[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution:

[0026] See also Figure 1 to Figure 2A guide device for conveying PVC antistatic coiled materials comprises an assembly frame 1, the rear end of the assembly frame 1 is rotatably connected to a conveying roller 2, the front end of the assembly frame 1 is provided with a receiving roller 3, the top of the assembly frame 1 is fixed with a mounting frame 4, and a tensioning mechanism 5 is arranged above the mounting frame 4; the tensioning mechanism 5 comprises a driving motor 501, the driving motor 501 is embedded in one side of the top of the mounting frame 4, the power output end of the driving motor 501 is connected to a threaded screw 502, the threaded screw 502 penetrates into the outer wall of one end of the mounting frame 4 and is slidably connected to a slider 503, and the outer wall of the slider 503 A tensioning roller 504 is provided on one side, and a rotating shaft 505 is embedded in the axially relative outer walls of the two sliders 503. One end of the rotating shaft 505 is rotatably connected to a fixed shell 506. Pressing blocks 507 are provided at the top and bottom of the fixed shell 506. A first damping spring 508 is embedded in the top of the fixed shell 506. The slider 503 is threadedly connected to the threaded screw 502. A sliding structure is formed between the slider 503 and the mounting frame 4. A limiting groove 6 is provided on the outer wall of the mounting frame 4 corresponding to the position of the slider 503. The end of the tensioning roller 504 away from the slider 503 is connected to the limiting block 7.

[0027] By adopting the above technical scheme, the material is first transported by the conveying rollers 2 and the receiving rollers 3 at the front and rear ends of the assembly frame 1. During the conveying process, the material is attached to the outer wall of the tensioning roller 504. The driving motor 501 drives the threaded screw 502, thereby pushing the slider 503 to slide along the mounting frame 4, and cooperates with the limit block 7 to allow the tensioning roller 504 to rise and fall within the range of the mounting frame 4, so as to tension the material to avoid looseness. The slider 503 slides stably through the limit groove 6, and at the same time, the fixed shell 506 is rotatably connected to the slider 503 through the rotating shaft 505, and adjusts its position with the tensioning roller 504, allowing the first damping spring 508 to elastically push the pressing block 507, and the material is pressed against the pressing block 507 below to flatten it to avoid wrinkles. At the same time, the rotating shaft 505 facilitates the fixed shell 506 to adjust its angle following the adjustment height of the tensioning roller 504, so that the pressing block 507 can always fit the material.

[0028] Specifically, Figure 1 , Figure 3 and Figure 4As shown, a limiting mechanism 8 is provided inside the tensioning roller 504, and the limiting mechanism 8 includes a moving plate 801, and the moving plate 801 is slidably connected to the outside of the tensioning roller 504. The moving plate 801 penetrates into the axial direction of the tensioning roller 504 and is fixed with a moving block 802. A bidirectional threaded rod 803 penetrates inside the moving block 802, and one end of the bidirectional threaded rod 803 penetrates into the limiting block 7 and is connected to a rotating motor 804. The moving plate 801 forms a sliding connection between the moving block 802 and the tensioning roller 504. Structure, the moving block 802 is threadedly connected with the bidirectional threaded rod 803, a second damping spring 9 is embedded on one side of the driving motor 501 at the top of the mounting frame 4, and the second damping spring 9 is connected to a lower pressure plate 10 at one end passing through the mounting frame 4, and a mounting seat 11 is fixed to the bottom end of the lower pressure plate 10, and a lower pressure roller 12 is rotatably connected to the lower side of the mounting seat 11. The lower pressure plate 10 forms an elastic structure with the mounting frame 4 through the second damping spring 9, and the lower pressure plate 10 is detachably connected to the mounting seat 11 by bolts.

[0029] By adopting the above technical solution, the bidirectional threaded rod 803 is driven by rotating the motor 804, thereby pushing the moving block 802 to slide stably along the inside of the tensioning roller 504, thereby driving the moving plate 801 to limit the material from both sides, and adjusting according to the size of the material to avoid deviation during the conveying process. When the tensioning roller 504 rises, the elastic push of the second damping spring 9 allows the lower pressure plate 10 to drive the mounting seat 11, allowing the lower pressure roller 12 to contact the tensioning roller 504 for leveling to avoid wrinkles. The lower pressure roller 12 is shorter than the tensioning roller 504, so as to avoid the situation where the material is short and is limited by the moving plate 801.

[0030] Working principle: The assembly frame 1 conveys the material through the conveying roller 2 and the receiving roller 3. At the same time, the material is attached to the tensioning roller 504. The driving motor 501 works to drive the threaded screw 502 to rotate, so that the slider 503 and the limit block 7 slide along the mounting frame 4, driving the tensioning roller 504 to tighten the material to prevent it from being loose. At the same time, the slider 503 slides stably through the limit groove 6, and is connected to the fixed shell 506 through the rotating shaft 505, so that the two pressing blocks 507 can be adjusted to follow the angle of the material. Flattening, through the first damping spring 508 to avoid excessive flattening affecting transportation, the rotating motor 804 embedded in the limit block 7 drives the bidirectional threaded rod 803, and the moving block 802 drives the moving plate 801 to move, so as to adjust according to the width of the material to avoid deviation in the conveying process. When the tensioning roller 504 rises, it is pressed down by the lower pressure roller 12 to avoid ups and downs. The elastic push of the second damping spring 9 and the lower pressure plate 10 allows the mounting seat 11 to push the lower pressure roller 12 to elastically press to avoid excessive pressing affecting transportation.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
