Description

Technical Field

[0001] This utility model relates to the field of antibacterial masterbatch production equipment, and in particular to a rotary drying device for antibacterial masterbatch. Background Technology

[0002] In the production of antimicrobial masterbatches, drying is a crucial step in removing moisture from materials and ensuring product performance. With the expanding applications of antimicrobial materials (such as in medical and health, food packaging, and textiles), higher demands are being placed on the efficiency, uniformity, and ease of use of masterbatch drying equipment. Highly efficient drying devices not only improve production efficiency but also ensure the stability of the antimicrobial activity and physical properties of the masterbatch. Therefore, developing rotary drying devices that combine automated stirring with precise temperature control has become an important direction for industry upgrading.

[0003] Traditional antibacterial masterbatch drying equipment mostly employs a static drying mode, where materials accumulate in the drying trays and are heated only from the bottom or sides. This results in low heat transfer efficiency and long drying times. For example, during static drying, the upper and lower layers of masterbatch are heated unevenly, with the bottom layer prone to overheating and damaging the antibacterial components, while the upper layer may not be thoroughly dried, affecting product quality consistency. Furthermore, the traditional method of fixing the drying trays is cumbersome, requiring bolts or clips to secure them one by one. This is time-consuming to install and remove, and improper operation can easily cause equipment shaking, increasing safety hazards. Simultaneously, the lack of a dynamic stirring mechanism fails to effectively disperse the accumulated masterbatch, further exacerbating the problem of uneven drying. The shortcomings of existing technologies—low drying efficiency, poor uniformity, and complex operation—are no longer sufficient to meet the demands of modern large-scale, high-quality antibacterial masterbatch production, necessitating structural innovation to optimize the drying process. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary drying device for antibacterial masterbatch, which aims to solve the problems of low drying efficiency, uneven heating, and cumbersome loading and unloading in existing antibacterial masterbatch drying devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rotary drying device for antibacterial masterbatch includes a shell, a motor mounted on the top side of the inner wall of the shell, a rotating rod fixedly connected to the drive end of the motor, a fixing component provided on the bottom side of the rotating rod, an installation groove opened in the middle of the inner wall of the shell, a drying component disposed inside the installation groove, a fan mounted on the bottom side of the inner wall of the shell, a ring door connected to the left front end of the shell via a rotating shaft, and the right end of the ring door connected to the right front end of the shell via a buckle.

[0007] Furthermore, the fixing component includes a knob, the top side of which is rotatably connected to the bottom side of the rotating rod, a low rod rotatably connected to the bottom side of the knob, a screw threadedly connected to the inside of the knob, and a splined shaft fixedly connected to the bottom side of the screw.

[0008] Furthermore, a groove is provided on the bottom side of the rotating rod, a splined through groove is provided on the bottom side of the low rod, the top end of the screw is located inside the groove, and the splined shaft is located inside the splined through groove.

[0009] Furthermore, a connector is fixedly connected to the bottom end of the rear side of the rotating rod, and the bottom end of the front side of the connector is fixedly connected to the top end of the rear side of the low rod.

[0010] Furthermore, the drying assembly includes a drying tray with multiple through holes inside, a heating ring inside each through hole, and a spline groove at the middle of the top side of the drying tray.

[0011] Furthermore, stirring rods are fixedly connected to the middle of both sides of the inner wall of the outer shell, and the bottom side of the stirring rods abuts against the top side of the drying tray.

[0012] Furthermore, a handle is fixedly connected to the right end of the front side of the ring gate.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the ring door can be easily opened by opening the buckle and pulling the handle. After placing the drying tray in, turning the knob moves the screw and spline shaft downward, allowing the spline shaft to engage with the spline groove and precisely fix the drying tray. This design simplifies the loading and unloading process, avoids the cumbersome operation of traditional bolt fixing, and ensures that the drying tray is stable and does not wobble during rotation through mechanical engagement, providing a reliable foundation for efficient drying and improving the ease of use and stability of the equipment.

