[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] like Figures 1 to 5 As shown, this embodiment proposes a precision-controlled wire drawing device for woven bag production, comprising a plastic extruder main body 1, a support frame 2 fixedly connected to the discharge end of the plastic extruder main body 1, an assembly frame 3 fixedly connected to one end of the support frame 2, a polished rod 4 vertically rotatably connected to the inner side of the assembly frame 3, a threaded section 5 is provided at the top and bottom ends of the outer side of the polished rod 4, and the thread rotation directions of the two threaded sections 5 are opposite, and the outer sides of the two threaded sections 5 are threadedly connected to an adjusting frame 6, one end of the adjusting frame 6 is rotatably connected to a central shaft 7, and a detachable forming roller 8 is assembled at one end of the central shaft 7 away from the adjusting frame 6, and a transmission assembly 9 is provided on the inner side of the assembly frame 3, which is used to simultaneously drive the two forming rollers 8 to rotate in opposite directions;

[0027] Here, the plastic extruder body 1 is a device for extruding molten plastic through a nozzle, and mainly includes a heating system for heating the molten plastic to a desired temperature, an injection pump for transporting the molten plastic from the heating system to the nozzle, and an injection valve for controlling the flow of plastic flowing from the injection pump. The working principle is to extract the molten plastic from the heating system and then pass it through a narrow nozzle. In this process, the plastic is rapidly compressed and forced through the narrow slit to form the desired plastic strip;

[0028] In detail, the ends of the central shaft 7 and the forming roller 8 close to each other are fixedly connected with a flange 21, and the central shaft 7 and the forming roller 8 are connected through the flange 21. The setting of the flange 21 can ensure the stability of the connection between the central shaft 7 and the forming roller 8, and can also conveniently remove and replace the forming roller 8, thereby meeting the production of woven bag wire drawing of different specifications;

[0029] Preferably, the bottom end of the assembly frame 3 is rotatably connected to a force-bearing handle, and one end of the force-bearing handle located on the inner side of the assembly frame 3 is also fixedly connected to the polished rod 4. By utilizing the arrangement of the force-bearing handle, when the force-bearing handle is rotated, the polished rod 4 can be driven to rotate accordingly, thereby effectively improving the transmission efficiency of the polished rod 4.

[0030] Here, the outer sides of both ends of the forming roller 8 are fixedly connected with a blocking disk, and the blocking disk is coated with a non-stick layer. By setting the blocking disk, the width direction of the woven bag drawing can be restricted, making the size of the woven bag drawing more controllable;

[0031] The transmission assembly 9 includes a transmission shaft 10, a transmission motor 11, a linkage shaft 12, a transmission bevel gear 13 and a matching bevel gear 14. The inner side of the assembly frame 3 is also vertically rotatably connected to the transmission shaft 10, and the top of the assembly frame 3 is fixedly connected to the transmission motor 11, and the output end of the transmission motor 11 is fixedly connected to the transmission shaft 10. The middle parts of the two adjustment frames 6 are rotatably connected to the linkage shaft 12, and the two linkage shafts 12 are slidably connected to the outside of the transmission shaft 10. The bottom end of the linkage shaft 12 is fixedly connected to the transmission bevel gear 13, and the end of the central shaft 7 close to the linkage shaft 12 is fixedly connected to the matching bevel gear 14, and the matching bevel gear 14 is meshed with the transmission bevel gear 13. A wind-making component is also provided on the adjustment frame 6, which is used to accelerate the airflow at the forming roller 8;

[0032] Furthermore, a guide bar is fixedly connected to the outside of the transmission shaft 10, and a limit groove is provided inside the linkage shaft 12, and the guide bar is also slidably connected to the inside of the limit groove. The structural cooperation between the guide bar and the limit groove allows the linkage shaft 12 to slide along the transmission shaft 10. When the transmission shaft 10 rotates, the linkage shaft 12 can also be driven to rotate accordingly through the setting of the guide bar.

[0033] Example 2

[0034] like Figures 1 to 5 As shown, based on the same concept as the above embodiment 1, this embodiment also proposes a wind-generating component;

[0035] In this embodiment, the wind-making assembly includes an extension frame 15, a wind-making shaft 16, a wind-making disk 17 and a synchronous wheel A18. The end of the adjustment frame 6 away from the transmission bevel gear 13 is fixedly connected to the extension frame 15, the top end of the extension frame 15 is fixedly connected to the wind-making shaft 16, the bottom end of the wind-making shaft 16 is fixedly connected to the wind-making disk 17, the top end of the outer side of the linkage shaft 12 is fixedly connected to the synchronous wheel A18, the middle part of the wind-making shaft 16 is fixedly connected to the synchronous wheel B19, and the synchronous wheel B19 and the synchronous wheel A18 are connected by a synchronous belt 20;

[0036] Furthermore, a plurality of fan blades are fixedly connected to the outer side of the air-generating disk 17, and the fan blades are arranged at an angle. By utilizing the arrangement of the fan blades, airflow can be generated during the rotation of the air-generating disk 17, thereby assisting in cooling the woven bag wire drawing and shaping it.

[0037] A specific application of the above two embodiments is to extrude woven bag wire through the plastic extruder body 1, and pass the wire through the two forming rollers 8, then start the transmission motor 11 to drive the transmission shaft 10 to rotate, cooperate with the connection between the linkage shaft 12 and the transmission shaft 10, so that the linkage shaft 12 can rotate with the transmission shaft 10, and dial the matching bevel gear 14 through the transmission bevel gear 13, and then drive the forming roller 8 to rotate through the center shaft 7. Since the wire is located between the two forming rollers 8, during the wire transmission process, the gap between the two forming rollers 8 can be used to extrude the wire, so that the wire is formed between the two forming rollers 8;

[0038] In the process of the linkage shaft 12 rotating, the power of the linkage shaft 12 can be transmitted to the wind-generating shaft 16 through the synchronous belt 20, so that the wind-generating shaft 16 drives the wind-generating disk 17 to rotate, thereby accelerating the gas flow at the forming roller 8, thereby assisting the wire drawing cooling and enabling the wire drawing to be shaped faster;

[0039] When the wire drawing thickness changes, the polished rod 4 is rotated, and the two threaded segments 5 with opposite thread rotation directions are arranged, which can drive the two adjustment frames 6 to move toward each other on the outside of the two threaded segments 5, thereby changing the distance between the two forming rollers 8, meeting the production needs of wire drawing of different specifications, and combining with the characteristics of the threaded segments 5, the spacing adjustment of the forming rollers 8 can be more precisely controlled, thereby ensuring the quality of the wire drawing;

[0040] When the forming roller 8 does not meet the production requirements of wire drawing, the forming roller 8 can be removed from the central shaft 7 and replaced.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
