Description

Technical Field

[0001] This utility model relates to the field of box opening technology, specifically to a material placement rack for a box opening machine that facilitates box opening. Background Technology

[0002] In the packaging industry, various box-opening mechanisms are widely used in automated production lines, warehousing and sorting, and retail displays. Their core function is to automatically open boxes to facilitate subsequent processes such as retrieval, filling, and sorting. Common box-opening mechanisms typically use the coordinated action of mechanical transmission components, such as linkages, gears, suction cups, and push rods, to apply a directional force to the box lid and body, thereby completing the opening action. Especially when picking up a box, a flexible abutment is needed to pre-open the box body to facilitate the subsequent insertion of the opening rod to complete the opening.

[0003] In practical applications, boxes are mostly made of paper or plastic. These materials are prone to generating static electricity during production, processing, stacking, storage, and transportation due to friction and contact separation. Because of the electrostatic adsorption effect, the lid adheres tightly to the box body, making it difficult for the elastic lever of the opening mechanism to overcome the adsorption force and open the box. This can lead to bending, tearing, or incomplete unfolding, hindering the subsequent insertion of the opening lever for opening. Therefore, there is an urgent need for a convenient box-opening machine material placement rack. Utility Model Content

[0004] This utility model aims to solve the technical problems existing in the prior art, and innovatively proposes a material placement rack for a box opening machine that facilitates box opening. It can pick up the box and assist in opening the box, thereby improving the box opening efficiency.

[0005] To achieve the above objectives, this utility model provides a material placement rack for a box-opening machine that facilitates box opening. The rack includes a frame with a ring of stacking racks forming a vertically connected stacking structure. The stacking racks on both sides of the packaging box are equipped with supporting pulleys for supporting the packaging box. The frame is also equipped with a pair of elastic abutments on the same side of the packaging box. The elastic abutments are used to abut against the side panel of the packaging box and open it when the suction cup of the packaging box is picked up. The stacking racks at both ends of the packaging box are respectively equipped with a first holding mechanism and a second holding mechanism for supporting the two ends of the packaging box. The supporting pulleys, the first holding mechanism and the second holding mechanism are flush and together support the circumferential edge of the packaging box.

[0006] The first support mechanism includes an L-shaped support member, the vertical portion of which is fixed to the bottom of the stacking rack, and the horizontal portion of which extends toward the inside of the stacking rack.

[0007] The second supporting mechanism includes a connecting rod with a fixing hole and is mounted on the outside of the stacking rack by mounting bolts. The connecting rod is inclined and has a horizontal abutment extending to the bottom of the box lid. The abutment is flush with the lateral portion of the L-shaped support and is used to hold the box lid. The length of the abutment extending to the bottom of the box lid is longer than the lateral portion of the L-shaped support. This allows the box to be pulled open by the abutment against the box lid when the suction cup of the external suction structure is used to move the box downwards.

[0008] In the above scheme: the abutment rod can be detachably installed on the connecting rod.

[0009] In the above solution: both ends of the connecting rod have pre-drilled mounting holes for the abutment rod to pass through. The abutment rod is threaded, and nuts located on both sides of the connecting rod are threaded onto the abutment rod. The position of the abutment rod and its length extending into the stacking rack are adjusted by the nuts. The threaded design allows for adjustment of the abutment rod's installation height and extension length via the nuts on both sides. The structure is simple, low-cost, and easy to adjust.

[0010] In the above scheme: the mounting hole is a strip-shaped hole, and the fixing hole of the connecting rod is connected to the mounting hole. They share a single hole.

[0011] In the above scheme: the stacking rack includes a vertically arranged upright, the bottom back of the upright is mounted on the frame by an L-shaped bracket, a rectangular frame is provided on the frame corresponding to the stacking rack, all stacking racks are set in the rectangular frame, the vertical part of the L-shaped bracket is fixedly connected to the upright, and a strip hole is provided on the horizontal part of the L-shaped bracket, and it is fixedly mounted on the frame by mounting bolts passing through the strip hole.

[0012] In the above scheme: the supporting pulley is rotatably installed on the inner side of the corresponding upright near the stacking frame. The upright is provided with a groove for accommodating the supporting pulley, so that only the supporting pulley side is outside the groove.

[0013] In the above solution: the elastic abutment includes an abutment body and an L-shaped mounting base. The top of the vertical portion of the mounting base is mounted on the frame, and the end of the horizontal portion of the mounting base extends toward the stacking rack. One end of the abutment body is hinged to the end of the horizontal portion of the mounting base, and a torsion spring is provided at the hinge point of the abutment body. The other end of the abutment body is inclined downwards, and the other end of the abutment body extends only to the direct underside of the nearest side panel of the packaging box.

[0014] In the above scheme: the frame is provided with a strip hole for the stacking rack with supporting pulleys to move.

[0015] In summary, the beneficial effects of this utility model are: it can form a support structure with a wider support surface at one end and a narrower support surface at the other end through the L-shaped brackets and abutment rods on both sides. The wider L-shaped brackets ensure stable support, while the narrower abutment rods are used to hold the lid open. This allows the lid to be opened while being sucked in, and the elastic abutment rods improve the efficiency of opening the box and facilitate subsequent opening operations.

[0019] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0020] like Figures 1-3 As shown, a material placement rack for a carton opening machine that facilitates box opening includes a frame 9. A stacking rack 1 is arranged around the frame 9, forming a vertically connected stacking structure. Suction cups 7 for picking up packaging boxes are also provided below the stacking structure. Packaging boxes are horizontally stacked on the stacking structure, and each box has a ring of side panels that are connected end-to-end to form a closed cylinder. Both ends of the packaging boxes have openings, and corresponding lids and flaps are provided.

[0021] Each of the stacking racks 1 located on both sides of the packaging box is equipped with supporting pulleys 3 for supporting the packaging box. The supporting pulleys 3 are located on the inner side of the stacking racks 1. The stacking racks 1 located at both ends of the packaging box are respectively equipped with a first supporting mechanism and a second supporting mechanism for supporting both ends of the packaging box. The supporting pulleys 3, the first supporting mechanism and the second supporting mechanism are flush and together support the circumferential edge of the packaging box.

[0022] The frame 9 is equipped with a pair of elastic abutments located on the same side of the packaging box. The elastic abutments are located below the supporting pulley 3. The elastic abutments are used to abut against the side plate of the packaging box when the suction cup 7 of the packaging box is picked up, thereby opening the packaging box.

[0023] The first support mechanism includes an L-shaped support 5. The vertical part of the L-shaped support 5 is fixed to the bottom of the stacking rack 1, and the horizontal part of the L-shaped support 5 extends towards the inside of the stacking rack 1.
