Description

Technical Field

[0001] The invention belongs to the technical field of dehumidification devices, and in particular relates to a plastic particle dehumidification device. Background Art

[0002] In the production process of plastic products, plastic pellets are important raw materials, and their water content has a direct impact on the quality and performance of the final product. Excessive water content will cause defects such as bubbles and cracks in the plastic products during the molding process, which will in turn affect the mechanical strength and appearance quality of the product. Therefore, effective dehumidification treatment before the plastic pellets enter the molding machine is one of the essential steps. Existing plastic pellet dehumidification devices usually use a combination of heating and stirring to remove moisture from the pellets.

[0003] In the prior art (publication number CN218504959U, patent name is a patent application for a plastic particle dehumidifier), it includes a housing, a stirring mechanism, a storage tray, and an electric heating wire installed inside the storage tray. The interior of the storage tray is a stirring chamber. The stirring mechanism includes a driving motor and a rotating table. The surface of the housing is equipped with a heat dissipation component for cooling the plastic particles. The stirring plate is driven to rotate by the rotating table. The plastic particles are stirred to accelerate the dehumidification process and prevent the plastic particles from melting due to overheating. In the process of implementing this technical solution, it is found that there are at least the following problems in the prior art.

[0004] In the above patent, the dehumidification device has certain limitations, especially in the design of the stirring mechanism. The dehumidification device uses a stirring shaft that rotates in a single direction to mix the plastic particles. Although this unidirectional rotation method can achieve a certain degree of particle tumbling, it is not effective in promoting uniform heating of the particles. Due to the uneven distribution of particles, the particles close to the heating element may be over-dried or even burnt, thus affecting the overall dehumidification efficiency and quality. Summary of the invention

[0005] The present application aims to solve at least one of the technical problems of uneven stirring and heating of dehumidification devices in the prior art. To this end, the present application proposes a plastic particle dehumidification device.

[0006] To achieve the above-mentioned purpose, the specific technical scheme of the present invention is as follows: a plastic particle dehumidification device, comprising a bottom shell and an upper cover covering the bottom shell, a rotatable stirring shaft is penetrated through one side of the outer surface of the bottom shell, and inner gear rings coaxially and inversely rotated with the stirring shaft are provided at both ends of the inside of the bottom shell, and stirring blades are equidistantly distributed between the outer surfaces of the two inner gear rings.

[0007] Preferably, a butt joint pipe is fixed to the upper part of the upper cover, and the top opening of the butt joint pipe is communicated with the interior of the upper cover, and a heater is also arranged at the opening above the upper cover.

[0008] Preferably, one end of one side of the stirring shaft is fixedly connected to gear one, and gear two is meshedly connected to the upper and lower outer circumferential surfaces of gear one, and an inner gear ring is also meshed on the outer circumferential surface of gear two, and the surface of the stirring blade contacts the inside of the bottom shell.

[0009] Preferably, a circulation hole is formed through one side of the outer surface of the gear 2, and a fan blade for extracting airflow is fixed inside the circulation hole.

[0010] Preferably, a circulation pipe is connected to the other opening of the circulation hole, and a circulation cover is covered above the heater, and one end of the circulation pipe is connected to one side of the outer surface of the circulation cover and communicated with the interior thereof.

[0011] Preferably, a pulley 1 is fixed on one side of the outer circumference of the stirring shaft, and a rotatable shaft 1 is provided above the upper cover, a pulley 2 is fixed at one end of the shaft parallel to the pulley 1, and a belt 1 is also sleeved between the pulleys 1 and 2.

[0012] Preferably, a crown gear is fixed to one end of the rotating shaft, and a gear three is meshingly connected to one side of the crown gear, so that the gear three can rotate together with the crown gear.

[0013] Preferably, a pulley three capable of rotating therewith is fixed below the gear three, and a rotating shaft two is arranged between the bottom surface of the pulley three and the top of the upper cover.

[0014] Preferably, a rotatable impeller is provided at the opening of the docking tube, and only a pulley four extends upward from the top of the impeller, and power is transmitted between the pulley four and the pulley three through the belt two.

