[0023] In this embodiment, when the automatic sealing device is needed to seal the Pleurotus eryngii cultivation bag, the conveying device 2 is first started by the controller 3, and the Pleurotus eryngii cultivation bag to be sealed is placed on the Figure 2 The conveying device 2 shown in the figure is between the two long baffles, and each cultivation bag is respectively between the outer surfaces of the two strip rods in the conveyor belt in the figure. When each cultivation bag is moved to the bottom of the multiple groups of clamps 403 through the conveying device 2, the conveying device 2 can be closed, and the cylinder 5 is started at the same time to shorten it, driving the lifting frame 601 to move downward to a position a certain distance from the top of the deer ear mushroom in the cultivation bag, thereby driving the multiple groups of clamps 403 to move downward, and at the same time starting the forward and reverse motor 602 to drive the bidirectional threaded rod 603 to rotate, thereby driving the two clamping blocks 605 to move toward each other until the empty openings of the multiple cultivation bags are squeezed and shrunk, so as to facilitate the clamping and fixing of the cultivation bags in the later stage. Among them, the limiting tube 604 plays a limiting role on the two clamping blocks 605. In addition, as Figure 5As shown, the clamping block 605 is composed of multiple arcs, and its purpose is to surround the empty openings of the multiple cultivation bags into a circle to facilitate later clamping. When the multiple groups of clamps 403 are respectively moved between the outer surfaces of the multiple cultivation bags and at the upper empty openings, the multiple electric push rods 702 can be started by the controller 3 to shorten them, driving the clamping blocks 705 opposite to them to rotate toward the centers of the multiple circular rings 701, thereby clamping and tightening the bag openings of the multiple cultivation bags respectively. At this time, the outer diameter of each group of clamping blocks 705 is just smaller than the outer diameter of the circular ring 701, and then the multiple two-way electric telescopic rods 712 can be started by the controller 3 to shorten them, and drive the two inclined positioning plates 714 connected thereto to move toward the inside of the multiple circular rings 701 respectively, so that the first fastening ring 707 and the bevel gear ring located at the bottom of the multiple circular rings 701 The circle formed by the first fastening ring 707 and the bevel gear ring 708 slides downward along the circular ring 701 under the action of its own gravity.

The descending circle under the action of its own gravity falls along the circular ring 701 to the outer surface of the tightened cultivation bag, that is, the unified sealing of the tops of the multiple cultivation bags is realized without the need for multiple windings and knotting, thereby improving the working efficiency of the automatic sealing device for the efficient cultivation bag of velvet antler mushroom, and solving the problem of low working efficiency in the prior art of using multiple rope windings to seal the bag in the process of sealing the efficient cultivation bag of velvet antler mushroom.

[0024] like Figure 1-Figure 2 and Figure 6-Figure 11As shown, an automatic sealing device for a high-efficiency cultivation bag of velvet antler mushroom comprises 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 side edge of the top of the pressure-resistant plate 1, a lifting component 6 is arranged on the top of the conveying device 2, a plurality of tightening components 7 are arranged inside the lifting component 6, the plurality of tightening components 7 all comprise a circular ring 701, an electric push rod 702 is arranged on the inner top surface of the plurality of circular rings 701, three fixing frames 703 are fixedly installed near the outer edge at the bottom of the plurality of circular rings 701 by screws, rotating members 704 are rotatably connected between the relative inner walls of the plurality of fixing frames 703 by coupling components, clamping blocks 705 for clamping and tightening the cultivation bag are fixed between the relative inner walls of the plurality of rotating members 704, a plurality of first fastening rings 707 are movably sleeved on the outer surfaces of the plurality of circular rings 701, and a plurality of first fastening rings 707 are movably sleeved on the outer surfaces of the plurality of circular rings 701. One end of each first fastening ring 707 is coupled with a bevel gear ring 708, and the other ends of the multiple first fastening rings 707 are fixedly installed with positioning columns 709. Blocks 711 are slidably connected between the relative inner walls of the multiple positioning columns 709. One ends of the multiple bevel gear rings 708 pass through the multiple positioning columns 709 to surround and tighten the bag openings of the cultivation bags. A controller 3 is arranged on the outer surface of the conveying device 2. The pulling component 4 includes a multi-stage electric telescopic rod 401. A mechanical arm 402 is arranged at one end of the multi-stage electric telescopic rod 401. The base portion of the mechanical arm 402 is slidably connected to the relative inner wall of the pressure-resistant plate 1. Two clamps 403 for stretching the bevel gear ring 708 are arranged on the outer surface of the mechanical arm 402. A visual sensor 404 for automatically detecting the position of the bevel gear ring 708 is arranged at a position on the outer surface of the mechanical arm 402 near the clamp 403.

