[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The embodiment of the present invention provides a production device for galvanized sheet, such as Figure 1-11 As shown, the production device of galvanized sheet includes: a roller conveyor 1 and a box body 2 installed on the roller conveyor 1; a mounting plate 3 fixedly installed in the box body 2, on which two groups of first cleaning brushes 4 for rotating and scrubbing impurities on the surface of the galvanized sheet are rotatably installed; a fixed plate 5 fixedly installed in the box body 2, under which a second cleaning brush 6 for sliding back and forth and scrubbing impurities on the surface of the galvanized sheet is provided; a first driving mechanism provided on the box body 2 for driving the two groups of the first cleaning brushes 4 to rotate; and a second driving mechanism provided on the box body 2 for driving the second cleaning brush 6 to move.

[0022] In this embodiment, the galvanized sheet is conveyed by the roller conveyor 1. When the galvanized sheet enters the box 2, two groups of first cleaning brushes 4 start to rotate and brush the surface of the galvanized sheet. This rotating brushing method helps to remove most of the impurities on the surface of the galvanized sheet, especially for flat or relatively flat surfaces. At the same time, the second cleaning brush 6 performs a back-and-forth reciprocating brushing operation on the surface of the galvanized sheet. This step is mainly aimed at the detailed parts that are difficult to clean with a rotating brush, such as the groove part of the corrugated galvanized sheet. The sliding brush moves back and forth to ensure that every corner can be fully cleaned. By combining the rotary brushing and the sliding brushing, the device can comprehensively and efficiently clean various impurities on the surface of the galvanized sheet, especially for galvanized sheets with complex shapes (such as corrugated shapes). Good cleaning effects can be achieved. Through the coordinated action of the roller conveyor 1, the first drive mechanism and the second drive mechanism, the entire cleaning process is highly automated, reducing manual intervention and improving processing efficiency. At the same time, the device is not only suitable for cleaning flat galvanized sheets, but can also effectively deal with galvanized sheets with complex shapes, such as rolled shapes, rectangular printed shapes and corrugated shapes, etc., and has strong versatility and adaptability.

[0023] In a further preferred embodiment of the present invention, the first driving mechanism includes: first sprockets 7 fixedly mounted on a group of the cleaning brush 4 rotating shafts; a first chain 8 mounted on a group of the first sprockets 7 for synchronously driving a group of the first cleaning brushes 4 to rotate, the first chain 8 being meshed with a group of the first sprockets 7; a rotating rod 9 rotatably mounted on one side of the inner wall of the box body 2; a bevel gear 10 fixedly mounted on the rotating rod 9 and the rotating shaft of any first sprocket 7, the two bevel gears 10 being meshed with each other; a group of connecting gears 11 provided at the other end of the rotating rod 9 and one side of the box body 2, the group of connecting gears 11 being meshed with each other; a motor 12 fixedly mounted on one side of the box body 2 for driving the first cleaning brush 4 to rotate, the output shaft of the motor 12 being meshed with the rotating rod 9.

[0024] In this embodiment, first, the motor 12 is started, so that the output shaft of the motor 12 starts to rotate, and the rotational force is transmitted to the two groups of rotating rods 9 through a group of connecting gears 11 meshing with the rotating rods 9. Due to the meshing action of the connecting gears 11, the two groups of rotating rods 9 will rotate synchronously in opposite directions. Then, the bevel gears 10 on the two groups of rotating rods 9 start meshing transmission, and the rotational force is transmitted to the rotating shafts of the first sprockets 7 of each corresponding group. Then, the first chain 8 sleeved on the first sprocket 7 starts meshing transmission. Due to the continuity and rigidity of the chain, it can be ensured that multiple first sprockets in a group The rotating shaft of a cleaning brush 4 rotates synchronously, so that a group of first cleaning brushes 4 can rotate and brush the surface of the galvanized sheet at the same speed and direction. Afterwards, under the continuous conveyance of the roller conveyor 1, the galvanized sheet enters the box 2 and is brushed by the rotating first cleaning brush 4. Impurities on the surface are effectively removed. Through the coordinated action of the first sprocket 7, the first chain 8, the rotating rod 9, the bevel gear 10 and the connecting gear 11, efficient and synchronous driving of a group of first cleaning brushes 4 is achieved. This design not only improves the cleaning efficiency, but also ensures the uniformity of the cleaning quality.

