Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to a quantitative mixing device for plastic product manufacturing. Background Technology

[0002] Plastic products are a general term for household and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a type of synthetic polymer material with plasticity. During the production of plastic products, it is often necessary to mix multiple plastic raw materials together, but this mixing requires precise measurement of each raw material.

[0003] In practice, most existing mixing devices for plastic product manufacturing rely on manual feeding, which makes it impossible to accurately measure the materials. This results in plastic products that do not meet usage requirements. Alternatively, manual weighing followed by feeding leads to slow metering and hinders production efficiency. Furthermore, the raw materials cannot be dispersed in time during the mixing process, resulting in uneven mixing and hindering the improvement of plastic product quality. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a quantitative mixing device for plastic product manufacturing, which has the following features:

[0019] Beneficial effects:

[0020] 1. This quantitative mixing device for plastic product manufacturing, through the setup of quantitative bins, quantitative components, and storage hoppers, allows the PLC controller to set the required parameters based on the raw material thresholds needed for plastic product production. This triggers the activation of solenoid valves in each storage bin, allowing the plastic raw material to fall into the quantitative bin. A weighing plate first blocks the falling material, and a weighing sensor monitors the predetermined weight threshold. Once the threshold is reached, the PLC controller issues an operation command to close the solenoid valve, start drive motor A, and rotate the rotating rod, causing the weighing plate to tilt and flip, conveying the plastic raw material into the premixing tank. This achieves precise quantitative mixing, avoiding the problems of manual feeding or manual weighing followed by feeding, which often results in inaccurate material proportioning or slow quantitative speeds, thus improving production efficiency.

[0021] 2. This quantitative mixing device for plastic product manufacturing, through the setting of a premixing component and a dual mixing component, allows for the following operation: When the proportioned plastic product raw materials enter the premixing tank, the drive motor B is started, and the stirring roller rotates to premix the proportioned plastic product raw materials. After premixing, the pneumatic discharge valve is opened to transport the plastic product raw materials into the main body of the mixing tank. The servo motor is then started, and the connecting rod, along with the stirring blades and mixing wheel on the stirring frame, performs dual mixing of the plastic product raw materials. In addition, the scraper strips scrape off the raw materials adhering to the inner wall of the tank, reducing the numerical differences in the mixed raw materials and achieving uniform mixing. This avoids the direct feeding of a fixed amount of plastic product raw materials into the main body of the mixing tank, which can prevent the raw materials from dispersing in time and cause uneven mixing, thus helping to improve the quality of plastic products.

A rotating rod 302 is fixedly connected to one end of the transmission rod, and a weighing plate 303 is fixedly connected to one side of the rotating rod 302. A weighing sensor 304 is installed inside the weighing plate 303. Through the arrangement of the quantitative bin 2, the quantitative assembly 3, and the storage hopper 9, during use, the PLC controller 13 sets the required parameters according to the raw material threshold required for plastic product production, and activates the solenoid valves of each storage bin, allowing the plastic product raw materials to flow down. The material falls into the quantitative bin 2. The weighing plate 303 first blocks it, and the weighing sensor 304 monitors the predetermined weight threshold. After the predetermined threshold is reached, the PLC controller 13 issues an operation command to close the solenoid valve, start the drive motor A301, and rotate the rotating rod 302, which drives the weighing plate 303 to tilt and flip, conveying the plastic product raw material into the premix tank 1. This achieves precise quantitative control, avoiding the need for manual feeding or manual weighing before feeding, which can lead to inaccurate material proportioning or slow quantitative speed, thus improving production efficiency.

The output end of the drive motor B401 is splinedly connected to a transmission rod, and one end of the transmission rod is fixedly connected to a stirring roller 402.

Several stirring blades 804 are fixedly connected to the inner wall of the stirring frame 803. A mixing wheel 805 is fixedly connected to the surface of the connecting rod 802. Through the setup of the premixing assembly 4 and the dual mixing assembly 8, when the proportioned plastic product raw materials enter the premixing tank 1, the drive motor B401 is started, and the stirring roller 402 rotates, first mixing the proportioned plastic product raw materials... The raw materials are premixed. After premixing, the pneumatic discharge valve 6 is opened to transport the plastic product raw materials into the mixing tank body 7. The servo motor 801 is started, and the connecting rod 802 carries the stirring blades 804 and mixing wheel 805 on the stirring frame 803 to perform double stirring and mixing of the plastic product raw materials. In addition, the scraper 12 scrapes off the raw materials adhering to the inner wall of the tank, so as to reduce the numerical difference of the mixed raw materials and achieve the effect of uniform mixing. This avoids the problem of directly putting a certain amount of plastic product raw materials into the mixing tank body 7, which would prevent the raw materials from spreading in time and causing uneven mixing. This helps to improve the quality of plastic products.

[0032] The top of the quantitative bin 2 is fixedly connected to the storage hopper 9. Solenoid valves are fixedly installed on both sides of the storage hopper 9.

[0037] Three mounting blocks are welded to the surface of the main body 7 of the mixing tank, and support legs 15 are welded to the bottom surface of the mounting blocks. The support legs 15 serve to support the main body 7 of the mixing tank.

[0038] In this invention, the working steps of the device are as follows:

[0039] First step: During use, according to the raw material threshold required for plastic product production, the PLC controller 13 sets the required parameters and starts the solenoid valves of each storage bin. The plastic product raw material falls into the quantitative bin 2. The weighing plate 303 first blocks it, and the weighing sensor 304 monitors the predetermined weight threshold. After the predetermined threshold is reached, the PLC controller 13 issues an operation command to close the solenoid valve, start the drive motor A301, and rotate the rotating rod 302, which drives the weighing plate 303 to tilt and flip, conveying the plastic product raw material into the premix tank 1.

In addition, the scraper 12 scrapes off the raw materials adhering to the inner wall of the tank, so as to reduce the numerical difference of the resulting mixed raw materials.
