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.

Abstract: A thickness measuring device of a laminating machine includes a mount, a stepper motor, a screw rod, a first contact-activated element, a second contact-activated element, and a microcontroller unit. The stepper motor is coupled to the mount. The screw rod is interlocked with the stepper motor. The first contact-activated element is provided at a position corresponding to and some distance below the screw rod. The second contact-activated element is provided at a position corresponding to and some distance above the screw rod. The microcontroller unit is electrically connected to the stepper motor, the first contact-activated element, and the second contact-activated element so as to provide initialization setting and exercise judgment and control after receiving a thickness measurement. Thus, the thickness of an object to be detected can be conveniently measured.

Abstract: A speed-change transmission mechanism used in a laminator is disclosed to include a plurality of driving gears rotatable with a transmission shaft by a power drive, a driven shaft for rotating two thermal-compression rolls through two meshed driven gears, a plurality of transmission gears respectively mounted on the driven shaft and meshed with the driving gears, and a switching device for selectively controlling rotation of the transmission gears with the driven shaft to further control the speed and torque of the driven shaft.

Abstract: A transmission device of laminating machine comprises a motor interactively driven by an inner gear and a outer gear; an axis for fixing the position of an upper rolling wheel and a lower rolling wheel respectively and passing a document through; a board installed at the inner side of the motor, a positioning hole and a guiding slice disposed on the board, such that the guiding slice is coupled to the external side of the guiding block and the positioning axis is inserted into the positioning hole; a stem extended from the board; and an elastic part installed between the stem and the side board. As long as the stem is pressed downward to rotate the board, the motor and the outer gear will be separated with each other to stop the transmission.

Abstract: A sheet material cutting device includes a base having two brackets, two arms pivotally secured to the brackets, a track secured between the arms and rotated in concert with the arms relative to the brackets, a seat slidably engaged on the track and movable along the track, and a cutter blade secured to the seat. The cutter blade may be forced toward the base in order to forcefully and effectively cut the sheet materials. A board detachably secured to the base, and a plate selectively secured to the board for increasing the surface for supporting the sheet materials.
