[0012] Beneficial effects
[0013] This utility model provides a nonwoven film roll correction device. It has the following beneficial effects: This nonwoven film roll correction device, through the cooperation of the inclined groove, the clamping bolt, and the support, achieves adjustment of the clamping force of the driving roller and the driven roller on the nonwoven film. Thus, when used with nonwoven films of poor strength, the clamping force can be reduced, making it less likely for irreversible deformation and tearing of the nonwoven fabric during correction.

[0018] 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.
[0019] Traditional web-correcting devices have poor adaptability, and the web-correcting force cannot be adjusted according to actual needs. If the web-correcting force is too strong, it may cause irreversible deformation or even tearing of the non-woven film when used on non-woven films with low strength. If the web-correcting force is too weak, it may not be able to meet the web-correcting needs when the non-woven film has a large deviation.
[0020] In view of this, the present invention provides a nonwoven film roll correction device. Through the cooperation between the inclined groove, the clamping bolt and the support, the clamping force of the active roller and the driven roller on the nonwoven film can be adjusted. In this way, when used for nonwoven films with poor strength, the clamping force can be reduced, so that the correction is less likely to cause irreversible deformation and tearing of the nonwoven fabric. When used for nonwoven films with sufficient strength, the clamping force can be appropriately increased, so that the correction effect is better and the nonwoven film roll is wound neatly.
[0021] Depend on Figure 1-3 It is known that the nonwoven fabric roll correction device in this case includes a frame 1, a slide rail 2 is fixedly connected to one side of the top of the frame 1, a slide block 3 is slidably engaged on the upper part of the outer wall of the slide rail 2, an active roller 4 is rotatably connected to the upper part of the inner wall of the slide block 3 through a bearing, a driven roller 6 is provided above the active roller 4, and both ends of the driven roller 6 are installed on the top of the slide block 3 through a limiting device.
[0022] In the specific implementation process, it is worth noting that the frame 1 is the installation carrier of the overall structure, with reserved installation holes and necessary adapter structures, which can be fixed on the non-woven film winding equipment. This allows the non-woven film roll correction device to correct the unwound non-woven film, ensuring neatness after winding. The slide rail 2 and slide block 3 cooperate to allow the active roller 4 and driven roller 6 to move laterally. In this way, the active roller 4 and driven roller 6 are respectively clamped at the bottom and top of the non-woven film. Lateral displacement can adjust the position of the non-woven film and achieve correction.
[0023] In one feasible embodiment, the limiting device includes a support 7, a rod 8, a scale 9, a groove 10, and a clamping bolt 11. The support 7 is rotatably connected to one end of the driven roller 6 via a bearing. The bottom of the support 7 is fixedly connected to the rod 8, which is inserted into the groove at the top of the slide block 3. The surface of the rod 8 is provided with a scale 9. A groove 10 is provided on one side of the outer wall of the rod 8. The inner wall of the groove 10 is fitted with a clamping bolt 11. The clamping bolt 11 extends to the outside of the slide block 3 and is threadedly connected to the slide block 3.
[0024] In the specific implementation process, it is worth noting that the support 7 and the insert rod 8 cooperate to realize the installation of the driven roller 6 and the slide 3. The distance between the driven roller 6 and the driving roller 4 can be adjusted. On the one hand, under the action of gravity, the driven roller 6 can press on the top of the nonwoven film, that is, it is clamped on the top and bottom of the nonwoven film with the driving roller 4 respectively. On the other hand, the clamping bolt 11 can be adjusted according to actual needs. The end of the clamping bolt 11 is clamped with the inclined groove 10. Based on the downward force of the insert rod 8, the clamping force of the driven roller 6 and the driving roller 4 on the nonwoven fabric is increased. The purpose of this is that if the nonwoven film in the winding is strong enough, the clamping force of the driven roller 6 and the driving roller 4 on the nonwoven fabric should be increased as much as possible to facilitate the correction of the lateral position. If the nonwoven film in the winding is of average strength, the clamping force of the driven roller 6 and the driving roller 4 on the nonwoven fabric should be appropriately reduced to avoid irreversible deformation or even cracking of the nonwoven film during the correction of the larger lateral position.
[0025] Furthermore, the end of the clamping bolt 11 that fits into the inclined groove 10 is in an arc shape.
[0026] In the specific implementation process, it is worth noting that the arc-shaped design can avoid interference between the tightening bolt 11 and the inclined groove 10 during the adjustment process, reduce wear, and at the same time facilitate the relative movement between the inner wall of the inclined groove 10 and the tightening bolt 11.
[0027] In one feasible embodiment, a mounting plate 13 is provided on the upper side of the frame 1 away from the slide rail 2, and detection photoelectric sensors 14 are provided on both sides of the top of the mounting plate 13.
[0028] In the specific implementation process, it is worth noting that the detection photoelectric 14 can be set in an appropriate number according to actual needs. Its purpose is to detect the position of the boundary of the nonwoven fabric and, in conjunction with the external controller, determine the amount of correction. The specific model of the detection photoelectric 14 is not limited, as long as it meets the technical solution described in this embodiment. Then, the correction of the nonwoven fabric film is achieved by adjusting the position of the slide block 3.
[0029] In one feasible embodiment, an electric push rod 12 is fixedly connected to the side of the slide 3 near the mounting plate 13, and the end of the electric push rod 12 is fixedly connected to the top of the frame 1.
[0030] In the specific implementation process, it is worth noting that the purpose of setting the electric push rod 12 is to adjust the position of the slide block 3 relative to the slide rail 2 laterally. In this way, when the driven roller 6 and the driving roller 4 are holding the non-woven fabric film, the lateral position of the non-woven fabric film can be adjusted to achieve correction. The specific model of the electric push rod 12 is not limited, as long as it meets the technical solution described in this embodiment.
[0031] In one feasible embodiment, limit rods 15 are fixedly connected to both sides of the bottom of the mounting plate 13. The bottom of the limit rods 15 passes through the frame 1 and is movably connected to the frame 1. A fixing bolt 16 is pressed against one side of the limit rod 15, and the fixing bolt 16 is threadedly connected to the frame 1.
[0032] In the specific implementation process, it is worth noting that the limiting rod 15 is fixed to the frame 1 by the fixing bolt 16 to fix the mounting plate 13, and can be adjusted according to the height of the non-woven film.
[0033] In one feasible embodiment, a servo motor 5 is fixedly connected to one end of the drive roller 4, and the servo motor 5 is fixed to the surface of the slide block 3.
[0034] In the specific implementation process, it is worth noting that the specific model of the servo motor 5 is not limited, as long as it meets the technical solution described in this embodiment. The servo motor 5, the electric push rod 12 and the detection photoelectric sensor 14 are all connected to an external controller or connected to the automatic control end of the winding equipment to achieve mutual matching and meet the technical solution described in this embodiment.
[0035] 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.