[0015] Preferably, the upper cover and the bottom shell are fixedly connected via fasteners, and a bracket is fixedly connected to the bottom surface of the bottom shell.

[0016] The plastic particle dehumidification device of the present invention has the following advantages:

[0017] 1. This plastic particle dehumidification device, when dehumidifying the plastic particles in the bottom shell, first put the particles in the bottom shell and cover it with a lid. Then start the heater and the stirring shaft to heat the particles evenly. When the stirring shaft rotates, the gear 1 drives the gear 2, which in turn drives the inner gear ring to rotate in the opposite direction, so that the stirring blades also rotate in the opposite direction, thereby ensuring that the particles are heated and dehumidified more evenly.

[0018] 2. In this plastic particle dehumidification device, when gear 1 drives gear 2 meshing with it, the rotation of gear 2 drives the fan blades thereon to rotate. When the fan blades rotate, they draw airflow inside the bottom shell, which flows through the circulation pipe and is reheated by the heater, forming a circulation heating process, which helps to improve the dehumidification efficiency of the plastic particles inside the bottom shell.

[0019] 3. A plastic particle dehumidification device, when the stirring shaft rotates, it drives pulley 1 to rotate. Pulley 1 drives pulley 2 located on one side of the upper cover through belt 1. When pulley 2 rotates, it drives gear 3 meshing with it through the crown gear at one end of it. After gear 3 rotates, it drives the impeller inside the docking tube through belt 2. The rotation of the impeller can effectively transfer the heat generated by the upper heater to the inside of the bottom shell, thereby helping to effectively dehumidify the plastic particles inside the bottom shell.

DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] like Figure 1-Figure 2 As shown, a plastic particle dehumidification device of the present invention includes a bottom shell 11 for drying and dehumidification, the bottom shell 11 is a top opening structure, which is used to add plastic particles inside, and the upper opening of the bottom shell 11 is covered with an upper cover 12, and the connection between the upper cover 12 and the bottom shell 11 is fixedly connected by a fastener 13. At the same time, a rotatable stirring shaft 21 is penetrated from one side of the outer surface of the bottom shell 11, and as the stirring shaft 21 rotates, the material inside the bottom shell 11 can be stirred and turned. The rotation of the stirring shaft 21 is driven by the output of the motor 2, and the output end of the motor 2 is connected to one end of the stirring shaft 21. The overall dehumidification device is supported and fixed by a bracket 1 fixedly connected to the bottom surface of the bottom shell 11. A butt-joint pipe 121 is fixed on the upper part of the upper cover 12, and the top opening of the butt-joint pipe 121 is communicated with the inside of the upper cover 12, and a heater 4 is also provided at the upper opening of the upper cover 12, through which heat can be transferred to the bottom shell 11. Baffles 14 are fixed to both ends of the bottom shell 11 .

[0033] like Figure 2-Figure 6As shown, a gear 1 22 is fixedly connected to one end of the stirring shaft 21, and the gear 1 22 can rotate with the stirring shaft 21. At the same time, the outer circumference of the gear 1 22 is respectively meshed with a gear 2 23, and the outer circumference of the gear 2 23 is also meshed with an inner gear ring 5, and a stirring blade 51 is fixed between the two inner gear rings 5. And the surface of the stirring blade 51 is against the inside of the bottom shell 11. Therefore, when the plastic particles inside the bottom shell 11 need to be dehumidified, the particles are placed inside the bottom shell 11, and the upper cover 12 is covered on the bottom shell 11, and then the heater 4 and the stirring shaft 21 are turned on, so that the particles inside the bottom shell 11 can be evenly heated and dehumidified. As the stirring shaft 21 rotates, the gear 1 22 provided at one end of the stirring shaft 21 can drive the gear 2 23, and after the gear 2 23 rotates, the inner gear ring 5 can be driven in the reverse direction. After the inner gear ring 5 rotates in the reverse direction, the stirring blade 51 can rotate in the reverse direction together, which can further improve the uniform heating of the particles.

