Description

Technical Field

[0001] The invention relates to the technical field of cord steel sampling, and in particular to a sampling device for cord steel detection. Background Art

[0002] In the modern steel industry, cord steel is mainly used as the basic material of tire skeleton to improve the strength of tires. After the cord steel is produced, a section needs to be cut for mechanical property testing to ensure that it can meet the strict mechanical performance standards.

[0003] Since there are differences in structure and performance of cord steel produced in different batches and under different processes, in order to make the test results comparable, it is necessary to ensure that the sampling length of each section of the sample used for testing is as close as possible, so that the subsequent test data can be compared and measured under the same benchmark to accurately reflect the actual quality status of the cord steel.

[0004] Normally, for the sake of storage convenience and transportation efficiency, the finished cord steel products are generally wound on I-shaped wheels. When the cord steel needs to be tested and sampled, the shape of the finished cord steel is curved because it is in a wound state, which makes it difficult to measure the length accurately. Operators can only measure with the naked eye or simple measuring tools, which results in large errors.

[0005] When manually sampling, workers face irregularly curved cord steel and find it difficult to accurately control the length consistency of each sample cut. This can easily lead to increased discreteness of test data, resulting in deviations in quality assessments, and may also cause multiple wastes of manpower, material resources, and time due to frequent rework and resampling, seriously affecting production efficiency and quality control processes.

[0006] In summary, it is urgent to develop a sampling device that can accurately and efficiently obtain samples of approximately the same length. Summary of the invention

The label paper strip includes a base area and a plurality of identification areas. The pressure mark plate is slidably disposed in the accommodating groove, and the pressure mark plate slides into the limiting groove to attach the marking area to the cord steel material.

[0012] Optionally, there is a dotted tear seam between the identification area and the base area, and the pressure mark plate pushes the identification area after sliding, so as to separate the identification area and the base area along the dotted tear seam.

[0013] Optionally, it further includes a release layer and a second waste collection roller, wherein the release layer is used to carry the label paper strip, and the second waste collection roller is rotatably disposed in the receiving groove, and the second waste collection roller is used to collect the peeled release layer.

[0018] The working principle and beneficial effects of the present invention are: When sampling the cord steel wound on the I-shaped wheel, the operator first passes the end of the finished cord steel through the gap between the wire pressing wheel and the wire support drum, and then continues to guide the cord steel through the wire drawing assembly. At this time, the wire pressing elastic part exerts force on the wire pressing frame with its own elastic potential energy, causing the wire pressing wheel to fit closely to the cord steel, ensuring that it will not be displaced or loosened in subsequent operations.

[0019] Then, the wire pulling assembly clamps the end of the cord steel and slides along the circumferential direction of the wire support drum. Due to the pressing force of the wire pressing wheel, the cord steel is gradually pulled out from the I-shaped wheel during the pulling process and spread along the circumferential surface of the wire support drum.

[0020] When the wire pulling assembly moves to the specified position, the cord steel is tightly supported on the circumference of the support drum, so the operator can accurately determine the length of the current unfolded part of the cord steel according to the circumference of the support drum or the scale line designed on the circumference of the support drum. The operator uses the cutting tool to cut at the appropriate position according to the required sampling length standard to obtain a cord steel sample with a length that meets the test requirements.

[0021] Through the coordinated operation of the wire pulling assembly and the wire support drum, the length of each sampling of the curved cord steel can be accurately determined, which solves the problem of difficulty in judging the length during manual sampling and large length deviations in multiple samplings. It achieves high-precision control of the length of the cord steel samples, provides a unified benchmark for subsequent mechanical properties testing, and improves the accuracy and comparability of test data.

[0022] In addition, because the support drum and the I-shaped wheel are both rotating structures, the support drum can perfectly adapt to the cord steel of different specifications and different bending degrees wound on the I-shaped wheel. During the sampling process, the cord steel is laid on the support drum in a bent state and will not be forcibly changed from its original bending shape, thus avoiding the problem of forcibly straightening the cord steel for the convenience of measuring the sample length, which affects its mechanical properties and the accuracy of subsequent test data.

