Description

Technical Field

[0001] The present application relates to the field of capacitor processing technology, and in particular to a flexible capacitor spraying device and a spraying process thereof. Background Art

[0002] A flexible capacitor is a capacitor with variable shape and flexibility. It uses a composite of multiple materials such as polymer materials, conductive materials and electrolytes to make a capacitor with flexibility and deformation properties. Flexible capacitors can be bent, stretched, twisted and other deformations as needed without affecting performance. They can be used in flexible electronic products. In the production process of flexible capacitors, electrodes are usually made by spraying conductive materials, which requires the use of a suitable sprayer for electrode spraying.

[0003] Among them, there is a sprayer that uses a plunger pump for spraying operations. It mainly forms a low-pressure environment in the pump cylinder during the return stroke of the piston in the plunger pump, thereby drawing the paint into the pump cylinder, and then presses the paint to the spray gun through the plunger pump, so that the spray gun sprays the paint evenly to the product.

[0004] During this process, if there are too many solid particles in the paint and the solvent evaporates too quickly, the paint is prone to agglomeration and precipitation and clogging the spray gun, especially when the paint is left to stand for too long. This problem is more obvious. For this reason, the paint needs to be stirred and heated between spraying (the heating temperature is different for different paints) to avoid agglomeration and precipitation, improve the fluidity and coating performance of the paint, and improve the spraying effect. Existing heating and stirring devices for paint mostly place the paint in a large-volume cylinder, use traditional electric heating wire heating, and stirring blades for stirring, which makes the overall heating time of the paint too long and the stirring time will also be extended. Long-term stirring will lead to an increase in the solvent volatilization rate of the paint, a decrease in viscosity, and an oxidation reaction between the paint and the air, etc., resulting in a decrease in the overall performance of the paint. If the amount of loaded paint is reduced, the heating efficiency and stirring efficiency will be improved, but this will easily lead to the problem of insufficient paint, affecting the efficiency of spraying. Summary of the Invention

[0005] The present application proposes a flexible capacitor spraying device and a spraying process thereof, which has the advantages that the coating liquid is diverted through the through hole, the heating plate quickly heats the diverted coating liquid, the coating liquid squeezes the heating plate to move the heating plate, the hot air flow impacts the impeller to drive the rotating rod to rotate the extrusion block, the extrusion block intermittently squeezes the slider II, thereby pushing the slider I and the push rod to move, the spring pushes the heating plate to one side through the push rod to reset, the heating plate performs a linear reciprocating motion, the heating plate shears and stirs the surrounding coating liquid, the rolling ball I squeezes and collides with the rolling ball II, and stirs and shears the surrounding coating liquid, so as to solve the problems of existing coating agglomeration and precipitation and the long-term heating and stirring of the coating by the sprayer.

A hot air cavity is provided in the heating plate, and a symmetrical air inlet pipe and air outlet pipe are fixedly connected to the outer wall of the heating plate. The air inlet pipe and the air outlet pipe are both connected to the hot air cavity for introducing and discharging hot gas to form a flow state of hot air flow.

[0010] Preferably, the diameter of the heating plate is smaller than the diameter of the annular groove, so as to provide space for the heating plate to move.

[0012] Preferably, a transition hole is provided in the extension seat, and a connecting hole is provided between the movable hole and the transition hole, which is used to guide the hot air flow input by the air outlet pipe into the transition hole. A rotating rod is provided in the transition hole, and an impeller is provided on the rotating rod for receiving the power of the hot air flow to drive the rotating rod to rotate. An extrusion block is provided at one end of the rotating rod.

[0013] Preferably, a sliding cavity I is provided in the extension seat, a slider I is movably sleeved in the sliding cavity I, one end of the slider I is fixedly connected to a spring, the same end of the slider I is fixedly connected to a push rod, one end of the push rod passes through the extension seat and the pump cylinder to the annular groove, and the end of the push rod located in the annular groove is in contact with the outer wall of the heating plate, so as to receive the power of the heating plate or change the movement direction of the heating plate.

