Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and in particular to a cable tension storage rack. Background Technology

[0002] In traditional cable extrusion processes, the core wire needs to be fed into the extruder through an infeeding mechanism, and an injection molding layer is wrapped around the core wire to form an insulation layer.

[0003] Currently, most cable extrusion equipment uses a simple tensioning mechanism for the core wire feeding mechanism. After tensioning, the core wire is directly fed into the extruder for coating. This design has a significant drawback: when the core wire is exhausted, the extruder cannot be stopped in time, causing it to continue operating. The extruded plastic material does not contain the core wire, resulting in raw material waste and equipment idling. This not only increases production costs but also affects production efficiency and product quality. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a wire tension storage rack, which solves the technical problem that existing cable extrusion equipment cannot provide operators with time to stop the extruder when the core wire is exhausted.

[0005] According to an embodiment of the present invention, a wire tension storage rack includes a support frame, guide wheels disposed on both sides of the support frame, and an elastic wire storage mechanism disposed in the middle of the support frame.

[0006] The elastic wire storage mechanism includes an upper wire storage wheel, a lower wire storage wheel, and a sliding rod. The sliding rod is vertically mounted on a support frame. The upper and lower wire storage wheels are movably mounted on the sliding rod. An elastic element is provided between the upper and lower wire storage wheels, and the elastic element is also sleeved on the sliding rod.

[0007] The technical principle of this utility model is as follows: When in use, the core wire is drawn out from the inlet mechanism, then introduced into the guide wheel on one side, and then wound around the upper and lower wire storage wheels for at least one turn. Then it is drawn out from another guide wheel and enters the cable extrusion equipment for extrusion processing.

[0008] The core wires on the upper and lower wire storage reels can continue to support the processing of the cable extrusion equipment when the cable is exhausted, giving the operator time to shut down the cable extrusion equipment.

[0009] The elastic element between the upper and lower cable reels here can provide tension to the cable, replacing the original tensioning mechanism.

[0010] Compared with the prior art, this utility model has the following advantages: by using an upper and lower wire storage wheel with elastic elements and two guide wheels, it solves the technical problem that existing cable extrusion equipment cannot give operators time to stop the extruder when the core wire is used up.

[0011] This application presents a technical solution for the low-cost retrofitting of existing outdated extrusion equipment. Although there are existing technical solutions that use sensors to directly stop cable extrusion equipment, these solutions rely on a completely new control system, which results in higher retrofitting costs.

[0012] Furthermore, the sliding rod has an annular protrusion in the middle, and the elastic element consists of two compression springs, which are respectively disposed between the annular protrusion and the upper or lower wire storage wheel.

[0013] Furthermore, the sliding rod is provided with two rods, one of which is equipped with an elastic element. The upper and lower wire storage wheels and the two sliding rods are movably connected respectively.

[0014] Furthermore, two support plates are fitted onto the sliding rod, and an upper wire storage wheel and a lower wire storage wheel are respectively installed on the two support plates.

[0015] Furthermore, the support frame has elongated holes vertically on both sides, and the two guide wheels are respectively installed in the two elongated holes.

[0016] Furthermore, a wire feeding device is provided on one side of the support frame, and a guide mechanism is provided between the wire feeding device and the support frame.

[0017] Furthermore, the guiding mechanism includes two vertically arranged guide rollers and one horizontally arranged guide roller, with a common support rod under the three guide rollers.

[0018] The use of three guide rollers ensures that the core wire can be accurately guided onto the guide wheel.

[0019] Furthermore, an extruder is provided on one side of the support frame, and an elastic tensioning mechanism is provided between the extruder and the support frame.

[0020] Furthermore, the elastic tensioning mechanism includes a base support and a plurality of tensioning wheels arranged along the length of the base support, with adjacent tensioning wheels being vertically offset from each other.

