Description

Technical Field

[0001] This application relates to the technical field of paper cup production and transportation, and particularly to a three-dimensional flocked paper cup production device and process. Background Art

[0002] A three-dimensional flocked paper cup is a paper cup that uses an electrostatic adsorption process to vertically implant short fiber fluff into an adhesive layer through a high-voltage electrostatic field. The paper cup forms a three-dimensional tactile surface, with anti-slip and heat insulation effects.

[0003] After the production of three-dimensional flocked paper cups is completed, they need to be transported and palletized. For example, the patent application with the publication number CN218344548U provides a batch feeding device for paper cup production. An electric telescopic rod drives a pressing plate to apply a controllable pressure to the paper cups in the collection cylinder, so that the stacking depth between the paper cups increases evenly, avoiding the problem of loose misalignment caused by traditional free stacking. At the same time, the physical limit principle is used to constrain the conveying path of the paper cups, so that the paper cups maintain a longitudinally aligned state when moving on the conveyor belt.

[0004] The three-dimensional flocked paper cup is a type of paper cup, so the above technology can also be used for the feeding and palletizing of three-dimensional flocked paper cups. However, there are still the following deficiencies: due to the poor stability of electrostatic adsorption and physical friction and other factors, the adhesion of the fluff on the surface of the three-dimensional flocked paper cup decreases, resulting in easy shedding of the fluff. The shed fluff is likely to fall inside the three-dimensional flocked paper cup during the floating process in the environment, causing pollution inside the three-dimensional flocked paper cup and affecting the quality of the three-dimensional flocked paper cup.

[0005] Based on this, there is still room for improvement in the way of three-dimensional flocked paper cups during feeding and transportation. Summary of the Invention

The threaded rod is in transmission connection with the rotating shaft through a belt drive method.

[0018] Preferably, the dust suction pipe is a bent structure that matches the inner wall of the paper cup. A communication groove is opened inside the rotating shaft and is connected to the inside of the dust suction pipe. Multiple transition pipes that are connected to the communication groove and the dust suction pipe are also arranged between the rotating shaft and the dust suction pipe. A blower plate is installed on the rotating shaft.

[0019] Preferably, the cleaning part includes: The cleaning roller is inclined. Connecting protrusions are installed on both the rotating shaft and the dust suction pipe, and the cleaning roller is rotatably installed on the connecting protrusions through bearings. And an electrostatic wire is installed on the cleaning roller.

[0020] The second gear, one end of the cleaning roller close to the lifting plate penetrates through the corresponding connecting protrusion, and the second gear is installed on the shaft head of the cleaning roller close to the lifting plate.

[0022] Preferably, a reversing frame is installed on the support frame corresponding to any conveying roller. A reversing roller is installed between the reversing frames through bearings. A plurality of mounting blocks are uniformly arranged along the circumferential direction at the center position of the circumferential surface of the reversing roller.

During the rotation of the rotating shaft driving the cleaning part, the rotation direction is opposite to that of the paper cup.

[0030] 2. In the limiting part of the present invention, when the first rack plate drives the rubber plates to move towards each other, a dynamic limiting structure is formed through the elastic contact surface. When effectively restraining the circumferential displacement of the paper cup during the cleaning process while radially squeezing and restraining the bottom of the paper cup; at the same time, the static friction force generated between the rubber plate and the surface of the paper cup can be converted into a tangential driving force to drive the paper cup to generate a rotational motion state around its axis. This composite motion mechanism enables the paper cup to not only maintain the axial positioning stability, but also form a differential motion trajectory with the cleaning roller through the rotational motion, thereby generating a bidirectional shear force field and significantly improving the cleaning efficiency.

[0031] 3. The reversing roller and the vacuum suction cup designed in the present invention cooperate with each other to achieve precise control of the posture of the paper cup. When the reversing roller rotates to a preset angle, the vacuum suction cups distributed on its surface will firmly adsorb the outer wall of the paper cup, driving the cup body to complete a 180-degree azimuth flip, so that the cup mouth forms a working posture with the opening facing vertically downward. During this process, the fluff attached to the inner wall of the paper cup generates a directional displacement under the action of gravitational acceleration, and is automatically peeled off from the paper cup through the gravity sedimentation effect.

Detailed Description of the Embodiments

[0040] The following further describes the present application in detail Figures 1 to 7 with reference to the accompanying drawings.