[0014] Preferably, a sliding cavity II is provided in the extension seat, a slider II is movably sleeved in the sliding cavity II, and one end of the rotating rod connected to the extrusion block is located in the sliding cavity II.

[0015] Preferably, the end of the slider I close to the slider II has an inclined surface I, and the end of the slider II close to the slider I has an inclined surface II. The inclined surface I and the inclined surface II are in a fitted state, and are used to change the positions of the slider I and the slider II. The end of the slider II close to the extrusion block has an inclined surface III, which is used to receive the power when the extrusion block rotates.

[0016] Preferably, a hot air duct is provided on the pump cylinder, and the hot air duct is spirally wrapped around the pump cylinder for heating and keeping warm the material in the piston cavity.

[0017] Preferably, the piston chamber is hinged with evenly distributed rolling balls II at one end close to the liquid inlet channel, and the heating plate is hinged with evenly distributed rolling balls I at one end close to the rolling balls II. The rolling balls I and II are staggered and are used for extrusion and collision when the heating plate moves.

[0018] A spraying process for a flexible capacitor spraying device comprises the following steps:

[0019] S1. The plunger rod drives the plunger to move toward the air inlet channel, expanding the liquid cavity and reducing the pressure in the liquid cavity. Valve I is opened, allowing the coating liquid to be sucked into the liquid cavity from the liquid inlet channel. The coating liquid flows through the through hole toward the plunger. The hot gas in the heating plate heats the coating liquid passing through the through hole and simultaneously heats the coating liquid around the heating plate.

[0020] S2. At the same time, the gas cavity shrinks, causing the pressure inside the gas cavity to increase, opening valve IV, and the hot air flow in the gas cavity to be discharged from the gas cavity through the exhaust channel;

[0021] S3. Then, the plunger rod drives the plunger to move toward the liquid inlet channel, shrinking the liquid cavity and increasing the pressure in the liquid cavity. Valve I is closed and valve II is opened, so that the coating liquid is discharged from the liquid cavity from the liquid outlet channel. The coating liquid flows through the through hole toward the liquid outlet channel, and the coating liquid squeezes the through hole, pushing the heating plate toward the extension seat. The heating plate squeezes the ejector rod, pushing the slider I toward the sliding cavity II, so that the slider I pushes the slider II away from the movable hole. At this time, the spring is stretched.

[0022] S4. At the same time, the gas cavity expands, reducing the pressure in the gas cavity. Valve IV is closed and valve III is opened, allowing the hot gas in the heating plate to enter the gas cavity through the extension seat, the hot air channel and the air inlet channel under suction. The subsequent hot air flow is replenished into the hot air cavity from the air inlet pipe. The hot air flow in the heating plate heats the coating liquid passing through the through hole and heats the coating liquid around the heating plate at the same time.

[0023] S5. When the hot air flows into the extension seat, it passes through the movable hole and the connecting hole and enters the transition hole. The hot air flows through the impeller, pushing the impeller to rotate, causing the impeller to drive the rotating rod and the extrusion block to rotate;

[0024] S6. The rotating extrusion block intermittently squeezes the inclined surface III of the slider II, pushing the slider II to move toward the movable hole, so that the inclined surface II on the slider II squeezes the inclined surface I of the slider I, and the stretched spring pushes the push rod, so that the push rod pushes the heating plate to move toward the air inlet pipe;

[0025] S7. With this reciprocating motion, the heating plate will perform a linear reciprocating motion. During this process, the rolling ball I will collide and rub with the rolling ball II, and both the rolling ball I and the rolling ball II will rotate.

