Description

Technical Field

[0001] This invention relates to the field of sealing device technology, specifically to an automatic sealing device for high-efficiency cultivation bags of antler mushrooms. Background Technology

[0002] The high-efficiency cultivation bag for deer antler mushrooms is a special container used for the artificial cultivation of deer antler mushrooms. The cultivation bag is made of polypropylene film, which has a certain strength and air permeability. The automatic sealing device for the high-efficiency cultivation bag for deer antler mushrooms refers to the equipment used to automatically seal the mouth of the cultivation bag during the cultivation process of deer antler mushrooms. Because manual sealing is inefficient, costly, and difficult to guarantee the uniformity of sealing quality, the automatic sealing device has emerged.

[0003] Existing automatic sealing devices for high-efficiency mushroom cultivation bags mostly use mechanical devices to automatically wrap plastic rope around the bag opening, and then use a rope knot forming mechanism to tie the plastic rope into a slipknot. However, when sealing cultivation bags with plastic rope, the sealing process requires wrapping and knotting the rope, which is relatively cumbersome. Moreover, only one cultivation bag can be sealed at a time, resulting in low sealing efficiency and reducing the working efficiency of the automatic sealing device for high-efficiency mushroom cultivation bags.

[0004] Therefore, we propose an automatic sealing device for high-efficiency cultivation bags of velvet mushrooms to solve the problems mentioned above. Summary of the Invention

[0012] Preferably, the lifting assembly includes a lifting frame, and cylinders are installed on the top of the pressure plate near both sides by screws. The top ends of the two cylinders are fixedly connected to the bottom of the lifting frame. A forward and reverse motor is fixedly installed on the outer surface of the lifting frame by screws, and a bidirectional threaded rod is fixedly connected to the output end of the forward and reverse motor.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When using an automatic sealing device to seal *M. deerebrionii* cultivation bags, place the bags between two elongated baffles in the conveying device. Multiple bags are simultaneously clamped by two clamping blocks, and then the bags are tightened by multiple sets of clamping blocks. By uniformly placing the circle formed by the first fastening ring and the oblique toothed ring around the sealing point of the bag, the bag is sealed without the need for multiple wrapping and knotting. This improves the working efficiency of the automatic sealing device for high-efficiency *M. deerebrionii* cultivation bags and solves the problem of low working efficiency caused by the multiple wrapping of ropes to seal bags in the existing technology.

[0017] 2. After the outer surface of the cultivation bag is sealed, the robotic arm drives two clamps to clamp one end of the oblique toothed rings fitted on multiple cultivation bags, and pulls the oblique toothed rings outward, causing the oblique toothed rings to continue moving outward of the positioning post, thus securing and sealing the fastening device fitted on the surface of the cultivation bag, preventing it from rotating to other positions when it moves to the surface of the cultivation bag.

[0018] 3. Since deer antler mushrooms need to absorb oxygen during cultivation using cultivation bags, workers can rotate the threaded bolt until the outer surface of the stop block is completely separated from the oblique toothed block on the oblique toothed ring surface. Then, the workers can move the oblique toothed ring back, increasing the inner diameter of the circle formed between the oblique toothed ring and the first fastening ring. This increases the opening at the seal of the cultivation bag until it reaches the required position. Then, the threaded bolt can be rotated again to move the stop block towards the outer surface of the oblique toothed ring, fixing the circle formed by the oblique toothed ring and the first fastening ring again. By adjusting the tightness of the seal at the cultivation bag, workers can easily adjust the sealing degree of the cultivation bag according to conditions later. Attached Figure Description

[0022] Please see Figure 1-11This invention provides a technical solution: an automatic sealing device for high-efficiency cultivation bags of *Agaricus esculentus*, comprising a pressure-resistant plate 1, a conveying device 2 disposed near the center of the top of the pressure-resistant plate 1, a pulling component 4 disposed near one edge of the top of the pressure-resistant plate 1, a lifting component 6 disposed on the top of the conveying device 2, and multiple tightening components 7 disposed inside the lifting component 6, each of the multiple tightening components 7 including a ring 701, an electric push rod 702 disposed on the inner top surface of each of the multiple rings 701, and three fixing frames 703 fixedly mounted by screws at the bottom of each of the multiple rings 701 near the outer edge, rotating parts 704 rotatably connected between the relative inner walls of the multiple fixing frames 703 by coupling components, and clamping and tightening devices for the cultivation bags fixed between the relative inner walls of the multiple rotating parts 704.

