Description

Technical Field

[0001] The invention relates to the field of bee science and technology, and in particular to a 3D printing method for making honeycombs using beeswax. Background Art

[0002] The foundation is the bottom mold of the artificial beehive cell, which is specially used for bees to build honeycombs. It is a necessity for movable frame beekeeping. Because beekeeping production uses the foundation, it is embedded in the nest frame and used in conjunction with the movable frame beehive. The worker bees raise the cell wall by secreting beeswax to form honeycombs. Beeswax is the wax secreted by four pairs of wax glands in the abdomen of the bees (worker bees). The liquid wax secreted by the wax glands is white and opaque, and is in an irregular pentagon. There are about 4 million wax scales in 1kg of beeswax. It takes 50 wax scales for bees to build a worker bee cell, and 120 wax scales for building a drone cell. A strong bee colony can secrete 2kg or more of wax scales to build in a spring and summer season. It takes a lot of honey and time for bees to build a honeycomb of the size of a standard nest frame.

[0003] In the prior art, the foundation can only play a guiding role, and worker bees still need to secrete beeswax to raise the height of the honeycomb. In addition, due to the depth of the honeycomb, it is difficult to demold after traditional processing, and the manufacturing cost is high, so a thin layer of foundation is used. At the same time, the installation of the foundation also requires the addition of steel wire to the hive frame, and the steel wire needs to be electrically heated during installation so that the foundation is partially melted and adhered to the steel wire. In order to make the honeycomb hang, the beeswax must be heated so that the upper edge of the foundation adheres to the upper edge of the inner wall of the hive frame, otherwise it is easy for more bees to fall off. In addition, since the foundations are of uniform specifications, in order to match the hive frame, the existing foundations need to be cut, which requires manual operation, resulting in a long cycle and low efficiency in bee breeding. At the same time, after the foundation is installed, the bee colony needs to spend extra time and energy to process the honeycomb, thereby reducing the time and efficiency of the bee colony's honey production, and then reducing the honey production. Therefore, a 3D printing method for making honeycombs using beeswax is needed to increase honey production without the need for bees to build honeycombs. Summary of the invention

[0027] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0028] Please refer to Figures 1 to 4 , a 3D printing method for making honeycomb using beeswax, comprising:

[0029] Step 1, preheating the beeswax by using a heating device 1, the heating device 1 includes a heating and stirring barrel 11, a heat preservation barrel 12, a vibration motor 13 and an extrusion pump 14; the heating and stirring barrel 11 includes a barrel body 111, a stirring blade 112 and a stirring motor 113, the stirring blade 112 is arranged in the barrel body 111, the stirring motor 113 is arranged outside the barrel body 111 and connected to the stirring blade 112, and a heating layer is arranged on the inner wall of the barrel body 111; the barrel body 111 is provided with an inlet at the top and a discharge outlet at the bottom, the heat preservation barrel 12 is arranged on the discharge outlet, the vibration motor 13 is arranged on the side wall of the heat preservation barrel 12, and the extrusion pump 14 is connected to the heat preservation barrel 12; the collected solid beeswax is put into the inlet and the heating layer and the stirring motor 113 are started until the solid beeswax is melted into liquid beeswax and the stirring is stopped, and the liquid beeswax enters the heat preservation barrel 12 from the discharge outlet, and the vibration motor 13 is started to vibrate the liquid beeswax to discharge the air in the liquid beeswax;

[0030] Step 2: Import the shape of the honeycomb 4 to be printed into several 3D printers 2 in advance, wherein the four side edges of the honeycomb 4 are respectively provided with a plurality of connecting edges 41 and a plurality of notches 42; cut the shape of the honeycomb 4 into a multi-layer printing path, and the printing path with the connecting edge 41 is a connecting segment, and set one of the connecting segments of the bottom printing path as the starting segment; the 3D printer 2 includes a molding platform 21, a print head 22 and a cooling fan 23, the print head 22 includes a feed port and a print port that are connected to each other, the feed port is connected to the extrusion pump 14 through an insulation pipe, and the print port is arranged toward the platform; the cooling fan 23 is arranged on the side of the print head 22 and is arranged toward the print port;

[0031] Step 3, placing the unprinted nest foundation frame 3 horizontally on the forming platform 21, the nest foundation frame 3 includes four edges of the upper, lower, left and right inner walls; when the 3D printer 2 is printing, the four side edges of the shape of the honeycomb 4 to be printed are respectively aligned with the four edges of the inner wall of the nest foundation frame 3, after alignment, start the 3D printer 2, select the starting section as the starting path of 3D printing, and then print layer by layer according to the multi-layer printing path, when printing, start the extrusion pump 14 to extrude liquid beeswax from the printing port, and start the cooling fan 23 to cool the extruded liquid beeswax, when printing the starting section or the connecting section, increase the power of the extrusion pump 14 so that the liquid beeswax extrusion amount of the starting section or the connecting section is 1.2-1.5 times that of other printing paths, and at the same time turn off the cooling fan 23 or reduce the speed of the cooling fan 23 to prolong the solidification time so that the liquid beeswax maintains a certain fluidity, thereby increasing the contact area with the nest foundation frame 3 and then improving the adhesion strength between the honeycomb 4 and the nest foundation frame 3;

[0032] Step 4: remove the foundation frame 3 with the honeycomb 4 from the forming platform 21 and replace it with an unprinted foundation frame 3 to repeat step 3.

