Description

Technical Field

[0001] This utility model relates to the field of steel cord production technology, and more specifically to a meter counter for steel cord unwinding. Background Technology

[0002] The length in meters is one of the most critical indicators for rope making equipment. Errors in the length in meters usually cause quality problems due to inconsistent lengths used by customers. The confirmation of the length in meters for rope making equipment usually requires multiple verifications. Not only does the accuracy of the metering system on the machine need to be regularly maintained and confirmed, but other equipment or devices are also used to conduct repeated confirmation and calibration processes.

[0003] Our company's original calibration length usually involves transferring the product to another reflowing device for reconfirmation and error calibration after the equipment has run for one standard length. This operation is cumbersome, time-consuming, and there is also a risk of damaging the product during the transfer. It is evident that in the continuous wire feeding production process of steel cord, ensuring that the length meets customer requirements requires more time and process complexity, while reducing production costs carries the risk of non-compliant length.

[0004] Therefore, it is crucial to balance the cost of modification with the requirement of meter length error, that is, to propose a low-cost, high-precision meter counter. Summary of the Invention

[0005] To address the technical problems existing in the current steel cord laying meter counting technology, this utility model proposes a steel cord laying meter counting device, including a tension wheel set, a meter counting wheel set, and a meter length monitoring component; The tension wheel assembly includes a tension wheel and a pressure sensor that monitors the pressure on the tension wheel axle. The meter counting wheel set includes a main meter counting wheel and an auxiliary meter counting wheel. The steel wire released by the wire feeding device passes sequentially around the car platform meter counter, the tension wheel set, the main meter counting wheel and the auxiliary meter counting wheel, and is wound around the surface of the main meter counting wheel at least three times. The meter length monitoring component is used to monitor the number of rotations of the main meter wheel.

[0006] Preferably, the main meter wheel is configured to include at least three grooves, and at least two of the grooves are deformable grooves. The deformable grooves are configured to include a first state and a second state. In the first state, the outer contour of the groove is circular, and in the second state, the outer contour of the groove is a continuous curve structure with periodically changing curvature.

[0007] Preferably, when the pressure detected by the pressure sensor exceeds the threshold, the deformable wheel groove switches from the first state to the second state.

[0008] Preferably, the outer contour of the deformable wheel groove in the second state is set to be elliptical.

[0009] Preferably, the major axis of the ellipse of the first deformable wheel groove is perpendicular to the major axis of the ellipse of the second deformable wheel groove.

[0010] Preferably, the deformable wheel groove includes a first wheel body and a second wheel body, which are arranged in parallel. The first wheel body has a first contour surface, and the second wheel body has a second contour surface. The meter-counting wheel set also includes a wire-shifting component, which is used to control the steel wire to be wound around the first or second contour surface of the deformable wheel groove, so that the deformable wheel groove switches to a first state or a second state.

[0011] Preferably, the main measuring wheel includes a fixed wheel groove and a first deformable wheel groove and a second deformable wheel groove located on both sides of the fixed wheel groove. The fixed wheel groove is provided with a first groove body, the first deformable wheel groove is provided with a second groove body, and the second deformable wheel groove is provided with a third groove body. Both the second groove body and the third groove body are deformable wheel grooves.

[0012] Preferably, the auxiliary meter counting wheel has one more groove than the main meter counting wheel. The steel wire is first wound into the groove of the auxiliary meter counting wheel, and then alternately wound on the groove surfaces of the main meter counting wheel and the auxiliary meter counting wheel before being wound out of the groove of the auxiliary meter counting wheel.

[0013] Preferably, the diameter of the auxiliary meter wheel is smaller than the diameter of the main meter wheel.

[0014] Compared with the prior art, the advantages of this utility model are: This invention utilizes the elliptical contour switching method of the deformable wheel groove to create a local high-pressure anchoring effect in the short axis area during tension fluctuations. This increases the friction coefficient between the steel wire and the wheel groove, effectively suppressing slippage and maintaining stable meter counting even under tension fluctuations. This improves the accuracy of the meter counting wheel and avoids the traditional rewinding and re-inspection process. In addition, the deformable wheel groove adopts a modular design, and the carbon fiber polyurethane wheel surface can be replaced individually, which reduces maintenance costs compared to replacing the entire wheel.

Detailed Implementation

[0016] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0017] Combination Figure 1 As shown, this utility model proposes a meter counter for steel cord unwinding, including a tension wheel assembly 100, a meter counting wheel assembly 200, and a meter length monitoring component 300. The tension wheel assembly 100 is located upstream of the meter counting wheel assembly 200 and is mainly used to filter tension fluctuations during upstream unwinding. The meter counting wheel assembly 200 is used to convert the unwinding length in meters into the number of rotations, and the meter length monitoring component 300 is used to monitor this data and provide feedback on the actual unwinding length in meters.