[0026] This application has the following beneficial effects:

[0027] The present application provides a flexible capacitor spraying device, which sucks the coating liquid into the liquid cavity through a plunger and discharges it from the liquid cavity under the push of the plunger, so that the liquid is diverted twice through the through hole on the heating plate, so that a small part of the liquid can be directly heated by the heating plate, thereby improving the heating efficiency of the liquid and shortening the heating time of the liquid.

[0028] At the same time, through the reciprocating motion of the plunger, the plunger absorbs the hot air flow into the gas chamber, causing the hot air flow in the heating plate to flow rapidly, so that the diverted liquid passing through the through hole can receive more heating from the hot air flow per unit time, further improving the heating efficiency of the coating liquid.

[0029] At the same time, when the liquid in the liquid chamber is discharged from the liquid chamber under the pressure of the plunger, the liquid flowing through the through-hole on the heating plate will be affected by the inclined flow channel of the through-hole, so that the high-pressure liquid squeezes the through-hole, pushing the heating plate to move in the direction of the extension seat, causing the heating plate to squeeze the push rod and push the slider I to move in the direction of the sliding chamber II. At this time, the spring is stretched and energy is stored, and the slider I will push the slider II to move to the side away from the sliding chamber I. At the same time, the hot air flow flowing rapidly by the movement of the plunger will pass into the transition hole, so that the fast-flowing hot air flow will impact the impeller, so that the impeller drives the rotating rod to rotate, and the rotating rod drives the extrusion block to rotate, so that the extrusion block intermittently squeezes on the inclined surface III of the slider II, pushing the slider II to reset in the direction of the sliding chamber I, so that the slider II is squeezed on the inclined surface I of the slider I, thereby cooperating with the stretched spring to push the push rod to squeeze the heating plate, so that the heating plate is reset to the side away from the extension seat, and this reciprocating motion makes the heating plate do a linear reciprocating motion, so that the position of the through-hole on the heating plate is constantly changed, and the surrounding coating liquid is sheared and stirred.

[0030] At the same time, when the heating plate makes a linear reciprocating motion, the rolling ball I on the heating plate will be squeezed and collided with the rolling ball II on the end of the piston chamber close to the heating plate, so that the rolling balls I and II are rolled and engaged, and the surrounding paint liquid is ground and stirred under the squeezing and collision of the rolling balls I and II, which further improves the stirring effect of the paint liquid. At the same time, it also avoids the problem that the paint liquid that does not pass through the through hole cannot be efficiently sheared, stirred and heated.

[0031] At the same time, when the heating plate performs linear reciprocating motion, the liquid ejected from the through-hole of rolling ball II will impact rolling ball II at this location, causing the coating liquid to disperse under the impact and pass through the channel with reduced space (the channel between rolling ball II and the heating plate and the channel formed between rolling ball I and rolling ball II), subjecting it to additional squeezing, thereby further improving the dispersion effect of the coating and enabling the coating liquid to achieve efficient stirring effect in a short time.

Example

[0044] See also Figures 1 to 3A flexible capacitor spraying device includes a pump cylinder 1, a piston chamber 2 is provided in the pump cylinder 1, a liquid inlet channel 5 and a liquid outlet channel 7 are provided at one end of the pump cylinder 1, a valve I6 is provided in the liquid inlet channel 5, and a valve II8 is provided in the liquid outlet channel 7, so that when the plunger 3 moves in a direction away from the liquid inlet channel 5, the space of the liquid chamber 201 will become larger, the pressure here is reduced, the valve I6 is opened under the pressure difference, the valve II8 is closed, and the coating liquid enters the liquid chamber 201 through the opened liquid inlet channel 5, so that when the plunger 3 moves in the direction of the liquid inlet channel 5, the space of the liquid chamber 201 will become smaller, the pressure here is increased, the valve II8 is opened under the pressure difference, the valve I6 is closed, and the coating liquid is discharged from the liquid chamber 201 through the opened liquid outlet channel 7, and the other end of the pump cylinder 1 is provided with a valve I6. There are an air inlet channel 9 and an air exhaust channel 11. A valve III 10 is provided in the air inlet channel 9, and a valve IV 12 is provided in the exhaust channel 11. When the plunger 3 moves in the direction away from the liquid inlet channel 5, the space of the gas chamber 202 will become smaller, and the pressure here will increase, so that the valve IV 12 will open under the pressure difference, and the valve III 10 will close, so that the hot gas in the gas chamber 202 will be discharged from the gas chamber 202 through the opened exhaust channel 11. When the plunger 3 moves in the direction of the liquid inlet channel 5, the space of the gas chamber 202 will become larger, and the pressure here will decrease, so that the valve III 10 will open under the pressure difference, and the valve IV 12 will close, so that the hot gas will enter the gas chamber 202 through the opened air inlet channel 9, so that the hot gas in the heating plate 14, the extension seat 20 and the hot air duct 33 will form a flowing airflow.

