The cantilevered mounting structure form of the carry-over pinch rolls of existing plastic flat fiber drawing and shaping device is as shown in Figure 2: carry-over pinch rolls 2 comprise roller 21, mandrel 22, mandrel support tube 23; The mandrel support tube is fixed on bearing body 3 sides through bolt 4; Mandrel support tube two ends are respectively equipped with bearing A, bearing B, and mandrel 22 is supported on the mandrel support tube 23 through bearing A, bearing B; Mandrel 22 is fixed together through contiguous block 24 with roller 21; One end of mandrel 22 stretches into bearing body 3, and whole mandrel 22 can rotate, and is provided with in bearing body 3 inside to drive the driving mechanism that mandrel rotates; The external diameter of mandrel support tube 23 is less than roller 21 internal diameters, and whole mandrel support tube 23 is hidden and is located in roller 21 inner chambers.During work, rotate, drive roller 21 by mandrel 22 through contiguous block 24 and rotate synchronously by being installed in the inner drive mechanism mandrel of bearing body 22.
There is following problem in the mounting structure form of existing plastic flat fiber drawing and shaping device: 1, complex structure, fabrication and installation difficulty; 2, in the running, mandrel 22 eccentric error occurs easily with roller 21, and error can be accumulated, amplified; Make roller 21 more large eccentricity occur, cause and rock, specifically; If mandrel position off-centre occurs at the A point, it is eccentric greatly that the CD section is occurred; And mandrel CD fragment position is eccentric, can cause roller 21 eccentric error to occur again, and this eccentric error can be amplified at the right-hand member (K end) of roller more at double; 3, the weight of roller 21 is pressed in the CD section of mandrel through contiguous block 24; CD section by mandrel is delivered on the two bearings again; And the CD fragment position of mandrel drops on outside bearing A and the bearing B line, so bearing A and bearing B be the forms of encorbelmenting to the supporting form of roller 21, and stress form is complicated; And shaft strength is big, and is easy to wear.
In a word, the carry-over pinch rolls complex structure of existing drawing and shaping device, the fabrication and installation difficulty requires height to making precision and the material that node is installed, and shaft strength is big, and eccentric error can be accumulated step by step, amplified, and the roller shaking amplitude is big.For above-mentioned these problems; People once attempted to improve always, but failed to overcome these problems always, and this mainly is owing to receive the restriction of many factors; These limiting factors comprise many-side; For example: 1, owing to there is a leverage, two strong point A of mandrel and the distance between the B must be enough greatly, otherwise bearing A, bearing B will bear great role power; 2, bearing A, bearing B and mandrel support tube must be assembled into one in advance; Therefore two strong point A, the B of mandrel or can only all be arranged on bearing body inside (promptly all being arranged in Fig. 2 MN line right side), or can only all be arranged on bearing body outside (promptly all being arranged in Fig. 2 MN line left side); And the width NP of bearing body, promptly is arranged on outside also Tibetan of bearing body to be located in the roller inner chamber so bearing A, bearing B and mandrel support tube just can only be assemblied in MN line left side among Fig. 2 less than spacing between bearing A and the B bearing; 3,,, make the length of CD section very short so can only tie up the length (length of CD section is exactly two length that support between the end points of roller) of CD section because spacing must be enough big between bearing A and the B bearing; 4, because two length (CD segment length) that support between the end points of roller are short, so the off-centre that C point or D are ordered can cause that the off-centre about roller 4-5 is doubly rocked.
Summary of the invention
The objective of the invention is to be directed against the above-mentioned deficiency of prior art and a kind of plastic flat fiber drawing and shaping device is provided, it is simple in structure, and assembling is easy, and shaft strength is little, and roller is reliable in operation process, is difficult for rocking.
Be to realize that above-mentioned purpose, plastic flat fiber drawing and shaping device of the present invention comprise bearing body, some carry-over pinch rolls, drive the motor of carry-over pinch rolls, every carry-over pinch rolls comprise roller and mandrel; One end of every mandrel is positioned at bearing body inside and the other end stretches out the bearing body side; Each roller is installed in a side of bearing body; Its main feature is that said each mandrel is fixedly connected with bearing body, and each roller utilizes at least that two bearings is assemblied on the corresponding mandrel rotationally; Every roller also is connected with belt rim at the end near bearing body; Motor is connected with main pulley, and main pulley drives the belt rim of each roller through driving belt.
Be preferably, also be provided with driven pulley, be provided with first driving belt between main pulley and the driven pulley, be provided with second driving belt between the belt rim of driven pulley and each roller.
Compare with the conventional plastic flat fiber drawing and shaping device, the present invention has the following advantages and effect:
1, the mandrel in the traditional structure is supported on the two bearings rotationally, and mandrel of the present invention is fixedly mounted on the bearing body, so mandrel is not firmly, can rock, and has reduced a factor that possibly cause that roller rocks.
2, in traditional structure; Two strong points of mandrel, two Zhi Duandian of roller all are positioned at the outside the same side of bearing body; Each strong point position distribution in the axial direction is more crowded, and the distance between two strong points of mandrel is short, and the distance between two strong points of roller is also short; Therefore eccentric when certain strong point appearance, the offset of roller can be amplified at double.
And among the present invention; The support zone of mandrel is positioned at (two-end-point of mandrel support zone is positioned at bearing body inside) on the bearing body, and two support end points of roller are positioned at outside the bearing body, and it is looser that each supports end points distance in the axial direction; Distance is bigger between the two-end-point of mandrel support zone; Distance is also bigger between two strong points of roller, even therefore eccentric when certain support end point appearance, the multiple that the offset of whole roller is exaggerated is less.
3, shaft strength of the present invention is little than traditional structure, this be because: a, bearing of the present invention only need be born the weight of roller, and need not bear the weight of mandrel; The center of gravity of roller is between two bearings among b, the present invention, so two bearings of the present invention are not the forms of encorbelmenting to the supporting form of roller, and stress form is more favourable, and is stressed little.The present invention is because shaft strength is little, so bearing wear is little, and it is quiet steady more to help the roller running.
4, the present invention is simple in structure, and fabrication and installation are easy, and shaft strength is little, and is lower to making precision and material requirement that node is installed, and eccentric error can be by accumulation, amplification in the operation process, and roller operation process shaking amplitude is little.
