Abstract
Description
Technical Field

[0038] This embodiment provides a meter counter. Figures 1 to 4 As shown, the meter counter includes a base frame and a meter counter assembly 2, wherein a meter wheel 11 and a pressure wheel 12 are rotatably arranged on the frame 1, and the meter wheel 11 and the pressure wheel 12 are spaced apart along a first direction; the meter counter assembly 2 includes a first roller 21, a second roller 22, a measuring tape 23 and a transmission mechanism 24, the first roller 21 and the second roller 22 are arranged on both sides of the meter wheel 11 along a second direction, and are both rotatably connected to the frame 1, a first end of the measuring tape 23 is wound on the first roller 21, and a second end of the measuring tape 23 is wound on the second roller 22, an identification wheel 231 corresponding to the scale value of the measuring tape 23 is provided on the meter wheel 11, and the transmission mechanism 24 is configured to drive the first roller 21 and the second roller 22 to rotate synchronously with the meter wheel 11 in the same direction.
[0039] In this embodiment, the first direction is perpendicular to the second direction. The first direction is preferably set as the height direction of the meter counter, and the second direction is preferably set as the left and right direction of the meter counter.
[0040] In this embodiment, when the meter counter is in use, the core wire to be measured is inserted between the meter wheel 11 and the pressure wheel 12. The meter wheel 11 and the pressure wheel 12 jointly press the core wire. The meter wheel 11 then rotates to drive the core wire through the gap between the meter wheel 11 and the pressure wheel 12. The transmission mechanism 24 drives the first roller 21 and the second roller 22 to rotate synchronously with the meter wheel 11, causing the measuring tape 23 to gradually unwind from the first roller 21 and gradually rewind on the second roller 22. The length of the unwinding measuring tape 23 is then read by aligning the marking wheel 231 with the scale value on the measuring tape 23. This length corresponds to the length of the core wire. When the measuring tape 23 needs to be reset, the meter wheel 11 rotates in the opposite direction, causing the measuring tape 23 to gradually unwind from the second roller 22 and gradually rewind on the first roller 21 until the measuring tape 23 is fully reset. The meter counter uses a transmission mechanism 24 to link the rotation of the meter wheel 11 with the retraction and extension of the measuring tape 23. The rotation of the meter wheel 11 corresponds to the passing length of the core wire, and the measuring tape 23 can obtain the core wire length in real time during the passing process of the core wire, so that the operator can obtain the core wire length information more intuitively. The structure is simple and more reliable and durable than using electronic components such as rotary encoders and electronic digital displays.
[0041] In this embodiment, the transmission mechanism 24 includes a first pulley 241, a second pulley 242, a third pulley 243, a first transmission belt 244, and a second transmission belt 245. The first pulley 241 is fixed to the first roller 21 and disposed coaxially therewith. The second pulley 242 is fixed to the second roller 22 and disposed coaxially therewith. The third pulley 243 is fixed to the meter wheel 11 and disposed coaxially therewith. The first transmission belt 244 is wound around the first pulley 241 and the third pulley 243. The second transmission belt 245 is wound around the second pulley 242 and the third pulley 243. Specifically, the frame 1 is rotatably provided with a first rotating shaft 111, a second rotating shaft 121, a third rotating shaft 211, and a fourth rotating shaft 221. The meter wheel 11 is mounted on the first rotating shaft 111, the pressure roller 12 is mounted on the second rotating shaft 121, the first roller 21 and the first pulley 241 are both mounted on the third rotating shaft 211, and the second roller 22 and the second pulley 242 are both mounted on the fourth rotating shaft 221. Specifically, the rotation of the meter wheel 11 drives the third pulley 243 to rotate. The rotation of the third pulley 243 simultaneously drives the first pulley 241 and the second pulley 242 to rotate via the first transmission belt 244 and the second transmission belt 245. Furthermore, the rotation of the first pulley 241 drives the first roller 21, and the rotation of the second pulley 242 drives the second roller 22. Consequently, the meter wheel 11, the first roller 21, and the second roller 22 rotate synchronously in the same direction, thereby enabling the rotation of the meter wheel 11 to be linked to the retraction and extension of the measuring tape 23.
