It is an ideal device for producing paper beverage cups, tea cups, coffee cups, advertising paper cups, ice cream cups or other frustum-shaped food containers. In the process of paper cup production and manufacturing, although the paper cup machine has achieved a very high degree of automation, there has been no effective solution for the front-end automatic feeding. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art. The present invention provides an intelligent unmanned feeding device for a paper cup machine, which has a simple structure, reasonable design, stable feeding, high feeding efficiency, effectively reduces labor costs, and can feed paper sheets of multiple specifications at the same time.

[0004] The technical solution adopted by the present invention to solve its technical problems is: an intelligent unmanned feeding device for a paper cup machine, including a transfer bin and a manipulator mechanism. The transfer bin includes a main box body, a transmission component is arranged in the main box body, the output end of the transmission component passes through the main box body and extends to the upper surface of the main box body, and a paper sheet rotating disc is arranged at the end; a plurality of groups of annularly and evenly distributed paper sheet bracket components are evenly arranged on the outer ring of the paper sheet rotating disc; each paper sheet bracket component includes two symmetrically arranged rear baffles, side baffles are arranged on the outer sides of the two rear baffles, fixed paper racks are arranged on the outer ring sides of the two rear baffles facing the paper sheet rotating disc, movable paper racks are arranged on the inner sides of the two fixed paper racks, and a placement groove for placing paper sheets is formed among the rear baffles, side baffles, fixed paper racks and movable paper racks; a humidifying mechanism is further arranged on one side of the transfer bin facing the manipulator mechanism; the manipulator mechanism includes a moving track connecting the transfer bin and the main body of the paper cup machine, a manipulator main body is arranged on the moving track, and an actuator for clamping the paper sheets in the placement groove is arranged at the end of the manipulator main body. The actuator includes a cylinder fixing seat arranged at the end of the manipulator main body, a clamping cylinder is arranged on the cylinder fixing seat, and an upper clamping plate and a lower clamping plate are respectively connected to the upper and lower sides of the clamping cylinder through piston rods. With the above structure, by symmetrically arranging the rear baffles, side baffles, fixed paper racks and movable paper racks, a placement groove for placing paper sheets of different specifications is formed, and a control box is set to control the manipulator mechanism and the transmission component to clamp and feed paper sheets of different specifications. A humidifying mechanism is also set to moisten the paper sheets when the manipulator mechanism feeds the paper sheets, improving the feeding efficiency and reducing the labor cost.

[0005] Preferably, a bin frame is arranged on the upper surface of the main box body outside the paper sheet rotating disc, a bin door is arranged on the bin frame, support universal wheels are arranged at the bottom of the main box body, and a plurality of support wheels are annularly and evenly distributed between the upper surface of the main box body and the bottom surface of the paper sheet rotating disc. The number of the paper sheet bracket components is the same as that of the support wheels. With the above structure, by arranging the bin frame and the bin door, the paper sheets and dust can be effectively separated to ensure the cleanliness of the paper sheets. The support universal wheels can facilitate the movement and parking of the transfer bin, and the support wheels can prevent the paper sheet rotating disc from being deformed due to the different weights of the paper sheets on each paper sheet bracket component, thus affecting the grasping of the paper sheets by the actuator.

[0006] Preferably, the outer side of the rear baffle is connected to the outer side of the fixed paper rack through a connecting plate. Connecting long holes are provided on both sides of the connecting plate. The connecting plate is connected to the rear baffle and the fixed paper rack respectively through the connecting long holes on both sides. A transition groove is provided at the outer ring of the paper sheet rotating disc of the placement groove. The tops of the rear baffle, the side baffle, the fixed paper rack, and the movable paper rack are all bent away from the placement groove. With the above structure, the stability between the rear baffle and the fixed paper rack is improved through the connecting plate. The connecting long holes on both sides of the connecting plate can meet the adjustment of different distances between the rear baffle and the fixed paper rack. The transition groove can be used for the lower clamping plate of the actuator to extend when clamping the lowermost paper sheet. The bending structures at the tops of the rear baffle, the side baffle, the fixed paper rack, and the movable paper rack can effectively improve the convenience of paper sheet placement.

