Description

Technical Field

[0001] This utility model relates to the field of bioreactor equipment technology, and more specifically, to a magnetic coupling shearing device. Background Technology

[0002] In plant tissue culture, the culture and cutting of adventitious roots are crucial steps. As important materials for plant propagation and the production of secondary metabolites, the quality and integrity of adventitious roots are essential for subsequent research and applications.

[0003] Currently, adventitious roots are mostly cut manually or using traditional mechanical contact methods. Manual cutting requires operators to open the culture container in a clean bench and cut the adventitious roots one by one with scissors. This manual method is inefficient and prone to contamination and damage due to improper operation. Traditional mechanical contact cutting, on the other hand, directly contacts the adventitious roots, easily damaging them and affecting their activity and subsequent culture results. For ginseng adventitious roots inside culture bags, existing cutting methods are more likely to compromise the airtightness of the culture environment, increasing the risk of contamination. Utility Model Content

[0004] This invention provides a magnetic coupling shearing device, which aims to solve the problems of easy damage to adventitious roots, low efficiency, and high risk of contamination in existing adventitious root shearing methods.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a magnetic coupling shearing device, comprising a culture bag, wherein a built-in shearing seat is provided inside the culture bag, the built-in shearing seat is embedded with a magnetic element, the built-in shearing seat is provided with a plurality of arc-shaped blades, the cutting edges of the arc-shaped blades all facing away from the built-in shearing seat, the plurality of arc-shaped blades forming a mesh pattern, an external shearing seat is provided outside the culture bag, the external shearing seat is embedded with a magnetic element, the external shearing seat is provided with a magnetic force adjustment mechanism, and the arc-shaped blades on the built-in shearing seat and the end face of the external shearing seat can be magnetically attracted and abutted by the magnetic force of the magnetic element.

[0006] Furthermore, the magnetic force adjustment mechanism includes a magnetic force adjustment knob, which can control the magnetic force intensity.

[0007] Furthermore, the external shear seat is provided with a gripping part.

[0008] Furthermore, the end face of the external shear seat that abuts against the arc-shaped blade is a plane.

[0009] Furthermore, the curved blade is made of zirconia ceramic.

[0010] Furthermore, the arc-shaped blade and the built-in shearing seat are detachably connected via a snap-fit ​​structure.

[0011] Furthermore, the mesh diameter of the mesh pattern is 5-15mm.

[0012] Furthermore, the surface of the built-in shear seat is covered with a corrosion-resistant film.

[0013] Furthermore, both the built-in shear seat and the external shear seat have circular cross-sections, and both the built-in shear seat and the external shear seat have several embedded holes evenly distributed along their circumference inside, with the magnetic component disposed within the embedded holes.

[0014] Furthermore, the inner wall of the culture bag corresponding to the active area of ​​the arc-shaped blade is provided with a wear-resistant coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Non-contact magnetic transmission avoids mechanical damage. Combined with the sealed design of the culture bag, it can ensure a sterile environment during the shearing process, reduce the risk of contamination, avoid mechanical contact damage to adventitious roots, and ensure the integrity of adventitious roots.

[0017] 2. The device is flexible in operation, requires no complicated equipment, and is suitable for the cutting of adventitious roots in small culture bags, meeting the needs of small-scale culture.

[0018] 3. The curved blade is made of zirconia ceramic material. Zirconia ceramic blade is wear-resistant, corrosion-resistant, and has a smooth surface that does not easily attract organic matter. In addition, ceramic has good biocompatibility, which can avoid the contamination of adventitious roots by metal rust and ensure the quality of adventitious roots. It is especially suitable for the cultivation of medicinal plants such as ginseng adventitious roots.

[0019] 4. The external shearing seat is equipped with a magnetic force adjustment mechanism, which can adjust the magnetic force intensity according to the thickness and toughness of the adventitious root, so as to avoid the internal shearing seat moving too fast and damaging the adventitious root due to excessive magnetic force, or the magnetic force being too weak to effectively drive the blade to cut.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, this utility model discloses a magnetic coupling shearing device, including a culture bag, which is a transparent sterile plastic bag with a sealed opening to ensure a sterile internal environment. The culture bag contains ginseng adventitious roots and an internal shearing seat 100. The internal shearing seat 100 is flat and circular for easy movement within the culture bag. The surface of the internal shearing seat 100 is covered with a corrosion-resistant film, and a magnetic component is embedded within it. Multiple arc-shaped blades 101 are provided on the internal shearing seat 100. The cutting edges of the arc-shaped blades 101 all face away from the internal shearing seat 100 and form a 90° angle with the surface of the internal shearing seat 100. The arc-shaped blades 101 are staggered and form a mesh pattern. The mesh openings 102 of the mesh pattern have a diameter of 8 mm.

