It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0019] The embodiment of the present invention provides a production process and device for a galvanized sheet of a washing machine, such as Figure 1-10 As shown, the production process and device of the galvanized sheet of the washing machine include: a base plate 1, on which a passivation tank 2 for passivating the galvanized sheet is provided; a drying box 3 arranged on one side of the passivation tank 2, for drying the passivated galvanized sheet; a transfer mechanism, arranged between the passivation tank 2 and the drying box 3, the transfer mechanism including a lifting assembly and a rotating assembly, for automatically transferring the galvanized sheet from the passivation tank 2 to the drying box 3; a drying mechanism, the drying mechanism is arranged on the drying box 3, for supplying hot air into the drying box 3; an air supply mechanism, the air supply mechanism is arranged on the passivation tank 2, for supplying air therein.

[0020] In this embodiment, on the base plate 1, the galvanized sheet is first placed in the passivation tank 2 for passivation treatment; after the passivation is completed, the transfer mechanism is started, and its lifting component first operates to lift the galvanized sheet from the passivation tank 2, and then the rotating component rotates to automatically transfer the galvanized sheet to one side of the drying box 3, and then the lifting component descends to send the galvanized sheet into the drying box 3. The drying mechanism starts to work, and hot air is supplied to the drying box 3 to dry the galvanized sheet; the transfer mechanism realizes the automatic transfer of the galvanized sheet from the passivation to the drying link, without manual handling, which greatly saves manpower investment and reduces labor costs. The automatic transfer process is efficient and rapid, which reduces the time and energy consumed by handling, and greatly improves the overall production efficiency. The air supply mechanism and the drying mechanism provide good working conditions for the passivation and drying links respectively, which helps to improve product quality; by reasonably setting up various components and mechanisms, the problems of poor equipment connection and low production efficiency in the existing production process are solved, while reducing costs, the production efficiency and product quality are improved, which has significant advantages and practical value.

[0021] In a further preferred embodiment of the present invention, the lifting assembly includes: an electric hydraulic rod 4 fixedly mounted on the base plate 1, the top end of the output rod of the electric hydraulic rod 4 is equipped with a mounting seat 5; a rotatable mounting box 6 is arranged on the mounting seat 5, and the mounting box 6 is symmetrically equipped with a first rotating rod 8 through a bearing; a placement rack 7 fixedly mounted on the corresponding bottom end of the first rotating rod 8, and the placement rack 7 can enter and exit the passivation tank 2 and the drying box 3, and is used for placing the galvanized sheet to be passivated.

[0022] In this embodiment, the electric hydraulic rod 4 fixedly mounted on the base plate 1 starts to work, and its output rod extends upward, driving the mounting seat 5 assembled at the top to rise. The rotatable and adjustable mounting box 6 on the mounting seat 5 rises accordingly, and at this time, the first rotating rod 8 symmetrically assembled on the mounting box 6 through the bearing also rises together. The placement rack 7 fixed at the bottom end of the first rotating rod 8 gradually rises from the position of the base plate 1 with the rising action and enters the passivation tank 2. The galvanized sheet is placed on the placement rack 7 for passivation treatment. After completion, the electric hydraulic rod 4 continues to work and lifts the placement rack 7 from the passivation tank 2. Subsequently, the mounting box 6 is rotated and adjusted, driving the first rotating rod 8 and the placement rack 7 to rotate to one side of the drying box 3, the output rod of the electric hydraulic rod 4 descends, and the placement rack 7 enters the drying box 3, completing the transfer preparation of the galvanized sheet from the passivation tank 2 to the drying box 3; the electric hydraulic rod 4 provides a stable and controllable lifting power, which can accurately control the height of the placement rack 7 to ensure that the galvanized sheet can smoothly enter and exit the passivation tank 2 and the drying box 3. The installation box 6 can be rotated and adjusted, and cooperates with the first rotating rod 8, so that the placement rack 7 can flexibly change direction, which is convenient for transfer from the passivation tank 2 to the drying box 3, greatly improving the flexibility and accuracy of the transfer process. The placement rack 7 is specially used to place the galvanized sheet, which ensures the stability of the galvanized sheet during the transfer process, avoids the galvanized sheet from shaking, falling, etc. during the transportation process, and helps to improve product quality and the safety of the production process; through the coordinated work of various components, in the entire washing machine galvanized sheet production process, the galvanized sheet is efficiently, stably and safely transferred between the passivation and drying links, further improving the overall production efficiency, reducing the potential risks in the production process, and playing a positive role in improving product quality and optimizing the production process.

