Detailed Description
The invention is described in detail below with reference to the figures and the specific embodiments.
If fig. 1 ~ 4, the embodiment provides an automatic feed device of photocuring 3D printer, including storage bottle 1, bottle lid 3, sealing washer 2, valve rod 5, extensible member and base 6, the required resin material is printed in the storage bottle 1 facial make-up, and bottle lid 3 is provided with runner 8, and the storage bottle 1 bottom is established to bottle lid 3 cover, and runner 8 and storage bottle 1 inside intercommunication can make the resin material in the storage bottle 1 flow from the runner 8 of bottle lid 3. The telescopic part is positioned on the valve rod 5, and in order to simplify the structure, the telescopic part adopts a spring 4, and the spring 4 is sleeved on the valve rod 5. The top of the valve rod 5 is connected with the sealing ring 2, the sealing ring 2 is positioned above the flow channel 8, the top of the spring 4 is connected with the bottle cap 3, and the bottom of the spring 4 is connected with the bottom of the valve rod 5.
The base 6 comprises a trough 15 and a slot 13, a through groove 14 is arranged between the trough 15 and the slot 13, and resin materials flowing out of the material bottle 1 reach the trough 15 through the slot 13 and the through groove 14 so as to be printed in a 3D mode. The slot 13 is provided with a boss 9, and the bottom of the valve rod 5 is positioned on the boss 9. As shown in fig. 2, in a normal state, the spring 4 pushes the valve rod 5 downwards, the sealing ring 2 moves downwards, and the sealing ring 2 blocks the upper part of the flow passage 8, so that the resin material in the material bottle 1 cannot flow out. As shown in fig. 3, when the stem 5 is pressed down, the spring 4 is compressed, the stem 5 pushes up the packing 2, and the liquid seal surface 11 of the cap 3 is opened, so that the resin material in the flask 1 flows down. The caps 3 are positioned in the slots and the flow channels 8 communicate with the slots 13 to allow the resin material to enter the pockets 15.
As shown in fig. 2 and 4, the bottom end of the bottle cap 3 is provided with a plurality of side openings 12, each of the side openings 12 is communicated with the flow channel 12, and any one of the side openings 12 faces the through groove 14. The number of the side openings 12 is preferably 4, while the size and height of each of the side openings 12 are set to be different from each other. Therefore, by rotating the material bottle 1, the side openings 12 with different sizes and heights are aligned with the through groove 14, so that the flow rate and the height of the resin material can be controlled, and the structure is very simple and easy to operate.
In order to facilitate quick replacement of the bottle cap 3, the material bottle 1 is provided with an external thread, the bottle cap 3 is provided with an internal thread, and the bottle cap 3 is in threaded connection with the material bottle 1 to realize quick disassembly and assembly. Meanwhile, the L-shaped clamping groove 7 is formed in the outer side of the bottle cap 3, the annular connecting protruding block 10 matched with the L-shaped clamping groove 7 is arranged on the inner side wall of the slot 13, the bottle cap 3 is quickly fixed in the slot 13 by pressing the bottle cap 3 downwards and rotating, and the bottle cap can be quickly disassembled as opposed to being fixed.
In order to avoid corrosion during the long-term soaking of the liquid, the material bottle 1, the bottle cap 3 and the valve rod 5 are made of corrosion-resistant plastics or metals, for example, the plastics are polypropylene resin, the metals are stainless steel, and the spring 4 is also made of stainless steel. In order to improve the sealing performance of the sealing ring 2, the sealing ring 2 is made of silica gel.
The implementation principle process is as follows: before using, the material bottle 1 filled with resin material needs to be tightly twisted with the bottle cap 3, at this time, under the pushing force of the natural stretching force of the spring 4, the valve rod 5 drives the sealing ring 2 to be attached to the liquid sealing surface 11 at the edge of the flow channel 12 of the bottle cap 3, the flow channel 12 is closed, and liquid is sealed in the material bottle 1 and cannot flow out. When the bottle cap is used, the bottle cap 3 needs to be downward and is forcibly pressed down along the slot 13 of the base 6, at the moment, the boss 9 in the middle of the slot 13 jacks up the valve rod 5, the spring 4 contracts, the sealing ring 2 rises along with the spring, the flow channel 12 is opened, the resin material flows out from the arrow direction shown in the figure, finally when the liquid level overflows the side opening of the bottle cap 3, the resin material stops flowing out, in the consumption process of the resin material, the liquid level drops below the side opening 12 of the bottle cap 3, the resin material flows out again, and finally the liquid level is kept in a stable height range.
The principle utilizes the atmospheric pressure balance principle, does not need an additional pneumatic or electric structure, and greatly saves the cost. The pressure at the bottom of the bottle cap 3 is equal to the pressure at the height of the liquid level of the material groove 15, and the pressure of the gas in the bottle to the liquid level of the photosensitive resin at the bottom of the bottle cap 3 is forced to be equal to one atmosphere (the atmospheric pressure of the liquid level of the material groove 15). Therefore, as long as the liquid level is lower than the side opening 12 of the bottle cap 3, atmospheric pressure replenishes gas into the bottle, the gas pressure in the bottle is increased, gravity replenishes liquid in the bottle to the trough 15, the liquid level is higher than the side opening 12 of the bottle cap 3 again, the pressure finally reaches balance again, and the liquid stops flowing out. This process repeats itself to maintain the liquid level at a liquid level at all times.
By adopting the technical schemes, the quantitative automatic feeding device is beneficial to environment-friendly quantitative automatic feeding according to the atmospheric pressure balance principle, the size of the bottle cap can be set according to the required flow rate and the liquid level height, the rotary clamping structure is arranged at the joint of the bottle cap and the slot, the bottle cap is convenient to fix and detach quickly, the space utilization rate is high, a machine table does not need to be customized specially, the structure is simple, the manufacturing cost is low, energy sources such as electric power and the like are not needed, the cleaning is simple, the operation and management of personnel are not needed, and the quantitative automatic feeding.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
