Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, specifically a plastic masterbatch screening machine. Background Technology

[0002] Plastic masterbatch screening machines are generally used for screening plastic masterbatches. They primarily use vibration to force the masterbatches through a screening mesh, achieving layer-by-layer screening. To address the issue of screening masterbatches from largest to smallest, the mesh size of the screen increases as the screening progresses. However, in the final screening step, excessively fine pores reduce screening efficiency. Furthermore, an excessive number of masterbatches can easily cause blockages in the upper screening sections, hindering the discharge and collection of masterbatches. Patent document CN 219025005U discloses a plastic masterbatch screening machine, which includes a motor base, control panel, switch button, power connector, vibrating mounting plate, mounting support rod, fixing sleeve, vibrating screen plate, screening screen, sealing cover, collection cover, guide base plate, discharge port, rotary screen mechanism, rotary motor, rotary shaft, and screen cover. The plastic masterbatch passes through the screen cover for the final screening step. The high-speed rotation of the screen cover enables the final screening step of the plastic masterbatch to be carried out quickly, improving the screening efficiency of plastic masterbatch and preventing the occurrence of blockage at the top. While achieving high-speed screening of plastic masterbatch, it also discharges plastic masterbatch more quickly, making it convenient for the discharge, collection, and use of plastic masterbatch.

[0003] However, the existing technology has the following drawbacks: although the stacking and installation of multiple vibrating screens is beneficial for multi-layer screening, the operation is more complicated when the screening screen needs to be cleaned or replaced. The upper vibrating screens need to be disassembled one by one in order to maintain the lower screening screen, which consumes a lot of time and manpower. Utility Model Content

[0004] This utility model mainly provides a plastic masterbatch screening machine, which solves the problem that existing technology requires disassembling the upper vibrating screen plate in sequence in order to maintain the lower screening screen, which consumes a lot of time and manpower.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A plastic masterbatch screening machine includes a vibrating mounting plate, mounting support rods, a vibrating screen plate, a collecting hood, and a screening screen. Both the vibrating screen plate and the collecting hood are fitted with square outer shells. Multiple mounting support rods are symmetrically arranged on the vibrating mounting plate corresponding to both sides of the square outer shells. Each side of the mounting support rods is equipped with multiple stabilizing frames. The square outer shell is detachably connected to two stabilizing frames on the same layer. Specifically, the components of the rotary screen mechanism are mounted on the collecting hood of this application, which is consistent with the installation on existing collecting hoods in the prior art. Simultaneously, the discharge port is directly mounted on the collecting hood of this application, penetrating the square outer shell mounted thereon. Specifically, the output shaft of the rotary motor of the rotary screen mechanism is detachably connected to the rotating shaft penetrating the guide base using any existing method. The guide base is located at the bottom of the circular inner shell of the collecting hood. In use, the square outer shell of each vibrating screen or collecting cover is detachably connected to two stabilizing frames on the same layer, thus utilizing the stabilizing frames for support. When maintenance or other work is required on the corresponding layer's vibrating screen, it can be directly removed from the stabilizing frame and taken out from the side without the support rod installed; conversely, it can be installed. Using this structure, the vibrating screen and collecting cover achieve independent disassembly of each layer through the detachable connection between the square outer shell and the stabilizing frame. During maintenance, there is no need to disassemble the upper layer components; the target layer screen can be directly removed from the side, significantly shortening maintenance time and reducing the difficulty of manual operation.

[0007] Furthermore, the stabilizing frame has a limiting groove, and the lower side of the square outer shell is provided with a limiting strip that matches the limiting groove. The limiting strip and the limiting groove are detachably connected by bolts. This structure, with the bolted connection between the limiting strip and the limiting groove, ensures the stability of the equipment during operation and prevents vibration from causing components to loosen.

[0008] Furthermore, a funnel-shaped feeding channel is provided below the vibrating screen plate. This funnel-shaped feeding channel restricts the feeding port to the upper opening range of the next circular inner shell, thereby preventing material from entering between the circular inner shell and the directional outer shell.

[0009] Furthermore, the outer side of the vibrating screen disc or collecting cover is provided with an upper mating groove and a lower mating groove. A circular dustproof mesh cover is fitted onto the upper mating groove. After the circular dustproof mesh cover is moved upward, it is detachably connected to the lower mating groove of the upper circular inner shell. With this structure, the detachable sealing design of the circular dustproof mesh cover and the upper mating groove effectively prevents impurities from entering and material leakage, and allows observation of the material accumulation on the vibrating screen disc, thereby enabling timely removal of this layer of the vibrating screen disc for maintenance.

[0010] Furthermore, the circular dustproof mesh cover is detachably connected to the upper lower mating groove via a positioning screw. This structure allows the circular dustproof mesh cover to be fixed onto the upper lower mating groove.

[0011] Beneficial effects: The vibrating screen and the collecting cover are detachably connected to the stabilizer through the square outer shell, which enables independent disassembly of a single layer; during maintenance, there is no need to disassemble the upper part, and the target layer screen can be directly removed from the side, which greatly shortens the maintenance time and reduces the difficulty of manual operation.

[0018] like Figure 1 , Figure 2 , Figure 3As shown, in the plastic masterbatch screening machine of this embodiment, the vibrating screen and collecting hood include a square outer shell 6 and a circular inner shell disposed within the square outer shell 6. The screening screen 5 is disposed at the bottom of the circular inner shell corresponding to the vibrating screen 3. Multiple mounting support rods 2 are symmetrically arranged on the vibrating mounting plate 1 on both sides of the square outer shell 6. Multiple stabilizing frames 7 are disposed on each side of the mounting support rod 2. The square outer shell 6 is detachably connected to two stabilizing frames 7 on the same layer. Specifically, each component of the rotary screening mechanism is installed in the circular inner shell corresponding to the collecting hood 4 of this application, which is consistent with the installation on the existing collecting hood in the prior art. At the same time, the discharge port is directly installed on the circular inner shell corresponding to the collecting hood 4 of this application for communication. Specifically, the output shaft of the rotary screening mechanism's rotary motor and the rotary shaft penetrating the guide base are detachably connected in any existing manner. The guide base is disposed at the bottom of the circular inner shell of the collecting hood 4. The stabilizing frame 7 has a limiting groove, and the lower side of the square outer shell 6 is provided with a limiting strip 8 that matches the limiting groove. The limiting strip 8 and the limiting groove are detachably connected by bolts. A funnel-shaped feeding channel 9 is provided at the lower position of the circular inner shell. The outer side of the circular inner shell has an upper mating groove 10 and a lower mating groove 11. A circular dustproof net cover 12 is fitted on the upper mating groove 10. After the circular dustproof net cover 12 is moved up, it is detachably connected to the lower mating groove 11 of the upper circular inner shell. The circular dustproof net cover 12 is detachably connected to the upper circular inner shell by a positioning screw 13. In use, the square outer shell 6 of each vibrating screen 3 or collecting cover 4 can be detachably connected to the two stabilizing frames 7 on the same layer, thereby using the stabilizing frames 7 for support. When maintenance or other work is required on the corresponding layer of vibrating screen 3, it can be directly removed from the stabilizing frame 7 and taken out from the side where the support rod 2 was not installed; otherwise, it can be installed. With this structure, the vibrating screen plate 3 and the collection cover 4 are detachably connected to the stabilizer 7 through the square outer shell 6, realizing independent disassembly of a single layer; during maintenance, there is no need to disassemble the upper layer components, and the target layer screen plate can be directly removed from the side, which greatly shortens the maintenance time and reduces the difficulty of manual operation.
