Description

Technical Field

[0001] This utility model relates to the field of ceramic production, and in particular to a 3D printing device for printing ceramic flower pots. Background Technology

[0002] Traditional mass production processes for flowerpots can only produce relatively simple shapes. Creating complex shapes requires handcrafting, resulting in very low production capacity. With the development of 3D printing technology, it is now possible to create complex ceramic products using 3D printed clay. However, 3D-printed ceramic flowerpots are made by directly stacking wet clay. Since wet clay has relatively low strength, stacking hollow structures or excessively high stacks can easily lead to collapse. Therefore, it is necessary to wait for the clay to dry before continuing stacking, resulting in low production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a 3D printing device for printing ceramic flower pots with high production efficiency.

[0004] To achieve the above objectives, the technical solution of this utility model is: a 3D printing device for printing ceramic flower pots, comprising a box, a lifting device, and a printing device;

[0005] The top of the box has a top opening, and the upper part of the box has a lid to cover the top opening; the sides of the box have side openings, and the sides of the box have doors to cover the side openings.

[0006] The lifting device is installed inside the box, and the lifting device includes a lifting seat that can move up and down;

[0007] The printing device is located above the lifting seat. The printing device includes a first movable seat, a second movable seat, an extruder head, and a first fan. The first movable seat can move left and right inside the housing. The second movable seat can move back and forth on the first movable seat. The extruder head and the first fan are both located on the second movable seat. There are two first fans, which are located on both sides of the extruder head. Both first fans can blow air towards the position below the extruder head.

[0008] The extrusion head extrudes the clay material and stacks it on the lifting seat to form a blank. Two first fans can dry the blank from two directions, accelerating the drying speed of the blank to improve its strength, allowing the clay to be continuously stacked and improving the efficiency of 3D printing.

[0009] Preferably, it also includes an air suction device. The lifting seat has a platform and a base plate. The bottom of the platform has a positioning pin, and the top surface of the base plate has a positioning hole and an air suction hole. The platform is positioned above the base plate. The positioning pin is inserted into the positioning hole. The bottom of the base plate has an air suction pipe that connects the air suction hole and the air suction device. When printing thin-walled ceramic flower pots, a positioning base blank needs to be printed first. Then, the flower pot blank is printed on the positioning base blank. During the printing and firing of the flower pot blank, the positioning base blank can position and support the flower pot blank, so that the flower pot blank deforms evenly.

[0010] Preferably, the bottom of the chamber is provided with a ventilation port that connects to the outside, and a second fan is installed at the ventilation port. The second fan can blow air outward, forming an airflow from the top opening to the bottom inside the chamber, which accelerates the drying speed of the printed blank.

[0011] Preferably, one end of the first fan is hinged to the second movable base, and the second movable base is equipped with a winch with a pull rope wound around it. The two ends of the pull rope are respectively connected to the two first fans. Rotating the winch can pull the first fan through the pull rope, causing the first fan to rotate around the hinge, thereby changing the airflow direction of the first fan for adjustment when printing blanks of different shapes.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are as follows: This utility model uses an extruder to stack clay into flowerpot blanks for 3D printing. During the printing process, two first fans can dry the flowerpot blanks from two directions, accelerating the drying speed of the blanks and improving their strength. This allows the clay to be continuously stacked, improving the efficiency of 3D printing. Furthermore, this utility model can print positioning blanks to reduce deformation of the flowerpot blanks, resulting in uniform deformation of the printed flowerpot blanks.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-2 As shown, this utility model discloses a 3D printing device for printing ceramic flower pots, including a box body 2, a lifting device 3, a printing device 2, and an air suction device.

[0022] The top of the chamber 2 has a top opening 21, and the upper end of the chamber 2 has a cover 22 for covering the top opening 21. The bottom of the chamber 2 has a ventilation port communicating with the outside, and a second fan 25 is provided at the ventilation port. The second fan blows air out of the chamber, creating an airflow from the top opening 21 to the bottom inside the chamber 2. The airflow is used to dry the blanks on the lifting seat. The side of the chamber 2 has a side opening 23, and the side of the chamber 2 has a door 24 for covering the side opening 23; the printed blanks can be taken out through the side opening.

