DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] For example, see Figure 1-8 The present invention provides an intelligent wire drawing device for woven bags, comprising a shell 1, a traction roller 2 is rotatably connected to the inner wall of the shell 1, and a tooth hole 3 is provided at the end of the traction roller 2, a slide groove 5 is penetrated through the side wall of the shell 1, and a first stretching roller 6 is slidably connected to the inner wall of the slide groove 5, and a second stretching roller 8 is rotatably connected to the inner wall of the shell 1, two installation grooves 11 are provided on the inner wall of the shell 1, and the bottoms of the two installation grooves 11 are fixedly connected to installation rods 12, a buffer roller 13 is slidably connected between the two installation rods 12, a counterweight block 16 is slidably connected to the outer wall of the installation groove 11, and an extruder 17 is fixedly installed inside the shell 1.

[0033] The inner wall of the tooth hole 3 is provided with an anti-breaking mechanism 4 to prevent the filament from breaking due to excessive pulling force during the wire drawing process.

[0034] A tensioning mechanism 7 is provided at the end of the first stretching roller 6 so as to automatically adjust the tension of the filament during the stretching process when the wire drawing process is performed.

[0035] Furthermore, the anti-breaking mechanism 4 includes a rotating shaft 401, and a first pawl 402 is fixedly installed on the side wall of the rotating shaft 401, the outer wall of the first pawl 402 matches and meshes with the inside of the tooth hole 3, and a second pawl 403 is fixedly installed on the end of the rotating shaft 401 away from the first pawl 402. The outer wall of the outer shell 1 is rotatably connected to a ratchet 404, and the inner wall of the ratchet 404 matches and meshes with the outer wall of the second pawl 403. The tensioning mechanism 7 includes a rotating rod 701, and a convex plate 702 is fixedly connected to the outer wall of the rotating rod 701, and two oblique blocks 703 are rotatably connected to the outer wall of the rotating rod 701, and the outer walls of the two oblique blocks 703 are fixedly connected to the fixed plate 704, and a tension spring 705 is fixedly connected between the two fixed plates 704, and one end of the rotating rod 701 is fixedly connected to a gear 706.

[0036] In this embodiment, first, a corresponding counterweight 16 is installed on the outer wall of the mounting groove 11 according to the tensile strength of the filament, so that the downward pressure of the buffer roller 13 matches the tensile force of the filament. Then, when the wire drawing process is performed, the raw materials are heated and plasticized by the extruder 17, and finally the filaments are produced by extrusion. Then, the filaments extruded by the extruder 17 are wound around the traction roller 2, and the traction roller 2 can pull the filaments so that they can smoothly enter the first stretching roller 6 and the second stretching roller 8. Then, the filaments pass through the surface of the second stretching roller 8, the buffer roller 13 and the first stretching roller 6. Through the cooperation of the buffer roller 13 and the counterweight 16, the filaments are stretched when passing through, thereby achieving the purpose of wire drawing.

[0037] During the wire drawing process, the filament may experience unstable tension. If the tension is too small, the counterweight 16 drives the buffer roller 13 to slide downward along the outer wall of the mounting rod 12, and the filament can be driven downward to make the stretching path of the filament longer. The cooperation between the buffer roller 13 and the counterweight 16 allows the filament to be subjected to matching tension. When the tension is too large, the filament will drive the buffer roller 13 to move upward to shorten the stretching path of the filament. Both ends of the buffer roller 13 are fixedly connected to a connecting rod 14, and one end of the connecting rod 14 is fixedly connected to a rack 15. At the same time, the buffer roller 13 will The rack 15 is driven to move upward synchronously through the connecting rod 14, and the inner wall of the rack 15 matches and meshes with the inner wall of the gear teeth of the ratchet 404. During the movement of the rack 15, the ratchet 404 is driven to rotate, and then the ratchet 404 drives the rotating shaft 401 to rotate synchronously through the second ratchet 403. Since the outer wall of the first ratchet 402 matches and meshes with the inner wall of the tooth hole 3, when the rotating shaft 401 rotates, the traction roller 2 is driven to rotate synchronously through the first ratchet 402, which can increase the unwinding speed of the traction roller 2 and prevent the filament from being unable to withstand the tension and breaking.

