Description

Technical Field

[0001] This utility model relates to the field of packaging paper roll packaging machines, specifically an automated unloading and conveying device for printed packaging paper. Background Technology

[0002] In the field of roll packaging machines, V-type chain conveyors and stop distributors are the core equipment combination in automated packaging lines. The two work together to significantly improve the efficiency of paper roll conveying and the continuity of the packaging process. The V-type chain is driven by a high-strength forged chain. The chain passes around the drive sprocket and tension wheel to form a closed loop, ensuring the stable operation of the conveying line. The stop distributor detects the output rhythm of the rewinder through sensors or encoders and releases the paper roll to the V-type chain conveyor at preset intervals.

[0003] In the traditional unloading and transportation of roll-shaped packaging paper, V-type chain conveyors and stop distributors are used to distribute and transport the packaging paper. However, in actual use, there is a problem: if several packages of paper are placed on one side of the stop distributor, most traditional stop distributors are electrically raised ramp structures. When the stop distributor is released, it fails to effectively limit the subsequent packages of paper, which may cause them to roll together, resulting in unreasonable packaging distribution and reducing the ease of use of the conveying device. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an automated unloading and conveying device for printed packaging paper, so as to solve the technical problem that when multiple packaging papers are placed on one side, it is difficult to effectively limit the subsequent paper rolls after the lock is released, which may cause the paper rolls to roll together and cause unreasonable distribution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automated unloading and conveying device for printed packaging paper, including a support platform, a flipping mechanism, a chain conveyor, and packaging paper rolls. The flipping mechanism includes a first mounting cavity, and a flip plate is rotatably mounted inside the first mounting cavity. The top surface of the flip plate has a curved structure, and one side of the flip plate forms a limiting surface to block adjacent packaging paper rolls. A driving mechanism is mounted on one side of the bottom surface of the flip plate and the inside of the first mounting cavity.

[0006] By adopting the above technical solution, the entire process of packaging paper roll from unloading to conveying is automated. The flip plate in the flipping mechanism adopts a curved top surface, which can perfectly fit the shape of the packaging paper roll, effectively reduce the frictional resistance of the paper roll during the flipping process, and ensure the smooth transition of the paper roll.

[0007] Furthermore, the driving mechanism includes a plurality of first hydraulic push rods, the two ends of which are rotatably mounted to the inner wall of the first mounting cavity and the bottom surface of the flap.

[0008] By adopting the above technical solution, the first hydraulic push rod, as a power source, has the advantages of fast response speed, large output force, and smooth operation. The two ends of the first hydraulic push rod are respectively rotatably installed with the inner wall of the first mounting cavity and the bottom surface of the flap, making the push rod more flexible when pushing the flap to rotate, reducing mechanical wear and energy loss.

[0009] Furthermore, a ramp is laid on one side of the support platform, and the height of the ramp gradually decreases towards the tilting mechanism.

[0010] By adopting the above technical solution, the packaging paper roll can slide naturally towards the turning mechanism by gravity, reducing the need for manual intervention and improving the automation level of the unloading process.

[0011] Furthermore, the limiting surface has an arc structure and abuts against the adjacent packaging paper roll.

[0012] By adopting the above technical solution, it can perfectly fit the outer surface of the adjacent packaging paper roll to form an effective barrier. This not only increases the contact area between the limiting surface and the paper roll and improves the stability of the barrier, but also, in other embodiments, a rotating roller can be installed on the surface of the limiting surface to reduce the damage to the paper roll surface caused by friction.

[0013] Furthermore, several limiting rollers are rotatably installed on the other side of the flip plate, and are arranged linearly at equal intervals.

[0014] By adopting the above technical solution, stable support and guidance can be provided during the paper roll rolling process. The rotation of the limit roller can reduce the frictional resistance between the paper roll and the flip plate, so that the paper roll can roll more smoothly to the chain plate conveyor.

[0015] Furthermore, a limiting mechanism is installed on one side of the chain conveyor. The limiting mechanism includes a second mounting cavity, and a limiting plate is slidably installed inside the second mounting cavity to limit the rolling position of the packaging paper roll. Several second hydraulic push rods are rotatably installed between the limiting plate and the second mounting cavity.

