Description

Technical Field

[0001] This utility model relates to the field of fabric treatment technology, specifically to an automatic rewinding device for a fabric adhesive wiping machine. Background Technology

[0002] Fabric rubbing is a process that utilizes the shearing force and extrusion force generated by the difference in roller speed ratios in a calender to evenly rub the adhesive material into the surface and gaps of the fabric, thus producing a semi-finished rubbing cloth. Depending on the application, rubbing cloths can be divided into uncured raw rubber rubbing cloths and vulcanized rubber rubbing cloths. Uncured raw rubber rubbing cloths, because the adhesive material is not yet cured, have strong adhesion and are sensitive to the environment. Before winding, they must be effectively isolated with a plastic film to prevent contamination by dust and impurities or deterioration of the adhesive material due to moisture, thereby ensuring the quality of subsequent processing.

[0003] Existing automatic winding devices in fabric adhesive application machines typically only have the function of winding the adhesive cloth itself, lacking a synchronous bonding and winding mechanism for the plastic film. In actual production, bonding the adhesive cloth to the plastic film often requires manual operation or a separate process, such as manually covering the plastic film before winding. This method has several drawbacks: First, manual operation is inefficient, increasing production time and labor costs; second, manual bonding makes it difficult to ensure uniform bonding between the film and the adhesive cloth, easily leading to problems such as air bubbles, wrinkles, or uneven tension; furthermore, without automated protection measures, the adhesive cloth is susceptible to external contamination or physical damage during placement, storage, or transportation, resulting in a decrease in product qualification rate and affecting overall production efficiency.

[0004] With the increasing level of industrial automation, traditional manual or semi-automatic winding methods can no longer meet the demands of modern manufacturing for efficient and high-quality production. Therefore, there is an urgent need for a device that can simultaneously apply and automatically wind up adhesive tape and plastic film to optimize the production process, improve the quality of adhesive tape, and reduce production costs. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic winding device for adhesive cloth in a fabric adhesive application machine, so as to at least solve the problem that the adhesive cloth and plastic film cannot be synchronously bonded and automatically wound up.

[0030] Example:

[0031] In this embodiment, an automatic rewinding device for the adhesive cloth used in a fabric adhesive application machine is provided, such as... Figure 1 As shown, the device includes a wiping cloth 1, a plastic film 2, a rubber roller 3, a first metal roller 4, a second metal roller 5, a third metal roller 6, a fourth metal roller 7, a fifth metal roller 8, and a supporting rod 9. The fifth metal roller 8, located at the bottom of the device, carries the rolled plastic film 2. It has a diameter of 150 mm and its surface is polished to reduce frictional resistance and ensure smooth release of the plastic film 2. In this embodiment, the plastic film 2 is a polyethylene film with a thickness of 0.05 mm, possessing excellent flexibility and adhesion; however, in other embodiments, it can be replaced with a polypropylene film or other materials with similar properties, depending on actual needs. After being released from the fifth metal roller 8, the plastic film 2 is guided sequentially by the fourth metal roller 7, the supporting rod 9, the second metal roller 5, and the first metal roller 4. The first metal roller 4, serving as the bonding point, has a diameter of 200 mm and its surface is coated with a wear-resistant coating. Through compression, it tightly bonds the wiping cloth 1 to the plastic film 2.

[0032] In this embodiment, the wiping cloth 1 is an unvulcanized raw rubber wiping cloth with a width of 1.2 meters and a thickness of 2 millimeters, entering the device from the output end of the fabric wiping machine; however, in other embodiments, vulcanized rubber wiping cloth can also be used to adapt to different production needs. The laminated wiping cloth 1 and plastic film 2 are guided by the first metal roller 4, the second metal roller 5, the third metal roller 6, and the rubber roller 3, and finally wound up by the fourth metal roller 7. A support rod 9 is fixedly installed between the fourth metal roller 7 and the second metal roller 5, made of stainless steel with a diameter of 30 millimeters, with both ends connected to the device frame via fixed seats. Its smooth surface ensures stable transmission of the plastic film 2. The rubber roller 3 has a diameter of 250 millimeters, its surface is covered with a 5-millimeter-thick wear-resistant rubber layer, it is fixed to the core by adhesive bonding, and is driven by a 2.2 kW motor to provide transmission power.

