Description

Technical Field

[0001] This invention relates to the field of 3D printing technology, and more particularly to a ceramic printer based on slurry sealed delivery. Background Technology

[0002] 3D printing, also known as additive manufacturing, is a type of rapid prototyping technology. Commonly used printing materials can be categorized into several major types, including petrochemical products, biological products, metal products, and lime concrete products. Ceramic materials are one of these categories. Ceramic 3D printing can produce complex, high-precision, and multifunctional ceramics, which will be widely used in fields such as construction, industry, medicine, and aerospace. It also has excellent application prospects in areas such as ceramic cores, orthopedic substitutes, and catalysts.

[0003] Current ceramic 3D printers deliver materials by connecting pipes to the spray gun during the feeding process. Because the pipes are connected by snap-fit, this process cannot guarantee the sealing of the slurry during delivery, which can easily lead to slurry leakage. At the same time, since the pipes are secured by inserting snap-fit, during the printing process, as the pipes move with the spray gun, they may be pulled and cause them to fall off. Summary of the Invention

[0004] To overcome the shortcomings of existing 3D ceramic printing feeding processes that are prone to leakage, a ceramic printer based on sealed slurry delivery is provided.

[0005] The technical solution of the present invention is: a ceramic printer based on slurry sealing and conveying, comprising a printer body, a sliding nozzle component, a sliding block, an injection pipe connector, an airbag rubber ring, a fixing ring plate, and miniature air cylinders. A third electric slide rail on the printer body is slidably connected to the sliding nozzle component through the sliding block, and the sliding block is provided with an injection pipe connector that is connected to the nozzle at the bottom of the sliding nozzle component. A receiving chamber is provided around the side wall of the injection pipe connector, and an airbag rubber ring is provided in the receiving chamber. The airbag rubber ring is connected to several miniature air cylinders through the outer wall of the pipe. The miniature air cylinders are all fixedly connected to the fixing ring plate, and the fixing ring plate is fixedly connected to the outer wall of the injection pipe connector.

[0006] Furthermore, it also includes a limiting component, with a limiting component provided on the outer wall of the injection tube joint; the limiting component includes a threaded collar and a spiral sleeve, the threaded collar is fixedly connected to the outer wall of the injection tube joint, the spiral sleeve is threadedly connected to the threaded collar, and the spiral sleeve contacts the push rod of the micro air cylinder.

[0007] Furthermore, it also includes a fixing component, which is provided on the injection tube connector; the fixing component includes a tapered nail and a spring, the tapered nail is connected through the injection tube connector, and a spring is provided between the tapered nail and the injection tube connector.

[0008] Furthermore, the head of the conical nail has a circular top surface and slides in contact with the spiral sleeve.

[0009] Furthermore, it also includes a dual-feed assembly, with the injection pipe connector connected to the dual-feed assembly; the dual-feed assembly includes a feeding pipe, a loading frame, a raw material cylinder, an annular plate, a fixed sealing plate, and a spiral fastening joint. The feeding pipe is connected to the injection pipe connector, and the feeding pipe is connected to the raw material cylinder through the spiral fastening joint. The raw material cylinder is placed on the loading frame, and the annular plate is fixedly connected to the loading frame. The fixed sealing plate is fixedly connected to the annular plate, and the spiral fastening joint is slidably connected to the fixed sealing plate.

[0010] Furthermore, it also includes a movable sealing plate, which is slidably connected to the annular plate, and the movable sealing plate and the discharge port of the raw material cylinder are in contact.

[0011] Furthermore, it also includes protruding blocks, with protruding blocks symmetrically fixed to both sides of the movable sealing plate.

[0012] Furthermore, it also includes a material tube placement component, which is fixedly connected to one side of the third electric slide rail; the material tube placement component consists of a mounting plate installed on one side of the third electric slide rail and an extension plate fixed to the mounting plate, the extension plate having a slot in which the material tube is secured.

[0013] The beneficial effect is that an additional receiving chamber is added at the connection port of the sliding nozzle, and an inflatable air bladder ring is installed in the receiving chamber. The gap between the receiving chamber and the feed tube is filled by pressurized inflation, so that the ceramic printing paste is prevented from leaking out.

[0014] Under the action of the spiral sleeve, the top of the conical nail moves closer to each other as the spiral sleeve rotates, and squeezes the feed tube to achieve a fixing effect. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] A ceramic printer based on slurry sealed delivery, such as Figures 1-4As shown, the printer includes a printer body 1, a sliding printhead component 2, a sliding block 201, an injection tube connector 202, an airbag rubber ring 204, a fixing ring plate 205, and a miniature air cylinder 206. The printer body 1 consists of a first electric slide rail 101, a second electric slide rail 102, a third electric slide rail 103, an operation panel 104, a carrying plate 105, and a power distribution box 106. The third electric slide rail 103 on the printer body 1 is slidably connected to the sliding printhead component 2 via the sliding block 201. The first electric slide rail 101, the second electric slide rail 102, and the third electric slide rail 103 together enable the sliding printhead component 2 to be... The ceramic printing of the sliding nozzle 2 can be completed on the carrier plate 105 with the three-way moving orientation axis. The operation panel 104 is used to set and adjust the printer parameters. The sliding block 201 is connected to the injection pipe connector 202 and the nozzle at the bottom of the sliding nozzle 2. The side wall of the injection pipe connector 202 is surrounded by a receiving chamber 203. An air bladder rubber ring 204 is snapped into the receiving chamber 203. The air bladder rubber ring 204 is connected to four miniature air cylinders 206 through the outer wall of the pipe. The miniature air cylinders 206 are fixed to the fixed ring plate 205, and the fixed ring plate 205 is fixed to the outer wall of the injection pipe connector 202.

