Description

Technical Field

[0001] This utility model relates to a cable extrusion vacuum adjustment device, belonging to the technical field of cable production equipment. Background Technology

[0002] In modern cable manufacturing, extrusion molding is widely used in the continuous production of cable surface insulation layers. To improve the quality of cable surface molding and avoid air interference, many production processes employ vacuuming during extrusion. Because the size and shape of the cable change during the extrusion process, it is necessary to adjust the gap between the cable and the extruder edge to reduce the entry of air or other impurities into the cable extruder.

[0003] In the cable extrusion vacuuming process, a hollow plate with a fixed gap is typically placed on the edge of the cable extrusion vacuuming device to adjust the gap between the cable and the edge of the device. However, this adjustment method does not change when the cable diameter changes, leading to unevenness or material loss during actual processing. The adjustment process requires disassembling the hollow plate and replacing it with one of suitable diameter, resulting in low efficiency and difficulty in meeting the continuous and stable requirements of large-scale production. Therefore, a cable extrusion vacuuming adjustment device needs to be designed to adjust the distance between the cable and the edge of the extrusion vacuuming device. Utility Model Content

[0023] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] like Figures 1-4 As shown, a cable extrusion vacuum adjustment device includes a fixing device 1 and an adjustment device 2, with the adjustment device 2 disposed at the bottom of the fixing device 1.

[0026] The bottom of the fixing device 1 is provided with a groove for fixing the adjusting device 2, and the middle of the fixing device 1 is provided with a through hole to accommodate the cable 4. The top of the fixing device 1 is connected to the extrusion device 3 by bolts.

[0027] In this embodiment, the fixing device 1 is mainly used to stably install the adjusting device 2 at the inlet of the extrusion device 3, so as to ensure that the cable 4 can reduce the entry of air, dust or other debris into the extrusion device 3 during the vacuuming process of entering the extrusion device 3.

[0028] Reference Figure 1 , Figure 3 , Figure 4 The adjusting device 2 includes multiple rotatable blades 21, a base 23, and a drive plate 22. The gap between the blades 21 and the cable 4 can be controlled by rotating the drive plate 22 to ensure the quality of the extruded product.

[0029] Reference Figure 1 , Figure 2 The fixing device 1 has a ring-shaped structure with a through hole in the center to accommodate the cable 4. Multiple bolts are provided on the top of the fixing device, and the top of the fixing device 1 is connected to the extrusion device 3 by the bolts to ensure that the adjusting device 2 can be set in the external position in front of the wire inlet buckle of the extrusion device 3, so that it is not easy to shake or fall off.

[0030] The bottom of the fixing device 1 is provided with a groove for fixing the adjusting device 2, which is used to accommodate and support the adjusting device 2. In this embodiment, the groove is an annular groove, and a buckle is provided at the edge of the groove, so that the adjusting device 2 can be fixed to the bottom of the fixing device 1 by the buckle.

[0031] The adjusting device 2 has a ring-shaped structure. Multiple blades 21 form holes in the center of the adjusting device 2, and the diameter of these holes can be adjusted. After the adjusting device 2 is fixed to the fixing device 1, it ensures that the central axis of the adjusting device 2 is coaxial with the extrusion device 3 and the cable 4, reducing coaxiality errors and minimizing their impact on subsequent adjustment accuracy. In this embodiment, the top outer side of the fixing device 1 gradually tapers inward. The fixing device 1 is connected to the extrusion device 3 by bolts, and the fixing device 1 is connected to the adjusting device 2 by snap-fit ​​connections. The fixing device 1 can withstand a certain amount of vibration during production and prevents the device from loosening.

[0032] The adjusting device 2 includes blades 21, a base 23, and a drive plate 22. Multiple blades 21 can form holes in the middle of the adjusting device 2. The diameter of the holes can be adjusted by the angle between the blades 21, which can adjust the gap between the cable and the edge of the extruder and reduce the entry of air or other debris into the cable extruder.

[0033] Reference Figure 4 The base 23 is circular with a through hole at its center, through which the cable 4 can pass. This design allows for adjustment based on different diameters and structures. In this embodiment, the outer side of the base 23 has multiple grooves for easy fixing to the drive plate 22, ensuring that the base 23 can provide support and fixation for the blade 21 and the drive plate 22. Multiple protrusions 231 are distributed circumferentially on the upper surface of the base 23, and these protrusions 231 can mate with pre-drilled fixing holes on the blade 21. When the bottom fixing hole of the blade 21 connects with the protrusion 231 of the base 23, one end can swing around the protrusion, forming a stable mechanical connection between the blade 21 and the base 23.

