Description

Technical Field

[0001] The present invention relates to the technical field of King Oyster Mushroom bag packaging, in particular to a packaging device for King Oyster Mushroom bag production. Background Art

[0002] King oyster mushroom bags are the carriers used to cultivate King oyster mushrooms. They contain all the nutrients required for the growth of King oyster mushrooms. The bags are usually made of a variety of raw materials in a certain proportion. These raw materials include sawdust, bran, corn cobs, soybean meal, lime, etc. The raw materials are mixed into culture medium and packaged to form bags.

[0003] When preparing the culture medium, if the raw materials are not fully mixed and the moisture is not properly controlled, the culture medium will easily clump, and the prepared culture medium will also easily clump if stored in a humid environment. The culture medium inside the bag should maintain good air permeability to facilitate the breathing of mycelium. Agglomerated culture medium may cause local air permeability to deteriorate, affecting the normal growth and spread of mycelium. When packaging the culture medium, the culture medium is generally directly placed in the packaging bag for packaging. Agglomerated culture medium will also be mixed into the packaging bag, thereby affecting the initial colonization and subsequent spread of mycelium. In addition, poor air permeability in local areas will limit the oxygen supply, inhibit mycelium respiration, and reduce the activity of mycelium. Summary of the Invention

Six bidirectional screw motors 15 are installed on the top of the rotating plate 13 at evenly spaced intervals by bolts. The bidirectional screw of the bidirectional screw motor 15 is threadedly connected to the slide rail 14. Two slide plates 16 are slidably connected to the slide rail 14. The bidirectional screw of the screw motor 15 and the slide 16 are connected by threads. The threads on the two slides 16 on the same slide rail 14 are in opposite directions, so that the bidirectional screw motor 15 can drive the two slides 16 to move in opposite directions.

The guide sleeve 26 is slidably connected with a sliding plate 27. The roller shaft 25 is in contact with the top of the sliding plate 27, and the screen 9 is tilted, so the roller shaft 2 5 moves up and down obliquely. When the sliding plate 27 pushes the roller 25 to move upward, the roller 25 rolls on the top of the sliding plate 27, which can reduce the friction force of the sliding plate 27 pushing the connecting frame 24, thereby avoiding wear of the sliding plate 27 and the connecting frame 24. The bottom of the sliding plate 27 is rotatably connected to a roller 28. A push plate 29 is connected to the middle of the top of the rotating disk 13 by bolts. The roller 28 is in contact with the top of the push plate 29. When the push plate 29 rotates, the roller 28 rolls on the push plate 29, thereby avoiding friction between the push plate 29 and the bottom of the sliding plate 27. A push portion 291 is provided on the top of the push plate 29.

[0035] Reference Figure 10The shaking mechanism includes a mounting frame 30, a servo motor 31, a rotating shaft 32, a disc 33 and a connecting rod 34. The upper front part of the gathering frame 3 is connected to the mounting frame 30 by bolts, the servo motor 31 is installed on the left side of the top of the mounting frame 30 by bolts, and the rotating shaft 32 is rotatably connected to the top right side of the mounting frame 30.

[0036] Referring to the figure, the metering mechanism includes a metering wheel 35 and a second stepper motor 36. The metering wheel 35 is rotatably connected in the circular frame 4. There are four feeding spaces on the metering wheel 35. The four feeding spaces are evenly spaced and have the same capacity. The second stepper motor 36 is installed on the front side of the circular frame 4 by bolts, and the output shaft of the second stepper motor 36 is connected to the front end of the metering wheel 35.

[0037] Reference Figure 1 , also includes a bracket 37 and a feeding conveyor 38. The bracket 37 is connected to the left side of the top of the base plate 1 by bolts, and the feeding conveyor 38 is installed on the upper part of the bracket 37 by bolts. The feeding conveyor 38 is located above the screen 9.

