Description

Technical Field

It can stack multiple layers, and then push them out to facilitate forklifts to transport them to the warehouse for storage. The fixture structure of the palletizer should be able to be adjusted according to the size of the outer packaging. For example, the Chinese utility model type patent with announcement number: CN209427740U discloses a palletizer with adjustable stacking size. The utility model uses a first motor and a rotating shaft to rotate the rotating shaft, rotate the turntable, and cooperate with the first clamping plate and the second clamping plate on the sliding track plate to clamp the object, and then use a second motor and a threaded rod to rotate the threaded rod, and then cooperate with the rotation of the threaded rod to rotate the second clamping plate on the fixed block to adjust and clamp the object, thus solving the problem of stacking size adjustment;

[0003] However, when the device is in use, since the first clamp and the second clamp directly clamp the outer packaging, when the outer packaging is a thin carton, excessive pressure between the first clamp and the second clamp may cause deformation of the outer packaging and even damage the internal products. If the pressure between the first clamp and the second clamp is too small, the outer packaging may easily slip from between the first clamp and the second clamp when being transferred and moved, so improvement is needed.

[0024] like Figures 2 to 3 As shown, the buffer plate 411 is located at the side position of the fixed clamping tooth 409, the movable rod 413 is fixedly connected to the buffer plate 411, and the movable rod 413 and the fixed clamping tooth 409 are movably installed. The adjusting clamping assembly 4 also includes a buffer pad 412 and a spring 414. The buffer pad 412 is fixedly connected to the side position of the buffer plate 411, and the spring 414 is movably installed on the movable rod 413 and is located between the buffer plate 411 and the fixed clamping tooth 409. A through hole is provided on the fixed clamping tooth 409 at a position corresponding to the movable rod 413. The buffer pad 411 on the buffer plate 412 replaces the fixed clamping tooth 409 to contact the outer packaging. After the buffer plate 411 is subjected to pressure, it will move sideways, so that the spring 414 is compressed by the buffer plate 411, and the outer packaging box is buffered by the buffer pad 412 and the spring 414 to avoid excessive pressure and damage to the outer packaging.

The push rod 416 slides outward in the sliding groove 421 of the intercepting tooth 418, so that the intercepting tooth 418 rotates on the rotating rod 419 through the No. 2 bearing 420. The lower end of the intercepting tooth 418 passes through the slot 417 and moves to the position below the buffer pad 412, and moves to the position below the outer packaging to intercept the sliding outer packaging and prevent it from sliding out.

[0026] It should be noted that the utility model is a palletizer with adjustable palletizing size.
