Description

Technical Field

[0001] The utility model relates to the technical field of mechanical clamps, in particular to a clamp capable of sucking a box without removing a tape. Background Art

[0002] Traditional clamps can deform cartons due to uneven suction force. The glue seam pressure plate helps balance the force by pressing the tape as the suction cups hold the cartons in place. Often, the tape on the cartons can warp due to various reasons, such as loose adhesion or prolonged use. This warped tape can affect the grip and easily cause the cartons to fall off. Therefore, we developed a clamp that allows the cartons to be held in place without the tape falling off. Utility Model Content

[0003] The purpose of the utility model is to provide a clamp for sucking a box without removing the tape, so as to solve the problems raised in the above background technology.

[0004] To achieve the above object, the utility model provides the following technical solutions: a clamp for sucking a box without removing the tape, comprising a flange connecting rod, a fixing plate and a suction cup;

[0005] The fixing plate is cross-shaped, and a flange connecting rod is installed in the middle of the top of the fixing plate by bolts. Two suction cups are provided, and the two suction cups are symmetrically distributed below the fixing plate. A glue seam pressing plate is provided between the two suction cups, and the glue seam pressing plate and the suction cups are parallel to each other. Sliding grooves are symmetrically opened on the tops of the two suction cups.

[0006] The fixing plate and the suction cup are both perpendicular to each other and are equipped with locking blocks. The locking blocks are both provided with extended edges near the sliding grooves, and screw holes are provided on the extended edges. Bolts are installed in the screw holes, and the nut ends of the bolts are slidably engaged in the sliding grooves. The top of the glue seam pressure plate is symmetrically equipped with pressure plate adjustment rods. The pressure plate adjustment rods are distributed at both ends of the glue seam pressure plate, and the pressure plate adjustment rods extend upward into the fixing plate.

[0007] An elastic pressure structure is provided above the fixed plate, and the elastic pressure structure consists of an adjustment plate, a limit frame and a spring. Two adjustment plates are provided, and a disc is provided between the two adjustment plates, and the disc is movably sleeved on the flange connecting rod.

[0008] Preferably, when the suction cups are adsorbed on the carton, the glue seam pressing plate located between the two suction cups presses the tape, so that the suction cups are subjected to balanced forces when adsorbing the carton, and the carton will not be deformed when moving.

[0009] Preferably, the two adjustment plates are fixed to each other with the disc by bolts, and finger rings are welded on the two adjustment plates near the flange connecting rod; a limit frame is provided on the outer side of both ends of the adjustment plate, and the bottom of the limit frame is fixed to the fixed plate by bolts; a spring is installed between the bottom of the limit frame and the adjustment plate; the bottom of the adjustment plate is connected to the top of the pressure plate adjustment rod.

[0010] Preferably, insert your finger into the finger ring and pull the adjustment plate upwards, the adjustment plate drives the glue seam pressure plate to move up through the pressure plate adjustment rod, and when the adjustment plate is pulled upwards, the glue seam pressure plate is raised, and after the restraint is released, the adjustment plate and the glue seam pressure plate are pushed downwards by the action of the spring, and pressure is applied to the glue seam pressure plate by the spring, so that the glue seam pressure plate is pressed tighter.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The fixture is equipped with two symmetrically distributed suction cups. This symmetrical structure provides a relatively balanced suction force when sucking the carton. During the suction process, all parts of the carton are evenly stressed, effectively avoiding the problem of carton deformation caused by excessive or insufficient local force. It is especially suitable for handling cartons that require high shape retention.

[0013] The presence of the glue seam pressure plate further enhances stability. When the suction cup absorbs the carton, the glue seam pressure plate presses the tape, making the connection between the entire clamp and the carton more stable. On the basis of suction, a fixed point is added to prevent the carton from loosening or falling off during movement due to the special position of the tape (such as the tape may warp). In addition, the components are fixed with bolts and other connectors, which facilitates assembly and disassembly. In the event of a malfunction or maintenance of the clamp, the various components can be easily inspected and replaced.

[0014] Moreover, the spring applies pressure to the glue seam pressing plate, so that the glue seam pressing plate is pressed more tightly while having a certain elasticity. BRIEF DESCRIPTION OF THE DRAWINGS
