Description

Technical Field

[0001] This application relates to the technical field of paint preparation, and particularly to a device and process for preparing polyester insulating paint. Background Art

[0002] Polyester insulating paint is used for various electronic components and assembled circuit boards, and can be used to protect the circuit boards from being used in various harsh environments such as chemical corrosion, salt spray, humidity, high pollution and dust, vibration, and high and low temperatures. When preparing polyester insulating paint, after the raw materials are fully mixed, it is also necessary to filter out the lumps formed by some paint through filtration.

[0003] In the prior art, the paint is filtered through a sieve. When in use, since the polyester insulating paint is relatively thick and has poor fluidity, during filtration, the paint easily accumulates at one place on the filter screen, resulting in a long time spent on filtering the paint and reducing the efficiency of paint preparation.

[0004] Therefore, the present invention proposes a device and process for preparing polyester insulating paint to improve this problem. Summary of the Invention

A connecting pipe communicating with the connecting sleeve is installed on the piston cylinder. An air inlet pipe is installed on the piston cylinder. A one-way valve is also installed in the air inlet pipe. A piston rod is slidably installed in the piston cylinder. The piston rod is connected to the driving block.

[0014] Further, a hinged rod is hinged on the driving block.

[0019] The present application also provides a process for preparing a polyester insulating varnish, which is prepared by using the polyester insulating varnish preparation device described in any one of the above items, and comprises the following steps:

[0020] S1. Weigh the raw materials according to the reaction ratio and then stir and mix;

[0021] S2, stirring and mixing by increasing the temperature, protecting the raw materials with inert gas during the process, and diluting and adjusting the pH value after the treatment to prepare a paint;

[0022] S3, filtering the prepared paint through a filter plate, and scraping the paint through a scraper plate during filtering to increase the mobility of the paint on the filter plate, so as to facilitate filtering and removing lumps in the paint;

[0023] S4. The paint is sealed after performance testing.

[0024] The beneficial effects of this application are as follows:

[0025] 1. When the present application is in use, the paint is discharged into the containing chamber from the entrance. During the process, the reciprocating sliding of the resistance rod resists the protrusion, so that the filter plate rotates. When the resistance rod releases the resistance to the protrusion, the torsion spring resets the filter plate, so that the filter plate can shake the paint. During the process, the scraper plate scrapes the paint through the cooperation of the driving member, further increasing the mobility of the paint on the filter plate, so that the paint can be spread on the filter plate, which is convenient for filtering the paint, thereby increasing the filtering efficiency of the paint.

[0026] 2. When the device of the present application is in use, when the filter plate is driven to rotate by the resistance rod, the scraper will also be driven to rotate, so that the scraper will not affect the rotation of the filter plate. When the filter plate is reset, the scraper is pushed to reset by the reset of the arc-shaped spring sheet, so that when the device is in use, the scraper and the filter plate will not interfere with each other's work, thereby increasing the feasibility of the device.

[0027] 3. When the present application is in the normal state, the return spring forces the sliding carriage to move away from the channel. Taking the midpoint of the length of the reciprocating lead screw as the reference point, the end of the reciprocating lead screw facing the accommodating cavity is set as the abutting end, and the end away from the accommodating cavity is set as the pulling end. The abutting end is close to the channel while the pulling end is away from the channel. When the driving block moves towards the abutting end, it drives the abutting rod to move into the accommodating cavity, causing it to abut against the convex block, making the filter plate rotate and tilt. When the abutting rod resets, it does not immediately release the abutment against the convex block, keeping the filter plate tilted, providing sufficient time for the movement of the paint. When the driving block moves to the pulling end, the driving block pulls the connecting rope to move away from the channel, causing the connecting rope to pull the sliding block to slide in the accommodating cavity, making the sliding block slide towards the channel to compress the return spring. When the driving block moves to the abutting end again, the connecting rope relaxes, and the return of the return spring pushes the sliding block to reset, enabling the sliding block to drive the entire scraping plate to slide in the accommodating cavity. And through the drive of the reciprocating lead screw, when the abutting rod abuts against the filter plate to rotate, the scraping plate does not slide in the accommodating cavity, and when the scraping plate slides in the accommodating cavity, the abutting rod does not cause the filter plate to rotate. Driving the two alternately enables the scraping plate to have a larger contact area with the filter plate when scraping the paint, thereby increasing the scraping effect of the scraping plate on the paint and enhancing the practicality of the device.

