Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a double meter measuring device for galvanized steel strand. Background Technology

[0002] A cable length counter is an instrument used to measure cable length. It typically uses rollers or sensors to detect cable movement and thus calculate the length. Specifically, the moving cable comes into direct contact with the roller, and the friction between the cable and the roller causes the roller to rotate. The number of rotations of the roller is detected by a sensor to obtain the cable length data.

[0003] In the metering process for galvanized steel strand, the strand will sway to some extent during operation, which may cause it to not contact the rollers. This results in a metered length that is less than the actual length of the strand, leading to monitoring errors. The galvanized steel strand is coated with zinc. During contact and friction with the rollers, wear occurs, causing zinc powder to detach. Hard particles in the zinc powder, if adhering to the roller surface, will accelerate wear. Furthermore, if zinc powder accumulates on the roller surface, it may reduce the friction between the strand and the roller, causing slippage—that is, relative sliding between the roller and the strand—and reducing the accuracy of the metering. Summary of the Invention

[0004] To address the problem of slippage in conventional metering devices, which reduces the accuracy of metering data, this invention provides a dual metering device for galvanized steel strands. It uses two closely spaced metering wheels to elastically clamp the steel strand, making it suitable for metering steel strands of different diameters. It can also clean and collect any loose zinc powder, and the elastic clamping prevents slippage. Combined with both mechanical and sensor-based metering methods, it ensures the accuracy of the metering data.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A double meter counting device for galvanized steel strand includes a lifting mechanism, a meter counting platform, a guide unit, and a meter counting unit. The lifting mechanism is arranged vertically, and the meter counting platform is set above the lifting mechanism to facilitate the vertical movement of the meter counting platform. The meter counting platform is arranged horizontally.

[0007] The guide units are arranged at intervals on both sides of the metering platform, and the metering unit is arranged in the middle of the metering platform. The steel strand is threaded between the guide units and the metering unit. The guide units facilitate the accurate introduction and exit of the steel strand into the metering unit.

[0008] The meter counting unit includes a slide rail, an adsorption frame, a meter counting wheel, and a counter. The adsorption frames are elastically slidably connected to both ends of the slide rail to facilitate the sliding of the adsorption frames. The two adsorption frames tend to be close together, and the meter counting wheel is rotatably arranged in each adsorption frame. The two meter counting wheels are close to each other, and the line connecting the two meter counting wheels is perpendicular to the line connecting the two guide units. The two meter counting wheels elastically clamp the steel strand to ensure a tight fit with the steel strand and avoid slippage.

[0009] Each of the adsorption frames is connected to an exhaust fan on both sides via an air pipe. The adsorption frame includes a frame body, a soft brush frame, and an adsorption cover. The soft brush frame is arranged around the inside of the frame body and contacts the surface of the measuring wheel to facilitate the cleaning of zinc powder on the surface of the measuring wheel. The adsorption cover is arranged on both sides of the frame body. One end of the adsorption cover is enlarged and faces the measuring wheel, while the other end of the adsorption cover is narrowed and connected to the exhaust fan via an air pipe to facilitate the suction away of the cleaned zinc powder.

[0010] Each adsorption frame is equipped with a counter, which is connected to a measuring wheel inside the adsorption frame. The counter is one or a combination of mechanical and electronic counters, which facilitates monitoring the number of rotations of the measuring wheel and obtaining the length of the steel strand.

[0011] Furthermore, the lifting mechanism includes a base plate, a telescopic rod, and a reinforcing plate. The telescopic rod is arranged vertically at the center of the base plate. The reinforcing plate is arranged between the bottom of the telescopic rod and the base plate. The number of reinforcing plates is multiple and evenly distributed in a circumferential direction, which improves the reliability of the telescopic rod installation.

[0012] Furthermore, the telescopic rod includes a lower cylinder, an upper column, and a handwheel. The lower cylinder is fixedly connected to the base plate, and the reinforcing plate is arranged between the lower cylinder and the base plate. The upper column is inserted inside the lower cylinder. The upper column is a screw rod structure. The upper end of the upper column extends out of the lower cylinder and is connected to the metering platform to facilitate the support of the metering platform.