[0025] In this embodiment, after the outer surface of the cultivation bag is sealed, in order to ensure the rigor of the sealing, the multi-stage electric telescopic rod 401 is activated by the controller 3 to shorten it, driving the mechanical arm 402 to move along the rectangular groove in the pressure-resistant plate 1 to the outer surface of the cultivation bag closest to it, and at the same time activating the visual sensor 404 until it moves to the outer surface of the cultivation bag that is closest to it. Fig.11In the position shown, when the visual sensor 404 detects that the robot arm 402 moves to the outside of the positioning column 709 and extends outwardly to the part of the bevel gear ring 708, the outer surface of the bevel gear ring 708 can be clamped by two clamps 403, wherein the robot arm 402 is composed of multiple joints and connecting rods. Through the combination and connection of different joints, the robot arm 402 has different degrees of freedom of movement, such as two degrees of freedom, three degrees of freedom or even more degrees of freedom, so as to realize various complex movements and postures, and can be flexibly moved in the horizontal and vertical directions to reach different working positions. It is an existing mature technology and will not be introduced in detail here. The light source in the visual sensor 404 will emit light to illuminate the surface of the bevel gear ring 708, and the camera in the visual sensor 404 will focus on the illuminated bevel gear according to the set parameters. The ring 708 is photographed, and its optical image is converted into an electrical signal. After analog-to-digital conversion, the electrical signal is converted into digital image data. The collected original image is pre-processed. According to the characteristics of the bevel gear ring 708, its features are extracted from the pre-processed image. The extracted features are matched with the bevel gear ring 708 model pre-stored in the database to determine the position, posture and difference information of the bevel gear ring 708 with the standard model in the image. According to the feature information of the bevel gear ring 708 obtained by image processing and analysis, its specific position in the image is calculated, and the signal is transmitted to the robot arm 402. The two clamps 403 are activated by the robot arm 402 to clamp one end of the bevel gear ring 708 and stretch the bevel gear ring 708 outward, so as to drive the bevel gear ring 708 to continue to move to the outside of the positioning column 709. Fig.11 As shown, a plurality of inclined tooth blocks are arranged on the outer edge of the helical tooth ring 708. When the inclined tooth block moves to the bottom of the stop block 711, it will be squeezed by the stop block 711 and tilted toward the inside of the helical tooth ring 708. When the inclined tooth block moves out of the interior of the positioning column 709, it will be reset under the action of its own elastic force, thereby effectively preventing the moved out helical tooth ring 708 from moving back. Through the movement of the helical tooth ring 708, the inner diameter of the circle formed by the first fastening ring 707 and the helical tooth ring 708 becomes smaller, thereby tightening the cultivation bag. When the cultivation bag is tightened, the mechanical arm 402 is started again to separate the two clamps 403. The multi-stage electric telescopic rod 401 can be continuously started by the controller 3 to make it continue to shorten, driving the clamp 403 to continue to move toward the direction of another cultivation bag, and tightening and sealing the fastening device set on the surface of the other cultivation bag until the fasteners on the multiple cultivation bags are tightened, effectively preventing the occurrence of loose sealing of the cultivation bag. Fig. 9 As shown, a rectangular rod 706 is provided on the surface of each circular ring 701, and a rectangular groove is provided on the surface of each positioning column 709 that contacts the circular ring 701, the purpose of which is to limit the positioning column 709, and then limit the helical gear ring 708, to prevent it from rotating to other positions when it moves to the extension of the surface of the cultivation bag.