[0028] 4. When the device is in use in the present application, the reciprocating lead screw drives the driving block, and the driving block drives the piston rod to reciprocate, thereby enabling the piston rod to pump air in the piston cylinder. The air flow enters the ventilation pipe through the connecting pipe and the connecting sleeve, and then the air flow blows from the air outlet pipe into the filter holes on the filter plate, blowing the paint located in the filter holes. Since the polyester insulating paint is relatively thick and has poor fluidity, by blowing air, the polyester insulating paint can fall better in the filter holes, and the possibility of the polyester insulating paint stagnating in the filter holes and blocking the filter holes is reduced, enhancing the practicality of the device.

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0044] like Figure 1 - Figure 12 As shown, the present application provides a polyester insulating varnish preparation device and process in Example 1, comprising:

[0045] The installation shell 1 has a receiving cavity 101 formed thereon, and an inlet 102 for communicating with the receiving cavity 101 is formed on the installation shell 1. When in use, the paint is discharged into the receiving cavity 101 through the inlet 102;

[0046] The filter plate 2 is rotatably installed in the accommodating chamber 101. The filter plate 2 and the accommodating chamber 101 are rotatably connected via a rotating shaft. A torsion spring 201 is installed between the rotating shaft of the filter plate 2 and the inner wall of the accommodating chamber 101. The torsion spring 201 drives the filter plate 2 to rotate in the accommodating chamber 101 through its elastic deformation. A protrusion 202 is installed on one side of the filter plate 2. The protrusion 202 is installed on one side of the width direction of the filter plate 2. A plate body is installed on the opposite side of the protrusion 202 in the accommodating chamber 101. The plate body is located below the filter plate 2 and is used to carry the filter plate 2, so that when the filter plate 2 rotates to contact with the plate body, the rotation of the filter plate 2 in this direction is restricted. A resistance rod 203 is slidably installed on the mounting shell 1. The resistance rod 203 is used to resist the protrusion 202 so that the filter plate 2 can rotate in the accommodating chamber 101. When in use, The sliding of the resistance rod 203 causes it to resist the protrusion 202, forcing the filter plate 2 to rotate in the direction of being resisted, so that the filter plate 2 is tilted. At this time, the rod body of the resistance rod 203 still resists the protrusion 202, so that the filter plate 2 can maintain the tilted direction, so that the paint has enough time to move. When the resistance rod 203 is reset to release the resistance with the protrusion 202, the torsion spring 201 is reset to pull the filter plate 2 to reset. When the filter plate 2 is reset to contact with the plate body, the rotation of the filter plate 2 is restricted by the plate body, so that the filter plate 2 is restored to the horizontal direction. When in use, the activity of the paint on the filter plate 2 is increased by the rotation of the filter plate 2, so that the paint can be spread on the filter plate 2, reducing the accumulation of the paint, facilitating the filtration of the paint, and increasing the efficiency of the filtration of the paint.

[0047] The scraper plate 3 is slidably mounted in the accommodating chamber 101. The scraper plate 3 is located above the upper surface of the filter plate 2. A driving member 4 connected to the scraper plate 3 is installed in the accommodating chamber 101. The driving member 4 drives the scraper plate 3 to reciprocate on the filter plate 2. The scraper plate 3 slides along the length direction of the accommodating chamber 101. When in use, the scraper plate 3 slides in the accommodating chamber 101 through the cooperation of the driving member 4. The scraper plate 3 slides alternately with the abutment rod 203. When the abutment rod 203 abuts against the protrusion 202 to reset, the filter plate 2 is in the horizontal direction. At this time, the scraper plate 3 slides to smooth the paint again, further increasing the filtration efficiency of the device for filtering the paint and increasing the practicality of the device.

