Description

Technical Field

[0001] This application relates to the field of metal sheet processing technology, specifically a cleaning and drying device for metal sheets. Background Technology

[0002] In the metal processing industry, after metal sheets undergo processing, their surfaces are often covered with various stains and impurities, such as metal shavings, oil, and dust. Effective cleaning and drying are essential steps to ensure the quality of subsequent processing and to meet product usage requirements.

[0003] Chinese utility model patent CN220371684U discloses a cleaning and drying device for metal plates. It achieves thorough drying of the metal plates through symmetrical suction pipes and air outlet pipes, enhances the cleaning ability through symmetrical water spray pipes and wiping rollers, and improves the practicality and stability of the device through springs and guide / exit plates. However, this device directly transports the metal plates to the water spray pipes for rinsing. Large metal plates often have a lot of metal debris adhering to their surface during processing. Due to the high hardness of the metal debris, under the direct impact of the sprayed water, the metal debris is pushed by the water flow and slides on the plate surface. During this sliding process, its sharp edges or corners easily scratch the surface of the metal plate, forming linear scratches, which not only damages the metal plate but also reduces the cleaning quality.

[0004] Therefore, this application provides a cleaning and drying apparatus for metal plates to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a cleaning and drying device for metal plates, which aims to solve the problems mentioned in the background art. When large metal plates are directly transported to the water spray pipe for rinsing, the high-hardness metal debris attached to the surface of the plate will slide under the push of the water flow due to direct spray rinsing. The sharp edges or corners of the debris will easily scratch the surface of the plate, forming linear scratches, which will damage the plate and reduce the cleaning quality.

[0006] To achieve the above objectives, this application provides the following technical solution: a cleaning and drying device for metal plates, comprising a fixed box, a conveying structure disposed on the fixed box, and a cleaning mechanism and a drying mechanism disposed on the conveying structure for sequentially cleaning and drying the metal plates. The cleaning and drying device further comprises a chip removal structure disposed on the conveying structure and located on the side of the cleaning mechanism away from the drying mechanism for removing metal debris from the surface of the metal plates to be cleaned.

[0007] The chip removal structure includes brackets symmetrically arranged on the conveying structure, a magnetic roller rotatably connected between the two brackets for magnetically attracting metal debris from the surface of the metal sheet to be cleaned, and a transmission assembly disposed at one end of the magnetic roller and connected to the conveying structure for transmitting power from the conveying structure to the magnetic roller. By setting up the chip removal structure, metal debris on the surface of the metal sheet can be magnetically removed by the magnetic roller before the metal sheet enters the cleaning mechanism, preventing metal debris from entering the subsequent cleaning process and causing scratch damage to the metal sheet, effectively protecting the surface of the metal sheet and improving cleaning quality. Simultaneously, the transmission assembly can transmit the power of the conveying structure during operation to the magnetic roller, causing the magnetic roller to rotate synchronously with the conveying structure. This design eliminates the need for additional power equipment to drive the magnetic roller, reducing energy consumption caused by the operation of additional power equipment.

[0008] Preferably, to achieve the conveying of metal sheets, the conveying structure includes fixed frames symmetrically fixedly mounted on the fixed box, drive rollers symmetrically rotatably connected between the two fixed frames, a conveyor belt disposed on the two drive rollers, a motor fixedly mounted on one side of one of the fixed frames for driving the rotation of one of the drive rollers, and a support roller rotatably connected between the two fixed frames and located between the two drive rollers for supporting the conveyor belt. The two drive rollers are connected and transmit power through the conveyor belt, which is made of metal mesh. Multiple conveyor belts are located inside the conveyor belt, and two supports are fixedly connected to the two fixed frames respectively. By driving one drive roller to rotate through the motor, and since the two drive rollers are connected through the conveyor belt, the other drive roller will also rotate, thereby realizing the cyclic movement of the conveyor belt and thus conveying the metal sheets from one position to another, meeting the transfer requirements of the metal sheets between different processing steps.

[0009] Preferably, to achieve the cleaning of the metal sheet, the cleaning mechanism includes a protective cover fixedly installed on two fixed frames and located above the conveyor belt, a water spray pipe fixedly installed inside the protective cover, a water pump fixedly installed on the top of the protective cover, a water suction pipe and a water delivery pipe respectively fixedly connected to both ends of the water pump, and a water tank located on one side of the fixed frame. The end of the water suction pipe away from the water pump is fixedly connected to the water tank, and the end of the water delivery pipe away from the water pump is fixedly connected to the water spray pipe. The protective cover is located on one side of the magnetic roller. When the water pump is started, cleaning water is drawn from the water tank through the water suction pipe, and then the water is delivered to the water spray pipe through the water delivery pipe. The water spray pipe then sprays the water onto the surface of the metal sheet located on the conveyor belt, thereby cleaning the metal sheet, removing dirt and impurities from the surface of the metal sheet, improving the cleanliness of the metal sheet, and providing a good foundation for subsequent processing steps.