[0026] like Figure 1 and Figure 6-Figure 10 As shown, an automatic sealing device for an efficient cultivation bag of velvet antler mushroom comprises 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 the edge of one side of the top of the pressure-resistant plate 1, a lifting component 6 is arranged on the top of the conveying device 2, a plurality of tightening components 7 are arranged inside the lifting component 6, the plurality of tightening components 7 all comprise a circular ring 701, an electric push rod 702 is arranged on the inner top surface of the plurality of circular rings 701, three fixing frames 703 are fixedly installed near the outer edge of the bottom of the plurality of circular rings 701 by screws, and the relative inner walls of the plurality of fixing frames 703 are connected by The coupling component is rotatably connected with a rotating member 704, and clamping blocks 705 for clamping and tightening the cultivation bag are fixed between the relative inner walls of the multiple rotating members 704. The outer surfaces of the multiple circular rings 701 are movably sleeved with multiple first fastening rings 707, and one ends of the multiple first fastening rings 707 are coupled with a helical gear ring 708, and the other ends of the multiple first fastening rings 707 are fixedly installed with positioning columns 709. Blocks 711 are slidably connected between the relative inner walls of the multiple positioning columns 709, and one ends of the multiple helical gear rings 708 respectively pass through the multiple positioning columns 709 to surround and tighten the bag openings of the cultivation bags.

[0027] In this embodiment, since the velvet antler mushroom needs to absorb oxygen from the air during the cultivation process using the cultivation bag, the seal of the cultivation bag needs to be opened a little during the cultivation process in the cultivation bag to absorb oxygen. At this time, the staff can rotate the threaded bolt 710 to move the threaded bolt 710 toward the outside of the positioning column 709, thereby driving the stopper 711 to move toward the outside of the positioning column 709 until its outer surface is completely separated from the beveled tooth block on the surface of the beveled tooth ring 708. The staff can move the beveled tooth ring 708 back to increase the inner diameter of the circle formed by the beveled tooth ring 708 and the first fastening ring 707, thereby increasing the opening at the seal of the cultivation bag. Until it increases to the required position, the threaded bolt 710 can be rotated again to drive the stopper 711 to move toward the outer surface of the helical toothed ring 708, and the circle formed by the helical toothed ring 708 and the first fastening ring 707 can be fixed again. By adjusting the tightness of the sealing of the cultivation bag, it is convenient for the staff to adjust the sealing degree of the cultivation bag according to the conditions in the later stage. Among them, 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 chemical substances, and is non-toxic and odorless. The elastic recovery of silicone rubber is excellent. Even after multiple stretching and compression, it can quickly return to its original shape to ensure the reliability of the plastic bag sealing.

[0028] The use method and working principle of the device: When the automatic sealing device is needed to seal the Pleurotus eryngii cultivation bag, first start the conveying device 2, and at the same time place the Pleurotus eryngii cultivation bag to be sealed on the surface of the bag. Figure 2 The conveying device 2 shown in the figure is between the two long baffles, and each cultivation bag is respectively between the outer surfaces of the two strip rods in the conveyor belt in the figure. When each cultivation bag is moved to the bottom of the multiple sets of clamps 403 through the conveying device 2, the conveying device 2 can be closed, and the cylinder 5 is started at the same time to shorten it, driving the lifting frame 601 to move downward to a position a certain distance from the top of the deer ear mushroom in the cultivation bag, thereby driving the multiple sets of clamps 403 to move downward, and at the same time starting the forward and reverse motor 602 to drive the bidirectional threaded rod 603 to rotate, thereby driving the two clamps 605 to move toward each other until The openings of the multiple cultivation bags are squeezed and shrunk to facilitate the clamping and fixing of the cultivation bags in the later stage. When the multiple groups of clamps 403 are respectively moved to the outer surfaces of the multiple cultivation bags and at the upper openings, the multiple electric push rods 702 can be started by the controller 3 to shorten them, driving the clamping blocks 705 opposite thereto to rotate toward the centers of the multiple rings 701, thereby clamping and tightening the bag openings of the multiple cultivation bags. At this time, the outer diameter of each group of clamping blocks 705 is just smaller than the outer diameter of the ring 701, and then the multiple bidirectional electric telescopic rods can be started by the controller 3. 