[0045] See Figure 2 A plunger 3 is movably sleeved in the piston chamber 2, and a plunger rod 4 is fixedly connected to the center of one end of the plunger 3 near the air inlet channel 9. The other end of the plunger rod 4 passes through the center of one end of the pump cylinder 1 and is connected to the existing power device. The power device can select an existing eccentric wheel power device, a hydraulic transmission device, etc., so that the plunger rod 4 drives the plunger 3 to reciprocate in the piston chamber 2 under the drive of the power device, thereby changing the space size in the piston chamber 2 and providing a pressure difference environment. The piston chamber 2 is divided into a liquid chamber 201 and a gas chamber 202 from the plunger 3. The liquid chamber 201 is connected to the liquid inlet channel 5 and the liquid outlet channel 7, and the gas chamber 202 is connected to the air inlet channel 9 and the exhaust channel 11, providing sufficient space for the paint liquid and hot gas.

[0046] See Figures 2 to 3 , Figures 5 and 6, an annular groove 13 is provided on the inner wall of the piston chamber 2 near the liquid inlet channel 5, and a heating plate 14 is movably sleeved in the annular groove 13. The diameter of the heating plate 14 is smaller than the diameter of the annular groove 13, so that the annular groove 13 can provide sufficient activity space for the heating plate 14, and a hot air cavity 18 is provided in the heating plate 14. A symmetrical air inlet pipe 15 and an air outlet pipe 16 are fixedly connected to the outer wall of the heating plate 14. The air inlet pipe 15 and the air outlet pipe 16 are both connected to the hot air cavity 18. The air inlet pipe 15 passes through the pump cylinder 1 and is connected to the existing hot air flow conveying device, so that the hot air flow can enter the hot air cavity 18 from the air inlet pipe 15 and then discharge the hot air cavity 18 from the air outlet pipe 16, so that the heating plate 14 can efficiently heat the surrounding paint liquid. The heating plate 14 is provided with uniformly distributed The through hole 17 requires the coating liquid to pass through the through hole 17 when passing through the heating plate 14, so that a large amount of coating liquid is divided into multiple small flow fluids by the through hole 17, so that the heating plate 14 can directly heat the small flow liquid, thereby improving the heating efficiency when the heat input of the hot air flow remains unchanged and the liquid input flow rate is reduced. The through hole 17 is inclined toward the air outlet pipe 16, so that when the plunger 3 squeezes the coating liquid out of the liquid cavity 101, the high-pressure liquid will be squeezed on the inner wall of the through hole 17 when passing through the through hole 17. Affected by the inclination of the through hole 17, the liquid provides a greater force on the heating plate 14 toward the air outlet pipe 16, causing the heating plate 14 to move toward the air outlet pipe 16 under the pressure of the liquid.