[0041] The embodiments of the present application disclose a three-dimensional flocked paper cup production device and process, which perform multiple cleaning processes on the fluff inside the paper cup through methods such as air flow disturbance, adhesion capture, negative pressure cleaning, and paper cup inversion.

[0042] Referring to Figure 1 and Figure 2 , a three-dimensional flocked paper cup production device includes two symmetrically arranged conveying rollers 1. A conveyor belt 2 is commonly installed between the conveying rollers 1. A plurality of through-limiting grooves 21 are uniformly formed in the conveyor belt 2 along its length direction. Above the conveyor belt 2, a cleaning mechanism 3 for removing the fluff on the inner wall of the paper cup 100 is provided. The cleaning mechanism 3 includes: A lifting plate 31 is arranged above the conveyor belt 2 and reciprocates up and down along the height direction of the paper cup 100.

[0043] A rotating shaft 32 is rotatably installed on the lifting plate 31 through a bearing.

[0044] A dust suction pipe 33 is installed on the rotating shaft 32 to adsorb and collect the fluff on the inner wall of the paper cup 100.

[0045] A limiting part 34 is arranged between the two conveying rollers 1 to limit the bottom of the paper cup 100.

[0046] A cleaning part 35 is arranged on the rotating shaft 32 to separate the fluff from the inner wall of the paper cup 100.

[0047] Wherein the arrow direction in the figure is the conveying direction of the paper cup 100. The cleaning part 35 can separate the fluff from the inner wall of the paper cup 100, and then collect the fluff through the dust suction pipe 33. During the rotation of the rotating shaft 32 driving the cleaning part 35, the rotation direction is opposite to that of the paper cup 100. Therefore, a relative movement is formed between the contact surface of the cleaning part 35 and the inner wall of the paper cup 100, thereby increasing the friction force between the contact surface of the cleaning roller 351 and the inner wall of the paper cup 100 and improving the fluff stripping efficiency.

[0048] Referring to Figure 1 , both ends of the conveying roller 1 are provided with support frames 11, and both ends of the conveying roller 1 are installed on the support frames 11 through bearings. Guide rods 12 are symmetrically arranged above the conveyor belt 2 along its width direction, and the guide rods 12 are installed on the top of the corresponding support frames 11 through guide frames 13.

[0049] During specific operation, an external driving force (such as a motor, not shown in the figure) drives the conveying roller 1 to rotate. During the rotation of the conveying roller 1, the conveyor belt 2 is driven to move. At this time, the paper cups 100 are placed one by one inside the limiting grooves 21. During the movement of the conveyor belt 2, it cooperates with the limiting grooves 21 to convey the paper cups 100 along the advancing direction of the conveyor belt 2. During the conveying process, the two guiding rods 12 cooperate with each other to limit the paper cups 100, preventing the paper cups 100 from shifting and affecting the subsequent alignment effect between the paper cups 100 and the rotating shaft 32.

[0050] Referring to Figure 1 and Figure 4 , in order to prevent the paper cups 100 from shaking during the cleaning process, the limiting part 34 provided by the present invention can limit the paper cups 100 during the cleaning process. Specifically, the limiting part 34 includes: Fixed connecting frames 341, there are two of them, symmetrically distributed along the length direction of the conveyor belt 2, and are installed between the corresponding support frames 11 on both sides. A fixed frame 342 is jointly installed between the two fixed connecting frames 341.

[0051] Rotating shaft 343, installed on the fixed frame 342 through bearings and coaxial with the rotating shaft 32. A first gear 344 is installed on the rotating shaft 343.

[0052] Support rods 345, there are two of them, symmetrically arranged along the center of the rotating shaft 343, and are installed on the fixed frame 342.

[0053] First rack plates 346, there are two of them, symmetrically arranged along the center of the rotating shaft 343, and are slidably arranged on the tops of the support rods 345 and meshed with the first gear 344.

[0054] Rubber plates 347, there are two of them and are respectively installed on the corresponding first rack plates 346.

