Description

Technical Field

[0001] The utility model belongs to the technical field of paper towel production, in particular to a paper feeding drive shaft. Background Art

[0002] Paper towels are disposable sanitary paper made from plant fibers (usually wood pulp) with excellent absorbency, softness, and cleanliness. They are designed for personal hygiene, such as wiping, wiping sweat, or cleaning. Common product forms include paper handkerchiefs, boxed tissues, and napkins. Paper towel production involves several key steps: pulping, where raw materials (such as wood, bamboo, and bagasse) are processed into fiber pulp; papermaking, where the pulp is formed into paper and its quality is enhanced through processes such as drying and calendering; and processing, including slitting, folding, and packaging, which transform the paper into the final paper towel product. The paper feed drive shaft is a component in paper towel production or dispensing equipment. Its primary function is to provide power during paper transport and ensure that the paper moves along the correct path. Existing paper feed drive shafts use adjustable stoppers on both sides to prevent the paper from moving around the drive shaft. However, these stoppers require manual unlocking to adjust the spacing between the two stoppers, which slows production speed and equipment efficiency and is time-consuming and labor-intensive.

[0003] For example, the utility model with announcement number CN220664381U discloses a paper feeding drive shaft. In this patent scheme, it uses two limit components to achieve the limitation of both sides of the paper towel on the drive shaft. When the distance between the two limit components needs to be adjusted, the locking knobs on the two limit components are loosened respectively to release the lock of the positioning ring sleeve and then push the positioning ring sleeve to move on the rubber shaft tube to adjust the distance between the two limit ring plates. It requires personnel to manually adjust the spacing between the limit parts on both sides, especially when frequent adjustments are required. It is time-consuming, affecting the continuity and efficiency of the production line, and also increasing the workload of personnel. Utility Model Content

[0004] In view of this, the utility model addresses the shortcomings of the existing technology and provides a paper feed drive shaft that automatically adjusts the spacing between the limit plates on both sides to quickly adapt to papers of different sizes without stopping the machine, thereby speeding up production, reducing the need for manual operation, and alleviating the workload of workers.

[0005] The two lever arrangement comprises a bottom end of a shaft, and the bottom end of the shaft is fixedly mounted on the support frame, and the bottom end of the shaft is connected to the support frame by a movable frame. The movable frame is movable between the support frame and the support frame.

[0006] As a further improvement of the present invention, mounting components are respectively provided on the left and right sides of the lower end of the frame plate. The mounting components include mounting plates respectively provided on the left and right sides of the lower end of the frame plate. Two mounting holes are provided inside the two mounting plates.

[0007] As a further improvement of the present invention, the lifting mechanism includes two electric push rods arranged on the left and right sides of the frame plate, the left and right positions of the two electric push rods correspond, and the telescopic ends of the two electric push rods are respectively connected to the lower ends of adjacent sliding blocks.

[0008] As a further improvement of the present invention, a control panel is provided on the left side of the upper end of the frame plate, and the electric push rod 1 and the electric push rod 2 are both electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] Firstly, by connecting the shaft to an external electric drive mechanism, installing the frame plate to a suitable position, passing the paper towel through the shaft, and then turning on the external electric drive mechanism to rotate the shaft, the paper towel can be transported. At the same time, the limit plates on both sides can prevent the paper towel from moving during the transportation process, making the paper towel transportation more stable.

[0011] Secondly, by controlling the control panel to turn on the electric push rod and running it, the telescopic end drives the rotating frame to move forward, and the connecting frame inside it rotates and contracts, thereby making the limit plates on the rotating seats on both sides approach each other, so that the distance between the limit plates on both sides becomes smaller. Conversely, the telescopic end of the electric push rod can be controlled to contract through the control panel to increase the distance between the limit plates on both sides, thereby quickly and automatically adjusting the distance between the limit plates on both sides. Automatic adjustment of the distance between the limit plates on both sides can quickly adapt to different sizes of paper without stopping the machine, thereby speeding up production, reducing the need for manual operation, and also reducing the workload of workers.

[0012] Third, by controlling the control panel to open the second electric push rod, the telescopic end can drive the shaft cylinder between the sliding blocks on both sides to move up and down, making it convenient for personnel to fine-tune the tension of the paper during transmission, which can keep the paper flat and avoid wrinkles and tears, especially on high-speed production lines.

[0013] Fourthly, the paper feed drive shaft can be quickly installed in a suitable position through the mounting holes on the mounting plate, which is convenient for personnel to install and can quickly put the paper feed drive shaft into use. BRIEF DESCRIPTION OF THE DRAWINGS