[0048] Compared with the prior art, during use, the paint is discharged into the accommodating cavity 101 from the inlet 102. During the process, the bump 202 is abutted by the reciprocating sliding of the abutting rod 203, so that the filter plate 2 rotates. When the abutting rod 203 releases the abutment on the bump 202, the torsion spring 201 causes the filter plate 2 to reset, so that the filter plate 2 can shake the paint. During the process, the scraping plate 3 scrapes the paint through the cooperation of the driving member 4, further increasing the mobility of the paint on the filter plate 2, enabling the paint to spread out on the filter plate 2, facilitating the filtration of the paint, and thus increasing the filtration efficiency of the paint. Embodiment 2

[0049] As Figure 3 and Figure 8 shown, Embodiment 2 further discloses the mounting shell 1, the filter plate 2, the scraping plate 3 and the driving member 4 on the basis of Embodiment 1. In Embodiment 2, the scraping plate 3 includes a sliding block 305 slidably mounted in the accommodating cavity 101. The sliding block 305 is slidably mounted in the accommodating cavity 101 along the length direction of the accommodating cavity 101. L-shaped plates are symmetrically mounted in the accommodating cavity 101. The sliding block 305 is slidably mounted between the two L-shaped plates. The sliding block 305 can only slide in a straight line in the accommodating cavity 101 through the shielding of the inner wall of the L-shaped plate;

[0050] A sliding frame 301 is slidably mounted on the sliding block 305 through a connecting spring 306. A cylinder is mounted on the sliding block 305. A rod body is mounted on the sliding frame 301. The end of the rod body is slidably inserted into the cylinder. The connecting spring 306 is located in the cylinder and connected to the rod body to Figure 1 take the main perspective. The sliding block 305 and the sliding frame 301 are slidably connected in the vertical direction;

[0051] A plurality of accommodating shells 302 are linearly arrayed on the sliding frame 301 along the length direction of the accommodating cavity 101. A scraping plate 303 is hinged in the accommodating shell 302. Taking a vertical line passing through the center of the rotating shaft end of the filter plate 2 as the positioning line, the center of the hinge point between the scraping plate 303 and the accommodating shell 302 is also on this positioning line. When the filter plate 2 is tilted, the raised side of it will abut against the scraping plate 303, so that the scraping plate 303 can also rotate with it, so that the scraping plate 303 will not affect the rotation of the filter plate 2;

[0052] An arc-shaped spring piece 304 is installed in the accommodating shell 302. The arc-shaped spring piece 304 contacts the scraper 303. When the scraper 303 rotates with the filter plate 2, the arc-shaped spring piece 304 is pressed against. When the filter plate 2 is reset, the scraper 303 is reset due to the resistance of the arc-shaped spring piece 304. When the filter plate 2 is restored to the horizontal direction, the scraper 303 is also pushed to reset, or the scraper 303 is pushed to rotate to a position where the scraper 303 can contact the paint through a larger area, so that the scraper 303 can push the paint normally.

[0053] When the device is in use, when the filter plate 2 is driven to rotate by the resistance rod 203, the scraper 303 will also be driven to rotate, so that the scraper 303 will not affect the rotation of the filter plate 2. When the filter plate 2 is reset, the scraper 303 is pushed to reset by the reset of the arc-shaped spring piece 304, so that when the device is in use, the scraper 303 and the filter plate 2 will not interfere with each other's work, thereby increasing the feasibility of the device.

[0054] like Figure 3 , Figure 5 and Figure 11 As shown, in the second embodiment, the mounting shell 1 is provided with a mounting cavity 103 connected with the accommodating cavity 101, the driving member 4 includes a reciprocating screw rod 401 rotatably mounted in the mounting cavity 103, a driving motor 8 is installed in the mounting cavity 103, the output shaft of the driving motor 8 is coaxially connected with the reciprocating screw rod 401, the mounting cavity 103 has an opening toward the accommodating cavity 101, and the driving motor 8 is used to drive the reciprocating screw rod 401 to rotate in the mounting cavity 103;