[0010] Preferably, in order to dry the metal sheet, the drying mechanism includes a heat-insulating cover fixedly installed on the two fixed frames and located on the side of the protective cover away from the magnetic roller, and a fan fixedly installed on the top of the heat-insulating cover and arranged in a linear array; by blowing air into the heat-insulating cover by the fan, the air flow is accelerated, which can make the moisture on the surface of the metal sheet evaporate quickly, thereby achieving the drying effect, removing the moisture on the surface of the metal sheet, avoiding the adverse effects of moisture residue on the metal sheet such as corrosion, and improving production efficiency.

[0011] Preferably, in order to realize the power transmission between the drive roller and the magnetic drum, the transmission assembly includes a synchronous pulley fixedly sleeved on one of the drive rollers at the end away from the motor and the other at the end of the magnetic drum, and a synchronous belt disposed on the two synchronous pulleys. The two synchronous pulleys are connected and transmit power through the synchronous belt. With this design, when the drive roller rotates, the magnetic drum can be driven to rotate synchronously through the transmission of the synchronous belt and the two synchronous pulleys, so that there is no need to set up an additional power device to drive the magnetic drum to rotate, thus reducing the energy consumption caused by the operation of an additional power device.

[0012] Preferably, to facilitate the removal of metal debris adsorbed on the surface of the magnetic roller, the debris removal structure further includes a non-magnetic groove formed on one side of the magnetic roller surface and a scraper fixedly installed on the two supports near the protective cover and in contact with the magnetic roller surface for scraping away the magnetically attracted metal debris. With this design, when the magnetic roller rotates, the scraper can scrape away the metal debris adsorbed on the magnetic roller surface. As the magnetic roller rotates, the non-magnetic groove rotates to the scraper position. The non-magnetic groove is non-magnetic, and the originally magnetically attracted metal debris loses its magnetic attraction. Under the scraping action of the scraper, it detaches from the magnetic roller and falls onto the scraper, thereby achieving the separation of metal debris from the magnetic roller surface. This prevents the accumulation of metal debris from affecting the magnetic roller's adsorption capacity and ensures that the magnetic roller always maintains a good working condition.

[0013] Preferably, to facilitate the discharge of metal debris from the scraper, the scraper surface has an inclined surface that slopes towards one end of one of the supports, and one of the supports has a chip discharge groove communicating with the inclined surface for chip removal. With this design, when metal debris falls onto the scraper, it can be manually pushed periodically. Guided by the inclined surface, the metal debris can be smoothly pushed into the chip discharge groove and then discharged from the equipment. This allows for regular cleaning of the metal debris on the scraper, preventing the accumulation of metal debris from affecting the normal operation of the scraper, ensuring stable operation of the equipment and good chip removal effect.

[0014] The cleaning and drying device for metal plates is equipped with a chip removal structure. Before the metal plates enter the cleaning mechanism, the magnetic rollers can magnetically remove metal chips from the surface of the metal plates, preventing metal chips from entering the subsequent cleaning process and causing scratch damage to the metal plates. This effectively protects the surface of the metal plates and improves the cleaning quality.

[0015] The metal plate cleaning and drying device can transmit the power of the conveying structure to the magnetic roller through the transmission component, so that the magnetic roller rotates synchronously with the operation of the conveying structure. This design eliminates the need for additional power equipment such as motors to drive the magnetic roller, which simplifies the structure of the device and reduces the number of parts.

[0016] This metal plate cleaning and drying device, through the design of non-magnetic grooves and scrapers, can separate metal debris from the surface of the magnetic roller, avoiding the accumulation of metal debris that affects the magnetic roller's adsorption capacity and ensuring that the magnetic roller always maintains a good working condition. At the same time, through the design of inclined surfaces and chip removal grooves, metal debris on the scraper can be cleaned regularly, preventing the accumulation of metal debris from affecting the normal operation of the scraper, ensuring stable operation of the equipment and good chip removal effect.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Example 1

[0030] This embodiment provides a cleaning and drying device for metal plates, such as... Figures 1-5 As shown, the cleaning and drying device includes a fixed box 1, a conveying structure 2 mounted on the fixed box 1, and a cleaning mechanism 3 and a drying mechanism 4 mounted on the conveying structure 2 for sequentially cleaning and drying metal plates. The cleaning and drying device also includes a chip removal structure 5 mounted on the conveying structure 2 and located on the side of the cleaning mechanism 3 away from the drying mechanism 4 for removing metal debris from the surface of the metal plates to be cleaned. The chip removal structure 5 includes brackets 51 symmetrically mounted on the conveying structure 2, a magnetic roller 52 rotatably connected between the two brackets 51 for magnetically attracting metal debris from the surface of the metal plates to be cleaned, and a transmission assembly 53 mounted at one end of the magnetic roller 52 and connected to the conveying structure 2 for transmitting power from the conveying structure 2 to the magnetic roller 52.

