[0014] A preparation process of a high-performance carboxyl nitrile latex preparation device comprises the following steps: Step 1: The reciprocating screw is driven to rotate by the rotation of the motor, and the rotation of the reciprocating screw drives the thread block to reciprocate up and down, and the reciprocating up and down movement of the thread block drives the elastic telescopic rod to reciprocate up and down, and the elastic telescopic rod reciprocates up and down to cause the arc plate to move up and down; Step 2: scrape the raw materials attached to the inner wall of the reactor by reciprocating up and down the arc plate to prevent the raw materials from adhering to the inner wall of the reactor and forming a thick layer, which affects the heating effect of the spiral heating tube on the carboxyl nitrile latex inside the reactor; Step 3: The elastic telescopic rod moves downward to drive the short rod to move downward, and the short rod moves downward to push the rotating plate to rotate downward. When the short rod is separated from the rotating plate, the No. 1 torsion spring drives the rotating plate to reset, and the limit block resists the rotating plate. When the elastic telescopic rod moves upward, it drives the short rod to move upward. The short rod moves upward and is squeezed by the rotating plate, so that the short rod slides along the rotating plate away from the inner wall of the reactor. Step 4: The short rod slides away from the inner wall of the reactor to drive the free end of the elastic telescopic rod to contract. The contraction of the free end of the elastic telescopic rod drives the arc plate to break away from the contact with the inner wall of the reactor, preventing the elastic telescopic rod from continuously driving the arc plate to scrape the inner wall of the reactor during the upward movement. Long-term scraping may reduce the service life of the reactor.

[0015] The present invention provides a preparation device and a preparation process for high-performance carboxyl nitrile latex, which has the following beneficial effects: (1) The invention scrapes off the raw materials adhered to the inner wall of the reactor by the reciprocating up and down motion of the arc plate, thereby preventing the raw materials from adhering to the inner wall of the reactor and forming a thick layer, which would affect the heating effect of the spiral heating tube on the carboxyl nitrile latex inside the reactor. At the same time, the arc plate is driven out of contact with the inner wall of the reactor by the contraction of the free end of the elastic telescopic rod, thereby preventing the elastic telescopic rod from continuously driving the arc plate to scrape the inner wall of the reactor during the upward movement. Long-term scraping may reduce the service life of the reactor. At the same time, the short rod moves upward and contacts the bump, which pushes the short rod to vibrate, thereby shaking off the raw materials adhered to the arc plate through vibration, thereby preventing the raw materials from adhering to the arc plate and affecting the scraping effect.

[0016] (2) In the present invention, the downward rotation of the rotating plate drives the rotating block to rotate downward, and the downward rotation of the rotating block drives the stirring blade to rotate downward. The stirring blade rotates downward and cooperates with the motor to drive the reciprocating screw to rotate, so as to achieve stirring of the raw materials precipitated at the bottom, thereby preventing the raw materials from precipitating at the bottom of the reactor and affecting the synthesis efficiency of the carboxyl nitrile latex. At the same time, the upward rotation of the rotating block drives the stirring blade to rotate upward. The upward rotation of the stirring blade affects the tilt angle, so that the stirring blade pushes the carboxyl nitrile latex at the bottom of the reactor to flip upward. By moving the carboxyl nitrile latex at the bottom of the reactor upward, precipitation is prevented, thereby affecting the synthesis efficiency.

[0017] (3) In the present invention, the rotation of the rotating plate pushes the connecting seat to move downward, and the downward movement of the connecting seat drives the sliding stirring rod to move downward. The downward movement of the sliding stirring rod cooperates with the rotation of the reciprocating screw to stir the inside of the discharge pipe, thereby preventing the carboxyl nitrile latex from solidifying inside the discharge pipe and affecting the subsequent discharge effect. At the same time, the unblocking rod loses its extrusion and resets under the elastic force of the reset spring itself. The inside of the discharge pipe is unblocked by moving the unblocking rod up and down, thereby preventing the carboxyl nitrile latex from solidifying and causing blockage of the discharge pipe and affecting subsequent use.

The stirring rod 186 stirs the inside of the discharge pipe 4 to prevent the carboxyl nitrile latex from solidifying inside the discharge pipe 4 and affecting the subsequent discharge effect. At the same time, the sliding stirring rod 186 moving downward will push the unblocking rod 188 to move downward. The unblocking rod 188 will unblock the inside of the discharge pipe 4 to prevent the inside of the discharge pipe 4 from being blocked. At the same time, when the sliding stirring rod 186 is reset, the unblocking rod 188 loses its extrusion and will reset under the elastic force of the reset spring 1810 itself. The unblocking rod 188 moves up and down to unblock the inside of the discharge pipe 4 to prevent the carboxyl nitrile latex from solidifying and causing blockage of the discharge pipe 4, which will affect subsequent use.

9. A process for preparing a high-performance carboxylated nitrile latex preparation device, using the high-performance carboxylated nitrile latex preparation device according to claim 8, characterized in that: The following steps are involved: Step 1: The motor (3) rotates to drive the reciprocating screw rod (6) to rotate, the reciprocating screw rod (6) rotates to drive the threaded block (7) to move up and down, the threaded block (7) moves up and down to drive the elastic telescopic rod (9) to move up and down, the elastic telescopic rod (9) moves up and down to drive the arc plate (10) to move up and down; Step 2: scraping the raw materials adhered to the inner wall of the reaction kettle (1) by reciprocating up and down the arc plate (10) to prevent the raw materials from adhering to the inner wall of the reaction kettle (1) and forming a thick layer, thereby affecting the heating effect of the spiral heating tube (5) on the carboxyl nitrile latex inside the reaction kettle (1); Step 3: The elastic telescopic rod (9) moves downward, driving the short rod (12) to move downward. The short rod (12) moves downward, pushing the rotating plate (13) to rotate downward. When the short rod (12) is separated from the rotating plate (13), the first torsion spring drives the rotating plate (13) to reset. At the same time, the limit block (14) abuts against the rotating plate (13). When the elastic telescopic rod (9) moves upward, it drives the short rod (12) to move upward. The short rod (12) moves upward and is squeezed by the rotating plate (13), so that the short rod (12) slides along the rotating plate (13) in a direction away from the inner wall of the reactor (1); Step 4: The short rod (12) slides in a direction away from the inner wall of the reactor (1) to drive the free end of the elastic telescopic rod (9) to contract. The contraction of the free end of the elastic telescopic rod (9) drives the arc plate (10) to break away from the contact with the inner wall of the reactor (1), thereby preventing the elastic telescopic rod (9) from continuously driving the arc plate (10) to scrape the inner wall of the reactor (1) during the upward movement. Long-term scraping will reduce the service life of the reactor (1).
