Description

Technical Field

[0001] This utility model relates to the field of length measurement technology, and in particular to a meter counter. Background Technology

[0002] During cable processing, cable length needs to be measured. In existing technology, a length counter is used to measure cable length. This length counter measures the length of the cable as it rolls around it. It consists of a measuring wheel, a graduated disc, a photoelectric encoder, and a digital processing unit. Through manual or machine traction, the moving cable drives the measuring wheel to rotate. The rotation angle of the graduated disc, coaxial with the measuring wheel, is detected by the photoelectric encoder. The signal processor converts the signal, automatically measuring the cable length by the rotation angle of the graduated disc, and accurately displays the value on a monitor. However, during use, the cable being transported by the length counter is affected by tension during product manufacturing. During cable changes or pauses, the guide wheel may experience inertia due to the traction machine, causing the cable to slip off the wheel. The cable may also be affected by external forces on the edge of the wheel, resulting in surface damage and product scrap.

[0003] For example, the patent with publication number CN211527328U discloses a protective shell for a meter counter and a meter counter. The protective shell is set on the outside of the reel of the meter counter to prevent the cable from slipping off the reel and damaging the surface of the cable during the measurement process, and at the same time to ensure that the cable is transported in the normal position. However, in actual use, it is found that the setting of the protective shell hinders the normal transmission of the cable to a certain extent, and the cable will come into contact with the side opening on the shell, causing friction damage to the cable. Utility Model Content

[0004] To address the issue that the protective casing of existing meter counters restricts normal cable transmission, this invention provides a meter counter that protects both the measuring wheel and the guide wheel by a protective bracket fixedly installed outside the counter. Furthermore, a spring is installed between the mounting bracket and the protective bracket, and the elastic force ensures that the measuring wheel on the protective bracket remains in close contact with the cable, guaranteeing accurate meter counting.

[0005] This utility model provides a meter counter, including a counter and a measuring wheel, and a protective bracket. The measuring wheel is disposed at one end of the protective bracket, and the axle of the measuring wheel passes through the protective bracket and is fixedly connected to the counter. A guide wheel is disposed at the other end of the protective bracket. A rotating shaft for mounting the guide wheel is fixedly disposed on the protective bracket, and mounting brackets are disposed at both ends of the rotating shaft at an angle to the protective bracket for connecting the meter counter to an external winding device. The protective bracket protects the measuring wheel and the guide wheel, and the protective bracket is fixedly connected to the counter as a whole through the axle. The meter counter as a whole is connected to the external winding device through the mounting brackets.

[0006] Furthermore, a tension spring is installed between the angled protective bracket and the mounting bracket to provide a pulling force that causes the protective bracket to rotate towards the mounting bracket. One end of the tension spring is fixed to the bottom of the mounting bracket, and the other end is fixed to the protective bracket near the measuring wheel. The elastic force of the tension spring ensures that the measuring wheel always has a pulling force towards the cable, allowing for close contact with the cable and improving measurement accuracy.

[0007] Furthermore, a torsion spring is provided at the end of the rotating shaft. One end of the torsion spring is fixed to the rotating shaft, and the other end is fixed to the protective bracket near the guide wheel. The elastic force of the torsion spring ensures that the measuring wheel always has a pulling force towards the cable, allowing for close contact with the cable and improving measurement accuracy.

[0008] Furthermore, a limit block is provided at one end of the torsion spring fixed to the protective bracket, and several limit holes adapted to the limit block are correspondingly opened on the protective bracket. The limit holes are circumferentially opened along the rotation direction of the torsion spring. By inserting the limit block at the end of the torsion spring into the limit holes at different positions, the initial included angle between the mounting bracket and the protective bracket can be adjusted.

[0009] Furthermore, several positioning rods are installed between the protective bracket and the counter. Each positioning rod has a locking hole at both ends, and the positioning rods are fixed between the protective bracket and the counter by pins. These positioning rods cooperate with the wheel axle to ensure the connection stability between the protective bracket and the counter.

[0010] Furthermore, the mounting bracket is connected to the support rod of the external winding device via a double-ended screw. The bottom of the mounting bracket has a screw hole adapted to the double-ended screw. One end of the double-ended screw is screwed onto the support rod, and the other end connects to the screw hole. The meter counter is then installed on the desired winding device using the screw.

[0011] Furthermore, the double-ended screw is equipped with two locking nuts, which abut against the bottom of the mounting bracket and the top of the support rod, respectively. These locking nuts can be used to lock the meter counter in its mounting position.

