Description

Technical Field

[0001] This utility model relates to the field of fabric tensioning technology, specifically to a material roller mechanism for automatically tensioning fabric. Background Technology

[0002] Surgical packs are required during surgery. The surgical gowns and drapes inside these packs are typically quite large and need to be folded before being placed inside. During the folding of the surgical drapes, the fabric is moved by the feed rollers and traction rollers on the folding device. Guided by guide rods, the fabric forms a wave-like structure, and the traction rollers compress and fold the fabric. There is a speed deviation in traction and feed between the feed rollers and traction rollers at the beginning and end of the operation. Therefore, the fabric may be too tight or too loose between the feed rollers and traction rollers. Both excessive tightness and looseness can easily lead to wrinkles or unevenness after folding. To solve this problem, an automatic fabric tensioning roller mechanism is proposed. Utility Model Content

[0003] The purpose of this invention is to provide an automatic fabric tensioning roller mechanism, which solves the problem of the fabric being too tight or too loose between the discharge roller group and the traction roller group.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic tensioning fabric roller mechanism, comprising a traction roller group, wherein a mounting frame is fixedly installed on the discharge side of the traction roller group, and at least one tensioning mechanism one and one tensioning mechanism two are fixedly installed on the mounting frame along the fabric conveying direction;

[0005] The tensioning mechanism includes two sets of elastic buffer frames and a guide roller disposed between the two sets of elastic buffer frames. The elastic buffer frames are fixedly installed on the mounting frame and provide elastic buffering in the vertical direction.

[0006] The tensioning mechanism 2 includes two sets of elastic buffer frames 2 and a guide roller 2 disposed between the two sets of elastic buffer frames 2. The elastic buffer frames 2 are fixedly installed on the mounting frame and the elastic buffer frames 2 provide elastic buffering in the vertical direction.

[0007] The fabric output by the traction roller group passes over the guide roller 1 of tensioning mechanism 1 and the guide roller 2 of tensioning mechanism 2 respectively. The wrapping height of tensioning mechanism 1 is lower than that of tensioning mechanism 2. The guide roller 1 is located above the fabric that passes through, and the guide roller 2 is located below the fabric that passes through.

[0008] Preferably, the mounting bracket is fixedly mounted on the roller frame of the traction roller assembly by means of angle brackets and fasteners.

[0009] Preferably, the mounting bracket is U-shaped, and the support arm of the mounting bracket is provided with a transverse adjustment groove. The tensioning mechanism one and the tensioning mechanism two are locked onto the adjustment groove by nuts, and the installation distance between the tensioning mechanism one and the tensioning mechanism two is adjustable along the adjustment groove.

[0010] Preferably, the elastic buffer frame includes a connecting seat, a movable shaft, a spring frame, a limiting nut, and a roller seat. The connecting seat has a stud that passes through an adjustment groove and is locked to the nut. The limiting nut is threaded onto the upper threaded section of the movable shaft. The connecting seat is movably sleeved on the movable shaft. The spring frame is fixedly sleeved on the movable shaft. The connecting seat is sandwiched between the limiting nut and the spring frame. The roller seat is fixed to the bottom of the movable shaft, and a guide roller is installed on the roller seat.

[0011] Preferably, a nut seat is provided at the lower end of the spring frame, and the spring frame is fixed to the threaded section at the lower end of the movable shaft through the nut seat.

[0012] Preferably, the second elastic buffer frame includes a second connecting seat, a second movable shaft, a second spring frame, and a second roller seat. The second connecting seat is provided with a stud that passes through an adjustment groove and is locked with a nut. The second connecting seat is movably sleeved on the second movable shaft. The second spring frame is fixedly sleeved on the second movable shaft. The second connecting seat is located at the bottom of the second spring frame. The second roller seat is fixed at the bottom of the second movable shaft. A second guide roller is installed on the second roller seat.

[0013] Preferably, the upper end of the second spring frame is provided with a second nut seat, and the second spring frame is fixed to the upper threaded section of the second movable shaft through the second nut seat.

[0014] This utility model has the following beneficial effects:

[0015] This invention, by setting up an mounting frame, tensioning mechanism one, and tensioning mechanism two, elastically tensions the fabric output from the traction roller group. This allows for automatic adjustment of the fabric tension when speed deviations occur between the discharge roller group and the traction roller group. Under the appropriate elastic tension of tensioning mechanism one and tensioning mechanism two, when the speed of the traction roller group is greater than that of the discharge roller group, the fabric will loosen, and tensioning mechanism one and tensioning mechanism two will tighten the fabric under the action of spring extension. When the speed of the traction roller group is less than that of the discharge roller group, the fabric will be too tight, and tensioning mechanism one and tensioning mechanism two will loosen the fabric under the action of spring contraction, thus achieving the purpose of adaptive adjustment.
