[0043] The material guiding mechanism 1 includes a material guiding box 101, which is located below the waste chip discharge port of the roll grinder. The upper part of the material guiding box 101 is open, and the upper opening is aligned with the waste chip discharge port of the roll grinder. A discharge port 102 is provided on one side of the material guiding box 101, and the inner bottom of the material guiding box 101 is a slope 103 structure.

[0044] See also Figure 2 , 3 As shown, a metal chip filtering mechanism 2 is used to filter metal chips in roller grinding waste. The metal chip filtering mechanism 2 includes a first filter box 201, a feed port 202 is provided on one side of the first filter box 201, and the feed port 202 is sealed and connected with the discharge port 102. It also includes a mounting frame 203 fixedly installed on the grinding machine, a mounting groove 2031 is provided at the bottom of the mounting frame 203, and first bearings 2032 are fixedly installed at both ends of the inner part of the mounting groove 2031, and screws 2033 are fixedly installed in the inner rings of the two first bearings 2032. A screw sleeve 2034 is threadedly installed on the screw 2033. A drive motor 2035 is fixedly installed on one side of the mounting frame 203, and the output shaft of the drive motor 2035 is fixedly connected to one end of the screw 2033. A first hydraulic cylinder 204 is fixedly installed on the screw sleeve 2034, and a sealing box 205 is fixedly connected to the telescopic end of the first hydraulic cylinder 204. A first electromagnetic suction cup 2053 is sealed and installed inside the sealing box 205.

[0045] See also Figure 5 , 6 As shown, the paper fiber filtering mechanism 3 is used to filter paper fibers in the roller grinding waste.

[0046] The paper fiber filtering mechanism 3 includes a second filter box 301, one side of which is connected to the first filter box 201 through a connecting pipe 302, a second hydraulic cylinder 303 is fixedly installed at the bottom of the second filter box 301, the telescopic end of the second hydraulic cylinder 303 extends into the interior of the second filter box 301 and is fixedly connected to a support plate 304, a lower liquid hole 3041 is opened on the support plate 304, a first filter screen 305 is clamped on the support plate 304, and when the first filter screen 305 is filtering, its installation height is lower than the height of the discharge port of the connecting pipe 302;

[0047] See also Figure 5 As shown, the coolant circulation mechanism 4 is used to recover and circulate the coolant used for roller grinding heat dissipation.

[0048] The coolant circulation mechanism 4 includes an infusion pipe 401, one end of which is connected to the lower part of the second filter box 301, and the other end is connected to the heat exchanger 402. A circulation pump 403 is fixedly installed on the infusion pipe 401, and the discharge port of the heat exchanger 402 is fixedly connected to a circulation pipe 405, and one end of the circulation pipe 405 is connected to the coolant spray part at the grinding position of the grinder.

[0049] Through the above technical scheme, the feed box 101 in the feed mechanism 1 can quickly collect the waste generated by roller grinding, and its slope 103 structure ensures that the waste slides smoothly to the discharge port 102 and enters the first filter box 201. The screw 2033, the screw sleeve 2034, the drive motor 2035 and the first hydraulic cylinder 204 on the mounting frame 203 work together to accurately control the position of the first electromagnetic suction cup in the sealing box 205. When a certain amount of metal waste is deposited at the bottom of the first filter box 201, the sealing box 205 extends into the bottom of the first filter box 201 to absorb the metal waste, which can efficiently recover the metal waste and prevent the metal waste from circulating in the coolant to cause blockage of the cooling system and wear of the equipment.

[0050] In the paper fiber filtering mechanism 3, the second filter box 301 receives the material after preliminary filtration through the connecting pipe 302, and the second hydraulic cylinder 303 at the bottom can flexibly lift and lower the support plate 304. During filtering, the first filter screen 305 made of glass fiber on the support plate 304 can effectively intercept paper fibers with high filtration accuracy. When the filter screen is blocked, the support plate 304 can be lifted by the second hydraulic cylinder 303, so that the first filter screen 305 can be conveniently taken out for cleaning or replacement, thereby ensuring continuous and efficient paper fiber filtration, reducing the impact of paper fibers on subsequent coolant circulation, and avoiding fibers from being entangled in equipment components and affecting the normal operation of the equipment.

[0051] The coolant circulation mechanism 4 has an infusion pipe 401, a circulation pump 403 and a heat exchanger 402 that work in perfect harmony. The circulation pump 403 provides power to ensure that the coolant is stably transported from the second filter box 301 to the heat exchanger 402. The heat exchanger 402 dissipates heat efficiently, so that the coolant temperature is appropriate and accurately flows back to the grinding spray parts of the grinder through the circulation pipe 405, providing continuous and stable cooling guarantee for the roller grinding, preventing the roller from being damaged due to overheating, and improving the processing accuracy and surface quality of the roller. The heat exchanger 402 uses existing technology and equipment.

