Description

TECHNICAL FIELD

[0001] The present application relates to the field of injection molding processing, and particularly to a plastic particle color matching device with double feeding function. BACKGROUND

[0002] Currently, in the injection molding production process, how to achieve cost control, improve product quality and meet the requirements of accurate proportioning has become the core challenge of production efficiency and quality stability. With the market's increasing demand for high-quality products and low-cost production, the injection molding industry urgently needs to find a more efficient and accurate proportioning method. However, traditional proportioning methods often rely on manual operation or simple automated equipment, which supply materials through a single feeding port. The biggest problem with this method is that the accuracy of the proportioning cannot be guaranteed, which can easily lead to waste of raw materials and prolong the production cycle.

[0003] Traditional proportioning methods usually use manual measurement or low-precision automatic proportioning systems, and operators add and mix materials based on experience. This method not only depends on the proficiency of the operator, but is also easily disturbed by human factors, leading to uneven proportioning. Especially when different types of materials such as new materials, nozzle materials or auxiliary particle materials need to be mixed, the complexity of the operation increases the probability of proportioning errors. For example, the proportion of nozzle material, which is a recycled material, to new material is usually very strict, and any deviation will affect the performance of the final product. To make up for this deficiency, traditional systems may increase the supply of backup materials, but this leads to waste of raw materials and further increases production costs.

[0004] In addition, traditional proportioning systems usually do not have real-time monitoring and precise control functions, making it difficult to quickly adjust the proportioning ratio during production. Low-level automated equipment cannot dynamically adjust according to production needs, which makes the production cycle longer and affects the efficiency and flexibility of production. For example, during a long production process, the supply of materials may deviate due to system failure, sensor error or changes in raw material properties, causing production interruptions or defective products. Such problems not only reduce the overall efficiency of the production line, but also affect the quality stability of the final product.

[0005] More seriously, traditional proportioning methods usually lack effective material monitoring means. In some situations that require high-precision proportioning, such as the manufacture of special plastic formulations or high-performance products, errors in proportioning can directly affect the quality of the finished product. For example, some special functional additives or pigments must meet extremely precise requirements in proportioning, and any slight deviation can cause the performance of the final product to fail or have cosmetic defects. Therefore, a single proportioning feeding method cannot meet the demands of modern production for high precision, high stability and high efficiency.

[0006] In summary, the traditional batching method has obvious shortcomings in uneven batching, material waste, and long production cycle. To address these challenges, modern injection molding production requires more precise, efficient, and intelligent batching systems to meet the increasingly complex production demands, improve product quality, and effectively control production costs. Utility content

[0007] The purpose of the present application is to overcome at least one deficiency in the prior art, and to provide a plastic particle color matching device with double feeding function. The device can accurately deliver new material and nozzle material or auxiliary material according to the predetermined ratio through the double feeding assembly, and can achieve precise adjustment through the automatic control system. Compared with the traditional single feeding method, double feeding can realize independent supply of materials, avoid batching errors, and ensure accurate mixing of materials during injection molding production.

[0008] To achieve the above-mentioned purpose, the present application discloses a plastic particle color matching device with double feeding function, which comprises a mixing assembly and a toner feeding assembly. The mixing assembly comprises a mixing bin with stirring function and a double feeding mechanism for supplying material to the mixing bin. The mixing bin cooperates with the toner feeding assembly, and the toner feeding assembly feeds toner into the mixing bin. The double feeding mechanism comprises a constant volume bin and a screw conveying unit inserted into the constant volume bin. Specifically, the constant volume bin is provided with an opening and closing controlled feeding port at the top end, which is directly or indirectly connected to the external storage tank or storage bin as the first feeding end. The first material is fed into the constant volume bin through the feeding port. The screw conveying unit serves as the second feeding end and feeds the second material into the constant volume bin through the screw conveying unit. The bottom end of the constant volume bin is connected to the mixing bin through an opening and closing controlled discharge port for feeding material to the mixing bin.