[0033] A guiding mechanism is provided between the first metal roller 4 and the second metal roller 5, employing an adjustable guide plate design and fixed to the device frame to ensure that the alignment accuracy of the plastic film 2 and the wiping cloth 1 is controlled within ±2 mm. A winding mechanism is provided on the fourth metal roller 7, connected to the shaft end via a high-precision bearing to ensure a smooth winding process; the roll diameter can reach 800 mm. The device also includes a control system using PLC technology, connected to the rubber roller 3 and the drive devices of each metal roller via wires, equipped with a touch screen operating interface for real-time monitoring and adjustment of parameters such as speed and tension. Each metal roller (first metal roller 4 to fifth metal roller 8) is made of high-strength alloy steel with a surface hardness of HRC50 or higher, supported by bearings on the device side plate to ensure long-term durability; however, in other embodiments, stainless steel can be selected to enhance corrosion resistance depending on environmental requirements.

[0034] The operating process of the device in this embodiment is as follows: The operator first installs the roll of plastic film 2 onto the fifth metal roller 8, and manually passes the starting end of the plastic film 2 sequentially through the fourth metal roller 7, the support rod 9, the second metal roller 5, and the first metal roller 4. During the threading process, manual adjustment is used to ensure that the tension is moderate, controlled between 10-15 Newtons. At the same time, the adhesive cloth 1 is led out from the output end of the fabric adhesive wiping machine, with its starting end aligned with the bonding position of the first metal roller 4. After the device is started, the fifth metal roller 8 releases the plastic film 2 at a speed of 10 revolutions per minute. Guided by the fourth metal roller 7, the plastic film 2 is kept flat by the support rod 9, and then, after adjustment by the second metal roller 5, finally reaches the first metal roller 4. Simultaneously, the adhesive cloth 1 enters the device at a speed of 5 meters per minute and merges with the plastic film 2 at the first metal roller 4.

[0035] The first metal roller 4 rotates at 12 revolutions per minute, and the extrusion pressure is adjusted to 50 Newtons via a spring device to ensure a tight bond between the wiping cloth 1 and the plastic film 2, forming a uniform composite material. The bonded composite material is guided by the second metal roller 5, the third metal roller 6, and the rubber roller 3, and finally wound into a roll by the fourth metal roller 7. The second metal roller 5 rotates at the same speed as the first metal roller 4, and its surface smoothness Ra value is less than 0.8 micrometers, ensuring a smooth transition of the composite material. The third metal roller 6 rotates at 11 revolutions per minute, with its tension finely adjusted to 20 Newtons to avoid overstretching. The rubber roller 3 rotates synchronously with the fourth metal roller 7 at 10 revolutions per minute, and its surface friction ensures that the composite material does not slip. The winding mechanism monitors the roll tension in real time using a tension sensor, controlling it between 25-30 Newtons to ensure the roll is tight and wrinkle-free. The control system collects the rotation speed and tension data of each roller through sensors and displays it on the touchscreen. If an abnormality is detected (such as tension exceeding the set range), the system automatically adjusts the motor power or suspends operation to protect the device and the material. In this embodiment, the control system uses a Siemens S7-1200 series PLC to ensure high reliability; however, in other embodiments, other brands of PLCs or microcontrollers can be selected to meet different cost requirements.

[0036] The device in this embodiment has significant practical advantages: through an integrated roller system and automated control, it achieves synchronous bonding and winding of the wiping cloth 1 and the plastic film 2, reducing the single winding time to less than 10 minutes and increasing production efficiency by approximately 60% compared to traditional manual methods. The precise collaboration of the guiding mechanism and tension control system ensures bonding uniformity of over 98%, and the tightness error of the wound roll is less than ±3 mm, effectively avoiding defects such as wrinkles and bubbles, and improving the quality of the wiping cloth 1. The modular design allows the device to adapt to wiping cloth 1 with widths of 0.8-1.5 meters and thicknesses of 1-3 mm, as well as different types of plastic film 2, enhancing production flexibility and meeting diverse market demands. Automated operation reduces the opportunity for manual contact with mechanical parts; operators only need to set parameters and monitor via a touchscreen, significantly reducing the risk of mechanical injury. The application of high-strength alloy steel rollers and stainless steel support rods 9, combined with a wear-resistant rubber layer, enables the device to have a continuous operating life exceeding 5000 hours and a maintenance cycle extended to more than 6 months. In this embodiment, the device frame is made of carbon steel coated with anti-corrosion paint to balance cost and durability; however, in other embodiments, a stainless steel frame can be used to further enhance corrosion resistance. Through the above design, this invention provides an efficient, stable, and universal winding solution for the fabric adhesive application industry, fully meeting the high standards of modern production.

[0037] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
