Description

Technical Field

[0001] The utility model relates to a feeding shaft, in particular to an online synchronous adjustment mechanism for the feeding shaft, and belongs to the technical field of product die-cutting and feeding. Background Art

[0002] In the die-cutting industry, the bending shaft is installed on both sides of the die-cutting station frame to guide or press the raw material belt, finished product belt or waste belt entering and leaving the die-cutting station. There are strict requirements for product warping during the die-cutting process. It is necessary to adjust the feeding angle of the bending shaft and the belt to change the material feeding position, so as to complete the guiding or pressing of the belt.

[0003] A known auxiliary bending shaft device for adjusting the angle (Announcement No.: CN115648326A) is described as "an auxiliary bending shaft device for adjusting the angle, comprising a bending shaft assembly, which comprises a feeding bending shaft, two side frames, and a fixed shaft, one end of the two side frames is connected by the fixed shaft, the two side ends of the fixed shaft are convex, and are used to be pivotally connected to the corresponding production line frame, and the other end brackets of the two side frames are fixedly connected to the feeding bending shaft; a supporting base, which comprises an upper plate frame and a lower plate, and the front and rear ends of the upper plate frame are respectively provided with lower convex connecting plates, and the lower convex connecting plates are respectively fixedly connected to the lower plate to form an adjustment installation cavity ; and an angle adjustment component, which includes a transmission frame, two adjustment columns, and a driving body. The transmission frame includes a connecting cross plate and triangular oblique blocks on both sides. Corresponding triangular oblique blocks are arranged on both sides of the length direction of the connecting cross plate. The lower end of the adjusting column is supported on the upper surface of the lower plate or the corresponding position of the inclined surface of the triangular oblique block. When it is found that the height of the feeding bending shaft needs to be adjusted at a small angle, the driving body is driven to drive the triangular oblique block to move toward the adjusting column, so that the lower end of the adjusting column is displaced relative to the inclined surface, thereby adjusting the height of the feeding bending shaft; the height position of the feeding bending shaft can be adjusted without stopping the machine, thereby ensuring the continuous production of the production line.

[0004] The existing feeding shaft cannot monitor its motion state during operation and cannot clean the dirt on the surface of the feeding shaft in time, resulting in an error in the distance between the feeding shaft and the material. Therefore, an online synchronous adjustment mechanism for the feeding shaft is proposed. Utility Model Content