[0047] See Figures 1 to 4 An extension seat 20 is fixedly connected to the pump cylinder 1, and a movable hole 21 is opened at the bottom of the extension seat 20. The air outlet pipe 16 passes through the pump cylinder 1 and is inserted into the movable hole 21. The air inlet pipe 15 and the air outlet pipe 16 are both movably connected to the pump cylinder 1, and the air inlet pipe 15 and the air outlet pipe 16 are both provided with sealing rings to prevent the air inlet pipe 15 and the air outlet pipe 16 from leaking when they follow the heating plate 14 for linear reciprocating motion. The air outlet pipe 16 is located at one end of the movable hole 21 away from the end of the movable hole 21 away from the pump cylinder 1, so that the movable hole 21 can provide sufficient movable space for the air outlet pipe 16.

[0048] See Figure 4 A transition hole 22 is provided in the extension seat 20, and a connecting hole 23 is provided between the movable hole 21 and the transition hole 22. A rotating rod 26 is movably sleeved in the extension seat 20, and the center line of the rotating rod 26 coincides with the center line of the transition hole 22. An impeller 28 is fixedly sleeved on the rotating rod 26, and one end of the rotating rod 26 is fixedly connected to an extrusion block 27, so that when the hot air flow enters the transition hole 22 and flows toward the hot air duct 33, the hot air flow will impact the impeller 28, causing the impeller 28 to rotate under force, thereby driving the rotating rod 26 and the extrusion block 27 to rotate synchronously.

[0049] See Figure 4, a sliding cavity Ⅰ 24 is opened in the extension seat 20, and a slider Ⅰ 29 is movably sleeved in the sliding cavity Ⅰ 24. An inclined surface Ⅰ is provided on one side of the slider Ⅰ 29, so that the inclined surface Ⅰ on the slider Ⅰ 29 can contact the inclined surface Ⅱ on the slider Ⅱ 32, so that when the slider Ⅰ 29 is pushed by the heating plate 14, the inclined surface Ⅰ can squeeze the inclined surface Ⅱ on the slider Ⅱ 32 through the inclined surface Ⅰ, pushing the slider Ⅱ 32 to move away from the movable hole 21. One end of the slider Ⅰ 29 is fixedly connected to a spring 31, and the other end of the spring 31 is away from the sliding cavity Ⅰ 24. One end of the sliding chamber II 25 is fixedly connected, and the end of the slider I 29 close to the pump cylinder 1 is fixedly connected to a push rod 30, and the end of the push rod 30 close to the pump cylinder 1 passes through the extension seat 20 and the pump cylinder 1 to the annular groove 13, and the end of the push rod 30 located in the annular groove 13 is in contact with the outer wall of the heating plate 14, so that when the heating plate 14 moves toward the air outlet pipe 16, the heating plate 14 will squeeze the push rod 30, so that the push rod 30 pushes the slider I 29 to move away from the pump cylinder 1. At this time, the spring 31 will stretch and store energy, and a sealing ring is provided on the push rod 30.

[0050] See Figure 4 , a sliding cavity II 25 is opened in the extension seat 20, the movable cavity I 24 and the sliding cavity II 25 are connected, the cross-section of the movable cavity I 24 and the sliding cavity II 25 forms an L shape, and a slider II 32 is movably sleeved in the sliding cavity II 25. The end of the slider 32 close to the slider I 29 has an inclined surface II, and the inclined surface II is in contact with the inclined surface I on the slider I 29. The other end of the slider II 32 has an inclined surface III. One end of the rotating rod 26 connected to the extrusion block 27 is located in the sliding cavity II 25, and the edge of the extrusion block 27 is rounded, so that the extrusion block 27 can intermittently squeeze when it rotates. On the inclined surface III of the slider II 32, the extrusion block 27 pushes the slider II 32 to move in the direction of the movable hole 21, so that the slider II 32 squeezes the inclined surface I of the slider I 29 through the inclined surface II, and cooperates with the stretched spring 31 to push the slider I 29 and the push rod 30 toward the heating plate 14, so that the heating plate 14 is squeezed and moves away from the extension seat 20. After the extrusion block 27 leaves the slider II 32, the high-pressure coating liquid will push the heating plate 14 to move in the direction of the extension seat 20 again, and this reciprocating motion will cause the heating plate 14 to perform a linear reciprocating motion.

