Description

Technical Field

[0001] This invention belongs to the field of production and conveying technology, and specifically discloses a device for producing anti-scalding paper bowls and an anti-scalding paper bowl. Background Technology

[0002] Anti-scalding paper bowls are specially designed to effectively reduce the risk of burns when users come into contact with them, and are widely used in the catering industry.

[0003] Increasing the thickness of the paper bowl improves its heat insulation performance. The thicker paper layer slows down heat conduction, providing some protection against scalding. For example, some paper bowls used for holding hot drinks are made with thicker paper, resulting in a more robust overall shape. These bowls have a higher market share and are widely used in the catering industry.

[0004] When producing heat-resistant paper bowls, the bowls need to be printed, stacked, and packaged. The heat-resistant paper bowls produced in the existing workshop are all stacked and collected together. They need to be peeled off one by one during the transportation process, which wastes a lot of time and has low separation efficiency. Some bowls will be stuck with their mouths facing down, requiring additional adjustment processes.

[0005] Therefore, an apparatus for producing heat-resistant paper bowls and a heat-resistant paper bowl are proposed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a device for producing anti-scalding paper bowls, including a frame, an inclined conveyor mounted on the frame, multiple rubber clips on the outer surface of the inclined conveyor belt, a fixed frame on one side of the frame, a storage bin fixedly mounted on the outside of the fixed frame, a mounting mechanism on both sides inside the storage bin, a lifting cylinder on the upper part of each mounting mechanism, a movable frame connected to the telescopic ends of two lifting cylinders by a rotating part, two elastic ropes inside the movable frame, a tension reset mechanism on the outer side of both ends of the two elastic ropes, and a barrier net slidably mounted on both sides inside the storage bin, the two barriers nets being connected by a bidirectional drive mechanism.

[0007] In the above technical solution, the erection mechanism further includes a fixed base fixedly installed above one side of the storage compartment, a box body fixedly installed on the side of the fixed base away from the storage compartment, and a lifting cylinder installed through the upper part of the box body.

[0008] In the above technical solution, furthermore, a guide platform is fixedly installed inside the two sets of boxes facing the inclined conveyor. Support frames are respectively set on the outside of the two sets of boxes and below the guide platforms. Support seats are connected to the upper surfaces of the two support frames through telescopic cylinders. A vacuum pump and a second motor are respectively installed above the two support seats. A turning cylinder is fixedly connected to the output end of the second motor. An arc-shaped groove is opened inside one side of the turning cylinder. Multiple sets of adsorption holes are opened inside the turning cylinder and at the arc-shaped groove. A negative pressure mechanism is set at the end of the turning cylinder away from the second motor. A drying and ventilation fan is installed above the outside of the inclined conveyor. An inclined frame is installed on the outer wall of one side of the two sets of boxes. A pushing cylinder is installed inside the inclined frame. A pushing plate is fixedly installed at the telescopic end of the pushing cylinder. An installation rod is set on the outside of the two sets of boxes and above the guide platform. A dynamic capture camera is installed on the top wall of the installation rod.

[0009] In the above technical solution, the negative pressure mechanism further includes a connecting rigid pipe installed on the flipping cylinder and located away from the No. 2 motor. The end of the connecting rigid pipe away from the No. 2 motor is connected to the air inlet of the vacuum pump through a fitted rotating joint.

[0010] In the above technical solution, the flipping component further includes a mounting block fixedly installed at the telescopic end of the lifting cylinder, and a No. 1 motor is installed inside the mounting block, with the output shaft of the No. 1 motor penetrating and inserting into the interior of the movable frame.

[0011] In the above technical solution, the tension reset mechanism further includes a locking plate installed at both ends of one side inside the movable frame. The sides of the locking plates that are close to each other are connected to a sliding plate by a positioning spring. A tension spring is provided between the two sliding plates. A fixing sleeve is provided inside one end of the locking plate, and a sliding sleeve is provided inside one end of the sliding plate. A locking rod is connected through the two sets of fixing sleeves. The sliding sleeve is slidably sleeved on the outside of the locking rod. One end of the elastic rope is connected to the outside of the sliding sleeve.

[0012] In the above technical solution, the bidirectional drive mechanism further includes fixed plates respectively installed in the middle of the bottom of the barrier net, and a bidirectional telescopic rod is provided between the two sets of fixed plates. The bidirectional telescopic rod is fixedly installed at the bottom of the storage bin by a sleeve. The bottom of the storage bin is provided with a sliding groove adapted to the sliding of the fixed plates.

[0013] A heat-resistant paper bowl is conveyed using the aforementioned heat-resistant paper bowl production device. The bowl includes a bowl body with a double-layer design, consisting of an inner bowl body and an outer bowl body, and the inner surface of the bowl body is coated with a heat-insulating coating.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting up a movable frame inside the storage compartment, with two elastic ropes and a tension reset mechanism installed inside, the movable frame is driven down by a lifting cylinder. The two elastic ropes can be embedded into the edge of the stacked bowls, allowing one set of bowls to be individually clamped and transported separately. This solves the time-consuming problem of traditional manual peeling, and the flexible design of the elastic ropes can be adapted to different bowl shapes.

