Description

Technical Field

[0001] This utility model relates to the field of copper powder drying technology, and in particular to a rapid copper powder drying device. Background Technology

[0002] Copper powder, due to its excellent physical and mechanical properties, has wide applications in various industrial fields. Copper powder consists of fine copper particles with outstanding electrical conductivity. It is widely used in electronic components, conductive bumps, printed circuit boards, and other areas. Its fine particle structure provides highly efficient conductive channels, making it an important material with superior electrical conductivity. Drying conductive copper powder is a crucial step in its production.

[0003] Most copper powder processing and drying equipment on the market currently tends to cause copper powder to accumulate during the drying process, making it impossible to dry the copper powder evenly. This affects the drying effect and makes it inconvenient for operators to remove the dried copper powder, thus increasing the labor intensity of the operators. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a rapid copper powder drying device, which overcomes the shortcomings of the prior art and effectively solves the problems of copper powder accumulating together, making it difficult to dry the copper powder evenly, thus affecting the drying effect of the copper powder, and also making it inconvenient for operators to remove the dried copper powder.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rapid copper powder drying device includes a base plate, a first support plate welded to one end of the top of the base plate, and a second support plate provided at the other end of the top of the base plate. A drying cylinder is provided between the first support plate and the second support plate, and a cover plate is connected to one side of the outer wall of the drying cylinder. A rotating shaft is rotatably connected to the inner walls of both ends of the drying cylinder, and exhaust holes with filter screens fixed to the inner walls are opened at the top of the conical outer walls of both ends of the drying cylinder. A collar is sleeved and fixed to both ends of the shaft wall, and connecting rods distributed at equal intervals are sleeved and fixed to the annular outer walls of the two collars. A V-shaped plate is welded and fixed to the end of each connecting rod away from the collar.

[0007] Open the cover and pour the copper powder into the drying cylinder. By pushing the insert rod outward, the cover and the drying cylinder are secured through the insertion of the insert rod and the connecting block. The copper powder is dried by heating the lower half of the drying cylinder. During the drying process, a servo motor drives the rotating shaft to rotate. The rotating shaft drives the V-shaped plate to rotate inside the drying cylinder through the collar and connecting rod. The rotating V-shaped plate refreshes the copper powder accumulated in the drying cylinder through its protruding end, so that the lower half and upper half of the accumulated copper powder are swapped. After the copper powder is dried, open the cover and drive the rotating shaft to rotate in the opposite direction through the servo motor. The V-shaped plate rotates in the opposite direction and discharges the copper powder outward through its concave end.

[0008] Preferably, a groove is provided at the other end of the top of the base plate, and a handle screw is rotatably connected in the groove. A movable block that is screwed to the handle screw is welded and fixed to the bottom of the second support plate.

[0009] By rotating the handle screw, the screw drives the screwed movable block to move along the slide groove, thereby adjusting the distance between the second support plate and the first support plate.

[0010] Preferably, a servo motor is installed and fixed on the outer wall of the first support plate away from the drying cylinder, and the output shaft of the servo motor is connected and fixed to one end of the rotating shaft through a coupling. Both the first support plate and the second support plate are rotatably connected to the rotating shaft.

[0011] The shaft is rotated by a servo motor.

[0012] Preferably, the top two ends of the annular outer wall of the drying cylinder are respectively welded and fixed with fixing blocks, and a rotating rod is rotatably connected between the two fixing blocks, and one end of the cover plate is sleeved and fixed to the rotating rod.

[0013] The cover plate can be separated from or connected to the drying cylinder by rotating a rod.

[0014] Preferably, connecting blocks are welded and fixed at both ends of one side of the annular outer wall of the drying cylinder, and a connecting shell is welded and fixed at one side of the arc-shaped outer wall of the cover plate. Insert rods are inserted and movable at both ends of the connecting shell, and the insert rods and connecting blocks form an insertion fit.

[0015] By moving the insert rod, the cover plate and the drying cylinder are fastened together through the insertion of the insert rod and the connecting block.

[0016] Preferably, the V-shaped plate forms a sliding fit with the annular inner wall of the drying cylinder, and the length of the V-shaped plate is adapted to the width of the annular inner wall of the drying cylinder. Positioning rods distributed at equal intervals are welded and fixed to the outer walls of both ends of the drying cylinder along the annulus. The first support plate and the second support plate are both inserted into the positioning rods.

[0017] The rotating shaft drives the V-shaped plate to rotate inside the drying drum via a collar and connecting rod. The rotating V-shaped plate refreshes the copper powder accumulated inside the drying drum through its protruding end, while the V-shaped plate rotating in the opposite direction discharges the copper powder outward through its concave end.

[0018] The beneficial effects of this utility model are as follows:

[0019] By opening the cover plate and pouring copper powder into the drying cylinder, the cover plate is fixed to the drying cylinder lid. The copper powder is dried by heating from the lower half of the drying cylinder. During the drying process, a servo motor drives a rotating shaft to rotate. The rotating shaft drives a V-shaped plate to rotate inside the drying cylinder through a collar and connecting rod. The rotating V-shaped plate refreshes the copper powder accumulated inside the drying cylinder through its protruding end. After the copper powder is dried, the cover plate is opened, and the V-shaped plate rotating in the opposite direction discharges the copper powder outward through its concave end. This effectively solves the problem in the existing technology where copper powder accumulates together, making it difficult to dry the copper powder evenly, thus affecting the drying effect and making it inconvenient for operators to remove the dried copper powder.
