Description

Technical Field

[0001] This utility model relates to the field of plastic color mixing machine technology, specifically a plastic color mixing machine that is easy to clean up residues. Background Technology

[0002] Plastic color mixing machine mainly uses the high-speed rotation of the feeding blades in a vortex to make plastic granules or resin powder roll, collide, rub, and generate heat at high speed, so as to achieve the purpose of color mixing and drying.

[0003] For example, the Chinese authorized patent CN215472298U (A Plastic Color Mixing Machine) includes a tank, a stirring mechanism, an exhaust mechanism, and a heating mechanism. A matching tank cover is hinged to the upper surface of the tank, a support frame is fixedly connected to the lower surface of the tank, and multiple support columns are fixedly connected to the lower surface of the support frame. A hopper is fixedly connected to the side of the tank, and a sliding plate is installed inside the hopper. An annular cavity is formed on the upper surface of the tank, and a matching annular cover is fixedly connected inside the annular cavity. The stirring mechanism includes a motor, a rotating shaft, and a stirring paddle. The motor is installed on the lower surface of the tank. This invention, through its exhaust mechanism, can not only quickly discharge steam but also adsorb and purify the exhaust gas, thereby improving working speed and reducing environmental pollution from exhaust gas.

[0004] However, cleaning the residue adhering to the inner wall of existing plastic color mixing machines is time-consuming and labor-intensive when done by opening the cover, or by using scrapers installed on the material feeding blades to clean the inner wall while rotating. This affects the flow of material along the inner wall of the plastic color mixing machine, and long-term friction can easily damage the scrapers, resulting in a short scraper life. Therefore, this does not meet the current needs. To address this, we propose a plastic color mixing machine that facilitates the cleaning of residue. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic color mixing machine that is easy to clean of residues, in order to solve the problem mentioned in the background art that when cleaning the residues attached to the inner wall of the existing plastic color mixing machine, it is time-consuming and laborious to clean them by opening the cover, or to clean the inner wall by installing a scraper with a material feeding blade while rotating. This will affect the flow of material along the inner wall of the plastic color mixing machine, and long-term friction will easily damage the scraper, resulting in a short scraper life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic color mixing machine that facilitates the cleaning of residues, comprising: a tank body, an adjustment component at the upper end of the tank body, a stepper motor at the lower end of the tank body, a rotating seat at the output end of the stepper motor, the rotating seat being located inside the tank body, material-feeding blades welded to the outer walls of the rotating seat, a moving groove at the center of the material-feeding blades, the moving groove penetrating the material-feeding blades vertically, a discharge pipe on the surface of the tank body near the top, and a sealing plate at one end of the discharge pipe.

[0007] Preferably, the adjusting component includes a cover plate, a through groove is provided at the center of the cover plate, a cylinder is provided at the upper end of the through groove, and the output end of the cylinder moves along the through groove.

[0008] Preferably, the adjustment assembly further includes a movable shaft, the bottom end of which is provided with a ball bearing, and the ball bearing is provided with a rotating sleeve, which is rotatably connected to the movable shaft through the ball bearing.

[0009] Preferably, the rotating sleeve is provided with connecting arms around its perimeter. One end of the connecting arm is heat-fused with a scraper, which moves up and down along the moving groove. The other end of the connecting arm is provided with a fixing bolt, and the connecting arm is threadedly connected to the rotating sleeve through the fixing bolt.

[0010] Preferably, the bottom surface of the cylinder output end and the top surface of the moving shaft are both provided with connecting seats, and the two connecting seats are fixed together by external fasteners.

[0011] Preferably, the top of the tank is provided with snap locks on all four sides, and the tank is fixed to the cover plate by the snap locks.

[0012] Preferably, the lower surface of the tank is provided with support legs on all four sides, and the support legs are welded and fixed to the tank.

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

[0014] (1) This utility model provides a moving groove on the upper surface of the feeding blade. The scraper is driven by the output end of the cylinder to move up and down along the moving groove. During the color mixing operation, the scraper moves up into the moving groove, and the bottom end of the scraper does not contact the inner wall of the tank, so as not to hinder the material from moving along the inner wall of the tank. Since the rotating sleeve is rotatably connected to the moving shaft through ball bearings, and the scraper is located inside the moving groove, when the feeding blade rotates, it drives the scraper to rotate together, keeping the connection position between the scraper and the feeding blade unchanged, and will not cause friction damage to the scraper. After the color mixing is completed, the scraper moves down. The bottom end contacts the inner wall of the tank. The output end of the stepper motor drives the material feeding blade to rotate. When rotating, the scraper cleans the inner wall of the tank, which improves the convenience and flexibility of cleaning and also increases the service life of the scraper. It solves the problem that when cleaning the residue attached to the inner wall of the existing plastic color mixing machine, it is time-consuming and laborious to clean it by opening the cover, or to clean the inner wall by installing a scraper on the feeding blade while rotating. This will affect the flow of material along the inner wall of the plastic color mixing machine, and long-term friction will easily damage the scraper, resulting in a short scraper life.

[0015] (2) By setting connecting seats on the bottom surface of the cylinder output end and the top surface of the moving shaft, and fixing the two connecting seats with external fasteners, the moving shaft and the cylinder output end are fixed, which facilitates the disassembly and replacement of the moving shaft. The connecting arm is connected to the rotating sleeve by fixing bolts, which also facilitates the disassembly and replacement of the scraper. Attached Figure Description
