Abstract: A laminator with an improved heating structure comprising a machine body, an inlet roller unit, an outlet roller unit and a heating unit, wherein the inlet roller unit, the outlet roller unit and the heating unit are respectively positioned in an internal accommodating space of the machine body, and the heating unit is positioned between the inlet roller unit and the outlet roller group. To carry out lamination, the heating unit is able to directly heat a laminating film, which means directly heating a laminator to avoid waiting for heating, so the aim of improving the utilization efficiency is fulfilled.

Abstract: The present invention discloses a rotary cutter door device for a paper shredder, comprising a guide rod, a guide plate assembly, a rotary bearing, and a cutter door installed above the spindle cutter, wherein the guide plate assembly includes a guide plate and its support, the guide plate is installed on the side wall of the spindle cutter through the guide plate support and can slide horizontally on the guide plate support; a first and a second groove are configured sidelong on the guide plate, the guide rod is mounted in the first groove, the rotary bearing is installed in the second groove and the rotary bearing is fixed with the rotary spindle of the cutter door. When the rotary cutter door device opens the upper cover of the paper shredder, the cutter door is closed and fingers and sundries cannot touch the blades, thus improving security.

Abstract: A single-roller automatic paper feeding mechanism disclosed by the present invention belongs to an office apparatus, comprising a supporting port, a paper feeding mechanism, and two cutters configured on the supporting part, a cover plate connected movably with the supporting part, a paper placing platform configured above the cutter, a sensor configured on the paper placing platform, wherein the paper feeding mechanism is a single roller group formed by connecting several rollers serially; also comprising a paper pressing plate connected with the cover plate, wherein an elastic pressing device is configured between them; also comprising a baffle which is configured on the paper placing platform and connected with it rotatably, wherein a hole capable of accommodating the baffle is configured at the place corresponding to the paper pressing plate surface contacting with the paper placing platform.

Abstract: This invention discloses a laminator with a rolled paper sensing device, which comprises a machine body, a roller unit; at least one actuating element, sensor and guide. The machine body comprises an inlet, an internal accommodating space and an outlet, which are in communication with one another. Within the accommodating space, the roller unit is located which includes upper and lower rollers, and a channel between the upper and lower rollers leads to the inlet and the outlet; the actuating element is installed and positioned between the roller unit and the outlet; the sensor is located and adjacent to the actuating element; and the guide is located and in communication with the channel and the actuating element. Thus, the aim of sensing rolled paper of the laminator to avoid damaging the laminator and improve the utilization efficiency of the laminator is fulfilled.
