Description

Technical Field

[0001] The present invention relates to the field of mushroom preparation, and particularly to a sterile bag-making device. Background Art

[0002] When cultivating edible mushrooms, the following steps are generally included:

[0003] Select appropriate raw and auxiliary materials, such as rice straw, wood chips, etc., and perform appropriate stirring and mixing to form a substrate required for cultivating edible mushrooms.

[0004] Substrate preheating: Preheat the substrate to an appropriate temperature through a heating device to prepare for the subsequent sterilization process.

[0005] Substrate feeding: Load the preheated substrate into a specially designed strain tank. The strain tank is divided into four independent chambers, namely a heating chamber, a pre-cooling chamber, a cooling chamber, and a seed mixing chamber.

[0006] Substrate sterilization: The substrate is conveyed to the heating chamber and sterilized at high temperature by steam, heating the substrate to about 126 degrees to kill possible pathogenic microorganisms and harmful strains.

[0007] Substrate cooling: The sterilized substrate will be sent to the pre-cooling chamber and the cooling chamber for temperature reduction, and finally the substrate is cooled to about 20 degrees. This is to ensure that the subsequently added edible mushroom strains grow at an appropriate temperature.

[0008] Inoculation: The cooled substrate enters the seed mixing chamber, where the addition and mixing of strains are carried out, that is, the inoculation process.

[0009] Sterile bag-making: The inoculated substrate is discharged and packaged in a strictly sterile environment to prevent the substrate that has been sterilized at high temperature from being contaminated by new microorganisms, ensuring the pure cultivation of edible mushrooms.

[0010] The device for loading the seed-mixed substrate into a container (usually a plastic bag) is usually called a filling machine or a bagging machine. This is a special automated device that can accurately fill the substrate into a preset container and seal the container for subsequent cultivation.

[0011] The working principle of such a bagging machine is usually as follows: First, the pre-prepared empty bag is placed at the discharge port of the bagging machine, then the bagging machine injects a preset amount of seed-mixed substrate into the bag, and finally seals the bag mouth. This process can be fully automatic or semi-automatic, that is, manual placement and removal of the bag are required.

[0012] In the production of edible fungi, since it is necessary to maintain a sterile environment, the bagging machine is usually designed to be enclosed. The interior of the bagging machine maintains a sterile environment, and the bagging operation is carried out inside the enclosed bagging machine, avoiding the pollution of the fungus bags by the external environment. This can greatly improve the quality and production efficiency of the fungus bags.

[0013] Although the bagging machine plays an important role in the production of edible fungi, there are still some problems with this equipment at present:

[0014] The manufacturing and maintenance costs of automatic bagging machines are relatively high, and the structure is very complex, which may make it unaffordable for smaller edible fungi producers;

[0015] Although the bagging machine can achieve automatic bagging, the setting and debugging of the equipment may require professional knowledge, and it may malfunction during daily operation, requiring professional personnel for repair;

[0016] During the production process, the interior of the bagging machine needs to maintain a sterile environment, which requires regular cleaning and disinfection of the bagging machine. However, the design and structure of the bagging machine may make the cleaning and disinfection work difficult;

[0017] Finally, since the matrix material after seed dressing needs to be output from the seed tank, then transported and input into the bagging machine, and then aseptic bag making is carried out, this method requires additional transportation, and the transportation process is prone to the entry of seeds, increasing the exposure situation. Summary of the Invention

[0018] To solve the above problems, the present invention provides an aseptic bag making device, which can complete the aseptic bag making action with the help of a seed tank, does not require an automatic bagging machine, does not require intermediate transportation, and can use the stirring mechanism in the seed tank as the filling power source, simplifying the structure. The whole process is sealed and sterile, and has the functions of pressing and positioning and automatic cutting, reducing the economic cost and effectively solving the deficiencies in the prior art.

[0019] The present invention is realized through the following technical solutions: An aseptic bag making device, including a machine table, which has a sterile temporary storage cavity inside. A seed tank is installed on the machine table, and the seed tank has a plurality of processing cavities and a seed dressing cavity;

[0020] A docking box, which is arranged on both sides of the seed dressing cavity of the machine table. The docking box has a feeding cavity inside, and one side of the feeding cavity is communicated with the seed dressing cavity;

[0021] A bag making box, which is respectively arranged at the bottom of the docking box. A bag making mechanism is arranged inside the bag making box, and the input end of the bag making mechanism is connected and communicated with the feeding cavity of the docking box;

[0022] A discharge pipe, one end of which is connected to the output end of the bag making box, and the other end of the discharge pipe is communicated with the sterile temporary storage cavity inside the machine table;

[0023] A stirring mechanism is arranged in the seed dressing cavity. After the matrix material is dressed with seeds, the stirring mechanism in the seed dressing cavity outputs it into the packaging box, and aseptic packaging is carried out by the packaging mechanism.

