Description

Technical Field

[0001] This utility model relates to the field of cold rolling equipment technology, and in particular to a sampling device for the certification of cold rolled strip steel. Background Technology

[0002] Cold-rolled strip steel refers to strip steel and sheet steel produced by cold rolling at room temperature using hot-rolled strip steel and steel plate as raw materials.

[0003] In the prior art, invention patent with patent number 201910644843.8 discloses a sampling method and sampling line for hot-rolled strip steel, and invention patent with patent number 202110501946.6 discloses an online sampling device for hot-rolled strip steel. The sampling methods in the above-mentioned prior art all require the strip steel to be moved to the device for sampling after the rewinding unit is opened in advance. The whole sampling process is cumbersome, easy to cause damage, which is not conducive to the sampling results. Moreover, the whole device occupies a lot of space, which is not conducive to strip steel production.

[0004] During the sampling process of cold-rolled strip steel, the cold-rolled strip steel coil needs to be unrolled by a rewinding unit and then flattened and transported by pressure rollers to facilitate subsequent sample cutting. Taking an automatic intelligent sampling system for cold-rolled strip steel disclosed in patent number 202110955926.6 as an example, the pressure rollers will attract a large amount of iron filings on their surface due to static electricity during operation. These iron filings will cause scratches on the surface of the cold-rolled strip steel when the pressure rollers are working, thus affecting the sample quality. At the same time, when cutting the cold-rolled strip steel, the existing cutting machine can only cut it into single-specification cold-rolled strip steel certification samples.

[0005] In conclusion, existing sampling devices all have certain defects and shortcomings, and there is still room for further improvement and perfection. Summary of the Invention

Detailed Implementation

[0032] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0033] It should be noted that in the description of this utility model, the terms "upper", "lower", "top", "bottom", "one side", "the other side", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not mean that the device or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0034] See appendix Figure 1-10 This paper presents a specific structure of an embodiment of a sampling device for cold-rolled strip steel certification proposed in this utility model. The device includes a strip steel conveying mechanism 100, a cutting mechanism 200, and a base 300; the base 300 is located between the strip steel conveying mechanism 100 and the cutting mechanism 200, and its two ends are respectively connected to the strip steel conveying mechanism 100 and the cutting mechanism 200. In this embodiment, three sets of conveying rollers 310 are rotatably connected between the left and right sides inside the working surface of the base 300 along the strip steel movement direction.

[0035] like Figure 3 As shown, the strip steel conveying mechanism includes a transport seat 101, side sliding grooves 102, a cylinder 103, a slide block 104, a transport roller 105, a first motor 106, a first conveying roller 107, a pressure roller 108, and a second motor 109. Side sliding grooves 102 are provided in the upper middle area of ​​both the left and right side walls of the transport seat 101. Slide blocks 104 are slidably connected to the inner walls of each side sliding groove 102. A pressure roller 108 is rotatably connected between the inner walls of the two slide blocks 104, allowing the slide blocks 104 to slide within the side sliding grooves 102, thereby driving the pressure roller 108 to slide. A second motor 109 is fixedly installed on the outer wall of one slide block 104, and the output shaft of the second motor 109 is coaxially fixed to one end of the pressure roller 108, enabling the pressure roller 108 to flatten the cold-rolled strip steel. Simultaneously, it cooperates with the transport roller 105 to achieve the purpose of conveying cold-rolled strip steel; cylinders 103 are fixedly installed on the top of both sides of the transport seat 101; the output end of the cylinder 103 is fixedly connected to the top of the corresponding slide 104; the transport roller 105 is rotatably connected between the middle of the inner walls on both sides of the transport seat 101, and the transport roller 105 is located directly below the pressure roller 108; a motor 106 is fixedly installed in the middle of the outer wall on one side of the transport seat 101, and the output shaft of the motor 106 is coaxially fixedly connected to one end of the transport roller 105; a working surface is provided in the middle of the front side of the transport seat 101, and its working surface is on the same horizontal plane as the working surface of the base 300; a transport roller 107 is rotatably connected to the inner side of the working surface of the transport seat 101.

