Description

Technical Field

[0001] This utility model relates to the technical field of plastic masterbatch injection molding pretreatment device, and in particular to a plastic masterbatch injection molding pretreatment device. Background Technology

[0002] In the injection molding process of plastic masterbatch, the pretreatment stage has a significant impact on the quality of the injection molded products and production efficiency. However, traditional plastic masterbatch injection molding pretreatment equipment has many problems, which limits the improvement of production level.

[0003] From the perspective of cleaning effectiveness, traditional pretreatment devices rely on a single cleaning method and are not thorough enough. Some devices only use simple immersion cleaning, which is insufficient to remove oil stains, impurities, and other contaminants adhering to the surface of plastic masterbatches. During storage and transportation, plastic masterbatches can become contaminated with various pollutants. If cleaning is incomplete, these impurities can integrate into the plastic products, leading to defects such as rough surfaces and reduced strength, severely affecting product quality and causing instability. Based on this, a plastic masterbatch injection molding pretreatment device is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pretreatment device for plastic masterbatch injection molding. This solves the problem that traditional pretreatment devices often rely on a single cleaning method, resulting in insufficient cleaning. Some devices only employ simple immersion cleaning, which is insufficient to remove oil, impurities, and other contaminants adhering to the surface of the plastic masterbatch. During storage and transportation, plastic masterbatch can become contaminated with various pollutants. If cleaning is incomplete, these impurities can integrate into the plastic products, leading to defects such as rough surfaces and reduced strength, severely impacting product quality and causing instability.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a plastic masterbatch injection molding pretreatment device, comprising a device body, the device body being provided with a connecting mechanism, the connecting mechanism including a traction component disposed at the rear section of the device body, a washing component disposed at the middle section of the device body, and a rewashing component disposed in the inner cavity of the device body.

[0006] The rewashing assembly includes a fixed bracket, a rotating rod fixedly connected to the inner wall of the fixed bracket, a fixed plate fixedly connected to the outer wall of the rotating rod, a connecting rod fixedly connected to the outer wall of the fixed plate, a rotating rod rotatably connected to the upper and lower ends of a sliding connecting block slidably connected to the outer wall of the connecting rod, a rotating blade fixedly connected to the outer wall of the rotating rod, a threaded rod threadedly connected to the inner wall of the bottom of the rotating rod, a rotating block fixedly connected to the bottom of the threaded rod, and inclined baffles fixedly connected to the top of both sides of the inner wall of the device body.

[0007] A further improvement is that the traction assembly includes a drive motor fixedly mounted on the back of the device body, a threaded push rod fixedly connected to the output end of the drive motor, and a fixing frame fixedly connected to the top of the back of the device body.

[0008] A further improvement is that the washing assembly includes a slide plate, a rotating ring is slidably connected to the inner wall of the front side of the slide plate, a meshing toothed ring is fixedly connected to the inner wall of the rotating ring, a meshing gear is meshed to the outer wall of the meshing toothed ring, a spiral rod is fixedly connected to the inner wall of the meshing gear, a threaded sleeve is spirally connected to the outer wall of the middle section of the spiral rod, a connecting spring is sleeved on the outer wall of the lower section of the spiral rod, a rotating cylinder is fixedly connected to the inner wall of the meshing toothed ring, and a material holding cylinder is rotatably connected to the inner wall of the rotating cylinder.

[0010] A further improvement is that the inner wall of the fixed frame is slidably connected to the outer wall of the carriage plate, and the top of the threaded push rod is rotatably connected to the inner wall of the fixed frame. Since the carriage plate is threadedly connected to the outer wall of the threaded push rod, when the threaded push rod rotates, the carriage plate will move along the axial direction of the threaded push rod under the guidance of the fixed frame, thereby realizing the traction of the washing assembly.

[0011] A further improvement is that the slide plate is threadedly connected to the outer wall of the threaded push rod, the block fixed at the bottom of the spiral rod is fixedly connected to the top of the device body, and the material container is used to receive the plastic masterbatch. The cleaning fluid in the inner cavity of the device body is used to clean the plastic masterbatch through the rotating cylinder and the material container. When the rotating cylinder rotates, the plastic masterbatch in the material container will tumble accordingly, and the cleaning fluid in the inner cavity of the device body will perform preliminary cleaning of the plastic masterbatch through the rotating cylinder and the material container.

[0012] A further improvement is that the inclined baffles are provided with equidistant limiting ports, which are used to receive the cleaning fluid in the inner cavity of the device body to clean the plastic masterbatch and prevent the cleaning fluid from splashing. The inclined baffles fixedly connected to the top of both sides of the inner wall of the device body are provided with equidistant limiting ports.

[0014] 1. This utility model's plastic masterbatch injection molding pretreatment device achieves deep cleaning of plastic masterbatch through the ingenious cooperation of the washing component and the re-washing component. In the washing component, the rotating drum drives the material container to rotate, causing the plastic masterbatch to tumble fully in the cleaning solution, initially removing surface impurities. The rotating blades of the re-washing component agitate the cleaning solution, forming a dynamic water flow that thoroughly washes the surface of the masterbatch, completely removing oil stains and stubborn impurities. Through this dual cleaning process, the cleanliness of the plastic masterbatch is greatly improved, providing a strong guarantee for the production of high-quality injection molded products and significantly reducing product defects caused by unclean raw materials.

[0015] 2. The drive motor of the traction component of this utility model precisely controls the movement of the sliding plate of the washing component through a threaded push rod, realizing an automated feeding and washing process. The entire pretreatment process requires no frequent manual intervention, which not only reduces labor costs but also avoids errors caused by manual operation, ensuring consistent washing quality for each batch of plastic masterbatch. Compared with traditional pretreatment methods that rely on manual labor, this greatly shortens the production cycle, significantly improves production efficiency, and helps enterprises gain a competitive edge in the fierce market competition.