[0038] When the pulling force is too large and the connecting rod 14 moves upward for a certain distance, the tension of the filament can be automatically adjusted through the tensioning mechanism 7, wherein the side wall of one of the fixed plates 704 is fixedly connected to the outer wall of the shell 1, and the side wall of the fixed plate 704 is fixedly connected to a connecting plate 707, and the side wall of the other fixed plate 704 is fixedly connected to the end of the first stretching roller 6, and the interior of the connecting plate 707 is slidably connected to a limiting rod 708, and the end of the limiting rod 708 is fixedly connected to a connecting block 709, and the side of the connecting block 709 close to the gear 706 is provided with a convex tooth, and the inner wall of the convex tooth matches and meshes with the inner wall of the gear teeth of the gear 706. The bottom of the connecting plate 707 is fixedly connected with a spring 710, and the end of the spring 710 away from the connecting plate 707 is fixedly connected to the inner wall of the connecting block 709, and the bottom of the connecting block 709 is fixedly connected with a clamping block 711, and the other end of the connecting rod 14 corresponds to the inner wall of the clamping block 711, and then the end of the connecting rod 14 will be engaged with the inner wall of the clamping block 711, and then the limiting rod 708 will be driven by the connecting block 709 to slide upward along the inner wall of the connecting plate 707, and the spring 710 will be compressed at the same time. During the movement of the connecting block 709, the gear 706 will be driven to rotate through the convex teeth, and then the gear 706 The convex plate 702 will be driven to rotate synchronously through the rotating rod 701. During the rotation of the convex plate 702, the inclined surfaces of the inclined blocks 703 on both sides will be squeezed. Then one of the inclined blocks 703 will slide along the outer wall of the rotating rod 701, so that it drives the first stretching roller 6 to slide along the inner wall of the slide groove 5 through the corresponding fixed plate 704. During the movement of the first stretching roller 6, the stretching path of the filament will be changed. When the tension of the filament is unstable, the buffer roller 13 drives the filament to move, and the first stretching roller 6 can drive the filament to move synchronously, so as to realize automatic adjustment of the tension of the filament, thereby being able to Ensure that appropriate tension is maintained during the wire drawing process. When the tension returns to normal, the buffer roller 13 will drive the connecting rod 14 to move downward. When the connecting rod 14 disengages from the block 711, the spring 710 will drive the connecting plate 707 to reset, and then the gear 706 will rotate in the opposite direction, thereby driving the convex plate 702 to disengage from the inclined surface of the inclined block 703 through the rotating rod 701, and then the first stretching roller 6 will be driven to reset and slide through the tension spring 705. When the connecting rod 14 stops driving the rack 15 to move upward, the ratchet 404 will drive the rotating shaft 401 to rotate, so that the unwinding speed of the traction roller 2 returns to normal.

[0039] As described above, when the tension is too large, the filament will drive the buffer roller 13 to move upward, shortening the stretching path of the filament. At the same time, the buffer roller 13 will drive the rack 15 to move upward, so that the ratchet 404 will drive the rotating shaft 401 to rotate through the second ratchet 403, and then the rotating shaft 401 will drive the traction roller 2 to rotate synchronously through the first ratchet 402, so that the unwinding speed of the traction roller 2 is greater than the subsequent winding speed, so that when the tension of the filament is too large, it can avoid the situation that the filament cannot withstand the tension and breaks.

[0040] The tension of the filament can be automatically adjusted through the tensioning mechanism 7, and the block 711 is squeezed by the end of the connecting rod 14, so as to drive the first stretching roller 6 to slide along the inner wall of the slide groove 5, and at the same time, the filament can be driven to move synchronously. During the movement of the first stretching roller 6, the stretching path of the filament will be changed, so that the filament always remains in a straight state, and the tension of the filament can be automatically adjusted, thereby ensuring that the appropriate tension is maintained during the wire drawing process, and the downtime caused by unstable tension can be reduced, thereby ensuring the stable operation of the device during the wire drawing process.

[0041] Embodiment 2: Based on the above embodiment, a spacing mechanism 9 is provided on the outer wall of the second stretching roller 8 so that the stretching path of the filament can be adjusted according to the filament width before the wire drawing process.

[0042] Furthermore, the spacing mechanism 9 includes a spacing plate 901, and a spacing groove 902 is formed through the top of the spacing plate 901, the inner wall of the spacing groove 902 is slidably connected to a sliding rod 903, and the outer wall of the sliding rod 903 is slidably connected to a sliding plate 904, the bottom of the sliding rod 903 is fixedly connected to a first limiting ring 905, and the side wall of the first limiting ring 905 is fixedly connected to a first fixing rod 906, the end of the first fixing rod 906 away from the first limiting ring 905 is slidably connected to a second fixing rod 907, and the end of the second fixing rod 907 away from the first fixing rod 906 is fixedly connected to a second limiting ring 908, the inner wall of the first limiting ring 905 is slidably connected to the outer wall of the second stretching roller 8, and the inner wall of the second fixing rod 907 is slidably connected to the outer wall of the first stretching roller 6.

