Be provided with the fluting of vertical direction on the said support with the corresponding position of the projecting shaft of floral axis.
Said line shaft is 4.
Said Metallic rod is the 4-12 root.
Said transmission mechanism is to be packed in driving wheel on the variable-frequency motor output shaft, to be packed in the driven pulley on the line shaft nearby and to connect the conveyer belt of driving wheel and driven pulley.
Said synchronous drive mechanism is the chain that is packed in the sprocket wheel on each line shaft and connects each sprocket wheel, and the number of teeth of said each sprocket wheel equates.
Advantage and good effect that the present invention has are:
Through adopting the above-mentioned thin layer processing shape that constitutes by motor, power transmission shaft, slider-crank mechanism and floral axis; Can the large-tow carbon fiber alternatively up and down be wrapped on the floral axis; Behind electric motor starting, floral axis drives big tow and does the alternatively up and down vibration, and the big tow that moves is by thin layerization.

The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1-3; A kind of large-tow carbon fiber thin layer treating apparatus; Comprise frame, be installed in the frame lower end variable-frequency motor 2, through shaft stool 3 be installed in parallel in several line shafts 4 on the frame, be located at the frame top with line shaft several floral axis one to one; Floral axis is made up of the disk 5-1 at two ends, several Metallic rod 5-2 and the coaxial outer projecting shaft 5-3 of two ends disk that is fixed on that is fixed on the disk of two ends with the circle five equilibrium; Consider that from the production practices angle Metallic rod on the floral axis is advisable with 4-12; Be provided with the slider-crank mechanism that constitutes by crank disc 6, connecting rod 7 and first slide block 8 between above-mentioned line shaft and the floral axis; Concrete; One end of connecting rod is connected with eccentric shaft 6-1 on the crank disc through bearing; At the outer face of first slide block fixed installation hinge 8-1, the other end of connecting rod is installed on the hinge through bearing, and the size of the offset of eccentric shaft has determined the amplitude of floral axis up-down vibration on the above-mentioned crank disc; The projecting shaft of above-mentioned floral axis is rotatably installed on first slide block through bearing; Be installed with support 9 in said frame upper end, said support is connected through line slideway auxiliary with first slide block, and is concrete; Guide rail 10 in the line slideway auxiliary is fixedly mounted on the support; Second slide block 11 that cooperates with guide rail is fixedly mounted on above-mentioned first slide block, and above-mentioned line slideway auxiliary can be one group, be located at floral axis under; Also can be two groups, symmetry is located at the both sides of floral axis; For reducing the above-mentioned support and first slide block size in vertical direction; Make overall structure compacter; The fluting 12 of vertical direction can be on support be set with the corresponding position of the projecting shaft of floral axis, and when slider-crank mechanism drove the floral axis motion, the projecting shaft of floral axis moved up and down in fluting; Be provided with transmission mechanism between above-mentioned variable-frequency motor and the line shaft nearby; Concrete; This transmission mechanism can be the driving wheel 13 that is fixedly mounted on the variable-frequency motor output shaft, be fixedly mounted on the driven pulley 14 on the line shaft nearby and connect the conveyer belt 15 of driving wheel and driven pulley; Above-mentioned driving wheel and driven pulley can adopt sprocket wheel also can adopt synchronous pulley; Conveyer belt should be chain or synchronous pulley mutually, through adopting above-mentioned drive mechanism, just can variable-frequency motor power be transported on the line shaft nearby; Be provided with synchronous drive mechanism between several above-mentioned line shafts; This synchronous rotating mechanism can adopt gear structure also can adopt the chain gear transmission structure; In the present embodiment; Synchronous drive mechanism is preferably sprocket wheel 16 that is fixedly mounted on each line shaft and the chain 17 that connects each sprocket wheel, and the number of teeth of said each sprocket wheel equates.Above-mentioned frame can be by angle steel or the moulding of square steel assembly welding, and is concrete, comprises the upper, middle and lower-ranking beam structure, and above-mentioned variable-frequency motor is fixedly mounted on the crossbeam 1-1 of lower floor; Shaft stool is fixedly mounted on the crossbeam 1-2 of middle level, and shaft stool is connected through bearing with line shaft; Above-mentioned support 9 is fixedly mounted on the upper strata crossbeam 1-3 of frame.Adopt above-mentioned treating apparatus to realize the thin layerization of large-tow carbon fiber, need large-tow carbon fiber to move ahead and receive up-down vibration in the process, specific to said structure; Promptly under the effect of crank block; The upper and lower alternating movement of adjacent floral axis, so the quantity of floral axis is at least 2, considers from cost and practice effect two aspects that the thin layer makeup is put; The quantity of floral axis is preferably 4, with floral axis one to one line shaft also should be 4 mutually.
The course of work of the present invention is:
Before starter motor, at first adjust each line shaft; The eccentric shaft that is fixed on the crank disc on each line shaft all is positioned on the same horizontal plane; This moment, the axle center of each floral axis also was positioned on the same horizontal plane, large-tow carbon fiber 18 alternatively up and down was wrapped on the Metallic rod of floral axis, after guaranteeing electric motor starting; Adjacent floral axis up-down alternative motion, the phase difference of the eccentric shaft of above-mentioned adjacent crank disc are 180 °.After carrying out above-mentioned preparation, start variable-frequency motor, the running of driven by motor line shaft, each line shaft drives the up-down vibration that floral axis is done certain frequency through corresponding slider-crank mechanism, mobile carbon fiber under the alternatively up and down vibration of adjacent floral axis by thin layerization.