[0036] Therefore, when it is necessary to take samples for certification of cold-rolled strip steel, the drive cylinder 103 drives the slide block 104 to move down, so that the pressure roller 108 connected to the slide block 104 cooperates with the transport roller 105 to press the cold-rolled strip steel sample to be cut. At this time, the drive motor 106 and the drive motor 109 simultaneously make the transport roller 105 and the pressure roller 108 rotate at the same speed but in opposite directions, so as to transport the cold-rolled strip steel.

[0037] In this embodiment, a chip removal component 110 is provided between the middle and front parts of the inner walls on both sides of the transport seat 101. When it is necessary to perform certification sampling on cold-rolled strip steel, the slide seat 104 is moved down so that the pressure roller 108 on the slide seat 104 cooperates with the transport roller 105 to flatten and transport the cold-rolled strip steel, which facilitates cutting and sampling. At the same time, the chip removal component 110 around the pressure roller 108 is used to remove iron filings on the pressure roller 108, so as to avoid the pressure roller 108 from scratching the sample during the sampling process.

[0038] like Figure 4-8 As shown, the dander removal assembly includes a drive shaft 111, a magnetic shielding cylinder 112, an electromagnet device 113, a conductive slip ring 114, a motor 115, a magnetic column 116, a magnetic sheet 117, and an adsorption cylinder 118. The drive shaft 111 is coaxially fixed to both ends of the magnetic column 116 and rotatably connected to the corresponding positions of the side walls of the transport seat 101, which supports the drive shaft 111. The magnetic shielding cylinder 112 and the electromagnet device 113 are coaxially fixed to the outer wall of the drive shaft 111 in sequence, with the electromagnet device 113 located inside the magnetic shielding cylinder 112. When energized, the electromagnet device 113 can generate magnetism. The magnetic shielding cylinder 112 has the function of isolating the magnetic field and can concentrate the magnetic field generated by the electromagnet device 113, thereby enhancing the magnetic influence of the electromagnet device 113 on the magnetic column 116. A conductive slip ring 114 is fixedly installed on the outer wall of the drive shaft 111. 114 is located outside the magnetic shielding shell 112, and the conductive slip ring 114 is electrically connected to the electromagnet device 113. The conductive slip ring 114 is connected to an external power source, which can then power the rotating electromagnet device 113. A motor 115 is fixedly installed on one side of the outer wall of the transport seat 101, and the output shaft of the motor 115 is coaxially connected to a transmission shaft 111 on one side. The magnetic column 116 has the same diameter as the transmission shaft 111, and the electromagnet device 113 can... The magnetic column 116 is affected by the magnetic column 116, and an adsorption cylinder 118 is sleeved on the outer wall of the magnetic column 116. Multiple sets of magnetic sheets 117 are fixedly installed on the inner wall of the adsorption cylinder 118. The inner walls of the magnetic sheets 117 are all fixedly connected to the outer wall of the magnetic column 116. That is, the magnetic column 116 and the adsorption cylinder 118 are fixedly connected by the magnetic sheets 117. The adsorption cylinder 118 has the same diameter as the magnetic shielding cylinder shell 112. The adsorption cylinder 118 is in movable contact with the side wall of the pressure roller 108.

[0039] The magnetic column 116, magnetic sheet 117 and adsorption cylinder 118 are all made of materials with high magnetic permeability and are not magnetic themselves.