[0021] Furthermore, the base bracket has a vertical strip hole corresponding to each tension wheel, and the tension wheel has a connecting rod passing through the strip hole. A tension spring is connected to the upper or lower side of the connecting rod, and the tension springs of adjacent connecting rods are arranged in opposite directions. The end of the tension spring away from the connecting rod is fixed to the base bracket.

[0022] A new elastic tensioning mechanism is designed to address situations where the tension of the upper and lower wire storage reels is insufficient. Attached Figure Description

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] like Figure 1 The wire tension storage rack shown is characterized by: including a support frame 1, guide wheels 2 arranged on both sides of the support frame 1, and an elastic wire storage mechanism 3 arranged in the middle of the support frame 1; a wire feeding device 4 is provided on one side of the support frame 1, a guide mechanism 5 is provided between the wire feeding device 4 and the support frame 1, and an extruder 6 is provided on the other side of the support frame 1, so that the core wire is led out at the wire feeding device 4 and enters the extrusion head 61 of the extruder 6 through the guide mechanism 5 and the wire tension storage rack in sequence.

[0034] like Figure 2 As shown, the unwinding device 4 includes a frame 41 and an unwinding roller 42 mounted on the frame 41. The unwinding roller 42 is connected to a motor 43 for driving. The unwinding roller 42 is used to support the wound core wire. The motor 43 drives the unwinding roller 42 to rotate for actively drawing out the core wire.

[0035] like Figure 3 As shown, the guiding mechanism 5 includes two vertically arranged guide rollers 51 and one horizontally arranged guide roller 51. The three guide rollers 51 are provided with a common support rod 52. The core wire passes between the two vertical guide rollers 51 and is located on the upper side of the horizontal guide roller 51.

[0036] like Figure 1 , 4 As shown, the elastic wire storage mechanism 3 includes an upper wire storage wheel 31, a lower wire storage wheel 32, and two sliding rods 33. The two sliding rods 33 are vertically mounted on the support frame 1. The upper wire storage wheel 31, the lower wire storage wheel 32, and the two sliding rods 33 are movably connected. Specifically, one of the sliding rods 33 has an annular protrusion 331 in the middle. An elastic element 332 is provided between the annular protrusion 331 and the upper wire storage wheel 31 or the lower wire storage wheel 32. The elastic element 332 is a compression spring and is also sleeved on the sliding rod 33.

[0037] Specifically, two sliding rods 33 are fitted with two support plates 333. The upper wire storage wheel 31 and the lower wire storage wheel 32 are respectively mounted on the two support plates 333 using bearings. The compression spring can then transmit the elastic force to the upper wire storage wheel 31 and the lower wire storage wheel 32, thereby forming a tension force on the core wire.

[0038] like Figure 1 , 5 As shown, the support frame 1 has elongated holes 11 vertically on both sides, and two guide wheels 2 are respectively installed in the two elongated holes 11 with bolts, so that the horizontal height of the guide wheels 2 can be adjusted according to actual needs.

[0039] Example 2

[0040] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that: an elastic tensioning mechanism 7 is provided between the extruder 6 and the support frame 1. The specific elastic tensioning mechanism 7 includes a base support 71 and a plurality of tensioning wheels 72 arranged along the length of the base support 71. The adjacent tensioning wheels 72 are vertically staggered. When in use, the core wire is passed through the tensioning wheels 72 on the side that is close to each other.

[0041] like Figure 6-7As shown, the base bracket 71 has a vertical strip hole 711 corresponding to each tension wheel 72. The tension wheel 72 has a connecting rod 721 that passes through and is installed on the strip hole 711, that is, the connecting rod 721 can move along the strip hole 711. A tension spring 722 is connected to the upper or lower side of the connecting rod 721. The tension springs 722 of adjacent connecting rods 721 are set in opposite directions. The end of the tension spring 722 away from the connecting rod 721 is fixed to the base bracket 71. That is, the tension spring 722 provides tension when it is set on the upper side and provides thrust when it is set on the lower side.

[0042] The tension spring 722 provides a large and stable tension force to the core wire.
