detailed description

Below in conjunction with description accompanying drawing and embodiment the utility model content is described in detail:

As shown in Figure 1-5: a spherical 3D printing pen, which includes a spherical shell 1, a discharge nozzle 2 fixed on the outer surface of the bottom of the spherical shell 1, set in the shell 1 and communicated from bottom to top The heating discharge mechanism and the feed mechanism, the control mechanism that controls the operation of the heating discharge mechanism and the feed mechanism; the discharge end of the heating discharge mechanism communicates with the discharge nozzle 2.

Under the action of the control mechanism, the feeding mechanism sends the silk material (that is, 3D printing wire, such as PLA wire, ABS wire) into the heating and discharging mechanism, and the silk 16 is melted under the heating of the heating and discharging mechanism, and from the fixed It is sprayed out from the discharge nozzle 2 on the shell 1.

When using a traditional 3D printing pen, the user generally holds the pen holder with one hand. However, because the barrel of the traditional 3D printing pen is too thick, young children cannot hold the barrel normally like adults; in addition, the barrel of the traditional 3D printing pen is columnar, and children cannot hold the pen with two hands when operating it. Therefore, Traditional 3D printing pens are not suitable for young children, which affects their operation; and the spherical 3D printing pen of the present invention has a spherical shell 1, and young children can hold the 3D printing pen with both hands to operate, which is convenient for them to operate.

The outer surface of the shell 1 is provided with a groove 3 which is convenient for holding the shell 1 with both hands. Young children's hands are not particularly flexible, and the setting of the groove 3 conforms to ergonomics, so that when the child hugs the shell 1 of the telescopic spherical 3D printing pen, the grip is stronger and the operation is more labor-saving.

It also includes a fan 4 which is arranged at the bottom of the shell 1 and cools the discharge nozzle 2 . When the spherical 3D printing pen stops printing, the fan 4 can cool the discharge nozzle 2 to prevent the discharge nozzle 2 from scalding the user or scalding the desktop.

The central axis of the discharge nozzle 2 deviates from the center of the casing 1 .

The spherical 3D printing pen also includes a support rod 13 arranged at the bottom of the housing 1, a bar-shaped groove 14 for accommodating the support rod 13 is provided on the outer surface of the bottom of the housing 1, and one end of the support rod 13 is hinged On the groove wall of the strip groove 14, the other end of the support rod 13 is provided with a suction cup 15; the support rod 13 is a telescopic rod.

When the support rod 13 is not needed, it can be closed and hidden in the accommodating groove; when the forming height of the printing pen product needs to be controlled more precisely, the support rod 13 can be opened and the suction cup 15 can be adsorbed on the desktop. During operation, it is only necessary to adjust the telescopic height of the support rod 13 according to actual needs. The central axis of the discharge nozzle 2 deviates from the center of the housing 1, so that even if the suction cup 15 of the support rod 13 is adsorbed on the desktop, the 3D printing pen still has a large operable range.

The control mechanism includes a motor 5 and a control button 6 for driving the motor 5 to rotate forward or reversely.

The feeding mechanism includes a fixed plate 7 fixed on the top of the housing 1, a drive wheel 8 mounted on the fixed plate 7 and connected to the control mechanism, a driven wheel 9 mounted on the fixed plate 7, and a fixed plate mounted on the fixed plate. 7 below the feeding tube 10 that allows the wire material 16 to pass through, a gap for the transmission of the wire material 16 is provided between the driving wheel 8 and the driven wheel 9, and a feeding hole corresponding to the gap is provided on the top of the housing 1 , the discharge end of the feeding pipe 10 communicates with the heating discharge mechanism.

The heating and discharging mechanism includes a barrel 11 arranged in the lower part of the casing 1 and a heating unit 12 covering the outer wall of the barrel 11. The two ends of the barrel 11 are respectively connected to the discharge nozzle 2 and the feeding mechanism. connected. As shown in the figure, the barrel 11 communicates with the discharge end of the feeding tube 10 . The feed hole, the gap, the feed pipe 10, the barrel 11 and the discharge nozzle 2 communicate to form a feed channel.

The silk material 16 enters the gap from the feeding hole, when the control button 6 is pressed to control the motor 5 to drive the driving wheel 8 to rotate forward, the driving wheel 8 makes the driven wheel 9 rotate forward synchronously, and the silk material is transported; the silk material 16 enters through the feeding pipe 10 The material is melted in the barrel 11 under the heating of the heating unit 12 , and the melted silk material is ejected from the discharge nozzle 2 . When pressing the control button 6 to control the motor 5 to drive the driving wheel 8 to reverse, the driving wheel 8 drives the driven wheel 9 to reverse synchronously, and the silk material 16 is retracted to stop conveying.
