Description

Technical Field

[0001] This utility model relates to the technical field of nonwoven fabric production, specifically a composite mechanism for nonwoven fabric production. Background Technology

[0002] UD non-woven bulletproof fiber composite material is a resin-based composite material with fiber as the reinforcing material. It has excellent physical and mechanical properties and good kinetic energy absorption, thus possessing excellent bulletproof performance.

[0003] The current production process for UD nonwoven fabric involves first making the fibers into longitudinal sheets, then making the longitudinal sheets into transverse sheets, and finally making them into 2UD composite sheets through a specific process. For details, please refer to the utility model patent: CN 112793284A "A production process and production line for double-layer nonwoven fabric". However, in the production process of nonwoven fabric, multiple groups of yarns on the yarn frame need to be gathered to form a plane and then coated with adhesive. The plane yarns mixed with adhesive need to pass evenly through the drying and setting mechanism before they can become nonwoven fabric. In the existing process, multiple groups of yarns are gradually driven to the traction and flattening system after passing through the transition yarn frame. When actually leveling the yarns in the height direction and aligning them in the width direction, multiple traction settings are required, which results in a long production line. Moreover, in actual use, the setting of multiple traction devices cannot reliably level the numerous yarns. Therefore, additional yarn spreading equipment is required at the rear. Thus, the existing technology cannot reliably guide multiple yarns to form a single-layer yarn thickness plane in a short distance, resulting in a long composite stroke for nonwoven fabric and high manufacturing cost of the nonwoven fabric composite mechanism. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a composite mechanism for the production of non-woven fabrics, which rapidly guides multiple sets of yarns to form a planar shape with a single layer of yarn thickness, resulting in a shorter composite stroke for the non-woven fabric and reducing the cost of the composite mechanism.

[0005] A composite mechanism for producing nonwoven fabrics, characterized in that it comprises:

[0006] A yarn rack, on which a corresponding number of yarn rolls are set;

[0007] A yarn guide frame includes a vertical support, a front guide plate, and a rear guide plate. Both the front and rear guide plates are arranged horizontally. The front guide plate has a number of guide holes spaced apart in the width direction. The rear guide plate is provided with a through slit. The height spacing of the through slit is set according to the diameter of the yarn.

[0008] Front traction mechanism;

[0009] Glue application mechanism;

[0010] Diaphragm unwinding mechanism;

[0011] Drying and shaping mechanism;

[0012] And the receiving agency;

[0013] Each row of yarns on the yarn frame flows out after passing through the guide hole at the corresponding position of its front guide plate. Then, all the yarns pass through the through-slit at the corresponding width position to obtain a planar shape with a single layer of yarn thickness. The planar shape of the single layer of yarn thickness is then transported to the glue-applying mechanism at the rear after the fiber tension is adjusted by the front traction mechanism. The glue-applying mechanism is located above and below the yarn layer. The film unwinding mechanism unwinds and outputs the PE film. The single layer of yarn adheres tightly to the PE film and enters the drying and setting mechanism. After the PE film and the single layer of yarn are dried and positioned by the drying and setting mechanism, they are wound up by the winding mechanism.

[0014] Its further features are:

[0015] The corresponding front guide plate and rear guide plate are connected by a connecting plate to form an integral guide plate group. The vertical bracket is arranged with several sets of placement partitions of different heights along the height direction. Positioning holes are provided at both ends of the connecting plate of the integral guide plate group in the length direction. The two placement partitions of the corresponding heights are fixedly installed by connecting screws to the integral guide plate group.

[0016] According to the production line requirements, multiple sets of integrated guide plate groups are set up. The number and diameter of the guide holes of the front guide plate of each group are set according to the number and diameter of the yarn. The height, spacing and length of the through-slit of each rear guide plate are set according to the number and diameter of the yarn. This makes the entire composite mechanism suitable for the production of different types of non-woven fabrics.

[0017] The gluing mechanism, film unwinding mechanism, and drying and shaping mechanism share a single frame, saving on equipment costs for the laminating mechanism;

[0018] The gluing mechanism is located at the front end of the frame. The gluing mechanism includes an upper gluing roller and a lower gluing roller, which allows the yarn layer to reliably pass through the upper gluing roller and the lower gluing roller. A glue recycling mechanism is also provided below the lower gluing roller.

[0019] The film unwinding mechanism is provided with film winding rollers and film guide rollers along the upper layer of the frame, and the last film guide roller guides the PE film to the input end of the drying and shaping mechanism.

[0020] The drying and shaping mechanism is specifically a heated rotating roller. The outer roller surface of the heated rotating roller rotates clockwise to guide the PE film and the yarn layer coated with adhesive to the rear guide output roller. After that, the formed non-woven fabric passes through the guide output roller and is then wound up by the winding mechanism.

