Description

Technical Field

[0001] The invention relates to the technical field of powder stirring mechanisms, and in particular to a powder stirring blade mechanism with a dustproof and heat-insulating cover plate. Background Art

[0002] In the process of handling powder materials, stirring is a crucial link. However, traditional powder stirring mechanisms often have problems such as insufficient dust prevention, easy material leakage, uneven stirring, and difficulty in effectively isolating the heat generated during the stirring process. Especially during the stirring process, powder materials are easy to adhere to the stirring mechanism and the inner wall of the stirring box, which not only affects the stirring effect, but also may cause damage to the equipment and increase maintenance costs. In addition, if the heat generated during the stirring process cannot be effectively isolated, it may also cause damage to components such as the stirring shaft, shortening the service life of the equipment. Summary of the invention

[0003] The purpose of the present invention is to solve the problem that the powder material in the prior art is easy to adhere to the inner wall of the stirring mechanism and the stirring box, which not only affects the stirring effect, but also may cause damage to the equipment and increase the maintenance cost.

[0010] In one possible design, the mixing assembly includes a mounting plate fixedly connected to the top of the outer cylinder, a servo motor is fixedly connected to the top of the mounting plate, an inner cylinder is fixedly connected to the bottom of the mounting plate, a plurality of fixing screws are threaded through the outer wall of the outer cylinder, one end of the fixing screws is in conflict with the inner cylinder, the bottom of the inner cylinder extends to the interior of the mixing box, a driving rod is rotatably connected to the bottom of the mounting plate, the output shaft of the servo motor is fixedly connected to the top of the driving rod, a stirring shaft is fixedly connected to the bottom of the driving rod, and a plurality of stirring rods are fixedly sleeved on the outer wall of the stirring shaft.

[0011] In one possible design, the recovery component includes an annular inclined plate fixedly connected to the outer wall of the stirring shaft, the outer wall of the annular inclined plate is fixedly sleeved with an outer sealing plate, the bottom of the sealing cover plate is fixedly connected with an L-shaped sealing gasket, and the L-shaped sealing gasket is located on the top of the outer sealing plate and used in conjunction with the outer sealing plate.

[0012] In one possible design, a material storage trough is provided inside the stirring shaft, a plurality of second side holes are provided on the outer wall of the stirring shaft, the second side holes are located inside the annular inclined plate and used in conjunction with the annular inclined plate, an arc-shaped groove is provided on the bottom inner wall of the material storage trough, a circular discharge hole is provided on the bottom of the stirring shaft, and interconnected strip holes are provided on the inner walls on both sides of the arc-shaped groove.

[0015] In a possible design, legs are fixedly connected to the four corners of the bottom of the mixing box, and anti-slip pads are fixedly connected to the bottoms of the legs.

[0016] In the present application, in the present application, when in use, the material is put into the interior of the mixing box through the feed pipe, and under normal circumstances, the bottom of the sliding cylinder is located inside the feed circular hole, and the top of the feed pipe is sealed to prevent the material from leaking out. When the material is fed in, the material enters the interior of the feed funnel. The setting of the feed funnel can help the material enter. At the same time, the weight of the material will push the sliding cylinder and the feed funnel downward, thereby causing the sliding cylinder to enter the interior of the feed pipe, and the spring is squeezed. At this time, the first side hole is connected to the feed pipe, and then the material enters through multiple first side holes, and finally is fed into the interior of the mixing box through the feed port, thereby improving the dustproof performance of the device;

[0017] At this time, the servo motor can be started, and the output shaft of the servo motor drives the driving rod to rotate, the driving rod drives the stirring shaft to rotate, and the stirring shaft drives the stirring rod to rotate, so that the internal materials can be fully mixed. At this time, the upper frustum block contacts the inner wall of the mixing box to prevent the material from being exposed. At the same time, the sealing rod blocks the discharge hole, and the sealing baffle blocks the discharge pipe, which further improves the sealing performance of the device to prevent the material from leaking.

[0018] At this time, most of the materials in the mixing box will be blocked by the outer sealing plate first, and the powder adhering to the outer wall will be thrown off due to the high-speed rotation of the outer sealing plate, and penetrate into the waste cavity between the inner sealing plate and the outer sealing plate through the gap between the outer sealing plate and the L-shaped sealing gasket. The setting of the annular inclined plate can help a small amount of material to slide through the second side hole to the inside of the storage tank for collection;

[0019] When discharging the material subsequently, the sealing cover plate can be lifted as a whole. At this time, the device as a whole, the invading material will be stored in the waste cavity to prevent it from entering the inner sealing plate and the bearing assembly, thereby achieving a sealing effect; and, due to the frictional heat generated during the rotation process, the powder entering the waste cavity will be heated and agglomerated, preventing it from continuing to diffuse. The waste cavity also reduces the impact of heat on the bearing cavity. At the same time, after the stirring shaft is lifted, the upper round table block is pushed upward. When the connecting rod is located inside the discharge circular hole, the waste inside can be discharged normally. The setting of the rotating plate makes it possible for the waste to only enter the interior of the storage tank, and it is difficult to move up and continue to leak out, which is convenient to use.

[0020] Beneficial effects: Improved dust-proof performance: By setting a feeding assembly, including a feeding funnel, a sliding cylinder, a spring and other components, it can be ensured that the material will not leak during the process of being fed into the mixing box, thereby improving the dust-proof performance of the device.

[0021] Ensure uniform mixing: By setting up a mixing assembly, including a driving rod, a stirring shaft and a stirring rod, efficient mixing of materials can be achieved to ensure uniform mixing.

[0022] Effectively isolate heat: By setting up components such as the inner sealing plate and the outer sealing plate, a waste chamber can be formed to collect powder materials attached to the stirring mechanism and the inner wall of the stirring box. At the same time, the waste chamber can also effectively isolate the heat generated during the stirring process and protect the stirring shaft and other components from damage.

[0023] Convenient waste recycling: By setting up recycling components, including annular inclined plates, storage tanks and connecting rods, waste can be easily discharged from the mixing box and recycled. This not only reduces the waste of waste, but also reduces the maintenance cost of the equipment.

[0024] Simple structure and convenient operation: The structural design of this application is reasonable, the connection between the components is tight and reliable, and the operation is simple. At the same time, this application can also be customized and improved according to actual needs to meet the needs of different users. BRIEF DESCRIPTION OF THE DRAWINGS