[0033] From the above description, it can be seen that by preheating the beeswax through the heating device 1 and using the beeswax as the base material for 3D printing, the bees do not need to build honeycombs 4 when building nests, and can directly use the printed honeycombs 4 without consuming beeswax and time, and without installing or adjusting the foundation, thereby shortening the preparation time for bee breeding, so that the number of bee colonies and honey production can be rapidly increased; by building honeycombs 4 by 3D printing, the foundation frame 3 does not need to be fixed by multiple steel wires or additional beeswax after melting and adhesion, so that the available space of the honeycomb 4 is larger, which can accommodate more bees or brood combs and improve space utilization; and further, through multiple connecting edges 41 and multiple notches 42, stress points and channels can be formed on the four edges of the foundation frame 3, and multiple directions can be passed, which overcomes the problem that the existing technology can only pass from the bottom or the side and cannot be lifted The density of the honeycomb 4 causes a large amount of space waste, which makes it easier for bees to pass through and further increases the space capacity, thereby increasing the number of honeycombs 4. By using more liquid beeswax in the starting section or the connecting section, combined with turning off the cooling fan or reducing the speed, the time for the liquid beeswax to penetrate the foundation frame 3 using the characteristics of the liquid state, flow and diffuse on the surface of the foundation frame 3, thereby increasing the connection area, thereby increasing the adhesion strength, and then ensuring the connection strength. Combined with the wire-free design, only one knife is needed for each side when taking honey, and it can be cut all at once, overcoming the problem of the need to pull out the knife due to the presence of steel wire in the prior art, thereby improving the efficiency of honey taking. The vibration motor 13 is used to exhaust air, and the absence of bubbles can make the printed honeycomb 4 more complete, thereby improving the quality of the honeycomb 4. At the same time, due to the absence of bubbles, it is not easy to deform under the blowing of the cooling fan 23, thereby avoiding affecting the routing.

[0034] Furthermore, the plurality of connecting sections and the plurality of notches 42 are arranged alternately.

[0035] It can be seen from the above description that the staggered connection segments and the notches 42 can achieve uniform force distribution, thereby avoiding deformation of the honeycomb 4 caused by the honeycomb 4 being overweight as a whole and uneven force distribution.

[0036] Furthermore, an air outlet 114 and an air inlet 115 are provided on the side wall at the top of the barrel body 111, and a circulating fan 116 is provided on the air outlet 114;

[0037] The insulated pipe includes a conveying pipe and an insulated pipe. The insulated pipe is sleeved on the outer circumference of the conveying pipe. There is a gap between the insulated pipe and the conveying pipe to form an air flow channel. A circulation inlet is provided on the insulated pipe at one end of the insulated pipe, and a circulation outlet is provided on the insulated pipe at the other end. The circulation inlet is connected to the air outlet 114, and the circulation outlet is connected to the air inlet 115.

[0038] From the above description, it can be seen that the bubbles produced by the vibration of the beeswax can be utilized through the air flow channel, and the heat brought by the bubbles can be utilized to achieve a constant temperature of the insulation pipe.

[0039] Furthermore, the circulation inlet is arranged close to the print head 22 .

[0040] From the above description, it can be seen that by arranging the circulation inlet close to the print head 22, the temperature of the gas just discharged is higher, and the temperature of the liquid beeswax just entering the delivery pipe is higher, thereby ensuring the temperature at the end of the delivery pipe.

[0041] Furthermore, a filter box is provided on the air outlet 114 .

[0042] From the above description, it can be seen that by setting up the filter box, impurities in the gas can be adsorbed, reducing the possibility of clogging of the insulation pipe.

[0043] Furthermore, a heat insulation layer is provided on the outer wall of the thermal insulation pipe.

[0044] Furthermore, the collected solid beeswax is put into the inlet after being prepared, and the heating layer and the stirring motor 113 are started until the solid beeswax is melted into liquid beeswax and then the stirring is stopped.

[0045] From the above description, it can be seen that by adding the mixing action, beeswax with the smell, hardness and viscosity that suits the habits of bees can be mixed as needed. For example, Italian honey bees and Chinese honey bees have different requirements for beeswax for building honeycombs 4, so mixing is needed.

[0046] Furthermore, a sealing cover is provided on the inlet at the top of the barrel body 111 , and after the solid beeswax is prepared, it is put into the inlet and then covered with the sealing cover to seal the barrel body 111 .

[0047] From the above description, it can be seen that the sealing cover can avoid heat loss, and while keeping warm, it is convenient for the subsequent circulation fan 116 to circulate heat, achieving two uses for one heating layer without the need for additional heating components for insulation and heating.

[0048] Furthermore, an air guide nozzle 24 is disposed at the bottom of the cooling fan 23, and the air guide nozzle 24 is disposed toward the printing port.

[0049] It can be seen from the above description that, by providing the air guide nozzle 24 , the cooling direction can be ensured and useless work can be avoided.

[0050] Furthermore, a plurality of notches 42 on the lower edge of some of the honeycombs 4 are connected to form a reserved space for accommodating royal jelly.

[0051] From the above description, it can be seen that by connecting multiple gaps 42 to form a reserved space for accommodating royal jelly, the requirements of different bees for the honeycomb 4 can be met without manually modifying the honeycomb 4. By setting the reserved space for part of the honeycomb 4, the printed foundation frames 3 can be combined in a certain proportion, so that when multiple foundation frames 3 are installed in the beehive, there is one to two reserved spaces for royal jelly, which meets the development needs of the bees.
