Description

Technical Field

[0001] The utility model relates to the technical field of paper cup and paper bowl forming and processing, in particular to an automatic circle placing machine for paper cup lids. Background Art

[0002] After the emergence and popularization of paper cups and paper bowls, in order to further reduce the use of plastics, the demand for paper cup covers gradually emerged. The existing technology for the production of paper cup covers is roughly as follows: the paper cup cover is divided into two parts, a paper ring and a round paper piece, and processed separately. Then, the paper ring and the paper cup cover are combined into one paper cup cover by curling the paper ring.

[0003] After the paper rings are cut, they cannot be stacked in order due to their limited thickness. The paper rings even partially overlap and cannot be directly used for continuous production. When faced with the technical requirements for placing paper rings, conventional placement equipment cannot meet the requirements because paper rings are very soft and light materials. For example, the utility model patent with announcement number CN220787071U discloses an automatic ring placing device that uses a reciprocating screw and a push plate to push a single sealing ring to a conveyor belt. If the device is used for automatic paper ring placement, the paper rings are too thin to be stacked in an orderly manner in the discharge barrel like sealing rings, and the function cannot be achieved. Another idea is to use a clamping device, but the clamping device may cause indentations on the paper rings, increasing the defective rate. Utility Model Content

[0008] Further, the separation component includes a height limiting plate;

[0009] To prevent the paper ring from falling off at the feeding hopper and the separation component, side plates can also be arranged on the frame.

[0010] In order to arrange the separated single paper rings one by one, the technical solution provided by the utility model includes: a deviation correction plate is provided;

[0011] Furthermore, the static plate of the deflection correcting plate is connected to a long hole slider, the frame is provided with screw holes, the static plate and the frame are connected through the long hole slider and bolts, and the distance between the two plate surfaces of the deflection correcting plate can be adjusted by adjusting the card slot and the bolts;

[0012] In order to prevent multiple paper rings from moving together and being deformed and stuck in front of the deviation-correcting plate, the technical solution provided by the utility model includes: adding an intermittent horizontal pushing component on the outer side of the moving plate;

[0013] Furthermore, one end of the movable plate of the deflection correction plate is connected to a spring, the other end of the spring is connected to a frame, the other end of the movable plate is provided with a push rod, the driving shaft of the push rod is connected to the motor, and the middle of the movable plate is connected to the frame through a rotating shaft;

DETAILED DESCRIPTION

[0022] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] Embodiment 1

[0024] like Figure 1 and Figure 2 , an automatic paper cup lid placing machine, comprising a frame 1, on which a feeding hopper 2, a separation component 5, a correction plate 3 and a conveyor belt 4 are arranged in sequence, and a side plate 7 is also arranged on the frame 1; the separation component 5 includes a height limiting plate 52; the correction plate 3 has two opposite plate surfaces, wherein a long hole slider 31 is fixed on the static plate 33, and the long hole slider 31 fixes the static plate 33 to the frame 1 through bolts 32 and threaded holes on the frame 1; an intermittent horizontal pushing component 6 is installed on the outer side of the moving plate 34 of the correction plate 3; a rotating shaft 63 is connected to the middle of the outer side of the moving plate 34, one end of which is connected to a push rod 62, and the other end is connected to a spring 61, and the other end of the spring 61 is connected to the frame, and the brush cylinder 51, the conveyor belt 4, the eccentric wheel 64 and the driving shaft of the brush cylinder 51 are all connected to the main shaft of the motor.

[0025] After the paper rings enter the automatic ring placing machine from the feeding hopper 2, they move to the right with the help of the conveyor belt. The height of the unseparated paper rings will be higher than that of a single paper ring due to stacking, and they cannot pass through the gap between the height limiting plate 52 and the conveyor belt smoothly. They are repeatedly processed by the height limiting plate 52 until the paper rings are separated. In order to prevent the paper rings from squeezing each other and getting stuck on the correcting plate 3, the movable plate 34 of the correcting plate 3 will move intermittently through the intermittent transverse pushing component 6. Specifically, the intermittent transverse pushing component 6 includes a spring 61, a rotating shaft 63 and a push rod 62; the push rod 62 will push the movable plate 34 to rotate along the rotating shaft 63. After the rotation is completed, the surface of the correcting plate is reset by the spring 61, and the paper ring continues to move to the right through the conveyor belt 4, thereby achieving the effect of automatic ring placing. The conveyor belt 4 can be connected to an air flow transmission pipe to connect with subsequent processes.

[0026] Embodiment 2

[0027] like Figure 3 and Figure 4, an automatic paper cup lid placing machine, comprising a frame 1, on which a feeding hopper 2, a separation component 5, a correction plate 3 and a conveyor belt 4 are arranged in sequence, the separation component 5 comprises a brush cylinder 51, on which bristles are arranged; the correction plate 3 has two opposite plate surfaces, wherein a long hole slider 31 is fixed on a static plate 33, and the long hole slider 31 fixes the static plate 33 to the frame 1 through bolts 32 and threaded holes on the frame 1; an intermittent horizontal thrust component 6 is installed on the outer side of a moving plate 34 of the correction plate 3; a rotating shaft 63 is connected in the middle of the outer side of the moving plate 34, one end of which is connected to an eccentric wheel 64, and the other end is connected to a spring 61, and the other end of the spring 61 is connected to the frame, and the brush cylinder 51, the conveyor belt 4, the eccentric wheel 64 and the driving shaft of the brush cylinder 51 are all connected to the main shaft of the motor.

[0028] After the paper rings enter the automatic ring placing machine from the feeding hopper 2, they move to the right with the help of the conveyor belt. The height of the unseparated paper rings will be higher than that of a single paper ring due to stacking, and they cannot pass through the gap between the brush cylinder 51 and the conveyor belt smoothly. They are repeatedly processed by the brush cylinder 51 until the paper rings are separated. In order to prevent the paper rings from squeezing each other and getting stuck on the correcting plate 3, the movable plate 34 of the correcting plate 3 will move intermittently through the intermittent transverse pushing component 6. Specifically, the intermittent transverse pushing component 6 includes a spring 61, a rotating shaft 63 and an eccentric wheel 64; the eccentric wheel 64 rotates one circle to cause the movable plate to rotate along the rotating shaft 63. After the rotation is completed, the surface of the correcting plate is reset by the spring 61, and the paper ring continues to move to the right through the conveyor belt 4, thereby achieving the effect of automatic ring placing.

[0029] In order to adapt to paper rings of different sizes, the long hole slider 31 can be adjusted, and the static plate 33 can be further adjusted. After the adjustment is completed, the bolt 32 can be tightened.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, making several improvements and modifications without departing from the technical principle of the present invention should be regarded as within the protection scope of the present invention.
