Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate production, in particular to a metal plate spraying device for mechanical manufacturing and a spraying process. BACKGROUND

[0002] Metal plate spraying devices are widely used in the field of mechanical manufacturing to apply protective or functional coatings to metal plates such as steel and aluminum plates. They are commonly used in industries such as excavators, automobiles, and construction machinery. Coatings not only improve the corrosion resistance, wear resistance, and aesthetic properties of metal plates, but also meet specific functional requirements (such as thermal insulation or electrical conductivity). In mechanical manufacturing, metal plates are usually large in size (e.g., 0.5-5 meters long) and can be up to 10-60 millimeters thick.

[0003] In existing metal plate spraying technology, metal plates are often hung by iron wires, and then sprayed by manual operation of a spray gun. Although this method is simple and low-cost, it has significant technical defects. First, manual spraying is inefficient, relying on the experience and skills of operators, and the spraying speed is slow and inconsistent. For example, spraying a single large plate (such as a 1 square meter steel plate) may take several minutes, and in batch production, manual operation cannot meet the high-efficiency and continuous production requirements. Second, the iron wire hanging method easily leaves hanging point defects on the plate surface. The contact area between the iron wire and the plate (usually 1-2 square millimeters) blocks the paint spray, causing the local coating on the plate surface to be missing or uneven, forming "hanging points" or "shadow zones". These hanging points not only affect the appearance of the coating, but also may weaken the corrosion resistance, increasing the cost of subsequent repairs. SUMMARY

Detailed Implementation

[0049] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

However, it should be noted that the conveyor belt of the suspended chain conveyor 1 is equipped with multiple first lifting fixtures 11. The metal plate 100 is suspended from the raw material storage mechanism 2, the suspended chain conveyor 1, and the finished product storage mechanism 5 via the hoisting mechanism 3. When the metal plate 100 moves, the corresponding hoisting mechanism 3 will also move synchronously. The raw material storage mechanism 2 is located on one side of the head end of the suspended chain conveyor 1 and is used to store the metal plate 100 to be sprayed.

[0052] The lifting mechanism 3 is the core component in the embodiment, which can replace the mounting surface of the metal plate 100, and then respectively stagger the one side of the spraying mechanism 4 spraying operation, to avoid leaving a hanging point on the outer surface of the metal plate 100, and improve the spraying quality of the metal plate 100. The lifting mechanism 3 comprises a moving assembly 31, the moving assembly 31 cooperates with the first lifting tool 11 or the moving assembly 31 cooperates with the second lifting tool 21, to realize the displacement of the lifting mechanism 3, to move the metal plate 100 to the suspended chain conveyor 1 or the finished product storage mechanism 5, to realize automatic operation.

[0053] The moving assembly 31 comprises a connecting seat 311, a first motor 312 is fixed in the connecting seat 311, a support shell 313 is fixed on the upper side of the connecting seat 311, a ball (not shown in the figure) is rotatably installed on the lower side of the support shell 313, the ball is in contact with the upper surface of the lower side transverse part of the elongated frame 211, which can reduce the friction, the support shell 313 is rotatably installed with a driving gear 314 connected with the output end of the first motor 312, the support shell 313 is rotatably installed with two driven gears 315 meshed with the driving gear 314, and the two driven gears 315 are both meshed with the straight rack 213.

[0054] When the first lifting tool 11 and the second lifting tool 21 are connected, the first motor 312 is operated to drive the whole lifting mechanism 3 to displace, to realize the movement of the lifting mechanism 3 from the raw material storage mechanism 2 to the suspended chain conveyor 1 or the movement of the lifting mechanism 3 from the suspended chain conveyor 1 to the finished product storage mechanism 5; the moving assembly 31 is provided with an electric control box 32, which has an electric power storage and a controller inside, to realize the power supply and the control unit for the lifting mechanism 3; a side wheel 316 is installed on the side of the support shell 313 away from the driven gear 315, the side wheel 316 is in contact with the inner side wall of the elongated frame 211, and the side wheel 316 is used to ensure the meshing degree between the driven gear 315 and the straight rack 213.

[0055] The lower end of the moving assembly 31 is connected with two hanging assemblies 34 through a cross bar frame. In order to make the hoisting mechanism 3 adapt to the hanging of metal plates 100 with different widths, the cross bar frame comprises a cross bar 331 fixed to the lower end of the moving assembly 31, and the two sides of the cross bar 331 are slidably sleeved with sliding frames 332. The two hanging assemblies 34 are respectively fixed to the two sliding frames 332. Screws 333 are threadedly connected to the sliding frames 332, so as to lock or release the sliding frames 332. A scale can be marked on the cross bar 331, so as to facilitate the operator to accurately adjust the position of the hanging assembly 34.