[0009] As an optional technical solution, the screw conveying unit comprises a cylinder inserted into the constant volume bin, a screw inserted into the cylinder, and a driving unit for rotating the screw. One end of the cylinder is open, and the end inserted into the constant volume bin is the discharge end, and the end outside the constant volume bin is the feeding end. Preferably, the screw conveying unit further comprises a hopper or trough located outside the constant volume bin and cooperating with the feeding end.

[0010] As an optional technical solution, a material level sensor is arranged in the constant volume bin.

[0011] As an optional technical solution, the constant volume bin is provided with an observation window for observing the condition in the bin.

[0012] As an optional technical solution, the toner feeding assembly is provided with a weighing sensor to enable the toner feeding assembly to feed based on the weight of the toner.

[0013] As an optional technical solution, the feed inlet in the constant volume bin uses a push-pull type opening and closing mechanism to realize opening and closing control.

[0014] As an optional technical solution, the feed inlet in the constant volume bin uses a push-pull type opening and closing mechanism to realize opening and closing control.

[0015] As an optional technical solution, the constant volume bin has an openable bin door, which facilitates cleaning inside the constant volume bin.

[0016] Compared with the prior art, the present application has at least one of the following beneficial effects:

[0017] 1. Precise material proportioning: Through the design of the double-feed assembly, new material and nozzle material or auxiliary material can be precisely conveyed at the same time, ensuring accurate proportioning of materials during injection molding production. Compared with the traditional single feeding method, this device can independently supply different materials, avoiding the proportioning errors in traditional systems and improving the material mixing precision during production.

[0018] 2. Automatic control and adjustment: The device is equipped with an automatic control system, which can adjust the proportioning of materials in real time according to production needs, thereby realizing more flexible production scheduling and control. Compared with manual operation and low-precision control of traditional batching systems, this device can significantly improve production efficiency, reduce human interference, and reduce operation risks.

[0019] 3. Reduce material waste: Through precise feed control and real-time monitoring inside the constant volume bin, the supply of excess material can be reduced, avoiding raw material waste. Especially in production that requires strict proportioning, this device can effectively control the supply amount of materials, ensuring the accuracy of each batch of materials during production and reducing production costs.

[0020] 4. Improve production stability and reliability: The double-feed design and precise control function of this device can provide stable material supply throughout the production process, effectively reducing production interruptions and defective rates caused by uneven material. By setting the material level sensor and the feed inlet opening and closing control mechanism, the stability of the device is further improved, ensuring continuous and efficient operation during production.

[0030] See attached document Figs. 1-3 This embodiment provides a plastic granule color matching device with dual feeding function, which aims to achieve accurate and automated proportioning of different types of materials.

[0031] The main components of the device include a mixing assembly 1, a toner feeding assembly 2, a constant volume bin 3, a mixing bin 4, a screw conveying unit 5, a feeding port 6, a discharging port 7, a barrel 8, and a driving unit 9. Each component is designed precisely and connected reasonably to effectively ensure the accurate supply and efficient mixing of materials, thereby significantly improving production efficiency and material accuracy.

[0032] Firstly, the mixing assembly 1 is the core component of the entire device, which includes a mixing bin 4 and a stirring function connected to the mixing bin 4. The mixing bin 4 is used to accommodate and stir the materials from the constant volume bin 3 and the toner feeding assembly 2, and ensures uniform mixing of the materials through the stirring function.

[0033] The mixing bin 4 is connected to the toner feeding assembly 2 at the top, which feeds toner by precisely controlling the weight of the toner. The toner feeding assembly 2 is equipped with a weighing sensor that monitors the weight of the toner in real time, ensuring that the supply amount of toner matches the preset ratio accurately. This effectively prevents product quality problems caused by incorrect material ratios, especially in injection molding or plastic forming processes that require precise toner ratios.

