Description

Technical Field

[0001] The invention relates to the technical field of roller surface cleaning, and in particular to a double-layer scraper roller chip removal device and method for machine tools. Background Art

[0002] A roller machine is a mechanical device used to process metal or other materials. It mainly achieves forming or processing through the rotation and pressing of rollers. Its main uses include bending, forming and cutting of metal sheets. It is widely used in manufacturing, construction, automotive and other industries.

[0003] In the metal sheet forming process, in order to reduce the friction between the metal sheet and the roller, it is necessary to apply lubricating oil on the roller surface. After the lubricating oil rubs against the metal sheet, oil stains will be generated. In order to ensure the processing quality of the metal sheet, it is necessary to scrape off the oil stains on the metal sheet surface. For example, announcement number CN117259279B discloses a dipping machine roller cleaning device, which includes a cleaning box and a cleaning unit. A rubber roller is installed inside the cleaning box. A driver is connected to the cleaning box. The telescopic end of the driver is fixedly connected to the driving roller. The cleaning unit is arranged inside the cleaning box. The cleaning unit includes a support rod, a scraper and a support plate. The scraper is hinged on the support rod. The scraper corresponds to the rubber roller and is spaced apart from the rubber roller. A liquid spray pipe is installed on the scraper. The support plate is hinged on the support rod and used in conjunction with the scraper. A cleaning roller is installed on the support plate.

[0004] The device uses a scraper to scrape the rubber material on the rubber roller. Since the scraper and the rubber roller are spaced apart, the rubber will pass between the scraper and the rubber roller during scraping, resulting in incomplete scraping. At the same time, the rubber scraped off the scraper will adhere to the scraper. After long-term use, more and more rubber will be on the scraper, affecting the scraping efficiency of the scraper. The scraper needs to be cleaned regularly, which is cumbersome to operate. In addition, the rubber roller needs to be stopped during cleaning, affecting production efficiency.

[0005] Therefore, a novel double-layer scraper roller chip removal device and method for machine tools can be used to solve the shortcomings of the prior art. Summary of the invention

A magnetic plate is fixedly installed on the two columns, and the magnetic plate is located outside the dust cover. A magnetic block that cooperates with the magnetic plate is fixedly installed on the connecting rod.

[0020] The present invention also provides a double-layer scraper roller chip removal method for a machine tool, comprising the above-mentioned double-layer scraper roller chip removal device for a machine tool, and further comprising the following steps:

[0021] S1. First, place the metal sheet on the roller. Then, driven by the driving assembly, the roller will rotate on the stand to process the metal sheet. When the roller rotates, the supporting assembly will support the roller.

[0022] S2. When the roller rotates, the scraper will rotate around the rotating shaft through the pressing component on the chip removal part, so that the scraper always presses against the roller, and the scraper is used to scrape off the oil and dirt on the roller surface. In the process of scraping the oil and dirt, the rotating shaft is rotated by the separation component, so that one of the scrapers is separated from the roller, and the other scraper is attached to the roller. After running for a period of time, the separation mechanism is used again to change the operating state of the two scrapers, so that the scraper that was originally pressed against the roller is separated from the roller, and the scraper that was originally separated from the roller presses against the roller, so as to realize intermittent scraping operation;

[0023] S3. During the scraping process of the scraper, the cleaning component will absorb and collect the grease scraped off by the scraper. When the scraper that was originally against the roller is separated from the roller, the cleaning component will switch its form to carry out targeted cleaning of the grease adhered to the scraper and collect the cleaned grease to ensure that the scraper is in a clean state when it operates next time.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. When the double-layer scraper roller chip removal device for machine tools cleans the oil dirt on the roller surface, two scrapers are set to indirectly scrape the oil dirt on the roller. During the scraping and cleaning process, the vacuum cleaner will absorb and collect the oil dirt collected in the dust cover through the second pipe, which can ensure that the scraper is cleaned at the best time, thereby effectively removing dirt and impurities. At the same time, the clean roller surface can ensure the consistency and quality of processing and avoid defects caused by dirt.

[0026] 2. When the double-layer scraper roller chip removal device for machine tools is cleaning the grease on the roller surface, a separation component is set up, which can not only drive the rotating shaft to rotate to separate the scraper and the roller for intermittent operation, but also change the pressure between the scraper and the roller by fine-tuning the stroke of the separation component, so as to perform scraping with different strengths according to the viscosity of the grease, making the scraping efficiency of the scraper higher.