[0055] A driving block 5 is meshed on the reciprocating screw rod 401, and the driving block 5 is slidably matched with the installation cavity 103. The driving block 5 is connected to the resistance rod 203. A groove body is provided in the installation cavity 103, and one end of the driving block 5 is slidably matched with the groove body. The driving block 5 can only slide in the installation cavity 103 along a straight line due to the restriction of the inner wall of the groove body. As a result, when the reciprocating screw rod 401 rotates, the driving block 5 is driven to reciprocate on the reciprocating screw rod 401. The reciprocating motion of the driving block 5 drives the resistance rod 203 to reciprocate in the accommodating cavity 101. A plate body is installed at the end of the resistance rod 203, so that When the resistance rod 203 moves toward the installation cavity 103 and moves to the maximum direction, the opening of the installation cavity 103 is sealed, which reduces the possibility of paint entering the installation cavity 103 and increases the resistance area between the resistance rod 203 and the protrusion 202, so that when the resistance rod 203 slides into the accommodating cavity 101, it can smoothly resist the protrusion 202, ensuring the feasibility of the device. During the process, the resistance rod 203 is not only used to resist the protrusion 202, but also can play the role of a stopper to cover the opening of the installation cavity 103, increasing the practicality of the resistance rod 203;

[0056] A connecting rope 6 is installed on the driving block 5. A channel 7 for the connecting rope 6 to pass through is formed on the mounting shell 1. The channel 7 communicates with the accommodating cavity 101. The free end of the connecting rope 6 passing through the channel 7 and located in the accommodating cavity 101 is connected to the sliding block 305. A return spring 307 is installed between the sliding block 305 and the inner wall of the accommodating cavity 101. The reciprocating lead screw 401 is connected to the sliding block 305 through the driving block 5 and the connecting rope 6, so as to connect the driving member 4 with the scraping plate 3. The inner wall of the channel 7 contacts the connecting rope 6, thereby guiding the connecting rope 6 and playing a guiding role. A plurality of blocks are installed in the installation cavity 103. An arc-shaped groove is formed on the block. The connecting rope 6 is accommodated through the arc-shaped groove, and it also plays a role in fixing and limiting the connecting rope 6, increasing the stability of the connecting rope 6 during use;

[0057] In the normal state, the return spring 307 forces the sliding frame 301 to move away from the channel 7. Taking the midpoint of the length of the reciprocating lead screw 401 as the reference point, the end of the reciprocating lead screw 401 facing the accommodating cavity 101 is set as the abutting end, and the end away from the accommodating cavity 101 is set as the pulling end. The abutting end is close to the channel 7 while the pulling end is far from the channel 7. When the driving block 5 moves towards the abutting end, it drives the abutting rod 203 to move into the accommodating cavity 101, so that it abuts against the convex block 202, causing the filter plate 2 to rotate and tilt. When the abutting rod 203 resets, it will not immediately release the abutment with the convex block 202, so that the filter plate 2 remains tilted, providing sufficient time for the movement of the paint. When the driving block 5 moves to the pulling end, the driving block 5 pulls the connecting rope 6 to move away from the channel 7, so that the connecting rope 6 pulls the sliding block 305 to slide in the accommodating cavity 101, causing the sliding block 305 to slide towards the channel 7 and compress the return spring 307. When the driving block 5 moves to the abutting end again, the connecting rope 6 is relaxed, and the return of the return spring 307 pushes the sliding block 305 to reset, so that the sliding block 305 can drive the entire scraping plate 3 to slide in the accommodating cavity 101, and is driven by the reciprocating lead screw 401, so that when the abutting rod 203 abuts against the filter plate 2 and rotates, the scraping plate 3 will not slide in the accommodating cavity 101. When the scraping plate 3 slides in the accommodating cavity 101, the abutting rod 203 will not cause the filter plate 2 to rotate. The two are alternately driven, so that when the scraping plate 3 scrapes the paint, the filter plate 2 is in the horizontal direction, and there can be a larger contact area between the scraping plate 3 and the filter plate 2, thereby increasing the scraping effect of the scraping plate 3 on the paint and increasing the practicability of the device.