[0013] The lower cylinder is rotatably connected to the handwheel at its upper end. The handwheel is sleeved on the outside of the upper column and threadedly connected to the upper column. Limiting bolts are also provided on both sides of the lower cylinder, and limiting grooves are opened on both sides of the upper column. The limiting bolts and limiting grooves correspond one-to-one. The corresponding limiting bolts pass through the lower cylinder and are inserted into the limiting grooves to restrict the rotation of the upper column.

[0014] Furthermore, the guiding units on both sides are symmetrically arranged. Each guiding unit includes a vertical guide roller and a horizontal guide roller. The number of vertical guide rollers is two arranged at intervals to facilitate limiting the left and right swaying of the steel strand. The vertical guide rollers are arranged vertically and are far away from the meter counting unit. Each vertical guide roller includes a roller shaft and a roller body. The roller shaft passes through the roller body and the roller shaft and roller body are rotatably connected.

[0015] The horizontal guide roller and the vertical guide roller have the same structure. The horizontal guide roller is arranged horizontally and is close to the meter counting unit. The length of the horizontal guide roller is greater than the center distance between the two vertical guide rollers.

[0016] Furthermore, the metering platform has an elongated hole, with vertical guide rollers arranged on both sides of the hole. The roller shafts of the vertical guide rollers pass downward through the elongated hole and are connected to nuts, which facilitates the installation and position adjustment of the vertical guide rollers. The metering platform is also equipped with two mounting brackets, each with a height adjustment hole. The roller shafts of the horizontal guide rollers extend from the two height adjustment holes at both ends and are connected to nuts, which facilitates the installation and position adjustment of the horizontal guide rollers.

[0017] Furthermore, the slide rail is fixedly connected to the metering platform, and the slide rail is arranged perpendicular to the running direction of the steel strand. A slider is provided at the bottom of the adsorption frame, and the adsorption frame is slidably connected to the slide rail through the slider, which improves the smoothness of the adsorption frame sliding.

[0018] A tension spring assembly is also provided between each adsorption frame and the measuring platform. Two tension spring assemblies are arranged parallel to each other on both sides of the slide rail. Each tension spring assembly includes a tension spring body arranged in a straight line, a mounting bolt one, and a mounting bolt two. Mounting bolt one connects upward to the adsorption frame, and mounting bolt two connects downward to the measuring platform. There is a gap between mounting bolt one and mounting bolt two. The two ends of the tension spring body are hooked onto mounting bolt one and mounting bolt two, respectively. The tension spring assembly causes the two measuring wheels to move closer together.

[0019] Furthermore, the diameter of the measuring wheel is larger than the width of the adsorption frame, and limit sections are arranged at both the upper and lower ends of the measuring wheel. The diameter of the limit sections is larger than the diameter of the measuring wheel, which facilitates limiting the up-and-down swaying of the steel strand. Both the measuring wheel and the limit sections are wheel bodies made of metal.

[0020] Furthermore, the counter is a combination of a mechanical counter and an electronic counter. A gear set is provided between the input shaft of the mechanical counter and the measuring wheel. The gear set consists of two meshing bevel gears. A protective shell is also provided on the adsorption frame, and the gear set is arranged inside the protective shell.

[0021] The electronic counter includes a sensor, a magnet, and an electronic counter body. The sensor is vertically mounted on the adsorption frame, and the magnet is mounted on the upper surface of the measuring wheel. The magnet and the sensor work together to detect the number of rotations of the measuring wheel. The sensor is connected to the electronic counter body via a data cable.

[0022] The beneficial effects of this utility model through the above technical solution are:

[0023] The lifting mechanism of this invention has a height adjustment function, which facilitates the simultaneous lifting and lowering of the measuring platform, guide unit, and measuring unit, adapting to steel strands at different heights. The lifting mechanism is manually operated, allowing for flexible control of the lifting height and ensuring that the measuring wheel contacts the steel strand.

[0024] The guiding unit of this invention can accurately guide the steel strand into and out of the metering unit. The two vertical guide rollers in the guiding unit help limit the left and right swaying of the steel strand, and the horizontal guide roller prevents the steel strand from sagging due to gravity.

[0025] The two measuring wheels in the measuring unit of this invention provide a convenient and elastic clamping mechanism for the steel strand, ensuring a tight fit between the measuring wheels and the steel strand. This prevents slippage between the steel strand and the measuring wheels, guaranteeing accurate measurement of the steel strand length. Furthermore, the distance between the two measuring wheels can be adaptively adjusted to flexibly accommodate the specifications of the steel strand. Even if the steel strand experiences slight swaying during operation, the measuring wheels can slide slightly accordingly, effectively adapting to the swaying of the steel strand while maintaining stable rotation of the measuring wheels, thus improving measuring accuracy.