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0028] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0030] Reference Figure 1 to Figure 12 , which is the first embodiment of the present invention, proposes a sampling device for cord steel detection, including a frame 1, a wire support drum 2, a wire pressing frame 3, a wire pressing wheel 4, a wire pressing elastic member 5 and a wire pulling assembly 6, the wire support drum 2 is arranged on the frame 1, the wire pressing frame 3 is slidably arranged on the frame 1, the wire pressing wheel 4 is rotatably arranged on the wire pressing frame 3, the gap between the wire pressing wheel 4 and the wire support drum 2 is used for the cord steel 7 to pass through, the two ends of the wire pressing elastic member 5 act on the frame 1 and the wire pressing frame 3 respectively, for providing the wire pressing wheel 4 with a force to press the cord steel 7, the wire pulling assembly 6 is slidably arranged along the circumferential direction of the wire support drum 2, and the wire pulling assembly 6 is used to clamp the end of the cord steel 7 and spread it out and tighten it on the circumferential surface of the wire support drum 2.

[0031] In this embodiment, when sampling the cord steel material 7 wound on the I-shaped wheel, the operator first passes the end of the finished cord steel material 7 through the gap between the wire pressing wheel 4 and the wire support drum 2, and then continues to guide the cord steel material 7 through the wire drawing assembly 6. At this time, the wire pressing elastic member 5 exerts a force on the wire pressing frame 3 by virtue of its own elastic potential energy, so that the wire pressing wheel 4 is closely attached to the cord steel material 7, ensuring that it will not be displaced or loosened in subsequent operations.

[0032] Then, the wire drawing assembly 6 clamps the end of the cord steel 7, and the wire drawing assembly 6 slides along the circumferential direction of the wire support drum 2. Due to the pressing force of the wire pressing wheel 4, the cord steel 7 is gradually pulled out from the I-shaped wheel during the pulling process and spread along the circumferential surface of the wire support drum 2.

[0033] When the wire pulling assembly 6 moves to the specified position, since the cord steel material 7 is tightly supported on the circumference of the wire support drum 2, the operator can accurately determine the length of the current unfolded portion of the cord steel material 7 according to the circumferential length of the wire support drum 2 or the scale lines designed on the circumference of the wire support drum 2. The operator uses the cutting tool to perform cutting operations at the appropriate position according to the required sampling length standard to obtain a cord steel sample with a length that meets the detection requirements.

[0034] Through the coordinated operation of the wire pulling assembly 6 and the wire support drum 2, the length of each sampling of the curved cord steel 7 can be conveniently and accurately determined, which solves the problem that it is difficult to judge the length during manual sampling and the length deviation of multiple samplings is large, and achieves high-precision control of the length of the cord steel sample, providing a unified benchmark for subsequent mechanical properties testing and improving the accuracy and comparability of the test data.

[0035] In addition, because the wire support drum 2 and the I-shaped wheel are both rotating body structures, the wire support drum 2 can perfectly adapt to the cord steel 7 of different specifications and different bending degrees wound on the I-shaped wheel. During the sampling process, the cord steel 7 is laid on the wire support drum 2 in a bent state and will not be forcibly changed from its original bending shape, thereby avoiding the problem of forcibly straightening the cord steel 7 for the convenience of measuring the sample length, which affects its mechanical properties and the accuracy of subsequent test data.

[0036] Furthermore, the wire pulling assembly 6 includes a tube body 601, an inner tube 602, a locking bead 603 and a locking spring 604. The tube body 601 is slidably arranged on the circumferential surface of the wire support disk 2. The inner wall of the tube body 601 has a locking cone 6011. The inner tube 602 is slidably arranged in the tube body 601. The side wall of the inner tube 602 is provided with a plurality of accommodating holes 6021 along the circumferential direction. There are a plurality of locking beads 603 and they are movably arranged in the plurality of accommodating holes 6021 respectively. The space between the three locking beads 603 is used to pass the cord steel 7. The two ends of the locking spring 604 act on the tube body 601 and the inner tube 602 respectively, so as to provide a force for the locking bead 603 to approach the locking cone 6011. The locking cone 6011 is used to gather the plurality of locking beads 603 to the middle.