[0027] 3. When the double-layer scraper roller chip removal device for machine tools is cleaning the grease on the roller surface, the second motor and the bevel gear set are set to drive the screw to rotate, thereby driving the scraper on the connecting rod to operate through the nut and the limit slider, and the scraper is used to scrape off the grease adhering to the scraper, ensuring that the scraper is in a clean state before being put into operation.

[0028] 4. When the double-layer scraper roller chip removal device for machine tools is cleaning the grease on the roller surface, by setting the magnetic plate and the magnetic block, the baffle can be driven to move when the connecting rod moves to block the pipe two. At this time, the grease will not enter the vacuum cleaner from the pipe two, but enter the vacuum cleaner through the suction nozzle, the pipe three and the pipe one. The suction nozzle is used to specifically suck and clean the part being scraped by the scraper. The suction force is greater, the suction efficiency is higher, and the scraped grease is sucked more thoroughly.

[0029] To sum up, the present invention adopts a double-layer indirectly operating scraper to clean the surface of the roller, which has the advantages of high cleaning efficiency and more thorough cleaning. It cooperates with a vacuum cleaner to absorb the oil and dirt scraped off by the scraper, so that the scraper remains in a relatively clean state, thereby improving the scraping efficiency of the scraper. At the same time, the oil and dirt adhered to the stopped scraper can be further targetedly treated to further improve the cleanliness of the scraper, thereby improving the scraping efficiency of the scraper.

DETAILED DESCRIPTION

[0047] 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.

[0048] Example 1: Reference Figure 1-Figure 3 A double-layer scraper roller chip removal device for a machine tool includes a support base 1, and two vertical frames 8 fixedly mounted on the support base 1, and a side frame 6 is fixedly mounted on each of the two vertical frames 8; a shock-absorbing seat is fixedly mounted at the bottom of the support base 1 to reduce vibration during operation, thereby improving the operating efficiency of the roller 2.

[0049] The roller part includes a roller 2 rotatably mounted between two vertical frames 8 , a driving assembly and a supporting assembly. The driving assembly is used to drive the roller 2 to rotate, and the supporting assembly is used to support the roller 2 .

[0050] The driving assembly includes a motor 5 fixedly mounted on the support seat 1, a gear is fixedly mounted on the driving end of the motor 5, and a gear ring 4 meshing with the gear is fixedly mounted on the roller 2.

[0051] The rotation of the driving end of the motor 5 drives the gear fixedly connected to it to rotate, and the gear drives the gear ring 4 meshing with it to rotate. The rotation of the gear ring 4 drives the roller 2 fixedly connected to it to rotate. The purpose of using the gear and the gear ring 4 to drive the roller 2 to rotate is to improve the stability of the rotation of the roller 2 and reduce the influence of the eccentricity of the driving end of the motor 5 on the rotation of the roller 2. At the same time, the size of the gear can be freely changed to change the torque, so that the machine performs better in low-speed and high-torque applications.

[0052] The support assembly comprises a pad fixedly mounted on the support seat 1 , on which a support roller 7 is rotatably mounted, and on the roller 2 a support ring 3 abutting against the support roller 7 is fixedly mounted.

[0053] As the roller 2 rotates, the support ring 3 on the roller 2 will rotate on the support roller 7, and the friction force will drive the support roller 7 to rotate. The roller 2 and the stand 8 are rotatably connected through the bearing. By providing the support roller 7 and the support ring 3, the load on the bearing can be distributed, the negative pressure on the bearing can be reduced, the service life of the bearing can be effectively extended, and the operation of the roller 2 is smoother and more stable.

[0054] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 2 , Figure 4-Figure 15 , a chip removal part is used to clean the oil and dirt adhered to the surface of the roller 2. The chip removal part includes two rotating shafts 9 rotatably installed between the two side frames 6 through a connecting frame 19. The rotating shaft 9 is fixedly connected to the connecting frame 19, and the connecting frame 19 is rotatably connected to the side frame 6. A scraper 11 matching the roller 2 is fixedly installed on the two rotating shafts 9. A pressing assembly is installed between the side frame 6 and the rotating shaft 9, and one of the side frames 6 is equipped with two separation assemblies matching the corresponding connecting frame 19.