[0058] As Figure 2 and Figure 12As shown, in the second embodiment, a sandwich layer 204 is provided on the filter plate 2. An air vent pipe 206 is installed in the sandwich layer 204. An air outlet pipe 205 passing through the sandwich layer 204 is installed on the air vent pipe 206. A one-way valve is installed in the air outlet pipe 205, which allows the air flow to only move from the inside of the air outlet pipe 205 to the outside of the air outlet pipe 205. The sandwich layer 204 is not only used to install the air vent pipe 206, but also reduces the weight of the filter plate 2, enabling the filter plate 2 to rotate better and increasing the practicality of the device.

[0059] The opening of the air outlet pipe 205 is located in the filter hole on the filter plate 2, and the axis of the air outlet pipe 205 is perpendicular to the axis of the filter hole on the filter plate 2, so that the opening of the air outlet pipe 205 is perpendicular to the opening of the filter hole. When the paint drops from the filter hole, the possibility of the paint entering the air outlet pipe 205 during the drop is reduced, the possibility of the air outlet pipe 205 being blocked is reduced, and the waste of paint is also reduced.

[0060] One side of the filter plate 2 is provided with a connecting sleeve 9 communicating with the air vent pipe 206. The filter plate 2 is rotationally connected to the inner wall of the accommodating cavity 101 through the connecting sleeve 9. The connecting sleeve 9 not only plays the role of ventilation but also can act as a rotating shaft, increasing the practicality of the connecting sleeve 9.

[0061] A piston cylinder 10 is installed in the installation cavity 103. A connecting pipe 11 communicating with the connecting sleeve 9 is installed on the piston cylinder 10. An air inlet pipe 12 is installed on the piston cylinder 10. A one-way valve is also installed in the air inlet pipe 12. A piston rod 13 is slidably installed in the piston cylinder 10. The piston rod 13 is connected to the driving block 5. The one-way valve in the air inlet pipe 12 allows the outside air flow to only enter the piston cylinder 10 unidirectionally.

[0062] When the device is in use, the reciprocating lead screw 401 drives the driving block 5. The driving block 5 drives the piston rod 13 to move reciprocally, so that the piston rod 13 pumps air in the piston cylinder 10. The air flow enters the air vent pipe 206 through the connecting pipe 11 and the connecting sleeve 9, and then the air flow is blown from the air outlet pipe 205 into the filter holes on the filter plate 2 to blow the paint located in the filter holes. Since the polyester insulating paint is relatively thick and has poor fluidity, by means of blowing, the polyester insulating paint can fall better in the filter holes, and the possibility of the polyester insulating paint stagnating in the filter holes and blocking the filter holes is also reduced, increasing the practicality of the device.

[0063] When the air flow blows onto the inner wall of the filter hole, it will be divided into upward and downward air flows. The downward air flow blows the paint to make it move downward, and the upward air flow will contact the paint located above. The upper surface of the filter plate 2 is the place for carrying the paint, so the quality of this part of the paint is relatively large, making the influence of the upward air flow on the paint smaller. And the downward blowing of the air flow provides auxiliary power for the paint to move downward. The main reason for the paint to drop is its own gravity. Therefore, the upward air flow has little influence on the downward feeding of the paint;

[0064] When the paint falls in the filter hole, the first protection is carried out by making the opening of the air outlet pipe 205 perpendicular to the opening of the filter hole. Then, the air outlet pipe 205 blows air to the outside to play the second protection. Finally, the check valve plays the third protection, reducing the possibility of the paint entering the air outlet pipe 205 and increasing the feasibility of the device.