[0051] See Figures 1 to 4 A hot air duct 33 is fixedly connected to the pump cylinder 1. The hot air duct 33 is spirally wrapped around the pump cylinder 1. One end of the hot air duct 33 is connected to the transition chamber 22, and the other end is connected to the air inlet channel 9, so that the hot air flow can enter the air inlet channel 9 from the transition hole 22 through the hot air channel 33. At the same time, the hot air flow passing through the hot air channel 33 will heat and keep the paint liquid in the piston chamber 2 warm. Example

[0052] See also Figures 2 to 3 , Figure 7 The piston chamber 2 is hinged at one end near the liquid inlet channel 5 with uniformly distributed rolling balls II 191, and the heating disk 14 is hinged at one end near the rolling balls II 191 with uniformly distributed rolling balls I 19. The rolling balls I 19 and II 191 are staggered. When the heating disk 14 makes a linear reciprocating motion, the rolling balls I 19 on the heating disk 14 will be squeezed and collided with the rolling balls II 191, so that the rolling balls I 19 and II 191 rotate and engage with each other, so that the surrounding paint liquid is ground and stirred under the squeezing and collision of the rolling balls I 19 and II 191, further improving the stirring effect of the paint liquid. At the same time, it also avoids the problem that the paint liquid that has not passed through the through hole 17 cannot be efficiently sheared, stirred and heated.

[0053] A spraying process for a flexible capacitor spraying device comprises the following steps:

[0054] S1, the plunger rod 4 drives the plunger 3 to move toward the air inlet channel 9, so that the liquid chamber 201 expands and the pressure in the liquid chamber 201 decreases, opening the valve I6, so that the coating liquid is sucked into the liquid chamber 201 from the liquid inlet channel 5, and the coating liquid flows through the through hole 17 toward the plunger 3. The hot gas in the heating plate 14 heats the coating liquid passing through the through hole 17, and at the same time heats the coating liquid around the heating plate 14;

[0055] S2. At the same time, the gas cavity 202 shrinks, causing the pressure inside the gas cavity 202 to increase, opening the valve IV 12, and the hot air flow in the gas cavity 202 is discharged from the gas cavity 202 through the exhaust channel 11;

[0056] S3. Then, the plunger rod 4 drives the plunger 3 to move toward the liquid inlet channel 5, shrinking the liquid chamber 201 and increasing the pressure in the liquid chamber 201. The valve I6 is closed and the valve II8 is opened, allowing the coating liquid to be discharged from the liquid chamber 201 through the liquid outlet channel 7. The coating liquid flows through the through hole 17 toward the liquid outlet channel 7, squeezing the through hole 17 and pushing the heating plate 14 toward the extension seat 20. The heating plate 14 squeezes the ejector rod 30, pushing the slider I 29 toward the sliding chamber II 25. The slider I 29 pushes the slider II 32 away from the movable hole 21. At this time, the spring 31 is stretched.

[0057] S4. At the same time, the gas cavity 202 increases, reducing the pressure in the gas cavity 202. The valve IV 12 is closed, and the valve III 10 is opened. The hot gas in the heating plate 14 enters the gas cavity 202 through the extension seat 20, the hot air channel 33, and the air inlet channel 9 under suction. The subsequent hot air flow is replenished into the hot air cavity 18 from the air inlet pipe 15. The hot air flow in the heating plate 14 heats the coating liquid passing through the through hole 17, and also heats the coating liquid around the heating plate 14.

