[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0037] like Figures 1 to 6 As shown, the embodiment of the present invention provides a packaging device for laboratory plant culture medium, including a machine base 1, a culture dish carrier 2, a push-pull mechanism 3, a lifting mechanism 4, a lifting and heat-sealing mechanism 5, a film roll 6 and a film traction mechanism 7;

[0038] The base 1 is provided with a support frame 10, the lifting and heat-sealing mechanism 5 is provided on the top of the support frame 10, and the push-pull mechanism 3 is provided at the bottom of the support frame 10. The push-pull mechanism 3 is connected to the culture dish carrier 2 to push the culture dish carrier 2 to move toward or away from the bottom of the lifting and heat-sealing mechanism 5. The culture dish carrier 2 is provided with a plurality of accommodating holes 20 for placing culture dishes, and the top edges of the accommodating holes 20 are provided with positioning ring grooves 201, and the positioning ring grooves 201 are used to position and engage with the dish mouths of the culture dishes; the accommodating holes 20 on the culture dish carrier 2 can position the culture dishes, and the setting of the positioning ring grooves 201 can prevent the culture dishes from shaking or shifting during the packaging process, thereby improving the packaging accuracy; when the packaging operation is required, the push-pull mechanism 3 can accurately move the culture dish carrier 2 to the area below the lifting and heat-sealing mechanism 5, so that the lifting and heat-sealing mechanism 5 can perform packaging processing on the culture dishes.

[0039] The lifting mechanism 4 is located on the machine base 1 below the accommodating hole 20. The lifting mechanism 4 is used to push the heat-sealed culture dish upward from the accommodating hole 20. When the packaging is completed, the culture dish can be pushed upward by the lifting mechanism 4, reducing the tedious operation of manual removal and improving operational efficiency.

[0040] The film roll 6 is mounted at one end of the support frame 10, and the film pulling mechanism 7 is mounted at the other end of the support frame 10. The film pulling mechanism 7 is used to pull out the film wound on the film roll 6. The lifting and heat sealing mechanism 5 is used to heat-seal the pulled out film onto the culture dish on the culture dish carrier 2. The film pulling mechanism 7 can pull the film wound on the film roll 6 to the packaging position, thereby achieving a continuous supply of film and improving the efficiency of the packaging operation.

[0041] like Figure 4 As shown, the push-pull mechanism 3 further includes side baffles 31 and a push-pull cylinder 32. The two side baffles 31 are respectively provided on both sides of the culture dish carrier 2. The side baffles 31 are provided with a limiting slide 310. The end of the culture dish carrier 2 is provided in the limiting slide 310. The movable end of the push-pull cylinder 32 is connected to the culture dish carrier 2 to drive the culture dish carrier 2 to slide along the extension direction of the limiting slide 310. The provision of the limiting slide 310 can prevent the culture dish carrier 2 from shifting during movement. When it is necessary to replace culture medium of different specifications to cultivate different types of plants, the user can pull the culture dish carrier 2 out of the limiting slide 310 to quickly replace it with a new one, which is practical and convenient.

[0042] like Figure 1 and Figure 4As shown, the lifting mechanism 4 further includes a lifting seat 41, a lifting rod 42, and a lifting cylinder 43. The lifting cylinder 43 is arranged inside the machine base 1. The movable end of the lifting cylinder 43 is arranged upward and is connected to the lifting rod 42. The top of the lifting rod 42 is connected to the bottom of the lifting seat 41 through a threaded connection. The lifting seat 41 is used to lift the culture dish upward with the lifting action of the lifting cylinder 43. When the culture dish completes the packaging operation, the lifting cylinder 43 can drive the lifting seat 41 to move upward through the lifting rod 42 to eject the culture dish from the accommodating hole 20, thereby realizing rapid material retrieval.

[0043] like Figure 3 As shown, the device further includes several guide rollers 8, which are installed on the support frame 10 on both sides below the lifting and heat sealing mechanism 5. The guide rollers 8 are used to abut against the upper surface of the film and guide it to be transported in a different direction. The provision of the guide rollers 8 ensures smooth film transportation during the packaging process and maintains appropriate tension on the film to prevent wrinkles or deviation of the film.

[0044] like Figure 5 and Figure 6 As shown, further, the lifting heat sealing mechanism 5 includes a lifting cylinder 51, a lifting plate 52, a die seat 53 and a heating tube 54.

Several die seats 53 are connected to the lifting plate 52 through a first spring pin 55. The heating tube 54 is arranged in the die seat 53. The heating tube 54 is used to heat the die seat 53. The die seat 53 is used to heat the film on the mouth of the culture dish as the lifting cylinder 51 moves up and down. When the mouth of the culture dish needs to be sealed, the lifting cylinder 51 can drive the die holder 53 to descend and contact the edge of the mouth of the culture dish. Under the action of the heating tube 54, the die holder 53 fuses the film with the mouth of the culture dish to complete the heat seal. The setting of the first spring pin 55 can prevent the die holder 53 from causing pressure loss to the culture dish during sealing. The entire culture dish sealing process is automated, eliminating the tedious operation of manual intervention.

[0045] like Figure 5 As shown, further, a lower pressure ring 56 adapted to the shape of the dish mouth of the culture dish is provided at the bottom of the die seat 53, and an annular cutter 57 is provided on the peripheral wall of the lower pressure ring 56; the setting of the lower pressure ring 56 can make the pressure during packaging more uniform and concentrated, thereby improving the tightness of the packaging; the annular cutter 57 can cut off the excess film covering the edge of the dish mouth, making the sealing edge more neat.

[0046] like Figure 5As shown, the device further includes a buffer plate 58 connected to the lifting plate 52 via a second spring pin 59. A central portion of the buffer plate 58 is provided with an escape groove for the upward and downward movement of the die holder 53. The buffer plate 58 can abut against the culture dish carrier 2 as the die holder 53 descends, thereby reducing direct pressure on the culture dish and preventing damage to the dish caused by excessive pressure.

[0047] like Figure 2 and Figure 3 As shown, further, the film traction mechanism 7 includes a reduction motor 71 and a film winding shaft 72, the output shaft of the reduction motor 71 is connected to the film winding shaft 72, and the film winding shaft 72 is provided with a film winding disc 73, and the film winding disc 73 is connected to the film winding shaft 72 by bolt locking, and the film winding disc 73 is used to wind and collect the waste film as the film winding shaft 72 rotates. In this way, the automatic collection of waste film can be realized, the tediousness of frequent manual cleaning is reduced, the continuous operation of the packaging equipment is ensured, and the packaging efficiency of the culture dish is improved.

[0048] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
