Description

Technical Field

[0001] This utility model relates to the field of cable production and testing technology, and in particular to a comparative cable meter. Background Technology

[0002] Cable length counters are core devices used in the wire and cable manufacturing process for real-time measurement of cable length, and their measurement accuracy directly affects product quality and specification consistency. In existing technologies, length counters typically use a measuring wheel or track to contact the cable surface, utilizing friction to drive an encoder or counting device to record the cable's circumference and thus calculate the cumulative length. However, in practical applications, cables are often under tension (e.g., under traction) during measurement, especially for cables with low elastic modulus and high material ductility (e.g., rubber- or plastic-coated cables), which undergo significant elastic deformation under tension. This deformation can lead to relative slippage between the measuring wheel and the cable, or localized compression of the cable, causing the length counter to misjudge the actual running speed and length of the cable.

[0003] When the cable is released from tension, its elastic deformation gradually recovers, and the actual length will be insufficient due to the "false increase" during the measurement stage, ultimately resulting in the actual length of the coiled cable being lower than the nominal value. This problem is particularly prominent in high-speed production lines, not only affecting product qualification rates but also potentially leading to customer complaints and economic losses. Existing meter counters mostly rely on fixed parameter calibration or static tension compensation designs, but they do not offer effective solutions for the dynamic deformation characteristics of elastic materials, making it difficult to adapt to the measurement needs of cables made of different materials. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a comparative cable meter that solves the technical problem that existing cable meter measures cables in a taut state, resulting in the actual length of the coiled cable being lower than the nominal value.

[0005] A comparative cable meter according to an embodiment of the present invention includes an active meter meter and a passive meter meter arranged sequentially.

[0006] The active meter counter includes a mechanical meter counter, a drive motor, and an active wheel connecting the mechanical meter counter and the drive motor. The active wheel has at least two threaded grooves through which cables are wound.

[0007] The passive meter counter includes a mechanical meter counter and a meter counter wheel connected to the mechanical meter counter. A matching wheel is provided on the lower side of the meter counter wheel, and a cable passes through the meter counter wheel and the matching wheel.

[0008] The technical principle of this utility model is as follows: the drive motor drives the drive wheel to rotate, realizing active traction, and the drive wheel is connected to the mechanical meter counter to perform real-time meter counting in the tensioned state. When the cable passes through the drive wheel, the tension disappears due to the active traction of the drive wheel. At this time, it passes through the meter counting wheel for a second meter counting. This is the meter counting in the slack state. Finally, when the cable is rolled up, the meter counting in the slack state shall be used as the standard.

[0009] It should be noted that, due to the structure of the passive meter counter in this application, a tensioning mechanism needs to be added before the subsequent cable winding device to ensure the tension during winding.

[0010] Based on this, by comparing the meter counting difference between the active meter counter and the passive meter counter, the meter count difference under tension and slack conditions can be obtained, thus determining the elastic deformation of the cable. Subsequently, in the production of the same type of cable, a regular meter counter can be used for meter counting, and the meter count difference can be added.

[0011] That is, the comparative cable meter of this application also has the function of measuring the elastic deformation of the cable.

[0012] Compared with the prior art, this utility model has the following beneficial effects: by combining a specific active meter counter with a passive meter counter, it solves the technical problem that the existing cable meter counter measures the cable in a taut state, which may result in the actual length of the coiled cable being lower than the nominal value.

[0013] Furthermore, elastic rubber blocks are provided on both sides of the threaded groove. The bottom of the elastic rubber blocks on both sides transitions to the bottom of the threaded groove with an arc. The top of the elastic rubber blocks on both sides is provided with an arc protrusion. All structures of the elastic rubber blocks on both sides that are close to each other are connected by an arc transition.

[0014] To reduce cable slippage within the threaded groove and ensure the accuracy of the mechanical meter reading.

[0015] Furthermore, the bottom of the threaded groove is arc-shaped, and the arc shape of the bottom of the threaded groove is connected to the arc-shaped elastic rubber blocks on both sides.

[0016] Furthermore, the active meter counter and the passive meter counter share a common support frame.

[0017] Furthermore, the mechanical meter counter includes a counting shaft and a mechanical counting mechanism, with a bevel gear connecting the counting shaft and the mechanical counting mechanism. The counting shaft is connected to a drive wheel or a counting wheel. The counting shaft and the mechanical counting mechanism are respectively mounted on a support frame.

[0018] Furthermore, the passive meter counter is provided with a screw lifting structure, which is mounted on a support frame. The mechanical meter counter and the metering wheel are mounted on the top of the screw lifting structure. The mating wheel is set on the slider of the screw lifting structure. The screw lifting structure drives the mating wheel to move closer to or away from the metering wheel.

[0019] The mating wheels can move up and down to accommodate cables of different diameters.

[0020] Furthermore, the passive meter counter is provided with limiting mechanisms on both sides, and the support frame is provided with a support plate corresponding to the limiting mechanism. The support plate is provided with an elongated hole, and the limiting mechanism includes two rollers, which are respectively installed in the elongated hole by screws.

[0021] Furthermore, the horizontal height through which the cable passes in the active meter counter is higher than the horizontal height through which the cable passes in the passive meter counter.

