[0002] Paper plates, as a type of disposable or recyclable tableware, are widely used in catering, takeout, parties, and fast-moving consumer goods scenarios. Their design focuses on being lightweight, environmentally friendly, and low-cost, meeting short-term use needs.

[0003] A search revealed an existing paper tray forming machine, such as the paper feeding device disclosed in CN220519487U. This device uses a suction head to hold the paper tray, and under the action of a solenoid valve, the paper tray detaches from the suction head. The blower agitates the surrounding airflow, blowing the detached paper tray onto a collection platform, thus completing the paper tray conveying process. However, in actual operation, because the paper tray is relatively light, it easily scatters on the collection platform or even falls to the ground, making paper tray collection troublesome and causing dust to easily accumulate on the ground. Therefore, this paper tray forming machine paper feeding device is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems that paper trays are light and easily scatter on the collection platform or even fall to the ground, making paper tray recycling troublesome and causing paper trays that fall to the ground to easily get dusty. Therefore, a paper feeding device for a paper tray forming machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-5 A paper feeding device for a paper tray forming machine includes a support plate 1, a mounting frame 2 fixedly connected to the top of the support plate 1, a rectangular plate 3 fixedly connected to one side of the mounting frame 2, and a conveyor belt 4 mounted on the mounting frame 2. The conveyor belt 4 is rotated at a uniform speed by a drive mechanism on the mounting frame 2 to convey the paper trays that fall onto the conveyor belt 4.

[0023] A rectangular shell 5 is fixedly connected to the bottom of the support plate 1. A gear 6 and a rack 7 are installed inside the rectangular shell 5. A placement plate 8 is installed above the support plate 1. A collection box 9 is placed on the placement plate 8. A lifting mechanism is installed inside the rectangular shell 5 to adjust the height of the collection box 9 on the placement plate 8 through the gear 6 and the rack 7. The lifting mechanism allows the collection box 9 placed on the placement plate 8 to be close to the conveyor belt 4, so that the paper trays on the conveyor belt 4 can fall accurately into the collection box 9.

[0024] A receiving cavity is provided on one side of the collection box 9, and a sliding plate 10 is slidably connected inside the receiving cavity, allowing the sliding plate 10 sufficient space to move up and down.

[0025] The lifting mechanism includes a rotating rod 12 mounted and rotatably connected to one side of the rectangular shell 5. One end of the rotating rod 12 is fixedly connected to the gear 6. A partition 13 is fixedly connected to the inner wall of the rectangular shell 5. The partition 13 has a first rectangular opening 14. One side of the rack 7 is in contact with one side of the partition 13. The rack 7 meshes with the gear 6. The rotating rod 12 allows the gear 6 to rotate at a uniform speed. The gear 6 then drives the rack 7 on one side of the partition 13 to move up and down.

[0026] A trapezoidal block 15 is fixedly connected to one side of the rack 7, and a sliding rod 16 is fixedly connected to the inner wall of the rectangular shell 5. A sliding block 17 is slidably connected to the sliding rod 16. A contact plate 18 is fixedly connected to one side of the sliding block 17. One end of the contact plate 18 abuts against the hypotenuse of the trapezoidal block 15. When the rack 7 rises, it drives the trapezoidal block 15 to rise within the first rectangular opening 14. Subsequently, the trapezoidal block 15 drives the contact plate 18, which abuts against its hypotenuse, to rise. The contact plate 18 then drives the sliding block 17 to slide upward along the sliding rod 16.

[0027] A second rectangular opening 19 is provided on one side of the rectangular shell 5. A connecting plate 20 is fixedly connected to one side of the sliding block 17. The connecting plate 20 is located inside the second rectangular opening 19. One end of the connecting plate 20 is fixedly connected to the placement plate 8. The sliding block 17 causes the connecting plate 20 connected to it to move upward inside the second rectangular opening 19, thereby causing the placement plate 8, which is fixedly connected to one end of the connecting plate 20, to move upward, thereby driving the collection box 9 above the placement plate 8 to rise.

[0028] The trapezoidal block 15 is attached to the first rectangular opening 14 on both sides. The support plate 1 has a first through hole and a second through hole. The rack 7 is located in the first through hole, and the connecting plate 20 is located in the second through hole. The first through hole allows the rack 7 to extend above the support plate 1 when it rises, so as to avoid the support plate 1 from blocking the rack 7. The second through hole allows the two ends of the connecting plate 20 to rise and fall normally while connecting the sliding block 17 and the placement plate 8. At the same time, the bottom of the rectangular shell 5 has a third through hole, so that when the rack 7 falls, it can extend to the bottom of the rectangular shell 5 to ensure the normal operation of the device.

[0029] The placement plate 8 has a placement slot, and the collection box 9 is located in the placement slot. The placement slot prevents the collection box 9 from shaking back and forth on the placement plate 8 and ensures that the collection box 9 is located directly below the conveyor belt 4.

[0030] A spring 21 is fixedly connected inside the receiving cavity. One end of the spring 21 is fixedly connected to the sliding plate 10. A limiting plate 22 is fixedly connected to the collecting box 9. The lower end of the conveyor belt 4 is installed between two rectangular plates 3. The top of the sliding plate 10 abuts against the bottom of the rectangular plate 3. One end of the conveyor belt 4 extends into the interior of the collecting box 9. When the lifting mechanism drives the collecting box 9 to rise, the top of the sliding plate 10 contacts the bottom of the rectangular plate 3. As the collecting box 9 continues to rise, the spring 21 contracts, and the sliding plate 10 retracts into the receiving cavity until one end of the conveyor belt 4 enters the collecting box 9, allowing the paper trays on the conveyor belt 4 to fall accurately into the collecting box 9. After collection, the collecting box 9 is lowered. Under the elastic action of several springs 21, the sliding plate 10 moves out of the receiving cavity and locks onto one side of the limiting plate 22, blocking the paper trays inside and facilitating transportation.

[0031] The collection box 9 is hinged to a top cover 23, and a handle is fixedly connected to the top cover 23. When the paper tray needs to be removed after being transported to a suitable location, the paper tray can be completely poured out by using the handle to open the top cover 23.

[0032] The lifting mechanism also includes a drive motor 11 installed on one side of the rectangular shell 5. The specific model and specifications of the drive motor 11 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The working principle of this utility model:

[0034] The collection box 9 is placed into the placement slot. Then, the drive motor 11 drives the rotating rod 12 to rotate. The rotating rod 12 drives the gear 6 to rotate. The gear 6 drives the rack 7, which meshes with it, to rise. The rack 7 drives the trapezoidal block 15 in the first rectangular opening 14 to rise. The trapezoidal block 15 drives the contact plate 18 to rise. The contact plate 18 drives the sliding block 17 to move upward along the sliding rod 16. The sliding block 17 drives the connecting plate 20 to rise in the second rectangular opening 19. The connecting plate 20 drives the placement plate 8 above the support plate 1 to rise. The placement plate 8 then drives the collection box 9 to rise. When the top of the sliding plate 10 contacts the bottom of the rectangular plate 3, the collection box 9 continues to rise. The spring 21 contracts, and the sliding plate 10 retracts into the receiving cavity until one end of the conveyor belt 4 enters the collection box 9, allowing the paper tray on the conveyor belt 4 to fall accurately into the collection box 9.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
