Description

Technical Field

[0001] This utility model relates to the field of molding device technology, specifically to a foam insulation layer molding device for a vehicle-mounted single-pair Ethernet cable. Background Technology

[0002] The foamed insulation layer of a vehicle-mounted single-pair Ethernet cable is an insulation layer made of foamed material. Through a foaming process, a porous structure is formed, resulting in a low dielectric constant, thereby reducing signal transmission delay and loss. This insulation layer not only provides good electrical insulation performance but also reduces the weight of the cable to a certain extent. In addition, the foamed insulation layer also has a certain mechanical protection function, which can enhance the flexibility and bending resistance of the cable. The foamed insulation layer molding device for vehicle-mounted single-pair Ethernet cables is a device used to manufacture cable insulation layers. It processes the insulating material into an insulation layer with a foamed structure through a specific process. The foam insulation layer forming device for vehicle-mounted single-pair Ethernet cables is mainly achieved through extrusion molding process, combined with physical or chemical foaming technology. During the extrusion process, the foaming material is heated to a molten state and then conveyed to the forming die through the extruder screw. Physical foaming forms bubble nuclei by injecting gas under high pressure, while chemical foaming generates gas by adding chemical foaming agents. After the molten material is formed in the die, it is quickly cooled and shaped by a cooling device to form a uniform foam structure. When the raw material enters the extruder, the polypropylene granules are solid particles before entering the extruder. Agglomeration between the particles leads to uneven feeding. This uneven feeding makes the feed rate of the extruder unstable, which in turn affects the extrusion speed and the uniformity of the foamed layer. Although the vibration method in traditional technology can improve the uniformity of feeding, when it is applied to the foamed insulation layer molding device, where the feed box is integrated with the extruder, especially in the part close to the extruder, the vibration may cause mechanical damage to the extruder, aggravate equipment wear, and affect the stable operation and molding accuracy of the extruder. Therefore, to address the above problems, a foamed insulation layer molding device for vehicle-mounted single-pair Ethernet cables is proposed. Utility Model Content

[0016] Please see Figures 1-6 This utility model provides a technical solution: A foam insulation layer molding device for a vehicle-mounted single-pair Ethernet cable includes an extruder 1. A material box assembly 2 is fixedly connected to the upper end of the extruder 1. A drive assembly 3 is installed inside the material box assembly 2. The material box assembly 2 includes a cylindrical box 21. A storage box 22 is fixedly connected to the top of the cylindrical box 21. A fixing column 24 is fixedly connected to the inner side of the cylindrical box 21 near the right end. A toothed column 25 is fixedly connected to the outer side of the fixing column 24. The drive assembly 3 includes a drive motor 31. A column disk 32 is fixedly connected to the end of the main shaft of the drive motor 31. A material collection groove 33 is opened near the outer side of the column disk 32. A central groove 34 and a sliding hole 35 are opened inside the column disk 32. A sliding column 36 is slidably connected inside the sliding hole 35. A vibrating plate 37 is fixedly connected to the outer side of the sliding column 36. A pressure plate 38 is fixedly connected to one end of the sliding column 36. A helical toothed block 39 is fixedly connected to the end of the sliding column 36 away from the pressure plate 38.

[0017] As a further implementation of this solution, a cylindrical groove 23 is provided on the inner side of the cylindrical box 21, and a discharge port 26 is provided on the inner side of the cylindrical box 21 near the lower end. The inner side of the storage box 22, the cylindrical groove 23 and the discharge port 26 are connected. The bottom end of the cylindrical box 21 is fixedly connected to the extruder 1. The toothed column 25 is set inside the discharge port 26. Through the above arrangement, this connected design ensures the smoothness of material transmission and reduces the risk of blockage during material transmission. At the same time, the fixed connection between the bottom end of the cylindrical box 21 and the extruder 1 enhances the structural stability of the device, while the toothed column 25 set inside the discharge port 26 provides mechanical support for the stable transmission of material. As a further implementation of this solution, the left end of the cylindrical box 21 is fixedly connected to the housing of the drive motor 31, and a through hole is opened at the left end of the cylindrical box 21. Through the above setting, the cylindrical plate 32 can be controlled to rotate inside the cylindrical groove 23 to achieve the effect of loading and unloading. As a further implementation of this solution, a central groove 34 is provided on the inner side of the column plate 32, and the toothed column 25 is embedded in the center groove 34. The cylindrical groove 23 is cylindrical in shape and is clearance-fitted with the column plate 32. Through the above settings, this embedded installation method not only improves the structural strength of the device, but also reduces vibration during operation and extends the service life of the equipment. At the same time, it ensures the uniformity and stability of the material during the transmission process. This design improves the uniformity of feeding, thereby ensuring the uniformity of the foamed layer. As a further implementation of this solution, the tablet 38 is located inside the collection trough 33, the vibrating plate 37 is in clearance fit with the inner side of the collection trough 33, the inclined tooth block 39 meshes with the outer side of the tooth column 25, and the vibrating plate 37 is magnetically attracted to the column disk 32. Through the above settings, a highly efficient vibration and crushing mechanism is formed, which not only improves the uniformity of the material, but also effectively deals with the problem of particle agglomeration, ensures a stable feed amount, and thus improves the molding quality of the foamed layer.

[0018] Workflow: During feeding, polypropylene granules are placed inside the storage bin 22. The drive motor 31 is started, driving the column disk 32 to rotate. The column disk 32 drives the internal structure to rotate simultaneously. When the sliding column 36, vibrating plate 37, and helical tooth block 39 rotate simultaneously, the helical tooth block 39 meshes with the outer side of the toothed column 25. The part of the helical tooth block 39 near the toothed column 25 has a sloping structure. Thus, through the compression of the helical tooth block 39 by the toothed column 25, the helical tooth block 39 drives the sliding column 36, vibrating plate 37, and pressing plate 38 to move simultaneously. The vibrating plate 37 and pressing plate 38 move inside the collection trough 33. At the same time, the end of the vibrating plate 37 near the helical tooth block 39 is magnetically attracted to the column disk 32, which serves to reset the vibrating plate 37. At this time, the sliding column 36, vibrating plate 37, pressing plate 38, and helical tooth block 39 will create a vibration effect. When the collection trough 33 is aligned with the lower end of the storage bin 22, the raw material inside the storage bin 22 will enter the collection trough. Inside the material collection trough 33, the material is squeezed and crushed by the vibration of the pressing plate 38. At the same time, the vibration formed by the vibrating plate 37 can improve the speed and uniformity of the material collection trough 33. When the material collection trough 33 is filled with material and enters the cylindrical groove 23, the material will be temporarily stored inside the material collection trough 33 because the gap between the cylindrical plate 32 and the cylindrical box 21 is not enough for the material to flow out. When the material collection trough 33 is aligned with the discharge port 26, the material will fall from the material collection trough 33 and the discharge port 26 into the extruder 1 under the action of vibration and its own gravity, thus achieving the feeding effect. The device optimizes the feeding method of polypropylene granules, improves the uniformity of conveying to the extruder 1, reduces the impact of vibration on the equipment, and can stably feed even if the granules agglomerate, ensuring the stable operation of the extruder 1, improving the molding quality of the foamed insulation layer, and enhancing production efficiency and product performance.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