[0025] In a further preferred embodiment of the present invention, the second driving mechanism includes: a support plate 13 fixedly mounted on the top of the fixed plate 5; a disc 14 rotatably mounted on the support plate 13, and an eccentric seat 15 is mounted on the disc 14; a connecting frame 16 slidably sleeved on the eccentric seat 15 for driving the second cleaning brush 6 to move, and a guide block 17 is fixedly mounted on the bottom of the connecting frame 16, and the guide block 17 is detachably connected to the second cleaning brush 6; a connecting mechanism provided on the disc 14 and the connecting gear 11 for synchronously driving the disc 14 and the first cleaning brush 4 to rotate.

[0026] In this embodiment, when the motor 12 starts and drives the first cleaning brush 4 to rotate, the disc 14 will also rotate synchronously through the operation of the connecting mechanism. Since the eccentric seat 15 is far away from the center position of the disc 14, when the disc 14 rotates, the eccentric seat 15 will move along a circular trajectory. This eccentric design is the key to the second driving mechanism to achieve forward and backward sliding cleaning. The connecting frame 16 is vertically sleeved on the eccentric seat 15 and slides with it. Therefore, when the eccentric seat 15 moves along the circular trajectory, the connecting frame 16 will move left and right accordingly. At the same time, due to the sliding relationship between the connecting frame 16 and the eccentric seat 15, the eccentric seat 15 will also slide up and down in the connecting frame 16. When the connecting frame 16 moves left and right, the second cleaning brush 6 will also reciprocate back and forth along the surface of the galvanized sheet to achieve deep cleaning of its surface. Through the synergistic effect of the eccentric seat 15 and the connecting frame 16, the second cleaning brush 6 can reciprocate back and forth along the surface of the galvanized sheet, and combined with the rotating washing of the first cleaning brush 4, a comprehensive and efficient cleaning of the surface of the galvanized sheet is achieved.

[0027] In a further preferred embodiment of the present invention, a connection port for the guide block 17 to slide forward and backward is formed on the fixing plate 5 , and a guide rod 18 is fixedly installed in the connection port, and the guide rod 18 passes through the guide block 17 .

[0028] In this embodiment, when the disc 14 rotates and drives the eccentric seat 15 to move, the connecting frame 16 moves left and right accordingly, and at the same time the guide block 17 slides back and forth along the guide rod 18. The sliding of the guide block 17 drives the second cleaning brush 6 detachably connected thereto to reciprocate back and forth, which, combined with the rotating washing of the first cleaning brush 4, achieves comprehensive and efficient cleaning of the surface of the galvanized sheet.

[0029] In a further preferred embodiment of the present invention, the connecting mechanism includes: a connecting rod 19 rotatably installed in the box body 2; a second sprocket 20 fixedly mounted on the connecting rod 19 and the rotating shaft of the disc 14, respectively, and a second chain 21 is mounted on the two second sprockets 20; a differential wheel 22 fixedly mounted on any one end of the connecting gear 11 and the connecting rod 19, respectively; and a belt 23 mounted on a group of the differential wheels 22 for synchronously driving the first cleaning brush 4 and the connecting rod 9 to rotate.

[0030] In this embodiment, since the second cleaning brush 6 is synchronously driven by multiple discs 14 and the connecting frame 16, the multiple discs 14 are connected by the connecting rod 19, the second sprocket and the second chain, so that when the connecting rod 19 rotates, the multiple discs 14 are synchronously rotated through the setting of the chain. In addition, when the first cleaning brush 4 rotates, its connecting gear 11 will rotate synchronously, and the rotation of the connecting gear 11 is transmitted to the connecting rod 19 through the differential wheel 22 and the belt 23, thereby rotating the connecting rod 19. At the same time, the differential action of the differential wheel 22 enables the connecting rod 19 to obtain a higher rotation speed, thereby improving the washing efficiency of the second cleaning brush 6. The design of the chain drive and the differential wheel 22 ensures efficient transmission and conversion of power, so that the second cleaning brush 6 can slide back and forth quickly to perform more effective washing operations on the surface of the galvanized sheet.

