[0002] Packaging cartons are widely used in the packaging of various products, especially the packaging of various medical devices, such as various syringes, etc. Figure 7 As shown, a common syringe packaging box is designed with inner tongues 191 at both ends of the upper opening of the box body 19 and an upper cover 192 with a front tongue 193 on one side. Before the product is loaded, the inner tongues 191 at both ends are folded inward to a horizontal state. When the product is loaded, it contacts the inner tongues 191 at both ends and is pressed into the box body, and the inner tongues play a role in supporting and protecting the product; finally, the upper cover 192 is folded inward to cover the upper opening of the box body, and after the cover is closed, it is glued to the front of the box body and fixed by the front tongue 193.

[0003] The box-sealing machines currently on the market usually work better for paper boxes with smaller edges. They usually fold the paper boxes by swinging a swing rod or a swinging piece. However, this mechanism can only fold and seal the paper boxes one by one, which is inefficient. Moreover, the front tongue of the top cover of the paper box after sealing is attached to the front of the packaging box, making it difficult for end users to open the box and wasting glue. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a multi-station paper box sealing mechanism which can realize automatic folding and sealing of upper covers of multiple packaging paper boxes at the same time and has high working efficiency.

[0007] The box sealing fixture includes a base plate evenly suspended under the mounting frame through a connecting frame, and two suction cups are symmetrically arranged at the front end of the base plate for sucking the box body on one side of the upper cover of the paper box; a folding plate is hinged on the front side of the base plate, and a folding cylinder is arranged between the base plate and the folding plate for driving the folding plate to flip and realize folding the upper cover of the paper box; the folding plate is L-shaped and tongue-pressing cylinders are symmetrically arranged on the vertical plate at the front end of the bottom of the folding plate for sticking the glue-coated front tongue of the upper cover to the other side of the box body.

[0008] As a further preference, the connecting assembly includes a connecting column and a connecting seat, the connecting column is fixed to the lower end of the Z-axis slide, and the connecting seat is composed of a connecting base plate and two connecting blocks symmetrically fixed on the connecting base plate. The lower end of the connecting column is a cube, which is inserted between the two connecting blocks and connected to each other through a thumb-type lock to facilitate rapid disassembly and replacement of the mounting frame and the sealing clamp.

[0009] As a further preference, a clamping plate is fixed at the lower end of the connecting column, and a pair of limiting clamping blocks are respectively provided between the two ends of the clamping plate and the two connecting clamping blocks to reduce the load of the thumb-type locker.

[0010] As a further preference, support arms are symmetrically fixed on both sides of the folding pressure plate, and the folding pressure plate is overlapped with the base plate through the support arms on both sides and is hinged on the base plate through a pin shaft and a bearing.

[0011] As a further preference, the tongue depressor cylinder is a bolt cylinder.

Since a plurality of box sealing fixtures are evenly distributed on the mounting frame, the two suction cups symmetrically arranged at the front end of the base plate of each box sealing fixture can suck the box body surface on one side of the upper cover of the paper box; the folding cylinder arranged between the base plate and the folding plate can drive the folding plate to flip and realize the folding of the upper cover of the paper box; the tongue pressing cylinder symmetrically arranged on the front end vertical plate at the bottom of the folding plate can paste the glued front tongue of the upper cover on the other side of the box body, so that the automatic folding and sealing of the upper covers of multiple packaging paper boxes can be realized at the same time, and the working efficiency is high.

[0015] 2. Since tongue-pressing cylinders are symmetrically arranged on the vertical plate at the front end of the bottom of the folding plate, the glued front tongue of the upper cover can be pasted to the other side of the box body, so that the glue coating point of the front tongue of the upper cover can be accurately pressed, which can avoid the entire front tongue of the upper cover of the paper box being pasted to the front of the packaging box, causing difficulty for the end user to open the box.