[0055] Among them, the conveying roller 1 rotates step by step, that is, every time the conveying roller 1 rotates a certain angle, there is always a through groove on the conveyor belt 2 coaxial with the rotating shaft 32. Furthermore, at any moment, the paper cup 100 moved under the lifting plate 31 is coaxial with the rotating shaft 32 and the rotating shaft 343, so as to ensure that the cleaning part 35 can smoothly enter the inside of the paper cup 100. During specific operation, when the paper cup 100 moves to the bottom of the lifting plate 31, at this time, an external drive (such as a motor, not shown in the figure) drives the rotating shaft 343 to rotate. During the rotation of the rotating shaft 343, the first rack plates 346 move towards each other. At this time, the first rack plates 346 slide on the support rods 345, and the rubber plates 347 are synchronously driven to move during the movement of the first rack plates 346.

[0056] Furthermore, when the first rack plate 346 drives the rubber plate 347 to move towards each other, a dynamic limiting structure is formed through the elastic contact surface. When radially squeezing and restraining the bottom of the paper cup 100, the circumferential displacement of the paper cup 100 during the cleaning process can be effectively inhibited. At the same time, the static friction force generated between the rubber plate 347 and the surface of the paper cup 100 can be converted into a tangential driving force to drive the paper cup 100 to rotate around its axis. This composite motion mechanism enables the paper cup 100 to maintain axial positioning stability and form a differential motion trajectory with the cleaning part 35 through the rotational motion, thereby generating a bidirectional shear force field and significantly improving the cleaning efficiency.

[0057] Therefore, the rotation direction of the rotating shaft 32 is opposite to that of the paper cup 100. And at the initial stage, the distance between the two first rack plates 346 in the width direction of the conveyor belt 2 is much larger than the diameter of the paper cup 100 to ensure that the paper cup 100 will not collide with the first rack plates 346 when passing over the two first rack plates 346.

[0058] Refer to Figure 4 , an extension plate 348 is installed on the fixing frame 342, a vertical rod 349 is installed on the extension plate 348, and the end of the vertical rod 349 away from the extension plate 348 penetrates and is slidably arranged on the lifting plate 31. A threaded rod 340 is also installed on the extension plate 348 through a bearing, and the threaded rod 340 is in transmission connection with the lifting plate 31 through a threaded connection method. The threaded rod 340 and the rotating shaft 343 are in transmission connection through a belt drive method.

[0059] During the rotation of the rotating shaft 343, the threaded rod 340 is driven to rotate through the belt drive method. During the rotation of the threaded rod 340, the lifting plate 31 is driven to move downward through the threaded connection method until the lifting plate 31 moves above the paper cup 100. The vertical rod 349 can limit the lifting plate 31 to prevent the lifting plate 31 from rotating synchronously with the threaded rod 340.

[0060] Refer to Figure 2 , the dust suction pipe 33 is a bent structure that matches the inner wall of the paper cup 100. A communication groove that is connected to the inside of the dust suction pipe 33 is opened inside the rotating shaft 32. Multiple transition pipes that are connected to the communication groove and the dust suction pipe 33 are also arranged between the rotating shaft 32 and the dust suction pipe 33. A blower plate 321 is installed on the rotating shaft 32.

[0061] Among them, the air blowing plate 321 is coated with glue, and the dust suction port of the existing vacuum cleaner (not shown in the figure) is connected to the top of the rotating shaft 32. At this time, the communication groove is connected to the dust suction port of the vacuum cleaner. Specifically, during operation, when the lifting plate 31 moves downward, it drives the rotating shaft 32 to move into the paper cup 100. At this time, the rotating shaft 32 is driven to rotate by an external driving force. During the rotation of the rotating shaft 32, the air blowing plate 321 rotates circumferentially. During the circumferential rotation of the air blowing plate 321, a turbulence effect is generated, forming a dynamic airflow field inside the paper cup 100. As a result, some of the fluff on the inner wall of the paper cup 100 that is easier to clean detaches from the cup wall and is in a suspended state. The glue on the air blowing plate 321 can adhere to the fluff diffused inside the paper cup 100. Therefore, the air blowing plate 321 and the glue cooperate with each other to adhere to some of the fluff that is easier to clean, achieving secondary trapping of the remaining attached fluff.

[0062] The transition pipe can assist the rotating shaft 32 in transporting the fluff inside the dust suction pipe 33.

[0063] During this process, the rotating shaft 32 synchronously drives the dust suction pipe 33 to rotate to adsorb the fluff adhered to the inner wall of the paper cup 100 and the fluff diffused inside the paper cup 100. Thus, multiple collections of the fluff inside the paper cup 100 are achieved through the methods of air flow disturbance, adhesion trapping, and negative pressure cleaning.

