[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] The utility model discloses a lifting and reciprocating cup pushing device for a paper cup packaging machine, which is mainly applicable to the scenario where the cup pushing assembly in the existing paper cup packaging machine only adopts an ordinary telescopic cylinder to push the cup, and the conveyor belt needs to be paused to wait for it to be retracted, resulting in a sluggish production process and reduced efficiency.

[0021] Reference Figure 1 and Figure 2, a lifting and reciprocating cup pushing device of a paper cup packaging machine includes: a support 8, the upper sides of multiple supports 8 are fixedly connected to the same conveying bin 3, the interior of the conveying bin 3 is rotatably connected with a rotating shaft 1 through a bearing at equal intervals, and the outer walls of the two rotating shafts 1 are provided with the same cup strip conveyor belt 10; a rotating motor 2, fixedly connected to the outer side of one end of the conveying bin 3, and the driving end of the rotating motor 2 is connected to one end of one of the rotating shafts 1 through a coupling; a lifting platform 6, fixedly connected to the outer side of the end of the conveying bin 3 away from the rotating motor 2, and the lifting platform 6 and the rotating motor 2 are located on the same side of the conveying bin 3; a cup pushing assembly 7, arranged on the outer side of the end of the conveying bin 3 close to the lifting platform 6, and the cup pushing assembly 7 is used to push multiple groups of paper cups on the cup strip conveyor belt 10 onto the lifting platform 6; a detection assembly 9, used to detect whether the cup pushing part in the cup pushing assembly 7 is bent and correct it within a certain bending limit.

[0022] Reference Figure 1-Figure 3 In a preferred embodiment, the cup pushing assembly 7 includes: a support frame 701, which is fixedly connected to the outer side of one end of the conveying bin 3 close to the lifting platform 6, and rotating holes are opened at equal intervals on both sides of the support frame 701. The insides of the two rotating holes are respectively connected to rotating shafts 703 through bearings, and the outer walls of the two rotating shafts 703 are provided with the same transmission belt 704; a driving motor 702, which is fixedly connected to the outer wall of the support frame 701 away from the transmission belt 704, and the driving end of the driving motor 702 is connected to one end of one of the rotating shafts 703 through a coupling.

[0023] In this solution, the push cup assembly 7 also includes: a fixed plate 705, which is connected to the outer wall of the transmission belt 704 by bolts. The fixed plate 705 can move back and forth horizontally with the rotation of the transmission belt 704. The lower side of the end of the fixed plate 705 away from the transmission belt 704 is fixedly connected to a connecting block 706.

[0024] In this embodiment, the cup pushing assembly 7 also includes: a lifting cylinder 707, which is fixedly connected to the lower side of the end of the connecting block 706 away from the fixed plate 705, and the telescopic end of the lifting cylinder 707 passes through the connecting block 706 and is fixedly connected to the connecting plate 708, and the end of the connecting plate 708 away from the connecting block 706 is fixedly connected to the cup pushing plate 709.

[0025] When using the lifting and reciprocating cup pushing device of the paper cup packaging machine, the connecting plate 708 can be lifted and reciprocated to push the cup under the action of the transmission belt 704 and the lifting cylinder 707 set in the cup pushing component 7. During this process, the connecting plate 708 can avoid the cup strips conveyed by the cup strip conveyor belt 10 to prevent interference between the conveyor belt and the cup strips, which can enable the cup strip conveyor belt 10 to move earlier and improve production efficiency.

[0026] Reference Figure 1-Figure 5In a preferred embodiment, the detection component 9 includes: a connecting seat 901, multiple connecting seats 901 are fixedly connected to both sides of the conveying bin 3 at relatively equal intervals, and multiple connecting seats 901 are provided with detection cylinders 904, and the telescopic ends of every two opposite detection cylinders 904 are fixedly connected to the same support plate 902, and the two support plates 902 are respectively located on both sides of the connecting plate 708; an electric telescopic rod 903, and the two electric telescopic rods 903 are respectively fixedly connected to the lower side of one end of the two support plates 902 close to the lifting cylinder 707.

[0027] In this scheme, the detection component 9 also includes: a detection sensing bin 905, the two detection sensing bins 905 are respectively fixedly connected to the telescopic ends of the two electric telescopic rods 903; a limiting extrusion bin 907, which is slidably connected to the inside of the limiting slide grooves opened on both sides of the detection sensing bin 905, and the limiting extrusion bin 907 is located inside the detection sensing bin 905. A trigger block 906 is provided on the lower side of the limiting extrusion bin 907, and a plurality of rotating grooves are opened at equal intervals on both sides of the inner wall of the limiting extrusion bin 907. The interiors of the plurality of relative rotating grooves are respectively connected with pressure wheels 908 through bearings, and the pressure wheels 908 are in contact with the connecting plate 708 of the push cup assembly 7 for detecting bending; an extrusion spring 909, one end of the plurality of extrusion springs 909 is fixedly connected to the lower side of the limiting extrusion bin 907 at equal intervals, and the other end of the plurality of extrusion springs 909 is fixedly connected to the inner wall of the lower end of the detection sensing bin 905.