[0055] The protruding end of the connecting frame 19 is in the opposite direction to the scraper 11. Under the action of the pressing component, the connecting frame 19 will drive the rotating shaft 9 to rotate, so that the scraper 11 is pressed against the roller 2. As the roller 2 rotates, the scraper 11 will scrape off the oil and dirt adhered to the roller 2, so that the roller 2 remains clean.

[0056] The pressing assembly includes a limit column 18 fixedly mounted on the rotating shaft 9. The limit column 18 is arc-shaped, and the curvature of the limit column 18 is an arc about the rotating shaft 9. A counter plate 17 is fixedly mounted on the side frame 6. The limit column 18 and the counter plate 17 are slidably connected. A through hole matching the limit column 18 is provided on the counter plate 17. An arc spring 20 is fixedly mounted between the connecting frame 19 and the counter plate 17.

[0057] The arc spring 20 is in a compressed state, and under the action of the abutment plate 17, it will always abut against the connecting frame 19, so that the scraper 11 and the roller 2 abut against each other. The abutting force between the scraper 11 and the roller 2 can be changed by replacing the arc spring 20.

[0058] A through hole is provided on the connecting frame 19, and the limiting column 18 passes through the through hole. The limiting column 18 will slide in the through hole on the abutment plate 17 to ensure that the scraper 11 rotates around the rotating shaft 9. At the same time, in order to limit the arc spring 20 and prevent the arc spring 20 from deforming.

[0059] The separation component includes a telescopic cylinder 37 fixedly mounted on the side frame 6, and a wedge block 38 cooperating with the connecting frame 19 is fixedly mounted on the telescopic end of the telescopic cylinder 37. The wedge block 38 is pushed to move by the telescopic cylinder 37. Since the wedge block 38 adopts an inclined design, it will resist the connecting frame 19 when it moves, so that the connecting frame 19 has two states. In the first state, the wedge block 38 presses the connecting frame 19 but the scraper 11 is not separated from the roller 2. At this time, the connecting frame 19 will drive the rotating shaft 9 to rotate, changing the pressing force between the scraper 11 and the roller 2; in the second state, the wedge block 38 will press the connecting frame 19 to separate the scraper 11 from the roller 2, and at this time it plays the role of switching the scraper 11, thereby realizing the intermittent operation of the two scrapers 11.

[0060] In a further embodiment, two cleaning components cooperating with corresponding scrapers 11 are installed on the side frame 6, and the cleaning components include a limit rod 14 fixedly installed between the two side frames 6, a limit slider 21 is slidably installed on the limit rod 14, and a moving mechanism cooperating with the limit slider 21 is installed on the side frame 6.

[0061] The moving mechanism includes a screw rod 10 rotatably installed between two side frames 6, a motor 2 15 is fixedly installed on one of the side frames 6, the driving end of the motor 2 15 is connected to the screw rod 10 through a bevel gear set 16, a nut 22 is threadedly rotatably installed on the screw rod 10, and the nut 22 is fixedly connected to the limit slider 21.

[0062] The driving end of motor 2 15 rotates to drive the bevel gear set 16 to rotate, thereby driving the screw 10 to rotate. The rotation of the screw 10 drives the nut 22 to move, thereby driving the limit slider 21 to move. When the screw 10 rotates, there is no limit on the nut 22, so the nut 22 cannot move on the screw 10. At this time, the limit slider 21 is limited by the limit rod 14 to prevent the nut 22 from rotating. At the same time, the limit rod 14 also plays a certain supporting role, reducing the force on the screw 10, thereby protecting the screw 10 and extending the service life of the screw 10 and the nut 22.

[0063] A connecting rod 24 is fixedly mounted on the limit slider 21 , a V-shaped scraper 25 matched with the scraper 11 is fixedly mounted on the connecting rod 24 , and a collecting mechanism matched with the scraper 11 is mounted on the side frame 6 .

[0064] The screw rod 10 moves through the limit slider 21 to drive the connecting rod 24 to move, and the connecting rod 24 drives the scraper 25 to move. The scraper 25 is V-shaped. When the scraper 25 contacts the scraper 11, the scraper 25 will scrape off the oil and dirt adhered to the scraper 11. Due to the inclined design of the scraper 25 (refer to Fig.10 ), after being scraped, the grease will move along the inclined surface of the scraper 25 until the scraper 25 moves into the dust cover 26, thereby cleaning the grease on the scraper 11.