[0024] As a preferred technical solution, there is a packaging cavity with an open top in the packaging box. The packaging cavity is hermetically docked with the docking box, and the packaging mechanism is arranged at the open position at the top of the packaging cavity.

[0026] As a preferred technical solution, the packaging bag roll is wound by a bearing layer and packaging bags arranged at equal intervals on the bearing layer. Each packaging bag has a bag ring. The bag ring is connected to the bearing layer through a tear line. Pulling rings are also arranged on both sides of the bag ring. A tightening belt is arranged in the bag ring and is connected to the pulling ring. The outer end of the pulling ring is integrally connected to the bearing layer. A first recessed groove for yielding is arranged on the bearing layer corresponding to the pulling ring. The pulling ring extends into the first recessed groove and is connected to the bearing layer.

[0027] As a preferred technical solution, a pressing mechanism is arranged in the packaging cavity on both sides of the first recessed groove for yielding. Cutting mechanisms are arranged at positions corresponding to the pulling rings on the pressing mechanisms. The pressing mechanisms are linked with the stirring mechanism in the seed dressing cavity. When the stirring mechanism makes a stirring action, the bearing layer is pressed against the lower end surface of the docking box by the linkage of the pressing mechanisms. At this time, the feeding port of one of the packaging bags of the packaging bag roll corresponds to the discharging port at the output end of the docking box. After the matrix material is dressed with seeds, it is input into the packaging bag through the stirring mechanism for aseptic packaging.

[0028] As a preferred technical solution, the pressing mechanisms all include an "L"-shaped fixing plate. An air storage bag is arranged on the fixing plate. A pressing plate is installed on the top of the air storage bag. The air storage bag is connected to the extrusion driving mechanism in the stirring mechanism through a connecting pipe for air conduction. When the stirring mechanism stirs, the extrusion driving mechanism extrudes gas into the air storage bag and makes the air storage bag expand. At this time, the pressing plate always presses the bearing layer of the packaging bag roll against the lower end surface of the docking box. The cutting mechanism is arranged in the fixing plate and is located on one side of the pulling ring. When the gas in the air storage bag returns to the extrusion driving mechanism, the pressing plate resets through the air storage bag. At this time, the cutting mechanism pops out to cut off the pulling ring.

[0029] As a preferred technical solution, one end of the air storage bag is fixedly bonded to the fixing plate, and the other end is fixedly bonded to the pressing plate. The air storage bag is made of an elastic rubber material with the ability to recover deformation and expands after being filled with gas from the extrusion driving mechanism;

[0030] Each of the cutting mechanisms includes a cutting blade, the cutting blade is inserted into a blade installation groove opened on a fixing plate, a second recess is opened at a position corresponding to the cutting blade on the air storage bag, at least two telescopic tubes are arranged in the first and second recesses, a telescopic driving tube is arranged at the bottom surface of the blade installation groove, each telescopic driving tube corresponds to one telescopic tube, and the telescopic tube is connected and communicated with the telescopic driving tube.

[0031] As a preferred technical solution, the telescopic tube includes a telescopic connecting rod and a fixed sleeve, one end of the telescopic connecting rod is connected to a pressing plate, the other end extends into the fixed sleeve, a telescopic sealing plug is arranged at the extending end, the telescopic sealing plug seals the fixed sleeve, and one end of the fixed sleeve is fixedly inserted into the telescopic driving tube and is connected and communicated with the telescopic driving tube;

[0032] The telescopic driving tube includes a driving fixed tube and a driving movable rod, one end of the driving fixed tube is fixedly installed on the bottom surface of the blade installation groove, one end of the driving movable rod is inserted into the driving fixed tube and a driving sealing plug is arranged at the extending end, the other end of the driving movable rod is connected to the cutting blade, an air inlet and outlet cavity is formed in the driving fixed tube, the air inlet and outlet cavity is connected and communicated with the telescopic tube, when the telescopic connecting rod is inserted into the fixed sleeve, the gas in the fixed sleeve enters the air inlet and outlet cavity and pushes out the driving movable rod, and then pushes out the cutting blade;

[0033] A connecting spring is also fixedly arranged on the bottom surface of the blade installation groove, the other side of the connecting spring is fixedly connected to the end face of the inserting end of the cutting blade, and the cutting blade is retracted into the blade installation groove through the connecting spring.

