Description

Technical Field

[0001] This utility model relates to the field of continuous thin film processing technology, specifically a tension calibration device for a foil production machine. Background Technology

[0002] Tension rollers and tension control systems are widely used in the production of continuous films such as paper, textiles, plastic films, and copper and aluminum foil to ensure stable and continuous film transfer in the production system. Tension calibration of the tension rollers and tension control system is required during initial commissioning of production equipment, transitions to different film specifications, and after prolonged use of the equipment.

[0003] Traditional tension calibration methods involve using a long cable that travels along the film transport path, with a rated weight suspended at the end of the cable to apply a force to the tension roller. The tension roller is connected to a tension control system, which displays the tension value in the production equipment's adjustment window. Adjustments to the relevant parameters in the tension control system are then made to perform tension calibration.

[0004] Traditional tension calibration methods require threading, which is cumbersome; moreover, the tension calibration values ​​depend on the mass of the suspended load each time, resulting in discontinuous values ​​that cannot meet the actual needs of customers. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a tension calibration device for a foil production machine that eliminates the need for threading and enables continuous tension calibration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A tension calibration device for a foil production machine includes a shaft head clamping component, a connecting component, a support component, and an angle adjusting component. The shaft head clamping component and the support component are respectively installed at both ends of the connecting component. The angle adjusting component is disposed at one end of the support component. The angle adjusting component is installed on the frame of the foil production machine and is used to adjust the rotation angle of the connecting component. One end of the shaft head clamping component is pressed against the side wall of the tension roller shaft head and is used to adjust and monitor the pressure applied to the tension roller shaft head.

[0007] Preferably, the support member includes a threaded guide rod and two locking nuts; one end of the connector is provided with a locking hole, the threaded guide rod passes through the locking hole, and the two locking nuts are respectively installed on both sides of the locking hole through the threads on the threaded guide rod, so as to adjust and fix the position of the threaded guide rod in the locking hole.

[0008] Preferably, the angle adjusting component includes a rotating adjusting base and a rotating mechanism; the rotating adjusting base is placed on one side of the tension roller shaft head; the rotating mechanism is installed inside the rotating adjusting base; one end of the support component is fixedly connected to the rotating mechanism; the rotating adjusting base is provided with an arc-shaped adjusting groove, the axis of the arc-shaped adjusting groove is in the same straight line as the axis of the tension roller; the rotating mechanism is provided with a limiting part, one end of which is movably placed in the arc-shaped adjusting groove.

[0009] Preferably, the shaft head clamping component includes a pressure detection rod, a clamping mechanism, a pressure sensor, a universal joint, and a slider; the upper end of the pressure detection rod is mounted on the connector; the clamping mechanism is located in the middle of the pressure detection rod; the pressure sensor is connected to the lower end of the clamping mechanism; the universal joint is mounted on the lower end of the pressure sensor; the slider is mounted on the lower end of the universal joint, and the slider is used to clamp the tension roller shaft head.

[0010] Preferably, the slider is configured to conform to the semi-circular arc shape of the end of the tension roller shaft.

[0011] Preferably, the connector is provided with a mounting hole; the upper part of the pressure detection rod is mounted in the mounting hole via a bearing.

[0012] Preferably, the shaft head clamping component further includes a locking bolt; the locking bolt is installed on the connecting component and is used to lock the circumferential rotation of the pressure detection rod.

[0013] Preferably, the connecting member is a linkage mechanism.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The angle adjustment component employs a design that combines a rotating adjustment base with a rotating mechanism. The rotating axis of the mechanism is coaxial with the tension roller, and the rotating adjustment base features an arc-shaped adjustment groove, allowing for precise adjustment of the overall angle of the device to perfectly align with the direction of the resultant tension force of the tension roller. Simultaneously, the shaft head clamping component is equipped with a universal joint and a semi-circular slider, ensuring a tight fit against the tension roller shaft head and adapting to the contact angle. The pressure detection rod, mounted via bearings, allows for flexible angle adjustment. This multi-layered structure ensures the stability of the pressure application direction and the force contact. The shaft head clamping component integrates a clamping mechanism and a pressure sensor. Rotating the clamping mechanism allows for continuous adjustment of the pressure applied to the tension roller, while the pressure sensor provides real-time feedback. This replaces the traditional method of suspending and fixing a heavy object, overcoming the limitations of discrete tension calibration values ​​and meeting the precise calibration requirements of different tension ranges. The axial position of the linkage mechanism can be quickly adjusted via a threaded guide rod and double locking nuts. The circumferential rotation of the pressure detection rod is locked by locking bolts. The entire installation and adjustment process eliminates the need for threading, simplifying the calibration process and reducing operational steps and manpower. The adjustable position of the support components, the adjustable angle of the angle adjustment components, and the adjustable angle of the pressure detection rod enable the device to adapt to tension rollers and tension control systems of different specifications. Moreover, the overall structure is installed on the foil production machine frame without the need for major modifications to the production equipment. It can be widely used in various continuous film production scenarios such as paper, textiles, plastic films, and copper and aluminum foil. Attached Figure Description

[0021] In this embodiment, the shaft head clamping component includes a pressure detection rod 6, a clamping mechanism 4, a pressure sensor 3, a universal joint 2, and a slider 1.