[0034] like Figure 6-Figure 8 As shown, a circulation hole 231 is provided on one side of the outer surface of the gear 23, and a fan blade 232 for extracting airflow is fixed inside the circulation hole 231, and a circulation pipe 3 is docked at the other end opening of the circulation hole 231, through which the airflow inside the bottom shell 11 can be circulated. A circulation cover 31 is also covered above the heater 4, and one end of the circulation pipe 3 is connected to one side of the outer surface of the circulation cover 31 and communicates with its interior. Therefore, when the gear 1 22 drives the gear 2 23 meshing above, the rotation of the gear 2 23 can make the fan blade 232 rotate together, and the airflow inside the bottom shell 11 is sucked after the fan blade 232 rotates, and then the airflow passes through the circulation pipe 3 and is heated by the heater 4 again, so that the circulation heating can be achieved.

[0035] like Figure 3 and Fig. 9 As shown, a pulley 24 is fixed on the other side of the outer circumference of the stirring shaft 21, and a rotatable shaft 251 is arranged on the upper side of the upper cover 12, and a pulley 25 is fixed on one end of the shaft 251 parallel to the pulley 24, and a belt 241 is also sleeved between the pulley 24 and the pulley 25, and the belt 241 can be removed from the pulley 24 and the pulley 25, and a crown gear 252 is fixed on the other end of the shaft 251, and a gear 3 151 is also meshed and connected on one side of the crown gear 252, so that the gear 3 151 can rotate together with the rotation of the crown gear 252.

[0036] The pulley 3 152 located below the gear 3 151 rotates with it, and a rotating shaft 2 15 is arranged between the bottom surface of the pulley 3 152 and the top of the upper cover 12. A rotatable impeller 6 is arranged at the opening of the butt joint 121, and only a pulley 4 61 extends upward from the upper part of the impeller 6. The pulley 4 61 and the pulley 3 152 are powered by a belt 2 153. As the stirring shaft 21 rotates, the rotation of the stirring shaft 21 can make the pulley 1 24 rotate, and then drive the pulley 2 25 on one side of the upper cover 12 through the belt 1 241. After the pulley 2 25 rotates, the gear 3 151 meshed on one side is driven through the crown gear 252 at one end. As the gear 3 151 rotates, the impeller 6 inside the butt joint 121 can be driven through the belt 2 153. After the impeller 6 rotates, the heat of the upper heater 4 can be transferred to the inside of the bottom shell 11, and then the particles inside the bottom shell 11 can be dehumidified.

[0037] A working principle of a plastic particle dehumidification device: When the plastic particles need to be dehumidified, the particles are placed inside the bottom shell 11, and then the heater 4 and the stirring shaft 21 are turned on, so that the particles inside the bottom shell 11 can be evenly heated and dehumidified. As the stirring shaft 21 rotates, the gear 1 22 provided at one end of the stirring shaft 21 can drive the gear 2 23, and after the gear 2 23 rotates, it can reversely drive the inner gear ring 5, and after the inner gear ring 5 rotates in the reverse direction, the stirring blade 51 can rotate in the reverse direction together, which can further improve the uniform heating of the particles;

[0038] When the gear 1 22 drives the meshing gear 2 23 above, the gear 2 23 rotates to make the fan blade 232 rotate together. As the fan blade 232 rotates, the airflow inside the bottom shell 11 is sucked, and then the airflow passes through the circulation pipe 3 and is heated by the heater 4 again, so that the circulation heating can be achieved.

[0039] At the same time, when the stirring shaft 21 rotates, the rotation of the stirring shaft 21 can make the pulley 1 24 rotate, and then drive the pulley 2 25 on one side of the upper cover 12 through the belt 1 241. After the pulley 2 25 rotates, the crown gear 252 at one end drives the gear 3 151 engaged on one side, and as the gear 3 151 rotates, the impeller 6 inside the butt joint 121 can be driven through the belt 2 153. After the impeller 6 rotates, the heat of the upper heater 4 can be transferred to the bottom shell 11, and then the particles inside the bottom shell 11 can be dehumidified.

[0040] It should be noted that the specific models and specifications of the motor 2 and the heater 4 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be repeated in detail.

[0041] The power supply and principle of the motor 2 and the heater 4 are clear to those skilled in the art and will not be described in detail here.

In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