[0065] As Figure 2 and Figure 4 shown, in the second embodiment, a hinge rod 14 is hinged to the driving block 5. A driving gear 15, a transmission gear 16 and an interlocking gear 17 that mesh with each other are rotatably installed in the installation cavity 103. The diameter of the driving gear 15 is larger than that of the transmission gear 16, and the diameter of the transmission gear 16 is larger than that of the interlocking gear 17. The free end of the hinge rod 14 is hinged to the driving gear 15. An interlocking rod 18 is hinged to the interlocking gear 17, and the free end of the interlocking rod 18 is hinged to the piston rod 13. The driving block 5, the hinge rod 14 and the driving gear 15 form a crank - connecting rod structure. When the driving block 5 reciprocates, it drives the position of the free end of the hinge rod 14 to change in the horizontal direction, and the driving gear 15 is pushed or pulled by the hinge rod 14 to rotate. And the interlocking gear 17, the interlocking rod 18 and the piston rod 13 also form a crank - slider structure. When the interlocking gear 17 rotates, it drives the position of the interlocking rod 18 to change in the horizontal direction, and then the piston rod 13 is pushed or pulled by the interlocking rod 18 to reciprocate in the piston cylinder 10 to pump air. The transmission gear 16 transmits the interlocking gear 17 and the driving gear 15. Through the transmission gear 16 to transmit in the middle of the two, when the driving gear 15 rotates, it can drive the interlocking gear 17 to rotate through the transmission gear 16, ensuring that the driving gear 15 can be closer to the driving block 5, and also ensuring that the interlocking gear 17 can be closer to the piston rod 13. Furthermore, the installation distribution of the driving gear 15 and the interlocking gear 17 is more reasonable, enabling the driving block 5 to better drive the driving gear 15 to rotate, and the interlocking gear 17 to better drive the interlocking rod 18 to pull or push the piston rod 13;

[0066] During use, when the driving block 5 reciprocates in the installation cavity 103, the driving gear 15 is driven to rotate through the hinged rod 14, which drives the transmission gear 16 to rotate, and the rotation of the transmission gear 16 drives the connecting gear 17 to rotate, so that the connecting gear 17 rotates and drives the connecting rod 18 to pull or push the piston rod 13. During the process, the driving gear 15 gradually drives the transmission gear 16 and the connecting gear 17 with a smaller diameter than itself, and the large gear drives the small gear, which plays an accelerating role, increases the frequency of the connecting rod 18 driving the piston rod 13, and increases the blowing frequency of the air outlet pipe 205, which further increases the blowing effect of the airflow on the paint in the filter hole.

[0067] like Figure 7 and Figure 8 As shown, in the second embodiment, a rack 19 is installed in the accommodating chamber 101, and an accommodating groove 1901 is provided on the scraper 303. A rotating gear 1902 meshing with the rack 19 is rotatably installed in the accommodating groove 1901. When the scraper 303 slides in the accommodating chamber 101, the rotating gear 1902 and the rack 19 are driven to move relative to each other, and then the rotating gear 1902 is rotated by the meshing of the rack 19 and the rotating gear 1902.

[0068] A pull rope 1903 is wound around the rotating shaft of the rotating gear 1902, and a paint pushing plate 1904 is slidably installed on the scraper 303. A spring is installed between the paint pushing plate 1904 and the scraper 303. In order to facilitate the display of other components, the spring is not shown in the figure. The spring makes the paint pushing plate 1904 move in the direction of the scraper 303 close to the protrusion 202. The paint pushing plate 1904 is connected to the pull rope 1903. The paint pushing plate 1904 slides along the side close to the resistance rod 203 to the side away from the resistance rod 203. A groove body is opened on the scraper 303, and a block that slides with the groove body is installed on the paint pushing plate 1904. The block is restricted by the inner wall of the groove body so that the paint pushing plate 1904 can only slide on the scraper 303 in a straight line direction;

[0069] Since the filter plate 2 rotates only in one direction, when too much paint is added at one time, more paint tends to accumulate on one side of the filter plate 2 near the bump 202. When the scraping plate 3 slides in the receiving cavity 101, the rotating gear 1902 rotates to wind up the pulling rope 1903, causing the paint pushing plate 1904 to move away from the bump 202 to push the paint, so that the paint can be leveled. When the scraping plate 3 resets, the paint pushing plate 1904 also resets through the spring. Since the driving block 5 moves from the pulling end to the abutting end of the reciprocating lead screw 401 in a dynamic process and takes time, this time allows the paint pushing plate 1904 to reset before the filter plate 2 rotates again, so that each time the filter plate 2 returns to the horizontal position, the paint pushing plate 1904 is always on the side of the scraping plate 303 near the bump 202, improving the feasibility of the device. Embodiment III

