Description

Technical Field

[0001] This utility model relates to the field of material mixing, and in particular to a component for controlling uniform mixing of preform injection head. Background Technology

[0002] Mixing refers to the process of mixing multiple materials in a certain proportion and according to process requirements to obtain a uniform and stable mixture. This process is very common in industries such as material processing, chemical industry, and food industry. Its purpose is to make the material properties more uniform and meet the requirements of the production process.

[0003] The preform injection head mixing uniformity control component is a device used to ensure uniform mixing of raw materials during the injection molding process.

[0004] The existing preform injection head mixing uniformity control component has the following shortcomings: In the preform production process, plastic raw materials need to be fully mixed with various additives. Therefore, the mixing uniformity control component has become a core piece of equipment. However, existing technologies often face thorny problems. Plastic raw materials are prone to blockage in the feed pipe. This not only interrupts the continuous production rhythm and causes work stoppage, but may also cause local overheating and agglomeration due to the accumulation of raw materials. This affects the uniformity of subsequent mixing and increases equipment maintenance costs, seriously restricting production efficiency and product quality stability. Utility Model Content

[0005] This invention ensures efficient coordination between the feeding and discharging processes, providing a stable guarantee for production continuity and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a preform injection head mixing uniform control component, comprising an integral mechanism, the top of which is fixedly connected to an auxiliary mechanism; the integral mechanism includes a first support plate and a second support plate, the outer wall of the second support plate is rotatably connected to a first pulley and a second pulley respectively, the inner walls of the first pulley and the second pulley are fitted with synchronous belts, a mixing tank is penetrated through the outer wall of the first support plate, a feed pipe is fixedly connected to the outer wall of the mixing tank, a first threaded blade is movably inserted into the inner wall of the feed pipe, a gear pump is fixedly connected to the bottom of the mixing tank, a discharge pipe is fixedly connected to the bottom of the gear pump, a first rotating rod is movably inserted into the inner wall of the discharge pipe, and a second threaded blade is fixedly connected to the outer wall of the first rotating rod. Through the above component, an integrated process from raw material feeding, mixing to conveying is realized, and the first threaded blade in the feed pipe can push the raw material to be conveyed, reducing blockage.

[0007] Preferably, anti-slip pads are fixedly connected to the bottom of the first support plate and the second support plate, and a PLC controller is fixedly installed on the front of the first support plate. The PLC controller is electrically connected to the components to control the opening and closing of the components.

[0008] Preferably, an electric heating rod is fixedly installed on the inner wall of the mixing tank. The synchronous belt is connected to the first pulley and the second pulley through frictional transmission. The outer wall of the first threaded blade is fixedly connected to the outer wall of the first pulley. One end of the first rotating rod is fixedly connected to the outer wall of the second pulley. The electric heating rod can heat the material in the mixing tank, reduce the hardness of the plastic raw material, enhance its compatibility with additives, and improve the uniformity of mixing.

[0009] Preferably, a first servo motor is fixedly installed on the outer wall of the second support plate. The output end of the first servo motor is fixedly connected to the outer wall of the second pulley. The first servo motor provides power to the second pulley and drives the first and second threaded blades to rotate synchronously through belt transmission. The speed of the first servo motor is adjustable, and the conveying speed can be flexibly adjusted according to the characteristics of the raw materials (such as particle size and flowability) to adapt to the processing needs of different raw materials and improve the versatility of the equipment.

[0010] Preferably, the outer wall of the discharge pipe is fixedly connected to the injection head body, and a set of temperature sensors is fixedly installed on the top of the mixing tank. The detection end of the temperature sensor penetrates the pipe wall of the mixing tank and extends into its interior. The temperature sensor monitors the material temperature in the mixing tank in real time to avoid raw material degradation due to excessively high temperature or affecting the mixing effect due to excessively low temperature. It provides temperature feedback to the PLC controller to achieve precise temperature control and ensure stable material performance.

[0011] Preferably, a second rotating rod is movably inserted into the inner wall of the mixing tank, and a stirring rod is fixedly connected to the outer wall of the second rotating rod. A set of flexible scrapers is fixedly connected to the outer wall of the stirring rod. A second servo motor is fixedly installed on the top of the mixing tank, and the output end of the second servo motor is fixedly connected to one end of the second rotating rod. The second servo motor drives the second rotating rod and the stirring rod to rotate, thereby forcibly stirring the material and improving the mixing uniformity. The flexible scrapers can scrape off the raw materials adhering to the inner wall of the mixing tank, avoiding material residue and clumping, reducing waste and lowering the difficulty of cleaning.

[0012] Preferably, the auxiliary mechanism includes a metering pump, the input end of which is fixedly connected to a connecting pipe. The metering pump is connected to the interior of the mixing tank. With the cooperation of the metering pump and the connecting pipe, additives can be delivered into the mixing tank. The amount of additives delivered can be precisely controlled to ensure accurate ratio of raw materials and additives, avoid fluctuations in preform quality (such as uneven color and performance) caused by ratio deviation, improve product consistency, and meet the needs of high-precision production.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, in the overall mechanism, the first servo motor can drive the second pulley to rotate, thereby driving the second rotating rod and the second threaded blade to rotate synchronously. At the same time, with the help of the synchronous belt transmission, the first pulley and the first threaded blade are driven to rotate through the belt transmission mechanism. This design allows the first threaded blade to rotate continuously in the feed pipe, which can actively push the raw material to be transported smoothly, reducing the risk of blockage from the source. Meanwhile, the rotation of the second threaded blade in the discharge pipe can simultaneously prevent the material from stagnating and congesting at the end of the conveying process. Therefore, the integrated design of single motor driving dual transmission links greatly simplifies the number of components, which not only reduces the equipment failure rate and maintenance costs, but also ensures the coordinated efficiency of the feeding and discharging links, providing a stable guarantee for production continuity.

[0014] 2. In this utility model, driven by the second servo motor, the stirring rod inside the mixing tank rotates, which efficiently and forcibly stirs the raw materials and additives. At the same time, the electric heating rod heats the materials, reducing the hardness of the plastic raw materials and enhancing their fusion effect with the additives. The flexible scraper continuously scrapes off the raw materials adhering to the tank wall, effectively preventing residue and clumping. In addition, the temperature sensor monitors the internal temperature in real time and feeds the data back to the PLC controller to achieve precise temperature control, avoiding raw material degradation or reduced mixing effect due to excessively high or uneven temperatures, thereby ensuring the stability of material properties and the consistency of finished product quality.

Under the transmission action of the synchronous belt 112, the first pulley 120 rotates accordingly, thereby driving the first threaded blade 116 to rotate in the feed pipe 109, smoothly pushing the raw material into the mixing tank 106. At the same time, the second pulley 117 also drives the first rotating rod 119 and the second threaded blade 118 to rotate synchronously in the discharge pipe 104, preparing for subsequent material conveying. In the auxiliary mechanism 3, by connecting the external pipe to the connecting pipe 302, the metering pump 301 can accurately deliver the additive to the mixing tank 106 according to the preset ratio. Subsequently, the second servo motor 108 drives the second rotating rod 115 to rotate, driving the stirring rod 114 and...

The temperature sensor 2 monitors the internal temperature of the mixing barrel 106 in real time and feeds the data back to the PLC controller 107 to achieve precise temperature control, ensure stable material performance, and avoid raw material degradation or poor mixing due to abnormal temperature. The evenly mixed materials enter the discharge pipe 104 under the control of the gear pump 105 and are conveyed to the injection head body 103 by the push of the second threaded blade 118, and finally injected into the mold cavity to complete the entire production process.