[0043] In this embodiment, before the wire drawing process, the spacing mechanism 9 can be adjusted according to the width of the filament, the inner wall of the shell 1 is fixedly connected with the card plate 10, and the end of the spacing plate 901 is slidably connected to the outer wall of the card plate 10, and then the spacing plate 901 is pushed to slide along the outer wall of the card plate 10, and at the same time, multiple sliding rods 903 will slide along the corresponding spacing grooves 902, and at the same time, can drive the first limiting ring 905 to slide along the outer wall of the second stretching roller 8, the spacing between the multiple sliding first limiting rings 905 is consistent with the width of the filament, and at the same time, the first fixed rod 906 can drive the second limiting ring 908 to slide along the outer wall of the first stretching roller 6 through the second fixed rod 907, so that the positions of the first limiting ring 905 and the second limiting ring 908 are consistent, and then while stretching the multiple filaments, the stretching path of the multiple filaments can be limited, so that the multiple filaments can remain stable during the stretching process.

[0044] As described above, the spacing mechanism 9 is adjusted according to the width of the filaments, and the multiple sliding rods 903 are pushed along the corresponding spacing grooves 902, and at the same time, the first limiting ring 905 can be driven to slide along the outer wall of the second stretching roller 8. Then, while stretching the multiple filaments, the stretching paths of the multiple filaments can be limited to avoid the situation where the multiple filaments are in contact with each other and entangled with each other, thereby improving the production efficiency and the stability of filament stretching.

[0045] Working principle: During the wire drawing process, the tension of the filament may be unstable. If the tension is too small, the counterweight 16 drives the buffer roller 13 to slide downward along the outer wall of the mounting rod 12, which can drive the filament downward to make the stretching path of the filament longer. The cooperation between the buffer roller 13 and the counterweight 16 allows the filament to be subjected to matching tension. When the tension is too large, the filament will drive the buffer roller 13 to move upward to shorten the stretching path of the filament. At the same time, the buffer roller 13 will drive the rack 15 to move upward synchronously through the connecting rod 14. The inner wall of the rack 15 is matched and meshed with the inner wall of the gear teeth of the ratchet 404. When the rack 15 moves, the ratchet 404 is driven to rotate. Then the ratchet 404 drives the rotating shaft 401 to rotate synchronously through the second ratchet 403. Since the outer wall of the first ratchet 402 is matched and meshed with the inner wall of the tooth hole 3, when the rotating shaft 401 rotates, the traction roller 2 is driven to rotate synchronously through the first ratchet 402, which can increase the unwinding speed of the traction roller 2 and prevent the filament from being unable to withstand the tension and breaking.

[0046] When the pulling force is too large and the connecting rod 14 moves upward for a certain distance, the tension of the filament can be automatically adjusted through the tensioning mechanism 7, and the block 711 is squeezed by the end of the connecting rod 14, and the limit rod 708 is driven by the connecting block 709 to slide upward along the inner wall of the connecting plate 707, and the spring 710 is compressed at the same time. During the movement of the connecting block 709, the gear 706 is driven to rotate through the convex teeth, and then the gear 706 drives the convex plate 702 to rotate synchronously through the rotating rod 701. During the rotation of the convex plate 702, the inclined surfaces of the inclined blocks 703 on both sides are squeezed, and then one of the inclined blocks 703 slides along the outer wall of the rotating rod 701, so that it drives the first stretching roller 6 to slide along the inner wall of the slide groove 5 through the corresponding fixed plate 704. During the movement of the first stretching roller 6, the The stretching path of the filament, when the tension of the filament is unstable, the buffer roller 13 drives the filament to move while the first stretching roller 6 drives the filament to move synchronously, so as to automatically adjust the tension of the filament, thereby ensuring that the appropriate tension is maintained during the wire drawing process. After that, when the tension returns to normal, the buffer roller 13 will drive the connecting rod 14 to move downward. When the connecting rod 14 disengages from the block 711, the spring 710 will drive the connecting plate 707 to reset, and then the gear 706 will rotate in the opposite direction, thereby driving the convex plate 702 to disengage from the inclined surface of the inclined block 703 through the rotating rod 701, and then the first stretching roller 6 will be driven to reset and slide through the tension spring 705. When the connecting rod 14 stops driving the rack 15 to move upward, the ratchet 404 will drive the rotating shaft 401 to rotate, so that the unwinding speed of the traction roller 2 returns to normal.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