[0023] In this embodiment, when it is necessary to use an automatic sealing device to seal the *Pleurotus ostreatus* cultivation bags, the controller 3 first starts the conveying device 2, and at the same time, the *Pleurotus ostreatus* cultivation bags to be sealed are placed in a container such as... Figure 2 Between the two elongated baffles in the conveyor device 2 shown, and between the outer surfaces of the two strip bars in the conveyor belt shown, when each cultivation bag moves to the bottom of the multiple sets of clamps 403 via the conveyor device 2, the conveyor device 2 can be closed. Simultaneously, the cylinder 5 is activated, shortening it and moving the lifting frame 601 downwards to a position a certain distance from the top of the *Deer Ear Mushroom* in the cultivation bag. This, in turn, moves the multiple sets of clamps 403 downwards. Simultaneously, the forward and reverse motors 602 are activated, rotating the bidirectional threaded rod 603, which in turn moves the two clamping blocks 605 towards each other until the openings of the multiple cultivation bags are compressed and reduced, facilitating subsequent clamping and fixing of the cultivation bags. The limiting tube 604 limits the movement of the two clamping blocks 605. Additionally, as... Figure 5As shown, the clamping block 605 is composed of multiple arcs, designed to enclose the openings of multiple cultivation bags in a circular shape for easy clamping. When the multiple sets of clamps 403 move to the outer surfaces of the cultivation bags and to the upper openings, the controller 3 can activate multiple electric push rods 702 to shorten them, causing the opposing clamping blocks 705 to rotate toward the center of the multiple rings 701, thereby clamping and tightening the openings of the cultivation bags. At this time, the outer diameter of each set of clamping blocks 705 is exactly smaller than the outer diameter of the ring 701. Then, the controller 3 can activate multiple bidirectional electric telescopic rods 712 to shorten them, causing the two inclined positioning plates 714 connected to them to move toward the interior of the multiple rings 701, thereby causing the first fastening ring 707 and the helical tooth ring at the bottom of the multiple rings 701 to... The circle formed by 708 slides downward along the ring 701 under its own gravity. At the same time, as the circle formed by the first fastening ring 707 and the helical toothed ring 708 moves downward, the controller 3 activates multiple bidirectional electric telescopic rods 712 again to extend them, driving each set of inclined positioning plates 714 to move outward from the multiple rings 701 respectively, limiting the remaining circles formed by the first fastening ring 707 and the helical toothed ring 708. The circle descending under its own gravity falls along the ring 701 between the outer surfaces of the tightened cultivation bags, thus achieving a unified seal on the top of multiple cultivation bags without the need for multiple wrapping and knotting. This improves the working efficiency of the automatic sealing device for high-efficiency cultivation bags of antler mushrooms and solves the problem of low working efficiency in the existing technology of using multiple rope wrapping to seal high-efficiency cultivation bags of antler mushrooms.

[0024] like Figures 1-2 and Figures 6-11As shown, an automatic sealing device for high-efficiency cultivation bags of antler mushrooms includes a pressure-resistant plate 1. A conveying device 2 is arranged near the center of the top of the pressure-resistant plate 1. A pulling component 4 is arranged near one edge of the top of the pressure-resistant plate 1. A lifting component 6 is arranged on the top of the conveying device 2. Multiple tightening components 7 are arranged inside the lifting component 6. Each tightening component 7 includes a ring 701. An electric push rod 702 is arranged on the inner top surface of each ring 701. Three fixing frames 703 are fixedly installed at the bottom of each ring 701 near the outer edge by screws. Rotating parts 704 are rotatably connected between the relative inner walls of the multiple fixing frames 703 through coupling components. Clamping blocks 705 for clamping and tightening the cultivation bag are fixed between the relative inner walls of the multiple rotating parts 704. Multiple first fastening rings 707 are movably sleeved on the outer surface of each ring 701. One end of each first fastening ring 707 is coupled to a helical toothed ring 708, and the other end of each first fastening ring 707 is fixedly installed with a positioning post 709. A stop block 711 is slidably connected between the relative inner walls of the multiple positioning posts 709. One end of each helical toothed ring 708 passes through the multiple positioning posts 709 to surround and tighten the opening of the cultivation bag. A controller 3 is set on the outer surface of the conveying device 2. The pulling assembly 4 includes a multi-stage electric telescopic rod 401. A robotic arm 402 is set on one end of the multi-stage electric telescopic rod 401. The base of the robotic arm 402 is slidably connected to the relative inner wall of the pressure plate 1. Two clamps 403 for stretching the helical toothed ring 708 are set on the outer surface of the robotic arm 402. A vision sensor 404 for automatically detecting the position of the helical toothed ring 708 is set on the outer surface of the robotic arm 402 near the clamps 403.

