[0051] Example 2

[0052] The working principle of this utility model:

[0053] First, before automatically adding products, perform manual preparation:

[0054] Before automatic production or sales, preparation work must be done. When the conditions are met, the addition work of automatic production and automatic sales begins. The top 5-round stick-shaped plastic bag heads of the 4-pre-packaged plastic hanging bags containing food are manually placed into the 72-aisles in sequence by manual methods. The 72-aisles can store 5 pieces of 4-pre-packaged plastic hanging bags 4, but not limited to 5 pieces. According to the design requirements, the 8-food or food auxiliary materials in the 4-pre-packaged plastic hanging bags are classified and manually filled, and then the 4-pre-packaged plastic hanging bags are transported to their respective 72-aisles for standby use. Then the utility model is connected to the power supply, and all electrical appliances are normal and ready for work;

[0055] All of the following are completed in full automatic operation:

[0056] When food needs to be added, the production equipment or vending machine sends a start work instruction to the electrically connected PLC industrial computer of the utility model. After receiving the production instruction signal, the relevant electrical and mechanical components are controlled to work. The PLC industrial computer is electrically connected to the 19-reduction motor, and is energized in the forward direction. The working power of the output shaft of the 19-reduction motor is transmitted through the 17-driving sprocket, the 15-chain and the 16-driven sprocket. The 15-chain drives the 13-slider A to move. The components installed on the 13-slide A will move horizontally to the 72-cargo aisle required to be added. When the 72-cargo aisle is accurately aligned, the 14-limit switch set on the 11-slide rail A sends a signal to the PLC industrial computer. After receiving the signal, the PLC industrial computer cuts off the power to the 19-reduction motor. The above components and moving components stop moving and wait for receiving the goods.

[0057] The PLC industrial computer is electrically connected to energize the 62-cargo lane reduction motor in the forward direction. The power of the 62-cargo lane reduction motor is moved through the 63-cargo lane reduction motor sprocket, the 65-cargo lane chain, the 69-cargo lane slider, the 70-inner pusher connector and the 71-inner pusher in the direction of the 11-slide rail A. The 71-inner pusher moves in the 72-cargo lane to push all the 4-pre-packaged plastic hanging bags toward the 11-slide rail A. When the front end of the first 4-pre-packaged plastic hanging bag touches the 28-touch stop switch, a signal is sent to the PLC industrial computer to control the 62-cargo lane reduction motor to cut off the power, and the relevant moving parts stop moving. At this time, a 4-pre-packaged plastic hanging bag has been parked in the lower opening tubular conveying member composed of the 23-tubular lower opening at the 22-swing arm that can open the movable tube wall and the 77-tubular lower opening semicircular tube wall, waiting to move.

[0058] The PLC industrial computer reversely energizes the 19-reduction motor through electrical connection. The working power of the 19-reduction motor drives the 13-slider A and the 21-tubular lower opening fixing frame and the tubular conveying component to move horizontally to the 40-cutting back plate through the transmission action of the 17-driving sprocket, the 16-driven sprocket and the 15-chain. The PLC industrial computer cuts off the power of the 19-reduction motor through electrical connection and waits for the cut plastic bag to be unpacked.

[0059] The PLC is electrically connected to 33-electric push rod to energize in the forward direction, and the 33-electric push rod extends the power through the 35-second connecting component and the 31-knife holder, 36-knife arm, 37-knife shaft and 38-roller blade, and at the 40-cutting back plate, the 38-roller blade and the 40-cutting back plate simultaneously roll and cut the 10-cutting line on the plastic bag, cut the plastic bag and unseal the plastic bag at the same time. At this time, the food in the plastic bag cannot move downward due to the fixed wrapping of the plastic bag and the viscosity of the food material itself, and keeps a stable state waiting for the next action. The plastic bag edge material cut off by the 38-roller blade falls freely into the 42-waste recycling box due to its gravity to complete the edge material recovery work. The plastic bag edge material cut off by the 38-roller blade falls freely into the 42-waste recycling box due to its gravity to complete the edge material recovery work.

[0060] The PLC is electrically connected to energize the 19-reduction motor in the forward direction. The working power of the 19-reduction motor drives the 13-slider A and the 21-tubular lower opening fixed frame through the 17-driving sprocket, the 16-driven sprocket and the 15-chain. The 23-tubular lower opening opens and the movable tube wall moves horizontally to the 28-touch stop switch. At this time, the plastic bag contacts the 54-scraping fixed back plate. The PLC is electrically connected to energize the 49-scraper swing reduction motor in the forward direction to control the 53-scraper to swing to press the plastic bag. When the PLC controls the 49-scraper swing reduction motor to cut off the power, the 53-scraper will stop. The plastic bag is pressed down by the anti-swinging, and the PLC energizes the 47-lifting electric push-pull rod in the forward direction through the electrical connection. The 47-lifting electric push-pull rod extends the working power to drive the 49-scraper swing reduction motor, 50-coupling, 51-shaft frame, 52-scraper shaft and 53-scraper to move downward, and cooperate with the 54-scraping fixed back plate to squeeze and push the food in the plastic hanging bag to move downward to the opening until the food is squeezed to the specified position to complete the adding work. The PLC energizes the 47-lifting electric push-pull rod in the reverse direction through the electrical connection, and all the actions involved in the adding work return to complete the single adding work.
