DETAILED DESCRIPTION

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. Example

[0021] like Figures 1-4 As shown, this utility model provides an odor treatment and purification device for nylon 3D printing, including a printing device body 1. A front door 2 is provided at the front end of the printing device body 1. A vent 5 is fixed at the rear end inside the printing device body 1. A fixing plate 6 is fixed below the rear end of the printing device body 1. Two lead screws 7 are symmetrically arranged on the fixing plate 6. The bottom end of the lead screw 7 is rotatably connected to the fixing plate 6, and the top end of the lead screw 7 is rotatably connected to the printing device body 1. A pulley 8 is fixed at the top of each lead screw 7, and the two pulleys 8 are connected by a transmission belt 9. A servo motor is fixed at the top of the printing device body 1. 10. The output end of the servo motor 10 is fixedly connected to a pulley 8. Both lead screws 7 are threaded with transmission blocks 11. An air suction chamber 12 is set between the two transmission blocks 11. The two sides of the air suction chamber 12 are fixedly connected to the two transmission blocks 11 respectively. A fan 13 is fixed at the bottom of the fixed plate 6. Two corrugated pipes 14 are symmetrically arranged between the fan 13 and the air suction chamber 12. One end of the corrugated pipe 14 is connected to the inside of the air suction chamber 12, and the other end of the corrugated pipe 14 is connected to the air suction end of the fan 13. A purification device is installed inside the air suction chamber 12, so that the air suction chamber 12 moves with the working height inside the main body 1 of the printing device.

[0022] The specific settings and functions of this embodiment are described below: Observation windows 4 are fixed on both sides of the main body 1 of the printing device, and another observation window 4 is opened on the front door 2 of the printing device. The front door 2 of the printing device is fixedly connected to the main body 1 of the printing device through a sealing buckle 3. Sealing rubber is provided at the joint between the front door 2 of the printing device and the main body 1 of the printing device. The length of the lead screw 7 is greater than the length of the vent hole 5. Several through holes are opened at equal intervals on the vent hole 5, so that air enters the interior of the main body 1 of the printing device through the vent hole 5, while the vent hole 5 also blocks impurities from entering the air intake chamber 12. Example

[0023] like Figures 1-4 As shown, the purification device includes filter plates 15. Two filter plates 15 are symmetrically fixed inside the air intake chamber 12. An activated carbon layer 16 is provided between the two filter plates 15, so that the filter plates 15 and the activated carbon layer 16 adsorb harmful substances in the odor.

[0024] The effect achieved by the whole embodiment is that the filter plate 15 is located in the middle of the air suction chamber 12, the radius of the opening on the filter plate 15 is smaller than the radius of the through hole of the air hole 5, so that the filter plate 15 in the front section intercepts the impurities leaked by the air hole 5.

[0025] The method for using the device and the working principle are as follows: when the printing equipment body 1 works, the fan 13 is started synchronously, so that the fan 13 forms a negative pressure in the air suction chamber 12 through the corrugated pipe 14, so that the air suction chamber 12 sucks the air in the printing equipment body 1 into the air suction chamber 12, and the odor generated when the printing equipment body 1 works is also sucked into the air suction chamber 12; when the printing equipment body 1 prints the workpiece layer by layer upwards, the servo motor 10 is started, so that the servo motor 10 drives the belt pulley 8 to rotate, and the two belt pulleys 8 are connected through the transmission belt 9, so that the belt pulley 8 drives the lead screw 7 to rotate, and the lead screw 7 drives the transmission block 11 to move, so that the transmission block 11 drives the air suction chamber 12 to move, so that the air suction chamber 12 moves with the working height in the printing equipment body 1, and when the odor is sucked into the air suction chamber 12, the odor is preliminarily filtered through the filter plate 15 in the front end, the harmful substances in the odor are adsorbed through the activated carbon layer 16, and finally the odor is secondarily filtered through the filter plate 15 in the rear end and is transmitted to the inside of the fan 13 through the corrugated pipe 14 and is discharged.

[0026] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments still belong to the protection scope of the present application.