[0064] Refer to Figure 2 and Figure 3 , in order to remove some of the fluff on the inner wall of the paper cup 100 that is more difficult to remove, the cleaning part 35 provided by the present invention can clean the fluff adhered to the inner wall of the paper cup 100. Specifically, the cleaning part 35 includes: A cleaning roller 351, which is inclined. Connecting protrusions are installed on both the rotating shaft 32 and the dust suction pipe 33, and the cleaning roller 351 is rotatably installed on the connecting protrusion through a bearing, and an electrostatic wire 352 is installed on the cleaning roller 351.

[0065] A second gear 353. One end of the cleaning roller 351 close to the lifting plate 31 penetrates through the corresponding connecting protrusion, and the second gear 353 is installed on the shaft head of the cleaning roller 351 close to the lifting plate 31.

[0066] A second rack plate 354, which is arranged in an annular structure and is installed on the lifting plate 31 through a connecting block and meshes with the second gear 353.

[0067] Specifically, during operation, when the rotating shaft 32 rotates, it drives the cleaning roller 351 to rotate circumferentially around the rotating shaft 32 synchronously. At this time, the rotation direction of the cleaning roller 351 is opposite to that of the paper cup 100. As a result, a relative movement is formed between the contact surface of the cleaning roller 351 and the inner wall of the paper cup 100, thereby increasing the friction force of the contact surface between the cleaning roller 351 and the inner wall of the paper cup 100 and improving the fluff stripping efficiency.

[0068] In addition, during the circumferential rotation of the cleaning roller 351, the gear 2 353 and the rack plate 2 354 cooperate with each other to rotate synchronously, and thus the cleaning roller 351 also provides a tangential force to the inner wall of the paper cup 100 during the circumferential rotation around the rotating shaft 32, so that the stubborn fluff attached to the inner wall of the paper cup 100 can be peeled off smoothly.

[0069] The static conductor 352 can discharge the static electricity on the cleaning roller 351 to prevent the fluff from adhering to the cleaning roller 351 due to static electricity.

[0070] In addition, the paper cup 100 and the cleaning roller 351 rotate in opposite directions, thereby preventing the cleaning roller 351 from driving the paper cup 100 to rotate synchronously.

[0071] Reference Figure 5 as well as Figure 6 A reversing frame 111 is installed on the supporting frame 11 corresponding to any conveying roller 1 (since the forward direction of the conveyor belt 2 is specified, the supporting frame 11 at this location is also the supporting frame 11 at the unloading location of the conveyor belt 2), and a reversing roller 112 is installed between the reversing frames 111 through bearings. A plurality of mounting blocks 113 are evenly arranged along the circumference of the reversing roller 112 at the center position of the circumferential surface, and a vacuum suction cup 114 is installed on the mounting block 113.

[0072] The height of the guide frame 13 close to the reversing frame 111 is greater than the height of the guide frame 13 far from the reversing frame 111 , and a guide section is provided at one end of the guide rod 12 close to the reversing frame 111 .

[0073] At the end of the conveyor belt 2, the paper cup 100 is flexibly disengaged from the guide section of the guide rod 12: when it reaches the critical position of the guide section, the special contour surface of the guide rod 12 generates a vertical component through the contact force vector decomposition, so that the paper cup 100 is smoothly lifted along the predetermined trajectory to escape from the limit constraint. Through the trajectory phase synchronization compensation mechanism, the container separation is completed before the limit groove 21 of the conveyor belt 2 is about to enter the corner area of ​​the conveyor roller 1. The contact surface friction coefficient gradient transition and kinetic energy slow release principle are used to effectively eliminate the impact load caused by rigid jamming, ensuring that the paper cup 100 is always within the elastic deformation safety threshold range during the disengagement process, avoiding damage to the paper cup 100.

[0074] A connecting rod 121 is provided at one end of the guide rod 12 close to the reversing frame 111 , and an elastic telescopic rod 122 is provided on the connecting rod 121 . A guide connecting rod 123 coaxial with the guide rod 12 is installed at the telescopic end of the elastic telescopic rod 122 .

