Description
Technical field
The invention belongs to 3D printing technique field, it is related to a kind of 3D printer structure with belt stretcher.
Background technology
With the development in epoch, 3D printer is increasingly known, and is that daily life work provides
Very big help, especially makes in exemplar trial-production and 3D Original model, the complex-curved forming ability performance of 3D printer
From most cause, current 3D printer divides according to accuracy class mainly technical grade and two kinds of civil to the tinkling of pieces of jade, and 3D printer belongs to
High-accuracy mechanical, as long as the instrument and equipment of high precision is required to equipment user of service and concentrates one's attention on to maintain, patient debugging, at present on the market
Conventional 3D printer power transmit on the overwhelming majority all can by the way of driving stepper motor Timing Belt, this mode excellent
Point be transmission efficiency high it is easy to control, compact conformation, take up room little.Adopt in slide block and the fixation of Timing Belt and be screwed
The mode of pressing plate.
Analyze the above-mentioned prior art referring to have the following disadvantages, i.e. the technical problem to be solved：
With the prolongation of use time, Timing Belt can fluff, and inconsistent phenomenon in 3D printer, and printer on the market is in tensioning
Pressing plate can only be unclamped during Timing Belt, pull up Timing Belt, because synchronous belt teeth is it is desirable to be pulled along first to take off belt
Open and put back to again, Timing Belt is placed on inside machine outer cover plate, unclamp to put back to again and tighten, very difficult in operation, and often because
When tightly not crossing section for drawing, belt shake allowance ratio does not have before tensioning also greatly.