[0034] As a preferred technical solution, the stirring mechanism includes a driving motor, a driving motor shaft, and stirring blades, the extrusion driving mechanism is installed at the farthest end of the driving motor shaft from the driving motor, the stirring blades are installed on the driving motor shaft, and the end of the driving motor shaft is installed on a support bearing;

[0035] The extrusion driving mechanism includes a cam extrusion block installed on the driving motor shaft, the cam extrusion block is rotatably installed in a cam installation groove, an extrusion air bag is arranged at the bottom surface of the cam installation groove, the extrusion air bag is connected and communicated with the air storage bag through a connecting pipe, and the gas in the extrusion air bag is continuously squeezed into the air storage bag through the rotation of the cam extrusion block, and the air storage bag is inflated.

[0036] As a preferred technical solution, a control panel is further arranged on the machine table, and control buttons are arranged on the control panel.

[0037] The beneficial effects of the present invention are as follows: The present invention ingeniously uses the stirring mechanism in the strain tank as the power source in the aseptic bag-making stage. This design does not require additional power equipment, thus greatly simplifying the overall structure. After the mixing of the strain and the substrate, the stirring process can directly discharge the materials, realizing continuous aseptic bag-making. Since the substrate does not need to be transported during the whole process, the contact opportunities with the external environment and possible bacteria are greatly reduced.

[0038] The invention uses an internal strain tank to achieve aseptic bag-making, thus avoiding the need for a dedicated external aseptic bag-making environment. This not only ensures aseptic conditions but also greatly reduces production costs, achieving a better integration effect.

[0039] Since the present invention does not rely on an external bagging machine for aseptic bag-making, the operating costs are greatly reduced. At the same time, by realizing the mixing of the substrate, aseptic bag-making, and collection after bag-making in the strain tank, the overall structure is greatly simplified.

[0040] The present invention ingeniously utilizes the weight of the substrate after bag-making and combines it with an innovative design of the bag roll structure for the bag to be made, enabling the automatic cutting, blanking, and collection of the packaging bag and the bearing layer after separation. This design improves the degree of automation, reduces manual intervention, and effectively reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any manner.

[0059] Any feature disclosed in this specification (including any appended claims, abstract and drawings) may be replaced by other equivalent or similar features with a similar purpose, unless specifically recited. That is, unless specifically recited, each feature is only an example of a series of equivalent or similar features.

[0060] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by terms such as "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "central", "end", "length", "outer end", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation on the present invention.

[0061] In addition, in the description of the present invention, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0062] Spatial relative position terms such as "upper", "above", "lower", "below", etc. used in the present invention are for the purpose of facilitating the description of the relationship between one unit or feature and another unit or feature as shown in the drawings. The spatial relative position terms may be intended to include different orientations of the device in use or operation other than the orientation shown in the drawings.

[0063] In the present invention, unless otherwise clearly specified and defined, terms such as "arranged", "socketed", "connected", "penetrated", "plugged in", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention may be understood according to specific circumstances.

[0064] Such as Figures 1 - 6As shown in the figure, a sterile packaging equipment of the present invention includes a machine table 3. There is a sterile temporary storage cavity 15 inside the machine table 3. A strain tank 1 is installed on the machine table 3. There are multiple processing cavities and a seed dressing cavity 12 inside the strain tank 1. The multiple processing cavities can be a heating cavity, a pre-cooling cavity, and a cooling cavity arranged in sequence. Finally, the processed substrate enters the seed dressing cavity 12 for seed dressing operation;

[0065] It further includes a docking box 6, which is arranged on both sides of the seed dressing cavity 12 of the machine table 3. There is a feeding cavity 16 inside the docking box 6. One side of the feeding cavity 16 is communicated with the seed dressing cavity 12. The substrate in the seed dressing cavity 12 can enter the feeding cavity 16 by stirring;