[0016] By adopting the above technical solution, the limiting mechanism can dynamically adjust the rolling position of the paper roll through the limiting plate slidably installed inside the second mounting cavity, ensuring that the paper roll always stays on the correct track during the conveying process. This effectively prevents the paper roll from jamming or falling due to deviation, and improves the continuity and stability of the conveying.

[0017] Furthermore, a detection mechanism is provided at the starting end of the chain conveyor, the detection mechanism including a mounting plate, on which a distance measuring sensor is mounted.

[0018] By adopting the above technical solution, the testing agency can monitor the paper roll's position in real time, providing accurate trigger signals to the flipping mechanism. This ensures that the flipping and conveying operation is only performed after the paper roll is fully in place, avoiding flipping failures or conveying malfunctions caused by the paper roll not being in place.

[0019] In summary, the present invention has the following main advantages:

[0020] This utility model uses a limiting mechanism where a first hydraulic push rod drives a flap to rotate. This action directly achieves precise control over the packaging paper roll. The rotation of the flap allows the limiting surface to accurately block subsequent paper rolls, preventing multiple rolls from entering the chain conveyor at the same time. This ensures that only a single paper roll is released each time. This single-distribution operation significantly improves the accuracy and convenience of paper roll distribution and reduces the need for manual intervention. This not only ensures that a single paper roll can be stably released to the chain conveyor, but also improves the efficiency and stability of paper roll conveying, further enhancing the reliability and practicality of the entire unloading and conveying device.

[0021] This invention utilizes a detection mechanism. The ranging sensor mounted on the mounting plate of the detection mechanism has high precision and high sensitivity, enabling it to accurately identify the position and status of the paper roll. This provides reliable data support for the automated control of the equipment, allowing the entire unloading and conveying device to operate more intelligently and efficiently. By acquiring the position information of the paper roll in real time, the equipment can automatically adjust the timing of flipping and conveying, ensuring that each paper roll is properly handled, further improving the convenience of allocation and work efficiency.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0028] Automated unloading and conveying devices for printed packaging paper, such as Figure 1-4 As shown, the device includes a support platform 1, a tilting mechanism 2, a chain conveyor 3, and a packaging paper roll 6. The tilting mechanism 2 includes a first mounting cavity 201, on which a flap 202 is rotatably mounted. The top surface of the flap 202 has a curved structure, and one side of the flap 202 forms a limiting surface 204 to block adjacent packaging paper rolls 6. A drive mechanism is installed on one side of the bottom surface of the flap 202 and the inside of the first mounting cavity 201, realizing the full automation of the packaging paper roll 6 from unloading to conveying. The flip plate 202 in the turning mechanism 2 adopts a curved top surface, which can perfectly fit the shape of the packaging paper roll 6, effectively reducing the frictional resistance of the paper roll during the turning process and ensuring a smooth transition of the paper roll. At the same time, the limiting surface 204 on one side of the flip plate 202 can accurately block adjacent paper rolls, avoiding the distribution chaos caused by multiple rolls of paper rolling at the same time, significantly improving unloading efficiency and accuracy. In addition, the installation of the drive mechanism provides power support for the rotation of the flip plate 202, making the entire turning process more controllable and stable.

[0029] See Figure 3 , Figure 4 The driving mechanism includes several first hydraulic push rods 205. The two ends of the first hydraulic push rods 205 are rotatably mounted to the inner wall of the first mounting cavity 201 and the bottom surface of the flip plate 202. The first hydraulic push rods 205 serve as a power source and have the advantages of fast response speed, large output force, and smooth operation. The two ends of the first hydraulic push rods 205 are rotatably mounted to the inner wall of the first mounting cavity 201 and the bottom surface of the flip plate 202, respectively, which makes the push rods more flexible when pushing the flip plate 202 to rotate, reducing mechanical wear and energy loss. At the same time, the precise control of the hydraulic push rods can ensure that the flip plate 202 rotates to the required angle at the appropriate time, thereby achieving precise positioning and release of the packaging paper roll 6.

[0030] See Figure 3 A ramp is laid on one side of the support platform 1, and the height of the ramp gradually decreases towards the flipping mechanism 2, so that the packaging paper roll 6 can slide naturally towards the flipping mechanism 2 by gravity, reducing the need for manual intervention and improving the automation of the unloading process. At the same time, the setting of the ramp gradually decreasing towards the flipping mechanism 2 can ensure that the paper roll maintains a stable posture during the sliding process, avoiding the paper roll rolling or jamming caused by sudden changes in height.

