Description

Technical Field

[0001] This utility model relates to the field of food packaging box technology, specifically to a device for removing excess glue from food packaging boxes. Background Technology

[0002] In the food packaging production process, the sealing or seams of packaging boxes usually need to be glued and fixed by a gluing process. However, due to the precision of the gluing equipment or the fluctuation of the process, excess glue is easily left on the surface of the packaging box (especially the top or edges). This residual glue not only affects the appearance of the product, but may also attract dust or impurities, reducing the hygiene and aesthetics of the packaging.

[0003] Existing adhesive removal devices often use a single blade or a fixed cutting structure, which makes it difficult to adapt to the adhesive removal needs of packaging boxes of different sizes and shapes. They are also sensitive to the viscosity or curing state of the adhesive, and are prone to problems such as missed cutting or over-cutting, which have certain limitations. Utility Model Content

[0004] The purpose of this utility model is to provide an excess glue removal device for applying glue to food packaging boxes, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an excess glue removal device for applying glue to food packaging boxes, comprising a base, a set of connecting frames provided at the middle of the top surface of the base, a set of clamping mechanisms connected to the bottom ends of the left and right sides of the connecting frames, and a set of glue removal mechanisms connected to the top of the connecting frames.

[0006] The connecting frame has a set of grooves at the rear middle end and the left and right sides near the front end. A set of screws is provided in the rear groove, and the top of the screws is connected to the drive motor. A set of guide rods is provided in the grooves at the left and right ends.

[0007] Preferably, all components of the clamping mechanism are identical. The clamping mechanism includes a recovery chamber, a spring, a push plate, and a clamping plate. A set of recovery chambers is connected to the bottom of both the left and right sides of the connecting frame. A set of push plates is connected to the side of the recovery chamber away from the connecting frame via a spring. The opposing surfaces of the two sets of push plates extend through to the bottom of the left and right sides of the connecting frame and are connected to a set of clamping plates.

[0008] Preferably, the adhesive removal mechanism includes a connecting frame, connecting blocks, electric push rods, and a drive mechanism. A set of connecting frames is provided at the top of the connecting frame, and a set of connecting blocks is provided at the corresponding groove positions on the outside of the connecting frame. The connecting blocks extend into the grooves and are connected to the screw and guide rod. A set of electric push rods is provided at the front middle of the connecting frame, and a drive mechanism is provided at the middle of the connecting frame.

[0009] Preferably, the driving mechanism includes a bottom groove, a recycling groove, and a de-adhesive blade. A set of bottom grooves is provided at the middle of the bottom surface of the connecting frame. A set of recycling grooves is provided at the left and right bottom ends of the bottom grooves. A set of de-adhesive blades is provided in both sets of recycling grooves.

[0010] Preferably, the rear end of the output end of the electric push rod extends through to the top of the bottom groove and is connected to a set of moving blocks. The bottom surface of the moving blocks is provided with no less than two sets of connecting arms on both the left and right ends. The other end of the connecting arms on the left and right ends is connected to the top surface of the two sets of adhesive removal blades on the left and right ends, respectively.

[0011] Preferably, a set of flanges is provided at the front and rear ends near the bottom of the recycling tank, and corresponding sliding grooves are provided at the front and rear ends of the adhesive removal blade.

[0012] Preferably, the bottom surface of the adhesive removal tool is flush with the bottom surface of the connecting frame.

[0013] Preferably, the connecting frame is inverted "T" shape.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The connecting frame located on the top surface of the base has a clamping mechanism at both the left and right bottom ends. The clamping mechanism includes components such as a recycling compartment, spring, push plate, and clamping plate. These components work together to clamp and fix the food packaging box. The top of the connecting frame has a glue removal mechanism, which includes components such as a connecting frame, connecting block, electric push rod, and drive mechanism. The connecting frame can move up and down within the connecting frame, and the drive mechanism removes excess glue from the food packaging box. This effectively avoids pulling or damaging the food packaging box during the removal process, ensuring the integrity of the food packaging box. The glue removal effect is good and it has strong practicality. Attached Figure Description

The food packaging box can be clamped and fixed by the clamping plates 34.

[0026] Please see Figure 2 and 4This utility model provides an excess glue removal device for food packaging boxes. The glue removal mechanism 4 includes a connecting frame 41, a connecting block 42, an electric push rod 43, and a drive mechanism 44. The top of the connecting frame 2 is provided with a set of inverted "T"-shaped connecting frames 41. A set of connecting blocks 42 are fixed at the corresponding positions of the grooves 21 on the back and left and right sides of the connecting frame 41. Each connecting block 42 has a through hole in the middle and extends into the groove 21. It is connected to the screw 22 and the guide rod 24 through the through hole. The inner side of the through hole of the rear connecting block 42 is provided with an internal thread. The rotation of the screw 22 can drive the connecting frame 41 to move up and down. The two sets of guide rods 24 can ensure the stability of the movement of the connecting frame 41. An electric push rod 43 is installed at the front middle of the connecting frame 41, and the drive mechanism 44 is provided in the middle of the connecting frame 41.

[0027] Please see Figure 4-5 This utility model provides an excess glue removal device for food packaging boxes.