[0066] It further includes a packaging box 8, which is respectively arranged at the bottom of the docking box 6. A packaging mechanism is arranged inside the packaging box 8. The input end of the packaging mechanism is in butt joint and conduction with the feeding cavity 16 of the docking box 6. As Figure 4 shown in Figure 5 the figure, the substrate entering the feeding cavity 16 through stirring can enter the packaging box 8 for packaging action, achieving the purpose of sterile packaging. The packaging box 8 is internally communicated with the strain tank 1, so it is also in a closed and sterile environment. In this way, the substrate discharged from the strain tank 1 can immediately enter the packaging box 8 to achieve the purpose of packaging;

[0067] In order to output and temporarily store the packaged strain packages, it further includes a discharge pipe 10. One end of the discharge pipe 10 is butt-jointed with the output end of the packaging box 8, and the other end of the discharge pipe 10 is communicated with the sterile temporary storage cavity 15 inside the machine table 3. The packaged strain packages will be output through the discharge tank to the sterile temporary storage cavity 15 inside the machine table 3 for storage. After the strain packaging is completed, they can be uniformly moved to the cultivation cavity for cultivation;

[0068] In order to realize seed dressing, a stirring mechanism is also arranged inside the strain tank 1. The stirring mechanism is arranged in the seed dressing cavity 12. The stirred substrate material after seed dressing is output into the packaging box 8 through the stirring mechanism in the seed dressing cavity 12 and is subjected to sterile packaging through the packaging mechanism. The stirring mechanism can be used for both seed dressing of the strain and the substrate, and can also use the stirring mechanism to discharge the stirred substrate material into the packaging box 8. The sterile packaging action is carried out through the packaging bag inside the packaging box 8. Therefore, this structure completely eliminates the use of a bagging machine, can greatly save economic costs, simplifies the structure, and is integrally formed without intermediate transfer and transportation.

[0069] Among them, there is a packaging cavity 25 with an open top inside the packaging box 8. The packaging cavity 25 is hermetically butted with the docking box 6, and the packaging mechanism is arranged at the open top position of the packaging cavity 25. When the substrate in the docking box 6 is driven into the packaging box 8 through the stirring mechanism, it just falls into the packaging mechanism for packaging.

[0070] The bag-making mechanism includes a roll material roller 21, a material receiving roller 20, and a bag-making bag roll wound around the roll material roller 21. A winding motor 5 is arranged outside the material receiving roller 20. The roll material roller 21 is used to wind the bag-making bag roll at the upper end, and then the winding motor 5 works. The material receiving roller 20 is used to receive the material, and the bag-making bag roll on the roll material roller 21 is actively wound. Therefore, the purpose of discharging and receiving materials at the same time is achieved. Since a large number of packaging bags can be wound on the roll material roller 21, there is no need to open and install packaging bags in the middle, ensuring continuous aseptic bag-making, and effectively solving the problems of material receiving and feeding.

[0071] As Figure 7 and Figure 9 shown, the bag-making bag roll is wound by a bearing layer 19 and packaging bags arranged equidistantly on the bearing layer 19. Each packaging bag has a bag ring 29, and the bag ring 29 and the bearing layer 19 are connected by a tear line 27. Pulling rings 28 are arranged on both sides of the bag ring 29. A tightening belt is arranged inside the bag ring 29, and the tightening belt is connected to the pulling rings 28. The outer end of the pulling ring 28 is integrally connected to the bearing layer 19. A first recessed groove 26 is arranged on the bearing layer 19 corresponding to the pulling ring 28. As Figure 8 shown, the pulling ring 28 extends into the first recessed groove 26 and is connected to the bearing layer 19. When not in packaging, the packaging bag is pulled out from the roll material roller 21. As Figure 7 shown by the first packaging bag 22, before the first packaging bag 22 is filled, it is in a contracted state and has no filling. The first packaging bag 22 here is actually a packaging bag in an unfilled state. Then, the packaging bag at the filling position, that is, the second packaging bag 23, has its opening facing the discharge port 17, and the matrix material stirred and output by the stirring mechanism will enter the second packaging bag 23. As the weight continuously increases, the mass of the second packaging bag 23 becomes larger and larger, and the tear line 27 between the bag ring 29 and the bearing layer 19 breaks. At this time, since the pulling ring 28 is still connected to the bearing layer 19, when the second packaging bag 23 after the whole bag-making is completed separates from the bearing layer 19 at the bag ring 29, the whole packaging bag drops downward. During this process, since the pulling ring 28 is connected to the bearing layer 19, the weight of the second packaging bag 23 can be used to pull and tighten the tightening belt, achieving the purpose of sealing the top of the packaging bag. As Figure 14 shown, at this time, the whole second packaging bag 23 after the bag-making is completed hangs at the bottom, waiting for the next operation. When arranging the bag-making bag roll, it needs to be disinfected as a whole to ensure that there are no other bacteria in the whole bag-making box 8.