[0040] In this embodiment, a sealing rail 120 is fixedly installed between the middle and front portions of the inner walls on both sides of the transport seat 101; one end wall of the sealing rail 120 contacts the adsorption cylinder 118; the sealing rail 120 is inclined, and the contact surface between the adsorption cylinder 118 and the sealing rail 120 is tangent; a slide rail 121 parallel to the adsorption cylinder 118 is fixedly installed on the inner wall of the sealing rail 120 corresponding to the adsorption cylinder 118; a screw 122 is correspondingly provided at the bottom of the slide rail 121, and the screw 122 is located in the middle of the sealing rail 120; both ends of the screw 122 are rotatably connected to the inner walls on both sides of the transport seat 101; the screw 122 is engaged with the upper... The device includes a scraper seat 123 that is slidably connected to a slide rail 121, which limits the movement of the scraper seat 123. The scraper seat 123 is slidably connected to the wall of the adsorption cylinder 118, and can scrape off iron filings from the surface of the adsorption cylinder 118. A motor 124 is fixedly installed on one side of the outer wall of the transport seat 101, and the output shaft of the motor 124 is coaxially fixed to one end of the screw 122. A collection groove 125 is provided on one side of the inner wall of the sealing rail 120. The collection groove 125 corresponds to the horizontal position of the scraper seat 123, so that the scraper seat 123 can transport the iron filings that have fallen off the surface of the adsorption cylinder 118 into the collection groove 125.

[0041] Therefore, when the pressure roller 108 is working and its surface is covered with iron filings, the drive motor 115 drives the transmission shaft 111 and the magnetic column 116 to rotate, thereby causing the magnetic sheet 117 fixed to the magnetic column 116 and the adsorption cylinder 118 to rotate, and their rotation direction is opposite to that of the pressure roller 108. At this time, the electromagnet device 113 is energized through the external power supply and the conductive slip ring 114, causing the electromagnet device 113 to generate a magnetic field. The generated magnetic field is concentrated in the magnetic column 116, the magnetic sheet 117 and the adsorption cylinder 118, thereby causing the surface of the adsorption cylinder 118 to become magnetic. Since the pressure roller 108 and the adsorption cylinder 118 rotate simultaneously and in opposite directions, the adsorption cylinder 118... The device can quickly and completely adsorb iron filings from the surface of the pressure roller 108. After the iron filings on the surface of the pressure roller 108 are adsorbed, the pressure roller 108 is lifted by the drive cylinder 103, so that the pressure roller 108 is separated from the surface of the adsorption cylinder 118. At this time, the electromagnet device 113 is de-energized by the external power supply, so that the magnetic field on the surface of the adsorption cylinder 118 disappears, and the iron filings on the surface of the adsorption cylinder 118 fall into the sealing rail 120. At the same time, the drive motor 124 drives the screw 122 to rotate, so that the scraper seat 123 on the screw 122 slides in the sealing rail 120, thereby scraping off the iron filings remaining on the adsorption cylinder 118, and pushing the iron filings on the sealing rail 120 into the collection groove 125.

[0042] like Figure 2 , 9 As shown in Figure -10, the cutting mechanism 200 includes: a cutting seat 210, a hydraulic cylinder unit 220, a cutting table 230, a slide rod 231, a positioning fixture 232, a longitudinal cutting blade 233, a transverse cutting blade 240, and a worktable 270; the cutting seat 210 is correspondingly disposed on the rear side of the base 300; the hydraulic cylinder unit 220 is fixedly mounted on the top of the cutting seat 210; the cutting table 230 is vertically slidably connected between the inner walls of the two sides of the cutting seat 210; the output end of the hydraulic cylinder unit 220 is fixedly connected to the top of the cutting table 230; the front end of the worktable 270 is correspondingly disposed below the cutting table 230 and connected to the rear end of the base 300, and the working surface of the worktable 270 is at the same horizontal plane as the working surface of the base 300; the middle of the inner walls of the left and right sides of the cutting table 230... Multiple sliding rods 231 are fixedly installed between the sections; several positioning clamps 232 are sequentially arranged on the sliding rods 231, with the positioning clamps 232 at both ends of the sliding rods 231 fixedly connected to the sliding rods 231, and the positioning clamps 232 in the middle area slidably connected to the sliding rods 231. The positioning clamps 232 have a self-locking function. After the position of the positioning clamps 232 on the sliding rods 231 is adjusted, the self-locking function of the positioning clamps 232 can fix the positioning clamps 232 in the corresponding positions on the sliding rods 231; the bottom of each positioning clamp 232 is engaged with a longitudinal cutting blade 233; a transverse cutting blade 240 is fixedly installed between the front sides of the inner walls on both sides of the cutting table 230; the bottoms of the transverse cutting blade 240 and the longitudinal cutting blade 233 are on the same horizontal plane. The transverse cutting blade 240 and the longitudinal cutting blade 233 can perform multi-scale cutting on cold-rolled strip steel.

