[0022] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. The accompanying drawings provide 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 in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0023] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0024] For the description of the present utility model, non-limiting Figure 1 The marks "front", "rear", "up", "down", "left" and "right" shown in the figure are used to facilitate understanding of the embodiment and are not intended to limit the present invention. Among them, the front-to-back direction represents the horizontal direction, the left-right direction represents the longitudinal direction, and the up-down direction represents the vertical direction.

[0025] Figure 1-Figure 6 The utility model shows an embodiment of a cable measuring mechanism 001 and a wire stripping machine 01, such as Figure 1 As shown, the cable measuring mechanism 001 includes a transmission wheel assembly 1, a measuring wheel assembly 2 and an encoder 3. The transmission wheel assembly 1 is arranged near the feeding end of the feeding conveyor 002 and fixed on the side plate of the lower fixed seat of the feeding conveyor 002. The measuring wheel assembly 2 is correspondingly arranged on the upper side of the transmission wheel assembly 1 and arranged on the side plate of the upper fixed seat of the feeding conveyor 002. The rotating shaft of the encoder 3 is connected to the measuring wheel assembly 2; the cable passes between the measuring wheel assembly 2 and the transmission wheel assembly 1 and is closely attached to the measuring wheel assembly 2 and the transmission wheel assembly 1.

[0026] Among them, the transmission wheel assembly 1 rotates synchronously with the feeding conveyor 002. The transmission wheel assembly 1 transmits the cable to the feeding conveyor 002. Since the cable is close to the measuring wheel assembly 2 and the transmission wheel assembly 1 at the same time, the cable will drive the measuring wheel assembly 2 to rotate. The rotating shaft of the encoder 3 is connected to the measuring wheel assembly 2, and the number of rotations can be counted and then converted into the length of the cable.

[0027] In this embodiment, the transmission wheel assembly 1 and the feeding conveyor device 002 rotate synchronously, which can prevent the cable from sliding back and forth on the transmission wheel assembly 1 and causing errors in the measured length, thereby improving the accuracy of the measurement.

[0028] like Figure 2 As shown, in some embodiments, a fixing plate 21 is provided on the side of the upper fixing seat of the feeding conveying device 002, and a linear guide rail 211 is vertically provided on the fixing plate 21. The measuring wheel 24 assembly includes a connecting block 22, and a slide groove 221 corresponding to the linear guide rail 211 is provided on the connecting block 22. The slide groove 221 is stuck on the linear guide rail 211, and the measuring wheel assembly 2 can slide vertically along the linear guide rail 211. Accordingly, sufficient space can be reserved by sliding the measuring wheel assembly 2 to perform initial lead-in of the cable, and it can also be suitable for measuring cables of different diameters. The cable is pressed under the action of its own gravity to prevent the cable from slipping, thereby ensuring the accuracy of the measurement.

[0029] In some embodiments, a limit baffle 23 is provided on the fixed plate 21, one end of the limit baffle 23 is fixed to the upper part of the fixed plate 21, in this embodiment, one end of the limit baffle 23 is fixed to the upper end surface of the fixed plate 21, and the other end extends outward to the upper side of the measuring wheel assembly 2, and a guide column 231 extending downward is fixed on the limit baffle 23, and an elastic member 232 is sleeved on the guide column 231, and the lower end of the elastic member 232 abuts against the measuring wheel assembly 2. In this embodiment, the elastic member 232 is a spring, and the guide column 231 can guide the spring to avoid the spring from being skewed when the spring is squeezed, resulting in unstable force on the measuring wheel assembly 2. Through the elastic force of the spring, the measuring wheel assembly 2 can be made closer to the cable to avoid slipping during measurement, thereby ensuring the accuracy of the measurement.

[0030] It should be understood that the elastic member 232 may also be other elastic objects sleeved on the guide column 231 to squeeze the measuring wheel assembly 2, such as a rubber elastic tube, which is not limited here.

[0031] In some embodiments, two linear guide rails 211 are provided on the fixed plate 21, and two slide grooves 221 are correspondingly provided on the connecting block 22, so that the process of the measuring wheel assembly 2 moving up and down is more stable. Two groups of guide posts 231 and elastic members 232 are provided on the limit baffle 23, and the two groups of guide posts 231 and elastic members 232 can be evenly distributed on the limit baffle 23. When the elastic member 232 contacts the measuring wheel assembly 2, the measuring wheel assembly 2 is subjected to a more uniform force, and the effect can also be more obvious. It should be understood that the linear guide rails 211 and the slide grooves 221 can also be fewer or more groups, and the guide posts 231 and the elastic members 232 can also be fewer or more groups, and there is no limitation on this here.

