Description

Technical Field

[0001] The utility model relates to the field of preparation of edible and medicinal fungus culture medium, in particular to a film covering mechanism for a culture medium material basin. Background Art

[0002] Cordyceps flower, also known as northern cordyceps and cordyceps militaris, has certain similarities in ingredients with Cordyceps sinensis. Cordyceps flower is listed as one of the three major tonics in China along with ginseng and deer antler. In addition, as a precious edible and medicinal fungus, the optimization of its production process has always been a hot topic in industry research against the background of the rapid development of modern agricultural science and technology.

[0003] The production process of Cordyceps flower includes the preparation of cultivated varieties → preparation of culture medium → sterilization and inoculation → shelf germination → grass management → harvesting → storage. In the prior art, the production process of Cordyceps flower culture medium is mainly based on the combination of manual labor and labor tools. After the solid and liquid materials are filled into the culture medium basin, the culture medium basin needs to be sealed by coating before the "sterilization and inoculation" and other processes can be carried out. The coating process of the culture medium basin in the prior art is mainly completed manually, which is not only labor-intensive but also has relatively low production efficiency.

[0004] The Chinese utility model patent with the authorization announcement number CN208987445U discloses a film-type automatic bagging machine suitable for edible fungus culture medium. The device uses a film suction mechanism to suck the packaging film. The film suction mechanism includes a vertically arranged film suction head and a film suction cylinder for driving the film suction head to move left and right. The film suction head is equipped with a vacuum suction cup for sucking the packaging film and an edge sealer for sealing the packaging film. The film suction cylinder is used to drive the film suction head to move left and right, and then the sucked packaging film is merged into a bag at the feeding pipe. However, the device is not suitable for the film coating process of the Cordyceps flower culture medium pot. Due to the production process requirements, the Cordyceps flower culture medium pot only needs to be coated at the open end and then sealed by an elastic leather sleeve. It does not need to combine the film into a bag. In addition, since the solid material and liquid material ratio of the Cordyceps flower culture medium have strict requirements, the volume size of the culture medium pot is also strictly required. At the same time, the Cordyceps flower culture medium pot has a variety of specifications, so it is also necessary to accurately control the coverage area of ​​the film to meet the film coating requirements of culture medium pots of different specifications and sizes.

[0005] The Chinese invention patent with the publication number CN111204493A discloses an automatic film packaging machine for culture medium production, and the filming process is as follows: in the filming section, the heat shrink film is first manually loaded into the circular guide cylinder and becomes a round sleeve shape, and then the heat shrink film is loaded into the guide cylinder to be flush with its bottom, and the clamping manipulator grips the guide cylinder and moves downward, falls on the top surface of the positioning cylinder, and is aligned with the center of the positioning cylinder by the conical surface positioning guide. Subsequently, the manipulator claw is slightly loosened to a semi-tight state, and continues to move vertically downward. The heat shrink film slides downward along the outer surface of the positioning cylinder driven by the manipulator claw, and stops sliding down after reaching the preset position. The action of this device is similar to that of the CN208987445U patent, and the only difference is that this device uses structures such as manipulators and guide cylinders to form a bag-shaped film and put it on the culture medium vessel. This device is also not suitable for the filming operation of the Cordyceps flower culture medium material pot. Utility Model Content

When the utility model starts working, the culture medium basin is transported to the film coating station below the film pressing assembly 2 through the transmission line 5, and then the film is drawn out from the film roller 101 and covered on the upper opening of the culture medium basin. At the same time, the head end of the film is clamped and fixed by the upper clamping plate 4011 and the lower clamping plate 4012 of the film-drawing clamping plate cylinder 401, and then the transmission line 5 is started to drive the culture medium basin to move out of the film coating station. At the same time, the film-drawing clamping plate cylinder 401 moves synchronously with the transmission line 5 to draw the film. In this way, when the culture medium basin moves to the next set station, its upper opening is still covered by the film. In addition, during the movement of the culture medium basin, the film pressing plate 202 in the film pressing assembly 2 is in a descending state. In this way, when the culture medium basin moves, the film on its upper end can be completely covered on the basin through the pressing effect of the film pressing plate 202. At this time, the film cutting knife 301 in the film cutting assembly 3 moves to one side of the transmission line 5 and does not affect the movement of the culture medium basin and the film. When the culture medium basin is moved into place, Figure 6 As shown, at this time, the film cutting knife 301 can move horizontally in the left and right directions to cut and separate the film covering the material basin from the subsequent films, and then the film cutting knife 301 moves back to the side of the transmission line 5, and the upper clamping plate 4011 and the lower clamping plate 4012 of the film pulling clamping cylinder 401 open and return to their original positions. At this time, the culture medium material basin that has completed the film coating is driven by the transmission line 5 into the leather cover fitting station to complete the film covering and fixing process. At the same time, the next culture medium material basin re-enters the film coating station and props up the head end of the new film formed after film cutting. At this time, Figure 2 As shown, the film-pulling clamping plate cylinder 401 retracts one end of the film-cutting assembly 3, so that the upper clamping plate 4011 and the lower clamping plate 4012 of the film-pulling clamping plate cylinder 401 can clamp the new film head again and repeat the above process, that is, the transmission line 5 starts to drive the culture medium material basin to the next station, and at the same time, the film-pulling clamping plate cylinder 401 cooperates to move and continue to pull out the film, and when the material basin and the film move, the film pressing plate 202 in the film pressing assembly 2 descends to press the film tightly on the upper opening of the material basin, and when the culture medium material basin moves into place, the film cutting knife 301 in the film cutting assembly 3 moves horizontally again to cut the film.

The utility model adopts a screw nut structure to drive the film pulling clamp cylinder 401 to move, which can accurately control the moving distance of the film head end, thereby ensuring that the film area covering the opening of the culture medium basin meets the requirements. At the same time, the moving distance can be flexibly adjusted according to the different volume specifications of the culture medium basin, that is, the coating area can be flexibly adjusted. In addition, the film cutting knife 301 and the film pressing plate 202 also have sufficient lateral moving distance and film pressing length to meet the coating needs of culture medium basins of different specifications.

[0040] The working principle of the utility model is:

[0041] When the utility model starts working, the culture medium basin is transported to the coating station below the film pressing assembly 2 through the transmission line 5, and then the film is drawn out from the film roller 101 and covered on the upper opening of the culture medium basin. At the same time, the head end of the film is clamped and fixed by the upper clamping plate 4011 and the lower clamping plate 4012 of the film pulling clamping cylinder 401. Then the transmission line 5 starts to drive the culture medium basin to move out of the coating station. At the same time, the film pulling clamping cylinder 401 moves synchronously with the transmission line 5 to pull out the film, and during the movement of the culture medium basin, the film pressing plate 202 in the film pressing assembly 2 is in a descending state to ensure that the film is pressed tightly.
