[0033] like Figures 1 to 7 As shown, an automatic mushroom stick bag removal device includes a frame 300, on which a pushing device 200, a roller line 400, a material blocking mechanism 700, a mushroom bag cutting device 500 and a bag tearing mechanism 600 are sequentially installed;

[0034] The roller line 400 includes a plurality of rollers mounted on a frame 300, with a circle of grooves provided in the middle of the rollers; the grooves are conducive to keeping the mushroom sticks in the center position of the device.

[0035] The mushroom bag cutting device 500 includes a door frame 501 fixedly connected to the frame 300, a lifting mechanism is installed on the door frame 501, a cutting motor 506 is installed on the lifting end of the lifting mechanism, and a cutting disc 505 is installed on the output shaft of the cutting motor 506; the lifting mechanism drives the rotary cutting disc 505 to move up and down to cut the end of the mushroom bag, and the mushroom sticks are loaded into the mushroom bag from the bag opening. The bag opening is tied and sealed with a nylon tie. The mushroom bag end is the part where the tie and the bag opening are tied with the tie. When the cutting device cuts off the mushroom bag end, the bag opening is completely opened.

[0036] The bag-tearing mechanism 600 comprises two mechanisms, one on each side of the lifting mechanism. Each mechanism 600 comprises a support shaft 601 fixedly connected to the frame 300. The support shaft 601 is coated with a torsion spring 602 and a sleeve 604. A hook 603 is fixedly connected to the sleeve 604. The two torsion springs 602 drive the two hooks 603 to bend one end together. The torsion springs 602 generate a torsional force that helps tighten the bag. Furthermore, a cover is coated on the sleeve 604, with a notch for the hooks 603 to rotate. This cover prevents powder from the mushroom stick from falling into the gap between the sleeve 604 and the torsion spring 602, which could affect the rotation of the hook 603.

[0037] Preferably, a material blocking mechanism 700 is provided between the drum line 400 and the mushroom bag cutting device 500. There are two material blocking mechanisms 700, which are arranged on both sides of the drum line 400. The material blocking mechanism 700 includes a first bracket 702. A torsion motor 701 and a rotating shaft 703 are respectively installed at the upper and lower ends of the first bracket 702. The output shaft of the torsion motor 701 is connected to the rotating shaft 703. A blocking plate 704 is connected to the rotating shaft 703. There is a gap between the two blocking plates 704 in the two material blocking mechanisms 700, and the pushing device 200 pushes the end of the mushroom stick to emerge from the gap. The torsion motor 701 is a servo worm gear reduction motor, which can self-lock the blocking plate 704. When the mushroom sticks falling on the roller line 400 are pushed and fed by the pushing device 200, the end faces of the mushroom sticks are pressed against the two blocking plates 704, and the ends of the mushroom sticks are exposed from the gap. In this way, the mushroom sticks are fixed and only the ends are exposed, avoiding the shaking of the mushroom bags when the cutting device cuts.

[0038] Preferably, a belt conveyor 100 is provided on one side of the drum line 400. A plurality of guide rod inclined plates 102 are connected to the frame 300 between the belt conveyor 100 and the drum line 400.

The baffle plate 900 is located above the drum line 400 and is equipped with a travel switch 901. The belt conveyor 100 is used for automatic loading of mushroom sticks. After unbagging one mushroom stick, the belt conveyor 100 conveys the next mushroom stick to the guide rod inclined plates 102. The mushroom stick is guided by the guide rod inclined plates 102 to the drum line 400, thereby achieving automatic and continuous loading of mushroom sticks.

[0039] Preferably, a plurality of ridges 101 are provided on the belt surface of the belt conveyor 100, and the mushroom sticks are placed between two ridges 101. The ridges 101 are used to separate the mushroom sticks on the belt conveyor 100 so that they can be continuously unpacked according to the beat set by the controller.

[0040] Preferably, an air distribution block 508 is installed on the door frame 501, and a cavity is provided in the air distribution block 508. The air distribution block 508 is connected to a plurality of air jet nozzles 507 in communication with the cavity. The air distribution block 508 is connected to an air intake pipe, and an electromagnetic valve is installed on the air intake pipe (the air intake pipe and the electromagnetic valve are not drawn in the figure). The air intake pipe is connected to a compressed air source, and the compressed air enters the cavity through the air intake pipe and is then ejected from each spray nozzle to blow the fungus bags on the hook 603 in and out.

[0041] Preferably, a photoelectric switch 705 is mounted on the first bracket 702. The photoelectric switch 705 and the travel switch 901 are connected to the controller input terminal, and the torsion motor 701, the solenoid valve, the belt conveyor 100, the lifting mechanism, and the pushing device 200 are connected to the controller output terminal. The controller is a PLC controller to achieve automatic bagging of the mushroom sticks.

[0042] Preferably, the pushing device 200 includes an electric push rod or a cylinder installed on the frame 300.

[0043] Preferably, a mushroom stick collection frame 103 is provided on one side of the bag tearing mechanism 600, a material guide rail is provided between the mushroom stick collection frame 103 and the bag tearing mechanism 600, and a mushroom bag collection frame 104 is provided below the bag tearing mechanism 600. The mushroom stick collection frame 103 and the mushroom bag collection frame 104 are used to collect mushroom sticks and mushroom bags respectively, which is convenient for staff to organize.

[0044] Preferably, the lifting device includes a lifting motor 502 and a shaft sleeve 604 mounted on the gantry 501. The shaft sleeve 604 is provided with a lifting shaft 504. The upper end of the lifting shaft 504 is connected to the lifting motor 502 through a crank-connecting rod mechanism 503. The cutting motor 506 is mounted on the lower end of the lifting shaft 504. The lifting motor 502 is a servo motor for driving the cutting motor 506 to move up and down.

[0045] A method for automatically removing bags from mushroom sticks, comprising the following steps:

[0046] S1: The belt conveyor 100 first conveys the mushroom sticks to the drum line 400. The mushroom sticks entering the drum line 400 first hit the travel switch 901 and fall into the groove of the drum line 400. After the controller obtains the signal from the travel switch 901, it controls the pusher device 200 to move, and the pusher device 200 pushes the mushroom sticks to feed;

[0047] S2: When the mushroom stick is pushed to the position of the photoelectric switch 705 by the pushing device 200, the pushing device 200 pauses. At this time, the end of the mushroom stick is exposed from the gap between the two blocking plates 704. Then the controller controls the lifting mechanism and the cutting motor 506 to start. The descending cutting disc 505 cuts the end of the mushroom stick. The cut end falls into the mushroom bag collection frame 104. Then the lifting mechanism drives the cutting disc 505 upward to the initial position. Then the cutting motor 506 stops, thereby fully opening the bag mouth.

[0048] S3: The twisting motor 701 drives the two blocking plates 704 to rotate outward 90 degrees, allowing the mushroom sticks to completely pass through the gap between the two blocking plates 704, and then the pushing device 200 pushes the mushroom sticks to move again;

[0049] S4: When the mushroom sticks move to the bag-tearing mechanism 600, the two hooks 603 enter the front end of the bag and hook the bag. As the pushing device 200 continues to push, the bag is removed and the peeled mushroom sticks fall into the mushroom stick collection frame 103.

[0050] S5: After the mushroom bag is peeled off from the mushroom stick, the pushing device 200 and the blocking plate 704 return to their initial positions. Then the controller controls the solenoid valve to start, and compressed air is ejected from the air nozzle 507 to blow the mushroom bag off the hook 603, completing the mushroom stick bag removal process.
