Description

Technical Field

[0001] This utility model relates to the field of plastic granule processing technology, and in particular to a portable plastic granule mixing device. Background Technology

[0002] In the production process of plastic products, in order to obtain a final product with a specific color, performance or function, it is usually necessary to fully mix the base plastic granules with a variety of additives such as color masterbatch, antistatic agent, flame retardant, and filler in a precise ratio. The uniformity of mixing directly determines the quality stability and consistency of the final product. Therefore, an efficient and precise mixing device is an indispensable key equipment in the plastic processing production line. In the plastics processing industry, in order to improve the performance of plastic products, such as giving them antistatic properties, it is usually necessary to add additives such as antistatic agents to plastic granules in proportion. This process is usually completed in a mixing device.

[0003] In some existing technologies, traditional mixing devices rely heavily on manual experience or simple measuring tools to estimate the amount of additives added. This crude method makes it difficult to accurately control the amount of additives added, resulting in inconsistent amounts. When the amount added is insufficient, the expected antistatic effect cannot be achieved, affecting product quality. When the amount added is excessive, it will cause serious waste of additives, increase production costs, and may even negatively affect the properties of the plastic matrix due to excessive additives. There is a lack of structures that can quantitatively add antistatic agents. Utility Model Content

[0004] The main objective of this invention is to provide a portable plastic granule mixing device that effectively solves the problem of traditional mixing devices relying on manual experience or simple measuring tools for additive addition. This crude method makes it difficult to accurately control the amount of additives added, resulting in inconsistent amounts. Insufficient addition fails to achieve the desired antistatic effect, affecting product quality, while excessive addition leads to serious waste of additives, increases production costs, and may even negatively impact the properties of the plastic matrix. Furthermore, the invention lacks a structure that allows for the quantitative addition of antistatic agents.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A portable plastic granule mixing device includes a mixing tank, a precision feeding mechanism installed on the top of the mixing tank, a protective tarpaulin installed on the top of the precision feeding mechanism, a storage tank installed on the top of the protective tarpaulin, and a feeding assembly installed on the inner surface of the mixing tank.

[0006] Preferably, a support frame one is installed on the outer surface of the storage tank, and a support frame two is symmetrically installed on the bottom of the mixing tank. The bottom of the support frame one and the two support frames two are jointly installed with a base plate.

[0007] Preferably, the precision feeding mechanism includes a feeding hopper, and bearing seats are symmetrically installed on the upper side of the inner surface of the feeding hopper. The inner surfaces of the two bearing seats are rotatably connected to a rotating shaft.

[0008] Preferably, a disc is mounted on the opposite ends of the two rotating shafts, a weighing platform is mounted on the top of the disc, and a drive box is mounted on the rear end of the rotating shaft.

[0009] Preferably, a support frame is provided at the bottom of the drive box, and the support frame is installed on the rear side of the top of the mixing tank.

[0010] Preferably, the feeding assembly includes a tray, which is installed on the lower side of the inner surface of the mixing tank. A bearing seat two is installed in the middle of the inner surface of the tray, and a rotating shaft two is rotatably connected to the inner surface of the bearing seat two. A drive box is installed at the bottom of the rotating shaft two.

[0011] Preferably, a scraper is installed on the lower side of the outer surface of the second rotating shaft, a stirring blade is installed on the upper middle side of the outer surface of the second rotating shaft, a material discharge channel is installed on the rear side of the bottom of the tray, a groove is provided on the rear side of the inner surface of the tray, a door panel is slidably connected to the inner surface of the groove, and the door panel is located at the top of the material discharge channel.

[0012] Preferably, a fixing plate is installed on the left end of the door panel, an electric telescopic rod is installed on the upper side of the right end of the fixing plate, a control box is installed on the right end of the electric telescopic rod, and the control box is installed on the lower left side of the outer surface of the mixing tank.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This device features a precisely designed feeding mechanism that allows for the quantitative addition of antistatic agent to the plastic mixture based on the amount of material inside the mixing tank. This avoids a series of problems that occur during mixing of plastic granules, such as inaccurate addition of antistatic agent, unstable effects, and significant waste. By adding the antistatic agent during mixing, static electricity can be discharged in a timely manner, reducing the risk of electrostatic discharge and significantly improving the safety of the production process. Furthermore, the precise feeding mechanism uses a closed conveyor system to deliver the additive directly into the mixing tank. The entire process is isolated from the external environment, effectively preventing the leakage and volatilization of the additive, protecting the health of operators, improving the working environment, and eliminating potential safety hazards.

