Description

Horizontal shaftless mixing machine TECHNICAL FIELD

[0001] The present application relates to the technical field of mixing machines, and specifically relates to a horizontal shaftless mixing machine. BACKGROUND

[0002] At present, in the horizontal type drum mixer, the powder is lifted along the inner wall of the cylinder, or is mixed by the auxiliary mixing paddle of the device, and then falls along the surface of the powder to achieve mixing, that is, the radial convection of the powder in the cylinder is large; the axial mixing speed of the existing horizontal type mixing machine is much smaller than the radial mixing speed, so the mixing needs a long time and cannot meet the mass production;

[0003] In the existing powder mixing, the powder is blocked due to moisture or different powder surface friction, and the blocked powder not only blocks the mixing machine, but also affects the quality of the powder mixing and the subsequent production.

[0004] SUMMARY

[0005] The present application aims to provide a horizontal shaftless mixing machine to solve the problems in the prior art.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a horizontal shaftless mixing machine comprises a chassis, a first servo motor, a shaft coupling, a mixing mechanism, a second servo motor and a discharge mechanism, the chassis is fixedly connected with the first servo motor, the output end of the first servo motor is in transmission connection with the shaft coupling, the shaft coupling is in transmission connection with the mixing mechanism, the mixing mechanism is in rotary connection with the chassis, the second servo motor and the discharge mechanism are both fixedly connected with the mixing mechanism, and the output end of the second servo motor is in transmission connection with the mixing mechanism.

[0007] The mixing machine is used for mixing different powders together to make them reach a uniform state, the first servo motor outputs a torque, the torque is transmitted to the mixing mechanism through the shaft coupling, the mixing mechanism rotates, the mixing condition of the powder is detected, whether the powder is blocked due to moisture and other factors is detected, the second servo motor outputs a torque feedback to the internal mechanism for adjustment, the blocking is broken, and the completely mixed powder is output by the discharge mechanism, and the discharge mechanism can control the single discharge amount of the powder.

[0008] Further, the mixing mechanism comprises an outer cylinder, an opening and closing plate, an outer screw blade, a base, an inner screw blade, and a detection mechanism. The outer cylinder is provided with an inlet, an outlet, and a side hole. The opening and closing plate is rotatably connected to the inlet. The inlet is arranged on the outer cylinder near a side of the first servo motor. The outlet is arranged on the outer cylinder away from the first servo motor. The outlet is fixedly connected to the outlet mechanism. The detection mechanism comprises a plurality of groups. The plurality of groups of detection mechanisms are fixedly connected to the side hole. The plurality of groups of detection mechanisms are evenly distributed along the axis of the outer cylinder. The outer screw blade is fixedly connected to the outer cylinder. The base is drivingly connected to the output end of the second servo motor. The inner screw blade is fixedly connected to the base.

[0009] Different powders are injected into the outer cylinder through the inlet. The entire outer cylinder is driven to rotate around its axis through the shaft coupling. The powders are lifted along the inner wall of the outer cylinder by the outer screw blade and then fall down from the air. The powders are continuously lifted and fall to diffuse and mix uniformly. The output torque of the second servo motor drives the rotation of the inner screw blade. The rotation speed of the inner screw blade is greater than that of the outer screw blade. When the rotation speed of the inner screw blade is in the same direction, the falling powders from the outer screw blade are accelerated to return to the bottom of the outer cylinder by the inner screw blade. The circulation of the accelerated powders enables the powders to be mixed more uniformly. A part of the powders in centrifugal motion along the outer cylinder enters the detection mechanism through the side hole. The detection mechanism detects the caking of the powders and feeds back to the second servo motor. When the powders are caked, the second servo motor outputs a reverse torque. The falling powders from the outer screw blade are crushed by the gap between the inner screw blade and the outer screw blade. The falling speed of the powders is opposite to the direction of the inner screw blade, and the caked powders are broken by the impact of the inner screw blade.

[0010] Further, the inner diameter of the outer screw blade is in contact with the outer diameter of the inner screw blade. The pitch of the outer screw blade is greater than that of the inner screw blade. The number of threads of the outer screw blade is less than that of the inner screw blade.

[0011] The inner diameter of the outer screw blade is in contact with the outer diameter of the inner screw blade, which ensures that the caked powders can be crushed by the gap between the inner screw blade and the outer screw blade when the inner screw blade rotates in the opposite direction. The pitch of the outer screw blade is greater than that of the inner screw blade. The number of threads of the outer screw blade is less than that of the inner screw blade. The number of threads of the inner screw blade is greater than that of the outer screw blade, which enhances the effect of accelerating the powders and crushing the caked powders.

[0012] Further, the detection mechanism comprises a tube shell, a mounting frame, a pressure mechanism, a first-stage impeller, a second-stage impeller, a third-stage impeller, and a fourth-stage impeller. The tube shell is provided with a first inlet and a second inlet. The first inlet is arranged on the tube shell near the inlet. The second inlet is arranged on the tube shell away from the inlet. The mounting frame is fixedly connected to the tube shell. The pressure mechanism comprises four groups. The four groups of pressure mechanisms are fixedly connected to the mounting frame. The first-stage impeller, the second-stage impeller, the third-stage impeller, and the fourth-stage impeller are rotatably connected to one group of pressure mechanisms.

[0013] The mixed powder enters the inside of the shell from the first feeding port along the side wall of the outer cylinder. When the powder does not exist agglomeration, the powder will pass through the rotation of the first impeller, the second impeller, the third impeller and the fourth impeller, and then be discharged from the second feeding port back to the outer cylinder. When the powder exists agglomeration, the powder will be stuck on the impeller. With the continuous entry of the powder, the pressure exceeds the spring limit value in the pressure mechanism, and the weight of the powder accumulated on the impeller is detected by the pressure mechanism.

[0014] Further, the number of fan blades of the first impeller is less than that of the second impeller, the number of fan blades of the second impeller is less than that of the third impeller, and the number of fan blades of the third impeller is less than that of the fourth impeller.

[0015] Through the incremental number of fan blades of the first impeller, the second impeller, the third impeller and the fourth impeller, the size of the agglomeration allowed to pass through the second impeller is smaller than that of the first impeller, and so on. The fourth impeller cannot pass through the agglomeration. Through the analysis of the electric signals of the four groups of pressure mechanisms, the size of the agglomeration and whether the agglomeration exists can be judged.

[0016] Further, the pressure mechanism comprises a sliding column, a spring seat and a length measuring motor. The sliding column is rotationally connected with the first impeller, the second impeller, the third impeller and the fourth impeller. The sliding column is fixedly connected with the spring seat. The length measuring motor is fixedly connected with the spring seat. The output end of the length measuring motor is slidingly connected with the first impeller, the second impeller, the third impeller and the fourth impeller.

[0017] The powder drives the first impeller to rotate and slide from the fan blade gap of the first impeller. When the volume of the agglomerated powder exceeds the fan blade gap of the first impeller, the agglomeration will accumulate on the first impeller. When the accumulated powder continues to accumulate, the impact load exceeds the elastic limit of the spring seat. The first impeller slides along the sliding column. The length measuring motor slidingly connected with the first impeller recognizes the displacement and sends an electric signal. The pressure recognition principles of the first impeller, the second impeller, the third impeller and the fourth impeller and the pressure mechanism are the same.

The output end of the third servo motor and the output end of the fourth servo motor are drivingly connected with the distributing mechanism. The inlet pipe is provided with a first slope. The slope surface of the first slope faces the shell. The discharge pipe is provided with a second slope. The slope surface of the second slope faces away from the shell.