[0023] In a further preferred embodiment of the present invention, the rotating assembly includes: a second rotating rod 14 assembled on the mounting seat 5 through a bearing seat, and the top end of the second rotating rod 14 extends into the mounting box 6; a motor 10 fixedly mounted in the mounting box 6, and a spline cylinder 15 is fixedly mounted on the output shaft of the motor 10; a spline rod 16 fixedly mounted on the top end of the second rotating rod 14, and the spline rod 16 can be inserted into the spline cylinder 15; a mounting cylinder 17 symmetrically fixedly mounted at the bottom of the mounting box 6, and a slide plate 18 is slidably mounted in the mounting cylinder 17, and the bottom end of the slide plate 18 is inlaid with a first ball 19, and the first ball 19 is in contact with the mounting seat 5.

[0024] In this embodiment, when the installation box 6 needs to be rotated to transfer the placement rack 7, the motor 10 is started. The output shaft of the motor 10 drives the spline cylinder 15 to rotate. Since the spline rod 16 is fixedly mounted on the top of the second rotating rod 14 and can be inserted into the spline cylinder 15, the rotation of the spline cylinder 15 drives the spline rod 16 and the second rotating rod 14 to rotate synchronously. The second rotating rod 14 is assembled on the installation seat 5 through the bearing seat, so the rotation of the second rotating rod 14 drives the installation box 6 to rotate around the axis of the second rotating rod 14. During the rotation of the installation box 6, the slide plate 18 slides in the installation cylinder 17 symmetrically fixed at the bottom of the installation box 6, and the first ball 19 embedded at the bottom of the slide plate 18 is always in contact with the mounting seat 5 and rolls, which assists the installation box 6 to rotate smoothly, thereby driving the first rotating rod 8 and the placement rack 7 on the installation box 6 to rotate to the side of the drying box 3 to complete the rotation transfer action; the cooperation between the motor 10 and the spline cylinder 15 and the spline rod 16 can accurately and efficiently transmit power, so that the installation box 6 can rotate quickly and stably, ensuring that the placement rack 7 can be accurately transferred from the passivation tank 2 to the corresponding position of the drying box 3, greatly improving the transfer efficiency. The design of the installation cylinder 17, the slide plate 18 and the first ball 19 plays a good supporting and guiding role when the installation box 6 rotates, reducing the friction during the rotation of the installation box 6, ensuring the stability of the rotation process, reducing equipment wear, and extending the service life of the equipment. The design of this rotating component makes the transfer mechanism more coordinated during the overall operation process, and improves the fluency and stability of the entire production process.

[0025] In a further preferred embodiment of the present invention, the drying mechanism includes: a heating box 23 fixedly mounted on one side of the drying box 3, wherein a plurality of electric heating tubes 26 are arranged in the heating box 23; a third rotating rod 24 assembled in the heating box 23 through a bearing, wherein a first fan blade 25 is fixedly mounted on the third rotating rod 24; and an annular tube 28 fixedly mounted in the drying box 3 and capable of being raised and lowered, wherein an air inlet end of the annular tube 28 is connected to the heating box 23 through a telescopic tube 27.