[0023] The lifting device 3 is installed inside the housing and includes a lifting seat 31 that can move up and down. The lifting device 3 also includes a drive motor, a screw, and four columns. Two columns are provided on each of the left and right sides of the lifting seat 31. The lifting seat is slidably mounted on the columns. The screw is threadedly engaged with the lifting seat. The drive motor is installed inside the housing and is connected to the screw to drive the screw to rotate, thereby moving the lifting seat up or down.

[0024] like Figure 5 As shown, the lifting platform 31 has a platform 33 and a base plate 32. The bottom of the platform 33 has a positioning pin 331, and the top surface of the base plate 32 has a positioning hole 321 and an air intake hole 322. The platform 33 is positioned above the base plate 32. The positioning pin 331 is inserted into the positioning hole 321. The top of the positioning pin 331 has a base with a diameter larger than the positioning hole, creating a ventilation gap between the platform and the base plate. The bottom of the base plate 32 has an air intake pipe 4, which connects to the air intake hole and the air intake device. The air intake device is a vacuum device used to draw air through the air intake pipe into the air intake hole.

[0025] like Figure 3 and Figure 4As shown, the printing device 1 is positioned above the lifting base 31. The printing device 1 includes a first movable base 11, a second movable base 12, an extruder head 14, and a first fan 13. First sliding rods extending in a left-right direction are provided on both the front and rear sides of the housing. The front and rear ends of the first movable base 11 are respectively movable left and right on the first sliding rods on the front and rear sides of the housing. A first lead screw assembly for driving the first movable base is provided on the housing. The second movable base 12 is movable back and forth on the first movable base 11. A second lead screw assembly for driving the second movable base is provided on the first movable base. The extruder head 14 and the first fan 13 are both located on the second movable base 12. The extruder head is connected to a feeding device for feeding clay into the extruder head. An extrusion screw is provided inside the extruder head for extruding the clay from the lower end of the extruder head and stacking it on the platform to form a blank.

[0026] There are two first fans 13, one on each side of the extruder head 14. Both first fans 13 blow air downwards from the extruder head 14. One end of each first fan 13 is hinged to a second movable base 12. The second movable base 12 is equipped with a winch 15, and a pull rope 16 is wound around the winch 15. The two ends of the pull rope 16 are connected to the two first fans 13 respectively. Rotating the winch 15 pulls the pull rope 16, causing the first fan 13 to rotate around the hinge, thereby changing the downward direction of the air blown by the first fan.

[0027] In this invention, when printing ceramic blanks, a first isolation membrane is first laid on the platen, and then the clay is extruded towards the platen through the extrusion head. The extrusion head moves back and forth and left and right under the drive of the printing device, and the lifting seat moves down. The clay is stacked on the first isolation membrane to form a positioning seat blank. The first fan blows airflow onto the clay to dry it, and the downward airflow inside the box also dries the clay at the same time.

[0028] After the positioning base blank is printed, the printing plate is removed from the base plate and a new printing plate is placed on it. The new printing plate contains the dried and cured positioning base blank. The second release film is then placed on the positioning base blank, and the air extraction device removes air, causing the second release film to adhere to the positioning base blank. The extruder extrudes clay towards the printing plate, moving back and forth and left and right under the drive of the printing device, while the lifting seat moves downward. The clay is stacked on the second release film to form the flowerpot blank. After the flowerpot blank dries and sets, it is separated from the positioning base blank. The flowerpot blank is glazed, and the first and second release films are peeled off from the positioning base blank. The positioning base blank and the flowerpot blank are then combined and sent into the kiln for firing, producing a ceramic flowerpot.

[0029] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of implementation of the present utility model. All equivalent changes and modifications made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
