The accuracy of the meter counter will directly affect the accuracy of the quantitative packaging cable measurement. It also represents the overall quality of a company and the level of production and process equipment. It is also a key equipment for controlling production costs and quality.

[0003] During the use of existing cable meter, due to the influence of the pay-out tension of the measured cable or the occasional failure of the clamping wheel, the measuring wheel may sometimes produce a slight reversal during the production process, thereby affecting the accuracy of the length measurement of the measured cable, and failing to timely and accurately track the length of the cable during the production process, thereby increasing the manufacturing cost of the cable. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned technical problems. The utility model provides an anti-reversal meter cable measuring wheel. By adopting the device, the slight reversal of the measuring wheel sometimes produced in the production process can be avoided, the accuracy of the length measurement of the measured cable is ensured, the length of the cable in the production process is tracked in time and accurately, and the manufacturing cost of the cable is effectively reduced.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical scheme: an anti-reversal meter cable measuring wheel, comprising: a measuring wheel body; two one-way bearings, both of which are installed on the inner ring of the measuring wheel body; a measuring wheel axle, which is installed through the inner rings of the two one-way bearings; two shaft elastic retaining rings, both of which are fitted with the measuring wheel axle and are respectively located on the opposite sides of the two one-way bearings; a transmission gear, which is installed on one side of the measuring wheel body, and the axial geometric center line of the transmission gear coincides with that of the measuring wheel body.

[0006] In order to facilitate the installation and disassembly of the various parts of the measuring wheel, as a preferred anti-reversal meter cable measuring wheel of the utility model, the inner ring of the one-way bearing is provided with a keyway 1, the surface of the measuring wheel shaft is provided with a keyway 2, and a flat key is movably connected between the keyway 1 and the keyway 2.

[0007] In order to fasten the transmission gear to the measuring wheel, as a preferred embodiment of the utility model of an anti-reversal meter cable measuring wheel, a plurality of screws are installed through between the measuring wheel shaft and the transmission gear, and the screws are specifically hexagon socket head screws.

[0008] In order to ensure that the axial geometric center lines of the transmission gear and the measuring wheel are completely coincident, as a preferred anti-reversal meter cable measuring wheel of the utility model, a groove is provided on one side of the measuring wheel body, and a boss matching the groove is fixed on one side of the transmission gear close to the measuring wheel body, the groove and the boss are both annular structures, and the axial geometric center lines of the groove, the boss and the measuring wheel body coincide.

[0009] The beneficial effects of the utility model are as follows:

[0010] By installing two sets of one-way bearings between the measuring wheel body and the measuring wheel axle, the measuring wheel can only roll in one direction, and will generate great resistance in the other direction, thereby avoiding the measuring wheel from slightly reversing in the opposite direction of the measured cable. At the same time, since the use of one-way bearings can effectively prevent the measuring wheel from reversing, the meter counter does not need to design a separate anti-reversal mechanical mechanism, which can save a lot of manufacturing costs.

The one-way bearing 2 is a kind of bearing that can rotate freely in one direction and is locked in the other direction. By installing two sets of one-way bearings 2 between the measuring wheel body 1 and the measuring wheel shaft 3, the measuring wheel can only roll in one direction, and a large resistance will be generated in the other direction, thereby preventing the measuring wheel from slightly reversing in the opposite direction of the measured cable. At the same time, since the use of the one-way bearing 2 can effectively prevent the measuring wheel from reversing, the meter counter does not need to design a separate anti-reversal mechanical mechanism, which can save a lot of manufacturing costs.

[0019] A measuring wheel shaft 3, which is installed through the inner rings of two one-way bearings 2;
