Description

Technical Field

[0001] This utility model relates to the field of tea packaging, and in particular to an adhesive applicator for sealing tea outer packaging boxes. Background Technology

[0002] Packaging boxes are widely used in daily life, such as for food packaging, clothing packaging, and express delivery packaging. They are also needed in tea packaging, for example, to package bagged tea.

[0003] For boxed tea, a six-sided cardboard box is generally used, which needs to be folded into shape. When boxing bagged tea, the cut cardboard board is first folded into an unsealed box shape, then the bagged tea is put into the cardboard box, glue is applied to the sealing side of the cardboard box, and finally the glued side of the cardboard box is sealed, thus completing the boxing of bagged tea.

[0004] When applying glue to unsealed cardboard boxes, manual glue application can result in low efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a gluing device for sealing tea outer packaging boxes, which solves the problem of low efficiency caused by manually applying glue to the surface of the packaging box when sealing the box.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a gluing device for sealing tea outer packaging boxes, including a frame, a gluing mechanism set on the frame, the gluing mechanism including a material guiding platform set on the frame, guide plates set on both sides of the material guiding platform, and an upper positioning plate set above each guide plate on the gluing frame; a guide gap adapted to the surface of the packaging box to be glued is formed between the guide plate and the upper positioning plate on the same side;

[0007] The gluing frame is located below the material guiding platform and is equipped with an open-top glue placement trough. Each gluing frame is equipped with a gluing wheel assembly on the outer side of each guide plate. Each gluing wheel assembly includes a rotatable upper positioning wheel and a rotatable lower gluing wheel. The upper positioning wheel is located on the outer wall of the upper positioning plate, and the lower gluing wheel is located on the outer wall of the guide plate. The lower part of the lower gluing wheel is located in the water placement trough. A gluing gap is provided between the upper positioning wheel and the lower gluing wheel to match the gluing surface of the packaging box.

[0008] Furthermore, the frame is also equipped with a transverse conveyor belt arranged along the X-axis and a pushing device arranged along the Y-axis; the pushing device and the guiding platform are respectively arranged on both sides of the discharge end of the transverse conveyor belt.

[0009] A set of partition plates is evenly spaced on the transverse conveyor belt, and the space between two adjacent partition plates forms a placement area that is compatible with the packaging box; the feed inlet of the material guide platform is compatible with the lateral opening of the placement area;

[0010] The pushing device includes a pushing cylinder mounted on the frame. The piston of the pushing cylinder is equipped with a pushing structure that can move with it. The pushing structure is adapted to the packaging box and is used to push the packaging box into and out of the guiding platform.

[0011] Furthermore, the pushing structure includes a lower pushing rod disposed on the piston part of the pushing cylinder, the lower pushing rod being adapted to the rear side of the packaging box; a vertical support part is provided at the end of the lower pushing rod, and an upper pushing rod with a length greater than the lower pushing rod is disposed on the vertical support part, the upper pushing rod being disposed parallel above the lower pushing rod; the upper pushing rod is located above the packaging box to be glued, and a downward pushing block is hinged to the front end of the upper pushing rod, the pushing block being adapted to the rear side of the packaging box; the distance between the pushing block and the top of the lower pushing rod is greater than the packaging box to be glued.

[0012] Furthermore, an upper limit plate is provided at the position where the transverse conveyor belt and the material guiding platform meet, and the upper limit plate is adapted to the upper end face of the packaging box to be glued; an upward arc-shaped notch is provided at the end of the upper positioning plate facing the unloading device.

[0013] The beneficial effects of this utility model are as follows: By cooperating with the material guiding platform and the guide gap, reliable transmission of the packaging box to be glued is achieved. With the glue application wheel set and glue placement groove, the glue application can be achieved on the surface to be glued during the transmission process of the packaging box. The whole structure is simple and reliable, and can achieve glue application on the surface to be glued in an efficient, convenient and reliable manner. It effectively solves the problem of low efficiency of manual glue application when sealing packaging boxes, where the glue application surface of the packaging box is brushed with glue manually.

[0014] The transverse conveyor belt and the pushing device work together to reliably transport the packaging boxes to be glued and feed them into the guiding platform. The two-stage pushing method of the lower pushing rod can reduce the stroke of the pushing cylinder. Combined with the hinged pushing block, it can stably and reliably push the packaging boxes to be glued into the guiding platform and push the packaging boxes out of the guiding platform after gluing. The structure is simple, reliable and easy to implement.

[0015] By setting an upper limit plate to limit the upper surface of the packaging box to be glued, the height and guide gap of the two sides to be glued that are connected to the upper surface of the packaging box are matched. Combined with the arc-shaped notch, it is easy for the two sides to be glued of the packaging box to reliably enter the guide gap when the pushing device pushes the material.