[0037] In this embodiment, when sampling the cord steel material 7, the operator first aligns the end of the cord steel material 7 with the head end of the tube body 601 having the locking cone surface 6011. The cord steel material 7 is inserted into the tube body 601, and the cord steel material 7 first passes through the gap surrounded by the three locking beads 603. In this process, the cord steel material 7 exerts a squeezing force on the locking beads 603, forcing the locking beads 603 to overcome the elastic force of the locking spring 604 and slide into the tube body 601, while sliding outward in the corresponding receiving holes 6021. At this time, since the locking beads 603 are close to the end with a larger diameter of the locking cone surface 6011, the space between the three locking beads 603 becomes larger, so that the cord steel material 7 can pass smoothly until the end of the cord steel material 7 protrudes a certain distance from the tail of the tube body 601. The tube body 601 is installed on a frame that can slide along the circumference of the support drum 2. A pressure wheel is installed on the frame. An elastic member is arranged between the pressure wheel and the frame. The pressure wheel presses the cord steel 7 into the limiting groove 201 through the elastic force of the spring.

[0038] After the cord steel 7 is inserted and reaches the predetermined position, the cord steel 7 is ready to be pulled to move along the circumferential direction of the cable support drum 2. The tube body 601 begins to move. At this time, under the extrusion of the locking cone 6011, the three circumferentially distributed locking beads 603 gather toward the middle, so that the three locking beads 603 are closely attached to the cord steel 7, forming a clamping force to firmly clamp the cord steel 7. Then, as the tube body 601 moves, the cord steel 7 is successfully pulled to slide along the circumferential direction of the cable support drum 2, and the cord steel 7 is gradually pulled out from the I-shaped wheel and spread out and tightened on the circumferential surface of the cable support drum 2. In addition, due to this special structural design, even if the cord steel 7 is subjected to a reverse force, it cannot be pulled out in the original way because the three locking beads 603 are tightly stuck in the locking cone 6011, and can only move from the head of the tube body 601 to the tail.

[0039] The wire pulling assembly 6 does not require additional complicated operations. The cord steel material 7 is automatically clamped after being inserted, which reduces the difficulty of manual operation. The unique one-way movement design prevents the cord steel material 7 from reverse displacement due to external interference or accidental loosening during the sampling process, ensuring the stability of its movement path and stress state every time the cord steel material 7 is pulled. The clamping and fixing process is simplified, and the insertion and fixing of the cord steel material 7 can be completed quickly, which significantly improves the overall work efficiency of sampling the cord steel material 7.

[0040] Furthermore, a limiting groove 201 is provided on the circumferential surface of the wire support drum 2 , and the cross section of the limiting groove 201 is semicircular. The limiting groove 201 is used to accommodate the cord steel material 7 .

[0041] In this embodiment, when sampling, the cord steel 7 can slide into the limiting groove 201. As the wire pulling assembly 6 continues to be pulled, the cord steel 7 follows the trajectory of the limiting groove 201, and fits smoothly and tightly against the semicircular inner wall of the limiting groove 201, providing precise guidance and limitation for the cord steel 7, ensuring that the cord steel 7 will not be deflected or experience unstable conditions on the wire support drum 2.

[0042] Furthermore, it also includes a label roll 8, a waste collection roller 9 and a label pressing plate 10. The support drum 2 has a receiving groove 202, which is connected to the limiting groove 201. The label roll 8 and the waste collection roller 9 are both rotatably arranged in the receiving groove 202. The label roll 8 is formed by winding a label paper strip 801. The label roll 8 and the waste collection roller 9 are used to release and collect the label paper strip 801 respectively. The label paper strip 801 includes a base area 8011 and a plurality of identification areas 8012. The pressure mark plate 10 is slidably disposed in the accommodating groove 202 , and the pressure mark plate 10 slides into the limiting groove 201 to attach the marking area 8012 to the cord steel material 7 .

