Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stirring equipment, in particular to a stirring device for mixing plastic particles and toner, which can realize efficient and uniform mixing of plastic particles and toner. BACKGROUND

[0002] In the color matching process of plastic particles, the existing technology mainly adopts a rolling stirring structure. These devices realize the mixing of plastic particles and toner through the rotation of stirring rods around a horizontal axis, i.e. a drum-type stirring. However, this stirring method has many deficiencies in practical application, which not only affects the effect of color matching, but also increases the complexity and cost of production.

[0003] Firstly, there is a fundamental problem in the design of the rolling stirring structure: due to the large weight of plastic particles and the small density and light texture of toner, toner is easily lifted by the rotating action of the stirring rods during stirring. This lifting phenomenon causes the toner to not be evenly and firmly attached to the surface of the plastic particles.

[0004] Specifically, the rotation of the stirring rods causes the toner to form a suspended state in the stirring bin, while the plastic particles are deposited at the bottom of the stirring bin due to the action of gravity. This stratification phenomenon reduces the contact area between the toner and the plastic particles, causing the toner to be attached to the surface of the particles in a loose manner with weak bonding force. In actual production, this uneven attachment can cause color differences in the final product, and even cause toner to fall off in some areas, seriously affecting the appearance quality of the product.

[0005] Secondly, another significant problem of the rolling stirring structure is the waste of toner and the inaccuracy of color matching. Due to the easy lifting of toner during stirring, part of the toner will be attached to the inner wall of the stirring bin, especially at the top and side walls of the stirring bin. This attachment phenomenon not only reduces the amount of toner actually involved in the mixing, but also makes it difficult to control the accuracy of color matching. For example, during stirring, the operator needs to add a certain amount of toner according to the formula, but due to the loss of toner, the amount of toner actually involved in the mixing may be much lower than the expected value. In order to achieve the target color, the operator often needs to add toner multiple times, which not only increases the amount of toner, but also may cause deviation in color matching, affecting the consistency of the product. In addition, the toner attached to the inner wall of the stirring bin may fall off and mix into other batches of materials in subsequent production, causing cross contamination and further affecting the accuracy of color matching.

[0006] In addition, the existing mixing bins also have obvious deficiencies in cleaning. Although some technologies use lining structures to facilitate material replacement and cleaning, there are still some problems that are difficult to overcome in their design. For example, there are gaps between the side opening bin door and the main body of the mixing bin, which can easily accumulate a mixture of toner and plastic particles during the mixing process. Even if the bin door can be completely sealed, toner and particles can still remain in the corners and edges of the mixing bin, as well as the gap between the stirring rod and the bin wall. These residues not only are difficult to completely remove, but also can mix with new materials in subsequent production, affecting the accuracy of color matching and the consistency of products. In addition, the process of cleaning the mixing bin usually requires manual operation, which is time-consuming and labor-intensive, and the cleaning effect is difficult to guarantee, which further increases the complexity and cost of production.

[0007] In summary, the existing rolling mixing structure has significant deficiencies in toner adhesion uniformity, color matching accuracy, and cleaning convenience. The root of these problems lies in the design of the mixing structure, which fails to fully consider the differences in physical properties between toner and plastic particles, as well as the sealing and cleaning of the mixing bin. Therefore, it is of great significance and value to develop a new type of mixing device. Invention content

[0008] The purpose of the present application is to at least overcome one deficiency in the prior art, and to provide a mixing device for mixing plastic particles and toner. The device solves the problems of uneven toner adhesion, low color matching accuracy, and inconvenient cleaning in the prior art by optimizing the mixing structure and improving the feeding and discharging methods.

[0009] To achieve the above-mentioned purpose, the present application discloses a mixing device for mixing plastic particles and toner, which comprises a pot-shaped body, a cover, a stirring assembly, and a driving assembly.

[0010] The body is used to contain and mix plastic particles and toner.

The feeding port and the toner inlet are both provided with elastic interfaces to realize sealed connection with external feeding devices or feeding pipes / ports, preventing leakage of materials and toner during transportation.

[0013] The stirring assembly is arranged in the pot-shaped body and comprises a stirring rod composed of a shaft and stirring blades connected to the shaft, forming an anchor-type stirring rod structure.

[0014] The shaft is rotatably connected with the cover through a bearing and is axially constrained on the cover.

The horizontal section is inclined in the horizontal direction to form a first inclined surface, and the vertical section near the top is inclined in the opposite direction to the horizontal section to form a second inclined surface. During stirring, the first inclined surface and the second inclined surface push and crush the toner and the plastic particles to fully mix the toner and the plastic particles and firmly attach the toner to the surface of the particles. This structural design effectively improves the bonding strength of the toner and the particles and ensures the uniformity and accuracy of color matching.

[0016] Further, the upper end of the shaft extends out of the cover and is provided with a protruding pin, and the output shaft of the driving assembly is connected to the protruding pin through a slot joint to achieve rotational driving of the stirring rod.

[0017] Further, the bottom of the body is provided with an opening, and the opening is provided with an opening and closing mechanism. The opening and closing mechanism controls the opening and closing of the opening to achieve the unloading operation of the stirring device.

[0018] Further, the opening and closing mechanism adopts a telescopic structure, including a valve plate and a driving mechanism for driving the valve plate to move horizontally and telescopically. The valve plate moves linearly through the driving mechanism to open and close the opening.

[0019] Further, the cover is provided with a guide plate for guiding the installation of the stirring device to ensure accurate positioning and stable installation of the stirring device in the external installation structure.

[0020] Further, the driving assembly includes a motor and a belt. The motor is provided with a driving wheel, the driving wheel is connected to a driven wheel through the belt, and the driven wheel is connected to the slot joint. The rotational speed of the motor can be adjusted according to actual needs to adapt to the mixing requirements of different materials and toner.

[0021] Further, the body and the cover are made of high-strength wear-resistant materials to prolong the service life and reduce maintenance costs. The inner surfaces of the body and the cover are polished to reduce the adhesion of materials and toner and facilitate cleaning.