[0030] like Figure 3 , Figure 5 As shown, it also includes a limiting component 3, which is provided on the outer wall of the injection pipe joint 202; the limiting component 3 includes a threaded collar 301 and a spiral sleeve 302. The threaded collar 301 is fixed to the outer wall of the injection pipe joint 202, and the spiral sleeve 302 is threadedly connected to the threaded collar 301. The spiral sleeve 302 is narrow at the bottom and wide at the top, with the wide part being inclined and the narrow part contracting inward. The narrow part of the spiral sleeve 302 contacts the push rod of the micro air cylinder 206.

[0031] like Figure 3 , Figure 6 , Figure 7 As shown, it also includes a fixing component 4, which is installed on the injection tube connector 202. The fixing component 4 includes a conical nail 401 and a spring 402. The conical nail 401 is symmetrically connected to the left and right sides of the injection tube connector 202. The nail head of the conical nail 401 has a circular top surface and slides in contact with the spiral sleeve 302. The nail point is a blunt surface so that it will not puncture the tube when the two conical nails 401 are close to each other. The spring 402 is sleeved between the conical nail 401 and the injection tube connector 202. The spring 402 keeps the two conical nails 401 away from each other.

[0032] After the feed tube 501 is inserted into the injection tube connector 202, the spiral sleeve 302 is rotated to inject air into the air bladder ring 204 by the micro air cylinder 206, causing the air bladder ring 204 to expand and squeeze the feed tube 501. At the same time, the rotating spiral sleeve 302 brings the conical nails 401 on both sides closer together and clamps and fixes the feed tube 501 to prevent slippage. In this way, the ceramic printing paste is sealed and delivered.

[0033] Example 2

[0034] Based on Example 1, such as Figure 1 , Figure 8 , Figure 9 As shown, it also includes a dual-feed assembly 5, with the injection pipe connector 202 connected to the dual-feed assembly 5; the dual-feed assembly 5 includes a feed pipe 501, a loading frame 502, a raw material cylinder 503, an annular plate 504, a fixing sealing plate 5041, and a spiral fastening connector 505. The feed pipe 501 is connected to the injection pipe connector 202, and the feed pipe 501 is connected to the outlet of the raw material cylinder 503 through the spiral fastening connector 505. The raw material cylinder 503 is placed on the loading frame 503. Multiple raw material cylinders 503 can be placed on the carrier 502. In this embodiment, two are used as an example. An annular plate 504 is welded on the carrier 502. The outlet of the raw material cylinder 503 is placed inside the annular plate 504. A fixing sealing plate 5041 is fixedly connected to the annular plate 504. A notch is opened on the fixing sealing plate 5041. The notch is aligned with the outlet of the raw material cylinder 503. The spiral fastening joint 505 slides in the notch on the fixing sealing plate 5041.

[0035] like Figure 1 , Figure 10 As shown, it also includes a movable sealing plate 6, which is slidably connected to the annular plate 504. The movable sealing plate 6 has a notch for the spiral fastening joint 505 to pass through, while the other parts of the movable sealing plate 6 are in contact with the discharge port of the raw material cylinder 503 to block the discharge port, so that raw materials will not leak out when the other raw material cylinders 503 are not in use.

[0036] like Figure 1 , Figure 10 As shown, it also includes protruding blocks 7. The protruding blocks 7 are symmetrically welded on both sides of the movable sealing plate 6. The protruding blocks 7 are welded to the movable sealing plate 6 located on the outside of the annular plate 504, which can prevent the movable sealing plate 6 from being completely pulled out when it is pulled.

[0037] like Figure 1 , Figure 11As shown, it also includes a feed tube placement component 8, which is fixedly connected to one side of the third electric slide rail 103. The feed tube placement component 8 consists of a mounting plate 801 installed on one side of the third electric slide rail 103 and an extension plate 802 fixed on the mounting plate 801. The extension plate 802 has a slot 803, in which the feed tube 501 is inserted. The feed tube placement component 8 is used to collect and wind up the excess feed tube 501 to prevent the feed tube 501 from winding up during printing.

[0038] After the raw material in the raw material cylinder 503 is used up, the screw fastening joint 505 is twisted to disengage from the raw material cylinder 503 and slides onto the other side of the raw material cylinder 503 via the fixed sealing plate 5041. The feed pipe 501 is then connected through the screw fastening joint 505 to achieve the effect of quick raw material replacement.

[0039] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
