Detailed Description

The present invention will be described in detail with reference to the following examples, which are intended to illustrate but not limit the technical solutions of the present invention.

As shown in fig. 1, the present embodiment provides a 3D printing pen 1. The 3D printing pen 1 is provided with a casing 10, and the casing 10 is long, so that the overall appearance of the 3D printing pen 1 is similar to a pen-shaped structure. The 3D printing pen 1 of the present invention may be a multicolor printing apparatus, and in this embodiment, two-color printing is used as an example for explanation. It should be understood that the scope of the present invention is not limited to two-color printing. Referring to fig. 1, in the present embodiment, a first feeding/discharging port 101 and a second feeding/discharging port 102 are formed on an end surface (top surface in the figure) of the housing 10 for a user to respectively feed a first plastic 100 and a second plastic (not shown), the first plastic 100 and the second plastic are plastics with different colors, and the first plastic 100 and the second plastic may be ABS plastic or PLA plastic, or other straight strip-shaped plastics that can be melted at a temperature of 300 ℃. A nib-shaped nozzle 11 is formed on the other opposite end surface of the housing 10 to eject the first plastic 100 or the second plastic.

The internal structure of the 3D printing pen 1 is described below with reference to fig. 2 and 3.

As shown in fig. 2, the 3D printing pen 1 includes a first driving module 12, a second driving module 13 and an ejection module 14. As shown in fig. 2 and fig. 3, the first driving module 12 is disposed in the housing 10 and corresponds to the first feeding/discharging opening 101, and the first driving module 12 has a first motor 121 and a first gear set 122, so that the first motor 121 drives the first gear set 122 to feed or discharge the first plastic 100. The second driving module 13 is disposed in the housing 10 and corresponds to the second feeding/discharging opening 102, and the second driving module 13 has a second motor 131 and a second gear set 132, so that the second motor 131 drives the second gear set 132 to feed or discharge the second plastic. The injection module 14 is assembled in the housing 10, and has a heater (not shown), and corresponds to the first driving module 12 to melt the first plastic 100 and push the first plastic out of the nozzle 11, or corresponds to the second driving module 13 to melt the second plastic and push the second plastic out of the nozzle 11, so as to form a three-dimensional object or a three-dimensional image and text with two different colors in a three-dimensional space.

More specifically, referring to fig. 3 and 4, the first gear set 122 of the first drive module 12 includes: a first driving gear 1221, a first gear 1223, a first driven gear 1224, and a first roller 1225. The first driving gear 1221 is coupled to an output shaft (not shown) of the first motor 121, so that the first motor 121 drives the driving gear 1221 to rotate through the output shaft. The first driving gear 1221 is engaged with the first gear 1223, and the first gear 1223 drives the first driven gear 1224 to rotate. Since the first plastic 100 is clamped between the first roller 1225 and the first driven gear 1224, and the first roller 1225 and the first driven gear 1224 simultaneously perform opposite rotational movements, the first plastic 100 can pass along a feeding channel 1226 formed between the first roller 1225 and the first driven gear 1224 and move outwards in a linear direction. Similarly, as shown in fig. 3 and 5, the second gear set 132 of the second driving module 13 includes: a second driving gear 1321, a second gear 1323, a second driven gear 1324 and a second roller 1325. The second driving gear 1321 is coupled to an output shaft (not shown) of the second motor 131, so that the first motor 121 rotates the driving gear 1221 through the output shaft. The second driving gear 1321 is engaged with the second gear 1323, and the second gear 1323 drives the second driven gear 1324 to rotate. Since the second plastic is clamped between the second roller 1325 and the second driven gear 1324, and the second roller 1325 and the second driven gear 1324 can rotate in opposite directions, the second plastic is driven to pass through another feeding channel (not shown) formed between the second roller 1325 and the second driven gear 1324 and move outwards in a linear direction. Thus, the 3D printing pen 1 of the present embodiment can have two different color plastics at the same time.

After the feeding procedure is completed, as shown in fig. 2, the injection module 14 is provided with two receiving ports (not shown) for correspondingly receiving the first plastic 100 or the second plastic conveyed by the first driving module 12 or the second driving module 13, so that the first plastic 100 or the second plastic enters the injection module 14 through the receiving ports for hot melting, and then the first plastic 100 or the second plastic is pushed out of the nozzle 11 for a user to draw an image and perform three-dimensional molding in a three-dimensional space.

