Detailed Implementation
[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments. Specific experimental conditions and methods not specified in the following embodiments are generally conventional methods well known to those skilled in the art.
[0026] Example 1: A lid-dispensing device for packaging bowls, comprising a shelf 1, a vertical through-slot 2 extending through the shelf 1, multiple limiting rods 3 fixedly connected to the top of the shelf 1 on the outside of the through-slot 2, multiple stacked packaging lids 4 on the inside of the limiting rods 3, a pressing device 5 on one side of each packaging lid 4, and a storage frame 6 fixedly connected to the top of the inner side of the shelf 1 below each packaging lid 4. A discharge bending plate 7 is fixedly connected to one side of the storage frame 6, and the storage frame 6 is located away from the discharge bending plate 7. A pusher trough 8 is provided on one side of the storage frame 6, and a pusher device 9 is provided on one side of the pusher trough 8. An air pump 10 is fixedly connected to the bottom of the storage frame 6. A connecting hose 11 is fixedly connected to one side of the air pump 10. A suction cup 12 that is vertically aligned with the discharge bending plate 7 is fixedly connected to the end of the connecting hose 11 away from the air pump 10. A connecting plate 13 is fixedly connected to the bottom of the suction cup 12. The output shaft of a servo motor 14 is fixedly connected to one end of the connecting plate 13. The output shaft of an electric cylinder 15 is fixedly connected to the top of the servo motor 14.
[0027] The storage frame 6 is located below the through groove 2 and vertically aligned with the through groove 2. The packaging cover 4 at the bottom is located inside the storage frame 6. The electric cylinder 15 is fixedly connected to the top of the shelf 1. The output shaft of the electric cylinder 15 passes through the shelf 1 and is slidably connected to the shelf 1. The pushing device 9 includes a fixed plate 91 fixedly connected to the top of the inner side of the shelf 1. A cylinder 92 is fixedly connected to one side of the fixed plate 91. The output shaft of the cylinder 92 passes through the fixed plate 91 and is slidably connected to the fixed plate 91. A pushing block 93 is fixedly connected to one end of the output shaft of the cylinder 92. The pushing block 93 is inserted into the inner side of the pushing groove 8.
[0028] Example 2: As Figure 1-7 As shown, the difference between the lid-separating and lid-dropping device for packaging bowls described in this embodiment and the device described in Embodiment 1 is only that: the pressing device 5 includes a vertically arranged sliding rod 51 fixedly connected to the top of the shelf 1, a sliding plate 52 is provided on the outside of the sliding rod 51, a through hole 53 is provided inside the sliding plate 52, a rubber block 54 is fixedly connected to the bottom of the sliding plate 52 on one side of the through hole 53, a counterweight block 55 is fixedly connected to the top of the sliding plate 52 above the rubber block 54, the sliding rod 51 is inserted into the inside of the through hole 53, and the rubber block 54 is located at the center of the top of the uppermost packaging lid 4 and fits tightly with it. Through the setting of the pressing device 5, sliding rod 51, sliding plate 52, through hole 53, rubber block 54 and counterweight block 55, the counterweight block 55 can drive the sliding plate 52 to move during the falling process of the packaging lid 4, thereby continuously pressing the packaging lid 4 and preventing the packaging lid 4 from getting stuck;
[0029] The end of the connecting plate 13 away from the servo motor 14 is rotatably connected to a slide block 16. A vertically arranged auxiliary support rod 17 is slidably connected to the inner side of the slide block 16. The top end of the auxiliary support rod 17 is fixedly connected to the top end of the inner side of the shelf 1. Through the slide block 16 and the auxiliary support rod 17, when the suction cup 12 moves, the slide block 16 slides on the outside of the auxiliary support rod 17, thereby making the movement of the connecting plate 13 more stable and avoiding its tilt, which would cause the movement trajectory to be distorted.
[0030] Below the suction cup 12 is a storage plate 18. Multiple storage slots 19 are arranged in a polar axis on the outer side of the storage plate 18. Packaging bowls 20 are placed inside the storage slots 19. A rotating base 21 is installed at the center of the bottom end of the storage plate 18. The storage slots 19 below the suction cup 12 are vertically aligned with the suction cup 12. Through the storage plate 18, storage slots 19, packaging bowls 20 and rotating base 21, the packaging bowls 20 can be transferred after the lids are separated, so that the unseparated packaging bowls 20 can be moved under the suction cup 12, ensuring the feeding speed.
[0031] The method of using the lid-separating and lid-dropping device for packaging bowls described in this embodiment is as follows:
[0032] Before use, power on the device and connect the device to the external controller. First, place the stacked packaging covers 4 in multiple limiting rods 3. The packaging covers 4 are of the same size and do not fit together. The bottom packaging cover 4 passes through the through groove 2 on the shelf 1 and enters the storage box 6. Then, place the slide plate 52 outside the slide rod 51, so that the slide rod 51 is inserted into the through hole 53 and the rubber block 54 is moved to the top of the top packaging cover 4. During the fall of the packaging cover 4, the counterweight 55 can drive the slide plate 52 to move, thereby continuously pressing the packaging cover 4 and preventing the packaging cover 4 from getting stuck.
[0033] Next, place the packaging bowl 20 into the storage slot 19 on the storage plate 18. Use the controller to start the various components of the equipment. First, start the pushing device 9. The output shaft of the cylinder 92 on the fixed plate 91 extends and drives the pushing block 93 to move in the pushing slot 8, so that the bottom packaging cover 4 moves into the discharge bending plate 7 and to the top of the suction cup 12. At the same time, the pushing block 93 is located below the other packaging covers 4. Then, start the air pump 10. The air pump 10 sucks out the air from the suction cup 12 through the connecting hose 11, so that the suction cup 12 adsorbs the packaging cover 4. The next step is to start the electric cylinder 15 and the servo motor 14. The output shaft of the servo motor 14 drives the connecting plate 13 and the packaging cover 4 to rotate, so that the opening of the packaging cover 4 faces downward. The output shaft of the electric cylinder 15 extends and drives the servo motor 14 and its connecting components to move, so that the slide 16 slides outside the auxiliary support rod 17 until the packaging cover 4 moves to the top of the packaging bowl 20. Finally, the air pump 10 is turned off and the rotating base 21 is started, so that the placement plate 18 rotates until the other packaging bowl 20 moves to the bottom of the suction cup 12. At the same time, the electric cylinder retracts 15 to reset the servo motor 14 and other structural components. At the same time, the servo motor 14 rotates in the opposite direction to reset the connecting plate 13 and the suction cup.
[0034] Repeat the above operation to continuously seal the packaging bowl 20. The design of the auxiliary support rod 17 and the slide 16 makes the movement of the connecting plate 13 more stable and avoids its tilting, which would cause the movement trajectory to be distorted. The design of the pushing device 9 and its connecting components can ensure that only a single packaging lid 4 is taken out each time, which reduces the lid separation error rate and improves work efficiency.
[0035] This utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
