Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] refer to Figure 1-2 As shown, the present invention provides an automated precision positioning and conveying device for PP prepreg, comprising: a spraying die head 4, a heating roller 5, and a winding mechanism 6 arranged sequentially. The spraying die head 4 is also provided with a positioning mechanism for positioning the PP prepreg on the side opposite to the heating roller 5. The positioning mechanism includes a rectangular mounting frame 1, a guide roller 3, and two elongated spring pieces 14. The guide roller 3 is rotatably mounted on the rectangular mounting frame 1. The top ends of the two spring pieces 14 are mounted on the top of the rectangular mounting frame 1, and the bottom ends of the two spring pieces 14 fall onto the top of both ends of the guide roller 3. A positioning area for positioning the PP prepreg is formed between the two spring pieces 14.

[0026] The spraying die 4, heating roller 5, winding mechanism 6 and positioning mechanism provided by this utility model are all existing technologies. The core components of these components are not involved in this utility model and will not be described in detail. Before the PP prepreg enters the spraying die 4, it is positioned by two spring sheets 14 to ensure that the PP prepreg enters the spraying die 4 stably.

[0027] In this utility model, combined with Figure 2 As shown, the rectangular mounting frame 1 of this embodiment is also provided with a moving mechanism for driving the guide roller 3 to move axially. The moving mechanism causes the guide roller 3 to move the PP prepreg material between the two spring sheets 14 based on the movement.

[0028] Combination Figure 2 As shown, the moving mechanism includes a U-shaped mounting base 11 and a driving component. The driving component is mounted side by side below the guide roller 3. The guide roller 3 is rotatably mounted in the U-shaped mounting base 11. The driving component is used to drive the U-shaped mounting base 11 to move along the axial direction of the guide roller 3.

[0029] As described above, when using the moving mechanism provided by this utility model, the guide roller 3 is rotatably mounted on the U-shaped mounting base 11. When the driving component drives the U-shaped mounting base 11 to move axially, it drives the guide roller 3 to move axially, thereby driving the PP prepreg material to adjust its position between the two spring sheets 14.

[0030] Furthermore, in order to drive the U-shaped mounting base 11 to move, refer to Figure 3 As shown, the driving component includes a screw 8, a motor 9, and a screw seat 7. The screw seat 7 is welded to the bottom of the U-shaped mounting base 11. The screw 8 is rotatably mounted in the rectangular mounting bracket 1, and the screw seat 7 is screwed onto the screw 8. One end of the screw 8 is mounted on the output end of the motor 9. The motor 9 drives the screw 8 to rotate, thereby moving the screw seat 7, which in turn drives the guide roller 3 on the U-shaped mounting base 11 to move axially.

[0031] Furthermore, to facilitate the rotation of the guide roller 3 on the U-shaped mounting base 11, refer to Figure 3 and Figure 5 As shown, bushings 10 are provided on the axis at both ends of the guide roller 3, and a bearing body 19 is embedded and mounted on the U-shaped mounting base 11 on the outside of each bushing 10. The guide roller 3 is rotatably mounted on the U-shaped mounting base 11 through the bushings 10 and the bearing body 19, so that the rotation of the guide roller 3 to convey PP prepreg will not be affected when the U-shaped mounting base 11 moves.

[0032] Furthermore, to facilitate axial guidance of guide roller 3, refer to Figure 2-3 As shown, the rectangular mounting frame 1 is also provided with a crossbar 2 for axially guiding the guide roller 3. The guide roller 3 has a through hole 18 that passes through two bushings 10, and the crossbar 2 is disposed through the through hole 18. The guide roller 3 is positioned and installed in the predetermined installation position of the rectangular mounting frame 1 by means of the crossbar 2. The guide roller 3 is rotatably mounted on the crossbar 2 through the through hole 18, so that when the moving mechanism drives the guide roller 3 to move, the guide roller 3 can only move in the axial direction through the crossbar 2.

[0033] In this utility model, combined with Figure 2-3 As shown, in this embodiment, each of the two spring pieces 14 is provided with an infrared sensor 12 for offset detection on the opposite side. The tail ends of the two infrared sensors 12 are mounted on the inner wall of the rectangular mounting bracket 1. Each spring piece 14 is provided with an identification block 13 for infrared identification at a higher position on the side closer to the infrared sensor 12.

[0034] As described above, by using the infrared sensor 12 and the identification block 13 provided by this utility model, the position of the spring sheet 14 can be detected. When the PP prepreg comes into contact with the spring sheet 14, the spring sheet 14 bends and deforms. At this time, the infrared sensor 12 detects that the position of the spring sheet 14 has been displaced. The infrared sensor 12 sends an electrical signal to the moving mechanism, causing the moving mechanism to drive the PP prepreg to move in the opposite direction to the bending of the spring sheet 14, so that the PP prepreg is between the two spring sheets 14.

[0035] In this utility model, combined with Figure 3-4 As shown, the top of the rectangular mounting frame 1 in this embodiment is also provided with a moving groove 17 along the axial direction of the guide roller 3. The top of each of the two spring pieces 14 is provided with a moving block 15 that moves in the moving groove 17. Each moving block 15 is provided with a fastening bolt 16 that runs from the outside to the inside, and one end of the fastening bolt 16 abuts in the moving groove 17.

[0036] As described above, by using the movable groove 17 and movable block 15 provided by this utility model, the spring piece 14 can be moved on the rectangular mounting frame 1, thereby adjusting the gap between the two spring pieces 14. After the position adjustment is completed, tighten the fastening bolt 16 to fix the movable block 15 in the movable groove 17, so as to prevent the spring piece 14 from being displaced during use, thereby making the equipment suitable for PP prepregs of different widths.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