[0072] As Figure 9 and Figure 10As shown, in order to support the second packaging bag 23 after bag making is completed and to achieve better docking and positioning of the second packaging bag 23 during the bag making process, in this embodiment, a pressing mechanism 18 is provided in the bag making cavity 25 on both sides of the first retraction groove 26. A cutting mechanism is provided at a position corresponding to the draw ring 28 on the pressing mechanism 18. The pressing mechanism 18 is linked with the stirring mechanism in the seed dressing cavity 12. When the stirring mechanism performs a stirring action, the pressing mechanism 18 is linked to press the bearing layer 19 against the lower end surface of the docking box 6. At this time, the feeding port of one of the packaging bags of the packaging bag roll corresponds to the discharging port 17 at the output end of the docking box 6. The matrix material after seed dressing is input into the packaging bag through the stirring mechanism for aseptic bag making. Therefore, the pressing mechanism 18 is very important. Without the pressing mechanism 18, the entire bag ring 29 will be pulled down by the weight, making it difficult for the feeding port of the packaging bag to correspond to the discharging port 17. Therefore, after the bag ring 29 is pressed by the pressing mechanism 18, close-range tight filling can be achieved.

[0073] As Figure 11 and Figure 12 As shown, the pressing mechanism 18 includes an "L"-shaped fixing plate 181. An air storage bag 182 is provided on the fixing plate 181. A pressing plate 184 is installed at the top of the air storage bag 182. The air storage bag 182 is connected for air conduction with an extrusion driving mechanism 11 in the stirring mechanism through a connecting pipe 4. When the stirring mechanism stirs, the extrusion driving mechanism 11 squeezes out gas and enters it into the air storage bag 182, causing the air storage bag 182 to expand. At this time, the pressing plate 184 always presses the bearing layer 19 of the packaging bag roll against the lower end surface of the docking box 6. The cutting mechanism is provided inside the fixing plate 181 and is located on one side of the draw ring 28. After the gas in the air storage bag 182 returns to the extrusion driving mechanism 11, the pressing plate 184 is reset through the air storage bag 182. At this time, the cutting mechanism pops out to cut off the draw ring 28.

[0074] Among them, one end of the air storage bag 182 is fixedly bonded to the fixing plate 181, and the other end is fixedly bonded to the pressing plate 184. The air storage bag 182 is made of an elastic rubber material with the ability to recover deformation. After being inflated with the gas in the extrusion driving mechanism 11, the expansion of the air storage bag 182 is achieved through the extrusion driving mechanism 11. Therefore, as long as the stirring mechanism is turned on, the entire air storage bag 182 is in an inflated state. So during seed dressing, the air storage bag 182 is in an inflated state. Since the pressing mechanism 18 is linked with the extrusion driving mechanism 11, as long as the stirring mechanism stirs, the pressing action on the packaging bag can be achieved, achieving the purpose of linkage;

[0075] As Figure 12 and Figure 13As shown in the figure, the cutting mechanism includes a cutting blade 30. The cutting blade 30 is inserted into a blade installation groove provided on the fixed plate 181. A second retreating groove is provided at the position of the cutting blade 30 on the corresponding air storage bag 182. At least two expansion tubes 183 are provided in the first retreating groove. An expansion drive tube is provided at the bottom surface of the blade installation groove. Each expansion drive tube corresponds to one expansion tube 183, and the expansion tube 183 is connected and communicated with the expansion drive tube.

[0076] The expansion tube 183 includes an expansion connecting rod 1831 and a fixed sleeve 1832. One end of the expansion connecting rod 1831 is connected to the pressing plate 184, and the other end extends into the fixed sleeve 1832. An expansion sealing plug is provided at the extending end, and the expansion sealing plug seals the fixed sleeve 1832. One end of the fixed sleeve 1832 is fixedly inserted into the expansion drive tube and is connected and communicated with the expansion drive tube.

