Description

TECHNICAL FIELD

[0001] The present application relates to the field of powder filling device, and particularly relates to a multi-channel powder filling device. BACKGROUND

[0002] The heat pipe powder filling device is a special equipment for filling powder in the heat pipe. The main purpose of powder filling is to increase the capillary action in the heat pipe, helping the working fluid to circulate better, so as to improve the heat transfer efficiency of the heat pipe. In the heat pipe, the micro pores and channels formed between the powder particles can act as capillary tubes to attract the working medium to flow back from the condensing section to the evaporating section, completing the heat cycle. This spontaneous circulation mechanism enables the heat pipe to work continuously without external power.

[0003] The existing powder filling device inserts the copper pipe with the core rod installed inside into the insertion hole on one side of the movable plate when operating. After the insertion is completed, the movable plate is rotated by 180 degrees. Then, the powder cup is lowered, and a plurality of powder cups are sleeved on a plurality of copper pipes. The powder is introduced from one side of the powder cup through a plurality of powder conveying hoses in the powder precise metering mechanism. Then, the plurality of copper pipes are vibrated under the action of the vibration device to realize the filling of the powder. The powder filling device with the above structure has the following problems when in use.

[0004] The inner wall of the powder cup is directly sleeved on the copper pipe. Since the powder cup needs to be sleeved on the copper pipe, there needs to be a certain gap between the inner wall of the powder cup and the outer surface of the copper pipe. The existence of the gap is easy to cause the powder leakage phenomenon in the powder filling process. In order to improve the uniformity of the powder filled into the copper pipe, the copper pipe needs to vibrate to a certain extent during the powder filling process. Therefore, the copper pipe and the powder cup produce relative displacement during the vibration process, thereby aggravating the powder leakage phenomenon.

[0005] Therefore, it is necessary to provide a new multi-channel powder filling device and a use method thereof to solve the above technical problems. SUMMARY

[0019] A specific use method of the above-mentioned multi-channel powder filling device comprises the following steps:

[0020] (1) Insert the copper pipe provided with a mandrel into the plurality of insertion holes;

[0021] (2) Drive the first gear to rotate by the second motor, so that the second gear drives the support column to rotate, under the action of the support column, the rotating plate drives the movable plate to rotate through the telescopic rod, so that the plurality of copper pipes are rotated to below the plurality of material receiving hoppers;

[0025] (6) the powder is moved to the inside of the fixed cylinder through the powder hose, then the powder is moved to the powder leakage hole and then to the bottom of the receiving hopper, and enters the gap between the copper pipe and the core rod.

[0026] Compared with the related art, the multi-channel powder filling device and the use method thereof have the following advantages

[0027] Advantages:

[0028] 1. Under the action of the eccentric wheel and the first spring, the relative movement between the moving plate and the vibrating plate occurs, and with the movement of the vibrating plate, the fixed cylinder and the movable cylinder move relatively, the powder is moved to the inside of the fixed cylinder through the powder hose, then the powder is moved to the powder leakage hole and then to the bottom of the receiving hopper, and enters the gap between the copper pipe and the core rod.

[0029] 2. When the vibrating plate vibrates, the first lifting plate moves, the first connecting plate moves through the insertion block, and the receiving plate moves through the first connecting plate. At this time, the receiving plate, the first lifting plate, the first connecting plate and the vibrating plate are relatively stationary and are in reciprocating motion. Since the bottom end of the copper pipe is supported through the limiting hole on the receiving plate, the top of the copper pipe abuts against the pressing surface, the copper pipe moves with the movement of the receiving plate, the movement trajectory of the copper pipe is the same as that of the receiving hopper, and the copper pipe and the receiving hopper are in a relatively stationary state, that is, the pressing surface always abuts against the top of the copper pipe and the bottom end of the receiving hopper is always located inside the copper pipe, so that the copper pipe is not easy to leak powder during the powder filling process, and since the copper pipe vibrates continuously during the powder filling, the distribution of the powder filled into the copper pipe is more uniform.

[0030] 3. When the device is used for filling powder, the receiving hopper, the copper pipe, the core rod and the receiving plate supporting the copper pipe move synchronously, and the whole is more integral. Compared with the traditional powder filling method in which the copper pipe and the powder cup move relatively, the device can protect the surface of the copper pipe, so that the copper pipe is not easy to be damaged due to friction, and the core rod can be relatively stably located inside the copper pipe, so that the core rod is not easy to deviate.

[0031] 4. When the movable cylinder reciprocates vertically, the movable frame and the movable rod of the fixed frame are not fixedly connected with the movable cylinder, but are connected with the movable cylinder through the second spring. When the movable cylinder moves up and down, the movable rod moves relatively under the action of the second spring, the bottom end of the movable rod moves in the powder leakage hole, and the end of the movable rod moves from above the powder leakage hole to below the powder leakage hole, so that the powder in the powder leakage hole is not easy to block.