[0075] When the paper cup 100 moves to the guiding link 123 through the guiding rod 12, the vacuum suction cup 114 adsorbs the bottom of the paper cup 100 at this time. At this time, the paper cup 100 drives the guiding link 123 to move downward by a certain displacement, and the elastic telescopic rod 122 is compressed. After the vacuum suction cup 114 finishes adsorption, an external drive motor (not shown in the figure) drives the reversing roller 112 to rotate. During the rotation of the reversing roller 112, the mounting block 113 and the corresponding vacuum suction cup 114 cooperate with each other to drive the paper cup 100 to flip 180 degrees. That is, the reversing roller 112 and the vacuum suction cup 114 cooperate with each other to achieve precise control of the posture of the paper cup 100. When the reversing roller 112 rotates to a preset angle, the vacuum suction cups 114 distributed on its surface will firmly adsorb the outer wall of the paper cup 100, driving the cup body to complete a 180-degree azimuth flip, so that the cup mouth forms a working posture with the opening facing vertically downward. During this process, the fluff attached to the inner wall of the paper cup 100 generates a directional displacement under the action of gravitational acceleration, and is automatically peeled off from the paper cup 100 through the gravity sedimentation effect.

[0076] It should be noted that due to the certain height difference between the cup wall and the bottom of the paper cup 100, the distance from the vacuum suction cup 114 to the bottom of the paper cup 100 should be greater than this height difference to avoid the paper cup 100 from colliding with the vacuum suction cup 114 when the guiding rod 12 moves towards the guiding link 123. The elastic telescopic rod 122 and the guiding link 123 cooperate with each other to compensate for this height difference, ensuring that the vacuum suction cup 114 can adsorb the bottom of the paper cup 100 while avoiding the possibility of the paper cup 100 colliding with the vacuum suction cup 114 during the movement.

[0077] That is, the vacuum suction cup 114 and the liftable guiding link 123 cooperate with each other to adopt an anti-collision strategy combining three-dimensional space avoidance and dynamic compensation. Through the cooperative compensation structure composed of the elastic telescopic rod 122 and the guiding link 123, the vertical displacement of the paper cup 100 is dynamically adjusted in real time during the adsorption operation. While ensuring effective adsorption of the bottom of the paper cup 100, it avoids the collision between the paper cup 100 and the vacuum suction cup 114, and realizes the self-consistent control of contact handling and non-interference movement.

[0078] In addition, for each paper cup 100 conveyed to the right, there is always a corresponding vacuum suction cup 114 corresponding to it.

[0079] Furthermore, finally, the paper cup 100 after the reversal is collected and processed.

[0080] Finally, referring to Figure 7 , the present invention also provides a three-dimensional flocked paper cup production process, and its production process includes the following steps: S1: Placement process. The conveyor roller 1 is driven to rotate by an external driving force (such as a motor, not shown in the figure). During the rotation of the conveyor roller 1, the conveyor belt 2 is driven to move. At this time, the paper cups 100 are placed one by one inside the limit slots 21. During the movement of the conveyor belt 2, it cooperates with the limit slots 21 to convey the paper cups 100 along the advancing direction of the conveyor belt 2.

[0081] S2: Limiting process. When the paper cup 100 moves to the bottom of the lifting plate 31, it drives the rotating shaft 343 to rotate at this time. During the rotation of the rotating shaft 343, the first rack plate 346 moves towards each other. At this time, the first rack plate 346 slides on the support rod 345. During the movement of the first rack plate 346, the rubber plate 347 is synchronously driven to move. Furthermore, when the first rack plate 346 drives the rubber plate 347 to move towards each other, a dynamic limiting structure is formed through the elastic contact surface, thereby realizing the radial extrusion constraint on the bottom of the paper cup 100.

[0082] S3: Cleaning process. During the rotation of the rotating shaft 32, the air blowing plate 321 rotates circumferentially. During the circumferential rotation of the air blowing plate 321, a turbulence effect is generated, forming a dynamic airflow field inside the paper cup 100. As a result, some of the fluff that is relatively easy to clean on the inner wall of the paper cup 100 detaches from the cup wall and is in a suspended state, and the glue on the air blowing plate 321 can adhere to the fluff diffused inside the paper cup 100; the rotating shaft 32 synchronously drives the dust suction pipe 33 to rotate to adsorb the fluff adhered to the inner wall of the paper cup 100 and the fluff diffused inside the paper cup 100.

[0083] S4: Collection process. The cleaned paper cups 100 are collected.

[0084] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
