Abstract

A device for loading of bulk materials into valve bags relates to packing equipment in the agro-industrial, building and chemical branches of economy.

Description

The useful model belongs to the packaging equipment and can be used in agro-industry, construction, chemical branches of the economy, as well as in enterprises that carry out packaging of loose materials.

A well-known device for loading loose materials into valve bags (Patent of Ukraine Me 1696 MPK B 6581/001.

The device includes a hopper, a loading weighing device, an automation system, the disadvantage of the device is its low productivity, as well as the fact that it does not exclude technological process disruption (channel clogging) due to the presence of a valve on the loading device.

The closest to the proposed one is a device for loading loose materials into valve bags (Patent

Ukraine Mo 46786 C2 IPK 8658 1/181.

The device includes a hopper, a valve, a material pipeline, a supply loading and weighing device, an automation system.

The disadvantages of the device are its low performance and accuracy of mass dosing, increased energy consumption, and the fact that it does not eliminate the possibility of air entering the valve bag after the flow of loose material from the blade of the supply device, which does not make it possible to ensure complete filling of the valve bag.

The useful model is based on the task of increasing productivity, accuracy of mass dosing, reducing energy consumption, increasing the filling of the valve bag with loose materials by continuously feeding the material into the valve bags, accurately cutting off the flow of loose material in the loading nozzle at the end of the bag loading process, reducing the friction area of the loose material in delivery device, eliminating the conditions for air entering the bag by continuously filling the volume of the delivery device with loose material in the location area, discharge nozzles.

The task is solved by the fact that in the device for loading loose materials into valve bags, which contains a hopper, a valve located at the outlet of the hopper, a material leakage regulator, a flow divider, material pipelines, a rotary-type supply device, which includes a housing with unloading nozzles and the rotor, the loading and weighing device, the automation system, according to the useful model, the output ends of the material pipelines are located in the area of the discharge nozzles of the supply device, and the body of the supply device is installed with the ability to perform reverse-rotational movements in such a way that in the extreme positions the directions of the channels of the discharge nozzles coincide with the directions of one of the channels of loading devices, which are made in the form of tees with an input channel and loading nozzles, which are branches of the input channel.

Such design differences of the device make it possible to increase productivity, as the bulk material continuously enters the bags without blocking the channels of the loading nozzles during the period of replacing the bags, to increase the accuracy of mass dosing in the bags by clearly cutting off the bulk material coming from the discharge nozzles into the channels of the loading nozzles when turning the housing of the supply device, to reduce the energy consumption, and also to increase the filling of the valve bag with loose material by eliminating the conditions for air to flow into the bag, which is achieved by continuously filling the volume of the supply device with loose material in the area of the discharge nozzles.

The proposed device is explained by diagrams, which show: in Fig. 1 - device, general view; on

Fig. 2 - section A - A in Fig. 1. in Fig. 3 - view B in Fig. 1.

The device contains a hopper 1, a valve, a leak regulator, a flow divider, material pipelines 2, a supply, loading and weighing device, an automation system (not shown in the drawings).

The valve includes the lever 3, which is hingedly mounted on the frame 4, the damper 5, which is rigidly mounted on the lever Z and enters the slot made at the exit from the hopper 1. The valve is actuated by an electromagnet 6 (opening the opening of the hopper) and a spring 7 (covering the hopper opening).

The leakage regulator includes a body 8, in which two upper hanging leaves 9 are hinged, the position of which is adjusted by screws 10.

The flow divider includes the body 11, which is made in the form of a tee, containing the inlet channel "a" and the branch "b", the inner walls of which form the divider "c".

Material pipelines 2 are fixed on branches "b".

The delivery device includes a housing 12 with discharge nozzles 13, a rotor 14, which includes a hub "g" and blades "d" and is mounted on the shaft of an electric motor 15.

The housing 12 is mounted on the shaft of the electric motor 15 with the help of a bearing 16, the housing 12 rests through the balls 17, which are inserted in the pockets made in the housing 12, on the base plate 18, which has a suitable groove for the movement of the balls 17 and is rigidly connected to the frame 4 devices.

The rotation of the housing 12 is carried out by electromagnets 19 and 20, which are rigidly fixed to the frame 4 and alternately act on the lever 21, which is rigidly fixed to the housing 12. The output ends of the material pipeline 2 are located in the areas where the output nozzles 13 are located.

The loading devices 22 are made in the form of a tee, in the input channels of which discharge nozzles 13 are included.

Devices for holding bags 23 are mounted on the branches of tees "zh" and "3", and the tees themselves are rigidly installed on the frame 24 of the weighing device.

The weighing device includes a frame 24, which with the help of two levers 25, which together with the frame 4 and the frame 24 forms a parallelogram, is attached to the frame 4, while the levers at both ends have a hinged connection and weights 26.

Platforms for bags 27 are mounted on the frame 24. The device works as follows:

The valve bags are installed on the branches "z" and "z" of the loading devices 22 and the platform for the bags 27. The automation system is turned on, devices for holding the bags 23 press the valve bags to the branching nozzles. Under the action of the electromagnet 15, the housing 4 of the supply device is in such a position that the loose material can enter one of the channels of the loading devices 22. The electromagnet 6 rotates the valve, the damper 5, which is opened by the outlet of the hopper 1, performs free flight in the channels of the leak regulator, the divider flow and after interaction with the flow divider "v" enters the material pipelines 2, from which it enters the area of the discharge nozzles 13 of the supply device, where the blades "d" of the rotor 14 are directed through the channels of the discharge and loading nozzles into the valve bags.

When the valve bag is filled, the force of the frame 24 on the weights 26 increases.

When the required weight is reached, according to the signal of the automation system, the electromagnet 20 is turned on (the electromagnet 19 is turned off), under the action of which the body 12 is rotated. The material begins to flow into the second bags.

At the same time, the device for holding the bags 23 releases the first bags and they go down from the loading nozzles and platforms for the bags 27.

New bags are installed in the vacated places.

Then, the cycle of the device is repeated when the second bags are filled. 7 one 2 r 8. in nIA--- b M I 77 she 23 z Ch zh i k sinya 4 tlu" i SU yslo 2 Dedich t b-y | This t She vi (ШЧI shk In -