[0025] In this embodiment, after the outer surface of the cultivation bag is sealed, to ensure the tightness of the seal, the controller 3 activates the multi-stage electric telescopic rod 401 to shorten it, driving the robotic arm 402 to move along the rectangular groove in the pressure-resistant plate 1 towards the nearest outer surface of the cultivation bag. Simultaneously, the vision sensor 404 is activated until it moves to the nearest outer surface of the cultivation bag. Figure 11As shown, when the vision sensor 404 detects that the robotic arm 402 has moved to a portion of the helical toothed ring 708 extending outward from the positioning post 709, the outer surface of the helical toothed ring 708 can be clamped by two clamps 403. The robotic arm 402 consists of multiple joints and connecting rods. Through different combinations and connections of these joints, the robotic arm 402 possesses different degrees of freedom, such as two, three, or even more, enabling various complex movements and postures. It can move flexibly in both horizontal and vertical directions to reach different working positions. This is a mature existing technology and will not be discussed in detail here. The light source in the vision sensor 404 emits light, illuminating the surface of the helical toothed ring 708. The camera in the vision sensor 404 focuses on the illuminated helical toothed ring according to set parameters. The ring 708 captures an image, converting its optical image into an electrical signal. This signal is then converted into digital image data via analog-to-digital conversion. The acquired raw image is preprocessed, and features are extracted from the preprocessed image based on the characteristics of the helical toothed ring 708. These extracted features are matched against a pre-stored helical toothed ring 708 model in a database to determine the position, orientation, and differences from the standard model. Based on the feature information obtained from image processing and analysis, the ring's specific position in the image is calculated, and the signal is transmitted to the robotic arm 402. The robotic arm 402 then activates two grippers 403 to clamp one end of the helical toothed ring 708 and pull it outwards, causing the ring to continue moving towards the outside of the positioning post 709. For example... Figure 11 As shown, the outer edge of the helical toothed ring 708 is provided with multiple inclined tooth blocks. When the inclined tooth blocks move to the bottom of the stop block 711, they will be squeezed by the stop block 711 and tilt inward towards the helical toothed ring 708. When the inclined tooth blocks move out of the positioning post 709, they will reset under their own elastic force, thus effectively preventing the moved helical toothed ring 708 from moving back. Through the movement of the helical toothed ring 708, the inner diameter of the circle formed by the first fastening ring 707 and the helical toothed ring 708 becomes smaller, thereby tightening the cultivation bag. After the cultivation bag is tightened, the robotic arm 402 is restarted to separate the two clamps 403. Then, the controller 3 can continue to start the multi-stage electric telescopic rod 401 to continue to shorten it, driving the clamps 403 to continue to move towards another cultivation bag, tightening and sealing the fastening device on the surface of the other cultivation bag, until all the fasteners on multiple cultivation bags are tightened, effectively preventing the cultivation bags from being loosely sealed. Figure 9 As shown, each ring 701 has a rectangular rod 706 on its surface, and each positioning post 709 has a rectangular groove on its surface that contacts the ring 701. The purpose of this is to limit the positioning post 709, and thus limit the helical tooth ring 708, preventing it from rotating to other positions when it moves to the extension of the cultivation bag surface.