[0031] In a further preferred embodiment of the present invention, a connecting plate is fixedly installed in the box body 2, an electric telescopic rod 24 is fixedly installed at the bottom of the connecting plate, a guide wheel 25 for limiting and guiding the galvanized sheet is installed on the electric telescopic rod 24, and water retaining strips are provided on the inlet and outlet of the box body 2.

[0032] In this embodiment, the galvanized sheet is conveyed into the box body 2 by the roller conveyor 1. After receiving the signal, the electric telescopic rod 24 starts to slide down and drives the guide wheel 25 to slide down to the surface of the galvanized sheet. After the guide wheel 25 contacts the surface of the galvanized sheet, it starts to guide it to ensure that the galvanized sheet moves along a predetermined path during the washing process. At the same time, the limiting mechanism installed on the inner wall of the roller conveyor 1 limits the galvanized sheet to prevent it from swinging or deviating during the washing process. The water retaining bar prevents the waste water generated during the washing process from overflowing, thereby keeping the working environment clean. Through the setting of the guide wheel 25 and the limiting mechanism, the stability and accuracy of the galvanized sheet during the washing process are ensured, and the washing effect is improved. Through the precise control of the electric telescopic rod 24, the guide wheel 25 can accurately contact the surface of the galvanized sheet, thereby achieving precise guidance of the galvanized sheet.

[0033] In a further preferred embodiment of the present invention, a group of drainage pipes 26 for flushing impurities on the surface of the galvanized sheet are fixedly installed in the box body 2, a water tank 27 is arranged under the roller conveyor 1, a first water pump 28 is installed in the water tank 27, and a connecting pipe 29 is fixedly installed on one side of the box body 2, and the connecting pipe 29 is connected to the drainage end of the first water pump 28 and the group of drainage pipes 26.

[0034] In this embodiment, while the first cleaning brush 4 and the second cleaning brush 6 are cleaning the galvanized sheet, the first water pump 28 is started to pump out the water in the water tank 27 and transport it to the drain pipe 26 through the connecting pipe 29. The drain pipe 26 sprays the water evenly on the surface of the galvanized sheet to flush the impurities. At the same time, the galvanized sheet is mechanically cleaned by the first cleaning brush 4 and the second cleaning brush 6, and the impurities are removed from the surface of the galvanized sheet together with the flushing water. The waste water after flushing is discharged through the drain pipe. The introduction of the flushing function further improves the cleaning effect of the surface of the galvanized sheet, and can more thoroughly remove impurities and stains. The uniform spraying design of the drain pipe 26 ensures that the water can cover the entire surface of the galvanized sheet, thereby improving the uniformity and efficiency of flushing.

[0035] In a further preferred embodiment of the present invention, a water-proof silicone plate 30 is fixedly installed in the box body 2, and the water-proof silicone plate 30 is located on one side of the second cleaning brush 6.

[0036] In this embodiment, the waterproof silicone plate 30 effectively isolates the flushing water to prevent it from splashing into the dewatering area, thereby keeping the working environment clean. By scraping off water stains with the waterproof silicone plate 30 in close contact with the surface of the galvanized sheet, the cleaning effect can be effectively improved.

[0037] In a further preferred embodiment of the present invention, a sponge roller 31 for removing water droplets on the galvanized plate is rotatably installed in the box body 2, and the sponge roller 31 is located on one side of the waterproof silicone plate 30. A third sprocket 32 ​​is fixedly sleeved on the rotating shaft of the sponge roller 31 and the differential wheel 22, and a group of the third sprockets 32 are sleeved with a third chain 33.

[0038] In this embodiment, when the motor 12 is started, its rotational force is transmitted to the differential wheel 22 on the connecting rod 19 through the first drive mechanism and the second drive mechanism. While the differential wheel 22 rotates, it drives the third sprocket 32 ​​fixed on its rotating shaft to rotate synchronously. Through the transmission action of the third chain 33, the third sprocket on the sponge roller 31 connected to the third sprocket 32 ​​on the differential wheel 22 also starts to rotate, thereby realizing the synchronous rotation of the sponge roller 31 and the differential wheel 22. The rotating sponge roller 31 contacts the galvanized sheet after the water stains are scraped off by the waterproof silicone plate 30, absorbs the water droplets on its surface, and ensures that the galvanized sheet remains in a relatively dry state when leaving the equipment.