[0026] In this embodiment, when it is necessary to dry the galvanized sheet entering the drying box 3, the multiple electric heating tubes 26 in the heating box 23 start to work and heat the air in the heating box 23. At the same time, the third rotating rod 24 rotates through the bearing in the heating box 23, and the first fan blade 25 fixedly installed thereon rotates accordingly, blowing the heated air to the telescopic tube 27. The heated air enters the annular tube 28 through the telescopic tube 27. Since the annular tube 28 is fixedly installed in the drying box 3 and can be raised and lowered, the height can be adjusted according to the actual position of the galvanized sheet to ensure that the hot air acts evenly on the galvanized sheet, thereby achieving the drying treatment of the galvanized sheet; the multiple electric heating tubes 26 can heat the air quickly and efficiently, providing a sufficient heat source for drying. The cooperation of the first fan blade 25 and the third rotating rod 24 enables the hot air to be quickly and continuously transported to the drying box 3, speeding up the drying process and improving the drying efficiency. The lifting design of the ring tube 28 can flexibly adapt to galvanized sheets of different specifications and different placement heights, ensure that the hot air evenly covers the surface of the galvanized sheet, improve the uniformity of the drying effect, avoid the situation of insufficient or excessive local drying, and thus improve the product quality. The telescopic tube 27 maintains a stable connection state during the lifting process of the ring tube 28 to ensure that the hot air transmission is not affected; the drying mechanism, through the coordinated operation of the heating box 23, the electric heating tube 26, the third rotating rod 24, the first fan blade 25, the ring tube 28 and the telescopic tube 27, provides an efficient, uniform and adjustable drying method for the galvanized sheet in the production process of the washing machine galvanized sheet, further optimizes the production process, plays a key role in improving production efficiency and product quality, and helps to meet the needs of galvanized sheet drying in different production scenarios.

[0027] In a further preferred embodiment of the present invention, an electric telescopic rod 21 is mounted on the placement rack 7 via a bracket 20, and a pressure plate 22 for limiting the position of the galvanized sheet is fixedly mounted on the output rod of the electric telescopic rod 21.

[0028] In this embodiment, when the galvanized sheet needs to be placed on the placement rack 7 for passivation or drying treatment, the galvanized sheet is first placed on the surface of the placement rack 7. Subsequently, the electric telescopic rod 21 assembled on the placement rack 7 through the bracket 20 is started, and its output rod extends, driving the pressing plate 22 fixedly installed on the output rod to move downward. The pressing plate 22 gradually approaches the galvanized sheet until the galvanized sheet is pressed tightly on the placement rack 7 to achieve the limit of the galvanized sheet. During the entire transfer and processing process, the electric telescopic rod 21 maintains support for the pressing plate 22 to ensure that the galvanized sheet is stably fixed on the placement rack 7. When the processing is completed and the galvanized sheet needs to be removed, the output rod of the electric telescopic rod 21 retracts, driving the pressing plate 22 to move upward, releasing the limit of the galvanized sheet, and the galvanized sheet can be removed smoothly; the cooperation between the electric telescopic rod 21 and the pressing plate 22 can effectively limit the galvanized sheet, prevent the galvanized sheet from shaking and displacing during the operation of the transfer mechanism, and affect the processing effect, greatly improve the stability of the galvanized sheet on the placement rack 7, and help improve product quality. This design can flexibly adapt to galvanized plates of different thicknesses by adjusting the extension length of the output rod of the electric telescopic rod 21, thereby enhancing the applicability of the placement rack 7 to galvanized plates of various specifications. In addition, this automated limiting method is more convenient and efficient than manual fixing, reduces manual operation links, and further improves overall production efficiency.

[0029] In a further preferred embodiment of the present invention, a reciprocating screw 29 is assembled in the drying box 3 through a bearing seat, a sleeve block 30 is threadedly sleeved on the reciprocating screw 29, one end of the sleeve block 30 is fixedly connected to the ring tube 28, and a guide rod 31 is fixedly installed in the drying box 3, a connecting block is slidably sleeved on the guide rod 31, and one end of the connecting block is fixedly connected to the ring tube 28.

