The invention relates to an automatic weighing device of electric welding rods, which is characterized by mainly comprising a machine frame, a feed shaft mechanism, a step-by-step feeding mechanism and a weighing assembly mechanism, wherein the feed shaft mechanism, the step-by-step feeding mechanism and the weighing assembly mechanism are connected to and fixed on the machine frame in turn; the step-by-step feeding mechanism mainly comprises conveying belts, circle-arc tooth synchronizing wheels and a motor reducing mechanism; the front and back parts of the machine frame are connected with a bearing block; belt pulleys are connected on front and back parallel conveying shafts of the bearing block by using keys, and are sleeved with the parallel conveying belts; the machine frame in front of the conveying belts is provided with a bearing block which supports a synchronous axle; the circle-arc tooth synchronizing wheels are connected to the synchronous axle by using keys; and the conveying shafts and the synchronous axle are driven by belts and are connected with the motor reducing mechanism. The automatic weighing device of the electric welding rods has the advantages that: because a sensor is adopted for accurate calculation and under allowance package is adopted, each production line can 'pack more than' 50 tons of the welding rods which value RMB 250,000 for an enterprise for one year; and the economic benefit is significant.
Description
Technical field
The invention belongs to meausring apparatus, relate in particular to a kind of welding electrode poidometer that is connected with the welding electrode production line terminal.
Background technology
At present, domestic welding electrode demand cumulative year after year.The production scale of welding electrode, production efficiency have all had large increase, and for example bridge group and Jinqiao Group are two big welding electrode manufacturing enterprises of Tianjin maximum, and each group all has more than 60 production line, and every production line output every day is about 15 tons.For a long time, welding electrode production line terminal packing is still taked hand-filling.Promptly, the welding rod that production line rolls off the production line fast is stacked on the production line tail end, by workman (most for woman worker) expertly with the hands pinched be put into finish weighing on the platform scale after, with the hands pinched rapidly in the packing box that another sacker that packs into hands, neat through the real arrangement of wholesale, give following sacker again and seal, check, case, put in storage, every production line per tour has six workmans to finish, and the sacker of enterprise as bridge, Golden Bridge is with regard to people more than 1000.Because both hands are in " transportation " that do not stop, labour intensity is very big, and the workman often needs by turns.But owing to be simple manual labor, sacker's wage income is on the low side again, and along with the continuous improvement of economic condition, the recruitment cost increases substantially, and personnel are run off seriously, and this packing post recruitment is more and more difficult.This kind welding electrode packing present situation is compared the weighing that the key that bottleneck occurs is welding electrode with the modern streamline of welding electrode.Application number: 87202320 disclose a kind of welding electrode automatic weighing machine, and its structure is by framework, importation, quick transport portion, checks part, photoelectric counting mechanism, grouping transport portion, rocking bar and topworks partly to constitute at a slow speed.This equipment be with welding electrode after automatic drying line cooling, utilize the method for velocity contrast, make that the welding electrode on the conveying belt becomes rarefaction state, a gap is promptly arranged between the welding rod, again by the photoelectric counting device, welding rod is monitored counting.Export a pulse signal when counting reaches a certain value (each packaging unit is every group of quantitative value that comprises welding rod, and the franchise of welding electrode is less), make the electromagnetic switch valve events, compressed air-driven topworks divides into groups welding rod.Thereby reach the purpose of automatic weighing.Welding electrode after the grouping is packed again.
This equipment can not be connected with the welding electrode production line terminal.Facts have proved that weighing is not accurate enough, can not reach ministerial standard, so can't promote the use of.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, a kind of welding electrode poidometer is provided, can be connected, automatically Weighing with the welding electrode production line terminal, for realizing that fully automatic electric electrode packaging production line lays the foundation, and thoroughly changes the backward situation of welding electrode hand-filling.
The present invention for achieving the above object, be achieved through the following technical solutions, a kind of welding electrode poidometer, it is characterized in that: mainly by frame, the pan feeding axis mechanism, the substep feed mechanism and the assemble mechanism of weighing constitute, described pan feeding axis mechanism, substep metering mechanism is connected successively with the assemble mechanism of weighing and is fixed on the frame, described substep feed mechanism is mainly by feed belt, the circle-arc tooth synchronizing wheel, motor reducer constitutes, be connected with bearing seat before and after the described frame, be linked with belt pulley on the parallel transmission shaft before and after the bearing block support, the feed belt that the belt pulley socket is parallel to each other, methods, rack is provided with bearing seat before the feed belt, bearing block support has synchronous wheel shaft, keyed jointing circle-arc tooth synchronizing wheel on the synchronous wheel shaft, described transmission shaft is connected by belt gear and with motor reducer with synchronous wheel shaft.
The described assemble mechanism of weighing mainly is made of weight sensor, weighing bucket, dropproof postive stop baffle, described weighing bucket is fixed on the frame by fixed head, described weight sensor is connected with frame by support post, affixed dropproof postive stop baffle on the described weighing bucket sidewall.
Beneficial effect: to increase economic efficiency, GB requires in the deviation of weight 1% by accurate metering, owing to adopt sensor accurately to measure, takes the allowance below nominal size packing, and annual every line can go out 50 tons of welding rods for enterprise's " many packings ", is worth 250,000 yuan.Remarkable in economical benefits.
