[0002] With the widespread application of plastic products in various fields such as industry, agriculture, and daily life, the market demands increasingly higher quality from plastic products. Due to differences in usage scenarios and functional requirements, different plastic products require the precise mixing of various plastic granules with different properties.

[0003] In the production process of plastic products, the mixing of plastic granules is a crucial step. However, existing plastic granule mixing devices for plastic product manufacturing generally have a major shortcoming: the lack of a screening function for plastic granules. In actual production scenarios, impurities or excessively large plastic particles inevitably mix into the plastic granules. If these unsuitable substances enter the mixing stage, they will seriously affect the uniformity of the plastic granule mixing, thereby adversely affecting the molding, quality, and performance of subsequent plastic products, reducing production efficiency and product yield.

[0004] Therefore, it is necessary to provide a plastic pellet mixing device for the production of plastic products to solve the above-mentioned technical problems. Utility Model Content

The mixing tank 4 is fixedly installed between the two movable seats 3. The mixing tank 4 has a mixing mechanism inside it. The top side of the mixing tank 4 has a feed pipe 6 fixedly inserted. The bottom of the mixing tank 4 has a discharge pipe 13.

[0031] A screening box 7 is fixedly installed on the top of the feed pipe 6, and the screening box 7 is connected to the inside of the feed pipe 6. A filter screen 17 is installed inside the screening box 7.

[0032] A slotted plate 8 is fixedly installed on the front of a movable seat 3, and a mounting bracket 11 is fixedly installed on the front of a spiral guide rail 1. A second servo motor 10 is fixedly installed on the top of the mounting bracket 11. A rotating plate 9 is fixedly installed on the drive end of the second servo motor 10. A drive column 22 is fixedly installed on the back of the rotating plate 9, and the drive column 22 extends into the interior of the slotted plate 8, which can drive the movable seat 3 to move along a specific trajectory, thereby achieving the lateral shaking effect of the mixing tank 4 and improving the feeding efficiency and mixing quality.

[0033] In one embodiment, a slot 16 is provided on the back of the screening box 7, and the filter screen 17 is slidably inserted into the interior of the screening box 7 through the slot 16. A sealing plate 20 is fixedly installed on the back of the filter screen 17, and symmetrically distributed supports 19 are fixedly installed on the top of the sealing plate 20. The supports 19 are threadedly connected to wing bolts 21 through threaded holes. The back of the screening box 7 is provided with threaded grooves 18 corresponding to the position and number of supports 19, and the threaded grooves 18 are threadedly connected to the wing bolts 21, realizing the detachability of the filter screen 17 and facilitating its cleaning and replacement.

[0034] In one preferred embodiment, the stirring mechanism includes a stirring shaft 14 rotatably mounted inside the stirring tank 4, a plurality of stirring rollers 15 fixedly mounted on the outer wall of the stirring shaft 14, a first servo motor 5 fixedly mounted on the top of the stirring tank 4, and the drive end of the first servo motor 5 passes through the stirring tank 4 and extends into the interior of the stirring tank 4 and is fixedly connected to the top of the stirring shaft 14, thereby achieving the effect of mixing and stirring the plastic particles inside the stirring tank 4.

[0035] In one embodiment, symmetrically distributed diagonal braces are fixedly installed between the back of the slotted plate 8 and the top of a movable seat 3, which can enhance the stability of the slotted plate 8 and improve its structural strength.

[0036] In one preferred embodiment, support legs 12 are fixedly installed on both sides of the bottom of the mounting frame 11, which can increase the stability of the mounting frame 11 and ensure its load-bearing structure is stable.

[0037] In one embodiment, a manual valve is provided on the discharge pipe 13, which facilitates manual and flexible control of the start and stop of discharge and the flow rate. The operation is simple and can be adjusted as needed.

[0038] In one preferred embodiment, a sealing gasket is provided on the contact surface between the sealing plate 20 and the outer surface of the screening box 7 to enhance the sealing performance and prevent raw material leakage.

[0039] In one embodiment, the bottom end of the support leg 12 is flush with the bottom of the support frame 2, which makes the overall support of the device more stable, enhances stability, ensures safe operation, and reduces the risk of shaking and tilting.

[0040] The working principle of this invention is as follows: When using this device, the raw material plastic granules are first added through the top opening of the screening box 7. After the raw material enters the screening box 7, the filter screen 17 installed inside the screening box 7 will perform a screening operation on the raw material, effectively removing impurities and excessively large plastic particles. After screening, the qualified plastic granules are transported to the mixing tank 4 through the feed pipe 6. At the same time, the first servo motor 5 is started, and its drive end drives the stirring shaft 14 to rotate. The rotation of the stirring shaft 14 in turn drives the stirring roller 15 to rotate, and the stirring roller 15 stirs and mixes the plastic granules in the mixing tank 4. After the plastic granules are evenly mixed, the valve on the discharge pipe 13 is opened, and the mixed plastic granules are discharged from the device through the discharge pipe 13.

[0041] During device operation, the second servo motor 10 can be activated, its drive end driving the rotating plate 9 to rotate. The rotation of the rotating plate 9 causes the drive column 22 to rotate accordingly. The drive column 22 acts on the slotted plate 8, causing the slotted plate 8 to drive the movable seat 3 to move laterally back and forth on the guide rail 1, thereby realizing the lateral shaking of the mixing tank 4. This shaking is transmitted to the screening box 7 through the feed pipe 6. During the raw material addition stage, it can enhance the screening efficiency of the filter screen plate 17 in the screening box 7 and improve the raw material addition efficiency. When the raw materials are mixed in the mixing tank 4, the shaking of the mixing tank 4 can make the plastic particles mix more evenly, thereby improving the quality of the plastic products.

[0042] During operation, the filter screen 17 intercepts and filters out impurities and large plastic particles. To ensure its filtration effect, these intercepted materials need to be cleaned regularly. When the device is not in operation, the operator can directly unscrew the wing bolt 21 on the support 19 to unscrew it from the threaded groove 18, and then pull the filter screen 17 out of the slot 16 through the sealing plate 20, thus removing the filter screen 17 from the screening box 7. This detachable design not only facilitates the cleaning of impurities and large plastic particles intercepted on the filter screen 17, but also allows for convenient and quick replacement of filter screens 17 of different specifications according to different production needs of plastic products.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
