Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-8The figure shows a material bin mounting structure for a 3D printer, including a body 101. A printing substrate 107 is mounted inside the bottom of the body 101 via a track. A printing operation cylinder 103 is mounted inside the body 101 via a multi-axis drive frame 102. A hopper 105 is provided on one side of the printing operation cylinder 103. A first feed pipe 106 and a second feed pipe 104 are respectively provided on the opposite side of the printing operation cylinder 103 and the hopper 105. A solenoid valve is provided on the side wall of the second feed pipe 104. The figure also includes a connecting component for connecting the printing operation cylinder 103 and the hopper 105, which is provided at the opposite end of the first feed pipe 106 and the second feed pipe 104.

[0026] The connecting assembly includes a first connecting plate 201 and a second connecting plate 203 fixedly connected to opposite ends of the first conveying pipe 106 and the second conveying pipe 104. The first connecting plate 201 has two symmetrically arranged T-slots 202 on the side near the second connecting plate 203. One end of the two T-slots 202 passes through the first connecting plate 201, and the other end does not pass through the first connecting plate 201. The second connecting plate 203 has two T-plates 204 fixedly connected to the side near the first connecting plate 201. The two T-plates 204 are matched with the T-slots 202 and are connected to the second connecting plate 203 by a plurality of countersunk bolts. The first connecting plate 201 is provided with a limiting assembly for limiting the two T-plates 204, and the second connecting plate 203 is provided with a sealing assembly for sealing the connecting surface of the first connecting plate 201.

[0027] It should be noted that, through the design of the connecting components, and with the cooperation of the limiting components and the driving components, the hopper 105 is securely installed on one side of the printing operation cylinder 103 while being mounted on it. Compared with the existing technology, the hopper 105 can be installed and disassembled in a confined space without the need for special tools, thereby improving the convenience of installing and disassembling the hopper 105.

[0028] It is worth noting that the printing operation cylinder 103 is existing technology. For its specific structure and working principle, please refer to the publicly available technology CN219133242U, "A Melting and Extrusion Device for Particulate Materials". It will not be described in detail here.

[0029] Please see Figure 4 and Figure 5The limiting component shown in the figure includes two fixing holes 301 opened in the first connecting plate 201. The two fixing holes 301 are respectively connected to two T-slots 202. The two fixing holes 301 are connected to the limiting blocks 302 through the extrusion component. The two limiting blocks 302 have inclined surfaces 303 on the side away from the bottom wall of the T-slots 202. The two T-plates 204 have limiting holes 304 on the side close to the T-slots 202. The two limiting holes 304 are matched with the limiting blocks 302. The first connecting plate 201 is provided with a driving component for driving the two limiting blocks 302.

[0030] It should be noted here that the limiting component is used to ensure the firmness of the connection between the first connecting plate 201 and the second connecting plate 203.

[0031] Please see Figure 4 and Figure 7 The extrusion assembly shown in the figure includes a square plate 401 slidably connected to the side of the first connecting plate 201 away from the second connecting plate 203. One end of the square plate 401 is connected to the limiting block 302. A first spring 402 is sleeved on the side wall of the square plate 401 inside the fixing hole 301. The two ends of the first spring 402 are respectively connected to the limiting block 302 and the bottom wall of the fixing hole 301.

[0032] It should be noted here that the compression component is used to guide and reset the movement of the limit block 302.

[0033] Please see Figure 4 and Figure 7 The driving assembly shown in the figure includes a strip plate 501 that is slidably connected to the side of the first connecting plate 201 away from the second connecting plate 203, and two square plates 401 that are away from the limiting block 302 are connected to the strip plate 501 at one end. The driving plate 502 is fixedly connected to the side of the strip plate 501 away from the bottom wall of the T-slot 202.

[0034] It should be noted here that the configuration of the drive component facilitates the release of the connection limit between the first connecting plate 201 and the second connecting plate 203.

[0035] Working principle: When performing 3D printing, the hopper 105 filled with printing material needs to be installed on one side of the printing operation cylinder 103. During the installation of the hopper 105, hold the hopper 105 and bring the second connecting plate 203 at one end of the second feeding pipe 104 close to the first connecting plate 201 at one end of the second feeding pipe 104. Then, insert the T-shaped plate 204 of the second connecting plate 203 into the T-shaped groove 202 of the first connecting plate 201.

