[0002] Ethylene-vinyl acetate copolymer is a general-purpose polymer, abbreviated as EVA in English. It is flammable and has a non-irritating burning odor. EVA resin is an ethylene-vinyl acetate copolymer. The general vinyl acetate content is between 5% and 40%. Compared with polyethylene, EVA introduces vinyl acetate monomer into the molecular chain, thereby reducing the high crystallinity and improving flexibility, impact resistance, filler solubility and heat sealing properties. It is widely used in foamed shoe materials, functional shed films, packaging films, wires and cables, and toys. During the production and processing of EVA particles, there will be a certain amount of moisture, so that the EVA particles need to be dried before packaging, which requires the use of a drying device to dry them.

After the preliminary drying work is completed, the staff turns on the heating plate, and preheats the first guide plate and the second guide plate through the heating plate. The discharge pipe is in an open state through the blocking component, and the EVA particles enter the inner cavity of the second drying chamber through the discharge pipe and fall on the top of the first guide plate, and then roll down to the top of the second guide plate through the first guide plate. In this process, it is convenient to dry the EVA particles again, so that the EVA particles can be fully dried, thereby improving the drying effect of the device.

[0008] Optionally, the collecting assembly includes a collecting frame, which is placed on the inner bottom wall of the second drying chamber, with protrusions connected to both ends of the bottom of the collecting frame, and a groove body that is plugged into and fits with the protrusion is installed on the inner bottom wall of the second drying chamber.

[0009] By adopting the above technical solution, the dried EVA particles can be uniformly collected through the collection frame. When the collection frame needs to be disassembled, the collection frame is lifted upward to separate the protrusions from the grooves.

When the baffle is moved out of the inner cavity of the discharge pipe, the discharge pipe can be in an open state.

[0020] In summary, the present invention has at least one of the following beneficial effects:

[0021] (1) Through the coordinated arrangement of the first drying chamber, the second drying chamber, the first guide plate, the second guide plate, the stirring assembly and the drying assembly, the EVA particles are stirred by the stirring assembly, so that the EVA particles accumulated in the first drying chamber are fully and evenly heated. The EVA particles that have been preliminarily dried roll onto the first guide plate through the discharge pipe, and then roll onto the second guide plate.

The stirring situation in the first drying chamber 1 can be observed through the observation window 12, and the EVA particles in the second drying chamber 3 can be conveniently taken out through the door body 13.

[0031] Please refer to the attached figure in the instruction manual Figure 1 A feed pipe 11 is fixedly connected to the top of the left side of the first drying chamber 1, and the EVA particles to be dried can be introduced into the inner cavity of the first drying chamber 1 through the feed pipe 11. A discharge pipe 8 is fixedly connected to the right end of the bottom of the first drying chamber 1. A guide seat 2 is obliquely installed on the inner bottom wall of the first drying chamber 1, and the lower end of the guide seat 2 is fixedly connected to the discharge pipe 8. Therefore, the EVA particles can be quickly introduced into the discharge pipe 8 through the guide seat 2, and as many EVA particles as possible are accumulated at the bottom of the inner cavity of the first drying chamber 1.

[0032] Please refer to the attached figure in the instruction manual Figure 1 and Figure 3The bottom of the discharge pipe 8 extends into the inner cavity of the second drying chamber 3, and a material blocking assembly 14 is arranged between the discharge pipe 8 and the first drying chamber 1.

When the baffle 1401 moves out of the inner cavity of the discharge pipe 8, the discharge pipe 8 can be in an open state.

[0033] Please refer to the attached figure in the instruction manual Figure 1 and Figure 2 A drying assembly 10 is provided on the top of the first drying chamber 1. The drying assembly 10 includes a nozzle 1001, which is installed on the inner top wall of the first drying chamber 1. A plurality of nozzles 1002 are connected to the bottom of the nozzle 1001 at equal intervals. A support seat 1005 is installed on the top of the first drying chamber 1. A hot air blower 1004 is installed on the top of the support seat 1005. A connecting pipe 1003 is connected between the output end of the hot air blower 1004 and the nozzle 1001. The hot air blower 1004 delivers hot air into the nozzle 1001 through the connecting pipe 1003, and dries the particles in the first drying chamber 1 through the nozzle 1002.

[0034] Please refer to the attached figure in the instruction manual Figure 1 The inner cavity of the first drying chamber 1 is provided with a stirring assembly 9, which includes a stirring shaft 902, which is rotatably connected to the inner cavity of the first drying chamber 1 through a bearing, and a plurality of stirring rods 903 are connected to the top and bottom of the stirring shaft 902 at equal intervals, and a driving motor 901 for driving the stirring shaft 902 to rotate is installed on the right side of the first drying chamber 1. When the driving motor 901 is working, the stirring rod 903 is driven to rotate through the stirring shaft 902, so that the EVA particles can be stirred, so that the EVA particles accumulated inside the first drying chamber 1 can be fully and evenly heated.

[0035] Working principle: When using the device, the EVA particles to be dried are added into the first drying chamber 1 through the feed pipe 11, and then the hot air blower 1004 starts to work. The hot air blower 1004 sends hot air into the nozzle 1001 through the connecting pipe 1003, and blows the particles in the first drying chamber 1 dry through the nozzle 1002. Then the drive motor 901 is started. When the drive motor 901 is working, the stirring rod 903 is driven to rotate through the stirring shaft 902, so as to facilitate the stirring of the EVA particles inside the first drying chamber 1, so that the EVA particles accumulated inside the first drying chamber 1 can be fully and evenly heated.

[0036] After the preliminary drying work is completed, the staff turns on the heating plate 7 and preheats the first guide plate 4 and the second guide plate 5 through the heating plate 7. At the same time, the staff controls the electric push rod 1404 to retract through the controller. The electric push rod 1404 retracts and drives the baffle 1401 to move to the right through the connecting rod 1403. At this time, the discharge pipe 8 is in an open state, and the EVA particles enter the inner cavity of the second drying chamber 3 through the discharge pipe 8 and fall on the top of the first guide plate 4, and then roll down to the top of the second guide plate 5 through the first guide plate 4. In this process, it is convenient to dry the EVA particles again, thereby improving the drying effect of the device.

[0037] Finally, the dried materials fall into the collection frame 603 for unified collection. After the device is finished working, the door body 13 is opened, and the staff lifts up the collection frame 603. The upward movement of the collection frame 603 drives the protrusion 602 to move upward, so that the protrusion 602 is separated from the collection frame 603, which makes it convenient to take out the collection frame 603 from the inner cavity of the second drying chamber 3 and remove the particles, thereby improving the practicality of the device.

[0038] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