[0030] In this embodiment, when the drying box 3 starts to work, the reciprocating screw 29 starts to rotate under the support of the bearing seat. Since the sleeve block 30 is threadedly sleeved on the reciprocating screw 29, the rotation of the reciprocating screw 29 will drive the sleeve block 30 to make reciprocating linear motion along the screw. One end of the sleeve block 30 is fixedly connected to the annular tube 28, so the reciprocating motion of the sleeve block 30 drives the annular tube 28 to reciprocate synchronously. At the same time, the guide rod 31 is fixedly installed in the drying box 3, and the connecting block is slidably sleeved on the guide rod 31, and one end of the connecting block is also fixedly connected to the annular tube 28. The combination of the guide rod 31 and the connecting block plays a guiding role, ensuring that the ring tube 28 remains stable when it reciprocates with the sleeve block 30, and will not deviate or shake, so that the ring tube 28 can reciprocate regularly in the drying box 3, so that the hot air can act evenly on different positions of the galvanized sheet; the design of the reciprocating screw rod 29 and the sleeve block 30 realizes the reciprocating movement of the ring tube 28, so that the hot air can blow the surface of the galvanized sheet more comprehensively and evenly, avoiding the situation of insufficient or excessive local drying, greatly improving the uniformity of drying, and helping to improve product quality. The cooperation of the guide rod 31 and the connecting block ensures the stability of the movement of the ring tube 28, reduces wear during the operation of the equipment, and extends the service life of the equipment. This adjustable movement mode of the ring tube 28 can flexibly adjust the movement range and frequency of the ring tube 28 according to the size, shape and drying process requirements of different galvanized sheets, enhances the adaptability of the drying box 3 to diversified production needs, and improves the versatility and practicality of the equipment.

[0031] In a further preferred embodiment of the present invention, the air supply mechanism includes: a mounting shell 32 fixedly mounted on the passivation tank 2, a fourth rotating rod 33 being assembled in the mounting shell 32 through a bearing, a second fan blade 34 being fixedly mounted on the fourth rotating rod 33; an air supply pipe 35 fixedly connected to the mounting shell 32, an air outlet end of the air supply pipe 35 extending into the passivation tank 2; an air inlet pipe 46 fixedly connected to the mounting shell 32 and the heating box 23, respectively, and a dustproof mesh cover being provided on the air inlet pipe 46.

[0032] In this embodiment, when the air supply mechanism is started, the fourth rotating rod 33 starts to rotate through the bearing in the mounting shell 32, and the second fan blade 34 fixedly mounted on the fourth rotating rod 33 rotates synchronously therewith. The rotating second fan blade 34 draws air into the mounting shell 32, and the air is transported from its outlet end to the passivation tank 2 through the air supply pipe 35, providing the necessary air environment for the passivation treatment of the galvanized sheet in the passivation tank 2. At the same time, the mounting shell 32 is fixedly connected to the heating box 23 through the air inlet pipe 46, and air can enter the heating box 23 through the air inlet pipe 46. The dustproof mesh cover set on the air inlet pipe 46 can filter dust and other impurities in the air, ensure that the air entering the heating box 23 is clean, prevent impurities from affecting the normal operation of the drying mechanism and causing pollution to the galvanized sheet; the cooperation between the second fan blade 34 and the fourth rotating rod 33 can continuously and efficiently transport air into the passivation tank 2, meet the air demand of the passivation reaction, help to accelerate the passivation reaction process, and improve production efficiency. The air inlet pipe 46 connects the mounting shell 32 with the heating box 23, realizing the rational use of air, so that the air supply mechanism can supply air to the passivation tank 2 while also providing air to the heating box 23, reducing the number of additional air supply devices and reducing costs. The setting of the dustproof mesh effectively filters the air entering the heating box 23, protects the electric heating pipe 26 and other components inside the drying mechanism, reduces equipment failures caused by impurities, prolongs the service life of the equipment, and at the same time ensures the cleanliness of the galvanized sheet during the drying process, thereby improving product quality.

[0033] In a further preferred embodiment of the present invention, a drain pipe for discharging accumulated liquid is fixedly connected to the drying box 3, and a valve is provided on the drain pipe.