[0058] S5. When the hot air flows into the extension seat 20, it passes through the movable hole 21 and the connecting hole 23 and enters the transition hole 22. The hot air flows through the impeller 28, pushing the impeller 28 to rotate, causing the impeller 28 to drive the rotating rod 26 and the extrusion block 27 to rotate;

[0059] S6. The rotating extrusion block 27 intermittently squeezes the inclined surface III of the slider II 32, pushing the slider II 32 toward the movable hole 21, so that the inclined surface II of the slider II 32 squeezes the inclined surface I of the slider I 29, and the stretched spring 31 pushes the push rod 30, so that the push rod 30 pushes the heating plate 14 toward the air inlet pipe 15;

[0060] S7. With this reciprocating motion, the heating plate 14 will perform a linear reciprocating motion. During this process, the rolling ball I 19 will collide and rub with the rolling ball II 191, and both the rolling ball I 19 and the rolling ball II 191 will rotate.

7. A spraying process for a flexible capacitor spraying device, characterized in that: The following steps are involved: S1, the plunger rod (4) drives the plunger (3) to move in the direction of the air inlet channel (9), so that the liquid chamber (201) expands, the pressure in the liquid chamber (201) decreases, and the valve I (6) is opened, so that the coating liquid is sucked into the liquid chamber (201) from the liquid inlet channel (5), and the coating liquid flows through the through hole (17) toward the plunger (3). The hot gas in the heating plate (14) heats the coating liquid passing through the through hole (17), and at the same time heats the coating liquid around the heating plate (14); S2. At the same time, the gas cavity (202) shrinks, causing the pressure in the gas cavity (202) to increase, opening the valve IV (12), and allowing the hot air flow in the gas cavity (202) to be discharged from the gas cavity (202) through the exhaust passage (11); S3. Then, the plunger rod (4) drives the plunger (3) to move in the direction of the liquid inlet channel (5), so that the liquid chamber (201) shrinks and the pressure in the liquid chamber (201) increases. The valve I (6) is closed and the valve II (8) is opened, so that the coating liquid is discharged from the liquid chamber (201) from the liquid outlet channel (7). The coating liquid flows through the through hole (17) in the direction of the liquid outlet channel (7), and the coating liquid is squeezed through the through hole (17), pushing the heating plate (14) to move in the direction of the extension seat (20). The heating plate (14) squeezes the ejector rod (30) and pushes the slider I (29) to move in the direction of the sliding chamber II (25), so that the slider I (29) pushes the slider II (32) to move in the direction away from the movable hole (21). At this time, the spring (31) is stretched; S4. At the same time, the gas cavity (202) increases, so that the pressure in the gas cavity (202) decreases, the valve IV (12) is closed, and the valve III (10) is opened, so that the hot gas in the heating plate (14) enters the gas cavity (202) through the extension seat (20), the hot air duct (33) and the air inlet channel (9) under suction, and the subsequent hot air flow is replenished into the hot air cavity (18) from the air inlet pipe (15). The hot air flow flowing in the heating plate (14) heats the coating liquid passing through the through hole (17) and heats the coating liquid around the heating plate (14); S5. When the hot air flow enters the extension seat (20), it enters the transition hole (22) through the movable hole (21) and the connecting hole (23). The hot air flow passes through the impeller (28), pushing the impeller (28) to rotate, causing the impeller (28) to drive the rotating rod (26) and the extrusion block (27) to rotate; S6, the rotating extrusion block (27) intermittently squeezes the inclined surface III of the slider II (32), pushing the slider II (32) to move in the direction close to the movable hole (21), so that the inclined surface II on the slider II (32) squeezes the inclined surface I of the slider I (29), and cooperates with the stretched spring (31) to push the push rod (30), so that the push rod (30) pushes the heating plate (14) to move in the direction of the air inlet pipe (15); S7. With this reciprocating motion, the heating plate (14) will perform a linear reciprocating motion. During this process, the rolling ball I (19) will collide and rub with the rolling ball II (191), and both the rolling ball I (19) and the rolling ball II (191) will rotate.