[0012] Furthermore, a sensor (such as a photoelectric sensor, Hall sensor, or encoder) is installed on the axle of the measuring wheel that is fixedly connected to the counter to convert the mechanical rotation of the measuring wheel into an electrical signal. The counter is equipped with an electronic control unit for receiving and processing the electrical signals sent by the sensor. The electrical signals generated by the sensor are transmitted to the electronic control unit (ECU) through wires. The counter is also equipped with a battery compartment for power supply. Both the sensor and the ECU are electrically connected to the battery compartment through wires.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model provides a meter counter that uses a protective bracket to protect the measuring wheel and guide wheel, effectively preventing the cable from slipping off the measuring wheel without damaging it. The mounting bracket also allows for easy installation of the meter counter on a desired cable winding device. An elastic element between the protective bracket and the mounting bracket ensures the measuring wheel is constantly pulled towards the cable, maintaining close contact and improving measurement accuracy. Furthermore, the protective bracket design considers smooth cable passage, preventing damage caused by excessive friction or compression, further ensuring cable integrity. The precise guidance of the guide wheel allows the cable to pass smoothly and orderly through the measurement area, reducing swaying and jumping during transmission, further enhancing measurement stability and accuracy.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0022] To prevent the cable from slipping off the measuring wheel while ensuring its smooth passage without causing wear, a meter counter is designed, such as... Figure 1As shown, the device includes a counter 1, a measuring wheel 2, and a protective bracket 3. The measuring wheel 2 is located at one end of the protective bracket 3, and its axle 21 passes through the protective bracket 3 and is fixedly connected to the counter 1. A guide wheel 4 is located at the other end of the protective bracket 3. A rotating shaft for mounting the guide wheel 4 is fixedly mounted on the protective bracket 3. Mounting brackets 5, angled to the protective bracket 3, are also located at both ends of the rotating shaft for connecting the meter counter to an external winding device. The cable passes through the guide wheel 4 from above and exits from below the measuring wheel 2. The protective bracket 3 and the mounting brackets 5 are connected by an elastic element at an angle. The elastic element provides a pulling force to the protective bracket 3, ensuring that the measuring wheel 2 on the protective bracket 3 always contacts the cable, thereby improving measurement accuracy.

[0023] Connecting the protective bracket 3 and the counter 1 solely through the axle 21 of the measuring wheel 2 may not be stable enough. To further strengthen the connection, several positioning rods 10 are set between the protective bracket 3 and the counter 1. Each positioning rod 10 has a locking hole at both ends. The positioning rods 10 are fixed between the protective bracket 3 and the counter 1 by pins. Generally, three positioning rods are set, and the three positioning rods 10 are distributed and supported between the protective bracket 3 and the counter 1, so that the protective bracket 3 and the counter 1 form a stable and connected whole.

[0024] The meter counter can be fixed to an external winding device, such as a cable reel, which has an outer frame. A support rod 12 for mounting the meter counter is fixed to the outer frame. A mounting bracket 5 is connected to the support rod 12 via a double-ended screw 11. The bottom of the mounting bracket 5 has a screw hole adapted to the double-ended screw 11. One end of the double-ended screw 11 is screwed onto the support rod 12, and the other end is connected to the screw hole. Two locking nuts 13 are also provided on the double-ended screw 11, which abut against the bottom of the mounting bracket 5 and the top of the support rod 12, respectively. The upper locking nut 13 is used to lock the screw position at the end of the mounting bracket 5, and the lower locking nut 13 is used to lock the screw position at the end of the support rod 12.

[0025] A sensor is mounted on the axle 21 of the measuring wheel 2, which is fixedly connected to the counter 1. The counter 1 contains an electronic control unit for receiving and processing the electrical signals transmitted by the sensor, and also a battery compartment for power supply. The electronic control unit is a microcontroller, such as the STC89C52. The sensor can be any one of a photoelectric sensor, a Hall effect sensor, or an encoder, specifically an E6B2-CWZ6C incremental rotary encoder. Converting the rotation of the measuring wheel 2 into an electrical signal output to the electronic control unit via an encoder is a mature technology in this field and will not be elaborated upon here.

[0026] like Figure 2 and 3As shown, in order to provide a persistent pulling force to the measuring wheel 2 towards the cable side, in Embodiment 1, a tension spring 6 is provided between the protective bracket 3 and the mounting bracket 5, which are set at an angle, to provide a pulling force to the protective bracket 3 to rotate towards the mounting bracket 5. One end of the tension spring 6 is fixed to the bottom of the mounting bracket 5, and the other end of the tension spring 6 is fixed to the protective bracket 3 near the measuring wheel 2.

[0027] like Figure 4 As shown in Embodiment 2, a torsion spring 7 is provided at the end of the rotating shaft. One end of the torsion spring 7 is fixed to the rotating shaft, and the other end is fixed to the protective bracket 3 near the guide wheel 4. A limit block 8 is provided at one end of the torsion spring 7 fixed to the protective bracket 3. Several limit holes 9 are correspondingly provided on the protective bracket 3 to match the limit block 8. The limit holes 9 are circumferentially opened along the rotation direction of the torsion spring 7. The limit block 8 can be inserted into any one of the limit holes 9. After adjusting the initial angle of the protective bracket 3 and the mounting bracket 5, the limit block 8 is inserted into the corresponding limit hole 9, and the initial angle of the protective bracket 3 can be adjusted according to the cable specifications.

[0028] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
