Abstract
The invention discloses a semi-gear tension conveying device comprising a shell. A driven roll, a driving roll and a transmission shaft are mounted in the shell; a transmission belt pulley is fixed at the end of the driving roll, two eccentric wheels are fixed on the transmission shaft; the two eccentric wheels can contact to the driven roll with the rolling of the transmission shaft, and allows the driven roll and the driving roll to be a compaction state; a semi-gear with a semi-tooth on the outer circumferential surface is also fixed on the transmission shaft; the shell is also provided with a rotating shaft, a semi-gear clamping stem is mounted on the rotating shaft in a clearance fit way, a protrusion capable of being inserted into the tooth of the semi-gear is arranged at the front end of the semi-gear clamping stem; and the upper surface of the protrusion is an inclined surface. The tension conveying device disclosed by the invention not only can be adjusted in the tension force, but also can keep the position in the use process without loosing phenomenon.
Description
Technical field:
Used laminator when the present invention relates to electronic product pad pastings such as mobile phone, MP3 relates to the tension conveying device that uses on a kind of laminator in particular.
Background technology:
Laminator is in work, film need to be attached to mobile phone, on the shell of the electronic products such as MP3, this time, used film all was rolling, by conveying mechanism film is carried up for laminator, feedway comprises a casing, two rotating cylinders that are installed in the casing, one is drive roll in two cylinders, be used for being connected with engine installation, power is provided, another is driven cylinder, by drive roll with rotation, driven cylinder is hinged on the support, and support is fixed on the rotary axle, so that driven cylinder can rotate around axle, film to be placed in the middle of two cylinders when carrying, utilizing two cylinders that film is clamped back roll rotates, the drive film moves forward, and the size of the power of two rotary drum clamping films is to need to adjust, gripping power is excessive, film can be pressed from both sides badly, and gripping power is too small, then cannot carry out the conveying of film, fixing device is arranged on feedway, generally all is a transmission shaft, and the above is with two eccentric wheel, utilize eccentric center principle to realize extruding to flower wheel, provide gripping power, but fixing device is when providing tensile force like this, stable not, can become flexible along with the reasons such as vibration produce, so that the tensile force that acts on the driven cylinder changes.
Summary of the invention:
The purpose of this invention is to provide a kind of half gear tensioning feedway, it can be simply, fast speed is adjusted tensile force and can in use kept position, the phenomenon that can not become flexible again.
Technology solution of the present invention is as follows:
Half gear tensioning feedway comprises casing, and return idler, driving roller and transmission shaft are installed in the casing, and the end of described driving roller is fixed with a drive pulley, is fixed with two eccentric wheel on the described transmission shaft; It is characterized in that: described two eccentric wheel be along with the rotation of transmission shaft can contact return idler, and make return idler and driving roller be impaction state; Also fix one and half gears on the described transmission shaft, have on the outer circumference surface of half gear on half outer circumference surface with teeth; Described casing also has a rotating shaft, in this rotating shaft free-running fit half gear card handle is installed, the front end of this half gear card handle has a protrusion that can insert in the teeth of described half gear, this protrusion upper surface has a dip plane.
Described half gear tensioning feedway, the end of described transmission shaft is fixed with a turning handle.
Described half gear tensioning feedway, described half gear is fixed on the described transmission shaft by two pins.
Beneficial effect of the present invention is:
Tension conveying device of the present invention can either can in use keep position, the phenomenon that can not become flexible again by tension adjusting; The front end of half gear card handle has a protrusion, the upper surface of protrusion has a dip plane, the teeth on half gear can be blocked in this dip plane, therefore be called half gear card handle, the card handle is installed in the fixing rotating shaft of another root, because hole and rotating shaft on the card handle are free-running fits, the card handle can pivot for stirring by the people, discharges half gear, and two eccentric wheel are installed at the transmission shaft two ends, the Main Function of transmission shaft, be the eccentric position of installing for the actuating spindle two ends, when eccentric wheel rotates to two roller compressions, the teeth on half gear will be blocked by the protrusion of card handle front end, transmission shaft is fixed, thereby has fixed eccentric position.On the half circumference of gear surface, the geared surface area is larger, and the angle adjustable scope of transmission shaft is just larger, and the number of teeth is carried manyly on the equal area, and the angle precision of adjusting S. A. is just higher.This can be determined according to actual conditions, half is arranged on the present invention's half circumference of gear is the dentation that teeth are arranged, make transmission shaft can be fixed on the interior any angular position of 180 degree scopes, utilize this effect of transmission shaft, come the position of rotation of eccentric adjustment wheel, thereby reach the effect of the gripping power of regulating two rollers.
When transmission shaft is blocked handle along a direction rotation to first tooth and is blocked, because card handle structure design, transmission shaft can continue along direction rotation, but can not turn round by reversing sense, after transmission shaft is stuck, continue again rotation, will increase the gripping power of two rollers, when rotating to last tooth and be stuck, gripping power is maximum.If when the card handle needs when blocking gear to discharge gear, then will block the other end of handle to pressing down, just can discharge transmission shaft, allow the transmission shaft state that affranchises, two rollers also the while released.
Description of drawings:
The present invention is described further below in conjunction with accompanying drawing:
Fig. 1 is structural representation of the present invention;
Fig. 2 is schematic perspective view of the present invention;
Fig. 3 is another schematic perspective view of the present invention;
Fig. 4 is the structural representation of the present invention's half gear;
Fig. 5 is the structural representation of the present invention's half gear card handle.
The specific embodiment:
The following stated is preferred embodiment of the present invention only, is not that scope of the present invention is limited.
Embodiment sees accompanying drawing 1～5; Half gear tensioning feedway, comprise casing 1, return idler 2, driving roller 3 and transmission shaft 4 are installed in the casing, the end of described driving roller is fixed with a drive pulley 5, be fixed with two eccentric wheel 6 on the described transmission shaft, described two eccentric wheel be along with the rotation of transmission shaft can contact return idler, and make return idler and driving roller be impaction state; Also fixing on the described transmission shaft on the outer circumference surface of one and half gears, 7, half gears has on half outer circumference surface with teeth 7a; Described casing also has a rotating shaft 8, free-running fit is equipped with half gear card handle 9 in this rotating shaft 8, the size in gap can freely be rotated in rotating shaft with half gear card handle and is advisable, the front end of this half gear card handle has a protrusion 9a that can insert in the teeth 7a of described half gear, and this protrusion upper surface has a dip plane 9b.This dip plane has guaranteed that half gear can only be to a direction rotation, and can not turn round, because rotating the time, the base plane that can be highlighted the 9a of section is blocked.
The end of described transmission shaft is fixed with a turning handle 10.
Described half gear is fixed on the described transmission shaft by two pins 11.Two and half gears have two pin-and-holes, and two pin one ends are inserted in these two pin-and-holes, and the other end is fixed on the transmission shaft, so just half gear has been fixed on the transmission shaft.