[0036] Furthermore, during the sliding process of the T-shaped plate 204 within the T-slot 202, when one end of the T-shaped plate 204 abuts against the limiting block 302, under the interaction force of the inclined surface 303 and the guiding action of the square plate 401, the limiting block 302 will be pushed away from the second connecting plate 203. As the second connecting plate 203 is continuously pushed, when the T-shaped plate 204 abuts against the bottom wall of the T-slot 202, the limiting block 302 will engage with the limiting hole 304 of the T-shaped plate 204. Thus, under the elastic action of the extrusion assembly, the limiting block 302 is pushed into the limiting hole 304 and abuts against the bottom wall of the limiting hole 304. Thus, under the pressing action of the limiting block 302 and the insertion action of the T-slot 202 and the T-shaped plate 204, the connection and limiting of the first connecting plate 201 and the second connecting plate 203 are achieved, which is then used for the hanging installation of the hopper 105 on one side of the printing operation cylinder 103.

[0037] After the hopper 105 is installed, 3D printing can be performed. During printing, the printing material in the hopper 105 will be transported from the second feed pipe 104 and the first feed pipe 106 to the printing operation cylinder 103. Then, the heating mechanism will heat it and keep the temperature stable. The fan in the heat dissipation mechanism will run to dissipate heat. The drive motor in the reduction transmission mechanism will rotate to drive the screw to rotate, and the molten material will be extruded from the nozzle. After the extrusion state is stable and the material extrusion speed is constant, each axis will work according to the running command to complete the printing.

[0038] When it is necessary to disassemble the hopper 105, the operator holds the hopper 105 with one hand and pushes the drive plate 502 with the other hand. Under the pushing force, the strip plate 501 drives the limiting block 302 at one end of the square plate 401 to move out of the limiting hole 304, thereby releasing the connection limit between the first connecting plate 201 and the second connecting plate 203. At this time, the disassembly of the hopper 105 is completed. Therefore, through the setting of the connecting components, with the cooperation of the limiting components and the drive components, the hopper 105 is securely installed on one side of the printing operation cylinder 103 while ensuring the installation of the hopper 105. Compared with the existing technology, the hopper 105 can be installed and disassembled in a small space without the use of special tools, thereby improving the convenience of installing and disassembling the hopper 105.

[0039] Example 2

[0040] Please see Figure 6 and Figure 8 This embodiment further illustrates Example 1. The sealing assembly shown in the figure includes a sealing hole 601 opened on the side of the second connecting plate 203 near the first connecting plate 201. The sealing hole 601 is provided with a sealing rubber ring 602. The two T-shaped plates 204 are provided with expansion assemblies for expanding the sealing rubber ring 602.

[0041] It should be noted that, through the setting of the sealing component, under the action of the expansion component, the sealing rubber ring 602 is expanded by air by utilizing the connection limiting function of the first connecting plate 201 and the second connecting plate 203. The expanded sealing rubber ring 602 will abut against the side wall of the first connecting plate 201, thereby sealing the connection surface of the first connecting plate 201 and the second connecting plate 203, thus improving the connection sealing effect between the first connecting plate 201 and the second connecting plate 203.

[0042] Please see Figure 6 and Figure 8 The expansion assembly shown in the figure includes a mounting hole 701 on the end of the T-shaped plate 204 away from the first connecting plate 201. The mounting hole 701 is fixedly connected to an air injection pipe 702. The air injection pipe 702 is slidably connected to an air injection plate 703. The air injection pipe 702 is connected to a sealing rubber ring 602 through a connecting pipe 704. The second connecting plate 203 has an L-shaped mounting groove 705. The connecting pipe 704 is installed in the L-shaped mounting groove 705. A clamping rod 706 is fixedly connected to the side of the air injection plate 703 away from the connecting pipe 704. One end of the clamping rod 706 passes through the limiting hole 304. A second spring 707 is sleeved on the side wall of the clamping rod 706 inside the air injection pipe 702. The two ends of the second spring 707 are respectively connected to the side wall of the air injection plate 703 and the side wall of the air injection pipe 702.

[0043] It should be noted that, due to the expansion component, when the limiting block 302 is inserted into the limiting hole 304, it will push the clamping rod 706, thereby causing the air injection plate 703 at one end of the clamping rod 706 to slide in the air injection pipe 702. Then, under the action of air pressure difference, the gas in the air injection pipe 702 is squeezed into the sealing rubber ring 602 through the connecting pipe 704, thereby causing the sealing rubber ring 602 to expand under the air. The expanded sealing rubber ring 602 will abut against the side wall of the first connecting plate 201.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
