Abstract

This invention relates to the field of plastic processing technology and discloses a guiding structure for plastic filament materials. It solves the problem that in the preparation process of plastic granules, manually guiding high-temperature and fragile molten filaments through a water tank can easily cause them to break, leading to increased operational difficulty, production interruptions, and reduced production efficiency. Through the setup of a wire clamping mechanism and a lead screw slide module, automated guidance of the filament material from the extruder head to the conveying assembly is achieved, eliminating the need for manual operation, reducing labor intensity, and improving production efficiency. Simultaneously, the arc-shaped plate and wire clamping rod can clamp the filament material at equal intervals, and when the tension of the filament material increases, the arc-shaped plate can rotate automatically to buffer, effectively preventing the filament material from breaking due to excessive tension, thus ensuring the continuity and stability of production.

Description

Technical Field

[0001] This invention relates to the field of plastic processing technology, specifically to a guiding structure for plastic filament materials. Background Technology

[0002] In the production of plastic products, raw materials are typically processed into granules to facilitate subsequent processing and molding. In the preparation process of plastic granules, an extruder extrudes molten plastic from the die head, forming filaments. These filaments are then cooled and solidified in a water bath. Finally, the solidified filaments are fed into a pulverizer for further processing into plastic granules. The entire process is continuous, ensuring high efficiency and stability in production.

[0003] However, a technical bottleneck exists in the existing process. After the extruder initially extrudes the molten filaments, they need to be manually guided through a water tank. Because the molten filaments are hot and fragile, they are easily broken during manual guidance. This not only increases the difficulty of operation but also leads to production interruptions and affects efficiency. Therefore, automation and optimization of this step are urgent problems to be solved in current plastic granule raw material processing technology. Summary of the Invention

[0004] The purpose of this invention is to provide a guiding structure for plastic filament materials, which solves the problem that in the preparation process of plastic granules, the high-temperature and fragile filamentous molten material is easily broken when manually guided through the water tank, which increases the difficulty of operation, causes production interruption, and easily affects production efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a guiding structure for plastic processing filament materials, including a water tank, an extruder disposed on one side of the water tank, the extruder head disposed above the water tank, a coolant and multiple guide rollers disposed inside the water tank, and a conveying assembly disposed on the side of the water tank away from the extruder head, the conveying assembly uniformly discharging the cooled filament material from the water tank to one side, and further comprising:

[0006] The guide rail and multiple lead screw slide modules are assembled inside the water tank, and the guide rail path is S-shaped and bypasses the multiple lead screw slide modules;

[0007] A wire clamping mechanism is mounted on one side of a guide rail and is driven to move on one side of the guide rail by a lead screw slide module. The wire clamping mechanism includes an arc-shaped plate, on one side of which a wire clamping rod is movably mounted via a clamping assembly. Guide blocks are provided at both ends of the arc-shaped plate, and the guide blocks are movably mounted on the inner side of the guide rail. Multiple wire-dividing grooves are formed on the surface of the arc-shaped plate, and the arc surface of the wire clamping rod has protrusions corresponding to the multiple wire-dividing grooves. The wire clamping rod is driven by the clamping assembly to be tightly attached to the surface of the arc-shaped plate.

[0008] As a further description of the above technical solution: the clamping assembly includes a Z-shaped rod, the middle part of which is rotatably mounted on the arc surface of the arc plate via a mounting base, one end of the clamping rod is fixedly connected to one end of the Z-shaped rod, and a second torsion spring is provided on the inner side of the mounting base to elastically drive the Z-shaped rod to rotate. The second torsion spring drives the clamping rod to approach the arc surface of the arc plate through the Z-shaped rod.

[0009] As a further description of the above technical solution: a stop block is fixedly mounted on one end of the guide rail near the machine head. The stop block is pressed against one end of the Z-shaped rod, causing the Z-shaped rod to rotate against the elastic force of the second torsion spring, supporting the wire clamping rod on one side of the arc plate. An opening is formed between the arc plate and the wire clamping rod, and the opening is located below the machine head.

