Description

Technical Field

[0001] This utility model relates to the field of cotton towel unwinding technology, and in particular to an automatic unwinding device for cotton towel rolls. Background Technology

[0002] The background technology of an automatic unwinding device for cotton soft towel rolls mainly relates to the application of automated mechanical equipment in the production process of cotton soft towels. Cotton soft towels are a type of sanitary napkin or paper towel commonly used in daily life. They are usually made of fiber materials that have been processed and rolled into rolls. During the production and processing, the rolls need to be continuously unwound for use in subsequent processing stages.

[0003] For ease of transport, fabric is usually collected in rolls. When needed, the rolls are gradually unloaded for processing. A single roll unloading device is used to unload the rolls of fabric. In existing technology, because the fabric is flexible, it is affected by many factors when unloading. The tension of the fiberglass cloth will change, damaging the fabric surface. At the same time, the fabric surface will also shift up and down during operation, affecting subsequent collection. Utility Model Content

[0007] By using the above technical solution, and by setting a belt to connect the first gear and the second gear, the unwinding roller can be driven to work, thus improving the stability of the device.

[0008] As a further improvement to the above solution, the adjustment mechanism includes a correction bracket and a moving roller bracket. A correction roller is rotatably connected to the top of the correction bracket, and an adjustment bracket is fixedly connected to the bottom of the correction bracket.

[0012] As a further improvement to the above solution, two correction brackets are provided, symmetrically positioned on both sides of the correction roller. Similarly, two adjustment brackets are provided, symmetrically positioned on both sides of the adjustment roller.

[0013] By using the above technical solution, and by setting two correction brackets and distributing them in a centrally symmetrical manner, the efficiency of the correction function and the stability of the operation are effectively improved.

[0014] As a further improvement to the above solution, the tension bracket fixing plate is provided in two forms, with the two tension bracket fixing plates symmetrically arranged on both sides with the tension roller as the center.

[0015] By using the above technical solution, and by setting two tension supports and distributing them symmetrically on both sides, the device can stretch and extend the fabric.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves the function of unwinding by setting a drive motor on the surface of the starter motor bracket. The drive motor drives the first gear and belt to rotate, which in turn drives the second gear to rotate the unwinding roller connected to the unwinding roller transmission rod.

[0019] This invention features a correction bracket in its adjustment mechanism. When the fabric reaches the correction bracket, the correction roller rotates and moves up and down on the surface of the correction bracket, bringing the soft cloth to the surface of the tension roller. The tension roller, through the gravity roller below, swings and rotates up and down, stretching the soft cloth to make it flatter. The stretched soft cloth is then sent to the guide roller for secondary stretching, effectively ensuring the flatness of the soft cloth. By setting an anti-fall platform at the bottom of the frame, the soft cloth is prevented from falling and getting stuck in the main machine, thus improving the safety of the device.
