[0028] like Figures 1-8 The device for producing scald-proof paper bowls shown in the figure includes a frame 1, a climbing conveyor 2 is installed above the frame 1, and a plurality of rubber clips 3 are provided on the outer surface of the climbing conveyor 2 belt. A fixed frame 5 is provided on the outside of one end of the frame 1, and a storage bin 12 is fixedly provided on the outside of the fixed frame 5. Both sides of the storage bin 12 are provided with a mounting mechanism. A lifting cylinder 8 is provided on the top of the mounting mechanism. The telescopic ends of the two lifting cylinders 8 are connected to a movable frame 13 through a set flip member. Two elastic ropes 37 are provided inside the movable frame 13. The outer sides of both ends of the two elastic ropes 37 are provided with a tension reset mechanism. Blocking nets 14 are slidably installed on both sides of the storage bin 12, and the two blocking nets 14 are connected by a set bidirectional drive mechanism.

[0029] A scalding-proof paper bowl is conveyed using the above-mentioned scalding-proof paper bowl production device, including a bowl body 40. The bowl body 40 adopts a double-layer design, consisting of an inner bowl body and an outer bowl body, and the inner surface of the bowl body 40 is coated with a heat-insulating coating.

[0030] Reference Manual Figure 1 and Figure 2It can be seen that the plurality of rubber strips 3 are used to prevent the bowl body 40 from slipping, and the plurality of rubber strips 3 are uniformly pasted on the outer surface of the belt at an inclination of 15°, with a spacing of 100 mm and a strip height of 30 mm. The bowl body 40 moves upward along the movement path below the outer surface of the climbing conveyor 2, so as to ensure sufficient friction when the bowl body 40 is conveyed and avoid the bowl body 40 from slipping. The drying ventilator 4 arranged above the climbing conveyor 2 can dry the bowl body 40.

[0031] The erecting mechanism comprises a fixed seat 11 fixedly arranged above one side in the interior of the storage bin 12, a box body 7 fixedly arranged on the side away from the storage bin 12 of the fixed seat 11, and a lifting cylinder 8 penetratingly installed above in the interior of the box body 7. The overturning piece comprises a mounting block 19 fixedly arranged at the telescopic end of the lifting cylinder 8, and a No. 1 motor 21 installed in the interior of the mounting block 19. The output shaft of the No. 1 motor 21 penetrates and inserts into the interior of the movable frame 13. The tension reset mechanism comprises clamping plates 35 respectively installed at two ends of one side in the interior of the movable frame 13. The clamping plates 35 on the side close to each other are both connected with sliding plates 33 through the arranged positioning springs 36. The two sliding plates 33 are commonly provided with a tension spring 39. The clamping plate 35 is provided with a fixed sleeve 38 at one end in the interior. The sliding plate 33 is provided with a sliding sleeve 34 at one end in the interior. Two groups of fixed sleeves 38 are commonly connected with clamping rods 32 penetratingly. The sliding sleeve 34 is slidingly sleeved on the outside of the clamping rod 32. The elastic rope 37 is connected with the outside of the sliding sleeve 34 at one end.

[0032] The reference drawings are attached to the specification Figure 3 and Figure 4 It can be seen that, under the connection of the fixed seat 11, the box body 7 can be stably installed above in the interior of the storage bin 12. In use, the lifting cylinder 8 drives the mounting block 19 to lift in the interior of the storage bin 12, and the output shaft of the No. 1 motor 21 can synchronously drive the movable frame 13 to overturn.

[0033] The reference drawings are attached to the specification Figure 4 , Figure 5 and Figure 8 It can be seen that the lifting cylinder 8 presses down the movable frame 13, so that the two elastic ropes 37 are embedded into the edge of the uppermost bowl body 40. Correspondingly, the two sliding plates 33 and the sliding sleeve 34 slide along the outside of the clamping rod 32. After the bowl body 40 is clamped, the tension spring 39 generates a rebounding force, so that the two elastic ropes 37 are tightly attached to the outer wall of the bowl body 40. At this time, the lifting cylinder 8 is lifted, and the movable frame 13 lifts the single bowl body 40 to a suitable height. This stage can complete the separate conveying of the single bowl body 40.

[0034] It needs to be specially pointed out that the rigidity of the positioning spring 36 is 15 N / m, the rigidity of the tension spring 39 is 20 N / m, and the elastic rope 37 can adopt a 3 mm nylon elastic rope with a tensile strength ≥ 150 MPa.

