[0002] When the film laminating machine is working, it needs to paste the film on the casing of the mobile phone, MP3 and other electronic products. At this time, the film used is in rolls, and the film is transported to the film laminating machine by the conveying mechanism. The conveying device includes a machine. Shell, two rotatable rollers installed in the casing, one of the two rollers is the driving roller, which is used to connect with the power device to provide power, and the other is the driven roller, which is driven by the driving roller to rotate, driven The roller is hinged on the bracket, and the bracket is fixed on a rotatable shaft, so that the driven roller can rotate around the shaft. When conveying, the film is placed between

Embodiment Construction

[0016] The following descriptions are only preferred embodiments of the present invention, and do not limit the scope of the present invention.

[0017] Examples, see attached Figure 1~3 ; A half gear, including a cylinder 1, the cylinder has a through hole 101; the outer circumference of the cylinder has teeth 102.

[0018] Half of the outer peripheral surface of the cylinder has teeth, and the other half is a smooth surface 103 .

[0019] A pin hole 104 is provided on the smooth surface of the outer peripheral surface of the cylinder, and the pin hole communicates with the through hole.

[0020] There are two pin holes.

[0021] There are chamfers 105 and 106 at both ends of the through hole.

Abstract

The invention discloses a semi-gear which comprises a cylinder which is provided with a through hole. Teeth are arranged at the periphery of the cylinder. Half of the periphery of cylinder is provided with teeth while the other half thereof is a smooth surface. Pin holes are arranged at the smooth surface, the pin holes are communicated with the through hole. Teeth are arranged at the other half of periphery of the cylinder, so that a transmission shaft can be fixed at any position within the scope of 180 degrees. With the function of the transmission shaft, rotation positions of an eccentric wheel can be adjusted so as to adjust clamp force of two roller wheels.

Description

Technical field: [0001] The invention relates to the field of film laminating machine series, and more specifically relates to a half gear of a tensioning conveying device used on a film laminating machine. Background technique: [0002] When the film laminating machine is working, it needs to paste the film on the casing of the mobile phone, MP3 and other electronic products. At this time, the film used is in rolls, and the film is transported to the film laminating machine by the conveying mechanism. The conveying device includes a machine. Shell, two rotatable rollers installed in the casing, one of the two rollers is the driving roller, which is used to connect with the power device to provide power, and the other is the driven roller, which is driven by the driving roller to rotate, driven The roller is hinged on the bracket, and the bracket is fixed on a rotatable shaft, so that the driven roller can rotate around the shaft. When conveying, the film is placed between t...
