Detailed Description

The utility model will be further described with reference to the drawings and specific examples to aid in understanding the context of the utility model. The method used in the utility model is a conventional method unless specified otherwise; the raw materials and devices used, unless otherwise specified, are all conventional commercial products.

The utility model provides a film coiling anti-folding centering device, which is shown in figure 1 and comprises a centering clamping arm 2 and an adjustable clamping head 4.

Preferably, the whole device also comprises a driving mechanism, so that automatic centering or manual centering is realized, and the driving mechanism is provided with two movable ends which are respectively connected with the centering clamping arm 2. Further, the driving mechanism adopts a double-head screw 1, two screw nuts are used as movable ends and are respectively fixedly connected with the corresponding centering clamping arms 2, a sliding mechanism is arranged on a rack of the winding wire and used for limiting the circumferential position of the centering clamping arms 2, and the axial direction is driven by the screw nuts, so that the two centering clamping arms 2 synchronously move in opposite directions, and automatic centering is realized.

The centering clip arm 2 may be a long strip plate structure or a metal frame structure, and in this embodiment, a long strip plate structure is adopted, and two centering clip arms are respectively located at two sides of the winding wire. Each centering clamping arm 2 is transversely provided with a horizontal clamping rod 3. Because the rotation modes of the rollers are different, if the rollers are driven by the horizontal clamping rods 3, the horizontal clamping rods 3 can be designed to be in rotary connection with the centering clamping arms 2 through bearings; preferably, in this embodiment, the horizontal clamping bar 3 adopts a square metal pipe structure in consideration of the problem of support stability.

The end of the horizontal clamping rod 3 is provided with an adjustable clamping head 4 through a fastener. As shown in fig. 2, the adjustable chuck outer portion 401 is of a sleeve structure, and the tail end is detachably provided with a slope structure. Preferably, because different roller rotation driving modes are different, considering the situation that centering is needed to drive rotation, the installation hole on the inner side of the adjustable chuck 4 along the axis is also designed to be a square through hole and is used for being sleeved on the horizontal clamping rod 3, and the design can enable the adjustable chuck to express torque without additional components. Correspondingly, in order to improve stability, a locking screw 404 is further installed on the peripheral side surface of the adjustable chuck 4, so as to fix the horizontal clamping rod 3 and the adjustable chuck 4. The upper part of the locking screw 404 is correspondingly provided with a manual screwing handle, which consists of a nut 403 and a handle 402, and is convenient for manual installation. Further, in this embodiment, the slope structure is specifically an inclined metal plate 405, so that the metal plate is uniformly or non-uniformly distributed along the circumferential direction of the end surface of the adjustable chuck 4. Further, each side slope structure has two metal plates 405, and each metal plate 405 is located at two adjacent right-angle sides of the square through hole, and as shown in fig. 3, each metal plate 405 is inclined towards the medial axis direction and forms an angle a, which can be specifically determined according to the actual roller model. Through the asymmetric design, when the roller abuts against the inner diameter of the roller, the acting force is unevenly distributed, so that a small amount of deviation is generated between the axis of the roller and the axis of the horizontal clamping rod 3, and the spatial position of the axis of the roller can be correspondingly adjusted by means of the deviation, thereby correcting the deviation between the roller and the axis of the cooling roller and improving the parallelism. Correspondingly, because the end part of the metal plate 405 is designed to be fixed with the adjustable clamping head 4 through a fastener (not shown in the figure) such as a screw according to the construction condition of the front cooling roller and the model of the wind-up roller, the metal plate corresponding to the processing according to the actual condition can be installed and debugged.
