Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a plastic woven bag drawing device, comprising:

[0024] Cold water frame 1, with a fixed frame 2 fixedly provided on one side of the outer wall of cold water frame 1;

[0025] The bag clamping structure has two clamping structures, both of which are located within the fixed frame 2;

[0026] Each bag clamping structure includes two threaded rods 3 and two clamping plates 4. The outer walls of the two threaded rods 3 are rotatably embedded in the fixed frame 2. The two ends of the outer walls of the two clamping plates 4 are respectively threaded onto the two threaded rods 3. The top of the outer walls of the two threaded rods 3 are fixedly provided with a main rotating disk 5.

[0027] A wire drawing structure is provided between the cold water frame 1 and the fixed frame 2;

[0028] The wire drawing structure includes a main connecting plate 6, a fixing strip 7, two connecting rods 8, and a secondary connecting plate 9. The outer wall of the main connecting plate 6 is fixed between the cold water frame 1 and the fixing frame 2. The outer walls of the two connecting rods 8 are slidably embedded in the main connecting plate 6. One end of each of the two connecting rods 8 is fixed on the fixing strip 7, and the other end of each of the two connecting rods 8 is fixed on the secondary connecting plate 9.

[0029] In this implementation scheme: the cold water frame 1 contains cold water, which can quickly cool the extruded woven bag film, thus facilitating the drawing process. The fixed frame 2 can symmetrically fix the bag clamping structure. Controlling the rotation of the main rotating disk 5 can drive the rotation of the threaded rod 3, thereby using the thread to control the two clamping plates 4 to move closer and further apart, thus clamping the woven bag film. The moving woven bag film, moving between the two clamping plates 4, can remove water from the surface of the woven bag film while tightening the woven bag film, thus making the tension of the drawing uniform, so that the cutter can produce uniform and continuous ribbons after acting on the woven bag film. The two connecting rods 8 can fix the fixed strip plate 7 and the secondary connecting plate 9 together, while sliding stably on the main connecting plate 6.

[0030] Specifically, the wire drawing structure also includes a wire drawing knife 10, a rotating rod 11, and a secondary rotating disk 12. The top of the outer wall of the wire drawing knife 10 is fixed on the fixed strip plate 7.

[0031] In this embodiment, the drawing knife 10 can act on the surface of the woven bag film to produce a uniform and continuous ribbon.

[0032] Specifically, the outer wall of the rotating rod 11 is threaded into the auxiliary connecting plate 9, one end of the rotating rod 11 is rotatably embedded in the main connecting plate 6, and the other end of the rotating rod 11 is fixedly mounted on the auxiliary rotating disk 12.

[0033] In this embodiment: the auxiliary rotating disk 12 can drive the rotating rod 11 to rotate, and the auxiliary connecting plate 9 can be moved up and down by using the threaded upper and lower control.

[0034] Specifically, the inner wall of the fixed frame 2 is fixedly provided with an installation frame 13, and multiple protective nets 14 are fixedly embedded at equal intervals on the top of the outer wall of the installation frame 13.

[0035] In this embodiment, the mounting frame 13 can fix multiple fan frames 15, while multiple protective nets 14 can prevent foreign objects from entering the mounting frame 13.

[0036] Specifically, multiple fan frames 15 are fixedly embedded at equal intervals on the inner wall of the mounting frame 13, and fan motors 16 are installed on the inner walls of the multiple fan frames 15.

[0037] In this embodiment, the fan motor 16 can generate wind when it is powered on, thereby causing the water on the wire drawing surface to evaporate quickly.

[0038] Specifically, the inner wall of the cold water frame 1 is fixed with multiple fixing rods 17, and the outer wall of each fixing rod 17 is rotatably fitted with an auxiliary roller 18.

[0039] In this embodiment, the auxiliary roller 18 can be rotated stably by multiple fixed rods 17, thereby driving the woven bag film to move in the water.

[0040] In use, multiple fixed rods 17 can stably rotate the auxiliary roller 18, thereby moving the woven bag film in the water. The cold water frame 1 is filled with cold water, which can quickly cool the extruded woven bag film, thus facilitating the drawing process. The fixed frame 2 can symmetrically fix the bag clamping structure. Controlling the rotation of the main rotating disk 5 can drive the rotation of the threaded rod 3, thereby using the thread to control the two clamping plates 4 to move closer and further apart, thus clamping the woven bag film. The moving woven bag film moves between the two clamping plates 4, which can remove water from the surface of the woven bag film while tightening the woven bag film, thereby making the drawing tension uniform and allowing the cutter to work. When used on woven bag film, it can produce uniform and continuous ribbons. The two connecting rods 8 can fix the fixing strip 7 and the secondary connecting plate 9 together, and at the same time slide stably on the main connecting plate 6. The secondary rotating disk 12 can drive the rotating rod 11 to rotate, and the secondary connecting plate 9 can be moved up and down by using the thread. The drawing knife 10 can act on the surface of the woven bag film to produce uniform and continuous ribbons. The mounting frame 13 can fix multiple fan frames 15, and multiple protective nets 14 can prevent foreign objects from entering the mounting frame 13. When the fan motor 16 is powered on, it can generate wind power, thereby making the water on the drawing surface evaporate quickly.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
