Description

Technical Field

[0001] This utility model relates to the field of conveyor equipment technology, specifically to an arc-shaped enclosure component for a corrugated cardboard turning conveyor. Background Technology

[0002] Corrugated cardboard turning conveyors are key equipment in modern carton packaging production lines, playing a crucial role in changing the direction of cardboard transport. In automated production lines, to meet the spatial layout requirements of processes such as sorting, stacking, and printing, cardboard often needs to undergo multiple angle changes during transport. The stability of the turning process directly affects the edge crush strength and surface quality of the cardboard, especially for high-grammage, multi-layered, premium packaging cardboard, where maintaining the integrity of its flute structure and surface printing layers is paramount.

[0003] The shortcomings of existing technology: Currently, mainstream turning conveyors employ conical roller assembly technology. By precisely calculating the diameter of each section of the conical rollers, a linear velocity difference is created between the outer and inner sides of the turning area, using this velocity difference to achieve the curved motion of the cardboard. However, this technology has a significant drawback. When the cardboard enters the turning area at a high speed from the straight section, due to inertia, it maintains its original motion trend, causing its outer edge to collide violently with the inner wall of the turning conveyor. This collision not only leads to deformation of the cardboard edges and corners and surface scratches but may also damage the corrugated structure, reducing edge crush strength and affecting the overall product quality. To avoid this problem, existing equipment typically limits the operating speed, but this severely restricts the improvement of production line efficiency. Utility Model Content

A conveyor belt, which is sleeved on the outside of the positioning post and the rotating post, is used to limit the end of the cardboard and assist in its turning. The arc-shaped positioning plate limits the curvature of the conveyor belt through the positioning post and the rotating post below it.

[0007] Preferably, the leveling component includes: A sliding sleeve, a plurality of the sliding sleeves are disposed on the outer arc side of the turning conveyor table, and the sliding end of the sliding sleeve is connected to the upper end face of the arc-shaped positioning plate for suspending the arc-shaped positioning plate; The motor is located on the outer arc side of the steering conveyor table.

[0018] Please see Figure 1-5As shown, this utility model provides a technical solution for an arc-shaped enclosure component for a corrugated cardboard turning conveyor: An arc-shaped enclosure component for a corrugated cardboard turning conveyor includes a turning conveyor table 1. Conveyor rollers 2 are installed at both ends of the conveying trough of the turning conveyor table 1. Several conical turning rollers 3 are arranged in the arc-shaped area of ​​the conveying trough of the turning conveyor table 1 for cardboard turning. The conveyor rollers 2 are installed horizontally or vertically on the outside of the arc-shaped area of ​​the conveying trough of the turning conveyor table 1 for horizontal cardboard transport. A power unit is installed inside the housing of the turning conveyor table 1 to provide power output to the conveyor rollers 2 and the conical turning rollers 3. A horizontal adjustment component 4 is installed on the outer arc side of the turning conveyor table 1. An enclosure component 5 for adjusting the cardboard turning is installed at the output end of the horizontal adjustment component 4. The enclosure component 5 is adjusted horizontally by the horizontal adjustment component 4. A transmission component 6 is installed between the conveyor rollers 2 and the enclosure component 5.

[0019] The enclosure assembly 5 includes an arc-shaped positioning plate 501 and a conveyor belt 504. The arc-shaped positioning plate 501 is installed at the output end of the horizontal adjustment assembly 4. Several positioning posts 502 and rotating posts 503 are rotatably mounted on the lower end of the arc-shaped positioning plate 501 via a mounting shaft, and the rotating posts 503 are located at the ends of the arc-shaped positioning plate 501. The conveyor belt 504 is sleeved on the outside of the positioning posts 502 and rotating posts 503 to limit the end of the cardboard and assist in its steering. The arc-shaped positioning plate 501 limits the curvature of the conveyor belt 504 through the positioning posts 502 and rotating posts 503 below it. The rotating posts 503 receive power from the conveyor roller 2 through the transmission assembly 6 to drive the conveyor belt 504 to rotate.

[0020] The length of the installation area for the conveyor rollers 2 on the steering conveyor table 1 is determined according to the horizontal conveying requirements of the corrugated cardboard. For example... Figure 5 As shown, when the corrugated cardboard moves from the conveyor roller 2 to the area of ​​the conical turning roller 3, it begins to turn under the action of the conical roller. At the same time, due to the inertia of horizontal forward movement, the front end of the corrugated cardboard first contacts the conveyor belt 504, and then turns along the inner arc of the conveyor belt 504 under the drive of the conveyor belt 504. It will not collide with the inner side of the turning conveyor table 1 due to inertia. Finally, after completing the turning and moving onto the conveyor roller 2, it is output horizontally.