[0043] In this embodiment, after sampling, a label needs to be attached to the sample to display information such as the batch. The label roll 8 is pre-installed in the receiving slot 202 of the support drum 2 to ensure that the label roll 8 can rotate smoothly. At this time, the label roll 8 wound by the label strip 801 cooperates with the waste collection roller 9 to tighten the label strip 801 so that the label area 8012 is located in front of the label pressing plate 10.

[0044] During labeling, the label pressing plate 10 moves toward the direction close to the cord steel material 7. The label pressing plate 10 first contacts the identification area 8012 of the label paper strip 801. As the label pressing plate 10 continues to move forward, the identification area 8012 is separated from the base area 8011. The label pressing plate 10 slides further and finally abuts against the surface of the cord steel material 7, thereby flatly and firmly sticking the identification area 8012 to the cord steel material 7. Then the label pressing plate 10 quickly resets and waits for the next operation. The staff can write important information such as batch and production date in the identification area 8012.

[0045] A photoelectric sensor can also be configured beside the label pressing plate 10. Whenever the photoelectric sensor detects that the label pressing plate 10 has completely moved back and forth, it means that a labeling operation is completed. At this time, the photoelectric sensor transmits an electrical signal to the drive unit of the label roll 8 and the waste collection roller 9. After receiving the instruction, the drive unit responds quickly, controls the label roll 8 and the waste collection roller 9 to rotate according to the preset program, and accurately moves the next marking area 8012 to the front of the label pressing plate 10 to prepare for the next labeling work. At the same time, the waste collection roller 9 continues to collect those label strips 801 whose marking areas 8012 have been used and only the basic area 8011 is left, ensuring that the working area is always neat and orderly.

[0046] Through this automated labeling mechanism, after sampling is completed, a label containing batch information can be affixed to the cord steel sample, which is convenient for subsequent quality traceability and data analysis. Compared with other marking methods, the labeling method is more eye-catching and neat, with a better reminder effect, which improves the overall work efficiency. The linkage between the photoelectric sensor and the drive unit can continuously provide new identification areas 8012 to ensure the continuity of the labeling work. The setting of the waste collection roller 9 not only holds the label strip 801 tightly, facilitates the pushing of the label pressure plate 10, but also solves the problem of the accumulation of discarded label strips 801.

[0047] Furthermore, there is a dotted tear seam 8013 between the identification area 8012 and the base area 8011. The pressure mark plate 10 pushes the identification area 8012 after sliding, so as to separate the identification area 8012 and the base area 8011 along the dotted tear seam 8013. The pressure mark plate 10 is an arc-shaped plate and matches the cross-sectional shape of the cord steel 7.

[0048] In this embodiment, since the label pressing plate 10 is designed as an arc-shaped plate, its shape can better match the cross-sectional shape of the cord steel material 7, ensuring that the labeling pressure is evenly distributed. A dotted tear seam 8013 is pre-designed between the identification area 8012 and the base area 8011. When the label pressing plate 10 contacts the identification area 8012, only a small thrust is required to smoothly separate the identification area 8012 and the base area 8011 along the dotted tear seam 8013. As the label pressing plate 10 slides further, the separated identification area 8012 is firmly pressed against the cord steel material 7 until the pasting is completed. The design of the dotted tear seam 8013 reduces the difficulty of separating the identification area 8012 from the base area 8011, increases the speed of the labeling process, and reduces the risk of label damage caused by improper separation.

[0049] Furthermore, it also includes a release layer 802 and a second waste collection roller 11, wherein the release layer 802 is used to carry the label strip 801, and the second waste collection roller 11 is rotatably disposed in the receiving groove 202, and the second waste collection roller 11 is used to collect the peeled release layer 802.