[0031] See Figure 3 , Figure 4 The limiting surface 204 has an arc structure and abuts against the adjacent packaging paper roll 6, which can perfectly fit the outer surface of the adjacent packaging paper roll 6 to form an effective barrier. This not only increases the contact area between the limiting surface 204 and the paper roll and improves the stability of the barrier, but also allows for the installation of a rotating roller on the surface of the limiting surface 204 in other embodiments. This reduces the damage to the paper roll surface caused by friction. At the same time, the arc structure can better adapt to the slight deformation of the paper roll during the rolling process, ensuring that the limiting surface 204 always maintains close contact with the paper roll, thereby achieving precise positioning and barrier of the paper roll.

[0032] See Figure 1 , Figure 2 , Figure 4 On the other side of the flip plate 202, several limiting rollers 203 are rotatably installed and arranged linearly at equal intervals. They can provide stable support and guidance during the rolling of the paper roll. The rotation of the limiting rollers 203 can reduce the frictional resistance between the paper roll and the flip plate 202, so that the paper roll can roll more smoothly to the chain conveyor 3. At the same time, the linearly arranged limiting rollers 203 can ensure that the paper roll maintains a stable posture during the rolling process, avoiding paper roll deviation or shaking caused by uneven support.

[0033] See Figure 1 , Figure 2 , Figure 3 A limiting mechanism 4 is installed on one side of the chain conveyor 3. The limiting mechanism 4 includes a second mounting cavity 401. A limiting plate 402 is slidably installed inside the second mounting cavity 401 to limit the rolling position of the packaging paper roll 6. Several second hydraulic push rods 403 are rotatably installed between the limiting plate 402 and the second mounting cavity 401. The limiting mechanism 4 can dynamically adjust the rolling position of the paper roll through the limiting plate 402 slidably installed inside the second mounting cavity 401, ensuring that the paper roll always stays on the correct track during the conveying process. This can effectively prevent the paper roll from jamming or falling due to deviation, and improve the continuity and stability of the conveying. At the same time, the several second hydraulic push rods 403 rotatably installed between the limiting plate 402 and the second mounting cavity 401 can accurately control the position of the limiting plate 402 according to the actual position of the paper roll and the conveying requirements, thereby achieving precise control of the paper roll conveying process. Example 2:

[0034] See Figure 1 , Figure 2 , Figure 3The starting end of the chain conveyor 3 is equipped with a detection mechanism 5, which includes a mounting plate 501 and a distance sensor 502. The detection mechanism 5 can monitor the paper roll's position in real time and provide an accurate trigger signal for the flipping mechanism 2. This ensures that the flipping and conveying operation is only performed after the paper roll is fully in place, avoiding flipping failure or conveying malfunction due to the paper roll not being in place. At the same time, the distance sensor 502 installed on the mounting plate 501 of the detection mechanism 5 has high precision and high sensitivity, and can accurately identify the position and status of the paper roll, providing reliable data support for the automated control of the equipment. This not only improves the accuracy and reliability of the unloading and conveying process, but also reduces equipment damage and safety hazards caused by human error.

[0035] The implementation principle of this embodiment is as follows: The packaging paper roll 6 is first placed on the inclined platform on one side of the support platform 1 and slides along the inclined platform to the flipping mechanism 2. The flipping plate 202 in the flipping mechanism 2 is installed in the first mounting cavity 201. Its top curved structure fits against the packaging paper roll 6 and restricts the current position of the packaging paper roll 6 to prevent it from rolling forward. When the distance sensor 502 in the detection mechanism 5 detects that the previous paper roll has been transported a certain distance by the chain conveyor 3, the first hydraulic push rod 205 pushes the flipping plate 202 to rotate. At the same time, the limiting surface 204 blocks the subsequent paper roll. Meanwhile, the limiting roller 203 on the other side of the flipping plate 202 ensures that the single paper roll is stably released to the chain conveyor 3. The limiting mechanism 4 of the chain conveyor 3 adjusts the position of the limiting plate 402 through the second hydraulic push rod 403 to further constrain the rolling range of the paper roll, so that the packaging paper roll 6 rolls stably on the chain conveyor 3, and finally realizes the automated and precise unloading and conveying of the packaging paper roll 6.