712, shortening it, driving the two inclined positioning plates 714 connected thereto to move respectively toward the inside of the plurality of circular rings 701, so that the circle formed by the first fastening ring 707 and the oblique gear ring 708 at the bottom of the plurality of circular rings 701 slides downward along the circular rings 701 under the action of its own gravity. During the downward movement of the circle formed by the first fastening ring 707 and the oblique gear ring 708, the plurality of bidirectional electric telescopic rods 712 are activated again by the controller 3 to extend it, driving each group of inclined positioning plates 714 to move respectively toward the outside of the plurality of circular rings 701, and the remaining The circle formed by the first fastening ring 707 and the bevel gear ring 708 is limited, and the circle descending under the action of its own gravity falls along the ring 701 to the outer surface of the tightened cultivation bag, thereby realizing the unified sealing of the tops of multiple cultivation bags without the need for multiple windings and knotting. When the outer surface of the cultivation bag is sealed, in order to ensure the rigor of the sealing, the multi-stage electric telescopic rod 401 is started by the controller 3 to shorten it, driving the mechanical arm 402 to move along the rectangular groove in the pressure-resistant plate 1 to the outer surface of the cultivation bag closest to it, and at the same time starting the visual sensor 404 until it moves to the outer surface of the cultivation bag that is closest to it. Fig.11When the vision sensor 404 detects that the robot arm 402 moves to the part of the bevel gear ring 708 extending outward outside the positioning column 709, the outer surface of the bevel gear ring 708 can be clamped by the two clamps 403. The vision sensor 404 calculates its specific position in the image based on the feature information of the bevel gear ring 708 obtained by image processing and analysis, and transmits the signal to the robot arm 402. The robot arm 402 starts the two clamps 403 to clamp one end of the bevel gear ring 708 and stretch the bevel gear ring 708 outward, driving the bevel gear ring 708 to continue to move to the outside of the positioning column 709. A plurality of inclined tooth blocks are set on the outer edge of the bevel gear ring 708. When the inclined tooth block moves to the stop block 711 When the inclined tooth block moves out of the positioning column 709, it will be reset under the action of its own elastic force, thereby effectively preventing the moved out part of the inclined tooth ring 708 from moving back. The movement of the inclined tooth ring 708 makes the inner diameter of the circle formed by the first fastening ring 707 and the inclined tooth ring 708 smaller, thereby tightening the cultivation bag. When the cultivation bag is tightened, the mechanical arm 402 is started again to separate the two clamps 403, and the multi-stage electric telescopic rod 401 can be continuously started through the controller 3 to make it continue to shorten, driving the clamp 403 to continue to move in the direction of the other cultivation bag, tightening the other The fastening devices set on the surfaces of the cultivation bags are used to fasten and package until the fasteners on the multiple cultivation bags are fastened. A rectangular rod 706 is set on the surface of each ring 701, and a rectangular groove is opened on the surface of each positioning column 709 that contacts the ring 701. Since the velvet mushroom needs to absorb oxygen in the air during the cultivation of the cultivation bag, the seal of the cultivation bag needs to be opened a little during the cultivation of the velvet mushroom in the cultivation bag to absorb oxygen. At this time, the staff can rotate the threaded bolt 710 to move the threaded bolt 710 toward the outside of the positioning column 709, thereby driving the stopper 711 to move toward the outside of the positioning column 709 until its outer surface is completely aligned with the bevel gear ring. The bevel gear block on the surface of 708 is separated, and the staff can move the bevel gear ring 708 back to increase the inner diameter of the circle formed by the bevel gear ring 708 and the first fastening ring 707, thereby increasing the opening of the sealing portion of the cultivation bag until it increases to the required position, and then the threaded bolt 710 can be rotated again to drive the stopper 711 to move toward the outer surface of the bevel gear ring 708, and fix the circle formed by the bevel gear ring 708 and the first fastening ring 707 again, and adjust the tightness of the sealing portion of the cultivation bag, wherein the controller 3 is electrically connected to the conveying device 2, the multi-stage electric telescopic rod 401, the visual sensor 404, the forward and reverse motor 602, the servo motor 608 and the electric push rod 702.