[0050] In this embodiment, the release layer 802 carries the label strip 801, which can effectively protect the stickiness of the label strip 801 and keep it in the best standby state. The release layer 802 and the label strip 801 are wound together to form a label roll 8. The starting end of the release layer 802 is peeled off and wound onto the waste collection roller 11. As the labeling work gradually progresses, the waste collection roller 11 starts to rotate under the drive of the corresponding driving device. Due to the rotation of the waste collection roller 11, the release layer 802 is continuously peeled off from the label strip 801, so that the identification area 8012 of the label strip 801 is exposed, creating conditions for the subsequent accurate pushing of the label pressing plate 10. After each pasting of the identification area 8012 is completed, the waste collection roller 11 will collect the newly peeled section of the release layer 802 to ensure that the working area is always clean and tidy, and to prevent the release layer 802 from being scattered randomly and interfering with the labeling process.

[0051] The stickiness of the release layer 802 and the label strip 801 provides a protective barrier, ensuring that the label strip 801 always maintains good stickiness during long-term storage and under different environmental conditions. The coordinated operation of the waste collection roller 11 and the release layer 802 realizes the orderly peeling of the label strip 801 and ensures a continuous supply of labels. The waste collection roller 11 collects the peeled release layer 802 in a timely manner, effectively preventing the release layer 802 from accumulating and winding in the working area.

[0052] Furthermore, it also includes a linkage rod 12 and a linkage spring 13, the linkage rod 12 is arranged on the pressure mark plate 10, the end of the linkage rod 12 has a guide slope 1201, the two ends of the linkage spring 13 act on the support disk 2 and the linkage rod 12 respectively, for providing a force for the pressure mark plate 10 to move away from the marking area 8012, and the tube body 601 slides close to the guide slope 1201 and then contacts the guide slope 1201, for providing a force for the pressure mark plate 10 to move close to the marking area 8012.

[0053] In this embodiment, when sampling, the tube body 601 in the wire pulling assembly 6 slides along the circumferential direction of the wire support disk 2. When the tube body 601 slides to the position where the linkage rod 12 is located, the end of the tube body 601 contacts the guiding inclined surface 1201 at the end of the linkage rod 12. As the tube body 601 continues to move, under the guidance of the guiding inclined surface 1201, the tube body 601 applies a lateral thrust to the linkage rod 12. At this time, the linkage rod 12 overcomes the elastic resistance of the linkage spring 13, and drives the label pressing plate 10 connected thereto to slide toward the marking area 8012, thereby completing the subsequent labeling action.

[0054] By designing the linkage rod 12 and the linkage spring 13, the tube body 601 can automatically perform labeling after sliding to the specified position, and the sliding action of the tube body 601 is cleverly linked with the labeling action of the label pressing plate 10, so as to realize the automatic linkage between the two. The design of the guide slope 1201 makes the sliding timing of the label pressing plate 10 match the movement of the tube body 601, thus avoiding labeling errors caused by uncoordinated actions, such as the offset of the pasting position of the label area 8012.

[0055] Furthermore, it also includes a mounting frame 14, a clamping plate 15 and a limiting portion 16. The mounting frame 14 is slidably arranged on the circumferential surface of the wire support drum 2. The middle part of the clamping plate 15 is hinged to the mounting frame 14. The clamping plate 15 is symmetrically arranged with two parts. The clamping plate 15 has a first end 1501 and a second end 1502. The limiting parts 16 are arranged in pairs on the mounting frame 14 to block the second end 1502 of the clamping plate 15. The clamping plate 15 has a closed state and an open state. In the open state, the first ends 1501 of the two clamps 15 are opened to both sides, and the second ends 1502 of the clamps 15 abut against one of the limiting portions 16; In the closed state, the first ends 1501 of the two clamping plates 15 jointly clamp the portion of the cord steel 7 protruding out of the wire pulling assembly 6 , and the second end 1502 of the clamping plate 15 abuts against the other limiting portion 16 .

