Abstract

The utility model relates to a microscale material feeding machine which comprises a machine frame, a motor arranged on the machine frame, a material bucket and a conveying device, wherein, the conveying device is composed of two belt wheels, a conveyer belt arranged on the belt wheels and a conveying cylinder composed of a shell body. The belt wheel which is arranged on a bracket is connected with a motor by a belt, a plurality of quantitative slots are processed on the conveyer belt, a material feeding opening of the material bucket is provided with a scraping plate, and the lower edge of the scraping plate is appressed with the conveyer belt. The utility model has the advantages of accurate feeding amount control and large regulating amplitude. Because materials are arranged in the quantitative slot, the materials are free from any press in the process of conveyance, and additive which is in a loose state all the time is not easy to cohere. Therefore, the utility model is especially suitable for feeding materials with strong hygroscopic property and poor flowing property.

Description

A kind of micro-feeding machine

The utility model relates to a kind of feeding machine, especially relates to a kind of micro-feeding machine, can be used for industry trace such as powder process, chemical industry, food, feed and adds various powderies, granular material.

At present, the micro-feeding machine of using in the actual production is based on screw feeder, as the SWLL scroll feeder, TWLZ30 series oscillating feeder, the conveyor screw that spiral feeding machine keystone configuration is made up of barrel, transport tube, helicallobe, sprocket wheel, reducing motor, retardation controller etc. are formed.It is that the additive that will add is put into barrel, fall between the helicallobe of transport tube import from the discharging opening of barrel bottom, helicallobe rotates, additive is constantly pushed to discharging opening, add in the material of manufacturing line, this type of feeding machine has following several defective: 1, charging is wayward, and the interpolation error is big.Additive is to rely on the additive-treated oil deadweight to fall when barrel enters conveyor screw, the stronger additive of hygroscopic property is with good adherence of together, easily form cavity or caking in the time of on falling helicallobe, conveyor screw can't make additive be evenly distributed in the helicallobe after rotating into transport tube, cause the additive discharging inhomogeneous, addition and base of calculation error are bigger.2, bibulous additive adds difficulty.In the interpolation process, additive promotes because of the extruding that is subjected to helicallobe at conveyor screw, and additive easily is bonded on the helicallobe, not only influences spirochetal extruding and promotes, and additive is formed piece or is bonded on the blade not fall, and causes additive to add.3, the addition range of regulation is limited.Because conveyor screw and helicallobe typing are constant, the variation of addition can only be controlled by motor speed merely, because the restriction of the speed adjustable range of motor own, the addition setting range also is restricted.

The purpose of this utility model provides a kind of addition precise control, micro-feeding machine that range of regulation is big, makes it be particularly suitable for adding the additive of the strong free-running property difference of hygroscopic property.

For achieving the above object, the utility model adopts following technical scheme: a kind of micro-feeding machine, comprise frame, be contained in motor, hopper, discharging opening and feedway on the frame, feedway by two belt wheels, be contained in the load-transfer device on the belt wheel and the transport tube be made up of casing is formed, belt wheel is contained on the support and by belt and is connected with motor, be processed with some quantitative slots on the load-transfer device, hopper feed opening place is provided with scraper plate, and the scraper plate lower edge is close to load-transfer device.

The hopper top is added with seal cover cap, and seal cover cap is divided into two parts, and half is fixed on the hopper, and second half is a removable cover, has a reducing motor to be installed on the fixed cap, and reducing motor links to each other with hopper in-to-in rabble, has blade on the rabble.

The pulley support partial fixing that stretches out has a bevelled spring vibration sheet, and the termination of spring vibration sheet rides in the quantitative slot.

High speed agitator is equipped with at the discharging opening place, and it is made up of motor and branch shape rabble, and motor is contained in the casing outside, and branch shape rabble vertically is contained in the casing in-to-in belt pulley outside.

Because the utility model adopts the quantitative slot convey materials on the load-transfer device, after material dropped to quantitative slot from hopper, scraper plate was wipeed quantitative slot off, guaranteed that quantitative slot is full of additive, made the additive accurate measurement.Simultaneously, when quantitative slot turns to discharging opening, be subjected to the vibration of spring leaf, a small amount of additive that does not fall is also fallen after vibration, further guarantee the accurate of additive capacity.Because material in quantitative slot, is not subjected to any extruding in course of conveying, additive is in loose condition (of surface) always, is difficult for bonding, therefore is particularly suitable for adding the material of the strong free-running property difference of hygroscopic property.

Further specify the utility model below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is the structural representation of embodiment;

Fig. 2 is the birds-eye view of Fig. 1;

Fig. 3 is the enlarged drawing at Figure 1A place;

Fig. 4 is the enlarged drawing at Figure 1B place.

Embodiment: 16 are equipped with motor 15 on the frame, and motor 15 is connected with belt wheel 12 on being contained in frame by belt 14, and load-transfer device 17 is contained on two belt wheels 12, and processing is some on the belt wheel quantitative slots 1 of closely arranging and certain depth being arranged.The transport tube of being made up of housing 10 18 is housed on the frame, and hopper 3 is equipped with in the housing top, and the hopper feed opening is in a side consistent with defeated material direction and is provided with a scraper plate 9, and the scraper plate lower edge is close to load-transfer device 17.Hopper 3 tops are added with seal cover cap 19, and it is made up of two parts, and half is fixed on the hopper, and second half is a removable cover, and reducing motor 2 is installed on the fixed cap and with hopper in-to-in rabble 4 and links to each other, and has blade 20 on the rabble.Row's degree of dip is housed is 30-45 ° spring vibration sheet 11 in that part 8 places that stretch out on the frame of belt wheel 12 are installed, and the termination of each spring vibration sheet rides in the quantitative slot.High speed agitator is equipped with at discharging opening 21 places, and it is made up of motor 6 and branch shape rabble 7, and motor 6 is contained in housing 10 tops, and branch shape rabble 7 vertically is installed in the housing 10 in-to-in belt wheels outside, and distance can not be less than 2cm.

Its principle of work is: material is added from hopper top, tentatively stir by rabble, material drops in the quantitative slot on the load-transfer device afterwards, advance to the scraper plate place with load-transfer device, material is wipeed off the back by scraper plate and is continued to advance with load-transfer device, pulverized by high speed agitator after arriving the feed opening place, guarantee by the certain fineness feed.Simultaneously, the spring vibration sheet shakes the additive in the quantitative slot fall.
