Abstract
The utility model discloses an eccentric wheel tensioning device which comprises a transmission shaft, wherein two eccentric wheels are fixed on the transmission shaft, and a handle is fixed at one end part of the transmission shaft. The eccentric wheel tensioning device has a simple structure, and the tensile force can be adjusted by only fixing the two eccentric wheels on the transmission shaft.
Description
Technical field:
Used laminator when the utility model relates to electronic product pad pastings such as mobile phone, MP3 relates to the eccentric wheel tightening device that uses on a kind of laminator in particular.
Background technology:
Laminator is in work, film need be attached on the electronic product shell such as mobile phone, MP3, this time, used film all was a rolling, carry up worker's laminator to use film by conveying mechanism, be film to be placed in the middle of two cylinders when carrying, utilize two cylinders that film is clamped back roll and rotate, drive film and move forward, and the size of the power of two cylinder clamping films is to need to adjust, and will use tightening device this time.
The utility model content:
The purpose of this utility model provides a kind of eccentric wheel tightening device of simple in structure, cheap, processing ease.
Technology solution of the present utility model is as follows:
The eccentric wheel tightening device comprises a transmission shaft, is fixed with two eccentric wheel on the described transmission shaft.
Described eccentric wheel tightening device, an end of described transmission shaft is fixed with a handle.
Described eccentric wheel tightening device has pin-and-hole on described two eccentric wheel, and the connecting pin that eccentric wheel and described transmission shaft are fixed together is arranged in the described pin-and-hole.
Described eccentric wheel tightening device, described connecting pin are round pin.
The utility model beneficial effect is:
The utility model is simple in structure, has just fixed two eccentric wheel on transmission shaft, has just realized regulating the effect of tensile force.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an eccentric schematic diagram of the present utility model;
Schematic diagram when Fig. 3 is eccentric wheel work of the present utility model.
The specific embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1～3; The eccentric wheel tightening device comprises a transmission shaft 1, is fixed with two eccentric wheel 2 on the described transmission shaft.
An end of described transmission shaft 1 is fixed with a handle 3.
On described two eccentric wheel 2 pin-and-hole 201 is arranged, the connecting pin 4 that eccentric wheel and described transmission shaft are fixed together is arranged in the described pin-and-hole.
Described connecting pin 4 is a round pin.
Principle of work: eccentric transmission shaft is installed on the adapter plate, can not become with respect to the adapter plate position, by handle 3 control rotations, when eccentric wheel 2 pivots, to change with rotation with the distance at roller 5 surperficial contacted eccentric wheel peripheries and camshaft center, the shaft core position of roller 5 will change accordingly, as accompanying drawing 2, shown in 3, when with the distance at roller 5 surperficial contacted eccentric wheel peripheries and camshaft center when maximum, two rollers 5,6 clamp, opposite, when with the distance at roller 5 surperficial contacted eccentric wheel peripheries and camshaft center hour, two rollers 5,6 separately.
