Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described below with reference to the accompanying drawings and examples.

[0017] Such as figure 1 with figure 2 As shown, the present invention discloses an unwinding device with automatic deviation correction function, which is arranged at the front end of the emery cloth slitting machine, and is used to release the emery cloth at a uniform speed. Wherein, the unwinding device includes an abrasive cloth placing frame A510, an unwinding support rod A520 for supporting the abrasive cloth roll, and a deviation correcting device A530 that is transmission-connected with the abrasive cloth placing frame A510 and adjusts the offset. The deviation correcting device A530 is fixed on the frame, and moves left and right with the emery cloth placing frame A510. The unwinding support rollers A520 are arranged on the emery cloth ...

Abstract

The invention discloses an unwinding device with an automatic correction function. The unwinding device comprises an abrasive cloth containing frame, at least two unwinding supporting rollers used for supporting abrasive cloth rolls, and a correction device which is connected with the abrasive cloth containing frame in a transmission manner and used for regulating the offset. The correction device is fixed to a machine frame and drives the abrasive cloth containing frame to move leftwards and rightwards. The unwinding supporting rollers are arranged on the abrasive cloth containing frame and can rotate relative to the abrasive cloth containing frame. Gas expansion shafts used in the prior art are abandoned, the abrasive cloth rolls are supported by the two driven supporting rollers, and therefore feeding and discharging can be quite convenient and rapid. In addition, the abrasive cloth containing frame is arranged on a linear guide rail unit, driven by the automatic correction device to move leftwards and rightwards, and used for correcting abrasive cloth deviating from normal routes. The technical problems that by means of an existing unwinding device, abrasive cloth rolls can not be easily replaced and deviating abrasive cloth can not be automatically corrected are well solved.

Description

technical field [0001] The invention relates to the field of an automatic production line of a thousand-sheet wheel, in particular to an unwinding device with an automatic deviation correction function. Background technique [0002] Abrasive cloth slitting is the first process in the production of thousand-sheet wheels. A large roll of abrasive cloth can be divided into several rolls of small abrasive belts by a slitting machine. The traditional unwinding device of the slitting machine adopts the air expansion shaft method, and the air expansion shaft passes through the emery cloth roll, and then puts it on the shelf and locks it. Because the emery cloth roll is relatively heavy, it is not easy to put it on the shelf after inserting the air expansion shaft, and the replacement efficiency is low; in addition, the locking of the emery cloth roll is limited to the radial direction, and the axial direction can still deviate left and right, resulting in the left and right sides o...