[0031] An external shearing seat 200 is provided outside the culture bag. The external shearing seat 200 is equipped with a magnetic component and a magnetic force adjustment mechanism that can adjust the magnetic force intensity. The arc-shaped blade 101 on the internal shearing seat 100 and the end face of the external shearing seat 200 are attracted and abutted by the magnetic force of the magnetic body inside them, thereby shearing the adventitious roots.

[0032] The working process of the device is as follows: Ginseng adventitious roots are placed in a culture bag, and the built-in shearing seat 100 is placed in the bag. The culture bag is sealed by the sealing structure at the bag opening. The operator holds the external shearing seat 200 and adjusts the magnetic strength according to the thickness and toughness of the ginseng adventitious roots through the magnetic adjustment mechanism. The magnetic force on the external shearing seat 200 attracts the built-in shearing seat 100 to move inside the culture bag. The arc-shaped blade 101 on the built-in shearing seat 100 moves with it. The mesh structure and the sharp arc-shaped blade 101 cut the ginseng adventitious roots from multiple directions, reducing pulling damage. After the cutting is completed, the external shearing seat 200 is removed.

[0033] The aforementioned magnetic force adjustment mechanism includes a magnetic force adjustment knob 201, which can control the magnetic force intensity. Operators only need to rotate the magnetic force adjustment knob 201 to control the magnetic force intensity, making operation simple.

[0034] The aforementioned arc-shaped blade 101 is made of zirconia ceramic material. The arc-shaped blade 101 made of zirconia ceramic material is wear-resistant, corrosion-resistant, and has a smooth surface that does not easily adhere to organic matter, reducing the accumulation of residue after shearing and reducing the difficulty of cleaning. In addition, ceramic has good biocompatibility, further ensuring the biological activity of adventitious roots.

[0035] Both the built-in shear seat 100 and the external shear seat 200 have circular cross-sections. Both the built-in shear seat 100 and the external shear seat 200 have several circumferentially distributed embedding holes 203 inside, and the magnetic components are installed in the embedding holes 203.

[0036] The aforementioned external shearing seat 200 is provided with a gripping part 202, which makes it easy for operators to grip the external shearing seat 200 to perform shearing of adventitious roots.

[0037] The end face of the external shear seat 200 that abuts against the arc-shaped blade 101 is a plane, and the area of ​​the plane end face is adapted to the projected area of ​​the arc-shaped surface formed by the arc-shaped blade 101.

[0038] The aforementioned arc-shaped blade 101 is detachably connected to the built-in shearing seat 100 via a snap-fit ​​structure. When the arc-shaped blade 101 is worn or damaged, it can be easily replaced, reducing the cost of use.

[0039] The aforementioned arc-shaped blade 101 and the built-in shear seat 100 are integrally injection molded. The integrated structure can reduce the number of parts and reduce assembly steps.

[0040] The surface of the built-in shear seat 100 is covered with a corrosion-resistant film. This film can prevent corrosive substances that may be generated on the surface of the built-in shear seat 100 from penetrating into the culture environment, thus avoiding quality degradation caused by contamination.

[0041] Both the built-in shear seat 100 and the external shear seat 200 have circular cross-sections. Both the built-in shear seat 100 and the external shear seat 200 have several embedded holes 203 evenly distributed along their circumference inside. The magnetic component is disposed in the embedded hole 203.

[0042] The inner wall of the culture bag corresponding to the active area of ​​the arc-shaped blade 101 is provided with a wear-resistant coating, which enhances the scratch resistance of the corresponding area and extends the service life of the culture bag.

[0043] The built-in shearing unit 100 includes a built-in top cover 110 and a built-in base 120, which are detachably connected. An arc-shaped blade 101 is disposed on the built-in top cover 110. The external shearing unit 200 includes an external top cover 210 and an external base 220, which are detachably connected. A gripping part 202 and a magnetic adjustment knob 201 are both disposed on the external top cover 210.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
