Description

Technical Field

[0001] The utility model relates to the technical field of horticultural cultivation substrate preparation, in particular to an integrated solidified substrate preparation device. Background Art

[0002] With the rapid development of facility horticulture, soilless cultivation technology and plug tray seedling technology are being promoted and applied on a large scale, which in turn promotes the research, development and application of cultivation substrates.

[0003] At present, the existing cultivation substrates are mainly granular bulk substrates, such as peat, perlite, vermiculite, etc. Granular bulk substrates have the problem of uncontrollable pore structure, which makes it difficult to achieve a balance between water retention and ventilation, and thus it is difficult for the substrate products to obtain good water retention and air permeability. In addition, as the planting process progresses, the pore structure of the bulk substrate will be deposited in the later stage, resulting in reduced ventilation and affecting crop growth.

[0004] Chinese patents "A plastic fiber culture soil and its preparation method" (application number CN105367216B) and "A solidifying matrix for three-dimensional cultivation and its preparation method" (application number CN106069685A) respectively disclose a plastic fiber culture soil and a solidifying matrix for three-dimensional cultivation. The raw materials of the culture soil or the solidifying matrix are fully heated in the mold, so that the hot-melt solidifying fibers therein are fully melted and bonded to each other, thereby bonding the matrix raw materials into a whole, thereby obtaining a solidified molding matrix with stable appearance and controllable microstructure. In addition, Chinese patents ZL 202011106363.5 (a matrix block with a hardened shell and a preparation device and a preparation method) and ZL 202011106377.7 (a microwave heating curing device, process and a solidifying matrix manufactured therefrom) respectively disclose two matrix curing processes and their devices. In the aforementioned patents, steam heating, microwave heating and other methods are used to heat the matrix raw materials and solidify them into shape. The entire matrix process includes loading, heating, solidification and molding, and demolding. However, there is currently no solidified matrix preparation device that can process and automate the four processes of loading, heating, solidification and molding, and discharging in one.

[0005] Therefore, an integrated solidification matrix preparation device is proposed. Utility Model Content

[0019] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , the utility model provides a technical solution:

[0021] An integrated solidified matrix preparation device comprises a loading station, a heating station, a solidification molding and discharging station, and a mold 201 position switching device, wherein the mold 201 position switching device comprises a rotating shaft 101 and a tray 102 connected to the rotating shaft 101, and three molds 201 are arranged on the tray 102, and the three molds 201 are distributed in a circular array, and the top of any mold 201 is open; the side wall and the bottom wall of any mold 201 are provided with a high-frequency induction heating coil 301.

[0022] In some implementations of this embodiment, the loading station is provided with a pressing plate 401 and a feeding funnel 501 adapted to the mold 201 from top to bottom, the feeding funnel 501 is located above the tray 102, and the feeding funnel 501 can be respectively connected to the three molds 201. The feeding funnel 501 has the same shape as the mold 201, is slightly smaller than the mold 201, and can be slightly extended into the mold 201.

[0023] In some implementations of this embodiment, the bottom plate 203 of the mold 201 is detachably connected to the mold 201, and the bottom plate 203 can move up and down in the mold 201, and a positioning hole 2031 is opened on the bottom plate 203; the curing, molding and unloading stations are provided with a molding heating platen 601 and a ejecting rod 701 adapted to the positioning hole 2031 from top to bottom. When any mold 201 moves to the curing, molding and unloading station, the mold 201 is located between the molding heating platen 601 and the ejecting rod 701.

[0024] In this embodiment, the heating method of the mold 201 uses high-frequency heating, which is a process of heating an object using a high-frequency electromagnetic field. Its working principle is to use a high-frequency electromagnetic field to generate an induced current inside the object, causing the object to heat up. The specific principle is as follows:

[0025] 1. High-frequency electromagnetic field generation: High-frequency electromagnetic waves are generated by a high-frequency generator, generally in the frequency range of 300kHz to 10MHz. High-frequency electromagnetic waves generate high-frequency magnetic fields through induction coils.