[0043] In this embodiment, the hydraulic cylinder unit 220 consists of six hydraulic cylinders arranged in an array on the top of the cutting seat 210. All the hydraulic cylinders are arranged vertically, and their output ends are fixedly connected to the top of the cutting table 230.

[0044] An output roller 250 is rotatably connected between the left and right sides of the middle of the working surface of the worktable 270; a motor 260 is fixedly installed on one side of the middle of the worktable 270, and the output shaft of the motor 260 is coaxially fixedly connected to one end of the output roller 250.

[0045] The working surfaces of the base 300, transport seat 101, and cutting seat 210 are located on the same horizontal plane. When cutting the sample, the cold-rolled strip can move on the worktable formed by the base 300, transport seat 101, and cutting seat 210. The first conveyor roller 107 and the second conveyor roller 310 can facilitate the transmission of the cold-rolled strip and prevent the worktable from scratching the cold-rolled strip. After the cold-rolled strip is cut, the fifth drive motor 260 drives the output roller 250 to rotate, thereby outputting the cut cold-rolled strip sample.

[0046] The working principle of this application is as follows: When it is necessary to sample cold-rolled strip for certification, the drive cylinder 103 drives the slide block 104 to move downward, so that the pressure roller 108 connected to the slide block 104 cooperates with the transport roller 105 to press the cold-rolled strip sample to be cut. At this time, the drive motors 106 and 109 are driven simultaneously, so that the transport roller 105 and the pressure roller 108 rotate at the same speed but in opposite directions, thereby transporting the cold-rolled strip. The cold-rolled strip is transported to the worktable 270 through the base 300 and the second transport roller 310. At the same time, the cold-rolled strip is cut as needed. The strip steel sample specifications are determined by pulling the positioning clamps 232 on the slide bar 231 so that the spacing between two adjacent sets of positioning clamps 232 is the same as the required specifications. Then, the output end of the hydraulic cylinder unit 220 is driven to move the cutting table 230 downward, so that the longitudinal cutting blade 233 and the transverse cutting blade 240 at the bottom of the cutting table 230 cut the cold-rolled strip steel to form a cold-rolled strip steel certification sample that meets the requirements. After the cold-rolled strip steel is cut, the drive motor 260 drives the output roller 250 to rotate, thereby outputting the cut cold-rolled strip steel sample.

[0047] When the pressure roller 108 is working and its surface is covered with iron filings, the drive motor 115 drives the transmission shaft 111 and the magnetic column 116 to rotate. This, in turn, drives the magnetic sheet 117, which is fixed to the magnetic column 116, and the adsorption cylinder 118 to rotate in the opposite direction to the pressure roller 108. At this time, an external power supply and a conductive slip ring 114 energize the electromagnet device 113, causing it to generate a magnetic field. This magnetic field is concentrated within the magnetic column 116, the magnetic sheet 117, and the adsorption cylinder 118, thus magnetizing the surface of the adsorption cylinder 118. Because the pressure roller 108 and the adsorption cylinder 118 rotate simultaneously and in opposite directions, the adsorption cylinder 118 can quickly and completely adsorb the iron filings. After the iron filings on the surface of roller 108 are adsorbed, the roller 108 is lifted by the drive cylinder 103, so that the roller 108 is separated from the surface of the adsorption cylinder 118. At this time, the electromagnet device 113 is de-energized by the external power supply, so that the magnetic field on the surface of the adsorption cylinder 118 disappears, and the iron filings on the surface of the adsorption cylinder 118 fall into the sealing rail 120. At the same time, the drive motor 124 drives the screw 122 to rotate, so that the scraper seat 123 on the screw 122 slides in the sealing rail 120, thereby scraping off the iron filings remaining on the adsorption cylinder 118, and pushing the iron filings on the sealing rail 120 into the collection groove 125 to avoid scratching the surface of the cold-rolled strip steel during the sample cutting process.
