Description

TECHNICAL FIELD

[0001] The utility model relates to the field of packing machine, concretely relates to a packing machine's push closing box mechanism. BACKGROUND

[0002] With the rapid development of the packaging industry, the requirements for packaging equipment are also increasing. In the packaging process, closing and pushing the box operation is one of the key links. However, the current closing and pushing mechanism generally has the problem of inconvenient adjustment. Especially for the adjustment of the height and width of the box, a complex operation process and multiple steps are often required, which consumes a lot of time and manpower, seriously affecting the production efficiency. In addition, during the closing process, it is difficult to ensure that the closing effect of boxes of different sizes is consistent, and situations such as loose closing may occur. At the same time, when pushing the box, because the mechanism does not match the box, it may cause unstable box conveying, and even the phenomenon of box dumping.

This technical solution adjusts the distance between the two first mounting bases by setting the width adjustment component. In addition, the upper conveyor belt component, the lower conveyor belt component, the upper guide component, and the lower guide component on the first mounting base can all achieve distance adjustment, so that the conveying component and the box closing component can be adapted to cartons of different sizes, ensuring tight box closing and stable box pushing, and improving packaging production efficiency.

[0057] The width adjustment assembly 25 includes a threaded adjustment screw 251 and a plurality of adjustment nut sleeves 252. The adjustment screw 251 has two sections of threads with opposite directions of rotation, and the adjustment nut sleeves 252 are fixedly installed at the top position of the first mounting base 23.

[0058] The end of the adjusting screw 251 is provided with an adjusting shaft 253 and a coupling 254 that links the two together.

[0059] A first sliding module 26 is provided between the lower surface of the second mounting base 24 and the top of the first mounting base 23 to achieve sliding cooperation between the two. When the operator rotates the adjusting shaft, the adjusting screw rotates synchronously through the coupling. When the adjusting screw rotates, it causes the first mounting bases on both sides to move synchronously towards or away from each other through the adjusting nut sleeve and the two-stage threads. The first sliding module adopts a slide rail and a slider.

The first lead screw 2311 is rotatably mounted on the first mounting base 23, and the first nut sleeve 2312 is fixedly connected to the upper conveyor belt component 211. The rotation of the first lead screw drives the upper conveyor belt component on the first nut sleeve to move up and down.

[0084] The second lifting assembly 234 includes a threaded second lead screw 2341 and a second nut sleeve 2342. The second lead screw 2341 is rotatably mounted on the first mounting base 23 and is arranged parallel to the first lead screw. The second nut sleeve 2342 is fixedly connected to the central guide component 222. The rotation of the second lead screw drives the central guide component on the second nut sleeve to move up and down.