[0065] The collecting mechanism includes a collecting box 12 fixedly mounted on the side frame 6, a vacuum cleaner 13 fixedly mounted on the collecting box 12, the vacuum cleaner 13 and the collecting box 12 are connected via a conduit, a dust cover 26 fixedly mounted on the scraper 11, a suction pipe 27 fixedly mounted on the dust cover 26, the suction pipe 27 and the dust cover 26 are connected via a plurality of pipes 2 32, the vacuum cleaner 13 and the suction pipe 27 are connected via the suction pipe 1 23, and a switching structure matched with the plurality of pipes 2 32 is fixedly mounted inside the dust cover 26.

[0066] As the scraper 11 operates, the grease on the roller 2 will be scraped off by the scraper 11, and the grease on the scraper 11 will increase. Under the mutual pressure of the grease, the grease will enter the dust cover 26. At this time, the vacuum cleaner 13 will suck the grease in the dust cover 26 into the collection box 12 through the suction pipe 1 23, the suction pipe 27 and the multiple pipes 2 32 for collection.

[0067] At this time, the power of the vacuum cleaner 13 is fixed, and air is taken in from multiple pipes 2 32 at the same time. The air intake in each pipe 2 32 is the same and constant, so that the suction force at equal intervals in the dust cover 26 can be kept stable, which is convenient for sucking in oil and dirt.

[0068] The switching structure includes a pipe 3 3 fixedly mounted inside the dust cover 26, a groove body is provided on the pipe 3 33, a suction nozzle 35 connected with the pipe 3 33 is slidably mounted in the groove body, a telescopic cover 34 matched with the groove body is fixedly mounted on the suction nozzle 35, a magnetic stopper 36 matched with the connecting rod 24 is fixedly mounted on the suction nozzle 35, and the pipe 3 33 is connected with the suction pipe 2 27 through two pipes 1 28;

[0069] Two columns are slidably mounted on the dust cover 26, and a baffle 31 that matches with multiple pipes 32 is fixedly mounted on the two columns. The baffle 31 is located inside the dust cover 26. A magnetic plate 29 is fixedly mounted on the two columns. The magnetic plate 29 is located outside the dust cover 26, and a magnetic block 30 that matches with the magnetic plate 29 is fixedly mounted on the connecting rod 24.

[0070] As the scraper 25 moves, the magnetic block 30 on the connecting rod 24 will move above the magnetic plate 29. At this time, the suction force between the magnetic block 30 and the magnetic plate 29 is greater than the gravity of the magnetic plate 29 and the baffle 31. The baffle 31 will move up under the action of the magnetic plate 29 to block the pipe two 32. At this time, the vacuum cleaner 13 cannot absorb the grease through the pipe two 32, but absorbs the grease through the pipe one 28, the pipe three 33 and the suction nozzle 35.

[0071] In addition, as the scraper 25 moves, the connecting rod 24 moves and counteracts the magnetic blocking rod 36 (the connecting rod 24 is made of iron material and attracts the magnetic blocking rod 36), which will drive the magnetic blocking rod 36 to move. The movement of the magnetic blocking rod 36 will drive the suction nozzle 35 to move. The suction nozzle 35 will move synchronously with the movement of the scraper 25 to absorb the grease just scraped off by the scraper 25, so as to achieve the purpose of targeted absorption and cleaning. The function of the telescopic cover 34 is to block the tank body to avoid air leakage. The telescopic cover 34 is an existing telescopic cover body, which will not be specifically described here, similar to the S-shaped folding shutter;

[0072] The power of the vacuum cleaner 13 is fixed, and the air intake from multiple pipes 32 is changed to air intake from a single suction nozzle 35. When the air intake volume remains unchanged, the suction nozzle 35 has a greater suction force, and the suction is more thorough and clean.

[0073] The specific operation steps of this device are as follows:

[0074] The arc spring 20 is in a compressed state, and under the action of the abutment plate 17, it will always abut against the connecting frame 19, so that the scraper 11 and the roller 2 abut against each other, and as the roller 2 rotates, the scraper 11 will scrape off the grease on the roller 2. During the scraping process, as the scraper 11 operates, the grease on the roller 2 will be scraped off by the scraper 11, and the grease on the scraper 11 will increase. Under the mutual pressure of the grease, the grease will enter the dust cover 26. At this time, the vacuum cleaner 13 will suck the grease in the dust cover 26 into the collection box 12 through the suction pipe 1 23, the suction pipe 2 27 and the plurality of pipes 2 32 for collection.

