Description

Technical Field

[0001] The utility model relates to the technical field of mattress equipment production and processing, in particular to a magic buckle unwinding mechanism with stable unwinding and long endurance. Background Art

[0002] Adult diapers are usually equipped with Velcro, which is used for fastening. Since the amount of Velcro material used in an adult diaper is very small, only 75mm is used in a 700mm long adult diaper, which means that the linear speed of unwinding this material is much lower than that of other materials. In addition, the Velcro material itself is very strong and not easy to deform. Due to the above factors, the current Velcro automatic material unwinding method requires the use of an air shaft, a servo motor (or a variable frequency motor), an automatic material connection, a material storage device, a tension control device, etc. Such a structure occupies a large space, has a high production cost, and generates waste when connecting the materials.

[0003] Therefore, in order to correct the above defects, we propose a magic buckle unwinding mechanism with stable unwinding and long battery life. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a magic buckle unwinding mechanism with stable unwinding and long endurance, comprising a magic buckle passive unwinding device, a material guide roller one, two groups of fixed material transition wheels, two groups of material guide rollers two, a material traction pressure wheel and a material traction driving wheel, the material guide roller one is located below the magic buckle passive unwinding device, and the material guide roller one, a group of fixed material transition wheels, a group of material guide rollers two are on the same horizontal line with the material tangent point, and the material traction driving wheel is on the upper left of the group of material guide rollers two, and the material traction pressure wheel is at the upper end of the material traction driving wheel, and the two press the material, and the material traction pressure wheel, another group of fixed material transition wheels, another group of material guide rollers two are on the same horizontal line with the material tangent point.

[0006] Furthermore, the Velcro passive unwinding device comprises a long supporting roller shaft, on which two symmetrical material limiting rings are mounted.

[0007] Furthermore, the fixed material transition wheel includes a support rod having two adjacent and vertical guide rollers, the material passes between the two guide rollers, and the two guide rollers press the material.

[0008] Furthermore, the material traction pressing wheel includes a pressing wheel and a cylinder, and the cylinder controls the lifting and lowering of the pressing wheel.

[0009] Furthermore, the material traction driving wheel includes a driving wheel and a driving motor providing power to the driving wheel.

[0010] Furthermore, the material guide roller 2 in the last group is also installed with a material limiting ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects: compared with the existing Velcro automatic material unwinding method, the device saves 2 air expansion shafts, 2 sets of servo motors (or variable frequency motors), 1 set of automatic material connection, 1 set of material storage device, and 1 set of tension control device for one set of materials. The cost is reduced by more than 90%, and the installation space on the host is saved. The production plan can be completed with one roll of Velcro material, which saves time and labor, and avoids waste generated when connecting materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1-2 A magic buckle unwinding mechanism with stable unwinding and long endurance, comprising a magic buckle passive unwinding device 1, a guide roller 1 2, two sets of fixed material transition wheels 3, two sets of guide rollers 2 4, a material traction pressure wheel 5 and a material traction driving wheel 6, the supporting long roller shaft 11 is installed on the wall panel 8 through a turntable, the guide roller 1 2, the fixed material transition wheel 3, the guide roller 2 4, the material traction pressure wheel 5, and the material traction driving wheel 6 are all respectively passed through the shaft rod and the wall panel 8, and the driving motor drives the material traction driving wheel 6 to rotate through the shaft rod;

[0019] Put the magic hook coil 12 on the supporting long roller shaft 11 (this material is passively unwound), use two material limiting rings 7 to clamp the magic hook coil 12, and pass the initial end of the magic hook coil 12 around the lower guide roller 2, and then enter the first group of fixed material transition wheels 3.