[0026] The adsorption frame of this invention includes a frame body, a soft brush frame, and an adsorption cover, with an exhaust fan connected to the adsorption frame. The soft brush frame contacts the surface of the measuring wheel to clean the zinc powder on the surface of the measuring wheel. The adsorption cover collects and processes the zinc powder in a timely manner, avoiding slippage caused by the presence of zinc powder and ensuring sufficient friction between the steel strand and the measuring wheel.

Detailed Implementation

[0040] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings:

[0041] like Figures 1-12 As shown, the galvanized steel strand double meter counting device includes a lifting mechanism 1, a meter counting platform 4, a guide unit 5, and a meter counting unit 6, as follows: Figures 1-4 As shown. The lifting mechanism 1 is arranged vertically and has a height adjustment function. A metering platform 4 is set above the lifting mechanism 1. The metering platform 4 is arranged horizontally and can be adjusted in height by the lifting mechanism 1.

[0042] In this embodiment, the lifting mechanism 1 is manually operated to achieve height adjustment. The lifting mechanism 1 includes a base plate 101, a telescopic rod 102, and a reinforcing plate 104. Figure 5As shown. The base plate 101 is a rectangular steel plate, which is fixed to the ground with expansion bolts. A telescopic rod 102 is set at the center of the base plate 101. The telescopic rod 102 is vertically arranged and has a telescopic function, which enables the lifting mechanism 1 to be height-adjustable. A triangular reinforcing plate 104 is set between the bottom of the telescopic rod 102 and the base plate 101. Multiple reinforcing plates 104 are evenly distributed in a circumferential direction to ensure the secure installation of the telescopic rod 102.

[0043] The telescopic rod 102 includes a lower cylinder 2, an upper column 3, and a handwheel 103. The lower cylinder 2 is a circular tube structure and is fixedly connected to the base plate 101. A reinforcing plate 104 is arranged between the lower cylinder 2 and the base plate 101 to improve the reliability of the connection between the lower cylinder 2 and the base plate 101. The upper column 3 is inserted inside the lower cylinder 2 and slides up and down inside the lower cylinder 2. The upper column 3 is a screw structure, and its upper end extends out of the lower cylinder 2 and connects to the metering platform 4, thereby supporting the metering platform 4.

[0044] With the lower cylinder 2 fixed and the upper column 3 able to slide up and down, a handwheel 103 is rotatably connected to the upper end of the lower cylinder 2 to enable the upper column 3 to slide. The handwheel 103 is a ring-shaped body with three circumferentially arranged operating levers, which are radially arranged along the handwheel 103. During installation, the upper end of the lower cylinder 2 is provided with an outward flange 201, and the lower end of the handwheel 103 abuts against the outward flange 201, with a plane bearing 10 between them, restricting the downward movement of the handwheel 103. At the same time, multiple vertical bolts 11 are provided circumferentially along the lower edge of the handwheel 103, and the heads of the vertical bolts 11 are locked at the edge of the outward flange 201, restricting the upward movement of the handwheel 103. This prevents the handwheel 103 from moving axially, preventing the handwheel 103 from detaching from the lower cylinder 2, while not interfering with the circumferential rotation of the handwheel 103.

[0045] The installed handwheel 103 is fitted onto the upper column 3 and threadedly connected to it. In order to drive the upper column 3 to move up and down by rotating the handwheel 103, limit bolts 12 are provided on both sides of the lower cylinder 2, and limit grooves 13 are opened on both sides of the upper column 3. The limit bolts 12 and the limit grooves 13 correspond one-to-one. The corresponding limit bolts 12 pass through the lower cylinder 2 and are inserted into the limit grooves 13, thereby preventing the upper column 3 from rotating. Then, by manually operating the handwheel 103 to rotate it, the lifting and lowering of the upper column 3 can be controlled, thereby driving the metering platform 4 to lift and lower.

[0046] The measuring platform 4 is a rectangular plate made of steel. Lifting holes 14 are provided at the four corners of the measuring platform 4. These holes are threaded and used to connect lifting eye bolts, facilitating the lifting and movement of the measuring platform 4. A bottom ring 15 is installed at the center of the lower part of the measuring platform 4. The bottom ring 15 is fitted onto the top of the upper column 3, and a pivot pin passes through it, ensuring a secure installation of the measuring platform 4 to the upper column 3 and preventing the measuring platform 4 from falling off.

