Description

Technical Field

[0001] The invention relates to the technical field of cold rolling equipment, and in particular to a sampling device for cold rolled strip steel certification. Background Art

[0002] Cold rolled strip steel refers to strip steel and thin plates made from hot rolled strip steel and steel plates by cold rolling mill at room temperature.

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

[0004] During the sampling process of cold-rolled strip, the rewinding unit needs to open the cold-rolled strip coil and flatten it through rollers for transportation to facilitate subsequent sample cutting. Taking an automatic intelligent sampling system for cold-rolled strip disclosed with patent number 202110955926.6 as an example, the roller will absorb a large amount of iron filings on the surface of the roller due to static electricity during operation. These iron filings will cause scratches on the surface of the cold-rolled strip when the roller is working, thereby affecting the sample quality. At the same time, when cutting the cold-rolled strip, the existing cutting machine can only cut into cold-rolled strip certification samples of a single specification.

[0039] The magnetic conductive column 116, the magnetic conductive sheet 117 and the adsorption tube 118 are all made of materials with high magnetic conductivity and are not magnetic themselves.

[0040] In this embodiment, a sealing rail 120 is fixedly installed between the middle front parts of the inner walls on both sides of the transport seat 101; the end wall of one side of the sealing rail 120 is in contact with the adsorption cylinder 118; the sealing rail 120 is set at an inclination, and the contact surface of the adsorption cylinder 118 and the sealing rail 120 is tangent; the inner wall of the sealing rail 120 on the side corresponding to the adsorption cylinder 118 is fixedly installed with a slide 121 arranged parallel to the adsorption cylinder 118; a screw 122 is correspondingly provided at the bottom of the slide 121, and the screw 122 is located in the middle of the sealing rail 120; the two ends of the screw 122 are correspondingly rotatably connected to the inner walls on both sides of the transport seat 101; the meshing on the screw 122 A scraper seat 123 is provided and the scraper seat 123 is slidably connected to a slideway 121, and the slideway 121 limits the movement of the scraper seat 123; the scraper seat 123 is slidably connected to the wall of the adsorption cylinder 118, and the scraper seat 123 can scrape off the iron filings on the surface of the adsorption cylinder 118; a motor 4 124 is fixedly mounted on the outer wall of one side of the transport seat 101, and the output shaft of the motor 4 124 is coaxially fixedly connected to one end of the screw 122; a receiving groove 125 is provided on the inner wall of one side of the sealing rail 120; the receiving groove 125 corresponds to the horizontal position of the scraper seat 123, so that the scraper seat 123 can transport the iron filings that fall off the surface of the adsorption cylinder 118 to the receiving groove 125.

[0041] Therefore, when the pressure roller 108 is working and iron filings are attached to its surface, the driving motor 115 drives the transmission shaft 111 and the magnetic column 116 to rotate, thereby driving the magnetic sheet 117 and the adsorption cylinder 118 fixed to the magnetic column 116 to rotate, and at the same time, the 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, so that the electromagnet device 113 generates a magnetic field, and the generated magnetic field is collected in the magnetic column 116, the magnetic sheet 117 and the adsorption cylinder 118, so that magnetism is generated on the surface of the adsorption cylinder 118. Since the pressure roller 108 and the adsorption cylinder 118 rotate at the same time and in opposite directions, the adsorption cylinder 118 It is capable of quickly and completely adsorbing the iron filings on the surface of the pressure roller 108. After the adsorption of the iron filings on the surface of the pressure roller 108 is completed, the pressure roller 108 is lifted by driving the cylinder 103, so that the pressure roller 108 is separated from the surface of the adsorption cylinder 118.

At the same time, the driving 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 remaining iron filings on the adsorption cylinder 118, and at the same time pushing the iron filings on the sealing rail 120 into the receiving groove 125.

[0046] The working principle of the present application is as follows: when it is necessary to sample the cold-rolled steel strip for certification, the cylinder 103 is driven to drive the slide 104 downward, so that the pressure roller 108 connected to the slide 104 cooperates with the transport roller 105, so as to press the cold-rolled steel strip sample to be cut. At this time, the motor 106 and the motor 2 109 are driven at the same time, so that the transport roller 105 and the pressure roller 108 have the same rotation speed and opposite direction, so that the cold-rolled steel strip can be transported, and the cold-rolled steel strip is transported to the workbench 270 through the base 300 and the transport roller 2 310. At the same time, the cold-rolled steel strip that needs to be cut is The specification of the strip steel sample is determined by pulling the positioning fixture 232 on the slide bar 231 so that the spacing between the two adjacent groups of positioning fixtures 232 is the same as the required specification. Thereafter, the hydraulic cylinder unit 220 is driven to drive the cutting table 230 downward at its output end, so that the longitudinal cutting knife 233 and the transverse cutting knife 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 cutting of the cold-rolled strip steel is completed, the motor 5 260 is driven to drive the output roller 250 to rotate, so that the cold-rolled strip steel sample after cutting is output.

[0047] When the pressure roller 108 is working and iron filings are attached to its surface, the driving motor 115 drives the transmission shaft 111 and the magnetic column 116 to rotate, thereby driving the magnetic sheet 117 and the adsorption cylinder 118 fixed to the magnetic column 116 to rotate, and at the same time, the 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, so that the electromagnet device 113 generates a magnetic field, and the generated magnetic field is collected in the magnetic column 116, the magnetic sheet 117 and the adsorption cylinder 118, so that magnetism is generated on the surface of the adsorption cylinder 118. Since the pressure roller 108 and the adsorption cylinder 118 rotate at the same time and in opposite directions, the adsorption cylinder 118 can quickly and completely adsorb the pressure roller 108. Iron filings on the surface of roller 108. After the iron filings on the surface of pressure roller 108 are adsorbed, pressure roller 108 is lifted by driving cylinder 103, so that pressure roller 108 is separated from the surface of adsorption cylinder 118. At this time, the electromagnet device 113 is powered off by an external power supply, so that the magnetic field on the surface of adsorption cylinder 118 disappears, thereby causing the iron filings on the surface of adsorption cylinder 118 to fall into the sealing rail 120. At the same time, motor 4 124 is driven to drive screw 122 to rotate, so that scraper seat 123 on screw 122 slides in sealing rail 120, thereby scraping off the remaining iron filings on adsorption cylinder 118, and at the same time, the iron filings on sealing rail 120 are pushed into storage slot 125, so as to avoid scratching the surface of cold-rolled strip during sample cutting.
