[0002] During the process of continuously extruding wire and cable, due to factors such as the irregular bundling of the aluminum rod wire reels themselves, the loose arrangement of the aluminum rods, and the relatively large diameter of the wire reels, situations such as the aluminum rods getting tangled or knotted easily occur during the wire pay-off process of the aluminum rods, resulting in the aluminum rods being jammed.

[0003] To smoothly pay off the wire and reduce the occurrence of wire tangling, it is necessary to increase the height of the wire pay-off rack. Generally, the height of the wire pay-off rack reaches about 5 meters. Due to the excessive height of the wire pay-off rack, a ladder needs to be provided on the wire pay-off rack. When replacing the wire reel and threading the wire, it is necessary to climb the ladder to the top of the wire pay-off rack for threading operations. This operation method is not only cumbersome and time-consuming, but also poses a safety hazard for working at heights.

[0004] Therefore, there is an urgent need to provide a liftable wire pay-off rack to solve the above problems existing in the prior art. Summary of the Utility Model

[0026] The purpose of the present invention is to provide a liftable wire reel and a continuous extrusion machine assembly to solve the above problems existing in the prior art, which can thread wires without climbing heights, is convenient for threading, and reduces potential safety hazards.

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] Embodiment 1

[0029] As Figures 1 - 3As shown in the figure, in this embodiment, a liftable wire reel is provided, which mainly includes a main frame body. A wire guide wheel set is arranged on the main frame body for guiding the aluminum rod. Among them, the main frame body includes a vertical support beam 7 and a lifting cross beam 2. The bottom of the vertical support beam 7 is used to be fixed on the ground. A linear guide rail 12 is arranged on the vertical support beam 7 along its height direction. The lifting cross beam 2 is perpendicular to the vertical support beam 7, and one end of the lifting cross beam 2 is slidably arranged on the linear guide rail 12. The lifting cross beam 2 is also connected with a power mechanism, and the power mechanism is used to drive the lifting cross beam 2 to move up and down along the linear guide rail 12.

[0030] In this embodiment, the power mechanism can drive the lifting cross beam 2 to move up and down along the linear guide rail 12. When threading is required, the lifting cross beam 2 is lowered, so that workers can thread without climbing heights. The threading is convenient and the safety hazard is reduced. After the threading is completed, the power mechanism drives the lifting cross beam 2 to rise to the specified height, and then the work can be carried out.

[0031] In this embodiment, the bottom of the vertical support beam 7 is fixed on the ground through a fixed base to improve stability. Among them, the fixed base can be set according to specific working needs. For example, as Figure 1 and Figure 2 shown, the fixed base includes a fixed bottom plate, and the fixed bottom plate can be fixed on the ground by bolts. The bottom of the vertical support beam 7 can be fixedly connected to the fixed bottom plate by welding or other means. And a triangular support rib plate is also arranged between the vertical support beam 7 and the fixed bottom plate to improve the overall stability.

[0032] In this embodiment, the wire guide wheel set includes three wire guide wheels 3. Among them, two of the wire guide wheels 3 are respectively arranged at both ends of the lifting cross beam 2, and the other wire guide wheel 3 is arranged at the bottom of one side of the vertical support beam 7. Or, the number and installation positions of the wire guide wheels 3 can also be adjusted according to specific working needs, as long as the wire requirements are met.

[0033] In this embodiment, a wire passing hole is opened at one end of the lifting cross beam 2 away from the vertical support beam 7, and a wire passing ring is arranged at the bottom of the wire passing hole. Among them, the wire passing ring is preferably a conical wire passing ring, and the diameter of the wire passing ring gradually increases from top to bottom. When paying off the wire, the aluminum rod passes through the wire passing ring and the wire passing hole in sequence, and then winds around the wire guide wheel 3. The settings of the wire passing ring and the wire passing hole can ensure the smooth pay-off of the aluminum rod.

[0034] In this embodiment, the power mechanism is a winch 4, which is arranged at the top of the vertical support beam 7. The winch 4 is connected to the lifting cross beam 2 through a steel wire rope. By taking in the wire of the winch 4, the lifting cross beam 2 can be driven to rise, and by paying out the wire of the winch 4, the lifting cross beam 2 can be made to descend under its own gravity. Further, other power mechanisms can also be selected according to the working needs, such as a lifting cylinder or a lead screw nut mechanism, etc.

[0035] In this embodiment, an upper limit member 10 is arranged at the top of the vertical support beam 7, and a lower limit member 9 is arranged at the bottom. The upper limit member 10 and the lower limit member 9 are used to limit the lifting range of the lifting cross beam 2. Among them, the upper limit member 10 and the lower limit member 9 are preferably mechanical limit members such as limit blocks.

[0036] Further, an upper proximity switch 6 is also arranged at the top of the vertical support beam 7, and a lower proximity switch 8 is also arranged at the bottom. The upper proximity switch 6 is arranged close to the upper limit member 10. When the lifting cross beam 2 moves upward to contact the upper limit member 10, the upper proximity switch 6 is triggered and the winch 4 is turned off. The lower proximity switch 8 is arranged close to the lower limit member 9. When the lifting cross beam 2 moves downward to contact the lower limit member 9, the lower proximity switch 8 is triggered and the winch 4 stops paying out the wire.

[0037] In this embodiment, a locking mechanism is also arranged on the vertical support beam 7. When the lifting cross beam 2 moves upward to contact the upper limit member 10, the locking mechanism locks the lifting cross beam 2, which can prevent it from accidentally falling and ensure safety. At this time, the winch 4 is turned off. As a preferred implementation manner, the locking mechanism includes a pin cylinder 5. The end of the cylinder rod of the pin cylinder 5 is connected with a positioning pin 11. A positioning hole is correspondingly arranged on the lifting cross beam 2. When the lifting cross beam 2 moves upward to contact the upper limit member 10, the pin cylinder 5 can push the positioning pin 11 into the corresponding positioning hole to realize the locking of the lifting cross beam 2. Moreover, two pin cylinders 5 are arranged, and the two pin cylinders 5 are symmetrically arranged on both sides of the lifting cross beam 2, and the pin cylinder 5 is perpendicular to the lifting cross beam 2.

[0038] The working process of the liftable wire laying frame in this embodiment is as follows:

[0039] During the wire threading operation, the positioning pin 11 is pulled out, the winch 4 pays out the wire, and the lifting cross beam 2 descends until it contacts the lower limit member 9. The lower proximity switch 8 is triggered and the winch 4 stops paying out the wire. At this time, the operator can perform the wire threading operation on the ground, which is safe and convenient.

[0040] After completing the threading operation, use the winch 4 to lift the lifting crossbeam 2 until it contacts the upper limit member 10, trigger the upper proximity switch 6, insert the positioning pin 11 into the corresponding positioning hole on the lifting crossbeam 2 by the pin cylinder 5, and turn off the winch 4 to enter the working state.

[0041] In this embodiment, a continuous extrusion machine assembly is further provided, including a continuous extrusion machine and the liftable wire pay-off frame as described above.

[0042] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
