In the existing technology, the traditional slurry feeding device mainly has the following technical bottlenecks: static filtration limitations. Existing slurry feeding devices mostly use a fixed filter structure to filter the glass fiber slurry.

Each group of bearing seats 21 is ensured to be coaxial through high-precision processing to ensure the smooth rotation of the threaded rods 22; the gear 24 is arranged at two Between the threaded rods 22, and the gear 24 is engaged with the two threaded rods 22, the two DC motors 23 rotate in the same direction to drive the gear 24 to move left and right.

[0021] As a preferred solution, further, Figure 10 As shown, the cleaning device 3 also includes an electric push rod 36, a rotating rod 37, a spiral groove 38, a cleaning head 39, a cylinder 310 and a slider 311. The electric push rod 36 is arranged in the center of the top surface of the first concave block 33; the rotating rod 37 is arranged at the pushing end of the electric push rod 36 through a rotating shaft, and the rotating shaft has a certain supporting effect on the rotating rod 37, which can make the rotating rod 37 operate stably. The outer wall of the rotating rod 37 is provided with a spiral groove 38, and the spiral groove 38 spirally surrounds the outer wall surface of the rotating rod 37; the cleaning head 39 is arranged at the front end of the rotating rod 37, and the cleaning head 310 is located outside the slurry suction pipe port of the slurry suction pump 4. The cleaning head 310 is designed as a wire cleaning head and has a better cleaning effect; the cylinder 310 is arranged at the second concave block 34 The center of the top surface is formed, and the rotating rod 37 is ringed in the cylinder 310. The outer wall of the rotating rod 37 is at a certain distance from the inner wall of the cylinder 310. The slider 311 is arranged at the front end of the inner wall of the cylinder 310, and the slider 311 is made of wear-resistant material to extend the service life of the equipment. The slider 311 is embedded in the front end of the spiral groove 38, and the cylinder 310 can slide in the spiral groove 38. The electric push rod 36 drives the rotating rod 37 to move forward, and the rotating rod 37 slides on the slider 311 through the spiral groove 38. At the same time, the rotating shaft at the front end of the rotating rod 37 is used to make the rotating rod 37 rotate when it moves forward, thereby driving the cleaning head 310 to move forward into the slurry suction pipe of the slurry suction pump 4, and at the same time, it rotates to clean the glass fiber remaining on the inner wall of the slurry suction pipe into the slurry suction pump 4.

[0022] Initial state: the electric push rod 36 is in a retracted state, the rotating rod 37 is retracted, the cleaning head 39 is located outside the slurry suction pipe orifice, and the slider 311 is located at the rear end of the spiral groove 38; Cleaning process: When cleaning is required, the electric push rod 36 starts and extends forward, pushing the rotating rod 37 to move axially toward the slurry suction pipe; because the slider 311 is embedded in the spiral groove 38, the rotating rod 37 rotates around the axis while moving axially due to the cooperation between the spiral groove 38 and the slider 311, forming a "spiral propulsion" motion; the cleaning head 39 enters the slurry suction pipe with the rotating rod 37, and moves forward while rotating, removing the glass fiber remaining on the inner wall through the friction of the wire brush. The rotary motion ensures that there is no blind spot in the circumference of the pipe wall. After cleaning is completed, the electric push rod 36 contracts in the reverse direction, the rotating rod 37 moves in the reverse direction and rotates along the spiral groove 38, the cleaning head 39 exits the slurry suction pipe, and the residual fibers fall into the storage tank with the centrifugal force or airflow generated by the rotation.

[0023] The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process. The specific operation is as follows: the glass fiber slurry is sucked into the slurry square storage tank 13 through the slurry suction pipe of the slurry suction pump 4. When the glass fiber slurry in the slurry square storage tank 13 reaches a certain storage amount, the glass fiber slurry in the slurry square storage tank 13 is stationary, so that the glass fiber in the slurry is separated from the solid impurity particles, and the glass fiber rises to the top of the slurry, and the solid impurity particles are deposited at the bottom of the slurry. The two threaded rods 22 are driven to rotate in the same direction by two DC motors 23, respectively, so that the gear 24 moves to the left, thereby driving the first filter plate 26 and the second filter plate 27 to move to the left through the moving rod 25, and the first filter plate 26 and the second filter plate 27 are limited to move to the left. 27 collects and filters the solid impurity particles at the bottom of the slurry, and concentrates the solid impurity particles by forming a closed space with the inner wall of the square slurry storage tank 13 to improve the quality of the glass fiber slurry. After stirring, it is output through the metering pump 5. While filtering the glass fiber, the suction pipe of the slurry suction pump 4 is placed on the surface of the third concave block 35, and the electric push rod 36 drives the rotating rod 37 to move forward. Through the cooperation of the rotating shaft at the front end of the electric push rod 36, the rotating rod 37 and the slider 311, the cleaning head 39 can rotate while entering the suction pipe of the slurry suction pump 4, and clean the glass fiber remaining on the inner wall of the suction pipe into the slurry suction pump 4 to prevent the glass fiber remaining on the inner wall of the suction pipe from drying and accumulating, thereby clogging and affecting the service life of the equipment.

[0024] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
