Description

TECHNICAL FIELD

[0001] The utility model relates to dehumidification moistureproof device technical field especially a 3D model room dense shelf moistureproof device under reciprocating opening and closing space. BACKGROUND

[0002] There are various 3D printing materials, such as filamentous plastics (PLA, ABS, etc.), powdered metals, resins, etc. For filamentous plastic materials, moisture can affect their flowability and toughness. In the printing process, the moisture of PLA material can cause the phenomenon of stringing, resulting in rough printing surface. This is because moisture forms bubbles in the material, and when the material is extruded for printing, the bubbles burst, causing the material to be unevenly extruded.

[0003] Moisture can cause powdered materials to clump. For example, metal powder is used in the selective laser sintering (SLS) process, and moisture clumping can affect the uniformity of powder laying. This can cause the density of the printed part to be uneven, affecting its mechanical properties, such as strength and hardness. Moisture can also affect the curing properties of resin materials, which can cause printing failure or insufficient strength of the printed part. 3D printing materials and printed models need to be stored dry and cannot be stacked, otherwise they may be deformed due to extrusion, so they need to be placed on shelves layer by layer.

[0004] A dense shelf is a dense storage device that can greatly improve space utilization compared to traditional shelves. In limited space, dense shelves can tightly arrange multiple shelf bodies through a track system. When printing materials need to be accessed or 3D models need to be placed, only a handle needs to be shaken to form a channel between the shelf bodies, and the shelf bodies can be closed to save a lot of aisle space. This efficient space utilization method is particularly suitable for units with limited land resources and limited office space.

[0005] Installing a dehumidifier in a 3D model room is a common and effective moisture-proof measure. For dense shelves, due to high space utilization, air flow is basically stopped when the dense shelves are closed. Therefore, the dense shelves need to be opened regularly to maintain sufficient air exchange and prevent moisture and mold in the closed space. INVENTION CONTENTS

Specific implementation

[0022] As Figures 1-4 The embodiment 1 shown in the figure:

[0023] A kind of 3D model room dense shelf damp-proof device, for the damp-proof of 3D model room dense shelf space, including:

[0024] Annular net rack 1;The outer layer 2 of the annular net rack 1 is encapsulated with reusable moisture absorption particles;The inner layer 3 of annular net rack 1 is provided with PCT heater 4 in axial direction;

[0025] Magnetic top shell 5;The annular net rack 1 is installed in the lower part of magnetic top shell 5;The upper end of magnetic top shell 5 is provided with at least two magnets 6;The magnet 6 is used for magnetic top shell 5 and annular net rack 1 to be magnetically attracted to dense shelf;The magnetic top shell 5 is provided with master control switch 7 for controlling PCT heater 4;The front end surface of the magnetic top shell 5 is provided with photoelectric proximity switch 8 for controlling PCT heater 4;The photoelectric proximity switch 8 is in the off state in the closed state of dense shelf, and the photoelectric proximity switch 8 is in the on state in the open state of dense shelf.

[0026] In order to prevent fire, the temperature setting of PCT heater 4 should be lower than 100 degrees, so that the deformation or melting of annular net rack 1 can be prevented.PCT heater 4 does not need temperature feedback, and is safe to use.When the dense shelf is in the open state, the photoelectric proximity switch 8 is turned on under the condition that the master control switch 7 is turned on, and the moisture absorption particles heated by PCT heater 4 will discharge the absorbed water vapor to the larger space of 3D model room, which is absorbed by dehumidifier.When the dense shelf is closed, PCT heater 4 is turned off, and the moisture absorption particles that release water vapor continue to dehumidify in the relatively closed space.

[0027] Further optimize the embodiment, the left end of the annular net rack 1 of a kind of 3D model room dense shelf damp-proof device is provided with axial flow fan 9;The blowing direction of the axial flow fan 9 points to the outer layer space of annular net rack 1;The axial flow fan 9 and PCT heater 4 are power supply linkage.

[0028] The axial flow fan 9 blows the PCT heater 4 of the annular net rack 1, enhances the flow of hot air, and reduces the drying time of the moisture-absorbing particles in the repeated use in the opened state of the dense rack.

[0029] Further optimization of the embodiment, the right end of the annular net rack 1 of the 3D model room dense rack moisture-proof device is provided with a detachable sealing cover 10.

[0030] Since the drying temperature is not higher than 100 DEG C, the repeated use of the moisture-absorbing particles has a certain regeneration rate, and therefore the detachable cover 10 can open one side of the annular net rack 1 to facilitate the replacement of the moisture-absorbing particles.

[0031] Further optimization of the embodiment, the upper end face of the magnetic top shell 5 of the 3D model room dense rack moisture-proof device is provided with a storage bin 11 for containing camphor blocks, and the side face of the storage bin 11 is provided with a ventilation hole 12.

[0032] The space above the magnetic top shell 5 is utilized, and with the opening of the axial flow fan 9, the volatilization and diffusion of the camphor blocks in the storage bin 11 can be enhanced, and the 3D model material borer oviposition can be prevented.

[0033] Further optimization of the embodiment, the axial flow fan 9 of the magnetic top shell 5 of the 3D model room dense rack moisture-proof device is provided with a forward and reverse switching switch 13.

[0034] The reverse axial flow fan 9 can quickly discharge the moisture in the space near the dense rack to the outside of the dense rack, so that the air flow diffuses outwardly more directionally, and when the moisture-absorbing particles are dried, the reverse axial flow fan 9 can quickly eliminate the moisture near the dense rack, and the moisture-absorbing particles in the heating state will not absorb the moisture when the axial flow fan 9 is reversed.

[0035] Further optimization of the embodiment, the reusable moisture-absorbing particles of the 3D model room dense rack moisture-proof device are silica gel drying particles.

[0036] The silica gel drying particles belong to physical adsorption, have strong oxidation resistance, longer service life, large adsorption capacity, and higher revival rate in repeated use.
