[0026] The following is combined with Figure 1-5 The utility model is further described.

[0027] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: it includes a pillow packaging machine body 1, a first conveyor belt 2 is provided in the pillow packaging machine body 1, the first conveyor belt 2 is used to convey the packaged food from the pillow packaging machine body 1, and a support platform 10 is provided on one side of the first conveyor belt 2, a slide rod 11 is slidably installed in the support platform 10, and a flat plate 9 is fixedly connected to the top of the slide rod 11, and a rejection platform 3 is fixedly installed on one side of the support platform 10, a crank 17 is rotatably installed on the rejection platform 3, a ring 13 is provided on the crank 17, a connecting column 18 is slidably installed in the ring 13, the connecting column 18 is fixedly connected to the upper end of the crank 17, and a push rod 14 is fixedly connected to one side of the ring 13.

[0028] The pillow packaging machine body 1 packages the food, and the first conveyor belt 2 outputs the packaged food from the pillow packaging machine body 1. The packaged food is transported to the flat plate 9 via the first conveyor belt 2. The crank 17 provided on the rejection table 3 on one side of the support table 10 rotates, and the crank 17 drives the connecting column 18 to rotate. The connecting column 18 moves in the middle groove of the ring 13 to push the ring 13 to move. The ring 13 drives the push rod 14 to move, and the push rod 14 moves to push the packaged food away from the flat plate 9.

[0029] It is further explained that a tooth 19 is fixedly mounted on the outer surface of the slide rod 11, a gear 20 is meshed with one side of the tooth 19, a rotating shaft 21 is fixedly connected to one end of the gear 20, a worm 22 is fixedly mounted on the end of the rotating shaft 21 away from the gear 20, a worm wheel 23 is meshed with one side of the worm 22, a connecting rod 24 is fixedly connected to the upper end of the worm wheel 23, and the upper end of the connecting rod 24 is fixedly connected to the bottom of the crank 17.

[0030] The teeth 19 and the gear 20 are arranged inside the rejection platform 3, the rotating shaft 21 is rotatably arranged inside the rejection platform 3 and the support platform 10, and the interior of the rejection platform 3 is provided with an installation space for the worm 22 and the worm wheel 23. The connecting rod 24 is rotatably installed inside the rejection platform 3. After the packaged food is transported to the flat plate 9 (the processed food is moon cakes, rice dumplings, etc. with a larger weight), the weight of the food drives the flat plate 9 to move downward, and the flat plate 9 drives the teeth 19 to move downward through the slide rod 11. Since the teeth 19 are engaged with the gear 20, the teeth 19 drive the gear 20 to rotate, and the gear 20 drives the worm 22 to rotate through the rotating shaft 21. The gear 20 is engaged with the worm wheel 23, and the worm 22 drives the worm wheel 23 rotates, the worm gear 23 drives the crank 17 to rotate through the connecting rod 24, and the crank 17 pushes the push rod 14 through the connecting column 18 and the collar 13, and the push rod 14 pushes the packaged food from the flat plate 9; when the first conveyor belt 2 conveys an empty package containing no food, the empty package is light and cannot press down the flat plate 9, so the empty package remains on the flat plate 9, and the food package subsequently conveyed by the pillow packaging machine body 1 will push the empty package retained on the flat plate 9 away, thereby realizing automatic rejection of the empty package, avoiding the need for manual inspection of the packaged food to reject the empty package, and at the same time, being able to stably reject the empty package without omission, thereby avoiding adverse effects caused by the empty package being sent to the customer.

[0031] It is further explained that the outer movable sleeve of the slide rod 11 is provided with a return spring 12, the upper end of the return spring 12 is fixedly connected to the bottom of the flat plate 9, and the lower end of the return spring 12 is fixedly connected to the upper surface of the support platform 10.

[0032] As the plate 9 moves downward, the return spring 12 is compressed. After the push rod 14 pushes the packaged food away from the plate 9, the compressed return spring 12 drives the plate 9 to move upward to restore the initial state. The automatic return spring 12 realizes the automatic return of the plate 9, thereby improving the automation level of the device.

[0033] It is further explained that a limiting groove 15 is provided at the bottom of the push rod 14 , a limiting block 16 is slidably installed in the limiting groove 15 , and the limiting block 16 is fixedly installed on the rejecting platform 3 .

[0034] The limiting block 16 cooperates with the limiting groove 15 to guide and limit the movement of the push rod 14, preventing the connecting column 18 from driving the ring 13 to rotate, improving the stability of the push rod 14 when moving, and thus improving the overall stability of the device during use.

[0035] It is further explained that a conveying platform 7 is fixedly connected to a side of the support platform 10 away from the push rod 14 , and a second conveyor belt 8 is provided on the conveying platform 7 .

[0036] The conveyor platform 7 provides installation conditions for the second conveyor belt 8. The push rod 14 pushes the packaged food from the flat plate 9 to the second conveyor belt 8. The second conveyor belt 8 transports the packaged food to the packaging station, thereby improving the efficiency of food processing and packaging.

[0037] It is further explained that a placement table 4 is fixedly connected to the side of the support platform 10 away from the pillow packaging machine body 1 , a collection box 5 is placed on the placement table 4 , and an inclined plate 6 is fixedly installed on the collection box 5 .

[0038] The empty packages remain on the flat plate 9 due to their light weight. As the first conveyor belt 2 conveys, the subsequent packaged food pushes away the empty packages remaining on the flat plate 9, and the empty packages fall onto the inclined plate 6 and fall along the inclined plate 6 into the collection box 5 for collection.

[0039] The specific operation is as follows: the first conveyor belt 2 outputs the packaged food from the pillow packaging machine body 1, and the packaged food is transported to the flat plate 9 via the first conveyor belt 2. The weight of the food drives the flat plate 9 to move downward, and the flat plate 9 drives the teeth 19 to move downward through the slide bar 11. The teeth 19 drive the gear 20 to rotate, and the gear 20 drives the worm 22 to rotate through the rotating shaft 21. The worm 22 drives the worm wheel 23 to rotate, and the worm wheel 23 drives the crank 17 to rotate through the connecting rod 24. The crank 17 is connected to the connecting column 18 and the ring 13. The push rod 14 is pushed, and the push rod 14 pushes the packaged food from the flat plate 9 to the second conveyor belt 8. The second conveyor belt 8 transports the packaged food to the packaging station. When the first conveyor belt 2 transports the empty package to the flat plate 9, the empty package cannot drive the flat plate 9 to move downward due to its light weight and remains on the flat plate 9. As the first conveyor belt 2 transports, the subsequent packaged food pushes away the empty package remaining on the flat plate 9, and the empty package falls onto the inclined plate 6 and falls along the inclined plate 6 into the collection box 5 for collection, thereby realizing automatic rejection of the empty package.