[0077] The expansion drive tube includes a drive fixed tube 32 and a drive movable rod 31. One end of the drive fixed tube 32 is fixedly installed on the bottom surface of the blade installation groove. One end of the drive movable rod 31 is inserted into the drive fixed tube 32 and a drive sealing plug is provided at the extending end. The other end of the drive movable rod 31 is connected to the cutting blade 30. An air inlet and outlet cavity 33 is formed in the drive fixed tube 32. The air inlet and outlet cavity 33 is connected and communicated with the expansion tube 183. When the expansion connecting rod 1831 is inserted into the fixed sleeve 1832, the gas in the fixed sleeve 1832 enters the air inlet and outlet cavity 33 and pushes out the drive movable rod 31, and then pushes out the cutting blade 30. Since the expansion tube 183 is connected to the pressing plate 184 and the pressing plate 184 is controlled by the air storage bag 182 to be lifted, when the air storage bag 182 lifts the pressing plate 184, the expansion connecting rod 1831 is pulled out, the drive movable rod 31 retracts, and the cutting blade 30 retracts into the blade installation groove. The state of the air storage bag 182 being inflated means that the stirring mechanism is in the working state. After the stirring mechanism stops working, the air flow in the air storage bag 182 returns to the extrusion drive mechanism 11, the air storage bag 182 resets, the pressing plate 184 resets under the action of the air storage bag 182, the pressing plate 184 no longer applies a pressing force to the packaging bag, the expansion connecting rod 1831 returns into the fixed sleeve 1832, and the expansion connecting rod 1831 will make an extrusion action relative to the expansion drive rod, so that the gas in the expansion tube 183 is extruded into the air inlet and outlet cavity 33, and then the drive movable rod 31 is pushed out. Since the cutting blade 30 is arranged on the outside of the drive movable rod 31, the cutting blade 30 is pushed out by the drive movable rod 31, and the cutting blade 30 is located on one side of the pull ring 28. After the cutting blade 30 is pushed out, it can contact the pull ring 28 to achieve the purpose of cutting. The cut packaging bag can be output to the sterile temporary storage cavity 15 through the discharge pipe 10 and stored in the sterile temporary storage cavity 15. These packaging bags can be batch processed later, and all of them can be moved into the culture room for cultivation.

[0078] When the stirring mechanism is working, the material receiving roller 20 is not working. After the stirring mechanism stops working, the material receiving roller 20 starts to work and rotates to a certain position, causing the position of the first packaging bag 22 to shift to the position of the second packaging bag 23, as Figure 9 shown. After the second packaging bag 23 is cut and the material falls, an open cavity 24 is formed, as Figure 7 shown. In this way, when the original first packaging bag 22 shifts to the position of the second packaging bag 23, the stirring mechanism can be restarted to achieve stirring and discharging, and the purpose of aseptic packaging.

[0079] A connecting spring is also fixedly arranged on the bottom surface of the blade installation groove. The other side of the connecting spring is fixedly connected to the insertion end face of the cutting blade 30. The cutting blade 30 is retracted into the blade installation groove through the connecting spring.

[0080] Among them, the stirring mechanism includes a driving motor 7, a driving motor 7 shaft, and stirring blades 13. The extrusion driving mechanism 11 is installed at the farthest end of the driving motor 7 shaft from the driving motor 7. The stirring blades 13 are installed on the driving motor 7 shaft, and the end of the driving motor 7 shaft is installed on a support bearing 113;

[0081] The extrusion driving mechanism 11 includes a cam extrusion block 111 installed on the driving motor 7 shaft. The cam extrusion block 111 is rotatably installed in a cam installation groove. An extrusion airbag 112 is arranged on the bottom surface of the cam installation groove. The extrusion airbag 112 is connected and communicated with the storage airbag 182 through a connecting pipe 4. The gas in the extrusion airbag 112 is continuously squeezed into the storage airbag 182 by the rotation of the cam extrusion block 111, causing the storage airbag 182 to expand. When the stirring mechanism works continuously, the continuous extrusion of the extrusion airbag 112 can be realized, so that the storage airbag 182 is always inflated, and the pressing plate 184 always presses the bearing layer 19 of the packaging bag, enabling the packaging bag to bear weight. In addition, the cutting mechanism is also linked with the pressing plate 184. Therefore, after the stirring mechanism stops stirring, the cutting mechanism can perform the cutting action, and at the same time, the pressing plate 184 can be released to enable the material receiving roller 20 to receive the material. Therefore, in the present invention, the stirring mechanism, the cutting mechanism, and the pressing mechanism 18 are linked together to achieve unified control, simplify the overall structure, and make the design more reasonable.

[0082] Among them, a control panel 2 is also arranged on the machine platform 3. Control buttons are arranged on the control panel 2 to achieve the purpose of controlling the whole machine.

[0083] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
