Description

Technical Field

[0001] This utility model relates to a roller center quick adjustment device, specifically a tension roller center quick adjustment device suitable for winding and conveying systems of industrial equipment such as coating, IC manufacturing, printing, and fiber winding, belonging to the field of winding control technology. Background Technology

[0002] The winding system is one of the common basic systems in industrial equipment such as coating, IC manufacturing, printing, and fiber winding. It winds thin film rolls into cylindrical material rolls for easy storage and transportation. The quality of winding directly affects the service life and quality of the thin film rolls. The winding tension of the winding system is an important factor affecting the winding quality. Excessive winding tension can easily cause the roll to deform and crack, while insufficient winding tension can easily lead to loose and untight rolls, affecting the flatness of the winding.

[0003] Winding systems are typically versatile, meaning they can be used to wind rolls of different thicknesses and toughnesses. When changing rolls, the winding tension is usually adjusted by changing the center position of the tension roller shaft to accommodate different roll specifications. However, traditionally, adjusting the center position of the tension roller shaft in a winding system requires stopping the machine, removing the entire tension roller shaft mounting base, and then installing a mounting base corresponding to the roll specification. This constant switching of mounting bases for different roll specifications not only increases the workload for operators and reduces efficiency but also decreases equipment utilization. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a rapid adjustment device for the center of the tension roller shaft. For roll materials of different thicknesses and toughness specifications, the device can adjust the center position of the tension roller shaft without replacing the mounting base of the tension roller, thereby improving adjustment efficiency and equipment utilization.

[0005] To achieve the above objectives, this tension roller shaft center quick adjustment device includes an adjustment sleeve, a tension roller fixing seat, an adjustment support frame, and a mounting positioning seat.

[0006] The adjusting sleeve includes a sleeve cap, a sleeve, a limiting rod, and a limiting adjustment block; the sleeve cap is fixedly installed on the upper end of the vertically arranged sleeve; the limiting adjustment block is located below the sleeve, and a clamping and positioning mechanism is provided at the position directly below the sleeve corresponding to the limiting adjustment block; the vertically arranged limiting rod passes through the sleeve cap and the limiting adjustment block, and a limiting position adjustment mechanism is provided on the limiting rod;

[0007] The tension roller fixing seat is fixedly installed on the sleeve, and the tension roller fixing seat is provided with a tension roller bearing seat mounting structure;

[0008] The adjustment support frame is located below the limit adjustment block and includes an adjustment screw, an adjustment nut, a spring, and a fixed seat. The vertically arranged adjustment screw is coaxially inserted into the inside of the sleeve, and the top end of the adjustment screw, which passes through the sleeve cover, is threadedly connected to the adjustment nut. The limit adjustment block is clamped and positioned on the adjustment screw by a clamping and positioning mechanism. The bottom end of the adjustment screw is fixedly installed and connected to the fixed seat. The two ends of the spring sleeved on the adjustment screw abut against the limit adjustment block and the sleeve, respectively.

[0009] The mounting and positioning seat is fixedly installed on the fixed seat.

[0010] As a further improvement of this utility model, the tension roller fixing seat is an L-shaped structure including a vertical mounting surface and a horizontal mounting surface. The tension roller fixing seat is fixedly mounted on the sleeve through the vertical mounting surface, and the tension roller bearing seat mounting structure is set on the horizontal mounting surface of the tension roller fixing seat.

[0011] As a further improvement of this utility model, the mounting and positioning seat includes a reference positioning block and an adjusting bolt, one end of which is mounted and connected to the reference positioning block, and the other end is threadedly connected to the fixed seat.

[0012] As a further improvement of this utility model, the fixed base is provided with a bolt mounting elongated hole groove, and the length direction of the bolt mounting elongated hole groove is set along the adjustment direction of the adjusting bolt.

[0013] In one embodiment of this utility model, the lower inner part of the sleeve is provided with a large-diameter section including a spring positioning end face, and the top end of the spring passes into the sleeve and abuts against the spring positioning end face.

[0016] Compared with existing technologies, this tension roller shaft center quick adjustment device can be directly installed on the winding equipment, and the tension roller, including the tension roller bearing seat, can be fixedly mounted on two symmetrically arranged tension roller fixing seats through the tension roller bearing seat mounting structure. When it is necessary to adjust the center position of the tension roller shaft, the adjusting nut can be rotated forward to press down the sleeve cover, thereby driving the tension roller fixing seat to move downward. By rotating the adjusting nut in the reverse direction, the tension roller fixing seat is driven upward by the spring's return force. At the same time, the limit rod can limit the overall lifting range. The position of the limit adjusting block can be adjusted and locked in the adjusting screw, thereby applying different preload forces to the spring, which facilitates the setting of the tension roller's tension threshold.

[0025] The adjustment support frame 3 is located below the limit adjustment block 14 and includes an adjustment screw 31, an adjustment nut 32, a spring 33, and a fixed seat 34. The vertically arranged adjustment screw 31 is coaxially connected to the inside of the sleeve 12 and passes through the sleeve cover 11. The top end of the adjustment screw 31 is threadedly connected to the adjustment nut 32. The limit adjustment block 14 is clamped and positioned on the adjustment screw 31 by a clamping and positioning mechanism. The bottom end of the adjustment screw 31 is fixedly connected to the fixed seat 34. The two ends of the spring 33, which is sleeved on the adjustment screw 31, abut against the limit adjustment block 14 and the sleeve 12, respectively.

[0026] The mounting and positioning base 4, used for reference positioning, is fixedly mounted on the fixed base 34. It includes a reference positioning block 41 and an adjusting bolt 42. The reference positioning block 41 is used for reference positioning on the equipment frame. One end of the adjusting bolt 42 is mounted on the reference positioning block 41, and the other end is threadedly connected to the fixed base 34.