[0018] The tension wheel assembly 100 includes a tension wheel 110 and a pressure sensor that monitors the pressure on the axle of the tension wheel 110.

[0019] Combination Figure 2 As shown, in addition to the tension wheel 110, the tension wheel assembly 100 also includes a mounting plate that supports the tension wheel 110. The mounting plate is provided with two wire guide wheels. The tension wheel 110 is elastically connected to the mounting plate, so that when the wire unwinding tension changes, the tension wheel 110 can generate elastic displacement, and this tension change can be detected by a pressure sensor.

[0020] Furthermore, the mounting plate is also provided with a support rod 120, and an end guide wheel 130 is provided at the end of the support rod 120. The meter counting wheel set 200 is installed on the support rod 120.

[0021] Optionally, the meter counting wheel set 200 includes a main meter counting wheel 210 and an auxiliary meter counting wheel 220. The steel wire released by the wire feeding device passes sequentially around the machine meter counter, tension wheel set 100, main meter counting wheel 210 and auxiliary meter counting wheel 220, and is wound around the surface of the main meter counting wheel 210 at least three times.

[0022] It should be understood that the measuring wheel set 200 is required to accurately reflect the length of the wire laid out in meters. Therefore, the wire should slip as little as possible on the surface of the main measuring wheel 210. Thus, slippage can be avoided by increasing the number of turns wound on the surface of the main measuring wheel 210.

[0023] Furthermore, the meter length monitoring component 300 is used to monitor the number of rotations of the main meter wheel 210, and the actual wire length data can be detected based on the number of rotations of the main meter wheel 210.

[0024] Combination Figure 3 As shown, the main meter wheel 210 is configured to include at least three grooves, and at least two of the grooves are deformable grooves. The deformable grooves are configured to include a first state and a second state. In the first state, the outer contour of the groove is circular, and in the second state, the outer contour of the groove is a continuous curve structure with periodically changing curvature.

[0025] Thus, the steel wire that passes around the main measuring wheel 210 must pass around three wheel grooves respectively. Slippage is most likely to occur when tension fluctuates. Therefore, in response to tension changes, slippage caused by tension changes can be reduced by changing the surface profile of the wheel groove. In particular, after the outer profile of the wheel groove is constructed as a non-circular curved profile, the mechanical engagement effect between the steel wire and the wheel surface can be dynamically enhanced, thus suppressing slippage.

[0026] Combination Figure 2 As shown, the auxiliary measuring wheel 220 has one more groove than the main measuring wheel 210. The steel wire first enters through the groove of the auxiliary measuring wheel 220, then alternately winds around the groove surfaces of the main measuring wheel 210 and the auxiliary measuring wheel 220, and finally exits through the groove of the auxiliary measuring wheel 220. The diameter of the auxiliary measuring wheel 220 is smaller than the diameter of the main measuring wheel 210.

[0027] Thus, the steel wire has a large wrap angle on the surface of the main measuring wheel 210, which can form a larger contact area.

[0028] Furthermore, the deformable wheel groove is configured to include a first state and a second state that can be switched according to tension changes. That is, when the pressure detected by the pressure sensor exceeds the threshold, the deformable wheel groove switches from the first state to the second state.

[0029] In an optional embodiment, the outer contour of the deformable wheel groove in the second state is set to be elliptical, and the major axis of the ellipse of the first deformable wheel groove is perpendicular to the major axis of the ellipse of the second deformable wheel groove.

[0030] Thus, by constructing an orthogonal ellipse, the steel wire passes sequentially through the major axis of the ellipse, the circular profile, and the minor axis of the ellipse during winding. This causes uneven changes in stress and pressure during the winding process, which increases the effective coefficient of friction and suppresses slippage.

[0031] Combination Figure 1 As shown in Figure 4, the main meter wheel 210 includes a fixed wheel groove 211 and a first deformable wheel groove 212 and a second deformable wheel groove 213 located on both sides of the fixed wheel groove 211. The fixed wheel groove 211 is provided with a first groove body 202, the first deformable wheel groove 212 is provided with a second groove body 203, and the second deformable wheel groove 213 is provided with a third groove body 201. Both the second groove body 203 and the third groove body 201 are deformable wheel grooves.

[0032] The steel wire passes through the second groove 203, the first groove 202 and the third groove 201 in sequence. Since the second groove 203 and the third groove 203 are both deformable grooves, when the wire tension changes, the pressure of the steel wire in the second groove 203 or the third groove 201 increases, which suppresses slippage.

