Description

Technical Field

[0001] This utility model relates to the field of stone-like paint production technology, and in particular to a screening device for stone-like paint production. Background Technology

[0002] Stone-like paint is a colored coating, an industrial exterior wall coating that creates a similar decorative effect to marble and granite. During production, raw materials need to be mixed together, and the solid materials must be sieved to separate out substandard materials. Current sieving equipment for stone-like paint production requires placing the raw materials onto a sieve plate. However, if too much material is placed, it can accumulate, causing even qualified materials to be sieved out if not done promptly. This necessitates re-sieving, impacting production efficiency.

[0003] Publication number CN221017223U discloses a screening device for the production of imitation stone paint. This utility model solves the problem of low screening efficiency in existing screening devices for the production of imitation stone paint. This utility model controls the feed rate through a feeding structure. When in use, the raw material is placed inside the shell. At this time, the inside of the discharge port is blocked by a tilting plate and a rotating shaft, preventing leakage. When screening begins, the motor rotates, driving the rotating shaft to rotate, which in turn drives the tilting plate to rotate. The tilting plate conveys the raw material inside the shell to the inside of the discharge port, achieving quantitative discharge of raw material. This results in more uniform material distribution inside the screen plate, reducing the problem of insufficient screening. When the motor stops rotating, the tilting plate and rotating shaft block the discharge port, stopping the feeding in a timely manner.

[0004] While the above solutions make the material feeding more uniform, the fixed position of the feeding components restricts the replacement of the screen plate, and the raw materials tend to accumulate in a single area on the screen plate. The fixed position of the bin wall vibrator also limits the disturbance effect. Therefore, we propose a screening device for the production of imitation stone paint. Utility Model Content

[0005] The main purpose of this utility model is to provide a screening device for the production of imitation stone paint. By setting up a screening and feeding unit and a disturbance unit, it solves the problems that the fixed position of the feeding component restricts the replacement of the screen plate, and that the raw materials tend to accumulate in a single area on the screen plate. The fixed position of the bin wall vibrator also limits the disturbance effect.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a screening device for the production of imitation stone paint, including a support frame and a support component fixedly installed on the top surface of the support frame, and further including: a screening and feeding unit and a disturbance unit installed on the support component;

[0007] The screening and feeding unit includes a processing box, a screen frame, a storage box, a support arm, and a feeding hopper. The processing box is fixedly installed on the top of the support assembly and is inclined. The screen frame is movably placed inside the top of the processing box. The storage box is fixedly installed on the higher side wall of the processing box. The support arm is L-shaped and one end extends movably into the storage box. The feeding hopper is fixedly installed at the other end of the support arm and located above the screen frame.

[0008] The disturbance unit includes a strip box, a servo motor, a lead screw, a guide block, a support plate, and a vibrator. Two strip boxes are symmetrically fixed on the bottom surface of the processing box, and the strip boxes are parallel to each other. The servo motor is fixed on the inner wall of one of the strip boxes, and the lead screw is fixedly installed at the output end of the servo motor. A strip-shaped limiting groove is opened on one side surface of the bottom end of the strip box. Two guide blocks are located on the strip-shaped limiting groove, and one guide block is threadedly connected to the lead screw. The support plate is fixedly installed on the end face of the guide block, and the vibrator is fixedly installed at the center of the top surface of the support plate, with the vibrator abutting against the bottom surface of the processing box.

[0009] Preferably, there are two support arms located on opposite sides of the hopper, and the storage box is arranged in a one-to-one correspondence with the support arms.

[0010] Preferably, the disturbance unit further includes a guide rod, which is fixedly disposed on the inner wall of another strip box and movably passes through another guide block.

[0011] Preferably, a discharge hopper is fixedly installed at the lower end of the processing box.

[0012] Preferably, the support assembly includes a telescopic rod, a support ring, and a support spring. The telescopic rod is located between the support frame and the processing box.

[0014] Compared with the prior art, the screening device for producing imitation stone paint of this utility model has the following advantages:

[0015] 1. In this utility model, by setting a screening and feeding unit, the processing box, which is fixedly set on the top of the support component and is inclined, can cooperate with the screen frame, which is movably placed at the top of the processing box, to also maintain an inclined placement angle. The support arm, which is fixed on the feeding hopper and is in the shape of an "L", can be inserted into the storage box on the side wall of the processing box. The feeding hopper is positioned above the higher end of the processing box. The raw material introduced into the feeding hopper can fall into the high part of the screen frame and roll out with the help of gravity to avoid accumulation. After the feeding hopper is moved up so that the support arm is pulled out of the storage box, the screen frame can be removed from the processing box without obstruction. The equipment is flexible and easy to disassemble and maintain the feeding component and the screen frame, while ensuring that the raw material is spread out over a large area.

[0016] 2. In this utility model, by setting up a disturbance unit, the servo motor can control the lead screw to rotate forward and backward on the strip box parallel to the processing box. One of the guide blocks, which is threaded to the lead screw, is subjected to force and can drive the vibrator to reciprocate and adjust on the bottom surface of the processing box through the support plate. The area of ​​disturbance of the processing box and screen frame is expanded. The other guide block can slide and move on the guide rod to cooperate with the adjustment of the support plate and the vibrator and provide auxiliary support. The equipment can flexibly adjust the position of the vibrator to ensure that the raw material is fully disturbed to improve the screening effect. Attached Figure Description
