Description

Technical Field

[0001] The invention relates to the technical field of rubber bending rollers, in particular to an actively driven rubber bending roller. Background Art

[0002] In industrial applications such as textile printing and dyeing, film processing, and transfer printing, the flatness of the substrate plays a vital role in ensuring the quality of the final product. In these applications, the surface of the substrate must remain highly uniform and smooth to avoid any flaws or defects during the production process. In traditional rubber bending roller technology, the bending roller usually adopts a passive drive method, which relies on the action of external force to achieve the bending action of the bending roller. However, this passive drive method has some significant problems, including slow response speed, low control accuracy, and high energy consumption.

[0003] Although this passively driven rubber bending roller is simple in design and low in cost, it has obvious limitations. When the passively driven rubber bending roller is used to process sensitive and easily deformed substrates, the speed and tension of the bending roller cannot be accurately controlled, which can easily cause wrinkles or uneven stretching of the substrate, which will seriously affect the quality of the product. During the production process, any minor defects in the substrate may result in the failure of the final product, resulting in economic losses and reduced production efficiency.

[0004] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop an actively driven rubber bending roller. Summary of the invention

DETAILED DESCRIPTION

[0021] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a technical solution for an actively driven rubber bending roller: comprising a bending roller body, the bending roller body comprising a bending shaft 1 and a rubber sleeve 4 sleeved outside the bending shaft. Multiple sets of intermediate rotors 401 are installed in intervals between the bending shaft 1 and the rubber sleeve 4, and the intermediate rotors are connected through intermediate bearings 402.

[0023] The left side of the bending shaft 1 is an adjustment part, and is provided with an adjustment shaft end 12, and the right side is a driving part, and is provided with a driving shaft end 11. The adjustment shaft end 12 is connected to the adjustment shaft seat 3, and the outer wall of the adjustment shaft end 12 is sleeved with an adjustment shaft sleeve 31, and the outer wall of the adjustment shaft sleeve 31 and the inner wall of the adjustment shaft seat 4 are both provided with notches, and an adjustment ball 32 is provided in the notch.

[0024] Among them, a driving shaft seat 2 is arranged outside the driving shaft end 11, and the driving shaft end 11 and the driving shaft seat 2 are connected through a driving bearing 21. The driving shaft end 11 is used to connect a driving device, which can be a motor or other power source, and the driving shaft end 11 drives the rubber sleeve to rotate to realize the driving of the rubber bending roller.

[0025] The adjusting sleeve 31, the adjusting ball 32 and the adjusting seat 3 cooperate with each other to adjust the curvature direction of the bending axis. When the curvature of the bending axis 1 needs to be adjusted, the position of the adjusting ball 32 can be changed by rotating the adjusting sleeve 31, thereby adjusting the curvature of the bending axis 1.

[0026] Among them, a tail rotor 403 is arranged between the side of the bending shaft 1 close to the driving part and the rubber sleeve, and is connected through a bearing. The tail rotor 403 is connected to the driving shaft end 11 to ensure a stable connection between the driving device and the rubber sleeve 4.

[0027] Among them, a first rotor section 41 is arranged between the side of the bending shaft 1 close to the adjustment part and the rubber sleeve, and the first rotor section is connected through a bearing. An end cover 43 is arranged on the outside of the first rotor section 41, a TC oil seal 42 is arranged between the inside of the end cover 43 and the bending shaft 1, and an RB dustproof oil seal 44 is arranged between the outside of the end cover 43 and the bending shaft.

[0028] Among them, a drive shaft mounting seat 51 is arranged outside the tail rotor 403, a round nut 54 is connected to the outer thread of the bent shaft inside the drive shaft mounting seat 51, and a non-slip washer 55 is arranged on the adjacent side of the round nut. The round nut and the non-slip washer are used to fix the position of the tail rotor 403 to ensure its stable connection with the drive shaft end 11.

[0029] The outer edge of the drive shaft mounting seat 51 is sleeved with a tapered outer ring 52 , and the tapered outer ring 52 is threadedly connected to the drive shaft mounting seat 51 , and a tapered inner ring 53 is arranged inside the tapered outer ring 52 .

[0030] The end cover 43 and the drive shaft mounting seat 51 are respectively connected to the first rotor section 41 and the tail rotor section 403 through fixing bolts 45 .

[0031] When the drive shaft end 11 is rotated, the tail rotor 403 and the rubber sleeve 4 are driven to rotate, thereby realizing active drive. The bending shaft 1 does not rotate with the drive shaft end 11. When the bending shaft 1 is rotated, the angle of the arc is adjusted by adjusting the shaft sleeve 31 and the adjusting ball 32. This design ensures that the speed and tension of the bending roller can be accurately controlled, thereby effectively avoiding the problem of wrinkles or uneven stretching of the substrate during the processing process.

[0032] In addition, by using the adjusting sleeve 31 and the adjusting ball 32 in combination, the curvature direction of the bending shaft 1 can be easily adjusted to adapt to substrates of different thicknesses and materials, thereby increasing the application range and flexibility of the equipment. This adjustment mechanism allows the operator to quickly adjust the bending degree of the bending roller according to actual production needs, thereby improving production efficiency.

[0033] The design of the tail rotor 403 and the first rotor 41 of the present invention ensures a stable connection between the drive device and the rubber sleeve 4, and improves the overall mechanical strength and durability. At the same time, the end cover 43 and the drive shaft mounting seat 51 are provided to effectively prevent the intrusion of dust and oil, and ensure the cleanliness and long-term stable operation of the equipment.

[0034] In summary, the active drive rubber bending roller of the present invention not only solves the problems existing in the traditional passive drive mode, but also has significant advantages in improving production efficiency and product quality. Its characteristics of fast response speed, high control accuracy and low energy consumption make the present invention have broad application prospects in industrial application fields such as textile printing and dyeing, film processing, and transfer printing.