[0031] In use, the metal sheet to be cleaned is first placed on the conveyor structure 2. The conveyor structure 2 is started to move the metal sheet. The metal sheet will first reach the chip removal structure 5. At this time, the magnetic roller 52, which is connected between the two supports 51, uses its own magnetism to magnetically attract the metal debris on the surface of the metal sheet to be cleaned below. However, when the conveyor structure 2 is started, the power of the conveyor structure 2 can be transmitted to the magnetic roller 52 through the transmission component 53, so that the magnetic roller 52 and the conveyor structure 2 operate synchronously, ensuring that the magnetic roller 52 can continuously and effectively remove chips from the surface of the metal sheet. After that, the chip-removed metal sheet will continue to move on the conveyor structure 2, and it will pass through the cleaning mechanism 3 and the drying mechanism 4 in sequence to complete the cleaning and drying process. Meanwhile, the magnetic roller 52 continues to rotate between the supports 51, continuously attracting metal debris from the surface of subsequent metal sheets, and finally obtaining a clean and dry metal sheet.

[0032] Specifically, the conveying structure 2 includes a fixed frame 21 symmetrically fixedly installed on the fixed box 1, a transmission roller 22 symmetrically rotatably connected between the two fixed frames 21, a conveyor belt 23 set on the two transmission rollers 22, a motor fixedly installed on one side of one of the fixed frames 21 for driving the rotation of one of the transmission rollers 22, and a support roller 24 rotatably connected between the two fixed frames 21 and located between the two transmission rollers 22 for supporting the conveyor belt 23. The two transmission rollers 22 are connected and transmit power through the conveyor belt 23. The conveyor belt 23 is made of metal mesh. Multiple conveyor belts 23 are located inside the conveyor belt 23. Two brackets 51 are fixedly connected to the two fixed frames 21 respectively.

[0033] When cleaning and drying metal sheets are required, the motor is first started to drive one of the connected drive rollers 22 to rotate. Since the two drive rollers 22 are connected and power is transmitted between them by a metal mesh conveyor belt 23, the rotation of the drive roller 22 will drive the conveyor belt 23 to move in a cycle, thereby causing the other drive roller 22 to rotate as well. The multiple support rollers 24, which are rotatably connected between the two fixed frames 21 and located between the two drive rollers 22, will support the conveyor belt 23, ensuring that the conveyor belt 23 remains stable during operation and preventing excessive sagging due to the placement or movement of metal sheets. The metal plate to be cleaned is then placed on the conveyor belt 23, which moves with the conveyor belt 23 and sequentially transports the chip removal structure 5, the cleaning mechanism 3, and the drying mechanism 4 to complete chip removal, cleaning, and drying. The two fixed frames 21, which are symmetrically fixed on the fixed box 1, provide a stable support frame for the entire conveying structure 2. At the same time, the two brackets 51, which are fixedly connected to the two fixed frames 21 respectively, provide the installation base for the magnetic roller 52 and other components in the subsequent chip removal structure 5, so that the magnetic roller 52 can be in a suitable position to adsorb and remove metal debris from the surface of the metal plate moving on the conveyor belt 23.

[0034] Furthermore, the cleaning mechanism 3 includes a protective cover 31 fixedly installed on two fixed frames 21 and located above the conveyor belt 23, a water spray pipe 32 fixedly installed inside the protective cover 31, a water pump 33 fixedly installed on the top of the protective cover 31, a water suction pipe 34 and a conveying pipe 35 fixedly connected to both ends of the water pump 33, and a water tank 36 located on one side of the fixed box 1. The end of the water suction pipe 34 away from the water pump 33 is fixedly connected to the water tank 36, and the end of the conveying pipe 35 away from the water pump 33 is fixedly connected to the water spray pipe 32. The protective cover 31 is located on one side of the magnetic roller 52.

[0035] When the metal sheet moves from the conveyor belt 23 of the conveyor structure 2 to the cleaning mechanism 3, the water pump 33 is started. Since the protective cover 31 is fixedly installed on the two fixed frames 21 and located above the conveyor belt 23, when the metal sheet is inside the protective cover 31, the water pump 33 draws cleaning water from the water tank 36 located on one side of the fixed box 1 through the water suction pipe 34 fixedly connected at one end. After the water pump 33 pressurizes the water, it will be transported through the conveying pipe 35 fixedly connected at the other end to the spray pipe 32 fixedly installed inside the protective cover 31. The spray pipe 32 can then spray the cleaning water onto the metal sheet located inside the protective cover 31 to rinse the surface of the metal sheet. During this process, the protective cover 31 can prevent the cleaning water from splashing everywhere, ensuring that the cleaning process proceeds in an orderly manner. Moreover, the protective cover 31 is located on one side of the magnetic roller 52, so that the metal sheet is first de-scraped by the chip removal structure 5 before entering the cleaning stage. At the same time, the water tank 36 provides water reserves for the cleaning process.

