[0029] When the bag is received, the bag receiving and releasing mechanism moves to the bag sealing and fixing device side with the spread mechanical arm. When the mechanical arm moves to the bag sealing and fixing device, the bag openings on both sides are closed together. Then, the pressing arm rotates downward to press the bag opening of the garbage bag on the heat sealing device of the barrel port side wall. The heat sealing device heats to seal the bag opening. Then, the clamping jaw and the clamping plate release the clamping edge of the garbage bag opening. The bag receiving and releasing mechanism resets to wait for the next bagging work. The garbage bag after heat sealing waits for manual removal from the garbage bag.

[0030] The present application can automatically complete the bagging, receiving and packaging work after the first placement of the roll-shaped garbage bag. Only the garbage bag needs to be taken away after packaging is completed. The work of bagging and receiving and packaging is saved, which is more convenient and sanitary. The present application uses point-disconnection type roll garbage bags, which are pre-placed and do not need to be heat sealed at the bottom during packaging and bagging. The leakage problem that may exist in the heat sealing of the bag bottom on site is avoided, and the safety and reliability are higher. BRIEF DESCRIPTION OF DRAWINGS

[0075] First, the roll-shaped breakpoint bag 9 is placed into the bag storage box 22 of the bag storage and feeding device 2, and then the head of the bag is pulled out from the opening of the bag storage box 22 to the bag feeding roller device 21. The opening and closing mechanism 25 of the bag feeding roller device 21 drives the left and right two groups of roller support 212 to separate, so that the bag can pass between the left and right two rollers 211. After passing through the left and right two rollers 211, the bag reaches the bag opening pre-stretching device 23, and then the bag opening flange 91 is set on the pre-stretching device 23. The pre-stretching device 23 slightly stretches the bag opening, and after the bag 9 is placed, the opening and closing mechanism 25 closes the left and right two groups of roller support, and at this time the left and right rollers 211 clamp the bag 9.

[0076] Next, the lifting drive device 54 of the bag storage and feeding mechanism 5 drives the lifting seat 53 to descend, so that the clamping jaw of the mechanical arm 51 moves to the lower side of the bag opening flange. Then the lifting drive device 54 rises so that the flange 91 is set on the clamping jaw, and the clamping jaw clamps the bag opening. After clamping the bag opening, the rotating drive device 52 drives the mechanical arm 51 to open to both sides, and the mechanical arm 51 expands the bag opening to both sides.

[0077] Then, the bag storage and feeding mechanism 5 moves along the guide rail to the side of the bag sealing and fixing device 3 under the drive of the walking drive motor 73. During the bag feeding process, the left and right rollers 211 rotate to cooperate with the bag storage and feeding mechanism 5 to slowly feed out the bag 9. When the expanded bag opening is sent to the side of the bag sealing and fixing device 3, the clamping plate 3 of the bag sealing and fixing device 5 closes to fix the bag opening on the side. Then the clamping jaw of the mechanical arm releases the clamped bag opening, and the bag storage and feeding mechanism 5 resets. During the resetting process, the mechanical arm 51 rotates synchronously and slowly resets to the initial position, and the clamping jaw of the mechanical arm 51 is always in the flange. After the mechanical arm 51 resets to the initial position, the clamping jaw clamps the bag opening at the other end of the bag. Then the rotating drive device 52 drives the mechanical arm 51 to rotate outward again to expand the other end of the bag. The rear part of the roll-shaped bag is clamped by the left and right rollers. During the expansion of the bag, the connecting point of the bags is automatically disconnected under the action of tension, and the next bag opening is formed at the bag opening pre-stretching device. After the mechanical arm 51 expands to both sides, the bag opening is completely opened. When the bag opening is expanded, it will pull the connecting point of the adjacent bag, so that the connecting point is disconnected. Then, through suction, blowing or manual pressing, the lower part of the bag is expanded in the barrel and the bagging work is completed.

[0078] The present application first places the bag and the garbage packing is completed by manual bagging. The whole bagging and heat sealing packing are automatically completed by the machine, which saves the operation process of bagging and packing, is more convenient and sanitary, and avoids the leakage problem of on-site heat sealing of the bag bottom.

A method of dispensing a bag for an automatic bag dispensing and packing trash can, the method comprising: Firstly, the breakpoint garbage bag in a roll shape is placed into the garbage bag storage box of the bag storage and sending device, then the head of the garbage bag is pulled out from the opening of the garbage bag storage box and sent to the bag sending roller device, the opening and closing mechanism drives the left and right roller support frames of the bag sending roller device to separate, so that the garbage bag can pass between the left and right rollers of the bag sending roller device, after passing through the left and right rollers, the garbage bag reaches the bag opening pre-stretching device, the bag opening of the garbage bag is provided with a clamping edge, the both ends of the clamping edge are not closed, the clamping edge of the bag opening of the garbage bag is separated left and right after passing through the pre-stretching device, and after the garbage bag is placed, the opening and closing mechanism is reset to make the left and right roller support frames closed, so that the left and right rollers can clamp the garbage bag; Next, the chuck of the mechanical arm of the bag receiving and releasing mechanism clamps the clamping edge of the bag opening of the garbage bag. After clamping the bag opening, the mechanical arm rotates to spread the bag opening to both sides. Next, the bag receiving and releasing mechanism moves along the guide rail to the side of the bag sealing and fixing device under the drive of the translation drive device. The spread bag opening is sent to the side of the bag sealing and fixing device. During the bag sending process, the left and right rollers driven by the roller drive device rotate to cooperate with the bag receiving and releasing mechanism to slowly send out the garbage bag. When the spread bag opening is sent to the side of the bag sealing and fixing device, the clamping plate of the bag sealing and fixing device fixes the spread bag opening on this side. Next, the clamping jaw of the mechanical arm releases the clamped bag opening, and the bag receiving and releasing mechanism resets. After the mechanical arm resets to the starting position, it clamps the slightly stretched clamping edge of the other end of the garbage bag. Then the mechanical arm rotates outward again and spreads the bag opening of the other end of the garbage bag. Since the rear of the roll of garbage bags is clamped by the left and right rollers, the connecting points between the garbage bags are automatically disconnected under the action of tension when the garbage bags are spread, and the next clamping edge of the garbage bag is formed at the bag opening pre-stretching device. After the mechanical arm opens to both sides, the garbage bag opening is completely opened.

When the bag is received, the bag receiving and releasing mechanism moves to the side of the bag sealing and fixing device with the spread mechanical arm. When the mechanical arm moves to the bag sealing and fixing device, the bag openings on both sides are closed together. Then the pressure arm rotates downward to press the bag opening of the garbage bag on the heat sealing device on the side wall of the barrel opening. The heat sealing device heats to seal the bag opening. Then the clamping jaw and the clamping plate release the clamping edge of the garbage bag opening. The bag receiving and releasing mechanism resets to wait for the next bagging work. The heat-sealed garbage bag waits for manual removal from the garbage bag.
