[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] Example 1, please refer to Figures 1-4 A tension-adjustable plastic woven bag raw material drawing machine includes a drawing machine body 100, a feed inlet 200 on the side of the drawing machine body 100, a movable seat 300 slidably connected inside the drawing machine body 100, a drawing roller 400 driven by a motor mounted on the side of the movable seat 300, a take-up roller 500 mounted inside the drawing machine body 100, a cold air input pipe 600 mounted on the top of the drawing machine body 100, and a through rotating sleeve 701 rotatably connected inside the drawing machine body 100. A pressing block 703 is connected to the top of the rotating sleeve 701 via a spring 702. The operator first presses the pressing block 703 with one hand, and then rotates the rotating sleeve 701.

[0023] A pressing cone 704 is fixedly connected to the bottom of the pressing block 703. When the pressing block 703 is pressed, it can compress the spring 702 and move downward. The pressing block 703 in the downward moving state can drive the pressing cone 704 fixedly connected to it to move synchronously.

[0024] A rotating disk 705 with a limiting groove is fixedly connected to the outer side of the rotating sleeve 701. An extrusion block 707 is connected to the inner wall of the rotating disk 705 via a second spring 706. The extrusion block 707 is located on the side of the extrusion cone 704 and is in contact with it. When the extrusion cone 704 moves, it drives the extrusion block 707 to move, causing the extrusion block 707 to compress the second spring 706 and move laterally.

[0025] A fixing plate 708 is fixedly connected to the top of the wire drawing machine body 100. A limiting rod 710 is connected to the side of the fixing plate 708 via a spring 709. There are two springs 709, which are symmetrically distributed about the limiting rod 710. When the extrusion block 707 compresses the spring 706 and moves to the side, the limiting rod 710 is pushed out of the limiting groove on the rotating disk 705. The limiting rod 710 then stretches the spring 709 and moves away from the fixing plate 708. In this way, the limiting rod 710 is released from its restriction on the rotating disk 705, and then the rotating sleeve 701 can be rotated.

[0026] A lead screw 711 is fixedly connected to the bottom of the rotating sleeve 701. The movable seat 300 is located outside the lead screw 711, and the movable seat 300 and the lead screw 711 are connected by a thread. When the rotating sleeve 701 rotates, it drives the lead screw 711 fixedly connected to it to rotate. The movable seat 300, which is threaded to the outside of the lead screw 711, is simultaneously restricted by the wire drawing machine body 100, which is slidably connected to it. As the lead screw 711 rotates, it drives the movable seat 300 to move upward, and the wire drawing roller 400 mounted on the movable seat 300 moves synchronously. After the wire drawing roller 400 is moved to the designated position, the rotating sleeve 701 and the pressing block 703 are released, which can re-restrain the rotating disk 705 and the rotating sleeve 701. Subsequently, the raw material to be drawn is fed into the main body 100 of the drawing machine through the feed inlet 200, and the drawing roller 400 performs the corresponding drawing operation. Then, the formed raw material is wound up by the take-up roller 500. In this way, the drawing roller 400 can be moved quickly in the vertical direction, allowing the device to quickly perform drawing operations on woven plastic bags that require different tensions, thus improving the drawing efficiency of the device.

[0027] In practical use, the operator first presses the pressing block 703 with one hand, then rotates the rotating sleeve 701. The pressed pressing block 703 compresses the spring 702 and moves downwards. This downward movement causes the pressing block 703 to move synchronously with the extrusion cone 704, which is fixedly connected to it. During this movement, the extrusion cone 704 moves the extrusion block 707, which in turn compresses the spring 706 and moves laterally, pushing the limiting rod 710 out of the limiting groove on the rotating disk 705. The limiting rod 710 then stretches the spring 709 and moves away from the fixed plate 708, thus removing the restriction of the limiting rod 710 on the rotating disk 705. Only then can the rotating sleeve 701 be rotated. The rotating sleeve 701 then drives the screw 711, which is fixedly connected to it, to rotate. The movable seat 30, threaded onto the outside of the screw 711... Simultaneously restricted by the wire drawing machine body 100 slidably connected to it, the lead screw 711 drives the moving seat 300 to move upward during rotation, and the wire drawing roller 400 mounted on the moving seat 300 moves synchronously. After the wire drawing roller 400 is moved to the designated position, the rotating sleeve 701 and the pressing block 703 are released. The pressing block 703 loses its restriction and can be reset under the action of spring 1 702. The extrusion cone 704 is reset accordingly. The extrusion block 707 loses the restriction of the extrusion cone 704 and can be reset under the action of spring 2 706. The limiting rod 710 loses the restriction of the extrusion block 707 and can be reset under the action of spring 3 709, re-restricting the rotating disk 705 and the rotating sleeve 701. Subsequently, the raw material to be drawn is fed into the wire drawing machine body 100 through the feed port 200, and the wire drawing operation is performed by the wire drawing roller 400. Then, the formed raw material is wound up by the winding roller 500.

[0028] Example 2, please refer to Figures 3-6 Based on Embodiment 1, the drawing machine body 100 is internally equipped with a pressing assembly 800, which includes a threaded block 801 fixed to the outside of the output shaft of the drawing roller 400. When the drawing roller 400 rotates to perform the drawing operation, the rotating drawing roller 400 can drive the threaded block 801 mounted on its output shaft to rotate.

[0029] A sliding block 802 is slidably connected to the side of the threaded block 801. When the threaded block 801 rotates, the sliding block 802 mounted on the threaded block 801 is simultaneously restricted by the wire drawing machine body 100 which is slidably connected to it via a sliding rod 803, so that the sliding block 802 slowly moves to the side during the rotation of the threaded block 801.