[0014] 2. This device features a designed feeding component with a scraper installed at the lower end of the rotating shaft. Combined with the automatic opening and closing mechanism at the door panel, this component effectively scrapes out all remaining material from the bottom and discharges it through the feeding channel. The feeding process can be completed without manual intervention. This automated design not only reduces the labor intensity of operators but also minimizes human error, improves production efficiency and equipment intelligence. Furthermore, because the scraper thoroughly removes material from the bottom, it reduces material adhesion to the inner wall or bottom of the equipment, thus reducing the difficulty and frequency of subsequent cleaning work.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Example 1, as Figure 1 As shown, a portable plastic granule mixing device includes a mixing tank 1, a precision feeding mechanism 3 installed on the top of the mixing tank 1, a protective tarpaulin 4 installed on the top of the precision feeding mechanism 3, a storage tank 2 installed on the top of the protective tarpaulin 4, and a feeding component 5 installed on the inner surface of the mixing tank 1.

[0019] In this embodiment, the precise feeding mechanism 3 is used to add the antistatic additive quantitatively and in a closed manner, and the feeding component 5 is used to achieve full mixing and automatic feeding of the material without residue. The operator adds the plastic granules to be mixed into the mixing tank 1 by opening the top cover of the mixing tank 1. The protective cloth 4 is made of flexible material. As the top cover of the mixing tank 1 is flipped open, the precise feeding mechanism 3 rotates with the top cover. The protective cloth 4 deforms in this process to adapt to the displacement of the precise feeding mechanism 3. Then, the top cover is closed, and the antistatic agent is precisely metered through the precision feeding mechanism 3 and added into the mixing tank 1. Then, it is mixed into the plastic material under the action of the feeding component 5.

[0020] For details, please refer to Figure 1 and Figure 2 In this embodiment, a support frame 6 is installed on the outer surface of the storage tank 2, and a support frame 7 is symmetrically installed on the bottom of the mixing tank 1. The bottom of the support frame 6 and the two support frames 7 are together installed with a base plate 8. Further reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the precision feeding mechanism 3 includes a feeding hopper 301. Bearing seats 302 are symmetrically installed on the upper side of the inner surface of the feeding hopper 301. The inner surfaces of the two bearing seats 302 are rotatably connected to the rotating shafts 303. The opposite ends of the two rotating shafts 303 are jointly installed with a disc 304. A weighing platform 305 is installed on the top of the disc 304. A drive box 306 is installed at the rear end of the rotating shaft 303. A support frame 307 is provided at the bottom of the drive box 306. The support frame 307 is installed on the rear side of the top of the mixing tank 1. Based on the weight of the main material in mixing tank 1 and the preset mixing ratio, the operator sets the target weight of the additive to be added. When the preparation is complete, the antistatic agent to be added is added into the storage tank 2. The electric valve at the bottom of the storage tank 2 is linked with the controller inside the drive box 306 and the controller of the weighing platform 305. The weighing platform 305 presets the required weight of antistatic agent. When the weighing platform 305 measures a sufficient amount, the valve of the storage tank 2 automatically closes, and the drive box 306 drives the rear rotating shaft 303 to rotate, pouring the material at the top of the weighing platform 305 into the mixing tank 1. While the weighing platform 305 is continuously unloading material, the displayed weight will decrease in real time. When the weight decreases to the preset zero value or reaches the target addition amount, it indicates that the addition is completed. At this time, the control system controls the motor of the drive box 306 to reverse, driving the rotating shaft 303 and the disc 304 to return to the initial horizontal position, preparing for the next addition. The precision feeding mechanism 3 allows for the quantitative addition of antistatic agent to the plastic based on the amount of material inside the mixing tank 1. This avoids a series of problems that occur during the mixing of plastic granules in the mixing tank 1, such as inaccurate addition of antistatic agent, unstable effect, and serious waste. By adding antistatic agent during mixing, static electricity can be discharged in time, reducing the risk of electrostatic discharge and significantly improving the safety of the production process. Furthermore, the precision feeding mechanism 3 uses a closed conveyor system to directly deliver the additive into the mixing tank. The entire process is isolated from the external environment, effectively preventing the leakage and volatilization of the additive, protecting the health of operators, improving the working environment, and eliminating potential safety hazards.

