Description

Technical Field

[0001] This utility model relates to the field of weed control fabric production technology, specifically a plastic drawing machine for weed control fabric production. Background Technology

[0002] In the fields of agricultural modernization, horticulture and ecological restoration, weed control fabric, as a core material for suppressing weed growth and improving the soil environment, has become a green solution to replace traditional manual and chemical weeding due to its advantages of high weed suppression rate, good air permeability and strong weather resistance. Plastic drawing is the core process of weed control fabric production. Its principle is to make plastic flat or round filaments with a diameter of 0.1 to 1 mm by extruding, stretching and cooling plastic raw materials.

[0003] The prior art discloses an intelligent control anti-spinning plastic drawing machine with announcement number CN206085648U, which includes a main body of equipment, a winding device on the main body, five staggered winding rollers on the winding device, and an anti-spinning device installed on the winding device between two adjacent winding rollers. The plastic filament passes through the anti-spinning device, driving the driven wheel inside the anti-spinning device to rotate. The PLC controller controls the electronically controlled slide rail to adjust the plastic filament from a slack state to a taut state, preventing filament slippage. Rollers are provided inside the anti-spinning device. A servo motor controls the rotation of the rollers through a gear set, a main shaft, and a secondary shaft. The surface of the rollers is covered with an elastic rubber layer. The elastic rubber layers on the surfaces of two corresponding rollers are tightly fitted together to clamp the plastic filament.

[0004] The aforementioned plastic filament drawing machine for weed control fabric production can fix broken plastic filaments, preventing them from tangling with other unbroken filaments, thus effectively solving the shortcomings of existing technologies. However, the aforementioned plastic filament drawing machine for weed control fabric production cannot adjust the tension of the plastic film, and cannot ensure stable tension for smooth filament drawing. As a result, its performance during use is not good and needs to be improved. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This plastic filament drawing machine for weed control fabric production is equipped with a tension adjustment component. When the tension of the plastic film changes, the roller assembly deflects due to uneven force, specifically causing the second transmission wheel to shift vertically. When the tension increases, it drives the second transmission wheel to move downward, pulling the spring and increasing the filament cutting depth; conversely, it moves upward, reducing the filament cutting depth. A counterweight component, including a first counterweight block and mounting base, is installed on the front of the limiting slide. The counterweight component works in conjunction with adjusting the position of the second transmission wheel to ensure force balance, regulate the tension of the plastic film, and ensure stable tension for smooth filament drawing.

[0016] 2. This plastic filament drawing machine for weed control fabric production is equipped with a take-up and untake-down assembly. The end of the material to be drawn is fixed on the surface of the take-up drum. Then, the drive motor is started to drive the rotating shaft to rotate. During the rotation, the material is wound up. When winding up, the inner circle of the material is in contact with the surface of the anti-slip protrusion, which allows the inner circle of the material to have a gap with the take-up drum, preventing slippage and facilitating material unloading.

The first counterweight 309 is connected to the right side of the front of the limiting slide 303. The mounting base 310 is fixedly connected to the front of the first counterweight 309. The mounting base 310 has an internal threaded groove. The mounting screw 311 is threadedly connected to the inside of the mounting base 310. The second counterweight 312 is fixedly connected to the front of the mounting screw 311. The connecting base 308 is fixedly connected to the front of the second counterweight 312. The first counterweight 309 has an internal threaded mounting bolt, which is threadedly connected to the front of the limiting slide 303. The mounting bolt facilitates the fixing of the first counterweight 309. It can be installed when additional counterweight is needed and can be used normally without installation when not needed, thus increasing the adaptability of the device. The bottom of the second connecting block 306 is fixedly connected to the limiting slide plate. The width of the limiting slide plate is adapted to the left and right distance inside the limiting slide 303. The limiting slide plate is slidably connected to the inside of the limiting slide 303. The front of the limiting slide plate is fixedly connected to the bearing. The second transmission wheel 302 is fixedly connected to the inner ring of the bearing. The left side of the first counterweight 309 has a threaded groove, and the right side of the limiting slide 303 has a connecting screw hole with the same diameter as the threaded groove.

[0026] The take-up and unwind assembly 4 includes a placement plate 401, a drive motor 402, a connecting frame 403, a connecting rectangular seat 404, a rotating shaft 405, a take-up drum 406, and an anti-slip protrusion 407. The drive motor 402 is fixedly connected to the back of the front placement plate 401, the connecting frame 403 is fixedly connected to the back of the front placement plate 401, the connecting rectangular seat 404 is fixedly connected to the back of the connecting frame 403, the drive motor 402 is fixedly connected to the front of the connecting rectangular seat 404, and the rotating shaft 405 is fixedly connected to the drive motor 406.

[0027] In use, the end of the material to be drawn is fixed to the surface of the take-up drum 406. Then, the drive motor 402 is started to drive the rotating shaft 405 to rotate. During the rotation, the material is wound up. During winding, the inner ring of the material contacts the surface of the anti-slip protrusion 407, which allows for a gap between the inner ring of the material and the take-up drum 406, preventing slippage and facilitating unloading. During winding, the bottom of the material slides against the top of the first transmission wheel 301 and the second transmission wheel 302. The height of the second transmission wheel 302 can be adjusted to adjust the tension of the material. When the tension of the film changes, the roller assembly deflects at an angle due to uneven force. Specifically, the second transmission wheel 302 shifts vertically. When the tension increases, it drives the second transmission wheel 302 to move downward, pulling the spring 307 and increasing the slitting depth. Conversely, it moves upward, reducing the slitting depth. The front of the limiting slide 303 is equipped with a counterweight assembly, including a first counterweight block 309 and a mounting base 310. The counterweight assembly works in conjunction with adjusting the position of the second transmission wheel 302 to ensure force balance and adjust the tension of the plastic film, ensuring stable tension and thus stable slitting processing.