[0028] When using the lifting and reciprocating cup pushing device of the paper cup packaging machine, the multiple pressure wheels 908 in the detection component 9 continuously squeeze the lower ends of both sides of the movable connecting plate 708 under the action of the squeezing spring 909. If the connecting plate 708 is bent to a certain limit after long-term operation, it can slowly return to straightness through the continuous squeezing of the pressure wheel 908 without affecting the work. If the connecting plate 708 is bent beyond the limit, the limit squeezing bin 907 overcomes the elastic force of the squeezing spring 909 and continues to descend under the action of the bent connecting plate 708. When the trigger block 906 touches the detection sensing bin 905, it means that the connecting plate 708 is bent to a state where it cannot work normally. The worker immediately stops working and inspects the bent part.

[0029] Reference Figure 1 and Figure 2 In a preferred embodiment, U-shaped observation rods 4 are fixedly connected to both sides of the conveying bin 3 at equal intervals. Rotating slots are respectively provided on the upper sides of the two U-shaped observation rods 4. Hand-cranked sensors 5 are rotatably connected to the inside of the rotating slots through bearings. The two hand-cranked sensors 5 are always located on the upper side of the cup strip conveyor belt 10.

[0030] When the lifting and reciprocating cup pushing device of the paper cup packaging machine is used, the hand-cranked sensor 5 can be used to control the empty conveying position between cups of different numbers in a program as required.

[0031] Working principle: When using the lifting and reciprocating cup pushing device of the paper cup packaging machine, the front-end machine first stacks the produced disposable cups into a cup according to the specified number and then pushes them into the conveying position on the cup conveyor belt 10. When the hand-cranked sensor 5 on the U-shaped observation rod 4 detects that there are cups on the conveying position, the rotating motor 2 is turned on to drive the rotating shaft 1 to rotate, thereby controlling the cup conveyor belt 10 to move forward one conveying position. In this process, the hand-cranked sensor 5 can be used to control the empty conveying position between different rows of cups according to the program as needed; when several rows of cups need to be packaged and transported to the cup pushing area, the drive motor 702 is turned on to drive the rotating shaft 703 to rotate slowly clockwise, and the transmission belt 704 rotates along the clockwise rotating rotating shaft 703. Under the action of the air filter 705, the fixed plate 705 moves horizontally toward the conveying bin 3. During this process, the cup pushing plate 709 is fixed at one end of the connecting plate 708 to push the required cup strips on the cup strip conveyor belt 10 to the lifting platform 6, and then the required cup strips are conveyed to the next area through the lifting platform 6. When the required cup strips leave the conveying bin 3, the lifting cylinder 707 is controlled to lift the connecting plate 708. When the connecting plate 708 leaves the upper side of the cup strip conveyor belt 10 and reaches the maximum height, the detection cylinder 904 and the electric telescopic rod 903 are controlled to make one end of the two detection sensing bins 905 respectively abut against the outer walls of both sides of the connecting plate 708. At the same time, the multiple pressure wheels 908 in the limiting extrusion bin 907 roll against the lower sides of the outer walls of both sides of the connecting plate 708. When the connecting plate 708 is bent to a certain extent under the action of the squeezing spring 909, it can slowly return to its original position without affecting the work. If the connecting plate 708 is bent beyond the limit, the limit squeezing bin 907 will overcome the elastic force of the squeezing spring 909 and continue to decline under the action of the bent connecting plate 708. When the trigger block 906 touches the detection sensor, the contact between the connecting plate 708 and the conveying bin 705 is completed. When the connecting plate 708 is in a state of bending and unable to work normally, the worker immediately stops working and inspects the bent part. When the connecting plate 708 is normal, after the inspection of the connecting plate 708 is completed, the two detection sensing bins 905 are moved away from the connecting plate 708 by controlling the detection cylinder 904 and the electric telescopic rod 903. When the connecting plate 708 is retracted under the action of the transmission belt 704, the lifting cylinder 707 contracts, and finally the connecting plate 708 is reset, the previous work is repeated. During the resetting process of the connecting plate 708, the cup strip conveyor belt 10 is still running. When the cup pushing assembly 7 is just reset, the required cup strips have been transported to the cup pushing area, and the cup pushing work can be carried out quickly to improve production efficiency.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
