Description

A kind of screw feeder for packing scale
Technical field
The utility model relates to a kind of screw feeder for packing scale.
The utility model is applied to Weighing field.
Background technology
Feeding is that the important step of package metro-measuring, batching metering, measuring fixed amount is carried out in the fields such as grain and oil, feed, food, beverage, chemical industry, medicine, agricultural chemicals to material.In the feeding of package metro-measuring, conventionally adopt at present vibration feeder, belt feeding, impeller feeding, screw feed both at home and abroad, but most of screw feeder feeding that adopts.Particularly for granular material with to the particulate material of damaged no requirement (NR), adopt screw feeder feeding the most general.The screw feeder using both at home and abroad at present has simple helix feeding machine, double-screw feeder; There is the screw feeder that adopts formed objects, have the spiral material machine varying in size that adopts; These screw feeders are due to simple in structure, cheap, easy to use being greatly favored by consumers.But existing screw feeder requires when high or rate of feeding does not catch up with in measuring accuracy, or feeding precision out of reach, still can not meet operating needs on the feeding of packing scale, make user feel blemish in an otherwise perfect thing.Screw feeder of the present utility model adopts the quick feeding of king bolt, the accurate feeding of minor spiral speed change, the lower batch of material of the anti-blowdown of king bolt discharging and storage, level monitoring, greatly improved the deficiency that original screw feeder feeding exists, make the screw feeder manufactured by the utility model not only rate of feeding soon but also feeding accurate.
Summary of the invention
The purpose of this utility model is that a kind of screw feeder product of packing scale of fast accurate feeding is provided for the deficiency of the performance existence of existing packing scale screw feeder.
The technical solution of the utility model is: a kind of screw feeder for packing scale is characterized in that minor spiral drawing-in device, big or small spiral feeder apparatus independence tapping channel being housed and with the storage device of storage bin hopper at king bolt drawing-in device discharging section.
By such scheme: minor spiral drawing-in device is arranged on the bottom of king bolt drawing-in device discharging section, minor spiral drawing-in device is comprised of motor, casing, helicallobe, screw mandrel, the helicallobe of minor spiral drawing-in device adopts variable pitch structure from small to large at inlet point place, adopt independent variable speed motor to drive, the casing of minor spiral drawing-in device and the casing of king bolt drawing-in device can be made into integral body also can be separated to make of attaching parts and connect, and the motor of minor spiral drawing-in device and spiral can also can adopt coupler, gear, sprocket wheel, belt wheel transmission by direct-connection transmission.Size spiral feeder apparatus is provided with separately independently tapping channel, and king bolt drawing-in device tapping channel is under the gate sheet of storage bin hopper, and minor spiral drawing-in device tapping channel separates with storage bin hopper on storage bin hopper limit can independent discharging.At king bolt drawing-in device discharge end, be provided with the storage device with storage bin hopper, storage bin hopper, cylinder, backplate, gate sheet, guide plate wheel, signal switch that storage device feeds material by level detector, storage king bolt drawing-in device form, cylinder is contained in the casing lower outside of storage device, be connected with gate sheet, backplate is contained in the casing lower inside of storage device, and gate sheet is contained between backplate and guide plate wheel.
The utility model is with the positive effect that the screw feeder of domestic and international existing wrapping machine is compared: 1. its big or small double helix of big or small double-spiral structure using in the screw feed system of packing scale both at home and abroad is at present substantially isometric, minor spiral because of length long one be that difficulty manufactures little screw, the 2nd, long minor spiral easily produces when feeding that putty, discharging are smooth and discharging is uneven; Big or small double-spiral structure of the present utility model is arranged on the bottom of king bolt discharging section because of minor spiral, helix length is only 1/3~1/10 of original minor spiral length, can minor spiral be made enough littlely, helix length is little is difficult for knot arch when feeding, thereby makes the feeding of minor spiral energy continuous uniform greatly improve stability and the feeding precision of feeding.2. the big or small double-screw feeder using both at home and abroad is at present two spiral water placing flat or minor spiral is placed on to the side top of king bolt, will make like this screw feeder casing larger; Big or small double-spiral structure of the present utility model makes screw feeder volume little because of the bottom that minor spiral is arranged on king bolt discharging section, and low cost of manufacture, takes up room little, saves installing space.3. the screw feeder using on wrapping machine at present both at home and abroad at discharge end all without storage device, the utility model is provided with and prevents the storage device let out under material at king bolt drawing-in device discharge end, when feeding capacity reaches setting value, storage device closing gate prevents from letting out under material, in the time of closing gate, king bolt drawing-in device continues to feed the material of next scale, its material storing, in storage bin hopper, has so just been saved the feeding time of next scale material greatly; With its simultaneously minor spiral drawing-in device as requested the independent discharging of speed change feeding will greatly improve feeding precision like this.4. the utility model can prevent that because being provided with storage device blowdown from can store next batch of material again, so can king bolt drawing-in device be made greatlyr and can further improve rate of feeding.Adopt this storage device will make packing scale feeding time shorten 1/2~1/3, greatly improve the weighing speed of packing scale.5. the utility model, because being provided with storage device, improves the weighing speed of packing scale greatly, can economize out hopper, and packing scale height is reduced, and not only reduces investment outlay but also save setting height(from bottom).6. the screw feeder using on wrapping machine at present both at home and abroad at discharge end not only without storage device but also without level monitoring device, the utility model is provided with level monitoring device in storage bin hopper, king bolt drawing-in device feeding just stops feeding during to monitoring material position position, so just can completely not push bearing or knot arch causes fault because of storage bin hopper material.7. its large minor spiral of double-screw feeder using at present domestic and international wrapping machine is fed the material and all from a discharging opening, is flowed out, and storage bin hopper can not be set or storage bin hopper be set not in all senses; The material that its large minor spiral of the screw feeder using on wrapping machine of the present utility model feeds by two independently discharging opening flow out, when the accurate feeding of minor spiral king bolt fast feeding in storage bin hopper.This two independent discharge hole structures not only can be used on wrapping machine, also can be used on the occasion that other weighs feeding.
