Description

Technical Field

[0001] This utility model relates to the field of cable production equipment technology, specifically to a cable stabilizing device for cable production. Background Technology

[0002] As is well known, a winding device is usually installed at the end of a cable production line to facilitate storage and transportation. However, the linear characteristics of cables make them prone to vibration when conveyed to the winding device, so a cable stabilizing device is usually installed in front of the winding device.

[0003] For example, CN 222860829 U discloses a cable stabilizing device for cable production, which includes a base plate with at least two sets of frames. A bearing plate is fixed on each frame, and four sets of stabilizing mechanisms arranged in a grid pattern are arranged within the frames. Two of these stabilizing mechanisms are staggered from the other two. Each stabilizing mechanism includes a housing fixed within the frame, with a sliding rod slidably mounted on the housing. A top plate and a frame are fixed to the two ends of the sliding rod, respectively, and a suspension spring is fitted onto the sliding rod. Guide rollers that rotatably contact the cable surface are mounted on the frame. The grid-patterned stabilizing mechanism allows the input cable to pass through the four sets of guide rollers. Under the action of the suspension springs, the four sets of guide rollers apply inward pressure to compress and constrain the cable, achieving multi-directional restriction and thus improving the stability of the cable output. However, the following problems still exist: 1. When the cable conveying speed fluctuates, the cable's conveying state is unstable, affecting the stability of the winding operation of the winding device; 2. At low ambient temperatures, the cable's hardness is high, making it difficult to wind. Utility Model Content

[0004] The purpose of this invention is to provide a cable stabilizing device with a reasonable structure and reliable use that solves the above-mentioned problems. Compared with the prior art, while ensuring the stabilizing function, it has a cable conveying buffer function to ensure the stability of the winding operation. On the other hand, it has a function of heating and softening the cable when the ambient temperature is low, which is beneficial to the winding operation.

[0005] The technical solution of this utility model is:

[0006] A cable stabilizing device for cable production includes a portal frame and a stabilizing mechanism. The key technical features are as follows: the stabilizing mechanism includes multiple lower support rollers spaced apart along the length of the portal frame, a lifting cylinder located at the top of the portal frame, a lifting frame connected to the lifting cylinder, upper pressure rollers located on the lifting frame and corresponding to each lower support roller, and a self-lifting intermediate guide roller located between two adjacent lower support rollers. The side wall of the portal frame has longitudinal grooves corresponding to the roller shafts of the self-lifting intermediate guide rollers. The outer circumferential surfaces of the lower support rollers, upper pressure rollers, and self-lifting intermediate guide rollers are respectively provided with annular limiting grooves. The roller shaft of the lower support rollers is a hollow shaft. One end of the hollow shaft leads out of the portal frame and connects to a first rotary joint. The other end of each first rotary joint is connected to the outlet of a heating medium distribution pipeline. The other end of the hollow shaft leads out of the portal frame and connects to a second rotary joint. The other end of each second rotary joint is connected to the inlet of a heating medium confluence pipeline.

[0007] The above-mentioned cable stabilizing device for cable production has two lifting cylinders, which are fixed at intervals on the top of the portal frame. The lifting frame consists of a linkage plate fixed to the upper end of the cylinder rod of the two lifting cylinders, multiple guide columns on the lower surface of the linkage plate, and a wheel frame on the lower end of the guide columns. The top surface of the portal frame is provided with guide sleeves corresponding to the guide columns.

[0008] In the aforementioned cable production stabilizing device, a bearing is provided between the roller shaft of the self-lifting intermediate guide roller and the self-lifting intermediate guide roller.

[0009] The aforementioned cable stabilizing device for cable production has a limiting block at the outer end of the roller shaft of the self-lifting intermediate guide roller.

[0010] The aforementioned cable stabilizing device for cable production has a first support corresponding to the heating medium diversion pipeline and a second support corresponding to the heating medium manifold pipeline on the outer wall of the portal frame.

[0011] The aforementioned cable stabilizing device for cable production has a reverse support edge at the lower end of the two side walls of the portal bracket, and a set of fixing holes on the reverse support edge.

[0012] The beneficial effects of this utility model are:

[0013] 1. The upper pressure roller and the lower support roller correspond one-to-one and use the annular limiting groove to limit the cable, avoid cable jumpers, and achieve the function of stabilizing the cable.

