle.

[0015] 2. The three-beam bunching wheel replaces the existing single-beam R10-U wheel, that is, the three-in-one process replaces the one-in-one process, which reduces the product's bunching and ensures the product's dispersion; the tow is evenly directed downward, the lateral tension of the tow is reduced, the full-bobbin rate of the drawing is increased, and the tow width is increased from 2.0mm to 2.7mm;

[0016] 3. The existing second bunching wheel is replaced by a screw rod device to fix the range of the wire bundle for easy wire drawing, while reducing the wire drawing tension and the product bunching. Compared with the traditional process, the wire bundle width is increased from 2.0mm to 2.6mm; at the same time, the guide rod is a rotatable carbon rod, and the wire bundle of each wire cake passes through the middle of two rotatable carbon rods. The carbon rod plays the role of fixing the position of the corresponding wire cake, and the rotation can reduce the friction of the carbon rod on the wire bundle;

[0017] To sum up, the utility model enables the yarn bundle to achieve a micro-bulking effect, the yarn bundle width is greater than 3.0mm, the product bundling is reduced, and it is convenient for customers to use directly. Compressed air bulking is no longer used, which reduces the customer's use cost. It can be widely used in glass fiber direct yarn bulking production process products, and can cancel the direct yarn bulking process. The product directly achieves a micro-bulking effect and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0028] Embodiment 1:

[0029] like Figure 1 , 4 As shown, a bundling device for producing micro-bulked direct yarn includes a leak plate 1, an oiling roller 2, a three-beam bundling wheel 3, a screw stop device 6 and a wire arranging box 8 through which the yarn bundles pass in sequence, the three-beam bundling wheel 3 is installed on the bundling wheel installation shaft 4, the screw stop device 6 is installed on the fixed plate 5, and a wire arranging box copper rod 15 is provided on one side of the wire arranging box 8, and the two ends of the wire arranging box copper rod 15 are elastically connected to the two ends of the wire arranging box 8 through spring retractors 14.

[0030] In this embodiment, the glass liquid flows down from the 4800H leak plate 1 and becomes glass fiber. After passing through the oiling roller 2, it is divided into nine bundles by three three-beam bundling wheels 3. Every three bundles are then controlled by a group of screw blocking rod devices 6 on the corresponding drawing cylinder positions of the three-beam drawing machine below. The wire arrangement is controlled by a 5mm large opening wire arrangement shuttle, and the wire bundles are squeezed and wound on the wire drawing machine by the spring-loaded wire arrangement box copper rod 15.

[0031] Furthermore, the present embodiment designs a spring-loaded copper rod 15 to replace the existing fixed copper rod. The existing copper rod 15 of the wire drawing machine wire drawing box is fixed. When drawing wires, the copper rod 15 of the wire drawing box cannot squeeze the wire cake 9 to prevent the wire cake 9 from deforming and causing the wire drawing machine to malfunction. Figure 5 As shown, the copper rod 15 of the wire arranging box is fixed with a spring retractor 14, and the copper rod 15 of the wire arranging box can be moved forward and backward under slight pressure, so that during the wire drawing process, the copper rod 15 of the wire arranging box can slightly squeeze the wire cake 9 to flatten the wire bundle, while ensuring that the wire cake 9 does not deform under slight squeezing force, and the wire drawing machine does not have a locking fault. The spring-pressure wire arranging box copper rod 15 can further flatten the wire bundle, making the wire bundle width reach more than 3.0, and reduce the thickness of the wire bundle, as thin as a cicada's wing, and reduce the bundle clustering.

[0032] At the same time, if Figure 6 As shown, the three-beam bunching wheel 3 replaces the existing single-beam R10-U wheel, that is, the three-in-one process is used to replace the one-in-one process, which reduces the bundling of the product and ensures the dispersion of the product; the yarn bundles are evenly directed downward, the lateral tension of the yarn bundles is reduced, the full-bobbin rate of the wire drawing is increased, and the yarn bundle width is increased from 2.0mm to 2.7mm.

[0033] Embodiment 2:

[0034] like Figure 2-3 As shown, a bundling device for producing micro-bulked direct yarn is different from Example 1 in that the screw blocking rod device 6 includes a fixed seat 10, and two mounting grooves 13 are extended from both sides of the fixed seat 10 toward the center, and sleeves 16 are installed at the ends of the mounting grooves 13, and guide rods 7 are installed in the sleeves 16. Further, the guide rods 7 are carbon rods.

[0035] In this embodiment, the existing second bunching wheel is replaced by a wire blocking rod device 6, and the movable range of the wire bundle is fixed to facilitate wire drawing, while reducing the wire drawing tension and reducing the bundling of the product. Compared with the traditional process, the wire bundle width is increased from 2.0 mm to 2.6 mm; at the same time, the guide rod 7 is a rotatable carbon rod, and the wire bundle of each wire cake 9 passes between two rotatable carbon rods. The carbon rod serves to fix the position of the corresponding wire cake 9, and rotation can reduce the friction of the carbon rod on the wire bundle.

[0036] Further, a butterfly bolt 11 is installed from top to bottom through one end of the mounting groove 13 away from the guide rod 7. The mounting groove 13 is locked by the butterfly bolt 11, thereby locking the sleeve 16 to prevent the sleeve 16 and the guide rod 7 from escaping.

[0037] Furthermore, the fixing seat 10 is connected to the fixing plate 5 via bolts 12 .

[0038] Furthermore, three screw stop devices 6 are provided, and the three screw stop devices 6 are evenly installed on the fixing plate 5 .

[0039] The working principle of the utility model is:

[0040] For example Figure 1-6 As shown, when the utility model is installed and used, the leak plate 1, the oiling roller 2, the bunching wheel mounting shaft 4, and the fixed plate 5 are installed on the top of both sides of the factory building through the fixing frame in sequence, the three-beam bunching wheel 3 is installed on the bunching wheel mounting shaft 4, and the three screw stop devices 6 are evenly installed on the fixed plate 5. At the same time, the wire arrangement box copper rod 15 touches the wire cake 9. After the installation is completed, before the first use, the glass liquid first flows down from the 4800H leak plate 1 to become glass fiber, and after passing through the oiling roller 2, it is divided into nine bundles by the three three-beam bunching wheels 3, and then every three bundles are manually passed through two guide rods 7 in a group of screw stop devices 6, and the wire arrangement is controlled by the 5mm large opening wire arrangement shuttle, and the wire bundles are squeezed and wound on the wire drawing machine by the spring-pressure wire arrangement box copper rod 15.

[0041] In addition, in order to further increase the width of the tow and reduce the problems of wire skipping and unwinding of the product end face, the winding ratio is designed to be 8.440203. The design theory is: reduce the shuttle operation cycle, reduce the shuttle operation speed to reduce the tension of the tow, and wind it in a strip shape at the shuttle to increase the bandwidth, while ensuring that the product is formed and unwinding without unwinding. The wire arrangement shuttle is designed to be 5.0mm, replacing the existing 1.0 wire arrangement shuttle, increasing the wire entry width of the tow head, reducing the product bundling, and increasing the tow width from 2.0mm to 2.8mm.