[0070] As Figure 1 - Figure 12 As shown, Embodiment III further discloses the present application on the basis of Embodiment II. In Embodiment III, a shielding plate 20 is installed in the receiving groove 1901. The shielding plate 20 is rotationally matched with the rotating shaft of the rotating gear 1902. The shielding plate 20 is located above the rotating gear 1902, and the projection of the shielding plate 20 on the bottom of the inner wall of the receiving cavity 101 completely covers the projection of the rotating gear 1902 in the same direction. The shielding plate 20 is used to shield the rotating gear 1902 to reduce the possibility of paint falling on the rotating gear 1902. An inclined surface is provided on the shielding plate 20, and the inclined surface faces away from the receiving groove 1901. Through the guidance of the inclined surface, the paint on the shielding plate 20 falls in the direction away from the receiving groove 1901. Moreover, the shielding plate 20 is rotationally matched with the rotating shaft of the rotating gear 1902 and will not affect the rotation of the rotating gear 1902.

[0071] A brush hair 21 in contact with the rotating gear 1902 is installed on the shielding plate 20. When the rotating gear 1902 rotates, relative movement occurs between it and the brush hair 21. Through the brushing of the brush hair 21 and the centrifugal force generated by the rotating gear 1902 itself, the possibility of paint staying on the rotating gear 1902 is further reduced, increasing the feasibility of the device.

[0072] In Embodiment 3, a plug rod 22 is installed on the driving block 5, and a socket 23 that is slidably engaged with the plug rod 22 is installed on the abutting rod 203. A shielding block 24 for shielding the abutting rod 203 is installed in the installation cavity 103. When the driving block 5 moves towards the pulling end of the reciprocating lead screw 401, the plug rod 22 slides within the socket 23. When the two slide to the maximum extent, the abutting rod 203 and the plate body thereon slide into the installation cavity 103. When the plate body on the abutting rod 203 contacts the shielding block 24, the driving block 5 reaches the end of the pulling end. When the driving block 5 moves towards the abutting end, the plug rod 22 first slides within the socket 23. When the plug rod 22 is inserted to the innermost part of the socket 23, the driving block 5 continues to move towards the abutting end before pushing the abutting rod 203. Through the above settings, the time taken for the driving block 5 to pull the abutting rod 203 is increased, enabling the abutting rod 203 to abut against the convex block 202 for a longer time, further increasing the movement time of the paint on the filter plate 2. Moreover, by shielding the abutting rod 203 with the shielding block 24, the plate body on the abutting rod 203 can be located at the opening of the installation cavity 103 and serve as a cover, and will not continue to move into the installation cavity 103 to affect the operation of its components and the device, thus increasing the practicality of the device.

[0073] In Embodiment 3, an inclined block 25 is installed on the installation shell 1 at the opening of the installation cavity 103. The inclined block 25 is located on the side of the opening of the installation cavity 103 facing the accommodating cavity 101, and the inclined surface of the inclined block 25 faces away from the installation cavity 103. The bottom of the inclined block 25 contacts the upper surface of the abutting rod 203. The inclined block 25 is located above the opening of the installation cavity 103. During use, when the plate body on the abutting rod 203 moves into the installation cavity 103, the bottom of the inclined block 25 scrapes the upper part of the plate body on the abutting rod 203, reducing the possibility of the abutting rod 203 bringing the paint into the installation cavity 103. Moreover, through the guiding of the inclined surface of the inclined block 25, when adding paint, the paint falling on the inclined block 25 will move in a direction away from the opening of the installation cavity 103, reducing the entry of the paint into the installation cavity 103 when the device adds paint;

[0074] One side of the installation shell 1 is installed with a plate body through a hinge to shield the accommodating cavity 101. When the device has been used for a long time, the accommodating cavity 101 is exposed by opening the plate body, facilitating the cleaning of the components and the filter plate 2 in the accommodating cavity 101, thus increasing the practicality of the device.

[0075] As Figure 13 shown, the present application also provides a preparation process for polyester insulating paint, which prepares the polyester insulating paint through the polyester insulating paint preparation device of any one of the above. In some embodiments, it includes the following steps:

[0076] S1. Weigh the raw materials according to the reaction ratio and then stir and mix them;