[0007] Preferably, the movable paper rack is rotatably connected to the fixed paper rack through a torsion spring hinge. A rebounder is provided on the side wall of the fixed bracket away from the placement groove through a female head fixing seat. The rebounder is arranged parallel to the side wall of the fixed bracket. A contact head matching the rebounder is provided on the side wall of the movable paper rack away from the placement groove through a mounting seat. The contact head is vertically arranged on the side wall of the movable paper rack. When the movable paper rack is opened, it is fixed by the clamping connection between the contact head and the rebounder. With the above structure, the torsion spring hinge can ensure that the movable paper rack is reset in time after the actuator grabs the paper sheet, avoiding the deviation of the paper sheet on the placement groove. When putting paper sheets into the placement groove, the movable paper rack is fixed in the normally open state by the clamping connection between the contact head and the rebounder, thus facilitating the placement of paper sheets. When closing, just gently press the movable paper rack to separate the contact head from the rebounder, and the movable paper rack automatically closes under the action of the torsion spring hinge.

[0008] Preferably, a rear adjusting plate is provided at the bottom of the rear baffle. Rear mounting long holes are provided on the rear adjusting plate. Rear adjusting slot holes with inner ends extending to both sides of the placement groove are provided on the paper sheet rotating disc relative to the rear adjusting plate. The included angle between the rear adjusting slot holes on both sides of the placement groove is 100° - 110°. The rear baffle is arranged on the paper sheet rotating disc through the rear mounting long holes and the rear adjusting slot holes. A front mounting plate is provided at the bottom of the fixed paper rack. Front mounting long holes are provided on the front mounting plate. Front adjusting slot holes parallel to the outer ring of the paper sheet rotating disc are provided on the paper sheet rotating disc relative to the front mounting plate. The fixed paper rack is arranged on the paper sheet rotating disc through the front mounting long holes and the front adjusting slot holes. With the above structure, the size of the placement groove is adjusted by adjusting the position of the rear baffle on the rear adjusting slot holes and the position of the fixed paper rack on the front adjusting slot holes, so as to realize the placement of paper sheets of different specifications and improve the application range.

[0009] Preferably, the humidifying mechanism includes an atomizing nozzle, a water pump, and a water container. The tail end of the atomizing nozzle is connected to an air pump through an air pipe. The middle section of the atomizing nozzle is connected to the water pump through a first water pipe. The water pump and the water container are connected through a second water pipe. With the above structure, by controlling the water pump and the air pump through the control box, after the water reaches the front end of the atomizing nozzle, the air pump high-pressure atomizes the water and sprays it on both sides of the paper sheet for pre-wetting treatment, which can be started and stopped immediately, avoiding the situation of slippery bottom surface due to dripping water at the equipment site.

[0010] Preferably, the humidifying mechanism further includes a nozzle mounting bracket. The nozzle mounting bracket is arranged on the main box body or the bin rack. The nozzle mounting bracket is provided with an angle adjustment seat with a "D" - shaped structure. The straight side of the angle adjustment seat is connected to the nozzle mounting bracket, and the atomizing nozzle is mounted on the curved side of the angle adjustment seat. With the above structure, the atomizing nozzle adjusts the spraying angle by its position on the curved side of the angle adjustment seat, improving the application range of the atomizing nozzle.

[0011] Preferably, an installation box is provided on the side wall of the main box body. The water pump is arranged in the installation box. The surface of the installation box is provided with a rocker switch for controlling the opening and closing of the water pump. A plurality of water containers are arranged side by side on the side wall of the main box body through a water tank bracket. Adjacent two water containers are connected through a third water pipe.

An industrial camera for sensing the height of the paper sheet in the placing groove is provided on the camera fixing seat. Diffuse reflection switches for sensing whether the grasping position is reached are provided on the upper surface of the end of the upper clamping plate and the upper side of the camera fixing seat. With the above structure, the friction between the upper clamping plate and the lower clamping plate when clamping the paper sheet can be increased by providing reticulations on the lower surface of the upper clamping plate and the upper surface of the lower clamping plate. The end of the lower clamping plate adopting a wedge - shaped structure can ensure that the lower clamping plate can be inserted into the paper sheet without damaging the paper sheet when clamping the paper sheet. By setting the industrial camera and the diffuse reflection switch, the accuracy of the actuator for clamping the paper sheet can be improved.

[0013] Preferably, a control box is further included. The control box is electrically connected to the transmission component, the air pump, the water pump, the driving component, the manipulator main body, the clamping cylinder, the industrial camera, and the diffuse reflection switch.

[0014] When the present invention is in use: 1. Different specifications of paper sheets are placed in the placement slots of the paper sheet bracket assembly; 2. According to the feeding request sent by the paper cup machine lacking materials, the control box identifies the type of cup sheets; 3.