The 3D printing pen 1 further includes a heat dissipation module 16 disposed in the housing 10 and assembled between the injection module 14 and the first driving module 12 and the second driving module 13, so as to respectively receive the first plastic 100 and the second plastic introduced by the first driving module 12 and the second driving module 13, and keep the first plastic 100 and the second plastic in a solid state. As shown in fig. 2, the heat dissipation module 16 includes a first lead-in tube 161 and a second lead-in tube 162, which are respectively disposed corresponding to the first feeding/discharging opening 101 and the second feeding/discharging opening 102, and are used for respectively receiving the first plastic 100 and the second plastic fed by the first driving module 12 and the second driving module 13.

The heat dissipation module 16 further includes a heat insulation plate 163 and a plurality of heat dissipation fins 164, wherein the first inlet pipe 161 and the second inlet pipe 162 are disposed on one surface of the heat insulation plate 163, and the heat dissipation fins 164 are disposed on the opposite surfaces of the heat insulation plate to the surfaces of the inlet pipes, so as to prevent the first plastic 100 and the second plastic from being melted by the heater without entering the injection module 14. The heat dissipation module 16 is configured to prevent the first plastic 100 or the second plastic from being melted in advance only near the nozzle 11 due to the radiation heat of the heater in the injection module 14 when the first plastic 100 or the second plastic is pushed to approach the injection module 14, which may result in the first driving module 12 and the second driving module 13 not being able to push the first plastic 100 or the second plastic melted in advance, so that the heat dissipation module 16 is configured to isolate the radiation heat transferred from the heater in the injection module 14 to the first plastic 100 or the second plastic, thereby keeping the first plastic 100 or the second plastic in a solid state before entering the injection module 16.

As shown in fig. 2 and 3, the 3D printing pen 1 further includes a control module 15 for controlling the operations of the above components, such as the first driving module 12, the second driving module 13 and the ejection module 14. It will be appreciated by those skilled in the art that the control module 15 may be a PCB circuit board or a microprocessor.

In use, referring to fig. 1, first, the power key X on the housing 10 is turned on, and the first plastic 100 and the second plastic are respectively inserted into the first feeding and discharging opening 101 at one end of the housing 10. Then, as shown in fig. 4, a material guiding tube 1227 is disposed at a position of the first driving module 12 corresponding to the first feeding/discharging port 101 and the feeding passage 1226 for guiding the advancing path of the first plastic 100, and the same material guiding tube is disposed in the second driving module 13 (see fig. 5). Since the first driving module 12 and the second driving module operate in a similar manner, only the first driving module 12 is taken as an example for description, and the description of the same parts will not be repeated. Referring to fig. 1, 2 and 4, when the feeding switch a on the housing 10 is pressed, the first motor 121 electrically connected to the feeding switch a (i.e., the feeding switch B when the second driving module operates) is started, and the output shaft of the first motor 121 drives the first driving gear 1221 coupled to the output shaft to rotate. Since the first driving gear 1221 is engaged with the first gear 1223, the first gear 1223 also starts to rotate and rotates the first driven gear 1224. Thus, the first plastic 100 advances along the feeding channel 1226 as the first driven gear 1224 rotates, and the first plastic 100 drives the first roller 1225, so that the first roller 1225 and the first driven gear 1224 rotate in opposite directions. The first plastic 100 is then fed through. The first motor 121 may have a feed flow rate that may be 10mm/sec, and the second motor 131 may produce a feed flow rate that may also be 10 mm/sec. Of course, the feeding flow rate of the first motor 121 and the second motor 131 is 10mm/sec, and the discharging flow rate of the first motor 121 and the second motor 131 is also 10 mm/sec.

In other embodiments of the present invention, after the first plastic 100 passes through the feeding channel 1226, an H-shaped conduit (not shown) is further included between the first driving module 12 and the second driving module 13 and the ejection module 14, two branches of the H-shaped conduit on the same side are respectively connected to the feeding channel 1226 of the first driving module 12 and the second driving module 13, and the other end is corresponding to the first lead-in tube 161 and the second lead-in tube 162 of the heat dissipation module 16 in a displaceable manner, so as to ensure that the first plastic 100 or the second plastic can be guided to the receiving opening more accurately.

As shown in fig. 1 and 2, after the first plastic 100 enters the injection module 14, a heater (not shown) in the injection module 14 melts the first plastic 100 at a temperature of, for example, 120 ℃ to 300 ℃, but the melting temperature is specifically selected according to different types and characteristics of plastics. After the first plastic 100 is hot-melted, it is injected and molded by the nozzle 11.

Therefore, 3D print pen can solve the problem that present like product can only print the monochromatic product, through setting up the feeding subassembly more than two sets of, makes 3D print pen can load the plastics of two kinds or two kinds of above different colours, can make the user accomplish the colour conversion and form double-colored or polychrome three-dimensional image or three-dimensional object at the in-process of construction three-dimensional image or three-dimensional object through simple operation, lets 3D print pen can realize double-colored or polychrome efficiency of printing.