[0039] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments: In another embodiment of the present invention, a squeezing roller 34 for squeezing water out of the sponge roller 31 is rotatably installed in the box body 2, and the squeezing roller 34 is in close contact with the sponge roller 31. A differential gear 36 is fixedly sleeved on the rotating shafts of the squeezing roller 34 and the sponge roller 31, and the two differential gears 36 are meshed with each other. A water guide plate 35 is fixedly installed in the box body 2, and the water guide plate 35 is located below the squeezing roller 34. A scraper 37 for scraping water drops on the squeezing roller 34 is installed on the water guide plate 35.

[0040] In this embodiment, while the sponge roller 31 rotates, the squeezing roller 34 is caused to rotate synchronously through the setting of the differential gear 36. The squeezing roller 34 squeezes out the water in the sponge roller 31, and then guides the water through the water guide plate 35 so that it is directly discharged to the bottom of the inner shell of the roller conveyor 1, and then discharged through the drain pipe. The design of the squeezing roller 34 and the differential gear 36 realizes the automatic squeezing and discharge of the water in the sponge roller 31, maintains the dry state of the sponge roller 31, and improves its ability to absorb water droplets. The design of the water guide plate 35 and the scraper 37 ensures the effective collection and discharge of water.

[0041] In another embodiment of the present invention, a filtering mechanism for filtering cleaning water is provided in the water tank 27, and the filtering mechanism includes: a partition 38 fixedly installed in the water tank 27; the partition 38 separates the water tank 27 into a water storage chamber and a filter chamber; a group of filter plates 39 slidably installed in the filter chamber for filtering impurities in the cleaning water; a connecting box 40 fixedly installed at the bottom of the roller conveyor 1 for collecting cleaning water, and the sewage pipe of the connecting box 40 is connected to the filter chamber of the water tank 27; a second water pump 41 fixedly installed at the bottom of the filter chamber for transporting water in the filter chamber to the water storage chamber, and the discharge end of the second water pump 41 extends into the water storage chamber.

[0042] In this embodiment, during the surface cleaning of the galvanized sheet, the cleaning water discharged from the drain pipe 26 is collected by the connecting box 40, and the collected cleaning water is discharged into the filter chamber of the water tank 27 through the sewage pipe. In the filter chamber, multiple filter plates 39 filter impurities in the cleaning water to remove suspended matter, particulate matter and other impurities. The filtered clean water is transported to the water storage chamber for storage through the suction action of the second water pump 41. When the cleaning water needs to be used again, the first water pump 28 is started to transport the water in the water storage chamber back to the drain pipe 26 for spraying and cleaning. Through this circulation process, the recycling of cleaning water is realized, and the utilization efficiency of water resources is improved. Through the introduction of the filtering mechanism, the recycling of cleaning water is realized, and the production cost and water resource consumption are reduced.

[0043] In another embodiment of the present invention, a cleaning mechanism for cleaning impurities on the filter plate 39 is provided in the filter chamber, and the cleaning mechanism includes: multiple groups of fourth sprockets 42 rotatably installed in the filter chamber; fourth chains 43 respectively mounted on the multiple groups of fourth sprockets 42, and a third cleaning brush 44 for cleaning impurities on the filter plate 39 is installed on the fourth chain 43; and a linkage mechanism provided on the multiple groups of fourth sprockets 42 and the rotating shaft on the connecting gear 11.

[0044] In this embodiment, when it is necessary to clean the impurities on the filter plate 39, the linkage mechanism starts to work, and it transmits the rotational force of the connecting gear 11 to the fourth sprocket 42, so that the fourth sprocket 42 starts to rotate. As the fourth sprocket 42 rotates, the fourth chain 43 also starts to move. Since the third cleaning brush 44 is installed on the fourth chain 43, the third cleaning brush 44 also rotates with the movement of the chain. The rotating third cleaning brush 44 fits tightly against the surface of the filter plate 39, and the impurities attached to the filter plate 39 are brushed off through the friction between the bristles and the filter plate 39. The brushed impurities flow into the collection box 50 along with the cleaning water to collect the impurities.

