Description

Punching needle guide mechanism of automatic paillette pattern arranging machine with superfine punching needle

Technical Field

The utility model relates to a clothing decoration processing machinery, in particular to a punching needle guide mechanism of an automatic paillette pattern arranging machine with an ultra-fine punching needle.

Background

The decorative paillette patterns usually used for decoration are composed of various colors and shapes. The automatic paillette arranging machine in the prior art can automatically fill and combine decorative paillettes with various colors and shapes according to the design drawings of designers, and finally paste the decorative paillettes to the design parts of clothes to manufacture various beautiful patterns.

Before the decorative paillette is processed, the original strip-shaped base material (base band) is generally wound on a disc to be used as a raw material of an automatic paillette pattern arranging machine, the raw material is punched and then pasted on a drawing, and then the paillette is attached to a dress design position.

The published patent application for an automatic paillette decorating and arranging machine (application number: 201810341473.6) provides a scheme that a round hole is not arranged in the middle of a paillette, so that the paillette area is reduced. The invention discloses an automatic decorating paillette arraying machine, which consists of a rack, a control device, a color changing driving device, a paillette stamping device and a positioning device, wherein the color changing driving device is arranged on the rack and used for driving the paillette stamping device to horizontally and linearly move; the paillette stamping device can be provided with a plurality of groups to realize the simultaneous processing of a plurality of drawings, and comprises six feeding devices, six punching needle guide mechanisms and one stamping device; the feeding device comprises a belt disc and a bracket; the belt disc is arranged above the bracket, the bracket base is provided with a punching needle guide mechanism, and a punching device is arranged above the punching needle guide mechanism; the paillette stamping device is connected to the rack and slides along a guide rail on the rack; the positioning device is arranged above the color changing driving positioning device and used for positioning the color changing driving device.

The stamping device consists of a transmission mechanism, a connecting arm and a connecting rod; the upper part of the stamping device is connected with the frame, and the lower part of the stamping device is connected with the stamping needle guide mechanism; the punching device transmits power to the punching needle guide mechanism through longitudinal reciprocating linear motion.

The punching guide mechanism consists of a punching needle, a punching needle seat, a guide rod, a pressure spring, a punching die base, a concave die seat and a concave die; the punch needle seat is connected with the punch needle base through the guide rod, and the spring is used for buffering. The punching needle seat is provided with a punching needle positioning hole for installing a punching needle.
