Description

Powder material blanking and conveying device

Technical Field

The utility model relates to the technical field of packaging machinery, concretely relates to powder material unloading, conveyor.

Background

Before the powder material is packaged, the powder material is generally required to be fed and conveyed.

The blanking mode is usually that a plate valve is installed in a blanking port of a hopper, and whether blanking is carried out or not and the blanking speed is controlled through the opening and closing of the plate valve and the opening degree. In the opening and closing process of the plate valve, powder materials can enter a gap between the plate valve and the feed opening, so that the smooth opening and closing of the plate valve are influenced; meanwhile, part of powder materials in the descending process are pushed to the front side face of the plate valve (the moving direction in the closing process of the plate valve is front) in the closing process of the plate valve, and when the feed opening is provided with the groove for containing the front side face of the plate valve, the part of powder materials are pushed to the position between the front side face of the plate valve and the groove, the sealing performance of the plate valve is influenced, and the plate valve is still provided with the powder materials after being closed to fall.

The conveying method generally adopts a conveying belt arranged below the feed opening, so that the powder material falling from the feed opening is conveyed to a packaging station to package the powder material. Powder materials can be extruded mutually and can not fall out from the feed opening in the blanking process, and a conveying belt can not receive all the materials due to deviation in the conveying process, so that the finally conveyed powder materials are reduced, and no powder materials are conveyed out.

Meanwhile, although the blanking speed of the powder material can be adjusted to a certain degree through the opening of the plate valve, the blanking speed is directly adjusted by opening the cross section area of the blanking opening, and the blanking speed is not only related to the opened cross section area of the blanking opening, but also related to parameters such as the height of the powder material in the hopper, the density of the powder material and the like, so that the adjustment mode of the blanking speed is inaccurate, and precise blanking cannot be realized.

divide the flitch 700, divide the flitch install in the feed opening, and divide the flitch to follow the cross section of feed opening arranges (specifically is the length direction of the face direction perpendicular to feed opening of branch flitch), divide the flitch to be located the top of fetching device, divide the flitch to have seted up branch material through-hole 710 (divide the material through-hole to be rectangular shape through-hole, the unloading that avoids powder material's mutual extrusion to cause is not smooth and easy, guarantees to get material efficiency and smart volume and gets the material), divide the material through-hole with rotate to divide the material through-hole below get the silo and correspond. Divide the flitch to divide into two-layer about with powder material, it is unable that the powder material of its top in getting the silo is not got into to divide the powder material of flitch below, a large amount of powder material's overdraft is born by the flitch promptly, avoid this pressure direct action to arouse the bending of getting the glassware behind the tripper, divide the flitch to bulge to the cavity of hopper, divide the flitch promptly to be the concave structure of epirelief, the structure of epirelief makes the downward pressure of powder material outwards disperse, the purpose of shunting powder material to the periphery of dividing the material through-hole has been played, avoid powder material all to extrude to divide the material through-hole to cause piling up, the jam in dividing material through-hole department. The concave structure makes the space which can contain the powder material be arranged between the material distributing plate and the material taking device, when the powder material is discharged too much, the material taking groove still has the outflow after being filled with the powder material, and the powder material which flows out can be contained in the space.

The utility model discloses still another embodiment can also include anti-blocking mechanism, anti-blocking mechanism includes gangbar 400, combination terminal 500 and vibrating motor 600, the gangbar rotationally installs in the frame between first rotational position and second rotational position, the gangbar has first end 410 and second end 420, be fixed with the combination terminal of being made by the conductor on the second end, vibrating motor is fixed in the outer wall of hopper, electric connection has first binding post 610 and second binding post 620 on vibrating motor's the power supply line, first binding post with the second binding post opens circuit,

because the unloading is not smooth and easy (powder material takes place in the hopper and has taken place part or totally blocked up), only accept partial powder material that conveyor belt work unusual (like the off tracking) leads to, even when not accepting the powder material, the gangbar rotates (along arrow T2 direction of fig. 3) to the second turned position, first binding post, second binding post all with combine the terminal electric conductance to lead to, vibrating motor is on-state, vibrating motor work, vibrating hopper, the problem that the unloading is not smooth and easy has been solved, and simultaneously, unloading is smooth and easy after observing vibrating motor work, vibrating motor still works for a long time, has reminded operating personnel to inspect whether conveyor belt normally works (like the off tracking etc.).

It should be noted that there are at least two (three are shown in the figure), and at least two fetching grooves are uniformly arranged along the peripheral side of the fetching device. Therefore, the material taking and discharging processes are continuous and stable, the impact of quick and slow discharging on the belt roller of the conveying belt is avoided, and meanwhile, the load of the second power unit for driving the belt roller to rotate is reduced (the discharging is too much in a short time, the output of the second power unit is required to be high, if the power is insufficient, the belt roller stops rotating, the second power unit stops working, the damage to the second power unit is caused, and if the second power unit is a motor, a coil of the motor is likely to be burnt out).

In addition, the width of the material taking groove is gradually reduced along the direction close to the axis of the material taking device. That is, the material taking groove is outwards open, so that the powder material can smoothly slide in, and the material taking efficiency is improved.

The conveyor belt may be arranged horizontally (as shown in fig. 1), or the conveyor belt may be arranged obliquely, and the height of the conveyor belt gradually increases in a direction away from the feed opening, and the oblique arrangement may perform a lifting operation on the powder material.

In addition, the material taker is rotatably mounted to the feed opening by means of a bearing (not shown).

In addition, the first power unit is a servo motor, and the second power unit is a speed reduction motor.