[0016] 2. By using a flipping cylinder and a dynamic capture camera, the orientation of the bowl is monitored in real time, triggering the flipping operation. An arc-shaped groove and suction holes are opened inside the flipping cylinder. A vacuum pump provides suction force through a negative pressure mechanism, which can flip the bowl with the rim facing down by 180° and transport the rim face to the inclined conveyor, thus facilitating subsequent operations such as inkjet printing.

[0026] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0028] like Figures 1-8 The device shown is for producing anti-scalding paper bowls. It includes a frame 1, an inclined conveyor 2 installed on the top of the frame 1, and multiple rubber clips 3 on the outer surface of the belt of the inclined conveyor 2. A fixed frame 5 is installed on the outer side of one end of the frame 1. A storage bin 12 is fixedly installed on the outer side of the fixed frame 5. A support mechanism is installed on both sides inside the storage bin 12. A lifting cylinder 8 is installed on the top of the support mechanism. The extension and retraction ends of the two lifting cylinders 8 are connected to a movable frame 13 through a flipping part. Two elastic ropes 37 are installed inside the movable frame 13. A tension reset mechanism is installed on the outer side of both ends of the two elastic ropes 37. A barrier net 14 is slidably installed on both sides inside the storage bin 12. The two barrier nets 14 are connected by a bidirectional drive mechanism.

[0029] A heat-resistant paper bowl is conveyed using the aforementioned heat-resistant paper bowl production device. The bowl 40 has a double-layer design, consisting of an inner bowl and an outer bowl, and the inner surface of the bowl 40 is coated with a heat-insulating coating.

[0030] Reference manual attached Figure 1 and Figure 2It is known that multiple rubber clips 3 are used to prevent slipping of the conveyor bowl 40. The multiple rubber clips 3 are evenly pasted on the outer surface of the belt at an angle of 15° with a spacing of 100mm and a clip height of 30mm. The bowl 40 is conveyed in the upward movement path below the outer surface of the inclined conveyor 2, which can ensure sufficient friction when the bowl 40 is conveyed and prevent the bowl 40 from slipping. A drying fan 4 is installed above the inclined conveyor 2 to dry the bowl 40.

[0031] The erection mechanism includes a fixed base 11 fixedly installed on one side of the storage compartment 12. A box 7 is fixedly installed on the side of the fixed base 11 away from the storage compartment 12. A lifting cylinder 8 is installed through the upper part of the box 7. The flipping component includes a mounting block 19 fixedly installed at the telescopic end of the lifting cylinder 8. A motor 21 is installed inside the mounting block 19. The output shaft of the motor 21 is inserted through the interior of the movable frame 13. The tension reset mechanism includes a locking plate 35 installed at both ends of one side of the movable frame 13. The sides of the locking plates 35 that are close to each other are connected to a sliding plate 33 by a positioning spring 36. A tension spring 39 is provided between the two sliding plates 33. A fixing sleeve 38 is provided inside one end of the locking plate 35. A sliding sleeve 34 is provided inside one end of the sliding plate 33. A locking rod 32 is connected through the two sets of fixing sleeves 38. The sliding sleeve 34 is slidably sleeved on the outside of the locking rod 32. One end of the elastic rope 37 is connected to the outside of the sliding sleeve 34.

[0032] Reference manual attached Figure 3 and Figure 4 It can be seen that with the connection of the fixed seat 11, the box 7 can be stably installed above the inside of the storage 12. When in use, the lifting cylinder 8 drives the mounting block 19 to rise and fall above the inside of the storage 12, and the output shaft of the first motor 21 can synchronously drive the movable frame 13 to rotate.

[0033] Reference manual attached Figure 4 , Figure 5 and Figure 8 It can be seen that when the lifting cylinder 8 presses down the movable frame 13, the two elastic ropes 37 are embedded in the edge of the uppermost bowl 40. The corresponding two sliding plates 33 and sliding sleeves 34 slide along the outside of the locking rod 32. After the bowl 40 is locked, the tension spring 39 generates a rebound force, so that the two elastic ropes 37 are tightly attached to the outer wall of the bowl 40. At this time, the lifting cylinder 8 rises, and the movable frame 13 lifts the single bowl 40 to a suitable height. This stage can complete the separation and conveying of the single bowl 40.

[0034] It should be noted that the stiffness of the positioning spring 36 is 15 N / m, the stiffness of the tension spring 39 is 20 N / m, and the elastic cord 37 can be made of 3 mm nylon elastic cord with a tensile strength ≥ 150 MPa.