[0033] The deformable wheel groove includes a first wheel body and a second wheel body, which are arranged in parallel. The first wheel body has a first contour surface and the second wheel body has a second contour surface. The meter wheel set also includes a wire-shifting component 230, which is used to control the steel wire to be wound on the first or second contour surface of the deformable wheel groove, so that the deformable wheel groove can be switched to the first or second state.

[0034] Specifically, in combination Figure 3 as well as Figure 5 As shown, the second groove 203 is provided with a first circular contour surface 203a and a first elliptical contour surface 203b, and the third groove 201 is provided with a second circular contour surface 201a and a second elliptical contour surface 201b. The wire-pulling component 230 includes a first wire-pulling clamp 231 and a second wire-pulling clamp 232. The first wire-pulling clamp 231 and the second wire-pulling clamp 232 are controlled synchronously to switch the steel wire from the position of the first circular contour surface 201a and the second circular contour surface 203a to the position of the first elliptical contour surface 201b and the second elliptical contour surface 203b, or to the opposite direction. The movement of the first wire-pulling clamp 231 and the second wire-pulling clamp 232 can be controlled by an electromagnetic drive structure.

[0035] Combination Figure 4a and Figure 4b As shown, by displacing the first wire clamp 231 and the second wire clamp 232, the steel wire can flexibly switch between the circular and elliptical contour surfaces, realizing the switching between the first and second states of the deformable wheel groove. Therefore, by controlling the steel wire to be in different positions according to the tension change of the wire feeding, slippage caused by tension change can be effectively suppressed.

[0036] In an optional embodiment, the first deformable wheel groove 212 and the second deformable wheel groove 213 are detachably connected to both sides of the fixed wheel groove 211. The fixed wheel groove 211 is made entirely of stainless steel, while the first deformable wheel groove 212 and the second deformable wheel groove 213 are made of stainless steel and carbon fiber reinforced polyurethane.

[0037] The fixed wheel groove 211 has connecting structures 211a on both sides and a wheel surface 211b in the middle. A first groove 202 is formed between the connecting structures 211a and the wheel surface 211b. The spokes of the fixed wheel groove 211 are also provided with positioning holes 211c, which are used to position the rotational speed of the main meter wheel 210.

[0038] Among them, the wheel frame 212a and the extension structure 212b of the first deformable wheel groove 212 are made of stainless steel, and the first circular contour surface 203a and the first elliptical contour surface 203b fitted on the surface of the extension structure 212b are made of carbon fiber reinforced polyurethane (e.g., Figure 7 (As shown).

[0039] Among them, the wheel frame 213a and the extension structure 213b of the second deformable wheel groove 213 are made of stainless steel, and the second circular contour surface 201a and the second elliptical contour surface 201b fitted on the surface of the extension structure 212b are made of carbon fiber reinforced polyurethane (e.g., Figure 6 (As shown).

[0040] Optionally, the inner side of the connecting structure 211a has a plug-in structure, into which the extension structure can be inserted and fixed by a pin connection.

[0041] Thus, compared to stainless steel wheel surfaces, the first circular profile surface 203a, the first elliptical profile surface 203b, the second circular profile surface 201a, and the second elliptical profile surface 201b made of carbon fiber reinforced polyurethane material have greater contact friction. To ensure accuracy, they can be replaced after the predetermined length of the line has been laid out.

[0042] In the above embodiment, the controller 310 is configured to control the wire feeding device to stop feeding when the error rate Q > 0.5%, and to issue a warning message when the error rate Q increases continuously for three consecutive feeding cycles.

[0043] In this way, by deploying two meter counters online, the meter length monitoring component 300 is used to monitor the number of rotations of the main meter counter wheel 210 to generate meter length data, which is then compared and calibrated with the vehicle-mounted meter counter. This provides feedback on the operating status of the vehicle-mounted meter counter, and the two counters form a mutual reflection relationship. This reduces the need for repeated meter length verification steps and prevents products with meter length errors from reaching the customer.

[0044] Preferably, the meter counting wheel set 200 is replaced according to the specified meter length cycle.

[0045] Optionally, replacement conditions include a cumulative length of 500 kilometers, a wear depth of >0.1 mm on the carbon fiber polyurethane profile surface, or more than 10,000 elliptical profile switching times.

[0046] In conjunction with the above embodiments, this utility model, through the elliptical contour switching method of the deformable wheel groove, forms a local high-pressure anchoring effect in the short axis area when the tension fluctuates, thereby increasing the friction coefficient between the steel wire and the wheel groove, effectively suppressing slippage, maintaining stable meter counting even under tension fluctuations, improving the accuracy of the meter counting wheel, and avoiding the traditional rewinding and re-inspection process. In addition, the deformable wheel groove adopts a modular design, and the carbon fiber polyurethane wheel surface can be replaced individually, which reduces maintenance costs compared to replacing the whole wheel.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