[0045] In another embodiment of the present invention, the linkage mechanism includes: fifth sprockets 45 fixedly mounted on the rotating shafts of the plurality of fourth sprockets 42, and the plurality of fifth sprockets 45 are each provided with a fifth chain 46; sixth sprockets 47 fixedly mounted on the rotating shafts of any one of the driven gears 11 and the fifth sprocket 45, and the two sixth sprockets 47 are provided with a sixth chain 48.

[0046] In this embodiment, when the motor 12 is started and drives the connecting gear 11 to rotate, the rotational force of the connecting gear 11 is transmitted to any fifth sprocket 45 through the sixth sprocket 47 and the sixth chain 48. The fifth sprocket 45 that receives the rotational force starts to rotate and transmits the rotational force to other fifth sprockets 45 through the fifth chain 46, thereby realizing the synchronous rotation of multiple fifth sprockets 45. Since the rotating shafts of the multiple fourth sprockets 42 are respectively fixedly connected to the multiple fifth sprockets 45, the multiple fourth sprockets 42 also rotate synchronously with the rotation of the fifth sprocket 45. The rotating fourth sprocket 42 drives the fourth chain 43 to move, thereby driving the third cleaning brush 44 installed on the fourth chain 43 to rotate, so as to clean the filter plate 39. Through this linkage process, the synchronous operation of multiple cleaning mechanisms is realized, thereby improving the cleaning efficiency and automation level of the equipment.

[0047] In another embodiment of the present invention, an L-shaped plate 49 is fixedly installed at the bottom of the filter plate 39, and a collection box 50 for collecting impurities cleaned from the filter plate 39 is slidably installed on the L-shaped plate 49, and a protective cover 51 for protecting the motor 12, the connecting gear 11 and the sixth chain is installed on one side of the box body 2.

[0048] In this embodiment, when the third cleaning brush 44 rotates and cleans impurities on the filter plate 39 under the drive of the fourth chain 43, the impurities are brushed into the collection box 50, and the collection box 50 is located on the L-shaped plate 49. As the impurities accumulate, the user can pull out the collection box 50 for cleaning at any time to ensure the continuous and stable operation of the equipment. At the same time, the protective cover 51 protects key components such as the motor 12, the connecting gear 11 and the sixth chain to prevent them from being disturbed or damaged by the external environment, thereby improving the reliability and safety of the equipment.

[0049] The present invention also provides a production process for producing a galvanized sheet using the above-mentioned galvanized sheet production device, comprising the following steps: Step 1: Use the roller conveyor 1 to smoothly and continuously convey the pre-treated galvanized sheet into the box 2. When the galvanized sheet enters the box 2, the first cleaning brush 4 and the second cleaning brush 6 start to work to mechanically clean the surface of the galvanized sheet to remove residual stains, rust, etc.; Step 2: Spray flushing water onto the surface of the galvanized sheet through the drain pipe 26 to flush out impurities. At the same time, the waterproof silicone plate 30 isolates the flushing water to prevent it from splashing into the dewatering area. When the galvanized sheet passes through the waterproof silicone plate 30, its soft edge will cling to the surface of the galvanized sheet to scrape off residual water stains and impurities, providing convenience for subsequent dewatering operations.

[0050] Step 3: After the motor 12 is started, the sponge roller 31 is driven to rotate through the differential wheel 22, the third sprocket 32 ​​and the third chain 33. The rotating sponge roller 31 contacts the galvanized sheet and absorbs water droplets on its surface to ensure that the galvanized sheet remains in a relatively dry state when leaving the equipment.

[0051] Step 4: After the above cleaning and water removal steps, the galvanized sheet can enter the subsequent processing stage.

[0052] In summary, compared with related technologies, this device can achieve efficient and comprehensive cleaning of impurities on the surface of galvanized sheets, thereby significantly improving the surface quality of galvanized sheets and reducing subsequent processing problems or product quality defects caused by residual impurities.