[0026] like Figure 1 and Figures 6-10 As shown, an automatic sealing device for high-efficiency cultivation bags of antler mushrooms includes a pressure-resistant plate 1. A conveying device 2 is installed near the center of the top of the pressure-resistant plate 1. A pulling component 4 is installed near one edge of the top of the pressure-resistant plate 1. A lifting component 6 is installed on the top of the conveying device 2. Multiple tightening components 7 are installed inside the lifting component 6. Each tightening component 7 includes a ring 701. An electric push rod 702 is installed on the top surface of the inner surface of each ring 701. Three fixing brackets 703 are fixedly installed at the bottom of each ring 701 near the outer edge by screws. The inner walls of the multiple fixing brackets 703 are connected by... The coupling component is rotatably connected to a rotating component 704. Clamping blocks 705 for clamping and tightening the cultivation bag are fixed between the relative inner walls of the multiple rotating components 704. Multiple first fastening rings 707 are movably sleeved on the outer surfaces of multiple rings 701. One end of each of the multiple first fastening rings 707 is coupled to a helical toothed ring 708. The other end of each of the multiple first fastening rings 707 is fixedly installed with a positioning post 709. A stop block 711 is slidably connected between the relative inner walls of the multiple positioning posts 709. One end of each of the multiple helical toothed rings 708 passes through the multiple positioning posts 709 to surround and tighten the opening of the cultivation bag.

[0027] In this embodiment, since the antler mushroom needs to absorb oxygen from the air during cultivation in the cultivation bag, the seal of the cultivation bag needs to be slightly opened to allow oxygen absorption. At this time, the worker can rotate the threaded bolt 710, causing it to move outward from the positioning post 709. This, in turn, moves the stop block 711 outward from the positioning post 709 until its outer surface is completely separated from the oblique toothed block on the surface of the oblique toothed ring 708. The worker can then move the oblique toothed ring 708 back, increasing the inner diameter of the circle formed by the oblique toothed ring 708 and the first fastening ring 707, thereby increasing the opening at the seal of the cultivation bag. Continue rotating the threaded bolt 710 until it reaches the required position, then rotate it again to move the stop block 711 towards the outer surface of the helical toothed ring 708, thus fixing the circle formed by the helical toothed ring 708 and the first fastening ring 707. By adjusting the tightness of the sealing at the cultivation bag, it is convenient for staff to adjust the sealing degree of the cultivation bag according to the conditions later. The helical toothed ring 708 and the first fastening ring 707 are both made of silicone rubber, which has high chemical stability, good tolerance to various chemicals, and is non-toxic and odorless. Silicone rubber has excellent elastic recovery, and even after multiple stretching and compression, it can quickly return to its original shape, ensuring the reliability of the plastic bag seal.

