[0010] Such as Figures 1 to 4As shown, an automatic bag supply mechanism for edible mushroom bag production equipment includes, from front to back in the order of conveying mushroom bags, a bag embryo roller 1 for clamping the bag embryo (embryo belt disk), a conveying roller group for guiding the conveying direction of the embryo belt, a driving pair of rollers for driving the embryo belt to move, a heat sealing device for plastic-sealing the bottom of the mushroom bag, and an opening device for opening the mouth of the mushroom bag. The driving pair of rollers is composed of a fixed roller 2 and a movable roller 3 that are arranged in parallel and can rotate freely. The fixed roller 2 is horizontally arranged and connected to the driving device ( The movable roller 3 is arranged above the fixed roller 2 so as to be movable up and down, and is pressed against the fixed roller 2 by the pressing device to clamp the embryonic strip and drive the embryonic strip to move forward. The heat sealing device includes a pair of heat sealing blocks 4, a pair of auxiliary blocks 5 and a pressure plate 6. The heating component of the heat sealing device is arranged on the heat sealing block 4. The heat sealing block 4 and the auxiliary block 5 each include a fixed block and a movable block. The movable block is arranged above the fixed block and fixed at the bottom of the pressure guide rod 7. The pressure plate 6 is arranged above the movable block The pressure guide rod 7 is slidably connected to the pressure plate 6 through the guide rod sleeve. A pressure spring is sleeved between the guide rod sleeve and the dynamic pressure block on the pressure guide rod 7. The pressure of hot pressing and pressing the embryo strip is provided by the pressure spring. The pressure plate 6 is connected to the frame through the guide rod 8, the guide rod sleeve and the reset spring. The pressure plate is provided with rising power by the reset spring. A cutting knife 9 for cutting the embryo strip into a single mushroom bag is provided between the heat sealing pressure block 4 and the auxiliary pressure block 5. It is fixedly connected to the pressure plate 6 through the knife rod. Driving the pressure plate can drive the dynamic pressure block to move downward. After the process of compacting and heat-sealing the embryo belt is completed, the cutting knife simultaneously cuts off the heat-sealed part from the position where the pressing block is tightened. The opening device includes a fixed suction cup 10 and a movable suction cup 11. The movable suction cup 11 is fixed above the fixed suction cup 10. The upper and lower surfaces of the heat-sealed and cut mushroom bag mouth are sucked by the fixed suction cup 10 and the movable suction cup 11 respectively. The movable suction cup 10 opens the bag mouth upward, and the finger of the bagging manipulator extends into the bag mouth to support the mushroom bag from the inside and transfer it to the feeding port of the automatic bagging mechanism of the mushroom chaff. The bag rolled into a disc shape is clamped on the bag roller. The free end of the bag is stretched out and bypasses the conveying roller group in turn, and is clamped by the driving roller. When the roller rotates, the embryo belt is pulled forward, and it is heat-sealed and cut by the heat sealing device. The length of the finished mushroom bag is controlled by the number of revolutions of the motor driving the fixed roller, and can also be controlled by setting a photoelectric sensor or other methods.
[0011] The bag embryo roller 1 is driven by a motor. The bag embryo is actively released by the motor.
[0012] The conveying roller group includes a fixed buffer roller 12 and a dynamic buffer roller 13. The fixed buffer roller 12 is fixedly connected to the frame, and the dynamic buffer roller 13 is fixed on the slider and connected to the frame through the slider and a vertically arranged slide bar. The embryo belt is zigzag-shaped and wound between the fixed buffer roller 12 and the dynamic buffer roller 13. Position sensors for detecting the upper and lower limit positions of the dynamic buffer roller 13 are provided at the conveying roller group. The driving roller pulls the embryo belt to move forward, and the tensioned embryo belt pulls the slider upward. When the slider slides to the upper limit position, the upper position sensor sends a signal, and the control device starts the motor to release the embryo belt, and stops at the lower limit position.
[0013] The blade of the cutting knife 9 is serrated. The embryonic strip can be easily cut by pressing down.
[0014] The clamping device includes a transverse slide, a support beam 14 and a guide wheel 15. The transverse slide is fixedly connected to the frame. The support beam 14 is provided with a guide surface. The support beam 14 is horizontally arranged and connected to the transverse slide through a slider. The guide wheel 15 is matched and connected to the guide surface of the support beam 14 and connected to the movable roller 3 of the driving roller pair through a bracket. When the support beam 14 slides horizontally, the guide wheel 15 is driven to move up and down through its guide surface, thereby driving the movable roller 3 of the driving roller pair to move up and down (a guide or limiting component is provided so that the movable roller can only move in the up and down direction). The guide surface can be composed of two horizontal planes and a middle inclined plane. The inclined plane is used to move the guide wheel, and the plane is used to stop the guide wheel. The matching relationship between the guide surface and the guide wheel can be the following two types: 1. The guide surface can be made into a groove shape to clamp the guide wheel. 2. The guide wheels are arranged up and down to clamp the guide surfaces on both sides of the support beam. Slide the joist to move the driving roller upwards, put the embryo belt in and then move it back to the joist. Press the guide wheel down through the joist to make the driving roller clamp the embryo belt.
[0015] The opening device is driven by a screw drive device, which includes a vertical guide rail, a driving screw, a motor and a connecting plate 16. The vertical guide rail is fixedly connected to the frame, the driving screw is arranged parallel to the vertical guide rail and connected to the motor, the connecting plate 16 is slidably connected to the vertical guide rail through a slider, and the connecting plate 16 is also connected to the driving screw through a threaded connection part, and the movable suction cup 11 of the opening device is fixedly connected to the connecting plate 16. The motor drives the screw to rotate to drive the threaded connection part and the connecting plate to slide up and down along the vertical guide rail, thereby driving the movable suction cup to move up and down.
[0016] The pressure plate 6 of the heat sealing device is driven by the connecting plate 16, and the connecting plate 16 is provided with an extension extending above the pressure plate 6. When the pressure plate 6 drives the suction cup 11 to move downward, the pressure plate 6 is pressed downward. The bag is cut and the suction cup is attached to the upper and lower surfaces of the bag while the bag is heat sealed. When the suction cup moves upward, the bag mouth opens naturally under the action of negative pressure.
[0017] A conveying device 17 is provided between the heat-sealing device and the opening device for connecting the constant-pressure block for connecting the heat-sealing press block 4 and the constant suction cup 10 of the opening device. The upper surface of the conveying device travels synchronously with the embryo belt, which is smoother than setting up a flat plate connection.
[0018] The conveying device 17 includes a driving roller and a driven roller, and the driving roller is connected to the driving counter-roller by a number of annular rubber rings. Since the bacteria bags are light and have a certain stiffness, the conveyor belt of the conveying device can use multiple rubber rings to support the bacteria bags. Annular grooves are preset on the surfaces of the driving roller and the driven roller for positioning the rubber rings.