[0010] As a further description of the above technical solution: the guide rail and the lead screw slide module are provided on both sides of the inner side of the water tank. The upper surface of the movable block of the lead screw slide module is connected to a pull rope, and the other end of the pull rope is fixedly connected to the lower surface of the guide block.

[0011] As a further description of the above technical solution: a synchronous shaft is provided on one side of each of the two lead screw slide modules. The synchronous shaft is connected to the lead screw of the two lead screw slide modules through a crown gear transmission structure. One end of the synchronous shaft extends through to the outside of the water tank. A motor for driving the synchronous shaft to rotate is installed on the outside of the water tank.

[0012] As a further description of the above technical solution: the conveying assembly includes a second guide roller and a pressure roller. The second guide roller and the pressure roller are rotatably mounted on the upper side of the water tank via an assembly frame. A second motor for driving the pressure roller to rotate is provided on one side of the assembly frame.

[0013] The second motor drives the rotation of the pressure roller, which discharges the solidified filamentous material from one side of the water tank. The discharge speed of the filamentous material through the second guide roller and the pressure roller is consistent with the speed at which the filamentous material is extruded from the die head.

[0014] As a further description of the above technical solution: a side plate is connected to one side of the arc-shaped plate, and the guide block is rotatably connected to the side plate through a rotating column on one side. A torsion spring is also provided on the surface of the rotating column.

[0015] As a further description of the above technical solution: the end of the Z-shaped rod away from the clamping rod is fixedly connected to a second pull rope, and one end of the second pull rope is fixedly connected to the surface of the guide block;

[0016] One side of the assembly frame is equipped with an electric cylinder for pushing the side plate.

[0017] As a further description of the above technical solution: the inner diameter of the arc-shaped plate is larger than the inner diameter of the guide roller.

[0018] As a further description of the above technical solution: The arc-shaped plate has an inclined surface on the side near the pressure roller.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. The wire clamping mechanism and lead screw slide module enable automated guidance of filamentous materials from the extruder head to the conveying assembly, eliminating the need for manual operation, reducing labor intensity, and improving production efficiency.

[0021] 2. The curved plate and clamping rod can clamp the filamentous material at equal intervals, and when the tension of the filamentous material increases, the curved plate can rotate on its own to buffer the movement, effectively preventing the filamentous material from breaking due to excessive tension, thus ensuring the continuity and stability of production.

[0022] 3. The dividing grooves on the surface of the arc plate correspond one-to-one with the filamentous materials, which can separate multiple filamentous materials at equal intervals and arrange them neatly on the guide roller, avoiding the entanglement between multiple filamentous materials and improving product quality.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0034] A plastic processing filament material guiding structure, combined with Figures 1 to 8 The device includes a water tank 20. An extruder is located on one side of the water tank 20, with the extruder head 10 positioned above the water tank 20. The water tank 20 contains coolant, typically cold water, and also includes multiple guide rollers 21. A conveying assembly 25 is located on the side of the water tank 20 away from the die head 10, used to uniformly discharge the cooled filamentous material. After being extruded from the die head 10, the filamentous material hangs vertically downwards into the water tank 20. Multiple filaments must sequentially pass over the multiple guide rollers 21 before being discharged by the conveying assembly 25.

[0035] The conveying assembly 25 includes a guide roller 251 and a pressure roller 252, which are rotatably mounted on the upper side of the water tank 20 via a mounting frame 253. A motor 255 is located on one side of the mounting frame 253 to drive the pressure roller 252 to rotate, thereby discharging the cured filamentous material from one side. The speed at which the filamentous material is discharged through the guide roller 251 and pressure roller 252 is consistent with the speed at which the die head 10 extrudes the filamentous material. The conveying speed of the conveying assembly 25 is matched with the extrusion speed of the die head 10 to avoid tension between the filamentous material and the die head 10. The filamentous material discharged from the die head 10 is only subject to gravity during its downward movement.