[0034] In this embodiment, during the drying process of the passivated galvanized sheet in the drying box 3, since there may be passivation liquid remaining on the surface of the galvanized sheet, these liquids may evaporate under heat to form water vapor during drying, and part of the water vapor will re-condense into accumulated liquid when it encounters cold in the drying box 3. The drainage pipe fixedly connected to the drying box 3 is used to discharge these accumulated liquids. When the accumulated liquids accumulate to a certain extent, the valve set on the drainage pipe is opened, and the accumulated liquids will be discharged from the drying box 3 through the drainage pipe, thereby ensuring that the internal environment of the drying box 3 is suitable and does not affect the continuous drying work; the setting of the drainage pipe and the valve can timely remove the accumulated liquid in the drying box 3, avoid the long-term accumulation of accumulated liquid to cause corrosion to the internal structure and equipment of the drying box 3, and extend the service life of the drying box 3. At the same time, it effectively prevents the accumulated liquid from interfering with the drying process, such as preventing the accumulated liquid from splashing onto the galvanized sheet to affect the drying effect or cause secondary pollution of the galvanized sheet, which helps to improve product quality.

[0035] In a further preferred embodiment of the present invention, the passivation tank 2 is fixedly connected to a fluid exchange pipe, the fluid exchange pipe is provided with a solenoid valve, and support columns 45 are symmetrically fixedly installed on the placement rack 7, and a second ball is embedded on the bottom end of the support column 45.

[0036] In this embodiment, during the production process of the galvanized sheet of the washing machine, as the passivation treatment continues, the passivation liquid in the passivation tank 2 will gradually become ineffective or contaminated. At this time, it is necessary to replace the liquid in the passivation tank 2. By fixing the liquid exchange pipe connected to the passivation tank 2, when the liquid needs to be replaced, the solenoid valve provided on the liquid exchange pipe is opened, and the old passivation liquid will flow out of the passivation tank 2 through the liquid exchange pipe. After the drainage is completed, a new passivation liquid can be injected through the liquid exchange pipe to achieve the renewal of the liquid in the passivation tank 2. After the placement rack 7 is lowered and positioned, the balls embedded at the bottom of the support column 45 play a role, and the corresponding balls will contact the annular grooves at the top of the passivation tank 2 and the drying box 3, which can play a supporting role and does not affect the rotation of the placement rack 7. The old liquid can be quickly and efficiently discharged and new liquid can be injected, reducing the time and labor cost required for liquid replacement. At the same time, regular replacement of the passivation liquid helps to maintain the effect of the passivation treatment, ensure the passivation quality of the galvanized sheet, and thus improve product quality.

[0037] 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 transmission mechanism is provided on the installation box 6, and the transmission mechanism includes: two first transmission rods 9 symmetrically assembled in the installation box 6 through a bearing seat, and one end of each of the two first transmission rods 9 is fixedly mounted with a second bevel gear 12; a first bevel gear 11 fixedly mounted on the output shaft of the motor 10, and the first bevel gear 11 is meshed with the second bevel gear 12; a third bevel gear 13 fixedly mounted on the first transmission rod 9 and the first rotating rod 8 and meshed with each other; a fourth bevel gear 36 fixedly mounted on the fourth rotating rod 33; a second transmission rod 38 assembled between the drying box 3 and the heating box 23 through a bearing seat, and the second transmission rod 38 is meshed with the third rotating rod 24 A first pulley 40 is fixedly installed on each of the two first pulleys 40, and a same first transmission belt 41 is sleeved on the two first pulleys 40; a second pulley 42 is fixedly installed on the third rotating rod 24 and the reciprocating screw rod 29, respectively, and a same second transmission belt 43 is sleeved on the two second pulleys 42; a protective shell 44 is fixedly installed on the drying box 3 and the heating box 23, and the protective shell 44 is used to shield the first pulley 40 and the second pulley 42; a sixth bevel tooth 39 is fixedly installed on the second transmission rod 38; and fifth bevel teeth 37 are fixedly installed on the other ends of the two first transmission rods 9, respectively, and the two fifth bevel teeth 37 can mesh with the corresponding sixth bevel teeth 39 and the fourth bevel teeth 36 at any time.

[0038] In this embodiment, when the motor 10 is started, its output shaft drives the first bevel gear 11 to rotate. Since the first bevel gear 11 is meshed with the second bevel gear 12, the rotation of the first bevel gear 11 drives the two first transmission rods 9 to rotate synchronously in the installation box 6 through the bearing seat.
