[0049] It should be noted that the linkage plate 525 can slide longitudinally inside the L-shaped card plate 527. During the use of the powder coating machine, the L-shaped card plate 527 does not limit the longitudinal movement of the linkage plate 525. The role of the L-shaped card plate 527 is to make the linkage plate 525 slide against the surface of the rectangular plate 516.

[0051] It should be noted that: the first one-way valve 42 and the second one-way valve 415 are existing technologies. Under the action of the first one-way valve 42, the paint can pass through the interior of the first mounting hole 43 and flow into the side of the partition 41 away from the piston plate 44, and the flow direction of the paint is irreversible. Under the action of the second one-way valve 415, the paint can pass through the interior of the discharge pipe 414 and flow into the interior of the powder cylinder 1, and the flow direction of the paint is irreversible.

[0052] Working principle: When the powder coating machine is in use, the electric hydraulic push rod 47 and the air pump 51 are connected to the external power supply, and the paint is transported to the inside of the transfer storage box 413 through the external conveying mechanism. The operation controller starts the electric hydraulic push rod 47 and the air pump 51. The operation of the electric hydraulic push rod 47 and its telescopic rod begin to reciprocate. The operation of the air pump 51 causes the external gas to flow into the auxiliary storage box 48 along the inside of the connecting air pipe 52. When the rectangular counterweight block 411 and the first blocking plate 412 are attached, as the gas continues to flow along the inside of the connecting air pipe 52, the gas flows into the auxiliary storage box 48. When the gas flows into the auxiliary storage box 48, the air pressure in the space formed by the auxiliary storage box 48 and the rectangular counterweight 411 increases, and the force exerted by the air pressure on the rubber sealing ball 57 increases continuously. When the air pressure in the auxiliary storage box 48 pushes the rubber sealing ball 57 to move, the first spring 511 is compressed. At this time, the gas in the auxiliary storage box 48 can flow out along the gap between the rubber sealing ball 57 and the blocking disc 56, and the force exerted by the air pressure in the auxiliary storage box 48 on the rectangular counterweight 411 is less fluctuating.

[0053] When the telescopic rod inside the electric hydraulic push rod 47 begins to retract, the telescopic rod of the electric hydraulic push rod 47 drives the second connecting rod 46 to move in the direction close to the powder cylinder 1. The movement of the second connecting rod 46 drives the piston plate 44 to slide inside the powder cylinder 1 through the first connecting rod 45. In the process of the piston plate 44 moving toward the partition 41, the paint between the piston plate 44 and the partition 41 flows through the inside of the first mounting hole 43 to the side of the partition 41 away from the piston plate 44. As the paint continues to flow away from the side of the partition 41 away from the piston plate 44, the paint on the side of the partition 41 away from the piston plate 44 is under pressure. Due to the continuous sliding of the welding rod inside the guide tube 2 and the powder coating mold 3, the powder coating process of the welding rod is realized. When the telescopic rod inside the electric hydraulic push rod 47 begins to extend, the electric The telescopic rod of the electric hydraulic push rod 47 drives the second connecting rod 46 to move in the direction away from the powder cylinder 1. The movement of the second connecting rod 46 drives the piston plate 44 to slide inside the powder cylinder 1 through the first connecting rod 45, so as to extract the paint stored in the transfer storage box 413, so that the paint inside the transfer storage box 413 flows along the inside of the discharge pipe 414 to between the partition 41 and the piston plate 44, and then in the process of the electric hydraulic push rod 47 driving the piston plate 44 to reciprocate, the paint between the partition 41 and the piston plate 44 flows to the side of the partition 41 away from the piston plate 44, thereby increasing the pressure of the paint there, achieving the effect of powder coating on the welding rod, and making the paint inside the transfer storage box 413 flow between the partition 41 and the piston plate 44, so as to ensure the supply of paint;