[0042] Specifically, in addition to the meter wheel 11, the third pulley 243 and the identification wheel 231 are all mounted on the first rotating shaft 111. This arrangement provides space for the meter wheel 11, the third pulley 243, and the identification wheel 231 to be installed. With these three components positioned together, the rotation of the first rotating shaft 111 simultaneously drives the meter wheel 11, the third pulley 243, and the identification wheel 231 to rotate.
[0043] In some alternative embodiments, the transmission mechanism 24 further includes a first gear, a second gear, a third gear, a fourth gear, and a fifth gear. The first gear is fixed to the meter wheel 11 and coaxially disposed therewith. The second and third gears are both rotatably mounted on the frame 1. The fourth gear is fixed to the first roller 21 and coaxially disposed therewith. The fifth gear is fixed to the second roller 22 and coaxially disposed therewith. The first gear is meshed with the second gear on one side and with the third gear on the other side. The second gear is meshed with the fourth gear, and the third gear is meshed with the fifth gear. Specifically, rotation of the meter wheel 11 drives the first gear, which in turn drives the fourth gear via the second gear, thereby driving the first roller 21. The first gear in turn drives the fifth gear via the third gear, thereby driving the second roller 22. This allows the meter wheel 11, the first roller 21, and the second roller 22 to rotate synchronously in the same direction, enabling the rotation of the meter wheel 11 to be linked to the retraction and extension of the measuring tape 23.
[0044] In some other optional embodiments, the transmission mechanism 24 further includes a first motor, a second motor, and a third motor, all of which are disposed on the frame 1. The first roller 21 is disposed on the output shaft of the first motor, the second roller 22 is disposed on the output shaft of the second motor, and the meter wheel 11 is disposed on the output shaft of the third motor. By controlling the first, second, and third motors to rotate in the same direction and at the same speed, the meter wheel 11, the first roller 21, and the second roller 22 can also be synchronously rotated in the same direction, thereby achieving linkage between the rotation of the meter wheel 11 and the retraction and extension of the measuring tape 23.
[0045] In this embodiment, the axes of the first roller 21, the meter wheel 11, and the second roller 22 are arranged parallel to each other along the third direction. In this embodiment, the first, second, and third directions are orthogonal to each other, with the third direction preferably being the front-to-back direction of the meter counter. This arrangement allows the tape measure 23 to extend along the second direction and be tensioned on the first and second rollers 21, 22 without bending, facilitating the retraction and extension of the tape measure 23 and ensuring that the marking wheel 231 corresponds to the scale of the tape measure 23.
[0046] In this embodiment, fixed blocks 17 are provided on opposite sides of the frame 1 along the second direction. One of the fixed blocks 17 is provided with a first roller 21, and the other fixed block 17 is provided with a second roller 22. The provision of the fixed blocks 17 provides a secure installation space for the first roller 21 and the second roller 22.
[0047] In this embodiment, the marking wheel 231 is provided with stopper protrusions 232 at opposite ends along its axial direction, and the measuring tape 23 is positioned between the two stopper protrusions 232. The stopper protrusions 232 limit the position of the measuring tape 23 in the first direction, ensuring that the position of the measuring tape 23 relative to the marking wheel 231 is stable and reliable, without any deviation.
[0048] In this embodiment, the meter counter further includes a movable plate 13 and a drive member. The pressure wheel 12 is rotatably connected to the movable plate 13. The drive member is configured to drive the movable plate 13 to move relative to the frame 1 in a first direction, thereby causing the pressure wheel 12 to approach or move away from the meter wheel 11 in the first direction. Driven by the drive member, the movable plate 13 can move relative to the frame 1 in the first direction, thereby adjusting the spacing between the pressure wheel 12 and the meter wheel 11 in the first direction. This allows the meter counter to accommodate core wires of varying diameters, further enhancing its compatibility.
[0049] In this embodiment, the driving member includes a screw 14 and a handle 15. The screw 14 is rotatably connected to the frame 1 and extends in a first direction. The screw 14 is threadedly connected to the movable plate 13. One end of the screw 14 passes through the frame 1 and is connected to the handle 15. Specifically, a lead screw thread structure is formed between the screw 14 and the movable plate 13. When the operator rotates the handle 15, the screw 14 rotates, thereby achieving movement of the movable plate 13 in the first direction relative to the frame 1.