[0015] 2. In this invention, a motor drives a rotating rod, splined shaft, and drying disc to rotate, while simultaneously causing a stirring rod to agitate the antibacterial masterbatch. With the combined action of the heating ring and fan, the rotation and stirring ensure that the masterbatch is evenly exposed to the hot airflow at all angles, overcoming the limitations of traditional static drying and effectively avoiding uneven drying or low efficiency caused by localized accumulation. This dynamic drying mode significantly improves heat transfer efficiency, shortens drying time, and ensures that each masterbatch reaches the ideal degree of dryness, thus improving product quality consistency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a rotary drying device for antibacterial masterbatch, comprising a shell 1, a motor 13 mounted on the top side of the inner wall of the shell 1, a rotating rod 12 fixedly connected to the drive end of the motor 13, a knob 11 provided on the bottom side of the rotating rod 12, an installation groove provided in the middle of the inner wall of the shell 1, a drying tray 9 provided inside the installation groove, a fan 8 mounted on the bottom side of the inner wall of the shell 1, a ring door 2 connected to the left front end of the shell 1 via a rotating shaft 5, and the right end of the ring door 2 connected to the right front end of the shell 1 via a buckle 4. The top side of the knob 11 is connected to the rotating rod 12. The bottom side of rod 12 is rotatably connected to the bottom side of knob 11, and a low rod 10 is rotatably connected to the bottom side of knob 11. A screw 16 is threadedly connected to the inside of knob 11, and a spline shaft 17 is fixedly connected to the bottom side of screw 16. A groove is opened on the bottom side of rod 12, and a spline through groove is opened on the bottom side of low rod 10. The top of screw 16 is located inside the groove, and spline shaft 17 is located inside the spline through groove. A connector 14 is fixedly connected to the bottom rear side of rod 12. The bottom front side of connector 14 is fixedly connected to the top rear side of low rod 10. A handle 3 is fixedly connected to the right front side of ring door 2.

[0024] Specifically, the operation process for using this antibacterial masterbatch rotary dryer is designed around the needs of efficient drying and convenient maintenance. First, open the latch 4 to release the limit on the ring door 2, pull the handle 3 to open the ring door 2, and place the drying tray 9 into the mounting slot. Turn the knob 11. Since the screw 16 is threadedly connected to the knob 11 and fixed to the spline shaft 17, the spline shaft 17 is located in the spline groove. The rotation of the knob drives the screw and spline shaft to move downward, so that the spline shaft 17 is embedded in the spline groove 15, completing the positioning and fixing of the drying tray.

[0025] Reference Figure 1 and Figure 2 The drying tray 9 has multiple through holes 7 inside, and a heating ring is installed inside the through holes 7. A spline groove 15 is provided at the middle of the top side of the drying tray 9. Stirring rods 6 are fixedly connected to the middle of the left and right sides of the inner wall of the outer shell 1. The bottom side of the stirring rods 6 abuts against the top side of the drying tray 9.

[0026] Specifically, the antibacterial masterbatch to be dried is then placed on the surface of the drying tray 9, and the ring door 2 is closed and repositioned using the latches. The heating ring, fan 8, and motor 13 are then activated. The heating ring and fan work together to dry the masterbatch, while the motor 13 drives the rotating rod 12 to rotate the spline shaft 17, the drying tray 9, and the masterbatch. During rotation, the stirring rod 6 continuously tumbles the masterbatch on top of the drying tray, ensuring that the masterbatch is heated evenly from all angles, avoiding localized overheating or insufficient drying, and significantly improving drying efficiency and effect. The entire operation achieves precise positioning and dynamic stirring through mechanical linkage, ensuring the uniformity and efficiency of the antibacterial masterbatch drying.

[0027] Working principle: In use, first open the buckle 4 to release the limit on the ring door 2, then pull the handle 3 to open the ring door 2, and then place the drying tray 9 into the installation slot. Then turn the knob 11. Since the screw 16 is threadedly connected to the knob 11 and fixedly connected to the spline shaft 17, and the spline shaft 17 is located inside the spline groove, turning the knob 11 will drive the screw 16 and the spline shaft 17 to move downward, so that the spline shaft 17 enters the spline groove 15. Then place the antibacterial masterbatch to be dried on the drying tray 9, and then close the ring door 2 again and limit it. Then start the heating ring, fan 8 and motor 13. The masterbatch is dried by the heating ring and fan 8. After starting the motor 13, the motor 13 will drive the rotating rod 12 to drive the spline shaft 17 and the drying tray 9 to rotate, and at the same time drive the masterbatch to rotate. While rotating, the stirring rod 6 will stir the masterbatch on the top side of the drying tray 9, so that the masterbatch is dried from all angles, thereby improving the drying effect.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
