[0002] Existing cleaning robots all use manually controlled trash cans. When the trash cans are full, they need to return to the garbage station to call on cleaners to participate in subsequent processing, such as dumping and manually packing the garbage. This cannot completely free up people's hands and is inefficient. Summary of the Invention

[0003] To address the problems of existing technologies, this invention provides a heat-sealing and cutting mechanism for garbage bags and its operating method.

The heating component is installed inside a base plate, and the drive roller is installed on the lower end face of the base plate, distributed on the same side as the heating component, and rotates around its own axis. A base plate and a driven roller are mounted on the X-axis component. The base plate and the driven roller follow the displacement of the X-axis component to achieve displacement from the outside to the inside of the base plate. When the X-axis component moves to the innermost side, the drive roller and the driven roller abut against each other, forming a cutting area between the base plate and the heating component.

[0005] In a further improvement, the housing includes a side sealing plate and a top cover. The side sealing plate surrounds the garbage bag sealing and cutting mechanism, and the top cover covers the side sealing plate and the top of the garbage bag sealing and cutting mechanism.

Rotating the handle tightens the outer heat insulation cloth.

[0009] The present invention also provides an operating method for the above-mentioned heat-melting based garbage bag sealing and cutting mechanism, comprising the following steps: 1) Before each sealing and cutting, the pressure plate moves toward the heating component, gathers the garbage bag, the lower active roller and driven roller come into contact, the first spring is compressed, the active roller drives the driven roller to rotate together, and moves the garbage bag downward; 2) During sealing and cutting, the pressure plate moves toward the heating component, the lower elastic strip on the pressure plate presses the heating wire, the heating wire is energized to perform the cutting operation, the upper elastic strip presses the heating strip, the heating strip is energized to perform the sealing operation; 3) After separation and cutting, the pressure plate moves away from the heating component. There is a gap between the lower elastic strip and the heating wire. The upper elastic strip presses the heating strip under the pressure of the second spring. The active roller drives the driven roller to rotate together. After cutting, the garbage bag is separated into an upper garbage bag and a lower garbage bag.

The active end synchronous pulley 3-2-5 and the driven end synchronous pulley 3-2-15 are respectively mounted on the output shaft of the active end linear module 3-2-1 and the driven end linear module 3-2-16. Power is transmitted through the second synchronous belt 3-2-8. The first synchronous belt tensioning mechanism 3-2-10 and the second synchronous belt tensioning mechanism 3-2-11 tension the second synchronous belt 3-2-8. The motor reducer 3-2-3 is mounted on the motor reducer mounting plate 3-2-4. The motor reducer mounting plate 3-2-4 is mounted on the base plate 3-3. The active synchronous pulley 3-2-6 is mounted on the output shaft of the motor reducer 3-2-3. Power is transmitted to the active end synchronous pulley 3-2-5 through the first synchronous belt 3-2-7. The pressure plate 3-2-2 spans across the active end linear module 3-2-1 and the driven end linear module 3-2-16 and is mounted on it. The pressure plate can slide along its straight line.

The upper part of the front of pressure plate 3-2-2 has an upper elastic strip fixing seat 3-2-21, on which multiple sets of guide columns 3-2-20 are fixed. A second spring 3-2-19 is provided in the middle. Multiple sets of guide holes are provided at corresponding positions of pressure plate 3-2-2.

The lower part of pressure plate 3-2-2 has a lower elastic strip 3-2-17 installed at the bottom.

[0018] like Figure 6 , 7As shown in Figure 8, the heating assembly 3-1 includes a heating element mounting plate 3-1-1, a heating element support tube 3-1-2, a heating element mounting post 3-1-3, a heating wire 3-1-4, a heating strip 3-1-5, an inner heat insulation cloth 3-1-6, an outer heat insulation cloth 3-1-7, a heat insulation cloth roller mounting seat 3-1-8, a handle 3-1-9, a heat insulation cloth roller 3-1-10, and a plunger 3-1-11. The heating element mounting plate 3-1-1 is fixed to the base plate 3-3.

The inner heat insulation cloth 3-1-6, heating wire 3-1-4, and heating strip 3-1-5 are attached to these tubes. The inner heat insulation cloth 3-1-6 is attached to the inner heat insulation cloth 3-1-6, and the two ends are fixed to the heating element mounting posts 3-1-3. The four heating element mounting posts 3-1-3 are respectively insulated and installed at both ends of the heating element mounting plate 3-1-1. The heating wire 3-1-4 and the heating strip 3-1-5 are covered with the outer heat insulation cloth 3-1-7.

The outer heat insulation cloth 3-1-7 is tightened by rotating the handle 3-1-9.

[0019] The present invention also provides an operation method for a garbage bag sealing and cutting mechanism based on heat fusion: like Figure 9 As shown, in the bag-pulling state, after each garbage filling, there may be garbage or sewage in the bag in the sealing area that may affect sealing and cutting. Therefore, before each sealing and cutting, the pressure plate 3-2-2 moves towards the heating component 3-1 to gather the garbage bag. The lower active roller 3-11 and driven roller 3-2-12 come into contact, the first spring 3-8 is compressed, and there is still a gap between the upper garbage bag 4 and the heating component 3-1. The active roller 3-11 drives the driven roller 3-2-12 to rotate together, moving the garbage bag downwards. This allows a new garbage bag to be pulled out of the garbage bag box.

[0020] like Figure 10 As shown, in the sealing and cutting state, the pressure plate 3-2-2 continues to move towards the heating component 3-1. The lower elastic strip 3-2-17 and the upper elastic strip 3-2-18 respectively press the heating wire 3-1-4 and the heating strip 3-1-5. The lower heating wire is energized to perform the cutting operation, and the upper heating strip is energized to perform the sealing operation.

[0021] like Figure 10As shown, the garbage bag is in the state after separation and cutting. The pressure plate 3-2-2 moves away from the heating component 3-1. There is a gap between the lower elastic strip 3-2-17 and the heating wire 3-1-4. The upper elastic strip 3-2-18 presses the heating strip 3-1-5 under the pressure of the second spring 3-2-19. The active roller 3-11 drives the driven roller 3-2-12 to rotate together. After cutting, the garbage bag is separated into an upper garbage bag 4-1 and a lower garbage bag 4-2. At this time, the bottom of the upper garbage bag 4-1 is sealed. The lower garbage bag 4-2 is simultaneously cut and sealed under the action of the heating wire 3-1-4.