[0056] The hanging assembly 34 comprises a mounting seat 341 mounted on the sliding frame 332 of the cross bar frame. The mounting seat 341 is provided with a power assembly and two arc-shaped strips 345 slidably arranged on the mounting seat 341. The sliding direction of the arc-shaped strips 345 is along the arc direction, that is, the arc-shaped strips 345 essentially rotate around the center. The arc-shaped strips 345 slide through the corresponding positions of the mounting seat 341. The two arc-shaped strips 345 are respectively located on the two sides of the mounting seat 341. The lower end of one of the arc-shaped strips 345 is slidably mounted with a first supporting rod 371, and the first supporting rod 371 extends to the outside of the corresponding arc-shaped strip 345. The inner side of the first supporting rod 371 is provided with a spring 372. Specifically, an installation inner hole is formed at the lower end of the corresponding arc-shaped strip 345, and the spring 372 and the first supporting rod 371 are sequentially arranged from inside to outside in the installation inner hole. The size of the first supporting rod 371 in the installation inner hole has a certain length, so that it can withstand the weight of the metal plate 100 without tilting. The lower end of the other arc-shaped strip 345 is fixed with a second supporting rod 373.

[0057] It should be noted that the second supporting rod 373 and the first supporting rod 371 are located on an arc line with the center of the arc-shaped strip 345, that is, when the two arc-shaped strips 345 slide downward, the first supporting rod 371 and the second supporting rod 373 will finally touch and dock. The diameter of the through hole of the metal plate 100 is greater than the outer diameter of the first supporting rod 371, and the outer diameter of the first supporting rod 371 is greater than the outer diameter of the second supporting rod 373. Since the arc-shaped strip 345 slides in the arc direction, when the metal plate 100 is hung on the first supporting rod 371 or the second supporting rod 373, the first supporting rod 371 or the second supporting rod 373 is subjected to the vertical downward force of the weight of the metal plate 100. Therefore, the arc-shaped strip 345 and the mounting seat 341 can withstand the weight of the metal plate 100 without self-displacement of the arc-shaped strip 345. In use, the metal plate 100 is first hung on the first supporting rod 371.

[0062] The pushing assembly includes a reset rod 353 installed on the upper end of the arc-shaped strip 345 through a torsion spring seat and a guide fixed to the side wall of the mounting seat 341, and the guide is arranged at an angle with the arc-shaped strip 345, one end of the guide extends to the axial inner side of the arc-shaped strip 345 (that is, axially overlaps the arc-shaped strip 345), and the other end extends to the axial outer side of the arc-shaped strip 345 (that is, does not axially overlap the arc-shaped strip 345); the guide includes a guide rod 351 fixed to the bracket and a one-way rotating rod 352 installed on the inner end of the guide rod 351 through a torsion spring (not shown in the figure), and the inner end of the one-way rotating rod 352 extends to the axial inner side of the arc-shaped strip 345, and the one-way rotating rod 352 cannot be flipped to one side of the arc-shaped strip 345, but can be flipped to the side away from the arc-shaped strip 345.

[0067] Step one, preparation: the plurality of metal plates 100 to be sprayed are hung on the raw material storage mechanism 2 in turn through the lifting mechanism 3, specifically: the arc-shaped strip 345 of the initial first hook piece is in a downward extending state, and the metal plate 100 is hung on the first support rod 371 of the first hook piece; at the same time, the position of the lifting mechanism 3 can be adjusted through the moving assembly 31, so that the metal plates 100 are densely arranged, thereby allowing more metal plates 100 to be placed on one raw material storage mechanism 2, and then the raw material storage mechanism 2 and the finished product storage mechanism 5 are moved to the corresponding positions for subsequent use;

[0068] Step two, move the metal plate 100: run the suspension chain conveyor 1 so that the corresponding first lifting tool 11 is connected with the second lifting tool 21 of the raw material storage mechanism 2, and run the moving assembly 31 to move the metal plate 100 hung with the lifting mechanism 3 to the first lifting tool 11 of the suspension chain conveyor 1, and then transmit the metal plate 100 through the suspension chain conveyor 1, and the metal plate 100 will be transmitted to one side of the spraying mechanism 4;

[0069] The specific process of moving the lifting mechanism 3 through the moving assembly 31 is as follows:

[0070] Running the first motor 312 will drive the driving gear 314 to rotate, further driving the two driven gears 315 to rotate. The driven gears 315 cooperate with the straight teeth 213 of the raw material storage mechanism 2 to drive the support shell 313 to gradually move into the first lifting tool 11, until the driven gears 315 mesh with the straight teeth 213 of the first lifting tool 11, and finally the support shell 313 is moved into the first lifting tool 11, and then the suspension chain conveyor 1 drives the lifting mechanism 3 and the metal plate 100 to move;

[0072] Step four, change the mounting surface: drive the power assembly to drive the arc-shaped strip 345 fixed with the second support rod 373 to flip downward until the second support rod 373 pushes the first support rod 371 to retract, i.e. the weight of the metal plate 100 is borne by the second support rod 373, and the mounting of the other side is completed;

[0073] The specific process of step four is as follows:

[0074] At this time, the movable gear 344 in the second hook piece is circumferentially coupled with the shaft 343 through the coupling piece 36, and the movable gear 344 in the first hook piece is in a rotating connection state with the shaft 343;

[0075] When the second motor 342 is running, the rotating shaft 343 can drive the movable gear 344 of the second hook piece to rotate, and then the arc-shaped strip 345 in the second hook piece and the second support rod 373 move downward along an arc line until the first support rod 371 is driven to retract by the second support rod 373, and the metal plate 100 will be supported by the second support rod 373, and the second support rod 373 replaces the first support rod 371 to bear the weight of the metal plate 100;

[0076] During the above-mentioned action process, the reset rod 353 in the second hook piece will be in contact with the outer side of the corresponding one-way rotating rod 352, and will be gradually turned upward due to the guidance of the one-way rotating rod 352, so as to store force for the torsional spring, until the reset rod 353 is out of contact with the guide rod 351, the reset rod 353 will rebound due to the force of the torsional spring (at this time, the straight grooves 3442 of the two movable gears 344 will be corresponding), and the end of the reset rod 353 will hit the corresponding outer block 362, thereby giving the coupling piece 36 a moving force, after the coupling piece 36 moves, the movable gear 344 in the first hook piece and the rotating shaft 343 are circumferentially coupled through the coupling piece 36, and the movable gear 344 in the second hook piece and the rotating shaft 343 are in a rotating connection state, completing the switching of transmission (at this time, it needs to be noted that the reset rod 353 should avoid contacting with the outer block 362 to prevent the outer block 362 from interfering with the reset rod 353 when rotating);

[0077] Subsequently, further running the second motor 342, the rotating shaft 343 will drive the movable gear 344 of the first hook piece to rotate, and then drive the arc-shaped strip 345 of the first hook piece and the second support rod 373 to retract upward, and during this process, the reset rod 353 of the first hook piece will be in contact with the inner side of the one-way rotating rod 352, and due to the force of the torsional spring, the one-way rotating rod 352 will be turned outward, so that the reset rod 353 passes smoothly, and the arc-shaped strip 345 of the first hook piece retracts upward to avoid interfering with the spraying of the metal plate 100;

[0078] Step five, second spraying: starting the second spraying mechanism 4 to perform spraying work on the other side of the metal plate 100;

[0079] Step six, moving to the finished product storage mechanism 5: when the metal plate 100 completing the spraying work moves to the corresponding finished product storage mechanism 5, the metal plate 100 mounted with the hoisting mechanism 3 is moved to the second lifting tool 21 of the finished product storage mechanism 5 by running the moving assembly 31;

[0080] The specific process of moving the hoisting mechanism 3 by the moving assembly 31 is as follows:

[0081] When the first motor 312 is operated, the driving gear 314 is rotated, and the two driven gears 315 are further rotated. The driven gears 315 are matched with the straight rack 213 of the first lifting tool 11, and the support shell 313 is driven to move gradually into the second lifting tool 21 of the finished product storage mechanism 5 until the driven gears 315 are engaged with the straight rack 213 of the finished product storage mechanism 5, and finally the support shell 313 is moved into the second lifting tool 21 of the finished product storage mechanism 5.

[0082] After the spraying work of the metal plate 100 is completed by the spraying device in the embodiment, a process of spraying the through hole of the metal plate 100 is subsequently performed. Since the through hole on the metal plate 100 is used for inserting a bolt, the appearance of the metal plate 100 is not affected.

[0083] The above description is merely preferred embodiments of the present application, merely illustrative, but not restrictive. It is understood by those skilled in the art that many changes, modifications, and even equivalents can be made within the spirit and scope of the present application defined by the claims, and all shall fall within the protection scope of the present application.