[0036] Combination Figures 2 to 8 To simplify the operation of routing filamentous material around multiple guide rollers 21 and docking with the conveying assembly 25, the following configuration is made inside the water tank 20:

[0037] The inner side of the water tank 20 is equipped with a guide rail 22 and multiple lead screw slide modules 23. The guide rail 22 has an S-shaped path that bypasses the multiple lead screw slide modules 23. The wire clamping mechanism 30 is mounted on one side of the guide rail 22 and is driven by the lead screw slide modules 23 to move on one side of the guide rail 22. The wire clamping mechanism 30 includes an arc-shaped plate 31, and a wire clamping rod 32 is movably mounted on one side of the arc-shaped plate 31 via a clamping assembly 34. Guide blocks 33 are provided at both ends of the arc-shaped plate 31, and the guide blocks 33 are movably mounted on the inner side of the guide rail 22. Multiple wire-dividing grooves 311 are formed on the surface of the arc-shaped plate 31, corresponding one-to-one with the multiple filamentous materials extruded by the die head 10. The arc surface of the wire clamping rod 32 has protrusions corresponding to the multiple wire-dividing grooves 311, and is driven by the clamping assembly 34 to be tightly attached to the surface of the arc-shaped plate 31.

[0038] Specifically, the clamping area between the arc-shaped plate 31 and the clamping rod 32 is located below the die head 10. When the arc-shaped plate 31 and the clamping rod 32 are below the die head 10, they are separated. The filamentous material extruded from the die head 10 hangs down naturally and falls into the water tank 20. The cold water in the water tank 20 cools and solidifies the filamentous material, which then enters the area between the arc-shaped plate 31 and the clamping rod 32. Subsequently, the lead screw slide module 23 drives the arc-shaped plate 31 to pass through multiple guide rollers 21 along the preset path of the guide rail 22. Since the multiple dividing grooves 311 on the surface of the arc-shaped plate 31 correspond to the positions of the filamentous material, when the clamping rod 32 cooperates with the arc-shaped plate 31 to clamp the filamentous material, the multiple dividing grooves 311 can separate multiple filamentous materials at equal intervals.

[0039] Next, the lead screw slide module 23 continues to drive the arc plate 31. Under the guidance of the guide rail 22, the filament material held by the arc plate 31 and the wire clamping rod 32 passes around multiple guide rollers 21 in sequence and finally moves to one side of the conveying component 25, where one end of the filament material is connected to the conveying component 25 to complete the threading process.

[0040] It is worth mentioning that the arc-shaped plate 31 and the clamping rod 32 can clamp the filamentous material at equal intervals, so that the filamentous material is automatically in the threading state along with the clamping mechanism 30. Multiple filamentous materials can be automatically aligned into the grooves on the surface of the guide roller 21 and neatly arranged on the guide roller 21, avoiding the phenomenon of multiple filamentous materials tangling together.

[0041] Combination Figure 2 , Figure 3 and Figure 7 The structure and working principle of the crimping assembly 34 are as follows:

[0042] The clamping assembly 34 includes a Z-shaped rod 341, the middle part of which is rotatably mounted on the arc surface of the arc plate 31 via a mounting base 342. One end of the clamping rod 32 is fixedly connected to one end of the Z-shaped rod 341. A torsion spring 2 is provided inside the mounting base 342, which elastically drives the Z-shaped rod 341 to rotate, thereby causing the clamping rod 32 to come close to the arc surface of the arc plate 31 via the Z-shaped rod 341.

[0043] A stop 24 is fixedly mounted on one end of the guide rail 22 near the head 10. When the arc plate 31 moves to the position of the stop 24, the stop 24 presses against one end of the Z-shaped rod 341. At this time, the Z-shaped rod 341 rotates against the elastic force of the torsion spring 2, supporting the wire clamping rod 32 on one side of the arc plate 31, so that an opening is formed between the arc plate 31 and the wire clamping rod 32, which is located directly below the head 10.

[0044] The specific work process is as follows:

[0045] After the filamentous material extruded from the die head 10 is initially cooled and solidified by the cold water in the water tank 20, it automatically falls into the opening between the curved plate 31 and the clamping rod 32. Subsequently, the lead screw slide module 23 drives the curved plate 31 to move along the guide rail 22. Figure 3 When one end of the Z-shaped rod 341 moves away from the stop block 24, the elastic force of the torsion spring 2 causes the Z-shaped rod 341 to rotate, thereby pressing the wire clamping rod 32 against the outer surface of the arc plate 31. In this way, one end of the filamentous material is firmly clamped on the arc surface of the arc plate 31, providing stable initial conditions for subsequent guiding and conveying operations.

