A kind of production equipment of precious metal chain and its automatic chain closing machine

Abstract

The invention discloses an automatic chain retracting machine, comprising: a chain retracting frame for accommodating chains and capable of adjusting the size of the chain loop; A first sensor that outputs a first induction signal at a time; a second sensor that is arranged at a second preset position on the first side of the chain frame and is used to output a second induction signal when the chain is sensed; and the first sensor An electric control box connected with the second sensor for controlling the start and stop of the chain frame and the chain weaving machine according to the induction signals of the first sensor and the second sensor. The invention also discloses a production equipment of precious metal chains comprising the above-mentioned automatic chain winding machine. The above-mentioned automatic chain retractor can protect the production of precious metal long chains, and can improve production efficiency and product quality, and reduce production costs; at the same time, the automatic chain retractor can be applied to long chains of different shapes and thicknesses, and can also be applied to Speed ​​chain loom.

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.