[0035] A material guide platform 26 is fixedly installed inside the two groups of box bodies 7 on one side facing the climbing conveyor 2. A support frame 6 is respectively provided on the outside of the two groups of box bodies 7 and below the material guide platform 26. The upper surfaces of the two support frames 6 are correspondingly connected to the support base 23 through the provided telescopic cylinder 24. A vacuum air pump 22 and a No. 2 motor 27 are respectively installed above the two support bases 23. The output end of the No. 2 motor 27 is fixedly connected to a turning cylinder 28. An arc-shaped planing groove 29 is provided inside one side of the turning cylinder 28. A plurality of adsorption holes 30 are provided inside the turning cylinder 28 and located at the arc-shaped planing groove 29. The end of the turning cylinder 28 away from the No. 2 motor 27 is provided with a A negative pressure mechanism is provided, a drying ventilator 4 is mounted above the outside of the climbing conveyor 2, an oblique frame 9 is commonly installed on the outer wall of one side of the two groups of box bodies 7, a pushing cylinder 10 is installed inside the oblique frame 9, and a pushing plate 15 is fixedly installed on the telescopic end of the pushing cylinder 10. A mounting rod 18 is commonly provided on the outside of the two groups of box bodies 7 and located above the guide platform 26. A dynamic capture camera 20 is installed on the top wall of the mounting rod 18. The negative pressure mechanism includes a connecting hard pipe 25 connected to the end installed on the flipping cylinder 28 and away from the No. 2 motor 27. The end of the connecting hard pipe 25 away from the No. 2 motor 27 is connected to the air inlet end of the vacuum air pump 22 through a set of rotating joints 31;

[0036] Reference Manual Figure 5 、 Figure 6 and Figure 7 It can be seen that when the bowl body 40 is lifted to the top of the material guide platform 26, the No. 1 motor 21 drives the movable frame 13 to rotate, and the direction of the bowl body 40 falling later is toward the inside of the material guide platform 26. The pushing cylinder 10 pushes the pushing plate 15 to push the bowl body 40 stuck between the two elastic ropes 37, causing it to fall to the material guide platform 26. The dynamic capture camera 20 monitors the posture of the bowl body 40 in real time. When it is detected that the bowl mouth is facing down, a signal is sent to the industrial PLC controller. The external industrial PLC controller controls the telescopic cylinder 24 to drive the flipping cylinder 28 to rise, and the vacuum air pump 22 generates negative pressure through the connecting hard pipe 25. The adsorption hole 30 adsorbs the outside of the bowl body 40 with the bowl mouth facing down, and then the No. 2 motor 27 drives the flipping cylinder 28 to flip toward the side of the climbing conveyor 2 to complete the posture correction.

[0037] When the turning drum 28 rotates along with the second motor 27 , the corresponding rotating joint 31 adaptively rotates on one side of the connecting hard pipe 25 .

[0038] The bidirectional drive mechanism includes a fixed plate 16 respectively installed in the middle of the bottom of the barrier 14, and a bidirectional telescopic rod 17 is provided between the two sets of fixed plates 16. The external part of the bidirectional telescopic rod 17 is fixedly installed on the bottom of the storage bin 12 through a set sleeve. The bottom of the storage bin 12 is provided with a sliding groove adapted to the sliding of the fixed plate 16;

[0039] Reference Manual Figure 3It can be seen that the bidirectional telescopic rod 17 can drive the blocking net 14 to gather the bowl bodies 40 on both sides of the edge of the storage bin 12 toward the center, thereby transporting the bowl bodies 40 stacked inside the storage bin 12 one by one.

[0040] In summary, in this solution, the elastic rope 37 and the tension reset mechanism can cooperate to achieve flexible grasping of a single bowl, which is suitable for different bowl shapes;

[0041] Intelligent correction: The dynamic capture camera 20 is linked with the turning cylinder 28 to ensure that the bowl mouth is accurately facing upwards;

[0042] Automation integration: Full automation from separation, detection to flipping, improving production efficiency by more than 30%.

[0043] Working principle: The stacked bowl bodies 40 are placed in the storage bin 12, and the two-way blocking nets 14 on both sides can gather the bowl bodies 40 on both sides of the storage bin 12 toward the center through the two-way driving mechanism and the two-way telescopic rod 17 when the bowl is put on;

[0044] The lifting cylinder 8 drives the mounting block 19, the No. 1 motor 21, and the movable frame 13 to press down, so that the two elastic ropes 37 are embedded in the outer edge of the stacked bowl body 40. When the movable frame 13 rises, the elastic rope 37 is acted upon by the tension reset mechanism, and the sliding sleeve 34 slides along the clamping rod 32. The tension spring 39 contracts to generate a rebound force, causing the two elastic ropes 37 to be stuck against the lower edge of the bowl body 40. Then, under the recovery of the lifting cylinder 8, the bowl body 40 is driven to separate from the stack, realizing single bowl separation. When it is immediately lifted to the top of the guide platform 26, the No. 1 motor 21 drives the movable frame 13 to rotate and tilt to one side of the climbing conveyor 2, and the pushing cylinder 10 at the inclined frame 9 pushes the push plate 15 against the side of the bowl body 40. The bowl body 40 is ejected, causing the bowl body 40 to fall to the inclined material guide platform 26, and the dynamic capture camera 20 monitors the posture of the bowl body 40 in real time. When it is detected that the bowl mouth is facing downward, a signal is sent to the external industrial PLC controller. The industrial PLC controller controls the telescopic cylinder 24 to drive the flipping cylinder 28 to rise, and the vacuum air pump 22 generates negative pressure through the connecting hard pipe 25. The adsorption hole 30 adsorbs the outside of the bowl body 40 with the bowl mouth facing downward, and the No. 2 motor 27 drives the flipping cylinder 28 to rotate 180° to complete the posture correction of the bowl mouth upward, and then the bottom of one side of the bowl body 40 is brought into contact with the belt of the climbing conveyor 2, and the bowl body 40 is conveyed upward to complete subsequent coding marking and other tasks.
