Description

Technical Field

[0001] The utility model relates to the technical field of rubber strip cutting equipment, in particular to a sealing rubber strip dovetail port beveling equipment. Background Art

[0002] Beveling of sealing strips, especially in the sealing needs of doors and windows, is to ensure that the sealing strips can better adapt to the installation environment and improve their sealing effect. This beveling process usually refers to processing one end of the sealing strip into a 45-degree bevel. This design enables the sealing strip to better fit the installation surface during installation, reduce gaps, and thus improve sealing performance.

[0003] The existing Chinese utility model patent with reference announcement number CN219132447U discloses a sealing strip cutting device, including a base, a fixing frame fixed on the upper surface of the base, and a processing table, wherein the fixing frame is composed of a vertical rod and a horizontal plate, a first telescopic cylinder is fixed on the lower surface of the horizontal plate, a fixing plate is fixed on the output end of the first telescopic cylinder, and a fixing mechanism and a cutting mechanism are provided on the lower surface of the fixing plate; the fixing mechanism includes an electric push rod arranged on the lower surface of the fixing plate, a connecting sleeve fixed on the output end of the electric push rod, a sliding rod movably extending to the outside of the connecting sleeve, and a suction cup fixed on the lower surface of the sliding rod. The sealing strip cutting device starts the electric push rod, so that its output end pushes the connecting sleeve to move, so that the two suction cups are close to or away from each other, thereby adjusting the suction cups, and by adjusting the spacing between the suction cups, it is convenient to fix sealing strips of different widths, thereby achieving the advantage of being convenient to fix sealing strips of different lengths.

[0004] Since the port of the sealing strip is generally at an angle of forty-five degrees, the sealing strip may be stretched during cutting, causing the dovetail angle to increase and become unable to fit with the triangular protrusion at the other end. In addition, the conveying structure of the existing beveling equipment is generally set at the feed point. After the cutting tool is reset, the cut strip is discharged by conveying the strip into the equipment. This method may cause the two sections of the strip to be squeezed and stuck against each other inside the equipment, affecting the normal operation of the equipment. Utility Model Content