[0038] The packaging bag is sent between the two electric suction cups 17 through the bag feeding equipment, and then the bidirectional screw motor 15 is controlled to drive the two slides 16 to move in the direction of approaching each other, thereby driving the two electric suction cups 17 to move in the direction of approaching each other, so that the electric suction cups 17 and the packaging bag are in contact, and the electric suction cups 17 suck the packaging bag, and then the bidirectional screw motor 15 is controlled to drive the two slides 16 to move in the direction of moving away from each other, thereby driving the two electric suction cups 17 to move in the direction of moving away from each other, and the electric suction cups 17 open the bag mouth of the packaging bag, and then the output shaft of the first stepper motor 12 is controlled to drive the rotating disk 13 to rotate, and the rotating disk 13 drives the packaging bag to rotate, and the packaging bag is rotated to the bottom of the discharge frame 5, and then the movable end of the hydraulic cylinder 10 is controlled to extend to drive The mounting plate 11 moves upward, and the mounting plate 11 drives the packaging bag to move upward, and the bag mouth of the packaging bag is put on the bottom of the discharge frame 5, and then the crushed and mixed culture material is sent to the feeding conveyor 38, and the feeding conveyor 38 transports the culture material to the right, and transports the culture material to the screen 9. The culture material is evenly distributed on the feeding conveyor 38, so that the culture material can be evenly transported, and the screen 9 is prevented from being blocked due to excessive transportation of the culture material. The screen 9 can screen the agglomerated culture material, and the unclumped culture material will fall into the aggregation frame 3, and the agglomerated culture material will be prevented from falling into the packaging bag, ensuring the air permeability of the culture material, thereby ensuring the initial colonization and subsequent spread of the mycelium. The culture material falls into the feeding space of the control wheel 35 along the aggregation frame 3, and the second step is The output shaft of the motor 36 drives the metering wheel 35 to rotate. Each time the output shaft of the second stepper motor 36 rotates 90 degrees, the metering wheel 35 also rotates 90 degrees each time. The culture medium in the feeding space of the metering wheel 35 will fall into the packaging bag for packaging to form a fungus bag. After the packaging is completed, the movable end of the hydraulic cylinder 10 is shortened to drive the mounting plate 11 to move downward. The mounting plate 11 drives the packaging bag to move downward so that the bag opening of the packaging bag is separated from the bottom of the discharge frame 5. The above operation is repeated to continue packaging the culture medium. The capacity of the four feeding spaces on the metering wheel 35 is consistent, which can ensure that the amount of culture medium packaged each time is consistent, avoiding uneven growth of mycelium caused by inconsistent amount of culture medium, and starting the servo motor 31. The output of the servo motor 31 The shaft drives the rotating shaft 32 to rotate through the sprocket chain, thereby driving the disc 33 to rotate. The disc 33 drives the sliding frame 8 and the screen 9 to move back and forth through the connecting rod 34, so that the culture material on the screen 9 is active, so that the unagglomerated culture material can better fall into the aggregation frame 3. When the rotating disk 13 rotates, it will drive the pushing disk 29 to rotate, and the pushing part 291 of the pushing disk 29 will push the roller 28 to move upward, and the roller 28 drives the sliding plate 27 to move upward, and the sliding plate 27 drives the roller shaft 25 to move upward, and the roller shaft 25 drives the connecting frame 24 to move upward, and the connecting frame 24 drives the pressing plate 20 to move upward, and the spring 21 is compressed, and the agglomerated culture material on the screen 9 will roll to the bottom of the pressing plate 20, and the gathering plate 23 can gather the agglomerated culture material.This allows the agglomerated culture material to roll better under the pressing plate 20. When the pushing portion 291 of the pushing plate 29 and the roller 28 are out of contact, the pressing plate 20 moves downward under the action of the spring 21. At this time, the screen 9 is moving back and forth. The pressing plate 20 and the screen 9 work together to rub the agglomerated culture material, allowing the pressing plate 20 to crush the agglomerated culture material. The crushed culture material passes through the screen 9 and falls into the gathering frame 3, preventing the agglomerated culture material from accumulating on the screen 9. The heater 22 can heat the crushed culture material, reduce the moisture on the crushed culture material, and prevent the crushed culture material from agglomerating again.

[0039] Reference Figure 1 and Figure 12 , also includes support columns 39, a discharge conveyor 40 and a baffle 41.

The tops of the four connecting blocks 42 are commonly connected to a support ring 43. The support ring 43 is located below the rotating disk 13, and a notch is provided on the rear side of the support ring 43.

[0041] After the culture medium is packaged, the movable end of the hydraulic cylinder 10 is controlled to shorten, driving the mounting plate 11 to move downward, and the mounting plate 11 drives the packaging bag to move downward, so that the bag opening of the packaging bag is separated from the bottom of the discharge frame 5, and the packaged culture medium falls onto the support ring 43. The support ring 43 can support the packaged culture medium to prevent the packaged culture medium from falling off the electric suction cup 17. The output shaft of the first stepper motor 12 drives the rotating disk 13 to rotate, and the rotating disk 13 drives the packaged culture medium to rotate. When the packaged culture medium corresponds to the notch on the support ring 43, the electric suction cup 17 is controlled to loosen the packaged culture medium, and the packaged culture medium falls onto the discharge conveyor 40 through the notch on the support ring 43. The discharge conveyor 40 transports the packaged culture medium backward and transports the packaged culture medium to the next workstation for automatic unloading.