[0052] See also Figure 4 As shown, the sealed box 205 includes a box body 2051 and a box cover 2052, a first electromagnetic suction cup 2053 is embedded in the interior of the box body 2051, a magnetic surface of the first electromagnetic suction cup 2053 is in contact with the inner bottom of the box body 2051, the box cover 2052 and the box body 2051 are fixedly connected by bolts 2054, and a rubber pad 2055 is provided at the connection between the box cover 2052 and the box body 2051.

[0053] Through the above technical solution, the combined structure of the box body 2051 and the box cover 2052 provides a relatively closed installation environment for the first electromagnetic suction cup 2053, which can prevent external substances such as coolant and grinding waste from directly contacting the first electromagnetic suction cup 2053, and avoid the first electromagnetic suction cup 2053 being damaged by short circuit, corrosion and the like due to the entry of liquid. In addition, the box cover 2052 and the box body 2051 are fixed by bolts 2054. The above connection method facilitates the installation and disassembly of the first electromagnetic suction cup 2053. The box body 2051 and the box cover 2052 are preferably made of stainless steel. Stainless steel has good corrosion resistance and mechanical strength, can withstand certain external force impact and chemical erosion, and ensure the structural integrity of the sealed box.

[0054] Aeration pipes 209 are fixedly connected to both sides of the lower portion of the first filter box 201 .

[0055] By injecting gas into the coolant in the first filter box 201 through the aeration pipe 209, the paper fibers that have sunk to the bottom of the first filter box 201 can be re-suspended in the coolant, thereby improving the filtering effect on the paper fibers. The bubbles generated by the aeration pipe 209 can re-suspend the precipitated metal chips in the coolant, so that the metal chips can better contact with the first electromagnetic suction cup 2053, thereby facilitating the first electromagnetic suction cup 2053 to adsorb them.

[0056] See also Figure 2As shown, a mounting cavity 207 is provided inside the bottom of the first filter box 201, and a second electromagnetic chuck 208 is installed inside the mounting cavity 207, and the magnetic attraction surface of the second electromagnetic chuck 208 is in contact with the top of the mounting cavity 207. The second electromagnetic chuck 208 can magnetically attract the metal scraps deposited in the first filter box 201, thereby preventing the metal scraps from entering the second filter box 301 along with the coolant, thereby improving the filtering quality.

[0057] See also Figure 5 As shown, a second bearing 3031 is fixedly installed on the inner bottom of the second filter box 301, and the telescopic end of the second hydraulic cylinder 303 is fixedly installed in the inner ring of the second bearing 3031. The second bearing 3031 is a sealed bearing, which can ensure the sealing of the output of the second hydraulic cylinder 303. The installation of the second bearing 3031 provides a stable support point for the second hydraulic cylinder 303, preventing the telescopic end of the second hydraulic cylinder 303 from being offset or damaged due to uneven force.

[0058] A third bearing 307 is fixedly installed on the inner bottom of the second filter box 301 . A limiting rod 3071 is movably installed in the inner ring of the third bearing 307 . The upper end of the limiting rod 3071 is fixedly connected to the bottom of the support plate 304 .

[0059] When the support plate 304 rises or falls, the limit rod 3071 moves in the inner ring of the third bearing 307, providing a precise vertical movement guide for the support plate 304, so that the support plate 304 can only move in the vertical direction, avoiding unnecessary displacement in the horizontal direction, and ensuring the stability and accuracy of the support plate 304 during the lifting process.

[0060] The first filter screen 305 is a glass fiber screen, and lifting rings 306 are fixedly installed at both ends of the first filter screen 305 .

[0061] Through the above technical solution, the glass fiber mesh has good filtering accuracy. Its fibers are fine and can effectively intercept paper fibers in the roller grinding waste and capture tiny fiber particles, ensuring that paper fiber impurities in the coolant are filtered out to the maximum extent, preventing paper fibers from entering the coolant circulation mechanism 4 and causing blockage and damage. When the first filter screen 305 is blocked and needs to be cleaned or replaced, the lifting ring 306 provides a convenient fulcrum, allowing the operator to quickly and safely remove the first filter screen 305 from the support plate 304.

[0062] See also Figure 5 , 7As shown, a filter box 404 is fixedly connected to the infusion tube 401, and the filter box 404 is located between the circulation pump 403 and the heat exchanger 402. The filter box 404 includes an installation box body, and the interior of the installation box body is sequentially installed with a second filter screen 4041, a third filter screen 4042 and a fourth filter screen 4043, the second filter screen 4041 is located at the liquid inlet of the filter box 404, the fourth filter screen 4043 is located at the liquid outlet of the filter box 404, and the third filter screen 4042 is located between the second filter screen 4041 and the fourth filter screen 4043; the second filter screen 4041 is a magnetic filter screen, the third filter screen 4042 is a polyester fiber screen, and the fourth filter screen 4043 is a sintered filter screen.