[0047] Guide units 5 are set at intervals on both sides of the metering platform 4, and a metering unit 6 is set in the middle of the metering platform 4. The steel strand is threaded between the guide units 5 and the metering unit 6. Under the guidance of the guide units 5, it can be ensured that the running steel strand accurately passes through the metering unit 6. That is, the guide units 5 play a guiding role, which can smoothly guide the steel strand into the metering unit 6 and then lead it to the next process.

[0048] The guide units 5 on both sides are symmetrically arranged. Each guide unit 5 includes a vertical guide roller 51 and a horizontal guide roller 52, as shown below. Figure 6 As shown. There are two vertical guide rollers 51 arranged at intervals. The vertical guide rollers 51 are vertically arranged and located away from the metering unit 6. Each vertical guide roller 51 includes a roller shaft and a roller body. The roller shaft passes through the roller body, and the roller shaft and roller body are rotatably connected. During installation, an elongated hole 16 is provided on the metering platform 4. Vertical guide rollers 51 are arranged on both sides of the elongated hole 16. The roller shaft of each vertical guide roller 51 passes downward through the elongated hole 16 and is connected to a nut. Tightening the nut fixes the vertical guide roller 51, and loosening the nut allows adjustment of the position of the vertical guide roller 51 within the elongated hole 16, thereby adjusting the distance between the two vertical guide rollers 51. The steel strand is wound between the two vertical guide rollers 51, which limit the lateral sway of the steel strand.

[0049] The horizontal guide roller 52 and the vertical guide roller 51 have the same structure. The horizontal guide roller 52 is arranged horizontally and is close to the metering unit 6. The length of the horizontal guide roller 52 is greater than the center distance between the two vertical guide rollers 51. During installation, the metering platform 4 is also equipped with two mounting brackets 17. The mounting brackets 17 are bent into an L-shape, and each mounting bracket 17 has a height adjustment hole 18. The height adjustment hole 18 is a vertically arranged strip hole. The two ends of the roller shaft of the horizontal guide roller 52 extend out of the two height adjustment holes 18 and are connected to nuts. Tightening the nuts can fix the position of the horizontal guide roller 52. After loosening the nuts, the horizontal guide roller 52 can move up and down within the height adjustment hole 18 to adjust its height. The steel strand is wound above the horizontal guide roller 52, so that the horizontal guide roller 52 can restrict the downward movement of the steel strand.

[0050] Meter counting unit 6 can measure the length of steel strand in operation. Meter counting unit 6 includes a slide rail 7, an adsorption frame 8, a meter counting wheel 9, and a counter, such as... Figure 7 and Figure 8 As shown. The slide rail 7 is fixedly connected to the metering platform 4, and the slide rail 7 is arranged perpendicular to the running direction of the steel strand. The two ends of the slide rail 7 are elastically slidably connected to the adsorption frames 8, that is, the adsorption frames 8 slide on the slide rail 7, and the adsorption frames 8 are subjected to elastic force when sliding, so that the two adsorption frames 8 tend to be close together in the initial state.

[0051] During installation, the suction frame 8 has a slider 19 at its bottom. The suction frame 8 is slidably connected to the slide rail 7 via the slider 19, thus the distance between the two suction frames 8 is adjustable. With the cooperation of the slider 19 and the slide rail 7, the suction frame 8 can be raised, maintaining a certain distance between the suction frame 8 and the metering platform 4. A tension spring assembly 21 is also provided between each suction frame 8 and the metering platform 4. The tension spring assembly 21 causes the two suction frames 8 to move closer to each other, and in the initial state, the distance between the two suction frames 8 is minimal.

[0052] In this embodiment, two tension spring assemblies 21 are arranged in parallel on both sides of the slide rail 7. Each tension spring assembly 21 includes a tension spring body 211 arranged in a straight line, a first mounting bolt 212, and a second mounting bolt 213. The first mounting bolt 212 is connected upward to the bottom of the adsorption frame 8, and the second mounting bolt 213 is connected downward to the metering platform 4. There is a gap between the first mounting bolt 212 and the second mounting bolt 213. The two ends of the tension spring body 211 are hooked onto the first mounting bolt 212 and the second mounting bolt 213, respectively. Under the action of the tension spring body 211, the two adsorption frames 8 move relative to each other.