[0075] Changing the pressing force between the scraper 11 and the roller 2: The wedge block 38 is pushed to move by the telescopic cylinder 37. Since the wedge block 38 is designed to be inclined, it will contact the connecting frame 19 when it moves, so that the connecting frame 19 has two states. The wedge block 38 presses the connecting frame 19, but the scraper 11 and the roller 2 are not separated. At this time, the connecting frame 19 will drive the rotating shaft 9 to rotate, changing the pressing force between the scraper 11 and the roller 2;

[0076] The scraper 11 is separated from the roller 2 to achieve intermittent operation of the two scrapers 11: the wedge block 38 is pushed to move by the telescopic cylinder 37, and the wedge block 38 presses the connecting frame 19 to separate the scraper 11 from the roller 2. At this time, the scraper 11 is switched to achieve intermittent operation of the two scrapers 11.

[0077] When one of the scrapers 11 is separated from the roller 2: the driving end of the second motor 15 rotates to drive the bevel gear set 16 to rotate, thereby driving the screw rod 10 to rotate, the screw rod 10 rotates to drive the nut 22 to move, thereby driving the limit slider 21 to move, the screw rod 10 moves through the limit slider 21 to drive the connecting rod 24 to move, the connecting rod 24 drives the scraper 25 to move, the scraper 25 is V-shaped, as the scraper 25 contacts the scraper 11, the scraper 25 will scrape off the grease adhered to the scraper 11, and the grease will move along the inclined surface of the scraper 25 after being scraped off, until the scraper 25 moves into the dust cover 26, so as to clean the grease on the scraper 11;

[0078] At the same time, with the movement of the scraper 25, the magnetic block 30 on the connecting rod 24 will move above the magnetic plate 29. At this time, the suction force between the magnetic block 30 and the magnetic plate 29 is greater than the gravity of the magnetic plate 29 and the baffle 31. The baffle 31 will move up under the action of the magnetic plate 29 to block the pipe two 32. At this time, the vacuum cleaner 13 cannot absorb the grease through the pipe two 32, but absorbs the grease through the pipe one 28, the pipe three 33 and the suction nozzle 35. The movement of the connecting rod 24 will counteract the magnetic baffle 36 (the connecting rod 24 is made of iron and is attracted to the magnetic baffle 36), which will drive the magnetic baffle 36 to move. The movement of the magnetic baffle 36 will drive the suction nozzle 35 to move. The suction nozzle 35 will move synchronously with the scraper 25 to specifically absorb the grease just scraped off by the scraper 25.

[0079] 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.

7. A double-layer scraper roller chip removal method for machine tools, used for the double-layer scraper roller chip removal device for machine tools as claimed in any one of claims 1 to 6, characterized in that: The following steps are involved: S1. First, a metal sheet is placed on a roller (2). Then, driven by a driving component, the roller (2) rotates on a stand (8) to perform a processing operation on the metal sheet. When the roller (2) rotates, the roller (2) is supported by a supporting component. S2, when the roller (2) rotates, the scraper (11) is rotated around the rotating shaft (9) through the pressing component on the chip removal part, so that the scraper (11) always contacts the roller (2), and the scraper (11) is used to scrape off the oil dirt on the surface of the roller (2). In the process of scraping off the oil dirt, the rotating shaft (9) is rotated by the separation component, so that one of the scrapers (11) is separated from the roller (2), and the other scraper (11) is attached to the roller (2). After running for a period of time, the separation mechanism is used to change the operating state of the two scrapers (11) again, so that the scraper (11) originally contacting the roller (2) is separated from the roller (2), and the scraper (11) originally separated from the roller (2) contacts the roller (2), thereby realizing intermittent scraping operation; S3. During the scraping process of the scraper (11), the cleaning component absorbs and collects the oil and dirt scraped off by the scraper (11). When the scraper (11) that was originally in contact with the roller (2) is separated from the roller (2), the cleaning component switches its form to perform targeted cleaning of the oil and dirt adhered to the scraper (11) and collects the cleaned oil and dirt, thereby ensuring that the scraper (11) is in a clean state when it is operated next time.