[0054] When the telescopic rod inside the electric hydraulic push rod 47 begins to retract, as the paint on the side of the partition 41 away from the piston plate 44 continues to flow in, the paint on the side of the partition 41 away from the piston plate 44 is under pressure. Under the action of the pressure, a part of the paint is coated inside the machine head 8, thereby alleviating the pressure of the paint continuously flowing into the inside of the machine head 8, and a part of the paint flows into the inside of the auxiliary storage box 48 under the action of the pressure of the paint. Under the action of the paint pressure, the paint inside the auxiliary storage box 48 pushes the rectangular counterweight block 411 to slide inside the auxiliary storage box 48, thereby making the auxiliary storage The paint inside the storage box 48 is continuously increasing. The effect achieved by this process is that when the piston plate 44 pushes the paint between the partition plate 41 and the piston plate 44 to flow to the side of the partition plate 41 away from the piston plate 44, the paint is applied to the welding rod and flows into the auxiliary storage box 48 to store the paint passing through the partition plate 41. In this process, the welding rod slides at a uniform speed inside the guide tube 2 and the powder coating mold 3, and the telescopic rod of the electric hydraulic push rod 47 drives the piston plate 44 to move at a uniform speed, thereby making the pressure fluctuation of the paint inside the machine head 8 smaller, thereby ensuring the effect of powder coating on the welding rod;

[0055] During this process, the movement of the second connecting rod 46 drives the linkage plate 525 to slide inside the L-shaped card plate 527, and the movement of the linkage plate 525 drives the connecting optical axis 526 to move under the dividing plate 517. Under the action of the elastic potential energy of the first spring 511, the connecting optical axis 526 fits the inner wall of the square slide groove 518 and moves under the dividing plate 517. As the second connecting rod 46 continues to move, the connecting optical axis 526 continues to move. When the connecting optical axis 526 and the inclined section 524 opened at the end of the plug-in board 521 fit and slide, the connecting optical axis 526 applies a force to the plug-in board 521 to make the plug-in board 521 slide inside the side through groove 519. At this time, the second spring 523 is in a state of continuous compression. When the plug-in board 521 moves a distance that can make the connecting optical axis 526 When the connecting optical axis 526 slides through the gap between the plug-in board 521 and the baffle plate 517, as the connecting optical axis 526 slides in contact with the inclined cut surface 524, under the action of the inclined surface, the connecting optical axis 526 moves to the top of the plug-in board 521, and under the action of the elastic potential energy of the second spring 523, the plug-in board 521 slides along the inside of the side through groove 519 and slides to fit with the end of the baffle plate 517. In this process, since the height of the linkage plate 525 and the connecting optical axis 526 remains unchanged, when the connecting optical axis 526 moves to the top of the plug-in board 521, the rectangular plate 516 moves downward, and at this time, the telescopic rod of the electric hydraulic push rod 47 retracts to the extreme, so that the paint between the piston plate 44 and the partition plate 41 cannot continue to flow along the inside of the partition plate 41;

[0056] During this process, the rectangular plate 516 moves downward and drives the first longitudinal slide bar 514 to move downward through the cross bar 515. The movement of the first longitudinal slide bar 514 drives the upper connecting plate 512 to move downward through the threaded rod 62. The upper connecting plate 512 shortens the distance between the lower connecting plate 59 and the upper connecting plate 512 during the movement, thereby causing the first spring 511 to continue to be compressed. As the first spring 511 is compressed, the force applied to the rubber sealing ball 57 is increased, so that the force between the rubber sealing ball 57 and the blocking disc 56 is increased, so that the distance between the rubber sealing ball 57 and the blocking disc 56 becomes smaller, and when the gas flows through the gap between the rubber sealing ball 57 and the blocking disc 56, the gas is increased. The force exerted by the body on the rubber sealing ball 57, that is, the air pressure inside the auxiliary storage box 48 is increased. The air pressure inside the auxiliary storage box 48 increases, that is, the force exerted by the air pressure on the rectangular counterweight block 411 increases. During the process of increasing the air pressure on the rectangular counterweight block 411, the paint inside the auxiliary storage box 48 is pushed to flow into the inside of the powder cylinder 1 through the rectangular counterweight block 411, which is conducive to automatically increasing the air pressure inside the space formed by the rectangular counterweight block 411 and the auxiliary storage box 48 when the paint between the piston plate 44 and the partition 41 cannot continue to flow along the inside of the partition 41. The rectangular counterweight block 411 is pushed to move by increasing the air pressure, so that the paint inside the head 8 continues to have pressure, thereby ensuring the continuity of the powder coating on the welding rod;

