For accommodating tow 30 between two teeth adjacent to plate 15, and guiding role is played to tow 30, prevents the disengaging of tow 30 from leading
To wheel 14.
As shown in figures 1 and 3, the side for compressing wheel assembly 20 is provided with threaded hole 113 on the first support 11, the spiral shell
Pit 113 can cooperate with the 4th bolt 27, will compress wheel assembly 20 and the first support 11 is secured together.Specifically, the 4th
Bolt 27 is tightened on threaded hole 113 after passing through the mounting hole 211 on the second support 21, and therefore by the first support 11 and the
Two supports 21 are secured together to.Alternatively, those skilled in the art also can according to need, by the first support 11 and the second support 21
It is made for the support of an entirety.
As shown in Figure 1, Figure 2 and shown in Fig. 5, compressing wheel assembly 20 mainly includes the second support 21, the second shaft 22, multiple rotations
Seat 23, multiple contact rollers 24, multiple bearings 25 and third shaft 26.
With continued reference to Fig. 1, Fig. 2 and Fig. 5, the both ends of the second shaft 22 are connected with the second support 21 respectively, prevent second
Shaft 22 moves axially and or radially.One end of each rotating seat 23 is pivotally connected to the second shaft 22 respectively
On, the other end of each rotating seat 23 is pivotally coupled to a contact roller 24 respectively.Specifically, each rotating seat 23
The other end be respectively coupled a third shaft 26.Bearing 25 is set in third shaft 26, and contact roller 24 is set in axis
It holds on 25.More specifically, the inner ring of bearing 25 is connected with third shaft 26, the outer ring of bearing 25 be connected with contact roller 24 or
It is made into integration.In a preferred embodiment of the invention, bearing 25 is plain bearing, so that contact roller 24 can be freely rotated.
Or those skilled in the art also can according to need, and bearing 25 is arranged to unilateral bearing, and make its rotation direction and unidirectional
The rotation direction of bearing 13 is opposite.
As shown in Figure 1 and Figure 5, mounting hole 211 is provided on the second support 21.It is right in the second support 21 and the first support 11
After standard, the 4th bolt 27 can pass through mounting hole 211 and be threadedly coupled to together with the threaded hole 113 on the first support 11,
To which the second support 21 and the first support 11 are secured together to.Or skilled person also can according to need, and make first
Support 11 and the second support 21 are made into integration.
As shown in Figure 1 and Figure 5, in the case where the first support 11 and the second support 21 are assembled together, with the second support
21 each the 5th bolt 28 (specially the 5th one end of bolt 28 far from nut) being threadedly coupled hold out against a rotation respectively
Swivel base 23, to be respectively clamped into each contact roller 24 in a groove 141 and the bottom surface of compressed grooves 141.Directive wheel
14 and contact roller 24 by therefore clamp tow 30.Wherein, each the 5th bolt 28 can individually adjust to make different
Contact roller 24 can force tight directive wheel 14 with different.
Although not showing that in figure, in a preferred embodiment of the invention, contact roller 24 is using the tool such as polyurethane
Flexible material is made, and is coated on the outer ring of bearing 25.To improve the frictional force between contact roller 24 and tow 30, prevent
Occur pumpback phenomenon when only tow 30 is cut off, while can also prevent 24 hardness of contact roller is excessive to cut when contacting with directive wheel 14
Fracture of wire beam 30.In addition, those skilled in the art can also be as needed, directive wheel 14 is also made of elastic material.Alternatively,
Only directive wheel 14 is made of elastic material.It will be appreciated to those of skill in the art that in order to avoid the waste of material, this
Field technical staff also can according to need, and circumferentially upper flexible situation is arranged in directive wheel 14 and/or contact roller 24.
In other words, only the structure in 24 circumferential direction of directive wheel 14 and/or contact roller is made of elastic material.
It should be noted that directive wheel 14 of the invention, rotating seat 23, contact roller 24 and the 5th bolt 28 quantity not only
It is limited to four shown in the drawings, in the case where matching each other, can also be any other multiple, for example, two, three
A, five, eight etc..
The application method of tow guiding device of the invention is briefly described below with reference to Fig. 1 to Fig. 3.
When tow guiding device wears silk (tow 30), under first compression wheel assembly 20 is dismantled from guide wheel assemblies 10
Come, tow 30 is then made to sequentially pass through pore structure 112 and comb-tooth-type guide plate 15, and is embedded in tow 30 in groove 141.Later
Wheel assembly 20 will be compressed again and is installed in guide wheel assemblies 10 and adjusts the 5th bolt 28, to make 24 compressed grooves of contact roller
Tow 30 in 141.When tow 30 is conveyed, directive wheel 14 and contact roller 24 are rotated synchronously.When tow 30 is cut off, lead
To wheel 14 and contact roller 24 under the action of unilateral bearing 13, holds tow 30 and be maintained at current location.
Therefore, tow guiding device of the invention can make tow 30 be maintained at current state after being cut off, will not
Pumpback phenomenon occurs because of the tensile force of itself.Fluency, precision when ensure that composite material piddler equipment piddler next time
And quality.
In addition, the present invention also provides a kind of composite material piddler equipment comprising above-mentioned tow guiding device.It is preferred that
Ground, tow guiding device is arranged on the piddler head of composite material piddler equipment, and those skilled in the art can be according to need
