A second rotating rod is rotatably mounted on the driving block in a direction parallel to the first rotating rod. The end of the second rotating rod is provided with a rotating cylinder that cooperates with the moving block. The end of the moving block away from the first rotating rod moves through the rotating cylinder.

[0008] A further feature of this invention is that the radius of the first adjusting gear is smaller than the radius of the second adjusting gear.

[0012] A further feature of this invention is that an elastic wear-resistant layer is provided at the end of the adjusting plate away from the adjusting rod.

[0013] The beneficial effects of this utility model are:

[0014] 1. By setting up adjusting rods and adjusting plates, when the coating inside the reactor is reacting, the adjusting plate is in a horizontal state, and its edge is in contact with the inner wall of the discharge pipe, keeping the discharge pipe closed. When it is necessary to discharge the coating from the reactor, the adjusting mechanism is opened to drive the first adjusting gear to rotate a certain angle according to the required discharge flow rate. This causes the adjusting rod to drive the adjusting plate to rotate a certain angle, so the coating inside the reactor is discharged through the gap between the adjusting plate and the discharge pipe at a certain discharge flow rate. After the coating discharge from the reactor is completed and the reactor is cleaned, the adjusting mechanism... The mechanism drives the adjusting plate to rotate 90° to a vertical position. At this time, the cleaning agent in the vessel body will also flush the two sides of the adjusting plate when it passes through the discharge pipe, thereby washing away the paint adhering to the adjusting plate. Therefore, by setting the adjusting rod and adjusting plate, the rotation angle of the adjusting plate can be adjusted by adjusting the rotation angle of the first adjusting gear, thereby achieving precise adjustment of the discharge flow rate and improving the versatility of the equipment. At the same time, the adjusting plate can be adjusted to a vertical position, which makes it easy to rinse the two sides of the adjusting plate when cleaning the vessel body, and prevent the paint adhering to the adjusting plate from affecting the subsequent discharge process.

[0015] 2. By setting up a bidirectional lead screw, a moving block, etc., when it is necessary to drive the first adjusting gear to rotate a certain angle, the drive motor is first turned on (it should be noted that the drive motor can be a servo motor, which can control the rotation direction and number of rotations of the bidirectional lead screw, which is existing technology, and even without detailed description, it will not affect the understanding of the actual scope of the technology protected by this application by those skilled in the art), driving the bidirectional lead screw to rotate a certain number of rotations, thereby causing the drive block to move a certain distance. When the drive block moves, it causes the moving block, the first rotating rod, and the second adjusting gear to rotate a certain angle, thereby causing the first adjusting gear to rotate a certain angle, thereby realizing the adjustment of the rotation angle of the adjusting plate and realizing the precise adjustment of the paint discharge flow rate.

[0016] 3. By setting a second adjusting gear, and the radius of the second adjusting gear is larger than that of the first adjusting gear, when the second adjusting gear rotates at a certain angle, the rotation angle of the first adjusting gear is greater than that of the second adjusting gear. Therefore, when it is necessary to adjust the adjusting plate from a horizontal state to a vertical state, the second adjusting gear and the moving block need to rotate at an angle of less than 90°, which facilitates the bidirectional screw driving the drive block to move for adjustment.

Detailed Implementation

[0023] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] This utility model provides a discharge structure for a coating reaction vessel, such as... Figures 1 to 4 As shown, the device includes a vessel body 1, a discharge pipe 2 connected to the bottom of the vessel body 1, and an adjusting rod 3 rotatably disposed within the discharge pipe 2 in a horizontal direction. Adjusting plates 4 are symmetrically arranged on the adjusting rod 3. When the adjusting plates 4 are in a horizontal direction, the ends of the adjusting plates 4 are movably attached to the inner wall of the discharge pipe 2. One end of the adjusting rod 3 is located on the outside of the discharge pipe 2, and a first adjusting gear 5 is vertically arranged at the end of the adjusting rod 3. An adjusting mechanism 6 for adjusting the rotation angle of the first adjusting gear 5 is provided on the outer wall of the discharge pipe 2.

[0025] Furthermore, the adjustment mechanism 6 includes a first rotating rod 6a rotatably disposed on the outer wall of the discharge pipe 2 in a direction parallel to the adjustment rod 3, and a second adjusting gear 6b ​​disposed vertically on the first rotating rod 6a. The first adjusting gear 6a meshes with the second adjusting gear 6b. A moving block 7 is disposed at the end of the first rotating rod 6a in a vertical direction. A driving mechanism 8 for pushing the moving block 7 is disposed on the outer wall of the discharge pipe 2.

[0026] Furthermore, the driving mechanism 8 includes a bidirectional lead screw 8a rotatably mounted on the outer wall of the discharge pipe 2 in a horizontal direction and a driving block 8b cooperating on the bidirectional lead screw 8a. The discharge pipe 2 is provided with a driving motor 9 for driving the bidirectional lead screw 8a to rotate. The driving block 8b is provided with a second rotating rod 10 rotatably mounted in a direction parallel to the first rotating rod 6a. The end of the second rotating rod 10 is provided with a rotating cylinder 11 that cooperates with the moving block 7. The end of the moving block 7 away from the first rotating rod 6a moves through the rotating cylinder 11.

