Bottom plate 1 is provided with a push-pull storage bag drawer for storing garbage bag rolls. The storage bag drawer is arranged behind the bag unfolding box. The bag makes the garbage bag continue to unfold from the folded state along its surface into a "凵" shape. There is a tongue-shaped plate inside the bag expansion box, which is used to pierce the weakened belt between the garbage bags and open the mouth of the next garbage bag. The limiting effect is specifically shown in Figure 5.

The specific working principle of this device is:

Garbage bag rolls are placed in the storage tank behind the push-pull bag-expanding box, and a small part is pre-expanded and fixed with the flaps on the bag-expanding box. After the bag-expanding box is pushed to the designated position, the bag-expanding box can be opened Make the garbage bag continue to unfold from the folded state into a C shape along its surface, preparing for the conveying and bag opening action. The transmission part adopts a double-sided synchronous belt and a steel shaft. Since the friction between the synchronous belt and the garbage bag is greater than the friction between the steel shaft and the garbage bag, when the synchronous belt is running, the garbage bag will be conveyed upwards along with the synchronous belt. until the specified position. The partition mechanism located in the bag opening box stretches out the tongue-shaped plate when the synchronous belt stops running, pierces the weakened belt between the garbage bags and plays a role in limiting the mouth of the next garbage bag. When the user takes out the previous garbage bag When the garbage bag is filled and sealed, the old garbage bag and the new garbage bag will be separated by the tongue-shaped plate along the weakened belt. At this time, the garbage bag is still in a C-shaped unfolded state and enters the next cycle.

The bag opening and sealing mechanism is driven by a 20 biaxial stepping motor, a DC gear motor and four steering gears. Each steering gear is responsible for independently driving a mechanical claw, 20 biaxial stepping motors are responsible for driving the distance between two sets of mechanical claws, and the DC geared motor is responsible for driving the screw to realize the distance between the two mechanical claws on the side away from the stepping motor. distance changes. The garbage bag enters the bag opening area in a C shape along the inner edge of the frame by the transmission partition mechanism. At this time, the two opened mechanical claws on one side are fixed on the same bridge plate and driven by the motor to the other side to open correspondingly. The mechanical claw engages and clamps across the garbage bag and starts to retreat and reset. At this time, due to the structure of the mechanical claw, the friction between the mechanical claw and the surface of the garbage bag is greater than the friction between the two layers of the garbage bag that fits each other. Force, the garbage bag is twisted open and fixed on the two pairs of mechanical claws. With the reset of the mechanical claws on the bridge plate, the garbage bag completes the opening action to unfold into a square and fix it along the inner edge of the frame. The mechanical claws are driven by a separate servo to open and close the two claws. The claws are wrapped with silicone to increase friction. Angle springs are installed at the hinges of the two claws. When the servo opens the claws, it also opens the angle springs. When the two claws mesh During the process of opening the garbage bag, the corner spring is tightened together with the servo to provide sufficient clamping force for the claws, ensuring that the garbage bag can be tightened and fixed by the claws for a long time.

After the garbage bag is full, the motor drives the mechanical claws on both sides to approach again. When the chute sliders on the corresponding pair of mechanical claws are connected, the deceleration motor runs. At the same time, the mechanical claws on the bridge release the garbage bag, and the garbage bag is lifted by the screw The mechanical claws are clamped and tightened in the middle. When the two mechanical claws move to the designated position, the corresponding plastic sealing parts on the two mechanical claws start to operate to complete the sealing action on the closed garbage bags, and the mechanical claws loosen the garbage bags at the same time. After the sealing is completed, the buzzer sounds to remind the user to take away the garbage bag. At the same time, the deceleration motor drives the screw to complete the reset movement of the mechanical claw, and one cycle ends.
