Description

Technical Field

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

[0002] Steel cord is a special-purpose fine steel strand or rope made of high-quality high-carbon steel with brass coating on the surface. It is mainly used for car tires, light truck tires, heavy truck tires, construction machinery tires, aircraft tires and other rubber product skeleton materials. The radial tire made of steel cord as reinforcement material has the advantages of long service life, high driving speed, puncture resistance, good elasticity, safety and comfort, and fuel saving.

[0003] In the production process of steel cord, the processed steel cord needs to be twisted into strands on a winding roller. At present, when the steel cord has appearance defects in the twisting process, it can only be judged by surface recognition devices or manually with the naked eye. The former requires high purchase and use costs, while the latter has a low detection rate for appearance defects.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. By setting up structures such as conveying rollers, winding rollers and circular ring blocks, turning on the motor, the motor output end drives multiple circular ring blocks to rotate through the rotating shaft, wide gear and annular rack, so that multiple ball detection blocks slide along the circumference of the steel cord, so that the ball detection blocks arranged inside the multiple circular ring blocks are within the detection range of the spiral track on the side wall of the steel cord, and then the detection range of the spiral track will cover the circumference of the steel cord;

[0019] 2.

[0020] 3. Under the action of the movable end of the electric push rod, the annular force sensor is made to slide back and forth in the vertical direction synchronously with the test platform. Then the annular force sensor will be pressed against the steel cord to obtain the size of the extrusion force between the annular force sensor and the steel cord, and then the stretching state of the steel cord between the conveying roller and the winding roller is judged, thereby judging the twisting quality of the steel cord on the winding roller;

[0021] 4. The eccentric shaft will drive the sliding plug to slide back and forth in a sealed manner inside the box body through the first push rod, and then the box body will draw the external lubricating oil into the box body, and then squeeze it to multiple oil spray heads for spraying. Under the action of the bristles, the lubricating oil can be better smeared and covered with the side wall of the steel cord, thereby improving the lubrication and protection effect of the steel cord.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Fig. 9 A steel cord surface detection device comprises a base 1, a winding roller 2, a conveying roller 3 and a plurality of circular blocks 5 for steel cord detection, a support plate 101 is installed on the top of the base 1, and an annular cavity 6 (such as Figure 3 As shown), a plurality of detection mechanisms are evenly distributed inside the annular cavity 6;

[0034] Each detection mechanism includes a detection rod 7 that passes through and is slidably connected to the inner wall of the annular cavity 6, a circular shaft 8 is fixedly connected to the side wall of one end of the detection rod 7, a first gear 9 is rotatably connected to the side wall of the circular shaft 8, a first rack 10 is fixedly connected to the inner wall of the annular cavity 6, a second rack 12 is slidably connected to the inner wall of the annular cavity 6, a round pin 13 is fixedly connected to the side wall of the second rack 12, a second gear 14 is rotatably connected to the side wall of the round pin 13, a third rack 15 is fixedly connected to the inner wall of the annular cavity 6, a detection box 17 is fixedly connected to the inner wall of the annular cavity 6, a fourth rack 16 is slidably connected to the inner wall of the detection box 17, a conductive block 18 is fixedly connected to one end of the fourth rack 16, an annular conductive plate 19 is symmetrically fixedly connected to the inner wall of the detection box 17, an alarm 32 is fixedly connected to the side wall of the annular block 5, and each annular conductive plate 19 is electrically connected to the conductive block 18 and the alarm 32.

[0035] The end of the detection rod 7 away from the first gear 9 is fixedly connected with a ball detection block 21. The ball detection block 21 is a truncated cone-shaped block, and a freely rolling ball is embedded in the narrow end thereof, so that the ball portion of the ball detection block 21 can always roll against the side wall of the steel cord. The first gear 9 is meshed with the first rack 10, the first gear 9 is meshed with the second rack 12, the second gear 14 is meshed with the third rack 15, the second gear 14 is meshed with the fourth rack 16, and the side wall of the fourth rack 16 is sleeved with a return spring 20, and one end of the return spring 20 is fixed to the side wall of the fourth rack 16.

