Description

Technical Field

[0001] This utility model relates to the field of putty powder production and screening technology, specifically a multi-stage screening device for putty powder production. Background Technology

[0002] Putty powder is usually composed of base material, filler, water, and additives. Base material, also known as adhesive, is the most important component of putty. Its main functions are bonding, leveling, and repair. The most commonly used materials are cement and polymer materials. Organic polymer materials can be divided into emulsion and emulsion powder. During processing, they need to be sieved to prevent the powder from drying and clumping, which would affect its use.

[0003] Currently, existing screening equipment for putty powder production mostly screens out the finer particles first during the screening process. These are mostly horizontal vibration screening devices. During the screening process, the larger particles of putty powder are very likely to cause the screen to get clogged, thus affecting the effective screening. To address this, we have proposed a multi-stage screening device for putty powder production. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-stage screening device for putty powder production, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A multi-stage screening device for putty powder production includes a base plate and a housing. A motor base is fixedly installed on the bottom of one side of the housing, and a first servo motor is fixedly installed on the top of the motor base. The output end of the first servo motor extends into the interior of the housing and a roller is fixedly installed thereon. A fine screen is provided inside the roller, a medium screen is provided inside the roller and on one side of the fine screen, and a large screen is provided inside the roller and on one side of the medium screen. Two partitions are fixedly installed inside the housing. Several hoppers are fixedly installed at the bottom of the housing, and a discharge cylinder is fixedly installed at the bottom of each hopper. A support foot is fixedly installed on one side of the top of the base plate and is rotatably connected to the housing. A hydraulic telescopic rod is fixedly installed on the top of the base plate. A groove is opened inside the bottom of the motor base, and a sliding rod is fixedly installed inside the groove. A slider is slidably installed on the outside of the sliding rod, and the hydraulic telescopic rod is movably connected to the slider.

[0006] Preferably, a feeding hopper is fixedly installed on one side of the housing, and a feeding cylinder is fixedly installed inside the side of the housing. The bottom of the feeding hopper is fixedly connected to the top of the feeding cylinder. An inlet is opened inside the top of the feeding cylinder. A second servo motor is fixedly installed on one side of the feeding cylinder. The output end of the second servo motor extends into the inside of the feeding cylinder and a feeding spiral blade is installed. A discharge port is opened inside the bottom of the feeding cylinder.

[0007] Preferably, a discharge pipe is fixedly installed on one side of the housing and below the feeding cylinder, and the roller cooperates with the discharge pipe.

[0008] Preferably, one end of the feeding cylinder extends into the interior of the drum.

[0009] Preferably, the slider has a hole inside that mates with the slide rod, and the slider is slidably connected to the inner wall of the slide groove.

[0010] Preferably, a controller is provided on one side of the housing.

[0011] This utility model provides a multi-stage screening device for putty powder production, which has the following beneficial effects:

[0012] 1. This multi-stage screening equipment for putty powder production utilizes a first servo motor, a drum, a fine screen, a medium screen, a large screen, a partition, a hopper, a discharge cylinder, support feet, a hydraulic telescopic rod, a chute, a slide bar, and a slider. During the screening process, the first servo motor drives the drum to rotate, causing the putty powder inside the drum to rotate and pass through the fine screen for finer particle size screening. The screened putty powder is then discharged through the hopper and discharge cylinder. After the fine-particle putty powder has been screened, opening the hydraulic telescopic rod allows it to retract, slightly tilting the casing. This moves the putty powder inside the fine screen to the medium screen, where it can then be screened step by step. This screening method allows the putty powder to roll and screen, avoiding screen blockage caused by vibration, and also results in high screening efficiency.

[0013] 2. This multi-stage screening equipment for putty powder production, through the cooperation of a feeding hopper, feeding cylinder, feed inlet, second servo motor, feeding spiral blades and discharge port, can drive the feeding spiral blades to rotate by turning on the second servo motor according to screening requirements, so that the unscreened putty powder can be evenly added to the inside of the drum for screening, avoiding the situation where too much putty powder is added at one time and the accumulation affects the screening efficiency.
