Description

Technical Field

[0001] This utility model relates to the field of roller technology for coating machine production, and in particular to a floating roller tension control mechanism. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of specific functional adhesive, coating, or ink, and after drying, cuts it into sheets or rewinds it. It often uses a dedicated multi-functional coating head, enabling various forms of surface coating. Both the unwinding and rewinding of the coating machine are equipped with a full-speed automatic film splicing mechanism. In the existing control logic of the traction section of the coating machine, since it uses real-time feedback values ​​from the tension sensor, tension is often adjusted directly by regulating the motor speed. This method is prone to causing severe tension fluctuations during film operation, affecting the tension adjustment effect. Therefore, this application proposes a floating roller tension control mechanism. Utility Model Content

[0003] The purpose of this invention is to address the problem of severe tension fluctuations in the film material during operation caused by adjusting the motor speed to control tension in the original control logic of the coating machine traction section, which exists in the background art. A floating roller tension control mechanism is proposed.

[0004] The technical solution of this utility model is as follows: a floating roller tension control mechanism, including a wall panel, a control mechanism is provided on one side of the wall panel, the control mechanism includes a mounting base, a rotating shaft is connected to one side of the mounting base, a rotating buckle is sleeved on the outer ring of the rotating shaft, a cylinder is connected to the bottom of the rotating buckle, and a resistance ruler is provided inside the cylinder.

[0005] A rocker arm mechanism is provided on one side of the wall panel.

[0006] Optionally, the control mechanism further includes a floating seat, a rotating shaft two connected to one side of the floating seat, a rotating buckle two sleeved on the outer ring of the rotating shaft two, the top of the rotating buckle two connected to a cylinder one, and a floating roller connected to one side of the floating seat.

[0007] Optionally, the control mechanism further includes a limiting seat, the top of which has a limiting groove.

[0008] Optionally, the rocker arm mechanism includes a rocker arm, one side of which is connected to a rubber roller, and another side of which is connected to a rotating shaft.

[0009] Optionally, the rocker arm mechanism further includes a positioning sleeve, the inner ring of which is fitted with a second cylinder, one side of which is connected to a third rotating shaft.

[0010] Optionally, the rocker arm mechanism further includes a mounting plate, on one side of which a motor is provided. The output end of the motor is connected to a bevel gear one, which meshes with a bevel gear two. A pressure roller is connected to one side of the bevel gear two. The rocker arm mechanism also includes a bracket, on one side of which the pressure roller is connected.

[0011] Optionally, a tension detection seat is provided on one side of the wall panel, an auxiliary roller two is connected to one side of the tension detection seat, a mounting seat two is connected to one side of the wall panel, an auxiliary roller one is connected to one side of the mounting seat two, a mounting seat three is connected to the top of the wall panel, an auxiliary roller three is connected to one side of the mounting seat three, and a transition roller is connected to one side of the wall panel.

[0012] Compared with the prior art, this application includes at least one of the following beneficial technical effects: The tension control mechanism controls the tension by adjusting the swing of the floating roller through the extension and retraction of the cylinder. When the tension is low, it means that the film is loose during feeding, and the floating roller swings in one direction. When it swings in the other direction, the tension will increase and tighten the stored material. The tension detection seat detects the tension and feeds it back to the cylinder. The resistance ruler can reflect the amount of extension and retraction of the cylinder and adjust the swing amplitude of the floating roller. The resistance ruler senses the tension information through the extension and retraction of the cylinder and transmits the signal to the motor, thereby controlling the speed of the motor to make the film feeding tension tend to be stable, which can ensure that the equipment maintains relatively accurate tension control during operation.

A floating roller 211 is connected to one side of the floating seat 26. The control mechanism 2 also includes a limiting seat 29, with a limiting groove 210 formed on the top of the limiting seat 29. The mounting base 21 is fixedly connected to the wall panel 1 by bolts, and the rotating buckle 23 is rotatably sleeved on the wall panel 1. On the outer ring of the rotating shaft 22, and fixedly connected to the cylinder 24, the resistance ruler 25 is used to reflect the amount of extension and retraction of the cylinder 24 to adjust the swing amplitude of the floating roller 211. The resistance ruler 25 senses the tension information through the extension and retraction of the cylinder 24 and transmits the signal to the motor 9. One side of the floating seat 26 is rotatably connected to the wall plate 1. The rotating buckle 28 is rotatably sleeved on the outer ring of the rotating shaft 27 and fixedly connected to the cylinder 24.

The limiting groove 210 is used to limit the swing amplitude of the floating seat 26. When adjusting the tension, the cylinder 24 extends and retracts the floating seat 26 at the same time, so that the resistance ruler 25 also senses the tension information of the extension and retraction, thereby transmitting the signal to the motor 9, so that the motor 9 adjusts its speed according to the amount of extension and retraction of the cylinder 24 to realize the adjustment of the tension.

[0026] It should be added that, such as Figure 1 , Figure 2 and Figure 4As shown, a rocker arm mechanism is provided on one side of the wall panel 1.

The bracket 14 is welded to the wall plate 1, with one side rotatably connected to the pressure roller 12. During the coating machine winding process, the cylinder 2 19 pushes the rocker arm 13 to disengage the rubber roller 15 from the pressure roller 12, and after the material is wound onto the outer wall of the pressure roller 12, the cylinder 2 19 retracts, causing the rubber roller 15 to reattach to the outer wall of the pressure roller 12, thereby achieving auxiliary and limiting material movement.

[0027] In addition, such as Figure 1 and Figure 2 As shown, a tension detection seat 6 is provided on one side of the wall panel 1, and an auxiliary roller 7 is connected to one side of the tension detection seat 6.

[0028] In this embodiment, during tension adjustment, the cylinder 24 simultaneously extends and retracts the floating seat 26, causing the resistance gauge 25 to sense the tension information of the extension and retraction. This signal is then transmitted to the motor 9, which adjusts its speed according to the extension and retraction of the cylinder 24, thereby adjusting the tension. The bevel gear 10 is connected to the motor 9 by a key, and through the meshing principle, the bevel gear 11 drives the pressure roller 12 to rotate. The bracket 14 is welded to the wall panel 1, with one side rotatably connected to the pressure roller 12. During the coating machine winding process, the cylinder 19 pushes the rocker arm 13 to disengage the rubber roller 15 from the pressure roller 12, winding the material onto the outer wall of the pressure roller 12. Then, the cylinder 19 retracts, causing the rubber roller 15 to reattach to the outer wall of the pressure roller 12, thus assisting and limiting the movement of the material. The resistance gauge 25 is used to reflect the extension and retraction of the cylinder 24 to adjust the swing amplitude of the floating roller 211.
