Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary device for cable manufacturing, specifically a cable-forming machine output wheel guide. Background Technology
[0002] In current network cable production processes, the cabling process typically employs a cantilevered single-strand cabling machine. This machine features a cantilever 4 with a lead-out reel 6 and a take-up reel 5, both driven by a drive mechanism (existing technology, omitted in the diagram) that rotates at high speed (the take-up reel also performs axial reciprocating linear motion). The difference in their rotational speeds ensures that the cable, guided by the lead-out reel, is regularly wound onto the take-up reel. A drawback of this design is that the cable can easily fall off the lead-out reel during operation. This can lead to scratches or even breakage of the cable, severely impacting product quality, increasing production costs, and posing significant safety hazards.
[0003] The above defects arise because centrifugal force is proportional to the square of the rotational speed and the radius of rotation; as the machine operates at high speed, the centrifugal force increases accordingly. With the rapid rotation of the cantilever and take-up reel, the centrifugal force acts on the cable, attempting to push it away from the center of rotation. Simultaneously, the inconsistent cable tension caused by acceleration and deceleration during machine start-up and shutdown further exacerbates the cable's instability. When the cable falls from the take-up reel, it may come into contact with other machine parts, causing scratches on the cable surface. These scratches weaken the cable's mechanical strength and affect its electrical performance. In more severe cases, the cable may even break, leading to production interruptions, raw material waste, and reduced production efficiency. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a cable guide for the cable forming machine. The cable guide should have the function of preventing the cable from coming out of the cable forming machine and should have the characteristics of simple structure and easy use.
[0005] The technical solution of this utility model is:
[0006] A cable-forming machine lead wheel guide is installed on a cantilever with a lead wheel: characterized in that the guide includes a guide wheel support plate installed at the end of the cantilever, and a plurality of guide wheels hinged and evenly distributed on the guide wheel support plate and arranged corresponding to the lead wheel groove.
[0007] The plurality of guide wheels are arranged sequentially along the same circumferential direction of the output wheel, and a space larger than the diameter of the cable is formed between the groove of each guide wheel and the groove of the output wheel, and the distance between each guide wheel and the output wheel is smaller than the diameter of the cable.
[0008] The guide wheel support plate is a fan-shaped support plate; the fan-shaped support plate is set on the side of the cantilever end and the center of the fan is located on the axis of the lead wheel; the plurality of guide wheels are rotatably positioned on the fan-shaped support plate by means of horizontally arranged guide wheel shafts.
[0009] The guide wheel groove is arranged opposite to the outlet wheel groove.
[0010] The sector radius of the sector-shaped support plate is larger than the radius of the lead-out wheel.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0024] A commonly used cable-making machine (such as...) Figure 3 As shown, it includes a wire feed rod 3, a cantilever 4, a take-up reel 5, and a wire exit wheel 6. The cantilever is fixed to the wire feed rod and driven by the wire feed rod. The three wire exit wheels are rotatably positioned on the cantilever through wire exit wheel shafts 6.3 (the small end of the T-shaped wire exit wheel shaft 6.3 is threaded, and the threaded end passes through the shaft hole of the wire exit wheel and then through the through hole of the cantilever, and is then fixed with a nut). The wire feed rod and the take-up reel rotate in the same direction but at different speeds. While rotating, the take-up reel can reciprocate a preset distance along the axial direction.
[0025] The working principle of the cable forming machine is as follows: the feed rod and the take-up reel rotate in the same direction. The cable passing through the feed rod passes through the three output wheels on the cantilever in sequence, and is orderly wound onto the take-up reel as it rotates. At the same time, the take-up reel moves back and forth along the axial direction, so that the cable is evenly wound onto the take-up reel.
[0026] However, during the start-up and shutdown phases of the cabling machine, the cable on the output reel is subject to sudden changes in centrifugal force and cable tension, making it prone to detaching from the reel, damaging the cable, or even causing serious production accidents. To solve this problem, a cable-keeping device for the output reel of a cabling machine has been designed.
[0027] Figure 1 The cable-forming machine's lead wheel guide device shown includes a guide wheel support plate (preferably a fan-shaped support plate 1) and a guide wheel 2.
[0028] The fan-shaped support plate has three evenly distributed bolt holes on its arc for mounting the guide wheel; a mounting hole is located at the center of the fan-shaped support plate, which is then mounted on the cantilever 4 of the cable forming machine using fixing bolts 6.1. The lead-out wheel on the cantilever, near the take-up reel, experiences the greatest influence from centrifugal force and cable tension, and the probability of cable detachment is also highest at this location; therefore, the cable stopper cooperates with the lead-out wheel near the take-up reel to prevent cable detachment. The fan-shaped support plate is coaxially fixed to the T-shaped end of the lead-out wheel shaft by several fixing bolts 6.1, thereby securing it to the cantilever.
[0029] A fan-shaped cutout is designed in the center of the fan-shaped support plate to reduce the weight of the fan-shaped support plate while ensuring that the structural strength meets the processing requirements.
[0030] The three guide wheels are evenly installed on the arc edge of the sector-shaped support plate, and are hinged by guide wheel shaft 2.2 (the guide wheel shaft end is threaded to mate with the threaded hole on the sector-shaped support plate; such as...). Figure 2As shown), the guide wheel is rotatably positioned on the sector-shaped support plate; the groove 2.1 of the guide wheel is used to block the cable.
[0031] like Figure 3 As shown, the sector-shaped support plate is coaxially connected to the cable-leading wheel 6 of the cable-forming machine on the cantilever 4 (the center of the sector-shaped support plate is located on the axis of the cable-leading wheel). The sector radius of the sector-shaped support plate is larger than the radius of the cable-leading wheel (after installation, there is at least a 1mm gap between the guide wheel and the cable-leading wheel, but smaller than the diameter of the cable); several guide wheels are arranged sequentially along the same circumferential direction of the cable-leading wheel (e.g., ...). Figure 4 As shown, the guide wheel groove 2.1 and the lead wheel groove 6.2 are arranged facing each other, and the axial width of the guide wheel groove is greater than the axial width of the lead wheel, so as to avoid the lead wheel directly contacting the guide wheel and causing interference during the rotation.
[0032] Depend on Figure 3 As can be seen, the cantilever is a forked structure, the line stopper is installed on one side of the fork, and the other side fork 4-1 needs to be equipped with a balance block (conventional technology, the balance block is omitted in the figure) to ensure the dynamic balance of the entire device.
[0033] Nylon is recommended as the material for the guide wheel.
[0034] The working principle of this utility model is as follows:
[0035] The device is installed on the lead-out reel of the existing cable-forming machine.
[0036] When the cabling machine is working, the cable is passed sequentially through the three lead-out wheels 6 on the cantilever 4 and then wound onto the take-up reel 5. During the start-up or stop of the cabling machine, if there is a tension difference between the cable on the lead-out wheels and the cable on the take-up reel, causing the cable to tend to detach from the lead-out wheels, the cable stopper installed on the lead-out wheels will act as a stop to prevent the cable from detaching.
[0037] All components of this utility model embodiment are commercially available.
[0038] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
