Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric conveying, in particular to a non-woven fabric conveying deviation-correcting device. Background Art

[0002] The non-woven fabric conveying correction device is a device that corrects the deviation of the non-woven fabric during the conveying process. The existing non-woven fabric correction device is generally composed of a non-woven fabric deviation detection component and a non-woven fabric correction component. The deviation detectors are set on both sides of the non-woven fabric to detect the deviation of the non-woven fabric. After the non-woven fabric deflects, the push rod in the non-woven fabric correction component pushes the non-woven fabric to move on the winding roller to achieve the correction of the non-woven fabric after the deviation.

[0003] When conveying multi-layer non-woven fabrics, in the process of correcting the deviation back and forth by pushing the multi-layer non-woven fabrics to move on the winding roller, part of the inner layer of the multi-layer non-woven fabrics is prone to be suspended in the air, and the non-woven fabrics above the suspended part and the non-woven fabrics below rub against each other, causing wrinkles in the non-woven fabrics and affecting the flatness of the non-woven fabrics. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a non-woven fabric conveying and correcting device, which is used to solve the problem that the existing non-woven fabric correcting device easily causes wrinkles on the non-woven fabric on the winding roller to affect the flatness by pushing multiple layers of non-woven fabric to move on the winding roller for correction.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A non-woven fabric conveying and correcting device comprises two mounting frames which are symmetrically arranged on the left and right, side support frames are arranged on the top of the two mounting frames facing away from each other, push rods are fixedly installed horizontally on the side support frames, a turntable is rotatably connected to the end of each push rod piston rod, a same winding roller is horizontally installed on the top of the two mounting frames, and the turntable is located at both ends of the winding roller, two limit rings are fixedly installed at both ends of the winding roller, and the limit rings are located on the left and right sides of the mounting frames, and non-woven fabric is wound outside the winding roller.

[0007] Preferably, the winding roller is mounted on the top of the two mounting frames through an open ball bushing.

[0008] Preferably, the distance between the two limiting rings on one end of the winding roller is greater than the lateral width of the mounting frame.

[0009] Preferably, two mounting cross bars symmetrically arranged on the frame are provided downstream of the mounting frame, each of the mounting cross bars is slidably connected to a sliding frame, and an offset detector corresponding to the non-woven fabric is fixedly installed on the sliding frame.

[0010] Preferably, a locking bolt supported on the mounting cross bar is threadedly connected to the sliding frame.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model provides independently driven push rods on both sides of the winding roller, and the push rods push the winding roller to move laterally for overall deviation correction. Whether it is a single-layer non-woven fabric or a multi-layer non-woven fabric, synchronous deviation correction can be achieved to avoid wrinkles in the non-woven fabric. Compared with the way in which traditional deviation correction components push the non-woven fabric, the way in which the utility model pushes the winding roller can correct the deviation multiple times without causing wrinkles in the non-woven fabric, has stronger practicality, ensures the flatness of the non-woven fabric, and solves the problem that the existing non-woven fabric correction device uses the way in which the multi-layer non-woven fabric is pushed to move on the winding roller for deviation correction, which easily causes wrinkles on the non-woven fabric on the winding roller and affects the flatness.

[0017] 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.

[0018] like Figure 1-3 As shown, the utility model provides a technical solution: a non-woven fabric conveying and correcting device, comprising two mounting frames 1 symmetrically arranged on the left and right;

[0019] The top of the two mounting frames 1 facing away from each other is provided with a side support frame 101, a push rod 2 is horizontally fixedly installed on the side support frame 101, and a winding roller 4 is installed on the top of the two mounting frames 1 through an open ball bushing 102, and a turntable 3 is rotatably connected to the piston rod end of each push rod 2. The same winding roller 4 is horizontally installed on the top of the two mounting frames 1, and the turntable 3 is located at both ends of the winding roller 4;

[0020] The distance between the two limiting rings 401 on one end of the winding roller 4 is greater than the lateral width of the mounting frame 1, so that the winding roller 4 is installed and positioned, and at the same time, space is given for the winding roller 4 to move laterally on the mounting frame 1. Two limiting rings 401 are fixedly installed at both ends of the winding roller 4, and the limiting rings 401 are located on the left and right sides of the mounting frame 1. The non-woven fabric 5 is rolled up outside the winding roller 4;

[0021] Two mounting cross bars 6 symmetrically arranged on the frame are arranged downstream of the mounting frame 1, and a sliding frame 7 is slidably connected to each mounting cross bar 6, and an offset detector 8 corresponding to the non-woven fabric 5 is fixedly installed on the sliding frame 7. The offset detector 8 detects the lateral offset distance of the non-woven fabric 5 to ensure timely adjustment of the position of the winding roller 4 on the push rod 2. A locking bolt 701 supported on the mounting cross bar 6 is threadedly connected to the sliding frame 7 to adjust the position of the sliding frame 7 on the mounting cross bar 6.

[0022] Working principle:

[0023] According to the width and position of the non-woven fabric 5, the lateral position of the offset detector 8 is adjusted. The offset detector 8 detects the offset of the non-woven fabric 5 during the conveying process. When the non-woven fabric 5 is offset, the piston rod of the push rod 2 in the opposite direction of the offset pushes the turntable 3 to move laterally, so that the turntable 3 and the winding roller 4 are in contact and push the winding roller 4 to move laterally for deviation correction. The turntable 3 rotates on the piston rod of the push rod 2 to adapt to the rotation of the winding roller 4, and does not affect the conveying of the non-woven fabric 5.