[0026] 2. High-frequency electromagnetic field propagation: Through electromagnetic induction, high-frequency electromagnetic fields generate induced currents on the surface of workpieces. Due to the characteristics of high-frequency electromagnetic waves, they can penetrate the surface of objects and enter the interior.

[0027] 3. Induction current generation: When high-frequency electromagnetic waves pass through an object, the conductor (such as metal) inside the object will be induced and generate an induced current. The magnitude of the induced current depends on the resistance of the object and the strength of the high-frequency electric field.

[0028] 4. Induced current heating: According to Joule's law, induced current produces a thermal effect inside an object. Specifically, the induced current multiplied by the resistance of the object generates heat that raises the temperature of the object.

[0029] The working principle of high-frequency heating can be applied to a variety of industries and fields, such as metal heating, plastic heating, matching, porcelain, etc. Compared with traditional heating methods, high-frequency heating has the advantages of fast heating speed, high efficiency and high precision. It can achieve local heating of objects, avoiding the problem of overheating or energy waste. In addition, high-frequency heating can also achieve precise control and steaming of objects by adjusting the frequency and power of the high-frequency electromagnetic field.

[0030] Since the high frequency heating induction coil cannot directly contact the object when heating the object, it needs to keep a certain distance from the object. After testing, the distance between the induction coil and the surface of the mold 201 is 0.5-1.5 cm, which is the best.

[0031] In some implementations of this embodiment, any mold 201 is a cylindrical structure, and a plurality of flanges 202 are provided at the bottom of any mold 201, and a bottom plate 203 is placed on the flanges 202. In this embodiment, the mold 201 is a rectangular parallelepiped structure, and in other embodiments, the mold 201 may also be a cylindrical structure.

[0032] In some implementations of this embodiment, a limiting column 801 is provided at the end of the ejector rod 701 close to the mold 201, and the diameter of the limiting column 801 is larger than the diameter of the positioning hole 2031. The limiting column 801 may be magnetic, and the stability of the connection between the ejector rod 701 and the bottom plate 203 is improved when the ejector rod 701 extends into the positioning hole 2031 to lift the bottom plate 203.

[0033] Working principle:

[0034] When preparing the matrix, the material is first added into the mold 201 located below the feeding funnel 501 through the feeding funnel 501. If necessary, the pressing plate 401 can be moved down to the opening of the mold 201 under the control of the corresponding control mechanism to press all the materials into the mold 201. Then the rotating shaft 101 rotates 120° under the control of the corresponding driving mechanism, so that the mold 201 containing the material is in the heating position, and then the high-frequency heating coil works to heat the bottom surface, side wall and molding heating plate 601 of the mold 201 containing the material. After the heating is completed, the rotating shaft 101 rotates 120° again, so that the mold 201 containing the material is in the curing molding and discharging position, and then the molding heating plate 601, which is also equipped with a high-frequency induction heating coil 301, moves downward under the control of the corresponding driving mechanism, and the molding heating plate 601 moves down to a certain depth in the mold 201, compresses the material in the mold 201 and keeps it for a certain time to heat and solidify it. Then the ejector pin 701 is inserted into the positioning hole 2031 and moves upward synchronously with the forming heating plate 601, so that the formed solidified matrix block is moved out of the mold 201. After the solidified matrix block is removed, the ejector pin 701 moves downward, and the bottom plate 203 moves downward to the bottom end of the mold 201 synchronously under the action of gravity or magnetic attraction. After the bottom plate 203 is blocked by the flange 202, the ejector pin 701 is separated from the bottom plate 203 and continues to move downward to the bottom of the corresponding heating coil, completing a complete preparation process. In actual production, the loading station, heating station, curing molding and unloading station work simultaneously, corresponding to the three preparation links of the solidified matrix, and the time required for each link is consistent, so as to continuously prepare the solidified matrix.

[0035] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field.