[0036] Furthermore, the drying mechanism 4 includes a heat preservation cover 41 fixedly mounted on two fixed frames 21 and located on the side of the protective cover 31 away from the magnetic roller 52, and a fan 42 fixedly mounted on the top of the heat preservation cover 41 and arranged in a linear array.

[0037] After cleaning, the metal plates continue to move along the conveyor belt 23 of the conveyor structure 2. When they reach the drying mechanism 4, the heat insulation cover 41 is fixedly installed on two fixed frames 21 and located on the side of the protective cover 31 away from the magnetic roller 52. However, during the metal plate conveying process, multiple fans 42 are started, and the multiple fans 42 can blow hot air into the heat insulation cover 41. When the metal plates enter the heat insulation cover 41, the hot air can be concentrated on the surface of the metal plates, accelerating the evaporation of moisture on the surface of the metal plates, thereby quickly drying the cleaned metal plates for subsequent processing or collection.

[0038] Furthermore, the transmission assembly 53 includes a synchronous pulley 531 that is fixedly sleeved on one of the transmission rollers 22 at the end away from the motor and the end away from the magnetic roller 52, and a synchronous belt 532 disposed on the two synchronous pulleys 531. The two synchronous pulleys 531 are connected and transmit power through the synchronous belt 532.

[0039] When the motor in the conveying structure 2 drives one of the transmission rollers 22 to rotate, the synchronous pulleys 531, which are fixedly sleeved in the transmission assembly 53 at the end of one of the transmission rollers 22 away from the motor and the end of the magnetic drum 52, are connected and transmit power through the synchronous belts 532 set on the two synchronous pulleys 531. At this time, the rotating transmission roller 22 drives the synchronous pulleys 531 on it to rotate. The synchronous pulleys 531 then transmit power to the synchronous pulleys 531 at one end of the magnetic drum 52 through the synchronous belts 532, thereby driving the magnetic drum 52 to rotate. This allows the magnetic drum 52 to operate synchronously with the transmission roller 22 of the conveying structure 2, thus eliminating the need for additional power equipment to drive the magnetic drum to rotate and reducing the energy consumption caused by the operation of additional power equipment.

[0040] Example 2

[0041] Unlike Example 1, as Figure 3 and Figure 5 As shown, in order to facilitate the removal of metal debris adsorbed on the surface of the magnetic roller 52, the chip removal structure 5 also includes a non-magnetic groove 54 opened on one side of the surface of the magnetic roller 52 and a scraper 55 fixedly installed on the side of the two supports 51 near the protective cover 31 and in contact with the surface of the magnetic roller 52 for scraping off the metal debris magnetically adsorbed on the surface of the magnetic roller 52.

[0042] When the magnetic roller 52 rotates continuously under the drive of the transmission component 53 to adsorb metal debris on the surface of the metal plate to be cleaned, the scraper 55, which is fixedly installed on the side of the two brackets 51 near the protective cover 31, is always in contact with the surface of the magnetic roller 52 and scrapes the metal debris magnetically attracted to its surface. As the magnetic roller 52 continues to rotate, the non-magnetic groove 54 opened on one side of its surface rotates to the position of the scraper 55. Since the non-magnetic groove 54 is not magnetic, the magnetic attraction of the metal debris originally scraped to this area by the scraper 55 is weakened. As the magnetic roller 52 continues to rotate, the scraper 55 continues to contact the surface of the magnetic roller 52. After the metal debris loses its magnetic attraction, it is scraped by the scraper 55 to the vicinity of the non-magnetic groove 54 and falls onto the scraper 55, thus preventing the metal debris from continuously adhering to the surface of the magnetic roller 52 and ensuring that the magnetic roller 52 can continuously and efficiently adsorb metal debris on the surface of the metal plate.

[0043] In order to facilitate the discharge of metal debris from the scraper 55, the surface of the scraper 55 has an inclined surface 551 that slopes towards one end of one of the supports 51. One of the supports 51 has a chip discharge groove 511 that communicates with the inclined surface 551 for chip removal. With this design, when metal debris falls onto the scraper 55, the metal debris on the scraper 55 can be pushed manually at regular intervals. Guided by the inclined surface 551, the metal debris can be smoothly pushed to the chip discharge groove 511 and then discharged from the equipment. This timely cleaning of the metal debris on the scraper 55 prevents the accumulation of metal debris from affecting the normal operation of the scraper 55, ensuring the stable operation of the equipment and a good chip removal effect.

[0044] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