[0027] Furthermore, the radius of the first adjusting gear 5 is smaller than the radius of the second adjusting gear 6b.

[0028] Furthermore, the movable block 7 is rod-shaped.

[0029] Furthermore, an indicator rod 12 is provided on the adjusting rod 3 in a direction parallel to the adjusting plate 4, and the indicator rod 12 is located on the outside of the discharge pipe 2.

[0030] Furthermore, the cross-sectional area of ​​the end of the adjusting plate 4 closest to the adjusting rod 3 is greater than the cross-sectional area of ​​the end of the adjusting plate 4 furthest from the adjusting rod 3, and the longitudinal section of the adjusting plate 4 is triangular.

[0031] Furthermore, an elastic wear-resistant layer 13 is provided at the end of the adjusting plate 4 away from the adjusting rod 3.

[0032] When the coating material inside the reactor 1 is reacting, the regulating plate 4 is in a horizontal state. At this time, the elastic wear-resistant layer 13 on the edge of the regulating plate 4 is attached to the inner wall of the discharge pipe 2, so that the discharge pipe 2 is in a closed state. When it is necessary to discharge the coating material inside the reactor 1, according to the required discharge flow rate, the drive motor 9 is turned on to drive the bidirectional lead screw 8a to rotate a certain number of turns, thereby driving the drive block 8b to move a certain distance. When the drive block 8b moves, it drives the moving block 7, the first rotating rod 6a, and the second regulating gear 6b ​​to rotate a certain angle, thereby driving the first regulating gear 5 to rotate a certain angle. Therefore, the coating material inside the reactor 1 is discharged through the gap between the regulating plate 4 and the discharge pipe 2 at a certain discharge flow rate. When the coating material inside the reactor 1... After the discharge is completed and the inside of the vessel 1 is cleaned, the drive motor 9 is turned on to drive the adjusting plate 4 to rotate 90° to a vertical position. At this time, the cleaning agent in the vessel 1 will also flush the two sides of the adjusting plate 4 when it passes through the discharge pipe 2, thereby washing away the paint adhering to the adjusting plate 4. Therefore, by setting the adjusting rod 3, adjusting plate 4, etc., on the one hand, the rotation angle of the adjusting plate 4 can be adjusted by adjusting the rotation angle of the first adjusting gear 5, thereby achieving precise adjustment of the discharge flow rate and improving the versatility of the equipment; on the other hand, the adjusting plate 4 can be adjusted to a vertical position, which is convenient for rinsing the two side walls of the adjusting plate 4 when cleaning the vessel 1, and avoids the paint adhering to the adjusting plate 4 from affecting the subsequent discharge process.

[0033] By setting up a bidirectional lead screw 8a, a moving block 7, etc., when it is necessary to drive the first adjusting gear 5 to rotate a certain angle, the drive motor 9 is first turned on (it should be noted that the drive motor 9 can be a servo motor, which can control the rotation direction and number of rotations of the bidirectional lead screw 8a. This is prior art, and even without detailed description, it will not affect the understanding of the actual scope of the technology protected by this application by those skilled in the art). The bidirectional lead screw 8a is driven to rotate a certain number of times, thereby causing the drive block 8b to move a certain distance. When the drive block 8b moves, it causes the moving block 7, the first rotating rod 6a, and the second adjusting gear 6b ​​to rotate a certain angle, thereby causing the first adjusting gear 5 to rotate a certain angle, thereby realizing the adjustment of the rotation angle of the adjusting plate 4 and realizing the precise adjustment of the paint discharge flow rate.

[0034] By setting a second adjusting gear 6b, and since the radius of the second adjusting gear 6b ​​is larger than that of the first adjusting gear 5, when the second adjusting gear 6b ​​rotates at a certain angle, the rotation angle of the first adjusting gear 5 is greater than that of the second adjusting gear 6b. Therefore, when it is necessary to adjust the adjusting plate 4 from a horizontal state to a vertical state, the angle that the second adjusting gear 6b ​​and the moving block 7 need to rotate is less than 90°, reducing the distance that the driving block 8b needs to move, thereby facilitating the bidirectional lead screw 8a to drive the driving block 8b to move for adjustment.

[0035] By setting up the indicator rod 12, the position of the adjusting plate 4 inside the discharge pipe 2 can be indicated, making it easier for workers to observe.

[0036] By setting the longitudinal section of the adjusting plate 4 to a triangle, the paint adhering to the adjusting plate 4 can slide down the inclined surface of the adjusting plate 4, thereby reducing the adhesion of paint on the adjusting plate 4.

[0037] By setting the elastic wear-resistant layer 13, on the one hand, the sealing between the adjusting plate 4 and the discharge pipe 2 is increased when the adjusting plate 4 is in a horizontal state; on the other hand, the inner wall of the discharge pipe 2 is prevented from being scratched during the rotation of the adjusting plate 4.

[0038] It should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0039] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