[0028] The usage and working principle of this device are as follows: When it is necessary to use the automatic sealing device to seal the *Pleurotus ostreatus* cultivation bags, first start the conveyor device 2, and at the same time place the *Pleurotus ostreatus* cultivation bags to be sealed in the container. Figure 2 Between the two elongated baffles in the conveyor device 2 shown, and between the outer surfaces of the two strip bars in the conveyor belt shown, when each cultivation bag moves to the bottom of the multiple sets of clamps 403 via the conveyor device 2, the conveyor device 2 can be closed. At the same time, the cylinder 5 is activated, shortening it and moving the lifting frame 601 downwards to a position a certain distance from the top of the mushroom in the cultivation bag. This, in turn, moves the multiple sets of clamps 403 downwards. Simultaneously, the forward and reverse motors 602 are activated, causing the bidirectional threaded rod 603 to rotate, which in turn moves the two clamping blocks 605 towards each other until... The openings of multiple cultivation bags are compressed and reduced to facilitate clamping and fixing them later. When multiple sets of clamps 403 move between the outer surfaces of multiple cultivation bags and to the upper openings, the controller 3 can activate multiple electric actuators 702 to shorten them, causing the corresponding clamping blocks 705 to rotate towards the center of multiple rings 701, thereby clamping and tightening the openings of multiple cultivation bags. At this time, the outer diameter of each set of clamping blocks 705 is exactly smaller than the outer diameter of the rings 701. Then, the controller 3 can activate multiple bidirectional electric telescopic rods. 712, shortening it, respectively drives the two inclined positioning plates 714 connected to it to move inwards into the plurality of rings 701, so that the circle formed by the first fastening ring 707 and the helical tooth ring 708 at the bottom of the plurality of rings 701 slides downwards along the ring 701 under its own gravity. During the downward movement of the circle formed by the first fastening ring 707 and the helical tooth ring 708, the controller 3 again activates the plurality of bidirectional electric telescopic rods 712, extending them, driving each set of inclined positioning plates 714 to move outwards from the plurality of rings 701, and so on for the remaining ones. The circle formed by the first fastening ring 707 and the helical toothed ring 708 provides a limiting position. Under its own gravity, the descending circle falls along the ring 701 onto the outer surface of the tightened cultivation bag, thus achieving a uniform seal on the tops of multiple cultivation bags without the need for multiple wrapping and knotting. After the outer surface of the cultivation bag is sealed, to ensure the tightness of the seal, the controller 3 activates the multi-stage electric telescopic rod 401, shortening it and driving the robotic arm 402 to move along the rectangular groove in the pressure-resistant plate 1 towards the nearest outer surface of the cultivation bag. Simultaneously, the vision sensor 404 is activated until it moves to the nearest outer surface of the cultivation bag. Figure 11As shown, when the vision sensor 404 detects that the robotic arm 402 has moved to a portion of the helical toothed ring 708 extending outward from the positioning post 709, the outer surface of the helical toothed ring 708 can be clamped by the two clamps 403. Based on the feature information of the helical toothed ring 708 obtained through image processing and analysis, the vision sensor 404 calculates its specific position in the image and transmits the signal to the robotic arm 402. The robotic arm 402 then activates the two clamps 403 to clamp one end of the helical toothed ring 708 and pulls the helical toothed ring 708 outward, causing it to continue moving outward from the positioning post 709. Multiple inclined tooth blocks are provided on the outer edge of the helical toothed ring 708. When the inclined tooth blocks move to the stop 711... When the bottom is reached, it will be squeezed by the stop block 711 and tilted inward towards the helical toothed ring 708. When the tilted toothed ring moves out of the positioning post 709, it will reset under its own elastic force, thus effectively preventing the displaced part of the helical toothed ring 708 from moving back. Through the movement of the helical toothed ring 708, the inner diameter of the circle formed by the first fastening ring 707 and the helical toothed ring 708 becomes smaller, thereby tightening the cultivation bag. After the cultivation bag is tightened, the robotic arm 402 is restarted to separate the two clamps 403. Then, the controller 3 can continue to start the multi-stage electric telescopic rod 401 to continue to shorten it, driving the clamps 403 to continue to move towards the other cultivation bag, and then move the other... The fastening device fitted onto the surface of each cultivation bag is used to secure and seal the bag until all fasteners on multiple cultivation bags are tightened. Each ring 701 has a rectangular rod 706 on its surface, and each positioning post 709 has a rectangular groove on the surface that contacts the ring 701. Since the antler mushroom needs to absorb oxygen from the air during cultivation in the cultivation bags, the seal of the cultivation bag needs to be slightly opened to allow oxygen absorption. At this time, the operator can rotate the threaded bolt 710 to move the threaded bolt 710 outward from the positioning post 709, thereby moving the stop block 711 outward from the positioning post 709 until its outer surface is completely in contact with the helical tooth ring. When the helical toothed block on the surface of 708 separates, the operator can move the helical toothed ring 708 back, increasing the inner diameter of the circle formed between the helical toothed ring 708 and the first fastening ring 707, thereby increasing the opening at the seal of the cultivation bag until it is enlarged to the required position. Then, the threaded bolt 710 can be rotated again, causing the stop block 711 to move towards the outer surface of the helical toothed ring 708, fixing the circle formed by the helical toothed ring 708 and the first fastening ring 707 again. By adjusting the tightness of the seal at the cultivation bag, the controller 3 is electrically connected to the conveying device 2, the multi-stage electric telescopic rod 401, the vision sensor 404, the forward and reverse motor 602, the servo motor 608, and the electric push rod 702.

[0029] The wiring diagrams of the conveying device 2, controller 3, multi-stage electric telescopic rod 401, vision sensor 404, forward and reverse motor 602, servo motor 608, and electric push rod 702 in this invention are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the conveying device 2, controller 3, multi-stage electric telescopic rod 401, vision sensor 404, forward and reverse motor 602, servo motor 608, and electric push rod 702 will not be explained in detail.
