Description

TECHNICAL FIELD

[0001] The utility model relates to a novel box sealing machine core structure. BACKGROUND

[0002] Carton packaging refers to the packaging of products with paper boxes in the flow process to protect products, facilitate storage and transportation, and promote sales. Carton packaging is the most widely used packaging method. In the existing carton packaging process, some need to fix the four corners with adhesive paper, which is usually attached by automatic adhesive paper equipment.

[0003] The current box sealing machine core, such as the corner edge sealing machine disclosed in Chinese Patent No. CN216637032U, includes a connecting plate, a connecting arm, a tape holder, a first sleeve, a second sleeve, and other components. The core can drive the tape to adhere to the top and bottom sides of the product. After the tape is attached to the product, the edge sealing cylinder will act, and the brush sealing plate will move, folding the excess part of the tape on the side of the product to adhere to the side wall of the product, thereby achieving edge sealing and preventing the phenomenon of misalignment.

[0004] In summary, the current box sealing machine core can only satisfy the planar attachment and packaging of the top and bottom sides of the packaging box. When the core is applied to the corner edge packaging of the packaging box, the tape needs to be attached to the edge of the packaging box first, and a part of the tape protrudes outward from the side of the packaging box. Then, the edge sealing cylinder drives the brush sealing plate to move, and the brush sealing plate folds the excess part of the tape on the side of the product to adhere to the side wall of the product. As can be seen from the above, the current box sealing machine core cannot directly seal the edge of the packaging box, and a cylinder and a sealing plate need to be added to achieve the sealing, thereby increasing the production cost and failing to meet the use requirements.

[0005] Therefore, a new type of box sealing machine core structure is needed to improve the above-mentioned problems. UTILITY MODEL CONTENTS

[0012] In an embodiment, a mounting rack is further arranged on the rack for mounting and placing the adhesive tape roll.

[0013] In an embodiment, a reverse U-shaped pressing frame which can be movably abutted against the adhesive tape roll arranged on the mounting rack is rotatably arranged on the rack, and a second elastic member is arranged between the rack and the reverse U-shaped pressing frame to drive the reverse U-shaped pressing frame to be elastically abutted against the adhesive tape roll.

[0014] In an embodiment, a guide wheel shaft is further rotatably arranged on the rack between the mounting rack and the pressing wheel component.
