[0002] Household appliances mainly refer to various electrical and electronic appliances used in homes and similar places, also known as civil appliances or daily appliances. Household appliances have created a more comfortable and beautiful living and working environment that is more conducive to physical and mental health, and have provided a wealth of cultural and entertainment options, becoming necessities for modern family life. To meet the demand for lightweight home appliances, a large number of plastic parts are used in home appliance components. Before the plastic parts are molded, they need to be treated with a dehumidifying dryer to remove the moisture from the plastic granules. Currently, in traditional dehumidification dryers, plastic granules are mostly concentrated in one chamber, and dehumidification is achieved by heating the chamber. However, the accumulation of plastic granules makes it difficult to remove the dried granules in a timely manner, and it is difficult for subsequent undried plastic granules to enter the chamber, which greatly affects the continuity of plastic granule dehumidification.

[0003] To address these issues, we propose a dehumidifying dryer for processing and molding plastic parts for household appliances. Utility Model Content

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-5As shown, it illustrates a dehumidifying dryer for processing and molding plastic parts for household appliances according to one embodiment of the present invention. In some examples, including: The base plate 1 has two upright plates 2 fixedly connected to its top ends. Multiple retainers 3 are fixedly connected between the top ends of the two upright plates 2. A straight groove 4 is provided on one side of the upright plate 2. The dehumidifier cylinder 5 is fixedly connected between multiple retainers 3. The bottom end of the dehumidifier cylinder 5 has an opening. The dehumidifier cylinder 5 is equipped with a dehumidifier component 6, which is used to work with the dehumidifier cylinder 5 to remove moisture from the plastic particles. The receiving component 7 is assembled between the two vertical plates 2 and is used to receive the plastic particles discharged from the dehumidification cylinder 5.

[0024] For example, such as Figure 1 As shown, a feedback window is provided on the outside of the dehumidifier cylinder 5, and an observation plate is fixedly connected inside the feedback window.

[0025] More specifically, the feedback window allows personnel to observe the internal state of the dehumidifier cylinder 5. For example, such as Figure 3 As shown, the dehumidification assembly 6 includes a heating cylinder 8, which is vertically fixedly connected to the middle of the inner side of the dehumidification cylinder 5. An electric heating wire 9 is fixedly connected inside the heating cylinder 8, and a guide plate 10 is fixedly connected to the outer side of the heating cylinder 8.

[0026] Furthermore, a feeding pipe is provided at the top of the dehumidification cylinder 5. Through the feeding pipe, the plastic granules to be dried can be concentrated and sent into the dehumidification cylinder 5 and received by the guide plate 10. For example, such as Figure 3 As shown, the guide plate 10 is spiral-shaped, and multiple stabilizing seats are provided on the outer side of the guide plate 10. The end of the stabilizing seat near the inner wall of the dehumidification cylinder 5 is also fixedly connected to the inner wall of the dehumidification cylinder 5.

[0027] More specifically, the spiral shape of the guide plate 10 can improve the path of the plastic particles at the guide plate 10 and increase the heating time of the plastic particles. Furthermore, in order to ensure the thermal conductivity of the guide plate 10, the guide plate 10 can be made of copper alloy. Furthermore, with the addition of a stabilizing base, the inner wall of the dehumidifying cylinder 5 can provide auxiliary support for the guide plate 10, greatly ensuring the stability of the guide plate 10 in application. like Figures 3-5 As shown, this illustrates a dehumidifying dryer for processing and molding plastic parts for household appliances, according to another embodiment of the present invention. The receiving component 7 includes: Two displacement frames 11 are slidably connected inside two linear slide grooves 4 respectively. A support plate 12 is fixedly connected between the two displacement frames 11. A linkage plate 13 is rotatably connected to the bottom of the displacement frame 11 at the end away from the support plate 12. The transmission box 14 is fixedly connected to the top of the base plate 1. The top of the transmission box 14 is rotatably connected to the transmission shaft 15. Both ends of the transmission shaft 15 are fixedly connected to the eccentric plates 16, and the ends of the two linkage plates 13 away from the displacement frame 11 are respectively rotatably connected to one end of the two eccentric plates 16. The drive motor 17 is fixedly connected to one side of the top of the transmission box 14. The output end of the drive motor 17 is fixedly connected to the drive spur gear 18. The middle part of the transmission shaft 15 is fixedly connected to the reduction spur gear 19, and the reduction spur gear 19 is meshed with the drive spur gear 18. For example, such as Figure 4 As shown, a linear guide rod is fixedly connected inside the linear slide 4, and a limit hole is opened at the top of the displacement frame 11, and the limit hole and the linear guide rod are in clearance fit.

[0028] More specifically, the linear guide rod and the limiting hole can guide the displacement of the displacement frame 11, prevent the displacement frame 11 from undergoing uncontrollable displacement, and greatly ensure the stability of the displacement of the displacement frame 11. For example, such as Figure 4 As shown, the end of the receiving plate 12 away from the dehumidifying cylinder 5 is inclined downward, and the receiving plate 12 is funnel-shaped.

[0029] More specifically, by utilizing the inclined characteristics of the receiving plate 12, when the plastic particles in the dehumidification cylinder 5 reach the receiving plate 12, the plastic particles can flow along the inclined direction of the receiving plate 12 until the plastic particles are sent to the end of the receiving plate 12. Furthermore, to prevent plastic particles from falling off the edge when flowing at the receiving plate 12, a baffle is fixedly connected to the edge of the receiving plate 12. Furthermore, due to the structural characteristics of the receiving plate 12, plastic granules can be collected at the end of the receiving plate 12 to facilitate the storage and packaging of plastic granules. For example, such as Figure 4 As shown, the bottom end of the displacement frame 11 away from the receiving plate 12 and the end of the eccentric plate 16 away from the transmission shaft 15 are both provided with rotating shafts, and the two ends of the linkage plate 13 are respectively connected to the two corresponding rotating shafts. More specifically, by setting the rotating shaft, the two ends of the linkage plate 13 can be stably assembled, ensuring the stability and smoothness of the rotation of the linkage plate 13 between the displacement frame 11 and the eccentric plate 16.

[0030] Working principle: First, the electric heating wire 9 is activated. The heat generated by the electric heating wire 9 is transferred to the guide plate 10 through the heating cylinder 8, causing the surface of the guide plate 10 to heat up. Then, the plastic granules to be dried are poured into the dehumidification cylinder 5 and received by the guide plate 10. With the structural characteristics of the guide plate 10, the plastic granules can flow along the dehumidification cylinder 5. Since the guide plate 10 is heated, the moisture in the plastic granules can be removed by the guide plate 10 during the flow of the plastic granules, thus achieving dehumidification and drying of the plastic granules. The dried plastic granules are received by the receiving plate 12. Then, the drive motor 17 is started to cause the drive spur gear 18 to move the reduction spur gear 19, which in turn drives the eccentric plate 16 to rotate through the drive shaft 15. Since the eccentric plate 16 is connected between the displacement frame 11 and the linkage plate 13, when the eccentric plate 16 rotates, it can drive the receiving plate 12 to move back and forth with the help of the linkage plate 13 and the displacement frame 11, causing the receiving plate 12 to vibrate. This allows the plastic granules received by the receiving plate 12 to be delivered to the end of the receiving plate 12 more smoothly.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
