Description

Technical Field

[0001] The present invention relates to the field of clock and watch parts processing, and particularly relates to an automatic packaging and needle cutting integrated machine. Background Art

[0002] The rough blank of the watch needle is an intermediate product for automatically preparing the watch needle. It is continuously stamped and sheared on a long strip of metal tape to form a rough blank tape with multiple watch needles. After subsequent processing, the rough blank tape becomes a watch needle tape to be sheared. At this time, needle cutting is required. There is no special needle cutting equipment in the prior art, and needle cutting mostly relies on manual operation, with low efficiency, high labor cost, and unstable quality.

[0003] After needle cutting, because the watch needle is a slender object, the prior art cannot solve the problem of accurate quantitative packaging of such objects without damaging their appearance. It can only be packaged manually, with relatively low efficiency. Summary of the Invention

The structure of the automatic packaging and needle cutting integrated machine is scientifically and reasonably designed. The automatic needle cutting and packaging are made into an integral structure, and the watch needles can be packaged while cutting.

Multiple groups of tensioning mechanisms are also arranged on the front side of the workbench to tension and change the direction of the film.

[0032] The working process of the present invention is as follows: The watch hand belt to be cut is conveyed by external power and cut into individual watch hands.

[0033] By controlling the rotation speed of the speed - regulating motor, the moving speed of the needle belt is controlled. The needle belt moves upward through the material supporting surface to the positions of the upper knife group and the lower knife group. The motor drives the upper knife group and the lower knife group to rotate synchronously through the transmission mechanism to cut the watch hands on the watch hand belt. The cycle of the speed - regulating motor's pause is set to control the number of watch hands falling each time the needles are cut;

[0034] At the same time, the film feeding motor is started, driving the film to enter the longitudinal sealing mechanism through the tensioning mechanism for longitudinal sealing. The longitudinally sealed film sleeves the lower part of the round tube of the bag - forming device. The lower film - pulling driving shaft and the film - pulling driven shaft drive the friction wheels to apply tension to the longitudinally sealed film, keeping it in a tensioned state and moving it towards the transverse sealing mechanism. The bottom of the longitudinally sealed film is transversely sealed by the transverse sealing mechanism to form a film bag. At this time, the watch hands cut in one cycle fall into the film bag sealed at the bottom. The film bag continues to move downward, is sealed by the transverse sealing mechanism, and then is cut by the cutting mechanism, thus completing the packaging of a small package of watch hands through one cycle.

[0035] The present invention integrates automatic needle cutting and packaging into an overall structure, and can complete the packaging of watch hands while cutting the needles. At the same time, it solves the problems of automatic cutting and automatic packaging of watch hands in the prior art, achieving two goals with one action.

[0036] The present invention has high needle - cutting precision and low defective rate, can improve product quality, and has accurate packaging quantity and high automation degree, which can effectively reduce production costs. Description of the Drawings