[0034] Reference Figure 1 , Figure 3 In this embodiment, the blades 21 are arc-shaped, and after being combined, they form a circular opening with an adjustable inner diameter. In this embodiment, multiple blades 21 are evenly arranged along the circumference of the base 23 and overlap each other to form a ring structure. The bottom of each blade 21 has a fixing hole, and a corresponding protrusion 231 is provided on the base 23, allowing the multiple blades 21 to be fixed to the base 23 through the fixing holes at the bottom. In this embodiment, the number and spacing of the fixing holes are matched to the number and arrangement of the blades 211, ensuring that the angles formed between the blades 21 and the base 23 are consistent. An adjusting rod is provided on the surface of each blade 21, which engages with a groove on the drive plate 22. When the drive plate 22 rotates, it drives the adjusting rod to change the angle between the blades 21, thus enlarging or shrinking the central opening.

[0035] Reference Figure 1 , Figure 3The drive plate 22 is arranged in parallel with the base 23. The drive plate 22 is in the shape of a ring and has an opening in the middle for the adapter cable 4 to pass through. The number of grooves 222 on the drive plate 22 is the same as the number of blades 21 and the spacing is consistent, which can realize the synchronous drive of all blades 21.

[0036] A push rod 221 is provided on the surface of the drive plate 22. During adjustment, the operator can push the push rod 221 with external force, thereby causing the entire drive plate 22 to generate a circumferential displacement with respect to the base 23. In this embodiment, the push rod 221 and the drive plate 22 are integrally connected. The groove 222 provided on the drive plate 22 can accommodate the adjustment rod of the blade 21. The drive plate 22 is rotated by the push rod 221. At this time, the adjustment rod provided inside the groove 222 can move, causing the angle of the blade 21 to change, thereby adjusting the size of the central opening. When the direction of the central opening is reduced to be close to the outer diameter of the cable 4, it can reduce the entry of dust or other debris or air into the extrusion device 3, thereby improving the surface quality of the extruded product.

[0037] In this embodiment, the top of the fixing device 1 is connected to the extrusion device 3 by bolts, and the adjusting device 2 is located at the inlet where the cable 4 enters the extrusion device 3. The fixing device 1 serves to support and position the cable. Furthermore, the centers of the cable 4, the extrusion device 3, the fixing device 1, and the adjusting device 2 are all on the same axis.

[0038] The bottom groove of the fixing device 1 can accommodate the adjusting device 2, and the bottom of the fixing device 1 is provided with a buckle to fix the adjusting device 2. The buckle and the groove can ensure that the adjusting device 2 is not easily loosened or deviated at the bottom of the fixing device 1 and can ensure that the drive plate 22 can move on the base 23.

[0039] The protrusion 231 on the base 23 fixes the bottom of the blade 21 through the fixing hole and provides a fulcrum for the blade 21. The surface of the blade 21 is provided with an adjusting rod that engages with the groove 222 of the drive plate 22. When the push rod 221 on the drive plate 22 is pushed, the drive plate 22 rotates around the central axis and drives all the blades 21 to swing synchronously. The blades 21 can overlap or expand with each other, forming a hollow hole in the central area that can change diameter. The cable 4 is located at the center of the hollow hole. When the central opening shrinks to match the outer diameter of the cable (4) or is only slightly larger than the size of the cable 4, it can reduce the entry of air or other debris into the cable extruder.

[0040] This embodiment, through the linkage between the drive plate 22 and the blade 21, enables rapid adjustment according to the outer diameter of the cable 4 during the production process, which is more convenient and faster than traditional adjustment methods. The separate design of the blade 21, base 23, and drive plate 22 makes disassembly and replacement convenient; with the bolt connection between the fixing device 1 and the extrusion device, and the snap-fit ​​connection between the fixing device 1 and the adjustment device 2, the corresponding parts can be quickly replaced during maintenance or production line changeover. It can adapt to various cable specifications or extrusion requirements. By simply selecting the appropriate blade size and quantity according to different diameters and wire characteristics, it can be widely used in the cable manufacturing field.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model. All such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