After the magnetic spring 46 is energized, due to electromagnetic induction, the magnetic spring 46 interacts with the current in the external magnetic field to generate different sizes of pulling force to control the tensile deformation and movement state of the magnetic spring 46. That is, after the magnetic spring 46 is energized, the magnetic spring 46 will contract, thereby driving the detection rod 7 to slide a short distance, so that no interference will be generated in the process of the steel cord passing through the circular ring block 5.

[0036] The inner wall of the support plate 101 is fixedly connected to an electric slide rail 4, and the bottom wall of the electric slide rail 4 is slidably matched with an electric slider 401. The electric slider 401 and the electric slide rail 4 are both existing technologies and are not described in detail here. The bottom wall of the electric slider 401 is fixedly connected to a connecting block 45, and a semicircular through hole 11 is provided on the bottom wall of the connecting block 45. A plurality of arc grooves 27 are provided on the inner wall of the semicircular through hole 11. The side wall of each circular ring block 5 is slidably connected to the inner wall of a corresponding arc groove 27, and each circular ring block 5 slides on the inner wall of the arc groove 27 to produce a rotation effect.

[0037] The side wall of each annular block 5 is fixedly connected with an annular rack 29, the side wall of the electric slider 401 is fixedly connected with a motor 22 through a bracket, the output end of the motor 22 is fixedly connected with a rotating shaft 24, the side wall of the rotating shaft 24 is fixedly connected with a wide gear 23, and the annular rack 29 and the wide gear 23 are meshingly connected.

[0038] The side wall of the support plate 101 is slidably connected to a detection platform 30 along the vertical direction, an electric push rod 28 is installed on the top of the base 1, the movable end of the electric push rod 28 is fixedly connected to the detection platform 30, and an annular force sensor 31 is slidably connected to the detection platform 30. The annular force sensor 31 is a prior art and can detect and read the extrusion force value of contact extrusion.

[0039] The side wall of the electric slider 401 is fixedly connected to the box body 35 through a support rod, the inner wall of the box body 35 is sealingly and slidably connected to the sliding plug 34, the end of the rotating shaft 24 away from the motor 22 is fixedly connected to the circular plate 25, the side wall of the circular plate 25 is eccentrically fixedly connected to the eccentric shaft 26, the side wall of the eccentric shaft 26 is rotatably connected to the first push rod 33, and the end of the first push rod 33 away from the eccentric shaft 26 is rotatably connected to the side wall of the sliding plug 34.

[0040] A plurality of slide grooves 38 are evenly distributed on the inner wall of the annular block 5, and a tension spring 39 is fixedly connected to the inner wall of each slide groove 38, and a slide column 40 is fixedly connected to the other end of the tension spring 39, and an arc plate 41 is fixedly connected to the end of the slide column 40 away from the tension spring 39, and a plurality of bristles 43 are fixedly connected to the bottom wall of each arc plate 41, and a plurality of oil spray heads 42 are embedded and fixed on the inner wall of the semicircular through hole 11.

[0041] A one-way oil inlet pipe 36 and a plurality of one-way oil outlet pipes 37 are fixedly connected through the inner wall of the box body 35. The other end of the one-way oil outlet pipe 37 is fixedly connected to an oil spray head 42. The end of the one-way oil inlet pipe 36 away from the box body 35 is fixedly connected to an external lubricating oil tank. The one-way oil inlet pipe 36 only allows external lubricating oil to enter the box body 35, and the one-way oil outlet pipe 37 only allows the lubricating oil inside the box body 35 to be squeezed into the oil spray head 42 for spraying.

[0042] The conveying roller 3 is fixedly mounted on the top of the base 1 , and the winding roller 2 is fixedly mounted on the top wall of the base 1 .

[0043] In the present invention, the steel cord to be twisted passes through multiple circular blocks 5, the conveying roller 3, the annular force sensor 31 and the winding roller 2 in sequence, and is finally twisted into strands on the winding roller 2. The steel cord is in a stretched state between the conveying roller 3 and the winding roller 2, and the electric slider 401 slides back and forth on the electric slide rail 4, and then drives the multiple circular blocks 5 to move along the axial direction of the winding roller 2 through the connecting block 45, cooperating with the twisting operation of the steel cord.

