Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding devices, in particular to an automatic connection feeding device for a printer. Background Technique

[0002] 3D printers mainly include digital manufacturing technology, materials science, and computer graphics. Digital manufacturing technology is the core of 3D printing technology, which includes a series of digital process flows, such as three-dimensional modeling, slicing, printing, and post-processing. Materials science also plays an important role in the development of 3D printing technology because the success of 3D printing technology depends on the types and properties of the materials used. Computer graphics provides a method to convert three-dimensional models into two-dimensional slice data, which is then used to control the printing process of 3D printers.

[0003] However, existing printer devices usually have a single material tray installed on the side, and the motor feed gear at the nozzle engages with a pulley to feed the wire material. However, this wire feeding method requires manual material replacement, with a low degree of automation, which severely restricts the types and quality of prints. Especially when printing large model products, manual operation is required to ensure that a new wire material is replaced in a timely manner at the moment when the previous roll of material is used up. In this case, manual operation to connect and replace the wire is prone to human error, resulting in untimely material replacement, no wire output from the nozzle, and partial vacancies in the finished model, ultimately leading to printing failure and thus reducing the working efficiency of the printer. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides an automatic connection feeding device for a printer.

[0005] The utility model is implemented by the following technical solutions: An automatic connection feeding device for a printer includes a main body mechanism, a feeding mechanism, and a discharging mechanism. The feeding mechanism is located on the left side of the main body mechanism, and the discharging mechanism is located on the left side of the feeding mechanism;

[0006] The main body mechanism includes a material placement table, a wire material tray is snap-connected to the top of the material placement table, the wire material tray is snap-connected with a snap, a wire material is rotatably connected inside the wire material tray, a limiting plate is arranged on the top of the material placement table, a protective plate is fixedly connected to the top of the material placement table, and a first sensor is fixedly connected to the top of the protective plate.

[0007] As a further improvement of the above solution, the wire material tray is arranged outside the protective plate, there are two wire material trays, and the two wire material trays are symmetrically and evenly distributed on both sides with the center of the material placement table as the center, and there are two first sensors.

[0008] Through the above technical solution, by setting the first sensor, when feeding the material, the printing device can quickly know that the device filament is about to be used up. After the sensor receiver receives the command, the feeding rate of the printer is reduced, and at the same time, it waits for the command of the second sensor.

[0009] As a further improvement of the above solution, the feeding mechanism includes a mounting base. A support column is fixedly connected to the top of the mounting base. A motor bracket is fixedly connected to the top of the support column. An encoder motor is fixedly connected to the top of the motor bracket. A first sensor receiver is arranged on the top of the encoder motor. A second sensor receiver is arranged on the top of the encoder motor. Feeding plates are arranged on both sides of the mounting base. A special gear is arranged inside the mounting base. A first gear is arranged on the left side inside the mounting base. A second gear is arranged on the right side inside the mounting base. A feeding port is arranged on the front of the feeding plate. A feeding pipe is rotatably connected to the feeding port.

[0010] As a further improvement of the above solution, there are four support columns. The four support columns are symmetrically and evenly distributed around the center of the bottom of the mounting base. The special gear is fixedly connected to the encoder motor at the top. The first gear is rotatably connected inside the feeding plate.

[0011] Through the above technical solution, by setting the second sensor, when the command of the second sensor is received by the second sensor receiver, the rotation speed of the encoder motor stops and rotates in the reverse direction, so that the filament is reconnected, and at the same time, the used filament wheel is replaced, realizing the automatic connection and feeding of the printer.

[0012] As a further improvement of the above solution, the discharging mechanism includes a fixing plate. A connecting plate is fixedly connected to the outer surface of the fixing plate. A mounting block is fixedly connected to the top of the fixing plate. A discharging port is arranged on the front of the mounting block. A second sensor is fixedly connected to the top of the mounting block. A limiting block is fixedly connected to the top of the mounting block.

[0013] As a further improvement of the above solution, one end of the connecting plate is connected to the mounting base and the other end is connected to the mounting base. The inside of the mounting block is hollow. The discharging port is arranged at the center of the front of the mounting block.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By setting the first sensor in the present utility model, when feeding the material, the printing device can quickly know that the device filament is about to be used up. After the sensor receiver receives the command, the feeding rate of the printer is reduced, and at the same time, it waits for the command of the second sensor.

[0016] The utility model realizes the automatic connection and feeding of the printer by setting a second sensor. When the command of the second sensor is received by the second sensor receiver, the rotation speed of the encoder motor stops and rotates in the reverse direction, so that the wire material is reconnected, and at the same time, the used wire material wheel is replaced.

[0028] The feeding mechanism 2 includes a mounting base 201. A support column 202 is fixedly connected to the top of the mounting base 201. A motor bracket 203 is fixedly connected to the top of the support column 202. An encoder motor 204 is fixedly connected to the top of the motor bracket 203.

[0029] There are four support columns 202, and the four support columns 202 are symmetrically and evenly distributed around the bottom center of the mounting base 201. The special gear 208 is fixedly connected to the encoder motor 204 at the top. The first gear 209 is rotatably connected inside the outlet plate 207.
