Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper box production, in particular to a corrugated paper core smoothing device. Background Art

[0002] Corrugated paper, also known as corrugated cardboard, is made of at least one layer of corrugated paper and one layer of boxboard. It has good elasticity and extensibility and is mainly used to make cartons, carton cores and other packaging materials for fragile goods. Usually when preparing corrugated paper, the paper core cannot be completely smoothed when the roller pulls it, so the paper core is prone to have wrinkles on the surface after processing.

[0003] After searching, the patent document with the authorization publication number CN216444718U in the related technology discloses a corrugated paper core smoothing device, including a bracket, a towing platform fixedly connected to the left side of the bracket, a smoothing platform fixedly connected to the top of the towing platform, a metal partition fixedly connected to the top of the smoothing platform, a steel ball movably connected to the right side of the metal partition, a U-shaped clamp block movably connected to the outside of the bracket, a movable hinge plate movably connected to the top of the U-shaped clamp block, a fixing screw threadedly connected to the top of the movable hinge plate, a connecting platform fixedly connected to the bottom of the movable hinge plate, and a swing plate movably connected to the middle of the connecting platform. The corrugated paper smoothing device drives the swing plate to run through the push rod, and the swing plate drives the fixed rod to run, and then through the coordinated use of the rolling shaft, the universal joint, the motor and the roller, the wrinkles on the surface of the wrinkled paper core are pressed back under the rolling and pressing action of the roller, and will not bulge again to form wrinkles, which provides a guarantee for subsequent good production.

[0004] Regarding the above-mentioned related technologies, the utility model inventor believes that there are the following defects:

[0005] 1. The above device drives the swing plate to operate through the push rod, and the swing plate drives the fixed rod to operate, and then the rolling shaft, universal joint, motor and roller are used in coordination, so as to achieve the effect of smoothing the wrinkled paper core. Under the rolling and pressing action of the roller, the raised wrinkles on the surface of the wrinkled paper core are pressed back and will not be raised again to form wrinkles, which provides a guarantee for subsequent good production. However, during the smoothing process, the above device uses the roller to continuously swing back and forth to perform the smoothing work, which lacks a buffering effect. Therefore, for corrugated paper cores with larger curvatures, it is easy to damage the internal structure of the corrugated paper core.

[0006] Therefore, it is necessary to provide a new corrugated paper core smoothing device to solve the above technical problems. Utility Model Content

[0031] The working principle of the corrugated paper core smoothing device provided by the utility model is as follows:

[0032] The first step: when loading the corrugated paper core, pull the pull rope 22, and the pull rope 22 drives the two limit plugs 19 to move closer to each other, and the two limit plugs 19 drive the two extrusion blocks 20 to move and squeeze the telescopic spring 21. During the movement of the limit plug 19, it will be separated from the limit plug hole on the limit plug 33, and then open the limit plate 34. Although the corrugated paper core is slid into the placement frame 3, the operation is simple, and the loading limit of the corrugated paper core can be performed to prevent the corrugated paper core from being offset in the subsequent smoothing work and affecting the smoothing effect. Similarly, the limit plate 34 can be installed;

[0033] The second step: start the servo motor 13, and drive the threaded rod 14 to rotate through the servo motor 13. Under the limiting action of the thread, the limiting rod 16 and the moving block 17, the threaded rod 14 and the moving block 17 can drive the placement frame 3 to move, and at the same time start the electric push rod 6, and drive the moving plate 4, the three sets of spring support rods 12 and the elastic metal plate 10 to move downward and fit tightly with the corrugated paper core through the electric push rod 6, and then close the electric push rod 6. When the moving corrugated paper core passes through the elastic metal plate 10, the elastic metal plate 10 can be used to smooth the corrugated paper core, and at the same time, the spring support rod 12 can continuously apply downward pressure to the elastic metal plate 10, which can improve the smoothing effect. At the same time, the spring support rod 12 can have a buffering effect, which can avoid excessive downward pressure from damaging the internal structure of the corrugated paper core;

[0034] The third step: after smoothing, the placement frame 3 is moved to the rear, and the limiting plate 34 is opened in the same manner as above, and then the corrugated paper core is slid out, and then the same steps as above are performed to load and smooth the corrugated paper core.
