Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a cable insulation extrusion uniformity adjustment device. Background Technology

[0002] Cable insulation extrusion refers to the process in wire and cable manufacturing where insulating materials (such as polyethylene, polyvinyl chloride, ethylene propylene rubber, etc.) are uniformly wrapped around the conductor using an extruder to form an insulation layer. This process is accomplished by the extruder and the die. First, the plastic raw material is heated to a molten state in the extruder. Then, the molten plastic is uniformly pushed to the die by the screw. In the die, the molten plastic is extruded through a mold of a specific shape (such as the annular gap between the die core and the die sleeve) and wrapped around the conductor or wire core to form a continuous and uniform insulation layer or sheath layer.

[0003] In existing technologies, when the conductor is pulled into the die, it is easily affected by speed fluctuations of the traction equipment, differences in its own rigidity, or slight external vibrations. This can exacerbate the relative positional deviation between the conductor and the extrusion die, making it difficult to control the concentricity of the conductor and the die. This results in uneven distribution of insulation layer thickness (such as one side being thicker and the other side being thinner). Therefore, we propose a cable insulation extrusion uniformity adjustment device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cable insulation extrusion uniformity adjustment device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cable insulation extrusion uniformity adjustment device includes a frame, an extruder body fixedly connected to the outer wall of the frame, an outer wall of a hopper fixedly connected to the outer wall of the frame, a threaded hole in the outer wall of the frame, a threaded rod threadedly connected to the inner wall of the threaded hole, a turntable fixedly connected to the top of the threaded rod, a T-shaped column fixedly connected to the bottom of the threaded rod, a rectangular rod rotatably sleeved on the outer wall of the T-shaped column, a rectangular sleeve slidably sleeved on the outer wall of the rectangular rod, a connecting column fixedly connected to the outer wall of the rectangular sleeve, one end of the connecting column fixedly connected to the outer wall of the frame, a fixed plate fixedly connected to the bottom of the rectangular rod, and an adjustment component on the outer wall of the fixed plate.

[0007] Preferably, the adjustment assembly includes two T-shaped pieces, one end of each of the two T-shaped pieces being fixedly connected to the outer wall of the fixed disk. An adjustment disk is rotatably sleeved on the outer wall of each of the two T-shaped pieces, and a tapered guide rod is fixedly connected to the bottom of each of the two adjustment disks. Multiple adjustment holes are evenly opened on the outer walls of the fixed disk and the two adjustment disks, and a pin is slidably connected to the inner wall of each adjustment hole. The distance between the two tapered guide rods can be adjusted by setting the adjustment assembly.

[0008] Preferably, the outer wall of the extruder body is fixedly connected to a material hopper.

[0009] Preferably, the bottom of the extruder body is fixedly connected to a die head.

[0010] Preferably, the fixing plate is located on one side of the mold head.

[0011] Preferably, the outer wall of the adjusting disc is slidably connected to the outer wall of the fixed disc.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses a V-shaped guide structure composed of two tapered guide rods to laterally limit the conductor, reducing lateral swaying and longitudinal movement of the conductor, and providing a stable foundation for uniform extrusion of the insulation layer;

[0014] By moving the rectangular rod vertically and by using the guiding effect of the V-shaped structure, the positional deviation of the conductor can be corrected, ensuring that the conductor axis is always aligned with the center of the die.

[0015] The angle between the two tapered guide rods can be adjusted by rotating the adjustment disc. Combined with the fixing method of the adjustment hole and the pin shaft, it can quickly adapt to conductors of various diameters without frequent replacement. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Depend on Figures 1-3 As shown, a cable insulation extrusion uniformity adjustment device is disclosed, including a frame 1, an extruder body 2 (TF-70) is fixedly connected to the outer wall of the frame 1, a hopper 3 is fixedly connected to the outer wall of the extruder body 2 (TF-70), the hopper 3 supplies raw materials to the extruder, and a die head 4 is fixedly connected to the bottom of the extruder body 2 (TF-70).

[0023] The outer wall of the hopper 3 is fixedly connected to the outer wall of the frame 1. The outer wall of the frame 1 is provided with a threaded hole. A threaded rod 5 is threadedly connected to the inner wall of the threaded hole. A turntable 6 is fixedly connected to the top of the threaded rod 5. A T-shaped column is fixedly connected to the bottom of the threaded rod 5. A rectangular rod 9 is rotatably sleeved on the outer wall of the T-shaped column. The threaded rod 5 converts the rotational motion of the turntable 6 into the linear motion of the rectangular rod 9.

[0024] A rectangular sleeve 7 is slidably fitted on the outer wall of the rectangular rod 9. A connecting column 8 is fixedly connected to the outer wall of the rectangular sleeve 7. One end of the connecting column 8 is fixedly connected to the outer wall of the frame 1. The rectangular sleeve 7 allows the rectangular rod 9 to move only vertically up and down, avoiding lateral offset or rotation. A fixing plate 10 is fixedly connected to the bottom of the rectangular rod 9. The fixing plate 10 is located on one side of the mold head 4.

[0025] The outer wall of the fixed disk 10 is provided with an adjustment assembly, which includes two T-shaped pieces 11. One end of each of the two T-shaped pieces 11 is fixedly connected to the outer wall of the fixed disk 10. The outer wall of each of the two T-shaped pieces 11 is rotatably fitted with an adjustment disk 12. The T-shaped pieces 11 provide a rotation fulcrum for the adjustment disk 12 and limit the axial displacement of the adjustment disk 12 (to prevent it from falling off).

[0026] The outer wall of the adjusting plate 12 is slidably connected to the outer wall of the fixed plate 10. A tapered guide rod 13 is fixedly connected to the bottom of each of the two adjusting plates 12. The outer surface of the tapered guide rod 13 is relatively smooth, which plays a good guiding role. Multiple adjusting holes 14 are evenly opened on the outer walls of the fixed plate 10 and the two adjusting plates 12. A pin 15 is slidably connected to the inner wall of the adjusting hole 14. The adjusting plate 12 drives the tapered guide rod 13 to change the included angle by rotating, so as to adapt to conductors of different diameters. The outer wall of the pin 15 is provided with a pin hole, and a direction adjustment component can be added in the conductor path of the traction equipment to ensure its stability.

[0027] Working principle: During use, the conductor passes through the die head 4, and both ends of the conductor are conveyed by existing traction equipment. Rotating the turntable 6 drives the threaded rod 5 to rotate, which in turn drives the rectangular rod 9 to move downwards. Because the threaded rod 5 and the rectangular rod 9 are rotatably connected by a T-shaped column, the rectangular rod 9 can move up and down with the threaded rod 5, but it does not rotate with it. During its up and down movement, the rectangular rod 9 is ensured to be dragged vertically downwards by the rectangular sleeve 7. The downward movement of the rectangular rod 9 drives the fixed plate 10 to move downwards, which in turn drives the two adjusting plates 12 to move downwards. The downward movement causes the two tapered guide rods 13 to move downwards. After moving downwards, the two tapered guide rods 13 are located on the left and right sides of the conductor, respectively. The two tapered guide rods 13 are V-shaped, which helps the conductor to move stably, ensures that the conductor and the die head 4 are in the same axis position, and prevents the conductor from jumping upwards during traction. Since the two tapered guide rods 13 rotate through the rotation of the two adjusting discs 12, they can meet the needs of conductors of different thicknesses. After rotation, by inserting the pin 15 into the adjusting hole 14 and then inserting the existing cotter pin into the pin hole on the outer wall of the pin 15, the two adjusting discs 12 can be fixed on the fixed disc 10.