[0032] like Figure 3 As shown, in some embodiments, the cable measuring mechanism 001 includes a transmission connection member 4, which connects the transmission wheel assembly 1 and the motor synchronous wheel 41 of the feeding conveyor 002. In this embodiment, the transmission connection member 4 is a belt, through which the transmission wheel assembly 1 and the feeding conveyor 002 can share a driving motor, that is, the same speed rotation is achieved and the cost is saved. It should be understood that the transmission connection member 4 can also be a chain, which is not limited here.

[0033] like Figure 4 As shown, in some embodiments, the transmission wheel assembly 1 includes a transmission wheel 11, a transmission shaft 12, a transmission fixed block 13 and a transmission synchronous wheel 14. The transmission fixed block 13 is fixed to the side of the lower fixed seat. The transmission shaft 12 is rotatably arranged in the transmission fixed block 13, and both ends of the transmission shaft 12 are exposed outside the transmission fixed block 13. The transmission wheel 11 is arranged at one end of the transmission shaft 12, and the transmission wheel 11 is kept flush with the conveyor belt of the feeding conveyor device 002. The transmission synchronous wheel 14 is arranged at the other end of the transmission shaft 12. The transmission synchronous wheel 14 and the motor synchronous wheel 41 are located on the same side, and the belt is wrapped around the transmission synchronous wheel 14 and the motor synchronous wheel 41. Among them, when the driving motor of the feeding conveyor device 002 rotates, it drives the transmission synchronous wheel 14 to rotate through the belt, and then drives the transmission wheel 11 to rotate synchronously through the transmission shaft 12.

[0034] In some embodiments, a limiting groove 111 is provided on the wheel surface of the transmission wheel 11 along the circumferential direction. In this embodiment, two intersecting bevel surfaces form the limiting groove 111, and the cable can be placed in the limiting groove 111. During the cable movement measurement, the limiting groove 111 can limit the cable and prevent it from shaking left and right, thereby improving the measurement stability.

[0035] In some embodiments, the measuring wheel assembly 2 includes a measuring wheel 24, a measuring shaft 25 and a measuring fixed block 26. The measuring fixed block 26 is adjacent to a side fixed connection block 22 of the upper fixed seat. The connection block 22 is slidably set on the fixed plate 21. The measuring shaft 25 is rotatably passed through the measuring fixed block 26, and both ends of the measuring fixed block 26 are exposed. The measuring wheel 24 is set at one end of the measuring shaft 25, and the rotating shaft of the encoder 3 is set at the other end of the measuring shaft 25. When the measuring wheel 24 rotates, it can drive the rotating shaft of the encoder 3 to rotate synchronously. The encoder 3 counts the number of rotations, and then converts it into the length of the cable through the circumference of the measuring wheel 24.

[0036] In some embodiments, a rubber anti-slip sleeve is also provided on the circumference of the measuring wheel, and the rubber anti-slip sleeve is used to prevent the cable from slipping. In addition, the rubber anti-slip sleeve is a rough surface with textures, which can increase the friction between the cable and the rubber anti-slip sleeve and further enhance the anti-slip property.

[0037] like Figure 5 As shown, in some embodiments, the measuring wheel assembly 2 includes an encoder reinforcement frame 27, the encoder reinforcement frame 27 includes a reinforcement plate 271 and three connecting columns 272, one end of the connecting column 272 is fixed to the reinforcement plate 271, and the other end is fixed to the measuring fixed block 26, the three connecting columns 272 are arranged around the rotating shaft of the encoder 3, and do not affect the rotation of the rotating shaft of the encoder 3, the encoder 3 is fixed on the reinforcement plate 271, and the encoder reinforcement frame 27 can fix the encoder 3 more firmly on the measuring fixed block 26. It should be understood that the encoder reinforcement frame 27 can include more or fewer connecting columns 272, and there is no limitation here.

[0038] like Figure 6 As shown, based on the same inventive concept, the utility model also provides a wire stripping machine 01, including the above-mentioned cable measuring mechanism 001. When stripping the cable, the cable measuring mechanism 001 measures the length of the cable and transports the cable to the feeding conveyor 002. Then the feeding conveyor 002 sends the cable to the mobile cutter mechanism 003. The mobile cutter mechanism 003 cuts the cable into a specific length and strips it. Finally, the cable is output through the discharging conveyor 004.

[0039] It can be seen that the utility model discloses a cable measuring mechanism and a wire stripping machine. The cable measuring mechanism keeps synchronous rotation with the feeding conveyor through the transmission wheel assembly, which can avoid the cable sliding back and forth on the transmission wheel assembly, causing errors in the measured length, thereby improving the measurement accuracy. By arranging slide grooves, linear guide rails and elastic parts, the measuring wheel assembly can be closer to the cable, further improving the measurement accuracy.

[0040] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention.