[0057] When the telescopic rod inside the electric hydraulic push rod 47 begins to extend, the paint inside the transfer storage box 413 flows along the inside of the discharge pipe 414 to between the partition plate 41 and the piston plate 44. At this time, the increase in spatial pressure formed between the rectangular counterweight block 411 and the auxiliary storage box 48 causes the rectangular counterweight block 411 to push the paint inside the auxiliary storage box 48 to continuously apply pressure to the paint inside the machine head 8. At this time, the second connecting rod 46 moves in a direction away from the powder cylinder 1. The movement of the second connecting rod 46 drives the linkage plate 525 and the connecting optical axis 526 to move synchronously. Under the action of the elastic potential energy of the spring 511, the connecting optical axis 526 slides in contact with the upper surface of the baffle plate 517. When the telescopic rod of the electric hydraulic push rod 47 is extended to the limit, the second connecting rod 46 drives the connecting optical axis 526 to move to the end of the baffle plate 517, and under the action of the elastic potential energy of the first spring 511, the rectangular plate 516 moves upward, and the connecting optical axis 526 slides along the end of the baffle plate 517 and the gap inside the rectangular plate 516 until the connecting optical axis 526 moves to the bottom of the baffle plate 517 and fits with the inner wall of the square slide groove 518.

[0058] During this process, the rectangular plate 516 moves upward, so that although the first spring 511 is still in a compressed state, the overall length of the first spring 511 after compression increases, thereby reducing the force applied to the rubber sealing ball 57, and the gap between the gas flowing along the rubber sealing ball 57 and the blocking disc 56 increases, thereby reducing the pressure inside the space formed by the rectangular counterweight block 411 and the auxiliary storage box 48. The electric hydraulic push rod 47 begins to retract when the telescopic rod is extended to the limit, and then continues to make the piston plate 44 squeeze the paint between the partition 41 and the piston plate 44, so that the paint continues to flow to the side of the partition 41 away from the piston plate 44. Under the action of pressure, the paint can continuously coat the welding rod with powder and flow into the auxiliary storage box 48 for storage, which is beneficial when the piston plate 44 extracts the paint inside the transfer storage box 413 and moves to the limit and starts to move in the opposite direction, so that the air pressure in the space formed by the rectangular counterweight block 411 and the auxiliary storage box 48 is automatically reduced. In this process, the paint inside the head 8 is always under pressure, further ensuring the continuity of the powder coating of the welding rod;

[0059] During the process of applying powder to the welding rod, the hand wheel 63 is rotated. The rotation of the hand wheel 63 drives the threaded rod 62 to rotate inside the threaded hole 64. Under the action of the thread, the upper connecting plate 512 can be driven to move on the two support rods 54. The movement of the upper connecting plate 512 can adjust the distance between the upper connecting plate 512 and the lower connecting plate 59, thereby achieving the effect of adjusting the force applied to the rubber sealing ball 57. The difference in force between the rubber sealing ball 57 and the blocking disc 56 makes the air pressure inside the space formed by the auxiliary storage box 48 and the rectangular counterweight block 411 different, which is conducive to adjusting the air pressure inside the auxiliary storage box 48 by rotating the threaded rod 62, avoiding the problem of the first spring 511 weakening after being used for a period of time, thereby ensuring the effect of applying powder to the welding rod;

[0060] During the reciprocating movement of the second connecting rod 46, the movement of the second connecting rod 46 drives the gear rod 76 to move synchronously, and the movement of the gear rod 76 drives the gear 75 meshing with it to rotate. The rotation of the gear 75 drives the rotating shaft 71 to rotate, and then drives the stirring rod 73 to rotate inside the transfer storage box 413. The stirring rod 73 rotates inside the transfer storage box 413, which can stir the paint inside the transfer storage box 413, thereby avoiding the problem of inconvenience in unloading caused by the agglomeration of paint inside the transfer storage box 413.