[0063] By integrating multiple filter screens in the filter box 404 on the infusion tube 401, the second filter screen 4041 with a magnetic structure can preferentially absorb ferromagnetic impurities in the coolant, the third filter screen 4042 with a polyester fiber structure can further intercept tiny particles and suspended matter, and the fourth filter screen 4043 with a sintered structure performs ultimate fine filtration to ensure that the coolant is extremely pure, avoid impurities from accumulating in the cooling system, corroding equipment components or scratching rollers, thereby extending the service life of the equipment and reducing maintenance costs.

[0064] See also Figure 3 As shown, the metal chip filtering mechanism 2 further includes a material collecting box 206 , which is placed on one side of the first filtering box 201 . The upper portion of the material collecting box 206 is open, and the size of the opening of the material collecting box 206 is larger than the size of the sealing box 205 .

[0065] The collection box 206 collects metal chips adsorbed by the first electromagnetic suction cup 2053. Since it is placed on one side of the first filter box 201 and has an open top, when the sealing box 205 moves to the top of the collection box 206, the first electromagnetic suction cup 2053 is powered off to allow the metal chips to smoothly fall from the sealing box 205 into the collection box 206. The design of the opening size being larger than the size of the sealing box 205 ensures that the metal chips can completely fall into the collection box 206 during the unloading process, thereby preventing the metal chips from falling outside and causing incomplete collection and pollution of the working area.

[0066] When the embodiment of the present invention is used, the roller grinder is started, and the waste generated during the grinding process falls into the feed box 101 of the feed mechanism 1 through the waste chip outlet. The slope 103 structure at the bottom of the feed box 101 allows the waste to slide smoothly to the outlet 102, and then enter the first filter box 201 of the metal chip filtering mechanism 2. The aeration pipe 209 in the first filter box 201 is opened to disturb the coolant to prevent paper fiber deposition. The metal waste is deposited and adsorbed on the bottom of the first filter box 201 under the action of the second electromagnetic suction cup 208, and the cooling oil with paper fibers enters the second filter box 301 of the paper fiber filtering mechanism 3 through the connecting pipe 302. When it is necessary to clean the metal chips at the bottom of the first filter box 201, the second electromagnetic suction cup 208 is first powered off to make the metal chips at the bottom of the first filter box 201 free. Under the coordinated action of the drive motor 2035 and the first hydraulic cylinder 204, the first electromagnetic suction cup 2053 drives the screw 2033 and the screw sleeve 2034 to extend the sealing box 205 into the first filter box 201 and close to the metal chips. The metal chips at the bottom of the first filter box 201 are adsorbed on the bottom of the sealing box 205 and are moved out to the outside of the first filter box 201 for cleaning under the coordinated action of the drive motor 2035 and the first hydraulic cylinder 204. The coolant filtered by the metal chips enters the second filter box 301 of the paper fiber filtering mechanism 3 through the connecting pipe 302. When the coolant flows through the first filter screen 305 on the support plate 304, the paper fibers are intercepted on the first filter screen 305, and the coolant continues to flow downward through the lower liquid hole 3041 on the support plate 304 and accumulates at the bottom of the second filter box 301. The filtered coolant enters the coolant circulation mechanism 4 through the infusion pipe 401, and the circulation pump 403 is started to transport the coolant to the filter box 404, and is further finely filtered through the magnetic filter screen, polyester fiber mesh and sintered filter screen in turn to remove the remaining tiny impurities. The coolant after fine filtration enters the heat exchanger 402, and heat exchange is carried out in the heat exchanger 402. After the coolant temperature is reduced, it returns to the coolant spray part at the grinding position of the grinder through the circulation pipe 405 to cool the roller, and the cycle is repeated.

[0067] When the filtering effect of the first filter screen 305 decreases, the filtering speed slows down significantly, or a large amount of paper fibers pass through the coolant, the support plate 304 is lifted by the second hydraulic cylinder 303, and the first filter screen 305 is taken out by the lifting ring 306 for cleaning or replacement. The cleaned first filter screen 305 can be reinstalled on the support plate 304 by the lifting ring 306, and the support plate 304 is lowered to continue filtering.

[0068] The above shows and describes the basic principle of the present invention. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. The above embodiments and descriptions in the specification only illustrate the principle of the present invention. Without departing from the scope of the present invention, any modifications, equivalent substitutions and improvements made within the scope of the present invention should be included in the protection scope of the present invention.
