Technical Field

[0001] The utility model relates to the technical field of product wrapping for warehouses, in particular to a full-automatic pallet wrapping machine for warehouses. Background Art

[0002] In the prior art, after the product is produced, it is necessary to use stretch film to package and repackage the product. The stretch film can protect the product to a certain extent. The product needs to be packaged before it can be put on the market for sale. In the process of packaging the product, a pallet stretch film packaging machine is required.

[0003] In the existing technical solutions, for example, the document with the publication (announcement) number: CN212638011U discloses "a movable wrapping machine", in which universal wheels and running wheels are provided, and a turntable is provided on the bottom plate, and a mobile mechanism is used to realize product packaging.

[0004] However, the width of the wrapping arm of the above-mentioned technical solution and the existing pallet wrapping film is usually not adjustable during wrapping, and even if the width can be adjusted, the adjustment method is not very convenient. It is also a common problem that the width cannot be effectively fixed after adjustment, resulting in a small overall application range of the equipment and poor work efficiency.

[0005] Therefore, in order to solve the above problems, it is necessary to develop a fully automatic pallet wrapping machine for warehouses that can adjust the width range and can be effectively fixed accordingly. Utility Model Content

Internal threaded sliders are installed at both ends of the sliding bidirectional screw rod, and one side end of the sliding bidirectional screw rod extends out of the slide groove and is correspondingly installed with a rotating wheel, and a limiting mechanism is correspondingly installed at the rotating wheel; and downwardly extending fixed rods are also installed on the internal threaded sliders on both sides, and a rotating drum is provided on the fixed rod, and the film body used for wrapping is correspondingly wound on the rotating drum.

[0009] Furthermore, a position-adjustable sleeve-type baffle is installed at the lower end of the fixing rod, and the rotating drum is correspondingly blocked by the sleeve-type baffle.

[0010] Furthermore, a limiting hole is provided at the lower end of the fixing rod, and a limiting bolt corresponding to the position of the limiting hole is provided on the sleeve-type baffle, and the position of the sleeve-type baffle is adjusted accordingly through the cooperation between the limiting hole and the limiting bolt.

[0011] Furthermore, the threads on both sides of the sliding bidirectional screw rod are arranged as two separate sections, and the directions of the two sections of threads are arranged in opposite directions, so that after the rotating wheel rotates, the internal thread sliders on both sides move inward or outward at the same time.

[0012] Furthermore, the limiting mechanism comprises a limiting plate extending from the upper end of one side of the crossbar, a vertical pull rod is mounted on the limiting plate, a concave plate is disposed at the bottom of the pull rod, and a spring member is disposed between the concave plate and the limiting plate;

[0031] The lifting mechanism 13 of the present embodiment is configured as a hydraulic cylinder, and the rotating mechanism 14 of the present embodiment is configured as a rotating motor.

[0032] The working principle of the technical solution of this embodiment is as follows: place the products to be packaged on the pallet base, and then adjust the width between the rotating drums on both sides according to the placement position and size of the products, and specifically adjust the distance between the two rotating drums by rotating the wheels.

[0033] A slide groove is provided in the cross bar, and a bidirectional screw rod is installed in the slide groove. Internal threaded sliders are installed at both ends of the bidirectional screw rod. A rotating wheel is installed after one end of the bidirectional screw rod is extended. At the same time, the thread directions of the two ends of the bidirectional screw rod need to be set in opposite directions. In this way, when the rotating wheel is rotated, the rotating drums on both sides can be approached or moved away at the same time. After adjusting the position, the rotating mechanism can be started to drive the rotating drums on both sides to rotate. The rotating drum is wrapped with a film body, so that the products on the pallet base can be packaged and wrapped.

[0034] In this embodiment, the sleeve-type baffle plate at the lower end of the fixed rod and the lifting mechanism can adjust the height of the rotating drum accordingly. After adjusting the width, it can adapt to products of different sizes, and the structural setting is reasonable.

[0038] In this embodiment, a position-adjustable sleeve baffle 6 is also installed at the lower end of the fixed rod 5 , and the rotating drum 3 in this embodiment is correspondingly blocked by the sleeve baffle 6 .

[0039] In this embodiment, a limiting hole 4 is provided at the lower end of the fixing rod 5, and a limiting bolt 8 corresponding to the position of the limiting hole 4 is provided on the sleeve baffle 6 of this embodiment. The position of the sleeve baffle 6 is adjusted accordingly by the cooperation between the limiting hole 4 and the limiting bolt 8.

[0040] In this embodiment, the threads on both sides of the bidirectional screw rod 9 are arranged as two separate sections, and the directions of the two sections of threads are arranged in opposite directions, so that after the rotating wheel 11 rotates, the internal thread sliders 2 on both sides move inward or outward at the same time.

[0041] The limiting mechanism 12 of this embodiment includes a limiting plate 21 extending from the upper end of one side of the crossbar 1, a vertical pull rod 20 is installed on the limiting plate 21, and a concave plate 18 is arranged at the bottom of the pull rod 20, and a spring member 17 is also arranged between the concave plate 18 and the limiting plate 21;

[0042] In this embodiment, a hexagonal block 19 is correspondingly installed on the rod body of the sliding bidirectional screw rod 9 extending out of the slide groove 10.
