Description

Technical Field

[0001] This utility model relates to the field of modified plastics technology, specifically to a raw material pretreatment device for modified plastics production. Background Technology

[0002] Modified plastics refer to plastic products made from general-purpose and engineering plastics through processes such as filling, blending, and reinforcement, which improve their properties such as flame retardancy, strength, impact resistance, and toughness. Modified plastic parts can not only achieve some of the strength properties of steel, but also have a series of advantages such as being lightweight, available in a variety of colors, and easy to mold.

[0003] Before production, modified plastics need to be mixed evenly with plastic granules in a certain ratio to ensure the quality of the finished plastic product. Existing raw material mixing devices have dead zones when mixing modified plastic raw material granules, resulting in unsatisfactory mixing effect and excessive accumulation during mixing, which causes severe separation of the upper and lower parts of the plastic and makes it difficult to mix.

[0004] Therefore, there is a need to provide a raw material pretreatment device for the production of modified plastics. Utility Model Content

[0005] The purpose of this invention is to provide a raw material pretreatment device for modified plastic production, so as to solve the problems mentioned in the background art of poor mixing effect and insufficient mixing between the upper and lower parts when there is too much accumulation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material pretreatment device for modified plastics production, comprising a mounting plate and a cylinder, wherein a stirring mechanism is fixedly mounted on the bottom end face of the cylinder, and a rotating mechanism is fixedly mounted on the fixed end face of the mounting plate; the stirring mechanism includes a fixed frame, a servo motor is fixedly mounted on the inner wall of the fixed frame, a connecting component is fixedly mounted on the end face of the servo motor transmission rod, a connecting rod is fixedly mounted on the end face of the connecting component, a drive motor is fixedly mounted on the end face of the connecting rod, a fixed rod is fixedly mounted on the end face of the drive motor transmission rod, a rotating blade is fixedly mounted on the side of the fixed rod, a fixing strip is fixedly mounted on the side of the drive motor, and a sleeve is fixedly mounted on the side of the fixing strip, the sleeve being sleeved on the outside of the rotating blade.

[0007] Preferably, a stirring blade is fixedly installed on the side of the sleeve, a through hole is fixedly opened on the fixed end face of the cylinder, a feeding port is fixedly installed on the inner wall of the through hole, a cover plate is slidably installed on the inner wall of the feeding port, and a handle is fixedly installed on the side of the cover plate.

[0008] Preferably, the bottom end face of the fixing frame is fixedly connected to the fixed end face of the cylinder.

[0009] Preferably, the rotating mechanism includes a guide ring, the bottom end face of which is fixedly connected to the fixed end face of the mounting plate, a guide rail is slidably installed on the inner wall of the guide ring, a through hole is formed through the guide rail vertically, a limit block is rotatably installed on the inner wall of the through hole, a fixed sleeve is fixedly installed on the fixed end face of the limit block, a sliding groove is fixedly formed on the inner wall of the guide ring, and the inner wall of the sliding groove is slidably connected to the side of the limit block.

[0010] Preferably, a rotor is fixedly installed on the bottom end face of the fixing rod, and the side of the rotor is rotatably connected to the inner wall of the fixing sleeve.

[0011] Preferably, the mounting plate has through holes at the top and bottom, and a discharge pipe is fixedly installed on the inner wall of the through holes, with a valve installed inside the discharge pipe.

[0012] Preferably, a support leg is fixedly installed on the bottom end face of the mounting plate, and an anti-slip pad is fixedly installed on the bottom end face of the support leg.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) In use, the modified plastic raw material pretreatment device for production first adds the modified plastic raw material to be mixed into the cylinder through the feeding port. Then, the servo motor is turned on, which drives the connecting component to rotate. This, in turn, drives the connecting rod and the drive motor to revolve, and causes the sleeve and stirring blades mounted on the side of the drive motor to revolve around the servo motor. At the same time, the drive motor is turned on, which drives the fixed rod to rotate, and then drives the rotating blades mounted on the side of the fixed rod to rotate. This lifts the raw material at the bottom of the cylinder upward and discharges it through the through hole at the top of the sleeve, turning the lower raw material to the upper part. This effectively improves the mixing and stirring effect of the modified plastic raw material and improves the production quality.

[0015] 2) When the mixing mechanism rotates, it drives the rotor to rotate and revolve around the guide ring. During the movement, the rotor first rotates inside the fixed sleeve, adapting to the rotation of the fixed rod. The rotor then drives the limiting block to slide on the inner wall of the chute. When the limiting block moves, it is sleeved by the guide rail, which can prevent the modified plastic raw material from entering the chute and causing the limiting block to get stuck. It effectively adapts to the rotation of the mixing mechanism and improves the service life of the device. Attached Figure Description
