Description

Longitudinal position control mechanism of automatic bending machine for curved surface of lapel former

Technical Field

The utility model relates to an automated production equipment especially relates to a vertical position control mechanism of automatic bending machine of lapel former curved surface.

Background

In a vertical bag-making, filling and packaging machine, a lapel former is a key component. The design parameters of the lapel former are different due to different bag types and sizes of packaged products, and even for the packaged products with the same bag type size, the design parameters of the lapel former are different due to different specifications and sizes of the vertical bag-making, filling and packaging machine and different positions of the lapel former in the machine, and the design parameters are changed greatly, so that the curved surface of the lapel former is changed greatly.

When the lapel former is manufactured, if the three-dimensional lapel former is manufactured by adopting a material removing processing process of a numerical control machine or a material adding processing process of a three-dimensional printing technology, the requirements can be met technically. But the manufacturing cost is high, and the two processing technologies can hardly be widely adopted. At present, on a multi-row bag-making and filling packaging machine mainly for medicines or health care products of which the packaging objects are calculated by gram, a lapel former is mostly processed by a numerical control machine due to small size of the lapel former.

Most of lapel formers on the vertical bag-making, filling and packaging machines are manufactured by sheet metal technology, and the curved surfaces of the formers are formed by bending flat steel plates. Due to the characteristic of the curved surface of the shoulder of the lapel former, a mould which can meet the curved surfaces of various specifications does not exist for bending the curved plate of the lapel former. Therefore, industrially developed countries such as the United states, the United kingdom, the Japan and the like all adopt a manual production mode of workers with abundant production experience in the aspect of sheet metal manufacturing of lapel formers.

The lapel former is formed by combining a collar-shaped curved surface and a cylindrical surface. When the film is drawn on the surface of the former, the longitudinal direction and the transverse direction of the film are not extended or shortened at any position, so that the working curved surfaces of the collar-shaped curved surface and the cylindrical surface can be unfolded into a plane, namely an extensible curved surface, which is also the basic principle that a flat steel plate can be bent into the curved surface of the former by using a sheet metal process.

The collar-shaped surface consists of a space plane and two symmetrical space curved surfaces, the symmetrical space curved surfaces are called shoulder curved surfaces, and when the lapel former is manufactured by adopting a sheet metal process, the manufacturing difficulty is how to accurately bend a plane steel plate into the shoulder curved surfaces.

The shoulder curved surface is an expandable curved surface and is composed of one or more conical surfaces, the conical curved surface is formed by a straight line which is continuously moved around a fixed point, the straight line is mathematically a generatrix, and therefore the shoulder curved surface can be regarded as being composed of infinite straight lines formed by the generatrix at infinite positions. A typical method for manually bending the curved surface of the former at present is to cut a planar steel plate into a to-be-bent steel plate 1 ' with the shape as shown in fig. 3 according to a design drawing, print a plurality of straight lines in fig. 3 on the to-be-bent steel plate 1 ' of the steel plate as a mark line 2 ' by laser with small power, and allow a worker to bend the steel plate in the same direction at the reference line by using the mark line 2 ' on the to-be-bent steel plate 1 ' as a reference during bending; the desired shape after the segment-by-segment bending is the design shape, as shown in fig. 4. The precision and the left-right symmetry degree during bending depend on the experience of workers and the correction level after bending, and the manufacturing method has the problems of low working efficiency, low precision, symmetry and consistency of the manufactured lapel former and difficult quality guarantee.
