[0040] Considering the following description, these and other features of this specification, as well as the operation and function of the related components of the structure, and the economy of assembly and manufacture of the parts, can be significantly improved. All of these form part of this specification with reference to the accompanying drawings. However, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not drawn to scale.

[0041] During the original milk tea production and packaging process, employees had to manually open and fold the paper trays and dividers. However, the paper trays and dividers were quite rigid, making them difficult to open and fold. The work of opening and folding the paper trays and dividers for a long time was labor-intensive and inefficient.

[0042] like Figure 1 The diagram shows the structure of an automated paper tray opening device. This device includes a frame 1, a storage bin 2, a tray-retrieving assembly 3, an opening assembly 4, a control module 5, and a pressing and shaping assembly 7. The storage bin 2 is located on the frame 1 and stores paper trays 11. The tray-retrieving assembly 3 is located below the storage bin 2 and includes a pusher 31 and a conveying power component 32. The conveying power component 32 drives the pusher 31 to push a single paper tray 11 from the storage bin 2 to the opening area of ​​the opening assembly 4. The opening assembly 4 is located on the frame 1 in front of the storage bin 2 and is used for folding and shaping the paper tray 11. The pressing and shaping assembly 7 moves downwards to shape the paper tray 11, preventing it from springing back and deforming. The control module 5 is connected to the tray-retrieving assembly 3, the opening assembly 4, and the pressing and shaping assembly 7 to control their operation. Once the paper tray 11 is delivered to the correct position, the opening component 4 pulls open the paper tray 11, and then the pressing and shaping component 7 presses it down to shape it, thus completing the folding action. The tray removal component 3 can also push the opened paper tray 11 out of the entire device, realizing automated opening of the paper tray 11.

[0043] like Figure 2The diagram shows a schematic of the paper tray opening assembly 4. This assembly includes a first suction assembly 41 and a second suction assembly 44. The first suction assembly 41 is located above the opening area, and the second suction assembly 44 is located below the opening area. The first suction assembly 41 includes a first suction cup assembly 42 and a first driving member 43. The first driving member 43 controls the first suction cup assembly 42 to suction the paper tray 11. The second suction assembly 44 includes a second suction cup assembly 45 and a second driving member 46. The second driving member 46 drives the second suction cup assembly 45 to suction and fix the paper tray 11. After the first suction cup assembly 42 and the second suction cup assembly 45 suction the paper tray 11, they move away from each other to open the paper tray 11.

[0044] The first driving component 43 includes a first driving cylinder, which is fixedly connected to the frame 1 via a first driving component support 434. The first adsorption assembly 41 further includes a fixed support 433, a connecting plate assembly 432, and a first mounting plate 421. The connecting plate assembly 432 includes a first connecting plate 4320 and a second connecting plate 4321 arranged in parallel. The fixed support 433 is fixedly connected to the frame 1. The first mounting plate 421 is rotatably connected to the fixed support 433 via the first connecting plate 4320 and the second connecting plate 4321. The first suction cup assembly 42 is disposed on the first mounting plate 421. The output end of the piston rod of the first driving cylinder is rotatably connected to the first connecting plate 4320. The piston rod of the first driving cylinder drives the first connecting plate 4320, the second connecting plate 4321, and the first mounting plate 421 to rotate, thereby driving the first suction cup assembly 42 to move obliquely. In the connecting plate assembly 432, both ends of the first connecting plate 4320 and the second connecting plate 4321 are rotatably connected to the fixed support 433 and the first mounting plate 421 via connecting shaft 431. In this embodiment, the connecting shaft 431 is connected by a pin.

[0045] It should be noted that, in order to improve stability and power output, in this embodiment, there are two of each of the first driving member 43, fixed support 433, and connecting plate assembly 432, which are symmetrically arranged relative to the first mounting plate 421. It is understood that, in another embodiment, the first driving member 43, fixed support 433, and connecting plate assembly 432 can be configured as one, with a connecting rod assembly or similar component provided on the other side of the driving member to achieve rotation of the first mounting plate 421.

[0046] It should be noted that, given the shape of the paper tray 11, if the first suction cup assembly 42 and the second suction cup assembly 45 are attached and fixed, vertical movement will damage the paper tray 11. Therefore, the first suction cup assembly 42 is moved at an angle to avoid damage to the paper tray 11.

[0047] To accommodate different paper tray thicknesses, the first suction assembly 41 also includes a suction cup mounting plate 4211 and a connecting rod 4210. The first suction cup assembly 42 is mounted on the suction cup mounting plate 4211. The suction cup mounting plate 4211 is connected to the first mounting plate 421 via the connecting rod 4210. The distance between the suction cup mounting plate 4211 and the first mounting plate 421 can be adjusted by adjusting the connecting rod 4210.

[0048] The second driving component 46 includes a second driving cylinder, the second adsorption component 44 includes a second mounting plate 451, and the second suction cup component 45 is disposed on the second mounting plate 451. The second driving cylinder drives the second mounting plate 451 to move the second suction cup component 45 upward to achieve adsorption and fixation of the paper tray 11.

[0049] The control module 5 sends an action signal, causing the positioning cylinder 471 to move the positioning baffle 472 upward, completing the positioning action of the paper tray 11. Further, the second driving member 46 moves upward, and the second suction cup assembly 45 adsorbs the paper tray 11, fixing it to prevent displacement, while simultaneously providing a downward pulling force during the opening action of the paper tray 11. Further still, the first driving member 43 retracts, driving the first mounting plate 421 via the connecting plate assembly 432 and the connecting shaft 431, causing the first suction cup assembly 42 to move obliquely downward to adsorb the upper surface of the paper tray 11. Further still, the first driving member 43 pushes out, causing the first suction cup assembly 42 to move obliquely upward, providing an upward pulling force to open the paper tray 11, thereby opening the paper tray 11. The pressing and shaping assembly 7 then moves downward, completing the shaping of the paper tray 11 and preventing it from easily springing back and deforming.