[0021] Example 2: Based on Example 1, this example adds a feeding component 5 for stirring, mixing, and conveniently discharging the material inside the mixing tank 1. By setting the feeding component 5, a scraper 504 is installed at the lower end of the rotating shaft 503. Combined with the automatic opening and closing effect at the door panel 508, all the material left at the bottom is scraped out and discharged through the feeding channel 506 during the feeding process, and the feeding process can be completed without manual intervention.

[0022] For details, please refer to Figure 1 , Figure 4 and Figure 5 In this embodiment, the feeding assembly 5 includes a tray 501, which is installed on the lower side of the inner surface of the mixing tank 1. A bearing seat 502 is installed in the middle of the inner surface of the tray 501. A rotating shaft 503 is rotatably connected to the inner surface of the bearing seat 502. A drive box 512 is installed at the bottom of the rotating shaft 503. Further reference Figure 1 , Figure 4 and Figure 5 In this embodiment, a scraper 504 is installed on the lower side of the outer surface of the second rotating shaft 503, a stirring blade 505 is installed on the upper middle side of the outer surface of the second rotating shaft 503, a feeding channel 506 is installed on the rear side of the bottom of the tray 501, a groove 507 is provided on the rear side of the inner surface of the tray 501, a door panel 508 is slidably connected to the inner surface of the groove 507, and the door panel 508 is located at the top of the feeding channel 506. Further reference Figure 1 , Figure 4 and Figure 5 In this embodiment, a fixing plate 509 is installed on the left end of the door panel 508, an electric telescopic rod 510 is installed on the upper side of the right end of the fixing plate 509, a control box 511 is installed on the right end of the electric telescopic rod 510, and the control box 511 is installed on the lower side of the left side of the outer surface of the mixing tank 1. After the additives are added, the drive box 512 of the feeding component 5 is started. The drive motor inside the drive box 512 starts to work, driving the rotating shaft 503 to rotate under the support of the bearing seat 502. During the rotation, the rotating shaft 503 drives the stirring blades 505 on its outer surface to tumble, cut and sprinkle the plastic particles and antistatic agent in the mixing tank 1 at high speed, so that the two reach a uniform mixing state in a short time. After the mixing is completed, the drive box 512 is stopped. At this time, the material naturally accumulates on the tray 501 at the bottom of the mixing tank 1 under the action of gravity. The inlet of the discharge channel 506 is blocked by the door panel 508, and the material cannot be discharged. The operator starts the control box 511. The control box 511 issues a command to drive the electric telescopic rod 510 to extend to the left. The electric telescopic rod 510 drives the fixed plate 509 and the door panel 508 connected to it to slide to the left along the slide 507, thereby opening the inlet of the discharge channel 506. At the same time, the drive box 512 is restarted to drive the rotating shaft 503 to rotate. The scraper 504 installed at the bottom of the rotating shaft 503 rotates accordingly, forcibly scraping and pushing the material accumulated on the pallet 501, especially the material adhering to the bottom and corners, into the opened discharge channel 506 to complete the discharge. When the scraper 504 rotates, its edge is in close contact with the surface of the pallet 501 or maintains a very small gap, which can thoroughly "sweep" the material at the bottom. In conjunction with the automatic opening and closing of the door panel 508, the material is "forced to be emptied". After observing that the material has been discharged, the operator controls the electric telescopic rod 510 to retract through the control box 511, pushes the door panel 508 to slide to the right until the material discharge channel 506 is closed again, and completes the entire material discharge process. The designed feeding component 5 has a scraper 504 installed at the lower end of the rotating shaft 503. Combined with the automatic opening and closing effect at the door panel 508, all the material left at the bottom is scraped out and discharged through the feeding channel 506 during feeding. The feeding process can be completed without manual intervention. This automated design not only reduces the labor intensity of operators but also reduces human error, improves production efficiency and equipment intelligence. Furthermore, since the scraper 504 can thoroughly remove the material at the bottom, it reduces the adhesion of material to the inner wall or bottom of the equipment, reducing the difficulty and frequency of subsequent cleaning work.
