Description

Technical Field

[0001] This utility model relates to the field of fabric production technology, and in particular to an aramid nonwoven fabric production line. Background Technology

[0002] Aramid nonwoven fabric is made of aramid fibers and PE film. It possesses excellent properties such as soft hand feel, low density, abrasion resistance, impact resistance, and strong cut toughness. The product is widely used in special public riot control applications such as soft bulletproof vests, lightweight bulletproof helmets, and lightweight bulletproof armor plates.

[0003] Currently, after the production of aramid nonwoven fabric is completed, it is wound up by the take-up roller in the production line. However, the take-up roller in the existing aramid nonwoven fabric production line is often fixed to the drive component with multiple bolts. This means that when the workers disassemble and replace it, they need to unscrew multiple bolts one by one. This makes it inconvenient to quickly disassemble and replace the take-up roller, and it cannot achieve quick fabric replacement, which reduces the production efficiency of aramid nonwoven fabric. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing an aramid nonwoven fabric production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A production line for aramid nonwoven fabric includes: a frame; a rotating shaft slidably inserted into the outer side of the frame, with a take-up roller fixedly fitted on the surface of the rotating shaft; two insertion slots are provided on the outer side of the frame, and the insertion slots match the rotating shaft; a snap-fit ​​assembly including a groove formed in the bottom of the frame, an electromagnet fixedly installed at the bottom of the groove, a magnetic block repelling above the electromagnet, a movable plate fixedly installed on the other side of the magnetic block, and the two ends of the movable plate slidingly passing through the two sides of the frame; two symmetrically fixedly installed positioning pins on the top of the movable plate, and the two positioning pins slidingly passing through the two insertion slots; and a drive assembly for driving the rotating shaft to rotate.

[0006] Preferably, the drive assembly includes a fixed plate fixedly installed in the frame, a dual-axis motor fixedly installed on the top of the fixed plate, drive shafts fixedly installed on both drive ends of the dual-axis motor, gear discs fixedly installed on opposite ends of the two drive shafts respectively extending through to both sides of the frame, gears meshing on the outer sides of the two gear discs, and the two gears fixedly installed at both ends of the rotating shaft respectively.

[0007] Preferably, sliding holes are provided on both sides of the frame, and the sliding holes are slidably connected to the moving plate.

[0008] Preferably, both of the insertion slots have a positioning slot at the top, and the positioning slot is inserted into or separated from the positioning pin.

[0009] Preferably, two springs are connected between the bottom of the movable plate and the bottom of the groove.

[0010] Preferably, both of the insertion slots are inclined.

[0011] Compared with existing technologies, the advantages of this utility model are: When the power is on, the electromagnet repulses the magnetic block, pushing the moving plate upwards. This causes the two positioning pins to insert into the two insertion slots and contact the surface of the rotating shaft, thus restricting the rotating shaft and completing the quick installation of the take-up roller. Conversely, when the power is off, the moving plate, under its own weight and the tension of the two springs, moves the two positioning pins downwards to the bottom of the insertion slots. At this point, the operator can directly pull out the take-up roller to complete the quick disassembly of the take-up roller. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1 to 3A production line for aramid nonwoven fabric includes: a frame 1; a rotating shaft 2 slidably inserted into the outer side of the frame 1, with a take-up roller 3 fixedly fitted onto the surface of the rotating shaft 2; two insertion slots 4 are provided on the outer side of the frame 1, and the insertion slots 4 match the rotating shaft 2; both insertion slots 4 are inclined to facilitate the initial positioning of the rotating shaft 2 within the insertion slots 4 after insertion, ensuring stability before being restricted; and a locking assembly including a groove 5 formed at the bottom of the frame 1, with an electromagnet 6 fixedly installed at the bottom of the groove 5, a magnetic block 7 repelling above the electromagnet 6, and a movable plate 8 fixedly installed on the other side of the magnetic block 7. Two springs 9 are connected between the bottom of the movable plate 8 and the bottom of the groove 5, which facilitates the downward movement and reset of the movable plate 8. The two ends of the movable plate 8 slide through the two sides of the frame 1. Sliding holes 15 are provided on both sides of the frame 1, and the sliding holes 15 are slidably connected to the movable plate 8. Two positioning pins 10 are symmetrically fixedly installed on the top of the movable plate 8, and the two positioning pins 10 slide through the two insertion grooves 4 respectively. After the positioning pins 10 are inserted into the insertion grooves 4, the surface of the positioning pins 10 contacts the surface of the rotating shaft 2. By pressing the rotating shaft 2 against the bottom of the insertion groove 4, the rotating shaft 2 can be restricted, and the installation of the take-up roller 3 can be completed.

[0016] The drive assembly is used to drive the rotating shaft 2 to rotate. The drive assembly includes a fixed plate 16 fixedly installed in the frame 1. A dual-axis motor 11 is fixedly installed on the top of the fixed plate 16. A drive shaft 12 is fixedly installed on each of the two drive ends of the dual-axis motor 11. A gear disk 13 is fixedly installed on each side of the frame 1 at the opposite ends of the two drive shafts 12. Gears 14 are meshed on the outer sides of the two gear disks 13. The two gears 14 are fixedly installed at both ends of the rotating shaft 2. When the dual-axis motor 11 is started, it drives the two gear disks 13 to rotate through the two drive shafts 12. Then, the gears 14 meshing with them drive the rotating shaft 2 and the winding roller 3 to rotate synchronously, so as to wind up the aramid nonwoven fabric.

[0017] The top of each of the two insertion slots 4 is provided with a positioning slot 17, and the positioning slot 17 is inserted into or separated from the positioning pin 10, which can effectively improve the firmness of the positioning pin 10 when it is inserted into the insertion slot 4.