[0056] In this embodiment, in the initial state, the clamping plates 15 are in an open state, that is, the first ends 1501 of the two clamping plates 15 are opened to both sides, and the second ends 1502 of the clamping plates 15 abut against one of the limiting portions 16, ready to receive the cord steel 7. When the tube body 601 slides along the circumferential surface of the support drum 2 to the position of the mounting frame 14, the protruding portion of the cord steel 7 enters the gap between the first ends 1501 of the two clamping plates 15, and then the clamping plates 15 rotate around the central hinge point, and the second ends 1502 are separated from the originally abutted limiting portion 16 and abut against another limiting portion 16, and the first ends 1501 of the two clamping plates 15 jointly clamp the portion of the cord steel 7 protruding out of the tube body 601. Subsequently, the tube body 601 starts to slide in the reverse direction. Since the end of the cord steel 7 has been clamped by the clamping plates 15, as the tube body 601 moves in the reverse direction, the cord steel 7 is gradually pulled out of the tube body 601, and the operator can easily remove it.

[0057] Furthermore, a clamping spring 17 is included, and two ends of the clamping spring 17 act on the first end 1501 of the clamping plate 15 and the mounting frame 14 respectively, so as to provide a force for the second end 1502 of the clamping plate 15 to press against one of the limiting parts 16. The tube body 601 has a push portion 18 . After the tube body 601 slides, the push portion 18 pushes the second end 1502 of the clamping plate 15 to swing the clamping plate 15 to a closed state.

[0058] In this embodiment, in the initial state, the clamping plate 15 is in an open state, and its second end 1502 is firmly pressed against one of the limit parts 16 under the tension of the clamping spring 17. When the tube body 601 slides to the position of the mounting frame 14, the push part 18 starts to push the second end 1502 of the clamping plate 15. The end of the push part 18 is designed to be conical, which can smoothly contact and push the second end 1502 of the clamping plate 15, thereby overcoming the tension of the clamping spring 17, and the clamping plate 15 starts to swing around the middle hinge point. In this process, the clamping spring 17 is gradually stretched, accumulating elastic potential energy, and the second end 1502 of the clamping plate 15 is separated from the originally pressed limit part 16. When the clamping plate 15 swings to the other side, under the tensile force of the clamping spring 17 rebounding, the second end 1502 of the clamping plate 15 quickly presses against another limit part 16, so that the clamping plate 15 swings to a closed state, thereby clamping the part of the cord steel 7 protruding out of the tube body 601. Subsequently, the tube body 601 slides in the reverse direction. Since the clamping plate 15 has clamped the end of the cord steel 7, the cord steel 7 is pulled out of the tube body 601 under the traction of the reverse movement of the tube body 601. Finally, the operator can easily remove the sample and complete the entire sampling process.

[0059] The designed push portion 18 of the tube body 601 and the clamping spring 17 realize the linkage between the movement of the tube body 601 and the clamping action of the clamping plate 15. There is no need to manually switch the state of the clamping plate 15, which significantly improves the production inspection efficiency.

[0060] Furthermore, it also includes a cutting knife 19 , which is slidably arranged on the frame 1 and is used for cutting the cord steel material 7 . There are two crimping wheels 4 , and the cutting knife 19 is located between the two crimping wheels 4 .

[0061] In this embodiment, when the cord steel material 7 is spread and tightened along the circumference of the cable support drum 2 by the cable pulling assembly 6, the operator starts the cutting process after accurately judging that the required sampling length has been reached based on the circumference length of the cable support drum 2 or the scale lines set thereon. At this time, the cutting knife 19 installed on the frame 1 starts to slide rapidly and smoothly along the predetermined track under the push of the driving device (such as a cylinder, an electric push rod, etc., depending on the actual design).

[0062] Since the cutting knife 19 is located between the two pressing wheels 4, when the cutting knife 19 gradually approaches the cord steel 7, the two pressing wheels 4 firmly press the cord steel 7 so that it will not be displaced at the moment of being cut, ensuring the accuracy of the cutting position.

[0063] After the cutting is completed, the two pressing wheels 4 still press the remaining cord steel 7. The rebound of the cord steel 7 is effectively avoided, and the safety is improved.