[0014] 2. The self-lifting intermediate guide roller serves as a buffer during the conveying process, adapting to fluctuations in cable conveying speed and ensuring stable conveying, thereby guaranteeing the stability of the winding operation.

[0015] 3. The lower support roller is heated by circulating heating medium through the heating medium distribution pipeline and the heating medium collection pipeline, which serves to heat and soften the cable, thus facilitating the winding operation. Attached Figure Description

[0020] The present invention will be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-3 As shown, the cable stabilizing device for cable production includes a portal frame 8 and a stabilizing mechanism.

[0022] The stabilizing mechanism includes three lower support rollers 15 spaced apart along the length of the portal frame 8, a lifting cylinder 2 located at the top of the portal frame 8, a lifting frame connected to the lifting cylinder 2, an upper pressure roller 14 located on the lifting frame and corresponding to each of the lower support rollers 15, and a self-lifting intermediate guide roller 21 located between two adjacent lower support rollers 15.

[0023] The side wall of the portal frame 8 is provided with a longitudinal groove 12 corresponding to the roller shaft of the self-lifting intermediate guide roller 21. The outer circumferential surfaces of the lower support roller 15, upper pressure roller 14, and self-lifting intermediate guide roller 21 are respectively provided with annular limiting grooves 19. In this embodiment, there are two lifting cylinders 2, fixed at intervals to the top of the portal frame 8. The lifting frame consists of a linkage plate 1 fixed to the upper end of the cylinder rods of the two lifting cylinders 2, multiple guide columns 3 located on the lower surface of the linkage plate 1, and a wheel frame 13 located at the lower end of the guide columns 3. The top surface of the portal frame 8 is provided with a guide sleeve 4 corresponding to the guide columns 3. A bearing 22 is provided between the roller shaft of the self-lifting intermediate guide roller 21 and the self-lifting intermediate guide roller 21. A limiting block 10 is provided at the outer end of the roller shaft of the self-lifting intermediate guide roller 21.

[0024] The lower support roller 15 has a hollow shaft. One end of the hollow shaft leads out of the gate-shaped bracket 8 and connects to the first rotary joint 16. The other end of each first rotary joint 16 is connected to the outlet of the heating medium distribution pipe 5. The other end of the hollow shaft leads out of the gate-shaped bracket 8 and connects to the second rotary joint 18. The other end of each second rotary joint 18 is connected to the inlet of the heating medium manifold pipe 17. In this embodiment, the outer wall of the gate-shaped bracket 8 is provided with a first support 9 corresponding to the heating medium distribution pipe 5 and a second support 20 corresponding to the heating medium manifold pipe 17.

[0025] The lower ends of the two side walls of the portal bracket 8 are provided with a reverse support edge 11, and the reverse support edge 11 is provided with a group of fixing holes.

[0026] Working principle:

[0027] When using, please refer to Figure 3 The end of the cable 6 passes sequentially around the first lower support roller 15, the first self-lifting intermediate guide roller 21, the second lower support roller 15, the second self-lifting intermediate guide roller 21, and the third lower support roller 15, and then extends towards the winding device 7. Finally, the lifting cylinder 2 is activated, which drives the three upper pressure rollers 14 to move downward through the lifting frame. These rollers correspond one-to-one with the three lower support rollers 15 and limit the cable 6, preventing the cable 6 from jumping and achieving the function of stabilizing the cable.

[0028] Meanwhile, the two self-lifting intermediate guide rollers 21 act as counterweights. When the cable 6 is conveyed at a relatively fast speed, the self-lifting intermediate guide rollers 21 are positioned lower in the longitudinal groove 12. When the cable 6 is conveyed at a relatively slow speed, the self-lifting intermediate guide rollers 21 are positioned higher in the longitudinal groove 12, which serves as a conveying buffer function. This can adapt to fluctuations in the cable conveying speed, ensure that the conveying state is not unstable, and thus ensure the stability of the winding operation.

[0029] When the ambient temperature is low and the cable is hard, heating medium is injected into the lower support roller 15 through the heating medium diversion pipe 5. The heating medium then flows to the heat exchange system through the heating medium manifold pipe 17. This cycle is repeated to heat and soften the cable 6, which is beneficial for the winding operation.

[0030] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