[0053] The adsorption frame 8 has a "U"-shaped cross-section. A measuring wheel 9 is rotatably mounted within each adsorption frame 8. The diameter of the measuring wheel 9 is larger than the width of the adsorption frame 8. The line connecting two measuring wheels 9 is perpendicular to the line connecting two guide units 5, and the line connecting the two guide units 5 is consistent with the running direction of the steel strand. As the two adsorption frames 8 approach each other, the two measuring wheels 9 also approach each other. Under the action of the tension spring assembly 21, an elastic clamping force is generated between the two measuring wheels 9, elastically clamping the steel strand.

[0054] To prevent excessive deviation of the steel strand along the axial direction of the counting wheel 9, limiting sections 91 are arranged at both the upper and lower ends of the counting wheel 9. The diameter of the limiting sections 91 is larger than the diameter of the counting wheel 9. Both the counting wheel 9 and the limiting sections 91 are made of metal. The steel strand contacts the wheel surface of the counting wheel 9 between the two limiting sections 91, and the limiting sections 91 prevent the steel strand from moving up or down out of the counting wheel 9.

[0055] Because the two measuring wheels 9 work together, they can elastically clamp the steel strand. The running steel strand can drive the measuring wheels 9 to rotate, and the length of the steel strand can be determined by monitoring the rotation of the measuring wheels 9. Specifically, each adsorption frame 8 is equipped with a counter, which is connected to the measuring wheels 9 inside the adsorption frame 8 to monitor the number of rotations of the measuring wheels 9. The counter is one or a combination of mechanical counter 20 and electronic counter, that is, it can be monitored by using mechanical counter 20 or electronic counter alone, or by using both mechanical counter 20 and electronic counter simultaneously.

[0056] In this embodiment, the counter is a combination of a mechanical counter 20 and an electronic counter, that is, both the mechanical counter 20 and the electronic counter are used simultaneously to detect the number of rotations of the meter-counting wheel 9. Figure 9 As shown, during installation, a gear set 22 is provided between the input shaft of the mechanical counter 20 and the measuring wheel 9. The gear set 22 consists of two meshing bevel gears. A protective shell 23 is also provided on the adsorption frame 8. The gear set 22 is arranged inside the protective shell 23 to protect the gear set 22.

[0057] The electronic counter includes a sensor 24, a magnet 25, and an electronic counter body. The sensor 24 is vertically mounted on the adsorption frame 8 and is a Hall sensor. The magnet 25 is mounted on the upper surface of the measuring wheel 9, with a certain distance between it and the sensor 24. The magnet 25 and the sensor 24 work together to detect the number of rotations of the measuring wheel 9. The sensor 24 is connected to the electronic counter body via a data cable, which is not shown in the figure.

[0058] The principle of this invention is as follows: Based on the height of the steel strand, the height of the lifting mechanism 1 is adjusted. The lifting mechanism 1 drives the measuring unit 6 to move up and down, causing the steel strand to be placed within the working range of the measuring wheel 9. The measuring wheels 9 are manually moved to both sides to move them away from each other. Then, the steel strand is placed between the two measuring wheels 9. After releasing the measuring wheels 9, under the action of the two tension spring groups 21, the measuring wheels 9 move closer to each other, and the measuring wheels 9 clamp the steel strand.

[0059] During operation, regardless of which direction the steel strand deviates towards the counting wheel 9, the tension spring assembly 21 ensures close contact between the steel strand and the counting wheel 9. This allows the steel strand to reliably drive the counting wheel 9, preventing slippage. Simultaneously, as the counting wheel 9 rotates, the mechanical counter 20 directly monitors the number of rotations, and an electronic counter can also monitor the number of rotations. The length of the steel strand can then be calculated.

[0060] Because the galvanized steel strand rubs against the measuring wheel 9, zinc powder will fall off. To prevent zinc powder from remaining on the surface of the measuring wheel 9, each adsorption frame 8 has an exhaust fan connected to both sides via an air pipe. This allows the fallen zinc powder to be promptly removed. The air pipes and exhaust fans are not shown in the figure. Specifically, the adsorption frame 8 includes a frame body 81, a soft brush frame 82, and an adsorption cover 83. The frame body 81 has a "U"-shaped cross-section and is rotatably connected to the measuring wheel 9. A slider 19 is arranged at the bottom of the frame 81. Figures 10-12 As shown.