[0050] In this embodiment, both the first suction cup assembly 42 and the second suction cup assembly 45 are provided with multiple suction cups. The multiple suction cups provide stronger suction force when adsorbing the paper tray 11, preventing the paper tray 11 from detaching from the suction cup assembly. Specifically, the first suction cup assembly 42 has six double-layer suction cups arranged in two rows: two suction cups in the first row and four suction cups in the second row. This arrangement of rows with an uneven number of suction cups in each row facilitates lifting and securing the paper tray 11 when the first suction cup assembly 42 moves at an angle. The second suction cup assembly 45 has four single-layer suction cups. It is understood that the number and distribution of suction cups can be varied according to the size and type of the paper tray 11.

[0051] To ensure that the paper tray 11 is accurately placed in the tray opening area, the tray opening assembly 4 also includes a positioning assembly 47. The positioning assembly 47 includes a positioning cylinder 471, a positioning baffle 472, and a positioning support frame 473. The positioning support frame 473 is mounted on the frame 1, the positioning cylinder 471 is mounted on the positioning support frame 473, and the positioning baffle 472 is mounted at the output end of the positioning cylinder 471. The positioning cylinder 471 drives the positioning baffle 472 to rise and fall to position the paper tray 11 located in the tray opening area.

[0052] likeFigure 3 The diagram shows the conveying and picking structure of the paper tray 11. The picking assembly 3 includes a pusher 31, a conveying power unit 32, and a positioning detection photoelectric sensor. The conveying power unit 32 drives the pusher 31 to push a single paper tray 11 to the opening area, and the positioning detection photoelectric sensor detects whether the paper tray 11 has been pushed to the opening area.

[0053] The conveying power component 32 includes a conveying cylinder, and the pick-up assembly 3 also includes a conveying guide shaft 34, a push support 35, and a push base 36. The push support 35 is mounted on the frame 1. There are two push supports 35, which are connected by the conveying guide shaft 34. The push base 36 is sleeved on the conveying guide shaft 34. The pusher 31 is mounted on the push base 36. The conveying cylinder is mounted on the push support 35. The piston rod of the conveying cylinder is connected to the push base 36, driving the push base 36 to move on the conveying guide shaft 34, thereby driving the pusher 31 to push the paper tray 11.

[0054] The pusher 31 also includes a pusher baffle 311, a pusher bracket 37, and a material-picking power component 33. The pusher bracket 37 is mounted on the pusher base 36, and the material-picking power component 33 is mounted on the pusher bracket 37. The pusher baffle 311 is connected to the output end of the material-picking power component 33, and the material-picking cylinder drives the pusher baffle 311 to move vertically. The material-picking power component 33 controls the extension height of the pusher baffle 311 to facilitate the ejection of the paper tray 11. The material-picking power component 33 selects the material-picking cylinder.

[0055] The tray-discharging assembly 6 includes a discharge stop lever 61, a discharge power component 62, and a discharge bracket 63. The discharge bracket 63 is located at the end of the push base 36 away from the push bracket 37. The discharge power component 62 is mounted on the discharge bracket 63. The discharge stop lever 61 is connected to the output end of the discharge power component 62, and the discharge power component 62 drives the discharge stop lever 61 to move vertically. The tray-opening assembly 4 has a slide 64 at the front, through which the discharge stop lever 61 discharges the opened paper tray 11.

[0056] The discharge power unit 62 controls the extension height of the discharge stop lever 61 to facilitate the discharge of the paper tray 11. The discharge power unit 62 selects the discharge cylinder.

[0057] To improve the space utilization and working efficiency of the tray opening device, the device also includes a storage bin 2. This storage bin 2 includes baffles 21, anti-detachment baffles 22, and photoelectric sensors. There are at least four baffles 21, which surround and form a placement area for the paper trays 11. The four baffles 21 bind and arrange the paper trays 11. Two anti-detachment baffles 22 are located at the lower ends of the two baffles 21 at the rear of the storage bin 21. These baffles reduce the downward pressure on the paper trays 11 due to gravity, ensuring that only one paper tray 11 enters the pusher 31 at a time from the storage bin 2, and preventing the next paper tray 11 from entering the pusher 31. This achieves the purpose of separating the paper trays 11, facilitating automatic tray retrieval. The photoelectric sensors are located on the frame 1 and are used to detect whether the storage bin 2 is empty.

[0058] Upon receiving an action signal, the paper tray 3 and the paper tray discharge assembly 6 simultaneously activate the material handling power component 33 and the discharge power component 62, driving the paper tray 11 towards the opening area. The positioning photoelectric sensor detects the activation of the paper tray 3 and the paper tray discharge assembly 6 and sends feedback to the control module 5. Further, the control module 5 sends a positioning signal, activating the positioning cylinder 471 to assist in positioning the paper tray 11. Further still, the second drive component 46 activates to attract the bottom of the paper tray 11, providing a downward pulling force to open it. Further still, the first suction component 41 moves diagonally downwards, pulling the paper tray 11 open. Further still, the pressing and shaping component 7 presses down to shape the paper tray, and finally, the paper tray 11 is discharged by the paper tray discharge assembly 6, completing the automatic opening process of the paper tray 11.
