Abstract
The invention discloses an alarm for safe lead insertion. The alarm comprises a detection input end (6) which is connected with a programmable logic controller, wherein the detection input end is connected with two ends of a low-melting point spring (3); a lead (2) penetrates through the low-melting-point spring; and when the lead is cut and heated and burns, the low-melting-point spring is heated and fused, the detection input end is disconnected and sends a signal to the programmable logic controller, and the programmable logic controller automatically cuts off power of the whole production line and sends an alarm signal. The low-melting-point spring through which the lead penetrates is connected at the detection input end which is arranged in the lead cutting process, so that when the lead is cut and burns, the programmable logic controller can cut off working power of the lead-cutting and lead-inserting production line automatically and send the alarm signal in time; and burning failure of the lead is eliminated in time before the lead insertion and the lead-inserting production line work is continued, so that lead loss can be avoided, production efficiency is ensured, materials and electricity are not wasted, and the lead-inserting production cost is reduced.
Description
Technical field
The present invention relates to alarm, especially relate to the plug in alarm that draws of a kind of fireworks and firecracker safety.
Background technology
Insert that to draw be a important procedure during fireworks and firecracker is produced, it not only had been related to the fireworks and firecracker product quality, but also had been related to production efficiency and production safety.At present, big-and-middle-sized fireworks and firecracker manufacturing enterprise mostly adopts the mechanization streamline to insert to draw, not only improved fireworks and firecracker production efficiency, and improved product quality.Because lead-in wire is a kind of combustible of low ignition point, insert in the lead-in wire shearing of drawing in mechanization, especially when going between at the higher environment down cut of operating temperature, lead-in wire is heated easily and burns, in the mechanization pipelining, this problem only depends on hand inspection to be difficult in time find before slotting drawing, can only draw operation and could find after finishing inserting, thereby can cause and insert derivation runoff yield waterline non-productive work, not only reduced to insert and drawn efficient, and waste material and electric energy, increase slotting derivation and produced cost.
Summary of the invention
For the slotting problem that exists in the operation of drawing of mechanization streamline in the above-mentioned prior art, the invention provides and a kind ofly be arranged on mechanization and insert and to draw on the production line, when shearing lead-in wire generation burning, autoshutdown is inserted and is drawn the production line power supply immediately, and sends simultaneously the alarm for safe lead insertion of alarm signal.
The technical scheme that the technical problem to be solved in the present invention is taked is: described alarm for safe lead insertion is arranged on to insert and draws production line and cut and draw before the operation, it comprises the detection input that links to each other with programmable logic controller (PLC), described detection input is connected with the low melting point both ends of the spring, described lead-in wire passes the low melting point spring, when the generation burning is heated in the lead-in wire shearing, the low melting point spring is heated to fuse to make and detects the input disconnection, detect input and send signal to programmable logic controller (PLC), the programmable logic controller (PLC) autoshutdown is inserted and is drawn the production line power supply and send simultaneously alarm signal.
The present invention is connected with the low melting point spring that can pass lead-in wire owing to cut the detection input that draws the operation setting at the slotting lead-in wire that draws on the production line, in case cut when lead-in wire and to draw when burning takes place, the programmable logic controller (PLC) immediately whole slotting derivation product lineman of autoshutdown is made power supply and is in time sent alarm signal, draw front timely discharge lead-in wire combustion failure inserting, carrying out streamline cuts to draw to insert and draws operation again, both can avoid the lead-in wire loss, can guarantee again the stable and production efficiency of production safety, can not waste material and electric energy again, can not increase yet and insert derivation product cost.
Description of drawings
Fig. 1 is the structural representation of invention.
In the drawings, 1, send pick-up roll 2, lead-in wire 3, low melting point spring 4, cut and draw cutter 5, paper web 6, detect input.
The specific embodiment
In Fig. 1, described safety is inserted and to be drawn alarm and be arranged on lead-in wire and insert and draw cutting of production line and draw before the operation and (to insert and to draw production line and comprise cutting and draw, insert and draw, operations such as filling), it comprises the detection input 6 that links to each other with programmable logic controller (PLC), described detection input is connected with low melting point spring 3 two ends, described lead-in wire 2 is exported under the effect of sending pick-up roll 1, the end that goes between passes low melting point spring 3, described low melting point spring is not higher than 140 ℃ wire with fusing point and makes, described wire is soldering silk or slicker solder barium alloy silk, be provided with to cut and drawing cutter 4 near position, low melting point spring right side, the lead-in wire 2 that cuts off is inserted in the paper web 5, finish to insert and draw work, when lead-in wire is heated the generation burning when shearing, the instantaneous temperature that is produced can reach more than 200 degrees centigrade, low melting point spring near lead-in wire, the particularly middle fusing of being heated easily of low melting point spring, the detection input that existing low melting point both ends of the spring is linked to each other disconnects, detect input and disconnect and send signal to programmable logic controller (PLC) immediately, programmable logic controller (PLC) (PLC) is cut automatically and is drawn and slotting drainage waterline working power and send alarm signal.Specific embodiment, at present the fireworks and firecracker lead-in wire has two kinds, and a kind of is that common lead-in wire, another kind are safety leads, and the low melting point spring length that common lead-in wire uses is that 3 centimetres, diameter of bore are 3mm, is spaced apart 1mm, and wire diameter is 1mm; The low melting point spring length that safety lead uses is that 3 centimetres, diameter of bore are 5mm, be spaced apart 2mm, the wire wire diameter is 1mm, two kinds of all available low melting point tin welding wire manufacturings of spring, the tin welding wire striking point is 140 degrees centigrade, and be 70 degrees centigrade with the low melting point spring striking point of slicker solder barium alloy silk manufacturing, the low melting point spring that therefore uses slicker solder barium alloy silk to make is better.
Claims (2)
1. safety is inserted and is drawn alarm, it is arranged on to insert draws production line and cuts and draw before the operation, it is characterized in that: described safety is inserted and to be drawn alarm and comprise the detection input (6) that links to each other with programmable logic controller (PLC), described detection input is connected with low melting point spring (3) two ends, described lead-in wire (2) passes the low melting point spring, when the generation burning is heated in the lead-in wire shearing, the low melting point spring is heated to fuse to make and detects the input disconnection, detect input and send signal to programmable logic controller (PLC), programmable logic controller (PLC) cuts out automatically to insert and draws the production line power supply and send alarm signal simultaneously.
