Description

Technical Field

[0001] This utility model relates to the technical field of nylon fishing line manufacturing equipment, and in particular to a highly stable monofilament drawing device. Background Technology

[0002] The manufacturing process of nylon fishing line requires extrusion molding through a drawing device, which includes an extruder, a cooling device, and a traction device arranged in sequence. The extruder melts nylon particles through a heating system and extrudes them in the form of fine strips. The extruded filaments are then continuously drawn by the traction device through the cooling device and wound up.

[0003] In existing wire drawing devices, the traction mechanism also includes an adjusting pressure roller for adjusting the traction force. With the traction roller and extruder output speed remaining constant, the tension of the wire is changed by adjusting the pressure roller, thereby adjusting the thickness of the formed wire. Traditionally, the adjusting pressure roller is mounted movably using a swing arm bracket, and its vertical angle is adjusted manually.

[0004] This traditional adjustable pressure roller has the following disadvantages: low adjustment accuracy; long debugging time and high debugging cost; no specific gear is set, and repeated debugging is required when producing nylon fishing line of different specifications, which is very inconvenient. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a highly stable monofilament drawing device to solve the above-mentioned disadvantages.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-stability monofilament drawing device, comprising an extrusion device, a cooling device, and a traction device arranged sequentially. The traction device has a traction roller, and the extrusion device has an extrusion head. The filament extruded by the extrusion head is continuously output through the cooling device and wound onto the traction roller. The traction device is also equipped with a tensioning device, which has a lifting bracket, a lifting movable seat, a lifting guide rod, a lifting adjusting screw, and a lifting drive motor. The lifting bracket is located in front of the traction roller. The lifting guide rod is vertically fixed to the lifting bracket.

A tensioning guide wheel is rotatably installed on the side of the lifting movable seat, and the tensioning guide wheel applies pressure to the filament.

[0007] In a further technical solution, a lifting bracket is provided on the input side of the traction equipment, and a lifting guide roller is provided on the top of the lifting bracket. The height of the tension guide roller is always lower than that of the lifting guide roller.

[0008] In a further technical solution, the traction equipment also includes a traction drive housing, a traction drive shaft is provided on one side of the traction drive housing, a traction drive motor is connected to the traction drive shaft, and the traction drive motor is located inside the traction drive housing; the traction roller is movably sleeved on the traction drive shaft, and a locking structure is provided between the two, the locking structure including a linkage key structure.

[0009] In a further technical solution, a transverse winding adjustment mechanism is provided on the upper part of the traction roller. The transverse winding adjustment mechanism includes a transverse drive motor, a transverse drive screw, a transverse guide rod, and a transverse movable seat. The transverse drive motor is located inside the traction drive housing. One end of the transverse drive screw is rotatably mounted on the side of the traction drive housing and is connected to the transverse drive motor. Two transverse guide rods are provided, located on both sides above the transverse drive screw. These two transverse guide rods and the transverse drive screw are parallel to the traction drive shaft. Connecting parts are provided on both sides of the transverse movable seat, and they are slidably connected to the corresponding transverse guide rods through the connecting parts. The transverse movable seat is provided with another screw pair, which is threadedly connected to the transverse drive screw. An extension bracket is provided on the front side of the transverse movable seat, and a transverse guide wheel is provided at the end of the extension bracket. The height of the transverse guide wheel is always higher than that of the tension guide wheel.

[0010] In a further technical solution, the top of the extrusion equipment is provided with a feeding tray, an extruder, and an extrusion head. The output end of the feeding tray is connected to the feed end of the extruder, and the extrusion head is located on the front side of the extruder. The extrusion head is provided with an extrusion bend, which is bent downwards and forwards to reduce the output direction of the molten filament towards the cooling equipment and reduce the probability of breakage due to bending.

[0011] In a further technical solution, a cooling water basin is provided on the top of the cooling equipment. The cooling water basin is filled with cooling water and is made of stainless steel. The cooling water basin extends along the layout direction of the whole machine. Inside the cooling water basin, multiple parallel cooling rollers are arranged along its length. The cooling rollers are immersed in the cooling water. The wire passes through the cooling water basin along its length and is rolled on the underside of each cooling roller to keep it immersed in the cooling water.

[0012] In a further technical solution, the cooling equipment is equipped with a refrigeration device, which includes a condenser.

[0015] The advantages of this invention compared to the prior art after adopting the above structure are: 1. A tensioning device has been added to the traction equipment. This device includes a lifting bracket, a lifting movable seat, a lifting guide rod, a lifting adjusting screw, and a lifting drive motor. The motor drives the screw pair to move the lifting movable seat up and down precisely, thereby adjusting the pressure and tension of the tensioning guide wheel on the movable seat on the yarn. This achieves precise electric control of the yarn tension and avoids the problems of low adjustment accuracy and poor repeatability of the traditional manual swing arm type pressure roller adjustment.

[0016] 2. Compared to traditional technologies that require repeated manual adjustment of the pressure roller angle or position, this solution's electric lifting adjustment method can quickly set the optimal tension value according to different yarn specifications, reducing debugging time, improving production changeover efficiency, and reducing labor costs and debugging difficulty.

[0017] 3. The extrusion tube of the extruder is bent forward and downward, which allows the high-temperature molten filament extruded from the extruder to be guided to the cooling equipment in a more natural path. This reduces the stress concentration and breakage risk caused by sharp turns or right-angle bends in the filament, and helps to improve the quality of filament forming and the stability of continuous production.

[0018] 4. The cooling water basin is equipped with a refrigeration device consisting of a condenser at the bottom, which can accurately control the temperature of the cooling water within a preset range, avoiding unstable cooling effect of the wire due to water temperature fluctuations, thereby further improving the dimensional accuracy and physical property consistency of the wire.

[0028] Compared to traditional technologies that require repeated manual adjustments to the angle or position of the pressure rollers, this solution's electric lifting adjustment method can quickly set the optimal tension value according to different yarn specifications, reducing debugging time, improving production changeover efficiency, and lowering labor costs and debugging difficulty.