[0061] Soft brush frames 82 are arranged around the inside of the frame body 81. There are two soft brush frames 82 arranged on one frame body 81. Specifically, soft brush frames 82 are arranged at both ends of the opening of the frame body 81. The cross-section of the soft brush frame 82 is in the shape of a "hui" character, that is, the soft brush frame 82 is a "hui" character structure formed by connecting and combining four soft brush plates. The soft brush frame 82 is connected to the inner walls around the frame body 81 by screws, and the soft brush frame 82 is in contact with the surface of the counting wheel 9. In this way, each soft brush frame 82 contacts the wheel surface and the upper and lower end surfaces of the counting wheel 9 through the soft brush. During the rotation of the counting wheel 9, the soft brush frame 82 can perform multi-directional zinc powder cleaning on the surface of the counting wheel 9.

[0062] In order to collect and process the removed zinc powder in a timely manner, adsorption covers 83 are respectively arranged on the left and right sides of the frame body 81. The connection line of the two adsorption covers 83 is perpendicular to the connection line of the two soft brush frames 82, and the adsorption covers 83 are arranged between the two soft brush frames 82. One end of the adsorption cover 83 is enlarged and faces the counting wheel 9, and the other end of the adsorption cover 83 is narrowed and is connected to the suction fan through an air pipe.

[0063] Specifically, the adsorption cover 83 includes a rectangular section 26, a conical section 27, a circular pipe section 28 and a filter cartridge 29. The rectangular section 26, the conical section 27 and the circular pipe section 28 are connected in sequence and integrally formed. The size of the rectangular section 26 is larger than the size of the circular pipe section of 28. The rectangular section 26 and the circular pipe section 28 are transitioned through the conical section 27. There is an opening on the frame body 81, and the rectangular section 26 is embedded into the frame body 81 through this opening position. The rectangular section 26 is close to the wheel surface of the counting wheel 9, and the height of the rectangular section 26 is greater than the height of the counting wheel 9.

[0064] An installation ring section 30 is also integrally formed on the conical section 27. The installation ring section 30 is arranged outside the circular pipe section 28, and a filter cartridge 29 is threadedly connected to the installation ring section 30. The filter cartridge 29 includes a cylindrical body 291 with both ends open and a filter element 292 arranged inside the cylindrical body 291. One end of the cylindrical body 291 has a large opening and the other end has a small opening. The large-diameter end of the cylindrical body 291 is threadedly connected to the installation ring section 30, and the circular pipe section 28 is inserted into the cylindrical body 291. The small-diameter end of the cylindrical body 291 is connected to the air pipe.

[0065] The filter element 292 is a hollow cylinder with a cross-section in the shape of a "kan" character. One end of the filter element 292 with an opening faces the circular pipe section 28, and the diameter of the filter cartridge 29 is larger than the diameter of the circular pipe section 28. The filter element 292 is a two-layer structure. The filter element 292 includes a filter cloth layer 2921 and a filter screen layer 2922. The filter screen layer 2922 is used to support the filter cloth layer 2921 to ensure the stability of the shape of the filter cloth layer 2921. The filter screen layer 2922 cooperates with the cylindrical body to clamp the filter cloth layer 292l.

[0066] The entire zinc powder cleaning process is as follows: the soft brush frame 82 sweeps the zinc powder off the surface of the measuring wheel 9. After the exhaust fan is running, the zinc powder within the range of the adsorption hood 83 is extracted through the air pipe. The zinc powder swept by the soft brush frame 82 is then adsorbed into the filter cartridge 29, where it is intercepted and collected by the filter element 292, thus ensuring that there is no zinc powder adhering to the surface of the measuring wheel 9. After the measuring wheel 9 has been running for a period of time, the filter cartridge 29 and the filter element 292 can be removed for zinc powder cleaning. By cleaning the zinc powder, the accumulation of zinc powder on the surface of the measuring wheel 9 is prevented, reducing mechanical friction and ensuring smooth rotation of the measuring wheel 9. At the same time, the presence of zinc powder prevents the steel strand from slipping on the measuring wheel 9 and also prevents zinc powder from interfering with the monitoring operation of the sensor 24 and the magnet 25.