[0035] Both sets of housings 7 have guide platforms 26 fixedly installed inside on the side facing the inclined conveyor 2. Support frames 6 are respectively installed on the outside of the two sets of housings 7 and below the guide platforms 26. Support seats 23 are connected to the upper surfaces of the two support frames 6 via telescopic cylinders 24. A vacuum pump 22 and a second motor 27 are respectively installed above the two support seats 23. A turning cylinder 28 is fixedly connected to the output end of the second motor 27. An arc-shaped groove 29 is opened inside one side of the turning cylinder 28. Multiple sets of suction holes 30 are opened inside the turning cylinder 28 at the arc-shaped groove 29. The end of the turning cylinder 28 away from the second motor 27 is equipped with... Equipped with a negative pressure mechanism, a drying fan 4 is mounted above the outside of the inclined conveyor 2. An inclined frame 9 is installed on one side of the outer wall of the two sets of boxes 7. A pusher cylinder 10 is installed inside the inclined frame 9. A pusher plate 15 is fixedly installed at the telescopic end of the pusher cylinder 10. An installation rod 18 is set on the outside of the two sets of boxes 7 and above the guide platform 26. A dynamic capture camera 20 is installed on the top wall of the installation rod 18. The negative pressure mechanism includes a connecting hard pipe 25 that is installed on the flipping cylinder 28 and is away from the second motor 27. The end of the connecting hard pipe 25 away from the second motor 27 is connected to the air inlet of the vacuum pump 22 through a set of rotating joints 31.

[0036] Reference manual attached Figure 5 , Figure 6 and Figure 7 As can be seen, when the bowl 40 is raised above the guide platform 26, the first motor 21 drives the movable frame 13 to rotate. The bowl 40 falls towards the inside of the guide platform 26. The pushing cylinder 10 pushes the pushing plate 15 to push the bowl 40, which is stuck between the two elastic ropes 37, so that it falls to the guide platform 26. The dynamic capture camera 20 monitors the posture of the bowl 40 in real time. When it detects that the bowl opening is facing down, it sends a signal to the industrial PLC controller. The external industrial PLC controller controls the telescopic cylinder 24 to drive the flipping cylinder 28 to rise. The vacuum pump 22 generates negative pressure through the connecting rigid pipe 25. The suction hole 30 suctions the outside of the bowl 40 with the bowl opening facing down. Then the second motor 27 drives the flipping cylinder 28 to flip towards one side of the inclined conveyor 2, completing the posture correction.

[0037] When the turning cylinder 28 rotates with the second motor 27, the corresponding rotating joint 31 adapts to rotate on the side of the connecting rigid pipe 25.

[0038] The bidirectional drive mechanism includes fixed plates 16 installed in the middle of the bottom of the barrier net 14. A bidirectional telescopic rod 17 is provided between the two sets of fixed plates 16. The bidirectional telescopic rod 17 is fixedly installed at the bottom of the storage bin 12 by a sleeve. The bottom of the storage bin 12 is provided with a sliding groove adapted to the sliding of the fixed plates 16.

[0039] Reference manual attached Figure 3It can be seen that the bidirectional telescopic rod 17 can drive the barrier net 14 to gather the bowls 40 on both sides of the inside of the storage bin 12 toward the center, thereby conveying the bowls 40 stacked inside the storage bin 12 one by one.

[0040] In summary, this solution can achieve flexible gripping of a single bowl by working together with the elastic cord 37 and the tension reset mechanism, adapting to different bowl shapes;

[0041] Intelligent correction: The dynamic capture camera 20 works in conjunction with the flipping tube 28 to ensure that the bowl is accurately facing upwards;

[0042] Automation integration: The entire process from separation and testing to flipping is automated, improving production efficiency by more than 30%.

[0043] Working principle: The stacked bowls 40 are placed in the storage compartment 12. The two side nets 14 can gather the bowls 40 on both sides of the storage compartment 12 towards the center when the bowls are placed in the compartment through the two-way drive mechanism and the two-way telescopic rod 17.

[0044] The lifting cylinder 8 drives the mounting block 19, the first motor 21, and the movable frame 13 to press down, causing the two elastic ropes 37 to embed into the outer edge of the stacked bowls 40. When the movable frame 13 rises, the elastic ropes 37 are subjected to the tension reset mechanism, the sliding sleeve 34 slides along the locking rod 32, and the tension spring 39 contracts to generate a rebound force, causing the two elastic ropes 37 to be locked against the lower edge of the bowl 40. Then, under the lifting cylinder 8's return, the bowl 40 is driven to detach from the stack, realizing single bowl separation. When it is lifted above the guide platform 26, the first motor 21 drives the movable frame 13 to rotate and tilt towards one side of the inclined conveyor 2. The pushing cylinder 10 at the inclined frame 9 pushes the push plate 15 against one side of the bowl 40. Bowl 40 is ejected and falls onto the inclined guide platform 26. The dynamic capture camera 20 monitors the posture of bowl 40 in real time. When it detects that the bowl opening is facing down, it sends a signal to the external industrial PLC controller. The industrial PLC controller controls the telescopic cylinder 24 to drive the flipping cylinder 28 to rise. The vacuum pump 22 generates negative pressure through the connecting rigid pipe 25. The suction hole 30 suctions the outside of the bowl 40 with the bowl opening facing down. The second motor 27 drives the flipping cylinder 28 to rotate 180° to complete the posture correction of the bowl opening facing up. Then, one bottom side of the bowl 40 contacts the belt of the inclined conveyor 2, and the bowl 40 is conveyed upward to complete subsequent work such as inkjet marking.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely extensions of the present invention. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
