The invention discloses a laminating device for enhancing laminating precision of a cover film. The laminating device comprises a base. A plurality of first grooves are formed in the base; the plurality of first grooves internally sleeve push rod motors; an output shaft of each of the push rod motors is welded to a horizontally arranged layer board; fixed rods are welded to two sides of the layer board; slide blocks are welded to one ends, far from each other, are welded to the two fixed rods; supporting plates vertically connected to the top of the base are mounted on two sides of the layer board; first chutes are formed in one sides, close to each other, of the two supporting plates along the height direction thereof, and the slide blocks are slidably mounted in the first chutes; two second grooves formed in the supporting plates are formed above the two first chutes; and four second grooves internally sleeve springs. The laminating device disclosed by the invention is novel in design and convenient to operate. As the positions of an object and a film are fixed, the laminating precision is improved; moreover, air between the film and the object is discharged by means of a compression roller, so that bubbles are prevented from being generated, and the attractiveness of the cover film is improved.

The invention discloses a cable cutting device, which comprises a box body with an inner cavity. The inner cavity is provided with a cutting mechanism, multiple sets of clamping rollers and two fastening mechanisms. The two fastening mechanisms are located on both sides of the cutting mechanism. A cooling mechanism is provided outside the box to reduce the temperature in the inner cavity; the cut-off mechanism includes an upper cut-off seat at the top of the inner cavity and an upper cut-off seat at the bottom of the inner cavity, and the fastening mechanism includes a fastening upper seat at the top of the inner cavity and an upper cut-off seat at the inner cavity The fastening lower seat on the bottom of the cavity, the upper cut-off seat, the lower cut-off seat and the fastening upper seat are all connected with a drive unit to drive the upper cut-off seat, the lower cut-off seat and the fastening upper seat to and fro; wherein, the clamping roller can clamp Tighten the cable, and the cable can be located between the upper cut-off seat and the lower cut-off seat and between the fastening upper seat and the fastening lower seat. The cable cut by the cable cutting device has an excellent cut surface.