[0050] In some other optional embodiments, the driving member also includes a telescopic cylinder, the cylinder body of the telescopic cylinder is fixed on the frame 1, the cylinder rod of the telescopic rod is fixed on the movable plate 13, and the cylinder rod of the telescopic cylinder is telescoped relative to the cylinder body, thereby enabling the movable plate 13 to move relative to the frame 1.
[0051] Specifically, a guide rod 16 is provided on the frame 1 extending in the first direction, and the movable plate 13 passes through the guide rod 16 and is slidably connected to the guide rod 16. When the screw 14 rotates, the movable plate 13 is driven by the screw 14 to slide relative to the guide rod 16, so that the movable plate 13 moves relative to the frame 1 strictly along the first direction.
[0052] Specifically, a support plate 19 is provided on the frame 1, the screw rod 14 passes through the support plate 19, and the guide rod 16 is fixedly connected to the support plate 19. The provision of the support plate 19 can provide a reliable installation space for the guide rod 16.
[0053] In this embodiment, a guide assembly 3 is provided on opposite sides of the frame 1 along the second direction. The guide assembly 3 includes a first guide rod 31 and a second guide rod 32, arranged in pairs. The two first guide rods 31 are spaced apart along the first direction, and the two second guide rods 32 are spaced apart along the third direction. A first gap formed between the two first guide rods 31, and a second gap formed between the two second guide rods 32, are both used for threading a core wire. The spacing between the two first guide rods 31 and the spacing between the two second guide rods 32 are adjustable. The first gap formed between the two first guide rods 31 and the second gap formed between the two second guide rods 32 allow the core wire to pass through the first and second gaps. In this embodiment, the spacing between the two first guide rods 31 and the spacing between the two second guide rods 32 can be adjusted along the first direction, and the spacing between the two second guide rods 32 can be adjusted along the third direction. This arrangement allows the lengths of the first and second gaps to be adjusted, defining the threading position of the core wire, ensuring that the measured core wire can pass smoothly and accurately through the meter, maintaining linear motion, and reducing measurement errors, thereby achieving accurate measurement of the core wire length.
[0054] Specifically, a first auxiliary wheel 311 is rotatably mounted on the first guide rod 31 and is coaxially arranged with the first guide rod 31. A second auxiliary wheel 321 is rotatably mounted on the second guide rod 32 and is coaxially arranged with the second guide rod 32. By providing the first auxiliary wheel 311, when the core wire is threaded through the two first guide rods 31, the two first auxiliary wheels 311 roll in contact with the core wire surface. When the core wire is threaded through the two second guide rods 32, the two second auxiliary wheels 321 roll in contact with the core wire surface, thereby preventing factors such as friction from adversely affecting the threading of the core wire.
[0055] Specifically, the frame 1 has a first elongated hole 101 and a second elongated hole 181 on opposite sides along the second direction. The length of the first elongated hole 101 is parallel to the first direction, and the first guide rod 31 slides through the first elongated hole 101 and is secured to the first elongated hole 101 by a first screw 331. The length of the second elongated hole 181 is parallel to the third direction, and the second guide rod 32 slides through the second elongated hole 181 and is secured to the second elongated hole 181 by a second screw 332. Specifically, the first guide rods 31 on both sides of the same side slide within the first elongated hole 101 to adjust the spacing between them along the first direction. Once the spacing is adjusted to the desired spacing, the first guide rods 31 are locked by screwing in the first screw 331, securing the adjusted position of the first guide rods 31. The second guide rods 32 on both sides of the same side slide in the second long hole 181 to adjust the distance between each other along the second direction. When the distance is adjusted to the right position, the second guide rods 32 are locked by screwing in the second screws 332 to achieve the fixation of the second guide rods 32 after the position adjustment.
[0056] In this embodiment, the second long hole 181 is formed on the connecting plate 18 on the corresponding side.
[0057] In this embodiment, a bracket 4 is fixedly provided below the frame 1. The bracket 4 provides a stable installation position for the frame 1 of the meter counter, ensuring that it remains stable during the measurement process without shaking or shifting.