[0046] Combination Figures 2 to 5 In this plastic processing filament material guiding structure, guide rail 22 and lead screw slide module 23 are provided on both sides inside the water tank 20. A pull rope 232 is connected to the upper surface of the movable block 231 of the lead screw slide module 23, and the other end of the pull rope 232 is fixedly connected to the lower surface of the guide block 33.

[0047] A synchronous shaft 233 is provided on one side of each of the two lead screw slide modules 23. The synchronous shaft 233 is connected to the lead screws of the two lead screw slide modules 23 through a crown gear transmission structure. One end of the synchronous shaft 233 extends to the outside of the water tank 20, and a motor for driving the synchronous shaft 233 to rotate is mounted on the outside of the water tank 20.

[0048] The specific construction of the crown gear transmission structure is as follows: a driven crown gear is fixedly connected to one end of the lead screw of each lead screw slide module 23, while a driving crown gear that meshes with the driven crown gear is fixedly mounted on the surface of the synchronous shaft 233.

[0049] The specific working principle is as follows:

[0050] When the motor controls the synchronous shaft 233 to rotate, the synchronous shaft 233 synchronously drives the lead screws on the two lead screw slide modules 23 to rotate through the crown gear transmission structure. The rotation of the lead screws further drives the movable blocks 231 on the two lead screw slide modules 23 to move synchronously. The movement of the movable blocks 231 pulls the guide block 33 to move inside the guide rail 22 through the pull rope 232 connected to the upper side. In this way, the arc plate 31 can be precisely controlled to move along the preset path of the guide rail 22.

[0051] Combination Figure 7 and Figure 8 A side plate 312 is connected to one side of the arc-shaped plate 31. A guide block 33 is rotatably connected to the side plate 312 via a rotating column 331 on one side. A torsion spring 332 is provided on the surface of the rotating column 331. Under normal conditions, the arc-shaped plate 31 is movably mounted on one side of the guide block 33 by the elastic limitation of the torsion spring 332. This design allows the arc-shaped plate 31 to rotate and buffer itself if the tension of the filamentous material increases during the movement of the arc-shaped plate 31 along a preset path, thereby reducing the tension on the filamentous material and further preventing the filamentous material from breaking due to excessive tension.

[0052] Combination Figures 6 to 8 One end of the Z-shaped rod 341 away from the wire clamping rod 32 is fixedly connected to a second pull rope 343, and the other end of the second pull rope 343 is fixedly connected to the surface of the guide block 33. An electric cylinder 254 for pushing the side plate 312 is provided on one side of the assembly frame 253. Furthermore, the inner diameter of the arc-shaped plate 31 is slightly larger than the inner diameter of the second wire guide roller 251, and the side of the arc-shaped plate 31 near the pressure roller 252 has an inclined surface 313, with the wire clamping rod 32 clamped on one side of the inclined surface 313.

[0053] The specific work process is as follows:

[0054] Combination Figure 6 When the arc-shaped plate 31 moves along the path of the guide rail 22 to one side of the guide roller 251, it can be fitted onto the outer surface of the guide roller 251. At this time, one end of the filamentous material clamped between the clamping rod 32 and the inclined surface 313 can be automatically inserted into the conveying working area between the guide roller 251 and the pressure roller 252. Subsequently, the side plate 312 is pushed by the electric cylinder 254, causing the arc-shaped plate 31 to rotate counterclockwise. At the same time, the clamping assembly 34 rotates with the arc-shaped plate 31, and the Z-shaped rod 341 rotates under the pull of the second pull rope 343, causing the clamping rod 32 to move away from the surface of the arc-shaped plate 31. In this way, the arc-shaped plate 31 and the clamping rod 32 disconnect from the clamping effect on the filamentous material, allowing the filamentous material to be smoothly conveyed by the conveying assembly 25.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