[0022] Furthermore, the cylindrical surfaces of the measuring wheel and the mating wheel are provided with arc-shaped grooves, and metal plates are provided on both sides of the arc-shaped grooves, with one end of the metal plates connected to the top sidewall of the arc-shaped groove.

[0023] By using a metal plate in conjunction with an arc-shaped groove, there are at least three contact points between the cable and the measuring wheel and the matching wheel, totaling at least six, to prevent the cable from slipping and thus improve the reading accuracy of the mechanical meter counter.

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

[0032] like Figure 1 The comparison cable counter shown includes an active counter 1 and a passive counter 2 arranged in sequence. In front of the active counter 1 are extrusion equipment, cooling equipment, etc., and behind the passive counter 2 is a cable winding device.

[0033] like Figure 1-2 As shown, the active meter counter 1 and the passive meter counter 2 are provided with a common support frame 3 for support.

[0034] The specific active meter counter 1 includes a mechanical meter counter 4, a drive motor 11, and an active wheel 12 connecting the mechanical meter counter 4 and the drive motor 11. The active wheel 12 is provided with at least two threaded grooves 121, through which cables are wound. The cables can be inserted and exited from the upper or lower side of the active wheel 12 depending on the actual situation. If the overall height of the cable production line is high, it is recommended to insert and exit from the upper side, and vice versa.

[0035] The specific passive meter counter 2 includes a mechanical meter counter 4 and a meter counter wheel 21 connected to the mechanical meter counter 4. A matching wheel 22 is provided on the lower side of the meter counter wheel 21. A cable passes through the meter counter wheel 21 and the matching wheel 22. The horizontal height through which the cable passes in the active meter counter 1 is higher than the horizontal height through which the cable passes in the passive meter counter 2, so as to ensure that the cable measured by the passive meter counter 2 will not be tensioned.

[0036] like Figure 2-3 As shown, the mechanical meter counter 4 includes a counting shaft 41 and a mechanical counting mechanism 42, wherein the counting shaft 41 and the mechanical counting mechanism 42 are connected by a bevel gear 43, specifically two bevel gears 43 meshing with each other. The counting shaft 41 is connected to the drive wheel 12 or the counting wheel 21. The counting shaft 41 and the mechanical counting mechanism 42 are respectively mounted on the support frame 3.

[0037] Specifically, the counting shaft 41 and mechanical counting mechanism 42 of the active meter counter 1 are respectively mounted on the support frame 3 by bearings, while the passive meter counter 2 is provided with a screw lifting structure 31. The screw lifting structure 31 is mounted on the support frame 3. The counting shaft 41, mechanical counting mechanism 42 and metering wheel 21 are mounted on the top of the screw lifting structure 31 by bearings. The mating wheel 22 is mounted on the slider of the screw lifting structure 31 by bearings. The screw lifting structure 31 drives the mating wheel 22 to move closer to or away from the metering wheel 21, so that the mating wheel 22 can press the cable tightly on the metering wheel 21 for metering.

[0038] The specific screw lifting structure 31 includes a base and a rotatable screw on the base. The screw is equipped with a slider, and limit rods are provided on both sides of the slider to keep the slider from rotating with the screw, and instead convert the rotation of the screw into linear movement.

[0039] The mechanical counting mechanism 42 can be a meter counter such as the Z96-F model.

[0040] like Figure 2-4 As shown, the passive meter counter 2 is provided with a limiting mechanism 32 on both sides. The support frame 3 is welded and fixed with a support plate 33 corresponding to the limiting mechanism 32. The support plate 33 is provided with an elongated hole 331. The limiting mechanism 32 includes two rollers 321. The two rollers 321 are respectively installed in the elongated hole 331 by screws. Loosening the screws can adjust the distance between the two rollers 321. The rollers 321 are divided into inner and outer layers. The outer layer can rotate with the cable, and the inner layer is connected and fixed with the screws.

[0041] like Figure 5 As shown, elastic rubber blocks 13 are glued to both sides of the threaded groove 121. The bottom of the elastic rubber blocks 13 on both sides transitions to the bottom of the threaded groove 121 with an arc. The top of the elastic rubber blocks 13 on both sides is provided with an arc protrusion 131. All structures of the elastic rubber blocks 13 on both sides that are close to each other are connected by an arc transition.

[0042] Specifically, the bottom of the threaded groove 121 is arc-shaped. The arc shape at the bottom of the threaded groove 121 is connected to the arc shape of the elastic rubber blocks 13 on both sides, which is used to fit the cylindrical shape of the cable. Of course, a flat bottom can also be used, but the fit is not as good as that of the arc shape.

[0043] like Figure 6 As shown, the cylindrical surfaces of the measuring wheel 21 and the mating wheel 22 are provided with arc-shaped grooves 211, and metal plates 212 are provided on both sides of the arc-shaped groove 211. One end of the metal plate 212 is welded to the top side wall of the arc-shaped groove 211 to form two elastic plate structures for clamping the cable, which can allow three contact points between the cable and the measuring wheel 21 or the mating wheel 22.

[0044] When the cable is inserted into the arc-shaped groove 211, it will push open the metal plates 212 on both sides, and the cable will form a contact point with the arc-shaped groove 211 at the bottom, and two contact points with the metal plates 212 on both sides.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
