Automatic feeding device and jewelry wire cut-off machine comprising same

Abstract

The invention discloses an automatic feeding device and a jewelry wire cut-off machine comprising the same. The automatic feeding device comprises a base, a sliding block component and a pressing block component, wherein the sliding block component is connected with the base in a sliding manner; the pressing block component is fixedly connected with the base; the sliding block component comprises a sliding block body, a locking block, a feeding roller wheel, a first ejector rod and a second ejector rod; the locking block is arranged on the sliding block body; the feeding roller wheel is arranged at the feeding end of the sliding block body; the first ejector rod and the second ejector rod are arranged above the sliding block component; an inclined surface in pressure contact with the feeding roller wheel is arranged at the lower end of the first ejector rod; a locking position roller wheel in pressure contact with the locking block is arranged at the lower end of the second ejector rod; the pressing block component comprises a pressing block body, a pressing block and a third ejector rod; the pressing block is arranged on the pressing block body; the third ejector rod is arranged above the pressing block; and the lower part of the third ejector rod is in pressure contact with the pressing block. According to the invention, each feeding work period is accurate, the service life is long and the effect of convenience for maintenance is achieved. Jewelry wires can be cut off continuously and automatically, so that the production efficiency of material cutting is improved, the accurate procedure of material cutting is improved, and the raw materials for processing each piece of jewelry have the same size.

Description

technical field [0001] The invention relates to a feeding device for continuously feeding processed wires, more specifically an automatic feeding device and a jewelry wire cutting machine formed by the device. Background technique [0002] In the prior art, for the processing of jewelry and other metal products, many necklaces or bracelets are connected by many accessories, and many wires are used as raw materials. During the processing of wires, traditional manual jewelry cutting machines are needed to cut materials one by one. Because the raw materials of jewelry products are very expensive, jewelry processing machinery and equipment are not automated, and what generally adopt in the prior art is manual cutting. However, manual operation of cutting equipment is prone to accidents; not only the production efficiency is not high, resulting in different sizes and specifications, the controllability is complicated, and the labor cost is high, which leads to an increase in the ...

Problems solved by technology

Because the raw materials of jewelry products are very expensive, jewelry processing machinery and equipment are not automated, and manual cutting is generally used in the prior art.

However, accidents are prone to occur when manually operating the material cutting equipment; not only the production efficiency is not high, resulting in different sizes and specifications, the controllability is complicated, and the labor cost is high, which leads to an increase in the production cost of jewelry products