[0021] The enclosure component 5 enables active guidance of the corrugated cardboard when it turns, preventing damage to the front end caused by the cardboard colliding with the conveyor table due to inertia. Furthermore, the conveyor belt 504 maintains active rotation both when and after contact with the cardboard, preventing friction with the corners of the cardboard. This increases the upper limit of the transport speed while ensuring the overall quality of the cardboard. Under the guidance of the conveyor belt 504, the cardboard can still be output in a state parallel to the conveyor roller 2 after turning, ensuring the conveying posture after the turning is completed.

[0022] The horizontal adjustment assembly 4 includes a sliding sleeve 401 and a motor 402. Several sliding sleeves 401 are fixedly installed on the outer arc side of the steering conveyor table 1. The sliding end of the sliding sleeve 401 is connected to the upper end face of the arc-shaped positioning plate 501 for suspending the arc-shaped positioning plate 501. The motor 402 is mounted on the outer arc side of the steering conveyor table 1 via a bracket. A lead screw 403 is installed at the output end of the motor 402. A telescopic sleeve 404 is installed at the end of the sliding part of the lead screw 403. The end of the telescopic sleeve 404 is connected to the upper end face of the arc-shaped positioning plate 501 for pushing the arc-shaped positioning plate 501 to move horizontally.

[0023] like Figure 5 As shown, before the cardboard begins to be conveyed, since the path and posture of the cardboard are fixed during straight-line conveying, the position of the barrier assembly 5 can be initially adjusted according to the path requirements of the cardboard. This ensures that the cardboard contacts the lower end of the conveyor belt 504 as early as possible when entering the curve, improving the turning effect. If the cardboard is close to the right side of the conveyor roller 2 before entering the curve, it will directly contact the upper end of the conveyor belt 504 after entering the curve, which will also cause some impact and this situation needs to be avoided. When it is necessary to adjust the horizontal position of the barrier assembly 5, the motor 402 is started to drive the lead screw 403 to rotate a certain distance in the specified direction. During this process, the sliding sleeve 401 extends and retracts synchronously with the horizontal movement of the arc-shaped positioning plate 501.

[0024] The horizontal adjustment component 4 enables precise adjustment of the horizontal position of the conveyor belt 504, thereby adapting it to different bend positions of the cardboard and ensuring that the cardboard can contact the conveyor belt 504 immediately after entering the bend, thus ensuring the turning effect.

[0025] The transmission assembly 6 includes a positioning frame 601 and a timing belt 605. The positioning frame 601 is fixedly mounted on the outer arc side of the steering conveyor table 1. A rotating sleeve 602 is rotatably mounted on the positioning frame 601. The rotating sleeve 602 is parallel to the conveyor roller 2 in any horizontal direction. A square shaft 603 is slidably connected to the inner side of the rotating sleeve 602. When the rotating sleeve 602 rotates, the square shaft 603 also rotates synchronously. Meshing bevel gears 604 are installed at the end of the square shaft 603 and the upper end of the shaft of the rotating column 503. The timing belt 605 is sleeved on the body of the rotating sleeve 602 between the rotating sleeve 602 and the roller shaft of the conveyor roller 2 below the rotating sleeve 602. This conveyor roller 2 can be the last conveyor roller 2 that the cardboard passes through before entering the bend. The timing belt 605 is used to output power from the conveyor roller 2 to the rotating column 503. A positioning nut 8 for positioning the square shaft 603 is installed on the rotating sleeve 602. When the conveyor roller 2 rotates, the synchronous belt 605 drives the upper rotating sleeve 602 to rotate. The square shaft 603 inside the rotating sleeve 602 rotates synchronously. The square shaft 603 then drives the rotating column 503 to rotate through the bevel gear 604 at its end. By adjusting the gear ratio of the two bevel gears 604, the rotational speed of the rotating column 503 can be adjusted, thereby adjusting the moving speed of the conveyor belt 504 so that the moving speed of the conveyor belt 504 can be kept consistent with the moving speed of the cardboard. When the horizontal adjustment component 4 needs to adjust the horizontal position of the conveyor belt 504, the positioning nut 8 is loosened. At this time, the square shaft 603 can extend and retract within the rotating sleeve 602 to adjust the position of the square shaft 603 and ensure the meshing between the bevel gears 604.

[0026] Through the transmission component 6, the synchronous belt 605 is driven by the power of the transmission roller 2. At the same time, the square shaft 603 can flexibly adjust the extension and retraction within the rotating sleeve 602 to ensure that the transmission effect is not interfered with by the horizontal adjustment component 4.

[0027] A suspension frame 7 is installed on the outer arc side of the steering conveyor 1 and at the end away from the rotating column 503. The suspension frame 7 is slidably connected to the upper end face of the arc-shaped positioning plate 501, ensuring the suspension stability of the far end of the arc-shaped positioning plate 501.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
