Description

Technical Field

[0001] The utility model belongs to the technical field of 3D printing equipment, and specifically relates to a ceramic 3D printer. Background Art

[0002] With the continuous development of science and technology, 3D printing technology has gradually penetrated into various fields. Ceramic 3D printers, as one of them, can achieve higher precision and efficiency in the manufacture of ceramic products. However, in the process of ceramic 3D printing, due to the characteristics of ceramic materials, the printed products often need to be air-dried to remove excess moisture to ensure the quality and stability of the products. The existing patent application number is CN202321499623.9, which is a 3D printing ceramic forming air-drying device. By driving the blow pipe to rise and fall, the printed product can be air-dried, but the air outlet position is fixed. During the printing process, since the product cannot be moved, it is difficult to air-dry the product well by continuously outlet air at the same position. Utility Model Content

[0003] Based on the problems mentioned in the above background technology, the utility model provides a ceramic 3D printer for solving the problem that the current printing equipment continuously outputs air at the same position and it is difficult to air dry the product well.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A ceramic 3D printer comprises a chassis, wherein a forming table, a controller, a first linear slide, a second linear slide and a third linear slide are arranged in the chassis, wherein the first linear slide is mounted on the slide of the third linear slide, the second linear slide is mounted on the slide of the first linear slide, a print head is mounted on the slide of the second linear slide, and the three linear slides cooperate to drive the print head to move in three axes, an air dryer is installed in the chassis, the air dryer comprises an annular ventilation duct and an air shield, the annular ventilation duct is connected to an air inlet duct, a plurality of exhaust holes are arranged on the inner side of the annular ventilation duct, the air shield is sleeved on the annular ventilation duct, and the air shield and the annular ventilation duct can rotate relative to each other, a reserved opening is arranged on the inner side of the air shield, a gear ring is arranged on the outer side of the air shield, a motor is mounted on the annular ventilation duct, and the motor is connected to the gear ring through a gear.

[0006] On the basis of the above technical solution, the utility model also includes:

[0007] Furthermore, observation windows are provided on both sides of the chassis, glass plates are embedded in the observation windows, and a door is installed at the front end of the chassis, so that the printing status can be observed conveniently through the observation windows.

[0008] Furthermore, a ball groove is provided at the top end of the annular ventilation pipe, and balls are arranged in the ball groove. The friction resistance between the wind shield and the annular ventilation pipe is reduced by the balls, enabling the motor to easily drive the wind shield to rotate.

[0009] Furthermore, a vertical first guide rod is installed in the chassis. A first sliding sleeve is slidably installed on the first guide rod. The first sliding sleeve is fixedly connected to the annular ventilation pipe. A horizontal second guide rod is installed on the annular ventilation pipe. A second sliding sleeve is slidably installed on the second guide rod. The second sliding sleeve is fixedly connected to the slide of the first linear slide rail. When the second linear slide rail rises to drive the print head to rise for printing, it can also drive the annular ventilation pipe to rise. At the same time, the second sliding sleeve can slide along the second guide rod without hindering the movement of the print head.

[0010] Advantages of the present utility model:

[0011] By introducing air into the annular ventilation pipe and spraying it out from the reserved opening, the printed object can be air-dried, improving the hardening speed of the printed product and preventing collapse. At the same time, by driving the wind shield to rotate by the motor to change the position of the reserved opening, the annular ventilation pipe can air-dry the printed product from different angles, improving the air-drying effect. At the same time, since the air outlet position is in a continuous moving state, it is not easy to affect the adhesion between the newly discharged material of the print head and the product.

Specific embodiments

[0019] To enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] As Figures 1 to 4 shown, a ceramic 3D printer of the present utility model includes a chassis 1. Inside the chassis 1, there are a forming table 2, a controller, a first linear slide rail 41, a second linear slide rail 42 and a third linear slide rail. The first linear slide rail 41 is installed on the slide table of the third linear slide rail. The second linear slide rail 42 is installed on the slide table 411 of the first linear slide rail 41. A print head 5 is installed on the slide table of the second linear slide rail 42. The cooperation of the three linear slide rails can drive the print head 5 to move in three axes. An air dryer 3 is installed inside the chassis 1. The air dryer 3 includes an annular ventilation pipe 31 and a wind shield 32. The annular ventilation pipe 31 is connected with an air inlet pipe. A number of exhaust holes 311 are provided inside the annular ventilation pipe 31. The wind shield 32 is sleeved on the annular ventilation pipe 31 and the wind shield 32 and the annular ventilation pipe 31 can rotate relative to each other. A reserved port 321 is provided on the inner side of the wind shield 32. A gear ring 322 is provided on the outer side of the wind shield 32. A motor 30 is installed on the annular ventilation pipe 31. The motor 30 is in transmission connection with the gear ring 322 through a gear. During the printing process, by introducing air into the annular ventilation pipe 31 and spraying it out from the reserved port 321, the printed object can be air-dried. At the same time, the motor 30 drives the wind shield 32 to move continuously to change the position of the reserved port 321.

[0021] Specifically, observation windows 11 are provided on both sides of the chassis 1. Glass plates are embedded in the observation windows 11. A box door is installed at the front end of the chassis 1. Through the observation windows 11, it is convenient to observe the printing state inside the chassis 1.

[0022] Specifically, a ball groove 323 is provided at the top end of the annular ventilation pipe 31. A ball is placed in the ball groove 323. The friction resistance between the wind shield 32 and the annular ventilation pipe 31 is reduced through the ball, so that the motor 30 can easily drive the wind shield 32 to rotate.

[0023] Specifically, a vertical first guide rod 43 is installed inside the chassis 1. A first sliding sleeve 35 is slidably installed on the first guide rod 43. The first sliding sleeve 35 is fixedly connected with the annular ventilation pipe 31. A horizontal second guide rod 33 is installed on the annular ventilation pipe 31. A second sliding sleeve 34 is slidably installed on the second guide rod 33. The second sliding sleeve 34 is fixedly connected with the slide table 411 of the first linear slide rail 41. When the second linear slide rail 42 rises to drive the print head 5 to rise for printing, it can also drive the annular ventilation pipe 31 to rise. At the same time, the second sliding sleeve 34 can slide along the second guide rod 33 without hindering the movement of the print head 5.

[0024] During the printing process, the printing head 5 discharges materials, and at the same time, the position of the printing head is changed through the cooperation of the first linear slide rail 41, the second linear slide rail 42 and the third linear slide rail to lay materials layer by layer on the forming table 2 for printing. At the same time, air is ventilated into the annular ventilation pipe 31 and ejected from the exhaust holes 311 at the reserved opening 321 to dry the printed object. At the same time, the motor 30 drives the wind shield 32 to move to change the position of the reserved opening 321, so as to dry the printed product from different positions.