[0044] When the steel cord passes through multiple circular blocks 5, the detection rod 7 that is slidably connected through the side wall of each circular block 5 will contact the side wall of the steel cord through the ball detection block 21, and relative sliding will occur when the steel cord is transported. The motor 22 is turned on, and the output end of the motor 22 drives the rotating shaft 24 to rotate. The rotating shaft 24 drives the multiple circular blocks 5 to rotate through the wide gear 23 and multiple annular racks 29, so that the multiple ball detection blocks 21 slide along the circumference of the steel cord, and under the action of the magnetic spring 46, each ball detection block 21 is in contact with the side wall of the steel cord. In the process of twisting the steel cord, the ball detection blocks 21 arranged inside the multiple circular blocks 5 are in the detection range of the spiral trajectory of the side wall of the steel cord. When the twisting speed of the steel cord is slow, the detection range of the spiral trajectory will cover the circumference of the steel cord.

[0045] When the side wall of the steel cord has a poor quality defect (such as steel chip protrusion), at this time, after one of the ball detection blocks 21 and the poor quality defect (such as steel chip protrusion) are offset, the ball detection block 21 will drive the detection rod 7 to slide a distance, then the detection rod 7 will drive the first gear 9 to move synchronously, since the first gear 9 is meshingly connected with the first rack 10, and the first rack 10 is fixedly connected to the inner wall of the annular cavity 6, then the first gear 9 will rotate, thereby driving the second rack 12 to slide, since the bottom wall of the second rack 12 is rotationally connected to the second gear 14, and the second gear 14 is meshingly connected with the third rack 15, then the second gear 14 will rotate and drive the fourth rack 16 to move a distance, and after the fourth rack 16 slides for a distance, it will drive the conductive block 18 and one of the annular conductive plates 19 to contact each other, thereby forming a path between the annular conductive plate 19, the conductive block 18 and the alarm 32, then the alarm 32 will be energized to produce a buzzing sound, prompting the user that this part of the steel cord being twisted has a poor quality characteristic. When the side wall of the steel cord has a poor quality defect (such as a depression), the ball detection block 21 will drive the detection rod 7 to move a certain distance deeper into the depressed part of the steel cord under the elastic force of the magnetic spring 46. Then the ball detection block 21 will drive the first gear 9 to move in the opposite direction through the detection rod 7, thereby causing the conductive block 18 and another annular conductive plate 19 to come into contact with each other, so that a passage is formed between the annular conductive plate 19, the conductive block 18 and the alarm 32. Then the alarm 32 will be energized to produce a buzzing sound, indicating that a quality defect has occurred on the side of the steel cord.

[0046] Due to the provision of the first rack 10, the second rack 12, the third rack 15 and the fourth rack 16 and the first gear 9 and the second gear 14 and other structures, when the side wall of the steel cord has poor quality defects, the movement stroke of the ball detection block 21 can be amplified several times. Then, even if the poor quality defects of the side wall of the steel cord are small, the ball detection block 21 can still detect it by amplifying the stroke, thereby improving the detection ability of poor quality defects in the twisting process of the steel cord.

[0047] The user turns on the electric push rod 28, and the movable end of the electric push rod 28 drives the detection platform 30 to slide back and forth in the vertical direction. Since the detection platform 30 is slidably connected with the annular force sensor 31, and the steel cord passes through the annular force sensor 31, the annular force sensor 31 will slide back and forth in the vertical direction synchronously with the detection platform 30, and the annular force sensor 31 will be pressed against the steel cord to obtain the extrusion force between the annular force sensor 31 and the steel cord, and then the stretching state of the steel cord between the conveying roller 3 and the winding roller 2 is judged, thereby judging the twisting quality of the steel cord on the winding roller 2.

[0048] The output end of the motor 22 will drive the circular plate 25 to rotate through the rotating shaft 24, and then the circular plate 25 will drive the eccentric shaft 26 eccentrically set on its side wall to rotate synchronously, and the eccentric shaft 26 will drive the sliding plug 34 to slide back and forth in a sealed manner inside the box body 35 through the first push rod 33, and then the box body 35 will draw the external lubricating oil into the box body 35 through the one-way oil inlet pipe 36, and then squeeze it to multiple oil spray heads 42 through the one-way oil outlet pipe 37 for spraying. The lubricating oil sprayed from the oil spray head 42 adheres to the steel cord, and the bristles 43 are in contact with the side wall of the steel cord. Then, under the action of the bristles 43, the lubricating oil can be better smeared and covered with the side wall of the steel cord, thereby improving the lubrication and protection effect of the steel cord.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