[0021] After adopting the above technical solution, each row of yarns on the yarn frame flows out after corresponding to the guide hole at the corresponding position of its front guide plate. Then, all the yarns pass through the through-slit at the corresponding width position to obtain a planar shape with a single layer of yarn thickness. The planar shape of the single layer of yarn thickness is transported to the glue-applying mechanism after the fiber tension is adjusted by the front traction mechanism. The glue-applying mechanism is located above and below the yarn layer. The film unwinding mechanism unwinds and outputs the PE film. The single layer of yarn adheres tightly to the PE film and enters the drying and setting mechanism. After the PE film and the single layer of yarn are dried and positioned by the drying and setting mechanism, they are wound up by the winding mechanism. This quickly guides multiple sets of yarns to form a planar shape with a single layer of yarn thickness, which shortens the composite stroke of the non-woven fabric and reduces the cost of the composite mechanism.

Detailed Implementation

[0028] A composite mechanism for the production of nonwoven fabrics, see Figures 1-3 It includes a yarn frame 10, a yarn guide frame 20, a front traction mechanism 30, an adhesive application mechanism 40, a film unwinding mechanism 50, a drying and shaping mechanism 60, and a winding mechanism 70.

[0029] The yarn rack 20 is equipped with a corresponding number of yarn rolls;

[0030] The yarn guide frame 20 includes a vertical support 21, a front guide plate 22, and a rear guide plate 23. Both the front guide plate 22 and the rear guide plate 23 are arranged horizontally. The front guide plate 22 has a number of guide holes 221 arranged at intervals in the width direction. The rear guide plate 23 is provided with a through slit 231. The height spacing of the through slit 231 is set according to the diameter of the yarn 1.

[0031] Each row of yarns 1 on the yarn frame 10 flows out after passing through the guide hole 221 at the corresponding position of its front guide plate 22. After that, all the yarns 1 pass through the through-slit 231 at the corresponding width position to obtain a planar shape of single-layer yarn thickness. The single-layer yarn planar shape is transported to the glue-applying mechanism 40 after the fiber tension is adjusted by the front traction mechanism 30. The glue-applying mechanism 40 is located above and below the yarn layer. The film unwinding mechanism 50 unwinds and outputs the PE film. The single-layer yarn layer is closely attached to the PE film and enters the drying and setting mechanism 60. After the PE film and the single-layer yarn are dried and positioned by the drying and setting mechanism 60, they are wound up by the winding mechanism 70.

[0032] In a specific embodiment, the corresponding front guide plate 22 and rear guide plate 23 are connected by a connecting plate 24 to form an integral guide plate group 26. The vertical bracket 21 arranges several sets of placement partitions 25 of different heights along the height direction. Positioning holes are respectively provided at both ends of the length direction of the connecting plate 24 of the integral guide plate group 26. The two placement partitions 25 of the corresponding heights are fixedly installed by connecting screws.

[0033] According to the production line requirements, multiple sets of integrated guide plate groups 26 are set up. The number and diameter of the guide holes 221 of the front guide plate 22 of each set of guide plate groups 26 are set according to the number and diameter of the yarn. The height spacing and length of the through seam 232 of each set of rear guide plates 23 are set according to the number and diameter of the yarn. This makes the entire composite mechanism suitable for the production of different types of non-woven fabrics.

[0034] In a specific embodiment, the gluing mechanism 40, the film unwinding mechanism 50, and the drying and shaping mechanism 60 share a single frame 80, which saves on the equipment cost of the laminating mechanism;

[0035] The gluing mechanism 40 is located at the front end of the frame 80. The gluing mechanism 40 includes a gluing roller 41 and a lower gluing roller 42, which allows the yarn layer to reliably pass through the gluing roller 41 and the lower gluing roller 42. A glue recycling mechanism 43 is also provided below the lower gluing roller 42.

[0036] The film unwinding mechanism 50 is provided with a film winding roller 51 and a film guide roller 52 along the upper layer of the frame 80. The film guide roller 52 at the very end guides the PE film to the input end of the drying and shaping mechanism 60.

[0037] The drying and setting mechanism 60 is specifically a heated roller 61. The outer roller surface of the heated roller 61 rotates clockwise to guide the PE film and the yarn layer coated with adhesive to the rear guide output roller 62. After that, the formed non-woven fabric passes through the guide output roller 62 and is then wound up by the winding mechanism 70.

[0038] Its working principle is as follows: Each row of yarns on the yarn frame flows out after passing through the guide hole corresponding to the position of its respective front guide plate. Then, all the yarns pass through the through-slit at the corresponding width position to obtain a planar shape with a single layer of yarn thickness. The planar shape of the single layer of yarn thickness is transported to the glue-applying mechanism after the fiber tension is adjusted by the front traction mechanism. The glue-applying mechanism is located above and below the yarn layer. The film unwinding mechanism unwinds and outputs the PE film. The single layer of yarn adheres tightly to the PE film and enters the drying and setting mechanism. After the PE film and the single layer of yarn are dried and positioned by the drying and setting mechanism, they are wound up by the winding mechanism. This quickly guides multiple sets of yarns to form a planar shape with a single layer of yarn thickness, which shortens the composite stroke of the non-woven fabric and reduces the cost of the composite mechanism.
