Abstract
The utility model relates to a belt tension adjuster, arranged on a driving belt of a scanner to adjust the tension state of the driving belt of the scanner. The belt tension adjuster comprises a coil spring for keeping the driving belt in the tension state, a clamping column for fixing the position of the coil spring and a toothed groove for connecting the scanner with the driving belt.
Description
The relevant a kind of belt-tension regulating apparatus of the utility model system refers to the adjusting gear in order to the tension state of adjusting the scanner driving belt especially.
The mode of driving belt tension force is adjusted in the most normal use of current scanline device industry, as shown in Figure 1, a and b are two kinds of common adjustment mode synoptic diagram in the common technology, and figure a is that slide block is rotary-type, comprises: a slide block 52, a spring 51, a belt 53, a carrier 54, a belt pulley 55; Figure b is the rocking arm adjustment type, comprises: one adjusts wheel 63, one spring 51, a belt 53, a belt pulley 55, a rocking arm 62, a carrier 54, one scan device frame 71, a glass 72, a file 73.Slide block rotaring wheel structure among Fig. 1 (a) or rocking arm (b) are adjusted structure, this dual mode all needs slide block or rocking arm, not only easily cause the belt wearing and tearing, belt is also therefore lax, and the drive state that can make driving belt is in course of adjustment and is easy to generate slip, reach the wearing and tearing of movable members, thereby cause the tension state off-design requirement of driving belt, cause drive state bad.Too much because of its spare part in addition, increase manufacturing cost, and reduce the reliability of using.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of and can effectively adjust belt tension, keeps good tension force to avoid producing lax, and has that volume is little, part is few, the belt-tension regulating apparatus of simple shape.
The purpose of this utility model is achieved in that a kind of belt-tension regulating apparatus.System is arranged on the driving belt, it is in order to adjust the transmission tension state of this driving belt, its device comprises: a volute spring, the one end is fixed on the clamping device, and the other end extrudes on this driving belt, so that the drive state of this driving belt is in a specific tensile state, this clamping device wherein, it is one scan assembly frame, it is to be linked on this driving belt, and it comprises: a card post is to be arranged on this scan components frame, it is in order to fix this volute spring, to cause this volute spring can be fixed on this clamping device; One fixation side, its flute profile groove engages with this driving belt, so that this clamping device and this driving belt do not have relative displacement; And a slip side, it is and this driving belt keeps sliding contact, so that this clamping device and this driving belt have relative displacement.
In addition, this driving belt is to return (engagement) belt for the moment.
The utility model belt-tension regulating apparatus, for static state is adjusted mode, on driving belt, set up a volute spring, volute spring extrude in this time return on (engagement) belt, and be fixed in the scan components frame by the card post, return the belt tension of (engagement) belt when adjusting this, make this belt tension remain in specific tension state.This structure is because the slide block of having save in the existing device is taken turns or rocker structure, and adjuster causes the belt wearing and tearing easily when adjusting belt tension thereby improved before, produces the defective of bad belt tension, has simplified the labyrinth of moving parts simultaneously.
Thereby the utility model can effectively be adjusted belt tension, keeps good tension force to avoid producing lax, and it has the effect that volume is little, part is few, simple in structure, thereby can reduce cost, increase functional, the raising industrial competitiveness.
Below in conjunction with drawings and Examples the utility model is further described:
Its a of Fig. 1 and b are two kinds of common adjustment mode synoptic diagram of prior art;
Fig. 2 is the one-piece construction synoptic diagram of the utility model preferred embodiment;
Fig. 3 is the structure action synoptic diagram of the utility model preferred embodiment;
Fig. 4 is the spatial structure combination synoptic diagram of the utility model preferred embodiment.
At first see also Fig. 2, it is the one-piece construction synoptic diagram of the utility model preferred embodiment, return for the moment (engagement) belt (TIMING BELT) 3, one scan assembly frame 2, belt pulley 55, one scan device frame 71, a glass 72, a file 73, it is the synoptic diagram of scanner, and the detailed constitutional diagram of scan components frame 2 among the figure, as shown in Figure 3.
See also Fig. 3 again, it is the utility model preferred embodiment structure action synoptic diagram, Fig. 4 is the spatial structure combination synoptic diagram of the utility model preferred embodiment, by it comprises as can be known among Fig. 3: return (engagement) belt 3, one scan assembly frame 2, a fixation side 21, a slip side 22, a card post 23, a guide rail 4, bearing 41, a direction of motion 8 etc. in a volute spring 1, a period of time.By can know among the figure see volute spring 1 of the present utility model extrude in this time return on the belt 3, and in response to card post 23 and being fixed in the scan components frame 2, return the belt tension of belt 3 when adjusting this, make this belt tension remain in specific tension state.In addition this fixation side 21 is provided with flute profile groove 24, is to return belt 3 to engage binding fully during with this, makes first relative displacement between it.And should slip side 22, be and this time return and be sliding contact between the belt 3, admit of relative displacement, return the belt tension of belt 3 when volute spring 1 can be adjusted.In addition can install charge coupled cell (CCD), camera lens and light source on the scan components frame 2, belt pulley 55 has drive unit to drive it in addition, via the time return belt 3 transmissions, scanner component frame 2 is moved to direction of motion 8 along guide rail 4.(all do not show among the figure.)
Claims (2)
1. an adjusting gear is to be arranged on the driving belt, and it is in order to adjusting the tension state of this driving belt, it is characterized in that its device comprises:
One volute spring, the one end is fixed on the clamping device, and the other end extrudes in this driving belt; And
A described clamping device is an one scan assembly frame, and it is to be fixed on the driver, and it comprises: a card post is to be arranged on this scan components frame, and it is in order to fix this volute spring, to cause this volute spring can be fixed on this clamping device; One fixation side has the flute profile groove, and it is that this driving belt engaging is linked, and causes this clamping device and this driving belt not to have relative displacement; And a slip side, it is and this driving belt keeps sliding contact, causes this clamping device and this driving belt that relative displacement is arranged.
2. adjusting gear as claimed in claim 1 is characterized in that this driving belt, is to return belt for the moment.
