Production equipment for noble metal chain and automatic chain collecting machine thereof

Abstract

The invention discloses an automatic chain collecting machine. The automatic chain collecting machine comprises a chain collecting frame which is used for storing chains and capable of adjusting the size of chain coils, a first sensor which is arranged at the first preset position on the first side of the chain collecting frame and used for outputting a first sensing signal when the chains are sensed, a second sensor which is arranged at the second preset position on the first side of the chain collecting frame and used for outputting the second sensing signal when the chains are sensed, and an electric control box which is connected with the first sensor and the second sensor and used for controlling the chain collecting frame and a chain weaving machine to start and stop according to thesensing signals of the first sensor and the second sensor. The invention further discloses noble metal chain production equipment comprising the automatic chain collecting machine. According to the automatic chain collecting machine, the production of noble metal long chains can be protected, the production efficiency and the product quality can be improved, and the production cost can be reduced; and meanwhile, the automatic chain collecting machine can be suitable for the long chains with different shapes and thicknesses, and can also be suitable for the chain weaving machines with different speeds.

Description

technical field [0001] The invention relates to the technical field of precious metal chain production, in particular to an automatic chain retracting machine. The invention also relates to a production equipment for precious metal chains with the automatic chain winding machine. Background technique [0002] The chain retracting equipment refers to the equipment for winding and storing long chains. At present, the commonly used methods are manual chain retraction and storage wheel chain retraction. [0003] Manual closing refers to: after the chain weaving machine has finished weaving the chain, let it be stacked naturally in the tray, and then arrange it by hand. Storage wheel chain collection refers to the use of two counter-rotating rollers as the feed device. In traditional chain collection equipment, the distance between the two rollers of the feed device is fixed and can only be picked and fixed. Thick and thin chains, when collecting too thick chains, the two rolle...

Problems solved by technology

Storage wheel chain collection refers to the use of two counter-rotating rollers as the feed device. In traditional chain collection equipment, the distance between the two rollers of the feed device is fixed and can only be picked and fixed. Thick and thin chains, when collecting too thick chains, the two rollers will over-squeeze the too thick chains, causing the chains to wear very seriously. When picking too thin chains, the thickness of the too thin chains is less The distance between the two rollers makes it impossible for a chain that is too thin to be clamped by the feeding device. Therefore, for each specification of the chain, it is necessary to configure a different chain closing device, which is a waste of resources and is prone to failure when the equipment stops running. break the chain

However, the disadvantages of manual chain closure are obvious. Not only is it labor-intensive and inefficient, but also it is easy to knot and tangle when closing the chain, which increases a lot of manpower and time costs; The chain weaving speed of the chain machine is different, and it is necessary to adjust the chain closing speed, which is troublesome. It cannot be adjusted according to the situation of the chain weaving machine in real time, and when the weaving chain breaks down or the weaving chain ends, it cannot automatically stop; at the same time, the wheel is used to close the chain. Difficult to tidy up

[0004] Therefore, how to avoid affecting the stability and safety of long chain production due to the fact that the traditional chain closing method cannot be adjusted in real time according to the chain weaving and chain closing situation is a technical problem that those skilled in the art need to solve at present.