[0034] The stirring device in the mixing bin 4 drives the rotation of the stirring rod through the driving unit 9, uniformly mixing different types of plastic particles and toner. One side of the mixing bin 4 is provided with an observation window, which allows the operator to observe the mixing process and confirm the state of the materials, ensuring that the mixing effect meets the production requirements.

[0035] The constant volume bin 3 serves as a material supply and control in the device. The top of the constant volume bin 3 is provided with a feeding port 6, which controls the entry of materials through a push-pull or flap opening and closing control mechanism, ensuring the accuracy and stability of each feeding. The feeding port 6 is connected to an external storage tank or bin, providing the first material (such as new material) for the constant volume bin 3. When the feeding port 6 is opened, the material enters the constant volume bin 3, and the material level in the constant volume bin 3 is monitored in real time by a level sensor, ensuring that the height of the material in the constant volume bin 3 meets the set requirements, avoiding excessive feeding or insufficient material.

[0036] The second feeding end in the constant volume bin 3 is composed of a screw conveying unit 5, which functions to convey the second material (such as nozzle material or auxiliary granular material) to the constant volume bin 3. The design of the screw conveying unit 5 includes a barrel 8, one end of which is inserted into the constant volume bin 3, and the other end is connected to an external hopper or tank. The screw rotates by driving unit 9, conveying the material from the feeding end to the constant volume bin 3. During the screw conveying process, the cooperation between the screw and the barrel 8 can effectively prevent material leakage or blockage, ensuring smooth supply of materials.

[0037] The bottom of the constant volume bin 3 is provided with a discharge port 7 with opening and closing control. The discharge port 7 is connected to the mixing bin 4 through a control mechanism, and is used to accurately send the material in the constant volume bin 3 into the mixing bin 4. Before the material is transported through the discharge port 7 of the constant volume bin 3 to the mixing bin 4, the opening and closing of the discharge port 7 is automatically adjusted by the control system, ensuring that the material enters the mixing bin 4 according to the set ratio, thereby achieving accurate proportioning.

[0038] In addition, the constant volume bin 3 also has an openable bin door, which is designed to facilitate cleaning and maintenance of the inside of the constant volume bin 3. The structure of the constant volume bin 3 allows the operator to easily open the bin door when cleaning is needed, ensuring that there is no material residue inside the device and maintaining the long-term stable operation of the device.

[0039] In actual operation, the toner feeding assembly 2 accurately controls the supply amount of toner through the weighing sensor, the feed port 6 in the constant volume bin 3 controls the supply of new material, and the screw conveying unit 5 is responsible for conveying the nozzle material or auxiliary granular material to the constant volume bin 3. These materials enter the mixing bin 4 through the discharge port 7 of the constant volume bin 3 and are uniformly mixed under the action of the stirring function. Through accurate material proportioning and automatic control system, the device can ensure accurate material supply for each batch during production, significantly reduce human error during production, avoid material waste, and improve production efficiency and product quality.

[0040] For example, during production, the operator adjusts the proportioning of materials as needed, and through the weighing sensor of the toner feeding assembly 2, the material level sensor of the constant volume bin 3, and the drive unit 9 of the screw conveying unit 5, accurate control of different materials is achieved. The device can flexibly adapt to different formula requirements, whether in injection molding, blow molding or other plastic processing fields, it can ensure that the material is supplied on demand, reduce the rate of defective products caused by incorrect material proportioning, and ensure the quality of the products and the stability of the production.

[0041] In summary, the present embodiment provides a high-efficiency, accurate and automated plastic particle color matching device with double feeding function by reasonably designing each component and accurately controlling the material supply. In actual application, the device can effectively improve the automation degree of the production process, ensure the accuracy of material proportioning, reduce material waste, improve production efficiency, and significantly improve the quality of the final product.

Therefore, all changes and modifications are included within the scope of protection of the present disclosure defined by the claims.