[0030] A sliding rod 803 is slidably connected to the inner wall of the wire drawing machine body 100. The top of the sliding rod 803 is connected to a moving rod 805 via a spring 804. When the sliding block 802 moves slowly to the side, it can drive the moving rod 805, which is fixedly connected to it, to move to the side as well.

[0031] The movable rod 805 is located on the side of the sliding block 802, and the movable rod 805 and the sliding block 802 are fixed. When the wire drawing roller 400 moves upward, it can drive the threaded block 801 mounted on the output shaft of the wire drawing roller 400 to move upward together. The threaded block 801 can then drive the movable rod 805 to move upward together through the sliding block 802. The movable rod 805, in the moving state, can stretch the spring 804 and move upward.

[0032] When the moving rod 805 moves to the side, it can drive the pressing plate 807, which is fixedly connected to it, to move. The pressing plate 807 compresses the spring 806 and moves away from the take-up roller 500, so as to stably press the material that gradually thickens on the take-up roller 500, improve the pressing effect of the device, and make the device more stable in use.

[0033] The inner wall of the wire drawing machine body 100 is connected to a pressing plate 807 via a spring 806. A moving rod 808 is fixedly connected to the side of the pressing plate 807. There are two springs 806, which are symmetrically distributed about the moving rod 808. When the moving rod 805 moves upward, it moves to the position of the moving rod 808 and comes into contact with it.

[0034] In practical use, when the drawing roller 400 moves upward, it drives the threaded block 801 mounted on the output shaft of the drawing roller 400 to move upward as well. The threaded block 801 then drives the moving rod 805 to move upward together via the sliding block 802. The moving rod 805, in the moving state, stretches the spring 804 and moves upward, until it reaches and contacts the moving rod 808. When the drawing roller 400 rotates to perform the drawing operation, the rotating drawing roller 400 drives the threaded block 801 mounted on its output shaft to rotate. The sliding block 802, which is mounted on the threaded block 801, is simultaneously restricted by the wire drawing machine body 100, which is slidably connected to it via the sliding rod 803. As the threaded block 801 rotates, the sliding block 802 slowly moves to the side. The sliding block 802 in the moving state can drive the moving rod 805, which is fixedly connected to it, to move to the side. This causes the moving rod 805 to drive the pressing plate 807, which is fixedly connected to it, to move. The pressing plate 807 compresses the spring 806 and moves away from the take-up roller 500, thus stabilizing the material that gradually thickens on the take-up roller 500.

[0035] Example 3, please refer to Figures 5-8 Based on Embodiment 1 or Embodiment 2, the drawing machine body 100 is provided with a flow guiding assembly 900 inside, which includes a rotating block 901 fixed to the outside of the output shaft of the drawing roller 400. When the drawing roller 400 moves upward and rotates, the rotating block 901 mounted on the outside of the output shaft of the drawing roller 400 rotates accordingly.

[0036] A fixed plate 902 is fixedly connected inside the main body 100 of the wire drawing machine. A wedge block 904 is connected to the side of the fixed plate 902 via a spring 903. A force-bearing rod 905 is fixedly connected to the side of the wedge block 904. When the rotating block 901 rotates to the force-bearing rod 905, the rotating block 901 can squeeze the force-bearing rod 905. The squeezed force-bearing rod 905 then moves, and the moving force-bearing rod 905 drives the wedge block 904 fixedly connected to it to compress the spring 903 and move closer to the fixed plate 902.

[0037] Inside the wire drawing machine body 100, a shaped block 907 is connected via a spring 7 906. The shaped blocks 907 are in contact with each other on the side of the inclined block 1 904, and are in contact with each other. Inside the wire drawing machine body 100, a torsion spring rod 908 with an internal torsion spring is rotatably connected. A guide plate 909 is fixedly connected to the bottom of the torsion spring rod 908, located on the side of the shaped block 907, and is in contact with each other. When the inclined block 1 904 presses against the shaped block 907 during its movement, the pressed shaped block 907 stretches the spring 7 906 and moves to the side. The moving shaped block 907 then presses against the guide plate 909, thereby causing the guide plate 909 and the torsion spring rod 908 to rotate at a certain angle. When the rotating block 901 moves away from the force-bearing rod 905 as it rotates, the guide plate 909 can be reset under the action of the torsion spring inside the torsion spring rod 908. In this way, the guide plate 909 can reciprocate at a certain angle, guiding the cold air in the cold air input pipe 600 to various positions between the drawing roller 400 and the take-up roller 500, improving the cold air efficiency of the device, and further improving the drawing efficiency of the device.

[0038] In practical use, when the drawing roller 400 moves upward and rotates, the rotating block 901 mounted on the outside of the output shaft of the drawing roller 400 rotates accordingly. When the rotating block 901 rotates to the force rod 905, it presses against the force rod 905. The pressed force rod 905 then moves, causing the moving force rod 905 to compress the inclined block 904 and the spring 903, moving it closer to the fixed plate 902. During this movement, the inclined block 904 presses against the shaped block 907, causing the pressed shaped block 907 to stretch the spring 906 and move to the side. 907 can squeeze the guide plate 909, thereby driving the guide plate 909 and the torsion spring rod 908 to rotate at a certain angle; when the rotating block 901 moves away from the force rod 905 as it rotates, the force rod 905 loses its restraint and can be reset under the action of the spring six 903, the inclined block one 904 is reset accordingly, the irregular block 907 loses the restraint of the inclined block one 904 and can be reset under the action of the spring seven 906, the guide plate 909 loses the restraint of the irregular block 907 and can be reset under the action of the torsion spring inside the torsion spring rod 908; in this way, the guide plate 909 can reciprocate at a certain angle, guiding the cold air in the cold air input pipe 600 to various positions between the drawing roller 400 and the take-up roller 500.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
