Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, and more specifically, to a tape punching device. Background Art

[0002] The plastic tape substrate is difficult to tear when used, and auxiliary tools are needed to cut the tape, which is not only inconvenient to use, but also the cross section of the tape is not neat, affecting the appearance. Therefore, tapes with through holes and equipment for punching holes in tapes have appeared on the market.

[0003] The patent with announcement number CN2383821Y discloses a tape punching machine, which includes a frame, on which a feeding roller, a product roller, a rubber roller, and a licker-in roller are installed. The licker-in roller is equipped with a heating device, and a power device installed under the frame is connected to a transmission mechanism outside the frame. The transmission mechanism connects the rubber roller and the licker-in roller. The surface of the licker-in roller is evenly covered with needles, and the rubber roller and the licker-in roller are pressed against each other.

[0004] Although the above patent has a simple structure and is easy to operate, the output roller and the feeding roller are both arranged below the licker-in roller, so that the tape forms a triangular running route. Therefore, it is easy to cause repeated punctures of the tape close to the licker-in roller, resulting in poorly punched tape. Moreover, the mutual movement between the rubber roller and the licker-in roller drives the tape to do feeding movement, which easily deforms the holes on the tape and affects the use experience of the tape. Therefore, it is necessary to improve the above tape punching machine. Utility Model Content
