[0017] As shown in the figure, the plastic cup and paper cup counting, weighing and packaging machine disclosed in this utility model includes a feeding conveyor belt group and a packaging component 4 arranged in sequence. A weighing component 5 is provided at the discharge end of the packaging component 4. The packaging component is a common device on the market used to package stacked cups with outer plastic bags. It belongs to the prior art and is not the innovation of this application, so it will not be described in detail. The weighing component 5 is a common structure with electronic weighing sensors, which is existing technology and will not be described in detail. It has an inclined feed rack 1 at the feed end of the corresponding feeding conveyor belt group, a counting sensor 18 on the movement path of the feeding conveyor belt group, and a baffle plate 10 at the discharge end of the corresponding feeding conveyor belt group. The counting sensor 18 is positioned close to the baffle plate 10, which is connected to a moving drive component. It also includes a pusher plate 11, which is connected to the moving drive component, driving the pusher plate 11 to rise, fall, and move. The pusher plate 11 can push the material on the feeding conveyor belt group into the packaging component 4. A discharge conveyor belt 6 is provided at the discharge end of the weighing component 5, with a material distribution arm 8 corresponding to the discharge conveyor belt 6. A finished product lifting seat 7 is provided on one side of the discharge conveyor belt 6, and a defective product lifting seat 15 is provided on the other side. The finished product lifting seat 7 and the defective product lifting seat 15 are connected to the piston rods of corresponding cylinders to achieve the lifting drive of the two lifting seats.
[0018] The feeding conveyor belt assembly includes a first feeding conveyor belt 2 and a second feeding conveyor belt 3 arranged front and rear, with a feeding rack 1 corresponding to the first feeding conveyor belt 2. Using this structure, two-stage conveying of the cups can be achieved. The moving speeds of the first and second feeding conveyor belts can be adjusted to the required values according to the feeding and subsequent stacking speeds, thereby better realizing the conveying and stacking of the cups.
[0019] Furthermore, the moving drive assembly includes a first cylinder 9, the piston rod of which is connected to the baffle plate 10. The movable drive assembly includes a second cylinder 14, the piston rod of which is connected to the movable seat 13. A third cylinder 12 is mounted on the movable seat 13, and the piston rod of the third cylinder 12 is connected to the pusher plate 11. By controlling the first cylinder 9, the baffle plate 10 can be moved; by controlling the second cylinder 14, the pusher plate 11 can be moved; and by controlling the third cylinder 12, the pusher plate 11 can be raised or lowered.
[0020] Furthermore, one end of the material distribution swing arm 8 is connected to the rotating shaft 16, and the rotating shaft 16 is connected to the rotating part of the rotary cylinder. By controlling the rotary cylinder to drive the rotating shaft 16 to rotate, the material distribution swing arm 8 can be driven to swing. Of course, a motor can also be used to drive the rotating shaft 16 to rotate, thereby driving the material distribution swing arm 8 to swing.
[0021] Furthermore, two material distribution swing arms 8 are arranged on the left and right sides, one near the finished product lifting seat 7 and the other near the defective product lifting seat 15. By setting two material distribution swing arms, corresponding movement on both sides can be achieved.
[0022] Furthermore, the tops of the finished product lifting seat 7 and the defective product lifting seat 15 are provided with inclined surfaces, and baffle portions 17 are provided on one side of each of the finished product lifting seat and the defective product lifting seat. With the above structure, when the cup is delivered to the finished product lifting seat or the defective product lifting seat, the corresponding lifting seat is controlled to rise. Because its top has an inclined surface, the cup rests against the baffle portion 17 during its upward movement. Subsequently, as the cup rises above the baffle portion 17, it will fall into the corresponding collection or transfer component under the guidance of the inclined surface for cup collection or transfer operations.
[0023] The working principle of this utility model is as follows: The cup falls onto the first conveyor belt 2 via the feeding rack 1, and then is fed onto the second feeding conveyor belt 3 at a suitable speed. During the cup conveying process, the counting sensor counts the number of cups. When the counting sensor 18 detects that the number of cups has reached the set value, it will send feedback information to the controller. The controller will then control the baffle 10 to block the subsequent cups being conveyed. Next, it will control the pusher 11 to push the required number of cups into the packaging component 4 for packaging. After packaging, the cups are sent to the weighing component 5 for weighing (the weighing component 5 is equipped with common structures such as conveyor belts or pusher blocks to deliver the materials). After packaging is complete... The finished cups are conveyed by the discharge conveyor belt 6. If the weight information fed back to the controller by the weighing component 5 meets the requirements, the controller controls the material distribution arm 8 corresponding to the finished product lifting seat 7 to swing above the discharge conveyor belt 6. As the material comes into contact with the material distribution arm 8, the material distribution arm 8 swings again to push the material onto the finished product lifting seat 7, and controls the finished product lifting seat 7 to lift and send the material out. If the weight information fed back to the controller by the weighing component 5 does not meet the requirements, the controller controls the material distribution arm corresponding to the defective product lifting seat 15 to swing above the discharge conveyor belt 6. As the material comes into contact with the material distribution arm 8, the material distribution arm 8 swings again to push the material onto the defective product lifting seat 15, and controls the defective product lifting seat 15 to lift and send the material out.
[0024] This invention, through the combination of a counting sensor, a pusher plate, and a baffle plate, enables automated counting, stacking, and pushing of cups, replacing the traditional manual stacking method. This effectively reduces the labor intensity of workers and improves the quality and speed of cup stacking. In addition, by combining a weighing component, a material distribution arm, a finished product lifting seat, and a defective product lifting seat, the invention enables weighing and detection of cups after packaging, ensuring the equipment's weighing and detection, as well as the separate conveying of finished and defective products, effectively improving the yield rate of products after production output.
