Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of palletizing equipment, and more specifically, to an expansion device. Background Art
[0002] When palletizing boxes in a carriage, the boxes need to be placed side by side. However, the width of the carriage is limited. To ensure space utilization, the length of a row of boxes will be just equal to or slightly greater than the width of the carriage. For example, a carriage with a width of 2350mm will hold 5 boxes with a width of 470mm. When palletizing manually, the last box in each row can be forcibly inserted by workers. However, when palletizing by palletizing machinery, the movement of the palletizing machinery will produce errors, resulting in insufficient space reserved for the last box in the same row, which will prevent the box from being placed in, thus affecting normal palletizing.

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figures 1 to 4, an expansion device includes a support plate 100, which is installed at the end of the conveying direction of the conveying mechanism 600 and can be extended and retracted relative to the conveying mechanism 600. A support block 110 is fixed on the support plate 100, and a fixed plate 400 is fixed to the support block 110. The space between the support plate 100 and the fixed plate 400 constitutes an installation space. Two rotatable rod bodies 300 are installed in the installation space, and the rotation directions of the two rod bodies 300 are opposite. A power source 101 is installed on the support plate 100, and the power source 101 is a cylinder. A driving member 200 is connected to the output end of the power source 101, and the driving member 200 is connected to the rod body 300. The movement of the driving member 200 can drive the rotation of the rod body 300. The edge of the support plate 100 and the edge of the fixing plate 400 form an opening 410 of the installation space. The rotation of the rod body 300 can make the end of the rod body 300 extend out of the installation space through the opening 410, thereby pushing the boxes on both sides of the support plate 100 away to expand the space for placing the last box.
[0021] A mounting hole 330 is provided in the middle of the rod body 300, and a support shaft 500 is fixed on the support plate 100. During installation, the support shaft 500 is passed through the mounting hole 330 and connected to the mounting hole 330 through a bearing 510, so that the rod body 300 can rotate on the support shaft 500. A groove 340 is provided in the middle of the rod body 300, and the two rod bodies 300 are arranged up and down, with the groove 340 of the upper rod body 300 facing downward, and the groove 340 of the lower rod body 300 facing upward, and the grooves 340 of the two rod bodies 300 are interlocked, so that the two rod bodies 300 form an X-shaped structure.
[0022] The two sections of the driving member 200 are provided with guide grooves 220, and the two rod bodies 300 respectively pass through the two guide grooves 220. At the same time, a slide groove 310 is provided on the rod body 300, so that the slide groove 310 also passes through the guide groove 220. A sliding member 210 is installed in the guide groove 220. The sliding member 210 is a columnar structure. The sliding member 210 is inserted into the slide groove 310 so that the sliding member 210 can move along the slide groove 310. When the driving member 200 moves, the sliding member 210 is driven to move, so that the moving member is in the slide groove 310 to promote the rotation of the rod body 300.
[0023] A contact piece 320 is disposed at the end of the rod body 300, and a curved surface 321 is disposed on the contact piece 320. When the rod body 300 extends out of the installation space, the curved surface 321 on the contact piece contacts the box body, thereby protecting the box body.
[0024] During palletizing, the boxes on both sides of the same row are placed first, thereby leaving a position in a row of boxes. Then, when placing the last box, the support plate 100 is extended to the reserved position and the driving member 200 is used to push the rod body 300 to rotate so that the contact member 320 at the end of the rod body 300 contacts the boxes on both sides. The rod body 300 is continued to be pushed to rotate so that the end of the rod body 300 pushes the boxes on both sides to be squeezed to both sides respectively, thereby expanding the space of the reserved position so that the last box in this row can be placed smoothly.
[0025] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
